Familias Unidas is an intervention that has been found to be efficacious in preventing and reducing substance use, sexual risk, and problem behaviors among Hispanic youth. While it does not specifically target youth internalizing symptoms, the intervention works to strengthen parenting and family factors associated with reduced risk of internalizing symptoms (i.e., depression, anxiety symptoms). This study examines the effects of Familias Unidas on internalizing symptoms among high‐risk youth, as well as the role of family level factors in the intervention's effects. A total of 242 12–17‐year‐old Hispanic youth with a history of delinquency and their primary caregivers were recruited from the school and juvenile justice systems, and randomly assigned to the Familias Unidas intervention or community practice control. A linear latent growth model was used to examine intervention effects on the trajectory of adolescent internalizing symptoms from baseline to 6 and 12 months post‐baseline. Results show that the Familias Unidas intervention was more efficacious than control in reducing youth internalizing symptoms. Baseline youth externalizing and internalizing symptoms did not moderate the intervention's effects on the trajectory of youth internalizing symptoms. While parent – adolescent communication did not significantly moderate the intervention's effects, changes in parent – adolescent communication mediated the intervention's effects on internalizing symptoms, showing stronger intervention effects for youth starting with poorer communication. Findings indicate that the Familias Unidas intervention can reduce internalizing symptoms among high‐risk Hispanic youth, and that improving parent – youth communication, a protective family factor, may be one of the mechanisms by which the intervention influences youth internalizing symptoms.  相似文献

Many theories of spelling development claim that before children begin to spell phonologically, their spellings are random strings of letters. We evaluated this idea by testing young children (mean age = 4 years 9 months) in Brazil and the United States and selecting a group of prephonological spellers. The spellings of this prephonological group showed a number of patterns that reflected things such as the frequencies of letters and bigrams in children’s language. The prephonological spellers in the two countries produced spellings that differed in some respects, consistent with their exposure to different written languages. We found no evidence for reportedly universal patterns in early spelling such as the idea that children write one letter for each syllable. Overall, our results reveal that early spellings that are not phonological are by no means random or universal and preserve certain patterns in the writing to which children have been exposed.  相似文献

Against a theoretical backdrop of narrative career construction, this article argues for the cultural constitution of life-designing processes in and through sport. A narrative case study approach is used to explore the culturally infused, gendered construction of elite athletic careers from the life story perspective. One Finnish, male, professional hockey player (age 29) and one Baltic, female, amateur orienteer (age 27) participated in a series of three individual interviews, generating approximately five interview hours per athlete. Both participants drew upon the performance narrative plot of an exemplary athletic career to make sense of their sporting experiences, life choices, and career behaviors. Further analysis of gendered career narrations in the context of participants' lives extended contextualized understandings of career practices, discursive resources and cultural constraints of the life design at a particular socio-historical juncture. The present study elucidates the complex social, cultural, and gendered underpinnings of athletic career, as well as the ways in which agentic individuals create novel meanings in bringing authenticity to their life through the athletic pursuit.  相似文献

The impact of food insecurity on child development in the general U.S. population is well‐established, yet little is known about the harm of food neglect relative to other types of maltreatment. Due to the harmful physiological impact of inadequate nutrients and the social impact of food‐related stress, it was hypothesized that food neglect would be more likely to impair infant cognitive and language development than physical abuse, sexual abuse, and other forms of neglect. Families of infants (N = 1,951) investigated by Child Protective Services were studied using the second cohort of the National Survey of Child and Adolescent Well‐Being (NSCAW II; NSCAW Research Group, 2002). Results from multivariable logistic regression models that controlled for likely confounding variables showed that the odds of impairment in cognition and language were significantly greater when food neglect was the most serious form of maltreatment. Considering that both food insecurity and child neglect are associated with poverty and parental mental health problems, it will be important for child welfare and mental health professionals to work collaboratively to better the health of these vulnerable children.  相似文献

Despite the continuing interest in social transitions among social scientists, there has been little analysis of the impact of societal change on personal relationships. One important factor in helping individuals deal with the stresses associated with rapid transitions is social support. In our first study, 450 manual workers, students and entrepreneurs in Russia, Georgia and Hungary completed structured questionnaires assessing demographic and value predictors of the perception of support availability and the support they obtained to deal with changes in their societies. In our second study, the same respondents participated in semi‐structured interviews investigating the relationship between their work lives and support networks. Our findings demonstrate the importance of culture, occupation and values for both the perception and reception of support, and underline the multifaceted manner in which different work experiences in different nations influence support networks.

The formation of a new venture requires crucial choices that impact the future success of the firm. An important initial decision is whether or not to start the new venture from home or from a separate location. In this paper, we examine the impact of firm-location decisions on the resource assembly process. Resource assembly is the first step taken by entrepreneurs to begin building a resource base, and it involves gaining ownership or control over resources. Our findings indicate that resource profiles significantly differ by location. In addition, away-based businesses assemble significantly higher counts of physical, financial, and organizational resources.  相似文献

Theory suggests that imagined and executed movement planning relies on internal models for action. Using a chronometry paradigm to compare the movement duration of imagined and executed movements, we tested children aged 7-11 years and adults on their ability to perform sequential finger movements. Underscoring this tactic was our desire to gain a better understanding of the age-related ability to create internal models for action requiring fine-motor movements. The task required number recognition and ordering and was presented in three levels of complexity. Results for movement duration indicated that 7-year-olds and adults were different from the other groups with no statistical distinction between 9- and 11-year-olds. Correlation analysis indicated a significant relationship between imagined and executed actions. These results are the first to document the increasing convergence between imagined and executed movements in the context of fine-motor behavior; a finding that adds to our understanding of action representation in children.  相似文献

The aim of this work was to study the effects of valence and age on visual image recognition memory. The International Affective Picture System (IAPS) battery was used, and response time data were analyzed using analysis of variance, as well as an ex‐Gaussian fit method. Older participants were slower and more variable in their reaction times. Response times were longer for negative valence pictures, however this was statistically significant only for young participants. This suggests that negative emotional valence has a strong effect on recognition memory in young but not in old participants. The τ parameter, often related to attention in the literature, was smaller for young than old participants in an ex‐Gaussian fit. Differences on the τ parameter might suggest poorer attentional performance in old participants.  相似文献

Abstract

A longitudinal study with three periods of data collection has been designed to test a model concerning the antecedents and consequences of coping in the anticipatory stage of an examination stress process. The model tested focuses on the role of positive and negative affect at an early stage as the main antecedents for coping. Primary and secondary appraisal, and dispositional variables (perceived personal competence and optimism) have been related to early affect. Moreover, the consequences of coping, considered as the affect measured after the deployment of coping strategies, and the grade obtained in the exam, are also tested. Results show that early affect is the main antecedent of displayed coping strategies. Dispositional variables and appraisal are related to affect, and differential effects of coping in later affect have been noticed. No relationship between coping and grade has been found. Implications for research on coping with examination stress are discussed.  相似文献
