Spectrum sharing is of paramount importance in television white space (TVWS) wireless communications. Secondary users must ensure that their operation in any TV channel does not interfere with the transmission of the primary users and other secondary users. This paper presents a menu-driven interface (MDI) which a secondary user inquirer may utilize to determine the TV channels available. The MDI utilizes a reinforcement learning-based algorithm and an interference indicator to determine the availability of each TV channel for secondary use. The algorithm utilized a set of parameters to provide accurate data on the availability of the channel. These parameters include time, location, and the receiving antenna parameters. The algorithm was able to produce an accuracy of 94.69% in determining the availability of the channel based on the broadcasting time of primary users (PUs) and an accuracy of 84.38% based on four tested locations.

Zapraszając Państwa do lektury drugiego numeru roku 2021 rozpoczynamy od słów pożegnania Prof. dr. hab. Józefa Półturzyckiego, który 25.08.2021 roku odszedł na wieczny spoczynek. Profesor dla polskiej andragogiki jest postacią wyjątkową. Można powiedzieć, że stworzył środowisko andragogiczne w Polsce. Był inicjatorem powołania do życia Akademickiego Towarzystwa Andragogicz- nego, jego pierwszym prezesem, a później honorowym prezesem. Przyczynił się do powstania czasopism ATA – przede wszystkim czasopisma „Rocznik Andragogiczny”, w którym był pierwszym i wieloletnim redaktorem naczelnym oraz współuczestniczył, wraz z prof. Anną Wesołowską, w powołaniu naszego pisma „Edukacja Dorosłych”. Profesor Józef Półturzycki był zaangażowany w powsta- nie Letniej Szkoły Młodych Andragogów, był współorganizatorem Toruńskich Konferencji Andragogicznych oraz pomysłodawcą Zakopiańskich Konferencji Andragogicznych, nawiązał też współpracę z Niemieckim Towarzystwem Uniwer- sytetów Ludowych (DVV – przedstawicielstwo w Polsce). To tylko kilka przykła- dów z bogatej aktywności Profesora na rzecz zintegrowania środowiska polskich andragogów. Oczywiście, jest Autorem bardzo wielu publikacji andragogicznych, których w tym miejscu nie będę przywoływała. Szczegółowo pisze o nich Monika Gromadzka w niniejszym wydaniu „Edukacji Dorosłych”, w artykule, od którego rozpoczynamy aktualny numer.

W artykule podjęto problematykę przekładu pieśni na podstawie pięciu utworów Michała Glinki do słów Nestora Kukolnika. Ten typ przekładu wymaga od tłumacza dostosowania tekstu do melodii – uwzględnienia m.in. liczby sylab, rozłożenia akcentów, cezur. Pieśni przeanalizowano pod kątem zachowania ekwiwalencji pragmatycznej, którą na potrzeby artykułu zdefiniowano jako relację opartą na funkcjonalności tekstu w kulturze docelowej, z możliwością jego zaśpiewania.
A General Branch-and-Cut Framework for Rotating Workforce Scheduling
Authors: Becker Tristan , Schiffer Maximilian , Walther Grit
Published: February 2022

In this paper, we propose a general algorithmic framework for rotating workforce scheduling. We develop a graph representation that allows to model a schedule as a Eulerian cycle of stints, which we then use to derive a problem formulation that is compact toward the number of employees. We develop a general branch-and-cut framework that solves rotating workforce scheduling in its basic variant, as well as several additional problem variants that are relevant in practice. These variants comprise, among others, objectives for the maximization of free weekends and the minimization of employees. Our computational studies show that the developed framework constitutes a new state of the art for rotating workforce scheduling. For the first time, we solve all 6,000 instances of the status quo benchmark for rotating workforce scheduling to optimality with an average computational time of 0.07 seconds and a maximum computational time of 2.53 seconds. These results reduce average computational times by more than 99% compared with existing methods. Our algorithmic framework shows consistent computational performance, which is robust across all studied problem variants.

