The Regional Concentration of China's Interprovincial Migration Flows, 1982–90

Internal migration has become an increasingly significant element in the redistribution of population and in the planning of socio-economic development in China. Based on the 1987 survey, the 1990 census, and additional data from the 1995 survey, this paper investigates the regional concentration of China's interprovincial migration flows and the gender differential in such concentration. The analysis was undertaken using the coefficient of variation (CV) indices of out- and in-migration flows for each province. The CV indices confirm that each province has its own migration flow field, and the differences lie mainly in the degree of the regional concentration. The asymmetry between out- and in-migration flow fields suggests that China's interprovincial migration has resulted from an interplay of several factors, such as the uneven distribution of the economy, inflow of trans-national capital into pockets of its provinces, and relaxed control over rural-to-urban migration. Findings also illustrate that a select number of provinces play an important role in redistributing migrants in China, specifically, in provinces such as Guangdong, Guangxi, Sichuan and Hunan. Investigation of the gender differential in the CV indices reveals that female migration flows are more regionally concentrated than male migration flows. This finding is significant in understanding migration constraints for Chinese women.     

The Time-Pressure Illusion: Discretionary Time vs. Free Time

People’s welfare is a function of both time and money. People can – and, it is said, increasingly do – suffer time-poverty as well as money-poverty. It is undeniably true that people feel increasingly time pressured, particularly in dual-earner households. But much of the time devoted to paid and unpaid tasks is over and above that which is strictly necessary. In that sense, much of the time pressure that people feel is discretionary and of their own making. Using data from the 1992 Australian Time Use Survey, this paper demonstrates that the magnitude of this ‘time-pressure illusion’ varies across population groups, being least among lone parents and greatest among the childless and two-earner couples.     

The Wealth of Nations and the Happiness of Nations: Why “Accounting” Matters

We review income-happiness research in light of competing theoretical frameworks, unit of analysis, and methodological issues. Within-countries, absolute income is weakly related to happiness, comparison effects depend on the measure utilized, and income change and perceived income produce inconsistent findings. Across countries, absolute income is a stronger predictor of happiness, different comparison effects are significant, income change results are predominantly positive, and the financial-life satisfaction relationship is more robust.     

Income and “Outcomes” for Elderly: DO the Poor have A Poorer Life?

The objective of this paper is to analyze the relationship between income and living conditions and well-being of elderly. The best from two worlds is used for this purpose: a Danish survey covering 1440 elderly aged 72 and 77 from 1997, connected to reliable register information on income, 1988–1996. Indicators of physical activity, social and solitary activities, social contact, functional capability, loneliness and psychological well-being are constructed from the survey. Ordered logistic models are estimated controlling for demographics, education, previous occupation and whether the elderly are still working. It is found that elderly with low income levels have poorer functional capability, lower physical activity and poorer psychological well-being whereas social contact and social activities show no relationship with income. The relationship with income vanishes for solitary activities and loneliness when adding control variables. Having established that robust relations exist between income and some measures of well-being of elderly, we turn to an investigation of causality. Simultaneous models are estimated to assess whether the income relationship can be causally interpreted for functional capability and physical activity. The results show that it cannot be rejected that the income effects are causal, although care should be taken when interpreting results. We finally address our findings in the light of current and future changes regarding the size and economic well-being of the elderly population.     

Self-Efficacy,Pulmonary Function,Perceived Health and Global Quality of Life of Cystic Fibrosis Patients

This study examined the extent that pulmonary function is related to perceived health status and global quality of life in adults suffering from cystic fibrosis, and the extent that self-efficacy modifies these relationships. Our sample comprised 86 adults (48% female; mean age, 29 years; age range, 18–54 years) with cystic fibrosis, recruited from the Norwegian Competence Centre for Cystic Fibrosis (83% response rate). Both subjective data on psychosocial aspects of living with cystic fibrosis, and objective data on pulmonary function (FEV1%) were assessed. Psychosocial aspects were assessed by a questionnaire that included St George’s Respiratory Questionnaire (perceived health status), the Generalized Self-Efficacy Scale (perceived self-efficacy), and the Quality of Life Scale (global quality of life). We found that self-efficacy is an additional factor explaining health status and global quality of life. Pulmonary function is important for health status, but not for global quality of life, for which perceived self-efficacy and health status are the most significant variables. These results show that self-efficacy is as important as pulmonary function for the perceived health status and global quality of life of patients. These valuable findings should be considered in the treatment and care of adult patients suffering from cystic fibrosis.     

Stability of environment and of insect populations

Summary The abundance of moths was monitored with light-traps in two sites in southern Bohemia, České Budějovice for 22 years and in Černiš for 9 years. In these sites, that are vastly different in environmental stability and predictability, stability of insect populations was studied. The amplitude of fluctuations in abundance of the insect populations, as measured by the coefficient of variation (CV), varied a great deal between species so that there was a large overlap between the two sites. Nevertheless there was a highly significant tendency for species at Černiš, the more stable site, to have smaller values of CV, i.e., to be less fluctuating. Also in species co-occurring in the two sites, the CV at Černiš tended to be smaller. Trends in abundance of individual species over time, both increases and decreases, were common in both sites and did not differ between habitats. Environmental stability begets insect population stability in terms of the amplitude of the fluctuations, but trends in time occur irrespective of stability of the habitat.     

改革开放后北京、上海、广州对流动人口的经济拉力因素的分析

本文以推拉理论建立多元线性模型并运用逐步回归的方法,分析改革开放后北京、上海、广州吸引流动人口流入的经济因素。结果显示流动人口主要依据微观经济因素做出流动迁移决策;不同城市对流动人口产生拉力的具体的微观经济因素不尽相同,即使有相同经济拉力因素的城市,拉力的大小也有差异;三城市的流动人口就业的分布不同,广州流动人口就业集中分布于第三产业,北京和上海则不然。     

Metabolism and Driving Forces of Chinese Urban Household Consumption

This study was aimed at developing a better understanding of environmental pressure of urban household consumption in China. First, we introduced the concept model of household metabolism. Using this model, we analyzed the changes of Chinese household metabolism during the last 20 years. Rather than taking into account all aspects of household consumption, we just focused on water and energy metabolisms. After exploring the clearly increasing trends of urban household metabolism in China, we identified the underlying driving forces as biological/physical factors, economic/marketing factors and demographic factors. In conclusion, we suggest that additional work must be carried out in a wider range of household activities and at more advanced research levels in China.
