A gender perspective has been incorporated in transnational migration studies over the last two decades in Spain. According to feminist inquiry, research has focused mainly on four areas: transnational maternities, transformation in global care regimes, multiple discrimination experiences and change in gender relations by means of migration. In this paper, we suggest that there is a fifth area that has been neglected: one that studies the ways in which governmentality practices, performed within service provision aimed at migrant populations, are enacted in host societies. We argue that mechanisms of categorisation developed in service provision in Spain contribute to the construction of the category of “Third World Women”. A set of discourses and practices that are based on gender and cultural assignation related with stereotyped understandings of migrated women in host societies, situating them as suitable workers for current care regimes within these societies. These mechanisms have an important impact on life situations experienced by many migrated women as they are integrated into a low waged and undervalued work market. Further developments must be made in this last area of inquiry from a critical standpoint, in order to avoid the reproduction of discriminatory practices within institutional intervention settings. 相似文献

Cognitive assessments and behavioral ratings of attention were used to examine the relation of inattention to math performance in children. Third grade students with math difficulties (MD; n?=?17) and math and reading difficulties (MDRD; n?=?35) were administered the Attentional Network Test (ANT), as well as achievement and intelligence measures. Strengths and Weaknesses of ADHD-Symptoms and Normal-Behavior-IV (SWAN-IV) Inattention ratings were collected from teachers. Two comparison groups were also recruited: a typically achieving group (n?=?23) and a group that responded to a math-tutoring intervention (responders; n?=?54). On the ANT, children with MD and MDRD did not perform significantly different than typically achieving children or responders on measures of alerting and orienting attention and executive control. All subgroups did demonstrate performance patterns that were expected on the ANT. However, performance across blocks of the task was inconsistent, suggesting poor reliability. There were no relations between ANT performance and SWAN-IV behavioral inattention scores, though behavioral ratings of inattention correlated significantly with math performance. Children with MD and MDRD may have more difficulty with distraction and attention to detail in contextual situations, as opposed to impulsive responding in these settings. The lack of relation between cognitive attention and math performance may suggest that either the ANT does not assess the relevant attention constructs associated with math difficulties or may parallel studies of attention deficit/hyperactivity disorder (ADHD) in which cognitive and behavioral assessments are weakly related. 相似文献

Reversing arrows in the classic tri-variate X-M-Y mediation models as a test to check whether one mediation model is superior to another is inadmissible. Presenting evidence that one tri-variate mediation model yields a significant indirect effect, whereas one with some reversed arrows does not, is not proof or even evidence that one model should be preferred. In fact, the significance of the indirect or any other effect can never be used to infer whether one model should be preferred over another, if the models are in the same so-called equivalence class. The practice of running several mediation models with reversed arrows to decide which model to prefer should be abandoned. The only way to choose among equivalent models is through assumptions that are either fulfilled by design features or invoked based on theory. Similar arguments about reversing arrows in mediation models have been made before, but this current work is the first to derive this result analytically for the complete (Markovian) equivalence class of the tri-variate mediation model. 相似文献

This study compares the effectiveness of a violence prevention program with young, at-risk children in two settings. Preschool and kindergarten students, residing in Chicago public-housing developments, participated in a 28-session intervention. Knowledge, behavior problems, and social skills were assessed at pretest and posttest, based on child interviews, teacher ratings, and behavioral observations. Findings suggest that both preschool and kindergarten children demonstrated significant gains in knowledge, based on interview scores, and significant decreases in problem behaviors, based on behavioral observations; however, teacher ratings did not change significantly across time. The discrepancy in findings is explored and implications are discussed. 相似文献

Very fast extraction of global structural and statistical regularities allows us to access the “gist”—the basic meaning—of real-world images in as little as 20 ms. Gist processing is central to efficient assessment and orienting in complex environments. This ability is probably based on our extensive experience with the regularities of the natural world. If that is so, would experts develop an ability to extract the gist from the artificial stimuli (e.g., medical images) with which they have extensive visual experience? Anecdotally, experts report some ability to categorize images as normal or abnormal before actually finding an abnormality. We tested the reality of this perception in two expert populations: radiologists and cytologists. Observers viewed brief (250- to 2,000-ms) presentations of medical images. The presence of abnormality was randomized across trials. The task was to rate the abnormality of an image on a 0–100 analog scale and then to attempt to localize that abnormality on a subsequent screen showing only the outline of the image. Both groups of experts had above-chance performance for detecting subtle abnormalities at all stimulus durations (cytologists d' ≈ 1.2 and radiologists d' ≈ 1), whereas the nonexpert control groups did not differ from chance (d' ≈ 0.23, d' ≈ 0.25). Furthermore, the experts’ ability to localize these abnormalities was at chance levels, suggesting that categorization was based on a global signal, and not on fortuitous attention to a localized target. It is possible that this global signal could be exploited to improve clinical performance. 相似文献

Mediation analysis, or more generally models with direct and indirect effects, are commonly used in the behavioral sciences. As we show in our illustrative example, traditional methods of mediation analysis that omit confounding variables can lead to systematically biased direct and indirect effects, even in the context of a randomized experiment. Therefore, several definitions of causal effects in mediation models have been presented in the literature (Baron &; Kenny, 1986; Imai, Keele, &; Tingley, 2010; Pearl, 2012). We illustrate the stochastic theory of causal effects as an alternative foundation of causal mediation analysis based on probability theory. In this theory we define total, direct, and indirect effects and show how they can be identified in the context of our illustrative example. A particular strength of the stochastic theory of causal effects are the causality conditions that imply causal unbiasedness of effect estimates. The causality conditions have empirically testable implications and can be used for covariate selection. In the discussion, we highlight some similarities and differences of the stochastic theory of causal effects with other theories of causal effects. 相似文献

Preschoolers' selective learning from adult versus peer models was investigated. Extending previous research, children from age 3 were shown to selectively learn simple rule games from adult rather than peer models. Furthermore, this selective learning was not confined to preferentially performing certain acts oneself, but more specifically had a normative dimension to it: children understood the way the adult demonstrated an act not only as the better one, but as the normatively appropriate/correct one. This was indicated in their spontaneous normative interventions (protest, critique, etc.) in response to third party acts deviating from the one demonstrated by the adult model. Various interpretations of these findings are discussed in the broader context of the development of children's social cognition and cultural learning. 相似文献
