Published: July 2020

AbstractWi-Fi-based indoor positioning for determining accurate wireless indoor location information has become crucial in meeting increasing demands for location-based services by leveraging the Internet of Things (IoT) and ubiquitous connectivity. Most Wi-Fi-based indoor positioning techniques using wireless received signal strength (RSS)-based methods are affected by the indoor environment and depend on the respective signals from at least three reference access points. In this paper, we propose a cloudlet-based cloud computing system enabling Wi-Fi indoor positioning and navigation through a Wi-Fi located on a one-hop wireless network. Our cloudlet-based cloud computing system provides the reference point data and real-time interactive response for a self-driving indoor cart. The system was tested in a real environment with the following results: (1) our system autonomously performed actions, such as turning right or left or going straight according to a movement decision algorithm and determined the position within a stable range of Wi-Fi coverage; (2) the cloudlet and core cloud can track navigation for an indoor self-driving cart; (3) the global and local positions designed for reference access points and a specific position can navigate the self-driving cart to a particular position accurately; (4) the moving edge clouds play a role in deciding three action movements (go straight, turn left, and turn right), as well as managing the local position of the items; and (5) a core cloud is deployed to store all information for the items, such as their positions and corresponding Wi-Fi locations. A core cloud manages items that have the same position (i.e., a global position) defined as the corresponding Wi-Fi location. Finally, the practical results have significance in designing a cloudlet-based cloud computing system enabling Wi-Fi indoor positioning and navigation.

Abstract
Background
Healthcare-associated infections (HAIs) are a global public health problem. For the fulfillment of Saudi Arabia’s Vision 2030, the promotion of preventive care medicine through HAI management is a crucial issue. This study explores the perspectives of Saudi tertiary healthcare workers (HCWs) on HAIs and infection control measures.

Methods
Quantitative data were assessed to determine HCWs’ knowledge of HAI and their attitudes towards and practice of infection control measures. Semi-structured interviews were used to collect qualitative data from 40 doctors and nurses. The interviews were audio-recorded and transcribed verbatim. Further, routine sterile procedures in the wards and intensive care units were video recorded, and the footage was discussed by the infection control team and the personnel involved in the videos. This discussion was videographed and transcribed. Both interview data and reflective discussion of the video were analysed using thematic analysis. The quantitative data were analysed using the Kruskal–Wallis test and logistic regression analysis.

Results
Kruskal–Wallis test revealed no difference in mean knowledge, attitude, or practice scores between nurses/ doctors or the genders. There was a significant difference in knowledge score and practice scores between the Intensive care unit & the Paediatric ward /infection control department with the maximum scores in knowledge and practice among participants from the intensive care unit. Logistic regression analysis for dependent variables (knowledge and attitude) and independent variables like age, gender, designation, and departments was not significant. The qualitative data yielded four themes: knowledge of HAI and infection control, infection control measures in practice, a shortfall in infection control measures and HAI, and required implementation. Video-reflexive ethnography (VRE) revealed lapses in handwashing practice and proper usage of personal protective equipment (PPE), especially surgical masks.

Conclusion
Early introduction of training programmes in medical and nursing schools and video demonstrations of appropriate infection control practices during sterile procedures would be highly beneficial to HCWs. A possible reason for the outbreak of Middle East Respiratory Syndrome coronavirus in this part of Saudi Arabia could be a lapse in PPE usage. Intensive training programs for all the HCWs, strict vigilant protocols, and a willingness to change behaviour and practice, will significantly benefit the spread of outbreaks.

Abstract
Background
To document 18F-Fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) findings after percutaneous cryoablation for early breast cancer.

Methods
Data of 193 consecutive patients who had undergone cryoablation for invasive ductal carcinoma or ductal carcinoma in situ ≤ 15 mm without a history of ipsilateral breast cancer, synchronous ipsilateral lesion, and with estrogen receptor positive/human epidermal growth factor 2 negative were enrolled. The imaging characteristics of the treated areas were evaluated and classified on CT images as one of two types: fatty mass or non-fatty mass type. The maximum standardized uptake value (SUVmax) of the initial post-cryoablation PET/CT, the CT type of the treated area and selected clinical factors (age, menopausal status, lesion area, breast density, timing of PET/CT) were retrospectively evaluated.

