高校是“立德树人”培养高素质人才的基地,始终坚持在党的领导下办好中国特色社会主义高校,需要在思想和行动上执行好“四种形态”。正确认识当前高校践行“四种形态”存在的“精细治理”“文化管理”“经验管束”“粗放管理”等“四级样态”,对于高校党组织更好推进“四种形态”在高校落地生根具有重要意义 相似文献

湖北咨议局是试图推行资产阶级君主立宪政体下的一个省级地方议会的预备机构,却在资产阶级宪政请愿运动中一再受挫,由绝望毅然转向革命,在武昌首义中推波助澜.湖北咨议局立场的转变对于武昌首义成果的巩固与扩大乃至对于辛亥革命在全国的深入发展起到了非常重要的组织和促进作用. 相似文献

Using nationally representative data from the Early Childhood Longitudinal Study-Kindergarten Cohort (N = 21,409; 10,452 girls and 10,957 boys; mean age = 7.24 years), the association between first-grade classroom sex composition (CSC), measured as the percentage of female students, and end of the year academic (reading, mathematics) and socio-emotional (externalizing problems, internalizing problems, self-control, interpersonal skills) outcomes was examined. Using multilevel modeling techniques and controlling for prior achievement levels, CSC was positively associated with children’s reading achievement at the end of first grade; students performed better in reading in classes with a higher percentage of female students. CSC was also associated with three of the socio-emotional outcomes; controlling for prior levels, students in classrooms with a higher percentage of girls had better self-control and interpersonal skills and fewer internalizing problems. Classroom behavior mediated the effects of CSC on reading achievement and the socio-emotional outcomes. Implications for the composition of first-grade classrooms are discussed. 相似文献

构建“四化”发展水平指标体系,基于2006-2013年中国省际面板数据,运用全局主成分分析法得出“四化”发展水平得分,在此基础上,对“四化”耦合发展互动关系进行计量分析.结果显示:“四化”之间存在长期均衡的协整关系;信息化对于农业现代化边际贡献度为0.231 8,弱于工业化的边际贡献;信息化对于城镇化的边际贡献度为0.702 3,强于工业化对城镇化的贡献;信息化对于工业化的边际贡献不显著.基于实证分析结果,提出加强城镇信息化建设和提升城镇化人口素质的政策建议. 相似文献

回顾我国集体林权改革的主要进展,介绍产权四模式的主要观点,提出深化集体林权改革的思考和建议。研究发现,林权改革没有统一的格式,产权四模式总结了发展中国家林权改革的一些规律,可以为我国集体林改所借鉴;与其他模式相比,财产权模式对我国集体林改影响最大,明晰产权、提高效率一直是集体林改的目标;农业结构模式明确提出的市场机制可能带来产权不安全的问题需要引起重视;制度模式主张政府发挥产权改革的主导作用、制定法律法规巩固产权的主张对深化林权改革有重要借鉴意义;共有产权模式提出的保留共有森林资源为贫困人口提供"一席之地"的主张,为减贫和乡村振兴提供思路。在结束明晰产权主体改革任务之后,应将工作重点转向制定相关法律法规巩固产权改革成果、维护农户林权利益;在推动林地规模化经营中,要谨慎推进森林资源金融化,防止出现"代价高昂的不平等";充分认识集体林权改革的复杂性、艰巨性和长期性,将林改工作从工程式运作逐渐转向常规监管,加强林权管理。 相似文献

传统文士在春秋战国崛起时,对道与势的态度经历了由对道的恪守到对势的依附的转轨过程。汉以后,由于儒术的强化、引导、依附权势成为传统文士人格的普遍特征。“二十四友”的附势心态就是这种特征在西晋政治、文化背景下的自然显现。与文学史上其它文士集团相比,“二十四友”的附势心态表现得最为典型。 相似文献

Cohabitation in Great Britain: not for long, but here to stay 总被引:2,自引:1,他引:1
John Ermisch & Marco Francesconi 《Journal of the Royal Statistical Society. Series A, (Statistics in Society)》2000,163(2):153-171
This paper uses a new source of data to study the dramatic increase in cohabiting unions in Great Britain. It analyses, in turn, entry into first partnership, the stability of cohabiting unions and repartnering after dissolution of cohabitation. In excess of 70% of first partnerships are now cohabitations, and these last a relatively short time before being either turned into marriage or dissolved. The shift to cohabitation as the dominant mode of first partnership plays an important role in the delay of first marriage and motherhood. The paper also investigates the factors that are associated with the outcome of cohabitations. 相似文献

ABSTRACTWe introduce a new methodology for estimating the parameters of a two-sided jump model, which aims at decomposing the daily stock return evolution into (unobservable) positive and negative jumps as well as Brownian noise. The parameters of interest are the jump beta coefficients which measure the influence of the market jumps on the stock returns, and are latent components. For this purpose, at first we use the Variance Gamma (VG) distribution which is frequently used in modeling financial time series and leads to the revelation of the hidden market jumps' distributions. Then, our method is based on the central moments of the stock returns for estimating the parameters of the model. It is proved that the proposed method provides always a solution in terms of the jump beta coefficients. We thus achieve a semi-parametric fit to the empirical data. The methodology itself serves as a criterion to test the fit of any sets of parameters to the empirical returns. The analysis is applied to NASDAQ and Google returns during the 2006–2008 period. 相似文献

ObjectivesTo understand the experience of Metro Vancouver’s Homelessness Partnering Strategy-funded Housing First program and how it is functioning from the perspective of a representative sample of providers and clients who deliver and receive HF services.MethodsThirty-four clients and providers who currently or formerly delivered HF in Metro Vancouver participated in one-on-one interviews (n = 26) or focus groups (n = 8) between March and April 2017 and data were thematically analyzed.ResultsStrengths of the HF program included: the ability to transition persons from the street into housing with individualized service supports and, in certain cases, with 12-month rent subsidies, household goods, and connection to community resources. Identified program weaknesses were: eligibility criteria, limited rent subsidy funds, limited provider capacity, and workload burden. Suggested opportunities to improve HF were: streamlining federal and provincial reporting and rent subsidy systems and building friendly landlord networks. Potential threats to HF described were: limited affordable housing, stigma and discrimination toward clients, inadequate income assistance, and limited opportunity for cross-sector collaboration.ConclusionsThe delivery of HF in regions that have limited affordable housing presents unique challenges. Recommendations are provided to improve HF practice and policy in these contexts. 相似文献
