Analisis Pengaruh Net Interest Margin Dan Non Interest Income Terhadap Return On Asset Pada Badan Usaha Perbankan Di Bursa Efek Indonesia
Authors: Permatasari Anita
Published: April 2022

The primary objective of this study is to determine which dominant factor to influence the profitability of banks in Indonesia. There are the two main factors that affect the profitability of the banks. The first one is Net Interest Margin as lo known as NIM and the second one is Non Interest Income also known as NII. Firstly, bank is in charge of collecting funds from the people and to channel it back to the community for various purposes. By doing this, Net Interest Margins are generated by the difference between saving rate and credit rate. Secondly, bank gains Non Interest Income by charging fee for banking services such as transfer fee, letter of credit, safe deposit box rental, etc. With higher Net Interest Margin and Non Interest Income, banks will achieve higher profitability. This research concludes that Net Interest Margin dominates over Non Interest Income in Indonesian’s banking. This research also concludes that Net Interest Margin and Non Interest Income can complement each other to increase banking sector profitability.

Effect of sample treatment on the elastic modulus of locust cuticle obtained by nanoindentation
Authors: Li Chuchu , Gorb Stanislav N , Rajabi Hamed
Published: April 2022

Cuticle is one of the most abundant, but least studied, biological composites. As a result, it has contributed very little to the field of biomimetics. An important step to overcome this problem is to study cuticle biomechanics by means of accurate mechanical measurements. However, due to many reasons, mechanical testing on fresh cuticle specimens is not always possible. Hence, researchers often use stored specimens to measure properties of arthropod cuticle. Our knowledge about the influence of different treatment methods on cuticle properties is currently very limited. In this study, we investigated the effect of freezing, desiccation, and rehydration on the elastic modulus of the hind tibial cuticle of locusts obtained by nanoindentation. We found that all the mentioned treatments significantly influence cuticle properties. This is in contrast to previous reports suggesting that freezing did not significantly influence the elastic modulus of native cuticle specimens tested in bending. In the light of our data, we suggest that changes of the elastic modulus of cuticle are not solely due to changes of the water content. Our results provide a platform for more accurate measurements of cuticle properties.
THE IMPACT OF DIGITAL MATURITY IN ORGANIZATIONAL CULTURE: EXPLORATORY RESEARCH AT FALLUJAH UNIVERSITY
Authors: Awad Mahmood J.
Published: April 2022

This study aims to find out the extent of the impact of digital maturity as an independent variable in organizational culture as a dependent variable at the University of Fallujah. This is to support it determine the extent of maturity reached by the university as a result of the transformation of most of its work to the digital aspect due to the outbreak of the Covid-19 epidemic and the accompanying decisions; most of which were calling for the adoption of digital means to manage institutional life, whether in terms of doing business inside the university or delivering the lectures to students. The questionnaire has been adopted as a data collection method from a study sample at the university, by selecting an intended random sample of (73) from its specific population (91). Following the identification of the study sample and data collection, (SPSS) program was used to analyze the data depending on a group of statistical means as (weighted mean, coefficient of variation, standard deviation, relative importance, coefficient of determination, rank correlation coefficient, simple linear regression analysis). The research has reached at a set of results, the most important of which is the existence of a statistically significant correlation and effect between the independent variable (Digital Maturity) and the dimensions of dependent variable (Organizational Culture) in the university in general. However, a clear weakness has been identified in the relationship between some dimensions of the two variables. In line with this result, the university administration must work to address the existing weaknesses in order to strengthen its digital maturity process.

Résumé introductif Récemment la vie professionnelle a été confrontée à des changements radicaux à cause des révolutions économiques, technologiques et sociales. La flexibilité du travail est devenue un mot clef pour les organisations, une condition nécessaire pour la survivance des marchés du travail national dans un monde de compétition globale, qui pousse les travailleurs modernes à s’adapter à des circonstances flexibles et à se préparer à des carrières multiples (Atkinson, 1984 ; Reilly, 1998 ; Peiro et al., 2002). Dans ce cadre le concept de bien-être devient particulièrement pertinent en référence aux stratégies de planification de la carrière des jeunes générations qui doivent être prêtes à accepter une carrière flexible et sans confins. Le but de cette étude est d’analyser la relation entre bienêtre subjectif et flexibilité du travail. On a conduit huit entrevues avec un groupe de travailleurs stables et temporaires dans le but d’analyser l’attitude envers la restructuration rapide et radicale du marché du travail après l’adoption de politiques flexibles et pour capturer la construction discursive du sens de la flexibilité et du bien être. La recherche adopte une approche qualitative de l’analyse diatextuelle (Mininni, 1992, 2003, 2005) afin de mieux comprendre la relation entre parlants, sens et contexte d’énonciation. Plus en détail, une attention particulière a été donnée aux stratégies communicatives utilisée par les parlants qui ont été révélés grâce aux nombreuse traces pragmatiques et linguistiques (par exemple figures rhétoriques, présuppositions, choix stylistiques, etc.) et qui consentent à mettre en évidence la récurrence de répertoires interprétatifs spécifiques (Potter et Wetherell, 1987) .

