    Get PDF
    A developmental network refers to the egocentric network of individuals who take an active interest in and concerted actions toward advancing a protégé’s career. In Part I of this Article, I draw upon the literature to outline the lived experiences of black lawyers, highlighting the need for them to manage their working identity. In Part II, I further develop bicultural experience as a construct for exploring racial minority experience in a professional context with recent developments from the acculturation literature. In Part III, I introduce the developmental network as a vehicle for understanding developmental relationships. Part IV summarizes the methodology for my pilot study and then discusses the preliminary results

    Towards a new ITU-T recommendation for subjective methods evaluating gaming QoE

    Get PDF
    This paper reports on activities in Study Group 12 of the International Telecommunication Union (ITU-T SG12) to define a new Recommendation on subjective evaluation methods for gaming Quality of Experience (QoE). It first resumes the structure and content of the current draft which has been proposed to ITU-T SG12 in September 2014 and then critically discusses potential gaming content and evaluation methods for inclusion into the upcoming Recommendation. The aim is to start a discussion amongst experts on potential evaluation methods and their limitations, before finalizing a Recommendation. Such a recommendation might in the end be applied by non -expert users, hence wrong decisions in the evaluation design could negatively affect gaming QoE throughout the evaluation

    Oral messages improve visual search

    Input multimodality combining speech and hand gestures has motivated numerous usability studies. Contrastingly, issues relating to the design and ergonomic evaluation of multimodal output messages combining speech with visual modalities have not yet been addressed extensively. The experimental study presented here addresses one of these issues. Its aim is to assess the actual efficiency and usability of oral system messages including brief spatial information for helping users to locate objects on crowded displays rapidly. Target presentation mode, scene spatial structure and task difficulty were chosen as independent variables. Two conditions were defined: the visual target presentation mode (VP condition) and the multimodal target presentation mode (MP condition). Each participant carried out two blocks of visual search tasks (120 tasks per block, and one block per condition). Scene target presentation mode, scene structure and task difficulty were found to be significant factors. Multimodal target presentation proved to be more efficient than visual target presentation. In addition, participants expressed very positive judgments on multimodal target presentations which were preferred to visual presentations by a majority of participants. Besides, the contribution of spatial messages to visual search speed and accuracy was influenced by scene spatial structure and task difficulty: (i) messages improved search efficiency to a lesser extent for 2D array layouts than for some other symmetrical layouts, although the use of 2D arrays for displaying pictures is currently prevailing; (ii) message usefulness increased with task difficulty. Most of these results are statistically significant.Comment: 4 page

    Valuing Environmental Factors in Cost-Benefit Analysis Using Data Envelopment Analysis

    Get PDF
    Environmental cost-benefit analysis (ECBA) refers to social evaluation of investment projects and policies that involve significant environmental impacts. Valuation of the environmental impacts in monetary terms forms one of the critical steps in ECBA. We propose a new approach for environmental valuation within ECBA framework that is based on data envelopment analysis (DEA) and does not demand any price estimation for environmental impacts using traditional revealed or stated preference methods. We show that DEA can be modified to the context of CBA by using absolute shadow prices instead of traditionally used relative prices. We also discuss how the approach can be used for sensitive analysis which is an important part of ECBA. We illustrate the application of the DEA approach to ECBA by means of a hypothetical numerical example where a household considers investment to a new sport utility vehicle.Cost-Benefit Analysis, Data Envelopment Analysis, Eco-Efficiency, Environmental Valuation, Environmental Performance, Performance Measurement

    Shopping Context and Consumers' Mental Representation of Complex Shopping Trip Decision Problems

    Get PDF
    Depending on the shopping context, consumers may develop different mental representations of complex shopping trip decision problems to help them interpret the decision situation that they face and evaluate alternative courses of action. To investigate these mental representations and how they vary across contexts, the authors propose a causal network structure that allows for a formal representation of how context-specific benefits requirements affect consumers’ evaluation of decision alternative attributes. They empirically test hypotheses derived from the framework, using data on consumers’ mental representations of a complex shopping trip decision problem across four shopping contexts that differ in terms of opening hour restrictions and shopping purpose, and find support for the proposed structure and hypotheses.retailing;consumer decision-making;context effects;mental representations;shopping trip decisions

