Nessa dissertação, baseada em uma perspectiva genealógica da história, realizo uma análise da psicologia escolar no Brasil, buscando delinear a inserção de suas práticas, em um momento específico da vida política do país, a ditadura militar, durante as conturbadas décadas de 60 e 70. Para tal estudo, foi necessário enfocar momentos históricos anteriores, percorrendo brevemente da Primeira República à Era Vargas. Fundamental à emergência da psicologia escolar preventiva, detive-me no cotidiano brasileiro durante a ditadura militar, enfatizando como o golpe gerou efeitos econômicos, políticos, sociais, afetivos, assim como possibilitou a pregnância de uma cultura psicológica, responsável pela explosão das práticas exercidas pelos profissionais psi, tendo como efeito a produção de subjetividades privatizadas e intimistas. Para retratar a psicologia escolar nesse período, utilizei como fonte primária seis livros sobre essa temática de autores brasileiros. Nesses livros, predominava uma abordagem preventiva, profilática da psicologia escolar, resultando em intervenções junto a alunos, professores e pais, a procura de potenciais desvios que pudessem atrapalhar o andamento desejado para os trabalhos escolares. Antecipando desvios e conflitos, controla-se e normatiza-se todo o espaço escolar. A psicologia, além de atentar para as patologias, engloba também o campo da normalidade, da vida cotidiana. Assim, no compasso dos ideais propagados pelo regime militar e pela emergência da privacidade como fim em si mesma, a psicologia escolar compactua com os modos de subjetivação intimistas e individualizantes.

A presente dissertação ensaia propõe a aplicação do perspectivismo ameríndio, conforme trabalhado na obra do antropólogo Viveiros de Castro, enquanto posição a partir da qual atuaria o criminólogo de tal forma a potencializar o reconhecimento da alteridade na relação entre produção de saber e a figura do criminalizado ou criminalizável. Para tal, utiliza a criminalização do funk proibidão através de uma série de procedimentos legais como material primário sobre o qual se realiza este movimento. O texto se divide em três momentos principais. Primeiro, a apresentação desta chave de leitura como possível para o pensamento criminológico. Segundo, aponta de que forma os atores do sistema penal não realizam uma leitura do funk proibidão que reconheça sua alteridade para este fim, a análise do discurso é utilizada. Terceiro, propõe-se uma outra leitura do funk proibidão informada pela posição perspectivista que se mostra contrastante com aquela realizada pelo sistema penal.

Esta pesquisa tem o objetivo de analisar o discurso de jogadores de futebol em atividade que emergiram socialmente mediante a prática profissional desse esporte para tentar identificar se há relação entre suas atitudes, suas dificuldades de adaptação ao exterior e o fato de serem oriundos de famílias com baixa renda. O estudo surgiu a partir da observação de reportagens dos meios de comunicação em que figuravam constantes aparições de jogadores reconhecidos socialmente não só pela fama e pelo sucesso dentro do futebol, mas também por alguns de seus comportamentos dentro e fora de campo. Como fundamentação teórica buscou-se principalmente contribuições de Edgar Morin, que apresenta o conceito de cultura de massa dentro do qual se inserem os chamados heróis modernos. O autor afirma que os jogadores de futebol bem-sucedidos figuram nessa categoria e discute a promoção dessas novas vedetes a partir das constantes informações midiáticas sobre suas rotinas. No que tange às teorias relativas ao esporte, e mais especificamente ao futebol, fundamentou-se o estudo a partir dos pensamentos de Mário Rodrigues Filho, que apresenta a ascensão do negro e do pobre no futebol brasileiro, esporte de origem branca e elitista. O esporte é, portanto, estudado sob uma perspectiva sociocultural com importante influência no Brasil e no mundo, sobretudo por meio do futebol. A metodologia utilizada foi a técnica de análise documental de conteúdo, optou-se pela interpretação de reportagens da fonte primária revista Placar. Como recorte, foram escolhidas as edições lançadas entre janeiro de 2009 e dezembro de 2011, configurando um total de trinta edições em três anos. A partir do levantamento das revistas citadas, foram selecionadas, ao final de toda a análise, 19 entrevistas de jogadores de futebol profissional divididas nas seguintes categorias: (i) ascensão social; (ii) questão financeira; (iii) mau comportamento dentro e fora de campo; (iv) bom comportamento dentro e fora de campo; (v) volta ao futebol brasileiro; (vi) saudade do Brasil; (vii) sonho a ser realizado. A análise de dados foi realizada à luz do referencial teórico apresentado no trabalho relacionando a fala dos jogadores com os pensamentos dos autores. Nota-se através da análise que não existe qualquer relação entre o comportamento dos jogadores de futebol entrevistados pela revista placar e o fato de eles serem oriundos de famílias humildes e que suas dificuldades de adaptação ao exterior estão relacionadas à falta de uma preparação física completa.

