Investigating the effects of consistent visual identity on social media
Authors: Kaur Harsandaldeep , Kaur Kanwal Roop 
Published: February 2021

Purpose
Although the prominence of social media for companies is widely acknowledged, a close examination of the literature reveals a lack of empirical research pertaining to the effect of consistency specifically on social media. Therefore, the purpose of this paper is to fill the gap in social media communication concerning the effect of consistent visual identity on social media users.

Design/methodology/approach
The study executed an experiment 2 (corporate visual identity condition) × 2 (organization type) between subjects design to map the effects of consistent visual identity on social media users appreciation of the visual identity, attitude toward the company, reputation and intention to commit to a company on social media.

Findings
The results of the study indicated the significant effects of consistent visual identity on social media users over the inconsistent conditions of visual identity on all dependent variables. Furthermore, there were insignificant main effects of organization type on general judgment, credibility, distinctiveness and reputation of the company.

Practical implications
This study presents the effects of consistent visual identity on social media platforms. The research will help marketing academicians, graphic designers and social media practitioners in online marketing by using its practical implications to strategically positioning their corporate brand in a social media environment.

Originality/value
This study provides novel insights on the impact of consistency on social media users. This is the first study to determine the role of consistent visual identity in the social media environment. It thereby adds to the literature of visual identity by developing the sphere of influence of consistency and its effects toward the user’s attitude.
Explaining the comparative perception of e-payment: role of e-shopping value, e-payment benefits and Islamic compliance
Authors: Garrouch Karim F. 
Published: February 2021

Purpose
This study aims to examine three factors affecting the comparative e-payment perception, namely, perceived e-shopping value, e-payment benefits and Islamic Sharia compliance. It verifies an original model explaining the comparative perception of e-payment as a tool to pay online purchases. The newly integrated variables are the perceived compliance of the e-payment with Islamic Sharia, as a moderator, and the perceived e-shopping value, as a predictor. This investigation also tested the mediating role of e-payment benefits between perceived e-shopping value and e-payment comparative perception.

Design/methodology/approach
A questionnaire was distributed, via an online survey, to professional and personal networks of Master students who have spread the survey link to their social media groups. This procedure resulted in 185 valid observations.

Findings
Results show that the comparative perception of e-payment systems, as opposed to cash on delivery, is explained directly by e-payment benefits and indirectly by e-shopping value. The comparison of the model paths based on the perceived compliance to Islamic Sharia showed that this variable is non-significant as a moderator.

Originality/value
The verified model and paths of this study have not been covered yet, namely, the direct and indirect effects of e-shopping value. Thus, their verification constitutes the main originality of this article. Besides, the verification of the moderating role of compliance to Islamic sharia has not been verified in prior studies about e-payment.
Confiscation of proceeds of crime in Vietnam: improving the legal framework
Authors: Tran Thu Thi Hoai , De Koker Louis 
Published: February 2021

Purpose
The purpose of this paper is to analyze the Vietnamese laws and practices concerning the confiscation of proceeds of crime, especially in view of Vietnam’s obligations to meet the international standards on money laundering and terrorist financing, set by the Financial Action Task Force and relevant international conventions that Vietnam ratified. To limit the scope of this paper, the analysis focuses on the confiscation of proceeds of domestic crimes that do not require international legal assistance. This paper concludes with recommendations for improving the legal framework on criminal asset recovery in Vietnam.

Design/methodology/approach
This is a doctrinal study that considers the applicable legal framework. This study is supported by brief case studies of major cases involving the confiscation of proceeds of crime.

Findings
Vietnam has a functioning asset confiscation regime but gaps in the law, lack of financial investigation expertise and lack of focused investigative attention on asset preservation and confiscation are hampering its effectiveness. The key gaps can easily be closed with appropriate amendments to the law. These reforms should be combined with a dedicated skills development program to produce sufficient number of financial investigation experts and criminal asset management experts to support the regime. The training should extend to judicial officers to ensure an appropriate understanding of the asset confiscation law. Reforms such as these should follow on a comprehensive review of Vietnam’s law and practices relating to the confiscation and forfeiture of criminal assets. This review should extend to assets linked to the financing of terrorism and proliferation to ensure that Vietnam has a comprehensive regime to deal with criminal assets.

