PENDEKATAN EKONOMI DALAM POLITIK INTERNASIONAL
Authors: Setiyo Utomo
Published: March 2020

Masalah ekonomi telah muncul dalam politik internasional sejak Revolusi Industri di Eropa dan Amerika Serikat pada tahun 1880-an. Dalam periode ini masalah menciptakan pola hubungan konflik di antara negara-negara untuk menciptakan kompetisi untuk menaklukkan sumber daya ekonomi yang terletak di dalam atau di luar wilayah mereka. Sayangnya, itu menjadi kurang penting karena hubungan internasional telah didominasi oleh politik kekuasaan dan kepedulian militer sampai perang dunia pecah. Pasca Perang Dunia II dan Perang Dingin, masalah ekonomi menjadi pendekatan sentral dalam politik internasional. Kehancuran pascaperang dan keruntuhan sosialisme-komunisme di Uni Soviet dan Cina mengakibatkan ekonomi dunia dalam hal kapitalisme liberal menjadi pemenangnya. Penguatan atau regionalisme ekonomi dan globalisasi telah menciptakan sejumlah lembaga ekonomi yang mengatur interaksi dan integrasi ekonomi nasional ke dalam regional dan global. Pola hubungan internasional lebih ditentukan oleh masalah ekonomi daripada poltik atau ideologi. Meskipun, masalah ekonomi tidak hanya menjadi perpaduan antara negara-bangsa untuk bekerja sama tetapi juga sumber konflik untuk memperebutkan sumber ekonomi. Selain itu, globalisasi sebagai fondasi tatanan dunia telah menciptakan kesenjangan besar antara negara maju dan negara berkembang dan kurang berkembang, dan menciptakan kemiskinan internasional.

GPS IMTUVŲ KALIBRAVIMAS TAIKANT KALIBRAVIMO BAZES
Authors: Skeivalas Jonas , Putrimas Raimundas
Published: March 2020

GPS imtuvų kalibravimo standartų bei normatyvinių aktų ar instrukcijų nėra sudaryta.
Tam tikra prasme galima teigti, kad GPS imtuvai kalibruojasi patys. GPS imtuvų, priimančių siunčiamus GPS
palydovų didelio tikslumo nešlio dažnių virpesius (Δf/f ≈ 10–14), generatoriai (sintezatoriai) pagal tuos
virpesius sukuria tokio pat dažnio virpesius. Taip vyksta todėl, kad GPS imtuvų kvarcinių generatorių sukurtų
virpesių dažnių tikslumas nėra didelis (maždaug Δf / f ≈ 10–8), o priimtų iš GPS palydovų virpesių dažnis
yra pasikeitęs dėl Doplerio efekto. Taigi GPS imtuvuose sukuriamų virpesių dažnis yra maždaug toks pat kaip
ir priimtų iš palydovo signalų. Kadangi tokia procedūra dar neužtikrina šimtaprocentinio dažnių sutapdinimo,
tai signalų parametrų matavimo rezultatų apdorojimo procedūrose nustatomos GPS imtuvo generatoriaus virpesių
dažnio (bei laikrodžio eigos) pataisos. Straipsnyje nagrinėjamas GPS imtuvų kalibravimas, nustatant imtuvais
išmatuotų koordinačių prieaugių pataisas, taikant didelio tikslumo kalibravimo bazių matavimo rezultatus.
Kalibravimo bazių atkarpos matuojamos įvairiomis kombinacijomis. Matavimai GPS imtuvais atliekami taikant
fazių dvigubųjų skirtumų modelį. Matavimų rezultatai apdorojami mažiausiųjų kvadratų metodu, taikant parametrus
ir sąlygines parametrines lygtis. Apdorojimo procedūromis apskaičiuojamos taškų koordinačių prieaugių,
išmatuotų GPS imtuvais, pataisos. Gautos formulės koordinačių prieaugių išlygintųjų reikšmių
kovariacijų matricai įvertinti.

