Enhanced Engagement Nurtured by Determination, Efficacy, and Exchange Dimensions (EENDEED): A Nine-Item Instrument for Measuring Traditional Workplace and Remote Employee Engagement
Authors: Lartey Franklin M. , Randall Phillip M.
Published: January 2022

With the ongoing pandemic and technological evolutions, remote work has become the new normal. However, existing employee engagement instruments do not take the remote aspect of work into account. This paper proposes a nine-item instrument for assessing employee engagement in general, and remote worker engagement specifically. The instrument was named EENDEED, for enhanced engagement nurtured by determination, efficacy, and exchange dimensions. It was grounded on three theories: (1) self-determination; (2) self-efficacy; and (3) social exchange. After generating the proposed scale grounded on the literature and theory, data were collected from 626 participants in the United States through an online survey. The dataset was split in two random samples of 405 and 195 cases respectively, after eliminating 26 cases with missing values. An exploratory factor analysis (EFA) on the larger sample helped discover its two-factor structure, namely PERFORMANCE and SELF-RELIANCE. A confirmatory factor analysis (CFA) was performed on the second sample, which confirmed the two-factor structure of EENDEED. A final study assessed the reliability and validity of EENDEED. Data were collected through an online survey of 162 employees in the U.S. A CFA was conducted, validating the two-factor structure of the instrument. Construct reliability of the factors and reliability of the scale were ascertained. Face validity, content validity, construct validity, and criterion validity were confirmed. This study fills the gap in current engagement measurements by including the remote worker dimension. Organizations will be better able to identify and address challenges faced by traditional workplace employees and remote workers.

Sick and Blamed: Criminal Law in the Chilean Response to COVID-19

The Chilean government called upon ideas of social solidarity to fight the pandemic of SARS-CoV-2 and it relied heavily on the criminal law in order to secure compliance with sanitary restrictions. However, because restrictions and prosecutorial policy did not take into account social background and people’s ability to comply with the law, prosecutions soon created groups of people who were being both over-exposed to disease and death, and over-exposed to control, blame and punishment. The configuration of this overpoliced and underprotected group became so visibly unjust that appealing to social solidarity to justify the criminal enforcement of sanitary restrictions became almost insulting. This forced the Fiscal Nacional to develop a ‘socially sensitive’ prosecutorial strategy, something that we have not often seen despite Chile’s inequalities. The changes in policy by the Fiscal Nacional suggest that perhaps, at times, penal institutions can be made accountable for acting in ways that create estrangement rather than cohesion.
Suffering from Vulnerability

Suffering from Vulnerability. On the Relation Between Law, Contingency and Solidarity

The COVID-19 crisis has produced or amplified disruptive processes in societies. This article wants to argue for the fact that we understand the meaning of the COVID-19 crisis only if we relate it to the fundamental vulnerability of modern life and the awareness of vulnerability of whole societies. Vulnerability in modernity are expressions of a reality of freedom that is to some extent considered contingent and therefore unsecured. It is true that law is understood today as the protective power of freedom. The thesis of the article, however, boils down to the fact that the COVID-19 crisis has resulted in a new way of thinking about the protection of freedom. This also means that the principle of solidarity must be assigned a new social role. Individual and societal vulnerability refer thereafter to an interconnectedness, dependency, and a future perspective of freedom margins that, in addition to the moral one, can also indicate a need for legal protection. In this respect, law has not only a function of delimitation, but also one of inclusion.
The Exceptionality of Solidarity

The Exceptionality of Solidarity

In times of crisis, we witness exceptional expressions of solidarity. Why does solidarity spring in times of crisis when it wanes in normal times? An inquiry into what may explain the differences between the expression of solidarity in crisis vs. normalcy provides, as I will argue in this article, important insights into the conditions and nature of solidarity. Solidarity requires, I will contend, an egalitarian ethos and state action within and beyond the state. It is neither a momentary political ideal, nor an exclusionary one, which depends for its sustainment on formal, legal, structures. Transient, sectarian, and informal conceptions of solidarity unduly curtail the demands of solidarity by restricting its reach to times of crisis, to in-group recipients, and to the social rather than the legal sphere. The article concludes by discussing some aspects of the dynamics of solidarity and its inherent risks that the analysis of the exceptionality of solidarity helps bring into focus.
Populism, the Kingdom of Shadows, and the Challenge to Liberal Democracy