Summary of Contribution: This paper proposes a novel exact algorithmic framework for the well-known rotating workforce scheduling problem (RWSP). Although the RWSP has been extensively studied in different problem variants and for different exact and heuristic solution approaches, the presented algorithmic framework constitutes a new state-of-the-art for the RWSP that solves all known benchmark sets to optimality and improves on the current state-of-the-art by orders of magnitude with respect to computational times, especially for large-scale instances. The paper is both of methodological value for researchers and of high interest for practitioners. For researchers, the presented framework is amenable for various problem variants and provides a common ground for further studies and research. For practitioners and software developers, low computational times of a few seconds allows the framework to be to embedded into personnel scheduling software.
Types of Consumer Operant Resources and Co-creation in Dialogical Service Relationships
Authors: Tarı Kasnakoğlu Berna , Kalender Yunus , Gökkaya Hatice
Published: February 2022

This study investigates different types of operant resources and their effects on cocreation by considering the moderation effects of cocreation potential and the provider’s positive attitude. The contextual nature of operant resources is discussed based on how consumers activate resources in different service situations. The first study explores whether context-specific resources contribute to cocreation more than general resources. This hypothesis is found to be valid only for certain service contexts. In-depth interviews are conducted in the second study to understand the phenomenon more deeply. The qualitative study reveals three distinct types of resources: general, context-specific, and interpersonal resources. In the third study, a scenario-based experimental study is conducted to test the hypotheses, which are confirmed. We conclude that context-specific resources more directly shape cocreation, moderated by perceived level of cocreation potential. The relationship between potential and resources is then moderated by the provider’s positive attitude.
Knowledge of health rights and community participation in primary care
Authors: Agegnehu Wubetu , Derese Msganaw , Genetu Amare , Hailemariam Shewangizaw
Published: February 2022

Background/Aims

Primary care providers are encouraged to promote community participation in care, so that patients are engaged in health priorities and solutions. This study assessed the level of knowledge regarding health rights and community participation in a town in Mizan-Aman, Ethiopia.

Methods

A community-based cross-sectional study design was used. A structured questionnaire was administered to 374 community health leaders assessing their knowledge of health rights and the level of community participation in primary care, according to five indicators: leadership, organisation, management, resource mobilisation and needs assessment.

Results

A total of 326 out of 374 questionnaires were returned. The majority (n=205, 62.9%) had limited knowledge of health rights, while 189 (58%) indicated poor community participation in primary healthcare. There was no significant association between knowledge of health rights and level of community participation.

Conclusions

Knowledge of health rights is generally lacking in these communities, as is public participation in primary care service planning. A community-based health education programme is needed to raise awareness of patient rights and enhance community participation in primary care.
Oesophagostomy: a rare and complex clinical challenge—the vital role of the stoma care nurse specialist
Authors: Power Sally , Stopher Sharon
Published: February 2022

An oesophagostomy is a rare stoma not commonly encountered by clinical nurse specialists. When a patient presented with a spontaneous rupture of the oesophagus (Boerhaave's syndrome) the stoma care team are presented with many challenges including finding a suitable appliance to contain the amount of saliva produced; teaching the patient to be independent with his stoma care and assisting the patient to cope with the changes to his body image. In this article, Sally Power and Sharon Stopher identify why oesophagostomies are undertaken and how the stoma care nurse must work in partnership with the patient and other members of the multidisciplinary team, to manage this type of stoma in a way that enhances the patients quality of life.
Acute onset low back pain leading to a diagnosis of cauda equina syndrome: a case study
Authors: Read Haley , Mortimore Gerri
Published: February 2022

Cauda equina syndrome is rarely seen in primary care, but advanced practitioners must be aware of the possibility. Haley Read and Gerri Mortimore highlight a case study leading to a diagnosis of the condition

One of the most common symptoms managed in primary care is lower back pain, which affects approximately 20% of the UK population at any one time ( National Collaborating Centre for Primary Care, 2009 ). There are many differential diagnoses for the cause of back pain, with one such potential diagnosis being cauda equina syndrome. In this instance, it is of paramount importance that the correct diagnosis is reached quickly with urgent referral into secondary care for the instigation of treatment to prevent paralysis. This case review will examine a patient presenting to primary care with lower back pain and diagnosed with cauda equina syndrome.

