Since the turn of the century, independent sales contractors have emerged as an important and growing sales and distribution channel. This study, guided by theories of attitude-behavior relation, constructs and tests a conceptual independent sales contractors (ISC) relationship quality scale. The findings support the proposition that relationship quality is a composite of attitudes and behavioral intentions. The work provides theoretical and practical implications, as well as suggestions for future research.  相似文献

Snowboarding is quickly becoming a popular sport at alpine resorts. In contrast to alpine skiing, where injuries to the knee and thumb are most common, the wrist (and forearm) and ankle are the most frequently injured body regions for snowboarders. Unfortunately, the rapid international growth of the sport has not been matched by detailed epidemiological evaluation of the injuries specific to snowboarding or the countermeasures to prevent them. The aim of this paper is to critically review the literature describing injury prevention measures, or countermeasures, for snowboarding. In doing so, it provides an evaluation of the extent to which these countermeasures have been demonstrated to be effective or associated with the occurrence of new types of injuries. Few countermeasures specific for snowboarding were found to have been formally evaluated. The countermeasures to which some attention has been paid are boots, bindings, wrist guards, skill level and methods of falling. Skill level and the other injury countermeasures apply more generally across the sport. Recommendations for countermeasure implementation include: education for snowboarders, adherence to snow conduct and safety codes, preparing snowboarders for their activity and maintenance of parks and runs. Recommendations for improved data collections include: standardising and maintaining existing data collections, collecting information about equipment used by snowboarders and monitoring injury trends. Further biomechanical and epidemiological research needs to be undertaken on knee/ankle and wrist/forearm injuries. Evaluation of countermeasures needs to keep pace with the rapid developments in this field. Particular attention should be directed towards evaluations of the role of wristguards, boots/bindings, fall technique and lessons in preventing injuries. Given the rapidly increasing popularity of the sport, the need for the safety equipment to be evaluated would seem to be a priority, along with identification of the mechanisms of injury.  相似文献

In this study, we assessed the epidemiological patterns of suicide terrorism in the civilian population of Pakistan. Information about suicide terrorism-related events, deaths and injuries was extracted from the South-Asian Terrorism Portal (SATP) for the period from 2002 to October 2009. Of 198 events, civilians were involved in 194 events. Civilians accounted for 74.1% (N = 2017) of those who died and 93.8% (N = 6129) of those who were injured. In nine districts, mortality rates were more than one death per 100,000 inhabitants per year. The yearly trend showed a shift of attack targets from foreigners and sectarian targets in 2002–2005 to security forces or general public in 2006–2009. Attacks on public installations (mosques) or political gatherings resulted in a significantly greater (P ≤ 0.02) number of deaths (22 vs. 8) and injuries (59 vs. 24) per event compared with security installations. These results show that prevention might focus on political negotiation with armed groups and that appropriate measures should be taken to protect mosques and political gatherings.  相似文献

The area of maintenace management has been placed under increasing pressure because of changes in the manufacturing production planning and control systems. In the last few years plant management has been asked to respond to productivity and quality challenges unmatched in business history. The maintenance department plays an important, indeed vital, role in the attainment of improved levels of productivity and quality.This article examines the relationship between production and maintenance management systems. A conceptual model is developed that integrates the preventive and corrective aspects of maintenance planning with the priority and capacity activities of the production planning system. The model assists management in scheduling maintenance craft labor for additional efficiency and effectiveness.  相似文献

The Parent Supervision Attributes Profile Questionnaire (PSAPQ), developed to measure aspects of caregiver supervision and protectiveness and previously applied within playgrounds and in the home, was modified for implementation in a beach setting. To assess the test-retest reliability of the PSAPQ beach modification (PSAPQ-BEACH), 20 caregivers completed the PSAPQ-BEACH twice, over a mean interval of 18 days (range 10-24). The test-retest reliability and internal consistency of the PSAPQ-BEACH scores were compared to those of the PSAPQ. All scores on the PSAPQ-BEACH were higher than the PSAPQ, providing evidence that the questionnaire remains reliable after its adaptation to beach settings.  相似文献

A significant body of literature has raised the possibility that portfolio outperformance based on a simple accounting‐based investment strategy can persist through time because markets may ignore and potentially misinterpret financial market signals. Employing a fundamental‐based strategy, we show that superior performance can be earned consistently through time by identifying and investing in firms with more favourable performance and credit signals. The strength of these portfolios are additionally characterised by the ability of the strategies to avoid firms with poor future prospects. These findings are robust across varying time periods after both transaction costs and related market constraints are considered.  相似文献

IMP researchers have examined conflict as a threat to established business relationships and commercial exchanges, drawing on theories and concepts developed in organization studies. We examine cases of conflict in relationships from the oil and gas industry's service sector, focusing on conflicts of interest and resources, and conflict as experienced by actors. Through a comparative case study design, we propose an explanation of how actors manage conflict and manage in conflict given that they tend to value and maintain relationships beyond episodes of exchange. We consider conflicts in relationships from a network perspective, showing that actors experienced these while adapting to changes in their business setting, modifying their roles in that network. By identifying conflict with the organizing forms of relationship and network, we show how actors formulate conflict through pursuing and combining a number of strategies, distributing the conflict across an enlarged network.  相似文献

Evolutionary economists have tended to assess firms and industries separately, neglecting the role of their interaction in the process of economic growth and development. We trace the separation of firms and industries to the introduction of population thinking in the discipline of industrial economics, including some broadly evolutionary analyses. If researchers conflate a population of firms with an industry, they introduce “thin” means of relating firms to one another and to industries. Despite his device of the ‘representative firm’, Marshall develops “thick” means of relating firms to industries by means of their internal and external organizations. Penrose avoids the notion of industry by focussing on heterogeneous and potentially mobile firms. Young and Steindl develop mundane explanations of firms’ relations within groups and locate the impetus for economic growth in a poorly understood environment. We conclude that evolutionary economists should revisit firms’ boundaries, not in the sense of explaining the existence of firms but in a relating and communicating sense in which boundaries signify the selective means of firms’ relationships.  相似文献

Empirical tests have produced mixed support for a membership-performance link in strategic groups, perhaps due to incomplete treatment of industry forces. We argue that strategic group concept is more useful for explaining performance differences among firms in some industries (where conditions favour conformity in firm conduct) than others. Using three industry structure constructs as criteria, 47 four-digit SIC industries are classified into ‘conforming’ or ‘non-conforming’ industry samples. Firms are then clustered into strategic groups in a separate treatment for each sample. Performance differences among groups are tested under conforming and non-conforming industry conditions. Tests confirm membership effects on ROA and ROE are significantly stronger in ‘conforming’ industries, where stronger regression relationships between conduct variables and performance also obtain.  相似文献
