More harm than good? Cannabis, harm and the misuse of drugs act
Authors: Potter Gary R. , Wells Hattie 
Published: November 2021

Purpose
This paper aims to consider the nature of cannabis-related harms under the UK’s Misuse of Drugs Act (MDA). Written for the specific context of this four-paper special section on 50 years of the MDA, it argues that the MDA may cause more harm than it prevents.

Design/methodology/approach
An opinion piece offering a structured overview of cannabis-related harms under prohibition. It summarises existing evidence of the ways in which prohibition may exacerbate existing – and create new – harms related to the production, distribution, use and control of cannabis.

Findings
The paper argues that prohibition of cannabis under the MDA may cause more harm than it prevents.

Originality/value
It has long been argued that the MDA does not accurately or fairly reflect the harms of the substances it prohibits, and much existing research points to different ways in which drug prohibition can itself be harmful. The originality of this paper lies in bringing together these arguments and developing a framework for analysing the contribution of prohibition to drug-related harm.
Radical innovation, incremental innovation, and competitive advantage, the moderating role of technological intensity: evidence from the manufacturing sector in Jordan
Authors: Al-Khatib Ayman Wael , Al-ghanem Eyad Mustafa 
Published: November 2021

Purpose
The purpose of this paper is to identify the effect of radical innovation and incremental innovation on the competitive advantage of Jordanian industrial companies and identify the moderating role of technological intensity.

Design/methodology/approach
For this study’s purposes, 303 questionnaires from employees of 30 manufacturing firms were analysed. Convergent validity and discriminant validity tests were performed through structural equation modelling in the Smart-PLS programme. Data reliability was confirmed. A bootstrapping technique was used to analyse the data. Multi-group analysis was performed to investigate the moderating role of technological intensity.

Findings
Empirical results showed that both radical innovation and incremental innovation explain 60.2% of the variance in competitive advantage and that both constructs have a statistically significant effect on competitive advantage. The results also revealed that the relationship between radical innovation and competitive advantage is modified through the high-tech industries. Meanwhile, the relationship between incremental innovation and competitive advantage is modified through the low-tech industries.

Research limitations/implications
This cross-sectional study provides a snapshot at a given moment in time, a methodological limitation that affects the generalization of its results and the results are limited to one country, Jordan.

Practical implications
This study promotes the idea of focusing on radical and incremental innovation to enhance competitive advantage in the Jordanian manufacturing sector and knowing the effect of technological intensity in this relationship.

Originality/value
This study has important implications for leaders in the Jordanian manufacturing sector in general, as the study highlights the importance of radical innovation and incremental innovation to enhance the competitive advantage, especially in light of the technological intensity in this sector, and thus, increase the innovative capabilities of this firms, which leads to an increase in the level of competitive advantage.
Development and validation of the professional sense of competence scale (ProSOCS) for practitioners who treat disruptive behaviours in children
Authors: Swan Kellie , Shanley Dianne C. , Zimmer-Gembeck Melanie J. 
Published: November 2021

PurposeThe purpose of this paper is to develop a measure of practitioner sense of competence when treating children with disruptive behaviours.Design/methodology/approachTwo online surveys were conducted with health, social work and psychology practitioners (n = 113 and n = 239, respectively) working within varied Australian clinical settings. Study 1 developed scale items and conducted an exploratory factor analysis of the initial Professional Sense of Competence Scale (ProSOCS). Study 2 conducted confirmatory factor analysis and tested the construct validity of the scale.FindingsStudy 1 established a three-factor model, which accounted for 56.9% of variance in the ProSOCS items. Study 2 confirmed the three-factor model and considered an alternative unidimensional model. Study 2 demonstrated good convergent validity with measures of knowledge and general sense of competence.Originality/valueThe ProSOCS is a valid and reliable way to measure three subscales of a more global composite score of practitioner sense of competence when treating children with disruptive behaviours. Disruptive behaviour represents one of the most common reasons for child presentation in mental health care settings. Understanding how sense of competence among professionals who treat disruptive behaviours in children relates to their level of training, treatment decisions and outcomes could help to enhance use of evidence-based treatment strategies and complement strategies for measuring competence-based training in post-graduate settings.
Corporate value creation, stock price synchronicity and firm value in China: implications for beyond
Authors: Zhang Ruopiao , Chu Teresa , Noronha Carlos , Guan Jieqi 
Published: November 2021