The diversity and evolution of bitter taste perception in mammals is not well understood. Recent discoveries of bitter taste receptor (T2R) genes provide an opportunity for a genetic approach to this question. We here report the identification of 10 and 30 putative T2R genes from the draft human and mouse genome sequences, respectively, in addition to the 23 and 6 previously known T2R genes from the two species. A phylogenetic analysis of the T2R genes suggests that they can be classified into three main groups, which are designated A, B, and C. Interestingly, while the one-to-one gene orthology between the human and mouse is common to group B and C genes, group A genes show a pattern of species- or lineage-specific duplication. It is possible that group B and C genes are necessary for detecting bitter tastants common to both humans and mice, whereas group A genes are used for species-specific bitter tastants. The analysis also reveals that phylogenetically closely related T2R genes are close in their chromosomal locations, demonstrating tandem gene duplication as the primary source of new T2Rs. For closely related paralogous genes, a rate of nonsynonymous nucleotide substitution significantly higher than the rate of synonymous substitution was observed in the extracellular regions of T2Rs, which are presumably involved in tastant-binding. This suggests the role of positive selection in the diversification of newly duplicated T2R genes. Because many natural poisonous substances are bitter, we conjecture that the mammalian T2R genes are under diversifying selection for the ability to recognize a diverse array of poisons that the organisms may encounter in exploring new habitats and diets.

本文主要研究了具有己酸乙酯酯化活性的真菌菌株的筛选和发酵条件优化。从大曲和糟醅样品中分离纯化获得79株产生透明圈的丝状真菌,菌落形态初步识别结果显示分离菌株包括红曲霉属、根霉属及曲霉属等菌株。其中菌株EM-56酯化酶活力最强,发酵获得的粗酶制剂酶活为172.36 u。根据显微形态、菌落形态及生理生化特征,初步鉴定该菌株为曲霉科红曲霉属紫色红曲霉(Monascus purpureus)。 在此基础上重点研究了菌株EM-56在不同培养基成分及不同培养条件下的产酶情况,确定了最佳培养基和培养条件。通过单因素实验确定在基础培养基中添加最佳碳源为葡萄糖,最佳氮源为蛋白胨。正交优化实验结果确定了最佳培养基组成:以麸皮为基础培养基,添加葡萄糖 2%,蛋白胨 0.3 %,KH2PO4.3H2O 0.05 %,MgSO4.7H2O 0.06 %。菌株EM-56在上述培养基中的最佳发酵条件为:初始pH 5.5,发酵温度为35°C,发酵时间7d,种龄48h,接种量8%,装瓶量50g / 瓶(500mL)。在最佳培养基和发酵条件下,菌株EM-56发酵获得的粗酶制剂酶活达到241.56 u,比优化前提高了40.15%。 In this paper, the research focuses on the selection of fungus with esterifying activity and optimization of fermentation conditions. We isolated 79 strains which had transparent zones from Daqu and fermented grains. The isolated strains contained Monascus、Rhizopus and Aspergillus through primary morphology analysis. The strain of EM-56 which produces strongest esterase was selected. The enzyme activity reached 172.36u. According to related literature, EM-56 was identified as Monascus purpureus through morphology analysis and biochemical determination. We also studied the effects of different medium and fermentation conditions on the esterase production of strain EM-56. The optimal medium and fermentation conditions were determined. Single factor experiment result shows that the optimal carbon source added is glucose and the optimal nitrogen source added is peptone. The optimal fermentation medium determined by orthogonal optimization test is as follows: wheat bran as substrate, glucose 2%, peptone 0.3%, KH2PO4.3H2O 0.05%,MgSO4.7H2O 0.06%. The optimal fermentation conditions are: initial pH 5.5, cultural temperature 35°C, cultural time 7d, seed age 48h, inoculation 8%, medium mass 50g / flask(500mL). The esterse activity of EM-56 cultivated in the optimal medium and fermentation conditions reached 241.56u and increased by 40.15% compared with the original activity.

The phase coherence of supercontinuum generation in microstructure fiber is quantified by performing a Young's type interference experiment between independently generated supercontinua from two separate fiber segments. Analysis of the resulting interferogram yields the wavelength dependence of the magnitude of the mutual degree of coherence, and a comparison of experimental results with numerical simulations suggests that the primary source of coherence degradation is the technical noise-induced fluctuations in the injected peak power. © 2003 Optical Society of America.

