Background & objectives:

The global pandemic caused by SARS-CoV-2 virus has challenged public health system worldwide due to the unavailability of approved preventive and therapeutic options. Identification of neutralizing antibodies (NAb) and understanding their role is important. However, the data on kinetics of NAb response among COVID-19 patients are unclear. To understand the NAb response in COVID-19 patients, we compared the findings of microneutralization test (MNT) and plaque reduction neutralization test (PRNT) for the SARS-CoV-2. Further, the kinetics of NAb response among COVID-19 patients was assessed.

Methods:

A total of 343 blood samples (89 positive, 58 negative for SARS-CoV-2 and 17 cross-reactive and 179 serum from healthy individuals) were collected and tested by MNT and PRNT. SARS-CoV-2 virus was prepared by propagating the virus in Vero CCL-81 cells. The intra-class correlation was calculated to assess the correlation between MNT and PRNT. The neutralizing endpoint as the reduction in the number of plaque count by 90 per cent (PRNT90) was also calculated.

Results:

The analysis of MNT and PRNT quantitative results indicated that the intra-class correlation was 0.520. Of the 89 confirmed COVID-19 patients, 64 (71.9%) showed NAb response.

Interpretation & conclusions:

The results of MNT and PRNT were specific with no cross-reactivity. In the early stages of infection, the NAb response was observed with variable antibody kinetics. The neutralization assays can be used for titration of NAb in recovered/vaccinated or infected COVID-19 patients.

Authors: Red'kin Nikolay Petrovich
Published: September 2020

В работе исследуется сложность реализации контактными схемами характеристических функций сфер. Под характеристической функцией сферы с центром в вершине $\tilde\sigma=(\sigma_1,\ldots,\sigma_n)$, $\sigma_1,\ldots,\sigma_n\in\{0,1\}$, подразумевается булева функция $\varphi^{(n)}_{\tilde\sigma}(x_1,\ldots,x_n)$, обращающаяся в единицу на всех тех и только тех наборах значений, каждый из которых отличается от набора $\tilde\sigma$ ровно в одном разряде. Устанавливается, что для реализации $\varphi^{(n)}_{\tilde\sigma}(\tilde x)$ контактной схемой необходимо и достаточно $3n-2$ контактов.
Эргодичность вероятностного преобразователя - последовательного соединения двух конечных автоматов
Authors: Kruglov Igor Aleksandrovich
Published: September 2020

В статье получены необходимые и достаточные условия эргодичности последовательного соединения автоматов, при котором выходная последовательность подстановочного автомата Мили поступает на вход подстановочного автомата без выхода. Показано, что условие вполне неразложимости матрицы вероятностей переходов состояний автомата Мили является достаточным для эргодичности указанного вероятностного преобразователя как последовательного соединения автоматов. Показано, что в случае попарной перестановочности частичных функций перехода состояний автомата Мили условие эргодичности последовательного соединения равносильно эргодичности обоих исходных вероятностных преобразователей.
Свойства многотипных докритических ветвящихся процессов в случайной среде
Authors: Vatutin Vladimir Alekseevich , Dyakonova Elena Evgen'evna
Published: September 2020

Исследуются свойства докритического ветвящегося процесса в случайной среде с $p$ типами частиц, начальное число частиц различных типов в котором задается вектором $\mathbf{z}=(z_{1},\ldots,z_{p})$. В случае $p=1$ класс рассматриваемых нами процессов соответствует строго докритическим ветвящимся процессам в случайной среде с одним типом частиц. Доказано, что вероятность невырождения такого процесса к далекому моменту времени $n$ эквивалентна $C(\mathbf{z})\lambda ^{n}$, где параметры $\lambda\in (0,1)$ и $C(\mathbf{z})\in (0,\infty)$ явно описаны в терминах характеристик процесса. Показано также, что предельное при $n\rightarrow \infty $ распределение числа частиц различных типов в процессе в момент $n$ (при условии его невырождения к этому моменту) не зависит от чисел и типов частиц, существовавших в процессе в нулевой момент времени.
Значения весовой системы, отвечающей алгебре Ли $\mathfrak{sl}_2$, на полных двудольных графах
Authors: Zinova Polina Aleksandrovna
Published: September 2020

