With the increase in substance use by young people in recent years' there has been a growth in evidence‐based programs aimed at preventing this problem. This study aims to assess possible changes in family and parental dynamics among families taking part in a short (6‐session) universal program. These changes might act as protective factors for families in preventing substance use. A quasi‐experimental design was used' with pretest and posttest evaluations. The participating schools meeting the inclusion criteria were randomly assigned to the experimental or control group. The sample was made up of 16 experimental groups and 17 control groups' with the participation of 353 parents and 289 youths. The results confirm the strengthening of the families by improving the following key components of parenting: resilience' involvement' family conflicts' and positive parenting. Reinforcing parenting skills through a short program is a good strategy to take' ensuring high levels of adherence (86.40% retention of the initial sample). Hence future universal prevention programs must not just set their sights on high levels of effectiveness' but also on efficiency.  相似文献

With the growing number of sexually transmitted infections (STIs) among young people (15–24) in the US, condom distribution programs (CDP) remain an integral part of prevention strategies. The objective of the study was to gather qualitative insights from CDP planners to inform effective CDP implementation. Ten semi-structured interviews with program planners were conducted via telephone (response rate of 58.8%). Condom distribution channels included site-based distribution (n = 6), web-based distribution (n = 4), and distribution via Uber (n = 1). Site-based distribution programs had distribution networks ranging from 100 to 3500 sites in a given jurisdiction. Planners of site-based CDPs experienced challenges with ensuring quality control at sites and supplying condoms to sites. Web-based CDPs allow individuals to order free condoms online. These CDP planners reported growing demand for this discreet service, particularly among young people. Web-based CDPs leveraged e-mail surveys to collect data on sexual behavior and behavior change, yielding response rates as high as 63%. All CDPs emphasized the importance of supplying a variety of products. Total supplies distributed (male condoms, internal condoms, lubricant sachets) ranged from 16,000 to 45 million per year. Novel channels of distribution should be explored to ensure reach to adolescents and young adults.  相似文献

Blockmodeling refers to a variety of statistical methods for reducing and simplifying large and complex networks. While methods for blockmodeling networks observed at one time point are well established, it is only recently that researchers have proposed several methods for analysing dynamic networks (i.e., networks observed at multiple time points). The considered approaches are based on k-means or stochastic blockmodeling, with different ways being used to model time dependency among time points. Their novelty means they have yet to be extensively compared and evaluated and the paper therefore aims to compare and evaluate them using Monte Carlo simulations. Different network characteristics are considered, including whether tie formation is random or governed by local network mechanisms. The results show the Dynamic Stochastic Blockmodel (Matias and Miele 2017) performs best if the blockmodel does not change; otherwise, the Stochastic Blockmodel for Multipartite Networks (Bar-Hen et al. 2020) does.  相似文献

"体教结合"战略为我国培养出综合型人才,但目前的"体教结合"战略不能有效的在非中心城市实施,建立科学、合理、新型的体制,成为进一步推进非中心城市竞技体育发展的核心问题。随着社会经济的发展,"体教结合"战略思想也应与时俱进。非中心城市普通高校与其当地体育运动学校结合,共同达到提高竞技体育水平的目的;地方教育资源和体育资源相结合,优势互补,实现"双赢"。  相似文献

Massive Open Online Courses (MOOCs) have gained traction as resources for professional development. This article presents the method that we used to evaluate a professional development MOOC for postdoctoral trainees that was created by a university consortium in the US. Most approaches to evaluating MOOCs focus on analysis of participation, outcomes from course assignments, self-reported learning outcomes, course completion and user pathways through the online content or clickstream data. Few published evaluations describe in detail how learning happens within online courses and the anticipated medium and longer term cognitive and behavioral outcomes on participants. This work aims to guide those who are designing, implementing and evaluating MOOCs through applying theories of change to focus evaluation on the process of learning. This approach can be used as a complement to traditional approaches for evaluating MOOCs. We described how we worked with the MOOC team building the content to develop a theory of change for each module (or lesson) within the MOOC and used the theory of change to guide evaluation of short and medium term participant cognitive, affective and attitudinal, and behavioral outcomes. Finally, we share lessons learned and suggestions for implementing theories of change in both the design and evaluation phases of MOOC development.  相似文献

With more than 28 active members, the Mediterranean Engineering Schools Network (RMEI) is the most active network on gender equality in the Mediterranean area. Supported by the HORIZON2020 TARGET project ‘Taking a Reflexive Approach to Gender Equality for Institutional Transformation’, in conceptualizing gender equality learning and system change, the network took a context-specific approach based on a theory of change and other STEM organizational frameworks, to design a self-assessment framework and indicators, considering the systemic view of SDG5 horizontally connected to all SDGs, national context complexity, and transdisciplinary requirements. 95 simple, practical, user-friendly indicators were designed, fitting in the specificities of the Mediterranean-Engineering context. The analysis showed that the network realized its vision, made the ‘passage’ from theory to praxis on gender equality change, effectively developed meaningful processes/structures, formulated a policy statement, built a community of practice and inspired members. It also achieved trustful relationships and inspired outputs, effective communication, sharing of information and resources, and top management commitment. Critical aspects are a) the analysis in depth of issues linked to the existence of gender-based stereotypes and bias in engineering schools of the Mediterranean that entails tackling gender ideologies considering the whole national social system and existing structures; b) sustainability of gender equality structures created at the member institutions with the support of TARGET project which is depending on the willingness of institution’s leaders to continue/advance with gender-sensitive strategies in their institution.  相似文献

传统史学研究,经常把史学的范围和目的搞得非常狭隘,非常肤浅,以至于写成君、臣的家谱,把读者引入歧途.历史研究要讲究科学性原则,要接受和借鉴自然科学和社会科学的研究方法,要用进化的眼光考察历史的变化,将过去的事实予以新意义或新价值.通过对史学研究的改革,给现代人们以新的借鉴.  相似文献
