Internet Technology and Social Capital:How the Internet Affects Seniors’ Social Capital and Wellbeing

Although it is increasingly obvious that the Internet is changing human life; the details of this change are not yet clear. A major debate in current literature involves the capacity of the Internet to enhance social capital and wellbeing in old age. In this regard, the present study attempts to investigate the relationships between Internet use and older people’s social capital and wellbeing. An online survey was conducted at the University of Sydney. 222 seniors responded to the survey. The measures used included a wide range of instruments related to the Internet use, social capital and wellbeing. Respondents used the Internet for various purposes, including seeking information, entertainment, commerce, communication, and finding new people. The main findings of the study were that the relationships between Internet use, social capital and wellbeing is a complex construct and the Internet has different effects on social capital and wellbeing resulting from different use of this technology. The study results revealed that the Internet is a 2‐edged sword with the ability to both harm and help. According to the findings of this study, using the Internet can be helpful for older adults if they are aware how they use it.

基于Jack的老年人辅助座椅需求研究及仿真分析

随着年龄的增长,身体状况也在不断发生变化。进入老年阶段后,身体的各项机能显著衰弱,无法正常地完成一些常规的动作,在使用一些常规的工具的时候,为了达到更好的效果,不得不使用某些具有辅助功能的装置。本文通过对老年人身体参数和肌力变化的研究,在深入调研的基础上确定老年人对辅助座椅的功能需求和客观需求。针对功能需求建立辅助座椅的基础模型,通过Jack软件对老年人辅助座椅进行人机工程学仿真,并基于老年人的客观需求对舒适度、可视域、受力和可达域等方面进行分析。分析结果表明辅助座椅人机工程学性能较为良好,但是某些方面仍需要进行改进。     

Teenagers in social virtual worlds: Continuous use and purchasing behavior in Habbo Hotel

Social virtual worlds (SVWs) have become important environments for social interaction. At the same time, the supply and demand of virtual goods and services is rapidly increasing. For SVWs to be economically sustainable, retaining existing users and turning them into consumers are paramount challenges. This requires an understanding of the underlying reasons why users continuously engage in SVWs and purchase virtual items. This study builds upon Technology Acceptance Model, motivational model and theory of network externalities to examine continuous usage and purchase intention and it empirically tests the model with data collected from 2481 Habbo users. The results reveal a strong relationship between continuous usage and purchasing. Further, the results demonstrate the importance of the presence of other users in predicting the purchase behavior in the SVW. Continuous SVW usage in turn is predicted directly by perceived enjoyment and usefulness while the effect of attitude is marginal. Finally, perceived network externalities exert a significant influence of perceived enjoyment and usefulness of the SVW but do not have a direct effect on the continuous usage.     

User goals in social virtual worlds: A means-end chain approach

The purpose of this study is twofold: first, to investigate user goals in social virtual worlds; second, to introduce a methodological alternative (i.e., a means-end chain approach) for analyzing user goals in cyberspaces. The data were acquired from a web survey, and were analyzed by means-end chain analysis (MECA), which produces users’ goal structure in reference to a hierarchical system of interrelated goals (Olson & Reynolds, 1983). The results show that people come to social virtual worlds to satisfy their social and hedonic needs, and to escape from real world constraints, as do virtual community members and virtual gamers; they also pursue unique activities, such as creating virtual objects and selling them. On the other hand, by clarifying relations among users’ goals, MECA provides a richer explanation for user goals than prior research which only offers separate user goals for cyberspace users without explanation of relationship among goals.     

Emergence of Collective Behavior in Evolving Populations of Flying Agents

We demonstrate the emergence of collective behavior in two evolutionary computation systems, one an evolutionary extension of a classic (highly constrained) flocking algorithm and the other a relatively un-constrained system in which the behavior of agents is governed by evolved computer programs. The first system demonstrates the evolution of a form of multicellular organization, while the second demonstrates the evolution of a form of altruistic food sharing. In this article we describe both systems in detail, document the emergence of collective behavior, and argue that these systems present new opportunities for the study of group dynamics in an evolutionary context. We also provide a brief overview of the breve simulation environment in which the systems were produced, and of breve’s facilities for the rapid, exploratory development of visualization strategies for artificial life.     

Virtual rights? Property in online game objects and characters

The new industry of Massively Multi-Player Online Role-Playing Games (MMORPGs) brings together two sets of fictions: the interactive stories of shared computer games and the legal devices of intellectual property. In these virtual worlds, scarcity need not exist, but players tend to prefer the competition it creates. This leads to the development of property rights within the game world and players trading real money for virtual objects, ‘land’ and characters. This new phenomenon brings with it familiar legal problems such as theft, fraud and ownership disputes. Game creators also challenge the right of the players to claim ownership outside the game world. The volume and value of the items traded make real money trading an important area of current interest for intellectual property lawyers. Something is being traded, but does it fit neatly into existing conceptions of property rights and who owns it? Analysing the novel problems that result from various theoretical perspectives (utilitarianism, labour-desert theory and personality theory) leads to the conclusion that with time, we will see the development of property rights for players in online games. This connects with a growing understanding that the traditional conception of copyright law dealing with creative work generated by the solitary author is becoming less appropriate in the new creative spaces that information and communications technology brings, where individuals are both consumer and producer. In virtual worlds, new forms of intellectual property, and perhaps even new rights, are taking shape.     

The role of message-sequences in the sustainability of an online support community for older people

This article presents an investigation of an online support community for older people, analyzing a data-set of messages posted over the period of six years. We studied messages that are related to each other which we call "message-sequences". We investigated the content of message-sequences and linked our findings to the level of activity of the online support community over time. We show how certain sequences of messages within the online community are related to the level of activity thus providing valuable insight into the role of message-sequences in sustaining online support communities for older people. We conclude that the mutual exchange of personal information and receiving support after talking about personal problems are basic components for the sustainability of the online community, whereas conversations that go off the topic of the online community seem to be related to a decrease in the level of activity.     

Support and information needs of older and disabled older people in the UK

The aim of this study was to determine the support and information needs of older and disabled older people in the UK. Following an initial literature survey, an examination of data on enquiries made by older people to information providers, and a series of focus groups, a questionnaire was developed for a nationwide survey. Over 1630 questionnaires were completed by disabled older clients of Day Care Centres and less frail older members of social clubs. Findings showed that there is a serious shortfall in the number of older people getting the practical support that they need, and the information that enables access to this support, compared to the number that actually need help. Substantial percentages of the survey respondents experienced difficulty with everyday tasks and with accessing the information they needed. Implications for formal sources of support and information are discussed.
