Water stewardship and corporate sustainability: a case study of reputation management in the food and drinks industry 下载免费PDF全文
The aim of this paper is to provide an exploratory review of the extent to which some of the leading companies in the food and drinks industry are publicly addressing water stewardship as part of their corporate sustainability strategies. The paper begins with an introductory outline of the growing importance of water stewardship and a brief discussion of corporate sustainability. The paper draws its empirical material from the most recent information on water stewardship posted by the leading companies in the food and drinks industry's corporate websites. The findings reveal that the vast majority of the selected companies address a number of elements concerning water stewardship as part of their more general approach to corporate sustainability. However, corporate commitments to water stewardship can be interpreted as being driven as much by business imperatives as by any specific concerns for environmental sustainability or a genuine desire to maintain the viability and integrity of natural ecosystems. More critically, the authors suggest that the selected companies' commitments to water stewardship are framed within existing business models focused on technological improvements in eco‐efficiency and continuing economic growth. The paper provides an accessible review of the water stewardship issues being pursued by the leading players in the food and drinks industry, and as such, it will interest academics, students, political commentators and business managers interested in water stewardship and corporate sustainability.

Over time, many fields of work - law, medicine, and teaching - matured from informal bodies of knowledge and skills, passed from one practitioner to another, into professions. In the process each began enumerating and affirming their intellectual and practical roots. Each also began testing practitioners to insure comprehension of relevant knowledge and an ability to demonstrate relevant skills. Family mediators in Canada have moved in this direction. In the United States, people who mediate interpersonal disputes also feel pressured to take additional steps to assure the quality of our work. This article summarizes what mediation organizations in the United States have done and could do to vouch for work in our field. But, taking additional steps calls for a clearer understanding of what a mediator should know and what they are expected to do. These two critical pieces of information remain nebulous. So, this article goes beyond describing ways of insuring accountability by also describing a recently completed job analysis, a tool frequently used in other fields of work to describe the skills and knowledge relevant to a particular job. 相似文献

Excretion of alcohol in urine and diuresis in healthy men in relation to their age, the dose administered and the time after drinking 总被引:1,自引:0,他引:1
A W Jones 《Forensic science international》1990,45(3):217-224
Healthy male volunteers drank neat whisky in amounts corresponding to 0.51, 0.68, or 0.85 g ethanol/kg body weight in 15-25 min after an overnight (10 h) fast. Urine was collected immediately before drinking and then at 60 min intervals for 7-8 h after intake. The volumes of urine voided were measured and the concentrations of alcohol (UAC) were determined by an enzymatic method. Ethanol-induced diuresis showed large inter-subject variations. The flow of urine was maximum between 60 and 120 min post-drinking when the median rates of production were 117 ml/h (range 55-335), 113 ml/h (range 41-453) and 373 ml/h (range 215-485) for 0.51, 0.68, and 0.85 g ethanol/kg respectively. The output of urine returned to normal (30-60 ml/h) after the peak UAC had passed despite an elevated blood alcohol concentration (BAC). The average amount of alcohol excreted in urine was 0.29 g (S.D. 0.119), 0.44 g (S.D. 0.246), and 1.00 g (S.D. 0.427) after the consumption of 0.51, 0.68 and 0.85 g ethanol/kg respectively. Neither peak diuresis nor the amount of alcohol excreted depended on a subject's age between 20 and 60 years. This work shows that after drinking a moderate dose of alcohol, only 0.7-1.5% of the amount consumed is excreted unchanged in urine. Ethanol-induced diuresis is most pronounced for the first 1-2 h after drinking (rising BAC). The production of urine returns to normal during the post-absorptive state. 相似文献
