Published: July 2024

Relevance. Training a sense of distance in boxing, crucial for success in fights, proves challenging due to its complexity, closely tied to technical and tactical training. The relevance of the study is conditioned upon the need to find means and methods of sports training of boxers that will contribute to achieving high results in boxing. Purpose. The purpose of the study is to summarise the theoretical and methodological aspects of the development of a sense of distance among boxers of different qualifications. Methodology. To achieve the purpose, the following methods were used: analysis of theoretical works and empirical research, analysis, synthesis, interviews with trainers, questionnaires, modelling. Results. The study examined the development of a sense of distance in boxers of varying skill levels, taking into account their physical attributes, psychological traits, and fighting styles. Through interviews with 14 male trainers aged between 27 and 43, as well as a thorough review of theoretical literature, the research identified, isolated, and categorized the key features influencing distance perception in boxing. It was found that a boxer's proficiency in gauging distance significantly influences their tactical approach to a fight, with more talented or experienced boxers demonstrating a heightened sense of distance. Conclusions. The study underscores the lack of detailed research on the development of a boxer's sense of distance across various skill levels. Existing exercises are not tailored to individual boxers' qualifications, body types, or fighting styles. Trainers acknowledge the importance of distance perception but rely mainly on general training exercises. The findings of the study are expected to enhance overall training effectiveness by providing targeted strategies for cultivating distance awareness at each stage of a boxer's development. The results of the study have practical value for trainers, athletes, and sports theorists. Keywords: distance; boxing; qualification; training; coordination

Published: July 2024

Relevance. The relevance of the study lies in the fact that education cannot be limited only to mastering knowledge and professional skills in the chosen field and narrow specialisation. The existing foundations of graduate training aimed at deepening practice in one professional field are not enough. In such conditions, education should ensure that the students receive knowledge and skills that will give them a sense of satisfaction with learning. Purpose. The purpose of the study is to consider the theoretical and methodological foundations of humanisation education in higher educational institutions on the example of teaching chemistry. Methodology. The methodological framework encompassed several approaches to exploring this subject, including didactic, humanistic, general pedagogical, and pedagogical experiment methodologies. Results. The study on the theoretical and methodological foundations of humanisation education in universities, focusing on teaching chemistry, identified key outcomes. Firstly, the adoption of student-centric teaching methods, facilitated by the transition of teachers into organisers of the educational process, has enhanced student engagement and independent learning. Secondly, the expansion of educational content to include interdisciplinary perspectives alongside specialised subjects has provided students with a more comprehensive understanding of chemistry in real-world contexts. Lastly, the shift in attitudes and relationships between faculty and students has fostered a more supportive and collaborative learning environment. Conclusions. In conclusion, the findings underscore the importance of humanisation in higher education, particularly in the field of teaching chemistry. By prioritising student engagement, interdisciplinary learning, and supportive relationships, universities can create a more enriching educational experience. However, the implementation of humanisation strategies may encounter challenges, including the need for faculty adaptation and resource allocation. Nevertheless, the practical significance of these strategies in enhancing the quality of education in universities cannot be overstated, highlighting the importance of their effective implementation and continued exploration.

Improving VAT collection efficiency through policy design and compliance improvement and moderated by control of corruption
Authors: Wijaya Suparna , Bhuana Bhima Chandra
Published: July 2024

Value Added Tax (VAT) is increasingly relied upon by an increasing number of economies, as shown by the global trend of increasing standard tax rates, but raises questions about the efficiency of its levy. This study revisits the determinants of VAT collection efficiency by using the C-efficiency ratio approach. Using a dataset of countries in the SEAO region (East Asia, Southeast Asia, and the Pacific), this study was performed quantitatively using a panel data regression analysis. The results show that the government effectiveness index is unlikely to be an appropriate proxy for the compliance gap. In terms of the policy gap, policy changes by increasing the standard VAT rate might reduce the C-efficiency ratio, whereas lowering the VAT registration threshold might not improve the C-efficiency ratio. However, the control of corruption index as a moderating variable could antagonize the negative effect of the VAT standard rate on the C-efficiency ratio. This finding corroborates previous studies and encourages discussion to find variables that better measure compliance and policy gap.

