Public Humanities in the Reconstructed University
Authors: Leonard Sophia , Reiss Benjamin , Antonio Víctor Velázquez , Fitzgerald Makenzie Renee
Published: October 2020

Colleges and universities that can withstand the fallout of the COVID-19 crisis will need to redouble their efforts to engage students in the kinds of intellectual and social experiences that cannot be attained remotely or in isolation. Public humanities, which promotes collaboration, civic and community engagement, and inter-institutional alliances, can be one such reparative force for the reconstructed university. This essay describes the work of graduate student researchers in an interdisciplinary public humanities seminar at Emory University who partnered with a large regional theater on a project involving dramaturgy and audience engagement for a spring 2020 production of Lynn Nottage’s play Sweat (first performed in 2015). The graduate seminar and the project—both before and in the wake of the COVID-19 outbreak—offer a compelling model for critical humanistic pedagogy and research that counteracts the isolation and insularity exacerbated by the pandemic.
ENPL-1, theCaenorhabditis eleganshomolog of GRP94, promotes insulin secretion via regulation of proinsulin processing and maturation

Published: October 2020

Insulin/IGF signaling in C. elegans is crucial for proper development of the dauer larva and growth control. Mutants disturbing insulin processing, secretion and downstream signaling perturb this process and have helped identify genes that affect progression of type 2 diabetes. Insulin maturation is required for its proper secretion by pancreatic β cells. The role of the ER chaperones in insulin processing and secretion needs further study. We show that the Caenorhabditis elegans ER chaperone ENPL-1/GRP94/HSP90B1, acts in dauer development by promoting insulin secretion and signaling. Processing of a proinsulin likely involves binding between the two proteins via a specific domain. We show that in enpl-1 mutants, an unprocessed insulin exits the ER lumen and is found in dense core vesicles, but is not secreted. The high ER stress in enpl-1 mutants does not cause the secretion defect. Importantly, increased ENPL-1 levels result in increased secretion. Taken together, our work indicates that ENPL-1 operates at the level of insulin availability and is an essential modulator of insulin processing and secretion.

Objetivo: analisar a distribuição espacial da COVID-19 segundo fatores socioeconômicos e demográficos no município de Uberlândia, Minas Gerais. Método: trata-se de um estudo do ecológico, transversal, utilizando dados secundários, de uso e acesso públicos, oriundos do Ministério da Saúde do Brasil, por meio das informações disponíveis no open DataSUS com casos confirmados da COVID-19 e que possuíam, em suas respectivas fichas cadastrais, os bairros de residência. Resultados: a média de idade dos casos confirmados pela COVID-19 foi de 38,83 (±14,29) anos, as faixas etárias mais atingidas foram entre 20 a 29 anos (23,2%), 30 a 39 anos (27,7%), 40 a 49 anos (22,5%), 50 a 59 anos (13,7%) e 70 a 79 anos (5,7%). Todos os setores apresentaram casos da COVID-19, sendo o oeste o mais atingido. Entre os 20 bairros com o maior número de infecção, 11 possuem renda per capita média abaixo de um salário-mínimo, oito bairros com renda per capita média de até dois salários-mínimos e apenas um bairro com renda per capita média acima de dois salários mínimos. Conclusões: o número de casos da COVID-19 foi elevado, espalhando-se rapidamente para todos os setores, afetando, principalmente, bairros de baixa renda per capita. Nos bairros com renda per capita média da população abaixo de um salário-mínimo, concentram-se os piores cenários da COVID-19. A crise global de saúde pública ocasionada pela COVID-19 revelou as desigualdades e as injustiças que ameaçam o bem-estar, a segurança e a vida das pessoas.
The multilateral security organizations at stake. NATO, OSCE and the Covid-19 emergency: an opportunity into the crisis?
Authors: Zichi Gian Lorenzo
Published: October 2020

