Loyalty in Department Store Online Shopping

The purpose of this paper is to explore knowledge about the influences of e-service quality and technology acceptance model (TAM) on e-satisfaction, loyalty, and online purchase intention in online department store in Bangkok, Thailand. The online model was developed based on e-service quality and TAM. A self-administered questionnaire was employed to collect data from customers who had used and purchased products via online department store outlets. The data were collected from the respondents in Bangkok area during March 2014. 200 completed questionnaires were used to analyze and test the model by applying a Multiple Linear Regression (MLR). The results showed that perceived ease of use (i.e., department store's website is easy to navigate through, payment process is easy to pay, help menu is helpful) has the greatest influence on the e-satisfaction, followed by reliability, and brand image. While customer loyalty has the greatest influence on the online purchase intention, followed by tangible (i.e., the online shopping website looks attractive, the website has good layout).
Differences between leisure-time physical activity, health-related quality of life and life satisfaction: Al Ritmo de las Comunidades, a natural experiment from Colombia

Physical inactivity is one of the major public health problems worldwide. Community-based interventions have been pointed out as a promising strategy to increase physical activity (PA) levels and impact population health. Recreovía is a community program with a potential to promote PA. There is growing evidence for two benefits derived from the practice of PA: an increased perception of health-related quality of life (HRQoL) and life satisfaction (LS). The purpose of this study was to assess differences between leisure-time PA and perceptions of both HRQoL and LS, as well as to assess differences between perceptions of both HRQoL and LS for Recreovía and non-Recreovía participants. Data were obtained using the baseline cross-sectional survey of 1533 participants (501 belonged to the intervention group) as part of the natural experiment Al Ritmo de las Comunidades. HRQoL was measured with the European Organization for Research and Treatment of Cancer 30-item questionnaire, LS was measured with Questions on Life Satisfaction Scale, and self-reported minutes of leisure-time PA were measured with the long version of the International Physical Activity Questionnaire. The mean age of participants was 41.7 years (standard deviation (SD) = 16.3). The participants had a good overall HRQoL and LS. The mean minutes of leisure-time PA were 158.1 min (SD = 230.2) a week. Results showed that those participants who reported higher leisure-time PA levels also reported a significantly higher LS (M = 41.9, SD = 35.0) relative to participants with lower levels (M = 37.6, SD = 34.2, t(1532) = −2.36, p < 0.01). There were no statistical differences in the perception of HRQoL and leisure-time PA (t(1532) = −1.03, p = 0.30), although active people had higher scores. Both HRQoL and LS scores were higher in individuals who were participating in Recreovía (p < 0.001). Higher LS scores were found in the group with higher leisure-time PA, while HRQoL showed no differences. Better psychological well-being indices were found in the Recreovía group.
Learning to collaborate: a study of business networks

Purpose – This paper seeks to give empirical examples of the processes whereby networks learn to collaborate. Specifically, the authors aim to examine efforts to learn to collaborate in response to the challenge of climate change. Design/methodology/approach – The paper uses case study research methods to examine concepts previously developed in the literature and propose a conceptual framework of barriers to learning to collaborate. Findings – Existing research on collaboration over environmental issues highlights the prevalence of cognitive deficiencies, an abundance of conflicts and disputes and the ignorance of exchange opportunities among interdependent actors. Based on a theoretical review and an empirical case study, the authors put forward a framework that involves three stages. The paper proposes that networks learning to collaborate undergo a process of: framing the problem; negotiating; and achieving wise trades. Practical implications – At all three of the stages given above, there are significant cognitive biases, which can lead to failure to learn to collaborate. The paper gives examples that should help businesses and regulators to understand and avoid in-built barriers that could lead to a failure of the network to learn to collaborate. Originality/value – The paper reviews a number of research disciplines linked to collaboration and gives an empirical case study that explores their links. The authors then propose a conceptual framework of barriers to learning to collaborate, which can be used to help guide practitioners. Failure to learn to collaborate can be found in the many contemporary cases of conflicts and disputes; such as in the areas of intellectual property rights, international trade, inter-firm alliances and vertical marketing systems.
Peroxynitrite‐induced oligodendrocyte toxicity is not dependent on poly(ADP‐ribose) polymerase activation

