设计-施工总承包模式在南京地铁盾构工程中应用 总被引:1,自引:0,他引:1
设计—施工总承包模式的特点和优点已经得到业界的广泛认同,但该模式目前在我国成功应用的例子还不是很多。通过对南京地铁盾构工程在不同承包模式下合同支付费用变更的研究,分析了设计—施工总承包模式在该工程中应用的优越性,并进一步对城市轨道交通建设中复杂、特殊工程的承包模式提出了建议。 相似文献

戊烷的生产与市场分析 总被引:5,自引:0,他引:5
戊烷原料主要来源于炼油厂。戊烷产品用途广泛,可用作发泡剂、溶剂、化工原料等。目前国内高纯度异戊烷、正戊烷、环戊烷及混合戊烷发泡剂生产厂有36家,生产能力150kt/a左右.我国戊烷的年消费量近66kt,其中,EPS(发泡聚苯乙烯)戊烷发泡剂的消费量约占总消费量的45%;聚氨酯的发泡剂消费戊烷约占总消费量的50%;线性低密度聚乙烯戊烷载溶剂消费量约占总消费量的5%。国内戊烷供大于求,但高档产品供应不足。所以,“十五”期间新建装置一定要采用国内较为先进的工艺技术,采用较廉价的原料气,确保产品质量,最大限度的降低生产成本,同时加强市场开发,提高产品的市场竞争力。 相似文献

The UK government has set an ambitious target of reducing greenhouse gas emissions by 80% before 2050. An interesting segment that could help to achieve this is older consumers, due to their growing numbers. There seems to be a lack of attention, in the research looking specifically at different age categories of older consumers’ green behaviour, and whether their level of greenness can be explained by their personality. Using Socioemotional Selectivity Theory and Time Perspective, the research presented here was designed to provide an exploratory analysis of how the green behaviour of older consumers is explained by their personality types. Based on the responses of 204 older consumers in the UK, our results find the openness personality trait to be positively linked to green behaviour, whilst the extraversion personality trait is negatively related to green behaviour. Although the level of green behaviour increased with older consumers’ age, this did not reach significance. 相似文献

Collaborative consumption is broadly defined as sharing, obtaining, and giving access to products and services through peer networks online. As it is expected to resolve the societal and environmental problems, quite a few studies investigated consumers’ motivations that lead to positive attitudes and intention for collaborative consumption. This paper aims to study the determinants that motivate participants to perceive a positive attitude towards collaborative consumption focusing on three salient traits of social capital (shared goal, social interaction tie, and norms of reciprocity). The study found that social capital exerts a more substantial influence on intrinsic motivation (enjoyment and sustainability) than extrinsic motivation (economic benefit). The study also found that different social capital traits display different effects on motivation. In particular, the shared goal was a key determinant of both intrinsic and extrinsic motivation. And all three motivations positively affect collaborative consumption attitudes. 相似文献

随着我国社会主义市场经济改革的不断深入,现有金融结构已不能适应经济发展。本文从金融结构调整的角度出发,对中国较发达地区,欠发达地区以及基于全国的数据进行面板回归。通过对实证结果的分析,得出金融结构调整对产业结构调整并不是简单线性关系的结论,金融结构调整应有合理的范围,当金融结构在其范围内变化时,能够促进经济的增长,当金融结构的调整超过合理范围时,金融功能的负作用会逐渐增强,当负作用积累到一定程度,会对经济的发展起到阻碍作用,我国各省份应根据自己的实际发展情况和自然禀赋,选择合适的金融结构和经济发展模式。 相似文献

John Joe Schlichtman Jason Patch 《International journal of urban and regional research》2014,38(4):1491-1508
Schlichtman and Patch suggest that there is an elephant sitting in the academic corner: while urbanists often use ‘gentrification’ as a pejorative term in formal and informal academic conversation, many urbanists are gentrifiers themselves. Even though urbanists have this firsthand experience with the process, this familiarity makes little impact on scholarly debate. There is, Schlichtman and Patch argue, an artificial distance in accounts of gentrification because researchers have not adequately examined their own relationship to the process. Utilizing a simple diagnostic tool that includes ten common aspects of gentrification, they compose two autoethnographic memoirs to begin this dialogue. 相似文献

适应节能形势发展的新变化,能耗监测的内涵也正在逐步延伸。实践表明,建立有效的能耗监测管控体系,对于提高能效、推进节能减排作用明显。近年来我国能耗监测管理得到了不同程度的改善,但在管理理念、制度安排、技术创新、资金支持等方面还存在着较多问题。利用信息技术,建立能耗在线实时监测管理体系,将成为未来能耗监测的发展目标。适应这种发展要求,我国需要在计量设备基础管理、能耗监测考核制度、监测机构设置和人员培训、资金渠道等方面进行不断创新。 相似文献

Constructing the culinary consumer: transformative and reflective processes in Italian cookbooks 总被引:1,自引:0,他引:1
Benedetta Cappellini 《Consumption Markets & Culture》2014,17(1):71-99
This paper explores how culinary texts operate in both performative and transformative senses in relation to wider societal norms of gender and cultural capital. As such, the paper explores changes to the way in which the culinary consumer is presented in British Italian cookbooks from 1954 to 2005. Across the period, we see a shift in the gendered representation of the culinary subject, from a housewife in the period 1954–1974, to a working mother from 1975 to 1986, and most recently as male or female cook from 1987 to 2005. We also see shifts in representation of cultural capital in these same periods from learning new cooking skills, to adapting existing cooking skills to displaying skills in shopping and product selection. In charting these changing discourses, we find that whilst reflecting wider culinary culture, these cookbooks also act in a transformative sense to promote (and indeed require) specific enactments of gender and cultural capital. 相似文献
