管理决策的科学性取决于管理方法、手段和技术的有效性。基于决策问题的系统分析方法是实施科学决策的基础,决策问题的提出是系统科学发展的动因。建设工程管理决策树立系统观点、应用系统方法进行量化和优化是提高其决策质量的有效方法。从系统分析与决策、建设工程管理决策的系统观以及建设选址问题中系统分析方法的应用三个方面理论与实际相结合,阐明了系统量化与优化对于建设工程管理决策的辅助支持作用,以期增强建设工程管理决策活动应用系统方法的自觉性,提高管理决策的质量和能力,促进建筑业的健康良性发展。  相似文献

The state has a twofold relationship to gender change in society, through its overall steering capacity and through the gendered character of its constituent agencies. It is therefore important to understand the experience of gender change in state organizations. The findings from a study of gender relations in ten public‐sector worksites in New South Wales, Australia are presented. There is a widespread consciousness of gender change linked with new labour processes, restructuring and new patterns of management. These changes are uneven and limits to change are visible. Gender is recognized as an organizational problem in specific circumstances, most visibly where men’s resistance to change appears. A number of mechanisms limit the consciousness of gender as a problem. Several trends, including the current strength of neo‐liberalism, converge to make the gender‐neutral workplace the principal goal of gender reform in the public‐sector workplace. This, however, limits the state’s steering capacity in regard to societal gender relations.  相似文献

In the modern western world, the discursive construction of fatherhood and everyday fathering practices has been underpinned by the spatial separation of work from home, of public from private. However, increasing numbers of employees are now working from home and a disproportionate number of these are men with young children. This article draws on new empirical research to examine the implications for fathers and for organizations as home‐working disrupts earlier spatial configurations of fatherhood and fathering practices. The article concludes that as the spatial boundaries between home and work collapse, new accommodations between fatherhood/fathering and organization are emerging. However, these are underpinned by a traditional gender division of labour in the household. More broadly, these findings confirm the inadequacy of static distinctions between public and private, showing that while such distinctions are still used to mark space and time, this is relational, contingent and unstable.  相似文献

This paper examines local authority social workers' decision‐making when considering referrals of children, where the concerns are on the margin of child protection procedures. In doing so, it describes the findings of a qualitative research study undertaken in the policy context of attempts to ‘refocus’ social work practice in the late 1990s and early twenty‐first century. Data collection involved interviews with social workers and parents in 23 cases. Conclusions are that referrals were evaluated on the basis of five key factors, specificity, severity, risk, parental accountability and corroboration, the use of which determined whether an initial assessment or an investigation of alleged abuse took place. The analysis builds on previous work in the child protection field, but demonstrates how the application of these factors differs between cases of child concern and cases of child protection. Policy implications concern the complexity of decision‐making in the uncertain context of limited referral information and it is proposed that the simplistic notion of a continuum of abuse is now outdated.

Mothers' time‐use patterns were compared in families in which infants spent more than 30 hours per week in child care (In‐Care group; n= 143) versus 0 hours per week (At‐Home group; n= 183) from birth to 6 months of age. In‐Care group mothers spent about 12 fewer hours per week interacting with their infants, for about 32% less time; fathers of these infants were more involved in caregiving. The groups did not differ in the quality of mother‐infant interaction. In the In‐Care group, quantity of interaction was related to greater separation anxiety and concerns about effects of maternal employment. Time‐use data were not related to child outcomes at 15 months of age. Results suggest that the effect of extensive time spent apart on the quantity and quality of mother‐infant interaction may be smaller than anticipated.  相似文献

The authors examine the effect of premarital cohabitation on the division of household labor in 22 countries. First, women do more routine housework than men in all countries. Second, married couples that cohabited before marriage have a more equal division of housework. Third, national cohabitation rates have equalizing effects on couples regardless of their own cohabitation experience. However, the influence of cohabitation rates is only observed in countries with higher levels of overall gender equality. The authors conclude that the trend toward increasing cohabitation may be part of a broader social trend toward a more egalitarian division of housework.  相似文献

西方国家高校组织的自主权是通过大学内部立法、决策领导、组织协调、咨询等办学活动来实现的。大学自治组织系统主要由董事会 (校务会 )、校长、评议会等组成。校长由董事会 (校务会 )选举或产生 ,代表其行使学校决策及日常事务管理。大学自治组织一般拥有组织教学、筹集经费、开展学术研究、人事使用等权力 ,而这些权力的行使一方面要受到大学内部各种权力系统、管理层以及利益集团的制约 ,同时还要受到来自大学外部的各种专门组织和社会团体的监督  相似文献
