As diferenças de género na percepção do conflito trabalho-família

O crescente interesse na compreensão e na gestão da interface trabalho-família provém das já demonstradas consequências do conflito trabalho-família no bem estar profissional e pessoal e no desempenho dos papéis de trabalho e de família. A participação das mulheres na força de trabalho levou a que combinem as responsabilidades familiares e profissionais. A combinação do papel de trabalho e do papel de família poderá levar ao conflito trabalho-família. A investigação realizada centra-se na forma como os indivíduos manipulam as exigências do trabalho e da família na tentativa de criar modelos de relacionamento e de actividades que sejam gerí- veis. Actualmente, as preocupações dos investigadores vão mais longe e procuram, também, encontrar soluções no local de trabalho que facilitem a conciliação entre o trabalho e a família. O objectivo deste estudo é o de verificar a existência e as diferenças na percepção do conflito trabalho- família entre homens e mulheres. Os dados foram obtidos através de entrevistas a 33 trabalhadores de uma empresa de produtos lácteos.

To this effect, the production of the general conditions of infrastructure, equipment, services, and the production process of the production units (housing) conform the basic unit for the reproduction of the labour force and capital. The infrastructure, the equipment, the public spaces, the green areas, education services, health, and the socio cultural device, fulfil a fundamental function in the creation of the essential conditions for the reproduction of the labour force and the simple and extended accumulation of capital.From this perspective, this article will focus on the aspects relative to the construction of space and the production of housing, in a double dimension, the production of residential space and the production of housing.

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.

Making the Most of EU Labour Mobility. Report of a CEPS Task Force in Cooperation with the Bertelsmann Foundation. CEPS Task Force Report, 7 October 2014

This Task Force report combines the most recent data from Eurostat with national sources to highlight the most significant labour mobility trends within the EU. Overall, the recent recession has not induced previously immobile workers to become more mobile, at least not in the larger member states. Mobility flows have moved away from crisis countries in response to the economic downturn but the desired increase in south-north mobility has not been observed so far. This leads the authors to conclude that successfully fostering mobility within EU15 countries requires tremendous effort. It is important that workers who are willing and able to move are not discouraged from doing so by unnecessary barriers to mobility. Improving the workings of the EURES system and its online job-matching platform; better cooperation of national employment agencies; streamlining the recognition of qualifications; and supporting language training within the EU are important contributions to labour mobility. The authors conclude that the EU is right to defend the free movement of workers. National governments should keep in mind that their ability to tap into an attractive foreign labour supply also hinges upon the perception of how mobile workers are treated in destination countries. If the political imperative requires regulations to be changed, such as the one guiding the coordination of social security, it is essential that no new mobility barriers are put in place.

Which firms want PhDs? The effect of the university-industry relationship on the PhD labour market

PhD graduates hold the highest education degree, are trained to conduct research and can be considered a key element in the creation, commercialization and diffusion of innovations. The impact of PhDs on innovation and economic development takes place through several channels such as the accumulation of scientific capital stock, the enhancement of technology transfers and the promotion of cooperation relationships in innovation processes. Although the placement of PhDs in industry provides a very important mechanism for transmitting knowledge from universities to firms, information about the characteristics of the firms that employ PhDs is very scarce. The goal of this paper is to improve understanding of the determinants of the demand for PhDs in the private sector. Three main potential determinants of the demand for PhDs are considered: cooperation between firms and universities, R&D activities of firms and several characteristics of firms, size, sector, productivity and age. The results from the econometric analysis show that cooperation between firms and universities encourages firms to recruit PhDs and point to the existence of accumulative effects in the hiring of PhD graduates.

The Wage-Productivity gap revisited: is the labour share neutral to employment?

This paper challenges the prevailing view of the neutrality of the labour income share to labour demand, and investigates its impact on the evolution of employment. Whilst maintaining the assumption of a unitary long-run elasticity of wages with respect to productivity, we demonstrate that productivity growth affects the labour share in the long run due to frictional growth (that is, the interplay of wage dynamics and productivity growth). In the light of this result, we consider a stylised labour demand equation and show that the labour share is a driving force of employment. We substantiate our analytical exposition by providing empirical models of wage setting and employment equations for France, Germany, Italy, Japan, Spain, the UK, and the US over the 1960-2008 period. Our findings show that the timevarying labour share of these countries has significantly influenced their employment trajectories across decades. This indicates that the evolution of the labour income share (or, equivalently, the wage-productivity gap) deserves the attention of policy makers.

