Analysis of the influence of residual stresses on possible defects formed during production of carbon-epoxy composites
Authors: Бондарчук Дарья Александровна , Федулов Борис Никитович , Ломакин Евгений Викторович
Published: December 2020

В настоящей работе изучено влияние наличия остаточных напряжений в образце углерод-эпоксидного композита, сформировавшихся в процессе его производства, на такие возможные дефекты как межслоевое расслоение. Исследование посвящено анализу НДС в регулярных образцах вблизи зоны дефекта в течение цикла отверждения, а также при образовании свободного края в материале после разреза в зависимости от длины трещины. Для моделирования процесса отверждения решалась связанная тепловая и прочностная задача в условиях плоской деформации. Для описания поведения композитного материала в процессе производства, включая процессы формования, полимеризации, развития остаточных напряжений и деформаций, была разработана и реализована специальная пользовательская подпрограмма для ПО ABAQUS. В частности, в данной работе была проанализирована история величин скоростей энерговыделения в режимах раскрытия трещины по механизму нормального отрыва и поперечного сдвига в процессе полимеризации и последующего разрезания с образованием свободного края. Обнаружен незначительный рост значений GI , GII в вершине трещины в процессе полимеризации и многократное превышение этих значений после механического среза. В результате численного моделирования выявлено, что остаточные напряжения не оказывают существенного влияния на рост дефекта в композите на этапе его изготовления, но при приложении дальнейшей нагрузки на образец могут способствовать интенсивному росту расслоения.

In the present study, the effect of presence of residual stresses inherited during manufacturing on delamination defect in carbon-epoxy composite specimen is investigated. The research is devoted to understanding of strain-stress state in regular specimens near defect zone during cure cycle and after free edge cut depending on crack length. To describe the behavior of the composite material during manufacturing process- including processes of formation, polymerization, development of residual stresses and strains, the special user subroutine was developed and implemented in ABAQUS FEM software. The history of energy release rates under mode I, II ( GIc , GIIc) where analyzed over time during process of polymerization and free edge cut. A slight increase in the GI and GII values at the crack tip during polymerization and a multiple excess of these values after a mechanical cut is shown. Obtained by modelling values for stress components are essential and cannot be ignored in consequent structural analysis. The results of the study can be applied for prediction of residual stresses in composite structure by means of simulation and further understanding the nature of fracture of composites.

Рассмотрена задача продольного растяжения двухслойных пластин из гексагональных и кубических кристаллов при различной ориентации слоев. Получены аналитические зависимости модуля Юнга и коэффициентов Пуассона пластин от отношения толщин. Проведен численный анализ изменчивости эффективных характеристик пластин из всех возможных комбинаций гексагональных и кубических кристаллов. Установлено, что существенное нарушение правила смесей для эффективного модуля Юнга двухслойной пластины происходит, если один из двух слоев заполняет ауксетик. Эффективный модуль Юнга может превосходить модули Юнга кристаллов в обоих слоях близкой жесткости. Отношение модулей Юнга кристаллов в обоих слоях оказывает существенное влияние и на эффективный коэффициент Пуассона.

The problem of longitudinal tesnsion of two-layered plate of hexagonal and cubic crystals with different orientations of crystallophysic coordinate systems is discussed. Analytical dependences of effective Young’s modulus and Poisson’s ratios on layer thickness ratio are obtained. Numerical analysis of plates from all possible combinations of hexagonal and cubic crystals is performed. It is established that significant deviation of effective Young’s modulus values from predictions by mixture rule takes place in the case when one of the layers is auxetic. Effective Young’s modulus can have greater value than values of Young’s modulus of crystals at both layers. The ratio of Young’s modulus of crystals has great influence on the value of effective Poisson’s ratio.
Dragojla, Ivana, Mani – subverzija kao dijalog?
Authors: Odža Ivana
Published: December 2020

