Re-Thinking Information Literacy in a Postgraduate Class at a South African Higher Education Institution
Authors: Noll Susanne Doris , Brown Cheryl
Published: July 2020

This paper explores the applicability of a new model of information literacy, SCONUL, developed in the global North, to the South African higher education academic library context with all its enormous challenges of accessibility, transformation, basic education and intellectual awareness. Based on a case study of a postgraduate class in a commerce faculty, the paper draws on a survey and focus groups with students and interviews with lecturers to explore perceptions of information literacy and digital literacy as 21st-century skills that students need to be successful in their studies and the world of work. The findings show that whilst students exhibit confidence (through personal internet confidence) in terms of information literacy, they are not as skilled as they believe themselves to be. They also have a narrow notion of the concept. There are also contradictions in the understanding of the concept of information literacy between librarians, students and lecturers.

Published: July 2020

The aim of this study was to establish the impact of the North-West University’s language policy on its library’s print collections. It analyses the languages represented by books held by the North-West University Library and Information Services. The article further established the strategies used by the libraries to develop, preserve and promote African languages in support of the university’s language policy. The paper employed bibliometrics and focus group interviews to gather data. The findings revealed that books in African languages that were recognised by the university were difficult to get on the market. As a result, the majority of books accessioned by the libraries were in English, followed by Afrikaans, and relatively few books in Setswana, and Sesotho. The study is the first of its kind focusing on language policy and academic libraries in South Africa. It is valuable to both policy makers and librarians in their endeavours to develop sizeable African language collections in support of the curricula and research. Among the recommendations is that African language departments at various universities should collaborate with libraries to start open access African language journals, and publish them through the institutional repositories.
“Sitting There—Cool and Reading”: Results of a Reading-for-Pleasure Programme with Grade Seven Namibian Learners
Authors: Kirchner Emmarentia
Published: July 2020

This article explores the way in which a Namibian initiative to provide time in the school curriculum for engagement with reading may be developed into a practical reading programme. Based on principles of self-determination theory and expectancy value theory, as well as the work of Kimberly Safford about reading for pleasure, enabling physical and social classroom contexts that promote reading for pleasure was explored in a Namibian context. Viewing reading as part of a variety of literacy practices, different forms of reading as well as a variety of reading activities were integrated in the programme. The article reports on this process by documenting learner views on the reading programme. The programme was implemented with 48 Grade 7 learners in an urban, primary school in Namibia. The primary sources of data included eight focus group interviews, as well as a questionnaire which evaluated the reading programme. The results indicate that the implementation of the principles of the programme regarding choice and variety of texts stimulated the rediscovery of the joy of reading. Learners recommended that in future programmes digital reading activities should be further developed. There was a strong focus on the educational value of reading throughout. Furthermore, the merit of responding to texts in writing was pointed out. While learners agreed that the sharing of views regarding reading experiences built understanding of texts and was motivating, social reasons for reading seemed complicated and reading ability was regarded as a personal matter. The article concludes that, similar to other research findings, attention to reading for pleasure is important in developing reading motivation. The value of the study is situated in the use of views of Namibian learners towards the development of guidelines for similar programmes, as well as in the illustration of useful strategies for building a reading culture in schools.
Information Literacy Education: Perceptions, Proficiencies and Experiences of First-Entering Students at TUT
Authors: Molepo Cynthia Manamedi , Bopape Solomon
Published: July 2020

