Several studies have shown that there is a circadian modulation of explicit memory. This modulation can occur independently in each one of the mnemonic processes. The aim of this study was to evaluate the influence of time of training on short-term memory (STM) and long-term memory (LTM), using a recognition task. Moreover, a possible circadian modulation in retrieving was investigated when this process matched the acquisition hour (time stamp). The chronotype variable was also considered. Fifty-seven undergraduate students aging between 18 and 25 years (21,72 ± 2,14; 28 ♂) participated in this study. In the training phase (acquisition) the subjects heard a ten word list. Following this, they answered a recognition test to evaluate STM and one week later they answered a recognition test to evaluate LTM. In each chronotype, the subjects were divided in groups according to the training hour, part of them in the morning and the other in the afternoon. One week later some of the subjects in each group underwent LTM testing in the morning and others in the afternoon. When the subjects performances were analyzed together, independently of the chronotypes, a training hour effect was found in the LTM. The subjects trained in the afternoon had better performance. No time of day effect was found in the STM and in retrieving from the LTM. However, the morning types who were trained and tested in the same hour had a better performance in the LTM when compared to morning types trained and tested in different hours. This effect did not occur when the other chronotypes were analyzed. The circadian modulation seems to occur at least in two different ways. First, there is a circadian modulation in the acquisition/consolidation processes, with a better performance occuring in the afternoon. Secondly, there is a modulation in the retrieval mnemonic process, called time stamp phenomenon. This phenomenon, that occurred in the morning types, is showed for the first time in humans

Among a variety of learning conceptions, David Kolb´s Experiential Learning Theory proposes four different learning styles: diverging, characterized by orientation towards people and multi-perspective vision; assimilating, concerned with ideas and abstract concepts as well as theory formulation; converging, expert in dealing with technical tasks and problem solving; and accommodating, risk taker and good at getting things done. Interesting correlations have been pointed out between Kolb s learning styles, professional careers and genders. With respect to behaviors, specific cognitive skills and interests, sex differences are widely known, and explained by Evolutionary Psychology as the result of distinct selective pressures acting on each gender. The aim of this research was to assess adolescents learning styles and their relation with interests on school and career choices, analyzing possible gender differences. We distributed questionnaires to 221 senior high school students to research their preferences for school disciplines, professional activities and career choices. The Learning Style Inventory specified the learning style of each individual. Our results showed a high frequency of reflective styles, with predominance of females as diverging and males as assimilating. Concerning school and professional interests, there were correlations between styles oriented towards the abstract and technical interests. Moreover, females preferred disciplines related to languages and interpersonal activities while males preferred disciplines related to science and technical activities. There were more males in exact science and engineering careers, and more females in social science and applied social science. Correlations found between learning styles, school and professional interests corroborate Kolb´s propositions, and the findings about gender differences are supported by Evolutionary Psychology theories

The behavioral patterns follow to environmental changes, including area fidelity and individuals association patterns. Several techniques are used to record these behavioral patterns and the photo-identification has been suggested as a proper tool because of its various advantages. Based on this technique, this research verified, between August of 2005 and January of 2006, area fidelity and association patterns of Sotalia guianensis, at Distrito de Pipa s bays, Rio Grande do Norte State south coast. Besides, we measured the association patterns by using the Jaccard index or Half-Weight Index (HWI). According the observation, 22 individuals were not resighted, 11 were resighted, and 36 new individuals were recorded. Nowadays, 69 individuals are cataloged. The residency rate indicated heterogeneity on studied area permanence and the association patterns between photo-identified seem to be context-specific. In addiction, the comparison of associations between two different age classes showed some individuals more frequently interacting with immature individuals. We also observed fluidity on association patterns among our individuals. We suggest that S. guianensis population from Pipa shows plasticity

