数字内容产品版权保护的演化博弈分析     

赵艳  王文举  倪渊 《图书情报工作》2019,63(2):43-51

[目的/意义]基于版权保护的演化博弈分析，有助于探究数字内容产品的原创主体对仿冒行为是否具有容忍度，以及不同仿冒水平下实施版权保护的策略选择，对规范数字内容产品市场主体行为具有一定指导意义。[方法/过程]首先借助演化博弈模型，分析原创主体与仿冒主体的利益演化过程，探究版权保护下原创主体对仿冒水平的容忍行为；然后通过细化博弈双方的利润函数模型，探究原创主体容忍度水平的决定因素。[结果/结论]原创主体对较小的仿冒水平存在一定的容忍度，对较高的仿冒水平零容忍。最大仿冒水平容忍度由仿冒交叉收益系数、收益模型常系数、产品研发成本系数和原创主体的产品研发努力水平倍数4个因素共同决定。  相似文献   

Breaking Down Barriers for Student Parents and Caregivers with Family-Friendly Library Spaces     

Anne Cooper Moore  Rebecca Croxton  Lindsey Sprague 《图书馆管理杂志》2020,60(3):215-234

Abstract

In 2016, J. Murrey Atkins Library at the University of North Carolina at Charlotte opened a reservable study room where student parents and caregivers can study with their children on campus. In 2018, the library opened a second family-friendly study room to meet the needs of our growing campus community. To inform the room design, the library conducted a mixed methods research study that included a user survey, an examination of room reservation and usage data, and one-on-one user interviews. This paper focuses on the user-centered design process used to inform the development of the second, family-friendly, library study room.  相似文献   

Identifying the combinations of motivations and emotions for creating satisfied users in SNSs: An fsQCA approach     

《International Journal of Information Management》2020

Social Networking Sites (SNSs) play an important role in our daily lives and the number of their users increases regularly. To understand how users can be satisfied in the complex digital environment of SNSs, this study examines how motivations and emotions combine with each other to explain high satisfaction. Users’ motivations comprise four attributes, entertainment, information, social-psychological, and convenience. Emotions are divided into their two main categories, that is positive and negative emotions. We draw on complexity and configuration theories, present a conceptual model along with propositions and perform a fuzzy-set qualitative comparative analysis (fsQCA). Through an empirically study with 582 SNSs users, we present eight combinations (configurations) of motivations and emotions that lead to high satisfaction, which highlight the role of high convenience, followed by entertainment and information motivations in being satisfied with SNSs. High satisfaction can be achieved both when positive and negative emotions are high and low, depending on how they combine users’ motivations. None of the factors are indispensable to explain high satisfaction on their own, instead they are insufficient but necessary parts of the causal combinations that explain high satisfaction. This study contributes in SNSs literature by extending current knowledge on how motivations and emotions combine to increase satisfaction, and by identifying specific patterns of users for whom these factors are important and influence greatly their satisfaction.  相似文献

Lutishoor Salisbury  Jeremy J. Smith  Abayomi Omotola Omolewu 《资料收集管理》2020,45(4):335-353

Abstract

This paper provides a methodology to study the characteristics of the research output from a university department. The faculty publications and their cited references over a 10-year period were used as the basis for this study to identify their publishing patterns and the types of material they are publishing; a core set of journals and other resources they are publishing in and citing over this period; the characteristics of the journals in which they publish and cite; the degree of openness of their publications and their citation advantage; and the age of resources that are referenced.  相似文献

复合氨基酸制剂对女子举重运动员运动能力的影响   总被引：3，自引：0，他引：3  

王琳  曹建民  覃小川  杨威林  甘运标 《北京体育大学学报》2004,27(9):1209-1210

为研究通过对服用以L-精氨酸为主要成分的复合氨基酸制剂对女子举重运动员运动能力的影响,对18名女子举重运动员分为试验组(服用复合氨基酸制剂组 9名)和对照组(服用安慰剂组 9名),测定他们在冬训前后的尿十项、血液睾酮、皮质醇、尿素氮、教练对运动员训练情况主观评价结果及训练效果.结果发现:实验组的KET、PRO、UBG及BLD水平在实验前后进行组内比较时没有明显变化(P>0.05);从组间比较的结果也可以看到,实验组的UBG、BLD水平有明显降低(P<0.05),但是PRO水平无论是组间,还是组内比较均未见显著性差异;实验组的运动成绩有了明显提高(P<0.05).提示以L-精氨酸为主要成分的复合氨基酸制剂对改善训练时运动员的身体状况有一定效果.  相似文献