Kinetic Models of Tangential Discontinuities in the Solar Wind
Authors: Neukirch T. , Vasko I. Y. , Artemyev A. V. , Allanson O.
Published: March 2020

Kinetic-scale current sheets observed in the solar wind are frequently approximately force-free despite the fact that their plasma β is of the order of one. In situ measurements have recently shown that plasma density and temperature often vary across the current sheets, while the plasma pressure is approximately uniform. In many cases these density and temperature variations are asymmetric with respect to the center of the current sheet. To model these observations theoretically we develop in this paper equilibria of kinetic-scale force-free current sheets that have plasma density and temperature gradients. The models can also be useful for analysis of stability and dissipation of the current sheets in the solar wind.
Seroprevalence of Middle East Respiratory Syndrome Corona Virus in dromedaries and their traders in upper Egypt
Authors: Sayed Amal SM , Malek Safaa S , Abushahba Mostafa FN
Published: March 2020

Introduction: Camel trade in Egypt depends mainly on importation. Seemingly healthy imported camels are responsible for the ingress of serious diseases into Egypt. A striking example of this concerning public health globally is the Middle East respiratory coronavirus (MERS-CoV) which causes case fatalities of over 34%. Here, we determined the seroepidemiological situation of the MERS-CoV in imported camels and their traders in Upper Egypt.

Methodology: Sera of sixty-three dromedaries and twenty-eight camel traders were recruited (January 2015-December 2016). The age, gender, and sampling locality of each sampled camel and human were obtained. Semi-quantitative anti-MERS-CoV IgG ELISAs which utilize the purified spike protein domain S1 antigen of MERS coronavirus (MERS-CoV S1) were used to detect specific IgG antibodies against the virus.

Results: The data showed that 58.73% of imported camels and 25% of traders had antibodies specific to MERS-CoV. Interestingly, like seroreactive camels, all seropositive humans were apparently healthy without any history of developing severe respiratory disease in the 14 days prior to sampling. Having specific antibodies among the examined camel sera was significantly different (P < 0.0001) in relation to various sampling localities, gender and age groups. In contrast, the seropositivity rate of MERS-CoV IgG in humans did not differ significantly by any of the studied factors.

Conclusions: The current study provides the first serological evidence of occupational exposure of humans to MERS-CoV in Africa. Additionally, it reports that imported camels could be implicated in introducing MERS-CoV into Egypt. Accordingly, application of strict control measures to camel importation is a priority.
Prevalence, co-infection and antibiotic resistance of Escherichia Coli from blood and urine samples at a hospital in Jamaica
Authors: Cheung Donna A , Nicholson Alison , Butterfield Tiffany R , DaCosta Marsha
Published: March 2020

Introduction: Escherichia coli (E. coli) is a very common uro-pathogen and pathogen of bloodstream infections (BSI) in Jamaica. The aim of this study was to examine this organism’s prevalence, determine co-infection rates and assess antibiotic resistance patterns.

Methodology: In the absence of automated systems, data on all E. coli isolates identified at the University Hospital of the West Indies in Kingston, Jamaica during the first six months of 2008 and 2012 was collected and sorted. Data were analyzed using IBM SPSS Statistics version 20 for Windows.

Results: A total of 1188 isolates (1072 from urine and 116 from blood) was analyzed. Patients with E. coli BSI were older than those with E. coli urinary tract infections (UTI) (55.3 years vs 42.4 years, p < 0.05) and both had a female predominance. Sensitivity profiles in 2012 for E. coli in blood and urine were highest for the carbapenems, Amikacin and Nitrofurantoin and lowest for the fluoroquinolones and Trimethoprim-sulfamethoxazole. Based on antimicrobial susceptibility patterns, Nitrofurantoin was identified as an appropriate choice for empiric therapy for UTI. Ten antibiotics were noted in this study to have developed statistically significant antibiotic resistance. Patients with E. coli BSI had a co-infection E. coli UTI rate of 39%.

