Simulation and analysis of the effects of room surface reflectance combinations on a proposed retrofit illumination system of an office
Authors: Roy Subarna , Majumder Sudipta , Bhattacharya Sourin , Sardar Imran Hossain 
Published: March 2021

Purpose
An indoor office space should not only provide adequate illuminance on horizontal planes but also cater to the physiological and psychological requirements of the occupants. This paper aims to describe a lighting simulation-based work conducted in Kolkata, India which modeled an indoor office to investigate the effects of variation in room surface reflectance combinations on user perception, mean room surface exitance (MRSE), average horizontal illuminance and overall uniformity of horizontal illuminance.

Design/methodology/approach
A fluorescent illumination system–based office space was modeled and retrofitted with tubular LED lamps in DIALux. Simulations were conducted for 16 different room surface reflectance combinations and a five-point Likert scale-type survey questionnaire was formulated to conduct a survey with 32 test subjects to assess the subjective preferability of each resultant light scene.

Findings
Simulation results demonstrate that the relationship between average horizontal illuminance and MRSE as well as between average horizontal illuminance and overall uniformity of horizontal illuminance, was statistically significant (p < 0.001). In the conducted survey, the resultant light scene arising out of the reflectance combination of wall:ceiling:floor = 60%:90%:20% was the most well-received one with 187 convinced agreements (“agree” and “strongly agree” responses).

Originality/value
This work found strong linear correlation between average horizontal illuminance and MRSE and between average horizontal illuminance and overall uniformity. A five-point Likert scale-type survey questionnaire with seven questions was formulated and validated with 32 test subjects (Cronbach’s alpha > 0.9295), which showed that the wall:ceiling:floor reflectance combination of 60%:90%:20% was the most favored choice.

Published: March 2021

PurposeUsing capital asset pricing model (CAPM) and the Z-risk index based on weekly data, this study aims to estimate yearly unsystematic, total, three systematic and insolvency risks in the Gulf Cooperation Council (GCC) countries for the period 2010–2018. The findings of CAPM show positive systematic market risk exposure in all GCC countries for all years, which support the contribution of stock markets to bank prices and returns. The mixed signs of systematic interest rate and exchange rate risks in GCC countries provide hedging opportunities, diversification strategies and regional cooperation, which help risk managers to hedge and stabilize their portfolios against interest rate and exchange rate fluctuations. Therefore, it is necessary that managers and policymakers develop a monitoring system on factors affecting bank insolvency risks to avoid bankruptcies and insolvencies.Design/methodology/approachThis study uses the three-factor CAPM and Z-risk index to measure six types of risks. The CAPM uses market information to estimate the sensitivity of banks to the fluctuations of equity markets, debt markets and foreign exchange markets. Sharpe (1964), Lintner (1965) and Treynor (1965) developed a single-factor CAPM and the coefficient of the model was called systematic market risk. The single-factor CAPM highlights stock markets as the only non-diversifiable source of systematic risks, whereas Stone (1974) and Jorion (1990) highlighted interest rate and exchange rate fluctuations as the other types of non-diversifiable systematic risks. The following functional form in equation (1) estimates five types of risks using CAPM.FindingsThe findings of CAPM show positive systematic market risk exposure in all GCC countries for all years, which support the contribution of stock markets to bank prices and returns based on CAPM theory. The mixed signs of systematic interest rate and exchange rate risks in GCC countries support hedging opportunities and diversification strategies which may help risk managers to hedge and stabilize their portfolios against the fluctuations of interest rate and exchange rate. Although, this policy may decrease the profits of banking sectors but at the same time it would stabilize the portfolios and prevent bankruptcies and big losses because of the fluctuations of interest rate. Moreover, a bank has a better chance to have more liquidity position during financial crises because of the diversifications into different regional markets.Research limitations/implicationsTherefore, this study contributes to the existing literature by using risk measurement by a three-factor CAPM and the Z-risk index as discussed further in methodology.Originality/valueIt is necessary that managers and policymakers develop a monitoring system on factors affecting bank insolvency risks to avoid bankruptcies and insolvencies.

Authors: Higham Lorraine , Girardi Alessandra , Edwards Holly Victoria 
Published: March 2021

Purpose
Autism-specific characteristics have been associated with internet criminal activities. Internet and non-internet offenders differ on a series of demographic, psychological and offending variables. However, the clinical and criminal presentation of individuals with autism spectrum disorder (ASD) in forensic secure care settings has been underexplored. This paper aims to explore the profiles of internet offenders with ASD admitted to a secure psychiatric unit.

