AbstractVirtual reality (VR) has emerged as a promising technological intervention for anxiety disorders. However, there are no existing standards and best practices to evaluate the effectiveness of environments to achieve their intervention goals. The purpose of this study was to develop a VR intervention for student veterans with social anxiety disorder and test feasibility utilizing a three-stage development model. The development of a therapeutic VR environment may benefit from an interdisciplinary collaboration of researchers from various fields of study. Utilizing three stages of prototyping with two virtual reality platforms, fully immersive video (n?=?6) and three-dimensional (3-D) immersive virtual reality (n?=?8), the research team designed an intervention for student veterans with social anxiety disorder, testing bio-reactivity of participants. Results of prototyping include user feedback validating increased stress levels and increased bio-reactivity specifically in galvanic skin response and heart rate elevation. Implications include the use of 360° video for prototyping 3-D virtual reality interventions. 相似文献

大学生国家认同意识关乎国家发展主体合力的生成与国家网络意识形态安全,更关系到人民对美好生活的向往和时代新人的使命担当。短视频解释性、场景化和感染力的特质优化了国家认同教育空间体验,创新了国家认同教育话语表达,开创了国家认同教育多元风格,重塑了国家认同教育作用圈层;但在资本逻辑、技术逻辑和商品逻辑的操控下,短视频行业跌入了“欲望泛化”“感性狂欢”和“物的迷恋”的怪圈,衍生出了消解大学生国家认同意识的隐性因子。面对潜伏性危机,高校必须分析和挖掘国家认同教育与短视频平台发展的内在契合点和价值共生点,强化内容认同、角色认同、思想认同和行为认同,促进国家认同意识的内化与外化。 相似文献

This article analyzes naturally occurring video‐recorded openings during which participants make the sensory social through the action of registering—calling joint attention to a selected, publicly perceivable referent so others shift their sensory attention to it. It examines sequence‐initial actions that register referents for which a participant is regarded as responsible. Findings demonstrate a systematic preference organization which observably guides when and how people initiate registering sequences sensitive to ownership of, and displayed stance toward, the target referent. Analysis shows how registering an owned referent achieves intersubjectivity and puts involved participants' face, affiliation, and social relationship on the line.

Crowdfunding entrepreneurs increasingly use videos to present their venture and themselves to potential investors. To do this effectively, they consciously or unconsciously use several impression management techniques. Based on human and automated (AI-based analysis) of technology-related videos, we determine which impression management techniques help crowdfunding creators to attract a higher number of backers and meet their financial targets. Our results indicate that self-presentation and exemplification techniques are positively associated with crowdfunding success, while intimidation is negatively related to crowdfunding success. Our findings show that automated analysis of videos using advanced AI can replace human coding since measures based on human coding become insignificant when AI-based measures are included in the analysis. This illustrates the insights companies can create through the large scale automated analysis of video content using AI, including outside of a crowdfunding context. 相似文献

Through a survey of more than 18,000 participants in a Chinese Massively Multiplayer Online Game (MMOG), this study examines how the size and diversity of Chinese gamers’ core networks vary by individuals’ sociodemographic, socioeconomic and game-related characteristics. It represents the first study focusing exclusively on the gamer population and one of the most recent examining personal networks in contemporary China, home to over 560 million Internet users. We found that Chinese gamers have notably larger and more diverse core networks than those of major studies. Coplaying patterns and attachment to the game community contributed significantly to network size and diversity. 相似文献

AbstractIn this essay, I suggest that artistic production provides valuable insights into the nature of the Canada-US border during the late-twentieth century when significant changes were occurring to dominant understandings of Canada in relation to North America. Focusing on the medium of video art, I trace the sustained engagement of Canadian contemporary artists to respond to and comment on the move towards continental integration through free trade. I contextualize my discussion in relation to trade developments that opened Canada’s border with the US, such as the 1989 implementation of the Canada-US Free Trade Agreement. This agreement, along with the later North American Free Trade Agreement, led to increasing continental integration at the end of the twentieth century, as well as hope for hemispheric integration with the subsequent negotiations towards the Free Trade Area of the Americas. With attention to works by Lisa Steele and Kim Tomczak, Eva Manly, and Clive Robertson, I foreground cultural contributions to redefining the Canada-US borderlands. Here, I chart the artists’ intention to echo narratives of the border’s porousness and address the power dynamics between the Canadian state and its trade partners. Examining themes of cultural imperialism, colonialism, and national identity, I point to the importance of cultural production in assessing the borderlands and, more broadly, histories of free trade in North America. 相似文献

采用演化博弈模型研究政策引导下的企业跨区域迁移行为,分析承接地政府和迁移企业的演化稳定策略(ESS).模型结果表明,迁移后获得持续增加的盈利空间、企业迁移成本、承接地政府的优惠政策以及迁出地和承接地环境规制力度的差别是影响企业迁移的重要因素;在不同的情境模式下,影响不同类型企业跨区域迁移行为的关键因素存在明显差异.在演化博弈分析的基础上,进而提出促进沿海企业向我国中西部地区有序迁移的政策建议. 相似文献

在实际中,消费者购买耐用品时均同时获得厂商提供的质保服务,由于产品质保服务影响着消费者的产品使用效用,因此耐用品定价、质保期和产品质保服务投入是影响厂商利润的主要因素。考虑双寡头市场环境下,建立微分博弈模型讨论单位产品质保服务投入和产品质保期对双寡头厂商均衡价格的影响。结论表明双寡头厂商的单位产品质保服务投入越高、质保期越长,均衡价格越高;但单位产品保服务投入与质保服务对消费者效用影响系数的关系影响着竞争对手在均衡价格的变化趋势;劣势的低质量厂商可以通过增加单位产品质保服务投入策略或延长质保期的策略实现在均衡下与高质量厂商以同等价格销售耐用品,但劣势厂商增加单位产品质保服务投入策略要优于延长质保期策略。最后,利用数值分析进一步验证了所得结论的有效性。 相似文献

在智能化和法治化的新时代,公共视频监控图像信息综合应用已成为社会治理社会化、法治化、智能化和专业化的重要方式。公共视频监控系统成为政府部门和社会组织保护公共安全以及公民人身、财产安全的技术项目。公共视频监控图像信息的技术手段和法律属性需要以立法形式加以规定。公共视频监控图像信息综合应用需要在权利保护的法律制度中进行,尤其是视频监控图像信息公开使用与信息安全、隐私权保护之间的法律制度设计。因此,公共视频监控图像信息的法律规制工作应对法律主体、基本原则、权利体系、法律监管、法律责任做出明确规定。 相似文献
