Abstract. Zulaika E, Utomo MAP, Alami NH, Kuswytasari ND, Shovitri M, Bayuaji R, Prasetyo EN. 2019. Short communication: The diversity of ureolytic bacteria isolated from limestone in East Java, Indonesia based on amino acid sequences encoded by ureC. Biodiversitas 20: 2316-2320. Ureolytic bacteria isolated from limestone are capable to produce urease enzyme which can breaks down urea into carbonate (CO32), has been utilized for various building material bioremediation and restoration. In this present study, we figured out the diversity and genetic relationship of α sub-unit ureC gene among six ureolytic bacteria (JA1, JB2, JB3, JA4, AK4, and SU1) which were isolated from limestone area in East Java province. PCR was conducted to detect the gene which encoded active site of urease, ureC. Followed by sequences translation using BLAST-X (Basic Local Alignment Search Tool) based on the name and function of formed proteins and then aligned to the conserved domain database. Furthermore, the functions and characters of formed proteins were described. Based on PCR results, all isolates showed 340 bp DNA band which indicate the presence of ureC gene. The results of BLAST-X, JB2 isolates showed 100% similarity with the α sub-unit ureC gene from Lysinibacillus sphaericus B1-CDA (WP_054549252.1). Whereas, JA1 isolates showed 88% similarity (lowest) with the α sub-unit ureC gene from Bacillus cihuensis FJAT-14515 (WP_028391929.1). The present study reveals that ureC phylogeny can be used in order to investigate ureolytic bacteria species which isolated from calcareous area in East Java province.

Abstract. Sulistyawati, Roeswitawati D, Ibrahim JT, Maftuchah. 2019. Genetic diversity of local sorghum (Sorghum bicolor) genotypes of East Java, Indonesia for agro-morphological and physiological traits. Biodiversitas 20: 2503-2510. Sorghum (Sorghum bicolor (L.) Moench) has great potential to be cultivated because it has extensive adaptability, tolerant to drought and puddles, can produce on marginal land and relatively resistant to pests and diseases. To meet the food requirement, sorghum can be grown in Indonesia as an alternative food source other than rice. This study aims to obtain information on the agro-morphological and physiological characters of nine local sorghum genotypes in East Java, Indonesia so that they can be used as parents in improving the nature of varieties. The experiment was conducted in a Randomized Block Design, using nine local sorghum genotypes from East Java in three replications. The nine local sorghum genotypes are Sb.Pas, Sb.Lmg 1, Sb.Lmg 2, Sb.Tbn, Sb.Spg 1, Sb.Spg 2, Sb.Tag 1, Sb.Tag 2 and Sb.Jbg. The result showed that nine genotypes that are characterized have a variety of morphological (quantitative and qualitative), agronomic and physiological characters. According to the whole characters observed, there are five genotypes that are recommended for breeding programs, namely Sb.Lmg 1, Sb.Tbn, Sb.Spg 2, Sb.Tag1 and sb.Tag2. This can be proved by the morphological character, genotype Sb.Lmg 1, Sb.Tbn, Sb.Spg 2, Sb.Tag 1 and Sb.Tag2 have a high value of Agronomy character, genotype Sb.Tbn, Sb.Tag 1 and Sb.Tag 2 noted highest production acres-1 harvest age of genjah and medium; the Physiology character, high protein and carbohydrate substances reached by the Sb.Lmg 1 genotype, Sb.Tbn and Sb.Spg 2.
Characterization of physiological states of the suspended marine
microalgae using polarized light scattering
Authors: Wang Yong , Dai Jincai , Liao Ran , Zhou Jin , Meng Fanqiang , Yao Yue , Chen Huirong , Tao Yi , Ma Hui
Published: January 2020

