Authors: Chaves Marcirio Silveira , Araújo Cíntia Cristina Silva de , Teixeira Laura Ribeiro , Rosa Debora Virginio , Júnior Irapuan Glória , Nogueira Cláudia Dias
Published: March 2022

In any organization, dealing with lessons learned is a complex issue that involves people, processes and technologies. Although lessons learned processes are already well established in the project management community, the use of modern web technologies to support them is still in its infancy. This paper introduces a new model to manage lessons learned in PMBoK process groups. This model draws upon interdisciplinary literature, which embeds lessons learned processes, shared context and Web 2.0 service models. The model is supported by Web 2.0 technologies and centered in PMBoK process groups to allow a thorough overview of the project. An exploratory focus group was set up to validate the model qualitatively within a constructivist ontology and an interpretive epistemology. The adoption of this model can help academics and practitioners using PMBoK process groups to acquire a better understanding of managing lessons learned in projects.
Adoption of web-based group decision support systems: experiences from the field and future developments
Authors: Hillegersberg Jos van
Published: March 2022

While organizations have massively adopted enterprise information systems to support business processes, business meetings in which key decisions are made about products, services and processes, are usually held without much support of information systems. This is remarkable as group decision support systems (GDSS) seems to fit for this purpose. They have existed for decades and modern versions benefit of web-based technologies, enabling low cost anyplace, any time and device independent meeting support. In this exploratory case research, we study nine organizations in four different adoption categories to learn more about the reasons for the relatively slow adoption of web-based GDSS. Using the Fit-Viability adoption framework we conduct interviews with organizations that have experience with using GDSS. We conclude that adopting GDSS requires considerable and carefully planned change of processes that are deeply grounded in the organization. Existing meeting routines need to be adapted. Introduction needs to be carefully planned and room for face-to-face meetings and creativity sessions away from the keyboard need to be built in depending on the type of meeting. Not all companies find the cost level affordable. Clear and convincing business cases are lacking. Still the added value is ranked highly and there are frequent and enthusiastic user organizations that may lead the way for others. Their success stories show others how to mitigate problems.
Managing project interdependencies in IT/IS project portfolios: a review of managerial issues
Authors: Bathallath Sameer , Smedberg Åsa , Kjellin Harald
Published: March 2022

Adequately managing project interdependencies among diverse and simultaneous projects is deemed critical for successful implementation of project portfolios. The challenge is significant because it may entail managing a complex network of project interdependencies that keeps changing over time. The present study investigates the managerial challenges that may undermine effective management of project interdependencies in IT/IS project portfolios. The investigation is based on evidence from reviewing relevant literature and documented studies associated with managing project interdependencies. The main contribution of this study is to discuss three managerial challenges of project interdependencies in project portfolios. We discuss the challenges from three perspectives: types of interdependencies; patterns of interaction in interdependencies; and cost/benefit impact of project interdependencies.
Improving intercultural competency in global IT projects through recognition of culture-based behaviors
Authors: Amster Richard , Böhm Christina
Published: March 2022

The success of global IT projects is highly influenced by culture-based behaviors. Issues between individuals arise when behaviors are (mis-)perceived, (mis-)interpreted, and (mis-)judged by using the perceiver’s expectations, beliefs, and values. Misperception results when the behavior is not anticipated because it would not occur in ones own culture. As a result, behavior should be the starting point for cross-cultural research. But, studies have primarily focused on belief and value systems which are more abstract and less specific than behaviors. This paper presents a study that analyzed cultural behavioral differences between Indian project managers and their counterparts in other countries. The conducted qualitative, semi-structured interviews revealed insights into cross-cultural challenges and shed light on the complex ways that culture-based behaviors impact IT projects. The study identified 127 behaviors that significantly affected project success and cross-cultural cooperation between Indian managers and managers from all over the world. These behaviors were grouped into 19 behavior clusters. Understanding these behavior clusters, and correlating these behaviors to values and beliefs, will improve project collaboration, and inform cross-cultural training strategies. In addition, existing cultural dimensions were reduced in scope, additional dimensions were defined for clarity, and new business-related dimensions were identified. Finally, based on the study’s results, the paper suggests four important components that should be added to cross-cultural training programs for international project managers.
Challenges of adopting agile methods in a public organization
Authors: Nuottila Jouko , Aaltonen Kirsi , Kujala Jaakko
Published: March 2022

