Published: October 2024

Introduction
Restless Legs Syndrome (RLS) is a neurological disorder characterized by an urge to move arms and legs, commonly combined with distress, pain and motor restlessness. It can cause fragmented sleep, daytime symptoms, and decreased quality of life. Pharmacological treatment can suppress symptoms, but not cure. When challenged with illness, people may turn to their inner psychological resources such as self-esteem and mastery. The Pearlin Mastery scale was developed to study stress and coping, is commonly used in people with chronic illnesses, however, not yet validated in people with RLS.

Aim
The aim was to test reliability and construct validity of the Pearlin Mastery Scale in persons with RLS.

Methods
A cross-sectional postal survey including the Pearlin Mastery Scale, Restless Legs Syndrome-6 Scale, Pittsburgh Sleep Quality Index and Patient Health Questionnaire was sent out to members (n = 1500) of the national RLS association and 788 (52.5%) agreed to participate. Data were analyzed using classical test theory, Confirmatory factor analysis and Rasch measurement theory analysis. Hypothesis testing for construct validity was done by bivariate correlation analyses.

Results
Most respondents were women (65%), retired (71%) and had a mean-age of 70.8 years (SD 11.4). The 7-item version of the Pearlin Mastery Scale showed poor fit to the one factor model. After omitting the two positively worded items (i.e., item 4 and 6), the 5-item version was found to be unidimensional, with satisfactory internal consistency. However, all items showed considerable ceiling effects. No measurement variance was seen regarding age-groups or sex. Higher level of mastery was moderately correlated with less depressive symptoms but only weakly correlated to RLS-related sleep problems.

Conclusion
The 5-item version of the Pearlin Mastery Scale is suggested to be used in persons with RLS due to its acceptable psychometric properties. The instrument could be applied as an outcome measure for behavioral change interventions aiming to support mastery in RLS.

Gas emissions occurring in the agricultural land of Nglobo Village, Blora Regency, Indonesia, have led to land contamination, resulting in worsened of watershed health over time. The evidence is apparent in the water and soil quality exceeding water quality standard. Consequently, conflicts have arisen in the community due to failed harvests of rice and corn, impacting crops failed. The aim of this research is to restore the health of the contaminated watershed, addressing both agricultural land and water quality. The methodology in this research involves a micro watershed management approach, which includes discussion activities with the community and other parties, remediation efforts, field schools and monitoring and evaluation. The study findings suggest that the addition of organic fertilizers to restore soil fertility, particularly enhancing soil organic carbon, is crucial. This is achieved by applying 29.58 tons/ha to 30.14 tons/ha of fertilizer on the affected land. Post-remediation water quality shows values below the threshold, indicating the health of the Nglobo river basin. The results of the planting test evaluation showed that rice and corn were in good condition, as evidenced by the absence of crop failure, and the fertility of agricultural land could be restored. Micro watershed management approach, of measurable, with real action together with the affected communities and related parties, can resolve social conflicts that occur due to pollution of community agricultural land.

In numerous applications minimizers may not be explicit or even may not exist. In such circumstances, it is crucial to know that the infimum of F can be approximated using a sequence of Lipschitz functions that meet the given boundary conditions.
However, there are instances where this approximation is not feasible, even with polynomial Lagrangians that meet Tonelli’s existence conditions: this situation is referred to as the Lavrentiev phenomenon.
Some results are present in the literature if one requires the Lipschitz approximations to preserve just one endpoint constraint or when the Lagrangian is finite valued.
The present paper deals with problems with two endpoint constraints and Lagrangians that are allowed to take extended values. As a byproduct, our Lipschitz approximations may preserve given state constraints.
The extended-valued case is challenging since the phenomenon may occur even when the Lagrangian is constant on its effective domain, whose topology becomes relevant.
Once assumed that the Lagrangian is radial convex on the rays of the last variable, our findings offer new insights, even when the Lagrangian L is real-valued, autonomous, and there are no state constraints.
On prescribing the number of singular points in a Cosserat-elastic solid
Authors: Hüsken Vanessa 
Published: October 2024