Conclusions: Resistance patterns change drastically in a few years making frequent antimicrobial susceptibility profiling necessary. Further studies would be beneficial in guiding management of these patients.

Published: March 2020

Introduction: Microbial translocation (MT) markers are indicators of HIV-related immune activation, but reference values are mostly derived from European or North American populations and could be substantially different in populations living in developing countries. Here we evaluate possible differences in MT markers levels in HIV+ pregnant women of different geographical provenance.

Methodology: This study is nested within an observational study of pregnant women with HIV in Italy. Women were dichotomized on the basis of provenance in two groups of European (n = 14) and African (n = 26) origin. Soluble CD14, lipopolysaccharide-binding protein (LBP) and intestinal-fatty acid binding protein (I-FABP) were measured in plasma samples collected between the first and second trimester of pregnancy.

Results: Demographic and viroimmunological characteristics were similar between groups, although European women were more commonly smokers and HCV-coinfected. Irrespective of origin, LBP plasma levels were positively correlated with I-FABP (r = 0.467, p = 0.004) and sCD14 levels (r = 0.312 p = 0.060). Significantly higher levels of sCD14 (1885 vs. 1208 ng/mL, p = 0.005) LBP (28.5 vs. 25.3 µg/mL, p = 0.050) and I-FABP (573.4 vs. 358.2 pg/mL, p = 0.002) were observed in European compared with African women. A multivariable linear regression analysis, adjusted for smoking and HCV coinfection confirmed the association between sCD14 levels and women provenance (p = 0.03).

Conclusions: Our observations indicate significant differences in soluble markers among women of different provenance. In the design and analysis of studies evaluating MT markers, population-specific reference values should be considered.
Chemical composition and antibacterial activity of essential oils against pathogens often related to cattle endometritis
Authors: Braga Paiano Renan , Bonilla Jeannine , Moro de Sousa Ricardo Luiz , Micke Moreno Andrea , Sampaio Baruselli Pietro
Published: March 2020

Introduction: Endometritis is a condition marked by inflammation of the endometrium that affects dairy cows from 21 days after parturition, causing damage to herd fertility and economic losses on farms. The use of active compounds obtained from plant sources has gained importance as disease treatment agents in farm animals due to the high resistance rates currently observed against traditional antibiotics commonly used. The study was carried out to examine the chemical composition and to investigate the antibacterial activity of rosemary, cinnamon, cloves, eucalyptus, lemon, oregano and thyme essential oils against the reference strain of Escherichia coli (ATCC 25922), Fusobacterium necrophorum (ATCC 25286), Trueperella pyogenes (ATCC 19411) and Staphylococcus aureus (ATCC 29213), considered as typical bacteria causing endometritis.

Methodology: The chemical composition of the seven essential oils were analyzed by GC-MS and their antibacterial activity was evaluated by the disc diffusion method.

Results: Thirty-six components were identified in total using GC-MS analyzes. The main compounds were cinnamaldehyde (86.5% for cinnamon essential oil), eugenol (85.7% for clove essential oil), 1,8-cineol (80% for eucalyptus and 47.8% rosemary essential oils), limonene (65.5% for lemon essential oil), carvacrol (72.1% for oregano essential oil) and thymol (48.8% for thyme essential oil). The disc diffusion assay revealed that cinnamon, clove, oregano, and thyme essential oils showed the best results compared to the other three essential oils, showing the largest zone of inhibition against all bacteria evaluated.

