Authors: Maguire Mary Beth R. , White Anne
Published: April 2021

Background and objective: The COVID-19 pandemic has placed a significant increase for the need of high quality, high fidelity simulation practices to replace limited clinical experiences. Repetitive experiential practice is a training strategy used among professionals to bridge theoretical concepts to action. Furthermore, immediate repetitive experiential practice in a simulation environment is a novel approach that holds promise for learners to improve their response to critical conditions through increased faculty guided reflection. This study aimed to explore student attitudes regarding an immediate repeat of a simulation as a first step to explore training effectiveness.Methods: Students enrolled in a complex health baccalaureate nursing course participated in an immediate repeat of a septic shock simulation. An interpretive phenomenological approach was utilized to better understand undergraduate nursing students' lived experience of learning through a repeat septic shock simulation.Results: Three themes emerged: Appreciation of Knowledge, Awareness of Skill, and Awareness of Attitudes.Conclusions: Learners found an immediate repeat of the simulation a valuable teaching strategy. Participants described a growing sense of differentiating priorities when managing a patient in septic shock. The immediate repeat simulation was deemed impactful to the learners’ knowledge, skills, and attitudes. This is a viable option for educators to incorporate at a time when forced to utilize simulation experiences to replace limited clinical opportunities.

En este artículo presentamos hallazgos de un estudio con enfoque etnográfico sobre actividades emocionales en el trabajo cotidiano de docentes secundarios de distintos contextos educativos de Santiago, Chile. Utilizando la estrategia de shadowing, identificamos dos conjuntos de actividades emocionales: las primeras, que denominamos actividades emocionales emergentes, responden a demandas imprevistas e impostergables de sus estudiantes que los/as docentes deben resolver inmediatamente para continuar con su labor. En segundo lugar, están las actividades emocionales vinculares, que permiten a docentes conocer y construir una relación con sus estudiantes. En tercer lugar, recogemos las implicancias que tienen para los/as docentes estas actividades emocionales, en términos de su complejidad, el trabajo y tiempo involucrado, y el desgaste que producen. En la discusión planteamos que estas actividades son variadas, situadas e indispensables para el trabajo docente, pese a no estar reconocidas en las regulaciones basadas en la rendición de cuentas.
Dysbioza mikrobiomu jelitowego w anoreksji psychicznej
Authors: Janczy Agata , Landowska Magdalena , Kochan Zdzisław
Published: April 2021

Streszczenie

Anoreksja psychiczna (AN), zwana również jadłowstrętem psychicznym, to zaburzenie odżywiania, charakteryzujące się poważnym niedożywieniem, intensywnym strachem przed zwiększeniem masy ciała oraz zaburzonym obrazem własnego ciała. Choroba jest zależna od czynników biologicznych, psychologicznych i społeczno-kulturowych. Spośród różnych czynników biologicznych związanych z tym zaburzeniem, dużą uwagę przywiązuje się ostatnio do znaczenia mikrobioty jelit. Wyniki obserwacji dotyczących dysbiozy mikrobioty jelitowej u osób z anoreksją otworzyły nowe i obiecujące kierunki badań. Najnowsze obserwacje dotyczą zwłaszcza powiązania mikroorganizmów jelitowych z występowaniem funkcjonalnych zaburzeń żołądkowo-jelitowych związanych z anoreksją, z zaburzeniami lękowymi i depresyjnymi, a także z regulacją zachowań żywieniowych. Skład mikrobioty jelitowej różni się między pacjentami ze stwierdzoną anoreksją i osobami o prawidłowej masie ciała. Wynika to ze stosowania nieprawidłowej diety przez chorych, ale rośnie też zainteresowanie rolą mikrobioty jelit w patogenezie jadłowstrętu psychicznego, jej zmianami przez praktyki ponownego odżywiania, a zwłaszcza modulację składu mikrobiologicznego jelit za pomocą interwencji żywieniowych lub stosowania pre- i probiotyków jako środków wspomagających standardową terapię zaburzeń odżywiania. Następstwa zmiany sposobu żywienia w ramach leczenia AN są nieznane, co zwiększa potrzebę dalszych badań oraz pogłębiania wiedzy o osi mikrobiom-jelito-mózg. Jednak lepsza znajomość relacji mikrobiom jelit–mózg może być pomocna w usprawnieniu leczenia tego zaburzenia. W artykule przedstawiono aktualną wiedzę na temat przypuszczalnej roli mikrobioty jelit w patogenezie, przebiegu i leczeniu jadłowstrętu psychicznego.
Med en tydlig utgångspunkt i kristendomens synsätt och traditioner – om religionskunskapsämnets alkemi
Authors: Jonsson Linda , Månsson Niclas
Published: April 2021

