面向供应链融资的企业无风险收益合约研究

摘要：供应链融资服务是一种新型的银行金融产品服务,是实现中小企业资金市场化的有效切入点。本文根据供应链融资运作中企业间的合作关系,建立了不同主体无风险合约模型。基于此模型,研究了银行和企业对贷款额度与利率的承受范围,分析了供应链融资参与主体间的无风险合约达成条件,提出了企业努力水平与贷款利率、贷款额度之间的激励关系。研究表明,供应链项目未来收益作为银行还款来源不仅与项目自然状态有关,还有与成员企业努力水平有着直接的关系,只有成员企业共同努力,才能保证供应链整体效益最大化,从而才能实现企业自身收益最大化。

CEO特征、风险偏好与企业研发支出——以技术密集型产业为例

本文以我国技术密集型产业的上市公司为样本,对CEO特征、风险偏好与研发支出之间的关系进行了实证分析.研究发现:CEO风险偏好受到CEO任职期限与教育背景的影响;而CEO风险偏好与企业研发支出之间呈显著正相关关系;风险偏好在CEO个人特征与企业研发支出之间起中介作用.因此,根据企业特点选择具有适当教育背景的管理者、合理安排管理者的任期将有利于提高企业的研发支出.     

高校学术不端行为四维度影响机理实证研究

 学术不端行为破坏了高校学术研究的有序发展,探寻其影响因子及敏感性有重要的现实意义。运用结构方程模型研究了个人压力、个人素质、组织制止和环境支持四个维度对成果内容型不端和社会关系型不端的影响机理。结果发现两类不端行为的影响因子及其力度有所不同,个人素质对两类学术不端行为均存在负向影响力,且影响力度均为最大,个人压力对两类学术不端行为均存在正向影响力,环境支持对社会关系型不端行为有显著的正向影响力,组织制止对成果内容型不端行为有较显著的负向影响力。据此,应注重提升高校科研人员的学术诚信素质,制定可操作的学术规范,建立适度的组织惩戒和社会惩戒制度,并努力创建宽松的学术研究氛围。     

松嫩平原土壤有机质含量高光谱反演研究

采集松嫩平原典型类型土壤样本252个.室内条件下测定了风干后土样的光谱.对原始光谱数据作预处理后,分别运用多元线性逐步回归法和偏最小二乘法建立土壤有机质含量高光谱预测模型.结果表明,采用2种方法建立的模型均可满足有机质含量速测要求,但偏最小二乘法得到的模型更具稳健性.

Fear and Loathing in the Fog: The Perceived (and Persistent) Vagaries of Tenure Standards Among Mass Communication Professors

Perhaps nothing strikes more fear into the hearts of all tenure-track professors than the process itself. Are four papers in this journal good enough? Are eight papers in another okay? What if someone doesn’t like me or my area of research? These issues have plagued academia since the first essay was penned by the first researcher hundreds of years ago. While personal bias and journal preference continue to infect honest tenure reviews, solutions exist. This does not mean we have a magic bullet to solve issues of bullying or elitism. However, if we are honest in our desire to improve the Academy, we should avail ourselves of every possible tool for improvement. This essay is based on a survey sent to 2,500 mass communication educators. Of the almost 500 respondents, roughly 10% took the time to express emotions that ranged from fear and confusion to outright rage and anger, all because what ought to be clear is not. The author offers 10 ideas of how academia can improve its evaluation of new faculty, as well as a few suggestions regarding the unnecessary inclusion of personal issues in a process that ought to be about creating better researchers and teachers.     

The Rise of Global Publishing and the Fall of the Dream of the Global Book: The Editing of Peter Carey

The article documents the editorial relationship between Peter Carey and his New York based editor for Knopf, Gary Fisketjon, who worked with Carey on his True History of the Kelly Gang. This account provides the basis for a discussion of how globalised publishing, while promising unity—a single text across all territories—has instead introduced a tension into the previously cohesive triad of author, editor, and the single authorized text. As Fisketjon’s experience lays bare, major contemporary texts that are published in multiple editions in different global centers may well proceed through competing or at least parallel editing processes with different presses, different editors, and in different publishing territories. The authorized single edition, even of major literary texts, has been replaced by competing editions. The single edit and editor have been replaced by competing “servant[s] of the writer” (to use Fisketjon’s phrase). Cohesion, while not quite giving way to disunity, gives way to multiplicity and plurality. The experience of the Kelly Gang book is cast against a longer narrative of Carey’s interactions with editors including the University of Queensland Press (UQP) from the 1970s and Faber from the 1980s.     

Student Attitudes and Behaviors Towards Digital Textbooks

The purpose of this article is to add to the collective body of knowledge on student behavior and attitudes relative to the adoption of digital textbooks. The article summarizes an ongoing research project that examines past, current and evolving behavior in the classroom related to digital textbooks and school. It includes students, faculty and administrative attitudes behaviors and perceptions. This research was undertaken at the Sawyer Business School of Suffolk University in Boston, Massachusetts. Student attitudes and behavior toward their use of digital textbooks (eTextbooks) in higher education was examined in an ongoing longitudinal study over two years at Sawyer Business School, Suffolk University. Students in the class were divided into six teams. Five of the teams were assigned an eTextbook device and the sixth team was given a paper textbook for use through the semester. The digital technologies examined were: Amazon Kindle, Sony eReader Touch, Apple iPad, enTourage eDGe, and CourseSmart. Student attitudes and behaviors were examined pre and post class by survey each semester, and during the semesters through quizzes, journals and classroom discussion. Differential learning was measured between the six teams. Student attitudes and behaviors are becoming more receptive to and accepting of using digital textbooks each year. There was no significant difference in learning between the eTextbook devices teams or between them and the paper textbook team.
