This work is the first part of a national review about Bank Filtration (BF) that began in 2003, in Brazil. These studies were conducted in the laboratory and in the field with water and natural sediment from the study regions, showing how BF has been efficient worldwide for the treatment of water for public supply as an alternative treatment. It aims to show the synthesis of results to date and point out its main benefits and challenges; that is, the state of the art at the national level. The review is concentrated in Santa Catarina (part 1), Pernambuco and Minas Gerais (part 2). BF demonstrates efficiency in reducing parameters such as turbidity and coliforms (total and fecal), pesticides and toxins. However, BF showed low capacity in reducing parameters such as salinity and true color. BF is highly dependent on local geological conditions, so parameters such as iron, manganese, fluorine, alkalinity, hardness, and chlorides can be added to the treated water. Keywords: Water Treatment. Bank Filtration. Public Supply Systems. Natural Sediment. Water Quality.

Abstract Water supply systems, in particular small-scale water supply systems, are vulnerable to adverse events that may jeopardise safe drinking water. The consequences of contamination events or the failure of daily operations may be severe, affecting many people. In Norway, a 24-hour crisis advisory service was established in 2017 to provide advice on national water supplies. Competent and expert advisors from water suppliers throughout the country assist other water suppliers and individuals who may be in need of advice during an adverse event. This paper describes the establishment of this service and experiences from the first three years of its operation. Since the launch of the service, water suppliers across Norway have consulted it approximately one to two times a month for advice, in particular about contamination events and near misses. The outcomes have helped to improve guidance on water hygiene issues at the national level.

<p>Geological raw materials cover a wide range of materials from sand and gravel over granites and marbles to precious or critical metals and minerals. Man has extracted these materials from the (sub)surface since prehistorical eras, and these indispensable substances have to a very large extent contributed to the evolution of humankind.</p><p>In the latest decades, raw materials of economically and strategically importance for society but with high-risks associated with their supply, referred to as Critical Raw Materials (CRMs). To a large extent they form the basis for modern society as they are essential in key industry sectors. In the latest years, access to CRMs is a strategic security question for Europe’s road towards the green transition.</p><p>In September 2020, The European Commission launched a new list of CRMs as well as a strategy to enhance Europe’s resilience as most of these substances are sourced from other continents, and as the global competitions is increasing (EC, 2020). Among others, one of the suggested actions in this strategy is to ‘strengthen the sustainable and responsible domestic sourcing ……. in the European Union’. Although Europe has a long tradition of mining and extractive activities, it is acknowledged that there are several challenges to reach a situation with European sourcing of a certain amount of CRMs. Challenges include lack of interest in investment, strict permitting procedures or low levels of public acceptance. Nevertheless, it is recognized that the European geological conditions carry significant potential for CRMs, but more harmonised knowledge across borders is needed. This is where the Geological Survey Organisations of Europe play an important role as they are key partners in collecting and storing information on raw materials at national levels, and in making these available for endusers as policy and decision makers.  </p><p>All European countries have a national geological survey organization, some in addition a number of regional surveys. Most host data on raw materials, however, data are typically organized in different ways from one country to another based on different geological traditions and legal commitments. In the GeoERA MINTELL4EU project we build on previous projects as Minerals4EU, ProSUM, SCRREEN, ORAMA, and cooperate with ongoing projects as RESEERVE to collect raw material data in central database and to visualize these data in harmonized way at the European Geological Data Infrastructure (EGDI). Data includes, among other things, the location of individual mineral occurrences, mines, etc. stored in a central database called MIN4EU, and aggregated statistical data at national level on production, trade and reserves etc, compiled in what we know as the electronic Minerals Yearbook. The methods used for collecting (harvesting) and storing data will be discussed, and examples of harmonized visualizations will be shared.</p><p>MINTELL4EU is a part of the GeoERA programme supported by European Union's Horizon 2020, grant agreement no. 731166. </p>

