A new coronavirus denominated first 2019-nCoV and later SARS-CoV-2 was found in Wuhan, China in December of 2019. This paper compares three mathematical methods: nonlinear regression, SIR, and SEIR epidemic models, to track the covid-19 disease in nine countries affected by the SARS-CoV-2 virus, to help epidemiologists to know the disease trajectory, considering initial data in the pandemic, mainly 100 days from the beginning. To evaluate the results obtained with the three methods one-way ANOVA is applied. The average of predicted infected cases with SARS-CoV-2, obtained with the mentioned methods was: for United States of America 1,098,508, followed by Spain with 226,721, Italy with 202,953, France with 183,897 United Kingdom with 182,190, Germany with 159,407, Canada with 58,696, Mexico with 50,366 and Argentina with 4,860 in average. The one-way ANOVA does not show a significant difference among the results of the projected infected cases by SARS-CoV-2, using nonlinear regression, SIR, and SEIR epidemic methods. The above could mean that initially any method can be used to model the pandemic course.

Abstract Section 162 of the South African Companies Act 71 of 2008 empowers courts to declare directors delinquent and hence to disqualify them from office. This article compares the judicial disqualification of directors under this section with the equivalent provisions in the United Kingdom, Australia and the United States of America, which have all influenced the South African act. The article compares the classes of persons who have locus standi to apply to court to disqualify a director from holding office, as well as the grounds for the judicial disqualification of a director, the duration of the disqualification, the application of a prescription period and the discretion conferred on courts to disqualify directors from office. It contends that, in empowering courts to disqualify directors from holding office, section 162 of the South African Companies Act goes too far in certain respects.

The Impact

This study explores the impact of environmental policies and human development on the CO2 emissions for the period of 1995–2015 in the Group of Seven and BRICS economies in the long run through panel cointegration and causality tests. The causality analysis revealed a bilateral causality between environmental stringency policies and CO2 emissions for Germany, Japan, the United Kingdom, and the United States of America, and a unilateral causality from CO2 emissions to the environmental stringency policies for Canada, China, and France. On the other hand, the analysis showed a bilateral causality between human development and CO2 emissions for Germany, Japan, the United Kingdom, and the United States of America, and unilateral causality from CO2 emissions to human development in Brazil, Canada, China, and France. Furthermore, the cointegration analysis indicated that both environmental stringency policies and human development had a decreasing impact on the CO2 emissions.

The Arts

Study Objective. Suicide is a serious health problem that is shaped by a variety of social and mental health factors. A growing body of research connects the arts to positive health outcomes; however, no previous systematic reviews have examined the use of the arts in suicide prevention and survivorship. This review examined how the arts have been used to address suicide prevention and survivorship in nonclinical settings in Australia, Canada, the United Kingdom, and the United States of America. Design and Setting. Ten bibliographic databases, five research repositories, and reference sections of articles were searched to identify published studies. Articles presenting outcomes of interventions conducted between 2014 and 2019 and written in English, were included. Primary Results. Nine studies met inclusion criteria, including qualitative, quantitative randomized controlled trials, quantitative nonrandomized, quantitative descriptive, and mixed-methods studies. The programs studied used film and television (n = 3), mixed-arts (n = 3), theatre (n = 2), and quilting (n = 1). All nine interventions used the arts to elicit emotional involvement, while seven also used the arts to encourage engagement with themes of health. Study outcomes included increased self-efficacy, awareness of mental health issues, and likelihood for taking action to prevent suicide, as well as decreases in suicidal risk and self-harming behaviors. Conclusions. Factors that influence suicide risk and survivorship may be effectively addressed through arts-based interventions. While the current evidence is promising with regard to the potential for arts programs to positively affect suicide prevention and survivorship, this evidence needs to be supplemented to inform recommendations for evidence-based arts interventions.

Family Of Distributions

We construct a model for the progress of the 2020 coronavirus epidemic in the United States of America, using probabilistic methods rather than the traditional compartmental model. We employ the generalized beta family of distributions, including those supported on bounded intervals and those supported on semi-infinite intervals. We compare the best-fit distributions for daily new cases and daily new deaths in America to the corresponding distributions for United Kingdom, Spain, and Italy. We explore how such a model might be justified theoretically in comparison to the apparently more natural compartmental model. We compare forecasts based on these models to observations, and find the forecasts useful in predicting total pandemic deaths.

AbstractThe workshop brought together some twenty persons from varied and diverse nations and political-economic circumstances - Ghana, Netherlands, New Zealand, Republic of South Africa, United Kingdom, United States of America, West Germany and Zimbabwe. The workshop also reflected a number of Christian denominations - Anglican, Lutheran, Presbyterian, Reformed, Roman Catholic and Seventh Day Adventist. The gathering then was truly pluralistic and ecumenical. Such composition made for a rich encounter of varied and diverse understandings and approaches.
