Demography or respect?: work group demography versus organizational dynamics as determinants of meaning and satisfaction at work.

This article tests two competing models of meaning and satisfaction at work. First, meaning and satisfaction at work can be influenced by the demographic composition of work groups, especially their racial and gender compositions. Second, meaning and satisfaction can be influenced by management behaviour, especially by leadership in maintaining a productive environment and by respect for workers' rights. We evaluate these determinants, along with more traditional determinants that focus on socio-technical characteristics, using a unique data set derived from content analysing the reports provided by book-length organizational ethnographies (N = 108). Work group composition is found to have only a minor and selective influence on meaning at work. In contrast, management leadership and respect for workers' rights are found to have much stronger and more widespread effects. The well established role of socio-technical factors such as job autonomy as foundations for meaning and satisfaction in work is also replicated in the analysis. When contrasted with both work group demography and traditional job and organizational characteristics, a well run organization is found to be the single most important underpinning for a meaningful and satisfying work life. In the concluding section we develop the implication of these findings for organizational analysis.

Success and future of demography: the role of data and methods.

Demography typifies paradigmatic success; that is, cumulative scientific work that has provided useful perspectives on a set of important questions. This success can be traced partly to the core subject matter of demography, which is relatively conducive to quantitative, observational science. The development of demography was further aided by extrinsic factors, such as the import of its data for government administration, for business purposes, and the import of demographic questions for social problems and public policy. These observations make suspect any simple projection of demography's success into the future or the transport of its experience to other disciplines.

Organizational demography.

This is a review of the literature concerning organizational demography, with a focus on intraorganizational demography. The author concludes that "the potential for organizational demography appears great, especially for yielding new insights into organizational behavior. There are also current linkages with internal labor market theory, and linkages with ecological and network theories that are beginning to emerge. New implications stratification theory and national opportunity structures, the dynamics of labor markets, and for research in aging are also indicated. From this review, we conclude that there is much to be gained from theoretical development at the interface of organizations and demography."

Health demography comes of age.

The U.S. health care industry has been hampered in the development of a mature marketing function in part due to characteristics unique to the industry. These characteristics include a lack of market data, poorly developed market research techniques, and a poor understanding of consumer behavior within the industry. Some of the deficiencies are being addressed through the development of an emerging field that is being referred to as "health demography." Health demography and those who have begun to refer to themselves as health demographers are drawing from the fields of demography, epidemiology, biostatistics, and the social sciences to formulate a new discipline uniquely related to the needs of today's health care marketers and planners. Those involved with health demography are developing databases and models for application to concrete problems in health care delivery. The development of this field is contributing to the advancement of the state of marketing in health care and serving to reduce many of the barriers that have retarded the development of a mature marketing function within the health care industry.

Demography of short-tailed shrew populations living on polychlorinated biphenyl-contaminated sites.

In ecological risk assessment, a key necessity is to understand how contaminants known to have negative impact on laboratory mammals affect the population demography of mammals living in their natural environment. We examined the demography of six local populations of the short-tailed shrew (Blarina brevicauda) living in eastern deciduous forest palustrine habitat along the Housatonic River (MA, USA) on soils contaminated with a range of polychlorinated biphenyl (PCB) concentrations (1.5-38.3 ppm). The objective of the study was to assess whether PCBs adversely affect the population demography of these small mammals living in their natural environment. Blarina were selected for study because they would be expected to readily bioaccumulate PCBs from the soil. Populations were intensively live trapped on 1-ha grids from spring to autumn 2001. There was no relationship between any demographic parameter and PCB soil concentrations. Densities were high (usually exceeding 20/ha, and on two grids exceeded 60/ha in summer); survival was good (typically 60-75% per 30 d); and sex ratio, reproduction rates, growth rates, and body mass were within the ranges reported in the literature. Thus, these shrew populations showed no detectable impact on their population demography from living on PCB-contaminated sites.

Demography of the Hadza, an increasing and high density population of Savanna foragers.

This is a report on the demography of the Hadza, a population of East African hunter-gatherers. In it, we describe the results of a census, and our estimation of age structure, survivorship, mean age of women at childbearing, number of live children, total population size and density, and rate of change since 1967. We show that relevant measures fit closely the stable population model North 6 chosen by Dyson to represent Hadza demography in the 1960s. We compare aspects of Hadza demography with surrounding non-Hadza and with the !Kung. Among other things, we find that the Hadza have a higher population density, higher fertility, and a faster population growth rate than do the !Kung. These demographic differences are consistent with our expectations, which were based on differences in the costs and benefits of foraging in the two regions. We also show that Hadza demographic parameters display remarkable consistency over the past 20 years. Since neighboring populations have been encroaching on the area used by the Hadza, and Hadza foragers have been subject to interludes of externally imposed settlement, this consistency is surprising. We discuss some of the implications.