В теории Васильева инварианты узлов конечного порядка описываются в терминах весовых систем - функций на хордовых диаграммах, удовлетворяющих 4-членным соотношениям. В частности, весовая система сопоставляется крашеному многочлену Джонса. Ее легко описать в терминах алгебры Ли $\mathfrak{sl}_2$ (так называемая $\mathfrak{sl}_2$-весовая система), однако вычисление ее значения на конкретной хордовой диаграмме является вычислительно сложной задачей, и, как следствие, ее явные значения известны лишь для весьма узких семейств хордовых диаграмм.
В статье дана явная формула для значений $\mathfrak{sl}_2$-весовой системы на семействе хордовых диаграмм, состоящем из диаграмм, граф пересечений которых является полным двудольным с числом вершин в одной из долей не более трех.
Основным инструментом в вычислении является рекуррентное соотношение Чмутова-Варченко. Кроме того, мы выводим явные формулы для проекции на подпространство примитивных элементов вдоль пространства разложимых в подалгебрах Хопфа алгебры Хопфа графов, порожденных полными двудольными графами с числом вершин в одной из долей не более трех. Как результат мы вычисляем значения $\mathfrak{sl}_2$-весовой системы на проекциях хордовых диаграмм с такими графами пересечений. Полученные нами результаты подтверждают ряд гипотез С. К. Ландо о значениях $\mathfrak{sl}_2$-весовой системы на проекциях хордовых диаграмм на подпространство примитивных элементов.подпространство примитивных.
Функции от возмущeнных пар некоммутирующих сжатий
Authors: Aleksandrov Alexei Borisovich , Peller Vladimir Vsevolodovich
Published: September 2020

В этой работе изучаются функции $f(T,R)$ от пар некоммутирующих сжатий в гильбертовом пространстве и рассматривается задача, для каких функций $f$ имеют место оценки липшицевого типа в нормах Шаттена-фон Неймана. Оказывается, что если $f$ входит в класс Бесова $(B_{\infty,1}^1)_+(\mathbb{T}^2)$ аналитических функций в бидиске, то для функций $f(T,R)$ от пар необязательно коммутирующих сжатий $(T,R)$ имеют место оценки липшицевого типа в нормах Шаттена-фон Неймана $\mathbf{S}_p$ при $p\in[1,2]$. С другой стороны, мы покажем, что для функций $f$ из $(B_{\infty,1}^1)_+(\mathbb{T}^2)$ такие оценки липшицева типа невозможны при $p>2$, равно как и в операторной норме.

Published: September 2020

Изучаются меры на вещественном сепарабельном гильбертовом пространстве $E$, инвариантые относительно сдвигов на произвольные векторы пространства. Определено гильбертово пространство $\mathcal H$ комплекснозначных функций на пространстве $E$, квадратично интегрируемых по некоторой инвариантной относительно сдвигов мере $\lambda$. Определены математические ожидания операторов сдвига на случайные векторы, распределения которых задаются полугруппами (относительно свертки) гауссовских мер на пространстве $E$. Установлено, что такие математические ожидания образуют полугруппу самосопряженных сжатий в пространстве $\mathcal H$. Получен критерий сильной непрерывности таких полугрупп и исследованы свойства их генераторов, представляющих собой самосопряженные обобщения операторов Лапласа на случай функций бесконечномерного аргумента. Введены аналоги пространств Соболева и пространств гладких функций. Получены условия вложения и плотного вложения пространств гладких функций в пространства Соболева. Введенные функциональные пространства применены в задачах аппроксимации полугрупп математическими ожиданиями от случайных процессов. Изучены свойства рассматриваемых обобщений операторов Лапласа и их дробных степеней.

Published: September 2020

Исследуются решетки в новом классе локально компактных групп, а именно в локально про-$p$-полных группах Каца-Муди. Обнаруживается, что в случае ранга 2 кокомпактные решетки особенно хорошо себя ведут: при небольших ограничениях у кокомпактной решетки в таком пополнении нет элементов порядка $p$. Это утверждение является открытой гипотезой для пополнений Капраса-Реми-Ронана. С помощью этого утверждения и результатов И. Капдебоск и А. Томас классифицируются кокомпактные решетки, транзитивные на ребрах, и описывается кокомпактная решетка минимального кообъема.

Волновод с двойным пороговым резонансом на простом пороге
Authors: Nazarov Sergei Aleksandrovich
Published: September 2020

Пороговый резонанс, вызванный появлением на пороге непрерывного спектра почти стоячей волны - решения задачи, не затухающего, но стабилизирующегося на бесконечности, - провоцирует разнообразные аномалии дифракционной картины на околопороговых частотах. Примеры однократного порогового резонанса или его отсутствия очевидны. В статье впервые построен акустический (спектральная задача Неймана для оператора Лапласа) волновод специфической формы, у которого на пороге (простое собственное число модельной задачи на сечении цилиндрических выходов на бесконечность) имеется максимально возможное количество (две) линейно независимых почти стоячих волн. Обсуждаются проистекающие от этих волн эффекты в задаче рассеяния акустических волн.

