A comparison of adoption and service quality between large and small broadband internet service providers in Thailand
Authors: Namahoot Kanokkarn Snae , Jantasri Viphasiri
Published: May 2021

This research aims to compare the influence of service quality on intention to use broadband internet through attitudes and technology acceptance, as mediator variables between large and small broadband internet service providers (ISPs) in Thailand. A comprehensive review of the literature has modified the development of this behavioral model that explains intention to use of broadband internet. A data set from two groups: large and small broadband ISPs, nationwide survey was conducted in Thailand (n = 928 consumers). The theoretical model was tested using structural equation modeling. The findings show that integrated models have good explanatory power (78.3 percent) to predict customer’s intention to use broadband internet. The results of this study are as follows. Firstly, service quality: tangible, reliability, responsiveness, assurance and empathy, supports second-order factor analysis. Service quality has an influence on attitude, perceived usefulness, perceived ease of use, and intention to use broadband internet both two types of service providers. Secondly, perceived usefulness has a significant effect on attitude, and intention to use only in small companies. Thirdly, attitude, perceived usefulness, and perceived ease of use as mediator variables have a positive effect between service quality and intention to use broadband internet. This study proposes customer acceptance on broadband internet using a modified TAM.to reveal the impact of service quality on intention to use. The results of this study can be replicated and extended to ASEAN countries. The conclusions and implications for management provide alternatives for companies to increase the number of internet users in order to improve overall quality of life.
The effects of teaching and learning political economy in Vietnamese educational system
Authors: Tran Hien Van
Published: May 2021

This study aims to understand and test the factors influencing the effectiveness of learning and teaching political economy among Vietnamese universities. Over 1500 students from different majors and different school years have taken part in this study. The data collected from questionnaires was analyzed by SPSS version 2016 and EVIEW 10. From this study, it can be said that learning motivations and teaching methods are the most important factors driving the success of teaching and learning the political economy. Furthermore, males seem to be more interested in studying this subject and getting a higher GPA compared to females. Students from higher school-year, by contrast, have lower levels of interest in studying this module, leading to the lower effectiveness in teaching and learning this module. Finally, while teaching methods and teaching quality are positively correlated with the dependent variable, the administration service and infrastructure negatively influence the teaching and learning objectives.

Authors: Nor Jannah Hassan  , Safani Bari  , Norshidah Mohamad Salleh  , Mohamad Iskandar Shah Sitam
Published: May 2021

The importance of Islamic faith, which forms the foundation of good manners, is less emphasized in our schools’ curricula at the present. As a result, social illness among adolescents becomes a serious concern. Currently, some Islamic teachings on manners are embedded in a subject called Islamic Religious Education. The Islamic teaching usually emphasizes on the well-being of mankind. This study highlights the needs of Islamic teaching on manners through Mathematics courses. The goals are to (i) promote noble characters among students with visual impairments, (ii) produce quality students to become capable of understanding and doing the Mathematical ideas, and (iii) gain knowledge and apply the Mathematics skills in their daily lives. In Malaysian context, students with visual impairment get access to knowledge depending entirely on the help of their teachers. Therefore, inculcating the Islamic manners to students with visual impairment often requires extra time not only during religious teaching but also in other subjects, especially in Mathematics. Mathematics plays an important role in education. It continues in the 21st-century and beyond. It is also considered as a basic domain for economic and social development in Malaysia. Furthermore, Mathematics based knowledge is treated as a goal in Malaysian Education Development Plan for 2013-2025. Indeed, Mathematics has a minimal bias and the subject has a strong sense in ethical orientation. Therefore, inculcating Islamic manners through Mathematics courses should be addressed. In this study, the qualitative approach was applied.

