Desenvolvimento e valida??o de escalas brasileiras de percep??o e internaliza??o de normas corporais
Hirata, Elizabeth;Pérez-Nebra, Amalia Raquel;Pilati, Ronaldo;
Psicologia: Reflex?o e Crítica , 2012, DOI: 10.1590/S0102-79722012000100007
Abstract: the current research aimed at adapting, developing and validating brazilian scales related to body image norms for both genders. in study 1, sataq revealed a problematic two-factor structure. study 2 focused on the development of male and female body image scales. both scales revealed a two-factor structure, comprising the factors "general internalization" (factor loadings ranging from .85 to .37) and "behavioral intention" (factor loadings ranging from .73 to .38). in study 3, combined scales from study 1 and 2 were validated. besides that, correlational analyses with demographic data were performed. the analyses indicated a relation between reading, commenting and buying beauty products with body image norms. the final scale grouped sataq's and male and female body image scales' items, keeping the same factors of the two-factor structure.

Abstract: objectives: to investigate the usefulness of measuring upper airway collapsibility with a negative expiratory pressure application as a screening test for severe obstructive sleep apnea (osa). introduction: osa is a risk factor for cardiovascular disease, and it may have serious consequences. its recognition may have important implications during the perioperative period. increased upper airway collapsibility is one of the main determinants of osa, and its evaluation could be useful for identifying this condition. methods: severe osa and normal subjects (24 in each group) were matched by body mass index and referred to our sleep laboratory. the subjects were enrolled in an overnight sleep study, and a diurnal negative expiratory pressure test was performed. flow drop (dv) and expiratory volume were measured in the first 0.2 s (v02) of the negative expiratory pressure test. results: dv (%) and v02 (%) values were statistically different between normal and osa subjects. osa patients showed a greater decrease in flow than normal subjects. in addition, severely osa patients exhaled during the first 0.2 s of the negative expiratory pressure application was an average of only 11.2% of the inspired volume compared to 34.2% for the normal subjects. analysis of the receiver operating characteristics showed that v02 (%) and dv (%) could accurately identify severe osa in subjects with sensitivities of 95.8% and 91.7%, respectively, and specificities of 95.8% and 91.7%, respectively. conclusions: v02 (%) and dv (%) are highly accurate parameters for detecting severe osa. the pharyngeal collapsibility measurement, which uses negative expiratory pressure during wakefulness, is predictive of collapsibility during sleep.
Globaliza??o e divis?o sexual do trabalho
Hirata, Helena;
Cadernos Pagu , 2002, DOI: 10.1590/S0104-83332002000100006
Abstract: the discussion about the caracteristics and the limits of the notion of "globalization" will conduct us to the analysis of the deep transformations of the world(s) of work during the nineties. three issues interest us: first, the effects of globalization on the sexual division of labour; second, the new trends of female employment in the crisis; third, the french debate about the institutional and juridical alternatives related to the previous discussion about the "end of work" or the "centrality of work"; in conclusion, we will refer to the alternatives coming from the social mouvements against the employment crisis and the development of precariousness.
Tendências recentes da precariza??o social e do trabalho: Brasil, Fran?a, Jap?o
Hirata, Helena;
Caderno CRH , 2011, DOI: 10.1590/S0103-49792011000400002
Abstract: this paper aims to aprehend the new features of labor and social precarization, analyzed from the reality of the nineties by castel, showing how new trends are outlined in the process of globalization and current economic crisis, both in terms of settings sexual division of precarious labor as in terms of unprecedented modalities of repercussion on physical and mental health. the intensification of work in both the secondary and tertiary sectors and the expansion of outsourcing are phenomena in force in the three countries studied. from the analysis of recent processes of segmentation of employment in the labor market, this paper also seeks to address critically the concept of "precariousness", developed in opposition to society's "wageness", showing how the dynamics and the relationship between stable and precarious sectors are fundamental to the continuing process of capitalist development worldwide.
A precariza??o e a divis?o internacional e sexual do trabalho
Hirata, Helena;
Sociologias , 2009, DOI: 10.1590/S1517-45222009000100003
Abstract: the article examines the french researches on the precariousness of women's work, proposes some indicators of precarious employment, analyzes the most affected social groups, and demonstrates the relationship between the increasing vulnerability of women's employment and the process of globalization. some current social and scientific issues, such as the bipolarization of female employment and the increase in international migration of women are examined in the paper, as well as the current characteristics of work, wherein precariousness is concomitant with intensification of work and flexibilization. to conclude, the author considers the views that lead to the social and scientific legitimacy of this process of precarious employment, and the alternatives to this process, provided both by jurists and social movements.
