The tourism in the rural zone as instrument of combat to the degradation of the lands in the semi-arid northeastern
Authors: Coutinho Solange Fernandes Soares , Oliveira Neto Antônio Ferreira de , Cavalcanti Edneida Rabelo
Published: December 2022

The tourism is today, thankfully, an important alternative to the economical dynamization of

stagnated areas that have potentiality for its development. Among the different modalities of

tourism, some can, with success, be developed in the rural area - among them the ecotourism

and the rural tourism. Considering that the tourist activities need to promote the

environmental conservation so that the same ones reach its sustainability, once when

degrading the environment in which they happen, they degrade themselves. The objective of

the work is it of evaluating the potentialities for the development of the tourism in the rural

areas as instrument capable to avoid or to minimize the degradation of the lands in semi-arid

environment in the Northeast Region of Brazil, having the environmental education as guide

base of the handling of those activities for the several involved actors. The research focuses

the Poles of Development of Eco-tourism in the area, confronting the socioeconomic realities

to the tourist possibilities offered by the natural resources and cultural patrimonies. It grew

starting from cabinet studies and of field, propitiating the recognition of the discrepancy

among the potentiality for the development of the tourism in the rural area and its occurrence,

demonstrating the divergence among the speech contained in the National Politics of Tourism

and its practice, once this continues to motivate, in different ways, the tourism in the coastal

areas, where they are driven the largest amount of financial investment, so much in infrastructure terms as in training of human resources. But, at the same time, it was also

possible to identify areas where tourist activities are being capable to promote the decrease of

the human pressure on the natural resources, especially in what it concerns to the vegetable

covering and the soil, that promote the degradation of the lands and, in certain cases, the

origin and intensification of the phenomenon of the desertification.
Urbanization and environmental disruption of catchment basins as a result of housing development at Cidade Operária and adjacencies, Maranhão Island
Authors: Sousa Izis Deise Silva de , Veloso Geiza Paula de Sousa , Dias Luiz Jorge Bezerra da Silva
Published: December 2022

The Industrial Revolution was followed by an increase in the rates of urbanization, particularly

after the second-half of the 20th

century. In this context, Sao Luis, the capital city of

Maranhao State, adopted a housing development policy that was aimed at reducing the

housing deficit in the municipality. The construction of the Cidade Operaria housing complex

was a response to these explicit social needs, which have intensified since the 1970s. The

occupation of the complex, however, resulted in considerable damage to the ecological

integrity of the adjacent habitats. The complex is located in the catchment basin of the

Paciencia and Santo Antonio rivers, at the center of the Maranhao Island. This study analyzes

the spatial and temporal dynamics of the area's urbanization process, which occurred in three

phases: the period between 1976 and 1981 saw the removal of the original vegetation cover in

some areas, as a result of the first settlement in Parque Zelandia. During that period,

subsistence agriculture was common practice along the margins of streams and rivers. The

second phase corresponds to the construction of the Cidade Operaria housing complex, which

occurred between 1981 and 1988. During that time, 860 ha of land were cleared and

urbanized, resulting in considerable environmental damage. Changes of relief, due to grading

and earthmoving activities, lead to irreversible modifications in the course of rivers and

streams; many tributaries of the rivers Paciencia and Santo Antonio had theirs springs

smothered by earthfills; construction of houses and the use of asphalt on roads reduced soil

permeability, increasing the depth of the water table; the release of untreated sewage

contaminated the drainage basins. During the third phase, which started in 1988, the

environmental degradation was intensified by the occupation of areas adjacent to the housin complex. This model of urbanization has caused irreversible damage to the hydrology and

water quality in the study area, and this article aims to provide an incentive for the creation of

land-use planning and management strategies that include protective and restorative measures

to reduce degradation of catchment basins as a result of urbanization

Published: December 2022

O presente artigo analisa a intensidade e a direção dos fluxos aéreos oriundos e destinados aos

principais aeroportos de Minas Gerais, contabilizando e mapeando a movimentação de passageiros,

cargas e aeronaves. Busca-se identificar as áreas de influência dos principais aeroportos, bem

como a importância econômica dos mesmos para o processo de desenvolvimento do Estado.

