Comment les migrations affectent-elles la mortalité infanto-juvénile en zone rurale ? L’exemple de Niakhar, Sénégal
Authors: Nguemdjo Ulrich , Ventelou Bruno
Published: November 2021

Explorant les riches données longitudinales fournies par l’Observatoire de santé et de population de Niakhar, cette étude examine les effets des migrations sur la mortalité infanto-juvénile dans les familles rurales restées au village. Les migrations, en particulier de courte durée, sont associées de manière positive aux chances de survie des enfants de moins de cinq ans au sein du ménage. On constate également que les déplacements de courte durée des femmes d’âge actif ont plus d’incidences sur la mortalité des enfants que ceux de leurs homologues masculins. De surcroît, des effets croisés sont identifiés entre ménages de la même concession, ce qui est conforme à l’idée que les familles rurales africaines partagent les gains de l’émigration avec une communauté étendue de voisins. Enfin, l’effet des migrations maternelles de courte durée sur la survie des enfants de moins de cinq ans demeure globalement positif, mais nettement plus modeste. L’émigration de la mère, en particulier pendant la grossesse, semble améliorer la probabilité de survie des enfants juste après la naissance, mais celle-ci tend à diminuer après l’âge d’un an et lorsque la mère est absente.
Gestion du fait religieux et injonctions d’inclusion : une source de tensions de rôle pour les managers de proximité ? Étude de la question du port du voile au sein d’une grande entreprise française de télécommunications
Authors: Volia Jean-Christophe
Published: November 2021

La gestion du fait religieux est un sujet montant dans la littérature française depuis les années 2010. Parmi les faits religieux au travail les plus recensés, l’édition 2021 de l’enquête annuelle de l’Institut Montaigne désigne le port visible d’un signe religieux, confirmant la tendance des études précédentes. Ces dernières années, plusieurs affaires médiatisées en France font écho à cet état de fait. Elles mettent systématiquement en exergue des situations liées au port du voile islamique : comme Etam et Décathlon en 2019. Globalement une intervention sur le sujet religieux est plus délicate que sur d’autres pour les managers, notamment en cas de conflit avec un salarié (Institut Montaigne, 2021). Les entreprises sont alors de plus en plus nombreuses à proposer à leurs managers de proximité des dispositifs d’aide à la gestion du fait religieux. Ils officialisent la posture de l’organisation sur le fait religieux, et son approche de la diversité. Les managers de proximité se retrouvent en effet au carrefour des attentes de plusieurs émetteurs. Ils sont à la fois garants de la politique de l’entreprise et premier relai des revendications des salariés. Notre étude questionne donc les tensions de rôle que ces managers peuvent ressentir face à la gestion des pratiques religieuses des salariés, ce à travers le cas du port du voile. Une observation participante de trois ans au sein d’une grande entreprise française de télécommunications, nous a permis d’analyser son dispositif de gestion du fait religieux et de mener 66 entretiens semi-directifs, dont 41 auprès de managers.
Les mises en ligne du travail domestique : une étude de comptes Facebook en milieu populaire
Authors: Pasquier Dominique
Published: November 2021

À partir de l’analyse des échanges et des liens partagés sur 46 comptes Facebook d’ouvrier·e·s et d’employé·e·s dans le secteur des services, cet article étudie, dans une perspective genrée, la production et la réception des messages concernant le travail domestique. On peut distinguer trois types de prise de parole sur le sujet : des plaintes sur la lourdeur des tâches venant de femmes sous la forme de messages rédigés qui déclenchent une chaîne de réactions empathiques entre femmes ; des panneaux trouvés en ligne qui revendiquent une reconnaissance du travail accompli par les femmes qui ne circulent que dans les comptes féminins; et des caricatures ou des histoires drôles contre la domination masculine qui peinent à trouver leur public. L’article constate la grande absence d’interlocuteurs masculins dans les échanges et pose la question des conditions d’une montée, dans les milieux populaires, d’aspirations à plus d’égalité formulées par des femmes qui trouvent un aussi faible écho chez les hommes.
Qui lave le linge sale de la famille ?
Authors: Stambolis-Ruhstorfer Michael , Gross Martine
Published: November 2021