El Mal Querer como álbum visual: simbología de lo español, apropiación y narrativa transmedia en los videoclips de Rosalía
Authors: Sedeño-Valdellos Ana María
Published: May 2021

La narrativa transmedia supone una nueva configuración de los proyectos culturales mediados a través de los canales de comunicación, que combina los tradicionales (televisión, radio, medios impresos) con los novedosos (medios online, redes sociales). En ellos se trasciende la gestión única de los mensajes, se planifica de forma que adquieran sentido a través de los medios y se diversifican los momentos de liberación de estos mensajes. El álbum visual, como heredero del álbum conceptual de rock, establece un formato extendido en la idea de videoclip musical, donde la unidad y la coherencia de los discursos visuales son rasgos primordiales. El artículo examina los motivos visuales a modo de símbolos reconocibles de la tradición española y la apropiación cultural que hace de ellos el álbum visual El Mal Querer de Rosalía (2018). El análisis se enmarca en una reflexión sobre el videoclip actual y otros conocidos álbumes visuales.
Geology and Concepts of Genesis of Important Types of Uranium Deposits
Authors: Nash J. T. , Granger H. C. , Adams S. S.
Published: May 2021

Uranium ore deposits occur in nearly every major rock type in the earth’s crust, and nearly all igneous, metamorphic, and sedimentary processes are capable of concentrating or dispersing uranium. However, only three types of deposits account for more than 70 percent of known Western World Reasonably Assured Resources (WWRAR): Precambrian quartz-pebble conglomerate type, Proterozoic unconformity type, and Phanerozoic sandstone type. Igneous-related processes in plutonic, volcanic, and magmatic-hydrothermal environments, considered important 25 years ago, now account for less than 10 percent of world resources known at present.

The oldest known ore deposits were formed in conglomerates by placer processes under unique anoxic conditions. For the last 2.2 b.y., since oxygenation of the atmosphere, the genesis of both high- and low-temperature deposits has been dominated by three general geochemical processes: (1) oxidation of uranium to soluble U(VI) species permitting aqueous transport, perhaps most commonly as uranyl-carbonate complexes; (2) reduction, principally by C, S−2, or Fe+2 species, to U(IV) to allow precipitation of uraninite (pitchblende), and coffinite, although the specific reductant commonly cannot be determined because these three tend to be associated geologically; and (3) igneous and metamorphic differentiation caused by exclusion of uranium from crystal structure of most rock-forming minerals.

The geochemistry of uranium ore-forming processes has changed in time because of the evolution of life forms and their impact on the earth’s oxygen and carbon budgets. This evolution is reflected in changing predominance of ore types in geologic time: (1) pre-2.8 b.y. ago—no known uranium ore deposits; (2) ca. 2.8 to 2.2 b.y. ago—the first intràcratonic basins and anoxic atmosphere permitted accumulation of placer deposits of uraninite in quartz-pebble conglomerates; these deposits contain about 19 percent of the western world’s resources; (3) ca. 2.2 to 0.4 b.y. ago—following oxygenation of the atmosphere uranium was oxidized and transported as soluble U(VI) complexes to sites of reduction, commonly in organic carbon-rich marginal marine environments. Diagenesis, metamorphism, and near-surface redox enrichment subsequently formed unconformity-type, ultrametamorphic-type, and vein-type ore deposits which together contain more than 25 percent of the western world’s resources; (4) ca. 0.4 b.y. ago to present—after development of land plants the most important ore-forming process was redox-controlled deposition from ground water in continental sediments. Sandstone-type deposits, characteristic of this stage, contain about 40 percent of the western world’s resources.
Gamma-Ray Spectrometry in Geologic Mapping and Uranium Exploration
Authors: Ward Stanley H.
Published: May 2021

Gamma-ray spectrometry, airborne or ground, may be useful in a wide variety of geologic mapping applications because the concentrations of uranium, thorium, and/or potassium may be diagnostic of rock type in many uranium, base, and precious metal environments. However, in areas of little outcrop, the surface material must be either residual or locally derived before gamma-ray spectrometry can be applied successfully. In its alternate application—direct detection of uranium—gamma-ray spectrometry has been remarkably successful in recent years. However, for direct detection of uranium deposits, gamma-ray spectrometry will decrease in its application because most deposits occurring sufficiently close to surface to be detected have already been found.

