Segurança alimentar nos refeitórios de uma universidade portuguesa : aplicação da teoria do comportamento planeado

A Organização Mundial de Saúde estima que nos países mais industrializados uma em cada três pessoas sofra, por ano, de uma doença de origem alimentar. De acordo com os dados da Agência Europeia para a Segurança Alimentar foram relatados pelos 27 Estados Membros da União Europeia, no ano 2012, um total de 5.363 surtos de origem alimentar, assistindo-se a uma prevalência do setor da restauração, como o local de maior ocorrência dos surtos de doenças de origem alimentar. Para o mesmo ano, Portugal reportou 7 surtos de origem alimentar, envolvendo 135 pessoas com 42 hospitalizações. Neste contexto, a aplicação de boas práticas de higiene, nomeadamente no setor da restauração, é essencial para proteger o consumidor das doenças de origem alimentar. Neste estudo, pretendeu-se identificar os constructos do modelo da Teoria do Comportamento Planeado (Theory of Planned Behaviour – TPB, segundo a terminologia anglo-saxónica), de Icek Ajzen, que melhor explicam a intenção dos operadores de alimentos em adotarem os comportamentos de higiene, a saber: i) utilização de luvas e touca de proteção de cabelos, e ii) remoção de adornos pessoais, durante a manipulação de alimentos. Para o efeito, foi aplicado um questionário tendo por base a Teoria do Comportamento Planeado, a uma amostra de cento e vinte e três operadores dos vários refeitórios de uma universidade portuguesa, na sua grande maioria do sexo feminino (91,1%) e que manipulam alimentos numa base diária, recorrendo-se primeiramente a uma fase preliminar de estudo qualitativo, ou pré-inquérito, para melhor selecionar os temas essenciais e as principais categorias a considerar na construção deste inquérito. Os inquéritos foram tratados estatisticamente recorrendo-se à estatística descritiva, à análise fatorial e avaliação da consistência interna dos fatores resultantes, seguido da aplicação de regressão linear e metodologia de análise de trajetórias (path modeling) com vista à validação do TPB. Os resultados obtidos apontam para o fato de a Atitude ser o melhor preditor da Intenção em adotar os comportamentos em estudo. Verificou-se também que a motivação de cumprir resulta da pressão exercida pelos superiores hierárquicos ou colegas, influenciando positivamente a intenção, na medida em que as crenças normativas assumiram-se como sendo o segundo preditor que melhor previu a intenção.

Um olhar interdisciplinar sobre os suplementos alimentares: reconfiguração dos papéis profissionais no contexto das novas tendências de consumo terapêutico

O actual protagonismo que os suplementos alimentares têm vindo a assumir no quadro de novas lógicas de oferta e de consumo de recursos terapêuticos, constitui um facto que é revelador da emergência de novos fenómenos que geram reconfigurações importantes ao nível da dimensão social de novas práticas em torno destes mesmos recursos, com implicações no papel dos profissionais de farmácia. Face a este novo quadro, em que novas realidades profissionais se desenham como resposta a estes fenómenos, o olhar interdisciplinar que aqui se desenvolve procura problematizar os novos papéis dos profissionais ao nível do aconselhamento e da educação para a saúde. Sustenta-se que esse objectivo dificilmente poderá ser mais do que um mero horizonte normativo, se não for capaz de integrar as abordagens de carácter sociológico sobre as importantes reconfigurações das dinâmicas de autonomia e reflexividade leiga que têm vindo a ocorrer em termos de gestão da saúde e de consumos terapêuticos. The current role that dietary supplements have been playing under new logic of supply and consumption of therapeutic resources, is a fact that reveals the emergence of new phenomena that generate major reconfigurations to the social dimension of new practices around these resources, with implications for the professional role of pharmacy practitioners. In this new framework, in which new realities are emerging as a professional response to these phenomena, the interdisciplinary outlook that we develop aims to raise some critical questions concerning the development of new roles in pharmacy practitioners in counseling and health education. We assert that this goal will scarcely be more than just a normative horizon, if unable to integrate the nature of sociological approaches on important reconfiguration of the dynamics of lay autonomy and reflexivity that have been occurring in terms of health management and therapeutic consumptions.

