Safety programmes in the Egyptian construction industry

This study is aimed at exploring the nature of the safety programmes applied by large-size contractors operating in Egypt. Results revealed that safety programmes applied by those contractors were less formal than the programmes applied by their American counterparts. Only three contractors out of the surveyed sample had accident records broken down by projects, provided workers with formal safety orientation, and trained safety personnel on first-aid. The study recommended that reforms to the scheme of the employers' contribution to social insurance are necessary. This is meant to serve as a strong incentive for safety management.     

The perverse effect of environmental regulation on emissions: The role of product-mix changes

We study the effect of environmental regulation (taxation) on emissions when the only available abatement method consists of product-mix changes. Firms choose to produce one or both varieties of a product—a pollution-intensive (dirty) and a non-pollution-intensive (green)—and compete in a differentiated Cournot duopoly. We characterize the equilibrium market structure as a function of the tax rate and show that increases in the tax can promote product-mix changes that lead to a jump in emissions for some tax range, an effect we call the perverse effect of taxation. Our work emphasizes the key role horizontal product differentiation in this process and shows that the perverse effect does not require the presence of vertical product differentiation. Further, the perverse effect of taxation is especially strong in the presence of incomplete regulation, that is, when only one of the markets is subject to taxation.     

The Effect of Social Cues on Sniping Behavior in Internet Auctions: Field Evidence and a Lab Experiment

This research explores how social cues presented in an online auction affect sniping behavior. Sniping is a strategy of placing a bid on an item in the very ending stages of an auction with a pre-determined ending time in an attempt to win the auction. Such a strategy conceals the intentions of the bidder until the last moments of the auction and minimizes the possibility of other opposing bidders submitting higher bids due to the short period of time left to respond. The research includes two field studies and a lab experiment indicating that sniping appears to be influenced by social factors, that is, when there are a greater number of bidders in the auction or the auction site provides social information about the bidders, the relative use of sniping increases. This research supports the perspective that bidders rely on others' bidding behavior and characteristics as an indication of the true value of the item on sale, and is one of the first studies in the literature which takes this perspective.     

Clothing as an environment for older adults' successful ageing

This research tested a conceptual model for proximity of clothing to self (PCS) in relation to age identity, self‐actualization, psychological well‐being, self‐assessed health, sex and chronological age among older adults, aged 65 and over, within the human ecological perspective. A mail survey was sent to a national random sample of 1700 older adults in the US resulting in 195 usable respondents in the final sample. The respondents returned two completed questionnaires, which were (1) Clothing: A Resource for Successful Aging? (to measure PCS, age identity and demographic variables) and (2) Personal Orientation Inventory (to measure self‐actualization). The results indicated that older adults' psychological well‐being, one component of successful ageing, was directly affected by their self‐assessed health, age identity and self‐actualization. PCS indirectly influenced individuals' psychological well‐being in a slightly negative way in later life. In sum, clothing may be used as a needs satisfier for different levels of needs or related more closely with needs in addition to self‐actualization needs for older adults. Further research should be conducted to explore relationships among PCS, different levels of human needs, clothing‐related variables and psychological well‐being for this age group. In practice, the effort should be given to teach the use of clothing (or other human‐built objects) as a tool or need satisfier to contribute to success in a person's later life by offering some educational or training programmes through local senior community centres or universities.     

A review of research on personality in teams: Accounting for pathways spanning levels of theory and analysis

Over the last half century there has been a great deal of interest in the role of personality in teams. In this article we review the theoretical and empirical research on this topic to summarize what we have learned and also to provide a foundation for future research necessary for application of this knowledge to human resource management decisions. We describe research that emphasizes both team- and individual-levels of analysis and theory, and we discuss recent efforts that attempt to bridge these two levels. We conclude by identifying several issues that should take precedence in research in order to advance our understanding of the role of personality in teams.
