Ethnic minorities in England and Wales are spatially concentrated in relatively-deprived urban areas. Both geographic clustering and the economic characteristics of ethnically-concentrated neighbourhoods can impact upon the opportunities and constraints facing residents of such areas. This paper explores the relationship between the existence of enclaves and the employment prospects of ethnic minorities in England and Wales. It is shown that there is considerable spatial variation in employment outcomes. There is a lower incidence of self-employment in more ethnically-concentrated urban areas, which contradicts the view of ethnic entrepreneurship as an enclave phenomenon. Unemployment rates are also higher for minorities living in more concentrated areas. Enclaves in England and Wales do not appear to offer many economic benefits to minority individuals.

Who do farmers trust? Irrigators in the High Plains are confronted with a wide range of information sources with respect to water-saving practices. From a survey of 709 irrigators in 10 countries the most widely accepted sources are identified, regional variability of information is examined, the role of irrigator characteristics on source selection is determined, and the level of association between adoption and source preference is analyzed. Differences in irrigators' reliance on specific sources are more associated with location than irrigator characteristics. Information sources viewed as important by many irrigators frequently influence adoption decisions less than sources having a wide range of preference among irrigators. Mass media and advisor-oriented sources are much more significantly linked to adoption than inter-personal sources such as friends and neighbors. The three sources that best discriminate adoption behavior are private agricultural consulting firms, university research stations, and trade magazines.  相似文献

The emphasis in class research remains on the structural aspects of class, class processes are neglected. This paper focuses upon some relational and normative aspects of class through an examination of social divisions produced and constructed within middle class families’ choices of childcare. Working with data from two contrasting settings in London (Battersea and Stoke Newington) three issues are addressed in the paper; the extent to which childcare arrangements both substantively and structurally position children differently within long term educational careers; the ways in which the use of choice in a market system of child care and education, works to produce patterns of social closure that quietly discriminate via the collectivist criterion of class and racial membership; and the ways in which child care choices also point‐up and perpetuate subtle distinctions and tensions of values and lifestyle within the middle class, between class factions. Concepts drawn from the work of Bourdieu are deployed throughout.  相似文献

Issue Framing and Citizen Apathy Toward Local Environmental Contamination   总被引:1,自引:0,他引:1  
We adapt the frame-alignment perspective in order to demonstrate how institutional framing shapes media coverage of a toxic crisis. This framing activity is described as a new approach to managing public responses to contamination that differs from the approach characterizing contamination episodes at Love Canal and Woburn, MA. Our analysis focuses on the process by which actors responsible for managing toxic crises carefully construct and manage a coordinated risk frame. We refer to this as institutional framing and illustrate how it shapes media framing of a toxic event. We conclude by proposing further research to identify the causal relationship between institutional framing and the absence of mobilization.  相似文献

This study investigated child welfare practitioners’ ratings of the severity of parental discipline practices. Ratings varied by the type of act, age of the child, and by chronicity. Exploratory investigation into changes across time found that current practitioners (N = 27) rated several practices (e.g. spanking and shaking) as more severe than did professionals (N = 24) sampled in 1977. Results underscore the complexity of defining child maltreatment and offer implications for practitioners, applied researchers, and child welfare policy makers.The authors Stephen D.

Let G be a connected graph with n≥2 vertices. Suppose that a fire breaks out at a vertex v of G. A firefighter starts to protect vertices. At each time interval, the firefighter protects one vertex not yet on fire. At the end of each time interval, the fire spreads to all the unprotected vertices that have a neighbor on fire. Let sn(v) denote the maximum number of vertices in G that the firefighter can save when a fire breaks out at vertex v. The surviving rate ρ(G) of G is defined to be ∑ vV(G)sn(v)/n 2, which is the average proportion of saved vertices. In this paper, we show that if G is a planar graph with n≥2 vertices and having girth at least 7, then $\rho(G)>\frac{1}{301}$ .  相似文献

This paper presents a theoretical model to help managers visualise and manage confidential situations more effectively. The model metaphorically likens a confidential setting to the properties of a soap bubble, e.g. elastic expansion or contraction, minimal surface area to contain a given volume, fragility, surface tension, pressure, stress, strain and the potential for bursting thereby releasing the contents to the external environment. We explore the conceptual developments in two phases. Firstly, looking at how a bubble and confidential scenario form and grow. Secondly, we consider how a bubble may burst and map these forces to ways in which confidentiality may be breached. Many attributes are mapped, the key ones being: the embedded value within the system, the criticality of maintaining confidentiality, increasing pressure, the corresponding stress/strain dynamics and the levels of trust between stakeholders. Key research propositions are derived from the model which aims to minimise the risk of a confidentiality breach.  相似文献
