In the past, researchers have explored virtual reality (VR) as an educational tool primarily for training or therapeutic purposes. In this research, the authors examine the potential for using Google Cardboard VR in business classrooms as a content delivery platform. They specifically investigate how VR (viewing a 3-dimensional, 360° video) differs from the traditional flat-screen (FS) format (viewing a 2-dimensional video [e.g., iPod (Apple, Cupertino, CA)]) as a teaching tool to deliver video-based content. The results demonstrate that participants in the VR condition (vs. the FS condition) rated their enjoyment and interest to be higher. However, the Google Cardboard VR platform was not superior to the iPod FS format in its content delivery with respect to novelty, reliability, and understandability. 相似文献

In this research, continuous and dynamic Berth Allocation Problem (BAP) is studied to minimize the total weighted flow time. Different from previous studies on continuous BAP, an efficient method is proposed to address the problem to identify the possible locations for next vessel in the Time-space diagram. Then two versions of Greedy Randomized Adaptive Search Procedure (GRASP) are developed to search for near optimal solutions. Both small and large scale numerical experiments are tested to examine the effectiveness of the proposed GRASPs by comparison with CPLEX and stochastic beam search, respectively. 相似文献

While many studies of the motivations behind the corporate social responsibility reporting (CSRR) practices of large corporations have been reported internationally, few have focussed on multinational corporation (MNC) subsidiaries. Most importantly, we still do not know how host country institutional norms, or parent corporation policies, influence MNC subsidiaries embarking upon CSRR. By integrating legitimacy theory (LT) and neo-institutional theory (NIT) explanations, this paper offers a theoretical framework for investigating the CSRR practices of MNC subsidiaries in general, and provides empirical evidence on the nature and motivations of subsidiaries’ CSRR practices in Bangladesh, a developing country. Employing a case study method and using qualitative data, the study finds that CSRR practice in Bangladeshi MNC subsidiaries is limited, consisting mainly of employee information. This observation mirrors the overall CSRR trend in Bangladesh. A desire for internal legitimacy emerges as the primary motivation for CSRR practice in MNC subsidiaries. In particular, the external host country environment of the Bangladeshi subsidiaries seems to be a major limitation in the development of CSRR. 相似文献

We examine how organizational structure influences strategies over which corporate leaders have significant discretion. Corporate philanthropy is a strategic activity commonly managed through a specific, differentiated organizational structure—the corporate foundation—that formalizes and constrains the influence of individual senior managers and directors on corporate strategy. Our analysis of Fortune 500 firms from 1996 to 2006 shows that characteristics of senior management and directors affect corporate philanthropic contributions. We also find that organizational structure constrains the philanthropic influence of board members, but not of senior managers, a result contrary to what existing theory would predict. We discuss how these findings advance understanding of how organizational structure and corporate leadership interact and how organizations can more effectively realize the strategic value of corporate social responsibility activities. 相似文献

This paper examines the effect of unanticipated money on output, unemployment and prices in Korea. The empirical results tend to reject the policy ineffectiveness proposition (PIP) in most cases. They show that both anticipated and unantipated money affect output and prices, in contract with the PIP. Mixed results are obtained for the effect of monetary variables on unemployment. The statistical results show that the regular OLS two step estimates yield t values which are upward biases by 0–27% as compared with the consistent estimates of the variance-covariance matrix that are obtained in this study.

This paper examines the real and financial integration of East Asian economies, by comparing the degree of real vs financial and global vs regional integration, before vs after the Asian crisis. First, price and quantity measures such as the size of intra‐ and inter‐regional trade, cross‐border financial assets, stock return correlation, and interest rate differentials are investigated. Second, the structural panel vector autoregression (VAR) model is constructed to analyze macroeconomic consequences of real and financial integration such as cross‐country output and consumption relation. The results suggest that (i) the degree of real integration significantly increased after the crisis, both regionally and globally; (iii) quantity and price measures showed an increased financial integration after the crisis, but the consumption relation did not; (iv) the degree of regional financial integration is smaller than that of global financial integration, based on the consumption relation; and (v) financial integration lags real integration, especially for regional integration. 相似文献

The main approach to deal with regressor endogeneity is instrumental variable estimator (IVE), where an instrumental variable (IV) m is required to be uncorrelated to the regression model error term u (COR(m,u)=0) and correlated to the endogenous regressor. If COR(m,u)≠0 is likely, then m gets discarded. But even when COR(m,u)≠0, often one has a good idea on the sign of COR(m,u). This article shows how to make use of the sign information on COR(m,u) to obtain an one‐sided bound on the endogenous regressor coefficient, calling m a ‘generalized instrument’ or ‘generalized instrumental variable (GIV)’. If there are two GIV's m1 and m2, then a two‐sided bound or an improved one‐sided bound can be obtained. Our approach is simple, needing only IVE; no non‐parametrics, nor any ‘tuning constants’. Specifically, the usual IVE is carried out, and the only necessary modification is that the estimate for the endogenous regressor coefficient is interpreted as a lower/upper bound depending on the prior notion on the sign of COR(m,u) and some estimable moment. A real data application is done to Korean household data with two or more children to illustrate our approach for the issue of child quantity–quality trade‐off. 相似文献

This study was designed to identify determinants of employee willingness to use feedback for performance improvement. The proposed determinants included objectives of appraisal, supervisor's knowledge of subordinate's job, agreed plan for performance improvement, trust in supervisor and perceived fairness and accuracy of performance evaluation. Data were collected in two phases. The first phase consisted of a questionnaire survey among 100 Hong Kong Chinese employees working in public and private sector organizations. Regression analysis of questionnaire data indicated that agreed plan for performance improvement and perceived fairness and accuracy of performance evaluation had significant positive effects on employee willingness to use performance feedback. In the second phase, focus group interviews were held to triangulate survey findings. Interview data suggested that Chinese cultural characteristics of paternalism and personalism influenced the underlying dynamics of the evaluation process. Findings are interpreted in the context of employees cultural and organizational background. 相似文献
