It is widely believed that work attitudes influence attitudes toward life overall. We investigated a multivariate model of work attitudes and overall life attitudes using survey data from two nationally representative (U.S.) data sets, one cross-sectional and one longitudinal. Including a comprehensive set of control variables, we found only weak support for the attitudes spillover perspective, suggesting that employees often compartmentalize or segregate their work and nonwork lives. We consider theoretical and practical implications of these findings.  相似文献

A recent paper (hereafter referred to as the Paper), Bermingham (2003), presented what appeared to be an analytical review of current situation of declining population growth rates in many parts of the world. The Paper suggested that the increasing growth rates before about 1970 constituted exponential growth, but that the currently declining growth rates were not exponential growth. Hence, the paper asserted that we should not use the terms exponential growth and doubling times in describing the current situation. Many of the suggestions in the paper are contrary to established mathematics. These suggestions are examined here in some detail.  相似文献

This paper explores the role and position of grandmothers in African-Caribbean families resident in Britain. The data used for this paper comes fromm a sample of 180 life-history interviews collected in 1995–1996 from three generations of Caribbean-origin people living in Britain and the Caribbean. Findings from this research suggest that African-Caribbean grandmothers resident in Britain have come to play a less active role within their immediate family compared to earlier historical periods. At the same time however, these grandmothers have come to take on a more a transnational emissary role for their family and kin located throughout North America and Europe. Caribbean-born grandmothers appear to be using more modern means for fulfilling certain traditional tasks like child shifting, story telling or acting as a social safety net. Using their agency African Caribbean-born grandmothers have been able to carve out new niches for themselves despite changes in family structure brought about by migration and settlement patterns in Britain.  相似文献

Exponential Growth and Doubling Times: Use of these popular population buzzwords of the last half of the twentieth century was fully justified by the growth rates of that period. However, those growth rates have now all but disappeared and so have the underlying reasons that those buzzwords made sense. Misuse of such expressions today costs credibility. Though the world's population growth certainly does remain vigorous and robust, creating many reasons for concern, nowhere today is growth projected as exponential. The essence of exponential growth is analyzed and distinguished from exponential curves, and non-exponential growth. Several types of current population growth are recognized, none being exponential. In periods of non-exponential growth, a Doubling Time calculated from a single annual growth rate is grossly erroneous and often absurd. Other standard measures of growth are needed. United Nations projections should include figures for percentage growth by 2025 and 2050.  相似文献

The crucial challenge for integrated analyses of socioeconomic systems is keeping coherence in their multidimensional representation. Our approach describes the hierarchical structure of socioeconomic systems using the profile of allocation of human activity over a set of compartments defined at different hierarchical levels (e.g., whole countries, economic sectors, individual households). Compartments are characterized in terms of intensive variables (intensity of both exosomatic energy flows and added value flows per unit of human activity) and the extensive variable Total Human Activity population. In this way, relations of congruence across hierarchical levels can be used to link non-equivalent analyses. That is, changes in demographic variables, economic variables, technical coefficients, indices of environmental loading, institutional settings, and social aspirations are no longer independent of each-other even if described within different scientific disciplines.  相似文献

This paper deals with a full range of sexual and reproductive behaviors among different tribes of Gypsies in Serbia. The examined traits include rates of fertility, mortality, age distribution, education, crime rates, and parental care. In addition, Gypsy traditions of culturally prescribed sexual behavior are also studied. It is found that Gypsy tribes employ different reproductive strategies, ranging from an extreme, for humans, r (reproductive) strategy to a more typical K (parental) strategy. The reasons bringing about these differences come from the Gypsies' readiness to adjust their behavior and reproduction in order to create the most favorable strategy in a given environment. This paper elucidates and contrasts the more typical r-selected Gypsies with a group of K-selected Gypsies living in a Serbian village.  相似文献

This paper presents a typology and qualitative model of causation for use in assessing the relative contributions of population growth to problems of pollution, lost biodiversity, and natural resource depletion. Population growth is placed in context as one of eight key driving forces that shape environmental quality today. It is treated primarily as an impact amplifier, along with technology. Root causes are traced to paradigmatic beliefs—especially anthropocentrism and contempocentrism—which find expression in unsustainable consumption patterns and designs of political economy.  相似文献

This study forms part of a general programme of research aimed at evaluating the quality of life in Rome. In particular, we have wished to analyse the way in which housing quality, measured with indicators of housing structure and utilization, intersects with the quality of urban livability, measured here only with indicators of social background, homogeneity and hardship referring to subjects living in the individual segments of the city. Groups of territorial areas, homogeneous by housing typology, were identified using multivariate data analysis and it was thus shown how particular typologies of household respond to this supply. From this emerged a particular model of development of the city in concentric bands, within which the originally differentiated households have tended over time to assume homogeneous characteristics.  相似文献