Published: July 2024

This study aims to formulate and characterize zinc-loaded hydrogel infused with Aloe barbadensis mucilage for wound dressing. Five formulations containing varying proportions of carbopol, zinc, Aloe and water (as vehicle) were developed via physical crosslinking using triethanolamine. All formulations had a translucent off-white colour while the control gave a transparent gel. The viscosity was the highest in the control, 30000.00 ± 2.07 PaS. The pH of the formulations was between 5.7 and 5.8. formulation 2 which was composed of 30 mg of Zinc and 1.4 mg of Aloe barbadensis incorporated into 1% w/v Carbopol Ultrez hydrogel polymer had the lowest swelling index of 79.2 ± 1.95% implying that it had the fastest drug release rate. The wounds treated with formulation 2 had the most rapid healing with no sign of scars in the wound area. Histomorphometric evaluation reflected a high re-epithelisation rate of 70%, a significant percentage occupied by collagen in granulation tissue of 85%. The thickness of the tissue's central region was 10 mm. The inflammatory cells /mm2 tissue was 200 cells/mm2 while the number of microvessels in granulation tissue was 1.0 microvessels/mm2. Zinc-loaded hydrogel infused with Aloe barbadensis mucilage shows great potential as a modern wound dressing.

Authors: Bainbridge Joyce , Carbonaro Mike , Green Nicole
Published: July 2024

This article presents the findings of an online survey administered to Alberta elementary school teachers in 2000-2001. The survey explored the teachers’ knowledge and use of Canadian children’s literature and their thoughts about the role of Canadian literature in elementary school classrooms. Canadian children’s trade books espouse particular images and values that assist young Canadians in developing a sense of their national and personal identities. Respondents expressed their thoughts about the advantages and disadvantages of using Canadian literature. Overall, most teachers appeared to be unfamiliar with contemporary Canadian books and included Canadian materials in their classroom instruction only for specific Canadian content.
Contingent Conditions of Change: An Exploration of Feminist Theatre Practice
Authors: Twomey Sarah
Published: July 2024

This article explores how critical pedagogy and theatre arts can examine difference, change, and transformative possibilities in public spheres of educational practice. This narrative study offers a useful contribution on how theory, research, and practice can contribute to new ways of framing transformative feminist pedagogy in school cultures. I give an overview of critical pedagogy and the intersectionalities between concepts of liberatory pedagogy (Freire, 1970a) and the work of Brazilian theatre activist Augusto Boal (1979, 1992, 1995, 1998). I discuss how Boal’s philosophy and techniques of theatre of the oppressed can intersect in various ways with theatre arts curricula and feminist pedagogy. Using a case study of a young women’s theatre project Realtalk, I propose a postfeminist pedagogy and conditions for a form of radical education that offers a particular understanding of the complexities of how power is negotiated in schools across difference.
The Bookmark Procedure for Setting Cut-Scores and Finalizing Performance Standards: Strengths and Weaknesses
Authors: Lin Jie
Published: July 2024

The Bookmark standard-setting procedure was developed to address the perceived problems with the most popular method for setting cut-scores: the Angoff procedure (Angoff, 1971). The purposes of this article are to review the Bookmark procedure and evaluate it in terms of Berk’s (1986) criteria for evaluating cut-score setting methods. The strengths and weaknesses of the Bookmark are critically examined and discussed. In general, the strengths of the Bookmark method are that it (a) accommodates constructed-response as well as selected-response test items; (b) efficiently accommodates multiple cut-scores and multiple test forms; and (c) reduces cognitive complexity for panelists. Despite unresolved issues like the choice and understanding of the response probability, the Bookmark method remains a promising procedure for setting cut-scores and finalizing performance standards.
Contained Entity of an Educational Innovation: The Realities of Micropolitics
Authors: Raksit Mandira
Published: July 2024

