Published: December 2020

En este trabajo se presenta un estudio comparativo de la impedancia de un electrodo vertical enterrado en un suelo homogéneo donde los parámetros eléctricos (resistividad y permisibilidad) son dependientes de la frecuencia en relación a los mismos con parámetros constantes. Para su cálculo, es llevado en consideración que el electrodo vertical se puede interpretar como una línea de transmisión (LT) cuyos los parámetros eléctricos son distribuidos por unidad de longitud. Así, la impedancia del electrodo es computada como siendo la impedancia harmónica de LT en función de la frecuencia. Una vez obtenidas las impedancias de aterramiento del electrodo, y empleando una técnica de mínimos cuadrados, se las representan por circuitos eléctricos directamente en el dominio del tiempo. La ventaja de usar este tipo de representación es que el modelo puede insertarse fácilmente en software del tipo EMTP para el análisis de los transitorios electromagnéticos. Así, se calculan las elevaciones de potencial en el aterramiento para una descarga atmosférica incidente en el electrodo. Adicionalmente, una descarga atmosférica es inyectada en el topo de una torre de transmisión aterrada por un electrodo vertical, para evaluar las tensiones en los brazos de la estructura y en su base. Los resultados muestran que las tensiones son significativamente modificadas por la presencia del suelo con parámetros dependientes de la frecuencia, en especial las amplitudes, y que un análisis preciso del transitorio en los sistemas eléctricos debe llevar en cuenta ese fenómeno.

Authors: Cyr Andrée-Ann , Romero Kristoffer , Galin-Corini Laura 
Published: December 2020

Background
Web-based research allows cognitive psychologists to collect high-quality data from a diverse pool of participants with fewer resources. However, web-based testing presents unique challenges for researchers and clinicians working with aging populations. Older adults may be less familiar with computer usage than their younger peers, leading to differences in performance when completing web-based tasks in their home versus in the laboratory under the supervision of an experimenter.

Objective
This study aimed to use a within-subjects design to compare the performance of healthy older adults on computerized cognitive tasks completed at home and in the laboratory. Familiarity and attitudes surrounding computer use were also examined.

Methods
In total, 32 community-dwelling healthy adults aged above 65 years completed computerized versions of the word-color Stroop task, paired associates learning, and verbal and matrix reasoning in 2 testing environments: at home (unsupervised) and in the laboratory (supervised). The paper-and-pencil neuropsychological versions of these tasks were also administered, along with questionnaires examining computer attitudes and familiarity. The order of testing environments was counterbalanced across participants.

Results
Analyses of variance conducted on scores from the computerized cognitive tasks revealed no significant effect of the testing environment and no correlation with computer familiarity or attitudes. These null effects were confirmed with follow-up Bayesian analyses. Moreover, performance on the computerized tasks correlated positively with performance on their paper-and-pencil equivalents.

Conclusions
Our findings show comparable performance on computerized cognitive tasks in at-home and laboratory testing environments. These findings have implications for researchers and clinicians wishing to harness web-based testing to collect meaningful data from older adult populations.

Published: December 2020

Background
Rosacea is a chronic inflammatory disease with variable clinical presentations, including transient flushing, fixed erythema, papules, pustules, and phymatous changes on the central face. Owing to the diversity in the clinical manifestations of rosacea, the lack of objective biochemical examinations, and nonspecificity in histopathological findings, accurate identification of rosacea is a big challenge. Artificial intelligence has emerged as a potential tool in the identification and evaluation of some skin diseases such as melanoma, basal cell carcinoma, and psoriasis.

Objective
The objective of our study was to utilize a convolutional neural network (CNN) to differentiate the clinical photos of patients with rosacea (taken from 3 different angles) from those of patients with other skin diseases such as acne, seborrheic dermatitis, and eczema that could be easily confused with rosacea.

Methods
In this study, 24,736 photos comprising of 18,647 photos of patients with rosacea and 6089 photos of patients with other skin diseases such as acne, facial seborrheic dermatitis, and eczema were included and analyzed by our CNN model based on ResNet-50.

Results
The CNN in our study achieved an overall accuracy and precision of 0.914 and 0.898, with an area under the receiver operating characteristic curve of 0.972 for the detection of rosacea. The accuracy of classifying 3 subtypes of rosacea, that is, erythematotelangiectatic rosacea, papulopustular rosacea, and phymatous rosacea was 83.9%, 74.3%, and 80.0%, respectively. Moreover, the accuracy and precision of our CNN to distinguish rosacea from acne reached 0.931 and 0.893, respectively. For the differentiation between rosacea, seborrheic dermatitis, and eczema, the overall accuracy of our CNN was 0.757 and the precision was 0.667. Finally, by comparing the CNN diagnosis with the diagnoses by dermatologists of different expertise levels, we found that our CNN system is capable of identifying rosacea with a performance superior to that of resident doctors or attending physicians and comparable to that of experienced dermatologists.

Conclusions
The findings of our study showed that by assessing clinical images, the CNN system in our study could identify rosacea with accuracy and precision comparable to that of an experienced dermatologist.