Populism, the Kingdom of Shadows, and the Challenge to Liberal Democracy

Populism is a somehow intractable notion, since its reference is much too wide, comprising phenomena that are indeed in conflict between them, and moreover blurred, by being often used in an instrumental, polemical way. Such intractability is then radicalized through the two alternative approaches to populism, one that is more or less neutral, rooting in the political science tradition, and a second one, fully normative, though fed by political realism, founding as it does on a specific political theory and project. In the article an alternative view is proposed, that of populism as the politics that is congruent with the increasing role played by ‘screens’, icons, and images in social relationships and indeed in political representation. In this way populism is approached as the specific way politics is done within the context of a digitalized société du spectacle.

Legal Philosophy as an Enrichment of Doctrinal Research – Part II: The Purposes of Including Legal Philosophy

Many doctrinal legal research questions require making use of other academic disciplines or perspectives. This article explains the relevance of legal philosophy for doctrinal research projects. Often legal research questions have conceptual or evaluative dimensions that presuppose philosophical understanding. For research on the concept of democracy, the function of constitutional rights, or the possible introduction of a referendum in the Netherlands, questions of a philosophical nature need to be answered. Legal philosophy can supplement and enrich doctrinal research in various ways. In this article, we present seven purposes that legal philosophy may serve in the context of a doctrinal research project: conceptual clarification, exposition and reconstruction of fundamental normative principles and values, theory building, providing creative perspectives, structural critiques, evaluation, and recommendations. For each objective, we illustrate how to use relevant philosophical methods. Thus, this article complements our earlier publication ‘Legal Philosophy as an Enrichment of Doctrinal Research – Part I: Introducing Three Philosophical Methods’. http://www.lawandmethod.nl/tijdschrift/lawandmethod/2020/01/lawandmethod-D-19-00006.

Published: January 2022

This paper presents methods for the disarticulation and steam kettle maceration of embalmed and non-embalmed decedents for forensic casework and curation in anatomical collections. As steam kettles are becoming more commonly used, details on infrastructure and necessary tools for steam kettle maceration are included. This technique was developed over the course of four years of steam kettle use for forensic anthropological casework and full body anatomical donation macerations for Western Michigan University Homer Stryker M.D. School of Medicine’s (WMed) Body Donation Program. Steam kettle maceration efficiently processes decedents and results in high quality skeletal specimens with little to no damage. Furthermore, this method has the advantage of requiring minimal disarticulation, no chemical agents, and minimal intervention or attention by the processor.

Neste trabalho foram consideradas características da camada física LoRa com um histórico de observações da SNR por janela deslizante para a troca automática de conﬁguração. Os resultados obtidos em um cenário real mostram que a técnica de janela deslizante apresentou, na melhor conﬁguração, uma redução média relativa de 16, 26% no número de trocas com um aumento médio relativo de 36, 73% no ganho de SNR para esta mesma conﬁguração, quando comparado com a técnica sem janela.
Research on Natural Phenolic Compounds in FAB-Lab: Nonconventional Industrial, Pharmaceutical, and Therapeutic Applications
Authors: A. Badria Farid
Published: January 2022

Phenolic compounds represent one of the secondary metabolites of plants with pharmaceutical and therapeutic applications. Flavonoids, quinones, bioflavonoids, neo-lignans, xanthones, curcuminoids, tannins, and coumarins are some examples of the major groups of commonly available phenolic compounds in our daily foods, beverages, and spices. From this standpoint, the Liver Research Laboratory (FAB Lab) at Mansoura university, Egypt, established a multidisciplinary research (chemistry, molecular biology, bioinformatics, pharmacology, and pharmaceutics) based on utilization of commonly abundant natural products from plants and agricultural wastes, especially phenolic compounds to meet the goal of applied scientific research in pharmaceutical industry, environment, public health, and to furnish a sustainable well-developed globe. Examples of our concerted efforts, for over 30 years, are in the area of natural products and utilization of environmental waste containing phenolic compounds for various health disorders (cancer, cataract, degenerative diseases, hyperpigmentation, hyperglycemia, skin disorders), nano-, green and click chemistry. This chapter presents a practical model from FAB-Lab to maximize the benefits from phenolic natural products that have not been optimally exploited to establish meaningful scientific applied research. Patents, innovations, and significant publications indexed by the Web of Science and Scopus databases in the journals that occupy the 1st and the 2nd quartile will be presented.

