The Impact of SARS-CoV-2 Pandemic Lockdown on a Botulinum Toxin Outpatient Clinic in Germany
Authors: Samadzadeh Sara , Brauns Raphaela , Rosenthal Dietmar , Hefter Harald
Published: January 2021

Botulinum neurotoxin type A (BoNT/A) injections have to be administered repeatedly to achieve a rather stable, high level of improvement. This study aimed to take a look at changes in the daily routine of a BoNT/A outpatient clinic due to the SARS-CoV-2 pandemic lockdown, analyze the impact of SARS-CoV-2-induced re-injection delay on outcomes in patients with cervical dystonia (CD) (n = 36) and four other disease entities (n = 58), and study the influence of covariables, including previous injections and doses. For the present observational study, the first 100 patients who were scheduled to have an appointment between April 20 and May 18 during the partial lockdown and also had been treated regularly before the lockdown were recruited. Clinical and demographical characteristics and treatment-related data from the previous visits were extracted from charts. Time delay, symptom severity assessment, and TSUI score (if applicable) were gathered at the first coronavirus pandemic lockdown emergency visit for each patient. Of the 94 patients who could come to the clinic, 48 reported a delay and 44 reported worsening during the delay. Delays ranged from 1 to 63 days, the mean delay was 23 days, and the mean worsening was 26% compared to the previous visit. A significant correlation was found between the duration of the delay and the patient’s rating of worsening (PwP). In CD patients, the physician´s rating of CD worsening by the TSUI score (ATUSI-PTSUI) was significantly correlated with general worsening (DwP) and the TSUI at the last visit (PTSUI). A small delay of a few weeks led to a similar worsening of symptoms in CD and all other disease entities and to relapse on a higher level of severity. This relapse can only be compensated by continuous treatment up to at least 1 year until patients reach the same level of treatment efficacy as that before the SARS-CoV-2 pandemic.
Superfluid Dynamics in Neutron Star Crusts: The Iordanskii Force and Chemical Gauge Covariance
Authors: Gavassino Lorenzo , Antonelli Marco , Haskell Brynmor
Published: January 2021

We present a geometrical derivation of the relativistic dynamics of the superfluid inner crust of a neutron star. The resulting model is analogous to the Hall-Vinen-Bekarevich-Khalatnikov hydrodynamics for a single-component superfluid at finite temperature, but particular attention should be paid to the fact that some fraction of the neutrons is locked to the motion of the protons in nuclei. This gives rise to an ambiguity in the definition of the two currents (the normal and the superfluid one) on which the model is built, a problem that manifests itself as a chemical gauge freedom of the theory. To ensure chemical gauge covariance of the hydrodynamic model, the phenomenological equation of motion for a quantized vortex should contain an extra transverse force, that is the relativistic version of the Iordanskii force discussed in the context of superfluid Helium. Hence, we extend the mutual friction model of Langlois et al. (1998) to account for the possible presence of this Iordanskii-like force. Furthermore, we propose that a better understanding of the (still not completely settled) controversy around the presence of the Iordanskii force in superfluid Helium, as well as in neutron stars, may be achieved by considering that the different incompatible results present in the literature pertain to two, opposite, dynamical regimes of the fluid system.

Published: January 2021

Currently, next generation sequencing (NGS) is the mainly used approach for identification and monitorization of viruses with a potential public health threat in clinical and environmental samples. To facilitate detection in NGS, the sequence-independent, single-primer-amplification (SISPA) is an effective tool for enriching virus sequences. We performed a preliminary assessment of SISPA-nanopore sequencing as a potential approach for screening tick-borne viruses in six specimens with detectable Crimean-Congo hemorrhagic fever virus (CCHFV) and Jingmen tick virus (JMTV) sequences. A comparison of unbiased NGS and SISPA followed by nanopore sequencing was carried out in 4 specimens with single and pooled ticks. The approach was further used for genome sequencing in culture-grown viruses. Overall, total/virus-specific read counts were significantly elevated in cell culture supernatants in comparison to single or pooled ticks. Virus genomes could be successfully characterized by SISPA with identities over 99%. Genome coverage varied according to the segment and total read count. Base calling errors were mainly observed in tick specimens and more frequent in lower viral loads. Culture-grown viruses were phylogenetically-related to previously-reported local viruses. In conclusion, the SISPA + nanopore sequencing was successful in generating data comparable to NGS and will provide an effective tool for broad-range virus detection in ticks.