Cet article étudie la répartition des tâches ménagères au sein de couples hétéroparentaux et homoparentaux en France. Il mobilise les données quantitatives de l’étude Elfe (Étude longitudinale française depuis l’enfance) et de Devhom (Homoparentalité, fonctionnement familial, développement, et socialisation des enfants). Jusqu’à présent, la littérature comparative a étudié le travail domestique comme un bloc. En détaillant six tâches, notre analyse dégage des schémas genrés précis qui, à partir de ces échantillons, distinguent les deux types de familles. Alors que les couples homoparentaux enquêtés partagent le travail domestique plus équitablement ou le font ensemble, les couples hétéroparentaux de l’échantillon étudié instaurent une assignation genrée des tâches que les mères assument seules, à l’exception des réparations et de la vaisselle. Ainsi, ces familles homoparentales semblent moins reproduire les normes qui traduisent la domination masculine de la distribution des tâches.
Concepción espacial y literatura emblemática en los dramas pastoriles de Lope de Vega
Authors: Sáez Raposo Francisco
Published: November 2021

El presente artículo establece vínculos entre la cultura conceptual e iconográfica que surgió a partir de la publicación del Emblematum Liber de Andrea Alciato en 1531 y los dramas pastoriles escritos por Lope de Vega entre 1590 y 1615 aproximadamente. El objetivo definitivo no es solo encontrar menciones a ciertos emblemas a nivel textual. La intención es, incluso, ir un poco más lejos, esto es, tratar de establecer, a partir de la representación de unos «modos de ver», conexiones entre determinadas concepciones escénicas y casos concretos incluidos en la literatura emblemática. En otras palabras, determinar la impronta visual con la que Lope concibió algunas de las escenas de sus dramas pastoriles.
Persistencia y reescritura del canon picaresco: El azar y viceversa, de Felipe Benítez Reyes
Authors: Vadillo Buenfil Carlos
Published: November 2021

Este artículo analiza las correlaciones y los distanciamientos discursivos y argumentales entre narraciones de la picaresca canónica y la más reciente novela de Felipe Benítez Reyes. En la actualización de la propuesta picaresca, El azar y viceversa (2016) trasluce rasgos de las novelas posmodernas: autoconciencia, ironía, parodia, intertextualidad, «metaficción historiográfica», mestizaje genérico, descreimiento de las utopías, desarraigo espacial del héroe e inestabilidad ontológica; estos elementos nos guían para inscribirla en la neopicaresca de la contemporaneidad. En suma, como planteó Alonso Zamora Vicente sobre las ficciones continuadoras de lo picaril, examinaremos en qué medida El azar y viceversa se sujeta a los relatos truhanescos, y mediante qué maniobras se aparta del canon, lo matiza o le otorga otra dimensión.
Knowledge Sharing and the Improvement of Service Delivery in an Academic Library
Authors: Tahleho Tšeole Emmanuel , Ngulube Patrick
Published: November 2021

Knowledge can play an important role in ascertaining an organization’s competitive edge if the knowledge of employees is nurtured and utilized as an asset with a potential to improve service delivery. The study focused on knowledge sharing at the Thomas Mofolo Library in Lesotho to determine if knowledge sharing was being used to improve service delivery at the Library. A case study design that triangulated interviews and questionnaires was used in this study. Quantitative data was processed using software packages. Data from the interviews was analyzed through content analysis based on the objectives of the study. This study established that staff recognized the need to share knowledge. However, knowledge sharing occurred on an ad hoc basis. There was a limited use of technology-based and human-based mechanisms of sharing knowledge. The study suggests practical knowledge-sharing practices that may contribute to improved service delivery in a library setup. As a case study, study may also contribute to the development of theory about the phenomenon.
Formate Esters Containing Biodiesel - Diesel Mixed Fuels
Authors: Kampars Valdis , Naumova Anastasija
Published: November 2021

