GeoGebra Augmented Reality to Facilitate the Manipulation of Different Semiotic Representations of Paraboloids

In this research, we investigated whether the use of GeoGebra Augmented Reality (AR) can foster students in conceptualising a mathematical object by manipulating its different semiotic representations. We designed and implemented, with thirty university mathematics students, a teaching sequence on paraboloids using GeoGebra AR supported by GeoGebra 3D with the aim of fostering students??? work with different semiotic representations. All the activities carried out during the teaching case study were video-recorded, transcribed, and analysed according to Duval???s Theory. Results show how GeoGebra AR facilitated students in the manipulation of different semiotic representations of paraboloids involved by highlighting the cognitive activities of treatments and conversions which emerge while conceptualising the mathematical object at stake.

The Challenge of Choosing the Right Stimulation Target for Dystonic Tremor-A Series of Instructive Cases.

Thalamic deep brain stimulation (DBS) is established for medically refractory tremor syndromes and globus pallidus stimulation (GPi-DBS) for medically refractory dystonia syndromes. For combined tremor and dystonia syndromes, the best target is unclear. We present four patients with two different profiles whose clinical course demonstrates that our current analysis of clinical symptomatology is not a sufficient predictor of surgical success. Outcome parameters were assessed with observer-blinded video ratings and included the Fahn-Tolosa-Marin-Tremor Rating Scale (FTM-TRS) and the Unified Dystonia Rating Scale (UDRS). Two patients with "predominant lateralized action tremor" of the hands and mild cervical dystonia showed no relevant tremor improvement after GPi-DBS, but UDRS improved (mean, 45%). Rescue ventral intermediate nucleus of the thalamus (Vim)-DBS electrodes were implanted and both patients benefited significantly with a mean tremor reduction of 51%.Two other patients with "axial-predominant action tremor of the trunk and head" associated with cervical dystonia underwent bilateral Vim-DBS implantation with little effect on tremor (24% reduction in mean FTM-TRS total score) and no effect on dystonic symptoms. GPi rescue DBS was implanted and showed a significant effect on tremor (63% reduction in mean FTM-TRS) and dystonia (49% reduction in UDRS). The diagnosis of dystonic tremor alone is not a sufficient predictor to establish the differential indication of GPi- or Vim-DBS. Further criteria (eg, proximal-distal distribution of tremor/dystonia) are needed to avoid rescue surgery in the future. On the other hand, the course of our patients encourages rescue surgery in such severely disabled patients if the first target fails.

Study of English Grammar Teaching Practice in Senior High School under the Background of New Curriculum Standards

The English Curriculum Standards for Senior High Schools (revised in 2020, 2017 edition)(hereinafter referred to as the "New Curriculum Standards") advocates a three-dimensional dynamic grammar view of "form-meaning-use", which is oriented by language application. Under the guidance of thematic meaning, English grammar teaching in high school can try to start from the four levels of "introducing the theme, exploring the grammatical form", "exploring the theme, identifying the grammatical form", "expanding the theme, exploring the grammatical rules", and "sublimating the theme, applying the grammatical rules", so as to enable students to understand, analyze, summarize and use the grammatical rules in the context of the theme, and cultivate their comprehensive language application ability. Therefore, this paper expounds the basic principles that should be followed in grammar teaching practice under the background of the new curriculum Standards, and designs a teaching case of modal verbs in senior high school English grammar based on this principle, so as to explore the combination and application of the basic principles in the teaching of new curriculum standards and senior high school English grammar teaching.

A tale of three associate professors: A grassroots approach to supporting women in higher education

In higher education, gender imbalances continue to persist, particularly at senior academic levels and in university leadership. To explore practical ways to address this disparity, a grassroots initiative was established at an Australian University in 2015 and has grown into an ecosystem of mentoring and support for career advancement of academic women. Challenges and successes of the initiative from 8 years of operation are presented through a teaching case accompanied by teaching notes, including different benefits of grassroots initiatives for gender equity to both organisation and individuals.

Reform and practice of ideological and political teaching in the course of processing and storage of forage crops

The 6th document of the Ministry of Education in 2019 pointed out that ideological and political education should run through the whole process of talent training, insisting that the effect of "cultivating people by virtue" should be regarded as the fundamental standard to test all the work of colleges and universities. Forage processing and storage is based on the basic theory of maintaining and improving the nutritional value of forage feed and reducing the nutritional loss in the process of processing and storage. It focuses on the science of processing technology of forage. It is a professional course of grassland science major in higher agricultural schools. The teaching content involves botany, seed science, soil science, culture science, animal nutrition, ecology and other aspects, which contains rich ideological and political elements. With the purpose of "cultivating people by virtue", the paper explored the ideological and political elements, and integrated them with professional knowledge organically. Through the analysis of typical teaching cases, the reform and practice of ideological and political teaching of "Forage Processing and Storage" are promoted, and the correct values and scientific outlook are set up by the students in a subtle way.