Design/methodology/approach
This study provides the results of a service evaluation of individuals with ASD. The demographic, clinical and criminal characteristics of a small sample of internet offenders with ASD admitted to secure care are described and discussed.

Findings
Internet offenders present in secure care with high rates of comorbid disorders, histories of violence and traumatic experiences, mood disorders and difficulties with relationships. Of the 24 internet offenders discussed, 18 of them committed an offence of a sexual nature involving children.

Originality/value
This paper highlights the potential risks for individuals with ASD in using the internet and the possible difficulties associated with detecting this because of rapid advancements in technology.
Impact of process quality management on firm's operational performance: a mediation analysis of firm's absorptive capacity
Authors: Sahoo Saumyaranjan 
Published: March 2021

PurposeThe purpose of this study is to assess the effect of process quality management (PQM) activities on firm's operational performance (OP) through the mediation of firm's absorptive capacity (AC).Design/methodology/approachThis research builds on the theory of knowledge-based view to conduct a survey of 294 manufacturing companies in India. With the use of Hayes' PROCESS Macro in SPSS, the collected data were used to analyze the proposed mediating effect of firm's AC and moderating effects of leadership commitment (LC).FindingsStudy results suggest that both PQM and firm's AC contribute to improved OP and should be promoted. The firm's AC was found to partially mediate the impact of PQM on the firm's OP. Results also show that improved firm's AC can have a substantial effect on improvement in OP by stronger support of LC.Research limitations/implicationsThe results may lack generalizability due to the selected cross-sectional nature of the current study. Researchers are also encouraged to further test the proposed ideas using a longitudinal design approach.Practical implicationsTo translate PQM initiatives into core strategic competencies, manufacturing firms need to develop their AC. Senior managers in the manufacturing sector should concentrate strongly on developing a knowledge-driven working culture to enhance operational efficiency and manufacturing productivity.Originality/valueCurrent research study can be considered as one of the very few empirical analyses that investigated the mediating impact of the firm's AC on the PQM-firm's OP relationship. In the operations management (OM) literature, the investigation of the moderating effect of LC on the mediation of the firm's AC between the PQM and OP metrics can be considered to be a noteworthy theoretical addition.
The interplay among management support and factors influencing organizational learning: an applied study
Authors: Al-Tarawneh Ali Ibrahim , Al-Adaileh Raid 
Published: March 2021

Purpose
This study aims at investigating the impact of some selected organizational and cultural factors on organizational learning (OL). It also attempts to study the moderating role of management support on the influential relationship between these organizational and cultural factors and OL within the context of Jordanian mining sector (JMS).

Design/methodology/approach
A descriptive-analytical approach is applied to collect and analyze the data. A survey questionnaire is used as a primary data collection instrument. The study sample includes 400 participants from the seven selected manufacturing companies within the context of JMS. Smart PLS 3 and IBM SPSS version 25 were applied to answer the study questions and to test the hypotheses.

Findings
Organization strategy has a statistical significant impact on OL. Moreover, cultural factors (innovation; teamwork; knowledge sharing) have a significant impact on OL. The results of the moderating variable revealed that the level of management support is not moderating the relationship between organizational factors and OL. Nonetheless, it is revealed that management support is moderating the relationship between organizational culture and OL.

Practical implications
It seems that a continuous management support is an important facilitating feature to motivate a learning culture. Cultural attributes, including innovation, teamwork and knowledge sharing must be taken into consideration as facilitating factors to encourage OL. Gradual changes must be introduced to create innovative, teamwork and knowledge-sharing culture. Additionally, a specific strategic goal should be part of the organizational corporate strategy and action plans must be developed to achieve this goal in a systematic manner.

Originality/value
The inclusion of management support as a moderating factor could add an original contribution to the current body of knowledge concerning OL. Moreover, this study argues that the core concept of learning might be there but a systematic process of learning and the contextual factors influencing this concept still need more concern.

