Published: January 2021

This research examined the relationship between cultural festival experience and subjective well-being among festival attendees. In this connection, this study captured the perceptions of 192 festival attendees' attending the cultural festival of "Virasat" in India on the four subdimensions of festival experiences (i. e., music experience, festival atmosphere, social experience, separation experience) and subjective well-being. Accordingly, this study adopted structural equation modeling (SEM) and hierarchical regression analysis to examine the relationship between the study constructs. Results that emerge from this study point towards the presence of a significant positive relationship between cultural festival experience and subjective well-being. Furthermore, of the four dimensions of festival experience, music experience and separation experience, in that order, were found to be the most potent predictors of subjective well-being. Social experience and festival atmosphere only minimally augmented predictability of subjective well-being over and above music experience and separation experience. Accordingly, the findings of this study are expected to aid cultural festival organizers to design events that elicit exhilarating festival experiences that, in its turn, is expected to augment subjective well-being among event attendees. Drawing extensively from subjective well-being research in India that suggests factors like sociodemographics, personal characteristics, economic conditions, and purchasing power parity contribute only moderately, if not significantly, to the levels of subjective well-being among the residents in India, the findings of this study situates cultural festival experience as a possible trigger that augments subjective well-being among Indians in a collectivist cultural context.
A Narrative Study of South African Community Members’ Experience With an International Service-Learning Program
Authors: Doughty Jeremy R.
Published: January 2021

At a time when higher education institutions in the United States are emphasizing global citizenship, more universities are designing and delivering international service-learning (ISL) programs. With the growth of ISL, critical questions must be raised about how these programs affect communities. Despite the centrality of reciprocity in the service-learning paradigm, the extant literature focuses primarily on the effect of ISL programs on students. The purpose of this narrative study was to explore how the stories of members of a South African community-based organization aligned with the principles of democratically engaged ISL programs. The author spent two weeks collecting data at a primary school in a predominantly Black African, Xhosa-speaking township in the Western Cape province of South Africa. The findings concentrate on the cultural meaning that participants gave to the U.S. students’ behavior and highlight areas for improvement within the ISL program. A number of practical recommendations for higher education professionals are presented.

En un momento en el que las instituciones de educación superior de los Estados Unidos están haciendo cada vez más hincapié en la ciudadanía global, muchas universidades están diseñando y ofreciendo programas internacionales de aprendizaje en servicio (ISL en inglés). Con el crecimiento del ISL, debemos comenzar a plantearnos preguntas esenciales acerca de cómo estos programas afectan a las comunidades involucradas. A pesar de que el concepto de reciprocidad es la base del paradigma del Aprendizaje en Servicio, la literatura existente se centra principalmente en el efecto que tienen estos programas en los estudiantes. El propósito de este estudio fue indagar cómo las experiencias de los miembros de una organización comunitaria sudafricana se alineaban con los principios de los programas de ISL implementados. Pasé dos semanas recopilando datos en una escuela primaria predominantemente de raza negra y de habla xhosa, en un municipio de la provincia del Cabo Occidental de Sudáfrica. Los hallazgos se concentran en el significado cultural que los participantes le dieron al comportamiento de los estudiantes de EE.UU., destacando las áreas a mejorar dentro del programa ISL. También se presentan varias recomendaciones prácticas a tener en cuenta por los profesionales de la educación superior.

Spectroscopic Investigation of Laser-Induced Graphene Plasma
Authors: Khalaf Madyan
Published: January 2021

In this paper, graphene plasma was obtained through the interaction of the fundamental radiation from a pulsed Nd:YAG laser at the fundamental wavelength of 1064 nm focused onto a solid plane of graphene material. This reaction was carried out under conditions of an atmospheric status. The resulting plasma was tested using an optical emission spectroscopy technique. The temperature of the electrons is calculated by the tow line ratio of C I and C II emission lines singly ionised, and the density of the plasma electron is calculated with Saha-Boltzmann equation. The upper limit of the electron temperature was approximately 1.544 eV. The corresponding electron density was 11.5×1015 cm-3. Then the electron temperature decreased when the energy was 300 mJ and it was near 1.462 eV, corresponding to the density of those electrons 8.7×1015 cm-3.

