Photographier le sentiment religieux. Stefan Czarnowski à Perros-Guirec le 26 juillet 1908
Authors: Bert Jean-François
Published: September 2020

Le 26 juillet 1908, Stefan Czarnowski, sociologue polonais proche de Marcel Mauss et d’Henri Hubert, participe à une procession dans la ville de Perros-Guirec. Il décide de la documenter en réalisant dix photographies. Quatre ans avant les deux célèbres clichés de Robert Hertz pris lors du culte de Saint Besse dans les Alpes, les photographies de S. Czarnowski, conservées par Henri Hubert dans son fichier de travail, sont l’un des premiers témoignages de l’intérêt des durkheimiens devant ce type de technique d’enregistrement des données. Cet article s’attache à montrer la manière dont ces derniers ont cherché à « faire voir » ces manifestations de « religion populaire » en insistant tout particulièrement sur leurs conditions matérielles.
« Nous restions les Troubadours de la nature ». D’un lien privilégié à la nature dans quelques familles manouches du Limousin
Authors: Cavaillé Jean-Pierre
Published: September 2020

À partir d’un travail de film documentaire réalisé sur le pèlerinage « gitan » de Saint-Auvent (Haute-Vienne), d’une plus large fréquentation de groupes familiaux du Limousin et de la lecture d’auteurs manouches (Doerr et Stimbach) nous nous interrogeons sur le sens donné dans le discours émique de la communauté manouche limousine à l’affirmation sans cesse réitérée d’une proximité, voire d’une familiarité avec la nature que les Gadjé (non Tsiganes) ne connaîtraient pas. Ce parcours nous conduit de l’analyse des déclarations d’un amour privilégié et réciproque de la nature aperçu comme constitutif de l’identité manouche à l’examen du lien qui unit ce thème de la nature à la mémoire, au respect et en fait au culte discret des défunts.
Cricket (Acheta domesticus) protein hydrolysates’ impact on the physicochemical, structural and sensory properties of tortillas and tortilla chips
Authors: Luna G. Calzada , Martin-Gonzalez F. San , Mauer L.J. , Liceaga A.M.
Published: September 2020

Consumer interest towards consumption of more sustainable protein sources has led way towards the adoption of insect protein for human food applications. Research shows that insect proteins utilised as food ingredients are more promising to be accepted by Westerners. In this study, cricket protein hydrolysates (CPH) were produced using Alcalase (AL) and Flavourzyme (FL) proteases. The physicochemical and structural properties, as well as the sensory acceptability of corn tortillas formulated with 20% (w/w) CPH were evaluated. CPH-tortillas contained all essential amino acids, including 40% of the daily lysine requirement. In raw corn masa (dough), AL-CPH increased the elastic modulus (G’), indicating cross-linking between polymers, while FL-CPH decreased G’. Tortillas formulated with AL-CPH resulted in matrices with low hardness and extensibility values, while FL-CPH tortillas developed a strong and flexible structure, indicating differences in intermolecular interactions between the AL- and FL-CPH and the tortilla matrix in the cooked tortillas compared to the raw masa. Sensory evaluation results showed acceptability (scores>6.0) towards tortillas chips formulated with 20% CPH. Enzymatic hydrolysis of cricket protein can create peptides with functional characteristics and sensory acceptability for their use as ingredients in food formulation.
${\sf {FAST}}$: Disk encryption and beyond
Authors: Chakraborty Debrup , Ghosh Sebati , López Cuauhtemoc Mancillas , Sarkar Palash
Published: September 2020

