Selbstsorge als Selbstzweck? Bedeutung und Formen von Selbstsorge in Diskursen über gute Mutterschaft
Authors: Décieux Fabienne , Schmidt Eva-Maria , Zartler Ulrike 
Published: June 2024

ZusammenfassungIn diesem Beitrag fragen wir, welche Bedeutung Selbstsorge für Mütter in kollektiven Diskursen über gute Mutterschaft hat und welche Formen der Selbstsorge in diesem Zusammenhang diskutiert werden. Infolge neoliberaler Tendenzen wird eine strukturelle Sorglosigkeit deutlich, und es kommt zu Krisen in Arbeits- und Sorgearrangements. Gleichzeitig wird Selbstsorge als Aufgabe etabliert, ohne einen adäquaten Rahmen dafür zu schaffen. Diese Aufgabe betrifft auch Mütter, die jedoch ebenso als hauptverantwortlich für Fürsorge betrachtet und mit Anforderungen der Erwerbssphäre konfrontiert werden. In diesem Spannungsfeld wird Selbstsorge für Mütter komplex und potenziell prekär. Dennoch gibt es bislang wenig empirische Forschungsarbeiten zur Bedeutung und zu den Formen mütterlicher Selbstsorge. Wir adressieren diese Forschungslücke auf Basis von 24 geschlechtshomogenen und -heterogenen Gruppendiskussionen mit insgesamt 173 Teilnehmenden, die in verschiedenen Regionen in Österreich durchgeführt und mit rekonstruktiven Methoden analysiert wurden. Die Ergebnisse zeigen, dass Selbstsorge für Mütter als Zugeständnis konstruiert wurde und zwei Formen mütterlicher Selbstsorge im Fokus der Diskussionen standen: Erstens die Selbstsorge in Form von Zeit zur Reproduktion des fürsorglichen Selbst; zweitens die Selbstsorge in Form von Erwerbsarbeit zur materiellen Existenzsicherung. Beide Formen der Selbstsorge sind prekär, da sie eine Verpflichtung zur Selbstsorge seitens der Mütter beinhalten mit dem Ziel der Aufrechterhaltung optimaler Fürsorge und der Gemeinschaft nicht zu Last zu fallen. Selbstsorge dient als Stütze traditioneller familialer und gesellschaftlicher Arbeits- und Sorgearrangements, sie stabilisiert so die bestehende strukturelle Sorglosigkeit.

Published: June 2024

ZusammenfassungIn den letzten Jahren wurden vermehrt Online-Fortbildungen hinsichtlich ihrer Wirkungen untersucht und positive Effekte des digitalen Formats ausgemacht. Wenig empirische Evidenz gibt es dafür, wie sich digitale und Präsenz-Fortbildungen in Bezug auf ihre konkrete Durchführung unterscheiden. Im Beitrag werden acht videographierte Fortbildungen einer Fortbildungsreihe, die durch zwei Fortbildner:innen-Tandems in Präsenz und digital durchgeführt wurden, untersucht. Dabei werden Phasierung und Strukturierung der Fortbildungen sowie Moderationsstrategien analysiert. Die Ergebnisse zeigen, dass sich die beiden Formate in vielen Aspekten nicht unterscheiden. Allerdings bleibt im digitalen Format weniger Zeit für die Durchführung von Aktivitäten sowie Diskussionen, da mehr Zeit für technische Erläuterungen aufgewendet wird. In den Präsenz-Fortbildungen wurden die Lehrkräfte tendenziell stärker unterstützt, kooperierten eher miteinander und Feedback- sowie Reflexionsphasen wurde mehr Zeit eingeräumt. Für die Moderationsstrategien konnten keine Unterschiede, aber ein stabiler Trend ausgemacht werden: Eher wurden Beiträge von Lehrkräften eingefordert, statt eigene Beiträge in die Diskussion einzubringen. Die Ergebnisse liefern wichtige Erkenntnisse dahingehend, wie Fortbildner:innen fachdidaktischer Fortbildungen auf digitale Formate vorbereitet werden können.

