Entropy-Based Quantification of Privacy Attained Through User Profile Similarity
Authors: Jagwani Priti , Kaushik Saroj
Published: June 2021

Location-based services refer to services that use location as primary input. But accessing user's location by an adversary invites issues of privacy breach. Instead of specific location coordinates, its surrounding area known as cloaking region is revealed in order to get the service. K anonymity technique of location privacy ensures that at least K-1 users should be included within a specific cloaked region. Researches have established that on combining K anonymity with the idea of including similar users together in a cloaked region provides stringent privacy (especially from background and heterogeneity attacks). This work quantifies the amount of privacy gain attained through, opting-for users with similar profiles instead of random users. The quantification is done by using KL divergence. Values of KL divergence of user profiles have been calculated for different cloaking regions containing similar and random users. Low KL divergence values depict privacy gains up to 33% for users with similar profiles.
VerSA

Published: June 2021

The advent of the internet of things (IoT) and augmented reality technology not only introduces a wide range of security risks and challenges but also increases traffic on the existing wireless communication networks. This is due to the enormity of the traffics generated by the connected IoT devices whose number keeps increasing. Therefore, any IoT network requires an effective security solution capable of securing data and minimizing traffic on the IoT networks. To address these, the authors propose a practicable secure data aggregation scheme, VerSA, based on data grouping aggregation, batch verification through the aggregated signature ratios, and symmetric encryption with a pairing free key distribution. The scheme is capable of grouping and aggregating sub-network data into homogeneous and heterogeneous groups, detecting and filtering injected false data. The results show that the proposed scheme is not only secure against IoT related attacks but also has the lowest computational and communication overheads compared to the recent state-of-the-art schemes.
Bridging the Theory-Practice Gap
Authors: Jacobs Naomi , Wijnand IJsselsteijn
Published: June 2021

Many of the choices that designers and engineers make during a design process impact not only the functionality, usability, or aesthetics of a technology, but also impact the values that might be supported or undermined via the technology design. Designers can actively design for values, and this awareness has led to the development of various ‘ethics by design' approaches. One such approach is capability sensitive design (CSD). Thus far, CSD is only developed from a theoretical-ethical point of view. This article aims to bridge the theory-practice gap by entering into dialogue with various design-experts on ethics by design in general and CSD in particular. An empirical study, consisting of thematic interviews with nine design-experts, was conducted in order to explore design-experts' experiences with designing for values, what they regard as the strengths and weaknesses of CSD, and if CSD could be of practical use to their design (research) practice.
Value-Sensitive Design of Unmanned Aerial Systems
Authors: Andersen Tabitha , Cawthorne Dylan
Published: June 2021

What happens when an engineer attempts to address the value-neutral paradigm and the holistic deficits in engineering science? This paper sets out to account for the interplay between an unmanned aerial system engineer acting as a “champion” of value sensitive design (VSD) and their more objectivist research organization. Action research methods are used by the authors in an attempt to implement VSD in a real-world research organization and thereby bridge the theory-practice gap. Primary empirical data are collected which indicate the engineer has internalized and often utilizes a VSD approach. Both barriers and catalysts to wider adoption of VSD within the organization are experienced, and recommendations for overcoming paradigmatic, strategic, structural, and cultural barriers are addressed. This work demonstrates how action research can be used to shift engineering away from a value-neutral paradigm towards the value-sensitive approach advocated by the authors.
Designed to Seduce
Authors: Tollon Fabio
Published: June 2021

Up to 70% of all watch time on YouTube is due to the suggested content of its recommender system. This system has been found, by virtue of its design, to be promoting conspiratorial content. In this paper, the author firstly critiques the value neutrality thesis regarding technology, showing it to be philosophically untenable. This means that technological artefacts can influence what people come to value (or perhaps even embody values themselves) and change the moral evaluation of an action. Secondly, he introduces the concept of an affordance, borrowed from the literature on ecological psychology. This concept allows him to make salient how technologies come to solicit certain kinds of actions from users, making such actions more or less likely, and in this way influencing the kinds of things one comes to value. Thirdly, he critically assesses the results of a study by Alfano et al. He makes use of the literature on affordances, introduced earlier, to shed light on how these technological systems come to mediate our perception of the world and influence action.
A Method for Rapid Ethical Deliberation in Research and Innovation Projects
Authors: Steen Marc , Neef Martijn , Schaap Tamar
Published: June 2021

