INTERCONNECTION OF INFORMATICS AND MATHEMATICS IN SCHOOL AT AN EARLY STAGE OF STUDY
Authors: Kondor Daryna , Yurchenko Nataliia
Published: December 2021

The relevance of the chosen research topic is to highlight the issue related to the formation of algorithmic thinking in primary school students in computer science lessons. The aim of the article is to identify the role of computer science and mathematics in the formation of algorithmic thinking style. To achieve this goal, the following methods were used: analysis, comparison, observation, synthesis. Statistical data processing was also used. The article states that the basis for algorithmic thinking is the formation of mathematical competence of junior high school students. In computer science lessons, students apply the acquired knowledge of mathematics by practical methods. Therefore, the appropriate level of students’ knowledge of mathematics is important. The article presents a table of success levels in mathematics and computer science for third and fourth graders of one of the primary schools in Uzhhorod. The level of success in studying mathematics was compared with the level of success in studying computer science by third-graders and similarly by fourth-graders. When comparing the two empirical distributions, we used the two-sample Kolmogorov-Smirnov agreement criterion. We have shown that the selected general populations are stochastically equivalent. Comparing the results of educational achievements in computer science and mathematics of students of 3rd and 4th grades, we came to the conclusion that the formation of mathematical competence helps in solving problems in computer science lessons that require logical thinking and algorithmic skills. We believe that more attention should be paid to the study of the basics of programming in school, the development of logical and algorithmic thinking in mathematics and computer science, as well as in elective classes.
INNOVATION − CONDITIO SINE QUA NON DEVELOPMENT OF HIGHER PEDAGOGICAL EDUCATION?
Authors: Leontieva Inna
Published: December 2021

The research is an attempt to understand the nature of «innovation» phenomenon of, to outline its essential features. The urgency of the problem is due to the fact that in the context of new globalization challenges, paradigm shifts and transformational processes, the concept of innovation acquires the meaning of the strategic imperative of education of the third millennium, and innovation is considered a prerequisite (conditio sine qua non) for higher education. The purpose of the article is to clarify the essence of the phenomenon of «innovation», its genesis in the development of domestic and foreign higher pedagogical education, outline and analyze the determinants that define innovation as a prerequisite for the development of domestic higher pedagogical education. To achieve this goal, theoretical methods were used: analysis and generalization of scientific sources to outline the genesis, essence and attributive characteristics of the phenomenon of «innovation»; terminological analysis to clarify the basic concepts of the study; analysis of normative-legal documents regulating the development of higher education in Ukraine to clarify the legal support of the imperative of innovation in the development of higher pedagogical education; generalization and systematization of existing experience on this problem to formulate their own views on the innovative development of higher pedagogical education in a modern university as a scientific category.The term «innovation» nowadays is perhaps the most used in the context of paradigm and legislative changes, standardization of higher education, transformation of the content and technology of training, changing approaches to the organization and conduct of training and more. Changes in education and science, their development and constant renewal are a necessary condition for the life of modern society, and innovation becomes its alter ego. Having come a long way in history, «innovation» is now often seen as a tool for transforming various areas of socio-cultural activity; as an innovation that is not yet widespread in social activities or production; as the end result of the introduction of scientific and technological progress for the sustainable development of society. This contradiction of interpretations of the phenomenon of «innovation», on the one hand, and declaring it as a key tool for building a society of sustainable development, highlighted the need to explore the nature of «innovation», understand its determinism and basic elements, outline conceptual approaches to modernization of higher education. principles.

