The effectiveness of a language-training procedure that emphasized reinforcing vocal “reasonable attempts” (any response directed at an interventionist and within a broader class of correct responses) was compared with a procedure that emphasized shaping (reinforcing successive approximations that more closely resembled the target vocalization). Three preschoolers who had been diagnosed with autism spectrum disorders participated in the study. Data indicated that the children mastered vocal skills more rapidly when they learned through shaping than in the reasonable attempts condition. Implications for teaching children with autism spectrum disorders are discussed. 相似文献

We investigated associations between retrospectively assessed timing of pubertal development, interpersonal interactions, and hypothalamic–pituitary–adrenal axis reactivity to an interpersonal stress task in 110 young adult women. Participants provided salivary cortisol samples at points prior and subsequent to a video‐taped conflict discussion with their romantic partner. Participants also provided subjective global ratings of their discussion on dimensions of conflict and support. For earlier developing girls, higher levels of interpersonal conflict were associated with greater physiological stress in anticipation of the discussion task and less physiological recovery following the discussion. In contrast, for later developing girls, low levels of conflict were associated with greater anticipatory stress and less physiological recovery. These findings have implications for understanding the influence of off‐time pubertal development on the lifetime development of young women. 相似文献

Abstract In this paper, current notions of “labeling theory” are faulted for being overly inclusive and lacking theoretical specificity. In response to this, a delimitation of labeling, to the naming process, is proposed and a four stage processual conceptualization is offered relative to that delimited notion of labeling. This reconceptualization features a multi-process model involving: typing, designating; assessing; and resisting labels. Following the model overview, typing, the first stage in the sequence is examined in greater detail. Target associated appearances, consequences, responsibility, and values, are considered, as these affect typings. The impact of existing typings on subsequent typings is also examined and the problematics of assessing target information from others is considered, as well as conditions influencing confidence in target typings. 相似文献

In this article, we propose a general method for testing the Granger noncausality hypothesis in stationary nonlinear models of unknown functional form. These tests are based on a Taylor expansion of the nonlinear model around a given point in the sample space. We study the performance of our tests by a Monte Carlo experiment and compare these to the most widely used linear test. Our tests appear to be well-sized and have reasonably good power properties. 相似文献

The Experience-Earnings Profile: Productivity-Augmenting or Purely Contractual? Evidence from the UK
William J. Moore Robert J. Newman Geoffrey K. Turnbull 《Journal of Labor Research》2007,28(3):417-435
We test the human capital interpretation of the experience-earnings profile. Does the upward sloping portion of the experience-earnings
profile reflect on-the-job training which in turn causes the experience-productivity profile to slope upwards, or do purely
contractual factors determine the nature of life-cycle earnings. Herein, we provide additional evidence on the relationship
between productivity and earnings by examining earnings differentials in the UK academic labor market for economists. Using
a test first suggested by Mincer, we find that the empirical results are consistent with human capital theory. We find that,
although the positive relationship between earnings and experience persists when individual productivity measures are included
in the salary equations for lecturers and senior lecturers, the positive relationship becomes statistically insignificant
when the same productivity measures are included in the salary equations for professors. For lecturers and senior lecturers,
the experience-salary profile properly reflects the structure of the national pay scale rather than variations in individual
research productivity. At the professor level, where individual salaries are not determined by a pay scale, the data support
the human capital explanation of the positive experience-earnings profile.

Social, cultural, and institutional processes which see heterosexuality as natural and universal discriminate against individuals who differ from this norm. This article draws on interviews with lesbian, gay, bisexual, and transgender (LGBT) people in Swaziland to provide an enhanced understanding of the ways in which heterosexism operates in practice and impacts the sexual rights of LGBT communities in Swaziland, where same-sex practices are criminalised. These narratives show the importance of solidarity and activism in coping strategies to challenge social exclusion, improve lives, and advocate for social changes. These strategies include reframing, navigating interpersonal relationships, and advocacy. We consider key lessons that emerge from our research for policy, programmes, and activism in Swaziland, as well as other low- and middle-income contexts. 相似文献

Qualified competences in social science and humanities are required across the various deliverables of the intergovernmental science-policy platform on biodiversity and ecosystem services (IPBES) in order to fully address the objectives of IPBES. Building integrative approaches has long been acknowledged as a scientific challenge. Hence, new paths have to be forged, including revisiting basic ontological and epistemological considerations, such as how we understand the world, what knowledge is, and the role of science. Constructive interdisciplinary dialogues in IPBES supports the development of innovative frames and terminologies. One example is the evolution from the Millennium Ecosystem Assessment ecosystem service framework to the Nature’s Contributions to People classification now applied in IPBES assessments. IPBES is still in a learning phase and critical examination of what is accomplished this far is useful when refining ongoing modes of work and in long-term strategic considerations. 相似文献