The blends of varying proportions of biodiesel (FAME) containing formate esters of glycerol and 93.0 wt.% fatty acid methyl esters, obtained in an interesterification reaction with methyl formate without further purification, and winter diesel fuel, were prepared, analyzed and compared with winter diesel fuel. The obtained results showed that blends comprising up to 20 vol.% of FAME fulfill the requirements of the standard LVS EN 590 concerning such characteristics as cold flow properties, viscosity, density, and carbon residue. The increase of FAME content worsens the cold flow properties; however, the mixed fuel with 20 vol.% or lower FAME content, according to the cloud point and cold filter plugging point values, remains in the same severe climate "Class 0" group as winter fuel. The carbon residue of mixed fuels raises with increasing FAME content, but stay low and do not exceed the limits of standard for mixtures with FAME percentage up to 20 vol.%. The comparison of mixed fuels containing 20 vol.% of FAME and the same amount of neat biodiesel (99.6 wt.% of fatty acid methyl esters) shows that the difference is negligible. The obtained results have indicated a good potential of FAME obtained in the interesterification reaction with methyl formate without further purification as a diesel fuel additive for up to 20 vol.%.
Retinopathy of prematurity in Ardabil, North West of Iran: Prevalence and risk factors
Authors: Fekri Yousef , Ojaghi Habib , Momeni Neda , Amani Firouz
Published: November 2021

Retinopathy of prematurity (ROP), which affects the retina of premature infants, is a leading cause of blindness in premature infants worldwide. The aim of this study was to evaluate the frequency and risk factors of retinopathy of prematurity infants referred to Alavi hospital between October 2018 and October 2019. In the present study, 400 infants with gestational age less than 34 weeks and or birth weight of 2000 g or less were enrolled in the study. Required information including sex, gestational age, maternal age, birth weight, type of delivery, oxygen therapy, septicemia, multiple gestations, consanguineous marriage, respiratory problem, and blood exchange were extracted from their hospital records and then included in the data collection form. These infants were also examined for ROP, stage and area of involvement by an experienced ophthalmologist and then classified into two groups including retinopathy and healthy group. Finally, the data were analyzed in SPSS 25 software using chi-square, fisher exact test, t-test, binary logistic regression, and ROC curve analysis. Of the 400 preterm infants studied (57.2% male and 42.8% female), 107 (26.8%) infants had ROP of whom 23 (21.5%) needed treatment (i.e. 5.8% of all infants need treatment). There were 4 (3.7%), 29 (27.1%), and 74 (69.2%) infants with zone I, II, and III, respectively. There were 91 (85%), 11 (10.3%), and 5 (4.7%) infants with stage I, II, and III, respectively. Multivariate logistic regression analysis showed that parental consanguinity (OR=2.263, 95%CI: 1.240-4.130, P=0.008), gestational age less than 32.5 weeks (OR=4.067, 95%CI: 2.340-7.069, P<0.001), and birth weight less than 1725 g (OR=4.522, 95%CI: 2.677-7.637, P<0.001) were associated with a 2.3-fold, 4.1-fold, and 4.5-fold increased risk of ROP, respectively. ROP had no significant relationship with other variables. In summary, the findings of the present study showed that one quarter of the premature infants had ROP. Furthermore, birth weight less than 1725 g, gestational age less than 32.5 weeks, and parental consanguinity were risk factors for ROP, in addition, one-fifth of the infants with ROP needed treatment.

В предположении, что решение $u(x,t)$ этого уравнения существует, его можно представить как единственное решение матричной задачи Римана-Гильберта на плоскости комплексного спектрального параметра $\xi$. Матрицы скачков определяются спектральными функциями, которые не являются независимыми, а связаны глобально.
Неравенства чебышeвского типа и принципы больших уклонений
Authors: Borovkov Alexander Alekseevich , Logachov Artem Vasil'evich , Mogul'skii Anatolii Al'fredovich
Published: November 2021

Пусть $\xi_1,\xi_2,…$ - последовательность независимых копий случайной величины $\xi$,
$$
S_n=\sum_{j=1}^n\xi_j, \qquad A(\lambda)=\ln\mathbf{E}e^{\lambda\xi},
$$
$\Lambda(\alpha)=\sup_\lambda(\alpha\lambda-A(\lambda))$ есть преобразование Лежандра над функцией $A(\lambda)$.
В настоящей работе, которая носит отчасти обзорный характер, рассматриваются обобщения известных экспоненциальных неравенств чебышeвского типа
$$
\mathbf{P}(S_n\geq\alpha n)\leq\exp\{-n\Lambda(\alpha)\}\quad при \alpha\geq\mathbf{E}\xi,
$$
для следующих трех объектов:
I. суммы случайных векторов;
II. случайные процессы (траектории случайных блужданий);
III. случайные поля, ассоциированные с графами Эрдeша-Реньи с весами.
Показано, что эти обобщения позволяют получить неулучшаемые оценки сверху для вероятностей попадания в выпуклые множества, а также доказывать принципы больших уклонений для объектов, перечисленных в I-III.
Optimal stopping, randomized stopping and singular control with general information flow
Authors: Agram Nacira , Haadem Sven , Oksendal Bernt , Proske Frank
Published: November 2021