U radu se razmatraju dnevnički zapisi dviju hrvatskih autorica, Dragojle Jarnević
(1812. – 1875.) i Ivane Brlić-Mažuranić (1874. – 1938.) te autobiografski roman
Fališ mi u proljeću, u jeseni, u ljetu, u zimi, Mani Gotovac (1939. – 2019.). Navedena
djela svojim poetičkim obilježjima, u širokom smislu riječi, slijede matricu ženskog
pisma, nerijetko obilježenog iskustvom traume. Trauma se često manifestira
autodestruktivnošću književnog subjekta iskazanom na dvama načinima:
specifičnom uporabom jezičnih elemenata i/ili, na sadržajnoj razini teksta,
eksplicitnim govorom književnog subjekta o vlastitim autodestruktivnim porivima,
potaknutima nemogućnošću uspostavljanja zadovoljavajućeg odnosa s važećim
društvenim paradigmama – obuhvatit ćemo ih simbolično nazivom ‘autoriteti’. Uz
pretežno subverzivan odnos prema autoritetima, što rezultira autodestruktivnošću
književnog subjekta, uočljiv je u Jarnević i Brlić-Mažuranić, obrnuto recipročan odnos
između dinamike izražavanja autodestruktivnog i uvažavanja metafizičkog kao
jednog oblika autoriteta. Kod Gotovac je odnos prema metafizičkom drukčiji u odnosu
na njezine prethodnice, riječ je o svojevrsnom modelu »doživljaja vjere u nevjeri«
(Šimundža). Cilj je rada: (1) razmotriti različite manifestacije autodestruktivnoga u
književnih subjekata, (2) razmotriti odnos autodestruktivnog i metafizičkog te (3)
otvoriti mogućnost drukčijeg iščitavanja subverzivnog elementa ženskog pisma
razmatranjem pitanja može li se subverzivan odnos prema autoritetima promatrati
kao latentna tendencija prema uspostavljanju dijaloga s njima.

Authors: Škifić Sanja , Grbas Katarina
Published: December 2020

Imigracija u Irskoj, uključujući imigraciju Hrvata u tu zemlju, u posljednje vrijeme u
znatnom je porastu. Stoga Irska u posljednjih nekoliko godina nastoji pronaći načine
na koje se imigrantima može osigurati odgovarajuća kulturna i jezična integracija
u irsko društvo. Ovaj rad se bavi istraživanjem jezične uporabe i stavova hrvatskih
imigranata u Irskoj. U istraživanju koje je provedeno od lipnja do kolovoza 2019.
godine sudjelovala su 82 hrvatska imigranta u Irskoj. Za potrebe istraživanja korišten
je upitnik koji se sastojao od četiriju dijelova i koji su ispitanici ispunjavali preko
društvene mreže Facebook. Od ispitanika se tražilo da odgovore na pitanja vezana za
vlastito iskustvo emigracije u Irsku, a većina jezičnih pitanja odnosila se na engleski,
i to na pojedine aspekte učenja, razine poznavanja i uporabe engleskoga jezika u
različitim kontekstima. Rezultati istraživanja pokazuju, između ostaloga, da većina
ispitanika ima pozitivan stav prema boravku u Irskoj te engleskome jeziku. Većina
njih procijenila je svoju trenutačnu razinu znanja engleskoga jezika mnogo boljom
od prosjeka. Iako znanje engleskoga jezika većinom nije procijenjeno ključnim
za pronalazak posla u Irskoj, ipak ga je značajan broj ispitanika procijenio bitnim
prilikom njihova zaposlenja.
A 2020. év tapasztalatai, az új ombudsman első éve
Authors: Dános Valér
Published: December 2020

The Parliament elected Dr. Ákos Kozma in a secret voting, by votes of more than two-third of the representatives, to commissioner of fundamental rights for a six-year period on 2nd July 2019. He was previously the deputy chairman of the Independent Police Complaints Body. He took over his office from his ancestor on 26th September 2019. At his election he formulated in his programme that he intends to be an ombudsman for everybody, puts special emphasis in his future work on protection the rights of children and handicapped people and intends to inform the wider public about his official work. In the period passed until now his ideas seem to be realised. The already complicated works of an ombudsman were even extended after 27th February 2020, when the Independent Police Complaint Body ceased working, as examination of police complaints became part of the work of the commissioner for fundamental rights, too. The Hungarian ombudsman also joined actively the international professional life through several forums. The consequences of the coronavirus pandemic met the official activity of the commissioner for fundamental rights, too. How it was experienced in the everyday work, how the diversified field of duties could be complied with, which are the experiences of the first year – Dr. Ákos Kozma, commissioner of fundamental rights, was asked by Dr. Valér Dános, editor-in-chief.

