Historians, archivists, and social activism: benefits and costs 总被引：1，自引：1，他引：0
This article explores how activism by historians and archivists relates to and affects their work and how their work affects their activism. The findings are based on a survey of 195 historians (including educators) and archivists who self-identified as “someone who takes part in activities that are intended to achieve social or political change, especially someone who is a member of an organization.” The respondents participate in a wide variety of causes. Typically, their activities as activists reflect their professional skills and concerns, with a large majority involved in collecting and preserving the records of activist organizations. The article examines the benefits and costs for employers of employee activism, concluding the benefits outweigh the costs. The article also examines how activism affects the relationship between employers and their activist employees. While many activists receive recognition and other benefits from their employers for their activism, a minority suffers negative consequences up to and including firing and a substantial number feel inhibited from activism by their employers. The article also explores the effects of activism for the different occupational groups, determining that they are relatively similar but with some differences. 相似文献

Three waves of data from a prospective longitudinal study in Sierra Leone were used to examine internalizing trajectories in 529 war‐affected youth (ages 10–17 at baseline; 25% female). Latent class growth analyses identified 4 trajectories: A large majority of youth maintained lower levels of internalizing problems (41.4%) or significantly improved over time (47.6%) despite very limited access to care, but smaller proportions continued to report severe difficulties 6 years postwar (4.5%) or their symptoms worsened (6.4%). Continued internalizing problems were associated with loss of a caregiver, family abuse and neglect, and community stigma. Despite the comparative resilience of most war‐affected youth in the face of extreme adversity, there remains a compelling need for interventions that address family‐ and community‐level stressors. 相似文献

Rural communities in the Haut-Uele Province of northern Democratic Republic of Congo live in constant danger of attack and/or abduction by units of the Lord's Resistance Army operating in the region. This pilot study sought to develop and evaluate a community-participative psychosocial intervention involving life skills and relaxation training and Mobile Cinema screenings with this war-affected population living under current threat. 159 war-affected children and young people (aged 7–18) from the villages of Kiliwa and Li-May in north-eastern DR Congo took part in this study. In total, 22% of participants had been abduction previously while 73% had a family member abducted. Symptoms of post-traumatic stress reactions, internalising problems, conduct problems and pro-social behaviour were assessed by blinded interviewers at pre- and post-intervention and at 3-month follow-up. Participants were randomised (with an accompanying caregiver) to 8 sessions of a group-based, community-participative, psychosocial intervention (n = 79) carried out by supervised local, lay facilitators or a wait-list control group (n = 80). Average seminar attendance rates were high: 88% for participants and 84% for caregivers. Drop-out was low: 97% of participants were assessed at post-intervention and 88% at 3 month follow-up. At post-test, participants reported significantly fewer symptoms of post-traumatic stress reactions compared to controls (Cohen's d = 0.40). At 3 month follow up, large improvements in internalising symptoms and moderate improvements in pro-social scores were reported, with caregivers noting a moderate to large decline in conduct problems among the young people. 相似文献

This study examined the prospective influence of adolescent working memory (WM) on changes in impulsivity and sexual risk taking and assessed whether this relation could be explained by confounding effects of parental influences. Data from 360 community adolescents (Mage = 13.5 ± 0.95 years; 52% female; 56% non‐Hispanic White; low‐mid socioeconomic status (SES); recruited from Philadelphia area in 2004–2005) were analyzed using structural equation modeling to predict changes in impulsivity and sexual risk taking over a 2‐year follow‐up, using baseline assessments of WM, parental monitoring, parental involvement, and SES. Stronger WM predicted reduced involvement in sexual risk taking at follow‐up, effects channeled through changes in impulsivity dimensions of “acting without thinking” and “inability to delay gratification.” Parental variables had a protective influence on adolescent impulsivity and risk involvement, but the effects of WM operated independently of parental influences. 相似文献

To carry out effective teaching/learning processes, lecturers in a variety of educational institutions frequently need support. They therefore resort to advice from more experienced lecturers, to formal training processes such as specializations, master or doctoral degrees, or to self-training. High costs in time and money are invariably involved in the processes of formal training, while self-training and advice each bring their own specific risks (e.g. of following new trends that are not fully evaluated or the risk of applying techniques that are inappropriate in specific contexts).This paper presents a system that allows lecturers to define their best teaching strategies for use in the context of a specific class. The context is defined by: the specific characteristics of the subject being treated, the specific objectives that are expected to be achieved in the classroom session, the profile of the students on the course, the dominant characteristics of the teacher, and the classroom environment for each session, among others. The system presented is the Recommendation System of Pedagogical Patterns (RSPP). To construct the RSPP, an ontology representing the pedagogical patterns and their interaction with the fundamentals of the educational process was defined. A web information system was also defined to record information on courses, students, lecturers, etc.; an option based on a unified hybrid model (for content and collaborative filtering) of recommendations for pedagogical patterns was further added to the system. RSPP features a minable view, a tabular structure that summarizes and organizes the information registered in the rest of the system as well as facilitating the task of recommendation. The data recorded in the minable view is taken to a latent space, where noise is reduced and the essence of the information contained in the structure is distilled. This process makes use of Singular Value Decomposition (SVD), commonly used by information retrieval and recommendation systems. Satisfactory results both in the accuracy of the recommendations and in the use of the general application open the door for further research and expand the role of recommender systems in educational teacher support processes. 相似文献

Working memory (WM) is positively correlated with socioeconomic status (SES). It is not clear, however, if SES predicts the rate of WM development over time or whether SES effects are specific to family rather than neighborhood SES. A community sample of children (n = 316) enrolled between ages 10 and 13 completed four annual assessments of WM. Lower parental education, but not neighborhood disadvantage, was associated with worse WM performance. Neither measure of SES was associated with the rate of developmental change. Consequently, the SES disparity in WM is not a developmental lag that narrows or an accumulating effect that becomes more pronounced. Rather, the relation between family SES and WM originates earlier in childhood and is stable through adolescence. 相似文献

The Salisbury University Libraries embarked on a serials and database cancellation project in the 2014–2015 academic year, eventually cutting nearly 20% of journals without causing any faculty protests. Picking up ideas from numerous other libraries, the three-person project task force developed a three-stage process: 1) preparation—gathering data and laying the groundwork for getting feedback; 2) getting feedback from liaisons, faculty, and departments; and 3) making decisions about what to cut and sharing the results. This article details the steps taken and key recommendations for other libraries undertaking similar projects. 相似文献
