Shorter hours wanted? A systematic review of working-time preferences and outcomes

Changes in working time have important economic, social and environmental implications. However, research on workers' preferences is highly fragmented across disciplines and journals. To overcome this, the present article provides a systematic review of the literature, analysing 173 studies. The study shows that working-time outcomes and mismatches are mostly studied in a small group of OECD countries, using survey data and statistical methods. The most clear and consistent results are about gender, care responsibilities and current working hours. Among professions, only the medical workforce receives substantial attention. Norms and preference formation are poorly understood, and more qualitative research is essential to understand how working-time reductions could spread.     

《新唐书》的“四夷传”与唐代的民族史志研究

唐王朝是一个疆域辽阔的统一多民族帝国,唐王朝不但能够很好地处理国内的民族问题,还能够与海外的民族或者民族国家建立友好关系,正是在这样宏大的历史背景之下,《新唐书》以超过以往正史的丰富内容以及庞大的文献体量,记载了所有唐朝直接统治、间接管理的民族,以及唐朝人目光所及的海外民族,以民族史志的方式给我们展示了一幅具有世界意义的民族发展画卷。     

东北亚地区安全态势与中美关系

中日关系和朝鲜半岛局势是当前东北亚地区的两大热点议题。中日关系方面,虽然今年以来中日释放出加强经济合作的信号,两国政治交往的频率和层次也出现回升,但是钓鱼岛争端和日本领导人参拜靖国神社这两个导致中日关系恶化的症结短期内难以化解,特别是在安全领域,两国缺乏互信,摩擦不断。朝鲜半岛局势仍继续陷入“紧张-缓和-紧张”的反复模式,在经历了短暂的缓和后再次趋于紧张。从东北亚地区安全格局看,中美关系构成了这一地区安全与稳定的主轴。因此,梳理中美两国在东北亚安全领域的合作与分歧,进而以此为基础思考中国的应对之策,对维护中国周边稳定具有重要意义。     

良性互动的民族关系是国家稳定和发展的重要基础

民族关系是多民族国家面临的影响其发展稳定的重要社会问题。民族关系主要有封闭排斥型、压迫对抗型、平等包容型、融合型四种形式,这些形式主要体现在经济、政治、文化、社会、生态建设领域。我国目前总体处于平等包容型民族关系发展阶段,但新形势下出现了一些不适应平等包容型民族关系发展的问题,值得关注与深思。只有协调各民族利益关系、建立平等包容互助的民族关系、制定符合规律和实际的处理民族关系的政策,才能促进民族关系良性互动。     

基于能力视觉的《公共关系学》课堂教学模式的改革与实践

课堂教学模式是实现人才培养目标的关键之一。本文立足于课堂教学模式的改革和创新,分析了《公共关系学》传统教学模式存在的弊端,并从教学目标的设计切入,探讨了基于能力视觉的公关课堂教学模式改革的基本思路:强调实施案例教学,着眼能力培养;进行实战策划,强化实际应用;加强模拟演练,提高公关技能等改革措施。     

宋代澉浦镇兴衰轨迹再探

北宋中前期,澉浦镇完成军事性质向经济性质的转变。北宋后期至南宋中前期,其经济功能进一步强化。南宋后期,澉浦镇渐趋衰落,其衰落与鲍郎盐场的分立并无直接关系,而与当时南北政权的政治军事格局转变相关。端平以后,蒙元发动灭宋战争,南北关系趋于紧张,澉浦镇作为临安门户,军事地位凸显,影响其海运事业,遂至衰落。澉浦镇的兴衰转变展现了南宋时代江浙地区通商与海防的矛盾,促使我们去反思江南市镇发展史的“延续性”问题。     

