A 3‐layered backpropagation connectionist network, configured as an autoassociator, learned to form global (e.g., mammal) before basic‐level (e.g., cat) category representations from perceptual input. To test the predicted global‐to‐basic order of category learning of the network, 2‐month‐olds were administered the familiarization/novelty‐preference procedure and examined for representation of global and basic‐level categories. Infants formed a global category representation for mammals that excluded furniture but not a basic‐level representation for cats that excluded elephants, rabbits, or dogs. The empirical results are consistent with the global‐to‐basic learning sequence observed in the network simulations.  相似文献

This article offers self‐body‐care as an aspect of corporate moderate feminism and a manifestation of postfeminism for women leaders. It explains how postfeminism as a bodily practice surfaces through women leaders' body work and how women ‘top' leaders strategize to stabilize their credibility by identifying their own and other women' body work needs and the steps they take to meet these. Self‐body‐care extends understandings of body work as part of postfeminist governmentality and contributes to understandings of moderate feminism as that which deflects and reflects feminism and constrains and empowers subjects. As such self‐body‐care offers an (im)perfect space for disruption and for Gender and Organization Studies (GOS) scholars to pursue the implications and potential of postfeminism. We call for women elite leaders to be part of feminist futures and illustrate self‐body‐care as an aspect of corporate moderate feminism by highlighting complexity in the postfeminist thesis and reflexively re‐examining two of our previous published empirical studies of women ‘top' leaders.  相似文献

Age‐at‐arrival is a key predictor of many immigrant outcomes, but discussion continues over how to best measure and study its effects. This research replicates and extends a pioneering study by Myers, Gao, and Emeka [International Migration Review (2009) 43:205–229] on age‐at‐arrival effects among Mexican immigrants in the U.S. to see if similar results hold for other immigrant groups and in other countries. We examine data from the 2000 U.S. census and 2006 American Community Survey, and 1991, 2001, and 2006 Canadian censuses to assess several measures of age‐at‐arrival effects on Asian immigrants’ socioeconomic outcomes. We confirm several of Myers et al.’s key findings, including the absence of clear breakpoints in age‐at‐arrival effects for all outcomes and the superiority of continuous measures of age‐at‐arrival. Additional analysis reveals different age‐at‐arrival effects by gender and Asian ethnicity. We suggest guidelines, supplementing those offered by Myers et al., for measuring and studying age‐at‐arrival’s effects on immigrant outcomes.  相似文献

Memory based on a one‐time experience is an important element of its definition as “episodic.” Infants' memories for one‐time experiences over long delays are largely unexplored. Using elicited imitation, we tested 20‐ and 16‐month‐olds' (Experiment 1) and 13‐month‐olds' (Experiment 2) memories as a function of number of experiences and delay. Over 1 month, 20‐ and 16‐month‐olds remembered individual actions of one‐time events; 20‐month‐olds also remembered temporal order; with verbal reminders, 16‐month‐olds did as well. Over 3 months, recall depended on multiple experiences. Thirteen‐month‐olds' required multiple experiences, even over 1 month. The findings speak to the gradual emergence of an important element of episodic memory, namely the ability to preserve memories of one‐time experiences over long periods of time.  相似文献

The purpose of the current study was to examine the validity and reliability of (Journal of Marital and Family Therapy 2003, 29, 209) Differentiation of Self Inventory‐Revised (DSI‐R; Skowron & Schmit, 2003) in Turkish adults. The DSI‐R was translated, independently back‐translated, and revised. Two independent samples of adults over the age of 25 were used. The original 46‐item DSI‐R was not supported by the data derived from Sample 1 (n = 221). However, a revised 20‐item, four‐factor model fit the data well. This 20‐item model was subsequently cross‐validated with a second sample of Turkish adults (n = 187). Scale scores showed adequate internal consistency, 5‐week test–retest reliability, and satisfactory convergent and criterion‐related validity. It was concluded that Turkish DSI‐R (DSI‐T) is a valid and reliable measure to assess an individual's differentiation level. In light of the findings, implications for the use of the DSI‐T and ideas for future research are discussed.  相似文献

