Extractive Bargains and the State-Society Nexus: One World, Many Bargains
Authors: Bowles Paul , Andrews Nathan 
Published: September 2023

AbstractStates have historically sought to position (sometimes re-imagine) extractive activities as presenting an opportunity for broader societal goals to be met. This positioning typically entails the need to convince social actors that the continuation of resource extraction is beneficial despite the increasing recognition of its socio-environmental costs and the growing resistance to extractivism globally. This act or process of seeking societal acceptance for the state’s preferred extractive policies in exchange for delivering on wider societal goals is what we define as ‘extractive bargains’. Informed by this central conceptualization, this chapter offers a novel approach to exploring such bargains within the spectrum of both analytical and normative ideal types. To provide further empirical grounding, we give an initial account of cases from the Global South and Global North that exemplify the different types of analytical and normative bargains operating at the state-society interface. We also briefly explore those that appear to lie outside of this level of analysis.

AbstractIn this chapter, we study the single-particle longitudinal dynamics of SSMB. The motivation is to answer the question: how to realize the short bunch length and small longitudinal emittance in an electron storage ring, as required by SSMB?

Zusammenfassung
Ziel der Arbeit
Analyse der Häufigkeit einer zerebralen Amyloidangiopathie (CAA) bei Patientinnen mit kognitiven Störungen und der Häufigkeit einer Koinzidenz von gerinnungshemmender Therapie und CAA. Explorative Analyse von Zusammenhängen zwischen Antikoagulation und CAA-typischer Läsionslast in der MRT.

Material und Methoden
Patientinnen mit subjektiver kognitiver Störung (SCD), amnestischem und nichtamnestischem MCI (aMCI/naMCI), Alzheimer-Demenz (AD), gemischter Demenz (MD) und vaskulärer Demenz (VD) aus einem universitären Demenzzentrum, die sich von 02/2016 bis 12/2020 erstmals zur Demenzdiagnostik vorgestellt hatten, wurden in diese retrospektive Analyse eingeschlossen. Im Rahmen der Diagnostik erfolgten eine kranielle MRT inkl. Gradientenechosequenz und die Erfassung CAA-spezifischer MRT-Biomarker. Im Rahmen der retrospektiven Aktendurchsicht wurde das Vorliegen einer gerinnungshemmenden Medikation mit Thrombozytenaggregationshemmern, direkten oralen Antikoagulanzien (DOAK) oder Vitamin-K-Antagonisten zum Zeitpunkt der Vorstellung ermittelt.

Ergebnisse
Im Beobachtungszeitraum von 02/2016 bis 12/2020 wurden 458 Patientinnen (209 männlich, 249 weiblich, Durchschnittsalter 73,2 ± 9,9 Jahre) mit SCD (n = 44), naMCI (n = 40), aMCI (n = 182), AD (n = 120), MD (n = 68) und VD (n = 4) analysiert. Bei 109 Patientinnen (23,8 %) lagen die MR-Kriterien einer möglichen oder wahrscheinlichen CAA vor. Die CAA-Prävalenz war am höchsten bei Patientinnen mit aMCI (39,4 %) und MD (28,4 %). Bei 30,3 % der Patientinnen mit möglicher oder wahrscheinlicher CAA bestand eine Thrombozytenaggregationshemmung, bei 12,8 % eine DOAK-Therapie und bei 3,7 % eine Therapie mit Vitamin-K-Antagonisten. Die Anzahl kortikaler und subkortikaler Mikroblutungen war insgesamt bei Patientinnen mit gerinnungshemmender Therapie höher als bei Patientinnen ohne Gerinnungshemmung (p = 0,047). Ein Zusammenhang zwischen gerinnungshemmender Therapie und Häufigkeit kortikaler superfizieller Siderosen bildete sich nicht ab (p = 0,634).

Diskussion
Die CAA ist bei Patientinnen mit kognitiven Störungen häufig. Bei nahezu der Hälfte der Patientinnen mit CAA besteht eine gerinnungshemmende Medikation. Eine gerinnungshemmende Medikation ist mit einer größeren Anzahl kortikaler und subkortikaler Mikroblutungen vergesellschaftet.