Research limitations/implications
This paper draws on publicly available information regarding the confiscation of proceeds of crime in Vietnam. Little data is available on asset confiscation and that prevents an in-depth assessment of the regime.

Originality/value
This paper highlights gaps in the current asset confiscation regime and proposes reforms and approaches that will ensure a more effective asset confiscation regime for Vietnam.

Authors: Khan Yasir 
Published: February 2021

PurposeThe nonlinear Schrödinger equation plays a vital role in wave mechanics and nonlinear optics. The purpose of this paper is the fractal paradigm of the nonlinear Schrödinger equation for the calculation of novel solitary solutions through the variational principle.Design/methodology/approachAppropriate traveling wave transform is used to convert a partial differential equation into a dimensionless nonlinear ordinary differential equation that is handled by a semi-inverse variational technique.FindingsThis paper sets out the Schrödinger equation fractal model and its variational principle. The results of the solitary solutions have shown that the proposed approach is very accurate and effective and is almost suitable for use in such problems.Practical implicationsNonlinear Schrödinger equation is an important application of a variety of various situations in nonlinear science and physics, such as photonics, the theory of superfluidity, quantum gravity, quantum mechanics, plasma physics, neutron diffraction, nonlinear optics, fiber-optic communication, capillary fluids, Bose–Einstein condensation, magma transport and open quantum systems.Originality/valueThe variational principle of the Schrödinger equation without the Lagrange multiplier method in the sense of the fractal calculus is developed for the first time in the literature to the best of the author's understanding.

Authors: Maali Kachouri , Rakia Riguen , Khaireddine Mouakhar 
Published: February 2021

PurposeThe purpose of this paper is to investigate the direct and indirect links between corporate governance and sustainability performance using corporate social responsibility.Design/methodology/approachThe study is based on a sample consisting of 300 UK firms over the 2005–2017 period. This study applied structural equations models that specify both a direct and an indirect link between corporate governance and sustainability performance.FindingsThe authors find that corporate governance has a positive effect on sustainability performance. In addition, this study shows that corporate social responsibility fully mediates the relationship between corporate governance and sustainability performance in UK firms.Practical implicationsThis study shows that firms are invited to engage more in sustainability performance and corporate social responsibility activities, which reduces agency conflicts between managers and shareholders.Originality/valueTo the authors’ knowledge, no research studies examined empirically the direct and indirect relationship between corporate governance and sustainability performance. Therefore, the main contribution of this research is to show how corporate governance effectiveness leads to higher corporate social responsibility level and sustainability performance using two analyses methods (mediator analysis and multiple mediator analysis).
Investor protection, corporate governance and private information-based trading
Authors: Lye Chun-Teck , Hooy Chee-Wooi 
Published: February 2021

Purpose
This study aims to examine the effects of investor protection (PROT), internal and external corporate governance (CG) on private information-based trading (PIBT).

Design/methodology/approach
This study uses a sample of 3,438 firms from 42 countries for the period 2002–2015 to examine the effects of the broad and specific measures of PROT, internal CG and external CG (product market competition and block ownership [BOWN]) on a more accurate measure of PIBT using regression analysis.

Findings
The results show that PROT and BOWN are effective in reducing PIBT. However, the specific measure of PROT (strength of PROT) is not significant in emerging markets and civil law countries. The internal CG is also significant but has a positive effect on PIBT.

Research limitations/implications
The results suggest that PROT law matters in the efforts to prevent PIBT. Policymakers and securities market regulators, particularly in emerging markets and civil law countries, should focus more on refining existing securities laws and enacting detailed securities rules that explicitly prevent specific market manipulation and PIBT.

Originality/value
This study provides evidence for the importance of specific and detailed securities rules in different market and legal environments. Furthermore, this study uses the segregated private information-based speculative trading component to accurately measure the PIBT.

Abstract

The effects of nutrient pollution on coral reef ecosystems are multifaceted. Numerous experiments have sought to identify the physiological effects of nutrient enrichment on reef‐building corals, but the results have been variable and sensitive to choices of nutrient quantity, chemical composition and exposure duration.