Physiological states of marine microalgal cells can influence
photosynthesis efficiency, which affects approximately half of global
carbon fixation. The detection of the algae physiological profiles is
important for marine ecology and economy. In this paper, we propose a
polarized light-scattering method to detect sensitive changes in the
physiological states of the suspended marine microalgal cells. Our
experimental setup is designed to measure the scattered polarization
parameters of the cells suspended individually in the seawater. Two
species of microalgal cells cultured in the laboratory were measured
for several days. Experimental results showed that both species
display distinctive changes in their polarized photon scattering
features corresponding to changes in their physiological states. The
changes are far more prominent than those displayed in unpolarized
light scattering. Microscopy observations, simulations for
microspheres of different diameters and refractive indices, or
different shapes, indicated that the polarization features of the
scattered photons are sensitive to the submicrometer microstructures
of the cells. This study demonstrates the potential of the polarized
light-scattering technique to characterize the physiological states of
suspended marine microalgae.
Independently tunable Fano resonances in a metal-insulator-metal coupled cavities system
Authors: Chen Yonghao , Chen Li , Wen Kunhua , Hu Yihua , Lin Weitao
Published: January 2020

Herein, multiple Fano resonances with excellent ability to be tuned independently are produced in a sub-wavelength metal-insulator-metal system. The input and output waveguides are separated by a metal gap, and a stub and an end-coupled cavity are placed below and to the right side of the input waveguide, respectively, as discrete states. Owing to the mode interferences, double ultra-sharp and asymmetric Fano resonant peaks are observed in the transmission spectrum. Successfully, the basic structure is extended by two extra rectangular cavities, giving rise to four Fano resonances with high refractive index sensitivity and figure of merit. Due to the discrete modes of Fano resonances from different coupling cavities, their resonant wavelengths can be controlled independently, which can provide greater flexibility for tuning Fano resonances. The performances of the proposed structure are investigated by both the finite-difference time-domain method and the multimode interference coupled-mode theory. It is believed that the research can provide important guidance in designing Fano resonance structures, and the proposed structure has a wide application in sensors, switches, and nano-photonic integrated circuit devices.
Predicted response of an atom to a short burst of electro-magnetic radiation
Authors: Semak V. V. , Shneider M. N.
Published: January 2020

In this work, we present a hypothesis that spectral response of atoms or molecules to a pulse of electro-magnetic radiation with fast rising or falling fronts would contain a unique emission line that is located approximately near the frequency of the natural oscillations of optical electrons. The emission of this “pinging” spectral line would exist during the time that is determined by the time of radiative energy loss by the optical electron. The amplitude of the “pinging” spectral line would be higher for the pulses with faster rising or falling fronts. The simulations using our previously developed model confirmed existence of the “pinging” spectral response. If experimentally confirmed, this work could lead to a new high sensitivity, high signal to noise ratio stand-off detection techniques, and to other yet unknown applications.

Interpretantes dinâmicos de estudantes das relações dos animais humanos e não humanos: uma leitura Peirceana a partir de uma intervenção didática
Authors: Rodrigues Adriana Ribeiro Ferreira , Laburú Carlos Eduardo , Silva Osmar Henrique Moura
Published: January 2020

O presente trabalho apresenta perspectivas de estudantes quanto às formas de relação dos seres humanos com os animais, no contexto da disciplina de Biologia no segundo ano do ensino médio. Por meio de uma intervenção didática que abordou os conteúdos de animais vertebrados segundo um enfoque relacional e de discussão de tais formas de relação, foram produzidas informações baseadas em uma leitura da tríade dos interpretantes dinâmicos de Peirce gerados pelos estudantes. Dentro desse referencial semiótico, observou-se ser possível discriminar os interpretantes emocional, energético e Lógico e que os mesmos se estruturaram distintamente do interpretante dinâmico inicial possuído pelos aprendizes após intervenção didática. De fato, o trabalho mostra a qualidade alterada dos interpretantes, desejada em razão de um processo de debate e aprendizagem acerca do tema.

Published: January 2020

O presente artigo tem como objetivo refletir sobre o que queremos com a Oceanografia Socioambiental. A ideia não é dar uma resposta pronta, mas buscar iniciar uma reflexão que possa culminar, no futuro, em uma construção coletiva. Para tanto, entendemos como necessário refletir sobre o papel da ciência na conformação da realidade do mundo atual. E, nesse sentido, refletir sobre a Oceanografia enquanto ciência e a necessidade de pensar a sua decolonização para caminhar no sentido pós-abissal orientado desde o sul global. Para isso, entendemos que os conceitos de conflito ambiental, justiça ambiental e educação ambiental para a justiça ambiental podem servir como princípios suleadores para este campo.