Emprega-se como suporte para a presente análise, o Modelo Alternativo de Geração de Viagens

Urbanas. Este modelo auxilia a compreensão das mudanças vivenciadas pelo setor aeroviário

mineiro, em especial aquelas processadas em Belo Horizonte, no que tange à demanda por

transporte aéreo de passageiros e cargas. No bojo destas transformações, são também apresentadas

e discutidas as principais causas e conseqÃ¼ências da recente transferência dos vôos comerciais

regulares do Aeroporto de Belo Horizonte (Pampulha) para o Aeroporto Internacional Tancredo

Neves (Confins). Os dados e as análises comparativas referentes aos fluxos aéreos dos aeroportos

mineiros, em relação às procedências e destinos, são processados e mapeados, com o intuito de

facilitar a identificação das áreas de influência dos aeroportos, bem como os impactos que estes

têm no desenvolvimento regional do Estado. Os resultados revelam que os aeroportos mineiros

guardam relação estreita com aqueles localizados nas cidades de São Paulo e Rio de Janeiro,

denotando a dependência que o setor aeroviário mineiro tem em relação Ã quelas praças.
O Livro didático nas séries iniciais: os "Diversos olhares" para uma coleção de geografia / TEXTBOOKS AND THE FIRST GRADES OF ELEMENTARY SCHOOL: several "points of viewâ€? for an edited textbook of Geography.
Authors: Santos Jakes Paulo Félix dos , Gomes Suely Aparecida
Published: December 2022

A idéia que nos instigou a pesquisar sobre o uso do livro didático de Geografia nas séries iniciais

do ensino fundamental, surgiu a partir de diversas discussões em sala de aula no Curso de Geografia

da Faculdade Católica de Uberlândia-MG. O assunto é polêmico e há divergências quanto à sua

importância e seu uso pelos professores. Assim, escolhemos uma coleção para análise, utilizada

em várias escolas da rede pública estadual em Uberlândia-MG. Procuramos identificar e analisar

a maneira como alguns conceitos geográficos, a nosso ver fundamentais para a compreensão do

espaço geográfico, são abordados nos livros didáticos. Ao buscar compreender a proposta

pedagógica de alguns livros didáticos de Geografia para as séries iniciais do Ensino Fundamental

faz-se necessário avaliar o referencial metodológico utilizado por seu autor - ou autores - e os

critérios que motivam sua escolha pelos professores e pelas escolas. Para dar efeito à análise,

comparamos o conteúdo programático sugerido pela Secretaria de Estado da Educação de Minas

Gerais com o conteúdo programático da coleção em foco. O objetivo desta análise não é, de modo

algum, desmerecer a obra, mas apontar caminhos e alguns critérios relevantes na escolha dos

livros didáticos para as séries iniciais do ensino fundamental. Este instrumento, a nosso ver, não

deve fomentar a discriminação, tampouco estampar imparcialidade ou neutralidade. Todavia,

deve oferecer elementos para que professores e alunos exerçam seu potencial e sua criatividade

sobre os temas propostos como uma ferramenta a mais a ser utilizada eficazmente em sala de aula.
ANÁLISE UNIDIMENSIONAL DOS PROCESSOS DE MISTURA NO SISTEMA ESTUARINO DO RIO PERIÁ (MA), BRASIL
Authors: Alcântara Enner Herenio de , Harari Joseph
Published: December 2022

O presente trabalho tem como objetivo analisar os processos de mistura no sistema

estuarino do Rio Periá (MA) e zonear o sistema através da classificação de Kjerfve

(1987). Foi utilizado o modelo matemático de Dyer e Taylor (1973), para analisar os

processos de mistura. Para obtenção dos objetivos, a batimetria do sistema estuarino

foi levantada, e com a mesma foram delimitados os limites atingidos pelas marés alta

e baixa. Foram analisados, num padrão unidimensional: as salinidades e as

concentrações e/ou frações de água doce nas marés alta e baixa; as taxas e os tempos

de descarga; e os volumes de água doce retidos no estuário nas estofas de enchente

e vazante. Foram obtidos os seguintes resultados: o volume de água no sistema possuí

um máximo de 64,96 * 106 m3e um mínimo 0,12 * 106 m3; o prisma de maré possui

máximo 7,1 * 106 m3 e mínimo de 0,045 * 106 m3; a concentração de água doce foi

maior na maré baixa (0,99 * 106 m3) do que na alta (0,91 * 106 m3); a concentração

de sal foi sempre maior na maré alta do que na baixa, sendo o valor máximo de 34

ups e o mínimo de 0,34 ups; quanto ao volume de água retido nas estofas de maré

baixa e alta, foi maior na estofa de vazante (5,36* 106 m3) do que na de enchente

(1,12 * 106 m3); finalmente, os tempos de descarga apresentaram maior valor na

maré alta (2 períodos de maré) e menor na maré baixa (1,24 períodos de maré). O

estudo permite concluir que a salinidade e a descarga de água doce no sistema

estuarino do Rio Periá são os fatores dominantes nos processos de mistura do mesmo.

