Enhanced Image Inpainting in Remotely Sensed Images by Optimizing NLTV model by Ant Colony Optimization
Authors: Singh Manjinder , Kaur Harpreet
Published: July 2021

Filling dead pixels or eliminating unwanted things is typically preferred within the applications of remotely sensed images. In proposed article, a competent image imprinting technique is demonstrated to resolve this drawback, relied nonlocal total variation. Initially remotely sensed images are effected by ill posed inverse problems i.e. image destripping, image de-noising etc. So it is required to use regularization technique to makes these problems well posed i.e. NLTV method, which is the combination of nonlocal operators and total variation model. Actually this method can make use of the good features of non-local operators for textured images and total variation method in edge preserving for color images. To optimize the proposed variation model, an Ant Colony Optimization algorithm is used in order to get similarity with the original image. And evaluate the outcomes of proposed technique with the existing technique i.e. MNLTV optimized by Bregmanized-operator-splitting algorithm which is a prediction based method. The investigation of all outcomes confirms the efficacy of this rule.
Inverse Approach for the Average Convection Coefficient Induced by a Forced Fluid Flow Over an Annular Fin of Rectangular Profile Using Tip Temperature Measurements
Authors: Campo Antonio
Published: July 2021

The objective of the present paper is to develop a simple algebraic computational procedure for the estimation of the average convection coefficient of a forced fluid flow over an annular fin of rectangular profile within the platform of inverse heat conduction problems. The data required is the tip temperatures of an annular fin of rectangular profile, which are measured in an experimental setup. Based on nonlinear regression analysis, an empirical correlation equation is constructed for the dimensionless average tip temperature depending upon the dimensionless thermo–geometrical parameter and the radius ratio. When compared against the outcome of a direct heat conduction problem, the good quality of the estimated average convection coefficient for the annular fin of rectangular profile demonstrates the feasibility of the simple algebraic computational procedure.

Published: July 2021

The new reality created by the COVID-19 caused a lot of changes in the educational sphere. The transition from face-to-face to distance learning was not smooth in Ukraine because distance learning was not a common practice in the country before and teachers were unprepared for teaching online. This unusual situation prompted us to start our qualitative research primarily to get insights into the altered daily routines of teachers and educators. In particular, we were interested in how they assessed their students’ performance online. This article focuses on secondary school language teachers (n=65) and language tutors at the tertiary level (n=18). The research findings have revealed that teachers gave feedback through different digital applications like Google Classroom. Oral performance was evaluated either synchronously or asynchronously. The most crucial implication is that teachers should improve and further develop their digital skills and distance teaching and assessing skills in order to provide quality education in the modern form.
Tablets in Hungarian Primary Schools
Authors: Czékmán Balázs , Kocsis Judit , Abari Kálmán
Published: July 2021

The increasing interest in introducing tablets into education as well as many countries’ education policies (see Digital Education Strategy) support the integration of the above-mentioned mobile devices (Mulet, van de Leemput & Amadieu, 2019). Accordingly, several governments are presently procuring or have already supplied a significant number of students with these devices (Tamim et al., 2015). Similar to most international large-scale initiatives, there are remarkable variances in tablet-supported education. The different school conditions (infrastructure, framework, human resources) result in the diversity of technological integration. In our research, in order to learn more about the infrastructural conditions at schools’ institutional levels, with online questionnaires we examined 145 primary schools using tablets in their education. We were looking to answer the following, questions: (1) what kind of infrastructural conditions are characteristic of the different institutions? (2) What kind of differences in infrastructural conditions are there between the schools in different settlements? To sum up the results, we can observe significant differences in the number of tablets, their hardware, accessories and software, along with differences in internet access and the regulation thereof.
Differences in Foreign Language Choice of Students from Different Social Backgrounds
Authors: Sebestyén Krisztina
Published: July 2021

According to previous research (e.g. Bernstein, 1971; Gogolin, 2014; Hegedűs et al., 2019), family background plays a decisive role in an individual's mother tongue acquisition and in learning foreign languages. In another study, parents with a high social background (54.0%) chose German for their children, and parents with a low social background (56.9%) chose English in primary school (Sebestyén, 2021). Based on this, in the study I examine what difference can be detected in the foreign language choice of high school students from different social backgrounds. In the study, I analyze the student data (890 people) of my database entitled “German learning and teaching in Hajdú-Bihar and Szabolcs-Szatmár-Bereg counties” prepared in the 2018/2019 school year, during which I perform cross-tabulation and cluster analysis with the help of SPSS program. The database contains data on 11th grade high school and vocational high school students who studied German and / or English in high school. As the results, there are differences between the learned foreign languages among secondary school students according to family background. Among the clusters related to high school choice, those belonging to the “Higher Education Oriented Local” cluster are most interested in foreign languages, most German-speaking (74.0%) and English (89,0%) students tend to be in this cluster. Overall, the majority of respondents learn English, while students from higher social backgrounds (also) learn German.