Published: January 2022

The article concisely illustrates the vegetation dynamics and interrelationships among Man, Animal and Plant species of the insular tropical rain forests found to occur in Andaman-Nicobar Islands in the Bay of Bengal. There are two aboriginal groups known as ‘Onges’ and ‘Shompens’ living in different islands such as the Little Andaman Island and the Great Nicobar Island are mostly depends on the forest vegetation for their livelihood. The delicacy of these two ancient aboriginal groups towards wild honey in their food habits is quite time immemorial. Interestingly, it is found that the insular vegetation dynamics has a key role to gratify their needs in this regard. The two endemic plant species of the insular vegetation viz. Orophea katschallica Kurz and Etlingera fenzlii (Kurz) Škorničk. & M. Sabu is traditionally used by these primitive aboriginal communities for honey collection from the large wild hives of the ferocious rockbee (Apis dorsata Fabricius). The article also included details on chemical characterisation of Etlingera fenzlii.

Metrics of Resident Achievement for Defining Program Aims
Authors: Jewell Corlin , Kraut Aaron , Miller Danielle , Ray Kaitlin , Werley Elizabeth , Schnapp Bejamin
Published: January 2022

Introduction: Resident achievement data is a powerful but underutilized means of program evaluation, allowing programs to empirically measure whether they are meeting their program aims, facilitate refinement of curricula and improve resident recruitment efforts. The goal was to provide an overview of available metrics of resident achievement and how these metrics can be used to inform program aims.

Methods: A literature search was performed using PubMed and Google Scholar between May and November of 2020. Publications were eligible for inclusion if they discussed or assessed “excellence” or “success” during residency training. A narrative review structure was chosen due to the intention to provide an examination of the literature on available resident achievement metrics.

Results: 57 publications met inclusion criteria and were included in the review. Metrics of excellence were grouped into larger categories, including success defined by program factors, academics, national competencies, employer factors, and possible new metrics.

Conclusions: Programs can best evaluate whether they are meeting their program aims by creating a list of important resident-level metrics based on their stated goals and values using one or more of the published definitions as a foundation. Each program must define which metrics align best with their individual program aims and mission.
The Effect of Valproate Sodium on the Electrical Activity of Helix aspersa F1 Neurons in a Pentylenetetrazole-Induced Epileptic Model Using an Intracellular Recording System
Authors: Ganjkhane Mahin , Marahem Marzieh , Parizad Mohammad Amin , Beheshtirouy Samad
Published: January 2022

Background: Epilepsy is a chronic central nervous system disorder with a high prevalence in modern society. Despite using common anticonvulsant drugs, its control is not adequately achieved. Animal models for seizures play the leading role in advancing our understanding of the cellular mechanisms of epilepsy. The present study was an attempt to elucidate the electrophysiological mechanism of the effect of sodium valproate on the cellular model of epilepsy. Understanding the cellular mechanisms of this drug may help clarify the pharmacological screening of other drugs. Methods: The intracellular recording was made from F1 cells of garden Helix aspersa in the presence of Ringer solution. Following the extracellular application of valproate sodium at a concentration of 10 mM after and before the use of (25mM) epileptogenic agent (pentylenetetrazol (PTZ)), we evaluated its effect on paroxysmal depolarization shift (PDS) and electrophysiological characteristics. Results: These results showed that valproate sodium could reduce neuronal excitability. It could significantly hyperpolarize rest action potential by decreasing the frequency of firing rate and increasing the amplitude of afterhyperpolarization (AHP) and can prevent depolarization of rest action potential by PTZ. Conclusions: The results suggested that valproate sodium could reduce the PTZ-induced hyperexcitation by hyperpolarization of resting membrane potential (RMP), a reduction in AHP amplitude, and firing the frequency.
Justiças, Punição e Vinganças na Filosofia de Arthur Schopenhauer
Authors: Durante Felipe
Published: January 2022

