The use of the passenger car is a major cause of environmental degradation and increasing congestion on traffic arteries. Policy‐makers therefore seek ways to curtail this form of private transport. Scientific research can help them attain this goal by identifying factors that influence travel behaviour. This paper examines the mobility of senior citizens with respect to various leisure activities, an area that has remained under‐exposed. The analysis shows that older people prefer to take the car for trips in their leisure time. If they own a vehicle, they tend to use it frequently, irrespective of where they live. Characteristics of the residential environment mainly influence the modal choice of seniors who do not have a car of their own. Public transport is primarily used as a substitute for walking and cycling; public transport does not offer seniors a real alternative to the car.  相似文献

We consider the history of woodland clearing in central western New South Wales, Australia, which has led to the present highly cleared and fragmented landscape. A combined approach is used examining available historical land‐use data and using regression analysis to relate the pattern of cleared and wooded areas in the recent landscape to environmental variables, taking into account the contagious nature of clearing. We also ask whether it would be possible to apply a simple simulation modelling approach to reconstruct a credible historical sequence of clearing in the study area. The historical data indicate that annual clearing rates have varied substantially in the study area and selective tree removal (ringbarking and thinning) has been common. These findings make it unlikely that a simple simulation approach would replicate the spatial and temporal sequence of woodland loss. Our regression results show that clearing patterns can be related to environmental variables, particularly annual rainfall and estimated pre‐European vegetation type, but that patterns are dominated by contagion.  相似文献

It is well known that home ownership has an impeding effect on migration. However, the strong increase in home ownership in the Netherlands since the Second World War has not led to a decrease in migration. In this paper three factors are identified which may counterbalance the expected negative effect of increasing home ownership on migration. First, the composition of the population of homeowners has changed towards younger, more mobile households. Second, home ownership has become more common, possibly leading to greater dynamics within the owner‐occupied segment of the housing market. And third, macro factors such as economic growth may have led to more migration. Using the Housing Demand Surveys and logistic regression analysis, we investigated to what extent the effect of home ownership on migration changed in the Netherlands during the 1980s and 1990s. We find – contrary to what we expected – that during the research period the negative effect of home ownership on migration seems to have strengthened somewhat. Within the research period, however, this negative effect was compensated by a general rise in migration for both owning and renting households, possibly attributable to macro factors affecting migration, such as economic growth and changes in the housing market.  相似文献

Estimating stature from skeletal remains in an archaeological context requires appropriate methods that take into account possible temporal and spatial changes in body proportions. New regression equations—both least squares (LSQ) and reduced major axis (RMA) equations—were thus developed for estimating living stature from the long bone lengths of medieval inhabitants (N = 60) of Westerhus, Sweden. The living stature of these skeletal specimens was determined by using the anatomical method. Findings in this study reveal that LSQ regression equations systematically overestimate statures of short individuals and underestimate those of tall individuals, whereas the RMA equations—both combined sexes and sex‐specific equation—provide more accurate stature estimations for individuals of very different statures. The combined sexes RMA‐equations should be used for cases in which the sex is unknown because they provide more accurate stature estimations than sex‐specific equation with a wrong sex determination. These new equations are more appropriate than generally used regression equations for estimating statures of the medieval period Scandinavians. Copyright © 2009 John Wiley & Sons, Ltd.  相似文献

The aim of this paper is to connect two processes that have been analysed independently to date and that have characterised the housing experience of the Spanish population. On the one hand, the consequences induced by the high density of Spanish urban spaces on other spatial spheres of people's lives and on the other hand, the traditional presence and the recent expansion of second home possession. In this context, we will demonstrate that, in Spain, a strong statistical relationship has been established between the location of main dwellings in a very dense urban context and a greater probability of having second homes. This relationship is better known in the scientific literature as the ‘compensation hypothesis’.  相似文献

