description: Für die Modellierung des Hochfrequenzverhaltens paralleler Versorgungslagen in Leiterplatten wurde ein effizientes Ersatzschaltbild in [1] vorgestellt. Es basiert auf einer stabilen FosterDarstellung mit einer relativ geringen, gut abschätzbaren Anzahl von modalen Schwingkreisen und einem gekoppelten induktiven Netzwerk zur Konvergenzbeschleunigung. Zur Bestimmung der Schaltelemente für eine beliebig geformte Struktur müssen die Eigenfunktionen, Eigenwerte und die statischen Induktivitäten numerisch ermittelt werden. Zu diesem Zweck wurde zuerst eine auf einem homogenen gleichförmigen Netz basierende Finite-DifferenzenMethode (FDM) implementiert [1]. Um eine hinreichende Genauigkeit zu erreichen, muss die Struktur sehr fein diskretisiert werden. Speziell komplexe Geometrien benötigen einen hohen Modellierungsund Rechenaufwand. In diesem Beitrag stellen wir einen wesentlich effektiveren Finite-Elemente-Ansatz (FEM) vor, welcher auf einem Netz aus Dreieckselementen beruht und somit eine Modellierung mit erheblich weniger Aufwand gestattet. Zusätzlich wird dadurch eine gezielte lokale Netzverfeinerung ermöglicht, was besonders in der Nähe der kleinen kreisrunden Via-Ports von Vorteil ist. Die Ergebnisse werden durch Hochfrequenzmessungen und 3D-Vollwellensimulationen sowohl im Frequenzals auch im Zeitbereich validiert.

description: School counselors (SCs) are tasked with addressing the academic, career, and personal/social development of all students. As mental health issues experienced by school-aged children have increased, SCs have been unable to provide adequate mental health services. Because of barriers to receiving communitybased mental health services, school-based services are becoming increasingly necessary. In this article we propose that School-Based Mental Health Counselors (SBMHCs), specifically trained to work with schoolaged children and placed within a school setting, are appropriate for meeting students’ mental health needs. Although SBMHCs are not new to counseling, we make specific recommendations and suggestions for the training and practice of SBMHCs so that they can collaborate with SCs to meet the mental health needs of all students.

description: Primary Project (formerly known as Primary Mental Health Project) is one of the longest standing and wellestablished school-based preventative mental health interventions for addressing the social, emotional, behavioral, and learning needs of preschool through primary grade children. Existing now for over 60 years and building on its historical antecedents, this article describes the history, current state, and future implications of Primary Project. We discuss children’s mental health needs and the role of the school in addressing these needs. We present Primary Project’s current research efforts with a specific focus on University-community studies in Arkansas and Massachusetts. Implications for future research and school based counseling and policy and evaluation are addressed.

description: Cytochalasans are one type of PKS-NRPS secondary metabolites. The tailoring steps involved in cytochalasan biosynthesis are almost clear, but the formation of the isoindolone core is still mysterious. The ACE1 metabolite probably belongs to the cytochalasan family based on the biosynthetic gene cluster (BGC) analysis, even though the structure is not yet elucidated. Heterologous expression of ace1 (PKS-NRPS) and rap1 (trans-ER) in A. oryzae produced an unexpected alcohol, which is unlikely to undergo further Knoevenagel reaction. Therefore it is deduced to be a shunt metabolite during heterologous expression. To investigate the biosynthesis of the cytochalasan skeleton including reductive release, putative Knoevenagel condensation and Diels-Alder reaction, three model compounds mimicking the ACE1 metabolite precursor were designed, prepared and applied for in vitro assays. Model A was designed and synthesized for over-reduction investigation. In vitro assays confirmed that model A can be reduced to the corresponding primary alcohol by A. oryzae cell free extract. This indicates that the alcohol is a shunt metabolite and A. oryzae is not a suitable host for cytochalasan heterologous expression. Model B was designed and prepared to study Knoevenagel condensation. In vitro assays with model B suggested model B can possibly form pyrrolinone spontaneously in buffer, while pyrrolinone was converted rapidly to alcohols. However, no enzyme activity was observed. Besides, pyrrolinone tautomerism was further investigated by comparing tautomerized pyrrolinone and non-tautomerised pyrrolinone. From NMR and UV analysis, it is confirmed that pyrrolinones tautomerises and are no longer competitive for the following Diels-Alder reaction. Model C was designed for both Knoevenagel condensation and Diels-Alder reaction tests. In vitro Assays showed that pyrrolinone was formed spontaneously, further confirming the Knoevenagel condensation is spontaneous. But its corresponding pyrrolinone also tautomerised and is no longer suitable for the following Diels-Alder reaction.

