Customer competency for improving firm decision-making performance in e-commerce
Authors: Gupta Vivek , Gupta Laxmi , Dhir Sanjay 
Published: February 2020

PurposeThe purpose of this paper is to analyze customers’ purchasing behavior with respect to perceived benefit and the perceived risk towards customer competency in firms. In this research, the authors validate the concept of customer competency in eight dimensions (i.e. e-trust, quality of products and services, customer support, application design, reasonable price, availability of user-generated content, replacement and returns and risk in purchasing products) and examine empirically its impression on company’s decision-making performance.Design/methodology/approachThe findings are based on an empirical analysis of survey data from 69 respondents and demonstrate a large, significant and positive relationship between customer competency and firm’s decision-making performance.FindingsThe results reveal that majorly three dimensions of competency, i.e. application design, reasonable price and user-generated content (UGC), will impact significantly the decision making performance of firm. This is the empirical study to conceptualize, operationalize and validate the concept of customer competency and to study its impact on decision-making performance. The validity of customer competency constructs as conceived and operationalized suggests the potential future scope by evaluating its relationship with possible antecedents and consequences. For practitioners, the result provides important guidelines for increasing firm’s decision-making performance through the use of customer behavior.Research limitations/implicationsFurther in this research, it is critical to understand that other constructs of customer competency may likewise play an important part in the advancement of expectations of customers. These constructs comprise customers’ self-effectiveness, encouragement and innovation thinking (i.e. observed comparative advantage, complexity and compatibility) of business-to-customer firms in e-commerce. Future research studying these constructs could improve the understanding of success factors for e-commerce firms. The model used in this study can further be extended to understand the variance in a firm’s decision-making.Originality/valueThe prime target of this questionnaire was to gather all of the information about how consumers behave while interacting with e-commerce portals. The questions were based on the factors identified in literature reviews. Previous studies also look at consumer competency toward a particular internet portal and its vendors; however, through this survey, the authors want to look at how consumers behave while shopping on e-commerce portals. This was a clear representation of the authors’ research strategy.

Published: February 2020

PurposeThe purpose of this paper is to synthesize a dyadic theoretical model which takes social-oriented and individual-initiative drivers into account and illustrates a mechanism between social commerce intention and its antecedents in the hospitality industry. To understand tourist social commerce behaviors, the current study puts forward a comprehensive model and investigates the impact among social support, social capital, participant involvement and social identification on tourist propensity to engage in social commerce with behaviors such as to like, share, post reviews and make purchases.Design/methodology/approachThe current research draws on social exchange theory and social penetration theory to study how social-oriented drivers (i.e., social support and social capital) and individual-initiated drivers (i.e., participant involvement and social identification) could better explain tourists’ social commerce intentions. Structural equation modeling was performed based on a sample of 569 hotel guests from 61 hotels in Macau.FindingsResults reveal that social capital mediates the relationship between social support and social commerce behavioral intention. This chain of relationship is moderated by social identification in that the more a hotel guest identifies himself/herself as an in-group member of an online community, the more likely he/she would engage in social commerce behaviors.Practical implicationsThe diffusion velocity of marketing effect is manifested through customers’ social commerce intentions and behaviors, which helps managers to identify the importance in maintaining a supportive atmosphere to nurture intimate member-to-member and member-to-provider relationships.Originality/valueThe present study enriches the social penetration theory and social exchange theory by showing how both individual and social perspectives could jointly influence hotel guest propensity to post likes and comments and to reserve hotel rooms, as means to build more intimate relationships with the members within a virtual community.
Reaching sustainability during a digital transformation: a PLS approach
Authors: El Hilali Wail , El Manouar Abdellah , Janati Idrissi Mohammed Abdou 
Published: February 2020

Purpose
In a world where big data have become crucial to guarantee the success of companies, digital transformation came to help companies transition towards a digital business and accept the changes in the organizational structure as well as the market. Nonetheless, even with the ever-growing importance shed on it, few articles and studies have linked it to the sustainability paradigm. Empirical studies that have linked between the factors of digital transformation and a more sustainable business are still scant. Many efforts are still needed to reduce the knowledge gap between these two concepts. The purpose of this paper is to fill this gap by examining (empirically) the effect of digital transformation on sustainability.

Design/methodology/approach
The study validates five different hypotheses highlighted by the literature using structural equation model (SEM) analysis from partial least square (PLS) approach. It uses a new conceptual framework using a survey data, answered by 41 small- and medium-sized enterprises (SMEs) in Morocco from different industries.