Published: December 2020

Latin America accounts for roughly one-quarter of global COVID-19 cases
and one-third of deaths. Health inequalities in the region lead to
barriers regarding the best use of diagnostic tests during the pandemic.
There is a need for a simplified guideline in the region that takes into
consideration the available health resources, international guidelines,
medical literature, and local expertise.
Nine experts from different Latin American countries developed a
simplified algorithm for COVID-19 diagnosis in the region, using a
modified Delphi method. Twenty-four questions related to diverse
diagnostic settings were initially proposed, followed by an extensive
discussion of the literature and experts’ experience.
According to time from close contact or symptom onset, the algorithm
considers three different timeframes (≤7 days, 8–13 days, and ≥14 days)
and discusses diagnostic options for each one. SARS-CoV-2 real-time
reverse transcription polymerase chain reaction (rRT-PCR) continues to
be the diagnostic test of choice from Day 1 to Day 14 after symptom
onset or close contact, although antigen testing may be used in
high-prevalence settings or in particular situations (such as from Day 0
to Days 5–7 of symptom onset). Antibody assays may be used for
diagnostic confirmation, mainly after Day 14, if there is an
epidemiological or individual need. If the clinical suspicion is very
high, but other tests are negative, these assays may be used as an
adjunct to decision-making from Days 8–13.
The proposed algorithm is intended to be used as a support for COVID-19
diagnosis decision-making in Latin America.
Employee Satisfaction and Work-Life Balance in Accounting Firms and Audit Quality
Authors: Khavis Joshua A. , Krishnan Jagan 
Published: December 2020

SUMMARY
The PCAOB's audit-quality framework posits that superior inputs are essential for achieving high audit quality, and these inputs depend on the accounting firm's ability to recruit and retain quality personnel. However, the link between these inputs and audit quality has gone largely unexplored. We use employees' reviews of accounting firm employers from Glassdoor.com to examine perceptions of these inputs, and test whether accounting firms' internal characteristics explain employee satisfaction and audit quality. Our descriptive evidence suggests that “career opportunities,” “senior management,” and “culture and values” play a more important role in employees' satisfaction than do “compensation and benefits” or “work-life balance.” Although work-life balance is not among the most important factors that are associated with audit employees' job satisfaction, better work-life balance is nonetheless associated with higher audit quality. However, we do not find a significant association between audit-employees' job satisfaction and audit quality.

Purpose: comparison of hemodynamic parameters of transaortic blood flow in patients with aortic stenosis depending on the bivalve or tricuspid structure of the aortic valve.Materials and methods. A study of 180 patients with isolated aortic valve stenosis (AC) with two – and threeleaf structure was conducted. Patients were ranked into 3 comparison subgroups by the area of the effective AC opening from 4 to 1.5 cm2; 1.5 to 1 cm2 and less than 1 cm2. An echocardiographic study was performed with the calculation of all the necessary parameters for the study.Results. The comparison subgroups were comparable in terms of effective orifice area (AVA), effective orifice area index (IAVA), body mass index (BMI), LV UO index, and LV FV (p > 0.05). However, the indicators Vmax, Gmean, and AT in patients with a bivalve AK structure in all comparison subgroups were significantly higher than in patients with a tricuspid structure. Comparison subgroup with AVA from 4 to 1.5 cm2: Vmax 2.8 ± 9 m/s and 2.5 ± 6 m/s p = 0.02. Gmean 18.6 ± 7.2 mm Hg and 15 ± 6 mm Hg p = 0.03, AT 82 ± 12 ms and 70 ± 10 ms p = 0.002. Comparison subgroup with AVA from 1.5 to 1 cm2: Vmax 3.7 ± 0.8 m/s and 3.5 ± 0.6 m/s p = 0.02. Average transaortic gradient 37 ± 10 mm Hg and 29 ± 5 mm Hg p = 0.04, AT 103 ± 11 ms and 94 ± 10 ms p = 0.02. Comparison subgroup with an effective area of less than 1 cm2: Vmax 5.7 ± 1.2 m/s and 4.7 ± 0.7 m/s p = 0.001, Gmean 54 ± 15 and 43 ± 11 mm Hg p < 0.001, AT 127 ± 20 ms and 112 ± 10 ms p = 0.002.Conclusion.

Published: December 2020

The study empirically investigates the impact of managerial competency and learning orientation on job performance of individuals working in the software industry of Pakistan. Social skills have been introduced as a moderator alongside entrepreneurial leadership which acts as a mediator in both relationships. The data from 384 respondents, collected through survey, was analyzed using Structural Equation Modeling (SEM) through SmartPLS. The results suggested that managerial competency and learning orientation are positively related to job performance, and entrepreneurial leadership partially mediated the relationship of managerial competency and job performance, and learning orientation and job performance. Social skills moderate the relationship of managerial competency and job performance, while the moderating role of social skills was not found for the association of learning orientation and job performance.
To the best of our knowledge, this is the first investigation of its kind, incorporating technical and behavioral aspects (social skills) in a single framework. The study contributes to the existing literature by analyzing the impact of aforementioned relationships in the Pakistani organizational context. The study may present vital insights for organizations to prioritize development of managerial competencies, learning orientation, entrepreneurial leadership and social skills for improved job performance.

Published: December 2020

The present study investigates makerspaces in Nigerian academic libraries: perceived benefits and challenges. Four objectives guided the study: what constituted makerspace in academic library, the level of awareness of makerspace by academic library benefits and challenges of adopting makerspace in libraries. The descriptive survey design was adopted and questionnaire was used for data collection. The population of the study comprised of professional and paraprofessional librarians of Ambrose University and University of Benin, from which a sample size of 119 was drawn using total enumeration sampling technique. Out of the 119 copies of questionnaire administered, 94 were retrieved and analyzed using simple percentage and frequency tables. Findings revealed that, the respondents were aware of what constitute makerspace which are library space, 3D printers, computers and projector. It was also discovered that, the respondents had a high level of awareness of makerspace in the library. Some of the benefits associated with the use of makerspace are: it facilitates group interaction, it improves knowledge and provides access to wide varieties of tools and technology. Some of the challenges encountered in the adoption of makerspace are training of academic library staff, security of makerspace gadgets, poor funding, erratic power supply, high cost and maintenance of equipment. It was however recommended that; librarians should make deliberate effort to explore the potentials in makerspace in the enhancement of their services and training should be conducted regularly to enhance librarian’s skills in the use of ICTs.
