A growing body of literature is demonstrating associations between childhood maltreatment and bullying involvement at school. In this literature review, four potential mediators (explanatory) and three potential moderators (mitigates or exacerbates) of the association between childhood maltreatment and school bullying are proposed. Mediators include emotional dysregulation, depression, anger, and social skills deficits. Moderators reviewed include quality of parent–child relationships, peer relationships, and teacher relationships. Although there might be insurmountable challenges to addressing child maltreatment in primary or universal school-based prevention programs, it is possible to intervene to improve these potentially mediating and moderating factors.  相似文献

Many college counseling centers do not collect client data at each session because of perceived burdens. This study explored 55 clients’ and 16 doctoral counselor trainees’ experiences collecting and using data on client distress at each session over the course of counseling at a large public university's counseling center. Results indicated that the majority of both clients and counselors found the process convenient and clinically useful. Findings, clinical implications, and future directions are discussed.  相似文献

The Freedom of Information Act (FOIA) has facilitated the release of large amounts of government information that has been of great value to researchers, journalists, and other interested parties. The fraction of this information released in electronic format has been growing as has its volume. While offering great potential for research, large amounts of data disgorged from government information systems can pose challenges to human interpretation and knowledge extraction. Using the Office of the Secretary of Defense/Joint Staff Freedom of Information Act (FOIA) Logs for 2007–2009, this research identifies (1) a process for finding relationships between the FOIA requests through keywords extracted from Wikipedia and (2) a technique for visualizing these relationships in order to provide context and improve understanding when working with born-digital government data.  相似文献

We utilized a community detection approach to longitudinally (a) identify distinct groups of children with common temperament profiles in infancy and at 2 and 3 years of age and (b) determine whether co-occurrence of certain temperament traits may be early predictors of internalizing problems at 5 years of age. Seven hundred and seventy-four infants (360 girls; 88.6% White, 9.8% Hispanic, and 1.6% other races) were recruited from the Boston area. Data collection spanned from 2012 to 2021. The analysis yielded three distinct groups of children with different temperament traits and was associated with significant variation in levels of internalizing symptoms and anxiety diagnosis rate. Our findings suggest that stable temperament “communities” can be detected in early childhood and may predict risk for psychopathology later in life.  相似文献

Underidentification of students with emotional and behavioral disorders (EBD; emotional disturbance or ED in federal language) is a critical issue, perhaps explainable in part by causal attributions of problem behavior associated with conservatism. Conservatism in 58 counties in the state of California was measured by finding the percentage of voters in the county voting in favor or Proposition 8, a state constitutional amendment banning gay marriage, under the assumption that opposition to gay marriage is an indicator of conservatism. We conducted a series of hierarchical regression analyses in which conservatism, ethnicity, free/reduced lunch, and suspension/expulsion were used to explain county rates of ED, intellectual disability, and learning disability identification. The model for county identification of ED accounted for 45% of the variance from county to county, with conservatism being the strongest predictor (β = ?0.78, p < 0.001). More conservative counties had lower rates of ED identification. Other variables may contribute to under-identification, but causal attributions associated with conservatism may play a significant role.  相似文献

This research traces the development of symbol‐infused joint engagement during mother–child interactions into the preschool years. Forty‐nine children, who had been previously observed as toddlers (L. B. Adamson, R. Bakeman, & D. F. Deckner, 2004 ), were systematically observed during interactions with their mothers at ages 3½, 4½, and 5½ during activities related to the past and future, internal states, and graphic systems. Although the amount of symbol‐infused joint engagement reached a ceiling by 3½, its focus continued to become more complex and its form more balanced. Individual differences in children's symbol‐infused joint engagement were stable across 4 years. These findings highlight both how joint engagement is transformed as conversational skills develop and how it remains rooted in earlier interactions and supported by caregiver's actions.  相似文献

In higher education, doctoral training has been identified as a process of stewardship development whereby individuals learn the knowledge and skills required to advance their respective disciplines. Self-study of teacher education practices is one approach that has gained the interest of doctoral students to help them understand their own development whilst also forging recommendations for others in publications. In this self-study, we worked to understand the experiences of Shrehan, a teacher from England beginning doctoral study in the USA. Shrehan had no experience teaching at the college level prior to moving to the USA, and she saw self-study as an opportunity to understand her development and acculturation into an unfamiliar system of higher education. Data were collected through journaling, critical-friend discussions, and artefacts, as well as student data in the form of surveys, exit slips, and focus-group interviews. Qualitative data analysis of Shrehan’s experiences was guided by the four stages of acculturation theory – honeymoon, culture shock, adjustment, and recovery. Shrehan’s journey emphasizes the importance of getting to know undergraduate students and building rapport as key aspects of teaching at the college level. Self-study provided Shrehan with a heightened personal-identity awareness that increased her cultural sensitivity and broadened her worldview. Results are discussed with reference to acculturation theory and future directions for research are provided.  相似文献
