Deep Mourning in Cinquecento Venice: Gioseffo Zarlino's lectiones pro mortuis
Authors: Chemotti Antonio , Schiltz Katelijne
Published: March 2021

This article investigates three voci pari settings by Gioseffo Zarlino, the lectiones pro mortuis that appeared in the Motetta D. Cipriani de Rore et aliorum auctorum (Venice: Girolamo Scotto, 1563). Although this collection contains motets, we argue that Zarlino's lectiones were intended as liturgical items for an Office for the Dead, celebrated as part of exequial rites. As such, they represent the first printed liturgical settings for the Office for the Dead in the Italian-speaking area. By analyzing liturgical sources as well as chronicles, we show that there was no tradition of setting the lessons pro mortuis in Italy, and that Zarlino's lectiones must have been a somewhat isolated musical experiment. We contextualize the settings within Zarlino's oeuvre, while also highlighting their relation to the contemporary repertoire of polyphonic lessons for penitential liturgies, most importantly lamentations—a genre that was published widely in the 1560s. In an attempt to reconstruct the social and institutional networks that might constitute the background to Zarlino's lectiones, we urge considering their author not only as a theorist and composer, but also as a polymath, a priest, and, ultimately, a devout Christian.
W. de Wicumbe's Rolls and Singing the Alleluya ca. 1250
Authors: Desmond Karen
Published: March 2021

A set of thirteenth-century parchment fragments, including the remnants of two rolls and one manuscript codex, preserves a largely unstudied repertoire unique to medieval England. In addition to a single motet and a setting of a responsory verse, the Rawlinson Fragments preserve twelve three-voice Alleluya settings. While polyphonic Alleluyas are well known from the continental Magnus liber repertoire, these insular Alleluya settings are quite different. Most significantly, while composed on the text and pitches of plainchant, they include newly composed texts in at least one voice—that is, they are polytextual chant settings. Aspects of their musical style certainly draw on other polyphonic genres—organum, conductus, and motet. This article presents the paleographical and codicological evidence that corroborates an early date for these fragments (in the 1240s), confirms their connection to Reading Abbey, and situates their repertoire within a broader context. My analysis points to intriguing points of overlap with both the plainchant prosula tradition and the Magnus liber organa and motets. It reopens broader questions about the copying and performance practices of liturgical polyphony, including previous suggestions that motet texts may have been sung within the performance of the Magnus liber organa, regardless of the scribal copying conventions that separated organum and motet in the surviving Magnus liber manuscripts. The article also considers the role of the Rawlinson Fragments’ main scribe, Benedictine monk W. de Wicumbe, who was active within the monastic communities of Leominster and Reading as a composer of plainchant and polyphony, and as precentor, most likely in charge of his community's musical life.
Historiografia litewska o układzie kiejdańskim (1655 r.)
Authors: Sliesoriūnas Gintautas
Published: March 2021

W artykule podjęto próbę prześledzenia, jak kształtowały się i zmieniały w litewskiej historiografii oceny układu kiejdańskiego, zawartego 20 października 1655 r. między Wielkim Księstwem Litewskim i Szwecją, zrywającego dotychczasowe więzi unijne, łączące Litwę z Koroną Polską. W tekście zwrócono też uwagę na pierwsze oznaki kształtowania się łagodniejszych ocen działalności inicjatorów zawarcia tego układu ze strony Litwy, które można zaobserwować już na długo przed powstaniem historiografii tworzonej w języku litewskim.

Published: March 2021

The first case of the novel coronavirus infection (COVID-19) in Peru was reported on March 6, 2020. As of September 7, 2020, about 700 000 cases of COVID-19 resulting in 29,976 deaths have been confirmed by the Ministry of Health. Among COVID-19 patients with co-morbidities, type 2 diabetes mellitus (T2DM) has been recognized as a risk factor for severe disease. Patients with T2DM may experience diabetic ketoacidosis (DKA) and hyperosmolar hyperglycemic (HHS) if infected with the coronavirus 2 (SARS-CoV-2). Regular blood analysis including arterial blood gas is essential in monitoring the care of patients with T2DM infected with COVID-19. We report five cases of DKA in patients with underlying T2DM that presented with severe COVID-19 infection.

