Women in Illusion： An Analysis of Women Characters in The Glass Menagerie

The paper tries to analyze women characters in Tennessee Williams' Drama The Glass Menagerie.Laura and Amanda,the daughter and the mother,represent the delicate and fragile southern female images.They both feel desper-ate about the reality and retreat to their own world of illusions.Laura,because of her crippled body,cannot face the or-dinary problems of life and withdraws into the world of glass animals.Amanda Wingfield is unable to face the harsh struggle for survival,constantly retreats to her past memories.

旧南方文化桎梏下的认同危机——田纳西·威廉斯《玻璃动物园》中阿曼达的人物形象分析

田纳西·威廉斯《玻璃动物园》再现了美国旧式南方家庭在经济大萧条下的悲惨境遇。处于社会变迁和新旧南方文化交替之际的剧中人物阿曼达是典型的旧式南方淑女。文章通过分析阿曼达的身份认同危机以及认同失败的根本原因,认为:阿曼达未能直面残酷现实并合理地调适自己,对自我位置缺乏清醒的认识,无力改变现实生活的悲惨境遇,从而迷失于没落的旧南方文化。     

Improvement of enamel bond strengths for conventional and resin-modified glass ionomers: acid-etching vs. conditioning

Objective:This study deals with the effect of phosphoric acid etching and conditioning on enamel micro-tensile bond strengths(μTBSs)of conventional and resin-modified glass ionomer cements(GICs/RMGICs).Methods:Forty-eight bovine incisors were prepared into rectangular blocks.Highly-polished labial enamel surfaces were either acid-etched,conditioned with liquids of cements,or not further treated(control).Subsequently,two matching pre-treated enamel surfaces were cemented together with one of four cements[two GICs:Fuji I(GC),Ketac Cem Easymix(3M ESPE);two RMGICs:Fuji Plus(GC),RelyX Luting(3M ESPE)]in preparation forμTBS tests.Pre-treated enamel surfaces and cement-enamel interfaces were analyzed by scanning electron microscopy(SEM).Results:Phosphoric acid etching significantly increased the enamelμTBS of GICs/RMGICs.Conditioning with the liquids of the cements produced significantly weaker or equivalent enamelμTBS compared to the control.Regardless of etching,RMGICs yielded stronger enamelμTBS than GICs.A visible hybrid layer was found at certain enamelcement interfaces of the etched enamels.Conclusions:Phosphoric acid etching significantly increased the enamelμTBSs of GICs/RMGICs.Phosphoric acid etching should be recommended to etch the enamel margins before the cementation of the prostheses such as inlays and onlays,using GICs/RMGICs to improve the bond strengths.RMGICs provided stronger enamel bond strength than GICs and conditioning did not increase enamel bond strength.

巴塞尔姆小说创作:荒谬中的真实——以短篇小说《玻璃山》为例

唐纳德·巴塞尔姆是美国最有争议的作家之一,也是后现代主义代表人物。他的小说内容破碎、中心离散、反体裁、反情节,因而常被以“荒谬”论之,但在荒谬表象下是巴塞尔姆小说反映后现代社会真实现实的本质。     

When Glass and Metal Corrode Together,V: Sodium Copper Formate

A sodium copper formate, first described in 2002, can also form on copper alloys with sodium originating from soda glass hydrolysis. The frequent occurrence (50% of 250 cases of glass-induced metal corrosion) is due to the presence of formaldehyde emissions in storage and its direct reaction to formate in the alkaline surface films. The compound can be produced without the presence of acetate when chalconatronite or metal coupons immersed in soda solution are exposed to formaldehyde vapours. The crystal structure, derived from X-ray powder diffraction, yielded the sum formula Cu₄Na₄O(HCOO)₈(OH)₂·4H₂O. Except for the absence of acetate in the structure, this is in good agreement with the 2002 publication. To assess which kind of combined glass/metal objects are affected, a number of large museum collections were surveyed. Sodium copper formate was detected as a corrosion product using mainly micro-Raman spectroscopy, for instance, on 18 painted Limoges enamels, eight glass vessels with metal mountings, glass beads on metal wire from 11 bridal crowns, nine Christmas tree balls with wire decoration, 40 pieces of jewellery with glass gems, three daguerreotypes, and one miniature with cover glasses.     

玻璃幕墙施工的质量控制

玻璃幕墙具有光洁、明快、挺拔、轻质、高强等特点,同时它将建筑物外围护墙的防风、遮雨、保温、隔热、防噪音、防空气渗透等使用功能与建筑装饰功能有效地融合为一体,并作为结构的一部分,直接承受荷载和地震作用.但其构造复杂,施工技术要求高,专业性强.因此,对玻璃幕墙工程的质量控制十分重要.本文通过对华南某医学院图书馆玻璃幕墙施工工程为例,根据国家有关规范,从设计、选材、制作及施工等方面分析了玻璃幕墙工程的质量控制要点.     

Does the expansion of higher education reduce gender gaps in the labor market? Evidence from a natural experiment

In 2005 Chilean congress approved a bill that established a new funding tool for higher education funding through a "private system" of student loans (named CAE). The system aimed to support higher education inclusion among students with academic merits overcoming the lack of resources for ensuring access. Politicians have referred to this reform in higher education funding as a critical factor for expanding higher education enrollment. By its immediate results, it is a great strategy to cope with inequality and social mobility issues. However, there is little empirical evidence about labor market variables' overall effects, such as gender discrimination. This work attempts to estimate the new instrument's impact on the three standard measures of gender labor discrimination: labor participation, the gender wage gap, and the glass ceiling. The empirical strategy uses a difference-in-difference approach to provide estimates. The results indicate that the CAE policy changed women's labor market participation and contributed to close the gender pay gap in the labor market. However, the glass ceiling increased in the entire labor market, but not in the white-collar job market in specific.
