浅谈纤维艺术与装饰织物

纤维艺术对于大多数人来讲是一个陌生的名词,但是纤维艺术与人类的生活是息息相关的。在我们的生活中运用纤维制成的物品不胜枚举,特别是随着人们生活水平的提高,大量纤维装饰织品走入人们的生活,成为美化环境陶冶情趣的艺术品。纤维作为人类生活生产的基本原材料自古至今被广泛用于装饰性纺织品制造业,丝毛棉麻等天然动植物纤维以及一些化学的有机合成纤维,以其各自独有的质地魅力通过编结缠绕等加工工艺和精心的设计制成漂亮的编织品和装置软体,成为了大众所喜爱的装饰织物。

高性能钢纤维混凝土在超低梁的应用

32m超低高度梁是我国铁路梁施工常用梁体结构。采用后张法预应力施工,高强混凝土的抗裂性能和抗应变能力往往达不到技术要求,梁体抗裂安全系数差。本文提出采用含钢纤维和矿物外加剂DBF的混凝土浇筑铁路梁,来改善混凝土脆性缺陷,提高其抗裂、抗拉性能,从而有效避免了高强混凝土在承受极限应力时开裂,有效确保了32m超低高度梁制造技术可靠,经济可行。     

Pious populists at the gate

In this paper, I evaluate the economic track record of the Justice and Development Party (AKP) in Turkey, using the synthetic control method (SCM). This methodology compares the post-AKP development trajectory of Turkey with that of a weighted combination of similar but untreated countries. The SCM is particularly useful in this setting as it allows construction of a synthetic control to Turkey that replicates the pre-AKP development dynamics. I find that Turkey under AKP grew no faster in terms of GDP per capita when compared with a synthetic counterpart from a wide pool of other countries. Restricting the pool of control units to only include Muslim countries shows Turkey growing slower than its Muslim counterparts. Moreover, analysis of post-crisis recovery periods shows Turkey growing no faster than comparable post-crisis cases across time. However, expanding the outcome set to health and education reveals large positive differences in both infant and maternal mortality as well as university enrolment, consistent with stated AKP policies to improve access to health and education sectors for the relatively poorer segments of the population. Nonetheless, increased access in these fields is not matched by improved labour market access, as both labour force participation as well as unemployment have deteriorated, and especially so for women. As for measures of institutions, I fail to find any durable positive differences in measures related to democracy or human rights early on during the post-intervention period, and in several instances there is evidence of significant declines over the long run. A particularly salient feature of the AKP's reign is reduced political power of the military, consistent with the military in Turkey receiving lower economic rents than its synthetic counterpart during AKP's reign.     

房产税对企业投资行为的影响——来自上海和重庆的经验分析

本文以上海和重庆房产税试点改革为重点,在分析房产税改革对企业投资影响机理的基础上,基于2006~2016年度35个大中城市的面板数据,采用合成控制法实证分析房产税改革对企业投资的影响效应,结合排序法与双重差分法进行稳健性检验。结果发现,相比房产税改革试点前,地方企业投资出现不同程度的提升。这表明地方政府可注重研究本地企业投资现状,在中央的部署下,通过适度调整房产税政策来引导企业投资,使得投资结构与地区经济结构相适应,实现地区经济高质量持续发展。     

The signalling effect of eco-labels in modern coastal tourism

As the demand for environmentally sustainable tourism grows, eco-labels are becoming increasingly popular as a signal of environmental quality. However, the existence of a causal link between awarding a seaside eco-label and the increase in tourism flows is still under discussion in the literature. In this article, we gauge the signalling impact of a specific eco-label, the Blue Flag award, using detailed data on tourism flows to seaside Italian destinations during the period 2008–2012. We adopt a recent econometric modelling strategy – the synthetic control method – in shaping estimation results and testing the sensitivity and robustness of our results. We find that being awarded the Blue Flag increases the flow of domestic tourists for up to three seasons after assignment. However, we find no effect for the flow of international tourists. Investigating the mechanisms driving the results, we find that the award of a Blue Flag only positively affects the flow of domestic tourists when it is used as a driver of organisation, coordination and integrated management of the tourism supply.     

碳纤维加固桥梁技术实用研究

随着我国经济的不断发展,对公路、铁路运输的要求的也越来越高,而这其中,桥梁技术是非常重要的环节。我国的桥梁技术自上个世纪八十年代以来,发展较为迅速,但是对桥梁的保养、维护、维修、加固技术的发展则比较缓慢,进度也相对滞后,这是目前我国公路桥梁发展的主要技术缺陷。本文重要探讨与研究如何使用碳纤维加固技术,使桥梁施工更加稳固。
