The democratization of intangible luxury
Authors: Ramadan Zahy 
Published: May 2019

PurposeThe notion of luxury has changed due to the democratization and the fast adoption pace of intangible luxury service providers embedding voice-controlled assistants. In particular, Amazon’s Echo Look is expected to further democratize luxury services and consumer experience; indeed, this camera-based device acts as a personal consultant as it provides fashion advices based on the pictures of its users. Nonetheless, as the Echo Look proliferates the market, concerns around its potential disruption to the marketplace alongside usage-related issues, such as privacy, will arise. The paper aims to discuss these issues.Design/methodology/approachThe research adopted an exploratory approach using elite interviewing. The sample included 17 experts in the fields of digital marketing, fashion consulting, information technology security and retailing.FindingsThe study pioneers the discussion on how interactive voice-activated assistant (IVA) devices can potentially outweigh concerns around safety and privacy through providing luxury-like personalized services. To that end, the Echo Look device was taken as the key example based on the unique features and benefits it provides to its users, namely, in being perceived as a personal fashion consultant.Originality/valueThe literature on intangible luxury based on IVA devices is still nascent. This study fills a considerable gap in the literature related to retailers’ technological innovations aimed at democratizing luxury-like personalized experiences.
Probing the role of psychosocial career mechanisms in the harmonious work passion-career satisfaction link
Authors: Coetzee Melinde , Bester Marais Salemon 
Published: May 2019

PurposeThe purpose of this paper is to explore the association of harmonious work passion with career satisfaction, while probing the mediating role of employees’ psychological career resources and career preoccupations as important psychosocial career mechanisms in this association.Design/methodology/approachThis paper is a cross-sectional quantitative study comprising a sample of (n= 550) employees in various South African organisations.FindingsThe current study found that individuals’ career preferences, career drivers, career harmonisers and career adaptation preoccupations are dynamic mechanisms that regulate the link between harmonious passion and career satisfaction.Research limitations/implicationsThe study is located in South Africa and was cross-sectional in design. Generalisation to other occupational contexts and establishing cause-effect relations were not possible.Practical implicationsThis paper demonstrates the usefulness of harmonious work passion as an additional positive psychological construct in understanding the psychosocial motivational career mechanisms that drive employees’ career satisfaction. The mediating role of certain psychological career resources (i.e. flexible career preferences, career drivers and career harmonisers) and career adaptation preoccupations in the link between employees’ harmonious passion and career satisfaction need to be considered in career management support practices.Social implicationsThis paper demonstrates the growing need to better understand the psychosocial mechanisms that influence employees’ career satisfaction.Originality/valueThe study contributed new insights that extend theory and research on the harmonious work passion phenomenon in relation to important career constructs in the work-career context by means of self-determination theory.
The role of job crafting and knowledge sharing on the effect of transformational leadership on innovative work behavior
Authors: Afsar Bilal , Masood Mariam , Umrani Waheed Ali 
Published: May 2019

Purpose
The purpose of this paper is to examine the effect of transformational leadership on an employee’s innovative work behavior through job crafting. In addition, the study explores the moderating effect of knowledge sharing behavior in the relationship between transformational leadership and innovative work behavior.

Design/methodology/approach
A quantitative and cross-sectional approach was used to collect data. Data were collected from 325 subordinates and 126 supervisors working in the hotel industry. Subordinates were asked to rate transformational leadership style of their respective supervisors and their own job crafting and knowledge sharing behaviors. Supervisors were asked to rate innovative work behavior of their respective subordinates.

Findings
The results showed that job crafting behaviors (increasing structural job resources, increasing social resources and increasing job challenges) mediated the effect of transformational leadership on an employee’s innovative work behavior. Moreover, knowledge sharing moderated the relationship between transformational leadership and innovative work behavior.

Practical implications
Organizations may reap the benefits of an innovative workforce by selecting, nurturing and developing transformational leaders who facilitate employees to proactively craft a challenging and resourceful work environment.

Originality/value
This is the first study to test the mediating effect of job crafting behaviors on the relationship between transformational leadership and innovative work behavior.
The evolution of the English street gang
Authors: Pitts John 
Published: May 2019

Purpose
The purpose of this paper is to consider what the author might call the evolution of the evolutionary argument about gangs and, while acknowledging its explanatory power, suggests that gangs may develop in very different ways depending on the available opportunities, pre-existing forms of criminality in the areas in which gangs emerge and global change.

