Print Media Standardisation and Professionalism

The independence of the media under Ghana’s Fourth Republic is assessed from the perspective of standards and professionalism. Using a qualitative method, the study shows that unethical practices are evident in the print media landscape in Ghana, and argues that this can be traced to four major spheres: educational qualification, existence of several professional associations, a weak regulatory body and “money matters”. Overall, the study argues that legalities form a minimal part of the independence of the Ghanaian media but concerns about freedom seem to be self-inflicted by the very media practitioners through their actions and sometimes questionable reportage.     

Light-induced cracking and abrasion of inkjet prints: Damage and mitigation

This study is part of a larger research project at the Image Permanence Institute dedicated to digital print preservation issues – the Digital Print Preservation Portal (DP3). Previous DP3 studies determined that certain digital print types are prone to cracking and/or abrasion, and that factors such as low relative humidity, pollutants, and light increase the brittleness of the ink-receiving layer of some inkjet papers. The purpose of this investigation was to explore if light also increases the propensity of inkjet prints to abrade, and to examine the potential of framing glazings to mitigate light-induced physical damage (cracking and abrasion) by attenuating some portion of the UV spectrum. Inkjet papers and prints were subjected to xenon lighting (to simulate daylight through window glass) without glazing, or in sealed framing packages with plain framing glass (soda-lime) or UV filtering glass. Before and after light exposure, brittleness, and abrasion resistance were evaluated independently using two tests: ISO 18907 (Imaging materials – Photographic films and papers – Wedge test for brittleness) and a rub test utilizing a Sutherland® Rub Tester. In this study, exposure to light increased the cracking and/or abrasion tendency of some specimens. The use of UV filtering glass reduced this light-induced propensity in all cases. Plain glass protected all samples from at least one of these two types of surface damage, but was less effective than UV glass. Light-induced brittleness and sensitivity to abrasion were mostly, though not exclusively, caused by UV radiation. It was also seen that some prints may become brittle and/or prone to abrasion in the absence of image fade. Budgeting the amount of light these objects can be exposed to, protecting them from UV radiation, and handling prints with caution especially after exhibition, is essential in order to limit physical damage.     

TiNx-SiO2减反射膜的制备

This paper describes the preparation and properties of TiNx-SiO2 double-layered antireflective(AR) coatings that were applied with print process. The coating material was analyzed and TiNx was used instead of TiO2 as high refractive material. The influence of solution concentration on AR property was studied. The testing result shows that the coatings using print process are featured with excellent mechanical property and the AR property is comparable to American Southwall AR product. It is expected that the study would promote the industrialization progress in AR coatings.     

文字是幼儿图画书自主阅读中的关键信息吗?——来自幼儿在文字和主角上注视的眼动比较研究

文字意识是指有关文字形式和功能的内隐或外显意识,已有典型亲子阅读情境中的眼动研究发现儿童很少、甚至没有关注文字.研究收集了121名4-6岁儿童在图画书自主阅读情境中对文字和主角注视的眼动,分析结果证实了自主阅读情境中儿童比亲子阅读情境中更早、更多地注视文字.4-6岁儿童在主角上的注视随着年龄的增长在眼动指标上表现为不断优化,在文字上的注视随着年龄的增长不断发展,但还未达到成熟水平.5-6岁是儿童图画书自主阅读过程中文字视觉注视水平发展的重要时期.儿童的文字视觉注视能力的发展存在性别差异.

Hot-Heads,Gentlemen and the Liberties of Tradesmen

Abstract

Over the summer and autumn of 1739 Philadelphia’s two newspapers published competing versions of a hearing in the Pennsylvania assembly that was described as the ‘Affair of the Tanners’. What began as a minor property dispute in the colonial assembly became, with the aid of the local press, a citywide paper war for the support of the urban populace. This article argues the affair provides unique evidence for competing conceptions of the common good in the eighteenth-century colonial city, and was an expression of conflict with deep roots in Philadelphia’s history. The affair also shows how the medium of print could reflect both transatlantic cultural processes as well as distinctly local grievances, as a group of prosperous city artisans and their opponents utilized the city’s newspapers to articulate competing commonwealth ideologies.     

男子武术套路运动员皮纹特征的研究

采用双手皮纹测试观察法，对40名优秀男子武术套路运动员的指端纹型、各类指端纹型频率、指端纹型对应格局、指端嵴纹总数等7个皮纹单项指标进行调查和统计分析。结果发现，优秀男子武术套路运动员在许多单项指标上，有别于普通人群和其它项目的运动员。

平面广告图像叙事分析简

平面广告中的图像存在于特定的语境中,由于特别的构图设计,这类图像完成了“空间性”向“时间性”跃进,可以有效地讲述“微型故事”.平面广告叙事呈现出图像中心化的趋势,不论叙事视点选择多么巧妙,这类图像叙事大都无法掩盖其商业逻辑.
