Some Kinds of Sparseness on the Real Line and Ideals on ω
Authors: Filipczak Małgorzata , Horbaczewska Grażyna
Published: July 2020

We show that a large class of summable ideals can be defined using a certain kind of “sparseness” of subsets of the line near zero, but it is still an open question whether this gives a characterization of the whole class.

Image Analysis as a Method of the Assessment of Yarn for Making Flat Textile Fabrics
Authors: Idzik Marcin , Idzik Marek
Published: July 2020

During the technological processing of staple fibers into yarn drafting, waves are formed which increase the irregularity of yarn linear density and consequently affect the yarn quality. Even a correctly performed technological process does not allow one to completely eliminate yarn faults (thin and thick places, neps) and yarn irregularity. All the yarn imperfections distinctly become apparent in flat textiles made of such a yarn. The quality of the yarn produced should be assessed already in spinning mill, using the results obtained to conclude on the quality of woven or knitted fabrics. Modern metrological laboratories in spinning mills possess Uster Tester 5 (UT5) apparatuses that not only assess the yarn quality with respect to the irregularity of linear density, faults (thin and thick places, neps), or hairiness, but also using the test results obtained make it possible to create a digital image of the predicted appearance of a flat fabric made of the yarn tested. This article presents a computer-aided method of the analysis of the woven and knitted fabric images obtained from UT5 that allows one to assess the significance of particular yarn parameters in the predicted appearance of flat fabrics.
The Impact and Importance of Fabric Image Preprocessing for the New Method of Individual Inter-Thread Pores Detection
Authors: Owczarek Magdalena
Published: July 2020

The paper describes the impact and importance of preprocessing methods of fabric image for detection of inter-thread pores (ITP), which is a new method of individual ITP identification. The aim of this experiment is to identify precisely every individual ITP of fabric structure by using optimal preprocessing algorithm for further quantitative, morphometric structural analysis of specialized fabrics (barriers, industrial filters, composites, others) in context of air permeability, flow resistance, UV radiation, viruses penetration, thermal comfort by estimation fabric porosity, especially macroporosity parameters and cover factor. The correct identification of individual ITP depends on the acquisition method and the preprocessing algorithm. It was conducted by analyzing the adaptation of digital image preprocessing methods for two structures of plain weave fabric in two magnification zooms, 1.25 and 0.8. Preprocessing operations were performed in the area of spatial operations of the image. The optimal preprocessing algorithm includes low-pass filtering, histogram equalization, nonlinear filtering, thresholding, and morphological operation. This algorithm was selected based on the factors developed by the author (ITP detection, RID factor—a difference between the real and model ITP areas) which rely on the ITP size, shape, and location. The graphic view of the ITP contour position on the fabric image is a verification element in the optimal preprocessing algorithm. The presented results of the air permeability of two different plain weave structures confirm the need to optimize the algorithm of pre-image processing methods to precisely detect each individual ITP in the fabric image.
Electro-Magnetic Behavior of Highly Correlated Fluorides KFeF3, KCoF3and KNiF3: A ComparativeAb-initioStudy of Cation Effect
Authors: Filalli Sihem , Hamdad Noura
Published: July 2020

Fluorides-based perovskites are currently the typical materials being used in spintronic devices, optoelectronic and magneto-resistance colossal fields. Solar cells made of Fluoro-perovskite hold much promise for the future of solar energy. The electronic structure and magnetic properties of KFeF3, KCoF3and KNiF3Fluorides are studied using ab initio Calculation. We have analysed the structural phases, total and partial electronic densities and band structures within the (DFT) vs the DFT+U description. We show the Electro-Magnetic Behavior using L(S)DA+U vs L(S)DA in a comparative study of cation effect by integrating three types of crystal structures (Cubic (Pm-3m), Four-Layered Hexagonal (P6/mmc), and Orthorhombic (Pnma)). Equilibrium lattices agree very well with experimental and theoretical data. Magnetic moment of each phase is discussed. The obtained results confirmed that the three crystal structures invested here exhibit Ferromagnetic (FM) behavior. The introduction of the Hubbard’s parameter U increases lattice parameters and magnetic moment. We deduce that the second cation plays an important role in the magnetic effects. L(S)DA+U show correctly that KFeF3, KCoF3and KNiF3are insulators.
Persuasive or Pipe Dream? The Potential Influence of the Feminist Judgments Project on Future Judical Decision Making
Authors: Webber Nuñez Kate
Published: July 2020

