    Psychological reasons for consumer trust in e-retailing

    Get PDF
    This research in progress expands on existing research on e-retailing by examining the psychological factors that influence consumer trust in e-retailing. The psychological factors expected to influence trust are personality-based factors, perception-based factors, experience-based factors, knowledge-based factors and attitude. Hypotheses have been developed based on a thorough review of the trust literature. A pilot study has been conducted in the Netherlands and the results hereof are included in this paper.management information;

    Who Has Control in the Courtroom?: Maine Lawyers\u27 Process for Client Representation Family Matters Cases and How Perceptions of Coercive Control Impact Their Process

    Supervising Professor: Rachel Casey Informed by the researcher’s work with women struggling through separation and child custody legal proceedings with their abusive male co-parents, the study seeks to understand if and how Maine’s court system considers intimate partner violence (IPV) in family matters cases. The research aims to gain specific insight into family lawyers’ understanding and consideration of coercive control—a term encompassing gender-based, psychologically abusive and controlling behaviors—when representing clients in divorce and parental rights and responsibilities cases. Under the label “post-separation abuse,” growing literature demonstrates the extent to which coercive control among separating co-parents manifests through the family court process. Research shows the many ways in which family courts have entirely discounted and/or misunderstood the experiences of IPV victimized parents when making child custody determinations, a process that is often complex and re-traumatizing for victim-survivors. To add, Maine funnels family matters cases through its underresourced district court system. To break down silos between systems supporting separating families and allow for more coordinated response to aid those experiencing abuse, it is crucial to identify gaps in Maine’s legal system that impact IPV-victimized parents in family matters cases. The present study aims to broaden understanding of the legal perspective on coercive control in the context of family matters to help bridge gaps between involved professions and inform policy change in Maine. 3 The study uses grounded theory methodology that aims to discover or construct theory from qualitative data using comparative analysis. The researcher collected data via interviewing 10 Maine attorneys with family law experience. Findings rendered a fairly linear process by which lawyers evaluate cases and make strategic decisions for representing clients; mutually reinforcing beliefs, experiences, and knowledge inform this process. Commonly identified challenges included striking a balance between validating clients’ abuse experiences with maintaining realistic desired case outcomes, Protection from Abuse (PFA) orders potentially complicating family matters and escalating abuse, and the adversarial nature of court proceedings. Study findings point to Maine family lawyers’ frustrations with the state legal system and their awareness of challenges that IPV victims face during the family matters process with their abusive co-parents. While the study has its limitations in terms of a small sample size and participant bias, potentially meaningful implications for legal and social work practice, policy, and research are discussed, such as: examining current state law for opportunities to expand the abuse definition to include coercive control similar to what the State of California has done (California Domestic Violence Prevention Act, 2020); implementing more systems coordination and cross-sector professional training on IPV/coercive control; further exploring alternative, non-adversarial, and trauma-informed models of family matters case resolution

    Role of Sediment Resuspension on Estuarine Suspended Particulate Mercury Dynamics

    Coastal sediments are an important site for transient and long-term mercury (Hg) storage, and they foster a geochemical environment optimal for Hg methylation. Therefore, efforts have been taken to constrain the role of sediments as a source of methylmercury (MeHg) to the estuarine water column. This study employed the Gust Microcosm Erosion Core system capable of quantifying particle removal from undisturbed cores under measurable shear stress conditions to assess particulate Hg and MeHg exchange between sediments and the water column. Samples were collected from organic-rich and organic-poor sediment types from the mid- and lower Delaware Bay. It was found that bulk sediment samples from organic-rich systems overpredict total Hg and MeHg release to the water column, whereas organic-poor sediments underpredict the exchange. In general, organic-rich sediments in shallow environments have the most impact on surface particle dynamics. There is little evidence to suggest that MeHg formed in the sediments is released to the water column via particulate exchange, and therefore, nonsedimentary sources likely control MeHg levels in this estuarine water column

    Extending Linear System Models to Characterize the Performance Bounds of a Fixating Active Vision System

    If active vision systems are to be used reliably in practical applications, it is crucial to understand their limits and failure modes. In the work presented here, we derive, theoretically and experimentally, bounds on the performance of an active vision system in a fixation task. In particular, we characterize the tracking limits that are imposed by the finite field of view. Two classes of target motion are examined: sinusoidal motions, representative for targets moving with high turning rates, and constant-velocity motions, exemplary for slowly varying target movements. For each class of motion, we identify a linear model of the fixating system from measurements on a real active vision system and analyze the range of target motions that can be handled with a given field of view. To illustrate the utility of such performance bounds, we sketch how the tracking performance can be maximized by dynamically adapting optical parameters of the system to the characteristics of the target motion. The originality of our work arises from combining the theoretical analysis of a complete active vision system with rigorous performance measurements on the real system. We generate repeatable and controllable target motions with the help of two robot manipulators and measure the real-time performance of the system. The experimental results are used to verify or identify a linear model of the active vision system. A major difference to related work lies in analyzing the limits of the linear models that we develop. Active vision systems have been modeled as linear systems many times before, but the performance limits at which the models break down and the system loses its target have not attracted much attention so far. With our work we hope to demonstrate how the knowledge of such limits can be used to actually extend the performance of an active vision system
