Local null controllability of the penalized Boussinesq system with a reduced number of controls
Authors: Bárcena-Petisco Jon Asier , Balc'h Kévin Le
Published: July 2021

In this paper we consider the Boussinesq system with homogeneous Dirichlet boundary conditions, defined in a regular domain \begin{document}$ \Omega\subset\mathbb R^N $\end{document} for \begin{document}$ N = 2 $\end{document} and \begin{document}$ N = 3 $\end{document}. The incompressibility condition of the fluid is replaced by its approximation by penalization with a small parameter \begin{document}$ \varepsilon > 0 $\end{document}. We prove that our system is locally null controllable using a control with a restricted number of components, localized in an open set \begin{document}$ \omega $\end{document} contained in \begin{document}$ \Omega $\end{document}. We also show that the control cost is bounded uniformly with respect to \begin{document}$ \varepsilon \rightarrow 0 $\end{document}. The proof is based on a linearization argument. The null controllability of the linearized system is obtained by proving a new Carleman estimate for the adjoint system. This inequality is derived by exploiting the coercivity of some second order differential operator involving crossed derivatives.

Authors: Lee Diane C. , Gefen David
Published: July 2021

As a safety-net medical center that serves many underserved communities, Einstein Medical Center Philadelphia (EMCP) faces many challenges in providing healthcare to its communities. To improve those services, EMCP has released a new IT healthcare portal (app). This chapter describes some of the promises and challenges EMCP is currently facing in their attempts to convince communities in its catchment area to adopt that healthcare portal. The challenges are discussed in the contexts of poor social determinants of health (SDOH), unique social factors, as well as the importance of managing community trust in EMCP within the broader contexts of underserved communities of which the new portal is only part of the story. This is not a typical case of IT adoption. The challenges at hand are not only technical but to a large degree social, dealing in part with issues of cultural diversity, perceived lack of respect, and poor health literacy.
The Wheel of Competencies to Enhance Student-Teacher Role Awareness in Teaching-Learning Processes
Authors: Rodrigues Flávia Pires
Published: July 2021

In this chapter, the wheel of competencies was used for enhancing educators and students' mutual awareness within the teaching-learning processes. This chapter described how teachers could use this tool in their opening class to build rapport and confidence as future teachers in higher education. The competencies reported are from a post-graduate discipline for students in Dentistry and Veterinary at the UNIP-Paulista University of São Paulo in Brazil, named “Higher Education Teaching Skills,” as a mandatory part of their curriculum. The coaching approach applied in this discipline included reflective questions, discussions in groups, plenaries, and the wheel of competencies. The idea is to make the students aware of coaching tools associated with blended learning, which is the teaching-learning philosophy of the discipline. At the closing class, the students can build an action plan as a student or as a future teacher. Throughout the year, it is essential to follow these competencies to improve the students' confidence.

These factors include student academic performance, attendance, individual view of future outlook, observation of student learned soft skills as a result of esports, as well as the sense of involvement on campus. According to the National Federation of State High School Associations, esports helps build a sense of community, aids in character development, and helps increase participation and engagement for students; furthermore, esports also allows for opportunities to explore STEM-related fields (NFHS Parent's Guide). As this is a major cause for the support of esports in education, the research aims to explore these concepts and its validity through individual students.
Tensions of Growth in Collegiate Esports
Authors: Bailon Mark Ryan , Holden Christopher L.
Published: July 2021

Looking at collegiate esports, the space is filled with a diverse array of programs growing at different rates and all finding legitimacy and recognition in different ways. However, many programs are faced with a specific tension between the flexibility of a grassroots club and the rigidity of university organization. This chapter will look at one particular program at the University of New Mexico and how it has been navigating its own identity as an affinity space and how its growth into something more may have unintended consequences that should be considered for any similar program. Specifically, the chapter will focus on what it means to be an affinity space, how UNM esports fits into that category, and what gets lost when attempting to integrate with different institutional-level structures.