SwissParam: a fast force field generation tool for small organic molecules.

The drug discovery process has been deeply transformed recently by the use of computational ligand-based or structure-based methods, helping the lead compounds identification and optimization, and finally the delivery of new drug candidates more quickly and at lower cost. Structure-based computational methods for drug discovery mainly involve ligand-protein docking and rapid binding free energy estimation, both of which require force field parameterization for many drug candidates. Here, we present a fast force field generation tool, called SwissParam, able to generate, for arbitrary small organic molecule, topologies, and parameters based on the Merck molecular force field, but in a functional form that is compatible with the CHARMM force field. Output files can be used with CHARMM or GROMACS. The topologies and parameters generated by SwissParam are used by the docking software EADock2 and EADock DSS to describe the small molecules to be docked, whereas the protein is described by the CHARMM force field, and allow them to reach success rates ranging from 56 to 78%. We have also developed a rapid binding free energy estimation approach, using SwissParam for ligands and CHARMM22/27 for proteins, which requires only a short minimization to reproduce the experimental binding free energy of 214 ligand-protein complexes involving 62 different proteins, with a standard error of 2.0 kcal mol(-1), and a correlation coefficient of 0.74. Together, these results demonstrate the relevance of using SwissParam topologies and parameters to describe small organic molecules in computer-aided drug design applications, together with a CHARMM22/27 description of the target protein. SwissParam is available free of charge for academic users at www.swissparam.ch.

Construcción de un índice de calidad ocupacional (ICO) para el análisis de la inserción profesional de los graduados universitarios = Building an employment quality index (EQI) to analyse graduates’ access to the labour market

En este trabajo se propone la construcción de un índice de calidad ocupacional (ICO) a partir de los datos de la Encuesta de Inserción Laboral de los Graduados de las Universidades Catalanas realizada por la Agencia para la Calidad del Sistema Universitario de Catalunya (AQU), que ha de permitir un mejor análisis de la información que proporciona la encuesta y facilitar su comparación con estudios similares. La encuesta se realiza tres años después de la graduación. En este artículo, se utiliza la segunda encuesta realizada el año 2005 entre 11.456 graduados (52,63%) de la promoción 2001 (AQU, 2005, Serra-Ramoneda, 2007). El índice se ha elaborado a partir de los indicadores objetivos ‘tipo y duración del contrato laboral’, ‘retribución económica’, ‘adecuación entre la formación universitaria y el empleo’ a los que se otorga una puntuación ponderada según las respuestas dadas por los graduados. La suma de las puntuaciones se matiza con un coeficiente derivado del indicador subjetivo ‘satisfacción con el trabajo en general’. A partir de la información proporcionada por el índice, se realiza un análisis comparativo del nivel de calidad ocupacional que han logrado los graduados de áreas de conocimiento, ámbitos de trabajo, ramas de actividad y ubicaciones territoriales del empleo diferentes. Los resultados obtenidos permiten observar que entre los graduados catalanes los siguientes hechos son buenos predictores de la calidad de la ocupación: haber estudiado una carrera que no sea de Humanidades, ser un hombre, haber desempeñado durante la carrera un trabajo relacionado con los estudios, estar ocupado en la construcción, en instituciones financieras o en servicios a empresas, haber tenido algún tipo de movilidad por motivos de trabajo, trabajar fuera de Cataluña y hacerlo en empresas grandes, especialmente con más de 500 trabajadores. Finalmente, se presentan algunas reflexiones y propuestas que pueden resultar de interés para la orientación de los estudiantes y la planificación universitaria

Living with invasive plants in the Anthropocene : the importance of understanding practice and experience

The role of humans in facilitating the rapid spread of plants at a scale that is considered invasive is one manifestation of the Anthropocene, now framed as a geological period in which humans are the dominant force in landscape transformation. Invasive plant management faces intensified challenges, and can no longer be viewed in terms of 'eradication' or 'restoration of original landscapes'. In this perspectives piece, we focus on the practice and experience of people engaged in invasive plant management, using examples from Australia and Canada. We show how managers 1) face several pragmatic trade-offs; 2) must reconcile diverse views, even within stakeholder groups; 3) must balance competing temporal scales; 4) encounter tensions with policy; and 5) face critical and under-acknowledged labour challenges. These themes show the variety of considerations based on which invasive plant managers make complex decisions about when, where, and how to intervene. Their widespread pragmatic acceptance of small, situated gains (as well as losses) combines with impressive long-term commitments to the task of invasives management. We suggest that the actual practice of weed management challenges those academic perspectives that still aspire to attain pristine nature.

