The objective of this study was to determine whether children's characteristics and/or institutional characteristics were predictors of severe punishments (including beatings) and/or frequency of punishments that children received from staff in Romanian institutions. The data was hierarchical with institutionalized children (N = 1391) nested within 44 institutions, and the measurement of punishments by the staff and frequency of punishments had a binary distribution. Thus, multilevel logistic regression models were used to examine the effects of individual and institutional level variables on reported punishments and to account for the clustering of the children within institutions. Two general patterns of results emerged. First, regarding individual level variables, it was found that: (1) amount of time spent by children in their current institutions had a significant effect on the probability of being punished by staff and the frequency of this punishment; (2) the probability of being punished was higher for boys than for girls; and (3) having no siblings in the institution increased the odds of being punished several times. Second, regarding institutional level variables: (4) being in placement centers for school-aged children with a traditional type of institutional organization increased the odds of severe punishment compared to a familial/mixed type. The results of the present study highlight the importance of understanding the consequences of institutionalization in a broader way, where children not only experienced early severe psychosocial deprivation as documented in other studies, but also high levels of severe punishments administered by institutional staff.  相似文献

In order to assess familial resemblance for measures of reading performance, data from 314 pairs of twins in which at least one member of each pair is reading-disabled [142 monozygotic (MZ) and 172 dizygotic (DZ) twin pairs], 273 matched control pairs (131 MZ and 142 DZ pairs), and their parents were subjected to both correlation and regression analyses. Results indicate that parent-offspring resemblance in families of reading-disabled probands does not differ substantially from that in families of controls. In general, the correlations and regressions for MZ twin pairs are greater than those for DZ twins; thus, individual differences in reading performance are due at least in part to heritable influences. As expected, regression coefficients are consistently larger than correlation coefficients for both parent-offspring and proband-cotwin comparisons in the reading-disabled sample, illustrating that regression analyses are more appropriate than correlations for assessing familial resemblance in selected samples.  相似文献

The blood-brain barrier (BBB) is a critical structure that serves as the gatekeeper between the central nervous system and the rest of the body. It is the responsibility of the BBB to facilitate the entry of required nutrients into the brain and to exclude potentially harmful compounds; however, this complex structure has remained difficult to model faithfully in vitro. Accurate in vitro models are necessary for understanding how the BBB forms and functions, as well as for evaluating drug and toxin penetration across the barrier. Many previous models have failed to support all the cell types involved in the BBB formation and/or lacked the flow-created shear forces needed for mature tight junction formation. To address these issues and to help establish a more faithful in vitro model of the BBB, we have designed and fabricated a microfluidic device that is comprised of both a vascular chamber and a brain chamber separated by a porous membrane. This design allows for cell-to-cell communication between endothelial cells, astrocytes, and pericytes and independent perfusion of both compartments separated by the membrane. This NeuroVascular Unit (NVU) represents approximately one-millionth of the human brain, and hence, has sufficient cell mass to support a breadth of analytical measurements. The NVU has been validated with both fluorescein isothiocyanate (FITC)-dextran diffusion and transendothelial electrical resistance. The NVU has enabled in vitro modeling of the BBB using all human cell types and sampling effluent from both sides of the barrier.  相似文献

In drawing from social role theory and the match-up hypothesis, the purpose of this study was to determine influential variables regarding the effectiveness of female athlete endorsers. A 2 (gender appropriate/gender inappropriate) × 2 (sport related product/non-sport related product) experiment was conducted with 296 participants from four different universities throughout the United States. Results indicated that type of sport had little effect on credibility measures. Further, the athlete's sport had no effect on athlete-product fit. The most important aspect relative to purchase intentions was the product being endorsed, not the sport in which the athlete competed. Results are discussed in terms of practical implications and theoretical considerations.  相似文献