description: This work presents an extension of graph-based SLAM methods to exploit the potential of 3D laser scans for loop detection. Every high-dimensional point cloud is replaced by a compact global descriptor, whereby a trained detector decides whether a loop exists. Searching for loops is performed locally in a variable space to consider the odometry drift. Since closing a wrong loop has fatal consequences, an extensive verification is performed before acceptance. The proposed algorithm is implemented as an extension of the widely used state-of-the-art library RTAB-Map, and several experiments show the improvement: During SLAM with a mobile service robot in changing indoor and outdoor campus environments, our approach improves RTABMap regarding total number of closed loops. Especially in the presence of significant environmental changes, which typically lead to failure, localization becomes possible by our extension. Experiments with a car in traffic (KITTI benchmark) show the general applicability of our approach. These results are comparable to the state-of-the-art LiDAR method LOAM.

description: The propagation of a wave-packet in a nonlinear disordered medium exhibits interesting dynamics. Here, we present an analysis based on the nonlinear Schrödinger equation (Gross-Pitaevskii equation). This problem is directly connected to experiments on expanding Bose gases and to studies of transverse localization in nonlinear optical media. In a nonlinear medium the energy of the wave-packet is stored both in the kinetic and potential parts, and details of its propagation are to a large extent determined by the transfer from one form of energy to the other. A theory describing the evolution of the wave-packet has been formulated in [G. Schwiete and A. Finkelstein, Phys. Rev. Lett. 104, 103904 (2010)] in terms of a nonlinear kinetic equation. In this paper, we present details of the derivation of the kinetic equation and of its analysis. As an important new ingredient we study interparticle-collisions induced by the nonlinearity and derive the corresponding collision integral. We restrict ourselves to the weakly nonlinear limit, for which disorder scattering is the dominant scattering mechanism. We find that in the special case of a white noise impurity potential the mean squared radius in a two-dimensional system scales linearly with t. This result has previously been obtained in the collisionless limit, but it also holds in the presence of collisions. Finally, we mention different mechanisms through which the nonlinearity may influence localization of the expanding wave-packet.

title: Physical Activity Perceptions and Associations with Markers of Health in Cancer Survivors: A Match-Funded PhD Project by Liverpool John Moores University and the Underground Training Station Foundation.

Publisher: name: Liverpool John Moores University
Year: 2022

description: Evidence suggests that regular physical activity (PA) and exercise can improve health and wellbeing following a cancer diagnosis and may help reduce cancer recurrence and mortality and prolong disease-free survival in cancer survivors. However, few cancer survivors are regularly active and many fail to meet the recommended PA guidelines. This is a major area of concern as for survivors to achieve the long-term health benefits associated with PA and exercise, they must be habitually active. The overall aim of this thesis was to explore PA and exercise participation in adult cancer survivors, with a specific focus on group-based PA and exercise. Study 1 explored cancer survivors’ perceptions of general PA and identified specific barriers and facilitators they experience specifically related to group-based activity. Qualitative methodology was employed and underpinned by the PRECEDE component of the PRECEDE-PROCEDE model. A unique finding from Study 1 was the group-based format of the exercise program being a key facilitator for PA and exercise participation. Study 2 evaluated the feasibility of a virtual home-based exercise intervention utilising the RE-AIM evaluation framework and explored participant experiences transitioning from a gym-based to home-based setting to exercise during the COVID-19 pandemic. A mixed-methods approach was employed to evaluate each dimension of the RE-AIM framework and additional qualitative methods were employed to explore participant experiences. High levels of acceptability and satisfaction (feasibility) were reported by participants, significant improvements in physical fitness and mental health were observed, and the group-based format and coach were reported as key facilitators for adherence to the intervention. Study 3 identified and critically reviewed the literature exploring the effect of home-based PA and exercise interventions on PA, physical fitness (PF), and quality of life (QoL) in cancer survivors. The effect of home-based PA and exercise interventions on PA, PF and QoL appeared complex. There was some evidence for the positive effects of home-based PA and exercise interventions on PA, PF and QoL in this population, particularly those with aerobic exercise components and additional support. Assessment tools used, and outcomes reported were variable, specifically for PA. Overall, there is a need for standardisation across studies in terms of assessment methods that will facilitate future reviews in this area.