Time of signing in the Estonian digital signature scheme
Authors: Mets Tõnu , Parsovs Arnis
Published: January 2020

There is a widespread misconception among some lawyers, technologists and the public that the Estonian digital signature scheme provides reliable proof of the time when a document was digitally signed. In this article Tõnu Mets and Arnis Parsovs show that the legal requirement to establish the time of signing is not met in practice. The related legal requirement that the validation of the digital signature should confirm that the certificate was valid at the time of signing is also not met. The authors analyse the legal consequences of this, and discuss possible solutions for the issues that arise. They note that digital signature schemes used in other countries implementing Regulation (EU) No 910/2014 of the European Parliament and the Council of 23 July 2014 (eIDAS) are likely to share the problems discussed in this article.

Authors: Kusumaningtyas Eni , Subekti Didik Tulus , Fitaningtyas D FL
Published: January 2020

Mare milk protein contains bioactive peptide which beneficial for human and animal health. Peptides in the fraction and single may show different activities.  The objectives of the study were to evaluate antimicrobial and anti-inflammation activities of the fraction and single peptide derived from mare milk protein. Antimicrobial assay was conducted by testing antibacterial and antifungal activities of fraction <3 kDa, peptide HPYFYAPELLYYANK, LVNELTEFAK and LANSLTEFAK against Escherichia coli and Candida albicans. Anti-inflammation effect was detected by interleukin 1-β (IL- 1β) and Tumor Necrosis Factor -α (TNF-α) production in mice after administration of Escherichia coli’s lipopolysaccharide (LPS) and combined with fraction or single peptide. The result showed that antibacterial and antifungal of fraction <3 kDa was higher than all of single peptide. This may because of synergistic interaction among peptide in the fraction which increase the activities. Fraction <3 kDa was also able to decrease production of IL-1β and TNF-α better than single peptide indicated its ability to decrease inflammation. Based on the results, antimicrobial and anti-inflammation activities fraction <3 kDa was better than single peptide.

Published: January 2020

Matrix 2 ectodomain (M2e) protein is a potential antigen for detection of influenza A virus infection in vaccinated poultry (DIVA test). However the M2e antigenicity and immune response it induces in either humans or animals are poorly understood. Seventeen M2e peptides and sixteen recombinant M2e (rM2e) proteins with amino acid (aa) changes introduced at position 10, 11, 12, 13 14, 16, 18 and 20 were compared by western blot (WB) and enzyme-linked immunosorbent assay (ELISA) using mouse anti-M2 monoclonal antibody (mAb) 14C2, and anti-M2e peptide chicken and rabbit polyclonal antibody (pAb). The mAb 14C had the best discriminating power and indicated that all six positions contributed to the M2e antigenicity. Position 11 was the important immunodominant and affected Mab14C binding to a greatest degree. Changes in the adjacent position 14, 16 and 18 also influenced the binding, and it detected regardless of the method (WB or ELISA), or the antigen used (M2e peptide or rM2e). For chicken pAb and rabbit pAb, the immunodominant aa was position 10 and the antibody reaction was not affected by aa change at 11. The binding of rabbit pAb was also affected by changes at 14 and 16, which confirm the contribution of these positions to the M2e antigenicity. Position 10 was the only important position for the binding of chicken pAb to M2e. Overall, the study showed that the M2e antigenic sites are located between residues 10 – 18 and that aa changes at position 10, 11, 12, 14, 16 and 18 may all affect the antibody binding within the M2e protein.

