Contribution of low-level flammable vapor concentrations to dust explosion output

As a result of extensive dust explosion research, additional areas of hazards have arisen. The potential of combining small percentages of flammable vapors (below the lower explosion limit) introduces additional dust explosion hazards.     

Personal Attachment to the Union in Small Bargaining Units

Union member attachment research has generally examined large unions organizing large employers. The present study presents a conceptual model and related data concerning various aspects of the union attachment expressed by individuals in small bargaining units. The results show differences among individuals in commitment based on their union experiences and demographic characteristics. Résumé Les études traitant de la loyatué qu'éprouvent les membres envers leur syndicats examinent généralement des syndicats importants au sein d'entreprises de taille. La présente étude offre un modèle conceptuel et les données relatives aux divers aspects de la loyauté exprimée par des individus appartenant à de petites unités de négociations. Les résultats démontrent les différences de loyauté chez les membres selon leur experience syndicale et les caractéristiques démographiques.     

The timing of residential land development: A general equilibrium approach

A formal model of the development process is constructed in order to arrive at a better understanding of the land development process, the change in land prices over time, and the effects of public policy on these variables. The relationship between the rate of interest and the rate of price appreciation on land is shown to depend upon development costs, agricultural opportunity costs, market structure, and the level of Ricardian rents on land. The effects of a land tax and a capital gains tax on the rate of development are also analyzed.     

Corporate mergers and union wage premiums

Corporate mergers possibly enhance the labor negotiation advantage of employers. This study investigates the association between wage levels and merger activity to test the employer bargaining strength hypothesis. The results indicate significantly lower union wages as a consequence of merging. Merger activity, however, does not influence wage levels of non-union workers. These findings are supportive of the employer bargaining strength hypothesis.     

Compensating Wage Differentials with Unemployment: Evidence from China

We estimate the economic value of mortality risk in China using the compensating-wage-differential method. We find a positive and statistically significant correlation between wages and occupational fatality risk. The estimated effect is largest for unskilled workers. Unemployment reduces compensation for risk, which suggests that some of the assumptions under which compensating wage differentials can be interpreted as measures of workers’ preferences for risk and income are invalid when unemployment is high. Workers may be unwilling to quit high-risk jobs when alternative employment is difficult to obtain, violating the assumption of perfect mobility, or some workers (e.g., new migrants) may be poorly informed about between-job differences in risk, violating the assumption of perfect information. These factors suggest our estimates of the value per statistical life (VSL) in China, which range from approximately US$30,000 to US$100,000, may be biased downward. Alternative estimates adjust for heterogeneity of risk within industry by assuming that risk is concentrated among low-skill workers. These estimates, which are likely to be biased downward, range from US$7,000 to US$20,000.      

Ludic and liminoid aspects of charter yacht tourism in the Caribbean

The behavior of charter yacht tourists in the British Virgin Islands can be viewed as a symbolic expression and an inversion of the central sexual and social ideologies of the tourists' home culture. The paper analyses the behavior as a form of play, following Huizinga and Norbeck, and in terms of liminality and communitas, following Victor Turner. The conspicuously “anti-structural” mores and behavior allow the tourists licensed suspension of everyday rules, while reinforcing the latter. The tourists' image of the Caribbean as a sensual playground and the hosts' image of the tourists as self-centered and frivolous are established and perpetuated in this liminoid context.     

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.     

Leisure in Living Local through Food and Farming

This article reflects on aligning leisure research with the local foods movement while placing the local foods movement into the larger framework of sustainability and the fields of leisure and recreation. The local foods movement has persisted during difficult economic times; growth in local foods venues and young people endeavoring to establish small-scale sustainable farms continues to flourish. Given the history of leisure research and its continued success alleviating participation barriers and constraints, the need for leisure researchers to focus on local food systems is imperative and timely. This essay highlights the notion of leisure in living through local foods and the serious leisure aspects of small-scale sustainable agriculture. This article also encourages leisure researchers to explore and assess the relationships between the local foods movement and small-scale farming as embedded in the larger framework of sustainability.
