Although the relationship between negative childhood experiences, peer victimization, depressive symptoms, and Non-Suicidal Self-Injury (NSSI) is widely recognized, the mechanisms involved are not fully understood, especially among adolescents. This study aims to test the mediating role of both self-criticism and depressive symptoms in the relationship between memories of negative or positive experiences, current peer victimization, and NSSI. The sample consists 854 Portuguese adolescents, 451 female and 403 male, with ages between 12 and 18 years (M = 14.89; SD = 1.79), from middle and secondary schools. Participants answered self-report measures. Results from path analysis showed that memories of negative experiences, the absence of positive memories with family in childhood and peer victimization indirectly impact on NSSI through self-criticism and depressive symptoms. In addition, these stressful experiences led to depressive symptoms through self-criticism. Lastly, the most severe form of self-criticism indirectly impacts on NSSI through depressive symptoms, even though it also has a strong direct effect. It suggests that negative experiences with parents and peer victimization, as well as the absence of positive memories with family, have a negative impact on NSSI when these experiences are linked with a sense of self-hatred and depressive symptoms.  相似文献

The present study examines whether early experiences of threat, subordination and devaluation with family influence adolescents’ negative emotional states and subsequently deliberate self-harm; and if this effect is conditioned by daily peer hassles. The sample consisted of 441 adolescents (57.6 % female) with ages between 13 and 18 years old from middle and high schools. Participants completed self-report instruments measuring early memories of threat, subordination and devaluation, daily peer hassles, negative affect and deliberate self-harm behaviors. Results from conditional process analysis showed that adolescents who feel devalued and experience threat and submission within family tend to endorse high levels of negative affect, which in turn accounts for increased endorsements on deliberate self-harm. Moreover, the impact of negative affect on deliberate self-harm is amplified by the presence of moderate and high levels of daily peer hassles. This study suggests the relevance of assessing and intervening on type of emotional memories (i.e., threat, subordination and devaluation), daily disruptions with peers and negative emotional states with adolescents who self-injure. These findings may be useful in the development of preventive and intervention programs for reducing deliberate self-harm in adolescence.  相似文献

This paper studies the economic effect of immigration on native working conditions, focusing on the impact of the inflow of immigrant labour on occupational mobility among native workers. Basing on a gender-segmented labour market, we propose an extension of the model presented by Peri and Sparber American Economic Journal: Applied Economics, 1(3), 135-169, (2009). The model controls for gender and time in order to check for potential differences in immigration effects associated with gender or immigrant length of residence. This research reveals the existence of such differences, by showing that female immigrant inflow has a greater positive short-term impact on occupational mobility among female unskilled native workers. In addition, the long-term study discloses a slight occupational assimilation of male immigrants towards employment patterns of male native workers and a permanent confinement of female immigrants in a few “niche jobs”.  相似文献

In the last two decades, temporary worker programs have experienced an unprecedented expansion as instruments of what is defined as the migration management approach. Various migrant rights activists have voiced concerns about the treatment of temporary migrants in these programs and taken initiative to advance their rights. For some migrant rights advocates, it is the temporary nature of migration that is primarily responsible for the rights deficit. Yet, other migrant rights activists accept the temporariness of labour migration while trying to ensure that migrants receive legal protections for their work rights and that these protections are enforced. Trade unions are among the actors who try to protect and advance temporary migrants’ labour rights, but their role in supporting or challenging the principles of temporary migration governance has been neglected in the scholarly literature. The article addresses this gap by highlighting the divergent position of Canadian and Spanish Unions on temporariness of this type of migration. As the article argues, the difference is related to the following four factors: (1) the degree to which the unions in question are institutionally embedded in immigration policy-making, (2) the social environment (that is, discourses on temporariness advanced by other unions and grassroots organizations), (3) the degree of protectionism unions express vis-à-vis new immigrant flows and (4) whether regulated temporary migration is contrasted with permanent or unauthorized migration.  相似文献

Early math skills are determined by higher cognitive processes that are particularly important for acquiring and developing skills during a child's early education. Such processes could be a critical target for identifying students at risk for math learning difficulties. Few studies have considered the use of a structural equation method to rationalize these relations. Participating in this study were 207 preschool students ages 59 to 72 months, 108 boys and 99 girls. Performance with respect to early math skills, early literacy, general intelligence, working memory, and short‐term memory was assessed. A structural equation model explaining 64.3% of the variance in early math skills was applied. Early literacy exhibited the highest statistical significance (β = 0.443, < 0.05), followed by intelligence (β = 0.286, < 0.05), working memory (β = 0.220, < 0.05), and short‐term memory (β = 0.213, < 0.05). Correlations between the independent variables were also significant (< 0.05). According to the results, cognitive variables should be included in remedial intervention programs.  相似文献

Narrative theories of personal identity have traditionally taken literary characters as models to better understand how our identities are constituted through the narratives of our lives. However, there have been several recent criticisms of these comparisons, showing that philosophers of personal identity paid no attention to the nature of literary characters, and consequently, these philosopher’s comparisons were under-motivated. In the present article, I rely on a cognitive framework to define literary characters. From that point of view, I assert that it is fruitful to compare ourselves with literary characters to understand the role that the narratives told by others about ourselves play in the constitution of our own personal identities.  相似文献
