The purpose of the present article is to investigate the impact of psychological ownership, job performance, job commitment, and job satisfaction among business school lecturers of public universities in Malaysia. As psychological ownership is a relatively new concept, the present study expands the use of it in a different setting. Based on the correlation analysis, it was found that psychological ownership had significant and positive relations with job commitment, job satisfaction, and performance. The findings of the present study can help the management of universities select the lecturers with a right attitude and provide them with a right environment to perform better.  相似文献

By applying multilevel models with random effects, the authors reviewed and synthesized findings from 30 studies that were published in the last 20 years exploring the relationship between the Educational Testing Service Major Field Test for a Bachelor's Degree in Business (MFTB) and related factors. The results suggest that MFTB scores correlated moderately with overall grade point average (.45) and ACT or SAT scores (.56) across the studies, before accounting for imperfect reliability or range restriction issues, which supports the claim that the MFTB is a valid assessment tool to gauge information about business-related learning outcomes for a variety of colleges and universities that are similar to those included in the studies.  相似文献

In a recent issue of this journal [2] McCain and Millar examined whether “favorable” and unfavorable” stock analyses appearing in the Wall Street Journal column “Heard on the Street” could be used to predict one-day, seven-day, and six-month price movements of the affected stocks. In this note we question the conclusions of that study based upon methodological grounds.  相似文献

Abstract

Business performance measurement and management (PMM) systems are often viewed as relatively recent phenomena, responding to the failure of historical practices which prioritised financial measures. But despite the considerable focus on these systems over the last 25 years, they have not lived up to their early promise. This article looks backwards to understand how practitioners managed their performance in the past. It focuses on two British multiple retailers between 1920 and 1939 and highlights not only the formal processes they adopted but also the role of the informal processes which shaped how they achieved their objectives.  相似文献

Regulation imposes compliance demands on business, but these controls by no means ensure that corporations will act ethically. Externally imposed controls by government or industry are prompts intended to move organizations to engage in a moral minimum. Such efforts are typically reactionary corrective measures, often crafted and applied after an ethical scandal occurs, and thereby offer limited effectiveness in providing systemic change. To provide insight on internally driven controls, this article examines how a newer form of monetized self-regulation, referred to as inverted moral markets, might be leveraged to motivate corporate ethical behavior. Inverted moral market (IMM) operations target firms suspected of unethical action, providing a type of market whistleblowing. Such activities are monetized through the sale of information to investors and by short selling. Rather than a desire to build moral strength, IMM firms are motivated by self-interest and profit. They can potentially ‘do good’ by imposing self-correction within the market, but without virtuous intent. We explore IMMs and the varied impacts their activities may have on the functioning of the overall market. We argue that a more balanced approach between internal and external regulation may enhance the environment for moral balance in a capitalist market system.  相似文献

In this paper, we introduce a functional method to investigate how betas change over time in factor models. Based on the China A-share data, we drop the constant beta assumption in the CAPM and multi-factor models to estimate the time-varying betas directly from the functional data regression. The empirical results show that exposures to all risk factors have certain time-varying patterns in the Chinese A-share stock market.  相似文献

Sparse generalised additive models (GAMs) are an extension of sparse generalised linear models that allow a model's prediction to vary non-linearly with an input variable. This enables the data analyst build more accurate models, especially when the linearity assumption is known to be a poor approximation of reality. Motivated by reluctant interaction modelling, we propose a multi-stage algorithm, called reluctant generalised additive modelling (RGAM), that can fit sparse GAMs at scale. It is guided by the principle that, if all else is equal, one should prefer a linear feature over a non-linear feature. Unlike existing methods for sparse GAMs, RGAM can be extended easily to binary, count and survival data. We demonstrate the method's effectiveness on real and simulated examples.  相似文献
