The Academic Development of Education Faculty: Looking Back, Looking Ahead

A 2003 study about the lives of retired leaders in teacher education reminds us of the significant role that others play in the academic development of professors of education. That study also reveals significant changes in the nature of our work as teacher educators. The authors stress the need for universities to pay greater attention to the academic development needs of beginning teacher educators. Although many research-based universities offer programs for beginning faculty, the focus appears to be on teaching effectiveness. The authors make the case that beginning professors of education are different from those of beginning faculty in other disciplines. An argument is made that many beginning education professors need less support in teaching and service and more in the area of research.En 2003, une étude portant sur la vie de chefs en formation des enseignants et maintenant à la retraite nous rappelle le rôle significatif que jouent les autres dans le développement académique des enseignants en pédagogie. L’étude fait également ressortir les changements importants dans la nature de notre travail comme formateurs d’enseignants. Les auteurs soulignent le besoin pour les universités de porter plus d’attention aux besoins en développement académique de ceux qui débutent comme formateurs d’enseignants. Bien que plusieurs universités orientées vers la recherche offrent des programmes pour les professeurs débutants, l’on semble s’y concentrer sur l’efficacité de l’enseignement. Les auteurs exposent leur point de vue selon lequel les professeurs en pédagogie qui débutent leur carrière ne sont pas comme les professeurs qui débutent dans d’autres disciplines. Ils maintiennent que plusieurs professeurs en pédagogie qui commencent leur carrière ont davantage besoin d’appui dans le domaine de la recherche et moins dans celui de l’enseignement

Classificação do atendimento pré-hospitalar pediátrico como instrumento para otimizar a alocação de recursos no atendimento do trauma na cidade de São Paulo, Brasil

PURPOSE: To evaluate the pediatric prehospital care in São Paulo, the databases from basic life support units (BLSU) and ALSU, and to propose a simple and effective method for evaluating trauma severity in children at the prehospital phase. METHODS: A single firemen headquarter coordinates all prehospital trauma care in São Paulo city. Two databases were analyzed for children from 0 to 18 years old between 1998 and 2001: one from the Basic Life Support Units (BLSU - firemen) and one from the Advanced Life Support Units (ALSU - doctor and firemen). During this period, advanced life support units provided medical reports from 604 victims, while firemen provided 12.761 reports (BLSU+ALSU). Pre-Hospital Pediatric Trauma Classification is based on physiological status, trauma mechanism and anatomic injuries suggesting high energy transfer. In order to evaluate the proposed classification, it was compared to the Glasgow Coma Score and to the Revised Trauma Score. RESULTS: There was a male predominance in both databases and the most common trauma mechanism was transport related, followed by falls. Mortality was 1.6% in basic life support units and 9.6% in ALSU. There was association among the proposed score, the Glasgow Coma Score and to the Revised Trauma Score (p<0.0001). CONCLUSION: Pre-Hospital Pediatric Trauma Classification is a simple and reliable method for assessment, triage and recruitment of pediatric trauma resources.OBJETIVO: Avaliar o atendimento pré-hospitalar de crianças e adolescentes em São Paulo, avaliar o banco de dados das Unidades de Suporte Básico (UR) e Avançado (USA) e propor um método simples e eficaz para a avaliação da gravidade do trauma pediátrico na fase pré-hospitalar. MÉTODOS: Uma única central do Corpo de Bombeiros (COBOM) coordena todo o atendimento pré-hospitalar em São Paulo. Dois bancos de dados foram analisados para crianças de 0 a 18 anos de idade, entre 1998 e 2001: um das Unidades de Suporte Básico de Vida (UR- bombeiros) e outra de Unidades de Suporte Avançado (USA - médico e bombeiros). Neste período, o Serviço de Atendimento Médico de Urgência do Estado de São Paulo (SAMU) forneceu relatórios médicos de 604 vítimas, enquanto os bombeiros forneceram relatórios de 12.761 vitimas (UR+USA). A classificação do trauma pré-hospitalar pediátrico é baseada na condição fisiológica, mecanismo de trauma e lesões anatômicas das vítimas. A classificação do trauma pré-hospitalar pediátrico foi comparada à Escala de Coma de Glasgow (GCS) e ao Escore de Trauma Revisado (RTS). RESULTADOS: Houve predominância do sexo masculino em ambos bancos de dados. O mecanismo de trauma mais freqüente foi relacionado a transporte, seguido de quedas. A mortalidade foi 1,6% nas Unidades Básicas e 9,6% no Suporte Avançado. Houve associação entre a classificação do trauma pré-hospitalar pediátrico, Escala de Coma de Glasgow (GCS) e ao Escore de Trauma Revisado (RTS) GCS e RTS (p<0,0001). CONCLUSÃO: A classificação do trauma pré-hospitalar pediátrico é um método simples e confiável para a avaliação, triagem e recrutamento de recursos para o atendimento pré-hospitalar do trauma pediátrico.Universidade Federal de São Paulo (UNIFESP) Department of SurgeryUNIFESP, Department of SurgerySciEL

