The Present Role of Market Risks in the Financial Performance of Indonesian Banks Post-2007 Financial Crisis and Post-2016 Financial Technology Disruption
Authors: Karamoy Herman , Tasik Hizkia H. D.
Published: June 2023

The 2007-8 financial crisis and the 2016 technology disruption have motivated investors to be more aware of the financial performance of the banks in Indonesia. This study attempts to examine the strength of market risk post the financial crisis and financial technology disruption. To our knowledge, this is the first study to examine the advancement of market risk in the Indonesian banking industry following the crisis and disruption. Literature has shown that the role of market risk in other countries accentuates after the crisis. Using panel data from forty-nine banks listed in the Indonesia stock exchange during the 2009 – 2020 period, this study concentrates on the role of Market Risk Indicators (MRIs) in financial performance. The findings suggest that MRIs alter the profitability indicators. The effect of MRIs becomes more robust as moving further away from 2007. Additionally, there is no evidence that NIM has become a tool to manage risk.

Authors: Blackwood-Rhoomes Dawnette , Gordon John
Published: June 2023

Abstract mathematical thinkers in the fields of pure mathematics and theoretical computer science have contributed significantly to the body of knowledge that has fundamentally altered the course of human civilization and technological advances. Halpern and Butler have stated that “our future depends on our ability to think critically in a world that is growing more complex day by day”, and that critical thinking skills “should be a priority.” They concluded that “the ability of our students to think critically and abstractly is a matter of national importance.” This paper concerns itself with the implementation of viable strategies which can result in the development of the abstract mathematical thinker.
Teaching Online Courses for Undergraduate University Students: Challenges and Opportunities
Authors: Fraser Grant A.
Published: June 2023

The author taught several courses using online learning during 2020 and2021. These were mathematics courses at the undergraduate University level. They were given at California State University, Los Angeles. During this experience, the author encountered many challenges and obstacles. Some oft these can be attributed to the nature of the online process itself, but in other cases, idiosyncratic policies adopted by the University proved to be counterproductive to fundamental aspects of the teaching process. Such policies must be modified to improve the effectiveness of this type of teaching. In this paper, the author summarizes his experiences, with particular attention to the difficulties that were encountered. He also proposes alternative techniques that could be employed to make the learning experience more rewarding and satisfying for both the instructor and the students.

Developing Mathematical Reasoning: The Trap of Algorithms
Authors: Harris Pam
Published: June 2023

The role of mathematics education is to mentor students to reason like mathematicians, not parrot like robots. To this end, algorithms are incredible historical achievements, but are not helpful teaching tools. Traditional digitbased procedures limit student growth by allowing less sophisticated reasoning, which will not be sufficient for students to progress to more advanced mathematical concepts. This presentation illuminates the trap of teaching students to simply mimic steps and instead emphasizes logical deduction through mathematical relationships. Participants will engage in an instructional routine called “Problem Strings” to elucidate the way a mathematician might solve a problem. To inform effective curriculum design, they will also learn a nested hierarchy of reasoning domains that increase in sophistication, with each level featuring more advanced thinking.
Co-teaching in an Elementary Mathematics Education Methods Course: Growing Awarenesses
Authors: Husband Marc , Throop-Robinson Evan , Tucker Allison , Clarke Carolyn
Published: June 2023

Many prospective teachers (PTs) come to elementary mathematics teacher education classes reporting poor previous learning experiences. They often expect mathematics teacher educators (MTEs) will lecture them about how to teach mathematics differently and better. Subsequently, MTEs face challenges to respond to the expectations of their students and to cultivate experiences that support envisioning teaching and learning mathematics anew. One view of co-teaching involves MTEs interacting with students fluidly and responding in the-moment to their needs (Marzocchi et al., 2021). In this paper, we describe how we invited PTs to co-teach with us while their peers worked on mathematics tasks. Using Mason’s (1998) notion of awareness, co-teaching supports PTs’ and MTEs’ growing awareness of teaching moves that provide “sensitivities which enable [them] to be distanced” (p. 260) from the showing and-telling mathematics.
Media as Constitutive Factors for Paradigm Shifts in Mathematics
Authors: Lousis Michail
Published: June 2023

