La globalización permeó las fronteras artificiales existentes entre la economía y la sociedad alrededor del mundo. Las actividades empresariales en este ambiente globalizado ha servido como catalizador de las violaciones de derechos humanos como consecuencia de la ausencia de la protección institucional algunas empresas han explotado los vacíos jurídicos y la falta de protección de los derechos humanos. Al respecto, para lograr un cambio paradigmático requiere un fuerte énfasis en los derechos y las obligaciones de las empresas. Este artículo presenta un análisis crítico de las obligaciones de las empresas en material de derechos humanos frente a la falta de cláusulas de estabilización en los contratos de inversión extranjera. En primer lugar, estas cláusulas son examinadas en relación con la responsabilidad en las obligaciones corporativas con relación a los derechos humanos fundamentales. De acuerdo con lo anterior, se analizan las dimensiones sustantivas y procesales de las cláusulas de estabilización. En segundo lugar, apelando a los ejemplos concretos del Acuerdo para el desarrollo de la Minería entre Mittal Steel y el Gobierno de Liberia, así como el proyecto del Oleoducto de Baku‐Tblisi‐Ceyhan como casos de análisis, este artículo busca la aplicación de las cláusulas de estabilidad en las inversiones extranjeras con relación a la protección de los derechos humanos por parte de los Estados y de las empresas. En tercer lugar, se propone una modificación a la forma como se introduce la cláusula relativa a los derechos humanos. En este orden de ideas, los derechos humanos de los inversionistas, específicamente de las empresas, deben ser incluidos en los acuerdos de inversión extranjera.

The themes of this paper are equality, reasonableness and gender rights in the dynamics of two sequential and convergent processes: the constitutionalization of judicial law, and the internationalization of constitutional law. The thesis of this paper is that in the face of non-compliance of the obligation to regulate, guarantee and protect gender rights, the best option has been to strengthen judicial law, which has enabled the development of rules for protection, the adoption of contemporary methods of interpretation and adjudication of the law, as well as the resolution of shortfalls in protection based on said processes of the constitutionalization and internationalization of local law.

The present study contributes to the literature on the Job Demands-resources model in the italian school context. the aim of this paper is to examine how the interaction between work-family conflict (i.e., a typical job demand) and opportunities to learn and to develop and self-efficacy (i.e., typical job and personal resources, respectively) affect the core dimensions of burnout (exhaustion and depersonalization) and work engagement (vigor and dedication). Hypotheses were tested with a cross-sectional design among 143 teachers of a junior high school in the north of Italy. Results of moderated multiple regression analysis partially supported the hypotheses as the opportunities to learn and to develop buffered against the aversive effects of work-family conflict on depersonalization, whereas self-efficacy moderated the relationship between work-family conflict and vigor. From a practical viewpoint, our findings suggest that opportunities to learn and to develop and self-efficacy are important re- sources that help teachers to reduce the negative effects related to work-family conflict.

La autora sostiene que, dadas las condiciones usualmente impuestas por los países industrializados acreedores, el pago de la deuda externa es inviable para el Ecuador. Si se consideran aspectos económicos, sociales yambientales, se puede apreciar que el actual servicio de la deuda genera una balanza de pagos insostenible, deterioro de la capacidad productiva local. aumento de la precariedad del mercado laboral, incremento de la extrema pobreza y una presión insoportable sobre los recursos naturales. Mediante un análisis de ciertos indicadores selectos, la autora establece las relaciones existentes entre el ajuste para servir a la deuda, el deterioro de las condiciones de vida, el impacto en la agricultura y los recursos naturales y la dinámica de los procesos migratorios.

In the northeastern United States, grassland birds regularly use agricultural fields as nesting habitat. However, birds that nest in these fields regularly experience nest failure as a result of agricultural practices, such as mowing and grazing. Therefore, information on both spatial and temporal patterns of habitat use is needed to effectively manage these species. We addressed these complex habitat use patterns by conducting point counts during three time intervals between May 21, 2002 and July 2, 2002 in agricultural fields across the Champlain Valley in Vermont and New York. Early in the breeding season, Bobolinks (Dolichonyx oryzivorus) used fields in which the landscape within 2500 m was dominated by open habitats. As mowing began, suitable habitat within 500 m became more important. Savannah Sparrows (Passerculus sandwichensis) initially used fields that contained a high proportion of suitable habitat within 500 m. After mowing, features of the field (i.e., size and amount of woody edge) became more important. Each species responded differently to mowing: Savannah Sparrows were equally abundant in mowed and uncut fields, whereas Bobolinks were more abundant in uncut fields. In agricultural areas in the Northeast, large areas (2000 ha) that are mostly nonforested and undeveloped should be targeted for conservation. Within large open areas, smaller patches (80 ha) should be maintained as high-quality, late-cut grassland habitat.

The kinetics of uptake of gaseous N2O5 on submicron aerosols containing NaCl and natural sea salt have been investigated in a flow reactor as a function of relative humidity (RH) in the range 30-80% at 295±2K and a total pressure of 1bar. The measured uptake coefficients, γ, were larger on the aerosols containing sea salt compared to those of pure NaCl, and in both cases increased with increasing RH. These observations are explained in terms of the variation in the size of the salt droplets, which leads to a limitation in the uptake rate into small particles. After correction for this effect the uptake coefficients are independent of relative humidity, and agree with those measured previously on larger droplets. A value of γ=0.025 is recommended for the reactive uptake coefficient for N2O5 on deliquesced sea salt droplets at 298K and RH>40%.

Agricultural management of grassland in lowland Britain has changed fundamentally in the last 50 years, resulting in spatial and structural uniformity within the pastoral landscape. The full extent to which these changes may have reduced the suitability of grassland as foraging habitat for birds is unknown. This study investigated the mechanisms by which these changes have impacted on birds and their food supplies. We quantified field use by birds in summer and winter in two grassland areas of lowland England (Devon and Buckinghamshire) over 3 years, relating bird occurrence to the management, sward structure and seed and invertebrate food resources of individual fields. Management intensity was defined in terms of annual nitrogen input. There was no consistent effect of management intensity on total seed head production, although those of grasses generally increased with inputs while forbs were rare throughout. Relationships between management intensity and abundance of soil and epigeal invertebrates were complex. Soil beetle larvae were consistently lower in abundance, and surface-active beetle larvae counts consistently higher, in intensively managed fields. Foliar invertebrates showed more consistent negatively relationships with management intensity. Most bird species occurred at low densities. There were consistent relationships across regions and years between the occurrence of birds and measures of field management. In winter, there was a tendency towards higher occupancy of intensively managed fields by species feeding on soil invertebrates. In summer, there were few such relationships, although many species avoided fields with tall swards. Use of fields by birds was generally not related to measures of seed or invertebrate food abundance. While granivorous species were perhaps too rare to detect a relationship, in insectivores the strong negative relationships (in summer) with sward height suggested that access to food may be the critical factor. While it appears that intensification of grassland management has been deleterious to the summer food resources of insectivorous birds that use insects living within the grass sward, intensification may have been beneficial to several species in winter through the enhancement of soil invertebrates. Synthesis and applications. We suggest that attempts to restore habitat quality for birds in grassland landscapes need to create a range of management intensities and sward structures at the field and farm scales. A greater understanding of methods to enhance prey accessibility, as well as abundance, for insectivorous birds is required.