Espace du rêve, espace de la séance
Authors: Bleger Leopoldo
Published: December 2020

Freud n’a pas cessé de traquer un acte dans les temps premiers de la vie de ses patients comme dans la vie de l’espèce humaine. Cela tient, en partie, à la conception que le livre sur le rêve, la Traumdeung , apporte au tout début de son œuvre : le rêve comme circuit court de décharge, c’est-à-dire d’action. Dans l’espace de la séance, le rêve est un fragment d’action, il « fait » quelque chose autant à l’analyste qu’au patient. On peut dès lors interroger la tendance à faire du rêve lui-même un espace riche d’expérience. Le risque est de revenir à une surestimation du rêve au détriment de l’espace de la séance.
Le rêveur à son métier
Authors: Rolland Jean-Claude
Published: December 2020

L’auteur recense les fonctions accomplies par le rêve, telles : la remémoration des traces mnésiques infantiles qu’il tisse aux restes diurnes pour en faire des souvenirs ; la désexualisation de la charge œdipienne de ces formations inconscientes autorisant le renoncement aux objets primaires ; la réorganisation de l’espace psychique grâce à la redistribution des domaines impartis à l’inconscient et au préconscient et à la création d’une « autre scène » propre à la représentation de la vie fantasmatique ; le désendeuillement des morts aimés laissés dans l’esprit par l’histoire individuelle aussi bien que phylogénétique du rêveur. Ce travail « physique » réalisé par le processus du rêve justifie sa comparaison avec celui du tisserand. Freud en emprunte la métaphore à Goethe qui y recourut pour se familiariser avec la fabrique de la pensée en général.
Le rêve bâtard des philosophes antiques
Authors: Schniewind Alexandrine
Published: December 2020

Cet article explore le statut du rêve dans l’Antiquité grecque, de Homère à Augustin. Le rêve est d’abord compris comme un message divin, puis est perçu comme une production de l’homme, à la frontière entre la sensation et la pensée. L’approche philosophique du rêve, dans l’Antiquité, a cela de novateur qu’elle permet de s’approprier le rêve comme un phénomène intrapsychique.

¿“Crowdfunding” como finanzas democráticas? Comprender cómo y por qué los inversores del Reino Unido confían en estos mercados
Authors: Davis Mark , Braunholtz-Speight Tim , Wardrop Robert
Published: December 2020

¿Puede el crowdfunding contribuir al reequilibrio del sistema financiero mediante la democratización de la inversión? Este documento comienza a responder a esta pregunta estableciendo cómo y por qué los inversores confían en estos mercados. Ofrecemos dos contribuciones. Primero, a los debates teóricos sobre finanzas democráticas; y segundo, a un cuerpo más empírico de investigación interdisciplinar sobre inversión popular a través de un análisis cualitativo de 52 entrevistas originales con inversores en seis mercados de crowdfunding del Reino Unido. Nuestros datos se toman de un proyecto con la Autoridad de Conducta Financiera del Reino Unido para mejorar la protección de los inversores en estos mercados. Utilizando un enfoque de sociología económica, encontramos que los inversores: movilizan redes integradas para establecer confianza en el crowdfunding; están motivados por las expectativas de «rendimientos combinados»; prefieren herramientas de inversión automatizadas si carecen de experiencia; y típicamente invierten con fondos que han destinado a perder. Concluimos que se requiere una mayor protección de los inversores para la financiación colectiva para ayudar a democratizar las finanzas

There is no doubt that the present atmosphere has been no picnic for educational establishments, causing it almost difficult to keep on to work while holding fast to social removing and guaranteeing the security of students or learners and staff. This paper advocates the new ordinary as one of the key triggers of the new educational revolution. It contends that the Covid-19 crisis has compelled education foundations to rethink their model for passing on education in a worldwide society where mobility or movements of individuals are sincerely under peril. Past this contention, its discoveries explain the hidden variables of an educational revolution since the declaration of the second educational revolution 10 years prior. This investigation has furthermore worried on why leaders of education systems and organisations should absorb the new ordinary, aftereffect of the overall pandemic particularly, thinking about the extent of point of reference occasions to date. The author along these lines thinks the new typical will compel people to re-examine as the dangers control decisions have driven a colossal number of learners into brief "self-educating" conditions and others related circumstances, which have included the reason dispute of this paper.