Eventual differentiability of coupled wave equations with local Kelvin-Voigt damping
Authors: Bchatnia Ahmed , Souayeh Nadia
Published: April 2022

In this work, we consider a coupled wave equations with partially and locally distributed Kelvin-Voigt damping, where only one equation is dissipative.

Under the assumption that the damping coefficient changes smoothly near the interface of the damped and undamped regions, we investigate the effectiveness of the indirect control, and we prove that the associated semigroup is eventually differential.
Optimization and learning with nonlocal calculus
Authors: Nagaraj Sriram
Published: April 2022

Nonlocal models have recently had a major impact in nonlinear continuum mechanics and are used to describe physical systems/processes which cannot be accurately described by classical, calculus based "local" approaches. In part, this is due to their multiscale nature that enables aggregation of micro-level behavior to obtain a macro-level description of singular/irregular phenomena such as peridynamics, crack propagation, anomalous diffusion and transport phenomena. At the core of these models are nonlocal differential operators, including nonlocal analogs of the gradient/Hessian. This paper initiates the use of such nonlocal operators in the context of optimization and learning. We define and analyze the convergence properties of nonlocal analogs of (stochastic) gradient descent and Newton's method on Euclidean spaces. Our results indicate that as the nonlocal interactions become less noticeable, the optima corresponding to nonlocal optimization converge to the "usual" optima. At the same time, we argue that nonlocal learning is possible in situations where standard calculus fails. As a stylized numerical example of this, we consider the problem of non-differentiable parameter estimation on a non-smooth translation manifold and show that our nonlocal gradient descent recovers the unknown translation parameter from a non-differentiable objective function.

Projection-based reduced order models for parameterized nonlinear time-dependent problems arising in cardiac mechanics
Authors: Cicci Ludovica , Fresca Stefania , Pagani Stefano , Manzoni Andrea , Quarteroni Alfio
Published: April 2022

The numerical simulation of several virtual scenarios arising in cardiac mechanics poses a computational challenge that can be alleviated if traditional full-order models (FOMs) are replaced by reduced order models (ROMs). For example, in the case of problems involving a vector of input parameters related, e.g., to material coefficients, projection-based ROMs provide mathematically rigorous physics-driven surrogate ROMs. In this work we demonstrate how, once trained, ROMs yield extremely accurate predictions (according to a prescribed tolerance) – yet cheaper than the ones provided by FOMs – of the structural deformation of the left ventricular tissue over an entire heartbeat, and of related output quantities of interest, such as the pressure-volume loop, for any desired input parameter values within a prescribed parameter range. However, the construction of ROM approximations for time-dependent cardiac mechanics is not straightforward, because of the highly nonlinear and multiscale nature of the problem, and almost never addressed. Our approach relies on the reduced basis method for parameterized partial differential equations. This technique performs a Galerkin projection onto a low-dimensional space for the displacement variable; the reduced space is built from a set of solution snapshots – obtained for different input parameter values and time instances – of the high-fidelity FOM, through the proper orthogonal decomposition technique. Then, suitable hyper-reduction techniques, such as the Discrete Empirical Interpolation Method, are exploited to efficiently handle nonlinear and parameter-dependent terms. In this work we show how a fast and reliable approximation of the time-dependent cardiac mechanical model can be achieved by a projection-based ROM, taking into account both passive and active mechanics for the left ventricle providing all the building blocks of the methodology, and highlighting those challenging aspects that are still open.
Impacts of Changing Postharvest Agricultural Practices on Abundance of Waste Grain in California's Central Valley
Authors: Matthews Luke J. , Petrie Mark , Eadie John M.
Published: April 2022

