Possibilidades e limites na criação coletiva de artigos da Wikipédia: o artigo “Vitor Marinho de Oliveira”
Authors: Ramyssés Vieira Dias Leon , Malina André , Telles Silvio , Miarka Bianca , Celeste Barreto de Azevedo Ângela 
Published: May 2021

No presente estudo, discutiu-se, a partir da análise da criação do artigo “Vitor Marinho de Oliveira”, – um intelectual vinculado à área sociocultural da Educação Física – o fenômeno da Wikipédia, uma enciclopédia organizada em hipertexto e de colaboração cooperativa. Para tal discussão, descreveu-se o processo de criação e submissão do artigo na Wikipédia, apontando os limites e as possibilidades, bem como a interação com a própria plataforma. Utilizou-se como referencial teórico as concepções de Álvaro Vieira Pinto sobre a tecnologia, além de autores que trataram especificamente da Wikipédia. Como principais resultados, foram encontradas limitações para publicação de artigos na Wikipédia, embora os critérios de criação coletiva do conhecimento, tratando-o como um bem público e com difusão gratuita, atenda a uma perspectiva crítica da tecnologia. Para além disso, recomenda-se aos pesquisadores da Educação Física a massificação de publicações no ciberespaço visando preencher essa lacuna e dar usufruto aos leitores da Wikipédia sobre questões relevantes da área, incluindo o conhecimento dos seus principais intelectuais.
The Deterrent Effect of Insider Trading Enforcement Actions
Authors: Davidson Robert H. , Pirinsky Christo 
Published: May 2021

ABSTRACT
We analyze whether exposure to an SEC insider trading enforcement action affects how insiders trade. We find that following an insider trading enforcement action at one firm, exposed insiders earn significantly lower abnormal profits from their trades at other firms compared to non-exposed insiders. The deterrent effect is stronger when a fellow insider is convicted, and is similarly significant both pre- and post-SOX. Following the enforcement event, exposed insiders do not trade less frequently, but do trade significantly fewer shares per trade. Insiders who have witnessed an enforcement action have a lower probability for future conviction than their unexposed peers.

Interest Rate Modelling in the Presence of Discontinuities and its Sensitivities
Authors: Udoye Adaobi M. , Ogbaji Eka O. , Akinola Lukman S. , Annorzie Maurice N. 
Published: May 2021

Abstract
Interest rate paths experience discontinuities in the presence of certain factors. Much of the work on interest rate modelling has no consideration for effects of such unexpected occurrences in real life. A good risk manager needs to have a better model that considers possibility of unexpected occurrences. In this paper, we discuss step by step extension of Vasicek model to both jump model and jumpdiffusion model using Itô’s formula as the major tool. We also derive the greeks ‘delta’ and ‘vega’ that measure sensitivity of the interest rate with respect to both changes in its initial interest rate and volatility in an interbank rate.
Gender and Ethnicity: Life Stories of Jewish-American Immigrant Women in the First Half of the Twentieth Century
Authors: Iancu Anca-Luminiţa 
Published: May 2021

Abstract
In the first half of the twentieth century, immigrants left oral and written testimonies of their experience in the United States, many of them housed in various ethnic-American archives or published by ethnic historical societies. In 1942, the Yiddish Scientific Institute in New York City encouraged Jewish-American immigrants to share their life stories as part of a written essay contest. In 2006, several of these autobiographical accounts were translated and published by Jocelyn Cohen and Daniel Soyer in a volume entitled My Future Is in America. Thus, this essay examines the autobiographies of two Jewish-American immigrant women, Minnie Goldstein and Rose Schoenfeld, with a view to comparing how their gendered identity (as women and as members of their families) has impacted their choices and lives in their home countries and in the United States in the first part of the twentieth century.
Inherited or Acquired in Hipertension and Cronic Kidney Disease in Diabetes Mellitus Patients?
Authors: Stoian Marilena , Dumitrache Ana Maria , Cîrciu Fivi , Stoica Victor , Radulian Gabriela 
Published: May 2021

Abstract
Diabetic kidney disease (DKD) is a common and serious microvascular complication of diabetes mellitus (DM), which is characterized by an elevated urinary albumin excretion rate, elevated blood pressure, and declined renal function. Approximately 30-40% of DM patients will develop DKD, which is the leading cause of end-stage renal disease (ESRD) and renal failure. Genetic factors appear critical in DKD pathogenesis based upon the evidence including aggregation in families, variable incidence rates of DKD between different races, and the highly heritable nature of diabetic renal clinic and histologic changes.
Each 10 mmHg increase in mean systolic blood pressure (BP) was associated with a 15% increase in the hazard ratio for development of both micro- and macroalbuminuria and impaired kidney function defined as eGFR <60 ml/min per 1.73 m2 or doubling of the blood creatinine level. Broadly, a baseline systolic BP >140 mmHg in patients with DM2 has been associated with higher risk of ESRD and death.
The ACE genes may predict diabetic nephropathy in some groups, the rate of progression and the antiproteinuric response to ACE inhibitors.

