Use of threshold parameter variation for tropical cyclone tracking
Authors: Enz Bernhard M. , Engelmann Jan P. , Lohmann Ulrike
Published: September 2023

Abstract. Assessing the capacity of numerical models to produce viable tropical cyclones, as well as assessing the climatological behavior of simulated tropical cyclones, requires an objective tracking method. These make use of parameter thresholds to determine whether a detected feature, such as a vorticity maximum or a warm core, is strong enough to indicate a tropical cyclone. The choice of parameter thresholds is generally subjective.
This study proposes and assesses the parallel use of many threshold parameter combinations, combining a number of weaker and stronger values. The tracking algorithm succeeds in tracking tropical cyclones within the model data, beginning at their aggregation stage or shortly thereafter and ending when they interact strongly with extratropical flow and transition into extratropical cyclones or when their warm core decays.
The sensitivity of accumulated cyclone energy to tracking errors is assessed. Tracking errors include the faulty initial detection and termination of valid tropical cyclones and systems falsely identified as tropical cyclones. They are found to not significantly impact the accumulated cyclone energy. Thus, the tracking algorithm produces an adequate estimate of the accumulated cyclone energy within the underlying data.

Published: September 2023

Abstract. Cryogenic magic angle spinning (MAS) is a standard technique utilized for dynamic nuclear polarization (DNP) in solid-state nuclear magnetic resonance (NMR). Here we describe the optimization and implementation of a stator for cryogenic MAS with 9.5 mm diameter spherical rotors, allowing for DNP experiments on large sample volumes. Designs of the stator and rotor for cryogenic MAS build on recent advancements of MAS spheres and take a step further to incorporate sample insert and eject and a temperature-independent spinning stability of ±1 Hz. At a field of 7 T and spinning at 2.0 kHz with a sample temperature of 105–107 K, DNP enhancements of 256 and 200 were observed for 124 and 223 µL sample volumes, respectively, each consisting of 4 M 13C, 15N-labeled urea and 20 mM AMUPol in a glycerol–water glassy matrix.
Open-source Python library for modeling coupled thermo-hydro-mechanical (THM) processes
Authors: Rücker Carsten
Published: September 2023

Abstract. The interactions between temperature, fluids, and mechanical properties in a repository system are essentially described scientifically by coupled thermo-hydro-mechanical (THM) processes. THM modeling, i.e., the prediction of the behavior of materials under different conditions, is the fundamental numerical tool here. The confident handling and deep understanding of numerical computation methods is thus the prerequisite for performing and evaluating preliminary safety analyses in the site selection process. At the Federal Office for the Safety of Nuclear Waste Management (BASE), a
software library for the simulation of coupled THM processes is currently
being developed. The main goal of the in-house development is an open-source toolbox in the scripting language Python and is motivated by several long-term sub-goals:
targeted development of expertise within BASE regarding numerical modeling of safety-relevant aspects in the long-term safety analyses; diversification of the testing capabilities regarding the preliminary safety investigations by means of an in-house, independent modeling software; foundation of a library of known benchmarks and evaluation examples for the comparison of different software tools; documentation and processing of basic THM scenarios for internal or, if necessary, public technical training.
The focus of this development is on creating a toolbox that is easy to use
and at the same time highly flexible. The main methodical aspects are as follows:
building a new library based on the pyGIMLi pre- and postprocessing framework (Rücker et al., 2017); creating a finite-element reference implementation in the Python scripting language for maximal transparency; creating an easy-to-use interface to the solution of the weak formulation for the finite-element theory with expressions of a symbolic manner allowing maximal flexibility; defining an interface to allow for the integration of alternative, third-party high-performance libraries; creating a collection of Jupyter notebooks of well-documented test cases and benchmarks.
Choosing the open-source approach ensures the best possible transparency and, in the long term, also allows the provision of appropriately quality-assured and documented simulation tools to the public. The presented poster shows the current development status of the software library and the currently implemented quality assurance concepts and gives an outline of the potential applications of the library.
Two-phase reactive transport modeling of heterogeneous gas production in a low- and intermediate-level waste repository
Authors: Vehling Falko , Shao Haibing
Published: September 2023

