Exploring jealousy and envy in communal relationship revenge-seeking
Authors: Hancock Tyler , Adams Frank G. , Breazeale Michael , Lueg Jason E. 
Published: July 2020

Purpose
This paper aims to identify the ways that customers respond to customer-to-customer comparisons that may drive loyal customers to engage in undesirable behaviors. The research examines the role that jealousy and envy play in restoring equity through revenge-seeking intentions.

Design/methodology/approach
The study uses survey research methodology. The measurement model is validated using CFA, and hypotheses are tested using structural equation modeling. The mediated relationships are calculated using the bootstrap method, and moderated mediation is calculated by creating estimands to test the effects.

Findings
Customers who feel either jealousy or envy may engage in revenge-seeking behaviors, such as vindictive complaining and negative electronic word-of-mouth (eWOM). Customers who perceive that a firm is unfairly favoring other customers develop feelings of jealousy and betrayal, and this tendency is strengthened when the customer has a high level of prior trust. Customers typically develop envy when their attention and perceptions of inequity center on another customer, rather than on the firm’s actions and anger drives this effect.

Practical implications
Customers can pursue revenge-seeking actions when unfair actions influence the formation of envy and jealousy through the development of perceived betrayal. Companies can focus on the comparisons that customers make to address revenge-seeking and better manage online relationships preemptively.

Originality/value
The paths that customers take to revenge through jealousy and envy are conceptualized in a communal relationship setting and further developed. Further distinctions of jealousy and envy are made, and the role of prior trust in enhancing revenge-seeking is found.
Determinants of management fraud in the banking sector of Ghana: the perspective of the diamond fraud theory
Authors: Avortri Christine , Agbanyo Richard 
Published: July 2020

Purpose
Fraud has become one of the most challenging issues facing the financial sector of most countries globally. These fraudulent transactions have led to loss of huge sums of money to financial institutions, as well as to their depositors. The current crises in the financial sector of Ghana, especially among the Deposit Taking Institutions, has largely been attributed to connected lending and lending to affiliated party institutions which are fraudulent corporate governance issues. This study, therefore, aims to assess the determinants of fraud among management staffs in the banking sector of Ghana.

Design/methodology/approach
This study is anchored on the fraud diamond theory (FDT). Primary data was collected from 120 management staffs of the remaining 23 universal banks in Ghana. Estimation was done using structural equation modelling with maximum likelihood estimation technique.

Findings
Fraudulent activities in the banking sector of Ghana are driven by opportunities, pressure, rationalization and capacity to commit fraud, with capacity being the dominant factor.

Practical implications
The regulator should strictly enforce the structure of shareholding as directed in the corporative governance directive to prevent ownership of a bank in the name of one person or a family, which gives high capacity to the Chief Executive Officers to misuse funds. The offenders should also be punished. Finally, the regulator should improve their supervision.

Originality/value
This study places the FDT into the context of the current banking crises of Ghana. The study therefore goes a long way to guide the regulator and government to formulate and implement policies on shareholding structure of banks.
From mentors to leaders: leader development outcomes for mentors
Authors: Ayoobzadeh Mostafa , Boies Kathleen 
Published: July 2020

PurposeThe present study examines leader development as one of the potential outcomes for mentors and investigates whether the provision of mentoring contributes to developing mentors' leader identity and leader self-efficacy.Design/methodology/approachRelying on a quasi-experimental design, data were collected at four points in time over eight months from a mentor (n = 46) and an equivalent nonmentor group (n = 25). Participants in the mentor group were volunteer mentors from a doctoral mentoring program that was implemented at a large Canadian university.FindingsParticipants in the mentor group experienced a more positive change in leader identity and leader self-efficacy, compared to the participants in the nonmentor group. Further analysis of the participants in the mentor group suggests that the extent to which mentors provide career and psychosocial support explains the growth rate in the development outcomes.Practical implicationsBy documenting benefits of mentoring for mentors, program administrators may be able to recruit mentors who are more engaged in the process. In addition, they can encourage their members to volunteer as mentors to gain leader development outcomes.Originality/valueThis longitudinal study connects the areas of mentoring and leadership development. While the majority of mentoring studies focus exclusively on mentoring outcomes for protégés, the present study shows that mentoring can benefit mentors as well.
The culmination stage of leadership succession
Authors: Mattar Dorine M. 
Published: July 2020

