Trabajo a distancia y conciliación familiar y laboral
Authors: Cordero Gordillo Vanessa
Published: July 2021

La pandemia causada por el virus SARS-CoV-2 ha dado lugar a un incremento exponencial del número de personas trabajadoras que prestan servicios a distancia, especialmente a través del teletrabajo, lo que ha motivado la aprobación del RD-Ley 28/2020 a fin de dotar a esta forma de trabajo de un régimen jurídico más apropiado que el anterior art. 13 ET. Asimismo, el trabajo a distancia ha jugado un importante papel en la conciliación de la vida familiar y laboral durante la pandemia. De hecho, entre sus ventajas es frecuente mencionar el hecho de que facilita la compatibilización de las responsabilidades familiares y las profesionales, aunque también presenta algunos riesgos desde esta perspectiva. Partiendo de estas premisas, este trabajo aborda el trabajo a distancia y su relación con la conciliación de la vida familiar y laboral desde una doble perspectiva: como herramienta de conciliación, tanto por la vía del art. 34.8 ET como en el contexto de la pandemia, planteando si el RD-Ley 28/2020 debe considerarse aplicable en estos supuestos, y respecto a los derechos de conciliación de las personas trabajadoras a distancia en virtud de esta última norma.

Optimization of Modified Murashige and Skoog (MS) Medium Promoting Efficient Callus Induction in Zinnia elegans
Authors: Samantaray Utkalendu Suvendusekhar , Singh Tanima
Published: July 2021

Zinnia (Zinnia elegans Jacq.) occupies a pristine place in the garden for its bright colours and long flowering period. Zinnias are propagated by seeds hence genetic variation and a tendency for stock plants to decline in vigor over time is high. Young internodal explants of this species were grown on modified Murashige and Skoog (MS) medium supplemented with various growth hormones to evaluate callus induction. 2,4 dichlorophenoxyacetic acid (2,4-D) at 1.0 mg/L was shown to be the best choice for a high percentage of callus induction (70-73%) and a rapid growth rate of viable and healthy callus. A large-scale and quick callus generation protocol was developed in the lab and might be used for in-vitro micropropagation.

Vestidas en la historia: una mirada a la colección de Indumentaria femenina del Museo Histórico Nacional (Buenos Aires, Argentina)
Authors: Ullua Juliana , Van Peteghem Inés
Published: July 2021

Distintas mujeres de la primera mitad del siglo XIX, en su mayoría pertenecientes a la elite porteña, vistieron sobre sus cuerpos diversas prendas, como vestidos, capas, batas, mantillas, que décadas más tarde fueron donadas a uno de los principales museos históricos de Argentina, el Museo Histórico Nacional. En este artículo pretendemos estudiar esas prendas como objetos que reflejan no solo las vidas cotidianas de la época, en las que fueron usadas, sino también cómo esos objetos se convirtieron en piezas dignas de ser testimonio de la historia nacional.

Otro de nuestros objetivos con este artículo es generar nuevos conocimientos sobre las mujeres del pasado, que logren enriquecer los guiones museológicos actuales. Además, buscamos sumar un tipo de fuente material al estudio de la indumentaria que permita hacer un aporte distinto sobre la circulación de estas prendas, como así también indagar sobre dimensiones simbólicas y políticas que se desprenden de su uso.
Vestidos de papel: representaciones de la moda en la prensa de Buenos Aires, décadas de 1860 y 1870
Authors: Garabana Teresita
Published: July 2021

El artículo analiza representaciones de la moda en un conjunto de periódicos publicados en Buenos Aires en las décadas de 1860 y 1870. Tras describir los rasgos principales de la prensa desarrollada en este período, el trabajo analiza las ilustraciones de moda –figurines– que circulaban en algunos periódicos, y los textos que convivían con dichas imágenes. El artículo explora las ambigüedades y tensiones entre textos e imágenes. Así, se argumenta que la moda ocupó un lugar renovado dentro de la prensa: los figurines no solo transmitían las modas parisinas en Buenos Aires, sino que comunicaban un estilo de vida asociado a lo burgués-femenino, mientras que los textos que los describían buscaban adaptarlos a la realidad local. Asimismo, en las crónicas de la moda, otras voces advertían acerca de los peligros que la moda y el consumo de vestimenta podría traer para las mujeres y sus familias.
De los márgenes al centro. Ofertas terapéuticas y charlatanismo durante la epidemia de fiebre amarilla en el Buenos Aires de 1871
Authors: Guiastrennec Lucas
Published: July 2021