PurposeThis study introduces Social Contribution Value per Share (SCVPS), an indicator devised by the Shanghai Stock Exchange (SSE), as an easy-to-interpret Measurement of Corporate Social Performance (MCSP) to the international research arena. The authors first explore the informativeness role of voluntary disclosure of SCVPS in the stock market. The authors then go one step further to demonstrate the relationship between corporate value creation quantified by SCVPS and firm value.Design/methodology/approachThe study takes a new perspective – a quasi-natural experiment of SCVPS disclosure in 2008 and uses a Propensity Score Matched Difference in Difference model (PSM-DiD) to investigate the impact of SCVPS disclosure policy on stock price synchronization and firm value. Through manually recalculating all the values of SCVPS and its components, this study enables us to further investigate the relationship between corporate value creation for various stakeholders and firm value.FindingsThis study reveals that voluntary disclosure of SCVPS can signal firm-specific information to the market and reduce noise in returns, thus affecting stock price synchronization. The findings further demonstrate that such firm-specific information has value relevance to firm performance. Moreover, the authors demonstrate that corporate value creation for different stakeholders measured by SCVPS can significantly affect firm value. The moderating effects of ownership structures and industry types are also investigated, and an endogeneity test confirms the robustness of the findings.Practical implicationsThis study argues that SCVPS offers an economically viable way for firms, including small-and-medium-sized enterprises, in emerging economies to disclose corporate value creation and provide the public with a direct understanding and appreciation of the values created by corporations for stakeholders.Originality/valueThe result makes contributions to the MCSP literature and explores the informativeness of SCVPS disclosure. Besides, this paper demonstrates that SCVPS offers a good setting to explore the effect of corporate value creation on firm performance in an emerging market.
An analytical and probabilistic model with concordance for detecting mine-like objects with mirror symmetry
Authors: Nguyen Phuc Bao Uyen 
Published: November 2021

PurposeThe purpose is to develop search and detection strategies that maximize the probability of detection of mine-like objects.Design/methodology/approachThe author have developed a methodology that incorporates variational calculus, number theory and algebra to derive a globally optimal strategy that maximizes the expected probability of detection.FindingsThe author found a set of look angles that globally maximize the probability of detection for a general class of mirror symmetric targets.Research limitations/implicationsThe optimal strategies only maximize the probability of detection and not the probability of identification.Practical implicationsIn the context of a search and detection operation, there is only a limited time to find the target before life is lost; hence, improving the chance of detection will in real terms be translated into the difference between success or failure, life or death. This rich field of study can be applied to mine countermeasure operations to make sure that the areas of operations are free of mines so that naval operations can be conducted safely.Originality/valueThere are two novel elements in this paper. First, the author determine the set of globally optimal look angles that maximize the probability of detection. Second, the author introduce the phenomenon of concordance between sensor images.
Value-at-risk predictive performance: a comparison between the CaViaR and GARCH models for the MILA and ASEAN-5 stock markets
Authors: Serrano Bautista Ramona , Núñez Mora José Antonio 
Published: November 2021

PurposeThis paper tests the accuracies of the models that predict the Value-at-Risk (VaR) for the Market Integrated Latin America (MILA) and Association of Southeast Asian Nations (ASEAN) emerging stock markets during crisis periods.Design/methodology/approachMany VaR estimation models have been presented in the literature. In this paper, the VaR is estimated using the Generalized Autoregressive Conditional Heteroskedasticity, EGARCH and GJR-GARCH models under normal, skewed-normal, Student-t and skewed-Student-t distributional assumptions and compared with the predictive performance of the Conditional Autoregressive Value-at-Risk (CaViaR) considering the four alternative specifications proposed by Engle and Manganelli (2004).FindingsThe results support the robustness of the CaViaR model in out-sample VaR forecasting for the MILA and ASEAN-5 emerging stock markets in crisis periods. This evidence is based on the results of the backtesting approach that analyzed the predictive performance of the models according to their accuracy.Originality/valueAn important issue in market risk is the inaccurate estimation of risk since different VaR models lead to different risk measures, which means that there is not yet an accepted method for all situations and markets. In particular, quantifying and forecasting the risk for the MILA and ASEAN-5 stock markets is crucial for evaluating global market risk since the MILA is the biggest stock exchange in Latin America and the ASEAN region accounted for 11% of the total global foreign direct investment inflows in 2014. Furthermore, according to the Asian Development Bank, this region is projected to average 7% annual growth by 2025.

