This study examined the emergence and subsequent five-year history of environmental scanning at a large research university. Proponents of strategic approaches to management in organizations usually recommend environmental scanning as a necessary support for effective decision making. The technique seeks to build systematic understanding of the external environment of the organization, via ongoing reconnaissance of relevant developments in technology, the economy, the political and legal arenas, and the larger society. Scanning's fit with educational organizations may be problematic, however. Over time, scanning efforts on the campus studied here became less theory-based and less centralized, and scanning failed to become an institutionalized innovation. The difficulties in institutionalizing scanning are traced to six factors: limitations posed by organizational structure, an absence of powerful champions, constraints from the organizational culture, the existence of a policy vacuum surrounding scanning efforts, the daunting demands of such efforts themselves, and questionable articulation with the fundamental goals and mission of the institution. The analysis suggests that the generic scanning model seems unlikely to win acceptance in research universities without substantial modification.His research and his teaching focus upon organization and policy in higher education. Among his current research projects are an investigation of the changing demography of the professoriate and a study of the effects of the ongoing centralization of higher-education governance at the state level in the U.S. His Ph.D. is from Stanford University.His primary focus is assisting academic disciplines and institutions in developing ecologically sensitive curricula and sustainable practices.He received his Ph.D. from the University of Michigan. 相似文献

Flexible coursework delivery to Australian postgraduates: How effective is the teaching and learning? 总被引:2,自引:0,他引:2
The educational implications of non-traditional delivery methods atpostgraduate level are not yet well understood. A major question is whetheradvantages of access and flexibility are accompanied by trade-offs inlearning experiences and outcomes. In this paper we address the effectivenessof delivery methods currently used in postgraduate coursework programs inAustralia. We draw heavily on a national study of flexible delivery methodsin postgraduate education, conducted in 1995.Following a nation-wide survey, we investigated the effects of deliverytechnologies on learning and teaching in seven postgraduate courses.Information was collected, mostly by taped interview, from staff andstudents, and also from course documentation. We present here a typology,based on teaching and learning characteristics, by which we found it usefulto group delivery methods. We identify and discuss four major issuesconcerning the effects of these delivery methods on learning and on teaching,under the headi ngs learner control of learning, interaction and socialexchange, teachers as supporters of student learning and feedback inteaching. As well, we report, according to the typology, the effects ofspecific technologies on teaching and learning.We conclude that on the score of encouraging intellectual independencemany non-traditional delivery methods are fairly robust – on managingcomplexity or uncertainty and encouraging a lively critical inquiry, theyfare less well. From what we have seen, the most effective strategies atpostgraduate level use integrated delivery approaches to create flexiblelearning environments with premiums on individual time management andpractical application of learning. Considerably more detailed evaluation ofthe resulting learning outcomes is needed. 相似文献

Summary The evaluation and selection of interactive video hardware is a difficult process even for experts. There seems to be a multitude
of models, options, peripherals, and prices. The task becomes even more perplexing because of rapid advances in the technology.
What is new today may be obsolete tomorrow. Using the checklist should help make your job easier. It allows you to compare
computers “apple for apple.” The recommendations listed are general suggestions. Different organizations may require most
or less than what is recommended. Always plan for at least the minimum requirements of your software, even if those requirements
are above our recommendations. 相似文献

Bereavement is a state of grieving after the loss of a loved one. Past research has suggested that bereavement is particularly challenging, both physically and emotionally, in the aftermath of unexpected death. Here, we examine bereavement in which death occurred suddenly, compared to a chronic condition where death was expected, in terms of perceived social support and relational maintenance with the deceased in the form of imagined interactions and social media interactions. Results indicated that individuals experiencing sudden death bereavement were more likely to engage in both postmortem relational maintenance techniques and perceived less social support than individuals in the expected death bereavement group. Results are discussed in terms of previous findings. 相似文献

This article draws on the concepts of narrative interactivity and closure to investigate three World War II-era print media characters. The analysis details how Al Parker’s Mary & Jane and Norman Rockwell’s Willie Gillis developed a perceived authenticity that invited fans to envision the propaganda drawings as having lives beyond their artistic origins. The essay concludes that the narrative arcs of these characters prefigured the imagined relationships that subsequent generations developed with televised characters. 相似文献