Therefore, an accurate lung segmentation system from CT image based on proposed CNN architecture is proposed. The system used weighted softmax function the improved the segmentation accuracy. By experiments, the system achieved a high segmentation accuracy 98.9% using LIDC-IDRI CT lung images database.
Automotive Radar using AWR2243 Booster Pack
Authors: Vishnubhatla Arvind
Published: December 2020

In developing countries the growth in the number of motor vehicles is the most significant factor in the rise of road fatalities and injuries. It may be observed that 1.35 million people die every year owing to crashes on road. Most of the accidents can be prevented if the events are detected automatically 1-2 seconds in advance. Texas instruments has come up with a new evaluation board AWR2243 having a single chip operating at 76 to 81Ghz having a FMCW transceiver. This can be instrumental in adaptive cruise control, emergency braking and automated highway driving. A FMCW (frequency modulated continuous wave) obtains the range and velocity from a beat signal. Here millimeter-wave sensors use minimal power consumption to sense range and velocity and the required angle.  The device is interfaced to an external DSP host processor which uses a SYNC_IN signal to start the radar frames. The periodicity of the frames is suitability programmed. The processing provides a high level of performance and flexibility. The signal has three parallel transmit chains and four parallel receive chains. Each receive channel has an LNA, mixer, IF filtering, A2D conversion and decimation. A two- dimensional FFT algorithm is implemented on the host DSP processor.
How does Legalization alter Islamists’ Electoral Strategies? A Comparative Study of Mauritania’s Tawassoul Party in the 2006 and 2013 Local Elections
Authors: Buehler Matt
Published: December 2020

Cette étude examine le parti islamiste de Mauritanie, le Rassemblement national pour la réforme et le développement (Tawassoul), ayant présenté des candidats aux élections locales de 2006 et 2013, respectivement en tant que parti interdit et parti autorisé, après sa légalisation en 2007. Se basant sur des données collectées sur le terrain en Mauritanie et sur des entretiens avec des personnalités politiques du parti Tawassoul, cette étude compare les changements de stratégie électorale des islamistes entre leurs périodes d’illégalité et de légalité. En tant que parti interdit en lice lors des élections de 2006, les islamistes mauritaniens se sont concentrés sur la présentation de candidats dans les districts de leurs soutiens traditionnels, les électeurs urbains et religieux. Cependant, une fois le parti légalisé, ses candidats aux élections de 2013 se sont moins concentrés sur les zones urbaines et ont tenté d’obtenir un ancrage politique dans les districts ruraux. S’il est difficile de déterminer précisément pourquoi les islamistes ont décidé de faire campagne de façon moins exclusive dans les zones urbaines, on peut toutefois penser qu’ils ont cherché à s’attirer le soutien de groupes sociaux marginalisés dans les zones rurales, particulièrement les électeurs haratines.
L’ayant droit : un droit de cité et d’être cité dans la vie villageoise en Kabylie
Authors: Mohand Akli Hadibi
Published: December 2020

Le texte tente de répondre à quelques questionnements autour de la notion d’ayant droit, vocable utilisé particulièrement dans la littérature juridique de l’ethnologie coloniale. Nous sommes partis d’événements a priori mineurs qui se sont déroulés dans un petit village de la Kabylie de la Soummam depuis 1993 pour y analyser les dynamiques de recompositions sociales et statutaires sous-tendues par les enjeux de citoyenneté locale. La contribution tente de montrer comment cette dynamique fait appel à des registres multiples de légitimation qui restent indissociables d’une trame historique. L’observation d’une série d’initiatives publiques des individus et des familles en lien avec leurs conceptions de ce qu’est le bon exercice de leurs droits montre que leur reconnaissance n’est jamais totalement définitive, car régulièrement mise en question en fonction des contextes historiques et des rapports de force au village.
Les ittifâq-s communautaires. Escamotage d’archives et autonomie locale dans la province de Tunis au XIXe siècle
Authors: Bargaoui Sami
Published: December 2020

L’auteur examine dans ce travail un lot d’archives tunisiennes de l’époque moderne, non répertorié et jamais mis à la disposition des chercheurs. En se penchant sur les processus de production et d’archivage de ces documents – des attestations d’élection (ittifâq-s) à des offices publics dans les communautés locales mobilisant souvent de très grandes parties des hommes – il remet en cause le regard dominant dans l’historiographie de la province qui, en adoptant un point de vue étatique, amplifie beaucoup la réalité de l’hégémonie du pouvoir central et minimise le rôle des agents locaux. L’invisibilisation de ces archives a participé à la construction de l’image d’un État territorial et national que s’est construit par la dissolution des pouvoirs locaux et l’avènement d’un sujet politique « moderne », alors qu’en fait les communautés locales se sont intégrées dans le corps politique global tout en gardant une autonomie relative qui leur permet au moins de choisir par eux-mêmes en grande partie ceux qui les gouvernent sur les lieux où ils vivent.
Jews, Rights, and Belonging in Tunisia: Léon Elmilik, 1861-1881
Authors: Marglin Jessica M.
Published: December 2020