中国出现新乡村性？——基于长江三角洲地区乡村旅游发展的研究

在中国,越来越多城市居民喜欢利用周末及节假日前往乡村地区休闲度假,给旅游地理学和休闲地理学研究带来了新的研究方向,为研究中国新型的甚至是未知的城乡关系提供了新的视角。这种新的休闲度假趋势主要产生于大中型城市周边的乡村地区。以位于长江三角洲的上海周边郊区为例,研究新型乡村旅游在城郊地区的发展,在保留和修缮传统乡村景观的同时,也产生出新型景观。旅游的发展促使乡村地区结构重组,建立了乡村旅游从业者的经营活动与当地农业发展之间的新联系。从中区分出两种乡村旅游经营模式:一种是为了适应当地乡村现代化发展需要并在当地政府支持下发展起来的乡村旅游示范村;另一种则是由个人开发且相对独立的小型农家乐或乡村旅游景点。这些地区乡村旅游的快速发展既有利于当地发展支柱产业,调整产业结构,扩大经济活动范围,也为城市居民重新审视乡村世界提供新视角。     

企业家精神与政商关系——浙江政商关系的

浙商的文化价值取向,包括自力更生、吃苦耐劳,安全稳健、履行责任,爱国敬业、诚实守信;经济上善于创新;政治上务实谨慎,又灵活柔慧机变,这些特点都是浙商精神的组成部分。企业家精神是决定政商关系的内源性因素,浙商精神的这些特点构成了浙江政商关系的基础,也从价值观和心智模式上决定了政商关系的特征和类型。     

Relations for Moments of Progressively Type-II Censored Order Statistics from Log-Logistic Distribution with Applications to Inference

In this article, we establish several recurrence relations for the single and product moments of progressively Type-II right censored order statistics from a log-logistic distribution. The use of these relations in a systematic recursive manner would enable the computation of all the means, variances and covariances of progressively Type-II right censored order statistics from the log-logistic distribution for all sample sizes n, effective sample sizes m, and all progressive censoring schemes (R ₁,…, R _m ). The results established here generalize the corresponding results for the usual order statistics due to Balakrishnan and Malik (1987 Balakrishnan , N. , Malik , H. J. ( 1987 ). Moments of order statistics from truncated log-logistic distribution . J. Statist. Plann. Infer. 17 : 251 – 267 .[Crossref], [Web of Science ®] , [Google Scholar]) and Balakrishnan et al. (1987 Balakrishnan , N. , Malik , H. J. , Puthenpura , S. ( 1987 ). Best linear unbiased estimation of location and scale parameters of the log-logistic distribution . Commun. Statist. Theor. Meth. 16 : 3477 – 3495 .[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]). The moments so determined are then utilized to derive best linear unbiased estimators for the scale- and location-scale log-logistic distributions. A comparison of these estimates with the maximum likelihood estimates is made through Monte Carlo simulation. The best linear unbiased predictors of progressively censored failure times is then discussed briefly. Finally, a numerical example is presented to illustrate all the methods of inference developed here.     

Recurrence relations for single and product moments of progressively Type-II censored order statistics from a generalized half-logistic distribution with application to inference

In this paper, we establish several recurrence relations for the single and product moments of progressively Type-II right-censored order statistics from a generalized half-logistic distribution. The use of these relations in a systematic recursive manner enables the computation of all the means, variances, and covariances of progressively Type-II right-censored order statistics from the generalized half-logistic distribution for all sample sizes n, effective sample sizes m, and all progressive censoring schemes (R ₁, …, R _m ). The results established here generalize the corresponding results for the usual order statistics due to Balakrishnan and Sandhu [Recurrence relations for single and product moments of order statistics from a generalized half-logistic distribution with applications to inference, J. Stat. Comput. Simul. 52 (1995), pp. 385–398.]. The moments so determined are then utilized to derive the best linear unbiased estimators of the scale and location–scale parameters of the generalized half-logistic distribution. The best linear unbiased predictors of censored failure times are discussed briefly. Finally, a numerical example is presented to illustrate the inferential method developed here.