description: We present a numerical study of the slip link model introduced by Likhtman for describing the dy- namics of dense polymer melts. After reviewing the technical aspects associated with the implemen- tation of the model, we extend previous work in several directions. The dependence of the relaxation modulus with the slip link density and the slip link stiffness is reported. Then the nonlinear rheolog- ical properties of the model, for a particular set of parameters, are explored. Finally, we introduce excluded volume interactions in a mean field such as manner in order to describe inhomogeneous systems, and we apply this description to a simple nanocomposite model. With this extension, the slip link model appears as a simple and generic model of a polymer melt, that can be used as an alternative to molecular dynamics for coarse grained simulations of complex polymeric systems.

description: Snake robots offer considerable potential for endoscopic interventions due to their ability to follow curvilinear paths. Telemanipulation is an open problem due to hyper-redundancy, as input devices only allow a specification of six degrees of freedom. Our work addresses this by presenting a unified telemanipulation strategy which enables follow-the-leader locomotion and reorientation keeping the shape change as small as possible. The basis for this is a novel shape-fitting approach for solving the inverse kinematics in only a few milliseconds. Shape fitting is performed by maximizing the similarity of two curves using Fréchet distance while simultaneously specifying the position and orientation of the end effector. Telemanipulation performance is investigated in a study in which 14 participants controlled a simulated snake robot to locomote into the target area. In a final validation, pivot reorientation within the target area is addressed.© 2023 IEEE. Personal use of this material is permitted.

description: Australia is recognised globally as a leader in the beef cattle industry, developing innovations in production systems and in both the domestic and export markets which have benefitted all beef value chain participants. One of the key reasons for its global recognition has been the design, implementation and ongoing improvement of the Meat Standards Australia (MSA) quality assurance scheme which was first trialled in 1998 and celebrated 25 years since commencement in 2023. In this paper the history of the development and implementation of MSA is reviewed, including its alignment with the theoretical principles of the economics of grading and the way in which the initial model has been modified over time.  Then, publicly available data is used to estimate the aggregate economic benefits to the industry from its implementation, and these benefits are compared with estimates of the costs incurred in researching, developing and operating the MSA model. The analysis shows that cattle producers, beef processors and beef consumers have all been beneficiaries of the program through the price premiums available for MSA graded beef and cattle. Based on the data available at the time of writing, at the retail level, annual gross benefits have risen substantially to over $400 million in the three years to 2022/23. The cumulative value to 2022/23 is estimated to be $3,125 million. These annual gross benefits are eventually distributed to producers, processors, retailers and consumers in relation to the relative slopes of the demand and supply curves at all the various market levels, as the market adjusts over time to the new level of domestic consumer willingness-to-pay for guaranteed tenderness. At the farm level in the last four years aggregate ‘over-the-hook’ returns have averaged around $200 million per year. The cumulative value to 2022/23 is estimated to be just under $2,200 million. Over the whole period 2004/05 to 2022/23, producers have received about 70 per cent of the total available willingness to pay. Impact assessment studies have shown that all past R&D expenditure in MSA has been covered, all industry adoption costs have been covered, all annual operating expenses have been covered, and on top of that, a substantial additional benefit has been generated.