À partir du cas de Léon Elmilik, un juif algérien qui a fait carrière en Tunisie au XIXe siècle, cet article propose une lecture de la citoyenneté au-delà de son statut formel, celui centré sur le statut accordé aux citoyens au sens juridique. Elmilik a d’abord oeuvré avec des juifs et des chrétiens, unis dans un même but : celui de moderniser et d’occidentaliser la Tunisie. À cette fin, il a participé au comité local de l’Alliance israélite universelle, écrit dans un journal juif publié à Paris, et a été membre d’une loge maçonnique locale. Dans tous ces modalités d’actions, il joignait sa voix à celle des Européens qui critiquaient les abus commis sur les juifs par les autorités tunisiennes. Mais après avoir accepté un emploi de fonctionnaire en 1873, Elmilik a commencé à défendre le traitement des juifs par l’État tunisien. Loin de présumer qu’Elmilik était un opportuniste, je soutiens dans ce travail que ses engagements distincts, et parfois opposés, représentaient les répertoires multiples dans lesquels les juifs situaient leurs droits ; puisque les droits étaient centraux dans la construction de l’appartenance, le questionnement des différents registres de droits auxquels les juifs faisaient appel offre une vue des multiples niveaux d’appartenance cultivés par les juifs et les musulmans du Maghreb pré-colonial.
La construction d’une discipline universitaire : la génétique à la faculté des sciences de Paris de 1946 à 1970

Published: December 2020

L'accession de la génétique au rang de discipline enseignée à la faculté des sciences de Paris en 1946 est liée à l'attribution de la première chaire universitaire de génétique à Boris Ephrussi. Au milieu du XXème siècle, les professeurs Boris Ephrussi, Philippe L'Héritier, Georges Teissier et Georges Rizet, puis Piotr Slonimski et Madeleine Gans, ont été les initiateurs d'une pédagogie novatrice appuyée sur une recherche scientifique originale. Durant les décennies suivantes, les progrès de la recherche ont entrainé des remaniements importants de l'enseignement mais le lien organique entre recherche et enseignement s’est toujours maintenu.
Sorry it took me so long: Latin America and rapid governments’ response to COVID-19
Authors: Rebouças Batista Ian , Domingos Amanda , Lins Rodrigo
Published: December 2020

When facing the COVID-19 pandemic, what was key to governments’ response velocity throughout Latin America? The region had more information on what to do to prevent the disease from spreading itself and social isolation was the most recommended measure to avoid contamination. Still, Latin American countries varied greatly on how fast they adopted strict social isolation measures. We deploy an explanatory work on which institutional designs collaborates with higher delay in governments’ adoption of these measures. Among the institutional variables considered, we find that our variable of interest (delay) correlates strongly and positively with democracy, negatively with concentration of power, and positively with GDP per capita. These might suggest that autocrats faced less institutional and moral constraints to act, while democratic leaders dealing with pluralism and accountability faced higher costs to implement such measures. Due to the small sample, we next investigate  ’ experience looking for examples for the found correlations.Keywords: Government’s delay; COVID-19; Political Institutions
Internet Information Monitoring System
Authors: Primo Paola Pinheiro Bernardi , Antunes Michele Nacif , Ramos Mariela Pitanga , Siqueira Carlos Eduardo Gomes , Oliveira Adauto Emmerich , Mendes José Manuel
Published: December 2020

This study presents an information monitoring system: SIGDesastre. It is a method of monitoring the various sources of information available on the internet. The monitoring scenario is the failure of the dam in Mariana, Brazil. This event was considered the biggest socio-environmental disaster in the country. The creation of SIGDesastre involves the identification of the sources to be monitored, an automated search system for keywords in these pre-registered sources and the visualization of the results in a friendly environment. The use of information monitoring on the internet is considered an important tool for the post-disaster risk communication process. The monitoring of information on the internet is believed to be a potential device to support managers in institutional decisions and in the formulation of public policies. Also, for the affected population, they will be able to expand access to information about the actions being taken by the actors involved.
Views From Parents of At-Risk Students in Singapore Towards the Use of Fun Design-and-Make STEM Projects to Foster Creativity and Joy of Learning
Authors: Amir Nazir
Published: December 2020