Developing Scholarly Dispositions While Becoming a Participatory Action Researcher
Authors: Rose Crystal Dail
Published: July 2021

Participatory action research can be difficult to enact, especially as a novice researcher. The tensions between remaining true to the heart of PAR while also reconceptualizing her own identity as a student, novice, teacher, scholar proved challenging. This feat was accomplished with a thorough understanding of participatory action research; the scholarly dispositions needed to engage in this work; and the guidance, support, and careful questioning of a dissertation chair and committee. This chapter includes an overview of the methodology, participatory action research with photovoice; the possibility of unique scholarly dispositions needed by doctoral candidates interested in action-oriented methodologies; the author's own dissertation experiences; and concludes with lessons learned throughout the dissertation. Although a framework for the scholarly dispositions specifically for action-oriented methodologies is yet to be determined, the dissertation journey shared in this chapter could be a launching point for such work to occur.
Seeking Diversity in Children's Literature Utilized in Elementary Classrooms
Authors: Sableski Mary-Kate , Arnold Jackie Marshall
Published: July 2021

Utilizing literature in classrooms that is representative of all provides opportunities for students to find within a book the truth of their own experiences. Literature provides the windows, mirrors, and sliding glass doors that afford opportunities to consider multiple perspectives and lenses in life. This chapter discusses different representations of diverse literature in classrooms and explores what educators might consider for their teaching and learning. Specifically, the chapter describes books student teachers identify using in their classrooms and considers how the books aligned with the different categories of a rubric used to assess them. Of the 113 books sampled, only nine books distinctly represented diversity. Implications of these findings and how they can support and challenge the children's literature utilized in today's classrooms are discussed.
Skippyjon, Spanglish, and Stereotypes
Authors: Rodríguez Noreen Naseem , Updegraff Amy , Winters Leslie Ann
Published: July 2021

This case study engages Latinx Critical Race Theory to explore how a course on bilingualism, bilingual education, and Latinx youth in a Midwestern teacher preparation program developed preservice teachers' critical race and cultural consciousness. Through an emphasis on English hegemony and centering Latinx voices, the preservice teachers began to develop a critical consciousness around the interconnectedness of culture and language and were able to understand Skippyjon Jones as an example of what not to choose when critically selecting Latinx children's literature. They became increasingly adept at identifying and disrupting stereotypes and discerning more culturally authentic and sustaining pedagogical choices.
Up Close and Personal
Authors: Kimmel Sue C.
Published: July 2021

Preparing diverse students to become lifetime readers and writers is best facilitated through experiences with high quality, diverse literature and through the models of the authors and illustrators who create those works. Nothing quite brings an author or illustrator to life like hearing from them in person by hosting an author visit. This chapter explores the value of planning an author visit as an authentic means to learn about diverse authors and their work. Information is provided about identifying and choosing a diverse author or illustrator, planning the logistics of the visit, and preparing to build background and interest within the school and the community in anticipation of the visit. This information is framed with the elements for an assignment that could be employed in a children's literature course offered to pre-service teachers and librarians to create a mock plan for an in-person author visit in a school. Students could carry this assignment forward to their classrooms or libraries to plan an author visit or to write a grant to fund a visit.
Fostering Inclusive Communities Through Children's Literature
Authors: Murray-Everett Natasha C. , Schroeder Stephanie
Published: July 2021

This comparative case study explored pre-service teachers' (PSTs) understandings and concerns around creating inclusive classrooms before and after engaging in explicit instruction and practice surrounding issues of inclusion in elementary social studies methods. Findings illustrate that PSTs understood inclusion as an expansive concept, encapsulating various social identities, before and after explicit instruction. Engaging in a lesson planning project involving children's literature and a deep dive into anti-bias and inclusion literature helped to lessen concerns held by PSTs about creating inclusive classrooms but amplified other concerns, such as how to manage parental pushback and how to support students of marginalized backgrounds. This chapter addresses implications for elementary social studies teacher educators, such as the need to provide explicit practice and guidance when emphasizing the need for inclusive classroom communities, and the authors suggest ways PSTs' concerns could be lessened through interviews with parents and panel discussions with inclusive educators.

Engagement in Emergency Remote Education
Authors: García-Pastor María Dolores
Published: July 2021

Digital storytelling (DST) has been effective for student engagement in second language (L2) education. Yet, its impact on engagement has commonly been examined in the classroom through synchronous DST tools and platforms. This study enquires whether DST can be equally engaging in the context of emergency remote education caused by the COVID-19 pandemic. The participants of the study are 42 student-teachers of English who developed an asynchronous online DST project. Data were collected through a DST questionnaire and were analysed using quantitative and qualitative data analysis methods. DST was found to generate mainly cognitive engagement through self-reflection processes and behavioural engagement in the form of effort and time invested in the speaking and writing parts of the project. Emotional engagement was less frequent and emerged through positive emotions. Insufficient technology skills, the wrong timing and duration of the project, negative emotion arousal, and the absence of teacher and peer feedback and support appeared as potentially disengaging factors.

