En la bárbara gentilidad de aquella tierra: Indígenas y diplomacia borbónica en la frontera del Misisipi en las tres últimas décadas del siglo XVIII
Authors: Álvarez Cuartero Izaskun , García Malagón Alejandro
Published: June 2021

Este artículo analiza los modos de relación que los grupos indígenas de las zonas fronterizas de Florida occidental y Luisiana entablaron con los enclaves españoles del curso inferior del río Misisipi durante las tres últimas décadas del siglo XVIII. Para ello revisamos el uso que se hizo del regalo como instrumento diplomático y de control, de compra de voluntades y de prestigio, destinado a modelar las pautas de comportamiento del indígena en una estrategia de contención de las autoridades españolas frente a la política de frontera desplegada por el gobierno estadounidense.
Las ligas femeninas ante el alcoholismo y la salubridad en el México posrevolucionario, 1934-1946
Authors: Ramírez Chicharro Manuel
Published: June 2021

El objetivo de este artículo es analizar cómo las ligas femeninas de distintos Estados de la República de México se dotaron de entidad jurídica y se constituyeron en sujeto político reivindicativo que, junto a la lucha por los derechos de las mujeres, reivindicó otro tipo de mejoras materiales como reducir las altas tasas de alcoholismo y mejorar las condiciones de salubridad en sus localidades. Concretamente se estudiarán aquellos grupos y asambleas impulsados por o vinculados al Frente Único Pro Derechos de la Mujer (1935-1940) y al Bloque Nacional de Mujeres Revolucionarias (1940-1946) durante los gobiernos de Lázaro Cárdenas y Manuel Ávila Camacho.

Published: June 2021

Purpose The “Act on Hospice and Palliative Care and Decisions on Life-Sustaining Treatment for Patients at the End-of-Life” was enacted on February 3, 2016 and went into effect on February 4, 2018 in Korea. This study reviewed the first year of determination to life-sustaining treatment (LST) through data analysis of the National Agency for Management of Life-Sustaining Treatment.Materials and Methods The National Agency for Management of LST provided data between February 4, 2018 and January 31, 2019 anonymously from 33,549 patients. According to the forms patients were defined as either elf-determinants or family-determinants.Results The median age of the patient was 73 and the majority was male (59.9%). Cancer patients were 59% and self-determinants were 32.1%. Cancer patients had a higher rate of self-determinants than non-cancer (47.3% vs. 10.1%). Plan for hospice service was high in cancer patients among self-determinants (81.0% vs. 37.5%, p < 0.001). In comparison to family-determinants, self-determinants were younger (median age, 67 years vs. 75 years; p < 0.001) and had more cancer diagnosis (87.1% vs. 45.9%, p < 0.001). Decision of withholding or withdrawing of LSTs in cancer patients was higher than non-cancer patients in four items.Conclusion Cancer patients had a higher rate in self-determination and withholding or withdrawing of LSTs than non-cancer patients. Continued revision of the law and education of the public will be able to promote withdrawing or withholding the futile LSTs in patients at end-of-life. Further study following the revision of the law should be evaluated to change of end-of-life care.
Bone Tools at the Late Pre-Hispanic Site Boyo Paso 2 (Sierras of Córdoba, Argentina)
Authors: Medina Matías , Pastor Sebastián
Published: June 2021

The aim of the article is to assess the role played by bone tools at Boyo Paso 2 (Sierras of Córdoba, Argentina), an open-air site interpreted as a basecamp seasonally occupied by mobile mixed foraging and farming people c. 900–700 years BP. The results suggest that diverse activities were carried out on-site, including hunting or warfare, tool production, food processing and rituals. Bone tool analysis may enable reconstruction of the technological level, social organization, and cultural attitude towards the environment among people neither wholly foragers nor wholly farmers, a category for which archaeology currently lacks sufficient archaeological understanding and that merits further research.
Chronological Modelling of the Chalcolithic Settlement Layers at Tell Yunatsite, Southern Bulgaria
Authors: Boyadzhiev Yavor , Boyadzhiev Kamen , Brandtstätter Lennart , Krauß Raiko
Published: June 2021

This article publishes a new series of radiocarbon dates from Tell Yunatsite, Southern Bulgaria. Context-based excavations undertaken over a large surface area, as well as a small test trench, provided a long stratigraphic sequence (11 ‘building levels’) covering a large part of the Chalcolithic period in Thrace (5th millennium BCE). Bayesian statistics and Gaussian Monte Carlo Wiggle Matching were employed to achieve a fine chronology for the multilayered tell. Implications and problems on the application of the calibration curve for the Late and Final Chalcolithic in Bulgaria are also discussed.