Este texto tem por objetivo, a partir da leitura e análise dos escritos publicados e de manuscritos póstumos do filósofo Arthur Schopenhauer – em especial os textos relativos a sua ética –, explorar os contrastes e articulações entre dois tipos de justiça aventados pelo autor em sua obra, a saber, a Justiça Temporal (zeitliche Gerechtigkeit) e a Justiça Eterna (ewige Gerechtigkeit), a partir dos conceitos de lei (Gesetz), punição (Strafe) e de vingança (Rache), oriundos da justiça temporal, e do conceito de vingança enquanto braço da Justiça Eterna (Arm der ewigen Gerechtigkeit). Tal objetivo tem como pano de fundo a tentativa de relacionar e articular os âmbito da moralidade e da legalidade, isto é, a metafísica e a ética do filósofo.
Subjetividade no Segundo Wittgenstein
Authors: Almeida João Henrique Lima
Published: January 2022

Este escrito contém a crítica de noções tradicionais de subjetividade realizada pelo assim chamado Segundo Wittgenstein, cujo pensamento se expressa principalmente nas Investigações Filosóficas. Como o próprio Wittgenstein recomenda, as passagens de seu segundo pensamento serão confrontadas às suas primeiras formulações sobre o “sujeito”, que tinham relação íntima com a noção de sujeito em Schopenhauer. Após abordarmos brevemente a concepção de sujeito no Tractatus, apresentaremos três aspectos da crítica wittgensteiniana da subjetividade a partir de suas Investigações. Após isso, comentaremos duas tentativas de se extrair uma formulação positiva da subjetividade em Wittgenstein, realizadas por Chantal Bax e Søren Overgaard. Além de expor o aspecto negativo, ou crítico, das formulações de Wittgenstein sobre a subjetividade, pretendemos responder se o sujeito e a subjetividade, para o Segundo Wittgenstein, podem ser conhecidos, e se é possível extrair uma formulação positiva da subjetividade dos escritos wittgensteinianos.
Der Staat und die Begriffe des Rechts und Unrechts in Schopenhauers „politischer Metaphysik“
Authors: Gebrecht Raphael
Published: January 2022

Die vorliegende Abhandlung versucht die systematischen und ontologischen Gründe für Schopenhauers politische Philosophie darzulegen, indem insbesondere auf die Verbindung von kontraktualistischen und metaphysischen Elementen in seiner Staatskonzeption eingegangen wird. Dabei wird sich zeigen, dass Schopenhauers Begriffe des „Rechts“ und „Unrechts“ innerhalb eines institutionellen Gesamtrahmens nicht ohne den systematischen Horizont der „Welt als Wille und Vorstellung“ begriffen werden können, der insbesondere auf der kantischen Unterscheidung zwischen Erscheinung und Ding an sich beruht. Die immanenten Implikationen seiner metaphysischen Annahmen sollten daher als Grundlage für staatliches Handeln und der damit verknüpften Funktion von Autorität, die sich in institutionalisierter Strafe und anderen Einschränkungen niederschlägt, mitbedacht werden, insofern sie letztlich als phänomenale Manifestationen eines universellen Substrats zu begreifen sind, das Schopenhauer als „Wille“ bestimmt.

Schopenhauer e a demarcação do lugar de sua filosofia segundo ele mesmo
Authors: Moraes Dax
Published: January 2022

Pretende-se com este artigo encontrar um possível esclarecimento para a afirmação de Schopenhauer segundo a qual somente a Vontade é o unicamente Real, uma tese publicada pela primeira vez em A vontade na natureza que exigiria várias mudanças em sua obra capital, uma vez que se torna a definitiva demarcação do pensamento de Schopenhauer com relação a seus antecessores. Esse problema nos levou a considerar a relação entre Schopenhauer e Kant em vista de descobrir o sentido próprio dessa tese, bem como o de alguns aspectos da crítica levantada pelo primeiro contra o segundo. Nesse sentido, aproveita-se para destacar muitas passagens novas ausentes na edição de 1819 de O mundo como vontade e representação, além de uma cuidadosa consideração de suas anotações ao exemplar pessoal.
Wille und Erkenntnis: Synthese, Dualismus oder Aporie? Ein konzeptionelles Grundproblem der Philosophie Schopenhauers
Authors: Novembre Alessandro
Published: January 2022