There are many and diverse methods available that can help researchers, designers, developers, and engineers integrate ethics in their research and innovation projects. In practice, however, they can find this challenging. They may believe that such methods are difficult and time-consuming, or that ethics hinders innovation and creativity. Borrowing from various methods, the authors created a lightweight method that researchers and designers can use to integrate ethics in their projects: rapid ethical deliberation. This research collaborated with four projects to assess this method in practice. The authors found that this method helped project team members in several ways: to envision the innovations they work in very practical terms; to look at these innovation from different normative, ethical perspectives; to look at their projects with fresh eyes and engage in creative and strategic thinking; and to articulate critical questions and associated actions to move their projects forward.
OAKESHOTT E IL RAZIONALISMO IN POLITICA
Authors: Giorgini Giovanni
Published: June 2021

L’attacco al razionalismo in politica costituisce il fulcro degli interessi teorici, e delle preoccupazioni pratiche, di Oakeshott negli anni Cinquanta. Con il termine razionalismo egli intende il supposto uso senza vincoli e senza pregiudizi della ragione e la fede che in questo modo si arriverà a un sicuro miglioramento della condizione umana. Nella sua ricostruzione, il primo autore a proporre l’uso della ragione, acuminata dal metodo induttivo e purificata da pregiudizi, come strumento della conquista della natura da parte dell’uomo fu Francis Bacon; una ragione strumentale che aveva fatto tabula rasa dei pregiudizi derivanti dalla società, dal principio di autorità, dalle opinioni comuni (i vari tipi di idola).
Evaluation of Novel co-processed excipient for fast disintegration of aspirin tablet formulations
Authors: Olayemi Olubunmi J. , Nock-Anyebe Sophie
Published: June 2021

Co-processing is a technique that ensures sub-particulate interaction of individual excipients leading to overall functionality of the resulting excipient. The aim of this study is to co-process Cyperus esculentus starch with mannitol by fusion and evaluate its effect on tablet disintegration and in vitro dissolution. Co-processed excipients were prepared from Cyperus esculentus starch and mannitol by fusion in ratios of 1:1, 1:2 and 2:1 (CM1, CM2, and CM3 respectively) and evaluated for flow and swelling properties. The excipients were incorporated into Aspirin tablet formulations at 5 %w/w by direct compression (FM1, FM2, FM3 respectively). Similar tablets were prepared using sodium starch glycolate (FSG) and the formulations were assessed for hardness, friability, wetting time, disintegrationtime and in vitro dissolution profile. All the prepared excipients possessed excellent flow with Carr’s index between 17.31 and 20.78 and Hausner ratio between 1.21 and 1.26. CM3 had the highest swelling profile (1.491) while CM2 had the lowest (1.321). Formulation FM1 had the highest tensile strength (14.12 N/cm2 ) but slower wetting time (34.33 sec) compared to FM3 with tensile strength of 11.32 N/cm2 and wetting time of 9.00 sec. Disintegration time of CM3 (4.26 min) was comparable to that of FSG (4.01 min); their dissolution profile was also found to be similar. Coprocessing Cyperus esculentus starch and mannitol by fusion (2:1) influenced tablet  disintegration and in vitro dissolution and has potential to be used in manufacture of fast dissolving tablet formulations.

