Background

Electroencephalography (EEG) microstates translate resting-state temporal dynamics of neuronal networks throughout the brain and could constitute possible markers of psychiatric disorders. We tested the hypothesis of an increased imbalance between a predominant self-referential mode (microstate C) and a decreased attentional mode (microstate D) in psychosis, mood, and autism spectrum disorders.

Methods

We retrospectively included 135 subjects from an early psychosis outpatient unit, with available eyes-closed resting-state 19 electrodes EEG. Individual-level then group-level modified K-means clustering in controls provided four microstate maps that were then backfitted to all groups. Differences between microstate parameters (occurrence, coverage, and mean duration) were computed between controls and each group, and between disease groups.

Results

Microstate class D parameters were systematically decreased in disease groups compared with controls, with an effect size increasing along the psychosis spectrum, but also in autism. There was no difference in class C. C/D ratios of mean duration were increased only in SCZ compared with controls.

Conclusions

The decrease in microstate class D may be a marker of stage of psychosis, but it is not specific to it and may rather reflect a shared dimension along the schizophrenia-autism spectrum. C/D microstate imbalance may be more specific to schizophrenia.

Objective: Inpatient glycemic control is considered an important component of hospital care and patient safety. Nevertheless, its importance in the hospital setting is often underestimated. We aimed to evaluate glycemic control in non-critically hospitalized patients in the state of Ceará, in Northeast Brazil. Methods: A cross-sectional study was conducted in three tertiary hospitals in the state of Ceará. We evaluated non-critically ill inpatients, aged 18 years or older, who had hyperglycemia during hospitalization (random plasma glucose > 140 mg/dL or self-reported diabetes mellitus [DM]). Results: We evaluated 136 patients (66.2% male, mean age 57.9 ± 16.6 years), 64% of whom had a prior DM diagnosis. Specific nutritional support for DM or hyperglycemia was prescribed for 59.6% of patients. In total, 69.9% of the patients were using insulin. Among them, 47.4% used sliding-scale regular insulin, 18.9% basal-bolus (neutral protamine Hagedorn [NPH] insulin), 28.4% basal-plus (NPH) and 3.1% basal insulin (NPH). The prescriptions given were considered adequate for 26.4% of patients. Of the patients, 69.9% presented blood glucose levels > 180 mg/dL and 29.4% presented levels > 300 mg/dL. Hypoglycemia was observed in 25.7% of patients; protocols for hypoglycemia management were prescribed for 76.5% of them. Education on diabetes during hospitalization was reported by 30.1%. Conclusion: The glycemic control regime followed neither national nor international guidelines. These data suggest a need for teams of diabetes specialists in public hospitals in Ceará, working to improve care and following protocols to guide the safety of hospitalized patients.