Oligodendrocyte loss is a characteristic feature of several CNS disorders, including multiple sclerosis (MS) and spinal cord injury. However, the mechanisms responsible for oligodendrocyte destruction remain undefined. As recent studies have implicated peroxynitrite in the pathogenesis of both spinal cord injury and MS, we have examined whether peroxynitrite may mediate at least some of the oligodendrocyte damage and demyelination observed in these conditions. Primary rat oligodendrocytes were exposed to authentic peroxynitrite in vitro and assessed for cytotoxicity. Mitochondrial function, measured by the reduction of MTT to formazan, and mitochondrial membrane potential were used as indicators of cell viability. Cell death was quantitated by measuring either the release of lactate dehydrogenase from, or the uptake of propidium iodide into, damaged and dying cells. Peroxynitrite dose‐dependently reduced the viability of primary oligodendrocytes and induced cell death. Furthermore, peroxynitrite significantly increased DNA strand breakage and the activity of poly(ADP‐ribose) polymerase (PARP) in oligodendrocyte cultures. To identify whether PARP activation plays a role in peroxynitrite‐induced oligodendrocyte toxicity, we examined the effects of the PARP inhibitors 3‐aminobenzamide (3AB) and 5‐iodo‐6‐amino‐1,2‐benzopyrone (INH2BP) on mitochondrial function and cell death in oligodendrocytes. The presence of 3AB and INH2BP did not protect oligodendrocytes from peroxynitrite‐induced cytotoxicity. However, both compounds significantly reduced PARP activity in these cells. Primary oligodendrocytes generated from PARP‐deficient mice were also highly susceptible to peroxynitrite‐induced cell death. Therefore, our results show that peroxynitrite exerts cytotoxic effects on oligodendrocytes in vitro independently of PARP activation. GLIA 41:105–116, 2003. © 2003 Wiley‐Liss, Inc.
Spatio-temporal beam dynamics in multimode nonlinear optical fibers

We overview recent advances in the spatio-temporal nonlinear dynamics of optical pulses propagating in multimode optical fibers. The Kerr effect leads to spatial beam self-cleaning in a graded-index multimode optical fiber, followed by sideband series generation spanning multiple octaves. Effectively single mode supercontinuum spanning from the visible to the mid-infrared was also demonstrated. Enhancement of Kerr beam self-cleaning was observed in active fiber with quasi-step index profile. Moreover, mutual self-cleaning was recently reported for both the fundamental and the second harmonic beams in optically poled multimode fibers with cubic and quadratic nonlinearity.
The Continuous Logit Dynamic and Price Dispersion

We define the logit dynamic for games with continuous strategy spaces and establish its fundamental properties , i.e. the existence, uniqueness and continuity of solutions. We apply the dynamic to the analysis of the Burdett and Judd (1983) model of price dispersion. Our objective is to assess the stability of the logit equilibrium corresponding to the unique Nash equilibrium of this model. Although a direct analysis of local stability is difficult due to technical difficulties, an appeal to finite approximation techniques suggest that the logit equilibrium is unstable. Price dispersion, instead of being an equilibrium phenomenon, is a cyclical phenomenon. We also establish a result on the Lyapunov stability of logit equilibria in negative definite games.
Re: Avoiding a post‐nasal pack in adenoidal haemorrhage

Sir, We read with interest, the article written by Dowley & Jones (2008) entitled ‘Avoiding a post-nasal pack in adenoidal haemorrhage’. They described a method of controlling post-nasal bleed using a 45 or 70 degree endoscope trans-orally or 0 degree endoscope transnasally with an insulated flexible suction monopolar diathermy to thoroughly diathermy the adenoid base under direct vision. Lo & Rowe-Jones (2006) have previously published in your journal the technique of trans-oral suction diathermy adenoid ablation under direct vision using a 45 degree endoscope. In this paper, fifty-six patients underwent this procedure with no complications, including haemorrhage. This paper also describes the limitations of trans-oral and trans-nasal 0 degree endoscopes. It is suggestive that instead of using this technique to control adenoidal haemorrhage, it emphasized the benefits to perform adenoidectomy using this technique in the first place not only to prevent haemorrhage but also to allow trainees to demonstrate to the senior surgeon the appropriate anatomy, completed adenoid ablation, and haemostasis.
A Review of Service and E-Service Quality Measurements: Previous Literature and Extension

Abstract: The purpose of this study is to show the requirement of industry-specific national service quality indices for measuring quality in both traditional and electronic services in various industries in a country. In this study, the literature about service and e-service quality measurements was reviewed, and a three-dimensional framework was developed. It was found out that the dimensions of each service quality measurement were all different from each other due to the different characteristics of the industries that each study has been conducted in. The study showed that there is a need for an industry-specific national service quality index and suggested that national customer satisfaction indices which have existed in the literature can be a model for industry-specific national service quality indices. An industry-specific national service quality index enables national companies to understand their unique industrial characteristics that needed to be improved continuously in order to increase service quality and gain competitive advantage. The index which was proposed to develop in the future was suggested for the first time in this study. Keywords: Service quality; E-service quality; Service quality dimensions; National customer satisfaction indices; Turkish Customer Satisfaction Index (TCSI).
Opioid analgesics in palliative care

The discovery of the opioid receptors began in the 1970s and three (μ, δ and κ) are now recognised. Most current opioid analgesics interact preferentially with μ receptors, although some have actions at δ and κ receptors. The revelation that opioid receptors are present on peripheral sensory neurons and immune system cells,1,2 has led to the realisation that the opioid system is involved in a host of actions, including the central and peripheral modulation of pain transmission and the regulation of immune and neuroendocrine processes.