The Coronavirus outbreak showed how nobody was prepared to this crisis and to its economic, social and political implications which now represent the main challenge for political actors. However, if the measures taken by national states to curb the sanitary emergency seem to have partially restored their capacity to address the events, the Covid-19 has struck a significant blow to the already fragile multilateral system, as exemplified by the allegations – some of them based on coherent elements of criticism, other with less objective basis and misleading – to the World Health Organization (WHO). To better investigate the impact of this unprecedented crisis on the international institutions and its implications on security, the present article aims first to shed light on how two important organizations as the North Atlantic Treaty Organization (NATO) and the Organization for Security and Co-operation in Europe (OSCE), have reacted and are acting to this crisis: an aspect  just partially covered by the public media and that deserves to be better explored to avoid misleading interpretations. Secondly, trying to offer to the national stakeholders and public opinions a useful way to look on the Covid-19’s impact on these forums, the analysis will also reflect on the possibility that this crisis could be turn by the organizations into an opportunity to relaunch themselves and become more aware of the other elements of concern as health risks, climate change and migration which, even not strictly related with the conventional interpretation of security, are posing undeniable aspects of concern. In front of the contradiction between the emerging of complex global challenges and the deteriorating of the multilateral order, this crisis should foster organizations and states to find a new reason to cooperate in answering to the future global threats, recognizing that a better security is possible only through a comprehensive approach.

Published: October 2020

Since late 2019, SARS-CoV2 pandemic has spread worldwide. After several generations without a severe pandemic, the mixture of health and economic crisis has hit populations in all continents. The high degree of connectivity that States share, enabled by the current transportation and communication technologies, caused different regions of the world to be affected by coronavirus disease at almost the same time. Yet States responses to the SARS-CoV2 pandemic were not the same. This brief focuses on the BRICS countries individual, bilateral and collective responses to the international health crisis caused by coronavirus disease, from the early detection of COVID-19 cases in China in late December 2019 to the current surge of cases in Brazil.

Published: October 2020

The spread of the Covid-19 brought global institutions, societies, states and economies in a critical position as they encounter a new worldwide multilevel crisis. At the same time, states have had to handle this crisis acquiring an interventionist role, protecting the social and economic cohesion, providing better health care services for their citizens and investing in scientific research, as a means to restrict this new pandemic. In order to handle that situation and its consequences, the use of all the available resources became necessary as well as the improvement of the cooperation between the private and the public sector. In Greece private sector has shown an unprecedented willingness for Greece’s CSR tradition, to contribute government’s efforts.

Η υγειονομική κρίση, όπως ξέσπασε τους τελευταίους μήνες στην Ευρώπη, έφερε μια μεγάλη σειρά αλλαγών στον καθημερινό βίο εκατομμυρίων πολιτών. Είναι μια κρίση που θα αφήσει το υλικό της αποτύπωμα στην κοινωνική και οικονομική ζωή όχι µόνο της Ευρώπης, αλλά και σε παγκόσμιο επίπεδο. Οι συνέπειες θα είναι ανυπολόγιστες εάν δε βρεθεί εγκαίρως ένα αποτελεσματικό φάρμακο ή ένα εμβόλιο. Πολλές ευρωπαϊκές οικονομίες θα καταρρεύσουν, ενώ ο τουρισμός θα υποστεί πλήγμα. Λαμβάνοντας υπόψιν τη σημασία που έχει ο τουρισμός σε πολλές χώρες της Ευρώπης, συντάξαμε το παρακάτω κείμενο που έχει ως επίκεντρο το υγειονομικό διαβατήριο ή πρωτόκολλο. Είναι μια πολιτική που πολλά ευρωπαϊκά κράτη θα ακολουθήσουν. Η προάσπιση της δημόσιας υγείας υπερβαίνει το ατομικό αγαθό, ενώ η οικονομία μπαίνει σε δεύτερη μοίρα.

The role of ozonated Aloe vera oil in full-thickness skin defects: Macrophage count and epithelization length parameter
Authors: Tamba Ukio Salferius , Arifin Muhamad Thohar , Nur Muhamad , Muniroh Muflihatul , Susilanigsih Neni
Published: October 2020

Background: Aloe vera has been reported to enhance keratinocyte proliferation and migration, and thereby accelerate wound healing.  Ozone therapy is an alternative medicine with disinfecting properties and strong oxidative stress induction capacity. This study aimed to evaluate the effect of Aloe vera oil provided with different dosages of ozone in accelerating the healing rate comparing two-phases; inflammation  (day 3) and proliferation (day 7) of full-thickness defect wounds in Sprague Dawley rats as an adjuvant treatment based on macrophage count and new epithelialization length.  

Methods: We conducted a study using a post-test only control group design, where a total of 50 Sprague Dawley rats were randomized into ten groups. Two control groups were administered Aloe vera oil (P1, P6), while gentamicin ointment was used in the other control group (P2, P7). Ozonated Aloe vera oil dose was used: 600 mg/ml (P3,P8), 1200 mg/ml (P4,P9), and 1800 mg/ml (P5,P10). Groups P1, P2, P3, P4, P5 were terminated on the 3rd day, while P6, P7, P8, P9, P10 were evaluated on the 7th day. Macrophage counts were assessed using a 100x magnification microscope, through hematoxylin-eosin (HE) staining, and paraffin block with Masson trichrome staining was used to measure the new epithelialization length.

