Arrivals of new immigrants and the secondary migration of other immigrants to the Los Angeles area are estimated to be as many as 180,000 each year in the 1980s. The Southern California Association of Governments found three-quarters of the immigrants were low-income minorities who are more likely to live in overcrowded enclaves and pay disproportionately high rents. Other data suggest that immigrants—many of them undocumented and Hispanic—are both victims of and contributors to the housing crisis.Although aggravated by immigration, Los Angeles' low-cost housing ills stem from broader national, social and economic trends: gentrification and other commercial conversion of low-cost housing, stagnating federal housing aid, and diminished tax and loan incentives. Skyrocketing costs have dropped the rate of home ownership well below the national average, forcing more people to rent. Condominium conversions, costly safety regulations, rent controls and successful no-growth movements also have contributed to Los Angeles' housing crisis.  相似文献

This paper reports the outcome of an exercise in curve fitting to annual sets of Danish age-specific fertility rates for the years 1962 to 1971 by means of least squares. Functions fitted were a cubic spline, the Hadwiger and Coale-Trussell functions, the gamma and beta densities, two versions of a polynomial, and two of Brass's relational procedures, as well as the Gompertz curve. The spline function fitted all curves far better than any of the others. The Coale-Trussell procedure and gamma density were about equal, followed by the Hadwiger function. All of these functions fit the data well. One of the polynomials fit reasonably well, but the rest of the functions were less accurate.  相似文献

This article examines relationships between strategic planning and consensus building with external groups and constituencies. Methods for consensus building with external groups during strategic planning and implementation are discussed and five cases from different economic and political sectors are examined in conjunction with the principles considered.  相似文献

While many studies of interventions have focused on their content and immediate effects, less research has focused on the processes that may explain these effects. The purpose of this study was to show how process evaluation can be used to interpret the results of an intervention study in four industrial canteens in Denmark. Two canteens acted as intervention groups and two as comparison groups. Effects were measured by surveys before and after interventions, and observations and interviews were conducted to provide an in-depth understanding of processes. Analyses were conducted based on the responses from 118 employees. Results showed, contrary to expectations, improvements in working conditions and well-being in one intervention group and in one comparison group, whereas no improvements were found in the two remaining groups. Data from the process evaluation enabled a meaningful interpretation of these results, raising the possibility programme failure rather than theory failure, and thereby constituting an example of how process evaluation can shed light over the factors that may influence outcomes in controlled intervention studies.  相似文献

A sample of 3,201 Danes was subjected to personal interviews in which they were asked to state their preferences for risk-reducing health care interventions based on information on absolute risk reduction (ARR) and relative risk reduction (RRR). The aim of the study was to measure the relative weighting of different types of risk information under various circumstances. The effect of presenting questions, and of explicitly formulating RRR, was analyzed. A preference for increases in RRR was demonstrated. There was a stronger inclination to choose the intervention that offered the highest RRR if RRR was explicitly stated. Individuals with more than 10 years of schooling also demonstrated a preference for increased ARR, but only when facing individually framed choices. In a social choice context, preferences for RRR remained intact, but the magnitude of ARR had no impact on choices. Results imply that social framing may induce a propensity to prefer interventions that target high-risk populations. Those respondents who had received < or = 10 years of schooling demonstrated preferences for RRR but not ARR, and no impact of social framing was observed.  相似文献

Building upon early work of E. A. Cornish we show that G. N. Wilkinson's version of Yates' approach to the analysis of designed experiments with a single error stratum carries over completely to designs with an arbitrary non-singular covariance matrix, initially assumed known. We show that the equations, corrections, adjustments and algorithms all have their more general analogues and that these can be solved, computed or executed quite readily if the design has orthogonal block structure and satisfies Nelder's condition of general balance. The results are illustrated with a split-plot and a simple (square) lattice design.  相似文献

Several demographic trends have changed family formation in the United States resulting in fewer babies being made available for adoption. At the same time the number of transracial adoptions appears to be increasing. We use the 5% Public Use Microdata Sample of the 2000 census and the National Survey of Adoptive Parents to examine the social and demographic characteristics of those who adopt transracially. Transracial adoption of Hispanic and Asian children, but not Black children, is associated with higher income and education levels. It is less likely in the South, but more likely among those who have had military experience.  相似文献

In “Something More”: The Meanings of Marriage for Religious Couples in America, Dollahite, Hawkins and Parr (2012) present a qualitative study that includes interviews with religiously observant married couples to investigate marriage. The current paper reviews the aforementioned study with respect to its trustworthiness, through dependability, credibility, confirmability and transferability, to encourage the elevation of qualitative work in our field. We discuss a number of challenges in the study design, methods, interpretation, and conclusions. In sum, our reading of the study left us wanting “something more” scholarly rigorous for the field of marriage research and qualitative work.  相似文献

The impact of transformational leaders on employee health and well-being has received much attention. Less research has focused on the relationships between transformational leaders and followers’ sickness absenteeism. Transformational leaders promote a group climate that may lead to absenteeism, especially among vulnerable employees (those with high levels of presenteeism). In the present study we examined the relationships between presenteeism, group-level transformational leadership and sickness absence rates in a three-year longitudinal study of postal workers and their leaders in Denmark (N?=?155). Group-level transformational leadership in year 1 predicted sickness absenteeism in year 2, but not in year 3. In examining conditions under which transformational leadership may be linked to higher levels of sickness absenteeism, we found that presenteeism in year 1 moderated the link between transformational leadership in year 1 and sickness absenteeism in year 3, such that followers working in groups with a transformational leader and who were high in presenteeism reported higher levels of sickness absenteeism. Our results suggest a complex picture of the relationship between transformational leadership and sickness absenteeism; transformational leaders may promote self-sacrifice of vulnerable followers by leading them to go to work while ill, leading to increased risks of sickness absence in the long term.  相似文献