The Feminist Judgments Project (“FJP” or the “Project”) rewrites existing judicial opinions from a feminist perspective. This article explores whether and how the FJP's alternative jurisprudence can influence future legal decisions. The FJP seeks to change the law by revealing unconscious bias and opening judicial minds to previously unknown perspectives - a method that draws on psychological theories of decision making such as cultural cognition. This article takes a different approach and evaluates the FJP using theories from political science. In light of the increasingly conservative judiciary and the Republican administration, the attitudinal and strategic theories of decision making would give the FJP little prospect of actually influencing the law. Thus, this article focuses on historical institutionalism to present a theoretical explanation for why and how the FJP's re-envisioned law could possibly persuade the judiciary. Specifically, the article examines the degree to which the FJP draws on social facts highlighted by the #MeToo and LGBTQ rights movements and whether the Project thereby creates the conditions for social construction and resultant legal change. It also uses theories on displacement to present a critique of the FJP's more radical re-writes and points to the more moderate approach of ideational salience amplification as effective. Ultimately, it concludes that the FJP's path of persuasion is somewhat narrow and limited, but possible.
Modelling and forecasting GDP using factor model: An empirical study from Bosnia and Herzegovina
Authors: Abdić Ademir , Resić Emina , Abdić Adem
Published: July 2020

In the most developed countries the first estimations of Gross Domestic Product (GDP) are available 30 days after the end of the reference quarter. In this paper, possibilities of creating an econometric model for making short-term forecasts of GDP in B&H have been explored. The database consists of more than 100 daily, monthly and quarterly time series for the period 2006q1-2016q4. The aim of this study was to estimate and validate different factor models. Due to the length limit of the series, the factor analysis included 12 time series which had a correlation coefficient with a quarterly GDP at the absolute value greater than 0.8. The principal component analysis (PCA) and the orthogonal varimax rotation of the initial solution were applied. Three principal components are extracted from the set of the series, thus together accounting for 73.34% of the total variability of the given set of series. The final choice of the model for forecasting quarterly B&H GDP was selected based on a comparative analysis of the predictive efficiency of the analysed models for the in-sample period and for the out-of-sample period. The unbiasedness and efficiency of individual forecasts were tested using the Mincer-Zarnowitz regression, while a comparison of the accuracy of forecast of two models was tested by the Diebold-Mariano test. We have examined the justification of a combination of two forecasts using the Granger-Ramanathan regression. A factor model involving three factors has shown to be the most efficient factor model for forecasting quarterly B&H GDP.

Published: July 2020

The subject of this research are the demographic trends and the educational system of the Republic of Srpska. The aim of the research is to define the concepts required to comprehend the demographic trends and to explore their implications for the educational system of the Republic of Srpska. In order to establish sustainable development in the Republic of Srpska, education being a key component therein, it is necessary to perceive its demographic resources in order to create an educational system. By means of empirical research with a presentation of results through factor and cluster analysis, generated quantitative and qualitative indices of demographic resources, particularly in the educational system. The Republic of Srpska as a whole belongs to type D, featuring poor demographic resources and characteristics, as well as prominent demographic disparities regarding spatial development. However, in order to increase the coverage, relevance and efficiency of completion of the education process, it is necessary to determine the strategic commitments to be accomplished together with certain quantitative demographic indicators of the achievement level (educational coverage of different generations). Demographic changes will pose a major challenge for policy makers and to the society in general across the upcoming decades and will require shaping new economic, tax, health, pension, educational, social, family and other policies that affect demographic changes. The research endeavour in this paper focuses on that very aspect, together with the respective applicative capabilities.
Roles of Patents in Economic Development and Integration
Authors: Tanane Omar
Published: July 2020

In this paper we have worked on a number of documents and articles published to find a relationship between patents and the economic growth of countries. We have found that patents and their applications are important for economic growth. The patent is not always a global indicator of all the technological knowledge produced, since a considerable number of technological know-how remains in the form of business secrets or sometimes the technology is published in scientific articles.