Simple and Efficient Group Key Distribution Protocol using Matrices
Authors: Gupta Indivar , Pandey Atul , Singh Dhiraj Kumar
Published: December 2022

Group Key Distribution (GKD) protocols are designed to distribute a group key to several users for establishing a secure communication over a public network. The central trusted authority, called the key distribution center (KDC) is in charge of distributing the group keys. For securing the communication, all the users share a common secret key in advance with KDC. In this paper, we propose a secure and efficient Group Authenticated Key Distribution (GAKD) protocol based on the simple idea of encryption in matrix rings. In this protocol, each user registers in private with the KDC, while all the other information can be transferred publicly. The scheme also supports authentication of group keys without assuming computational hard problems such as Integer Factorization Problem (IFP).The analysis of our GAKD protocol shows that the proposed protocol is resistant to reply, passive and impersonation attacks. Our construction leads to a secure, cost and computation- effective GAKD protocol.
Novel Statistical Techniques for Conducting Accelerated Life Test to Demonstrate Product Reliability
Authors: Basha Mustaq , Ware Nliesh R
Published: December 2022

In Reliability Demonstration Testing (RDT), finding the right sample size is very important since the cost of the prototypes is high and difficult to make. If the sample size for the RDT is test is less, the amount of information obtained from the test will be insufficient, and the conclusion will be meaningless; on contrary, if the sample size is big/huge, the amount of information obtained from the test will be in excess of what is required, resulting in unnecessary costs. Most of the time, the required sample size and test time are decided based on the RDT test design. Resources required for RDT in terms of batch size and long testing-time is practically not feasible, due to limitation of the project schedule and budget. The reliability engineers must have a sound knowledge of type challenge/risk that is allowed for conducting RDT. The research paper with a case study provides the required information about the modern techniques adopted in reducing the sample-size and testing time with the help of accelerated test models such as Arrhenius, Erying etc., for conducting accelerated life test to demonstrate the product reliability.
Construction and Analysis of Petri Net Model for Distributed Cyber Physical Systems
Authors: Sood Vikas , Nema Malay Kumar , Kumar Rituraj , Nene Manisha J
Published: December 2022

A Distributed Cyber-Physical System (DCPS) composition poses challenges in determining its emergent behaviour. These challenges occur due to (1) the appearance of causal loops of information and energy flow through cyber and physical channels and (2) inherent non-determinism in the temporally ordered flow of events within independently evolving interacting processes of Constituent Systems (CSs). Hence, there is a need to construct a model of the envisaged schematic of DCPS composition for analysis and verification of its significant properties in the conceptual design stage of the system development life cycle.

This paper presents a procedure to construct DCPS composition models in Petri net formalism using distributed abstractions. The model for each CS is obtained from elementary constructs using compositional operators. The interaction among CSs occurs through channels obtained by connecting send and receive constructs of two CSs participating in an interaction. The internal processing within a CS characterizing its primary function is abstracted in a generic passthrough construct. Representing these constructs with compositional operators results in the complete DCPS model in Petri net formalism. A toolchain with Reference net workshop (Renew) as an integrated Petri net editing and analysis platform is configured to support DCPS modelling, simulation and analysis. The Renew tool functionality has been enhanced with a plugin designed and developed by authors to facilitate the drawing of the distributed composition model.

A low-level Petri net analysis (Lola) v2.0 plugin is employed to verify the Petri net and temporal properties of the modelled DCPS scenarios. The properties of the resultant model are verified using well-established algorithms to analyze Petri nets. Further, system properties specified using temporal logic can be verified using model-checking algorithms for Petri nets. A moderately complex scenario involving interactions among six CSs illustrates the presented approach.

Using augmented reality for collaborative multimodal storytelling
Authors: Asquith Steven , Frazier Erin
Published: December 2022

New technologies often influence the ways in which one shares linguistic
experiences. One such technology, Augmented Reality (AR), may initiate
concepts used in language learning through digital storytelling. This paper
describes an exploratory research project based on Choose Your Own Adventure
(CYOA) AR digital storytelling which investigated how Collaborative Learning
(CL) and AR can be used to enhance language learning. Different AR
activities were evaluated, culminating in an AR digital storytelling
project. Analyses of qualitative data collected after each activity provided
insights into important considerations when utilizing AR in the classroom.
The findings suggest that learners found considerable value in AR, but also
highlighted challenges in its application. CL was key to the success of this
project.