Kinestatin, isolated from the skin of the Chinese toad, Bombina maxima, was the first bradykinin B2 receptor antagonist identified in amphibians. Molecular cloning established that it is co-encoded with the bradykinin-related peptide, maximakinin, within one of several skin kininogens. To examine other species within the genus Bombina for the presence of structural homologues of kinestatin, we subjected skin secretion of the toad, Bombina orientalis, to HPLC fractionation with subsequent bioassay of fractions for antagonism of bradykinin activity using an isolated rat tail artery smooth muscle preparation. A single fraction was located that inhibited bradykinin-induced relaxation of rat arterial smooth muscle and MALDI-TOF analysis of this fraction revealed that it contained a single peptide of molecular mass 3198.5 Da. Further primary structural analysis of this peptide showed that it was a 28-mer with an N-terminal Asp (D) residue and a C-terminal Val (V) residue that was amidated. The peptide was named DV-28 amide in accordance with these primary structural attributes. Synthetic DV-28 amide replicated the observed bradykinin antagonistic effect within the smooth muscle bioassay in a dose-dependent manner. In addition, it was observed to inhibit the proliferation of human microvessel endothelial cells (HMECs) as assessed by MTT assay. Bioinformatic analysis revealed that DV-28 amide was, like kinestatin, co-encoded with a bradykinin receptor agonist on one of two skin kininogens identified in B. orientalis. DV-28 amide thus represents a novel class of bradykinin antagonist from skin secretions of bombinid toads that appear to be a rich source of such novel peptides.

Background and aims: In 1989 a number of registers in Europe began recording new cases of type 1 diabetes diagnosed in children aged under 15 years using a common protocol. Trends in incidence rate during the 20 year period 1989-2008 are described.
Materials and methods: All registers operate in geographically defined regions and are based on a clinical diagnosis. When possible, completeness of registration in each register is assessed using capture-recapture methodology by identifying primary and secondary sources of ascertainment. The completeness estimate is obtained by identifying the numbers of cases identified by the primary source only, by the secondary source only and by both the primary and the secondary sources.
Results: Other registers have joined the Group since 1989, and 21 registers in 15 countries continue to submit registration data. In the first five years (1989-93) incidence rates varied from 3.2 per 100,000 in the Former Yugoslav Republic of Macedonia to 25.8 per 100,000 in the Stockholm area of Sweden. In the last five years (2004-2008) these same two registers again had the lowest and highest incidence, but rates had increased to 5.8 per 100,000 and 36.6 per 100,000, respectively. During the 20 year period all but two of the 21 registers showed statistically significant rates of increase (median rate of increase 4% per annum), and similar figures were obtained when this median rate of increase was estimated for the first half of the period (1989-98) and for the second half (1999-2008) . However, rates of increase differed significantly between the first half and the second half of the period for eight of the 17 registers with adequate coverage of both periods; four registers showing significantly higher rates of increase in the first half and four significantly higher rates in the second half.
Conclusion: The childhood type 1 diabetes incidence rate continues to rise across Europe by approximately 4% per annum, but the increase within a register is not necessarily uniform with periods of less rapid and more rapid increase in incidence occurring in some registers. This pattern of change suggests that important risk exposures differ over time in different European countries. Further time trend analysis and comparison of the patterns in defined regions are warranted.

