Severe Emotional Disturbances (SED) Classrooms

Self-contained classrooms for students designated with emotional disturbances need to create a structured and safe environment for students with behavioral and emotional disabilities to learn appropriate ways to interact with peers and adults. The final goal of a self-contained program is for students to exit and join the general education population in regular classrooms. Students with SEDs may be included in general education classrooms with support from a special educator. In many cases, when a students behavior puts him or herself at risk or threatens typical peers, they may be placed in self-contained settings. Sometimes, when children have come to the attention of law enforcement because of violent or destructive behavior, they may return from some form of confinement to a residential program. Decisions are often made on LRE (Least Restrictive Environment) based on the safety of the student, peers, and teachers. Because these special placements are very expensive, many school districts look to self-contained programs to help students with Severe Emotional Disturbances re-enter the general education population. Critical Elements of a Successful Classroom Structure, Structure, Structure: Your classroom needs to exude structure. Desks should be in rows, evenly spaced (maybe even measure and mark each spot with tape) and should be aligned so that students cannot make faces at each other. Trust me, theyll try. Classroom rules and reinforcement charts need to be clearly displayed. Be sure that all materials or resources are easily available, and that your classroom layout requires as little movement as possible. Students with Emotional Disturbances will use sharpening a pencil as an opportunity to annoy a neighbor. Routines: I make no bones about the fact that I am a devotee of Harry Wongs excellent book, The First Days of School, which lays out ways to create routines for a classroom to run smoothly. You teach the routines, you practice the routines, and then you make very sure that everyone (even you) follows the routines and executes them with fidelity. Routines require a teacher to anticipate the sorts of challenges he or she will meet. Its wise for new teachers or new emotional support teachers to ask a veteran special educator to help them anticipate the kinds of problems that you will meet in an Emotional Disturbance program so you can build routines that will avoid those pitfalls. A Token Economy: A lottery system works well in general education classrooms to reward and reinforce appropriate behavior, but students in an Emotional Disturbance classroom need ongoing reinforcement for appropriate replacement behavior. A token economy can be designed in a way that connects it to individual behavior plans (BIP) or a behavior contract to identify target behaviors. Reinforcement and Consequences: A self contained classroom needs to be rich in reinforcers. They can be preferred items, preferred activities, and access to the computer or media. Make it clear that these reinforcers can be earned through following rules and appropriate behavior. Consequences also need to be clearly defined and clearly explained so students know what those consequences are and under what circumstances they are put in place. Obviously, students cant be allowed to suffer natural consequences, (i.e. if you run in the street you get hit by a car) but instead should experience logical consequences. Logical Consequences are a feature of Adlerian psychology, popularized by Jim Fay, co-author of Parenting with Love and Logic. Logical consequences have a logical connection to the behavior: if you tear up your shirt during a rant, you get to wear my ugly, ill-fitting shirt. Reinforcement needs to be things that your students actually find important enough to work for: although age appropriate is the mantra of the day, if behavior is extreme, the most important factor has to be that it works. Create menus of appropriate reinforcers from which students can choose. Choose or design reinforcers that you can pair with replacement behaviors. For example, a certain number of days with a certain number of points, and the student gets to eat lunch in the lunch room with a partner class. A certain number of day with a certain number of points might also earn a student the opportunity to invite a typical peer to play a game in the ED room.

Analysis Of August Wilson s Fences - 1840 Words

In today s society people have to deal with several issues that we can t explain. For some of us we built fences to isolate ourselves from others or in some cases to protect ourselves. No matter what the issue is we, all have to struggle to be able to provide for our families. As a child I built fences when it came to my feelings. For example, growing up I was in the chunky side. Since I wasnt so skinny like the pretty girls in my class. I kinda isolated my self from the other students. That way my feelings wouldn t get hurt.

Monetary, Fiscal and Exchange Rate Policy free essay sample

A study of the connection between monetary policy, fiscal policy, and the exchange rate policy. This paper explains monetary, fiscal and exchange rate policies separately, with definitions by different economists to balance the arguments. It is then followed by a discussion of their connection to each other, involving issues such as GDP, government expenditure, and interest rates. McDonald states monetary policy is the governments policy on setting the level of the money supply (1996: 149). It is the Reserve Bank of Australia (RBA)s attempt to change the quantity of money and interest rates so as to affect aggregate demand and, ultimately, equilibrium real GDP and the price level. Monetary policy, fiscal policy and the exchange rate policy are used by the RBA and by the Treasury to moderate fluctuations in a countrys economic growth rate and to maintain an appropriate trend growth rate. In todays world of floating exchange rates, it can be demonstrated that monetary policy is more effective at controlling macroeconomic conditions than fiscal policy is.

To monopolise the business, it is very important to make sure that the business is difficult for anyone to enter. But the WWF abondoned the territory leaving a chance for Ted Turner to enter the business. 1. Introduction 1. 1 Background of Wrestling World Wrestling Federation (WWF) is one of the most well known association in the world, especially, among men and boys.Many people may misunderstand that it is a gentlemen fighting club as well as other ones such as WBA, WBF or K-1. However, according to its owner, Vince McMahon Jr. , WWF is in an entertainment business, not wrestling one. The wrestling, originally showed in circus, has long history in American entertainment business. There are several regional wrestlers and promoters. Their domains are clearly divided and the gentlemens agreement to respect their domain and others had ruled for two decades, until Vince McMahon Jr. entered into the business.About Vince McMahon Vince McMahon Jr. followed his father footsteps became a wrestling promoter after he had struggled in bitter life with his stepfathers. Despite his father firstly discourage him to join the business, McMahon Jr. was fulled with inspiration and ambition to succeed in this business. Being trained by his father provided him valueable experiences which cannot be acquired through other promoters espectially the McMahons domain covered big cities like Washington, D. C. , Boston and New York City.Operating wresting matches in Madison Square Garden would be a great classroom for young McMahon, and also had a chance to study the television side of the operation. One fortunate day, he had a chance to try ring announcer because an absence of his fathers ringside announcers and his talent was recognised. By taking up this position full time, McMahon started to understand viewers wants. When McMahon Sr. was retiring as a result of cancer, McMahon Jr. had to buy the WWF outright instead of take it over from his father.The first move of McMahon was harsh and beyond the line of wrestling promoters that borders are no longer respected. 1. 3 Rising of the WWF In the first year of taking control the WWF, McMahon started to create next generation fans focusing on kids in town and tried to eliminate the border idea which had ruled wrestling for years. Television is the strongest and most effective influnce in such big country like the U. S. Soon, half of the country on the eastern coast could see the WWF at home. Certainly, McMahons breach of borders caused conflicts with other promoters.However, to win the competition was not as tough as it seemed. McMahon accurately estimated his competitors were lack of business experience. Most of them were former wrestlers and overestimated McMahon by the tremendous presence of the WWF in TV. As a result, these rivals gave up their territories and the WWF now broadcast across the country. After TV media achieved the WWF to counquer national territory, McMahon then move forward to cable network with a vision that this can increase revenues by pay-per-view, at the same time, it extends fan-club base.Merchandises and licensing revenues such as action figures, foam fingers, cereals and many other toys generated enomous amount of money from the popularity of the WWF. The WWF was not about only wrestling things anymore, opening the matches with rock concerts, explosions and excitement of speculators fascinate speculators and attracted millions of viewers at home. Growing together with the cable, the WWF became world-wide wrestling team. Japanese, Mexican and Canadian wrestlers were imported to the WWF and these contenders dared to do more dare-devil actions for fames and fortune.WCW: A New Challenger Ted Turner owned a cable television empire and broadcasted the WWF programme in his TBS station. Turner wanted to join the business with McMahon but the agreement could not happen, followed by the move away of the WWF from TBS and McMahon sold a territory out. Ted Turner then bought the territory and established the World Championship Wrestling (WCW). The WCW was an out-of-leage competitor at the first, but with capital reserve, cable networks and patience, he turned up to be a dangerous competitor McMahon ever faced.Eric Bischoff was a hero brought the WCW to superior the WWF. Bischoff attcked the weak point of the WWF which, at that time, struggled with the governments investigation of a steroid drug distribution scandal. As a result, many of WWF wrestlers were recruited to the WCW camp, started from former WWF superstars like Hogan and Savage, then stars on the stage like Lex Luger. The competition was getting intense for the WWF when a contract of its greatest wrestler, Bret Hart, was about to expire. McMahon offered an undenieable contract to Bret Hart to keep majority of the WWFs fans.Unfortunately, the outcome of the contract did not pay out. Fans strangely started to like a vilainous wrestler and Harts popularity was declining. Bret Hart turned not to be as worth as his paid. Hart could be neither a perfect hero nor a horrible villain. McMahon decided to cut the losses by shifting Hart to the WCW. Worse than that, conflicts between Hart and Shawn Michaels got too far to be just scripted. The competition between the WWF and the WCW had points to analyse and learn from it. 2. Case Analyses 2. 1 How did vince McMahon Build the WWF?Wrestling used to be stricted by a gentlemens agreement that not to invade other promoters domain. But Vince McMahon was a liberated promoter who started to break the agreement. McMahon took advantages of medias, his weak opponents and his territory was likely giving him better oppotunity. 1. Medias Firstly, he convinced a regional television station to broadcast his shows. The taped programme is possibly more attractive than live program because the shows is more intense, scenes are selected and exciting point can be replayed, zoom up or even re-filmed to make it better.In addition, almost everyhouse in the U. S. has television. Wrestling can be seen in by every one in the area, as easy as push a remote-control button. McMahon had a vision to use cable network to broadcast the WWFs shows. Cable was not only to extend the WWFs domain to oversea, but also unexpectedly bring back dare-devil wrestler from oversea. In addition, television was common way all over America to enter the others domain. Regardless of differences in states, American people are likely addicted to television. RAW, a Monday Night programme, was the extended programme from McMahon to tide fans with the WWF.Weak Opponents McMahon analysed his opponents correctly. Because he had been trained with his father before, this provided him deep understanding of other promotors background. In every competition, well understanding of opponent are crucial in order to defeat rivals. Most of promotors were former wrestler, lack of business experience. Moreover, at that time, wrestling was not the business generate revenues for the promotors so much thus low capital reserve was the other factor reduced endurance to compete in the business.McMahons opponents might think that it was not worth to compete with big promoter like McMahon for a low-income business, plus, they might not have knowledge to compete. 3. His territory McMahon had such a resourceful territory where cover major metropolitan on the eastern coast. Firstly, McMahons income would be relatively higher than other promoters due to a great number of population in the area. Dealing events with large corporates in New York City would give him incredibly greater experience than other promoters to organise business in environment that competition is cruelly intense.McMahon learned to use medias to manipulate market trend as same as other companies in New York do. McMahon had opportunities to learn, try and develop his business strategy. So, with his vision to dominate the business, his position provided him abundant resources to do so. Innovatively, the WWF presented viewers more than typical wrestling like others. McMahon carefully created fascinasting characters for his wrestlers. Each character has its own distinctive charisma. Wrestlers are clearly seperated into two groups: babyface (good guy) and chief heel (bad guy).Matches were about competing between good and evil, full of enthusiasm spectators cheered their wrestler. Regardless of the fact that the result of the fight were decided by McMahon, viewers were still keen to watch it because of charmful characters. Costumes also accent the characters personality. And the WWF was not only about wrestlers on the ring any more, but also the WWF wrestlers lifestyle were broadcasted, showing ordinary people participated in their life to show on TV, helping fans keeptrack of the alliances.This strategy wisely increased enthusiasm in the WWF fans, and create brand loyalty. McMahon expose wrestlers in his camp variously in other entermaint business such as movies and music. On the other hands, celebrities in these business were brought to present in the WWFs matches opening. The WWF matches provided more exciting shows than others: started with the rock concert, explosions, elevated platforms and breathtaking matches that everyone waiting for.Many wrestlers in the WWF becomes rock stars or movie stars. Hulk Hogan was a famous one and the recent one is the Rock who has several movies in Hollywood. Sometimes, the wrestlers were invited to present in talk shows, telling fans about their private life. This marketing strategy is to repeatedly shows the product (the WWF wrestlers) to consumers, generating familarity and increase visibility of product which increase purchasing possibility, in the other words, viewers become the WWF fans.