Published: July 2021

This study aims to determine the effect of the effectiveness of promotion through instagram and product innovation on purchasing decisions for Gembul Banana products. The study was conducted because the results of several previous researchers found that product innovation and promotion are key factors in influencing purchasing decisions. The tight business competition that comes from businesses for similar products or substitute products, requires a business to always move faster and creatively to come up with new ideas in order to attract the attention of consumers. The method used in this research is descriptive explanatory method. Analysis of the data used using multiple linear regression analysis model. The population in this study were all buyers of Gembul Banana products by taking a sample of 101 respondents, and taking the sample using accidental sampling technique. The results showed that the effectiveness of promotion through instagram and product innovation had a positive effect on purchasing decisions for Gembul Banana products. Based on the results of this study, it is suggested to Gembul Banana business owners to be more serious in managing Gembul Banana social media, especially in posting photos, endeavor to post photos that are interesting and in accordance with consumer desires, not just photos and uploads on social media. In addition, it is also recommended that the logo of the company should be included on the packaging, not only in the form of a yellow box that is identical to a banana, but a logo must be included so that consumers can remember the product.

In order to account for the technical improvements in aircraft design over the last two decades and the resulting changes in the composition of air traffic, the German Aerospace Center (DLR) was commissioned by the German Environment Agency to update the underlying database and to work out proposals to enhance the AzB calculation methods. This article describes the procedure for defining new aircraft groups, as well as the method for developing the associated operational and acoustic datasets.
Crust of the Hadean Earth
Authors: Arndt Nicholas , Chauvel Catherine
Published: July 2021

High temperatures in the interior of the young Earth led to the initiation of melting at great depths in the mantle (> 150 km) and the production of large volumes of magma that erupted to form a >40 km thick basaltic crust. The ubiquitous presence of this crust dominated Archaean tectonics. Granitoid rocks, the source for >4 Ga Western Australian zircons, formed by partial melting at the base of the crust during the first 600 Ma of Earth history, but were always subordinate to basalt. The lunar record provides evidence that both the Moon and Earth experienced major impacting during this period. The impacts mixed granitoid with mantle-derived basalt to produce a composite granitoid-basalt layer with isotopic composi­tions close to bulk-Earth values. No record of its existence was retained in the oldest extant continents which formed - 3.9 Ga ago, after major impacting had ceased.
The Archaean gneiss complex of northern Labrador A review of current results, ideas and problems
Authors: Bridgwater D. , Schiøtte L.
Published: July 2021

1.
The early Archaean rocks in northern Labrador can be subdivided into the ea. 3.78 Ga Nulliak supracrus­tal association, the migmatitic Uivak I gneisses, the dominant phase of which was emplaced at ea. 3.73 Ga, and the Uivak II augen gneiss. Inherited low-U rounded inclusions within igneous zircons in the Uivak I gneisses have ages between 3.73 and 3.86 Ga and are more likely to have been derived from a pre-existing high-grade metamorphic gneiss complex than from the Nulliak association. In the early Archaean there were probably several rapid cycles of sedimentary deposition and volcanism followed by emplacement of major plutons.
Mid Archaean gneisses are more abundant in northern Labrador than previously realised. The late Archaean metamorphic history of these gneisses is different from the history of the early Archaean gneisses. Whereas an important part of the mid Archaean suite was emplaced in granulite facies and retrogressed at the time of granitoid veining at ea. 2.99 Ga, the major part of the early Archaean rocks were reworked under granulite facies conditions in a sequence of closely spaced events between 2. 7 and 2.8 Ga. The two groups of gneisses had different metamorphic histories until ea. 2.7 Ga, but late and post-tectonic granites of 2.5- 2. 7 Ga age cut across both. It is suggested that the terrane model in southern West Greenland can be extended to Labrador and that tectonic intercalation of early and mid Archaean gneisses took place around 2.7 Ga. Correlation between the Maggo gneisses around Hopedale, mid Archaean gneisses in northernmost Labrador and gneisses from the Akia terrane in West Greenland is suggested. Like the Malene supracrustals in West Greenland the Upernavik supracrustals in Labrador are composite associations, the youngest of which are thought to have been deposited around 2. 7 Ga.
Post-kinematic diorite intrusions in Archaean basement rocks around outer Fiskefjord, southern West Greenland
Authors: Garde A. A.
Published: July 2021

