Columnar storage and list-based processing for graph database management systems
Authors: Gupta Pranjal , Mhedhbi Amine , Salihoglu Semih
Published: October 2021

We revisit column-oriented storage and query processing techniques in the context of contemporary graph database management systems (GDBMSs). Similar to column-oriented RDBMSs, GDBMSs support read-heavy analytical workloads that however have fundamentally different data access patterns than traditional analytical workloads. We first derive a set of desiderata for optimizing storage and query processors of GDBMS based on their access patterns. We then present the design of columnar storage, compression, and query processing techniques based on these desiderata. In addition to showing direct integration of existing techniques from columnar RDBMSs, we also propose novel ones that are optimized for GDBMSs. These include a novel list-based query processor, which avoids expensive data copies of traditional block-based processors under many-to-many joins, a new data structure we call single-indexed edge property pages and an accompanying edge ID scheme, and a new application of Jacobson's bit vector index for compressing NULL values and empty lists. We integrated our techniques into the GraphflowDB in-memory GDBMS. Through extensive experiments, we demonstrate the scalability and query performance benefits of our techniques.
Explaining inference queries with bayesian optimization
Authors: Lockhart Brandon , Peng Jinglin , Wu Weiyuan , Wang Jiannan , Wu Eugene
Published: October 2021

Obtaining an explanation for an SQL query result can enrich the analysis experience, reveal data errors, and provide deeper insight into the data. Inference query explanation seeks to explain unexpected aggregate query results on inference data; such queries are challenging to explain because an explanation may need to be derived from the source, training, or inference data in an ML pipeline. In this paper, we model an objective function as a black-box function and propose BOExplain, a novel framework for explaining inference queries using Bayesian optimization (BO). An explanation is a predicate defining the input tuples that should be removed so that the query result of interest is significantly affected. BO --- a technique for finding the global optimum of a black-box function --- is used to find the best predicate. We develop two new techniques (individual contribution encoding and warm start) to handle categorical variables. We perform experiments showing that the predicates found by BOExplain have a higher degree of explanation compared to those found by the state-of-the-art query explanation engines. We also show that BOExplain is effective at deriving explanations for inference queries from source and training data on a variety of real-world datasets. BOExplain is open-sourced as a Python package at https://github.com/sfu-db/BOExplain.

Published: October 2021

Access to high-quality data repositories and benchmarks have been instrumental in advancing the state of the art in many experimental research domains. While advanced analytics tasks over time series data have been gaining lots of attention, lack of such community resources severely limits scientific progress. In this paper, we present Exathlon, the first comprehensive public benchmark for explainable anomaly detection over high-dimensional time series data. Exathlon has been systematically constructed based on real data traces from repeated executions of large-scale stream processing jobs on an Apache Spark cluster. Some of these executions were intentionally disturbed by introducing instances of six different types of anomalous events (e.g., misbehaving inputs, resource contention, process failures). For each of the anomaly instances, ground truth labels for the root cause interval as well as those for the extended effect interval are provided, supporting the development and evaluation of a wide range of anomaly detection (AD) and explanation discovery (ED) tasks. We demonstrate the practical utility of Exathlon's dataset, evaluation methodology, and end-to-end data science pipeline design through an experimental study with three state-of-the-art AD and ED techniques.

Published: October 2021

This review gives an overview of current trends in the investigation of confined molecules such as higher alcohols, ethylene glycol and polyethylene glycol as guest molecules in neat and functionalized mesoporous silica materials. All these molecules have both hydrophobic and hydrophilic parts. They are characteristic role-models for the investigation of confined surfactants. Their properties are studied by a combination of solid-state NMR and relaxometry with other physicochemical techniques and molecular dynamics techniques. It is shown that this combination delivers unique insights into the structure, arrangement, dynamical properties and the guest-host interactions inside the confinement.

Authors: Xiao Rong-Xue , Wang Xu , Gao Jun-Qing , Liu Zong-Jun
Published: October 2021

Objective: To evaluate the clinical efficacy of a drug-eluting stent (DES) combined with a drug-coated balloon (DCB) in the treatment of left main coronary artery bifurcation lesions.