Educational Human Resources

There are various ways of looking at the cultural integration of the diverse population of the US. One view is that of the "melting pot," which proposes the people of different races and ethnicity should "blend together and assimilate into a common national culture" (Ivancevich and Gilbert, 2000, p. 75). A viewing countering this is to envision a "multicultural society," which suggests that different ethic groups can retain their culture and learn to coexist with each other (Ivancevich and Gilbert, 2000). While the "melting pot" scenario has been traditionally dominant among European-descended Americans, there has always been a strong undercurrent of multiculturalism (Ivancevich and Gilbert, 2000). Historians tell us that the US was never the homogenous culture that is presented by some traditionalists and conservatives. Diversity management is a concept that embraces the multicultural perspective. Within the field of education, it suggests that schools should not only consider the d iverse nature of its student population, but that administration policies should promote the "systematic and planned commitment" of the organization to "recruit, retain, reward and promote a heterogeneous mix of employees" (Ivancevich and Gilbert, 2000, p. 75). The demographics of the typical undergraduate student body have changed drastically over the course of the last decade. For example, one-third of American students are now minorities, which is up from 25 percent just a decade ago (Mellow, Van Slyck and Eynon, 2003). Forty percent of all undergraduates are now part-time students and 40 percent are over the age of 24, with 80 percent commuting to campus (Mellow, Van Slyck and Eynon, 2003). More than a quarter of these students are parents and 80 percent are employ, either full or part-time (Mellow, Van Slyck and Eynon, 2003).

7th Grade Science Fair Projects

7th Grade Science Fair Projects Seventh grade and middle school, in general, are a big time for science fairs because its a wonderful educational level for students to come up with ideas to explore using the scientific method and ways to investigate their questions. Parents and teachers still provide direction, especially helping students devise manageable experiments and appropriate work technology to present their results. However, the actual experiment should be done by the 7th grader. The student should record data and analyze it to determine whether or not the hypothesis is supported. Here are some ideas appropriate for the 7th-grade level. 7th Grade Science Project Ideas and Questions Use a prism to show the spectrum of visible light on a sheet of paper. Mark the endpoints, which is how far into infrared and ultraviolet you can see. Compare your visual range with that of other family members or other students. Is there a difference in range between genders? Do family members have a similar range? See if you can draw any conclusions ​using the scientific method.Composting is a great way to reduce waste and recycle nutrients, yet some household products and foods are contaminated with heavy metals and organic chemicals. Devise a test to measure one of these chemicals and compare the concentration in compost versus that in the ordinary soil in your yard.Houseplants can absorb and detoxify indoor pollution. Do research to identify which houseplants are best at cleaning the air in a home, office, or classroom. Now, take the project to the next level and determine which plants are most practical, affordable, and useful. Make a chart of the chemicals the plants cl ean, whether the plants are toxic to children and pets, whether they can live in low-light conditions or require bright light or special care, how much the plants costs, and whether they are readily available. Which brand of ibuprofen (or the student could test another type of pain reliever) dissolves the most quickly?Does the pH of juice change over time?Insects can sense light and dark. Can they still see light if its only red or blue, etc.?How well does a football helmet really protect against impact?

Its heat output?Does the mass of a baseball bat relate to the distance the baseball travels ? Is the paper towel brand that absorbs the most water the same as the brand that absorbs the most oil?

INDIVIDUAL ASSIGNMENT 2 SS Essay Example | Topics and Well Written Essays - 2500 words

INDIVIDUAL ASSIGNMENT 2 SS - Essay Example The Bendigo bank in Tambellup and Cranbrook is one such kind of social enterprise, rising from humble beginnings to give the two communities their identity. The creation of the community bank is attributable to two individuals, Vicki Brown and Jan Pope, after facing several challenges; they rode on motivating points to spearhead the creation of this bank in their respective community. Overcoming the Feat: Challenges and Motivations they faced. They were motivated by the lack of proper banking services that catered for the needs of the rural community, while listening to a certain show; they reaffirmed Louise Petschler’s concern over poor banking in the country. According to the latter, banking services had deteriorated to the extent that they had failed to provide fair and affordable basic services, additionally, they were providing these at high costs and with poor customer services while closing community branches. CHALLENGES The initiative by Vicki and Jane is typically a c ommercial interest although with a social context, they face numerous legal, financial, management and development challenges that a typical commercial business faces. However, due to the unique communal premise that the business is built upon, they face a considerably different set of challenges than a typical business faces (Fayolle and Harry 8). The key challenges that Vicki Brown and Jan Pope faced were stakeholder participation, balancing of their key objectives, raising finance, and recruitment of professional staff and expert advice Stakeholder participation The key stakeholders in this initiative were the 700 and 1100 members of community for the two towns Tambellup and Cranbrook respectively. Furthermore, the Bendigo Bank was an important participant in the process, this because the community bank would be a franchise of their own establishment. The process of convincing people to contribute money to investing in an enterprise that was yet to be created proved to be a daunt ing task to the two and the steering committee that was in charge of the launch. They were apprehensive that the failure of the business would subject to guilt and a lot of burden. The rural community who were to be bank’s customers was concerned about the confidentiality of their financial information; this was expeditiously addressed by the concerned parties. Pessimism that the locals had over the future of the bank coupled with the show that ABC was running at that time concerning failures of local initiatives. Balancing Key Objectives Vicki and Jan had noted that the agricultural communities in their small towns were being inconvenienced as they were forced to travel long distance to undertake this important service. The lack of facilities in the area affected several businesses in the area and not merely these two major sectors of the area’s economy; an estimated $26,000 was being lost per week to other towns. Any community initiative must strive to balance two ke y objectives, achieve the social purpose for which it was initiated and operate as a sustainable commercial entity (Kickul and Sophie 219). The problem the two initiators faced were the way in which to balance these two objectives. On the other hand, they worried that if the bank performed the first function