Authors: Carthy Úna
Published: December 2022

Within the parameters of the new Erasmus programme, this Blended
Intensive Programme (BIP) combines virtual exchange with physical mobility.
There were three institutions involved in this project: Letterkenny
Institute of Technology, Ireland, Hochschule Bremerhaven, Germany, and
Malaga Healthcare College, Spain. The virtual exchange ran for five weeks
from November to December 2021 and the physical mobility took place in
Bremerhaven in the first week of April 2022. Twenty-seven participating
students from diverse academic backgrounds engaged in shared tasks during
the virtual exchange on a Blackboard platform, hosted by Letterkenny
Institute of Technology and were awarded two ECTS credits, which was
embedded into their local curricula. Content was delivered using both
synchronous and asynchronous tools. The topic was global citizenship and
students collaborated in multicultural teams to create presentations on
their chosen topics. In addition to this team work, they also shared their
individual insights into the course content by posting to a discussion forum
in Weeks 1, 3, and 4.
Building the future by looking to the past: the evolution of research
strands in influential CALL papers
Authors: Choubsaz Yazdan , Jalilifar Alireza , Boulton Alex
Published: December 2022

To trace the evolution of research strands in published Computer
Assisted Language Learning (CALL) papers over time, a corpus of 426
highly-cited papers in four major CALL journals (ReCALL, CALL, LL&T, and
CALICO Journal) was compiled and coded using NVivo 12. All identified
aspects of technology-mediated language learning and teaching were collected
to produce a comprehensive list of 690 recurring research strands and then,
by adopting a constant comparison method, were merged to form 119 unique
research strands. The top 10 alone represent almost half of all research
strands: Computer-Mediated Communication (CMC), writing, vocabulary,
feedback, evaluation, learning environment, telecollaboration, design,
speaking, and grammar. This paper provides the rationale for the study along
with the methodology for data collection and analysis, with a particular
focus on the dominant and intermediary strands to inform future CALL
publications.

This study reports on the development of Parlure Games and explores its
pedagogical affordances. Parlure Games is a multi-dialectal listening and
decolonial conversation tool created to address the absence of variable
speech (including speech markers associated with native speaker status,
regional dialect, age, and race) found in the audiovisual material of adult
French learners in Montréal, Canada. Parlure Games enables instructors to
curate audiovisual content inclusive of different social and regional
dialects, and supports learners in understanding variable speech while
self-locating themselves in the process of learning a colonial

Remote online language teaching in a limited resource context during
COVID-19: the case of Egypt
Authors: El Ebyary Khaled , Shabara Ramy , Abdelaty Yara
Published: December 2022

This study aimed to investigate how the enforced online language
teaching operated in a limited resource context, i.e. Egypt. Based on the
Technology Acceptance Model (TAM), a nation-wide survey examined how 258
language teachers perceived the sudden move to remote online teaching and
whether such perceptions had an impact on their readiness and intention to
use this mode during and after the pandemic. Confirmatory factor analysis
was used and revealed that four factors constitute teachers’ perceptions.
Results showed that participants have positive perceptions of online
teaching, which consequently indicate that they were ready to use online
language teaching even after switching back to face-to-face. Demographic
data had no statistically significant effect on the participants’
perceptions of enforced online teaching. Teachers identified training needs
that show readiness and intention to engage more with this mode of
teaching.
L2 Chinese language teachers’ cross-cultural adaptation in teaching
online courses using videoconferencing tools in a foreign country during the
COVID-19 pandemic: a case study
Authors: Fan Yue , Cheng Li , Zhu Zhu
Published: December 2022

This case study is based on teachers’ personal observation of students
of Oberlin College, Ohio, US, and students’ feedback, and addresses
cross-cultural communication of Chinese as a foreign (L2) language teacher,
who is also the first author of this article. The study was conducted during
the global pandemic; L2 language teaching methods in Oberlin College had to
be shifted from face-to-face lectures to online teaching using
videoconferencing tools, particularly Zoom. It was used not only as the
online class platform, but also an additional live communication tool in
other activities. The case study presented in this article was conducted
mainly through observations in daily classes before and after the pandemic.
The results suggest that reserved personality and inadequate cultural
contact are factors of accultured difficulties for L2 Chinese language
teachers when working in the US. This paper proposes solutions for
preparations for a cross-cultural adaptability for Chinese language teachers
teaching L2 Chinese abroad, especially in conditions like using
videoconferencing tools in online teaching classes.
Chatbots in language learning: AI systems on the rise
Authors: Godwin-Jones Robert
Published: December 2022

The use of chatbots in language learning has been on the rise. In recent
Computer-Assisted Language Learning (CALL) research, there is a consensus
that rule-based, scripted voice systems are optimal for language learning.
Such systems integrate well into instructed language learning in that
interactions with the user are predictable and controlled. Open, AI-based
voice systems (such as in personal assistants like Siri) do not provide that
degree of task-oriented learning. However, the argument is made here that
they have the potential to provide open-ended conversational practice and
language development which aligns with an ecological, usage-based
perspective on language development.
Analyzing user interactions to estimate reading time in web-based L2
reader applications
Authors: Hollenstein Nora , Lungu Mircea F.
Published: December 2022

