Ciclo de política curricular do estado do Pará (2008-2012): a enunciação discursiva sobre relações “raciais”

O presente estudo analisa os enunciados discursivos do ciclo de Política curricular do Estado do Pará sobre as relações “raciais” no período de 2008 a 2012, a partir da abordagem do ciclo de políticas, proposto por Stephen Ball. Nesta análise, é focalizada a produção das políticas no contexto de influência, contexto de produção de textos políticos e contexto da prática. O referencial teórico-metodológico que subsidia a análise parte da Teoria sócio-histórica e dialógica da linguagem com base em Bakhtin (2010, 2011), abordagem do ciclo de políticas abalizado pelas teorizações de Ball et al (1992), para os estudos acerca Relações “Raciais” partimos dos conceitos de Guimarães (1999, 2002, 2008) e Coelho (2009) sobre raça. E, sobre as relações sociais estabelecidas no campo educacional, utilizamos as noções conceituais de campo e de habitus em Bourdieu (2008, 2009, 2010). O estudo é de abordagem qualitativa (FLICK, 2004). Utilizamos como fontes de coleta de dados documentos orais e escritos, dentre os quais destacamos: Artigos, Teses e Dissertações sobre Relações “Raciais” e Política Curricular realizado em duas bases de dados nacionais e uma internacional: a) ANPED (GT-21); b) site da CAPES/PPGE; c) Fundação Ford. Publicações: a) Política de Educação Básica do Estado do Pará, especialmente o eixo da Política Curricular; b) I Conferência Estadual de Educação: Diagnósticos, diretrizes, objetivos e metas aprovadas; c) Educação Básica no Pará: elementos para uma política educacional democrática e de qualidade Pará todos (vol I e II) e entrevista semiestruturada com quatorze agentes sociais que atuavam na SEDUC, USE e escolas da Rede Pública Estadual, os quais participaram da Política Curricular do Estado do Pará. Os dados foram analisados por meio da análise do processo enunciativo-discursivo com base em Bakhtin (2010, 2011). A partir da análise da enunciação discursiva do ciclo de política curricular do Estado do Pará sobre as relações “raciais” e da interpenetração dos discursos entre os contextos de influência, contexto de definição de textos políticos e contexto da prática os resultados do estudo revelam que os diferentes enunciados produzidos nos variados contextos são marcados pela hibridização de discursos, resultado de processos de recontextualização. Infere-se que a política curricular do Estado do Pará se apresenta em inter-relações entre múltiplos contextos no ciclo de políticas (BALL, et al, 1992). A despeito do caráter contínuo e não hierarquizado das políticas, da articulação macro e micropolíticas avançarem em relação às abordagens estadocêntricas e do processo de recontextualização política que ocorre no contexto da prática, o estudo conclui que a política curricular do Estado do Pará existe como uma política de Estado, existe como uma política educacional. No entanto, na exequibilidade dessa política de Estado e educacional na escola no tocante as relações “raciais”, ela não ocorre por conta da fragilização da competência cultural e teórica desse agente social que deve executá-la. A fragilização está na concretização dessa política no contexto da prática. Há um problema entre o que se projeta e o que se prática, o que ajuda a atribuir a realidade social a disseminação e ratificação do racismo e discriminação nos diferentes contextos que compõe a política de currículo.

The time course of aggressive behaviour in juvenile matrinxa Brycon amazonicus fed with dietary L-tryptophan supplementation

This study evaluated the influence of dietary L-tryptophan (TRP) supplementation on the time course of aggressive behaviour and on neuroendocrine and hormonal indicators in juvenile matrinxA Brycon amazonicus. Supplementation with TRP promoted a change in the fight pattern at the beginning of an interaction with an intruder, resulting in decreased aggressive behaviours during the first 20min. The decrease in aggression did not persist throughout the interaction but increased at 3 and 6h after the beginning of the fight. Monoamine levels in the hypothalamus were not influenced by TRP before or after the fight; however, the hypothalamic serotonin (5-HT) concentration and the 5-hydroxyindole-3-acetic acid (5HIAA):5-HT ratio were significantly correlated with the reduction in aggressive behaviour at the beginning of the fight. Cortisol was not altered by TRP before the fight. After the fight cortisol increased to higher levels in B. amazonicus fed with supplementary TRP. These results indicate that TRP supplementation alters the aggressive behaviour of B. amazonicus and that this effect is limited to the beginning of the fight, suggesting a transient effect of TRP on aggressive behaviour. This is the first study reporting the effects of TRP supplementation on the time course of aggressive interaction in fishes. (C) 2013 The Fisheries Society of the British Isles

