Моменти Ерміта зображень та їхні інваріанти
Authors: Бедратюк Л. П. , Бедратюк Г. І.
Published: November 2022

Хай H ‒ підгрупа афінної групи площини Aff(2,ℝ), яка розглядається разом з своєю природною дією на інтегровні функції від двох змінних визначені в деякій області Ω ⊆ ℝ2. Для фіксованої сім'ї многочленів {Pm,n(x,y)}∞n,n=0 розглянемо функціонал
πm,n=πm,n(f)=∬Ω Pm,n(x,y)f(x,y) dxdy,
який називається P-моментом функції f(x,y) порядку m+n. Дія групи H продовжується на P-моменти за формулою
hπm,n(f)=πm,n(h-1f)=∬Ω Pm,n(x,y)f(h-1(x,y)) dxdy, h ∈ H.
Інваріанти цієї дії називаються P-моментними інваріантами. Якщо функцію f(x,y) ототожнити з напівтоновим зображенням, а за групу H взяти групи обертань, групу розтягів або групу паралельних перенесень площини, то відповідні моменти зображень та їхні моментні інваріанти
широко використовуються в теорії розпізнавання образів. Задача задовільного опису моментних інваріантів задовільно розв'язана лише у найпростішому випадку Pm,n(x,y)=xmyn. В даній статті, для пари бі-ортогональних сімей многочленів Ерміта, задачу знаходження
моментних інваріантів зведено до задачі розв'язання деякого диференціального рівняння в частинних похідних першого порядку, яке виникає при переході від дії групи Лі до дії її алгебри Лі. Для кожної із згаданих груп знайдено явний вигляд дії її алгебри Лі на моменти
Ерміта і вказані явно моментні інваріанти невеликих.

Mathematical Model for Enhancement of Visual Acuity through Electronic System Biofeedback
Authors:   DLCEO, District Literacy and Continuing Education Office, Jaipur, Rajasthan, India, Fageria Om Prakash
Published: November 2022

The majority of people across the world have issues with their vision caused by human ocular refractive errors. Myopia affects 51% of adults, hyperopia affects 38% of adults, and astigmatism affects 27% of adults in the United States. This frequency is much higher in the adult population. 42 percent of global causes of visual impairment are attributable to failure to take prophylactic action against these disorders. This percentage includes presbyopia in adulthood. Visual strain brought on by an excessive use of electronic devices has led to the creation of new techniques and the development of various solutions, including corrective lenses, contact lenses, laser and non-laser refractive surgical operations, and so on. Using a signal electromyography feedback, we describe a technique that may be used to increase a person’s visual acuity. An electronic controlled lens with a power range of -10 to +10 diopters was used in its implementation, along with a LabVIEW interface-connected electromyographic signal gathering equipment. Five separate persons were given the Snellen test to evaluate the proposed system, giving each of them twenty opportunities to complete the exam. Consequently, it is feasible to enhance visual acuity up to 20/20 with an accuracy of 90 percent utilising a biofeedback system, together with other spherical ocular refraction errors such presbyopia, farsightedness, and myopia.
Hungarian Beyond the Border1 On the Contexts of Education, Bilingualism, and Labour Market in the Early 21st Century. The Transylvanian Perspective
Authors: Sorbán Angella
Published: November 2022

Borders are particular (in-between) spaces: they have this side and the other side, which involve several real and imaginary spaces at the same time. For minorities, “beyond the borders” is also a specific space of language use. This paper discusses the correlations between minority bilingualism and social structure characteristics based on sociological surveys, taking as approach the sociology of space and John Ogbu’s ecological cultural model of schooling. It aims to offer an overview of my research carried out on this topic and tries to provide some references for rethinking the sociological implications of minority education considering the experiences of three decades since the fall of communism in Romania. The main results of this research – in concordance with other findings of similar inquiries – show that a mother-tongue education for ethnic Hungarian children in Romania is a necessary but not sufficient condition for reducing the structural gap that Hungarians in Transylvania have inherited from the 20th century. This study is centred on the aspects of interrelation between the language of education and labour market, more specifically on those linked to the attitudes and patterns of behaviour towards the official language, with particular focus on the role that languages play in the society and, in a narrower sense, in self-positioning on the labour market.
“We were that small, special group in that large school with »normal« classes” Education in a Minority Language in the Context of Hungarians From Zagreb
Authors: Katalinić Kristina , Tamaskó Eszter
Published: November 2022