Each of us has a personal narrative: a story that defines us, and one that we tell about ourselves to our inner and outer worlds. A strong sense of identity is rooted in a personal narrative that has coherence and correspondence (Conway in J Mem Lang 53:594–628, 2005): coherence in the sense that the story we tell is consistent with and supportive of our current version of ‘self’; and correspondence in the sense that the story reflects the contents of autobiographical memory and the meaning of our experiences. These goals are achieved by a reciprocal interaction of autobiographical memory and the self, in which memories consistent with the self-image are reinforced, in turn strengthening the self-image they reflect. Thus, personal narratives depend crucially on the malleable nature of autobiographical memory: a strong sense of self requires that one remember what matters, and forget what does not. Today, anyone who is active online generates a highly detailed, ever—expanding, and permanent digital biographical ‘memory’—memory that identifies where we go, what we say, who we see, and what we do in increasing detail as our physical lives become more and more enmeshed with electronic devices capable of recording our communications, online activities, movements, and even bodily functions. This paper explores the consequences of this digital record for identity, arguing that it presents a challenge to our ability to construct our own personal narratives–narratives that are central to a sense of ‘self’. In the end, the ‘right to be forgotten’ may be, above all else, a psychological necessity that is core to identity—and therefore a value that we must ensure is protected.  相似文献

Self‐management interventions have been adapted to serve as targeted interventions to increase academic enabling behaviors in groups of students. However, a trade‐off exists between adapting these interventions to feasibly fit group contexts and maintaining theoretical intervention components. This study examines the use of self‐management within fourteen 40‐minute group counseling sessions delivered by school psychology personnel to increase the academic enabling behaviors of three middle school students as rated by their teachers. Results of a multiple baseline design across students revealed slight to moderate improvements in academic enabling behaviors for two of the three students. Furthermore, usability results suggested that students found the intervention to be generally acceptable, understandable, and feasible. Implications for both future research and applied practice are discussed.  相似文献

Parental autonomy support has been related to positive adolescent outcomes, however, its relation to outcomes in collectivist cultural groups is unclear. This study examined relations of specific autonomy supportive behaviors and outcomes among 401 adolescents (Mage = 12.87) from the United States (= 245) and collectivist-oriented Ghana (= 156). It also examined whether adolescents’ self-construals moderated the relations of specific types of autonomy support with outcomes. Factor analyses indicated two types of autonomy support: perspective taking/open exchange and allowance of decision making/choice. In both countries, perspective taking/open exchange predicted positive outcomes, but decision making/choice only did so in the United States. With regard to moderation, the more independent adolescents’ self-construals, the stronger the relations of decision making/choice to parental controllingness and school engagement.  相似文献

Chinese leaders have attempted to alleviate international anxiety about its rise to global prominence describing its development as a ‘peaceful rise’ or ‘peaceful development’. Most recently, Chinese leaders have begun deploying a new term, the ‘New Style of Great Power Relations’ (新型大国关系). The purpose of this study is to examine the treatment of the ‘New Style of Great Power Relations’ as a political slogan within the Chinese media as a means to shape a geopolitical worldview among Chinese citizens and international actors. Researchers identified 541 articles from 25 different Chinese media sources selected to represent varying levels of government influence and editorial perspectives. This study found the concept primarily intended to engage the United States by stressing cooperative aspects of U.S.–China relations, but also challenges specific U.S. actions. Those U.S. policies challenged within the Chinese media are portrayed as inconsistent with the ‘new style’ concept’s principles. This forms a ‘rhetorical trap’, as it were for the United States, in that the framing of the discourse implicates U.S. intentions and policies as disingenuous unless the United States changes its policy stances. The essay examines the implications of the discourse for understanding Chinese political communication.  相似文献

This study tested whether a 17-day randomized controlled expressive writing (EW) intervention improved cancer caregivers’ emotion regulation ability and if improved emotion regulation predicted increases in verbal person-centered message characteristics present in caregivers’ recalled support conversations with cancer survivors. Participants (N?=?64) were spousal caregivers of hematopoietic stem cell transplant cancer survivors assigned to one of three writing conditions: traumatic disclosure (TD), benefit finding (BF), or a time-management control. Caregivers completed writings three times at one-week intervals, along with pre- and posttest reports of emotion regulation and written accounts of supportive conversations with spousal survivors. Both EW conditions (TD and BF) predicted reduced emotion regulation difficulty compared to the control condition. Cognitive, pronoun, and positive affect word usage within EWs did not predict emotion regulation improvement. However, use of negative emotion words predicted significant increases in emotion regulation difficulty across conditions. Verbal person-centeredness (VPC) message characteristics significantly increased from pre- to posttest for those assigned to the BF and control conditions. Despite change in VPC, emotion regulation did not mediate the relationship between condition assignment and message characteristic outcomes.  相似文献
