澳大利亚“Sanofi-Aventis”公司案若干法律问题探讨

关于药品说明书的著作权保护问题,我国理论界与实务界争论已久.药品说明书的独创性和合理使用问题,在澳大利亚司法实践中同样引起争议.有必要评介2011年澳大利亚 Sanofi-Aventis 公司案关于药品说明书独创性、默示许可方面的判决,分析Sanofi-Aventis公司案之得失,探索我国药品说明书著作权保护的合理路径.     

Designing effective corporate social advocacy campaigns using valence,arousal, and issue salience

Corporate social advocacy (CSA) is a growing communications practice that involves corporations taking a public stance on a controversial social issue. Some CSA campaigns have failed in the past (e.g., Pepsi’s 2017 Live for Now Moments Anthem video) by generating public backlash and damaging corporate reputation. To test how to design CSA campaigns that are beneficial for both the corporation and the advocacy issue, the current between-subjects experiment (N = 508) employed a 2 (issue salience: moderate vs. high) X 2 (valence: negative vs. positive) X 2 (arousal: moderate vs. high) factorial design to test the effects of salience, valence, and arousal on memory and four persuasion outcomes: company attitudes, purchase intentions, political participation intentions, and social media intentions, while also analyzing the mediation of information processing. Findings support prior research suggesting that negative valence increases persuasion in CSA contexts. A high-salience issue and high-arousal language increased political participation and social media intentions but had no effect on company attitudes or purchase intentions. Practical implications for CSA campaign designers highlight the persuasive potential of negative valence in CSA messages, and the utility of high-salience and high-arousal for political action and social media engagement.     

关于信息技术教师“三个问题”的思考

在教育信息化深入推进的背景下,考试招生制度的改革对信息技术学科建设和信息技术教师的发展具有“双重”重要影响。信息技术教师自身所固有的矛盾决定了该群体在基础教育教学信息化中的特殊职业角色和使命。本研究以“我是谁,我从哪里来,我到哪里去”为主线,对信息技术教师的内涵、结构现状、职业角色和职责范畴以及职业社会化等问题进行了尝试性“异位”思考,以期对改善信息技术教师的社会认同,促进信息技术教师专业发展具有一定的借鉴价值。     

“数据主义”滥觞下的新技术人文：智能时代算法传播的价值转型

智能传播时代,算法和数据技术成为社会基础设施和底层逻辑,并在广泛应用中带来数据主义思潮的盛行。数据主义的哲学渊源来自古希腊时期的毕达哥拉斯主义,主张将万事万物皆转化为算法可以计算的数据,从而根本上消解了人的存在价值和意义;人不再被视为具有独特性与丰富个性的主体,引发深刻的人文危机。基于技术哲学的思考发现,经典人文主义过于强调主客体的二元对立,不可避免陷入决定论的困境。技术与人并不是二元对立的主客体关系,而是具有同构性,且内在于人的主体性之中的存在方式。因此,体现和呈现人性、维护人的主体性和独特尊严成为智能时代算法技术应然的价值导向。但是,智能传播时代需要对传统人文主义进行超越与突破,构建以“人-技”和谐共生为旨归的新形式。     

Early Steps toward a National Energy Information System

The Energy Information Administration, which is the statistical arm of the Department of Energy, inherited many data-collection forms, files, and publications from predecessor agencies. There is a legislative mandate to establish a National Energy Information System (NEIS). This obligation demands attention to certain issues: (a) scope of NEIS, (b) methods of collection, (c) methods of storing information, (d) classification and indexing, (e) methods of access, and (f) reporting and publication. Early stages of dealing with most of these matters are underway.     

Fifth North Carolina serials conference: “ Serials at the speed of write—Coping,” Burlington,NC, April 4–5, 1996

Abstract

The Pacific Rim Library (PRL) is an initiative of the Pacific Rim Digital Library Association (PRDLA). The project began in 2006 using the OAI-PMH paradigm and now holds over 300,000 records harvested from OAI data provider libraries around the Pacific. PRL's goal is to enable the sharing of digital collections amongst PRDLA members and the world, but greater unexpected benefits have been discovered. Through mirroring their metadata, PRL increases the chance that their data will be discovered in Google and other general search engines. With its many disparate collections, PRL is not a repository for traditional information discovery and retrieval. Initially users will bounce from a Google hit to the PRL metadata record in Hong Kong and then begin an intensive search on the original site which hosts the full digital object, in Vancouver, Honolulu, Wuhan, Singapore, or other PRDLA member location.     

A bidimensional class of optimality criteria involving φp and characteristic criteria

A new biparametric class of criteria for Optimal Experimental Design generalizing the families of φ_p and Characteristic Criteria is presented. Some properties of the Characteristic Criteria are provided: in particular, differentiability, monotonicity and convexity. A statistical interpretation is also offered. Optimal designs with respect to Characteristic Criteria are obtained for polynomial and compartmental models and an extension of the Michaelis-Menten model. A thorough discussion for the trigonometric model is given. The computed optimal designs are shown to be quite efficient for A-, D- and D_s -optimality. Thus, some of them appear as a natural compromise between different optimality criteria. A simulation in multiple linear regression confirms the quality of Characteristic designs for discovering significant differences between parameters.