This study aimed to examine the level of operational risk disclosure among Shariah-compliant companies in Malaysia. The relationship between corporate governance characteristics and operational risk disclosure was also examined by focusing on board characteristics, i.e. independent directors, audit committee meetings, Muslim directors, women directors and education levels of the directors. The sample comprised of 285 Shariah-compliant companies listed in the ACE Market of Bursa Malaysia for the financial years 2014 to 2018. The study used content analysis to assess operational risk disclosure. The information disclosure was scored using an adapted disclosure index. Findings revealed that the disclosure of operational risk information in Shariah-compliant companies was at a moderate level, specifically not more than sixty per cent. More importantly, the analysis showed a positive significant relationship between a woman director and operational risk disclosure. However, a negative significant relationship was found between Muslim directors and operational risk disclosure. Other independent variables were found to have no relationship with the operational risk disclosure. The findings may provide future researchers and regulators with references for assessing the level of operational risk disclosure among public listed companies in Malaysia and are expected to deliver some improvement in examining other characteristics to strengthen the governance practices in Malaysia. Keywords: operational risk disclosure, women director, Muslim director, Shariah-compliant companies

Authors:   CIU Business School, Chittagong Independent University, Bangladesh, Jahan Nusrat , Abdullah Mohammad Nayeem ,   CIU Business School, Chittagong Independent University, Bangladesh
Published: December 2021

This study examined the effect of the Covid-19 health crisis on the volatility of sector-wise securities return listed in the Chittagong Stock Exchange (CSE) and compared this volatility with the pre-pandemic context. This study focused on the Chittagong Stock Exchange because this bourse offers a platform for negotiability and transferability of securities to investors in Chittagong and also plays a significant role in capital mobilization and the industrial development of Bangladesh. A sample of 90 securities under 19 sectors listed in the CSE were examined. The trend analysis indicated that Bank, Food, Footwear, Leasing, Life Insurance, Electrical and Engineering and Mutual Funds had same level of volatility between the Pre-Covid and Post-Covid time periods. Only four sectors, including Energy, Telecommunication, General Insurance and Miscellaneous sectors displayed a higher Post-Covid volatility relative to the Pre-Covid context. The result indicated that volatility of return was not the same for 19 sectors in the CSE over the selected time period. The researcher discovered that high and low periods of deaths had a significant impact on weekly volatility of return on 19 sectors of the CSE. However, the difference in volatility of return across all sectors between the Pre-Covid and Post-Covid time periods were not statistically significant from each other. Keywords: volatility of return, stock market, covid-19

Lincoln Grosso: sente o groove | Lincoln Grosso: feel the groove
Authors: C. Grosso Lincoln , Silva Jonathas Magalhães Pereira da
Published: December 2021

FOTOS QUE BUSCAM o groove. Para alguns é um sulco, uma fenda; para outros, uma incessante busca por um sentido inespecífico, mas que cria sinto­nia, cadência, balanço. Enfim, um significado que é percebido, mas não facil­mente traduzido em palavras. O conceito é presente no meio musical do jazz ao funk. A busca pelo groove é parte da essência da criação. Imagine transportar esse sentimento de ritmo, padrão, memória e sentimento para documentos de vivências. Uma festa, um lugar, um momento captado por uma lente que tudo congela e guarda. Guarda e revela. Revela e atiça a imaginação.
”Meneekö kirkko rikki?” Pappien näkemykset samaa sukupuolta olevien kirkollisen avioliittoon vihkimisen seurauksista
Authors: Kallatsa Laura
Published: December 2021

Samaa sukupuolta olevien avioliitosta on muodostunut 2000-luvun ensimmäisten vuosikymmenten näkyvin keskustelunaihe Suomen evankelis-luterilaisessa kirkossa. Avioliittolain muututtua vuonna 2017 kirkollinen vihkimiskäytäntö ei muuttunut, vaikka kirkkoon kohdistui kova paine arvioida avioliittokäsitystä uudelleen. Tässä artikkelissa tarkastelen, millaisia seurauksia samaa sukupuolta olevien kirkollisella avioliittoon vihkimisellä pappien mukaan olisi. Tutkimusaineisto koostuu 506 Suomen evankelis-luterilaisen kirkon papin vastauksista sähköiseen kyselylomakkeeseen. Tutkimusmenetelmänä on aineistolähtöinen sisällönanalyysi. Tutkimus osoittaa, että pappien esittämät seuraukset ovat jaettavissa neljään teemaan: 1) Kirkko osana suomalaista yhteiskuntaa, 2) Kirkon sisäinen pirstaloituminen, 3) Kristillisten arvojen vahvistuminen ja murentuminen sekä 4) Toisia kunnioittava vai syrjivä tulevaisuus?
Immunoterapia na jad owadów błonkoskrzydłych – kiedy i kogo kwalifikować do leczenia
Authors: Sułkowska Weronika , Czarnobilska Ewa
Published: December 2021

