人类命运共同体构想的三维审思：逻辑起点·现实基点·思想源点

人类命运共同体构想作为马克思主义中国化的最新理论成果，是在积极反思人类生存现状的基础之上，对世界未来发展形态的一种前瞻性擘画。总体观之，作为“类”存在的人的主体自觉以及马克思主义“类”思想是人类命运共同体构想的逻辑基点， 现代“人类交往”方式的演进与普遍发展是人类命运共同体构想的现实基点，中国传统文化中的“和合”理念是人类命运共同体构想的思想源点。逻辑起点、现实基点与思想源点共同构成人类命运共同体构想的生成之源，对其系统、深入的阐释与审思则是我们学习、领悟、实践这一伟大构想的重要环节。     

治理的发轫与嬗变：中国历史视野下的考察

国内学术界一般以西方学术发展史作为背景，把治理作为一种社会互动来进行研究。中国历史视野下的治理，发轫于中国社会生活，其内涵最初主要是为了获取生存资料，即有收成才能够形成秩序也就是治理。从“乂”这个象形文字来看，乂就是治理，其原意为“收割”。不过，围绕生存资料的生产和分配逐渐产生了更加丰富的社会权力关系，而巩固和拓展这种权力关系则使得构筑更加严格的秩序成为必然。神秘感是构筑秩序的重要依据，而赋予仪式以神秘感的则是觋、巫等知识群体，他们将天、帝、王、人通过仪式联系在一起，建构起一套以礼为基础的秩序。但是，西周末年，觋、巫的神秘感被世俗的君权摧毁以后，“君臣秩序”以及由此构筑起来的社会秩序都被颠覆，从而导致“君臣之礼既坏”和“礼坏乐崩”的情形。“以智力相雄长”不仅表现在王室内部、诸侯之间、社会层面上，而且也表现在知识分子身上。从此以后，士绝大多数以追逐爵禄而骄天下为荣，以至于两千多年来一直存在“士贱而君肆”的情形。“君士互动”的治理模式，正是随着神秘主义的礼的崩溃而崩溃的。     

On the power of goodness-of-fit tests for the exponential distribution under progressive Type-II censoring

The aim of this article is to review existing goodness-of-fit tests for the exponential distribution under progressive Type-II censoring and to provide some new ideas and adjustments. In particular, we consider two-parameter exponentially distributed random variables and adapt the proposed test procedures to our scenario if necessary. Then, we compare their power by an extensive simulation study. Furthermore, we propose five new test procedures that provide reasonable alternatives to those already known.     

Some count-based nonparametric tests for circular symmetry of a bivariate distribution

In this paper, we revisit the problem of testing of the hypothesis of circular symmetry of a bivariate distribution. We propose some nonparametric tests based on sector counts. These include tests based on chi-square goodness-of-fit test, the classical likelihood ratio, mean deviation, and the range. The proposed tests are easy to implement and the exact null distributions for small sample sizes of the test statistics are obtained. Two examples with small and large data sets are given to illustrate the application of the tests proposed. For small and moderate sample sizes, the performances of the proposed tests are evaluated using empirical powers (empirical sizes are also reported). Also, we evaluate the performance of these count-based tests with adaptations of several well-known tests such as the Kolmogorov–Smirnov-type tests, tests based on kernel density estimator, and the Wilcoxon-type tests. It is observed that among the count-based tests the likelihood ratio test performs better.     

我国核电技术创新中的政企协调度实证分析

为探究我国核电技术创新中政府和企业的协调情况,文章基于协同学理论和复杂系统理论,从核电技术创新的特点出发,将核电技术创新系统解构为政府子系统和企业子系统,采用2007年—2017年相关数据,运用协调度测度模型对政府子系统有序度、企业子系统有序度和政企协调度进行测度和分析。研究结果显示:我国核电技术创新中政企协调度随时间呈现“N”型变化趋势,且协调度均值较低；政府子系统有序度和企业子系统有序度表现为“双螺旋”协调演进；制约政府子系统有序度和企业子系统有序度提升的关键因素分别为税收优惠力度和企业R&D强度。     

大众传播中的“国家教师”媒介形象分析

运用传播学内容分析法，以中央媒体对获得"全国教书育人楷模"和"最美教师"荣誉称号的"国家教师"相关报道为研究对象，从外在和内在两个方面对大众传播的"国家教师"媒介形象进行分析。外在形象包括教师性别、年龄、教龄、外表、场景以及任教的学校类别、区域、学科专业等方面，内在形象包括职业精神、职业知识和职业能力等方面。研究发现，大众媒体对"国家教师"形象的刻画和宣传符合社会公众认知教师职业的基本逻辑，起到了传递教师精神、端正教师形象、唤起社会尊重教师的功效，但也存在城乡教师形象传播刻板化以及教师普通人形象展现不充分等问题，可在后续的传播中对"国家教师"形象的价值倾向进行适当调整。     

Challenges and dilemmas working with high‐conflict families in child protection casework

Social workers within child protection services report that families marked by high levels of conflict between separated parents are among the most challenging cases to handle. Few studies however have focussed on how social workers themselves experience and meet with parents involved in hostile martial interactions. This article reports on a qualitative study involving 31 social workers and provides an analysis of their experiences and dilemmas in working with such families. Findings demonstrate that social workers struggle to find ways to help high‐conflict families and often find themselves at an impasse. Parents involved in such conflict are highly resistant to change, and social workers struggle to engage with them over concerns about their children. Furthermore, findings suggest that social workers lack organizationally allotted time to assist the parents. I conclude by discussing ways in which emotional support, empowering interventions, and strength‐based approaches enable social workers to manage relationships with high‐conflict families. More research on this topic is needed to support and promote better practices for social workers to be more effective in assisting high‐conflict families.     

“游戏成瘾”与健康性应对——兼论健康传播在游戏中的适应性

《国际疾病分类》正式将"游戏成瘾"收录其中，在强调成瘾危害的同时，也认可其作为社会问题医学化的某种待研究领域。实际上，"游戏成瘾"已经构成了现代意义上的"疾病"认知，在与健康传播的缠绕之中既形成了独特的研究范式，也面临着自身困境。立足于此，应从游戏量级、游戏内容、游戏情境及游戏关联等方面进行相关的健康应对，并在健康支出、文本、体验及情感等传播变量中予以规制及改善。同时，以游戏"情商加油站"为个案，探讨健康传播作为一种研究视角，在游戏适应中的严肃化转向及可行性。