Médicos, religiosos y policías han sido objetos de estudios para adentrarse en las experiencias acaecidas en los fatídicos meses que presenció Buenos Aires durante la epidemia de fiebre amarilla de 1871. Sin embargo, la oferta de productos y prácticas terapéuticas que operaron desde los márgenes de la biomedicina continúa aún pendiente de exploración. El presente artículo tiene como objetivos, por un lado, analizar las publicidades de medicamentos y preservativos de venta libre en la prensa porteña que se complementó con las indicaciones recetadas por la medicina diplomada. Por otro lado, examinar dos casos de charlatanería con el fin de iluminar la compleja trama sanitaria y política a partir de actores sociales marginados tanto por la biomedicina del momento, como por la historiografía actual.

Lampiran 5A paper Removal of nitrate, ammonia and phosphate from aqueous solutions in packed bed filterusing biochar augmented sand media
Authors: de Rozari Philiphi
Published: July 2021

Nutrients from wastewater are a major source of pollution because they can cause significant impact on the ecosystem. Accordingly, it is important that the nutrient concentrations are kept to admissible levels to the receiving environment. Often regulatory limits are set on the maximum allowable concentrations in the effluent. Therefore, wastewater must be treated to meet safe levels of discharge. In this study, laboratory investigation of the efficiency of packed bed filters to remove nitrate, ammonium and phosphate from aqueous solutions were conducted. Sand and sand augmented with hydrochloric acid treated biochar (SBC) were used as packing media. Synthetic wastewater solution was prepared with PO43-, NO3-, NH4+ concentrations 20, 10, 50 mg/L, respectively. Each experiment ran for a period of five days; samples from the effluent were collected on alternate days. All experiments were duplicated. Over the experiment period, the average removal efficiency of PO43-, NO3-, NH4+ were 99.2%, 72.9%, 96.7% in the sand packed columns and 99.2%, 82.3%, 97.4% in the SBC packed columns, respectively. Although, the presence of biochar in the packing media had little effect on phosphate and ammonium removal, it significantly improved nitrate removal
Lampiran 1F Paper Single production of Kojic acid by Aspergillus flavus and the revision of flufuran
Authors: de Rozari Philiphi
Published: July 2021

Timor Island is very hot and dry due to the high intensity of sunlight experienced throughout the year. The endophytic fungi Aspergillus flavus had been isolated from medicinal plants such as Catharanthus roseus, Annona squamosa and Curcuma xanthorisa. The endophytic fungi A. flavus from each plant was cultivated on solid rice media and then analyzed for its capability for producing kojic acid. The production of kojic acid was analyzed by HPLC; the highest amount of kojic acid was observed from the endophytic fungi A. flavus, isolated from the stem of Catharanthus roseus, followed by A. flavus from Annona squamosa and Curcuma xanthorisa. Simple VLC fractionation of the extract of A. flavus from C.roseus led to the isolation of around 11.1 g of pure kojic acid. The structure of kojic acid (1) was confirmed by NMR and MS spectroscopic data. A comparison of the NMR data with the literature supported the revision of the natural product flufuran to kojic acid. To the best of our knowledge, this is the first report of a strain of endophytic fungi producing only kojic acid without any other toxic metabolites such as alfatoxins. Therefore, this Aspergillus flavus strain can be applied as a potential producer of kojic acid for industrial use.
Comment on “The COVID-19 infodemic does not affect vaccine acceptance”
Authors: Gallotti Riccardo , Sacco Pier Luigi , De Domenico Manlio
Published: July 2021

