Abstract

Background
One of the greatest neuro-oncological concern remains the lack of knowledge about the etiopathogenesis and physiopathology of gliomas. Several studies reported a strict correlation between radiological features and biological behaviour of gliomas; in this way the velocity of diametric expansion (VDE) correlate with lower grade glioma aggressiveness. However, there are no the same strong evidences for high grade gliomas (HGG) because of the lack of several preoperative MRI.

Patients and methods
We describe a series of 4 patients affected by HGG followed from 2014 to January 2019. Two patients are male and two female; two had a pathological diagnosis of glioblastoma (GBM), one of anaplastic astrocytoma (AA) and one had a neuroradiological diagnosis of GBM. The VDE and the acceleration time (AT) was calculated for fluid attenuated inversion recovery (FLAIR) volume and for the enhancing nodule (EN). Every patients underwent sequential MRI study along a mean period of 413 days.

Results
Mean VDE evaluated on FLAIR volume was 39.91 mm/year. Mean percentage ratio between peak values and mean value of acceleration was 282.7%. Median appearance time of EN after first MRI scan was 432 days. Mean VDE was 45.02 mm/year. Mean percentage ratio between peak values and mean value of acceleration was 257.52%.

Conclusions
To our knowledge, this is the first report on VDE and acceleration growth in HGG confirming their strong aggressiveness. In a case in which we need to repeat an MRI, time between consecutive scans should be reduced to a maximum of 15–20 days and surgery should be executed as soon as possible.

Abstract

Objectives
The long-term outcomes of patients with systemic lupus erythematosus (SLE)-related protein-losing enter-opathy (PLE) are unclear. This study was aimed to investigate the clinical characteristics and long-term outcomes of patients with SLE-related PLE.

Methods
This retrospective cohort study enrolled 58 patients with SLE-related PLE who were admitted to our center from January 2000 to June 2016. The patients’ baseline characteristics and follow-up data were analyzed, and the prognostic outcomes were survival and disease flares. The prognoses were analyzed using Kaplan-Meier curves, log-rank tests, and Cox regression models. Factors with values of P<0.05 were considered potential predictors.

Results
Two-thirds of patients had intestinal symptoms, and 77.6% of patients had concomitant organ/system involvement, including serositis (77.6%), lupus nephritis (57.6%), neuropsychiatric lupus (10.3%), and hematological disorders (22.4%). Common abnormalities in the laboratory test results were hypocomplementemia (87.9%), anti-Sjögren syndrome antigen A antibodies (51.7%), and high total cholesterol levels (62.1%). Five flares were recorded in 47 patients. The 1-, 3-, and 5-year survival rates were 93.6%, 91.3%, and 88.4%, respectively. Infection was the cause of death in 60% of patients. High 24-hour urine protein level was an independent risk factor associated with death (P = 0.012). Severe hypoalbuminemia (<12 g/L) was a predictor of disease flares in SLE-related PLE (hazard ratio, 10.345; 95% confidence interval, 1.690–63.321).

Conclusions
Infection causes most of the deaths in patients with SLE-related PLE. High 24-hour urine protein level is an independent risk factor associated with death, and severe hypoalbuminemia is a predictor of disease flares.

Abstract
This work apply a deep learning artificial neural network model – the Multilayer Perceptron – as a regression model to estimate the demand of bus passengers. Transit bus ridership and weather conditions were collected over a year from a medium-size European metropolitan area and linked under the assumption: individuals choose the travel mode based on the weather conditions that are observed during (a) the departure hour, (b) the hour before or (c) two hours prior to the travel start. The transit ridership data were also labelled according to the hour of the day, day of the week, month, and whether there was a strike and/or holiday or not. The results show that the prediction error of the model decrease by ~9% when the weather conditions observed two hours before travel start is taken into account. The model sensitivity analyses reveals that the worst performance is obtained for a strike day of a weekday in spring (typically Wednesdays or Thursdays).