About twenty small dioritic intrusions around outer Fiskefjord, southern West Greenland, which are undeformed and unmigmatised, mark the final stage in middle Archaean accretion of continental crust, deformation and high-grade metamorphism in the Akia terrane. The diorites were emplaced into hot tonalitic gneisses, some of which were thoroughly retrograded from granulite facies prior to diorite intrusion. The diorites are themselves sporadically retrograded. A conventional zircon U-Pb age of 3017 + 12/-10 Ma has been obtained from one of the diorites. The diorites have SiO2 contents between ea. 52 and 58 wt. % and up to ea. 15% MgO, and some of them border on leuconorite or anorthosite, with normative plagioclase contents up to ea. 85 wt. % . Trace element compositions are characterised by elevated amounts of Zn, Co, Ni, and especially Cr, but low contents of several LIL elements, and they were probably contaminated with sialic crust. The diorite intrusions may be related to a group of a more mafic intrusions with anomalous contents of precious metals, forming the "norite belt" some 50 km north of Fiskefjord.

On the issue of digitalization of labor relations: Theoretical and practical aspects
Authors: Potapova N. D. , Potapov A. V.
Published: July 2021

The article analyzes the problem of using digital technologies and the online space within the framework of labor law, based not only existing regulatory legal acts but also legislative drafts in the field of the digitalization of labor relations. Therewithal, the purpose of the study is to generalize current and future Russian legislation, to manifest the contradictions and gaps in the legislation, to evaluate laws and regulations from a practical point of view, and to elaborate proposals for their improvement. For this purpose, the authors take into account the existing experience gained in the course of experiments on the introduction of electronic document management by individual employers. The achievement of the research goals is ensured by the use of the formal legal method. First of all, the article draws attention to the tendency of expanding the differentiation of the labor regulation, caused by many factors, including the informatization of all social relations. It is concluded that the transition to an innovative, socially-oriented economy is impossible without a flexible labor market with new areas of employment, including employment through the use of information technology resources. Analyzing the practical aspects of electronic workflow, the article covers the theoretical aspect of the existence of the so-called “information legal relationship” in the subject of labor law. The analysis of the legislative drafts and the current legislation focuses on controversial wording and emphasizes that their incorrectness creates high risks of labor disputes. The authors insist that when introducing an electronic workflow, the parties should be provided with an alternative to the actions. The authors defend the view that it is necessary to clarify the scope of information transmitted by the employer to the Pension Fund of the Russian Federation when maintaining electronic employment record books with regard to the inclusion of information about employee awards in them. They also propose determining the procedures of the formation of human resources services in the Labor Code of the Russian Federation. As a final point, it is concluded that all the proposed initiatives are aimed at ensuring the tasks of the state for the introduction of digital technologies in all areas of social life, including in labor relations, and, ultimately, at achieving the optimal balance between the interests of the parties of the labor relations and the interests of the state, which is the main goal of labor legislation.

Az otthon egy olyan összetett fogalom, mely erősen támaszkodik a szubjektív élményekre és azok interpretációjára. Az otthon és az otthonérzet  kiemelt fontosággal bír a bevándorlók életében és a migrációs folyamatok során azzal együtt, hogy fokozatosan átértékelődik, újabb jelentéstartalmakkal is bővül. Az elmúlt harminc évben kínai bevándorlók hozták létre az egyik legjelentősebb diaszpórát Magyarországon. Hátrahagyva Kínát új otthonukat a fogadó ország társadalmának merőben eltérő kulturális közegében kellett megteremteniük. Kultúrák és országok között felnövekvő gyermekeik pedig ugyancsak egyedi otthonképet alakítottak ki maguknak. Ez a tanulmány 139 résztvevő bevonásával készült kutatás eredményeit mutatja be, melyen keresztül igyekszik feltárni, hogy hogyan alakul az eltérő migrációs háttérrel rendelkező kínai bevándorlók otthonképe és az otthon fogalmának megalkotása.

