Since the beginning of coronavirus disease 2019 (COVID-19) pandemic, large attention has been focused on the relationship between SARS-CoV-2 diffusion and environment. As a matter of fact, clear evidence of the transmission of SARS-CoV-2 via respiratory aerosol would be of primary importance; at the same time, checking the presence of SARS-CoV-2 in wastewater can be extremely useful to control the diffusion of the disease. Up to now, many studies report SARS-CoV-2 concentrations in indoor/outdoor air samples or water/wastewater samples that can differ by order of magnitude. Unfortunately, complete information about the scientific approach of many studies is still missing, relating to: samplers and sampling materials performances, recovery tests, measurement uncertainty, robustness, detection and quantification limits, infectivity of captured virus, virus degradation during sampling, influence of sample pre-treatments (included freezing) on results, effects of inhibitors, sample alterations due to manipulation, validation of methods and processes, quality assurance according to ISO/IEC 17025 requirements.Based on the first experiences focused on the presence of SARS-CoV-2 in environmental samples such as air quality filters, air-liquid impingers and wastewater samples, the present study describes a coherent preliminary approach to SARS-CoV-2 environmental sampling in order to overcome the evident lack of standardization. Three aspects are highlighted here: the first solution to assure quality and consistency to environmental sampling relies on the development of recovery tests using standard materials and investigating sampling materials, sampling techniques, sampling durations, sample conservation and pre-treatments; secondly, in order to overcome the shortcomings of every single sampling technique, coupling different samplers in parallel sampling could be an efficient strategy to collect more information and make data more reliable, in particular for air samples; finally, with regards to airborne virus sampling, the results could be confirmed by simplified emission and dilution models.

Executive remuneration has been the subject of close scrutiny, huge public outcries and criticisms in the recent past in South Africa. This has invariably attracted unprecedented research interest across different sectors of the economy. Various studies on executive remuneration versus corporate performance have been conducted across South African companies with no finite consensus. This study joins the debate with the hope of reaching common understanding on the relationship between the two variables. The study seeks to investigate the relationship between CEO remuneration and company performance on the Johannesburg Stock Exchange Listed (JSE) Companies from 2010 to 2015. In particular, the focus of the study was to determine if these two constructs were correlated and aligned with the corporate governance principles. The study, employed a deductive methodological approach, based on a longitudinal, descriptive quantitative design. Purposive sampling technique was used to select the actively listed companies that met the prescribed criteria. Secondary data, sourced from McGregor BFA database was used for the study. Data analysis took an archival quantitative research approach. Regression and time series statistical analyses were performed on secondary data on CEO remuneration and company performance metrics. The findings confirmed the existence of a positive relationship between CEO remuneration and company performance in South Africa as hinted by previous studies

AbstractThe role of environmental transmission of SARS-CoV-2 remains unclear. Particularly the close contact of persons living together or cohabitating in domestic quarantine could result in high risk for exposure to the virus within the households. Therefore, the aim of this study was to investigate the whereabouts of the virus and whether useful precautions to prevent the dissemination can be given.21 households under quarantine conditions were randomly selected for this study. All persons living in each household were recorded in terms of age, sex and time of household quarantine. Throat swabs for analysis were obtained from all adult individuals and most of the children. Air, wastewater samples and surface swabs (commodities) were obtained and analysed by RT- PCR. Positive swabs were cultivated to analyse for viral infectivity.26 of all 43 tested adults (60.47 %) tested positive by RT-PCR. All 15 air samples were PCR- negative. 10 of 66 wastewater samples were positive for SARS-CoV-2 (15.15 %) as well as 4 of 119 object samples (3.36 %). No statistically significant correlation between PCR-positive environmental samples and the extent of infection spread inside the household could be observed. No infectious virus could be isolated under cell culture conditions.As we cannot rule out transmission through surfaces, hygienic behavioural measures are important in the households of SARS-CoV-2 infected individuals to avoid potential transmission through surfaces. The role of the domestic environment, in particular the wastewater load in washbasins and showers, in the transmission of SARS CoV-2 should be further clarified.HighlightsWith public “shut downs” due to SARS-CoV-2, domestic infection is a main possible route of transmission.All analysed air samples were tested negative for SARS-CoV-2.15.15 % of all wastewater samples (washbasin, showers and toilets) were tested positive.Only 3.36 % of all object samples were tested positive: one remote control, two metallic door knobs and one wooden stove overlay.This study supports the hypothesis that indirect environmental transmission may only play a minor role, which needs clarifications in further studies.

Abstract. TV news are essentially cultural phenomena. Previous research suggests that the often-overlooked formal and implicit characteristics of newscasts may be systematically related to culture-specific characteristics. Investigating these characteristics by means of a frame-by-frame content analysis is identified as a particularly promising methodological approach. To examine the relationship between culture and selected formal characteristics of newscasts, we present an explorative study that compares material from the USA, the Arab world, and Germany. Results indicate that there are many significant differences, some of which are in line with expectations derived from cultural specifics. Specifically, we argue that the number of persons presented as well as the context in which they are presented can be interpreted as indicators of Individualism/Collectivism. The conclusions underline the validity of the chosen methodological approach, but also demonstrate the need for more comprehensive and theory-driven category schemes.