Conclusions: These findings indicated that essential oils are a potential agent to be used as an alternative for bovine endometritis treatment.
Combien d’orphelins en France ? Dans quelles familles ?
Authors: Flammant Cécile , Pennec Sophie , Toulemon Laurent
Published: March 2020

En confrontant plusieurs méthodes et sources de données, nous estimons le nombre d’orphelins de moins de 25 ans en France en 2015 entre 600 000 et 650 000, dont 250 000 à 270 000 mineurs. Presque trois orphelins sur quatre sont des orphelins de père dont la mère est vivante. Un peu plus de 9 orphelins sur 10 vivent avec leur parent vivant, bien souvent dans une famille monoparentale. Sur le plan social, les familles des orphelins sont plus à risque que les autres familles d’avoir un niveau de vie faible, car elles sont plus souvent monoparentales ou recomposées, mais aussi en raison de caractéristiques sociales du ou des adultes de la famille moins favorables : diplôme plus faible, parent plus souvent inactif, ouvrier ou employé.
Perdre un parent en contexte relationnel difficile : spécificités de l’orphelinage en protection de l’enfance
Authors: Jung Céline
Published: March 2020

Cet article s’appuie sur une recherche dans des services de protection de l’enfance accompagnant des enfants à domicile ou dans le cadre d’un accueil, articulant un volet quantitatif (enquête par questionnaire) et un volet qualitatif (entretiens avec des professionnels et des adolescents). L’enquête confirme que les orphelins sont plus nombreux parmi les enfants protégés en particulier lorsqu’ils sont placés, venant ainsi interroger l’invisibilité de leur situation. Les analyses mettent en lumière tout à la fois les spécificités que recouvre l’orphelinage en protection de l’enfance et les mécanismes de son effacement dans l’accompagnement. Être orphelin et protégé renvoie aussi à la situation sociale des familles, souvent laissée dans l’ombre dans le secteur de la protection de l’enfance.
La statistique internationale comme instrument de globalisation ?
Authors: Renard Léa , Wobbe Theresa
Published: March 2020

Résumé Si de nombreuses études en sociologie historique ont pris pour objet les statistiques publiques et leurs catégories au niveau national, et notamment le rôle des offices de statistiques dans la construction de l’État-nation, les statistiques produites par les organisations internationales, les normes et les représentations du monde qu’elles transportent restent un champ de recherche à construire. De la même manière que les statistiques nationales ont fait de la nation le cadre de référence pour penser les relations professionnelles, nous allons développer dans cet article la thèse selon laquelle les statistiques internationales jouent un rôle primordial dans la construction d’un champ de référence mondial pour appréhender les processus de globalisation du monde du travail. À partir de l’exemple des évolutions de la catégorie des « travailleurs familiaux » au sein des statistiques de l’ oit entre 1919 et 1982, cette contribution met au jour les conditions cognitives et sociales nécessaires à l’émergence d’un cadre de comparaison global.
Un demi-siècle après Pierre Grémion
Authors: Epstein Renaud
Published: March 2020

Résumé Référence obligée des travaux sur l’État et le local, Le pouvoir périphérique n’est généralement mobilisé qu’à titre historique pour prendre la mesure des transformations politico-institutionnelles qu’a connues la France depuis les années 1970. L’analyse de Pierre Grémion est évidemment obsolète dans ses bases empiriques, mais son approche demeure pertinente pour saisir les transformations contemporaines de l’administration et les effets de son désencastrement territorial sur les relations entre pouvoir central et pouvoirs locaux. Telle est la thèse défendue dans cet article qui invite à réopérer un détour par la base pour appréhender les formes renouvelées de la centralisation dans une France décentralisée, qui ne se fondent plus sur la tutelle et l’arrangement mais sur l’autonomie et la mise en concurrence des collectivités territoriales.
Les habitats de défrichement entre Zorn et Bruche (Bas-Rhin) à la période médiévale
Authors: Dottori Boris
Published: March 2020

L’étude des dynamiques de peuplement, de l’habitat et des paysages des secteurs forestiers et montagneux de l’Alsace du second Moyen Âge est une thématique encore peu développée à l’échelle régionale, tant d’un point de vue historique qu’archéologique. Pourtant, ces zones ont, pour cette période, été marquées par un phénomène non négligeable, mais encore relativement mal connu : les créations d’habitats par défrichement. Dans cette contribution, nous abordons le cas des zones de relief et de forêt comprises entre les rivières Zorn et Bruche (Bas-Rhin), pour lequel le croisement de données historiques et archéologiques a permis de révéler plusieurs de ces habitats, attestant une occupation relativement dense de ce secteur entre le XIIe et le XVIe siècle.
Plus belle la campagne
Authors: Modanese Cécile
Published: March 2020

