Guidelines to support health care professionals in early detection of, and responses to, suspected Child Abuse and Neglect (CAN) have become increasingly widely available. Yet little is known about professionals’ adherence to these guidelines or the determinants that affect their uptake. This study used a cross-sectional design to assess the adherence of Dutch Child Health Care (CHC) professionals to seven key activities described in a national guideline on preventing CAN. This study also examined the presence and strengths of determinants of guideline adherence. Online questionnaires were filled in between May and July 2013 by 164 CHC professionals. Adherence was defined as the extent to which professionals performed each of seven key activities when they suspected CAN. Thirty-three determinants were measured in relation to the guideline, the health professional, the organisational context and the socio-political context. Bivariate and multivariate regression analyses tested associations between determinants and guideline adherence. Most of the responding CHC professionals were aware of the guideline and its content (83.7%). Self-reported rates of full adherence varied between 19.5% and 42.7%. Stronger habit to use the guideline was the only determinant associated with higher adherence rates in the multivariate analysis. Understanding guideline adherence and associated determinants is essential for developing implementation strategies that can stimulate adherence. Although CHC professionals in this sample were aware of the guideline, they did not always adhere to its key recommended activities. To increase adherence, tailored interventions should primarily focus on enhancing habit strength. 相似文献

Engagement in problem‐solving and mathematical discussion is critical for learning mathematics. This research review describes a gap in the literature surrounding engagement of students with Learning Disabilities in standards‐based mathematical classrooms. Taking a sociocultural view of engagement as participation in mathematical practices, this review found that students with LD were supported towards equal engagement in standards‐based mathematics through multi‐modal curriculum, consistent routines for problem‐solving, and teachers trained in Mathematical Knowledge for Teaching. Using this small set of studies (7), we identify the need to deepen the engagement of students with LD in mathematical problem‐solving and discussion. This review concludes with implications for teaching and learning. 相似文献

This article features a study that explored the presence of adverse childhood experiences (ACEs), including childhood sexual abuse and neglect, among women associated with Partnership for Peace (PfP), the first and only culturally adapted domestic violence diversion program for men in the Eastern Caribbean. Within a multiyear evaluative study that assessed the impact of the PfP intervention in reducing domestic violence in Grenada in the West Indies, life-history interviews were collected from a subsample of women (N = 9) associated with men enrolled in the PfP program between 2009 and 2011. We found that the exposure to sexual abuse and neglect during childhood was evident in the histories of the women. Most perpetrators were trusted family or community members who suffered from a common set of behavioral patterns, most prominently alcohol use. Our findings reflect an evidence-based connection, as one causative factor, of a culture of silence that is related to child sexual abuse and its management. The apparent lasting effects of these traumatic childhood exposures reflect cycles of abuse in the life histories collected during the domestic violence evaluation study. Our study identified three key structural deficiencies (insufficient research, ineffective policy, and lack of public-health interventions) and one embedded cultural norm (the culture of silence) that together “inhibit current attempts to address ACEs as a means of curbing domestic violence in the Caribbean.” 相似文献

This study examined the presence and strengths of determinants associated with consultation of an in-house expert on child abuse and neglect (CAN) by preventive child health care professionals who suspect CAN. This study also assessed the relationship between in-house CAN expert consultation and professionals’ performance of six recommended activities described in a national guideline on preventing CAN for preventive child health care professionals. A total of 154 professionals met the study’s inclusion criteria. They filled in a questionnaire that measured in-house consultation practices and twelve determinants associated with the professional, the in-house expert, and the organizational context. Bivariate and multivariate regression analyses were performed. Almost half of the participants (46.8%) reported to consult the in-house expert in (almost) all of their suspected CAN cases. Professionals who reported better recollection of consulting the in-house expert (i.e. not forgetting to consult the expert) (p = .001), who were more familiar with consultation (p = .002), who had more positive attitudes and beliefs about consultation (p = .011) and who reported being more susceptible to the behavior (p = .001) and expectations/opinions (p = .025) of colleagues regarding in-house expert consultation were more likely to consult the in-house expert. Furthermore, in-house expert consultation was positively associated with two of six key guideline activities: consulting the regional child protection service and monitoring whether support was provided to families. The implications of these results for improving professionals’ responses to CAN are discussed. 相似文献

通过对Excel中VLOOKUP函数进行剖析,以学生体质健康评价为例,对VLOOKU函数进行调用实验。研究发现VLOOKUP函数可以有效提高学生体质健康评价的准确性和工作效率。但在应用时务必正确设置函数参数,避免出现批量错误。另外,VLOOKUP函数灵活性较大,应用时人为误差和失误率会加大,专业、人性、智能的学生体质健康评价软件需进一步普及推广。 相似文献

ABSTRACTIntroduction: Low energy availability (LEA) results in physiological adaptations, which can contribute to unfavourable health outcomes. Little information exists on risk of LEA in active individuals competing in different sports or levels of competition. The aims of this study were to (1) identify risk of LEA in females competing at different levels of competition and (2) investigate associations between risk of LEA, illness and dietary habits. Methods: The validated questionnaire, ‘Low Energy Availability in Females Questionnaire’ was distributed online (November 2016–February 2017) to assess risk of LEA. Twenty-nine additional questions collected information on demographics, illness history and dietary habits. Participants were considered at risk of LEA if they attained a score of?≥?8 and were grouped into: (i) international; (ii) provincial/inter-county; (iii) competitive; and (iv) recreationally active. Chi-square and logistic regression analyses were used to explore differences between those at risk or not at risk of LEA. Results: Risk of LEA was identified in 40% (n?=?331) of 833 participants and was 1.7 and 1.8 times more likely in international and provincial/inter-county athletes compared to those who were recreationally active (International: odds ratios (OR) 1.68, 95% confidence intervals (95%CI) 1.12–2.54; Provincial/inter-county: OR 1.83, 95%CI 1.20–2.77). In participants at risk of LEA, missing >22 days of training during the previous year due to illness occurred 3 times more frequently (OR 3.01, 95%CI 1.81–5.02). Conclusion: Risk of LEA was widespread in this heterogeneous sample. Awareness of LEA and the development of appropriate energy management strategies to ensure athlete health across levels of competition are required. 相似文献

AbstractThis opening article examines the relationship between community sport and social inclusion in research and practice. We discuss the notion of community sport, its multifarious meanings and diverse applications in different parts of the world. We further explore the conceptual and practical links between community sport and different conceptions of social inclusion. In doing so, the article draws together key themes, issues and debates addressed in the collection of articles in this special issue. We conclude by formulating implications and directions for future research and practice. 相似文献