Parental investment increases the offspring s survival, though it decreases the opportunities for the parents to invest in a future progeny. In a broad sense, this investment is directed to one s own descendant, but in some cases, such as in adoption, resources are directed to non-relatives even in the absence of fitness benefits. Once there are many factors involved in adoption, this study investigated adopters candidates, aiming to analyze aspects considered by them for adopting, based on the Evolutionary Psychology s perspective. We analyzed the judicial proceedings´ files people who had been inlisted for adoption at the 2ª Childhood and Adolescence Law Court, Natal-RN. The adopter s motivations were classified into biological or social reasons. A relationship between adopters´ age and kind of motivation was found: requirements of young people were related to biological reasons while requirements of the old ones were related to social reasons. Fertility, mainly female requirer´s fertility, underlie this relationship, considering that women fertility is strongly influenced by age. The reasons to adopt were also related to the age of the desired child, once that people who wanted children older than 25 months alleged social reasons while those that wanted younger babies alleged biological reasons. There are lots of motives to adopt a child, but the phenomenon of adoption is broadly acknowledged by society as an act of love and the adoptive parents are often regarded as kind and generous people. It was observed, instead, that the reasons to adopt comes from the adopters themselves, related to the fulfillment of personal needs, such as increasing the family, carrying out mother/father role or having a company or someone to care form them in elderly age

Synchronism is the efetivation of the same behavior at the same time by two or more individuals. In cetology only from 2000 we verify an increasing of efforts for studies of synchronic behaviors. The synchronism in cetaceans was reported for a variety of contexts, including feeding, socializing, parental care, while resting, traveling and play, during afilliation, in sexual behaviour and possible while teaching. The synchronism in behavior is influenced by environmental factors and can be modified during stress situations such as the presence of boats. The aim of this study is to explore behavior synchronism presented by the estuarine dolphin (Sotalia guianensis) in Pipa, Rio Grande do Norte state, Northeastern Brazil. A total of 414 hours of observation during the year 2006, using scan sampling method, from a land based sighting was conducted. Analyses were conducted in four steps. Firstly, we determined the pattern of activity of the groups within the bay, testing for the influence of bay configuration before and after rains periods on the activity of animals. Analyses show that forage occurs more frequently after the rainy period, but there was no change in the number of individuals or spatial cohesions between them. Secondly, we analysed the influence of turism boat traffic on the behavior of animals. We verified no changes on the bahavior of animals during the presence of boats. Finally, we tested seven hypotheses regarding the ecological and social dynamics of synchronic behavior. Environmental aspects were considered the main influence for the synchronism, no influences of age, and more selective exihibition of synchronic breathing in feeding and social displays were observed during the study period

The Callitrichidae family presents cooperative breeding, where breeders and non breeders take care of the offspring. The aspects of care analyzed in this study were infant carrying, supervision, proximity and food transfer. Three sets of infants from two wild groups of Callithrix jacchus were studied in the environments of Caatinga (Assu group) and Atlantic Forest (Jundiaí group). The methods used in the study were instantaneous focal sampling (infant carrying, supervision and proximity) and continuous focal sampling (food transfer). In the two sets observed in Assu group, the father carried and transferred food to infants more than the rest of the group. The biggest contribution in supervision was from the father and from another adult male. The members that remained in proximity to the infants in both groups were the younger in the groups (juveniles and sub-adults). In the Jundiaí group, the father and the adult male helper of the group were the main caregivers; one of the sub-adult females was responsible for supervision of the infants. With the disappearance of the reproductive male and one of the sub-adults females in 3º month of infants life, the care was redistributed and the only adult male left in the group was the animal that contributed more in provisioning of the infant. In the Assu group, there were adult females in its composition which were involved in agonistic interactions with breeders and adult males, and seemed to influence their low participation in care. Food transfer initiates early in the development of the infants, as a way to encourage nutritional independence. Different types of food transfer (active food transfer, food steal, food steal attempt, passive food transfer and food handling) were observed in the study and frequency of each one varied with developmental phase and tolerance by the members. One relevant data of the study was the presence of active food transfer in Assu group, since in literature there are very few registers of this type of transfer for this species. It is important that groups from distinct environments and composition be studied for a better understanding of the dynamics of infants development