In a recent paper by Valensise et al [1], the authors present an analysis of social media data – from Facebook and Twitter – and vaccine hesitancy data – from Facebook – to provide evidence that the overabundance of potentially unreliable information, known as infodemic, does not affect vaccine acceptance. If confirmed, this result could have a dramatic impact on public health policies across the world, suggesting that current actions taken in place to contain and prevent the spreading of disinformation and misinformation might be useless to significantly hinder vaccine hesitancy. We disagree with this conclusion on the basis of existing literature that the authors fail to consider,of methodological concerns that suggest that their approach might have crucial flaws, and of an alternative empirical analysis unraveling a broader and richer picture to interpret.Simplistic analyses are not enough to assess the complex interplay between two complex social and behavioral phenomena such as vaccine hesitancy and infodemic: more sophisticated analyses are needed to account for the different intervening socio-cultural, behavioral, environmental and epidemiological factors. Under these conditions, we conclude that the authors’ main claim is conceptually and empirically unsupported. We are sincerely concerned that, if measures disregarding the circulating disinformation around the COVID19 vaccines were endorsed by policy makers in the design of future public health policies, it might lead to serious negative consequences by dangerously overlooking a major potential driver of dysfunctional behavioral responses to public health policies and goals.

This research aims to; (1) to determine the water quality of Liliba River and to analyse the water quality index of Kali Liliba River using STORET (2) to identify the perceptions of various stakeholders in Kali Liliba to achieve sustainable use of water resources The study was conducted by measuring several water quality parameters such as turbidity, temperature, TDS, turbidity, smell, taste, pH, DO, ammonium, N-Nitrite, phosphate, oils and fats, hardness (CaCO3) in several sampling points and distributing questionnaires to communities living in Kali Liliba River Basin. The results showed that ammonium and phosphate concentrations in Kali Liliba had exceeded the threshold specified in accordance with Government Regulation No.82 of 2001. In addition, water quality status using STORET INDEX analysis showed that sub DAS Kali Liliba was categorized medium contaminated. The waste disposal from septic or greywater, disposal of tofu industry waste, and pig farm waste was the major contribution of water pollution in Kali Liliba.
Annual Normalized Difference Vegetation Index time-series data for Australian statistical areas
Authors: Ramsey Simon , Mavoa Suzanne
Published: July 2021

Google Earth Engine provides researchers with a platform for conducting planetary scale analysis of environmental processes and landcover change, both by providing the necessary tools and by handling the large quantities of data these analyses require. The most widely used moderate-resolution sensors, onboard the Landsat satellite platforms, often require pre-processing to prepare the data for analysis. This data set consists of Australia-wide Landsat derived Normalised Difference Vegetation Index (NDVI) values for the years 2001-2019. The median annual NDVI value for each Statistical Area 1 (SA1) and Statistical Area 2 (SA2) were calculated, and statistics for this imagery is provided in a tabular format. The accompanying Google Earth Engine script applies the pre-processing steps required to account for sensor, solar and atmospheric effects, improving continuity between imagery across space and time and therefore, will enable researchers beyond the remote sensing community to access analysis-ready imagery for the moderate resolution Landsat and Sentinel-2 satellite platforms.

Concept Paper: Re-Imagining Benchmarking as Stewards of Place: Identifying Peers in the Context of Communities
Authors: Medlin Kristin , Norris Kristin , Janke Emily
Published: July 2021

What constitutes a “peer” for institutions that consider themselves to be Stewards of Place and who want to understand their impacts within the context of their community partnerships? This concept paper introduces the idea of Placemarking, which radically reorients the institution as a member of the communities it serves rather than identifying it as a separate entity beyond the boundaries of its community. It enhances traditional benchmarking methodologies and metrics (e.g., IPEDS) to also include the community context in which institutions reside (socioeconomic and demographic indicators) as well as how institutions work in partnership with their communities (e.g., its people, organizations, issues, and assets). Placemarking allows institutions to better align their identity and image, advocate on behalf of both institutional and community priorities, and foster collaborative planning.
“Now it’s your turn to speak up!” - Burdens and Psychosocial Consequences of the COVID-19 pandemic for Austrian Children and Adolescents
Authors: Schabus Manuel , Eigl Esther-Sevil
Published: July 2021

