Developing a tailored substance use intervention for youth exiting foster care

Youth who are aging out of the foster care system face significant barriers to accessing substance use treatment. Mobile interventions have shown efficacy for several mental and physical health issues and may be helpful in overcoming barriers facing foster youth with substance use problems. A program (iHeLP) for substance use reduction was developed that used a computerized screening and brief intervention (SBI) followed by six months of dynamically-tailored text messages. The program was shown to focus groups of youth (N = 24) ages 18–19 who recently left foster care and had moderate to severe substance use risk. Focus group feedback was used to modify iHeLP prior to delivery in an open trial (N = 16). Both study phases included assessments of feasibility and acceptability; the open trial also included assessments of substance use outcomes at 3 and 6 months. Focus groups indicated a high level of acceptability for the proposed intervention components. Of those screened for the open trial, 43% were eligible and 74% of those eligible enrolled, indicating good feasibility. Retention through the final follow-up was 59%, and drop out was associated with involvement in the criminal justice system. Participant ratings for liking, ease of working with, interest in and respectfulness of the SBI were high. Satisfaction ratings for the texting component were also high. A computerized brief screening intervention for substance use risk reduction together with tailored text messaging is both feasible and highly acceptable among youth who have recently aged-out of foster care.     

Effects of mobile apps for nursing students: learning motivation,social interaction and study performance

Abstract

This study examined the effects of mobile apps on the learning motivation, social interaction and study performance of nursing students. A total of 20 students participated in focus group interviews to collect feedback on their use of mobile apps for learning and communicative activities. Two consecutive cohorts of students in a nursing programme, each with about 200 students, were recruited for assessing their learning motivation through a survey and study performance by two tests. The results showed that the students actively used the mobile apps for studying supplementary materials as well as participating in in-class activities and clinical assessments. The students had a relatively high level of motivation for performing and learned well, but relatively low perceived satisfaction and self-efficacy with mobile learning. They showed better study performance after practising mobile learning. The results also suggest that students’ perceived intrinsic value with mobile learning has to be enhanced for improving study performance.     

Affordances of mHealth technology and the structuring of clinic communication

Careful examination of communicative outcomes of mHealth technology is critical for understanding its capacity to shape the clinical interview and structure clinic communication. Drawing on a communicative affordances framework and adopting a video-based inductive analytic approach, we extend the concept of actualizations. We do so by examining the in situ communicative actions afforded by a mHealth web interface utilized during medication titration interviews with parents of children beginning stimulant medication for ADHD. We find that the web interface served five broad communicative functions that provided opportunities for improving information accuracy and for rendering clinical reasoning transparent, while jeopardizing opportunities for parents to narrativize medication experiences. We discuss clinical, theoretical, and methodological implications.     

响应全国教育大会号召，让学生在体育锻炼中享受运动乐趣

摘要：在全国教育大会上，习近平主席面向全国教育工作者提出对学校体育工作的一系列指示，其中的“帮助学生在体育锻炼中享受运动乐趣”是对学校体育和体育课程教学的非常明确的要求，如何响应习主席的要求，让学生享受体育学习和锻炼的乐趣是本文要论述的问题。本文认为体育学习和体育锻炼失去乐趣的原因是多重的，有运动（sports）变成体育（physical education）后失去运动固有乐趣的因素，有因为体育课变得“蜻蜓点水、低级重复”后失去学习成就感的原因，有身体锻炼内容萎缩导致体育锻炼变得无味的原因等。因此，要有效地帮助学生在体育锻炼中体验运动乐趣，必须推进课程教学改革以确保学生至少熟练掌握一项运动技能，就要加强体育比赛与展示以让全体学生有展示成就的舞台，就要加大体育教学的可选择性让体育学习过程充满自发性和自主性，就要加强学习集团的互动和粘合以提高体育集体的教育作用和温暖度，就要加强快乐健身游戏内容的恢复与开发以提高体育锻炼的实效性和趣味性。在帮助学生在体育锻炼中享受运动乐趣的施策方面，本文建议要加快实验“体育走班制”教学以探索确保学生掌握技能的新课程教学模式；要学习借鉴“运动教育”的理论与实践，狠抓教、练、赛三个环节的融合；要大力普及“全员运动会”以确保全体学生都有参与竞争与表现的机会；要普及“体育趣味课课练1 260例”以大力提高体育锻炼实效性和趣味性。

科技英语被动句物称行为主体的翻译

英语被动语态在纯客观的一般性科技语体中使用很多,正是因为语体的客观性,人称行为主体(施事者)在科技英语被动句中通常不予出现,而物称行为主体则一般不能省略。本文分类分析了科技英语被动句的物称行为主体,并依据不同的行为主体所起的不同语义作用以及英汉两种语言在表现形式上的差异对其翻译技巧进行了初步的探讨。

移动助手在防汛中的应用及实现

本文介绍了一种基于智能移动终端、GPS、GIS和3G技术的水利防汛移动助手系统。该系统使用外置蓝牙GPS或内置GPS装置获取当前定位信息,并在智能移动终端中应用GIS系统进行地图标绘,通过移动传输网络将位置和现场相关数据传送至服务器,服务器对数据进行分析与存储,再将指挥指令和业务数据回传至智能移动终端,从而实现移动终端和服务器数据的实时交互。智能移动终端作为数据采集器可以进行汛情和工情信息的及时采集,服务器则对终端的位置和回传数据进行接收、查看、分析,为辅助决策提供可靠的数据依据。     

委托—代理理论——中央银行独立性(CBI)的一种解说

在中央银行独立性问题上 ,长期以来一直存在着“相机抉择论”和“单一规则论”的争论。前者旨在执行逆风向行事的货币政策以烫平经济波动 ,从而主张中央银行应依附于政府而丧失其独立性 ;而后者则主张中央银行应遵循单一规则以稳定货币币值 ,抑制通货膨胀 ,为此 ,中央银行应排除来自各方面的干扰 ,保持其高度的独立性。委托——代理理论则通过中央银行与政府的最优合同的签定 ,使中央银行既能对产出和就业波动作出适当反映 ,又能避免相机抉择政策带来的通货膨胀偏好 ,因而成为中央银行制度设计的最优方案
