Understanding practitioners' characteristics and perspectives prior to the dissemination of an evidence-based intervention     

Baumann BL  Kolko DJ  Collins K  Herschell AD 《Child abuse & neglect》2006,30(7):771-787

OBJECTIVES: To describe the characteristics and repertoires of community practitioners serving families involved in child physical abuse that may inform training and treatment dissemination efforts. The aims are to: (a) describe the background characteristics of these clinicians; (b) document their most common intervention techniques; (c) examine clinicians' attitudes toward manualized treatment; and (d) understand the organizational climate of community agencies. METHOD: Practitioners from nine different agencies who have worked with cases in which there was child physical abuse (n=77) completed focus group discussions and three self-report questionnaires. Qualitative and quantitative analyses were conducted in tandem. RESULTS: Practitioners reported that they most often focused on family issues and employed family therapy techniques. Although treatment manuals were important, it was difficult to determine how practitioners used or would use these materials with families. An almost equal number of concerns and benefits were raised regarding using manuals in treatment. There was moderate agreement in how practitioners perceived their work environments. Age and attainment of a graduate degree were positively related to greater caring and job satisfaction, respectively, while length of time at a given agency was positively related to greater reports of emotional exhaustion on a measure of organizational climate. CONCLUSIONS: Given the promising benefits of evidence-based treatments for child abuse, it is important that researchers begin to form partnerships with community agencies that will lead to the dissemination and evaluation of effective treatment strategies.  相似文献

Personal inquiry learning trajectories in geography: technological support across contexts     

Lucinda Kerawalla  Karen Littleton  Eileen Scanlon  Ann Jones  Mark Gaved  Trevor Collins 《Interactive Learning Environments》2013,21(6):497-515

Student engagement in the design and implementation of inquiries is an effective way for them to learn about the inquiry process and the domain being studied. However, inquiry learning in geography can be challenging for teachers and students due to the complexity of scientific inquiry and the diversity of pupils' and teachers' knowledge and abilities. To address this, the Personal Inquiry project has designed a tool kit that includes nQuire, a Web-based tool to support students through the inquiry process. Here, we identify when, across five lessons comprising an inquiry into microclimates, nQuire was used by a teacher and a case study group of her 12 to 13-year-old students, and the ways in which they adopted nQuire as a tool to facilitate the creation of a coherent and cumulative inquiry learning experience over time. We found that students' use of nQuire supported them in capturing and representing their evolving understanding of inquiry, in defining and supporting their progression through the process of inquiry and in resourcing their cognitive engagement in data interpretation and representation. nQuire supported the students in accumulating and integrating new understandings across contexts and over time. In this way, nQuire successfully resourced and supported the students' learning journeys or trajectories. We conclude that nQuire can be an effective tool for supporting teachers' and students' understanding of the nature of inquiry and how to design and implement inquiries of their own.  相似文献   

Impact of age on host responses to diet-induced obesity:Development of joint damage and metabolic set points     

Kelsey H.Collins  Graham Z.MacDonald  David A.Hart  Ruth A.Seerattan  Jaqueline L.Rios  Raylene A.Reimer  Walter Herzog 《运动与健康科学(英文)》2020,9(2):132-139,197

