ABSTRACT

Samir Amin was one of the most creative Marxists, but also an orthodox, as his appeal for a new international proves, consistent with his defense of the socialist revolution against a decaying capitalist system, which threatens with the extinction of human civilization. However, in a contradictory way, if in the past the material conditions did not exist, they exist today, materializing in a distorted manner by capitalism, the organization of a revolutionary international leadership has never been so non-existent. This article begins by demonstrating the systemic conditions that require the proletariat to build a new International, the reasons for the current difficulty in achieving it; and, from the analysis of the most successful experience to date, the Third International, lessons are drawn for a future Fifth International.  相似文献

This paper discusses a research agenda that arises from unanswered questions and unresolved issues considered in the World Bank’s World Development Report 2006: Equity and Development. After formalizing the key concepts of equity; equality of opportunity; and efficiency, and proposing a definition for an equitable development policy, the paper discusses the concept of inequality traps, around which the research agenda is structured. Four broad groups of research questions are highlighted: those revolving around the measurement of inequality of opportunity and the diagnostics for the existence of an inequality trap; those dealing with the causes of inequality traps; the quantification of their efficiency costs; and those related to how institutions (including governments) evolve to overcome inequality traps. Bourguignon and Ferreira are in the Development Economics Vice-Presidency, The World Bank. Michael Walton is at the John F. Kennedy School of Government, Harvard University. Together, they led the team that produced the World Bank’s World Development Report 2006: Equity and Development.  相似文献

Introduction

The following quantitative observational study aimed to analyse the maternal and neonatal outcomes of 90 low-risk pregnant women who gave birth in water at São Bernardo Hospital.

Methods

A form containing information on the obstetric history of the parturient, the type of immersion, and the labour and birth follow-up was used by midwives to collect the data.

Background

The Apgar score (at 1 min after birth) used in this study, called Aqua Apgar, was adapted by Cornelia Enning.

Results

The mean water immersion time was 1 h and 46 min and had an influence on the duration of labour (mean 5 h and 37 min), with a statistically significant difference (P = 0.004). There was a decreased cervical dilatation time and a shorter duration of the expulsion phase. In the immersion scenario, 30% of the women did not undergo any examination to assess the length of the cervix, and 57.8% presented intact perennial areas or first-degree tears. As for neonatal outcomes, during maternal immersion, 97% maintained normal fetal heart rates (between 110 and 160 beats per minute) and Aqua Apgar was higher than 7, both in the first minute (mean of 9.4) and in the fifth minute of life (mean of 9.9).

Conclusion

These safety outcomes, based on sound scientific evidence, should increasingly support and inform clinical decisions and increase the number of waterbirths in health facilities. The results of this study align with growing evidence that suggests waterbirth is a safe delivery option and therefore should be offered to women.  相似文献

The absence of a translated and validated instrument for measuring marital satisfaction in Brazil, the largest country in South America and fifth most populous country in the world, is a significant barrier for research and mental health service delivery. The purpose of this study was to translate and validate a marital satisfaction scale into Portuguese that would have both empirical credibility and cultural relevance in Brazil. A six-step serial approach was used to simultaneously translate and culturally validate the Revised Dyadic Adjustment Scale (RDAS). The translated instrument (RDAS-P) demonstrated good psychometric properties during field testing.  相似文献

The aim of the present study is to contribute to the analysis of employment and work conditions of Portuguese trainers, as well as to identify conditions, resources, demands and constraints of their work activities. Despite the lack of scientific knowledge on professional training, the topic has been playing a central role in modern societies. Several data collection strategies were used, namely the application of INSAT to 72 trainers, exploratory interviews with 10 trainers and collective interviews with 6 trainers. The analysis of the data collected highlights the changes in the selection of human resources in the sector as well as the contractual terms of the trainers, mainly independent workers. The intra and inter individual variability of working hours and the diversity of activities performed by each trainer also stands out. Finally, it is important to refer the spontaneous organization of trainers' work activities according to their training modality.  相似文献

In the workplace there are risk factors that can overwhelm the health of the worker causing physical and psychological disorders. Among these disorders, is occupational stress. Thus, this research proposes to measure the mental workload of job stress from the identification of demand, control and social support. It is an observational cross-sectional epidemiological character, performed with the Rectory office workers at the State University of West Paraná (Unioeste). Data collection was due to the application of the "Job Stress Scale" (JSS) and in its reduced version adapted to Portuguese. The survey sample consisted of 44 individuals. Statistical analysis was correlated inversely with medium intensity (r = -0.404) between age and social support. For males was found between control and age (r = 0.603). According to the data obtained, we conclude that most workers are exposed to passive work, leading to loss of skills or disinterest in the job. This study highlights the importance of research in the area and the need for new actions that change the conditions of stress at work.  相似文献

Following the technological developments and presented to the multidisciplinary processes as automakers, Volkswagen Brazil, represented by its ergonomists, through this paper, shows the importance of ergonomic efficiency of management applied to various levels of life of a product, since its creation to its final implementation on production lines.The preventive work of ergonomists during the processes leading to production of a vehicle is accomplished through assessments on a simulated system called the Digital Factory. Since the initial stages to final product delivery there is a need for a multidisciplinary aligning the concepts of ergonomics, productivity and quality of product. Industrial Engineering, Process Engineering, ergonomists and workers are involved in the analysis made through the Workshop's showing the importance of discussion between the various users of the systems. The processes of series are also equipped with a set of certifications flow of job and planned audits on items that describe processes and applied ergonomics.  相似文献