Published: January 2020

The aim of this study was to determine the effect of adding Insulin Transferrin Selenium (ITS) in the medium on maturation and fertilization rates of Bali cattle oocytes. The ovarium of Bali cows were sliced to produce oocytes, then the collected oocytes were subsequently selected based on their quality. Those oocytes were maturated for 24 hours and then fertilized for 18 hours in the incubators of 5% CO2 with temperature of 38.5ºC. Oocytes were stained using 2% of aceto orcein, and observed under a microscope. This study was divided into four treatments at different addition of ITS in the medium and replicated four times, and analized using a Factorial Complete Randomized Design (CRD)at each treatment. The treatments consisted of P0 as control, P1 (5 ng/ml), P2 (10 ng/ml), and P3 (15 ng/ml). Parameters observed in this study were the stages of oocytes maturation rate that consisted of germinal vesicle (GV), germinal vesicle break down (GVBD), metaphase I (M-I), and metaphase II (M-II), and fertilization rate that consisted of absence of pronucleus (P0), 1 pronucleus (PN1), 2 pronucleus (PN2), and more than two pronucleus (>2PN). The results of this study showed that addition of ITS at 5-15 ng/ml did not effect maturation and fertilization rates of Bali cows oocytes.The conculision of the study is addition of ITS at 5 ng / ml produces the best level of maturation and for the best level of fertilization with addition ITS at 15 ng / ml.

Construction Services Law is a statutory regulation that is used to regulate all matters involving construction services, whereas in this study conducted in Jakarta, Indonesia, Law No. 18 of 1999 about Construction Services and Law No. 2 of 2017 about Construction Services. With changes in the Construction Services Law, there are differences in the form of revisions, additions, and reductions. These differences and changes are analyzed with the aim of developing a better Construction Services Law in the future. The method used in this research is a literature study method and questionnaire survey method. Questionnaire questions were formed based on literature studies from previous research and Construction Services Law discussed in this study. Data obtained from respondents were entered into the IBM SPSS Statistics 23 program and then conducted a validity test, reliability test, correlation test, and regression analysis. The analysis shows that there are several Construction Services Law’s regulations which cannot be a good guide for construction service providers and users yet, due to: the provisions regarding building failures are not well explained, the general lack of provisions governing the selection of expert assessors, the lack of clarity governing labor standards construction work and unclear regulations regarding sanctions for parties involved in construction work.

Maintenance of good and sustainable irrigation ponds have an impact on ensuring the sustainability of the irrigation system. For this reason, it is necessary to develop a reservoir maintenance model based on multicriteria analysis relating to the type of maintenance. The method used Structural Equation Model (SEM) with the WarpPLS approach. The criteria used Structural Stability, Economy / Finance, and Physical & Environmental. The findings obtained variable structural stability has a very significant effect on the maintenance of irrigation ponds (r <0.01 and β = 0.73). Economic / financial variables have not significant effect on reservoir maintenance where r = 0.3 and β = 0.03. Physical and environmental variables also did not directly influence the maintenance of ponds with r = 0.29 and β = 0.03. However, the physical & environmental variables significantly influenced structural stability with r <0.01 and β = 0.32. Physical and environmental variables also significantly influenced economic/financial where r <0.01, and β = 0.45. This finding supported various previous studies for structural stability variable but different for economic/financial variables that did not significantly affect by the determination of reservoir types.

This final 2019 issue of Studies in Second Language Learning and Teaching brings together six original empirical studies and two book reviews. In the first paper, Marco Octavio Cancino Avila reports the results of a study that investigated the learning opportunities arising in classroom interactions, placing special emphasis on the contribution of teachers’ and learners’ overlapped turns. Using conversational analysis, he analyzed extracts from six classes taught by three teachers to adult learners of English as a foreign language in Chile. He found that teachers’ skill in appropriately handling learners’ turns that overlapped or directly followed their own had a positive impact on participation and language learning as long as learners were given adequate interactional space (Sert, 2015). The second contribution by Reza Shirani also focuses upon classroom interaction, with the caveat that the main concern is with the effectiveness of different types of corrective feedback (CF). The study explored the relationship between the level of explicitness of input-providing (i.e., recasts) and output-promoting (i.e., prompts) CF moves, and the occurrence of uptake and repair in a foreign language context in Iran. Using the model of error treatment proposed by Lyster and Ranta (1997) to analyze transcripts of 36 hours of classroom interactions in three intact classes, the researcher found that prompts tended to be used more frequently than recasts, which stands in contrast to previous findings, but at the same time produced evidence that greater salience of CF is a crucial factor for the occurrence of self-correction, which is in line with prior research.
The impact of studying abroad on students’ intercultural competence: An interview study
Authors: Sobkowiak Paweł
Published: January 2020