Learning points:

COVID-19 may cause acute metabolic dysregulations in patients with T2DM.

It is important to monitor basic metabolic panel (BMP) and arterial blood gases (ABGs) in patients with COVID-19 since metabolic complications can develop unexpectedly.

Patients with T2DM develop an inflammatory syndrome characterized by severe insulin resistance and B cell dysfunction that can lead to DKA.
Polish and Lithuanian civil resistance in the painting of the 19th century: Kanutas Ruseckas and Vincentas Smakauskas
Authors: Ragėnaitė Vaida
Published: March 2021

Hopes to restore the independent state of Lithuania lasted throughout the 19th century and promoted ideas of civil resistance in Poland and Lithuania. The struggle for independence erupted through the uprisings of 1794, 1830-31, and 1863. While these attempts at armed resistance did not lead to the liberation of Lithuania nor Poland, they demonstrated the undying willingness to regain freedom. The role of artists grew up with the increasing repressions of the tsarist government. Paintings and poems became weapons in the fight against the tsarist policy of Russification. The paper focuses on the works that the painters, Vincentas Smakauskas (1797–1876) and Kanutas Ruseckas (1800–1860), done after the suppressed uprising of 1831. A research hypothesis is a statement that paintings produced in this dramatic period of history embodied secret symbolic meanings and represented ideas of civil resistance.

Complex Social Gradient in Life Expectancy in Costa Rica: an Ecological Study with 24-Million Person-Years Follow-Up
Authors: Fantin Romain , Delpierre Cyrille , Kelly-Irving Michelle , Barboza-Solís Cristina
Published: March 2021

Introduction. The knowledge of Costa Rica's situation regarding the social gradient in mortality is still incomplete. Methods. National Electoral Rolls, which included all adult Costa Rican citizens were used. The event was death between 2010 and 2018. The exhaustive final sample included 2,747,616 people for 23,985,602 person-years of follow-up. An ecological study at the electoral district level was performed. Results. A negative social gradient was observed in men and in women, in particular in urban area. A protective effect of rural areas compared to urban areas was revealed in men, but not in women. As a result, in men, the poorest districts of mixed/rural areas had similar life expectancy than the richest districts in urban areas. Conclusion. These results partially contradicted the international literature on socioeconomic inequalities. It demonstrates the importance of studying contexts other than high-income countries to better understand the social inequalities in health worldwide.
Multi-epitope peptide vaccine prediction against Newcastle disease virus using immuno-informatics approaches
Authors: Putri N. , Wulandari I. , Ernawati R. , Abdul Rantam F.
Published: March 2021

Newcastle disease is one of the most critical disease in poultry and wild birds, largely due to its high morbidity and mortality, as well as its worldwide distribution and threat of considerable economic losses to avian industries caused by Newcastle disease virus (NDV). The NDV can cause clinical signs varying from subclinical infections to 100% mortality, depending on the susceptibility of the host and the virulence of the virus. The virus is classified into velogenic (viscerotropic velogenic and neurotropic velogenic), mesogenic and lentogenic. The objectives of this study was to design a peptide vaccine using immunoinformatics approaches. In total, 12 NDV fusion proteins retrieved from NCBI database were aligned to determine the conservancy and candidate epitopes were analysed by predictions tools from Immune Epitope Database. Then the 3D structure of the conserved region was modelled using the Swiss Model and aligned using PyMol software. Two epitopes were predicted as a peptide vaccine for B cell (DKAVNVYTSSQT and NMPKDKEACAKAPLEA). This is a preliminary study of designing an epitope-based peptide vaccine against NDV, and we recommend further study to identify the interaction between these peptides with T cells and antibodies.