Just as we have a turn around manager to save a failing business organization, so it is held, we need a turn around perspective to retrieve the Earth from being in a deficit position. Hence the paradoxical emphasis upon the Earth as the business of the future. Two important distinctions are offered which together provide a new frame of reference for bonding the human and the Earth. The initiating event for the first distinction was a business conference whose purpose was to explore the emerging domain of ego energy. In a parallel way, it is proposed we explore the yet to be discovered domain of eco energy. With eco energy we open our narrowed human window to cosmic perception. With cosmic perception, the energy of the universe can flow through us. The second distinction is between looking at and seeing. Looking at refers to treating our world as a collection of objects. As a collection of objects the Earth can be processed as a series of business transactions. With seeing we relate to our world as a communion of subjects. Such seeing offers transforming power for the human and the Earth to engage in the dialogue of powerful listening and speaking on both individual and planetary scale. These two sets of distinctions are sounded like echo chambers against ten ecologically guiding statements. These ten guiding statements become a reality-testing, experiential framework. Such a turn around perspective offers a different vision to be operationalized in our individual, community, and business lives. Then we can see clearly and respond with eco energy to the Earth, the business of the future!  相似文献

The related terms, sustainable and sustainability, have become popular and are used to describe a wide variety of activities which are generally ecologically laudable. At the same time, the term compromise is heard more frequently because the needs of the environment often are in conflict with the needs of humans. A brief examination of the question of compromise shows that a series of ten compromises, each of which saves 70% of the remaining environment, results in the saving of only 3% of the environment. Judging from the ways in which the terms sustainable and sustainability are used, their definitions are not very precise, especially when compromises are involved. An attempt is made here to give firm definition to these terms and to translate the definition into a series of laws and hypotheses which, it is hoped, will clarify the implications of their use. These are followed by a series of observations and predictions that relate to sustainability.  相似文献

This paper presents an application of an innovative methodological tool for the integrated assessment of farming systems (Multi-Objective Multiple-Scale Integrated Representation). It describes the effect of rural development in parallel on economic and ecological reading at different levels: household, village, and the commune comprising 3 villages. Socio-economic and environmental indicators are organized into integrated packages across scales. This is an ex-post facto analysis of a program of rural development implemented in the Central Vietnamese uplands in 1995 by the central government with the collaboration of FAO. We conclude that two classic problems can only be faced by using an integrated analysis across levels: Large scale generalizations can miss important location-specific characteristics, and exclusive focus on location specific issues carries the risk of loosing the big picture.  相似文献

We bring the rapidly developing tools for analyzing society's metabolism to the attention of a scientific audience concerned with matters of population and, in a complementary fashion, we draw the attention of material and energy flow analysts to the role of population and population dynamics within their own paradigm. As an analytic framework, we use the classic IPAT-model that relates environmental impact (I), population (P), affluence (A), and technology (T). We relate the IPAT model to the tool commonly used in MFA, so-called environmental Kuznets curves, and re-analyze empirical data from various sources, for both affluent industrial and for developing countries, within these frameworks. We conclude that population and technology seem to dominate over affluence as far as environmental impact is concerned, but that both the IPAT and Kuznets models fail to take into account the intricate interdependencies among different socio-economic systems and the increases in their the economic, material and population exchanges. In effect, both models tend to underestimate the environmental impact and create too optimistic an image of dematerialization in affluent industrial countries.  相似文献

In the extensive litigation over school board liability for segregated schools, a great deal of attention has been focused on changes in school attendance areas. Evidence presented in several trials suggested that school boards have gerrymandered boundaries to keep some schools black and others white. Even though both district and appeal courts have found violations in attendance zone changes, there has been little other than anecodotal evidence to support these findings. In many cases the areas with the most changes in attendance boundaries are also the areas of rapid racial transition, but correlation does not necessarily mean causation. This case study examines boundary changes in Topeka and suggests that racial change in schools is more directly attributable to demographic shifts than to attendance boundary changes.  相似文献

Managed growth is a politically popular rallying point which offends no faction by insisting upon nonnegotiable limits. Subscribers to this philosophy focus upon short-run accommodations to growth which apparently mitigate its physical consequences. Managed growthers react to longterm numerical projections with rejection, if not outright hostility. They may be more amenable to quality-of-life rationales for population limitation evolving from the biophilia hypothesis and ecopsychology. These theories claim that our species needs to exist in proximity to untrammelled wilderness and a natural environment for psychic health and creativity.  相似文献

The Earths surface has changed considerably over the past centuries. Since the start of the Industrial Revolution in the early 1700s, humans from the Old World started to colonize the New World. The colonization processes lead to major changes in global land use and land cover. Large parts of the original land cover have been altered (e.g., deforestation), leading to extra emissions of GHGs to the atmosphere and enhancing global climate change. The spatial and temporal aspects are still not very well known. More and more global integrated environmental assessments concerning global sustainability require long time series of global change indicators, of which population is an important one. This study presents an update of the geo-referenced historical population maps for the period 1700–2000, part of the History Database of the Global Environment (HYDE), which can be used in integrated models of global change and/or global sustainability.  相似文献

