Management personnel are increasingly aware that career success depends on the ability to continuously learn and adapt to the environment. However, scant attention has been paid to how learning activities contribute to managerial success. This study examines the degree to which involvement in career‐related continuous learning affects managerial career success. Career success as defined in this study comprises both objective (ascendancy) and subjective (organizational commitment, professional commitment, career satisfaction) elements. Five hypotheses are tested using linear regression modeling. Results indicate that as individuals increase participation in career‐related continuous learning, their managerial career success increases as well. 相似文献
A new, simple classroom technique helps cell biology students understand principles of Michaelis-Menten enzyme kinetics. A student mimics the enzyme and the student's hand represents the enzyme's active site. The catalytic event is the transfer of marbles (substrate molecules) by hand from one plastic container to another. As predicted, increases in marble concentration increase the number of marbles transferred per unit time (initial rate, V(0)) until the turnover number becomes rate limiting and V(0) approaches the maximum velocity (V(max)), as described by the Michaelis-Menten equation. With this demonstration, students visualize an important concept: the turnover number is constant and independent of marble concentration. A student assessment of this exercise showed that it helped students visualize the turnover number and V(max) but not K(m), the marble concentration at which V(0) is one-half V(max). To address the concept of K(m), we use supplemental laboratory and lecture exercises. This exercise with plastic containers and marbles is equally suited to demonstrate the kinetics of carrier-mediated membrane transport. We conclude that this exercise helps students visualize the turnover number and V(max) and gives students important insights into the kinetic parameters used to characterize the catalytic activity of enzymes and membrane transporters. 相似文献
Working memory refers to a mental workspace, involved in controlling, regulating, and actively maintaining relevant information to accomplish complex cognitive tasks (e.g. mathematical processing). Despite the potential relevance of a relation between working memory and math for understanding developmental and individual differences in mathematical skills, the nature of this relationship is not well-understood. This paper reviews four approaches that address the relation of working memory and math: 1) dual task studies establishing the role of working memory during on-line math performance; 2) individual difference studies examining working memory in children with math difficulties; 3) studies of working memory as a predictor of mathematical outcomes; and 4) longitudinal studies of working memory and math. The goal of this review is to evaluate current information on the nature of the relationship between working memory and math provided by these four approaches, and to present some of the outstanding questions for future research. 相似文献
The National Survey of Student Engagement has been administered to freshmen and seniors at colleges and universities across the USA and Canada, since the spring of 2000, to gather information about the nature and the quality of their education. After each administration, participating schools are provided with an institutional report, including results for five benchmarks of effective educational practice. The purpose of this study was to examine the utility of these benchmark scores at a particular university. The results of a confirmatory factor analysis suggest that the benchmarks are not valid indicators of students’ perceptions at this school. Discussion regarding uses of national data collections for individual institutions is provided.
Background: Most NHS library services routinely offer both mediated searches and information skills training sessions to their users. We analyse the impact of these two services on the amount of literature searching demonstrated by users of hospital‐ based library services in the north‐west of England. Methods: Data for (1) mediated literature searches, (2) number of library users attending information skills training sessions, (3) amount of library staff time devoted to information skills training, and (4) number of Athens‐authenticated log‐ins to databases were obtained from statistical returns for 2007, and analysed for significant correlations. Results: There was evidence of quite strong correlations between the two measures of training activity and the number of mediated literature searches performed by library staff. There was weaker evidence of correlation between training activity and total literature searching activity. Discussion: Attending training sessions may make some library users aware of the difficulty of complex literature searches and actually reduce their confidence to perform their own complex searches independently. The relationships between information skills training, mediated literature searches, and independent literature searching activity remain complex. 相似文献
Test administrators are appropriately concerned about the potential for time constraints to impact the validity of score interpretations; psychometric efforts to evaluate the impact of speededness date back more than half a century. The widespread move to computerized test delivery has led to the development of new approaches to evaluating how examinees use testing time and to new metrics designed to provide evidence about the extent to which time limits impact performance. Much of the existing research is based on these types of observational metrics; relatively few studies use randomized experiments to evaluate the impact time limits on scores. Of those studies that do report on randomized experiments, none directly compare the experimental results to evidence from observational metrics to evaluate the extent to which these metrics are able to sensitively identify conditions in which time constraints actually impact scores. The present study provides such evidence based on data from a medical licensing examination. The results indicate that these observational metrics are useful but provide an imprecise evaluation of the impact of time constraints on test performance. 相似文献
This forum seeks to problematise issues related to the lack of resources to adequately finance public education systems. It explores potential solutions based on increased domestic resource mobilisation through progressive taxation in order to meet the growing financing gap needed to achieve Sustainable Development Goal (SDG) 4. While many governments in poor countries are already demonstrating a strong commitment to funding education, the papers will argue that they could raise more money by broadening their tax base – for example, by reducing the prevalence of harmful tax incentives or tackling tax avoidance. Steven Klees’s contribution examines the proposals made by the International Commission on Financing Global Education Opportunity as well as the potential for global taxation mechanisms to be used to finance the education and other SDGs. David Archer argues that SDG4 requires a rebuilding of confidence in the capacity of governments to finance good-quality public education through progressive taxation. Finally, Maria Ron Balsera’s contribution uses Pakistan, Ghana, Kenya and Uganda as case studies to analyse the effect of the inadequate financing of education and to explore sustainable and equitable solutions. 相似文献
This paper reviews the nature and implementation of the Australian VET FEE-HELP (VFH) policy initiative: a scheme introduced in 2008 to extend income-contingent loans to the vocational education and training (VET) sector in Australia. We argue that the implementation of the scheme has been seriously flawed, leading to a range of counter-educational and unethical practices on the part of some VET providers. An ongoing research project into the impact of the changing contemporary cultural context of VET on the creation of moral dilemmas facing VET teachers in their work has identified four dilemmas that were seen by teachers to be significantly driven by the VFH scheme. Those dilemmas arose from (1) unethical student recruitment and enrolment practices, (2) overlooking traditional educational standards, (3) constraining teacher responsiveness and (4) manipulating learning assessment. The identifying teachers saw themselves as being professionally unprepared to handle such moral dilemmas, leading to discomfort and inappropriate handling of the dilemmas. 相似文献
