百年中国共产党独特性的解释进路、表现向度与生成逻辑

和其他政党相比较,中国共产党具有不同于一般政党的独特样态,它们集中诠释着党的独特优势和优良品质。党的独特性蕴含在党的历史使命与行动价值之中,同时也通过具体的政党行为映现出来。党的独特性主要表现为具有彻底的自我革命性、博大的人类情怀、超越自我的牺牲精神、高度的政党纯洁性以及非凡的红色政党气质等。党的独特性的生成具有复杂性,是内在与外在因素、历史和时代环境以及国内和国际条件等共同作用的集合体。党的独特性源于无产阶级政党的特殊基因,是对党的百年政治实践的能动反映,是党持续拓展政党功能的集中显现,更是党有效应对百年复杂世界体系的结果。     

人民币多重均衡汇率与经济增长

多重均衡汇率的政策意义在长期内可表述为:政府的汇率政策辅以扩张性货币政策,不仅在短期内可以增加就业和提高经济增长率,并且也将在长期内将宏观经济提升至一个较高的发展轨道。因此,只要通货膨胀的压力在可被承受的范围之内,政策即可以通过选择一个较低的汇率来加速长期的经济增长。     

应用现代教育技术提高教育教学质量

现代教育技术朝着智能化、多媒化、网络化的方向发展,具有教学信息资源和信息渠道多元化、课堂教学开放化、教学手段智能化以及教学过程情景化等特点。而课堂教学现代化是提高教学质量的有效途径,通过合理应用现代教育技术手段,使教学效果达到最优化。     

赫梯国王名字的演变及族群认同构建

赫梯人所建立的赫梯文明及赫梯王国具有多元文化交融和多民族共存的特点,这在赫梯国王名字的历史演变中得以窥见。赫梯国王名字的由来包含了城市名、神灵名、高山名和祖先名等多种来源,而赫梯国王名字的由来及其历史演变同时也反映出国王名字在文化上的多元性,在寓意上的积极性和时代性,以及赫梯人对王权权威性、合法性和王位正统性的追求。赫梯国王名字的演变及其文化特征是赫梯族群认同构建的必然结果。在多民族文化并存的状态下,赫梯人通过文化选择的方式逐渐形成了服务于赫梯王权的族群认同体系,这一体系在赫梯帝国灭亡之后甚至也产生了一定程度的影响。     

符号学视野下体育与少数民族的国家认同构建

体育与少数民族国家认同问题是一个重要的研究课题,学界目前主要就体育现象本身进行对比或论证少数民族国家认同,而缺乏符号学这一简约方法的深层次解读。国家认同是各种象征符号的集合。体育是一种天然的符号,具有丰富的文化象征含义。因而从符号学视野探究体育与少数民族国家认同具有重要的理论与现实意义。少数民族的国家认同核心是政治认同与文化认同,体育的物源符号化、自然寓意、伴随文本意义、元语言解读、共同记忆塑造功能,有力促进现代国家少数民族国家认同。认清体育符号的标出性历史反转趋势,采取适当宽幅的文化选择,加强体育元语言的解读,充分利用体育符号媒介作用,增强少数民族文化自觉与自信、强化中华“多元一体”认识,厘清国家政治边界,从而有力促进少数民族国家认同的构建。     

场域转换与文化反哺:青年群体与变迁社会的信息互动

以布迪厄场域理论来考察不同社会形态下青年与社会的信息互动实践,发现青年与社会的信息互动在具有“位置-权力”关系的场域中展开,“位置-权力”关系通过信息资本的占有而建构。社会形态随技术变革更迭,青年与社会信息互动的场域逻辑与运行机制发生相应转变。从农耕社会到工业社会再到信息社会,青年与社会的互动场域变得多样,并且发生着从家庭向学校再向网络空间的偏向性转换,场域运行的推动力量也从时间权威向结构权威再向认同权威转换。可以说,青年与社会信息互动场域的转换,正是人类在不同社会形态下对“用时间消灭空间”的信息传播时空观的生产实践与社会表征。     

An elastic-net penalized expectile regression with applications

To perform variable selection in expectile regression, we introduce the elastic-net penalty into expectile regression and propose an elastic-net penalized expectile regression (ER-EN) model. We then adopt the semismooth Newton coordinate descent (SNCD) algorithm to solve the proposed ER-EN model in high-dimensional settings. The advantages of ER-EN model are illustrated via extensive Monte Carlo simulations. The numerical results show that the ER-EN model outperforms the elastic-net penalized least squares regression (LSR-EN), the elastic-net penalized Huber regression (HR-EN), the elastic-net penalized quantile regression (QR-EN) and conventional expectile regression (ER) in terms of variable selection and predictive ability, especially for asymmetric distributions. We also apply the ER-EN model to two real-world applications: relative location of CT slices on the axial axis and metabolism of tacrolimus (Tac) drug. Empirical results also demonstrate the superiority of the ER-EN model.     

Outlier detection and robust variable selection via the penalized weighted LAD-LASSO method

This paper studies the outlier detection and robust variable selection problem in the linear regression model. The penalized weighted least absolute deviation (PWLAD) regression estimation method and the adaptive least absolute shrinkage and selection operator (LASSO) are combined to simultaneously achieve outlier detection, and robust variable selection. An iterative algorithm is proposed to solve the proposed optimization problem. Monte Carlo studies are evaluated the finite-sample performance of the proposed methods. The results indicate that the finite sample performance of the proposed methods performs better than that of the existing methods when there are leverage points or outliers in the response variable or explanatory variables. Finally, we apply the proposed methodology to analyze two real datasets.     

Vocational Experiences and Quality of Life of Migrants: Overview and Future Research

Quality of life is a complicated concept that has attracted broad attention from multiple disciplines. This article introduces a set of studies that employ diverse approaches to explore how work, vocational, and career experiences shape quality of life among migrants, and proposes a future agenda to extend this stream of research. Specifically, operationalizing quality of life in different ways, research showcased in this special issue has demonstrated how international and intranational migrants achieve, maintain, and enhance their well-being in different life domains. Reflecting on the literature and the showcased studies, this article proposes that future research should advance the current inquiry by better categorizing vocational experiences, uniquely operationalizing of quality of life in migration contexts, taking a more culturally sensitive perspective, and broadening methodological approaches.     

Supportive organizational environment,work-life enrichment,trust and turnover intention: A national survey of PRSA membership

Based on an online survey of a national random sample of the PRSA membership (n?=?650), this study is among the first to explore public relations employees’ own turnover intention and propose three contributing factors for employers to keep top talent in PR industry: a family-supportive organizational environment; the positive, enriching impact of professional work upon practitioners’ life; and PR practitioners’ trust toward employers. Theoretical and practical implications are discussed.