The latest research conducted in the Hungarian community of the City of Zagreb has shown that the Hungarian language is slowly losing its communication functions in informal domains (family, friends, the sphere of intimacy) and is withdrawing before Croatian, i.e., that language shift is in progress. As one of the key factors affecting language shift, school is mentioned as support in families in intergenerational language transmission and language preservation in the community. Croatia has ensured an institutional framework for education in minority languages to its minorities through a series of regulatory acts. However, exercising this right is often followed by numerous difficulties. In case of the Hungarian minority, this is due to geographical dispersity. Nevertheless, during the 1990s, a  Hungarian group in kindergarten, a  bilingual class and nurturing language for primary- and secondary-school pupils were launched in Zagreb. In order to obtain a clearer image of how various class models in a minority language actually function and which problems their participants are faced with, we conducted a preliminary research among younger members of the community who attended classes in Hungarian at least at one point during their education. We completed the results with information obtained through informal conversations with preschool and school teachers as well as through immediate observations of the community.
Building financial flexibility in preparation for Brexit: the case of Irish medium sized enterprises
Authors: McNamara Andrea , O’Connor Thomas , O’Donohoe Sheila
Published: November 2022

The purpose of this paper is to examine the building of financial flexibility by Irish medium sized enterprises in the run-up to Brexit. We analyze changes in firms’ dividends, leverage, cash, investment levels and working capital in the period surrounding the passing of the Brexit referendum to test for stockpiling of financial slack. Whilst we find no evidence of financial flexibility building overall, there is some evidence to suggest that firms incentivised to build such flexibility do so. Cash poor firms appear to build financial slack by way of reducing leverage and increasing their cash reserves. In contrast, cash rich firms increase their capital expenditure using internal and external funds. Interestingly all firms irrespective of their size or financial strength increase their working capital investment and in particular build their inventory levels post the Brexit referendum. Our evidence suggests Irish medium sized enterprises are optimistic of the opportunities post Brexit.

Authors: Rini Mada Sulistiyo
Published: November 2022

Aksi Kamisan (Black Umbrella Protest) merupakan sebuah aksi damai yang muncul sebagai upaya untuk mencari keadilan terhadap peristiwa yang terjadi sepanjang tahun 1998-1999. Kasus yang mana merupakan pelanggaran berat terhadap HAM sesuai dengan UU nomor 26 tahun 2000, seperti halnya tragedi Semanggi I-II dan Trisakti yang berupa penculikan, pembunuhan, penembangan serta penghilangan secara paksa. Sehubungan dengan hal tersebut, dengan adanya penelitian ini berupaya memaparkan sejauh mana perjuangan serta upaya-upaya yang telah dilakukan pemerintah dalam penganganan kasus pelanggaran HAM tersebut sekaligus mengukur keselarasan antara peraturan HAM secara tertulis dan implementasiannya dalam kehidupan. Penelitian ini menggunakan teknik analisis deskriptif dengan model Miles dan Huberman yaitu menerapkan aspek kesinambungan dalam pembahasan. Jenis penelitian yang digunakan yaitu penelitian pendekatan deskriptif kualitatif, dengan teknik pengumpulan data berupa studi pustaka serta penelusuran terhadap arsip-arsip sebelumnya yang berkaitan dengan topik pembahasan. Penelitian ini selain menunjukkan perjuangan yang dilakukan oleh korban serta keluarga yang dirugikan dalam kasus pelanggaran HAM sepanjang tahun 1998-1999, tetapi juga menunjukkan adanya ketidak selarasan terahadap peraturan HAM yang tertulis dengan pengimplementasiannya. Namun begitu, mengingat sejauh ini kasus tersebut terhambat pada Kejaksaan Agung maka komitmen dari negara serta pemerintah adalah satu-satunya variable kunci untuk penyelesaian kasus HAM tersebut.