For students to master information literacy skills, they must attend Information Literacy Education (ILE) offered by academic libraries. This study adopted both quantitative and qualitative research approaches using a questionnaire and focus group interviews, respectively, to investigate the perceptions of the concept “information literacy”, “students’ skills to use library resources”, and “students’ familiarity with different library resources” of first-year students at the library of the Polokwane campus of the Tshwane University of Technology (TUT), South Africa, all before and after attendance of the ILE session, as well as to analyse their experiences of the ILE programme which they had attended. The study found that most of the first-entering students had a different perception of the concept “information literacy” in relation to its usage in the academic Library and Information Science (LIS) environment. The questionnaire findings further showed that the students had no skills in using library resources and were not familiar with library resources before they attended the ILE programme. However, the findings from the focus group interviews showed that, after they had attended the ILE session, they became familiar with some of the library resources, and their abilities to use those resources positively improved from novice to advanced and proficient users of information. It is therefore recommended that ILE for students be continuous so that students do not forget or lose focus of what they have learned in the formal ILE programmes. To encourage students’ participation, the attendance of ILE should be compulsory for all first-year entering students across all faculties at the TUT.

Authors: Nyasulu Chimango , Chawinga Winner , Chipeta George
Published: July 2020

Governments the world over are increasingly challenging universities to produce human resources with the right skills sets and knowledge required to drive their economies in this twenty-first century. It therefore becomes important for universities to produce graduates that bring tangible and meaningful contributions to the economies. Graduate tracer studies are hailed to be one of the ways in which universities can respond and reposition themselves to the actual needs of the industry. It is against this background that this study was conducted to establish the relevance of the Department of Information and Communication Technology at Mzuzu University to the Malawian economy by systematically investigating occupations of its former students after graduating from the University. The study adopted a quantitative design by distributing an online-based questionnaire with predominantly closed-ended questions. The study focused on three key objectives: to identify key employing sectors of ICT graduates, to gauge the relevance of the ICT programme to its former students’ jobs and businesses, and to establish the level of satisfaction of the ICT curriculum from the perspectives of former ICT graduates. The key findings from the study are that the ICT programme is relevant to the industry. However, some respondents were of the view that the curriculum should be strengthened by revising it through an addition of courses such as Mobile Application Development, Machine Learning, Natural Language Processing, Data Mining, and LINUX Administration to keep abreast with the ever-changing ICT trends and job requirements. The study strongly recommends the need for regular reviews of the curriculum so that it is continually responding to and matches the needs of the industry.
Barriers to High School Learners’ Online Information Behaviour in Ghana
Authors: Nsibirwa Zawedde , Kankam Philip
Published: July 2020

The Internet has provided many opportunities for learners to access online information to expand their knowledge at a fast pace. Ghana, as one among many other developing countries, has tried to create Internet access and usage among high school learners; however, a number of factors have hampered this process. The study therefore investigates the barriers to high school learners’ online information behaviour in Ghana. Through a survey design, the study employed a mixed-methods approach to look into this phenomenon. A total of 350 participants comprising Grade 12 learners, heads of ICT departments (HICTDs), ICT teachers and librarians from three high schools were included in the study. Learners were sampled through the use of simple random and stratified sampling techniques. All heads of ICT departments, ICT teachers, and librarians were included in the study due to their small number and hence there was no need for selection. A semi-structured interview schedule and questionnaire were used as data collection tools to solicit responses from the participants. The study revealed that a lack of adequate Internet infrastructure at schools is a major barrier to high school learners’ online information behaviour. The study recommends the need to improve the Internet infrastructure at schools.

First Online Physics Olympiads between United Russian-American High-School Teams
Authors: Arzhannikov Andrey V. , Knyazev Boris A.
Published: July 2020

The article is dedicated to the twentieth anniversary of two Internet physics olympiads organized by the Physics Department of Novosibirsk State University, in which senior pupils from Russia and the USA participated. For the time when before the advent of popular social networks there were a few more years when the currently popular messengers were not yet widespread, the organization of such competitions was technically and organizationally far from a trivial task. It was also necessary to overcome the problem of different programs and different levels of school physics teaching in Russia and the USA, as well as the problem of the language barrier. All these tasks were successfully solved by the joint efforts of the Russian and American organizing committees, and in 1999 the competitions Novosibirsk – San Diego and in 2000 Novosibirsk – St. Petersburg – San Diego – Seattle were held. A successful invention that allowed equalizing the chances of teams and replacing interethnic rivalry with cooperation was the idea to hold competitions between international teams, consisting of an equal number of Russian and American schoolchildren communicating with each other via direct video communication. Sets of tasks were prepared for the olympiads, both ordinary, written, and video clips with tasks-demonstrations. The latter have been particularly successful in resolving the problem of the language barrier. The great help in conducting these two Olympiads was the many years of experience gained by NSU during the All-Siberian Olympiads and the idea of the demonstration tasks used in entrance examinations at the Physics Department of NSU. We present in this article both the content of the tasks of the Olympiads and the responses of the domestic and American press to the events described.

