The article reflects the main directions of forming a new regulatory environment for relations arising with the development of the digital economy, including in the field of tax regulation. Today, in order to perform their main functions, including ensuring a high level of cash receipts to the budget system, one of the key areas of work for tax authorities is not just adapting to changes caused by the development of the digital economy, but directly managing the processes of digitalization. The authors researched the impact of the digitalization process in Germany on the transformation of the approach to public administration, which aims to expand the digital infrastructure, both in the public and private sectors. The main factors that have had a significant impact on the formation of legal regulation in Germany in the context of the development of the digital economy, including in the field of taxation, are considered. Among key findings of the research we should mention formulation of practical recommendations for institu-tional improvement of tax regulation in Russia, developed on the basis of rethinking the experience of Ger-many in managing relevant changes.

TAX BURDEN: PRINCIPLES AND EFFECTIVE WAYS OF OPTIMIZATION
Authors:   Candidate of Economic Sciences, Associate Professor of the Department of Taxes and Tax Administration, Financial University under the Government of Russia, Moscow, Russia, NAZAROVA N. A.
Published: April 2021

The article examines the assessment and existing methods of the tax burden, directions of its optimiza-tion. One of the main systemic elements of the country's state policy is the tax system as one of the vectors in the direction of economic and social development. The legal basis of the state determines that an economic entity becomes a taxpayer, paying taxes and fees to the state budget system. For effective conduct of activi-ties, organizations need to assess the amount of taxes paid to the budget and determine how much of their own resources they can donate to the state as payment for using its services. For this, it is advisable to use the estimated indicator "tax burden". In addition to organizations, the tax burden is also calculated by the tax authorities to control the activities of taxpayers. It is important for the state to monitor both the direction of movement of tax flows and the fact of their receipt into the country's budget, taking into account the financial and economic capabilities of taxpayers, since tax revenues form a significant part of the federal and consoli-dated budget revenues.
Kein Ende, sondern eine Veränderung des Städtischen

Published: April 2021

In meinem Kommentar möchte ich auf die Symptomanalyse und These der Autoren mit zwei Gegenbeobachtungen und -thesen antworten: (1) Wir haben es mit einer Neuformierung sozialer Interaktionen zu tun, die maßgeblich von Digitalisierung geprägt ist. (2) Wir beobachten eine Restrukturierung des öffentlichen Raums und dessen, was als Öffentlichkeit konzipiert wird. Dabei haben wir es weniger mit dem Ende des Städtischen als mit einer potenziellen Transformation des Städtischen zu tun, dessen Merkmale wir noch nicht voraussehen können.

Objective: To describe the number of confirmed cases and deaths by COVID-19 in the State of
Maranhão. Descriptive, documentary and retrospective study, using secondary data extracted
from the COVID-19 Epidemiological Bulletin of the State of Maranhão from April 1st to
September 30th. The following were considered: confirmed cases of COVID-19, deaths by age
group, date of occurrence, associated comorbidities. The data are public and are available in the
health system's online bulletins. There were 173,564 confirmed cases and 3,756 registered deaths.
The evolution of COVID-19 cases by date was greater on September 2, totaling 1,787 cases in
that period. The evolution of deaths by date shows that the months of July and August had the
highest rates of death records by COVID-19, with a fall in the month of September. Higher rates
of confirmed cases occurred in men. Deaths occurred more in the elderly over 70 years of age.
Arterial hypertension and diabetes mellitus were the most comorbidities related to deaths. It is
concluded that this research contributes to a greater reflection that COVID-19 has negative
proportions and impacts for the population and mainly for the elderly population, where the
highest death rates occurred exactly in the elderly

Optimal Factorization of the State-Dependent Riccati Equation Technique in a Satellite Attitude and Orbit Control System
Authors: Romero Alessandro Gerlinger , De Souza Luiz Carlos Gadelha
Published: April 2021

