A multi-objective opposition-based barnacles mating optimization for image super resolution using hyper-Spectral images
Authors: Bhasha A. Valli , Reddy B.D. Venkatramana 
Published: August 2021

Purpose
The problems of Super resolution are broadly discussed in diverse fields. Rather than the progression toward the super resolution models for real-time images, operating hyperspectral images still remains a challenging problem.

Design/methodology/approach
This paper aims to develop the enhanced image super-resolution model using “optimized Non-negative Structured Sparse Representation (NSSR), Adaptive Discrete Wavelet Transform (ADWT), and Optimized Deep Convolutional Neural Network”. Once after converting the HR images into LR images, the NSSR images are generated by the optimized NSSR. Then the ADWT is used for generating the subbands of both NSSR and HRSB images. The residual image with this information is obtained by the optimized Deep CNN. All the improvements on the algorithms are done by the Opposition-based Barnacles Mating Optimization (O-BMO), with the objective of attaining the multi-objective function concerning the “Peak Signal-to-Noise Ratio (PSNR), and Structural similarity (SSIM) index”. Extensive analysis on benchmark hyperspectral image datasets shows that the proposed model achieves superior performance over typical other existing super-resolution models.

Findings
From the analysis, the overall analysis of the suggested and the conventional super resolution models relies that the PSNR of the improved O-BMO-(NSSR+DWT+CNN) was 38.8% better than bicubic, 11% better than NSSR, 16.7% better than DWT+CNN, 1.3% better than NSSR+DWT+CNN, and 0.5% better than NSSR+FF-SHO-(DWT+CNN). Hence, it has been confirmed that the developed O-BMO-(NSSR+DWT+CNN) is performing well in converting LR images to HR images.

Originality/value
This paper adopts a latest optimization algorithm called O-BMO with optimized Non-negative Structured Sparse Representation (NSSR), Adaptive Discrete Wavelet Transform (ADWT) and Optimized Deep Convolutional Neural Network for developing the enhanced image super-resolution model. This is the first work that uses O-BMO-based Deep CNN for image super-resolution model enhancement.
Factors affecting BIM implementation in post-conflict low-income economies: the case of Afghanistan
Authors: Al-Mohammad Mohammad S. , Haron Ahmad Tarmizi , Aloko Mohammad Numan , Rahman Rahimi A. 
Published: August 2021

Purpose
Rejecting building information modeling (BIM) can negatively impact the architectural, engineering and construction (AEC) industries. While BIM is trending globally, its implementation in post-conflict low-income economies is still limited. The purpose of this paper is to identify the critical factors for implementing BIM in a post-conflict low-income economy, using Afghanistan as a case study.

Design/methodology/approach
This study identifies potential affecting factors for BIM implementation through reviewing existing literature and interviewing AEC professionals in Afghanistan. Then, the factors are inserted into a questionnaire survey and disseminated with Afghanistan’s AEC practitioners. The collected data was analyzed to determine the critical factors. Also, the underlying relationships between the critical factors were established through factor analysis.

Findings
A total of 11 critical factors are affecting BIM implementation in Afghanistan. From those, nine factors can be grouped into the following three components: technological, environmental and organizational. Two factors, “cost-benefit of implementing BIM” and “market demand for BIM,” are recurring in low- and middle-income economies. Conversely, the “presence of appropriate projects to implement BIM” is the unique critical factor for Afghanistan that might affect other post-conflict low-income economies.

Originality/value
This study focuses on affecting factors for BIM implementation in post-conflict low-income economies, using Afghanistan as a reference rather than other types of economies that have been widely studied.

An embezzler test for norms, standards and regulations
Authors: Cardao-Pito Tiago 
Published: August 2021

Purpose
The purpose of this study is to address the question that economic standards, norms and regulations can possess weak spots that might be exploitable for the embezzlement of an organization’s assets with resultant material consequences in money laundering,tax evasion, fraud, corruption and other potential financial crimes.

Design/methodology/approach
The author’s methodological approach is to introduce and discuss a new logical-deductive test that the author names “embezzler test”. The author’s test investigates regulatory architectures from the perspective of someone attempting to divert assets from or to an organization. It appraises whether a potential embezzler could divert resources without being detected and sanctioned.