We propose to use reading time as a metric to report progress in
language learning applications. As a case study we use a web-based
application that enables learners of a foreign language to read texts from
the web and practice vocabulary with interactive exercises generated based
on their past readings. The application captures generic interactions with
the web page (e.g. switching to a different tab) but also interactions
directly related to language learning (e.g. clicking on a word to get a
translation). We propose two metrics for approximating reading times based
on user interactions with the web application. We analyze the correlation
between these metrics and other interaction metrics and show that active
time is the best metric for estimating the user’s actual involvement with
the texts and that it can be approximated from interaction metrics.
Systematic teaching of English affixes through the online material Affix
Master 10
Authors: Iso Tatsuo , Aizawa Kazumi , Katagiri Kazuhiko , Orita Mitsuru
Published: December 2022

This study examines whether ten weeks of direct instruction of affixes
with online systems can improve learners’ knowledge of affixes by using
Affix Master 10 (AM10), a collection of online self-study materials
developed by the current researchers. The aim of AM10 is to let students
comprehensively learn 30 prefixes and 31 suffixes. The two research
questions are (1) whether systematic instruction of affixes using the online
program improves learners’ knowledge of affixes (prefixes and suffixes), and
(2) whether systematic instruction of affixes using the online program
improves learners’ knowledge of affixes without direct instruction as well
as those with direct instruction. The results found that after learning with
AM10, the affix knowledge statistically significantly increased.
Furthermore, it seemed to contribute to the learning of the affix system
itself, which was evidenced by the gain in knowledge of untaught
affixes.
Using Google Voice Typing to automatically assess pronunciation

Published: December 2022

This study examined the use of a popular Automatic Speech Recognition
(ASR), Google Voice Typing (GVT), to automatically assess English as second
language pronunciation. It aimed to answer the following question: What is
the relationship between GVT-rated scores and human-rated scores? To answer
this question, we compared audio recordings of 56 oral placement tests,
rated by both human raters and GVT. Our results indicate that GVT scores
strongly correlated with human-rater scores, indicating that this
non-customizable ASR technology could be leveraged to increase the test
usefulness of language placement tests.
Students’ perceptions of digital storytelling in online EFL classes with
Zoom at a Japanese university
Authors: Kasami Naoko
Published: December 2022

This study reports on the results of students’ perceptions of Digital
Storytelling (DS) in online classes enhanced with synchronous Zoom meetings.
Two main problems were identified with remote English as a Foreign Language
(EFL) courses conducted primarily as asynchronous classes in spring 2020.
Firstly, seven of the 64 participating students (10.9%) found the DS
assignment very difficult. Secondly, there should be more opportunities for
students to learn from others. In order to solve these problems, the courses
in spring 2021 were enhanced with synchronous (90-minute) Zoom meetings held
approximately every two weeks to increase interaction and support in the
classes. The analysis of the post-questionnaires showed that there was a
slight improvement, with only five out of 77 students (6.5%) reporting that
they found the DS assignment very difficult; most students (92.2%) rated the
difficulty level of the assignment as appropriate. Regarding learning from
others, there were more positive responses from students in 2021.
Emotional and social engagement of teenager and young adult students of
EFL using MIM (Mobile Instant Messaging)
Authors: Martínez Dunia , Appel Christine
Published: December 2022

Mobile Instant Messaging (MIM) applications have come into focus as
potential tools to improve English language instruction, and teachers can
engage more students from different backgrounds in English as a Foreign
Language (EFL) classes thanks to MIM apps’ distinctive features, like
WhatsApp. Most of the reported studies on the use of WhatsApp in the
teaching of foreign languages were performed in university or adult learning
environments. The present study explores how social and emotional engagement
manifest themselves in a popular instant messaging application group
(WhatsApp) used by teenagers learning EFL. A focus group, a Likert scale
survey, and a transcript of the WhatsApp chat were the three main sources
from which data was gathered. Members’ interaction records were retrieved
and inductive thematic analysis was used to examine them. These findings
suggest that WhatsApp provided communicative opportunities to all students,
including those who did not fully engage. However, further research with a
larger number of students in different contexts is necessary.
Telecollaboration and languages for specific purposes

