This paper examines the concern for relative standing among rural households in China. We used a survey-experimental method to measure to what extent poor Chinese farmers care about their relative income. We found compared to previous studies in developed countries, the concern for relative standing seems to be equally strong among rural households in China. This should be seen in the light of the rapid change China has undergone, with high growth, and increased inequality. Thus, the rural population, which is lagging behind, is suffering not only from the low absolute income but also from low relative income. 相似文献

ABSTRACT This article describes the development and empirical status of guided Internet-delivered self-help. The treatment approach combines the benefits of bibliotherapy with book-length text materials and the support given online via web pages and e-mail. Interactive features such as online registrations, tests, and online discussion forums are also included. Cognitive behavior therapy (CBT) guided the research and clinical implementations of this approach, as it lends itself more easily to the self-help format compared with other presently available psychotherapy approaches. We include an overview of the research, current issues and research in service delivery, lessons learned through a program of research, and directions for future investigations. 相似文献

A mechanistic model and associated procedures are proposed for cancer risk assessment of genotoxic chemicals. As previously shown for ionizing radiation, a linear multiplicative model was found to be compatible with published experimental data for ethylene oxide, acrylamide, and butadiene. The validity of this model was anticipated in view of the multiplicative interaction of mutation with inherited and acquired growth-promoting conditions. Concurrent analysis led to rejection of an additive model (i.e. the model commonly applied for cancer risk assessment). A reanalysis of data for radiogenic cancer in mouse, dog and man shows that the relative risk coefficient is approximately the same (0.4 to 0.5 percent per rad) for tumours induced in the three species.Doses in vivo, defined as the time-integrated concentrations of ultimate mutagens, expressed in millimol × kg–1 × h (mMh) are, like radiation doses given in Gy or rad, proportional to frequencies of potentially mutagenic events. The radiation dose equivalents of chemical doses are, calculated by multiplying chemical doses (in mMh) with the relative genotoxic potencies (in rad × mMh–1) determined in vitro. In this way the relative cancer incidence increments in rats and mice exposed to ethylene oxide were shown to be about 0.4 percent per rad-equivalent, in agreement with the data for radiogenic cancer.Our analyses suggest that values of the relative risk coefficients for genotoxic chemicals are independent of species and that relative cancer risks determined in animal tests apply also to humans. If reliable animal test data are not available, cancer risks may be estimated by the relative potency. In both cases exposure dose/target dose relationships, the latter via macromolecule adducts, should be determined. 相似文献

Much of the considerable confusion about the definition of social entrepreneurship in academic literature stems from a lack of empirical research on the subject. This article advances social entrepreneurship research beyond conceptualization discussions by developing and validating an instrument that quantifies the incidence of nonprofit entrepreneurial behavior. Information from 145 Kansas City Metropolitan Area nonprofit organizations was collected to validate the underlying constructs represented in the instrument. Behavior differences were depicted between entrepreneurial and nonentrepreneurial nonprofits. Using principal component factor analysis, the research illustrates social entrepreneurship as a unique nonprofit behavior that occurs at the intersection of innovation, proactiveness, and risk taking. 相似文献

Since the 2004 EU enlargement established one European common labour market, a large number of Eastern Europeans have taken up seasonal employment as hired farm workers in Norwegian agriculture. Much attention in the public has been given to the potential for ‘social dumping’ of these migrating workers, as they are considered prone to exploitation by farmers looking for cheap and docile labour, and subject to low-wages and poor labour conditions. In response to these threats, Norway implemented labour regulations (‘transitional rules’) that established minimum standards for wage levels and labour conditions, combined with registration and supervision of the incoming labour force. Nevertheless, reports from the field indicate that many of the westward migrating labour force experience work conditions that are far poorer than prescribed by the labour regulations, as these are not implemented at the farm level. In this paper, we discuss the social processes that result in this mismatch between state regulations (e.g. transition rules) and the actual experiences of migrant workers building on dual labour market theory. Analysing qualitative in-depth interviews with 54 farm migrants, we argue that there are two sets of factors underlying the poorer working conditions observed on the farms: Firstly, the structural disempowerment of migrant workers, which gives them weak negotiating positions vis-à-vis their employers (farmers); and secondly, the migrant workers' frame of reference for wage levels, in which poor payment levels by Norwegian standards are found acceptable or even good when judged by Eastern European wage levels. While a number of works have described the exploitation of farm migrant labour, we demonstrate in this paper how national immigration and agricultural histories, structures and present policies configure the labour–capital relations at farm level in the Norwegian case. 相似文献

Abstract. During the 1990s, a new subsidized early retirement option was assigned quasi‐randomly to two‐thirds of Norwegian elderly workers. We use this ‘natural experiment’ to evaluate how economic incentives affect retirement behaviour. The new retirement option reduced employment substantially, and this effect escalated over time. It did not substitute for disability pension or long‐term unemployment, and approximately two out of three retirees would have stayed employed without it. Subsidized retirement was primarily voluntary, but there is also some evidence that firms took advantage of the retirement programme to ‘push out’ excess workers. 相似文献

Pierre Bourdieu argued for the existence of general properties and even laws of social fields. In contrast to spaces of class relations and patterns of cultural lifestyles, however, almost no systematic comparative research exists on the homologies of national social fields of a more specialised nature. Also, the large majority of research is done on Western countries, raising concerns about the relevance of the concept for less differentiated societies. Using the field of journalism as a case, typical structures of 67 national fields (n = 27,567) are in this article investigated using a reverse approach: First, the subjective spaces of journalists' experienced constraints and imperatives in their jobs are sketched as a proxy for field structure using variants of multiple correspondence analysis, and second, the distribution of the social and professional properties of journalists are used to suggest capital structures. The results suggest great stability in the fundamental organising principles of fields of journalism around the world, although with considerable variation in their autonomy. 相似文献

European economies display large variations in unemployment rates across regions as well as between education groups. Insufficient labour mobility is widely believed to contribute to higher regional disparities and overall unemployment, but few studies have compared mobility responses of different education groups to regional shocks. This paper employs administrative registers covering the entire Norwegian population to compute annual time series from 1994 to 2004 of migration flows and regional labour market conditions by education level for 90 travel‐to‐work areas. We find that regional disparities in unemployment rates are decreasing in education level, whereas the response of migration flows to regional unemployment shocks is increasing in education level. The results suggest that low regional mobility of low‐educated workers may contribute to higher regional disparities and higher overall unemployment among the low educated. 相似文献
