The goal of applying relational psychology and emotional intelligence to professional development for youth practitioners is to foster relationships in which both participants grow.     

Avatarculture: Narrative, power and identity in virtual world environments

Drawing on the work of Raymond Williams, this paper examines avatar culture through the interplay of emergent and residual forces. A dual process is at work in the formation of cultural identities in which the enabling conditions of virtual worlds are understood alongside and in relation to pre-existing off-line phenomenon. Avatar culture confirms structure for participants, especially in relation to gender and sexuality, whilst at the same time providing a reflexive space to break with pre-existing features of social identity. Virtual environments are thus microcosms of a grounded cultural materiality that is simultaneously improvised on and transformed. With regard to the distinctive aspects of avatar culture the paper focuses on issues of narrative, representation, censorship and power relations and their formation within virtual worlds. It discusses how virtual worlds incrementally acquire a peculiar power and meaning in the lives of participants. The paper discusses the flows of social interaction in virtual environments and how intermittence best describes how users participate and withdraw from different encounters. Avatar culture binds people together temporarily and loosely and then frees them up to relocate themselves elsewhere. In this context, virtual environments might be regarded as putting structure and power into movement. The ethnographic approach adopted helps peel back the residue of social structure to reveal a virtual agency with its emerging shells of avatar-derived affiliations, tensions and conflicts.     

DHM simulation in virtual environments: a case-study on control room design

This paper will present the workflow developed for the application of serious games in the design of complex cooperative work settings. The project was based on ergonomic studies and development of a control room among participative design process. Our main concerns were the 3D human virtual representation acquired from 3D scanning, human interaction, workspace layout and equipment designed considering ergonomics standards. Using Unity3D platform to design the virtual environment, the virtual human model can be controlled by users on dynamic scenario in order to evaluate the new work settings and simulate work activities. The results obtained showed that this virtual technology can drastically change the design process by improving the level of interaction between final users and, managers and human factors team.     

INFORMATION-CENTRED DESIGN: A methodology for designing virtual meeting DESIGN environments

Development of single-user computer applications has often been based on user-centred or task-centred design methodologies, with some success. These methodologies are also useful for guiding the development of multi-user CSCW applications whenever the basic characteristics of the users, or the type of tasks for which the system is being designed are identifiable. The effectiveness of these methodologies as a basis for the design of virtual meeting environments for supporting community-based activities, on the other hand, is rather limited. This is mainly due to the fact that for such systems it is not generally possible to identify the user or task requirements, as these vary considerably from one community to another, or even within the same community over a period of time. New methodologies need to be devised, or existing methodologies have to be modified, to direct the development of virtual environments for which the characteristics of the users or their activities are not known in advance. This paper introduces the concept of information-centred design. Information-centred design, though not fully devised yet, focuses on the identification of the type of information, as well as the way it is collected and utilized by the users of a virtual meeting environment. This pool of information, which plays an important role in facilitating interaction and communication between the members of a community, could be defined as their communal memory.     

On the effect of free vs. restricted interaction during the exploration of virtual environments

Exploration of a Virtual Environment (VE) might vary as well in applied technology as in the conceptual design. A conceptual difference of exploring style and navigation type relates to the degree of freedom a user possesses. It ranges from completely unrestricted to completely restricted navigation. To assess the impact of different exploration styles, an experiment was carried out. Four different styles were compared in a large-scale VE. The navigation of the participants was either free or restricted in various levels concerning motion and viewing direction. During the exploration, the participants memorized the location of flags, which represented special events at these locations. The participant's task was to memorize position and color of the flags. Subsequently, they marked the positions and colors of the flags in a map of the scene. The performance in this task was captured, as well as data about their amount of experienced simulator sickness and subjective workload. Additionally, balancing tests were administered to investigate in an objective measurement of simulator sickness. Each condition showed the same achievement in the memorizing task and the subjective workload. Furthermore, the measured high variance in simulator sickness symptoms overrode other effects. In the balancing tests a basic influence of exposure with VE was found. However, subsequent interviews with the participants showed that the personal impression of the efficiency of exploration method was highly individual. By finding and matching exploration methods to individual persons, benefit by using Virtual environments could be enhanced.     

The added value of virtual reality technology and force feedback for surgical training simulators

Laparoscopic surgery requires more specialized training of the surgeons than traditional open surgery. The Virtual Basic Laparoscopic Surgical Trainer (VBLaST) is being developed as a virtual version of the Fundamentals of Laparoscopic Skills (FLS) trainer. This study assessed the current haptic and virtual reality (VR) technology of a virtual peg transfer task of the VBLaST, based on the subjective preference of surgeons and their objective task performance measures. Twenty-one surgical residents, fellows and attendings performed a peg-transfer task in the FLS and the VBLaST. Each subject performed 10 trials on each simulator. Results showed that subjects performed significantly better on the FLS than on the VBLaST. Subjects showed a significant learning effect on both simulators, but with an accelerated improvement on the VBLaST. Even so, 81% of the subjects preferred the FLS over the VBLaST for surgical training which could be attributed to the novelty of the VR technology and existing deficiencies of the haptic interface. Despite the subjective preference for the physical simulator, the performance results indicate an added value of VR and haptics in surgical training, which is expected to be demonstrated in more surgically relevant tasks such as suturing and knot-tying.     

