LoRaWAN Energy Optimization with Security Consideration
Authors: Khalifeh Ala , Aldahdouh Khaled , Alouneh Sahel
Published: May 2021

Long Range Wide Area Network (LoRaWAN) is an emerging wireless technology that is expected to be widely deployed and implemented in several applications, especially with the promising widespread use of the Internet of Things (IoT) and its potential applications within the Fifth Generation (5G) communication technology. LoRaWAN consists of a number of nodes that monitors and senses the environment to collect specific data, and then sends the collected data to a remote monitoring device for further processing and decision-making. Energy consumption and security assurance are two vital factors needed to be optimized to ensure an efficient and reliable network operation and performance. To achieve that, each of LoRaWAN nodes can be configured by five transmission parameters, which are the spreading factor, carrier frequency, bandwidth, coding rate and transmission power. Choosing the best values of these parameters leads to enhancing the network deployment. In this paper, we shed the light to the security aspect in LoRaWAN network. Then, we introduced an algorithm that depends on the reinforcement learning approach to enable each node in the network to choose the best values of spreading factor and transmission power such that it leads to a lower energy consumption and higher packets’ delivery rate. The results of the simulation experiments of our proposed technique showed a valuable increase in the packet reception rate at the gateway and a significant decrease in the total consumed energy at the end nodes compared with the most related work in literature

Published: May 2021

Contactless biometric systems have increased ever since the corona pandemic outbreak. The two main contactless biometric systems are facial recognition and gait patterns recognition. The authors in the previous work [11] have built hybrid architecture AccessNet. It involves combination of three systems: facial recognition, facial anti-spoofing, and gait recognition. This work involves deploying the hybrid architecture and deploying two individual systems such as facial recognition with facial anti-spoofing and gait recognition individually and comparing the individual results in real-time with the AccessNet hybrid architecture results. This work even involves in identifying the main crucial features from each system that are responsible for predicting a subject. It includes extracting few crucial parameters from gait recognition architecture, facial recognition and facial anti-spoof architectures by visualizing the hidden layers. Each individual method is trained and tested in real-time, which is deployed on both edge device NvidiaJetsonNano, and high-end GPU. A conclusion is also adapted in terms of commercial and research usage for each single method after analysing the real-time test results
Space Traffic Coordination: Developing a Framework for Safety and Security in Satellite Operations
Authors: Blount P. J.
Published: May 2021

This article investigates the extant normative framework that can be identified around the concept of space traffic management (STM). While much of the STM literature engages with how a future regime might be structured, this article attempts to engage with current processes related to space traffic coordination and give insight as to how normative growth toward space traffic management might occur. Through a survey of current legal and governance mechanisms, this article focuses its attention on open data sharing as an extant and critical coordination process that has potential for normative growth in the development of space traffic management as a formal regime.

Sample Size Determination and Optimal Design of Randomized/Non-equivalent Pretest-posttest Control-group Designs
Authors: Bulus Metin
Published: May 2021

A recent systematic review of experimental studies conducted in Turkey between 2010 and 2020 reported that small sample sizes had been a significant drawback (Bulus & Koyuncu, 2021). A small chunk of the studies were randomized pretest-posttest control-group designs, whereas the overwhelming majority were non-equivalent pretest-posttest control-group designs (no randomization). They had an average sample size below 70 for different domains and outcomes. Designing experimental studies with such small sample sizes implies a strong (and perhaps erroneous) assumption about the minimum relevant effect size (MRES) of an intervention; that is, a standardized treatment effect of Cohen’s d < 0.50 is not relevant to education policy or practice. Thus, an introduction to sample size determination for randomized/non-equivalent pretest-posttest control group designs is warranted. This study describes nuts and bolts of sample size determination, derives expressions for optimal design under differential cost per treatment and control units, provides convenient tables to guide sample size decisions for MRES values between 0.20 ≤ Cohen’s d ≤ 0.50.