Gathering data from other populations at different points in time during the COVID-19 pandemic may also be useful.Practical implicationsA review of leadership development programs and organization norms and values is recommended in order to ensure that they are consistent with crisis leadership competencies.Originality/valueThis paper helps address the gap on follower-centered perspectives about organizational leadership responses to crises and highlights the importance of care and compassion in leading employees during difficult times.
An empirical approach to understanding users' fake news identification on social media
Authors: Aoun Barakat Karine , Dabbous Amal , Tarhini Abbas 
Published: March 2021

PurposeDuring the past few years, the rise in social media use for information purposes in the absence of adequate control mechanisms has led to growing concerns about the reliability of the information in circulation and increased the presence of fake news. While this topic has recently gained researchers' attention, very little is known about users' fake news identification behavior. Hence, the purpose of this study is to understand the factors that contribute to individuals' identification of fake news on social media.Design/methodology/approachThis study employs a quantitative approach and proposes a behavioral model that explores the factors influencing users' identification of fake news on social media. It relies on data collected from a sample of 211 social media users which is tested using SEM.FindingsThe findings show that expertise in social media use and verification behavior have a positive impact on fake news identification, while trust in social media as an information channel decreases this identification behavior. Furthermore, results establish the mediating role of social media information trust and verification behavior.Originality/valueThe present study enhances our understanding of social media users' fake news identification by presenting a behavioral model. It is one of the few that focuses on the individual and argues that by identifying the factors that reinforce users' fake news identification behavior on social media, this type of misinformation can be reduced. It offers several theoretical and practical contributions.
Ownership concentration, foreign ownership and auditing: evidence from SMEs in Latin America
Authors: Zhang Dengjun , Cang Yuquan 
Published: March 2021

Purpose
This paper aims to investigate the impact of ownership concentration of the largest shareholder and foreign ownership on the demand for an external audit for small and medium-sized enterprises (SMEs) in six Latin American countries. In particular, the authors test whether foreign-owned firms (compared with domestic private-owned firms) and domestic firms with minority foreign shareholders are more likely engaged in audit assurance.

Design/methodology/approach
The authors applied the logit model to estimate the impact of ownership concentration and owner/shareholder type on audit demand, using a sample of 4,609 SMEs. The probabilities of being audited for firms in these countries are then calculated from the estimation results.

Findings
The empirical results suggest an inverse relationship between ownership concentration and audit demand only for Uruguay and Peru. However, foreign-owned firms and domestic private-owned firms with minority foreign ownership have a high probability of being audited for all sample countries.

Research limitations/implications
Policymakers in developing countries may promote foreign investments in domestic private-owned firms to improve their corporate transparency and governance.

Originality/value
This study contributes to the growing literature on the impact of ownership on audit demand by particularly focusing on foreign owners and foreign minority shareholders. The findings indicate that foreign ownership (either majority or minority) contributes to corporate transparency and business environments in emerging countries.
Transcriptional control of 2,4‐dinitrotoluene degradation in Burkholderia sp. R34 bears a regulatory patch that eases pathway evolution
Authors: Pérez‐Pantoja Danilo , Nikel Pablo I. , Chavarría Max , de Lorenzo Víctor 
Published: March 2021

SummaryThe dnt pathway of Burkholderia sp. R34 is in the midst of an evolutionary journey from its ancestral, natural substrate (naphthalene) towards a new xenobiotic one [2,4‐dinitrotoluene (DNT)]. The gene cluster encoding the leading multicomponent ring dioxygenase (DntA) has activity on the old and the new substrate, but it is induced by neither. Instead, the transcriptional factor encoded by the adjacent gene (dntR) activates expression of the dnt cluster upon addition of salicylate, one degradation intermediate of the ancestral naphthalene route but not any longer a substrate/product of the evolved DntA enzyme. Fluorescence of cells bearing dntA‐gfp fusions revealed that induction of the dnt genes by salicylate was enhanced upon exposure to bona fide DntA substrates, i.e., naphthalene or DNT. Such amplification was dependent on effective dioxygenation of these pathway‐specific head compounds, which thereby fostered expression of the cognate catabolic operon. The phenomenon seems to happen not through direct binding to a cognate transcriptional factor but through the interplay of a non‐specific regulator with a substrate‐specific enzyme. This regulatory scenario may ease transition of complete catabolic operons (i.e. enzymes plus regulatory devices) from one substrate to another without loss of fitness during the evolutionary roadmap between two optimal specificities.

