双离合自动变速器电控电动换挡执行机构仿真优化与试验对比

为了提高双离合变速器在车辆上的换挡品质,提升电气化换挡执行机构的工作效率,给出执行机构性能与换挡品质评价准则;通过两种不同双离合变速器电控电动执行机构的工作原理与性能分析,基于MATLAB数值仿真方法优化出最高效率进行试验.基于车辆6个维度的换挡工况对二者所搭载的变速器分别进行试验与CAN线数据采集,对比研究两种机构优缺点,通过雷达图的方式进行优劣说明.结果表明,两种执行机构传动效率可达70％且换挡品质相当.可见Tip in tip out工况对二者要求最为严格.     

Executive Compensation and Financial Performance Measures: Evidence from Significant Financial Institutions

We survey the use of financial performance measures in determining executive pay among significant Australian financial institutions. We document evidence of the pervasiveness with which externally disclosed non‐GAAP (non‐Generally Accepted Accounting Principles) financial measures are also used internally to determine variable remuneration, with the apparent popularity of cash profit after tax in short‐term incentives plans. Our evidence also highlights the increasing use of peer group‐adjusted measures (e.g., relative cash earnings per share and return on equity ranking against a peer group) in determining longer‐run incentives, despite the fact that members of the peer group do not measure financial performance in a directly comparable manner. Detailed analysis of the four major trading banks (Australia and New Zealand Banking Group, Commonwealth Bank, National Australia Bank and Westpac) reveals differences in the way non‐GAAP earnings measures are calculated across the major banks, as well as some variation over time in the way individual banks measure performance. We also document evidence of non‐GAAP earnings restatements, with around 25% of non‐GAAP results subsequently being restated. These restatements are more likely to result in a downward revision of the initially reported non‐GAAP result than an upward revision. We therefore conclude that existing measures of financial performance used to determine senior executive compensation are not as ‘objective’, as might be assumed.

选择数量对满意度的影响——一个有调节的中介模型

增加选择数量是否会提高满意度是经济学、心理学和营销学的热点问题。当消费者对某一刺激目标同时存在积极和消极的评价时，即矛盾态度怎样影响选择数量和满意度的关系？2个实验结果表明，选择数量对满意度的影响是通过决策困难水平实现的，当选择数量影响决策困难水平时，会产生选择超载。矛盾态度对决策困难水平与满意度的关系有调节作用，对矛盾态度较高者，选择“多多益善”，选择数量增加使消费者满意度提高；相反，对矛盾态度较低者，选择“适可而止”，选择数量增加使消费者满意度降低。     

一种基于Excel的跨系统数据整合分析方法 ——以某三甲医院零星维修成本核算为例

针对当前信息化智能化过程中,单位各部门自建系统相互孤立、数据标准不一致,难以互联互通,而在管理实践中往往需要在多个系统数据整合分析,而这样的需求常常难以得到信息部门及时反馈,立项难、开发慢.针对这样的问题,本文以某三甲医院零星维修成本核算为例,介绍了一套基于Excel的,适合非信息专业人员获取数据,清洗数据,整合数据,分析数据的解决方法.     

基于第二课堂建设的大学生素质教育实践探索

近年来在大学生素质教育的过程中,单一的课堂教育已经无法满足学生需求。第二课堂作为第一课堂的拓展性载体,能够通过对第一课堂的拓展为大学生营造良好的学习环境与身心健康成长的氛围,有助于素质教育工作的开展。高校应重视第二课堂的设计,在第二课堂的支持下全面开展素质教育工作,通过多种措施培养学生的专业素质和综合素养,为大学生的后续发展夯实基础。     

基于ANSYS Workbench电加热支架结构运输断裂分析

随着我国数据中心制冷设备制造技术不断发展,对设备结构的设计质量及可靠性要求越来越高.为改善某项目电加热支架结构运输后的断裂问题,利用ANSYS有限元分析方法对加热器支架运输断裂问题进行静力学、随机振动分析,确认电加热支架结构应力分布、安全系数薄弱位置,并通过对电加热支架结构"几型"的设计优化,在多个项目中应用且运输到西北地区后观察均未出现振动断裂现象,取得良好的改善效果.     

Influence of livelihoods on climate change adaptation for smallholder farmers in the Mekong Delta Vietnam

Farmers in the Vietnamese Mekong Delta face a wide range of climate-related and hydrological factors which threaten rice production. Smallholder farmers must adapt to climate change to sustain rice production as their central and most important livelihood activity. A sample was stratified across agro-ecological areas in the Delta affected by flooding, alluvial soils, acid sulphate soils, and saline water intrusion and by derived farmer typologies. A rural livelihoods approach was used in focus group discussions and in-depth interviews to identify and enumerate enabling and constraining adaptation factors. Smallholders experienced diverse natural hazards such as floods, abnormal rains, high temperatures, water scarcity, and salinity intrusion specific to the agro-ecological areas. Adaptation was constrained by labour shortages, water quality, topography, access to combine harvesters, transportation infrastructure, dryers and household savings. Adaptation was enabled by farming techniques and experience, cooperative groups, water quantity, access to information, and ability to purchase agro-chemicals through credit. Small farmers (< 1?ha) were more constrained than large farmers (> 1?ha) who had an expanded livelihood asset base. A range of policy implications are discussed, but adaptation is not just about technological fixes but requires overall improvements in a range of human, social and financial components.     

儒家传统文化与公司违规行为*——基于中国家族上市公司的分析

本文按照“文化-行为”的逻辑，探讨了作为非正式制度的重要组成部分之儒家传统文化对公司违规行为的影响。本文以2007—2014年沪深两市的中国家族企业上市公司为研究样本，考察了儒家传统文化对上市公司违规行为的影响以及其与正式制度（法律）的交互作用。研究发现，儒家传统文化影响力越强，上市公司违规行为发生的概率越低；并且在儒家传统文化与正式制度（法律）两者交互叠加作用时上市公司违规行为发生的概率更低。     

普惠金融发展的地区差异、收敛性及影响因素研究*——基于中国省级面板数据的检验

本文利用2005—2016年省级面板数据，对我国各地区普惠金融发展水平进行测度，并在此基础上探讨其收敛性及影响因素。结果表明：（1）我国普惠金融发展水平在考察期内总体偏低，并且呈现出显著的地区差异性。（2）绝对β收敛在全国、中部和西部均存在，而东部不存在；条件β收敛在全国、东部和西部均存在，而中部不存在。（3）政府干预程度、市场化程度、人力资本质量、非正规金融以及外商直接投资对普惠金融发展均具有重要的影响。