Dampak Pengembangan Pariwisata terhadap Kehidupan Sosial Budaya dan Ekonomi
Authors: Surwiyanta Ardi
Published: May 2021

Pada visi pariwisata Indonesia tahun 2005, pariwisata nasional dicanangkan menjadi penghasil devisa utama. Namun pembangunan dan pengembangan kepariwisataan membawa konsekuensi yaitu timbulnya dampak sosial budaya. Peranan pariwisata dalam pembangunan negara pada garis besarnya berintikan tiga segi, yaitu segi ekonomis, segi sosial dan segi kebudayaan. Tiga hal yang berpengaruh terhadap kehidupan sosial yang disebabkan dari pariwisata, yaitu: 1. Polarization of The Population, 2. Breakdown of The Family,  3. Development of The Attitudes of a Consumption-Oriented Society; Incident of Phenomena of Social Pathalogy. Pengaruh pariwisata terhadap kebudayaan terjadi karena suatu proses akulturasi antara kebudayaan masyarakat dengan kebudayaan para wisatawan. Dari sisi ekonomi, pariwisata merupakan industri multi komponen, tidak dapat dilepaskan dengan sektor ekonomi lain. Pemasukan tidak hanya dari uang yang dibelanjakan, melainkan juga menarik modal asing. Pariwisata adalah usaha padat karya (labour intensive), menciptakan tenaga kerja di sektor lain. Dalam pengembangan kepariwisataan nasional faktor ekonomis sering menjadi pertimbangan utama dari pengambil keputusan untuk mengembangkan potensi kepariwisataan. Pertimbangan ini kadang lebih ditonjolkan dari pada pertimbangan moral dalam artian kemungkinan pariwisata memiliki dampak sosial yang negatif.

Motor vehicle incidents in postgraduate trainees in British Columbia
Authors: Cassidy Louise , Croft Emma , Erdelyi Shannon , Brubacher Jeffrey
Published: May 2021

Introduction:  Postgraduate medical trainees frequently work ≥ 24- hour shifts causing fatigue and adverse consequences such as motor vehicle incidents (MVIs). We aim to determine the incidence of MVIs during the commutes of trainees in British Columbia (BC) in the preceding year.

Methods: We completed a retrospective, cross-sectional survey of trainees regarding work hours, shifts, and MVIs in the previous year. MVIs included falling asleep while driving, sudden braking or swerving to avoid a collision, unintentionally running a red light or stop sign, or collisions.

Results: Of 273 respondents, over half (54.6%) reported ≥1 MVI, one in 14 were in a collision (7.0%), and two thirds (66.3%) reported that the safety of their commute had been impacted by fatigue in the past year. After adjustment for road exposure and shift-related factors, every ten km increase in commute length was associated with an increased risk of MVI (aOR=1.54;95%CI:1.15-2.12). Reported attentional failures, such as unintentionally running a red light and/or stop sign, increased for every ten hours on-call (aOR=1.44;95%CI:1.03-2.04) and for every additional past-midnight shift worked (aOR=1.13;95%CI:1.01-1.26).

Discussion: Trainees with longer and more frequent commutes had an increased risk of MVIs. Trainees who worked more hours on-call and more past-midnight shifts reported significantly more attentional failures while commuting. This study helps us understand factors affecting trainee commuter safety and supports calls for the provision of safe alternatives to commuting for postgraduate trainees.

Authors: Benouchenne Djamila , Bellil Ines , Akkal Salah , Khelifi Douadi
Published: May 2021

Algerian fir (Abies numidica de Lannoy) is an endemic evergreen tree belonging to the Pinaceae family. Little is known about this plant, and few papers have been reported, despite its traditional uses. The objectives of this study were to investigate the chemical composition of n-butanol extract from A. numidica leaves as well as to evaluate its biological activities (antibacterial and antioxidant). The total phenolics and total flavonoids were found in high amounts (381.15±22.70µg GAE/ml; 49.79±2.81 µg QE /ml, respectively). The data of the antibacterial effect showed a potential inhibitory zone, especially against Proteus vulgaris (17.5±0.70 mm). The antioxidant activity findings disclosed that this fraction has a moderate radical scavenging power and metal chelating ability, compared with the standards used. The liquid chromatography–mass spectrometry (LC–MS/MS) analysis results showed that the major compounds presented in this extract were hyperoside (399.91µg/g), astragalin (147.22 µg/g) and rutin (102.62 µg/g). Thus, A. numidica leaves were suggested as being useful to prevent free radicals and bacterial infections diseases.
The Impact of Sociocultural Changes on Obesity among Arab Women: Kuwait as a Case
Authors: Al-Kandari Yagoub
Published: May 2021