O Neem (Azadirachta indica) é uma árvore indiana conhecida pela atividade pesticida e por várias atividades farmacológicas. De entre os vários compostos já isolados e estudados, a Azadiractina (AZA) foi identificada como o principal composto bioativo desta planta. Este composto apresenta uma grande diversidade de localizações nesta planta, porém assume a sua máxima concentração ao nível das sementes, porção que se apresenta também como a principal fonte de obtenção do óleo de Neem. O óleo apresenta-se como a porção menos estudada do Neem, quer ao nível do seu teor em AZA, quer ao nível das suas propriedades, nomeadamente antimicrobianas. Neste sentido, os objetivos primordiais deste estudo foram o doseamento da Azadiractina e a avaliação da atividade antimicrobiana em produtos contendo óleo de Neem. Um método analítico rápido, sensível e seletivo utilizando HPLC-UV foi desenvolvido para a identificação e quantificação da Azadiractina-A (AZA-A) e 3-tigloylazadirachtol (AZA-B) em diferentes amostras de óleo de Neem. O teor de AZA-A, B e A+B determinado nas amostras de óleo de Neem apresentou valores entre 58,53-843,42 mg/kg, 12,52-800,223 mg/kg e 104,20-1642,17 mg/kg, respetivamente. Na generalidade, os valores obtidos foram inferiores aos descritos na literatura. A partir dos resultados obtidos, verificou-se ainda que o teor destes compostos não é similar em todas as amostras, sendo este condicionado pela qualidade das sementes que deram origem ao óleo e pelo processo extrativo utilizado. Para além disso, foi possível inferir que duas das amostras testadas teriam qualidade inferior, dados os teores reduzidos de AZA que apresentavam. As diferentes amostras de óleo de Neem, bem como formulações comerciais contendo óleo de Neem, foram testadas em 14 microrganismos de forma a avaliar o seu potencial antimicrobiano. Após a análise, verificou-se atividade antimicrobiana de todas as amostras sobre todos os microrganismos testados, observando-se atividade tanto em bactérias Gram+ como Gram-. Os resultados alcançados mostraram que o óleo de Neem e as formulações comerciais contendo óleo de Neem têm um potencial antimicrobiano interessante, principalmente sobre bactérias comuns em patologias da pele. Para além disso, foi possível comprovar que, no caso do óleo de Neem, a AZA não será a principal responsável por esta atividade. Por outro lado, verificou-se que a atividade antimicrobiana das formulações comerciais não se deverá exclusivamente à presença do óleo de Neem, Doseamento da Azadiractina e avaliação da atividade antimicrobiana em produtos contendo óleo de Neem X uma vez que os valores dos halos de inibição obtidos com as formulações tenderam a ser superiores aos verificados apenas com o óleo, além de que os valores de inibição mais elevados foram observados para as formulações contendo menor percentagem de óleo de Neem incorporado. Em suma, os resultados alcançados para os diferentes produtos analisados são promissores e, na sua maioria, convergem com o que está descrito na literatura. No entanto, apesar destes resultados serem um grande contributo, mais estudos são necessários e importantes para conhecer melhor os produtos analisados e assim poder tirar o maior proveito deles.

The purpose of this qualitative study was to understand the relationships between creativity and the working artist/teacher employed by an art college. The topic emerged from my job as an instructor at The Ontario College of Art which was used as the primary data resource and provided the highest caliber of professionals to chose from. Existent data were used to facilitate the study generated by the research of Cawelti, Rappaport, and Wood (1992). The data were generated by a group of 5 faculty members from The University of Northern Iowa, recognized for their expertise in the arts (a painter, a poet, a sculptor, a novelist, and a photographer). They were asked to respond to the following statement: "In as much detail as you like, list the things that you did, thought, or felt the last time you created an artistic product. II Cawelti, Rappaport, and Wood (1992) produced three models of the creative process, each building on the previous, with the resultant third,being in my opinion, an excellent illustration (text/visual) of the creative process. Model three (Appendix D) presented a "multi-dimensional view of the creative process: time, space, observatility, and consciousnessll (p. 90). Model three utilized a visual mapping device along the bottom of the page linked to text segments above. Both the visual and the text were interrelated so that they harmonized into a comprehensive "picture." The parti'cipants of this qualitative study were asked to consider model three from their professional perspective as artist/teachers. The interpretive sciences directed the methodology. The hermeneutic circle of continuous reflection from the whole to the part and back to the whole was an important aspect of the data analyses. Four members of the Foundation Department at The Ontario College of Art were the key participants. A series of conversational interviews was the primary source of data collection, this was augmented by observation, fie,ldnotes, and follow up telephone interviews. Transcripts of interviews were returned to participants for reflection and the telephone was used to discuss any additional -points raised. Analysis consisted of coding and organizing data according to emerging themes. These themes formed the basis for the narrative stories. The text of the narrative stories were given back to each participant for further comment. Revisions were made until both the researcher and the participants felt that the stories reflected reality. The resultant whole was critiqued from the researcher's perspective. The significance of this study was discussed as it pertains to the working artist/teacher and areas in need of further study are pointed out.

