    Imaginary relish and exquisite torture: The elaborated intrusion theory of desire

    Get PDF
    The authors argue that human desire involves conscious cognition that has strong affective connotation and is potentially involved in the determination of appetitive behavior rather than being epiphenomenal to it. Intrusive thoughts about appetitive targets are triggered automatically by external or physiological cues and by cognitive associates. When intrusions elicit significant pleasure or relief, cognitive elaboration usually ensues. Elaboration competes with concurrent cognitive tasks through retrieval of target-related information and its retention in working memory. Sensory images are especially important products of intrusion and elaboration because they simulate the sensory and emotional qualities of target acquisition. Desire images are momentarily rewarding but amplify awareness of somatic and emotional deficits. Effects of desires on behavior are moderated by competing incentives, target availability, and skills. The theory provides a coherent account of existing data and suggests new directions for research and treatment

    Welfare Polls: A Synthesis

    Get PDF
    Welfare polls are survey instruments that seek to quantify the determinants of human well-being. Currently, three welfare polling formats are dominant: contingent valuation (CV) surveys, quality-adjusted life year (QALY) surveys, and happiness surveys. Each format has generated a large, specialized, scholarly literature, but no comprehensive discussion of welfare polling as a general enterprise exists.This Article seeks to fill that gap. Part I describes the trio of existing formats. Part II discusses the current and potential uses of welfare polls in governmental decisionmaking. Part III analyzes in detail the obstacles that welfare polls must overcome to provide useful well-being information, and concludes that they can be genuinely informative. Part IV synthesizes the case for welfare polls, arguing against two types of challenges: the revealed-preference tradition in economics, which insists on using behavior rather than surveys to learn about well-being; and the civic republican tradition in political theory, which accepts surveys but insists that respondents should be asked to take a citizen rather than consumer perspective. Part V suggests new directions for welfare polls

    Welfare Polls: A Synthesis

    "Welfare polls" are survey instruments that seek to quantify the determinants of human well-being. Currently, three "welfare polling" formats are dominant: contingent-valuation surveys, QALY surveys, and happiness surveys. Each format has generated a large, specialized, scholarly literature, but no comprehensive discussion of welfare polling as a general enterprise exists. This Article seeks to fill that gap. Part I describes the trio of existing formats. Part II discusses the actual and potential uses of welfare polls in government decision making. Part III analyzes in detail the obstacles that welfare polls must overcome to provide useful well-being information, and concludes that they can be genuinely informative. Part IV synthesizes the case for welfare polls, arguing against two types of challenges: the revealed-preference tradition in economics, which insists on using behavior rather than surveys to learn about well-being; and the civic-republican tradition in political theory, which accepts surveys but insists that respondents should be asked to take a "citizen", rather than "consumer" perspective. Part V suggests new directions for welfare polls.

    Spatiotemporal Patterns of Urban Human Mobility

    Get PDF
    The modeling of human mobility is adopting new directions due to the increasing availability of big data sources from human activity. These sources enclose digital information about daily visited locations of a large number of individuals. Examples of these data include: mobile phone calls, credit card transactions, bank notes dispersal, check-ins in internet applications, among several others. In this study, we consider the data obtained from smart subway fare card transactions to characterize and model urban mobility patterns. We present a simple mobility model for predicting peoples’ visited locations using the popularity of places in the city as an interaction parameter between different individuals. This ingredient is sufficient to reproduce several characteristics of the observed travel behavior such as: the number of trips between different locations in the city, the exploration of new places and the frequency of individual visits of a particular location. Moreover, we indicate the limitations of the proposed model and discuss open questions in the current state of the art statistical models of human mobility

    A Novel approach to a wearable eye tracker using region-based gaze estimation

    Get PDF
    Eye tracking studies are useful to understand human behavior and reactions to visual stimuli. To conduct experiments in natural environments it is common to use mobile or wearable eye trackers. To ensure these systems do not interfere with the natural behavior of the subject during the experiment, they should be comfortable and be able to collect information about the subject\u27s point of gaze for long periods of time. Most existing mobile eye trackers are costly and complex. Furthermore they partially obstruct the visual field of the subject by placing the eye camera directly in front of the eye. These systems are not suitable for natural outdoor environments due to external ambient light interfering with the infrared illumination used to facilitate gaze estimation. To address these limitations a new eye tracking system was developed and analyzed. The new system was designed to be light and unobtrusive. It has two high definition cameras mounted onto headgear worn by the subject and two mirrors placed outside the visual field of the subject to capture eye images. Based on the angular perspective of the eye, a novel gaze estimation algorithm was designed and optimized to estimate the gaze of the subject in one of nine possible directions. Several methods were developed to compromise between shape-based models and appearance-based models. The eye model and features were chosen based on the correlation with the different gaze directions. The performance of this eye tracking system was then experimentally evaluated based on the accuracy of gaze estimation and the weight of the system