Possible pathophysiological mechanisms of the in-stent thrombosis following COVID-19 infection are discussed.
Heart failure with preserved ejection fraction – new elements of evidence in the field of pathophysiology and new treatment options
Authors: Kanazirev Branimir
Published: July 2021

Consistent with the understanding of the comorbidity-inﬂ ammation relationship, concomitant diseases and especially metabolic comorbidities are thought to stimulate the development and severity of heart failure with preserved ejection fraction through a cascade of mechanisms supporting systemic tissue inﬂ ammation leading to myocardial ﬁ brosis. Recently, new experimental and clinical evidence has emerged that enhances validity and veriﬁ es the inﬂ ammatory-proﬁ brotic paradigm. This evidence consists of: (1) myocardial inﬁ ltration with immunocompetent cells not only due to metabolic load caused by obesity but also due to arterial hypertension-induced haemodynamic loading of extracellular matrix components (such as basal laminatin interacting with basal laminate); (2) expression in cardiomyocytes of inducible nitric oxide synthetase under the inﬂ uence of circulating proinﬂ ammatory cytokines, which leads to accumulation of degraded proteins in the myocardium due to an unfolded protein response; (3) deﬁ ning phenogroups of patients with heart failure with preserved ejection fraction with a distinct inﬂ ammatory and proﬁ brotic component by machining algorithms; (4) direct association. in mediation analysis between comorbidities, inﬂ ammatory biomarkers and impaired myocardial structure and function with endothelial expression of adhesion molecules already accumulated in early preclinical heart failure with preserved ejection fraction (CH stage A, B). This new evidence paves the way for future treatment of heart failure with a conserved ejection fraction with biologics directed against 1) inﬂ ammatory cytokines, 2) stimulating the development of a complete protein response and non-accumulation of protein in the chiocardia by phosphodiesterase inhibitors 1) the rigidity of titin by natriuretic peptide – the particular guanylyl cyclase – PDE9 (phosphodiesterase 9) and 4) molecular and cellular regulatory mechanisms that control myocardial ﬁ brosis.

Published: July 2021

The cardiovascular diseases are one of the main causes of mortality in the countries of Europe and North America. The heart failure (HF) and diabetes mellitus (DM) are widely spread diseases that become more frequent with the population aging in those regions. The algorithm of HF treatment in the last two decades includes several new medications. The SGLT-2 inhibitors (dapagliﬂ ozin, empagliﬂ ozin and canagloﬂ ozin) are new class anti diabetic medications which have positive effect on cardiovascular complications in patients with and without DB. The main trials using those medications in this group of patients and the most probable mechanisms, responsible for their effects, are the topic of this review.

We study a kinetic-fluid model in a \begin{document}$ 3D $\end{document} bounded domain. More precisely, this model is a coupling of the Vlasov-Fokker-Planck equation with the local alignment force and the compressible Navier-Stokes equations with nonhomogeneous Dirichlet boundary condition. We prove the global existence of weak solutions to it for the isentropic fluid (adiabatic coefficient \begin{document}$ \gamma> 3/2 $\end{document}) and hence extend the existence result of Choi and Jung [Asymptotic analysis for a Vlasov-Fokker-Planck/Navier-Stokes system in a bounded domain, arXiv: 1912.13134v2], where the velocity of the fluid is supplemented with homogeneous Dirichlet boundary condition.

Let $ G $ be a finite group. A bipartite graph associated to elements and cosets of subgroups of $ G $ is the simple undirected graph $ \Gamma(G) $ with the vertex set $ V(\Gamma(G)) = A\cup B $, where $ A $ is the set of all elements of a group $ G $ and $ B $ is the set of all subgroups of a group $ G $ and two vertices $ x \in A $ and $ H \in B $ are adjacent if and only if $ xH = Hx $. In this article, several graph theoretical properties are investigated. Also, we obtain the diameter, girth, and the dominating number of $ \Gamma(G) $. We discuss the planarity and outer planarity for $ \Gamma(G) $. Finally, we prove that if $ p $ and $ q $ are distinct prime numbers and $ n = pq^k $, where $ p < q $ and $ k\geq 1 $, then $ \Gamma(D_{2n}) $ is not Hamiltonian.
Edge irregular reflexive labeling for the $ r $-th power of the path