Alergia na jad owadów błonkoskrzydłych to najczęstsza przyczyna wstrząsu anafilaktycznego u dorosłych, a druga po alergii pokarmowej u dzieci. W warunkach polskich najczęstszymi przyczynami alergii są użądlenia przez pszczoły miodne (Apis mellifera), osy (Vespula spp.) oraz szerszenie (Vespa spp., częściej u osób już wcześniej żądlonych przez osy).
Skutkiem użądlenia jest zazwyczaj odczyn miejscowy, jednak ok. 3% dorosłych i 0,5% dzieci reaguje odczynami ogólnoustrojowymi o charakterze anafilaksji. Diagnostyka nadwrażliwości na jady bywa trudna, szczególnie gdy wywiad nie wskazuje jednoznacznie na owada sprawczego. Jej podstawą są testy skórne z jadem osy i pszczoły: punktowe (prick test) i śródskórne o łącznej czułości 94%, i oznaczenie poziomu specyficznych IgE, których czułość wynosi od 83% do 100%. Postawą leczenia jest immunoterapia swoista, do której są kwalifikowani pacjenci z ciężkimi reakcjami anafilaktycznymi i udowodnionym mechanizmem IgE-zależnym alergii. W wyjątkowych sytuacjach do leczenia są kwalifikowane osoby z dużymi odczynami miejscowymi narażone na częste użądlenia z racji wykonywanej pracy oraz z izolowanymi zmianami skórnymi, które znacznie obniżają jakość ich życia. Immunoterapia swoista jest jedyną skuteczną metodą leczenia, trwa 3–5 lat, a jej skuteczność wynosi 91–96% przy alergii na jad osy oraz 77–84% przy alergii na jad pszczoły.

Published: December 2021

El objetivo general de la presente investigación es analizar el impacto que la pandemia por coronavirus ha tenido en la salud psicológica de las personas atendidas en la clínica universitaria del CPA-UAM. Se comparan los datos pre- y post-pandemia de las personas que acudieron al centro entre 2016 y 2021, tanto para tratamiento regular (N= 535, 448 pre-COVID, 87 post-COVID), como para atención telefónica gratuita durante el confinamiento y la desescalada (N= 73 personas, 98 llamadas). Los tratamientos tuvieron un enfoque cognitivo-conductual.  Se encontró un aumento notable de demanda de tratamiento por problemas de ansiedad a partir de la llegada de la pandemia, y también de la gravedad que presentaban esos casos. También la ansiedad fue la principal demanda de atención telefónica durante el confinamiento, aunque hubo un incremento de demandas específicas, como duelo y miedo al contagio. No se encontraron diferencias en ningún otro aspecto de los tratamientos, excepto en el número de demandas de atención en lína a partir de la pandemia. Es imprescindible adaptar las terapias y la formación de los terapeutas a la nueva realidad post-pandemia y garantizar servicios de atención psicológica de calidad para la población.
Pensiero progettuale: Innovazione e protezione delle idees
Authors: Méndez Reátegui Rubén , Álvarez Meythaler Amparo
Published: December 2021

Desde un enfoque de Design Thinking, este artículo pretende explicar cómo los procesos creativos en las organizaciones, expresados en un contexto de efervescencia de los derechos de propiedad, requieren la formulación de métodos más rigurosos de obtención y evaluación de la información, que permitan mitigar los efectos asimétricos y la pérdida de eficiencia y eficacia de los esfuerzos realizados por las empresas. Se analizan tres posibles intervenciones para que el proceso creativo genere conocimientos valiosos. Las ideas pueden patentarse durante las fases iniciales: orientación del pensamiento creativo, uso de la tecnología a través de herramientas de registro digital y estrategias empresariales sostenibles centradas en el comportamiento humano. Se concluye que partir de un pensamiento de diseño requiere sistematizar e incorporar mayor rigor en el proceso creativo para facilitar los procesos de registro de derechos de propiedad sobre un producto original de la organización. 