О перенормировках в неперенормируемых теориях
Authors: Kazakov Dmitri Igorevich
Published: September 2020

Предложен новый взгляд на процедуру перенормировок в неперенормируемых теориях. Он основан на обычной процедуре BPHZ-$\mathcal R$-операции, которая одинаково применима в любой локальной квантовой теории поля независимо от перенормируемости. Ключевым моментом является замена мультипликативной перенормировки, применяемой в перенормируемых теориях, на операцию, при которой константа перенормировки зависит от импульсов, по которым происходит интегрирование в подграфах. При этом условие локальности контрчленов (в точности как в перенормируемых теориях) приводит к рекуррентным соотношениям, связывающим лидирующие, подлидирующие и т.д. ультрафиолетовые расходимости во всех порядках теории возмущений. Это позволяет получить обобщенные уравнения ренормгруппы для амплитуд рассеяния, которые имеют интегро-дифференциальный вид и приводят к суммированию лидирующих асимптотик, как и в перенормируемых теориях.
Об одной задаче многомерной тауберовой теории
Authors: Drozhzhinov Yurii Nikolaevich
Published: September 2020

Во многих тауберовых теоремах асимптотические свойства функций исследовались относительно уже заранее заданной функции (обычно из шкалы правильно меняющихся функций). В работе обсуждается альтернативная задача: пусть дана обобщенная функция; обладает ли она асимптотикой относительно какой-либо правильно меняющейся функции? Найдены необходимые и достаточные условия существования квазиасимптотики таких обобщенных функций, преобразования Лапласа которых имеют ограниченный аргумент в трубчатой области над положительным координатным углом. При этом указана та правильно меняющаяся функция, относительно которой и существует квазиасимптотика. Оказывается, что модуль голоморфной функции в трубчатой области над положительным координатным углом в чисто мнимом подпространстве на лучах, входящих в начало координат, ведет себя как правильно меняющаяся функция. Полученные результаты применяются для отыскания квазиасимптотики обобщенной задачи Коши для уравнений в свертках, ядра которых - пассивные операторы.

Authors: Bykov Dmitrii Vladimirovich
Published: September 2020

Исследуются сигма-модели пространств флагов, допускающие представление нулевой кривизны. Показано, что данные модели можно естественным образом рассматривать как взаимодействующие (голоморфную и антиголоморфную) $\beta \gamma $-системы. Кроме того, при помощи теории нильпотентных орбит комплексных групп Ли устанавливается взаимосвязь сигма-моделей пространств флагов с моделью главного кирального поля.
Гиперболическая спиновая модель Рeйсенарса-Шнайдера на основе пуассоновой редукции
Authors: Arutyunov Gleb Eduardovich , Olivucci Enrico
Published: September 2020

Выводится гамильтонова структура $N$-частичной гиперболической спиновой модели Рeйсенарса-Шнайдера посредством пуассоновой редукции подходящего исходного фазового пространства. Это фазовое пространство реализуется как прямое произведение дубля Гейзенберга факторизуемой группы Ли и другого симплектического многообразия, которое является некоторой деформацией стандартных канонических соотношений для $N\ell $ сопряженных пар динамических переменных. Показано, что модель обладает симметрией Пуассона-Ли спиновой группы $\mathrm {GL}_{\ell }(\mathbb C)$, что объясняет ее суперинтегрируемость. Результаты получены в формализме классической $r$‑матрицы, и они согласуются с последними результатами по другой гамильтоновой структуре модели, установленными в рамках квазигамильтоновой редукции, примененной к квазипуассонову многообразию.

Authors: Haseski Halil İbrahim
Published: September 2020

The present study aimed to determine the effect of individual cyber security skills of pre-service teachers on their attitudes towards computer-assisted education. Thus, the present research was designed as a correlational study. The study participants included 241 senior pre-service teachers in different departments at Manisa Celal Bayar University, Faculty of Education during the 2019-2020 academic year the fall semester. The data were collected with the "Personal Cyber Security Provision Scale" and "The Attitude Toward Computer-Assisted Education Scale." Based on the study findings, pre-service teachers should improve their competency in cyber security. Furthermore, pre-service teachers who owned a personal computer had higher scores in maintaining personal cyber security and had better attitudes towards computer-assisted education. Besides, it was observed that there were differences between personal cyber security scores of pre-service teachers and their attitudes towards computer-assisted education based on their departments. Furthermore, it was identified that the personal cyber security achievement score was a significant predictor of the attitude towards computer-assisted education. In the final section of the study, various recommendations are presented for future studies and applications on the subject.
Guidance for practitioners on the choices of software implementation for frailty models: Simulations and an application in determining the birth interval dynamics
Authors: KARIM MOHAMMAD EHSANUL , KHAN JAHIDUR RAHMAN
Published: September 2020