PHILOSOPHY AND TEACHING METHODS OF CHINESE CHARACTER LITERACY EDUCATION BASED ON THE APPLICATION CONCEPT OF PALEOGRAPHY

The reform and practice of the Chinese character literacy teaching method based on the concept of paleography application can be employed to a certain extent and thus will improve the quality of Chinese character literacy teaching. This paper discusses the necessity and feasibility of applying ancient characters to Chinese character literacy teaching, discusses the epistemological and methodological issues of Chinese character literacy teaching, and expounds five teaching methods for the application of ancient characters to Chinese character literacy teaching, including didactic teaching method, case teaching method, theme-based teaching method, situational teaching method, and comprehensive teaching method. Different teaching methods are the deconstruction of Chinese character teaching goals, highlighting teaching objectives and priorities from different levels. They are not isolated and separated from each other, and teachers can actively choose and use teaching methods under the guidance of teaching objectives at different stages.

"Rheuma (be-)greifen"- Amultimodal teaching concept to improve rheumatology education for medical students

The German Society for Rheumatology, through its campaign Rheuma2025, aims to improve student teaching in order to ensure patient care for rheumatological patients in the future. To assess whether acombination of traditional and innovative educational methods provide both an improvement in the quality of teaching and an increase in the attractiveness of rheumatology as adiscipline. Establishment of the teaching concept "Rheuma (be-)greifen" consisting of five modules on patient history taking with acting patients, musculoskeletal ultrasound, arthrocentesis, 3Dprinting of pathological joints and virtual reality applications based on real patient cases in the curricular teaching of medical students. The evaluation of the teaching concept with 93students of medicine showed aconsistently high acceptance of all modules, which were rated as very effective or rather effective. Direct patient-related modules, such as history taking with acting patients, musculoskeletal ultrasound and arthrocentesis, received even higher acceptance than the visualization methods utilizing 3Dprinting and virtual reality. Innovative teaching methods can help to improve the acceptance of teaching in the field of rheumatology, especially when combined with classical teaching contents.

Next generation sequencing (NGS) interest in deciphering erythrocyte molecular defects' association in red cell disorders: Clinical and erythrocyte phenotypes of patients with mutations inheritance in PIEZO1, Spectrin ß1, RhAG and SLC4A1

We report here an instructive case referred at 16 months-old for exploration of hemolysis without anemia (compensated anemia with reticulocytosis). The biology tests confirmed the hemolysis with increased total and indirect bilirubin. The usual hemolysis diagnosis tests were normal (DAT, G6PD, PK, Hb electrophoresis) except cytology and ektacytometry suggesting an association of multiple red blood cell (RBC) membrane disorders. This led us to propose a molecular screening analysis using targeted-Next Generation Sequencing (t-NGS) with a capture technique on 93 genes involved in RBC and erythropoiesis defects. We identified 4 missense heterozygous allelic variations, all of them were described without any significance (VUS) in the SLC4A1, RhAG, PIEZO1 and SPTB genes. The study of the familial cosegregation and research functional tests allowed to decipher the role of at least two by two genes in the phenotype and the hemolytic disease of this young patient. Specialized t-NGS panel (or virtual exome/genome sequencing) in a disease-referent laboratory and the motivated collaboration of clinicians, biologists and scientists should be the gold standard for improving the diagnosis of the patients affected with RBC diseases or rare inherited anemias.

Priapism at Diagnosis of Pediatric Chronic Myeloid Leukemia: Data Derived from a Large Cohort of Children and Teenagers and a Narrative Review on Priapism Management.