This study was about a single case of educational innovation and excellence in educational technology in a secondary school in Ontario. The researcher explored the question of how the innovation resulted from an individual effort and attainment remained a “contained entity” after its decade-long existence. From the lenses of multiple realities, the researcher critically interpreted how micropolitics including gender and power dynamics and teacher resistance could create complexities for the institutionalization of the innovation. The district was urged to consider the lack of time and professional development issues raised by teachers. Further research was required to address the conspicuous absence of gender gap in this study.
The Development of an Emotional Response to Literature Measure: The Affective Response to Literature Survey
Authors: Fischer Ronald G. , Fischer Jerome M.
Published: July 2024

Based on theories of emotional intelligence, adult education, psychology of reading, and emotions and literature, this study was designed to develop and validate the Affective Response to Literature Survey (ARLS), a psychological instrument used to measure an emotional response to literature. Initially, 27 items were generated by a review of research relevant to emotional intelligence and emotional effects of literature. A panel of 10 experts rated 27 proposed items. After applying the content validity ratio to the expert’s ratings, 18 items were retained. The instrument was then administered to 165 individuals to assess psychometric properties. The ARLS demonstrated high internal consistency (Cronbach’s alpha=.90) and test-retest reliability (r=.90, p < .001). Factor analysis extracted four factors: (a) Reflective Synthesis, (b) Acting with Volition, (c) Processing, and (d) Empathetic Responding. The four factors have important implications for conducting research sensitive to literature, emotional intelligence, and transformational learning.
Cooperative Learning: Group Processing and Students Needs for Self-Worth and Belonging
Authors: Strahm Muriel F.
Published: July 2024

The purpose of this study was to examine students’ perceptions of the extent to which reflection, a principle of cooperative learning, satisfied their needs for self-worth and belonging. Eight mature preuniversity students completed a scaled questionnaire and took part in a focus group interview following a 12-week preliminary study into the efficacy of reflection. Students perceived reflection as contributing to the satisfaction of their needs for self-worth and belonging. They also perceived reflection as contributing to their needs for acceptance. This was unexpected and is perhaps critical, as acceptance might be a condition of effective learning. Hence this article calls for further research into reflection in relation to acceptance and the role these play in contributing to effective learning and teaching.
Analogies, Metaphors, and Similes for HIV/AIDS Among Ugandan Grade 11 Students
Authors: Mutonyi Harriet
Published: July 2024

This article looks at the importance of student-generated analogies, metaphors, and similes as an entry point into their understandings of HIV/AIDS. In addition, it argues that analogies, metaphors, and similes are good tools for eliciting students’ prior understandings of HIV/AIDS, especially matters relating to sexuality that are often figuratively communicated in many Ugandan cultures. It posits that students’ prior knowledge determines how they respond to messages about HIV/AIDS. The article suggests that in order to prevent vulnerability to HIV/AIDS among Ugandan youth, learning should be viewed as a process of conceptual change so that students become active participants in their own learning process.
Psychoanalytic Implications for the “Consulting Cure”
Authors: Wallin Jason
Published: July 2024

From October 2004 to June 2006, I worked as a curriculum leader across 18 elementary schools as part of an Alberta Incentive for School Improvement project focused on the reform question: How does inquiry transform learning environments? As a curriculum leader, my role included, but was not limited to, the introduction, articulation, and development of the project’s main tenets and goals among the teaching staffs of participating schools. In support of professional development, I worked closely with teachers in discussing, planning, and co-teaching from an inquiry-based perspective. As I developed close relationships with teacher practitioners, my position acted as a catalyst for pedagogical change in the classroom and supported broader institutional reform.
Ghost Red Blood Cells For Enhanced Particle Detection With Defocusing PTV In Microcirculation Experiments

Published: July 2024

Particle tracking of rigid fluorescent particles in microcirculation environments is often found to be difficult, since the presence of red blood cells (RBCs) at physiologically relevant conditions (i.e., hematocrit) masks the particle images. In turn, making particle detection challenging. To overcome this difficulty, we propose to use ghost RBCs for enhanced particle detection. These are quasi-transparent RBCs obtained by removing the hemoglobin from normal RBCs. To understand whether the ghost RBCs can improve the particle detection, we performed defocusing particle tracking measurements with the general defocusing particle tracking (GDPT) method of the rigid fluorescent particles in normal and ghost RBC flows. The measurements were performed at physiological relevant hematocrit and for three different flow rates. From the three-dimensional particle trajectories, we evaluated the correlation coefficient from the GDPT evaluations and compared the fluid dynamic behavior of the two types of cells. Overall, the results show that ghost RBCs are an attractive solution for this type of experiments, since they improve the correlation coefficients up to values similar to cell-free experiments, while exhibiting a fluid dynamic behavior similar to normal RBCs i.e., in terms of velocity and relative viscosity data.
Coupling Coherent Point Drift And Affine Least-Squares Transformation To Build Trajectories In TR-PTV
Authors: Thomas Lionel , Mercier Bertrand , Tremblais Benoit , David Laurent
Published: July 2024