In clustered survival analysis applications, researchers frequently fit frailty models using parametric and nonparametric approaches to obtain the estimates for the parameters associated with the survival model covariates and heterogeneity (frailty). Availability of the off- the-shelve implementations and freely available R software packages makes it convenient for the practitioners to fit these complicated models easily. Even though there has been a couple of studies assessing the stability of the older packages (e.g., survival, coxme) under a variety of scenarios, some of the newer implementations (e.g., frailtySurv, JM and parfm) have not gone through similar rigorous assessment. It is worth evaluating these new software implementations, and comparing them with the older packages. In the current work, via simulations, we will examine the estimates from all of these popularly used software implementations under a variety of scenarios when the corresponding assumptions related to the baseline hazard and frailty distributions are misspecified. Additionally, true heterogeneity parameter, censoring patterns and number of clusters were varied in the simulations to assess respective impacts on the estimates. From these simulations, we observed that when there is a large number of clusters and mild censoring, Cox PH frailty models fitted using a newer semiparametric estimation technique (from the frailtySurv package) produced regression and heterogeneity parameter estimates that were associated with unusually large bias and variability. On the other hand, when the true heterogeneity parameter is substantially large, the Cox PH frailty models fitted using the coxme package were often producing highly variable estimates of the heterogeneity parameter. The simulation findings then guided our choice of appropriate frailty model in the context of determining the birth interval dynamics in Bangladesh.
A motivação para a proposição de pesquisas por pesquisadores de linguística: uma análise sociorretórica
Authors: Alves Filho Francisco , Lima Carolina Áurea Cunha Rio
Published: September 2020

O objetivo desta pesquisa é analisar a relação que os passos retóricos ‘relatando pesquisa prévia’, ‘indicando lacuna de pesquisa’ e ‘indicando problemas do mundo real’ mantêm com a proposição de projetos de pesquisa escritos por pesquisadores experientes da área de Linguística. A pesquisa insere-se na sociorretórica e se fundamenta em Swales (1990, 2004), Berkenkotter e Huckin (1995), Connor e Mauranen (1995), Motta-Roth e Hendges (2010), Lim (2012, 2014) e Alves Filho (2018). Foram analisados 12 projetos de pesquisa dentro da Linguística. Os passos encontrados foram quantificados e caracterizados em seus aspectos retóricos, como também foi analisada a relação que essas estratégias possuíam entre si e com a proposição da pesquisa. Os resultados indicam que as pesquisas prévias e as lacunas de pesquisa são pouco utilizadas como argumento para uma nova pesquisa e, em contrapartida, a busca pela resolução de problemas do mundo real é assumida como o principal elemento motivador.
Effects of strongly eddying oceans on multidecadal climate variability in the Community Earth System Model
Authors: Jüling André , von der Heydt Anna , Dijkstra Henk A.
Published: September 2020

Abstract. Climate variability on multidecadal time scales appears to be organized in pronounced patterns with clear expressions in sea surface temperature, such as the Atlantic Multidecadal Variability and the Pacific Decadal Oscillation. These patterns are now well studied both in observations and global climate models and are important in the attribution of climate change. Results from CMIP5 models have indicated large biases in these patterns with consequences for ocean heat storage variability and eventually the global mean surface temperature. In this paper, we use two multi-century Community Earth System Model simulations at coarse (1°) and fine (0.1°) ocean model horizontal grid spacing to study the effects of the representation of mesoscale ocean flows on major patterns of multidecadal variability. We find that resolving mesoscale ocean flows both improves the characteristics of the modes of variability with respect to observations and increases the amplitude of the heat content variability in the individual ocean basins. The effect on the global mean surface temperature is relatively minor.
Exploration of students’ thoughts about their right to freedom of education
Authors: Shugurova Olga
Published: September 2020

