Piece-by-Piece Review of Digitize-and-Lend Projects through the Lens of Copyright and Fair Use     

Michelle M. Wu 《Legal Reference Services Quarterly》2017,36(2):51-73

Digitize-and-lend library projects can benefit societies in multiple ways, from providing information to people in remote areas or with physical disabilities to facilitating the sharing of library resources with information-poor communities. This article explores the potential of digitize and lend as well as outlines how projects can be undertaken in a manner respectful of the balance of copyright.  相似文献   

“Enactment of Sámi Past in School Textbooks: Towards Multiple Pasts for Future Making”     

Torun Granstrøm Ekeland 《Scandinavian Journal of Educational Research》2017,61(3):319-332

The article examines the use of archaeological knowledge in elementary history textbooks used in Norwegian schools today. The aim is to determine whether we can find any traces of colonialism by reviewing how these narratives perform in interrelations within and between the Sámi and Norse pasts, and how the narratives allow for hybridity and heterogeneity. Postcolonial theory turns the narrative into an object of analysis. The findings show that the Sámi material remains are outside the system of cultural change and that the temporal and spatial distances produce binary and homogeneous cultures. New material perspectives can intervene in singular performativity. Learning to enact dynamic material heterogeneity may affect the future of pupils’ participation in cultural negotiations of pastsin present.  相似文献   

Family factors and parenting in Ukraine     

《Child abuse & neglect》2017

The present study aimed to estimate the use of positive and negative parenting practices in Ukraine and explore relationships between parenting practices, intimate partner violence (IPV), alcohol use, and sociodemographics. Parents of children (N = 320) ages 9–16 from three Ukrainian regions answered questions from the Alabama Parenting Questionnaire (APQ), the Revised Conflict Tactics Scales (CTS-R), Family Adaptability and Cohesion Evaluation Scale (FACES), and the Alcohol Use Section of the Drinking and Drug History and Current Use Patterns questionnaire. Ukrainian parents who reported lower use of alcohol, balanced family functioning and lower intimate partner violence were more likely to use positive parenting and less likely to use negative parenting practices. Parents with lower education were more likely to use negative parenting practices. Furthermore, alcohol use, IPV, parent education and higher family income were significantly and indirectly related with positive and negative parenting scores. The model explained 61% of variance in the positive parenting, 67% in the negative parenting.  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   

Childhood adversity and the risk of substance use and delinquency: The role of protective adult relationships     

《Child abuse & neglect》2017

Youth involved in the child welfare system experience multiple early adversities that can contribute to increased risk of substance use and delinquency. Although adverse childhood experiences (ACEs) have been associated with poorer behavioral outcomes among youth, less is known about the possible protective factors that may influence the relationship between early adversity and risk-taking behavior. This study examined whether protective adult relationships moderated the link between cumulative ACEs and substance use and delinquency after controlling for demographic characteristics in child welfare-involved youth. The sample included 1054 youth, ages 11–17, from the National Survey of Child and Adolescent Well-Being II who were in the first wave of data collection. Results showed that protective adult relationships moderated the relationship between ACEs and substance use, but not for delinquency. Specifically, under lower levels of protective adult relationships, cumulative ACEs related to increased substance use among youth. Implications for child welfare practices to target youths' support systems are discussed.  相似文献   

Teachers' perspectives of changes in their practice during a technology in mathematics education research project     

《Teaching and Teacher Education》2017

Teachers' perception of changes to their teaching practice, with respect to digital technology use in secondary school mathematics, during their participation in a research project are reported. Two case studies are presented of teacher perspectives illustrative of the range of perceived changes teachers made to their practice and positions along the ‘path of change’ during their participation in the project. Participating in a project supportive of teacher change and resulting in perception of substantial change was necessary, but not sufficient, to meet the goal of transformative use of digital technologies to increase the level of cognitive demand experienced by students.  相似文献   

黄淮海地区产业与用地空间集聚发展战略模式探讨   总被引：1，自引：0，他引：1  

曹志宏  郝晋珉  郭力娜  高红梅 《资源科学》2010,32(11):2145-2151

本文利用基尼系数方法研究黄淮海地区经济发展要素与产出的空间集聚状况,并依据不均衡发展理论构建其产业与用地空间集聚发展战略模式。研究结果表明,相对黄淮海地区产业发展经济投入和产出而言,该地区人口和建设用地的空间分布则表现出比较分散性;由于土地具有固定性和基础承载属性,土地空间配置的分散性必然导致其它生产要素不能按照最优方式进行配置,进而导致区域产业发展的低效性。鉴于国外发展经验和黄淮海地区经济发展的实际需要,该区域非农经济建设进入大力发展大都市圈与都市带相结合的网状聚集发展阶段。依据点轴发展理论及黄淮海地区各市非农社会经济建设竞争力和主要交通状况分析,区域非农产业和用地在空间上呈现出"两横三纵四心"集聚发展模式,其它地区为农业生产和农地生态保护集聚发展区。本文构建黄淮海地区农业和非农产业空间集聚发展战略模式的实质就是为了加强区域内部地区间农业生产和非农经济建设的分工与协作,这样不仅有利于优化区域土地利用布局,提高土地利用效率和区域经济发展的市场综合竞争能力,而且还有助于减少经济建设对农业生产的不良影响和缓解当前土地供求矛盾。  相似文献   

关于深化国有资源有偿使用制度改革的理论初探     

武心英 《连云港职业技术学院学报》2007,20(2):43-45

在粗放型的经济增长方式下，由于我们过多地运用了行政手段来管理经济，管理国有自然资源，导致国有自然资源一直是无偿或低廉使用的。随着我国经济增长方式的根本性转变，国有资产无偿使用制度的弊端已显现，一是导致国有自然资源的收益大量流失；二是导致国有资源配置无序和扭曲。因此，深化国有资源的有偿使用制度改革，对于维护国有资源的权益，加强资源开发者的经济责任，实现资源的最优配置，加速与国际通行做法的并轨，具有极为重要的现实意义，有广为实行之必要。  相似文献