The patent can be an economic policy instrument to encourage investment in research and development. More patents lead to more innovations and vice versa. The patent is a vector of economic growth through the promotion of innovation.
Central and South – Eastern Europe Banking Sectors in the Sustainable Development Function
Authors: Vunjak Nenad , Dragosavac Miloš , Vitomir Jelena , Stojanović Petra
Published: July 2020

Changes in banking sectors with the onset of the global financial crisis were related to: globalization, sector deregulation, technological change and financial innovation. Structural changes within banking services (at the end of the 20th century) relate to: the consolidation of banks, the merging of banking and non-banking financial institutions and their competition with one another. Significant place in the part of sustainable development belongs to bank performance, vision and mission of banks. The corporate vision of banks should be the “framework” for the future development of a bank. The corporate mission should be a “roadmap” to the realization of the bank’s vision and an expression of the business philosophy of the bank in question.

It is of particular importance for the banking sectors of the CEE countries to define: the vision, the mission, the situational analysis and the planned long-term goals of the bank. With the advent of the global financial crisis, the financial activity of banks in the Central and Southeastern European region decreased, as the number of attractive fusion and acquisition banks in the region concerned was reduced.

The aim of the research is to determine the importance of the vision, mission and clearly set goals in banks, where the analysis of banking sectors in 13 countries over a period of 11 years was carried out. The analysis of GDP and its growth in the period from 2008 to 2018 indicates a dynamic growth in the countries of Central Europe and some countries of Southeast Europe. The analysis of the assets of the banking sector and its share in GDP indicates the dominant participation of the countries of Central and Southeastern Europe that are members of the European Union relative to the candidate countries for EU member states. Analysis of the banking sector of the influx countries shows that more than 70% of the banking market in Southeast European countries is influenced by foreign highly developed banking groups. Sustainable development can only be achieved through the active joint action of the banking sectors of the Central and Southeast European countries.

Published: July 2020

Parts of European rural development policies are meant to empower local decision makers. These policies are implemented in very different multilevel governance contexts in the member states. We question the extent to which the institutional differences at the different levels affect the implementation of LEADER (an approach for Community-led Local Development). This contributes to a better understanding of the causes and consequences of different types of LEADER implementation. The research is based on ten case studies in France, Germany and Italy. First, there is an examination of the three different administration systems and the variations of Rural Development Programmes. Based on analyses of documents and interviews with stakeholders, we analysed institutional differences in the LEADER implementation at local level.

Authors: Kapalo P. , Domniţa F. , Pop O. , Adamski M. , Voznyak O.
Published: July 2020

In the construction process of modern buildings, the aim is to achieve maximum comfort within minimum energy consumption. One of the ways to achieve this requirement is the accurate determination of the volumetric flow rate of fresh air, necessary to ensure the required indoor air quality. This study begins with the experimental determination of carbon dioxide (CO2) concentration in an office room with one occupant performing three types of activities with different levels of physical intensities. Based on these measurements, a methodology for the precise determination of the volumetric air flow rate is presented. This method was compared with another one that takes into account body parameters and is considered in this study as the most accurate. The required outdoor air flow rate for the experimental room was also determined based on the present legislations of five different countries. Comparing all the studied methods and considering as refence the method based on body parameters, it was found that the accuracy of the values is influenced by the physical intensity of the activity and that most methods generally underestimate the amount of required fresh air.
Effect of Polypropylene Fibre on the Strength of Concrete Incorporating Rice Husk Ash
Authors: Phulpoto Karim Bux , Jhatial Ashfaque Ahmed , Memon Muhammad Jaffar , Sandhu Abdul Razzaque , Sohu Samiullah
Published: July 2020