Findings
Using PLS-SEM modeling, the results show that customers, data and innovation, which are drivers that companies should work on during a digital transformation, have a significant impact on companies’ quest to reach sustainability. However, and in contrast to the existing literature, authors find that competition did not play a significant role in enhancing the companies’ commitment to sustainability.

Practical implications
Authors’ findings encourage firms to seize the opportunity of digital transformation to embrace sustainability, because the implementation of these two concepts requires radical changes at the business model level. Authors suggest that the road to achieve sustainability in a digital era should focus on three main axes, enhancing the customer experience and adopting customer centricity, building data analytics capabilities and shifting innovation to the business model level.

Originality/value
To the best of the authors’ knowledge, this study is one of the first research papers that explain how to reach sustainability during a digital transformation. The originality of this paper lies in the fact that it focuses on SMEs as they remain the backbone of the Moroccan economy. This study is also novel for showing with empirical evidences that working on the axes of customers, data and innovation, during a digital transformation journey, will improve sustainable practices within businesses.
Audit certification, earnings management and risk governance: a moderated-mediation analysis
Authors: Fakhfakh Imen , Jarboui Anis 
Published: February 2020

PurposeThe purpose of this study is to document the mediating effect of earnings management on the relation between the components of audit certification. The study is performed under different levels of corporate governance effectiveness in the Tunisian context. The main objective is to empirically examine the ability of discretionary accruals to mediate the relationship between the audit reporting quality and audit risk and to define how the levels of risk governance moderate this relation.Design/methodology/approachStructural equation modeling (SEM) approach is applied for a panel data set of 28 Tunisian companies listed in the Tunis Stock Exchange (TSE) between 2006 and 2013. Furthermore, a moderated-mediation model is developed to examine the mediating role of earnings management. This model is considered to emphasize the moderating role of corporate governance on the relationship between audit-reporting quality and audit risk.FindingsThe results of this study show that earnings management mediates the moderating role of corporate governance on the relationship between timely disclosure and audit risk. Thus, this investigation empirically demonstrates that risk governance moderates both the relationship between the timely disclosure and earnings management, and the relationship between earnings management and audit risk, i.e., the mediating role of earnings management varies depending on the level of risk governance.Practical implicationsInvestors and other external users of financial statements need to care about the audit risk by the audit-reporting quality (audit accuracy and timely disclosure). Moreover, all factors that may influence the audit risk should be identified. This identification can help guide the reforms to improve the functioning of the financial market.Originality/valueThis study can enhance knowledge and understanding on how motivational and environment factors influence the audit risk. Using data from the Tunisian market, this work fills a research gap by examining the audit risk and identifies a new governance risk index. The specificity of the country where the study is elaborated refers to its accurate “revolutionary” transitional phase. Tunisia aims to enhance economic growth and to establish general strategic governance of the country, particularly strategic governance of companies.
The cynical subordinate: exploring organizational cynicism, LMX, and loyalty
Authors: Scott Kristyn A. , Zweig David 
Published: February 2020

PurposeAdopting a social exchange framework, this article examines the relationship between organizational cynicism and leader–member exchange (LMX) using two different methodologies.Design/methodology/approachStudy 1 utilizes a longitudinal panel design (N = 291) to examine the reciprocal relationships between organizational cynicism and LMX over time. Study 2 (N = 348) positions loyalty as a possible mechanism through which organizational cynicism might impair LMX.FindingsStudy 1 provides evidence for the existence of some reciprocity in the relationships between organizational cynicism and LMX; however, organizational cynicism appears to be a stronger predictor of LMX than the obverse. The results of Study 2 suggest that cynical employees are less loyal to their supervisors, and this cynicism can interfere with the reciprocity process inherent in the creation and maintenance of high-quality social exchanges at work.Originality/valueThis is the first study to examine the relations between organizational cynicism and LMX in a longitudinal design. Additionally, the inclusion of loyalty and demonstration that organizational cynicism impacts loyalty to supervisors negatively represents a novel direction in organizational cynicism research.
Role of integration in scaling of an e-Government project
Authors: Anand Ambuj , Vaidya Sanjiv D. , Sharahiley Sanawi M. 
Published: February 2020

Purpose
Scaling is an important concern in the management of information systems projects. E-Government projects are no exception to the challenges of scaling. The problem is more severe because of a large and diverse population of target users and more crucial because of the vulnerability of the target population in case of failure of such initiatives (in projects, such as public distribution system of food). In spite of a significant awareness of its importance among implementers, scaling still remains a challenge. This paper aims to examine this important issue.