В этой статье мы преследуем двоякую цель. Во-первых, мы распространяем хорошо известное соотношение между оптимальной
остановкой и рандомизированной остановкой заданного случайного процесса на ситуацию, когда доступный поток информации - это фильтрация, которая априори не предполагается как-либо связанной с фильтрацией случайного процесса. В этом случае мы говорим об оптимальной остановке и рандомизированной остановке при общем потоке информации. Во-вторых, следуя идее Н. В. Крылова (1977), мы вводим специальную задачу сингулярного стохастического управления с общей информацией и показываем, что она эквивалентна задачам оптимального управления и рандомизированного управления с частичной информацией. Далее мы показываем, что решение указанной задачи сингулярного управления может быть выражено в терминах вариационных неравенств для частичной информации.
Conrad’s Artistic Returns: Perspectives on a Bulgarian Debut in Staging Heart of Darkness
Authors: Grigorova Margreta , Tsoneva Petya
Published: November 2021

Since 1989 (the fall of Communism) the performing arts in Bulgaria have suffered a long process of transition dominated by a certain dialectic tension between the necessity to meet economic needs and the desire to open new venues for dramatic art. Against this background and contributing its own perceptive “reading” of Heart of Darkness to Conrad’s Bulgarian reception, on the eve of the vigorous celebration of his 160th anniversary in 2017, stage director Valeria Valcheva’s theatrical adaptation represents a remarkable debut rendition of Conrad’s fiction. The aim of this article is to explore how her idiosyncratic, creative, poetically recognizable approach lends a new form to Conrad’s recurrent relocation in modern and contemporary Bulgarian art.

* The present article complements, expands and rethinks the authors’ latest study of the Bulgarian dramatization of Heart of Darkness, published in Bulgarian in Proglas journal, aiming to contribute to the discussions of Conrad’s reception in a wider academic space. See Margreta Grigorova and Petya Tsoneva, “ ‘Sartseto na mraka’—idei i resheniya na parvata balgarska postanovka” [Heart of Darkness on the Bulgarian Stage: Creative Perspectives and Techniques], Proglas 28, no. 1 (2019), pp. 35-46.

The Theological Significance of the Concept of Anointing in Contemporary Churches in Nigeria
Authors: Oderinde Olatundun Abosede
Published: November 2021

Anointing is a popular concept in most Pentecostal Churches in Nigeria today. It is common to hear sayings such as “falling under anointing”, “transfer of anointing”, “anointing service”, “anointing for favour”, “anointing for sickness”, “anointing for breakthrough”, and many more. There is a wide spread confusion within the Pentecostal movements regarding anointing. There is no common accepted meaning. There is no uniformity in understanding how one may obtain whatever the anointing is, there is even a great disagreement about who really is anointed. The main reason for this misunderstanding in most cases is because everyone is holding to a different interpretation of the Bible. The study examines the concept of anointing from the Biblical perspective in the context of the practice of anointing in contemporary Pentecostal churches in Nigeria. The study adopted the contextual and narrative analytical method to investigate the historical and contemporary contexts of the use of anointing and its practice in the church today. The study shows that spiritual anointing with the Holy Spirit was conferred on Christians by God (2Cor1:21) and they were described as having an unction from God by which they know all things (1 John 2:20, 27) but there was no indication in the Scriptures that anyone can transmit the anointing by any means as it is being practised in the church today.