Agile development methods are widely used among business enterprises. Since the introduction of the Agile Manifesto in 2001, several agile methods have been implemented, first in single-team set-ups and later in larger multi-team set-ups for complex Information Technology (IT) system development. However, the adoption of agile methods has been slow in the public sector. This is also reflected in the academic literature, as there are only a few studies discussing agile adoption in public organizations. This paper contributes to research on the use of agile practices specifically in the context of public organizations, and sheds light on the challenges a public organization may face while adopting these practices. The aim of this paper is to identify and categorize the challenges that may hinder efficient adoption and use of agile methods in public IT projects that include private software vendors. This research is based on a case study of a large governmental office. As a result, this paper presents several categories of identified challenges, the root causes of these challenges, and a discussion of the characteristics of these challenges for the public sector.
Change management lessons learned for Lean IT implementations
Authors: Kobus Jörn , Westner Markus , Strahringer Susanne
Published: March 2022

Lean Management is a standard production mode that has been familiar to production organizations for several decades. To date, however, academic literature has presented surprisingly little information about the application of Lean Management in Information Technology (IT) organizations, or what is called Lean IT. Drawing upon an empirical qualitative case study of the IT departments of two multinational companies, in this paper we identify change management lessons learned for Lean IT implementations, as well as seven characteristics of a corresponding change management approach. As an extension of our work, researchers should validate and expand our initial findings, preferably in a quantitative setting.
Virtual teamwork in the context of technological and cultural transformation
Authors: Großer Birgit , Baumöl Ulrike
Published: March 2022

Megatrends affect all individuals and organizations in our society. Mobility and flexibility are examples of megatrends that influence our everyday lives and also intensely alter the ways we work. The deployment of virtual teams meets the new chances emerging with these trends. Employees aspire to work virtually due to benefits, such as flexibility regarding the locations and hours for working. Organizations deploy virtual teams to remain competitive regarding new technological opportunities, employee retention and cost efficiency in an increasingly digital environment. Organizations can guide their change towards virtuality by building on the knowledge of practice as well as scientific insights regarding the deployment of virtual teams. In order to provide a holistic view on the structures and processes affected by such a change and thus provide guidance, a framework for analyzing and planning organizational change is adapted to virtual teamwork and presented in this paper. The framework shows that the deployment of virtual teams affects the whole organization. This comprehensive view on the implementation of virtual teamwork allows an integration of virtual teams and focusses on their performance. The adapted framework furthermore provides links for further in-depth research in this field.
Reducing and Calibrating for Input Model Bias in Computer Simulation
Authors: Morgan Lucy E. , Rhodes-Leader Luke , Barton Russell R.
Published: March 2022

Input model bias is the bias found in the output performance measures of a simulation model caused by estimating the input distributions/processes used to drive it. When the simulation response is a nonlinear function of its inputs, as is usually the case when simulating complex systems, input modelling bias is amongst the errors that arise. In this paper, we introduce a method that recalibrates the input parameters of parametric input models to reduce the bias in the simulation output. The proposed method is based on sequential quadratic programming with a closed form analytical solution at each step. An algorithm with guidance on how to practically implement the method is presented. The method is shown to be successful in reducing input modelling bias and the total mean squared error caused by input modelling error.

Summary of Contribution: This paper furthers the understanding and treatment of input modelling error in computer simulation. We provide a novel method for reducing input model bias by recalibrating the input parameters used to drive a simulation model. A sequential quadratic programming approach with an explicit solution is provided to recalibrate the input parameters. The method is therefore computationally inexpensive. An algorithm outlining our proposed procedure is provided within the paper. An evaluation of the method shows the method successfully reduces input model bias and may also reduce the mean squared error caused by input modelling in the output of a simulation model.
Dynamic Vehicle Allocation Policies for Shared Autonomous Electric Fleets
Authors: Dong Yuxuan , De Koster René , Roy Debjit , Yu Yugang
Published: March 2022

In the future, vehicle sharing platforms for passenger transport will be unmanned, autonomous, and electric. These platforms must decide which vehicle should pick up which type of customer based on the vehicle’s battery level and customer’s travel distance. We design dynamic vehicle allocation policies for matching appropriate vehicles to customers using a Markov decision process model. To obtain the model parameters, we first model the system as a semi-open queuing network (SOQN) with multiple synchronization stations. At these stations, customers with varied battery demands are matched with semi-shared vehicles that hold sufficient remaining battery levels. If a vehicle’s battery level drops below a threshold, it is routed probabilistically to a nearby charging station for charging. We solve the analytical model of the SOQN and obtain approximate system performance measures, which are validated using simulation. With inputs from the SOQN model, the Markov decision process minimizes both customer waiting cost and lost demand and finds a good heuristic vehicle allocation policy. The experiments show that the heuristic policy is near optimal in small-scale networks and outperforms benchmark policies in large-scale realistic scenarios. An interesting finding is that reserving idle vehicles to wait for future short-distance customer arrivals can be beneficial even when long-distance customers are waiting.
Association of Perfectionism with Job Search Behavior and Career Distress among Nursing Students in South Korea
Authors: Si Eun A , Lee Gyung Joo
Published: March 2022