Authors: Milović Nikola , Jocović Mijat , Martinović Nikola 
Published: May 2021

Abstract
Competitiveness, as a complex concept, can be observed in different ways, from the perspective of an individual, group, company and/or state. The subject of this paper deals with competitiveness of national economies observed through factor analysis, with a particular focus on the level of macroeconomic stability. Through the application of the Analytical-Hierarchical Process (AHP) method, special attention has been paid to the comparative ranking of Western Balkan countries. The ranking has been made in relation to macroeconomic stability and the positions of countries in the ranking of the World Economic Forum, based on the Global Competitiveness Index, for three defined periods of time. The paper identifies key factors that affect the competitiveness of Western Balkan countries. Research findings show that macroeconomic stability has a strong impact on the level of global competitiveness of national economies.
Does market competition affect all banks equally? Empirical evidence on Montenegro
Authors: Vujanović Nina , Fabris Nikola 
Published: May 2021

Abstract
Bank stability is an important aspect of financial stability, especially in bank-centric systems like that of Montenegro. Hence, it is important to analyse risks affecting stability of both the banking and financial system as a whole. Rising competition among banks could pose a challenge and possibly change the level of credit risk, especially if the banks are small in size. This can affect both credit risk and financial stability. Small-sized banks could be the ones to react less nimbly to a changing market structure than bigger banks with stable market shares. This study tries to answer whether competition affects credit risk in Montenegro and whether banks differing in size react differently. Panel data techniques were applied to eleven banks which account for over 90 percent of the banking sector. The results indicate that market concentration could be particularly harmful when it comes to credit risk of small-sized banks, while large-sized banks are less affected. Overall, the increasing competition may positively affect credit risk in Montenegro.

Published: May 2021

Abstract
This study examined the nexus between monetary policy and the achievement of a bank’s profit objective. There have been lots of arguments about the benefits of monetary policy implementation on deposit money bank’s operations, since the policies have been seen to impact on their performance. This study was carried out to establish the influence of variables like Liquidity Ratio, Interest and Money supply (M2), which are used as monetary policy instruments, on deposit money bank profitability objective. The study covers the period from 2002-2019. The Auto Regressive Distributed Lag and Error correction model were adopted in the analysis of the data. The study revealed that there was a positive long run relationship between Liquidity Ratio and deposit money bank’s profitability; there also existed a negative long run relationship between interest rate and deposit money bank profitability; lastly, there existed a positive long run relationship between Money Supply (M2) and deposit money bank’s profitability. Based on the findings, monetary authorities should put in place measures for Liquidity ratio, interest rates and M2 implementation to aid deposit money banks operations in the achievement of their profit objective.
A study of securing in-vehicle communication using IPSEC protocol
Authors: Lastinec Jan , Hudec Ladislav 
Published: May 2021

Abstract
Current vehicles are increasingly dependent on Electronic Control Units (ECUs) that control virtually every system of the vehicle. To enable advanced features automotive embedded systems are opening to external world, which raises security concerns. At the same time these innovative systems require more complex software and higher bandwidth for information exchange. Thanks to its bandwidth, payload size, and openness, Ethernet is a candidate technology for future in-vehicle architectures. This paper deals with design of a novel approach to secure In-vehicle Systems by taking advantage of Ethernet/IP technology and proven security mechanisms from TCP/IP model. Main goal is to design an efficient solution that meets requirements for latency without requiring high amounts of processing power and provides secure exchange of control messages. The work is mainly focused on the widespread Controller Area Network (CAN). The presented solution is based on encapsulation of CAN frames into UDP datagrams with added authenticity, integrity, and (if required) confidentiality of communication using IPsec protocol in transport mode. This creates a “secure tunnel across backbone Ethernet network in a vehicle. Next part of the paper presents extensive tests in simulation that are based on our previous experiments on hardware, in order to evaluate the characteristics of the designed security extension. The results indicate that using IPsec is a viable solution for securing in-vehicle communications.
Shape retrieval using angle-wise contour variance
Authors: Yildirim Mustafa Eren , Ince Omer Faruk , Salman Yucel Batu , Ince Ibrahim Furkan 
Published: May 2021

