Labour Intensification, Work Injuries and the Measurement of Percentage Utilization of Labour (PUL)

Labour intensification has often been assumed to be related to industrial safety, but surprisingly different views of this relationship have been held and systematic enquiry is lacking. A measure called the percentage utilization of labour (PUL) claims to monitor the intensity of labour in British manufacturing and therefore potentially affords the opportunity for a much more systematic investigation into the effects of labour intensity on industrial safety than has ever been possible before. This paper introduces the PUL measure and indicates why it might be thought particularly likely to register an increase in the 1980s. It then examines variation in PUL and in industrial injury rates in British manufacturing, both in the early part of the 1980s and over a longer period, in order to assess whether changes in PUL have tended to be associated with changes in safety. No consistent relationship is found. The evidence presented is reviewed, and the relationship between industrial injury rates, intensification of labour and the adequacy of the PUL measure for safety research is reconsidered.     

Redefining the Recruitment Niche for the Guide Association in the United Kingdom

This article shows how the concept of a recruitment niche can be valuable in understanding the difficulties the Guide Association in the United Kingdom has in recruiting new volunteers. Understanding Guiding as career volunteering, within serious leisure, shows how the distinctive ethos of the existing volunteers contributes to the social construction of the recruitment niche. The defining boundaries of the niche restrict the ability to recruit new volunteers. Thus the article gives an example of how a recruitment niche for a voluntary organization can be defined using the socially constructed ethos of volunteers involved in career volunteering rather than by characteristics such as level of educational attainment. It also demonstrates the implications of this for voluntary organizations wishing to increase recruitment.     

Tourism and crime: A conference

This conference did not solve the problem of crime in tourist-recreation destination regions. It did, however, allow interested participants an opportunity to inventory and generalized the crime problems and prospects as they related to a few destination regions in the Southeast. Differing criminal laws, law enforcement, gun-control laws, sentencing practices, and jury selection leave little doubt as to the truth of the statement that punishment for a crime is dependent on where the crime takes place. ∠ Further study of deceptive crime statistics and criminal characteristics for rural America is a much needed research goal for the planning and design of more viable tourist-recreation destination regions.     

Comparative North American and European gateway logistics: the regionalism of freight distribution

The global freight distribution system has been impacted by convergence in terms of technology, infrastructure, modes and terminals. Still, in spite of strong converging forces, it can be argued that logistical practices are far from being uniform. This paper analyses the regionalism in freight transport systems by providing a comparative analysis of gateway logistics practices in North America and Europe. It is demonstrated that Europe and North America are not walking the same paths when it comes to the configuration of transport and logistics networks, via operational decisions and the setting of a regulatory framework. The attributes of gateways, corridors, hinterlands, regulation, governance, value chains and labor provide an analytical framework to understand the regionalism of freight distribution in the North American and European contexts, as well as anywhere else.     

Estimating social travel demand of senior citizens in the Netherlands

Like many other countries, the Netherlands is experiencing a sharp rise in the ageing population. As age increases, people’s mobility may decrease. However, older people have more leisure time compared to their younger (working) counterparts, and potentially spend more time on social activities. Therefore, this group can possibly increase social travel demand. However, to date, the travel demand for social activities of senior citizens has received only little attention. This paper studies trip-making for social purposes, with a special focus on the demographic ageing factors. Using social activity diary data, models are estimated to predict the number of social trips, the travel distance and mode of transport for social trips. The results indicate that the elderly of today seem to be as mobile as their younger counterparts with respect to the number of social trips. High education and involvement in clubs on average result in more social trips and full time work is found to result in fewer social trips. With regard to trip distance the results show that the average travel distance does not decrease as people get older. Full time work is found to result in longer social trips. Shorter trips were found for people in urban as well as rural areas. Trips for the purpose of visiting or joint activities tend to be longer than average. With regard to transport mode choice the results indicate that older seniors (75+) are less likely to choose the bicycle, relative to driving. No other significant age effects were found. Significant effects were found for gender, household structure, education level, car ownership, having a disability, urban density, distance and the purpose of the social activity.     

Pyrrho's lemma,or have it your way

A simple lemma is derived to support the claim that regression models can be manipulated to a very large extent: by simply adding one regressor one can obtain essentially every set of desired regression coefficients and predictions as well ast-values and standard errors. Consequently, if the product of a specification search is not shown to be generalizable, a sceptical attitude towards its validity is well-founded.     

Equally Weighted Portfolios of Randomly Selected Stocks and the Individual Investor

The article contrasts 500 randomly formed equally weighted portfolios (1/N) to 221 actively managed stock funds, individual stocks, and the IBrX-50 index, representing indexed stock funds, considering transaction costs. The sample are the 50 stocks in IBrX-50 index in January 2007 throughout 60 months. Investors are likely to achieve greater returns and return-to-risk ratios with a randomly formed 1/N portfolio than with a stock fund, particularly those targeting retail investors, or one of the 50 stocks also randomly drawn. These portfolios would also outperform the IBrX-50. Robustness tests with variations in size and frequency of rebalancing do not change conclusions.