5.1 The demography of oral diseases, future challenges and the implications for dental education.

This Section considered the immense challenges presented by the changing demography of populations (in particular, cross-boundary flow), changing oral and dental disease trends. It also considered the difficulties of gathering data on such information. It then considered how these challenges may affect the education of the dental team in the future. The Section considered the concept of the 'global village' as a representation of the changing world demography. We were at pains to recognize that our role was in considering both emerging and established market economies. In fact, a major part of the Section's activities concentrated on the development of the professional ethic of social responsibility - represented at the local, regional, national and international levels. We considered a finite group of oral and dental diseases, namely dental caries, periodontal diseases, oral cancer and cranio-facial disorders. In addition, we chose to comment on systemic diseases influenced by oral diseases, oral diseases influenced by systemic diseases and iatrogenic diseases (including prion disorders and cross-infection control issues). The Section recognized the profound difference between needs and demands in the provision of oral and dental health care. We considered the concept of best practices within our working remit and named these as: * the gathering of valid data on health trends; * uniformity in the measurement of disease and diagnostic parameters; * the identification of a core curriculum which best addresses an increased awareness of changing demography; and * a multidisciplinary approach to education and research in the context of global collaboration. The Section recognized the enormous potential for global networking with the explosion of information and communication technology. We investigated the requirements in converging towards higher global standards, while accepting and appreciating important regional and continental differences. To this end, the Section has put forward a number of important recommendations and realistic goals.

Urban housing demography.

"The purpose of this article is to review the literature in housing demography with emphasis on its geographic aspects." The differences among developed countries concerning patterns of home ownership are noted. "After a short discussion of households as the point of articulation between population and housing, I will examine interurban differentials in housing demography, review various population-oriented and housing-oriented approaches to intraurban housing demography, and finally, discuss the problems of and challenges for geographic research in this field."

[Social demography in Quebec: a preliminary account].

"The goal of this paper is to review those explanatory models that dominate social demography in Quebec. The classical organization of demography, which calls upon the three components of demographic reproduction--fertility, migration and mortality--is followed. The concluding part of the paper deals with the concept of 'demographic regime', which aims to bring the three components together into an overall theory of demographic reproduction. The paper shows that if the functionalist and empirical tradition (mostly American) has dominated the field of demography for a very long time, feminist and materialistic approaches have recently appeared for the interpretation of demographic realities."

[Demography of lung specialists in France].

INTRODUCTION: This article analyses the medical demography data in France, particularly the situation concerning lung specialists. METHODS: Study of the published data, particularly institutional reports (Ministry of Health, Sickness Insurance). RESULTS: The demography is characterised by important differences between specialties, regions, and salaried and private practice, as well as the effects of ageing and the increasing numbers of female practitioners. Lung specialists are, on average, younger and more evenly distributed between the different types of practice. Nevertheless they risk experiencing the same difficulties as other specialties in responding to the needs of the French population. The principle proposals of the public authorities concern the restriction of numbers, the regulation of established specialists and new methods of access to the speciality. CONCLUSIONS: Medical demography has a major role in the future of the French health care system.

Demography: the past 30 years, the present, and the future.

In a population, 30 years approximates the mean length of a generation or the time in which one generation replaces the previous one. In most areas of demographic research, one generation of research replaces the next in a considerably shorter period. A glance at what demographers were doing 30 years ago shows that in most areas, past research no more resembles what demographers do now than the Friedan calculators of that period resemble our current desktop computing environments. In these areas, current research differs from the research of 30 years ago in the theoretical approach, in the methods employed, and in the type of data used. Where great change has occurred, theory, methods, and data appear to have evolved together: each has changed in response to changes in the other areas and then has demanded further developments in those areas. Formal demography is one area that has been characterized by continuity. The questions addressed and the basic techniques employed build on a long heritage, even while steady progress is made in the development of methodology and analytic techniques. Analysis of the 1980s reintroduced the idea of context--the idea that behavior is influenced not only by the characteristics of individuals but also of the environment in which the behavior takes place. In the 1990s, this approach will be incorporated more thoroughly into theoretical developments in all areas of demography as we attempt increasingly to make comparisons across cohorts and time while continuing to model individual behavior. Mortality is the theoretically underdeveloped area of demography which probably will show the greatest change in the next 30 years.

The contours of demography: estimates and projections.

This paper considers the scope of demography and the various research approaches that legitimately could claim the label. As a small field lacking security in academic structures, demography has been unusually sensitive to demand factors, including those associated with perceived population problems. International health is cited as an area of increased demographic presence; reasons for this development are explored. The technology for performing research in demography is improving more rapidly than in many other areas of the social sciences, and thus is helping to improve the relative standing of the field. Taking a demand-oriented approach, the paper identifies several promising research areas in which demographers will be called on to address issues of national and international concern.