PurposeThis study aims to shed light on employees' emotional status during the culmination stage of leadership succession.Design/methodology/approachAn inductive research design is adopted, relying on the qualitative data collected from semi-structured interviews conducted with participants.FindingsThe qualitative data analysis revealed that subordinates are shocked anytime new leadership practices, contradicting the previous ones that they were used to, are initiated by the successor. Moreover, anger is found to be the dominant negative emotion exhibited by the subordinates during the culmination stage, given that they are nostalgic to the practices of their old transformational leader.Originality/valueThe value of this study lies in its longitudinal qualitative nature, assessing affective response during an organizational change, where subordinates are attempting to digest the change. It adds to the existing literature on emotions during leadership succession, thus assisting people in key managerial positions to better assess the situation and channel their subordinates' negative emotions into a more positive affect while supporting them all the way through.
Enterprise risk management and Solvency II: the system of governance and the Own Risk and Solvency Assessment
Authors: Durán Santomil Pablo , Otero González Luis 
Published: July 2020

Purpose
The purpose of this paper is to analyze how enterprise risk management (ERM), the system of governance and the Own Risk and Solvency Assessment (ORSA) have been boosted with the entry of Solvency II.

Design/methodology/approach
For this analysis, the authors have undertaken a survey of chief risk officers (CROs) working in Spanish insurance companies.

Findings
The results show that Solvency II has definitely promoted ERM in the European insurance industry and improved the system of governance of the insurance companies, and that the perceived value of the ORSA for the companies is higher than the cost. It is clear that the quality of ERM implemented by companies is higher in those that face more complex risks and with greater interdependencies – that is, larger companies, foreign insurers and insurers with several lines of business – but is unaffected by the legal form of the entity (mutual/corporation).

Originality/value
This study conducts primary research with surveys of CROs and develops a measure of the quality of ERM implemented by insurance companies.
The role of efficiency in capital asset pricing: a research on Nasdaq technology sector
Authors: Aygoren Hakan , Balkan Emrah 
Published: July 2020

PurposeThe aim of this study is to investigate the role of efficiency in capital asset pricing. The paper explores the impact of a four-factor model that involves an efficiency factor on the returns of Nasdaq technology firms.Design/methodology/approachThe paper relies on data of 147 firms from July 2007 to June 2017 to examine the impact of efficiency on stock returns. The performances of the capital asset pricing model (CAPM), Fama–French three-factor model and the proposed four-factor model are evaluated based on the time series regression method. The parameters such as the GRS F-statistic and adjusted R² are used to compare the relative performances of all models.FindingsThe results show that all factors of the models are found to be valid in asset pricing. Also, the paper provides evidence that the explanatory power of the proposed four-factor model outperforms the explanatory power of the CAPM and Fama–French three-factor model.Originality/valueUnlike most asset pricing studies, this paper presents a new asset pricing model by adding the efficiency factor to the Fama–French three-factor model. It is documented that the efficiency factor increases the predictive ability of stock returns. Evidence implies that investors consider efficiency as one of the main factors in pricing their assets.
Encouraging engagement: video-conference augmentation of online distance learning environments
Authors: Starr-Glass David 
Published: July 2020

PurposeThe purpose of this reflection on practice is to consider and attempt made by the present author to re-imagine online distance learning (ODL) environments to provide a greater opportunity for learner engagement.Design/methodology/approachODL environments were augmented by video-conferencing to increase dialogue, instructor presence and a sense of instructor care, concern and guidance. The video-conference component was limited time-wise (40 min per weekly module) and aimed at explaining and integrating learning content and activities. The resulting courses were thus augmented and enhanced and not transformed into blended learning courses.FindingsPreliminary feedback from video-conference discussions and learner reflective journals indicates that the innovation was well received by students and contributed significantly to their appreciation, satisfaction and overall engagement.Practical implicationsThe augmentation is simple and effective. It may be an approach that is particularly relevant in designing and facilitating ODL environments in an era of uncertainty, disruption and far-reaching educational changes caused by the COVID-19 pandemic.Social implicationsThe author argues that the introduction of an active learning component has significant implications for learner performance, satisfaction and persistence with distance learning programs.Originality/valueAttempts to increase social presence and engagement are not uncommon in ODL. This particular approach is simple, easily enacted and has a perceived element of originality and innovation that appeals to learners. It is argued that it contributes significant value to the quality and outcomes of the distance learning experience.

Authors: Sierra Jose Manuel , Rodríguez Jose Ignacio , Villazon Marta María , Cortizo Jose Luis , Fernandez Maria del Rocio 
Published: July 2020

Purpose
This paper aims to describe the development of an internal waste-collection device for patients who have undergone a colostomy or ileostomy. Its design is based on devices that have been produced by 3D printing with acrylonitrile butadiene styrene. The aim is to find an alternative to the external bags that these patients currently use and to evaluate the properties of the device produced by additive manufacturing.