The stress responses can be parameters used in order to identify the welfare of animals. Behavior parameters can also be regarded as means to identify their relation to stressing situations. In this study, adult male and female poodle dogs, accustomed (group 1) or not (group 2) to the environment of a bath and grooming salon were analyzed through the plasmatic concentration of cortisol, cell counting of the immune system (total leukocytes and percentage of neutrophils and lymphocytes) and through observation of changes in behavior before and after the bath and grooming service. After arriving at the kennel, the dogs were taken to the bath and grooming facility, where they had their blood samples taken and were observed for ten minutes. The subsequent procedures consisted of the bath and grooming services and the collection of another blood samples. The research results were analyzed through non-parametric statistic tests and p < 0.05. Accustomed and non-accustomed dogs presented different hormonal and behavior responses: accustomed dogs presented an increasing of the cortisol level at the second blood samples collection, thus indicating stress towards the aforementioned procedures and presenting behavior responses which can be described as moderated stress. Non-accustomed dogs presented the same cortisol levels in both first and second samples suggesting that they were already reacting to the new environment. Dogs also shown behavioral responses which can be described as acute stress. Both male and female dogs showed similar immunological changes as well as different endocrine and behavioral profiles. Concerning aggression, this study demonstrates that biting the owner can be a predicting behavior of aggression during the bath and grooming service, male dogs were more aggressive than the female, and that males were more reactive to unknown caretaker. The results of this research propose that the familiarization of the animal with the bath and grooming environment and caretaker is important to the welfare of poodle dogs, especially to that of male dogs

The circadian behavior associated with the 24 hours light-dark (LD) cycle (T24) is due to a circadian clock , which in mammals is located in the hypothalamic suprachiasmatic nucleus (SCN). Under experimental conditions in which rats are espoused to a symmetric LD 22h cycle (T22) the two SCN regions, ventrolateral (vl) and dorsomedial (dm), can be functionally isolated, suggesting that each region regulates distinct physiological and behavioral components. The vl region regulates the locomotor activity and slow wave sleep (SWS) rhythms, while the dm region assures the body temperature and paradoxical sleep (PS) rhythms regulation. This research aimed to deepen the knowledge on the functional properties of circadian rhythmicity, specifically about the internal desynchronization process, and its consequences to locomotor activity and body temperature rhythms as well as to the sleep-wake cycle pattern in rats. We applied infrared motion sensors, implanted body temperature sensors and a telemetry system to record electrocorticogram (ECoG) and electromyogram (EMG) in two rat groups. The control group under 24h period LD cycle (T24: 12hL-12hD) to the baseline record and the experimental group under 22h period LD cycle (T22: 11hL- 11hD), in which is known to occur the uncoupling process of the circadian locomotor activity rhythm where the animals show two distinct locomotor activity rhythms: one synchronized to the external LD cycle, and another expressed in free running course, with period greater than 24h. As a result of 22h cycles, characteristic locomotor activity moment appear, that are coincidence moments (T22C) and non coincidence moments (T22NC) which were the main focus or our study. Our results show an increase in locomotor activity, especially in coincidence moments, and the inversion of locomotor activity, body temperature, and sleep-wake cycle patterns in non coincidence moments. We can also observe the increase in SWS and decrease in PS, both in coincidence and non coincidence moments. Probably the increases in locomotor activity as a way to promote the coupling between circadian oscillators generate an increased homeostatic pressure and thus increase SWS, promoting the decreasing in PS