Abstract
In a geometrically non-linear Cosserat model for micro-polar elastic solids,
we prove that critical points of the Cosserat energy functional with an arbitrary large (finite) number of singularities do exist, whereas Cosserat energy minimizers are known to be locally Hölder continuous. To reach that goal, we first develop a technique to insert dipole pairs of singularities into smooth maps while controlling the amount of Cosserat energy needed to do so. We then use this method to force an arbitrary number of singular points into (weak) Cosserat-elastic solids by prescribing smooth boundary data. The boundary data themselves are given in such a way, that they contain no topological obstruction to regularity. Throughout this paper, we often exploit connections between harmonic maps and Cosserat-elastic solids, so that we are able to adapt and incorporate ideas of R. Hardt and F.-H. Lin for harmonic maps with singularities, as well as of F. Béthuel for dipole pairs of singularities.
The Three Forms of Dostoevsky’s Philosophy
Authors: Xu Fenglin 
Published: October 2024

Abstract
Dostoevsky’s novels contain rich and profound philosophical ideas that can be broadly categorized into three forms: moral philosophy, existential philosophy, and tragic philosophy. The core of moral philosophy is the doctrine of love, emphasizing selfless dedication and self-sacrifice. Existential philosophy opposes psychology to reason, declaring the legitimate rights of individual psychological freedom. Tragic philosophy further explores the deep ethical and moral question of whether individuals have the right to oppose the world in critical situations.

Die stásis im Lykischen Bund. Folge eines inneraristokratischen Konkurrenzkampfes?
Authors: Pinazza Rick 
Published: October 2024

Zusammenfassung
Die lykische stásis, deren Anlässe und Ursachen sowie die darauffolgende Epoche der römischen Provinzialisierung stoßen bis heute in der Forschung auf ein nur untergeordnetes Interesse. Dieses Forschungsdesiderat aufgreifend, wird unter Hinzuziehen epigraphischer Quellen sowie durch Zurückgreifen auf einen soziologischen Ansatz gezeigt, dass dem inneren Krieg zuvorderst ein Konflikt innerhalb der lykischen Oberschicht zugrunde lag. Begünstigt durch das Fehlen verbindlicher Kriterien, die eine Zugehörigkeit zur politischen Führungsriege gewährleisteten, führte auch in Lykien die römische Expansion zu einer Verschiebung der Kräfteverhältnisse: Politische Macht hielten fortan nicht mehr die Bürger in Händen, die über das größte ökonomische Kapital verfügten, oder diejenigen, die einen möglichst ausgeprägten aristokratischen Habitus besaßen, sondern jene, die die besten Kontakte zu führenden römischen Amtsträgern aufweisen konnten. Diese Perspektive auf das dysfunktionale Streben nach politischer Macht bildet auch einen Ansatz zur Deutung der Einführung bzw. Umstrukturierung des lykischen Bundesrates: Dessen Zusammensetzung aus ehemaligen Amtsträgern des Bundes – ähnlich wie im Falle des römischen Senats – ermöglichte es einerseits der exklusiven lykischen Aristokratie, ihr Streben nach dauerhafter Herrschaft zu verwirklichen; andererseits besaß diese neue, übergeordnete Instanz durch die Aufnahme aller ehemaliger Amtsträger aber auch integrativen Charakter.
Modelling geoid height errors for local areas based on data of global models
Authors: Savchuk Stepan , Fedorchuk Alina , Marjanska Dorota 
Published: October 2024

Abstract
The development of global geoid models became feasible following the launch of specialised satellite missions. Today, the root mean square deviation of the heights in global models of high degree & order varies from centimetres to decimetres across different countries. In countries where the accuracy of such models is lower, there is potential to enhance their precision by applying specific corrections. This study presents a novel methodology for locally modelling the height errors of high degree & order global geoid models using levelling sub-benchmarks for GNSS stations. The methodology is based on a combination of optimal interpolation methods, filtering, and the concept of data weighting by gravity anomaly differences. The methodology is aimed at creating a hybrid model that aligns with the local characteristics of the geoid (or quasi-geoid) derived from the traditional levelling network. The advantage of this methodology lies in its ability to reduce the residual height errors of the EGM2008 and EIGEN6C4 models to less than 1 cm when using only four control points. Such results exceed the initial values of the systematic height errors of these models by 90–96 %. For the GECO model, the residual errors are around 2 cm, while for the XGM2019e_2159 model, they reach 3 cm. These results indicate that this methodology can be applied to all global models of high degree & order, although its effectiveness may vary depending on the specifics of a particular model.
Markov chain Monte Carlo methods applied to the stochastic inversion of 1D viscoelastic parameters
Authors: Azevedo Juarez S. , Borges Marcio R. 
Published: October 2024

Abstract
The characterization of the subsurface profile properties that are susceptible to liquefaction during earthquakes is of great importance in accident prevention.
Field data can be used in a stochastic inverse problem to estimate the material properties using Markov chain Monte Carlo Methods (McMC) that incorporates prior knowledge about the unknown parameters as well as the data available.
Here, we numerically study the Random Walk (RW) and Differential Evolution (DE) variations of the Metropolis algorithm in the context of seismic modeling considering the viscoelastic wave equation.
The algorithms are tested with data from the 1987 Superstition Hills earthquake recorded at the Wildlife Site.
The results show the effectiveness and accuracy of these algorithms, with emphasis to DE which reached convergence earlier compared to RW.

