Color difference evaluation for wide-color-gamut displays
Authors: Zhao Baiyue , Xu Qiang , Luo Ming Ronnier
Published: July 2020

With the emerging demand for wide-color-gamut displays, an issue has been raised in which the commonly used color difference formulae or uniform color spaces that were derived based on the data produced in the relatively smaller color gamut could be unreliable for predicting color differences in the highly saturated color regions. A psychophysical experiment was carried out for evaluating color difference at a luminance level of310cd/m2on a wide-color-gamut display with an approximate DCI-P3 color gamut. Twelve color centers were selected to cover the entire gamut boundary. There were 192 pairs of samples over 12 color centers judged by 18 observers using the greyscale psychophysical method. The data set was used to test the performance of six uniform color spaces and color difference equations, CIELAB, CIEDE2000, CAM02-UCS,Jzazbz,ICTCP, andnICTCP, a newly revisedICTCPformula. The color discrimination ellipses were used to test local and global uniformity of color spaces and compared with previous studies. The results revealed that all formulae improved their performance to have a mean lightness parametric factor of about 0.5. CAM02-UCS significantly outperformed the others in overall, local, and global uniformity. The high-quality visual data set is recommended to evaluate or to derive color difference formulae for WCG applications in the future.
User-specific power level allocation optimization for OFDM-NOMA in a multi-user RoF system
Authors: Shi Jin , Chen You-Wei , He Jing , Zhou Zhihua , Yan Xinda , Shiu Run-Kai , Chang Gee-Kung
Published: July 2020

In this Letter, we propose a digital signal processing (DSP) -aided technique to optimize the power ratio among users for orthogonal frequency division multiplexing (OFDM) -based non-orthogonal multiple access (NOMA) in an integrated optical fiber and millimeter wave (mmWave) wireless communication system. In this way, a central or distributed unit can leverage the proposed techniques to maintain the uniformity of the signal-to-noise ratios (SNRs) among subcarriers without requiring any channel information feedback. The proposed mechanism can facilitate the power allocation management by treating all subcarriers equally as an independent channel. As an illustration, multiple NOMA scenarios, in which a near user with 10 km fiber transmission and far user with either longer fiber distance or additional wireless propagation, are experimentally investigated. Experimental results demonstrate that when the conventional OFDM-NOMA without the proposed DSP-aided technique is used, the optimal power ratios vary rapidly when the subcarrier quality index changes due to high-frequency fading in a mmWave radio over fiber (RoF) system, whereas, by using the proposed techniques, including both orthogonal circulant matrix transform and discrete Fourier transform, the optimal power ratios on all effective subcarriers are optimized at the same level and the users’ performance is significantly improved.
Optical levitation using broadband light
Authors: Rahman A. T. M. Anishur , Barker P. F.
Published: July 2020

The ability to create dynamic, tailored optical potentials has become important across fields ranging from biology to quantum science. We demonstrate a method for the creation of arbitrary optical tweezer potentials using the broadband spectral profile of a superluminescent diode combined with the chromatic aberration of a lens. A tunable filter, typically used for ultrafast laser pulse shaping, allows us to manipulate the broad spectral profile and therefore the optical tweezer potentials formed by focusing of this light. We characterize these potentials by measuring the Brownian motion of levitated nanoparticles in vacuum and also demonstrate interferometric detection and feedback cooling of the particle’s motion. This simple and cost-effective technique will enable wide application and allow rapid modulation of the optical potential landscape in excess of megahertz frequencies.
Costume in the dance archive: Towards a records-centred ethics of care
Authors: von Rosen Astrid
Published: July 2020