Agricultural waste grains are significant for providing nutrients for wintering waterfowl in California. Rice and corn comprise 56% of their nutrient needs in the Central Valley and changes to agricultural practices, such as postharvest treatments, could impact these food resources. Currently, limited data exist on how postharvest treatments in rice and corn fields affect the abundance of waste grain, yet these data are essential to determine the carrying capacity of agricultural lands for wintering waterfowl. To address this knowledge gap, we estimated the abundance of waste grain (kg/ha) using dry field transects, dry field soil cores, and flooded field (wet) soil cores. In 2016 and 2017, we sampled 84 rice fields and 47 corn fields. Our results indicate that the abundance of waste rice varied significantly among postharvest treatments. Fields that received no postharvest treatment (stubble left standing; no incorporation of straw) had the greatest amounts of waste rice, whereas fields that were disced, disced and rolled, or burned provided the least amount of waste rice. The average abundance of waste rice across all postharvest treatments was 320 kg/ha in dry fields (arithmetic mean; geometric mean = 228 kg/ha; soil core samples). Estimates of waste rice in flooded fields averaged only 169 kg/ha (geometric mean 98 kg/ha; soil core samples), significantly lower than in the same fields prior to flooding. Variation in the abundance of waste corn was greater than that of waste rice. Fields that did not receive any postharvest incorporation had the greatest abundance of waste corn, 233 kg/ha on average (arithmetic mean; geometric mean = 72 kg/ha), whereas fields that were incorporated (disced or disced and rolled) contained significantly lower abundance of waste corn, averaging 50–60 kg/ha (arithmetic mean; geometric mean = 5–10 kg/ha). The average, across all postharvest treatments, was 159 kg/ha of waste corn (geometric mean = 25–34 kg/ha). Our results suggest that postharvest practices affect the abundance of waste grain in rice and corn fields; changes in these practices could impact food availability for wintering waterfowl. Our results also indicate that the method of sampling waste grain can influence estimates of residual grain abundance.
The practice theme in mathematics education : Development of a French-English collaboration on the role of theories
Authors: Abboud Maha , Coles Alf
Published: April 2022

In this introductory article, we describe how the Special Issue came about, as a result of three years of collaboration. We show how this collaboration developed with a focus on the role of theory. We draw out themes across the individual papers, making use of the concept of ‘boundary objects’ that have allowed the comparison and enrichment of our different perspectives. We suggest that the work of bringing together researchers, from different traditions and on a sustained basis, is more important now than ever, in a context in which policy makers are increasingly looking at ‘solutions’ to problems in education from the other, seemingly more successful, countries (e.g. as measured by international comparison tests). We conclude with questions for further research, both for our particular collaborative group and more widely.

Theory and the Role of the Mathematics Teacher Educator: comparing the use of video in teacher education sessions in France and England
Authors: Coles Alf , Horoks Julie , Chesnais Aurélie
Published: April 2022

In this article, we compare and contrast practice-based approaches to using video in the context of mathematics primary and secondary teacher education. We look across country boundaries, with a focus on theory, in relation to the role of the mathematics teacher educator. We place the article in the context of developing interest in the facilitation of professional learning of mathematics teachers using video. In contrasting our different practices, we ask: what guides the planning of video sessions? what guides the action of facilitators during sessions? and, what are the intentions, in terms of teacher learning? We uncover similarities and differences in our practices which we theorise in terms of our espoused, enacted and intended theories, as mathematics teacher educators.
L’analyse sémiotique de l’activité mathématique, une nécessité didactique dans le contexte de l’adaptation scolaire
Authors: Houdement Catherine , Petitfour Edith
Published: April 2022

La recherche que nous menons cherche à comprendre ce qui se joue entre les acteurs (élèves, enseignant) et qui pourrait éclairer certaines difficultés à faire apprendre des mathématiques dans le contexte de l’adaptation scolaire. Pour ce faire, nous étudions en particulier la dimension sémiotique de l’activité mathématique. Le support est une situation d’apprentissage de la numération décimale, proposée à trois élèves handicapés atteints de déficience intellectuelle dans un Institut Médico-Éducatif. Les analyses s’appuient sur les différents signes activés lors des interactions, lorsqu’ils font des mathématiques (Arzarello, 2006 ; Radford, 2003). L’étude pointe la présence de « malentendus sémiotiques » et le rôle des interactions, y compris sociales, entre élèves ou avec l’enseignante dans l’activité.
Contextualiser pour enseigner les mathématiques : un enjeu de formation
Authors: GREFEM
Published: April 2022