This work introduces ${\sf {FAST}}$ which is a new family of tweakable enciphering schemes. Several instantiations of ${\sf {FAST}}$ are described. These are targeted towards two goals, the specific task of disk encryption and a more general scheme suitable for a wide variety of practical applications. A major contribution of this work is to present detailed and careful software implementations of all of these instantiations. For disk encryption, the results from the implementations show that ${\sf {FAST}}$ compares very favourably to the IEEE disk encryption standards XCB and EME2 as well as the more recent proposal AEZ. ${\sf {FAST}}$ is built using a fixed input length pseudo-random function and an appropriate hash function. It uses a single-block key, is parallelisable and can be instantiated using only the encryption function of a block cipher. The hash function can be instantiated using either the Horner's rule based usual polynomial hashing or hashing based on the more efficient Bernstein-Rabin-Winograd polynomials. Security of ${\sf {FAST}}$ has been rigorously analysed using the standard provable security approach and concrete security bounds have been derived. Based on our implementation results, we put forward ${\sf {FAST}}$ as a serious candidate for standardisation and deployment.

Published: September 2020

Location information is prerequisite for wireless sensor networks (WSNs) monitoring and control applications, since there is no meaning without position information for collected data. Distance vector hop (DV-Hop) localization algorithm as the typical range-free algorithm that has been widely applied in various applications. Nowadays, the research on range-free localization for WSNs is mostly based on two-dimensional (2D) space. Hence, there are few surveys concentrated on range-free localization in three-dimensional (3D) WSNs. This motivated us to present an extensive overview of enhanced DV-Hop localization algorithms in 3D WSNs. This paper focused on critical challenge between 2D and 3D in localization model, representative range-free 3D localization technique surveys. Moreover, a comprehensive taxonomy of most essential enhanced methods applied in 3D DV-Hop is illustrated. A considerable comparison in term of localization error, computational complexity and node type is given. Future research directions dealing with localization under 3D DV-Hop is also discussed.

Authors: Rida Nouha , Ouadoud Mohammed , Hasbi Abderrahim
Published: September 2020

Road congestion has become one of the major problems of urban cities due to the growth in the number of vehicles and the limitation of road infrastructure. The consequences of this congestion can be seen through a difficult movement of vehicles, an increase in CO2 emissions, increasing energy consumption, and stress for drivers. Intelligent Transport Systems (ITS) based on wireless sensor networks (WSN) have emerged with new solutions and application potentials in the context of the Intelligent city.  In this article, we study an approach of using a wireless sensor network to control the traffic lights of several intersections and optimize their performance by reducing the average waiting time of users. the proposed adaptive traffic light controller determines the traffic lights sequence in real time based on the current traffic situation at the local intersection, the expected arrivals and the degree of congestion at destination intersections. To evaluate our approach, we construct an intersection network of twenty-four intersections with high traffic intensity using the SUMO simulator, the results of the simulation demonstrate the efficiency and practicality of the proposed algorithm.
Blockchain-Enabled Decentralization Service for Automated Parking Systems
Authors: Reddy Keesara Sravanthi
Published: September 2020

Due to recent development in technology and smart devices in people's lives, their lives are becoming easier and safer. One of popular examples in todays is parking (i.e., people find free parking space without moving a long distance or consuming more time or fuel over the road network). Today many automated companies are designing vehicles, but we are still unable to get automatic parking system in an area. Finding free parking slot/space has a probability of revealing user's privacy (i.e., either by service provider to third party/attacker or submitted information [user personal information] can be hacked by an attacker [via performing attacks like Man in Middle, Denial of Service, etc.]). Hence, privacy is a main issue in parking. Providing sufficient privacy in parking to vehicle users is a primary concern of this chapter. For that, this chapter used the blockchain technology to avoid privacy issues (raised in parking searching). Blockchain technology makes reservation of parking slot transparent, decentralized, and secure (privacy-preserved).
Blockchain Risk and Uncertainty in Automated Applications
Authors: Srivastava Devesh Kumar , Bhatt Saksham Birendra , Divyangana
Published: September 2020

