INTRODUCTION:

Despite growing awareness of post–coronavirus disease 2019 (COVID-19) cholangiopathy as one of the most serious long-term gastrointestinal consequences of COVID-19, the endoscopic features of this disease are still poorly characterized. This study aimed to more precisely define its endoscopic features and to outline the role of endoscopic retrograde cholangiopancreatography (ERCP) in the management of this entity.

METHODS:

In this observational study, 46 patients with confirmed post–COVID-19 cholangiopathy were included.

RESULTS:

Based on the endoscopic features observed in 141 ERCP procedures, post–COVID-19 cholangiopathy can be classified as a variant of secondary sclerosing cholangitis in critically ill patients. It appeared early in the course of intensive care treatment of patients with COVID-19 (cholestasis onset 4.5 days after intubation, median). This form of cholangiopathy was more destructive than stricturing in nature and caused irreversible damage to the bile ducts. A centripetal pattern of intrahepatic bile duct destruction, the phenomenon of vanishing bile ducts, the absence of extrahepatic involvement, and the presence of intraductal biliary casts (85% of patients) were typical cholangiographic features of post–COVID-19 cholangiopathy. This cholangiopathy was often complicated by small peribiliary liver abscesses with isolation of Enterococcus faecium and Candida spp. in bile culture. The prognosis was dismal, with a 1-year liver transplantation–free survival rate of 44%. In particular, patients with peribiliary liver abscesses or destruction of the central bile ducts tended to have a poor prognosis (n.s.). As shown by multivariate analysis, bilirubin levels (on intensive care unit day 25–36) negatively correlated with liver transplantation–free survival (hazard ratio 1.08, P < 0.001). Interventional endoscopy with cast removal had a positive effect on cholestasis parameters (gamma-glutamyl transpeptidase, alkaline phosphatase, and bilirubin); approximately 60% of all individual values decreased.

DISCUSSION:

Gastrointestinal endoscopy makes an important contribution to the management of post–COVID-19 cholangiopathy. ERCP is not only of great diagnostic and prognostic value but also has therapeutic value and therefore remains indispensable.
COLLECTIVE HABITUATION TO ATTACH BELIEFS OF INDIGENOUS COMMUNITIES IN VILLAGE-OWNED ENTERPRISE (BUMDes) ROUTINES
Authors: Rozuli Ahmad Imron
Published: October 2023

This article serves to present a different perspective about Village-Owned Enterprise (BUMDes), that sustainable BUMDes needs touches of structural and religious values that adhere to communities. The strength of BUMDes is not on the regulation from the village authority. Further, the core values of religious beliefs and community structure renovate the implanted BUMDes knowledge to a referral guideline to behave amidst the communities. A qualitative research approach was applied in the form of a descriptive case study, located in Kutuh Village, Badung Regency, North Bali. The research indicated that the powerfulness of Tri Hita Karana signified beliefs and ancestral values as cultural and symbolic capitals concerning environment, community, and divinity. In this context, three sorts of lands as resources were developed by agents, especially traditional leaders and their apparatus. They were able to restructure customary laws concerning activities. Furthermore, the agents and structure were also able to regulate the conducts of the indigenous people as the roots of mind-shaping for the local people. This was the reason why beliefs could attach to the structure of thought of the indigenous people so that any activities in BUMDa (Bagha Utsaha Manunggal Desa Adat/Traditional Village Integrated Business Entity) can be collectively habituated as routines.

Published: October 2023

This study explains how the AtQ, Garut Islamic boarding school and Mf H, Tasikmalaya Islamic boarding school approachs education through ecotheology which is carried out in response to the environmental crisis. The case boarding schools studied contained two environmental leadership and ecomodernity movements as well as santri pioneering in strengthening the local economy which had a different type. This study took two case boarding schools in West Java, namely the AtQ Ecology Islamic Boarding School, Garut and the MfH Islamic Boarding School, Tasikmalaya. This study aims to describe the process of leadership formation, resource mobility in the environmental movement which is integrated with strengthening the local economy in both Islamic boarding schools andthe role of santri alumni who have returned to the rural society. This study was conducted using a qualitative approach with a grounded theory method that is oriented to data from in-depth interviews, supported by field observations, documentation studies and literature studies. Result the research indicated that the environmental leadership of santri alumni was conduct from the tradition of Islamic ecotheology education in pesantren. The environmental movement carried out by pesantren is by utilizing a network of actors from various parties in mobilizing resources. Ecomodernity in the two pesantren has a different style. This is reflected in the alumni activities of AtQ, Garut students as pioneers of the environmental movement and local economic empowerment in the rural society through environmental education tours and advocacy. Meanwhile, the alumni of MfH students, Tasikmalaya, carry out da’wah on organic agriculture through the millennial santri farmer program and the agribusiness madrasa program.
THE LIFE OF THE NIQAB AND SIRWAL; Phenomenological Study of Family Power Relations to Stigma
Authors: Mohammad Maulana Iqbal
Published: October 2023