S’attarder aux questions de contextualisation dans l’enseignement et l’apprentissage des mathématiques constitue, comme le montrent les travaux de recherche en didactique des mathématiques et les contraintes institutionnelles, un enjeu important à considérer dans la formation des enseignants. C’est à cet enjeu que s’attarde cet article. Trois cas de pratiques de formation à l’enseignement des mathématiques à l’Université du Québec à Montréal (UQAM), ciblant un même contenu mathématique (la division), sont analysés sous l’angle de la contextualisation. Ces pratiques, analysées a posteriori, proviennent d’un cours de didactique des mathématiques s’adressant à de futurs enseignants de mathématiques au secondaire (deux premiers cas) et d’un cours de didactique des mathématiques s’adressant plutôt à de futurs enseignants du primaire (troisième cas). Une contextualisation y est sollicitée de manière explicite ou émerge du travail mené par les futurs enseignants. Pour chacun des cas, nous dégageons, par une démarche d’analyse inductive, le sens que prend, dans l’action, cette contextualisation, et la fonction qui lui est attribuée. Une lecture transversale de ces cas montre une richesse des significations associées à la contextualisation, et permet de cibler des enjeux de formation.

Coordinating representation registers: linear algebra students' understanding of orthogonal Legendre polynomials in the inner product space ℙn in a technology-assisted learning environment
Authors: Caglayan Günhan
Published: April 2022

The purpose of this research study was to understand how linear algebra students in a university in the United States make sense of the orthogonal Legendre polynomials as vectors of the inner product space ℙn in a DGS (Dynamic Geometry Software)-MATLAB facilitated learning environment. Math majors came up with a diversity of innovative and creative ways in which they coordinated semiotic registers (Duval, 1993, 2006) for understanding inner products of Legendre polynomials along with other notions inherent in the inner product space, such as Triangle Inequality, Pythagorean Theorem, Parallelogram Law, Orthogonality and Orthonormality, Coordinates Relative to an Orthonormal Basis. Research participants not only produced such creative inner product space visualizations of the Legendre polynomials with the associated integral inner product 〈f,g〉 = ∫1-1 f(x)g(x)dx on the DGS, but they also verified their findings both analytically and visually in coordination. The paper concludes by offering pedagogical implications along with implications for mathematics teaching profession and recommendations for future research.

Évolution et interinfluence des modes d’agir, parler et penser les fractions dans deux problèmes multiplicatifs
Authors: Houle Virginie , Venant Fabienne , Barrera-Curin Raquel Isabel
Published: April 2022

Based on studies focusing on the roles of language in the teaching and the learning of mathematics, three dimensions are distinguished - acting, talking and thinking - interrelated. In order to explore the interactions and progressive transformations of these dimensions during the teaching and the learning of fractions, a teaching sequence was experimented in a specialized class. The sequence is composed of a network of problem focusing on multiplicative relationships inherent in the concept of fraction. In this article, we present the a priori and a posteriori analyses of two of these problems. These analyses are carried out in a didactic framework enriched with a specific perspective on the modes of acting, speaking and thinking the multiplicative relationships in question.
Favoriser le passage à la visualisation non iconique par le recours à une ingénierie didactique pour faciliter la transition primaire/secondaire en géométrie
Authors: Duroisin Natacha , Beauset Romain , Lucchese Jessica
Published: April 2022

There is a rupture of didactic contract about the visualization learning during the transition from primary to secondary (Perrin-Glorian & Godin, 2018). If iconic visualization is exercised in primary education, the acquisition of non-iconic visualization – which is fundamental – is left to the learners at the beginning of secondary school. This article describes the results of a belgian study, based on quasi-experimentation plan in Belgium, which is part of the didactics of mathematics and cognitive sciences. The aim of the authors is to evaluate the implementation of a didactic engineering based on dimensional deconstruction allowing the progressive development of non-iconic type visualization in learners at the end of primary education. The results are used to guide the work of mathematics teachers.
Visual Arts in U.S. Geometry Textbooks Aligned with the Common Core Standards
Authors: González Gloriana
Published: April 2022

