众筹教育通过打造并完善教育资源共享平台,推动教育资源的虚拟重组、均衡发展,实现跨区域教育的协同发展,有助于实现知识增值的目标。众筹教育所具备的创意性筹资、柔性化生产、互动化交流、区域化共享等特征使其与当下的高校美育选修课教育体制改革的需求高度契合。从实现路径来看,众筹教育介入高校美育选修课改革可以从校内模拟众筹、区域内课程共享、完善教育资源共享平台3个层面逐步铺开,形成高校美育选修课线上与线下互动发展的新模式,为推动我国教育体制改革困局的破解提供思路。  相似文献

与以往单纯以内部网络口碑、相互独立的内部和外部网络口碑为研究对象,分析网络口碑与在线销售的关系不同。基于评论环境理论,采用分层贝叶斯模型,以当当网、京东、亚马逊和豆瓣网为数据搜集对象,在充分考虑网络口碑异质性及其来源多元化的条件下,结合外部网络口碑平台信息提供的特点,在进一步引入免费试样因素的基础上,对内外部网络口碑与在线销售的动态交互作用进行研究。结果发现:在异质性网络平台并存且效价差异较小的情境下,效价不再是影响在线销售的关键,而内部网络口碑数量、数量信息熵才是影响在线销售的关键,反过来在线销售也刺激了网络口碑数量的提升。虽然外部网络口碑的存在削弱了这一环形机制的积极影响,但免费试样可有效削弱该负向调节机制。  相似文献

This paper contributes to the discussion on deliberative, direct democracy and volunteer mobilization in the Internet era by analyzing the vote participation levels of Wikipedia volunteer editors (Wikipedians). On 18th January 2012 in the ‘first Internet strike’ against the American ‘Stop Online Piracy Act' legislation, over two thousand Wikipedians took part in the vote concerning whether their site should undertake a protest action, with vast majority expressing support for this action. However, the vote participants formed only a tiny fraction of the total number of Wikipedians who number in millions. Although Wikipedia can be seen as an open, democratic forum practicing deliberative, direct democracy, the process of voting on Wikipedia is significantly influenced by participation inequality, with a majority of the vote participation coming from a small group of most active contributors – an effective oligarchy. This paper discusses the intricate dynamics between Wikipedia egalitarian ethos and the creed to discuss project matters deliberately on one hand and the conspicuous lack of promotion and advertisement stemming from a rule against ‘canvassing’ and an overall skepticism regarding the status of majority votes. While voters' passivity and lack of interest play a major role, as expected, another factor emerges as a significant factor responsible for the low levels of participation: an inefficient information distribution system, as the vast majority of Wikipedians were not aware of the ongoing discussions and the vote itself until after their conclusion.  相似文献

As the civil law expression of internet plus transactions, the legal relations in online trading platform transactions constitute a complex aggregate of legal relationships composed of groups of legal relations. Specifically, they consist of three basic interlinked legal relationships: Contract relations for online trading platform services between the platform provider and the seller or service provider, and between the platform provider and the consumer. This includes the sales or service contract relations between the triad of the seller, the service provider and the consumer. These relations contain five kinds of major content, viz., the provision of transaction space, the publishing of transaction information, price escrow payment, distribution and delivery of the commodity, and transaction credit evaluation. They involve three forms of supplementary legal relations: the supplementary contract relationship between the platform provider and a third party payment institution; between the seller and third party credit reporting agency; and between the seller and a logistics enterprise. The three forms of supplementary contractual legal relations are set up to act on the major contents of the basic legal relationships in online transactions. On the basis of the online trading platform service contract relationships between the platform provider and the triad of the seller, the service provider and the consumer, the flow of the above- mentioned legal relations centers on the contract of sales or service set up between the seller, the service provider and the consumer to accomplish the aim of the online transaction, meet social needs and boost economic development.  相似文献

ABSTRACT

This paper explores the difference in the online economic activities of people with and without disabilities in Korea. We conducted a multiple regression analysis to investigate the impact of socioeconomic characteristics, internet access, and internet skills on online economic activities. Our sample, based on a 2016 dataset that included 1554 people with disabilities and 6004 people without disabilities, was developed using quota sampling based on gender, age, and residence. We determined that individuals with disabilities were more likely to engage in online economic activities if they had higher levels of education, lived in urban areas, were employed, or had greater internet skills. Individuals without disabilities were more likely to engage in online economic activities if they were women, had higher levels of education, were employed, lived in a two-generation or more household, or had greater internet skills. For both people with and without disabilities, the level of education, employment status, and internet skills positively contribute to online economic activites. We also determined that education level, participation in economic activity, living in a two-generation or more household, and internet skills had a statistically significant influence on online economic activity for people both with and without disabilities. These results highlight the importance of education and internet training for people with disabilities, as well as social support systems that help them learn to use the internet in diverse ways through both formal and informal networks. The study also underscores the importance of information and communications technology that adequately addresses people’s needs.  相似文献

This qualitative content analysis of online documents compiled from the North American Animal Liberation Front (ALF), Earth Liberation Kollective (ELK) and Grassroots Ontario Animal Liberation (GOAL) network websites and Facebook pages explores how activism within the Radical Animal Liberation Movement (RALM) intersects with other social movements. While most literature to date traces the RALM’s (dis)junctures with other forms of social justice activism through analyses of their broad ideological assumptions, or the views of renowned RALM scholars, this research provides authentic insights into the voices of Canadian, American and Mexican activists as they are represented in documents they author themselves. Like activists in anarchistic, anti-capitalist, immigrant rights, Indigenous, prison abolition, prisoner support and radical feminist movements, those in the RALM critique capitalism, colonialism, hierarchy, racism, sexism, state power and the prison industrial complex. Our research calls into question the existing narratives that depict the RALM as an extremist, single-issue movement oblivious to all other forms of social inequality, injustice, marginalization and oppression. Rather, RALM activists are building alliances with other radical social movements to achieve the common goal of ending both human and animal suffering and exploitation.  相似文献

The mean residual life measures the expected remaining life of a subject who has survived up to a particular time. When survival time distribution is highly skewed or heavy tailed, the restricted mean residual life must be considered. In this paper, we propose an additive–multiplicative restricted mean residual life model to study the association between the restricted mean residual life function and potential regression covariates in the presence of right censoring. This model extends the proportional mean residual life model using an additive model as its covariate dependent baseline. For the suggested model, some covariate effects are allowed to be time‐varying. To estimate the model parameters, martingale estimating equations are developed, and the large sample properties of the resulting estimators are established. In addition, to assess the adequacy of the model, we investigate a goodness of fit test that is asymptotically justified. The proposed methodology is evaluated via simulation studies and further applied to a kidney cancer data set collected from a clinical trial.  相似文献

在英语并列疑问句中,存在着ATB(Across the Board)移位现象。汉语作为Wh in situ的语言,不允许疑问词提升。但是通过对实际的语料分析发现,在汉语某些宾语前置的话题结构中,同样存在着ATB式移位。文章通过分析这些结构的句法特征和生成机制,证明了在汉语中同样存在着ATB移位现象,并通过对比不同语言中话题化结构的特点,进而证明了ATB移位具有跨语言的普遍特性。  相似文献