Design/methodology/approach
It is based on a review of the relevant literature and interviews with purposive samples of research, criminal justice and social welfare professionals and young people involved in or affected by gang crime. Findings were triangulated with data held by the police and other public authorities.

Findings
The term “street gang” includes a wide variety of groupings all of which are involved in some form of crime but with differential levels of organisation and commitment to purely instrumental goals. Gangs may form but not necessarily evolve. Gangs appear to develop in very different ways depending on the available opportunities, pre-existing forms of criminality in the areas in which they emerge and global changes in drugs markets.

Originality/value
The originality of the paper consists in its interrogation of the concept of “gang evolution” and its discussion of the variety of forms and evolutionary trajectories of gangs.
Psychology perspectives on community vengeance as a terrorist motivator: a review
Authors: Bowman Grieve Lorraine , Palasinski Marek , Shortland Neil 
Published: May 2019

PurposeThe purpose of this paper is to explore the concept of vengeance as a terrorist motivator.Design/methodology/approachThe paper takes a community psychological perspective to examine vengeance in a number of forms. First covering “blood vengeance”, it then examines vigilantism and death squads as functional examples of vengeful entities, as well as the morality of vengeance and the impact of propaganda on vengeance as a terrorist motivator. Finally, both group processes and individual factors relating to the promotion and use of vengeance in terrorism are covered.FindingsVengeance can be conceptualised in a number of ways: as a predisposing factor to individual involvement, a factor that contributes to keeping the movement “bound” together (but which can also negatively affect the group’s strategic logic), a factor in the escalation of violent activity through vigilantism, retribution and retaliation which can result in a perpetuation of a cycle of violence, and as a moral mandate that is ideologically rationalised and justified, with perceptions of righteousness and obligation inherent to it.Research limitations/implicationsThe presented research is limited by the scarcely available data.Practical implicationsEfforts should be made to defuse vengeful motivations by tapping into collective identities of communities and incorporating multicultural values.Social implicationsPolicy makers should be wary of scoring populist scores by ridiculing out-group/religious elements as that creates potential for vengeful terror attacks.Originality/valueThe paper offers insights by renewing the neglected perspective of vengeance in terrorism research.
Forward plane‐wave electromagnetic model in three dimensions using hybrid finite volume–integral equation scheme
Authors: Bello Musa A. , Guo Rongwen , Liu Jianxin 
Published: May 2019

ABSTRACTWe present a concept of the hybrid finite volume–integral equation technique for solving Maxwell's equation in a quasi‐static form. The divergence correction was incorporated to improve the convergence and stability of the governing linear system equations which pose a challenge on the discretization of the curl–curl Helmholtz equation. A staggered finite volume approach is applied for discretizing the system of equations on a structured mesh and solved in a secondary field technique. The bi‐conjugate gradient stabilizer was utilized with block incomplete lower‐upper factorization preconditioner to solve the system of equation. To obtain the electric and magnetic fields at the receivers, we use the integral Green tensor scheme. We verify the strength of our hybrid technique with benchmark models relative to other numerical algorithms. Importantly, from the tested models, our scheme was in close agreement with the semi‐analytical solution. It also revealed that the use of a quasi‐analytical boundary condition helps to minimize the runtime for the linear system equation. Furthermore, the integral Green tensor approach to compute at the receivers demonstrates better accuracy compared with the conventional interpolation method. This adopted technique can be applied efficiently to the inversion procedure.
It's about quality
Authors: Butts Jeffrey A. , Pfaff John 
Published: May 2019

Research SummaryThe youth justice system in the United States has always depended on nongovernmental organizations to provide some of the services, supports, and sanctions for youth after juvenile court adjudication. As the use of state‐operated youth confinement declined in recent years, primarily as a result of falling rates of serious juvenile crime, the relative importance of private facilities increased. The number of juveniles held in privately operated secure confinement facilities is now larger than the number confined in state institutions.Policy ImplicationsShould policy makers be concerned about a gradual shift from public to private secure facilities? Certainly, some private facilities are poorly managed, neglectful, and even abusive, but the same has always been true for some public facilities. Effective policy and practice should be focused on the quality of interventions rather than on their financial auspices. Quality youth justice systems (a) limit the use of confinement to cases where it is objectively necessary, (b) ensure the health and safety of all confined youth, (c) provide effective treatments and developmentally appropriate programming, and (d) continually monitor and evaluate their effectiveness. These goals apply to all forms of secure confinement regardless of financing or organizational configuration.