Results: There were significant differences in the macrophage count on day three between the group-administered gentamicin (P2) and 1800 mg/ml ozonated Aloe vera oil (P5) (79.96;131.96, p<0,05). The new epithelialization length significantly increased in the group provided with wound treatment up to day 7, using 1800 mg/ml ozonated Aloe vera oil (P10), compared to non-ozonated Aloe vera (P6) and the gentamicin therapy (P7) (1160.88 µm;  1367.64; 2451.40 μm, p<0,05).

Conclusions: The application of ozonated Aloe vera oil to full-thickness skin defects in Sprague Dawley rats resulted in a higher macrophage count and longer new epithelialization length than in controls.
Non-invasive somatotransgenic bioimaging in living animals
Authors: Delhove Juliette M. , Karda Rajvinder , FitzPatrick Lorna M. , Buckley Suzanne M.K. , Waddington Simon N. , McKay Tristan R.
Published: October 2020

Bioluminescence imaging enables noninvasive quantification of luciferase reporter gene expression in transgenic tissues of living rodents. Luciferase transgene expression can be regulated by endogenous gene promoters after targeted knock-in of the reporter gene, usually within the first intron of the gene. Even using CRISPR/Cas9 mediated genome editing this can be a time consuming and costly process. The generation of germline transgenic (GLT) rodents by targeted genomic integration of a gene expression cassette in embryonic stem (ES) cells is commonplace but results in the wastage of large numbers of animals during colony generation, back-crossing and maintenance. Using a synthetic/truncated promoter-driven luciferase gene to study promoter activity in a given tissue or organ of a GLT also often results in unwanted background luciferase activity during whole-body bioluminescent imaging as every cell contains the reporter. We have developed somatotransgenic bioimaging; a method to generate tissue-restricted transcription factor activated luciferase reporter (TFAR) cassettes in rodents that substantially reduces the number of animals required for experimentation. Bespoke designed TFARs are delivered to newborn pups using viral vectors targeted to specific organs by tissue-tropic pseudotypes. Retention and proliferation of TFARs is facilitated by stem/progenitor cell transduction and immune tolerance to luciferase due to the naïve neonatal immune system. We have successfully applied both lentiviral and adeno-associated virus (AAV) vectors in longitudinal rodent studies, targeting TFARs to the liver and brain during normal development and in well-established disease models. Development of somatotransgenic animals has broad applicability to non-invasively determine mechanistic insights into homeostatic and disease states and assess toxicology and efficacy testing. Somatotransgenic bioimaging technology is superior to current whole-body, light-emitting transgenic models as it reduces the numbers of animals used by generating only the required number of animals. It is also a refinement over current technologies given the ability to use conscious, unrestrained animals.

Published: October 2020

Background: The study investigated the use of social media in the marketing of agricultural products and farmers turnover in South-South Nigeria. The purpose of the study was to determine the extent to which the usage of social media in the marketing of agricultural products in Nigeria can enhance efficiency and farmers’ sales turnover.

Methods: It employed the survey research design and data were collected with the help of a structured questionnaire. Research data were analysed using t-test and least square method. Results: The results showed that the use of social media (Facebook, WhatsApp and Instagram) in the marketing of agricultural products enhances efficiency and turnover of farmers through a significant reduction in the cost of marketing agricultural products as well as increased awareness and the attendant increase in demand for agricultural produce.

Conclusions: The use of social media (WhatsApp and Instagram) in the marketing of agricultural products significantly influences cost reduction and hence efficiency in marketing as well as enhances turnover of farmers through increased demand for agricultural products. Thus, the adoption of social media in the marketing of agricultural products enhances the efficiency of agricultural marketing and sales turnover of farmers in south-south of Nigeria but only the use of WhatsApp and Instagram predict efficiency and sales turnover of farmers.
Protectresses of national spirit in the Grand Duchy of Finland and Naddnipryanshchyna [Kokkuvõte: Rahvusliku vaimu kaitsjad Soome Suurvürtsiriigis ja Dnepri Ukrainas]
Authors: Kovaliov Denis
Published: October 2020