The robustness and accuracy of state-of-the-art time-resolved Particle Tracking Velocimetry algorithms is strongly supported by the use of the temporal coherence of particle trajectories. However, to exploit this coherence, the particle needs to be tracked for a sufficiently long period. This condition cannot be achieved if the time of flight of the particles across the measurement volume is not long enough, for example because the limited illumination energy requires the thickness of the volume to be thin. The authors propose to address this difficulty by providing an algorithm based on the spatial coherence of the trajectories rather than the temporal one. This algorithm results from the coupling of two methods; the Coherent Point Drift (CPD), which has proven to be accurate in pairing particles from two instants, but with an insufficient recall for time-resolved application, and the Affine Least Square Transformation (ALST), which allows transporting particles that were missed by the CPD. This algorithm is integrated into a global process that includes an Iterative Particle Reconstruction (IPR) algorithm to extract a list of particles from the images. First tests performed on a synthetic test case consisting of images of particles advected by a turbulent flow highlighted the potential of the method for tracking short tracks. With six frames, the recall is found to be 99.6% with the present method against 98.3% with the DaVis 10.2 implementation of ShakeThe-Box (STB). However, the error is much larger with a false positive rate of 5.1% with our method but only 0.2% with (STB). The cause of this high error rate is analysed and it is speculated that it is partly explained by the tendency of the IPR to detect the same real particle multiple times, which is a concern that has to be addressed in future work.
A Meshless And Binless Approach To Compute Statistics In 3D Ensemble PTV
Authors: Ratz Manuel , Mendez Miguel Alfonso
Published: July 2024

We propose a method to obtain super-resolution of turbulent statistics for three-dimensional ensemble particle tracking velocimetry (EPTV). Our approach is “meshless” because it does not require a grid to compute derivatives, and it is “binless” because it does not require bins to compute local statistics. The method combines the constrained radial basis function (RBF) formalism introduced in Sperotto et al. (Meas Sci Technol, 33:094005, 2022) with a kernel estimate approach for the ensemble average of the RBF regressions. The computational cost for the RBF regression is alleviated with the partition of unity method (PUM). We compare the newly proposed method with traditional binning-based approaches such as Gaussian weighting (Agüí and Jiménez, JFM, 185:447-468, 1987) and local polynomial fitting (Agüera et al, Meas Sci Technol, 27:124011, 2016). The results on experimental data of an underwater jet show a better resolution of spatial gradients of turbulent stresses while at the same time yielding an analytical expression which results in super-resolution of statistical quantities.

The leading cause of mortality and morbidity globally is cardiovascular disease (CVD). CVD can present in the thoracic aorta as atherosclerosis, an aneurysm or a dissection, which can be related to certain fluid mechanics metrics. This study investigates the fluid flow profiles within a healthy and a branched endovascular graft-treated rigid phantom, manufactured from Sylgard 184, to determine the effect geometry has on the resulting fluid mechanics and the subsequent biological processes. Planar particle image velocimetry data was recorded to visualise steady flow conditions at Reynolds numbers 4500 (peak), 3400 (mean), and −225 (reverse). Evaluation of anatomical features affecting the flow fields, concluded that the tapering of the healthy thoracic aorta naturally aids in the prevention of low flow on the inner arch wall more effectively than the untapered graft-treated model. Focus on the aortic branches demonstrated the angle of the aortic branches in relation to the aortic arch, highly affects the regions of low and high blood flow present within each branch. However, due to the biological response (or lack of) associated with a cellular boundary and synthetic material, the haemodynamic changes in the aortic arch and branches have different challenges. Therefore, direct replication of a healthy geometry is not necessarily optimal for the design of an endovascular graft.