The relationship between will and cognition represents one of the most fundamental issues in Schopenhauer’s philosophy. The possibility of aesthetic experience, which involves a deliverance of cognition from the service of the will, and even more so the doctrine of the redemption through cognition – the fact that cognition can become a “tranquillizer” of the will and bring will to abolish itself – seems incompatible with Schopenhauer’s voluntaristic metaphysics (i.e., with the principle of the “primacy of the will”). This paper aims to analyse this controversial part of Schopenhauer’s discourse, especially in its implications for the system’s logical consistency, and tries to provide a theoretical and genetic explanation of the question.
Worldwide complexity of weeds
Authors: Pacanoski Zvonko , Mehmeti Arben
Published: January 2022

No more than 3% of the total plant species on the Earth account for weeds, but they cause significant problems to humankind by intruding in food security and safety, health, environment, economic stability, and welfare. The problem of weeds as a worldwide problem increases, as human activities and their interference with the environment are increasing. Weeds owing to their forceful and flexible nature, cause considerable losses in agriculture, forestry, aquaculture, water supply and a variety of other human enterprises. Overall, weed-crop competition is the most important cause reducing sustainable crop production. They decrease production due to competition, allelopathy, and by providing environment for pathogens, serving as alternate hosts for numerous insects and fungi, thus causing an increase in harvesting expenditures. Weeds are prominent yield reducers, often economically more significant than insects, pathogens or other biotic constrains altogether. Worldwide damages generated by weeds are responsible for a loss of 13.2% of crop yields, but the probable losses in agricultural production without weed control are predicted at 20-90% globally.

Published: January 2022

The effectiveness of 12 pre-em herbicides in controlling ragweed was studied: atrazine, alachlor, acetochlor, alachlor+linuron, S-metolachlor, pendimethalin, metribuzin, prometryn, napropamide, imazethapyr, oxyfluorfen and dichlobenil. The research was conducted over two years, where the herbicides were applied in May on soil that had been prepared for sowing, but not sown. The efficacy was observed 30, 45 and 60 days after the application. Herbicides were used in 4 different doses: D1 which is ½ of the recommended dose, D2 is the lowest recommended dose, D3 is the highest recommended dose and D4 is the dose where the herbicides were used with the dose higher than it is recommended (D3×1,5). Efficacy is expressed as the percentage of efficacy for the number and fresh weed biomass, compared to the control. Coefficient of multiple correlation between the percentage of efficacy (PE), as a dependent variable, and the dose (D) and the number of days from the application of herbicides (DAA), as independent variables is statistically significant and in all cases it ranges between 0,853** and 0,961****. Partial correlation coefficient of efficacy percentage dependent on the herbicide dose is positive and in almost all cases highly significant, varying from 0,739** to 0,956****. Partial correlation coefficient between the herbicide efficacy percentage for common ragweed biomass and time after herbicide application is negative and statistically significant, or highly significant and varies between -0,606* and -0,904***. The partial correlation coefficient of the herbicide efficiency percentage for the common ragweed plant number and days after herbicide application, is also negative and varies, depending on the herbicide, between -0,182NZ and -0,923****.

