On the Problem of Quadrature Approximation of One Singular Integral Operator
Authors: Sanikidze J. 
Published: June 2020

AbstractA computational scheme for approximating a singular operator in the
known Lippman-Schwinger equations is suggested. It is based on partial use of Gaussian
knots. On the basis of studying the asymptotic properties of the solution and
one unclassical estimation of the accuracy of the Gaussian quadrature formulas, the
convergence of the scheme, with estimation of the rate of convergence, is proved. The
analysis of the computational aspects of the scheme is carried out and the results of
calculations of some test examples are given.
Does an Introduction of a Paid Parental Leave Policy Affect Maternal Labor Market Outcomes in the Short Run? Evidence from Australia’s Paid Parental Leave Scheme
Authors: Bass Brittany 
Published: June 2020

Abstract
This paper studies how an introduction of paid parental leave (PPL) affects maternal labor market outcomes in the short run. Using a reform in Australia, the PPL scheme, that gave the primary caregiver of a child born or adopted on or after January 1 2011, $672.70 a week for a maximum of 18 weeks, this paper develops theoretical predictions of the effect of PPL on maternal labor market outcomes, and tests these predictions using confidential data from the Australian Pregnancy and Employment Transitions Survey. The theoretical results imply that after the introduction of PPL, hours of work in the pre-birth period should decrease for mothers who will qualify for PPL, and increase for mothers who are attempting to qualify for PPL. Post birth, the theoretical results imply that more mothers are out of work and on leave than would have been in the absence of PPL. The empirical results suggest that the PPL scheme had no significant effect on labor market outcomes pre birth or post birth.

Published: June 2020

Abstract
Lungs are used as an attractive possibility for administration of different therapeutic substances for a long time. An innovative method of such administration widely studied nowadays is the application of aerosolized magnetic particles as the carriers to the lungs in the external non-homogeneous magnetic field. For these reasons we have studied dynamics of such a system on a level of particle trajectory in air in the presence of magnetic force as a driving force exerted on micrometric magnetic particle. On two typical examples of magnetically driven systems—motion of magnetic particle in a gradient magnetic field and cyclotron-like motion of a charged particle in homogeneous magnetic field in microscale, where the external accelerating forces are very large and the relevant time scale is of the order from fraction of milliseconds to seconds, we have examined the importance of these forces. As has been shown, for particles with high initial acceleration, not only the commonly used Stokes force but also the Basset history force should be used for correct description of the motion.

Published: June 2020

Abstract
The paper presents a matrix approach to the propagation of uncertainties in the realization of the ITS-90 using Standard Platinum Resistance Thermometers (SPRT) calibrated at Defining Fixed Points (DFPs). The procedure allows correlations to be included between SPRT resistances measured during the calibration at the DFPs (i.e., the realization of the ITS-90) and the resistances measured during the subsequent use of the SPRT to measure temperature T
90. The example also shows the possible contribution of these correlations to the overall temperature uncertainty measured by a calibrated SPRT.
Why some Fail and others Succeed: Explaining the Academic Performance of PA Undergraduate Students
Authors: Pavelea Alina Maria , Moldovan Octavian 
Published: June 2020

Abstract
The current research explores the influence of multiple factors (such as class attendance, previous academic performance, in-class involvement and attention, class schedule, gender and other control variables) on the academic performance of public-administration undergraduate students. The regression models developed based on the academic literature were tested on a sample of 1st-year students (N = 115) enrolled in the Public Administration bachelor program of Babeș-Bolyai University (Cluj-Napoca) in order to explain their performance (grade) in a final examination. Since none of the variables included in the model are self-reported (i.e. classic self-administered questionnaires) we have reduced the potential that social desirability bias could influence our results, thus strengthening the reliability and robustness of our findings.
Our results show that the main factors which can influence students’ academic performance are attendance at seminars and in-class involvement. All other factors which were included in the regression model (age, gender, distance between class site and their home, residence in urban or rural environment, attention and motivation, class schedule and four proxies / measures for previous performance) were either not statistically significant in any of the models or showed an inconsistent / unstable influence on academic performance.
These results can be of interest not only for Public Administration scholars, but also for university decision makers. As such, starting from the aforementioned findings and the literature, we also propose and discuss specific measures, which can be adopted by faculty-level decision makers in order to help students improve their academic performance and ensure better educational outcomes, especially in regard to the admission criteria currently in place.