Authors: Khalifa Mohamed A. , Aziz Mohamed A. , Hamza Mohamed , Abdo Saber , Gaheen Osama A. 
Published: November 2021

PurposeFire door should withstand a high temperature without deforming. In the current paper, the challenges of improving the behaviour of the conventional fire door were described using various internal stiffeners in pair swinging-type fire door.Design/methodology/approachThe temperature distribution on the outside door surface was measured with distributed eight thermocouples. Subsequently the internal side was cooled with pressurized water hose jet stream of 4 bar. The transient simulation for the thermal and structure analysis was conducted using finite element modelling (FEM) with ANSYS 19. The selected cross sections during numerical simulation were double S, double C and hat omega stiffeners applied to 2.2 m and 3 m door length.FindingsDuring the FEM analysis, the maximum deformations were 7.2028, 5.4299, 5.023 cm for double S, double C and hat omega stiffeners for 2.2 m door length and 6.57, 4.26, 2.1094 cm for double S, double C and hat omega stiffeners for 3 m door length. Finally, hat omega gives more than three times reduction in the deformation of door compared to double S stiffeners which provided a reference data to the manufacturers.Research limitations/implicationsThe research limitation included the limited number of fire door tests due to the high cost of single test, and the research implication was to achieve an optimal study in fire door design.Practical implicationsAchieving the optimum design for the internal door stiffeners where the hat omega stiffener gives minimum door deformation compared to the other stiffeners was considered the practical implication. The work included two experimental fire door tests according to the standard fire test (ANSI/UL 10C – Positive Pressure of Fire Tests of Door Assemblies) for a door of 2.2 m length with double S stiffeners and a door of 3 m length with hat omega stiffeners, which achieved minimum deformation.Originality/valueThe behavior and mechanical response of door leaf were improved through using internal hat omega stiffeners under fire testing. This study was achieved using FEM in ANSYS 19 for six cases of different lengths and stiffeners for fire doors. The simulation model showed a very close agreement with the experimental results with an error of 0.651% for double S and 1.888% for hat omega.

Published: November 2021

Purpose
Life conditions for most slum dwellers are deplorable, with poor socio-economic status and high rates of malnutrition and communicable diseases. Studies have shown lower intake of many nutrients in such people, but no study yet has checked the quality of diet using Healthy Eating Index (HEI) in them. This study aims to assess the quality of diet among slum dwellers of Tehran using the HEI-2015.

Design/methodology/approach
This cross-sectional study was conducted among 300 slum dwellers from two slums located on the border of Tehran city which is the capital of Iran. Stratified random sampling technique was used to select subjects for this study. Data on socioeconomic characteristics and 24-hours dietary recalls were obtained through face-to-face interviews with the respondents by trained personnel.

Findings
The overall diet quality of the respondents was poor, with a mean HEI score of 40.9 ± 23.7. About 84% of the participants had low overall HEI scores. A significant relation was seen in the following: the HEI and educational level (p = 0.044); the HEI and employment status (p = 0.001); and the HEI and chronic diseases (p = 0.049). There was no significant difference between the mean HEI score and marital status, welfare status and addiction status. From the findings, the diet of most of these slum dwellers needs modification. Therefore, taking measures to reduce slum dwelling and to improve the nutritional intake of this study population is needed.

Originality/value
The study was approved by the Ethics Committee of Tehran University of Medical Sciences, Tehran, Iran, and written informed consent was obtained from all participants.

Authors: Koronios Konstantinos , Ntasis Lazaros , Dimitropoulos Panagiotis , Ratten Vanessa 
Published: November 2021

PurposeThe scope of this study was to underline the specific aspects of positive consumer attitude and behavior related to sports sponsorship. In more detail, the purpose of this study was to establish a comprehensive sponsorship framework integrating Beliefs about sponsorship, Sponsor's Image, Fans' Attachment with the team, Team's Performance, Fans' Sport Involvement, Sponsors' Sincerity, Awareness of Sponsors, Attitude toward Sponsors, Purchase intentions and Actual Purchases.Design/methodology/approachQuantitative method was utilized and a sum of 2,752 questionnaires were effectively assembled and analyzed by means of SPSS and AMOS. The results of a structural equation model provide an exceptional conceptual framework that underlines the significance of comprehending the role of important factors in sponsorship efficiency.FindingsThis paper provides the context for a discussion. It shows that various antecedents have a significant effect on real – instead of just intentions – purchase behavior regarding sponsors' products and services.Research limitations/implicationsVarious implications for future researches as well as strategies to boost the advantages for both sport clubs and sponsoring firms can be drawn from the suggested model.Originality/valueUp to present, only a handful of empirical studies have looked at the effect of sponsorship on the consumer. The majority of sponsorship studies measure the impact of the sponsorship effort on the recall and recognition of sponsors, with empirical results being inconclusive, with some studies showing high levels of recall and recognition while others show only marginal impact on recall and recognition. The present research provides a comprehensive framework, which can guide future studies by isolating the effect of sponsorship on actual purchase behavior, instead of just estimating individuals' purchase intentions.
Data protection, information governance and the potential erosion of ethnographic methods in health care?
Authors: Lee Rebecca R. , McDonagh Janet E. , Farre Albert , Peters Sarah , Cordingley Lis , Rapley Tim 
Published: November 2021