Against Declarativity
Authors: Kellner Hans
Published: January 2021

Historical discourse is a period phenomenon shaped by the rhetorical and genre understanding of the moment in which it became formalized and professionalized - that is, the second half of the nineteenth century. In the figurative arts, realist painting and its rival, photography, was dominant, and the literary form this notion of consciousness took was the realist novel. Literary realism devices replaced romantic literature devices, just as those latter devices had succeeded, but never replaced the eighteenth-century devices. Historical discourse and the very notion of proper history followed realism devices, mostly the single-lens photographic perspective, one viewer’s viewpoint. From a discourse perspective, this approach took the form of declarative, statement-making. Also, it is not to say that the declarative sentence which gives this term its name was rejected as the preferred way of making assertions about the world - far from it. Although a few self-conscious stylists (Derrida, for instance) work hard to avoid it, the declarative sentence is almost inevitable. Their readers work even harder. But just as narrativity encompasses a realm that extends far beyond narratives, so that narratives can proliferate in an environment that has, in a crucial sense, rejected grand narratives, so declarative statements will exist without entailing statement-making. The declarative act became the defining mark of professional history and remained its principal mode, just as it remains the predominant mode of literature and any number of other discourses. Indeed, this essay is written in the declarative rhetorical mode. However, literary modernism, philosophy, and a host of scientific developments have left this way of representing the world behind. Moreover, the same technological and intellectual changes that caused the modernist vision have, at the same time, created a different world to be depicted, a different sort of event to be represented historically. Not only the form but also the content have changed. The ethical and practical frustrations of representing such events have led to a theoretical challenge to the declarative form of knowing and to a challenge for the genre distinctions that constitute guild history: the idea of the past produced by academically professionalized individuals. For example, the difference between history and fiction - or rather, their respective relationship to truth and reality - has blurred. In contrast, history has adopted some of the modernist literature devices and the present’s practical demands.
The Unrevealing Nexus between Foreign Direct Investments, Institutional Quality and Financial Development in Pakistan

Published: January 2021

The study examines the nexus between FDI, institutional quality, and financial development in Pakistan. We believe that it is a novel research attempt as it covers both democratic and non-democratic regimes. We use linear ARDL methodology to predict the nature of the relationship as a baseline estimator and Granger causality as a robustness check for further validation of results. The study covers the period from 1990 to 2018. We find that both FDI and institutional quality positively affect financial development in Pakistan. We find bi-directional causality between financial development and institutional quality and a unidirectional casualty between FDI and institutional quality. Likewise, we also find a unidirectional causality between FDI and financial development, running from financial development to FDI. The study has some managerial implications for policymakers to strengthen the country’ macroeconomic environment and to encourage institutional reforms to boost up the confidence of local as well as foreign investors.

The Psychological Development of Horizontal (Lateral) Violence in Health Services
Authors: Kennedy Bernice
Published: January 2021

Abstract
Workplace violence has a major impact on productivity, morale, increase absenteeism, turnover, patient outcome, and cost. The hierarchy of the hospital structure is based on a patriarchal system dominated by male physicians and administrators with nurses in the lower position. However, because of nurses being in a lower position of hierarchy, their frustrations are acted out laterally (horizontally) toward other nurses. This paper is an analysis of the literature in addressing the psychological process of lateral (horizontal) violence among health healthcare employees in health services organizations. A model was developed describing this psychological process with the proposed impact of preventive strategies. Horizontal hostility or lateral violence (LV) has been defined as unkind, discourteous, antagonistic interactions between employees in the workplace. Also, nurses experienced numerous physical and psychologic stress and even death. In many health services organizations, this horizontal/ lateral violence behavior is accepted and considered the norm and often overlooked and not reported. Health services organizations need to promote better working relationships among healthcare professionals to have better patient outcomes

The Role of DART Key Building Blocks as Customer Co-Creation Determinants in Islamic Banking Services
Authors: Asnawi Nur , Setyaningsih Nina Dwi
Published: January 2021