The increase in Carbon Dioxide (CO2) gas emissions during the production of cement have increased the necessity for the development of eco-friendly sustainable concrete using alternative binders. This research was conducted to study the strength behaviour in terms of compressive and flexural strength of concrete incorporating rice husk ash (RHA) as a supplementary cementitious material. RHA is a potential alternative binder due to its pozzolanic nature but it can partially replace cement to a certain amount, beyond it, the strength decreases making the concrete less viable. Therefore, to strengthen RHA-based eco-friendly concrete, Polypropylene (PP) fibres were used to reinforce concrete. Based on the results, it was observed that 5% RHA achieved higher strength than the control sample, however, a further increase in RHA content resulted in a significant decrease in strength. Concrete with 10% RHA which showed reduced strength was reinforced with PP fibres which resulted in a gain in strength.

Published: July 2020

In this article, the optimum design of a reinforced concrete solid slab is presented via the Mouth Brooding Fish (MBF) algorithm that is recently developed. It is based on mouth brooding fish life cycle. This algorithm utilizes the movements of the mouth brooding fish and their children’s struggle for survival as a pattern to find the best possible answer. The cost of the solid slab is considered to be the objective function, and the design is based on the ACI code. The efficiency of this algorithm is compared with Neural Dynamic (ND) and Particle Swarm Optimization (PSO). The numerical results indicate that the MBF algorithm can to construct very promising results and has merits in solving challenging optimization problems.
The ruin problem for a Wiener process with state-dependent jumps
Authors: Lefebvre M.
Published: July 2020

Let X(t) be a jump-diffusion process whose continuous part is a Wiener process, and let T (x) be the first time it leaves the interval (0,b), where x = X(0). The jumps are negative and their sizes depend on the value of X(t). Moreover there can be a jump from X(t) to 0. We transform the integro-differential equation satisfied by the probability p(x) := P[X(T (x)) = 0] into an ordinary differential equation and we solve this equation explicitly in particular cases. We are also interested in the moment-generating function of T (x).

Authors: Karla Hornbostel , Danner Tobias , Geiker Mette Rica
Published: July 2020

Several inspection methods can be used to assess the corrosion state of steel reinforcement in concrete. Especially for periodical field surveys and monitoring, non-destructive testing (NDT) methods are to be preferred as they do not cause any or very limited damage to the existing concrete. In this paper, the corrosion state of three reinforced concrete beams exposed to marine environment for 25 years was evaluated by measuring three parameters; electrochemical potential, concrete resistivity and corrosion rate. The measurements were performed with commercial devices. It was found that all devices are applicable for field inspections. Among the methods selected for the study, the electrochemical potential measured in a fine grid and analysed statistically offered the best possibility of evaluating the corrosion state; preferably in combination with selected excavations for determination of the level of corrosion.
Bauxite Residue as Supplementary Cementitious Material – Efforts to Reduce the Amount of Soluble Sodium
Authors: Danner Tobias , Justnes Harald
Published: July 2020

This study investigates the feasibility of using bauxite residue (BR) as supplementary cementitious material (SCM) for the cement and concrete industry. It is shown from pastes of BR and calcium hydroxide, that BR is highly pozzolanic in nature. The early hydration of cement pastes with BR is accelerated while long-term strength is reduced probably due to the alkaline nature of BR. To be used as cement replacement material in concrete, attempts have been made to reduce the alkali content of BR, in particular to reduce the chance of alkali-aggregate reactions. Co-calcination of BR with kaolin or washing and cooking of BR with calcium hydroxide or calcium hydroxide and gypsum resulted in considerable reduction of alkali content; up to 75%. At the same time the reactivity of the BR was reduced but still being higher compared to fly ash already used in the cement industry.
Results of national White Stork (Ciconia ciconia) census in Hungary in 2019
Authors: Lovászi Péter , Nagy Károly , Görögh Zoltán
Published: July 2020

A national White Stork (Ciconia ciconia) census was organised in Hungary in 2019. The 14th country-wide nest count was coordinated by MME/BirdLife Hungary, also involving local branches and volunteers of the society and national park directorates.

