“I know it’s not your job but…”: Extra-role tasks,communication, and leader-member exchange relationships

Employees are sometimes assigned tasks that lie outside their official role. Employees may perceive such extra-role tasks (ERTs) as unreasonable or illegitimate. Grounded in role theory and leader-member exchange (LMX) theory, we conducted two studies that examined how ERTs are associated with supervisor-employee relationship quality and how the ERT assignment is communicated. While supervisor-subordinate relationship quality was unrelated to the likelihood and frequency with which supervisors assign ERTs to employees, employees with low-quality relationships evaluated ERTs as more unreasonable than those in high-quality relationships. Study 1 showed that ERT messages that included a request (vs. command), acknowledgement, explanation, and appreciation were associated with higher quality LMX relationships. Study 2 found that ERT message characteristics influenced the perceived unreasonableness of the task for employees in high-quality relationships, suggesting employees in such relationships are particularly vulnerable to “job creep” and role expansion.     

On the shortcomings of our organisational forms: with implications for educational change and school improvement

This article informs school improvement and educational change from a radically different perspective. Building upon work done recently in neural psychology, primatology and ethology, the article examines four common and general types of organisational form: the cell, the silo, the pyramidal, and the network types of organisational structures. Status and dominance hierarchies are discussed, as are the dynamics of collaboration/competition and collectivism/individualism. Final consideration is given to the concepts of culture and community, especially as they manifest in the school improvement literature.     

Concerns about the Disproportionate Use of Economic Research in the FCC'S Media Ownership Studies from 2002–2007

An analysis of the studies used by the U.S. Federal Communications Commission (FCC) in its media ownership proceedings from 2002–2007 found a disproportionate use of economic research to support the agency's rule changes. The use of this research in policymaking is important because the FCC's reliance on economic literature may have helped justify a “procedural” definition of what constitutes the public interest, and a “neoliberal” faith in the wisdom of market forces to ensure that the public interest is being served. The findings suggest that the inclusion of a broader range of scholarship, especially media research, would not have supported the FCC's decision to further relax media ownership rules.     

Preparing the “New” Biologist of the Future: Student Research at the Interface of Mathematics and Biology

We describe a unique Research Experience for Undergraduates and Research Experience for Veterinary students summer program at the National Institute for Mathematical and Biological Synthesis on the campus of the University of Tennessee, Knoxville. The program focused on interdisciplinary research at the interface of biology and mathematics. Participants were selected to work on projects with a biology mentor and a mathematics mentor in an environment that promoted collaboration outside of the students'' respective disciplines. There were four research projects with teams of four participants and two faculty mentors. The participants consisted of a mixture of 10 undergraduates in biology- and mathematics-related disciplines, four veterinary students, and two high-school teachers. The activities included lectures on both the biological and mathematical backgrounds of the projects, tutorials for software, and sessions on ethics, graduate school, and possible career paths for individuals interested in biology and mathematics. The program was designed to give students the ability to actively participate in the scientific research process by working on a project, writing up their results in a final report, and presenting their work orally. We report on the results of our evaluation surveys of the participants.     

"潜藏在华丽的异域外表之下的是什么":桑顿的中国风

2002年由海伦·克拉克总理就1881年华人移民法案及其他带有歧视性的法规,向新西兰华人社会做出了正式的政府道歉;这一事件使公众舆论集中到对早期新西兰社会的一大特征,即持久而强烈的“恐华症”的关注之上。与之相反但程度同样强烈的“亲华症”,虽也是殖民社会各组成部分的显著特征,却较少有人提及,具体来说就是指时尚风潮对奇异情趣的“中式”装饰艺术的追求,通常被称为中国风。这些“中式”物品沉默不言但却又雄辩滔滔的外观,能帮助我们理解早期华裔新西兰人所面对的法律制度上的歧视吗?难道“恐华症”与“亲华症”仅仅是早期新西兰社会…     

Do the Effects of Head Start Vary by Parental Preacademic Stimulation?

Data from the Head Start Impact Study (N = 3,185, age = 3–4 years) were used to determine whether 1 year of Head Start differentially benefited children from homes with high, middle, and low levels of parental preacademic stimulation on three academic outcome domains—early math, early literacy, and receptive vocabulary. Results from residualized growth models showed positive impacts of random assignment to Head Start on all three outcomes, and positive associations between parental preacademic stimulation and academic performance. Two moderated effects were also found. Head start boosted early math skills the most for children receiving low parental preacademic stimulation. Effects of Head Start on early literacy skills were largest for children receiving moderate levels of parental preacademic stimulation. Implications for Head Start are discussed.