Authors: García Rivero Daniel , Taylor Ruth , Umbelino Cláudia , Cubas Miriam , Barrera Cruz María , Díaz Rodríguez Manuel J.
Published: June 2021

An intact archaeological context named Locus 1 has recently been discovered at Dehesilla Cave (southern Spain). The ritual funerary deposition consists of a complete pottery jar with part of a human calvarium over the mouth, and was occulted by large stone blocks. This paper offers a presentation of the new data provided mainly by the stratigraphic, osteological, pottery, lithic and radiocarbon analyses. A systematic review of the relevant evidence in the Iberian Peninsula during the Early Neolithic (c. 5600–4800 cal BC) provides a context for this finding and supports its interpretation with reference to several possible anthropological scenarios.

Pobreza multidimensional en España. Una aplicación de la metodología de Alkire y Foster. 2008 - 2015
Authors: Corbelle Cacabelos Fernando , Troitiño Cobas Ángela
Published: June 2021

Considerando la pobreza como un fenómeno que limita la capacidad de desarrollo de las personas en todas sus dimensiones, se aborda su estudio multidimensional tomando como referencia la metodología de Alkire y Foster (2011). Su aplicación al ámbito español, usando la Encuesta de Condiciones de Vida (ECV2008-ECV2015), genera nueva evidencia sobre la medición de la pobreza multidimensional y su sensibilidad a los criterios de identificación, contribuyendo al debate sobre la pertinencia de esta metodología como referencia.
Los resultados permiten concluir el incremento de la pobreza multidimensional en el período estudiado, tanto en incidencia como en intensidad, con independencia del umbral seleccionado. Se observa la existencia de cambios en los perfiles de pobreza. Disminuye el gap por género, aunque la proporción se mantiene más alta en las mujeres. La población de 50-64 años sufre la mayor incidencia en todo el periodo, si bien el mayor incremento (disminución) se da en los jóvenes (mayores). Los hogares con niños presentan una clara dualidad: dos adultos con uno o dos niños muestran los menores niveles de pobreza, mientras el resto sufren los mayores niveles. Las parejas sin niños son las únicas que muestran mejoría. Por regiones, se observan incrementos generalizados, a excepción de Extremadura y Galicia que reducen sus índices de pobreza. Los mayores incrementos se dan en Cantabria, Murcia y Canarias. Las dimensiones educación, económica y trabajo son las que más contribuyen a la pobreza, presentando la primera una clara mejoría en el período y la última un destacado incremento.
Eficiencia innovadora en el sector servicios: el caso de Uruguay
Authors: Brida Juan Gabriel , Ladós Valentina , Sicilia Gabriela
Published: June 2021

Este estudio analiza la eficiencia técnica en términos de innovación de las empresas del sector servicios en la economía uruguaya. Para ello, se utilizan los datos provenientes de la Encuesta de Actividades de Innovación 2010-2012 de la Agencia Nacional de Investigación e Innovación (ANII). En una primera etapa, se estima el nivel de eficiencia de cada empresa mediante un modelo de Análisis Envolvente de Datos, incorporando los inputs y outputs relacionados con la actividad innovadora de las empresas. Los resultados revelan que, a pesar de los esfuerzos realizados en materia de inversión en innovación, los resultados son aún muy pobres. En promedio, las empresas analizadas podrían aumentar su producción en materia de innovación en un 44,5% dado los recursos invertidos. Posteriormente, se explora la relación entre la eficiencia innovadora y diversas características de las firmas. En este sentido, se encuentra que las empresas medianas presentan menor eficiencia que las pequeñas y grandes. Asimismo, las empresas que no solicitaron apoyo estatal para financiar las actividades de innovación muestran un mayor nivel de eficiencia que aquellas que sí solicitaron. Los resultados pueden ser de interés tanto para los responsables del área de innovación de las empresas, como para las instituciones que brindan apoyo en materia de innovación (como la ANII), ya que aportan evidencia sustantiva para mejorar la orientación de la estrategia innovadora a seguir por las empresas del sector servicios.
Transmisión de volatilidad en el Mercado Integrado Latinoamericano (MILA): una evidencia del grado de integración
Authors: Fuentes Vélez Mariana , Pinilla Barrera Alejandro
Published: June 2021