description: In der heutigen Zeit sind numerische Feldsimulationen aus der Forschung und der Entwicklung komplexer elektronischer Geräte nicht mehr wegzudenken. Dennoch können sie bereits für vermeintlich einfache Probleme hinsichtlich der Rechenleistung und –dauer sehr aufwendig werden, was die Bereitstellung leistungsfähiger Rechentechnik notwendig macht. Des Weiteren sind kommerzielle Tools häufig sehr teuer und somit für Lehrzwecke, Privatpersonen oder Bildungseinrichtungen kaum zugänglich. In dieser Arbeit wird ein Ansatz präsentiert, der es ermöglicht Feldsimulationen im Webbrowser durchzuführen. Die Berechnung erfolgt lokal durch die Ausnutzung der Grafikkarte. Am Beispiel der Finite-Differenzen-Methode werden dabei die wesentlichen Schritte zur Umsetzung erläutert. Abschließend wird der implementierte Algorithmus mit kommerzieller Simulationssoftware verglichen.

description: Das Hochfrequenzverhalten elektrischer Leitungen unter dem Einfluss eines äußeren elektromagnetischen Feldes ist ein wichtiger Teil der EMV-Analyse, da die Signalund Versorgungsintegrität elektrischer Systeme stark durch die induzierten Ströme und Spannungen beeinträchtigt werden können (Abb. 1). Zur quantitativen Beurteilung des Verhaltens wurden in den letzten Jahren zahlreiche Modelle für den Spezialfall der homogenen Leitung mit linearer und nichtlinearer Beschaltung entwickelt (z.B. [1], [2]). In der Praxis treten aber auch häufig inhomogene Leitungsstrukturen (z.B. eine durchhängende Freileitung) auf, wobei die Anzahl der Modelle hierfür deutlich geringer ist. Viele Ansätze beschränken sich auf den Frequenzbereich und ein transientes Systemverhalten wird dabei durch eine IFFT ermittelt ([3], [4]), was die Verwendung nichtlinearer Bauelemente ausschließt. In diesem Beitrag wird das modale Ersatzschaltbild einer inhomogenen Leitung aus [5] durch modale Quellen erweitert, welche den Einfluss des einkoppelnden elektromagnetischen Feldes berücksichtigen. Durch eine quasistatische Analyse kann die Konvergenz des Modells beschleunigt werden, sodass die begrenzte Anzahl der Parallelschwingkreise sicher abgeschätzt werden kann. Da die Netzwerkparameter im Allgemeinen nicht analytisch vorliegen, werden diese mit Hilfe der Methode der Finiten Differenzen numerisch bestimmt. Das resultierende inhärent stabile Netzwerkmodell wird anhand eines transienten Beispiels mit nichtlinearer Beschaltung durch ein kommerzielles Feldberechnungsprogramm, welches durch eine aufwendige 3D-Vollwellensimulation, den Vector Fitting Algorithmus und anschließender Reduktion der Modellordnung ebenfalls ein Ersatzschaltbild aufstellt [6], validiert.

description: This paper aims at conceptualizing the approach followed in designing the building European network within the H2020 project “Short Supply Chain Knowledge and Innovation Network”. It was brought together literature regarding the adoption of network analysis and the development of short food supply chain in order to describe the role of the regional nodes as means to transfer knowledge along and between local food systems around European areas. This resulted into the framework of SKIN network design. The approach is devised to overcome the parochialism of local food systems, and structure an interconnected design among economic players to fulfill regional and global impacts in knowledge transfer.

description: We employ inelastic helium atom-surface scattering to measure the low energy phonon dispersion along high-symmetry directions on the surface of the topological insulator Bi$_2$Te$_3$. Results indicate that one particular low-frequency branch experiences noticeable mode softening attributable to the interaction between Dirac fermion quasiparticles and phonons on the surface. This mode softening constitutes a renormalization of the real part of the phonon self-energy. We obtain the imaginary part, and hence lifetime information, via a Hilbert transform. In doing so we are able to calculate an average branch specific electron-phonon coupling constant $ = 1.44$.

