Um dos papéis da contabilidade é prover informações sobre o desempenho empresarial, quer seja por indicadores contábil-financeiros ou não. Dentro deste escopo do interesse da contabilidade, observa-se que a publicação de estudos teórico-empíricos sobre as relações entre Performance Corporativa Financeira (CFP) e a Performance Social Corporativa (CSP) vem crescendo nos últimos anos, sintoma do desenvolvimento deste campo de pesquisa. Entretanto, a contribuição à teoria pelos trabalhos empíricos se faz de forma pontual, uma vez que normalmente cada estudo foca um aspecto particular da teoria. Periodicamente, portanto, é necessária uma análise que avalie como, de forma agregada, os estudos empíricos contribuíram para a evolução da teoria, e elaborar essa análise constituiu o objetivo do presente estudo. O referencial teórico abrangeu: teoria dos stakeholders, relação entre CSP e CFP, good management theory e slack resource theory. Esta pesquisa abrangeu um período de 15 anos (1996 a 2010) e a coleta de dados empregou a ferramenta de busca das bases de dados: Ebsco, Proquest e ISI. O processo de amostragem obteve um conjunto de 58 artigos exclusivamente teórico-empíricos quantitativos que testam a relação CSP-CFP. Os principais resultados no campo teórico demonstram um reforço da proposição de relação positiva entre CSP e CFP e da good management theory, uma deficiência na explicação na defasagem de tempo (lag) na relação de causalidade entre CSP e CFP, e deficiências na descrição do constructo de CSP. Isto sugere estudos futuros para investigar a defasagem de tempo na relação de causalidade entre CSP e CFP e as possíveis razões que levaram diversos estudos empíricos a não atestarem uma associação positiva entre CSP e CFP.

The group presents an analysis of the development of the Czech society and economy during the 1990s. They believe that the Czech neo-liberal strategy of transformation led to a partial and uneven modernisation and that this strategy is unable to provide a firm basis for a complex process of modernisation. The increasing developmental problems encountered during 1996-1999 can be seen as empirical evidence of the inadequacy of the neo-liberal transformation strategy. These problems are connected to institutional shortcomings due to the excessive speed of privatisation, its form with certain important Czech innovations (particularly the voucher method and an attempt to resuscitate the Czech national capital) and with the overlooking of the importance of the legal framework and its enforcement. The overly hasty privatisation has created a type of 'recombinant property' which lacks the economic order necessary to stimulate efficiency in an atmosphere of prevailing social justice. A second reason for the present difficulties is the long-term lag behind the civilisation and cultural standards typical of the advanced European countries. The first steps of the Czech transformation concentrated mainly on changes in the institutions important for the distribution of power and wealth and largely neglected the necessity of deep-reaching modernisation of Czech society and the economy. The neo-liberal strategy created conditions conducive to predatory and speculative behaviour at the expense of creative behaviour. Inherited principles of egalitarianism combined with undeserved economic privileges survived and were reinforced by important new developments in the same direction. This situation hinders the assertion of meritocratic motivations. The group advocates the development and implementation of a complex strategy of modernisation based on deliberate reforms, institutional changes and restructuring on the basis of strategic planning, and structural and regional policies which stress the role of cultivation of the institutional order and of the most important factors of economic growth and development.

The research focused on children's behaviour in playing with objects both independently and in interaction with adults. It was based on studies of 40 Slovene children in 4 age groups (6,12,18 and 24 months) and of 23 Croatian children in 2 age groups (18 and 24 months). All the children were sampled proportionally by their gender and the educational level of their parents (middle and higher). Several coding check lists with satisfactory internal consistency were constructed during the study and used to analyse the video-recorded playing sessions with each child. The basic conclusion reached was that even in early childhood playing behaviour differs significantly between the infants from the two Central European countries. The difference lies not so much in the structure or the content of the playing actions, but in the way in which the infants deal playfully with the objects. This difference appears regardless of the type of object the infants are playing with and even regardless of the playing condition. It can best be described as the difference between the first significant discriminant function activity versus passivity. The Slovene infants were found to be on the active pole and the Croatians on the passive one. Social and gender differences were much less significant than cultural ones in determining the structure, the content and the way of playing. Significant age differences appeared in all three aspects, which was consistent with general trends in infants' psychological development. The group define the Slovene interactive playing style as object oriented, while the Croatian one was largely communicated oriented. Within the experimenter-infant dyads, children of both cultures played at a developmentally more advanced level than they did with their mothers, showing that the mothers were not as successful at reaching the ZPD as were the trained experimenters. In addition, the children of mothers who attributed more cognitive benefit to play played on a more advanced level than those whose mothers attributed more emotional benefit to play. The quality of the object the children were playing with was also significantly related to the structure, content and partly the way of dealing with the objects. Highly-structured objects stimulated complex play and low-structured ones stimulated simple play, regardless of playing conditions. The group concluded that both culture and the quality of the available object have an important impact on young children's play. Through the playing interaction, the infants internalise culturally specific patterns of behaviour and culturally specific meanings. These internalisations become apparent very early in their lives, even in non-social situations. On the other hand, the objects themselves have an impact on the level of infants' play. When they do not provide sufficient perceptive and functional support for a representational action, the infants' play will lag behind their actual developmental capacities.