The survey “Now it’s your turn to speak up!” evaluates the psychosocial burden and impairments of children and adolescents in Austria during the ongoing COVID-19 pandemic. Using an online-questionnaire, 5483 children and adolescents between 6 and 18 years shared their feelings, fears, worries and thoughts regarding the coronavirus pandemic. Most of them report a high degree of fear due to the current situation, with especially female participants being under more emotional strain than their male counterparts. Associated to this, the risk of a COVID-19-associated hospitalization is strongly overestimated, as previously found in adults. In addition, an alarming lack of perspective during the ongoing pandemic is evident across all age groups including the youngest participants aged 6-10 years. Feelings of fury, anger, loneliness, and sadness are reported much more frequently than previously. Last but not least, our study shows an alarming reduction of sleep quality and a drastic increase in self-reported sleep problems already in this young population. The results of the “Jetzt Sprichst Du!” survey emphasize the need for immediate action in order to limit the collateral damage caused on the psychosocial, developmental and health dimension as far as this is still possible today.
Imitation and interindividual differences: Belief in free will is not related to automatic imitation
Authors: Westfal Mareike , Crusius Jan , Genschow Oliver
Published: July 2021

It is well known that individuals have the tendency to automatically imitate each other and that such imitative behavior is fostered by perceiving intentions in others’ actions. That is, past research has shown that perceiving an action as internally driven enhances the shared representation of observed and executed actions increasing automatic imitation. An interpersonal factor that increases the perception that a behavior is internally driven is belief in free will. Consequently, we hypothesized that the more individuals believe in free will, the more they automatically imitate others. To test this prediction, we conducted two high-powered (total N = 642) and preregistered studies in which we assessed automatic imitation with the imitation-inhibition task. Contrary to our predictions, belief in free will did not correlate with automatic imitation. This finding contributes to current findings challenging the assumption that automatic imitation is modulated by interindividual differences. Further theoretical implications are discussed.
More and Better: Reappraisal Quality Partially Explains the Effect of Reappraisal Use on Changes in Positive and Negative Affect
Authors: Southward Matthew W. , Holmes Anne C. , Strunk Daniel , Cheavens Jennifer S.
Published: July 2021

Background: A substantial body of research suggests that cognitive reappraisal is effective at improving momentary affect, but it remains unclear how reappraisal leads to these changes. We tested the quality of reappraisal as one potential mechanism. Methods: A sample of 314 participants (Mage = 36.30; 51.0% female; 69.4% White) recruited online were instructed in the use of reappraisal and were asked to use reappraisal while recalling an upsetting memory for five minutes. Afterwards, participants rated the degree to which they used reappraisal during the task and independent raters coded the quality of participants’ written descriptions. Participants also rated the intensity of positive and negative affect before and after the memory task. Results: Reappraisal quality explained a significant proportion of the effect of reappraisal use on improvements in negative, ab = –1.49, SE = .33, 95% CI [–2.17, –.90], and positive affect, ab = 2.67, SE = .54, 95% CI [1.64, 3.79]. Depression symptom severity moderated these relations – the indirect effects of reappraisal quality were stronger among those with fewer depressive symptoms. Conclusions: These results suggest the quality with which reappraisal is used is one way through which reappraisal predicts improvements in affect, especially among people lower in depressive symptoms. Our findings enhance our understanding of the process of reappraisal and offer potential targets for interventions.
Word Aversion: Why people dislike moist more than moose, but not as much as merts
Authors: Bosley Hannah G , Eagleman David M.
Published: July 2021

Moist is a common example of a word that triggers aversion or disgust responses in many people. Word aversion presents a novel opportunity to empirically study the link between linguistic features (phonology, semantics) and emotional response. In the present study, we (1) determine the prevalence and extent of aversions to specific words in a large cohort, (2) examine phonological predictors of emotional response in word aversion, and (3) test the effect of phonological-emotional mapping on processing in an object-labeling paradigm. Across 244 participants, individuals tended to rate a subset of commonly self-reported aversive words (e.g. slacks) as more aversive than matched control words. However, participants reported even stronger aversions to nonsense words, suggesting that familiarity may moderate the experience of word aversion. Results also suggest that word-averse individuals make associations between phonology and meaning more readily.
Modelling Clusters From The Ground Up: A Web Data Approach
Authors: Stich Christoph , Tranos Emmanouil , Nathan Max
Published: July 2021