I den här artikeln utgår vi från religionsämnets reformering 2011 med syfte att ringa in vad ett mer faktabaserat och rationellt förhållningssätt till andra religioner samt vad företrädet för kristendom kan betyda för ämnets fostrande roll och uppgift på gymnasie­skolan. För att förstå vad ämnets innehåll och syfte innebär som en del i formandet av den önskade samhällsmedlemmen, utgår vi från Popkewitz förståelse av alkemi och analyserar ämnet i ett historiskt och teoretiskt perspektiv. Genom en konceptualisering av ämnet över tid identifieras fyra vågor som format ämnet: en konfessionell våg, en objektiv våg, en osäker våg och en våg som benämns objektiv 2.0. Den första vågen karaktäriseras av ett väl avgränsat kristendomsämne med tydligt syfte och innehåll. Den önskade eleven är ett lydande och underdånigt barn med rötter i den kristna läran. Den andra vågen förstås bäst utifrån sin objektiva orientering. Den önskade eleven är vidsynt och tolerant med en god förståelse för kristendom och andra religioner samt existentiell pluralism. Den tredje vågen visar ett religionskunskapsämne med stor spännvidd och gränslöst innehåll. Den önskade eleven är vidsynt med god förståelse för religiös och existentiell mångfald förankrat i en kristen tradition och västerländsk humanism. Den kristna underströmmen når i och med den fjärde vågens inramning återigen ytan. Inramningen och avgränsningen sker genom ett fokus på faktakunskaper och ett vetenskapligt-rationellt förhållningssätt samt förståelse för religion som ett socialt snarare än ett existentialistiskt fenomen. Vi avslutar artikeln med att diskutera några didaktiska implikationer relaterade till reformen 2011.

Investment Decision Support Based on Interval Type-2 Fuzzy Expert System
Authors: Janková Zuzana , Jana Dipak Kumar , Dostál Petr
Published: April 2021

The decision-making process on investing in financial markets is a very complex and difficult task, mainly due to the chaotic behavior and high uncertainty in the development of the prices of investment instruments. For this reason, financial markets are increasingly using means of artificial intelligence, namely fuzzy logic, which is able to capture the nonlinear behavior.Fuzzy logic provides a way to draw definitive conclusions from vague, ambiguous, or inaccurate information.However, there are some drawbacks associated with type-1 fuzzy logic, so the type-2 fuzzy logic comes forward, which can work with greater uncertainty. Type-2 fuzzy logic works with a new third dimension fuzzy set that provides additional degrees of freedom and allows to model and process numerical and linguistic uncertainties directly. The paper applies type-2 fuzzy logic to the stock market with the aim to create a simple and understandable model for deciding on investing in investment instruments, which is important for investors in this area. The proposed type-2 fuzzy model uses return, risk, dividend and total expense ratio of ETF as input variables. The created system is able to generate aggregated models from a certain number of language rules, which allows the investor to understand the created financial model. Using type-2 fuzzy logic can lead to more realistic and accurate results than type-1 fuzzy logic.
Application of the Bayesian New Keynesian DSGE Model to Polish Macroeconomic Data
Authors: Sobieraj Janusz , Metelski Dominik
Published: April 2021