Design/methodology/approach
The case study method has been used to demonstrate the relationship between integration and scaling of e-Government projects. This study uses analytic generalization from field case as a method to theorize a broad framework for the integration of information and communications technology projects. The context of this study is an e-Government project in West Bengal, India. The selection of the case involved theoretical sampling apart from considerations for the possibility of access to the project and its appropriateness with respect to the topic under study.

Findings
Five different levels of integration in e-Government projects, namely, interface, data, electronic communication, application, and knowledge, have been identified. Further, it has been demonstrated that each of these integration mechanisms impacts scaling of e-Government projects. Also, the nature of the impact has been identified.

Originality/value
This paper demonstrates the impact of integration on the scaling of e-Government projects. It analyzes the phenomenon of integration in terms of five different levels. All the levels of integration impact scaling of e-Government projects in different ways.
Epigenetics in ecology and evolution
Authors: Herrel Anthony , Joly Dominique , Danchin Etienne 
Published: February 2020

Abstract

The discovery of the multidimensional nature of the inherited information carried by the epigenome and the characterization of its intra‐ and intergenerational dynamics have profoundly changed our understanding of the functioning of biological organisms and the origins of phenotypic diversity.

This has raised considerable interest in the study of epigenetics which is emerging as a ‘missing link’ between environmental and phenotypic variation.

Recent discoveries have provided important insights into the mechanisms of phenotypic plasticity, inheritance and adaptation; key concepts at the crossroads of individual‐centred approaches (that mostly study proximate mechanisms); and supra‐individual ones (that mostly study ultimate processes).

In this context, epigenetics emerges as a major source of inquiry for the study of ecological and evolutionary dynamics. This special feature provides an overview of the role of epigenetics in ecology and evolution.
The Limits of Homeownership: Racial Capitalism, Black Wealth, and the Appreciation Gap in Atlanta

Published: February 2020

AbstractIn the wake of the 2007–08 housing crash, the Black–white wealth gap reached a staggering 20 to 1. Since then, a growing chorus of influential voices has proposed measures to increase the Black homeownership rate as a means to narrow the gap. Others, however, have argued that the uneven racial geography of home price appreciation necessarily restricts the degree to which Black households, in the aggregate, can build wealth via homeownership. We aim to contribute to these debates by theorizing a racial appreciation gap as a central feature of urban housing markets under racial capitalism, and analyzing how neighborhood racial and income characteristics have structured home price appreciation from before the height of the housing boom (2000–03) to its post‐crisis recovery (2014–16). Focusing on the two counties that encompass Atlanta, Georgia, USA—an area famous for Black prosperity—we find that a neighborhood's racial composition has a more salient impact on home price change than its income. Results indicate that when a place is marked as Black, this may itself inhibit home price appreciation, suggesting that an enduring racial appreciation gap may limit the potential for Black homeownership to substantively narrow the racial wealth gap.

Published: February 2020

AbstractObjectiveTo determine the correlation between hospital 30‐day risk‐standardized readmission rates (RSRRs) in elderly adults and those in nonelderly adults and children.Data Sources/Study SettingUS hospitals (n = 1760 hospitals admitting adult patients and 235 hospitals admitting both adult and pediatric patients) in the 2013‐2014 Nationwide Readmissions Database.Study DesignCross‐sectional analysis comparing 30‐day RSRRs for elderly adult (≥65 years), middle‐aged adult (40‐64 years), young adult (18‐39 years), and pediatric (1‐17 years) patients.Principal FindingsHospital elderly adult RSRRs were strongly correlated with middle‐aged adult RSRRs (Pearson R2 .69 [95% confidence interval (CI) 0.66‐0.71]), moderately correlated with young adult RSRRs (Pearson R2 .44 [95% CI 0.40‐0.47]), and weakly correlated with pediatric RSRRs (Pearson R2 .28 [95% CI 0.17‐0.38]). Nearly identical findings were observed with measures of interquartile agreement and Kappa statistics. This stepwise relationship between age and strength of correlation was consistent across every hospital characteristic.ConclusionsHospital readmission rates in elderly adults, which are currently used for public reporting and hospital comparisons, may reflect broader hospital readmission performance in middle‐aged and young adult populations; however, they are not reflective of hospital performance in pediatric populations.