This paper presents qualitative research examining to what extent sojourns abroad engage their participants in intercultural interactions and whether or not such experience translates into students’ intercultural growth. The results of the study demonstrated that studying abroad did not provide students with ample opportunities to immerse into the local community and fully discover a new cultural environment. However, students surrounded by local and their fellow international students met foreign cultures, which motivated them to explore and interpret the encountered diversity, and thus equipped them with knowledge about foreign cultures, sensitizing them to cultural diversity. Sometimes such contacts challenged students’ preconceived judgments and stereotypes of specific cultural groups, their ways of thinking, valuing and acting, and resulted, to a lesser or greater extent, in rethinking these, leading to changing attitudes and values. International experiences also stimulated students to self-analyze their own cultural identity, and thereby contributed to their growth in self-awareness in this respect. By offering opportunities for experiencing cultural differences and prompting students to develop coping strategies and to make references to the home culture, the sojourn is thus of significant importance for tertiary students, allowing for fostering their intercultural development to a certain degree.
Hacia un cribado personalizado del cáncer de próstata
Authors: Filella Xavier
Published: January 2020

La utilidad del antígeno específico de la próstata (PSA) en el cribado del cáncer de próstata (CaP) es una cuestión controvertida. Los resultados publicados son polémicos en cuanto a la consecución de una disminución de la mortalidad y al rigor metodológico. No obstante, hay coincidencia en observar la relación del cribado con un aumento del número de CaP indolentes.

La controversia no se limita a la incertidumbre que rodea la utilidad del cribado, sino también al intervalo de edad en que podría ser aplicado, la definición de grupos de riesgo según un PSA basal, el intervalo de las mediciones de PSA o la inclusión de otros biomarcadores (PHI, 4Kscore). Actualmente, la mayoría de las sociedades no aconseja la práctica generalizada del cribado, pero sí lo admiten tras un dialogo informativo con el paciente, evaluando beneficios y riesgos.

En esta reflexión deben valorarse tanto los riesgos de hacer el cribado (falta de especificidad del PSA, sobrediagnostico) como los riesgos asociados a no hacer el cribado (aumento de pacientes que debutan con metástasis). Recientemente, diversos autores abogan por un cribado personalizado que podría cambiar el balance entre beneficios y riesgos y hacer oportuna, en función del riesgo de cada individuo, su implementación.
Transcendental Idealism and Naturalism: The Case of Fichte
Authors: Phillips Rory Lawrence
Published: January 2020

In this paper, I explore the relationship between naturalism and transcendental idealism in Fichte. I conclude that Fichte is a near-naturalist, akin to Baker, Lynne Rudder (2017). “Naturalism and the idea of nature,” Philosophy 92 (3): 333–349. A near-naturalist is one whose position looks akin to the naturalist in some ways but the near-naturalist can radically differ in metaphilosophical orientation and substantial commitment. This paper is composed of three sections. In the first, I outline briefly what I take transcendental idealism to be, as well as some differences in types of naturalism, and how this maps on to Fichte. In the second, I give an exegesis of Fichte’s key arguments in the Later Jena period, which are important for the question of his relationship to naturalism. In the third, I continue the exegesis with a discussion of Fichte’s conception of God, and conclude that these arguments support a near-naturalist reading of Fichte.

Sepsis, or blood poisoning, is a savage response of the body to infection. It can lead to organ failure, blood pressure decline, heart failure, and coma. Between 20 and 30 million people suffer from sepsis each year, leading to 8 million deaths. Although certain people are more at risk than others (young children, elderly), anyone can develop sepsis. Patients are resuscitated and treated with antibiotics, and their organ functions are supported. Despite the investment in sepsis research during the previous decades, successful clinical trials are scarce and sepsis remains one of the most difficult and deadly unmet medical needs of today. A study in this issue now provides new insight into sepsis and points to a therapeutic future [1].