This study investigates visual arts references in five U.S. high school geometry textbooks aligned with the Common Core State Standards for Mathematics. In all of the textbooks, architecture is the most commonly used context. More than half of the visual arts references are in the exercises. Congruence is the domain most often used, followed by Similarity, Right Triangles & Trigonometry. The visual arts references support the four traditional arguments justifying the geometry course but mostly support the goal of teaching geometry in ways that allow students to draw upon their intuition.
Savoirs véhiculés par les manuels scolaires français et québécois à propos de l’aire. Une étude comparative
Authors: Anwandter Cuellar Nathalie Silvia , Tremblay Steve
Published: April 2022

This article presents a comparative study of French and Quebec textbooks on the notion of area. Several research studies have raised students’ difficulties in understanding the concept of area, and recent work suggests studying these difficulties in connection with the learning opportunities offered by textbooks, which are a tool widely used by teachers. In order to highlight the similarities and differences in the knowledge set out in the textbooks of two territories and to interpret them according to the learning of the pupils, we have built a praxeological reference model using the Anthropological Theory of Didactics (TAD). Our results show similar limitations in French and Quebec textbooks, in particular the strong focus on the numerical dimension of the area to the detriment of the elements contributing to a conceptualization of this notion.
Qu’apporte la notion de portée d’une technique à l’étude de la dynamique praxéologique ?

Published: April 2022

We look at educational institutions as dynamic systems where praxeologies exist only as a result of a praxeological dynamic. In this article, we study some aspects of praxeological dynamics using, in particular, the notion of technique reach (theoretical, pragmatic and institutional) and competition between techniques. Two case studies illustrate praxeological dynamics concerning the study of the resolution of second-degree equations in the French educational system. One of the contributions of this article is to provide tools for curriculum analysis and textbooks.
Exemple, explication et processus de démonstration
Authors: Barrier Thomas , Hajji Azzedine
Published: April 2022

The article looks at the proving process in mathematics from a didactic perspective. The study seeks to identify what metamathematics knowledge is at stake when mathematicians produce proof of implications with universal quantifiers. For this reason, we propose a modelling of the proof process – from the manipulation of examples to the finished product – based on dialogic logic tools. This modelling leads us to a characterization of the enunciative position which is needed to elaborate proofs. The results are derived from two cases: one in arithmetic integers, another in plane geometry. Their comparison allows us to discuss the limits of a transversal approach to this meta-mathematical knowledge without taking into account the specificity of mathematical fields.
Formation et évolution des représentations fonctionnelles-spontanées à travers un apprentissage socioculturel
Authors: Hitt Fernando , Quiroz Rivera Samantha
Published: April 2022

The present research aims to understand the role of the students’ functional-spontaneous representations through the study of the pupils’ external spontaneous representations in the process of solving a problem research situation. Through a qualitative methodology, the spontaneous representations of secondary students in the learning of covariation between variables are analysed. A particular goal is to study how these representations are likely to evolve through internal communication of students and through communication and validation with their pairs. Hence the importance of having a method that promotes a social construction of learning. In our case, we have opted for a learning process in a sociocultural environment: ACODESA (Collaborative Learning, Scientific Debate, Self-reflection and Institutionalization). From this perspective, in this paper, we consider collaborative research that allows the researcher to acquire knowledge about the teacher's practice, and vice versa, the teacher acquiring research knowledge in the mathematics classroom through the evolution of pupils’ representations. The results show that the functional-spontaneous representations are the engine of the learning process of mathematical concepts.

The impact of the evolution into master courses on the expertise in proportinality problem solving among students and primary school trainee teachers. The aim of the research is to assess, in the French context, the impact of the evolution of the teachers trainings into master courses on the development of the expertise in proportionality problem solving. For this purpose, we will describe three successive periods from 2008 to 2015, each representing a teaching model. We will consider, for each of these models, the added value of every education year, the influence of the competitive exam, the specifics of the obtained licence. The exploitation of a questionnaire, constituted by 19 scaling and elargement problems, proposed to 1138 students, allows to check if the studied education model has an effect on the success and failures patterns, a as well as the levels of expertise that ensues.
Équations algébriques et activité mathématique en calcul mental : regard sur les défis d’enseignement
Authors: Proulx Jérôme , Lamarche Marie-Line L. , Tremblay Karl-Philippe
Published: April 2022