Authors: Bast Felix
Published: July 2021

India is the second-most populous country in the world. There had been a tremendous shift towards online learning through the Indian government's digital initiatives in general, and during COVID-19 lockdown in particular. An online self-report survey (n = 1318) was conducted to assess students' perception of online learning in this changed situation in comparison with traditional classroom learning. The study analysed eight independent variables on student perception towards online learning (e.g., gender, nature of the settlement, economic background, religiosity, primary electronic device, technology-receptiveness, age, and educational institution), with each of these variables forming respective research hypotheses. Results revealed several exciting facets of student perceptions. Receptiveness towards online learning was significantly higher for students from urban areas compared with rural areas. Possible reasons for these results are discussed, and the findings are contextualized in a broader perspective.
Developing Social Empathy With Higher Education
Authors: Olt Phillip A.
Published: July 2021

The purposes of this chapter are to demonstrate the need for social empathy in a democratic society, identify polarization barriers, and explore how American higher education can be a leading agent for developing social empathy. The United States has seen a recent rise in political tribalism, and it now faces rising antipathy between those holding polarized perspectives. Higher education is uniquely situated to address these problems. Like a mixing bowl, college is a place where students of all backgrounds can be combined in deep discourse at a key point in their psychological development. However, higher education has struggled to fulfill its potential, as efforts toward diversity have rarely achieved their goals. Utilizing the concepts of social empathy and honest diversity, a new approach to diversity work in higher education may hold the key to establishing the sector's prominence in developing a society of diverse people who can function respectfully toward one another.

In this regard, educational institutions are focusing to reduce the attainment gap between good, average, and poor performing students. Two different datasets are taken for this study. Students' data is collected through questionnaire, and Dataset 1 (D1) is created. The second dataset (D2) is taken from the repository. Both the datasets have been preprocessed followed by attribute selection and predictive modeling. In this study, predictive models have been built, and the learners are classified as high, average, and low performers based on their academic scores as well as on their demographic characters. The three classifier models are applied on the datasets. Based on the evaluation measures, the best classifier is identified. This early identification of low performance students will help the educators as well as the learners to put a special care to enhance the learning process as well as to improve the academic performance.
Optimal Cloud Service Provider Selection Based on QoS Metrics
Authors: Arunambika T.  , Senthil Vadivu P.
Published: July 2021

There are thousands of providers obtainable in the market, and more and more are being added to the service list every day. All of these providers claim that the services given to them are distinctive and hassle-free. To check their claim, the cloud service broker (CSB) verifies the quality of service (QoS) of the cloud service providers (CSPs) and the level of user needs. Depending on the requirements of the cloud consumer (CC), CSB allocates a CSP to it. This paper proposed optimal cloud service provider selection (OCSPS) based on QoS metrics. The CC would handovers the demand to the CSB for optimal CSP selection using QoS. Once the CSP selection process is complete, the outcomes would become back to the CC. Entire demands created to CCs are saved in the request buffer (RB) in the CSB. When a specific request is fulfilled, the subsequent demand would take from this RB. The experimental result shows that the proposed OCSPS algorithm takes less time for CSP ranking and optimal CSP selection.

The Influence of Finely Ground Limestone in the Design of Concrete for White Boxes Regarding the Suppression of Shrinkage
Authors: Osuská Lucia , Merunka Milan , Hela Rudolf
Published: July 2021

For concrete constructions built as underground spaces, basements or cellars, it is necessary for these constructions to be able to resist the influence of groundwater pressure that could disrupt the compactness of the entire construction by its action. For this reason, constructions of so-called white boxes are often used. White boxes are concrete constructions whose main capability is high water impermeability, exhibiting at the same time minimal volume changes. These properties could be accomplished by a series of several technological precautions, one of which is the composition of the concrete mixture itself. The aim of this paper is to evaluate the influence of finely ground limestone and the latent hydraulic addition of finely ground blast furnace slag on the properties of concrete composite such as water impermeability, water absorption, or volume changes. These properties are vital for the construction of white boxes. In this paper, the suitability of the mutual combination of active and internal additive will also be evaluated.