Published: January 2022

The aim of the research was a histological study of the tissue structure of experimental animals with burns in dynamics using various topical agents after the injury. Experimental simulation of burn injuries was performed on 40 rats, which were divided into the main and control groups. Depending on the nature of care provided, the animals of the main group were divided into subgroups: in the 1st subgroup a uniform layer of sunflower oil was applied, in the 2nd subgroup dexpanthenol was sprayed, in the 3rd subgroup prompt neutralization of traumatic action was performed with a gauze napkin soaked in water. Animals from the control group were not treated. The examination involved a histological study. The results confirmed the negative impact of applying oil to the burnt area as a means of first aid, which caused more pronounced degenerative changes of the dermis and its structures with the involvement of hypodermis in the pathological process, prolonging the duration of healing. As for the use of dexpanthenol spray for burn injuries, the histological changes of tissues did not differ much from those in animals of the control group, which did not receive any care. At the same time, histological findings of the tissues of animals treated with moistened wipes was characterized by less pronounced pathological changes. Histological analysis of tissue changes of the burnt area in dynamics objectively proved the effectiveness of water as the main pathogenetic element of emergency care in an experiment.
Systemic sclerosis and pulmonary arterial hypertension: A case report
Authors: Aleksić Ivana , Šarić Sandra , Ilić Bojan , Stojanović Sonja , Deljanin-Ilić Marina
Published: January 2022

Pulmonary arterial hypertension (PAH), which occurs in about 15% of patients with systemic sclerosis (SSc), is a progressive vasculopathy and despite modern therapeutic options is still one of the leading causes of death in these patients. We presented a patient diagnosed with the overlap syndrome (systemic sclerosis and rheumatoid arthritis) with a predominance of the clinical picture of systemic sclerosis (SSc), established in November 2018. She was initially treated by a rheumatologist with an antimalarial, which was soon discontinued by an ophthalmologist, followed by azathioprine which was excluded due to an allergic reaction. She has been continuously on corticosteroid therapy, and since January 2020, mycophenolate mofetil has been added to treatment. The patient was diagnosed with primary biliary cirrhosis by a gastroenterologist after clinical findings and additional examination methods; also, pulmonary fibrosis was diagnosed by a pulmonologist. In January 2020, deterioration of echocardiographic findings was registered (dilated right heart cavity, right ventricular systolic pressure (RVSP) 72 mmHg, tricuspid regurgitation 3+). Sildenafil was proposed by a responsible cardiologist for therapy that was not approved by gastroenterologist. Due to worsening of her symptoms in the form of pronounced fatigue, shortness of breath, in August 2020, a cardiologist of the Institute "Niška Banja" started bosentan therapy in a dose of 2 x 62.5 mg per day. After the applied therapy, the patient had a subjective improvement and reduction of symptoms. In November 2020, a control echocardiographic examination registered a decrease in RVSP to 55 mmHg. In addition to the therapy proposed by the responsible rheumatologist (mycophenolate mofetil 2 g daily, prednisolone 15 - 20 mg daily), the therapy prescribed by her cardiologist was also continued (bosentan 62.5 mg 2 x 1), with regular controls and monitoring of laboratory analyses. PAH in patients with SSc has a worse prognosis than idiopathic PAH, and additionally depends on RVSP and functional class. The process of treating PAH in patients with SSc requires a complex strategy that includes initial assessment of disease severity and subsequent responses to the therapy.

Published: January 2022

Energy consumption reduction per unit of product' removed moisture is necessary to lower production costs and increase the overall efficiency of the dehydration process. The goal of this research was to analyse efficiency and economics of the peach in molasses osmotic dehydration process, by investigating mass transfer parameters. Time, concentration and temperature of the osmotic dehydration of peach in molasses were varied and responses of water loss and solid gain were measured. The results showed that with the technological parameters of time, concentration and temperature increase, individual mass transfer parameters also increased, where maximal values of 0.7524 g/gi.s. and 0.1069 g/gi.s., were obtained for water loss and solid gain, respectively. On the basis of experimental data, mathematical models of peach osmotic dehydration in molasses responses dependence from applied technological parameters were developed, which showed good correlations between experimental and calculated results. Combined technological efficiency parameter analysis showed a total efficiency increase in the range of 40.67 to 51.71%, by using process temperature of 20°C. The highest process economics was obtained by application of energy undemanding process temperature of 20°C, where energy costs were avoided while at the same time achieved highest value of technology efficiency.
Exploring guest satisfaction in hotels during the COVID-19 pandemic using a text mining technique
Authors: Čelić Irena , Seočanac Marijana , Milašinović Marko
Published: January 2022

