Manufacturing real wages in Mexico

In this paper we analyse the recent evolution and determinants of real wages in Mexico’s manufacturing sector, using theories based on the assumption of imperfect competition both in the product and in the labour markets, especially wage-bargain theory, insider-outsider and mark-up models. We show evidence that the Mexican labour market does not behave as a traditional competitive market. The proposed explanation for this fact is that some workers benefit from advantages when compared with others, so that they can get a greater share of the proceedings of the productive process. Also, we find that changes in the degree of competition in the market for output influence the behaviour of real wages.

Welfare State e emprego em saúde nos países avançados desde o Pós-Segunda Guerra Mundial

The article analyzes the economic importance of the health activities in the developed countries in the last decades of the twentieth century. It takes into consideration the evolution of the weight of the employment in the health activities in European countries' and also in the United States' labour markets, which will be compared in an historical perspective. The evolution and the weight of the public expenditure in the health activities will also be taken into account so as to analyze the economic importance of the sector in the last decades of twentieth century. The role played by the political, economic and social context of the Post-Second World War in the construction of the system of social protection (Welfare State) and its effects over the health activities will be also considered.

Importância e aproveitamento da organização informal

Ao lado da organização formal, reconhece-se hoje a existência de uma organização informal bastante influente nos destinos de qualquer instituição. Há uma série de semelhanças entre os dois tipos de instituição, merecendo destaque a estrutura de relacionamentos, os sistemas de contrôle e comunicação, a existência de pessoas com autoridade, a permanência relativa de seus membros e a possibilidade de representação gráfica. Como essa organização informal é indestrutível, recomenda-se seja ela utilizada pela formal, o que, além de viável, é altamente vantajoso para a instituição como um todo. São expostas algumas formas de estudo e utilização da organização informal.

Microscopic analysis of "prato", "mussarela" and "mineiro" cheese sold in street markets of the City of S. Paulo, Southeastern Brazil

INTRODUCTION: Cheese should be produced from ingredients of good quality and processed under hygienic conditions. Further, cheese should be transported, stored and sold in an appropriate manner in order to avoid, among other things, the incorporation of extraneous materials (filth) of biological origin or otherwise, in contravention of the relevant food legislation. The aim of the study was to evaluate the hygienic conditions of "prato", "mussarela", and "mineiro" cheeses sold at the street food markets in the city of S. Paulo, Brazil. MATERIALS AND METHOD: Forty-seven samples of each of the three types of cheese were collected during the period from March, 1993 to February, 1994. The Latin square was used as a statistical model for sampling and random selection of the street markets from which to collect the cheese samples. The samples were analysed for the presence of extraneous matters outside for which purpose the samples were washed and filtered and inside, for which the methodology of enzymathic digestion of the sample with pancreatine, followed by filtering,was used. RESULTS AND CONCLUSION: Of the 141 samples analysed, 75.9% exhibited at least one sort of extraneous matters. For the "prato" and "mussarela" cheeses, the high number of contaminated samples was due mainly to extraneous matters present inside the cheese, whereas in the "mineiro" cheese, besides the internal filth, 100% of the samples had external filth.

Condiciones de salud y de trabajo informal en recuperadores ambientales del área rural de Medellín, Colombia, 2008

OBJETIVO: Caracterizar las condiciones de trabajo, salud y riesgos ocupacionales de recuperadores ambientales del área rural de Medellín. MÉTODOS: Estudio transversal con cien recuperadores ambientales informales en cinco corregimientos de Medellín en 2008. La fuente de información fue primaria: una encuesta estructurada sobre condiciones de trabajo, salud, riesgos ocupacionales y morbilidad sentida, que permitió caracterizar los riesgos de la población mediante estadística descriptiva y un acercamiento a las relaciones y asociaciones de los riesgos con la morbilidad en la población. RESULTADOS: Ciento cuatro personas ejercían el reciclaje, y 100 de estos se incluyeron en el estudio: 34 personas agremiadas en organizaciones de base comunitaria y 66 personas que ejercían la labor independientemente. La afiliación a seguridad social, suplencia de necesidades básicas, satisfacción en la labor, recibir capacitaciones y suministro periódico de elementos para su trabajo presentaron diferencias según grupo (p < 0,05). Los riesgos biológicos, relacionados con postura corporal inadecuada, riesgos físicos y químicos, tuvieran frecuencia particular de exposición según grupo. El conocimiento y uso de las medidas de protección para los riesgos de la labor difirieron estadísticamente entre los grupos (p < 0,05). CONCLUSÕES: Los recuperadores son potencial apoyo para la gestión integral de residuos en áreas rurales de Medellín, aunque su carácter informal los expone a condiciones de trabajo que repercuten directamente en su salud y la de sus familias. El reconocimiento social del reciclaje va de la mano con la mejora de las condiciones laborales de las personas dedicadas a esta actividad. Los recuperadores ambientales, aun agremiados, tienen condiciones laborales y de salud precarias. La trasformación de estas condiciones debería ser una de las prioridades del Estado.

CALLIPHORIDAE (DIPTERA) IN MANAUS: IV. BACTERIA ISOLATED FROM BLOWFLIES COLLECTED IN STREET MARKETS

Staphylococcus aureus, Escherichia coli, Proteussp., Providenciasp., Citrobactersp. and Klebsiellasp. were isolated from calliphorid flies collected in eight street markets in the city of Manaus, Amazonas State, Brazil. The presence of £. coliin the samples suggests that faecal contamination is occurring and that these flies are potential vehicles of enteropathogenic bacteria to exposed foods.