Methods: A retrospective analysis was conducted on the clinical data of eight patients with left main coronary artery bifurcation lesions treated with a DES combined with a DCB who were admitted to our hospital from July 2016 to July 2017. These eight patients all underwent DES treatment for their left main coronary artery and left anterior descending coronary artery lesions, and DCB treatment at the ostium of the left circumflex artery; six of the patients underwent surgical procedures under the guidance of intravascular ultrasonography. Immediate postoperative angiography was used to evaluate the patency of the diseased vessels, and the restenosis rate at the 6-month follow-up after the operation and the incidence of serious clinical events within 6 months were assessed as well.

Results: The use of a DES combined with a DCB in the treatment of left main coronary artery bifurcation lesions had a low restenosis rate (left main coronary artery (8.4 ± 5.3)%, left anterior descending coronary artery (18.2 ± 5.0)%, left circumflex artery (30.5 ± 16.5)%). No serious clinical events occurred in any patients.

Conclusion: A DES combined with a DCB is a safe and effective interventional treatment for left main artery coronary bifurcation lesions.
Social Research about Online Crime: Global Range of Topics and a Systematic Analysis of Research in Lithuania
Authors: Šupa Maryja
Published: October 2021

Social research about online crime is a multi-disciplinary field addressing a wide array of topics since its inception in the 1980s. Based on a broad review of state-of-the-art literature and gaps identified in review publications (Holt, Bossler 2014; Stratton, Powell, Cameron 2017; Maimon, Louderback 2019, and others), in this paper I outline 41 key topic in social research about online crime, classified into four broad categories: 1) research focusing on specific types of online crime, 2) research about perpetrators, victims, and law enforcement, 3) research about online crime discourses and public perceptions, 4) research putting the local and global specifics of online crime into perspective. Based on the topic map, I undertook a systematic review of literature on research about online crime published in Lithuania from the empirical social scientific perspective. The results show that very few such studies are carried out in Lithuania. From 2004 to 2020, 26 publications have been found in total. 10 of them were theoretical briefs, while 16 were based on empirical data. Out of the 41 key topic, 14 were covered in the publications, while 29 or roughly two thirds remained unaddressed. The dominant contributors were legal scholars writing about the social aspects of online crime across a variety of topics, and mostly focusing on specific crime types. The most developed topic was cyberbullying, with contributions by scholars mostly from the fields of psychology and education. To fill in these glaring gaps, it is vital to develop this field of research with an emphasis on both wider and deeper research agendas, complex, valid and reliable research data and critical theoretical approaches, inviting systematic contributions from criminology, sociology, communication and media studies, and political science.

As most evidence for mental health impacts of the COVID-19 crisis is cross-sectional, the present study aimed to analyze the longitudinal development of psychological suffering among 619 Brazilian adults by assessing mental health outcomes and individual factors in two periods: a year before and a month after the break of the pandemic. As major findings, pandemic psychological suffering was directly explained by previous-year suffering, conscientiousness, and pandemic perceived stress, and correlated with pandemic suicidal ideation. Pandemic perceived stress correlated with pandemic psychological distress, and was explained by previous-year suffering, neuroticism, and conscientiousness, as well as by pandemic life satisfaction and perceived pandemic impact. Finally, pandemic suicidal ideation variance was explained by prior ideation and pandemic life satisfaction. These findings are in line with current models of mental health and highlight the importance of integrating both more stable individual factors and more transient variables towards and explanation for mental health outcomes.
Seed mass maturity in the terrestrial bromeliad Hechtia perotensis (Bromeliaceae), endemic to Mexico
Authors: Elizalde Violeta , García José Rodolfo , Trejo Carlos , Peña-Valdivia Cecilia Beatriz , Ybarra Ma. Carmen , Leyva Otto Raúl
Published: October 2021