Findings
The embezzler test can be applied to a broad range of standards, norms and regulations.

Research limitations/implications
This new test can be improved and further calibrated in future research.

Practical implications
Researchers, regulators and law makers can use the new test to identify and eventually fix weak spots for embezzlement in norms, standards and regulations.

Originality/value
To the best of the author’s knowledge, such a test has never been formulated or applied before to identify weak spots for potential embezzlement in regulatory architectures.
Investigating the role of regulatory focus in apparel attribute prioritization
Authors: Hyun Jonghan 
Published: August 2021

PurposeThe purpose of this study is to utilize consumers' regulatory focus as a segmentation variable to understand how and why consumers shift their tendency to prioritize certain apparel attributes.Design/methodology/approachSix hypotheses are developed and then tested via two experiments. Self-administered online questionnaire is used to collect data from a total of 1,178 participants recruited via Amazon Mechanical Turk. The collected data is analyzed using series of Chi-square tests and ANOVAs.FindingsResults show that promotion-focused (prevention-focused)) consumers are not only more likely to prioritize apparel attributes that ensure the attainment of satisfaction (avoidance of dissatisfaction) but also attach higher monetary value to apparel products bearing such attributes.Originality/valuePrevious studies of apparel attribute prioritization utilized static segmentation variables such as age or gender despite the dynamic nature of attribute prioritization tendency. This study extends the literature by demonstrating the significance of consumers' regulatory focus – a dynamic segmentation variable that has not been studied in the current context.

Published: August 2021

Purpose
The purpose of this paper is to provide a systematic and comprehensive review of the existing literature on the determinants of firms reporting practices.

Design/methodology/approach
Following a systematic method, the sample literature of 135 studies was collected from the Scopus database. These studies were evaluated in terms of the theoretical lenses applied in the literature, yearly trend, regional distribution, research settings and prior studies finding to provide some recommendations for further research.

Findings
The investigation revealed that the literature was more interested in the agency theory in investigating the drivers of voluntary reporting such as company size, age, leverage, liquidity, profitability, corporate governance and ownership structure. Although firm-specific determinants were the most examined in the previous studies, however, the result is still inconclusive. Also, limited work was found on the country-related factors, while internal audit impact has yet to be explored.

Originality/value
Being the first of its kind, this research provides a comprehensive review of the current research landscape on the drivers of environmental or social disclosure and highlights several interesting opportunities for future research.

Service employees’ workplace fun and turnover intention: the influence of psychological capital and work engagement
Authors: Tetteh Stephen , Dei Mensah Rebecca , Opata Christian Narh , Mensah Claudia Nyarko 
Published: August 2021

Purpose
As a way of addressing how best turnover intention among service employees can be reduced through workplace fun, this study aims to examine how psychological capital (PsyCap) and work engagement, respectively, moderates and mediates the relationship between workplace fun and turnover intention in a moderated mediation.

Design/methodology/approach
Using cross-sectional quantitative design, data were collected by means of questionnaires and convenience sampling. The hypotheses were tested with 482 service employees from the hospitality industry in Ghana using PROCESS macro.

Findings
The findings depict that work engagement mediates the relationship between workplace fun and turnover intention among service employees. Also, PsyCap moderates the workplace fun–engagement relationship, in addition to the workplace fun–work engagement–turnover intention relationship. Specifically, both relationships are stronger for employees with high PsyCap.

Practical implications
The authors would like to conclude that as frontline employees are usually subjected to stressful conditions, monotonous working environments and emotional labor, which affect the quitting intention, incorporating fun into the workplace will strategically help frontline employees to be engaged in their work and reduce their intentions to quit.

Originality/value
With a focus on a developing economy, this work is novel in exploring possible factors that may help increase work engagement and reduce turnover intention among service employees.