Return premiums of sustainable companies listed on the Spanish stock market

The purpose of this paper is to analyze whether companies with a greater commitment to corporate social responsibility (SRI companies) perform differently on the stock market compared to companies that disregard SRI. Over recent years, this relationship has been taken up at both a theoretical and practical level, and has led to extensive scientific research of an empirical nature involving the examination of the relationships existing between the financial and social, environmental and corporate governance performance of a company and the relationship between SRI and investment decisions in the financial market. More specifically, this work provides empirical evidence for the Spanish market as to whether or not belonging to a group of companies the market classes as sustainable results in return premiums that set them apart from companies classed as conventional, and finds no differences in the stock market performance of companies considered to be SRI or conventional.

Changes in the influence of board characterisitcs on corporate results due to the recent global financial crisis

The main purpose of this study is to analyse the changes caused by the global financial crisis on the influence of board characteristics on corporate results, in terms of corporate performance, corporate risk-taking, and earnings management. Sample comprises S&P 500 listed firms during 2002-2008. This study reveals that the environmental conditions call for different behaviour from directors to fulfil their responsibilities and suggests changes in normative and voluntary guidelines for improving good practices in the boardroom.

Impactos da acalmia de tráfego na sinistralidade rodoviária das travessias urbanas: casos de estudo - Lagoa e Albufeira

Em Portugal os acidentes com vítimas ocorridos no interior das localidades representaram 73% da totalidade dos acidentes com vítimas registados em 2010. Apesar de todo o esforço empregue nesse sentido, as particularidades das áreas urbanas e de todas as vivências que lhes estão associadas, exigem um maior empenho no sentido de prevenir e mitigar os riscos de acidentes presentes num ambiente urbano. A acalmia de tráfego surge como uma possível solução de prevenção de todos os tipos de conflitos originados pelas diferentes velocidades de circulação que caracterizam cada um dos modos de transporte presentes nos aglomerados urbanos. Felizmente, apesar de se tratar de uma fase ainda inicial, em Portugal já existem alguns casos de situações urbanas tratadas com recurso a técnicas de acalmia de tráfego. Este trabalho vai no sentido de avaliar, através de dados relativos à sinistralidade, qual o real impacto e dividendos deste tipo de solução na redução do número de acidentes ocorridos no interior das localidades, particularmente na ocorrência de atropelamentos, uma vez que acarreta custos sociais e económicos elevadíssimos. As zonas alvo deste estudo foram os Concelhos de Lagoa e Albufeira, que são atravessados pela Estrada Nacional 125, tornando-se um caso típico de atravessamento urbano onde as medidas de acalmia de tráfego implementadas demonstraram alguma eficácia no aumento da segurança rodoviária no interior das zonas estudadas.

Ensaios de carga em Portugal: viabilidade de normalização

Esta Dissertação de Mestrado subordina-se ao tema: “Normalização de Ensaios de Carga”, sendo esta uma temática pouco desenvolvida em Portugal e para a qual não existe qualquer legislação. Os ensaios de carga são realizados em Portugal sem que haja uma legislação que normalize a sua realização e por isso cada entidade segue a sua metodologia nomeadamente entidades como o Laboratório Nacional de Engenharia Civil (LNEC) ou a Faculdade de Engenharia da Universidade do Porto (FEUP). Os objectivos principais deste trabalho são o estudo da legislação estrangeira existente para ensaios de carga e o seu confronto com as metodologias seguidas em Portugal, com o intuito de identificar aspectos consensuais e controversos e definir questões que possam ser transpostas para um documento normativo português. Este trabalho inicia-se com uma pesquisa bibliográfica, através da qual vão ser abordados conceitos básicos sobre os ensaios de carga como os seus objectivos, os tipos de ensaios ou o modo de tratamento de resultados e será elaborada uma breve resenha histórica dos ensaios de carga. É estudada a legislação existente noutros países, seleccionando-se os aspectos mais relevantes. São também abordadas as metodologias adoptadas por diversas entidades em Portugal como o LNEC e a FEUP. Por último, numa vertente mais analítica serão seleccionados os aspectos mais relevantes da legislação internacional e será estabelecido o confronto com as metodologias seguidas em Portugal de maneira a identificar aspectos relevantes a constar num documento normativo a elaborar futuramente em Portugal.