Este trabajo da cuenta del avance en la integración del Mercado Integrado Latinoamericano (MILA), mediante el estudio de la relación dinámica entre las volatilidades de los mercados que lo componen: Colombia, México, Perú y Chile. Para esto, se usaron datos, desde 2002 hasta 2018, de los índices accionarios representativos de cada una de las bolsas de valores de los países miembros. Debido a las características particulares que tienen las series financieras, como la no estacionariedad y la varianza dinámica a lo largo del tiempo, se aplican las técnicas de series de tiempo, específicamente, los modelos de la familia GARCH con un enfoque multivariado que permitan capturar la relación existente entre los mercados. Se encontró que individualmente las series son procesos integrados de orden 1 y presentan efectos ARCH. Si bien la existencia de interdependencia de volatilidad entre los mercados es latente y varía a lo largo del tiempo, los resultados de este estudio muestran que esta relación no presenta un aumento significativo después de la conformación del MILA. Así, pese a que los mercados están interrelacionados, la interdependencia no es tan fuerte y, por lo tanto, cada uno de los mercados mantiene fuerte independencia del resto. En otras palabras, la integración no se ha alcanzado completamente y, con ello, las ventajas de esta solo se han evidenciado parcialmente en cada una de las bolsas.

IS THERE A RELATIONSHIP BETWEEN THE INSTITUTIONAL SUCCESS OF UNIVERSITIES IN WEBOMETRIC RANKING SYSTEM AND THEIR POPULARITY ON FACEBOOK? A HOLISTIC CASE OF TURKISH UNIVERSITIES
Authors: YILDIZ Orkun
Published: June 2021

Purpose: Social media is among the most important digital platforms that bring individuals and institutions together. In the digital age, universities use social media to share news and updates about the institution, research, teaching, and social activities. Perhaps, one of the most critical indicators of success in the university account management process in social media might be the number of followers. Hence, this study examined whether there is a relationship between universities’ Facebook official account follower counts and universities’ position in the Webometrics university success ranking scale, which is an indicator of universities' institutional success. Method: The present study focused on 161 universities located in Turkey. The official Facebook accounts of these institutions and ranking success position in Webometrics were examined by using two different secondary data sets from 2017. Findings: The assumed relationships were tested through correlation analyses by using SPSS 20 statistical software. The results showed that there was a significant relationship between universities’ follower counts on Facebook pages and Webometrics ranking scores. Originality: This study would be pioneering research that can contribute to the literature on the relationship between the success of higher education institutions in Webometric ranking and the popularity of official accounts in a social media channel. Considering the results of this research, it is expected that the top managers of higher education institutions and universities will contribute to institutional value management.

Kur’an Çevirilerinde Akıbet Lamı
Authors: ATEŞ Avnullah Enes
Published: June 2021

Arap dilinde kelime türlerinden biri olan harfler cümlede tamamlayıcı bir unsur olarak kullanılır. Sahip oldukları anlamlar kullanıldıkları isim veya fiille birlikte ortaya çıkar. Hangi harfin ne anlama geldiği ve kullanıldığı yerde nasıl bir manayı ortaya çıkardığı önemlidir. Zira harflerin birden çok anlamı olabilmekte ve kullanıldığı fiil veya isme göre bu farklılık arz edebilmektedir. Cer harfleri de bahsi geçen niteliklere sahip harflerdendir. Sahip oldukları anlamları ilişkili oldukları fiil ve isimlere taşımaktadırlar. Farklı birçok anlama gelebilen bu harfler içerisinde, Kur’an çevirisi noktasında sorun teşkil edebilecek bazı harfler bulunur. Bunlardan biri lâm harfidir. Lâm harfinin genel kullanımında temlik, ihtisas ve ta‘lil (gerekçe) anlamları bulunur. Ayrıca bu harf, bazen bir eylemin ileride netice verecek olduğu durumu ifade etmek için de kullanılabilmektedir. Lâm harfi bu anlamda kullanıldığında kendisine akıbet lâmı denilir. Akıbet lâmı, görünüşte ta‘lil gibi algılanabildiğinden birçok hatalı çeviriye sebep olabilmektedir. Durum bazen aklen izahı mümkün olmayan çevirilerle karşılaşılmasına kadar varmaktadır. Bazı Türkçe meallerde karşımıza çıkan bu çeviri sorununa bu çalışmada dikkat çekilecek ve soruna çözüm önerileri sunulacaktır. İlgili harfin tanımı ve örnekleri ortaya koyulduktan sonra Kur’an ayetlerindeki kullanımları bazı Türkçe mealler çerçevesinde incelenecektir. Sorunlu görülen çevirilerin düzeltilmesi adına alternatif çeviriler ortaya koyulacaktır.
Hadislerin Kur’an’a Arzının Suiistimali
Authors: ÇAKIR Furkan
Published: June 2021