In the paper we estimate a simple New Keynesian Dynamic Stochastic General Equilibrium NK DSGE model on the basis of Polish macro data from the period 2000-2019. The model is specified similarly to Galí (2008) with the use of the Bayesian approach. The NK DSGE model combines the advantages of both structural models and time-series models and, therefore, shows a significant degree of alignment with empirical data. The Bayesian estimation is based on the prior distribution of the model input parameters, which are later compared with the posteriors. The results obtained allow for assessing the persistence of responses to technological, inflationary and monetary policy shocks. On the basis of the NK DSGE model, we formulate a perception of macroeconomic interactions, e.g. nominal interest rates’ association with inflation and the output gap. In other words, the NK DSGE model provides a better understanding of the relationship between interest rates, inflation and the output gap. This in turn makes it easier to understand the monetary policy response function.
Impact of Corporate Reputation Dimensions on Consumer Trust
Authors: Stravinskienė Jurgita , Matulevičienė Miglė , Hopenienė Rimantė
Published: April 2021

As global and local crises continue to destabilize stakeholders' trust in organizations, they need to find a long-term solution to the problem of declining trust. A critical marketing task for the sustainability of any business is to focus on the organization's reputation as a valuable, sustainable, and intangible asset of the organization. Growing trust in business is associated with corporate reputation that highlights company’s values and beliefs, shows the ways the company is trying to achieve its goals, to fulfil consumers’ expectations and its commitments.  In some cases, a company does not even have to try to earn stakeholder trust as this function is performed by corporate reputation that develops positive stakeholders’ attitude towards the company as a reliable subject in the relationship. An analysis of the organization’s reputation and stakeholder trust in the organization revealed a lack of a systematic approach to how the reputation of one organization affects the trust of customers. The research focuses on the issue of consumer trust, consumer being one of the most important stakeholders. Differences in the impact of corporate reputation dimensions on consumer trust are noticed in different sectors, which creates the need for in-depth study of the issue. The aim of the article is to estimate the impact of corporate reputation on consumer trust and to determine which dimensions of corporate reputation affect different types of consumer trust. Empirical research findings are based on the case of pharmacy network in Lithuania. The pharmacy network is chosen for analysis due to the phenomenon that has appeared in the market, i.e., over the years decreasing trust in companies of one sector (pharmaceutical, in this case) has been unjustly identified with the situation in the other sector (pharmacy), which results in difficulties faced when building corporate reputation.
Dynamic FPAA-based Mixed-Signal Processing Circuit for Thin-Film CdTe/Lead-Free Perovskite Photodetectors
Authors: Pandiev Ivailo M. , Aleksandrova Mariya P.
Published: April 2021

New photodetector structure combining thinned CdTe film with lead-free perovskite photoelectric film was produced and investigated. This setting of the CdTe thickness results in photodetector parameters’ competitiveness to the state-of-the-art in the field of advanced photoelectric materials. The device shows a promising sensitivity of ~40 μA/W, maximum responsivity of 10.6 mA/W at 460 nm, equal rise and fall times of 30 ms, and high linearity (maximum linearization error is less than 0.6 %). However, the optoelectronic performance of CdTe/lead-free perovskite structures integrated with signal processing circuit remains unexplored. For this purpose, Field Programmable Analogue Array (FPAA)-based mixed-signal processing circuit is developed for pulse width modulated electrical signal with duty cycle controlled by the illumination degree of the detecting photoelement. This novel approach guarantees a smooth change of the electrical output at a smooth change of the input illumination between the light and dark switching states and can be practically applied as a precise position detector of moving objects. The paper represents a synergistic connection between microelectronics, electronics, and signal technology.

Comparative analyses of skincare product advertisements in Georgian and English
Authors: Gvarishvili Zeinab
Published: April 2021

Across the gamut of media formats – from television to the Internet – beauty product advertising influences consumers on a daily basis. Each advertisement seeks to persuade potential buyers of the product's value, or even its necessity for the buyer's well-being and self-image. These techniques, sometimes manipulative in nature, affect consumers’ self-concepts. One of the signature strengths of the beauty advertisement lies in its ability to transform seemingly mundane objects into highly desirable products. In some cases, the beauty industry uses buzzwords and scientific words to convince consumers of a product's value; these linguistic devices describe the product's apparent capabilities and appeal to the consumer's ego by suggesting that the product will enhance the assets the consumer already possesses. All things considered, the present paper deals with a comparative study of skincare product advertisements in English and Georgian and focuses on the use of persuasive strategies, buzzwords and scientific terminology in the advertisements that manipulate and influence potential consumers.