Effectiveness and Impact of Virtual Teams Essay Example for Free

Effectiveness and Impact of Virtual Teams Essay Technology is consistently evolving and impacting many organizations worldwide. It has changed many aspects in the workplace, including work styles, communication, and teamwork. Communication has been transformed into the ways of the virtual world, directly affecting group dynamics. Organizations often form teams of employees to serve a variety of purposes and reach goals in a more effective manner than independent work. Teams used to work strictly through face-to-face interactions, but with growing technology, virtual teams have been created and are used fairly often. â€Å"A virtual team is any team whose member interactions are mediated by time, distance, and technology. The core feature is not the technology, but that the team works together on a task while physically separated. Group members can communicate through e-mail, voice mail, video conferencing, electronic bulletin boards, and intranets.† (Levi, 2007, p. 258) Many research studies have been done to assess the effectiveness of virtual teams, examining the positive and negative aspects. This literature review is aimed to analyze several articles where researchers have explored many components of virtual teams and their impact. Vroman and Kovacich (2002) wrote an article that analyzed â€Å"the interactions of a virtual interdisciplinary team.† They explain computer-mediated communication (CMC) to be the basis of virtual teams, which they then compare to face-to-face teams. They examined the Interdisciplinary Training for Health Care for Rural Areas (ITHCRA) project, which is a team comprised of many different types of health professionals (e.g. clinical psychologist, nurse practitioner, nutritionist, etc.) The team’s ultimate goal was to develop an interdisciplinary health care curriculum, solely using CMC. ITHCRA functioned the same as any other team working together would, and faced the same challenges and developmental processes (forming, storming, norming, performing, and transforming). They additionally had to learn the ways of the new communication technology, which was an obstacle for many of the group members. The developmental process of the virtual team was similar to that of a face-to-face team, however, a number of differences were found. The forming phase was very  typical for team development. Team building and norm development took precedent of the project tasks initially. They had met face-to-face once, and after looking at their communication after this occurred, it was obvious they had formed social relationships and were more committed. This raised the question: what would have happened if the face-to-face meeting did not take place? It may have been more effective to have two groups in this study so comparisons could be made (e.g. one group solely virtual, the other group allowed 1-3 face-to-face meetings). It is hard to determine whether certain aspects of team development would have taken place without the opportunity to see their team members in a more personal way. Storming took place as well, which is when teams face certain conflicts. There were no apparent differences for this development in the virtual team. Norming, performing, and transforming phases of development all contributed to the team’s success and helped them complete their tasks and reach their goals. Vroman and Kovacich (2002) provided a good analysis of ITHCRA and the ways in which it was successful and where the members were challenged. They portrayed virtual teams as being more convenient, effective, and less time consuming when completing tasks. However, it allows for less personal contact and can be more difficult for some to communicate and fulfill the expectations of the group project. It may have been more effective to have ITHCRA communicate solely through CMC and compare them to a team with the same tasks and goals, but who communicated through a combination of CMC and face-to-face meetings. More valid results would be accessible to draw more accurate conclusions. It was interesting to use a interdisciplinary team, however, it may have acted as another variable besides CMC, which would then alter the results. Kirkman, Rosen, Tesluk, and Gibson (2004) conducted a research study on the impact of team empowerment on virtual team performance. â€Å"Team empowerment is defined as increased task motivation that is due to team members’ collective, positive assessments of their organizational tasks (Kirkman Rosen, 2002). They examined team empowerment through the teams potency, meaningfulness, autonomy, and impact to determine its’ impact on process improvement and customer satisfaction. Kirkman et al. (2004) studied a service organization that utilized high technology and frequently formed virtual teams to complete the company’s tasks and goals. Each team member had different roles within the organization and was separated from each  other geographically. The researchers moderated the effects of face-to-face meetings to examine the relationship between team empowerment and both process improvement and customer satisaction. Kirkman et al. (2004) used surveys, observation, a team empowerment measure they had created, and customer satisfaction and process improvement scorecards to test their hypotheses, which were that 1. Team empowerment will have a positive relation to virtual team process improvement, 2. Team empowerment will have a positive relation to virtual team customer satisfaction, and 3. The number of team’s face-to-face meetings will alter the relationship between team empowerment and process improvement (the fewer face-to-face meetings the stronger the relationship), and 4. The number of team’s face-to-face meetings will alter the relationship between team empowerment and customer satisfaction (the fewer face-to-face meetings the stronger the relationship). Their results indicated support for hypotheses one, two, and three, but did not support the fourth hypothesis. The researchers produced a well-designed study with significant, meaningful results that help contribute to the understanding of virtual teams. They operationally defined all of the terms and measures to provide an equal understanding for everyone. It seems that virtual teams have many positive characteristics that are more effective compared to the common face-to-face teams. With the rising technology, virtual teams may become the norm as researchers continue to understand their components and wire them for optimal success. Montoya-Weiss, Massey, and Song (2001) wrote an article on the findings of their research study. They â€Å"examined the effects of temporal coordination on virtual teams supported by an asynchronous communication technology.† They measured the mechanism â€Å"process structure† to determine the relationship between conflict management behavior and virtual team performance. They measured conflict management individually for each team member through a questionnaire they created. They defined their dependent variable, virtual team performance, as â€Å"the quality of the team rationale used to support the team decision.† They examined the range, depth, and organization for each team decision. Lastly, they observed and analyzed all communication among the virtual team. Montoya-Weiss et al. (2001) had five hypotheses total, which were tested through statistical analysis. They predicted that for all conflict management behaviors, a positive interaction would result.

The Fascinating Emperor Penguins Essay -- essays papers

The Fascinating Emperor Penguins Among the numerous different species of birds in the world one particular type stands out from them all. The emperor penguin reigns as one of the most interesting and unknown birds in scientists’ minds. The way that they conform and blend into the Antarctic environment, even during the harshest condition, underlines the uniqueness of these spectacular creatures. Scientists have been captivated by the amazing reproductive lives of the Emperor penguins, who live and behave in a way unlike any other animal in the world. Emperor penguins have baffled researchers and scientists for many years because of their unusual methods of mating amongst each other in extreme and some times harmful weather conditions. Under normal circumstances any other animal would not be able to survive in the extreme weather conditions that surround the penguins. Antarctica, where the penguins call home, is the coldest environment known on the earth. (Oeland 56) The breeding of the penguins begins in March when the ice is just beginning to harden underneath. During this time, scientists have been mystified at the audacity of the penguins to stay in the south as opposed to leopard seals and Adelie penguins that travel northward to warmer conditions. But, even though the penguins themselves make get chilled, they keep their chicks at a nice warm temperature. The eggs and chicks are incubated at a steady 98.8 degrees farenheight, and if a newborn chick is out of the parents’ warmth for more than two minutes it can f reeze to death. These harsh conditions intensify the danger and mystery of the penguins. The most interesting aspect of the Emperor penguins is their unique mating style that sets them apart from any other animal in the world. The entire process begins with a weeklong â€Å"courtship† session during the coldest months of the year. Unlike almost all other species of animals, the female initiates the mating process as opposed to the male penguin. Any type of communication carried on between the male and female is strictly audible. The penguins rely heavily on their acute sense of hearing and speech. The actual mating sequence occurs in the dead of cold, which astonishes many scientists and researchers. After the fertilization is through the female lays softball sized egg, and leaves to go search for food for two months. It is ... ... amazing creatures for several different reasons. Scientists are amazed at the idea that a creature can survive in the coldest environment on the planet for such a long period of time without moving great distances or hunting food. Ann Bowles of the Hubbs-Sea World Institute in San Diego believes that â€Å"compared with other marine birds, emperor penguins have everything backwards.† (Oeland 56) These birds are looked upon as issuing a new behavioral pattern among Antarctic animals of their kind. So far, though, not that many groups of new Emperor penguins have been found, when new group is found the discovery is tremendous news in the field. How long these birds will be able to survive in the chilling Antarctic conditions is unknown. But, there are several things that are known about these triumphant animals. The emperor penguins have been able to guide researchers and scientists into a world of understanding and questioning as to the penguins unique reproduction methods. The techniques and survival methods of the penguins have guided scientists onto a new path of exploration. But, overall, the emperor penguins have opened a new door into the unknown of Antarctic creatures.

