A tracial characterization of Furstenberg’s conjecture
Authors: Bruce Chris , Scarparo Eduardo 
Published: September 2023

AbstractWe investigate almost minimal actions of abelian groups and their crossed products. As an application, given multiplicatively independent integers p and q, we show that Furstenberg’s
$\times p,\times q$
conjecture holds if and only if the canonical trace is the only faithful extreme tracial state on the
$C^*$
-algebra of the group
$\mathbb {Z}[\frac {1}{pq}]\rtimes \mathbb {Z}^2$
. We also compute the primitive ideal space and K-theory of
$C^*(\mathbb {Z}[\frac {1}{pq}]\rtimes \mathbb {Z}^2)$

A Comparative Study of Synchronous and Asynchronous Online Discussions in Promoting Critical Thinking Skills
Authors: Bokase Martin 
Published: September 2023

The decision between synchronous and asynchronous online dialogues has major consequences for building critical thinking abilities among learners in the field of online education. A comparative analysis was performed in this study to determine the usefulness of different conversation formats in the context of cognitive development. The study used a quantitative technique to examine pre-test and post-test scores of individuals who participated in either synchronous or asynchronous talks. Qualitative insights were also collected via participant questionnaires and observation. The findings demonstrated that both conversation approaches had the ability to improve critical thinking abilities, however the outcomes differed slightly. The pre-test results showed that participants in both groups had comparable baseline cognitive skills. However, the post-test results favored the synchronous group, with a mean score of 82.15 against 79.32 in the asynchronous group. This contrast highlighted the significance of real-time engagement in allowing for instant analysis and critical evaluation. Congruent with earlier research, synchronous dialogues emerged as a venue for deep cognitive involvement, harmonizing with ideas of social presence and active participation. Asynchronous talks, on the other hand, provided flexibility by allowing learners to interact at their own speed, but with significantly reduced development. These findings have significance for educators, instructional designers, and institutions, directing the selection of discussion formats that are matched with intended pedagogical goals. The study adds to the conversation about online debates and critical thinking by giving a complete knowledge of their influence and emphasizing the importance of context in educational settings.
The Kano Model Assessment Framework for Soil Environmental Quality under Good Governance Doctrine of Bank Independence and Accountability for Code of Conduct towards Corporate Ethics
Authors: Llarena Zharama 
Published: September 2023

Purpose: Bank trading is basically observed in their traditional agreements of bargaining products and services. However, in terms of meeting and complying with global economic standards set by WTO to promote sustainable development known as doctrine of good governance, it is certain that corporate practices will be lacking explanatory tools for achieving corporate ethics as their culmination of bank independence and accountability to civil society. This paper aims to map the importance of bank independence and its accountability using Kano model assessment in addressing issues of concerns in trade-environmental problems under WTO economic standards.
Methodology: Soil environmental quality is a quantitative measurement of Kano developmental framework using positivistic paradigm towards legal scholarship defiance of corporate ethics for culmination reflection and plotting the behavior of corporate institutions to eradicate poverty line and promote the economic prosperity of their territory or jurisdiction by answering issues on environmental problems such as soil quality for advocacy of environmental protection under trade-environment conflicts of WTO as accountability to human society for achieving sustainable development following good governance doctrine.
Findings: Business law has a dynamic performance of both the behavior of the corporate and its environment through interactions of human society in their competition market. Innovation of products and corporate services must be integrated with good governance principles using the insufficiency of their code of conduct explanatory authority to enforce trade-environment agreements in achieving human rights of sustainable development in international and global economic standards. The realization of civil rights to sustainable development is reflected with the good governance principle.
Recommendations: The legal scholarship defiance of doctrinal research using positivistic paradigm of objective knowledge can be recommended to other corporate practices to advocate financial intelligence through active participation to environmental calls as political agendas as intended to lessen poverty towards integration to economic transparency and ecological protection. The plotting over time can be predicted towards comparison of constitutional rights of public welfare and safety.
Pueblo wichí y educación superior: una experiencia intercultural en la Universidad Nacional de Salta
Authors: Rodríguez Nuria Macarena , Di Pietro Noelia Daniela , Ossola María Macarena , Soriano Gonzalo Víctor Humberto 
Published: September 2023

El artículo se basa en una investigación incipiente acerca de la Diplomatura en Interpretación y Traducción Intercultural Wichí-Castellano para el Acceso a la Justicia. El objetivo de la pesquisa es comprender las experiencias de los estudiantes de la Diplomatura y cómo se relacionan con los modos en que se desarrolla esta política educativa institucional. La metodología sigue una lógica cualitativa, enmarcada en la Antropología de la Educación y la Pedagogía Crítica. Se trata de un estudio de caso que recupera aportes de la etnografía como enfoque. Esta experiencia resulta relevante por ser la primera carrera universitaria, en Argentina, destinada exclusivamente a miembros de un pueblo indígena que son bilingües (wichí-español). Además, se utilizan ambas lenguas para su dictado, que se desarrolla con docentes indígenas y no indígenas, lo cual cobra mayor relevancia por el valor identitario que tiene la lengua para el pueblo wichí. Se destaca, también, por el protagonismo de los wichí en la demanda, diseño y desarrollo de la Diplomatura, así como la participación de diferentes instituciones. Los primeros análisis en la investigación nos permitieron identificar esta experiencia como transformadora, dado que modifica las relaciones históricas de estos estudiantes con la educación formal, en sus trayectorias previas.
Evaluating the preparation of pre-service school-based agricultural education teachers in laboratory-based courses
Authors: Kevin Sanders  , Smalley Scott , Mark Hainline  
Published: September 2023