Authors: Kovjanić Milorad , Vukadinović Predrag
Published: April 2021

Intellectual capital is of great value to profit-oriented organizations today. In the modern environment, the issue of strategic advantage is inseparable from the consideration of the issue of intellectual capital, bearing in mind that intellectual capital is a generator of economic value. In order for banks, as modern profit-oriented organizations, to achieve target performance, they need to know what their competitive advantage is, and to identify the necessary capacities and resources for sustainable business. The role of intellectual capital is crucial when it comes to the performances of modern banks, given the dynamic competitive environment in which they operate today. However, regardless of that, the literature that focuses precisely on the settings of these financial organizations is insufficiently represented and fragmented. This research, based on the application of the content analysis method, provides a structured review of the literature on the specifics of managing intellectual capital in banks. Further research could analyse the impact of intellectual capital on the performances of banks operating in the Republic of Serbia.

Published: April 2021

Information about the segments of a company is an important basis for making business decisions. In order for decisions based on segment information to be adequate, that information should be communicated in accordance with regulations. This paper is aimed at examining the adequacy of the segment information of listed companies in the Republic of Serbia and the Republic of Croatia and determining whether the volume of disclosed financial segment information is related to the company size and character of the audit firm. The research reveals that, in general, the disclosure of segment information is not fully in line with the International Financial Reporting Standard 8 - Operating Segments and that the joint-stock companies with a higher value of their total assets disclose financial segment information in more detail. However, there is no statistically significant difference in the amount of the segment information disclosed between the companies whose financial statements are audited by large audit firms and those that are the clients of other audit firms.

Authors: Chernets Myron , Kornienko A. , Chernets Yu. , Fedorchuk S.
Published: April 2021

The research of influence of sliding friction coefficient on durability is carried out for gear train containing steel wheels and metal-polymer gear trains containing polyamide gears reinforced with carbon and glass dispersion fibers. The teeth engagement conditions (two teeth pairs - single tooth pair - two teeth pairs) and the change of teeth tribocontact interaction conditions due to wear are also taken into account. The gear train containing the carbon-filled composite gear has the highest durability in comparison with other types in all ranges of change of sliding friction coefficient. The highest maximum contact pressures will be at the point of entry into the one-pair engagement. The change of initial maximum contact pressures in gear train due to tooth wear was also investigated and its regularities were established. The kinetics of the tooth profile wear was studied. It is established that the maximum wear will be at the point of entry into the one-pair engagement. Close to it will be the wear at the entrance into the two-pair engagement. The course of wear at different points of engagement for the studied gear trains containing steel toothed wheels and gear trains containing steel and composite gears is almost the same except for the point of the teeth exit from the engagement.

Authors: Mohamad Barhm , Karoly Jalics , Zelentsov Andrei , Amroune Salah
Published: April 2021

Hybrid mufflers are now commonly equipped to decrease vehicle noise and are a crucial tool for regulation of the acoustic system. In order to ensure optimum engine efficiency, the system is intended to dump the strength of the acoustic pulses generated from the engine, and the back pressure created by these systems must be held to a minimum. Typically, modern mufflers have a complex structure of chambers and flow paths. There are a number of mechanisms for sound dampening that operate to silence the sound flowing through a muffler and piping device. This research introduces an important approach to optimize the transmission loss of hybrid muffler Formula student race car (FS) by using both experimental and analytical methods. For this analysis, two methods of calculation were chosen. The muffler has a complex partition located within the muffler chamber, which is a perforated pipe. For the creation of the Finite Element Analysis (FEA) model in AVL BOOST solver and another commercial advanced design software, the muffler CAD file was developed. Experimental measurements using a two-load method validated the FEA model. Reliable tests were conducted to verify the design parameters and optimize the muffler's transmission loss (TL) after the model was checked. The findings of experimental and machine analysis are included in the paper. For different measurement methods, recommendations are made for achieving optimum transmission loss curves.

