The life cycle of mines lasts from several years to several decades. The closure of the mine occurs when its recourses are completely extracted, or mining is no longer profitable within its leasehold. Most regulatory authorities all around the world require the plan of mines and open-pits closure even before the mining begins, as it must be determined that the site would not pose a threat to the environment or society in future. Depending on the location, the site of mine or open-pit may be used in alternative way after closure or restored to the pre-operational condition. Local authorities increasingly require financial assurance that the funds needed to close mining enterprises will also be available in emergency situations. Special attention is paid to the environmental insurance intended to limit liability related to pollution elimination after mining activities at abandoned fields are over. In close connection with environmental insurance is post-mining – the development of alternative use of mining sites after the closure of mines and open-pits.

Illegal open-pit mining causes environmental harm and undermines sustainable development. Conventional monitoring approaches such as field research and unmanned aerial vehicle (UAV) imagery are time-consuming and labor-intensive, making large-scale monitoring difficult. In comparison, optical remote sensing imagery can cover large areas but is vulnerable to adverse weather conditions and is not sensitive to vertical ground changes. As open-pit excavation causes sudden changes in the scattering properties of ground objects along with dramatic vertical deformation, we evaluated the feasibility of using interferometric synthetic aperture radar (InSAR) coherence to identify illegal mining activities. Our method extracts the coherence coefficient from two SAR images taken on different dates, applies thresholding and filtering to extract a decorrelation map, and then overlays this with legal mining boundaries and optical satellite images to identify illegal mining activities. For three test cases in southwestern Inner Mongolia, China, 49 legal mining sites were correctly detected (with an accuracy of 90.74%) as well as six illegal mining sites. Ground truthing confirmed the presence of ongoing activity at one of these sites. Our study shows that InSAR coherence is suitable for the identification of mining activities, and our method provides a new approach for the detection and monitoring of illegal open-pit mining.

The development of the mining industry is necessary for the national GDP growth. The gold mining operation provides great support to local people in the construction of roads, hospitals and schools. However the damage caused due to the illegal gold mining in Ivory Coast has become increasingly worrying. Thousands of miners unlawfully exploit gold in many parts of the national territory. The local people, especially the children see artisanal gold mining as a faster way to get out of the growing poverty. According to the investigation with local people, MDA, mining companies, the rebellion in 2002 and the post-election crisis in 2010 were a key issue. As result of the political unrest many children have left school to move into the mining activities. This paper focuses on some existing problems relating to the minors in artisanal gold mine as well as how the illegal gold mining activities should increasingly concern the state’s authorities who have to display their determination to stop this recurring phenomenon. In this paper, some suggestions will be proposed and we also support some initiatives and actions of the current government in order to reduce the rate of children or if possible to withdraw all the children from mining sites. The World Bank, financial institutions, NGOs are appealing too to play a major support role to eradicate child labor and to protect children in Ivory Coast and over the world.

Dust generation sources come from mining sites including mine dumps, crushing, hauling, grinding and offloading of waste material from open pit and underground operation and non-operations, movement of trucks on unpaved roads, etc. Many mine dumps in South Africa are not rehabilitated due to the possibility of re-mining in the case of asbestos dumps or have been abandoned by previous owners for different reasons. Some of the reasons for abandonment include bankruptcy, ineffective enforcement, lack of financial assurance, minimal penalties for non-compliance and commodities like gold, asbestos and coal are affected. Historically, only long asbestos fibres were used for manufacturing purpose. While short fibres were unwanted

Central Purpose

This book, comprised of 13 chapters, presents papers which discuss the processes related to the career along one’s life cycle, from adolescents’ professional choices until processes of retirement. Notwithstanding the diversity of life and work contexts, present in the different chapters, they all somewhat correspond in their central purpose, presenting both perspectives and challenges related to contemporary career interventions. Some chapters address themes that are still seldom explored in national literature, while others discuss subjects that are long established in the area, however they are innovative. The authors study them in the context of changes in the world of work in the second decade of the 21st century, of the new career models and psychosocial processes that are linked to human development throughout life. The studies and practices in vocational guidance, career development and retirement, included in this book, are the results of research and practice in recent years carried out by professionals, professors and academics that in different ways have collaborated with the activities of LIOP - Laboratory of Information and Professional Guidance, at the Federal University of Santa Catarina.

The socio-environmental challenges the world faces are ‘swamps’: situations that are messy, complex, and uncertain. The aim of this paper is to help disciplinary scientists navigate these swamps. To achieve this, the paper evaluates an integrative framework designed for researching complex real-world problems, the Integration and Implementation Science (i2S) framework. As a pilot study, we examine seven inter and transdisciplinary agri-environmental case studies against the concepts presented in the i2S framework, and we hypothesise that considering concepts in the i2S framework during the planning and delivery of agri-environmental research will increase the usefulness of the research for next users. We found that for the types of complex, real-world research done in the case studies, increasing attention to the i2S dimensions correlated with increased usefulness for the end users. We conclude that using the i2S framework could provide handrails for researchers, to help them navigate the swamps when engaging with the complexity of socio-environmental problems.

Growing environmental problems and increasing requirements of green jobs force universities around the world not only to transform their curricula but also to enrich existing ones with contents related to the promotion of sustainable development. This paper aims to show the importance of measuring and monitoring the share of green contents in all university activities, as only in that way it is possible to monitor trends and give realistic assessments of their effect and importance. The paper presents a comparative analysis of different types of methodologies for assessing sustainable activities at universities as well as research conducted at the University of Novi Sad in Serbia and its comparison with the University of Gothenburg (Sweden). This research aims to point out the importance of increasing competitiveness in higher education through assessment of green content in a curriculum and its promotion. In this way, through eco-labeling methodology, it would be easier to identify those contents that, in a certain share, contribute to the promotion of sustainable development. Furthermore, this methodology can easily be extended across the country and the region, which would bring positive effects to all stakeholders in higher education.

Abstract The world is facing a global pandemic of COVID-19 caused by the SARS-CoV-2 coronavirus. Here we describe a collection of codon-optimized coding sequences for SARS-CoV-2 cloned into Gateway-compatible entry vectors, which enable rapid transfer into a variety of expression and tagging vectors. The collection is freely available. We hope that widespread availability of this SARS-CoV-2 resource will enable many subsequent molecular studies to better understand the viral life cycle and how to block it.

Abstract. Regime change in Eastern Europe affords an excellent opportunity for investigating linkages between age and politics in times of social turmoil. Using data from three waves of the World Values Survey, this paper explores life cycle, generational and period effects on protest potential in Yeltsin's Russia. The study finds that an individual's position in the life cycle is the strongest predictor of protest potential in the post-communist state. Furthermore, the analysis suggests that citizens socialized during periods of relative socioeconomic stability exhibit the highest protest potential under conditions of uncertainty characteristic of the transition period.Résumé. Les changements de régime en Europe de l'Est permettent d'examiner la relation complexe entre l'âge et la politique pendant les périodes d'instabilité sociale. S'appuyant sur les données de trois vagues du World Values Survey (sondage mondial sur les valeurs), cet article explore l'incidence du cycle de vie, de la génération et de la période sur le potentiel protestataire dans la Russie d'Eltsine. L'étude démontre que la position de l'individu dans le cycle de vie est le plus puissant facteur de prédiction du potentiel protestataire dans la société postcommuniste. En outre, les citoyens socialisés pendant des périodes de relative stabilité socio-économique présentent le potentiel protestataire le plus élevé dans des conditions d'incertitude caractéristiques de la période de transition.