This article explores students’ and teachers’ strategies when solving algebraic equations without paper and pencil or any other material aid. The enactivist notions of problem-posing offer conceptual grounds to engage in analysis of students’ and teachers’ strategies, and in their comparisons. This leads to the exploration of differences in the nature and origin between the solving processes of students and those of teachers, as well as challenges in relation to teaching and learning of algebra equation solving. Final remarks reflect on the potential of being sensitized to the nature of these differences in solving processes.
La catégorisation des tâches et du travailleur-sujet : un outil méthodologique pour l’étude du travail mathématique dans le domaine des probabilités
Authors: Nechache Assia
Published: April 2022

The categorization of tasks and the worker-subject: a methodological tool for the study of mathematical work in the probability field This article focuses on the study of the mathematical work produced after the resolution of probabilistic tasks as well as the students’ role in the elaboration of this mathematical work. This led us to categorize mathematical tasks (simple, standard, rich) according to their level of epistemological and cognitive demand. This categorization is associated with students’ learning in the form of a worker-subject (jobber, technician, engineer). Using this categorization and the Mathematical Working Space (MWS) model, we analyzed the implementation of a probabilistic task in two tenth grade classes. This analysis of the two class sessions allowed us to characterize the transformations of the nature of the tasks by the teachers during its implementation. These transformations generate a decrease in the level of cognitive demand of the task and also in the students’ role in solving the task.

Published: April 2022

In several countries including France, there is a growing interest for the teaching and learning of algorithmics and programming at school and college level. It is then necessary to question the objectives of this teaching and learning, and to propose controlled implementations. This article, written by a researcher in cognitive ergonomics and a researcher in didactics, aims at assessing some research results in this field, on the basis of research work conducted sporadically since thirty years. It first attempts to show the permanence of questions related to beginners’ conceptual difficulties, and then tackles the issue of learning situations. Then it takes stock of results obtained in psychology of programming, focusing on a conceptual field precisely identified around the concept of computer variable. The conclusion gives evidence of a broad field of research now open.

This essay examines a little-studied aesthetic collaboration between Aimé Césaire and Wifredo Lam to depict doves and a bird of prey (called “menfenil”) in text and image. “Colombes et menfenil” was the title of a selection of poems by Césaire that was published in Hémisphères magazine in 1944 with an illustration by Wifredo Lam. Both birds also appear in Césaire’s Cahier d’un retour au pays natal and Lam’s illustrations of the Spanish translation of this poem published in Cuba the previous year. They go on to recur in later paintings by Lam: “Menfenil” (1947), “Lunguanda yembe” (1950), and “La colombe noire” (1959). The birds in question have archetypical significance as symbols of peace and war that connect to the history of colonialism. I propose with this essay a critical dialogue with Césaire and Lam’s work on these birds to diffuse the conquest-thinking that informs the symbolic economy and contributes to normalizing the persistence of racialized hierarchies embedded in the history of colonial dispossession and exploitation. In their collaborative aesthetic recasting of these archetypal bird figures, I argue that both poet and painter symbolically take them over to take flight from conquest.

In the era of COVID-19 planners, and more broadly, city administrators and policy makers, have learned to cope with the accelerated pace of change, the broad band of uncertainty, and the need for rapid decision-making strategies. This, in the context of ever more diverse communities and greater reliance on technology as an effective response to the social and public health challenges of the pandemic. “Smart” cities harness distributed communication and service delivery technologies to enhance the quality of urban life. The voices of citizens from marginalized and under-served populations, such as older adults and people with disabilities, are vital to the development of inclusive smart cities. In this paper expanding an inclusive policy design approach is proposed that uses ‘personas’ to actively engage those citizens.

The event we are facing at a global scale, the COVID-19 pandemic, can be considered a real death blow to the real markets, in general, as well as to a local heritage-based tourism market, in particular. The closing of both near and distant “borders”, due to the imposed social-spatial limitations - as an early answer to the pandemic - has hugely and mainly affected the micro, small and medium businesses’ fabric within their local contexts. This article aims to identify how and if an alternative tourism offer might take/give a kind of advantage of the urban features and cultural layers of Tirana, by positioning it as safe tourism in the current long wave of post-pandemic. Tirana is proposed as an experimental open lab. The adopted survey methodology was based on both traditional urban analyses, as well as on an e-survey aimed to catch the overall common inclination in the city's vocation for an unconventional tourism offer. The paper is mostly focused on the survey as the base material from which to get further information to be used in subsequent co-planning and co-designing phases.
A Study of Health Insurance Fraud in China and Recommendations for Fraud Detection and Prevention

