With enterprise values now representing increasing multiples of companies' net book assets, investors are clearly looking beyond financial reporting for enhanced insights and understanding of when and how companies are adding value. This shift includes growing attention to environmental, social, and governance (ESG) information. Although ESG data presents its own unique challenges, dismissing it as “non‐financial” can be misleading. When explicitly linked to a company's long‐term value creation strategy, ESG information can serve as a valuable input to more farsighted financial analysis. Market‐driven initiatives, notably that of the Sustainability Accounting Standards Board (SASB), aim to standardize a subset of business‐critical, industry‐specific sustainability data for investors. Research indicates such approaches can generate positive outcomes not only for providers of financial capital, but for their portfolio companies and markets in general. In illustrating these concepts, the authors explore ESG impacts in three sectors and industries, while examining how access to consistent, comparable, reliable sustainability information in those sectors can augment an analysis of traditional business fundamentals. One example focuses on water management in the Oil & Gas Exploration & Production industry, a major environmental issue where geographic considerations can shed light on company‐specific exposures to cost increases, production disruptions, increased CapEx and R&D spending, as well as the potential for asset write‐downs. In the Food & Beverage sector, health and nutrition concerns are shown to be changing consumer preferences, triggering regulatory action, and reshaping companies' product portfolios—with significant implications for the companies' brand values and ability to compete for market share. Finally, in Aerospace & Defense, lapses in business ethics such as bribery of government officials present a governance challenge that comes with the risk of value‐destroying fines and penalties and, even more significant, associated reductions in revenues. 相似文献

This article evaluates irrigated agriculture sector response and resultant economic impacts of climate change for a part of the Murray Darling Basin in Australia. A water balance model is used to predict reduced basin inflows for mild, moderate and severe climate change scenarios involving 1, 2 and 4°C warming, and predict 13, 38 and 63% reduced inflows. Impact on irrigated agricultural production and profitability are estimated with a mathematical programming model using a two‐stage approach that simultaneously estimates short and long‐run adjustments. The model accounts for a range of adaptive responses including: deficit irrigation, temporarily following of some areas, permanently reducing the irrigated area and changing the mix of crops. The results suggest that relatively low cost adaptation strategies are available for a moderate reduction in water availability and thus costs of such a reduction are likely to be relatively small. In more severe climate change scenarios greater costs are estimated. Adaptations predicted include a reduction in total area irrigated and investments in efficient irrigation. A shift away from perennial to annual crops is also predicted as the latter can be managed more profitably when water allocations in some years are very low. 相似文献

Childhood drowning remains a serious public health problem worldwide. The Australian Water Safety Council has set as one of its highest priorities the reduction of drowning deaths in children aged 0–14 years. However, concerns have recently been raised that many students completing primary school still lack the ability to recognize potential aquatic risks, cope with emergencies or assist someone else in danger. In this study, 107 primary school children aged 11–12 completed a one day training programme led by surf lifesaving instructors. Pre, post and eight week follow-up measures showed statistically significant improvements in recognition of the red ‘beach closed’ flag, aquatic safety signs, how to identify a rip current and choosing the safest place to swim at a beach that included a rip current in the picture. Following training students were more willing to provide first aid assistance to family members and friends in an emergency situation. Findings reinforce the value of school-based training that provides a general foundation for aquatic safety, with the caveat that current programmes must be evaluated to ensure their content has a robust prevention focus. 相似文献

This study measures the economic impact of the first phase of the Cocoa Livelihood Program (CLP‐I), a current World Cocoa Foundation (WCF) project, sponsored by the Bill and Melinda Gates Foundation and aimed at improving the livelihood of over 200,000 small cocoa producers in sub‐Saharan Africa via training, crop diversification, and farmer‐based organizations. Using data collected from 2,048 pre‐ and post‐CLP‐I interviews of cocoa producers in Ghana, Cote d'Ivoire, Nigeria, and Cameroon, the results show that yield enhancements attributable to CLP‐I are 32%, 34%, 50%, and 62% in Ghana, Côte d'Ivoire, Nigeria, and Cameroon, respectively. Using a total program cost of $151–$200 per beneficiary and estimated annual benefits of $109–$322 per beneficiary over 25 years, the benefit‐cost ratios are estimated to range from $18 to $62 for every dollar spent on human capital development. These results suggest the WCF should endeavor to increase the number of farmers who receive all, not some, of the components of the program. This would not only help ensure that each producer obtains as much human capital as possible from each of the training programs but increases the probability of reaching the CLP goal of doubling the income of cocoa‐growing households. 相似文献

Trade union education–a significant area of trade union activity – has been characterised by a tension between the desire to provide a certain ideological, economic and political perspective and the need to develop pragmatic bargaining skills. This comparative study examines the differing ways in which trade union education has developed in France and Britain. 相似文献

An effective emergency medical service (EMS) response to emergency medical calls during extreme weather events is a critical public service. Nearly all models for allocating EMS resources focus on normal operating conditions. However, public health risks become even more critical during extreme weather events, and hence, EMS systems must consider additional needs that arise during weather events to effectively respond to and treat patients. This paper seeks to characterize how the volume and nature of EMS calls are affected during extreme weather events with a particular focus on emergency preparedness. In contrast to other studies on disaster relief, where the focus is on delivery of temporary commodities, we focus on the delivery of routine emergency services during blizzards and hurricane evacuations. The dependence of emergency service quality on weather conditions is explored through a case study using real-world data from Hanover County, Virginia. The results suggest that whether it is snowing is significant in nearly all of the regression models. Variables associated with increased highway congestion, which become important during hurricane evacuations, are positively correlated with an increased call volume and the likelihood of high-risk calls. The analysis can aid public safety leaders in preparing for extreme weather events. 相似文献