This study brings in serious evidence from the history of the development of the science of mathematics that knowledge is not an individual enterprise but rather social/collective in nature and is produced by collectives of humans with-media (Borba & Villarreal, 2005), which has not been presented by the conceivers of the notion. The study pinpointed that the media are components of the epistemic subject of mathematics, being neither auxiliary nor supplementary, but an essential, necessary, constitutive part of it. They are so pertinent that in the case of their absence, different knowledge is produced. Further, different media in use produce different knowledge. The media that are employed in the work alter, transform, redefine, and reorganize the practices, the contents, and the ways of knowing. Thus, media are epistemological, cognitive tools. Furthermore, the investigation stresses that the media are constitutive factors for paradigm shifts in mathematics. Keywords: mathematical cognition, humans-with-media, collective (social) nature of mathematics, paradigm shift.
Integrating Mathematics and Computer Science Using Squeak Etoys
Authors: Morge Shelby , Gordon Christopher
Published: June 2023

To innovate means to make changes or do something in a new way (Merriam-Webster, 2023). As a follow up to our Cambridge workshop, we will share howa technology tool, Squeak Etoys, can be used to engage primary students (ages 8-10 years old) in discovering the relationship between a fractional amount and angle measure using a circle model. Innovation in education involves creativity, adaptability, and accessibility (Kaltura, 2023). Squeak Etoys is a dynamic, accessible tool that allows students to develop computer models of various topics. When teachers integrate computer science within mathematics instruction, all students have access to computer science topics and are able to make connections, which leads to deeper understanding. In this paper, we describe a problem-based lesson and engage participants in the development of a Squeak Etoys computer model.

Innovative Experiential Practice(s) in Teacher Education: A Case Study in an Irish University
Authors: Oldham Elizabeth , Bray Aibhín
Published: June 2023

On the premise that experience of innovative practices is a key factor helping teachers and student-teachers to adopt them, this paper examines work done with serving, preservice and prospective teachers in Trinity College Dublin. For teachers and student-teachers, it focuses on use of the Bridge21 (Bridge to 21st Century Teaching and Learning) model of professional development, with participants experiencing constructivist, team-based, technology-mediated and project-based teaching and learning. Also, at a time of unprecedented teacher shortage, ways of attracting good candidates into teaching must be considered; hence, a module for undergraduate mathematics students allows prospective teacher education candidates to spend time experiencing school classrooms as assistants to teachers. Research indicating positive outcomes from these practices is reported, and possible developments are outlined.
In the Pursuit of a Course Design: A TPACK-based Geometry for Preservice Mathematics Teachers
Authors: Saralar Aras İpek , Birgili Bengi
Published: June 2023

Preservice mathematics teachers seem to need professional support regarding the use of educational technologies to teach geometry topics. Particularly, our previous study showed that when it comes to their technopedagogical content knowledge (TPACK), they self-report to need guidance to teach with technology. The purpose of this study was to develop a 14-week course to increase their TPACK in hopes of bridging the knowledge gap identified in earlier studies. This paper summarized the course content with a humble expectation to get valuable feedback from an international audience. The developed course included lessons on components of TPACK, which were found to require improvement to best meet future students’ needs in teaching geometry with technology. We hope that preservice teachers’ TPACK levels will be improved after the course. Keywords: Course design, design-based research, preservice mathematics teachers, technology, TPACK.
Non-routine Problem-solving Strategies
Authors: Shah Pari
Published: June 2023

Students constantly confront new problems both at school and in their daily lives. Therefore, they need to be flexible beyond knowing and applying various strategies. Because the strategy they use in one problem may not work in another, the ability to switch to another strategy is crucial. The problems with the greatest potential to improve flexibility are non-routine problems since they are challenging and require higher-order thinking skills. Non-routine problems compel students to think creatively and rationally and foster communication skills as students document and explain the strategies to others as well. It also helps them gain confidence as, they soon realise that they can independently determine appropriate strategies and successfully apply them. These problem solving skills are necessary as students these days are used to being told to follow a learned algorithm, which is basically spoon-feeding.
An Innovative Model of Teaching and Learning in Mathematics
Authors: Siadat M. Vali
Published: June 2023