Published: June 2021

The incidence and prevalence of cancer has been on the rise in recent years and this has been linked to environmental factors, adoption of westernized lifestyle and aging populations. This situation is further complicated by the inadequacies of currently used anticancer agents such as toxicity and resistance which has prompted the search for new and more effective drugs. In this study, Schiff bases of 5-aminotetrazole were prepared by condensing 5- aminotetrazole with various aromatic aldehydes. Preliminary confirmation of compound formation was done using thin layer chromatography while FT-IR, UV-Visible, proton and carbon-13 NMR spectroscopy were used for structural characterization of the compounds. The cytotoxicity of the compounds was evaluated using the brine shrimplethality assay. The compounds were synthesized in good yield ranging from 80 to 88 % and found to be soluble in polar solvents. Results of the spectroscopic analyses were indicative of the formation of the new compounds. The 5- aminotetrazole Schiff bases were found to demonstrate considerable cytotoxicity compared to the standard drug used, with the o-vanillin Schiff base (OVASB) showing the highest cytotoxicity (LC50 0.23 µg/mL). The results indicate that the compounds have potential for further development in the search for safe and potent anticancer agents.

An analytical solution for one-dimensional contaminant transport in a double-layered contaminated soil with imperfect diffusion boundaries
Authors: Li Xibin , Sheng Jianchao , Zhang Zhiqing , Wang Zhe
Published: June 2021

An analytical method is proposed to solve the contaminant transport in a double-layered contaminated soil with imperfect diffusion boundaries. By virtue of the separation of variables scheme, the governing equation for contaminant diffusion is split into two ordinary differential equations, and the corresponding general solutions are obtained. By utilizing the initial, continuity and boundary conditions of the system, and the orthogonality of trigonometric functions, the analytical solution for contaminant concentration in the double-layered contaminated soil is derived, which can be further used to describe the average degree of diffusion. The reliability and accuracy of the developed solution is verified by comparing with the existing analytical solution and numerical simulation results. Selected numerical examples are further presented to analyze the influence of the imperfect diffusion boundaries on the spatial/time distribution of contaminant concentration, average degree of diffusion and mass flux. The results show that greater imperfect diffusion capacity coefficients lead to lower contaminant concentration distribution within the entire depth range and higher average degree of diffusion for a given time. Particularly, it only takes 23.32 years to complete the entire diffusion process when imperfect diffusion capacity coefficients are infinite. The developed solution can provide useful guidance for engineering practice.
Effects of the carbon nanotube and polymer amounts on ultrafiltration membranes
Authors: Celik Madenli Evrim , Ilkay Ciftci Zeliha
Published: June 2021

Composite membranes with nano-sized inorganic materials have high selectivity, high hydrophilicity, and improved fouling resistance. Blending Carbon Nanotubes (CNTs) in the polymer solution improves membrane properties like hydrophilicity, water permeability, selectivity, and fouling resistance. The effect of the polymer amount, together with the CNT amount in the polymer solution on membrane properties, was investigated in this work. There was more than 10% increase in the hydrophilicity of the membranes with 1% CNT addition, but it was not altered with the polymer amount. The porosity was increased almost 30% by 1% CNT addition in membranes prepared by 10% and 12% polymer concentration (P-10:C-0 and P-12:C-0), but only 16% increase in porosity occurred in membrane prepared by 15% polymer concentration (P-15:C-0). The flux of the P-15:C-0 membrane was increased four times by 1% CNT addition. Besides, fouling resistance of the membranes decreased with increasing polymer amount but increased with increasing CNT amount. BSA rejection increased with increasing polymer amount or CNT amount in the polymer solution. Hence membranes prepared with a higher amount of polymer are more prone to membrane property improvements with CNT addition. The increase in flux and selectivity by CNT addition in all membranes prepared with different polymer concentrations will increase the membrane life-time and reduce the treatment cost.
Michael and other archangels behind an eight-pointed cross-symbol from Medieval Nubia: A view from Sai Island in northern Sudan
Authors: Hafsaas Henriette , Tsakos Alexandros
Published: June 2021