AbstractPreviously, our group established a surgical gesture classification system that deconstructs robotic tissue dissection into basic surgical maneuvers. Here, we evaluate gestures by correlating the metric with surgeon experience and technical skill assessment scores in the apical dissection (AD) of robotic-assisted radical prostatectomy (RARP). Additionally, we explore the association between AD performance and early continence recovery following RARP. 78 AD surgical videos from 2016 to 2018 across two international institutions were included. Surgeons were grouped by median robotic caseload (range 80–5,800 cases): less experienced group (< 475 cases) and more experienced (≥ 475 cases). Videos were decoded with gestures and assessed using Dissection Assessment for Robotic Technique (DART). Statistical findings revealed more experienced surgeons (n = 10) used greater proportions of cold cut (p = 0.008) and smaller proportions of peel/push, spread, and two-hand spread (p < 0.05) than less experienced surgeons (n = 10). Correlations between gestures and technical skills assessments ranged from − 0.397 to 0.316 (p < 0.05). Surgeons utilizing more retraction gestures had lower total DART scores (p < 0.01), suggesting less dissection proficiency. Those who used more gestures and spent more time per gesture had lower efficiency scores (p < 0.01). More coagulation and hook gestures were found in cases of patients with continence recovery compared to those with ongoing incontinence (p < 0.04). Gestures performed during AD vary based on surgeon experience level and patient continence recovery duration. Significant correlations were demonstrated between gestures and dissection technical skills. Gestures can serve as a novel method to objectively evaluate dissection performance and anticipate outcomes.

The End of Inclusive Resettlement: Experiencing Unaffordability within State Housing Programmes in Salé, Morocco
Authors: Beier Raffael 
Published: June 2024

AbstractSince the early 2000s, Morocco’s government is running the Villes Sans Bidonville programme (VSBP) as a literal reference to international policy claims for Cities Without Slums. Initially and in contrast to past, unsuccessful attempts to eradicate the country’s bidonvilles, more inclusive resettlement schemes – participatory and affordable for all – should help to avoid that residents resell resettlement housing and move back to bidonvilles. However, this article shows that with the advancement of VSBP, more recent resettlement has become authoritarian, exclusionary, and unaffordable again. Large numbers of low-income households of one of Rabat/Salé’s last bidonvilles are effectively excluded from accessing resettlement housing, because they cannot afford the construction of a house on their assigned resettlement plot. For many, reselling their plot is the only option to access alternative housing after displacement. Building on narrative and biographic interviews with displaced former bidonville residents who are not living at the resettlement site, this article looks at how displaced bidonville dwellers cope with housing unaffordability. Where do people move why if affordable informal housing is demolished and state-subsidised alternatives are inaccessible? The results show how unaffordable resettlement schemes divide established bidonville communities, leaving the most vulnerable residents behind. Furthermore, they highlight people’s severe constraints, struggles, and uncertainties in seeking to achieve decent residential stability outside stressful rental accommodation.

AbstractRice and millet arrived in Western Japan from Korea around 3,000 years ago and spread eastwards across the archipelago in the next 700 years. However, the extent to which agriculture transformed traditional Jōmon hunter-gatherer-fisher communities is debated. Central Japan is a key area of study as remodelling of radiocarbon dates shows a slowdown in the dispersal rate of rice agriculture in this area. Here, we examine and compare the use of pottery by Final Jōmon and Early to Middle Yayoi communities in the Tōkai and the Central Highland regions of central Japan, using lipid residue analysis. Although the identification of specific biomarkers for rice remains elusive, an increase in the ratio of E/H C18 APAAs with the arrival of rice and millet indicates a potential change in plant processing and consumption. We were also able to identify biomarkers for broomcorn millet (miliacin) in both Final Jōmon and Yayoi pottery. However, evidence for millet consumption is sparse and in all cases was likely mixed with wild hunted and foraged foods. We conclude therefore that, despite the introduction of rice and millet agriculture in central Japan, pre-existing diets and culinary habits of Jōmon hunter-gatherers remain important.

Abstract
Background
Immune checkpoint inhibitors (ICIs), especially those targeting programmed cell death-1 (PD-1) and programmed cell death ligand-1 (PD-L1), have introduced a new treatment landscape for many types of tumors. However, they only achieve a limited therapeutic response. Hence, identifying patients who may benefit from ICIs is currently a challenge.

Methods
47 tumor patients harboring ARID1A mutations were retrospectively studied. The genomic profiling data through next-generation sequencing (NGS) and relevant clinical information were collected and analyzed. Additionally, bioinformatics analysis of the expression of immune checkpoints and immune cell infiltration levels was conducted in ARID1A-mutant gastric cancer (GC).

Results
ARID1A mutations frequently co-occur with mutations in DNA damage repair (DDR)-associated genes. Among the 35 ARID1A-mutant patients who received immunotherapy, 27 were evaluable., with the objective response rate (ORR) was 48.15% (13/27), and the disease control rate (DCR) was 92.59% (25/27). Moreover, survival assays revealed that ARID1A-mutant patients had longer median overall survival (mOS) after immunotherapy. In ARID1A-mutated GC patients, receiving ICIs treatment indicated longer progressive-free survival (PFS). Additionally, the incidence of microsatellite instability-high (MSI-H), high tumor mutation burden (TMB-H) and Epstein‒Barr virus (EBV) infection was elevated. Bioinformatic analysis showed significant enrichment of immune response and T cell activation pathway within differentially expressed genes in ARID1A-mutant GC group. Finally, ARID1A mutations status was considered to be highly correlated with the level of tumor infiltrating lymphocytes (TILs) and high expression of immune checkpoints.

