Information technology (IT) outsourcing vendor organizations contain isolated business units whose creation and sustenance greatly facilitate business operations. But they also introduce important challenges for organizational knowledge management (KM). In this paper, based on 7 months of intensive field-work at India Inc., a leading Indian IT firm, we looked at how members’ identification with two organizations, their own and their client organization, influences their compliance with an organizational KM initiative. The findings show that members have difficulties in complying with the expectations of the organizational KM initiative owing to a stronger identification with their client organizations. At the same time, they comply readily with KM initiatives at the business unit level. The findings show that KM managers at India Inc. use the help of middle level managers in the business units in their efforts to improve members’ compliance with organizational KM. Theoretical and managerial implications of the study are discussed. 相似文献

HIV/AIDS harms the viability and competitiveness of African businesses. As a consequence, companies increasingly subscribe to the view that taking a proactive role to combat HIV/AIDS is not simply a question of compassion and good corporate citizenship. Rather, these firms see assertive action against HIV as critical to their long‐term profitability, and some have concluded that it is cost effective even in the short term. The article discusses how South African companies are taking action against HIV in ways that set new benchmarks, enhance the effectiveness of international AIDS advocacy efforts, and spur businesses across Africa and beyond to strengthen their corporate responses to HIV/AIDS. 相似文献

This article investigates the role of commonly specified control variables in moderating the relationship between corporate social performance (CSP) and corporate financial performance (CFP). In addition, there are separate measures for positive (strengths) social actions, and for negative (concerns) social actions. The results support the positive relationship between CSP and CFP. The best model, as determined using factorial analysis of variance, is one which has the following control variables: size, industry, risk, and research and development expenditures. In examining the CSP/CFP relationship, researchers must control for these variables, in order to properly specify the model. 相似文献

Carriers (airlines) use medium‐term contracts to allot bulk cargo capacity to forwarders who deliver consolidated loads for each flight in the contractual period (season). Carriers also sell capacity to direct‐ship customers on each flight. We study capacity contracts between a carrier and a forwarder when certain parameters such as the forwarder's demand, operating cost to the carrier, margin, and reservation profit are its private information. We propose contracts in which the forwarder pays a lump sum in exchange for a guaranteed capacity allotment and receives a refund for each unit of unused capacity according to a pre‐announced refund rate. We obtain an upper bound on the informational rent paid by the carrier for a menu of arbitrary allotments and identify conditions under which it can eliminate the informational rent and induce the forwarder to choose the overall optimal capacity allotment (i.e., one that maximizes the combined profits of the carrier and the forwarder). 相似文献

For firms remanufacturing their products, the total life‐cycle costs and revenues from new and remanufactured products determine their profitability. In many firms, manufacturing/sales and remanufacturing/remarketing operations are carried out in different divisions. Each division is responsible for only part of the product's life cycle. Practices regarding transfer pricing across divisions vary significantly among companies, affecting the life‐cycle profit performance of the product. In this research, we identify characteristics of transfer prices that achieve the firm‐wide optimal solution. To this end, we consider a manufacturer who also undertakes remanufacturing operations and we focus on price (quantity) decisions. We determine that a cost allocation mechanism that allocates a portion of the initial production cost to each of the two stages of the product life cycle should be used. We also conclude that cost allocation should be implemented as a fixed cost allocation, where charges to the remanufacturing division should be determined independently of the actual quantity of units remanufactured. 相似文献

Let G=(V,E) be a graph without an isolated vertex. A set D⊆V(G) is a k
-distance paired dominating set of G if D is a k-distance dominating set of G and the induced subgraph 〈D〉 has a perfect matching. The minimum cardinality of a k-distance paired dominating set for graph G is the k
-distance paired domination number, denoted by γ

(G). In this paper, we determine the exact k-distance paired domination number of generalized Petersen graphs P(n,1) and P(n,2) for all k≥1. 相似文献

This paper numerically examines the size robustness of various conditional moment tests in misspecified tobit and probit models. The misspecifications considered include the incorrect exclusion of regressors, ignored heteroskedasticity and false distributional assumptions. An important feature of the experimental design is that it is based on an existing empirical study and is more realistic than many simulation studies. The tests are seen to have mixed performance depending on both the original null hypothesis being tested and type of misspecification encountered. 相似文献

Middle managers in today's organisations have reported experiencing longer working hours and intensified work regimes. These increased pressures, in turn, have led to growing difficulty in addressing the integration of their work and personal lives. In an exploratory study of the daily workplace experiences of Australian middle managers and the impacts on their personal lives, one of the key themes to emerge was respondents’ concerns about the negative effects on their friendships. This paper discusses middle managers’ recognition of the value of friendships for their wellbeing, and the resultant anger and sadness reported at the strain on these relationships due to competing time demands. The significant role that friendships play in alleviating some of the stresses of work demands, while concurrently being impeded by these same demands, is an important issue for organisations to consider. These findings indicate the need for middle managers to truly have an ability to engage in activities – and friendships – which will aid them in their working lives. The study also indicates a need for further investigation into the development and maintenance of friendships for both middle managers and other groups of employees. 相似文献

Abstract. The large deviation modified likelihood ratio statistic is studied for testing a variance component equal to a specified value. Formulas are presented in the general balanced case, whereas in the unbalanced case only the one-way random effects model is studied. Simulation studies are presented, showing that the normal approximation to the large deviation modified likelihood ratio statistic gives confidence intervals for variance components with coverage probabilities very close to the nominal confidence coefficient. 相似文献