Abstract. The widely proposed approach to dispose of low- and intermediate-level radioactive waste is to store it in a deep underground repository with multiple barriers. A typical gallery is filled with concrete containers accommodating cemented steel drums of waste. Inside a container, different gases may be produced by (bio)chemical reactions, which include pH-dependent anoxic corrosion of metals and the degradation of organic matter. Both reactions consume water and may lead to pressure buildup and transport of gas, both within and around the repository. In order to investigate the controlling factors of this gas production
process, a coupled reactive transport model of component-based two-phase flow in the OpenGeoSys framework is adopted here. The numerical study of Huang et
al. (2021) has shown that a realistic internal structure of a waste package, including the heterogeneous distribution of materials with different chemical and hydrological properties, and the exchange of mass at the boundaries are key factors that determine the evolution of the waste
package. Based on the study of Huang et al. (2021), the geometric configuration of the model has been further extended to reflect the various
conditions of a multi-container disposal in a gallery. In a two-dimensional
setup several model scenarios have been designed and simulated to study the
change in gas production rate over time in relation to water availability in various geological and waste storage setups. In this presentation, we show simulation results covering the geochemical
evolution of a waste package over 500 years. It is found that the initial
water content in the waste compartment only controls the gas production rate
for the first 40 to 60 years. The early pressure buildup and gas release
rates are largely controlled by several critical parameters, including the permeability of cement material and water availability at the boundary. The
sensitivity of these parameters is currently being investigated in detail.
Panel: “novel” nuclear reactors as an alternative disposal option
Authors: Englert Matthias , Frieß Friederike
Published: September 2023

Abstract. States and private industries are researching and developing reactor
concepts that are not based on the current light- or heavy-water-cooled
reactor technology. One important aspect of these so called novel or
advanced nuclear reactor designs, both large gigawatt types and small
modular reactors, is their potential for radioactive waste management. The
prospects for their development and industrial use also largely depend on
possible improvements to reactor safety, on the proliferation resistance of
the fuel cycle and on the economics of those reactor concepts. The panelists will discuss opportunities and impediments to the implementation and use of advanced reactor concepts and their fuel cycles, as well as their use as an alternative disposal option. The discussion will be open for the audience to participate. Regarding the method, a moderated panel discussion with four panelists is planned. First, after a short introduction by the moderator, the panelists will be given the opportunity to briefly present their view on important advantages and disadvantages of new reactors as a waste disposal option for about 20 min total. The focus should be on the involved fuel cycle (partitioning and transmutation); the state of science and technology of reactors for waste management, reprocessing and fuel fabrication; the impact of reactors on the quantity and composition of nuclear waste; and the possible deployment scenarios focusing on nuclear waste management. The need to use reactors for this alternative disposal option is a controversial issue in light of differing views on the use of nuclear energy nationally and internationally. We plan to invite a heterogeneous panel with expertise in reactor-based nuclear waste management, nuclear safety and security; the state of science and technology of advanced nuclear reactors (technology readiness level); and nuclear power economics. Ideally this panel will express differing views on the use of nuclear power as the panel's goal is explicitly to engage in an interactive discussion with the audience.
Experimental investigations with neutron radiography of hydrogen effects by elastic stresses on cladding tubes under conditions similar to interim dry storage
Authors: Weick Sarah , Grosse Mirco , Roessger Conrado , Steinbrueck Martin
Published: September 2023

