高校大学生诚信缺失现象的隐忧及思考

诚信是一种道德实践，也是中华民族的传统美德。诚信对个人的世界观、人生观和价值观的形成以及个人人格的完善、人的全面发展皆具有十分重要的作用。大学生的诚信教育问题与社会主义市场经济建设和发展密切相关，值得全社会的广泛重视。文章以当前大学生的诚信教育为切入点，指出现阶段大学生诚信意识的缺失现状，并从社会、家庭、学校及大学生自身这四个方面分析其缺失原因，并据此提出有效对策。     

钱学森对管理科学的丰富与发展

钱学森倡导的社会系统工程是组织管理现代化建设的技术,管理科学是它的基础科学。钱学森从人类活动的广阔视野,从运筹学概括出事理和物理的概念,推动了从研究物质的科学向研究事理科学的转变。同时,他通过对西方行为科学的分析与批判,将伦理学与法学纳入行为科学,拓宽了中国行为科学的视野。从战略科学家的角度,钱学森通过创建系统科学理论,推动了中国社会主义建设的组织管理水平的提高。     

The pricing of defaultable bonds under a regime-switching jump-diffusion model with stochastic default barrier

In this paper, we investigate the price for the zero-coupon defaultable bond under a structural form credit risk with regime switching. We model the value of a firm and the default threshold by two dependent regime-switching jump-diffusion processes, in which the Markov chain represents the states of an economy. The price is associated with the Laplace transform of the first passage time and the expected discounted ratio of the firm value to the default threshold at default. Closed-form results used for calculating the price are derived when the jump sizes follow a regime-switching double exponential distribution. We present some numerical results for the price of the zero-coupon defaultable bond via Gaver-Stehfest algorithm.     

婚姻——一种身份性契约——兼论“第三者责任”

婚姻关系是人类生命得以延续和社会发展的基础，保护婚姻关系有利于社会的稳定。然而，在生活中，第三者破坏他人婚姻的事件屡见不鲜，我国《婚姻法》第四十六条排除了第三者承担离婚损害赔偿责任的可能性，因而在多数情况下第三者破坏他人婚姻不用承担责任。这条规定不但不利于保护婚姻关系的稳定，而且会引发一系列的社会问题，如情杀、仇杀、离婚率的上升、单亲家庭增多等。对于破坏他人婚姻的第三者责任，在立法上应予以明确规定，以更好地保护婚姻关系、稳固家庭。     

复句的系统复杂化与自繁殖

文章研究表明,偏正复句存在着有序的系统复杂化和自繁殖活动。它从联合领域的承接复句跨界向偏正领域的因果复句偏移开始。假设关系是在继承因果联系的基础上,由当下因果事态向预期因果事态变异而成,其所建立起的因果预期联系,为偏正复句的继发偏移补充了必备的逻辑基础。接下来,偏正复句通过模态变异、顺逆变异、项目变异、标记替换,更加活跃地以家族相似关系向其他各类型偏移。在偏移中,常量和变量的选择常发生变化,当一次繁殖成功后,新繁殖的复句类型便选择新的常量和变量,进行再度扩张,从而构成复句类型的链式演化。     

我国个人住房抵押贷款违约风险影响因素的实证研究

 次贷危机的爆发提醒人们重新认识个人住房抵押贷款违约带来的风险。现阶段，我国商业银行已经发放了大量个人住房抵押贷款，那么，哪些因素可能对我国个人住房抵押贷款违约产生显著影响，这是需要我们深入研究的问题。本文在实地调研的基础上，利用637组数据，对影响我国个人住房抵押贷款违约风险的因素进行了实证分析。研究结果发现，借款人受教育程度越高，工作行业稳定程度和垄断程度越高，违约率越低；借款人购买住房面积越大，每月偿还贷款金额与家庭收入之比越高，违约率越高；本地人比外地人违约率高；购买现房借款人比购买期房借款人的违约率高。对违约影响较大的因素依次是住房面积、月还款额占家庭收入比、是否期房、受教育程度。     

人格信任的社会与伦理化的法律——从信任结构看传统中国社会法律的主要品性及其现代转型

从信任结构理论的角度看,传统中国是一个人格信任的社会,由此决定了适用于其中的法律的伦理化品性.只有对这些特点有了明确的把握以后,在中国社会与法律的现代化转型中,我们才能获得更为明晰的前进方向和出路:建立系统信任为主导的社会结构和形式化的法律制度.     

Efficacy of newer medications for lower urinary tract symptoms attributed to benign prostatic hyperplasia: a systematic review

We conducted a systematic review to evaluate the efficacy and adverse effects of newer drugs used to treat lower urinary tract symptoms (LUTS). The drugs were either Food and Drug Administration (FDA) approved for benign prostatic hyperplasia (BPH) or not FDA approved for BPH but have been evaluated for treatment of BPH since 2008. We searched bibliographic databases through September 2017. We included randomized controlled trials (RCTs) lasting one month or longer published in English. Outcomes of interest were LUTS assessed by validated measures. Efficacy was interpreted using established thresholds indicating clinical significance that identified the minimal detectable difference. Twenty-three unique, generally short-term, RCTs evaluating over 9000 participants were identified. Alpha-blocker silodosin and phosphodiesterase type 5 inhibitor tadalafil were more effective than placebo in improving LUTS (moderate strength evidence) but these drugs had more adverse effects, including abnormal ejaculation (silodosin). Anticholinergics were only effective versus placebo when combined with an alpha-blocker. Evidence was generally low strength or insufficient for other drugs. Evidence was insufficient to assess long-term efficacy, prevention of symptom progression, need for surgical intervention, or long-term adverse effects. Longer trials are needed to assess the effect of these therapies on response rates using established minimal detectable difference thresholds, disease progression, and harms.
