扬雄《蜀都赋》未入《文选》探赜

《蜀都赋》是扬雄的重要作品之一，其影响广泛而深刻，但萧统等人编录《文选》时将之排除在外。究其原因，其间有萧统的诸种考虑，因为与《文选》中京都赋类的其他作品相比，《蜀都赋》不具备写实性、讽谏性和正统性的特点，而且与《文选》的整体结构也不相符。另外，《文选》的编选者力求精选最能代表梁前文人创作风格的作品。因此，《蜀都赋》最终没能出现在《文选》当中。《蜀都赋》在成文后可能一直以单篇的形式流传，最终被收录在《古文苑》之中。     

论中国特色社会主义制度的本质特征

中国特色社会主义制度具有相对的稳定性、较强的持续性，是中国道路的固态化呈现、中国理论的制度化表达、中国文化的正式化沉淀，因而成为辨识中国特色社会主义最直接的标志和最鲜明的特征。中国特色社会主义制度的本质特征主要体现在以下四个方面：一是在方向层面以中国共产党为“中轴结构”实现对一切工作的有效领导；二是在立场层面坚持以人民为中心的价值取向；三是在方略层面坚持守正与创新的有机统一；四是结构层次层面的延展性。全面把握中国特色社会主义制度的本质特征，对于深入理解中国特色社会主义的内在结构、社会主义国家制度的本质以及人类制度文明的新发展具有重要的意义。     

Estimation of Sobol's sensitivity indices under generalized linear models

We derive explicit formulas for Sobol's sensitivity indices (SSIs) under the generalized linear models (GLMs) with independent or multivariate normal inputs. We argue that the main-effect SSIs provide a powerful tool for variable selection under GLMs with identity links under polynomial regressions. We also show via examples that the SSI-based variable selection results are similar to the ones obtained by the random forest algorithm but without the computational burden of data permutation. Finally, applying our results to the problem of gene network discovery, we identify through the SSI analysis of a public microarray dataset several novel higher-order gene–gene interactions missed out by the more standard inference methods. The relevant functions for SSI analysis derived here under GLMs with identity, log, and logit links are implemented and made available in the R package Sobol sensitivity.     

Inclusion and exclusion in the digital economy: disability and mental health as a live streamer on Twitch.tv

ABSTRACT

In this paper I explore economic and inclusion opportunities for people with disabilities and mental health issues afforded by ‘live streaming’ ? the live broadcast of one’s activities over the internet to a globally dispersed audience. In both 2016 and 2017, the leading live streaming platform Twitch.tv broadcast over 500,000 years of video, which were produced by over two million regular broadcasters (‘streamers’), and consumed by an audience of several hundred million viewers. Streamers can profit, up to and including a full-time living ‘wage’ for those at the highest levels. Numerous successful streamers with chronic health issues have discussed the personal and professional benefits streaming brings them. Utilising data from a research project with 100 interviews, alongside approximately 500 hours of ethnographic observation, this paper examines the experiences of live streaming for broadcasters with disabilities, mental health issues, or physical health issues. Firstly, I explore the positive elements of streaming for these broadcasters, focusing on the many conditions represented in this demographic, and the benefits streaming gives for inclusion and community. Secondly, I consider the negative experiences of these streamers, focused on entanglements of health and technology that make their streaming lives potentially more challenging than their colleagues. Thirdly, I focus on the economic opportunities, and the potential for entrepreneurial activity, the platform affords. I conclude the analysis by exploring how these aspects make live streaming a potentially exemplary emancipatory and entrepreneurial space for these individuals, but not one without challenges.     

Risky choices and emotion-based learning

The paper offers a comprehensive analysis of causes and consequences of the accumulation of emotional experience, measured via skin conductance response, when taking risky choices. A large experimental data set was obtained from a psycho-physiological task conducted with 645 bank customers and financial professionals. With respect to causes, we found that the individual emotional response to gains/losses is trend-dependent and influenced by habituation, as well as by anchoring/framing due to the external layout of risky alternatives. With respect to consequences, we found evidence that the somatic reinforcement experience is able to guide asset picking, but within a long-term strategy. Consequently, selection behaviors were observed in a portfolio mean–variance framework, revealing that somatic markers lead individuals to pursue a long-term ‘psycho-economic’ efficiency that integrates factual information (monetary outcomes) with the implicit subjective experience.     

论孟子仁学的内涵和实质

本文以“爱人”为核心,从亲亲、爱人、爱物三个方面,比较全面地分析和探讨了孟子仁学思想的基本内涵,认为为仁需经过亲亲而爱人,由爱人而爱物的步骤来完成,揭示了一个比较完整的仁学系统,从而把儒家学说核心范畴和最高道德理想的仁,以一种平实简易的样态呈现于世人,人们只要扩充“仁之端”,拓展“亲亲”之情,“盈科而后进”,则可以成为仁人。     

粮食种植户生产环节外包选择行为分析

在构建粮食种植户生产环节外包选择行为理论框架的基础上,运用河南和山西两省小麦主产区2015年631户小麦种植户的第一手调查数据,采用Ivprobit模型分析验证资本密集环节和劳动密集环节的外包行为影响因素,以及资本要素与劳动要素的内部影响关系。研究得出：粮食种植仍以小规模农户为主。资本密集环节外包的比例较高,尤其是机械替代性较强的耕地、播种和收割环节。劳动密集环节外包的比例较低。资本要素对粮食生产的纵向分工和规模化种植有重要的影响。劳动要素对种植户劳动力的非农转移和种植业的兼业化生产具有重要的影响。依据研究结论提出以下建议：鼓励农业社会化服务体系的建设,满足多种农业生产主体的不同需求。鼓励外包服务主体对烘干设施的购置,建设有效外包服务的供需市场。鼓励劳动力从农业向非农业的转移,同时提高专业种植户的农业生产技能。     

欠发达地区农业转移人口市民化现状调查及路径选择研究——基于重庆涪陵的个案分析

通过涪陵的个案分析,发现:西部欠发达地区农业转移人口仍以沿海就业为主,但本土就业、本地就业的比例逐年上升;转移人口返乡流趋势明显,新一代农业转移人口表现出较为明显的本土落户、就近落户意愿,但过高的房价、就业困难与不稳定、教育资源不合理及各类入学限制、社会保障机制不完善、随迁父母不愿意舍弃乡土等制约了意愿的达成.基于此,欠发达地区应该统筹推进就地城镇化、就近市民化、产业集群化、农业现代化,化解欠发达地区农业转移人口市民化困局.

共建共享理念下增强人民获得感的路径研究

以共建共享理念引领人民增强获得感有助于增进人民福祉,维护国家长治久安,增强共产党执政权威。获得感的提出对 于我国特色社会主义建设具有重要的时代价值,但我国人民获得感目前存在物质基础尚不牢固、获得感的分配结构尚待完善、 获得感的精神建设亟需加强等问题。在共建共享理念的引领下,要构建服务型政府,为人民增强获得感提供机制保障;要推进 民生普惠,作为人民增强获得感的决胜要素;要促进基层治理能力现代化,完善人民增强获得感的网格网络;要推动公共产品 供给,打通人民获得感的“最后一公里”。