AbstractWith the most recent developments to the European General Data Protection Regulations (GDPR) introduced in May 2018, the resulting legislation meant a new set of considerations for study approvers and health‐care researchers. Compared with previous legislation in the UK (The Data Protection Act, 1998), it introduced more extensive and directive principles, requiring anybody ‘processing’ personal data to specifically define how this data will be obtained, stored, used and destroyed. Importantly, it also emphasised the principle of accountability, which meant that data controllers and processors could no longer just state that they planned to adhere to lawful data protection principles, they also had to demonstrate compliance. New questions and concerns around accountability now appear to have increased levels of scrutiny in all areas of information governance (IG), especially with regards to processing confidential patient information. This article explores our experiences of gaining required ethical and regulatory approvals for an ethnographic study in a UK health‐care setting, the implications that the common law duty of confidentiality had for this research, and the ways in which IG challenges were overcome. The purpose of this article was to equip researchers embarking on similar projects to be able to navigate the potentially problematic and complex journey to approval.
Cisd2 slows down liver aging and attenuates age‐related metabolic dysfunction in male mice

Published: November 2021

AbstractThe liver plays a pivotal role in mammalian aging. However, the mechanisms underlying liver aging remain unclear. Cisd2 is a pro‐longevity gene in mice. Cisd2 mediates lifespan and healthspan via regulation of calcium homeostasis and mitochondrial functioning. Intriguingly, the protein level of Cisd2 is significantly decreased by about 50% in the livers of old male mice. This down‐regulation of Cisd2 may result in the aging liver exhibiting non‐alcoholic fatty liver disease (NAFLD) phenotype. Here, we use Cisd2 transgenic mice to investigate whether maintaining Cisd2 protein at a persistently high level is able to slow down liver aging. Our study identifies four major discoveries. Firstly, that Cisd2 expression attenuates age‐related dysregulation of lipid metabolism and other pathological abnormalities. Secondly, revealed by RNA sequencing analysis, the livers of old male mice undergo extensive transcriptomic alterations, and these are associated with steatosis, hepatitis, fibrosis, and xenobiotic detoxification. Intriguingly, a youthful transcriptomic profile, like that of young 3‐month‐old mice, was found in old Cisd2 transgenic male mice at 26 months old. Thirdly, Cisd2 suppresses the age‐associated dysregulation of various transcription regulators (Nrf2, IL‐6, and Hnf4a), which keeps the transcriptional network in a normal pattern. Finally, a high level of Cisd2 protein protects the liver from oxidative stress, and this is associated with a reduction in mitochondrial DNA deletions. These findings demonstrate that Cisd2 is a promising target for the development of therapeutic agents that, by bringing about an effective enhancement of Cisd2 expression, will slow down liver aging.

Published: November 2021

AbstractThis study evaluated the perceived vibration, noise and discomfort levels associated with two nickel‐titanium file systems with different kinetics; reciprocating motion (REC) using WaveOne Gold and continuous rotation motion (CON) using ProTaper NEXT. Forty roots with two canals from maxillary premolar and molar of 40 patients were included. Root canals were instrumented using each system for each canal. Patients were surveyed about the vibration, noise and discomfort experienced using visual analogue scale, and their preference. The responses were statistically analysed using Wilcoxon Signed‐Rank test, Mann–Whitney U test and Spearman’s rank correlation test at the 95% of significance level. The vibration, noise and discomfort experienced were significantly greater in REC than CON (P < 0.05). In REC, male subjects reported significantly higher vibration than female (P < 0.05). Majority respondents (72.5%) preferred the CON method. The perceived vibration, noise and discomfort were less apparent from the CON than the REC.
Novel non‐steroidal mineralocorticoid receptor antagonists in cardiorenal disease
Authors: Kintscher Ulrich , Bakris George L. , Kolkhof Peter 
Published: November 2021

Mineralocorticoid receptor antagonists (MRAs) are key agents in guideline‐oriented drug therapy for cardiovascular diseases such as chronic heart failure with reduced ejection fraction and resistant hypertension. Currently available steroidal MRAs are efficacious in reducing morbidity and mortality; however, they can be associated with intolerable side effects including hyperkalaemia in everyday clinical practice. Recently, a new class of non‐steroidal MRAs (including esaxerenone, AZD9977, apararenone, KBP‐5074 and finerenone) have been developed with an improved benefit–risk profile and a novel indication for finerenone for diabetic kidney disease. To better understand the non‐steroidal MRAs, this review provides information on the molecular pharmacology as well as relevant current preclinical and clinical data on cardiorenal outcomes. A comparative review of all compounds in the class is discussed with regard to clinical efficacy and safety as well as a perspective outlining their future use in clinical practice.LINKED ARTICLESThis article is part of a themed issue on Emerging Fields for Therapeutic Targeting of the Aldosterone‐Mineralocorticoid Receptor Signaling Pathway.