This study aims to reveal the impact of sociocultural changes on obesity among Arab women (Kuwait as a case). A sample of 250 Kuwaiti women, ranging in age from 20 years to 76 years, was selected from all Kuwaiti governorates. The sample was selected from groups with different social, cultural, and economic status in the society. Social and health scales were used. Degree of religiosity, food habits, physical activity scales were used. Height, weight, triceps skinfold, subscapular skinfold, hip circumference, and waist circumference were also used. Whereas the World Health Organization indicates in the February 2018 statistics that 40% of women aged 18 years or older around the world are overweight or obese, the results of the current study show that the majority of the women in the sample are overweight or obese. The results also show that there are differences in obesity rates among age groups. The study found a statistically significant relationship between a women's normal weight and age, education level, socioeconomic status, dietary habits, physical activity, family structure, and family size. The results also indicate that women in Kuwait suffer from the highest rates of obesity and overweight in the world.
Multiple imputation of missing data in multilevel models with the R package mdmb: a flexible sequential modeling approach
Authors: Grund Simon , Lüdtke Oliver , Robitzsch Alexander
Published: May 2021

Multilevel models often include nonlinear effects, such as random slopes or interaction effects. The estimation of these models can be difficult when the underlying variables contain missing data. Although several methods for handling missing data such as multiple imputation (MI) can be used with multilevel data, conventional methods for multilevel MI often do not properly take the nonlinear associations between the variables into account. In the present paper, we propose a sequential modeling approach based on Bayesian estimation techniques that can be used to handle missing data in a variety of multilevel models that involve nonlinear effects. The main idea of this approach is to decompose the joint distribution of the data into several parts that correspond to the outcome and explanatory variables in the intended analysis, thus generating imputations in a manner that is compatible with the substantive analysis model. In three simulation studies, we evaluate the sequential modeling approach and compare it with conventional as well as other substantive-model-compatible approaches to multilevel MI. We implemented the sequential modeling approach in the R package and provide a worked example to illustrate its application.
Statistical modeling of dynamic eye-tracking experiments: Relative importance of visual stimulus elements for gaze behavior in the multi-group case
Authors: Stadler Mara , Doebler Philipp , Mertins Barbara , Delucchi Danhier Renate
Published: May 2021

This paper presents a model that allows group comparisons of gaze behavior while watching dynamic video stimuli. The model is based on the approach of Coutrot and Guyader (2017) and allows linear combinations of feature maps to form a master saliency map. The feature maps in the model are, for example, the dynamically salient contents of a video stimulus or predetermined areas of interest. The model takes into account temporal aspects of the stimuli, which is a crucial difference to other common models. The multi-group extension of the model introduced here allows to obtain relative importance plots, which visualize the effect of a specific feature of a stimulus on the attention and visual behavior for two or more experimental groups. These plots are interpretable summaries of data with high spatial and temporal resolution. This approach differs from many common methods for comparing gaze behavior between natural groups, which usually only include single-dimensional features such as the duration of fixation on a particular part of the stimulus. The method is illustrated by contrasting a sample of a group of persons with particularly high cognitive abilities (high achievement on IQ tests) with a control group on a psycholinguistic task on the conceptualization of motion events. In the example, we find no substantive differences in relative importance, but more exploratory gaze behavior in the highly gifted group. The code, videos, and eye-tracking data we used for this study are available online.