This research departs from the widespread stigmatization experienced by those who wear the niqab and sirwal. Society views this attribute negatively because one of them is the actions of terrorists, suicide bombers and others, who carry out their actions using a niqab or sirwal. So this study aims to explore the experiences of the niqab and sirwal users in the private sphere, such as the family and the public sphere in society. To see these two contexts, this study uses the perspective of power relations theory from Michel Foucault and the Stigma concept from Erving Goffman. Meanwhile, methodologically, this study uses a qualitative approach to explore the experiences of the niqab and sirwal users. The findings in this study are that women who wear the niqab in power relations with their parents experience discrimination and social control regarding their attributes. In contrast to sirwal users, who are more liberated by their families in using attributes. Meanwhile, in the public sphere, niqab women again experienced verbal harassment from the public, unlike sirwal, who never experienced harassment. In this case, a woman wearing a niqab is verbally abused not only because she wears a niqab but because she is a woman who is considered inferior in a patriarchal society. In addition, in this case, niqab women experience double discrimination in private and public spaces.

Religious conflicts in the social dynamics of society can still be found in several areas, one of which is the chapel closing event that occurred in Dau, Malang Regency. Communities in the neighborhood reject any activity or activity that using a place of worship, the Boniface Chapel. The conflict occurred as a result of a conflict between residents around the location who did not worship in the Boniface Chapel or people of other religions, and a minority group, that are local residents who worshiped in the chapel. The conflict escalated when it was forced to close and stop all activities at the chapel, since 2018 until now. There are strategic steps taken by various parties, in order to resolve the conflict. One form of conflict resolution adopted in this study is a transformation conflict and a conflict resolution strategy. This strategy will be revealed in this study using a qualitative method, a case study approach. The study began with data collection, which was carried out by means of interviews and field observations. The data that has been collected is then analyzed for presentation. The results of this study are (1) the main core forms of religious conflict in Dau, Malang Regency, and (2) conflict resolution strategies, especially those carried out by minority groups.

Pengaruh Peran Guru dan Gaya Pengasuhan Orang Tua Terhadap Pembentukan Karakter Siswa: Sebuah Studi Kuantitatif
Authors: Sumartini Sri
Published: October 2023

This study aimed to investigate the influence of teacher roles and parenting styles on student character formation at Madrasah Ibtidaiyah Negeri 2 Sleman Yogyakarta using a quantitative associative research method. Multiple linear regression analysis showed that both factors significantly influenced student character formation, with parenting style having a higher contribution than teacher roles. Therefore, a balanced approach between education at home and school is necessary to support good character formation among students. The resulting multiple linear regression equation was Y = 14.047 + 0.497X1 + 0.910X2, with a determination coefficient of 55.9%. Parenting style contributed more (?= 0.910) than teacher roles (?= 0.497) by 58.87%. However, the study had limitations, such as focusing on one school and specific geographical context. Therefore, it is recommended to conduct similar studies in different schools and regions and explore other factors that may influence student character formation.
Industrial Design of Yarn Speed Monitoring System in Positive Feed Circular Knitting Machine
Authors: Momeni Heravi Mohammad Ehsan
Published: October 2023

As constant yarn feeding tension is essential in the formation of uniform stitches, the lack of a monitoring system in a circular weft knitting machine capable of measuring the uniformity of the yarn feeding speed in different driven belts and comparing the feeding rate during the knitting process has led to the use of experimental methods which are dependent on skilled operators. Additionally, in the case of any defects, the equalisation is done by the operator using the trial-and-error method, which consequently increases the risk of human error. Considering the importance of a uniform adjustment of yarn feeding speed on the quality of final fabrics, a monitoring system for measuring and reporting yarn feeding speed was designed. Following its installation on a circular weft knitting machine, the performance of the system in an industrial environment was evaluated. A comparison with the traditional system proved the functionality of the designed automation process. The current study highlights the characteristics of an appropriate sensor, the applicable installation place and direct data reception without intermediaries.

