Conceptual Rapprochement and the Analysis of the Historical, Normative and Jurisprudential Treatment of the Rural Workers, as Regards the Need for Special Protection

This article aims to present an approach to the issue of farm or rural zone workers, including a labour law study of agrarian legal decisions, so as to demonstrate their importance in respect to social, economic and cultural rights in Colombia. The study will serve to illustrate through the history, the applicable law and the jurisprudence, the different ways in which farmers have been treated from the time of the origin until the arrival of modern systems of industrialization. It calls into question the effectiveness of existing laws and the role of the courts, in spite of globalization, to maintain the minimum rights and guarantees of farm workers who are considered to be a vulnerable population. In conclusion, this study seeks to illustrate the current role of the Labor law and the National Health Service in the area of demonstrating of the existence or absence of mechanisms to protect workers in rural areas and the need to create some mechanisms that involve social justice given its prime importance in the Constitution of 1991.

An approximation to the informal-formal wage gap in Colombia 2008-2012

This document provides recent evidence about the persistency of wage gaps between formal and informal workers in Colombia by using a non-parametric method proposed by Ñopo (2008a). Over a rich dataset at a household level during 2008-2012, it is found that formal workers earn between 30 to 60 percent more, on average, than informal workers. Despite of the formality definition - structuralist or institucionalist- adopted, it is clear that formal workers have more economic advantages than informal ones, but after controlling by demographic and labor variables an important fraction of the gap still remains unexplained.

Perfil epidemiológico de la prevalencia de hipoacusia en un grupo de empleados que trabaja en el ambiente urbano, 2015

El propósito de este estudio es determinar la relación entre la exposición ocupacional y los niveles de audición en trabajadores urbanos en espacio abierto (aseo urbano en general). Se realizó un estudio de corte transversal con 491 personas que incluyen hombres y mujeres, cuyo ambiente laboral es el espacio abierto de la ciudad. Los datos se obtuvieron durante los exámenes médicos periódicos realizados en el año 2014 a los empleados de una empresa cuya actividad económica es el aseo urbano, que incluye recolección de basuras, cuidado forestal y de prados de uso común, y limpieza del borde de los andenes. Se realizó estadística descriptiva para las características demográficas y razón de disparidad u Odds Ratio (OR) para buscar la relación de antecedentes y hábitos personales con el riesgo de desarrollar pérdida auditiva. De las 491 personas expuestas a niveles altos de ruido ocupacional, 62% presentó pérdida auditiva, de los cuales la mayoría se desempeña como guadañadores y cortadores de césped, y son personas que llevan trabajando entre 1-5 años en la empresa. Se encontró un aumento estadísticamente significativo entre la baja escolaridad y el riesgo de sufrir hipoacusia (p=0.0001) y un efecto protector del uso de motocicleta y audífonos. La enfermedad vascular periférica, la práctica de tejo y la diabetes mostraron una fuerte tendencia a aumentar el riesgo. La pérdida auditiva encontrada en este grupo no se puede relacionar directamente con la exposición ocupacional a ruido, a pesar de ser trabajos que se llevan a cabo en el espacio urbano. Sin embargo, la baja escolaridad favorece la lesión auditiva y puede verse acelerada por enfermedades de alta prevalencia como diabetes y practicas recreacionales locales.

Factors affecting foster care breakdown in Spain

La ruptura del acogimiento familiar se ha definido como aquella situación en la que alguna de las partes implicadas causa una terminación de la intervención antes de haber alcanzado los objetivos establecidos en el plan de caso. Este trabajo presenta un estudio llevado a cabo en una muestra española de 318 casos cerrados de niños que fueron acogidos en familia ajena y extensa. Los datos se obtuvieron a través de la revisión exhaustiva de los expedientes de protección y acogimiento, complementada con entrevistas a los técnicos encargados de cada caso. La tasa de ruptura del conjunto de la muestra fue de 26,1%, si bien fue significativamente diferente en familia extensa (19,7%) que en familia ajena (31,2%). Los resultados de este estudio indican que las variables relacionadas con la ruptura dependen de la modalidad del acogimiento, en familia ajena o extensa. En el primer caso destacamos las variables relacionadas con las características del niño, especialmente los problemas de conducta y escolares, con especial relevancia en el grupo de 9-12 años, y el haber estado en acogimiento residencial previamente. En cambio, en extensa resulta más importante la problemática en los padres (prisión, salud mental) y el tener una medida de tutela. También el hecho de que se realice el acogimiento tras pasar por hogares de acogida resulta trascendental. Finalmente, la disponibilidad de recursos económicos e incluso los estudios de los acogedores parecen ser variables relacionadas con la ruptura de la acogida

A new concept for museum training in Germany

To talk about a new concept for museum training seems perhaps, to be a little bit exaggerated. For long time you have all been talking about concepts and contents for museum training and as I figured out the debate on the topic in Germany is as old as the appearance of national museums in the 19th century. Men like Theodor Mommsen, Rudolph Virchow, Alfred Lichtwark, all well known historians and supporters of the museum idea, spoke and wrote not only about the importance of museums as cultural and educational institutions but also supported the idea of professionalisation of museums work. Some of the ideas of our ancestors are still part of an ongoing discussion. The topic of my talk today will be what king of personnel a museum of our time needs to cope with the growing demand for internal and external organization. I shall present to you a new training program for museum workers in Germany which aims not to produce a new group of researchers but to prepare students for the practical work in the museum field.

Occupational hearing conservation in a rural woodworking company

This paper discusses a study to evaluate noise exposure and hearing thresholds of workers in a small woodworking company in a rural area.