    Museums and Digital Culture: New perspectives and research

    Get PDF
    This richly illustrated book offers new perspectives and research on how digital culture is transforming museums in the 21st century, as they strive to keep pace with emerging technologies driving cultural and social change, played out not only in today’s pervasive networked environment of the Internet and Web, but in everyday life, from home to work and on city streets. In a world where digital culture has redefined human information behavior as life in code and digits, increasingly it dominates human activity and communication. These developments have radically changed the expectations of the museum visitor, real and virtual, the work of museum professionals and, most prominently, the nature of museum exhibitions, while digital art and life in a digitally saturated world is changing our ways of seeing, doing, our senses and aesthetics. Overall, this book creates a new picture of the 21st-century museum field. As museums become shared spaces with their communities, local, national and global and move from collection-centered to user-/visitor-centered institutions, they are assuming new roles and responsibilities tied to new goals for engaging their audience, conveying meaning through collections, creating learning experiences and importantly, connecting to daily digital life and culture integral to the museum ecosystem. Our studies of recent exhibitions at museums leading change are used to exemplify new directions, while they point to a reimagined vision for museums of the future at the heart of which is the integration of digital culture and visitor experience and participation in real and virtual space

    Factors That Enhance Consumer Trust in Human-Computer Interaction: An Examination of Interface Factors and Moderating Influences

    Get PDF
    The Internet coupled with agent technology presents a unique setting to examine consumer trust. Since the Internet is a relatively new, technically complex environment where human-computer interaction (HCI) is the basic communication modality, there is greater perception of risk facing consumers and hence a greater need for trust. In this dissertation, the notion of consumer trust was revisited and conceptually redefined adopting an integrative perspective. A critical test of trust theory revealed its cognitive (i.e., competence, information credibility), affective (i.e., benevolence), and intentional (i.e., trusting intention) constructs. The theoretical relationships among these trust constructs were confirmed through confirmatory factor analysis and structural equation modeling. The primary purpose of this dissertation was to investigate antecedent and moderating factors affecting consumer trust in HCI. This dissertation focused on interface-based antecedents of trust in the agent-assisted shopping context aiming at discovering potential interface strategies as a means to enhance consumer trust in the computer agent. The effects of certain interface design factors including face human-likeliness, script social presence, information richness, and price increase associated with upgrade recommendation by the computer agent were examined for their usefulness in enhancing the affective and cognitive bases for consumer trust. In addition, the role of individual difference factors and situational factors in moderating the relationship between specific types of computer interfaces and consumer trust perceptions was examined. Two experiments were conducted employing a computer agent, Agent John, which was created using MacroMedia Authorware. The results of the two experiments showed that certain interface factors including face and script could affect the affective trust perception. Information richness did not enhance consumers’ cognitive trust perceptions; instead, the percentage of price increase associated with Agent John’s upgrade recommendation affected individuals’ cognitive trust perceptions. Interestingly, the moderating influence of consumer personality (especially feminine orientation) on trust perceptions was significant. The consequences of enhanced consumer trust included increased conversion behavior, satisfaction and retention, and to a lesser extent, self-disclosure behavior. Finally, theoretical and managerial implications as well as future research directions were discussed

    New Directions in Compensation Research: Synergies, Risk, and Survival

    Get PDF
    We describe and use two theoretical frameworks, the resource-based view of the firm and institutional theory, as lenses for examining three promising areas of compensation research. First, we examine the nature of the relationship between pay and effectiveness. Does pay typically have a main effect or, instead, does the relationship depend on other human resource activities and organization characteristics? If the latter is true, then there are synergies between pay and these other factors and thus, conclusions drawn from main effects models may be misleading. Second, we discuss a relatively neglected issue in pay research, the concept of risk as it applies to investments in pay programs. Although firms and researchers tend to focus on expected returns from compensation interventions, analysis of the risk, or variability, associated with these returns may be essential for effective decision-making. Finally ,pay program survival, which has been virtually ignored in systematic pay research, is investigated. Survival appears to have important consequences for estimating pay plan risk and returns, and is also integral to the discussion of pay synergies. Based upon our two theoretical frameworks, we suggest specific research directions for pay program synergies, risk, and survival

    Reflecting on E-Recruiting Research Using Grounded Theory

    Get PDF
    This paper presents a systematic review of the e-Recruiting literature through a grounded theory lens. The large number of publications and the increasing diversity of publications on e-Recruiting research, as the most studied area within e-HRM (Electronic Human Resource Management), calls for a synthesis of e-Recruiting research. We show interconnections between achievements, research gaps and future research directions in order to advance both e-Recruiting research and practice. Moreover, we provide a definition of e-Recruiting. The use of grounded theory enabled us to reach across sub-disciplines, methods used, perspectives studied, themes discussed and stakeholders involved. We demonstrate that the Grounded Theory Approach led to a better understanding of the interconnections that lay buried in the disparate e-Recruiting literature