AbstractPurposeTo define the prevalence of Central Sensitization (CS) in patients with Anterior Knee Pain (AKP) and determine whether there is an association between CS and the magnitude of pain, disability, quality‐of‐life and psychological impairment.MethodsThe data of a total of 44 AKP female patients with a mean age of 27.7 years (15–50) recruited consecutively from hospital outpatient knee clinics were prospectively included in this study. The patients had no antecedents of knee trauma or surgery and no history of injury or disease of the nervous system. There were also 50 healthy female controls with a mean age of 26.1 years (16–46). CS was evaluated using the Central Sensitization Inventory (CSI). Quality‐of‐life was evaluated using the EuroQoL‐5D questionnaire. Self‐reporting of clinical pain intensity was obtained using the Visual Analogue Scale. The Kujala Knee Scale and IKDC form were used to evaluate disability. Anxiety and depression were evaluated using the Hospital Anxiety and Depression Subscale (HAD). Kinesiophobia was measured with the Tampa Scale for Kinesiophobia (TSK‐11) and catastrophizing by means of the Pain Catastrophizing Scale (PCS).ResultsSixteen AKP patients (36%), and 2 (4%) of the healthy controls presented with central sensitization (p < 0.01). AKP patients with CS have a greater degree of disability based on the Kujala Scale and higher levels of anxiety and depression than AKP patients without CS. The score of AKP patients in the CSI correlated weakly with disability and quality of life and moderately with anxiety and depression. However, no association was seen between CSI score and pain intensity, nor with catastrophizing and kinesiophobia. A multivariate logistic regression analysis showed that only depression was statistically significant in the prediction of the presence of CS (odds ratio 1.45; 95% CI 1.07 to 1.96).ConclusionsAKP patients have a significantly higher prevalence of CS in comparison with what has been reported for the general population. This finding suggests the presence of altered pain modulation in a subgroup of AKP patients.Level of evidenceLevel III.

AbstractThe exposure to smoking related products has been evaluated through urine illness risk marker determination through the analysis of urine samples of smokers and vapers. Biomarkers and their metabolites such as N-acetyl-S-(2-cyanoethyl)-L-cysteine (CEMA), N-acetyl-S-(3,4-dihydroxybutyl)-L-cysteine (DHBMA), N-acetyl-S-[1-(hydroxymethyl)-2-propen-1-yl)-L-cysteine (MHBMA), N-acetyl-S-(3-hydroxypropyl)-L-cysteine (3HPMA), 2R-N-acetyl-S-(4-hydroxybutan-2-yl)-L-cysteine (HMPMA), and N-acetyl-S-(3-carboxy-2-propyl)-L-cysteine (CMEMA) together with nicotine and cotinine were identified and quantified by LC-HRMS and LC-MS/MS, and data found normalized to the creatinine level. One hundred two urine samples were collected from smokers, non-smokers, and vapers, spanning an age range from 16 to 79 years. Results obtained showed that CEMA was only detected in urine samples from smokers and MHBMA was in the same order of magnitude in all the urine samples analyzed. HMPMA was found in the urine of vapers at the same order of concentration as in non-smokers. 3HPMA in vapers was lower than in the urine of smokers, presenting an intermediate situation between smokers and non-smokers. On the other hand, DHBMA in vapers can reach similar values to those found for smokers, while CMEMA shows concentrations in the urine of vapers higher than in the case of non-smokers and traditional smokers, requiring new research to link this metabolite to the use of electronic cigarettes and possible alternative metabolomic routes. In general, this study seems to verify that traditional smoking practice constitutes a major source of carcinogenic chemicals compared with substitutive practices, although those practices are not free of potential harm.

Within-individual changes in physical work demands associated with self-reported health and musculoskeletal symptoms: a cohort study among Dutch workers
Authors: Cillekens Bart , van Eeghen Emma , Oude Hengel Karen M. , Coenen Pieter 
Published: September 2023

Abstract
Purpose
This study aimed to investigate changes in physical work demands in association with self-rated health and musculoskeletal symptoms.

Methods
Data from five waves over the period 2019–2021 of the Netherlands Working Conditions Survey COVID-19 were available for 7191 participants aged 19–64 years who worked (partly) on-site during at least two consecutive waves. Logistic generalized estimated equations (GEE) were used to estimate the odds ratios (OR) with 95% confidence interval (CI) for changes (increase or decrease compared to no change) in physical work demands between two waves and poor self-rated health and musculoskeletal symptoms in the following wave, adjusted for the health outcome at the first wave, age, educational level, working hours and hours worked from home.

Results
In females, a statistically significant association was found between an increase in physical work demands compared to no change and musculoskeletal symptoms (OR 1.39, 95% CI 1.17–1.65). A decrease in physical work demands in females was not statistically significantly associated with musculoskeletal symptoms (OR 0.93, 95% CI 0.80–1.08). Similar trends were found for poor self-rated health, although non-statistically significant. For males, comparable but attenuated associations were found.