Focusing on the archival records of the production and performance of Dance in Trees and Church by the Swedish independent dance group Rubicon, this article conceptualizes a records-oriented costume ethics. Theorizations of costume as a co-creative agent of performance are brought into the dance archive to highlight the productivity of paying attention to costume in the making of performance history. Addressing recent developments within archival studies, a feminist ethics of care and radical empathy is employed, which is the capability to empathically engage with others, even if it can be difficult, as a means of exploring how a records-centred costume ethics can be conceptualized for the dance archive. The exploration resulted in two ethical stances useful for better attending to costume-bodies in the dance archive: (1) caring for costume-body relations in the dance archive means that a conventional, so-called static understanding of records as neutral carriers of facts is replaced by a more inclusive, expanding and infinite process. By moving across time and space, and with a caring attitude finding and exploring fragments from various, sometimes contradictory production processes, one can help scattered and poorly represented dance and costume histories to emerge and contribute to the formation of identity and memory. (2) The use of bodily empathy with records can respectfully bring together the understanding of costume in performance as inseparable from the performer’s body with dance as an art form that explicitly uses the dancing costume-body as an expressive tool. It is argued that bodily empathy with records in the dance archive helps one access bodily holisms that create possibilities for exploring the potential of art to critically expose and render strange ideological systems and normativities.
Celebrating Bowery: Radical costume parties as queer heterotopia in Brisbane
Authors: Taylor Madeline , Hickey Anna Germaine , Roehrs Remi
Published: July 2020

This visual essay explores the creative practice of The Stitchery Collective, which uses costume as a strategy in their participatory works. Inspired by performance artist, queer icon and costume lover Leigh Bowery, The Stitchery Collective has created The Bowery Party, a series of events encouraging radical dress up. These immersive occasions emphasize the significance of costume as enabling joy, community and extravagant social performance. The essay discusses the importance of Bowery as a figure in designing the party in terms of the nature of participant responses, as his legacy provides a subversive approach to costuming the self. The analysis focuses on strategies for and the importance of making and holding space, both physical and virtual, for alternate visions of the body – an empowering ethic that celebrates diversity and inclusivity. The costumes created by the attending public are challenging, often both to wear and to social, gender and body norms. This essay offers a brief example of the costumes created by participants in direct response to Bowery as a radical, slippery and chaotic aesthetic target.

typhi as Gram-negative bacterial strains.
Antioxidant Activity of 2-Bromo-3-hydroxy-2-nitroproylcinnamte against Alcohol Induced Oxidative Damage
Authors: Malik Rajesh Kumar , Singh Dharmendra Kumar , Anuradha  , Kumar Surendra
Published: July 2020

The present study demonstrated the antioxidant activity of 2-bromo-3-hydroxy-2-nitroproylcinnamte versus alcohol induced oxidative damage in albino wistar rats. In this study, 30 % alcohol exposed rats were found to be more prone to peroxidative risk as they are calculated by species of thiobarbituric acid. It was observed that after the rats induction with 30% alcohol, concentration of lipid peroxidation has been obtained expressively (p ≤ 0.001) high in a liver and serum, beside with concomitant substantial (p ≤ 0.001) reduced in enzymatic and non-enzymatic antioxidants levels like catalase (CAT), superoxide dismutase (SOD), glutathione reductase (GR), glutathione peroxidase (GPx), vitamin E (tocopherol), reduced glutathione (GSH), glutathione-s-transferase (GST), vitamin C (ascorbic acid), β-carotene as well as ceruloplasmin in serum along with liver, only 30% alcohol was treated. If rats obtained 2- bromo-3-hydroxy-2-nitroproylcinnamte at the dose level of 20 mg/kg bw/day, PO, for 30 days, the peroxidative damage has been marginal in serum along with liver, alongside efficiently encouraging the potential of antioxidant in the rats treated by alcohol. This study revealed that in liver the raised peroxidative risk is probably allied with alcohol induction pathology that can be decreased by increasing the antioxidant potential by free radical scavenging activity, therefore promising as artificial antioxidants for 2-bromo-3-hydroxy-2-nitroproylcinnamte.

Results: As a result of statistical analysis,  although there was no statistical difference between pedodontists and endodontists in their knowledge levels, it was found that both occupational groups had higher knowledge level than general dentists (p = 0,0001). While there was a significant difference between practitioners  at university and oral and dental health hospital (p = 0.0001), there was no difference between practitioners  in university hospital and private office (p = 0.065). Conclusions: In conclusion, general dentists had knowledge of inadequate dental trauma management and the knowledge level of dentists working at oral and dental hospital  was lower.KeywordsDental Trauma; Knowledge Level; General Dentist; Endodontists; Pediatric Dentistry.
Implementing High Energy Liquid Nutrition, Omega-3 Fatty Acids and Nutritional Supplements for the Treatment of Anorexia Nervosa
Authors: Baumann Christoph , Willaschek Christian , Kertess-Szlaninka Tuende , Johanna Lang , Buchhorn Reiner
Published: July 2020

Objective:
To assess the effect of different treatment approaches on the course of anorexia nervosa (AN) over time.