Blockchain could be called a string of blocks that acts like a ledger that is also distributed. Members in a defined P2P network are given access to the blockchain and can create new blocks. When the data is stored in a blockchain, changing it becomes virtually impossible. The data stored within blocks is timestamped to avoid tampering. Blockchain has applications in numerous fields like IoT, digital currency, financial services, reputation systems, smart contracts, security services, etc. If any virtual or real asset transaction is happening online, blockchain technology can be easily applied to optimize and secure the transaction better. Blockchain-based applications bring controversies, and yet many exceptional and diverse use-cases have been found for blockchain in both financial and non-financial sectors. Although it holds immense promise, it doesn't come without risks and uncertainties. This chapter elucidates the growing risks and uncertainties which accompany the use of blockchain in automated systems.
Blockchain in Clinical Trials
Authors: Malik Shaveta , Mire Archana , Tyagi Amit Kumar , Boyanapalli Arathi
Published: September 2020

Clinical research comprises participation from patients. Often there are concerns of enrolment from patients. Hence, it has to face various challenges related to personal data, such as data sharing, privacy and reproducibility, etc. Patients and researchers need to track a set plan called study protocol. This protocol spans through various stages such as registration, collection and analysis of data, report generation, and finally, results in publication of findings. The Blockchain technology has emerged as one of the possible solutions to these challenges. It has a potential to address all the problem associated with clinical research. It provides the comfort for building transparent, secure services relying on trusted third party. This technology enables one to share the control of the data, security, and the parameters with a single patient or a group of patients or any other stakeholders of clinical trial. This chapter addresses the use of blockchain in execution of secure and trusted clinical trials.

Authors: Evans Lorraine , Sobel Karen
Published: September 2020

This chapter consolidates aspects of emotional labor that apply to the work of academic faculty and staff. Perspectives will focus on the instructional work librarians do, in the classroom and through research support, and be applied to teaching faculty and support staff in higher education. The collaborative nature of the work, along with the environment and structural components that both enhance and challenge that work, are examined. The chapter describes risk factors that are common and unique to librarianship, such as academic culture, administrative demands, communication, and student support, applying these concepts more broadly in higher education. Pulling from the research on emotional labor, industrial psychology, and the authors' experience in libraries, strategies are presented that can be used or adapted by individuals and departments. Finally, the chapter discusses tensions inherent in the work of those who choose to perform emotional labor: the love of supporting students and faculty through academic and personal challenges versus the exhaustion that sometimes results.

Published: September 2020

Universities are providing higher education and research and are one of the biggest creators of innovation, but very little is understood in terms of digital branding of such innovations that stem from rigorous research activities at universities. Often the university's brand name in terms of its reputation is associated with producing and delivering such innovation but what contributes towards digitally branding that innovation to prospective customers, clients, and marketers for appeal needs to be explored. This chapter presents the main hypotheses effecting Jordanian Digital Learning Management System (JDLMS) model and highlights the benefits and weakness area for each one of them. It also discusses the main factors influencing the acceptance of using DLMS at Jordanian universities, which are IT infrastructure and culture, and the hypotheses between both main factors with perceived usefulness and perceived ease of use to generalise this model in higher educational sectors in Jordanian universities.

Exploring Datafication for Teaching and Learning Development
Authors: Schofield Mark
Published: September 2020

The scale, magnitude, and diversity of higher education teaching/learning and higher education institutions (HEIs) have resulted in corresponding diverse datafication representations. Contrary to conventional datafication, where the objective is profitability (e.g., adopting facial recognition for improved policing), the datafication of HEIs should be analysed, understood, and interpreted for its unique diversity, practice, and consequences. The result of the COVID-19 pandemic has forced a paradigm shift from conventional/traditional classroom-based teaching to online teaching, which has resulted in enhanced data collection. Taking a post-digital perspective on modern practices in higher education literature, this chapter argues for an organic view, in which the datafication must consider the aspects of teaching, learning, and educational context that are absent in digital data. The findings from the discussion lead to the conclusion that datafication can complement expert judgement in HEIs when informed by the unification of pedagogy and technology.

