Engaging mothers with substance use issues and their children in early intervention: Understanding use of service and outcomes     

《Child abuse & neglect》2018

Mothers who use substances need integrated, multi-sectoral intervention services to support substance use discontinuation. We explored mothers’ service use at Breaking the Cycle, an early intervention and prevention program for pregnant and parenting women and their young children in Toronto, Canada. We conducted retrospective analyses of families’ service records and client charts (N = 160). Aims were to 1) describe women’s use of service, 2) examine how early engagement of pregnant women related to postnatal service use, and 3) examine the circumstances in which women ended their service relationship with Breaking the Cycle. Specifically, we examined circumstances at service ending relating to women’s service goals; custody status with children; and global substance-use, parent-child relationship, and child development outcomes. We found that these vulnerable women were actively engaged in many services and for a long duration, early engagement was associated with greater service use, and greater service use was associated with more positive circumstances upon ending service. Results provide support for a relational approach to service that promotes not only the relationship between mother and child, and mother and service provider, but also highlights relationships among staff, between staff and management, and between community partners as integral to effective service delivery. Integrating positive relationships at all levels is critical to support vulnerable families with complex needs.  相似文献   

短道速滑个人项目体力分配策略研究          下载免费PDF全文

袁国庆  李文敏  黄佳儒  杨扬  郭立涛  朱永博 《体育科研》2019,(3):2-7

目的：探析短道速滑个人项目两届冬奥会及冬奥会与世锦赛体力分配策略规律差异。方法：收集整理索契、平昌冬奥会，以及2014—2017年世锦赛短道速滑个人项目相关数据，分析单圈用时、肯德尔相关系数。结果：（1）冬奥会各单项单圈用时不同程度地少于世锦赛，平昌不同程度地少于索契；（2）除2016世锦赛500 m，其他赛事均全程具有显著相关（P＜0.05）；（3）除索契冬奥会女子1 000 m，其他赛事均较早出现显著相关（P＜0.05），平昌冬奥会男子与女子均在第7、8圈为高相关（r≥0.70）；（4）平昌冬奥会1 500 m男子第12、13圈，女子第13圈为高相关（r≥0.70），两者均从第9圈开始出现显著相关（P＜0.05）。结论：500 m出发位置尤为重要，高速滑行中稳固站位能力需求突出，冬奥会中对全程维持速度能力的要求逐步提高；冬奥会1 000 m与1 500 m比赛争夺有利位置战术的实施位置较以往更为靠后。  相似文献   

基于面向对象技术的旅游用地遥感识别     

罗开盛 《中国科学院大学学报》2020,37(4):490-497

利用国产GF-1卫星影像，以南京市为例，采用面向对象技术对旅游用地信息进行专题提取，研发出基于遥感手段的旅游用地信息提取方法和流程。研究结果如下：1）GF-1夏季影像4个图层（红、绿、蓝和近红外波段）方差的平均值（VI-Summer）是识别旅游用地的有效指标。2）旅游用地提取的制图精度和用户精度分别为83.33%和73.53%，表明基于GF-1卫星影像和面向对象技术的方法能够对旅游用地进行有效识别和监测。3）南京市的旅游用地总面积为137.34 km²。4）在空间分布上，旅游用地主要集中在长江以南地区，尤其是鼓楼区、雨花台区、建邺区、玄武区和秦淮区及其附近；而长江以北（江北）地区相对稀疏。本研究结果可为利用GF-1卫星影像快速有效地监管旅游用地提供技术支撑。  相似文献   

Using an interactive platform to recognize the intersection of social and spatial inequalities     

Lisa Poling  Travis Weiland 《Teaching Statistics》2020,42(3):108-116

With the creation of interactive tasks that allow students to explore spatial ways of knowing in conjunction with their other ways of knowing the world, we create a space where students can make sense of information as they organize these new ideas into their already existing schema. Through the use of a Common Online Data Analysis Platform (CODAP) and data from Public Use Microdata Areas (PUMA), students can explore the communities in which they live and work, critically examining opportunities and challenges within a defined space.  相似文献   