In this reflective paper, I respond to Dr. Matusov’s (2020) eloquent philosophical exploration of “students’ right to freedom of education. In doing so, I pursue a narrative inquiry (Bruner, 1987; Clandinin, Murphy, Huber, & Orr, 2010; Clandinin, 2013; Hong, Falter, & Fecho, 2017) to explore my students’ self-generated meanings of their educational freedom in our teacher education classroom. I wonder whether freedom of education can be presented as a transcendental concept of self-examination and taught as the student’s right for it without a critical deconstruction of the tentious and fictitious materiality of freedom. Also, I wonder what my students think when they are provoked to claim their right to freedom of education. This reflection reveals that students’ right of freedom is not necessarily about their own self-examination, freedom is a creative force of self-expression. More specifically, freedom is the self-conscious act of discovery of itself (i.e., freedom) in everything my students do as a part of their classroom learning and education. All in all, freedom does not have any meaning at all since meaning emerges in the act of freedom itself, or rather in the creative act of being free.

Published: September 2020

An 8 yr old male castrated hound presented for a left distal ulnar osteosarcoma. Staging (computed tomography and nuclear scintigraphy) did not reveal any metastases. A limb-sparing ulnectomy with local adjunctive carboplatin in a poloxamer copolymer gel (poloxamer 407) was performed. The patient recovered without complications after surgery. No wound healing complications or adverse effects occurred after local use of carboplatin in poloxamer 407. The local recurrence-free interval was 296 days from surgery, and the survival time was 445 days from initial diagnosis. This is the first report in the veterinary literature of using poloxamer 407 as a carrier for local delivery of chemotherapeutic drugs in a clinical patient.

A Paradigm Shift of Learning in Maritime Education amidst COVID-19 Pandemic
Authors: Ochavillo Gregorio Silao
Published: September 2020

AbstractThis paper aimed to determine the maritime students’ readiness to cope with the abrupt paradigm shift from face-to-face to online learning for the first time in maritime education amidst the outbreak of the COVID-19 pandemic. It utilized a descriptive-normative approach where incoming 2nd year and 3rd-year maritime students were the respondents. Data gathering was online using a survey questionnaire in Google Forms. Statistical tools used were frequency count, percentage and a 5% margin of error in projecting students’ population throughout the schoolyear 2020-2021.The study showed a majority or 7 of 10 among maritime students were not ready to cope with the paradigm shift on the basis of not having a computer of their own for school works; no internet connectivity at home; no access to internet shops; and personal wellbeing. Almost 3 of 5 preferred face-to-face learning. Participation was limited with only the maritime students while everybody was under the community lockdowns for safety and health reasons. Internet connectivity of the students also was a limiting factor.A catch-up framework in maritime education for SY 2020-2021, 2021-2022, and 2022-2023 addresses problems relative to the start of SY 2020-2021 by delaying it to January 2021. This will give the maritime students inclusive opportunities to graduate within the prescribed period despite the impact of the COVID-19 pandemic. The government, school authorities, parents and faculty members also benefit from this framework once adapted.
Deconstructing Social Unrest as a Response to Redefine Strained Relationships between Students and University Authorities
Authors: Omodan Dr Bunmi I
Published: September 2020

University system in Nigeria has been characterised by persistent social unrest majorly traceable to strained relationships between students and university authorities. Observations, experiences and literature confirmed that student unrest in the universities had become a compulsory devil affecting the speedy actualisation of university goals and objectives. The need to dismantle the social space for relative peace and tranquillity thereof become expedient. The study aims to redefine students-university authority relationships as a tool to deconstruct social unrest in Nigeria universities. Human Relations Theory of Management (HRTM) was used to theorise the study. Transformative paradigm as a stance to emancipate the existing unrest situation was used to lens the study. Participatory Action Research (PAR) was adopted as a research design for the study. The sample size for this study consists of 10 participants, namely, three students' leaders; one past student leaders, three university management members, two lecturers and two security personnel selected using expert sampling techniques. The Focused Group Discussion (FGD) was used to collect data from the participants, and the data collected were analysed using Socio-thematic Analysis. The study revealed that inadequate funding was a significant challenge resulting in student unrest. In contrast, the provision of Students' Personnel Services coupled with modern maintenance culture, transparency and accountability were found to be the dimension of peaceful university operation devoid of social unrest and therefore becomes a tool to deconstruct the strained relationship between students and university authorities.
Numerical study of ultimate bearing
capacity of rectangular footing
on layered sand
Authors: Panwar V. , Dutta R.K.
Published: September 2020