Abstract. During operation in light-water reactors, Zircaloy
cladding tubes take up hydrogen that precipitates under specific
temperature–pressure conditions after operation in the form of zirconium
hydrides. These zirconium hydrides have a detrimental effect on the
mechanical stability of the cladding tubes. The conditions for their
formation and their orientation need to be forecasted in order to determine
that the spent nuclear fuel remains shielded during interim dry storage.
Internal and external stresses that affect the cladding tubes throughout
their slow cooling process during interim dry storage may worsen and
accelerate the cladding tubes' embrittlement with regard to possible
reorientation processes of zirconium hydrides. Generally, hydrogen in solid
solution follows gradients in temperature, concentration, and stress.
Consequently, hydrogen moves from higher to lower temperatures and from
lower to higher stresses due to the thermodynamically more favourable
conditions. In order to investigate elastic stress conditions similar to those during
interim dry storage of hydrogenated cladding tubes, a modified mobile
tensile testing machine was designed to elongate zirconium samples under
defined temperatures of up to 500 ∘C. During the experiments,
hydrogen movements within the samples are monitored by in situ neutron
radiography. Because of the very low neutron cross section of zirconium, the
metal is nearly invisible for neutrons, and the contrarily behaving hydrogen
that scatters neutrons strongly appears as dark contrast in neutron images.
Due to the sample's different cross section profile, the tensile stress
created by the tensile testing machine is amplified and thus should lead to
visible hydrogen movements. This paper describes neutron radiography experiments under different
temperature–time conditions with hydrogenated tensile zirconium samples that
simulate stress conditions of cladding tubes during interim dry storage.
Biosphere modelling in the calculation basis for dose assessment for a final disposal of high-level radioactive waste
Authors: Diener Alexander , Steiner Martin
Published: September 2023

Abstract. The government of Germany decided to isolate high-level radioactive waste
(HLW) in deep geological formations. Such a site should guarantee the highest
possible level of safety over a period of 1×106 years. The Federal
Ministry for the Environment, Nature Conservation, Nuclear Safety and
Consumer Protection (BMUV) asked the Federal Office for the Safety of
Nuclear Waste Management (BASE) and the Federal Office for Radiation
Protection (BfS) to develop a directive for dose assessment for a final
disposal of HLW, which has to be used for the site
selection process by the Federal Company for Radioactive Waste Disposal (BGE mbH), the operator of the future HLW repository. This regulation contains detailed provisions for the gas-bound and
water-bound radionuclide transport in the geosphere and biosphere and for
the dose estimation of the public. It is built upon established concepts in
radioecology and dosimetry. The comprehensive set of instructions is a toolbox for the dose estimation of a fictive representative person, one of the
indicators of the safety of the repository. Modelling of the biosphere over
1×106 years is impossible because natural processes and human activities affect the evolution of the biosphere in an unpredictable way. In addition, human habits like the way of life and agricultural practices cannot be predicted even for only hundreds of years. Therefore, it was laid down in another German regulation that the current human habits have to be assumed over the period under consideration. Existing models and parameters of current German regulations for public dose calculations have been adjusted to the specific conditions of a final repository and complemented where necessary. The challenge of how to take into account the future climate and its implications on the biosphere was solved by using reference biospheres covering all possible evolutions of the biosphere including climate transitions. The application of reference biospheres to cover climate changes is a common approach in comparable safety analyses. Germany favours the enveloping approach described above that implicitly comprises all possible climatic conditions and the corresponding evolutions of the
biosphere. The decisions on how to deal with the unknown future were the
results of discussions between BMUV, BASE, and BfS. To ensure transparency and participation in the site selection of the
HLW repository, the draft regulation was presented to the public, stakeholders, and the scientific community, providing the opportunity to
comment on every part of the content. This consultation process and an
expert workshop were the basis of the revision of the draft regulation. The
final regulation was published at the end of 2022. The participation process helped
to improve the document and to achieve a broader public acceptance. BASE and
BfS are currently working on a comprehensive explanatory text to address all
of the several hundreds of comments in detail.
Intra- vs. intergenerational justice tradeoffs in nuclear waste storage (W01)
Authors: Seidl Roman , Drögemüller Cord , Sierra Rosa
Published: September 2023