To be of maximum use to the explorationist, data from gamma-ray spectrometry surveys must be acquired with utmost care. Accordingly, attention must be directed to the evaluation of such problems as disequilibrium in the uranium decay series, removal of atmospheric background radiation, the effect of rainfall and other meteorological phenomena, calibration of spectrometers, statistical errors in count rates, fields of view of gamma-ray detectors, and the effect of overburden. Modern instrumentation, calibration, and analysis are such that data can be evaluated with such care that as little as 1 ppm U, 1 ppm Th, or 0.1 percent K can be detected reliably with an airborne or ground gamma-ray spectrometry survey.

From Dialogic Tension to Social Address: Reconsidering Mandolfo's Proposed Didactic Voice in Lament Psalms
Authors: Suderman W. Derek
Published: May 2021

In God in the Dock, Carleen Mandolfo argues that the move from second person speech to God to third person description of the divine within “dialogic psalms” reflects the “interjection” of a secondary voice. While her focus on speech to a human audience is significant, the criteria she employs prove problematic. Rather than multiple voices, the psalms Mandolfo discusses are better understood as reflecting shifts in address between multiple audiences spoken by a single supplicant.
ON GENERAL EULERIAN INTEGRAL FORMULAS AND FRACTIONAL INTEGRATION
Authors: GUPTA K. C. , GOYAL S. P. , LADDHA R. K.
Published: May 2021

In the present work, we evaluate a unified Eulerian type integral whose integrand involves the product of a polynomial system and the multivariable H-function having general arguments. Our integral formula encompasses a very large number of integrals and provides interesting unifieation and extensions of several known (e.g., [1], [3], [4], [5], [9], [11], etc.) and new results. Since the integral has been given in a compact form free from infinite series, it is likely to prove useful in applications. Three special cases of the main integral (which are also sufficiently general in nature and are of interest in themselves) have also been given. Finally, the main integral formula has been expressed as a fractional integral operator to make it more useful in applications.

Inter-Relationships Among Several Person-Related Attributes in Reading and Metacomprehension: Complexity and Educational Implications
Authors: Agler Lin-Miao L. , Alfsen Larisa K
Published: May 2021

Reading is one of the most basic academic skills. An accurate monitor of one’s text comprehension (i.e., metacomprehension) is essential for effective reading as it guides learning and choices of appropriate strategy used to maximize overall understanding. The processes of reading comprehension and metacomprehension are affected by text-related, task-related, and reader- /person-related factors. One of the two purposes of this report is to provide a brief review of consistent research findings on the interrelationships among several person-related variables and the complexity of those associations in reading and metacomprehension. The person variables discussed include personality, motivation, goal orientations, self-regulation, reading strategy use, and academic effort expenditure. A second purpose is to highlight practical educational implications from the prominent research evidence for classroom teaching.
Implementing Inclusive Education In Early Childhood Settings: The Interplay and Impact of Exclusion, Teacher Qualities and Professional Development in Ghana
Authors: Ackah-Jnr Francis R. , Udah Hyacinth
Published: May 2021

Inclusive education (IE) in the early years enhances young children’s learning, socialization, and development; yet, children with disability are one group that is often isolated, excluded, or marginalized in early childhood education. This paper examines jointly the perceived exclusion practices, teacher qualities, and professional development and the interplay and impact of these factors on effective inclusive early childhood education. Drawing on data collected from individual interviews with teachers and headteachers in a large early childhood and school setting in Ghana, findings of this qualitative study indicate the exclusion practices of teachers. The findings suggest that resistance to IE limits learning, engagement, and social opportunities for children, especially those with disability. The findings also identify that effective teacher qualities and professional development enhance the provision of quality inclusive early childhood education. The study reinforces the need for improved support for teachers and to make sure that they are placed at the center of IE policy and practice.