Authors: Hossain M. Kabir , Wood Bob
Published: September 2020

The COVID-19 pandemic has significantly affected all sectors of human endeavour worldwide. This has forced a paradigm shift by disrupting ‘normal' human life, introducing what is now seen as a ‘new normal', which can also be seen as an opportunity rather than a threat. HEIs have equally been affected by this situation, which has forced conventional delivery of teaching and learning to be replaced by distance, online, or blended learning styles. Prior to the pandemic, only slightly over 25% of all students in UK HEIs received teaching and learning online. This statistic has now grown to 85%. This concerns learners' engagement with online learning. Unlike traditional classroom teaching/learning, online learning faces challenges of ensuring the engagement of learners. This chapter aims to explore and discuss measures to enhance student engagement in online learning settings within HEIs. The main objectives are two-fold. First, the study describes what measures exist to enhance student engagement and, second, presents an enhanced framework in online learning in HEIs.

Published: September 2020

Food wastes (FW) has become a crucial global issues. Food production should be increased substantially to meet the need of growing population, high tendency of spoilage and consumer preference are some of the main reasons for food waste. FW predominantly happen in public places such as hotels, hospitals and industrial parks. FW in Sri Lanka, several institutes can be highlighted including schools. 10194 government schools and 80 registered private school chains are functioning throughout the country. In which, total population including both students and teachers are over 4.5 million. Thus, handling large quantity of food in schools, leads to generate huge quantities of FW and it directly affect to the national economy. Therefore, this qualitative research was designed and implemented to determine reasons for FW and evaluate the efficiency of existing FW handling strategies in schools. The data were collected from 12 schools in each educational zone at Kegalle and Kurunegala, through a survey from teachers and students. Majority of students were provided homemade breakfast in both zones, further 20.92% of students in Kegalle and 37.21% of students in Kurunegala have wasted food with some percentage of breakfast daily. In addition, plate waste of free breakfast provided by school was identified as 20.31% of students and 24.62% of students in Kegalle and Kurunegala areas respectively. Free lunch was provided schools only in Kegalle educational zone and among those who was fed from school meal; 37.5% of students have wasted food in various percentages. Majority of students have brought lunch from home and 26.51% of students in Kegalle and 26.12% of students in Kurunegala thrown some amount of lunch daily. FW was comparatively high, when meals provided from school. Further, study revealed that most of school have not established an effective FW handling system within the premises. Therefore, a systematic programs should be implemented to control food wastes. In addition, awareness programs should be carried out to educate students to minimize FW. It is necessary to investigate the reasons for wasting large quantities from school meal. Finally, a national campaign on “Stop Food Waste” should be launched for school community to create a sustainable environmental development with appropriate mechanisms of school and family education.

Published: September 2020

Renal infarction is a rare cause of abdominal pain whose diagnosis is often misunderstood or severely delayed. The difficulty in identifying this time-dependent condition greatly limits the possibilities of therapeutic intervention and determines the loss of renal parenchyma that could have been saved with prompt diagnosis. It is, therefore, essential to include renal infarction in the differential diagnosis in case of abdominal pain and to identify this pathology beforehand. We present a case of a 65-yearold male with atrial fibrillation in therapy with Edoxaban who was admitted to the hospital for acute onset of widespread abdominal pain with nausea, vomit, and a worsening of renal function according to the laboratory tests. An abdominal computed tomography with contrast confirmed the presence of a bilateral renal infarction. The patient developed chronic kidney disease and was discharged on anticoagulant therapy. The aim of this paper is, therefore, to increase physician awareness towards this condition, the best opportunity to diagnose early renal infarction and to establish acute and long-term therapy.
Bacterial infections in cirrhosis: a narrative review and key points for clinical practice
Authors: Mitra Mario , Mancuso Andrea , Politi Flavia , Maringhini Alberto
Published: September 2020