Abstract. We propose a workshop in two parts (approx. 90 min each) to discuss (i)
general dilemmas due to the long time range until an operable solution for
the waste problem is found and (ii) an ethics-inspired discussion on the
extra burden for communities hosting interim storage sites (based on
empirical data). In the first part, we highlight the twofold responsibility concerning the current generation's decision-making perspective for present and future generations. According to our survey data and a debate with citizens, we see the need to discuss the respective weighing of directly affected generations during the next few decades (until the repository's closure, which affects about four to five generations) compared to the justice for (five+) future generations in the following decades and centuries (see the figure in the Supplement). Questions are, for instance, is discounting the ethical relevance of future generations justified, necessary or forbidden? In the second part, we explore the consequences of the delayed final storage in Germany on the current interim storage sites. Following conversations with citizens (in Brokdorf, October 2022, and in Lubmin, March/April 2023) we investigate the tradeoffs between guaranteeing the safety in these sites and developing and implementing new concepts for long-term storage at these or new sites before commencing with final storage. In terms of safety and fairness, invasive monitoring of casks or storage in a new centralized interim repository would be welcomed by some. However, both possible measures conflict with long-term practices (e.g., approving licenses for several decades or the long-term planning for the final repository). Important questions to be discussed are, among others, how much time may current generations take to identify the most suitable site? How can addressing all three time horizons specified in the Site Selection Act help to contextualize delays in the initial steps? What are the risks and opportunities associated with delayed deep geological disposal (economic, social, political, etc.)? To what extent may intragenerational (current generations) justice discount for generations in
the far future? How can the prolongation of interim storage be justified? We propose a specific format during the workshop in which participants work in small groups using the rich picture methodology (https://naturwissenschaften.ch/co-producing-knowledge-explained/methods/method_factsheets/rich_picture, last access: 12 June 2023). This format is suitable for work in small groups to visualize (consensus or divergent views on) complex problems, structures and interrelationships between agents. The results from the small groups are then presented and discussed in the plenary. The respective answers to the key questions may provide possible practice-oriented results for responsible decision-makers (e.g., at BASE Bundesamt für die Sicherheit der nuklearen Entsorgung (Federal Office For The Safety Of Nuclear Waste Management)).
Advanced analysis of ultrasonic investigations at sealing structures
Authors: Lay Vera , Büttner Christoph , Buske Stefan , Niederleithinger Ernst
Published: September 2023

Abstract. Engineering barrier systems are a crucial part of the safe underground disposal of radioactive waste, particularly with salt as a host rock. Sealing structures made of tailored concrete are being tested at various sites in Germany. To characterise the material properties of the concrete and potentially also the bonding to the host rock as part of the necessary subsurface structures, we apply non-destructive testing, making use of advanced geophysical imaging methods. Ultrasonic investigations have been carried out at underground concrete
structures in the Teutschenthal mine in Germany. Here, we show results from
two distinct constructions produced in a shotcrete procedure. Our goal is to analyse the performance of ultrasonics to be used as quality assurance for sealing structures made from shotcrete. First, a ∼10 m long shotcrete structure is investigated with the help of a unique large aperture ultrasonic system (LAUS), allowing for depth penetration of >9 m. We perform measurements at the front and from the side of the construction. Second, we obtain results from a 1 m thick shotcrete body containing several artificial defects (width up to 8 cm). Ultrasonic testing data were acquired using a commercial multi-static device. Additionally, a new device measuring with 3D mode instead of line mode is applied, and preliminary results will be shown. Generally, the acquired ultrasonic data are analysed by a synthetic
aperture focusing technique that is commonly applied in non-destructive
testing. As a result, reflectors in the analysed shotcrete structures are
imaged. Individual reflections from internal features and particularly the
opposite wall are identified. An unexpected delamination wider than 30 cm is clearly imaged and later verified by boreholes. Thus, the method is – in general – suitable to serve as a quality measure. However, particularly the small and deep artificial defects can hardly be identified in the resulting images. Thus, we use advanced geophysical imaging methods to further enhance the quality of the obtained images. The recorded ultrasonic energy is focused on the physically reflective origin in the analysed volume. First results clearly show that we successfully improve the image quality regarding noise level and artefacts and hence facilitate the detection of objects. Therefore, we present a valuable experiment under realistic conditions for underground sealing structures made from shotcrete, where the locations of artificial reflectors are partly known. This experiment serves as a unique basis to analyse the performance of advanced analysis methods to obtain high-quality images of the structure's interior. Hence, the developed ultrasonic testing and analysis schemes can serve as a part of quality assurance that will help to enable safe sealing structures for nuclear waste disposal.

