Pupils' Interaction with the Exhibits According to the Learning Behaviour Model

Science centres are one of the best opportunities for informal study of natural science. There are many advantages to learn in the science centres compared with the traditional methods: it is possible to motivate and supply visitors with the social experience, to improve people’s understandings and attitudes, thereby bringing on and attaching wider interest towards natural science. In the science centres, pupils show interest, enthusiasm, motivation, self-confidence, sensitiveness and also they are more open and eager to learn. Traditional school-classes however mostly do not favour these capabilities. This research presents the qualitative study in the science centre. Data was gathered from observations and interviews at Science North science centre in Canada. Pupils’ learning behaviours were studied at different exhibits in the science centre. Learning behaviours are classified as follows: labels reading, experimenting with the exhibits, observing others or exhibit, using guide, repeating the activity, positive emotional response, acknowledged relevance, seeking and sharing information. In this research, it became clear that in general pupils do not read labels; in most cases pupils do not use the guides help; pupils prefer exhibits that enable high level of interactivity; pupils display more learning behaviours at exhibits that enable a high level of interactivity.

As vozes do circo social

Este trabalho objetivou analisar como três projetos de circo social, na cidade do Rio de Janeiro, afetaram a vida de jovens que deles participaram. Tentou-se analisar, utilizando-se a metodologia da História Oral, suas mudanças de comportamento, atitudes e hábitos, assim como seus aprendizados e sucessos. Como resultados, percebemos que o circo social representa uma importante ferramenta pedagógica de transformação e realização de objetivos, devido as suas características peculiares.

Motivação para o cumprimento de normas de conduta social

O pressuposto que a motivação influi no comportamento e a internalização é um fator de percepção de normas sugeriu esse tema: Motivação como fator de efetivação na percepção e cumprimento das normas de conduta social. Assim foi feito um trabalho de campo sobre características pessoais em estudantes do 2º grau e sua percepção quanto as normas de ética pública. Variáveis de personalidade e atitude foram inseridas através de 4 escalas. Foi elaborado e testado um questionário de ética pública tendo sua fidedignidade comprovada. O tratamento estatístico das Escalas x Questionário foi feito através da Regressão Múltipla. Os resultados mostraram que 2 das variáveis medidas (personalidade e atitude) obtiveram correlação significativa em relação as normas de ética pública.

Fundamentos da psicologia social

O tema central deste estudo é o dos fundamentos da Psicologia Social. Neste sentido, foram examinados pressupostos ontológicos, epistemológicos, lógicos e axiológicos mas, também, as bases conceituais, teóricas e metodológicas deste setor da Psicologia contemporânea. A justificar este empreendimento, encontram-se duas suposições: a de que qualquer ciência é inexoravelmente construída sobre postulados metafísicos e lógicos, e a de que a falta de clareza em relação a estes impede a instalação de programas de pesquisa consequentes. Os objetivos colimados na consecução deste trabalho podem ficar assim discriminados: caracterização da Psicologia social; análise de suas bases filosóficas e lógicas; especificação da origem e classificação dos conceitos psicossociológicos; avaliação do estágio de teorização atingido na Psicologia Social; e discussão de aspectos epistemológicos da metodologia de pesquisa psicossociológica. Este texto pode ser classificado como filosófico. E pode sê-lo em virtude da natureza dos problemas submetidos à investigação e da metodologia empregada para este fim. São três as conclusões mais relevantes: em primeiro lugar, a de que em todas as ciências sociais e humanas, por subsistirem diversos pressupostos antropológicos ou imagens do Homem, cabe fomentar o pluralismo teórico; a de que nas disciplinas-psicológicas, a orientação nomotética - uma dentre várias alternativas doutrinárias existentes - deve continuar a ser desenvolvida; e, finalmente, a de que a Psicologia Social insere-se como elemento importante no processo de autoconsciência do Homem.

The life-cycle effects of social security in a model with housing and endogenous benefits

This article develops a life-cycle general equilibrium model with heterogeneous agents who make choices of nondurables consumption, investment in homeowned housing and labour supply. Agents retire from an specific age and receive Social Security benefits which are dependant on average past earnings. The model is calibrated, numerically solved and is able to match stylized U.S. aggregate statistics and to generate average life-cycle profiles of its decision variables consistent with data and literature. We also conduct an exercise of complete elimination of the Social Security system and compare its results with the benchmark economy. The results enable us to emphasize the importance of endogenous labour supply and benefits for agents' consumption-smoothing behaviour.

Os efeitos macroeconômicos das transferências sociais: uma abordagem de matriz de contabilidade social