Results
The median interval between cryoablation and the initial post-cryoablation PET/CT was 12 months. The median SUVmax of the treated area was 1.36. The CT findings of the treated area were classified as fatty mass type (n = 137, 71.0%) or non-fatty mass type (n = 56, 29.0%). The treated areas of patients with lower breast density, of older age, post-menopausal status, and lower radiation dose were significantly more likely to be of fatty mass type (P < 0.001). Non-fatty mass type averaged a significantly higher SUVmax than did fatty mass type.

Conclusions
Post-cryoablation PET/CT findings are of fatty or non-fatty mass type. A non-fatty appearance, which can show higher SUVmax, does not necessarily denote recurrence.

Published: July 2020

AbstractBackgroundCerebral ischemia initiates an oxidative stress response in the brain which is a composite process that involves many oxidative stress biomarkers. High levels of malondialdehyde (MDA) in patients with acute ischemic stroke had been found. The evaluation of oxidative stress in the acute stage may contribute to improve the post ischemic stroke outcome.ObjectiveThe aim of the current study to assess MDA level, as an oxidative stress biomarker, in acute ischemic stroke on admission and its relation with stroke severity on admission and also, its relation with three months short-term outcome.MethodsForty-two patients (20 males and 22 females) with acute ischemic stroke were prospectively enrolled in follow-up cohort study. Serum MDA was measured within 24 h after admission. We studied the relationship between MDA and stroke severity and functional outcome after 3 months assessed by National Institute of Health Stroke Scale (NIHSS) and modified Rankin Scale (mRS) respectively.ResultsSerum MDA levels correlated significantly with clinical short-term stroke outcome after 3 months (p< 0.001).Conclusion(s)These data provide evidence that the MDA (an oxidative stress biomarker) may be used as predictor for functional outcome in acute ischemic stroke.

PURPOSE To describe the incidence, relative risk, and risk factors for chronic comorbidities in survivors of adolescent and young adult (AYA) cancer. METHODS This retrospective cohort study included 2-year survivors of AYA cancer diagnosed between age 15 and 39 years at Kaiser Permanente Southern California from 2000 to 2012. A comparison cohort without cancer was individually matched (13:1) to survivors of cancer on age, sex, and calendar year. Using electronic medical records, all participants were followed through December 31, 2014, for chronic comorbidity diagnoses. Poisson regression was used to evaluate the association between cancer survivor status and risk of developing each comorbidity. The associations between cumulative exposure to chemotherapy and radiation therapy and selected comorbidities were examined for survivors of cancer. RESULTS The cohort included 6,778 survivors of AYA cancer and 87,737 persons without a history of cancer. The incidence rate ratio (IRR) for survivors of cancer was significantly increased for nearly all comorbidities examined. IRR ranged from 1.3 (95% CI, 1.2 to 1.4) for dyslipidemia to 8.3 (95% CI, 4.6 to 14.9) for avascular necrosis. Survivors of AYA cancer had a 2- to 3-fold increased risk for cardiomyopathy, stroke, premature ovarian failure, chronic liver disease, and renal failure. Among survivors of cancer, significant associations between chemotherapy and radiation therapy exposures and late effects of cardiomyopathy, hearing loss, stroke, thyroid disorders, and diabetes were observed from the multivariable analyses. Forty percent of survivors of AYA cancer had multiple (≥ 2) comorbidities at 10 years after index date, compared with 20% of those without cancer. CONCLUSION Risk of developing comorbidities is increased in survivors of AYA cancer compared with the general population. Specific cancer treatment exposures were associated with risk of developing different comorbidities. These findings have important implications for survivorship care planning and patient education.
Miraculous Evidence
Authors: Telliel Yunus Doğan 
Published: July 2020