Published: December 2020

Este estudo se ocupa da aquisição das regras de conversação pela criança em sua vivência interacional com os demais sujeitos. Concebe-se a aquisição das regras da conversação pela criança a partir de valores simbólicos que afetam o modo como ela se relaciona com a língua e com o outro. A língua é concebida como prática social, sendo que as condições de produção se relacionam com as questões linguísticas. São questões desta investigação: Como a criança, desde muito cedo (3 anos e 5 meses), estabelece uma dinâmica interacional com os demais sujeitos de seu convívio? Qual o papel do outro nessa relação? Como se dá a apropriação dos elementos linguísticos nessa dinâmica? Para buscar respostas a essas questões, ilustra-se a pesquisa com a análise de um dado de uma criança de 3 anos e 5 meses, dado que faz parte do Banco do grupo NALíngua. A análise indica que a criança ativa conhecimentos anteriormente partilhados, em outras interações, para ocupar seu espaço de dizer nas novas situações conversacionais. Assim, os elementos linguísticos são atualizados a cada nova interação, na vivência, por parte da criança, de um trabalho colaborativo de construção da conversação, evidenciado nas negociações no estabelecimento do sentido.

The present research work was aimed to design, develop and evaluate the nano lipid-based drug delivery system by incorporating timolol hydrochloride drug for ocular therapy and improve the release of the drug through the ocular route. Nanolipids in situ gels were prepared by film hydration method involving two steps. First nano lipids were formulated with the help of organic solvents, and then they were incorporated into a gel by using gelling agents. FTIR spectrum studies were carried out for drug and the formulations which reveal that there was no interaction between the drug and excipients used. The various formulations prepared were subjected for the different evaluation parameters, which showed good and effective results for visual appearance, pH, gelation study, viscosity and ocular irritation studies. It was further observed from this research work that formulation TF2 (HPMC K-15M 0.2%w/v and Carbopol 940 0.4%w/v) had a maximum entrapment efficiency of 97.30%, drug content of about 97.67% and drug release of about 84.29% for 10 hrs. Stability studies were carried out for TF2 formulation, and they found that they were stable throughout the study period. It was finally concluded from the present work that formulations prepared were more suitable and had good patient compliance compared to the eye drops.

Paradise Lost: Explaining Populism as a Response to the Fragmentary Nature of Time, Space, and the Rapid Pace of Technological Advancement
Authors: Vrhoci Dora 
Published: December 2020

Contemporary societies and technologies are evolving at an ever-swifter pace. Advances in the field of Augmented Reality (AR) and in Computer Science at large have led to games that let us immerse ourselves in worlds stuffed with zombies, robots, or pokemon critters. Globalization is making the world ever more interconnected, and the development of diverse social media platforms is changing the way people engage with politics and culture in their daily lives. Time and space have arguably never been more liquid, fragmentary, and compressed. Against this host of developments, Postmodern ideas on the fragmentation of time and space,the rupture in personal and national identity narratives, as well as the concept of «utopia,» can provide theoretical tools, shedding light on how various agents react to the rapid pace of technological change (such as Information and Communications Technology (ICT) and digitalization), and subsequent alterations in Man’s perception of time and space. This paper reconstructs the key tenets of Postmodern thinking on cultural phenomena, showing how the changing experience of time and space (induced by globalization, and technological advances) bear on the recent successes of populist parties in Europe and beyond. Furthermore, the paper places populists’ narrative of and nostalgic mourning for an ideal past in a longer continuum of utopian and dystopian thinking. This is then interpreted as an attempt to build a vision of a homeostatic space that, once conceptualized as a rhetorical tool, serves to forgebonds among ‘(good) people
Valencia’s ‘Men for Equality’ movement. An assessment of some of its protagonists
Authors: Rodríguez del Pino Juan Antonio , Aguado i Hernàndez Juli Antoni 
Published: December 2020

The Men for Equality movement [El movimiento de hombres por la igualdad - HPLI], although a fairly recent phenomenon, already has a forty year track record in Valencia. The movement has had its high and low points. After the trail blazed by protagonists in Valencian society, a period of consolidation followed in which those who came after them kept the movement going. A qualitative study carried out by the Department of Sociology and Social Anthropology records the impressions of those men who kept the movement alive between 1975 and 2018 despite the odds at the outset. These voices are analysed within frameworks for interpreting movements. As a social movement, Men for Equality developed new codes of behaviour and meaning. The resultsreveal the need – now greater than ever – of a paradigm shift in masculinity in Spain and Valencia.