Published: December 2022

There is no doubt that telecollaboration currently plays an important
role in foreign language learning and, not less so, in the field of English
for Specific Purposes (ESP). Guth (2020) highlighted how telecollaboration
has rapidly evolved in the past years as an innovative approach, and how it
has brought together a whole community of academics and researchers
interested in the field. In this paper, a brief overview of the various
presentations that took place in the EuroCALL Computer-Mediated
Communication (CMC) Special Interest Group (SIG) Symposium is offered. The
paper introduces four projects based on telecollaboration contextualised
within an ESP classroom in higher education. The first one focuses on a
collaborative debate project using English as a lingua franca; the second
elaborates on improving learners’ pragmatic skills through telecollaborative
role-plays; the third describes an immersive Virtual Exchange (VE) aiming to
foster the students’ civic and entrepreneurial competence, while enhancing
their intercultural communicative competence. The fourth project aimed at
improving students’ business communication and management skills in English
in a multicultural environment.
Twitter as a dynamic language learning platform for learners of Irish as
an additional language in a primary school setting in Ireland: review and
recommendations
Authors: O’Toole Jane , Devitt Ann
Published: December 2022

This paper explores the utilisation of Twitter as a dynamic language
learning platform in order to create an authentic domain of use for learners
of Irish as an Additional Language (IAL) in a primary school setting in
Ireland wherein 20 fourth class children and their parents participated. The
Irish language context is firstly introduced, which contextualises a
rationale for utilising Twitter for language learning. Teacher, child, and
parent engagement with Twitter is then outlined with reference to the action
research methodology employed. The repository of class tweets, periodic
participant advisory group discussions and questionnaires, coupled with
teacher-researcher reflection informed a qualitative data analysis. Results
indicate notable student engagement with and enjoyment of tweeting in class
as Gaeilge [in Irish] whereby the class Twitter account emerged as a
practicable language learning platform. Its affordances enabled the student
composition and publishing of short texts (tweets) and the provision of
authentic Irish tweets for class reading. Parent and child engagement out of
class, while relatively low, also demonstrated a promising additional domain
of use, subject to the negotiation of orientation-related and
implementation-related challenges for learners in a blended setting. In
conclusion, recommendations to support the use of Twitter in endangered
language school contexts are suggested.
Exploring the impact of a group dynamics training activity on learner
engagement during online classes of French as a foreign language
Authors: Rosso Ana , Robbins Jackie , Appel Christine
Published: December 2022

This paper focuses on the impact of introducing a Group Dynamics
Training Activity (GDTA) on learners’ reported engagement during the course.
The context is a university Common European Framework of Reference for
languages (CEFR) B2 French language online course over the course of two
semesters. Data was collected in the form of online surveys during the
semester prior to the introduction of the GDTA and during the semester when
it was administered. This case study uses quantitative analysis of
Likert-scale question responses and qualitative analysis of open fields in
the questionnaires using a content analysis methodology. Results indicate
that the GDTA had a positive impact on learners, particularly on the social
and cognitive dimension of learner engagement.
Differences in the effectiveness of remote online teaching and
face-to-face on-campus teaching using the DDL approach in L2 English
verb-noun collocations
Authors: Satake Yoshiho
Published: December 2022

This study explores the effectiveness of Data-Driven Learning (DDL)
approach to second-language (L2) English vocabulary learning in on-demand
online distance learning at a private university in Tokyo, Japan. The
participants were 49 Japanese undergraduates, intermediate L2 English
learners at the B1 level in the Common European Framework of Reference for
languages (CEFR). The experimental group consisted of 25 students who
completed verb-noun collocation correction tasks between the pre-test, and
the post- and delayed post-tests. The control group consisted of 24 students
who took the tests but did not perform the error correction task. The
results show that for memorizing verb-noun collocations, on-demand online
DDL – in which learners refer to screenshots of concordance lines – is as
effective as DDL in a traditional on-campus setting, where learners search
the Corpus of Contemporary American English (COCA) for themselves, even
though the learning activities in remote online on-demand and face-to-face
on-campus DDL are not exactly the same. This study suggests the potential of
DDL in online on-demand classes. When a variety of teaching methods are
being explored, DDL seems a viable option as an approach to L2
teaching.
ESPACE L2: exploring spacing effects in explicit and implicit online
learning of L2 English
Authors: Whyte Shona , Edmonds Amanda , Palasis Katerina , Gerbier Emilie
Published: December 2022

Language researchers and teachers have long been interested in the
timing of learning, and the distributed practice effect, whereby greater
inter-session intervals result in longer retention, is well-known (Kim &
Webb, 2022). Many L2 studies have focused on the intentional learning of
lexis (Edmonds, Gerbier, Palasis, & Whyte, 2021), neglecting implicit
learning and syntactic development (Rogers, 2021). The present project
includes both explicit vocabulary learning activities and incidental
exposure to a complex syntactic structure via a bespoke online L2 English
learning platform. The goal is to investigate the two types of learning in
two spacing conditions. This paper describes (1) the learning activities
created to present opportunities for explicit vocabulary learning and the
concealed syntactic input, and (2) the tests used to evaluate participants’
receptive and productive knowledge of target items. It aims to inform
computer assisted language learning design with respect to pedagogical
progression, learning activities, feedback, and learning schedules.

