Resource-based view research plays a prominent role in strategic management studies. In this paper we investigate the relativistic interpretation of the 'scarcity' concept, the appropriability of complementary resources, the measurability of the contribution that a specific resource brings to the overall value of the firm. The theoretical issues have been made context specific trying to show (a) how a not-scarce complementary resource like movie theatres can help build value for the distributor, mainly through the creation of reputation for the subsequent TV broadcasting; (b) that this resource can be appropriated from different companies; (c) that companies can develop different kinds of interfirm relationships in order to control complementary resources; (d) that reliable and valid parameters can be provided to measure the value of resources and the related degree of control from the distributors. Supporting empirical evidence is provided and implications for managing complementary resources are discussed.  相似文献

A method for constructing asymmetrical (mixed-level) designs, satisfying the balancing and interaction estimability requirements with a number of runs as small as possible, is proposed in this paper. The method, based on a heuristic procedure, uses a new optimality criterion formulated here. The proposed method demonstrates efficiency in terms of searching time and optimality of the attained designs. A complete collection of such asymmetrical designs with two- and three-level factors is available. A technological application is also presented.  相似文献

The present study was designed to investigate stability and changes in prosocial behavior and the parent and peer correlates of prosocial behavior in rural adolescents. Participants were from a rural, low SES community in the Eastern United States. The participants were in 7th, 8th, and 9th grades at Time 1 and 10th, 11th, and 12th grades at Time 4, and completed measures of prosocial behavior and quality of parent and peer relationships. Latent growth curve modeling revealed that despite moderate stability in individual differences in prosocial behavior and slight increases in quality of peer and parent relationships, level of prosocial behavior declined until late high school with a slight rebound in grade 12. Furthermore, increases in the quality of peer relationships predicted decreases in prosocial behavior for girls but not boys. Discussion focuses on continuity and change in prosocial behavior and the gender‐based relations between quality of parent and peer relationships and prosocial behaviors in adolescence.  相似文献

This study examined the concurrent and construct validity of the OMNI-Cycle Rating of Perceived Exertion (RPE) Scale, using elderly men and women. Seventy-six participants performed a load-incremented cycle-ergometer exercise test. Concurrent validity was determined by correlating OMNI-RPE responses with oxygen uptake, relative peak oxygen uptake, pulmonary ventilation, heart rate, respiratory rate, and respiratory-exchange ratio during a load-incremented cycle-ergometer protocol. Construct validity was established by correlating RPE derived from the OMNI-Cycle Scale with RPE from the Borg (6-20) Scale. Multilevel, mixed linear-regression models indicated that OMNI-RPE distributed as a significant (p < .05) positive linear function (r = .81-.92) for all physiological measures. OMNI-RPE was positively (p < .01) and linearly related to Borg-RPE in elderly men (r = .97) and women (r = .96). This study demonstrates both concurrent and construct validity of the OMNI-Cycle RPE Scale. These findings support the use of this scaling metric with elderly men and women to estimate RPE during cycle-ergometer exercise.  相似文献

The article describes the recent evolution of the Italian third sector, focusing particularly on its changing role in relation to welfare policies and on its contribution to the development of the provision of social services. In contrast with those considering the emergence and development of the sector solely, or mainly, as a consequence of decisions made by external actors, especially public institutions, the article shows a more complex and dynamic picture. The article demonstrates that the Italian third sector, although at the present time largely engaged in contractual services with the public sector, has maintained a level of autonomy that allows for continuous innovation both within and external to the social service sector. The Italian case supports the need for further debate on the role of the third sector in modern society.  相似文献

Terrorism presents a significant risk that is often approached at public policy, infrastructure, or emergency management level. Public perceptions of the likelihood of terrorist events, and how this may relate to individual preparedness, are not always extensively examined. The tendency to think that negative events are less likely to happen to oneself than to the average person is known as optimism bias. Optimism bias is relevant to perceptions of terrorism, because it is thought to be related to a reduction in precaution use. Using an online survey of 164 participants, this study aimed to determine whether Sydney residents thought they had a lower likelihood of experiencing terrorist events than other Australians. Significant optimism bias was observed for witnessing terrorist events, but not for personally experiencing terrorist events. In addition, Sydney residents tended to think that terrorist attacks were more likely to occur in Sydney than another major Australian city in the next five years. At the same time, household and workplace preparedness for terrorism was quite low, as was awareness of emergency strategies in the central business district. Perceptions of high likelihood of terrorism happening in one's own city, yet low preparedness present a challenge for risk communication and emergency management strategies. The diversity of possible terrorist targets, and the simple plans that can moderate the effects of a disaster may need to be emphasized in future anti‐terrorism initiatives.  相似文献

Previous work on adolescents’ disclosure has focused on the frequency of disclosure to parents, but not the quality of that disclosure. Therefore, there is a need to examine factors that predict the quality of adolescents’ disclosure, as well as the consequences of the quality for adolescents’ outcomes. In this study, 100 adolescents (M age = 14.27 years; 57 girls; 70.7% White, European American) disclosed to mothers a recent past event in which they felt excluded; the videotaped and transcribed conversations were rated for indices of the quality of disclosure (i.e., the quality of elaboration and emotion discussed). Adolescents completed measures of sociomoral behavior and parental warmth and mothers completed measures of their moral identity, circle of moral regard, and moral socialization. The quality of adolescents’ disclosure was related to adolescents’ sociomoral outcomes (including prosocial behaviors, empathy, and sociability). Adolescents’ disclosure quality was predicted by gender and by aspects of mothers’ moral sophistication. Findings highlight the importance of high‐quality self‐disclosure by adolescents for promoting adolescents’ moral development, potentially because such disclosure gives parents the opportunity to help adolescents cope with challenging peer experiences potentially through emotion coaching and problem‐solving. Moreover, the findings are novel because they highlight how maternal moral processes might promote adolescents’ disclosure.  相似文献

This paper analyzes alternative pricing schemes for funding investment in climate policies. This paper proposes a new policy scenario, explicitly disentangling the issue of burden sharing of financing new investments from the issue of taxation energy consumption and therefor emissions. We compare traditional allocation schemes with an optimal Ramsey pricing by applying demand elasticity values, derived from empirical estimations of household behavior for the 106 leading countries in the world, representing around 90% of total world energy consumption and carbon emissions in 2014. We calculate country-specific alternative taxation options: uniform, equitable and Ramsey pricing schemes, applied to households, assessing the related welfare effects. Our results show that the optimal pricing scheme, for a given investment need, can improve world welfare at the expenses of equitable considerations. In addition, the aggregate societal benefit outweighs the losses associated with specific group of countries, paving the way for easier political agreement, using compensation schemes to redistribute the proceeds.  相似文献

In this study, we report the results of an action research project whose aim was to develop and implement an operating room scheduler at the Meyer University Children’s Hospital. The study offers insights into the features that make an MSS optimisation model and scheduler effective and easy to implement, and shed light on those actions facilitating their introduction and use. Specifically, it suggests that creating an effective operating room scheduler requires clustering patients in homogeneous surgery groups and developing a flexible tool that allows: scheduling surgery groups instead of actual patients, easily adding/removing constraints, changing the objective function(s) and adjusting the planning horizon. In addition, it posits that gaining the commitment of top management by showing credible preliminary results, inferring stakeholder preferences by letting them comment on tentative schedules, introducing changes gradually and involving staff at lower levels of the hospital hierarchy can significantly facilitate the scheduler development and implementation.  相似文献