The satellite attitude and orbit control system (AOCS) can be designed with success by linear control theory if the satellite has slow angular motions and small attitude maneuver. However, for large and fast maneuvers, the linearized models are not able to represent all the perturbations due to the effects of the nonlinear terms present in the dynamics and in the actuators (e.g., saturation). Therefore, in such cases, it is expected that nonlinear control techniques yield better performance than the linear control techniques. One candidate technique for the design of AOCS control law under a large maneuver is the State-Dependent Riccati Equation (SDRE). SDRE entails factorization (that is, parameterization) of the nonlinear dynamics into the state vector and the product of a matrix-valued function that depends on the state itself. In doing so, SDRE brings the nonlinear system to a (nonunique) linear structure having state-dependent coefficient (SDC) matrices and then it minimizes a nonlinear performance index having a quadratic-like structure. The nonuniqueness of the SDC matrices creates extra degrees of freedom, which can be used to enhance controller performance, however, it poses challenges since not all SDC matrices fulfill the SDRE requirements. Moreover, regarding the satellite's kinematics, there is a plethora of options, e.g., Euler angles, Gibbs vector, modified Rodrigues parameters (MRPs), quaternions, etc. Once again, some kinematics formulation of the AOCS do not fulfill the SDRE requirements. In this paper, we evaluate the factorization options (SDC matrices) for the AOCS exploring the requirements of the SDRE technique. Considering a Brazilian National Institute for Space Research (INPE) typical mission, in which the AOCS must stabilize a satellite in three-axis, the application of the SDRE technique equipped with the optimal SDC matrices can yield gains in the missions. The initial results show that MRPs for kinematics provides an optimal SDC matrix.

Published: April 2021

Recently, a new drug, called „bika” (bull) in Hungarian, received considerable media attention. The drug is notorious for driving its consumers into a deep state of delirium and even killing some of them. Law enforcement seizures revealed that the „bika” was in fact the synthetic cannabinoid called 4F-MDMB-BICA, which was identified for the first time in Hungary at the end of May 2020. Here we describe the effects and mechanism of action of the „bika”, identify its very close „relatives”, and provide a domestic and international overview of the specifics of its use. The main aim is to draw attention on the presence of this drug on the illegal market. The article is for police professionals who are not necessarily familiar with the neurobiology of drugs; therefore, we start with the basics and reveal neurobiological details gradually to provide means for understanding of this new drug.

Published: April 2021

The development of applied geodetic techniques for mapping and documentation of historical structures, buildings and sites is an important and vital purpose for contribution of any recording of cultural heritage for any country such as Egypt. This is done to preserve and restore any valuable architectural or other cultural monument, as a support to architectural, archaeological and other art-historical research throughout the ages. The purpose of this paper is to use close range photogrammetry technique (CRP) to reconstruct 3D model of architectural and historical mosque facade and comparing the accuracy of using digital commercial non-metric cameras with different resolutions and metric camera with flatbed scanner and photogrammetric scanner for architectural building documentation. El-Nasr Mosque façade in Mansoura city, Egypt was chosen as a case study in this paper. At first, twenty five points were selected at mosque façade at different elevations and distributed at different façade surfaces and observed using total station. Some of these points were selected as control points and the others were selected as check points to validate the results. Effect of control point’s number on image processing and analysis is also studied. Three cameras positions were selected for imaging to get the full details of mosque façade. Close range Digital Workstation (CDW) program was used for processing and analysis of multiple images. The results are indicated that close range photogrammetry using metric camera with photogrammetry scanner instead of flatbed scanner in technique is accurate enough to be beneficial in 3D architectural building documentation. Digital cameras with CRP technique give up different accuracy that depends mainly on the resolution of cameras and camera specifications.