Conclusions
Patients with tumors harboring ARID1A mutations may achieve better clinical outcomes from immunotherapy, especially in GC. ARID1A mutations can lead to genomic instability and reshape the tumor immune microenvironment (TIME), which can be used as a biomarker for immunotherapy.

Zusammenfassung
Die Frage nach den Anforderungen in Abiturprüfungen in Mathematik wird immer wieder kontrovers diskutiert. Dabei stehen oft konkrete Aufgabenstellungen im Fokus. Mit der hier vorgelegten Studie möchten wir einen Beitrag leisten, diese Diskussion durch eine systematische Analyse von Abituraufgaben zu fundieren. Leitend ist dabei die Frage nach dem kognitiven Potenzial der Aufgaben mit Blick auf die allgemeinen mathematischen Kompetenzen, die tangierten Grundvorstellungen und die verwendeten technischen Hilfsmittel.
Betrachtet wurden vierzehn Abituraufgaben mit 203 bewerteten Arbeitsaufträgen aus dem Aufgabenpool des Instituts für Qualitätsentwicklung im Bildungswesen (IQB), in dem exemplarische Abituraufgaben im Rahmen des Zentralabiturs als Orientierung öffentlich zur Verfügung stehen. Konkret wurden Analysis-Aufgaben aus den Jahren 2020 und 2021 in die Studie einbezogen. Für die Analyse wurde ein Kodiermanual auf der Grundlage des COACTIV-Manuals entwickelt und um Analysekriterien mit Blick auf die Mediennutzung ergänzt, das auch zukünftig als Instrument für Prozesse der Aufgaben- und Qualitätsentwicklung in der Sekundarstufe II genutzt werden kann.
Als Ergebnis der Studie lässt sich ein generell niedriges Niveau hinsichtlich des kognitiven Potenzials in allen untersuchten allgemeinen mathematischen Kompetenzen wie dem Argumentieren, Problemlösen, Modellieren oder Kommunizieren (als Verfassen von Text) konstatieren. Auch Grundvorstellungen werden nur wenig durch die Aufgabenstellungen angesprochen. Es bestehen kaum Unterschiede zwischen den Aufgaben mit unterschiedlichen Hilfsmitteln (Computeralgebra (CAS) und wissenschaftlicher Taschenrechner), wobei gerade die Potenziale von CAS nur wenig ausgenutzt werden. Diese Ergebnisse werden diskutiert und in Hinblick auf eine Weiterentwicklung von Abituraufgaben eingeordnet.

Published: June 2024

AbstractThis research paper presents a comprehensive study of the simultaneous localization and mapping (SLAM) algorithm for robot localization and navigation in unknown environments. The SLAM algorithm is a widely used approach for building a map of an environment and estimating the robot’s position within it, which is especially useful in dynamic and unstructured environments. The paper discusses various SLAM techniques, including the Kalman filter (KF) and GraphSLAM algorithms, and their use in probabilistic estimation of the robot’s position and orientation. The paper also explores different path-planning techniques that can be used with the map created by the SLAM algorithm to generate collision-free paths for the robot to navigate toward its goal. The paper also discusses recent advances in deep learning-based SLAM algorithms and their applications in indoor navigation with ORB and RGB-D cameras. The research concludes that SLAM-based robot localization and navigation algorithms are a promising approach for robots navigating in unstructured environments and present various opportunities for future research.
Chinese Named Entity Recognition method based on multi-feature fusion and biaffine

Published: June 2024

AbstractChinese Named Entity Recognition (CNER) focuses on precisely identifying predefined structural categories in unstructured Chinese text. Most existing CNER models do not consider the unique glyph and pinyin features of Chinese characters, but the rich semantic features hidden behind these features have a good effect on enhancing the judgment ability of language models. At the same time, it is difficult to identify the boundaries of Chinese nested entities, and accurately identifying the boundaries of entities within nested entities is also a difficult problem to solve. We propose a CNER method based on multi-feature fusion technology and biaffine mechanism to address the above issues: In the input representation layer, integrate the glyph and pinyin features of Chinese characters together, intuitively capturing the semantics of Chinese characters. Furthermore, biaffine mechanism has been introduced to provide a comprehensive view of the input on a global scale. This mechanism effectively converts the task of entity recognition into a problem of assigning scores to spans, hence enhancing the precision of identifying entity borders. In order to evaluate the efficacy of the model, a series of experiments were done on three Chinese entity recognition datasets: Resume, MSRA, and People Daily. The experimental results show that the solid boundary can be identified more accurately, and the F1 values of 96.49%, 96.26% and 96.19% are obtained respectively, which has a better recognition effect than the baseline model.
Improving two-layer encoding of evolutionary algorithms for sparse large-scale multiobjective optimization problems