We captured mormoopids, phyllostomids, and vespertilionids in Honduras to collect bat ectoparasites. Two species of Spinturnicidae (Acari) are the first reports of this family in Honduras. One species of Basilia Miranda Ribeiro, 1903, and four of Streblidae are recorded for the first time in Honduras. With these results, the current species number of each family for Honduras are two species of Spinturnicidae, three of Nycteribiidae, and 48 of Streblidae. We compared the number of species of Streblidae and bats in Honduras to highly sampled countries in Central and South America. Clearly, more effort is still needed in Honduras, although this is the third attempt to study the bat ectoparasites in Honduras.

Esta investigación tiene como objetivo analizar si los perfiles y competencias profesionales en Periodismo, demandados por las empresas en España, se corresponden con los recogidos en el Libro Blanco de la ANECA o se han visto modificados, más de una década después, por el impacto de la era digital y la aparición de nuevas necesidades laborales. En un panorama como el actual, de cambios rápidos e impredecibles, se hacen necesarios análisis e investigaciones periódicas como este trabajo. La metodología elegida ha sido el análisis de contenido de las ofertas de empleo dirigidas a graduados en Periodismo en los dos portales de empleo más utilizados en España en el ámbito de los Recursos Humanos, Infojobs y LinkedIn, durante el mes de septiembre de 2017. Toda la información facilitada en las ofertas se sistematizó en dos categorías relativas a datos descriptivos del tipo de contrato y datos sobre competencias requeridas. Los resultados nos permiten concluir que las competencias profesionales que se exigen hoy en día, en el mercado laboral a los licenciados/graduados en Periodismo, difieren cualitativa y cuantitativamente de las competencias profesionales descritas por la ANECA en 2005. Las competencias más demandadas por las empresas responden a la emergencia de nuevos perfiles profesionales relacionados con la web 2.0. Sin embargo, también es cierto que las empresas no parecen tener claras cuáles son las competencias que debe tener un graduado en Periodismo

A abordagem histórico-cultural: concepções e desafios segundo as narrativas das professoras de uma Rede de Ensino
Authors: Jacinto Clarice Schöwe , Renders Elizabete Cristina Costa
Published: March 2021

Apresenta resultados de pesquisa que considerou a implementação da abordagem pedagógica com viés histórico-cultural numa rede de ensino do ABC paulista. Partiu-se da pergunta: como se apresenta a abordagem histórico-cultural nas narrativas de professoras numa rede de ensino que afirma ter o currículo orientado por esta abordagem? O objetivo foi levantar indicadores para a implementação da abordagem histórico-cultural, sendo ela caracterizada a partir das narrativas de quatro professoras desta rede. Metodologicamente, optou-se pela pesquisa narrativa, sendo a entrevista narrativa e a roda de conversa os instrumentos de coleta. As autobiografias narradas das professoras oportunizaram a reflexão sobre a prática pedagógica a partir do referencial composto por categorias como educação transformadora, dialogicidade, pensamento crítico, mediação e amorosidade. Como resultado, chegou-se a um inventário da abordagem histórico-cultural sustentado no tripé design teórico/ design político/design didático, sendo possível verificar a presença da trama conceitual freireana na prática destas professoras.

O presente ensaio tem como objetivo traçar possíveis compreensões sobre as contribuições psicanalíticas à atuação na clínica cardiológica a partir de uma breve articulação e discussão teóricas. Lançou-se mão de compreensões tais quais a inserção do analista no hospital, o corpo adoecido para a psicanálise e os principais aspectos subjetivos presentes na clínica cardiológica. Concluiu-se que o cerne das contribuições psicanalíticas à problemática é o oferecimento de possibilidade de acesso ao simbólico, diante de conteúdos difíceis de ser elaborados, que emergem a partir do processo de adoecimento.
Qualidade de Vida de Mulheres Negras com Câncer de Mama: Uma Revisão de Literatura
Authors: Santos Esthér Aparecida Silva dos , Araujo Tereza Cristina Cavalcanti Ferreira de
Published: March 2021

