Due to its manifold impact on the environment private car use represents an important dimension of environmental behavior in industrialized countries. Obviously, private car use is related to demographic characteristics of households such as the life-cycle stage and the living arrangement the household lives in. In addition systematic regional differences of private car use have to be taken into account. In this paper a causal model is derived, which aims to explain regional differences in car ownership and car use by regional demographic differences and region-specific control factors such as the car technology and institutional factors. Using aggregate data from a household survey in Austria and data from Austrian official statistics causal effect coefficients are then estimated. By applying path analysis the estimated effects of regional demographic characteristics on region-specific car ownership and car use can be decomposed into direct and indirect effects, with the latter effects being mediated by the control factors. Except for the average age of household heads and population density no significant direct demographic effects on regional patterns of car ownership and car use can be found. Car ownership and car use are best predicted by using the considered control factors as predictor variables. Nevertheless, many of the presumed indirect effects turn out to be of importance since demographic factors are closely linked to measures of regional institutional settings like per capita income, ownership of house/apartment and net commuting index.  相似文献

Age at first marriage, after controlling for socio-economic and demographic variables, varies across regions and districts. A geo-additive hazard model allows for measuring spatial effects. The nonlinear and baseline effects are modeled by Bayesian penalized splines; spatial components are treated as correlated random effects following a Markov random field. Application is based on data from 1999, 2003, and 2008 Nigeria Demographic and Health Surveys. Age at first marriage is positively associated with education and urbanization and depends on religion. It presents a north-south divide.  相似文献

Variations in fear of crime and behavioral restrictions were explored within city and suburban neighborhoods of the Chicago metropolitan area. A random telephone survey (n=1,803) gathered information on fear and behavioral restrictions, other crime-related experiences and perceptions, perceptions of the neighborhood physical and social environment, and demographic characteristics. These data were supplemented by merging contextural information (from census and other archival sources) about each respondent's place of residence to the data set. Hierarchial step-wise regression analyses were performed separately for the city and suburban residents. Sets of predictor variables were found that accounted for more than 25 percent of the variance in the criterion measures. Implications of these findings for policy makers and future research are discussed.  相似文献

Examining the Impact of Demographic Factors on Air Pollution   总被引:9,自引:0,他引:9  
This study adds to the emerging literature examining empirically the link between population size, other demographic factors and pollution. We contribute by using more reliable estimation techniques and examine two air pollutants. By considering sulfur dioxide, we become the first study to explicitly examine the impact of demographic factors on a pollutant other than carbon dioxide at the cross-national level. We also take into account the urbanization rate and the average household size neglected by many prior cross-national econometric studies. For carbon dioxide emissions we find evidence that population increases are matched by proportional increases in emissions while a higher urbanization rate and lower average household size increase emissions. For sulfur dioxide emissions, we find a U-shaped relationship, with the population-emissions elasticity rising at higher population levels. Urbanization and average household size are not found to be significant determinants of sulfur dioxide emissions. For both pollutants, our results suggest that an increasing share of global emissions will be accounted for by developing countries. Implications for the environmental Kuznets curve literature are described and directions for further work identified.  相似文献

Studies examining relationships between demographic variables in a general population of psychiatric outpatients and quality of life (QOL), in which QOL was assessed according to current recommendations, have not been performed yet. The aim of this study was to examine one particular aspect of this relationship: the question to what extent QOL scores can be predicted by demographic variables. In a sample of adult Dutch psychiatric outpatients (n=495), demographics were recorded and the participants completed a questionnaire for measuring QOL (WHOQOL-100). The relationships of the demographic variables with the WHOQOL-100 domains Social Relationships and Environment, were stronger than those with the domains Physical Health and Psychological Health. The latter had only significant relationships with educational level and sick leave, which explain little of the variance of the concerning QOL domain. In general, the demographic characteristics used, explained only a relatively small part of the variance in QOL scores. An exception was sick leave, which, in participants with a job, explained an extensive part (27.4%) of the variance of scores on the domain Physical Health.  相似文献

Aging and Life Satisfaction   总被引:2,自引:0,他引:2  
This paper was intended to examine how major life events – suchas retirement, deterioration of health, and loss of spouse –experienced in the aging process may affect the elderly's lifesatisfaction. An explanation was also proposed to the change inthe effects of age groups on life satisfaction because of thecontrol of the aging effect. A simple form of a longitudinalsurvey conducted in Taiwan in 1989 and 1993 was used for theempirical test. It was found that life satisfaction among theelderly decreased as age increased beyond 65 years of age. Itwas also found that social demographic variables, an incomedecrease, living arrangement, and level of activity participationhave a profound impact on life satisfaction of Taiwan's elderly. When the correlates were controlled, the coefficients for agegroups greater than 70 turned positive. This change could beexplained by two types of cohort experience: (1) from rough toprosperous life experience and (2) cohort norm on lifeexpectancy.  相似文献