We present the theory and practice of a research-based model of teaching and learning of mathematics at the college, coined the Keystone model. This is a model of dynamically assessing student learning and adjusting teaching practices. Keystone’s philosophy is grounded on the belief that all students can learn mathematics provided they are engaged in the learning process. This system views classroom as a learning community where through peer-topeer interaction and cooperation, all students achieve. Contrary to other programs that put the students in competition with one another, essentially pitting them against each other for grades, our program challenges students to cooperate so that all attain the standards of excellence. Keystone is an alternative model to traditional educational practices and its basic principles should be applicable to all disciplines.
Visible Maths
Authors: Văcăreţu Ariana-Stanca
Published: June 2023

Abstract The starting point of the Visible Maths series of workshops was the realisation that students have difficulties understanding mathematical concepts. I hypothesised that creating real objects that show mathematical concepts or ideas might support students’ understanding. The students involved in this project were 9th graders (14-15 years old). I worked with a professional designer for designing and implementing the workshops. During the first workshop we launched the task: “Choose a mathematical concept (e.g. radian, cone sections, trigonometric circle, function, number, Pascal’s triangle, etc.), design and make an object to illustrate the concept.” After five months, in the eighth workshop, the students presented the prototypes and the work process. This paper presents my experience with the Visual Maths workshops, and some of the implementation results.
Wellness Pedagogical Knowledge: Professional Development to Address STEM Teachers’ Needs
Authors: Zollman Alan
Published: June 2023

Covid-19 demonstrated to us that the traditional professional development was not enough to assist our teachers (Maher & Zollman, 2021). They needed intra-personal and inter-personal support beyond subject content knowledge, pedagogy content knowledge, and technological pedagogical knowledge. To meet their needs, we shifted our approach to included “Wellness Pedagogical Knowledge” in our workshops with teachers. These addressed teacher’s wellbeing, emotional support, and interests. We added topics for internal, selfregulating skills such as time management, setting priorities and stress management. We also included external, interpersonal skills such as empathy, patience, active listening, and teamwork. Lastly, we added teacher interests such as personal finance and how to separate scientific information from opinions and beliefs. Teachers accepted these ideas as a positive impact on them and their students.

This research is motivated by the fact that there are still problems faced by tertiary institutions, namely one of them is the lack of motivation from lecturers in their duties contained in the Tridharma and other important factors that affect lecturer performance include professionalism such as lecturer professional allowances or lecturer certification. This study aims to find out how the relationship between lecturer certification and the teaching quality of lecturers at STKIP Al Amin Dompu. The approach used in this study is a quantitative correlation approach with the type of ex-post facto.  The research population is all lecturers at STKIP Al Amin Dompu. The sampling technique used random sampling which totaled 28 lecturers.  Data collection techniques using a questionnaire. The data analysis technique used the product moment correlation test with SPSS type 29.00 for windows. The results of the study showed that there was a significant relationship between the two variables, namely lecturer certification and the teaching quality of lecturers at STKIP Al Amin Dompu. This can be seen from the significance value which is smaller than the significance level value or 0.01 <5% (0.05). In addition, the results obtained r count > r table of 0.533 > 0.361. Which shows a strong relationship between the two variables. This research is expected to become the view that lecturer certification is a factor to motivate lecturers in carrying out the tridharma but not to be a benchmark for lecturers in improving lecturer abilities, especially in teaching abilities.
Role of markedness in the perception of Bengali stops
Authors: Sarkar Sreeparna
Published: June 2023

