Por uma Formação Matemática Orientada pela Prática Docente na Educação Básica
Authors: Elias Henrique Rizek
Published: August 2021

Atualmente, há um considerável número de pesquisas no âmbito da Educação Matemática que discutem, com base na prática docente, aspectos do conhecimento matemático específico para o ensino na Educação Básica. Cada vez mais, essas pesquisas têm representado uma maior compreensão sobre a constituição da matemática escolar e, por consequência, proporcionado maior clareza sobre uma formação matemática adequada ao futuro professor. Entretanto, nem sempre a prática docente e as pesquisas sobre essa prática têm sido valorizadas enquanto parâmetro para se pensar a formação matemática de futuros professores. O que tem nos impedido de caminhar na direção de uma formação com base na prática profissional do professor? O presente artigo, que se caracteriza como um ensaio teórico, visa problematizar alguns discursos e tecer reflexões que vão na direção de mostrar como uma desvalorização do professor da Educação Básica também pode ser retratada a partir da matemática presente na formação inicial desse professor.

MathTASK é um programa de pesquisa e desenvolvimento que engaja professores de matemática em situações de sala de aula desafiadoras e altamente contextualizadas na forma de tarefas (chamadas de mathtasks). As respostas de professores às tarefas revelam seus discursos matemáticos e pedagógicos e abrem oportunidades para articular, considerar e reconstruir tais discursos. As tarefas foram usadas como instrumento de pesquisa e também de formação de professores e desenvolvimento profissional no Reino Unido, na Grécia e no Brasil. Neste artigo, apresentamos o programa MathTASK e um exemplo de mathtask. Em seguida, apresentamos um resumo dos construtos teóricos que emergiram na análise dos dados do programa MathTASK. Então, indicamos os princípios gerais do uso de mathtasks na pesquisa e formação de professores e damos quatro exemplos dos princípios, cada um dirigido a diferentes aspectos do ensino e da aprendizagem de matemática, e cada um desenvolvido tendo em mente níveis educacionais e contextos. Concluímos com observações sobre os benefícios de usar mathtasks como uma forma de estimular e facilitar reflexões de professores de matemática sobre suas práticas.
Por uma Matemática Problematizada: as Ordens de (Re)Invenção
Authors: Giraldo Victor , Roque Tatiana
Published: August 2021

Abrimos este ensaio contrastando duas formas de exposição da matemática: a ordem da estrutura, corresponde à organização segundo implicações lógicas e critérios de legitimação aceitos hoje; e as ordens de invenção, referenciadas nos diversos caminhos de produção de saberes mobilizadas nas práticas hoje identificadas como matemáticas. Relacionamos essas visões com uma oposição entre duas perspectivas para a matemática, determinadas por ontologias radicalmente distintas da categoria problema. Na primeira, teoremas são considerados como categoria central e problemas como estados de deficiência provisória. A segunda, que chamamos de matemática problematizada, entende problemas com natureza transcendente às soluções, e os considera como único a-priori da matemática. Discutimos reverberações dessas perspectivas no ensino de matemática, em dimensões epistemológicas da matemática e das práticas docentes. Reivindicamos deslocamentos nos sentidos de “erro” e “não-entendimento” como gradações do conhecimento, situando-os como possibilidades de lançar outros entendimentos, que produzem, na incompletude e no inacabamento, as ordens da (re)invenção.
A Liga das Nações em tempos de crise
Authors: Queiroz de Campos Filipe
Published: August 2021

Após a Primeira Guerra Mundial, o Brasil pleiteou um assento permanente no Conselho de Segurança da Liga da Nações, organização que buscava construir uma diplomacia multilateral, para que se evitasse novas guerras mundiais. A diplomacia brasileira na Liga das Nações ficou conhecida pela historiografia por apresentar decisões nada diplomáticas. O Brasil vetou a entrada da Alemanha na Liga, causando desconforto internacional, bem como exigiu o assento permanente como condição para continuar na organização, se retirando definitivamente da Liga em 1926. Sobre as razões por trás dessas decisões, contudo, há muito que se debater. Até então, a historiografia vinha apontando que foram decisões tomadas devido à personalidade impetuosa e intransigente do presidente Arthur Bernardes. Novas pesquisas, contudo, demonstram que há razões mais complexas por trás das decisões de Bernardes. Essas razões se ligam às relações de poder entre o Presidente e seus diplomatas. Nesse artigo, analisaremos essas relações de poder entre Arthur Bernardes e seus informantes internacionais, por meio da categoria de intelectuais mediadores de Ângela de Castro Gomes, para investigarmos mais detidamente o processo de tomada de decisões que levaram o Brasil a sair da Liga das Nações.