This chapter reports the views from parents of 38 students, averaging 13 years of age, in a secondary school in Singapore towards the use of appealing design-and-make toy projects to foster joy of learning and creativity in science amongst their children who are in an academically low achieving group. An instrument to capture the parents' views was developed and administered in a parent-teacher conference (PTC) at the end of the school term. In the PTC, parents and siblings of these students had a chance to look through their design journals and fiddled with their toy inventions. Information gathered from the parents highlight that they value the teacher's approach in motivating and engaging their children to learn science and were impressed with the creativity showcased by their children through the toy projects. Such positive views from the parents affirm the use of appealing design-and-make toy projects to promote interest and understanding in science, as well as foster their creativity and inventiveness in the STEM (Science, Technology, Engineering, and Mathematics) areas.

Authors: Sgoutas-Emch Sandra , Liu Judith , Meyskens Moriah , Salinas Tara Ceranic , Friedman Jane , Myers Perla
Published: December 2020

Cultivating a community of faculty to support Scholarship of Teaching and Learning (SoTL) work at universities can be challenging. There are many obstacles to overcome—obstacles such as how to sustain such efforts over time. The Center for Educational Excellence set out to design a strategic plan designed to address certain barriers to SoTL work and to create a long-standing community of practice for a SoTL group of faculty members—a group that has lasted over nine years to date. This chapter outlines strategies employed over the years and the evolution of the interdisciplinary group from a learning community to community of practice. The stories of past and present members are included along with advice on how others may have successful programs at their universities.
Creating Virtual Communities That Work

Published: December 2020

The use and import of virtual collaboration (VC) has increased at an exponential rate. Despite its potential advantages, however, VC continues to be hindered by feelings of distrust, detachment, and even isolation among virtual team members. For each of these reasons, the present study analyzed more than 1,500 survey responses to develop best practices for current users and developers of e-collaboration software. More specifically, this study used an expanded variation of Vorvoreanu's (2008) Website Experience Analysis (WEA) to explore participants' views of the seven most popular VC programs in use today: Basecamp, Dropbox, Google Drive, iDoneThis, Join.me, Skitch, and Skype. Qualitative results of this study revealed the significance of (1) name recognition, (2) interpersonal facilitation, (3) clarity/simplicity, (4) cost consideration, and (5) mobile accessibility. The study's results were then used to develop five corresponding implications for both users and developers: (1) increased integration, (2) expanded physicality, (3) supplemental training, (4) financial entrée, and (5) utilized flexibility.
Using Communities of Practice to Identify Competencies
Authors: Mupepi Mambo G.
Published: December 2020

While there is currently a significant amount of work being done to promote competency-based education (CBE), many efforts are focused on the design, development, administration, and technology of CBE programs. Yet CBE programs will be successful only if they begin with an accurate and comprehensive identification of required competencies and the key performance indicators (KPI) necessary for effective instructional planning and assessment. This continues to be an area of ongoing debate in competency-based education, particularly in regard to the identification of 21st century competencies and those that reflect higher-order thinking skills. This article suggests that communities of practice (COP) can be integral partners in the effort to identify competencies, establish levels of proficiency that support common divisions of labor within industries, and distinguish the novice from the expert.

Authors: Jacobsen Michele , Friesen Sharon , Brown Barbara
Published: December 2020

In this chapter, the authors present and discuss findings from a two-year case study on teachers' professional learning. This investigation built upon existing research on early learning and technology to study teachers' professional learning in a community of practice, and the development of classroom-based learning designs and the ongoing inquiry of teachers from four school jurisdictions in the province of Alberta in Canada. Focus was on investigating ongoing continuous improvement of teacher design and assessment practices, to identify and share promising practices from the classroom, to capture teacher learning and engagement, to document the appropriate use of technology for learning and to identify and to understand system affordances and constraints for using technology with young learners.
Exploring a Transformative Teacher Professional Development Model to Engender Technology Integration in the 21st Century ESL Language Classrooms
Authors: Lee Kean Wah , James Cynthia C.
Published: December 2020