A partire da un approccio di Design Thinking, questo articolo mira a spiegare come i processi creativi nelle organizzazioni, espressi in un contesto di effervescenza dei diritti di proprietà, richiedono la formulazione di metodi più rigorosi per ottenere e valutare le informazioni, che permettono l’attenuazione degli effetti asimmetrici e la perdita di efficienza ed efficacia degli sforzi fatti dalle aziende. Si analizzano tre possibili interventi affinché il processo creativo generi un prezioso know-how. Le idee possono ricevere un trattamento organizzato durante le fasi iniziali: guida del pensie­ro creativo, uso della tecnologia attraverso strumenti di registro digitale, e strategie aziendali sostenibili focalizzate sul comportamento umano. Si conclude che partire da un pensiero progettuale richiede la sistematizzazione e l’incorporazione di un mag­gior rigore nel processo creativo per facilitare i processi di registrazione dei diritti di proprietà su un prodotto originale dell’organizzazione.

Authors: Schnobli Carina de Camargo , Bernardes Fernando Frederico
Published: December 2021

Este trabalho buscou analisar como está acontecendo os desdobramentos do ensino remoto, na disciplina de Geografia, em algumas escolas de Francisco Beltrão/PR. Para isso, três escolas foram eleitas (como amostragem do estudo de caso), a fim de viabilizar a presente pesquisa. As escolas designadas são as seguintes: Colégio Estadual Mário de Andrade, Colégio Estadual Cristo Rei e Colégio Estadual Professor Léo Flach. Como contextualização e embasamento teórico utilizou-se, principalmente, dos decorrentes pensadores: Callai (2011, 2012), Castellar (1999, 2012), Cavalcanti (1998, 2012) e Straforini (2004). A partir destes, discorreu sobre o Ensino de Geografia, vinculando tais reflexões teóricas com o ensino remoto, que vem sendo implementado em decorrência da pandemia de Coronavírus. Na sequência, foi disponibilizado para as turmas de 9º e 3º anos, dos Ensino Fundamental e Médio, respectivamente, das escolas supramencionadas, um questionário visando identificar os benefícios e malefícios do ensino remoto no componente curricular de Geografia. Este estudo de caso, como contributo principal, permitiu constatar que o ensino remoto tem sim seus proveitos, entretanto, sem sombra de dúvidas, nunca substituirá a qualidade do ensino presencial. Para além, este artigo almejou ser um registro qualificado (acadêmico), deste momento atípico que estamos vivenciando, principalmente no que diz respeito às questões escolares/pedagógicas.

O presente artigo tensiona o conceito de negligência familiar, a partir de relatos de crianças de cinco anos de idade, durante uma pesquisa realizada em uma escola da rede municipal de Educação Infantil, em uma cidade da Região Metropolitana de Porto Alegre/RS. O objetivo central da investigação buscou compreender como as crianças percebiam e interpretavam as violências de gênero vividas no âmbito familiar e/ou no seu entorno. A partir das teorizações propostas pela Sociologia da Infância, foram utilizadas estratégias para promover esse debate com as crianças, através das rodas de conversa e leituras literárias. Os resultados apontaram para o que chamamos de modos de sobrevivência como estratégia que as famílias desassistidas se veem impelidas a criar para estabelecer a segurança das crianças no ambiente doméstico.
ЗАСТОСУВАННЯ КВАДРАТУРНИХ ФОРМУЛ ПРИ МОДЕЛЮВАННІ ГРАВІТАЦІЙНОГО ПОЛЯ STHA-ФУНКЦІЯМИ
Authors: Dzhuman Bohdan , Zablotskyi Fedir
Published: December 2021