À la croisée de l’étude des paysages (urbains, périurbains, voire des campagnes alsaciennes), des relevés archéologiques, ainsi que des traditionnelles recherches historiques, le travail autour des jardins du XIXe siècle se révèle être une enquête pluridisciplinaire.Souvent étudiés uniquement sous l’angle de leur contenu bâti, les jardins sont en outre composés de végétaux, qui de leur plantation à leur abattage modèlent le paysage. Arrivées massivement durant ce siècle « âge d’or de l’horticulture », les nouvelles plantes originaires du bout du monde, multipliées et acclimatées par des établissements horticoles en émergence offrent de nouvelles formes et de nouveaux coloris aux « dessinateurs de jardins », les paysagistes de l’époque.Le travail s’appuiera sur l’analyse d’une sélection de jardins alsaciens, dont l’aménagement repose sur une utilisation du paysage et de la topographie préexistants.
Changement et innovation en éducation : deux notions en résonance
Authors: Cros Françoise , Broussal Dominique
Published: March 2020

Changement et innovation sont des termes souvent pris l’un pour l’autre. Or il n’en est rien et cette distinction est importante en éducation et en formation, car elle détermine la manière de comprendre l’évolution des systèmes d’éducation et de formation. Cette présentation s’attache à en montrer les différences, aussi bien sur le plan historique que sociétal. Le changement est plus volontiers associé à l’accompagnement, tandis que l’innovation porte sur les contenus de la transformation et ses impacts. La notion de nouveau est toutefois commune et c’est dans le traitement de cette nouveauté et de sa réalisation que se niche une possible comparaison entre les deux termes. Ces deux termes, très employés dans la formation, sont tous deux porteurs de transformations : si le changement se focalise sur l’accompagnement de trajectoires de vies professionnelles, l’innovation comme aventure met plus l’accent sur les effets de changement qu’elle peut produire de manière éphémère ou durablement aussi bien sur les personnes que sur les organisations voire les institutions. Cette contribution est une ouverture à la réflexion mise en œuvre dans les articles de ce numéro thématique de revue.
Accompagner par la recherche le changement des pratiques enseignantes au service de la continuité des apprentissages au cycle 3
Authors: Escalié Guillaume , Legrain Pascal
Published: March 2020

La récente constitution d’un cycle CM1-CM2-6ème appelle un changement des pratiques enseignantes afin d’assurer une continuité des apprentissages des élèves entre l’école élémentaire et le collège. La systématisation de certains « formats pédagogiques » de façon synchronique (entre les disciplines) et diachronique (tout au long du cycle) peut constituer un vecteur de stabilisation des apprentissages dans la transition inter-degrés. A partir d’une conception socioculturelle des processus d’apprentissage-développement, cet article rend compte d’une recherche collaborative visant à accompagner les enseignants d’un réseau école-collège à construire, à partir d’un modèle commun, des dispositifs d’apprentissage coopératif innovants et à les mettre en œuvre en classe. Du point de vue méthodologique, des données qualitatives analysant l’impact de la mise en œuvre de ces dispositifs sur l’activité des enseignants en classe ont été couplées à des données quantitatives visant à examiner les effets de cette démarche pédagogique sur des dimensions psychosociales liées au bien-être des élèves. D’une part, les résultats soulignent l’importance de considérer la mise en œuvre des dispositifs coopératifs dans leurs dimensions à la fois génériques et disciplinaires. D’autre part, ils mettent en évidence des effets significatifs de ce type de dispositifs sur la motivation autodéterminée des élèves. Enfin, des pistes sont tracées pour optimiser la démarche de recherche collaborative ainsi que son impact sur les acquisitions des élèves.
Mise en place d’un dispositif de formation hybride : une innovation c'est un changement qui a réussi ?
Authors: TALI Fatiha
Published: March 2020

