Authors: Koul Shiva , Ambekar Suhas Suresh , Hudnurkar Manoj 
Published: December 2020

PurposeThe purpose of this paper is to determine, rank and form composite relational factors that impact the millennial consumer’s mind-set when they opt for an access-based subscription of an over-the-top (OTT) platform service. In the competitive rising Indian market of OTT platforms, there is a need to understand what factors drive the subscription of a service for a company strategizing to build up on their customer base or for a company seeking to retain its customers.Design/methodology/approachThe approach includes determining factors that impact the buying behavior of the consumer and have them ranked by the survey participants in order of their importance as a factor in considering a subscription of an OTT platform service. Questionnaire as a method is used for primary data collection in this research. Using “purposive sampling,” participants of the survey were determined based on their age group and current or historic consumption of at least one OTT platform service. The survey was conducted for the millennial viewership from Tier I and Tier II cities that have good internet connectivity over their mobile phones.FindingsThe result of this research is a ranking of factors based on their importance as perceived by the millennial consumers and then form composite factors, which have similarities in responses.Practical implicationsThis research enables the consumers of the information to dwell on the factors that prove to be of comparative importance to the consumer and plan/forecast their strategies and further research studies accordingly.Originality/valueA research along similar lines has been conducted for US-based OTT platforms. However, this research is specific for Indian consumers and platforms and holds significance because of growth in the Indian OTT market.
My supervisor supports me better than the past: integration of social and temporal comparison
Authors: Afshan Gul , Serrano-Archimi Carolina 
Published: December 2020

PurposeDrawing on the self-consistency theory and temporal comparison theory, this study hypothesize that relative perceived supervisor support may positively affect voice behaviour and negatively affect relationship conflict with a supervisor. This relationship happens through the underlying process of supervisor-based self-esteem acts as an underlying mechanism. But, such a relationship would be constrained by the value of temporal perceived supervisor support with high temporal perceived supervisor support strengthen this relationship as compared to low temporal perceived supervisor support.Design/methodology/approachDyad data from 338 samples of employees nested within 50 supervisor workgroups from non-profit firms operating in three different cities in Sindh Pakistan were taken.FindingsData analysis showed that employees with a high perception of relative perceived supervisor support engaged in voice behaviour and restrain themselves from the relationship conflict. The supervisor-based self-esteem derived from supervisor support played the role of mediating this relationship. Moreover, temporal perceived supervisor support not only moderated the path between relative perceived supervisor support and supervisor-based self-esteem also the mediational strength of supervisor-based self-esteem in relative perceived supervisor support and voice behaviour and relationship conflict.Practical implicationsIt is crucial to integrate social comparison in organizational support theory to view the supervisor–subordinate relationship beyond dyad. Managers should understand social comparison processes in which employees engage in to know how it affects various work attitudes and behaviours.Originality/valueGiven the importance of supervisor–subordinate relationships, the authors extend and build on the concept of social and temporal organizational support to supervisor support. The study is novel in studying such relationship and contribute to the supervisory support relationship literature beyond dyadic level.
Leader, “know yourself”: bringing back self-awareness, trust and feedback with a theory O perspective
Authors: Crook Ngaio , Alakavuklar Ozan Nadir , Bathurst Ralph 
Published: December 2020

PurposeThis paper explores how leaders identify their roles and selves when they lead change in a dynamic organizational context.Design/methodology/approachUsing a qualitative approach, ten ICT leaders participated in semi-structured interviews depicting their experiences of change. A thematic method of interpretative analysis was used to develop findings, supported by Theory U as a conceptual tool for leadership self-awareness.FindingsLeaders struggle with organizational constraints and boundaries, specifically the complexities that form and limit their leadership underpinned by unrealistic expectations due to the construction of romanticized heroic leadership. While these restrictions lead to feelings of detachment of leaders from their organizations, leadership development exists in the acts of letting go of old behaviors, and welcoming emergence and experimentation by trusting more.Research limitations/implicationsThis study may be limited by its small sample and the use of one framework to make sense of the leaders' experience of change. It confirms that change can challenge organizing norms and how leadership is identified.Practical implicationsDespite the feeling of detachment from their organizations, developing greater self-awareness, being open to new ideas and trusting more can bring about better organizational outcomes, which is represented with Theory O as a contribution both for theory and practice.Originality/valueThis study illustrates (1) leaders' inner work or personal experience of change, and (2) how improvement of self-awareness can contribute to the involvement of leaders to the change process. Based on self-awareness, trust and feedback relationship, this study suggests a new practical and conceptual tool called Theory O by advancing Theory U.