Este artigo tem o objetivo de investigar articulações entre textos multimodais digitais apresentados em propostas de redação do Programa Desafio Nota 1000 — 2ª e 5ª edições realizadas pela Secretaria de Educação, Ciência e Tecnologia da Paraíba (SEECT/PB) em 2021 — e orientações para leitura e produção textual visando à prática dos estudantes para escrita de texto dissertativo-argumentativo em modelo proposto pelo ENEM. Para tanto, analisamos a multimodalidade em duas propostas de redação veiculadas em ambientes digitais, a partir da disposição de textos motivadores verbo-visuais, em consonância com as metafunções da Gramática do Design Visual (GDV), de Kress e van Leeuwen (1996, 2006, 2021). Em uma perspectiva teórico-metodológica, situamos o estudo no campo da Linguística Aplicada, com base em discussões de autores como Hodge e Kress (1988), Cope; Kalantzis (2000), Kress (2001, 2003, 2010), Silva (2016), entre outros, acerca da Multimodalidade e da Semiótica Social, a partir de uma abordagem qualitativa de cunho descritivo e interpretativista. Os resultados demonstraram que os alunos precisam estar inseridos em um ambiente de práticas de letramentos visuais para produzirem sentidos, a partir da relação de significados sociais entre os textos verbais e não verbais. Desse modo, concluímos que a formação de leitores/produtores de textos multimodais nessas propostas, faz-se indispensável, tendo em vista a necessidade de que os participantes desenvolvam maior proficiência na leitura crítico/visual dos textos motivadores, permitindo assim uma produção escrita condizente não apenas à matriz avaliativa do ENEM, mas também à produção de sentidos inerente a todo texto multimodal.

Published: November 2021

This study attempts to analyze the extent of service quality and customer loyalty in private banks. For any bank to grow and develop sustainably, they need to ensure their customer’s satisfaction in which service quality plays a decisive role. Satisfied customers, similarly, provoke customer’s loyalty towards their banks that can then enhance the profitability of Banks. With the help of the SERVQUAL Model, the study also traces various factors considered when measuring customer satisfaction. The primary data were collected with the help of a standardized questionnaire on the said topic, which conveniently collected a sample of 200 respondents accessing private banking services in different cities of India. The collected data are analyzed with the statistical tools of Factor Analysis, Reliability, and Validity tests with the help of SPSS.

metamorfosis de la derecha salvadoreña
Authors: Miranda Baires Danilo , Reserve Roody
Published: November 2021

Este artículo analiza la trayectoria de la derecha en El Salvador a lo largo de dos siglos de vida independiente. Los autores argumentan que esta corriente política ha dominado ampliamente e impuso sus ideales sociales, económicos y políticos a través del control del aparato estatal, el uso de la fuerza militar y la hegemonía cultural y social. La lucha entre izquierda y derecha es tratada aquí como una pugna de incorporación y de redistribución. El texto recorre el período de independencia y el surgimiento de la república cafetalera, prosigue con la dictadura militar como coraza del régimen oligárquico, continúa con el conflicto armado y el proyecto contrainsurgente, examina el período posterior a los Acuerdos de Paz y analiza el panorama actual tras la llegada al poder de Nayib Bukele y su movimiento Nuevas Ideas, que han llegado a controlar casi en su totalidad los poderes públicos. Se ha podido observar que ha habido una metamorfosis a lo largo de la historia política del país, pasando de una derecha más esquemática y predecible a una que se caracteriza por una ambigüedad y una amorfia ideológica tales que vuelven difícil cualquier prospectiva sobre su rumbo y su orientación programática en el largo plazo. Sin embargo, es posible identificar algunos de los grandes rasgos definitorios de la actual derecha gobernante y sugerir algunas interpretaciones sobre su perfil.

Entrainment and deposition of boulders in a gravel bed river
Authors: Allemand Pascal , Lajeunesse Eric , Devauchelle Olivier , Langlois Vincent
Published: November 2021

Abstract. Rivers transports coarse sediment (gravel, cobbles, or boulder) as bedload. During a flood, when the discharge is high enough, the sediment grains move by rolling and bouncing on the river bed. Measuring bedload transport in the field is notoriously difficult. Here, we propose a new method to characterize bedload transport by floods. Using a drone equipped with a high resolution camera, we recorded yearly images of a bar of the Vieux-Habitants river, a gravel-bed river located on Basse-Terre Island (Guadeloupe, French West Indies). These images, combined with high frequency measurements of the river discharge, allow us to monitor the evolution of the population of boulders on the river bed. Based on this dataset, we estimate the smallest discharge that can move the boulders, and calculate the effective transport time of the river. We find that transport occurs about 10 hours per year. When plotted as a function of this effective transport time, likelihood of a given boulder remaining at the same location decreases exponentially, with an effective residence time of 17 hours. We then propose a rough estimate of the average number of boulders that the river carries every year.