Methods:
The subjects were 27 hospitalized AN patients. In our retrospective analysis we compared weight gain in two groups. While one group was treated with a standard oral refeeding protocol (historical control) through January 2013 (N=16), the second group (highly standardized refeeding protocol) received a high energy liquid nutrition and nutritional supplements including omega-3 fatty acids (N=11).

Results:
On admission, the two groups were comparable in terms of height, weight, age and heart rate. At the end of our monitoring time frame of 25 days, weight gain was 121.4% higher in the highly standardized refeeding protocol group than in the historical control group (66.5 ±52.4 vs 147.3 ±55.7 grams/day; t-Test p=0.004; CI95%: 29.3-132.2). A carbohydrate rich diet clearly improved weight gain if high energy liquid nutrition was replaced by the diet according the patient’s own wishes. About 45% of our patients stated they were vegetarians at admission. However, we could not identify a vegetarian diet as a statistically significant negative prognostic factor for weight gain.

Conclusion:
The highly standardized refeeding protocol seems to be helpful in malnourished AN patients to improve weight gain without enhancing the risk of a refeeding syndrome. However, further studies with greater number of patients are needed to confirm the effectiveness of our standardized treatment protocol.
Term Paper on The Nature of Cyber Crime and Cyber Threats: A Criminological Review
Authors: Mozid Ashraful , Yesmen Nelufer
Published: July 2020

Cybercrime is one of the fastest-growing criminal activities in contemporary age. The first recorded cybercrime happened in France in the year 1820. It was not as sophisticated as cybercrime we know in our world today, but, still, that was a crime. Cybercrime has evolved globally as the online platform is progressing. While progress is made in the battle against cybercrime there still remains a wide gap in the consistency of laws across international borders. The main objectives of this study are to explore the nature of cybercrime in developing countries, find out the cyber threats for terrorist activities and explain cybercrime and threats from criminological aspects. This is a descriptive study which is based on secondary data. This study is based on previous researches & studies. this paper discusses the nature of cybercrime in developing countries. It could allow developed countries to understand better the national and international effects of that cyber threats, to determine the conditions of current regional and international agreements, and to help countries create a sound legal framework. And then we notice the impact of cyber threats all over the world. At last, we discuss cybercrime from criminological point of view. Cybercrime is not limited to two neighboring countries and cross-border conflicts; an attempt could be conducted from another world. It is fearful to see cyber wars as the easiest way to carry out sabotaging rather than wars such as cold war, chemical and biological wars, terrorist wars or jihadist attacks. The international legal framework aims by the International Criminal Court to keep offenders accountable for their actions. The government has by far the biggest burden and obstacle in raising knowledge of cybercrime among the people.

It is a process between fuel and oxidants in which heat is generated due to changes in chemical constituents. By releasing heat, it may occur light in the form of annealing or flame. There are accidental and arson fires. This work is dedicated to all firefighters in the world who very often find themselves in situations where they save the lives of others while neglecting their own safety. Firefighters are the heroes of modern times.
Does Digital Terrorism Really Exist?
Authors: Buresh Donald L.
Published: July 2020

This paper attempts to answer the question of whether digital terrorism, also known as cyberterrorism, exists. The paper defines terrorism both in the conventional and digital sense. It then gives a short history of conventional terrorism, dating back two thousand years and ending with the terrorist activities in several third-world nations. The essay then discusses digital terrorism, highlighting the Estonian, Georgian, and Ukrainian cyber-attacks. The work concludes that digital terrorism does indeed exist, but that the future is uncertain in the sense that future cyber-attacks will probably not resemble past attacks as the technology advances.