Purpose: Understanding the influence of perfectionism among senior nursing students is imperative for addressing strategies to reduce career distress and enhance job search behavior. The purpose of this study was to identify perfectionism types among senior nursing students in South Korea. Differences in career distress and enhanced job search behavior for each perfectionism type were compared.Methods: A cross-sectional, descriptive design was employed. A total of 211 nursing students completed surveys for Perfectionism, Job Search Behavior, and Career Distress. Cluster analysis and post-hoc tests were conducted.Results: A total of 80.1% were classified into the perfectionism group, including adaptive (49.8%) and maladaptive (30.3%). Maladaptive groups showed the highest discrepancy between standards and their perceived achievements as well as career distress. Job search behavior was the highest in the adaptive perfectionism group but the lowest in the non-perfectionism group.Conclusion: Nursing educators should consider career coaching customized by each perfectionism type to improve job search behavior among nursing students.

Authors: Lee Jihyun , Choi Heeseung
Published: March 2022

Purpose: This study aimed to systematically evaluate the content and effect of using Korean mobile apps for mental health care as reported in previous studies.Methods: We conducted a systematic review according to PRISMA guidelines. Randomized controlled trials published up to May 2021 were searched in the PubMed, Cochrane Library, EMBASE, CINAHL, PsycINFO, RISS, KISS, and KoreaMed databases. We used the Cochrane risk-of-bias tool version 2 for randomized trials to evaluate the selected studies.Results: Out of 3,374 articles retrieved, 12 were selected. These studies included people with mental disorders (mood disorder, panic disorder, or obsessive-compulsive disorder), psychiatric symptoms (depression, anxiety, attention deficit, etc.), and people in specific groups (college students or nurses). The apps were based on cognitive-behavioral therapy, cognitive training, well-being cognition technique, or relaxation techniques. The apps were effective in reducing depression, anxiety, panic attacks, attention deficit, negative emotions, and dysfunctional attitudes, and boosting memory and positive emotions.Conclusion: Mobile apps with well-established, theory-based content can serve as an effective intervention for managing several mental health symptoms. However, the scope of the research subjects and symptoms in Korea remains limited. Further studies with more varied populations and symptoms are required.
EDUCAÇÃO DO CAMPO: ALGUNS APONTAMENTOS SOBRE A PRÁTICA PEDAGÓGICA E FORMAÇÃO CONTINUADA NO MUNICÍPIO DE REBOUÇAS-PR
Authors: Vereta Crislaine Leticia , Machado Polon Sandra Aparecida
Published: March 2022

A pesquisa teve como objetivo, analisar e denominar como se encontra o desenvolvimento da formação continuada dos professores que atuam em escolas do campo, geograficamente limitado no município de Rebouças-Pr. Por este viés, buscamos reconhecer como está o “olhar” pedagógico em relação aos professores que atuam nas escolas campesinas; bem como o propenso desenvolvimento quanto à formação continuada para estes professores regentes. A pesquisa qualitativa do tipo exploratória foi desenvolvida a partir de estudo bibliográfico e trabalho de campo. Assim, a metodologia optou, para a coleta de dados, um questionário com perguntas abertas e fechadas. A enquete foi direcionada aos professores, das duas escolas localizadas nas áreas rurais. Em seguida, realizou-se uma entrevista com as coordenadoras dessas escolas e com a Secretaria de Educação do município de Rebouças. Neste recorte, buscou-se a sondagem ofertada, quanto à formação continuada dos educadores e também, inclusos alguns relatos de como se encontra a prática pedagógica voltada à educação do campo na atual conjuntura no município sinalizado. Ao friccionar determinados traços dessa trajetória, os resultados obtidos permitem apontar a existência de certos “ruídos” por parte dos professores envolvidos na pesquisa. O que apontou dúvidas principalmente nos  iniciantes nesta área e logo, inexperientes na arte de ensinar.  Embora tenham declarado não conhecer sobre a temática Educação do Campo, por outro lado, houve contradição quando assinalaram nos termos que a proposta já foi salientada em formações continuadas. Nesta linha a presente pesquisa almeja abrir espaço para constantes pesquisas relacionadas ao tema em destaque.
A ATUAÇÃO DO MOVIMENTO ESCOLA SEM PARTIDO EM QUATRO ESCOLAS MUNICIPAIS DE CAMPINAS-SP
Authors: Caballero Alan Isaac Mendes , Dias Junior Antonio Carlos
Published: March 2022