Dans cette revue thématique sur l’innovation, notre article a pour objet l’étude des processus mis en œuvre lors d’une innovation pédagogique dans un contexte de formation hybride. À partir d’un cadre théorique référant à l’approche sociocognitive, nous cherchons à voir comment l’agentivité collective pourrait être un moteur de l’innovation. Pour cela, dans une première partie le cadre théorique permet d’aborder les processus liés à l’élaboration d’un dispositif hybride de formation ainsi que l’agentivité collective. Dans une seconde partie, le cadre méthodologique lié à l’étude d’un cas concret de processus d’innovation est décrit avec à la fois la démarche de recherche et la démarche d’ingénierie pédagogique mise en œuvre. La troisième partie permet de présenter les résultats relatifs aux changements sur trois volets : les modalités de formation, les pratiques institutionnelles et les modalités d’apprentissages des apprenants.

Les professionnels de la santé et du social sont amenés à interagir avec des populations très diverses (âge, origine géographique, langue, religion, état de santé, milieu socioéconomique, etc.), ce qui peut venir modifier la façon d’intervenir. La présente étude vise à explorer la perception des étudiants en ergothérapie et en travail social quant au développement de leurs compétences interculturelles, incluant les stratégies mises en œuvre pour travailler harmonieusement avec un individu porteur d’une différence significative. Quarante-six personnes ont participé annuellement à un entretien durant leurs trois années de formation. Sur la base du modèle d’apprentissage transformateur, une analyse thématique a permis d’identifier sept thèmes évoqués par les participants à ce sujet, soit : 1) identifier les apprentissages et les éléments à améliorer ; (2) consolider sa confiance en soi ; (3) utiliser efficacement les techniques de communication ; (4) faire face à l’agressivité ou à des idées divergentes ; (5) connaître et s’adapter à l’Autre ; (6) intégrer et appliquer les connaissances théoriques ; (7) être capable de se remettre en question. Des recommandations pour la formation sont formulées.

Authors: Amathieu Jérôme , Chaliès Sébastien
Published: March 2020

Cet article s’efforce de questionner la possible intégration théorique des concepts de « changement » et d’ « innovation » dans le cadre d’un programme de recherche mené en anthropologie culturaliste et principalement inspiré de la philosophie analytique de Wittgenstein (2004). Par voie de retour, il étudie le caractère heuristique de cette intégration du point de vue du développement du programme de recherche.L’article se structure autour de trois parties. En première partie, les différents niveaux d’intégration des concepts de « changement » et d’ « innovation » au sein du programme sont explicités. En deuxième partie, une illustration empirique de cette intégration est proposée. Enfin, en dernière partie, une discussion est menée autour du travail d’hybridation conceptuelle réalisée et des précautions à envisager pour qu’il soit scientifiquement valide.
The Theoretical Framework of LEAD
Authors: Palazzolo Alyssa N. , Pizzo Dana L.
Published: March 2020

The L.E.A.D. Program provides many learning opportunities for teacher candidates in supporting in-risk youth in elementary and secondary schools. Within the course, there are theories and perspectives explicitly taught through presentations, workshops, and activities, which include: risk and resiliency, strengths perspective, and teaching personal and social responsibility (T.P.S.R.). There are also the theoretical underpinnings that make up the pedagogical strategies employed by the course as well as the structure of the field placement component. This chapter brief explains these important theories as well as an explanation of their importance in the L.E.A.D. Program.
Elementary Service-Learning Project Example
Authors: Palazzolo Alyssa N. , Pizzo Dana L.
Published: March 2020

Every year, the L.E.A.D. program requires teacher candidates to plan and implement a Service Learning Project that meets a need in his or her placement school. The progression of the projects has been outlined in Chapter X. This chapter includes an example of a Service Learning Project implemented at a local elementary school by two L.E.A.D. teacher candidates: Kaitlynn Dunn and Katie Polkosnik. The idea to combine mathematics and mindfulness came from their own observations of the school, conversations with staff and administration, and a review of the school's EQAO scores, school improvement plan, and school climate survey.
Hellison's Teaching Personal and Social Responsibility
Authors: Essery Ryan
Published: March 2020

