At UK institutions of higher education, the academic attainment of White students tends to be higher than that of students from other ethnic groups. A postal survey of Open University students found very little difference in academic engagement in those from different ethnic groups. The differences in pass rates and course grades remained statistically significant even when any effects of differences in academic engagement had been controlled. This is consistent with previous findings that quantitative variations in the attainment of students from different ethnic groups are not reflected in concomitant qualitative variations in their experience of higher education. The explanation for the attainment gap in ethnic minority students must be sought elsewhere than in the nature of their experience of higher education.  相似文献

Objectives

Published protocols for forensic interviewing for child sexual abuse do not include specific questions about what prompted children to tell about sexual abuse or what made them wait to tell. We, therefore, aimed to: (1) add direct inquiry about the process of a child's disclosure to a forensic interview protocol; (2) determine if children will, in fact, discuss the process that led them to tell about sexual abuse; and (3) describe the factors that children identify as either having led them to tell about sexual abuse or caused them to delay a disclosure.

Methods

Forensic interviewers were asked to incorporate questions about telling into an existing forensic interview protocol. Over a 1-year period, 191 consecutive forensic interviews of child sexual abuse victims aged 3-18 years old in which children spoke about the reasons they told about abuse or waited to tell about abuse were reviewed. Interview content related to the children's reasons for telling or for waiting to tell about abuse was extracted and analyzed using a qualitative methodology in order to capture themes directly from the children's words.

Results

Forensic interviewers asked children about how they came to tell about sexual abuse and if children waited to tell about abuse, and the children gave specific answers to these questions. The reasons children identified for why they chose to tell were classified into three domains: (1) disclosure as a result of internal stimuli (e.g., the child had nightmares), (2) disclosure facilitated by outside influences (e.g., the child was questioned), and (3) disclosure due to direct evidence of abuse (e.g., the child's abuse was witnessed). The barriers to disclosure identified by the children were categorized into five groups: (1) threats made by the perpetrator (e.g., the child was told (s)he would get in trouble if (s)he told), (2) fears (e.g., the child was afraid something bad would happen if (s)he told), (3) lack of opportunity (e.g., the child felt the opportunity to disclose never presented), (4) lack of understanding (e.g., the child failed to recognize abusive behavior as unacceptable), and (5) relationship with the perpetrator (e.g., the child thought the perpetrator was a friend).

Conclusions

Specific reasons that individual children identify for why they told and why they waited to tell about sexual abuse can be obtained by direct inquiry during forensic interviews for suspected child sexual abuse.

Practice implications

When asked, children identified the first person they told and offered varied and specific reasons for why they told and why they waited to tell about sexual abuse. Understanding why children disclose their abuse and why they wait to disclose will assist both professionals and families. Investigators and those who care for sexually abused children will gain insight into the specific barrier that the sexually abused child overcame to disclose. Prosecutors will be able to use this information to explain to juries why the child may have delayed his or her disclosure. Parents who struggle to understand why their child disclosed to someone else or waited to disclose will have a better understanding of their child's decisions.  相似文献

Objective

To explore whether adults possess implicit attitudes toward children and whether those attitudes are especially negative among respondents who are high in child physical abuse (CPA) risk.

Methods

The present study used an implicit evaluative priming procedure. In this procedure, participants were instructed to make decisions about the evaluative implications of target words. These words were preceded by photographs of child faces or adult faces displaying positive, neutral, or negative expressions. Reaction times for the evaluative decisions were used as an index of the extent to which photos invoked negative or positive evaluative reactions.

Results

Results from 2 studies, the first conducted on a student sample (N = 90) and the second on a parent sample (N = 95), demonstrated that evaluative congruence between the facial expressions displayed in photographs and the target words facilitated responses. Furthermore, the results suggested that regardless of CPA risk, child faces, relative to adult faces, facilitated responses to negative target words, suggesting an out-group bias. This implicit out-group bias was not moderated by respondents’ CPA risk status.

Conclusions

Faces of children, relative to faces of adults, appear to activate negative information structures that facilitate evaluative decisions of negative stimuli, suggesting an out-group bias. Given that out-group biases typically lead to less favorable treatment of out-group members, additional research is needed to examine the pervasiveness of negative evaluative biases towards children and the potential implications of such biases on children's lives. Further, research examining whether high CPA risk parents and low CPA risk parents differ in how they manage initial negative evaluative reactions is needed.  相似文献

Having students actively engaged with each other in discussions has become an increasingly important and common aspect of the classroom environment. This increased emphasis has also meant that instructors need to find ways to effectively and efficiently evaluate class participation. In this paper, we describe the most common method used for these assessments and highlight some of its inherent challenges. We then propose an alternative method based on peer nominations. Two case studies illustrate the advantages of this method; we find that it is both easy for students to complete and provide instructors with valuable diagnostic information with which to provide feedback and assign grades.  相似文献

This article estimates the effects of school expenditure on school performance at Key Stage 4 in England, over the period 2003–07 during which real per pupil expenditure increased rapidly. It adds to previous investigations by using dynamic panel analysis to: exploit time series data on individual schools that only recently has become available; adjust for the potential endogeneity not only of expenditure but also of other determinants of performance; and differentiate the short‐run and the (higher) long‐run attainment effects of spending changes. Consistent with other recent work, the article reports a generally significant but small effect of expenditure on school performance, but it also finds that the effect varies between specialist and non‐specialist schools, with the effect on the latter being larger. Further, the article identifies significant dynamics in the school improvement process, quantifies the long‐run effect of expenditure changes, suggests that spending effects increase with socio‐economic disadvantage, and quantifies absence effects.  相似文献

Drawing on anniversary-edition articles and interviews with journalists at Jakarta Post, Indonesia’s largest English-language news outlet, we argue that language of publication directly informs the narratives a journalistic interpretive community [Zelizer, Barbie. 1993. “Journalists as Interpretive Communities.” Critical Studies in Mass Communication 10: 219–237] develops to position itself as a news authority. Analysis showed that associations with English as a foreign language in Indonesia influenced stories of the newspaper’s professional values and practice, and the ways it conceptualized readership. The study contributes to the growing body of literature that examines intersections of journalism and language—in this case, English as a language of publication in a global context.  相似文献

Both classical and contemporary interpersonal theories have identified the social networks surrounding a couple as integral players in relational development and maintenance. The current project extends this line of research by designing (Study 1) and implementing (Study 2) a measurement of social network interdependence. Scales of network interference and facilitation are developed and probed using exploratory and confirmatory factor analysis. Results support distinct measures of network interference and facilitation. Invariance between differencing samples is tested for using multi-factor CFA. Results showed that measures of network interference and facilitation significantly vary between married and dating couples. Finally, convergent, divergent, and concurrent validity is tested for subscales using variables in relational turbulence theory. Results demonstrate that network interference and facilitation uniquely impact outcome variables above and beyond experiences of partner interference and facilitation. Results are discussed in terms of theory development.  相似文献
