Screening for Alcohol Problems Among 4-Year Colleges and Universities

Abstract

Objective: To assess the use of alcohol screening tools across US colleges. Participants: Directors of health services at 333 four-year colleges. Methods: An online survey was conducted regarding the use of alcohol screening tools. Schools reporting use of formal tools were further described in terms of 4 tools (AUDIT, CUGE, CAPS, and RAPS) that the authors judged to be the most favorable based on prior empirical comparative studies. Results: Forty-four percent of colleges reported use of at least 1 formal alcohol screening tool and nearly all of these used a tool appropriate for college students. However, less than half of the 44% of colleges that used a screening tool used 1 of the 4 most favorable tools. Conclusions: Continued efforts are needed to encourage colleges to use the most effective available screening tools to identify alcohol-related problems that require intervention among students.     

论虚拟财产的继承

我国计算机网络发展起步较晚,但是发展的速度却十分惊人。在人们体验网络技术给生活带来的便捷、新鲜和娱乐的同时,新兴的网络事物正不断对现实生活中现有的维系正常秩序的规则发起挑战。即将来临的第一波网民老龄化高潮将虚拟财产的继承问题悄然推至网民面前,且在现实生活中已经出现了相关的诉讼,但这类诉讼纠纷却因为多方面的原因无法得到更为合理的解决,使得公民的合法权益不能得到有效保障。旨在研究虚拟财产这一伴随网络技术繁荣而出现的财产形式,将如何在继承领域得到合理的规范和保护。     

Implementing web-assisted learning and engaging academic staff in the change process

Abstract

In achieving the transition from a traditional taught mode of delivery to web-assisted learning, the management of universities now realise that change needs to be led and managed from the top down. They are also reliant on academic staff to engage in the change process. These two aspects are investigated in the context of a post-1992 university, which recently introduced a virtual learning environment (VLE) as part of a managed learning environment (MLE). Academic staff perceptions are explored within the framework of the 4-E model of staff engagement with technological change, but findings indicate a lack of evidence to support the 4-E balanced equation or likelihood-of-use factor.     

An Exploratory Study of Older Adults' Engagement with Virtual Volunteerism

Virtual volunteering refers to the use of the Internet for volunteer services. It is an emerging phenomenon among every age group; however, the current study examines if it is a viable option for older people. Older adults are the fastest growing Internet users. They are also more civic minded than younger generations, thus the purpose of this study is to explore this relatively new area research. Data for this study have been collected using qualitative tools such as semistructured, partly open-ended interviews with older virtual volunteers affiliated with SeniorNet, an organization that facilitates virtual volunteering exclusively for older people. The study ends with suggestions for future research directions. Implications of this study include reconceptualization of virtual volunteering as a strategic tool to recruit older adults and greater usage of information communication technologies to promote civic engagement among older people and, thus, positively influence their health and well-being.     

For the Love of Fluffy: Respecting,Protecting, and Empowering Transitional Objects in the Context of High-Conflict Divorce

ABSTRACT

Transitional objects are those idiosyncratically determined, beloved blankies and stuffed animals that communicate an absent parent’s affection. As such, transitional objects serve the short-term need to cope with separation, and the long-term need to move toward autonomy. This article discusses the value, use, and misuse of transitional objects in the context of coparental conflict. The concept of alienation-by-proxy is introduced. Specific recommendations are provided, including the therapeutic creation and empowerment of transitional objects to assist children experiencing separation anxiety, consideration of the role of transitional objects in child custody evaluations, and the court’s responsibility to encourage litigating parents to respect the child’s needs for transitional objects.     

社会化网络虚拟社区中的合作经济

数字革命的演化,催生了一个即时、互动的全球性社会化网络,随着其网络应用的流行,用户成倍增长,虚拟社区创造合作经济的商业价值也日益凸显.本文多方位引用了营销学和传播学的经典理论,辅之以近年来最新的案例,分别从消费者与消费者、企业与消费者、企业与意见领袖三个合作维度阐释了社会化网络虚拟社区中最具生命力的三种合作经济模式.     

虚拟社会的属性及其治理路径探析

虚拟社会作为现实社会在网络中的镜像,拥有虚拟实在性、匿名性、开放性、共享性、自律性等特性。其与现实社会既相区别又相联系,即它们在社会基础、社会关系和主体活动等方面有差异,但二者彼此互动统一于人类社会。基于此,我们认为,应从建立虚拟身份证明制度、构建虚拟伦理秩序、健全网络信息防护系统、完善舆情疏导机制等方面寻求治理路径。     

两阶段DEA前沿面投影问题研究——兼对我国上市银行运营绩效进行评价

DEA方法,即数据包络分析方法,是一种用于评价决策单元(Decision Making Units,DMUs)相对有效性的实证方法。近年来DEA方法已经广泛的应用于各行各业的绩效评价中,并发展出两阶段DEA方法。两阶段DEA方法相对于传统DEA方法的优势在于,它不但可以提供被评价对象的总体效率值,还可以分别生成每一阶段的效率值。但正是由于中间要素的存在,按照传统的DEA方法来调整两阶段DEA投入、产出要素的优化过程已不能成功投影在有效前沿面上。本文基于两阶段DEA方法,通过加入"虚拟中间要素"在两阶段DEA中嵌入一个"虚拟阶段",这样不但完善了两阶段DEA的逻辑结构,而且成功的将被评价单元投影到有效前沿面。最后本文应用以上方法对我国上市银行的运营绩效进行了实证分析。实证结果令我们意外的是,国有商业银行运营绩效优于股份制银行。     

性别价值观视野下的农村出生性别失衡原因的综合分析

出生婴儿性别失衡问题是一个关系到国计民生的重大人口社会问题,农村出生性别失衡更是如此。农村出生婴儿性别失衡的直接原因是性别选择性生育;根本原因是偏好男性的性别价值观。农民的性别价值观有其现实的合法基础:生产方式、养老方式、婚居方式、父系制度。调适农村出生婴儿性别失衡的现行政策措施存在三方面的问题:治标不治本;社会问题解决行政强制化;政策目标与生育者个体和家庭利益诉求相矛盾。因此遏制农村出生性别比失衡应坚持三原则:科学的态度;标本兼治;农民个人利益和家庭利益应纳入到政策的考量范围。