Ο Συστηματικός ερυθηματώδης λύκος (ΣΕΛ) είναι μια ετερογενής αυτοάνοση και δυνητικά σοβαρή νόσος. Στον ΣΕΛ, η αλληλεπίδραση μεταξύ περιβαλλοντικών και γενετικών παραγόντων οδηγεί στη διαταραχή πολύπλοκων βιολογικών δικτύων καταλήγοντας στην απορρύθμιση του ανοσοποιητικού συστήματος και σε διαφορετικούς κλινικούς φαινοτύπους. Τα Β κύτταρα είναι οι κύριοι ενορχηστρωτές των αυτοάνοσων αποκρίσεων στους ασθενείς με ΣΕΛ. Ωστόσο, οι ευρέως χρησιμοπούμενες θεραπείες που στοχεύουν τα Β-κύτταρα δείχνουν μέτρια αποτελεσματικότητα, ενώ αμβλύνουν τις χυμικές ανοσολογικές αποκρίσεις στα εμβόλια και προκαλούν ανοσοκαταστολή, αναδεικνύοντας την ανάγκη για ανάπτυξη πιο αποτελεσματικών θεραπειών που στοχεύουν τους παθογόνους κλώνους. Σε φυσιολογικές καταστάσεις, τα Β κύτταρα χρησιμοποιούν μηχανισμούς απόκρισης προς τις βλάβες του DNA (DNA damage response, DDR) για τη δημιουργία αντισωμάτων καθώς αυτά απαιτούν γενετικό ανασυνδιασμό. Αν και οι ασθενείς με ΣΕΛ εμφανίζουν αυξημένες βλάβες στα γονίδια που απαιτούνται για την αποτελεσματικότητα του DDR, ο ρόλος του DDR στην παθογένεια των Β κυττάρων παραμένει ασαφής. Επιπλέον, η ανάλυση ιστών που προσβάλλονται από τον ΣΕΛ, όπως το δέρμα, έδειξε υψηλότερα επίπεδα DDR σε σύγκριση με υγιές δέρμα. Προς αυτήν την κατεύθυνση, η μεταγραφική ανάλυση σε ολικά κύτταρα περιφερικού αίματος ασθενών με ΣΕΛ σε σύγκριση με υγιή άτομα, αναδεικνύει τους DDR μοριακoύς μηχανισμούς. Μέσω μελετών μικροσκοπίας, το προφίλ αυτό συσχετίστηκε με ενισχυμένο DDR σε Β κύτταρα τόσο ασθενών με ΣΕΛ όσο και μοντέλου ποντικού με ΣΕΛ. Χρησιμοποιώντας μεταγραφικές, πρωτεομικές και μελέτες ανοσοφθορισμού, η παρούσα διατριβή αποκαλύπτει την ενεργοποίηση του μοριακού DDR μονοπατιού ATR/Chk1 σε Β κύτταρα ασθενών με ΣΕΛ με ενεργό νόσο. Χορήγηση ιντερφερόνης τύπου Ι (IFN I) στα Β κύτταρα, βασικός μεσολαβητής της ανοσίας στον ΣΕΛ, προκάλεσε έκφραση του ATR μέσω άμεσης σύνδεσης του ρυθμιστικού παράγοντα 1 ιντερφερόνης (IRF1) στον υποκινητή του γονιδίου του. Η φαρμακολογική στόχευση του ATR, χρησιμοποιώντας έναν ειδικό αναστολέα (VE822, εμπορικά γνωστό ως berzosertib), μείωσε το ανοσογονικό προφίλ των Β κυττάρων, συμπεριλαμβανομένης της έκκρισης προφλεγμονώδων κυτοκινών, του σχηματισμού πλασμαβλαστών και της παραγωγής αντισωμάτων. Συνολικά αυτά τα ευρήματα υποδηλώνουν ότι η μοριακή σχέση IRF1-ATR είναι σημαντική για τη δραστηριότητα των Β κυττάρων στο ΣΕΛ. Συμπερασματικά, η παρούσα διατριβή αναδεικνύει τον παθογενετικό ρόλο του DDR με τη μεσολάβηση του ATR στις αποκρίσεις των Β κυττάρων που διαμεσολαβούνται από IFN Ι στον ΣΕΛ, και προτείνει τον ATR ως πιθανό νέο θεραπευτικό στόχο.

Published: May 2023

The aim of the present study was to investigate Greek kindergarten children’s reading motivation and their gender differences in reading motivation during kindergarten attendance. The sample of the present study consisted of 100 kindergarten children enrolled in public schools in Crete. The “Me and my reading profile” (MMRP) reading motivation tool was used. The MMRP was adjusted to Greek and was given to sample children in the beginning and at the end of the school year. Data analysis conducted with exploratory and confirmatory factor analysis revealed a 5-scale factorial structure in children’s reading motivation. Results showed that kindergarteners enhanced their reading motivation throughout the school year in the 3 out of the 5 extracted factors, while significant differences were found in the degree of reading motivation improvement between boys and girls. The results are important because they present data related to children’s reading motivation development at the first stages of literacy acquisition and are useful for making specific suggestions about educational practice and policy in Greece.

Introduction: Nowadays, botulinum toxin has found use in many disease entities such as chronic migraine, spasticity, bruxism and many others. Among serotypes A-E, type A is mainly used in treatment. For the therapeutic effect to be maintained, injections need to be repeated most often after 12 weeks. More frequent injections of the toxin may result in the production of neutralizing antibodies.
Aim of the study: The aim was to collect and analyze publications of application of botulinum toxin type A (BT-A) in the treatment of chronic migraine, spasticity and bruxism.
Methods and materials: We reviewed the literature available in the PubMed database using the key words: “botulinum toxin”; “migraine”; “spasticity”; “bruxism”.
Results: The use of botulinum toxin type A in patients with chronic migraine reduces the frequency of pain episodes and alleviates the symptoms. BT-A therapy reduces increased muscle tension, resulting in improved function of the upper or lower limb, facilitating the rehabilitation process, reducing pain associated with spasticity and protecting against the development of muscle contractures and secondary joint deformities. BT-A treatment of patients with bruxism reduces the level of pain and the maximum generated bite force, resulting in an improved quality of life for patients.
Conclusion: Intramuscular administration of botulinum toxin is a  safe, effective and minimally invasive method of treating  chronic migraine, spasticity and bruxism. The botulinum toxin type A is the most studied serotype used for therapeutic purposes. Future research on botulinum toxin will certainly allow wider use.
Celiac disease in children - diagnosis in light of the current 2020 ESPGHAN guidelines
Authors: Sochal Piotr , Iwaszko-Sochal Klaudyna , Szczepaniak-Wójtowicz Elżbieta
Published: May 2023