A pesquisa considera a difusão de celulares e smartphones e as consequências deste fato em possibilidades para o ensino-aprendizagem. Aparatos de comunicação sempre estiveram ligados ao processo de ensino-aprendizagem. Entretanto, com o desenvolvimento mais intenso, nas últimas décadas, das Tecnologias de Informação e Comunicação (TIC), essa relação vem ganhando novos contornos. Surge a Internet, a evolução das máquinas computacionais e, recentemente, a explosão dos dispositivos móveis, fornecendo novos produtos e serviços convergentes. Nesse contexto, celulares e smartphones tem sido utilizados e recomendados para apoio e complemento do processo de ensino-aprendizagem: a chamada Aprendizagem Móvel. Esse ramo cresce devido à rápida expansão e barateamento dessas tecnologias na sociedade. Para verificar cientificamente essa relação foi realizada uma pesquisa de natureza qualitativa, do tipo exploratória, com dois projetos de Aprendizagem Móvel em andamento no Brasil, o Palma – Programa de Alfabetização na Língua Materna e o Escola Com Celular – ECC. Assim, a partir dos dados provenientes da pesquisa, identificamos alguns aspectos relacionados ao uso de celulares e smartphones para o processo de ensino-aprendizagem que contribuem na compreensão desse campo ainda em construção no Brasil. O uso desses dispositivos como suporte para processos de ensino-aprendizagem nos projetos estudados é delineado pelos aspectos tecnologia, dispositivo, público e contexto e novas tecnologias e Aprendizagem Móvel. O aspecto dispositivo desdobra-se em dimensões como disseminação, multifuncionalidade e acessibilidade que embasam os projetos, ainda favorece características apontadas como importantes para o processo de ensino-aprendizagem na atualidade, como mobilidade e portabilidade. Os projetos pesquisados demonstram potencial e metodologia adequada aos contextos para os quais foram criados e aplicados. Entretanto, a pesquisa indicou que ao mesmo tempo em que celulares e smartphones representam o ápice da convergência tecnológica e são considerados extremamente populares e acessíveis na sociedade contemporânea, com possibilidades concretas como nos projetos estudados, não conseguiram conquistar uma posição sólida como suporte para o ensino-aprendizagem. Tal indicação se deve, de acordo com o corpus, à carência de alguns fatores, como: fomento, as práticas se mostram extremamente dependentes da iniciativa pública ou privada para sua extensão e continuidade; sensibilização para o uso de tecnologias disponíveis, não consideram o aparelho dos próprios alunos e um planejamento que inclua, capacite e incentive o uso desses dispositivos. Além disso, a pesquisa também destaca a necessidade de uma visão crítica do uso e papel da tecnologia nesses processos.

O uso assertivo e eficiente das estratégias de aprendizagem depende, muitas vezes, da compreensão e consideração de aspectos psicológicos e motivacionais. O adequado emprego de estratégias de aprendizagem se reflete no desempenho acadêmico, no domínio de construtos e modelos e no amadurecimento crítico e científico. A presente tese defende que há uma relação entre as estratégias de aprendizagem autorregulada e as estratégias de aprendizagem autodeterminada predominantes em alunos de mestrado e doutorado em Contabilidade. O estudo se justifica, porquanto, porque além de inaugurar uma linha de pesquisa ainda inédita no contexto da Contabilidade Humana, seus resultados destacam um original entendimento da relação da aprendizagem com a regulação e a motivação pessoal. Tem como objetivo principal apresentar diagnóstico, dimensões e correlações das estratégias de aprendizagem autorregulada e aprendizagem autodeterminada de alunos de programas de pós-graduação stricto sensu em Contabilidade no Brasil. Participaram do survey 516 respondentes, sendo 383 mestrandos e 133 doutorandos. Foram aplicados dois instrumentos psicométricos: Self-Regulated Learning Strategies (SRLS) e Motivated Strategies for Learning Questionnaire (MSLQ). O modelo operacional de pesquisa delineou a formulação de oito hipóteses, sendo que a primeira delas sustenta a defesa da tese, enquanto as demais defendem a influência das variáveis idade, gênero, tipo de curso, estágio no curso, tipo de instituição de graduação, nota do curso atribuída pela Capes e graus de instrução dos pais nos níveis de Self-Regulated Learning (SRL) e Self-Determination Theory (SDT). A partir da análise multivariada dos dados, os resultados corroboraram a tese e a influência do gênero no nível de SRL. A metaconclusão desta tese ratifica os estudos referenciados, confirmando que a aprendizagem pode ser dominada e controlada pelo indivíduo, ao se adotar estratégias individuais de regulação e motivação. Uma importante contribuição desta pesquisa consiste em oferecer conclusões empíricas que podem ajudar docentes, discentes, pesquisadores, instituições de ensino e programas de pós-graduação a compreender mais sistematicamente os aspectos da aprendizagem autorregulada e da aprendizagem autodeterminada que caracterizam o aluno de Contabilidade. Limitações importantes deste estudo podem ser vistas como oportunidades para pesquisas futuras: a amostra envolve um público específico, a pesquisa survey pode apresentar vieses de método comum e a baixa participação de alunos de mestrado profissional. Estudos futuros poderão adotar outras estratégias metodológicas e/ou envolver amostras mais diversificadas ou em maior lastro temporal