Ukraina ja Soome võrdlev ajalugu nende ühisel Vene impeeriumi koosseisu kuulumise perioodil on väheuuritud teema. See kehtib eriti nende isikute kohta, keda ajaloolased on ka oma kodumaal vähe uurinud. Käesoleva vaatenurga eesmärk on võrrelda naisõpetajate eluteid ja loomingulist pärandit. Neil nn soome ja ukraina rahvusliku vaimu kandjail oli oluline roll nende rahvaste rahvusliku vaimu ja identiteedi kujunemisel. Autor analüüsis 19. sajandi teise poole ja 20. sajandi alguse keiserliku võimu mõju Soome Suurhertsogiriigile ja Dnepri Ukrainale kui rahvuspiirkondadele. Ta leidis, et Romanovite riigil oli vallutatud rahvaste suhtes topeltstandard: ühelt poolt valitses lojaalsus ja sallivus soomlaste suhtes, teisalt venestamine ja rõhumine ukrainlaste suhtes, keda ei nähtud venelastest eraldiseisva rahvana. Autor tuvastas Euroopa teoreetikute ja haridusvaldkonna praktikute mõju naisõpetajatele Elisabeth Alanderile, Johanna Sofia Rothmanile, Thekla Johanna Wirginia Hultinile ja Sofia Lindfors-Rusovale. Autor rõhutas nende rolli soome ja ukraina rahvusliku vaimu kujunemisel tsaaririigi kriisi ajal ja iseseisvate riikide tekkimisel revolutsiooniperioodil (1917–21). Ta tõmbas paralleele nende naiste elutegevuse ja loomingulise pärandi vahel. Vaatamata geograafilisele vahemaale ja erinevatele poliitilistele vaadetele oli neil ühine eesmärk: oma kaasmaalaste harimine ja ümberkujundamine kirjaoskajateks kodanikeks.
Psychological and pedagogical characteristic of application of methods of promotion and punishment as means of socialization of teenagers with deviant behavior
Authors: Erofeeva Mariya , Zuykova Anna , Safronov Aleksey
Published: October 2020

The article handels the problem of using the methods of encouragement and punishment as a means of socializing adolescents with deviant behavior. Faced with various difficulties, a teenager may experience difficulties in the process of assimilation and reproduction of social experience that make up the essence of socialization. Against the background of objective difficulties in the process of following social norms, this category of children is faced with a variable pedagogical impact.

The main objective of the study was to identify the existing differences in the perception of the effectiveness of the methods of promotion and punishment as means of socialization in adolescents (as objects of education) and teachers (as subjects of education).

Materials and research methods In order to identify among teachers, their preferred forms of encouragement or punishment when working with deviant adolescents, at the first stage of the study, we used an author's questionnaire for teachers, which included questions about the teaching experience most often used in working with deviant teenagers of forms of encouragement and punishment, on the effectiveness of using methods of encouragement and punishment with this category of children. In addition, within the framework of this questionnaire, teachers had the opportunity to express a subjective opinion on the advisability of including in the educational process the missing forms of encouragement and punishment. The research sample included 7 teachers, carried out by class teachers in grades 7–9 of educational institutions in Kolomna, Moscow Region.

Results of the study Our study allows us to conclude that in most cases the expectations of children associated with receiving the desired promotion are not met, which in turn can subsequently form a negative attitude of the teenager towards the teacher, as well as a decrease in motivation in the performance of a task.

In addition, we have identified significant differences between the applied teachers and preferred forms of punishment by children. So, for example, if educators consider the most effective form of punishment as public censure, then children, on the contrary, prefer loyal methods of punishment, talking about such forms as remarking and removal from fulfilling responsible assignments, arguing that public punishment degrades the dignity of the child and causes even greater aggression and a desire to do “everything against”.

An interesting fact is that the teachers are against such a form of punishment as “removal from the class”, although the students themselves are not at all against such a measure, explaining this by saying that if the child interferes with the lesson, then he must leave the class.