Evaluation on Microstructure Stability and Thermal Resistant Ability at High Temperature of Ternary-Blended Geopolymer
Authors: Nguyen Hoc Thang
Published: July 2021

Stability of microstructure and heat resistant ability at high temperature is one of the important properties in ceramics or silicate materials which are normally exposed with fire such as refractories and insulation or other materials used in furnaces. This study used a ternary-blended geopolymer which was synthesized from an optimized mixture of red mud (RM), rice husk ash (RHA), diatomaceous earth (DE), and water glass solution (WGS) with silica modulus of 2.5. The geopolymer samples were tested thermal properties of heat resistance (%), volumetric shrinkage (%), mass loss (%) at 1000°C to evaluate thermal resistant ability. Changes of microstructure of the ternary-blended geopolymer samples were also characterized before and after exposed at high temperature using methods of X-ray diffraction (XRD), Thermogravimetric analysis or thermal gravimetric analysis (DTA-TGA), and Scanning electron microscope (SEM). The experimental results showed the ternary-blended geopolymer has high thermal stability and unchanged microstructure even at high temperatures. Hence, the geopolymer in this study is suggested to apply as an insolation with the upper limit of temperature to work at 1000°C.

Authors: Skripkiūnas Gintautas , Karpova Ekaterina , Drochytka Rostislav , Hodul Jakub
Published: July 2021

Hydration of cement systems modified by nano additives requires the understanding of its mechanisms. The present research is focused on the investigation of hydration processes in cement pastes modified by multi-walled carbon nanotubes (MWCNTs) suspension. The ultrasonication method was used for homogenization of MWCNTs in the volume of an aqueous suspension. The hydration of cement pastes was assessed by the calorimetry test. The prolongation of cement hydration in case of modification by MWCNT suspension was observed. The microstructure observation by scanning electron microscopy (SEM) was performed for identification of MWCNT's dispergation in hardened cement pastes and for the observation of cement hydration products. The compressive and flexural strength were tested to evaluate the effect of MWCNT on mechanical properties of hardened cement paste.

Published: July 2021

Introduction: Dengue is one of the hyperendemic diseases in Sri Lanka with high morbidity and mortality. This study was aimed to assess knowledge, attitudes and practices of group of parents on pre-hospital management of fever in their children. Methods: A cross-sectional study was conducted incorporating either one of the parents of 86 children with fever admitted to two paediatric units in Teaching Hospital Karapitiya and District General Hospital, Matara over two months during a dengue epidemic. A self -administered pretested questionnaire with demographic data and questions to assess knowledge, attitudes and practices regarding pre-hospital management of dengue was used. Results: There were 81 (94.2%) females. The majority (69.76%) had educated beyond GCE O/L. Only 27.9% knew that they have a risk of dengue. The majority (66.28%) had excluded dengue due to the presence of respiratory symptoms. More than half of the parents (55.81%) knew that treatment with NSAIDs could aggravate dengue but 32.56% preferred NSAIDs, due to misconception of pyrexia related cerebral injury. A large majority (89.53%) knew proper hydration is needed and had hydrated their children. However, only 33.72% knew that hospital admission is needed if fluid intake is inadequate and only 19.77% knew that hospitalisation is needed if urine output is low. Only 30.23% knew that full blood count (FBC) should be done on day 3 of illness and 45.34% of the participants had got it done before admission. The majority (65.1%) knew dengue NS1 antigen test and out of them 75% had got it done before hospitalisation. Conclusions: Despite living in an endemic area, only a few parents knew that their children were at a risk of contracting dengue. Inadequate knowledge about the symptoms, when to hospitalize and misconceptions on treatment of fever were highlighted. Therefore, educating the parents on specific facts is effective.

While fever is a well-described precipitating factor of moyamoya-specific symptoms, moyamoya angiopathy (MMA) mimicking recurrent febrile seizures has never been reported before. Here, we report a case of MMA in a 4-year-old child who was misdiagnosed as simple febrile seizures on multiple occasions. This case underscores the importance of identifying early clinicoradiological clues of MMA for earlier diagnosis and better prognosis.

The ongoing coronavirus disease-2019 (COVID-19) pandemic has accounted for massive socioeconomic disruptions on the global scale and the number of cases and attributed deaths continue to rise. As the outbreak continues to expand in various nations, it indeed creates an opportunity for the policy makers to have a re-look on the national response to the outbreak. The proposed intra-action review can be scheduled whenever the policy makers feel that there is a need to update the existing emergency response strategies. In conclusion, the COVID-19 pandemic has made the health stakeholders and welfare agencies realize the gaps which are prevailing in the preparedness and emergency response. The conduction of periodic reviews at national or subnational level is the most appropriate approach to give an insight to the policy makers about the best interventions and those interventions which need to be re-visited for ensuring effective containment of the infection.