Authors: Scribano Adrián , Jingting Zhang 
Published: December 2020

Internet celebrities, as a group of stars spawned by the market economy and The Internet, reveal both the state of Internet culture and the transformation of mass media in China. The bodies and pictures of these ‘celebs’, while unique, also take on a cultural symbolism. The 4.0 Revolution is the carrier of social practices and kinds of interaction in which the social media play a very special role. In this paper we will focus on the intersections and ruptures between the bodyindividual, body-subjective and body-social (Scribano, 2007) of Chinese Internet celebrities and the articulations and links between body-image and their body-in-movement. With the introduction ofChinese social media platforms such as WeChat (微信), Sina Weibo (新浪微博), Douyin, we try to trace links between the sociability, experiences and social sensibilities of the Internet celebrities and their influence on Society 4.0. This paper: (a) looks at the Chinese social media as a virtual platform for the Internet celebrities; (b) delves into the images and practices of the Internet celebrities; (c) highlights the link between body, sensation and perception regarding social celebrities; (d) shows the kinds of sociability and social sensibilities exhibited by celebrities in China’s Society 4.0. home foreclosure) in several Catalan municipalities.

Woman, manage your life! The Life-Work Balance Discourse in Popular Management Literature Aimed at Women*
Authors: Medina-Vicent Maria 
Published: December 2020

Management posts have traditionally been held by men. Consequently, the business management normative model has dictated the rules women should follow. Among other reasons, this is why the issue of work-life balance has been sidelined in popular management literature. In keeping with these male-dictated rules, it was always blithely assumed that the manager's role was exclusively linked with his public presence — in other words, family and care issues were left out of the equation. However, as more and more women have become managers, new issues have shaped the management agenda. In this paper, we study how the issue of work-life balance has been incorporated in popular management literature for women. We are particularly interested in identifying whether the discourse on women’s presence in management enshrines: (1) a transformative, egalitarian vision (requiring policies fostering work-life balance), or (2) a view that sees women’s traditional household roles as something belonging to the private sphere, leaving them disadvantagedand bereft of support as they pursue their management careers.
Cos/emocions de les celebritats d'internet en la societat 4.0 a la Xina
Authors: Scribano Adrián , Jingting Zhang 
Published: December 2020

Les celebritats d'internet, com a grup d'estreles produïdes per l'economia de mercat i internet, mostren la transformació i la situació actual de la cultura d'internet i les xarxes socials a la xina. En el físic i la imatge que projecten aquestes celebritats, si bé són úniques, hi ha implícit un simbolisme cultural. La revolució 4.0 ens porta noves pràctiques socials i maneres d'interactuar amb les xarxes socials com a protagonistes. En aquest article investigarem les interseccions i ruptures entre cos-individu, cossubjectiu i cos-social (Scribano, 2007) de les estreles d’internet xineses, i les articulacions i relacions entre el cos-imatge i el seu cos-en-moviment. Analitzem plataformes de xarxes socials xineses com WeChat (微信), Sina Weibo (新浪微博) o Douyin per rastrejar vincles entre la sociabilitat, les experiències i les sensibilitats socials de les celebritats d'internet i la seua influènciaen la societat 4.0 xinesa.Aquest article (a) examina les xarxes socials xineses com a plataforma virtual de les estreles d’internet; (b) aprofundeix en les imatges i pràctiques de les estreles d’internet; (c) subratlla la relació entre el cos, la sensació i la percepció quant a lescelebritats socials; (d) mostra els tipus de sociabilitat i sensibilitats socials exhibides per les celebritats en la societat 4.0.
La cultura en nom del poble? Cap a una tipologia del populisme i la cultura
Authors: Jansma Judith 
Published: December 2020