Background:Osteoarthritis is one of the leading causes of pain and disability worldwide,and a large percentage of patients with osteoarthritis are individuals who are also obese.In recent years,a series of animal models have demonstrated that obesity-inducing diets can result in synovial joint damage(both with and without the superimposition of trauma),which may be related to changes in percentage of body fat and a series of low-level systemic inflammatory mediators.Of note,there is a disparity between whether the dietary challenges commence at weaning,representing a weanling onset,or at skeletal maturity,representing an adult onset of obesity.We wished to evaluate the effect ofthe dietary exposure time and the age at which animals are exposed to a high-fat and high-sucrose(HFS) diet to determine whether these factors may result in disparate outcomes,as there is evidence suggesting that these factors result in differential metabolic disturbances.Based on dietary exposure time,we hypothesized that rats fed an HFS diet for 14 weeks from weaning(HFS Weanling) would demonstrate an increase in knee joint damage scores,whereas rats exposed to the HFS diet for 4 weeks,starting at 12 weeks of age(HFS Adult) and rats exposed to a standard chow diet(Chow)would not display an increase in knee joint damage scores.Methods:Male Sprague-Dawley rats were fed either an HFS diet for 14 weeks from weaning(HFS Weanling) or an HFS diet for 4 weeks,starting at 12 weeks of age(HFS Adult).At sacrifice,joints were scored using the modified Mankin Criteria,and serum was analyzed for a defined subset of inflammatory markers(Interleukin-6,leptin,monocyte chemoattractant protein-1,and tumor necrosis factorα).Results:When the HFS Weanling and HFS Adult groups were compared,both groups had a similar percent of body fat,although the HFS Weanling group had a significantly greater body mass than the HFS Adult group.The HFS Weanling and HFS Adult animals had a significant increase in body mass and percentage of body fat when compared to the Chow group.Although knee joint damage scores were low in all 3 groups,we found,contrary to our hypothesis,that the HFS Adult group had statistically significant greater knee joint damage scores than the Chow and HFS Weanling groups.Furthermore,we observed that the HFS Weanling group did not have significant differences in knee joint damage scores relative to the Chow group.Conclusion:These findings indicate that the HFS Weanling animals were better able to cope with the dietary challenge of an HFS diet than the HFS Adult group.Interestingly,when assessing various serum proinflammatory markers,no significant differences were detected between the HTS Adult and HFS Weanling groups.Although details regarding the mechanisms underlying an increase in knee joint damage scores in the HFS Adult group remain to be elucidated,these findings indicate that dietary exposure time maybe less important than the age at which an HFS diet is introduced.Moreover,increases in serum proinflammatory mediators do not appear to be directly linked to knee joint damage scores in the HFS Weanling group animals but may be partially responsible for the observed knee joint damage in the adults over the very short time of exposure to the HFS diet.  相似文献   

Activity frames and complexity thinking: Honoring both public and personal agendas in an emergent curriculum     

Steve Collins  Anthony Clarke 《Teaching and Teacher Education》2008

This article which is largely conceptual in nature, explores the possibilities provided by embracing complexity thinking that are attentive to, but not confined by, externally imposed curriculum mandates while simultaneously honoring the interests and needs of individual students and the classroom collective. From this perspective, the ideas of negotiating authority, adopting a holistic view, engaging in participatory democratic practices, and using a project-based approach to learning are examined. In doing so, the concept of ‘activity frames’ is introduced and developed as a useful way of responding to curriculum mandates while being responsive to and respectful of individual and collective student learning agendas.  相似文献   

The role of Action Learning in supporting cross-cultural adaptation of international students     

Helen Collins  David Callaghan 《Action Learning: Research and Practice》2018,15(3):267-275

ABSTRACT

We explore the reflections of a lecturer using Action Learning (AL) meetings for the dissertation module on a one-year Master’s programme with a predominantly international student cohort. We focus on two concerns: to what extent does AL mitigate against the negative experiences of cross-cultural adaptation? And can we surface and share the learning that occurs when (international) scholars become practitioners and practitioners become (international) scholars? In the AL groups, many students seem more at ease with themselves, others and content in AL meetings than in other sessions. We scrutinised AL and our AL meetings to explore what makes it different and perhaps a better learning experience for the international student. This paper emerged following discussions with David, an e-learning and pedagogic specialist. Before continuing, note that there are two terms discussed in the literature: ‘cross-cultural adjustment’ and ‘cross cultural adaptation’. ‘Adjustment’ refers to minor changes to cope with when facing a new situation, ‘adaptation’ to larger scale changes [Haslberger, Arno, and Chris Brewster. 2007. “Domains of Expatriate Adjustment with Special Emphasis on Work.” Presented at the Cadiz University’s VI International Workshop on Human Resource Management, Jerez, Spain]. We suggest that AL be used more often and earlier with international students.  相似文献   

The Role of Art and Craft Collections in Teacher Training Institutions in Australia     

Penelope J. Collet 《The International Journal of Art & Design Education》2004,23(1):91-100

In postwar Australia, rapid population growth increased the demand for teachers. The colleges at Ballarat and Bendigo were revived and expanded by the Victorian Government. At Bendigo in 1955 F. M. Courtis, Head of Art Education, acquired art works initiating a valuable and significant teaching resource at the College. The study of the Courtis Collection raised obvious questions about the role of collections in the early teaching colleges and what events or factors led to their beginnings. This case study will be situated within a broader picture of art and craft collections in institutions across three states. My discussions in this paper are framed by some of Raymond Williams' notions about country and city and the ‘contrast between country and city, as fundamental ways of life’. I hope to demonstrate the important role art and craft collections have played in visual arts education in country institutions.  相似文献