O modelo das demonstrações financeiras de acordo com o SNC

Neste trabalho, discutimos e analisamos as Demonstrações Financeiras (DF) elaboradas de acordo com a proposta do Sistema de Normalização Contabilística (SNC), apresentada pela Comissão de Normalização Contabilística (CNC), comparativamente com as DF preparadas de acordo com o Plano Oficial de Contabilidade (POC), em vigor em Portugal por imposição do Decreto-Lei n.º 410/89, de 21 de Novembro. Assim, marcamos separadamente os aspectos normativos que norteiam a execução dessas DF com referências comparativas entre elas, não com intuito de subjugar umas em detrimento de outras, mas de mostrar as suas diferenças em relação à essência, forma e finalidade. In this work, we discuss and analyze the Financial Reports (FR) made in accordance with the essay of Sistema de Normalização Contabilística (SNC) and presented by Comissão de Normalização Contabilística (CNC). In addition, we made a comparison with the FR prepared following the Plano Oficial de Contabilidade (POC) that is in use in Portugal by legal origin (Decreto-Lei n.º 410/89, de 21 de Novembro). Therefore, we emphasize the normative issues that drive FR construction with systematic comparisons between both. We do not aim to determine which one is the best normative, but to examine their differences related with essence, methods and goals.

Eastwards / westwards: which direction for gender studies in the 21st century?

