Exploring Online Double Deviation Effect from Psychological Contract Violation, Emotion, and Power Perspectives

Service recovery is a critical moment of truth in retaining customers and reinforcing customer relationships, and has been considered as an “Achilles\u27 heel” in online marketplaces. Poor service recoveries exacerbate the negative effects of the failure, producing a “double deviation” effect. The double deviation effect may arise from the seller’s power misuse and then dissolve the buyer-seller relationship (e.g., violate consumer psychological contract), elicit consumer negative emotions which lead to customer coping behaviors. This study links the theories of psychological contract violation (PCV), emotion, and coping from the power perspective to investigate the double deviation scenario in online auction marketplaces. Two moderators (perceived power and perceived consumer empowerment) are considered in our proposed model. Data collected from 190 consumers of one auction website provide support for the proposed model. The results shed light on what constitutes the determinants of consumer judgments while facing double deviation scenario and how consumers react to and cope with it in online marketplaces. Finally, implications and limitations are discussed in the last part of this paper. Available at: https://aisel.aisnet.org/pajais/vol6/iss1/4

One plus one more than two : university-community partnerships for elderly : an interdisciplinary service-learning project

Faculties at Taipei Medical University developed an interdisciplinary courses cluster which consists of Chinese History, Nutrition, Elderly Activity Design, and Physical Examination. In this course cluster, faculties, students, teaching assistant, and NPO/community members serve the same elderly over two years by providing health related care in accordance with the courses objectives. In this project, not only students\u27 soft abilities, such as problem-solving skills, team work abilities, and communication abilities, are improved, but also develop some pilot devices for the elderly, such as remote health examination and instant soft meal. The paper will describe this model of interdisciplinary service-learning in health professions education, explores common experiences and themes across courses, and identifies key components for success

ANTECEDENTS OF CITIZENSHIP BEHAVIORS IN OPEN PROFESSIONAL VIRTUAL COMMUNITIES

As with organizational development, citizenship behavior should be central to the development and success of open professional virtual communities (OPVC). An increasing literature emphasizes on predicting knowledge contribution behaviors in virtual communities from the extrinsic and intrinsic motivation or benefit perspectives. In line with the consumer behavior literature that distinguishes between hedonic and utilitarian shopping values, we classify these motivations or benefits of knowledge sharing into either hedonic or utilitarian. We propose and test a theoretical model in which hedonic value and utilitarian value are operationalized as formative second-order constructs and examine their effects on members’ satisfaction with sharing knowledge and citizenship behaviors in an open professional virtual community. Data collected from 428 members of one OPVC provide support for the proposed model. The results help understanding how utilitarian value and hedonic value differ in their relationships with satisfaction and VCCB of knowledge contributors. Implications for theory and practice and limitations are discussed

Exploring Consumers’ Coping Behaviors in Online Double Deviation Scenarios: From Power Perspective

Service recovery is a critical moment of truth in retaining customers and reinforcing customer relationships, and has been considered as an “Achilles\u27 heel” in online marketplaces. Poor service recoveries exacerbate the negative effects of the failure, producing a “double deviation” effect. The double deviation effect may arise from the seller’s power misuse and then dissolve the buyer-seller relationship (e.g., violate consumer psychological contract), elicit consumer negative emotions which lead to customer coping behaviors. This study links the theories of psychological contract violation (PCV), emotion, and coping from the power perspective to investigate the double deviation scenario in online auction marketplaces. Two moderators (perceived power and perceived consumer empowerment) are considered in our proposed model. Data collected from 181 consumers of one auction website provide support for the proposed model. The results shed light on what constitutes the determinants of consumer judgments while facing double deviation scenario and how consumers react to and cope with it in online marketplaces.

Assessment of gene-covariate interactions by incorporating covariates into association mapping

The HLA region is considered to be the main genetic risk factor for rheumatoid arthritis. Previous research demonstrated that HLA-DRB1 alleles encoding the shared epitope are specific for disease that is characterized by antibodies to cyclic citrullinated peptides (anti-CCP). In the present study, we incorporated the shared epitope and either anti-CCP antibodies or rheumatoid factor into linkage disequilibrium mapping, to assess the association between the shared epitope or antibodies with the disease gene identified. Incorporating the covariates into the association mapping provides a mechanism 1) to evaluate gene-gene and gene-environment interactions and 2) to dissect the pathways underlying disease induction/progress in quantitative antibodies

Duration of untreated bipolar disorder: A multicenter study

Little is known about the demographic and clinical differences between short and long duration of untreated bipolar disorder (DUB) in Chinese patients. This study examined the demographic and clinical features of short (≤2 years) and long DUB (\u3e2 years) in China. A consecutively recruited sample of 555 patients with bipolar disorder (BD) was examined in 7 psychiatric hospitals and general hospital psychiatric units across China. Patients’ demographic and clinical characteristics were collected using a standardized protocol and data collection procedure. The mean DUB was 3.2 ± 6.0 years; long DUB accounted for 31.0% of the sample. Multivariate analyses revealed that longer duration of illness, diagnosis of BD type II, and earlier misdiagnosis of BD for major depressive disorder or schizophrenia were independently associated with long DUB. The mean DUB in Chinese BD patients was shorter than the reported figures from Western countries. The long-term impact of DUB on the outcome of BD is warranted

The role of autologous bone graft in surgical treatment of hypertrophic nonunion of midshaft clavicle fractures

AbstractBackgroundThis study was conducted to evaluate the results of treating hypertrophic nonunion of mid-shaft clavicle fracture with a limited contact dynamic compression plate (LC-DCP) without autologous cancellous bone graft.MethodsFrom 1995 to 2008, 51 cases of hypertrophic nonunion of mid-shaft clavicle fracture were managed with open reduction and internal fixation by LC-DCP without bone graft involvement. Of these 51 cases, 30 had nonunion after failure of initial surgical treatment (Group 1), and 21 had nonunion after failure of conservative treatment (Group 2). Preoperative and postoperative case management were the same for both groups, with the average follow-up period being 20.4 months (range 18–36). Our study evaluated the radiographic results and functional outcomes of these cases according to the quick disability of arm, shoulder, and hand score.ResultsAll 51 cases resulted in uneventful unions. There was no statistically significant difference between the two groups regarding patient demography, cause of injury, preoperative and postoperative functional scores, length of operation, union time, and duration of hospitalization (p>0.05).ConclusionLC-DCP fixation is an effective method for treating hypertrophic nonunion of mid-shaft clavicle fracture. Local bone graft is sufficient to achieve necessary union, and autologous bone graft from other sites of the body appears unnecessary