The Use and Value of Social Information in Selective Selling of Exclusive Products

We consider the use and value of social-network information in selectively selling goods and services whose value derives from exclusive ownership among network connections or friends. Our model accommodates customers who are heterogeneous in their number of friends (degree) and their proclivity for social comparisons (conspicuity). Firms with information on either (or both) of these characteristics can use it to make the product selectively available and to personalize prices. We find that firms’ preferred customers are low degree and high conspicuity, with the conspicuity threshold nondecreasing in degree. Interestingly, although both degree and conspicuity levels are relevant to curating the desired customer base, we find that firms do not need conspicuity information to do so; its absence can be substituted by incentivizing customers to self-select. There is no such recourse for the absence of degree information. As a result, degree information is typically more valuable than conspicuity information. Our analysis suggests that there are two canonical categories of social information—less valuable “consonant” information on characteristics where firm and customer preferences are aligned and more valuable “competing” information where preferences are misaligned. Customers can be incentivized to act in a way that their actions are a perfect substitute for consonant information, making it less valuable.

Lessons learned towards a best practices model of virtual reality intervention for individuals with intellectual and developmental disability

Individuals with intellectual and developmental disabilities (IDD) are in need of effective physical fitness training programs, leisure time opportunities and strategies to improve their participation. The overall objective was to gather “lessons learned” towards the formulation of a best practices model for the application of VR intervention for adults with IDD. During study 1 a group of 33 participants (mean age = 28.1 ± 5.3 years; moderate IDD level) underwent a 12 week program of 2–3 30 minute sessions per week consisting of game-like exercises provided by the GestureTek's IREX VR operated by an occupational therapist. During study 2 a research group (N=30; mean age = 52.3 ± 5.8 years; moderate IDD level) participated in a 6 week fitness program of three 30 minute sessions per week consisting of game-like exercises provided by the Sony PlayStation II EyeToy VR system. Changes in physical fitness were monitored by the Energy Expenditure Index (EEI), the modified 12 min walk\run and the Total Heart Beat Index (THBI). Results were compared to a control group (N=30, mean age = 54.3 ± 5.4 years). During study 3, 24 participants with severe levels of IDD (N=30; mean age = 52.3 ± 5.8 years; moderate IDD level) were matched for age, IDD level and functional abilities with a control group (N=30, mean age = 54.3 ± 5.4 years). The research group participated in an 8 week VR program (3 times per week) using GestureTek's IREX video capture technology operated by the local caregiver staff. The VR programs were found to attract full participation by the participants at moderate levels of IDD but some difficulties were found in fully engaging all individuals at severe levels of IDD. Different commercial VR systems were used and were found to be usable by health-profession students and local caregiver staff. Significant (P≪0.05) improvements in physical fitness were demonstrated for the research group in comparison to the control group. VR technology is an effective tool to engage individuals with IDD in a variety of activities by operators of different educational background and professions. VR technology could be successfully operated for adults at mild, moderate and severe levels of IDD and VR technology resulted in significant improvements in the physical fitness levels of the participants. Further research is needed to complete the construction of a “best practice” model.
Coproduction of Transformative Services as a Pathway to Improved Consumer Well-Being

Although many consumers turn to financial counseling to improve their financial well-being, the effectiveness of these counseling services remains nebulous and the exact mechanisms through which they improve consumer well-being require further research. This longitudinal research demonstrates that consumers’ coproduction of financial counseling services is pivotal for increasing their credit scores and for decreasing their financial stress. Drawing on self-determination theory, this study also shows that financial literacy, consumer involvement, and attachment styles are important drivers of coproduction. Involvement plays a moderating role, such that higher involvement substitutes for lower levels of financial literacy and mitigates the negative effects of attachment avoidance on coproduction. These findings help both counseling agencies and public policy makers improve the effectiveness of financial counseling. Financial counselors should track their customers’ objective and subjective financial literacy, involvement, and attachment styles, then segment customers, and, finally, tailor the service provision accordingly, to leverage coproduction as the pathway to consumers’ financial well-being. From a public policy perspective, the findings suggest that efforts to improve consumer financial literacy are important but should be supplemented with programs designed to increase consumer involvement in financial counseling; this combination promises to foster coproduction and improve consumers’ financial well-being.
A nomogram for predicting the optimal oral dosage of tacrolimus in liver transplant recipients with small‐for‐size grafts