Há mais de duas décadas, a Organização da Mundial da Saúde propôs uma definição para Qualidade de Vida (QV) e, desde então, numerosas pesquisas têm sido desenvolvidas em diferentes especialidades. Caracterizada pela multidimensionalidade, subjetividade e dinamismo, a QV abrange diversos domínios da existência humana, incluindo-se fatores de natureza sociocultural, como gênero e etnia. Considerando a necessidade de ampliar conhecimentos específicos sobre QV, realizou-se uma revisão da literatura especializada, publicada entre 2014 e 2019, sobre QV de mulheres negras com câncer de mama. Para tanto, foram consultadas as bases BVS Psi, SciELO, MEDLINE/PubMed. Identificaram-se oito artigos, cuja análise apontou alguns indicadores relacionados à percepção negativa da QV: sintomas depressivos e ansiosos, idade inferior a 50 anos, estar em quimioterapia e tipo de câncer. Constatou-se, também, que bem-estar espiritual/religioso sobressaiu como fator associado a uma percepção de QV mais favorável. Concluiu-se que mais estudos são necessários, notadamente para fundamentar intervenções em Oncologia.
Habitar e repartir o espaço textual: a natureza delirante em Evando Nascimento
Authors: Losso Eduardo Guerreiro Brito
Published: March 2021

Resumo O trabalho vai se ater ao primeiro livro de Evando Nascimento, retrato desnatural (diários - 2004 a 2007), de 2008, lançado pela editora Record e caracterizado por Leila Perrone-Moisés como uma das obras da “literatura exigente” brasileira contemporânea. O artigo pretende analisar as diferentes séries de fragmentos dos quais o livro é feito e para os quais cada capítulo estipula uma regra variável. Nelas, a composição do todo apresenta uma condução singularíssima de partes e seções, especialmente na configuração epigráfica, na economia citacional, na titulação e no farto jogo com grafismos subvertendo convenções da escrita. Há uma densa reconfiguração do meio de exposição de um autorretrato diarístico no qual se mobilizam questões de espacialidade textual e ambiental e no qual se propaga, por conseguinte, a indecidibilidade entre textualidade e paisagem, humano e inumano, materialidade e imaterialidade, lucidez e delírio. Em suma, trata-se de uma ostensiva operação de desnaturalização do eu e do mundo.
Del poema que se inunda, devastado: Raúl Zurita. Dimensiones ecológicas, aproximaciones ecocríticas y episteme urbanoambiental

Resumen La presencia de una idea generalizada sobre nuestra evidente crisis ecológica global, ha suscitado, en el campo de las humanidades, una serie de reflexiones críticas, creativas y empáticas para con las acciones de denuncia ecológica, sosteniblilidad y preservación del medioambiente. Ante aquello, consideramos que la escritura poética reciente de Raúl Zurita (Santiago, 1950), presenta una serie de rasgos y cualidades susceptibles de ser relacionadas con las representaciones de la naturaleza y el medioambiente en tanto dimensiones ecológicas. A partir de una serie de aproximaciones teórico-críticas precedentes, pretendemos evidenciar el desarrollo de una imaginación estética de relación y crítica entre el ser humano y la naturaleza, para luego leer la expresividad poética de Raúl Zurita en tanto reflexión crítica sobre la naturaleza y el lenguaje, afín a la proposición conceptual de una nueva episteme urbanoambiental (Heffes), centrada en los imaginarios de denuncia ecológica, sostenibilidad y preservación.

Published: March 2021

ABSTRACT Introduction Dehydration has been described as one of the main factors of reduced performance in combat sports activities, leading to death in extreme cases. Objective To investigate the pre-training hydration status and changes in fluid homeostasis during two taekwondo training sessions. Methods Eighteen male college athletes (age 22.6 ± 3.37 years) were assessed. The study design aimed to reproduce the conditions of a 90-minute taekwondo training session, divided into three stages: a) warm-up exercises (20 min); b) poomsae (30 min) and c) technical training (40 min). The athletes had ad libitum water intake during training. To assess the hydration status we considered body mass (BM), the amount of liquid consumed and urine output, which enabled us to establish absolute and relative fluid loss in kg and percentage as well as the sweating rate. We also considered urine specific gravity (USG), urine color (U-COL), and subjective sensation of thirst (Sthirst) before and after the training session. Pre- and post-training results were compared separately in each session and between sessions. Results There was a significant difference (P<0.05) in pre-training BM between the two days of training. There was a significant difference (P<0.05) in the final BM on both days of the experiment. Most subjects had relative dehydration below 2%. A significant difference (P<0.05) was recorded pre and post training for U-COL and Sthirst, with the highest rates obtained at the end of each session. Participants always started training at a low dehydration status (USG >1,020g.ml-1). Conclusions The athletes tended to start the training sessions in dehydration status, which increases over the course of the training. Ad libitum water intake was not sufficient to balance fluid loss. Changes in fluid levels between sessions were similar.