Na década de 2010, o discurso “ideologia de gênero” promoveu uma situação mundial de pânico moral, representado no Brasil pelas cruzadas antigênero do Movimento Escola Sem Partido. Nosso objetivo é discutir a materialidade desse currículo de gênero em escolas municipais de Campinas-SP a partir dos resultados encontrados em nossa dissertação de mestrado. A pesquisa parte da abordagem do ciclo de políticas, com especial ênfase para o contexto da prática, aliada a um referencial teórico feminista pós-estruturalista, permitindo articular a categoria gênero com o conceito de atuação sobre uma sexopolítica que age na intenção de reagrupar o dispositivo de sexualidade ao dispositivo pedagógico. Foram realizadas entrevistas semiestruturadas com oito gestoras/es de quatro escolas participantes. Nossos resultados evidenciam que as situações de pânico moral performadas, sobretudo, por mães e evangélicas/os, têm sido pouco efetivas nas escolas pesquisadas em decorrência das técnicas de acolhimento encontradas na atuação da gestão, assegurando a separação entre dispositivo pedagógico e dispositivo de sexualidade. Também reconhecemos que a cultura docente do município em torno de uma educação inclusiva de gênero encoraja a produção desses currículos de gênero. No entanto, as escolas e suas/seus atrizes/atores continuam sujeitos a limitações sobre sua autonomia curricular e são impactados subjetivamente pelas cruzadas antigênero, o que exige persistência e continuidade em suas atuações para resistir à governamentalização de seus currículos.
CIBERFEMINISMO E EDUCAÇÃO: DISCURSOS, RACIALIDADE E QUESTÕES DE GÊNERO
Authors: Borges Luzineide Miranda , Pinho Ananda Radharanni Brasil
Published: March 2022

No contexto de isolamento e distanciamento social, por conta da pandemia do COVID19, as redes sociais digitais se configuram como grande aliada comunicativa. O digital em rede tem potencializado o compartilhamento de informações em tempo real, fortalecendo a comunidade científica na divulgação e produção do conhecimento. O objetivo desse artigo é refletir como as mulheres negras brasileiras apropriam-se das redes sociais digitais para construir uma identidade de gênero, de raça e classe positiva, contribuindo para resistência e emancipação do grupo. Para compreender as militâncias das mulheres negras, fez-se necessário analisar os processos de identidades que essas mulheres deixam nas suas redes sociais digitais. Para compreendermos as categorias de analises: raça, gênero e classe dialogamos com as pesquisadoras: Sueli Carneiro, Angela Davis, Bell Hooks, Deepika Bahri, Djamila Ribeiro, Lélia Gonzáles e Thaysa Malaquias. A metodologia utilizada foi a netnografia (HINE,2015) e a análise dos dados teve como base os estudos sobre cotidianos educativos e narrativas digitais (SANTOS, 2014). O campo de pesquisa foram as Challenges produzidas pelas mulheres negras e compartilhadas em suas redes sociais digitais no início da pandemia, a aqui no Brasil. Negritar as potências e desafios das lutas e narrativas das mulheres é crucial, pois amplia e fortalece as construções de mulheres negras como protagonistas de sua história. A relação estabelecida entre o feminismo negro e a tecnologia permite que se crie um novo campo de descoberta e consequentemente de análise.

Published: March 2022

Apresenta uma pesquisa qualitativa sobre as produções científicas disponíveis no Google Acadêmico e que versam sobre Práticas Pedagógicas Inovadoras e o uso de Tecnologias Digitais Imersivas no contexto educativo. O objetivo geral foi elencar as experiências docentes e os projetos educacionais pautados nas Tecnologias Digitais e Imersivas no contexto nacional. A fundamentação teórica percorreu a teoria de Pereira (2005); Miranda (2007); Vieira (2011); Alves (2020); Carneiro (2020), dentre outros. O método de produção de dados foi a Revisão Sistemática na plataforma Google Acadêmico pelo uso dos termos de busca: “educação infantil” AND “tecnologias imersivas”. O corpus de análise se constituiu a partir de critérios de inclusão e exclusão e a construção dos resultados ocorreu pela Análise Interpretativa dos títulos, resumos e palavras-chave dos documentos, seguido pela leitura dinâmica para identificação dos aspectos considerados relevantes. Foram utilizadas quatro questões norteadoras para a interpretação dos resultados, sendo elas: a) A que público se destinou? b) Que disciplina ou conteúdo orientou a Prática de Pedagógica? c) Houve utilização de Tecnologia Digital ou Imersiva? d) Havia relação com Projeto de Ensino ou de Pesquisa? Os resultados obtidos demonstraram uma baixa representatividade de estudos sobre a temática da pesquisa disponível no Google Acadêmico, motivando a reflexão sobre os percalços que dificultam o encontro de professores da educação básica com documentos científicos que socializam experiencias sobre uso de Tecnologias Digitais e Imersivas como Prática Pedagógica Inovadora.
Docência na creche: contradições e enfrentamentos
Authors: Nascimento Ana Paula Santiago do , Rodrigues Claudia Meire , Silva Dilma Antunes
Published: March 2022