Authors: Baranov Grigory N. , Bogomyagkov Anton V. , Levichev Eugene B. , Sinyatkin Sergey V.
Published: July 2020

We study magnetic lattice and optimize parameters for the fourth generation light source SKIF (Russian acronym of Siberian Circular Photon Source) to be built in Novosibirsk. We consider several lattice cells to achieve both low emittance and large dynamic aperture. The resulting lattice provides the natural emittance of the electron beam of 75 pm for the beam energy of 3 GeV and the orbit circumference of 476 m. Only two families of chromatic sextupoles give the dynamic aperture and energy bandwidth enough for both good beam lifetime and simple effective injection.

A direct numerical simulation of the influence of a local energy release region on the development of the combustion propagation process in a high-speed flow of homogeneous fuel-air mixture (Н2 + air) is carried out. The mathematical model of the energy source describes the physical phenomena characteristic for pulsed energy supply using laser radiation. The energy supply and ignition are modeled taking into account a given kinetic scheme. The results on the spatial and temporal evolution of the ignition region are presented. The dependence of the position of the ignition region on the flow velocity is investigated.
Modes of Travelling Electromagnetic Waves within Cylinders
Authors: Kovalyov Alexander A.
Published: July 2020

An algorithm is proposed for numerical calculation of traveling electromagnetic wave modes for solid and hollow solid state cylinders. Complex eigenvalues are defined for angular parameters characterizing emissive modes and whispering gallery modes (WG-mode). The polar component imaginary parts of the wave vectors are found for all modes, including WG modes. The calculation is carried out for the fixed cylinder sizes. The field distributions are calculated inside the cylinders. The dependence of the mode parameters on the extinction coefficients of the cylinder material was studied. The ratio of the density of energy fluxes for the radial and polar directions shows a sharp change when passage from the emissive modes to WG modes.

Published: July 2020

No Brasil as queimadas são caracterizadas por extensas linhas de fogo de rápida propagação que causam a mortalidade de espécies da flora e da fauna. Para mitigar estes danos, políticas públicas foram implementadas. Para correto funcionamento delas,  entretanto, é necessário compreender a variabilidade do fogo e os elementos que o afetam para aperfeiçoar as estratégias de prevenção e combate. Neste sentido, este trabalho teve como escopo analisar a dinâmica das queimadas no Brasil, nos anos de 2003 a 2018, através da climatologia de precipitação e dos acumulados e das anomalias de focos de queima de vegetação.  Os resultados demonstraram que há três padrões espaciais de queimadas no Brasil que se relacionam com dois sistemas de precipitação: a Zona de Convergência Intertropical e a Zona de Convergência do Atlântico Sul. Na maioria dos estados foi detectada uma tendência de redução de uso do fogo. Para outros, uma estabilização das taxas de detecção. Apesar destes resultados, as detecções ainda têm maior ocorrência na estiagem, quando tendem a contribuir significativamente para a degradação ambiental e para o dispêndio do orçamento público em operações de combate. Cabe aos entes federativos investirem em atividades de fiscalização, de monitoramento, de educação ambiental e de manejo preventivo para reduzi-las.Space-Time Dynamics of the Burns in Brazil in the Period 2003 to 2018 A B S T R A C TIn Brazil, vegetation fires are characterized by extensive and rapidly spreading fire lines that cause the mortality of flora and fauna species. Public policies were implemented to mitigate these damages, and for their correct enforcement it is necessary to understand the variability of the fire regime and the elements that affect it to improve prevention and combat strategies. In this sense, this work aimed to analyze the dynamics of burning in Brazil from 2003 to 2018 through the accumulated number of active fires and their anomalies as detected in satellite images with the precipitation climatology. The results showed that there are three spatial burning patterns in Brazil that relate with two precipitation systems: the Intertropical Convergence Zone and the South Atlantic Convergence Zone. A tendency to reduce the use of the fire was detected in most states; some indicated a stabilization of detection rates. The detections are still more frequent in drought periods, when the fires tend to contribute significantly to environmental degradation and to public budget expenditure in combat operations. It is up to the federal and state governments to invest in activities of enforcement, monitoring, environmental education and preventive management to reduce the use of fire in the country.Keywords: Variability of fire, climatology precipitation, public policies, active fire.