Abstract. Mesoscale convective systems (MCSs) are frequently observed over southern West Africa (SWA) throughout most of the year. These MCS events are the dominant rain-bearing systems, contributing over 50 % of annual rainfall over SWA. However, it has not yet been identified what variations in typical large-scale environments of the seasonal cycle of the West African monsoon may favour MCS occurrence in this region. Here, nine distinct synoptic states are identified and are further associated with being a synoptic-circulation type of either
a dry, transition, or monsoon season using self-organizing maps (SOMs) with inputs from reanalysis data. We identified a
pronounced annual cycle of MCS numbers with frequency peaks in April and
October that can be associated with the start of rainfall during the major
rainy season and the maximum rainfall for the minor rainy season across SWA,
respectively. Comparing daily MCS frequencies, MCSs are most likely to
develop during transition conditions featuring a northward-displaced
moisture anomaly (2.8 MCSs per day), which can be linked to strengthened
low-level westerlies. Considering that these transition conditions occur
predominantly during the pre- and post-monsoon period, these patterns may in
some cases be representative of monsoon onset conditions or a delayed
monsoon retreat. On the other hand, under monsoon conditions, we observe
weakened low-level south-westerlies during MCS days, which reduce moisture
content over the Sahel but introduce more moisture over the coast. Finally,
we find a majority of MCS-day synoptic states exhibiting positive zonal wind
shear anomalies. Seasons with the strongest zonal wind shear anomalies are
associated with the strongest low-level temperature anomalies to the north
of SWA, highlighting that a warmer Sahel can promote MCS-favourable
conditions in SWA. Overall, the SOM-identified synoptic states converge
towards high-moisture and high-shear conditions on MCS days in SWA, where
the frequency at which these conditions occur depends on the synoptic state.
Going Beyond BEM with BEM: an Insight into Dynamic Inflow Effects on Floating Wind Turbines
Authors: Papi Francesco , Jonkman Jason , Robertson Amy , Bianchini Alessandro
Published: September 2023

Abstract. Blade Element Momentum (BEM) theory is the backbone of many industry-standard wind turbine aerodynamic models. To be applied to a broader set of engineering problems, BEM models have been extended since their inception and now include several empirical corrections. These models have benefitted from decades of development and refinement and have been extensively used and validated, proving their adequacy in predicting aerodynamic forces of horizontal axis wind turbine rotors in most scenarios. However, the analysis of Floating Offshore Wind Turbines (FOWTs) introduces new sets of challenges, especially if new-generation large and flexible machines are considered. In fact, due to the combined action of wind and waves and their interaction with the turbine structure and control system, these machines are subject to unsteady motion, and thus unsteady inflow on the wind turbine’s blades, which could put BEM models to the test. Consensus is not present yet on the accuracy limits of BEM in these conditions. This study contributes to the ongoing research on the topic by systematically comparing four different aerodynamic models, ranging from BEM to Computational Fluid Dynamics (CFD), in an attempt to shed light on the unsteady aerodynamic phenomena that are at stake in FOWTs and whether BEM is able to model them appropriately. Simulations are performed on the UNAFLOW 1:75 scale rotor during imposed harmonic surge and pitch motion. Experimental results are available for these conditions and are used for baseline validation. The rotor is analysed both in rated operating conditions and in low wind speeds, where unsteady aerodynamic effects are expected to be more pronounced. Results show how BEM, despite its simplicity, if augmented with a dynamic inflow model, is able to adequately model the aerodynamics of FOWTs in most conditions.
UVLM-based mesh generator intended for onshore and offshore wind farms
Authors: Roccia Bruno Antonio , Ceballos Luis Ramón , Verstraete Marcos Leonardo , Gebhardt Cristian Guillermo
Published: September 2023