Este artigo tem como foco a discussão sobre como as pesquisas da área de educação vêm tratando as funções docentes nas creches do país. Resulta de um levantamento de trabalhos (teses, dissertações e artigos publicados em revistas e em anais de congresso) produzidos entre os anos de 2015 e 2021, que objetivou identificar questões referentes à identidade, formação docente (inicial e continuada) e à relação entre educação e cuidado, entendendo que essas três categorias podem revelar como a área vem trabalhando com a existência de diferentes profissionais, com e sem formação específica, responsáveis por garantir o direito à educação de bebês e crianças pequenas em  instituições educacionais. Adotou-se as três etapas iniciais do Estado do Conhecimento (MOROSINI, KOHLS-SANTOS, BITTENCOURT, 2021), como metodologia e, em complementaridade, recorreu-se a um levantamento de dados educacionais no Censo Escolar 2020 para apresentar um perfil dessas profissionais. Como resultado, identifica-se que a temática aqui abordada não é focalizada na maioria dos estudos. Embora haja significativo número de trabalhos que indiquem a coexistência de profissionais sob diferentes cargos atuando na educação infantil, estes não problematizam aspectos como: possível hierarquização do trabalho pedagógico, divisão de tarefas, consequências para as crianças; clima escolar; valorização das autoimagens profissionais etc. São poucos os trabalhos que tratam explicitamente da coexistência, no mesmo ambiente, de docentes e outras profissionais “não docentes”, evidenciando assim, a necessidade de mais estudos nesse campo, a fim de ampliar a visibilidade e reconhecimento do trabalho desenvolvido junto a crianças bem pequenas, em creches.

Published: March 2022

A partir das inquietações de docente em turma de Educação Infantil sobre as multifaces do processo de avaliação com ênfase na documentação pedagógica, e tendo como dimensão as peculiaridades e as atribuições legais docentes da primeira etapa da Educação Básica (DCNEI-2009 / LDBEN 9.394/96); busca-se neste artigo evidenciar como o registro docente pode contribuir para uma autoavaliação da prática pedagógica. Ainda se tem como proposta do trabalho, elucidar a relevância da documentação pedagógica, entre elas o registro docente, como material de apoio, comunicação, memória do cotidiano das infâncias e revisitação para construção de novos saberes e fazeres na Educação Infantil. Na elaboração deste artigo, foi feita a fundamentação numa abordagem qualitativa, com análises documentais e tendo como objeto de estudos o caderno de observações diárias da turma de 2 anos de uma instituição de ensino público de Educação Infantil da rede municipal de Magé-RJ. Para dialogar neste artigo, versaremos com as contribuições de Gonçalves e Mendes (2018), Marques e Almeida (2011), Ostetto (2015), Rinaldi (2012), além também dos documentos oficiais da Educação Brasileira e em lócus da Educação Infantil (Lei de Diretrizes e Bases da Educação Nacional 9.394/96 e Diretrizes Curriculares Nacionais para Educação Infantil nº5/17 de dezembro de 2009), respectivamente. Após análise e debates sobre a temática em questão, conclui-se que, a documentação pedagógica legitima a prática docente na Educação Infantil e possibilita uma compreensão dos processos e traz um repensar e refazer diário das ações e avaliações a serem seguidas.

Published: March 2022

O presente artigo dedica-se a refletir sobre o papel do gestor das instituições de educação infantil, considerando as singularidades da primeira etapa da educação básica. Trata-se de um estudo teórico-epistemológico, já que possui características de análise documental e bibliográfica, na medida em que estabeleceu um diálogo com estudos epistemológicos sobre gestão educacional e educação infantil, ressaltando algumas das políticas recentes que se deram em nível nacional e orientam o trabalho administrativo e pedagógico nas instituições públicas de educação infantil, no contexto brasileiro. O texto tem características de pesquisa exploratória, suscitando reflexões acerca da ação de dois gestores da rede pública municipal do Rio de Janeiro. A partir do resultado parcial deste estudo, notamos que esses gestores deslizam para tarefas que burocratizam sua função, pelo viés de uma concepção técnico-cientifica. Em contrapartida, não se atentam para necessidade de atender os princípios democráticos e participativos que norteiam a sistematização da educação pública. Não foi observado, o envolvimento dos gestores na direção de pensar ações formativas que fortaleçam o fazer pedagógico das unidades. Para dialogar neste trabalho, estabeleceu diálogo com as proposições de Heloisa Luck (2013), Sônia Kramer (2007), além dos documentos oficiais como a Constituição Federal, de 1988, a LDBEN, de 1996, o RCNEI, de 1998 e as Diretrizes Curriculares Nacionais para Educação Infantil (DCNEI) de 2009.