Much can be learned about the religious ideology and mortuary patterns as well as the demographic and health profiles of a population from archaeological human fetal skeletons. Fetal skeletons are rare, however, largely due to poor preservation and recovery, misidentification, or non‐inclusion in general burial populations. We present an analysis of 82 fetal/perinatal skeletons recovered from Kellis 2, a Roman Period cemetery dated to the third and fourth centuries AD, located in the Dakhleh Oasis, Egypt. Most of the fetal remains were individually wrapped in linen and all were buried among the general cemetery population in a supine, east–west orientation with the head facing to the west. Gestational age estimates are calculated from diaphysis lengths using published regression and Bayesian methods. The overall similarity between the fetal age distributions calculated from the regression and Bayesian methods suggests that the correlation between diaphysis length and gestational age is typically strong enough to avoid the ‘regression’ problem of having the age structure of reference samples adversely affecting the age distribution of target samples. The inherent bias of the regression methods, however, is primarily reflected in the gestational age categories between 36 and 42 weeks corresponding with the expected increase in growth variation during the late third trimester. The results suggest that the fetal age distribution at Kellis 2 does not differ from the natural expected mortality distribution. Therefore, practices such as infanticide can be ruled out as having a significant effect on the observed mortality distribution. Moreover, the Kellis 2 sample is well represented in each gestational age category, suggesting that all premature stillbirths and neonatal deaths received similar burial rites. The age distribution of the Kellis 2 fetal remains suggests that emerging Christian concepts, such as the ‘soul’ and the ‘afterlife’, were being applied to everyone including fetuses of all gestational ages.

Thanks to pioneering work within anthropology, students of international migration acknowledge that most immigrants do not sever their ties with the homeland, but rather maintain them through a variety of cross‐border relationships. While scholarly work has proliferated, since the early 1990s, over the transnational economic and political activities of immigrants, to date, only few analysts have examined the religious practices with which immigrants sustain memberships in multiple locations. In addition, most available studies on transnational migration has dwelled on qualitative methods, such as participant observation, focus groups discussions and in‐depth interviews with a handful of informants, with little or no inclination towards the quantitative measurement of key variables implicated in the process. The prevalence of ethnographic methods in this area of research has, quite understandably, engendered charges of exaggeration, given the tendency of such techniques ‘to sample on the dependent variable’, to borrow the phrase of Alejandro Portes. Using data collected from a survey among Ghanaian immigrant congregations in Toronto, this study seeks to statistically predict the propensity to engage in transnational religious practices by way of a binary logistic regression analysis. In addition, the study examines how the transnational religious activities of the sampled immigrants relate to, overlap with, and differ from other kinds of transnational practices they pursue.  相似文献

Abstract

The authors reconstruct processes of ethnic identification among residents of rural northeast China from the end of the eighteenth century to the beginning of the twentieth through an analysis of naming behavior. They apply discrete-time event-history techniques to individual life histories compiled from longitudinal, nominative household-register data from state farms in what is now Liaoning Province to identify the individual and household circumstances associated with the adaptation of Han or Manchu names, focusing on the role of heredity and status. Ethnic identification in late imperial northeast China was potentially fluid. Many residents were descended from migrants from Shandong who became hereditary tenants on state land administered by a system of Manchu government known as the Eight Banners. As banner people, or qiren, these residents could legitimately claim to be Manchu. As descendants of Shandong migrants, they could also claim to be Han. They could express their choice of ethnic identity through their choice of names not just for their children but also for themselves. Names not only express ethnic self-identification, but their registration by state authorities in the analyzed data also implies official recognition and legitimacy. The authors' results demonstrate that ethnic identity was not hereditary but subject to individual and family choice.  相似文献

Online social networks (OSN) are major platforms of ICT‐enabled communication, supporting place‐independent social life. However, recent findings suggest that the geographical location of users strongly affects network topology. Therefore, OSNs may be simultaneously related to locations and also unlocked from offline geographies. Our paper addresses this dual‐faced phenomenon, analysing the location‐specific effect on OSN diffusion and OSN usage. Findings on iWiW (International Who Is Who), the leading OSN in Hungary in the 2000s with more than 4 million users, suggest that the rate of users (proxy for OSN diffusion) is positively associated with the geographical proximity of Budapest, the foremost urban centre in the country. On the contrary, the average number of connections (proxy for OSN usage) is independent of the geographical proximity of the capital, and it is even higher in peripheral regions when controlling for other offline factors.  相似文献
