2007年美国爆发的次贷危机,通过关国体系的贸易及投资传染链条,在影响全球经济的同时,也带来了人们对传统金融价值观的反思,迫使人们重新审视虚拟经济与实体经济、金融创新与金融稳定、混业经营与分业经营、自由放任与政府干预的关系。此外,金融危机的全球蔓延也考量了国际金融版图的稳定性,并给发展中国家(地区)带来了前所未有的挑战和机遇。  相似文献

This article examines the exit and survival dynamics of burley tobacco growers in Tennessee, North Carolina, and Virginia using a discrete‐time hazard logit model. The study also predicts the effects of selected farm and family characteristics on exit hazards, assesses the proportionality of their effects over time and their relative importance in explaining the variation in exit hazards among burley tobacco growers. Results provide the longitudinal progression of the probability of exiting the tobacco industry since the end of the federal tobacco program in 2004, and identify off‐farm participation, percentage of farm receipts from tobacco, tobacco price, educational level, and farm size as the most important determinants of the decision to exit the tobacco industry. Further, the effects of off‐farm participation and farm size on the exit hazards of burley tobacco farms are proportional over time while the effects of the percentage of farm receipts from tobacco and tobacco price are time variant.  相似文献

ABSTRACT

This study aimed at examining different segments of visitors to Tanzania with respect to their values around sustainability. Using a self-administered questionnaire, 286 cases were analyzed through a combination of non-hierarchical and hierarchical cluster analyses. The results indicated three clusters of visitors, each with different sustainable values. A follow-up analysis using ANOVA and Chi-square indicates the three clusters are significantly different in their sustainable values, their travel motives, and their demographics. These results provide insights for both public and private organizations on how to market and manage different destination elements to visitors in a sustainable manner.  相似文献

This paper examines three of the primary structures of thought and some of the situational circumstances that enable and constrain the actions of corporate leaders in the airlines industry. It argues that lawyers and corporate leaders who understand the law and the structures of power in America have a unique capacity to protect and enhance share-owner wealth. Three examples are used to propose a model of force relations in complex, high-stakes situations.  相似文献

对保险条款的解释歧义是发生保险合同纠纷的常见原因。新《保险法》第30条对适用有利于被保险人和受益人解释的条件和范围作了限制性规定。司法实践中,裁判机关对保险条款的解释应当坚持以通常解释为前提、意思解释与表意解释兼顾、附加非格式条款优先、有利保险相对人解释四项基本原则。  相似文献

世界旅游产业的规模不断壮大,但旅游业在带来经济增长的同时产生很多文化和社会问题。文章认为,要深化这一问题的研究,不能单独发展旅游业,应在文化自觉的基础上,基于文化本身价值,结合当地的需求,有选择地进行多种产业的互补开发,尤其是文化创意产业,促进当地人的文化自觉和对传统文化的创新,形成良性循环,最终促进文化效益、社会效益、经济效益的协调发展。在实践经验和理论分析的基础上,本文试图构建多种产业发展和文化自觉良性循环的模型。  相似文献

近年来,我国海洋经济统计在不断拓展范围、补充内容、疏通渠道、提高效率,而实际统计中数据质量控制工作仍较为滞后,存在审核方法简单、效率低、范围窄等不足。本文阐述了海洋经济统计数据质量控制内涵,即包括数据的完整性、准确性、可比性、有效性,并结合海洋经济统计调查工作相关实践数据,研究了基础性检验、逻辑性检验、值域范围检验、数理统计检验等主要质量控制方法在数据审核工作中的应用,并进行了案例分析。本研究解决了海洋经济统计数据质量审查与控制的一部分难题,以期为调查实践部门开展数据质量控制工作提供具有可操作性的参考依据,并不断推动海洋经济统计数据质量控制工作走上规范化、科学化。  相似文献

The college town of State College, PA, USA is home to The Pennsylvania State University (PSU) and its many facilities. Our initial research interest was to understand the influence of the newly developed Arboretum at Penn State (APSU) on nearby housing values in State College over time. Current sales transaction data were gathered and a pooled cross-sectional regression analysis approach utilized. Contrary to the literature, our findings suggest proximity to APSU, as well as three other nearby open spaces, had no significant influence on nearby homes. Further, proximity to PSU’s main campus was negatively associated with housing values. Neither of these patterns varied over time.To further explore these results, the study area was expanded beyond the neighborhoods most proximate to APSU to the balance of the borough. These results replicated our earlier findings, confirming that living close to PSU’s campus is negatively associated with housing values community-wide. These findings disconfirm the common practical assumption that the State College market places a premium on proximity to the town’s major employment center (PSU campus) and a significant local landmark (APSU). Housing markets in similar college towns may not reflect typical residential areas and may require alternative evaluation considerations.  相似文献

In this study, we sought to identify the use and non-use values that underlie farmers’ decision making with respect to animal welfare, based on in-depth interviews with 50 dairy farmers in Sweden. We identified use values related to: being able to continue the business, earning a living from the business, not being tied to the farm (i.e. having time available for other things), product quality, and work environment. We also identified non-use values related to avoidance of suffering, being able to further improve the welfare of dairy cows, the dairy farmer feeling good him/herself, ethical considerations, a feeling of doing the right thing, and animals eating properly (i.e. functioning as dairy cows should). Understanding the values underlying dairy farmers’ decision making with respect to animal welfare is an important step in understanding why these farmers work with animal welfare. The results are useful in improving communications from authorities and farm advisors to farmers, as a strategy to gain better acceptance for improved animal welfare standards; in designing product certification schemes in the food industry; and in communicating to the public the values influencing production of dairy products.  相似文献