Anatomy of Cerebellum
Authors: Sajja Srinivasa Siva Naga Rajasekhar
Published: May 2021

The cerebellum receives inputs from spinal cord, cerebrum, brainstem, and sensory systems of the body and controls the motor system of the body. The Cerebellum harmonizes the voluntary motor activities such as maintenance of posture and equilibrium, and coordination of voluntary muscular activity including learning of the motor behaviours. Cerebellum occupies posterior cranial fossa, and it is relatively a small part of the brain. It weighs about one tenth of the total brain. Cerebellar lesions do not cause motor or cognitive impairment. However, they cause slowing of movements, tremors, lack of equilibrium/balance. Complex motor action becomes shaky and faltering.

Published: May 2021

This chapter examines and explores the potential of how the capabilities of the emerging 5G cellular technologies can be integrated with a given mission-critical xIoT application (e., g., smart grid) to enable a truly converged xIoT-ICT infrastructure that would further enhance and enable the adequate support of the strict performance requirement of such an xIoT application. Since the smart grid believed to be one of the most necessitated IoT services. in this work, it has been nominated as a descriptive xIoT case. As the smart grid comprises an extensive collection of applications extended from mission-critical services which have rigorous necessities in terms of end-to-end (E2E) latency and reliability (e.g., real-time system protection and control utilizing PMU measurements) to those that require support of massive number of connected machine-to-machine (M2M) devices with relaxed latency and reliability requirements (e.g., smart meters). Based on time-to-market strategy, we identify and propose two different 5G-based business and architectural models that enable a truly converged power grid-ICT infrastructure, namely, near-term model and long-term model.
Organization and implementation of online language and literature courses at faculties and secondary schools in Serbia
Authors: Škobo Milena
Published: May 2021

The aim of this paper is to determine the ways in which the online language and literature courses had been conducted in secondary schools (and high schools) and faculties across Serbia, when the pandemics caused by the appearance of coronavirus forced all educational institutions worldwide to abandon the traditional way of teaching and adopt the new teaching practices which took place in virtual environments. One of the key issues explored in this paper is whether the language and literature teachers in Serbia had been provided with enough teacher training regarding the use of online platforms and online tools, as well as whether they had had previous experience in an online course design, its organisation and realization. The paper examines the following hypotheses: it is assumed that the concept of distance learning in Serbia has not come to fruition (1) and that the lack of digital literacy of both teachers and students is the result of the country's poor development of e-Learning, as well as the lack of suitable teacher training systems that would provide teachers with practical knowledge in regard with dealing with online platforms and proper use and application of the most innovative digital tools (2). The obtained results have confirmed the hypotheses set up in the paper. The results point to the need for conducting further research into this field, in particular, when it comes to proper organization of online language courses as well as the redifiniton of the goals and methodologies established in online language courses. Moreover, the results stress an urgent need for designing and implementation of an entirely new concept in Serbia - an online literature course model - that has not been explored yet and that calls for an immediate research into the field of literature and the methodology of teaching literature.

