Physical Features

With the growth of online commerce, companies have created virtual communities (VCs) where users can create posts and reply to posts about the company’s products. VCs can be represented as networks, with users as nodes and relationships between users as edges. Information propagates through edges. In VC studies, it is important to know how the number of topics concerning the product grows over time and what network features make a user more influential than others in the information-spreading process. The existing literature has not provided a quantitative method with which to determine key points during the topic emergence process. Also, few researchers have considered the link between multilayer physical features and the nodes’ spreading influence. In this paper, we present two new ideas to enrich network theory as applied to VCs: a novel application of an adjusted coefficient of determination to topic growth and an adjustment to the Jaccard coefficient to measure the connection between two users. A two-layer network model was first used to study the spread of topics through a VC. A random forest method was then applied to rank various factors that might determine an individual user’s importance in topic spreading through a VC. Our research provides insightful ways for enterprises to mine information from VCs.

The spiritual dimensions of the road accompanied a person not only in the pre-Gutenberg (oral communication) but also in the post-Gutenberg era. Its mythological manifestations are still relevant today, when communication dominates the Internet space. The research topic is conditioned by this topic. The article presents a mythological image of a road, a number of components of which are woven into the structural and semantical layers of modern media texts. The purpose of the article is to highlight important aspects of this phenomenon based on an analysis of the cultural and political texts of modern Armenian media. In the process of research, we used content and discourse analyses. About thirty publications were selected from different websitesin which through discourse analysis, the substantive features of the mythologeme of the road in Armenian media texts were revealed.His formulation of the problem presupposed the initial presentation of a number of general attributes of the road mythologeme (sacred structure, the road as a “meeting place” of space and time, the presence of horizontal and vertical planes in mythological ideas about the road, the soul’s journey into the inner consciousness and into the world of one’s own “I” , etc. on the basis of which the analysis of cultural and political publications on Armenian websites was made. The research topic is promising, since in its interdisciplinary context it can suggest new ideas not only to media researchers but also to specialists in cultural studies, philosophy, and psychology.In publications on cultural themes, the mythologeme is expensive and enriches the dynamic picture of Armenian cultural life contributing through its spatial-temporal perspective and the author’s inner “I” to the national self-knowledge of the audience. In political publications, where “the road of Thought” is paramount, the culture of internal polemics, the search for the continuation of the key points of the mental road play an important role. The author’s word is transmitted to the reader with the division of time at certain intervals. Thanks to these important criteria, the spiritual and mental picture of the road asserts its distinctive presence in the Armenian media space.

Long Run

The Russian economy heavily relies on exports of its natural resources. However, the resource-based status quo does not seem to be the route towards Russia’s long-run prosperity. To improve its position in the global income ranking, Russia needs to diversify its exports and make them more complex. Using highly detailed data on trade flows and applying network theory apparatus, we evaluate the level of export complexity in Russia from 1995 to 2016 and compare it with that of its BRICS fellow members. We find that Russia is stagnant with respects to its relative level of export complexity. This sluggishness embraced the entire period between 1995 and 2016, much longer than the stage of anemic growth that started there a decade ago. We also conclude that the current stock of know-how in Russia is relatively low and fragmented, thus not letting Russia diversify into a broad range of more complex products. Russia might also need to export a wider variety of products to richer economies. Today, on a par with Brazil and South Africa, it supplies a broader range of goods to its slowly growing next-door neighbors.

The scope of this research is the application of the random forest method to SPOT 7 data to produce bathymetry information for shallow waters in Indonesia. The study aimed to analyze the effect of base objects in shallow marine habitats on estimating bathymetry from SPOT 7 satellite imagery. SPOT 7 satellite imagery of the shallow sea waters of Gili Matra, West Nusa Tenggara Province was used in this research. The estimation of bathymetry was carried out using two in-situ depth-data modifications, in the form of a random forest algorithm used both without and with benthic habitats (coral reefs, seagrass, macroalgae, and substrates). For bathymetry estimation from SPOT 7 data, the first modification (without benthic habitats) resulted in a 90.2% coefficient of determination (R2) and 1.57 RMSE, while the second modification (with benthic habitats) resulted in an 85.3% coefficient of determination (R2) and 2.48 RMSE. This research showed that the first modification achieved slightly better results than the second modification; thus, the benthic habitat did not significantly influence bathymetry estimation from SPOT 7 imagery.