Authors: Furrier Max , Da Silva Ivanildo Costa
Published: July 2020

The present article has as objective to analyse the interrelations between the relief, the lithology, the hydrography and the conspicuous evidence of tectonics on the area covered by the Araçaji 1: 25.000 chart, State of Paraíba, Northeast Brazil. The results showed the existence of anomalies in the study area, such as altimetry with disproportionate dimensions to the regional average, strong channel inflections, rectilinear channels and modified patterns in the drainage network influenced mainly by the local geological framework and possibly the Cenozoic tectonics. Allied to this qualitative analysis, morphometric indices were applied, for which the values obtained corroborate the tectonic influence in the area. The methodology used in this article requires a greater comparison to results obtained in other areas of the Atlantic continental border. Geomorfologia, morfometria e evidências de tectônica na Folha Araçaji, Borda Oriental da ParaíbaR E S U M OO presente artigo tem como objetivo analisar as interrelações existentes entre o relevo, a litologia, a hidrografia e a conspícua evidência tectônica da área da folha Araçaji na escala de 1:25.000, Estado da Paraíba, Nordeste do Brasil. Os resultados mostraram a existência de anomalias na área em questão, como altimetria com cotas desproporcionais à média da região, fortes inflexões na direção de canais, canais retilíneos e padrões modificados na rede de drenagem influenciados, principalmente, pelo arcabouço geológico local e, possivelmente, pela tectônica cenozoica. Aliados a essa análise qualitativa, foram aplicados índices morfométricos, nos quais os valores obtidos corroboram com a influência tectônica na área.

Published: July 2020

Neste trabalho apresentamos uma metodologia para detecção de possíveis efeitos geodinâmicos, utilizando dados GNSS, modelos de velocidade SIRGAS, Geológico e Geofísico. As observações GNSS foram processadas para obtenção da variação da coordenada vertical e horizontal. Os modelos de velocidade VEMOS2009 e 2015 serviram como base comparativa para verificar os resultados obtidos com o processamento GNSS. A partir do conjunto de vetores de velocidades das estações da Rede Brasileira de Monitoramento Contínuo (RBMC) obtidos do NNR-NUVEL-1A, estimaram-se os elementos definidores do movimento da placa SOAM. Em seguida, foram realizadas algumas análises e comparações com os vetores de rotação da placa SOAM obtidas pelo modelo APKIM2008. As análises conduzidas tiveram por base observações contínuas, desde 2007 até 2016, junto a uma porção de estações GNSS pertencentes à RBMC (estações SIRGAS-CON). Os resultados considerando os modelos de velocidade de SIRGAS mostraram que após o terremoto no Chile em algumas regiões do Brasil houveram efeitos geodinâmico. Em comparação aos modelos geológico e geofísico observou-se que o campo de velocidade definido no processamento GNSS conseguiu retratar a realidade, como caso de estudo foi considerado a estação de Imbituba. Detection and assessment of geodynamic effects on a portion of Brazilian GNSS stations A B S T R A C TThis work presents a methodology for detecting possible geodynamic effects using GNSS data, SIRGAS, Geological, and Geophysical velocity models.