Downlink measurement campaigns from the optical downlink terminal OSIRISv1 onboard the LEO satellite Flying Laptop were carried out with the French Observatoire de la Côte d’Azur and with two Optical Ground Stations of the German Aerospace Center. On/off keyed data at 39 Mb/s were modulated on the laser signal, and according telecom reception was performed by the ground stations. The pointing of the laser terminal was achieved by open-loop body pointing of the satellite orientation, with its star sensor as attitude control signal. We report here on the measurements and investigations of the downlink signal and the data transmission.
Real-time image denoising of mixed Poisson–Gaussian noise in fluorescence microscopy images using ImageJ

Published: February 2022

Fluorescence microscopy imaging speed is fundamentally limited by the measurement signal-to-noise ratio (SNR). To improve image SNR for a given image acquisition rate, computational denoising techniques can be used to suppress noise. However, common techniques to estimate a denoised image from a single frame either are computationally expensive or rely on simple noise statistical models. These models assume Poisson or Gaussian noise statistics, which are not appropriate for many fluorescence microscopy applications that contain quantum shot noise and electronic Johnson–Nyquist noise, therefore a mixture of Poisson and Gaussian noise. In this paper, we show convolutional neural networks (CNNs) trained on mixed Poisson and Gaussian noise images to overcome the limitations of existing image denoising methods. The trained CNN is presented as an open-source ImageJ plugin that performs real-time image denoising (within tens of milliseconds) with superior performance (SNR improvement) compared to conventional fluorescence microscopy denoising methods. The method is validated on external datasets with out-of-distribution noise, contrast, structure, and imaging modalities from the training data and consistently achieves high-performance (

Published: February 2022

Aspherical- and multi-curve rigid gas-permeable hard contact lenses (HCLs) have a flattened curve in the peripheral zone and are mostly used for patients with keratoconus who cannot wear glasses, soft contact lenses, or spherical HCLs. In this retrospective study, a total of 95 eyes of 77 patients who used aspherical- or multi-curve HCLs (mean age: 40.0 ± 11.0 years) were evaluated. This study examined the types of aspherical- and multi-curve HCLs, best-corrected visual acuity (BCVA) values before and after wearing HCLs, the association with the Amsler-Krumeich classification, duration of wear, corneal/conjunctival disorder, and the frequency of changing HCLs. There were 78 eyes that used aspherical-curve HCLs and 17 that used multi-curve HCLs. BCVA significantly improved from 0.42 logMAR to 0.06 logMAR after wearing either form of HCL. The Amsler-Krumeich classification showed that aspherical-curve HCLs were commonly used for patients with stage 2 keratoconus, and multi-curve HCLs were commonly used for stage 4 patients. The BCVA values were worse when the disease stage was more severe (stages 3 and 4) regardless of HCL type. The mean base curve of the lenses was steeper in multi-curve HCLs than in aspherical-curve HCLs. The more severe the disease stage, the steeper the base curve in both aspherical- and multi-curve HCLs. The duration of wear significantly improved from 2.1 h to 10.2 h, and corneal/conjunctival disorder similarly improved. The mean frequency of changing HCL types was 1.1 times. This study suggests that a flat peripheral curve design with aspherical- and multi-curve HCLs is useful for patients with keratoconus.
The impact of risk perceptions and belief in conspiracy theories on COVID-19 pandemic-related behaviours