Authors: Cantika Indah Permata , Zulfikar Muhammad Ali , Rusli Handajaya
Published: October 2023

Biodiesel is an alternative fuel that can be easily produced through transesterification with the assistance of a catalyst. Palm oil is a widely utilized feedstock for biodiesel production due to its abundant availability. In this study, a catalyst was synthesized using chitosan (CS) modified with ethylenediamine (EDA) and cross-linked with epichlorohydrin (ECH) for a catalyst heterogeneous in transesterification reaction. The resulting product (CS/EDA/ECH) was characterized using Fourier-transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). Its performance was evaluated for biodiesel production. The CS/ECH/EDA catalyst achieved optimal reaction conditions with 5% EDA concentration at room temperature, an oil: methanol ratio of 1:1 (v/v), a total volume of 10 mL of oil and methanol, and a catalyst mass of 0.75 grams. The methyl esters formed corresponded to the fatty acid content in palm kernel, namely methyl palmitate, methyl 9,10-octadecadienoate, methyl oleate, methyl 12,13-tetradecadienoate, and methyl stearate with the highest methyl ester conversion is methyl oleate. The CS/ECH/EDA catalyst exhibited consistent performance after three use cycles.
Foot Care among Diabetes Patients: A Concept Analysis
Authors: Parliani Parliani , Rungreangkulkij Somporn , Nuntaboot Khanitta
Published: October 2023

Background: The concept analysis of “foot care” is essential for expanding the nursing knowledge base, synthesizing a broader theoretical concept, and guiding more effective care for diabetes patients with and without diabetic foot ulcers (DFU). Foot care in nursing has not yet been comprehensively defined for nurses and other healthcare professionals.Purpose: This concept analysis aimed to elucidate the nursing practice concept of foot care. The study identified surrogate terms associated with the concepts, attributes, antecedents, and consequences by employing Rodger’s evolutionary method in a critical analysis of the relevant literature.Methods: This research used Rodger’s evolutionary analysis. The databases were PubMed (n=188), ProQuest (n=4,790), ScienceDirect (n=292), and Google Scholar (n=7,810) with a total of 13,080 articles identified in this study. The screening process involved evaluating titles and abstracts, followed by a thorough analysis of inclusion criteria, which included full-text articles and the presence of keywords: foot care, diabetes, diabetic foot ulcer. Articles that did not provide a clear definition of foot care were excluded. A total of 45 articles were included. Rodger’s evolutionary analysis stressed inductive investigation and careful analysis of the concept.Results: The results of the foot care concept analysis were: (1) among people with diabetes without DFU, the attributes were foot screening and foot examination, while the antecedents were high glycemic levels, inability of the pancreas to produce insulin, abnormal foot skin condition, and foot-related behaviors; (2) among patients with DFU, the attributes were foot intervention and education, while the antecedents included foot self-care knowledge, motivation, and family and social support. The consequences associated with the concept of foot care included improvement in self-efficacy, quality of life, and self-care behavior.Conclusion: Nurses can use the findings of this foot care analysis in their clinical work by promoting and practicing foot care as a preventative measure that shields patients from ulcers. Additionally, nurses can intervene when patients already have ulcers and provide appropriate wound care. Foot examinations become more manageable when specific practice guidelines are available for diabetes patients.
Barriers and Support for Family Caregivers in Caring for Older Adults with Dementia: A Qualitative Study in Indonesia
Authors: Widyastuti Rita Hadi , Sahar Junaiti , Rekawati Etty , Kekalih Aria
Published: October 2023