The local governance of COVID-19: Insight from Lesotho’s response and mitigation
Authors: Leboto-Khetsi Lucia , Kohima Jennilee , Rwanqa-Mokete Fefisa , Nel Verna
Published: December 2022

Pandemics are deemed accidents of history. Their control and impacts span over economic, social, geopolitical and ideological considerations. This paper attempts to answer how Lesotho responded to the COVID-19 pandemic, which factors hindered local-level implementation of COVID-19 response and mitigation, and how the kingdom’s local government disaster preparedness can be improved. A desktop study supported by virtual consultations with relevant players was conducted to gain insight for this study. Content and thematic analysis established a lack of administrative and financial decentralization in Lesotho, which had detrimental implications for COVID-19 response and mitigation.
Context matters: toward a multilevel perspective on context in clinical reasoning and error
Authors: Choi Justin J. , Durning Steven J.
Published: December 2022

Context in diagnosis and management of patients is a vexing phenomenon in medicine and health professions education that can lead to unwanted variation in clinical reasoning performance and even errors that cause patient harm. Studies have examined individual-, team-, and system-level contextual factors, but the ways in which multiple contextual factors can interact, how both distracting and enabling factors can impact performance and error, and the boundaries between context and content information are not well understood. In this paper, we use a theory-based approach to enhance our understanding of context. We introduce a multilevel perspective on context that extends prior models of clinical reasoning and propose a micro-meso-macro framework to provide a more integrated understanding of how clinical reasoning is both influenced by and emerges from multiple contextual factors. The multilevel approach can also be used to study other social phenomena in medicine such as professionalism, learning, burnout, and implicit bias. We call for a new paradigm in clinical reasoning research and education that uses multilevel theory and analysis to enhance clinical reasoning performance expertise and improve the quality of patient care.
Monitoring the boundary of an adhesive coating to a steel substrate with an ultrasonic Rayleigh wave
Authors: Ulbrich Dariusz
Published: December 2022

Coating–substrate adhesive joints are used in mechanical engineering and automotive vehicle construction. Monitoring their condition, both at the manufacturing and operational stages, is important for durability and extended lifetime. The article proposes a method for continuous monitoring of the state of the coating–substrate joint using ultrasonic surface wave. The waveforms of ultrasonic parameters such as gain of pulse of ultrasonic wave, resonant frequency and bandwidth over the lifetime of the tested joint were determined. The resonant frequency change precedes the final stage of degradation of the coating–substrate connection, which leads to complete detachment of the coating from the body sheet. Both, during the period of constitution and degradation, rapid changes in the pulse gain of the ultrasonic surface wave were recorded. The knowledge about the waveforms of the selected ultrasonic wave parameters makes it possible to assess the condition of the joint and is the basis for deciding on its further operation or repair.

Published: December 2022

The substitutions of the chlorine atoms in p-dichlorobenzene (DCB) or the chlorine end-groups of polyphenylene sulfide (PPS) by sodium N-methyl-4-aminobutyrate (SMAB) are important reactions in the polymerization of PPS. The reaction process of DCB with SMAB was studied under conditions similar to the polymerization of PPS. The molecular structures of the products were analyzed through high-performance liquid chromatography, liquid chromatography-mass spectroscopy, gas chromatography-mass spectrometry, and other methods. Several pairs of para- and meta-isomer products were found, which indicates the coexistence of both nucleophilic addition–elimination (SN2Ar) mechanism and aryne intermediate mechanism. Based on mechanism analysis, the networks of reactions of DCB with SMAB were proposed and the effects of the ratio of SMAB to DCB, water content, and temperature on the reaction process were studied.
Online language education courses: a Chinese case from an ecological perspective
Authors: Mei Fang , Lu Yunru , Ma Qing
Published: December 2022

In this study, we examined the usefulness of and students’ perceptions of a one-to-one online oral EFL course. Based on van Lier’s learning theory of ecology, we studied the positive aspects that encouraged learning and the negative aspects that required improvement. A total of 18 young-adult English learners from different parts of China were invited to attend three one-to-one (teacher–learner) online lessons designed by the researchers. A quasi-experimental one-group design was used to examine the effectiveness of the online course. In addition, an online survey and semi-structured individual interviews were conducted to reveal the learners’ views and perspectives on the course. The results indicated that the participants made good progress in terms of complexity in oral skills and perceived the course to be highly useful, especially regarding opportunities to express personal views, timely scaffolding, and efficient feedback from the teacher. Based on the findings, a number of implications for improving the course are provided, in addition to suggestions for a better one-to-one online oral English course model.