Published: February 2022

Throughout the COVID-19 pandemic, conspiracy theories about the virus spread rapidly, and whilst governments across the globe put in place different restrictions and guidelines to contain the pandemic, these were not universally adhered to. This research examined the association between pandemic related risk perceptions, belief in conspiracy theories, and compliance with COVID-19 public guidelines amongst a UK sample (n= 368). Participants rated their level of concern for a series of potential risks during the pandemic (to the economy, personal health, freedom, media integrity and health risk to others). Participants also rated their level of belief in different conspiracy theories and self-reported their behaviour during the first UK lockdown. Mediational analyses showed that stronger belief in conspiracy theories was associated with perceptions of lower risk to health and higher risk to the economy and freedom, which in turn were associated with lower compliance with COVID-19 related governmental guidelines. Perception of information transparency risks did not mediate the association between belief in conspiracy theories and compliant behaviours. These results highlight the key role that risk perception may play in translating belief in conspiracy theories into low compliance with governmental COVID-19 related guidelines. Our findings suggest new patterns with respect to the relationship between conspiracy theory adherence and salience of different risk perceptions amidst the pandemic, which could have implications for the development of public health messaging and communication interventions.
The social impacts of information and communication technology on sustainable development
Authors: Alhassan Muftawu Dzang , Adam Ibrahim Osman
Published: February 2022

In this study, we examine the empirical relationship between information and communication technology (ICT) development and sustainable development and explore whether the social impacts of ICTs can play a mediating role in this linkage. Given the concentration of previous literature on the effects of ICT use on sustainable development, there exists a gap in the linkage between ICT development, social impacts of ICTs, and sustainable development. Drawing on data from secondary sources from 143 countries globally for 2016, we validate a hypothesized model based on the capabilities approach and structural equation modelling to examine these linkages. Our findings show that ICT development through ICT access has a dual role on sustainable development. First, by spurring sustainable development directly and indirectly when the social impacts of ICTs act as a mediator. We provide some implications for practice and policy.

Diagnostic Evaluation of Gastric Motor and Sensory Disorders

Published: February 2022

Abstract: Disorders of gastric motor and sensory function affect 10%-20% of the world’s population and adversely impact nutrition, quality of life, work productivity, and health care costs. Classifying these disorders can be challenging given the heterogeneity of symptom presentation, the presence of symptoms unexplained by endoscopic, radiographic and/or laboratory evaluation, and overlap with other luminal gastrointestinal disorders. Accurately diagnosing these highly prevalent disorders relies upon an understanding of epidemiology and risk factors, the ability to take a careful clinical history focused on symptoms, and the presence of predisposing medical, surgical, and psychological conditions. A variety of diagnostic studies are now available to assess gastric motor function and identify maladaptive relaxation, accommodation, and abnormal sensation. FDA-approved treatment options are limited and thus many patients undergo a series of empirical treatment trials that target individual symptoms, often without much benefit. This article provides updated recommendations for identifying and classifying the most common gastric motor and sensory disorders using currently accepted diagnostic tests, and provides a brief supplemental overview on treatment options. “Things sweet to taste prove in digestion sour.” –Shakespeare, Richard II, 1595.
Regulation on Genetically Modified Animals: Proposed and Its Possible Application in Indonesia
Authors: Tiesnamurti Bess , Muharsini Sri , Shiddieqy M I
Published: February 2022

The government is responsible for fulfil the needs of safe, healthy and halal food for all its people in a sustainable manner. The world population will increase from 7 to 9 billion people in 2050. While the availability of land may not increase in the future, it may even not be used for agriculture. Scientists are trying to overcome this problem by creating technologies that can increase livestock productivity, one of which is through a genetically modified process. Genetically modified animals are animals that have been genetically modified for many  purposes including yields and disease resistance. Although genetically modified animals are at the last stage of research and the possibility to entering Indonesia remains small, but government should prepare a regulation related to it. European countries and USA have regulations to control genetically modified animals. Malaysia also has applied a similar regulation since 2007. Currently, Indonesia has formed an authority that oversees the genetically modified product, namely Biosafety Commission (Komisi Keamanan Hayati) on genetically modified products. However, this commission only supervises genetically modified organism in food and feed. This paper is aimed to propose the regulation for genetically modified animal that may be entering Indonesia and or be researched by Indonesian scientists.
Historiografia e Negação do Holocausto: o caso Lipstadt vs. Irving
Authors: Soares de Brito Wallace Guilherme
Published: February 2022