Authors: Kanbar Osama , Lantos Csaba , Pauk Janos
Published: April 2021

In vitro anther culture is the most commonly-used technology for doubled haploid production in wheat (Triticum aestivum L.) and various cereals. The technology application allows the genetic attainment of homozygous pure lines from heterozygous breeding material in a single generation, and has become a rapid alternative to the conventional breeding methods. This technology also contributes to more accurately assess QTL × environmental interactions and has been applied in: genetic researches for marker-trait association study, genomics and as a target for transformation, genetic engineering, gene mapping, and mapping of quantitative trait loci (QTLs). This paper reviews the most important factors that limit the efficiency of winter wheat (Triticum aestivum L.) anther culture, such as genotype dependency and albinism, in addition to other affecting factors including the collection time of tillers and physiological growth environments of plants. Factors that improve the efficiency of wheat anther culture in mitigating both genotypic dependency and albinism have been included in this review, too, for example, genetic improvements by following a strategy to realize this purpose through using responsive breeding material for crossing, application of convenient stress pre-treatments (cold pre-treatments, heat shock treatment, colchicine, hormones, and chemicals) to induce androgenesis, and improvement of the composition of anther culture media and culture conditions. We have also highlighted the methods of chromosome doubling for the haploid wheat produced by anther culture androgenesis, such as spontaneous chromosome doubling or use of colchicine and anti-mitotic chemicals at an early stage of anther culture or as root immersion treatment.

Authors: Denić Dimitrije , Bošković Goran , Pavlović Angelina , Jovičić Nebojša
Published: April 2021

In recent years, there has been an increase in the production of textiles and clothing, which is the result of an increase in the global population and an improvement in living standards. The consequence of this fact is the unlimited use of resources for the needs of the production process of textiles and clothing, as well as an increase in the amount of generated textile waste, which is currently not treated adequately. For the textile industry to have a chance in the future to take advantage of environmental, economic and social opportunities that it is currently unable to do, it is necessary to transform the current, linear system into a circular system. The paper presents the possibility of implementing the basic principles of the circular economy in the textile and clothing industry. According to the principles of the circular economy, the textile industry is based on the realization of four activities: elimination of unwanted substances and release (emission) of microfibers, increasing the utilization of clothing, improving the recycling sector, efficient use of resources and switching to renewable sources.

Authors: Ul Islam , Chaudhary Manjula
Published: April 2021

The common perceptions about tourist destinations often hold even in the absence of facts and evidences. This research is an attempt to analyze the ground behind generic perceptions about tourism attractiveness of Kashmir valley. This has been done through primary survey of most important stakeholders; the visiting tourists. The data collected from 370 tourists has been used to deconstruct tourism attractiveness into different parameters and an Index of Destination Attractiveness has been prepared to understand the importance of each parameter to overall attractiveness. The evidences support the common perception that natural attractions play very important role in tourism attractiveness of valley but valley lacks other tourism motivators and falls short on most of the hygiene factors. These findings can be used to increase the attractiveness of valley by working on weak areas and the Index developed for the study can be used as a standard tool for continuous monitoring of attractiveness.

Em tempos de pandemia global, todos os setores têm passado por uma reorganização física, estrutural e metodológica; com isso, a educação superior avança rapidamente para a significação do processo de ensino-aprendizagem. Nessa perspectiva, este artigo pretende relatar experiências da educação remota no Ensino Superior em um centro universitário da cidade de São Paulo (SP). Em decorrência da pandemia por Covid-19, o ensino remoto foi viabilizado para dar continuidade ao processo de formação. Por meio das narrativas autobiográficas sugeridas por Connely e Clandinin (2016) é possível evidenciar as diversas facetas desse processo transitório educacional. As narrativas são decorrentes de avaliações educacionais por meio de formulários online, reuniões gravadas em salas virtuais e vídeos depoimentos, além das narrativas das pesquisadoras. As experiências vivenciadas nesse novo espaço, onde cada um, de forma isolada, dá continuidade ao seu processo de trabalho nas diversas esferas como gestores, coordenadores, docentes, e alunos evidenciam nuances singulares de um processo de significação. Dessa forma, a prática reflexiva dos atores desse cenário compõe uma teia de experiências que são galgadas e descobertas dia a dia. O artigo pretende trazer contribuições para um ensino superior remoto de qualidade, viabilizando possibilidades no processo de ensino-aprendizagem na qual os alunos são o cerne de todas as decisões.