Một số trường hợp bệnh nhân động kinh cục bộ không đáp ứng với điều trị bằng thuốc thì việc phẫu thuật có thể mang lại nhiều lợi ích. Hình ảnh cắt lớp phát xạ positron (positron emission tomography - PET) với thuốc phóng xạ 18F-Fluorodeoxyglucose (FDG PET) đánh giá chuyển hóa glucose của não là một kỹ thuật đã được ứng dụng rộng rãi trong việc đánh giá trước phẫu thuật ở những bệnh nhân động kinh kháng trị mà có hình ảnh cộng hưởng từ và điện não đồ không tương hợp trong việc xác định vùng sinh động kinh. FDG PET giúp phát hiện vùng sinh động kinh, phân vùng động kinh, giúp xác định mức độ lan rộng của vùng sinh động kinh. FDG PET còn cung cấp thêm thông tin quan trọng về tình trạng chức năng của phần còn lại của não. Ngoài ra, các đặc điểm chuyển hóa trên hình PET cũng góp phần tiên lượng hiểu quả phẫu thuật. Ghi hình PET thường được thực hiện ngoài cơn. Sử dụng hình ảnh MRI chụp trước đó hòa trộn với hình PET để xác định vị trí giải phẫu. Bài báo cáo này nhằm giới thiệu quy trình ghi hình FDG PET não, cách phân tích hình ảnh và vai trò của FDG PET trong đánh giá trước phẫu thuật động kinh trong điều kiện nguồn lực còn hạn chế ở Việt Nam.

Kerentanan, Perempuan, dan Kemiskinan? Menata Ulang Arah Pembangunan Perlindungan Sosial Netral Gender Menuju Inklusivitas Sosial di Kabupaten Batang
Authors: Setiawan Hendy
Published: July 2024

Tujuan tulisan ini mendiskusikan tentang pembangunan perlindungan sosial netral gender (P2SNG) di Kabupaten Batang. Sistem perlindungan sosial yang mengakomodasi kelompok perempuan rentan merupakan salah satu bentuk keberhasilan perlindungan sosial. Perlindungan sosial netral gender akan lebih akomodatif terhadap pemahaman kontruksi gender. Pada akhirnya akan melahirkan sistem yang sensitif gender. Kabupaten Batang sendiri sampai hari ini sektor kerentanan perempuan masih belum banyak diakomodasi. Maraknya persoalan sosial kemiskinan ekstrim, tingginya isu stunting, rendahnya indeks pembangunan gender, tingginya angka perceraian, serta maraknya angka kekerasan terhadap perempuan menunjukkan bahwa sistem perlindungan sosial sangat dibutuhkan bagi mereka. Hal tersebut dikarenakan dari semua masalah yang ada, pasti akan selalu melibatkan perempuan dalam pusaran tersebut. Sementara di saat yang sama implikasi kesetaraan gender yang diwacanakan ialah kesetaraan perempuan dan laki-laki. Tentu dalam konsep perlindungan sosial netral gender, harus dilihat bahwa laki-laki dan perempuan tidaklah sama. Oleh karena itu penelitian ini menjadi menarik untuk didiskusikan. Metode penelitian ini menggunakan pendekatan kualitatif dengan studi literature. Data didapatkan melalui observasi lapangan, pengumpulan sumber data informasi melui media, jurnal, berita, media masa, buku, laporan, atau dokumen laiinya yang berasal dari instansi formal. Data kemudian diolah sesuai dengan kebutuhan yang relevan. Kemudian data informasi dilakukan teknik analisis melalui pengumpulan data, reduksi, hingga penarikan kesimpulan. Hasil penelitian menunjukkan bahwa P2SNG belum sepenuhnya dikembangkan di Kabupaten Batang. Hal tersebut bisa diurai dari sistem perlindungan sosial di Kabupaten Batang yang tidak aomodatif dan menjangkau ke semua lini kelompok perempuan rentan. Oleh karena itu konsep perlindungan sosial netral gender menjadi hal yang perlu dipertimbangkan ke depannya.