Pathophysiology Of Dvt Formation Health And Social Care Essay

DVT is the consequence of a figure of factors that include stasis of blood, endothelial hurt and hypercoagulability of blood. PE is a major complication of DVT and occurs when a thrombus or blood coagulum detaches itself and is carried by the blood watercourse to the lungs. [ J32 ] Proximal DVT carries a higher hazard of PE than distal DVT. [ J30, Havig ] We focused on proximal DVT because it is much more faithfully detected by echography and is considered to be clinically more of import. [ J53: 11,12, c„?eK list, c?Ya?‚c†?a†¦Ã¢â‚¬ ? ] DVT can happen in any venas. ( near cervix, etc. ) However, it is non including in this literature reappraisal becauseaˆÂ ¦ Upper limb DVT is being reported, peculiarly associated with cardinal venous catheters. ( K66, from J20:54 ) After a shot, blood coagulums can organize in the venas of the legs ( deep vena thrombosis, or DVT ) . These coagulums can interrupt off and be carried in the blood watercourse to the bosom and lungs ( doing pneumonic intercalation ) . This can be life endangering. [ J30 ] Deep venous thrombosis may take to pneumonic emboli, a frequent cause of evitable deceases. [ K52, from J53:1 ]Virchow ‘s threeThe pathophysiological mechanisms underlying DVT include venous stasis and hypercoagulability linked to an addition in thrombin formation and thrombocyte hyperactivity ( Virchow 1858 ) . [ J30 ] The happening of one or more factors of Virchow ‘s three ( stasis of blood, endothelial hurt and hypercoagulability of blood ) in the venous system frequently leads to deep vena thrombosis ( DVT ) ( Virchow 1858 ) . [ J18 ] DVT = PE = ( a ¦Ã¢â‚¬Å¡e ¦Ã¢â‚¬ °?PEcs„incidence & A ; mortality rate ( acute + Rehab ) J43 P263 have ) Lower appendage DVT can be anatomically be divided into proximal DVT affecting the popliteal vena and proximal venas or distal DVT affecting the calf vena and distal venas. [ J59 ] DVT in the paralytic legs of patients with shot was reported every bit early as 1810 by Ferriar and once more by Lobstein in 1833. [ J45 ]Pathophysiology of DVT formationHarmonizing to the Medsurg, Venous return is aided by the calf musculus pump. When the legs are inactive or the pump is uneffective, blood pools by gravitation in the venas. Thrombus development is a local procedure. It begins by thrombocyte attachment to the endothelium. Several factors promote thrombocyte collection, including thrombin, fibrin, activated factor X, and catecholamines. In add-on, where the thrombocytes adhere to collagen, adenosine diphosphate ( ADP ) is released. ADP is besides released from the damaged tissues and disrupted thrombocytes. ADP produces thrombocyte collection that consequences in a thrombocyte stopper. Deep vena thrombi vary from 1mm in diameter to hanker cannular multitudes registering chief venas. Small thrombi are found normally in the pocket of deep vena valves. As thrombi become larger in diameter and length, they obstruct the venas, the ensuing inflammatory procedure can destruct the valves of the venas ; therefore ; venous inadequacy and postphlebitic syndrome are initiated. Newly formed thrombi may go pneumonic emboli. Probably 24 to 48 hours after formation, thrombi undergo lysis or go organized and adhere to the vas wall. Lysis diminishes the hazard of embolization. Pulmonary emboli, most of which start as thrombi in the big deep venas of the leg, are an ague and potentially deadly complication of DVT. Venous thrombosis is the procedure of coagulum ( thrombus ) formation within venas. Although this can happen in any venous system, the prevailing clinical events occur in the vass of the leg, giving rise to deep vena thrombosis, or in the lungs, ensuing in a pneumonic embolus ( PE ) . [ J56 ] In fact, approximately 90 % of DVT are of the go uping type. The possible for intercalation depends on the velocity and the extent of the moral force, go uping coagulum turning procedure. Almost all clinical PE originate from distal DVT. Merely the staying 10 % are derived from coagulums without connexion to the lower leg venas ( e.g. stray iliac vena thrombosis, transfascial great or little saphenous vena thrombosis, subclavian vena thrombosis, or catheter-related thrombosis ) . [ J58 ] Damage to the epithelial cell liner of the blood vas is one of the extrinsic factors triping the curdling cascade. The damaged endothelium efforts to keep vascular unity by adhesion and collection of thrombocytes. As the coagulating cascade continues, the concluding measure is the formation of thrombin, which leads to the transition of factor I to fibrin and the formation of a fibrin coagulum. ( Arcangelo & A ; Peterson, 2006 ) ( from K84, J40: Arcangelo ) Abnormal blood coagulums that adhere to the vas wall are known as thrombi. These are composed of blood cells, thrombocytes, and fibrin. Arterial thrombi are composed chiefly of thrombocyte sums and fibrin. Venous thrombi are composed of chiefly ruddy blood cells. The difference in composing is caused by the conditions in which the thrombus signifiers. In the arteria, the blood flow is high in comparing with the low flow conditions in the vena. The thrombus may go big plenty to interfere with blood flow within the vena or arteria. ( Mansen & A ; McCance, 2002 ) ( from K85, J40: Mansen ) If the thrombus detaches from the vas wall, it becomes an embolus. This nomadic coagulum travels thought the circulation until it lodges in a blood vas that is smaller than the coagulum. Distal to this point, blood flow is blocked and tissues or variety meats are deprived of O and nutrition. ( Mansen & A ; McCance, 2002 ) . The marks and symptoms associated with an embolus depend on the vena or arteria where Thursday coagulum becomes lodged. ( from K85, J40: Mansen ) In 1856, Virchow described the factors that predispose to venous thrombosis, including stasis, vascular harm, and hypercoagulability. These three factors are referred to as Virchow ‘s three. Stasis of blood may happen because of stationariness, age, fleshiness, or disease procedures. Trauma ( including surgery ) , endovenous ( IV ) canulation, medicines, and toxins are some of the many beginnings that may precipitate vascular harm. Hypercoagulability of the blood may be caused by assorted disease procedures and medicines. ( Mansen & A ; McCance, 2002 ) ( from K85, J40: Mansen )Why focal point on DVT instead than PE and VTE?A high proportion of patients with DVT besides have subclinical PE. [ K15, from J45:14 ] Most of the PE consequences from DVT ( delight happen literature to support ) Since lower limb DVT is the major beginning of PE, and the feature of prolong bed remainder of shot, this literature reappraisal will chiefly concentrate on the DVT at lower limbs. Approximately two tierces of these are below-knee DVTs, in contrast to unselected ( nonstroke ) patients showing with diagnostic DVT, in whom the bulk are proximal. [ J43 ] Most surveies show that PE seems to be much more common in patients with proximal and diagnostic DVT. [ K41, from J46:1 ] Clinical symptoms of DVT were developed by six patients ( oedema or hurting of the lower appendage, no instances of PE ) . ( out of 28, =21.4 % ) ( J48 ‘s consequence )Why shot patient easy to hold DVTThe general shot population is at hazard for DVT because of the undermentioned factors. First, there is an change in blood flow due to failing in the lower limb and a ensuing hypercoagulable province related to alterations in the blood. Second, vessel wall intimal hurt occurs related to alterations in blood and blood flow. Stroke patients may besides hold similar symptoms associated with DVT, such as swelling and Homan ‘s mark, that may be misinterpreted as being related to the shot. [ J50 ] Stroke patients are frequently bed-ridden, particularly during the acute stage, because of paresis. [ J50 ] Most of the shot patients are aged. ( age & gt ; ) , while aging is a important factors of the happening of DVT. Patients with shot are at peculiar hazard for developing deep venous thrombosis ( DVT ) and pneumonic intercalation ( PE ) because of limb palsy, prolonged bed remainder, and increased prothrombotic activity. [ J45 ( besides codification at J51 ) ] Sioson et Al. [ 46 ] reported 19 DVT events in the paretic limb, nine bilateral events and four contralateral in 32 patients prospectively followed. ( K49 from J46:46 )Why of import to forestallWHO estimates that 15 million people have a shot every twelvemonth, and this figure is lifting. ( K91, from J39:2 ) Venous thromboembolism is a common but preventable complication of acute ischemic shot, and is associated with increased mortality and long-run morbidity and significant health-care costs for its direction. ( K92, from J39:6 ) Without venous thromboembolism prophylaxis, up to 75 % of patients with unilateral paralysis after shot develop deep vena thrombosis and 20 % develop pneumonic intercalation, ( K93, from J39:8 ) which is fatal in 1-2 % of patients with acute ischemic shot and causes up to 25 % of early deceases after shots. ( K94, from J39:9 ) low molecular weight Lipo-Hepin and unfractionated Lipo-Hepin are hence recommended in guidelines from adept consensus groups.10-14 ( K95, from J39:10-14 ) The best intervention for VTE is bar. [ J34 ] Cause preventable decease [ J06 ] Deep venous thromboembolism ( DVT ) is an of import wellness issue in the hospitalized patients that leads to increased length of stay, morbidity, and mortality. [ J50 ] Early sensing of DVT is of import because of the hazard of pneumonic intercalation and its potentially fatal effects. However, it is good known that clinical characteristics of DVT and PE are notoriously nonspecific. [ J09 ] Despite betterments in bar ( SPARCL 2006 ) , small advancement has been made in handling shot with specific intercessions once it has occurred. ( K72, from J44 ) the happening of venous thromboembolism was about double higher in patients with an NIHSS mark of 14 or more than in those with a mark less than 14 ( in line with old studies25 ) ( K99, from J39:25 + J39self ) Patients with intracerebral bleeding ( ICH ) or ischaemic shot are at high hazard for development of venous thromboembolism ( VTE ) . ( K103, from J29:1 ) In comparing to patients with ischaemic shot, the hazard for VTE is higher in the haemorrhagic shot population. ( K104, from J29:2 ) Without preventive steps, 53 % and 16 % of immobilized patients develop deep venous thrombosis ( DVT ) or pneumonic intercalation ( PE ) , severally, in this population. ( K105, from J29:3 ) One survey detected DVT in 40 % of patients with ICH within 2 hebdomads and 1.9 % of those patients had a PE.4 ( K106, from J29:4 ) Development of VTE in the patient with ICH adds farther damaging complications to an already deadly disease with a 1-month case-fatality rate of 35 % to 52 % .5 ( K107, from J29:5 ) DVT besides prolongs the length of infirmary corsets, holds rehabilitation plans, and introduces a possible hazard for PE. ( K108, from J29:6 ) DVT prolongs hospitalization and additions health care costs. [ J01 ] DVT is the pathophysiological precursor of pneumonic intercalation ( PE ) . However, half of the DVT instances were symptomless. [ J01, K1 from J37:18, J37, J27 ] . Approximately one tierce of patients with diagnostic venous thromboembolism ( VTE ) manifest pneumonic intercalation ( PE ) , whereas two tierces manifest deep vena thrombosis ( DVT ) entirely. Furthermore, decease occurs in 6 % of DVT instances and 12 % of PE instances within 1 month of diagnosing. [ J46, J27 ] Clinically evident DVT was reported in 1.7 % to 5.0 % of patients with shot. Subclinical DVT occurred in 28 % to 73 % of patients with shot, normally in the paralytic limb. [ J45 ] The frequence of symptomless PE in patients with DVT to be 40 % . [ J50 ] Prevention of VTE is extremely effectual in take downing the morbidity and mortality rate of shot patients since PE histories for up to 25 % of post-stroke early deceases. [ J43 ] Boundaries JV, Wiebers DO, Whisnant JP, Okazaki H: Mechanisms and timing of deceases from intellectual infarction. Stroke 1981, 12:474-477.The rate of PE is likely to be underestimated because they are non routinely screened for, and necropsies are seldom performed. Fifty per centum of patients who die following an acute shot showed grounds of PE on necropsy. [ K68, from J13:7 ] The one-year incidence of DVT in the general population is estimated to be about 1 per 1000 ( 8 ) , nevertheless, it should be noted that much of the published informations are derived from patients who present with symptoms at medical establishments. Diagnosis of DVT has traditionally been based on clinical presentation, nevertheless, grounds from post-mortem surveies indicates that a significant proportion of VTE instances are symptomless. [ K10 from J55 ] Clinically evident DVT confirmed on probe is less common but DVTs may non be recognised and may still do of import complications. Pneumonic intercalation ( PE ) is an of import cause of preventable decease after shot [ K67, from J13:4 ]