Healthcare insurance fraud influences not only organizations by overburdening the already fragile healthcare systems, but also individuals in terms of increasing premiums in health insurance and even fatalities. Identifying the behavioral characteristics of fraudulent claims can help shed light on the development of artificial intelligence and machine learning technologies to detect fraud in health information system research. In this paper, a theoretical model of medical insurance fraud identification is proposed, which characterizes the judgment variables of fraud from the three dimensions of time, quantity, and expenses. The model is verified with large-scale, real-world medical records. Our study shows that, in comparison with claims made by normal people, fraudulent claims usually have a greater frequency of hospital visits, and more medical bills, accompanied by higher amounts of medical expenses. An interesting discovery is that the price per bill for fraudulent cases is not statistically different from the normal cases.
Defining medical simulators for simulation-based education in EUS

Published: April 2022

Choosing the right simulator for tasks in simulation-based education in medicine will affect the trainees’ skills. However, there is a shortage in the vocabularies used for describing medical simulators and the contextual usage of simulators. We propose methods for approaching the task of choosing and defining the simulators needed, regardless of it being an acquisition or development process. It is advocated that efforts are made in defining the simulator's requirements before making any choice in regards to development processes. Multiple advantages are attained by keeping the simulator simple, both educational and development wise. Issues on validating simulators are discussed and highlighted as actions where interprofessional communication is likely to fail. The following conventional terms in medical education are problematic in regard to establishing a clear communication: Virtual reality, fidelity, validation, and simulation. The text is finalized in a short discussion on applying the methods in an EUS/endobronchial ultrasound (EBUS) context. The work is the authors’ interpretation of an invitation having the title “Development of EUS and EBUS training models and simulators.”

Background and Objectives:

EUS has evolved into a therapeutic modality for gastrointestinal disorders. Simulators, ex vivo models, and phantoms are the current teaching methods for therapeutic EUS (TEUS). We create and evaluate a high-fidelity simulated live animal model (HiFi SAM) for teaching endoscopists TEUS.

Materials and Methods:

Designing a curriculum that uses HiFi SAM and enables trainees to perform realistic procedures with expert mentors.

Results:

Twenty-seven trainees participated in a 3-day program with 6 h of theoretical and 14 h of hands using life HiFi SAM. Eighteen experts participated. Twenty-two (20–25) TEUS were defined for each HiFi SAM, and 616 were performed in all. Of 616/264 (43%) were evaluated with a mean of 88 per course (ranging between 80 and 95). Ninety-one percent (240/264) of the procedures were completed successfully. In 24, success was not achieved due to technical and/or model problems. Student rating of HiFi SAM was: 71% excellent rating (scale 8–10) and 95% excellent/good. The HiFi SAM procedure evaluation was (scale 1–5): fine-needle biopsy: 4.79, radiofrequency: 4.76, common bile duct and gallbladder drainage: 4.75, cystic drainages: 4.72, neurolysis: 4.55, microbiopsy: 4.50, and hepatogastric drainage: 4.04, with an overall satisfaction rate of 4.56 (91%). A short survey showed: 83% would recommend absolutely (17% most likely), 33% think that ITEC training was sufficient for their practice, and 66% would like additional training, especially more practice in specific techniques rather than more clinical case discussion. Regarding impact on their practice, 66% of the trainees started a new procedure and/or noted improvement in previous ones.

Conclusion:

HiFi SAM is a complex model; however, experts and trainees are satisfied with the training this new curriculum provided.
The Art of Pharmacy
Authors: Mehlman Kaylee

Often, pharmacists grapple with demonstrating the cost-benefit of their work. This is a difficult objective, even when pharmacists implement services that increase patient safety. So, how do practitioners quantify their work and present it to decision makers: an employer, a third-party payer, CMS, or even congress? How to shape their perceptions of pharmacists as irreplaceable members of the health care team, in a fashion commensurate with proper compensation for the value a pharmacist brings to the multidisciplinary team? The author interviews Stacey Ranucci, the director of pharmacy at Integra/ Rhode Island Primary Care Physicians Corporation with the goal of proving the indirect cost-savings associated with pharmacist interventions.