Co-creation is a baseline for innovation strategies to increase market share and competitive advantage in the Islamic Banking industry. The purpose of this study is to examine the role of the DART (dialogue, access, risk and transparency) model as a determinant of co-creation activities in Islamic banking. It is the first empirical investigation that tests the DART model in this way. Using Partial Least Squares Structural Equation Modeling, this study analyzes the responses of 192 Islamic bank customers to test four proposed hypotheses. The research result confirms that the dialogue and transparency of the DART model positively support co-creation activities. Our study is based on data from Islamic Banking customers in Indonesia; therefore, it needs to be retested in a broader context. Since we distributed questionnaires among Islamic Banking customers, future studies could compare their responses with those of customers of conventional banks. Further studies are recommended to develop the DART model in other specific contexts. It is important for Islamic Banking managers in Indonesia to prioritize dialogue and information disclosure in serving customers while also allowing customers access to information to and delivering risk assessments honestly.
At the Crossroads of Modernity: Critical Anthropology in Contemporary Europe
Authors: Baer Monika
Published: January 2021

This article addresses anthropological involvement in a political sphere constituted by the politicization of “difference” in European modernity projects, and in this context, especially conflicts related to gender, sexuality, race, nationality/ethnicity, or religious beliefs, which result in visions of antagonized, political Others. The author refers to the autoethnographic perspective and discusses her own disciplinary practices from the mid-nineties to today, pointing to the positive and negative sides of those practices. She first discusses the idea of critical anthropology as an element of academic activist debates within gender and queer studies. Then she looks at a more academic position, which makes critical anthropology into an instrument for creating images of a better future. Ultimately, she advocates a vision of critical anthropology that focuses on affective agency, thanks to which conflicting factions may perceive shared experiences and feelings. She does not assume that this kind of critical engagement is capable of bringing about broader social or political change, but believes it could make a contribution to acceptance of the Other on the micro-scale.

Published: January 2021

This article aims to characterise the positive and negative aspects of being a national minority, using the example of the German minority in the Opolskie Voivodeship and the category of social welfare in the sociological sense. In order to conceptualise and operationalise the idea of national identity, attention has been focused mainly on its cultural determinants, with particular emphasis on the role of language and organisational activity. The empirical exploration of the research questions was based on surveys, carried out by the authors of the article on behalf of the Social-Cultural Society of Germans in Opole Silesia (SCSG) in the summer of 2019, among members of the German minority organisation.   [1] The research was carried out in the period from June to August 2019 as part of the SCSG's campaign entitled “The German minority has a value”, financed by the Polish Ministry of Interior and Administration.
Początki politycznej kariery czołowych polityczek CDU i CSU na poziomie federalnym w Niemczech w latach 1991–2018
Authors: Piotrowska Marlena
Published: January 2021

The article focuses on the first steps in the political career of female politicians from the Christian Democratic Union (CDU) and the Christian Social Union (CSU), who assumed top political positions at the federal level in Germany between 1991 and 2018. The author analyses when the female leaders of the CDU and CSU took their first parliamentary seats in the German Bundestag, when they obtained the first leading positions at the federal level, and also how many years after joining the party this took place. It is also interesting whether top female politicians took their first parliamentary seats through votes in direct districts or thanks to the party list (second votes). Do the career paths of the female politicians from the Christian Democrats fit the model of typical career paths, or do they also include those who have avoided key positions on their way to the top?

Hybrid-based Framework for COVID-19 Prediction via Federated Machine Learning Models
Authors: Kallel Ameni , Rekik Molka , Khemakhem Mahdi
Published: January 2021

The COronaVIrus Disease 2019 (COVID-19) pandemic is unfortunately highly transmissible across the people. Therefore, a smart monitoring system that detects and tracks the suspected COVID-19 infected persons may improve the clinicians decision-making and consequently limit the pandemic spread. This paper entails a new framework integrating the Machine Learning (ML), cloud, fog, and Internet of Things (IoT) technologies to propose a COVID-19 disease monitoring and prognosis system. The proposal leverages the IoT devices that collect streaming data from both medical (e.g., X-ray machine, Lung UltraSound machine, etc.) and non-medical (e.g., bracelet, smartwatch, etc.) devices. Moreover, the proposed hybrid fog-cloud framework provides two kinds of federated ML as a Service (federated-MLaaS); (i) the distributed batch-MLaaS, which is implemented on the cloud environment for a long-term decision-making, and (ii) the distributed stream-MLaaS installed into a hybrid fog/cloud environment for a short-term decision-making. Stream-MLaaS use a shared federated prediction model stored into the cloud; whereas the real-time symptom data processing and COVID-19 prediction are done into the fog. The federated ML models are determined after evaluating a set of both batch and stream-ML algorithms from the Python’s libraries.
Don Lorenzo Milani and his school. The problems and perspectives of education in the “Lettera a una professoressa”
Authors: Crescenza Giorgio
Published: January 2021

