Bullying escolar: um fenômeno multifacetado
School bullying can involve children in different ways, making them play different roles, among them, victims, bullies and bully-victims. The aim of this study was to describe how bullying occurs in high social vulnerability schools of Florianópolis metropolitan area and the roles played by students in this phenomenon. Overall, 409 children and adolescents from the 3rd to 5th grades and of two public elementary schools aged 8-16 years (X = 11.14) participated in this study. As a tool, the Olweus Questionnaire adapted to the Brazilian population was used. For data analysis, descriptive statistics and inferential statistics were applied by the Mann Whitney and Kruskal Wallis tests. As for results, 29.8% of boys and 40.5% of girls reported being victims; 32.3% of boys and 24.6% of girls reported being bullies. Victims were the most willing to help a colleague who is suffering from bullying (X = 1.54; p> 0.001), even if they do not know the victims (X = 1.57; p> 0.004). Bullies are differentiated from the group that does not participate (X = 1.73) and the group of victims (X = 2.34), being those who felt less alone (x = 1.47; p> 0.001). It was concluded that the information obtained in this study is indispensable in the search for alternatives to reduce school bullying. The strengthening of relations between school and students and a better preparation of teachers and school staff are extremely necessary to try to minimize the effects of risk factors to which these children are exposed and consequently violence at school.O bullying escolar pode envolver crianças de diferentes
maneiras, fazendo com que essas assumam papéis diferenciados.
Dentre estes, têm-se vítimas, agressores e vítimas-agressoras. O
objetivo deste estudo foi descrever como ocorre o bullying em
escolas de alta vulnerabilidade social da Grande Florianópolis
e os papéis assumidos pelos alunos nesse fenômeno. Quanto ao
método, participaram 409 crianças e adolescentes do terceiro
ao quinto ano e da quarta à sexta série do ensino fundamental,
de duas escolas públicas municipais, com idades entre 8 e 16
anos (X=11,14). Como instrumento, utilizou-se o Questionário
de Olweus adaptado à população brasileira. Para a análise
dos dados, empregaram-se a estatística descritiva e estatística
inferencial por meio dos testes Mann Whitney e Kruskal Wallis.
Quanto aos resultados, 29,8% dos meninos e 40,5% das meninas
relataram terem sido vítimas; já 32,3% dos meninos e 24,6%
das meninas relataram terem sido agressores. As vítimas foram
as que se mostraram mais dispostas a ajudar como podem um
colega que esteja sofrendo agressão (X=1,54; p>0,001), mesmo
que não o conheçam (X=1,57; p>0,004). Em contrapartida,
os agressores se diferenciaram do grupo que não participa
(X=1,73) e do grupo das vítimas (X=2,34), sendo aqueles que
menos se sentiram sozinhos (X=1,47; p>0,001). Concluiu-se
que as informações obtidas neste estudo são indispensáveis
na busca de alternativas para redução do bullying escolar. O
fortalecimento das relações entre escola e alunos, e um maior
preparo dos professores e funcionários são extremamente
necessários para tentar minimizar os efeitos dos fatores de
risco a que essas crianças estão expostas e consequentemente a
violência na escola.CAPES - Proc. nº 0815/14-4CIEC - Centro de Investigação em Estudos da Criança, IE, UMinho (UI 317 da FCT)Projeto Estratégico da FCT: UID/CED/00317/201

Manganese in Gasoline
This report responds to a resolution that asked the American Medical Association (AMA) to take action to reduce potential health risks from the use of methylcyclopentadienyl manganese tricarbonyl (MMT) in gasoline. Information for this report was derived from a search of the MEDLINE database and references listed in pertinent articles, as well as through communications with medical and public health experts. Based on this information, the AMA Council on Scientific Affairs determined that there is insufficient scientific evidence to assess the public health impact of MMT use. While limited evidence indicates that general-population exposures to manganese from the use of MMT in gasoline are low, more research is needed to determine possible health effects from long-term, low-dose exposures to MMT and its combustion products. Until such data are available, educational and informational strategies should be developed to improve public awareness of the health and environmental issues surrounding MMT use

Core competencies for disaster medicine and public health
Effective preparedness, response, and recovery from disasters require a well-planned, integrated effort with experienced professionals who can apply specialized knowledge and skills in critical situations. While some professionals are trained for this, others may lack the critical knowledge and experience needed to effectively perform under stressful disaster conditions. A set of clear, concise, and precise training standards that may be used to ensure workforce competency in such situations has been developed. The competency set has been defined by a broad and diverse set of leaders in the field and like-minded professionals through a series of Web-based surveys and expert working group meetings. The results may provide a useful starting point for delineating expected competency levels of health professionals in disaster medicine and public health.Lauren Walsh, Italo Subbarao, Kristine Gebbie, Kenneth W.