Trends and gaps in the academic literature on EU labour migration policies. CEPS Paper in Liberty and Security No. 50/December 2012

This paper provides an overview of the ‘state of the art’ in the academic literature on EU labour migration policies. It forms part of the research agenda of Work Package 18 of the NEUJOBS project, which aims at reviewing legislation and practices regarding the labour market inclusion and protection of rights of different categories of foreign workers in European labour markets. Accordingly, particular attention is paid to the works of scholars who evaluate the status of rights of third-country national workers in relation to labour market access, employment security, social integration, etc., in European legislation on labour immigration. More specifically, the review has selected those scholarly works that focus specifically on analysing the manner in which policy-makers have addressed the granting of rights to non-EU migrant workers, and the manner in which policy agendas – through the relevant political and institutional dynamics – have found their translation in the legislation adopted. This paper consists of two core parts. In the first section, it reviews the works of scholars who have touched on these research questions with respect to the internal dimensions of EU labour migration policies. The second section does the same for the external dimensions of these policies. Both sections start off by analysing the main trends in the literature that reviews these questions for the internal and external dimensions of European migration policies as a whole, and then move on to how these ‘trends’ can (or cannot) be found translated in scholarly writings on labour migration policies more specifically. In the final section, the paper concludes by summarising the main trends and gaps in the literature reviewed, and indicates avenues for further research.

Poverty, migration and sex work: youth transitions in Ethiopia

Despite an emerging body of work on youth transitions, research has yet to explore the often unconventional routes to adulthood for young people marginalised through poverty. By drawing on interviews with 60 young commercial sex workers in Ethiopia, this paper explores the connections between poverty, migration and sex work and demonstrates that sex work provides a risky alternative, but often successful, path to independence for some rural-urban migrants. The paper concludes by offering recommendations for policies that seek to support young sex workers by enabling them to maintain their independence while seeking different employment.

Pesticides and other micro-organic contaminants in freshwater sedimentary environments - a review

A wide range of issues relating to the presence and fate of pesticides and other micro-organic contaminants (MOCs) in surface freshwater sedimentary environments is reviewed. These issues include the sources, transport and occurrence of MOCs in freshwater environments; their ecological effects; their interaction with sedimentary material; and a range of processes related to their fate, including degradation, diffusion in bed sediments, bioturbation and slow contaminant release. An emphasis is placed on those processes-chemical, physical or biological-in which sediments play a role in determining the fate of micro-organics in freshwater environments. The issues of occurrence, source and transport, and the ecological effects of micro-organics are introduced more briefly, the focus where these aspects are concerned being largely on pesticides. In the concluding section, key points and issues relating to the study of micro-organics in freshwater environments are summarised and areas where initial or further research would be welcome are highlighted. It is hoped that this paper will both form a useful reference for workers in the field of micro-organic contaminants, and also stimulate new work in the freshwater environment and beyond.

AIDS, mobility and commercial sex in Ethiopia: Implications for policy

Since the emergence of the AIDS pandemic in sub-Saharan Africa, male mobility has been highlighted as one of the reasons for the spread of the disease with men employing the services of commercial sex workers while away from home. However, sex workers' mobility and the implications of this for their access to prevention services, has largely been ignored. This paper, based on multi-method qualitative research with 60 young sex workers in two Ethiopian towns, reveals that sex workers are highly mobile, moving in order to attract a wider or different client base, for adventure and to conceal illnesses which might be associated with AIDS. In addition, sex workers are affected by restrictions on their movements, with girls working in bars and red-light areas having little free time to access projects. This paper advocates that policy approaches need to take account of this mobility in three ways: first, by exploring ways for girls to access information and maintain contact with support structures while moving between places of work; second, by building the capacity of sex workers to take greater control over decision-making in their day-to-day lives and third, by developing outreach strategies for taking services into bars and red-light areas.

Cellulose microfibril angle in the cell wall of wood fibres

The term microfibril angle (MFA) in wood science refers to the angle between the direction of the helical windings of cellulose microfibrils in the secondary cell wall of fibres and tracheids and the long axis of cell. Technologically, it is usually applied to the orientation of cellulose microfibrils in the S2 layer that makes up the greatest proportion of the wall thickness, since it is this which most affects the physical properties of wood. This review describes the organisation of the cellulose component of the secondary wall of fibres and tracheids and the various methods that have been used for the measurement of MFA. It considers the variation of MFA within the tree and the biological reason for the large differences found between juvenile (or core) wood and mature (or outer) wood. The ability of the tree to vary MFA in response to environmental stress, particularly in reaction wood, is also described. Differences in MFA have a profound effect on the properties of wood, in particular its stiffness. The large MFA in juvenile wood confers low stiffness and gives the sapling the flexibility it needs to survive high winds without breaking. It also means, however, that timber containing a high proportion of juvenile wood is unsuitable for use as high-grade structural timber. This fact has taken on increasing importance in view of the trend in forestry towards short rotation cropping of fast grown species. These trees at harvest may contain 50% or more of timber with low stiffness and therefore, low economic value. Although they are presently grown mainly for pulp, pressure for increased timber production means that ways will be sought to improve the quality of their timber by reducing juvenile wood MFA. The mechanism by which the orientation of microfibril deposition is controlled is still a matter of debate. However, the application of molecular techniques is likely to enable modification of this process. The extent to which these techniques should be used to improve timber quality by reducing MFA in juvenile wood is, however, uncertain, since care must be taken to avoid compromising the safety of the tree.