The Christian population in Medieval Nubia created numerous manifestations of their faith in various forms – from monumental cathedrals to minuscule inscriptions. Among the latter are monograms, cryptograms, and cross-shaped symbols. Researchers of Medieval Nubia have only seldom studied closely these epigraphic categories. Moreover, the study of the cult of the archangels, especially of the archangel Michael, who held a primal position in the belief system of Christians in Nubia, has only recently attracted the attention of Nubiologists. This article employs theory about the interface between the written and the visual in order to discuss grapho-linguistic evidence for this type of epigraphic devices and the use of such devices as multivocal symbols in the cults of the archangels in Medieval Nubia. A careful analysis of cryptograms of the archangels Michael and Raphael offers a key to the decipherment of an eight-pointed cross as a multivocal symbol connected with the cult of the archangels. The study pivots around observations made during fieldwork on Sai Island in northern Sudan.
Ben Ngobeni’s cosmo-dramas of the Afrofuture
Authors: Monoa Thabang
Published: June 2021

The print series entitled Bridge of the Spirits (2017) by visual artist Ben Ngobeni is redolent with depictions of “the cosmos” or outer-space. In this series, the bull is a prominent motif as it is represented literally and in some works, indirectly. The bull, as we may know, is central to many cultural rituals in different African societies. Ngobeni’s metaphorical use of this animal is resonant with Afrofuturist visual tropes that often employ space allegories. Yet it also invokes what jazz musician and Afrofuturist Sun Ra refers to as cosmo-drama. When coining this term, Sun Ra was alluding to the sense of otherworldliness he sought to achieve by staging cosmo-dramas, that is, spaces that were meant to “awaken their audiences to the greater potentials of another kind of life” (Youngquist, 2017:204). Cosmo-drama is here a fitting description of the type of themes engaged with in this body of work. This article is orientated around the notion of cosmo-drama to locate, on the one hand, the Afrofuturist proclivities in Ngobeni’s work, which are found visually. On the other hand, it seeks to understand how these supposed Afrofuturist proclivities are informed by aspects of ancestry.

Published: June 2021

This paper examines the efficiency of the thirty-six commercial banks (27 Domestic and 9 Foreign Banks) by reviewing Literature and analyzing 6 years (2011-2016) data. The sample was selected based on the availability of data.  It is assumed that the banking sector complies with the variable returns to scale (VRS) approach which means the output of a bank is not proportionately related to its inputs. Therefore, VRS in the ‘Data Envelop Analysis (DEA)’ technique has been employed in this paper. The findings reveal that most (30 banks out of 36 banks) of the banks of Bangladesh are inefficient in terms of technical, allocative, and scale efficiency during the 2011-2016 periods. Conversely, only six banks (4 domestic banks and 2 foreign banks) were found efficient in overall scores in this scrutinization. This study did not find any single bank as efficient in all categories (allocative efficiency, technical efficiency, pure efficiency ratio) for the whole study period (2011-2016). This paper provides valuable intuition, analysis, and comments to the managers and policymakers of the bank’s efficiency score so that they comprehend their position. Finally, this paper suggests necessary steps to transform the inefficient banks into efficient banks, and to make stable the banking sector of Bangladesh.

