AbstractAnthropogenic factors have significantly influenced the frequency, duration, and intensity of meteorological drought in many regions of the globe, and the increased frequency of wildfires is among the most visible consequences of human-induced climate change. Despite the fire role in determining biodiversity outcomes in different ecosystems, wildfires can cause negative impacts on wildlife. We conducted ground surveys along line transects to estimate the first-order impact of the 2020 wildfires on vertebrates in the Pantanal wetland, Brazil. We adopted the distance sampling technique to estimate the densities and the number of dead vertebrates in the 39,030 square kilometers affected by fire. Our estimates indicate that at least 16.952 million vertebrates were killed immediately by the fires in the Pantanal, demonstrating the impact of such an event in wet savanna ecosystems. The Pantanal case also reminds us that the cumulative impact of widespread burning would be catastrophic, as fire recurrence may lead to the impoverishment of ecosystems and the disruption of their functioning. To overcome this unsustainable scenario, it is necessary to establish proper biomass fuel management to avoid cumulative impacts caused by fire over biodiversity and ecosystem services.

Using English to teach and learn academic subjects in higher education (HE) across the globe is increasing in popularity. The overarching aim of this study is to examine the impact of English-medium instruction (EMI) on Omani engineering students’ academic performance and their studies in an English-medium engineering programme in Oman. This paper reports on findings from a larger project that was intended to investigate Omani engineering students’ experience of learning through the medium of English in one of the Colleges of Technology in Oman. The study adopted a qualitative interpretative approach with a case study strategy and a purposive sampling technique to look into the impact of EMI on Omani engineering students’ academic performance and their studies. The sample included 12 Omani engineering and 8 engineering instructors who were interviewed along with five classroom observations. The data were collected and generated through semi-structured interviews and classroom observations. They were analysed manually, inductively and thematically using Braun and Clarke’s model (2006). The findings showed that EMI had both positive and negative impacts on the students’ academic performance and their studies.

Many ecological variants have impact on the onset and communicability of infectious diseases or pandemics, which may in later days can trigger environmental feedback. The most potentially lethal virus of this century coronavirus disease (COVID-19) was declared an epidemic on March 13, 2020, and its vigorous spread, congruous coverage and its many diverse and complicated after effects may have made it a very dangerous disease to counteract the problems related to it in such a short time period making it once in only century disaster around the world. Most of the countries around the world being currently in a situation of chaos and suffering of this disease and its consequences have responded with great concern and measures by taking social distancing methods and measures of various kinds and drastically reducing the spread of the virus and helping in prevention by it have also helped in resolving many economic and other activities of the country to cope with. As a result, the COVID-19 pandemic at the end of April 2020 caused many environmental impacts, including positive impacts such as improved air quality. Negative impacts such as coastal pollution through the elimination of water and sanitation supplies in urban areas and in rural have shown it effects of healing the surrounding which was caused by the halting to many industries and the release of waste products and hampering of the transport and its emission after the public went into home isolation after the pandemic started. This study provides a first overview of the observed environmental and possible aftermath of COVID-19. We argue that the impact of COVID-19 is largely determined by anthropogenic factors that become apparent as public events declines around the globe, and effects on towns and human health will continue to exist.

The main objective of this study is to examine the impact of socio-cultural and organizational factors affecting the career development of female employees. With judgmental/ purposive sampling technique, only 142 respondents have been selected out of 150 questionnaires distributed to female school teachers. This study has tested reliability of questionnaires by using Cronbach alpha. Using multiple regression analysis, it has been found that both socio-cultural and organizational factors have negative impact on women career development. Hence, a conclusion can be drawn-out of the study that there are negative impacts of socio-cultural and organizational factors on women career development. Considering the outcomes, it can be claimed that the study could be useful for school management, trainers, and human resource developers to assist the career development of female school teachers.

Introduction: Disaster management is a dynamic, continual, and integrated process as to increase the qualities of the actions which are relevant to the process of observation and analysis of disaster as well as minimalizing the negative impacts, mitigation, readiness, early warning, immediate emergency, rehabilitation and reconstruction. The aim of this research is to analyse theconnection between disaster management and the prevention of community breakdown in order to face a volcanic eruption for every head of household. Method: The design of this research is correlational research with a cross sectional approach. The demographic group that is used for this research is the head of households in Rt 06/Rw 01 dusun Puncu desa Puncu, by using the purposive sampling technique which has been collected from the sampling of the 33 heads of households. Independent variable is the knowledge of disaster management, and the dependent variable is the prevention of community breakdown in the handling of the disaster. The data has been received by using the questionnaire, and the results have been analysed by using spearman rho test. Result:  As according to the statistics test, it is found that p-value= 0,000 on the significant level (α) = 0,05 and r = 0,752. It is concluded that there is a connection between knowledge and the prevention of community breakdown in handling of the volcanic eruption in Rt 06/Rw 01. This research shows that the level of knowledge within the community about disaster management and prevention in handling volcanic eruption has been increasing. Conclution: This is shown by the capability of the community in mitigating the effects of the disaster. It is hoped that the community will further engage in training education and simulation to reduce the negative impacts of a disaster. The location where the participants resideis Kelud Volcano, and it is therefore hoped that the communities are willing to participate in better handling of any disaster by joining the education training and simulation; Kata kunci : Pengetahuan, Manajemen bencana, Prevention.