Pediatric chronic myeloid leukemia (CML) is a very rare malignancy (age-related incidence 0.1/100,000) typically presenting with leucocyte counts >100,000/µL. However, clinical signs of leukostasis are observed at diagnosis in only approximately 10% of all cases and among these, priapism is infrequent. Here, we analyze data from pediatric CML registries on the occurrence of priapism heralding diagnosis of CML in 16/491 (3.2%) boys (median age 13.5 years, range 4-18) with pediatric CML. In the cohort investigated, duration of priapism resulting in a diagnosis of CML was not reported in 5 patients, and in the remaining 11 patients, occurred as stuttering priapism over 3 months (n = 1), over 6 weeks (n = 1), over 1-2 weeks (n = 2), over several days (n = 2), or 24 h (n = 1), while the remaining 4 boys reported continuous erection lasting over 11-12 h. All patients exhibited splenomegaly and massive leukocytosis (median WBC 470,000/µL, range 236,700-899,000). Interventions to treat priapism were unknown in 5 patients, and in the remaining cohort, comprised intravenous fluids ± heparin (n = 2), penile puncture (n = 5) ± injection of sympathomimetics (n = 4) ± intracavernous shunt operation (n = 1) paralleled by leukocyte-reductive measures. Management without penile puncture by leukapheresis or exchange transfusion was performed in 3 boys. In total, 7 out 15 (47%) long-term survivors (median age 20 years, range 19-25) responded to a questionnaire. All had maintained full erectile function; however, 5/7 had presented with stuttering priapism while in the remaining 2 patients priapism had lasted <12 h until intervention. At its extreme, low-flow priapism lasting for longer than 24 h may result in partial or total impotence by erectile dysfunction. This physical disability can exert a large psychological impact on patients' lives. In a narrative review fashion, we analyzed the literature on priapism in boys with CML which is by categorization stuttering or persisting as mostly painful, ischemic (low-flow) priapism. Details on the pathophysiology are discussed on the background of the different blood rheology of hyperleukocytosis in acute and chronic leukemias. In addition to the data collected, instructive case vignettes demonstrate the diagnostic and treatment approaches and the outcome of boys presenting with priapism. An algorithm for management of priapism in a stepwise fashion is presented. All approaches must be performed in parallel with cytoreductive treatment of leukostasis in CML which comprises leukapheresis and exchange transfusions ± cytotoxic chemotherapy.

The EU’s 2020 summit on the COVID recovery fund: leading the divided house to a consensus

Research methodology The writing of this case study was triggered by the numerous media reports in 2020 that talked about the EU nations losing its solidarity. EU being a very appropriate example of economic, monetary and customs union while teaching theories of economic integration and international relations, the post-pandemic approach of EU leadership to rebuild the crisis-ridden member nations seemed an excellent material for developing a teaching case study. The case study was written based on secondary data and published information available. Enough desk research was undertaken to build the characterisation of the protagonists and due diligence done to chronologically report all facts of the case as the story developed. It was decided to build the epilogue into the case study so that the case analysis had enough depth. Case overview/synopsis The case is set in 2020 when the global economy was reeling under the massive impact of a lockdown and the aftermath. The case study examines the model of economic union in international business and the various challenges that governance of an association of nations such as the 27 member EU can throw up. It examines the conflict of interest that can arise among member nations during critical circumstances such as the pandemic and its massive tolls. EU had established itself as a critical international trade player and had already proven their might as a united entity to the world trade partners, given the fact that they were not only a customs union but also a monetary union. In this scenario when the pandemic threw them into the whirlwind of lockdown-induced crisis, the united front of the mighty EU all but crumbled. As the worst-hit economies of Italy and Spain struggled to pull themselves back to normalcy, EU experienced one of its worst solidarity crises. EU’s president Angela Merkel and ally French President Emmanuel Macron with support from the EU Council’s President Charles Michel stepped forward to resurrect the badly hit economies. They viewed this as the best opportunity to bring about a united front by coming together at Brussels for a summit when lockdown eased up in July 2020. It was to be a show of unity to jointly bail out the severely affected member nations by grants rather than loans. The summit, however, snowballed into bitter arguments and open bickering between the wealthy and not-so-wealthy members, and they could not agree upon the issue of debt vs aid. The fact that the EU was an agglomeration of 27 nations, which were far from homogenous in socioeconomic status, not to speak of divided political ideologies, only added dimensions to the dispute. Negotiations repeatedly hit roadblocks. Can the EU leaders lead their bitterly divided house to a consensus? Complexity academic level The case is suitable for graduate and post-graduate levels. Management courses where international business studies, international trade blocs and global leadership are part of curriculum can use the case to teach concepts of “Regional economic integration”, “Economic and Political union” and theories of “International relations” and “Negotiation”. It can also be ideally used in an executive management programme on “Global Leadership” to highlight the complexities of “governance of international associations” and “consensus building amidst diversity”.

Solution of Fractional Heat-Like and Fractional Wave-Like Equation by Using Modern Strategy

Abstract This paper introduces a novel form of the Adomian decomposition (ADM) method for solving fractional-order heat-like and wave-like equations with starting and boundary value problems. The derivations are provided in the sense of Caputo. In order to help understanding, the generalised formulation of the current approach is provided. Several numerical examples of fractional-order diffusion-wave equations (FDWEs) are solved using the suggested method in this context. In addition to examining the applicability of the suggested method to the solving of fractional-order heat-like and wave-like equations, a graphical depiction of the solutions to three instructive cases was constructed. Solution graphs were arrived at for integer and fractional-order problems. The derived and exact solutions to integer-order problems were found to be in excellent agreement. The subject of the present research endeavour is the convergence of fractional-order solutions. This strategy is considered to be the most successful way of addressing fractional-order initial-boundary value issues in science and engineering. This strategy is presented here.

