Neue Querschnitte von Stahlverbundbrücken – Teil 1: Ermüdungsfestigkeit der querbelasteten zugbeanspruchten Fahrbahnplatte
Authors: Stempniewski Lena , Kuhlmann Ulrike , Geißler Karsten 
Published: March 2023

AbstractBei Verbundgroßbrücken, die über mehrere Felder spannen, kommt es aufgrund negativer Momentenbeanspruchung im Stützbereich zu Rissen infolge der Zugbeanspruchung in der Betonfahrbahn. Die Anordnung von stählernen Kragträgern im Querrahmenabstand unter der Fahrbahnplatte (u. a. zur Auflagerung von Teilfertigteilen) führt zu einer überwiegend längsspannenden Fahrbahnplatte, auf die direkt die Radlasten aus Verkehr wirken. Das heißt, die zyklische Querkraft infolge der lokalen Radlasten muss über die infolge der globalen Zugbeanspruchung gerissene Fahrbahnplatte zu den Querträgern übertragen werden. Derzeit wird für diesen Anwendungsfall die Rissbreite konservativ auf 0,15 mm begrenzt. Es werden Versuche und deren Ergebnisse vorgestellt, die Aufschluss über das Tragverhalten der gezogenen und damit gerissenen Betonfahrbahnplatte unter einer ermüdungswirksamen Querkraft liefern. Dazu zählen zum einen Einstufenversuche mit dem Ziel, das Tragverhalten zu klären und Parameter zu identifizieren, die die Ermüdungsfestigkeit beeinflussen. Weiterhin wurde zusätzlich in Mehrstufenversuchen der Einfluss einer realitätsnahen Beanspruchung mit wechselnder Belastungshöhe auf die Ermüdungsfestigkeit getestet und die Anwendung der linearen Schadensakkumulationshypothese nach der Palmgren‐Miner‐Regel überprüft.

Published: March 2023

AbstractZinc air batteries (ZABs) are gaining popularity as a viable substitute for lithium‐based batteries in recent years because of their availability of raw materials, high energy density, affordability, and renewability. However, there remain challenges that have not been solved, like the lack of bifunctional catalysts that would increase the kinetics of oxygen reduction and oxygen evolution reactions (ORR and OER) in the cathodic layer of ZABs. Transition metal‐based catalyst (TMBCs) credited with high activity, stability and affordability are researched as a potential bifunctional catalyst. The review that is being presented intend to provide an overview of ZABs, specific information about TMBC types utilized in ZABs, as well as an explanation of the functions of artificial intelligence (AI) and machine learning (ML).This article is categorized under:

Orality/Aurality and Voice of the Voiceless Mother in Abla Farhoud’s Happiness Has a Slippery Tail
Authors: Kačkutė Eglė 
Published: March 2023

AbstractThe problem of the representation of the mother’s voice and the maternal perspective in literary fiction has been a concern of contemporary scholarship in women’s writing for several decades. This chapter explores the literary representation of the voice and the perspective of a seemingly voiceless migrant mother who is silent in the language of the host country through the novelHappiness Has a Slippery Tail(1998) (Le bonheur a la queue glissante) by the Canadian Quebecois author of Lebanese origin, Abla Farhoud. This chapter demonstrates that in terms of literary representation of the mother’s voice, matrifocal migrant women’s writing relies on the orality of the mother’s voice to articulate the experience of mothering across the language barrier. It argues that the novel tells the story of a marginalised migrant mother in two voices: the aural voice of a marginalised mother who is voiceless in French and in writing (she is illiterate) and that of a French-educated writer daughter who understands the quality of the mother’s voice in Arabic. In this way the voice of the silent mother can be heard by the Western readership, and her perspective inscribed in the Western literary tradition.
Qualifications as Guarantees of Proficiency: Do We Understand Their Role?
Authors: Winch Christopher 
Published: March 2023