Актуальність теми дослідження. На сьогодні при побудові висотних мереж найточнішими залишаються традиційні методи геометричного нівелювання. Попри те, що застосування супутникових технологій є значно економічно вигіднішим і дозволяє отримати координати субміліметрового рівня точності, відсутність високоточних моделей геоїда не дозволяє повноцінно замінити ними традиційні методи. Тому дослідження і покращення методів і алгоритмів побудови поверхні геоїда є актуальною задачею. Постановка проблеми. Є чимало методів побудови поверхні геоїда. Останнім часом дедалі більшу популярність набирають параметричні методи, в основі яких лежить використання сферичних функцій Лежандра дійсного ступеня. До основних недоліків такого роду методів можна віднести те, що вони не є ортогональними у своїй області визначення. Виняток становлять STHA-функції. Відповідно при їх використанні можна застосувати квадратурні формули (напр., другий метод Неймана). Основна проблема полягає в тому, що такі квадратури мають дуже погану збіжність, і необхідно розробити модифіковані методи, які дозволятимуть обчислювати невідомі коефіцієнти мо-делі з меншими витратами часу. Аналіз останніх досліджень і публікацій. Розглянуто публікації, в яких висвітлено основні етапи побудови потенціальних полів з використанням сферичних функцій дійсного ступеня. Виділення недосліджених раніше частин загальної проблеми. Використання STHA-функцій для побудови високоточного регіонального гравітаційного поля є практично надзвичайно складною задачею через повільну збіжність квадратурних рядів.Постановка завдання. Розробити алгоритми, які дозволять покращити збіжність квадратурних рядів при використанні STHA-функцій для побудови високоточного регіонального гравітаційного поля.Виклад основного матеріалу. Розроблено модифікований метод застосування квадратурних формул Гаусса при моделюванні регіонального гравітаційного поля Землі STHA-функціями. Це дозволить будувати високоточні регіональні поверхні геоїда без надмірного використання ресурсів і часу. Висновки відповідно до статті. Запропоновано та апробовано методику для оптимізації обчислення невідомих гармонічних коефіцієнтів моделі регіонального гравітаційного поля з використанням квадратурних формул Гаусса.
Space-time fractional diffusion: transient flow to a line source
Authors: Raghavan Rajagopal , Chen Chih
Published: December 2021

Nonlocal diffusion to a line source well is addressed by space-time fractional diffusion to model transients governed by both long-range connectivity and distorted flow paths that result in interruptions in the geological medium as a consequence of intercalations, dead ends, etc.The former, superdiffusion, results in long-distance runs and the latter, subdiffusion, in pauses. Both phenomena are quantified through fractional constitutive laws, and two exponentsαandβare used to model subdiffusion and superdiffusion, respectively. Consequently, we employ both time and space fractional derivatives. The spatiotemporal evolution of transients in 2D is evaluated numerically and insights on the structure of solutions described through asymptotic solutions are confirmed numerically. Pressure distributions may be classified through two situations (i) wherein 2α = β + 1 in which case solutions may be grouped on the basis of the classical Theis solution, and (ii) wherein 2α ≠ β + 1 in which case conventional expectations do not hold; regardless, at long enough times for the combined case, power-law responses are similar to those for pure subdiffusive flows. Pure superdiffusion on the other hand, although we consider a system that is infinite in its areal extent, interestingly, results in behaviors similar to steady-state flow. To our knowledge, documented behaviors are yet to be reported.
“George Orwell Invented Journalism Studies”
Authors: Meuret Isabelle
Published: December 2021

