基于UDK的数字校园虚拟现实引擎关键技术的研究

虚拟数字化校园漫游系统是数字化校园建设计划的核心平台。本文首先对目前主流的虚拟可视化开发工具作了介绍,并结合当今最流行的游戏引擎UDK（Unreal Development Kit）和三维设计软件3ds Max的虚拟现实关键技术问题进行了研究,以无锡城市职业技术学院校区为原型,设计并实现了将虚拟现实引擎作为三维动态交互立体数字校园开发平台的核心构件,着重对引擎实现过程中的3ds模型导入进行了解析,包含了材质编辑技术、物理碰撞技术及碰撞检测技术等关键技术。结果表明,上述技术的通用性在虚拟现实引擎中可见一斑,极大地提高了引擎的实用性和执行效率。     

Evolution of the practices of human resource management in France towards a strategic model: rhetoric or reality?

This article analyses the evolution of the human resources management in France. The study attempts to understand the transformation of administrative practices of HRM towards strategic practices of HRM (SHRM) in the French context. It also shows the factors responsible for this change. The results of this study support the development in France of SHRM and the regression of administrative practices of HRM, although a third hybrid model of HRM seems to appear between both practices. This tendency towards SHRM is accentuated in large firms, quoted on the stock exchange, in services and finance sectors with international activities. This study confirms that the SHRM in France is reality rather than rhetoric.     

我国能源就地转化的目的研究

能源就地转化的目的是资源地实施能源就地转化意欲达到的结果。以我国能源就地转化的历史分期为标准,能源就地转化的目的可分为初始目的、眼前目的和长远目的。能源就地转化初始目的的实现需资源地加快能源外送通道建设。能源就地转化眼前目的的实现需资源地处理好能源外送与留存、初级能源售卖与产能过剩的关系和加强资源地的能源消纳能力。能源就地转化长远目的的实现需资源地解决好能源的眼前利益索取与长远利益保护的关系。     

从异化劳动到劳动的二重性:马克思的人学探索

异化劳动学说中工人同自己的类本质相异化蕴含着工人在资本主义社会中的双重存在——这一思想在《德意志意识形态》中被马克思进一步表述为"现实的人"的双重存在:一方面是作为个体的"现实的人"的存在;另一方面是作为共同体的"现实的人"的存在。"现实的人"的双重存在产生了劳动的二重性,劳动的二重性则形成了商品的二重性:作为个体的"现实的人"的具体劳动形成商品的使用价值;作为共同体的"现实的人"的抽象劳动则形成商品的价值。以此为理论基石,马克思写成其政治经济学批判的巨著《资本论》。     

关于我国贸易战略调整的探讨

随着日益扩大的出口,以及外汇储备的增长,我国的改革开放已经到了一个新的阶段．其中对外贸易战略正经历调整,即从出口至上转向进出口平衡发展。贸易战略调整。需在贸易发展的理论背景下及经济发展的现实基础上,确定特定阶段下的贸易战略调整重点。关于我国贸易战略及其调整问题,国内学者多有争论,本文在不同学者观点基础上进行梳理和探讨。     

论虚拟仿真技术与群体支持系统在工程管理中联合应用

工程施工计划是一项复杂的工作，不断增长的复杂因素决定了工程管理人员需要采取新的、从未被用过、检测过的工程施工方法。缺乏便于工程策划人员进行评估和确认施工计划是否合理的工具，会在工程施工阶段造成许多重复性工作，造成成本浪费。虚拟现实技术为解决上述问题提供了一个很好的方法，会生成虚拟环境，允许项目决策人员在施工之前合理优化和选择施工方案，资源优化，降低成本，从而获得更好的投资效益。利用群体支持系统建立与工程施工计划相呼应的模型，工程数据作为其处理问题与人机交互的依据，辅助人员决策，进行项目的预算和分析，提高工程项目的价值管理。     

The virtual takeover: The influence of virtual reality on consumption

Looking to current trends, this paper explores the influence of Virtual Reality (VR) on consumption. Specifically, we focus on the influence that VR has on consumer spending by suggesting that identities created in VR will influence consumption behaviour in the real world. While other forms of technology allow consumers to create alternative identities, we suggest that the unique aspects of VR, bolstered by forthcoming advances, will make identities created in VR relatively more self-important and more salient in real world consumption. We also propose implications for marketing research and practice.     

Virtual reality tourism experiences: Addiction and isolation

This qualitative research note reports two neglected themes in research on virtual reality tourism experiences, i.e. its potentially addictive nature and temporary sense of isolation. Existing work on virtual reality tourism experiences has applied existing knowledge and theories and has solely tested how VR applications can positively mediate or moderate the tourist experience. This study adopted an inductive approach, analyzing contents of reviews and blogs, and consequently uncovered a temporary sense of isolation and the addictive nature of virtual reality as hidden themes within virtual reality tourism experiences. We stress the importance of further work on addiction and a sense of isolation in terms of their nature, role, and effects.     

Effects of perceived interactivity of augmented reality on consumer responses: A mental imagery perspective

As the use of technological features is becoming more common in digital retailing, retailers have adopted augmented reality (AR) solutions to help consumers browse their products. This study examines dimensions of perceived interactivity after experiencing shopping with AR and investigates the relationships between perceived interactivity and mental imagery and between mental imagery and other consumer responses in a mobile shopping context. A total of 302 female online consumers in South Korea participated in a survey. After shopping cosmetic products with the AR function in a mobile app, participants completed the questionnaire. The findings reveal that the controllability and playfulness dimensions of perceived interactivity influence mental imagery, which, in turn, affects consumers' attitudes toward a product and their behavioral intentions. The relationship between perceived interactivity and mental imagery differs based on an individual's involvement level. These results provide practical insights for digital retailers in creating effective mobile shopping environments.     

Technology as a tool to rebuild heritage sites: the second life of the Abbey of Cluny

Technology has made changes in communication, lifestyle, and cultures, creating a new challenge to heritage sites. Technology can be the answer to connecting with local communities and tourists, reducing the gap between people and their inheritance, making it more understandable, creating awareness and value and eliminating time and space limitations. It can be used to communicate, interpret, teach, analyze, and make heritage accessible. And it can also be applied to make virtual reconstructions of what no longer exists. This paper analyzes the effect of technology at a heritage site, using the Abbey of Cluny as a case. This Abbey is a monument in France due to its importance during the Middle Ages as the monastic capital of Europe. Today, there are only a few traces of what the Maior Ecclesia used to be. New technologies were applied to rebuild what was destroyed with time using augmented reality and 3D reconstruction. Qualitative methods were used to describe what effects in visitors and promotion of the site were observable.
