Abstract Mining and milling processes could cause potential radiological exposures to the public. The objective of this study was to estimate the off-site radiological doses expected to be received by the public as a result of uranium mining and milling activities at Mkuju River Project in the United Republic of Tanzania. MILDOS-AREA was used to estimate off-site doses along with RESRAD-OFFSITE for comparison and verification. Since the mining has not yet started, the conceptual scenario was chosen. Using the concept of the most exposed individual, the location of the nearest residence (receptor) was chosen at 2.5 km from the site with other receptors being the fence boundary and grazing area being at 1.0 and 1.8 km, respectively. Yellowcake stack (point source), ore pad and two tailing piles where each had an area of 2.5 × 105 m2 were chosen to be the source of radiological contamination. The radiological source term was obtained from the concentration of 226Ra and 232Th in soil obtained from the previous studies of environmental impact assessments. Meteorological and site-specific data were used for this analysis. The estimated total effective dose equivalent (TEDE) for the nearest residence which was calculated by MILDOSE-AREA ranged from 2.5 × 10−2 to 4.45 × 10−2 mSv/y during the operation of 13 y. The result of RESRAD-OFFSITE ranged from 7.19 × 10−2 mSv/y for the first year to 7.43 × 10−2 mSv/y in the final year. This implied all the estimated TEDEs were below the dose limit and dose constraint of 1 and 0.3 mSv/y, respectively, as suggested by the International Atomic Energy Agency. Hence, it was found that there was no potential radiological concern of uranium mining at Mkuju River Project. It was found that using MILDOS-AREA it is possible to estimate dose at different distances from the facility. Therefore, this study apart from estimating the off-site doses, it can be used for planning of public and social premises before the commencement of the project. That is the distance from the facility where the public should be located as well as other locations for social activities.

The labour market effects in Southeast Asia of the COVID-19 pandemic have attracted considerable analysis from both scholars and practitioners. However, much less attention has been paid to the pandemic’s impact on legal protections for workers’ and unions’ rights, or to what might account for divergent outcomes in this respect in economies that share many characteristics, including a strong export orientation in labour-intensive industries and weak industrial relations institutions. Having described the public health measures taken to control the spread of COVID-19 in Indonesia, Cambodia and Vietnam, this article analyses governments’ employment-related responses and their impact on workers and unions in the first year of the pandemic. Based on this analysis, we conclude that the disruption caused to these countries’ economies, and societies, served to reproduce existing patterns of state–labour relations rather than overturning them.

Abstract The mobile app Schnëssen establishes a digital and participatory research platform to collect data on present-day spoken Luxembourgish through crowdsourcing and to present the results of data analysis to the general public. Users can participate in different kinds of audio recording tasks (translation, picture naming, reading, question) as well as in sociolinguistic surveys. All audio recordings are accessible to the public via an interactive map, which allows the participants to explore variation in Luxembourgish themselves. In the first year of data collection, roughly 210.000 recordings have be collected covering numerous variation phenomena on all linguistic levels. Additionally, over 2800 sociolinguistic questionnaires have been filled out. Compiling such amounts of data, the Schnëssen app represents the largest research corpus of spoken Luxembourgish.

Abstract This paper discusses the impact of several spelling changes in Croatian on the level of the literacy of native speakers. Since 1986, there have been five official recommendations for usage that pertain to five different orthographic manuals. This research focuses on three spelling points with considerable identity-related repercussions among the public and the media, which are sometimes named the spelling symbols of Croatian. A questionnaire-survey comprised of 36 tests was completed among 1063 students on a technical study programme each year for eight consecutive academic years. Eight generations of first-year undergraduates, who do not study language in an educational setting, have accepted the new spellings, contingent on a frequency principle. The more frequent a spelling variant occurs, the less the chance that the new spelling variant is accepted, and vice versa. Given the lack of established and enduring spelling norms, combined with ideological oppositions between the old and new spelling forms, students have been guided mainly by their capacity to write the most common form.