Introduction: H. perotensis is a plant with a high potential for ecological restoration because it yields thousands of seeds and grows under low levels of rain, poor soils and contrasting temperatures. However, little is known of the seed mass maturity (high seed germination, low seed fresh weight and low seed moisture content) in this species. Objective: Assess seed germination in the laboratory of H. perotensis during seed development and along the floral stalk (infructescence) in two sites one in rocky location and another near a lake. The hypothesis was that there is a time after flowering in which seeds have highest germination and fresh weight and that the apical, centre and base of the infructescence are different in seed germination and fresh weight in both sites. Methods: Capsules were collected in two sites one in rocky land (Frijol Colorado, Perote, Veracruz) and another near one lake (Alchichica, Puebla), in the months of August, September and November 2016 and January 2017. A repeated measure design (RMD) was used to analyze the effects of infructescence section on seed weight, moisture content and seed germination (41, 87, 152 and 215 days after flowering). Each evaluation time comprised five replicates, each one with 15 seeds. Results: Difference in seed germination, seed weight and moisture content between sections of the infructescence was not significant. However, significant differences were found not only between first and last sample dates, buy mainly between first and second dates. Eighty-seven days after flower pollination seed moisture content was lower than 20 % and up to 80 % of seed germinated in both sites of sampling. Conclusions: In this study it was found that the moisture content of H. perotensis seed can be used as an indicator of the physiological maturity of the seed and it is also related to germination of the seed.
Histology and structure of the testicles in three species of Atelopus frogs (Anura: Bufonidae) endemic to the Sierra Nevada de Santa Marta, Colombia
Authors: Sánchez-Ferreira Arantxa , Rincón-Barón Edgar J. , Rueda-Solano Luis A.
Published: October 2021

Introduction: Testicular histology constitutes one of the least explored aspects in frogs of the genus Atelopus. This taxonomic group shows an alarming population decline; therefore, its reproductive biology is one of the greatest topics of interest for its conservation. Objective: To describe the testicular morphology and the spermatogenetic lineage cells in adult males of Atelopus laetissimus, Atelopus nahumae, and Atelopus carrikeri in the Sierra Nevada de Santa Marta, Colombia. Methods: During June – July 2017 and 2018, sampling was conducted in the localities of San Lorenzo and Páramo Cebolletas, Sierra Nevada de Santa Marta (SNSM), to collect 15 adult males, 5 per species. Testes samples were fixed in Bouin to be processed by the standard paraffin-embedding technique. Histological sections (3 mμ) were stained with Hematoxylin-eosin and Mallory-Heidenhain-Azan-Gomori's. For the description and photographic register of the germ cells, the photonic microscopy technique was used with the differential interference contrast system. Results: The testes are oval organs, compact, light yellow color, and with little vascularization. Externally, they are surrounded by a thin albuginea tunic constituted by regular dense connective tissue. Inside this layer, they are composed of numerous seminiferous tubules of hexagonal contour, in which germ cell cysts are distinguished at different stages of spermatogenesis (spermatogonia I and II, spermatocyte I and II, and early and late spermatids) and spermiogenesis (spermatozoa in fascicles and free spermatozoa). Separating the seminiferous structures is the interstitial tissue in which Leydig cells and blood vessels stand out. Additionally, in the cranial part of the testis, the Bidder's organ was found, formed by two distinguishable regions, the cortex and the medulla. In the cortex, there are previtellogénic oocytes of different sizes surrounded by a monolayer of flat follicular cells. For its part, the medullary region is the connective tissue that nourishes the oocytes and is constituted by blood capillaries. Conclusions: The gonads of the three species analyzed present a cystic cellular organization similar to other anurans, where all stages of spermatogenesis and spermiogenesis were identified, possibly indicating a continuous reproductive activity. Likewise, the Bidder’s organ is reported for the first time in the three Atelopus species, which allows suggesting a possible sexual reversion in case of a population decrease of females as a reproductive strategy.
Ant diversity sampling in the Brazilian Amazon: a comparison of litter collection and pitfall trapping
Authors: Da Silva Wully B. , Cajaiba Reinaldo L. , Périco Eduardo
Published: October 2021

Introduction: Ants in tropical forests are a hyper-diverse group that plays important ecological roles. Several studies on tropical forests have used different sampling protocols to capture soil ants, making it difficult to compare responses and patterns of diversity between studies. Thus, research that compares different well-structured and standardized sampling methodologies to adequately estimate the richness of ant species in tropical forests is necessary. Objective: In this study, we examined the combination of catches with pitfall traps with and without baits and litter collections for soil ant sampling. Methods: In the fall traps, we use two baited (sardines and bananas) and one non-baited. For the manual collections (litter sampling), the litter and only the topsoil of the loose soil were collected. Results: We found that traps containing sardine baits collected a greater abundance of ants, whereas non-baited traps collected a greater richness of ant species. On the other hand, litter collections captured the largest number of exclusive species, presenting a different species composition from the pitfall traps (with and without baits). In general, baited traps showed greater abundance in more degraded locations, while manual collections and unbaited pitfalls captured more individuals in preserved environments. Conclusions: Our results provide evidence that, for accurate sampling of soil ant assemblages in tropical forests, the use of different methodologies is necessary to capture a greater diversity of species because the methods differ in effectiveness according to habitat.
Effectiveness of aerial wildlife crossings: Do wildlife use rope bridges more than hazardous structures to cross roads?
Authors: Laidlaw Katra , Broadbent Eben , Eby Stephanie
Published: October 2021