This paper proposes a new methodological framework to identify economic clusters over space and time. We employ a unique open source dataset of geolocated and archived business webpages and interrogate them using Natural Language Processing to build bottom-up classi- fications of economic activities. We validate our method on an iconic UK tech cluster – Shoreditch, East London. We benchmark our results against existing case studies and admin- istrative data, replicating the main features of the cluster and providing fresh insights. As well as overcoming limitations in conventional industrial classification, our method addresses some of the spatial and temporal limitations of the clustering literature.
Local News Monopolies Increase Misperceptions about Immigration
Authors: Hilbig Hanno , Riaz Sascha
Published: July 2021

We examine how local news monopolies affect misperceptions about the size of the immigrant population in Germany. We propose a theoretical framework in which heterogeneous information from different local news outlets diffuses through social interactions. We posit that indirect exposure to information from multiple sources leads to more accurate beliefs in competitive markets. To causally identify the effect of local news monopolies on misperceptions, we exploit overlapping newspaper coverage areas as a source of exogenous variation in the number of available outlets. We estimate that local news monopolies increase misperceptions about the size of the local immigrant population by about four percentage points. We demonstrate that the effect of media monopolies hinges on social interactions. For individuals with fewer close social contacts, misperceptions remain unaffected by local news monopolies. Our results suggest that consolidation in the market for news decreases constituents' knowledge about critical policy issues.
The Effects of Publishing Processes on Scientific Thought. Typography and Typology in Prehistoric Archaeology (1950s–1990s)
Authors: Plutniak Sébastien
Published: July 2021

In the last decades, many changes have occurred in scientific publishing, including online publication, data repositories, file formats and standards. The role played by computers in this process rekindled the argument on forms of technical determinism. This paper addresses this old debate by exploring the case of publishing processes in prehistoric archaeology during the second part of the twentieth century, prior to the wide-scale adoption of computers. It investigates the case of a collective and international attempt to standardize the typological analysis of prehistoric lithic objects, coined typologie analytique by Georges Laplace and developed by a group of French, Italian, and Spanish researchers. The aim of this paper is to: 1) present a general bibliometric scenario of prehistoric archaeology publishing in continental Europe; 2) report on the little-known typologie analytique method in archaeology, using publications, archives, and interviews; 3) show how the publication of scientific production was shaped by social (editorial policies, support networks) and material (typography features and publication formats) constraints; and 4) highlight how actors founded resources to control and counterbalance these effects, namely by changing and improving publishing formats.
Spatial Distribution of Fluoride in Drinking Water in Dhamar City, Yemen
Authors: Al Aizari Hefdhallah , Fegrouche Rachida , Aizari Ali Al , Albaseer Saeed S.
Published: July 2021

The fact that groundwater is the only source of drinking water in Yemen mandates strict monitoring of its quality. The aim of this study was to measure the levels of fluoride in the groundwater resources of Dhamar city. Dhamar city is the capital of Dhamar governorate located in the central plateau of Yemen. For this purpose, fluoride content in the groundwater from 16 wells located around Dhamar city was measured. The results showed that 75% of the investigated wells contain fluoride at or below the permissible level set by the World Health Organization (0.5 – 1.5 mg/L), whereas 25% of the wells have relatively higher fluoride concentrations (1.59 – 184 mg/L). The high levels of fluoride have been attributed to the anthropogenic activities in the residential areas near the contaminated wells. Interestingly, some wells contain very low fluoride concentrations (0.30 – 0.50 mg/L).  Data were statistically treated using the principal component analysis (PCA) method to investigate any possible correlations between various factors. PCA shows a high correlation between well depth and its content of fluoride. On the other hand, health problems dominating in the study area necessitate further studies to investigate any correlation with imbalanced fluoride intake.
Water Beetles: Species Diversity and Response to Physico-Chemical Parameters in Different Freshwater Habitats in Samtse, Bhutan
Authors: Ghalley Tez Bdr , Dorji Ugyen , Dorji Cheten , Nepal Arjun , Shacha Namgay
Published: July 2021

