The Allometry of Morphology in Flora and Fauna of New Zealand and Offshore Islands
Authors: Woodhams Carl
Published: April 2021

Flight is the primary form of locomotion for many avian species and is enabled by allometric scaling of morphological features such as wingspan, flight muscle size, and bone tensile strength. Contrary to this, the evolution of flightlessness in birds displays a selection towards an increase in body size with a reduction in flight associated features. The aim of this chapter is to explore the Loss of Dispersibility hypothesis as a cause for flightlessness in island birds, with consideration of the Island Rule and the Size-Constraint hypothesis. With island species paired with closest mainland relatives, comparative analyses were conducted comparing the change in wing loading ratios, wing lengths, and mass. With paired t-tests and Major Axis linear regression modelling, the hypotheses of isometric or allometric scaling in each of the features were tested. An increase in wing-loading ratio was apparent for many island species, as well as an increase in both mass and wing length. However, the rate of increase between mass and wing length is disproportionate, with mass increasing at a greater rate than wing length. These trends reject the Loss of Dispersibility hypothesis in support of the Size-Constraint hypothesis while providing little evidence for the Island Rule.

Authors: Baek Jae-Seung , Kim Sungkyu , Yoem Myeonghoon
Published: April 2021

The unprecedented COVID-19 pandemic at the beginning of 2020 jeopardized the entire world. Meanwhile, the Russia–Saudi Arabia oil war led a crude oil market going out of the frying pan into the fire. This research has two main purposes. First, we investigate structures of the crude oil related exchange-traded products (ETPs) in terms of operation and cost. Second, we analyze the correlation and investment performance of the crude oil related ETPs and West Texas Intermediate spot market. The major findings are as follows: (1) there is a positive correlation between the crude oil spot and the crude oil producing firm, (2) the investment performance of the crude oil related ETPs is inferior to that of the crude oil spot due to the rollover cost, (3) the investment performance of the crude oil related leverage ETNs (Exchange-Traded Notes) or inverse ETPs has deteriorated because their managing structure tracks the daily return which leads to the compounding effects. These empirical results show the characteristics of the gain and loss of the crude oil-related ETPs, which enhance conceptual understanding and offer implications to policymakers and authorities for the efficiency of the alternative investment strategy.

Published: April 2021

Existen problemáticas ambientales, de deforestación por avance de la frontera agrícola, uso de plaguicidas, compactación y erosión del suelo, entre otros, sobre la Cordillera de los Andes, que se convierten en factores determinantes en la configuración de los paisajes y del territorio, este último entendido como el lugar donde se evidencian no solo los aspectos biofísicos, sino principalmente los culturales, que en definitiva determinan la forma en cómo se trabaja el suelo, se producen los alimentos y se gestan las relaciones sociales que configuran los actuales paisajes de la cordillera de los Andes. La cuenca alta del río Sábalo, ubicada en la parroquia de Valle Hermoso, provincia de Santo Domingo de los Tsáchilas no escapa a esta realidad andina, caracterizada su problemática ambiental principalmente por el avance de la frontera agrícola, la deforestación en áreas sensibles como nacimientos de agua, y en las riberas de los esteros Lolita y Roncador que al unir sus aguas a la altura del km 3 conforman el río Sábalo. Uno de los indicadores que se usaron en la presente investigación como reflejo de esta problemática es la contaminación de materia orgánica (DQO), la cual se incrementa aguas abajo 10,7 mg L-1 en relación con la parte alta de la cuenca que corresponde a 2,44 mg L-1. Se encontró que el caudal de los cuerpos de agua en época seca  desaparece o disminuye a niveles que no alcanzan a cumplir con las condiciones de caudal ecológico. En cuanto a los parámetros microbiológicos especialmente Coliformes Fecales (CF) el agua en la zona de captación del río Sábalo (Parte baja de la cuenca) no cumple con lo establecido en la Tabla 3 del TULSMA.