Published: March 2021

ABSTRACT Introduction Swimming starts are an important component for decreasing the total race time, especially in short events. In this phase of swimming, the aim is to increase performance using many different techniques and starting platforms. Objectives The effects of height and slope of the starting block on kick-start performance were assessed in this study. Methods Six male competitive swimmers performed 24 kick-starts using four block settings: 65 cm & 75 cm flat and 65 cm & 75 cm sloped. Two-dimensional kinetic and three-dimensional kinematic data were analyzed, including average and maximum horizontal/vertical forces and impulses; reaction times; movement and block times; and take-off vertical/horizontal velocities. Two-way within-subject design ANOVAs were implemented to test the effects of block height and slope on the kinetic and kinematic variables. Results Block slope was the main factor affecting most of the dependent variables. Shorter block and movement times, greater average and maximum vertical forces, vertical impulse, and maximum horizontal force were found for the sloped settings. An inverse relationship was found between block height and 0-5 m times. Conclusion Based on the results, blocks with height of 75 cm and slope of 10° provided better results in swimmers’ performance in the block phase.

Published: March 2021

ABSTRACT Introduction Extreme conditioning training (ECT) has become a popular method, characterized by a wide variety of exercises. For good technical performance, practitioners must have good perception of the different parts of the body; however, it is not known whether this perception differs between practitioners and non-practitioners of ECT. Objective To analyze the perception of body dimensions among subjects submitted to an ECT session. Methods Adult men were divided into TRAINED (n = 10) and UNTRAINED (n = 10). All subjects were submitted to a combination of high-effort multiarticular exercises for a set period of nine minutes (“the largest possible number of repetitions” [AMRAP]). For the procedure of marking the body pattern, the subjects were scored in terms of acromioclavicular joints, waist and trochanter. Results Regarding the general perception of body size, the TRAINED and UNTRAINED groups were classified as adequate for each stage. In the dimension of body segments, there was an overestimation of the shoulder region in both groups (TRAINED Pre = 105.2 ± 8.37; Post = 117.23 ± 22.11 [ES = 0.79]; 30 min = 101.34 ± 14.21 [ES = 0.34] and UNTRAINED Pre = 96.72 ± 12.79; Post = 99.47 ± 12.17 [ES = 0.22]; 30 min = 111.05 ± 11.06 [ES = 1.27]). The perception of the waist region improved significantly after training (TRAINED Pre = 114.11 ± 16.4; Post = 117.7 ± 20.16 [ES = 0.20]; 30 min = 104.59 ± 11.46 [ES = 0.68] and UNTRAINED Pre = 114.66 ± 9.88; Post = 104.64 ± 12.87; [ES = 0.88]; 30 min = 108.36 ± 12.32 [ES = 0.57]). Conclusion ECT can promote better perception of body dimensions. In addition, the assessment of body size in active, but untrained individuals showed a better body perception, albeit a transitory effect.