AbstractTo reveal the application potential of microwave heating in the thermal processing of crayfish, this work explored the electromagnetic properties of different parts of crayfish and the patterns of temperature and moisture responses in crayfish during microwave heating. The results of electromagnetic analysis demonstrated that the electromagnetic properties of different parts of crayfish were different, and the tail had higher dielectric properties and reflective loss than other parts, but the maximum thickness of each part of crayfish was almost within their heating depth of microwave. The visual imaging and numerical simulation of temperature and moisture responses showed there were nonuniform temperature and moisture distributions in crayfish during microwave heating. The crayfish tail was selectively heated and rapidly cooked, but its moisture loss was far less than the mass loss of whole crayfish. Furthermore, the immobilized water in crayfish tail meat was continuously converted to free water, while the bound water was relatively stable during microwave heating. This work provided the theoretical references for the assumption that cooking the crayfish by microwave to overcome the shortcomings of boiling.Practical ApplicationIn this work, we innovatively applied microwave heating to the heat processing of crayfish, and analyzed the electromagnetic properties of different parts in crayfish and explored its temperature and moisture responses under microwave field. Although this is a basic research, which provided some theoretical references for the assumption that microwave heating of crayfish (Procambarus clarkia) may be a clean and efficient means of overcoming the shortcomings associated with boiling. In particular, the simulation model of crayfish was established according to its real size and shape, which provided an option for the prediction of temperature response of crayfish in the microwave field.
Development and Validation of the Oral Health Values Scale
Authors: Edwards Cierra B. , Randall Cameron L. , McNeil Daniel W. 
Published: March 2021

AbstractObjectivesOral health values, the degree to which one places importance on or demonstrates investment in improving or maintaining one's dental status, are believed to vary across individuals. Research on this construct is in its infancy, so a new Oral Health Values Scale (OHVS) was developed and validated. The aim was to create a multidimensional measure of oral health values that could be used in future epidemiological or behavioural investigations involving determinants of dental treatment‐seeking behaviour and/or oral health.MethodsThe OHVS was developed in three cross‐sectional phases. A 45‐item pool was developed, and 12 expert raters from various oral health professions rated the items for their representativeness and relevance, as well as specificity and clarity. Based on the expert feedback, an initial 30‐item scale was subsequently established and administered to a developmental sample (N = 306) using Amazon's Mechanical Turk (MTurk). The scale was further refined to be 12 items and its structure was confirmed in a validation sample (N = 308), also using MTurk. Correlations among OHVS scores and other oral health‐related constructs were examined in the developmental and validation samples.ResultsExpert review of items for the oral health values construct and the OHVS provided initial evidence of content validity. The final 12‐item scale exhibited a four‐factor structure with good internal consistency, α = 0.84. The psychometric properties of the final scale were confirmed in a second sample using confirmatory factor analysis, although evidence for the OHVS's four‐factor structure was mixed. Overall, OHVS scores were consistently related to other oral health constructs in anticipated ways, providing evidence of construct validity.ConclusionsThe OHVS demonstrated content validity, internal consistency, and construct validity. Results suggest that the OHVS is a psychometrically sound instrument.

Published: March 2021

SummaryThe American Academy of Paediatrics recommends that primary care paediatricians “prescribe” follow‐up for weight management between well child checks. We sought to describe rates and predictors of prescribed and actual clinic attendance for weight management in primary care in a predominantly low‐income population. A chart review was performed at a large, hospital‐based, primary care clinic, where a treatment algorithm for obesity exists. Eligible children were 6 to 12 years of age with a body mass index (BMI) ≥85th percentile and seen for a well child check in 2014. Primary outcomes were the physician prescribing follow‐up in primary care and the patient returning for weight management. Multivariable logistic regression was used to identify predictors of prescribing follow‐up and predictors of return. Participants included 1339 patients: mean age 9 years (SD: 1.8 years); 53% female; 79% Black; 89% Medicaid‐insured; 56% with an obese BMI (vs overweight). Twenty‐seven percent of patients were prescribed follow‐up in primary care, of which 13% returned (only 4% of the original sample). The odds of the physician prescribing follow‐up were greater if the child had obesity (vs overweight), was older, female or non‐Medicaid insured. Older and non‐Black patients had greater odds of returning. Patients prescribed follow‐up within 2 months or less (vs 3‐6 months) were also more likely to return (aOR 2.66; CI: 1.34, 5.26). Rates of prescription for weight management in primary care are low and few patients return, even when follow‐up is prescribed. Prescribing follow‐up at shorter intervals from the index visit (≤ 2 months) may improve patient return.