Introduction: Although wildlife crossing structures have proven successful at reducing wildlife-vehicle collisions and linking fragmented habitat, their ability to prevent electrocutions of arboreal wildlife has not been closely examined. Objective: To evaluate the effectiveness of aerial rope bridges in restoring habitat connectivity for arboreal species in Manuel Antonio, Costa Rica, while preventing electrocutions by determining 1) what species are using the rope bridges and 2) whether wildlife prefer to use rope bridges instead of other hazardous structures that cross the roads (such as telephone cables, which are often in close proximity to electric wires). Methods: From January to May 2016, nine rope bridges along the highly-trafficked main road that extends from Quepos to Manuel Antonio, Costa Rica, were monitored using camera traps, and ten rope bridges were observed directly along a paved side road off the main road. Results: A total of 11 species were seen using the bridges, and 1 540 crossings were witnessed via camera traps and observations (1 234 via camera traps, 306 during observations). Results from a paired t-test showed no significant difference in the average number of individuals crossing the road via rope bridges versus telephone cables (t(8) = 1.027, P = 0.334). Conclusions: Rope bridges are used by a variety of arboreal wildlife species with a high degree of frequency; however, due to the equally high usage of telephone cables by arboreal wildlife, they are insufficient to prevent wildlife electrocutions on their own. Rope bridges should be installed in tandem with other methods to prevent electrocutions, such as insulating electric wires, to facilitate the safe passage of wildlife over roads.
Your politeness is my impoliteness
Authors: Okamoto Shigeko
Published: October 2021

It is often noted that usage of Japanese honorifics has been changing over the years (see, for example, Keigo no Shishin ‘Guidelines on honorifics’, Kokuritsu Kokugo Kenkyujo 2007), Yet, ‘average’ Japanese adults are expected to use honorifics correctly, observing their rules, or grammar. But do they all share the same understanding of honorific rules, especially given the ongoing change in usage? If they do not, why? What are its consequences? To address these questions, this study examines native speakers’ metapragmatic comments on honorifics expressed in blogs. In particular, it focuses on their understandings of grammatical categories and indexical meanings of honorifics – a topic largely understudied. The analyses show wide diversity in the interpretation of same honorific forms, including contrary interpretations concerning politeness, which is highly related to the divergent understandings of honorific categories, the ambiguity of concepts such as respect and politeness, and language ideologies that mediate honorific forms and their meanings.
Absent appreciation in Mandarin Chinese interaction
Authors: Liang Hongyan
Published: October 2021

When receiving something beneficial, interlocutors are expected to express their appreciation in the second pair part (SPP) or the sequence-closing third position with linguistic resources such as ‘thanks’ and ‘thank you’, thus forming an adjency pair or a complete sequence. However, under some circumstances, relevant or appropriate appreciation is expected but does not appear. Adopting conversation analysis as the research methodology, this article examines the absence of appreciation in ordinary Mandarin interactions where gratitude and appreciation are often socially prescribed. Its sequential analysis of talks demonstrates that at times a verbal appreciative response in situations such as offering and requesting does not occur until a later conversational turn rather than in the preferred second pair part, whereas at other times the social action, although expected, is actually absent in social interaction. The analysis of the data shows that when interlocutors transgress the normative expectation of appreciation, the expected pattern of action and interactional organisation will be evidenced circumstantially within the ongoing interaction itself. The present study proves that deviations from standard forms in the interactional organisation can give rise to additional accounts or other visible interactional behaviour.