Este trabalho tem como objetivo elaborar uma interface entre filosofia e cinema a partir de uma análise temática do filme "Negação" (2016) sob o viés do verbete Filosofia da História de Daniel Little (2016); o que faremos através de uma síntese da trama que envolve dois escritores: a professora Deborah Lipstadt, historiadora; e David Irving, autor negacionista do Holocausto. Utilizaremos como fontes a obra Negação, da Professora Lipstadt, bem como o bestseller Hitler’s War (1977), do Irving. Focaremos nos argumentos apresentados por Irving, quais sejam: Hitler não sabia da “Solução Final”, e quando soube tentou evitá-la; nenhuma pessoa foi executada nos campos de extermínio nazistas e, por fim, o que conhecemos como Holocausto não aconteceu. Os compararemos com três conceitos desenvolvidos por Little (2016) em seu verbete mencionado: o papel do historiador, os critérios de verificação que atestam suas "verdades" e a possibilidade de neutralidade na pesquisa, analisando o filme à luz da obra de ambos os autores. Concluímos que Irving se distancia do viés História da Filosofia e que sua argumentação é baseada em deturpações de documentos históricos, especulações infundadas e sua vontade pessoal de que fosse verdade.

Historiography and Holocaust Denial: The Case Lipstadt vs. Irving
 
Abstract: This work aims to elaborate an interface between historiography and cinematography based on a thematic analysis of the film "Negação" (2016) under the bias of the entry Philosophy of History by Daniel Little (2016); what we will do through a synthesis of the plot that involves two writers: professor Deborah Lipstadt, historian; and David Irving, author and Holocaust denialist. We will use as sources the book Negação (2017), by Professor Lipstadt, as well as the bestseller Hitler’s War (1977), by Irving. We will focus on the arguments presented by Irving, namely: Hitler did not know about the “Final Solution”, and when he did he tried to avoid it; no one was executed in the Nazi death camps and, finally, what we know as the Holocaust did not happen. We will compare them with three concepts developed by Little (2016) in his mentioned entry: the role of the historian, the verification criteria that attest to his "truths" and the possibility of neutrality in the research, analyzing the film in the light of the work of both authors . We conclude that Irving distances himself from the History of Philosophy bias and that his argument is based on misrepresentations of historical documents, unfounded speculations and his personal desire for it to be true.

Porque devemos desconfiar da intuição repugnante
Authors: Figueredo André Luis Lindquist
Published: February 2022

Resumo: A Conclusão Repugnante é a afirmação, proposta por Derek Parfit (1984, p. 388), de que uma população de pelo menos 10 bilhões de pessoas vivendo vidas muito boas é, se todas as outras coisas forem iguais, pior do que uma população suficientemente maior de pessoas vivendo vidas muito ruins. Neste artigo, pretendo mostrar porque devemos desconfiar da intuição, que muitos de nós temos, de que a Conclusão Repugnante é obviamente falsa. Primeiro, seguindo por um lado Broome (2004) e por outro Gustafsson (no prelo), defendo que devemos desconfiar dessa intuição “repugnante” porque ela exige que imaginemos quantidades extraordinariamente grandes de números e, por consequência, nós as imaginamos de maneira inexata. Depois, objeto duas maneiras de se argumentar contra este ceticismo sobre a veracidade de intuições que exigem imaginarmos quantidades numéricas extraordinariamente grandes, uma proposta por Temkin (2012) e outra por Pummer (2013). Por fim, como a solidez de ambas as maneiras de argumentar depende de que sejamos capazes de decidir a verdade aparente de proposições modais que, seguindo o ceticismo modal de Inwagen (1998), não conseguimos decidir, pois afirmam a possibilidade metafísica de entes extraordinários existirem, concluo que devemos manter nossa desconfiança sobre a intuição repugnante.

Why we should distrust the repugnant intuition
Abstract: The Repugnant Conclusion is the claim, proposed by Derek Parfit (1984, p. 388), that a population of at least 10 billion people living very good lives is, if other things are equal, worse than a sufficiently large population of people living very bad lives. In this article, I aim to show why we should distrust the intuition we might have that the Repugnant Conclusion is obviously false. First, following Broome (2004) in a way and Gustfasson (forthcoming) in another, I argue that we should distrust this “repugnant” intuition because it demands that we imagine extraordinarily large quantities and, by consequence, we imagine them inexactly. Afterward, I object against two modes of arguing against this skepticism about the veracity of intuitions which demands that we imagine extraordinarily large quantities of numbers, one proposed by Temkin (2012) and the other by Pummer (2013). Finally, since the soundness of both modes depends on wether we are capable of deciding the truth of modal propositions that, following the modal skepticism of Inwagen (1998), we cannot decide, for they state that it’s metaphysically possible that extraordinary beings exist, I conclude that we should maintain our distrust towards the repugant conclusion.

