区域农户农地流转行为对土地利用变化的影响   总被引：6，自引：1，他引：6  

张丽君  黄贤金  钟太洋  钟太洋  方鹏 《资源科学》2005,27(6):40-45

本文首先在理论上阐述了区域土地市场发育以及农户土地流转行为与土地利用变化之间的相互关系:在市场比较收益、农产品贸易和政府决策等因素的调控作用下,农村农地流转行为很大程度上改变了农村土地利用结构、利用方式以及利用强度.为进一步从农户层次上以及微观经济机制尺度上揭示农地市场对土地利用变化的影响程度,论文以泰州市兴化市的村庄及农户问卷调查数据为依据,建立了农户农地流转与土地利用变化之间的计量模型.模型运行的结果表明:农户拥有农地总面积、农地流转率、农产品销售率、粮食作物产值以及农业中非粮食作物产值等因素对农村土地利用变化有显著的影响;农地流转在很大程度上导致了土地利用类型的变化.最后,论文结合模型的分析结果提出了适度规模经营,调整农业产业结构,推进农产品市场贸易,规范政府行为以及改进农地流转机制等五方面的政策建议.  相似文献   

1990～2012年北部湾经济区土地利用程度变化分析     

黄春芳  马文东  李鸿儒  莫正斌 《大众科技》2016,(7):38-40

通过对1990～2012年北部湾经济区土地利用结构的变化分析,运用土地利用程度指数模型以及土地利用程度变化模型统计了各地区土地利用程度的时空变化特征及其区域差异。结果表明,1990～2012年北部湾经济区土地利用程度大幅度提升,增加了43.22个百分点,但土地利用程度分布格局并未发生太大变化;土地利用程度变化量及其变化率均大于0,土地利用处于发展期;在自然条件的限制下,区域内部土地利用程度差异较大。  相似文献   

Identifying families with complex needs after an initial child abuse investigation: A comparison of demographics and needs related to domestic violence,mental health,and substance use     

《Child abuse & neglect》2017

Families with complex needs related to domestic violence, mental health, and substance use have some of the worst child protective services (CPS) outcomes. Although many of these families are identified during a CPS investigation and subsequently referred to home-based postinvestigation services (HBPS), many are re-reported to CPS, so it is important to understand the postinvestigation experiences of this vulnerable group. Therefore, this study compared families with and without complex needs to understand their uniquedemographics, needs, and postinvestigation outcomes.The sample consisted of 2008 caregivers who received HBPS following an initial CPS investigation. The Family Assessment Form (FAF) was used to measure family functioning in eight domains using a 1–5 scale with higher ratings representing worse functioning. Complex needs were indicated by a mean FAF score of 3 or higher for either domestic violence, mental health, or substance use. Using Pearson chi-square analyses and two-sample t-tests, comparisons were made between families with (n = 836) and without (n = 1172) complex needs. Half of caregivers with complex needs had a history of abuse, 25% had three to five needs, and nearly half had six to eight needs; 90% of caregivers without complex needs had zero to two needs. Furthermore, caregivers with complex needs had higher mean scores for concrete, educational, and clinical needs. These findings highlight the importance of recognizing variation among families referred to HBPS and accurate screening to ensure that families with complex needs are offered and receive services matched to their unique characteristics and needs.  相似文献   

Time spent on the Internet by multicultural adolescents in Korea     

Yangmi Lim 《Asia Pacific Journal of Education》2017,37(1):55-68

This study analysed The 8th Online Survey of Adolescent Health and Behaviour in 2012, which is a government-approved statistical survey of Internet use and patterns in Korea. We conducted a propensity score matching (PSM) to control for economic status differences between monocultural and multicultural families and an ANOVA to estimate the effects of multicultural family status, adolescents’ gender, school grades, locality, and parents’ academic background on adolescents’ Internet use (for studying and entertainment). The study revealed the following: with regard to Internet use patterns, adolescents from both monocultural and multicultural families selected gaming as their first choice, followed by studying and data searching. Furthermore, main and interaction effects of independent variables on adolescents’ time spent on the Internet for studying were not significant. However, the interaction effects of multicultural family status and mothers’ academic background on adolescents’ time spent on the Internet for entertainment were statistically significant. Specifically, adolescents’ time spent on the Internet for entertainment was higher in multicultural families with mothers whose education level was lower than middle school. Finally, we suggested that the government should provide full support to less educated mothers in multicultural families for effectively and constructively controlling their children’s Internet use and teaching it to them.  相似文献   

Personally driven professional development: reflective self-study as a way for teachers to take control of their own professional development     

Karl Attard 《Teacher Development》2017,21(1):40-56

This article is about personally driven professional development through the use of reflective self-study. The argument that teachers need to take responsibility for their own learning while also taking decisions on how and in what areas to develop is strongly made throughout the article. Data for this article were gathered over a 10-year period where the author engaged in several studies using self-study as methodology. Between studies, the author kept using reflective self-study as a professional development tool, and it is these data between various studies that were analysed using thematic and reflective analysis. Such analysis resulted in various overarching themes that show how reflective self-study can be of benefit if used by teachers researching their own classrooms. Benefits include teachers taking full ownership of their learning, relevance of learning, learning that is ongoing and not restricted to specific times and places, taking problematic situations as learning opportunities and how other sources take on new relevance through reflective self-study. Some implications for teacher-education programmes and current school structures are also discussed.  相似文献   

Reading to Learn or Learning to Read? Engaging College Students in Course Readings     

Mary Margaret Kerr  Kristen M. Frese 《College Teaching》2017,65(1):28-31

Despite instructors' belief that class readings are integral to the learning process, only 20–30% of undergraduate students complete required readings. Failure to complete course reading has been associated with declines in exam and research performance. This article first offers a brief review of the literature on why students do not complete course readings: 1) unpreparedness, 2) lack of motivation, 3) time constraints, and 4) an underestimation of reading importance. We then identify approaches that encourage students to read, enjoy reading, and develop metacognitive knowledge, shown to improve learning.  相似文献