Published: October 2021

Abstract: Performance measurement is considered a critical strategic process for companies operating in the logistics sector, as they need to perform high service levels under conditions of uncertainty. In this context, the present study aimed to evaluate the process of performance measurement in a multinational 3PL provider with a subsidiary in Fortaleza, Ceará. 31 indicators used by the company were identified and described, and its process of performance measurement was mapped. It was found that the company does not have a clear and well-structured process for performance measurement, which can lead to misinterpretations and management failures. In addition, the decision-making process proved to be mostly centered on the individual experience of employees, who might make decisions not aligned with the organizational objectives. The study discusses some manners to improve the process of performance measurement in the case investigated and proposes opportunities for further research in the field.
Novel application of machine learning for estimation of pullout coefficient of geogrid
Authors: Pant A. , Ramana G.V.
Published: October 2021

Pullout behaviour of geogrids is critical to understand for the design of mechanically stabilized earth walls. The pullout coefficients are determined through laboratory testing on geogrids embedded in structural fill. Random forest (RF) is a data-driven ensemble learning method that uses decision trees for classification and regression tasks. In the present study, the use of the RF regression technique for estimation of pullout coefficient of geogrid embedded in different structural fills and at variable normal stress based on 198 test results has been investigated using five-fold cross-validation. 80% of the data has been trained on the model algorithm and the accuracy of the model is then tested on 20% of the remaining dataset. The performance of the model has been checked using statistical indices, namely R2, mean square error, as well as external validation methods. The validity of the model has also been checked against laboratory tests conducted on geogrid embedded in four different fills. The results of the RF model have been compared to results obtained with three other regression models, namely, Multivariate Adaptive Regression Splines, Multilayer Perceptron, and Decision Tree Regressor. The results demonstrate the superiority of the RF-based regression model in predicting pullout coefficient values of geogrid.
Effect of temperature on the mechanical properties of two polymeric geogrid materials
Authors: Desbrousses R. L. E. , Meguid M. A. , Bhat S.
Published: October 2021

Understanding the tensile behavior of geosynthetic reinforcement materials at different temperatures is essential for the design of reinforced soil structures in seasonally cold regions. This study describes a series of tensile tests performed on two polypropylene geogrid materials, namely a biaxial geogrid and a geogrid composite. A total of 84 tests were performed in an environmental chamber with temperatures as low as −30°C and as high as +40°C. The response of each material is examined over the range of investigated temperatures to evaluate the effect of temperature changes on the tensile strength of the two geogrid materials. The response of the biaxial geogrid is found to be sensitive to temperature variations, with samples tested at low temperatures exhibiting brittle behavior characterized by high rupture strength and small ultimate strain while samples tested at elevated temperatures displayed ductile behavior with large elongation at failure and comparatively small rupture strength. A similar response was found for the geogrid composite, however, the rupture strength seemed to be less sensitive to temperature changes. The modes of failure observed at each temperature are examined based on photographic evidence taken during the experiments.

Published: October 2021

This paper addresses unpaved and paved roads improved with geosynthetics, such as geotextiles, geogrids and geocells. The paper examines the mechanisms associated with the use of geosynthetics to improve roads, describes the principles of the design methods used to quantify the benefits of geosynthetics used in unpaved and paved roads, presents case histories to demonstrate the use of geosynthetics to solve challenging road problems, and discusses the relevance of tests and trials to real roads. This paper is supplemented by four presentations in pdf format that contain more than 800 slides. These four presentations are updated versions of the four presentations made during a one-day short course at the 11th International Conference on Geosynthetics held in Seoul, Korea, in September 2018. The paper that follows contains a summary of each of the four presentations, with special emphasis on key issues.
Analysing shear strength of reinforced concrete beams using a meso-scale finite-element method
Authors: Lim Jin-Sun , Jeong Young-Do , Park Yon-Dong , Choi Sokhwan , Yi Seong-Tae
Published: October 2021

An analytical exploration of the effects of shear span-to-depth ratio on the shear strength of reinforced concrete beams was carried out using a meso-scale finite-element method. Prior to the numerical analysis, a method of defining concrete as meso-scale composites of multi-phases was described. The concrete was assumed to be a composite with three phases (aggregates, cement matrix and interfacial transition zone), and the material properties of each phase were applied for the numerical analysis. The shear failure behaviour of reinforced concrete beams was examined by the numerical model that was constructed, and the effect of span-to-depth ratio on shear strength was confirmed through these analyses. An investigation of cases where span-to-depth was less than 1.0 was also carried out. Moreover, the performance of the numerical model was evaluated by comparing the numerical results with the experimental results obtained from the model code and other researchers. It was confirmed that the application of a meso-scale finite-element method was appropriate for the study on the effect of span-to-depth ratio on shear strength and the occurrence and progress of bending and shear cracks.