Karyotypes of four catfishes of the genus Mystus Scopoli, 1777 (family Bagridae), M. atrifasciatus Fowler, 1937, M. mysticetus Roberts, 1992, M. singaringan (Bleeker, 1846) and M. wolffii (Bleeker, 1851), were analysed by conventional and Ag-NOR banding as well as fluorescence in situ hybridization (FISH) techniques. Microsatellite d(GC)15, d(CAA)10, d(CAT)10 and d(GAA)10 repeat probes were applied in FISH. The obtained data revealed that the four studied species have different chromosome complements. The diploid chromosome numbers (2n) and the fundamental numbers (NF) range between 52 and 102, 54 and 104, 56 and 98, or 58 and 108 in M. mysticetus, M. atrifasciatus, M. singaringan or M. wolffii, respectively. Karyotype formulae of M. mysticetus, M. atrifasciatus, M. singaringan and M. wolffii are 24m+26sm+4a, 26m+24sm+2a, 24m+18sm+14a and 30m+22sm+6a, respectively. A single pair of NORs was identified adjacent to the telomeres of the short arm of chromosome pairs 3 (metacentric) in M. atrifasciatus, 20 (submetacentric) in M. mysticetus, 15 (submetacentric) in M. singaringan, and 5 (metacentric) in M. wolffii. The d(GC)15, d(CAA)10, d(CAT)10 and d(GAA)10 repeats were abundantly distributed in species-specific patterns. Overall, we present a comparison of cytogenetic and molecular cytogenetic patterns of four species from genus Mystus providing insights into their karyotype diversity in the genus.

Authors: Marcus Jessica A. , Clark Patricia C.
Published: April 2021

Background:

When evaluating new technology designed to improve patient care quality and safety in the clinical setting, researchers need instruments with evidence of reliability and validity. This secondary analysis aimed to examine the reliability and validity of the Positive and Negative Effectiveness of Technology Use (PNET) instrument.

Method:

A sample of 71 nurses evaluated the current telephone interpretation system in use for persons with limited English proficiency. Internal consistency reliability using Cronbach's alpha and construct validity using factor analysis tests were assessed.

Results:

Both positive and negative scales of the PNET instrument had adequate internal consistency reliability coefficients (α > .70) and evidence of construct validity; however, some items on the negative effectiveness scale may need to be revised.

Conclusion:

The PNET scales may be useful in assessing nurses' views of existing and new technologies for quality improvement in the practice setting.

The loss-averse newsvendor problem with quantity-oriented reference point under CVaR criterion
Authors: Liu Wei , Song Shiji , Qiao Ying , Zhao Han , Wang Huachang
Published: April 2021

This paper studies a single-period inventory problem with quantity-oriented reference point, where the newsvendor has loss-averse preferences and conditional value-at-risk (CVaR) measure is introduced to hedge against his risk. It is shown there exists a unique optimal order quantity maximizing the CVaR of utility. Moreover, it is decreasing in loss aversion level, confidence level and target unit profit, respectively. Then we establish the sufficient conditions under which the newsvendor's optimal order quantity may be larger than, equal to or less than the classical newsvendor solution. In particular, when the target unit profit is a convex combination of the maximum and minimum, the optimal order quantity is independent of price and cost parameters. Numerical experiments are conducted to illustrate our results and present some managerial insights.
The impacts of retailers' regret aversion on a random multi-period supply chain network
Authors: Zhou Yan , Chan Chi Kin , Wong Kar Hung
Published: April 2021

Most current studies on the equilibrium decision-makings of a supply chain network (SCN) consider only completely rational retailers who always try to maximize their expected profits under the situations that demands are random. However, many evidences show that a retailer wants to choose the decision-making involving random demand which provides him with minimum regret. In this paper, we consider the impacts of retailers' anticipated regret aversion and experiential regret aversion on the equilibrium decision-makings of a random SCN with multiple production periods. Due to the random demand, the decision-makings of retailers are influenced not only by their anticipated regret, but also by their experiential regret after they have encountered bad or good experiences during past periods. The equilibrium conditions of the model are established. A numerical example is solved to illustrate the benefit of retailers obtained by considering their regret-averse behaviors. Moreover, it is found that retailers should consider their anticipated regret aversion or experiential regret aversion according to different situations of the demand markets.
Optimal return and rebate mechanism based on demand sensitivity to reference price
Authors: Han Junling , Wang Nengmin , He Zhengwen , Jiang Bin
Published: April 2021