Bacterial infections are frequent complications of liver cirrhosis, accounting for severe clinical courses, and increased mortality. The reduction of the negative clinical impact of infections may be achieved by a combination of prophylactic measures to reduce the occurrence, early identification, and management. Spontaneous bacterial peritonitis (SBP), urinary tract infections, pneumonia, cellulitis, and spontaneous bacteremia are frequent in cirrhosis. The choice of initial empirical antimicrobial therapy should be based on both site, severity, and origin of infection (community-acquired, nosocomial, or healthcare-associated) and on antibiotic resistance patterns. 3rd generation cephalosporins are generally indicated as empirical therapy in most community-acquired cases. However, for nosocomial and healthcare-associated infections, due to a high rate of multidrug-resistant (MDR) pathogens, a broader spectrum treatment is appropriate. In order to prevent antibiotic resistance emergence, microbiological cultures should be collected, and a de-escalation applied when antimicrobial susceptibility tests are available. Standard measures to prevent infections and the identification of carriers of MDR bacteria are essential strategies to prevent infections in cirrhosis. Antibiotic prophylaxis should be applied only to gastrointestinal bleeding, SBP recurrence prevention, and cirrhotics at high risk of a first episode of SBP.

Верификация спектрального анализа "по Ландау и Лифшицу" самосопряженного дифференциального оператора с помощью его функции Грина
Authors: Voronov Boris Leonidovich
Published: September 2020

Подробно разбирается восходящий к Наймарку пример самосопряженного обыкновенного дифференциального оператора, замечательный тем, что точечный и непрерывный спектры оператора пересекаются. Находятся спектр и собственные функции этого оператора "по Ландау и Лифшицу", т.е. в соответствии с правилами, изложенными в их книге "Квантовая механика", основанными на правдоподобных наводящих физических соображениях и аналогиях с линейной алгеброй и, по-видимому, до сих пор не имеющими строгого математического обоснования, а затем приводятся аргументы в пользу разумности полученных этим традиционным для физиков способом результатов, основанные на анализе функции Грина оператора, вычисленной независимо.
Характеризация алгебр мойаловских мультипликаторов для обобщенных пространств типа $S$
Authors: Soloviev Michael Alexandrovich
Published: September 2020

Исследуются свойства алгебр мойаловских мультипликаторов для обобщенных пространств $S^{b_n}_{a_k}$ Гельфанда-Шилова. Доказано, что эти алгебры содержат в себе пространства типа $\mathscr E$ Паламодова. Установлены свойства непрерывности операторов с вейлевскими символами этого класса. Аналогичные результаты получены для проективного варианта пространств типа $S$ и распространены на алгебры мультипликаторов относительно различных трансляционно инвариантных звездочных произведений.
От тождеств Славнова-Тейлора к перенормировке калибровочных теорий
Authors: Zinn-Justin Jean
Published: September 2020

Доказательство перенормируемости и унитарности квантованных неабелевых калибровочных теорий является важной и крайне нетривиальной задачей. Ли и Зинн-Жюстен дали первое доказательство перенормируемости неабелевых калибровочных теорий в спонтанно нарушенной фазе. Их доказательство существенно опиралось на обнаруженную Славновым и Тейлором нелинейную нелокальную симметрию квантованной теории, которая является прямым следствием процедуры квантования Фаддеева-Попова. После введения нефизических фермионов для представления детерминанта Фаддеева-Попова эта симметрия привела к фермионной симметрии Бекки-Руэ-Стора-Тютина квантованного действия и в конечном итоге к результирующему уравнению Зинн-Жюстенa, которое позволяет решать задачи перенормировки и унитарности в наиболее общем виде. Элементарное введение в обсуждение квантовых неабелевых калибровочных теорий поля в духе настоящей работы можно найти, например, в следующих статьях: Faddeev L.D.