Development of microsatellite loci and population genetics in the bumblebee catfish species Pseudopimelodus atricaudus and Pseudopimelodus magnus (Siluriformes: Pseudopimelodidae)
Authors: Rangel-Medrano José David , Márquez Edna Judith
Published: March 2021

ABSTRACT The Neotropical freshwater catfish Pseudopimelodus atricaudus and Pseudopimelodus magnus are two recently discovered species endemic to the Colombian Magdalena-Cauca River basin. In this study, a set of 13 microsatellite loci were developed by using next generation sequence technology to assess the genetic diversity and population structure in P. atricaudus and test for cross-species amplification in P. magnus. Both species exhibited high genetic diversity (P. atricaudus: Na: 9.000 - 9.769 alleles/locus, Ho: 0.760 - 0.804, HE: 0.804 - 0.840; P. magnus: Na: 12.8 - 5.4 alleles/locus, Ho: 0.638 - 0.683, HE: 0.747 - 0.755) compared to the mean levels of genetic diversity reported for Neotropical Siluriformes, and lack of genetic differentiation among sampling sites within the Cauca River (P. atricaudus: F’ST=0.013 - 0.017, P > 0.05, D’est= -0.004 - 0.023, P > 0.05; P. magnus: F’ST= 0.031, P= 0.055; D’est= 0.045, P= 0.058). This work is the first insight on the diversity and the population genetics of species of the family Pseudopimelodidae and provides a framework to further population genetic and conservation analyses needed in this poorly studied family at the microevolutionary level.

Published: March 2021

Abstract In vitro culture techniques are recognized as efficient strategies for large-scale plant production, as well as providing alternatives for plant conservation. In this study the micropropagation of Tarenaya rosea was established using petiole and foliar blade segments cultivated on MS medium with 6-benzyladenine (BA) and/or 6-furfurylaminopurine (KIN). The regeneration rate from explants was evaluated after 30-days in culture, as well as the proliferation rate from explant-derived shoots, reached after four subcultures performed at 30-days in culture. In vitro propagation occurred by both direct (DO) and indirect (IO) organogenesis. The highest regeneration rates by DO (50% to 100%) were reached on media containing only BA, while morphogenic calluses (IO) were mainly formed with BA+KIN. Explants on media with BA showed the presence of small black nodules on their surface, and histological analysis revealed the presence of trichomes with anthocyanin content. Elongation and rooting were reached on growth regulator-free MS. Acclimatization rates around 80% were achieved and the in vitro-regenerated plants were successfully maintained under field conditions. Results show significant morphogenetic potential of T. rosea from leaf explants, mainly when cultivated in the presence of 4.4 µM BA, providing a new alternative source of plant material for biotechnological and in vitro conservation studies.

Abstract We compared the functional diversity of community at edge and interior areas of an Atlantic forest fragment to test the hypothesis that higher functional diversity exists along edges - in consonance with their higher abundance and floristic diversity as compared to the interior of the forest. By considering a set of vegetative, reproductive and phenological traits and ecosystem service aspects of edge and interior environments, we defined plant functional groups using Cluster Analysis, followed by a silhouette width analysis, together with functional diversity indices of richness, divergence, evenness and dispersion. The main functional groups formed were similar between the edges and interior. Functional richness was the only index that demonstrated differences between edge and the interior. Alterations were perceived in relation to species richness and the Shannon index. Edge effects were not significant in the formation of functional groups. In contrast to our original hypothesis, similar groups were formed both along the edge in the interior - indicating that species played similar ecological roles in both environments, with similar responses to different environmental factors - so that forest edges were colonized by a series of different species that maintained diversity patterns similar to those found in the forest interior.
O tema da infância heroica na 'Eneida' de Virgílio: os casos de Ascânio-Iulo e Camila, a rainha dos volscos
Authors: Mota Thiago Eustáquio Araujo
Published: March 2021

O presente artigo tem por objetivo investigar as apropriações poéticas do tema da infância heroica a partir da construção dos personagens Ascânio-Iulo e da rainha volsca, Camila, na Eneida. Embora projetada na idade heroica, ou no passado pré-fundacional, a epopeia virgiliana revela importantes aspectos da percepção romana sobre as fases formativas conhecidas como infantia, pueritia e pubertas e sobre os respectivos papéis de gênero. Busca-se questionar em quais termos os heróis virgilianos performam ou transgridem essas etapas, seja pela excelência ou pelo desvio.
Jogos e brincadeiras infantis na educação ateniense do Período Clássico
Authors: De Sousa Luana Neres
Published: March 2021