Модели стохастической динамики развития производственных предприятий с запаздывающими внутренними и внешними инвестициями
Authors: Сараев Александр Леонидович , Saraev Aleksandr Leonidovich , Сараев Леонид Александрович , Saraev Leonid Alexandrovich
Published: February 2022

Предложены новые стохастические модели динамического развития предприятий, которые восстанавливают свои производства за счет внутренних и внешних запаздывающих инвестиций. Установлены системы стохастических дифференциальных уравнений баланса для таких предприятий, описывающие случайные изменения факторов производства и выпуска продукции. Рассмотрены пропорциональные, прогрессивные и дигрессивные амортизационные отчисления и исследовано их взаимодействие с запаздывающими внутренними и внешними инвестициями. Сформулированы условия достижения равновесного состояния работы предприятий и вычислены соответствующие предельные значения факторов производства. Для численных решений систем стохастических дифференциальных уравнений развития предприятий получены алгоритмы метода Эйлера—Маруямы. Для каждой численной реализации этих алгоритмов построены соответствующие стохастические траектории для случайных функций факторов производства и выпуска продукции. Предложен вариант метода расчета математических ожиданий случайных функций факторов производства, для которых получена соответствующая система дифференциальных уравнений. Численный анализ решений стохастических дифференциальных уравнений для разработанных моделей показал хорошее соответствие известным статистическим данным развития производственных предприятий.

Рассматривается задача математического моделирования процесса идентификации коэффициентов уравнения в частных производных в моделях конвективно-диффузионного переноса по результатам зашумленных измерений значений искомой функции с применением нового метода, относящегося к классу рекуррентных методов параметрической идентификации на основе алгоритмов оптимальной дискретной фильтрации калмановского типа.
Рассматриваются одномерные модели с постоянными коэффициентами, граничными условиями первого рода или смешанными граничными условиями первого и третьего рода.
Предлагаемый метод решения задачи основан на переходе от исходной непрерывной модели с уравнением в частных производных к модели, описываемой линейной дискретной динамической системой в пространстве состояний, и применении к ней метода максимального правдоподобия с построением критерия идентификации (функции правдоподобия) на основе величин, вычисляемых SVD-модификацией фильтра Калмана.
Данный фильтр основан на сингулярном разложении ковариационной матрицы ошибок оценивания вектора состояния и устойчиво работает даже в тех случаях, когда она близка к вырожденной.
SVD-фильтр хорошо зарекомендовал себя при решении различных задач дискретной фильтрации и параметрической идентификации и обладает целым рядом преимуществ по сравнению с традиционно используемым стандартным фильтром Калмана, главным из которых является устойчивость к ошибкам машинного округления.
Приводятся результаты компьютерного моделирования процессов параметрической идентификации в системе MATLAB с использованием специализированного программного комплекса.
Результаты численных экспериментов подтверждают работоспособность предложенного метода и его преимущества по сравнению с аналогичным методом на основе стандартного фильтра Калмана.
Пластическое течение и ползучесть в полом цилиндре с жестким внешним покрытием под действием внутреннего давления
Authors: Фирсов Сергей Викторович , Firsov Sergey Viktorovich
Published: February 2022