挑战、困境与化解:数字环境下我国图书馆合理使用条款及其适用的再探讨     

王果  张立彬 《图书情报工作》2019,63(10):5-11

[目的/意义] 合理使用是维持著作权人个人利益与社会公共利益平衡的重要机制之一，对承担公共文化服务功能的图书馆尤为重要，但实践中图书馆的合理使用条款并未充分发挥利益平衡的作用，有必要对其存在问题及形成原因进行深入分析。[方法/过程] 通过与域外立法相比较，以及司法实践中的案例分析，可看出我国图书馆合理使用的主要问题在于现行法律规定滞后、规则不明晰，导致合理使用适用范围狭窄，还同时受到许可协议、技术措施的挤压。[结果/结论] 为化解图书馆合理使用条款的适用困境，可从增加原则性规定、明确其法律属性为强制性规定、扩大有关条款的适用范围等方面来完善立法。图书馆自身也应加强知识产权管理、提高知识产权素养，严格遵照法律规定以消除侵权隐患。  相似文献   

Adverse and adaptive childhood experiences are associated with parental reflective functioning in mothers with substance use disorder     

《Child abuse & neglect》2018

Mothers with a substance use disorder (SUD) are at risk for maladaptive parenting practices, and have heightened likelihood of having experienced childhood adversity themselves. In addition, parental reflective functioning (PRF), a capacity underlying sensitive caregiving, is often low in mothers with SUD. This study examines the relationship between PRF and aversive (emotional, physical, sexual abuse and neglect) and adaptive (safety and competence) experiences, in different developmental phases (early childhood, latency, and adolescence) in mothers with a SUD. A sample of 43 mothers with small children were interviewed with the Parental Developmental Interview to assess PRF, and they completed the Traumatic Antecedents Questionnaire regarding aversive and adaptive experiences. In addition, we used the Hopkins Symptoms Checklist-10 to control for mental health status and a battery of neuropsychological tests to control for executive functions. Results indicated that adaptive experiences in early childhood were positively related to PRF, and that experience of emotional abuse was negatively related to PRF. When separating the group of mothers in two sub-groups based on PRF level, results showed that mothers with negative to low PRF had significantly more experiences of adversities in early childhood and latency, and significantly less adaptive experiences in early childhood, latency and adolescence, compared to mothers with moderate to high PRF. In addition, mothers with adequate to high PRF reported experiencing significantly more types of adaptive experiences, and significantly less adversities compared to mothers with negative to low PRF. Results are discussed in relation to developmental trauma, resilience, epistemic trust and mistrust.  相似文献   

Assessing Determinants of Perceived Ease of Use of Institutional Repositories by Lecturers in Nigerian Universities     

Alice A. Bamigbola  Airen E. Adetimirin 《International Information and Library Review》2020,52(2):95-107

Abstract

Institutional repositories (IRs) present platform to disseminate research findings to complement the traditional scholarly communication model. The use of IRs is beneficial to authors, host institutions, libraries and society at large. Despite the numerous benefits of IRs, there is low deposit of scholarly works by lecturers and the investment on IRs seems to be a waste. This study examined determinants of perceived ease of use (PEOU) of IRs by lecturers in Nigerian universities. A survey of lecturers received 857 respondents. Awareness, anchor and adjustment factors were found to be determinants of PEOU of Institutional repositories by lecturers in Nigerian Universities.  相似文献   

Rethinking the intention to behavior link in information technology use: Critical review and research directions     

《International Journal of Information Management》2021

Extant research on technology acceptance has devoted considerable attention to the relationship between behavioral intention (BI) and system use (SU) over time. However, the empirical results have been mixed—studies have found BI to both influence and not influence SU. Studies that examined the BI→SU relationship have employed different research models and research designs. Prior research models have examined direct effects on SU, indirect effects on SU through BI, the moderator effects on BI→SU, and the mediating role of BI in BI→SU. Studies have employed different types of respondents, information technologies, geographic regions, voluntariness, and measurement designs. This study proposes that such differences in research models and designs contribute to the mixed results for BI→SU, and reports a meta-analysis of findings reported in 113 prior studies along with a critical review of the BI→SU relationship. While no significant differences were found in the results for the BI→SU relationship across various research design characteristics, this study finds that the measurement of SU has been conflated with future and current or past behavior, direct and indirect effects on SU impact BI→SU, BI is modeled to fully and partially mediate the effects of other variables on SU, and moderators for the BI→SU relationship may be necessary. This study identifies several directions for future research and underlines the need to rethink the link between BI and SU.  相似文献