Published: July 2021

Let $ G(V, E) $ be a graph, where $ V(G) $ is the vertex set and $ E(G) $ is the edge set. Let $ k $ be a natural number, a total k-labeling $ \varphi:V(G)\bigcup E(G)\rightarrow \{0, 1, 2, 3, ..., k\} $ is called an edge irregular reflexive $ k $-labeling if the vertices of $ G $ are labeled with the set of even numbers from $ \{0, 1, 2, 3, ..., k\} $ and the edges of $ G $ are labeled with numbers from $ \{1, 2, 3, ..., k\} $ in such a way for every two different edges $ xy $ and $ x^{'}y^{'} $ their weights $ \varphi(x)+\varphi(xy)+\varphi(y) $ and $ \varphi(x^{'})+\varphi(x^{'}y^{'})+\varphi(y^{'}) $ are distinct. The reflexive edge strength of $ G $, $ res(G) $, is defined as the minimum $ k $ for which $ G $ has an edge irregular reflexive $ k $-labeling. In this paper, we determine the exact value of the reflexive edge strength for the $ r $-th power of the path $ P_{n} $, where $ r\geq2 $, $ n\geq r+4 $.

Among various improvements in fuzzy set theory, a progressive development has been in process to investigate fuzzy analogues of fixed point theorems of the classical fixed point results. In this direction, taking the ideas of $ \theta $-contractions as well as Feng-Liu's approach into account, some new fuzzy fixed point results for nonlinear fuzzy set-valued $ \theta $-contractions in the framework of metric-like spaces are introduced in this paper without using the usual Pompeiu-Hausorff distance function. Our established concepts complement, unify and generalize a few important fuzzy and classical fixed point theorems in the corresponding literature. A handful of these special cases of our notions are pointed and analyzed. Some of the main results herein are further applied to derive their analogues in metric-like spaces endowed with partial ordering and binary relations. Comparisons and nontrivial examples are given to authenticate the hypotheses and significance of the obtained ideas.

The aim of this paper is to establish a representation formula for the solutions of the Lamé-Navier system in linear elasticity theory. We also study boundary value problems for such a system in a bounded domain $ \Omega\subset {\mathbb R}^3 $, allowing a very general geometric behavior of its boundary. Our method exploits the connections between this system and some classes of second order partial differential equations arising in Clifford analysis.

Aims

By associating features with orthonormal bases, we analyse the values of the extracted features for the daily biweekly growth rates of COVID-19 confirmed cases and deaths on national and continental levels.

Methods

By adopting the concept of Fourier coefficients, we analyse the inner products with respect to temporal and spatial frequencies on national and continental levels. The input data are the global time series data with 117 countries over 109 days on a national level; and 6 continents over 447 days on a continental level. Next, we calculate the Euclidean distance matrices and their average variabilities, which measure the average discrepancy between one feature vector and all others. Then we analyse the temporal and spatial variabilities on a national level. By calculating the temporal inner products on a continental level, we derive and analyse the similarities between the continents.

Results

On the national level, the daily biweekly growth rates bear higher similarities in the time dimension than the ones in the space dimension. Furthermore, there exists a strong concurrency between the features for biweekly growth rates of cases and deaths. As far as the trends of the features are concerned, the features are stabler on the continental level, and less predictive on the national level. In addition, there are very high similarities between all the continents, except Asia.

Conclusions

The features for daily biweekly growth rates of cases and deaths are extracted via orthonormal frequencies. By tracking the inner products for the input data and the orthonormal features, we could decompose the evolutionary results of COVID-19 into some fundamental frequencies. Though the frequency-based techniques are applied, the interpretation of the features should resort to other methods. By analysing the spectrum of the frequencies, we reveal hidden patterns of the COVID-19 pandemic. This would provide some preliminary research merits for further insightful investigations. It could also be used to predict future trends of daily biweekly growth rates of COVID-19 cases and deaths.