Waren Österreicher unter nationalsozialistischen Tätern überrepräsentiert?
Authors: Bauer Kurt 
Published: October 2024

Abstract
1966 richtete Simon Wiesenthal ein Memorandum an die österreichische Bundesregierung. In diesem Papier behauptete er – freilich ohne dies empirisch zu untermauern – eine starke Über¬re¬präsentation von Österreichern unter NS-Tätern. Es ging Wiesenthal darum, verstärkte Be-mü¬hungen zur Strafverfolgung belasteter Personen in Österreich zu bewirken. Das gelang ihm nicht. Allerdings setzte sich Wiesenthals These von der österreichischen Überrepräsentation in der Wissenschaft und Publizistik durch und zog sich wie ein roter Faden durch die Fachliteratur und populärhistorische Darstellungen. In dem vorliegenden Beitrag überprüft und bewertet Kurt Bauer anhand der Analyse verschiedener Tätergruppen und Tatkomplexe die Validität dieser Aussage. Er kommt zu dem Ergebnis, dass der Anteil an Österreichern unter NS-Tätern ungefähr dem Bevölkerungsanteil der sogenannten Ostmark am Deutschen Reich entsprach.
„Ein Stachel im Fleisch der Christdemokraten“
Authors: Preißler Josefine 
Published: October 2024

Abstract
Das Studienzentrum Weikersheim (SZW) ist heute weitgehend vergessen, obwohl es ein wichtiger Stichwortgeber im politischen Diskurs um die sogenannte geistig-moralische Wende war. 1979 auf Initiative von Hans Filbinger und Günter Rohrmoser gegründet, verstand sich das SZW als „Stachel im Fleisch der Christdemokraten“, für die es konservative Denkimpulse liefern wollte. Auf der Basis weitgehend neu erschlossener Quellen zeichnet Josefine Preißler die Gründung und Entwicklung des Studienzentrums bis zum Jahr 1985 nach. Sie führt aus, warum dessen Ideen kaum Eingang in die Politik der christlich-liberalen Regierung unter Helmut Kohl finden konnten, und zeigt auf, inwiefern dieses Enttäuschungsmoment zur Radikalisierung des SZW führte, das fortan einen zentralen Ort im „Brückenspektrum zwischen Konservativismus und Rechtsextremismus“ (Armin Pfahl-Traughber) bildete.
Wilhelm Treue und der Weg zur „Geschichtlichen Darstellung der gewerblichen Wirtschaft“
Authors: Roelevink Eva-Maria 
Published: October 2024

Abstract
Der Historiker Wilhelm Treue (1909–1992) gilt als prägende Figur für die Konstituierung der Unternehmensgeschichte in Westdeutschland nach dem Zweiten Weltkrieg. Eva-Maria Roelevink unternimmt den Versuch, den bisher rein auf Treues Veröffentlichungen begrenzten Wissensstand quellenfundiert und insbesondere für die Zeit vor 1945 zu erweitern. Auf diese Weise lässt sich zeigen, dass sein vermeintlich gebrochener Karriereverlauf ausschlaggebend für seine Konzeption einer modernen Unternehmensgeschichte war. Treue wechselte gezwungenermaßen von der Universität in die amtliche Militärgeschichtsschreibung; hier entwickelte er seine spätere Konzeption und von hier aus knüpfte er die Netzwerke in die Wirtschaft, von denen er nach 1945 erheblich profitierte.