This article addresses policy coherence for sustainable development demonstrating the important role that dashboards of interlinked indicators can play as tools to coordinate interrelated government ministries for integrated policymaking at national level. Specifically, a monitoring and coordination tool is proposed based on Sustainable Development Goals (SDGs) indicators and mappings of SDG responsibilities across ministries. Drawing on studies in sustainability science of SDG interlinkages, the article presents a five-step procedure that government departments can use to construct indicator sets from official SDG indicators to support integrated policymaking for a specific sector. I apply the method to Ireland’s marine sector. Ireland is an interesting case because although many countries report mapping SDG responsibilities across ministries, Ireland’s Voluntary National Review explicitly maps these responsibilities for all 17 SDGs and 169 targets. Using performance gap analysis, concrete recommendations are developed for the lead department of the marine along three dimensions: which departments to cooperate with, on what policy areas discussions should focus, and how Ireland performs in each area compared to a selection of peer countries. In particular, the article recommends cooperation with nine other departments on fifteen policy issues. Relative to peers, Ireland is ranked amongst sustainability “leaders” on three of these issues and amongst “laggards” on nine issues. The proposed procedure, which has wide application (to other countries and sectors) as a starting point for integrated policymaking, can help to raise awareness among policymakers of outcomes in linked policy areas and enable dialogue between ministries on coherent policies to address interrelated gaps in sustainability.

This paper examines the trend of matriculation in public basic education in the State of Santa Catarina between 1996 and 2010, a period when the policy of funds became effective in the financing of education at the national level. First Fundef in effect between 1998 and 2006, replaced by Fundeb, from 2007. We used the School Census microdata matriculation conducted annually by the National Institute of Educational Studies and Research Anísio Teixeira (INEP). The historical data show the growth of municipal networks due process of municipalization of primary education during the Fundef period and of early childhood education in Fundeb period, in contrast to the reduction in state care.

Os estudos quanto ao assédio moral no ambiente de trabalho são recentes no Brasil, pois datam de menos de 20 anos. Porém, embora recentes, vários autores vêm contribuindo de forma sistêmica para desvendar esse fenômeno quanto às causas e, principalmente, seus efeitos. Dessa forma, faz-se necessário analisar os estudos nacionais quanto às características das contribuições publicadas no meio científico, sobretudo, das ciências administrativas e áreas afins. O objetivo do presente artigo é elaborar um panorama geral da produção científica sobre assédio moral no âmbito nacional, tendo como delimitação da fonte de pesquisa os periódicos científicos nacionais. Para nortear o trabalho, de maneira sistêmica, os métodos foram balizados pelos princípios contidos nas leis que delimitam a análise bibliométrica. A ancoragem nas leis que formam a estrutura do rigor metodológico bibliométrico serviu para destacar aspectos intrínsecos da literatura nacional encontrada em revistas científicas. Os resultados mostram que ao considerar a mais importante base de indexação nacional, a Spell, é possível encontrar 46 trabalhos publicados em 27 diferentes periódicos, que foram elaborados por 93 autores. Além do mais, a Universidade Federal de Santa Catarina tem se apresentado como a mais profícua instituição de pesquisa, e o periódico Cadernos EBAPE.BR o meio de maior divulgação, dentre outros resultados. Por fim, a partir dos resultados encontrados, é possível evidenciar que a temática do assédio moral tem sido uma evidente fonte de pesquisa na área das ciências administrativas e áreas afim. Studies on moral harassment in the work environment are recent in Brazil, since they date from less than 20 years. However, although recent, several authors have contributed systemically to unravel this phenomenon regarding the causes and, mainly, their effects. Thus, it is necessary to analyze the national studies regarding the characteristics of the contributions published in the scientific environment, above all, the administrative sciences and related areas. The objective of this article is to elaborate an overview of the scientific production in moral harassment, at the national level, having as delimitation of the research source the national scientific journals. To guide the work, in a systemic way, the methods were marked by the principles contained in the laws that delimit the bibliometric analysis. The anchoring in the laws that form the structure of bibliometric methodological rigor served to highlight intrinsic aspects of the national literature found in scientific journals. The results show that when considering the most important national index base, Spell, it is possible to find 46 papers published in 27 different journals, which were elaborated by 93 authors. In addition, the Federal University of Santa Catarina has presented itself as the most profitable research institution, and the journal Cadernos EBAPE.BR, the most widely publicized medium, among other results. Finally, from the results found, it is possible to show that the issue of bullying has been an obvious source of research in the area of administrative sciences and related areas.