This study sought to examine laboratory-based instruction for pre-service school-based agricultural education (SBAE) teachers at various institutions across the nation. While research has indicated that laboratory-based instruction in SBAE programs is commonplace (Shoulders & Meyers, 2012), a myriad of literature has noted SBAE teachers are not adequately prepared to teach, manage, and facilitate learning activities in SBAE laboratories upon completing their teacher education programs (Burris et al., 2005; Hainline & Wells, 2019; Shoulders, 2012).
To better understand the current state of SBAE pre-service teacher training in laboratory instruction, we surveyed 33 agricultural education certifying institutions across the country. Many of these institutions indicated they required pre-service teachers to take two laboratory-based instruction courses in the areas of agricultural mechanics (96.9%) and welding metal fabrication livestock (83.9%). However, only 46.7% of the responding institutions required students to take a greenhouse management course, and 29% required pre-service teachers to take a meat science course. The findings of this study also highlight if the laboratory-based courses had a pedagogical component, and the teacher educators were asked to provide their perceptions for a need for expansion of instruction in each context. Recommendations for practice and further investigation were provided.
Quantitative rainfall analysis of the 2021 mid-July flood event in Belgium

Published: September 2023

Abstract. The exceptional flood of July 2021 in central Europe impacted Belgium severely. As rainfall was the triggering factor of this event, this study aims to characterize rainfall amounts in Belgium from 13 to 16 July 2021 based on two types of observational data. First, observations recorded by high-quality rain gauges operated by weather and hydrological services in Belgium have been compiled and quality checked. Second, a radar-based rainfall product has been improved to provide a reliable estimation of quantitative precipitation at high spatial and temporal resolutions over Belgium. Several analyses of these data are performed here to describe the spatial and temporal distribution of rainfall during the event. These analyses indicate that the rainfall accumulations during the event reached unprecedented levels over large areas. Accumulations over durations from 1 to 3 d significantly exceeded the 200-year return level in several places, with up to 90 % of exceedance over the 200-year return level for 2 and 3 d values locally in the Vesdre Basin. Such a record-breaking event needs to be documented as much as possible, and available observational data must be shared with the scientific community for further studies in hydrology, in urban planning and, more generally, in all multi-disciplinary studies aiming to identify and understand factors leading to such disaster. The corresponding rainfall data are therefore provided freely in a supplement (Journée et al., 2023; Goudenhoofdt et al., 2023).
Coastal and regional marine heatwaves and cold spells in the northeastern Atlantic

Published: September 2023

Abstract. The latest Intergovernmental Panel on Climate Change (IPCC) report describes an increase in the number and intensity of marine heatwaves (MHWs) and a decrease in marine cold spells (MCSs) in
the global ocean. However, these reported changes are not uniform on a regional to local basis, and it remains unknown if coastal areas follow the
open-ocean trends. Surface ocean temperature measurements collected by satellites (from 1982–2022) and 13 coastal buoys (from 1990–2022) are
analyzed in the northeastern Atlantic and three subregions: the English Channel, Bay of Brest and Bay of Biscay. The activity metric, combining the number
of events, intensity, duration and spatial extent, is used to evaluate the magnitude of these extreme events. The results from in situ and
satellite datasets for each of the studied regions are quite in agreement, although the satellite dataset underestimates the amplitude of activity
for both MHWs and MCSs. This supports the applicability of the method to both in situ and satellite data, albeit with caution on the amplitude of
these events. Also, this localized study in European coastal northeastern Atlantic water highlights that similar changes are being seen in coastal and
open oceans regarding extreme events of temperature, with MHWs being more frequent and longer and extending over larger areas, while the opposite is
seen for MCSs. These trends can be explained by changes in both the mean of and variance in sea-surface temperature. In addition, the pace of evolution
and dynamics of marine extreme events differ among the subregions. Among the three studied subregions, the English Channel is the region
experiencing the strongest increase in summer MHW activity over the last 4 decades. Summer MHWs were very active in the English Channel in 2022
due to long events, in the Bay of Biscay in 2018 due to intense events and in the Bay of Brest in 2017 due to a high occurrence of events. Winter
MCSs were the largest in 1987 and 1986 due to long and intense events in the English Channel. Finally, our findings suggest that at an interannual
timescale, the positive North Atlantic Oscillation favors the generation of strong summer MHWs in the northeastern Atlantic, while
low-pressure conditions over northern Europe and a high off the Iberian Peninsula in winter dominate for MCSs. A preliminary analysis of air–sea
heat fluxes suggests that, in this region, reduced cloud coverage is a key parameter for the generation of summer MHWs, while strong winds and
increased cloud coverage are important for the generation of winter MCSs.
Model-based performance assessment of repository-induced effects: contribution to the site-selection process in Switzerland
Authors: Li Chao , Zbinden Dominik , Hayek Mohamed , Hannon Michael J. , Papafotiou Alexandros , Marschall Paul 
Published: September 2023