Celiac disease is a chronic immune disorder of the small intestine that is triggered by the consumption of gluten in genetically predisposed individuals. The disease is difficult to diagnose and treat, and its incidence is increasing. It can have different symptoms and clinical manifestations in individuals. Diagnosis is usually based on the presence of specific antibodies and histopathological examination of biopsy specimens from the small intestine. The only effective treatment is a gluten-free diet for life. Diagnosis of celiac disease in children is mainly based on the presence of specific an- tibodies in the blood, such as antibodies to tissue transglutaminase (tTG), antibodies to endomysium (EMA) or deamidated gliadin peptides (DGP). In addition, genetic testing is also used in diagnosis to detect the presence of HLA DQ2 or DQ8 genes, which are often present in people with celiac disease. The final diagnosis of celiac disease is based on a combination of the results of these tests and the presence of characteristic lesions in the small intestine, which are detected during endoscopy and small bowel biopsy.
Rola i zadania inspektora ochrony danych osobowych przy wdrażaniu e-administracji w jednostkach samorządu terytorialnego

Published: May 2023

There is no administration (and e-administration) without people, applicants, parties and participants in the proceedings conducted before it. Thus, one of the main activities of the administration is and will be the processing of personal data. Increasingly, the transition to e-government raises the question of the security of data of users and people using new services. The more so because practically everyone has heard and touched the problems related to data security in the network. Therefore, the role of the personal data protection officer (hereinafter referred to as DPO) is of particular importance when implementing processes related to e-administration. Each of the public units, including local government units (hereinafter referred to as local government units) were obliged to establish an DPO, and fulfilled this obligation. However, do the personal data administrators understand the tasks set for DPO or do they use their potential and capabilities? Unfortunately, practice and inspections, especially of the Supreme Audit Office (hereinafter referred to as NIK) show that the reality in many cases is far from ideal. This article is an attempt to identify the most common mistakes of local government units in cooperation with the IODO, and an attempt to find the reasons for this state of affairs.
Legal Aspects of Telemedicine in Poland and Challenges in Times of Pandemic
Authors: Kawczyńska Monika
Published: May 2023

The article presents the legal regulations on telemedicine applicable in Poland. Despite the adoption of legislation enabling the provision of health services at a distance via teleinformation or communication systems (ICT), telemedicine services were not widely used. In the opinion of doctors themselves, one of the basic barriers to the development of telemedicine in Poland was the lack of clarity of legal regulations. There was a need for legislative changes defining not only organisational and technical standards for providing medical advice at a distance, but also concerning the principles of civil, criminal and professional liability of doctors and guaranteeing the safety of patients and the protection of personal health data. The outbreak of the pandemic contributed significantly to the development of telemedicine services in Poland, in particular teleadvice, televisit and teleconsultation, as well as the wider use of technical devices monitoring the patient’s condition at a distance. It was driven by demands regarding the protection of patients’ health, the need to reduce the risk of the spread of COVID-19 and to maintain the capacity of the health system in relation to the growing needs of the population. Nevertheless, due to the necessity of quick response to emerging challenges, the legal solutions adopted during the prevailing epidemic were not without flaws.

CPR-induced consciousness (CPR-IC) out-of-hospital care: a scoping review protocol
Authors: Silvestri Lucymarie , Soh Rachel , Newton Alexander , Pearce James
Published: May 2023

Introduction:

Cardiopulmonary resuscitation-induced consciousness (CPR-IC) is an increasing phenomenon where patients in cardiac arrest receive sufficient brain perfusion to display signs of awareness during resuscitation. This is likely due to improvements in CPR, such as high-performance resuscitation and mechanical devices. CPR-IC has been shown to interfere with rescue efforts and may lead to psychological trauma in both patients and clinicians. It is often witnessed in the out-of-hospital environment, so is significant for practitioners working in this setting. While the phenomenon of CPR-IC has been recognised for several decades, there are many gaps in the literature and no consensus has been reached over its definition or management.