Background:  Understanding the barriers and support that family caregivers face when caring for older adults with dementia is critical for improving the quality of  dementia care. However, research in this area remains limited in Indonesia. Purpose: This study aimed to explore the barriers and support for family caregivers in caring for older adults with dementia in Indonesia.Methods: A descriptive phenomenological study was conducted among 15 family caregivers who cared for older adults with dementia. Purposive sampling was used to recruit the participants. Inclusion criteria included primary family caregivers who provided care for four hours per day for at least six months, were proficient in Indonesian, assisted older adults in daily activities, and were capable of expressing their experiences. Data were collected using in-depth semi-structured interviews and analyzed using the Colaizzi method.  Results: This study found that family caregivers faced barriers during the care of older adults with dementia, which have decreased the quality of care. These barriers included inadequate knowledge and skills of family caregivers regarding dementia, stigma, lack of knowledge and awareness in the community, limited availability of healthcare services, and healthcare professionals’ lack of knowledge about dementia. On the other hand, support received by family caregivers within the family, support from other family caregivers, and education provided by NGOs about caring for someone with dementia have shown a positive impact in reducing the burden on caregivers and improving the quality of care. Therefore, appropriate support is essential for family caregivers caring for older adults with dementia.Conclusion: This study showed that barriers originating from family caregivers, community awareness, access to health services, and barriers from health workers have impacted poor quality of care, while the support of families, fellow family caregivers, and NGOs have contributed to good quality of care. Further studies are needed to explore the perspectives of family caregivers representing different cultures in Indonesia.
Jak kritizovat formy života: filosofie Rahel Jaeggi
Authors: Hrouda Vít
Published: October 2023

The article focuses on Rahel Jaeggi’s project of a critique of forms of life. Jaeggi seeks to create a new theory of social critique whose object is what Jaeggi calls a form of life: an ensemble of practices within which we always already live our lives and which represent solutions to certain problems. The critical procedure that Jaeggi defends is an immanent one, meaning that social critics, rather than bringing in external standards, should concentrate on contradictions characterizing forms of life themselves. This procedure presupposes a concept of social change, which happens in a rational way and admits progressive development. This concept in turn serves as the highest criterium for a critique of forms of life.

Gwarancje jakości prawa w przepisach Ustawy z dnia 6 marca 2018 r. – Prawo przedsiębiorców
Authors: Etel Maciej
Published: October 2023

The legal situation of entrepreneurs in Poland is determined by a huge number of normative acts. However, the legislator’s interest in entrepreneurs and economic activity should not come as a surprise. Indeed, an economically conscious state cannot afford to be indifferent to the entrepreneur and, even in a market economy, should normatively regulate the rules for undertaking, performing and terminating economic activities and shape the rights and obligations in this regard. It must also be remembered that the matter to be regulated is very broad, complex and multi- faceted, and the law must take into account the enormous diversity of relationships, roles, events and facts in which the entrepreneur functions in connection with their economic activity. On this basis, it can be assumed that the law that determines the rules for undertaking, performing and terminating economic activities is natural and necessary. Nevertheless, it should be clearly emphasized that the quality of the law shaping the situation of entrepreneurs and their economic activities should be prioritized as an overriding and fundamental value – the appropriate quality of the law (i.e., properly enacted and applied) is a sine qua non of economic development, while a lack of quality in the sphere of lawmaking and application makes it difficult or even impossible for entrepreneurs to function, and thus leads to stagnation or regression in the economy. The study is focused on the guarantees of the quality  of lawmaking and application empowered by the Act of 6 III 2018 – Entrepreneurs’ Law. Analyzing the provisions of this act makes it possible to identify the regulations focused on the quality of lawmaking and application. The study also aims to answer the question: Can the guarantees set out in this Act contribute to improving the quality of lawmaking and application of the law on the undertaking, conduct and termination of economic activity?
Prywatność vs. świat wirtualny: ochrona praw jednostki w dobie Internetu
Authors: Cłapińska Katarzyna
Published: October 2023