Authors: Vlasenko N. G. , Teplyakova O. I. , Evseenko V. I. , Dushkin A. V.
Published: July 2020

The effect of treatment of crops with supramolecular complexes of tebuconazole with plant polysaccharides on the infection and germination of spring wheat grain of a new harvest was studied. The experiment (2018, 2019) was conducted on the crops of varieties Novosibirskaya 31 and Obskaya 2 in the forest-steppe zone of Western Siberia. Crops were treated in the earing phase with tebuconazole mechanocomplexes with licorice root extract (ratio 1: 5, 1:10) and arabinogalactan (1:10) with a flow rate of 0.5 kg/ha. There was a decrease in the development of spike septoria in Novosibirskaya 31 by 97.6-98.5%, in Obskaya 2 by 78.6-98.9%. The biological effectiveness of the application of commercial fungicide Folicur, CE (active ingredient tebuconazole, 250 g/l, consumption rate 1 l/ha) was at a comparable level – 98.5 and 96.8-99.6%, respectively. Tebuconazole complexes with plant polysaccharides proved to be effective in inhibiting black point disease of wheat. Annually, the number of affected wheat caryopses was 1.54 and 1.50 times lower in Novosibirskaya 31 variety and 1.4-1.2 times lower in Obskaya 2 variety in the crops protected by tebuconazole with arabinogalactan compared to the treatment with Folicur, CE. Treatment with mechanocomplexes contributed to the reduction of seed contamination with phytopathogens. Complexes of tebuconazole with licorice root extract and arabinogalactan reduced the rate of infection with helminthosporiasis by 3.8 and 1.7 times (Folicur, CE – 5.5 times). Annually, seed contamination with Fusarium spp. was 8.3 and 3.7 times lower than in the control due to crop protection measures ensured by tebuconazole with arabinogalactan and licorice root extract. In the variants with the use of mechanocomplexes, seed infection with Penicillium spp. decreased. The biological effectiveness of tebuconazole with licorice root extract (1 : 5) was 69.9%, with arabinogalactan (1 : 10) – 58.1%, Folicur, CE – 67.7%. The best germination rate (95.0 and 89%), exceeding that of the standard, was obtained when both wheat varieties were treated with a complex of tebuconazole with licorice root extract (1 : 5). The complexes of tebuconazole with licorice root extract and arabinogalactan created by the mechanochemical method aiming to protect wheat plants from leaf diseases can have a significant healing effect on the emerging grain, improving its sowing qualities

Published: July 2020

The paper presents the results of the study on the influence of various tillage systems on the weed infestation of soft spring wheat of the Siberian Alliance variety. The study was carried out in a long-term stationary experiment (20152019) preceded by bare and green-manured fallow (rapeseed, melilot) in Kemerovo region. The soil of the experimental plot is classified as leached, medium-textured, medium-humus, heavy-loam chernozem. The following soil tillage systems were studied: deep moldboard, deep combined, minimum combined and minimum moldboard. Weather conditions during the research period were varied. Insufficient water supply during the first vegetation period of soft spring wheat (seedlings – leaf-tube formation) was noted in 2015-2017, with HTC (hydrothermal coefficient) being from 0.37 to 0.56. Excessive water content was observed in 2018 (HTC = 2.41) and moderate hydration – in 2019 (HTC = 1.12). Weed infestation was different in the conditions of each year. The impact of the soil tillage system on the number of weeds during the growing season of common spring wheat accounted for 21.6-90.4%, and their share in the total aboveground mass of the phytocenosis was 39.9-68.3%. The segetal flora in soft spring wheat crops is represented by monocotyledonous and dicotyledonous species with all the studied tillage systems. The highest density of weed vegetation during the tillering phase of soft spring wheat was recorded with deep moldboard soil tillage system (control). A reduction in weed infestation by 2.3 times compared to the control was noted with minimum moldboard soil tillage system preceded by bare fallow, 1.6 times – preceded by green-manured fallow with rapeseed, and 1.7 times – preceded by green-manured fallow with melilot. The same trend was observed in the proportion of weeds in the total aboveground mass of the phytocenosis during the wax ripeness phase of soft spring wheat with deep moldboard tillage system (4.3%), deep combined (3.9), minimum combined (4.1), minimum moldboard (2.6%).