Die zentrale Rolle von Aufgaben als Träger der Vermittlungsprozesse in der Ausbildung in Stochastik
Authors: Borovcnik Manfred
Published: January 2021

The present paper deals with tasks in the teaching of stochastics. Yet, mathematics education as a whole entity is at stake. Tasks serve a goal: namely, to understand the concepts better so that one may work on similar and more different tasks to come to reasonable results. We also include logic, which seems clear as mathematics is based on logic. Then we elaborate on the value of tasks in mathematics and in stochastics teaching. The historic emergence of concepts and the individual cognitive growth of concepts provide a rich source for tasks. Further points of our analysis are how to characterise stochastics tasks and how to develop task systems that may serve the goal of learning stochastics well. Finally, we discuss some tasks we use in our teaching and provide background knowledge about the intention connected with them. We illustrate our perception of stochastics and how we try to support our students to stabilise their own conceptions by the details of a solution to one task, which we hand out to our students. Some conclusions about the value of tasks are drawn at the end. Classification: D80, K10, M10, U40.

Fehlerhaftes und Falsches beim mathematischen Denken – Melioration durch Metakognition
Authors: Sjuts Johann
Published: January 2021

Faulty and false understanding in mathematical thinking are visible signs of learning. Their appearance and their overcoming are integral parts of the associated processes. It is therefore important to identify and correct the faulty and wrong elements. A revision results in an improvement, a melioration. Tasks that involve a risk of error or falsity trigger metacognitive activity. This leads to corrections and improvements. Thus, a melioration by metacognition occurs.

Why are they mistaken?
Authors: Somfai Zsuzsa , Szöllösy András S.
Published: January 2021

In this study we are trying to illustrate with three examples that students’ typical mistakes in solving mathematical problems are very much worth analysing, because their explanation often unfold that they are not caused by an insufficient knowledge of mathematics, but before or after solving the mathematical problem at different phases of translation of the problem from everyday language to mathematical notation, and then translation of the solution back to everyday language. If the mathematical formulation of a problem presented in a natural language is sensible at all, whether it is a correct mathematical representation of the problem or not; it represents an interpretation of the problem as exposed in the everyday language text. We are examining students’ misinterpretations trying to find reasonable explanations to them and draw methodological conclusions to overcome them. Classification: C30, D70.

Starting from the quote from Hermann Weyl given in the title a ramble is undertaken through the development of the notion of function with special emphasis on the question whether the values are associated following a law. On the one hand, this shows a success story of the interplay of this notion and of infinitesimal calculus. On the other hand, one finds impressive examples of overgeneralizations.

It is worth turning on GeoGebra 3D
Authors: Jakab Enikö
Published: January 2021

I am a PhD student at the Doctoral School of Mathematics and Computer Science at University of Debrecen in the topic of Mathematical Competence Development with ICT. In this article, I present some examples, where the 3D version of GeoGebra can be applied successfully not only in research but also in everyday work. I have picked examples that require spatial representation but where it is much more complicated and less effective to achieve through concrete manipulatives than through any 3-dimensional dynamic geometric program. However, the two-dimensional version of any dynamic geometry program could be used to construct a figure, but besides easy constructing, formatting the figures is easier in the 3D version.