В работе изучается величина типа дискрепанса - дискрепанс с фиксированным объемом - множеств типа Коробова в единичном кубе. Недавно было обнаружено, что эта новая величина позволяет получать оптимальную по порядку скорость убывания для дисперсии.
Это наблюдение побуждает нас тщательно изучать эту новую версию дискрепанса, которая кажется интересной сама по себе. Работа развивает недавние исследования В. Н. Темлякова и М. Улльриха о дискрепансе с фиксированным объемом множеств Фибоначчи.

The Role of Trust in the Pattern of Enrollment to a Social Health Insurance Scheme and Distribution of Healthcare Facilities in Ibadan, Southwest Nigeria
Authors: Adewole David A. , Reid Steve , Oni Tolu
Published: July 2021

The National Health Insurance Scheme (NHIS) of Nigeria established in the year 2005 aims to minimize the inequity of access to quality healthcare services in Nigeria. As of the year 2017, enrollment in NHIS-accredited facilities in the southwest region of Nigeria was significantly clustered, with more than three-quarters of NHIS enrollees registered with only 10% of the available NHIS-accredited facilities in the six states of the region. This study explored the factors associated with the skewed distribution of enrollees across facilities and the influence of stakeholders. This is a descriptive, qualitative, case study design among stakeholders of the NHIS in Ibadan, Oyo State, Southwest, Nigeria. In-depth interviews were conducted between March and June, 2019, with all selected individual stakeholders as listed earlier. Data analysis was done using an inductive thematic approach. Across the board, there was a low level of trust in government and government policies among healthcare providers and enrollees. Few healthcare providers were willing to render services under the scheme at inception. The majority of the enrollees were compelled to register with the few available healthcare providers. Among the enrollees, a few personally chose healthcare facilities and providers that were perceived to render better quality services to receive care. Priority should be given to building trust among stakeholders in the NHIS as this would facilitate cooperation and better working relationship, and reposition the scheme for better performance.

Rapid and accurate diagnosis of visceral leishmaniasis (VL) is needed to initiate prompt treatment to reduce morbidity and mortality. Here, we evaluated the performance of loop-mediated isothermal amplification (LAMP) assay for the diagnosis of VL from blood in an endemic area in Ethiopia. LAMP was positive in 117/122 confirmed VL cases and negative in 149/152 controls, resulting in a sensitivity of 95.9% (95% CI: 90.69–98.66) and a specificity of 98.0% (95% CI: 94.34–99.59), respectively. The sensitivity of the LAMP assay was 95.0% (95% CI: 88.61–98.34) in HIV-negatives and 100% (95% CI: 85.18–100.0) in HIV-positives. Compared with microscopy, LAMP detected 82/87 (94.3%, 95% CI: 87.10–98.11) of the microscopy+ cases and was negative in 11/27 (40.7%, 95% CI: 22.39–61.20) of the microscopy− cases. Compared with the rK39 serology, LAMP detected 113/120 (94.2%, 95% CI: 88.35–97.62) of the rK39+ cases and was negative in 149/154 (96.8%, 95% CI: 92.59–98.94) of the rK39− cases. However, when compared with microscopy only, rK39 detected 83/87 (95.4%, 95% CI: 88.64–98.73) of the microscopy+ cases and negative in only 12/27 (44.4%, 95% CI: 25.48–64.67) of the microscopy– cases. There was an excellent agreement between rK39 and LAMP (Kappa = 0.91, 95% CI: 0.86–0.96). Furthermore, an algorithm using rK39 followed by LAMP would yield a sensitivity of 99.2% (95%CI: 95.52–99.89) and a specificity of 98.0% (95% CI: 94.34–99.59). The findings demonstrate that LAMP assay is an accurate and rapid molecular assay for VL diagnosis, including in HIV-1 coinfected patients, in an endemic setting.

Abstract— License plate is the unique identity of the vehicle, which serves as proof of the legitimacy of the operation of the vehicle in the form of a plate or other material with certain specifications issued by the police and contains the area code, registration number and validity period and installed on the vehicle. License plates are often used in automated parking systems and vehicle identification in case of traffic violations. So, it is necessary to build a system for detection and identification of license plates. The proposed license plate detection and identification system is divided into three main processes, namely license plate detection, character segmentation, and character recognition. The detection process uses transfer learning techniques using Faster R-CNN Inception V2. The segmentation process uses traditional computer vision with morphological operations and contours extraction. Then the character recognition process uses the MobileNet V2 transfer learning technique as an architecture for character classification. The recognition accuracy compared between MobileNet V2 and TesseractOCR shows that MobileNet V2 is superior with an accuracy rate of 96%, while Tesseract-OCR has a poor accuracy of 59%.
