Private military and security companies (PMSCs) are a fast‐growing global industry. While the rise of PMSCs and their activities have attracted much media coverage and growing scholarly attention, little is known about their sourcing of masses of military labour from the global South. This exploratory study examines the case of Fiji, whose thousands of ex/current disciplinary force personnel and unemployed men have been contracted by PMSCs to provide security work in Iraq and other high‐conflict areas. The article shows this to be an instance of unequal core‐periphery military labour trade, outlining its scale, processes and impacts on the migrants. It also illuminates how the migrants’ collective agency is demonstrated even under powerful structural constraints.  相似文献

The goal and system resource approaches represent alternative conceptions of organizational effectiveness. The goal approach views effectiveness in terms of internal organizational objectives and performance. Organization-environment relations are the focus of the system resource approach, though previous applications of this perspective have been limited to profit-making organizations. This paper reconceptualizes the system resource approach for use in public agencies and examines the flow of organizational resources as an indicator of effectiveness. Goal approach indicators are matched with system resource measures in examining the convergence and consistency of the two approaches. The convergence of effectiveness measures is examined by observing the correlations between themselves and four organizational decision making variables that had previously been shown to be associated with effectiveness. An examination of the data collected through interviews with representatives of 110 public agencies reveals some consistency but no convergence between the two approaches.  相似文献

Climate change may be considered a natural disaster evolving in slow motion on a global scale. Increasing storm intensities, shifting rainfall patterns, melting glaciers, rising sea levels, and other manifold alterations are being experienced around the world. Climate has never been constant in any location, but human‐induced changes associated with greenhouse gases and fossil fuel use are new and rapidly shifting conditions for rural communities and regions across the planet. Rural sociologists have long been carving out the contours of this topic through research on family well‐being, rural livelihoods, community, and the environment. Now climate change and subsequent policy responses present a new and fundamental source of social change. The purpose of this article is to assess lines of research and theory that consider and direct our understanding of the impacts of climate change, the ways it might be mitigated, and the coping strategies of rural people and communities that are both victims and perpetrators in the global realignment. As climate‐change impacts and policy responses begin to impinge on rural populations, the first line of resistance and participation will be the rural community. The distribution of rewards from climate‐change mitigation is broad and diffuse; the distribution of costs, compromised livelihoods, and community disruption often is focused.  相似文献

This study examined the adjustment needs and efforts of individuals with dementia after relocation to a residential care facility. This was a qualitative prospective study that involved in-depth face-to-face interviews with 16 individuals with dementia and their family caregivers at 2 and 6 months post-relocation. In their efforts to recreate a sense of home, individuals with dementia had to meet three major highly interrelated and overlapping categories of needs to settle in, fit in, and find meaning in this transition. The satisfactory fulfillment of these adjustment needs resulted in a sense of comfort, connection, and continuity associated with feeling at home. Participants’ efforts to place themselves in their new living environments created a simultaneous need to integrate relocation into their overall sense of self. The results support earlier research indicating that place making is a critical process in the overall psychosocial adjustment to old age. The findings inform supportive interventions to assist individuals with dementia to reconstruct home in a residential care environment.  相似文献

Data from the Harvard School of Public Health College Alcohol Study (1993) were used to describe weekly alcohol consumption and its associated problems among a representative national sample of college students. The median number of drinks consumed/week by all students, regardless of drinking status, was 1.5. When students were divided by drinking pattern, the median number of drinks/week was 0.7 for those who did not binge drink and 3.7 for those who did so infrequently. For frequent binge drinkers, the median was considerably higher: 14.5 drinks/week. Nationally, 1 in 5 five college students is a frequent binge drinker. Binge drinkers consumed 68% of all the alcohol that students reported drinking, and they accounted for the majority of alcohol-related problems. The data indicate that behavioral norms for alcohol consumption vary widely among students and across colleges. Therefore, it may not be possible to design an effective "one size fits all" approach to address college alcohol use.  相似文献

Given a connected edge-weighted graph G and a positive integer B, the degree-constrained minimum spanning tree problem (DCMST) consists in finding a minimum cost spanning tree of G such that the degree of each vertex in the tree is less than or equal to B. This problem, which has been extensively studied over the last few decades, has several practical applications, mainly in networks. However, some applications do not especially impose a subgraph as a solution. For this purpose, a more flexible so-called hierarchy structure has been proposed. Hierarchy, which can be seen as a generalization of trees, is defined as a homomorphism of a tree in a graph. In this paper, we discuss the degree-constrained minimum spanning hierarchy (DCMSH) problem which is NP-hard. An integer linear program (ILP) formulation of this new problem is given. Properties of the solution are analysed, which allows us to add valid inequalities to the ILP. To evaluate the difference of cost between trees and hierarchies, the exact solution of DCMST and z problems are compared. It appears that, in sparse random graphs, the average percentage of improvement of the cost varies from 20 to 36% when the maximal authorized degree of vertices B is equal to 2, and from 11 to 31% when B is equal to 3. The improvement increases as the graph size increases.  相似文献

Attunement theories of speech perception development suggest that native‐language exposure is one of the main factors shaping infants' phonemic discrimination capacity within the second half of their first year. Here, we focus on the role of acoustic–perceptual salience and language‐specific experience by assessing the discrimination of acoustically subtle Basque sibilant contrasts. We used the infant‐controlled version of the habituation procedure to assess discrimination in 6‐ to 7‐month and 11‐ to 12‐month‐old infants who varied in their amount of exposure to Basque and Spanish. We observed no significant variation in the infants' discrimination behavior as a function of their linguistic experience. Infants in both age‐groups exhibited poor discrimination, consistent with Basque adults finding these contrasts more difficult than some others. Our findings are in agreement with previous research showing that perceptual discrimination of subtle speech sound contrasts may follow a different developmental trajectory, where increased native‐language exposure seems to be a requisite.  相似文献

Language rhythm determines young infants' language discrimination abilities. However, it is unclear whether young bilingual infants exposed to rhythmically similar languages develop sensitivities to cross‐linguistic rhythm cues to discriminate their dual language input. To address this question, 3.5‐month‐old monolingual Basque, monolingual Spanish and bilingual Basque‐Spanish infants' language discrimination abilities (across low‐pass filtered speech samples of Basque and Spanish) have been tested using the visual habituation procedure. Although falling within the same rhythmic class, Basque and Spanish exhibit significant differences in their distributions of vocalic intervals (within‐rhythmic class variation). All infant groups in our study successfully discriminated between the languages, although each group exhibited a different pattern. Monolingual Spanish infants succeeded only when they heard Basque during habituation, suggesting that they were influenced by native language recognition. The bilingual and the Basque monolingual infants showed no such asymmetries and succeeded irrespective of the language of habituation. Additionally, bilingual infants exhibited longer looking times in the test phase as compared with monolinguals, reflecting that bilingual infants attend to their native languages differently than monolinguals. Overall, results suggest that bilingual infants are sensitive to within‐rhythm acoustic regularities of their native language(s) facilitating language discrimination and hence supporting early bilingual acquisition.  相似文献
