新时期建筑工程施工管理模式创新研究

施工管理是建筑工程的重要环节，是保障建筑工程质量的关键举措，施工企业要加强对施工管理的重视，结合自身实际情况建立健全的施工管理模式，以促进施工企业实现可持续发展。但从目前建筑工程的施工管理情况看，部分施工企业的施工技术水平不高，建筑工程现场施工管理过于薄弱，严重影响建筑工程质量。基于此，文章结合实际工程案例，分析施工管理模式中存在的问题，针对问题提出多样化的创新管理模式，如EPC工程管理模式、DBB管理模式、合作伙伴工程管理模式，利用数字化技术创新建筑工程施工管理模式，能提高施工质量，提高工程施工管理水平，为施工人员提供全新的管理思路，确保建筑工程顺利施工建设。     

建筑工程文明施工管理

在施工的过程中，创造好的施工环境，就是以人为本的观念。在施工前创造良好的环境，施工过程中保持良好的环境，这是对自己生命的关爱，也是对别人生命的关爱。以前工程施工过程中忽视了文明施工，是因为施工管理存在薄弱环节，对文明施工的投入不够、规范不全、没有标准或标准不高。文明施工是技术的创新，强调文明施工，意味着施工过程中要不断采取新技术、新工艺、新方法，革新施工手段，完善技术设备，文明施工是企业发展的内在要求。

Benefiting from negative feedback

This article discusses why it is so hard for people to benefit from negative feedback. We examine factors involved in the effective use of negative feedback. Our analysis suggests that the main obstacles to the effective use of negative feedback stem from the failure to obtain it and the failure to conduct an accurate appraisal of it. This is in contrast to research indicating that the main obstacle to the effective use of positive feedback lies more in avoiding its detrimental consequences after repeated exposure to it than in obtaining it or appraising it.

混凝土构筑物裂缝原因分析与处理

混凝土结构出现裂缝是不可避免的,其也是属于材料的特性之一,但是应用于建筑工程中要将其控制在无害的范围内,即不会影响到结构的正常功能。混凝土是由多种材料结合而形成的混合体,因此,混凝土属于脆性材料,如果压力、温度以及外力作用于混凝土结构上,会导致其出现裂缝。本文主要是针对裂缝进行有害与无害的分析,并就有害裂缝的形成原因以及如何处理有害裂缝进行分析。     

True and fair in the Czech Republic: a note on local perceptions

With the collapse of communism in Czechoslovakia’, and the subsequent desire of Czechoslovakia to join the European Union, in common with other countries in Central Europe, Czechoslovakia utilized the Fourth Directive as a ‘toolkit’ in designing part of its new accounting legislation. In incorporating the Fourth Directive, it has also included the requirement for financial statements to show a ‘true and fair’ view. Given the confusion over the exact meaning of ‘true and fair’ it is interesting to study how ‘true and fair’ has been introduced into the Czech Republic, and what it seems to signify for those who implemented it and for those who are preparing and using financial statements. Our initial findings indicate that ‘true and fair’ varies in its significance for the groups of individuals involved in preparing and using financial statements and that it may have particular significance for some groups of accountants who wish to secure specific advantage within the Czech economy.With the collapse of communism in Czechoslovakia’, and the subsequent desire of Czechoslovakia to join the European Union, in common with other countries in Central Europe, Czechoslovakia utilized the Fourth Directive as a ‘toolkit’ in designing part of its new accounting legislation.

Approximating the distribution of the two-stage least squares estimator when the concentration parameter is small

This paper presents a new approximation to the exact sampling distribution of the instrumental variables estimator in simultaneous equations models. It differs from many of the approximations currently available, Edgeworth expansions for example, in that it is specifically designed to work well when the concentration parameter is small. The approximation is remarkable in that simultaneously: (i) it has an extremely simple final form; (ii) in situations for which it is designed it is typically much more accurate than is the large sample normal approximation; and (iii) it is able to capture most of those stylized facts that characterize lack of identification and weak instrument scenarios. The development leading to the approximation is also novel in that it introduces techniques of some independent interest not seen in this literature hitherto.

Organizational passages—Diagnosing and treating lifecycle problems of organizations

In this article a model for identifying organizational styles is presented. Such a typology has been found to be repetitive as a pattern in a significant number or organizations and it has been verified by hundreds of executives as reflecting their experience.The model enables an organization to foresee the problems it will face as it grows over time. Furthermore, it provides tools for prescribing effective organizational treatments-organizational therapy and surgery. It is a contingency model in that it presents a framework for prescribing the treatments most likely to be effective depending on the lifecycle stage of the organization.