The use of cold-formed steel (CFS) channel sections with rectangular holes in the web is becoming gradually popular in building structures. However, such holes can result in sections becoming more susceptible to be distortional buckling and display lower load-carrying capacities. This paper presents a total of 44 axially-compressed tests of CFS lipped channel columns with and without rectangular web holes including different hole sizes and cross-sections. The test results show that the specimens were controlled by distortional buckling or interaction of local buckling and distortional buckling. The load-carrying capacities of specimens with rectangular holes were lower than that of specimens without hole. The load-carrying capacities of specimens were gradually decreased with the increasing of dimensions of holes. Then a nonlinear elasto-plastic finite element model (FEM) was developed and the analysis results showed good agreement with the test results. The validated FE model was used to conduct a parametric study involving 16 FEM to investigate the effects of the section, the dimension of the hole, and the number of holes on the ultimate strength of such channels. Furthermore, the formulas to predict the distortional buckling coefficient were developed for the section with holes by using the verified FEM. Finally, the tests and parametric study results were compared against the distortional buckling design strengths calculated in accordance with the developed method. The comparison results show that the proposed design method closely predict the load carrying capacity of CFS channel sections with rectangular web holes.

Everybody is at risk of being infected by drug-resistant microscopic organisms. Managing with sickness has never been less demanding within the history of our species. At the current rate of antimicrobial resistance (AMR) in microbes, specialists foresee that battling infections tuberculosis, HIV, and intestinal sickness will become more complicated. Antimicrobial resistance is rendering numerous life-saving drugs useless. Antibiotic-resistant microbes, known as “superbugs,” are getting to be more various and more harmful, thanks to the proceeding abuse of anti-microbials. Natural medication offers an alternative to these progressively ineffectual drugs. According to the World Health Organization (WHO), traditional medicine is a holistic term enclosing diverse health practices. Concurring to a report by the College of Maryland Therapeutic Center, turmeric's volatile oil serves as a common anti-microbial.

Muslim American high school seniors navigate their educational spaces at a time when the 2016 Election has unleashed a rhetoric that is riddled with Islamophobia. The experiences of four female participants engages us in their counter-narratives, debunking stereotypes and assumptions that exist about their demographic. The formal and informal experiences of the educational journeys of these participants help us explore the role of family, faith-based education, mosque, and community in the lives of these students. The social and academic learning opportunities for these participants showcased instances of inclusion and marginalization, where there were times when the students underwent a double consciousness. Transitioning from faith-based schools to the public education system became easier when positioned in a climate of diversity. Muslim American students experience a dichotomous pull between religious values and American culture and remain cognizant of these differences. Muslim educational leadership will find the study insightful.
Environmental Awareness

University studies for the architecture degree in Spain give very little weight to considerations related to the design of a healthy interior environment. The low number of subjects related to interior comfort criteria may cause the student to underestimate the importance of environmental design of closed spaces in favor of aesthetic or merely functional aspects. However, there is a direct relationship between formal design decisions and environmental conditions in buildings, and future architects must understand those connections in order to make designs that combine efficiency and high aesthetic value. In this chapter, several pedagogical strategies are presented to get architecture students to learn and internalize the link between design and interior conditions, aiming at the acquisition of an adequate environmental awareness.

For virtual reality (VR), augmented reality (AR), and mixed reality (MR) to become effective learning modalities, they must be considered in the context of experiential or constructivist learning which could disrupt traditional instructional and educational practices given their interactive quality. How might educators assess these applications and their implementation to determine their learning potential for online instruction? By applying the studio thinking framework (STF) and the presence pedagogy (P2) model, unique insights may be gained in terms of virtual reality's value to the learning process. Current research shows many similarities between the skills taught in studio art classes and opportunities to learn the same skills in virtual educational applications, while the P2 model has demonstrated its effectiveness in applying pedagogical strategies to collaborative VR environments. Tactics to prepare, apply, assess, and evaluate (PAAE) this technology in educational programs for teachers and school leaders provide a guide for implementation.

This study sought to contribute to the scholarly discourse of understanding how pre-service student teachers experienced evaluation via teacher performance assessments (TPAs). More specifically, this study sought to explore the experiences that pre-service teachers underwent to complete the Educative Teacher Performance Assessment (edTPA). Through extensive interviews and thematic data analysis, this research discerned what the informants' experiences were. Although informants experienced many benefits while completing their portfolios, three primary areas of struggle emerged from the data. First, informants struggled with interpreting and navigating the edTPA assessment handbook. Second, informants had problems adapting edTPA requirements to their teaching. Third, informants experienced problems with their concept of audience. As a result, the findings reported in this study have numerous implications that would prove beneficial to teacher educators, institutions of teacher training, policymakers, designers of assessments, and future and current educators.