The article aims to indicate the most important issues facing an individual wishing to protect his or her privacy on the Internet. It also describes the evolution of the concept of the right to privacy, which over the years has become one of the most important subjective rights reﬂected both in the Polish Constitution and in the legal acts of the Council of Europe and the European Union. The text also demonstrates the approach to the issue of the right to privacy taken by both the Polish constitutional and international judiciary. The European Court of Human Rights in Strasbourg, in the cases of Dupate v. Latvia and Brother Watch and others v. United Kingdom, dealt with both the publication of photographs of a public ﬁgure taken surreptitiously in a private situation and mass surveillance. The Court of Justice of the European Union in Luxembourg, in its judgments, has often referred to the issue of the protection of telecommunications data, including the question of access by state services to such data (H.K case) and the rights and obligations created by Articles 7 and 8 of the Charter (Kärntner Landesregierung and Digital Rights Ireland Ltd case). The European Union authorities, reacting to the increasingly widespread problem of data ﬂows on the Internet, decided to enact the General Data Protection Regulation (GDPR). The article describes the most important objectives and tasks to be fulﬁlled by this legal act. In addition, the main problems associated with the use of new technologies such as cybercrimes, cyber surveillance, data theft, as well as cryptojacking and the functioning of APTs (Advanced Persistent Threat), i.e. skilled hacking groups, are also indicated.

Evaluation and low carbon ecological urban–rural planning and construction based on energy planning mechanism
Authors: Xiu Yujiao
Published: October 2023

In response to the problems of lack of planning in management and high difficulty in law enforcement in urban and rural planning (URP for short here) and construction, this article proposes to apply the concept of low-carbon ecology (LCE) to URP and construction and reasonably optimize URP and construction. This article provided a relevant analysis of urban and rural energy planning issues and applied the concept of LCE to URP and construction. This article constructed a framework for evaluating urban and rural carbon emissions, which is used to evaluate carbon emissions issues in URP and construction. This article also combines artificial neural network algorithms to further conduct experimental analysis on the scale of URP and construction land. In contrast, during the same period, the construction land scale of our algorithm increased by 179,800 acres less than that of the machine learning algorithm. The per capita area of urban and rural construction land decreased by 16.5 m2, and the gross domestic product (GDP) output of urban and rural construction land increased by 1.95 billion yuan. The algorithm in this article has increased by 155,200 acres compared to the construction land scale under deep learning. The per capita area of urban and rural construction land decreased by 7.1 m2, and the GDP output of urban and rural construction land increased by 915 million yuan. In summary, this algorithm can effectively increase the GDP output of urban and rural construction land, slow down the expansion of construction land scale, and play a good auxiliary role in URP and construction.
Monolingual disobedience, multilingual guilt?: an autoethnographic exploration of heritage language maintenance during COVID-19 lockdowns
Authors: Zhang-Wu Qianqian
Published: October 2023

In this study I indicate that lengthened family interaction time during pandemic lockdowns can afford children significantly more exposure and opportunities to enhance their heritage language, but that this does not diminish the constant dilemma between striving to balance English acquisition and heritage language maintenance. Using autoethnography, and as a first-generation immigrant mother of a preschool-age Chinese American child, I will demonstrate how our family language policy and languaging practices evolved during the COVID19 lockdowns, and indicate how, despite the growing development of my child’s heritage language skills, her multilingualism was achieved at the cost of my constant ideological struggles between disobeying rampant English-only ideologies in society and feeling guilty about decentering academic English in our family language policy. With this study, I call for future research to adopt a longitudinal lens to explore whether shifting family language policies and languaging practices during lockdowns may have long-term influences on children from multilingual households.
Oil Prices Pass-Through to Domestic Inflation: Symmetric Versus Asymmetric Pass-Through
Authors: Mahmoud Ali Israa Ali , Ghoneim Hebatallah , Smolny Werner
Published: October 2023

This paper analyses the world oil price pass-through to Egypt’s domestic inflation rate. The paper adopts the augmented Phillips curve framework and further extends it to consider the growing body of empirical evidence, suggesting that oil prices may have asymmetric effects on inflation. Accordingly, the paper examines and compares the symmetric and the asymmetric oil price pass-through to domestic inflation in the short run and the long run. A linear ARDL-ECM and the bounds cointegration tests are applied as well as a nonlinear asymmetric NARDL model and Wald tests for short-run and long-run asymmetries. The sample consists of quarterly data covering the period from 2001 Q3 to 2019 Q2. The results show that, in the short run, the pass-through of world oil prices to the Egyptian domestic inflation rate is symmetric and of small magnitude. However, on the long-run, oil price pass-through to inflation appears to be nonlinear and asymmetric, specifically, declining oil prices lead to a fall in domestic inflation that is more significant than the rise in inflation caused by rising oil prices.
‘Trying to open the doors’: The co-creation of digital resources for disadvantaged primary school pupils
Authors: Thiele Tamara , Homer Damien
Published: October 2023