Hz. Peygamber'in (s) irtihali ile beraber İslâm dünyasında hayatı anlamlandırma çabası güden pek çok farklı anlayış ortaya çıkmıştır. Hiç şüphesiz bu anlayışların temelinde Kur’an ve hadis metinlerini anlama gayreti yatmaktadır. Nassları anlama çabası kimi zaman yapıcı; kimi zaman ise yıkıcı bir karakter arz etmektedir. Sözü edilen anlamlandırma çabaları, modern zamanlarda hadisler üzerinde daha fazla yoğunlaşmıştır. Nitekim hayatını Hz. Peygamber döneminde olduğu gibi yaşama iddiasında bulunan zümreler de, modernitenin etkisine kapılarak Peygamber döneminden herhangi bir ize ihtiyaç duymayan söylemler de hadisi-sünneti önemsemişlerdir. Bu çalışmada, gelenekte izleri bulunan; fakat modern zamanda Kur’ancı-Mealci söylemin suiistimali ile farklı bir yöne evirilen “Kur’an'a aykırılık” fikri üzerinde durulacaktır. Zira erken dönemde isnat üzerine yoğunlaşan tenkit faaliyetleri, zamanla cerh ve ta‘dîl uzmanlarının yetişmesini ve bu sayede isnada arız olabilecek kusurların belli bir oranda bertaraf edilmesini temin etmiştir. Rivâyet değerlendirmelerinde isnat tetkiklerine paralel olarak, metin endeksli tenkitler de görülmeye başlanmıştır. Metin endeksli tenkit metotlarından biri de “Hadislerin Kur’an’a arzı” metodudur. Bu çalışmada İslâm ilim geleneğinde önemli bir yer tutan, fakat modern dönemde metodolojisine aykırı bir boyuta ulaşan “hadislerin Kur’an’a arzı”nın suiistimaline değinilecektir.
SIGNIFIKANSI LABEL KEHORMATAN ISRAEL DALAM 1 PETRUS 2:9-10 BERDASARKAN TEORI IDENTITAS SOSIAL (SIT)
Authors: Hasibuan Serepina
Published: June 2021

Topik mengenai pembentukan identitas sosial pembaca dalam surat 1 Petrus hangat diperbincangkan oleh para ahli. Dua monograf yang layak didiskusikan adalah karya Paul A. Himes dan David G. Horrell. Himes mengklaim bahwa foreknowledge Allah berperan dalam pembentukan identitas pembaca 1 Petrus (penelitian terhadap kata πρόγνωσις dan προγινώσκω). Sedangkan Horrell mengklaim bahwa kata Χριστιανός pada 4:16 berperan sebagai label yang membentuk identitas pembaca 1 Petrus. Berbeda dengan keduanya, penulis berpendapat bahwa Petrus membentuk identitas sosial pembacanya melalui Perjanjian Lama khususnya pada 1 Petrus 2:9-10. Masifnya penggunaan materi PL dalam 1 Petrus dan label kehormatan Israel yang diasosiasikan kepada pembaca menjadi pertimbangan dasar dari asumsi tersebut. Makalah ini akan menjelaskan bagaimana 1 Petrus 2:9-10 signifikan sebagai dasar pembentukan identitas sosial pembaca. SIT dipandang sebagai metodologi yang efektif untuk membuktikan hal tersebut. Dari hasil penelitian ini terlihat bahwa peranan Perjanjian Lama lebih luas yakni sebagai dasar pembentukan identitas sosial pembaca