To test the effects of chronic, ecologically relevant nutrient enrichment on coral growth and photophysiology, we conducted a 5‐week continuous dosing experiment on two Hawaiian coral species, Porites compressa and Pocillopora acuta. We acclimated coral fragments to five nutrient concentrations (0.1–7 µM and 0.06–2.24 µM ) with constant stoichiometry 2.5:1 nitrate to phosphate) bracketing in situ observations from reefs throughout the Pacific.

Nutrient enrichment linearly increased photophysiological performance of both species within 3 weeks. The effect of nutrients on P. acuta photochemical efficiency increased through time while a consistent response in P. compressa indicated acclimation to elevated nutrients within 5 weeks. Endosymbiont densities and total chlorophyll concentrations also increased proportionally with nutrient enrichment in P. acuta, but not in P. compressa, revealing contrasting patterns of host–symbiont acclimatization.

The two species also exhibited contrasting effects of nutrient enrichment on skeletal growth. Calcification was enhanced at low nutrient enrichment (1 µM ) in P. acuta, but comparable to the control at higher concentrations, whereas calcification was reduced in P. compressa (30%–35%) above 3 µM .

Stable isotope analysis revealed species‐specific nitrogen uptake dynamics in the coral–algal symbiosis. The endosymbionts of P. acuta exhibited increased nitrogen uptake (decreased δ15N) and incorporation (19%–31% decrease in C:N ratios) across treatments. In contrast, P. compressa endosymbionts maintained constant δ15N values and low levels of nitrogen incorporation (9%–11% decrease in C:N ratios). The inability of P. acuta to regulate endosymbiont nutrient uptake may indicate an emerging destabilization in the coral–algal symbiosis under nutrient enrichment that could compromise resistance to additional environmental stressors.

Our results highlight species‐specific differences in the coral–algal symbiosis, which influence responses to chronic nutrient enrichment. These findings showcase how symbioses can vary among closely related taxa and underscore the importance of considering how life‐history traits modify species response to environmental change.

Automatic Facial Recognition and the Intensification of Police Surveillance
Authors: Keenan Bernard 
Published: February 2021

AbstractIn R (on the application of Bridges) v Chief Constable of South Wales Police the Court of Appeal held the deployment of live automated facial recognition technology (AFR) by the South Wales Police Force (SWP) unlawful on three grounds. It violated the right to respect for private life under Article 8 of the European Convention on Human Rights because it lacked a suitable basis in law; the Data Protection Impact Assessment carried out under section 64 of the Data Protection Act 2018 was deficient for failing to assess the risks to the rights and freedoms of individuals processed by the system; and SWP failed to fulfil the Public Service Equality Duty imposed by section 149 of the Equality Act 2010 by failing to assess whether or not the software used in the AFR system was biased in relation to sex and race.

Abstract

Ecosystem heterogeneity has been widely recognized as a key ecological indicator of several ecological functions, diversity patterns and change, metapopulation dynamics, population connectivity or gene flow.

In this paper, we present a new R package—rasterdiv—to calculate heterogeneity indices based on remotely sensed data. We also provide an ecological application at the landscape scale and demonstrate its power in revealing potentially hidden heterogeneity patterns.

The rasterdiv package allows calculating multiple indices, robustly rooted in Information Theory, and based on reproducible open‐source algorithms.

AbstractBackgroundCoronavirus disease 2019 (COVID‐19) may be associated with cardiac arrhythmias in hospitalized patients, but data from the ICU setting are limited. We aimed to describe the epidemiology of cardiac arrhythmias in ICU patients with COVID‐19.MethodsWe conducted a multicenter, retrospective cohort study including all ICU patients with an airway sample positive for severe acute respiratory syndrome corona‐virus 2 from March 1st to June 1st in the Capital Region of Denmark (1.8 million inhabitants). We registered cardiac arrhythmias in ICU, potential risk factors, interventions used in ICU and outcomes.ResultsFrom the seven ICUs we included 155 patients with COVID‐19. The incidence of cardiac arrhythmias in the ICU was 57/155 (37%, 95% confidence interval 30‐45), and 39/57 (68%) of these patients had this as new‐onset arrhythmia. Previous history of tachyarrhythmias and higher disease severity at ICU admission were associated with cardiac arrhythmias in the adjusted analysis. Fifty‐four of the 57 (95%) patients had supraventricular origin of the arrhythmia, 39/57 (68%) received at least one intervention against arrhythmia (eg amiodarone, IV fluid or magnesium) and 38/57 (67%) had recurrent episodes of arrhythmia in ICU. Patients with arrhythmias in ICU had higher 60‐day mortality (63%) as compared to those without arrhythmias (39%).ConclusionNew‐onset supraventricular arrhythmias were frequent in ICU patients with COVID‐19 and were related to previous history of tachyarrhythmias and severity of the acute disease. The mortality was high in these patients despite the frequent use of interventions against arrhythmias.