The study assesses the pattern of disparities in socio-economic development at the district level in India applying the Wroclow Taxonomic technique (following Ewusi. Social Indicators Research 3(1) 75–110, 1976, and Arief. Social Indicators Research 11(3) 259–267, 1982) based upon optimal combination of selected socio-economic development indicators. In order to get a clear picture of regional socio-economic disparities in India, the level of development is assessed separately for agriculture, industrial and infrastructural sectors and the districts are classified into four development categories according to the values of the constructed development index. For bringing about uniform regional development and improving the quality-of-life, model districts for disadvantaged districts have been identified and potential targets for various social amenities have been estimated. An attempt has also been made to compare the levels of socio-economic development among various regions in India. The constructed socio-economic development index shows that India’s Southern region is far more and symmetrically developed in comparison of Central and Northern regions. The results show that wide disparities in the level of socio-economic development exist among different districts within and between different regions of India. The level of development in infrastructural service sector is found to be positively and statistically significantly associated with the overall socio-economic development indicating that the growth and progress of the sectors have been going hand in hand in the country. The results show that in Northern and Central regions of India the level of industrial development does not significantly influence the agricultural and overall socio-economic development while agricultural development influences overall socio-economic development. The study suggests that low developed districts require improvement in most of the indicators for enhancing their levels of overall socio-economic development.  相似文献

Following previous work on inequality in health opportunity, this paper attempts to determine the contribution of circumstances, efforts and lifestyle, and demographic variables to the overall inequality in health in Luxembourg. Health is measured via the answers given to a question on self-assessed health and is considered as an ordinal variable. The educational level of each parent, the financial situation of the family during childhood, the area of birth of the individual, and of his/her parents, and the year of immigration are considered as circumstances. Effort and lifestyle variables are proxied by information on the educational level of the individual, whether he/she smoked and whether he/she had a physical activity on a regular basis. Sex and age are considered as demographic variables. To solve the issue of correlation between circumstances and effort and lifestyle the estimation is implemented in two stages. In the first stage, each effort and lifestyle variable is regressed in a separate equation against the vector of circumstances and demographic variables and, in a second stage, the individual health status is regressed against the vector of circumstances and demographic variables along with the estimated residuals of the effort equations described previously. The respective impacts of the three categories of explanatory variables (circumstances, effort and lifestyle and demographic variables) on health inequality are derived via a Shapley decomposition of the likelihood ratio of the health ordered logit regression. It appears that differences in circumstances and effort and lifestyle explain each around a quarter of this likelihood ratio.  相似文献

Abstract

Narrative walking practices, or modes of conversational activity set in motion by the conditions of wayfinding, potentially offer mobile and dialogic methods of engaging with experiences of mobility and of representing those experiences. They also offer alternative ways of intervening in politics and policy impacting on the distribution of mobility or immobility. The artwork way from home employed such practices as a performative, participatory and interventional methodology for eliciting and representing the transnational experiences, affects and significances of place for refugees and asylum seekers across the UK. The various strategies conceived here as homing devices, homing tales and conversive wayfinding, were employed to construct ‘meeting places’ where transnational views, perspectives, experiences and knowledge could be exchanged. This methodology proposes alternatives to hegemonies of communication, representation and authorship in both artistic and scholarly production, through processes that interrelate experiential, analytical and interventional ways of knowing.  相似文献

Objective: To investigate thecorrelations between age- and gender-specificmeasures of socio-economic status versus healthstatus as measured by the SF-36. Design: Population based study. Participants: 38187 people aged between18 to 79 years who participated in the NationalHealth Survey in 1995. Results: Factor analysis producedconsistent results that were interpreted interms of five conceptually meaningful domains(employment, housing, migration, family unitand education). The relative rank of thefactors differs between groups and in somecases factor composition requires items to beadded or deleted from the conceptual domains. Conclusions: Age- and gender-specific SESscores based on these factors had strongerassociations with the physical and mentalcomponents of SF-36 than either an area basedindex or scores derived from males aged 40–44years. Overall the results supported thehypothesis that SES measures composed of socialand demographic items exhibit important age-and gender-specific differences which arerelevant for health.  相似文献