Published: May 2019

BackgroundDeriving novel treatments for alcohol use disorders (AUDs) is of critical importance, as existing treatments are only modestly effective for reducing drinking. Two promising strategies for treating AUDs include cognitive bias modification (CBM) and transcranial direct current stimulation (tDCS). While each strategy has shown positive results in reducing drinking or alcohol‐related constructs (e.g., craving), initial tests of the combination of CBM and tDCS have shown mixed results. The present study investigated the degree to which combining CBM and tDCS (2.0 mA anodal current over F10) could reduce alcohol approach biases and alcohol consumption.MethodsSeventy‐nine at‐risk drinkers were randomized to 1 of 4 conditions in a 2 × 2 factorial design: verum CBM/verum tDCS, verum CBM/sham tDCS, sham CBM/verum tDCS, or sham CBM/sham tDCS. Participants completed a baseline assessment of alcohol approach bias and drinking quantity/frequency (i.e., drinks per drinking day [DDD] and percent heavy drinking days [PHDD]), 4 sessions of combined CBM and tDCS, and follow‐up assessments of approach bias and alcohol consumption.ResultsResults indicated that while participants did demonstrate significant alcohol approach biases at baseline, neither CBM, tDCS, nor the interaction reduced the bias at the follow‐up. In addition, there was evidence of a trend toward reducing DDD from baseline to the 1‐week/1‐month follow‐ups, but there was no significant effect of the intervention on either DDD or PHDD.ConclusionsThese results partially replicated null results presented in similar CBM/tDCS trials and suggest that this combination, at least with anodal stimulation over dorsolateral or inferior frontal sites, may have limited utility to reduce drinking.
Improved Detection of Epigenomic Marks with Mixed-Effects Hidden Markov Models

Published: May 2019

Abstract
Chromatin immunoprecipitation followed by next-generation sequencing (ChIP-seq) is a technique to detect genomic regions containing protein-DNA interaction, such as transcription factor binding sites or regions containing histone modifications. One goal of the analysis of ChIP-seq experiments is to identify genomic loci enriched for sequencing reads pertaining to DNA bound to the factor of interest. The accurate identification of such regions aids in the understanding of epigenomic marks and gene regulatory mechanisms. Given the reduction of massively parallel sequencing costs, methods to detect consensus regions of enrichment across multiple samples are of interest. Here, we present a statistical model to detect broad consensus regions of enrichment from ChIP-seq technical or biological replicates through a class of zero-inflated mixed-effects hidden Markov models. We show that the proposed model outperforms existing methods for consensus peak calling in common epigenomic marks by accounting for the excess zeros and sample-specific biases. We apply our method to data from the Encyclopedia of DNA Elements and Roadmap Epigenomics projects and also from an extensive simulation study.

Published: May 2019

AbstractHuman impacts can affect the soil properties through erosion and leaching, the ecosystem functions and, consequently, the capacity of a forest to regenerate. Here, we determine the effects of forest disturbance and succession on selected soil chemical properties using two different approaches, before‐after‐control‐impact (BACI) and space‐for‐time (SFT) substitution, and the threatened Atlantic Forest biome as model. We assessed with BACI the long‐term (37‐year) effects of clear cutting on soil properties by comparing data from two topsoil surveys (1978–2017) divided into two treatments: a preserved old growth forest (control) and an adjacent forest that was experimentally cleared with full tree removal (clear‐cut). We examined with SFT the relationship between stand age and soil properties using soil data from three old growth and 13 s growth forests ranging from 7 to 33 years. We found no significant differences between treatments for any soil property or significant changes in phosphorus, potassium, and calcium + magnesium over time. In contrast, pH increased and aluminum decreased in both areas. No relation was found between forest age and most of soil properties, with the exception of potassium which returned to old growth forest levels after 20 years of natural succession, and pH. BACI indicated that deforestation of old growth forest caused no significant effects on soil chemical properties after 37 years of regeneration. SFT demonstrated that soil properties did not change significantly during forest regeneration on formerly disturbed lands. Our findings indicate that natural nutrient‐depleted lowland forests were overall resistant to deforestation followed by passive regeneration at landscape scale.Abstract in Portuguese is available with online material.