Design/methodology/approach
Software for solid modelling has been used, and virtual models allow its visualization and animation, for evaluation, in a simple and fast way. Subsequently, functional prototypes have been developed by a multidisciplinary team, which includes surgeons and engineers, and have been tested to verify their mechanical properties and suitability for function.

Findings
The project has developed a functional design that has been patented and is in the clinical trials phase. This study demonstrates how 3D printing technologies are the perfect complement to accelerate the design process and build functional prototypes at low costs. The experimental tests regarding cytotoxicity, printing orientation, dynamic and static loads and temperature resistance have demonstrated the validity of the proposed device.

Originality/value
A device for internal pouch in colostomized patients has been designed, manufactured by fused deposition modelling and validated.
Too many cooks in the kitchen? The contingent curvilinear effect of shared leadership on multidisciplinary healthcare team innovation
Authors: Mitchell Rebecca , Boyle Brendan 
Published: July 2020

AbstractShared leadership and multidisciplinary teams are advocated for their capacity to develop innovative solutions to important organisational challenges. However, research suggests that the impact of shared leadership is somewhat ambiguous, leading us to propose a curvilinear inverted U‐shaped effect on multidisciplinary team innovation. Furthermore, we posit that this curvilinearity is contingent on awareness of member profession, specifically the salience of professional identity. Using a sample of 60 multidisciplinary healthcare teams, we investigated a model in which shared leadership has a curvilinear effect on innovation contingent on professional salience. Support for our hypotheses attempts to account for ambiguities in the impact of shared leadership and provides guidance for human resource management strategies to enhance multidisciplinary team innovation.
Macrophage activation syndrome in pediatrics: 10 years data from an Indian center
Authors: Pal Priyankar , Bathia Jigna , Giri Prabhas Prasun , Roy Mandira , Nandi Alolika 
Published: July 2020

AbstractAimsMacrophage activation syndrome (MAS) is a dreaded complication of systemic inflammatory diseases and is most commonly seen in systemic juvenile idiopathic arthritis (sJIA). We evaluate the clinical features, laboratory findings and outcomes in pediatric MAS, assess the response to different pharmacological therapies, and finally identify possible factors associated with an unfavorable outcome.MethodsThis is a retrospective analysis of data from patients diagnosed as having MAS, admitted between July 2008 and April 2018 into the Department of Pediatric Rheumatology, Institute Of Child Health Kolkata. The data noted were the clinical and laboratory features, treatment details, responses to therapy and outcomes.ResultsThirty‐one patients were diagnosed as having MAS. Primary illness was sJIA in 26 (84%), systemic lupus erythematosus in 4 (13%) and Kawasaki disease (KD) in 1 (3%). All had fever with varying degrees of multisystemic involvement. Hyperferritinemia was universally present. Pulse methylprednisolone with cyclosporine was used for treating the majority. Ten patients (32%) expired.ConclusionMacrophage activation syndrome is a near fatal complication with protean manifestations and multiorgan dysfunction. Hyperferritinemia is characteristic, higher values being associated with increased mortality. Cases resistant to steroids and cyclosporine had a poor prognosis. Late presentations with multiorgan dysfunction were associated with the poorest outcomes.
pycoalescence and rcoalescence: Packages for simulating spatially explicit neutral models of biodiversity
Authors: Thompson Samuel E. D. , Chisholm Ryan A. , Rosindell James 
Published: July 2020

Abstract

Neutral theory proposes that some macroscopic biodiversity patterns can be explained in terms of drift, speciation and immigration, without invoking niches. There are many different varieties of neutral model, all assuming that the fitness of an individual is unrelated to its species identity. Variants that are spatially explicit provide a means for making quantitative predictions about spatial biodiversity patterns.

We present software packages that make spatially explicit neutral simulations straightforward and efficient. The packages allow the user to customize both dispersal and landscape structure in a wide variety of ways. We provide a Python package pycoalescence and a functionally equivalent R package rcoalescence. In both packages, the core routines are written in C++ and make use of coalescence methods to optimize performance.

We explain the technical details of the packages and give examples for their application, with a particular focus on two scenarios of ecological and evolutionary interest—a landscape with habitat fragmentation, and an archipelago of islands.

Spatially explicit neutral models represent an important tool in ecology for understanding the processes of biodiversity generation and predicting outcomes at large scales. The effort required to implement these complex spatially explicit simulations efficiently has thus far been a barrier to entry. Our packages increase the accessibility of these models and encourage further investigation of the primary mechanisms underpinning biodiversity.