Abstract. Regional assessments provide a large-scale comparable vision of the threat posed by multiple sources and are useful for prioritising risk-mitigation actions. There is a need for such assessments from international, regional and national agencies, industries and governments to prioritise where further study and support could be focussed. Most existing regional studies on the threat posed by volcanic activity have relied on concentric radii as proxies for hazard footprints and have focused only on population exposure, often using indices to make first-order estimates of exposure. However, this approach is an oversimplification of volcanic hazards and their associated impacts. We have developed and applied a new approach that quantifies and ranks exposure to multiple volcanic hazards for 40 high-threat volcanoes in Southeast Asia. For each of our 40 volcanoes, hazard spatial extent, and intensity where appropriate, was probabilistically modelled for four volcanic hazards across three eruption scenarios, giving 697,080 individual hazard footprints plus 19,560 probabilistic hazard outputs. We then developed a GIS framework to overlay the spatial extent of probabilistic hazard footprints with open-access datasets across five exposure categories. Finally, we used our calculated exposure values to rank each of the 40 volcanoes in terms of the threat they pose to surrounding communities. We present VolcGIS, an open-source Python code that implements all of the spatial operations required for exposure analysis, available at github.com/vharg/VolcGIS. We provide all our outputs - more than 6,500 geotif files and 70 independent estimates of exposure to volcanic hazards across 40 volcanoes - in user-friendly format. Results highlight that the island of Java in Indonesia has the highest median exposure to volcanic hazards, with Merapi consistently ranking as the highest threat volcano. Hazard seasonality, as a result of varying wind conditions affecting tephra dispersal, leads to increased exposure values during the peak rainy season (January, February) in Java, but the peak dry season (January, February, March) in the Philippines. A key aim of our study was to highlight volcanoes that may have been overlooked, perhaps because they are not frequently or recently active, but that have the potential to affect large numbers of people and assets. It is not intended to replace official hazard and risk information provided by the individual country or volcano organisations. This study and the tools developed provide a road map for future multi-source regional volcanic exposure assessments, with the possibility to extend the assessment to other geographic regions and/or towards impact and loss.
Overview of Post-Closure Criticality Safety – RD&D Topics in Switzerland
Authors: Wittel Madalina , Pudollek Susanne
Published: November 2021

Abstract. The demonstration of post-closure criticality safety of spent nuclear fuel in a deep geological repository is a regulatory requirement in Switzerland and many other countries. One of the main challenges stems from the very long timescale (1 million years in Switzerland) that has to be considered. Nagra, the Swiss National Cooperative for the Disposal of Radioactive Waste, is presently elaborating the technical and scientific foundation of the criticality safety assessment in view of the upcoming general licence application for the Swiss Spent Fuel and HLW repository. In this context, Nagra supports and pursues a focussed RD&D programme in collaboration with several renowned research institutes. Nagra's safety concept relies on natural and technical barriers. For the initial thermal phase of the repository, a steel canister assures complete containment of the spent fuel. The canisters are foreseen to remain intact for approximately 10 000 years; however, the subcriticality of the system has to be ensured for a much longer period. In this context, an important part of the research activities pursued by Nagra address the nearfield evolution and the formulation of scenarios for the corresponding evolution of the canister and spent fuel system. The role that variations in the canister design and material composition have on the system's reactivity are also investigated. Other research topics focus on developing a reliable methodology for carrying out the criticality safety assessment. This symposium contribution gives an overview of the post-closure criticality RD&D activities pursued and envisioned by Nagra. The general context and Nagra's fundamental approach to elaborating the current phase of the criticality safety assessment are presented first. Following this, the current RD&D landscape and the most important technical considerations underpinning Nagra's technical basis for the post-closure criticality safety assessment in particular are discussed. Future planned research topics and points of interest are also presented as an outlook of this presentation.
Spatially resolved sorption of Cm(III) on crystalline rock: influence of surface roughness and mineralogy
Authors: Demnitz Maximilian , Molodtsov Konrad , Schymura Stefan , Schierz Ariette , Müller Katharina , Schmidt Moritz
Published: November 2021