Mastitis je upalna reakcija organizma na infekciju sekretornog dijela mliječne žlijezde. Uzročnici mastitisa dijele se bojanjem po Gramu na Gram-pozitivne i Gramnegativne; prema etiologiji na kontagiozne i uvjetovane uzročnike. Kontagiozni se uzročnici najčešće prenose tijekom mužnje i prouzroče dugotrajne, kronične mastitise, uglavnom subkliničkog tijeka. Za razliku od njih, uvjetovani uzročnici u pravilu izazivaju kratkotrajne infekcije, ali s češćim kliničkim manifestacijama. Inficirane se krave otkrivaju dijagnostikom mastitisa, koja se najčešće provodi neizravnim ili izravnim metodama određivanja broja somatskih stanica i bakteriološkom pretragom mlijeka.Zagrebački mastitis test je brza i jednostavna orijentacijska metoda u procjeni broja somatskih stanica koji se provodi u terenskim uvjetima. Somatske stanice čine epitelne stanice i leukociti. Nalaze se u mlijeku, ali se njihov broj i odnos mijenja ovisno o upalnim promjenama u mliječnoj žlijezdi. Kretanje broja somatskih stanica uglavnom ovisi o pojavi mastitisa, ali i o stadiju laktacije, životnoj dobi životinje, godišnjem dobu, ali i ostalim bolestima mliječne krave. Mlijeko s povećanim brojem somatskih stanica ima promijenjenu kakvoću. Mlijeko sadrži niži udio mliječne masti i laktoze, a povećan je i udio proteina i električna provodljivost zbog povišene koncentracija klora i natrija u mlijeku. Osim toga, mlijeko ima i smanjenu termostabilnost te mu je smanjena sposobnost podsiravanja i formiranja gruša. Takvo mlijeko ima užegli okus i nije pogodno za proizvodnju kondenziranog mlijeka, mlijeka u prahu i steriliziranog mlijeka. Rok trajanja sireva proizvedenih od takvog mlijeka zbog zadržavanja veće količine vode je smanjen. Pravilnim i redovitim provođenjem postupaka dezinfekcije sisa vimena prije i poslije mužnje poboljšava se prinos i kakvoća mlijeka, odnosno smanjuju se troškovi liječenja mastitisa, a povećava se i prihod farme.

Published: June 2021

The complete Cytchrome b gene and partial mtDNA control region were sequenced for the Pakistani domestic yak (Bos grunniens) within the Bovidae family. A total of 300 samples were genotyped using 27 bovine microsatellite markers from the Gilgit-Baltistan and Skardu regions of Pakistan. We identified a total of 35 mutations and 9 haplotypes based on D-loop sequences, with a haplotype and nucleotide diversity of 0.9640±0.051 and 0.02172±0.00224, respectively. For the Cyt b gene, a total of 23 variable sites and six different haplotypes were observed with 0.885±0.067 haplotype and 0.00989±0.003 nucleotide diversity. Phylogenetic analysis of D-loop and Cyt b gene suggested that domestic yak sequences cluster into two highly divergent maternal lineages (lineages I and II), while three haplogroups A, C, and D were identified of the six previously known haplogroups. Haplogroups A and C were dominant and widely distributed among all investigated yak samples. All microsatellites were polymorphic and a total of 138 alleles were observed, with average polymorphic information content (PIC) of 0.56 indicating their effectiveness. The average heterozygosity was observed at 0.6071 with allele diversity of 5.1111 and gene diversity of 0.4830. The implications of these findings can be applied for yak conservation.

Published: June 2021

The aim of this study is to empirically analyze the relationship between accounting information quality and firm performance of oil and gas companies in Nigeria. Time series data on different types of accounting information quality and earnings per share from 2009-2018 were collected from central bank of Nigeria statistical bulletin, annual central bank of Nigeria reports, National Bureau of statistic and Federal Inland Revenue Service. Ordinary Least Square regression analysis, Autoregressive Distribution Lag, Co-integration, Augmented Dickey-Fuller Unit root test, Serial Correlation and Heteroskedasticity test and Error Correction model with the aid of E-view version 10. The empirical results indicate that accounting information quality significantly relate to firm performance; explaining abut 83.1% of total variation in earnings per share, audit lag and disclosure quality were each found to significantly relate to earnings per share. We therefore conclude that accounting information quality ahs the potency to make significant contribution to earnings per share and recommends that increased scrutiny by regulators (FRCN, CBN, SEC etc) over accounting flexibilities would help to curtail accounting discretions both deliberate and systematic so that accounting information in financial statements will faithfully represent the phenomena they purport to represent and future corporate scandals on oil and gas crises can be avoided.
The influence of content and non-content cues of tourism information quality on the creation of destination image in social media: A study of Khyber Pakhtunkhwa, Pakistan
Authors: Ali Danish , Xiaoying Liu
Published: June 2021