The article deals with a historical-pedagogical analysis concerning the previous and following years the publication of Lettera a una professoressa, by observing the context and some phenomena with essential elements. Specifically, detailed references are reminded in order to clarify the thought and the work of the prior of Barbiana. The social, economic and political contradictions of the post-war period that reflect in the Italian school education emerge: the class-oriented structure of society, the marks used for selective and justicialist purposes, early school dispersal. Only from the 70s, after the teaching of Latin was removed from secondary school, 1968 and free access to University, education becomes a common good, by bringing about the principles of the Constitution. The close analysis of Don Milani still catches the motivation to give due considerations for education in general, for integration processes and of “I Care” of which the current social context is greatly necessary with its various “emergences”: the importance of language, the dedication to foster self-esteem processes, the choice for the tutoring technique and of cooperative-learning. Based on a visionary ideal of cooperative and tolerant society, the Don Milani method proposes a new humanism by turning into a leading school model. The article includes significant conclusions from the Lettera for educational topicality, for the issues it calls and for the solutions it requires, first of all the pedagogical-social demand of a school for all and everyone which avoids “to make equal parts among unequal”.
Advancing the UN Sustainable Development Goals through Education Abroad
Authors:   The Forum on Education Abroad
Published: January 2021

These guidelines serve to direct the education abroad sector toward social, economic, and environmental sustainability by connecting the Standards of Good Practice for Education Abroad and the United Nations Sustainable Development Goals (henceforth referred to as the SDGs). The focus of the SDGs is to advance sustainable development, and have received widespread recognition around the globe as a critical pathway to assure the long-term maintenance and enhancement of human well-being in light of finite planetary resources (see definitions). The SDGs are the center of the 2030 Agenda for Sustainable Development, which provides a shared blueprint for peace and prosperity for people and the planet. These guidelines, like the SDGs, recognize that sustainability—via sustainable development framed by the SDGs—is an important aspect of promoting social and economic well-being around the world and counteracting climate change. Furthermore, aligning practices with the United Nations SDGs is crucial to The Forum on Education Abroad’s mission to “cultivate educators who champion high quality education abroad experiences that ignite curiosity, impact lives, and contribute to a better world.” This is because the SDGs are global and aspirational, representing a monumental change in practices, values, and priorities resulting from ground-level action across all nations and sectors. By aligning with the SDGs, education abroad can be carried out in a way that not only benefits people but also enriches the planet.
Extracorporeal circulation time without clinical outcome of patients with cardiac surgery
Authors: Colling K. , Zanettini A. , Stochero G. , Casarin R. G. , Sachetti A.
Published: January 2021

Introduction: Cardiovascular diseases are the main cause of death in Brazil and are related to the need for cardiac surgery using cardiopulmonary bypass (CPB), which can cause complications. Objectives: Analyze the influence of CPB time on the clinical outcomes of patients undergoing cardiac surgery at a hospital in Rio Grande do Sul, Brazil. Method: Retrospective study, by consulting the records of cardiovascular surgeries performed at the institution's operating room from 2013 to 2017. The sample was divided into two groups, the cutoff point used was the median CPB time (89 minutes). Statistical analysis was performed using version 26.0 of the SPSS (Statistical Package for the Social Sciences). The variables were described as mean, standard deviation, frequency and absolute number, comparisons between categorical variables were made using the Chi-square test and between numerical variables using Student's t test. An alpha less than or equal to 5% was considered as statistical significance. Results: The sample consisted of 236 patients, 66.1% male, mean age 60.52 ± 12.63 years, and patients with older age had a longer CPB time. The most frequent cardiac surgery was myocardial revascularization, followed by valve replacement and double correction surgery, most of the procedures occurred electively. Most of the procedures followed some complication in the immediate postoperative period, with the group with the longest CPB time showing greater statistical significance for complications and mortality. There was no significant difference when considering the length of stay and the cause of death. Conclusion: The procedures had a median CPB time of 89 minutes. Older patients, hemodynamically unstable at the beginning of surgery, and who underwent double surgical correction remain in cardiopulmonary bypass longer. CPB time greater than 89 minutes is related to a greater number of complications in the postoperative period and a higher mortality rate