Eastwards / Westwards: Which Direction for Gender Studies in the XXIst Century? is a collection of essays which focus on themes and methods that characterize current research into gender in Asian countries in general. In this collection, ideas derived from Gender Studies elsewhere in the world have been subjected to scrutiny for their utility in helping to describe and understand regional phenomena. But the concepts of Local and Global – with their discoursive productions – have not functioned as a binary opposition: localism and globalism are mutually constitutive and researchers have interrogated those spaces of interaction between the ‘self’ and the ‘other’, bearing in mind their own embeddedness in social and cultural structures and their own historical memory. Contributors to this collection provided a critical transnational perspective on some of the complex effects of the dynamics of cultural globalization, by exploring the relation between gender and development, language, historiography, education and culture. We have also given attention to the ideological and rhetorical processes through which gender identity is constructed, by comparing textual grids and patterns of expectation. Likewise, we have discussed the role of ethnography, anthropology, historiography, sociology, fiction, popular culture and colonial and post-colonial sources in (re)inventing old/new male/female identities, their conversion into concepts and circulation through time and space. This multicultural and trans-disciplinary selection of essays is totally written in English, fully edited and revised, therefore, it has a good potential for an immediate international circulation. This project may trace new paths and issues for discussion on what concerns the life, practices and narratives by and about women in Asia, as well as elsewhere in the present day global experience. Academic readership: Researchers, scholars, educators, graduate and post-graduate students, doctoral students and general non-fiction readers, with a special interest in Gender Studies, Asia, Colonial and Post-Colonial Literature, Anthropology, Cultural Studies, History, Historiography, Politics, Race, Feminism, Language, Linguistics, Power, Political and Feminist Agendas, Popular Culture, Education, Women’s Writing, Religion, Multiculturalism, Globalisation, Migration. Chapter summary: 1. “Social Gender Stereotypes and their Implication in Hindi”, Anjali Pande, Jawaharlal Nehru University, New Delhi, India. This essay looks at the subtle ways in which gender identities are constructed and reinforced in India through social norms of language use. Language itself becomes a medium for perpetuating gender stereotypes, forcing its speakers to confirm to socially defined gender roles. Using examples from a classroom discussion about a film, this essay will highlight the underlying rigid male-female stereotypes in Indian society with their more obvious expressions in language. For the urban woman in India globalisation meant increased economic equality and exposure to changed lifestyles. On an individual level it also meant redefining gender relations and changing the hierarchy in man-­woman relationships. With the economic independence there is a heightened sense of liberation in all spheres of social life, a confidence to fuzz the rigid boundaries of gender roles. With the new films and media celebrating this liberated woman, who is ready to assert her sexual needs, who is ready to explode those long held notions of morality, one would expect that the changes are not just superficial. But as it soon became obvious in the course of a classroom discussion about relationships and stereotypes related to age, the surface changes can not become part of the common vocabulary, for the obvious reason that there is still a vast gap between the screen image of this new woman and the ground reality. Social considerations define the limits of this assertiveness of women, whereas men are happy to be liberal within the larger frame of social sanctions. The educated urban woman in India speaks in favour of change and the educated urban male supports her, but one just needs to scratch the surface to see the time tested formulae of gender roles firmly in place. The way the urban woman happily balances this emerging promise of independence with her gendered social identity, makes it necessary to rethink some aspects of looking at gender in a gradually changing, traditional society like India. 2. “The Linguistic Dimension of Gender Equality”, Alissa Tolstokorova, Kiev Centre for Gender Information and Education, Ukraine. The subject-matter of this essay is gender justice in language which, as I argue, may be achieved through the development of a gender-related approach to linguistic human rights. The last decades of the 20th century, globally marked by a “gender shift” in attitudes to language policy, gave impetus to the social movement for promoting linguistic gender equality. It was initiated in Western Europe and nowadays is moving eastwards, as ideas of gender democracy progress into developing countries. But, while in western societies gender discrimination through language, or linguistic sexism, was an issue of concern for over three decades, in developing countries efforts to promote gender justice in language are only in their infancy. My argument is that to promote gender justice in language internationally it is necessary to acknowledge the rights of women and men to equal representation of their gender in language and speech and, therefore, raise a question of linguistic rights of the sexes. My understanding is that the adoption of the Universal Declaration of Linguistic Rights in 1996 provided this opportunity to address the problem of gender justice in language as a human rights issue, specifically as a gender dimension of linguistic human rights. 