description: The objective of this article is to prepare for the initial certification according to IFS Global Markets Food V3 at the Landshuter Brauhaus AG private brewery at the Ellermühle site, which is expected in August 2025, and to create the basis for a potential follow-up certification according to IFS Food. The IFS Global Markets Food Program V3 is a standardized, voluntary and non-accredited assessment program for food companies, both for retail and manufacturer brand products (IFS 2023, p. 10 f.). It is based on the specifications of the Global Markets Program developed in 2008 (GFSI 2023a; VDOE 2020, p. 620).
The methodology of the target/actual analysis was used to work on the topic in order to be able to carry out a conformity check with regard to the requirements of IFS Global Markets Food V3 (see Appendix 3; IFS 2023). Observations, document analyses and employee surveys were carried out to obtain the most meaningful information possible. These have been recorded and evaluated within the target-performance analysis. A total of 65 deviations (equivalent to 53.7%) were identified at the basic level, and 60 deviations (equivalent to 82.2%) at the intermediate level. These were either processed as directly implemented corrective actions or formulated as recommendations for continuous improvement in the form of an action plan (see Appendix 15). The presentation of the action plan shows the deviations, the resulting measures, the associated responsibilities, the time period with the starting point and end point of the measures, and the current status. In addition a subdivision into "Basic" and "+Intermediate" was made for a better overview in the subsequent processing by the brewery.
A review as well as assessment of relevant requirements with regard to processes and significant violations after completion of the new building and commissioning at the Ellermühle site with regard to correlation with a potential "major" rating is recommended on the part of the operations manager or brewmaster (IFS 2023, p. 30).
After successful implementation of all recommendations of the basic level from the action plan, certification of the IFS Global Markets Food V3 at the basic level should be possible after completion of the Ellermühle site in August 2025. After subsequent processing of the action plan at the intermediate level, certification of IFS Global Markets Food V3 at the next higher level could then take place in the following year, August 2026.

description: Upon their formation, dynamically cool (collapsing) star clusters will, within only a few million years, achieve stellar mass segregation for stars down to a few solar masses, simply because of gravitational two-body encounters. Since binary systems are, on average, more massive than single stars, one would expect them to also rapidly mass segregate dynamically. Contrary to these expectations and based on high-resolution Hubble Space Telescope observations, we show that the compact, 15-30 Myr-old Large Magellanic Cloud cluster NGC 1818 exhibits tantalizing hints at the >= 2 sigma level of significance (> 3 sigma if we assume a power-law secondary-to-primary mass-ratio distribution) of an increasing fraction of F-star binary systems (with combined masses of 1.3-1.6 Msun) with increasing distance from the cluster center, specifically between the inner 10 to 20" (approximately equivalent to the cluster's core and half-mass radii) and the outer 60 to 80". If confirmed, this will offer support of the theoretically predicted but thus far unobserved dynamical disruption processes of the significant population of 'soft' binary systems---with relatively low binding energies compared to the kinetic energy of their stellar members---in star clusters, which we have access to here by virtue of the cluster's unique combination of youth and high stellar density.

description: The present paper discusses Marina Tsvetaeva’s essay about Maksimilian Voloshin The Living about the Living (1932) in the light of Tsvetaeva’s views on the legacy of the Silver Age in the early 1930s and her responses to the emergence of Socialist Realism in the Soviet Union. The essay demonstrates that Tsvetaeva presents herself as a strong advocate of modernist aesthetic principles that enable the reader both to experience the sense of estrangement and to reinvent classical themes in new contexts, so the notions of reading and transgression become entwined. It juxtaposes Tsvetaeva’s views on the use of myth in literature to several important trends related to the revival of ancient ritual and folk performance that occured in the 1910s-20s in Europe and in Russia (discussed in the works of Viacheslav Ivanov, Voloshin, Jane Harrison and Walter Benjamin).

description: The notion of epistemic justice helps interrogate existing practices of knowledge production, interpretation and use, leading to questions about “who” generates knowledge in society and how certain perspectives and forms of knowledge might be negated and marginalized as a part of a broader power structure. While knowledge is ‘the essence of education’ (Kotzee, 2017:348), debates around educational justice have tended to focus more on questions of redistribution (of access, resources, etc.) and recognition (of identities, cultures, etc.), than on the dimension of justice that is specifically related to knowledge, how it is accessed, distributed and produced within school settings. The notion of epistemic justice, which helps us consider such matters, has entered philosophical and educational debates somewhat more recently than other forms of justice. There is, therefore, a way to go in defining both what it means and how it can translate into school settings. We begin by proposing a positive definition of epistemic justice – in contrast to negative ones which define it by reference to forms of epistemic injustice; to then situate epistemic justice within broader epistemological and philosophical debates. We then develop a series of ideas in relation to how various instances of epistemic (in)justice can be found in educational settings. We explore both systemic and institutional educational dimensions, as well as the ways in which the curriculum, school materials, language use and pedagogies can be spaces in which educational (in)justice can play out.