Published: July 2020

Higher-order thinking skill is closely related to literacy skills. However, data from PIRLS 2011 states that the reading ability of elementary school students in Indonesia is relatively low because it is ranked 42 out of 45 countries. Data from PISA 2018, Indonesia ranked 74 out of 76 countries. Though literacy skill influences mindset. The purpose of this study is to explain: a) the basic concepts of literacy, b) the basic concepts of High Order Thinking Skills, and c) the literacy skill to improve high order thinking skills in elementary school students. The approach used in this study is qualitative. The research method used is content analysis. The data sources are journals and books related to literacy and high order thinking skills. The results of this study are: first, literacy is the ability to interpret information critically and can convey knowledge to others accurately. Second, higher-order thinking skills is the process of thinking students at a higher level of knowledge from various cognitive concepts such as analysis, synthesis, evaluation, and creation. Third, literacy skills improve higher-order thinking. The strategies used by schools include conditioning literacy-friendly physical environments, seeking social and affective situations as literate models of communication and interaction, and striving schools as a literate academic environments.
All Roads Lead to Homosociality: The Role of Chivalry in Medieval and Modern Society
Authors: McDougall Grace Margaret
Published: July 2020

This paper examines the role of chivalry in two of Marie de France’s lais, Guigemar and Bisclavret. One of the most studied authors of the Medieval period, Marie de France’s works reveal the values, anxieties, and societal dynamics of her time by both adhering to and pushing against literary norms. Guigemar and Bisclavret present near-perfect examples of knighthood, save for two flaws: Guigemar has no love for women, and Bisclavret is a werewolf. The treatment of these knights and their peculiarities reveals the strict expectations of masculinity and the risks of breaking from them. I pay particular attention to the importance of humility in chivalric masculinity and the ways in which their peculiarities affect their relationships, particularly with other men. When placed in conversation, these stories show that the main role of chivalry was to secure the relationships between men that formed the basis of Medieval society and that, for this reason, humility was one of the most important chivalric values. I argue that understanding the cultural history of chivalry is important for modern audiences because the concept of chivalry is still used by many groups to legitimize and promote their interests and continues to shape our perceptions of masculinity and gender dynamics. While what we think of chivalry has changed greatly since Marie de France’s time, the ends of chivalry remain the same—to promote the interests of those in positions of power.

Nos proponemos dar cuenta de dichos cambios y del impacto que tuvieron en la construcción y el ejercicio del rol de los inspectores de enseñanza a partir del análisis de fuentes documentales y normativa oficial.
La resolución de problemas desde un enfoque epistemológico
Authors: Díaz Lozada Jorge Antonio , Díaz Caballero José Ricardo
Published: July 2020

La relación del sujeto con el conocimiento es una cuestión esencial en el marco del desarrollo acelerado de la ciencia y la tecnología, razón que ha instituido el aprender a aprender como uno de los pilares de la educación. Las formas de adquisición del conocimiento, son diversas, pero una de las más cotidianas y connaturales es la resolución de problemas. Un contexto tan complejo, en el que de forma acelerada se genera un enorme volumen de información, hace pensar en la necesidad de comprender y valorar el papel de la resolución de problemas como acto epistemológico, que favorece la incorporación de nuevos saberes al sistema de conocimientos del sujeto. Pero, ¿mediante qué procederes se propicia desde la docencia la resolución de problemas para que el estudiante alcance nuevos saberes? Se consultan diversas fuentes de información pertinentes al tema a la par que se muestran varias de las tendencias o perspectivas más sobresalientes en el tratamiento de la resolución de problemas como situación de aprendizaje y sus regularidades. Con este trabajo se expone una visión sintética de los recursos existentes para el tratamiento de la resolución de problemas desde un enfoque epistemológico, lo que propicia un mejor aprovechamiento de esta situación de aprendizaje orientado al aprender a aprender.
Operational Media: Cybernetics, Biopolitics and Postwar Education
Authors: Druick Zoë
Published: July 2020