PurposeSevere airborne particulate pollution frequently occurs over the North China Plain (NCP) region in recent years. To better understand the characteristics of carbonaceous components in particulate matter (PM) over the NCP region.Design/methodology/approachPM samples were collected at a typical area affected by industrial emissions in Handan, in January 2016. The concentrations of organic carbon (OC) and elemental carbon (EC) in PM of different size ranges (i.e. PM2.5, PM10and TSP) were measured. The concentrations of secondary organic carbon (SOC) were estimated by the EC tracer method.FindingsThe results show that the concentration of OC ranged from 14.9 μg m−3to 108.4 μg m−3, and that of EC ranged from 4.0 μg m−3to 19.4μg m−3, when PM2.5changed from 58.0μg m−3to 251.1μg m−3during haze days, and the carbonaceous aerosols most distributed in PM2.5rather than large fraction. The concentrations of OC and EC PM2.5correlated better (r= 0.7) than in PM2.5−10and PM>10, implying that primary emissions were dominant sources of OC and EC in PM2.5. The mean ratios of OC/EC in PM2.5, PM2.5–10and PM>10were 4.4 ± 2.1, 3.6 ± 0.9 and 1.9 ± 0.7, respectively. Based on estimation, SOC accounted for 16.3%, 22.0% and 9.1% in PM2.5, PM2.5–10and PM>10respectively.Originality/valueThe ratio of SOC/OC (48.2%) in PM2.5was higher in Handan than those (28%–32%) in other megacities, e.g. Beijing, Tianjin and Shijiazhuang in the NCP, suggesting that the formation of SOC contributed significantly to OC. The mean mass absorption efficiencies of EC (MACEC) in PM10and TSP were 3.4 m2g−1(1.9–6.6 m2g−1) and 2.9 m2g−1(1.6–5.6 m2g−1), respectively, both of which had similar variation patterns to those of OC/EC and SOC/OC.

ABSTRACTAngle domain common image gathers are crucial for seismic applications such as the migration velocity analysis and amplitude variation with angle analysis. Angle domain common image gathers are the gather of reflection coefficients when seismic waves incident at different angles on the same image point. The curvature of gathers can be used to update the migration velocity model. The amplitude variation of gathers characterizes different rock properties. Estimating the wavefield propagation direction is the most important step in the process of generating angle domain common image gathers. The wavefront propagation direction is perpendicular to the wavefront. Accurately estimating the wavefield propagation direction is crucial for calculating the reflection angle. Existing methods cannot provide the propagation direction with the high angular resolution when the subsurface structure is complex, meaning overlapped wave events exist. We propose a new method to overcome this problem. The proposed method separates overlapped waves with a directional filter bank after the up‐going and down‐going wavefield decomposition. Then, we apply the Poynting vector method to decomposed wavefield slices to determine the propagation directions of corresponding wavefield components. The key feature of the proposed method is that it does not require spatial local windows, and it is computationally efficient. Numerical tests demonstrate that our proposed method can accurately obtain the propagation direction of seismic waves in a wavefield including overlapped waves. The angle domain common image gathers generated using our proposed method have improved image quality with more accurate amplitudes and less noise compared with the angle domain common image gathers produced by the conventional Poynting vector method. It means our proposed method provides high‐quality prestack angle gathers for seismic attribute analysis.
Legacies of civil wars: A 14‐year study of social conflicts and well‐being outcomes in farming economies

Published: December 2020

AbstractCommunity processes to address fractured social relationships and well‐being remain the least examined dimensions in studies of legacies of civil wars. This article addresses these limitations by analyzing how the wartime and postwar generations have negotiated the legacies of the civil war (1976–1992) in a farming economy region in Mozambique. Based on a 14‐year (2002–2015) study of community courts in Mozambique, we analyzed the types of social conflicts and the associations with gender, age, risk factors, self‐described health impairments, and the timing of farming activities. We identifiedn = 3,456 participants and found that perennial sources of disputes were related to family formation and maintenance, defamation, accusations of perpetration of serious civil wartime violations, mistrust, debts, and domestic violence. Furthermore, conflict relations were associated with gender, age, risk factors, and health problems. This study concludes that civil wars have lasting multifaceted legacies, but generational tensions, availability of community institutions, and economic resources shape social relationships and well‐being outcomes while averting revenge cycles among civilian war survivors.