AbstractA professional qualification should be a guarantee of the professional ability of its holder. But how do we know that a qualification is a guarantee given the variegated nature of the successful exercise of professional ability in a wide variety of complex and unique and often unexpected circumstances? One of the problems involved in professional qualification design concerns path dependency in the way in which qualifications are constructed. We tend to design qualifications according to categories that tradition and culture have handed down instead of asking whether they meet the current needs of professions. In this chapter I will suggest that professional curriculum designers be presented with a series of ‘decision points’ so that they are obliged to explicitly consider whether certain attributes need to be included in the qualification. These attributes will need to include far more than ‘skill’. This claim is illustrated with examples from some of the professions associated with low energy construction.
Es wimmelt von Henne-Ei-Problemen: Transformation als koevolutionärer Prozess
Authors: Jacob Klaus 
Published: March 2023

ZusammenfassungEs stellt sich nicht nur aus Umweltsicht, sondern auch aus der Perspektive sozialpolitischer Akteure ein weitreichender Transformationsbedarf. Ernährung, Wohnen, Verkehr, Gesundheit, Bildung lassen sich nach Auffassung vieler nicht mehr mit kleinschrittigen Verbesserungen sichern, sondern es wird nach grundlegendem Wandel gefragt. Natürliche Ressourcen zu extrahieren und die Umwelt als Deponie für Schadstoffe und Abfälle zu nutzen, ist genauso wie die Ausbeutung von Arbeit eine Möglichkeit, um Kosten zu reduzieren und in der Konkurrenz mit anderen Unternehmen Vorteile zu erringen. Die gemeinsame Formulierung der Veränderungsanliegen durch sozial- und umweltpolitische Akteure wäre ein starker Impuls für eine Beschleunigung tiefgreifender Prozesse nachhaltigen Wandels. Wenn ein dominanter gesellschaftlicher Diskurs entsteht, in dem sich die Delegitimation des Bisherigen und die Machbarkeit und Vorteilhaftigkeit einer Alternative miteinander verbinden, hat das eine enorme Wirkung: Es gibt dem ungerichteten Innovationsgeschehen in den Nischen eine Richtung, verbindet und koordiniert das Handeln von Akteuren in eine gemeinsame Richtung. Das Geschehen erfährt große Dynamik.
Solidarität: Konstellationen und Dynamiken in der Spätmoderne
Authors: August Vincent 
Published: March 2023

ZusammenfassungSolidarität ist eine paradoxe Leitidee der modernen Gesellschaft. Durch ihre übergreifende Zustimmung werden aber die Funktionsweisen und Folgen von Solidarität oftmals nicht hinreichend bedacht. Der Beitrag nimmt daher anhand konkreter Beispiele (Konservatismus, Arbeiterbewegung, Pandemie, Krieg gegen die Ukraine) die Geschichte und Funktionsweise von Solidarität in den Blick. Er untersucht typische Dynamiken (moralische Selbstorganisation, Eskalation, Burnout) und diskutiert Strategien des Umgangs mit diesen Dynamiken und ihre Folgen (Verrechtlichung, Bürokratisierung, Demobilisierung). Schließlich wendet sich der Beitrag den gesellschaftlichen Konstellationen der Gegenwart zu. Der Formwandel von Arbeit und Politik in der Spätmoderne bringt auch veränderte Bedingungen für klassische Solidaritätsakteure mit sich. Gleichzeitig haben wir es mit einer veränderten Konfliktstruktur zu tun, in der konkurrierende Solidaritätsansprüche aufeinanderprallen. Auf beiden Seiten wird dann mehr Solidarität gefordert, gerade dadurch bekommen wir aber mehr Konflikt. Dieses Solidaritätsparadox erfordert kluges Konfliktmanagement.
Der Pararectus-Zugang: operatives Vorgehen in der Acetabulumchirurgie
Authors: von Rüden Christian , Brand Andreas , Perl Mario 
Published: March 2023

Zusammenfassung
Operationsziel
Der Pararectus-Zugang wurde vor einigen Jahren für die Beckenchirurgie neu entdeckt und als alternativer Zugang insbesondere für die Behandlung von Acetabulumfrakturen des vorderen Pfeilers mit Beteiligung der quadrilateralen Fläche beschrieben.