The author used a new longitudinal data set, the How Couples Meet and Stay Together surveys (N = 3,009), to generate the first nationally representative comparison of same‐sex couple stability and heterosexual couple stability in the United States. He measured the association between marriage (by several definitions of marriage) and couple longevity for same‐sex couples in the United States. Reports of same‐sex relationship instability in the past were due in part to the low rate of marriages among same‐sex couples. After controlling for marriage and marriage‐like commitments, the break‐up rate for same‐sex couples was comparable to (and not statistically distinguishable from) the break‐up rate for heterosexual couples. The results revealed that same‐sex couples who had a marriage‐like commitment had stable unions regardless of government recognition. A variety of predictors of relationship dissolution for heterosexual and for same‐sex couples are explored.  相似文献

For the United States generally, a positive relationship has been found between occupational social status and migration propensity. However, the addition of two variables has greatly altered this relationship. The strength of the relationship for blacks was much weaker than for whites. The relationship disappeared for both races for interregional (South/non‐South) migration. More blue‐collar migration from the South to the non‐South was counteracted by more white‐collar migration from the non‐South to the South. Implications of these findings for the so‐called push‐pull theory of migration as well as public policies are discussed.  相似文献

One potential consequence of rising top‐income concentration is borrowing by less‐affluent households attempting to maintain relative living standards. This paper evaluates the “keeping up with the Joneses” phenomenon, examining the responsiveness of payment‐to‐income ratios for different debt types across the income distribution to changes in income among affluent households. The analysis provides evidence for the responsiveness of debt to rising top incomes. Middle‐ and upper‐middle‐income households take on more housing‐related debt and have higher payments in places with higher top‐income levels. Among lower‐income households non‐mortgage borrowing and debt payments decline, consistent with restrictions in the supply of credit. (JEL D63, D14)  相似文献

A sample of 182 young adults about to choose their college major were randomly assigned to 2 guidance methods aimed at facilitating choosing among promising career alternatives: Table‐for‐Choice and Circles‐for‐Choice. Table‐for‐Choice was perceived as more effective, but individuals' confidence in their choice was higher in the Circles‐for‐Choice condition. More factors that serve to compare and evaluate the options were listed by participants in the Circles‐for‐Choice condition. No interaction emerged between the participant's decision‐making style and the usefulness of the two methods. Both methods were perceived as more useful for participants who were already at the choice stage than for those who were only at the prescreening or the in‐depth explorations stage.  相似文献

We used data from the Midlife Development in the United States (MIDUS I) (N = 2,031) to compare three models of how work‐family conflict and enrichment might operate to predict well‐being (mental health, life satisfaction, affect balance, partner relationship quality). We found no support for a relative‐difference model in which the conflict‐enrichment balance predicted outcomes. In the work‐to‐family direction, the additive model fit best: Both work‐to‐family conflict and work‐to‐family enrichment were independently linked to outcomes. In the family‐to‐work direction, the interactive model fit best: Family‐to‐work enrichment buffered the negative outcomes ordinarily linked to family‐to‐work conflict. Enrichment is key because with the additive model, it contributed incremental explanatory power, and with the buffering model, it conditioned conflict‐outcome relationships. Work‐to‐family conflict and family‐to‐work enrichment appeared particularly salient for well‐being.  相似文献

This study examines the cultural‐transmission effects of compensatory‐discrimination affirmative action policies on work‐ethic preference dynamics for a population in a caste‐based segregated economy in which some high‐paid jobs are reserved for historically disadvantaged lower‐caste individuals. Cultural attitudes toward preferences for work‐loving and leisure‐loving traits evolve endogenously. The compensatory‐discrimination policies affect differently the preference dynamics for insiders (entitled to employment quota) and outsiders (not entitled to employment quota). Efficient and inefficient equilibria are possible, with larger or smaller proportions of individuals with a work ethic among the insider and outsider populations. The model shows that the commonly conceived conclusion that a job reservation policy benefits a disadvantaged group at the cost of efficiency and economic growth is not a necessary outcome.