Kannst du das System schlagen? Wetten im Sport als Kontext für die Kombination der Ideen der klassischen, statistischen und subjektivistischen Wahrscheinlichkeit
Authors: Vancsó Ödön , Varga Eszter
Published: January 2021

The motivational value of the context is clearly demonstrated by students in classroom situations posing the title question. This excellent real-life question triggered the design of a special instructional sequence culminating in the addressed problem and aiming to combine different approaches to probability. Considering students’ usual struggle with the field, this attempt may prove valuable. As in the history of Stochastics, investigating the rationality behind the system of odds requires parallel handling of chances and expected value, and can lead to a deeper understanding of complex mathematical models. Recently, Series of Problems have been in the center of attention of the Complex Mathematics Education Research Project in general, as an important characteristic of the Hungarian Guided Discovery approach. Our design roots in this highly problem based tradition and adopts some of Tamás Varga’s ideas in instruction. In our paper, the details and structure of the designed teaching material will be displayed utilizing the tools of this research. Following centuries of tradition, sports betting is flourishing nowadays, particularly benefitting from the opportunities of online forums. Providing entertainment for many, it has great motivational value for students, who often pose the particular question in the title. This question is spot-on: gambling is a highly regulated, nevertheless always lucrative market. From an educational point of view, sports betting gives us a more complex perspective on probability than combinatorial games. History and teaching practice both suggest that the concept of probability bears serious cognitive load, and students often burdened with biases that makes the heart of the concept elude them. Furthermore, instruction sometimes lacks the adequate means to harmonize even the correctly introduced aspects of probability, leaving the students with either fragmented or contradicting ideas. In our paper we will make an attempt to connect the classical (laplacian), statistical (frequentistical) and subjectivistic (bayesian) approaches of probability through a gradually constructed task sequence organized around sports betting. We hypothesize that the investigation of the rationality of odds can foster a more integrated understanding of the concepts probability and expected value.

Public-Private Partnerships in Alberta, Canada: Towards the Institutionalization of Policy Reform
Authors: Opara Michael
Published: January 2021

The deployment of public-private partnerships (P3s) in Alberta, Canada has stalled following the suspension of the program in 2016. While P3s have become increasingly popular, the dynamics of P3 institutionalization remain unclear and overlooked. In response to Casady et al.'s (2018) call, this study aims to investigate the nature and extent of P3 institutionalization using Alberta's program as an effective longitudinal case study. This study finds that Alberta's P3 program, facing the pressures of limited funding availability and a previously failed partnership attempt, was initiated as an experimental effort designed to fill a serious infrastructure gap and motivated by existential political interests, but without the necessary institutional and organizational anchors to ensure program stability, permanency and continuity. Furthermore, Alberta's P3 program has become the object of ideological contestation between recent successive governments. Following Johnson et al. (2006), this study contends that Alberta's P3 program has stalled at the “diffusion stage” and unable to transition to the “general validation stage” needed for its widespread acceptance as an institutionalized model of infrastructure delivery

Published: January 2021

Operasi amfibi merupakan Operasi Gabungan TNI yang mengintegrasikan berbagai jenis kekuatan yaitu kapal, pesawat udara dan pasukan pendarat dalam suatu serangan terhadap pantai musuh dan/atau berpotensi dikuasai musuh dan bersifat kelautan. Oleh karena itu, dalam melaksanakan operasi amfibi dibutuhkan data kelautan untuk menunjang operasi tempur laut yaitu data tentang laut dan lingkungannya atau data Hidro-oseanografi sebagai produk Pusat Hidrografi dan Oseanografi TNI-AL (Pushidrosal). Untuk mendukung pemenuhan data-data tersebut, Pushidrosal telah mendirikan stasiun meteorologi permanen sistem telemetri dengan menggunakan peralatan Automatic Weather Station (AWS) yang mampu mengirim data online melalui sinyal GPRS, yang didirikan di daerah operasi dan latihan TNI-AL yang salah satunya didirikan di Singkawang Kalimantan Barat. Dengan adanya stasiun meteorologi permanen yang menggunakan sistem telemetri ini, Pushidrosal dapat mengumpulkan data meteorologi di daerah operasi dan latihan secara realtime dan termonitor langsung dari kantor Pushidrosal di Jakarta.