The predominant reform tradition of centralizing suburban government to deal with problems of inequality in the distribution of local services has been attacked recently by a new school of thought often labelled New Political Economists. This school believes that the existing structure of local government can maximize citizen choice by allowing citizens to shop around between the level and mix of public goods and services offered by alternate communities. The term polycentricity has been coined to describe this situation. Critics of polycentricity believe that the resulting quasi-market would be unfair to low and moderate income suburbanites. This paper examines the actual extent of choice in service levels available to different income groups located in the suburban ring of six metropolitan areas. The extent of inequality in choice between different income groups is measured and the implications of these findings for the conflict between polycentric and centralizing reformers is discussed.The research reported in this paper was funded by the National Science Foundation, Grant Number SOC7705600  相似文献

This paper presents empirical data to validate two points. (1) An integrated analysis of societal metabolism bridges an economic view of changes in socioeconomic systems with a biophysical representation of them. To obtain this check, it compares a biophysical indicator of development BEP with 24 traditional indicators of material economic development. The comparison covers a sample of 107 countries of the world, comprising more than 90% of the total world population (year 1993). (2) The concept of societal metabolism is useful to make biophysical analysts aware of constraints implied by economic viability and to make economic analysts aware of constraints implied by biophysical viability. To prove this point three practical examples of misunderstanding in the field of sustainability analysis are discussed.  相似文献

Natives often fear labor market competition of foreigners, as they may induce declining wages and rising unemployment as in the case of natives and immigrants being substitutes. However, there is also the potential that they are complements, producing positive wage and employment effects. This issue is examined in a framework with two types of labor, such that low qualified native and immigrant workers (blue collar), although substitutes for one another, are potentially complements to high qualified native workers (white collar). This is thought to accurately reflect the past West German immigration experience. Examining the wage functions of white and blue collar natives in a random effects panel model using a vast sample of micro data, we actually find that foreigners negatively affect the wages of Germans on the whole. Relatively small gains are made by white collar employees with less than 20 years experience, but these are outweighed by the larger negative effects experienced by blue collar employees.We wish to thank Don DeVoretz, Riccardo Faini, Andrea Ichino, and participants at the following 1993 conferences for their valuable comments where drafts of this paper were presented: The Economics of International Migration: Econometric Evidence at the University of Konstanz, Internationale Migration und Arbeitsmarkt der Schweizerischen Gesellschaft fur Statistik und Volkswirtschaftslehre at the University of St. Gallen, Adjustment Policies in Previously Centrally Planned Economies: Which Lessons from Developing Countries Experiences at the University of Brescia, and Congress of the European Society for Population Economics in Budapest. Substantial revisions were made following the valuable suggestions of two anonymous referees and the special issue editor Wolfgang Franz, for which we are grateful.  相似文献

Population projection models that are conceptually simple enough to be called transparent may be used to check the validity of projections generated by black box models whose behavior may be somewhat shrouded in mystery. This paper adopts a multiregional demographic model to illustrate how such a validation procedure might be carried out on state population projections produced by the U.S. Bureau of the Census in 1988.  相似文献

Immigration and internal migration “flight”: A California case study   总被引:2,自引:0,他引:2  
Recent analyses of 1990 census migration data have pointed up disparities in the way immigration and internal migration contributions affect an area's demographic profile. They show that there is little overlap between states with large population gains from internal migration from other parts of the United States and states with large population gains from immigration from abroad. This emerging pattern, along with the fact that immigration and internal migration select on very different demographic characteristics, could lead toward a demographic balkanization of the nation's population. This paper evaluates immigration-induced out-movement from California, based on an analysis of recently released migration data from the 1990 U.S. census. The results presented here suggest that California's out-migration consists of two different migration systems: first, an immigration-induced flight that exports lower income and less-educated Californians, primarily, to the nearby states of Washington, Oregon, Nevada and Arizona. And second, a more conventional migration exchange with the rest of the United States that involves the redistribution of better educated, higher income migrants. It is the former migration system which appears to be most responsive to the low-skilled immigration flows, while the latter should be responsive to more conventional labor market employment characteristics. This implies that, irrespective of changing economic conditions in the state, the continued immigration of low-skilled migrants will lead to more losses of native-born internal migrants to neighboring states and metropolitan areas. However, these migrant streams will not be made up of the best and brightest residents that characterize most conventional migration streams.A longer version of this report with more extensive background statistics isResearch Report 94–306 (Frey, 1994b) available from Publications, Population Studies Center, The University of Michigan, Ann Arbor, MI 48104.  相似文献
