新世纪以来,国家出台了一系列强农惠农政策,农业发展取得了巨大成就.粮食产量“十一连增”、农民增收“十一连快”,农业现代化进程加速,城乡公共服务全面发展.但随着我国经济步入新常态,农业面临着“丰年缺粮”呈刚性态势,国内外价格倒挂局面难以扭转,波动性风险和结构性矛盾日益凸显,财政支农政策过于分散,政策着力点与农民收入结构不协调等诸多新的挑战.为此,农村基本经营制度、农产品价格政策、财政支农政策、农业科技政策、农村金融政策等主要农业政策亟待转型升级.在“农业新常态”尚未全面到来之时,中国农业应加快“转方式、调结构”的步伐,主动适应经济新常态.  相似文献   

The role of metacognitive competences in the development of school achievement among gifted adolescents     

Catharina Tibken  Tobias Richter  Nicole von der Linden  Sandra Schmiedeler  Wolfgang Schneider 《Child development》2022,93(1):117-133

Gifted underachievers perform worse in school than would be expected based on their high intelligence. Possible causes for underachievement are low motivational dispositions (need for cognition) and metacognitive competences. This study tested the interplay of these variables longitudinally with gifted and non-gifted students from Germany (N = 341, 137 females) in Grades 6 (M = 12.02 years at t1) and 8 (M = 14.07 years). Declarative and procedural metacognitive competences were assessed in the domain of reading comprehension. Path analyses showed incremental effects of procedural metacognition over and above intelligence on the development of school achievement in gifted students (β = .139). Moreover, declarative metacognition and need for cognition interactively predicted procedural metacognition (β = .169), which mediated their effect on school achievement.  相似文献

Exploring the experiences and responses of LGBTQ+ adolescents to school-based sexuality education     

Shereen C. Naser  Katherine Clonan-Roy  Kimberly A. Fuller  Elizabeth A. Goncy  Nicole Wolf 《Psychology in the schools》2022,59(1):34-50

The purpose of this study is to describe the experiences of lesbian, gay, bisexual, transgender, questioning, intersex, two spirit, and queer (LGBTQ+) youth with school-based sexuality education (SBSE), as well as to document strategies LGBTQ+ youth are using to address their evolving and specific sexual health needs outside of SBSE. Researchers conducted focus groups with 17 adolescents (ages 14–18) from urban and suburban Midwestern cities. Results of this study indicate LGBTQ+ youth find SBSE to be heteronormative, cisgender focused, and primarily focused on pregnancy and disease prevention, which contributes to LGBTQ+ youth experiences of exclusion. In response to SBSE that did not meet student needs, participants reported seeking sexual health information outside of SBSE. Other sources included family and other trusted adults, the Internet, and community resource centers. Students reported variable rates of use and trustworthiness across these resources. Results of this study suggest that school personnel should consider alternatives to traditional SBSE models to meet the needs of LGBTQ+ youth, and that an important part of SBSE should include guidelines for Internet safety.  相似文献   

Universal and Specific Services for University Students with Specific Learning Disabilities: The Relation to Study Approach,Academic Achievement,and Satisfaction

In recent years, an increasing number of students with specific learning disabilities (SLDs) have enrolled in universities. The present exploratory study examined the frequency of use and appreciation of universal (open to every student) and specific services (offered to students with SLDs) and their relation to age, academic achievement, satisfaction, self-efficacy, and use of self-regulated learning (SRL) strategies. Participants were 147 Italian university students with SLD diagnoses (42 males; mean age: 22.49, SD = 3.29). Results showed that, overall, the frequency of use and appreciation of specific services were positively related to academic satisfaction, self-efficacy, and SRL strategies. Furthermore, frequency of use of compensatory tools and dispensatory measures was positively associated with academic achievement. These findings suggest that universities play an important role in supporting students with SLDs during their academic years by providing them with useful services and accommodations.  相似文献   

Physiological reactivity to fear moderates the relation between parenting distress with conduct and prosocial behaviors     

Kostas A. Fanti  Katerina Konikkou  Giorgos Georgiou  Maria Petridou  Chara Demetriou  Georgia Soursou  Melina Nicole Kyranides 《Child development》2023,94(2):363-379

This study investigated whether the associations between parental distress with conduct problems (CPs) and prosocial behaviors (PBs) are moderated by children's skin conductance (SC) and heart rate (HR) reactivity to fear. Participants were 147 Greek-Cypriot children (M_age = 7.30, 44.2% girls), selected from a larger screening sample (data were collected from 2015 to 2018). Longitudinal associations suggested that children with high HR reactivity to fear were more likely to display PB, whereas those with low SC reactivity were more likely to engage in CP behaviors. In contrast, interaction effects suggested that children high on SC reactivity to fear were more susceptible to the effects of parental distress, as indicated by their higher vulnerability to engage in CP (cross-sectionally) behaviors and their lower scores on PB (cross-sectionally and longitudinally).  相似文献   

Amplifying organisational discourses to the public: Media narratives of Teach For Australia, 2008–2020     

Stefanie Sze Wing Chan  Matthew A. M. Thomas  Nicole Mockler 《British Educational Research Journal》2023,49(2):231-247

Alternative teacher education programmes have emerged in many countries as a new approach to recruiting, educating and placing teachers in underperforming schools. The media plays an important role in framing perceptions of these programmes and their teachers, including in Australia, but this has not been the subject of significant research to date. This study examines how one alternative teacher education programme—Teach For Australia (TFAus)—has been positioned and framed within the news media since its inception. It critically analyses the portrayal of TFAus and concomitant educational discourses to explore their connection to larger issues surrounding teacher education and teaching quality. Drawing on an analysis of 122 print/online media articles, we identify narratives related to prestige, benevolence and the ‘alternative’ nature of the programme, alongside a narrative critical of TFAus. Despite this critical narrative, in investigating and opening up a dialogue on the perceptions and depictions of TFAus, we posit that the programme—although controversial in nature—has generally benefited from print media coverage, advancing its reputation as a major contributor to education reform and champion of educational equity.  相似文献

基于检错码静默补偿的跨层链路复激活算法     

孔邵颖  郭宏亮 《科技通报》2014,(12)

有效的链路层的复激活算法可以提高语义系统的检错性能。传统方法采用自适应模式匹配方法实现语义系统的跨层链路复激活,当检错码冗余数据块随机放置时,不能有效实现语义检错。提出一种基于检错码静默补偿的跨层链路复激活算法,构建语义系统网络控制模型,设计检错码编码数据块放置方法,提出检错码静默补偿机制并实现跨层链路复激活算法改进。实验结果表明,采用该算法能有效实现语义系统检错码跨层链路激活,谱峰复激活搜索明显,任务执行精度提高17%,算法在语义网通信编码设计等领域具有较好的应用价值。  相似文献