Canadian Studies
Authors: Kenyeres János
Published: October 2020

Canadian Studies was launched in Hungary in 1979, when the first course in Canadian literature was offered at the English Department of Eötvös Loránd University, Budapest. This article is intended to explore the history of this discipline in the past 40+ years, focusing on the growing awareness of Canada and its culture in Hungarian academic and intellectual life. As early as the mid-1980s, universities in Hungary offered various courses in Canadian Studies, which were followed by a large number of publications, conferences, and the institutionalization of the field. The article gives a survey of Canadian Studies in Hungary in the international context, showing the ways in which interaction with colleagues in Europe and beyond, and with institutions, such as the Central European Association for Canadian Studies, have promoted the work of Hungarian researchers. The article also discusses the fields of interest and individual achievements of Hungarian scholars, as well as the challenges Canadian Studies has faced.
Canadian Studies in the Czech Republic and Central Europe
Authors: Sparling Don
Published: October 2020

This article surveys the development of Canadian Studies in Czechoslovakia/the Czech Republic from 1985 (the year the first such course was offered at a Czech university) down to the present. It also deals with the wider context of the development of Canadian Studies in Central Europe under the aegis of the Central European Association for Canadian Studies, established in 2003 with its Secretariat located at Masaryk University, Brno. In both the Czech Republic and the wider region, the late 1990s saw a steady growth in Canadian Studies, fostered by financial support from the Canadian government and outreach activities by Western European Canadian Studies associations. The first decade of the twenty-first century saw an explosion of activities - many new courses and degree programmes, conferences and specialized seminars, international projects, publications, the launching of the Central European Journal for Canadian Studies. The century’s second decade, however, has witnessed retrenchment, the result of systemic changes in higher education systems and the Canadian government’s cancellation of all support for Canadian Studies activities in 2012. Nevertheless, in both the Czech Republic and Central Europe, Canadian Studies continues to enjoy a significant and respected presence in the higher education sphere.
Scarcity Strategy in Crowdfunding: An Empirical Exploration of Reward Limits
Authors: Yang Lusi , Wang Zhiyi , Hahn Jungpil
Published: October 2020

Scarcity-based marketing strategy has been prevalently implemented in reward-based crowdfunding in the form of reward limits, whereby campaign creators restrict the number of backers for each reward tier. This study uncovers the effect of reward limits on eventual and concurrent funding performance. Specifically, we performed campaign-level and campaign day–level analyses on a unique data set from a dominant crowdfunding platform. At the campaign level, we determined that setting reward limits at the beginning of a campaign is beneficial, with the number of limited reward tiers exerting an inverted-U-shaped relationship with campaign performance. Further exploration of different forms of reward limits suggests that the scarcity effects largely originate from limited edition and price discount rewards. At the campaign day level, we determined that incorporating new limited edition rewards is helpful for attracting new contributions, whereas depleted price discount rewards will demotivate subsequent contributions. In addition, the goal-directed mechanism in crowdfunding plays an influential role in shaping scarcity effects. Our findings highlight the importance of considering backer-as-consumer needs in crowdfunding campaign design and the dynamics of campaign attribute changes in the fundraising process. Our findings also provide important practical implications for platform operators, campaign creators, and marketers.
Blockchain Governance—A New Way of Organizing Collaborations?
Authors: Lumineau Fabrice , Wang Wenqian , Schilke Oliver
Published: October 2020

The recent emergence of blockchains may be considered a critical turning point in organizing collaborations. We outline the historical background and the fundamental features of blockchains and present an analysis with a focus on their role as governance mechanisms. Specifically, we argue that blockchains offer a way to enforce agreements and achieve cooperation and coordination that is distinct from both traditional contractual and relational governance as well as from other information technology solutions. We also examine the scope of blockchains as efficient governance mechanisms and highlight the tacitness of the transaction as a key boundary condition. We then discuss how blockchain governance interacts with traditional governance mechanisms in both substitutive and complementary ways. We pay particular attention to blockchains’ social implications as well as their inherent challenges and limitations. Our analysis culminates in a research agenda that explores how blockchains may change the way to organize collaborations, including issues of what different types of blockchains may emerge, who is involved and impacted by blockchain governance, why actors may want blockchains, when and where blockchains can be more (versus less) effective, and how blockchains influence a number of important organizational outcomes.

Oblique astigmatism and field curvature measured with light-field imaging
Authors: Ferreira Flávio P. , Sousa Marco A. , Duarte Moisés A. S. , Bret Boris P. J. , Nunes-Pereira Eduardo J.
Published: October 2020

The testing of astigmatism and field curvature of an optical system with light-field imaging is proposed. The method consists in measuring the depth map, obtained with a plenoptic camera, of the image of a test pattern formed by the optical system. To demonstrate the accuracy of the method, the virtual image formed by a plano-convex lens was tested. The resulting depth map was compared with the sagittal and tangential foci distances calculated with the Coddington theory. The proposed method could be applied to the quality testing of ocular optics, including eyeglasses, eyepieces, virtual reality goggles, and augmented reality devices.