The acceleration of electronic products' upgrade affects consumers' purchase behaviour. How to encourage consumers to return old products in order to upgrade to new products and how to optimize such the closed-loop supply chain are important managerial topics. According to the theory of reference price, the closed-loop supply chain model with fixed rebate and variable rebate is established. The analysis results imply that, when consumers' willingness to return second-hand products depends on manufacturers' rebates and prices of new products, the profit of closed-loop supply chain decreases. In addition, when consumers are sensitive to price difference, enterprises can adopt low profit margin methods to increase new product demand. Furthermore, the profit of the manufacturer is closely related to whether consumers are loss-seeking or loss-averse. Finally, our analysis provides the insights of the relationship between the optimal return and rebate mechanism and the use time of the previous generation of products.
Circular-Green Economy
Authors: Vargas-Hernández José G.
Published: April 2021

The purpose of this chapter is to analyze the green and circular economy (GCE) model from the point of view of the resources and capacities of the organization. How is the application of the circular economy model related to strategic management? At first glance, it seems that the CE is operating within an operational level with a social impact, but it also has implications that allow us to think that it can be used as an internal resource of the company that, if applied in the right way, it can become a competitive advantage; in other words, the application of the CE is related to strategic management through the point of view based on resources and capabilities. Therefore, the present investigation has a descriptive-correlational nature, which was analyzed through Peng's VRIO framework.
Protection of Intangible Heritage
Authors: Jhamb Vinayak , Kaur Konpal
Published: April 2021

The convention concerning the protection of cultural and natural heritage only emphasizes the protection of tangible cultural heritage. However, the present convention completely turned a blind eye and a deaf ear to the intangible cultural heritage. “Cultural heritage” as a term and its content are largely taken from other fields like anthropology and archaeology. The legal aspect of cultural heritage is most complex and difficult to understand. There also exist elements of intangible culture which would include songs or folklore musical traditions, ceremonial or ritual traditions, aspects of the life of ancient societies, and any special relationship between the people and the land that they inhabited. With the term property also comes the idea of assigning the artifact a market value whereas they are historically priceless. Cultural heritage has been made global and a part of universal heritage or “common heritage of mankind.”

Authors: Thwaite Sapna V.
Published: April 2021

This chapter explores the impact of motherhood on the professional identities of female leaders during the COVID-19 pandemic. It focuses on five principles related to parenting a young child that one might apply to one's experiences as a female leader during the COVID-19 pandemic: 1) listen with your eyes, 2) recognize that not knowing is part of growing, 3) release the need for perfection, 4) engage in restorative rituals, and 5) focus on those things that are within your control. It also expands upon the notion that creating an emotional climate where faculty, staff, and administrators can bring their “whole selves” to work would be beneficial, both during a pandemic and beyond.
Who Am I?
Authors: Haslett Beth Bonniwell
Published: April 2021

This chapter focuses on how culture and the new media shape one's identity. While culture and one's family initially shape one's identity, the new media provide new ideas and lifestyles that influence one's identity. One's identity changes throughout one's lifespan, and the new media presents more information and alternative lifestyle choices for individuals. Identity itself is a complex concept and the self is viewed as the continuing, consistent narrative that one presents over one's lifetime and over different contexts. The new media enable people to develop online identities, and such identities may be authentic or inauthentic when compared to one's real life identity. The new media present different venues for developing and expressing one's self. The new media also enable individuals to maintain cultural and identity links with their home culture although they may have located elsewhere in the world.