Successful Resection of an Endobronchial Pleomorphic Adenoma Using Cryotherapy: A Case Report
Authors: Mitri Stephanie , Yammine Joseph , Diab Khalil
Published: May 2021

Background: Pleomorphic adenomas are very rare benign bronchial tumors. They are typically either removed surgically, or if not amenable to surgery, via therapeutic bronchoscopy. We present the first case of an endobronchial pleomorphic adenoma removed by cryotherapy.
Case Report: This is the case of a 54-year-old man with a right middle lobe pleomorphic adenoma that was detected incidentally during a bronchoscopy, which was performed due to acute respiratory failure and presence of ground glass opacities on imaging. The tumor led to a chronic cough and partial right middle lobe atelectasis. It was resected successfully using endobronchial cryotherapy without any noted complications. There has been no recurrence of disease one year after the intervention.
Conclusion: This is the first report in the literature of a pleomorphic adenoma successfully removed via cryotherapy without recurrence. Endobronchial cryotherapy appears to be an effective and safe method of removing endobronchial pleomorphic adenomas.
Nonsymmetric Macdonald Superpolynomials
Authors:   University of Virginia, USA, Dunkl Charles F.
Published: May 2021

There are representations of the type-A Hecke algebra on spaces of polynomials in anti-commuting variables. Luque and the author [Sém. Lothar. Combin. 66 (2012), Art. B66b, 68 pages, arXiv:1106.0875] constructed nonsymmetric Macdonald polynomials taking values in arbitrary modules of the Hecke algebra. In this paper the two ideas are combined to define and study nonsymmetric Macdonald polynomials taking values in the aforementioned anti-commuting polynomials, in other words, superpolynomials. The modules, their orthogonal bases and their properties are first derived. In terms of the standard Young tableau approach to representations these modules correspond to hook tableaux. The details of the Dunkl-Luque theory and the particular application are presented. There is an inner product on the polynomials for which the Macdonald polynomials are mutually orthogonal. The squared norms for this product are determined. By using techniques of Baker and Forrester [Ann. Comb. 3 (1999), 159-170, arXiv:q-alg/9707001] symmetric Macdonald polynomials are built up from the nonsymmetric theory. Here ''symmetric'' means in the Hecke algebra sense, not in the classical group sense. There is a concise formula for the squared norm of the minimal symmetric polynomial, and some formulas for anti-symmetric polynomials. For both symmetric and anti-symmetric polynomials there is a factorization when the polynomials are evaluated at special points.

The social outcomes that are attempted to be measured of the Islamic banks in this research paper are derived from social objectives present in literature, in addition to this, Kinder, Lydenberg, Domini Research, 17 Sustainable Development goals of the United Nations, five Environment Social Governance scorecards developed by Oikocredit which is a global cooperative and social investor group, and Analytics index of corporate social performance are used for the derivation of social outcomes.

Findings: Conventional Islamic banks in Pakistan are doing better than Islamic banking units on measures of social responsiveness.

Originality/ Value: This research paper is based on the framework of the research paper “How social is Islamic banking” written on the Islamic banking sector of Indonesia by Luthfi Hamidi and Andrew C. Worthington.

El estudio de la incidencia del desgaste y deformación de los elementos de cierre en las condiciones de operación de la industria es complejo, por lo que es necesario su investigación en las condiciones controladas de los bancos de pruebas. El objetivo del trabajo es realizar un diseño conceptual de un banco de pruebas para la evaluación de la calidad de cierre en latas de conserva circulares que son generalmente utilizadas por empresas dedicadas a la producción de conservas de atún. A partir de un diseño conceptual se estructura una variante de diseño funcional, segura y económica para el banco de pruebas, constituida por una transmisión de potencia por banda en V. Complementariamente se realizó un análisis de resistencia de los elementos de cierre, la selección de rodamiento y análisis de costo. De los resultados del análisis de resistencia, las tensiones máximas en el mandril se distribuyen en el labio que comprime la lata, para las rulinas las deformaciones máximas son de 1,75∙10^(-6) mm en la sección de los perfiles de cierre. El costo de fabricación es 827,87 USD al considerar la adquisición de materiales nuevos. El prototipo permite realizar el proceso de doble cierre de manera correcta y sencilla.