Altogether 5,018 nests and 2,358 White Stork nest holders without nest material were reported. 89.2% of occupied nests were built on electric poles. Although 80 years ago every third nests were found on trees, in 2019, only 6 were reported at that location. Successful pairs raised 2.62 nestlings on average, breeding success for all breeding pairs was 2.19, which is lower than typical, probably due to chilly and rainy weather during the breeding season. Based on 3,540 reported breeding pairs and former census data, the White Stork population of Hungary is estimated to be 3,860–4,020 pairs in 2019. The size of the population was ca. 15–16 thousand pairs in 1941, which halved by 1958 and decreased to 5 thousand pairs by the late 1960s. For four decades, the population fluctuated between 4,800 and 5,500 pairs but in the last twenty years, the number of breeding pairs slightly decreased in the country. The population decline is stronger in hilly areas of W Hungary, i.e. in Somogy, Vas and Zala counties is about 60%.
Data on the postbreeding migration of marked Romanian Great White Pelicans (Pelecanus onocrotalus Linnaeus, 1758)
Authors: Kiss Botond J. , Alexe Vasile , Doroșencu Alexandru C. , Marinov Mihai E.
Published: July 2020

Between 1931 and 2018 in the Danube Delta, 1,171 Great White Pelican (Pelecanus onocrotalus Linnaeus 1758) were ringed (731 with metal rings, 440 with coloured plastic rings) at breeding sites. The majority of the captured birds were flightless young individuals. From the ringed birds, 25 (2.13%) were reported as recaptured. Most were reported from Israel (28%), and the rest from 8 other countries. Recovery distance varied between 50 and 3,000 km. 19 birds (76%) were reported within half year after ringing, 2 birds (8%) within a year, and further 4 individuals (16%) were reported after a year. With the exception of a single photographed individual, all the others perished: they were shot or fell victims to accidents. These cases suggest high mortality in the young age cohort. Very little knowledge is available about the African wintering grounds; there are only two reports from Egypt and one from Southern Sudan. Traditional ringing yields little information for this species. Considerably more exact data could be expected from satellite tracking, use of other modern locating techniques and use of genetic methods. The ringing of nestlings is only possible if we can apply less aggressive methods then used to date. Besides its scientific value, the intense research on the still numerous Great White Pelican population would be justified by the outstanding faunistic, economic and cultural importance of this species.
The role of reedbeds in secondary habitats during the migration and breeding of reed warblers
Authors: Bozó László
Published: July 2020

The reedbeds provide essential habitat for many Acrocephalus and Locustella species during both breeding and migration periods. The nesting and the migration of these species have been the subject of detailed research over the past half century in the Carpathian Basin. However, these studies have focused primarily on natural habitats and large reedbeds and thus, little is known about the role of smaller habitat fragments in the migration and nesting of these species. During my work, I studied the spring and autumn migration of five passerines in a landscape dominated by agricultural land in Southeast Hungary. Field observations were carried out to survey the populations of different species between 2010–2019. To study their migration, I used the method of bird ringing between 2016–2019 in an oleaster forest and a drainage canal. I was able to determine the migration periods of the species and in autumn, to calculate the time spent in the research area based on the recaptures. In conclusion, reedbeds in secondary habitats play a similar role in the migration of the most common Acrocephalus and Locustella species as in the natural habitats in different regions of the Carpathian Basin. There are differences among species in the timing of migration, the length of time spent here, and the accumulated fat stores. As these species nest in small numbers in the area, primarily individuals from more distant populations occur here during the migration.
Foraging Eurasian Jays (Garrulus glandarius) prefer oaks and acorns in central Europe
Authors: Mitrus Cezary , Szabo Josif
Published: July 2020