This chapter intends to discuss the experiences of international college students regarding racial prejudice on campus and explore the role of student associations as a way to increase cross-cultural interactions between domestic and international students. The aim is to examine how prejudice, more specifically racial-ethnic prejudice, affects their college experience. The findings suggest that active involvement in campus activities promote interaction across cultures and reduce racial prejudice. This chapter engages qualitative individual interviews with Chinese, Japanese, Korean, and Nigerian, Kenyan, and Ghanaian undergraduate international students (N=31). It is believed that this method is best suited to apprehend their experiences and to fully understand how they create meaning of perceived racial prejudice. Their testimonies are presented through verbatim transcripts of the interview sessions conducted in 2014-2015, in three New York research universities. A discussion of their experiences follows and suggestions for future research conclude this chapter.

Early detection of breast cancer is critical to improve treatment efficiency and chance of cure. Mammography is the main method for breast cancer screening; however, it has some limitations. Infrared thermography is a technique that is being studied for its benefits. The existing tumor classification systems are detailed, complex, and have low usability. Therefore, combining specialized professionals with methods of digital image analysis using thermography can help improve the diagnosis. Considering this, some computational areas are working on studies and creating methods to assess these data. The features selection plays a key role in this process, as it is a way to help solving data multidimensionality problems. This study aims to reduce the amount of features from thermographic images with mammary lesions. The authors used genetic algorithm and particle swarm optimization for features selection and compared the performance of each method to the performance using the entire set of features.

Knowledge discovery data (KDD) is a research theme evolving to exploit a large data set collected every day from various fields of computing applications. The underlying idea is to extract hidden knowledge from a data set. It includes several tasks that form a process, such as data mining. Classification and clustering are data mining techniques. Several approaches were proposed in classification such as induction of decision trees, Bayes net, support vector machine, and formal concept analysis (FCA). The choice of FCA could be explained by its ability to extract hidden knowledge. Recently, researchers have been interested in the ensemble methods (sequential/parallel) to combine a set of classifiers. The combination of classifiers is made by a vote technique. There has been little focus on FCA in the context of ensemble learning. This paper presents a new approach to building a single part of the lattice with best possible concepts. This approach is based on parallel ensemble learning. It improves the state-of-the-art methods based on FCA since it handles more voluminous data.

Medical data analysis is being recognized as a field of enormous research possibilities due to the fact there is a huge amount of data available and prediction in initial stage may save patient lives with timely intervention. With machine learning, a particular algorithm may be created through which any disease may be predicted well in advance on the basis of its feature sets or its symptoms can be detected. With respect to this research work, heart disease will be predicted with support vector machine that falls under the category of supervised machine learning algorithm. The main idea of this study is to focus on the significance of parameter tuning to elevate the performance of classifier. The results achieved were then compared with normal classifier SVM before tuning the parameters. Results depict that the hyperparameters tuning enhances the performance of the model. Finally, results were calculated by using various validation metrics.

Published: April 2021

The COVID-19 pandemic caused children to distance learn at home, but with technical and pedagogic difficulties. Digital learning games offer effective tools for pedagogic difficulties, such as active and relevant learning. Using mixed-methods research, this study examined 1) parents' perceptions about digital learning games and 21st century skills and 2) parents' attitudes towards digital learning games instead of traditional homework. The findings are based on both qualitative (in-depth interviews) and quantitative (online survey) data. The results of the study revealed that parents do not object to replacing traditional homework with digital learning games. They saw digital learning games as relevant for their children's digital lives and acknowledged their potential to reduce arguments over homework. Therefore, digital learning games should be employed in school and as an alternative for traditional homework, both in routine and crisis, such as the COVID-19 pandemic.