This research examines the Content Cues (CC) and Non-Content Cues (NCC) of tourism Information Quality (IQ) in social media (e.g., Instagram, Twitter, Facebook) and its influence on creating Destination Image (DES) components i.e., “cognitive image (COG), affective image (AF), conative image (CON)” in the scope of Khyber Pakhtunkhwa (KP), Pakistan. We distributed 500 questionnaires at various tourist destinations, and 446 complete questionnaires were returned and use for further analysis. We use the Confirmatory Factor Analysis (CFA) and Structural Equation Modelling (SEM) to get the research outcomes. Our outcome suggests that CC and NCC of tourism IQ are significantly related to the COG and AF, which leads to the CON. Our finding also identified the relationship between CC and NCC with CON through the mediation role of COG and AF, which were positive and significant. This research extends the insight of tourism IQ in social media, precisely the contextual dimension of IQ, by providing empirical evidence. This research also helps the KP Destination Marketing Organizations (DMO’s) to develop their marketing strategies to encourage more visitors by utilizing Social Media (SM) platforms to their destinations.
Green Synthesis of Gold Nanoparticles using Pimenta dioica Leaves Aqueous Extract and Their Application as Photocatalyst, Antioxidant, and Antibacterial Agents
Authors: Fadaka Adewale , Aluko Olukemi , Awawu Saartjie , Theledi Karim
Published: June 2021

Green synthesis of gold nanoparticles (AuNPs) is of particular interest due to their catalytic, antioxidant, and antibacterial properties. In this study, the aqueous extract of Pimenta dioica leaves was used to synthesize AuNPs and the effective parameters were investigated. The prepared AuNPs were characterized by various techniques including UV–Vis absorption spectroscopy, Fourier Transform Infrared (FTIR) spectroscopy, Transmission Electron Microscopy (TEM), and X-ray diffractometer (XRD). The reduction and stabilization effect of the plant extract to fabricate AuNPs were explained by FTIR analysis. TEM imaging confirmed the formation of spherical-shaped AuNPs. The catalytic activity of synthesized nanoparticles was evaluated in the degradation of a Methylene Blue dye in the presence of NaBH4 as reducing agent and achieved after only two minutes. The AuNPs provided high antioxidant ability. In addition, the synthesized AuNPs showed a significant inhibitory effect against both gram-positive and gram-negative bacteria, where the zone of inhibition of 4 and 9 mm were obtained for synthesized AuNPs against S. aureus and E. coli, respectively.
Modern research on the extraction of biologically active substances from plant raw materials using enzymes
Authors: Fabritskaya A. A. , Semenikhin S. O. , Gorodetsky V. O. , Kotlyarevskaya N. I. , Victorova E. P.
Published: June 2021

The article overviews modern studies of domestic and foreign scientists in the field of extraction of biologically active substances from plant materials using enzymes. Extraction of biologically active substances using enzymes allows for controlled biotransformation of plant materials due to the precise specificity and selectivity of enzymes, which creates mild conditions that ensure the preservation of biologically active substances. It has been noted that the quality of the extractant used has a significant effect on the efficiency of the extraction process. Thus, raw materials treated with a combination of an electrolyte and an enzyme are extracted more efficiently by reducing the mass transfer barrier. The main advantage of using supercritical fluids as an extractant is a decrease in temperature or pressure that leads to the precipitation of the extractable substance. One of the main disadvantages of the process of extracting biologically active substances from plant materials using enzymes is their high cost. To eliminate this disadvantage, the following intensification methods are used: ultrasonic treatment, high pressure treatment and microwave treat- ment. The most promising methods for intensifying the process of extracting biologically active substances from plant materials using enzymes are methods of ultrasonic and microwave treatment. Ultrasonic treatment under optimal conditions allows increasing the activity of enzymes, and microwave treatment provides more efficient penetration of the extractant into the tissues of plant material, due to the destruction of cell walls.