This study investigated associations of low‐income working mothers' daily perceived workload and their reports of their own mood and their interactions with their young children. Sixty‐one mothers were asked to report on their workload, mood, and interactions with their preschool‐age children every day for 2 weeks (N = 520 work days). Low‐income mothers reported significant day‐to‐day variability in workload. The results revealed a curvilinear pattern of negative work‐to‐family spillover: Both lower‐than‐average and higher‐than‐average workload days were associated with increased negative and tired mood, decreased positive mood, and increased harsh mother–child interactions. Although both younger and older mothers experienced a curvilinear pattern of spillover to daily mood, younger mothers in the period of emerging adulthood also experienced spillover to mother–child interactions, perhaps because they are still learning how to balance work and family demands. Both high and low workload are salient stressors in the daily lives of low‐wage working mothers.  相似文献

Ego‐resiliency is an enduring psychological construct reflecting how individuals‐adapt to environmental stressors, conflict, and change which is linked to positive adjustment. Ego‐resiliency has not been examined in Latino youth, despite their high risk for mental health problems; nor have cultural precursors to ego‐resiliency been examined. Given these gaps, we examined whether familism values (supportive, obligation, and referent) were associated with ego‐resiliency and, in turn, depressive problems in Latino adolescents across two time points (N = 123, mean age = 11.53). Results indicated that supportive familism was associated positively with ego‐resiliency and negatively with depressive problems. Ego‐resiliency negatively predicted depressive problems across time, controlling for prior levels, suggesting that ego‐resiliency may have long‐term effects on depressive problems in Latino youth.  相似文献

Briefly Noted     
The U.S. Preventive Services Task Force (USPSTF) recommends that primary care clinicians provide interventions, including education or brief counseling, to prevent initiation of tobacco use among school‐aged children and adolescents. However, there is not enough evidence to recommend tobacco‐cessation interventions in this population, according to the draft recommendation, released in June. The USPSTF is not part of the U.S. government, but its recommendations are taken into consideration by clinical and payer organizations. It only makes recommendations for interventions when it has found adequate evidence that the interventions do more good than harm. In the case of tobacco interventions, the task force found no evidence at all of harms of providing behavioral prevention interventions. However, once kids are already using nicotine, there is not enough evidence to recommend for or against cessation options. The recommendations were first published in the Annals of Internal Medicine and in Pediatrics in 2013; the final draft recommendations were issued in June, for public comment by July 22.

Pre‐birth risk assessment is a process by which circumstances affecting an unborn child can be identified and support for mother and infant embedded. This mixed methods study describes a community‐based pre‐birth assessment and care pathway that utilised the Parents Under Pressure (PuP) programme to assess parenting capacity and provide support pre‐ and post‐birth for ‘at risk’ women. Sixty‐eight pregnant women referred to children's social care services were allocated to the pre‐birth assessment and care pathway (n = 35) or to routine care (n = 33). Standardised measures of psychological distress, social support and alcohol measured change for the women in the assessment and care pathway. Twenty women who provided pre‐ and post‐data reported significant improvements on all measures except alcohol use. Safeguarding outcomes at 12 months were obtained for both groups using administrative data. Forty‐two per cent of the infants whose mothers received the pre‐birth assessment and care pathway showed an improvement in child protection status compared to 14 per cent of the routine care infants. Safeguarding status deteriorated or stayed the same in 52 per cent of the routine cases compared to 26 per cent of those receiving the pathway. Qualitative data revealed that the pathway was acceptable and helpful to service users and service providers. Copyright © 2017 John Wiley & Sons, Ltd.

Key Practitioner Messages

  • The current project found that a community‐based pre‐birth assessment and care pathway with high‐risk pregnant women was feasible and acceptable for practitioners and service users.
  • The pathway began mid‐pregnancy and support was provided following the birth of the infant for up to 12 months.
  • Over 40 per cent of infants whose mothers were allocated to the pre‐birth risk assessment pathway showed improvements in child safeguarding status at 12 months.

When mothers speak to infants at risk for developmental dyslexia, they do not hyperarticulate vowels in their infant‐directed speech (IDS). Here, we used an innovative cross‐dyad design to investigate whether the absence of vowel hyperarticulation in IDS to at‐risk infants is a product of maternal infant‐directed behavior or of infants’ parent‐directed cues. Interactions between mothers and infants who were at risk or not at risk for dyslexia were recorded in three conditions: when mothers interacted with (a) their own infants, (b) infants who were not their own but of the same risk status, and (c) infants who were not their own and of the opposite risk status. This design revealed both infant and parent effects. Mothers of not‐at‐risk infants hyperarticulated vowels significantly more when speaking to not‐at‐risk than to at‐risk infants. In contrast, mothers of at‐risk infants hyperarticulated vowels significantly less than NAR mothers, and this was irrespective of infant status. Mothers of not‐at‐risk infants thus adjusted their IDS to the infant's risk status, while mothers of at‐risk infants did not. We suggest that IDS is determined reciprocally by characteristics of both partners in the dyad: Both infant and maternal factors are essential for the vowel hyperarticulation component of IDS.  相似文献