The Epoch and Personality of Peter the Great in Nikolay Charykov’s Research
Authors: Chernov O. A.
Published: November 2022

The article reviews the academic contribution of Russian historian and diplomat Nikolay Charykov (1855-1930) to our understanding of the reforms by Peter the Great. In his research, Nikolay Charykov argues that the reforms did not result in a radical break with previous Russia's historical path. He stresses that the cultivation of scientific knowledge and labor skills necessary for modernization started in Russia long before Peter the Great because Russia was part of a European system even before Peter the Great. For example, the author points to Ivan III's marriage to Zoe Palaiologina (Sophia Palaiologina); the employment of captive Livonians by Ivan IV; sending Russian youth to study at Western European universities; Boris Godunov's plans to form a European league of Christian sovereigns. Nikolay Charykov focuses in his studies on the reign of Tsar Alexei Mikhailovich, pointing to his plans to increase the involvement of Westerners in various spheres of life in Russia. Moreover, Nikolay Charykov shows that the personality of the future Emperor was formed under the influence of Russia's increasing interaction with European countries. He concludes that the development of Russia before Peter led to Peter's reforms. He saw the struggle between Sophia and Peter as an interpersonal struggle for power, which in no way violated the primary trend of Russia's development. Peter's reforms became a logical and natural consequence of the previous processes. The merit of Peter was that he successfully continued the previously started transformations by adding to them his character and thinking, which led to the birth of the Russian Empire.

Published: November 2022

Under the conditions of climatic fluctuations, which often lead to various stresses during the growing season, the need to increase the genetic diversity of agricultural plants by various methods is becoming increasingly important. One of the methods is experimental mutagenesis, which has proved to be promising for agricultural practice both in Russia and abroad. Based on literature sources, a brief history of the discovery of mutagenesis induced by ionizing radiation and chemicals is presented. Information about the development of a fundamentally new theory of chemical mutagenesis by I.A. Rapoport and of methods of its application is reviewed. The discovery of phenotypic activators of plant growth and development makes it possible under current conditions to increase plant resistance to the effects of abiotic and biotic environmental factors and to reduce significantly pesticide load on agrocenoses. These claims are confirmed by studies and practical tests of para-aminobenzoic acid (PABA). Some facts related to the struggle of outstanding geneticists, physicists and biologists in the post-Stalin period against the anti-scientific trends implemented by Lysenko, which were destructive for agriculture, are presented.

Beyond the Deliverable

Published: November 2022

Those who participate in service-learning/civic engagement (SLCE) in engineering have a common practice of reflecting on partnerships to determine if they were successful and how they might be improved. But what makes a partnership successful? We wanted to learn more about how and why to quantify partnership success to think “beyond the deliverable,” which is often the singular focus of engineering SLCE projects. To this end, we created a rubric for three dimensions of partnership that we selected after consulting engagement partnership literature: transactional, cooperative, and transformational. Using this rubric, we assessed the 55 completed partnerships of the LSU Community Playground Project (LSUCPP) by plotting scores in a 3-axis coordinate system (transactional as the x-axis, cooperative as the y-axis, and transformational as the z-axis) where a placement closer to (3.0, 3.0, 3.0) means a more universally successful partnership. Within each dimension of partnership, we assessed design, people, and process in equal measure to ensure that we paid adequate attention to each of these key aspects of engineering SLCE efforts. Further, part of this assessment involved surveying constituents (community partners, students, and faculty) about the transformational dimension of completed partnerships. Results showed  that our partnerships had high transactional (2.4) and cooperative (2.5)  mean scores overall, with a lower transformational mean (1.8). We also identified a transactional/cooperative threshold (2.0/2.0) at which the chance of having a transformational partnership went up; overall, our percentage of highly (2.0 or higher) transformational partnerships was 58%, but 70% of our partnerships that reached the threshold were highly transformational. The aspects of transformation most often identified by our survey respondents included building your capacity personally (81%), building lasting connections with colleagues (73%), and building your capacity professionally (70%). We believe that the method of holistic assessment for community-university partnerships presented here can lead to better engaged partnerships and can be adapted by others who wish to improve their SLCE engineering partnerships.