Published: October 2024

Abstract
In the present work, one of the leading health issues i.e. cancer was targeted by synthesizing and biologically investigating the potential of pyrazine-based thiazolidinone derivatives (1–13). The basic structure of the synthesized compounds was determined using a variety of spectroscopic techniques, including 1H NMR, 13C NMR, and HREI-MS. These scaffolds were studied for their biological profiles as anti-cancer as well as anti-urease agents. The biological effectiveness of these compounds was compared using the reference tetrandrine (IC50 = 4.50 ± 0.20 µM) and thiourea (IC50 = 5.10 ± 0.10 µM), respectively. Among novel compounds, scaffold 3, 6, 7 and 10 demonstrated an excellent potency with highest inhibitory potential (IC50 = 1.70 ± 0.10 and 1.30 ± 0.20 µM), (IC50 = 4.20 ± 0.10 and 5.10 ± 0.30 µM), (IC50 = 2.10 ± 0.10 and 3.20 ± 0.20 µM) and (IC50 = 2.70 ± 0.20 and 4.20 ± 0.20 µM), respectively, out of which scaffold 3 emerged as the leading compound due to the presence of highly reactive –CF3 moiety which interacts via hydrogen bonding. Molecular docking investigations of the potent compounds was also carried out which revealed the binding interactions of ligands with the active sites of enzyme. Moreover, the electronic properties, nucleophilic and electrophilic sited of the lead compounds were also studied under density functional theory (DFT).

Artisanal and small-scale gold mining has commonly used the mercury amalgamation method for gold ore extraction. The processing waste or tailings often contain gold and other metals. This study examined the effects of cow manure amendment and the ratio of gold mine tailings on sweet potato (Ipomoea batatas L.) gold phytomining. The pot experiment was conducted in the Faculty of Agriculture greenhouse at Padjadjaran University in Indonesia. The sweet potato MZ119 clone (an orange-fleshed sweet potato) was planted on a polybag (40 x 40 cm) consisting of 10 kg of planting media, which was a mixture of gold mine tailing and soil. The design used was a completely randomized design factorial with three replications. The first factor was ratios of gold mine tailing consisting of three levels, namely 30%, 50%, 70%, and 100% (w/w). The second factor was doses of organic manure, namely without cow manure, 250 g pot-1, 500 g pot-1, and 750 g pot-1. The results demonstrated that the application of cow dung and the gold mine tailings ratio (w/w) had a significant (p = 0.05) effect on plants' dry weight biomass, gold accumulation, and gold phytomining by sweet potato. The highest gold mass yield of 0.066 mg gold plant-1 was achieved by a 50% (w/w) gold mine tailing ratio and 750 g pot-1 cow manure treatment.

Published: October 2024

Limestone mining removes topsoil and produces overburden piles, which is improper for plant growth. The objectives of this study were to compare the texture, certain chemical properties, and bacterial population of overburden to the topsoil and to observe the effects of compost amendment on the growth of corn seedlings on the potted overburden. The overburden characterization was performed using a quantitative descriptive method with purposive sampling. Samples were taken from a 6-month-old overburden pile and a pine-vegetable agroforestry ecosystem. The data were further analyzed by using the Student’s t-test. A bioassay was set up in a randomized block design with various concentration compost treatments and five replications. The results showed significant differences between texture, chemical characteristics, and bacterial counts of overburden and topsoil were recorded. The topsoil was more acidic and had higher organic carbon, potential phosphorus, potential potassium, and cation exchange capacity, while the overburden had higher levels of calcium; however, the total N and Magnesium content in topsoil and overburden was similar. The bacterial population of the overburden was lower than in the topsoil. A total of 16 gram-negative and one gram-positive bacteria have been identified from both samples. Applying huge amounts of compost enhanced corn seedlings' growth in the overburden. The study suggested that overburden was more unfertile compared to the topsoil. Therefore, the improvement of overburden properties by compost amendment is needed to green the area.
Split Genders: Medical versus Legal Understanding of Gender Identity (De Lege Lata and De Lege Ferenda)
Authors: Bielska-Brodziak Agnieszka , Gawlik-Starzyk Aneta , Jakubowski Tomasz , Trofimiuk-Müldner Małgorzata 
Published: October 2024

Abstract
For centuries, the law accepted the legal gender of an individual that was indicated at birth by the appearance of their genitalia and stated on their birth certificate. Nowadays, however, we have plenty of scientific, medical and psychological evidence (and thus reasons) to revise the adopted way of thinking about legal gender to associate it more with gender identity. Most people do not perceive a potential conflict between genital sex and gender identity, because their genital sex is consistent with their gender identity. Trans- and intersex comunnity needs recognition of their gender identity independent of their genital sex as a condition for a life of self-determination, personal freedom, respect and dignity; these are, aft er all, values that are extremely important for the law. The purpose of this analysis is to determine whether the concept of gender identity is perceived generally in the Polish language and the Polish legal system in a way that takes into account current medical knowledge and the legitimate needs of the individual. If not, then what de lege ferenda recommendations can be made to change this situation?
