ABSTRACT

Transnational mobilities are often conceived as interconnected with cities as ‘magnets’ for migrants, ‘nodes’ in mobility trajectories or ‘destinations’ for settlement. This paper frames the urban as critical to conceptualising the manner that mobility is actively and contingently assembled across the border and in the constitution of migrant lives. This argument builds on understanding the relationship between urban life and migration regimes in South Korea where the state and infrastructures of migration play a strong role in moulding the forms and outcomes of transnational mobilities in the everyday spaces of cities. The paper examines the urban lives of two differently positioned mobile populations in the Seoul Metropolitan Region: migrant workers in the manufacturing industries and English teachers working in schools, private academies and universities. Drawing on Said’s ‘contrapuntal’ analysis, the paper explores the ways in which these migrant lives overlap and diverge: in recent political-economic transformations and the regulation of migration, the urban geographies of labour and life, and the timing of migration. In doing so, the paper offers a window into Seoul’s emerging reliance on and differential incorporation of migrants and demonstrates the critical interlinkages between the governmental technologies of border crossing, everyday life and possibilities for the future.  相似文献

This study examines two issues. First, we assess the reliability of employment data self‐generated by respondents using a survey panel of 280 firms surveyed in 1999 and again in 2002. Our results show that there is a close correlation between self‐generated and archival secondary data. Second, we test for bias in the recall of previous years' employment levels and the sources of such bias. We assess three reasons for recall bias: respondent‐level factors; firm‐level factors; and anchoring. Our regression results indicate that: owners and new respondents; those in firms that changed legal status and/or location; those in smaller firms; and those in growing or declining firms were biased in their recall of prior employment. In addition, growing firms tended to underestimate their growth, which points to anchoring as an explanation for these biases. These biases imply that we have to be careful in delineating performance measures and cautious about how we interpret self‐generated managerial information.  相似文献

This study presents statistical techniques to obtain local approximate query answers for aggregate multivariate materialized views thus eliminating the need for repetitive scanning of the source data. In widely distributed management information systems, detailed data do not necessarily reside in the same physical location as the decision-maker; thus, requiring scanning of the source data as needed by the query demand. Decision-making, business intelligence and data analysis could involve multiple data sources, data diversity, aggregates and large amounts of data. Management often confronts delays in information acquisition from remote sites. Management decisions usually involve analyses that require the most precise summary data available. These summaries are readily available from data warehouses and can be used to estimate or approximate data in exchange for a quicker response. An approach to supporting aggregate materialized view management is proposed that reconstructs data sets locally using posterior parameter estimates based on sufficient statistics in a log-linear model with a multinomial likelihood.  相似文献

When strategic plans go awry and begin losing money, the smart thing to do is change course. But some leaders get so involved with the plan, they fail to navigate properly and fly right into the target. The organization can lose millions. Examine why this happens and what you can do to prevent it from happening in your organization.  相似文献

A self‐regulated epidemic model was developed to describe the dynamics of Salmonella Typhimurium in pig farms and predict the prevalence of different risk groups at slaughter age. The model was focused at the compartment level of the pig farms and it included two syndromes, a high and a low propagation syndrome. These two syndromes generated two different classes of pigs, the High Infectious and the Low Infectious, respectively, which have different shedding patterns. Given the two different classes and syndromes, the Infectious Equivalent concept was used, which reflected the combination of High and Low Infectious pigs needed for the high propagation syndrome to be triggered. Using the above information a new algorithm was developed that decides, depending on the Infectious Equivalent, which of the two syndromes should be triggered. Results showed that the transmission rate of S. Typhimurium for the low propagation syndrome is around 0.115, pigs in Low Infectious class contribute to the transmission of the infection by 0.61–0.80 of pigs in High Infectious class and that the Infectious Equivalent should be above 10–14% of the population in order for the high propagation syndrome to be triggered. This self‐regulated dynamic model can predict the prevalence of the classes and the risk groups of pigs at slaughter age for different starting conditions of infection.  相似文献

By what mechanisms has China's developing capitalist labor market been producing stratification patterns of reemployment and wage differences among laid‐off workers in the late 1990s? Theoretical perspectives delineating state, market, and societal mechanisms are used to guide exploratory analyses of data from a sample of workers who were laid off from state‐owned textile enterprises in the Tianjin municipality. Three findings are reported. First, men with what Portes defined as downward leveling “negative social capital” are less likely to become reemployed. A second, more tenuous, finding is that workers with a higher level of education are more likely to be reemployed. Third, workers with a social network tie to at least one official from a government administrative agency are more likely to be reemployed and, among those reemployed, more likely to earn higher wages, as compared to workers with a social network tie to at least one official from a state‐owned enterprise or workers lacking a social network tie to any official. This third finding, along with reports of analogous findings culled from a review of published literature, stimulates us to go beyond the data to theoretically speculate about how Chinese officialdom has become somewhat more differentiated and consequent ramifications for understanding newly emerging changes in China's stratification order.  相似文献

Individual, household and gender preferences for social transfers   总被引:1,自引:0,他引:1  
This paper reports the results of a nationally representative survey that explored willingness to pay extra taxes for increased levels of social transfers in Ireland. Respondents differ in their interpretation of willingness-to-pay questions with respect to the relevant income constraint being the individual’s budget or the individual’s household budget, with an important explanatory variable in this interpretation being the level of financial management integration within the household. Respondents are also shown to take intra-household bargaining considerations into account when stating preferences for specific redistributive policies; a significant gender difference emerges for a specific fiscal policy (child benefit) which alters the intra-household entitlement to income.  相似文献

This paper is an exploration of social work placements with students who are living with a disability. The paper discusses hurdles including censoring placements and opportunities, equal access, strategies for building a belief in ability and self-esteem. Field education is a significant part of the social work degree internationally. It allows social work students to further develop their social work identity and to apply their knowledge to professional practice through real-life learning. The paper broadens the conversation on social work placements and ability, adding some personal narratives and sharing some insights from an Australian university context.  相似文献

Abstract

“Ten years ago this country made putting a man on the moon by 1970 a national goal, and by 1970 an American astronaut landed on the moon. With the 1949 Housing Act, the Federal Government established a national goal of providing “a decent home, a suitable living environment for every American family,” but it made no commitment to that goal. Every day that we wait the problem of urban housing gets bigger, and every day it becomes more expensive to correct Let us turn our attention now from scientific achievement to the need for achievement of a different kind. For if one thing can be said of the housing problem, it is that it will be harder to solve than it was to put a man on the moon.” (Romney, Secretary, H.U.D., 7-21-69)  相似文献
