播音主持艺术专业实践教学模式探究

分析了目前播音主持艺术专业实践教学的现状,阐述了实践教学改革的重要性,揭示了其中存在问题,针对性地提出了“亦师亦傅、亦生亦徒双重角色”的实践教学模式。这种新的实践教学模式,有利于培养理论知识和专业技能兼备的播音主持人才,亦能够为高校应用型本科艺术类及其他专业人才培养提供借鉴。     

被救助者失信行为的法律规制——以打破“救人反被诬陷”怪圈为中心

良好的人际关系和必要的信任心理既是社会运转的必然要求,更是构建和谐社会的核心内容。"救人反被诬陷"让人心寒,只会导致见死不救不断出现,并造成整个社会人际关系更加冷漠。打破"救人反被诬陷"的怪圈,不能一味责怪人心凉薄,也不能单纯诉诸道德感召。立法对被救助者失信行为的惩罚不力和司法对救助个案判决的失准是被救助者失信的重要原因。因此,应从立法和司法层面堵塞漏洞,通过立法加大对诬陷者的惩罚以矫正被救助者的失信行为,法院审理救助案件时应严格遵守举证规则,实现对救助者不被诬陷的权益保障,以营造一个有利于鼓励危难救助的安全社会环境。     

从费孝通的双轨政治理论看我国社会管理的困境

费孝通的双轨政治理论认为：“一个健全的、能持久的政治必须是上通下达,来往自如的双轨形式。”结合费孝通的观点可以发现：由于缺乏对基层自治组织在民主政治与自我管理层面重要性的深入认识,导致我国社会组织极不发达,公民社会发育缓慢,从而加剧了政府的社会管理压力。要改善当前我国的社会管理困境,必须重视和发挥以基层自治组织为代表的社会组织的功能与作用,从中国的传统政治文化中吸取智慧,构建具有中国特色的公民社会,实现社会的良好管理与和谐发展。     

王国维“通人之学”与“专人之学”的尺短寸长

王国维“通人之学”“专人之学”等学术思想是中国学术研究转型的重大创新,通过对王国维学术成长的梳理、学术成果的分析、学术思想的论证,对“静安之学”进行了全面系统的研究。研究认为,王国维凭借厚实的知识贮备,批判地继承西方哲学理论与中国古代哲学思想,在构建中国大文科的学科体系、研究文史哲的学术体系和中国学者的学术话语体系方面做出了全面系统实践,取得重大进展和开创性成果,堪称开一代风气的大学者;王国维以创辟胜解、通方知类的学术思辨,创立二重证据方法,探索出一条由“通人之学”到“专人之学”学问研究蹊径。系统审读、反思静安之学,对我们严肃读书风气、匡正学问研究态度、提倡学术争鸣、甄别解决知识产权争端、清除学术造假现象、规范学术研究流程,能够起到见贤思齐、弃旧图新之作用。     

An algorithm for the minimum sum of weighted absolute errors regression

We propose an algorithm to estimate the unknown constants in a multiple linear regression model under the minimum sum of weighted absolute errors (MSWAE). The proposed algorithm, a generalization of an earlier algorithm, is compared to a bounded variable algorithm. Some somputational experience is reported.     

双重规训：平台可见性与读者赋权——网络文学平台签约作者的数字劳动研究

以J网络文学平台为研究对象,采用参与式观察与半结构化访谈的研究方法,基于马克思劳动过程理论分析范式,揭示出网络文学平台签约作者的数据劳动实践。研究发现,平台作为技术中介与制度中介,塑造了网络文学领域参与者的表现,策划了签约作者创作作品的可见性,这种可见性由可计量的数据指标构成,对劳动主体进行着隐蔽规制。此外,读者在消费赋权下拥有了参与文化产品生产的主动权,形塑了作者的劳动策略,需要作者投入感情以维系与读者的亲密关系。因此,签约作者在劳动实践的过程中看似具有高度自主性,实则受到了网络文学平台和读者的双重规训。     