En el presente estudio pretendimos analizar las características de los autores de agresiones sexuales cuyo modus operandi es el de atacar a la víctima en portales o entradas de garaje de edificios. Nuestro estudio estuvo orientado a determinar si es posible predecir tales características a partir de los datos de la escena del crimen, analizando casos resueltos. Partiendo del contenido de sentencias judiciales condenatorias dictadas en España, y aplicando pruebas estadísticas de chi-cuadrado, odds-ratio, y regresión logística binaria, hemos obtenido resultados alentadores, en el sentido de que algunas de las variables de la escena del crimen permiten predecir algunas características de los autores. Dado que las variables de la escena del crimen utilizadas aquí son conocidas por el equipo policial al inicio de la investigación, la predicción de características del agresor sexual podría ser de utilidad a la hora de priorizar sospechosos.This paper aims at analysing the features of the perpetrators of sexual assaults whose modus operandi consists of assaulting the victim in doorways or entrances of garage and buildings. Its objective was to determine whether it is possible to predict these features moving from the information regarding the crime scene, by means of analysing solved cases. Moving from the content of convicting judgments issued in Spain, and by applying statistical tests of chi-square, odds-ratio, and binary logistic regression, we have obtained encouraging results, in that some variables in the crime scene allow to predict some features of these offenders. Since the variables of the crime scene that have been used here are known to the police team at the beginning of the investigation, prediction of the sexual offender’s features could be useful to prioritize suspects.
Entrer en Monologues intérieurs avec le monde
Authors: Bélanger Jennifer
Published: May 2021

La crise sanitaire liée à la COVID-19, et le confinement qui en découle, a sommé les artistes de la scène de se réinventer, de faire preuve de créativité et de résilience, avec ce que ces mots induisent de pression pour contourner les impacts majeurs agissant sur le quotidien de leur pratique. Il·elles devaient faire volte-face, souvent sans le soutien nécessaire et dans l’urgence de saisir ce présent trouble. En passant par une réflexion sur ce qui persiste de vivant dans les arts lorsque les corps en présence sont cachés derrière leur écran, ce parcours critique retrace mon expérience de spectatrice des Monologues intérieurs, une initiative créée par Éric Noël en plein coeur de la crise et appuyée par le Centre des auteurs dramatiques du Québec (CEAD). Je propose une traversée sensible qui résonne avec le dehors et qui questionne l’irruption du réel dans les performances, les limites et les possibles de la réception altérée par la distance, les privilèges qui nous permettaient d’assister aux directs deux soirs par semaine. Ces lectures, où les textes déclamés étaient réinterprétés sous le prisme de la vie actuelle, nous conviaient à d’« autres modes d’attention » (Despret, 2019) et à d’autres manières de partager l’ici et le maintenant propres aux arts vivants.

Beta-amyloid (Aβ) and tau proteins, the pathological hallmarks of Alzheimer’s disease (AD), are believed to spread through connected regions of the brain. Combining diffusion imaging and positron emission tomography, we investigated associations between white matter microstructure specifically in bundles connecting regions where Aβ or tau accumulates and pathology. We focused on free-water-corrected diffusion measures in the anterior cingulum, posterior cingulum, and uncinate fasciculus in cognitively normal older adults at risk of sporadic AD and presymptomatic mutation carriers of autosomal dominant AD. In Aβ-positive or tau-positive groups, lower tissue fractional anisotropy and higher mean diffusivity related to greater Aβ and tau burden in both cohorts. Associations were found in the posterior cingulum and uncinate fasciculus in preclinical sporadic AD, and in the anterior and posterior cingulum in presymptomatic mutation carriers. These results suggest that microstructural alterations accompany pathological accumulation as early as the preclinical stage of both sporadic and autosomal dominant AD.
The effect of host community functional traits on plant disease risk varies along an elevational gradient

Quantifying the relative impact of environmental conditions and host community structure on disease is one of the greatest challenges of the 21st century, as both climate and biodiversity are changing at unprecedented rates. Both increasing temperature and shifting host communities toward more fast-paced life-history strategies are predicted to increase disease, yet their independent and interactive effects on disease in natural communities remain unknown. Here, we address this challenge by surveying foliar disease symptoms in 220, 0.5 m-diameter herbaceous plant communities along a 1100-m elevational gradient. We find that increasing temperature associated with lower elevation can increase disease by (1) relaxing constraints on parasite growth and reproduction, (2) determining which host species are present in a given location, and (3) strengthening the positive effect of host community pace-of-life on disease. These results provide the first field evidence, under natural conditions, that environmental gradients can alter how host community structure affects disease.
Collective view: mapping Sargassum distribution along beaches
Authors: Arellano-Verdejo Javier , Lazcano-Hernández Hugo E.
Published: May 2021