AbstractProblemThe miRNAs show placenta‐specific expression patterns, which alter during pregnancy‐related complications. In present study, the role of miR‐27b‐5p during forskolin‐mediated BeWo cells fusion has been investigated.Method of StudyThe fusion of BeWo cells in response to forskolin treatment (25 µM) was studied by desmoplakin I+II staining. Expression profile of miR‐27b‐5p by qRT‐PCR and its targets HSD3β1 and WNT2B by qRT‐PCR and in Western blot were studied. The effect of overexpression of miR‐27b‐5p and silencing of HSD3β1 & WNT2B by siRNA on forskolin‐mediated BeWo cells fusion and secretion of hCG and progesterone by ELISA was investigated.ResultsTime‐dependent down‐regulation in the expression of miR‐27b‐5p in forskolin‐treated BeWo cells has been confirmed by qRT‐PCR. Overexpression of miR‐27b‐5p significantly inhibits forskolin‐mediated BeWo cells fusion as well as hCG & progesterone secretion. HSD3β1 and WNT2B were identified as targets of miR‐27b‐5p and are up‐regulated in forskolin‐treated BeWo cells. Overexpression of miR‐27b‐5p in BeWo cells downregulates their expression. Further, luciferase reporter assay revealed that miR‐27b‐5p directly target expression of both HSD3β1 and WNT2B. Silencing of both HSD3β1 and WNT2B leads to a significant reduction in forskolin‐mediated BeWo cells fusion with concomitant decrease in the secretion of progesterone or/and hCG. Decrease in forskolin‐mediated cells fusion observed in miR‐27b‐5p mimic transfected BeWo cells could be rescued by the overexpression of both HSD3β1 and WNT2B.ConclusionThese observations suggest that reduced miR‐27b‐5p in forskolin‐treated BeWo cells leads to increased secretion of progesterone and hCG due to loss of repressional control on HSD3β1 and WNT2B.

AbstractObjectivesTo examine patterns and predictors of perceived treatment helpfulness for mania/hypomania and associated depression in the WHO World Mental Health Surveys.MethodsFace‐to‐face interviews with community samples across 15 countries found n = 2,178 who received lifetime mania/hypomania treatment and n = 624 with lifetime mania/hypomania who received lifetime major depression treatment. These respondents were asked whether treatment was ever helpful and, if so, the number of professionals seen before receiving helpful treatment. Patterns and predictors of treatment helpfulness were examined separately for mania/hypomania and depression.Results63.1% (mania/hypomania) and 65.1% (depression) of patients reported ever receiving helpful treatment. However, only 24.5–22.5% were helped by the first professional seen, which means that the others needed to persist in help seeking after initial unhelpful treatments in order to find helpful treatment. Projections find only 22.9% (mania/hypomania) and 43.3% (depression) would persist through a series of unhelpful treatments but that the proportion helped would increase substantially if persistence increased. Few patient‐level significant predictors of helpful treatment emerged and none consistently either across the two components (i.e., provider‐level helpfulness and persistence after earlier unhelpful treatment) or for both mania/hypomania and depression. Although prevalence of treatment was higher in high‐income than low/middle‐income countries, proportional helpfulness among treated cases was nearly identical in the two groups of countries.ConclusionsProbability of patients with mania/hypomania and associated depression obtaining helpful treatment might increase substantially if persistence in help‐seeking increased after initially unhelpful treatments, although this could require seeing numerous additional treatment providers. In addition to investigating reasons for initial treatments not being helpful, messages reinforcing the importance of persistence should be emphasized to patients.