To inaugurate our series of conversations with scholars in journalism studies with a view to securing some useful insights into the history and practice of journalism education, Prof. Richard Lance Keeble appeared an obvious choice. Now an Honorary Professor at Liverpool Hope University, Prof. Keeble was first director of the International Journalism MA, then director of the Journalism and Social Science BA, at City University, London (1984-2003). He was then appointed Professor of Journalism (2003-present) at Lincoln University where he also became acting head of the Lincoln School of Journalism (2010-2013) and later a Visiting Professor at Liverpool Hope University (2015-2019). Prof. Keeble has been the recipient of prestigious and distinguished prizes, namely the National Teaching Fellowship Award (2011) and the Lifetime Achievement Award for services to journalism education (2014), the latter bestowed by the Association for Journalism Education in the UK.
Parallel to his academic career, Prof. Keeble has always been a practising journalist. On completion of his studies in Modern History at Keble College, Oxford University (1967-70), he started a career in journalism, first as sub editor at the Nottingham Guardian Journal/Evening Post (1970-73) and then at the Cambridge Evening News (1973-77). He was deputy editor, then editor, of The Teacher, the weekly newspaper of the National Union of Teachers (1977-84). His dual pedigree in journalism, as a practitioner and a professor, led him to take on many editorial responsibilities. He is emeritus editor of Ethical Space: The International Journal of Communication and Ethics and joint editor of George Orwell Studies and is also on the board of an impressive number of journals, among which are Journalism Studies, Digital Journalism, Journalism Education, International Journal of Media and Cultural Politics, Media Ethics, Journalism: Theory, Practice & Criticism, to name just a few. Prof. Keeble was also Chair of the Orwell Society1 (2013-2020) and has authored or edited no less than 44 books. They include Ethics for Journalists and The Newspapers Handbook,2 respectively on their second and fifth editions, as well as several volumes on George Orwell, investigative journalism, and the British media.
It was an honour and privilege to talk to Prof. Keeble in a phone interview on March 25, 2021. The conversation was transcribed while some passages were edited for clarity. I hereby express my immense gratitude for his time, generosity, expertise, and humour. It is such a thrill to start our series of interviews in a way that only makes us want more such conversations.
The efficacy of cystoperitoneal shunting for the surgical management of intracranial arachnoid cysts in the elderly: A systematic review of the literature
Authors: Merola Joseph , Manivannan Susruta , Ooi Setthasorn , Li Chia Wen , Makwana Milan , Lang Jozsef , Leach Paul , Zaben Malik J.
Published: December 2021

Background:

Intracranial arachnoid cysts (AC) are benign, cerebrospinal fluid filled spaces within the arachnoid layer of the meninges. Neurosurgical intervention in children and young adults has been extensively studied, but the optimal strategy in the elderly remains unclear. Therefore, we performed a single center retrospective study combined with a systematic review of the literature to compare cystoperitoneal (CP) shunting with other surgical approaches in the elderly cohort.

Methods:

Retrospective neurosurgical database search between January 2005 and December 2018, and systematic review of the literature using PRISMA guidelines were performed. Inclusion criteria: Age 60 years or older, radiological diagnosis of intracranial AC, neurosurgical intervention, and neuroradiological (NOG score)/clinical outcome (COG score). Data from both sources were pooled and statistically analyzed.

Results:

Our literature search yielded 12 studies (34 patients), which were pooled with our institutional data (13 patients). CP shunts (7 patients; 15%), cyst fenestration (28 patients; 60%) and cyst marsupialisation/resection (10 patients; 21%) were the commonest approaches. Average duration of follow-up was 23.6, 26.9, and 9.5 months for each approach, respectively. There was no statistically significant association between choice of surgical intervention and NOG score (P = 0.417), COG score (P = 0.601), or complication rate (P = 0.955). However, CP shunting had the lowest complication rate, with only one patient developing chronic subdural haematoma.

Conclusion:

CP shunting is a safe and effective surgical treatment strategy for ACs in the elderly. It has similar clinical and radiological outcomes but superior risk profile when compared with other approaches. We advocate CP shunting as first line neurosurgical intervention for the management of intracranial ACs in the elderly.