Adaptation of the Beliefs about Well-Being Scale to the Spanish population
Authors: San Martín García Jesús , Perles Fabiola , García Martín Miguel Angel , Canto-Ortiz Jesús
Published: April 2021

El estudio de la felicidad y el bienestar está recibiendo cada vez más atención en diferentes campos. Las investigaciones recientes sobre el bienestar se han centrado en profundizar en la concepción del individuo sobre la experiencia del bienestar. McMahan y Estes (2011a) crearon una escala que evalúa las concepciones legas del bienestar en base a cuatro dimensiones: la experiencia de placer, la evitación de la experiencia negativa, el autodesarrollo y la contribución a los demás. El objetivo de este estudio fue adaptar esta escala, Beliefs about Well-Being Scale (BWBS), a la población española. La muestra estuvo formada por 1.024 participantes de la población general con un intervalo de edad entre 17 y 87 años. El análisis factorial confirmatorio da como resultado una estructura de cuatro dimensiones, similar a la escala original, aunque en la adaptación de la escala los ítems disminuyen de 16 a 12. Los resultados del análisis de fiabilidad revelan índices similares a los de la escala original. Estos resultados confirman la validez de la Escala de Creencias sobre el Bienestar con población general en un contexto cultural diferente al del estudio original. Esto permitirá realizar estudios transculturales para analizar la influencia de la cultura en la percepción del bienestar

The study of happiness and well-being is receiving increased attention in different fields. Recent research into well-being has focused on delving deeper into the individual’s conception about the experience of well-being. McMahan and Estes (2011a) created a scale that assesses lay conceptions of well-being (BWBS) based on four dimensions: the experience of pleasure, avoidance of negative experience, self-development and contribution to others. The goal of this study was to adapt this scale, the Beliefs about Well-Being Scale, to the Spanish population. The sample consisted of 1,024 participants from the general population ranging in age interval from 17 to 87 years old. The confirmatory factorial analysis results in a structure of four dimensions, similar to the original scale, although in the adaptation of the scale the items decrease from 16 to 12. The results of the reliability analysis reveal indexes similar to those of the original scale. These results confirm the validity of Beliefs about Well-Being Scale with general population in a cultural context different from the original study. This will allow cross-cultural studies to analyze the influence of culture in the perception of well-being.
Adaptación transcultural y validación de la Brief Resilience Scale (BRS) para jóvenes chilenos

Published: April 2021

El estudio de la resiliencia como recuperación del estrés se ha extendido, y se requiere dar cuenta del desarrollo y las propiedades psicométricas de las escalas que permiten utilizarla. El objetivo fue adaptar transculturalmente la Brief Resilience Scale (BRS) y evaluar sus propiedades psicométricas en población joven chilena. Participaron en el año 2016, tres traductores, y 1,237 estudiantes de 18 a 24 años de una universidad de la zona Central de Chile, 60.8% mujeres y 39.2% hombres. Se consiguió la equivalencia lingüística y conceptual después de una doble traducción, retro traducción y de realizar las entrevistas cognitivas con la población diana. Se observaron dificultades en el ítem 2.  Del Análisis Factorial Exploratorio surgieron dos factores. Los índices de ajuste del Análisis Factorial Confirmatorio fueron adecuados: χ2 = 9.256(6), p = .160; CFI = .995; TLI = .988; RMSEA = .035, IC 90% [.000, .076]. El omega total .81. La estabilidad por ítem fue moderada y para la puntuación total, elevada. Las medias en general fueron menores en mujeres, pero similares entre grupos de edad. Hubo evidencia de validez concurrente y convergente. La versión chilena de la BRS puede ser útil para medir la resiliencia en jóvenes chilenos.

