Capacity utilization measures have traditionally been constructed as indexes of actual, as compared to “potential,” output. This potential or capacity output (Y*) can be represented within an economic model of the firm as the tangency between the short- and long-run average cost curves. Economic theoretical measures of capacity utilization (CU) can then be characterized as Y/Y* where Y is the realized level of output. These quantity or primal CU measures allow for economic interpretation; they provide explicit inference as to how changes in exogenous variables affect CU. Additional information for analyzing deviations from capacity production can be obtained by assessing the “dual” cost of the gap.

In this article the definitions and representations of primal-output and dual-cost CU measures are formalized within a dynamic model of a monopolistic firm. As an illustration of this approach to characterizing CU measures, a model is estimated for the U.S. automobile industry, 1959–1980, and primal and dual CU indexes are constructed. Application of these indexes to adjustment-of-productivity measures for “disequilibrium” is then carried out, using the dual-cost measure.  相似文献

Statistical procedures for the detection of a change in the dependence structure of a series of multivariate observations are studied in this work. The test statistics that are proposed are $L_1$ , $L_2$ , and $L_{\infty }$ distances computed from vectors of differences of Kendall's tau; two multivariate extensions of Kendall's measure of association are used. Since the distributions of these statistics under the null hypothesis of no change depend on the unknown underlying copula of the vectors, a procedure based on the multiplier central limit theorem is used for the computation of p‐values; the method is shown to be valid both asymptotically and for moderate sample sizes. Alternative versions of the tests that take into account possible breakpoints in the marginal distributions are also investigated. Monte Carlo simulations show that the tests are powerful under many scenarios of change‐point. In addition, two estimators of the time of change are proposed and their efficiency is carefully studied. The methodologies are illustrated on simulated series from the Canadian Regional Climate Model. The Canadian Journal of Statistics 41: 65–82; 2013 © 2012 Statistical Society of Canada  相似文献

Approximately 33% of the homeless population in 2017 were families with children. Researchers have argued for interventions and services to employ an ecological perspective to mitigate some of the unintentional harm inherent in existing programs designed to serve homeless families. This paper utilized a case study of a transitional housing program to (1) determine how well the program met recommendations informed by the ecological perspective and (2) explore underlying themes across recommendations. Past and current residents of a transitional housing program participated in semi-structured interviews as part of a program evaluation. Interviews were deductively and inductively coded to meet aims 1 and 2, respectively. Residents identified several aspects of the program that met the ecological perspective recommendations including culturally-responsive services, trauma-based services, and social and community connections. Major underlying themes spanning across recommendations included interpersonal resources (caring, sense of belonging), empowerment resources (advocacy, family preservation), impact on family (family life, positive youth development), and communication. This case study, through the analysis of residents’ perspectives, highlights the important role of transitional housing programs in providing a supportive, empathetic, empowering, and home-like environment that gives residents “back that dignity” so they are emotionally and physically prepared to successfully transition to permanent housing.  相似文献

Play offers rich opportunities for toddlers to develop motor, social, cognitive, and language skills, particularly during interactions with adult caregivers who may scaffold toddlers to higher levels of play than toddlers achieve on their own. However, research on play has narrowly focused on children from White, middle‐income backgrounds, leaving a dearth of knowledge about dyadic play in diverse cultural communities. We videorecorded 222 Mexican‐American mothers playing with their 2‐year‐old toddlers with a standard set of toys. Play behaviors were coded as nonsymbolic or symbolic (play type) and as expressed through manual, verbal, or multiple channels (play modality). Play between toddlers and mothers was frequent, high in symbolic content, and toddler play closely corresponded with mother play in type and modality: Toddlers’ nonsymbolic play related to mothers’ nonsymbolic play; toddlers’ symbolic play related to mothers’ symbolic play; toddlers’ manual play related to mothers’ manual play; and toddlers’ multimodal play related to mothers’ multimodal play. Play in Mexican‐American mothers and toddlers is frequent, multimodal, and symbolically rich, offering new directions for future research and practice.  相似文献

Gambia, the smallest country on the African continent, is one of the largest contributors, per capita, to irregular migrants in Europe. Aspirations to migrate are ingrained culturally, to the extent that they can be understood as a rite of passage. Unfilled rites, associated with involuntary immobility, have led to pervasive frustration and feelings of entrapment, locally referred to as having the nerves syndrome. This article explores the societal and cultural significance of migration in this context, exploring the meanings that this especially has for effective migration management. It provides evidence and context for the deep motives, embedded socially and culturally, for migration as a significant mechanism to maintain status and achievement of adulthood. In view of this, initiatives by foreign and domestic governments and NGOs to work on campaigns and strategies to entice citizens to remain and work at home should be carefully considered. Foreign policies and funds to so-called empower youth to stay in their home countries may be misleadingly ineffective. The academic literature does not sufficiently address this.  相似文献

This article follows from the workshop that Professor Mireille Paquet organized in Montreal in June 2018, to discuss my book, The New Politics of Immigration and the End of Settler Societies (Cambridge, 2016; Dauvergne 2016). In relation to this event and the articles of this special issue, this paper embarks on revisiting The New Politics of Immigration, now more than three after it first appeared in print. In this paper, I reflect on whether my arguments stand up to the test presented by the events of the past three years. Recent events lead me to nuance some of my original arguments, but on the whole even the most recent surprises fit well into the New Politics framework that points to increasing salience, legalization and urgency in politicizing immigration.  相似文献

This article illustrates some of the ways in which the notion of (paid) work is actively being gendered, and how these gendering processes take place not only through organizational practices but also in discourses that circulate outside an organization in the private domain. Drawing on 15 in‐depth interviews with women who opted out of their own professional career in order to accompany their husbands on their overseas work assignment to Hong Kong, we demonstrate some of the benefits of using a discourse analytical approach to capturing and identifying the processes through which these women actively (although not necessarily consciously) gender the notion of work, thereby reinforcing the gender order and its male bias. We argue that identifying and making visible these gendered and gendering practices is an important component of, and a potential trigger for, change both in organizations as well as private contexts.  相似文献