Published: August 2021

PurposeThe purpose of this study is to examine the perceptions of Malaysian and Bangladeshi retail small- and medium-sized enterprise (SME) business owners on the key elements of business growth.Design/methodology/approachThe construct measurements have all been taken from previous research studies. The data were gathered from retail SMEs in Malaysia and Bangladesh in order to evaluate entrepreneurs' perception towards the essential elements of a business performance. Structural equation modeling (SEM) with PLS technique, specifically Smart-PLS Version 3.2.4, was used to accomplish the study's objectives and analyze the measurements, as well as the structural model.FindingsAccording to the findings, Malaysian and Bangladeshi SMEs have different perspectives toward the dimensions of their business performance. For example, Malaysian retail SME owners consider business growth and financial results to be the most important aspects of their success. Retailers consider financial performance to be less critical than non-financial performance when it comes to their business's success. Owners of Bangladeshi retail SMEs, on the other hand, see efficiency relative to competition and that non-financial performance is the key component to achieving business success. In the sense of Bangladeshi SMEs, market development and financial results are seen as less significant in attaining success.Research limitations/implicationsSince this research was only conducted in Malaysia and Bangladesh, it did not cover a large number of countries. The sample size was limited; therefore, the findings of this study cannot be applied to the entire population of Malaysian and Bangladeshi retail SMEs due to the non-probability sampling technique.Practical implicationsThe findings of this study show that entrepreneurs or business owners in the retail sector in Malaysian and Bangladeshi SMEs view the attributes of their business performance differently.Originality/valueThis study adds to the rising context of entrepreneurship by examining SME owners' perception of main business performance dimensions in the scope of Asian retail SMEs.

AbstractLow‐grade fibromyxoid sarcoma (LGFMS) is a rare sarcoma subtype that most commonly arises in young adults. This tumor typically presents in the deep soft tissues of the proximal extremities or trunk as a painless mass. Although the most common site of LGFMS metastasis is the lung, it is rarely the primary site. Here, we report a case of primary pulmonary LGFMS. A 22‐year‐old asymptomatic man was referred to our hospital for investigation of a lung mass that had been discovered incidentally. Computed tomography (CT) showed a well‐defined mass 4.0 cm in diameter in the upper lobe of the right lung. Malignancy was suggested by focal uptake of 18F‐fluorodeoxyglucose positron‐emission tomography (18‐FDG‐PET). Following surgery, postoperative histological analysis of the resected specimen demonstrated LGFMS based on histological and immunohistological findings. In particular, mucin 4 showed diffuse positivity in the spindle‐shaped tumor cells. In conclusion, LGFMS can arise in the lungs, and physicians should consider this entity as a differential diagnosis for solitary lung mass in young adults.
Evaluating the impact of preferential trade agreement on fishery imports: An application of difference‐in‐differences with matching method
Authors: Chi Pei‐Yu , Chang Ting‐Yu , Chang Kuo‐I 
Published: August 2021

AbstractThe purpose of thisstudy is to investigate the average treatment effect of the preferential tariff scheme at the HS 6‐digit level on the imports of fishery products between each OECD country and the world. The estimated results by employing a difference‐in‐differences with matching method show statistically positive average treatment effects for imports of frozen yellowfin tuna (HS030342) and fresh long‐finned tuna (HS030231) in many countries. However, there are also several negative average treatment effects on imports, implying that several OECD countries do not utilize preferential tariff schemes with exporter countries with sufficient productivity. This study fills the gap in the literature by providing more rigorous insights in the discussion regarding the trade creation/diversion effect of preferential trade agreements (PTAs).
Increased uterine NLRP3 inflammasome and leucocyte infiltration in a rat model of preeclampsia

