顶岗支教实习中的师生和谐关系研究

顶岗支教实习是高校实习改革的一个积极探索,而高师生在实习中建立的师生关系是否和谐直接关系到中小学学生的心理健康和全面发展、关系到教育实习的效果、关系到顶岗支教实习方式的延续。目前顶岗支教实习中所建立的师生关系不容乐观,而和谐师生关系的建构不但需要社会、高校、中小学校、学生的支持和配合,更重要的是高师生要更新教师观念,不断提升自身素质,用爱、理解和尊重来构建和谐融洽的师生关系。     

商誉和价格影响需求的易逝品动态定价与广告决策

研究需求受价格和商誉共同影响下易逝品动态定价与广告投资策略的联合决策问题。在初始库存确定的情形下,在某待定销售周期内,企业通过投入广告提升自身商誉从而拓宽市场,以企业利润最大化为目标,建立联合最优动态定价及广告投资策略模型。应用庞特里亚金极大值原理,求得不同系统参数下最优动态定价和广告投资策略及最优的销售周期。通过数值算例验证方法的有效性,结合参数灵敏度分析检验系统参数对最优策略的影响并给出相应管理意义。     

中国社会传统家庭伦理父子关系的现代扬弃

中国封建社会伦理之中,积淀了丰富的以＂尊亲＂、＂顺亲＂、＂养亲＂等为主要内容的父子伦理精义;在中国社会结构由金字塔型演变为橄榄型、步入了后喻社会时代的今天,封建社会时代形成的许多父子伦理内容和沟通模式已不适合当今社会时代的发展要求。在今日中国社会伦理系统之中,应该建立新型的父子伦利（互利）关系。这既需要借鉴现代社会的＂互喻＂模式,又要采补传统伦理的精髓内容。     

论校企合作关系的性质及其启示

校企是两种不同性质的社会组织,具有差异性和相互依赖性,由此决定校企合作关系是一种交换关系,正确认识这一关系,对于高等院校实现校企有效合作具有重要的启示——遵循交换规律是实现校企合作的关键;高等院校具有企业所需的资源或产品是实现校企合作的必要条件;加强校企沟通是实现校企合作的重要条件。     

切线模量法确定强夯地基承载力的现场试验研究

平板载荷试验是检验强夯加固填土地基承载力的重要手段，基于平板载荷试验的切线模量法以安全系数和允许沉降两个控制因素结合Terzaghi极限承载力理论可计算不同沉降要求的地基承载力。为了验证切线模量法计算强夯地基承载力的可行性和优越性，对现场填土地基进行强夯加固后进行平板载荷试验和超重型动力触探试验，以三组[WTBX]平板载荷试验9个试验点的测试结果为基础，反演该地基土性参数并通过切线模量法绘制p s曲线，发现切线模量法计算的p s曲线与现场p s曲线能够很好的吻合，故可用切线模量法计算基础中心不同沉降量所对应的地基承载力,且能够弥补平板载荷试验和动力触探测试方法的不足，故为浅基础的设计提供了一条新的途径。

Relationship Quality in Marital and Cohabiting Unions Across Europe

In this study, the authors used data from the first wave of the Generations and Gender Survey to investigate relationship quality among currently married and cohabiting individuals ages 18 to 55 (N = 41,760) in 8 European countries (Bulgaria, France, Germany, Hungary, Norway, Romania, Russia, and The Netherlands). They expected to find fewer differences between cohabitation and marriage in countries where cohabitation is widespread. Controlling for a range of selection characteristics of respondents and their partners (e.g., common children, union duration, and education), the analyses showed that in all countries cohabiters more often had breakup plans and were less satisfied with their relationships than individuals who married. This cohabitation gap in relationship quality was largest in Russia, Romania, and Germany, which indeed were among the countries in the current sample where cohabitation was least prevalent.     

Some Results Based on a Version of the Generalized Dynamic Entropies

We propose new dynamic measures of uncertainty based on the notion of generalized dynamic entropy introduced in Di Crescenzo and Longobardi (2006). These can uniquely determine distribution functions in continuous and discrete cases, and the characterizations of some well-known distributions are provided. We also define some orderings and aging notions based on the generalized dynamic measures, and prove some of their properties, obtaining as corollaries results that have recently appeared in the literature.     

Optimal hedging through limit orders

This article applies the methods of stochastic dynamic programming to a risk management problem, where an agent hedges her derivative position by submitting limit orders. Therefore, this model is the first, in the literature on optimal trading with limit orders, to handle a problem of hedging options or other derivatives. A hedging strategy is developed where both the size and the limit price of each order is optimally set.     

Zen and the art of aut-ethnography: a tribute to Robert M. Pirsig

With the passing of Robert M. Pirsig, I felt that it was an appropriate time to write a tribute to his work and the influence it has had on my own theorising in regard to autistic ways of being. This reflection utilises the concept of an ‘aut-ethnography’ to examine passages that I had highlighted word by word when I first read Pirsig’s book: Zen and the Art of Motorcycle Maintenance. These fragments contain links to a number of theoretical ‘lines of flight’ within my own work and that of others, from his concepts of dynamic ‘quality’ to his discussion on the tension between scientific method and lived experience.