The educational system has moved towards digitization and online learning in the past two decades. The institutions are focusing on delivering online courses to facilitate the students. Uttarakhand Open University offered online courses to reach the unreached learners. High dropout rate from MOOCs is a global concern. Learners' satisfaction survey is one of the important instruments to investigate the reasons of discontinuance from an online course. Detailed analysis of learners' satisfaction survey will help the educators understand learners' expectations from the course and they can work on these factors which leads to increasing the learners' satisfaction with MOOCs and thereby address high-dropout rates from MOOCs. This paper investigates the students' satisfaction of online courses on academic counselling, assignments, and examination marking process and various support services provided by the university. A structed questionnaire of 5-point Likert scale was administrated using Google form. The data (269 valid responses) have been analysed quantitatively by implying statistical measures. The findings show that academic counselling provided by the university to students are conceptual, clear, and knowledgeable. The students are comfortable on assignment, examination, and their result declarations. Along with this the online services, different initiatives and other support services provided by university are discussed in detail and suggested for further enhancements. Furthermore, it is also concluded that the study center structure is adequate, and personnel at study center are very helpful with students.

Background:

Perls Prussian blue stain (PPB) for hemosiderin, a marker of vascular injury is often employed as an adjunct in the diagnosis of vasculitic neuropathies. However, inflammation/vascular injury is also seen in leprosy, immune mediated, paraproteinemic, diabetic neuropathies, etc. The frequency of detection of hemosiderin in these neuropathies and its utility in diagnosis of vasculitis has not been explored.

Objective:

We evaluated 208 peripheral nerve biopsies for hemosiderin deposits by PPB stain in vasculitis (78) and compared with inflammatory/immune neuropathies [leprous neuritis-32, chronic inflammatory demyelinating polyneuropathy (CIDP)-15, paraproteinemic neuropathies (POEMS)-12, diabetic neuropathy-37] and nonimmune neuropathies [Charcot-Marie-Tooth (CMT) disease-15, vitamin B12 deficiency-7, and ischemic neuropathy in aged-12)].

Results:

Hemosiderin deposits were most frequent in vasculitis (48.72%) [59.2% in systemic; 43.1% in nonsystemic vasculitides] and enhanced the sensitivity of diagnosis in “probable” vasculitis (34.48%) that lacked transmural inflammation. Hemosiderin was also detected in infectious/immune-mediated neuropathies (leprous neuritis-56%, POEMS-33.3%, diabetes-18.9%) but absent in CMT, B12 deficiency, and ischemic neuropathy. Hemosiderin deposits involved epineurium in vasculitis, compared to endoneurial/perineurial location in leprosy and perineurial in POEMS and diabetic neuropathy. The sensitivity of detection was high in vasculitic neuropathy (49.35%) compared to other inflammatory neuropathies (22.3%) (P < 0.05) with high specificity (77.69% [positive predictive value (PPV)-56.71%; negative predictive value (NPV)-71.6%]. The specificity increased to 89% if leprous neuropathy was excluded, with PPV-77.5% while NPV dropped to 68.5%.

Conclusion:

These findings suggest that PPB stain for detection of hemosiderin is a useful adjunct in diagnosis of vasculitic neuropathy with high specificity but low sensitivity.

Published: April 2021

We report about two young males who developed significant proximal weakness of all four limbs secondary to intracranial hypertension due to intracranial venous sinus thrombosis. Intracranial venous sinus thrombosis can manifest in a variety of ways which includes isolated intracranial hypertension, focal neurological symptoms or signs and acute or subacute encephalopathy. Various false localising signs have been reported to occur in patients with raised intracranial pressure including cranial nerve palsies and extensive radiculopathy. In a patient presenting with flaccid areflexic quadriparesis and papilledema, the possibility of a potentially reversible dysfunction of the cranial nerves and spinal nerve roots due to a marked rise in intracranial and intraspinal pressure must be recognised. Lumboperitoneal shunt to reduce the intraspinal pressure on the spinal nerve roots has been advocated to reverse the symptoms of extensive radiculopathy in such patients. Both of our patients showed remarkable improvement in symptoms and signs with medical treatment of CVT.