Capitalismo de vigilância: a vertente Mattelart e a crítica aos processos midiáticos
Authors:   Universidade do Vale do Rio dos Sinos, Kalikoske Andres
Published: October 2021

O artigo analisa o trinômio comunicação, capitalismo e sistemas de vigilância no âmbito dos processos midiáticos, recuperando as relações estabelecidas entre esses elementos desde as contribuições teórico-metodológicas de Armand Mattelart. A partir de uma perspectiva crítica, posiciona o papel articulador do teórico belga para a pesquisa em comunicação, considerando que as indústrias culturais contemporâneas já não se estabelecem a partir do simples diagrama que onde produção, circulação e consumo estabelecem convergências. Na contemporaneidade, as mídias digitais estão circunscritas em um tecido social complexo, no qual os intercâmbios de informação têm sido mediados por forças que atuam no cruzamento dos campos cultural, político, econômico e tecnológico. Nas duas últimas décadas, o interesse de interpretar os conglomerados transnacionais de tecnologia conduziu Mattelart a considerar como as programações algorítmicas têm sido exploradas com o intuito de extrair dados em escala de seus usuários. Nesse sentido, acreditando que a leitura de Mattelart, aqui revisitada, oferece possibilidades de reflexão sobre a condição dos processos midiáticos, o artigo apresenta subsídios para uma crítica do contrato social que é imposto pelas empresas de tecnologia que circundam o capitalismo de vigilância.

Authors: Karuma Cliff Mirirai , Ngwenya Sizakele Pride , Shangase Sindisiwe
Published: October 2021

Focal reactive gingival lesions are elicited by chronic irritation primarily due to dental plaque, calculus, overhanging dental restorations and ill-fitting dental prosthesis. Persistent irritation of the gingiva can lead to tissue injury and trigger inflammation leading to proliferation of endothelial cells, multi-nucleated giant cells, fibroblasts and tissue mineralisation. The aim and objectives of the study were to determine the relative frequency and distribution of focal reactive gingival lesions according to sex, age, and anatomical site in patients who presented at the Witwatersrand Oral Health Centre. Retrospective cross-sectional study Methods Convenience sampling of patient records from the years 2011 to 2017 were analysed from the Department of Oral Pathology and the Department of Oral Medicine and Periodontology at the Witwatersrand Oral Health Centre. Sociodemographic variables and clinical features were evaluated. Female patients accounted for 70.8% (n = 172) of all focal reactive gingival lesions, with the majority of the lesions having occurred in the maxilla (56.4%; n = 137). The age of patients ranged from 3 months to 88 years. Contrary to findings in other studies, the peripheral ossifying fibroma was the most common focal reactive gingival lesion, after analysing 243 cases
Impact of noise pollution during the COVID-19 pandemic in a hospital area in Sorocaba city, São Paulo State, Brazil
Authors: Andrade Erik de Lima , Lima Eligelcy Augusta de , Zannin Paulo Henrique Trombetta
Published: October 2021

Environmental noise is a public health problem that arises mainly from vehicular traffic. In noise-sensitive areas, such as hospitals, the harm is even greater, as noise affects the recovery of patients and causes stress and disturbance to employees. Noise control measures are usually restricted to simulations and mathematical modeling. Given this context, the present study assesses environmental noise around a public hospital in Sorocaba city, São Paulo State, Brazil, before and during the COVID-19 pandemic, benefiting from measures to restrict the circulation of vehicles and people. Measurements were performed in triplicate, on weekdays, at four points around the hospital during the day, and followed the guidelines of standard NBR 10.151/2019. The number of light and heavy vehicles was counted manually. The equipment used was the BK 2260 analyzer and a tripod with adjustable height. The circulation of light and heavy vehicles decreased significantly during the pandemic. However, this decrease was not enough for sound levels to meet the 50 dB(A) recommended for noise-sensitive areas. This fact can be due to the speed of the remaining vehicles being above the established for the surrounding streets. Vehicles are the main responsible for the high levels of noise in the area, overlapping the levels generated by the different activities in the study site.
FEATURES OF THE APPLICATION OF BUSINESS MODELS IN THE CONDITIONS OF DIGITALIZATION OF ECONOMIC RELATIONS
Authors:   Siberian Federal University, Ananina Rimma
Published: October 2021

The variety of models of conducting economic relations in the last few decades has led to the fact that the most pronounced manifestation and action of those whose competitive foundations allow them to hold current positions or occupy new niches occurs in the market of goods and services. In the article, the author attempts to analyze and compare the characteristics of several models of economic relations: breakthrough innovations, business ecosystems. The model of breakthrough innovations was introduced into scientific circulation by K. Christensen, which is based on changes in values in any market [21]. As noted in the report of the Bank of Russia, in the second quarter of 2021, the market is developing due to the digitalization of the consumer segment and the activity of large online companies [15]. This trend is formed due to the transition of part of economic relations to the real-time mode using digital formats for their implementation, which are based on a certain concept of carrying out activities. In this regard, the study of various business models becomes relevant with the help of an integrated approach that takes into account the diverse development of economic relations.