Methods:

The JBI scoping review methodology will be used to map the existing literature and identify the extent of clinical knowledge and any gaps regarding the management of CPR-IC in out-of-hospital cardiac arrest globally. A comprehensive electronic search strategy will be employed to source works that meet to the study’s inclusion criteria. Relevant data will then be extracted and presented in tabular form with narrative descriptions.

Discussion:

CPR-IC is being seen more frequently and, because of its effects on resuscitation, more knowledge is required about appropriate management. This protocol provides the framework for a scoping review which will outline the extent of knowledge and identify areas requiring more research regarding out-of-hospital care of the patient with CPR-IC.

Information optimization of laser scanning microscopes for real-time feedback-driven single particle tracking
Authors: Vickers Nicholas A. , Sharifi Fatemeh , Andersson Sean B.
Published: May 2023

Real-time feedback-driven single particle tracking (RT-FD-SPT) is a class of microscopy techniques that uses measurements of finite excitation/detection volume in a feedback control loop to actuate that volume and track with high spatio-temporal resolution a single particle moving in three dimensions. A variety of methods have been developed, each defined by a set of user-defined choices. Selection of those values is typically done through ad hoc, off-line tuning for the best perceived performance. Here we present a mathematical framework, based on optimization of the Fisher information, to select those parameters such that the best information is acquired for estimating parameters of interest, such as the location of the particle, specifics of the excitation beam such as its dimensions or peak intensity, or the background noise. For concreteness, we focus on tracking of a fluorescently-labeled particle and apply this framework to determine the optimal parameters for three existing fluorescence-based RT-FD-SPT techniques with respect to particle localization.
High-availability displacement sensing with multi-channel self mixing interferometry
Authors: Matha Robin , Barland Stéphane , Gustave François
Published: May 2023

Laser self-mixing is in principle a simple and robust general purpose interferometric method, with the additional expressivity which results from nonlinearity. However, it is rather sensitive to unwanted changes in target reflectivity, which often hinders applications with non-cooperative targets. Here we analyze experimentally a multi-channel sensor based on three independent self-mixing signals processed by a small neural network. We show that it provides high-availability motion sensing, robust not only to measurement noise but also to complete loss of signal in some channels. As a form of hybrid sensing based on nonlinear photonics and neural networks, it also opens perspectives for fully multimodal complex photonics sensing.
Different routes to large-intensity pulses in Zeeman laser model
Authors: Kingston S. Leo , Kumarasamy Suresh , Balcerzak Marek , Kapitaniak Tomasz
Published: May 2023

In this study, we report a rich variety of large-intensity pulses exhibited by a Zeeman laser model. The instabilities in the system occur via three different dynamical processes, such as quasiperiodic intermittency, Pomeau-Manneville intermittency, and the breakdown of quasiperiodic motion to chaos followed by an interior crisis. This Zeeman laser model is more capable of exploring the major possible types of instabilities when changing a specific system’s parameter in a particular range. We exemplified distinct dynamical transitions of the Zeeman laser model. The statistical measures reveal the appearance of the low probability of large-intensity pulses above the qualifier threshold value. Moreover, they seem to follow an exponential decay that shows a Poisson-like distribution. The impact of noise and time delay effects have been analyzed near the transition point of the system.
Precise chirp control with model-based reinforcement learning for broadband frequency-swept laser of LiDAR
Authors: Zhao Haohao , Yuan Guohui , Wang Zhuoran
Published: May 2023

Artificial intelligence (AI) has been widely used in various fields of physics and engineering in recent decades. In this work, we introduce model-based reinforcement learning (MBRL), which is an important branch of machine learning in the AI domain, to the broadband frequency-swept laser control for frequency modulated continuous wave (FMCW) light detection and ranging (LiDAR). With the concern of the direct interaction between the optical system and the MBRL agent, we establish the frequency measurement system model on the basis of the experimental data and the nonlinearity property of the system. In light of the difficulty of this challenging high-dimensional control task, we propose a twin critic network on the basis of the Actor-Critic structure to better learn the complex dynamic characteristics of the frequency-swept process. Furthermore, the proposed MBRL structure would stabilize the optimization process greatly. In the training process of the neural network, we apply a delaying strategy to the policy update and introduce a smoothing regularization strategy to the target policy to further enhance the network stability. With the well-trained control policy, the agent generates the excellent and regularly updated modulation signals to control the laser chirp precisely and an excellent detection resolution is obtained eventually. Our proposed work demonstrates that the integration of data-driven reinforcement learning (RL) and optical system control gives an opportunity to reduce the system complexity and accelerate the investigation and optimization of control systems.
Rigorous full-wave calculation of optical forces on microparticles immersed in vector Pearcey beams
Authors: Zhou Xiaoyan , Liu Shuxi , Zhao Daomu
Published: May 2023