Abstract. Many countries will use deep
geological repositories to dispose of highly active nuclear waste. Crystalline
rock is a potential host rock because of its strong geotechnical stability,
low permeability and low solubility; however, its inherent mineralogy is
heterogeneous, consisting of a wide set of minerals in varying
amounts. Therefore, there is a need for using sophisticated techniques that
allow spatial resolution to characterize the nanostructure of such crystalline
rock surfaces and the speciation of the actinides therein. As a representative
for trivalent actinides, such as Am(III), Np(III), and Pu(III), which are
expected to be present due to the reducing conditions encountered in a deep
geological repository, we have chosen the actinide Cm(III). Cm(III) possesses
excellent luminescence properties, which allows us to not only examine the
sorption uptake but also the speciation of Cm(III) on the surface. We combined spatially resolved investigation techniques, such as vertical
scanning interferometry, calibrated autoradiography, and Raman microscopy
coupled to micro-focus time-resolved laser-induced luminescence spectroscopy
(µTRLFS) (Molodtsov et al., 2019). Thus, we were able to correlate
mineralogy, surface roughness, and grain boundary effects with radionuclide
speciation, allowing us to identify important radionuclide retention processes
and parameters (see Fig. 1). Investigations focused on granite from Eibenstock (Germany) and migmatised
gneiss from Bukov (Czech Republic). Cm(III) sorption on the rock's
constituting minerals – primarily feldspar, mica and quartz – was analyzed
quantitatively and qualitatively. We observed that Cm(III) sorption uptake and
speciation depends not only on the mineral phase but also the surface
roughness (Demnitz et al., 2021). An increasing surface roughness leads to
higher sorption uptake and a stronger coordination of the sorbed Cm(III). On
the same mineral grains sorption differed significantly depending if an area
exhibits a low or high surface roughness. In the case that one mineral phase
dominates the sorption process, sorption of Cm(III) on other mineral phases
will only occur at strong binding sites, typically where surface roughness is
high. Areas of feldspar and quartz with high surface roughness additionally
showed the formation of sorption species with particularly high sorption
strength that could either be interpreted as Cm(III) incorporation species or
ternary complexes on the mineral surface (Demnitz et al., 2021). We conclude that in addition to mineral composition, surface roughness needs
to be adequately considered to describe interfacial speciation of contaminants
and respective retention patterns for the safety assessments of nuclear waste
repositories.
Reactive transport modelling of long-term interactions between iron and MX-80 bentonite

Abstract. The geological disposal in deep bedrock repositories is the preferred option
for the management of high-level radioactive waste. In some of these concepts,
carbon steel is considered as potential canister material and bentonites are
planned as backfill material to protect metal waste containers. Therefore, a
1D radial reactive transport model has been developed in order to better
understand the processes occurring during the long-term iron–bentonite
interaction. The conceptual model accounts for diffusion, chemistry of the
porewater and aqueous complexation reactions, mineral
dissolution/precipitation and absorption, at a constant temperature of
25 ∘C under anoxic conditions. The geometry of the axisymmetric model
reflects the canister–bentonite interface and the bentonite. The primary
phases considered are montmorillonitic smectite, quartz, muscovite, albite,
illite, pyrite and calcite. We assume that carbon steel is composed only of
iron. The potential secondary phases considered are from reported experiments,
such as magnetite, nontronitic smectite, greenalite, cronstedtite and
siderite. The numerical model results suggest that at the iron–bentonite
interface, Fe is adsorbed at the smectite surface via ion exchange in the
short term and it is consumed by formation of the secondary phases in the long
term. Furthermore, calcite precipitates are due to cation exchange in the
short term and due to montmorillonitic smectite dissolution in the long
term. The numerical model predicts the precipitation of nontronitic smectite,
magnetite and greenalite as corrosion products. Results further reveal a
significant increase in pH in the long term, whereas dissolution/precipitation
reactions result in limited variations of the porosity. Progressing bentonite
dissolution owing to the rising pH and concomitantly increasing silicate
concentrations in the porewater induce formation of Fe-silicates as corrosion
products at the expense of magnetite. A sensitivity analysis has also been
performed to study the effect of selected parameters, such as corrosion rate,
diffusion coefficient and composition of the porewater, on the corrosion
products. Overall, outcomes suggest that pH and concentration of dissolved Si
play an important role in corrosion mechanisms. The predicted main secondary
phases in the long term are Fe-silicate minerals. Thus, such phases deserve
further attention as possible chemical barriers for radionuclide migration in
the repository near-field.
Radioactive waste management ethics and public policy: a precautionary approach
Authors: Oross Daniel , Zala Miklos , Matyas Eszter
Published: November 2021