At the first stage, the experts evaluated the labeling and appearance of the products (manufacturing quality, uniformity of distribution and migration of filler). At the second stage, the species and raw material composition of materials, safety, functionality (water repellency, thermal resistance of the package of materials), reliability (color resistance to various influences, resistance to light and moisture, breaking load of materials) were investigated in the accredited laboratory of the testing center of the Krasnoyarsk CSM. The results of the study showed that despite the presence of labeling violations, all test samples comply with regulated safety requirements and indicators responsible for functional properties. It is concluded that there are no harmonized Russian testing methods and accredited laboratories for down and products with this type of filler. Recommendations are given on the feasibility of developing a comprehensive program for the study of the quality and safety of clothing with feather filler, including the study of filler, testing of textile materials and accessories, testing of finished products for functionality, reliability, ergonomics, taking into account the scope and operating conditions.

Günümüzde iletişim ile ilgili her yapının değişime uğradığı görülmektedir. Dijital iletişim teknolojilerinin önlenemez hızda yükselişi, dijital kimliklerin yaygınlaşması ve pandemi ile birlikte online iletişimde yaşanan artışın bireylerin günlük yaşam aktivitelerinden çalışma biçimlerine, benlik sunumlarından izlenim yönetimi süreçlerine kadar birçok alanı kapsadığına inanılmaktadır. 21.yy’ın ortalarında ve gelecekte toplumumuzun daha yapay zekâya dayalı, büyük veri odaklı ve birbirine bağlı bir dünyada olacağı, sosyal sistemlerin blockchain (blokzinciri) tabanlı bağlantılar ve dağılmış veri tabanlarının bilgi alt yapısında vurgulanacağı belirtilmiştir. Bu makalenin amacı dijital kimlikler ve online iletişim teknolojileriyle yaşanan değişim ve dönüşüm süreçlerini, dijital kimliklerin ve yeni iletişim teknolojilerinin insanların hayatındaki konumunu, benlik sunumlarını Goffman’ın benlik sunumu kuramı bağlamında The Circle (Çember) filminden örnekler ile ortaya koymaktır. The Circle filmi sahneleri ile dijital kimlik ve yeni iletişim teknolojilerinin insan hayatındaki değişim süreçleri örneklendirilmiştir. Sonuç olarak, The Circle filmi analiz edildiğinde Goffman’ın performans, vitrin, takımlar, bölgeler ve bölgesel davranışlar, ayrıksı rollerden muhbir, gözcü ve profesyonel müşteri rolleri, karakter dışı iletişim, izlenim denetimi sanatı kavramlarına ilişkin örnekler bulunmuştur. Bu makalenin dijital kimlik, dijital iletişim, izlenim yönetimi, benlik sunumları konularında yapılacak çalışmalara katkı sunacağına inanılmaktadır.

The papers describes results of theoretical within activity approach analysis and experimental moni¬toring research of developed in educational institutions abilities. Authors propose theoretical conclusions that ability is determined by the individual acquisition of the ukturl way of action in joint activity when solving an educational problem. But at the same time ability is not identical with the revealed and recon¬structed way of action on that it is based. It is the abilities under formation that are being mastered by the student in the educational process represent one of the leading mechanisms, the protagonists of the development of human subjectivity. The papers presents results the monitoring diagnostics of the ability to understand in different age groups of schoolchildren. Diagnostics of the ability to understand was consid¬ered on the basis of students mastering 6 different methods and techniques of understanding. Authors claim сomplex activity diagnostics of the development of understanding, along with diagnostics of other abilities (reflection, theoretical thinking, mutual understanding, goal-setting, self-determination, etc.) makes it pos¬sible to assess the quality of national education.
Collective Imagining: The Early Genesis and Development of a sense of Collectiveness during Infancy
Authors: Fragkiadaki G. , Fleer M. , Rai P.
Published: October 2021