A 21st century teacher must communicate in the language and style of their students to ensure that their learning is meaningful. However, this is challenging, especially for teachers who are less familiar with using technology in teaching. To inspire a group of ESL ‘digital immigrant' teachers, a professional learning community (PLC) was set up. PLC consisted of both pre-service teachers (digital natives) and in-service teachers (digital immigrants). The two groups exchanged knowledge through a series of sharing sessions to demonstrate the technical aspects of technology, as well as to provide an understanding that technology has affordances and constraints. This case study investigates a group of in-service teachers who adopted the IDDIRR instructional design model (introduce, demonstrate, develop, implement, reflect, revise) to develop technology-based lessons for their ESL classrooms. The data for this study were collected through three main instruments: surveys, interviews and written reflections. The survey data was descriptively analysed using SPSS Version 24, while the reflection and interview data were assessed using thematic analysis. The findings suggest that the IDDIRR-TPACK + PLC model, along with a supportive PLC environment and the presence of more knowledgeable peers (MKO), helped enhance teachers' TPACK and inspired them to integrate more technology in their classrooms.

Authors: Wheat Jennifer
Published: December 2020

Professional learning communities (PLCs) have been implemented in school districts as a means to promote effective instructional policy initiatives and best practices. The purpose of this chapter is to identify assessment literacy commonalities within middle school-level math PLCs and to compare those commonalities across PLCs with different levels of student math growth. Multiple indicators of assessment literacy were used to supply rich descriptions of assessment literacy within each PLC using a procedure recommended by Bernhardt for effective data-driven decision making. Based upon the findings the researcher concluded that commonalities existed among PLCs with different levels of student math growth.

Authors: Muñoz Lilia Esther , Morales Itza
Published: December 2020

The different levels that comprise education seek to adapt techniques, practices, models, and strategies to complement teaching and learning generating knowledge in students; thus, in its different fields, it provides the basis for technology to develop software applications to assist with teaching and learning practices. Consequently, education undergoes rapid changes that influence improvement through the use of some of the tools such as robotics and augmented reality which contribute to improving learning scenarios in students, allowing them to develop their metacognitive skills using technological environments designed to educate and be a medium in the educational process. Therefore, this topic addresses the following study based in the completion of two projects aimed at elementary school students in fundamental subjects, allowing them to become familiar with technology as a means of learning.

Published: December 2020

Psychological capital (PsyCap) is a measure of the positive capabilities of an individual which consists of four components: hope, efficacy, resilience, and optimism. In this study, the pattern of the effect of organizational tenure on the PsyCap of employees in the hospitality and tourism industry was mined. The PsyCap and length of service data of a sample of 329 employees working in some organizations related to hospitality and tourism were collected. The odds ratio was deployed to measure the pattern and strength of association and the findings showed that employees who stay longer years in an organization are 3.6 times more likely to exhibit high PsyCap than those who stay shorter periods. With the positive pattern of this association, it implies that indiscriminate retrenchment of long-serving employees should be avoided to preserve PsyCap within the industry.

Leadership, innovation, and performance are essential factors to achieve the desired sustainable profitability of companies. The relationship between these variables is one of the keys to the organizational success, although their study has proved to be complex. The purpose of this article is to analyse the impact of leadership on the relationship between innovation and performance in the Portuguese hotel sector. To answer to this challenge, a survey was carried out to top and middle managers of four-star and five-star hotel units. The existence of a positive correlation between innovation and performance was found; however, leadership has not been shown to have a moderating effect on the relationship. The work highlights several important contributions to the hotel industry and identifies aspects that, when well implemented and developed, can lead to superior performance in organizations.
Optimization of PCB SI Coupon Design That Minimizes Discontinuity Through via-in-Pad Plated over (VIPPO) Technique

Published: December 2020

The importance of signal integrity is emphasized as signal speed increases, and higher frequencies are applied. The Print Circuit Board (PCB) manufacturer uses signal integrity coupons that can replace the in-product circuit to measure and calculate the signal loss. In this study, we tried to minimize the discontinuous path of Delta-L coupon by using the via-in-pad plated over (VIPPO) technique to improve the signal integrity. We compared the VIPPO-applied design that has minimal discontinuity with the conventional Delta-L design. To minimize discontinuity, circuits connected to pads and via holes were removed from the outer layer, and the pads were designed directly above the via holes. First of all, we simulated the optimized design that eliminated discontinuities using signal integrity software, Simbeor. Second, we measured and verified Delta-L by using Introbotix’s Accu-Prober program. In the future, higher measurement frequencies will further increase signal loss because of unnecessary pathways and discrete signals; therefore, minimizing the effects of discontinuity will be an important issue, and using the VIPPO technique will help improve signal integrity.
Notes on carabid beetles from the Oriental and Neotropical regions. First record of Trechodes laophilus Deuve, 2002 from Thailand (Coleoptera Carabidae Trechinae) and a synonymic note on the genus Trirammatus (Coleoptera Carabidae Pterostichinae)
Authors: Allegro Gianni , Giachino Pier Mauro
Published: December 2020