Assessment and Learners Essay

4 Understand how to involve learners and others in assessment 4. 1 Explain the importance of involving the learner and others in the assessment process Assessment is all about making judgements. A major argument for involving students in self and peer-assessment is that it helps them to develop the ability to make judgements, in particular about themselves and their work. This is an important life skill as well as an academic one. If an assessor wants to observe a specific piece of evidence but is unable to because maybe it hasn’t occurred in any methods of assessment; this is where it’s important for others to get involved for example the managers or the colleagues. The workers can motivate the learner when the assessor is not around. The workers can act as an expert witness, so when the assessor goes to visit the candidate he/she could provide the assessor with a witness testimony, and this will be put as evidence in the portfolio 4. 2 Summarise types of information that should be made available to learners and others involved in the assessment process Students should be made aware of the criteria in which they will be assessed from the start of the course as well as the forms of assessments that will be used during the process and the length of time it will take. The learners should be given information on what the outcome will be for the different assessments undertaken as well as what qualification is expected on completion of the course. 4. 3 Explain how peer and self-assessment can be used effectively to promote involvement and personal responsibility in the assessment of learning There are many benefits of peer assessment. Students assessing each other’s learning can help the learners to feel supported by their peers. There is also the benefit that the learners may be able to relate more easily with their peers than with a tutor. Peer assessment assists the learners gain confidence and social skills and shares the roles of assessing and being assessed equally between the learners. One suggested peer assessment activity is to have students work in groups, discussing each other’s’ in-class assignments and ways to improve, develop and adapt for improvements providing their peers with peer led feedback and assessment. Self-assessment is a natural progression and grows out of peer assessment. It allows the students to examine their own work and discover strengths and weaknesses for themselves. This can be carried out through reflective practice through a diary of learning or learning log that allows the student to see progression and reflect upon the journey. It’s important to incorporate some aspect of self-assessment every day, if possible, in order for students to take responsibility and interest in their abilities. Another way of using self-assessment is by asking the students to give themselves a grade on the work that they have completed before handing in the work to the marking criteria set, or for student looks at their assignment and marks green for questions that they feels confident about, yellow for questions that they are unsure of and red for questions that will require help. 4. 4 Explain how assessment arrangements can be adapted to meet the needs of individual learners Assessment arrangements can be adapted by allowing the learners to have an element of choice on how the criterion is assessed. This will allow the learners to feel included and means that the tutor is not offering an alternative or necessarily forcing the learner to disclose their lack of understanding or forcing adjustment. An example would be giving all learners the choice of having a Unit assessed either by portfolio or by written examination or by observation. In short, as long as the assessment criteria are being assessed to the same standard, the assessment method can be flexible and should meet the needs of the learners 5 Understand how to make assessment decisions 5. 1 Explain how to judge whether evidence is: sufficient, authentic and current All assessments must be valid, reliable, practicable, and equitable and assessors must apply the standards of assessment uniformly and consistently. . Ensuring assessments are capable of generating sufficient evidence for learners’ to demonstrate that they have met the assessment criteria. Having this process gives the learners clear instructions to the assessments that will be used during the course as well as clear and precise guidelines for completion. It gives both the tutors and the learners the recommended guidelines on how work for the course should be presented and what evidence is required for verification, this in turn allows the tutor and the organisation to map the developments of the learner through the assessment criteria being met. This ensures that all courses awarded are valid and that the course has worked to the set Quality Assurance of the awarding body and organisation; thus being assessed accurately, consistently and fairly to set standards. Sufficient evidence must cover all aspects of the assessment criteria for each unit the learner is seeking to achieve and collect enough evidence to demonstrate knowledge and competence. The learner must be able to show that the work produced is authentic and able to explain and substantiate the evidence the learner has put forward. It is important, therefore, to ensure that any work that the learner submits is only evidence relating to your own performance. Current’ means evidence relating to skills, attitudes and knowledge you can currently demonstrate in relation to the criterion and unit being taught. 5. 2 Explain how to ensure that assessment decisions are: made against specified criteria, valid, reliable and fair The assessor should follow as far as possible the criteria set down in the relevant unit and qualification. All qualifications go through a standardisation process that enables each assessor to consistently make valid decisions; that all assessors make the same decision on the same evidence base and all candidates are assessed fairly. All corresponding evidence from the learner should be reliable in that they have concrete knowledge and skill to back up their evidence. The evidence should be fair in that any leaner will have the same opportunity to complete the assignment.

Free Essays on Kennedy

Kennedy came to office with flair. He offered a new vision and a new frontier for America. He also inherited a secret war in Cuba, a Cold War with the Soviet Union and China, and an emerging crisis in Southeast Asia. He preferred a flexible security strategy over Eisenhower's heavy-handed nuclear threats. Flexible Response was no highly explicit theory nor written in a single authoritative source. Flexible Response was realistic in that nuclear weapons couldn't be used. It tried to provide credible means to match non-nuclear escalation. The word "flexible" stressed the value of having "multiple options" available should a crises arise. Having multiple options during a crisis appeared to be better than reference to a few preset war scenarios. Having multiple options was thought to enhance the credibility of the U.S. deterrent (reassuring allies while deterring the opponent). At the same time, however, flexibility made it also improbable that the U.S. would want or need nuclear attack. In effect Flexible Response called for the continued presence (in Europe) of sizable conventional forces. Conventional forces were to serve two functions, a deterrent function and the function to fight limited wars. The main argument of the Eisenhower administration had been that conventional forces were too costly and nuclear weapons would have "more bang for the buck." Kennedy wanted to deter all wars, general or limited, nuclear or conventional, large or small. Eisenhower and Dulles wanted to achieve similar goals but at minimal cost. Their risk was to either not act at all or respond at all levels of threat beyond the original provocation. Kennedy disregarded costs and emphasized sufficient flexibility to avoid either escalation or humiliation.

With him he would bring a much more aggressive attitude than that of his predecessor former President Dwight D. Eisenhower. President Kennedy had only one down fall and it was that he worried about what others thought of the United States. Throughout his presidency President Kennedy would face many crisis. Some crisis would be very small and take very little time to resolve, while others would be on an imaginable scale and take years to end. The Cuban Crisis is one of the most noticeable that President Kennedy faced during his time as President. This conflict would also show an example of the role some nations play that may be they should not have. The Cuban Conflict would prove to be a stepping-stone for President Kennedy. Through his actions President Kennedy would show the world that the United States would do what ever it takes to stand up for what is right. President Kennedy would team up with Robert S. McNamara, Secretary of Defense and together they would launch the greatest arms role the world had ever known. This would cause the Russians to come to the aid of Cuba. President Kennedy explained to the Russians that if they got involved they would see their own fate. Though President Kennedy may have over reacted with the Cuban Conflict, by his actions being based on the fear of what the world thought, he still showed tremendous will power and fearlessness even when the odds were against him. The Cuban Crisis would also show the role that other nations would play in a certain crisis that should not have been played. The crisis in Cuba was a prime example of how during the world war countries would take a role that they should not have. The United States played a role they were not familiar with for the first time. They played the aggressor and moved in on Cuba. This action would prove not to be in the best interest, since Russia would come to the aid of Cuba. If the Uni... Free Essays on Kennedy Kennedy came to office with flair.

A Man for All Seasons Summary and Characters

A Man for All Seasons Summary and Characters A Man for All Seasons, a play written by Robert Bolt, retells the historic events surrounding Sir Thomas More, the Chancellor of England who remained silent regarding Henry VIIIs divorce. Because More would not take an oath which essentially endorsed the kings separation from the church in Rome, the Chancellor was imprisoned, tried, and eventually executed. Throughout the drama, More is forthright, witty, contemplative, and honest. Some might argue that he is too honest. He follows his conscience all the way to the chopping block. A Man for All Seasons asks us, How far would we go to remain honest? In the case of Sir Thomas More, we behold a man who speaks with utmost sincerity, a virtue that will cost him his life. The Basic Plot Shortly after the death of Cardinal Wolsey, Sir Thomas Moore, a wealthy lawyer and loyal subject of King Henry VIII, accepts the title of Chancellor of England. With that honor comes an expectation. The King expects More to sanction the divorce and his subsequent marriage to Anne Boleyn. More is caught between his obligations to the crown, his family, and the tenants of the church. Open disapproval would be an act of treason. Public approval would defy his religious beliefs. Therefore, More chooses silence, hoping that by staying quiet he can maintain his honesty and avoid the executioner as well. Unfortunately, ambitious men such as Thomas Cromwell are more than happy to see More crumble. By treacherous and dishonest means, Cromwell manipulates the court system, stripping More of his title, wealth, and freedom. The Character of Sir Thomas More When writing an essay about a literary work, students would be wise to analyze the character arc of the protagonist. Most main characters undergo a transformation. However, one could argue that Thomas Moore, the man who remains consistent throughout the seasons (in good times and bad), does not change. If you are looking for an essay topic in response to A Man for All Seasons, consider this question: Is Sir Thomas More a static character or a dynamic character? Many aspects of Mores nature hold steadfast. He demonstrates devotion to his family, friends, and servants. Although he adores his daughter, he does not give in to her desire to marry until her fiancà © repents his so-called heresy. He exhibits no temptation when offered bribes and contemplates no underhanded schemes when faced with political enemies. From beginning to end, he is forthright and honest. Even when locked away in the Tower of London, he politely interacts with his jailers and interrogators. Despite these almost angelic characteristics, More explains to his daughter that he is no martyr, meaning that he does not wish to die for a cause. Rather, he fervently maintains his silence in hopes that the law will protect him. During his trial, he explains that the law mandates that silence must be legally perceived as consent; therefore, More argues, he has not officially disapproved of King Henry. Yet, his opinion is not quieted forever. After losing the trial and receiving a death sentence, More decides to explicitly reveal his religious objections to the Kings divorce and second marriage. Here, students may find evidence of a character arc. Why does Sir Thomas More voice his position now? Does he hope to persuade others? Is he lashing out in anger or hatred, emotions he has kept in check until now? Or does he simply feel as though he has nothing more to lose? Whether Mores character is perceived as static or dynamic, A Man For All Seasons generates thought-provoking ideas about honesty, morality, law, and society. The Supporting Characters The Common Man is a recurring figure throughout the play. He appears as a boatman, a servant, a juror, and many other everyday subjects of the kingdom. In each scenario, the common mans philosophies contrast with Mores in that they focus on day-to-day practicalities. When More can no longer pay his servants a living wage, the Common Man must find work elsewhere. He is not interested in facing extreme hardship for the sake of a good deed or a clear conscience. The devious Thomas Cromwell exhibits so much power-hungry maliciousness that audiences will want to boo him off the stage. However, we learn in the epilogue that he receives his comeuppance; Cromwell is charged with treason and executed, just like his rival Sir Thomas More. Unlike the plays blatant villain Cromwell, the character Richard Rich serves as a more complex antagonist. Like other characters in the play, Rich wants power. However, unlike the members of the court, he doesnt have any wealth or status at the beginning of the play. He waits for an audience with More, eager to obtain a position in court. Although very friendly with him, More does not trust Rich and therefore does not offer the young man a place in court. Instead, he urges Rich to become a teacher. However, Rich wants to attain political greatness. Cromwell offers Rich the chance to join his side, but before Rich accepts the shady position, he desperately pleads to work for More. We can tell that Rich genuinely admires More, yet he cannot resist the lure of power and wealth which Cromwell dangles in front of the young man. Because More senses Rich is untrustworthy, he turns him away. Rich eventually embraces his role as a scoundrel. During the final courtroom scene, he provides false testimony, dooming the man he once revered.