Revisiting man-in-the-middle attacks against HTTPS
Authors: Kampourakis Vyron , Kambourakis Georgios , Chatzoglou Efstratios , Zaroliagis Christos
Published: March 2022

A man-in-the-middle (MitM) attack enables threat actors to position themselves in a conversation between two parties. It can be used to eavesdrop on, or impersonate, either of the parties and may enable the perpetrator to steal personal information, including login credentials, payment card data and account details. By leveraging the hijacked information, the attacker can perform an unsanctioned password change, commit identity theft, authorise money transfers, and so on. This article re-examines MitM against HTTPS by both briefly referring to its constituents and assessing its feasibility on modern browsers. We show that under certain circumstances, specific variations of MitM can be effective on all mainstream browsers using cheap, pocket-sized hardware, open-source software and a script-kiddie level of understanding.
How tech hiring is changing

Hiring is always changing, and tech needs and organisations are evolving at lightning speed. The competencies your organisation sought from IT hires in 2017 will probably mean very little now, and the way you spec'd cyber security job roles in 2020 will most likely not be the same in 2022. There's currently a big gap between the number of open job roles and the number of people qualified and applying to fill them.

Many businesses have proven themselves to be resilient and innovative in the light of Covid-19. Any stigma associated with remote working has long since been consigned to history. However, one fly in the ointment can be getting documents signed and/or witnessed, which has thrown a light on electronic signatures. E-signatures can, when used appropriately, provide a simple and elegant solution to an issue that has been exacerbated by Covid but which will continue to be an issue in the post-pandemic world.
Diabetes and periodontal disease
Authors: King Rhydian , Chasma Farida
Published: March 2022

Diabetes and periodontal disease have been shown to have a bidirectional relationship in which poor outcomes in one often translate to poor outcomes in the other. Dentists may be valuable in providing an additional diabetes screening service for patients presenting with symptoms of chronic periodontitis. Similarly, diabetic patients should be encouraged to seek guidance from dental professionals for the detection of undiagnosed chronic periodontitis. Improving communication between the two professions may improve patient outcomes in both diseases, where periodontal assessment with a dentist forms a part of a diabetic patient’s annual screening. This article aims to highlight the relationship between the two diseases and the overlap between professions.
Measurement of visibility and phase steps of a static wind imaging interferometer assisted by deep learning
Authors: Wang Yanqiang , Zhang Chunmin , Chen Zeyu , Sun Yongqiang , Zhang Pengju
Published: March 2022

In a static wind imaging Michelson interferometer we developed, one of the Michelson mirrors is divided into four quadrants, with coatings on the quadrants that provide small phase steps from one quadrant to another, realizing the four simultaneous sampling of the interferogram. Restricted by the coating process and interferometer adjustment, the instrument visibility and phase steps of the four quadrants will deviate from the design value. In the actual passive detection of the atmospheric wind field, quasi-real-time calibration is required, and the calibration will also be affected by the instrument noise. In this paper, we propose a deep-learning-based denoising algorithm that can quickly denoise the wind interferogram with no need to adjust parameters, combined with conventional least-squares fitting cosine curves to obtain the visibility and phase steps of four quadrants from a series of interferograms with varying phase differences. The proposed algorithm framework is verified by experiment, and the measurement of visibility and phase steps of the wind field interferogram is efficiently realized. It can provide a reference for the visibility and phase steps measurement of the wind imaging interferometer and may have applications in wind imaging interferometer calibration.
Power equalization method of a DFB fiber laser sensor array
Authors: Xu Dan , Huang Jun Bin , Wu Jun , Gu Hong Can , Liu Wen
Published: March 2022

To reduce the output power ununiformity mainly caused by the exponential attenuation of pump power in a distributed feedback fiber laser (DFB FL) sensor array, a power equalization method based on array structure optimization is proposed. By analyzing the influencing factors of the output power flatness of the array, an output power prediction model of a DFB FL wavelength division multiplexing (WDM) array is established, and the standard deviation coefficient of the output power is proposed as the main evaluating indicator for assessing the output power flatness. An array structure optimization scheme based on the simulated annealing algorithm is designed, and the optimized array structure of the 64-element DFB FL sensor array is achieved. The results show that the power fluctuation of the optimized array is significantly reduced from universal 5–10 dB to smaller than 2.6 dB, while the performance of the DFB FL sensor array is improved with better noise floor and increased multiplexing capacity, as well as improved array design efficiency.
Ion beam figuring strategy for aluminum optics with minimal extra material removal
Authors: Guan Chaoliang , Du Chunyang , Dai Yifan , Hu Hao
Published: March 2022