Hellison's framework provides teachers with instructional strategies, program/lesson structure, individual goal-setting opportunities, and assessment strategies to tap into students' personal and social values and responsibilities. To support L.E.A.D. teacher candidates with teaching personal and social values and responsibilities in their practical teaching, L.E.A.D. teacher candidates are given training on T.P.S.R. This chapter explains how to implement this framework to teach personal and social responsibility, and includes future recommendations.
Application
Authors: Semus Aerin , Essery Ryan
Published: March 2020

During the initial years of the L.E.A.D. program, one of its core values was to incorporate Outdoor and Experiential Education (O.E.E.) for students identified as ‘in-risk' of not graduating. Teacher candidates at the University of Windsor enrolled in the L.E.A.D. program were encouraged to embrace O.E.E. to assist students in building skills that promote overall personal and social development. A major component of the L.E.A.D. program was for teacher candidates to plan O.E.E. activities such as a 3-day overnight camping excursion and a retreat to the Ojibway Nature Centre and Ojibway Park. Embarking on these O.E.E. activities with selected secondary school students deemed to be ‘in-risk' accompanied by a group of caring adults provided the opportunity for rich outdoor experiences for all participants. This chapter highlights and explores the various O.E.E. activities experienced by L.E.A.D. teacher candidates and L.E.A.D. program students ‘in-risk', and shares research that describes the benefits of participation in O.E.E.
People First, Students Second
Authors: Teeuwen Justin
Published: March 2020

The L.E.A.D. program involves teacher candidates collaborating with schools in the delivery of leadership programming for at-risk youth. Compulsory to their learning throughout the program, teacher candidates learn about various topics regarding support for at-risk students' wellbeing. This chapter presents an intervention for supporting at-risk youths' overall wellness which could be integrated within a L.E.A.D. practice. Previous interventions targeting social-skills and self-regulatory behaviour for at-risk elementary students increased academic achievement. Given the interrelationship between emotion and cognition, a “metawellness” intervention that employs metacognition and metaemotion, directed to the six domains of wellness (i.e., physical, emotional, social, intellectual, occupational, spiritual) is proposed for educators to apply to at-risk learners. Hypothetical cases are examined to illustrate potential pathways for, and benefits of, implementing the intervention with at-risk learners. Limitations and recommendations for the present intervention are included.
Designing Effective International Community Service-Learning Experiences
Authors: Beckford Clinton
Published: March 2020

International community service-learning has become increasingly accepted as an effective approach to promoting global education and intercultural knowledge among post-secondary students. Professional schools have been at the forefront of this trend, pioneered perhaps by medical schools. Today, university faculties of education and teacher education programs more generally, are now leaders in advancing ICSL pedagogies. There is now overwhelming evidence that ICSL experiences that are well planned and implemented can be transformative on personal and professional levels. This chapter discusses how effective ICSL experiences can be effected. Drawing on qualitative research from an ICSL for pre-service teachers, the author offers some suggestions for increasing the impacts of such programs.
Teachers as Counselors
Authors: Salinitri Dina
Published: March 2020

The changing demographics and necessary pedagogy of the 21st-century schools require teacher education programs to examine their connection to practice in the K to 12 education system. This chapter focuses on the need for teachers to understand the place of guidance and career education in their curriculum and in the lives of all their students. There are nine Guidance and Curriculum courses offered in all Ontario secondary schools, yet, little is done to provide professional development for teachers to build efficacy for these courses. Faculties of Education spend little time looking at the curriculum expectations in these courses as they are not considered methodology or foundation courses. A comprehensive course developed at the Faculty of Education, University of Windsor, provides teacher candidates with the knowledge and skills to explore these courses and engage in an integrated guidance and career program.
LEADing From Behind
Authors: Salinitri Geri
Published: March 2020