Excessive fat accumulation causes obesity and many diseases. Previous study demonstrates VEGFB universal knockout induces obese phenotypes including expansion of white adipose tissue, whitening of brown adipose tissue, increase of fat accumulation and reduction in energy consumption. However, roles of VEGFB in adipose tissues are not clear. In this study, we have generated a mouse model with adipose-specific VEGFB repression using CRISPR/dCas9 system (Vegfb
AdipoDown
) and investigated the roles of VEGFB in adipose development and energy metabolism. VEGFB repression induced significant changes in adipose tissue structure and function. Vegfb
AdipoDown
mice have larger body sizes, larger volume of white adipose tissues than its wild type littermates. Adipose-specific VEGFB repression induced morphological and functional transformation of adipose tissues toward white adipose for energy storage. Metabolic processes are broadly changed in Vegfb
AdipoDown
adipose tissues including carbohydrate metabolism, lipid metabolism, nucleotide metabolism and amino acid metabolism. We have demonstrated that adipose VEGFB repression can recapitulate most of the phenotypes of the whole body VEGFB knockout mouse. Intriguingly, approximately 50% VEGFB repression in adipose tissues can almost completely mimic the effects of universal Vegfb deletion, suggesting adipose VEGFB is a major regulator of energy metabolism and may be important in prevention and treatment of obesity.

In eukaryotic cells, the spatial organization of genes within the nucleus is correlated with their expression. However, correlation is not causa-tion. To determine how nuclear spatial organization affects gene expression, Di Stefano et al. studied...

The three-dimensional (3D) organization of chromosomes can influence transcription. However, the frequency and magnitude of these effects remain debated. To determine how changes in chromosome positioning affect transcription across thousands of genes with minimal perturbation, we characterized nuclear organization and global gene expression in budding yeast containing chromosome fusions. We used computational modeling and single-cell imaging to determine chromosome positions, and integrated these data with genome-wide transcriptional profiles from RNA sequencing. We find that chromosome fusions dramatically alter 3D nuclear organization without leading to strong genome-wide changes in transcription. However, we observe a mild but significant and reproducible increase in the expression of genes displaced away from the periphery. The increase in transcription is inversely proportional to the propensity of a given locus to be at the nuclear periphery; for example, a 10% decrease in the propensity of a gene to reside at the nuclear envelope is accompanied by a 10% increase in gene expression. Modeling suggests that this is due to both deletion of telomeres and to displacement of genes relative to the nuclear periphery. These data suggest that basal transcriptional activity is sensitive to radial changes in gene position, and provide insight into the functional relevance of budding yeast chromosome-level 3D organization in gene expression.
Costa Rica y el Brexit
Authors: Rojas Noskova Kira
Published: January 2020

El objetivo del artículo es generar una reflexión sobre los efectos de la ya materializada salida de Reino Unido de la Unión Europea (UE) en las relaciones comerciales de Costa Rica. El abordaje del fenómeno se realiza desde la perspectiva de las teorías de la interdependencia compleja y del realismo periférico. A su vez, brinda una mirada a las derivaciones sociales de esta decisión, cuyas consecuencias pueden ser estudiadas desde múltiples aristas. Metodológicamente, se emplea la técnica de revisión bibliográfica de fuentes primarias y secundarias. Entre los hallazgos encontrados, se obtiene que el comercio entre Costa Rica y Reino Unido mantiene la balanza comercial a favor del primero y que se deben redoblar esfuerzos para mejorar la oferta exportable con productos de mayor valor agregado. En el ámbito económico, se concluye que el Brexit no amenaza la estabilidad de la economía costarricense, sino que ofrece oportunidades para fortalecer las relaciones entre ambos países a través de los instrumentos comerciales disponiblesy de la cooperación. En el ámbito social, es un fenómeno del cual se deben aprender lecciones importantes para el desarrollo de políticas conjuntas, con el fin de mejorar los procesos de integración.
Ancient Catalogues of Memory Institutions in Manuscript Collections of the Wróblewski Library of Lithuanian Academy of Sciences: the Inventory of the Slutsk St. Elias Monastery
Authors: Cicėnienė Rima
Published: January 2020