Trechodes laophilus Deuve, 2002 is firstly recorded from Thailand (Chiang Mai province, Mae lai river). This species is probably closely related to T. leclerci Deuve, 1987 and T. satoi Uéno, 1991, both from Thailand too. An identification key including the morphology of the aedeagus, to all Trechodes species recorded from the Oriental region, as well as a distribution map of the species known so far from Thailand, are provided.Moreover, the following new synonymy is proposed: Blennidus magellanicus Allegro & Giachino, 2017 = Trirammatus unistriatus nocticolor Straneo, 1955 syn. n.

Low vision device requirements among children from two schools for the blind in Tamil Nadu
Authors: John Deepa , Jacob Chris , Paul Padma , Abraham Lekha , Kuriakose Thomas
Published: December 2020

Purpose:

To identify children with low vision from two local schools for the blind, to provide low vision devices (LVD) to those who may benefit from it, and to encourage them to learn print.

Methods:

A prospective study was conducted among children from two local schools for the blind. Best-corrected visual acuity (BCVA) was done using the Snellen chart. Children with BCVA of counting finger (CF) 1/2 meter or more in the better eye underwent low vision assessment. Distant vision was assessed using the Feinbloom chart and near vision was assessed using the Lea symbol chart. Low vision devices (LVD) were prescribed as required.

Results:

Among 185 children enrolled, 31 children had BCVA of >CF ½ meter. Using a telescope, distant vision was better than 3/36 in 48.4%, 3/36–3/12 in 16.2%, and 3/9.5 to 3/3 in 35.4%. Among 23 children who read 1M at <10 cm, 22.6% could read 0.6–0.8M, and 25.8% could read 1M using LVD.

Conclusion:

Regular screening of children in schools for the blind could identify children who might benefit from LVD. A review of protocols for the entry of children in schools for the blind by screening these children by a specialist team prior to admission should be made mandatory.
Validating tablet perimetry against standard Humphrey Visual Field Analyzer for glaucoma screening in Indian population
Authors: Ichhpujani Parul , Thakur Sahil , Sahi Roopjit K , Kumar Suresh
Published: December 2020

Purpose:

The aim of this study was to determine the correlation between the perimetric outcomes using a free application program of the iPad, 'Visual Fields Easy' (VFE), and Humphrey Visual Field Analyzer (HVFA), in normal as well as eyes with glaucomatous damage of varying severity.

Methods:

In this prospective, cross-sectional, observational pilot investigation, visual field testing was carried out in 210 eyes of 210 patients (60 Normal, 150 Glaucoma), using suprathreshold VFE application (Version 8) on the iPad and Standard White-on-White using HVFA. Severity of glaucoma was categorized using Hodapp-Anderson-Parrish criteria for visual field defects. The results of the VFE program were compared to the 24-2 SITA FAST HVFA.

Results:

Data of 210 patients, 100 (47.6%) females, and 110 (52.4%) males, age ranging from 42 to 78 years, Mean 56.64 ± 10.67 years, was analyzed. The Spearman correlation coefficient showed a significant inverse relationship between missed points on the VFE app with MD (S = –0.783) and a parabolic relationship with PSD (S = 0.646) values obtained with the HVFA. As regards missed points, for mild glaucoma, missed points were 37.5, sensitivity was 77.8% and specificity was 52.6%; for moderate glaucoma, missed points were 33.5, sensitivity was 90% and specificity was 48% while for severe glaucoma, missed points were 23, sensitivity was 97% and specificity was 70%. AROC for eyes with mild glaucoma versus normal was 0.419 (95% CI: 0.343-0.495), moderate glaucoma versus normal was 0.705 (95% CI: 0.630-0.780) and severe glaucoma versus normal was 0.857 (95% CI: 0.806-0.908).

Conclusion:

Suprathreshold perimetry using VFE is not suitable as a rapid screening tool for mass screening of glaucoma. VFE cannot be used as a substitute for HVFA in clinic because of its inability to detect early or moderate glaucoma.