Use of Motor Abundance in Young and Older Adults during Dual-Task Treadmill Walking

Contains fulltext : 110120.pdf (publisher's version ) (Open Access)Motor abundance allows individuals to perform any task reliably while being variable in movement's particulars. The study investigated age-related differences in this feature when young adults (YA) and older adults (OA) performed challenging tasks, namely treadmill walking alone and while performing a cognitive task. A goal function for treadmill walking was first defined, i.e., maintain constant speed at each step, which led to a goal equivalent manifold (GEM) containing all combinations of step time and step length that equally satisfied the function. Given the GEM, amounts of goal-equivalent and non-goal-equivalent variability were afterwards determined and used to define an index providing information about the set of effective motor solutions relative to the GEM. The set was limited in OA compared to YA in treadmill walking alone, indicating that OA made less flexible use of motor abundance than YA. However, this differentiation between YA and OA disappeared when concurrently performing the cognitive task. It is proposed that OA might have benefited from cognitive compensation

Detection of mitochondrial DNA heteroplasmy suggests a doubly uniparental inheritance pattern in the mussel Mytella charruana

The unusual type of mitochondrial DNA (mtDNA) transmission in which females pass on their mtDNA F to both sons and daughters, and males pass on their mtDNA M to their sons, is termed Doubly Uniparental Inheritance (DUI) and has been observed in several bivalve mollusk families, including the Mytilidae. The present study found mitochondrial heteroplasmy in Mytella charruana, a tropical estuarine mytilid, which is most likely due to the occurrence of DUI. Cytochrome oxidase c subunit I (COI) sequences provide evidence for the presence of mtDNA M in the gonad and adductor muscle of male M. charruana. Intraspecific COI mtDNA F and mtDNA M mitotype divergence (p-distances) in M. charruana ranged from 20.5% to 20.8%. COI phylogenetic trees suggest that mtDNA M arose before M. charruana, Perna perna and Mytella guyanensis split, though independently of the DUI event that occurred in the genera Mytilus and Brachidontes. The comparison of COI gene products of mtDNA M among M. charruana and other bivalves, including mytilids, has shown that they all have important differences, suggesting independent evolutionary changes in their male COI lineages.(Detecção de heteroplasmia no DNA mitocondrial sugere um padrão de herança dupla uniparental em mexilhões Mytella charruana). Um tipo de transmissão não usual de herança do DNA mitocondrial (mtDNA), na qual as fêmeas passam os seus mtDNA F aos filhos e às filhas e os machos passam os seus mtDNA M para os seus filhos machos, é conhecido por herança dupla-uniparental e tem sido observada em várias famílias de moluscos bivalves, incluindo a Mytilidae. O presente estudo mostrou a ocorrência de heteroplasmia mitocondrial em Mytella charruana, um mitilídeo estuarino tropical, provavelmente devido a herança dupla uniparental. Sequências da citocromo oxidase c subunidade I (COI) mostraram que o mtDNA M está presente nas gônadas e nos músculos adutores dos machos de M. charruana. As divergências intraespecíficas (distância-p) entre as sequências de COI dos mitótipos mitocondriais mtDNA F e mtDNA M em M. charruana variaram de 20.5% a 20.8%. As árvores filogenéticas baseadas em COI sugerem que o mtDNA M surgiu antes da separação das espécies M. charruana, Perna perna e Mytella guyanensis, independentemente do evento DUI que ocorreu nos gêneros Mytilus e Brachidontes. A comparação dos produtos do gene mtDNA M de M. charruana e de outros bivalves, incluindo mitilídeos, mostrou que eles têm importantes diferenças, sugerindo mudanças evolucionárias independentes em suas linhagens masculinas de COI

The effects of an extensive exercise programme on the progression of Mild Cognitive Impairment (MCI): study protocol for a randomised controlled trial

Background Exercise interventions to prevent dementia and delay cognitive decline have gained considerable attention in recent years. Human and animal studies have demonstrated that regular physical activity targets brain function by increasing cognitive reserve. There is also evidence of structural changes caused by exercise in preventing or delaying the genesis of neurodegeneration. Although initial studies indicate enhanced cognitive performance in patients with mild cognitive impairment (MCI) following an exercise intervention, little is known about the effect of an extensive, controlled and regular exercise regimen on the neuropathology of patients with MCI. This study aims to determine the effects of an extensive exercise programme on the progression of MCI. Methods/design This randomised controlled clinical intervention study will take place across three European sites. Seventy-five previously sedentary patients with a clinical diagnosis of MCI will be recruited at each site. Participants will be randomised to one of three groups. One group will receive a standardised 1-year extensive aerobic exercise intervention (3 units of 45 min/week). The second group will complete stretching and toning (non-aerobic) exercise (3 units of 45 min/week) and the third group will act as the control group. Change in all outcomes will be measured at baseline (T0), after six months (T1) and after 12 months (T2). The primary outcome, cognitive performance, will be determined by a neuropsychological test battery (CogState battery, Trail Making Test and Verbal fluency). Secondary outcomes include Montreal Cognitive Assessment (MoCA), cardiovascular fitness, physical activity, structural changes of the brain, quality of life measures and measures of frailty. Furthermore, outcome variables will be related to genetic variations on genes related to neurogenesis and epigenetic changes in these genes caused by the exercise intervention programme. Discussion The results will add new insights into the prevailing notion that exercise may slow the rate of cognitive decline in MCI