Было выяснено, что если ранее артисты-исполнители сами определяли и контролировали свою аудиторию, необходимости в особой правовой охране их интересов не было, то с появлением и бурным развитием радио, телевидения, средств звуко- и видеозаписи, материальных носителей информации и сети Интернет, ситуация изменилась. Доказана актуальность проблемы международно-правовой охраны смежных прав. Автором были рассмотрены особенности развития компьютерных и Интернет-технологий в контексте правового регулирования смежных прав.

Патоморфоз печени при острой постгеморрагической ишемии
Authors: Абдувалиева Чулпоной
Published: June 2021

Изучение механизмов организации и компенсации структуры и функции печени имеет важное практическое значение для разработки новых способов коррекции различных патологических состояний. В частности, у больных циррозом применение методов воздействия на процессы регенерации печени целесообразно как для лечения самого заболевания и его осложнений, так и для подготовки к ортотопической трансплантации печени. Анализируя полученные морфологические данные, авторы заключают, что кровотечение не является безразличной ситуацией для морфофункционального состояния печени. Сложившиеся неадекватные условия для печени при постгеморрагической ишемии в конечном итоге заставляют ее клетки и сосудистые структуры адаптироваться. Особая роль в приспособлении организма к этим условиям принадлежит системе микроциркуляции, которая несет ответственность за обеспечение метаболизма в тканях и гемодинамический гомеостаз.

Deep Learning Approach in Brain Tumor Classification
Authors: A Bhavani Sankar , K Suryavarshini
Published: June 2021

Various Computer-Aided Diagnosis (CAD) systems have been recently used in medical imaging to assist radiologist about their patients. Generally, various image technique such as Computer Tomography (CT), Magnetic Resonance Imaging (MRI) and ultrasound image are used to evaluate the tumor in a brain, lung, liver, breast, prostate etc., Especially, in this work MRI images are used to diagnose tumor in the brain. For full assistance of radiologists and better analysis of Magnetic Resonance Imaging, classification of brain tumor is essential procedure. The automatic classification scheme is essential to prevent the death rate of human. Deep learning is the newest and the current trend of machine learning field that paid a lot of the researchers’ attention in the recent few years. As a proven powerful machine learning tool, deep learning was widely used in several applications for solving various complex problems that require extremely high accuracy and sensitivity, particularly in the medical field. Tumor regions from an MR images are segmented using a deep learning technique. The automatic brain tumor classification is very challenging task in large spatial and structural variability of surrounding region of brain tumor. In this work, automatic brain tumor detection using Convolutional Neural Networks (CNN) classification. In general, brain tumor is one of the most common and aggressive malignant tumor diseases which is leading to very short expected life if it is diagnosed at higher grade. The deeper architecture design is performed by using small kernels. Other performance measures used in this study are the accuracy, sensitivity and specificity.
Um estudo sobre as práticas educativas de mediação de conflitos na orientação educacional
Authors: Lenz Adriana Janice , Viegas Moacir Fernando
Published: June 2021

O presente artigo tem como objetivo descrever, analisar e explicar as práticas educativas de mediação de conflitos das orientadoras educacionais. A discussão se justifica pelos limites da produção teórica sobre o tema e pelas contribuições às práticas de mediação em que estão envolvidos profissionais da educação, alunos e familiares de alunos. O estudo apoiou-se no materialismo histórico e dialético, em elementos conceituais e históricos sobre os conceitos de mediação e de conflito e, por fim, em contribuições de autores do campo da orientação educacional. Metodologicamente, utilizou-se de entrevistas semiestruturadas realizadas com quatro orientadoras educacionais que, no momento da pesquisa, trabalhavam em escolas públicas. Os resultados são apresentados em quatro categorias de análise: a) formação e experiência, onde é discutida a ausência de práticas educativas específicas sobre a atuação profissional das orientadoras, além do exíguo material teórico disponível; b) organização e divisão do trabalho, onde fica clara a reprodução da divisão do trabalho capitalista na prática dessas educadoras; c) práticas educativas de mediação de conflitos, onde se descreve a complexa trama de atividades realizadas por essas trabalhadoras e d) identidade profissional, tópico onde são abordados os dilemas advindos dos muitos papéis que elas desempenham.
Escritas de vida como possibilidade de resistência
Authors: Guida Angela , Almeida Machado Daniel , Yadira Bidemi Betinha
Published: June 2021

