This article surveys recent developments in relation to the dimensions of ethnicity and ethnic disadvantage in social policy research and practice, with a focus on social care. While there has been limited increase in attention to ethnicity within general policy discussion and increasing sophistication within specialist debates, advances in theory and methodology have largely failed to penetrate the research mainstream, let alone policy or practice. This is a long‐standing problem. We advocate more focused consideration of ethnicity and ethnic disadvantage at all levels. Failure to do so creates the risk of social policy research being left behind in understanding rapid changes in ethnic minority demographics and patterns of migration, with increasing disadvantage to minorities.  相似文献

Abstract

An index of racial residential segregation for a city may be calculated from census data reporting the number of white and nonwhite households resident in each city block. Such an index summarizes the dissimilarity in residential location of the two groups. Segregation indexes for 109 cities for the years 1940, 1950, and 1960 were published in Taeuber and Taeuber Negroes in Cities (1965).

Segregation indexes for 109 cities for 1970, together with the previously published indexes for the three earlier census dates, are presented in Table 1. The trend data from 1940 through 1970 refer to residential segregation of whites and nonwhites. For 1970 only, segregation indexes are also presented comparing whites and Negroes.

The trend data reveal a distinctive pattern of change during each of the three decades. From 1960 to 1970, declines in segregation prevailed among cities in each region of the country.

The indexes for 1970 were calculated from Public Use Summary Tapes issued by the Bureau of the Census. Certain difficulties were encountered in the use of these tapes. A methodological appendix describes the data source and retrieval procedure for calculation of city segregation indexes for 1970.  相似文献

In this qualitative study, we explore how incumbent firms in traditional industries build dynamic capabilities for digital transformation. Digital transformation has been defined as the use of new digital technologies, such as mobile, artificial intelligence, cloud, blockchain, and the Internet of things (IoT) technologies, to enable major business improvements to augment customer experience, streamline operations, or create new business models. In making sense of digital transformation, we discovered that leaders in various industry circles use the term inconsistently to describe various strategizing and organizing activities; in addition, the term has gained limited scholarly attention as a context for study of strategic change. Drawing on senior executives' experiences with leading digitalization projects at incumbent firms, we propose a process model comprising of nine microfoundations to reveal the generic contingency factors that trigger, enable, and hinder the building of dynamic capabilities for digital transformation. Our findings reveal that digital transformation is an ongoing process of using new digital technologies in everyday organizational life, which recognizes agility as the core mechanism for the strategic renewal of an organization's (1) business model, (2) collaborative approach, and eventually the (3) culture.  相似文献

Using data from the Seattle Social Development Project, we identify childhood predictors of offending trajectories among poor children. Five trajectories are identified: nonoffenders, late onsetters, desisters, escalators, and chronic offenders. Among initial nonoffenders, late onsetters are distinguished from nonoffenders by early alcohol drinking. Among youths already delinquent at age 13, escalators are distinguished from desisters by poor family management, family conflict, association with antisocial peers, the presence of troubled children in their neighborhoods, and drug availability. In contrast to prior findings for a general urban sample, family factors significantly predict desistance from offending by age 18 in children from low-income families.  相似文献

This study compared men's and women's pathways to adulthood by examining how role transitions in education, work, marriage, and parenthood intersect and form developmental pathways from ages 18-30. The study investigated how sociodemographic factors and adolescent experiences were associated with these pathways. We used latent class analysis to analyze longitudinal data from a gender-balanced panel of 808 contemporary young adults. We found three similar latent pathways for both genders, but men and women differed in the timing of marriage and when they began to live with children and the likelihood of combining both roles. The present study points to the continued, though differential, relevance of marriage and family in the transition to adulthood for men and women.  相似文献

This article explores the development of a scheme to use Information and Communication Technology (ICT) in the training of individuals with severe functional impairments. Computers were used as an integral part of a rehabilitation programme for training, and the authors found that the resource was a useful addition to other treatment methods. This article describes the development and subsequent setting up of computers for training and how the study progressed. The study used a somewhat unique bottom up approach that first trained care-giving staff in computer skills. The caregivers in turn worked with and trained some of those they served. This learning strategy drew upon the concept of learning, empowerment and the motivation of all involved in a system and process. The study found that by using ICT all involved felt a greater sense of empowerment and improvement in the quality of life. That caregivers were involved at all stages was valuable in that they felt an ownership of the process and that they also benefited from being involved because they also learned new skills.  相似文献

A method is presented for applying the cause table concept to the problem of common cause events. This method can be regarded as an alternative to the approach in which these events are included directly into the system fault trees. In comparison with this approach, the cause table method offers the advantage of simple fault trees, convenient visibility of the contributions of causes, and the ability to truncate the numerical calculation conveniently by aggregating small terms into an "other" category. Generally speaking, the cause table method can be said to handle common causes at the level of arithmetic (i.e., numbers) rather than at the level of algebra (determining cutsets and frequency equations).  相似文献