O latim das inscrições romanas no território português não foi até à data alvo de um estudo individualizado. A única obra na qual o assunto foi tratado analisa o latim de toda a Península Ibérica e foi publicada há pouco mais de cem anos, estando desactualizada. As inscrições romanas do território português estão publicadas em diferentes obras. O Corpus Inscriptionum Latinarum continua a ser uma referência fundamental, mas, ao longo do século XX, foram publicados novos estudos, que actualizam leituras ou divulgam novas epígrafes. Desta forma, para caracterizar o latim das inscrições romanas no território português, é necessário constituir um corpus que inevitavelmente terá de incluir epígrafes provenientes de diversas publicações. A análise do latim das inscrições compreende aspectos fonéticos, morfológicos, sintácticos e lexicais. São seleccionados apenas aspectos relevantes para o estudo do texto epigráfico. O tratamento de cada um dos aspectos está dividido numa componente teórica, na qual se faz um balanço das conclusões da literatura científica, e numa componente prática, na qual se relatam os dados das inscrições do território português. O latim das inscrições do território português pode ser caracterizado como conservador, predominando nele o respeito pela correcção da língua. Para esta caracterização conservadora, contribui a presença de arcaísmos nas desinências nominais e verbais, alguns no século II. Por outro lado, não deixa de manifestar, à semelhança do latim de outras regiões, nomeadamente de Pompeios, algumas particularidades inovadoras, como a monotongação do ditongo ae ou a oscilação na grafia das vogais. Além destes aspectos, são ainda perceptíveis ténues diferenças internas, visto que há fenómenos documentados apenas em algumas regiões.

Nenhum outro realizador a trabalhar em Hollywood durante os anos 30 do século XX alcançou maior notoriedade do que Frank Capra. A sua biografia, tão parecida com as histórias de rags to riches, parece coexistir com as narrativas ilustradas em alguns dos seus filmes mais perenes. No entanto, apesar de todo este sucesso, a carreira de Frank Capra seria relativamente curta e, sobretudo, quase exclusivamente associada à década da Grande Depressão. A elaboração deste trabalho tem por objetivo articular a história pessoal de Frank Capra com as histórias da Grande Depressão, utilizando os filmes que dirigiu durante essa década e, neste processo, tornar aparentes alguns dos motivos para o sucesso do realizador durante os anos 30.

Esta dissertação consiste numa análise de quatro filmes de François Truffaut, nomeadamente La mariée était en noir (1968), La sirène du Mississipi (1969), L’histoire d’Adèle H. (1975) e La chambre verte (1978). O meu estudo centra-se nalgumas figuras pertencentes a sistemas de representação, que ocupam posições de relevo nas narrativas e na imagética destes filmes. Assim, considero o tratamento dado a fotografias, pinturas, desenhos ou esculturas no quadro maior da imagem fílmica, e atento na caracterização de certas personagens enquanto, elas mesmas, propiciadoras de uma reflexão acerca da imagem. Finalmente, procuro repensar o modo como, associando esse trabalho sobre objectos representativos a um pensamento sobre a morte, Truffaut formula uma meditação sobre o cinema enquanto arte intimamente relacionada com a noção de fantasma.

A presente dissertação de Mestrado em Estudos Regionais e Locais aborda o papel do Centro de Informação Popular de Machico (CIPM), entre 25 de Abril de 1974 e 25 de Novembro de 1975. Este agrupamento, surgido logo após o 25 de Abril, constituiu uma associação revolucionária, contribuindo para a transformação sócio-económica e político-cultural de Machico, através da difusão dos ideais da Revolução do 25 de Abril e da dinamização da comunidade local e regional, à luz desses novos valores. O CIPM foi um promotor e organizador de várias intervenções, nomeadamente, na alteração da gestão municipal, na extinção da colonia, na melhoria das condições de vida de diversos sectores profissionais, como as bordadeiras, os trabalhadores das conservas, os baleeiros, os operários da construção civil e os trabalhadores da hotelaria, bem como desenvolveu um conjunto de actividades educativas e culturais. Esta investigação permitiu concluir que o CIPM foi um agente decisivo para a expansão dos ideais da Revolução dos Cravos, em Machico e na Madeira, apoiando a materialização de um grande número de mudanças e impulsionando a instauração da prática democrática, quer a nível local, quer a nível regional.