Government transfers to individuals and families play a central role in the Brazilian social protection system, accounting for almost 14 per cent of GDP in 2009. While their fiscal and redistributive impacts have been widely studied, the macroeconomic effects of transfers are harder to ascertain. We constructed a Social Accounting Matrix (SAM) for 2009 and estimated short-term multipliers for seven different government monetary transfers . The SAM is a double-entry square matrix depicting all income flows in the economy. The data were compiled from the 2009 Brazilian National Accounts and the 2008/2009 POF, a household budget survey. Our SAM was disaggregated into 56 sectors, 110 commodities, 200 household groups and seven factors of production (capital plus six types of labor, according to schooling). Finally, we ran a set of regressions to separate household consumption into ‘autonomous’ (or ‘exogenous’) and ‘endogenous’ components. More specifically, we are interested in the effects of an exogenous injection into each of the seven government transfers outlined above. All the other accounts are thus endogenous. The so-called demand ‘leaks’ are income flows from the endogenous to exogenous accounts. Leaks—such as savings, taxes and imports—are crucial to determine the multiplier effect of an exogenous injection, as they allow the system to go back to equilibrium. The model assumes that supply is perfectly elastic to demand shocks. It assumes that the families’ propensity to save and consumption profile are fixed—that is, rising incomes do not provoke changes in behaviour. The multiplier effects of the on GDP corresponds to the growth in GDP resulting from each additional dollar injected into each transfer seven government transfers. If the government increased Bolsa Família expenditures by 1 per cent of GDP, overall economic activity would grow by 1.78 per cent, the highest effect. The Continuous Cash Benefit, comes second. Only three transfers— the private-sector and public servants’ pensions and FGTS withdrawals—had multipliers lower than unity. The multipliers for other relevant macroeconomic aggregates—household and total consumption, disposable income etc. —reveal a similar pattern. Thus, under the stringent assumptions of our model, we cannot reject the hypothesis that government transfers targeting poor households, such as the Bolsa Família, help foster economic expansion. Naturally, it should be stressed that the multipliers relate marginal injections into government transfers to short-term economic performance either real growth, or inflation if there is no idle capacity which is also useful to analyze. In the long term, there is no doubt that what truly matters is the growth of the country’s productive capacity.

As distintas percepções sobre o empreendedorismo social

This dissertation is a literature review with exploratory and descriptive purposes, which aims to compile the different perceptions of the term Social Entrepreneurship, but not propon-being of an epistemological analysis on the topic. The main objectives of this research were: 1) to identify the convergences and divergences in the various perceptions of the Social Entrepre-neurship, from the perspectives: American, European and Brazilian; 2) identify whether Social Entrepreneurship can be considered as a new theoretical trend, or can be understood as a sub-category of an existing theory; 3) identify whether Social Entrepreneurship can be considered as practice of Social Management; 4) identify whether the "Social Business", proposed by Yunus (2010), can be considered as a completely new type of organization, as the author says. For this research were studied literary works available in the physical environment and elec-tronic database. The main concepts studied in this research were: Entrepreneurship; Social Management; Third Sector; Business Management and Social Entrepreneurship. The conclu-sions reached by this study were: 1-a) the main theoretical convergence is the Social Entrepre-neur ability to apply methods and process typically used in for-profit companies, in business that aimed social value creation; 1-b) the main difference is the different perceptions that the United States, Europe and Brazil have about what is Social Entrepreneurship. In the American perspective, these are private sector organizations operating according to market logic and that somehow generates social value. In the European perspective, closer to the social economy, emphasizes the activities of civil society organizations with public functions. In Brazil empha-sizes market initiatives aimed at reducing poverty and transform the social conditions of mar-ginalized or excluded individuals; 2) Social Entrepreneurship is an activity that incorporates much all the practices, methods and processes of commercial entrepreneurship and, as such, should not be considered as a new theoretical trend, but a subcategory of Entrepreneurship theory. 3) Social Entrepreneurship cannot be considered as a practice of Social Management, being much closer to the commercial entrepreneurship practices; 4) the "Social Business" pro-posed by Yunus (2010), closely resembled in its modus operandi with the Social Enterprises in Western Europe, thus, not supporting the author's claim.

The impact of social security reform on occupational and retirement behavior : a quantitative assessment for Brazil

Population ageing is a problem that countries will have to cope with within a few years. How would changes in the social security system affect individual behaviour? We develop a multi-sectoral life-cycle model with both retirement and occupational choices to evaluate what are the macroeconomic impacts of social security reforms. We calibrate the model to match 2011 Brazilian economy and perform a counterfactual exercise of the long-run impacts of a recently adopted reform. In 2013, the Brazilian government approximated the two segregated social security schemes, imposing a ceiling on public pensions. In the benchmark equilibrium, our modelling economy is able to reproduce the early retirement claiming, the agents' stationary distribution among sectors, as well as the social security deficit and the public job application decision. In the counterfactual exercise, we find a significant reduction of 55\% in the social security deficit, an increase of 1.94\% in capital-to-output ratio, with both output and capital growing, a delay in retirement claims of public workers and a modification in the structure of agents applying to the public sector job.

Biology and behaviour of the neotropical ant-mimicking spider Aphantochilus rogersi (Araneae: Aphantochilidae): nesting, maternal care and ontogeny of ant-hunting techniques

Aphantochilus rogersi is an ant-mimicking spider that preys exclusively on cephalotine ants. The spiders oviposit in close proximity to nests of the model ant Zacryptocerus pusillus, and emergent spiderlings tend to remain in the vicinity of natal egg sacs. Females of A. rogersi actively defend their egg sacs against approaching workers of Z. pusillus, but the latter may sometimes destroy the eggs. Feeding specialization on these ants is confirmed by more than 300 observations of young and adult A. rogersi carrying ant corpses in the held. Although A. rogersi possesses several behavioural traits which may reduce the risk of being injured by ants during subjugation, field and laboratory observations showed that social defence by Z. pusillus may cause mutilation to the spiders. Tests in captivity revealed an ontogenetic change in the prey-capture techniques employed by A. rogersi. Early-instar spiderlings can apparently only seize the ant's petiole tightly if they are able to approach the ant from the front. As the ant is paralysed, the spiderling positions itself vertically in relation to the substratum. Larger spiders, on the other hand, attack ants most frequently from behind, and seem better equipped to seize the ant's petiole firmly with their larger chelicerae. Owing to their greater strength, late-instar spiders are able to Lift the struggling ant aloft. The selection of a suitable oviposition site, the mother's ability to defend herself and the eggs from nearby ants, and the capacity to capture and subdue ants safely from emergence to maturity, are regarded as crucial traits inherent in the mimetic and feeding specialization by A. rogersi.