With the application spectrum moving from infrared to visible light, aluminum optics with complex forms are difficult to fabricate by the majority of existing processing methods. Possessing the highest machining precision and low processing contamination, ion beam figuring (IBF) is a better method for fabrication of aluminum optics. However, the surface roughness deteriorates with the removal depth during IBF. In this study, the extra material removal during the IBF process is studied systematically. Extra material removal consists of two parts, determined by the convolution process and the limitation of the dynamic performance of machining tools. Extra material removal can be reduced by filtering out the surface residual error with a spatial frequency higher than the cut-off frequency and reducing the iterations of the machining process. Then, the executability of the dwell time matrix and the figuring ability of the removal function are analyzed. Adjusting the working parameters (volume removal rate) reduces the requirements for dynamic performance of machining tools. Finally, a minimal material removal processing strategy for aluminum optics based on power spectral density analysis and a spatial frequency filtering method is proposed. A simulation is conducted to verify the feasibility of the proposed strategy. With the same final precision (59.8 nm PV and 4.4 nm RMS), the maximum material removal decreases nearly 36 nm by applying the strategy, which reduces roughness nearly 10 nm. This study promotes the application of IBF in the field of aluminum optics fabrication as well as improves the machining precision of aluminum optics.

Rabies transmitted by wildlife is now the main source of human rabies in the Americas. The common marmoset, Callithrix jacchus, is considered a reservoir of rabies causing sporadic and unpredictable human deaths in Brazil, but the extent of the spillover risk to humans remains unknown. In this study, we described the spatiotemporal dynamics of rabies affecting C. jacchus reported to Brazil’s Ministry of Health passive surveillance system between 2008 and 2020, and combined ecological niche modelling with C. jacchus occurrence data to predict its suitable habitat. Our results show that 67 outbreaks (91 cases) of rabies affecting C. jacchus were reported by 41 municipalities between January 2008 and October 2020, with a mean of 5 outbreaks/year [range: 1–14]. The maximum number of outbreaks and municipalities reporting cases occurred in 2018, coinciding with higher surveillance of primate deaths due to Yellow Fever. A mean of 3 [1–9] new municipalities reported outbreaks yearly, suggesting potential spatial expansions of the C. jacchus variant in northeastern Brazil and emerging rabies spillover from vampire bat Desmodus rotundus to C. jacchus in the north and south. Outbreaks were concentrated in the states of Ceará (72%) and Pernambuco (16%) up to 2012, but are now reported in Piauí since 2013, in Bahia since 2017 (D. rotundus’ antigenic variant, AgV3) and in Rio de Janeiro since 2019 (AgV3). Besides confirming suitable habitat for this primate in the northeast and the east coast of Brazil, our Maximum Entropy model also predicted suitable habitat on the north and the west states of the country but predicted low habitat suitability among inland municipalities of the Caatinga biome reporting rabies. Our findings revealed new areas reporting rabies infecting C. jacchus, highlighting the need to implement strategies limiting spillover to humans and to better understand the drivers of C. jacchus rabies dynamics.

Background

The focus on laboratory-based diagnosis of coronavirus disease 2019 (COVID-19) warrants alternative public health tools such as rapid antigen tests. While there are a number of commercially available antigen tests to detect severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), all cross-react with the genetically similar SARS-CoV-1 or require an instrument for results interpretation.

Methodology/Principal findings

We developed and validated rapid antigen tests that use pairs of murine-derived monoclonal antibodies (mAbs), along with gold nanoparticles, to detect SARS-CoV-2 with or without cross-reaction to SARS-CoV-1 and other coronaviruses. In this development, we demonstrate a robust antibody screening methodology for the selection of mAb pairs that can recognize SARS-CoV-2 spike (S) and nucleocapsid (N) proteins. Linear epitope mapping of the mAbs helped elucidate SARS-CoV-2 S and N interactions in lateral flow chromatography. A candidate rapid antigen test for SARS-CoV-2 N was validated using nasal swab specimens that were confirmed positive or negative by quantitative reverse-transcription polymerase chain reaction (RT-PCR). Test results were image-captured using a mobile phone and normalized signal pixel intensities were calculated; signal intensities were inversely correlated to RT-PCR cycle threshold (Ct) value.

Conclusion/Significance

Overall, our results suggest that the rapid antigen test is optimized to detect SARS-CoV-2 N during the acute phase of COVID-19. The rapid antigen tests developed in this study are alternative tools for wide scale public health surveillance of COVID-19.