Изучается изотермическое деформирование толстостенной трубы с жестким покрытием боковой поверхности под воздействием изменяющегося внутреннего давления. Рассматриваются четыре стадии нагружения: (1) плавный рост нагрузки, (2) ее фиксация на максимальном значении в течение продолжительного времени, (3) плавное уменьшение нагрузки до нуля и (4) частичная релаксация напряжений. В качестве материала взята сталь 45, разогретая до температуры 725 \textcelsius.
Изучается влияние ползучести на процесс пластического течения и на изменение уровня напряжений и деформаций в течение процесса деформирования, а также на их остаточные значения. Для изучения влияния ползучести также рассматривается задача деформирования с нулевыми скоростями ползучести. Рассматриваются два варианта нагружения: при распространении пластичности на часть среды (давление 200 МПа) и при распространении пластического течения на всю среду (давление 320 МПа при отсутствии ползучести).
По результатам расчетов получено, что ползучесть оказывает значительное влияние на распределение напряжений и деформаций в материале. Особенно сильно это проявляется на более продолжительных стадиях выдержки и релаксации. Расчеты для двух случаев нагружения давлением в 200 МПа и 320 МПа в конце стадии выдержки приводят к близким значениям напряжений, а после релаксации также сравниваются значения деформаций и перемещения. При сравнении случаев упругопластического деформирования и деформирования с учетом ползучести видим, что ползучесть замедляет распространение пластичности, а также сокращает итоговую область влияния пластического течения. Однако в связи с большими накопленными необратимыми деформациями ползучесть приводит к увеличению влияния повторного пластического течения, которое появляется раньше и затрагивает большую часть деформируемой среды.
“All schools are not created equal:” An analysis of public comments on school rezoning
Authors: Castro Andrene J. , Parry Mitchell , Siegel-Hawley Genevieve
Published: February 2022

Public opinion plays an important role in shaping the policy process. We examined public input in the form of written public comments to interrogate group expression and public values in school policymaking. Drawing on theoretical and methodological tenets of critical policy and critical discourse analysis, our study examined 3,339 written public comments across two school districts undergoing school rezoning, which is the process of drawing and redrawing school attendance boundaries. Our findings highlight the complexity of public opinion on rezoning policies related to 1) competing values and visions for school diversity, 2) racialized conceptualizations of community members’ sense of belonging, and 3) forms of boundary maintenance used to discursively resist boundary changes by excluding students and families of color from crucial resources. As more U.S. districts consider rezoning to balance the racial and/or economic composition of schools, this study contributes new insight into stakeholders’ implicit and explicit racial attitudes, motivations, and values in response to rezoning’s complex policy process.
Comparison of the effect of silicone gel sheets by thickness on excisional scars in pediatric and adolescent patients
Authors: Kim Min Ji , Lee Woo Beom , Park Dong Ha
Published: February 2022

Background Selecting effective products among the various types of silicone gel sheets can be challenging for surgeons. Therefore, we assessed the effect of silicone gel sheet thickness on surgical scars in pediatric and adolescent patients.Methods From December 2017 to May 2018, we identified patients aged 1–19 years who underwent excision. Among these patients, those who were prescribed 0.3-mm or 1.0-mm-thick silicone sheets were selected. Scars were subjectively evaluated using a questionnaire consisting of seven items. Objective evaluation was performed by two plastic surgeons using the Vancouver Scar Scale (VSS).Results The mean age of the 49 selected patients was 9.78 years. The patients were divided into two groups according to the thickness of the silicone gel sheet used (0.3 mm vs. 1.0 mm). Objective evaluation of the patients’ scars revealed more favorable results in the 0.3 mm group than in the 1.0 mm group (P=0.010). Multivariate analysis of VSS scores indicated that the resulting scars in cases involving the trunk were of poorer quality than those involving facial areas (P=0.015). Additionally, favorable (i.e., below-average) VSS scores were significantly less likely in patients with longer scars (odds ratio, 0.896; 95% confidence interval, 0.834–0.963; P=0.003) or thicker silicone sheets (odds ratio, 0.085; 95% confidence interval, 0.011–0.699; P=0.019).Conclusions The use of thinner silicone gel sheets in children and adolescents resulted in better scars according to subjective evaluations, underscoring the importance of compliance in pediatric patients. The type of operation and surgical lesion should also be considered when planning the management of surgical scars.
Locoregional flaps versus skin grafts in the nose: aesthetic considerations after cancer ablation
Authors: Yoon Sihyun , Kim Youngjun , Choi Youngwoong
Published: February 2022