Abstract
In this study, we propose a geometric feature set for 2D shape retrieval. Conventional Hough feature gives the edge locations along with angle and creates Hough table if there are multiple intersections at borders. In this paper, a statistical way to represent the relation of repeating contours at each angle around the shape centroid is presented. The main contribution of this paper is to use the standard deviation of repeating contours. We calculate the angle between the shape centroid and each point on the contour. For each integer angle value, three features were extracted: the number of contour repetitions, the average distance of the points at that angle to the centroid, and the standard deviation of the points at the same angle. Thus, a 2D image was represented by a constant sized matrix, regardless of its size. In the case of similarity between two images, instead of merging features within a single expression, the algorithm picked the feature with the highest similarity rate for that comparison. We tested the proposed method on MPEG-7, Kimia99, ETH-80 datasets for a benchmark with the state-of-the-art. It outperformed most of the recent methods in terms of retrieval rate.
Design and verification of a low-power AC/DC converter
Authors: Potočný Miroslav , Stopjaková Viera , Kováč Martin 
Published: May 2021

Abstract
This paper deals with the development and experimental verification of a low-power AC/DC converter. The proposed solution is aimed at the sub 0.5 W output power domain, commonly encountered in applications such as always-on wireless sensing nodes. To implement the proposed converter topology, a prototype application specific integrated circuit was designed and manufactured in a high voltage 0.35 µm CMOS technology, able to handle the maximum voltage of up to 120 V. The proposed design was first analyzed by transistor-level simulations showing high power efficiency and low no-load consumption of the developed converter. To facilitate experimental verification and measurement, an printed circuit board with the necessary external components was developed, as the available technology is unable to handle the AC line voltage directly. While the developed converter operated well with decreased input AC voltage, reliability issues arose during operation with the full AC line voltage of 230 Vrms. These are linked to digital control circuitry of the implemented chip and could be addressed in the second manufacturing run in the future.
Estimation of the surface user distribution influence on the interference from adjacent cells in CDMA network
Authors: Mitić Dragan , Lebl Aleksandar , Markov Žarko 
Published: May 2021

Abstract
In this paper we consider the network of mobile users where CDMA technique is used in cells. The dependence of disturbances/interference in the uplink direction as a result of surface user distribution in the neighbouring cells is determined. Three user distribution types are considered: the uniform one, decreasing from the cell centre to the rim and the increasing one. The interference calculation is performed using mean values of user distance from the cell centre. It is proved in the paper that interference caused by decreasingly and increasingly distributed users may differ from the interference caused by the cell with uniform user distribution by not more than ±75%.
Role of earth-abundant selenium in different types of solar cells
Authors: Dey Tania 
Published: May 2021

Abstract
This mini review covers a brief overview of three generations of solar cells, definition of major photovoltaic (PV) parameters, mechanisms, advantages and limitations of different types of solar cells such as multijunction, thin film, quantum dot, dye sensitized and perovskite solar cells, and what role the earth abundant selenium can play in each type of solar cells, followed by a comparative study of the benefits and challenges that selenium can offer in terms of PV properties, as well as the major players and cost analysis in this arena. As far as PV properties are concerned, BaZr(S0.6Se0.4)3 distorted chalcogenide perovskite solar cell can possibly lead the future, the next best ones being AlGaInP multijunction solar cell with Se emitter dopant and Se electrolyte additive in Zn-Cu-In-Se QD-sensitized solar cell. Cost-wise perovskite cell holds a lot of promise, but the efficacy of selenium needs to be explored further.
Puppets – In Times Of Peace And War
Authors: Ciobotaru Anca Doina 
Published: May 2021

Abstract
Usually, social crises are associated to socio-political systems, regardless of their intensity. This premise might lead to the following question: what is it that can cause a connection between puppets and such a context? This question was raised by a series of researchers and it determined them to search, find out and interpret.
Even a mere scan through the history of animation theatre1 leads to the observation that situations of crisis generate reactions/answers, in terms of performance, that can be subject to: the wish to convey a message (that has the power to influence), an artistic movement – structured as a form of answer, a current of thought – with or without political influences. Boundaries between these are purely theoretical, as the interferences are an indisputable reality. I shall only bring forth several examples, which I consider significant for the three dimensions of the proposed hypothesis that are to be analysed, as it is clear that an exhaustive list of examples would be an almost impossible task; the ephemerality of theatre makes its history hard to trace. Beyond dates, technical systems, puppeteers’ titles and names, whose journeys stand under the sign of relativity, there is a constant: the puppeteers’ presence changes perspectives. It is this aspect which I want to draw attention to, marking the possible development of a future, more ample research.