Ancient book lists and catalogues are one of the most important sources of cultural and scientific history. Books listed in the documents allow us to research the history of not only various institutions and their libraries, but also the history of literature and science, the totality of writing functioned in the country at the time, as well as human and institutional cultural connections. This article has two objectives: firstly – to briefly discuss the old book lists and catalogues stored in the manuscript collections of the Wroblewski Library of Lithuanian Academy of Sciences (hereinafter – WLLAS); secondly – to publish the inventory of the Slutsk St. Elias Monastery in 1575. Manuscripts in the WLLAS funds were analyzed in order to attain these purposes. The article approach reasons to compile catalogues, information capture techniques and their changes using particular documents from Library funds. The conclusion of this publication reveals that if all in the library remaining ancient book lists/catalogues and the information contained in them were studied and systematized, a new and sizable artifact complex for the scientists would form. This would allow the continuation of already commencing works and the broadening of aspects in the studies of the library history and the ancient books collections’ composition along with changes in it. This is particularly important for studying the functioning of books or library history in their earliest periods in GDL. This paper presents the publication of the inventory from Slutsk St. Elias Monastery in 1575. This document illustrates the way books were listed at that time, providing additional knowledge about the earliest known institutional collections of books in GDL. A large St. Elijah‘s Monastery’s book collection of the relevant time period, also included in this article, strengthens the argument, that Slutsk was one of the biggest Lithuanian Grand Duchy’s written language centers in the 16th century. Extensive amount of information on historical icons, liturgical objects, variety of textiles used in the time period might appeal to anthropologists, interested in ecclesiastical art, historians of Orthodox Church researching the evolution of rites, liturgical utensils used and church architecture, finally, linguists, examining the Ruthenian language and terminology of the time.
The Minutes of the Meetings of the Commission of Archaeology in Vilnius: 1856–1858
Authors: Būčys Žygintas
Published: January 2020

The Museum of Antiquities and Interim Commission of Archaeology in Vilnius which was the most significant educative scientific and cultural centre of that time both in Vilnius and Lithuania was founded in 1855 and was active for nearly a decade. The members of the Commission initiated and organized the research of the region in the fields of archaeology, history, and natural sciences. The Commission engaged an active part of the educated Lithuanian society in collecting the heritage of local history. Historical sources and scientific studies were also published by the Commission. The meetings of the Commission were held once a month, where past activities, current issues, and future plans were discussed as well as scientific reports were presented to the attendance. Extraordinary meetings were organized for the exceptional occasions, too. The minutes of the meetings of the Interim Commission of Archaeology in Vilnius are the source, which reflects comprehensively the activity of this public organization and its diverse character. The minutes also reflect the relationship between the Commission and the Tsarist administration: the flexibility in seeking suitable conditions for its activity, and the usage of the so-called Aesopian language in actualizing the history and the heritage of the Grand Duchy of Lithuania. The minutes reflect amply the scientific, cultural, and intellectual life of the then Lithuania. The publication presents the translated minutes of the meetings of the Interim Commission of Archaeology in Vilnius of the first three years of its activity.
Systematic Risk and Accounting Determinants: An Empirical Assessment in the Indian Stock Market
Authors: Parthasarathy Srikanth
Published: January 2020

This study explores the contemporaneous association between market determined risk measures and accounting determined risk measures using the large liquid non-financial stocks in the Indian stock market in the recent 2012-2017 period. Two measures of systematic risk and seven accounting determined risk measures are chosen based on prior research. This study uses three regression techniques, namely Ordinary Least Squares (OLS), stepwise regression and robust regression, to identify the influential accounting variables for the systematic risk measured by market beta. The results evidence that there is a high degree of contemporaneous association between market determined and accounting determined risk measures, with nearly 30% of the cross sectional variance in systematic risk explained by accounting determined risk measures. The results suggest that the accounting variables can be used in the predictive models of future risk, leading to superior decision making at the level of individual decision maker.