Data meteorologi yang didapatkan dari stasiun meteorologi antara lain berupa data temparatur/suhu udara, lembab nisbi, tekanan udara, radiasi matahari, curah hujan dan kondisi angin. Data-data tersebut merupakan parameter-parameter meteorologi atau biasa disebut parameter cuaca. Dengan melakukan pengamatan terhadap parameter-parameter tersebut tentunya akan diperoleh informasi cuaca di daerah pengamatan. Selain mendapatkan informasi cuaca dari pengamatan parameter-parameter tersebut, dengan melaksanakan pengolahan dari hasil pengukuran kondisi angin dapat dihitung tinggi gelombang perairan daerah penelitian. Kebutuhan data cuaca sebagai bagian dari Data Cumemu (Cuaca Medan Musuh) dalam tahapan perencanaan operasi tempur laut, menjadi tanggung jawab TNI AL khususnya Pushidrosal.

Pengolahan data hasil pengukuran stasiun meteorologi Pushidrosal di Singkawang akan memperlihatkan karakteristik cuaca berupa temparatur/suhu udara, lembab nisbi, tekanan udara, radiasi matahari, curah hujan dan kondisi angin di daerah Perairan Singkawang. Pengolahan dan perhitungan data kondisi angin akan menunjukkan kondisi tinggi dan periode gelombang di Perairan Singkawang. Data karakteristik cuaca, kondisi tinggi dan periode gelombang sangat dibutuhkan dalam membuat suatu perencanaan operasi dan latihan pendaratan amfibi, agar operasi dan latihan dapat berjalan dengan baik serta keselamatan personil dan material yang terpenuhi.

Published: January 2021

As learners seek more flexible learning opportunities, and employers become gradually more open to accepting alternative forms of credentials, there is a need to improve the visibility and quality of the online information available about such opportunities. This information includes not only the descriptions of formal and non-formal learning opportunities, from full degree programmes to optional courses and MOOCs, but also the credentials learning opportunities can lead to and by whom these credentials are recognised. The new Europass initiative of the European Union is a major step forward in this respect, offering the possibility to search for both learning and employment opportunities via a platform that will support a variety of different credentials. Building on the Europass Learning Model, the Erasmus+ ECCOE project makes a significant contribution to this future platform, by defining specific quality criteria for evaluating both learning opportunities and their credentials. This paper describes the methodology applied for the quality review of online descriptions with the ultimate aim of developing a catalogue showcasing learning opportunities that meet the criteria defined by the project. This methodology concerns two levels: (a) the actual process designed and implemented transnationally for the first iteration of over 100 learning opportunity descriptions, and (b) the two PDCA (Plan, Do, Check, Act) quality improvement cycles applied to refining the process itself. The paper also presents the results of this first iteration and formulates recommendations relevant for learning opportunity providers. Future work involving stakeholder consultation is also presented, as are the synergistic interactions between this research and the overall ECCOE project outcomes within the wider context of European work on Digital Credentials and open, online and flexible learning.

Authors: Proskurina Kseniya , Yevtifieieva Olga , Mala Olga , Mashtaler Viktoriya
Published: January 2021

The purpose of the research is to work out a routine method for the quantitative determination of the total amount of hydroxycinnamic acids in chicory herb growing in Ukraine. The presence of chlorogenic and caffeic acids was experimentally proven by comparing the TLC profiles of solutions of the chicory extract and standard substances of hydroxycinnamic acids. According to the chromatogram, the chemical composition of the ethanol extracts was qualitatively constant and did not depend on the series of plants collected in different places (7 regions of Ukraine) and in different years (2017 and 2018). The water-alcohol solutions of 8 chicory herb samples had the absorption maximum at the wavelength range from 326 to 330 nm, which was typical for phenolic acids. Chlorogenic acid was chosen as a marker substance for the quantitative determination by direct spectrophotometry. The value of the specific absorbance (556.21(λ=327 nm)) of chlorogenic acid in the concentration of 10.08 µg/ml in ethanol 50% was determined. The total amount of hydroxycinnamic acids was found to be 1.87% for the sample of 2017, for the samples of 2018 in the range of 4.00–6.61%. The method proposed is acceptable for standardization of the medicinal plant raw material.