Conclusion
While our study showed that increasing physical work demands are associated with adverse health (self-reported and musculoskeletal), it did not appear to benefit worker’s health to reduce work demands. Future research with multiple measurements in a shorter period and additionally using devices to measure physical work demands will be needed to confirm our study results.

Abstract
Introduction
Early detection of severe complications may reduce morbidity and mortality in patients undergoing hepatic resection. Therefore, we prospectively evaluated a panel of inflammatory blood markers for their value in predicting postoperative complications in patients undergoing liver surgery.

Methods
A total of 139 patients undergoing liver resections (45 wedge resections, 49 minor resections, and 45 major resections) were prospectively enrolled between August 2017 and December 2018. Leukocytes, CRP, neutrophil-lymphocyte ratio (NLR), thrombocyte-lymphocyte ratio (TLR), bilirubin, INR, and interleukin-6 and -8 (IL-6 and IL-8) were measured in blood drawn preoperatively and on postoperative days 1, 4, and 7. IL-6 and IL-8 were measured using standardized immunoassays approved for in vitro diagnostic use in Germany. ROC curve analysis was used to determine predictive values for the occurrence of severe postoperative complications (CDC ≥ 3).

Results
For wedge and minor resections, leukocyte counts at day 7 (AUC 0.80 and 0.82, respectively), IL-6 at day 7 (AUC 0.74 and 0.73, respectively), and CRP change (∆CRP) at day 7 (AUC 0.72 and 0.71, respectively) were significant predictors of severe postoperative complications. IL-8 failed in patients undergoing wedge resections, but was a significant predictor of severe complications after minor resections on day 7 (AUC 0.79), had the best predictive value in all patients on days 1, 4, and 7 (AUC 0.72, 0.72, and 0.80, respectively), and was the only marker with a significant predictive value in patients undergoing major liver resections (AUC on day 1: 0.70, day 4: 0.86, and day 7: 0.92). No other marker, especially not CRP, was predictive of severe complications after major liver surgery.

Conclusion
IL-8 is superior to CRP in predicting severe complications in patients undergoing major hepatic resection and should be evaluated as a biomarker for patients undergoing major liver surgery. This is the first paper demonstrating a feasible implementation of IL-8 analysis in a clinical setting.

The duals of the subfield codes are also investigated and found to be almost optimal with respect to the sphere-packing bound. In addition, the covering structure for the studied subfield codes is determined. Some of these codes are found to have the important property that any nonzero codeword is minimal, which is a desirable property that is useful in the design of a secret sharing scheme based on a linear code. Moreover, a specific example of a secret sharing scheme based on one of these subfield codes is given. Finally, a class of optimal two-weight linear codes over $${\mathrm{I\!F}}_q$$

Furthermore, it is shown that these optimal codes can be used to construct strongly regular graphs.

Die Zukunft der Prüfung und Entwicklung flexibler Steinschlagschutzsysteme am Prüf- und Forschungszentrum Erzberg
Authors: Heiss Christian A. 
Published: September 2023

ZusammenfassungBausätze flexibler Steinschlagschutzsysteme sind Bauprodukte, die unter das Regime der EU-Bauprodukteverordnung fallen und dadurch bestimmte Leistungskriterien erfüllen müssen, bevor sie am Europäischen Binnenmarkt CE-gekennzeichnet vertrieben werden dürfen. Zur Leistungsbewertung bzw. um Auskunft über „Wesentliche Merkmale“ des Produkts geben zu können, muss ein Bausatz standardisierten Systemerstprüfungen im Maßstab 1:1 unterzogen werden. Diese sehr kostenintensiven Prüfungen liefern zwar in einem gewissen Bereich die Möglichkeit, Systeme miteinander zu vergleichen, eignen sich aber nur bedingt für die Weiterentwicklung derartiger Systeme und deren Bemessung und konstruktiven Gestaltung im Gelände. Der Lehrstuhl für Bergbaukunde, Bergtechnik und Bergwirtschaft an der Montanuniversität Leoben hat in den vergangenen Jahren durch die erfolgreiche Übertragung der standardisierten Prüfverfahren und eines handelsüblichen flexiblen Steinschlagschutzsystems in den Labormaßstab Möglichkeiten aufgezeigt, wie das Leistungsvermögen derartiger Systeme detailliert und gleichzeitig kostengünstig untersucht und dadurch eine umfangreiche Datenbasis für die nummerische Simulation flexibler Steinschlagschutzsysteme geschaffen werden kann. Im von der FFG geförderten Projekt NAGEMA (Naturgefahrenmanagement) werden von der Trumer Schutzbauten GmbH in enger Zusammenarbeit mit der Montanuniversität Leoben die Erkenntnisse der Systemmodellierung im Labormaßstab für die Errichtung einer neuen Schrägwurfanlage umgesetzt, sodass am Steirischen Erzberg zukünftig flexible Steinschlagschutzsysteme auch im 1:1 Maßstab effektiver und effizienter geprüft werden können.
Time-optimal trajectory planning for a rigid formation of nonholonomic mobile platforms
Authors: Schmidt Simon , Gattringer Hubert , Mueller Andreas 
Published: September 2023