Different Cases of Leadership and Teaching in Higher Education

Higher education has a global structure including the influence of international trends. Such international composition naturally enrich diversity in universities. No doubt, generating diversified leadership team can help to establish scholarly environment in universities. Within this environment, scholarship of teaching and learning could be one of hot topic to empower international programmes. To this end, English language programmes expectedly gain importance to train students for global business sectors.&#x0D; &#x0D; In this issue of HEGP studies on different topics are covered. The first article, titled “English Language Teacher Education Programs at Turkish Universities: A Statistical Overview” by Asmalı analyzed the key characteristics of English Language Teacher Education programs in Türkiye. Asmalı stated that the decrease in the demand for English Language Teacher Education programs is a major challenge of these programs. Asmalı indicated that English Language Teacher Education in Türkiye needs careful planning in terms of academic employment and student quotas. The second article, titled “Striving for Diversity of Leadership: Governance in UK Higher Education Institutions” by Shafi, Clarke, Norman, and Andrews investigated the scholarship on developing the diversity of UK university boards and developed a practical toolkit to ensure board diversity in higher education. The study documented the barriers to achieving diversity in the UK higher education institutions boards. The third article of the journal, titled “Linking Sustainability and Spirituality: The University with a Soul” by Razak and Moten elaborated on key values that higher education needs to convey to link sustainability and spirituality. The fourth article of this issue, titled “Bibliometric Analysis of Research on Scholarship of Teaching and Learning in Higher Education” by Ertem and Aypay documented the results of a bibliometric analysis on research of teaching and learning in higher education. The study documented the influential outlets, topical foci, and key references in research on teaching and learning in higher education.

Building Higher-Order Thinking Skills Through Assessment of User Account Access

Abstract Given the fast-paced growth of innovative technologies and soft skill development required by the accounting profession, students need to enhance their knowledge of business systems, risk, information technology (IT) controls, IT auditing, emerging technology, and higher-order thinking skills (HOTS). This instructional case provides the opportunity for students to (1) understand foundational knowledge and perform testing on IT controls, (2) perform data analytics within Excel and CaseWare Analytics’ IDEA, and (3) analyze and evaluate IT testing results to formulate appropriate conclusions. As students complete each part of the case, they build on their information technology knowledge and analytical and evaluative HOTS. This case is best suited for faculty teaching undergraduate or graduate-level students in accounting information system (AIS), IT audit, or internal auditing courses.

Development of a Classification System for Live Surgical Feedback

Live feedback in the operating room is essential in surgical training. Despite the role this feedback plays in developing surgical skills, an accepted methodology to characterize the salient features of feedback has not been defined. To quantify the intraoperative feedback provided to trainees during live surgical cases and propose a standardized deconstruction for feedback. In this qualitative study using a mixed methods analysis, surgeons at a single academic tertiary care hospital were audio and video recorded in the operating room from April to October 2022. Urological residents, fellows, and faculty attending surgeons involved in robotic teaching cases during which trainees had active control of the robotic console for at least some portion of a surgery were eligible to voluntarily participate. Feedback was time stamped and transcribed verbatim. An iterative coding process was performed using recordings and transcript data until recurring themes emerged. Feedback in audiovisual recorded surgery. The primary outcomes were the reliability and generalizability of a feedback classification system in characterizing surgical feedback. Secondary outcomes included assessing the utility of our system. In 29 surgical procedures that were recorded and analyzed, 4 attending surgeons, 6 minimally invasive surgery fellows, and 5 residents (postgraduate years, 3-5) were involved. For the reliability of the system, 3 trained raters achieved moderate to substantial interrater reliability in coding cases using 5 types of triggers, 6 types of feedback, and 9 types of responses (prevalence-adjusted and bias-adjusted κ range: a 0.56 [95% CI, 0.45-0.68] minimum for triggers to a 0.99 [95% CI, 0.97-1.00] maximum for feedback and responses). For the generalizability of the system, 6 types of surgical procedures and 3711 instances of feedback were analyzed and coded with types of triggers, feedback, and responses. Significant differences in triggers, feedback, and responses reflected surgeon experience level and surgical task being performed. For example, as a response, attending surgeons took over for safety concerns more often for fellows than residents (prevalence rate ratio [RR], 3.97 [95% CI, 3.12-4.82]; P = .002), and suturing involved more errors that triggered feedback than dissection (RR, 1.65 [95% CI, 1.03-3.33]; P = .007). For the utility of the system, different combinations of trainer feedback had associations with rates of different trainee responses. For example, technical feedback with a visual component was associated with an increased rate of trainee behavioral change or verbal acknowledgment responses (RR, 1.11 [95% CI, 1.03-1.20]; P = .02). These findings suggest that identifying different types of triggers, feedback, and responses may be a feasible and reliable method for classifying surgical feedback across several robotic procedures. Outcomes suggest that a system that can be generalized across surgical specialties and for trainees of different experience levels may help galvanize novel surgical education strategies.