We present the electromagnetic fields of vector Pearcey beams by employing the vector angular spectrum representation. The beams maintain the inherent properties of autofocusing performance and inversion effect. Based on the generalized Lorenz-Mie theory and Maxwell stress tensor approach, we derive the partial-wave expansion coefficients of arbitrary beams with different polarization and the rigorous solution to evaluate the optical forces. Furthermore, we investigate the optical forces experienced by a microsphere placed in vector Pearcey beams. We study the effects on the longitudinal optical force arising from the particle size, permittivity and permeability. This exotic curved trajectory transport of particles by vector Pearcey beams may find applications in the case where the transport path is partly blocked.
Transcending shift-invariance in the paraxial regime via end-to-end inverse design of freeform nanophotonics
Authors: Li William F. , Arya Gaurav , Roques-Carmes Charles , Lin Zin , Johnson Steven G. , Soljačić Marin
Published: May 2023

Traditional optical elements and conventional metasurfaces obey shift-invariance in the paraxial regime. For imaging systems obeying paraxial shift-invariance, a small shift in input angle causes a corresponding shift in the sensor image. Shift-invariance has deep implications for the design and functionality of optical devices, such as the necessity of free space between components (as in compound objectives made of several curved surfaces). We present a method for nanophotonic inverse design of compact imaging systems whose resolution is not constrained by paraxial shift-invariance. Our method is end-to-end, in that it integrates density-based full-Maxwell topology optimization with a fully iterative elastic-net reconstruction algorithm. By the design of nanophotonic structures that scatter light in a non-shift-invariant manner, our optimized nanophotonic imaging system overcomes the limitations of paraxial shift-invariance, achieving accurate, noise-robust image reconstruction beyond shift-invariant resolution.
Two-color attosecond chronoscope
Authors: Wu Jianan , Che Jiayin , Zhang Fabin , Chen Chao , Li Weiyan , Xin Guoguo , Chen Yanjun
Published: May 2023

We study ionization of atoms in strong orthogonal two-color (OTC) laser fields numerically and analytically. The calculated photoelectron momentum distribution shows two typical structures: a rectangular-like one and a shoulder-like one, the positions of which depend on the laser parameters. Using a strong-field model which allows us to quantitatively evaluate the Coulomb effect, we show that these two structures arise from attosecond response of electron inside an atom to light in OTC-induced photoemission. Some simple mappings between the locations of these structures and response time are derived. Through these mappings, we are able to establish a two-color attosecond chronoscope for timing electron emission, which is essential for OTC-based precise manipulation.
Continuidades y transformaciones de la comunidad Ivaviyú en el Paraguay del siglo XXI

Paraguay tiene varias etnias, entre ellas, los Avá Guaraní. En este trabajo realizamos un estudio etnográfico de la comunidad más tradicional de los Avá Guaraní, según los testimonios contemporáneos, la comunidad Ivaviyú (que significa fruta madura), situada en la ciudad Canindeyú, en el distrito Yasy Cañy (Luna escondida). El método que se utiliza es la observación participante, realizando entrevistas personales y grupales, rastreo bibliográfico, y biografías de las personas. El objetivo general es investigar las transformaciones y las continuidades de la comunidad Ivaviyú, estudiar cómo las presiones sociales, económicas y políticas han impactado y siguen impactando en la vida de la comunidad indígena Ivaviyú. Como hipótesis de partida, se plantea que las presiones estatales y económicas por parte de empresas extranjeras, especialmente las brasileñas, han supuesto un auténtico reto para la sobrevivencia como comunidad. Es más, a pesar de los problemas que tienen con el acaparamiento de tierras, la desforestación, la indiferencia de los diferentes gobiernos y la violación de sus derechos, intentan mantener su cultura y sus costumbres y, en definitiva, seguir siendo Avá Guaraníes.