Points for practitioners

The research investigates, among other potential factors, whether class attendance influences performance regardless of other individual characteristics. In doing so, the research tries to provide an answer to the ongoing debate on the usefulness of compulsory attendance at lectures and seminars in higher education. Furthermore, by observing the influence of previous performance (during high school) on current academic performance, the research can identify more adequate admission criteria, which can be used by university decision makers to ensure a better selection of candidates, thus potentially decreasing dropout rates.

Authors: Rizzatti Ivanise Maria , Sousa Joselma Soares Sousa 
Published: June 2020

A proposta da Educação Integral no contexto educacional brasileiro não é de hoje, e está sendo implantada gradativamente, com o intuito de oferecer para a população uma educação de qualidade. No entanto, a implantação do Ensino Médio em Tempo Integral (EMTI) já estava incluída no Plano Nacional de Educação entre uma das metas a serem alcançadas até 2024. Porém, essa nova modalidade traz muitos questionamentos sobre a sua implantação, principalmente em relação às disciplinas ditas não obrigatórias, bem como sobre a estrutura das escolas que estão recebendo essa nova modalidade. Com base na pesquisa documental e bibliográfica objetivou-se refletir sobre à Educação Integral no Brasil, diante desta conjuntura atual. E assim estaremos explanando um breve resgate histórico da “Educação Integral”, e o novo Ensino Médio, sendo a atual realidade nos estados brasileiros, inclusive em Roraima, diante da proposta atual de implantação do EMTI que teve início em 2017. Entretanto, ainda temos um grande desafio a ser percorrido diante da implantação do EMTI nas escolas públicas em todo o Brasil.

Published: June 2020

Objectives:
A home monitoring device (ForeseeHome; Notal Vision, Tel Aviv, Israel) detected choroidal neovascularization in age-related macular degeneration (AMD) earlier than home and office monitoring. This study describes device usage in routine clinical practice.

Materials and Methods:
An Institutional Review Board-approved retrospective chart review of intermediate AMD patients who used the device at a single tertiary care center. Primary outcomes were duration and frequency of usage and outcomes of alerts generated.

Results:
Sixty-two patients (106 eyes) completed monitoring 4.2 ± 2.1 times per week (avg ± std dev) from February 2015 to February 2019. Forty-five eyes discontinued monitoring after an average of 65 days (range 13–237 days), due to poor quality tests (62%), and false-positive alerts (16%). Eyes that discontinued device monitoring were older and had poorer visual acuity than eyes that continued monitoring (P < 0.01). Fourteen alerts were generated, of which one represented conversion to exudative AMD. Two additional converted eyes were identified by routine office visit and Amsler grid monitoring.

Conclusions:
Home monitoring has the potential to improve the detection of exudative AMD. Identifying barriers to device utilization are necessary in the AMD population.
Role of Computed Tomography-guided Biopsies in the Era of Electromagnetic Navigational Bronchoscopy: A Retrospective Study of Factors Predicting Diagnostic Yield in Electromagnetic Navigational Bronchoscopy and Computed Tomography Biopsies
Authors: Atkins Naomi K. , Marjara Jasraj , Kaifi Jussuf T. , Kunin Jeffrey R. , Saboo Sachin S. , Davis Ryan M. , Bhat Ambarish P. 
Published: June 2020

Objectives:
Over 25% of the high-risk population screened for lung cancer have an abnormal computed tomography (CT) scan. Conventionally, these lesions have been biopsied with CT guidance with a high diagnostic yield. Electromagnetic navigational bronchoscopy (ENB) with transbronchial biopsy has emerged as a technology that improves the diagnostic sensitivity of conventional bronchoscopic biopsy. It has been used to biopsy lung lesions, due to the low risk of pneumothorax. It is, however, a new technology that is expensive and its role in the diagnosis of the solitary pulmonary nodule (SPN) is yet to be determined. The purpose of this study was to evaluate the diagnostic yield of CT-guided biopsy (CTB) following non-diagnostic ENB biopsy and identify characteristics of the lesion that predicts a low diagnostic yield with ENB, to ensure appropriate use of ENB in the evaluation of SPN.

