Alcohol Consumption and Anxiety Amongst College Students

Honorable Mention Winner “According to a national survey administered by the National Institute on Alcohol Abuse and Alcoholism (NIAAA 2020) and a survey conducted by the American Psychological Association (APA) anxiety is one of the top concerns regarding college students. (APA, 2013) This systematic review was done to determine if there is a relationship between alcohol consumption and anxiety in college students. A total of 26 articles published between the years 2010 and 2020 that were retrieved from Psycinfo met the inclusion criteria needed for the analysis. In looking at the relationship between anxiety and alcohol consumption, the mediators of gender, underlying issues and motives, social anxiety, and protective strategies were also evaluated. A majority of the articles reviewed, 16 out of 26 articles, supported a positive relationship between anxiety in college students and alcohol consumption. The current findings are important as the use of alcohol to cope with anxiety can be seen as a vicious cycle. Alcohol consumption is linked to more anxiety and can have severe physical and mental health consequences. Additional research is needed to see how anxiety and alcohol consumption in college students can affect interpersonal relationships as well as academic achievement.

Neurofeedback: reforço do ritmo sensoriomotor com montagem bipolar em jovens surfistas

Este estudo procurou explorar os efeitos do neurofeedback (NF) na otimização dodesempenho e no electroencefalograma quantitativo (qEEG) de jovens surfistas com idadescompreendidas entre os 10 e os 16 anos. Os participantes (N = 8) foram distribuídos deforma semi-aleatória em dois grupos equivalentes, um experimental (n = 5) cujo foireforçado o ritmo sensoriomotor (SMR, 12 - 15 Hz) e inibido teta (4 - 8 Hz) e beta alto(23 - 38 Hz) numa montagem bipolar C3-C4, e outro grupo de controlo que recebeu umtreino NF falso. Todos realizaram 12 sessões NF (2 por dia), assim como uma mediçãoEEG das bandas treinadas e uma prova de surf, ambas medidas antes e depois do NF.Devido ao tamanho reduzido da amostra, os resultados de comparação entre-grupos nãoindicaram diferenças significativas. Uma análise de casos indica que a maioria dosparticipantes tiveram um aumento de teta (menor diferença significativa: p = .002, d =0.75) e uma redução de beta alto (menor diferença significativa: p = .006, d = 0.65) frutodo NF, sugerindo uma melhoria na atenção, concentração e possível maior resistência àpressão competitiva. Este estudo também propõe uma nova fórmula de cálculo de ráciopara medir o efeito do NF nas bandas de frequência cerebrais e explora a metodologia deavaliação do desempenho no surf para futuras investigações naquele desporto

Development of an injectable composite for bone regeneration

With the development of minimally invasive surgical techniques, there is a growing interest in the research and development of injectable biomaterials especially for orthopedic applications. In a view to enhance the overall surgery benefits for the patient, the BIOSINJECT project aims at preparing a new generation of mineral-organic composites for bone regeneration exhibiting bioactivity, therapeutic activity and easiness of use to broaden the application domains of the actual bone mineral cements and propose an alternative strategy with regard to their poor resorbability, injectability difficulties and risk of infection. First, a physical-chemical study demonstrated the feasibility of self-setting injectable composites associating calcium carbonate-calcium phosphate cement and polysaccharides (tailor-made or commercial polymer) in the presence or not of an antibacterial agent within the composite formulation. Then, bone cell response and antimicrobial activity of the composite have been evaluated in vitro. Finally, in order to evaluate resorption rate and bone tissue response an animal study has been performed and the histological analysis is still in progress. These multidisciplinary and complementary studies led to promising results in a view of the industrial development of such composite for dental and orthopaedic applications

Vivre harmonieusement la discipline au CP

Professorat des écolesLa discipline et l’autorité tiennent une place prépondérante à l’école. En effet, elles s’inscrivent dans une relation pédagogique qui met en présence des enfants et un adulte, des élèves et un maître. Cette relation est loin d’être évidente. La question qui se pose alors est : comment faire pour que cette rencontre se déroule au mieux ? Ou encore, comment faire pour que la discipline en vigueur dans la classe soit synonyme de climat de travail paisible, à la fois pour les enfants et pour le maître ? De plus, étant donné que l’enfant de CP sort tout juste d’une école maternelle bien différente de celle qu’il découvre, quel est dans ces conditions le rôle précis du maître pour garantir ce climat