Anxiety and depression in brazilian undergraduate students: the role of sociodemographic variables, undergraduate course characteristics and social skills

The prevalence of anxiety and depression disorders in undergraduate students is high and several variables can be influential. The aim is to verify the predictive value of social skills, sociodemographic variables, and course characteristics for depression and anxiety. A total of 1282 students of a public university, of both sexes and from different years and courses, participated in this study. Screening instruments for depression and anxiety were applied, as well as an instrument investigating social skills and a questionnaire covering socio demographic indicators and course characteristics. The data were analyzed using univariate analysis followed by multiple binary regression analysis in order to define the relevance of these depression and anxiety measures. The rates of anxiety and depression were 19.4% and 3.8%, respectively. The social skills and living situation were predictive of depression, with the social skills and course area (with higher prevalence for the exact and human sciences) remaining in the final model for anxiety. Such data have implications for psychological prevention and intervention with this population.

THE INFLUENCE OF CHILDHOOD ABUSE ON LONGITUDINAL COURSE OF RECOVERY IN PSYCHIATRIC REHABILITATION

Background: Empirical outcome studies have identified specific symptomatic, cognitive, emotional and functional sequelae of childhood abuse in people with severe mental illness (SMI). These findings illuminate the need for an integrated understanding of biological, psychological, environmental, and developmental aspects of SMI. Purpose: The purpose of the present study includes the following: 1) to examine reliability and validity of the comprehensive child abuse rating system in a sample of individuals with SMI, 2) to examine the influence of childhood abuse severity on recovery of psychotic symptoms, neurocognition and social-cognition, and social functioning in people with SMI during 12 months of inpatient psychiatric rehabilitation, and 3) to examine moderating effects of social cognition on the relationship between severity of different types of child abuse history and social functioning. Results: In Study I (N=171), the child abuse rating system produced reliable ratings and some subtypes of child abuse history were related to poorer premorbid functioning and cognition, higher overall psychiatric symptoms, and lower social functioning. In Study II (N=161), the longitudinal factor pattern invariance of the measures of social functioning, externality, and psychiatric symptoms were confirmed across 3 time points (e.g., at admission, at 6 months, and at 12 months). In addition, significant but varied linear relationships between subtypes of child abuse and each level of assessment of functioning were identified. In Study III (N=143), the results showed that higher baseline social inference, independent of history of child physical abuse (CPA), played a protective role in improvements in social functioning. High externality appeared to be counter-therapeutic for individuals with no history of CPA but protective for individuals with a more severe history of CPA. Conclusion: The child abuse rating system appears to provide reliable and valid assessment of subtypes of child abuse history of individuals with SMI. Considering the extreme heterogeneity in both SMI and child maltreatment, the current finding sheds light on providing individualized treatment and assessment planning for individuals with SMI and a history of childhood abuse.

African American and Teaching in Higher Education IS a Course on Race and Culture

Using theoretical applications, the authors present an overview of theories that highlight approaches for teaching culturally sensitive content, personal experiences as educator and colleague in a predominantly white college campus and strategies for addressing culturally insensitive experiences in and outside the classroom. Presenters focus on the recruitment and retention of people of color and stress the need for today's predominantly white institutions to become more knowledgeable, tolerant and sensitive about their environments in an effort to make them more accepting.

