苛敛型导师对科研创造力的影响：情感事件理论视角

根据情感事件理论,探究苛敛型导师影响研究生科研创造力的情感作用机制及边界条件。采用层级回归和Bootstrap法,对来自北京、上海、广东三地的342份全日制研究生数据进行分析,结果表明：①苛敛型导师与科研创造力显著负相关;②消极情感在苛敛型导师与科研创造力之间起部分中介作用;③敌意归因偏差不仅显著调节苛敛型导师与消极情感的关系,而且显著调节消极情感在苛敛型导师与科研创造力之间的中介作用,即敌意归因偏差越高,苛敛型导师对消极情感的促进作用越大,进而显著抑制科研创造力。     

The Test of Financial Literacy: Development and measurement characteristics

The Test of Financial Literacy (TFL) was created to measure the financial knowledge of high school students. Its content is based on the standards and benchmarks stated in the National Standards for Financial Literacy (Council for Economic Education 2013 Council for Economic Education (CEE). 2013. National standards in financial literacy. New York: CEE. [Google Scholar]). The test development process involved extensive item writing and review. Test data collected from 1,218 high schools to evaluate the measure indicate that the overall test is reliable and valid, and test items contribute to the effectiveness of the instrument. Further test analysis was conducted using an item response theory (IRT) model with four parameters to estimate item discrimination, item difficulty, guessing, and inattention. The IRT results indicate that the measure is effective in assessing student financial literacy across a broad range of student abilities.     

Bayesian analysis of Hong Kong's housing price dynamics

This paper uses a Bayesian vector‐autoregressive model with sign restrictions to estimate the underlying drivers of Hong Kong's housing price dynamics in the short run. While existing studies are useful in analysing housing valuation, little attention has been paid to the short‐run dynamics. In contrast, the present paper identifies short‐run drivers of housing prices using structural identification with theoretical underpinnings. We find that among the shocks that we have identified, bank lending shock and housing supply shock were the main factors affecting Hong Kong's housing prices. Low mortgage rates were another key factor that led to the significant increase in housing prices after the global financial crisis.     

Enhancing Insurer Value Using Reinsurance and Value-at-Risk Criterion

The quest for optimal reinsurance design has remained an interesting problem among insurers, reinsurers, and academicians. An appropriate use of reinsurance could reduce the underwriting risk of an insurer and thereby enhance its value. This paper complements the existing research on optimal reinsurance by proposing another model for the determination of the optimal reinsurance design. The problem is formulated as a constrained optimization problem with the objective of minimizing the value-at-risk of the net risk of the insurer while subjecting to a profitability constraint. The proposed optimal reinsurance model, therefore, has the advantage of exploiting the classical tradeoff between risk and reward. Under the additional assumptions that the reinsurance premium is determined by the expectation premium principle and the ceded loss function is confined to a class of increasing and convex functions, explicit solutions are derived. Depending on the risk measure's level of confidence, the safety loading for the reinsurance premium, and the expected profit guaranteed for the insurer, we establish conditions for the existence of reinsurance. When it is optimal to cede the insurer's risk, the optimal reinsurance design could be in the form of pure stop-loss reinsurance, quota-share reinsurance, or a combination of stop-loss and quota-share reinsurance.

Initial assessment and validation of an instrument to measure student perceptions of leadership skills

This article reports on development and validation of an instrument for use in measuring student perceptions of leadership skills. The article describes the development process of an instrument through use of subject matter experts for measuring leadership skill perception among students and use of an exploratory factor analysis technique to validate the resulting instrument. These data were obtained from a survey of 214 students in a small liberal arts college of business. The article presents an instrument for assistance with measuring leadership skill perception, development, and importance as well as further reports on the initial validity and reliability measures resulting from the analysis. In addition, the usefulness of the instrument for educators and workplace trainers is explored.     

A Rotated Dynamic Nelson‐Siegel Model

I show how to rotate the factor structure of the well‐known Dynamic Nelson‐Siegel yield‐curve model to enable direct parametrization of the short rate process. This makes it easy to calculate model‐implied term premia and to integrate macroeconomic variables into the model in a Taylor‐rule‐type fashion.     

It's time to retire. Retirement

Companies have been so focused on down-sizing to contain costs that they've largely neglected a looming threat to their competitiveness: a severe shortage of talented workers. The general population is aging and with it, the labor pool. People are living longer, healthier lives, and the birthrate is at a historical low. During the next 15 years, 80% of the native-born workforce growth in North America--and even more in much of Western Europe--is going to be in the over-50 age cohort. When these mature workers begin to retire, there won't be nearly enough young people entering the workforce to compensate. The Bureau of Labor Statistics projects a shortfall of 10 million workers in the United States in 2010, and in countries where the birthrate is well below the population replacement level (particularly in Western Europe), the shortage will hit sooner, be more severe, and remain chronic. The problem won't just be a lack of bodies. Skills, knowledge, experience, and relationships walk out the door every time somebody retires--and they take time and money to replace. And while the brain drain is beginning now, the problem is going to become much more acute in the next decade or so, when baby boomers--more than one-quarter of all Americans, amounting to 76 million people--start hitting their mid sixties. Based on the results of their yearlong research project, the authors of this article offer recommendations for gaining the loyalty of older workers and creating a more flexible approach to retirement that allows people to continue contributing well into their sixties and seventies. Companies can no longer afford to think of retirement as a onetime event, permanently dividing work life from leisure.     

The impact of workplace support and identity on training transfer: a case study of drug and alcohol safety training in Australia

Previous research has indicated that the transfer climate of work organisations is an important factor in determining the degree to which knowledge, skills and abilities gained in training transfer to the workplace. In particular, workplace social support from supervisors and coworkers is consistently cited as an important factor that can facilitate or inhibit training transfer. However, research evidence regarding the impact of workplace social support on training transfer is mixed. In order to address this issue a study was conducted to identify under what conditions workplace social support impacts on training transfer. This study evaluated a workplace drug and alcohol training programme * * The training evaluated in this study is part of the Building Trades Group Drug and Alcohol Programme. This is a national drug and alcohol programme for the Australian Building and Construction Industry. For more information on this programme, visit: http//www.btgda.org.au .
to examine the impact of workplace social support and identification with workplace groups on training transfer. Results indicated that the influence of workplace social support on training transfer was moderated by the degree to which trainees identified with workplace groups that provided this support. This study supports the proposition that in order to fully understand training transfer, and to design effective training programmes, training research and practice needs to focus on both the personal and situational factors that may interact to influence learning and transfer.