Methane (CH4) is one of the trace gases in the atmosphere that is considered to play a major role in what is called the greenhouse effect. There are six major sources of atmospheric methane: emission from anaerobic decomposition in (1) natural wetlands; (2) paddy rice fields; (3) emission from livestock production systems (including intrinsic fermentation and animal waste); (4) biomass burning (including forest fires, charcoal combustion, and firewood burning); (5) anaerobic decomposition of organic waste in landfills; and (6) fossil methane emission during the exploration and transport of fossil fuels. Obviously, human activities play a major role in increasing methane emissions from most of these sources. Especially the worldwide expansion of paddy rice cultivation, livestock production and fossil fuel exploration have increased the methane concentration in the atmosphere. Several data sets help estimate atmospheric methane concentration up to 160,000 years back. Major sources and sinks of present-day methane emission and their relative contribution to the global methane balance demonstrate great uncertainties in the identification and quantification of individual sources and sinks. Most recent methane projections of the Intergovernmental Panel on Climate Change (IPCC) for 2025 and 2100 are discussed and used to estimate the contribution of population growth to future methane emission. Finally the paper discusses options and restrictions of reducing anthropogenic methane emissions to the atmosphere.  相似文献

Subjective Well-being Among Young People in Transition to Adulthood   总被引:1,自引:0,他引:1  
This study used a nationally representative sample of young people in Germany from the German Socio-Economic Panel to examine how demographic and socio-economic characteristics of the young persons and their parents, personality traits of the young persons, quality and quantity of relationships, the parent's level of life satisfaction, and other measures of satisfaction for the young person are related to the initial assessment of life satisfaction by the individual at the critical point of transition from adolescence to adulthood. The results indicated that consistency existed across different domains of satisfaction, specifically satisfaction with life and satisfaction with grades. A strong pattern of association was also observed between the subjective well-being of the adolescents and variables that measured different dimensions of the quality and quantity of interpersonal relationships, including relationships with parents.

This paper reports on part of a study of “Reproductive facts, norms and attitudes among the various socio-economic groups of the white population in Johannesburg”, and deals with the incidence of fecundity and various degrees of sterility among a representative sample of white married couples under 50 years of age. The nature and incidence of fecundity is correlated with certain demographic and social variables such as age and duration of marriage, the use of contraception, fcetal deaths and childlessness, birth parity, income, occupation, home language, religion and occupational status.  相似文献

The temporal fluctuation of water levels and the presence of mosquito larvae were investigated for four types of small container habitats (treeholes, bamboo stumps, cemetery stone vases, and cemetery stone vessels) on Kabeshima Island in Kyushu, southwestern Japan. The probability that containers held water was positively correlated with the quantity of the preceding rainfall and with the depth and volume of the containers. It was estimated that dehydration occurred more regularly in autumn and winter than in summer. The probability that mosquito larvae were present in each type of container was positively correlated with habitat stability in terms of the probability of the existence of standing water and the coefficient of variation of the water level. Twelve species of mosquito larvae, including two rare predators, were found. Species composition differed between the different types of container. Although 4 to 10 species used each type of container, the median number of species per container was two for treeholes and bamboo stumps, and one for the others. The dominant species wasTripteroides bambusa in treeholes and bamboo stumps,Aedes albopictus in stone vases, andA. japonicus in stone vessels. The larval mosquito community, which lacked major predators, possessed the following features that may facilitate the coexistence of many species: (1) niche segregation amongst species in terms of their selection of container types; (2) an aggregated distribution of the individual species among containers of the same type; (3) high intraspecific mean crowding (and hence probably intense intraspecific competition) in the dominant species in each type of container; (4) independent species associations within the same type of container; and (5) low interspecific mean crowding (and hence probablynot intense interspecific competition) between species in the same type of container.  相似文献

This article explores new methods for gathering and analyzing spatially rich demographic data using mobile phones. It describes a pilot study (the Human Mobility Project) in which volunteers around the world were successfully recruited to share GPS and cellular tower information on their trajectories and respond to dynamic, location-based surveys using an open-source Android application. The pilot study illustrates the great potential of mobile phone methodology for moving spatial measures beyond residential census units and investigating a range of important social phenomena, including the heterogeneity of activity spaces, the dynamic nature of spatial segregation, and the contextual dependence of subjective well-being.  相似文献