A TRAINING COURSE ON BIOETHICS FOR FAMILY HEALTH STRATEGY PROFESSIONALS IN SANTO ANDRE, SP

This case report presents the experience of a training course on bioethics for nurses and physicians of the Family Health Strategy in Santo Andre, SP. This study is based on problem-based learning and deliberative bioethics, and aimed at presenting the deliberation procedure as a means of handling ethical issues. Contents were addressed in a cross-section manner through five sequential activity sessions at two different moments of concentration with one dispersion interval. In the first moment of concentration, key concepts and deliberative bioethics contents were developed. The second involved deliberation sessions on moral conflicts, which were selected and prepared during the dispersion interval. Participants evaluated the deliberation as an appropriate instrument to deal with the ethical issues they are faced with. Problem-based learning was an effective educational strategy for continuing education in deliberative bioethics.

Time course involvement of matrix metalloproteinases in the vascular alterations of renovascular hypertension

Increased vascular matrix metalloproteinases (MMPs) levels play a role in late phases of hypertensive vascular remodeling. However, no previous study has examined the time course of MMPs in the various phases of two-kidney, one-clip hypertension (2K1C). We examined structural vascular changes, collagen and elastin content, vascular oxidative stress, and MMPs levels/activities during the development of 2K1C hypertension. Plasma angiotensin converting enzyme (ACE) activity was measured to assess renin-angiotensin system activation. Sham or 2K1C hypertensive rats were studied after 2, 4, 6, and 10 weeks of hypertension. Systolic blood pressure (SBP) was monitored weekly. Morphometry of structural changes in the aortic wall was studied in hematoxylin/eosin, orcein and picrosirius red sections. Aortic NADPH activity and superoxide production was evaluated. Aortic gelatinolytic activity was determined by in situ zymography, and MMP-2, MMP-14, and tissue inhibitor of MMPs (TIMP)-2 levels were determined by gelatin zymography, immunofluorescence and immunohistochemistry. 2K1C hypertension was associated with increased ACE activity, which decreased to normal after 10 weeks. We found increased aortic collagen and elastin content in the early phase of hypertension, which were associated with vascular hypertrophy, increased vascular MMP-2 and MMP-14 (but not TIMP-2) levels, and increased gelatinolytic activity, possibly as a result of increased vascular NADPH oxidase activity and oxidative stress. These results indicate that vascular remodeling of renovascular hypertension is an early process associated with early increases in MMPs activities, enhanced matrix deposition and oxidative stress. Using antioxidants or MMPs inhibitors in the early phase of hypertension may prevent the vascular alterations of hypertension. (C) 2012 Elsevier B.V. All rights reserved.

Time course of the hemodynamic responses to aortic depressor nerve stimulation in conscious spontaneously hypertensive rats

The time to reach the maximum response of arterial pressure, heart rate and vascular resistance (hindquarter and mesenteric) was measured in conscious male spontaneously hypertensive (SHR) and normotensive control rats (NCR; Wistar; 18-22 weeks) subjected to electrical stimulation of the aortic depressor nerve (ADN) under thiopental anesthesia. The parameters of stimulation were 1 mA intensity and 2 ms pulse length applied for 5 s, using frequencies of 10, 30, and 90 Hz. The time to reach the hemodynamic responses at different frequencies of ADN stimulation was similar for SHR (N = 15) and NCR (N = 14); hypotension = NCR (4194 +/- 336 to 3695 +/- 463 ms) vs SHR ( 3475 +/- 354 to 4494 +/- 300 ms); bradycardia = NCR (1618 +/- 152 to 1358 +/- 185 ms) vs SHR (1911 +/- 323 to 1852 +/- 431 ms), and the fall in hindquarter vascular resistance = NCR (6054 +/- 486 to 6550 +/- 847 ms) vs SHR (4849 +/- 918 to 4926 +/- 646 ms); mesenteric = NCR (5574 +/- 790 to 5752 +/- 539 ms) vs SHR (5638 +/- 648 to 6777 +/- 624 ms). In addition, ADN stimulation produced baroreflex responses characterized by a faster cardiac effect followed by a vascular effect, which together contributed to the decrease in arterial pressure. Therefore, the results indicate that there is no alteration in the conduction of the electrical impulse after the site of baroreceptor mechanical transduction in the baroreflex pathway (central and/or efferent) in conscious SHR compared to NCR.