The coronavirus pandemic has a major impact on the global hotel industry. Hygiene, cleanliness, and safety have become crucial components in any hotel's recovery plan during the pandemic. Based on reviews from Booking.com, this paper examines the satisfaction of domestic guests in hotels in Vrnjačka Banja during the coronavirus pandemic. Additionally, by using the "Clean & Safe" certificate as a criterion for hotel classification, this paper seeks to discover whether there is any difference in the satisfaction of domestic guests depending on whether the facility has been certified in accordance with international quality standards as adequately prepared for virus control. Using a text mining approach, the components that led to guests' satisfaction or dissatisfaction were discovered and visualized with a word cloud. A sample of 206 reviews revealed that domestic guests are generally very satisfied with the hotels they stayed in during the pandemic. A slight difference in the components that affected guests' satisfaction, i.e., dissatisfaction, was noticed among the hotels that were certified (or not certified) as safe facilities for performing tourism activities. This paper provides a valuable insight for hotel managers to help them improve guest satisfaction during the coronavirus pandemic.

Estas responsabilidades deben de ser también analizadas a la luz de lo establecido en el código deontológico de la profesión aprobado por la Asamblea General de la Organización Internacional de Ceremonial y Protocolo en 2006.

La relevancia pública de la actividad del responsable de protocolo exige, a quien desempeña esta profesión, el conocimiento y aplicación de la normativa relacionada con los símbolos oficiales. Al prestar sus servicios en una administración pública su actuación no afecta solo a ésta, sino también a todos aquellos que se relacionan con ella, por lo que el adecuado uso y mantenimiento de los símbolos que representan a todos los ciudadanos debería ser una de las actitudes habituales y significativas que menciona el código deontológico de la profesión.

La metodología observacional permite analizar el estilo motivacional que despliega el docente en clase y proporciona una nueva perspectiva para interpretar la influencia de las interacciones docentes en el proceso de instrucción. El objetivo de este trabajo fue diseñar una escala de estimación ad hoc para la Medida del Estilo Interpersonal Docente (MEID) y validarla Participaron 30 docentes universitarios (16 mujeres y 14 hombres) con una edad media de 46.1 años (DT = 5.8) y con una experiencia docente de 15.71 años (DT = 6.9). La calidad del dato fue alcanzada a través de la técnica de validez de contenido y el aspecto cuantitativo fue tratado por medio del análisis del W de Kendall, ajustando un modelo final de 60 ítems agrupados en 4 dimensiones exhaustivas y mutuamente excluyentes: apoyo a la autonomía, apoyo a la estructura antes de la tarea, apoyo a la estructura durante la tarea y apoyo a la relación. Las evidencias iniciales de la escala MEID lo presentan como un instrumento psicométrico robusto y fiable para poder ser empleado como técnica observacional del estilo interpersonal docente. Los resultados obtenidos abren nuevas líneas de estudio en las que la escala MEID podría ser empleada en programas formativos encaminados a la optimización de patrones motivacionales docentes adaptativos.
The first case of novel variants of the FSHR mutation causing primary amenorrhea in 2 siblings in Korea

Follicle-stimulating hormone receptor (FSHR) mutation is a rare cause of amenorrhea. We report the first case of FSHR mutations in Korea. Two female siblings, aged 16 (patient 1) and 19 (patient 2) years, were referred to the pediatric endocrinology clinic because of primary amenorrhea despite normal breast budding. Gonadotropin-releasing hormone stimulation test showed markedly elevated luteinizing hormone and follicle-stimulating hormone with a relatively low level of estrogen, suggesting hypergonadotropic hypogonadism. Pelvic magnetic resonance imaging revealed a bicornuate uterus in patient 1 and uterine hypoplasia with thinning of the endometrium in patient 2. The progesterone challenge test revealed no withdrawal of bleeding. After two months of administration of combined oral contraceptives, menarche was initiated at regular intervals. To determine the genetic cause of amenorrhea in these patients, whole exome sequencing (WES) was performed, which revealed a compound heterozygous FSHR mutation, c.1364T>G (p.Val455Gly) on exon 10, and c.374T>G (p.Leu125Arg) on exon 4; both of which were novel mutations and were confirmed by Sanger sequencing. The patients maintained regular menstruation and improved bone mineral density while taking combined oral contraceptives, calcium, and vitamin D. Therefore, FSHR mutations can be the cause of amenorrhea in Koreans, and WES facilitates diagnosing the rare cause of amenorrhea.