Published: May 2023

There are several ways that economic units can become more efficient in energy use and reduce carbon emissions. Through re-engineering processes and the development of a systematic approach to the management of resources, environment, and individuals, economic units can achieve the same results as their competitors by reducing costs and increasing revenues, as the re-engineering of green processes aims to prevent the use of resources in an unsustainable way. Taking a comprehensive approach to achieving sustainability and integrating the Balanced Scorecard (BCS) with green process re-engineering can help improve the overall performance of economic units. This study aims to identify the theoretical concept of the balanced scorecard and re-engineering green processes. Improving the performance of the plant research sample through integration between the balanced scorecard ling technology and the process re-engineering technology. The study relied on the main hypothesis that the application of the steps of integration of the balanced scorecard technology and the re-engineering of green processes has a role in improving the performance of the factory sample of the study. The study reaches several conclusions, the most important of which is that the application of integration steps contributes to improving the overall performance of the factory sample of the research from 63% to 75% and that there is a low, uneven, and significant imbalance of performance according to the balanced scorecard perspectives, where the performance of the financial perspective 83%, and the environmental and community perspective by performance 33%.

El Geoparque Mundial UNESCO Mixteca Alta (GMUMA), localizado en la porción occidente del estado de Oaxaca, al sur de México, se destaca por una variedad de rasgos geológicos y geomorfológicos, algunos representados por cuerpos ígneos intrusivos. Entre ellos están los diques expuestos en las localidades de Santo Domingo Tonaltepec, Santo Domingo Yanhuitlán y San Pedro Añañé. Estos cuerpos tabulares cortan discordantemente las rocas del subsuelo, y suelen desarrollarse en enjambres de diques individuales con orientaciones paralelas, lineares o radiales bajo la influencia de otros eventos tectónicos o estructura geológicas.

En este trabajo se identifican y cartografían los diques del GMUMA a través del análisis de imágenes satelitales, complementado con observaciones en campo donde se cotejó su presencia y se identificaron los rasgos geológico-estructurales asociados. Así mismo, con ayuda del programa Stereo32 1.0.1, se graficaron un total de 66 rumbos de los diques y se elaboraron diagramas de rosas para visualizar la dirección preferencial de los diques y relacionarlo con el régimen tectónico de la región.

Se identificaron 3 grupos de diques con trazas longitudinales que varían desde unos pocos metros hasta 1 km y con grosores aproximados de entre 4 y 5 m, con una dirección preferencial hacia el noroeste. Los diques exhiben tres tipos de morfologías: planares, escalonados y trenzados, cuyas interpretaciones y direcciones permitieron establecer que los diques están asociados a un evento tectono-magmático de tipo extensivo que se mantuvo activo durante el Eoceno, con una dirección preferencial hacia el noroeste-sureste, similar a la orientación de las fallas Tamazulapan y Cieneguilla.
Digitale Hochschulbildung als Ausleuchten von Möglichkeitsräumen
Authors: Tsirikiotis Athanasios , Schmidt Josephina
Published: May 2023

Athanasios Tsirikiotis und Josephina Schmidt beleuchten auf einem rekonstruktiven Bildungsbegriff und den Ergebnissen des Projekts DISTELL aufbauend den Möglichkeitsraum, den digitale Lern-Lehr-Elemente eröffnen. Die rekonstruierte Bedeutung der Digitalisierung für die Hochschulbildung - als eine Orientierung an Delegation der Bewährung - wird mit den theoretischen Konzepten der Interpassivität und Mimesis diskutiert. Dabei wird die Ambivalenz der Digitalisierung an Hochschulen deutlich, die sowohl Bildungsprozesse aufschieben als auch die Transformation von Selbst- und Weltverhältnissen ermöglichen kann.
Gedenkstätten heute im Spannungsfeld von Erwartungsdruck, Opferkonkurrenzen und falschen Maßstäben
Authors: Schaarschmidt Thomas
Published: May 2023

Thomas Schaarschmidt behandelt in seinem Beitrag den aktuellen Standort von Gedenkstätten zur NS-Diktatur und zur SBZ/DDR in der deutschen Erinnerungskultur nach dem Ende der SED-Diktatur. Während der Ausbau der Gedenkstätten seit den 1990er Jahren vorangetrieben wurde, drohten sie von neuen Opferkonkurrenzen, wachsenden politischen und gesellschaftlichen Erwartungen an ihre Arbeit und eigenen Ansprüchen an eine komplexe Geschichtsvermittlung überfordert zu werden. Obwohl Gedenkstätten heute unumstrittene Institutionen der historisch-politischen Bildung sind, dienen sie nicht der Affirmation eines verordneten Geschichtsbilds, sondern bieten mit ihren Ausstellungen und pädagogischen Angeboten immer wieder neue Anstöße zur Aushandlung kontroverser Geschichtsdeutungen und Perspektiven für die Bewältigung gesellschaftlicher Herausforderungen.

