This study examines the individual and contextual factors associated with sociopolitical control expressed by immigrants in southern Spain. We used hierarchical linear modeling to evaluate the relations between individual (community participation, social connectedness, and perceived cultural competence of receiving community services) and municipality characteristics (city community participation, city social connectedness, and city community services’ cultural competence) and immigrants’ feelings of sociopolitical control. Data were analyzed using a two‐level model based on 707 Moroccan immigrants in 25 municipalities. After adjusting for gender, educational level, and psychosocial confounding factors, we observed a positive association between social connectedness and sociopolitical control at the individual level. At the contextual level, we observed a positive association between (a) city community participation, (b) city social connectedness, and (c) city community services’ cultural competence, and sociopolitical control. Indeed, living in a municipality where there are community services with high levels of cultural competence and where, on average, many people participate in organizations and neighbors are connected, was associated with higher levels of perceived control in the sociopolitical domain for immigrants. We also discuss implications for community‐based research and practice.  相似文献

Previous research on children’s and adolescents’ well-being at school has been focused on the possible determinants. However, no previous research has analysed children’s and adolescents’ lay-beliefs or conceptualizations of happiness at school. In the present work, we studied children’s (N = 104, 9–10-year-olds) and adolescents’ (N = 113, 15–16-year-olds) conceptualizations of happiness at school and its link with self-reported happiness (assessed 3 months later) and academic achievement (assessed 7 months later). For both samples, seven conceptualizations emerged: happiness as ‘being with friends’, ‘being praised’, ‘getting good grades’, ‘learning’, ‘leisure’, ‘enjoyment’, and ‘helping’. Age differences appeared for the conceptualizations of ‘being friends’ and ‘helping’, as children mentioned significantly more the former and adolescents the latter. No gender differences emerged. For adolescents, the conceptualizations of happiness at school as ‘being with friends’, ‘being praised’, ‘helping’, and not ‘having leisure time’ were positively related to self-reported happiness, which was positively related to academic achievement. For children, none of the conceptualizations were positively related to self-reported happiness. The conceptualization of happiness as ‘learning’ was positively related to academic achievement. The results are discussed in regards to their implications for children’s and adolescents’ well-being at school.  相似文献

Anodal transcranial direct current stimulation (tDCS) induces long-term potentiation-like plasticity, which is associated with long-lasting effects on different cognitive, emotional, and motor performances. Specifically, tDCS applied over the motor cortex is considered to improve reaction time in simple and complex tasks. The timing of tDCS relative to task performance could determine the efficacy of tDCS to modulate performance. The aim of this study was to compare the effects of a single session of anodal tDCS (1.5 mA, for 15 min) applied over the left primary motor cortex (M1) versus sham stimulation on performance of a go/no-go simple reaction-time task carried out at three different time points after tDCS—namely, 0, 30, or 60 min after stimulation. Performance zero min after anodal tDCS was improved during the whole course of the task. Performance 30 min after anodal tDCS was improved only in the last block of the reaction-time task. Performance 60 min after anodal tDCS was not significantly different throughout the entire task. These findings suggest that the motor cortex excitability changes induced by tDCS can improve motor responses, and these effects critically depend on the time interval between stimulation and task performance.  相似文献

The aim of this paper was to develop an instrument to assess levels of stress experienced by Latin-American immigrants in their acculturative process in Spain. A sample of 692 immigrants from Latin America, aged 20 to 63 years, took part on this study (54.9% males and 45.1% females). A 24-item questionnaire with high reliability (.92) was elaborated. Six factors related to acculturative stress were found: 1) discrimination and rejection; 2) differences with the out-group (native Spaniards); 3) citizenship problems and legality; 4) problems concerning social relationships with other immigrants; 5) nostalgia and longing; and 6) family break-up. Our findings show that participants have a high level of stress related to nostalgia and longing, family break-up, and the perception of discrimination and rejection by natives. The usefulness of the instrument and its applications and restrictions are discussed.  相似文献

The aim of this work is to carry out a dimensional proposal for the assessment of humor appreciation. First, theoretical frames on sense of humor and particularly on humor appreciation are presented. These theoretical frames are related to the methodological characteristics of studies centered to assess humor appreciation. Then, it is justified the creation of a new scale, and it is specified the aim of assessment and the target population which this new scale is focused on. Finally, a dimensional proposal it is concretized and analyzed by a group of experts. Their judgments are presented and they are analyzed considering reviewed empirical and theoretical works. The results support some theoretical validity evidences of this dimensional proposal about humor appreciation.  相似文献

Effect of manipulating the risetime of an acoustic stimulus on two protective reflexes: cardiac defense and motor startle. The risetime is a parametric characteristic of the eliciting stimulus frequently used to differentiate among psychophysiological reflexes. The aim of the present study was to examine the effect of manipulating the risetime of an acoustic stimulus on two protective reflexes: cardiac defense and motor startle. 100 participants underwent a psychophysiological reactivity test to five presentations of an intense acoustic stimulus (105 dB white noise) under one of five risetime conditions: 0, 24, 48, 96, and 240 ms. Total energy of the stimulus was controlled by increasing the base duration of the stimulus (1000 ms) by one third of the risetime. Results showed that risetime significantly affected motor startle but not cardiac defense. Startle amplitude decreased linearly with increasing risetime after 24 ms. On the other hand, repetition of the stimulus significantly affected cardiac defense but not motor startle. These results question the traditional differentiation between startle and defense based on risetime.  相似文献

The "Cuestionario de Intereses Profesionales (CIP, Vocational Interests Questionnaire)" was developed by Fogliatto et al in three different versions: a paper and pencil-based one, a computer-based one, and a revised form. The instrument was originally created for the assessment of vocational interests of adolescents assisting the last years of the secondary school in Argentina. The aim of the present study was to adapt the inventory for the adolescents coursing the initial period of the secondary school. Psychometric studies analyzing the factorial structure of the instrument and internal consistence of their scales were accomplished. Additionally, evidences of criterion validity concerning to a specialized field of the secondary school and career choice intentions were analyzed. Results bring initial validity evidence of this new version of the CIP, which its main utility is career counseling applied to late-adolescence. Further studies are required in order to validate this instrument for being utilized in counseling of adolescent facing decisions related to specialty choice of the secondary school.  相似文献

Estrous behavior in rodents is triggered by the binding of progesterone (P) to its intracellular receptor (PR). Non-steroidal agents (i.e., gonadotropin-releasing hormone, noradrenaline, dopamine and others), acting at the membrane, can facilitate estrous behavior in estrogen-primed rats. This action is mediated through the generation of second messengers (cyclic AMP, cyclic GMP, calcium) which, in turn, phosphorylate through diverse kinase systems (protein kinases A, G or C) either the PR or associated effector proteins linking the PR to the trans-activation machinery. P or its metabolites also activate cyclic AMP-signaling pathways by acting directly on the membrane or by modulating neurotransmitter release. Molecular processes resulting from second messenger signaling pathways and those from the progesterone-RP interaction synergize to elicit a full behavioral response.  相似文献