Nataliе’s Ramonda, a symbol of Armistice Day – November 11 in Serbia, is a new memorial symbol constructed and promoted by politicians in 2012. The Armistice Day was celebrated then as a national holiday in Serbia. The reception of this symbol has been explored over a five-year period, both in a public discourse and on a representative sample of first year students at the Faculty of Philosophy in Belgrade. In public discourse, as well as among students of the Faculty of Philosophy, Natalie’s Ramonda is perceived as an emblem, a badge, and most often as a symbol. It was seen as an emblem on the lapel of public and media figures, inaccessible to broad commercial promotion and sales. In public discourse and among students at the Faculty of Philosophy, Natalie’s Ramonda was perceived in several answers as a medal, and is also recognized as a flower that symbolizes the suffering of the Serbian people in World War One; symbol of the nation’s rebirth – the flower phoenix, as a mark of peace and freedom. As a newly constructed symbol of the Armistice Day in Serbia, for the past seven years, Natalie’s Ramonda has been a mediator in the public culture of remembrance and in the ongoing process, by becoming a part of cultural memory.

There are myriad benefits to science departments that have a public engagement in science portfolio in addition to any recruitment of new undergraduates. These benefits are discussed in this paper and include: improving congruence between A level and first year undergraduate courses, training in science communication and the breaking down of barriers between the public and universities. All activity requires investment of personnel and incurs a financial cost. Small scale activities may be able to absorb this cost, but ultimately as the portfolio grows this will become an increasing drain on resources. Bristol ChemLabS Outreach has, from the very start, set out to be fully sustainable financially and in terms of personnel. A very important component is the full support of the senior management team. In this paper we discuss how we have achieved this.

Jacobus Eliza Johannes Capitein (1717-1747) was a man of many firsts-the first black student of theology at the University of Leiden in the Netherlands, the first black minister ordained in the Dutch Reformed Church in the Netherlands, the author of the first Fante/Mfantse-Dutch Grammar in Ghana as well as the first translator of the Ten Commandments, Twelve Articles of Faith and parts of the Catechism into Fante/Mfantse. However, he is also remembered as the first African to argue in writing that slavery was compatible with Christianity in the public lecture that he delivered at Leiden in 1742 on the topic, De Servitute Libertati Christianae Non Contraria. The Latin original was soon translated into Dutch and became so popular in the Netherlands that it was reprinted five times in the first year of publication. This contribution will pose the question: Was Capitein a sell-out who soothed the Dutch colonial conscience as he argued with scholarly vigour in his dissertation that the Bible did not prohibit slavery and that it was therefore permissible to continue with the practice in the eighteenth century; or was he resisting the system by means of mimicry due to his hybrid identity - as an African with a European education - who wanted to spread the Christian message and be an educator of his people?

Marcel Breuer was in the first year of architectural technicians to graduate from Bauhaus School. The peculiar education he received there allowed him to explore the concept of design in its broadest sense. In his European stage we find, on the most private and small scale, unique solutions for furniture. In his first American stage we see a strong commitment with solutions related to the residential land and, when he earned international recognition, he developed large scale solutions for his public non-residential buildings and urban equipments in locations all over the world. It is strange to see that an architect like him did not have the opportunity to materialize any of his proposals associated with the public space. The 1945 Cambridge Servicemen’s Memorial project, also known as the Memorial War, is the most significant one he developed in his last years in Cambridge. Had it been built, it would have been a valuable example of modernity and contemporary reinterpretation of the monument in the public space.

In the framework of the 4.0 Industrial Era that focuses on technological advances in the present, nuclear technology for peaceful purposes by promoting safety and security of workers and the public and its environment becomes very important. In the use of nuclear technology, safety and security governance are important things to be aware of because expectations and reality are often not appropriate. The purpose of research is to formulate the governance of safety and security programs of the use of nuclear technology in Indonesia by understanding the interaction and contextual relationships 3 elements of purpose, constraints and institutional, and identifying sub-elements that have High power drivers and low dependence. It is necessary as an alternative material in the preparation of regulation and nuclear safety facing the Industrial Era 4.0. The method used is the Interpretive Structural Modeling (ISM) analysis. ISM analysis is intended to illustrate the structure of the nuclear technology safety and security governance Program. The research results of the key purpose elements are the safety assurance of workers, communities and the environment. To achieve these key objectives, elements of key constraints are weak in the implementation of occupational safety culture and have not been in fact dissemination of the implementation of nuclear technology in the general public. A key institutional element that is involved in the implementation of the safety and security management program of nuclear technology is the National Nuclear Energy Agency (BATAN). Data processing results of expert opinion is the consistency of 93-100%.