This study investigated the relation between maternal contingent responsiveness and 4‐ and 5‐month‐old infants' (N = 64) social expectation behavior in a still‐face procedure. Mothers were asked to interact with their infants for 2 min (interactive phase), remain still‐faced for 1 min (still‐face phase), and resume interaction for 2 min. Mother and infant behavior was assessed for the frequency of infant and mother smiles, mother smiles that were contingent to infant smiles and infant smiles were contingent to mother smiles during the interactive phase, and infant social bids to mother during the still‐face phase. Hierarchical regression showed that mother contingent smiles during the interactive phase accounted for unique variance in infant social bids during the still‐face phase beyond that accounted for by the frequency of mother and infant smiles during the interactive phase. These results support the view that young infants' social expectations and sense of self‐efficacy are formed within their interactions with their caregivers.  相似文献

This study explores 12‐month‐olds' understanding of face‐to‐face conversation, a key contextual structure associated with engagement in a social interaction. Using a violation‐of‐expectations paradigm, we habituated infants to a “face‐to‐face” conversation, and in a test phase compared their looking times between “back‐to‐back” (conceptually novel) and “face‐to‐face” (conceptually familiar) conversations, while simultaneously manipulating perceptual familiarity in a 2 × 2 factorial design. We also analyzed dynamic changes in pupil dilation, which are considered a reliable measure of cognitive load that may index processing of social interactions. Infants looked relatively longer at perceptual changes (new speaker positions) but not at conceptual change (back‐to‐back conversation), suggesting that face‐to‐face conversation may not elicit particular expectations, and so may not carry any particular conceptual significance. Moreover, on the first test trial, larger pupil dilation was observed for familiar conditions, suggesting that familiarity with perceptual features could enhance processing of conversations. Thus, this study undermines assertions regarding infants' conceptual understanding of the social signals underlying engagement. Infants may rather recognize such signals through their perceptual familiarity and associated positive feelings. This may then increase their engagement when observing and participating in others' collaborative activities, in turn allowing for the development of knowledge regarding others' intentions.  相似文献

This paper studies the extent and variation in production cost pass‐through for U.S. outsourcing imports. Data from 4,676 products imported through the U.S. overseas assembly program show that outsourcing imports were characterized by incomplete pass‐through of production and trade costs to import prices. Notably, pass‐through was higher for products assembled in high education countries while the response of outsourcing import prices to competing suppliers' prices was largest for products sold by firms in capital‐intense industries. The reasons for these cross‐country and cross‐industry differences, as they relate to theories of outsourcing and trade, are explored. (JEL F1, F2)  相似文献

Previous research highlights the influence of therapist factors on treatment outcomes. One therapist factor proposed as fundamental to the process of therapy is the therapist's way‐of‐being, a relational concept that refers to how the therapist regards a client—either as a person or object (Fife et al., [2014] Journal of Marital and Family Therapy, 40, 20–33). Although this case has been made conceptually, there is little empirical research on therapists’ way‐of‐being with clients. The primary purpose of this research is to investigate clients’ perceptions of their therapists’ way‐of‐being. Utilizing a common factors perspective, the study seeks to explore: (a) how clients experience their therapists’ way‐of‐being and (b) the influence therapists’ way‐of‐being has on clients’ engagement. Phenomenological methods were used to gain a nuanced understanding of the phenomenon. Qualitative data were collected through semi‐structured face‐to‐face interviews with clients (N = 10) who received individual therapy from a marriage and family therapist. Results were organized into two main themes: core tenets (attunement, congruency, and aligning with clients) and operational tenets (providing affirmation and validation, balancing flexibility and structure, and accomplishing goals). Findings are used to make a case for adding the concept of way‐of‐being as an overarching construct for several well‐established therapist factors. Clinical and training implications are discussed.  相似文献