This article develops the concept of «operational media» to think through the deployment of utility/useful cinema in the context of cybernetically informed educational policy. The paper argues that cybernetic concepts of communication, feedback loops and homeostasis were central to the pragmatic installation of media at the center of postwar mass education. Links are made to the dominance of cybernetic ideas in postwar social science, including social psychology, sociobiology and behaviourism. A consideration of the UN’s operational media allows for a reconsideration of the agency’s communicative mandate as biopolitical and governmental. Educational policies influenced by the UN were doubly concerned with technologized classrooms: cybernetic ideas presented themselves as politically neutral, while offering efficiencies in the delivery of content. Cold war citizenship was thus conceived as a form of training that would pragmatically lead to the rebalancing of a volatile international situation. Carrefour de la vie (1949), made by Belgian filmmaker Henri Storck for the United Nations, is presented as an example of the centrality of mental health for citizenship training in postwar biopolitical regimes. In particular, the tension between the film’s humanist and cybernetic strands are considered. Au Carrefour de la vie is considered as a transitional text, presenting a humanist story of childhood in postwar life that simultaneously prefigures the operation of a controlled society.
Peace in the minds: UNESCO, mental engineering and education
Authors: Duedahl Poul
Published: July 2020

UNESCO – the United Nations Educational, Scientific and Cultural Organization – is often associated with its prestigious world heritage list. For a good reason. The list is undeniable the most popular initiative in the organization’s entire history. But UNESCO is of course more than world heritage. It has over the years been preoccupied with a series of what appears to be extremely diverse topics, such as education for global citizenship, literary translation programs, copyright rules, nuclear power research and technical assistance to developing countries. But how exactly are the many different activities related to peace-making and mentality construction and what exact role does education play besides constituting the «e» in the organization’s name? In order to answer that, I will bring the reader back to three unpretentious but rather important seminars that took place simultaneously in Paris at the beginning of the organization’s existence, because I believe the subsequent projects they initiated embody what the employees at UNESCO initially defined as the organization’s core tasks.
Educational Transfer, Modernization and Development: The Transnational Approach in History of Education Studies
Authors: Ferraz Lorenzo Manuel , Machado-Trujillo Cristian
Published: July 2020

Research focused on the concept of the international or, rather, of international influences and interdependencies, has become a highly recurrent line of work that has been acquiring a notable presence in the field of the History of Education. The objective of this approach to historiographical work is justified as it attempts to explain with a better precision and accuracy what has happened within national borders, or even within more defined perimeters such as regional and local ones. The transfer of ideas and projects, the importation or imitation of pedagogical models, the transfer and influence of educational and school practices, the links and connections between different cultural scenarios and knowledge, the dependencies and interdependencies of international organizations, among other aspects, have led to new and more plausible analyses of educational processes and the political and social will that fostered them. The present work focuses on researching how these practices have evolved, and their networks of connection and exchange, in order to better understand educational and curricular policies in their historical development.
Impact of Glycosylated Hemoglobin on the Prognosis of Patients with Acute Ischemic Stroke Treated with Arterial Thrombolysis
Authors: Ling Wentong , Chen Qiong , Huang Pu , Han Dengke , Wu Wenjun
Published: July 2020

Background: To investigate the impact of glycosylated hemoglobin (HbA1c) on the prognosis of patients with acute ischemic stroke (AIS) treated with intra-arterial thrombolysis (IAT).
Methods: The clinical data of 136 patients with AIS treated with IAT at the Zhongshan City People’s Hospital were retrospectively analyzed. The patients were divided into a high HbA1c group (HHbA1c) (≥6.5%) and a normal HbA1c group (NHbA1c) (<6.5%). According to National Institutes of Health Stroke Scale (NIHSS) score after thrombolysis, patients were divided into a good prognosis group (GP) (≥4 or <4 points reduction) and a poor prognosis group (PP) (≤4 or >4 points reduction).
Results: There were significant differences in the HbA1c and glucose levels, NIHSS scores at admission and at discharge, complication rates, and mortality rates between groups HHbA1c and NHbA1c (P < .05) and between groups GP and PP (P < .05). The multivariate logistic regression analysis showed that HbA1c level (odds ratio [OR] 0.717; 95% confidence interval [CI] 0.545 to 0.889) and NIHSS score at admission (OR 0.894; 95% CI 0.814 to 0.982) were risk factors for neurological improvement in IAT-treated patients with AIS.
Conclusions: HbA1c level is associated with neurological function improvement in IAT-treated patients with AIS and can be used as a serological indicator of poor prognosis.