Published: June 2024

AbstractSparse large-scale multiobjective problems (LSMOPs) are characterized as an NP-hard issue that undergoes a significant presence of zero-valued variables in Pareto optimal solutions. In solving sparse LSMOPs, recent studies typically employ a specialized two-layer encoding, where the low-level layer undertakes the optimization of zero variables and the high-level layer is in charge of non-zero variables. However, such an encoding usually puts the low-level layer in the first place and thus cannot achieve a balance between optimizing zero and non-zero variables. To this end, this paper proposes to build a two-way association between the two layers using a mutual preference calculation method and a two-way matching strategy. Essentially, the two-way association balances the influence of two layers on the encoded individual by relaxing the control of the low-level layer and enhancing the control of the high-level layer, thus reaching the balance between the optimizations of zero and non-zero variables. Moreover, we propose a new evolutionary algorithm equipped with the modules and compare it with several state-of-the-art algorithms on 32 benchmark problems. Extensive experiments verify its effectiveness, as the proposed modules can improve the two-layer encoding and help the algorithm achieve superior performance on sparse LSMOPs.
Advances in cavity-enhanced methods for high precision molecular spectroscopy and test of fundamental physics

Published: June 2024

AbstractCavity-enhanced spectroscopic techniques are highly sensitive laser-based methods for interrogating the atomic and molecular constituents of any gaseous medium that is confined into an optical resonator. A first advantage over conventional absorption spectroscopy comes from the extremely long path length of the laser radiation inside the stable, high-finesse, optical cavity, which allows the sample to be probed over several tens of kilometers. After more than 30 years of research and development, techniques like cavity ring-down spectroscopy, cavity-enhanced absorption spectroscopy, and noise-immune cavity-enhanced optical-heterodyne molecular spectroscopy, have reached extraordinary levels of detection sensitivity, such that it is possible to measure light absorption from molecules in trace amounts or extremely weak spectral lines of more abundant species. A second advantage of the use of high-finesse cavities lies in the power amplification achieved inside the optical resonator, making it possible to saturate even weak transitions, thus reducing the width of spectral lines by some three orders of magnitude. Combining these methods with frequency comb technologies has further enhanced their capabilities, adding metrology-grade qualities to spectroscopic determinations such as transition frequencies of molecular resonances, which can be measured with sub-kHz accuracy. In this review article, we discuss the current status of highly precise and highly sensitive laser spectroscopy for fundamental tests and measurements. We describe state-of-the-art molecular spectroscopy methods and their application to a few selected molecules of fundamental importance in understanding quantum chemistry theories or testing quantum electrodynamics.
A comprehensive analysis of high-temperature material extrusion 3D printing parameters on fracture patterns and strength of polyetheretherketone cranial implants

AbstractA polyetheretherketone (PEEK) cranial implant is one of the most well-known polymeric implants used in cranioplasty. However, most off-the-shelf PEEK cranial implants are developed by molding and then sized into the patient's defect anatomy by machining, which is time-consuming and capital-intensive. On the contrary, 3D printing, specifically material extrusion, can develop patient-specific cranial implants that precisely fit the defect anatomy, ensuring stable fixation and restoring esthetic cranial symmetry. However, 3D printing high-quality, mechanically robust PEEK implants are challenging due to the high thermal processing conditions required for PEEK printing, its high melt viscosity, and its susceptibility to incomplete crystallization. If appropriately attuned, an optimized set of 3D printing conditions can yield high-quality patient-specific PEEK cranial implants with clinically relevant mechanical properties. Hence, in this study, we comprehensively analyzed the effect of essential 3D printing conditions on cranial implants' material and mechanical properties. Specifically, we varied critical 3D printing material extrusion parameters, such as build orientation, nozzle, bedplate, chamber temperature, and print speed, and analyzed their effect on the implants' impact strength. We also used microscopy and Finite Element Analysis to understand the implants' fracture patterns with the impact indentor's impact. Based on our research, we determined an optimized set of 3D printing conditions to yield cranial implants with appropriate impact strength. Our results revealed that specimens printed at 0° build orientation, i.e., parallel to the bedplate, with optimum printing parameters, such as nozzle, bedplate, chamber temperature, and print speed, sustained a peak force of 2034 N. We envision that this study will help implant manufacturers utilize high-temperature material extrusion 3D printing to develop patient-specific PEEK cranial implants with clinically viable mechanical properties.
