Why Distinguish Between Statistics and Mathematical Statistics–The Case of Swedish Academia

A separation between the academic subjects statistics and mathematical statistics has existed in Sweden almost as long as there have been statistics professors. The same distinction has not been maintained in other countries. Why has it been kept for so long in Sweden, and what consequences may it have had? In May 2015, it was 100 years since Mathematical Statistics was formally established as an academic discipline at a Swedish university where Statistics had existed since the turn of the century. We give an account of the debate in Lund and elsewhere about this division during the first decades after 1900 and present two of its leading personalities. The Lund University astronomer (and mathematical statistician) C. V. L. Charlier was a leading proponent for a position in mathematical statistics at the university. Charlier's adversary in the debate was Pontus Fahlbeck, professor in political science and statistics, who reserved the word statistics for ‘statistics as a social science’. Charlier not only secured the first academic position in Sweden in mathematical statistics for his former PhD student Sven Wicksell but also demonstrated that a mathematical statistician can be influential in matters of state, finance as well as in different natural sciences. Fahlbeck saw mathematical statistics as a set of tools that sometimes could be useful in his brand of statistics. After a summary of the organisational, educational and scientific growth of the statistical sciences in Sweden that has taken place during the last 50 years, we discuss what effects the Charlier–Fahlbeck divergence might have had on this development.     

加强人防工程安全管理工作的探讨

国防工程发展建设至今,基本已经趋于健全,其包含万千,由众多部分组成。在国防工程的众多组成部分之中,对于城市以及民众具备有重要意义的人防工程就不可不提,其存在是将深埋地下的空间与资源进行最大化发掘及利用,从而做到与其他国防工程组成部分契合,实现立体化国防工程的建设发展。人防工程虽然不显于人前,但其重要性却无人可以忽略,其对于城市建设发展、民众生命利益保障奠定着坚实基础。     

电气工程及其电气自动化的控制系统应用

基于BIM技术的工程造价精细化管理研究

为实现工程造价精细化管理目标,需要各个环节的相互配合来达到资源优化配置。BIM技术依托虚拟建模技术,实现了对工程项目的数字化建造管理。实践证明,将BIM技术融入项目工程造价管理体系中,有助于提升工程造价管理的整体质量。论文立足工程造价精细化管理的内涵,剖析了BIM技术在工程造价精细化管理中的应用价值,并提出了BIM技术在工程造价精细化管理中的具体应用策略。     

Stress and turnover intents in international organizations: social support and work–life balance as resources

Abstract

This study investigates whether work opportunities have an impact on stress and the related turnover intentions of employees working in intergovernmental international organizations (IOs). It contextualizes the job resources and demands model within IOs’ specific work conditions. The empirical test is based on original data from a survey administered in four major organizations of the United Nations system. Results demonstrate that social work opportunities and work–life balance are organizational levers reducing stress and willingness to quit for employees who are facing red tape or the stresses of being an expatriate. In this context, the relationships between these work opportunities and turnover intention are partially mediated by stress. Contextualized HR management propositions are made to help organizations coping with these management challenges.

疫情期间国际工程投标报价风险分析及费用计算方法研究

随着我国经济的快速发展和“走出去”、“一带一路”倡议的实施,越来越多的企业在政府的带动下开始进军国际市场,但是国际工程往往施工周期长、金额较大、技术复杂、政府干预较多、不确定性因素多,风险与机遇并存,针对2020年全球新冠病毒蔓延这一特殊的时期,企业更应在投标阶段做好风险分析、测算、管控工作,合理规避风险,总结经验教训,保证企业履约能力和竞争性。     

土木工程房屋建筑施工管理问题与策略评价

土木工程房屋建筑一直以来是建筑行业的一大重点,其中施工管理的具体落实对整个工程的质量起着决定性的作用。随着人们生活水平的不断提升,土木工程房屋建筑也在持续地发展。一旦施工管理环节出现问题,在降低工程质量的同时还会危及人员的生命安全。因此,论文通过对当前土木工程房屋建筑施工管理存在的问题进行简要的分析,综合当前建筑工程发展的局势,提出针对性的整改建议。     

房屋土建工程质量监督管理问题与强化建议探究

随着社会经济的快速发展,我国的房屋建筑工程也随之发展起来。建筑施工中无论是技术还是人员的配置都日趋合理,但同时一些问题也逐渐显现出来,如工程施工人员的素质水平不高、建筑市场混乱等,使得工程质量受到了影响,所以我们必须要加强对房屋土建工程的质量监管。
