环保要求与汽,柴油产品质量标准

经济发展带来的大气污染日趋严重,特别是在城市.大气污染的主要来源是机动车排气.为减少大气污染,仅着眼于机动车尾气处理是不够的,必须从污染源头即机动车所用燃料着手.因此,应该按照环境保护要求制定新的汽油和柴油产品质量标准.新的、环境友好汽油和柴油质量标准会对炼油工业的生产经营和技术开发产生重大影响.

Social protection for enhanced food security in sub-Saharan Africa

This paper identifies several positive synergies between social protection programmes and enhanced entitlements to food. One function of social protection is to manage or reduce vulnerability. Several instruments are reviewed – weather-indexed insurance, public works programmes, emergency food aid and buffer stock management – which aim to stabilise income and access to food across good and bad years, or between the harvest and the hungry season. Other social protection instruments aim to raise household income and crop production, for instance agricultural input subsidies or input trade fairs, as well as public works projects that construct or maintain physical infrastructure such as rural feeder roads. This paper also argues that entitlements to food can be strengthened if social justice principles are introduced to the design and delivery of social protection programmes. Examples reviewed include rights-based approaches such as employment guarantee schemes, community-based targeting and demand-driven accountability mechanisms. The paper concludes by arguing for a comprehensive approach to social protection that will achieve sustainable food security, by combining interventions that stabilise income or food production with those that raise income or food production, and are designed and delivered in ways that enhance social justice.     

Performance deviations and acquisition premiums: The impact of CEO celebrity on managerial risk‐taking

Research summary: This article draws on identity control theory and a study of acquisition premiums to explore how CEO celebrity status and financial performance relative to aspirations affect firm risk behavior. The study finds that celebrity CEOs tend to pay smaller premiums for target firms, but these tendencies change when prior firm performance deviates from the industry average returns, thereby leading these CEOs to pay higher premiums. The study also finds that the premiums tend to be even larger when celebrity CEOs have more recently attained celebrity status. Taken together, these findings contribute to identity control theory and CEO celebrity literatures by suggesting that celebrity status is a double‐edged sword and that the internalization of celebrity status by CEOs strongly influences the decision‐making of CEOs. Managerial summary: The purpose of this article is to examine how CEO celebrity status and financial performance relative to aspirations affect the size of acquisition premiums. The study finds that celebrity CEOs tend to pay smaller premiums for target firms. However, when celebrity CEOs' prior firm performance is either better or worse than the industry average, these CEOs pay higher premiums. This situation is exacerbated when the CEO has only recently been crowned a celebrity. In effect, these CEOs feel great pressure to match the inflated performance expectations that come with celebrity status. These findings suggest that being a celebrity is a double‐edged sword. The implication here is that CEOs who have recently been crowned a celebrity should be aware of these pressures and cope accordingly. Copyright © 2015 John Wiley & Sons, Ltd.     

天津景观水体富营养化综合评价

2009年9月对津河设置了13个取样点,进行采样,根据水体理化指标对津河水质状况进行了生物学评价,并依据总磷(TP)、总氮(TN)、透明度(SD)、高锰酸盐指数(CODMn)、叶绿素a(chla)综合评价水体的营养状态。结果表明,目前津河总氮、总磷、化学需氧量等主要指标均超标,整体处于重度富营养化状态。分析了津河富营养化的主要成因,并提出了保护津河水质的相关措施及建议。