Indikationen
Zur optimalen Darstellung von Acetabulumfrakturen mit Beteiligung der quadrilateralen Fläche, Frakturen der vorderen Wand und des vorderen Pfeilers, vorderen Pfeiler/hinteren Hemiquerfrakturen und Frakturen mit zentraler Impression von Domfragmenten hat sich der Pararectus-Zugang bewährt.

Kontraindikationen
Bei Frakturen des hinteren Pfeilers, der hinteren Wand, kombinierten Frakturen der hinteren Wand und des hinteren Pfeilers, Querfrakturen mit Dislokation des hinteren Pfeilers oder in Kombination mit Frakturen der hinteren Wand und bei T‑Frakturen mit Dislokation des hinteren Pfeilers oder in Kombination mit Frakturen der hinteren Wand findet der Pararectus-Zugang keine Anwendung, ebenso nicht bei Patienten mit Ileus.

Operationstechnik
Über den Pararectus-Zugang kann der gesamte Beckenring einschließlich der quadrilateralen Fläche erreicht werden. Die Auswahl der chirurgischen Fenster richtet sich nach der Frakturlokalisation und den Erfordernissen der Frakturreposition.

Weiterbehandlung
Grundsätzlich sollte eine Teilbelastung für 6 Wochen eingehalten werden, wobei Fraktur- und Osteosynthese-abhängig ggf. eine frühere Belastungsfreigabe möglich ist. Insbesondere von geriatrischen Patienten kann häufig keine Teilbelastung eingehalten werden, sodass hier die frühzeitige und oft relativ unkontrollierte Vollbelastung akzeptiert werden muss.

Ergebnisse
In einer vergleichenden instrumentellen Bewegungsanalyse zwischen Patienten nach operativer Stabilisierung einer isolierten unilateralen Acetabulumfraktur über den Pararectus-Zugang und gesunden Probanden zeichnete sich schon in der frühen postoperativen Phase eine suffiziente Stabilität und Bewegungsfunktion des Beckens und der Hüfte während des Gehens ab.

AbstractIsolation and detection of microplastics (MP) in marine samples is extremely cost- and labor-intensive, limiting the speed and amount of data that can be collected. In the current work, we describe rapid measurement of net-collected MPs (net mesh size 300 µm) using a benchtop near-infrared hyperspectral imaging system during a research expedition to the subtropical North Atlantic gyre. Suspected plastic particles were identified microscopically and mounted on a black adhesive background. Particles were imaged with a Specim FX17 near-infrared linescan camera and a motorized stage. A particle mapping procedure was built on existing edge-finding algorithms and a polymer identification method developed using spectra from virgin polymer reference materials. This preliminary work focused on polyethylene, polypropylene, and polystyrene as they are less dense than seawater and therefore likely to be found floating in the open ocean. A total of 27 net tows sampled 2534 suspected MP particles that were imaged and analyzed at sea. Approximately 77.1% of particles were identified as polyethylene, followed by polypropylene (9.2%). A small fraction of polystyrene was detected only at one station. Approximately 13.6% of particles were either other plastic polymers or were natural materials visually misidentified as plastics. Particle size distributions for PE and PP particles with a length greater than 1 mm followed an approximate power law relationship with abundance. This method allowed at-sea, near real-time identification of MP polymer types and particle dimensions, and shows great promise for rapid field measurements of microplastics in net-collected samples.
Internal architecture of the proximal femur: calcar femorale or Adams’ arch?
Authors: Bartoníček Jan , Alt Jan , Naňka Ondřej 
Published: March 2023

Abstract
Purpose
The calcar femorale (femoral calcar) is used in the English literature to designate the thickened medial cortex of the femoral neck. This term is, however, incorrect, as the calcar femorale is actually quite another structure.

Methods
Searching was performed in original and historic publication.

Results
The importance of the thickened medial cortex of the proximal femur in femoral neck fractures was discussed already by Robert Adams in 1834–1836. Therefore, the German surgeon C.W. Streubel, in 1847, called it Adamscher Knochenbogen (Adams’ arch). Due to misspelling, this term was gradually changed to Adambogen, and at the turn of twentieth century, it was commonly used primarily in the German literature. Then, it fell into oblivion and its “renaissance” came as late as during the 1960s, again in the German literature, in connection with operative treatment of trochanteric fractures.