Las enfermedades transmitidas por alimentos son un problema a nivel mundial. Las hortalizas de hoja verde que se consumen principalmente crudas, son uno de los vehículos principales para la transmisión de patógenos humanos. Dentro de ellas se encuentra la lechuga iceberg, que ha aumentado su demanda para consumo debido a los estilos de vida más saludables que se han promovido en los últimos años. El objetivo del estudio fue determinar el nivel de coliformes totales y fecales en lechuga iceberg, obtenidas de manera aleatoria y expedidas en diferentes mercados de la ciudad de H. Caborca, Sonora. El procesamiento, aislamiento e identificación bacteriana se realizó de acuerdo a la NOM-210- SSA1-2014. El 40% de las muestras presentaron coliformes totales y fecales que sobrepasaron los niveles permitidos según la Norma Oficial Mexicana en hortalizas. El estudio reveló un alto nivel de contaminación fecal, esto podría deberse a una mala manipulación de la lechuga iceberg y la necesidad de medidas sanitarias más estrictas para asegurar la inocuidad de este tipo de alimentos.

Bu amaç doğrultusunda, konsültasyon hizmetlerinin ilk belirginleşmeye başladığı 1960-1980 yılları arasında yazılmış 31 makale amaçlı örnekleme yolu ile belirlenerek analiz edilmiştir. Makalelerin seçiminde, Dergi Park, Google Akademik arama motoru ve EBSCOhost-ERIC veri tabanlarından yararlanılmıştır. İncelenen çalışmadan elde edilen veriler, meta sentez araştırma yönteminin içerdiği aşamalar çerçevesinde temalandırılmıştır. İncelenen çalışmalar; amaçlar, örneklem grubu, kullanılan yöntem, veri toplama aracı ve araştırmada elde edilen sonuçlar açısından değerlendirilmiştir. Araştırmalarda kullanılan yöntem çerçevesinde üç tema olarak incelenmesine araştırmacılar tarafından karar verilmiştir. Ardından 20 alt tema elde edilmiştir. İncelenen çalışmaların çoğunlukla tarama yöntemi ve deneysel yöntemle ve en az meta sentez yöntemiyle gerçekleştirildiği görülmüştür. Elde edilen veriler okul konsültasyon hizmetlerinin 1960-1980 yılları arasındaki görünümünü ortaya koyar niteliktedir.
Central Bank Communication: One Size Does Not Fit All

High-quality central bank communication can improve the effectiveness of monetary policy and is an essential element in providing greater central bank transparency. There is, however, no agreement on what high-quality communication looks like. To shed light on this, we investigate 3 important aspects of central bank communication. We focus on how different audiences perceive the readability and degree of reasoning within various economic publications; providing the reasons for decisions is a critical element of transparency. We find that there is little correlation between perceived readability and reasoning in the economic communications we analyse, which highlights that commonly used measures of readability can miss important aspects of communication. We also find that perceptions of communication quality can vary significantly between audiences; one size does not fit all. To dig deeper we use machine learning techniques and develop a model that predicts the way different audiences rate the readability of and reasoning within texts. The model highlights that simpler writing is not necessarily more readable nor more revealing of the author's reasoning. The results also show how readability and reasoning vary within and across documents; good communication requires a variety of styles within a document, each serving a different purpose, and different audiences need different styles. Greater central bank transparency and more effective communication require an emphasis not just on greater readability of a single document, but also on setting out the reasoning behind conclusions in a variety of documents that each meet the needs of different audiences.

A chamada Contrarreforma Agrária de Mercado (CRAM) é uma proposta cunhada no âmbito do Banco Mundial (BM) que concede empréstimos para camponeses comprarem terras de fazendeiros à preço de mercado, isto com vistas a substituir a reforma agrária pela via da desapropriação. Essa proposta começou a ser implantada no Brasil na segunda metade dos anos 1990 por meio do crédito fundiário. Nosso trabalho visa contribuir nesse debate, analisando o processo de territorialização das políticas de CRAM no Pontal do Paranapanema em São Paulo. Observaremos que a expansão da CRAM na região foi um processo articulado pelos fazendeiros e ruralistas como mais uma tática para contrapor o avanço da luta pela terra. Também foi possível ver, pela análise dos empreendimentos do crédito fundiário, em especial o Banco da Terra (BT), a distância entre o discurso do BM e a realidade dos empreendimentos cujos resultados se materializam numa lógica dialética de subordinação e resistência. Como citar este artigo:LIMA, Rodolfo de Souza; PAULA, Ricardo Pires de.
