保定军校毕业生与抗日战争

保定军校毕业生作为独立的军事体系,在抗日正面战场国民革命军将官中占很大比重,尤其在高级军官中始终占居第一位。他们参与指挥了正面战场几乎所有的重大战役,为捍卫国家主权和维护民族独立做出了不朽贡献。在战场上和抗战中,绝大多数保定军校毕业生以身许国,率部与敌搏杀,表现出高尚的爱国主义情操。     

Graphical Comparison of Covariance Matrices

Procedures for comparing within-group covariance matrices are developed, based on separate analyses of the variances and of the correlations. The variances and the correlations are represented as two two-way tables, with the columns representing groups. Graphical procedures based on comparisons of linear regressions are presented, by considering a multiplicative columns-regression model for the interaction of groups x variances and of groups x correlations. A multivariate comparison leads to the use of a generalized eigenanalysis to display any differences in covariance structure.     

On complete classes of experiments for certain invariant problems of linear inference

For certain non-singularly estimable full-rank appropriately invariant problems of linear inference in the setting of block designs, some complete classes of experiments have been characterized through the relation between the relevant C-matrices and their g-inverses (of the Moore-Penrose type) in regard to the specific invariance criterion discussed here. It follows that for a $\text{G}$-invariant non-singularly estimable full-rank problem, a complete class of experiments formally consists only of $\text{G}$-invariant designs.     

A Test of the False Positive Bias Hypothesis

An evaluation of the hypothesis that adolescent gamblers are biased toward the production of false positive responses proposed by Derevensky et al. was tested. The results of secondary analysis of available data supported the hypothesis for items on the South Oaks Gambling Screen and items from the DSM-IV screening instrument. The conclusions were presented as tentative in view of the modest sizes of the observed effects. A number of limitations to the analysis are also described.

A structured methodology to implement judiciously the right JIT tactics

In order to enhance the competitiveness and efficiency of manufacturing operations, many companies arc looking at implementing key strategic technologies. Two of the most predominant programs are ‘just-in-time’ and ‘synchronous organizations’. However, their impacts on improving quality and reducing time-to-market have been mixed. It is not very clear why, in some cases, results are poor, when in a similar situation, programmes have proved to work well. There are conflicting reasons reported for such a discrepancy. Some have argued that during J IT implementation either a right mix of tactics was not selected at the outset or the process was not carefully monitored to see whether a mid-course correction or change in tactics was necessary. In order to (a) protect the manufacturing and strategic teams from making the same/similar mistakes and (b) sustain a series of successful activity throughout during the strategic implementation cycle, this paper outlines a structured methodology. The method utilizes a matrix-based procedure to dynamically (over time) measure the effectiveness of a line of JIT tactics against the organization's principles and objectives. The operating procedure suggests first (a) using a method for monitoring the changing conditions of market and business and then (b) using the metrics to guide the management with a new line of tactics that might have better impact on the newly aligned company goals. In an effort to help managers and engineers decide on a proper line of tactics to implement JIT, a line of JIT quality matrices (JQM) is developed. JQM provides a framework to guide group managers to ‘plan, pick and choose’ a set of effective JIT techniques. An approach similar to quality function deployment (QFD) is used to generate the JIT house and their corresponding JQM matrices. With the JQM-based structured methodology, managers can design the best line of JIT strategy blended with JIT theory and adapted to the manufacturing environments in which it is expected to operate.     

Organizational Behavior Management and Industrial/Organizational Psychology

Abstract

Six scholars in applied psychology wrote thoughtful and provocative reactions to a paper written by the author that presented a case for broadening the content and language of organizational behavior management (OBM) in order to enhance appreciation for OBM in organizational settings and among university faculty and students in mainstream psychology programs. This paper summarizes the follow-up commentaries and adds justification for key points made in the target article. Five topics are addressed: (1) critical distinctions between OBM and industrial/organizational psychology, (2) disadvantages of using negative over positive reinforcement to motivate behavior change, (3) the need to after OBM language in order to increase interest and application, (4) the use of unobservable person state vs. personality traits to explain behavior, and (5) the challenge of improving the education and training of students in OBM programs.     

Enjoyment and absorption: An electronic diary study on daily flow patterns

Abstract

Flow experience is a state of mind in which one is totally absorbed in a task. This study explored the daily flow patterns related to working and non-working tasks among healthy and non-healthy (burned-out) individuals using the Experience Sampling Method. Previously the flow experience has been measured in terms of high challenges and high skills. The main aim of this study was to explore flow throughout the day using an operationalization that focused on the flow experience itself, as indicated by enjoyment and absorption. Forty healthy participants and 60 burned-out individuals kept an electronic diary on activities (work/non-work), and levels of flow (enjoyment and absorption) for 14 days. Entries were prompted by a signal on average five times a day, thus rendering 5455 entries. A curvilinear daily flow pattern was observed, with lower levels of flow during working hours. Differences were found between the components of flow: enjoyment was higher during non-working tasks, whereas absorption was higher when working. There were no differences in flow patterns between the healthy and burned-out group although the actual levels differed, with the former experiencing more flow than the latter. The results confirm the validity of this means of measuring flow, using enjoyment and absorption as indicators.     

信息不对称、噪声交易与IPO首日收益

IPO首日收益异象的形成一直有争议,而发行价偏低的抑价观点也受到某些实证研究的挑战。本文在一级市场中引入噪声申购者影响,并综合信息不对称和噪声交易两类因素,对IPO首日收益的形成进行研究并实证。研究发现,IPO首日收益与新股的一、二级市场错误定价均有关,前者由信息不对称和噪声申购者共同决定,后者由上市首日的噪声交易者(狂热投资者和正向反馈交易者)决定,其中后者的影响更强。