The study of resilience as recovery from stress has been extended, and it is necessary to account for the development and psychometric properties of the scales that allow it to be used. The aim was to report on the cross-cultural adaptation process and psychometric properties of the Brief Resilience Scale (BRS) in young Chilean population. In 2016, three translators, and 1,237 students between 18 and 24 years old from a university in the Fifth Region of Chile participated. Linguistic and conceptual equivalence was achieved after carried out a double translation, back-translation and cognitive interviews with the target population. Difficulties were observed in item 2. From the Exploratory Factor Analysis, two factors emerged. In the Confirmatory Factorial Analysis, the fit indexes were suitable: χ2 = 9.256(6), p = .160; CFI = .995; TLI = .988; RMSEA = .035 CI 90% [.000, .076]. Total omega was .81. The stability per item was moderate; and high for the total score. Means were generally lower in women than in men but similar among age groups. It has evidence for concurrent and convergent validity. The BRS Chilean version might be useful for measuring resilience in young Chileans.
De militære bibliotekerog hærordningen af 1867
Authors: De Hartyani Marton
Published: April 2021

For nogen tid siden blev min opmærksomhed henledt på, at et udvalg i 1867 havde behandlet spørgsmålet om en sammenslutning af Det kgl. Garnisonsbibliotek (KGB) med enten Det kgl. Bibliotek (KB) eller Universitetsbiblioteket (UB). Dette blev som bekendt ikke realiseret, men jeg satte mig for at undersøge baggrunden for sagen nærmere. Der er skrevet meget lidt om de militære biblioteker i Danmark og mest i annalistisk form. Bortset fra oversigtsartikler i Håndbog i Bibliotekskundskab og Nordisk håndbog i bibliotekskundskab er litteraturen forfattet af militære, som gennemgående ikke har været ødsle med brug af kilder. I Rigsarkivet er Hærens Arkiv nu en afdeling, og her findes Krigsministeriets og de forskellige våbenarters (korps) og militære institutioners arkiver. De rummer rige og uudnyttede fonds - hvis man ellers har tid og tålmodighed til at finde rundt i det sindrige krigsministerielle arkiveringssystem, men der er også meget store huller, hvad bibliotekerne angår.
Statens Avissamling i Århus
Authors: Larsen Svend
Published: April 2021

»Avisplagen« - det udtryk brugte Statsbibliotekets overbibliotekar Vilhelm Grundtvig i 1910 i en status over pligtafleveringen til Statsbiblioteket, Det kgl. Bibliotek og Universitetsbiblioteket i København.1 Grundtvig mente, at den store mængde (»en syndflod«) danske tryksager nemt kunne blive en dødvægt. Bibliotekerne ville fa store samlinger, som nok ville blive kilder for »bogarkæologien«, men som ville tage kræfter fra mere presserende nutidige opgaver. Han tilkendte nok aviserne stor værdi som kilder til oplysning om og forståelse af samfundet og dets udvikling. Men avisernes form og størrelse gav særlige problemer med indbinding og opbevaring, og han så derfor frem til, at aviserne blev skilt ud fra bibliotekerne. Lidt ironisk er det, at netop Vilhelm Grundtvig blev øverste chef for den institution, som blev skabt for at fjern
Kalibrering af nabostøj: Kunsten at finde en fælles standard
Authors: Veng Adam , Petersen Sandra Lori , Sørensen Thea-Maria
Published: April 2021

Denne artikel baserer sig på antropologisk interventionsforskning blandt beboere i en etagebygning med nabostøjsproblemer. Den illustrerer, hvordan udbredelsen af nabostøjsproblemer i Danmark knytter sig til hjemmets særlige betydning som et sted for dyrkelsen af egne, private, ”indre” værdier og som et værn mod offentlighedens ”ydre.” Dette ”indre” fungerer ofte som beboeres standard for, hvordan deres naboers lydskabende adfærd bør justeres. I en sådan ”kalibrering” udvikler nabostøj sig ofte til nabokonflikt. I vores intervention undersøger vi mulige tilgange til at håndtere sådanne konflikter ved at give beboerne byggeteknisk viden om lydisoleringen i deres ejendom samt at facilitere, at de sammen lytter til lyde fra nabolejlighederne. I forflytningen af nabostøj fra problematisk, udefrakommende adfærd til et bygningsmaterielt forhold viser vi, at mens visse beboere fortsætter deres kalibrering i henholdtil egne, indre standarder, åbner andre beboere op for at ”re-kalibrere” deres håndtering af nabostøj i henhold til bygningens lydisolerende kvaliteter som en fælles, ydre standard.