One of the major aim of the Triangle casual shoe wear product is to be able to provide a better quality rang product to the triangle solutions customers. This means that the business will be able to meet the target of getting the product in different countries like Brazil, United Kingdom, China and France. It is a well-known fact that the Chinese market is of the most reputable in the world especially due to its economic cost in the market. France is also famous for its designer wear while brazil has a great market for snicker shoe products that include other forms of footwear. There are also other manufacturers who produce a huge selection of fashion footwear for both men and women in the countries (Burton, Parker, & Lawley, 2012). The product will mainly focus on the united states industry because it is the native home for the triangle solutions meaning that it will be easy to deal with the suppliers in the best way and also be able to get better quality and price. The relationship that the product will create with its competitors will be mostly focussed on the price and market position. In some of the markets, competitor will be found to have reach what is commonly referred to as a modus vivendi, this means that in this situation there are generally understood rules on how competition with other products occur. Market size will also mean that the product will have to look at the value to which the product offers the consumers. The less stable the market size, the greater the rate at which the price of the new product will be determined (Burton, Parker, & Lawley, 2012). There

Societal Changes - Assignment Example We just know we do not want any part of it. Introduction The issue of stereotyping, which also leads to a form of racism, can be seen in both the population and within the police force and the type of interactions that occur. When looking for someone to blame for why certain crimes happen, it is easy to think automatically that if someone thinks, looks and acts within a narrow visual framework, then it is easy to blame that person and that group of people (Bradshaw & Roseborough, 2005). The issue of Muslims has a tender spot in the minds of many Americans who see all Muslims as perpetrators of bombings and terrorism in the country. Whenever something happens in the country, people automatically assume it was done by a Middle Eastern Muslim terrorist. As we have also seen, the bomber can also be a Western Muslim terrorist, such as in the case of the Shoe Bomber in 2001 (Elliot, 2002). 1.With the recent bombing of the Boston Marathon, and the near-beheading and death of a British soldi er on a London street, tensions have been running high with the public, particularly in England. There have been numerous protests, and police, both in England and in the United States, have been told to look for groups of people, who might commit crimes against Muslims directly, or on or around property owned by Muslims. It is very hard for people to understand that when one, or a few, members of a group have committed a crime against others, it does not mean that all people of that group will be doing that same sort of crime (Gabbidon & Greene, 2013). When people look for the enemy, the only thing they have to go on is what the enemy would typically look like. In a war, one side knows that a certain uniform represents the enemy, and that there may be other physical identifications, such as an Asian appearance, for wars conducted in World War II and Vietnam. In a more modern day, and in modern warfare conducted today, appearances are far more deceiving and it is hard to know who th e enemy is. Some have dressed up in Western army uniforms and then turned guns on unsuspecting Western soldiers. Even seeing women with burkas and, especially with full face veils, promotes the concept of hiding something that makes identification possible (Moore, 2010). Therefore, those who hide behind veils, or ski masks, are potentially considered an enemy. It would be easy to suspect that some other person may be under that burka and veil besides a normal Muslim woman. While in Muslim countries, veils are rarely given a second thought, in Western countries, it is important for Muslim people to respect parts of the society they are now living in, and to let women remove the veil so it is not so threatening. Integration with their new society is essential to their success. Living as if they were still in their own land and observing their own rules without regard to the new country, is not acceptable (Moore, 2010). 2. There are several solutions to the issue of racial profiling. A ) In the first case, Muslims can take matters into their own hands by meeting law enforcement members of their community and getting to know the neighborhood police who conduct regular beats in the area (Bradshaw & Roseborough, 2005). Making friends, or at least, acquaintances, allows the police: to 1) know who they are individually; 2) establish

Protective Effects Of Fluoride Toothpastes Health And Social Care Essay

Protective Effects Of Fluoride Toothpastes Health And Social Care Essay The main aim of this report is to discuss the evidence for the protective effects of fluoride toothpastes and varnishes. In addition, I will discuss their application and mode of action. To begin with, I will give a brief history of fluoride and how it fits into the reversal of tooth decay. I will discuss fluoride varnishes namely Duraphat, Fluor Protector and Duraflor and their effect on the DMF Index and their roles in school based prevention programmes. There are other varnishes such as Lawefluor and Bifluorid but these are less commonly used and therefore, I will not be discussing them. After discussing fluoride varnishes, I will consider fluoride toothpastes. I will give a description on the composition of a typical toothpaste and the effect of fluoride toothpastes on the DMF Index. In addition, I will discuss the effects of high fluoride concentration toothpastes. Finally, I will compare both toothpastes and varnishes.