Durant les últimes dècades, el populisme ha estat àmpliament estudiat, tot i que des d’una perspectiva majoritàriament política. Les contribucions en aquest camp se centren sobretot en l’anàlisi del populisme com a fenomen sociopolític en el context històric i global. Una altra àrea d’estudi es refereix al suport popular dels partits populistes. Aquesta qüestió, a més de ser de la màxima actualitat, revela les imperfeccions de la democràcia liberal.Tot i que s’ha dedicat un gran esforç acadèmic a proporcionar una definició de populisme i les raons de l’èxit que té, encara queda per aclarir en quines creences culturals es basen els seus arguments populistes que empren una falsadicotomia entre «nosaltres» i «ells». Per aquesta raó, després de fer un breu resum del treball acadèmic que s’ha fet fins avui en les disciplines de la ciència política i els estudis culturals, intentarem presentar una tipologia de la culturai el populisme, que ens ajudarà a entendre per què els diferents aspectes de la cultura (com ara la cultura popular, les imatges culturals i les obres literàries) són de capital importància en la construcció populista del «nosaltres» i l'«ells».La tipologia es basa en els exemples de França i Holanda (dos països amb importants partits de dreta populista) per a distingir entre sociofacts, mentifacts i artifacts (Huxley) i l’ús que tenen en l’apropiació dels actors populistes. L’última categoria es compon d’allò que anomenarem «autors orgànics» i «autors apropiats», en la terminologia emprada per Gramsci. La diferència entre les dues, com es demostrarà, rau en la identificació de l’autor amb un tipus determinatd’idees, així com en l’articulació d’aquestes.
Non-Hermitian Hamiltonian Treatment of Stark Effect in Quantum Mechanics
Authors: Hallford Randal , Sharma Preet 
Published: December 2020

The Non-Hermitian aspect of Quantum Mechanics has been of great interest recently. There have been numerous studies on non-Hermitian Hamiltonians written for natural processes. Some studies have even expressed the hydrogen atom in a non-Hermitian basis. In this paper the principles of non-Hermitian quantum mechanics is applied to both the time independent perturbation theory and to the time dependant theory to calculate the Stark effect. The principles of spherical harmonics has also been used to describe the development in the non-Hermitian case. Finally, the non-Hermitian aspect has been introduced to the well known Stark effect in quantum mechanics to find a condition in which the Stark effect will still be true even if a non-Hermitian Hamiltonian is used. This study completes the understanding at a fundamental level to understand the well known Stark effect. Doi: 10.28991/esj-2020-01242 Full Text: PDF
Current and Historical Application of Knowledge Management in Economy
Authors: Tomé Eduardo 
Published: December 2020

Objectives: The paper tries to analyse the current and historical application of Knowledge Management in the Portuguese Economy, particularly since the democratic revolution of 1974. Methods/Analysis: Study is based in theories about the impacts of knowledge in countries at a micro and a macro scale. A three levels mode is used, related to context (namely 1) Historical background; 2) basic economic and social data: 3) broad vocational education and training (VET) systems; 4) institutional actors; 5) political context), intervention (namely 1) basic legislative documents, 2) guidelines on eligibility, 3) programs, 4) evaluation procedures) and outcomes (namely 1) stocks, investment, and outcomes; 2) price, quantity, supply, demand, equilibria; 3) needs). Data used are statistical published data and other published documents. Findings: The context changed for the better, because after 1974 the country rulers installed a regime in which knowledge was not seen like a luxury but as a basic need; the change in context was also helped by the adhesion to the EU, which in turn led to massive interventions supported by funds like the ESF and the Regional fund; as a result outcomes are finally seen, as the increase in supply and demand of knowledge and also in the income and employability of the Portuguese attests. Novelty/Improvement These findings are important because they depict the slow but sure transformation of Portugal into a Knowledge Economy. Should be complemented by a more detailed analysis, with a larger group of researchers. Doi: 10.28991/esj-2020-01245 Full Text: PDF
Analysis of Host Resources Utilization by OpenStack in Ubuntu Environment
Authors: Pericherla Suryateja Satya 
Published: December 2020

Cloud computing is one of the frontier technologies, which over the last decade has gained a widespread commercial and educational user base. OpenStack is one of the popular open source cloud management platforms for establishing a private or public Infrastructure-as-a-Service (IAAS) cloud. Although OpenStack started with very few core modules, it now houses nearly 38 modules and is quite complex. Such a complex software bundle is bound to have an impact on the underlying hardware utilization of the host system. The objective is to monitor the usage of system resources by OpenStack on commodity hardware. This paper analyzes the effect of OpenStack on the host machine's hardware. An extensive empirical evaluation has been done on different types of hardware, at different virtualization levels and with different flavours of operating systems comparing the CPU utilization, memory consumption, disk I/O, network, and I/O requests. OpenStack was deployed using Devstack on a single node. The novel aspect of this work is monitoring the resource usage by OpenStack without creating virtual machines on commodity hardware. From the analysis of data, it is observed that standalone machine with Ubuntu server operating system is the least effected by OpenStack and thereby has more available resources for computation of user workloads.