Published: July 2020

The possibility of increasing the yield of fodder-grain crops in single-species agrocenoses to provide livestock with nutritious highquality feed was studied. The results of field and laboratory studies (2016–2018) on the cultivation of traditional (barley, oats, spring and winter rye) and uncommon fodder crops (triticale, corn) sown as single crops in the forest-steppe zone of Trans-Baikal Territory are presented. The objects of the research were the following recognized varieties of the crops under study: local winter rye Zhitkinskaya, spring rye Onokhoyskaya, oats Metis, barley Anna, triticale Ukro, corn hybrid Obsky 150 CB. The experiment was conducted on meadow chernozem mealy-carbonate soil (light loam by particle size distribution). Poaceous fodder crops were assessed in terms of their adaptability to growing conditions, yield and nutritional value of grain. Their economically valuable characteristics were shown. On average over the years of research, when cultivating traditional and uncommon poaceous crops for fodder grain in single-crop sowings, triticale and corn had an advantage. The grain yield in the experiment was 3.0-5.8 t/ha, collection of fodder units – 3.39-6.13 t/ha, digestible protein 287-494 kg/ha, gross energy – 34.7-60.5 GJ/ha, availability of digestible protein – 85–77 g per one feed unit. Traditional crops were inferior to uncommon crops in terms of grain yield by 0.5-3.3 t/ ha, (on average for the variants of the experiment), feed units – by 0.99-3.73 t/ha, digestible protein – by 85-292 kg/ha, gross energy – by 0.99–35.7 GJ/ha.

The analysis of information sources of HACCP system used in the food industry for assessment of quality and microbiological safety of products is presented. The applicability of the principles of the HACCP system in the technology of producing a protein-carbohydrate composite as a feed product for cattle is analyzed. The research was conducted in 2018–2019 in Novosibirsk region. A brief description of the technology for producing a protein-carbohydrate composite in raw or dried form is given. The technology based on the HACCP principles comprised the control of raw materials, intermediate products, the final product and the operating modes of equipment that implement the technological process. The feed additive was obtained from wheat grains, cheese whey and wheat bran. The methods and results of the study of hazardous factors in individual operations of the technological process, actions to prevent their occurrence, and critical control points in the development of the technology are presented. A list of biological, physical and chemical potential hazards was compiled. Critical control points were established in the technological process. According to the HACCP plan, hazardous factors were monitored for each operation, indicating what corrective actions should be taken to maintain the limits of the controlled process parameters. The actions listed hereabove are aimed at developing a plan of measures to prevent potential hazards. The quality and safety control system developed on the principles of HACCP in the technology for producing a protein-carbohydrate composite enables one to control the quality and safety of the product during all stages of its production.