Published: December 2021

Sekolah Islam Terpadu (SIT) menganut prinsip muwasafat yang merupakan corak gerakan militan Tarbiyatul al-Islamiah. Corak keagamaan ini nampak tidak terlalu berpengaruh, bila dilihat bagaimana besarnya minat masyarakat pada SIT, meskipun sebagian besar siswa berasal dari latar belakang ideologi keagamaan berbeda. Perbedaan ini melahirkan kemungkinan khusus bagi tumbuhnya sikap keberagamaan siswa. Penerimaan terhadap SIT dapat terbentuk karena SIT mampu menguasai faktor-faktor pemasaran jasa pendidikan, atau SIT memang terbuka terhadap keragaman. Tulisan ini bertujuan untuk mengetahui bagaimana keberagamaan dipraktikkan di SIT dan pengaruhnya bagi sikap keberagamaan siswa. Penelitian menggunakan metode silang antara wawancara, observasi dan dokumentasi untuk memotret praktik keberagamaan SIT, dan metode angket untuk mengukur sikap siswa. Sikap keberagamaan siswa dianalisa menggunakan skala Gutaman. Hasil penelitian menunjukkan prinsip keagamaan di SIT dipraktikkan secara terbuka. Keterbukaan keberagamaan diterapkan melalui penamaan, manajerial dan kurikulum. Sikap keberagaamaan siswa di SIT menunjukkan cenderung terbuka 50,54% lebih banyak, dibadingkan dengan sikap siswa yang tertutup sebanyak 49,46%. Penelitian ini berkontribusi dalam mengembangkan teori sikap keberagamaan siswa dalam dunia pendidikan Islam.

Поиск типичных подпоследовательностей временного ряда является одной из актуальных задач интеллектуального анализа временных рядов. Данная задача предполагает нахождение набора подпоследовательностей временного ряда, которые адекватно отражают течение процесса или явления, задаваемого этим рядом. Поиск типичных подпоследовательностей дает возможность резюмировать и визуализировать большие временные ряды в широком спектре приложений: мониторинг технического состояния сложных машин и механизмов, интеллектуальное управление системами жизнеобеспечения, мониторинг показателей функциональной диагностики организма человека и др. Предложенная недавно концепция сниппета формализует типичную подпоследовательность временного ряда следующим образом. Сниппет представляет собой подпоследовательность, на которую похожи многие другие подпоследовательности данного ряда в смысле специализированной меры схожести, основанной на евклидовом расстоянии. Поиск типичных подпоследовательностей с помощью сниппетов показывает адекватные результаты для временных рядов из широкого спектра предметных областей, однако соответствующий алгоритм имеет высокую вычислительную сложность. В настоящей работе предложен новый параллельный алгоритм поиска сниппетов во временном ряде на графическом ускорителе. Распараллеливание выполнено с помощью технологии программирования CUDA. Разработаны структуры данных, позволяющие эффективно распараллелить вычисления на графическом процессоре. Представлены результаты вычислительных экспериментов, подтверждающих высокую производительность разработанного алгоритма.

Discovery of typical subsequences in a time series is one of the topical problems of time series mining. In this problem, we are to find a set of subsequences that adequately represents the specified time series. The solution of such a problem makes it possible to summarize and visualize a large time series in a wide range of applications: monitoring of the technical condition of complex machines and mechanisms, intelligent management of life support systems, monitoring of indicators of functional diagnostics of the human body, etc. The recently proposed snippet concept formalizes a typical time series subsequence as follows. A snippet of a time series is a subsequence that many other subsequences of the given series are similar to, with respect to a specialized similarity measure based on the Euclidean distance. Despite the snippets discovery algorithm shows adequate results for time series from a wide range of subject domains, it has a high computational complexity. In this article, we propose a novel parallel algorithm for snippets discovery on GPU. Parallelization is performed through the CUDA programming technology. We developed data structures that allow for efficient parallelization of GPU calculations. The experimental results show the high performance of the proposed algorithm.
Four Samaritan Menorahs from the village of Hajjeh, Samaria
Authors: Erlich Ze’ev H. (Zhabo) , Rotter Meir
Published: December 2021

