This article investigates how fundamental labour rights specified in international framework agreements are implemented and monitored in subcontracting chains. It shows how labour's capacity for workplace‐based monitoring is influenced by factors such as ownership structures, the societal context, and, most importantly, the institutions and dynamics of local labour control.  相似文献

This paper considers rural land use by analysing stakeholder values and perceptions concerning various landscape components. The purpose is to show that landscape content and land cover interactions with societal connections should be a base for land use development. The practical goal is to deliberate research tools to quantify public opinions and attitudes, which could form bases for developing of decision support tools. The main research objectives are: (1) to assess existing opinions concerning land use changes and provide a clearer insight into public attitudes to the role of woodlands for an integrated development of the countryside; (2) to place ecological and socio-economic values on inanimate natural components of landscapes; and (3) to assess values and preferences held by land use policy and management experts regarding multiple landscape components and features to assist in decision-making. Through the different levels of importance (values) accorded by the respondents to the integration of nature components in rural landscapes public priorities were identified. The paper develops an understanding of why certain aspects of land use changes are unfavourably viewed by some people and favourably received by others. It suggests some innovative perspectives on the areas of consensus and conflict between people, providing initial information for the selection and evaluation of land use management decisions.  相似文献

The basis between spot and future prices will be affected by jump behavior in each asset price, challenging intraday hedging strategies. Using formal cojumping tests this paper considers the cojumping behavior of spot and futures prices in high frequency US Treasury data. Cojumping occurs most frequently at shorter maturities and higher sampling frequencies. We find that the probability of cojumping is altered by the presence of an anticipated macroeconomic news announcement. The probability of cojumping is particularly affected by news surprises in non-farm payrolls, CPI, GDP and retail sales. However, the two cojumping tests are also more likely to provide contradictory results in the presence of surprises in non-farm payrolls. On these occasions the market does not clearly signal its short term pricing behavior.  相似文献

We estimate that prenatal care has positive impacts on health measured at birth, shifts the distribution of future health care utilization away from inpatient care, and find that some of these impacts likely come from an informational mechanism. We also find well child visits are used in a complementary fashion with emergency department care in the production of infant health, suggesting that factors beyond barriers to access may drive the demand for emergency care. Finally, we find differential impacts of prenatal care across racial groups with evidence that the information mechanism may be particularly important for black mothers.  相似文献