The Impact

The aim of this article is to analyse the impact of COVID-19 on the income models of the Spanish general inter­est press through an in-depth analysis of the case of ‘El Mundo’. This article shows data about the decline in adver­tising, both in printed and digital for­mats, during the first quarter of 2020 and, more specifically, during March. It also reveals that the media platforms with a previously implemented sub­scription system have gained a signif­icant number of new registrations. Not only is ‘El Mundo’ an example of this trend, but also other newspapers such as ‘Eldiario.es’, ‘Ara’, ‘La Razón’ or ‘La Voz de Galicia’. The reader becomes an alternative to lessen advertising losses at a time of global transformation of the industry towards reader-revenue models. Long-term consequences of a probable economic recession once the pandemic effects are reduced are also considered in the analysis. The article also outlines some key points to ensure the viability of newspaper publishers, such as investing in journalists with relevant sources or profiles that know how to manage new digital businesses. Keywords: COVID-19, press, business, subscriptions and advertising.

College education institutions regularly hold new student admissions activities, and the number of new students can increase and can also decrease. University of PGRI Semarang (UPGRIS) on the development of new student admissions for the 2014/2015 academic year up to 2018/2019 with so many admissions selection stages. To meet the minimum comparison requirements between the number of students with the development of human resources, facilities, and infrastructure, it is necessary to predict how much the number of students increases each year. To make a prediction system or forecasting, the number of prospective new students required a good forecasting method and sufficiently precise calculations to predict the number of prospective students who register. In this study, the method to be taken is the Random Forest method. For the evaluation of forecasting models used Random Sampling and Cross-validation. The parameter used is Mean Absolute Error (MAE), Mean Squared Error (MSE), Root Mean Squared Error (RMSE), and Coefficient of Determination (R2). The results of this study obtained the five highest and lowest study programs in the admission of new students. Therefore, UPGRIS will make a new strategy for the five lowest study programs so that the desired number of new students is achieved

Living Tissues

Tissues change in many ways in the period that they are part of a living organism. They are created in fairly repeatable structural patterns, and we know that the patterns are due to both the genes and the (mechanical) environment, but we do not know exactly what part or percentage of a particular pattern to consider the genes, or the environment, responsible for. We do not know much about the beginning of tissue construction (morphogenesis) and we do not know the methods of tissue construction. When the tissue structure is altered to accommodate a new loading, we do not know how the decision is made for the structural reconstruction. We do know that tissues grow or reconstruct themselves without ceasing to continue with their structural function, but we do not understand the processes that permit them to accomplish this. Tissues change their structures to altered mechanical environments, but we are not sure how. Tissues heal themselves and we understand little of the structural mechanics of the process. With the objective of describing the interesting unsolved mechanics problems associated with these biological processes, some aspects of the formation, growth, and adaptation of living tissues are reviewed. The emphasis is on ideas and models. Beyond the objective is the hope that the work will stimulate new ideas and new observations in the mechanical and chemical aspects of developmental biology.

Drafting and designing in architecture involve an iterative process of testing and comparing architectural thoughts and ideas. The goal of this iterative process is to find the best of several possible solutions, at each stage of the design process. To bring these architectural thoughts and ideas to reality designers need tools. Tools for discussing ideas and writing, sketching, plan drawing and model making for explaining, documenting and testing thoughts. But do the users of these tools, the designers, really know how these tools work or do the designers use these tools only out of habit? Some tools are already known for how they transport ideas, other tools are used out of behaviour without understanding their deeper impact on transporting thoughts and generating new ideas.

Physical Features

In this study, eight different shells from different species were examined by looking at the physical features of the shells. The purpose of the study was to identify evolutionary links between species with shells. From these physical features, a morphological phylogeny was compiled. And from the morphological phylogeny, it was shown that their the family of the shells was the first trait defined specific clades and that each synapomorphic trait after this was a physical feature of the shells. From the experiment, the following conclusions were discovered: 1) That Scallops and Cockles are the most morphologic clay similar. 2) For taxa A, trait III is an apomorphy because this trait is a single trait that defines this taxa separately from the other taxa. 3) For taxa A, trait I is a plesiomorphy because it is a trait that is ancestral to trait III which defines taxa A (Fig. 2). From the data, these conclusions could introduce a new topic, new ideas, and new information to existing researches.The influx of new ideas would either become helpful, or build off the research of other researchers. This would help the scientific community in increasing its knowledge of the evolutionary background of more species.
