  • Objectives: The purpose of this study is to identify the causes of the retardation of administrative relief under the Special Act on Remedy for Damages Caused by Humidifier Disinfectant and to suggest the systematic refurbishment of this act for the quick and fair of relief of damages. Methods: This study was conducted through the application of the case study, literature review and systematic interpretation of law methods. Results: The disease subject to administrative relief under the Special Act is defined as health damage causally associated to a substantial degree with exposure to humidifier disinfectant. This definition is a strict requirement in light of the legislative purpose of prompt and fair relief of damages. Furthermore, the damage relief committee established under the Special Act judged causal relationships according to a rigorous standard in terms of medical certainty. This medical evidence-based judgment is a result of the committee's failure to understand the normative meaning and function of a causal relationship as an outcome of inference based on empirical rules and common sense. Conclusions: Humidifier disinfectant health damage should be defined as a health-related injury capable of occurring or deteriorating after exposure to humidifier disinfectant (HD). If the fact that a particular injury occurred or worsened after exposure to HD was found, then the damage can be presumed as being caused by HD. However, this might not be the case when the injury was considered to have occurred or been exacerbated entirely due to other factors.

  • Purpose - This study empirically investigates whether the risk property included in fat-tails of return distributions is systematic or unsystematic based on the devised statistical methods. Design/methodology/approach - This study devised empirical designs based on two traditional methods: principal component analysis (PCA) and the testing method of portfolio diversification effect. The fatness of the tails in return distributions is quantitatively measured by statistical probability. Findings - According to the results, the risk property in the fat-tails of return distributions has the economic meanings of eigenvalues having a value greater than 1 through PCA, and also systematic risk that cannot be removed through portfolio diversification. In other words, the fat-tails of return distributions have the properties of the common factors, which may explain the changes of stock returns. Meanwhile, the fatness of the tails in the portfolio return distributions shows the asymmetric relationship of common factors on the tails of return distributions. The negative tail in the portfolio return distribution has a much closer relation with the property of common factors, compared to the positive tail. Research implications or Originality - This empirical evidence may complement the existing studies related to tail risk which is utilized in pricing models as a common factor.

  • The increased risk in financial firms, due to Global Financial Crises and high international trade activities, has encouraged banks to use derivatives for both managing their financial risk and earning non-operating income simultaneously. The present study brings new evidence in the existing literature by determining the drivers behind financial derivative usage in Pakistani banks for 2011 till 2016. Moreover, the paper examines how risk plays a moderating role in determining the relationship between derivative usage and bank value. While assessing the determinants, a two-stage test has conducted, first, the logit regression was used to test the drivers behind the derivative usage in banks. Second, Tobit regression was run to analyze the factors leading to determine the extent of derivative usage. The findings demonstrate that Pakistani banks are using derivatives for both risk management and speculative motive as they are customers and users of derivatives at the same time. Empirical results, regarding moderating role of risk on the value implications of derivative usage, provide mixed findings as derivative usage gives value premium in case of non-systematic risk and foreign exchange risk. Whereas value discounts have been observed for cases where systematic risk is high and managers try to earn non-operating income from speculative activities.

  • Software development organizations are globalizing their development activities increasingly due to strategic and economic gains. Global software development (GSD) is an intricate concept, and various challenges are associated with it, specifically related to the software requirement change management Process (RCM). This research aims to identify humans' related success factors (HSFs) and human-related challenges (HCHs) that could influence the RCM process in GSD organizations and propose a theoretical framework of the identified factors concerning RCM process implementation. The Systematic Literature Review (SLR) method was adopted to investigate the HSFs and HCHs. Using the SLR approach, a total of 10 SFs and 10 CHs were identified. The study also reported the critical success factors (HCSFs) and critical challenges (HCCHs) for RCM process implementation following the factors having a frequency 50% as critical. Our results reveal that five out of ten HSFs and 4 out of ten HCHs are critical for RCM process implementation in GSD. Finally, we have developed a theoretical framework based on the identified factors that indicated a relationship among the identified factors and the implementation of the RCM process in the context of GSD. We believe that the results of this research can help tackle the complications associated with the RCM in GSD environment, which is vigorous to the success and progression of GSD organizations.

  • Purpose: The underdog effect refers to a positive attitude towards the underdog who lacks resources and opportunities but has passion and determination. Extensive research has been investigated how the underdog effect affects distributing consumer preference and purchase intention. The purpose of this study is to identify the theoretical basis on which the underdog effect is grounded by analysing the prior research in the underdog literature. Research design, data and methodology: This study organizes the literature on the underdog effect by analyzing a total of 33 journals published in the past 16 years. Constructs and variables were extracted from the selected articles through the content analysis on a systematic literature review. Results: This literature review reveals that identity theories served as an overarching theoretical lens when examining the underdog effect. Additionally, the underdog effect was rooted in theories of justice and equity to explain the relationship between underdog brand positioning and consumer preference. Conclusions: This paper paves the way for future research based on prior research and trend analysis of underdog brand positioning. This article also provides an insightful interpretation and synthesis of the theoretical underpinnings of the impact of underdog effects on consumers' overall brand evaluations.