Materials and Methods:
One hundred and thirty-five lung lesions were biopsied with ENB from January 2017 to August 2019. Biopsies were considered diagnostic if pathology confirmed malignancy or inflammation in the appropriate clinical and imaging setting. We evaluated lesions for several characteristics including size, lobe, and central/peripheral distribution. The diagnostic yield of CTB in patients who failed ENB biopsies was also evaluated. Logistic regression was used to identify factors likely to predict a non-diagnostic ENB biopsy.

Result:
Overall, ENB biopsies were performed in 135 patients with solitary lung lesions. ENB biopsies were diagnostic in 52% (70/135) of the patients. In 23 patients with solitary lung lesions, CTBs were performed following a non-diagnostic ENB biopsy. The CTBs were diagnostic in 87% of the patients (20/23). ENB biopsies of lesions <21.5 mm were non-diagnostic in 71% of cases (42/59); 14 of these patients with non-diagnostic ENB biopsies had CTBs, and 86% of them were diagnostic (12/14). ENB biopsies of lesions in the lower lobes were non- diagnostic in 59% of cases (35/59); 12 of these patients with non-diagnostic ENB biopsies had CTBs, and 83% were diagnostic (10/12). ENB biopsies of lesions in the outer 2/3 were non-diagnostic in 57% of cases (50/87); 21 of these patients with non-diagnostic ENB biopsies had CTBs, and 86% were diagnostic (18/21).

Conclusion:
CTBs have a high diagnostic yield even following non-diagnostic ENB biopsies. Lesions <21.5 mm, in the outer 2/3 of the lung, and in the lower lung have the lowest likelihood of a diagnostic yield with ENB biopsies. Although CTBs have a slightly higher pneumothorax rate, these lesions would be more successfully diagnosed with CTB as opposed to ENB biopsy, in the process expediting the diagnosis and saving valuable medical resources.
Spinal dural arteriovenous fistula masquerading as subdural hematoma
Authors: Huntoon Kristin , Khandpur Umang , Dornbos David , Youssef Patrick P 
Published: June 2020

Background:
This case highlights an angiographically occult spinal dural AVF presenting with a spinal subdural hematoma. While rare, it is important that clinicians be aware of this potential etiology of subdural hematomas before evacuation.

Case Description:
A 79-year-old female presented with acute lumbar pain, paraparesis, and a T10 sensory level loss. The MRI showed lower cord displacement due to curvilinear/triangular enhancement along the right side of the canal at the T12-L1 level. The lumbar MRA, craniospinal CTA, and multivessel spinal angiogram were unremarkable. A decompressive exploratory laminectomy revealed a subdural hematoma that contained blood products of different ages, and a large arterialized vein exiting near the right L1 nerve root sheath. The fistula was coagulated and sectioned. Postoperatively, the patient regained normal function.

Conclusion:
Symptomatic subdural thoracolumbar hemorrhages from SDAVF are very rare. Here, we report a patient with an acute paraparesis and T10 sensory level attributed to an SDAVF and subdural hematoma. Despite negative diagnostic studies, even including spinal angiography, the patient underwent surgical intervention and successful occlusion of the SDAVF.