A pandemia da Covid-19 trouxe impactos para os estudantes da graduação. Poucos são os estudos dedicados a compreender em que condições alunos com deficiência enfrentaram a implantação do ensino remoto emergencial. Foi realizada uma pesquisa que contou com a participação de 156 alunos com deficiência, por meio de um questionário online. Buscou-se identificar se esses alunos tiveram suporte adequado durante a pandemia e os recursos e as tecnologias preferidos nesse cenário. Os resultados indicam que a disponibilidade de recursos foi frágil e muitos estudantes não receberam nenhum suporte. Esse é um grupo já vulnerável, para quem as questões socioeconômicas significaram um obstáculo importante durante a pandemia, somadas à ausência de estratégias específicas voltadas à saúde mental.

O estudo visa investigar como professoras de Educação Especial organizaram e avaliaram o trabalho pedagógico no ensino remoto emergencial, bem como compreender suas condições de trabalho em escolas públicas de um município do interior paulista. Os dados empíricos foram obtidos por meio de um questionário e relatos de experiência. Os resultados apontam que, diante de condições tecnológicas e sociais precárias e adversas, as docentes de Educação Especial sustentam o trabalho no coletivo escolar, na relação com as famílias e no vínculo com os alunos. Discute-se que os gestos de resistência político-pedagógica podem emergir por meio do compromisso com o ensino; e da função da escola em promover a relação dos estudantes com deficiência com conhecimentos atribuídos de sentido social.

Objective: Atrial fibrillation is a strong independent risk factor for cardioembolic stroke, with a significant impact on morbidity, mortality and healthcare costs. The aim of our study is to investigate left atrial mechanical function in healthy subjects and patients with atrial fibrillation paroxysms less than 48 hours with low risk of thromboembolic complications at 1 and 28 days after restoration of sinus rhythm.

Methods: Thirty-six healthy controls and patients with paroxysms of non-valvular atrial fibrillation less than 48 hours (n=25) with low-risk CHA2DS2VASc score were included in the study. The mechanical function of the left atrium  (LA) was investigated by the 2D speckle tracking program. Transthoracic echocardiography was performed on the 1st and 28th days after restoration of sinus rhythm by pharmacological cardioversion.

Results: Despite the absence of differences in left ventricular systolic function and LA size between the groups, there was a significant decrease in LA deformation and strain rate on day 1 immediately after sinus rhythm recovery in the patients. In the pump phase, the decrease was about 3%, reservoir phase – 10%, and conduit phase – 7% compared to the control group. The strain rate also decreased in the patient group: -1.5 s-1 versus control: -2.14 s-1 (p<0.0001). On the 28th  day after restoration of sinus rhythm, there were significant changes in reservoir and conduit functions in patients group in comparison with control group. Global longitudinal LA strain (reservoir phase) decreased to 7%, conduit phase decreased to 11% compared with the control group. In patients group we can see the dynamics during 28 days: pump phase and strain rate were significantly improved, however reservoir and conduit did not significantly change and were lower than in healthy.

Conclusion: Mechanical function of the LA in patients with non-valvular atrial fibrillation and low risk of thromboembolic complications, studied with speckle tracking on the first day was significantly impaired compared with the control group (reservoir phase and strain rate). By day 28, mechanical function improved compared to day 1, but reservoir phase remained significantly lower than  normal.

Examining the Relationship between Employee Effort and Earnings Management: Evidence from non-Financial Tunisian Companies

Authors: Ben-Ahmed Kais
Published: November 2022

This paper examines the relationship between employee effort and earnings management. Data on working hours and discretionary cumulations of 29 non-financial companies listed in Tunisia are used. With an increased activity of employees, we find less profit management in Tunisian companies. This result evolves more critical when incomes are more predictable and persist after controlling for delayed endogeneity. However, we also find that increasing employee effort increases the likelihood of positive gains being realized for non-financial businesses. Our findings have important implications for investors and regulators looking to restrict earnings management.
Trepanation revisited in COVID-19 era: A perspective on craniotomy during current pandemic, surgical technique, and complications avoidance
Authors: Krishna Gopal , Singh Ishwar
Published: November 2022

Background:

Craniotomy creates maximum aerosols threatening the health care workers (HCWs) of operation room. The technique of trepanation and measures to avoid complications has never been described in the literature. The time taken for craniotomy by different instruments has also never been compared.