Purpose: The purpose of this study is to investigate the ultimate bearing capacity of the
rectangular footing resting over layered sand using finite element method.
Design/methodology/approach: Finite element analysis was used to investigate the
dimensionless ultimate bearing capacity of the rectangular footing resting on a limited
thickness of upper dense sand layer overlying limitless thickness of lower loose sand layer.
The friction angle of the upper dense sand layer was varied from 41° to 46° whereas for the
lower loose sand layer it was varied from 31° to 36°.
Findings: The results reveal that the dimensionless ultimate bearing capacity was found
to increase up to an H/W ratio of about 1.75 beyond which the increase was marginal. The
results further reveal that the dimensionless ultimate bearing capacity was the maximum for
the upper dense and lower loose sand friction angles of 46° and 36°, while it was the lowest
for the upper dense and lower loose sands corresponding to the friction angle of 41° and
31°. For H/W = 0.5 and 2, the dimensionless bearing capacity decreases with the increase
in the L/W ratio from 0.5 to 6 beyond which the dimensionless ultimate bearing capacity
remains constant for all combinations of parameters. The results were presented in nondimensional
manner and compared with the previous studies available in literature.
Research limitations/implications: The analysis is performed using a ABAQUS 2017
software. The limitation of this study is that only finite element analysis is performed without
conducting any experiments in the laboratory. Further the study is conducted only for the
vertical loading.
Practical implications: This proposed numerical study can be used to predict the
ultimate bearing capacity of the rectangular footing resting on layered sand.
Originality/value: The present study gives idea about the ultimate bearing capacity of
rectangular footing when placed on layered sand (dense sand over loose sand) as well as the
effect of thickness of top dense sand layer on the ultimate bearing capacity. The findings could
be used to calculate the ultimate bearing capacity of the rectangular footing on layered sand.
Pacific Apostle
Authors: McKay David O.
Published: September 2020

The year-long fact-finding mission of Mormon apostle David O. McKay and his traveling companion Hugh J. Cannon to the colonies of the Church of Jesus Christ of Latter-day Saints was one of the most significant moments of the twentieth century for Mormonism. Although the contemporary church has grown to become a global presence, the early decades of the last century found missionaries struggling to gain converts abroad. For the church’s leadership, it was a pioneering endeavor to visit, observe, and fellowship with the church’s expanding global constituency in the Pacific. Other general authorities had visited individual church missions at various times—especially across Europe. None, however, had ever circumnavigated the globe, using the Pacific as a focal point of travel. In today’s information age, where such visits occur almost weekly for many senior church leaders, the significance of such an expedition is easy to overlook. When McKay was called in October 1920, no one knew the tour would eventually form many of the most important initiatives he had undertaken when he became church president three decades later. McKay’s rich and vivid account of his and Cannon’s 61,646-mile around-the-world journey illustrates the roots of Mormonism’s globalization. His diary account is without doubt one of the more significant texts in the historical cannon of global Mormon studies.
Earl Scruggs and Foggy Mountain Breakdown
Authors: Goldsmith Thomas
Published: September 2020

Earl Eugene Scruggs (1924-2012) came from the hills of North Carolina and learned the banjo from the days he was too small to hold it properly. While still a schoolboy in Boiling Springs, North Carolina, he developed the high-powered three-finger picking method that both him and the banjo famous. At age 21, he joined the founder of bluegrass music, Bill Monroe, on the Grand Ole Opry, completing a sound that Monroe had worked to conceive. Leaving Monroe in 1948, Scruggs and guitarist Lester Flatt started their own group and made recordings including “Foggy Mountain Breakdown.” The lightning-fast banjo instrumental cut a swath through American music, inspiring countless pickers and becoming the “voice” of the business-disrupting 1967 film Bonnie and Clyde. During a long career in music, Scruggs had many famous friends and collaborators. His influence also meant that his Gibson Granada banjo became an icon of American music
“We Simply Illustrate”
Authors: Frisken Amanda
Published: September 2020

This chapter examines sexuality discourse and definitions of obscenity in print media following the Civil War. Editors of illustrated sporting weeklies, such as Frank Leslie (The Days’ Doings) and Richard K. Fox (The National Police Gazette) pushed the boundaries of visual representation. Meanwhile, anti-vice activist Anthony Comstock sought control over what could be seen in print. In pursuing the prosecution of Victoria Woodhull, Tennessee Claflin, Ezra Heywood, and D. M. Bennett, as well as sporting publications, Comstock shifted the focus of visual culture. His success in eliminating images he found shocking distorted the visualization of alleged sexual crimes as primarily the racial assault on white women by men of color. In other words, Comstock helped make the racialized rape/lynching mythos the dominant visual expression of sexual violence.
Prophetic Authority
Authors: MacKay Michael Hubbard
Published: September 2020