This article explores the use of co-creation as an approach for involving university students in the development of educational initiatives for widening participation (WP) in higher education (HE) during the COVID-19 pandemic. At present, research and guidance looking at how co-creation practices can enable the production of such initiatives within HE is highly limited, which can deter others from employing this approach. To this end, we provide a case study of a WP project called Topic in a Box that involved staff and students working together to produce digital learning material for primary schools and students over several months. Through the use of semi-structured interviews with nine students, this research provides insight into the steps that were taken to develop the project, capturing the motivations, benefits and challenges of co-creation practice from a student perspective. We argue that this mode of co-creation should be used to a greater extent across the university sector and in recognition that university students have much to offer in terms of widening access to university.
Passing the (proverbial) baton: Engaging students as partners in module design
Authors: Allen Emma
Published: October 2023

Student-staff partnership, understood as the situation when students and staff work together on a project, contributing equally but in potentially different ways, is an innovation that is gaining traction on university campuses worldwide. This case study details my first foray into the partnership arena. I invited undergraduate students from the Schools of Law and Geography, Geology, and the Environment at Keele University to partner with me in designing a new optional module–Contemporary Issues in Environmental Law. My aim here is to provide an honest warts-and-all account of the experience, written from my perspective. I will document the positive outcomes for both the students and staff participating, of which there were many, but also some of the challenges faced. Despite these challenges, there can be no doubt that student-staff partnership is a worthwhile endeavour, and I hope others can view this as an example that can be adapted to suit their specific contexts.
Different Faces of Medial Beta-Band Activity Reflect Distinct Visuomotor Feedback Signals
Authors: Schwey Antoine , Battaglia Demian , Bahuguna Jyotika , Malfait Nicole
Published: October 2023

Beta-band (13–35 Hz) modulations following reward, task outcome feedback, and error have been described in cognitive and/or motor adaptation tasks. Observations from different studies are, however, difficult to conciliate. Among the studies that used cognitive response selection tasks, several reported an increase in beta-band activity following reward, whereas others observed increased beta power after negative feedback. Moreover, in motor adaptation tasks, an attenuation of the postmovement beta rebound follows a movement execution error induced by visual or mechanical perturbations. Given that kinematic error typically leads to negative task–outcome feedback (e.g., target missed), one may wonder how contradictory modulations, beta power decrease with movement error versus beta power increase with negative feedback, may coexist. We designed a motor adaptation task in which female and male participants experience varied feedbacks—binary success/failure feedback, kinematic error, and sensory-prediction error—and demonstrate that beta-band modulations in opposite directions coexist at different spatial locations, time windows, and frequency ranges. First, high beta power in the medial frontal cortex showed opposite modulations well separated in time when compared in success and failure trials; that is, power was higher in success trials just after the binary success feedback, whereas it was lower in the postmovement period compared with failure trials. Second, although medial frontal high-beta activity was sensitive to task outcome, low-beta power in the medial parietal cortex was strongly attenuated following movement execution error but was not affected by either the outcome of the task or sensory-prediction error. These findings suggest that medial beta activity in different spatio-temporal-spectral configurations play a multifaceted role in encoding qualitatively distinct feedback signals.

SIGNIFICANCE STATEMENTBeta-band activity reflects neural processes well beyond sensorimotor functions, including cognition and motivation. By disentangling alternative spatio-temporal-spectral patterns of possible beta-oscillatory activity, we reconcile a seemingly discrepant literature. First, high-beta power in the medial frontal cortex showed opposite modulations separated in time in success and failure trials; power was higher in success trials just after success feedback and lower in the postmovement period compared with failure trials. Second, although medial frontal high-beta activity was sensitive to task outcome, low-beta power in the medial parietal cortex was strongly attenuated following movement execution error but was not affected by the task outcome or the sensory-prediction error. We propose that medial beta activity reflects distinct feedback signals depending on its anatomic location, time window, and frequency range.
Nutritional and metabolic control of germ cell fate through O‐GlcNAc regulation