Published: June 2020

Background:Central nervous system involvement due to aspergillosis is an extremely serious entity, particularly in patients with severe neutropenia, hematological diseases, or post-transplant cases. Immunocompetent patients can be infected by intense exposure, particularly iatrogenic after invasive procedures.Case Description:We present the case of a 26-year-old male with a 1 year appendectomy background, which required epidural anesthesia. After that surgery, insidious headache presented, requiring mild analgesics for adequate control. In the following weeks, headaches increased and tomographic imaging revealed hydrocephalus. A ventriculoperitoneal shunt was placed, and empirical treatment for neurocysticercosis was established, but diagnosis was never confirmed. Sequentially, shunt dysfunction occurred twice, for which shunt replacement was performed. Cerebrospinal fluid and shunt’s catheter were cultured. Some days later, a filamentous fungus was isolated and finally identified asAspergillussp. Intravenous amphotericin B and fluconazole at therapeutic dosage were administered; however, a torpid clinical evolution was observed. After a 2-week antifungal scheme, the fungus was identified asAspergillus terreus. The patient developed sudden rostrocaudal deterioration. Computed tomography imaging was done, revealing a 70 cc hematoma in the right operculoinsular region, midline shift, and a 9 mm saccular aneurysm at the bifurcation of the middle cerebral artery.Conclusion:Cerebral aspergillosis is a serious disease with high mortality in patients, particularly those without identifiable risk factors. The iatrogenic forms are serious, due to the delay of clinical diagnosis. It is important to have a high index of suspicion in patients with a history of invasive procedures such as epidural anesthesia or surgery, and who develop a persistent chronic headache or chronic meningitis.

Background
The Canadian National Vaccine Safety (CANVAS) network monitors the safety of seasonal influenza vaccines in Canada.

Aim
To provide enhanced surveillance for seasonal influenza and pandemic influenza vaccines.

Methods
In 2017/18 and 2018/19 influenza seasons, adults (≥ 15 years of age) and parents of children vaccinated with the seasonal influenza vaccine participated in an observational study using web-based active surveillance. Participants completed an online survey for health events occurring in the first 7 days after vaccination. Participants who received the influenza vaccine in the previous season, but had not yet been vaccinated for the current season, were unvaccinated controls.

Results
In 2017/18, 43,751 participants and in 2018/19, 47,798 completed the online safety survey. In total, 957 of 30,173 participants vaccinated in 2017/18 (3.2%; 95% confidence interval (CI): 3.0–3.4) and 857 of 25,799 participants vaccinated in 2018/19 (3.3%; 95% CI: 3.1–3.5) reported a health problem of sufficient intensity to prevent their normal daily activities and/or cause them to seek medical care (including hospitalisation). This compared to 323 of 13,578 (2.4%; 95% CI: 2.1–2.6) and 544 of 21,999 (2.5%; 95% CI: 2.3–2.7) controls in each respective season. The event rate in vaccinated adults and children was higher than the background rate and was associated with specific influenza vaccines. The higher rate of events was associated with systemic symptoms and migraines/headaches.

Conclusion
In 2017/18 and 2018/19, higher rates of events were reported following seasonal influenza vaccination than in the pre-vaccination period. This signal was associated with several seasonal influenza vaccine products.

The cognitive map and the use of names
In this paper, the author attempts to provide a general summary of the relationship between the cognitive map and spatial concepts on the one hand, and between the onomasticon related to the cognitive map and discourses about space on the other hand, focusing on universal as well as culturally specific features. To this end, the author summarizes and interprets all the relevant results of national and international research from the areas of geography, socio-geography, anthropology, psychology, socio-onomastics and cognitive linguistics. Space is made up of different places and their relationships, which are represented on the cognitive map. At the same time, the development of the cognitive map is governed by many factors. In addition to one’s own experiences of the geographical environment. A significant proportion of geographic knowledge also results from different sources or from a combination of sources. In this context, the linguistic-cultural background also influences the individual’s geographical concepts and spatial cognition. At the same time, there are general features, organizing principles in spatial cognition resulting from the mechanisms of cognition, which influence the development of the mental map and name-giving practices as well. A good example is that one can only define a place in relation to another place, and this relation is often reflected in place names. Closely connected to this, is the view of centre-periphery relations in space, which is often manifested in discourse about places and sometimes in the meanings of place names, as well. The connotative meaning attached to words can also be mentioned as a common feature, and this is present both in the organization of discourse about space and in place names. These interrelated principles may apply in different ways to different areas, communities and cultures.