This book is about how Joseph Smith established religious authority and a long-lasting, complex priesthood structure. The thesis of this book builds on three scholars’ major ideas about religious authority and Mormonism in the antebellum United States. In an effort to move the conversation toward politics and its relationship to religion, Porterfield focused on the constraint of populism. Though it is true that Mormonism grew, as Hatch shows, from the populist appeal of a lay priesthood and communal living in early Mormonism, Flake demonstrates that the Mormon priesthood was hierarchical. Left just outside the focus of the work of Hatch, Porterfield, and Flake is the role of Joseph Smith defining Mormon authority—a role that has not been fully examined. Smith’s authority grew in opposition to the civic and political authority that evangelicals were garnering and as a countertrend to the populist religious movements of the Second Great Awakening. In fact, Smith’s prophetic voice and scripture formed a hierarchical priesthood structure that eventually empowered every male member of his church to become a prophet, priest, and king, although they answered to each leader above them within the same structure. Reinforced by that structure, Smith’s prophetic voice became the arbiter of authority. It had the ultimate power to create and guide, and it was used to form a strong lay priesthood order in a stable hierarchical democracy devoid of the kind of democratic political authority that evangelicals fostered.
Breath and Reed
Authors: Şenay Banu
Published: September 2020

This is the first of three chapters that sketches out the core perceptual and sensorial transformations that learners go through as they attend to new ways of hearing, listening, and playing. The starting point is the first and ultimately most esteemed action in ney playing: crafting a beautiful sound. To which particular sonic qualities must novices pay attention in their sound-work? What new aural perceptions are at work here? The discussion in this chapter shows that to gain competence in ‘sound-ing well’ also means to enter into the material world of the ‘willful’ reed and to skillfully engage with it.
Musical Islam
Authors: Şenay Banu
Published: September 2020

This chapter redirects discussion to the pressing and more general issue of Muslim ethics, as addressed in the fields of music production and Islamic piety. How does this music-making explicitly relate to Islam? And how does musical apprenticeship train students in a musical Islam? In addressing these questions, the ethnographic exploration reveals how this musical practice facilitates for learners and master musicians a particular way of engaging with Islam, shaping their subjectivities as Muslims, while fostering in them an explorative way of knowing both music and Islam. Theoretically, the analysis contributes to the ongoing conversation in anthropology over Muslim ethics and character formation by engaging with and critiquing the anthropological work on Muslim ‘piety movements’ and ethical ‘self-fashioning.’
You Can’t Eat Scenery
Authors: Strange Jason G.
Published: September 2020

The second of three chapters exploring the history of homesteading in the area around Berea, Kentucky, chapter 3 presents the story of rural subsistence from the late 1800s up to the economic boom generated by World War II. The chapter is framed in terms of the “parable of enclosure”--the idea that yeoman farmers would not voluntarily trade independent livelihood for capitalist wage labor--and argues that as industry and technology generated ever more advanced consumer goods (for example, refrigerators, radios, antibiotics), the peasant way of life became outmoded; once wage labor became available in the factories of the north, millions of Appalachians left the mountains. But, as the chapter documents, some chose to return to a homesteading life, forming an overlooked back-to-the-land movement.
Don’t Need Their Coal
Authors: Strange Jason G.
Published: September 2020

This chapter evaluates contemporary homesteading and rural subsistence in eastern Kentucky as a form of activism and resistance. It argues that homesteading alone is not a particularly effective means of changing larger socioeconomic structures, such as capitalism and plutocracy. However, homesteading, when pursued with skill, is capable of surprising achievements: it can be an effective means of reducing a household’s reliance upon the mainstream economy; shifting work away from wage labor; fostering frugality; bringing homesteaders into closer interaction with the natural world; and serving as a living laboratory for appropriate technologies. These are real accomplishments that explain the continued attraction of this particular form of activism.
Introduction
Authors: Chancy Myriam J. A.
Published: September 2020

The introduction lays out the methodology for the study and explains its key terms. If autochthonomy is the practice of intra-subjective exchanges girded by mobile, local practices, cultural expressions or beliefs that form the intra-diasporic bridge between cultures of African descent, then lakou or yard consciousness is the virtual space in which such exchanges take place. This imagined locus is composed of autochthonous beliefs and practices preserved, reformulated, or syncretized over time, which form the basis for communication because of their importance to the identities of those peoples who have continued to practice them, however modified, to subsist and to persist. This space is one in which filiation and affiliation also become redefined cultural features or markers of association.
Subjectivity in MotionCaribbean Women’s (Dis)Articulations of Being
Authors: Chancy Myriam J. A.
Published: September 2020