Published: December 2022

Objective

To prove that calcium alginate beads can be used as scaffolds during in vitro culture.

Methods

Mouse preosteoblastic cells (MC3T3-E1) were encapsulated in calcium alginate hydrogel beads. The Cell Counting Kit-8 (CCK-8) assay was used to assess cell viability at 2, 5, 8, 11, 14, and 21 days. Calcein-AM and propidium iodide (PI) were employed for live/dead staining.

Results

MC3T3-E1 cells were alive on day 21 and had the highest viability on day 14.

Conclusion

MC3T3-E1 cells could be encapsulated in calcium alginate hydrogel beads and cultured. Calcium alginate hydrogel beads can be used as scaffolds for three-dimensional in vitro culture.
Soziale Systeme? Systemtheorie digitaler Organisation
Authors: Manhart Sebastian , Wendt Thomas
Published: December 2022

Digitalisierung erscheint als Fortsetzung der Organisation mit anderen Mitteln: Digitalisierung vollzieht sich vor allem in und durch Organisationen, was diese in ihrer Struktur nachhaltig verändert. Dies wirft die Frage nach der Form und Funktion von Organisationen in der digitalen Gesellschaft auf und erfordert eine Neufassung der Theorie der Organisation. Für die Digitalisierung wie für Organisationen ist die operative Differenzierung zwischen Information und Kommunikation zentral. Die paradoxe Evidenz einer ausbleibenden Wahrnehmung dieser Sinndifferenz wird genutzt, um ein präzisiertes systemtheoretisches Verständnis von Digitalisierung und Organisation vorzuschlagen. Ein Vergleich wahrnehmungsneutraler Informationsverarbeitung mit der wahrnehmungskultivierenden Kunst verortet die semiotische Differenzierung des Sinnbegriffs systematisch in der Systemtheorie. An Beispielen aus der Geschichte des Managements und des organisierten Messens wird der Ausdifferenzierungsprozess in seiner empirischen Triftigkeit vorgeführt. Der Artikel schließt mit einem Ausblick auf die Konsequenzen der subtilen Organisation der Digitalisierung für die Gesellschaft.
Verantwortungsvolle Maschinen ohne Verantwortlichkeit? Datenintensive Algorithmen in Organisationen

Published: December 2022

Die Frage der Verschiebung von Verantwortung, die durch den vermehrten Einsatz von datenintensiven Algorithmen verursacht wird, beschäftigt seit einigen Jahren die sozialwissenschaftliche Forschung. Dabei geht es vor allem darum, welche Personen oder Instanzen dafür verantwortlich sein sollen, wenn sich Entscheidungen als diskriminierend, sachlich falsch oder ungerecht herausstellen. Aus soziologischer Perspektive fällt auf, dass in diesen Debatten nicht trennscharf zwischen Verantwortung und Verantwortlichkeit unterschieden wird. In unserem Beitrag greifen wir diese Unterscheidung so wie sie von Niklas Luhmann formuliert wurde auf, um Veränderungen und Kontinuitäten des Organisierens zu analysieren, die mit dem Einsatz datenintensiver Algorithmen verbunden sind. Wir zeigen, dass Algorithmen in organisationalen Entscheidungsprozessen Unsicherheit absorbieren und somit durchaus Verantwortung übernehmen, aber nicht für Fehler verantwortlich gemacht werden können. Durch den Einsatz von Algorithmen wird Verantwortung in Assemblagen von Personen und Technik zerlegt, während die Zuschreibung von Verantwortlichkeit hochgradig kontrovers wird. Daraus entstehen neue Diskrepanzen zwischen Verantwortung und Verantwortlichkeit, die insbesondere für das organisationsinterne Vertrauen und die Innovationsfähigkeit von Organisationen folgenreich sein können.
The Analyst's Self-Care: Further Reflections after the Pandemic on Cultivating Resilience and the Essential Role of the Body-Mind Relationship in Clinical Practice
Authors: Zerbe Kathryn J.
Published: December 2022

Sparse attention is paid in the psychoanalytic literature to the management of self-care needs of the analyst. I suggest that pandemic fatigue experienced by psychotherapists during the Covid-19 global crisis has thrown into bold relief the requirement for clinicians to attune to the body, particularly the requirement for rest and creative space. Physical and emotional exhaustion is multidetermined and not unique to this time period; the global crisis appears to have unmasked particular difficulties in sensing and tending to requirements of the body-mind. Changes observed in sleep, dreams, exercise, eating, and somatic states during the pandemic raise additional questions about modifiable risk factors of burnout. Drawing upon contemporary evidence emerging from the fields of cognitive psychology, neuroscience, and psychodynamic practice and theory, suggestions are made to assist the analyst in rendering essential self-care.