AbstractSince the end of the nineteenth century, Muslims have pursued the idea that the Quran foreshadows new scientific discoveries. Linked to claims that the Quran's divine truth is continually substantiated, rather than disproved, by new scientific discoveries, certain verses are presented as Quranic miracles—evidence of its transcendent source. Drawing on ethnographic research with Turkish Muslims engaged in scientific exegesis, this article examines the evidentiary inquiry underlying the Quran's “scientific miracles” along two lines: first, it considers how these efforts, while invoking traditional understandings of the miraculous (i.e., arresting one in awed suspense), shift focus away from the Quran's stylistic and textual properties (requiring mastery of Arabic) and toward its signifying, universally accessible natural phenomena. Second, as the idea of scientific miracles befits apologetics typically used to defend the Quran against non-Muslims' criticisms, it asks why these efforts are directed primarily toward Muslims themselves. The article argues that the power of scientific miracles lies not only in the appeal of a universal language of evidence, but also in its use as a tool of “inner conversion,” which helps enable a modern refiguring of Muslim faith, from imitation (taqlid) to substantiation with evidence (tahqiq).

Authors: Menezes Raimundo Aurélio De , Miguel Joelson Rodrigues 
Published: July 2020

A importância da leitura e da escrita no cotidiano de todas as pessoas não merece retoques ou juízo de valor, independentemente do tempo ou do momento histórico. O ato de ler e escrever corretamente é o requisito mínimo que se exige de um cidadão na era contemporânea. O presente estudo discute a Ênfase nas Práticas de Leitura e Escrita no Ensino Fundamental. Trata-se de uma revisão integrativa cujo referencial teórico baseia-se nas propostas dos seguintes autores: Santos e Mendonça (2007), Vygotsky (21191 e 2008), que fundamentam os pressupostos do ensino e da aprendizagem, além das contribuições de Gasparin (2001) sobre a aprendizagem significativa e de Maia (2015) acerca da Psicolinguística e, Soares (2018) que aborda o campo de apropriação da escrita. Num tempo dominado pela tecnologia em que se apresentam novas versões e modos de leitura e de escrita, os usos desses instrumentos de comunicação pavimentam o caminho que vai possibilitar uma vida profissional e pessoal bem-sucedida. As plataformas de acesso à leitura e à escrita são múltiplas, desde a utilização do livro físico tradicional presente nas bibliotecas públicas e as escolares, dos livros gratuitos disponibilizados na internet, até ao e-book, um suporte da tecnologia para facilitar a vida dos leitores e assim, estimular o prazer pela leitura. Mesmo com todas essas facilidades, os processos de alfabetização e letramento no ensino fundamental, com ênfase na aprendizagem significativa em leitura e escrita, ainda representam um desafio para as políticas públicas no Brasil.

Marked and unmarked translanguaging in accelerated, mainstream, and sheltered English classrooms
Authors: Beiler Ingrid Rodrick 
Published: July 2020

AbstractTranslanguaging has gained prominence as a way to understand multilingual practices and draw on these in additional language teaching, but questions remain regarding its application in various educational contexts. This study investigates the significance of translanguaging across instructional settings by comparing discourses of markedness in accelerated, mainstream, and sheltered classes taught by the same teacher, where both linguistically majoritized and minoritized students were learning English as an additional language. Data are drawn from four months of linguistic ethnographic fieldwork at a Norwegian upper secondary school and include field notes, video and screen recordings, texts, language portraits, and teacher and student interviews. I found that translanguaging was marked in two largely separate ways: (1) bilingual English-Norwegian practices were more frequently marked in accelerated and mainstream settings, in relation to students’ perceived English proficiency level; whereas (2) translanguaging drawing on minoritized languages was more consistently marked in all three settings as a deviation from majority linguistic practices, thus distinguishingmajoritized(English-Norwegian) fromminoritizedtranslanguaging. Implications include the importance of analyzing translanguaging in relation to locally salient discourses and contextualizing pedagogical interventions in larger struggles for justice.
Analytic relations versus syntagmatic and paradigmatic relations of vocabulary depth knowledge: Their correlation and prediction to academic reading comprehension of EFL learners
Authors: Hasan Md Kamrul , Rahman Mohammad Mosiur 
Published: July 2020