Published: December 2020

AbstractAimThe internet has gained popularity as a health information source for patients. YouTube is one of the biggest platforms used worldwide. Several studies showed that quality of the information on YouTube videos for patient information is poor. This study aimed to evaluate the content and quality of YouTube videos, as a source of patient information for fibromyalgia (FM).MethodsIn this cross‐sectional study, a YouTube search with the keyword "fibromyalgia" was performed, and the first 200 videos were listed according to relevancy. Advertisements, duplicate videos, videos in languages other than English, and videos without audio were excluded. Video features (number of "likes", "dislikes", views, length of video), and source of upload were recorded. DISCERN and Journal of the American Medical Association (JAMA) benchmark criteria were used for quality analysis. Video quality was assessed according to the source of upload and video features. The correlation analysis was performed between video features, JAMA, and DISCERN scores.ResultsA total number of 102 videos were analyzed. The most common source of upload was physicians and majority of the content (55.8%) was about symptoms and treatment. Mean DISCERN and JAMA scores were 35.7 and 2.2, respectively. These scores were highest in videos uploaded by physicians (52.7 and 2.6, respectively). There is a positive correlation between the duration of the video, DISCERN, and JAMA scores.ConclusionThe majority of YouTube content has poor quality. Health professionals should be aware of the importance of health‐related information on YouTube and provide high‐quality accurate and up‐to‐date content.

AbstractObjectivesThe MONARCA I and II trials were negative but suggested that smartphone‐based monitoring may increase quality of life and reduce perceived stress in bipolar disorder (BD). The present trial was the first to investigate the effect of smartphone‐based monitoring on the rate and duration of readmissions in BD.MethodsThis was a randomized controlled single‐blind parallel‐group trial. Patients with BD (ICD‐10) discharged from hospitalization in the Mental Health Services, Capital Region of Denmark were randomized 1:1 to daily smartphone‐based monitoring including a feedback loop (+ standard treatment) or to standard treatment for 6 months. Primary outcomes: the rate and duration of psychiatric readmissions.ResultsWe included 98 patients with BD. In ITT analyses, there was no statistically significant difference in rates (hazard rate: 1.05, 95% CI: 0.54; 1.91, p = 0.88) or duration of readmission between the two groups (B: 3.67, 95% CI: −4.77; 12.11, p = 0.39). There was no difference in scores on the Hamilton Depression Rating Scale (B = −0.11, 95% CI: −2.50; 2.29, p = 0.93). The intervention group had higher scores on the Young Mania Rating Scale (B: 1.89, 95% CI: 0.0078; 3.78, p = 0.050). The intervention group reported lower levels of perceived stress (B: ‐7.18, 95% CI: −13.50; −0.86, p = 0.026) and lower levels of rumination (B: −6.09, 95% CI: −11.19; −1.00, p = 0.019).ConclusionsSmartphone‐based monitoring did not reduce rate and duration of readmissions. There was no difference in levels of depressive symptoms. The intervention group had higher levels of manic symptoms, but lower perceived stress and rumination compared with the control group.

AbstractPurposeTo investigate the ultrastructure of the cleavage plane of human cornea after liquid‐bubble‐prepared tissue for Descemet’s membrane endothelial keratoplasty (DMEK).MethodsExperimental study with scanning electron microscopy (SEM) and block‐face SEM of 18 corneal specimens. Fresh human research donor corneoscleral discs (n = 12) were prepared with liquid‐bubble technique or examined as untreated controls (n = 3). In addition, Descemet’s membrane samples, n = 3, were obtained in DMEK surgery.ResultsThe cleavage plane after liquid‐bubble Descemet’s membrane (DM) preparation was consistently located between interfacial matrix and posterior stromal collagen lamellae, providing a largely smooth surface exposing the amorphous interfacial zone without any significant amounts of adherent stromal remnants. No demarcation of a distinct pre‐DM layer could be detected.ConclusionThe DMEK graft preparation performed by liquid‐bubble technique showed a smooth cleavage plane and could not reveal any demarcation of a distinct pre‐DM layer.

AbstractTherapeutic options are urgently needed for non‐alcoholic fatty liver disease (NAFLD), but development is time‐consuming and costly. In contrast, drug repurposing offers the advantages of re‐applying compounds that are already approved, thereby reducing cost. Acetylsalicylic acid (ASA) and pentoxifylline (PTX) have shown promise for treatment of NAFLD, but have not yet been tested in combination. Guinea pigs were fed a high‐fat diet for 16 weeks and then continued on the diet while being treated with ASA, PTX or ASA+PTX for 8 weeks. Chow‐fed animals served as healthy controls. Guinea pigs were CT scanned before intervention start and at intervention end. Animals without steatosis (ie NAFLD) at week 16 were excluded from the data analysis. ASA and PTX alone or in combination did not improve hepatic steatosis, ballooning, inflammation or fibrosis nor did the treatments affect liver enzymes (aminotransferases and alkaline phosphatase) or circulating lipids. Liver triglyceride levels, relative liver weight and hepatic mRNA expression of monocyte chemoattractant protein 1, interleukin 8 and platelet‐derived growth factor b were nominally decreased. Thus, in the current study, treatment with ASA and PTX alone or in combination for 8 weeks did not ameliorate NASH or hepatic fibrosis in guinea pigs.