Bhutan is located between the two zoogeographic regions which are assumed to be rich in diversity of water beetles. The study aimed to determine the diversity and distribution pattern of water beetles in different freshwater habitats in Namgaychholing under Samtse district, Bhutan. The study also analysed the association of water beetles with the physico-chemical parameters. The data were collected from four different habitats with sample plot of 3 m × 1 m for a standard time of 1 hour in every plot. A total of 30 species belonging to 7 families were recorded of which Dytiscidae (n=626, RA=51) was the most abundant family and Lacconectus basalis (n=416, RA=34.13) was the most abundant species. The overall Shannon diversity index of the study area was H ′=2.48. Amongst the different habitats, marshy area had the highest Shannon diversity index (H ′=2.45) and stream had the lowest (H ′=1.82). A Kruskal Wallis test on diversity among different habitats showed no significant difference (p<.05). Through a cluster analysis, the species composition between the river and waterlogged showed 100% similarity index. Canonical correspondence analysis showed temperature as a main determining factor affecting the distribution of water beetles. With broad families encompassing the water beetles, similar study on water beetles in different regions of the country is recommended with particular emphasis on different families. Moreover, Bhutan falls in junction of Palearctic and Oriental Zoogeographic regions, which are known to be rich in diversity of water beetles. Hence, study in high-altitude lakes, which are assumed to be rich in diversity of water beetles are recommended despite social beliefs to keep lakes isolated and undisturbed.
Temporal Variability of Soil Reaction Among Surface and Near-Surface Horizons of Soils of Dissimilar Lithology in a Humid Tropical Environment
Authors: Onweremadu Emmanuel , Aririguzo Bernadine , Okoli Nnaemeka , Afangide Isaiah
Published: July 2021

The study investigated changes in soil reaction among surface and near surface horizons of four soil groups as affected by wet and dry seasons in Southeastern Nigeria. A geological map of the area guided soil sampling. Free survey approach was used in locating soil profiles. Soil samples were collected based on horizon differentiation and samples were collected from the AB-horizon (near-surface) and the A-horizon (Surface). Routine laboratory analyses were conducted on these soil samples after sieving through a 2-mm sieve. Data were subjected to analysis of variance (ANOVA) using SAS Statistical Computer Package. There were significant (p<0.05) changes in soil reaction in A- and AB-horizons in the dry seasons of 2016 and 2017.  Similarly, in the wet season, soil pH varied significantly (p<0.05) in 2016 and 2017. Soil reaction significantly (p<0.05) differed in AB-horizons in both 2016 and 2017 irrespective of the season. All soil samples were acidic irrespective of lithologic material and season with pH values ranging from 4.20-5.60 and 3.31-5.42 in the A- and AB-horizons, respectively.
“Be proactive not reactive”: Understanding gaps in student sexual consent education
Authors: Thiessen Brittany , Williamson Linzi , Buchanan Carie M.
Published: July 2021

A growing number of universities are providing sexual violence prevention programs to students in recognizing the need for this programming. While universities favour programs on singular topics aimed at preventing sexual violence, scholars have argued that comprehensive sexual health education should begin prior to entering university to better ensure safer campus communities. Further, students have expressed unmet needs regarding the sexual health education they received prior to attending university. Therefore, the current study sought to explore gaps in sexual health education as identified by university students. Participants ( N = 444) were asked to describe the consent definition they were taught in high school and from their parents, and how the sexual health education they received could have been improved. An inductive thematic analysis was used to identify six themes from the data: back to consent education basics, you have the power to set boundaries, staying safe in sexual situations, take a sex-positive approach with sex education, wholistic education on consent-based relations, and practical recommendations for providing sex education. Findings highlight that participants desired a more wholistic approach to their sexual health education that included practical components on healthy sexuality. Notably, participants relayed how proper sexual health education may have prevented experiences of sexual violence they had. Thus, it is essential to continue exploring how best to provide comprehensive sexual health education to adolescents.

«INDUSTRIAL BIROBIDZHAN IS GROWING»: TWO EXHIBITIONS IN MOSCOW AND LENINGRAD DEDICATED TO JEWISH ECONOMIC AND CULTURAL CONSTRUCTION IN THE USSR IN 1930S
Authors: Ivanov A.I.
Published: July 2021

The author of the article considers two exhibitions dedicated to the Soviet propaganda project for the radical reconstruction of the Russian Jewry socio-economic structure. The first one – «Birobidzhan» – was held in 1933 in a pavilion of the Maxim Gorky Central Park of Culture and Rest in Moscow. Another exhibition – «Jews in Tsarist Russia and in the USSR», organized by the Jewish section of the State Museum of Ethnography (now – the Russian Ethnographic Museum) was working in Leningrad for the period from 1939 to 1941. Based on the documents stored in the Scientific Archive of the Russian Ethnographic Museum, the author shows how the Soviet propaganda machine used the demonstration material of museums in 1930s. The entire arsenal of exhibition was used to demonstrate «the achievements of the Leninist-Stalinist national policy among the Jews of the USSR», a creation of the Jewish Autonomous Region in the Soviet Far East being a major one.