Published: June 2021

Çocuk edebiyatı yapıtları; okul öncesi dönemden başlayarak çocukla tanıştırılması gereken, çocuğun görsel algılarını devindirebilen sanatsal uyaranlardır. Bu yapıtlar çocuğa düşsel ve sanatsal bir dünyanın kapılarını açabilmektedir. Çocuk edebiyatı yapıtları çocuğu sanat eğitimi bağlamında da destekleyebilecek çok boyutlu uyaranlardır. Yapıttaki resimlerle tanışan çocuk belleğinde uyaranları soyutlaştırabilir, yaşama ilişkin iletileri yazınsal metinler ve resmin gücü yoluyla belleğinde anlamlandırabilir. Bu çalışmanın amacı; resimli çocuk edebiyatı yapıtlarını çocuğun sanat eğitimine katkıları bağlamında incelemektir. Bu amaç doğrultusunda Leo Lionni’nin “Yoğun Bir Yıl”, “Frederick”, “Yüzyüz”, “Pezzettino”, “Dünyanın En Büyük Evi”, “Yeşil Kuyruklu Fare”, “Alexander ve Oyuncak Fare” adlı yapıtları Prof. Dr. Sedat Sever’in çocuk edebiyatı yapıtlarını inceleme ölçütleriyle incelenmiştir. Veriler; yapıtların çocuğun sanat eğitimine katkısı bağlamında değerlendirilmiştir. Elde edilen veriler “betimsel çözümleme” yöntemiyle incelenmiştir. Çalışma sonucunda incelenen yapıtlardaki resimlerin estetik özellikler taşıdığı ve çocukta resim yapma isteği uyandırabilecek bir yapıda olduğuna ilişkin veriler elde edilmiştir. Yapıttaki görsel uyaranların ve kurgulanan yazınsal metinlerin çocuğu sanat eğitimi sürecinde destekleyebilecek bir nitelikte olduğu düşünülmektedir.

The effects of some metal (II) ions on the natural pyrrhotite dissolution in hydrochloric acid solutions were studied Our results suggest that the rate of pyrrhotite dissolution increases in the presence of Sn2+ ion. Ions like Ni2+, Co2+, Cu2+, zn2+ do not appear to have any effect on pyrrhotite dissolution in hydrochloric acid solutions. The magnitude of the activation energy (23.31 kJ mol-1) is in agreement with a mechanism controlled by a diffusion process.

The work presents experimental data about new analogs of ammonium tetranitro-diamine Co (III) complex (Erdmann complex) with hexamethylenetetramine (hta). The base complex obtained, NH4[CO(NO2)4(hta)]2, as well as the Erdmann complex, present practical importance for agriculture. They contain nitrogen under cationic, anionic, and molecular form and Co (III) as a micronutrient and serve as a source of other micronutrients through the replacement of NH4+ with other complex cations. Some of these complexes are soluble in water, others are hardly soluble and nonhygroscopic. Their efficiency in fertilizing was demonstrated by us experimentally.

Published: June 2021

We describe isolated teleostean teeth found in no association with the jaw bone. The specimens have been recovered in Late Cretaceous marine deposits of the Vivian Formation in the Peruvian Sub-Andean Region. The deposition sequence from where the teeth come is interpreted as a shallowing-upward sequence of low salinity. The fish material is identified as Enchodus aff. E. gladiolus based on the presence of a small but well-developed post-apical barb, an anterior cutting edge, the crown is symmetrical in cross-section, have a sigmoidal profile, and bears strong ridges (=striations). The Peruvian material differs from the typical E. gladiolus teeth in having a faintly serrated anterior cutting edge which is absent in most specimens referred to E. gladiolus. We also highlight that taxonomic assignments made based on isolated teeth must be taken with care. Despite scarce, the material recovered denotes that the marine units of Peru can give valuable information about the Pacific fish fauna during the Late Cretaceous.

