高校开展咏唱爱国主义歌曲活动的意义和经验分析——以祖国七十大庆高校开展咏唱爱国主义歌曲活动为例

爱国主义歌曲作为对祖国抒发赞颂之情的歌曲,是“光荣颂”“欢乐颂”“祝福颂”的有机统一,是培育和践行社会主义核心价值观的重要载体。从精神价值而言,爱国主义歌曲具有社会公共性、历史恒久性、无比崇高性。高校开展咏唱爱国主义歌曲活动,能增进学生对祖国的自豪之情,提升其民族自信,激发其报国之志。高校开展咏唱爱国主义歌曲活动,即要精选优异的爱国主义歌曲音乐本体,又要注重发挥高校教师的带头作用,还要加强学校各级组织机构和辅导员队伍的引领作用。高校党政领导对这类歌咏活动要进一步提高认识站位、增强重视程度、加强条件支持。     

宋代閤职的内外演变与磨勘叙迁探析

宋代共设有三等閤职，最初供职于閤门，后閤职官员出外任职情况变得普遍，直接推动了外任武官兼带閤职制度的发展，此后閤职作为武官兼带的一种职名，成为奖励军功以及控制武官的一种有效手段。而閤职制度的发展也使閤职作为武臣清选的地位逐渐确立，表现之一就是在磨勘叙迁上较一般武官而言具有一定的优越性。同时，内外不同的閤职在磨勘制度上也有一定的差异，这些差异的产生也加深了閤职作为武臣清选的内涵。     

基于信号博弈的卖方欺诈行为分析

本文主要基于信号博弈的卖方欺诈行为进行研究，假设拍卖中可能存在欺诈型和诚实型两种卖家，其中欺诈行为有概率发生在第二价格拍卖中：欺诈型卖方冒充竞拍者递交仅次于最高价的报价从而获得额外收益。两种卖家根据各自效用选择拍卖形式：第一价格或者第二价格。而竞买者将卖者的选择作为信号，更新对卖方类型的判断，然后制定报价策略。这是一个买卖方信号交叉影响的过程。考虑到拍卖过程中买方价值相关性，本文在建立模型中参考了关联价值原理。针对该模型进行分析，得出了不同情况下的买卖方策略，并且研究了买方报价、买方判断、卖方收益三者之间的关系。文中利用贝叶斯公式对双方的策略选择问题进行预测，与单纯的概率分布方法相比，更具实践价值。     

合作与破裂:山东地方官与大刀会关系研究

山东地方官对大刀会、拳会的宽容的政策与态度由来已久，早在甲午中日战争期间，官军就与大刀会形成默契，在共同缉捕盗匪方面取得显著成效，直至义和团在中外联合势力的绞杀下失败，在此期间，大刀会、拳会等名目的民间团体组织与官府的关系就处在一种半合作半破裂的游离状态，即这种宽容政策具有一定的延续性。就义和团运动而言，大刀会等民间会社势力仅仅是为义和团运动构筑的可能性力量而已，程度很高，却极不稳定，它们有待于官方的开掘、引导与锤炼及外力催逼，即官方对刀会、拳会的宽容态度与政策，以及西方列强、教会势力的威逼现实这两种因素，而前者更为重要。     

Probabilistic population projections for countries with generalized HIV/AIDS epidemics

In 2015, the United Nations (UN) issued probabilistic population projections for all countries up to 2100, by simulating future levels of total fertility and life expectancy and combining the results using a standard cohort component projection method. For the 40 countries with generalized HIV/AIDS epidemics, the mortality projections used the Spectrum/Estimation and Projection Package (EPP) model, a complex, multistate model designed for short-term projections of policy-relevant quantities for the epidemic. We propose a simpler approach that is more compatible with existing UN projection methods for other countries. Changes in life expectancy are projected probabilistically using a simple time series regression and then converted to age- and sex-specific mortality rates using model life tables designed for countries with HIV/AIDS epidemics. These are then input to the cohort component method, as for other countries. The method performed well in an out-of-sample cross-validation experiment. It gives similar short-run projections to Spectrum/EPP, while being simpler and avoiding multistate modelling.     

金沙遗址出土文物太阳神鸟黄金面具青铜立人的藏文化解读

从藏族古代文化的视角来看，金器太阳神鸟图似乎与斯巴嘎巴和迥瓦风轮的观念有关，斯巴嘎巴和迥瓦风轮观涉及藏族本教的空间时间观和宇宙本体观。斯巴嘎巴是藏语的汉语对音，指空间和时间。迥瓦是藏语的汉语对音，指风火水土四元素。风轮是藏语的汉语意思表达，指“风”为元初原动力的宇宙形成观。在藏语言里，黄金面具实为金面。古藏人非常重视头发及其发型，即便是对死者补妆也是如此，在为死者补妆时，发辫被排在了补妆12点数的首选位置，且头发与绿松石相对应。     

Toward a gender politics of aging

The article proposes a Gender Politics of Aging approach to the study of aging societies. The approach recognizes the feminization of old age, ageism’s roots in sexist discourse, and the need to recognize the role of politics in driving demographic debates. Drawing together arguments from feminist gerontology and political demography, the article argues that the intersection of politics and gender must be considered if appropriate responses to an older, feminized demography are to be produced. I conclude that the work of aging feminists provides a rich vein of research and praxis from which a gender politics of aging approach can draw.     

Deliberate acquisition of competence in physiological breech birth: A grounded theory study

Problem

Research suggests that the skill and experience of the attendant significantly affect the outcomes of vaginal breech births, yet practitioner experience levels are minimal within many contemporary maternity care systems.

Service diversification and growth of professional service firms

This study investigates the impact of service diversification on the rate and mode of firm growth in professional service firms (PSFs). Drawing on the extant PSF literature, we identify differing views regarding the growth impact of service diversification. Specifically, some scholars suggest that the external client benefits associated with service diversification should allow PSFs to expand revenues at a rapid pace and pursue less merger and acquisition activity, whereas others imply that increased diversification can cause internal challenges with respect to learning costs, coordination and innovation that can limit the rate of revenue growth and encourage more mergers and acquisitions. We test these competing views using longitudinal data on 137 accounting firms and cross-sectional data on 125 law firms and find that service diversification is negatively associated with the rate of firm revenue growth and positively associated with the use of mergers and acquisitions.     

体验型产品消费行为的羊群效应及机理研究——基于电影行业消费行为的实证解释

互联网环境下消费者购买体验型产品时对网络信息的依赖性很大。因此，研究社交媒体影响下体验型产品的消费者决策选择行为具有现实意义。本文以电影行业的票房偏离及消费跟风现象为切入点，探究体验型产品的羊群效应并对其产生的内在机理进行解释。采集艺恩资讯的票房数据以及豆瓣的电影基本信息及影评等数据作为研究样本，从消费者"羊群行为"视角分析其对电影票房的影响。研究发现：在控制了质量等内生性影响之后，消费者羊群效应依然存在；产品特征信息对羊群效应起到了调节作用，从而形成理性跟随；采用预期差异模型可以解释消费者实现理性跟随的过程。研究结论对于电影行业宏观政策制定及对体验型产品合理进行营销推广提供了理论基础与实证依据。