РОЗВИТОК ІННОВАЦІЙНИХ КОНЦЕПЦІЙ В УКРАЇНІ
Authors: СЛАВА Світлана
Published: July 2020

Інноваційний розвиток є визначальною характеристикою провідних країн. Нині інновації залишаються напрямом, затребуваним не тільки економікою, але і всім суспільством. За останні десятиліття в Україні в нормативних документах визначено декілька концептуальних моделей інноваційного розвитку, проте досягти їх впровадження так і не вдалося. Метою статті є вивчення еволюції концептуальних моделей інноваційного розвитку в Україні, формування їх класифікації за критеріями лінійності та інтегрованості, розробка напрямів їх удосконалення. Узагальнено базові засади пропонованих моделей інноваційного розвиту у відповідних нормативних документах (концепціях і стратегіях) і запропоновано концептуальну конфігурацію інноваційного розвитку для його активізації та впровадження нових організаційних підходів. Використано контентні, дискриптивно-аналітичні та графічні методи дослідження. Виокремлено чотири основних етапи розвитку інноваційних моделей в Україні: лінійна модель (до 1999 р.), інтерактивна модель (1999–2009 рр.), функціонально інтегрована модель (2009–2012 рр.), системно інтегрована і мережева модель (з 2012 р.). Запропоновано концептуальну схему взаємодії в інноваційному процесі. Обгрунтовано, що дієвість інноваційних моделей може запрацювати тільки через відповідну мотивацію – пробудження бізнесового (чи соціального – у випадку соціальних інновацій) інтересу до інновацій, оскільки саме вони є виразниками попиту і реципієнтами інновацій. Така мотивація може сформуватися і посилитися завдяки розширенню та поглибленню взаємодії учасників інноваційного процесу в разі нелінійних та добре інтегрованих моделей інноваційного розвитку, втілення яких має відбуватися через відповідні організаційні формати. Важливими інструментами для впровадження прогресивних інноваційних моделей є розумна спеціалізація, фінансування багатостороннього залучення учасників національних інноваційних систем до спільних дослідних проектів, формування інноваційної культури та вдосконалення управлінських підходів.
ОНОВЛЕННЯ ОСНОВНИХ ЗАСОБІВ В УКРАЇНІ: ПРОБЛЕМИ ЇХ АМОРТИЗАЦІЇ ТА ВИКОРИСТАННЯ

Published: July 2020

Узагальнення статистики по нашій державі та її порівняння з аналогічними показниками інших країн дали підстави для висновку про недоінвестування української економіки. Посилення інвестиційної активності залежить від такого інструменту державної економічної політики, як амортизаційні відрахування, який через імперативні механізми реновації спроможний забезпечити оновлення основних засобів.В основу дослідження покладено структурний і морфологічний аналіз аналітичної та статистичної інформації про процеси амортизації основних засобів.Розглянуто дві принципово різні теоретичні концепції амортизації основних засобів: економічну та фінансову. Зазначено, що в Україні в бухгалтерських і податкових нормативних документах на законодавчому рівні закріплено економічну концепцію амортизації, яка не грунтується на потребах відтворення.Доведено, що у науковій літературі питання призначення амортизації розглядаються в основному з позицій націленості на пожвавлення інвестиційних процесів, тобто з позицій фінансової концепції амортизації. Виявлено історичну причину такої суперечності – формування у роки СРСР у бухгалтерському обліку амортизаційного фонду і особливого рахунку в банку, яке давало підстави розглядати ресурси амортизаційного фонду і, відповідно, амортизаційні відрахування як кошти, які можливо використовувати для технічного переозброєння підприємств.Обгрунтовано тезу про те, що відновлення амортизаційного фонду, аналогічного радянському, означає вилучення частини грошових ресурсів із загального грошового обігу підприємств, що в умовах корумпованої країни не може позитивно вплинути на економіку підприємств. Розглянуто можливість запровадити фінансову концепцію амортизації для максимізації використання амортизаційного ресурсу для потреб оновлення основних засобів.Зроблено висновок про необхідність попереднього нормативно-правового забезпечення. Запропоновано, по-перше, знайти можливість відобразити у бухгалтерському обліку інформацію про невикористані суми амортизаційних відрахувань, а по-друге – збільшити податкову базу податку на прибуток, включивши до неї амортизаційні суми, що не використані як інвестиції.
РОЗКРИТТЯ ПОТЕНЦІАЛУ СМАРТ-СПЕЦІАЛІЗАЦІЇ ДЛЯ ПОДОЛАННЯ РЕГІОНАЛЬНОЇ СТРУКТУРНОЇ ІНЕРТНОСТІ В УКРАЇНІ
Authors: СНІГОВА Олена
Published: July 2020