Published: October 2023

Fate determination of primordial germ cells (PGCs) is regulated in a multi‐layered manner, involving signaling pathways, epigenetic mechanisms, and transcriptional control. Chemical modification of macromolecules, including epigenetics, is expected to be closely related with metabolic mechanisms but the detailed molecular machinery linking these two layers remains poorly understood. Here, we show that the hexosamine biosynthetic pathway controls PGC fate determination via O‐linked β‐N‐acetylglucosamine (O‐GlcNAc) modification. Consistent with this model, reduction of carbohydrate metabolism via a maternal ketogenic diet that decreases O‐GlcNAcylation levels causes repression of PGC formation in vivo. Moreover, maternal ketogenic diet intake until mid‐gestation affects the number of ovarian germ cells in newborn pups. Taken together, we show that nutritional and metabolic mechanisms play a previously unappreciated role in PGC fate determination.
Paradigmenwechsel ante portas? Die neue Letztsicherungsfazilität (Backstop) des ESM

Eine der wichtigsten Neuerungen der im Januar 2021 beschlossenen Reform des Europäischen Stabilitätsmechanismus (ESM) ist die Letztsicherungsfazilität, auch Backstop genannt. Sie wird, wenn der ESM-Änderungsvertrag in Kraft getreten ist, das Bindeglied zwischen der Bankenunion und dem für Staaten konzipierten „Rettungsschirm“ bilden. Im Anschluss an eine Positionsbestimmung des Backstop im System der unionalen Sicherungsmechanismen geht dieser Beitrag der Funktionsweise (und der Funktionalität) der Letztentscheidungsfazilität und dabei nicht zuletzt der Frage nach, ob sie im Einklang mit der auch rechtlich verbindlichen Maxime steht, Bail-out zu verhindern.
Lieferkettensorgfalt aus Bankensicht

Published: October 2023

Das seit dem 1. 1. 2023 geltende Lieferkettensorgfaltspflichtengesetz (LkSG) hat als Regelungsadressaten maßgeblich Unternehmen der Realindustrie vor Augen. Die Einbindung der Finanzindustrie in die Human Rights Due Diligence wird allerdings seit Langem diskutiert. Der EU-Gesetzgeber schickt sich nunmehr an, dies mit der geplanten Corporate Sustainability Due Diligence Directive umzusetzen. Der nachfolgende Beitrag zeigt den bestehenden und im Werden begriffenen Rechtsrahmen für Banken und Kreditinstitute auf. Dabei beleuchtet er zugleich den Hintergrund des die Entwicklung maßgeblich treibenden Soft Law. In seinen Schlussfolgerungen werden die bislang kaum diskutierten Prämissen einer verstärkten Einbindung der Finanzindustrie in lieferkettenbezogene Sorgfaltspflichten hinterfragt und die Notwendigkeit alternativer Konzepte verdeutlicht.

Der Beitrag untersucht den Entwicklungsstand von Angeboten algorithmischer Kapitalanalagedienstleistungen und ordnet diesen in den Rahmen des Aufsichts- und Haftungsrechts ein. Dabei ist festzustellen, dass „intelligente“ Robo Advice-Angebote nicht im Markt anzutreffen sind; weitgehend bleibt es bei einer algorithmischen Unterstützungsfunktion auf Basis überkommener finanzmathematischer Modelle. Während der aufsichtsrechtliche Rahmen bereits gut erschlossen ist, müssen die anzutreffenden Intransparenzen und drohenden Interessenkonflikte besonders sensibel behandelt werden. Zudem sind die spezifisch algorithmenbezogenen Sorgfaltspflichten für die Anbieterhaftung noch nicht abschließend geklärt. Hier wird eine Fernwirkung der künftigen KI-VO entwickelt, womit sowohl dem Gebot bestmöglicher Interessenwahrnehmung zu Gunsten der Kunden genüge getan als auch Rechtssicherheit hergestellt würde.

Erklärte Ziele: Den Markt für renditeorientiertes Crowdfunding in Europa zur Beseitigung der Fragmentierung des Rechtsrahmens auf ein neues Fundament zu stellen, den Wettbewerb zwischen Crowdfundingplattformen zu verbessern und Marktteilnehmern in kleinen Mitgliedsstaaten mit weniger ausgeprägten Crowdfundingmärkten besseren Zugang zu Kapital und Anlagemöglichkeiten zu geben. Mit Ablauf des Übergangszeitraums am 10. 11. 2023 gilt die ECSP-VO für alle in ihren Anwendungsbereich fallenden Crowdfunding-Modelle verpflichtend.