L’extinction de l'extension juridique des conventions collectives dans le secteur manufacturier au Québec : le cas de l'industrie du vêtement

RÉSUMÉ Le gouvernement du Québec a adopté en novembre 1999 le projet de loi 47, relatif à la Loi concernant les conditions de travail dans certains secteurs de l’industrie du vêtement et modifiant la Loi sur les normes du travail (1999, c. 57). Son entrée en vigueur eut pour effet d’abroger au 30 juin 2000 les quatre (4) décrets sectoriels de convention collective qui régissaient les conditions d’emploi d’approximativement 23 000 travailleurs affectés à la production de vêtements (gant de cuir, chemise pour hommes et garçons, confection pour hommes et pour dames). Cette recherche démontre que bien qu’inscrit dans une logique étatique de dérégulation du travail visant à favoriser la compétitivité, le maintien de normes de substitution aux décrets dans le cas du vêtement québécois ne dérive pas pour autant d’une déréglementation strictement néolibérale. Au plan plus théorique, l’émergence et le sort du régime de conditions d’emploi étudié dévoilent la nature politique du processus d’élaboration des règles salariales, qu’il soit d’origine législative ou contractuelle. Cette dynamique repose sur le caractère mouvant des relations de pouvoir et d’influence des agents engagés dans la régulation institutionnelle, où l’État est appelé à jouer un rôle de catalyseur ─ et non de tiers arbitre indépendant ─ à l’endroit des tensions qui procèdent du rapport salarial et du mode de production au sein duquel il s’inscrit.

The Containment of Labour Unrest in the Post Socialist China

Due to its transition from the socialist mode of production to the capitalist mode, workers in China have been exposed to the exploitative class relations that they hardly experienced before. The working class is now assuming a subordinate position in the relations of production while the capitalist class remains in the dominant position. As a consequence, workers’ protests are constantly emerging and class conflicts are exacerbating in the contemporary China. I have set out to study in this paper how the party-state in China contains labour unrest through the All China Federation of Trade Unions (the ACFTU), which I argue is a state apparatus that performs the ideological, political and economic functions in different situations. There has been an ongoing academic debate on if the ACFTU is defending workers’ interests. Some scholars have expressed optimism while some have taken a dim view. Drawing on Poulantzas’ theory of capitalist state, I hope to make contribution to this debate by demonstrating that the ACFTU is under some circumstances serving the short term interests of workers as individuals, but not the economic and political interests of workers as a class. Instead of organizing workers to overcome the effects of isolation or forming a class for itself, the ACFTU attempts to contain labour unrest and reproduce their subordination in the relations of production.

Harmonic force fields from scaled SCF calculations: Program ASYM40

We report an extended version of our normal coordinate program ASYM40, which may be used to transform Cartesian force constants from ab initio calculations to a force field in nonredundant internal (symmetry) coordinates. When experimental data are available, scale factors for the theoretical force field may then be optimized by least-squares refinement. The alternative of refining an empirical force field to fit a wide variety of data, as with the previous version ASYM20, has been retained. We compare the results of least-squares refinement of the full harmonic force field with least-squares refinement of only the scale factors for an SCF calculated force field and conclude that the latter approach may be useful for large molecules where more sophisticated calculations are impractical. The refinement of scale factors for a theoretical force field is also useful when there are only limited spectroscopic data. The program will accept ab initio calculated force fields from any program that presents Cartesian force constants as output. The program is available through Quantum Chemistry Program Exchange.

Anharmonic force field of acetylene

The harmonic and anharmonic force field of acetylene has been determined in a least-squares calculation from recently determined data on the spectroscopic constants of various isotopic species (including the vibrational l-doubling constant). A general quadratic and cubic force field was used, but a constrained quartic force field containing only 8 of the 23 possible quartic constants. The results are discussed and compared with earlier work.
