研究生学术道德建设的现状及其改善途径

近年来,研究生中出现的学术道德失范现象着实令人担忧,问题的出现除学生个体和社会大环境的原因外,作为高校的研究生教育工作者,更是要进行深刻的自我反思。本文主要从研究生学术道德失范的具体情况入手,反思学术道德建设中存在的问题和不足,并提出改善学术道德建设的途径。     

知识型员工流失的深层研究——基于心理契约的视角

知识型员工由于其地位和作用的特殊性,一直是企业竞争的主要对象,其流动率也一直较高。知识型员工流失在很大程度上是心理契约违背的必然结果,因此,重构和优化心理契约至关重要。具体而言,在招聘、入职、变动和离职四个阶段,企业应分别采取真实岗位预视、建立动态档案、加强沟通、及时补偿和离职面谈等措施,防止知识型员工流失。     

金融知识获取圈层对农户农地抵押贷款参与的影响研究——基于失地风险感知的中介效应分析

积极稳妥推广农地抵押贷款融资业务,持续深化农村土地资产与金融资源的有机衔接是完善金融服务乡村振兴战略的关键内容,深入探究农户金融知识获取的人际圈层来源以及失地风险感知因素对完善农地抵押贷款相关制度建设具有重要意义。文章首先理论阐释了金融知识获取圈层、失地风险感知对农户农地抵押贷款参与的影响,详细剖析了农户失地风险感知的中介机理;然后采用因子分析法测度金融知识获取圈层变量,提取4个公共因子分别界定为亲属关系圈、朋友关系圈、乡邻关系圈和机构参与圈;最后以陕西、宁夏、山东三省农地抵押贷款试点地区1 312户农户调查数据为样本,利用Logit模型和Bootstrap中介效应检验方法,实证分析了金融知识获取圈层、失地风险感知对农户农地抵押贷款参与的影响,并揭示了失地风险感知的中介效应类型和数值大小。研究结果显示：金融知识获取圈层正向促进农户农地抵押贷款参与,其中金融知识获取亲属关系圈的促进作用大于机构参与圈;金融知识获取圈层负向影响农户失地风险感知,机构参与圈的影响最大,亲属关系圈次之,朋友关系圈最小;在四个金融知识获取圈层下,失地风险感知均对农户农地抵押贷款参与具有负向影响;失地风险感知在金融...     

文化意象的失落与扭曲:诗歌翻译之忌

意象是诗歌的生命,当意象涉及到某种文化的深层意蕴,这个意象就成为文化意象.在诗歌翻译中,对原作的文化意象进行任意取舍或扭曲都是不当的.对原作物象的尊重才是诗歌文化意象翻译的正途.     

逆向供应链的非合作代价分析

为衡量基于价格合同的逆向供应链运作效率,将非合作代价(PoA)概念引入逆向供应链.考虑废旧产品供应的不确定性,分析了推式和拉式两种结构的两级和多级逆向供应链在分散决策时效率损失的上界.研究表明,逆向供应链并非正向供应链的简单逆过程,这是由于逆向供应链的不确定性主要来自上游端,从而需要考虑废旧产品供应不足导致的缺货风险;推式与拉式两种结构下具有一致的PoA,即分散决策下的效率损失与谁来承担风险无关.此外,逆向供应链级数的递增会加剧供应链效率损失,但逆向供应链级数一定时PoA趋于定值.     

经理行为偏差与企业绩效激励指标的确定

股东在面对具有行为偏差的经理时,如何设计剩余收益作为激励指标,以促使双方的目标一致,一直是学界和实务界关注的一个问题。如果股东继续沿用传统的基于公司资本成本率计算得到的剩余收益,将使得损失厌恶的经理投资不足,过度自信的经理投资过度。为了改进投资决策,股东需要针对不同行为特征类型的经理设计较公司资本成本率更低或更高的激励相容资本成本率,以有效激励经理做出符合股东利益的投资决策。     

试析《隆中对》兼论关羽之失

诸葛亮未出茅庐便知三分天下,在刘备三顾茅庐时,便提出<隆中对>,为刘备指出发展方向和治国方略.<隆中对>前后可分两大部分.前半部分劝告刘备不要与已拥有百万之众,挟天子以令诸侯的曹操争锋;要与占据江东已历三世,国险而民附,贤能为之用的孙权结盟,不要为敌.指出刘备的发展方向是占有荆州和益州.后半部分为刘备指出五点治国方略和战略部署:(一)联吴抗曹;(二)跨有荆、益;(三)西和西戎,南抚夷越;(四)内修政理;(五)两路出军,一向宛、洛,一出秦川.这五大治国方略和战略部署,由于关羽大意失荆州而受到严重打击,使"跨有荆、益"和"两路出军"的计划落空,吴蜀联盟中断,但诸葛亮在"联吴抗曹"、"西和诸戎,南抚夷越"等方面仍取得了辉煌的成就,对开发四川、云南、贵州作出了突出的贡献.诸葛亮是三国时期一流的政治家、军事家和战略家.     

Spontaneous vaginal birth following induction with intravenous oxytocin: Three oxytocic regimes to minimise blood loss post birth

BackgroundNo evidence was identified in relation to the downward titration/cessation of intravenous oxytocin post spontaneous vaginal birth, in the absence of postpartum haemorrhage (PPH); suggesting clinicians’ management is based on personal preference in the absence of evidence.AimTo determine the proportion of induced women with a spontaneous vaginal birth and PPH, when intravenous oxytocin was utilised intrapartum and ceased 15, 30 or 60 minutes post birth.MethodsThis three armed pilot randomised controlled trial, was undertaken on the Birth Suite of an Australian tertiary obstetric hospital. Incidence of PPH was assessed using univariable and adjusted logistic regression, which compared the effect of titrating intravenous oxytocin post birth on the likelihood of PPH, relative to the 15 minute titration group.FindingsPostpartum haemorrhage occurred in 26% (30 of 115), 20% (23 of 116), and 22% (30 of 134) of women randomised to a 15, 30 and 60 minute titration time post birth, with no statistically significant differences between groups.ConclusionThere was no difference in the incidence of PPH between the three groups. Therefore, we question the benefit of delaying cessation of intravenous oxytocin for 60 minutes post birth. Further investigation in this cohort is recommended, to compare the incidence of PPH when intravenous oxytocin is ceased either immediately, or 30 minutes post birth. This research is warranted, as an evidence-based framework is lacking, to guide midwives globally in relation to their management of intravenous oxytocin post an induced spontaneous vaginal birth, in the absence of PPH.     

E-Bayesian estimation of the exponentiated distribution family parameter under LINEX loss function

This paper is concerned with using the E-Bayesian method for computing estimates of the exponentiated distribution family parameter. Based on the LINEX loss function, formulas of E-Bayesian estimation for unknown parameter are given, these estimates are derived based on a conjugate prior. Moreover, property of E-Bayesian estimation—the relationship between of E-Bayesian estimations under different prior distributions of the hyper parameters are also provided. A comparison between the new method and the corresponding maximum likelihood techniques is conducted using the Monte Carlo simulation. Finally, combined with the golfers income data practical problem are calculated, the results show that the proposed method is feasible and convenient for application.