Abstract. The focus of the project is on how to regulate risky technologies, both old
(such as nuclear waste management) and new (such as geoengineering). Thus, the project is aimed at contributing to a better understanding of the ethical, political, and socio-economic aspects of radioactive waste management-related risks. The goal of the project is to contribute to the current discussions on the case of the expansion of the Hungarian Nuclear Power Plant. The Paks II project allows us to present how to set up procedures where some radioactive waste-related risks will not derail decision-makers and how they can be held accountable by the public. The case of Paks II is also compelling; as of today there are only 19 countries in the world that are in the process of new reactor building (World Nuclear Association, 2021). The project is aimed at providing and defending a precautionary approach to
radioactive waste management because it involves high levels of uncertainty
and the possibility of causing irreversible harm on a global scale. When
investigating procedural principles of radioactive waste management policies by three types of precautionary approaches, the project will look at risks that stem from the displacement of politics in public consultations in relation to large infrastructural projects. The practices of the emerging era of public engagement tap into the current debates on democratic politics in political theory with the emergence of deliberative democracy (Bohman and Rehg, 1997; Dryzek, 2000; Gutmann and Thompson, 2009), and radical democracy (Laclau and Mouffe, 2001; Mouffe, 1999, 2000). Specific attention will be paid to the fragmentation of public along with technical and non-technical, local and national, site-specific and general issues, and the role of different political platforms (public exhibition events, consultation documents, and public engagement sessions) in the way in which the political is displaced from the arena of public inquiries to legal challenges and debates about boundaries and geographies.
Representing future generations in public participation procedures regarding the siting of a nuclear waste repository
Authors: Hamacher Lisa P.
Published: November 2021

Abstract. State decisions regarding a repository for high-level radioactive waste have an extraordinary intergenerational significance. The academic legal discussion has increasingly strengthened the status of future generations in constitutional law. In its recent decision on the German Climate Protection Act, the Federal Constitutional Court equally emphasised that state actors have an obligation to protect future generations. Fundamental rights of future generations thus have an anticipated effect in the present. In general, the legislator is free to choose the appropriate means to protect these rights. The interests of future generations may be promoted by substantive or procedural law. The German Site Selection Act (StandAG), however, makes use of procedural protections to a significant extent. Including the interests of future generations in the existing public participation procedures and participation bodies is, therefore, crucial for the effective protection of future generations. The presentation examines to which extent the current legal framework for the site selection for a high-level radioactive waste repository in Germany enables an effective representation of the future generations' interests. Existing publications (Appel, 2005; Rose, 2018; Kloepfer, 1993) name various characteristics of effective “intergenerational institutions”. Accordingly, these institutions should be independent, exist long-term, serve future interests solely or primarily, and have strong rights vis-à-vis decision-makers; however, German constitutional law, namely the principle of democracy, limits the design of such institutions. Not all of the abovementioned characteristics can be combined. Nevertheless, the constitution enables means to include and promote the interests of future generations in decision-making procedures, which are not fully exploited by the German Site Selection Act. The participation procedure includes several groups which could promote intergenerationally just decisions, namely environmental associations, the public and representatives of the “young generation”; however, none of these stakeholders are “intergenerational institutions” in the abovementioned sense. Subsequently, the presentation proposes various reforms: improving the sustainability impact assessment during the legislative procedure, the implementation of an “intergenerational impact assessment” and an ombudsperson for future concerns, who could be affiliated with the National Citizens' Oversight Committee (Nationales Begleitgremium).