High Scalability Document Clustering Algorithm Based On Top-K Weighted Closed Frequent Itemsets
Authors: Pradnyana Gede Aditra , Djunaidy Arif
Published: April 2021

Documents clustering based on frequent itemsets can be regarded a new method of documents clustering which is aimed to overcome curse of dimensionality of items produced by documents being clustered. The Maximum Capturing (MC) technique is an algorithm of documents clustering based on frequent itemsets that is capable of producing a better clustering quality in compared to other similar algorithms. However, since the maximum capturing technique employed frequent itemsets, it still suffers from such several weaknesses as the emergence of items redundancy that may still cause curse of dimensionality, difficult to determine the minimum support value from a set of documents to be clustered, and no weighting on items incurred to the resulting frequent itemsets.  To cope with those various weaknesses, in this research, an algorithm of documents clustering based on weighted top-k closed frequent itemsets, which is called as Weighted Maximum Capturing (WMC) algorithm, is developed. The proposed algorithm involves the frequent pattern tree algorithm to mine closed frequent itemsets from a set of documents without specifying the minimum support value of items to be generated.  Experimental results showed that improvement on the resulting clustering accuracy was produced. The resulting average values of F-measure of 0.713 and purity of 0.721 with improvement ratio of 1.4% for F-measure and 2% for purity.  Nevertheless, results of the scalability test showed very significant improvement.  The WMC algorithm only requires the average computing time of 623.77 minutes, 518.05 minutes faster than the average computing time required by the MC algorithm.

The current agricultural systems generally uses chemical fertilizers as a growth booster in order to meet the global food needs of 7 billion people and all of their livestock. But unfortunately not all are aware of the great danger behind such an overuse, unmetered application of chemical fertilizers, freely in an open field for the survival of the planet and its population. Thanks to technological advances, especially in the field of instrumentation and communication technology, the problem of increasing efficiency and avoiding such overuse should be minimized properly. In this study, the researchers tried to apply capacitive moisture sensor technology and serverless Internet of Things to the moisture meter instrument in the hydroponic drip fertigation system with roasted husk planting media. Capactive sensor technology has the advantage of corrosion resistance when applied to planting media containing high humidity and low alkalinity. By using a serverless IoT architecture, it is possible to monitor from anywhere via the internet, without involving complicated and expensive infrastructure. Based on the results of the prototype testing, it is known that the instruments built can work properly. The results of monitoring system conditions such as temperature and free heap appear stable. The reading results of the two sensors also run steadily, without fluctuations and variations in the reading that exceed 5%. The process of remote monitoring and data logging to serverless IoT is monitored to be stable with a data recording success rate of 99.8%.

TRANSMEDIA STORYTELLING AS A WAY TO TURN FAN PRACTICES INTO A CULTURAL INDUSTRY
Authors:   HSE University, MILOVIDOV STANISLAV V.
Published: April 2021

There are numerous empirical sociological researches of transmedia storytelling media consumption. However, they mainly record either the practices of media consumption of specific media formats included in the structure of a transmedia project or the producers’ ways for constructing a narrative that creates transitions between media platforms. Often, researchers pay little attention to the circumstances of users’ interaction with the fictional world and their social relationships that form around a transmedia project. This study consists of a series of in-depth interviews and observations on the media consumption practices of users and fans of the fictional world which has formed around a series of fantasy works under the general name The Witcher. This transmedia project is interesting because, unlike specially created transmedia franchises with the expansion structures carefully planned by media companies, it forms itself spontaneously, as a result of the activities of different institutions and user participation, does not have a single development strategy, and is shaped by “grass-root” practices. The observation of media consumption practices of transmedia storytelling allows us to conceptualize construction’s НАУКА ТЕЛЕВИДЕНИЯ № 17.1, 2021 31 THE ART AND SCIENCE OF TELEVISION peculiarities, such as narrative structures. Based on this data, it is possible to construct a network of interactions formed by the user migration between media platforms and compare such practices with the audience’s everyday practices. Since modern people form their understanding of the world based on their own experience and by using mediatized communication, transmedia storytelling represents a special kind of virtual reality or its particular case, which can be supplemented with the help of VR-technologies.
THE FIRST SCREENING OF ALICE IN WONDERLAND (1903)
Authors:   State Institute for Art Studies, SALNIKOVA EKATERINA V.
Published: April 2021