    The emergence of a public good through online social capital activation

    Get PDF
    This paper examines how consumers activate online social capital, characterizes the resources which they elicit, and considers of the resulting good’s properties. Content analysis of the initial posts of 975 publicly available threads of an online community reveals six forms of activation, based on whether the activator seeks convergent or divergent responses; and seeks factual information or subjective viewpoints, or mobilizes action. The findings suggest that the network is used in three ways: to (1) source a ‘rare’ resource possessed by at least one member, (2) generate a form of consensus among several members, or (3) combine the divergent resources possessed by different members into a ‘knowledge or action bank’. Hence, the network may be used in a search for ‘unity’ or ‘additively’. An emergent, public good develops in the process. Of particular value for a public good is the unfolding richness that comes from the diversity of resources

    Willingness to Pay to Reduce Mortality Risks: Evidence from a Three-Country Contingent Valuation Study

    Get PDF
    Valuing a change in the risk of death is a key input into the calculation of the benefits of environmental policies that save lives. Typically such risks are monetized using the Value of a Statistical Life (VSL). Because the majority of the lives saved by environmental policies are those of older persons, there has been much recent debate about whether the VSL should be lower for the elderly to reflect their fewer remaining life years. We conducted a contingent valuation survey in the UK, Italy and France designed to answer this question. The survey was administered in these three countries following a standardized protocol. Persons of age 40 and older were asked questions about their willingness to pay for a specified risk reduction. We use their responses to these questions to estimate the willingness to pay (WTP) for such a risk reduction and VSL. Our results suggest that the VSL ranges between €1.052 and €2.258 million. The VSL is not significantly lower for older persons, but is higher for persons who have been admitted to the hospital or emergency room for cardiovascular and respiratory problems. These results suggest that there is no evidence supporting that VSL should be adjusted to reflect the age of the beneficiaries of environmental policy. They are also partly inconsistent with the QALY-based practice of imputing lower values for persons with a compromised health status. We also find that income is positively and significantly associated with WTP. The income elasticities of the WTP increase gradually with income levels and are typically between 0.15 and 0.5 for current income levels in EU countries. We use the responses to the WTP questions to estimate the value of an extension in remaining life expectancy. We find that the value of a month’s extension in life expectancy increases with age and with serious cardiovascular and respiratory illnesses experienced by the respondent. The value of a loss of one year’s life expectancy is between €55,000 and €142,000.Value of a statistical life, Willingness to pay, Life expectancy, Risk reduction, Contingent valuation

    Cultural Neuroeconomics of Intertemporal Choice

    Get PDF
    According to theories of cultural neuroscience, Westerners and Easterners may have distinct styles of cognition (e.g., different allocation of attention). Previous research has shown that Westerners and Easterners tend to utilize analytical and holistic cognitive styles, respectively. On the other hand, little is known regarding the cultural differences in neuroeconomic behavior. For instance, economic decisions may be affected by cultural differences in neurocomputational processing underlying attention; however, this area of neuroeconomics has been largely understudied. In the present paper, we attempt to bridge this gap by considering the links between the theory of cultural neuroscience and neuroeconomic theory\ud of the role of attention in intertemporal choice. We predict that (i) Westerners are more impulsive and inconsistent in intertemporal choice in comparison to Easterners, and (ii) Westerners more steeply discount delayed monetary losses than Easterners. We examine these predictions by utilizing a novel temporal discounting model based on Tsallis' statistics (i.e. a q-exponential model). Our preliminary analysis of temporal discounting of gains and losses by Americans and Japanese confirmed the predictions from the cultural neuroeconomic theory. Future study directions, employing computational modeling via neural networks, are briefly outlined and discussed