Cette recherche vise à caractériser l’impact de la mise en place du cadre législatif imposé par la transcription en droit français de la directive européenne Solvabilité II sur la gouvernance des sociétés d’assurance mutuelles. Appuyée sur l’étude de trois cas de mutuelles considérées comme majeures en France, l’article montre comment ces organisations adaptent le modèle de gouvernance édicté par Solvabilité II à celui issu des valeurs mutualistes. Elle met notamment en évidence les spécificités revendiquées par leurs dirigeants en la matière et questionne la place donnée à la rémunération de ces derniers comme mécanisme de gouvernance au sein des mutuelles. Enfin, elle souligne le rôle important joué par les autorités chargées de la transcription, du suivi et du contrôle dans la mise en place de la directive européenne.
Ministères et charismes dans les principales traditions chrétiennes
Authors: Chalamet Christophe
Published: January 2021

Penser tout « ministère » en Église comme un « charisme », c’est-à-dire comme une réalité donnée par l’Esprit-Saint en vue de l’édification de l’Église, voilà l’un des enjeux importants de la théologie des ministères, aujourd’hui comme hier, à la suite notamment des écrits pauliniens. Cela peut nous conduire à mettre en évidence, avant de nous intéresser à ce qui distingue les laïcs des clercs, le socle commun que représente le sacerdoce (ou le ministère, compris ici au sens de « service ») de tous les fidèles. Malgré tout ce qui sépare encore les protestants des catholiques-romains et des orthodoxes sur les questions qui ont trait aux ministères, d’importantes avancées ont été faites depuis le milieu du XX e siècle sur la dimension « charismatique » des ministères. Le présent article met en lumière certaines de ces avancées, comme aussi certaines spécificités propres à chacune de ces trois traditions ecclésiales.
Instituer l’ininstituable
Authors: Joubert Thibault
Published: January 2021

La crise des abus sexuels commis par des clercs interroge la cohérence de la théologie catholique des ministères et le risque d’épuisement institutionnel des dons de l’Esprit saint. Le pôle charismatique n’est pas extérieur à l’institution mais il est un rappel intérieur de sa propre vocation et nul ne devrait pouvoir s’en arroger la propriété ni prétendre en épuiser l’infinie diversité. Pour envisager la place des ministères pastoraux dans la communauté, il convient de tenir un paradoxe : ce qui édifie l’autorité dans l’Église est en même temps ce qui la corrige et la décentre d’elle-même. La constitution eschatologique de l’Église implique pour l’autorité une non-disponibilité radicale à la fois de son fondement et de son objet. Une telle perspective vient corriger tout régime d’eschatologie réalisée qui ne prendrait pas en charge l’historicité du rapport de l’Église à son essence.

Endophthalmitis Twenty-One Years After Cataract Surgery
Authors: Ma Justin P. , Robbins Cason B. , Finn Avni P. , Feng Henry L. , Fekrat Sharon , Vajzovic Lejla
Published: January 2021

The authors report a case of an 81-year-old female who presented with sudden onset of light perception vision and intraocular inflammation. After several months of continuing symptoms despite antibiotics, an aqueous tap culture grew
Cutibacterium acnes
. The patient had cataract surgery 21 years prior, and had no intervening trauma, intraocular procedure, or endogenous source. The presumed diagnosis was
C. acnes
endophthalmitis with significantly delayed onset. Capsulectomy and intraocular lens removal resolved the patient's symptoms. In rare cases,
C. acnes
endophthalmitis may present as recurrent inflammation despite an extremely remote history of cataract surgery, mimicking a virulent, acute-onset endophthalmitis despite antibiotic administration.