Markedness is a theory that was developed on the basis of segmental patterns observed in speech output and has primarily been addressed in regard to speech production in previous studies. According to the Markedness Theory, marked segments are more difficult to produce due to an additional property or “mark” which requires more articulatory effort. However, its effects on speech perception are not discussed in the previous literature. This study examines the role of markedness in perception with Bengali stops. Bengali stops involve two types of markedness or additional properties, voicing and aspiration. Voiced stops (represented as D) are marked with respect to voiceless stops (represented as T), and aspirated stops (TH) are marked with respect to unaspirated stops (T). Voiced aspirated stops bear both additional properties (represented as DH). While the absence of a marked property may make segments easier to produce than those with the property, the question addressed here is whether the same holds true for perception. This study investigates the possibility that the opposite is what is observed. That is, the presence of additional properties may make segments more audible and identifiable. Additionally, this study also investigates whether the combination of multiple marks in the Bengali DH stops lead to a cumulative effect on perception with the best perceptual results for the DH stops. The results from this study show that this is, in fact, the case.

Published: June 2023

Issues of diseases and healthcare are very crucial to human life and survival. Africans have always sought to find holistic and impeccable remedies to diseases and sicknesses that disturb human life and survival. Africans being incurably religious have sought to employ religious perspectives in their healing systems. Ghanaians have from time immemorial employed their indigenous or traditional worldview in their healing system or approach to diseases and sicknesses. This paper explores the African indigenous practitioners’ approach to diseases, their causes and solution. It also looks at the traditional healing systems in the face of the Western approach to diseases or healing systems. This work is a result of a discussion of scholarly works on African indigenous religious approaches to diseases and traditional healthcare vis-a-vis the orthodox healing systems. It is the ardent hope of the authors that readers appreciate African indigenous healing systems and how they can be combined with orthodox healing systems to ensure holistic healthcare in contemporary society.

Spatial Heterogeneity in the Distribution of European Research and Development Funds and its Effects on Territorial Cohesion
Authors: Rubiera Morollón Fernando , Fernández García Tania
Published: June 2023

The latest research and development (R&D) framework programmes of the European Union (EU), “Horizon 2020” and “Horizon Europe”, have significantly increased the resources available to promote science and innovation in Europe. However, the strong competitiveness of the research teams and their search for excellence may cause inequality in the spatial distribution of investment effort in R&D. The aim of this paper is to analyse the geographic distribution of R&D spending in the EU. A greater concentration of funds is observed in the most advanced and dynamic economies, capable of promoting more competitive research teams and projects. Through an empirical analysis, estimated by a spatial convergence model, it is found that EU R&D funds are preventing cross-regional convergence in Europe by driving growth mainly in wealthier regions. Based on these results, it seems relevant to consider spatial correction mechanisms for the distribution of R&D resources so that they achieve greater territorial cohesion in Europe.

Sobre las estimaciones econométricas de las necesidades de gasto autonómicas: ¿son suficientemente robustas?
Authors: Vaquero García Alberto , Lago Peñas Santiago
Published: June 2023

El objetivo de este artículo es identificar y cuantificar econométricamente el impacto de los determinantes de las necesidades de gasto de las Comunidades Autónomas. La combinación de efectos fijos individuales que capturen diferencias interterritoriales no observables en preferencias o eficiencia de gasto, por un lado, con factores determinantes del gasto de escasa variabilidad, por otro, plantea problemas para los estimadores tradicionales. Para solventar esta limitación, se exploran especificaciones econométricas y estimadores alternativos. Los resultados muestran que los coeficientes estimados y su significatividad cambian sustancialmente, por lo que no está claro que puedan garantizar la robustez necesaria para sustentar una discusión política adecuada. Es necesario apostar por otras estrategias para el trabajo empírico que permitan estudiar las preferencias de gasto de las Comunidades Autónomas.

In the qualitative research, a semi-structured questionnaire was created for the purpose of data collection and submitted to eighteen creators of the department's conceptual documents. The obtained data were evaluated by open coding according to the grounded theory, one of the methods of systematizing qualitative data. The results show that the methods are used, but informally or in a modified form – adapted to the specifics of the department. Barriers to the use of methods, are primarily the varying level of competence of the creators, the inappropriateness of certain methods for certain types of documents, time pressure or the preference for an intuitive approach. The ideal strategy seems to be a combination of the intuitive and rational approach.
Introduction of Autonomous Combat Vehicles into the Czech Armed Forces
Authors: Kovanda Jan
Published: June 2023

The article addresses the issue of the emergence of new technologies and their impact on the capabilities of the Czech Armed Forces (CAF). A summary of the recommendations is presented. In particular, there is a need for a conceptual approach to the integration of new systems in order to avoid spontaneous purchasing, which could be very logistically demanding. The very rapid development in the field of unmanned autonomous systems using elements of artificial intelligence offers opportunities to use them in support of the tasks of CAF. Due to the breadth of this issue, the scope is limited to the area of the Special Forces, which introduce these new sophisticated means into use throughout the Ministry of Defence of the Czech Republic.