Peculiarities of professional training of penal institution personnel during the Great Patriotic War
Authors: Voloshin Denis Vladimirovich
Published: January 2022

The research subject is the actualization of organizational and pedagogic peculiarities of professional training of penal institutions personnel during the Great Patriotic War. Professional training of penitentiary personnel in today’s Russia, aimed at the formation of competent professionals, traditionally deals with the question of continuity of education fundamentals at particular time line.   The research is based on archive materials of the State Archive of the Russian Federation. The research methodology includes the method of historicism, and the system approach, the chronological method (historical periodisation), the methods of historical retrospective and historical comparison, which help to analyze archive sources from the viewpoint of contemporary historical and pedagogical science.  The authors study the historical and pedagogical materials and analyze the experience, as well as theoretical and practical results of the search for new approaches, means and methods of professional training and improvement of conceptual background of the educational sphere of penal service of Russia.  During the period under study (the years of the Great Patriotic War), the most effective organizational and pedagogical models were searched for, as well as their orientation towards school education with prevailing in-service training.   
Rendering public and municipal services via information and communication technologies as the element of e-democracy
Authors: Lolaeva Al'bina Slavovna
Published: January 2022

This research is dedicated to the issues of rendering public and municipal services via information and communication technologies as the element of e-democracy. The relevance of this topic is substantiated by the overall digitalization of public relations, including the provision of public services. The article covers the question of the emergence and development of the institution of public and municipal services; determines the essence of rendering public and municipal services along with the peculiarities of their legal regulation; demonstrates the transformation of the right of citizens to appeal to the government; describes the purpose of the administrative reform and the concept of its implementation; characterize the powers of the executive authorities exercised through multifunctional centers; establishes the forms of interaction between the executive authorities and multifunctional centers in the context of administrative reform; indicates the current state of the model instilled in the existing concept of rendering public services. The scientific novelty consists in the fact that within the framework of legal research of the problems and prospects of rendering public and municipal services via information and communication technologies as the element of e-democracy, substantiation is given to the authorial approaches towards definition of public (municipal) services provided in digital form. The conclusion is formulated that the prospect for the improvement of the quality of public services became the concept MFC 2.0, which suggests that 90% of the country's population would have access to the system of rendering public and municipal services in digital form. This creates a reliable platform for the activity of institutions of e-democracy, as well as participation in democratic processes and procedures in digital format.
Disinformation, misinformation and fake news in the time of the Covid-19 pandemic. A corpus-based approach
Authors: Kusz Ewa
Published: January 2022

The Covid-19 outbreak and its dissemination resulted in the creation of a new, specialised and global discourse among the population. This paper aims to investigate a tsunami of dis- and misinformation on the basis of selected, most frequently occurring, items of fake news to show how the ‘infodemic’ (Covid-19-related misinformation) has expanded, and how fake news is structured. The paper concludes by presenting patterns of fake news, including grammar structures, the frequency of the given lemmas and collocations, in the hope that it will provide greater transparency, help to flatten the ‘infodemic’ curve and make the readers more aware of how myths about coronavirus have been formed during the pandemic.
Solution of the boundary value problem of heat conduction in a cone

Published: January 2022

In the paper we consider the boundary value problem of heat conduction in a non-cylindrical domain, which is an inverted cone, i.e. in the domain degenerating into a point at the initial moment of time. In this case, the boundary conditions contain a derivative with respect to the time variable; in practice, problems of this kind arise in the presence of the condition of the concentrated heat capacity. We prove a theorem on the solvability of a boundary value problem in weighted spaces of essentially bounded functions. The issues of solvability of the singular Volterra integral equation of the second kind, to which the original problem is reduced, are studied. We use the Carleman-Vekua method of equivalent regularization to solve the obtained singular Volterra integral equation.