The Eurasian Jay (Garrulus glandarius) is considered as the most important factor in the dispersal and spread of oak species. We conducted studies in oak stands in four countries (Poland, Hungary, Romania, Ukraine) in the autumn of 2015 and 2016. To identify the preferences of Jays for both acorns and trees, we compared the size of acorns and tree characteristics between each selected tree and the closest unused oak. We found that acorns from selected oaks were smaller (narrower) than those from unused trees. We found no differences in the characteristics of selected and unused oaks. These results indicate that the size of acorns can be an important indicator determining the choices of foraging birds. The Jays’ preferences for specific trees may influence the composition of oak populations. Trees with certain phenotypic and genomic characteristics may be favoured and dominate in the ecosystem.
A Morphosyntactic Analysis of Patient-Subject Constructions in Chinese
Authors: Wang Changsong , Zheng Mingming
Published: July 2020

The exact nature and derivation of patient-subject constructions (PSC) in Chinese are still at dispute in literature. Based on the restriction of manner adverbial modification and the nonexistence of the manner reading of zenme ‘how’ observed in Chinese PSC, a morphosyntactic analysis has been provided. We argue that the seeming action verb V in PSC is not a real main verb, but a verbal root to be introduced into the derivation after syntax via external morphological merger. The real main verb of PSC in syntax is a covert light verb ∅BEC, which selects a nominal phrase (NP) as its specifier (Spec) and a resultative phrase (RP) as its complement. BECP is further selected by an aspect (Asp) head le. To satisfy the extended projection principle (EPP), the NP at [Spec, BECP] moves to the [Spec, TP] in syntax. After syntax, the resultative (R) head-moves to ∅BEC at the phonological form (PF) to satisfy the phonological requirement of ∅BEC, forming R-∅BEC; then, a bare verbal root merges with R-∅BEC at PF to denote the manner of the change of state. Due to the phonological requirement of le, V-R-∅BEC head-moves to le, producing the right order of PSC. The two elided forms of PSC can be derived similarly. This research suggests that covert light verbs and morphology may play an interactive role in the derivation of some “typical” constructions in Chinese.

Published: July 2020

The contribution aims to identify the influence of income on Slovak household expenditures. Analyses are querying from the household income and expenditures data in the Slovak Republic during the period 2004–2018. The data source is the Statistical Office of The Slovak Republic. Descriptive statistics and regression analysis are used. The analysis of the goods and services expenditures reveals the major share of the expenditures is expended for the non-durable goods. The non-durable goods expenditures of the pensioners are 72% of their total consumption expenditures. Expenditures of employees, self-employees and other households for the non-durable goods present more than a half of their total expenditures. The share of services expenditures is also considerable. It is varying above 30% for all households kinds. The income influence on the household expenditures is analyzed using Engel’s expenditures functions which are used as the basis for the income elasticities of household expenditures. The analysis results are pointing to the fact that the less elastic on the income change is the reaction of the Slovak household expenditures on non-durable goods. A significant reaction on the income change is observed in household durable goods expenditures.

Published: July 2020

Within Hungary, the Koppányvölgye rural area was chosen due to its unique natural circumstances with its broad green nature, concerning the inhabitants’ habit for the usage and knowledge of renewable energy for residential heating. Through quota-based sampling method we collected the demographic, social and economic variables to examine their level of influence on wood for residential heating usage. We received the Likert scale values through the questionnaire, which had to be recoded for the binomial logistic regression model that we chose to use because of the indicator variable’s trait, and in aim to examine the explanatory variables’ significance. As a result, for the wood indicator variable, the age of the respondent turned out to be a significant variable, the higher age compared to lower age is a chance decreasing category for wood usage, employed compared to unemployed increased the likelihood, thereby rejected the energy ladder phenomenon, as well as more people in one household increased the chance for wood usage. The higher education, environmental awareness and insulation level of a house turned out to be non-significant for wood usage. Therefore, we strengthened those statements from the earlier studies, that in this rural region, the change of the residential heating technology is more likely to be supply driven than demand driven.
Does Working Capital Management Affect Profitability of Ghanaian Manufacturing Firms?
Authors: Prempeh Kwadwo Boateng , Peprah-Amankona Godfred
Published: July 2020

