The Representation of Altruistic and Egoistic Motivations in Popular Music over 60 Years

Content analyses examining the values expressed in popular music have been predominantly ad hoc, limited to antisocial themes, and lacking a comprehensive theoretical coding scheme. We applied a content analytic scheme based in the model of intuitive morality and exemplars (MIME) to examine altruistic and egoistic values in popular music over 60 years. Findings show (a) more frequent representation of egoistic than altruistic motivations, and (b) the profusion of egoistic motivations focused mostly on romantic (in adult-targeted music) but also platonic (in child-targeted music) relationships.     

Bridging the real and ideal: A comparison between learning community characteristics and a school-based case study

While a growing body of literature advocates the importance of school-based, collaborative action research, less attention has been focused on how these projects are developed and implemented in the early stages. This study, therefore, examines a small Canadian school's initial attempt at promoting a “learning community” approach and compares it to the ideals of collaborative teamwork set out by recent scholarship. Our findings suggest that collegiality holds promise for change in teachers' practice and meaningful professional development if the school's administrator accepts the learning community philosophy and is willing to take the lead in initiating the reform. As well, we found that all ideal characteristics set out in the literature need not be in place from the outset for a project of this sort to be successful.     

用内核级的噪声注入来刻画应用程序对操作系统干扰的敏感性

操作系统噪声是限制应用程序可扩展性的主要因素。很多研究试图采用用户层的机制来量化噪声的来源和影响。本篇论文描述了一种基于内核的噪声注入机制，并重点研究应用程序对各种噪声模式的敏感性。我们介绍了在Catamount轻载内核上噪声注入框架的实现，并展示了当节点数达到上万个时系统对应用程序产生的各类影响。我们的研究结果证明了噪声（不同频率和持续时间）产生原因的重要性，     

THE COMMUNITY‐JUNIOR COLLEGE AND ITS ECONOMIC VALUE: A 3‐YEAR STUDY

As local governments tighten their budgets, community‐junior colleges are often caught in the squeeze. Economic impact studies are often appropriate to help explain the monetary benefits of a local community‐junior college. Temple Junior College evaluated its impact on the local Temple, Texas, economy over a 3‐year period. The results have been used as a meaningful public relations tool that has allowed the administration to explain the value of the college in quantitative terms.