Abstract: No optimal tacrolimus dosage regimen suitable for clinical use in liver transplant recipients has yet been established. The purpose of this study was to determine the factors affecting the optimal dosage and pharmacokinetics of tacrolimus in living donor liver transplantation, and a nomogram for optimal tacrolimus dosage in the immediate postoperative period for recipients with small‐for‐size grafts was constructed. Twenty‐four liver transplant patients (nine males and 15 females) and 24 donors (10 males and 14 females) were enrolled in this study. Two studies were performed. In study 1, the effect of the actual ratio of graft volume to standard liver volume (GV/SV ratio) on the elimination half‐life (T1/2) of tacrolimus in the immediate postoperative period was analysed, and a nomogram for estimating the optimal oral dose of tacrolimus required to reach a target concentration was established. In study 2, the effect of donor age on the recovery of hepatic function with ability of the graft to eliminate tacrolimus was analysed. In the immediate postoperative period, T1/2 of tacrolimus showed great variability between patients, with values ranging from 16.3 to 110.9 h. Graft size (GV/SV ratio) is important and could influence intraindividual variations in the optimal dosage and T1/2 of tacrolimus. The recovered T1/2 ratio (T1/2 ratio=T1/2 1–10 d/T1/2 30–40 d), this ratio being related to the recovery of hepatic function with ability of the graft to eliminate tacrolimus, showed great variability between patients, with values ranging from 1.08 to 4.21 (mean±SD, 1.95±0.81). Age of the donor is a major factor affecting the recovered ratio of the graft to metabolize tacrolimus. The nomogram that we have constructed, based on graft size (GV/SV ratio), will easily provide optimal dose for each patient with small‐for‐size graft in the early postoperative period.
Exploring the Dimensions of Consumer Privacy: An Analysis of Coverage in British and American Media

This study examines how consumer privacy issues have been perceived over time and across cultures through the analysis of media coverage of the issue in England and the United States over the past 33 years. A major cross-cultural difference was that Americans have expressed more concern about interactional privacy issues (such as intrusions into individuals’ lives through the receipt of direct mail and telephone solicitations). While the British have been primarily concerned with informational privacy issues (such as the collection and exchange of information about individuals). Other differences in coverage over time and across cultures are also presented, and implications for direct marketers are discussed.
On measuring the contribution from firm turnover to aggregate productivity growth. Selection on profitability and not productivity

Foster et al. (2001) outline a framework that is commonly used to identify the contribution from firm turnover to aggregate productivity growth. The framework is not derived from economic theory and it implies that productivity levels determine the contribution from reallocation and firm turnover. In this paper, I outline an index for aggregate productivity growth based on economic theory. In contrast to common beliefs, I show that the contribution from firm turnover to aggregate productivity growth should be based on the profitability, and not the productivity, of these firms.
Complications of cesarean deliveries among HIV-infected women in the United States

Objective:To compare rates of complications associated with cesarean delivery in HIV-infected and HIV-uninfected women in the United States and to investigate trends in such complications across four study cycles spanning the implementation of HAART in the United States (1995–1996, 2000–2001, 2005–2006, 2010–2011). Design:The Nationwide Inpatient Sample from the Healthcare Cost and Utilization Project is the largest all-payer hospital inpatient care database in the United States; when weighted to account for the complex sampling design, nationally representative estimates are derived. After restricting the study sample to women aged 15–49 years, our study sample consisted of approximately 1 090 000 cesarean delivery hospitalizations annually. Methods:Complications associated with cesarean deliveries were categorized as infection, hemorrhage, or surgical trauma, based on groups of specific International Classification of Diseases 9th revision codes. Length of hospitalization, hospital charges, and in-hospital deaths were also examined. Results:The rate of complications significantly decreased during the study periods for HIV-infected and HIV-uninfected women. However, rates of infectious complications and surgical trauma associated with cesarean deliveries remained higher among HIV-infected, compared with HIV-uninfected women in 2010–2011, as did prolonged hospital stay and in-hospital deaths. Length of hospitalization decreased over time for cesarean deliveries of HIV-infected women to a greater extent compared with HIV-uninfected women. Conclusion:In the United States, rates of cesarean delivery complications decreased from 1995 to 2011. However, rates of infection, surgical trauma, hospital deaths, and prolonged hospitalization are still higher among HIV-infected women. Clinicians should remain alert to this persistently increased risk of cesarean delivery complications among HIV-infected women.