In this chapter, Caribbean texts are situated within a crossroads space of intracultural, diasporic exchange to engage a reading practice that uncovers the importance of understanding such texts within the cultural, political, and transnational contexts of their production and dissemination. If, in the past, postcolonial practices focused on displacing, reshaping, or questioning the composition of literary canons, this chapter builds on the previous one to sidestep such questions, or rather to build upon them, by assuming that the utility of the text resides in what it can reveal best about human nature while engaging with the same care and advocacy the epistemes and gnosis of African Diasporic cultures. Texts analyzed include works by Frantz Fanon, Mayotte Capécia, and Mary Seacole.
Conclusion
Authors: Chancy Myriam J. A.
Published: September 2020

The conclusion summarizes the study’s main findings and re-centers the argument that narrow limits of interpretation, when it comes to African Diasporic texts, leads to the persistence of hierarchal models of power relations based on constructions of race, guaranteeing the persistence of racist constructions and consequences upon lived lives. One of the consequences of such misreadings and categorizations also means that the fields of analyses in which these texts circulate replicate interpretive incompetencies. The conclusion summarizes how the study has sought to demonstrate that there are other means of reading African Diasporic texts, such that analyses and critical assessments of such texts are in conversation with and responsive to their interpretive communities.
Business Titan
Authors: Weems Robert E.
Published: September 2020

This chapter examines how Anthony Overton dramatically diversified his financial interests during the 1920s. In 1922, Anthony Overton assumed the presidency of Chicago’s Douglass National Bank (the second black-owned bank to receive a national charter). Two years later, Overton started the Chicago-based Victory Life Insurance Company. In 1927, Victory Life became the only black-owned insurance company granted the right to conduct business in New York State. Following this business coup, Overton, in some circles, became regarded as “the merchant prince of his race.” To further enhance his growing status as a business magnate during the 1920s, Overton built two major commercial structures in the heart of black Chicago’s commercial district (the Overton Building and the Chicago Bee Building).
What Goes Up Must Come Down
Authors: Weems Robert E.
Published: September 2020

In late 1929, Anthony Overton was perceived to be the nation’s most successful black businessman. Yet, by the mid-1930s, the public’s perception of Overton had shifted dramatically. The Great Depression’s negative impact on African American real estate values negatively impacted the profitability of both the Douglass National Bank and the Victory Life Insurance Company. Also, disclosure of Overton’s long-standing, unauthorized funneling of Victory Life funds into Douglass National resulted in his ouster as president of Victory Life. Moreover, despite creative efforts to keep it afloat, the Douglass National Bank ultimately became a casualty of the Depression. In the end, Anthony Overton retained control of the Overton Hygienic Manufacturing Company and the Chicago Bee newspaper but had lost the honorific moniker “the Merchant Prince of his Race.”
The Rural Masquerades of Gender
Authors: Vander Wel Stephanie
Published: September 2020

Chapter 2 focuses on Lulu Belle’s 1930s radio career on WLS’s National Barn Dance as the first female radio star to embody the parodies of southern culture and early country music. Connecting her theatrics and vocal styling to a history of vaudevillian comediennes, this chapter explores Lulu Belle’s early radio performances of unruly hillbilly characters, such as the naive country girl or the man-hungry gal. In her highly publicized marriage to Scotty Wiseman, Lulu Belle’s rustic domestic image was easily conflated with notions of nostalgia, sentimentality, and romance. However, this did not prevent her from slipping in and out of roles to play the part of the demanding, comic wench or the flirtatious mountain gal. Her protean transformations persisted throughout her radio career and into film, helping give shape to historic performative models for women in country music.
Gendering the Musical West
Authors: Vander Wel Stephanie
Published: September 2020

Chapter 3 continues the focus on WLS’s 1930s radio stars and their treatment of gender by examining the musical and cultural significance of Patsy Montana’s singing cowgirl persona. Like Lulu Belle, Montana included a fluid mix of musical styles and vaudevillian practices. But instead of offering parodies of southern culture, Montana’s gender-bending songs took place in the imaginary West. In her musical depictions of tomboy cowgirls and glamorous western heroines, Montana combined virtuosic yodeling with what her listeners described as a “sweet” singing style. As such, she refashioned the West into a place where standard models of gender could include autonomous cowgirls who yodeled to the heights of their vocal range while singing sweetly about the symbolic freedoms associated with frontier individualism.