Zurück in die Zukunft - Überlegungen zu einer transformativen Kulturpolitik im Zyklus von Erschaffen, Bewahren und Entschaffen
Authors: Föhl Patrick S. , Klemm Suse
Published: May 2023

»Die Erkenntnis reift, dass wir eine gerechtere und zeitgemäßere Kulturpolitik im 21. Jahrhundert brauchen, die die vorhandenen Silos nach innen wie nach außen öffnet. Hierzu gehört die Überwindung sektoraler sowie spartenspezifischer Bevorzugungen ebenso, wie eine konsequente Öffnung kultureller Einrichtungen. Der Beitrag formuliert Gedanken bezüglich einer dafür notwendigen transformativen Kulturpolitik im Zyklus von Erschaffen, Bewahren und Entschaffen«.
Gesellschaftlicher Zusammenhalt als Legitimation für eine Kulturpolitik der Zukunft?
Authors: Crückeberg Johannes
Published: May 2023

Johannes Crückeberg widmet sich in diesem Beitrag der Frage, ob der gesellschaftliche Zusammenhalt als Legitimation für Kulturpolitik dienen kann. Der Text untersucht die neoinstitutionalistische Perspektive auf kulturpolitische Legitimationsmythen und skizziert die Debatte zum gesellschaftlichen Zusammenhalt. Es wird analysiert, wie Kultur zum gesellschaftlichen Zusammenhalt beiträgt und ob dieser Zusammenhang ausreichend ist, um eine Kulturpolitik der Zukunft zu legitimieren.

Vergnügen in Besatzungszeiten
Authors: Rudeck Lena
Published: May 2023

In den westalliierten Offiziers- und Soldatenclubs nach 1945 in Deutschland trafen sich Frauen und Männer der Siegernationen. Aber auch Deutsche arbeiteten in den Clubs oder besuchten sie als Gäste. Zwischen Arbeitsalltag und Freizeitvergnügen wirft Lena Rudeck einen Blick auf die sozialen Interaktionen des Clubgeschehens. Dabei fügt sie der vorliegenden Forschung zur alliierten Besatzung nach 1945 sowohl eine akteurszentrierte als auch eine geschlechterspezifische Facette hinzu. Ihre Analyse der Begegnungen unterstreicht das Verständnis von Besatzung als einen Prozess, auf den sowohl die Sieger*innen als auch die Besiegten Einfluss nehmen.
Hermann Brochs »Die Verzauberung«
Authors: Link Daniela
Published: May 2023

Hermann Brochs unvollendetes Romanprojekt »Die Verzauberung« ist ein Text der Konflikte, der Brüche und ein fast vergessenes Zeugnis der antinationalsozialistischen Literatur. Zahlreiche Themenkomplexe wie Geschlecht, Religion und Mythos, Massenwahn und Politik, aber auch Medizin prägen und strukturieren den Romankomplex. Daniela Link setzt die innere Struktur und die literarischen Wirkmechanismen des Textes in Bezug zu Brochs Wertbegriff und legt damit erstmals eine fassungsübergreifende, kontext- und konfliktfeldbezogene Analyse des Romankomplexes vor.
Klimadebatten im Zeitalter der Aufklärung
Authors: Kleinhans Bernd
Published: May 2023

Bereits im 18. Jahrhundert fragten Philosoph*innen, Mediziner*innen und Anthropolog*innen nach dem Einfluss des Klimas auf den Menschen: Waren Differenzen in Körperbau und Hautfarbe Wirkungen des Klimas? Bestimmte die Umwelt den menschlichen Charakter? Und waren unterschiedliche Staatsformen das Resultat verschiedener Klimata? Im Zentrum stand dabei auch die Frage nach der Autonomie der Vernunft gegenüber der Natur. Bernd Kleinhans gibt einen Überblick über die Klimadebatten dieser Zeit und zeichnet die Grundpositionen des Diskurses nach. Dabei wird deutlich: Die Frage nach dem Verhältnis des Menschen zu seiner Umwelt ist eines der Grundprobleme der Moderne.
Kriegsküchen in Wien und Berlin
Authors: Sprenger-Seyffarth Jenny
Published: May 2023