У статті досліджено передумови становлення та розвитку концепції смарт-спеціалізації в ЄС, визначено основні характеристики смарт-спеціалізації та її спрямованість на пом'якшення регіональних проблем, які перешкоджали реалізації регіонального потенціалу та унеможливлювали технологічні зміни в базових галузях регіональної економіки. З’ясовано, що основним принципом смарт-спеціалізації, який відрізняє цей інноваційний підхід до визначення пріоритетів регіонального розвитку від попередніх, є підприємницьке відкриття. Проаналізовано європейський досвід запровадження смарт-спеціалізації, який грунтується на її чіткому взаємозв’язку з основними складовими європейської політики економічного зростання – регіональною, промисловою та інноваційною. Також розглянуто процес запровадження смарт-спеціалізації в Україні, виявлено його особливості, які полягають у використанні підходів смарт-спеціалізації для врахування регіональних особливостей промислового розвитку країни. Обгрунтовано недоцільність та невиправданість переважання промислової складової над іншими аспектами концепції смарт-спеціалізації. Надано пропозиції щодо вдосконалення використання підходів смарт-спеціалізації в державній політиці України, які спрямовані на її становлення як інструменту нової регіональної політики.
Reflejos del retrato femenino pictórico: la necesidad de una imagen transformadora en México
Authors: García Guerra Gabriela Arhelí , Akhmadeeva Ioulia
Published: July 2020

El retrato artístico y el feminismo en la actualidad transgreden las barreras sociales, utilizan la teoría y la práctica para realizar propuestas con el fin de deconstruir normas y costumbres, con base en las necesidades de su espacio y tiempo. De tal manera, las obras realizadas bajo esta perspectiva, en el siglo XXI, buscan la ruptura de los paradigmas y visibilizar las imposiciones androcéntricas, eurocéntricas y obsoletas. Por ello, el presente trabajo utiliza el análisis de la imagen a través de la noción del espejo relacionada a trabajos teóricos y análisis de dos pinturas hechas por artistas mexicanas contemporáneas. Se busca reflexionar por medio de bases teóricas sobre cómo estas obras permiten visibilizar el entorno como un reflejo de la sociedad a la cual pertenecen. Finalmente,se cuestiona los efectos de lo concebido por retrato femenino y feminismo.
De objeto a cosa. Una reflexión para comprender la pornografía
Authors: Alpízar-Lobo Natasha
Published: July 2020

Las aproximaciones esencialistas y constructivistas a la pornografía suelen concebirse como antagónicas o contrarias. Esto porque, de un lado, se entiende la pornografía desde el contenido de las representaciones y, de otro, desde la emoción y la excitación de quien consume imágenes. No obstante, pese a esos esfuerzos de diferenciación, este ensayo argumenta que hay un denominador común entre ambas: la pornografía se ubica como imagen, es decir, como objeto (acabado, tiene una forma, es un producto). A través de una investigación etnográfica realizada en una comunidad online, Foro de Costa Rica, el ensayo propone pensar la pornografía como cosa o proceso (inacabado, está siempre tomando forma, en constante producción). Esto pretende alejarse de las visiones dicotómicas entre lo esencial y lo construido. Como cierre e invitación, se destaca la importancia social de considerar un posicionamiento como este.
THE WORD ABOUT THE FOUNDATION (OR THE FOUNDATION AS AN ANALOGUE OF THE SUPPORTS OF THE CREATIONS OF NATURE)
Authors: Lushnikov V. V
Published: July 2020