Abstract. In the last decades, the unsteady vortex-lattice method (UVLM) has gained a lot of acceptance to study large onshore/offshore wind turbines (WTs). Furthermore, and due to the development of more powerful computers, parallelization strategies and algorithms like the fast multipole method, it is possible to use vortex-based methods to analyze and simulate wind farms (WFs). However, UVLM-based solvers require structured meshes, which are generally very tedious to build using classical mesh generators, such as those utilized in the context of finite element methods (FEMs). Wind farm meshing is further complicated by the large number of design parameters associated with the wind turbine (pre-cone angle, tilt angle, blade shape, etc.), farm layout, modeling of the terrain topography (for onshore WFs), and modeling of the sea level surface (for offshore WFs), which makes the use of FEM-oriented meshing tools almost inapplicable. In the literature there is a total absence of meshing tools when it comes to building aerodynamic grids of WTs and WFs to be used along with UVLM-based solvers. Therefore, in this work, we present a detailed description of the geometric modeling and computational implementation of an interactive UVLM-oriented mesh generator, named UVLMeshGen, developed entirely in Matlab® and easily adaptable to GNU OCTAVE, for wind turbines and onshore/offshore wind farms. The meshing tool developed here consists of: i) a geometric processor in charge of designing and discretizing an entire wind farm; and ii) an independent module in charge of computing the kinematics for the entire WF. The output data provided by the UVLMeshGen consist of nodal coordinates and connectivity arrays, making it especially attractive and useful to be used by other flow potential solvers using: doublets, sources and sinks, or dipoles, among others. The work is completed by providing a series of aerodynamic results related to WTs and WFs to show the capabilities of the mesh generator, without going into detailed discussions of wind turbine aerodynamics, which are not the focus of this paper. The meshing tool developed here is freely available under a Creative Commons Attribution 4.0 International License Roccia (2023).

Published: September 2023

Footstrike pattern has received increased attention within the running community because there is a common belief that forefoot strike running (FFS) is more advantageous (i.e., improve performance and reduce running injuries) than rearfoot strike running (RFS) in distance running. Literature reports suggest greater knee joint flexion magnitude and initial knee angle during stance in FFS compared with RFS running We examined the EMG activation of the triceps surae muscles during an acute transition from RFS to FFS strike. We tested the hypothesis that due to larger knee flexion in FFS the gastrocnemius muscles possibly decrease their EMG activity because muscle fascicles operate under unfavorable conditions. Fourteen competitive healthy middle- and long-distance runners who were habitual RFS runners ran on a treadmill at three speeds: 12, 14, and 16 km·h-1. Each running speed was performed with both FFS and RFS patterns. Lower limb kinematics in the sagittal plane and normalized electromyography (EMG) activity of medial gastrocnemius proximal, middle and distal regions, lateral gastrocnemius and soleus muscles were compared between footstrike patterns and running speeds across the stride cycle. Contrary to our expectations, the knee joint range of motion was similar in FFS and RFS running. However, the sagittal plane ankle joint motion was greater (p < 0.01) while running with FFS, resulting in a significantly greater muscle-tendon unit lengthening (p < 0.01) in FFS compared with RFS running. In addition, medial and lateral gastrocnemius showed higher EMG activity in FFS compared with RFS running in the late swing and early stance but only for a small percentage of the stride cycle. However, strike patterns and running speed failed to induce region-specific activation differences within the medial gastrocnemius muscle. Overall, well-trained RFS runners are able to change to FFS running by altering only the ankle joint kinematics without remarkably changing the EMG activity pattern.

Эпизоотический лимфангит, это изнуряющее грибковое заболевание, вызываемое изолятом Histoplasma farciminosum, которое в основном встречается у лошадей. Его наиболее распространенной формой является язвенный, гнойный, однако у некоторых животных могут развиться поражения других органов, особенно дыхательные пути или глаз. Лечение не проводят. Коммерческих вакцин против эпизоотического лимфангита не существует, хотя некоторые сообщения свидетельствуют о том, что живые и инактивированные вакцины были испытаны (и, возможно, использованы) в некоторых эндемичных регионах (например, в нашей республике и Китае) и оказались многообещающими.

Эффективность вакцин, вызывающих стойкий напряженный иммунитет и сокращения сроков создания защитного иммунитета, зависит не только от количества и качества антигена, но и от подобранных адъювантов способных усиливать процесс иммунизации.

В связи с этим одной из следующих целей исследования являлся подбор наиболее оптимального адъюванта для инактивированной вакцины против лимфангоита лошадей, повышающий специфический иммунный ответ.