The article is dedicated to the British silent film Alice in Wonderland by Percy Stow and Cecil Hepworth, which was found and restored in 2010. The 12-minute film was unusually long for early cinema. Almost all of the survived credits annotate several short scenes at once, showing their interconnection or, conversely, apartness from each other. This suggests that some scenes were sold not separately, but as a series of scenes united by a credit. Structurally, each fragment of the film, consisting of 2–3 scenes, is similar to one episode of series. Therefore, the origin of the principles of seriality in cinema can be associated with film adaptations of fairy-tale stories. The concept of space demonstrates the inner duality of the Wonderland. The private part of it looks like an English landscape garden, while the space of the Queen and her entourage is designed as a classicist regular park. In his adaptation (2010) of Carroll’s fairy-tale, Tim Burton will further unfold the theme of duality and conflict inside the Wonderland. In the 1903 film adaptation, Alice was played by May Clark, a grown-up girl who worked at the Hepworth studio. The dreamlike nature of the screen reality is emphasized by the restraint of the amateur performers’ play and the unobtrusiveness of the fantastic, when the screen fantasy world is both similar and different from the everyday life. The marriageable age of the heroine and some of the scenes that look like Alice’s “going through the torments” make us interpret the action as the embodiment of her unconscious. The magic garden, where a young girl is so eager to get, a symbol of the desirable joys of an adult life, becomes a nightmare for Alice. The film was released in the same year as the Women’s Social and Political Union (WSPU) was established, and it merged into an era of revision of Victorian ideals and rejection of the perception of women in line with patriarchal values. Tim Burton’s film, created in the era of the new emancipation and reconsideration of gender, largely corresponds to the first screen adaptation of Alice in Wonderland, presenting the Victorian world as a generalized image of a society that suppresses the individual and naturally provokes protest.

Objective Excessive internet use has been associated with various psychiatric symptoms and psychosocial factors. This study aimed to investigate the prevalence of internet addiction (IA) and its associations with clinical (depression/social anxiety) and psychosocial (self-esteem/perceived social support) factors in medical students.Methods In total, 408 medical students at one university in Korea were included in this study. IA symptoms were assessed with Young’s Internet Addiction Test, and scores of 50 or higher were considered to indicate IA. Participants were asked to complete the Beck Depression Inventory, Social Phobia Inventory, Rosenberg Self-Esteem Scale, and Duke-University of North Carolina Functional Social Support Questionnaire. A logistic regression model was constructed to examine the impact of clinical and psychosocial factors on IA.Results Forty-seven participants (11.5%) were identified as having IA. Self-esteem was associated with a lower risk of IA, whereas depression and social anxiety were associated with a higher risk of IA. Depression, social anxiety, low self-esteem, and low perceived social support were found to be significant correlates of IA. Young’s Internet Addiction Test score positively correlated with Beck Depression Inventory and Social Phobia Inventory scores, but negatively correlated with Rosenberg Self-Esteem Scale and Duke-University of North Carolina Functional Social Support Questionnaire scores. Furthermore, the prevalence of IA was highest in first-year medical students.Conclusion This study revealed the possible risk and protective factors of IA. Our findings indicate that strengthening self-esteem and reducing depression and social anxiety may contribute to the prevention and management of IA in medical students.

Установлено, что в Российской Федерации требования к материалам полимерной упаковки для лекарственных средств приведены в таких стандартах качества, как ГОСТ, ОСТ, ТУ, тогда как за рубежом они включены в фармакопеи, при этом методики испытаний и требования могут различаться, что вызывает необходимость включения в Государственную фармакопею РФ ОФС, регламентирующих требования к полимерным материалам и упаковке на их основе. Показано, что риски применения полимерной упаковки в значительной мере зависят от условий стерилизации и взаимодействия лекарственного препарата с материалом упаковки при хранении. Даны рекомендации по проверке совместимости содержимого контейнера с материалом полимерной упаковки, описана стратегия выбора полимерного материала, используемого для первичной упаковки лекарственного препарата, при фармацевтической разработке лекарственного препарата и технологии его производства.