The results of studying the influence of the degree of kinship and genetic similarity of parental pairs on meat productivity of Hereford cattle are presented. An increase in homozygosity in herds of Hereford cattle in Siberia may reduce the effectiveness of breeding work. It was found that the selection of parental couples had a significant effect (p < 0.01–0.001) on the formation of offspring meat productivity. Cows from distant inbreeding and outbred (unrelated) parents were superior in live weight by 31–47 kg at the age of 3 and 5 years compared to closely related ones. The highest live weight ratios (16–66 kg) were observed in young animals obtained from outbred selection of parental couples compared to their peers obtained from closely related mating. Bullcalves from 8 to 15 months old, obtained from mating of unrelated parents, exceeded their peers from closely related mating by 105 g (14%), moderately related – by 87 g (11%) and distant by 69 g (9%). Low values of this indicator for the age-group of up to 18 months result from a large number of factors (genotype, maternal milk production, housing conditions) in the initial stage of organism formation. Bull-calves and heifers with an average degree of genetic similarity of parental couples at all ages had better live weight compared to their peers, due to heredity formed from both parents. A dispersion analysis of the data established a reliable effect (p <0.001) of the degree of genetic similarity of the parental pairs on the amount of live weight. The study of the degree of kinship and genetic similarity of parental pairs will allow to obtain the most accurate and reliable data on the breeding value of Hereford cattle of Siberian selection.

Authors: Dyagilev G. T.
Published: July 2020

The paper presents the results of the study and analysis of the epizootic process of anthrax among domestic animals in the Republic of Sakha (Yakutia) from 1853 to 2020. The following indicators of the epizootic process were used in the analysis: incidence rate, mortality and lethality. The object of the study comprised written reports of veterinarians of Yakutsk region to the governor about outbreaks of anthrax among domestic animals and people, quarterly and annual reporting data on the incidence rate and mortality of domestic animals, as well as statistical data on the number of farm animals in the specified period. The highest intensive manifestation of the epizootic process in cattle and horses during the study period was noted in the period until the 40s of the XX century. From the mid-forties, incidence and mortality rates were dynamically declining. The epizootic process of reindeer was characterized by an increase until the end of the 40s (1949), whereas from the 50s to the end of the 70s there was a decrease in the incidence and mortality rates. From 1980 to 1986, another increase in the epizootic process was recorded in the reindeer husbandry, followed by a decrease. Lethality of cattle ranging from 5 to 70% occurred in the period of 1946-1976, horses – in 1945-1993, deer – in 1949-1993. In other adverse years, starting from the official registration of anthrax to the mid-40s (1944-1946), it reached 100%. Overall, intensive manifestation of the epizootic process of anthrax dynamically decreased in the second half of the study period, with the exception of reindeer, in which it increased in 1980–1986 with a subsequent decrease.

"A tudományos tudás áramlásának mintázatai Magyarországon, 1770–1830” Tudománytörténeti Kutatócsoport 2019. május 28–29. napjain konferenciát szervezett Science between Tradition and Innovation:Historical Perspectives címmel az ELTE Szekfű Gyula Könyvtárában. A konferencián magyar, cseh, osztrák és német vendégek, valamint az ELTE BTK Történeti Intézetének munkatársai angol és német nyelvű előadásaihangzottak el. A konferencia fő célja az volt, hogy a mai tudomány- és kultúrtörténet egyik aktuális kérdéskörének, a hagyomány és innováció problémájának kelet-közép-európai kontextusait megvilágítsa.Az előadások többségében a kora újkori tudományosság gyakran átmenetinek minősített, 18. századi periódusára koncentráltak. A tematikus panelek és előadások a hosszú tizennyolcadik század történeti és elméletikereteit vizsgálták, különös figyelmet fordítva a fogalomhasználat, a tudományos gyakorlatok, a tudástermelés, a transzferfolyamatok és ezek szaktudományokra lebontott vonatkozásaira.
Bányászati és Erdészeti Főiskola Áttelepülése Selmecbányáról, 1918-1919

A Magyar Királyi Bányászati és Erdészeti Főiskola története 1735-re nyúlik vissza, ekkor alapították ugyanis a Bányatisztképző Iskolát. Az elkövetkező évszázadokban az Osztrák–Magyar Monarchia magyarrészén egyedüli felsőoktatási intézménnyé nőtte ki magát típusán belül. Az első világháború kezdetén európai hírű műszaki iskolának számított. A háború kirobbanása komoly törést okozott az iskola életében.Az utolsó tanórák 1928. október 18-án kezdődtek, de a tanévet már nem tudták befejezni, ugyanis hamarosan csehszlovák csapatok foglalták el a területet. A professzorok és a diákok meg akarták őrizni magyarállampolgárságukat, magyar intézményben kívánták munkájukat és tanulmányaikat folytatni, így összepakolták a holmijukat és Magyarországra költöztek át. A menekülés során számos nehézséggel találkoztak,míg végül az ún. „menekült egyetem” otthonra talált Sopronban.