  • Purpose: Leisure time is an intrinsic part of the work-life balance that enables people to rejuvenate their energy and provides a platform to maintain their health while sustaining their productivity levels. The purpose of this study is to investigate the effects of changes in leisure consumption culture on the modern economy through various research materials. Research design, data and methodology: To have completeness in published systematic reviews and meta-analyses, the use of the standard Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist is essential and the present research selected this research design. Results: This research figured out that individuals who spend most of their leisure time watching TV have been shown to experience lesser satisfaction in their job designation and less happiness overall and also found that Leukocyte Telomere Length is influenced by the type of leisure an individual engages in. Conclusions: Overall, this research points out that the income effect may provide an inverse relationship between work time and labor in that high income from labor makes an individual less inclined to work to make the same money they made before the increased benefits. It is a narrative that may need further research in finding the principles that govern leisure in the labor force.

  • Purpose: To prove the credibility of EBD, it is necessary to define concepts regarding the nature of credible knowledge and the hierarchy of evidence. In addition, the relationship between EBD and EBP needs to be addressed through a practical viewpoint. Methods: The systematic review is applied to define the nature of knowledge and the characteristics of research papers in architectural EBD while analyzing the field of study, knowledge focus and types of keywords of the first author. Results: As a whole, the types of research focus evaluated using the most frequent keywords include function(40.86%), specialized knowledge(30.52%), professional practice(21.37%), and health(5.78%). Empirical research(83.72%) is more likely to be found than theoretical research(13.95%). The EBD research papers ranked as top-tier are only 7(2.03%) among a total of 344, while the research papers ranked in the third to fourth tiers are 276(80.23%). Implications: There is a deficiency of reliable 1-2 tier research papers. From a practical viewpoint, it would be realistic to recommend that healthcare architects appropriately evaluate the quality of EBD research and apply it in practice, rather than to conduct EBD research themselves. This systematic review illustrates the nature of EBD research.

  • Purpose: The purpose of this study was to determine the effect of agricultural exports and imports on economic growth in Bangladesh and propose an upgraded and customized model of the supply chain for agribusiness growth in Bangladesh to achieve plain sailing and systematic operation and financial gains at home and abroad. Research design, data, and methodology: All data in the research have been collected from secondary sources. Gross domestic product was used as the dependent variable and exports and imports of agricultural products were used as independent variables. Pairwise Granger causality was utilized to see the impact of the variable responsible for the economic growth in Bangladesh and the causal relationship between the variables analyzed was measured using Johansen co-integration test. Results: From the empirical analysis, the researchers observed that agricultural commodity imports and exports have a unidirectional impact on economic growth in Bangladesh and a long-run causal link with economic growth in Bangladesh. The suggested supply chain model of agribusiness aids in achieving smooth operations, systematic management, and monetary gains both domestically and internationally. Conclusions: This paper contributes to the development of a more effective and profitable agribusiness supply chain in Bangladesh systematically through their theoretical and practical implications.

  • Purpose: The study aims to synthesize research trends regarding the distribution of 'other customer perception' on 'brand experience'; concurrently, to identify the promising research directions and suggest useful for managers. Research design, data, and methodology: The paper deals with the distribution of 'other customer perception' on 'brand experience' through evaluating a systematic review combined with biological mapping analysis (VOS viewer) with 226 documents published in 142 journals from 1987 to 2021. Results: The study synthesizes and analyzes existing literature reviews on the distribution of 'other customer perception' on 'brand experience', which mainly highlights three research topic groups. Exploring the component of relationship should be considered in the brand experience scale when the research context is the social interactions surrounding the customer's purchasing process. Moreover, the presence of mindfulness in several publications has suggested a potential research direction in the consumer behavior field. Conclusions: The systematic reports can be a useful reference for managers towards building brand experience based on distribution of 'other customer perception' with moderating of mindfulness - a new finding of behavioral interaction that has just experienced the Covid-19 pandemic which is experienced directly at the store and lead to many changes in consumer psychology.

  • Objectives: This study investigated the relationship between suicidal behavior and the use of methylphenidate (MPH) or atomoxetine (ATX) in patients with attention deficit hyperactivity disorder (ADHD). Methods: The Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines were used to conduct a meta-analysis. The Physiotherapy Evidence Database scale was used to score the quality of the studies. Results: Nine studies were included in this quantitative analysis. The analysis included 602864 patients with ADHD (521125 and 81739 patients were taking methylphenidate [MPH group] and atomoxetine [ATX group], respectively) and 19230 healthy controls. The overall estimates were in the order of the control, MPH, and ATX groups; however, no statistically significant between-group difference was observed in the incidence of events (p=0.553 for control vs. MPH; p=1.000 for control vs. ATX; p=1.000 for MPH vs. ATX). Conclusion: The rate of suicidal behavior was higher in the ADHD groups treated with MPH and ATX than in the control group. However, no statistically significant difference was observed between the ADHD groups treated with MPH and ATX, and the control group. Therefore, MPH and ATX did not increase suicidal behavior.