Therefore we define an even smaller fragment D*-Horn and show that over finite successor structures it captures the complexity class P of all sets decidable in polynomial time. Furthermore, we show that the open D*-Horn-formulae correspond to the negative fragment of SO there exists-Horn.

description: In her article Raffaella Vassena explores the evolution of the autobiographical articles in Dostoevsky’s Diary of a Writer, especially those related to the author’s childhood, and how they came to have a minor role in the Diary of a Writer genre system. Ever since the last 1873 issue of the Diary of a Writer, the author attempts to resort to a peculiar type of memory, that of childhood memories, to which he demands a different function. In Dostoevsky’s view, childhood memories are an invaluable treasure – two or three good memories from a sad and painful childhood are able to guide a man to good deeds even in the most terrible moments of his adult life. Childhood memories can fight the social and moral plague that Dostoevsky openly denounces in the Diary of a Writer and to the defeat of which he mainly published his Diary: obosoblenie, a dissociation from traditional moral values, such as family and religion, occurring at every social level and due to the increasing diffusion of materialism. Dostoevsky pointed to the Diary of a Writer as a possible guiding light, and to a specifically Russian ethical-religious solution, able to join together and embrace the whole of humanity. In some Diary of a Writer issues Dostoevsky seems to ‘offer’ as a solution to the increasing dissociation his childhood memories. The fragments of the author’s individual memory are then transfigured into moments of a collective memory, removed and forgotten yet alive and sharable by the ideal reader.

description: An auto-tuning method for a Delta robot’s P/PI cascade motion controller using multi-objective optimization algorithm is proposed. The implemented control structure consists of two controllers: A feedforward controller based on a model of the inverse dynamics of the robot, and a cascade P/PI controller to compensate for unmodeled effects. The auto-tuning is achieved in the sense of optimizing the control parameters in three stages. In the first stage, the feedback control parameters are optimized after neglecting the feedforward control term. The goal is to minimize the position error in tracking an excitation trajectory, which is used as well to identify the dynamic model parameters in the second stage. After that, the feedforward compensation term is computed offline based on the desired trajectory. In the final stage, the P/PI parameters are optimized again after adding the feedforward controller. Experimental results on an industrial 3-dof Delta robot validates the efficiency of the proposed method.

description: A key component in the design of every drift tube ion mobility spectrometer (IMS) is the ion shutter which controls the injection of ions into the drift tube. Especially, compact drift tube IMS require very short injection pulses to achieve high resolution and therefore require fast ion shutters. Thus, it is important to find an ion shutter principle that can be readily scaled towards these short injection widths without causing major non-idealities in the injection process, such as drift field inhomogeneities, ion loss and ion discrimination by mobility. In this paper, we compare different ion shutter principles, foremost the Bradbury-Nielsen gate and a field switching design. It is shown through theoretical considerations and field simulations that the Bradbury-Nielsen shutter is more universally applicable and typically less complex for long injections widths but field inhomogeneities associated with its operating principle impede the scaling process. Thus, the currently less used field switching shutters will become the superior principle when very short injection widths are required, as this shutter principle allows for single digit microsecond widths.

description: Recent work of Brlek \textit{et al.} gives a characterization of digitally convex polyominoes using combinatorics on words. From this work, we derive a combinatorial symbolic description of digitally convex polyominoes and use it to analyze their limit properties and build a uniform sampler. Experimentally, our sampler shows a limit shape for large digitally convex polyominoes.