Penelitian ini bertujuan untuk mengetahui bagaimana meningkatkan kemampuan berbicara anak melalui media big book untuk anak usia 5 – 6 tahun. Penelitian ini merupakan penelitian tindakan kelas (PTK) yang menggunakan model Kemmis dan Mc Taggart. Subjek penelitian ini adalah 25 anak, yang terdiri dari 11 anak laki-laki dan 14 anak perempuan. Teknik pengumpulan data yang digunakan dalam penelitian ini adalah observasi kemampuan berbicara anak melalui media big book, aktivitas guru dan anak serta dokumentasi. Teknik analisis data yang digunakan pada penelitian ini adalah deskriptif kualitatif. Berdasarkan hasil penelitian diketahui bahwa terdapat peningkatan dalam kemampuan berbicara anak melalui media big book. Hal ini diketahui dari rata-rata anak yang mendapat skor 3 pada setiap indikator yaitu indikator berkomunikasi secara lisan (menceritakan kembali) siklus I sebesar 0% dan siklus II sebesar 90% artinya terdapat peningkatan sebesar 90%. Pada indikator menyusun kalimat sederhana secara terstruktur (SPOK) siklus I sebesar 0% dan siklus II sebesar 85% artinya terdapat peningkatan sebesar 85% dan pada indikator melanjutkan sebagian cerita siklus I 0% dan siklus II sebesar 95% artinya terdapat peningkatan sebesar 95%. Pencapaian di siklus II sudah melebihi indikator keberhasilan yang telah ditentukan yaitu sebesar 75%. Berdasarkan hasil penelitian dapat disimpulkan bahwa media big book dapat meningkatkan kemampuan bericara anak usia 5 – 6 tahun. Peningkatan terjadi, dikarenakan dalam bercerita dengan menggunakan big book yang sebelumnya belum pernah diterapkan di sekolah tersebut, big book karakteristik khusus yang penuh warna-warni, gambar yang menarik, maupun kata yang dapat diulang-ulang, mempunyai plot yang mudah ditebak.

Tujuan penelitian ini adalah untuk melihat pengaruh video pembelajaran cerita dan lagu terhadap kemampuan berbicara anak usia 4-5 tahun di PAUD Harmoni. Metode penelitian yang digunakan adalah penelitian kuantitatif dengan desain penelitian true experimental (eksperimen yang betul-betul) dengan teknik Postest Only Control Design. Sampel penelitian yaitu anak usia 4-5 tahun dengan jumlah 30 orang yang dibagi menjadi 2 kelas terdiri dari 15 anak sebagai kelompok eksperimen (video) dan 15 anak sebagai kelompok kontrol (buku cerita). Indikator kemampuan berbicara yang digunakan adalah kemampuan mengulang kembali kalimat sederhana, menjawab pertanyaan sesuai pertanyaan, dan menceritakan kembali cerita atau dongeng yang pernah didengar. Teknik pengumpulan data menggunakan tes lisan yang digunakan untuk melakukan penilaian posttest antara kelas kontrol (buku cerita) dan kelas eksperimen (video) dan dokumentasi.Hasil analisis data posttest pada nilai rata-rata (mean) kelas eksperimen (video) lebih besar dibandingkan kelas kontrol (buku cerita), yaitu sebesar 30.2667 untuk kelas eksperimen (video) dan 22.0667 untuk kelas kontrol (buku cerita). Jika dilihat dari standar deviasinya kelas eksperimen (video) lebih besar dibandingkan kelas kontrol (buku cerita) yaitu 3.12745 untuk kelas eksperimen (video) dan 2.34419 untuk kelas kontrol (buku cerita). Hal ini juga ditunjukkan dengan hasil uji  Independent  Sample  T-test  pada bagian equal variances assumed  diketahui nilai Sig. (2-tailed) sebesar 0.000, menunjukkan bahwa 0.000 < 0.05 maka H0  ditolak, artinya ada perbedaan yang signifikan antara nilai belajar kelas control (buku cerita)  dan kelas eksperimen (video). Kesimpulannya adalah terdapat pengaruh penggunaan video pembelajaran cerita dan lagu yang dilihat dari perbedaan nilai rata-rata kelas yang diberi video pembelajaran cerita dan lagu (treatment) dengan kelas yang tidak diberi perlakuan (control).

