Obesity and Food Choices Among Faculty and Staff at a Large Urban University

Abstract

Objective: In order to address increasing health care costs associated with obesity, this study sought to determine prevalence of overweight and obesity and examine eating behaviors, food choices, health beliefs, and attitudes of university employees. Participants and Methods: An online survey was distributed to > 3,800 faculty and staff at a large public metropolitan university in Winter 2008. Results: Almost half (48%) of 806 respondents were classified as overweight or obese. Compared to those with normal weights, overweight and obese respondents consumed fewer fruits and vegetables (p < .05), were less confident in making healthful food choices (p < .001), and were more influenced by food choices available in on-campus dining facilities (p < .05). Conclusions: Obesity among university employees warrants attention. Because these employees have less self-efficacy and consume less healthful diets than their normal weight colleagues, universities need to improve on-campus access to healthful foods.

Adaptive PORT–MVRB estimation: an empirical comparison of two heuristic algorithms

In this article, we deal with an empirical comparison of two data-driven heuristic procedures of estimation of a positive extreme value index (EVI), working thus with heavy right tails. The semi-parametric EVI-estimators under consideration, the so-called peaks over random threshold (PORT)–minimum-variance reduced-bias (MVRB) EVI-estimators, are location and scale-invariant estimators, based on the PORT methodology applied to second-order MVRB EVI-estimators. Trivial adaptations of these algorithms make them work for a similar estimation of other parameters of extreme events, such as the Value-at-Risk at a level p, the expected shortfall and the probability of exceedance of a high level x, among others. Applications to simulated data sets and to real data sets in the field of finance are provided.     

高等教育强国实现途径的逻辑选择

国家与高等教育之间存在着内在关联,具有正相关性规律。高等教育与强国具有的正相关性规律体现在高等教育强国中高等教育系统是由高等教育自身发展规律与一个国家发展规律有机结合而形成的具有超活力、超能量的高等教育系统。高等教育强国实现途径的逻辑选择应是基于二者具有正相关性规律促进高等教育系统的强盛和完善,在建设高等教育强国过程中需要发挥政府、社会组织、大学的应有所为。     

论21世纪中国电影发展面临的问题和选择

进入21世纪以来,中国当代电影为自身创造了多种选择的空间,它的适应性与自我调节的能力越来越强。但电影政治、文化与商业在成为中国当代电影主要支撑维度的同时,也存在着严重的危机,面临着新的选择与发展问题。传记影片创作与英模人物表现联系到了一起,艺术向政治呈现出一种无原则的妥协。消费文化大行其道,电影承担了市场实践、创造时尚、情感宣泄等众多功能。但是,电影不能一味扮演商业先知、娱乐时尚等众多角色,也不能在商业主义、主流主义和作者主义之间自以为是地走钢丝。中式商业大片,受好莱坞“高概念”商业大片影响,类型丰富,强调视听奇观,具有电影想像力,而且叙述生动,人物形象鲜明,制作精良,有着比较强的影像张力。发展大片是基于国际市场竞争与华语电影快速发展的需要,是与电视剧市场、音像市场、网络市场等多媒体市场竞争的需要。     

西部承接东部地区产业转移的实证分析——以陕西省为例

欠发达地区积极主动地承接发达地区的产业转移,已成为其加快经济发展的重要途径.采用区域产业静态和动态集聚指数测算出东部地区五省一市具有转移趋势的产业和陕西省的区位优势产业,在此基础上确定出陕西省承接东部地区产业转移的对接行业.结果表明,东部五省一市目前劳动密集型产业对外转移趋势明显,陕西省的优势产业主要是重工业及资源型工业.陕西省应利用自己的产业基础和优势,找准产业承接的行业对接点.     

中国新生代农民工：社会态度和行为选择

20世纪80年代以后出生的“新生代农民工”现已达到约1亿人,成为中国社会转型过程中破除城乡二元结构、加快推动城镇化进程的关键人群。与“老一代农民工”相比,新生代农民工的价值取向和行为规则等已发生很大变化。本文基于中国社会科学院社会学所2008年“全国社会状况综合调查”数据,比较分析了新生代农民工的收入状况、受教育水平、工作技能、消费特征和地位认同,并重点分析了“代际”（新生代）和“阶层”（农民工）两个因素对新生代农民工的处境、行为取向和社会态度的影响,以及收入、生活压力和社会态度三者之间的关系。研究发现,生活压力的变化和个人权利意识的增强,对新生代农民工的社会态度和行为取向具有非常重要的影响。     

‘People with learning disabilities need a commissioner and a legal charter of rights’ – no they do not!

Since the UK Winterbourne View scandal, there have been a number of reports and responses recommending what should be done to ensure a similar scandal does not happen again. Two ideas have emerged which suggest that people with learning disabilities need a legal charter of rights and a commissioner to make a difference in their lives. This article, however, argues that although it is right that issues affecting people with learning disabilities are at the heart of discussion and debate, this does not take into account the complex, flexible and multiple identities of people with learning disabilities, and their knowledge, experiences and skills. This would be more beneficial in understanding the lives of people with the label of learning disabilities than a commissioner or a charter.

品牌、价格和原产地如何影响消费者的购买选择

运用联合分析方法探讨了品牌、价格和原产地在消费者购买决策中的相对影响. 两组消 费者,一组主要依据品牌影响力做购买选择,另一组则依据产品价格做购买决定. 对于后一组 消费者,更高而不是更低的价格具有更大的效用,表明价格被他们作为指示产品品质高低的线 索. 对两组消费者在个人背景和产品知识方面的差异作了比较,对研究结果的营销含义进行了 讨论.
