A sequential selectivity model of the decisions of arbitrators

The study investigates arbitrator gender and grievant gender effects on the decisions of 146 arbitrators rendered on a hypothetical drug-testing case. The effects are estimated using a sequential selectivity model. This approach takes into account the sequential and conditional nature of arbitrators' decisions. The results indicate that arbitrators are more likely to overturn terminations when the grievant is female, and that female arbitrators are less likely to fully reinstate grievants when the termination is overturned. Other results include the finding that older arbitrators treated grievants more harshly by more often awarding only partial reinstatements. When suspensions are given, however, we find that older arbitrators award shorter suspensions than do younger arbitrators. It is also found that more experienced arbitrators awarded longer suspensions than less experienced arbitrators.     

Design considerations for neyman-pearson and wald hypothesis testing

Summary The Neyman-Pearson Lemma describes a test for two simple hypotheses that, for a given sample size, is most powerful for its level. It is usually implemented by choosing the smallest sample size that achieves a prespecified power for a fixed level. The Lemma does not describe how to select either the level or the power of the test. In the usual Wald decision-theoretic structure there exists a sampling cost function, an initial prior over the hypothesis space and various payoffs to right/wrong hypothesis selections. The optimal Wald test is a Bayes decision rule that maximizes the expected payoff net of sampling costs. This paper shows that the Wald-optimal test and the Neyman-Pearson test can be the same and how the Neyman-Pearson test, with fixed level and power, can be viewed as a Wald test subject to restrictions on the payoff vector, cost function and prior distribution.     

Tourism in Tropical Africa A review of literature in English and research agenda

Literature on tourism in tropical Africa is reviewed to indicate the current and future roles of tourism in tropical African countries. Attention is then directed to research issues whose investigation may lead to the development of guidelines for the extension, regulation, and management of tourism. These issues are arranged under the following headings: inventory, demand, types of tourism, economic impacts, socio-cultural impacts, environmental impacts, infrastructure, regional patterns, international cooperation, and tourism futures.     

Measuring Serious Leisure in Chess: Model Confirmation and Method Bias

The serious leisure inventory and measure (SLIM) was tested with 348 chess players to confirm the factors, assess the effects of method bias, and propose a set of the best-performing items for the 18 factor SLIM. The 54-item SLIM demonstrated acceptable fit and reliability values. The effect of method bias was evidenced in the sample and explained one-third of the variance. Inspection of factor loadings, when controlling for method bias, yielded one best-performing item per factor. Findings indicate method bias continues to be problematic for self-report measures such as the SLIM.     

Sample bias in contingent valuation: A comparison of the correction methods

Abstract

This article compares various methods for correcting contingent valuation aggregate benefits when the sample is known to be biased. A sample is defined as the population, and response rates are simulated on the basis of a measure of salience. The simulated response rates suffer from nonresponse bias and selection bias. Coefficient and benefit estimates that result from weighting and self‐selection correction approaches are compared with the true coefficient and benefit estimates. Our results indicate that at both low and high response rates the standard approach leads to bias, and either correction approach will reduce the bias in coefficient and benefit estimates.     

The environment‐community symbiosis: A case for collaborative tourism planning

This article advances the proposition that sustainable tourism can be achieved through recognition that the public and private sector, the host communities and the natural environment are interdependent stakeholders in a complex tourism ‘domain’, where no single individual, agency or group can resolve strategic tourism issues by acting alone. The planning and management of this domain for the purpose of achieving sustainability requires moving away from traditional approaches towards dynamic collaboration among the stakeholders of the tourism development and planning domain. Collaboration provides a flexible process which evolves over time, enabling stakeholders to disseminate and manage problems or issues on an interactive basis. It offers an attractive alternative to adversarial problem solving methods in tourism planning and management, when inter or multi‐sectoral participation is required. The paper commences with a discussion of the shortfalls of traditional tourism planning processes and models, followed by an overview of collaboration ‘theory’. Examples are given which illustrate collaborative approaches in several mountain resort areas. An exploratory case study of tourism development and planning issues in the mountain community of Canmore, Alberta (Canada) is then presented, leading to a discussion and conclusion regarding the theoretical and practical applications of collaboration toward achieving sustainable tourism.     

Procedural justice,ethical climate and service outcomes in restaurants

The literature suggests that ethical climate may actually contribute to organizational success by enhancing employee performance. Ethical climate is considered to be highly relevant to the hospitality industry, since it enhances service-providers’ contact with customers. This study reinforces previous researches by exploring the relationships between ethical climate, service, and customer satisfaction in restaurants. We have also examined the relationship between ethical climate and the fair treatment of employees by an organization. The study was conducted in 20 restaurants, with 171 employees and 103 customers. Data were obtained from employees, customers, and “mystery shoppers”. As expected, ethical climate was found to be related to service performance which, in turn, was found to fully mediate the relationship of ethical climate with customer satisfaction. Ethical climate was also found to correlate positively with procedural justice. Our results indicate the benefits of the ethical message conveyed through consistent managerial practices in service organizations.