Published: August 2021

AbstractThe disruption of the inflammatory microenvironment in the uterus affects pregnancy outcome. However, the exact quantification and distribution of leukocyte subpopulations in the uterus in preeclampsia (PE) have not been clearly characterized. Inflammasomes promote the release of proinflammatory cytokines interleukin (IL)‐β and IL‐18. A higher expression of NLRP3 inflammasome in placentas contributes to excessive inflammation in PE. However, related studies on the uterus are scarce. We aimed to investigate changes in the infiltration of leukocyte subpopulations in decidual and uterine tissues, and explore the role of activation of uterine NLRP3 inflammasomes in PE. Decidual tissues were collected from normotensive pregnant women and preeclamptic women. A PE‐like model was established via administration of lipopolysaccharide to normal pregnant rats. Uterine and decidual tissues were collected from all experimental groups. It was found that the number of leukocytes was significantly elevated in decidual and uterine tissues in PE patients compared to normal controls. The leukocytes (predominantly macrophages and NK cells) particularly infiltrated into the decidua and uterine decidua in PE‐like rats, and these were sparse in the myometrium. The NLRP3 immunoreactivity in the uterus was extremely little in control rats, its immunoreactivity and caspase‐1 immunoreactivity were significantly elevated in the PE‐like rats; the mRNA expression results also indicated an upward trend in the activation of NLRP3 inflammasomes. These results support that leucocyte infiltration in the decidua and uterine deciduas, and the activation of NLRP3 inflammasome in the uterus, which participate in the pathogenesis, are responsible for the excessive inflammation at the maternal‐fetal interface during PE.

AbstractThis study investigated the effects of intrauterine growth restriction during late pregnancy on the ovine fetal renal function and renal antioxidant capacity. Eighteen ewes pregnant were randomly divided into control group (CG, ad libitum, 0.67 MJ ME·BW−0.75·day−1, n = 6), restricted group 1 (RG1, 0.18 MJ ME·BW−0.75·day−1, n = 6), and restricted group 2 (RG2, 0.33 MJ ME·BW−0.75·day−1, n = 6). At 140 days, the fetal blood, allantoic fluid and kidney tissue were collected to determinate fetal renal function and renal antioxidant capacity. The results showed that the fetal weight, kidney weight, superoxide dismutase (SOD), glutathione peroxidase (GSH‐Px), aquaporin‐2 (AQP‐2) and aquaporin‐3 (AQP‐3), and total antioxidant capacity (T‐AOC) in RG1 group were decreased compared with the CG (P < 0.05), but the contents of β2‐Microglobulin (β 2‐MG), cystatin C (Cys‐C), filtered sodium excretion fraction (FENa), malondialdehyde (MDA), and hydroxyl radical (OH) in RG1 group were increased (P < 0.05). The impaired ovine fetal renal growth, antioxidant imbalance and dysfunction of glomerulus ultrafiltration, and the renal tubules reabsorption were induced by maternal malnutrition during late pregnancy.

Published: August 2021

AbstractMitosis is a prognostic factor for cutaneous melanoma (CM), but accurate mitosis detection in CM tissues is difficult. Therefore, the 8th Edition of the American Joint Committee on Cancer staging system has removed the mitotic rate as a category criterion of the tumor T‐category, based on the evidence that the mitotic rate was not an independent prognostic factor for melanoma survival. As single‐nucleotide polymorphisms (SNPs) have been shown to be potential predictors for cutaneous melanoma‐specific survival (CMSS), we investigated the potential prognostic value of SNPs in mitosis‐related pathway genes in CMSS by analyzing their associations with outcomes of 850 CM patients from The University of Texas MD Anderson Cancer Center in a discovery dataset and validated the findings in another dataset of 409 CM patients from the Harvard University Nurses’ Health Study and Health Professionals Follow‐up Study. In both datasets, we identified two SNPs (SDCCAG8 rs10803138 G>A and MAGI2 rs3807694 C>T) as independent prognostic factors for CMSS, with adjusted allelic hazards ratios of 1.49 (95% confidence interval = 1.17‐1.90, P = .001) and 1.45 (1.13‐1.86, P = .003), respectively. Furthermore, their combined unfavorable alleles also predicted a poor survival in both discovery and validation datasets in a dose‐response manner (Ptrend = .0006 and .0001, respectively). Additional functional analysis revealed that both SDCCAG8 rs10803138 A and MAGI2 rs3807694 T alleles were associated with elevated mRNA expression levels in normal tissues. Therefore, these findings suggest that SDCCAG8 rs10803138 G>A and MAGI2 rs3807694 C>T are independent prognostic biomarkers for CMSS, possibly by regulating the mRNA expression of the corresponding genes involved in mitosis.