The atypical arrival of pelagic Sargassum to the Mexican Caribbean beaches has caused considerable economic and ecological damage. Furthermore, it has raised new challenges for monitoring the coastlines. Historically, satellite remote-sensing has been used for Sargassum monitoring in the ocean; nonetheless, limitations in the temporal and spatial resolution of available satellite platforms do not allow for near real-time monitoring of this macro-algae on beaches. This study proposes an innovative approach for monitoring Sargassum on beaches using Crowdsourcing for imagery collection, deep learning for automatic classification, and geographic information systems for visualizing the results. We have coined this collaborative process “Collective View”. It offers a geotagged dataset of images illustrating the presence or absence of Sargassum on beaches located along the northern and eastern regions in the Yucatan Peninsula, in Mexico. This new dataset is the largest of its kind in surrounding areas. As part of the design process for Collective View, three convolutional neural networks (LeNet-5, AlexNet and VGG16) were modified and retrained to classify images, according to the presence or absence of Sargassum. Findings from this study revealed that AlexNet demonstrated the best performance, achieving a maximum recall of 94%. These results are good considering that the training was carried out using a relatively small set of unbalanced images. Finally, this study provides a first approach to mapping the Sargassum distribution along the beaches using the classified geotagged images and offers novel insight into how we can accurately map the arrival of algal blooms along the coastline.

Introduction: Brucellosis is a highly infectious zoonosis affecting humans and animals. It is a multi-burden disease leading to severe economic losses due to disability in humans, and it also causes abortion, infertility, and reduced milk production in animals. An essential element for effective prevention and control of brucellosis is to improve Knowledge, Attitude and Practice (KAP) of the community. Aim: To evaluate KAP for human brucellosis to determine the risk factors among Migratory Animal Handlers (MAH) in Nagpur and Chandrapur district of Maharashtra state in India. Materials and Methods: A cross-sectional study was conducted on 143 subjects chosen randomly from Nagpur and Chandrapur districts, Maharashtra. A structured and validated questionnaire was used for demographic characteristics and KAP. Data was entered in Microsoft Excel and analysed by SPSS. Descriptive statistics accustomed to demographic feature and KAP. Results: All 143 respondents (87 from Nagpur and 56 from Chandrapur) were males. Age ranged from 20 to 50 years. The majority of 139 (97%) respondents were married. Of 143 respondents, none had heard of brucellosis, 125 (87%) consumed unpasteurised milk, 37 (26%) assisted during calving, and 34 (24%) milking the animal. None of the respondents used protective clothing while assisting in animal delivery or handling birth products. One hundred and thirty six (95%) respondents informed that they treated the animal without consulting a veterinarian. Conclusion: This study showed poor knowledge and high-risk behaviours and self-reported practices for brucellosis among MAH. Public health education for MAH should be enhanced with full capacity as an integral part of the National Control Program on Brucellosis in India.

In today’s keen competitive global environment, schools and institutions of higher learning are entrusted to produce quality human capital that is able to participate and cope with the ever changing market demands in various sectors of the economy such as education, business and commerce, and technology. The quality of education that students receive is inextricably linked to the knowledge, intelligence, professional skills and competencies of teachers. Teachers are the major in – school influence on student achievement and the most influential profession in the society that make huge differences to children’s lives. The professional roles and qualities of the teacher are blended to make him/her an effective teacher. With teacher preparation issues becoming a major concern for many societies today, it is therefore crucial to shed more light on pre-service teachers teaching practice program aimed at positively influencing the quality level of our student teacher preparation to assist them in carrying out their core mandate as and when they become fully grown teachers. The issues in focus are; the concept of teaching practice, why the need for teaching practice for student teachers, supervisors and supervision, supervisions and feedback, and challenges in supervision.