A common male sexual disorder is erectile dysfunction which has multidimensions. In this fast-moving world, it is prominently seen in lots of males. There are many causes for Erectile Dysfunction, one of the major causes is the improper supply of blood to the penile organ. That may be due to vasoconstriction or blockage in the internal pudendal artery which supplies oxygen to the penile organ. A simulated model of the internal iliac artery to the internal prudential artery is designed and a flow simulation is done using Solid works software. The Computed Tomography of a male subject is obtained and a three-dimensional model of the abdominal artery is extracted using MIMICS (Materialize Interactive Medical Image Control System) software. By making use of the measured dimensions from the three-dimensional image. The 3D models (Normal condition, Abnormal condition with blockage, and Abnormal condition with constrictions) are designed and the Flow analysis is done in Solid works software. By the end of the study, we came to a conclusion that at normal temperature and pressure, the simulated normal volumetric blood flow at the internal pudendal artery is 6.88701e-09 m3/s and for abnormal cases the simulated volumetric blood flow is 2.6107e-09m3/s.

Published: June 2021

Esta pesquisa teve como objetivo verificar quais são os instrumentos gerenciais utilizados pelas empresas de peças e acessórios automotivos, localizadas na cidade de Bayeux/PB, na tomada de decisão. Para isso, foram constatadas 123 empresas abrangentes nesse setor, e, como amostra, 31 respondentes. Os dados foram coletados a partir de um questionário estruturado, e a pesquisa teve abordagem predominantemente quantitativa. Na organização dos dados, o estudo utilizou a estatística descritiva. Os resultados constataram que as empresas focam a tomada de decisão baseada na experiência do proprietário; ressalva-se, também, que grande parte das organizações não utiliza a contabilidade na tomada de decisão, pelo fato da informação contábil não refletir a real situação da empresa e/ou o gestor desconhecer sua utilidade. Os instrumentos gerenciais mais empregados na tomada de decisão são os controles operacionais, planejamento tributário e estratégico, e os menos utilizados são as demonstrações contábeis, métodos de custeio e outros instrumentos gerenciais. Conclui-se que, apesar de certa resistência dos gestores em querer gerenciar a organização com a própria intuição ou experiência, percebe-se que há a utilização de alguns instrumentos gerenciais.

Published: June 2021

A qualidade da informação contábil tem sido discutida com muita intensidade quanto à utilidade informacional nos processos de tomada de decisão e de controle. Essas discussões revelam a importância da contabilidade como mecanismo construtor de informação organizacional. A utilidade da informação contábil é, por muitas vezes, reduzida em função de influências significativas quanto ao seu objetivo, assim como, pelos problemas de agência caracterizados pela assimetria da informação, que tomam maior proporção no âmbito da administração pública. A importância dos profissionais de controle interno do setor público é destacada, nesse contexto, porquanto sua atuação é capaz de propiciar a redução das barreiras à maximização da utilidade da informação contábil. A pesquisa explora essa temática sobre a percepção de profissionais da carreira de controle interno do Governo do Estado de Pernambuco, perseguindo-se o objetivo de caracterizar a percepção desses profissionais sobre as características qualitativas da informação contábil e o nível de importância atribuído a essas características, utilizando-se para isso de um delineamento metodológico experimental e da utilização de um questionário como instrumento de coleta de dados. Os resultados revelam que a presença das características qualitativas da informação contábil impacta as escolhas realizadas por esses profissionais, e que esses possuem nível de percepção satisfatório acerca das características qualitativas e, no geral, julgam estas como muito importantes para a utilidade da informação contábil. Dessa forma, a pesquisa realizada apresenta sua contribuição no que concerne a investigação da percepção das características qualitativas da informação contábil por profissionais de controladoria do setor público.
Bibliotekininko vaidmuo informacinio raštingumo ugdymo kontekste
Authors: Grigas Vincas
Published: June 2021