Fluoride is a negative ion of the element fluorine and is found naturally in water, foods, soil, and minerals such as fluorite (calcium fluoride) and fluorapatite. Fluoride can also be synthesised in laboratories where it can be added to oral hygiene products and to water. Fluoride utilisation has occurred in two phases: before water fluoridation in the 1950s and after the widespread use of fluoridated dentifrices in the 1980s (Cury, Tenuta 2008) when less than 10% of toothpastes contained fluoride compared with 96% at present. Fluoride is most effective post-eruptively (Oganessian, Lencova Broukal 2007) where the effects are generally topical and therefore, it is important for a constant fluoride concentration to be maintained in the oral environment. Topically applied fluoride provides high concentrations of fluoride to surfaces of the denti tion. This provides a local protective effect and prevents ingestion of large amounts of fluoride. (Marinho et al. 2004) Deposition of fluoride in enamel During apatite crystal formation, low concentrations of fluoride are incorporated into the tooth structure. This leads to supersaturation with respect to fluoridated hydroxyapatite: {{66 ten Cate,J.M. 2008) Ca10(PO4)6(OH)2+ F-= Ca10(PO4)6(F)2 + 2OH- (Fluorapatite) After calcification is complete and prior to eruption, additional fluoride is taken up by the surface enamel. After eruption, the enamel continues to take up fluoride from its oral environment leading to its profound topical effects (Kidd 2005). What is tooth decay? It is important to consider the causes of tooth decay and how fluoride can be used to reverse the carious process. Dental Caries is a multifactorial disease caused by the action of acidogenic and aciduric bacteria (Streptococcus Mutans and Lactobacilli ({{32 Featherstone,J.D. 2008}}) on fermentable carbohydrates such as sucrose. Salivary glycoproteins form a pellicle on the tooth to which these bacteria attach to forming a pathogenic biofilm and over time, acid demineralisation and proteolytic destruction of the organic component of the enamel and dentine takes place (Young, Kutsch Whitehouse 2009). Dental Caries can be classified in several ways According to location-Caries may be restricted to pits and fissures but may also progress to expose the pulp. Restorative status of the tooth- Primary caries occurs on previously unrestored teeth whereas secondary caries occurs at margins of restorations {{52 Kidd,Edwina A.M. 2005}}. Secondary caries is caused by local factors that are involved in the formation of cariogenic plaque. Most secondary carious lesions develop at the gingival margins of restorations primarily in areas of stagnation areas (Mjà ¶r, 1998). Large gaps between the restoration and the wall of the cavity preparation can create an environment that favours secondary caries formation (Mjà ¶r, 1998). Secondary caries is also known as recurrent caries. Caries can be arrested whereby a lesion which was previously active has now stopped progressing. Fluoride: Mode of Action Fig 1: Demineralisation Process and the role of fluoride (Cury, Tenuta 2008) Figure one shows how sugars such as sucrose, glucose and fructose are converted to acids in the plaque biofilm. When the pH decreases below 5.5 (critical pH of enamel), the saliva is no longer supersaturated with calcium and phosphate. Therefore, demineralisation occurs. However, in the presence of fluoride and if the pH is higher than 4.5, hydroxyapatite is converted to fluorapatite which has a lower solubility. As a result, net demineralization is reduced and the dental hard tissues are more acid resistant. Tenuta and colleagues calculated that fluorapatite would not dissolve until the pH dropped below approximately 4.4. However, researchers have found that the effect of fluoride is not only due to the decreased solubility but also due to the effect of fluoride on the rates of demineralisation and remineralisation (Stoodley et al. 2008). In order to enter bacteria, fluoride must be combined with a hydrogen ion forming hydrogen fluoride (HF), which readily diffuses into the cell. Once inside the bacterial cell, the HF dissociates into fluoride and hydrogen ions. The fluoride inhibits intracellular bacterial enzymes such as enolase. As a result, less phosphoenolpyruvate and lactate are formed. The reduced lactate formation limits the ability of bacteria to cause caries. Similarly, the uptake of glucose is also reduced by fluoride {{63 Featherstone,J.D. September 2004}}. The fluoride concentration in saliva increases after brushing with a fluoride toothpaste. After three minutes, the concentration is 100 times greater than the baseline value (normally 0.03ppm or 1.6umol/l) {{65 Murray, J.J 1991}}. Two hours later, the concentration returns to normal. It is important to avoid rinsing out the mouth as the most profound effects of fluoride are within two hours of brushing. Fluoride is spread throughout the oral cavity and is stored in compartments on the tooth surface and the remaining pellicle (Cury, Tenuta 2008). Calcium Fluoride globules are formed and are reservoirs of fluoride, releasing it as the pH falls, thereby, reducing time spent in the demineralisation phase. The main effects of fluoride can be attributed to the maintenance of constant fluoride levels in the biofilm. Overall, fluoride has multiple ways of reducing caries. It is believed that the most important of these methods is the remineralisation concept {{40 Oganessian,E. 2007}}, which requires a constant flow of fluoride. Bacterial enzyme inhibition plays a supplementary role when the concentration of fluoride is high which is achieved by topical fluoride applications and toothpastes (Murray, Rugg-Gunn Jenkins 1991). Who is at risk of decay? There are certain groups in the population who are at risk of decay and therefore, would benefit from the use of fluoridated dentifrices. These include patients with: Xerostomia, which may have resulted from the radiotherapy to the head or neck leading to salivary gland exposure. This leads to a decrease in both the resting and stimulated salivary flow rates. Xerostomia is defined as the complete absence of saliva or hyposalivation. Hyposalivation leads to decreased levels of calcium, phosphate and hydrogen bicarbonate ions. As a result, there is a longer demineralisation phase Sjà ¶grens syndrome- this is clinically defined as at least two of kerataoconjuctivitis sicca, Xerostomia(dry mouth) and rheumatoid arthritis or another connective tissue disease {{62 Newbrun,E. 1996}} A high incidence of caries in their primary dentition Hypersensitivity Root caries Removable orthodontic appliances and partial dentures A poor diet and those who regularly snack on fermentable carbohydrates {{37 Evans,R.W. 2008}}. However, this risk has decreased due to better plaque control and increased fluoride exposure. Multiple restorations suggesting a high prevalence of caries Optimum fluoride concentration required for remineralisation Bjarnason and Finnbogason (1991) found that fluoride levels in dentifrices had no effect on the progression of enamel lesions detected radiographically. However, a higher fluoride concentration (1000ppm F-) led to reduction in caries initiation compared to a dentifrice with a lower fluoride concentration (250ppm F-) {{69 Bjarnason, S. 1991}}. It is ultimately difficult to decide the optimum fluoride concentration required for remineralisation as different areas of the mouth are more at risk of caries due to unique ecological factors. However, it was thought that lesion progression in enamel was slowed down only in patients with low caries activity whereas patients with high caries activity still experienced rapid progression (Hellwig, Lussi 2001). DMF Index The DMF index is a measure of caries activity in a population and changes in the DMF index can be used to highlight the protective effects of the fluoride toothpastes and varnishes (Kidd 2005). D: decayed teeth with untreated carious lesions M: missing teeth (extracted teeth) F: filled teeth DMFT denotes decayed, missing and filled teeth DMFS denotes decayed, missing and filled surfaces in permanent teeth and therefore, the number of surfaces attacked on each tooth are accounted for. There are similar indices for deciduous tooth, which are the defs and deft scores. The e represents extracted teeth to differentiate(Johansen et al. 1987) between natural loss of teeth through exfoliation. Burt in 1998 suggested that greater emphasis has to be placed on the assessment and early diagnosis of caries {{77 Burt, B.A. 1998}}. This has been backed up by cohort studies {{83 Johansen, E. 1987}} (Axelsson, Lindhe Nystrom 1991), which found that the use of preventive strategies (fluoride application) resulted in a substantial reduction in lesion development and progression. Fluoride varnishes What is fluoride varnish? Fluoride varnish was first developed in New York in 1968 by Heuser and Schmidt in the form of sodium fluoride and was marketed under the name Duraphat. The Duraphat varnish contains 22,600 parts per million of fluoride (ppm Fˆ°) as shown in figure 2. In the 1970s, there was a switch from sodium fluoride to difluorsilane which was marketed under the name Fluor Protector (7000ppm Fˆ°) in Germany {{42 Azarpazhooh,A. 2008}}. Fluoride Varnish Type of fluoride Fluoride Concentration(ppm) Fluoride Concentration(%) Duraphat Sodium Fluoride 22,600 2.26 Duraflor Sodium Fluoride 22,600 2.26 Fluor protector Difluorsilane 7,000 0.70 Fig 2: The table above shows the fluoride varnishes that are most commonly used. Other types of fluoride varnishes include: Fluoride Varnish Type of fluoride Fluoride Concentration(ppm) Fluoride Concentration (%) Lawefluor Sodium Fluoride 22,600 2.2 Bifluorid Sodium and Calcium Fluoride 56,300 5.6 Fig 3: The table above shows other fluoride varnishes which are available but are less commonly used {{24 Davies,G.M. 2008}}. Most fluoride varnishes contain fluoride in an alcoholic solution of natural tree resin. The main advantage of the varnish is that the resin base is very adherent to the tooth prolonging contact time between the fluoride and enamel {{26 Miller,E.K. et al 2008}}. Varnishes are easy to apply and relatively safe regardless of the high fluoride concentration as the amount of varnish applied to one child is only 0.5 ml on average (Ripa 1990; Petersson 1993). Varnishes are slow-releasing reservoirs of fluoride preventing immediate release of fluoride after application (Ogaard 1994). As a result, they are most effective at protecting against primary caries. The food and drug administration centre in America has not yet accepted fluoride varnish as an anti-caries agent but considered it as a liner/desensitising agent (Mason 2005). There is some debate as to the amount of fluoride taken up by the tooth surfaces. It was found that approximately half of the fluoride taken up by sound surfaces from Fluor Protector varnish was lost after 6 months suggesting that the large amount of fluoride taken up after one week does not bind permanently to enamel and that the effects of fluoride are more short term. There has also been a debate over whether fluoride varnish should be applied to wet or dry surfaces. Koch et al found that the fluoride uptake was much greater when the varnish was applied to dry tooth surfaces (Koch, Hakeberg Petersson 1988). Fluoride varnishes can be applied professionally up to two to four times a year. Marinho et al in 2002 investigated the effectiveness of fluoride varnish in preventing dental caries in children compared to a placebo or no treatment. Over 2700 systemically healthy children aged 16 or less received fluoride varnish containing 22,600ppm sodium fluoride. There was a large caries inhibiting effect on both permanent and deciduous dentition. However, the confidence intervals were relatively wide and the variation among the results was substantial. The success of the treatment may have been over estimated, as the results of the few trials may not have been representative. As a result, it is important to carry out more trials before a definite statement can be made of the effects of the fluoride varnish (Marinho 2002). In addition, more information is required on the scale of the fluoride effect and the adverse effects of fluoride. Effect on the DMFT/dmft Primary Dentition There was a 33% decrease in the decayed, missing and filled surfaces (Marinho 2002). A two year randomised clinical trial carried out on children with a mean age of 1.8 years, found that the application of fluoride varnish once, twice and three times a year reduced the mean dmfs by 53%, 58% and 93% respectively {{67 Davies,G.M. 2009}}. This highlights the importance of frequent varnish application. (Petersson, Twetman Pakhomov 1998)Petersson et al. in 1998 found a 19% and 25% reduction in the increment of approximal caries in children with a moderate or high caries risk respectively. This shows that children with a high caries risk benefit the most from the application of fluoride varnishes (Zimmer 2001). Ages 0-3 Weintraub and colleagues carried out a two year randomised controlled trial on 376 children aged between 6-44 months (Weintraub et al. 2006). The children were split into three groups: Those who received counselling Those who received counselling and the annual application of Duraphat Those who received counselling and the twice yearly application at six monthly intervals The number of lesions only increased in children who received counselling alone highlighting the protective effects of the varnish. Those children who received no varnish application were twice as likely of developing decay as those who received the annual application of fluoride. As the frequency of fluoride varnish application increased, the number of carious lesions decreased. One drawback of this trial was that simultaneous counselling and varnish application led to some ambiguity as to whether the effects were due to varnish application or counselling although fluoride application was seen to play a key role. Ages 3-6 According to the Cochrane Review, there was an overall 38% reduction in the DMFS/dmfs (Marinho 2002). A two year randomised study of 1,275 children in Canada aged between 6 months and 5 years found that twice-yearly application of Durafluor led to an 18.3% reduction in the dmfs increment (Lawrence et al. 2006). Mixed dentition There was on average