This paper analyses the link between working capital management and profitability of firms in the context of developing economies. A balanced panel consisting of eleven (11) manufacturing firms listed on the Ghana Stock Exchange covering the period of 2011-2017 was used. The link between working capital management and profitability was examined using dynamic panel regression (Arellano-Bond Estimation) technique. The study revealed that there is a significant positive linear relationship between working capital management and firms’ profitability. The findings also reveal the existence of a concave quadratic relationship between working capital management and firms’ profitability. There is an optimal level at which working capital management maximises firm’s profitability, therefore, managers need to ensure that they operate within the limits of the optimal level by implementing an effective and efficient working capital management policy. The study concludes that, the practice of an aggressive working capital management policy maximises a firm’s profitability.

The analysis of the regularities characterizing the existing rate of female early-stage entrepreneurial activity, as well as the identification of reserves for female entrepreneurship growth is relevant nowadays. The purpose of the work is to assess the rates of entrepreneurial activity of women, their motivational preferences, and comparative analysis of female and male early-stage entrepreneurial activities. The study is based on the economic analysis of the data on 48 countries, presented in the Global Entrepreneurship Monitor report for 2018. Normal distribution density functions are used in the modeling process. The research reveals features of female entrepreneurship and the barriers to its development. The paper defines countries with high and low values of the considered indicators. The study estimates the existing rates of opportunity and necessity motivation of female entrepreneurs, presents the analysis of the ratio of female to male participation in early-stage entrepreneurial activity, and proves the hypothesis on substantial differentiation of these indicators across countries. The obtained knowledge can be used in future scientific research, in the educational process of bachelors and masters training. The scientific novelty lies in the study of the distribution of indicators characterizing female entrepreneurs’ motivation and the existing gender gap in early-stage entrepreneurship. The study proposes new methods and tools for the analysis and presents a comparative analysis of the development of female and male early-stage entrepreneurship.

We identified a notable lack of academic literature on the issue of third-country auditors and the main contribution of our article is to address this gap. This research builds on adjacent audit oversight and capital markets literature and we extend this literature by providing evidence on third-country auditors. Specifically, we test the relationship between market capitalization and number of foreign IPOs of listed companies in representative EU countries (on one hand) and the existence of third-country auditors in those respective countries (on the other hand). Our research was performed in the second half of 2018 and is based on the latest data available. We have found that there are about 200 third-country auditors present in the public registers of audit oversight bodies in 11 EU countries. According to our network analysis, only European countries with a developed capital market have attracted third-country auditors. Most of the relationships of these developed EU capital markets are nurtured with non-EU capital markets that are at the same level of development (e.g. USA, Switzerland, Canada, Israel, and Australia). Our research hypotheses were validated: (1) the higher the market capitalization of a EU country, the higher the likelihood for the registration of third-country auditors; (2) the higher the number of foreign IPOs relative to the total IPOs on the stock exchange market, the higher the likelihood for the registration of third-country auditors.

This article characterizes a dynamic crude oil trade network of Eastern Europe and Eurasia using the network connectedness measure of Diebold and Yilmaz (2014, 2015) and asymmetric reaction of crude oil bilateral trade flow in response to the positive and negative changes of its key determinants using the nonlinear panel ARDL model. Results indicate the existence of large and time-varying spillovers with a considerable explanatory power among the crude oil trade flow volatility of Iran, Russia, US and Saudi Arabia in Eastern Europe and Eurasia crude oil trade network. The findings also show that crude oil trade flow of Eastern Europe and Eurasia experiences net volatility transmission to Iran, Russia and US respectively, whereas it is a net volatility receiver from Saudi Arabia. Also based on gravity models, the analysis confirms the existence of impact, reaction and adjustment asymmetry through different magnitude among network participants.
A Dádiva como Prática Social
Authors: Júlio Ana Carolina
Published: July 2020