XXI amžiuje informacinis raštingumas tampa svarbiu gebėjimu. Pasaulio praktika rodo, kad informacinio raštingu­mo ugdymu užsiima dažniausiai akademinių bibliotekų darbuotojai: šis dalykas jų darbotvarkėje tampa vis svarbesnis. Aukštojoje mokykloje ugdymo veikla – akademinio personalo prerogatyva. Todėl bibliotekininkų užmojis užsiimti ug­dymo veikla iškelia probleminį klausimą: ar tokia veikla informacinio raštingumo diegimo kontekste yra pagrįsta, ar ji atitinka bibliotekoms skirtą informacijos paslaugų teikimo užduotį? Taip atsiranda būtinybė nagrinėti bibliotekininkų vykdomos ugdymo veiklos specifiką ir įvertinti, kaip ji siejasi ir kuo skiriasi nuo įprasto bibliotekininkų darbo baro – informacijos paslaugų teikimo. Ugdymo veiklos įgyvendinimas lėmė naują bibliotekininko specializaciją, įvardytą terminu „bibliotekininkas edukatorius“. Šios specializacijos aktualumą padėjo įvertinti darbo skelbimų, publikuotų IFLA duomenų bazėje, analizė. Tyrimas atspindi padėtį pasaulio bibliotekose, rodančią, kad bibliotekininkų edukatorių paklausa darbo rinkoje yra didelė. Atlikta ir Lietuvos valstybinių universitetinių aukštųjų mokyklų bibliotekų darbuotojų apklausa, siekiant įvertinti bibliotekininko edukatoriaus specializacijos aktualumą mūsų šalyje.

Spatiotemporal Variability in the Oxidative Potential of Ambient Fine Particulate Matter in Midwestern United States
Authors: Yu Haoran , Puthussery Joseph Varghese , Wang Yixiang , Verma Vishal
Published: June 2021

Abstract. We assessed the oxidative potential (OP) of both water-soluble and methanol-soluble fractions of ambient fine particulate matter (PM2.5) in the midwestern United States. A large set of PM2.5 samples (N = 241) were collected from five sites, setup in different environments, i.e. urban, rural and roadside, in Illinois, Indiana and Missouri during May 2018–May 2019. Five acellular OP endpoints, including the consumption rate of ascorbic acid and glutathione in a surrogate lung fluid (SLF) (OPAA and OPGSH, respectively), dithiothreitol (DTT) depletion rate (OPDTT), and ·OH generation rate in SLF and DTT (OPOH-SLF and OPOH-DTT, respectively), were measured for all PM2.5 samples. PM2.5 mass concentrations in the Midwest US as obtained from these samples were spatially homogeneously distributed, while most OP endpoints showed significant spatiotemporal heterogeneity. Seasonally, higher activities occurred in summer for most OP endpoints for both water- and methanol-soluble extracts. Spatially, roadside site showed highest activities for most OP endpoints in the water-soluble extracts, while only occasional peaks were observed at urban sites in the methanol-soluble OP. Most OP endpoints showed similar spatiotemporal trends between mass- and volume-normalized activities across different sites and seasons. Comparisons between two solvents (i.e. water and methanol) showed that methanol-soluble OP generally had higher activity levels than corresponding water-soluble OP. Site-to-site comparisons of OP showed stronger correlations for methanol-soluble OP compared to water-soluble OP, indicating a better extraction of water-insoluble redox-active compounds from various emission sources into methanol. We found a weak correlation and inconsistent slope values between PM2.5 mass and most OP endpoints. Moreover, the poor-to-moderate intercorrelations among different OP endpoints infer different mechanisms of OP represented by these endpoints, and thus demonstrate the rationale for analyzing multiple acellular endpoints for a better and comprehensive assessment of OP.
Implementation of aerosol data assimilation in WRFDA (V4.0.3) for WRF-Chem (V3.9.1) using the MADE/VBS scheme
Authors: Ha Soyoung
Published: June 2021

Abstract. The Weather Research and Forecasting model data assimilation (WRFDA) system, initially designed for meteorological data assimilation, is extended for aerosol data assimilation for the WRF model coupled with Chemistry (WRF-Chem). An interface between WRF-Chem and WRFDA is built for the Regional Atmospheric Chemistry Mechanism (RACM) chemistry and the Modal Aerosol Dynamics Model for Europe (MADE) coupled with the Volatility Basis Set (VBS) aerosol schemes. This article describes the implementation of the new interface for assimilating PM2.5, PM10, and four gas species (SO2, NO2, O3, and co) on the ground. And the effects of aerosol data assimilation are briefly examined through a month-long case study during the Korea-United States Air Quality (KORUS-AQ) period. It is demonstrated that the 3DVAR analysis can lead to consistent forecast improvements up to 26 %, diminishing most systematic bias errors for 24 h.