a 46% decrease in dmfs. The fluoride varnish was an effective preventive measure for partially erupted permanent molars. Equally, patients who are insufficiently co-operative benefit from fluoride varnish application (Marinho 2002). Permanent dentition A randomised clinical trial used to examine the impact of fluoride varnish on the incidence of approximal caries, detected radiographically in 13 year olds over a three year period, found that the varnish applied monthly and twice a year reduced caries by 76% and 57% respectively again highlighting the importance of frequent fluoride application{{67 Davies,G.M. 2009}}. The caries reduction in permanent teeth shown in the Cochrane review of trials was similar to that achieved in a metaanalysis carried out by Helfenstein in 1994 when Duraphat was applied 2 times a year in children aged 9-15 years (Helfenstein, Steiner 1994). There was a 38% reduction in the caries. It is likely that most of the participants benefited from the use of a fluoridated dentifrice as the majority of the studies were carried out in Scandinavian countries between 1973 and 1987. However, as both the Cochrane review and the Helfenstien study were carried out involving a different selection criteria, it is debatab le as to whether the results from both these trials can be compared. In conclusion, application of fluoride varnish two to four times a year on both permanent and deciduous teeth is associated with a reduction in the caries increment (Marinho 2002). The effect of fluoride varnish according to different caries risks Mà ¶berg Skold carried out a trial which involved the application of fluoride varnish to approximal caries in adolescents living in different caries risk areas. The trial involved 758 students aged between 13 to16 years old. The large sample size meant that the results of this study were representative. This is because as the sample size increases, the variability of the results decreases. This means that the results have a greater statistical power and smaller confidence intervals. Fig 4: (Azarpazhooh, Main 2008) The figure above shows the groups which were chosen according to their caries risk and whether they had any fluoride in their tap water. Duraphat was applied to the approximal surfaces from the distal surface of the canines to the mesial surface of the second molars. Each group had different intervals of application shown in the figure below: Group No. of participants Frequency of Duraphat application One 190 Twice yearly in six-monthly intervals ( 6 times in 3 years) Two 186 Three times a year with a one week period each year(9 times in 3 years) Three 201 Eight times a year during school terms with one month intervals ( 24 times in 3 years) Four(Control) 181 No application Fig 5: (Azarpazhooh, Main 2008) The frequency of Duraphat application The results from this trial show that the biggest difference was between group one and the control group in high caries risk area (Gà ¶teborg). However, there was no significant difference between the groups regarding filled approximal lesions and approximal enamel lesions. There was a greater incidence of caries in the control group in comparison to the fluoride varnish groups in all risk areas highlighting the protective effects of the fluoride varnish (Mà ¶berg Skold et al. 2005). Overall, it was found that the school based monthly application of fluoride varnish is the best method of preventing approximal caries in areas of medium and high caries risk (Mà ¶berg Skold et al. 2005). School based prevention programmes A cluster randomised trial was carried out by M.C Hardman and colleagues involving 2,091 school children living in a non-fluoridated area. One group of students (1,025 students) received the twice-yearly application of Colgate Duraphat varnish whilst the other group (1,066 students) served as a control. This study found that the twice-yearly application of fluoride varnish did not lead to a reduction in caries in children living in the community {{43 Hardman,M.C. 2007}}. This is contrary to what was found by Marinho and colleagues. They found that the biannual application of Duraphat in a school-based programme provided a caries inhibition of 38% in children aged 9-15 years (Marinho 2002). The study carried out by M.C Hardman and colleagues did not prove to be conclusive as the level of consent in the community was low. Approximately 110 students were lost during the study. The control group had lower caries levels than anticipated and therefore, it was difficult to tell the true eff ect of fluoride. In addition, the application of varnish was carried out under sub-optimal conditions (teeth could not be cleaned prior to application and the consumption of food and drink after application could not be controlled), which could have resulted in less profound effects. In conclusion, it was found that this type of fluoride varnish intervention is not effective in the prevention of caries in the public {{43 Hardman,M.C. 2007}}. A similar study was carried in a small town located in the American Southwest on children attending a head start nursery using Duraflor as the varnish of choice. The trial began in the head start class of 2002. Duraflor was applied during well child visits every 9, 12, 15, 18, 24 and 30 months. The class of 2003 had no fluoride application and therefore, served as the control. The mean age was 4.40 years and approximately 168 males and 189 females took part. The results showed that children who received no treatment had a mean dmfs of 23.6 with a 95% confidence interval. Those children who received 1-3 treatments had a similar dmfs to those with no treatment. Only those children who had 4 to 5 treatments showed a reduction in dmfs again suggesting the importance of frequent application. However, this study was an observational study not a randomised study and therefore, the reliability of the results can be questioned. In addition, no attempt was made to determine whether the childre n who received four or more applications of fluoride varnish differed from the other children in terms of diet and oral hygiene history {{58 Holve,S. 2008}}.. The use of fluoride varnish in inhibiting secondary carious lesions As mentioned earlier, secondary caries forms at the margins of restorations. Larger amounts of fluoride varnish may be trapped in the gap formed between the restoration and the cavity wall. This may serve as a slow releasing reservoir of fluoride, which could also provide a physical barrier against wall dissolution. In a study carried out by M. Fontana in 1996, two experiments were carried out. Experiment one involved the application of Duraflor. Experiment two involved the application of Duraphat a year after the application of Duraflor. The effects of fluoride varnish on secondary caries remineralisation and lesion progression were measured. The varnish was applied to dry tooth surfaces and rinsing after fluoride application was prevented to enhance the remineralisation potential. The varnish was applied for 24 hours to prolong the contact time between the varnish and the tooth surface. The results from these two experiments showed that fluoride application slowed down lesion progression around both amalgam and composite restorations {{48 Fontana, M. 2002}}. The placebo varnish slowed down lesion progression to a lesser extent than the fluoride varnish suggesting that the effects may not only be attributed to the fluoride in the varnish. These results matched those in a previous study carried out by Hellwig et al. in 1993. They examined the effect of Duraphat varnish on artificially created primary carious lesions and found that fluoride varnish led to remineralisation in the outer layers of enamel {{78 Hellwig, E.K. 1993}}. This slowed down lesion progression. Seppa suggested in 1988 that the benefits of fluoride varnish were attributed to their ability to enhance remineralisation of primary caries rather than their ability to increase the fluoride content of the tooth surface. This is contrary to what was previously thought that the effects of topical fluoride were due to their ability to maintain high levels of fluoride on the surface of the tooth. Seppa also found that the efficacy of the fluoride varnishes was dependent on the number of applications rather than the concentration of fluoride {{79 Seppà ¤, L. 1988}}. This backs up the results found by Marinho et al that showed that the more frequent the applicati on, the lower the incidence of new caries or the greater the decrease in mean dmfs/DMFS. Fluoride toothpaste What is fluoride toothpaste? Fluoride toothpaste is the most widely used method of fluoride application in the population due to its ease of use. Fluoride toothpastes can be incorporated into community and school based prevention programmes. Most oral health care workers recommend brushing twice a day, once just before going to bed, as this is when saliva flow is at its lowest and once at another time of day{{68 Davies,R.M. 2003}}. They recommend spitting out the toothpaste after use rather than rinsing as this dilutes the fluoride concentration in the oral cavity as previously mentioned. The widespread use of fluoride toothpastes had made it more difficult to distinguish whether a reduction in caries is due to mechanical plaque removal or due to the incorporation of fluoride. Before the widespread use of fluoride toothpastes, the importance of fluoride was illustrated in a three-year study. This study involved two groups of children aged 9 to 11 years who had benefited from supervised brushing either with or without fluoride toothpaste. Both groups showed a reduction in plaque and gingivitis but a significant reduction in caries was only seen in the group which used fluoridated toothpastes (Davies et al. 2003). A typical toothpaste contains abrasives such as calcium carbonates, which help to remove surface debris, and stains on the tooth surface. Most toothpastes contain fluoride (added to toothpastes in the 1970s) to make the tooth more resistant to acid attack and is one of the most recognised agents in toothpastes. Stannous fluoride (also known as tin fluoride) was the first fluoride to be used due to its compatibility with the abrasive, calcium phosphate. Sodium fluoride could not be used at first as the calcium in the abrasive renders it ineffective and therefore, is not compatible. Sodium Monofluorophosphate was next used as it was compatible with the abrasives used with it. Sodium Fluoride could only be used when hydrated silica and sodium bicarbonate became the abrasive of choice. Studies have shown that the sodium bicarbonate-sodium fluoride combination lead to a caries reduction of one surface per child over two years (Murray, Rugg-Gunn Jenkins 1991). Fluorides have been shown to work better in combination with detergents such as sodium lauryl sulphates, which aid the remineralisation process and create foaming whilst brushing. Toothpastes contain humectants such as glycerol, which prevent the loss of water in the toothpaste. To provide taste, saccharin and other sweeteners are added. To stabilise the toothpaste, thickening agents such as seaweed colloids are included to ensure that the toothpaste stays on the toothbrush when it is applied. The use of fluoride toothpastes in clinical trials The Cochrane review of trials found that children who used fluoridated toothpaste had fewer decayed,missing and filled permanent teeth after three years. Brushing twice a day helps to increase the benefit of fluoride (Marinho et al. 2003 England). Researchers believe that the effects of fluoridated toothpastes are underestimated in two to three year trials due to the life long used of fluoride. They also found that the use of fluoride toothpastes in areas of fluoridated water increased the protective effects. The normal concentration of fluoride in toothpastes is between 1000 and 1100 parts per million (ppm Fˆ°). Toothpastes with higher fluoride concentrations (1500ppm) and lower fluoride concentrations (500ppm) are available in many countries. Toothpastes containing higher fluoride concentrations offer greater protection against caries (Stephen 1988; OMullane 1997). Since the 1940s, more than a 100 clinical trials have been carried out and by the late 1970s, the protective effects of fluoride toothpastes were greatly accepted. As a result, many clinical trials could not have a control, as the removal of fluoride toothpaste for the trial was considered unethical. Therefore, the effectiveness of different concentrations of fluoride toothpastes have not been investigated extensively in placebo-controlled trails. The guidelines of caries trials have since been changed in order to combat this problem, by increasing the sample size so that the measurement error could be reduced (Marinho et al. 2003 England). Children or adolescents aged sixteen or less were chosen to take part in the study carried out by Marinho et al. To assess the effect of the fluoride toothpaste, the caries increment was measured as a change in the value of the DMFS Index, in all permanent teeth erupted at the start and erupting over the course of the study. Evidence from this study suggested that the use of fluoride toothpastes leads to a 24% decrease in dmfs. The confidence intervals for this reduction were 21-28%. This means that 1.6 children need to brush with fluoride toothpaste to prevent one decayed, missing or filled tooth surface in a population where the caries increment is 2.6 DMFS per year. Where the caries increment was lower (1.1 DMFS per year), 3.7 children needed to use a fluoride toothpaste in order to avoid one decayed, missing or filled tooth surface(Marinho et al. 2003 England). There was also a substantial reduction in caries increment (37%) of deciduous teeth in a trial carried out on 2008 children aged 6 to 9 years. Another aim of the Cochrane review (Marinho et al. 2003 England) was to establish whether there was any relationship between the caries-preventive effects of fluoride toothpaste and the initial level of caries, previous exposure to fluoride and the frequency of fluoride toothpaste use on the prevented fraction. The prevented fraction (PF) is the proportion of disease occurrence in a population averted due to a protective risk factor or public health intervention (Gargiullo, Rothenberg Wilson 1995). The prevented fraction was measured as the diffe