Este artigo analisa como outras possibilidades de relações sociais, marcadas pela honra, respeito, afeto e reciprocidade, influenciam a vida social e o processo organizativo (organizing)de uma escola de samba. Para compreender esses fenômenos, as ideias de Schatzki e Mauss são utilizadas. Está é uma pesquisa qualitativa que triangula observação participante, entrevistas e pesquisa documental. Durante o carnaval, o objetivo da escola foi honrar o pavilhão e a memória do seu presidente, retribuindo a dádiva que se recebeu: o prazer de desfilar, a amizade e a família. Assim, as dádivas revelaram-se como uma prática social, sendo marcadas pelas teleoafetividades. Os objetivos de uma organização podem ir além de seus resultados instrumentais/racionais, coexistindo com sentimentos, emoções e humores. As teleoafetividades também podem orientar o que as pessoas fazem; sendo as dádivas exemplos de práticas norteadas por essa dinâmica afetiva.

O objetivo do estudo foi verificar se há correlação entre o uso de questões de avaliações como Exame de Suficiência e ENADE em sala de aula por professores na área contábil e o desempenho dessas instituições nas referidas avaliações. Para tal, realizou-se uma pesquisa descritiva, valendo-se de um questionário fechado aplicado entre docentes vinculados aos departamentos de ciências contábeis de Universidades Federais localizadas no Nordeste. Verificou-se que os professores participantes da pesquisa preferem usar em sala de aula questões de elaboração própria, valendo-se do modelo de perguntas objetivas. No entanto, o uso desse tipo de questões diminui à medida que a titulação do docente cresce. Percebeu-se ainda que as instituições onde seus professores destacaram um maior uso de questões de ENADE, Exame de Suficiência e concursos públicos em sala de aula são aquelas que obtêm resultados mais baixos nas avaliações do Ministério de Educação e do Conselho Federal de Contabilidade. Esta pesquisa foi útil para promover uma reflexão entre o corpo docente das instituições de ensino superior, fazendo-os pensar sobre como deve ser a postura em sala de aula, se de treinador para provas específicas ou se de orientador para que o estudante seja autônomo em seu processo de ensino-aprendizagem

BACKGROUND: According to WHO, around 73% of maternal deaths globally are caused by direct obstetric causes. The amniotic fluid embolism is a life-threatening obstetric emergency characterized by sudden cardiopulmonary system failure and can be accompanied by Disseminated Intravascular Coagulation (DIC). The amniotic fluid embolism event usually occurs during labor and birth, but can also occur immediately in the post partum period or after pregnancy termination. About 56% of women will not survive for first 2 hours after the acute event. Amniotic fluid embolism is an unpredictable event, so that no prophylactic intervention can be carried out effectively and the handling and enforcement of a diagnosis that still debatable.OBJECTIVE: To report maternal deaths due to amniotic fluid embolism post cesarean sectionMETHOD: Case ReportCASE:  Reported case of a 30 years old woman with an initial diagnosis in emergency departement with decreased consciousness due to Severe hypoxia due to Pulmonary emboli due to Amniotic fluid emboli on P2A0L2 post Cesarean Section first day of puerperium. The patient experienced a sudden loss of consciousness accompanied by severe shortness of breath after 6 hours after cesarean section surgery in a private hospital. After initial examination and treatment by administering oxygen through the Nonrebreathing Mask, there was no improvement in the O2 saturation value and then the patient was intubated by the anesthetist. After intubation, the O2 saturation value still does not increase, then the patient suddenly experiences cardiac arrest and followed with cardiac resuscitation for 2 cycles accompanied by resuscitation drugs then the patient returns to spontaneous circulation. From the cardiology department, inotropic therapy was given and echocardiographic investigations were carried out. On echocardiographic examination, they found McConnel's sign which showed suspicios of pulmonary embolism. At the time the patient will be moved to the intensive care unit, the patient experiences a cardiac arrest for the second time, then resuscitation is performed again for 2 cycles, but it does not work and the patient is declared dead.CONCLUSION: Amniotic fluid embolism is an obstetric emergency condition that cannot be predicted and has a high mortality rate. Treatment is supportive to support the cardiopulmonary system and management of coagulopathy that may occur.KEYWORDS: Maternal mortality, Amniotic Fluid Embolism