Metaphors we experiment with in multimodal ethnography

In this paper, we argue for a view of analysis as an embodied practice and review others’ testimonies of carrying out multimodal ethnography. This review suggests that metaphors are key for communicating what happens to us in the course of the research and our subsequent sense-making practices. We identify four metaphors for communicating data collection and analytic practices: composing, meandering, plundering and time travel. We then turn to our own multimodal fieldwork with children in middle childhood, to think about the experiences and emergent metaphors that shaped our practice on an international study looking at the relationship between childhood and public life. Children’s play was instructive in our own formation as multimodal ethnographers. We provide examples of the ways in which children recruited us into their play, the ways in which play taught us about what matters to children, and finally, how we took play into our own analytical practices.     

Implementation in generic environments

In this paper, we study implementation in “economic environments”. It is shown that there is a dense subset of the set of preference profiles such that given an arbitrary social choice function, f, and ε>0, there exists another social choice function, f _ε, within ε of f uniformly and implementable in Nash equilibrium on the dense subset.     

The elderly in rural environments

This paper provides a critical examination of the research available on the rural elderly in America. A detailed review of the many studies and topical areas investigated by rural gerontologists is not attempted. Rather, several ‘salient aspects’ of rurality (occupational, ecological and sociocultural) are identified as a basis for describing and explaining the status and experiences of older people in rural areas. The meaning of these dimensions as they relate to rural environments and the elderly is explored through both a general discussion and an application to two substantive issues — health status and life satisfaction. This examination illustrates the sizeable gaps that exist in what we currently know about the rural elderly and the problems/drawbacks of approaches traditionally used to study this topic. The paper concludes with a call for a more unified and conceptually based approach to future rural elderly research, that focuses on how and why the ‘salient aspects’ of rurality produce different circumstances and experiences for the elderly, and that emphasizes rural variation, not just ‘rural vs urban’ comparisons.     

Equitable opportunities in economic environments

 In this paper, we extend the axiomatic analysis of equitable opportunities developed in Kranich [6] from finite to continuous opportunity sets. This extended framework is amenable to economic applications. The main results establish conditions under which an ordinal ranking of profiles of opportunity sets can be represented by a cardinal advantage function which describes both the extent of inequality and the distribution of advantage among the agents.

降低职业经理人代理成本对策分析

知识经济时代，人力资本的重要性日益凸现。“经理人革命”之后，企业的所有权和控制权开始分离，更多的管理工作转移到了职业经理人手里。职业经理人作为企业管理高度专业化、职业化的产物，逐渐成为现代企业中具有决定性作用的特殊群体。但正因为存在着“专业化”的职业经理人，就出现了一种经理人由于相对优势而代表出资人行动的委托代理关系。所以，能否协调处理好货币资本的出资人和人力资本的职业经理人之间的关系，解决委托代理问题，降低代理成本，成为企业面临的一个战略问题。     

Working with women in secure environments

1. Women's adverse experiences as patients in secure and other mental health services appear to reflect sexism in wider social and historical contexts. 2. A Women's Service Development Group in a medium secure unit in the United Kingdom has made improvements in services for female patients, including an independent advocacy and befriending service, a Well-Woman Clinic, and other gender-sensitive activities. 3. In general, services were evaluated positively by women. Some dissatisfaction primarily was related to activities, issues concerning seclusion, and the lack of a day area for women only. 4. Women had mixed views about their contact with male staff and patients. Because of this, policies and services in this and related areas should account for individual needs.

Evidence of Skill and Strategy in Daily Fantasy Basketball

Using hand-collected data from DraftKings.com, a major daily fantasy sports website, we analyze draft selections of thousands of participants in daily fantasy basketball (DFB). In our study, the first thorough examination of DFB, we show that DFB is a game in which skill is necessary for success. Using econometric analysis, we find that winning participants utilize different strategies than losing participants; for example, winning participants more frequently select NBA rookies and international players. We also find that participants paying to enter more lineups in a given contest earn profits far more often than those entering few lineups, indicating that the number of lineups entered can serve as a proxy for skill. Additionally, we provide a thorough discussion of industry characteristics, prior literature, and gameplay, which should help readers familiarize themselves with this burgeoning fantasy sports variant. This study should further the literature on the contentious activity, which has been outlawed in many U.S. states and continues to elicit controversy.