На основе анализа данных зарубежной литературы, а также собственных результатов, полученных на основе ранее проведенных экспериментов в качестве наиболее перспективного адъюванта нами выбран адъювант на водной основе, содержащий дисперсию высокомолекулярного полиакрилового полимера  Montanide Gel 01 PR (Seppic, Франция), отличающийся высокой безопасностью, эффективностью, простотой использования и экономической целесообразносью.
Development and validation of a work-related risk score for upper-extremity musculoskeletal disorders in a French working population
Authors: Rapicault Clémence , Roquelaure Yves , Bodin Julie , Fouquet Natacha , Bertrais Sandrine
Published: September 2023

OBJECTIVES: The aim was to develop an easy-to-use risk score based on occupational factors and to validate its performance to identify workers either having (diagnostic setting) or developing (prognostic setting) upper-extremity musculoskeletal disorders (UEMSD).

METHODS: This study relied on data from the Cosali prospective cohort conducted in a French working population. Diagnostic status for six UEMSD at inclusion and at follow-up was assessed by a standardized clinical examination. Data on occupational factors were collected through a self-administered questionnaire completed before the clinical examination at inclusion. The risk score was derived from a prediction model developed on data of 2,468 workers included in 2002-2003, and the validation sample is composed of 1,051 workers included later in 2004-2005. The prognostic performance of the risk score was assessed in workers without UEMSD at baseline.

RESULTS: A total of 13% and 12% of workers had a UEMSD at inclusion in the development and validation sample. The developed risk score includes physical, organizational and psychosocial factors at work. In the validation sample, this score had acceptable performance for identifying workers having or not UEMSD at baseline (AUC: 0.60 [95% CI 0.57 to 0.63]), in particular the negative predictive value was high (89%-90%). The baseline risk score showed similar performance for predicting incident UEMSD at follow-up examination.

CONCLUSION: This score can be useful as a first-line risk assessment tool, especially for excluding the low-risk work situations from further intervention by an ergonomist. Further validation studies are needed to determine its performance among various working populations.
Human-AI Collaboration: Exploring interfaces for interactive Machine Learning
Authors: Et al. Gonesh Chandra Saha
Published: September 2023

Human-AI collaboration embodies the idea that AI systems and humans work together synergistically, leveraging each other's strengths to achieve more than what either can do in isolation. It's a shift from the traditional notion of AI as a replacement for human labour to a partnership where AI augments human capabilities. This collaboration is founded on trust, where humans rely on AI for data-driven insights, and AI relies on human expertise for nuanced decision-making. In the ever-evolving landscape of technology, one of the most profound transformations is the collaboration between humans and artificial intelligence (AI). This collaboration is further facilitated and enhanced through the interfaces of machine learning (ML), where humans interact with AI algorithms to achieve collective goals. As artificial intelligence (AI) continues to advance, the synergy between humans and machines becomes increasingly significant. This paper delves into the evolving landscape of Human-AI Collaboration, with a particular focus on interactive Machine Learning (iML) interfaces. In a world where AI systems permeate numerous facets of society, understanding how humans can effectively collaborate with AI through intuitive interfaces is paramount. This research comprehensively explores the pivotal role of user interfaces in facilitating collaborative machine learning. It encompasses an analysis of existing iML interfaces, user experience evaluations, and the proposition of innovative design principles to enhance the effectiveness of AI as a collaborative tool. This study contributes to advancing our understanding of harnessing AI's potential to empower users in various domains.

This study aims to assess the effect of institutional strategies on the development of employability skills, mediated by graduate capital forms among business education students in some selected public and transnational universities in Ghana. Institutional theory underpinned this study. The institutional strategy constructs of curriculum design, extracurricular activities, work-integrated learning, internship and job placement, university engagement with industries, career centers, and student engagement with employability development opportunities predicted the dependent variable graduate employability with the mediating variables. On a sample of 1280 survey participants, structural equation modelling was used. The findings showed that all of the constructs included in institutional strategies had a favourable, significant impact on the growth of graduate employability abilities. The development of social, cultural, and psychological capital forms under the mediating variable was supported to have an indirect influence or partial mediation between institutional tactics and the development of graduate employability abilities. The findings recommend public universities should be more proactive in promoting the employability agenda by assisting students in building their employability skills in a digitalized world. Again, regulators and decision-makers like the Ministry of Education (MoE) and the Ghana Tertiary Education Commission (GTEC) should reconsider making the development of employability skills in the academic fields of undergraduate education that reflect and merit the rapidly changing skill requirements of contemporary and digitalised work environments, especially curriculum design.