The Early Development Instrument (EDI; Janus and Offord in Canadian Journal of Behavioural Science 39:1–22, 2007) project is a Canadian population-level, longitudinal research project, in which teacher ratings of Kindergarten children’s early development and wellbeing are linked to health and academic achievement variables at the individual level, and to demographic, cultural, and socioeconomic variables at the community level. In this article, we draw from Bronfenbrenner’s bioecological theory of human development to create a coherent theoretical framework for guiding validation research within a population-level approach to child development research in general and for the EDI project in particular. The discussion draws from a range of social and health sciences as well as validity theory. The paper seeks to align complex conceptual, theoretical, methodological, and psychometric considerations, to provide specific design, methodology, and validation recommendations for a population-level approach to studying children’s development and wellbeing, and to discuss the strengths and challenges of this approach.  相似文献

基于2017年全国流动人口动态监测调查数据和相关统计年鉴数据,使用嵌套Logit模型,以地级行政区为基本地域单位,以流量流动人口为研究对象,讨论流动人口的流入地选择机制问题。分析结果表明:流动人口中的流量样本与存量样本存在显著的结构性差异,且部分相同变量对两者具有不同作用;流动者个体所能切身感受到的社会经济回报在流入地选择机制中起重要作用;地级特征变量和个体特征变量的交互作用表明地区层级特征对流入地选择机制有异质性影响。结论认为,研究流动人口的不同问题时先要考虑使用流量样本还是存量样本;社会经济"预期回报"而非纯粹的"预期收入"是吸引流动人口的重要因素;流入地选择是流动者基于个体特征、结合流入地特征而做出的综合性的理性决策。  相似文献

Summary Interrelations among acarine, fungal, and environmental components of bulk grain ecosystems were determined by canonical correlation analyses. Twenty-seven variables were measured monthly in samples collected from 2 identical grain bulks in a granary in Winnipeg during the years 1959–67. The relationships between 9 kinds of arthropods and 6 environ mental variables, and between the same arthropods and 12 kinds of actinomycetes and fungi were examined. The maximum canonical correlation between arthropods and environmental factors was 0.35, and between arthropods and microorganisms was 0.28; both are highly significant (p<0.001). In the first analysis correlations of the variables with the canonical variates revealed that correlations of the variables with the canonical variates revealed that sampling location, depth, and temperature are the primary environmental antecedents involved, and the criterion is primarily composed of mitesTarsonemus spp.,Tydeus interruptus and the psocid,Lepinotus reticulatus. In the second analysis the fungiNigrospora sphaerica, Aspergillus spp., andCochliobolus sativus are involved with the mitesCheyletus eruditus andAcarus siro. Generally, the results of these analyses complement the findings of factor and regression analyses of the same data reported earlier.

The purpose of this paper is to suggest an improved measure of financial poverty, based on household consumption and wealth as well as income. Data come from the Household, Income and Labour Dynamics Australia (HILDA) Survey, which appears to be the first national socio-economic panel survey to provide longitudinal data on all three measures of household economic well-being. National measures of poverty in Australia and other Western countries are usually based only on low income. But this is conceptually incorrect; the measures lack validity. To be poor is to have a low material standard of living—involuntarily. So measures of poverty should also take account of household consumption and wealth. If a household has an adequate current level of consumption, it should not be classified as poor right now, even if its current income is low. Similarly, if it has substantial wealth (net worth), it should not be viewed as poor because it could draw down on wealth to boost current consumption. The invalidity of income-based measures has long been recognised in principle (Ringen 1987, The possibility of politics. Oxford: Clarendon Press). In practical terms, the problem is to combine measures of wealth and income, and especially consumption, in the same survey. In the 2005 HILDA Survey a battery of household expenditure items was included which, benchmarked against the Australian Bureau of Statistics’ Household Expenditure Survey for 2003–04, appeared to provide valid measurement of 53.4% of total household expenditure. These well measured items correlated 0.76 with total expenditure and, in combination with standard demographic variables, accounted for 78.3% of the variance in the total. This paper uses 2005–06 HILDA data to construct revised measures of financial poverty. The value of these measures for public policy and research purposes is illustrated. In particular, the new measures give much lower estimates of poverty than income-based measures. They can also be used to predict which households are at risk of future poverty.

Reproductive success, copulation success, and mating success were measured for a population of male dragonflies,Orthetrum japonicum. Copulation success explained the greatest variation in reproductive success. The proportion of copulations followed by oviposition was positively correlated with the number of oviposited eggs per mating. Directional selection on four morphological characters was estimated. The effect of selection on correlated traits was comparable to that of direct selection. Directional selection varied between traits and between episodes in a single trait. The probability that the observed directional selection on the four morphological traits was expected under the condition of the selective neutrality of traits was not smaller than 5%.  相似文献