AbstractThis paper presents a method for planning time-optimal trajectories for a formation of multiple nonholonomic (heavy duty) platforms (HDPs) to cooperatively transport an object to a specified pose. The first part addresses the mobile platforms themselves while the second part provides a trajectory planning approach derived from the well-known virtual leader approach. In order to ensure proper transport of the shared payload, the vehicles are modeled individually, resulting in a formation control problem. The goal of the optimization process is to minimize a cost function that balances time optimality, smooth control signals, and formation rigidity. The optimal control problem (OCP) takes into account the kinematics of the vehicles as well as their physical limitations. It is solved by using a multiple shooting method, which yields the desired trajectories for all vehicles while ensuring smooth control signals. The paper includes optimization results for several scenarios involving two and three HDPs together with various target poses, demonstrating the effectiveness of the proposed method.

AbstractCovid-19 crisis did hit many socio-economic aspects in the whole world. In the scientific research, the problem is getting even worse, since most of materials and consumable are allocated to the health sector. Many research laboratories around the world have big delay in receiving their purchases to accomplish their research projects. In the developing countries, the situation is much more difficult, since most of the funding resources are directed to the Covid-19 crisis and there is a notable increase in reagents’ prices. Therefore, the aim of the present study is to make a homemade reagents for RNA purification from eukaryotic cells/tissues. The homemade phenol-based RNA extraction reagents were prepared using saturated phenol pH 4.3 (adjusted by 0.5 M citrate buffer) and guanidine thiocyanate. To validate the phenol-based reagent, RNA was purified from different biological samples (cell line, tissues, and fungi) using homemade phenol-based versus a commercial one. Concentration of RNA samples extracted from the same number of cells were compared to assess the homemade preparation of phenol-based reagent. In conclusion, homemade phenol-based reagent is cost effective and comparable to the commercial one. Using homemade phenol-based, RNA extraction was successfully purified from different biological sources.

Published: September 2023

AbstractThe synthetic control method (SCM) represents a notable innovation in estimating the causal effects of policy interventions and programs in a comparative case study setting. In this paper, we demonstrate that the data-driven approach to SCM requires solving a bilevel optimization problem. We show how the original SCM problem can be solved to the global optimum through the introduction of an iterative algorithm rooted in Tykhonov regularization or Karush–Kuhn–Tucker approximations.
Additive Effect, Feasibility, and Cost-Effectiveness of Family Engagement Activities that Supplement Dual Language Preschool Instruction
Authors: Spencer Trina D. , Kirby Megan S. , Garcia Anna R. , Sturm Becca 
Published: September 2023

Abstract
There are several benefits for Dual Language Learners (DLLs) when their home language is integrated into classroom instruction. For example, instruction in students’ home language facilitates the learning of the new language more rapidly and supports bilingualism. One way to enhance young children’s language learning is to engage families in home language activities that reinforce dual language instruction provided at school. The primary purpose of this study was to examine the extent to which Spanish family engagement activities (FEAs) increased the effect of dual language instruction on the English and Spanish vocabulary and narrative skills of preschoolers. In addition, we also report on the feasibility and cost-effectiveness of Spanish FEAs used to boost young children’s dual language learning. With support from researchers, four Head Start teaching teams delivered multitiered dual language instruction in their classrooms. This involved English large group instruction twice a week and alternating Spanish and English small group intervention with a subset of students 4 times a week. Half of the children who received small group intervention (n = 11) were randomly assigned to also receive the caregiver-implemented FEAs in Spanish in addition to classroom dual language instruction. In a small-scale randomized pre-posttest group study, we examined the additive effect of the FEAs on children’s narrative and vocabulary in English and Spanish. After controlling for pretest scores, the FEAs showed a significant effect on Spanish vocabulary, but not narrative skills. Caregivers reported that they enjoyed the FEAs and would continue using them. The cost-effectiveness analysis revealed that benefits to DLLs’ Spanish vocabulary can be achieved at a reasonable cost.