Performing Structural Design and Modeling of Transformers Using ANSYS-Maxwell
Authors: ÖZÜPAK Yıldırım
Published: January 2021

Transformers have attracted great interest since they have been used due to their robustness and application in power systems. Therefore, the nominal values of transformers grow even more in larger power systems due to the constantly increasing power demand. Many types of research are carried out to increase the performance characteristics of transformers and their compatibility with power systems. There are different methods and analysis tools for these studies. One of them is ANSYS@Maxwell, which performs analysis based on the Finite Element Method (FEM). With this program, the design, modeling, analysis, and performance evaluation of the transformer in a high-performance simulation environment can be achieved through effective strategic modeling. In this study, the design and modeling of a three-phase core-type transformer with coils and terminals are explained in detail in ANSYS @ Maxwell simulation platform. Besides, the transformer models examined were adapted using ANSYS@MAXWELL software based on the finite element method. Analyzes are performed to estimate the core-losses, leak-losses, DC-losses, and winding-eddy current losses-of transformers with this program. A large number of meshes were used in FEM analysis of 2D and 3D models to examine the losses in detail.

Este artigo constitui-se de uma narrativa de aula e tem-se por objetivo abordar o tema violência presente no contexto de estudantes de uma escola municipal da cidade de Campinas. Para isso, a turma do 9.º ano realizou uma coleta de dados, pautada em entrevistas com as outras turmas da escola que estudavam no período da tarde. Após a coleta, fizeram, individualmente, a tabulação de dados de cada sala, por meio de registros pessoais e construção de gráficos a respeito de cada questão. Concluídos os gráficos individuais, coletivamente foram gerados os números totais de cada questão, com quadro e gráfico. Os alunos se mostraram surpresos com os índices estampados, como se não se sentissem pertencentes àquela realidade, porém, quando da análise das informações coletadas e representadas em forma de gráfico, realizaram a leitura, tecendo inferências a respeito, trazendo fatos da realidade vivenciada por eles, que embasavam os resultados. O trabalho completo foi exposto no evento “Mostra Cultural”. Após o evento, os cartazes ficaram fixados nas paredes da sala de aula do 9.º ano e foram utilizados pelos profissionais das outras áreas para leitura, interpretação de informações explícitas e implícitas, uma leitura para além dos dados. Este trabalho possibilitou aos alunos ler os dados apresentados no Atlas da Violência (2019) e visualizar o tema em nível estadual; e, após a aplicação de questionários, puderam constatar o quanto a violência está presente em suas vidas e nas de seus colegas e como ela interfere em suas decisões.
A equação civilizatória e a pertinência de uma educação insubordinada
Authors: Civiero Paula Andrea Grawieski , Bazzo Walter Antonio
Published: January 2021

Na narrativa deste artigo, buscamos uma estratégia, em uma perspectiva crítica, que desvele as complexidades da sociedade 4.0 imbricadas com as ações matemáticas, isto é, uma epistemologia que evidencie a concepção crítica do professor, voltada para uma educação que valorize a condição do ser humano neste planeta Terra. Apresentamos, como insubordinação criativa, na formação de professores, a inserção de variáveis da nova equação civilizatória. Fundamenta-se nos estudos sobre a formação de professores e nas preocupações da Educação Matemática Crítica, subsidiados pela pesquisa qualitativa realizada com formadores de professores de matemática de 10 instituições do Brasil, que se aproximam da educação matemática crítica. Ressalta-se a premência de grupos colaborativos e formação para os formadores de professores. Por fim, apresentamos algumas táticas para a inserção de uma insubordinação crítica na formação de professores.