On entering formal education, infants face the demand of participating in collective educational rou¬tines and learning experiences. However, in this age period, the sense of collectiveness is still in an embry¬onic form. This study explored how infants enter into and experience the need for collectiveness and how teachers create the conditions for the development of a sense of collectiveness during infancy. Our educa¬tional experiment drew on a Conceptual PlayWorld, as a collective model of practice for the development of play and imagination. Thirteen infants (0,5—2 years old) participated in the study. Visual methods were used for digital data collection and analysis. It was found that, being in the imaginary situation as play part¬ners, teachers introduced to the infants’ environment the demand to align with the collective, consistently facilitated and sustained infants’ motive orientation to the collective. The use of props, the embodiment of the experience and the shift from physical objects and concrete spaces to a shared intellectual and abstract space appeared to be critical. The findings inform everyday practice and policy opening up a new area of understanding about the concept of collective imagining, as an important concept for the development of a collective orientation for infants.

A pilot cross-sectional online study attempts to clarify the role of implicit sociocultural attitudes in future thinking and tests a hypothesis that the implicit activation of Individualism / Collectivism concepts changes the content and other characteristics of self-relevant images of the future — self-defining future projections (SDFPs). The study performed in 2019-2020 involved 191 people, mean age — M = 36.9 (SD = 10.4) years. Group 1 underwent Individualism priming: 108 people (11.2% of males), mean age — M = 37.6 (SD = 1.04) years. Group 2 underwent Collectivism priming: 83 people (22.9% of males), age — M = 36 years (SD = 1.13). No significant sociodemographic between-group differences were found (p<0.05). Two versions of the online survey (one with an Individualism priming task and another with a Collectivism priming task) were randomly sent to students and teachers of Russian higher education institutions. After completing the priming task, the respondents constructed SDFPs in line with the definition provided and evaluated their quality. Experts rated SDFP thematic content, integration of meaning and specificity in accordance with valid coding pro¬cedures. Collectivism / Individualism levels were assessed using the INDCOL test. The priming procedure had a small significant effect on SDFP thematic content, interpersonal orientation, and specificity. It was more prominent in the Collectivism priming, although expected correlations between the Individualism and feelings of the Autonomy and Competence need satisfaction in SDFPs were also found. Collectivism seemed to strengthen future thinking overgenerality and to hinder the capacity to reflect on one’s own future. On the contrary, Individualism involves taking personal responsibility, but it seemed to enhance the need for Relatedness and social support (a protective factor in depressive conditions) in a compensatory manner. The data contributes to a further understanding of implicit influences on future thinking and suggest that it is the balance of the Collectivism and Individualism values that is crucial for mental health.

The 2019–2020 Southwest Puerto Rico Earthquake Sequence: Seismicity and Faulting

Published: October 2021

The 2019–2020 Southwest Puerto Rico earthquake sequence ruptured multiple faults with several moderate magnitude earthquakes. Here, we investigate the seismotectonics of this fault system using high-precision hypocenter relocation and inversion of the near-field strong motions of the five largest events in the sequence (5.6≤Mw≤6.4) for kinematic rupture models. The Mw 6.4 mainshock occurred on a northeast-striking, southeast-dipping normal fault. The rupture nucleated offshore ∼15 km southeast of Indios at the depth of 8.6 km and extended southwest–northeast and up-dip with an average speed of 1.55 km/s, reaching the seafloor and shoreline after about 8 s. The 6 January 2020 (10:32:23) Mw 5.7 and the 7 January 2020 (11:18:46) Mw 5.8 events occurred on two east–southeast-striking, near-vertical, left-lateral strike-slip faults. However, the 7 January 2020 (08:34:05) Mw 5.6 normal-faulting aftershock, which occurred only 10 min after the Mw 6.4 normal-faulting mainshock, ruptured on a fault with almost the same strike as the mainshock but situated ∼8 km farther east, forming a set of parallel faults in the fault system. On 11 January 2020, an Mw 6.0 earthquake occurred on a north–northeast-striking, westing-dipping fault, orthogonal to the faults hosting the strike-slip earthquakes. We apply template matching for the detection of missed, small-magnitude earthquakes to study the spatial evolution of the main part of the sequence. Using the template-matching results along with Global Positioning System analysis, we image the temporal evolution of a foreshock sequence (Caja swarm). We propose that the swarm and the main sequence were a response to a tectonic transient that most affected the whole Puerto Rico Island.