Construire en terre et bois au Chalcolithique à Petko Karavelovo (Bulgarie)
Authors: Bacoup Paul
Published: January 2021

Le site de Petko Karavelovo, en Bulgarie, est le terrain d’une étude architecturale exhaustive depuis 2017. Cette étude applique une méthodologie déjà éprouvée sur d’autres sites du monde égéo-balkanique. L’objectif est d’éclairer les techniques de construction utilisées au cours du Chalcolithique (4900-4300 avant notre ère) par les bâtisseurs en étudiant le bois de construction et la terre à bâtir. Il devient ainsi possible de noter les éléments de continuité et les innovations dans l’architecture. À Petko Karavelovo, les matériaux employés ainsi que les techniques d’assemblage et de fondation sont restés les mêmes au cours du Chalcolithique, indices d’une transmission des savoir-faire et de l’existence d’une même tradition technique. En revanche, les modes d’agencement de la terre à bâtir et du bois de construction évoluent et reflètent les choix communautaires, voire personnels.
Le savoir-faire métallurgique : témoin d’une dynamique sociale ?
Authors: Baeriswyl Philippe
Published: January 2021

Des techniques de décoration à l’objet fini, on ne connaît, la plupart du temps, la métallurgie et l’orfèvrerie qu’au travers des artefacts découverts lors des fouilles archéologiques. Ainsi, les découvertes « métalliques » datant de l’époque mycénienne à Argos montrent un haut degré de technicité artisanale et témoignent d’une demande, émanant d’une élite sociale, « en objets de luxe », dont la provenance demeure néanmoins incertaine en l’absence d’atelier métallurgique mis au jour. La découverte, à Argos, d’un four à coupellation pour le raffinage de l’argent datant de la période submycénienne (SM) ou du début de la période protogéométrique (PG) présente de ce fait d’autant plus d’intérêt. En effet, elle montre que le raffinage de l’argent était effectué en Argolide au xie-xe siècle av. J.-C. – durant la période succédant à l’époque mycénienne et nommée à tort « Dark Ages » – et que le procédé de coupellation, qui est techniquement avancé, y était pratiquée. Ainsi, à l’inverse de l’époque mycénienne, il y a, à Argos au Submycénien, un atelier métallurgique, mais aucun de ses produits. Ce four témoigne dès lors de la pérennité d’un savoir-faire métallurgique sans toutefois pouvoir prouver une continuité dans la production artisanale du site. Ainsi, en sus des considérations techniques liées au four et au procédé de coupellation, nous nous pencherons sur le fait qu’un savoir-faire artisanal peut témoigner de la dynamique sociale et de l’évolution de l’établissement argien, à la transition entre l’âge du Bronze et celui du Fer, tant d’un point de vue local que régional.

First-Time Leaders and Implicit Leadership Theory
Authors: Walczak Steven
Published: January 2021

First-time leaders may find themselves thrust into very stressful situations for their teams and organizations at large. First-time leaders in corporations, the classroom, sports, the military, and politics should understand how stress changes the way followers perceive their leader and the ideal traits for a leader through changing leadership prototype schemas. Implicit leadership theories, social information processing, and cognitive psychology suggest that stress can influence the activation of schema. Changing leadership prototype schemas of followers may affect subsequent productivity and efficiency. This chapter examines if leadership prototype schemas change under stress and recommends ways first-time leaders can respond to these changing schemas, including how female first-time leaders who are often initially perceived as more sensitive leaders can utilize changing perceptions and ideal leader prototypes under stressful conditions.

Published: January 2021

The increasing trend of integrating diverse community of students and faculty in higher educational institutions brings with it challenges. It is important to look at the challenges that leaders face if gender diversity is not considered in their decision making. Does gender diversity even matter in the way their decisions are made? Does gender diversity affect the selection of leadership? It is important to understand as to what extent growing gender diversity in colleges and universities has an impact on decision making for leadership in higher institutions.