In social network science, Facebook is one of the most interesting and widely used social networks and media platforms. Its data has significantly contributed to the evolution of social network research and link prediction techniques, which are important tools in link mining and analysis. This paper gives the first comprehensive analysis of link prediction on the Facebook100 network. We stu- dy performance and evaluate multiple machine learning algorithms on different feature sets. To derive the features, we use network embeddings and topology-based techniques such as node2vec and vectors of similarity metrics. In addition, we also employ node- -based features, which are available for the Facebook100 network, though rarely found in other datasets. The adopted approaches are discussed and results are clearly presented. Lastly, we compare and review the applied models, where overall performance and classification rates are presented.

Thus, summarizing our scientific research, we can clearly emphasize that theatrical art flourished in Artsakh in the second half of the 19th century and the beginning of the 20th century. It should be noted that until the second half of the 19th century, the Armenians of Artsakh had their theatrical traditions for centuries. There was theater in dance art, at parties and events. But there was no professional theater yet, preconditions were created for that only when in 1865 famous figures of the Armenian theater Gevorg Chmshkyan, Mihrdat Americyan and Sedrak Mandinyan came to Shushi. And the Mkrtich Khandamiryan Theater was built in Shushi in 1891. It had a 350-seat hall. 

Separate issues related to the socio-economic, political and cultural events in Artsakh were covered in almost all issues of the three-day literary-social newspaper "Karabakh". Covering the theatrical art of Artsakh in 19111912, the newspaper emphasized that the theater continued to flourish in that period. Theatrical performances took place in different parts of Artsakh. A number of interesting and multi-genre theatrical performances took place at the Diocesan school of Shusha, at the Mariamyan girls 'school, at the Hripsimyan girls' school, at the school of the Saint Astvatsatsin church of Aguletsots, at the school of boys of the Saint Astvatsatsin church of Megretsots, at the Mariam-Ghukasyan school, at the school of Realakan.

HAPPINESS AS A DOUBLE GESTURE OF A TRIGGER: BREAKING AND CONCEPTING
Authors: Bilchenko E.
Published: July 2021

The background of the study is an existential psychological analysis of the phenomenon of happiness as a state of radical break with the dominant signifiers of symbolic hegemony and, at the same time, voluntary value filling of the formed vacuum in the symbolic structure of a split subject with new meanings corresponding to his self. Research methods: structural psychoanalysis, poststructuralism, semiotics of culture, hermeneutics, philosophical comparative studies, deconstruction and universal ethics, theological methods of correlation between secular and religious models of thinking. Research results: comparison of the positive ontology of happiness in the Eastern Slavic Christian classical thought and the negative ontology of happiness in the Western post-Lacanian postmodernity; the implementation of the synthesis of images of happiness in the ways of thought of the postmodern West and the modern East on the basis of the dialogue of universalism and particularism, traditionalism and neo-modernism, personalism and collectivism. Conclusions: confirmation of the hypothesis of the double nature of happiness as a unity of metaphysical rupture and dialectical synthesis, manifested through the chronotopes of secular and religious cultures, traditions and innovations.

Cabinet of Curiosities, a Dwelling Place

This Instagram “Weekly Writing” assignment is a social-media-based, low-stakes, and longitudinal approach to teaching and experimenting with multimodal composition. Students create an account for the purposes of the class and follow each other. They post three times per week, sometimes freely and sometimes in response to a prompt or challenge. Together, we use the platform and its rich multimodal resources to consider how in-the-moment multimodal composing can spur invention, place the writer in the perpetual position of noticing, and create an archive of experience that holistically communicates beyond the author’s original intention. This article discusses the pedagogical rationale for this approach, along with the issues to consider before adopting and adapting this practice.