Koalas suffer unusually high rates of neoplasia. There has been a long-standing correlation between koalas with the koala retrovirus (KoRV) and development of neoplasia which has lacked a mechanistic explanation. We describe recent results that demonstrate that many KoRV integrations lead to neoplasia by (I) inserting into somatic cells preferentially near oncogenes, (II) inserting into germ cells near oncogenes predisposing koalas to cancer, and (III) transduction—replacing KoRV genes with oncogenes, resulting in drastic upregulation of the transduced gene. The high mortality associated with integration-driven promotion of neoplasia may explain the increased prevalence of dysfunctional recombinant KoRVs (recKoRVs), which, over time, could replace KoRV, thereby slowing the production of novel detrimental integration sites.

Soil-geographic Study in the Area of Iron Age Pits Sanctuary and a Middle Ages Settlement near the Kaptain Andreevo Railway Station
Authors: Sarafov Alexandar , Tcherkezova Emilia
Published: June 2023

This paper presents the results of soil investigation in the archaeological site 27 near the settlement Kapitan Andreevo (SE Bulgaria). The following soil types are recognized: Fluvisols, Vertisols, Luvisols and Planosols. Their spatial distribution is closely related to the Pliocene facial surface that consists of erosion, abrasion and accumulative deposits in the region and presents a transitional zone in the investigated archaeological area.These circumstances depend on the terrain and climate conditions over thousands of years and have determined the mosaic nature of the three soil types. The results support the archaeological investigation in the study area and were additionally filled with GIS-based analysis of the Digital Terrain Model (DTM) using open software GRASS GIS.
Extremely high flow within the Alpine catchments in the Rila Mountain
Authors: Seymenov Kalin
Published: June 2023

The study of high flow characteristics within the Alpine catchments represents one of the most challenging tasks for the modern hydrological science, because of high vulnerability response of these areas to the global and regional climate changes, including to the proven positive air temperature trends. The current picture of the hydro-climatic processes in the Rila Mountain – the highest mount within the Balkan Peninsula, is not exception. Study area covers eight Alpine catchment areas, located above 1600 m sea level in the Rila Mountain. The aim of this research is to perform a spatio-temporal analysis of the extremely high streamflow characteristics within the researched drainage basins. Study period includes six years in the beginning of the XXІ century: there are very dry (2001), very wet (2005) and four normal water years. The analysis is based of Threshold level method (TLM) with fixed constant threshold value: 5th percentile of all discharge daily data for the given term. Results obtained show the number of extremely high streamflow events ranges from 6 to 26 – for the catchments of the Stara River at Kostenets and the Blagoevgradska Bistritsa River at Bistritsa, respectively. The maximal duration of these events varies from 15 (for the Mesta River at Yakoruda) do 39 days (the Stara River at Kostenets), but the oneweek extremely high flow periods are most typical here (a frecquency to 88% of all cases). The temporal analysis shows a concentration of studied hydrological events during the spring season (in the months of April, May and June), when occurs also a high streamflow phase, due to the snow melting and rainfalls. An exception of this statement is the wettest year in Bulgaria from the beginning of this century – 2005. Then because of heavy prolonged rainfalls during the months of July, August and September, were detected sharp peaks of the hydrographs. Present work establishes some spatial differences of extremely high flow characteristics (time of occurring, duration, frequency) in study area due to the slopes exposition peculiarities. Results obtained supplement previous scientific works and give new information about the risk hydrological processes within the mountainous catchment areas in Bulgaria.