Methods:

The study included only COVID-positive patients who underwent surgery. Craniotomy was performed using trephine, pneumatic/power drill (PD), and Hudson brace-Gigli saw (HB-GS). Trepanation as done in 32 patients. The generation of aerosols and time taken for craniotomy by these instruments was observed. The droplet spread over a waterproof graph paper of 10 × 10 sq. cm was calculated in 13 cases of all the three craniotomy methods. The technique of trepanation and maneuvers to overcome complications was discussed.

Results:

There was a gross difference in aerosol production and soiling of the surgical drapes, floor, surgeon’s glove, gowns, face shield, goggles, etc. The average number of droplet aerosol in trepanation group was 4.76, 23.6 in drill and 21.3 in Gigli saw method. The average time taken for trepanation, PD, and HB-GS craniotomy was 4.8, 22.8, and 24.4 min, respectively. One mortality secondary to COVID was noted. All the HCWs assisting trepanation were negative for COVID-19 during postoperative follow-up of 7 days. However, 13 members of the surgical team which assisted in electric drill and HB-GS methods were COVID-positive.

Conclusion:

Trepanation should be the preferred method of craniotomy during COVID-19 pandemic as it is associated with the least aerosolization and is the most time efficient.

Географическое положение Республики Саха (Якутия), занимающей значительную часть Арктической зоны России, определяет ее особую роль и ответственность в вопросах освоения развития арктических территорий. Экосистемы Якутии являются уникальным резервом биосферы планеты, более 80% территории не тронуто промышленно-хозяйственным освоением. Экстремальные природно-климатические условия, фрагментарное промышленное освоение, низкая плотность населения, неразвитость транспортной и энергетической инфраструктуры, высокая ресурсоемкость и зависимость от северного завоза, хрупкость экологии – это специфические черты Арктики. Они диктуют необходимость постоянной заботы государства о жителях Арктики. Говоря об Арктике, невозможно не упомянуть её огромный энергоресурсный резерв – около 20% мировых запасов нефти и газа. В районах Арктики есть уникальные возможности для применения лучших технологий, материалов и инноваций для применения в промышленности и производстве в силу хрупкости арктической экосистемы. Текущее состояние и темпы развития арктических территорий Республики Саха (Якутия) во многом не соответствуют их потенциалу и значению. Исходя из приоритетов государственной политики в развитии Арктики важно выстраивание четкой и единой системы по развитию арктических территорий, учитывающих особую специфику макрорегиона.

The geographical position of the Republic of Sakha (Yakutia), which occupies a significant part of the Arctic zone of Russia, determines its special role and responsibility in the development of the Arctic territories. Ecosystems of Yakutia are a unique reserve of the planet’s biosphere, more than 80% of the territory is untouched by industrial and economic development. Extreme natural and climatic conditions, fragmented industrial development, low population density, underdeveloped transport and energy infrastructure, high resource intensity and dependence on northern delivery, fragility of the ecology – these are specific features of the Arctic. They dictate the need for constant state care for the inhabitants of the Arctic. Speaking about the Arctic, it is impossible not to mention its huge energy reserve – about 20% of the world’s oil and gas reserves. The Arctic regions have unique opportunities to apply the best technologies, materials and innovations for industrial and manufacturing applications due to the fragility of the Arctic eco-system. The current state and rates of development of the Arctic territories of the Republic of Sakha (Yakutia) largely do not correspond to their potential and significance. Based on the priorities of state policy in the development of the Arctic, it is important to build a clear and unified system for the development of the Arctic territories, taking into account the special specifics of the macroregion.