O reconhecimento da importância dos jogos e das brincadeiras no processo de interação social e de aquisição do conhecimento realizado por crianças pequenas não é exclusividade das sociedades contemporâneas. Ao analisarmos textos gregos antigos, como as Leis, de Platão, observamos que essas atividades recebem importantes reflexões acerca de sua relação com o processo educativo do futuro cidadão ateniense. Além da documentação textual, brinquedos e brincadeiras infantis são retratados em cerâmicas do período clássico, especialmente nas choes, vasos de uso exclusivo de crianças e relacionados ao contexto das Antestérias. O objetivo deste artigo é analisar a maneira como os jogos e as brincadeiras são concebidos por Platão, nas Leis, bem como são representados em três exemplares de choes dos séculos V e IV a.C., visando compreender em que medida estas atividades estavam relacionadas ao processo educativo dos meninos atenienses deste período.
Becoming an Imagined Record: Archival Intervention in Autofiction
Authors: Cho Richard M.
Published: March 2021

Human rights are intricately tied to the practice of archivists, and the imperative to address the silence of the archive has been discussed in archival scholarship. After examining the evolution of archival intervention in arts (films, novels, plays, etc.), this article analyses the narrative components of two novels—W. G. Sebald's Austerlitz (2001) and Valeria Luiselli's Lost Children Archive (2019)—and demonstrates that certain works of autofiction are uniquely fit to become “imagined records.” Through the lens of “archival reading,” the article reveals these novels' narrative traits, such as their tendency to rely heavily on photographs, maps, and other iconography; their use of a specific type of narrator; and their intention to supplement the silence of the archive, the characteristics that facilitate the construction of imagined records. By delineating the ways in which these traits were implemented in the creation of an imagined record, the article paves a way for more imagined records to come in the future. Rooted in real sociohistorical traumas, these two novels expand the notions of evidence and the forces that shape archival theory and practice.
Maintaining Records in Context? Disrupting the Theory and Practice of Archival Classification and Arrangement
Authors: Trace Ciaran B.
Published: March 2021

The role and the associated practices of the archivist are attuned to notions of facilitation. Archivists facilitate people's engagement with the historical record by providing access to records in context: a context instantiated through archival classification, arrangement, and description. In the second of a two-part article, the author draws from the archival literature to present a historical overview of the factors that contributed to evolving notions of archival classification and arrangement from the 1960s to today. A review of the literature of this time frame provides its own context for understanding how, why, and through whose influence competing understandings and implementations of core classification ideas persist. In the process, the author highlights classification as a historically situated interpretive act, drawing attention to the implications of various disciplinary influences and analytical perspectives on the present status and future conception of, and possibilities for, the American archival profession.
The Low Duty Centrifugal Compressor Control System and its Impact on the Surge Pressure
Authors: Poljak Igor , Orović Josip , Knežević Vlatko , Vulić Jure
Published: March 2021

This paper presents an analysis of the low duty compressor for marine steam generators and its running conditions. The analysed low duty compressor was observed under three different running zones caused by a throttled flow towards main steam generators. All examples were explained according to real exploitation conditions. As the low duty compressor has the highest influence on the flame stability for the main steam generators while running, it is very important to observe the constant flow towards the main steam generators. Possible flow fluctuation implies instabilities which are explained in the article and the same have to be avoided in order to assure a reliable life span of the low duty compressor and smooth operation of the main steam generators. Furthermore, for preventing efficiency losses of a steam power plant, some methods for avoiding surge effects are emphasized and recommended.