The foundations that serve together with the soils of the foundations of buildings and structures are directly or indirectly borrowed by Man from what was created in Nature - supports of her living and non-living creations: the feet of Man or animals, the roots of plants. Different types of foundations have their counterparts in nature. It is interesting to see how and why these or other forms of Supports appeared, their sizes, how they change, adapt to changes in the environment during the existence of the creation of Nature. And how a Man can use the finds of Nature in his activities in the design of foundations and even buildings and structures. Examples are a pillar foundation that can be cut from a person’s foot; slab foundation - paws of waterfowl; Pile foundation essentially has much in common with the legs of hoofed animals. The heat-insulated foundation can be compared with the paws of a polar bear, whose feet are “lined” with fur. Particular attention is paid to the root system of the tree, which can be considered an ideal foundation. The ability of various trees to adapt to the terrain on which it grows is an example of a possible approach to designing rational types of foundations. The principle of inclusion in the work under the loads of the soil surrounding the root system is implemented in the Tree. At the same time, the roots “reinforce” the surrounding soil, create from it a single system, which perceives the loads acting on the tree. Such an approach is implemented, for example, when constructing foundations or hardening soils using the geotechnogenic system.
THE INFLUENCE OF STRUCTURE FORMING FACTORS ON LOW-CYCLE FATIGUE OF A POLYMER COMPOSITE MATERIAL BASED ON FURFURAL ACETONE MONOMER (FAM)

Research studies of polymer concretes are frequently carried out under the action of static loads while the material is affected by cyclic loads, most often, low-cycle as a result of its work in the structure. In the case when the level of stresses caused by these loads exceeds a certain limit, irreversible damage accumulation processes begin to occur in the material, which lead to the formation of cracks. In the future, the stress concentration at the edge of the crack contributes to its development. Most often cracks occur at the surface of the part, but sometimes in the thickness of the material. This process weakens the section and after some time, when the crack reaches a critical length, the part or structure is destroyed. As a rule, they are destroyed without visible residual deformations, even in cases when they are made of plastic materials. It was suggested that under the influence of variable stresses material gradually degenerates over time, as if "gets tired" (fatigued). Material fatigue is a process of gradual accumulation of damage under the influence of variable stresses, leading to the formation of cracks and destruction of the material. The peculiarities influencing low-cycle stresses on strength characteristics of polymer concretes based on furfural acetone monomer (FAM) are considered in the article. The regression equation has been obtained as a result of experimenting on a polymeric composite material which allowed constructing the response surface of the low-cycle fatigue of the polymeric composite material based on the resin of furfural acetone monomer. A second-order plan for three factors studying low-cycle fatigue of a tested composite material is also presented in the paper. It has been established that the ratio of the polymer component to the filler and the coarse aggregate spreading factor are the fundamental ideas influencing the cyclic durability of polymer concretes while the thickness of the polymer bonding layer is an insignificant factor.

THEORY AND CALCULATION OF ROAD BRIDGES BURIED ABUTMENTS BASES
Authors: Shapiro D. M
Published: July 2020

Buried abutments are most broadly applied in connections of road bridges structures and approach embankments. Embankment and cone weight force influence is the peculiarity of buried abutments bases and foundations constructions conditions of stability and deformation. There is in the article a description of road bridges buried abutments bases engineer calculation method including the complex of limit state checkings and grounding of calculation schemes. The calculations fulfil by calculated schemes of hard-plastic midst theory (on the base of prof. G.M. Shakhunjantc horizontal strengths method) and linear deformation (or elastic-plastic) midst theory. Table data necessitated for calculations are quoted. A way for define the strains in buried abutments bases from cone and approach embankment by the linear deformation midst theory is elaborated by means of making conventional (equivalent) calculated scheme. Non-weighting layer is added to the base, acting load is substitute by equal by value half-endless strip. By it on the real level of base arise normal and tangent strains, conformed with the form approach embankment restricted by slopes from three sides. It is suggested a method of buried abutment base soils stability calculation by the More-Coulomb equation, realizing by mean of strains, obtained in accordance with above descripted way.