Lyric Theatre – between #rezist and #exist
Authors: Bogdan Stanca Maria 
Published: May 2021

Abstract
In general, the arts and, in particular, the performing arts are proving to be both affected and sensitive, reactive to societal convulsions, regardless of their nature. Performance institutions are dependent not only on the audience they have created, but, above all, on the funding through which they can shape and convey their artistic message. Overall, crisis situations are associated with a negative context, expressing a stage marked by great difficulties (financial, economic, political) that impact all areas with a domino effect. In such situations, cultural institutions, particularly those in the performances arts0 and especially lyric theaters become one of the predilect victims to suffer from the rationalization of resources, being considered inessential, the perfect sacrificial pawn. But, at the pinnacle of a crisis, cultural performances, drawing from the creator-artist relation, commit to become a coagulating, driving, regenerating social factor, like a Phoenix rising from its ashes. A great such example is Ciprian Porumbescu’s operetta, „Crai Nou”, which held great significance for the Romanian identity when it was first released to the public.
Performing Arts and Society’s Major Crisis
Authors: Vladu Bogdan Petre 
Published: May 2021

Abstract
Moments of major crisis in a society subdued by economic and identity interests. Shutting down the performing arts with the intention of subjugating the community by eliminating forms of psychological resilience in moments of crisis? Is the medical crisis an engine of economic capture at the expense of maintaining the mental health of the population? Does political correctness have the power to change perceptions of immediate reality? Can we look back to the immediate past in an attempt to untie the Gordian knot that suffocates theatre in this period of inquisitorial valence in an attempt to save the aesthetic approach?

Se determinó la influencia del peso, temperatura y tiempo de inyección de vapor saturado en el Sistema de Esterilización Orgánica (OSS por sus siglas en inglés) sobre la carga microbiana, análisis proximal y contenido de capsaicina en el ají mirasol y el ají panca. Se trabajó con 3 y 4 kg de ají, 100 y 105 °C (20 y 25 kPa), por 2 y 3 min. Los análisis pre y pos-OSS fueron los siguientes: recuento de aerobios mesófilos viables, coliformes totales, E. Coli, Salmonella, mohos y levaduras, proximal y contenido de capsaicina. Las muestras de 3 kg del ají mirasol, sometidas a 105 °C por 3 min, y las de 3 y 4 kg del ají panca, sometidas a 105 °C por 3 min, lograron mayor reducción de aerobios mesófilos y mohos. En la evaluación estadística se encontraron interacciones entre las variables peso y temperatura en ají mirasol; entre peso, temperatura y tiempo en el ají panca, sobre la reducción de aerobios mesófilos y mohos; esto influye en la composición proximal y reducción del contenido de capsaicina de 863.2 a 751.9 ppm (ají mirasol) y 405.6 a 315.1 ppm (ají panca); evidenciando que el tratamiento OSS es un método eficiente en procesos de descontaminación microbiana.

Deklarowany etos nauki polskich uczelni
Authors: Czakon Tomasz 
Published: May 2021

Zmieniają się zasady funkcjonowania nauki, zmieniają się wyobrażenia o jej etycznie akceptowanym modelu. Badacze zajmujący się tymi przemianami twierdzą, że następuje odejście od etosu nauki akademickiej do etosu nauki przemysłowej, „korporacyjnej”. W uchwalonej w 2018 roku przez Sejm Rzeczypospolitej Polskiej nowej ustawie o szkolnictwie wyższym i nauce znacząco inaczej uregulowano funkcjonowanie szkół wyższych. Podstawowym celem artykułu było zbadanie etosu naukowego w Polsce, badania zostały oparte na tekstach nowych statutów przyjętych przez senaty polskich uczelni. W tych dokumentach wyszukano wartości i deklaracje, które wyrażają przekonania władz uczelni o tym, jaki model nauki jest najważniejszy. W badaniach porównaniu poddano dwie grupy uczelni: uczelnie, które uzyskały status uczelni badawczych, oraz uczelnie z Górnośląsko-Zagłębiowskiej Metropolii. Próbowano uzyskać odpowiedzi na pytania: 1) Jakie wartości tworzą deklarowany etos nauki?; 2) Jaka jest ich hierarchia?; 3) W jakim zakresie etosy nauki w obu grupach uczelni są podobne?; 4) Czy etosy nauki zapisane w nowych statutach różnią się od tych, które uczelnie deklarowały wcześniej? W badaniu zastosowano analizę treści dokumentów. Jak pokazują wyniki badań, etos nauki ulega zmianie, a zestaw deklarowanych w analizowanym materiale wartości jest bogaty i zróżnicowany.
