COVID-19-Related Suicides in Bangladesh Due to Lockdown and Economic Factors: Case Study Evidence from Media Reports.

Abstract: The incidence and mortality of the coronavirus-2019 disease (COVID-19) have increased dramatically around the world. The effects of COVID-19 pandemic are not limited to health, but also have a major impact on the social and economic aspects. Meanwhile, developing and less developed countries are arguably experiencing more severe crises than developed countries, with many small and medium-sized businesses being disrupted and even bankrupt (Fernandes 2020). Consequently, some individuals’ mental health is very fragile (Lin 2020). Sahoo et al. (2020) reported some of the psychological consequences in India (the neighboring country of Bangladesh) including self-harm due to COVID-19 misinformation. Moreover, impacts on mental health (e.g., depression, anxiety, panic, and traumatic stress) can also occur due to the lack of accurate information (Rajkumar 2020; Sahoo et al. 2020; Tandon 2020). In addition, pandemic-related restraints (e.g., spatial distancing, isolation, home quarantine, etc.) is impacting on economic sustainability and well-being, which may induce psychological mediators, such as sadness, worry, fear, anger, annoyance, frustration, guilt, helplessness, loneliness, and nervousness (Mukhtar 2020; Mamun and Griffiths 2020a). These mediators are also distinctive features of psychological suffering that individuals can experience during and after pandemics (Ahorsu et al. 2020; Pakpour and Griffiths 2020). Without early economic interventions, such mental health issues can facilitate suicidal behaviors among some individuals (Arafat and Mamun 2019; Mamun and Griffiths 2020b, c; Jahan et al. 2020), because economic recession, unemployment, and poverty are strongly associated with severe psychological comorbidities such as suicidal behaviors (Goldman-Mellor et al. 2010; Oyesanya et al. 2015; Rafi et al. 2019). There is one prior study that has examined COVID-19-related suicide in Bangladesh (Mamun and Griffiths 2020a).

Exercise Addiction: Symptoms, Diagnosis, Epidemiology, and Etiology

Abstract: Regular physical activity plays a crucial role in health maintenance and disease prevention. However, excessive exercise has the potential to have adverse effects on both physical and mental health. The scholastic and empirical discussion of excessive physical activity focuses on obsessive and compulsive exercising, and uses several labels. However, in this review, we argue that the most appropriate term for this phenomenon is exercise addiction, emphasizing that excessive physical exercise fits the typical and most common characteristics of behavioral addictions. The aim of this review is to synthesize the current knowledge on symptomology, diagnosis, epidemiology, and etiology of exercise addiction.

The effect of audit committee characteristics on intellectual capital disclosure

Abstract: This paper, using data from 100 UK listed firms, investigates the relationship between audit committee characteristics and intellectual capital (IC) disclosure. We find that overall IC disclosure is positively associated with audit committee characteristics such as the size and frequency of meetings, and negatively associated with audit committee directors' shareholding. We find no significant relationship between IC disclosure and audit committee independence and financial expertise. We also observe that the association between audit committee characteristics and IC disclosure varies with the IC components (i.e. human capital, structural capital and relational capital), suggesting that the underlying factors that drive various components of IC disclosure are different. These results have important implications for policy-makers in that they confirm that the effectiveness of audit committees in the corporate reporting processes is a function of certain characteristics.

Using IT in the undergraduate classroom: should we replace the blackboard with PowerPoint

Abstract: Three studies were performed to investigate the efficacy of digital PowerPoint lecturing in undergraduate classrooms. In the first study, students’ opinion about PowerPoint lectures was surveyed after receiving all their lectures in one module in PowerPoint. Grades of one cohort were then compared with the grades of another taking the same test one year earlier. No significant differences were found. In another study, students received a mock test 1 week following: (1) an overhead lecture, (2) a PowerPoint lecture and (3) a PowerPoint lecture with lecture notes. There were no significant differences between the two PowerPoint lectures both of which resulted in higher grades than the overhead lecture. In the third study, two cohorts had two identical lectures, in a counterbalanced order, presented either with PowerPoint or by using overheads. The results revealed that the lecture difficulty, but not the method of lecturing, contributed to the grade differences on two mock tests. It is suggested that the efficacy of PowerPoint lecturing may be case specific rather than universal.

Multiple Time Series

Abstract: In medical investigations, it is not uncommon to record observations on two or more time series For example, blood pressure and weight may be regularly monitored on a sample of patients The individual time series may be analyzed by methods appropriate for univariate series, but this article concentrates on methods of analysis that help in understanding the system that gives rise to the data Keywords: time series; fast Fourier transformation; autoregressive moving average; vector models