Published: February 2020

AbstractBackgroundLimited data on the efficacy of the additional metformin therapy in patients with type 1 diabetes mellitus (T1DM) under real‐life conditions have been available so far.MethodsPatients aged ≥18 years with a duration of T1DM for at least 1 year were included in this multicenter observational study. Patients with insulin combined with metformin therapy (MET group) were compared with those with insulin therapy only (INS group).ResultsA total of 76 patients in the MET group were compared with 655 patients in the INS group. At baseline, patients with dyslipidemia were more prevalent in the MET group (17.6% vs 9.0%; P = .006), and they also had a higher body mass index (BMI) (21.7 ± 3.2 kg/m2 vs 20.4 ± 2.6 kg/m2; P < .001) than those in the INS group. But glycosylated hemoglobin (HbA1c) and daily insulin dose were not significantly different between the two groups. After 1‐year follow‐up, HbA1c decreased in both groups, while the daily insulin dose decreased in the MET group, but did not change in the INS group (−0.02 IU/kg [−0.16, 0.09] vs 0 IU/kg [−0.09, 0.09]; P = .029). The additional metformin therapy led to no change of BMI and weight in the MET group, while the body weight increased from 53.7 ± 8.6 kg to 55.0 ± 7.9 kg in the INS group (P < .001).ConclusionsMetformin is initiated more in T1DM patients with dyslipidemia or higher BMI in current practice in China. The addition of metformin is effective in maintaining weight and reducing the insulin dosage without improving glycemic control in patients with T1DM.
Spinal ‘flip‐flop’ effect in anorexia nervosa: A case report
Authors: Varotto Alessia , Vitale Valerio , Mansour Mariam , Di Pascoli Lorenza , Iannucci Giuseppe 
Published: February 2020

SummaryAnorexia nervosa is a psychiatric eating disorder related to malnutrition and consequent altered metabolism. A 48‐year‐old female with a history of anorexia in the last 2 years referred to our hospital with spinal pain. She underwent spinal X‐ray and magnetic resonance imaging (MRI) showing multiple vertebral collapses in dorsal and lumbar spine with inversion of normal bone marrow and soft tissue signal in T1‐weighted and STIR images. We describe this case of spinal ‘flip‐flop’ phenomenon, underlining how what seems a technical failure is actually a specific imaging pattern related to the clinical context.

AbstractIntroductionTo evaluate a radiographer‐led peripherally inserted central catheter (PICC) insertion service within an interventional radiology suite using ultrasound and fluoroscopic guidance.MethodsData from 366 consecutive PICC insertions by five trained angiography‐specialized radiographers were prospectively collected over a 12‐month period. For each PICC insertion, patient demographics, including past medical history of cystic fibrosis (CF), number of punctures, vein used, final tip position, contrast administration and screening time were recorded. Institutional review board approval was obtained.ResultsThe overall PICC insertion success rate was 100%. Fifty‐five (15%) had a known medical history of CF. Three hundred and thirty‐one (90%) PICC insertions required a single puncture and 32 (9%) required two punctures. The remaining three insertions required three punctures. The basilic vein was most commonly used (69%) followed by the brachial vein (29%), and the cephalic vein was used only in 2%. Administration of contrast medium was necessary during 27 (7%) PICC insertions. Mean screening time was 10.7 s.ConclusionOur specifically trained, radiographer‐led PICC insertion service proved to be successful. Both straightforward and complex insertions, for example in CF patients could be adequately and efficiently performed.

AbstractIntroductionIn the present study, we aimed to assess whether normal saline injection for sealing the biopsy track is useful in reducing the incidence of pneumothorax after computed tomography (CT)‐guided percutaneous transthoracic lung biopsy (PTLB).MethodsWe retrospectively compared the incidence of pneumothorax in 100 consecutive biopsies (n = 100, group A) that had injection of saline along the track, with historical cohort of same number of consecutive patients who underwent PTLB without injection of saline along the needle track (n = 100, group B). CT‐guided biopsies were performed by coaxial technique and 1–3 ml of saline was injected along the tract. Patient chjmirocteristics, lesion size, location and other baseline pjmirometers were compared. Incidence of pneumothorax and number of patients who underwent catheter drainage of pneumothorax was compared in both groups.ResultsBaseline chjmirocteristics were compjmiroble in both groups. Track sealing with saline was successful in all patients. Pneumothorax rate was 46% for patients in group B and 32% in group A (P < 0.05). Seven patients (7%) had insertion of chest drain for pneumothorax in the group B and only 1% in the group A (P < 0.05). No mortality was observed in both groups. No complications were observed in any of the patients due to saline injection.ConclusionTrack sealing with saline is a simple and safe technique which significantly reduces the incidence of pneumothorax and chest tube insertion after PTLB.
