作业成本法在高校教学管理中的应用

随着高教事业的蓬勃发展,教学成本的核算和控制已成为教学管理者所关注的问题.本文通过作业成本法在教学成本核算中的应用,从分析作业动因的角度出发,来探讨如何在教学管理中对教学成本实施有效控制,提高教学资源的利用率.     

进阶式创新创业教育课程体系的构建与实施策略

当前,我国高校的创新创业教育课程体系从总体上来看还缺乏系统性、实践性、针对性和层次性。无论是创新创业教育教学自身的独特规律、社会对创新创业人才的需求特点,还是国务院相关文件都要求高校要构建系统的、有层次的进阶式创新创业教育课程体系。高校可以面向全体低年级的学生、有创新创业兴趣的学生、正在创业的学生三类群体分别设置创新创业通识模块、创新创业孵化模块、创新创业精英模块,并开设有针对性的创新创业教育课程,同时通过理论课程与实践课程的科学合理配置来使之层次分明、有序衔接。?更多还原     

生存的智慧与苦难的温情

吴刘维的作品充满着浓郁的生活气息,其主人公大都是小人物,虽然生活艰辛,却仍不屈不挠,有着令人钦佩的生存智慧,面对生活中无法避免的困境和挫折,他们保持着积极向上的乐观心态,踏踏实实过好每一天,于苦难中彰显温情。如果说生活的曲折和残酷使吴刘维作品带上强烈的现实主义特色的话,那么,曲折和残酷之外的美好和温暖则使其作品打上了深刻的浪漫主义烙印,他试图用复调叙事的艺术手法使"生存的智慧"和"苦难的温情"两大主题得到完美交融和高度统一。     

“A DIAMOND IS FOREVER” AND OTHER FAIRY TALES: THE RELATIONSHIP BETWEEN WEDDING EXPENSES AND MARRIAGE DURATION

In this study, we evaluate the association between wedding spending and marriage duration using data from a survey of more than 3,000 ever‐married persons in the United States. Controlling for a number of demographic and relationship characteristics, we find evidence that marriage duration is inversely associated with spending on the engagement ring and wedding ceremony.

面向大数据驱动的城市生命线管理

城市生命线管理是城市应急管理的关键领域和核心内容,是国家基础设施治理的基本要求和重要保障。城市生命线是维系城市居民生产和生活必不可少的基础设施,是关系城市根本安全的相互关联和相互依存的关键系统。由于城市生命线具有基础性、公共性、系统性、关联性、专业性、复杂性和脆弱性的特点,因此城市生命线管理需要遵循永续发展原则、循数管理原则、成本控制原则、科学评估原则、法治保障原则,需要从城市交通大数据、城市能源大数据、城市水务大数据、城市医疗大数据、城市通讯大数据、城市消防大数据、城市防务大数据方面建立数据分类管理系统,积极开展城市生命线空间管理、城市生命线时间管理、城市生命线运维管理、城市生命线监测管理、城市生命线应急管理和城市生命线协同管理。毫无疑问,城市生命线管理离不开大数据思维的规划与设计,离不开大数据技术的支撑和支持。从一定程度上来说,面向大数据时代的城市生命线管理必须建立以风险为中心的城市生命线管理体制、完善的城市生命线公共数据平台、大数据驱动的城市生命线系统容量和大数据驱动的生命线应急管理预案。随着互联网、大数据和人工智能的迅猛发展,城市生命线管理将会越来越走向循数化、精准化、智能化和法治化。

Penrose's The Theory of the Growth of the Firm: An Exemplar of Engaged Scholarship

Edith Penrose's (1959) classic book, The Theory of the Growth of the Firm, made a substantial impact on strategic management research, especially in the context of the resource‐based view of the firm, and the ripple effects of her impact continue to unfold today in various disciplines. The book serves as a remarkably rich source of inspiration for scholarly research and a generative source of ideas, which are poised to be further developed. In this study, we examine Penrose's (1959) classic and provide: (1) the process by which this book came about; (2) a summary of its key ideas; (3) some implications for operations management research; (4) the subsequent impact of the book, in which we focus on mathematical models; and (5) a discussion of some of the research lessons learned from this exemplar of engaged scholarship. We invite management science and operations scholars to discover the rich scientific world of Edith Penrose and experience the product and process of her research creativity.     

Some comparative studies on testing parallelism of several straight lines under heteroscedastic variances

This paper examines the robustness of the Welch test, the James test as well as Tan's ANOVA test (to be referred as F_β test) for testing parallelism in k straight lines under heteroscedasticity and nonnormality. Results of Monte Carlo studies demonstrate the robustness of all tests with respect to departure from normality. Further, there is hardly any difference between these methods with respect to both power and size of the test.     

On structural models and a theorem of d. basu

Structural inference as a method of statistical analysis seems to have escaped the attention of many statisticians. This paper focuses on Fraser’s necessary analysis of structural models as a tool to derive classical distribution results.

A structural model analyzed by Zacks (1971) by means of conventional statistical methods and fiducial theory is re-examined by the structural method. It is shown that results obtained by the former methods come as easy consequences of the latter analysis of the structural model. In the process we also simplify Zacks1 methods of obtaining a minimum risk equivariant estimator of a parameter of the model.

A theorem of Basu (1955), often used to prove independence of a complete sufficient statistic and an ancillary statistic, is also reexamined in the light of structural method. It is found that for structural models more can be achieved by necessary analysis without the use of Basu’s theorem. Bain’s (1972) application of Basu’s theorem of constructing confidence intervals for Weibull reliability is given as an example.