Authors: Nepomechie Rafael
Published: September 2020

Известно, что собственные значения трансферматрицы изотропной открытой квантовой цепочки Гейзенберга спина 1/2 с недиагональными граничными магнитными полями удовлетворяют неоднородному $TQ$-уравнению. Получена дискретная вронскианная формула, связывающая решение этого уравнения с соответствующим решением дуального неоднородного $TQ$-уравнения.
Расширение необычных гамильтонианов
Authors: Chanu Claudia Maria , Rastelli Giovanni
Published: September 2020

Понятие расширенных гамильтоновых систем позволяет дать геометрическую интерпретацию некоторых интегрируемых и суперинтегрируемых систем с полиномиальными первыми интегралами, степень которых зависит от рационального параметра. До сих пор процедура расширения применялась только в случае естественных гамильтонианов. Приведено несколько примеров применения этой процедуры к необычным гамильтонианам, таким как гамильтониан системы двух точечных вихрей, гамильтониан модели Лотки-Вольтерра и некоторые гамильтонианы, содержащие четвертую степень импульсов. В ряде случаев получены расширенные гамильтонианы, в других случаях расширение невозможно; кратко обсуждаются причины этого.

В статье рассматривается задача оптимальной остановки диффузионных процессов Ито по некоторому классу моментов остановки. Для случая, когда класс моментов остановки задан параметрически, изучаются необходимые и достаточные условия оптимальности. Подробно исследуется случай одномерных диффузионных процессов и пороговых моментов остановки. Получены необходимые и достаточные условия, при которых пороговый момент остановки будет оптимальным среди всех моментов остановки. Установлен ряд соотношений между решением задачи оптимальной остановки по классу пороговых моментов и решением задачи со свободной границей.
Предельные теоремы для индикаторов рекордов в пороговых $F^{\alpha}$-схемах
Authors: He Patrick , Borovkov Konstantin Aleksandrovich
Published: September 2020

В $F^\alpha$-схеме Невзорова рассматривается последовательность независимых случайных величин, чьи функции распределения суть степени одной общей функции распределения. Ключевое свойство $F^\alpha$-схемы состоит в том, что для нее индикаторы рекордов независимы. Это позволяет получить ряд важных предельных теорем для числа рекордов в такой последовательности до момента времени $n\to\infty$. Мы распространили эти теоремы на гораздо более широкий класс последовательностей случайных величин в "пороговых $F^\alpha$-схемах", когда функции распределения величин близки к степеням общей $F$ лишь в их "правых хвостах", выше некоторых возрастающих неслучайных пороговых значений. Характеризация скорости роста экстремального процесса, которую мы получили для проверки условий нашей главной теоремы, представляет самостоятельный интерес. Мы также установили асимптотическую попарную независимость индикаторов рекордов в специальном случае $F^\alpha$-схем.
Removal efficiency and mechanism of bio-treated coking wastewater by catalytic ozonation using MnO2 modified with anionic precursors
Authors: Zhang Jie , Dong Ben , Ding Ding , He Shilong , Ge Sijie
Published: September 2020

In this paper, MnO2 catalyst were firstly prepared and modified by four kinds of anionic precursors (i.e., NO3-, AC-, SO42- and Cl-) through redox precipitation method. After that, bio-treated coking wastewater (BTCW) was prepared and employed as targeted pollutants to investigate the catalytic ozonation performance of prepared-MnO2 catalyst was investigated and characterized by the removal efficiencies and mechanism of the prepared bio-treated coking wastewater (BTCW), which was employed as the targeted pollutants. Specifically, the effects of specific surface area, crystal structure, valence state of Mn element and lattice oxygen content on catalytic activity of MnO2 materials were characterized by BET, XRD and XPS, respectively. Results showed that COD of BTCW could be removed 47.39% under MnO2-NO3- catalyst with 2 h reaction time, which was much higher than that of MnO2-AC- (3.94%), MnO2-SO42- (12.42%), MnO2-Cl- (12.94%) and pure O3 without catalyst (21.51%), respectively. So, MnO2-NO3- presented the highest catalytic performance among these catalysts. The reason may be attributed to a series of better physiochemical properties including the smaller average grain, the larger specific surface area and active groups, more crystal defect and oxygen vacancy, higher relative content of Mn3+ and adsorbed oxygen (Oads) than that of another three catalysts.