Authors: Grbić Luka , Barić Mate , Cimera Karlo , Čurin Dragan
Published: March 2021

In this paper the main objective was to analyse water distribution market on Adriatic islands, mainly those without any water piping infrastructure. Those islands are mostly supplied by water carrying ships. The used methodology consisted of analysing, in last four years, the number of water deliveries and amount of precipitation in the research area. The analysis showed that the most critical situation occurs from June to September, when the number of residents grows and the amount of precipitation lowers. In order to avoid critical situations, like water reductions and draughts, important factors are pointed out which could lead to such situations and with proper precautions action can be avoided.
Iatrogenic blood loss due to daily laboratory testing and the risk of subsequent anaemia in intensive care unit patients: case series
Authors: Witosz Kamil , Wojnarowicz Olga , Krzych Łukasz J.
Published: March 2021

Introduction: Anaemia is associated with a wide range of negative outcomes. Diagnostic blood loss (DBL) may contribute to its occurrence. We aimed to evaluate DBL and its impact on haemoglobin (HGB) concentration and developing anaemia in the intensive care unit (ICU) patients. Methods: A study group comprised of 36 adult ICU patients. DBL during 7 consecutive, post-admission days was calculated. Anaemia occurrence was assessed using the WHO thresholds. Data on HGB and haematocrit (HCT) was subjected to analysis. Results: Upon admission, 24 (67%) patients were diagnosed with anaemia, on the eighth day 29 (80%) subjects (with 6 new cases). The median volume of blood collected was 143.15 mL (IQR 121.4–161.65) per week. No differences in DBL were found between the subjects with newly developed anaemia and their counterparts (p=0.4). The median drop of HGB (HbΔ) was 18 gL–1 (IQR 5–28) and the median drop of haematocrit (HtΔ) was 4.55% (IQR 1.1–7.95). There was no correlation between neither HbΔ and DBL (p=0.8) nor HtΔ and DBL (p=0.7). There were also no differences in HbΔ/HtΔ when age, gender or the primary critical illness were taken into account for the analysis (p>0.05 for all). The 7-day fluid balance was associated with haemoglobin drop (R=0.45; p=0.006). Conclusions: Anaemia is frequent in ICU patients. Diagnostic blood loss in our institution is acceptable and seems to protect patients against significant iatrogenic blood loss and subsequent anaemia. Dilutional anaemia may interfere with the results so before-after interventional research is needed to explore this interesting topic.
The Influence of Multi - Cultural Higher Education on Economic Development
Authors: Baykan Hüseyin
Published: March 2021

The aim of this study is to specify the contribution of universities and university students to social and cultural structure and economic development of the country. Representatives of public organizations, tradesmen and economic organizations were given semi-structured interview. The data were analyzed through “content analysis”. The findings indicate that, students from foreign countries do not spoil the cultural structure of the country. However, due to the economic conditions in their countries, students from the third world countries are willing to stay on the island. If employed, their employment might have negative effects on the social and cultural structure of the island in long-term. Another finding revealed that the universities do not receive sufficient contributions from the state and the scholarships awarded are insufficient.

Education during a State of Emergency
Authors: Topalska Radoslava
Published: March 2021

The accessing changes in the world order provoke fields such as education, work, and in general human lives. The pandemic caused by the spread of Covid-19 affected an extremely large part of the Earth, including the Republic of Bulgaria. Pupils and students had to switch to distance learning, being more precise go-to distance learning in an electronic environment. This was unexpected for us all - parents, students, and especially teachers. The teachers are the ones who have extremely difficult task of dealing in a very short time with the selection of (and possibly acquaintance with) appropriate software, as well as to master information and communication technologies, in most cases, and they may have never been trained in. This situation also provoked the study, which found a place in this report. It was targeted at the very beginning of the forced isolation, including the closure of educational institutions, in the Republic of Bulgaria - in the period from March 18 to April 10, 2020. A logical choice in this state of emergency was the way of conducting it - an electronic survey.

Published: March 2021

The research compares perfectionism as a personal quality and its value-semantic barriers during the acquisition of the first professional skills in order to provide psychological support for social adaptation. It is argued that timely diagnosis of such condition can clarify the necessary psychotherapeutic interventions. A program of point studies to present new empirical data and formulate new relationships between structural and nuclear characteristics of the individual was formalized. The classical quasi-experimental approach of D. Campbell was used for analysis. The achieved results can help to form a more critical scientific view on the studied problem.