Conclusions
However, under the influence of the English literature, it has been replaced by the term calcar femorale (femoral calcar), used ever since. The term Adams’ arch should be reserved for the thickened medial cortex of the proximal femur, while the term calcar femorale (femoral calcar) should be used for the vertical plate arising from the medial cortex close below the lesser trochanter.

AbstractAdolescent refugees and asylum seekers (ARAS) are highly vulnerable to mental health problems. Stepped care models (SCM) and culturally sensitive therapies offer promising treatment approaches to effectively provide necessary medical and psychological support. To our knowledge, we were the first to investigate whether a culturally sensitive SCM will reduce symptoms of depression and PTSD in ARAS more effectively and efficiently than treatment as usual (TAU). We conducted a multicentric, randomized, controlled and rater-blinded trial across Germany with ARAS between the ages of 14 to 21 years. Participants (N = 158) were stratified by their level of depressive symptom severity and then equally randomized to either SCM or TAU. Depending on their severity level, SCM participants were allocated to tailored interventions. Symptom changes were assessed for depression (PHQ) and PTSD (CATS) at four time points, with the primary end point at post-intervention after 12 weeks. Based on an intention-to-treat sample, we used a linear mixed model approach for the main statistical analyses. Further evaluations included cost–utility analyses, sensitivity analyses, follow-up-analyses, response and remission rates and subgroup analysis. We found a significant reduction of PHQ (d = 0.52) and CATS (d = 0.27) scores in both groups. However, there was no significant difference between SCM and TAU. Cost–utility analyses indicated that SCM generated greater cost–utility when measured as quality-adjusted life years compared to TAU. Subgroup analysis revealed different effects for the SCM interventions depending on the outcome measure. Although culturally sensitive, SCMs did not prove to be more effective in symptom change and represent a more cost-effective treatment alternative for mentally burdened ARAS. Our research contributes to the optimization of clinical productivity and the improvement of therapeutic care for ARAS. Disorder-specific interventions should be further investigated.
Analyzing the effect of health reforms on the efficiency of Ecuadorian public hospitals
Authors: Piedra-Peña Juan , Prior Diego 
Published: March 2023

AbstractThis study aims to assess whether Ecuadorian health reforms carried out since 2008 have affected the efficiency performance of public hospitals in the country. We contribute to the literature by shedding new light on the effects on public healthcare efficiency for developing countries when policies move toward health equity and universal coverage. We follow a two-stage approach, wherein the first stage we make use of factor and cluster analysis to obtain three clusters of public hospitals based on their technological endowment; we exploit Data Envelopment Analysis for panel data in the second stage to estimate robust efficiency measures over time. Our innovative empirical strategy considers the heterogeneity of healthcare institutions in the analysis of their efficiency performance. The results show a significant decrease in the average efficiency of low and intermediate technology hospitals after the new constitution was adopted in 2008. The decline in efficiency coincides with the two reforms of 2010 and 2011 that brought on higher social security coverage.
The influence of micro-expressions on deception detection

Published: March 2023

AbstractFacial micro-expressions are universal symbols of emotions that provide cohesion to interpersonal communication. At the same time, the changes in micro-expressions are considered to be the most important hints in the psychology of emotion. Furthermore, analysis and recognition of these micro-expressions have pervaded in various areas such as security and psychology. In security-related matters, micro-expressions are widely used to detect deception. In this research, a deep learning model that interprets the changes in the face into meaningful information has been trained using The Facial Expression Recognition 2013 dataset. Necessary data is also obtained through live stream or video stream by detecting via computer vision and evaluating with the trained model. Finally, the data obtained is transformed into graphic and interpreted to determine whether the people are trying to deceive or not. The deception classification accuracy of the custom trained model is 74.17% and the detection of the face with high precision using the computer vision methods increased the accuracy of the obtained data and provided it to be interpreted correctly. In this respect, the study differs from other studies using the same dataset. In addition, it is aimed to facilitate the deception detection which is performed in a complex and expensive way, by making it simple and understandable.
Increased Effect Sizes in a Mindfulness- and Yoga-Based Intervention After Adjusting for Response Shift with Then-Test

Published: March 2023

Abstract

Objectives

Response shift refers to variations in self-reported evaluations at different times from changes in one’s internal standards, values, and meanings. The current study explored the utility of the then-test to detect a potential mindfulness-based response shift occurrence during a mindfulness- and yoga-based intervention for student musicians, and to ascertain to what extent effect sizes could differ when adjusting for it.