Sistema em Leibniz e Descartes
Hirata, Celi;
Trans/Form/A??o , 2012, DOI: 10.1590/S0101-31732012000100003
Abstract: descartes thinks that the true scientific order is that of reasons, in which one starts from the easiest and most evident truths and moves towards those that are more difficult and complex. thus a unique, progressive, and irreversible order is established, where each member of the chain depends on those that precede it, and each thesis has a non-interchangeable place inside the doctrine. leibniz, on the contrary, defends the idea that "une même vérité peut avoir beaucoup des places selon les differents rapports qu'elle peut avoir" (nouveaux essais, iv, xxi, § 4 ; gp v, p. 506). in order to avoid repetition, assembling the greatest quantity of truths in a minimum of volumes, leibniz argues that the best scientific order is a systematic disposition in which each place refers to all the others, so that the connections among knowledge becomes clear. in opposition to the cartesian model of system, in the leibnizian model theses are based upon one another, and the order of truths is reversible. it is due to these differences concerning the conception of system that leibniz, unlike descartes, can pretend to take the best of each philosophical system in order to constitute his own, given that for him there is a certain malleability in the construction of a philosophical system.
Apercep o versus percep o: os espíritos na cosmologia leibniziana
Celi Hirata
Princípios : Revista de Filosofia , 2008,
Abstract: Leibniz states that every monad expresses the hole universe from a determined perspective. Therefore, all created beeings harmonize with each other, once that all of them represent the same world, as well each one individuates itself by means of its own point of view, which is determined by the place that its correspondent body occupies. However, if the capacity of representation is merely limited by space and time, how could one explain the capacity of spirits to grasp necessary and eternal truths and to establish science? In order to make this point clear I will introduce the aperception activity and distinguish it from the perception, that is common to all monads.
Putting Gross National Happiness in the Service of Good Development

Journal of Bhutan Studies , 2003,
Abstract: Gross National Happiness (GNH) has only recently appearedon the international stage,2 yet it was immediately met withsympathy by scholars, political activists, and politiciansaround the world. What is the reason for this strong appeal ofthis concept?In a historical perspective, the reason is probably adisillusionment with the broken promise of economic growthto truly improve people’s lives and bring about a moreequitable society. After a multifold increase of Gross NationalProduct in many societies thanks to almost continuouseconomic growth over more than a century, even thewealthiest societies are still plagued by grave social problemslike unemployment, child poverty, stress etc., and they aredisappointed that the hoped-for benefits of economic growthlargely failed to materialize.In a philosophical perspective, however, the reason for thesympathy extended to GNH seems to be based on an -intuitive or conscious - ethical endorsement of GNH as being1 I am grateful for valuable comments by the members of the“Berliner Forum” on a first conceptual draft of this paper and forsuggestions by Peter Ulrich on section six. All remaining errors aremy own.The question that arises then is if GNH is, or can beconceptualized as, an exhaustive concept of gooddevelopment that entirely fills in the ideal notion of gooddevelopment, or whether GNH is just one aspect of gooddevelopment that has to be complemented by additionalnormative concepts in order to appropriately substantiate theidea of good development.Whatever the answer to this question, the merit and thepotential of GNH to serve as a development concept is worthbeing investigated. To do so, the meaning of GNH has to bespecified since no generally accepted interpretation seems toexist. This is not only a disadvantage of course as thisconceptual openness invites a constructive debate on whatGNH should stand for and how it should be operationalized.These two - essentially ethical - questions will be at the centerof discussion in this paper.The paper is structured as follows: the next section willdiscuss the nature of happiness and its relation to humanbehavior and decision making in order to shed light on therelationship between happiness and ethics. I will then brieflypresent my understanding of (deontological) ethics, beforeexamining the relationship between happiness and economicgrowth on the basis of empirical evidence. I will then proposea particular interpretation of GNH and relate it to the conceptof good development. Towards the end, I will point out someimplications of my interpretation of GNH for itsoperati
