Generational and life course theory lenses were placed upon one finding of a large-scale qualitative interview-based study focused on if and how community college faculty members construct work–life balance. Twenty-eight interviews with faculty members at a midwestern community college were conducted. Differences regarding to work-life balance approaches between Baby Boomer (n = 15) and Generation X (n = 13) faculty and as mediated by position within the life course are elucidated. We termed this finding tides of life, which is comprised of three subfindings: roles, tenure, and gender performance. Practical implications of this finding are put forward. Better understanding of the nuanced ways in which community college faculty construct work–life balance can inform policy decisions that impact faculty work. Moreover, better understanding of faculty life in a general sense is critical as community college leaders craft policies and refine practices related to faculty employment contracts, work environments, support mechanisms, professional development, and mentoring.  相似文献

Third-, sixth-, and ninth-grade teachers in a Wisconsin county nominated 982 children as consistently displaying socially approved behavior and 568 as consistently displaying aggressive-disruptive behavior in the classroom. Five years after the original nominations teacher grades in English, science, mathematics, and social studies; rank in graduating class for original ninth graders; and STEP scores were obtained. Analyses of covariance (ANACOVA) were made with IQ as the covariate and behavior, grade, sex, and home location as the independent variables. The results indicate clearly that the children whose behavior was aggressive and disruptive in the classroom achieved at significantly lower levels than their socially approved peers.  相似文献

Abstract

This article describes the reflective process used by a group of early childhood faculty members to study national standards in order to improve their teacher education program. The standards studied included those from the National Association for the Education of Young Children (NAEYC), Interstate New Teacher Assessment and Support Consortium (INTASC), National Board for Professional Teaching Standards (NBPTS) and the Division for Early Childhood of the Council for Exceptional Children (DEC/ECE). The reflective process and study resulted in changes in field experiences, course requirements and activities and assisted in state and national accreditation.  相似文献

The common practice of using discussion groups during case-based learning makes the role of discussion important in these learning environments. However, little empirical research has been done to investigate the influence of discussion on performance and motivation in case-based learning. The purpose of this article is to present the results of a study conducted to examine the role of discussion groups in a case-based environment. College students completed two cases either individually or in small discussion groups. Measures included two case analyses, an attitude survey, time on task, and document analysis. Results revealed significant performance and time differences between instructional methods on the first case, but not on the second case. In addition, results indicated significant differences in student attitudes between treatments. Overall, participants who worked in groups liked their method significantly better than those who worked alone, felt they learned more working in a group than they would have working alone, and expressed a preference for working in a group if they had to do the class over again. Implications for implementing case-based learning and future research are discussed. Anna E. Flynn is Vice President and NAPM Associate Professor with the National Association of Purchasing Management.  相似文献

The effectiveness of a nap as a recovery strategy for endurance exercise is unknown and therefore the present study investigated the effect of napping on endurance exercise performance. Eleven trained male runners completed this randomised crossover study. On two occasions, runners completed treadmill running for 30?min at 75% ?O2max in the morning, returning that evening to run for 20?min at 60% ?O2max, and then to exhaustion at 90% ?O2max. On one trial, runners had an afternoon nap approximately 90?min before the evening exercise (NAP) whilst on the other, runners did not (CON). All runners napped (20?±?10?min), but time to exhaustion (TTE) was not improved in all runners (NAP 596?±?148?s vs. CON 589?±?216?s, P?=?.83). Runners that improved TTE after the nap slept less at night than those that did not improve TTE (night-time sleep 6.4?±?0.7?h vs. 7.5?±?0.4?h, P?r2 ? =??0.76, P?=?.001). In runners that improved TTE, ratings of perceived exertion (RPE) were lower during the TTE on NAP than CON compared to runners that did not improve (?0.4?±?0.6 vs. 0?±?0, P?=?.05). Reduced exercising sense of effort (RPE) may account for the improved TTE after the nap. In conclusion, a short afternoon nap improves endurance performance in runners that obtain less than 7?h night-time sleep.  相似文献

The World Wide Web is a popular “tool” for companies. It can be used as a method of communication between companies and their customers; it also allows organizations to setup virtual storefronts that can be accessed by customers from all over the world. The ability to understand customers’ behavior is extremely important as companies strive to increase the usability and profitability of their web service. The concept of a session is a popular unit of measurement used to analyze recorded information. However, this concept is currently rather abstract and lacks definition. How we measure a session is a fundamental question for web services utilizing this concept. Currently, this question has no real answer. This paper presents a session timeout threshold model based on empirical observations as an initial answer to this question. The model seeks to provide accurate session data with respect to individual web services.  相似文献

This essay describes a new ethical theory that has begun to coalesce from the works of several scholars in the international computer ethics community. I call the new theory ‚Flourishing Ethics’ because of its Aristotelian roots, though it also includes ideas suggestive of Taoism and Buddhism. In spite of its roots in ancient ethical theories, Flourishing Ethics is informed and grounded by recent scientific insights into the nature of living things, human nature and the fundamental nature of the universe – ideas from today’s information theory, astrophysics and genetics. Flourishing Ethics can be divided conveniently into two parts. The first part, which I call ‚Human-Centered FE,’ is focused exclusively upon human beings – their actions, values and characters. The second part, which I call ‚General FE,’ applies to every physical entity in the universe, including humans. Rather than replacing traditional ‚great ethical theories,’ Flourishing Ethics is likely to deepen and broaden our understanding of them.  相似文献

This study determines the optimal vascular designs for perfusing engineered tissues. Here, "optimal" describes a geometry that minimizes vascular volume fraction (the fractional volume of a tissue that is occupied by vessels) while maintaining oxygen concentration above a set threshold throughout the tissue. Computational modeling showed that optimal geometries depended on parameters that affected vascular fluid transport and oxygen consumption. Approximate analytical expressions predicted optima that agreed well with the results of modeling. Our results suggest one basis for comparing the effectiveness of designs for microvascular tissue engineering.  相似文献

参考文献表的编排有多种体例形式,并且不同体例中参考文献各著录项的表达也不尽相同。由于期刊大都倾向于采用自己所特定的参考文献著录格式,因而目前已有的参考文献软件并不能给予作者很多帮助,即作者如果将其稿件由某期刊改投到另一种期刊,通常需要改动其中的参考文献表格式和正文中的相关部分。在众多的参考文献表格式中,有两种最为主要。其一是在人文科学中较为常用的哈佛体系(即著者一出版年体系),该体系规定正文中给出引文的作者和出版年,文献书目中的引文按著者姓名的字母顺序和出版年的先后排列。另外一种主要的参考文献表是数字体系(顺序编码制),即正文中给出引文的序号,参考文献表中的各篇文献按其在正文中出现的先后顺序排列。科技论文和医学论文多采用该种体例。本文列举了上述两种体例的格式,并对比了二者的优缺点,认为著者.出版年体系可以使学术论文的读者很方便地了解作者所引用的工作是由谁完成的,而数字体系(顺序编码制)因为简洁,从而可以使读者更为通畅地阅读论文。  相似文献