Suicide in Brazilian indigenous communities: clustering of cases in children and adolescents by household

OBJECTIVE: To estimate age and sex-specific suicide rates, compare suicide rates between indigenous communities, and quantify the frequency of intrafamilial suicide clustering. METHODS: We performed a retrospective cohort study involving 14,666 indigenous individuals in reservations in Dourados, state of Mato Grosso do Sul, Brazil, from 2003 through 2013 using national and local census. RESULTS: The overall suicide rate was 73.4 per 100,000 person-years. Adolescent males aged 15–19 and girls aged 10–14 had the highest rates for each sex at 289.3 (95%CI 187.5–391.2) and 85.3 (95%CI 34.9–135.7), respectively. Comparing the largest reservations, Bororo had a higher suicide rate than Jaguapiru (RR = 4.83, 95%CI 2.85–8.16) and had significantly lower socioeconomic indicators including income and access to electricity. Nine of 19 suicides among children under 15 occurred in household clusters. Compared with adult suicides, a greater proportion of child (OR = 5.12, 95%CI 1.89–13.86, p = 0.001) and adolescent (OR = 3.48, 95%CI 1.29–9.44, p = 0.017) suicides occurred within household clusters. CONCLUSIONS: High rates of suicide occur among children and adolescents in these indigenous reservations, particularly in poor communities. Nearly half of child suicides occur within household clusters. These findings underscore the need for broad public health interventions and focused mental health interventions in households following a suicide

Write, draw, show, and tell: a child-centred dual methodology to explore perceptions of out-of-school physical activity

Background Research to increase children’s physical activity and inform intervention design has, to date, largely underrepresented children’s voices. Further, research has been limited to singular qualitative methods that overlook children’s varied linguistic ability and interaction preference. The aim of this study was to use a novel combination of qualitative techniques to explore children’s current views, experiences and perceptions of out-of-school physical activity as well as offering formative opinion about future intervention design. Methods Write, draw, show and tell (WDST) groups were conducted with 35 children aged 10–11 years from 7 primary schools. Data were analysed through a deductive and inductive process, firstly using the Youth Physical Activity Promotion Model as a thematic framework, and then inductively to enable emergent themes to be further explored. Pen profiles were constructed representing key emergent themes. Results The WDST combination of qualitative techniques generated complimentary interconnected data which both confirmed and uncovered new insights into factors relevant to children’s out-of-school physical activity. Physical activity was most frequently associated with organised sports. Fun, enjoyment, competence, and physical activity provision were all important predictors of children’s out-of-school physical activity. Paradoxically, parents served as both significant enablers (i.e. encouragement) and barriers (i.e. restricting participation) to physical activity participation. Some of these key findings would have otherwise remained hidden when compared to more traditional singular methods based approaches. Conclusions Parents are in a unique position to promote health promoting behaviours serving as role models, physical activity gatekeepers and choice architects. Given the strong socialising effect parents have on children’s physical activity, family-based physical activity intervention may offer a promising alternative compared to traditional school-based approaches. Parents' qualitative input is important to supplement children’s voices and inform future family-based intervention design. The WDST method developed here is an inclusive, interactive and child-centred methodology which facilitates the exploration of a wide range of topics and enhances data credibility

Asthma and gender impact accumulation of T cell subtypes

<p>Abstract</p> <p>Background</p> <p>The "Th2 hypothesis for asthma" asserts that an increased ratio of Th2:Th1 cytokine production plays an important pathogenic role in asthma. Although widely embraced, the hypothesis has been challenged by various empirical observations and has been described as overly simplistic. We sought to establish whether CD3+CD28-mediated and antigen-independent accumulation of type 1 and type 2 T cells differs significantly between nonasthmatic and asthmatic populations.</p> <p>Methods</p> <p>An ex vivo system was used to characterize the regulation of IFN-γ-producing (type 1) and IL-13-producing (type 2) T cell accumulation in response to CD3+CD28 and IL-2 stimulation by flow cytometry.</p> <p>Results</p> <p>IL-13-producing T cells increased in greater numbers in response to antigen-independent stimulation in peripheral blood lymphocytes from female atopic asthmatic subjects compared with male asthmatics and both male and female atopic non-asthmatic subjects. IFN-γ⁺T cells increased in greater numbers in response to either antigen-independent or CD3+CD28-mediated stimulation in peripheral blood lymphocytes from atopic asthmatic subjects compared to non-asthmatic subjects, regardless of gender.</p> <p>Conclusions</p> <p>We demonstrate that T cells from asthmatics are programmed for increased accumulation of both type 2 and type 1 T cells. Gender had a profound effect on the regulation of type 2 T cells, thus providing a mechanism for the higher frequency of adult asthma in females.</p