Background The annual incidence of skin cancer has been increasing, and surgical ablation is presently the treatment of choice for skin cancer. However, it leaves soft tissue defects that require reconstruction. The methods for reconstruction include locoregional flaps (LRFs) and full-thickness skin grafts (FTSGs). We compared these two surgical methods for reconstruction of defects in the nose, which is prominently visible and the most common site of facial skin cancer, and assessed the cosmetic results by evaluating the scars.Methods This retrospective study was conducted between July 2012 and January 2021. Patients were evaluated for scars after at least 6 months of follow-up. Patients were divided into LRF and FTSG groups. The scars were evaluated using the Vancouver Scar Scale.Results In total, 27 patients were included in this study. Their mean age was 66.8 years. Eighteen patients underwent LRF, and nine patients underwent FTSG. The average defect size was 1.55 cm² in the LRF group, and 1.38 cm² in the FTSG group. The average scar score was 1.44 points in the LRF group and 3.67 points in the FTSG group. The LRF group showed significantly lower total scores than the FTSG group.Conclusions Although LRFs and FTSGs are useful reconstructive methods for nasal soft tissue defects, this study showed that LRFs are superior to FTSGs in terms of aesthetic results.
Comparison of kriging and least-squares collocation – Revisited
Authors: Ligas Marcin
Published: February 2022

The well-known to physical geodesists method of least-squares collocation and the geostatistical method of kriging probably known to the broader audience are compared. Both methods are rooted in Wiener–Kolmogorov’s (W–K) prediction theory; but, since necessity is the mother of invention, the W–K foundations have been extended to satisfy the needs of particular applications. The paper presents a link or rather an equivalence of the two methods as far as their basic forms are considered (specialization to geodetic boundary-value problems, covariance propagation between functionals and nonlinear geostatistical methods are excluded from this comparison). Only scalar random fields (univariate case) and the assumption of a second-order structure of a random function are considered. Due to the equivalence of their basic formulas, both techniques share the same advantages and disadvantages. The paper also shows the difference as to the predicted values and prediction variances in case of exact and filtered (noise reduction) prediction models. This theoretical comparison of the methods has practical implications because of readily available geostatistical software that, in local as well as global applications, can be used for predictive problems occurring in geodesy and surveying.

Sharp function estimates and boundedness for Toeplitz-type operators associated with general fractional integral operators
Authors: Chen Dazhao , Huang Hui
Published: February 2022

In this paper, we establish some sharp maximal function estimates for certain Toeplitz-type operators associated with some fractional integral operators with general kernel. As an application, we obtain the boundedness of the Toeplitz-type operators on the Lebesgue, Morrey and Triebel-Lizorkin spaces. The operators include the Littlewood-Paley operator, Marcinkiewicz operator and Bochner-Riesz operator.
Poly-falling factorial sequences and poly-rising factorial sequences
Authors: Kim Hye Kyung
Published: February 2022

In this paper, we introduce generalizations of rising factorials and falling factorials, respectively, and study their relations with the well-known Stirling numbers, Lah numbers, and so on. The first stage is to define poly-falling factorial sequences in terms of the polyexponential functions, reducing them to falling factorials if

k
=

k=1

, necessitating a demonstration of the relations: between poly-falling factorial sequences and the Stirling numbers of the first and second kind, respectively; between poly-falling factorial sequences and the poly-Bell polynomials; between poly-falling factorial sequences and the poly-Bernoulli numbers; between poly-falling factorial sequences and poly-Genocchi numbers; and recurrence formula of these sequences. The later part of the paper deals with poly-rising factorial sequences in terms of the polyexponential functions, reducing them to rising factorial if

k
=

k=1

. We study some relations: between poly-falling factorial sequences and poly-rising factorial sequences; between poly-rising factorial sequences and the Stirling numbers of the first kind and the power of

; and between poly-rising factorial sequences and Lah numbers and the poly-falling factorial sequences. We also derive recurrence formula of these sequences and reciprocal formula of the poly-falling factorial sequences.