This paper describes the authors’ discovery of four ancient menorahs inscribed on stone in the village of Hajjeh, Samaria. These four menorahs join another previously menorah discovered in Hajjeh, which has been published by Yuval Peleg in the past, bringing the total number of menorahs we know about in this village to five. This paper combines analyses of the known history of Hajjeh with the rich finds from the ancient inscribed menorahs. These analyses, together with information from historical sources on the village and its surroundings during the Byzantine and early Islamic periods, expand our knowledge about the locality and the use of ancient menorahs inscribed on stone during the Roman and Byzantine periods.
Quantification of gas-accessible microporosity in metal-organic framework glasses

Published: December 2021

Metal-organic framework (MOF) glasses are a new class of microporous glass materials with immense potential for applications ranging from gas separation to optics and solid electrolytes. Due to the inherent difficulty to determine the atomistic structure of amorphous glasses, the intrinsic structural porosity of MOF glasses is only poorly understood. In this work, the porosity features of a series of prototypical MOF glass formers from the family of zeolitic imidazolate frameworks (ZIFs) and their corresponding glasses is investigated comprehensively. CO2 gas sorption at 195 K allows to follow the evolution of microporosity when transforming from the crystalline to the glassy state of these materials. Based on these data, the pore volume and the real density of the ZIF glasses is quantified for the first time. Additional hydrocarbon sorption data (n-butane, propane and propylene) together with X-ray total scattering experiments prove that the porosity features (in particular the pore size and the pore limiting diameter) of the ZIF glasses depend on the types of organic linkers present in the glass network. This allows formulating first design principles for a targeted tuning of the intrinsic microporosity of MOF glasses. Importantly, these principles are counterintuitive and contrary to established porosity design concepts for crystalline MOFs but show similarities to strategies previously developed for porous polymers.

Published: December 2021

Passive permeability of a drug-like molecule is a critical assay early in a drug discovery campaign that informs a medicinal chemist how well a compound can traverse biological membranes, such as gastrointestinal epithelial or restrictive organ barriers, so it can perform a specific therapeutic function. However, the challenge that remains is the development of a method, experimental or computational, which can both determine the permeation rate and provide mechanistic insights into the transport process to help with the rational design for any given molecule. Typically, one of three methods are used to measure membrane permeability: (1) experimental permeation assays acting on either artificial or natural membranes; (2) quantitative structure-permeability relationship (QSPR) models that rely on experimental values of permeability or related pharmacokinetic properties of a range of molecules to infer those for new molecules; (3) estimates of permeability from the Smoluchowski equation, where free energy and diffusion profiles along the membrane normal are taken as input from large-scale molecular dynamics simulations. While all these methods provide estimates of permeation coefficients, they provide very little information for guiding rational drug design. In this study, we employ a highly parallelizable weighted ensemble (WE) path sampling strategy, empowered by cloud computing techniques, to generate unbiased permeation pathways and permeability coefficients for a set of drug-like molecules across a neat 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphatidylcholine (POPC) membrane bilayer. Our WE method predicts permeability coefficients that compare well to experimental values from an MDCK-LE cell line and PAMPA assays for a set of drug-like amines of varying size, shape, and flexibility. Our method also yields a series of continuous permeation pathways weighted and ranked by their associated probabilities. Taken together, the ensemble of reactive permeation pathways, along with the estimate of the permeability coefficient, provides a clearer picture of the microscopic underpinnings of small molecule membrane permeation.
Boomerang Kids in the Pandemic: How High-Income Families Are Their Own Safety Net
Authors: Widra Rachel , Luduvice André Victor D.
Published: December 2021

In this Economic Commentary, we use the Current Population Survey to identify and examine the influx of young adults who moved in with their parents during the COVID-19 pandemic—the so-called boomerang kids—and how being in their family home influences their labor market decisions and sensitivity to occupational risk relative to that of other young adults. We find that most boomerang kids come from high-income families that can financially support them through nonemployment spells that are, on average, longer than those of young adults not living with their parents. Young adults living with their parents are also more responsive to the risk of COVID-19 exposure in the workplace and are less likely to work in occupations with high exposure risk.