Published: July 2020

ABSTRACTBackground and AimsMany evidence‐based treatments (EBTs) for substance use disorder (SUD) exist, yet few are tailored to Indigenous patients. This trial tested the efficacy of a culturally tailored EBT that combined Motivational Interviewing and the Community Reinforcement Approach (MICRA) versus treatment as usual (TAU).DesignA mixed efficacy/effectiveness randomized controlled trial of MICRA (n = 38) and TAU (n = 41) using a parallel design with follow‐up assessments at 4‐, 8‐, and 12‐ months post baseline.SettingUnited States, reservation‐based outpatient, addiction specialty care treatment program.Participants79 (68% male) American Indian and Alaska Native (AI/AN) Tribal members meeting criteria for SUD and seeking SUD treatment.InterventionsMICRA (individual therapy sessions beginning with MI for 2–3 sessions) compared with TAU (individual and group counseling sessions in a didactic style with Twelve‐Step philosophy and elements of relapse prevention).MeasuresDemographics, percent days abstinent (PDA; the primary outcome at 12months assessed by Form 90D), Inventory of Drug Use Consequences, Alcohol and Drug Use Self‐Efficacy Scale, Native American Spirituality Scale, and SCID‐DSM‐IV‐TR.FindingsThere was no evidence for the benefit of MICRA over TAU (MICRA PDA = 72.63%, TAU = 73.62%, treatment effect: B = −4.04 (SE = 5.47); 95% CI = −14.941, 6.866; BF = 3.44) in the primary outcome. Both groups showed improvements in PDA, SUD severity, and negative consequences from baseline to the 12‐month follow‐up. Neither self‐efficacy nor spirituality were significant mediators of MICRA.ConclusionsThere were no treatment group differences between culturally tailored evidence‐based treatments for substance use disorder and treatment as usual in this randomized controlled trial with American Indian and Alaska Native participants. Nonetheless, participants improved over time on several substance‐related outcomes.

Published: July 2020

Background and ObjectivesPrevious research has shown that alcohol craving is associated with psychiatric comorbidities. However, no population studies have examined the odds of psychiatric disorders in cravers and noncravers. The purpose of this study was to investigate current prevalence rates and odds ratios of psychiatric disorders among alcohol drinkers with and without alcohol craving in a population‐based sample. We also compared four craving groups (cravers with and without alcohol use disorder [AUD], noncravers with and without AUD) for psychiatric comorbidities.MethodsThe study data were drawn from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). A subset of the NESARC sample (N = 22 000) who reported alcohol use during the past 12 months was included. Prevalence rates of psychiatric disorders were compared among current drinkers with alcohol craving (N = 900) and without alcohol craving (N = 21 500).ResultsCravers had higher prevalence rates of current psychiatric disorders than noncravers. Even after adjustment for other psychiatric disorders including AUD, cravers had significantly higher odds of any substance use disorder (adjusted odds ratio [AOR], 9.01), any mood disorder (AOR, 1.78), any anxiety disorder (AOR, 1.86), and any personality disorder (AOR, 1.92) than noncravers. Interestingly, cravers without AUD had even higher rates of any anxiety disorder and any personality disorder than noncravers with AUD.Conclusions and Scientific SignificanceAlcohol craving is associated with a higher prevalence of various psychiatric disorders. These findings suggest that alcohol craving may be related to transdiagnostic features that are present across various psychiatric disorders. (Am J Addict 2021;30:34–42)
Caledonian foreland basin sedimentation: A new depositional model for the Upper Silurian‐Lower Devonian Lower Old Red Sandstone of the Midland Valley Basin, Scotland
Authors: McKellar Zoe , Hartley Adrian J. 
Published: July 2020

AbstractReconstruction of the geological history of orogenic events can be challenging where basins have limited and/or fragmentary preservation. Here, we apply understanding gained from modern analogues to the sedimentological analysis of the succession of Upper Silurian to Lower Devonian Lower Old Red Sandstone (LORS), northern Midland Valley, Scotland, in order to reconstruct the foreland to the Caledonian orogeny. A new depositional model is presented which differs significantly from current understanding. Using facies analysis, grain size distribution and palaeocurrent data a large distributive fluvial system is reconstructed. Three lithofacies and nine sublithofacies are identified, forming fluvial channel and floodplain facies associations. The system was derived from an emerging mountain range in the Caledonian foreland undergoing constant tectonic rejuvenation to produce 9 km of coarse‐grained sediment, exhibiting an overall decrease in thickness towards the west and a large‐scale downstream reduction in grain size. Conglomerate sublithofacies dominate proximal areas in the east where amalgamated fluvial channel facies association is abundant, with a downstream increase in the dominance of floodplain facies. Additionally, observed grain size cyclicity is attributed to a pulsatory tectonic influence. The LORS records the time‐period between the late phases of the Caledonian Orogeny and the onset of post‐orogenic collapse in the mid‐Devonian and the presented model allows improved understanding of the north‐Atlantic Caledonian foreland.