Method
Participants (n = 31) completed the Five Facet Mindfulness Questionnaire (FFMQ) halfway through the intervention (Time 1-FFMQ), post-intervention (Time 2-FFMQ), and immediately after Time 2-FFMQ with a then-test approach that asked participants to rate the FFMQ based on retrospective reflections on their mindfulness at Time 1 (then-test-FFMQ). Paired t-tests and Hedges’ g effect sizes were computed to estimate three potential effects: response shift (Time 1-FFMQ minus then-test-FFMQ), the conventional intervention effect (Time 2-FFMQ minus Time 1-FFMQ), and the effect after adjusting for response shift (i.e., actual intervention effect = Time 2-FFMQ minus then-test-FFMQ).

Results
Response shift was significant for the FFMQ Observe subscale (g = 0.41) and total scale (g = 0.37). The adjusted scores in all subscales (Observe, g = 0.47; Describe, g = 0.25; Act Aware, g = 0.40; Non-judge, g = 0.28; Non-react, g = 0.57) and total scale (g = 0.60) achieved significance and yielded larger effect sizes than the conventional results, for which only Act Aware (g = 0.28), Non-react (g = 0.36), and total scale (g = 0.28) were significant.

Conclusions
Notwithstanding some methodological limitations, this study lends support to the utility of the then-test to quantify response shift. When adjusting for it, effect sizes from a mindfulness- and yoga-based intervention were generally amplified.

NEDORT: a novel and efficient approach to the data overlap problem in relational triples
Authors: Zhang Zhanjun , Hu Xiaoru , Zhang Haoyu , Liu Jie 
Published: March 2023

AbstractRelation triple extraction is a combination of named entity recognition and relation prediction. Early works ignore the problem of data overlap when extracting triples, resulting in poor extraction performance. Subsequent works improve the capability of the model to extract overlapping triples through generative and extractive methods. These works achieve considerable performance but still suffer from some defects, such as poor extraction capability for individual triplets and inappropriate spatial distribution of the data. To solve the above problems, we perform sequence-to-matrix transformation and propose the NEDORT model. NEDORT predicts all subjects in the sentence and then completes the extraction of relation–object pairs. There are overlapping parts between relation–object pairs, so we conduct the conversion of sequence to matrix. We design the Differential Amplified Multi-head Attention method to extract subjects. This method highlights the locations of entities and captures sequence features from multiple dimensions. When performing the extraction of relation–object pairs, we fuse subject and sequence information through the Biaffine method and generate relation–sequence matrices. In addition, we design a multi-layer U-Net network to optimize the matrix representation and improve the extraction performance of the model. Experimental results on two public datasets show that our model outperforms other baseline models on triples of all categories
Competition policy in the new wave of global protectionism. Prospects for preserving a fdi-friendly institutional environment
Authors: Mariotti Sergio 
Published: March 2023

AbstractBy its very nature, competition policy has a double face vis-à-vis foreign direct investment (FDI), as it can encourage inflows into the country by ensuring a level playing field for all investors (domestic and foreign), but also be captured and misused to discourage FDI in the name of superior national interests or under pressure from lobbying groups. The worldwide emergence of “global protectionism”, in reaction to the inequalities and imbalances caused by globalization, and the impasse of supranational institutions in the governance of international relations have paved the way for the abuse of competition policy as a barrier to FDI. After giving evidence of these phenomena that threaten economic growth and welfare, the paper discusses prospects for preserving an institutional environment conducive to FDI. A desirable to-do list is outlined.