The models of teaching social sciences and clinical practice are insufficient for the needs of practical-reflective teaching of social sciences applied to health. The scope of this article is to reflect on the challenges and perspectives of social science education for health professionals. In the 1950s the important movement bringing together social sciences and the field of health began, however weak credentials still prevail. This is due to the low professional status of social scientists in health and the ill-defined position of the social sciences professionals in the health field. It is also due to the scant importance attributed by students to the social sciences, the small number of professionals and the colonization of the social sciences by the biomedical culture in the health field. Thus, the professionals of social sciences applied to health are also faced with the need to build an identity, even after six decades of their presence in the field of health. This is because their ambivalent status has established them as a partial, incomplete and virtual presence, requiring a complex survival strategy in the nebulous area between social sciences and health.

Among the various ways of adopting the biographical approach, we used the curriculum vitaes (CVs) of Brazilian researchers who work as social scientists in health as our research material. These CVs are part of the Lattes Platform of CNPq - the National Council for Scientific and Technological Development, which includes Research and Institutional Directories. We analyzed 238 CVs for this study. The CVs contain, among other things, the following information: professional qualifications, activities and projects, academic production, participation in panels for the evaluation of theses and dissertations, research centers and laboratories and a summarized autobiography. In this work there is a brief review of the importance of autobiography for the social sciences, emphasizing the CV as a form of autobiographical practice. We highlight some results, such as it being a group consisting predominantly of women, graduates in social sciences, anthropology, sociology or political science, with postgraduate degrees. The highest concentration of social scientists is located in Brazil's southern and southeastern regions. In some institutions the main activities of social scientists are as teachers and researchers with great thematic diversity in research.

Mental health problems are common in primary health care, particularly anxiety and depression. This study aims to estimate the prevalence of common mental disorders and their associations with socio-demographic characteristics in primary care in Brazil (Family Health Strategy). It involved a multicenter cross-sectional study with patients from Rio de Janeiro, São Paulo, Fortaleza (Ceará State) and Porto Alegre (Rio Grande do Sul State), assessed using the General Health Questionnaire (GHQ-12) and the Hospital Anxiety and Depression Scale (HAD). The rate of mental disorders in patients from Rio de Janeiro, São Paulo, Fortaleza and Porto Alegre were found to be, respectively, 51.9%, 53.3%, 64.3% and 57.7% with significant differences between Porto Alegre and Fortaleza compared to Rio de Janeiro after adjusting for confounders. Prevalence proportions of mental problems were especially common for females, the unemployed, those with less education and those with lower incomes. In the context of the Brazilian government's moves towards developing primary health care and reorganizing mental health policies it is relevant to consider common mental disorders as a priority alongside other chronic health conditions.

OBJETIVOS: o objetivo deste trabalho foi verificar a incidência de cárie dentária em um programa de prevenção aplicado durante 25 anos em clínica particular. METODOLOGIA: participaram desse programa 640 crianças de ambos os gêneros, na faixa etária de 3 a 15 anos de idade. O programa foi baseado no controle mecânico da placa bacteriana dentária por meio da profilaxia profissional com jato de bicarbonato de sódio com uma periodicidade mensal. A incidência de cárie foi verificada por meio de exames clínicos durante as sessões de atendimento e radiográficos anualmente. A média de idade das crianças ao ingressarem no programa foi de 7,8 anos. RESULTADOS: antes de ingressar no programa, as crianças apresentaram, em média, 5,3 faces cariadas, enquanto após o programa a média foi de 0,18. A incidência de cáries por ano antes do programa foi de 0,9 faces cariadas e durante o programa de 0,03. O tempo de permanência das crianças no programa foi, em média, de 52,6 meses, e a média de faltas foi de 0,5 falta por ano. Esses resultados demonstram o sucesso do programa, principalmente por ter uma filosofia que procura o equilíbrio da biodiversidade da cavidade bucal, sem o risco de produzir efeitos colaterais indesejáveis. CONCLUSÕES: conclui-se, assim, que esse parece ser o caminho mais curto para resolver o problema da cárie dentária, ou seja, o controle mecânico da placa bacteriana dentária através da profilaxia profissional mensal, pois é um método de prevenção possível de ser aplicado em qualquer criança, independentemente de suas condições psicomotoras e sociais, e que proporciona a melhor relação custo-benefício, além de estar de acordo com os conceitos mais atuais de cárie e de seus fatores etiológicos. Em função da faixa etária das crianças, o programa é de suma importância para clínicas de Odontopediatria e Ortodontia.

A modified version of the intruder-resident paradigm was used to investigate if social recognition memory lasts at least 24 h. One hundred and forty-six adult male Wistar rats were used. Independent groups of rats were exposed to an intruder for 0.083, 0.5, 2, 24, or 168 h and tested 24 h after the first encounter with the familiar or a different conspecific. Factor analysis was employed to identify associations between behaviors and treatments. Resident rats exhibited a 24-h social recognition memory, as indicated by a 3- to 5-fold decrease in social behaviors in the second encounter with the same conspecific compared to those observed for a different conspecific, when the duration of the first encounter was 2 h or longer. It was possible to distinguish between two different categories of social behaviors and their expression depended on the duration of the first encounter. Sniffing the anogenital area (49.9% of the social behaviors), sniffing the body (17.9%), sniffing the head (3%), and following the conspecific (3.1%), exhibited mostly by resident rats, characterized social investigation and revealed long-term social recognition memory. However, dominance (23.8%) and mild aggression (2.3%), exhibited by both resident and intruders, characterized social agonistic behaviors and were not affected by memory. Differently, sniffing the environment (76.8% of the non-social behaviors) and rearing (14.3%), both exhibited mostly by adult intruder rats, characterized non-social behaviors. Together, these results show that social recognition memory in rats may last at least 24 h after a 2-h or longer exposure to the conspecific.