This study examined how the athletic career of Roderick R. McLennan contributed to the popularization and subsequent development of Caledonian games in Ontario during the latter nineteenth century. Initially, the development of Caledonian games during the 1800s was examined to provide a contextual framework for McLennan's career. This investigation revealed that the games emerged from rural athletic events at pioneer working bees in the first quarter of the nineteenth century to regional sporting events by the mid-1800s, and finally into annual federated Caledonian games in 1870. Noteworthy primary source material for this chapter included the John MacGillivray Papers at the National Archives of Canada, the Scottish American Journal (NY) and the files retained by the Glengarry Sport Hall of Fame in Maxville, Ontario. Following the investigation of Caledonian games, McLennan's early athletic career was studied. Analysis of the Roderick and Farquhar McLennan Papers at the Archives of Ontario and the newspapers from the period revealed that McLennan rose to popularity in 1865 through a "Championship of the World" hammer throwing match in Cornwall and two "Starring Tours". The next chapter examined the height of McLennan's career through an investigation of the Roderick McLennan versus Donald Dinnie rivalry of the early .. n 1870s. It was detennined that the rivalry between McLennan and Dinnie, the champion athlete of Highland games in Scotland, was a popular attraction and had an impact on the Toronto and Montreal games of 1870 and the Toronto games of 1872. Finally, the athletic records established by McLennan during the 1860s and 1870s were investigated. These records were examined through the context of a media controversy over McLennan's feats that developed in the early 1880s between two newspapers. This controversy erupted between the Toronto Mail and the Spirit of the Times. Caledonian games in Canada have only been briefly examined and a thorough examination of prominent Canadian figures in this context has yet to be undertaken. This study unearths a prominent Canadian athlete of Scottish decent and details his involvement in the Caledonian games of nineteenth century Ontario.

This qualitative investigation explored the professional experiences of 3 Ontario teachers who have mobility challenges. The study’s participants (2 male and 1 female) were Ontario teachers who have permanent physical disabilities that challenge their means of mobility. Each participant has an Ontario Certified Teaching License and has either taught or is currently teaching in an Ontario school. My primary source of data collection was a semi-structured face-to-face interview with each participant. The focus of the interview was participant perspectives. Data analysis was accomplished in 3 phases. Data analysis generated 5 prominent themes of commonality among participants: (a) independence and sacrifice, (b) living with pain, (c) barriers and obstacles, (d) the importance of communication, and (e) professional benefits and personal rewards.

Dans son ouvrage Shell Shock Cinema, publié en 2009, Anton Kaes se distancie fortement du travail fondateur et classique de Siegfried Kracauer, From Caligari to Hitler, publiée en 1947, et portant sur le cinéma pendant la période de Weimar. Réfutant la thèse de Kracauer selon laquelle un inconscient collectif allemand annonce la montée du nazisme dans le cinéma de l’entre-deux-guerres, Kaes affirme au contraire que le shell shock, héritage de la Première Guerre mondiale, est l’un des moteurs du cinéma weimarien. Les travaux de Kaes s’inscrivent dans une historiographie en renouvellement qui, confrontant également la thèse de Kracauer, met désormais l’accent sur la Première Guerre mondiale, et non sur la Seconde Guerre mondiale, pour mieux comprendre et analyser le cinéma weimarien. Ce mémoire, tout en étudiant de façon détaillée l’historiographie du sujet, tend à approfondir et à réévaluer la thèse d’Anton Kaes en l’exposant à davantage de films représentant des traumatismes personnels, des traumatismes sociaux et des chocs post-traumatiques (CPT). Ces maux sont exacerbés par des tensions sociopolitiques – insurrection de janvier 1919, Traité de Versailles, occupation de la Ruhr, l’inflation de 1923-24, etc. – alimentant à la fois des représentations symboliques et concrètes d’expériences traumatisantes qui caractérisent l’ensemble du cinéma weimarien.

All intelligence relies on search --- for example, the search for an intelligent agent's next action. Search is only likely to succeed in resource-bounded agents if they have already been biased towards finding the right answer. In artificial agents, the primary source of bias is engineering. This dissertation describes an approach, Behavior-Oriented Design (BOD) for engineering complex agents. A complex agent is one that must arbitrate between potentially conflicting goals or behaviors. Behavior-oriented design builds on work in behavior-based and hybrid architectures for agents, and the object oriented approach to software engineering. The primary contributions of this dissertation are: 1.The BOD architecture: a modular architecture with each module providing specialized representations to facilitate learning. This includes one pre-specified module and representation for action selection or behavior arbitration. The specialized representation underlying BOD action selection is Parallel-rooted, Ordered, Slip-stack Hierarchical (POSH) reactive plans. 2.The BOD development process: an iterative process that alternately scales the agent's capabilities then optimizes the agent for simplicity, exploiting tradeoffs between the component representations. This ongoing process for controlling complexity not only provides bias for the behaving agent, but also facilitates its maintenance and extendibility. The secondary contributions of this dissertation include two implementations of POSH action selection, a procedure for identifying useful idioms in agent architectures and using them to distribute knowledge across agent paradigms, several examples of applying BOD idioms to established architectures, an analysis and comparison of the attributes and design trends of a large number of agent architectures, a comparison of biological (particularly mammalian) intelligence to artificial agent architectures, a novel model of primate transitive inference, and many other examples of BOD agents and BOD development.