Published: September 2023

В статье рассматриваются теоретические основы процесса инкультурации личности в процессе формирования личности. Нами изучены научные исследования по теме инкультурации, обозначены основные подходы к изучению и результаты работ. В связи с активной виртуализацией общества мы полагаем, что изменения в социальной и культурной сферах повлияют также на процесс освоения индивидуумом культурных ценностей и формирование личности в дальнейшем. Таким образом, мы делаем вывод, что в настоящее время можно утверждать о традиционных формах и инновационных. В нашей работе мы описали процесс инкультурации личности в реальном мире, что относим к традиционной форме. Обозначены особенности основных фаз инкультурации и взаимоотношения человека и культуры на каждом из них. Следствием виртуализации культуры стало появление интернет-культуры, которая обозначена с точки зрения формирования культуры вторичной, абстрактной, намечены основные черты. Таким образом, в процессе инкультурации индивидуум проходит не только процесс освоения культуры реального мира, но и виртуального, в связи с чем выдвинуто предположение об инновационном подходе.

The article deals with the theoretical foundations of the process of enculturation of personality in the process of formation of personality. The author believes that due to the active virtualization of society, changes in the social and cultural sphere will also affect the process of individual's cultural values and identity formation in the future. Thus, at present there are traditional forms as well as innovative ones. The author uses the traditional form to describe the process of enculturation of the individual in the real world. The features of the main phases of enculturation and the relationship between man and culture at each of them are outlined. A consequence of the virtualization of culture was the emergence of Internet culture, which is outlined in terms of the formation of secondary, abstract culture. In conclusion, in the process of enculturation an individual goes through not only the process of mastering the culture of the real world, but also the virtual one; assumption of innovative approach is put forward.

Статья посвящена истории России XVIII в., периоду правления выдающегося реформатора – Петра I, интерес к деяниям которого не ослабевает. Рассматриваются вопросы привлечения иностранных мастеров на русскую службу, особенности заключения договора, условия службы и увольнения с должности, размер заработка и другое. Отмечается, что наряду с посредниками, близкими к царю, дипломатами или специально посланными в Западную Европу агентами, приглашением в Россию мастеров занимались лица менее значимые и известные. Источниковую базу составили документы, связанные с деятельностью иностранцев в России. Важную роль сыграли различные дневники и мемуары участников событий. В России уже в XVIII в. большое внимание уделялось правовым вопросам оформления отношений с иностранным мастером. Учитывались не только пожелания самого специалиста, но и выгоды нанимающей стороны. Контракты с иноземцами говорят о достаточно высокой правовой культуре, присущей Российской империи в тот период. Советские и российские исследователи обращались к избранной нами теме, освещая общие аспекты привлечения иностранцев для службы в России. Ряд историков рассматривали вопросы юридического статуса иностранцев из отдельных стран, в частности Англии, Франции, Германии.

The article discusses the issues of attracting foreign masters to the Russian service in the XVIII century, the specifics of concluding a contract, the conditions of service and dismissal from office, the amount of earnings and more. It is noted that along with intermediaries close to the tsar, diplomats or agents specially sent to Western Europe, less significant and well-known persons were engaged in inviting masters to Russia. Already in the XVIII century, much attention was paid to the legal issues of registration of relations with a foreign master. Not only the wishes of the specialist himself were taken into account, but also the benefits of the hiring party. Contracts with foreigners speak of a fairly high legal culture inherent in the Russian Empire at that time. Soviet and Russian researchers explored the chosen topic, focusing on the general aspects of attracting foreigners to serve in Russia. A number of historians considered the legal status of foreigners from certain countries, in particular England, France and Germany.
