研究生教育的国际经验及对我国的启示

对美国的分类有针对性的研究生教育、日本产学研结合的研究生培养以及俄罗斯严谨的研究生教育进行了论述。指出我国的研究生应按学术型与专业型分类,在研究生的招生与培养上应按该两种类别区别对待,学术型研究生的培养应注重学生的选拔与指导,专业型研究生的培养要特别加强学校与企业的联合培养。     

学术团队内在价值意义共享水平与知识创新能力水平之间的关系

分析了学术团队内在价值意义共享水平与知识创新能力水平之间的关系,以及内在价值意义共享水平的前因变量,并利用调研数据进行了验证性研究。结果显示:团队内在价值意义共享水平是直接影响学术团队知识创新能力水平的重要变量,团队文化和团队激励机制是影响学术团队内在价值意义共享水平的重要因素。     

土地征收中限制条件与公共利益评估

土地征收中公共利益的判断应该遵从权利制衡原则、公开透明原则与扩大参与原则;其公共利益的具体判断标准有:受益对象的多少;向社会公众提供公共产品;满足国家的经济、文化、国防等建设目标;土地征收的结果确实能使社会公众受益。由于土地征收行为对被征收人的重大影响,应对土地征收的公共利益进行必要的限制。     

对普通高校学风建设的思考

高等教育大众化使普通高校的学风建设更显重要。高校必须营建一个有利于学生学习和成长的环境氛围 ,主要的是要加强教师教风的建设、学生学风的建设和学术气氛的创建 ,努力培养出适应社会发展和需要的高质量人才。     

To each according to their ability? Academic ranking and salary inequality across public colleges and universities

This article compares the salary structure of tenured and tenure-track faculty across schools within the university systems of North Carolina and New York. Specifically, we establish a positive relationship between school prestige and salary inequality, both overall and within specific academic ranks. This result suggests that the value to teaching is less discipline-specific than the value to research output. Marked differences in the aforementioned statistical linkage across academic ranks also confirm prior speculation that junior faculty salaries are more closely tied to academic value than senior faculty salaries.     

土地复垦监管行为规范的主体性合作治理形式选择

研究目的:根据相关主体性意愿的指引,阐明合作治理范式在土地复垦监管行为领域展开具体运用的现实性,及其可能的规范设定方向,进而尝试在相应行为规范维度来检视行政行为法理论的发展任务命题。研究方法:文献分析法。研究结果:土地复垦监管行为的形式选择往往与相应的合作治理主体性意愿有关,该意愿主要表征为利益导向、工具载体以及协同组织选择意愿。应厘清该类选择意愿指引于土地复垦监管行为规范所分别呈现的形式选择:逐利心态与信任习惯选择、科学事实工具与行政规制工具选择、内部协同组织与外部协同组织选择。研究结论:土地复垦监管行为在行为观念和当事人方面与合作治理的主体性意愿在一定程度上是相互耦合的,有必要构建一种合作行政模式下的治理型土地复垦监管行为规范。     

Research collaboration model in academic social networks

ABSTRACT

This paper proposes a hybrid collaboration recommendation method that accounts for research similarities and the previous research cooperation network. Research cooperation is measured by combining the collaboration time and the number of co-authors who already collaborated with at least one scientist. Research similarity is based on authors’ previous publications and academic events they attended. A weighted directed graph is built to discover new collaborators by using direct and indirect connections between scientists. Moreover, a consensus-based system is built to integrate bibliography data from different sources. The experimental results show that our method improves the recommendation performances over other methods.     

The Influences of Portion Size,Context and Package Characteristics on Snack Food Consumption: Evidence from a U.S. Rolling Cross-Sectional Survey

Using a rolling cross-sectional sample of over 40,000 U.S. snack food consumers during 2004–2010, we build a three-dimensional model to study how portion sizes, consumption context, and package characteristics jointly affect the amount of food consumed. As with prior research, we find that consumption does increase with larger portions. However, this effect diminishes significantly when accounting for the consumption context and packaging characteristics as consumption drivers. Most important is how the snack is presented to consumers at the point of consumption (type, size, and quantity of packages). We also find that snacking on impulse, alone, with a beverage, or while watching television increases the amount consumed, whereas socializing or snacking at home decrease consumption. We test our model over seven snack types (potato chips, crackers, cheese puffs, nuts and seeds, tortilla chips, pretzels, popcorn), and find that our results hold even for products with different cross-category granularity, palatability, and satiety.     

To tell or not to tell? The roles of perceived norms and self‐consciousness in understanding consumers' willingness to recommend online secondhand apparel shopping

Secondhand apparel shopping resides in a domain characterized by used goods traditionally associated with financially marginalized consumers. Acknowledging the elusive psychological barriers associated with preowned apparel, this study explores mechanisms that facilitate consumers' willingness to recommend online secondhand apparel shopping. Results from three experimental studies and a cross‐sectional survey of online secondhand shoppers in the United States reveal that hedonic and ethical benefits influence recommendation behavior via perceived norms, whereas economic benefit directly influences consumers' willingness to recommend. Moderated mediation analyses further demonstrate that self‐consciousness alters the strength of the indirect effects, such that consumers with lower self‐consciousness displayed greater willingness to recommend compared to highly self‐conscious consumers. Findings contribute to a greater theoretical understanding of the roles perceived norms and self‐consciousness play in facilitating or inhibiting recommendation behavior in a context that implicitly involves self‐disclosure of one's secondhand purchase behavior. Managerial implications offer insights on salient benefits that can be leveraged to influence word‐of‐mouth recommendation.