Extending dual multiple factor analysis to categorical tables

This paper describes a proposal for the extension of the dual multiple factor analysis (DMFA) method developed by Lê and Pagès 15 to the analysis of categorical tables in which the same set of variables is measured on different sets of individuals. The extension of DMFA is based on the transformation of categorical variables into properly weighted indicator variables, in a way analogous to that used in the multiple factor analysis of categorical variables. The DMFA of categorical variables enables visual comparison of the association structures between categories over the sample as a whole and in the various subsamples (sets of individuals). For each category, DMFA allows us to obtain its global (considering all the individuals) and partial (considering each set of individuals) coordinates in a factor space. This visual analysis allows us to compare the set of individuals to identify their similarities and differences. The suitability of the technique is illustrated through two applications: one using simulated data for two groups of individuals with very different association structures and the other using real data from a voting intention survey in which some respondents were interviewed by telephone and others face to face. The results indicate that the two data collection methods, while similar, are not entirely equivalent.     

双循环发展的改革开放空间试验场——我国开发区的缘起、演进和趋势

开发区是我国改革开放进程中重要的"制度安排",在制度转型、市场机制培育、产业结构升级和带动地区经济增长等方面发挥着引领示范作用,但同时也存在政策效应边际递减、土地资源浪费、创新不足等诸多问题.梳理我国开发区过去三十多年的发展经验和不足,并展望其未来定位是一项重要的研究课题.在详细讨论我国开发区的缘起、动力机制、发展阶段、功能演变、面临问题的基础上,文章从制度安排、比较优势、产业集聚和商业环境四个方面总结了我国开发区取得的成功经验.未来,开发区的发展应实现从生产到生活、从效率到公平、从地的繁荣到人的繁荣、从外围到中心、从专业化到多样化、从高速增长到高质量发展、从对外开放到国内国际双循环等方面的转变.     

Are dual and single exposures differently associated with clinical levels of trauma symptoms? Examining physical abuse and witnessing intimate partner violence among young children

A significant portion of children living in the United States have experienced trauma. Informed by the developmental traumatology model, we explored the effects of physical abuse and witnessing intimate partner violence (IPV) on childhood trauma symptoms. This study utilizes a convenience sample of 580 high‐risk children between 3 and 12 years who received services from one‐child advocacy centre during a 12‐month period. We performed a series of binary logistic regression analyses to examine if physical abuse, exposure to IPV, and dual exposure (i.e., both physical abuse and IPV) are distinctly associated with six trauma symptoms, including anxiety, depression, posttraumatic stress (PTS), dissociation, anger, and sexual concerns. The results indicated that dual exposure was predictive of all trauma symptoms, except for dissociation. Additionally, physical abuse was associated with PTS, anger, and sexual concerns, whereas exposure to IPV was associated with depression, PTS, and sexual concerns. Research and implications for practitioners working with young children are discussed.     

大数据背景下个人信息处理行为的法律规制——以个人信息处理行为的双重外部性为分析视角

大数据背景下个人信息处理行为既引发数据安全风险等负外部性，也会带来分享经济价值实现等正外部性，"大数据悖论"现象揭示了双重外部性成因。基于"外部性内在化"原理赋予信息主体以个人信息权并赋予数据控制者以大数据财产权虽有助分别规制其双重外部性，但网络大数据背景下其双重外部性规制彼此交互影响而面临两难困境。法经济学关于"损害之相互性"理论证立了基于"风险导向理念"规制个人信息处理以破解其两难困境的经济逻辑。大数据产业发展有赖个人信息处理的"外部性外部化"而实现分享经济。法经济学关于"公地喜剧"理论证立了基于"外部性外部化"规制个人信息处理而满足大数据产业发展需要的经济逻辑。大数据背景下个人信息处理的规制有赖从"压制型法"到兼及"回应型法"的理念转换，从"外部性内在化"兼及"外部性外部化"的机制并举，从数据资源权利配置兼及数字技术权力干预的措施协同，实现大数据产业创新与个人信息安全的有机平衡。