description: We analyzed the B and V light curves of two EA-type binaries V211 and NV358 using the WD code for the first time. Our analysis shows that V211 is a typical Algol-type binary and NV358 is a well detached binary system. As the two binaries are definite proper motion members of omega Centauri, we estimated their physical parameters, obtaining M_1=1.13\pm0.03M_\odot, R_1=0.98\pm0.01R_\odot and M_2=0.33\pm0.01M_\odot, R_2=0.92\pm0.01R_\odot for V211; M_1=1.30\pm0.05M_\odot, R_1=1.03\pm0.01R_\odot and M_2=0.58\pm0.02M_\odot, R_2=0.78\pm0.01R_\odot for NV358. On the color-magnitude diagram of omega Centauri, V211 is located in the faint blue straggler region and its primary component is more massive than a star at the main-sequence turnoff. Therefore, V211 is a blue straggler and should be formed by mass transfer from the secondary component to the primary. The age of NV358 is less than 1.93 Gyr, indicating that it is much younger than first-generation stars in omega Centauri. As NV364 in omega Centauri, NV358 should be a second-generation binary.

description: The demands placed on companies in terms of up-to-date quality and sustainability management as well as health and safety measures are high and are becoming increasingly complex. Increased legal requirements, additional industry standards and derived customer requirements constantly present companies and value chains with new challenges. The integrated approach to the implementation of these different requirements has already taken place in companies in recent years. However, small businesses still find it difficult to face the complexity of requirements on their own without an accompanying consultation. Qualint is a support tool, which is currently available in the 3rd version. The tool supports companies in setting up and continuously developing their integrated management system with coordinated hybrid service bundles. The focus is on combining the fields of action of quality, environmental and sustainability management as well as occupational safety and health.The article illustrates how quality management can be used as a basis for building up digital and organizational structures in companies and value chains. The focus is on sustainability aspects and ethical requirements that are closely related to people, such as occupational health and safety. Compliance with human rights is required in ISO 26000 and is also part of occupational safety and health. Furthermore, compliance with human rights and corresponding working conditions is also regulated by the new Supply Chain Duty Act (LkSG). It shows how demands on companies have grown and how the consulting tool Qualint has developed accordingly.

description: The notion of epistemic justice helps interrogate existing practices of knowledge production, interpretation and use, leading to questions about “who” generates knowledge in society and how certain perspectives and forms of knowledge might be negated and marginalized as a part of a broader power structure. While knowledge is ‘the essence of education’ (Kotzee, 2017:348), debates around educational justice have tended to focus more on questions of redistribution (of access, resources, etc.) and recognition (of identities, cultures, etc.), than on the dimension of justice that is specifically related to knowledge, how it is accessed, distributed and produced within school settings. The notion of epistemic justice, which helps us consider such matters, has entered philosophical and educational debates somewhat more recently than other forms of justice. There is, therefore, a way to go in defining both what it means and how it can translate into school settings. We begin by proposing a positive definition of epistemic justice – in contrast to negative ones which define it by reference to forms of epistemic injustice; to then situate epistemic justice within broader epistemological and philosophical debates. We then develop a series of ideas in relation to how various instances of epistemic (in)justice can be found in educational settings. We explore both systemic and institutional educational dimensions, as well as the ways in which the curriculum, school materials, language use and pedagogies can be spaces in which educational (in)justice can play out.

description: For creating robots that are capable of human-like performance in terms of speed, energetic properties, and robustness, intrinsic compliance is a promising design element. In this paper, we investigate the principle effects of elastic energy storage and release for basketball dribbling in terms of open-loop cycle stability. We base the analysis, which is performed for the 1-degree-of-freedom (DoF) case, on error propagation, peak power performance during hand contact, and robustness with respect to varying hand stiffness. As the ball can only be controlled during contact, an intrinsically elastic hand extends the contact time and improves the energetic characteristics of the process. To back up our basic insights, we extend the 1-DoF controller to 6-DoFs and show how passive compliance can be exploited for a 6-DoF cyclic ball dribbling task with a 7-DoF articulated Cartesian impedance controlled robot. As a human is able to dribble blindly, we decided to focus on the case of contact force sensing only, i.e., no visual information is necessary in our approach. We show via simulation and experiment that it is possible to achieve a stable dynamic cycle based on the 1-DoF analysis for the primary vertical axis together with control strategies for the secondary translations and rotations of the task. The scheme allows also the continuous tracking of a desired dribbling height and horizontal position. The approach is also used to hypothesize about human dribbling and is validated with captured data.