Conjunctival squamous cell carcinoma (SCC) is the most common ocular surface neoplasia. The purpose of this retrospective study was to examine the role of regulatory T cell (Treg) activity in tumor immunity and investigate the tumor microenvironment as a new treatment focus in conjunctival SCC. Cancer progression gene array and immunohistochemical analyses of FOXP3 as a Treg marker, CD8 as a tumor-infiltrating lymphocyte marker, and CXCR4 expression on activated Tregs were conducted in a series of 31 conjunctival SCC cases. The objective was to investigate the immunoreactive response in tumor cells and stromal cells in the cancer microenvironment. The stroma ratio in tumor cells was investigated by monitoring α-smooth muscle actine (SMA) expression between carcinoma in situ (Tis) and advanced carcinoma (Tadv) (P<0.01). No significant change in PD-L1 expression was observed in this study (P= 0.15). Staining patterns of FOXP3, CD8, and CXCR4 were examined separately between tumor cells and stromal cells in SCC tumors. Differences in staining of FOXP3 in Tregs and CD8 in tumor-infiltrating lymphocytes in tumor stroma in the Tis group were observed compared with the Tadv group (eachP<0.01). In addition, double immunostaining of CXCR4/FOXP3 was correlated with progression-free survival (P= 0.049). Double immunostaining of CXCR4/FOXP3 correlated with American Joint Committee on Cancer T-stage, independent of age or Ki67 index (P<0.01). Our results show that FOXP3 and the CXCR4/FOXP3 axis are important pathologic and prognostic factors of ocular surface neoplasia, including SCC. The tumor microenvironment of conjunctival SCC should be considered in the future development of treatment options.
Structural shifts in food basket composition of rural and urban Philippines: Implications for the food supply system

Empirical evidence on the responsiveness and sensitivities of food consumption to its drivers is vital for conducting economic studies. Despite recent attempts to provide such estimates, much empirical work remains to be done considering the prevailing shifts in consumption trends in the Philippines. Price and expenditure elasticities are estimated for seven food categories for rural and urban Filipino households, using Stone–Lewbel (SL) price indices and the quadratic almost-ideal demand system (QUAIDS) model. We used multiple years (2006, 2009, 2012, 2015, and 2018) of the Philippines Family Income and Expenditure Survey (FIES) to estimate the food demand system. The results show that rice is a normal good for most households, particularly for rural consumers. However, it is an inferior good for the top 30% of rural Filipinos and the top 40% of urban Filipinos. As income increases, such wealthy households tend to replace their rice-dominated diet with nutrient-dense food products. Female-headed households, younger households, and households with educated members consume significantly more animal proteins such as meat and dairy products.

The present study examined the association between risk perception and travel satisfaction related to the use of public transport (PT) during COVID-19 pandemic in Turin, Italy. A total of 448 PT users took part in an online survey conducted from January to March 2021. It investigated safety and risk perception related to the use of PT, and the users’ subjective experience, measured through the Satisfaction with Travel Scale (STS). These perceptions were compared for three time scenarios: before the pandemic, during the pandemic, and in the future at the end of the pandemic emergency. Results showed that COVID-19 influenced respondents risk perception both during the pandemic and in their projections about the future, especially for females. The risk of contagion from COVID-19 is perceived as higher inside a PT vehicle than in the adjacent/waiting spaces. Regarding travel satisfaction, the overall scores of the STS indicated that the pandemic has impacted reported well-being while travelling, both now and in the future. The dimension of activation shifted towards the negative pole and did not indicate a return to risk perception before the pandemic levels at the end of the crisis (especially for females). Respondents reported a significant decrease in their level of pleasure and satisfaction during the pandemic, but expect that in the future these levels will go back to the levels previously experienced. Regarding travel satisfaction, PT users aged 36 to 50 years reported the highest level of satisfaction, while younger users (18 to 35 years) reported the lowest degree of satisfaction in all three time scenarios. Overall, the results clearly pinpoint that health-related perceived risk is becoming a key determinant for PT use. Within this context, different dimensions of travel satisfaction proved to be impacted differently by the pandemic, for both current and future scenarios.
Salient alternatives facilitate implicatures
Authors: Bott Lewis , Frisson Steven
Published: March 2022

Sentences can be enriched by considering what the speaker does not say but could have done, thealternative. We conducted two experiments to test whether the salience of the alternative contributes to how people derive implicatures. Participants responded true or false to underinformative categorical sentences that involved quantifiers. Target sentences were sometimes preceded by the alternative and sometimes by a control sentence. When the target was preceded by the alternative, response times to implicature responses were faster than when preceded by the control sentence. This suggests that (1) alternative salience influences higher-level reasoning (2) the cost of deriving implicatures in sentence verification paradigms is due in part to low alternative salience.