Noch vor Verabschiedung des finalen Entwurfs der Verordnung wurde in der Literatur vor allem die Frage nach dem Anwendungsbereich aufgeworfen, die auch heute noch nicht eindeutig beantwortet ist. Genau dieser Frage widmet sich ausweislich des Untertitels Johannes Öhmann in seiner Dissertation zur ECSP-VO mit Blick auf die deutschen Anlageformen. Das Entstehen der Problematik drängt sich auf: Da die Regulierung europäisch ist, sich in den Ländern jedoch bisher verschiedene Modelle des Crowdfundings herausgebildet haben, muss untersucht werden, wie sich die nationalen Crowdfunding-Modelle und die jeweils genutzten Anlageformen zur ECSP-VO verhalten. Während sich Öhmann auf die größte Frage des produktspezifischen Anwendungsbereichs konzentriert (welche Rechtsgestaltungen sind als Anlageinstrumente von der ECSP-VO erfasst?), sollen hier auch noch einige weitere jüngst behandelte Fragen zum Anwendungsbereich thematisiert werden.

The purpose of this study was to describe the distinct cognitive trajectories for 8 years according to living arrangement among community-dwelling older adults using the Korean longitudinal study of ageing.We analyzed data from a final sample of 3,049 community-dwelling older adults aged 65 years or older who participated in at least three cognitive function measures in an 8-year period (2012-2020). Cognitive function was assessed by Korean mini mental state examination. Latent class growth model analysis was applied to determine the number and shape of trajectories of older adults according to living arrangement. Multinomial logistic regression analysis was used to determine risk factors for cognitive function trajectories.We identified five trajectory patterns in cognitive function among older adults living alone; ‘high-stable (35.6%)’, ‘high-declining (32.5%)’, ‘moderate-steep declining (6.2%)’, ‘low-stable (18.9%)’, and ‘low declining (6.8%)’. In older adults living with family, there were four trajectory patterns; ‘high-stable (46.4%)’, ‘high-declining (32.0%)’, ‘low-stable (15.9%)’, and ‘low-declining (5.7%)’. Age, instrumental activities of daily living, and depression were common factors of cognitive changes in both older adults living alone and those living with family members. However, monthly incomes was only associated with the risk of cognitive function in older adults living alone.We found that cognitive function trajectories among older adults may differ depending on the type of living arrangement. Therefore, further studies and health policies are required for avoiding cognitive impairment by living arrangement among older adults based on the results of this study.

New archeological research was conducted in the Suburbs of Chernihiv in 2022. It was 150 m to the west from the defensive line of the Okolny Grad and this made it possible to study this part of the city and trace its development in different chronological horizons. At the end of the 10th — at the beginning of the 11th centuries this place was used as a barrow and soil burial ground. At the end of the 11th century there emerged manor buildings directly near the fortifications, which could have been destroyed in 1094. At this time three residential buildings were registered. The boundaries of estates in the shape of ditches from fences appeared at this stage and had the same borders for all time periods. In the first half of the 12th century new buildings were erected, which could also have been destroyed in the fire in 1152. A clay oven was discovered in one of the houses, where the plinth was used as a structural element during its construction. Fragments of the plinth were also found in other buildings. The parameters of such a plinth are similar to the plinth of the Illinska Church on the Boldyni Hory near the entrance to the caves. A similar plinth is found in the masonry of the Saints Borys and Hlib Cathedral. In the second half of the 12th — the first half of the 13th centuries increased the number of houses and household building. At one of them a processed elk horns were found, that can indicate a bone-cutting workshop. During all chronological periods manor buildings were fixed, but houses, household buildings and fences were always oriented by walls on the sides of the world. Constructions of the first half of the 13th century could have disappeared as a result of a fire during military operations in 1234—1235 or after the Mongol invasion. After the cessation of life in this part of the city, a cemetery appeared on the territory of the former estates, the burials of which were arranged in the pits of houses of the first half of the 13th century. The cemetery could function even after the Mongol invasion. The density of buildings and the presence of burials from different time periods attest to the intensive use of this part of the Suburbs of Chernihiv during Old Rus period.