Busca-se, com este artigo, engendrar reflexões acerca da narrativa epistolar como uma categoria de escrita de vida, na qual hibridez e fluidez são características importantes para o que se pretende discutir aqui -   possibilidades de escritas de vida agirem como potência de escritas coletivas e a amplitude da narrativa epistolar no campo das narrativas literárias. Assim, o objetivo central aqui é discutir escritas de vida que se deslocam da intimidade para a coletividade e se oferecem como uma política de resistência, de modo especial, para se pensar o feminismo interseccional e Letter to my daughter (2008), de Maya Angelou, configura-se como um significativo exemplo desse tipo de narrativa, conforme se demonstrará ao longo deste artigo.
"A Fish in a Stream": on body and memory in Virginia Woolf’s “A Sketch of the Past”
Authors: De Carvalho Mesquita Ana Carolina
Published: June 2021

This article examines the deadlocks foregrounded in recreating and reconstituting memory in Virginia Woolf’s “A Sketch of the Past” from the body’s perspective. “Body” is seen here as a category to reflect upon the meanings of women’s marginality and resistance. Of particular interest are the hiatuses of memory in “Sketch,” for recovering her own body and establishing a voice from within it constituted a conflicting and contradictory process, to which Virginia Woolf responded with unique narrative strategies. General and private perspectives merge, not only because of the troubles of not being personal when writing one’s own life but because Woolf claims that leaving out “the person to whom things happen” is undesirable. Even though she may meet silence when including herself personally in her writings, silence is embraced as a constituent. I suggest that much in the same way Woolf juxtaposes temporalities and subjectivities in "Sketch," personality, impersonality, and their absence (or connectedness, which is another way of seeing it) are also juxtaposed in a kind of palimpsest that does not overlook corporeality but acknowledges it as essential.
The Magnitude of Warfare Revisited – System Polarity and War Duration
Authors: Nilsson Marco
Published: June 2021

One of the intractable debates in the study of international conflict is the linkage between polarity and magnitude of interstate warfare. Speculations about the effects of the structure of the international system can be traced back to the Treaty of Westphalia. This article revisits this debate with a focus on war duration, which has received little attention in the literature, and presents the first theoretical discussion of the connection between polarity and war duration. It also uses a hazards model to statistically test whether five different measures of polarity are associated with war duration (1816-1992). The results provide initial support for the hypothesis that an increase in the number of poles in the state system is associated with longer wars on average. The empirical analysis and the theoretical discussion are important for understanding the consequences of the declining U.S. hegemony.
Suboptimal Selective Service: An Analysis of the Obstacles to Selective Service Reform in American Political Institutions
Authors: Margulies Max , Foodman Leah
Published: June 2021

Expanding mandatory selective service registration in the United States to include women would seem to be good public policy that increases national security and reduces gender bias. Despite the recent recommendation of a congressionally-mandated commission, recent efforts to implement this important reform have repeatedly stalled. Why? In this article, we explain the failure of selective service reform through the lens of American political institutions. Neither the composition of the Supreme Court, nor the institutional incentives facing legislators, are conducive to movement on this issue. Building on the legislative entrepreneurship literature, we argue that recent trends in congressional representation and the adoption of new issue framings are the most likely factors that will increase the probability of selective service reform. The absence of selective service reform in the United States reveals important facts about agenda-setting in defense policy and how political institutions shape the relationship between the public and the military.