AbstractThe aims of the study were to examine the correlation and prediction of different dimensions of vocabulary depth knowledge to academic reading comprehension. Students were instructed to take part in four English-language proficiency tests voluntarily. The research was carried out, administering four instruments, word associates test, morphological knowledge test, and analytic relations test to measure the depth of vocabulary knowledge. In addition, a reading comprehension test that consisted of three reading passages by Longman Test of English as a Foreign Language was adopted and administered for the current study. The results highlighted that the analytic (part–whole) relations, which represented the depth of vocabulary knowledge had the highest correlation with academic reading comprehension in comparison with morphological knowledge and combined syntagmatic and paradigmatic relations, which represented word associates test. Of all the three independent variables, analytical relations made the most statistically significant unique contribution to the prediction of the outcome variable compared to word associates test and morphological knowledge. The present study suggests that the depth of vocabulary knowledge would have practical use for students and English teachers at tertiary level and further implications for lexical researchers.
Fieldwork, Serendipity, and Ethiopian Women
Authors: Molvaer Reidulf K. 
Published: July 2020

Anthropologists are increasingly using sociological methods in fieldwork; but when doing research in cultures other than their own, this will often impoverish their investigation, as they do not know the most revealing questions to ask. By keeping an open mind, surprising information may unexpectedly turn up. This is, e.g., the case when investigating the situation of women, where it may be necessary to conduct studies in indirect ways, in combination with more factual statistical data collection.

Italy and Ethiopia: the Colonial Interlude Revisited
Authors: Sbacchi Alberto 
Published: July 2020

In 1997 the president of the Italian Republic visited Ethiopia and Eritrea to acknowledge the mistakes of Italian colonialism toward the people of the Horn of Africa. The theme of Italian colonialism in Ethiopia has long been an emotional one. However, in the last few years new archival resources have become available. The literature on the Italian occupation has become more objective and reliable. Hence there is a better appreciation of the Italian presence in Ethiopia, and the new generation is ready to admit Italy’s positive contribution. There are statistics on Italian investments in Ethiopia that show that Italy made the largest financial investment that Africa has ever seen. Considering those and other facts, the author of the paper attempts to reassess the issue of the Italian presence in Ethiopia, in all objectivity and on its own merits.

Detailed 3D Fault Representations for the 2019 Ridgecrest, California, Earthquake Sequence
Authors: Plesch Andreas , Shaw John H. , Ross Zachary E. , Hauksson Egill 
Published: July 2020

ABSTRACT
We present new 3D source fault representations for the 2019 M 6.4 and M 7.1 Ridgecrest earthquake sequence. These representations are based on relocated hypocenter catalogs expanded by template matching and focal mechanisms for M 4 and larger events. Following the approach of Riesner et al. (2017), we generate reproducible 3D fault geometries by integrating hypocenter, nodal plane, and surface rupture trace constraints. We used the southwest–northeast-striking nodal plane of the 4 July 2019 M 6.4 event to constrain the initial representation of the southern Little Lake fault (SLLF), both in terms of location and orientation. The eastern Little Lake fault (ELLF) was constrained by the 5 July 2019 M 7.1 hypocenter and nodal planes of M 4 and larger aftershocks aligned with the main trend of the fault. The approach follows a defined workflow that assigns weights to a variety of geometric constraints. These main constraints have a high weight relative to that of individual hypocenters, ensuring that small aftershocks are applied as weaker constraints. The resulting fault planes can be considered averages of the hypocentral locations respecting nodal plane orientations. For the final representation we added detailed, field-mapped rupture traces as strong constraints. The resulting fault representations are generally smooth but nonplanar and dip steeply. The SLLF and ELLF intersect at nearly right angles and cross on another. The ELLF representation is truncated at the Airport Lake fault to the north and the Garlock fault to the south, consistent with the aftershock pattern. The terminations of the SLLF representation are controlled by aftershock distribution. These new 3D fault representations are available as triangulated surface representations, and are being added to a Community Fault Model (CFM; Plesch et al., 2007, 2019; Nicholson et al., 2019) for wider use and to derived products such as a CFM trace map and viewer (Su et al., 2019).