AbstractAimTo determine the effect of whey protein plus vitamin D supplementation combined with progressive resistance training (PRT) on glycaemic control, body composition, muscle function and cardiometabolic risk factors in middle‐aged and older adults with type 2 diabetes (T2D).Materials and MethodsIn this 24‐week, randomized controlled trial, 198 overweight/obese adults (aged 50–75 years) with T2D undertook PRT (2‐3 days/week) with random allocation to whey protein (20 g each morning plus 20 g postexercise) plus vitamin D3 (2000 IU/day) (PRT + ProD, n = 98) or no supplementation (PRT, n = 100). Primary outcomes were HbA1c and homeostatic model assessment‐2 of insulin resistance (HOMA2‐IR). Secondary endpoints included fasting plasma glucose (FPG), body composition, muscle strength, physical function, blood pressure, blood lipids and inflammatory markers.ResultsAt 24 weeks, supplementation did not enhance the effects of PRT on HbA1c (mean absolute change: PRT + ProD −0.10% [95% CI, −0.24%, 0.05%] vs. PRT −0.17% [95% CI, −0.32%, −0.03%], p = .322) or HOMA2‐IR (PRT + ProD −0.12 [95% CI, −0.27, 0.03] vs. PRT −0.03 [95% CI, −0.14, 0.09], p = .370). There were also no significant between‐group differences for the mean changes in the secondary outcomes, except that FPG improved in PRT versus PRT + ProD (net difference, 0.6 mmol/L [95% CI, 0.1, 1.0], P = .018), while interleukin IL‐10 (61% [95% CI 31%, 92%], P < .001), tumour necrosis factor‐α (16% [95% CI, 3%, 29%], p = .015) and 30‐s sit‐to‐stand performance (number, 1.0 [95% CI, −0.05, 1.5], p = .047) increased in PRT + ProD versus PRT.ConclusionsIn older overweight/obese adults with T2D, daily whey protein plus vitamin D supplementation did not augment the effects of PRT on measures of glycaemic control, body composition, muscle strength or cardiometabolic risk factors.

AbstractAimsTo compare different treatments for non‐alcoholic steatohepatitis (NASH) and todetermine an effectiveness hierarchy.Materials and MethodsWe conducted a systematic review and Bayesian network meta‐analysis including randomized controlled trials or prospective trials with at least 6 months' follow‐up and histologically proven NASH in adult participants. Monte Carlo simulations were performed, each generating 10 000 data points, and results are reported as medians and 95% credibility intervals (CrIs). A meta‐regression was conducted to find the effects of body mass index (BMI) decrement or reduction of homeostatic model assessment of insulin resistance (HOMA‐IR) index on non‐alcoholic fatty liver disease activity score (NAS) change.ResultsThe review identified 48 eligible trials comprising 2356 adults (55.6% men). Data were pooled using a random‐effects model. The most effective treatments in terms of NAS reduction per semester were pioglitazone and Roux‐en‐Y gastric bypass (RYGB; −1.50 [95% CrI −2.08, −1.00] for pioglitazione and −1.00 [95% CrI −1.70, −0.32] for RYGB). Pioglitazone was also the best therapy for steatosis and lobular inflammation reduction. RYGB was the best treatment for hepatocellular ballooning reduction, whereas antioxidants appeared to be best for fibrosis improvement. For each 1% decrement in BMI, NAS was reduced by 1.3% (β = 1.28%, P = 0.01). Conversely, a 1% reduction of HOMA‐IR index reduced NAS by 0.3% (β = 0.31%, P < 0.001). Treatments that were regarded as promising, such as elafibranor, simtuzumab, selonsertib, cenicriviroc, obeticholic acid and liraglutide, did not reduce either NAS or liver fibrosis significantly.ConclusionsPioglitazione and RYGB are the most effective therapies for NASH. Antioxidants may be effective in reducing liver fibrosis. Weight loss and improvement of hepatic insulin resistance are promising approaches in the treatment of NASH.