3. “The Rebirth of an Old Language: Issues of Gender Equality in Kazakhstan”, Maria Helena Guimarães, Polytechnic Institute of Porto, Portugal. The existing language situation in Kazakhstan, while peaceful, is not without some tension. We propose to analyze here some questions we consider relevant in the frame of cultural globalization and gender equality, such as: free from Russian imperialism, could Kazakhstan become an easy prey of Turkey’s “imperialist dream”? Could these traditionally Muslim people be soon facing the end of religious tolerance and gender equality, becoming this new old language an easy instrument for the infiltration in the country of fundamentalism (it has already crossed the boarders of Uzbekistan), leading to a gradual deterioration of its rich multicultural relations? The present structure of the language is still very fragile: there are three main dialects and many academics defend the re-introduction of the Latin alphabet, thus enlarging the possibility of cultural “contamination” by making the transmission of fundamentalist ideas still easier through neighbour countries like Azerbaijan, Uzbekistan and Turkmenistan (their languages belong to the same sub-group of Common Turkic), where the Latin alphabet is already in use, and where the ground for such ideas shown itself very fruitful. 4. “Construction of Womanhood in the Bengali Language of Bangladesh”, Raasheed Mahmood; University of New South Wales, Sydney. The present essay attempts to explore the role of gender-based language differences and of certain markers that reveal the status accorded to women in Bangladesh. Discrimination against women, in its various forms, is endemic in communities and countries around the world, cutting across class, race, age, and religious and national boundaries. One cannot understand the problems of gender discrimination solely by referring to the relationship of power or authority between men and women. Rather one needs to consider the problem by relating it to the specific social formation in which the image of masculinity and femininity is constructed and reconstructed. Following such line of reasoning this essay will examine the nature of gender bias in the Bengali language of Bangladesh, holding the conviction that as a product of social reality language reflects the socio-cultural behaviour of the community who speaks it. This essay will also attempt to shed some light on the processes through which gender based language differences produce actual consequences for women, who become exposed to low self-esteem, depression and systematic exclusion from public discourse. 5. “Marriage in China as an expression of a changing society”, Elisabetta Rosado David, University of Porto, Portugal, and Università Ca’Foscari, Venezia, Italy. In 29 April 2001, the new Marriage Law was promulgated in China. The first law on marriage was proclaimed in 1950 with the objective of freeing women from the feudal matrimonial system. With the second law, in 1981, values and conditions that had been distorted by the Cultural Revolution were recovered. Twenty years later, a new reform was started, intending to update marriage in the view of the social and cultural changes that occurred with Deng Xiaoping’s “open policy”. But the legal reform is only the starting point for this case-study. The rituals that are followed in the wedding ceremony are often hard to understand and very difficult to standardize, especially because China is a vast country, densely populated and characterized by several ethnic minorities. Two key words emerge from this issue: syncretism and continuity. On this basis, we can understand tradition in a better way, and analyse whether or not marriage, as every social manifestation, has evolved in harmony with Chinese culture. 6. “The Other Woman in the Portuguese Colonial Empire: The Case of Portuguese India”, Maria de Deus Manso, University of Évora, Portugal. This essay researches the social, cultural and symbolic history of local women in the Portuguese Indian colonial enclaves. The normative Portuguese overseas history has not paid any attention to the “indigenous” female populations in colonial Portuguese territories, albeit the large social importance of these social segments largely used in matrimonial and even catholic missionary strategies. The first attempt to open fresh windows in the history of this new field was the publication of Charles Boxer’s referential study about Women in lberian Overseas Expansion, edited in Portugal only after the Revolution of 1975. After this research we can only quote some other fragmentary efforts. In fact, research about the social, cultural, religious, political and symbolic situation of women in the Portuguese colonial territories, from the XVI to the XX century, is still a minor historiographic field. In this essay we discuss this problem and we study colonial representations of women in the Portuguese Indian enclaves, mainly in the territory of Goa, using case studies methodologies. 7. “Heading East this Time: Critical Readings on Gender in Southeast Asia”, Clara Sarmento, Polytechnic Institute of Porto, Portugal. This essay intends to discuss some critical readings of fictional and theoretical texts on gender condition in Southeast Asian countries. Nowadays, many texts about women in Southeast Asia apply concepts of power in unusual areas. Traditional forms of gender hegemony have been replaced by other powerful, if somewhat more covert, forms. We will discuss some universal values concerning conventional female roles as well as the strategies used to recognize women in political fields traditionally characterized by male dominance. Female empowerment will mean different things at different times in history, as a result of culture, local geography and individual circumstances. Empowerment needs to be perceived as an individual attitude, but it also has to be facilitated at the macro­level by society and the State. Gender is very much at the heart of all these dynamics, strongly related to specificities of historical, cultural, ethnic and class situatedness, requiring an interdisciplinary transnational approach.

Supporting leadership development by exposure to role models: two case studies

The idiomatic expression “In Rome be a Roman” can be applied to leadership training and development as well. Leaders who can act as role models inspire other future leaders in their behaviour, attitudes and ways of thinking. Based on two examples of current leaders in the fields of Politics and Public Administration, I support the idea that exposure to role models during their training was decisive for their career paths and current activities as prominent characters in their profession. Issues such as how students should be prepared for community or national leadership as well as cross-cultural engagement are raised here. The hypothesis of transculturalism and cross-cultural commitment as a factor of leadership is presented. Based on current literature on Leadership as well as the presented case studies, I expect to raise a debate focusing on strategies for improving leaders’ training in their cross-cultural awareness.