A budapesti közgazdaság-tudományi kar alapításának kalandos története a 19. század közepéig nyúlik vissza. Jelen írás a régi századfordulótól vázolja az eseményeket, amelyek elvezettek az egyetemalapításig.1918-ban a kettős monarchia összeomlásának végnapjaiban csak egy aláírás választotta el a tervet a megvalósulástól. A tanulmány hosszabban tárgyalja ifj. Erődi-Harrach Béla Közgazdaságtudományi Egyetemcímű írását, amely az 1918-as kísérletnek, valamint az 1920-as alapításnak is az alapját képezte. Ugyanakkor máig ismeretlen maradt a szakirodalomban.

A debreceni egyetem 1925-ben a magyarországi gyermekmentő akció két protestáns szervezőjének, a svájci Carl Irletnek és a holland báró Willem Carel Adrien van Vredenburchnek adományozott honoris causacímet. Varga Zsigmond teológus professzor méltatásában kifejtette, mekkora szerepe volt Irlet lelkésznek a mentőakció megszervezésében és koordinálásában, milyen fontos szerepük volt a Svájcba került gyerekekneka magyarságkép politikai és nemzetgazdasági alakításában. Irlet kitüntetését Horthy Miklós kormányzó és Klebelsberg Kunó vallás- és közoktatásügyi miniszter hagyta jóvá.

Balogh Ferenc, a Főiskolai Énekkar (Kántus) felügyelő tanára (1880-1898)
Authors: Kovács Gergely
Published: July 2020

Balogh Ferenc, a nemzetközileg elismert egyháztörténész professzor csaknem két évtizeden keresztül a Debreceni Református Főiskolai Énekkar (Kántus) felügyelő tanáraként szolgált, egy jelentős változásokat hozó időszakban. Elkötelezett tevékenysége két fontos irányba mutat. Támogatta a kórus első hosszú távon működő karnagyának, Mácsai Sándornak a véglegesítését, és letette az énekkar történeti kutatásának alapjait, ezzel történeti távlatot biztosítva annak identitásához. Az énekes diákok által csodált ünnepi beszédei meggyőző erejével összegyűjtötte a szükséges anyagi alapot az ének- és zenetanári tanszék megalapításához. E szónoklatok elemzése adja a dolgozat gerincét, bemutatva a retorikai remekléseket követő tetteket is.
Pozsonyi Egyetem válságos időszakának történetéhez- 1914-1923
Authors: Kiss József Mihály
Published: July 2020

Az 1912-ben megalapított Erzsébet Tudományegyetem 1914 őszén a jogi kar megnyitásával kezdte meg működését. A bölcsészeti karon csak 1918 elején, az orvosi karon 1918 őszén kezdődtek meg az előadások. A cseh légió 1919. január 1-én bevonult Pozsonyba, és innen kezdve kétségessé vált az egyetem további működésének lehetősége. 1919 szeptemberében a csehszlovák állam lefoglalta az intézmény valamennyi ingatlanát az Erzsébet Tudományegyetemen, így a bölcsészeti karon és orvosi karon megszűnt az oktatás.E karok tanárai és diákjai Magyarországra menekültek. A jogi karon még 1921 nyaráig tovább folyt az oktatás, majd e kart is bezárták. Az egyetem mint menekült tanintézet, a kolozsvári, ugyancsak menekült egyetemmel együtt Budapesten folytatta tevékenységét. 1923-ban az egyetem végleges helyét Pécs városában nyerte el.