U.S. subprime financial crisis contagion on BRIC and European Union stock markets

ABSTRACTThe Copula Theory was used to analyze contagion among the BRIC (Brazil, Russia, India and China) and European Union stock markets with the U.S. Equity Market. The market indexes used for the period between January 01, 2005 and February 27, 2010 are: MXBRIC (BRIC), MXEU (European Union) and MXUS (United States). This article evaluated the adequacy of the main copulas found in the financial literature using log-likelihood, Akaike information and Bayesian information criteria. This article provides a groundbreaking study in the area of contagion due to the use of conditional copulas, allowing to calculate the correlation increase between indexes with non-parametric approach. The conditional Symmetrized Joe-Clayton copula was the one that fitted better to the considered pairs of returns. Results indicate evidence of contagion effect in both markets, European Union and BRIC members, with a 5% significance level. Furthermore, there is also evidence that the contagion of U.S. financial crisis was more pronounced in the European Union than in the BRIC markets, with a 5% significance level. Therefore, stock portfolios formed by equities from the BRIC countries were able to offer greater protection during the subprime crisis. The results are aligned with recent papers that present an increase in correlation between stock markets, especially in bear markets.

A família na unidade de internação hospitalar: entre o informal e o instituído

Estudo de abordagem comparada que utilizou duas etnografias já concluídas com o objetivo de identificar como as famílias percebem suas inserções na unidade de internação e como são percebidas pela equipe de saúde, considerando-se as regras e as normas da cultura institucional. Os resultados obtidos revelam que tanto as equipes quanto as famílias se aproximam ou se distanciam em face da concordância ou não das regras vigentes na instituição. Embora as famílias, em muitas situações, submetam-se aos regulamentos impostos pelo hospital e pela equipe, também usam resistências individuais e coletivas para enfrentar os mecanismos reguladores. Os resultados contribuem para aumentar a compreensão sobre o tema, tanto para a equipe de saúde quanto para a prática de enfermagem com famílias, especialmente no sentido de reconhecer as famílias como unidades ativas, responsáveis e coparticipantes na atenção intra-hospitalar.

Modes of acquisition of health literacy skills in informal learning contexts

In this article we try to analyze the learning processes of health literacy skills in informal contexts. We intend to broaden the understanding of the learning process beyond the formal contexts, thus contributing to the elucidation of health professionals on how individuals acquire and manage their knowledge in health matters. Given our goal, we use an analytic corpus constituted by one hundred autobiographical narratives written between 2006 and 2011, in educational contexts but with recognized potential for use in different scientific fields, including health. The results reveal the existence of three different types of modes of learning health literacy skills in informal context: : i) learning that takes place in action, in achieving daily tasks; ii) learning processes that result from problem solving; iii) learning that occurs in an unplanned manner, resulting from accidental circumstances and, in some cases, devoid of intentionality.

Development of the short version of the informal caregiver burden assessment questionnaire

OBJETIVE to create a reduced version of the QASCI, which is structurally equivalent to the long one and meets the criteria of reliability and validity. METHOD Through secondary data from previous studies, the participants were divided into two samples, one for the development of reduced version and the second for study of the factorial validity. Participants responded to QASCI, the SF 36, the ADHS and demographic questions. RESULTS A reduced version of 14 items showed adequate psychometric properties of validity and internal consistency, adapted to a heptadimensional structure that assesses positive and negative aspects of care. CONCLUSION Confirmatory factor analysis revealed a good fit with the advocated theoretical model.

Cross-cultural adaptation of the Caregiver Reaction Assessment for use in Brazil with informal caregivers of the elderly

This study aimed to carry out the cross-cultural adaptation of the Caregiver Reaction Assessment CRA for use in Brazil with informal caregivers of dependent elderly METHOD A methodological study, of five steps: initial translation, synthesis of translations, retro-translation, evaluation by a judge committee and a pre-test, with 30 informal caregivers of older persons in Fortaleza, Brazil. Content validity was assessed by five experts in gerontology and geriatrics. The cross-cultural adaptation was rigorously conducted, allowing for inferring credibility. RESULTS The Brazilian version of the CRA had a simple and fast application (ten minutes), easily understood by the target audience. It is semantically, idiomatically, experimentally and conceptually equivalent to the original version, with valid content to assess the burden of informal caregivers for the elderly (Content Validity Index = 0.883). CONCLUSION It is necessary that other psychometric properties of validity and reliability are tested before using in care practice and research.

Trabalho informal, gênero e raça no Brasil do início do século XXI

O artigo analisa a evolução do trabalho informal no Brasil, de 2001 a 2009, com base nas Pesquisas Nacionais por Amostra de Domicílio. Questões como "onde estão" os informais, "quem são", "quanto ganham" orientaram o estudo, tendo, além da comparação entre setor formal e informal, o gênero como foco. A heterogeneidade, marca do setor informal, é visível nos diversos setores econômicos, nas diferentes posições na ocupação, nas desiguais oportunidades de mulheres e negros em relação a homens e brancos. Apesar de o trabalho informal ter diminuído no Brasil durante a década, o pequeno crescimento registrado deveu-se ao ingresso das mulheres e, particularmente, das negras.

HILBERT BETWEEN THE FORMAL AND THE INFORMAL SIDE OF MATHEMATICS

Abstract: In this article we analyze the key concept of Hilbert's axiomatic method, namely that of axiom. We will find two different concepts: the first one from the period of Hilbert's foundation of geometry and the second one at the time of the development of his proof theory. Both conceptions are linked to two different notions of intuition and show how Hilbert's ideas are far from a purely formalist conception of mathematics. The principal thesis of this article is that one of the main problems that Hilbert encountered in his foundational studies consisted in securing a link between formalization and intuition. We will also analyze a related problem, that we will call "Frege's Problem", form the time of the foundation of geometry and investigate the role of the Axiom of Completeness in its solution.