In this chapter, implicit leadership theories are addressed and discussed in the role of a classroom teacher. Teacher Education programs explore the theories and programs like L.E.A.D. that is experiential and takes that theory to practice. Highlighted are the instructional leaders' styles of transformational, influential, distributive with a focus on servant leadership that models the role that works within classrooms, especially those with in-risk youth. Teachers can be change agents in this climate of social justice and inclusion.
Veco-Taxis as a Novel Engineered Algorithm for Odor Source Localization
Authors: Gaurav Kumar , Kumar Ajay , Dayal Ram
Published: March 2020

Algorithms with limited intelligence are unable to localize an odor source in an indoor environment with weak or no airflow. Stage wise solutions to odor source localization has been provided with a novel engineered algorithm called veco-taxis for plume traversal. It finds turn angles by calculating concentration gradients using vector algebra-based search algorithms. Levy walk is used in the plume finding phase. The concept of last chemical detection points (LCDPs) has been adopted for source declaration. The success rate of implemented algorithms is quantified using minimum and maximum move lengths—a key parameter—during source localization. A unified success and performance index (SPI) of the search algorithm is presented for the first time. SPI uncovers implicit parameters accountable for success in locating source and considers a qualitative performance. Higher SPIs are observed when the move length in plume finding is minimum and kept smaller than the plume traversal move length by some factor. It has been also demonstrated through simulations that veco-taxis is superior to the E. coli algorithm.

Authors: Sharma Meenakshi , Thind Sonia
Published: March 2020

In order to protect and secure the sensitive data over the internet, the current data security methods typically depend on the cryptographic systems. Recent achievements in quantum computing is a major challenge to such cryptography systems. In this way, the quantum key distribution (QKD) technique evolves as a very important technique which gives un-conditional data security. This technique is based on the laws of quantum physics for its security. This article gives a detailed description of the QKD technique. This technique secures the encryption key delivery between the two authenticated parties from the unauthorized access. In the next phase, quantum cryptography model is discussed. Finally, some important application areas and limitations of this technology are be discussed.

This article will also give a brief introduction about the various supervised ML techniques such as classification, regression, and unsupervised machine learning techniques such as clustering, etc., which are very useful in analysing the web network so that user can make quick and effective decision making
Combined Learning Models Based on Constructionism Applied in Modern Learning of Biology
Authors: Mariana Iancu M.
Published: March 2020

The purpose of this research has been to identify modern and effective learning models, based on constructionism, in learning biological concepts. The author shows that the cognitive, formative, and emotional benefits, of combined learning models to obtain the best results in the construction of concepts, by students' effort, in accordance with Papert's constructionism ideas. The researcher recommends using the techno-empirio-psycho-sociocentric (TEPS) combined model, based on information and communication technologies (ICTs), in individual-and team-based rediscovery of new biological concepts. When no ICTs are used, the empirio-psycho-socio-centric model is recommended. As an alternative or in combination with, these learning models, the researcher promotes the techno-logo-psychocentric (TLP) model in presentations of science as a finished product when ICTs are used or the logo-psychocentric modernized (LPM) model, with attractive procedures, without ICTs.

Authors: Costello Robert , Lambert Murray
Published: March 2020

The present research develops and tests a theoretical gamification model (GM) that explores the use of mobile learning (ML) and massively multiplayer online (MMO) games to strengthen group prospection of teams and improve retention. The GM used Pokémon GO to enable higher education students to engage in activities and challenges with a view to observe the impacts on health and wellbeing through collection of quantitative and qualitative data. The data that was collected involved a sample set (N = 50) of participants within the general educational sector. The model constructs were measured throughout the first academic semester, from September 2018 to February 2019. There is significant evidence to show that the use of ML in the classroom is beneficial depending on the influences from and engagement with participants. The contributions from these findings should provide the basics for further research into different studies involving MMOs and ML or gamification studies.