Published: May 2019

Background and purposeC‐type lectin‐like receptor 2 (CLEC‐2) has prominent involvement in platelet activation, which is increased in coronary heart disease and acute ischaemic stroke (AIS) and is associated with stroke progression and stroke prognosis. Here, the aim was to examine the prognostic value of CLEC‐2 in death and vascular event recurrence in AIS patients.MethodsIn all, 352 patients with AIS were studied prospectively. All patients were followed up for 1 year. Death for all vascular events and a combination of death and vascular diseases (recurrent stroke, myocardial infarction, hospitalized and treated angina, hospitalized and treated peripheral arterial disease) were recorded.ResultsDuring 1 year of follow‐up, 46 patients (14.2%) experienced death or combined end‐points (23 death and 46 combined end‐points). Plasma CLEC‐2 (pCLEC‐2) was significantly associated with an increased risk of death and combined events of death and vascular diseases after adjusting for age, sex, history of hypertension, diabetes mellitus and coronary artery disease, and National Institutes of Health Stroke Scale scores. Each 1 SD higher log‐transformed pCLEC‐2 was associated with a 4.27‐fold (hazard ratio 4.27, 95% confidence interval 1.71–10.65) increased risk for death and a 2.42‐fold increased risk for combined end‐points (hazard ratio 2.42, 95% confidence interval 1.52–3.86). The optimal cut‐off point of pCLEC‐2 for predicting death was 184.38 pg/ml.ConclusionsHigher pCLEC‐2 levels at admission were associated with increased risk of death and combined events of death and vascular diseases in patients with AIS, which indicated that pCLEC‐2 is an important prognostic factor for AIS.

AimsIt is recommended that tumour budding in colon cancer be counted on haematoxylin and eosin‐stained sections in a hotspot area of 0.785 mm2 with a ×20 microscope objective. However, tumour buds may be difficult to visualise on haematoxylin and eosin‐stained sections, and counting in such a limited area may result in overestimation in cases with focal budding. The aim of this study was to assess the contributions of various factors to improving tumour budding risk stratification: increasing the number of fields counted, using cytokeratin immunostaining, and recording proliferation, the apoptotic index and the emperipoletic index in tumour buds.Methods and resultsWe created an exploratory series composed of 172 cases of colon cancer in all stages, and we analysed the survival probability in a second cohort of 158 stage I–II patients. According to our results, counting of budding in 10 fields was the only factor that was significantly correlated with disease‐free survival probability in stage I–II patients [hazard ratio (HR) for high versus low grade of 7.64, 95% confidence interval (CI) 5.54–27.92, P = 0.01; HR for intermediate versus low grade of 3.02, 95% CI 1.54–26.72, P = 0.04). Emperipolesis was frequently observed in tumour buds, whereas the mitotic index and the apoptotic index were extremely low. Although cytokeratin immunostaining increased interobserver concordance, it did not improve the accuracy of tumour budding grading.ConclusionsAccording to our results, counting in 10 fields significantly enhanced the budding grade risk stratification in colon cancer patients, and cytokeratin immunostaining could be reserved as a complementary technique for challenging cases with an inflammatory infiltrate and/or striking fibrosis.

Fitness advantages of the biased use of paired laterally symmetrical penises in an insect

Published: May 2019

AbstractThe evolution of laterality, that is the biased use of laterally paired, morphologically symmetrical organs, has attracted the interest of researchers from a variety of disciplines. It is, however, difficult to quantify the fitness benefits of laterality because many organs, such as human hands, possess multimodal functions. Males of the earwig Labidura riparia (Insecta: Dermaptera: Labiduridae) have morphologically similar laterally paired penises, only one of which is used for inseminating the female during a single copulation bout, and thus provide a rare opportunity to address how selection pressure may shape the evolution of population‐level laterality. Our population studies revealed that in 10 populations, located at 2.23–43.3° north, the right penis is predominantly used for copulating (88.6%). A damaged penis was found in 23% of rare left‐handers, suggesting that the left penis can function as a spare when the right one is damaged. By pairing L. riparia females with surgically manipulated males, we found that males forced to use the right penis outperformed left‐handed males in copulation (the probability of establishing genital coupling during the 1‐hr observation period: odds ratio [OR] of 3.50) and insemination (probability of transferring a detectable amount of sperm: OR of 2.94). This right‐handed advantage may be due to the coiled morphology of the sperm storage organ with a right‐facing opening. Thus, female genital morphology may play a significant role in the evolution of handedness and may have acted as a driving force to reduce penis number in related taxa.
