This research aims at assessing the environmental impact of the poultry supply chain from cradle to grave using case study research and also life cycle assessment (LCA). While a limited number of generic poultry production LCA studies have been published, fewer yet assess the whole process of a specific organisation, none comparing the increased impact of further processing. Our results show that irrespectively of the impact assessment method utilised, the process of producing portions is considerably higher in total environmental impact due to the extra raw material required to produce the same mass into retail. Our research contributes to the growing number of LCA studies and could be used by practitioners for comparison against national and international averages. From a theoretical point of view, this research provides new insights into the relationship between vertically integrated supply chains and environmental performance which has not been examined in the past.  相似文献

Accounting for convertible debt has long been a source of controversy in the accounting profession in the U.S. Current U.S. accounting rules require classifying convertible debt at date of issuance as "entirely debt" until conversion, despite numerous studies that assert that convertible debt is not "entirely debt", but is a blend of debt and equity. Convertible debt has taken on international interest because of the issuance of International Accounting Standard (IAS) 32, Financial Instruments; Disclosure and Presentation, which prescribes reporting separate debt and equity components for convertible debt. This study examines convertible debt issued by U.S. firms and non-U.S. firms listed in the U.S. using a levels approach. Specifically, convertible debt is compared to straight debt and contrary to ex ante expectation, convertible debt was not found to be perceived as being significantly different than straight debt for U.S. firms for any years and is statistically different in only two of the six years tested for non-U.S. firms. The validity of this study's findings is underscored by its research design, which compares convertible debt and straight debt issued by the same firms. The findings suggest that investors regard reported amounts of convertible debt similar to straight debt in their assessment of firm value.  相似文献

This paper uses detailed industry level time-series data for the UK regions which suggests that convergence (at least in terms of output-per-employee) was not occurring during the period 1968–92. Based on testing for unit roots, it is found that in a majority of industries and regions growth was divergent, and consequently there is little empirical support for the neoclassical 'long‐run catch up' model.  相似文献

Recognizing the immense purchasing power of children, marketing researchers often gather information from them. Given the vulnerability of these children as research subjects, this paper explores the different ethical standards that marketing researchers could adopt in their research efforts. The Paternalistic Ethical Standard and the Limited Paternalistic Ethical Standard are discussed and the ethical quandary known as the Pontius Pilate Plight is identified in the context of the latter standard. An enhanced version of the Limited Paternalistic Standard is suggested as an ethical guide for marketing researchers. Based on interviews with professional marketing researchers to gauge the applicability of the proposed standard, managerial implications are identified.  相似文献

Under Thatcher the United Kingdom introduced a major program of labour market deregulation, claimed to have made the United Kingdom one of the least regulated labour markets in the OECD. This paper reviews the measures implemented and assesses their impact. Trade union membership declined steeply, and collective bargaining was curtailed even more sharply. The impact of the legislation curbing unions can be exaggerated, given that it coincided with wider developments. At the microeconomic level there is some evidence that the decline of unions contributed to productivity gains, but no clear evidence on employment, investment, profitability or wage premia. UK macroeconomic performance improved, but not dramatically. The most marked features of the more flexible labour markets are the growth of part-time and temporary work, while job insecurity has become a common perception. The most striking development is the growth in earnings inequality, in part reflecting the weakening of collective bargaining. The evolution and consequences of inequality will be a major criterion in assessing the moves to labour market flexibility.  相似文献