In Wien und Berlin öffneten während des Ersten Weltkrieges hunderte Kriegsküchen, die in Zeiten der größten Versorgungsnot täglich von hunderttausenden Menschen besucht wurden. Jenny Sprenger-Seyffarth stellt die Entstehung dieser öffentlichen Verpflegungsangebote und ihre Entwicklung über den Krieg hinaus erstmals umfassend dar. Dabei geht sie der Frage nach, inwieweit die öffentliche Massenverpflegung eine nachhaltige Veränderung der Mahlzeiteneinnahme in der Bevölkerung herbeiführte. Blieb die Versorgung in der Großküche eine aus der Not des Krieges geborene Episode oder drängte sie die private Familienmahlzeit zurück? Beide Metropolen liefern hier verschiedene Antworten.
Determination of the cane honey point of panela under open evaporation in Colombia
Authors: Rodríguez-Cediel Vladimir Antonio , Cárdenas-Barbosa José Fernando , García-Hurtado Orlando
Published: May 2023

The granulated cane honey point of panela is given when the cane honey begins to solidify, based on the crystallographic properties of the honeys. In Colombia, the solidification point of panela is usually determined in an empirical way by panela manufacturers. In this study, we evaluated an automated method to determine the point of the panela cane honeys to produce a granulated panela in the regions of Colombia, in comparison with five possible scenarios that were previously tested, but choosing experimentally the best solution. The best method for determining the level was the saturation measurement by delta of the temperatures based on the graduation of the supersaturation of the sucrose presented as a line whose slope, and the value of Tan (q) indicate an index of the degree of supersaturation.

Una mirada a la estrategia didáctica a partir de los componentes estructurantes, en la práctica de enseñanza de una profesora de preescolar
Authors: Rodríguez-Chabur Jessica del Pilar , Arias-Delgado Liliana
Published: May 2023

Este artículo plantea el análisis de la práctica de enseñanza de una profesora de grado transición, a través de la estrategia didáctica, enmarcando el aprendizaje de la conciencia fonológica en los niños del grado transición, guiados por los componentes estructurantes de esta y mediante la reflexión en pares, bajo el método de la Lesson Study en donde Pérez y Soto (2017) la entiende como proceso de desarrollo profesional en donde un grupo de colegas se reúnen para analizarla.
Se realizó un ciclo de reflexión, teniendo en cuenta las acciones constitutivas de la práctica, (planeación, intervención y evaluación), se usó para la reflexión de la planeación, el instrumento de la escalera de retroalimentación de Daniel Wilson; permitiendo llegar a unos hallazgos y posteriormente a las transformaciones de la práctica de enseñanza.
Interpretaciones del método de Descartes en didáctica del álgebra. Estudio documental
Authors: Bello-Chávez Jhon Helver , Mancera-Ortiz Gabriel
Published: May 2023

Esta comunicación presenta un estudio documental de las interpretaciones del método cartesiano en tres libros sobre enseñanza y aprendizaje del álgebra, su influencia y uso en la comprensión del álgebra escolar.
Se encontraron argumentos para indicar que algunas interpretaciones usadas en didáctica respecto a la práctica matemática de Descartes develan una concepción del método cartesiano que privilegia aspectos de tipo sintáctico y metódico, dejando a un lado el análisis del tratamiento representacional y semántico que se encuentra en la obra. La importancia educativa que se le otorga al método de análisis está relacionada con la manipulación algebraica y la construcción de un sistema simbólico, las reflexiones sobre las necesidades interpretativas, diagramáticas y semánticas del método en la solución de problemas son exiguas.

Published: May 2023

This document presents a prototype developed at the Universidad Distrital Francisco José de Caldas of a tool called Control Glove based on angular orientation that will be in charge of controlling different specialized systems, the system starts from the information that can be found in the movements of the hands, this information varies between acceleration, velocity and angular orientation with respect to the three-dimensional Cartesian plane (X, Y, Z).
The final prototype of the control glove may be used in industrial, manufacturing, educational, medicinal, and amateur applications, which will be determined depending on the use that the glove needs.