Abstract. The procedure for selecting repository sites in Switzerland is specified in the Sectoral Plan for a deep geological repository (DGR), which consists of three stages. In the last Stage 3, three candidate siting regions, Jura Ost, Nördlich
Lägern and Zürich Nordost in northern Switzerland, were examined in detail. For each site, the performance of the geological barrier was
evaluated based on the characteristics at the time of repository closure
considering a certain degree of uncertainty associated with the exploration
and characterization of the geology as well as the long-term evolution of
the site. Furthermore, performance assessment includes an evaluation of the
safety-relevant repository-induced effects on the disposal system, such as
thermal, gas, chemical and mechanical (THMC) effects introduced by the interaction of the waste with the near field. A criterion-based indicator
approach was adopted to ensure a traceable implementation of the site-selection process. The complexity of the involved THMC processes calls for model-supported
workflows to reach a quantitative assessment of the barrier performance and
an adequate evaluation of the associated conceptual and parametric
uncertainties. The first task of the workflow was dedicated to the
elaboration of preliminary site-descriptive models for the proposed repository configurations at the candidate sites. Three-dimensional and
two-dimensional representations of entire repositories and individual
repository components were established and incorporated into the site-descriptive models to provide preliminary site-specific assessment models
for the evaluation of coupled THMC effects. The models accounted for the
entire life cycle of the repositories from construction to the post-closure phase. Safety-relevant indicators were developed to quantify the performance
of different repository configurations and to establish potential discriminators for the site selection. The workflow integrated deterministic
and probabilistic assessments on the repository and component scales. As a final step, the data acquired with the latest site investigations (i.e., new data from seismic and deep borehole campaigns) were integrated into the
existing models for the elaboration of the site-specific analyses. The
indicators were evaluated by integrating a wide range of information, including regional stress conditions, tectonic structures, stratigraphy, lithology,
mineralogy, and the impact from effects induced by the repository for the
entire spectrum of repository configurations. The spatial maps of indicators
depicting the impact from repository-induced effects were synthesized in the site-selection process as aggregated georeferenced performance measures to
evaluate the performance at each site with regards to the regulatory
criteria.
Bentonite buffer under high temperature: laboratory experiments and coupled process modeling

Published: September 2023

Abstract. Bentonite buffer in a geological repository will be
simultaneously heated from decaying radioactive waste and hydrated from the
surrounding host rock, triggering complex and coupled THMC
(thermal–hydrological–mechanical–chemical) processes. Understanding the THMC
behavior of bentonite-based engineered barrier system (EBS) is key to the evaluation and prediction of
its long-term performance. Studies on the THMC process have been focused on
conditions under 100 ∘C, as most design concepts impose a
thermal limit of 100 ∘C in bentonite. Recently, studies under
high-temperature conditions have been conducted to evaluate the possibility
of raising the thermal limit and expanding the data/knowledge base to
increase the confidence level. In this abstract, we present a series of
bench-scale laboratory experiments at high temperatures (up to
200 ∘C) and the corresponding modeling work. Two sets of
column tests were conducted, and each set consisted of two test columns: a
control column undergoing only hydration (non-heated) and an experiment
column experiencing both heating and hydration (heated). During the
experiment, frequent X-ray computed tomography (CT) images were collected to provide a 3D
visualization of the density distribution and present the spatiotemporal
evolution of (1) hydration/dehydration, (2) clay swelling/shrinkage, (3) displacement, and (4) mineral precipitation. The two sets of tests differ with respect to
several experimental conditions, such as bentonite type, compacted density
and water content, water chemistry, and hydration pressure, but the
important difference is that the first set used bentonite powder with a dry
density of 1.28 g cm−3, whereas the second set used granulated bentonite (mixture
of pellets and powder) with a dry density of 1.45–1.5 g cm−3. In both
sets of experiments, a comprehensive post-dismantling characterization of
bentonite samples was carried out after the column tests had been running for
1.5 years. Comparing non-heated and heated columns, the temperature gradient led
to lower degree of homogenization of bentonite after bentonite became fully
saturated; comparing the first and second sets, granulated and powdered
bentonite exhibited drastically different hydration behavior. A THM model
with a 2D axisymmetric grid system was used to interpret the data from the
first set of tests. The model considers the combined impact of saturation,
fluid pressure, and porosity change due to swelling/compression on the
spatiotemporal distribution of bulk density and movement of the thermocouple
modules. Observations from the tests help us understand the early
perturbation of bentonite buffer under high temperature, and data from these
tests improve the calibration of key constitutive hydrological and
mechanical models and, therefore, enhance the modeling capability with respect to
calculating the long-term evolution of bentonite buffer.
