Transition from a planned command economy to a market economy means tearing down a socio-economic setting where everybody follows orders and nobody bears individual responsibility for anything. The absence of personal responsibility does not promote ethical behavior in any walk of life. Today, the malnourished business ethics in the former Soviet Union creates a critical obstacle to economic development. The paucity of new official rules governing the conduct of business makes the transition process painful and difficult to people habituated to numberless rules and regulations. The first part of this paper surveys the most visible unethical business practices that have been reported by the Western media and those that are causing the largest number of complaints by the local governments and businessmen. The second part of the paper looks at ethical problems that have been under-reported.  相似文献

Mine accidents/injuries can be cross-classified against the variables of interest in a contingency table and their associations can be assessed through aggregate statistics. However, there is a need to develop a coherent and structured procedure for analysis of accident data, which will allow one to identify associations between two or more variables multivariately. In this study, the loglinear model, which has been proposed as a mathematical representation of the contingency table, was applied to accident data from a group of coal mines to assess the associations/interactions between two or more variables multivariately through their main and interaction effects. The case study results revealed that the variables ‘occupation’ and ‘workplace location’ were highly associated with degree of injury. It was also clearly indicated that the workers with more than 20 years of experience exhibited high injury rate patterns. While designing training programs for miners, focused attention should be given to specific categories of workers to reduce accident/injuries at the case study mines.  相似文献

Whilst strategic alliance performance has been extensively researched through the resource-based lens, it has yet to be examined under the natural-resource-based view (NRBV) of the firm. Building on the NRBV, this article argues that a firm’s level of environmental proactiveness affects its level of alliance satisfaction. The argument is tested by surveying Norwegian CEOs, and the results confirm a positive relationship. Moreover, the partner’s environmental proactiveness equally influences the focal firm’s satisfaction with the alliance, in consistent with related studies. In addition to providing new empirical evidence in support of the NRBV, and extending the alliance performance literature, the findings add to the corporate environmentalism literature by offering insights on the virtues of green strategies in an underexplored context.  相似文献

This paper investigates empirically the impact of inflation on the terms of trade, prices received and paid, for Greek farmers in the period 1967–87. According to conventional theory, inflation can have a non-neutral effect if it is unanticipated and if prices received and paid by farmers exhibit different degrees of flexibility. However, in the case where prices are administered, inflation neutrality depends on government's policy objectives and ability to adjust prices of inputs and outputs to the rate of inflation. The empirical investigation undertaken in this study shows that pricing policies implemented by the Greek government have resulted in neutralising the impact of inflation on the terms of trade for Greek farmers. Furthermore, the observed significant variability of the terms of trade can be attributed solely to real demand and supply factors.  相似文献

Agriculture looms large on the WTO's agenda. It was the first substantive item listed in the work programme of the Ministerial Declaration launching the Doha Round, and it was arguably at the centre of the failure at Cancun. Developing countries made it clear both before and during the Cancun meeting that progress on agriculture was their primary objective. Negotiations in other areas have received less attention and progressed more slowly. This paper considers that prioritisation, and suggests that the interests of developing countries in the current round of trade negotiations are much broader than is suggested by the narrow range of agricultural issues that have dominated negotiations. A true development round would require a significant reprioritisation of many areas of the WTO's current agenda.  相似文献

Mackay Whitsunday Safe Communities (MWSC) was developed using a capacity building model that consciously attempted to design sustainability into the network. Our aim was to quantify the flow of resources used by MWSC to implement and sustain its injury control activities. Resource exchange among network members was quantified and analysed using social network analysis. In 2004, MWSC accessed an estimated 6.5 full-time staff equivalents and $0.9 million. However, these resources were largely accessed externally. The linking relationships that connected MWSC to its external support network, more than half of which were maintained by six broker network facilitators, were the critical social asset used to access resources and sustain network productivity. The sustainability of this network and arguably similar safety promotion networks is vulnerable to the changing priorities of external sponsoring agents and highly dependent on its leaders who facilitated access to the resources it required to remain productive.  相似文献

Based on a simple model of compatibility choice under differentiated Cournot duopoly with network externalities, we consider how the levels of a network externality and product substitutability affect the choice of compatibility. In particular, if the level of network externality is larger than that of product substitutability, there are multiple equilibria involving imperfect and perfect compatibility. Furthermore, we demonstrate the conditions for constructing such a network alliance so that firms provide perfectly compatible products. The network alliance is stable and socially optimal.  相似文献

This paper aims to empirically examine how customer-induced variability, process variability, supply chain strategy, and business performance interrelate in a service firm context. Quantitative data were collected via a questionnaire-based survey. A total of 376 organizations responded and 313 responses were usable. This represents an adjusted response rate of 10.43 %. The survey results were analyzed by factor analysis, ANOVA, and regression models. The results provided the basis for testing the proposed model. They indicated a positive association between customer-induced variability and process variability. Since firms have different levels of variability, each firm will have a different strategic focus. The emphasis of that strategy will, in turn, result in greater flexibility and customer satisfaction. More specifically, firms with high and low levels of variabilities are suggested to focus on the cost- and flexibility-oriented strategies, respectively.  相似文献