Published: August 2021

Con el objetivo de identificar la composición corporal y aptitud física en jugadoras de baloncesto universitarias, se tomaron mediciones básicas de edad, peso, talla, envergadura. Fueron evaluados pliegues cutáneos de tricipital, subescapular, bicipital, cresta iliaca, supraespinal, abdominal, muslo frontal, pantorrilla medial. En perímetros fue contabilizado brazo relajado, brazo contraído, cintura, cadera, muslo medial y pantorilla. En diámetros consideramos humero, muñeca y fémur. Las técnicas de evaluación estuvieron sujetas a los protocolos de la International Society for the Advancement of Kinanthropometry (ISAK). El test de la composición corporal se hizo por Bioimpedancia (BIA) con báscula In-body 770, También realizamos pruebas de potencia en piernas, velocidad de desplazamiento, capacidad de reacción y VO2máx. Los resultados demostraron un somatotipo mesoendomórfico con 5,94±1,42; 4,38±1,26; 2,05±0,95. Se encontraron valores bajos en salto, capacidad de reacción, velocidad de desplazamiento y VO2máx. Conclusiones: Las jugadoras reflejaron un desempeño bajo de acuerdo a las características del baloncesto; el somatotipo con dominancia hacia la endomorfia también indica una constitución poco recomendable en los deportes de colaboración y oposición. El estudio de caso de esta investigación permite una aproximación a conocer datos que ayuden a contextualizar el deporte en México.

Published: August 2021

O envelhecimento é acompanhado por alterações fisiológicas e surgimento de doenças crônicas que podem propiciar declínios na funcionalidade para as atividades básicas (ABVDs) e instrumentais de vida diária (AIVDs). Nesse contexto, este estudo teve como objetivo identificar a associação entre a dependência funcional nas atividades básicas e instrumentais de vida diária e morbidades referidas em idosos. Estudo epidemiológico populacional, transversal, realizado com 258 idosos de Aiquara-BA. As informações sociodemográficas, comportamentais e sobre morbidades autorreferidas foram obtidas por um instrumento próprio. O nível de atividade física foi mensurado a partir do International Physical Activity Questionnaire. A dependência funcional foi identificada pela escala de Katz e escala de Lawton e Brody. Nas análises, adotou-se o teste Qui-quadrado de Pearson e a regressão hierárquica de Poisson, com estimativa robusta e cálculos de razão de prevalência (RP) e intervalos de confiança (IC) de 95%. Observou-se prevalências de dependência nas ABVDs (12,8%) e AIVDs (31,8%). Verificou-se, também, que os idosos que já tinham apresentado infarto agudo do miocárdio (RP: 2,57; IC95%: 1,18-5,59), acidente vascular encefálico (RP: 3,15; IC95%: 1,71-5,81) e os que tinham Alzheimer (RP: 4,76; IC95%: 3,02-7,50), demonstraram maior probabilidade para dependência nas ABVDs. Além disso, os idosos com Alzheimer cursaram com 1,30 (IC95%: 1,10-3,30) vezes maior probabilidade de serem dependentes nas AIVDS. As evidencias do presente estudo demonstraram que o infarto agudo do miocárdio e o acidente vascular encefálico estiveram associados à dependência nas ABVDs. Além disso a doença de Alzheimer mostrou-se associada à dependência nas ABVDs e AIVDs.

O objetivo do presente estudo foi avaliar a relação entre redes sociais e fatores associados à insatisfação com a imagem corporal, em estudantes durante o período de isolamento social causado pela pandemia de COVID-19. Realizou-se um estudo observacional, do tipo transversal, cuja amostra foi constituída por estudantes do ensino médio, de ambos os sexos, de uma escola pública do município de Pinheiral, Rio de Janeiro. A coleta de dados foi realizada nos meses de Junho e Julho de 2020 e utilizou-se como instrumento um questionário online, constituído por perguntas abertas e fechadas. Foram avaliadas características demográficas, prática de exercícios físicos, práticas alimentares, utilização das redes sociais e nível de satisfação com a imagem corporal, pela escala de silhuetas de adolescentes. Participaram do estudo 69 estudantes, dentre os quais 79,7% (n=55) declararam insatisfação com a imagem corporal, 47,8% (n=33) praticavam exercícios físicos regularmente, 29% (n=20) realizavam dietas restritivas, 33,3% (n=23) apresentavam sintomas de transtornos alimentares e 98,6% (n=68) utilizavam, frequentemente, as redes sociais. Dentre os insatisfeitos com a imagem corporal, 75% (n=39) do sexo feminino e 46,2% (n=7) do sexo masculino afirmaram que as redes sociais influenciam a autopercepção corporal (p=0,04). Concluiu-se que as redes sociais influenciaram negativamente a percepção da imagem corporal, em adolescentes de ambos os sexos, durante o isolamento social devido à pandemia por COVID-19.
Corpo, beleza e juventude na contemporaneidade: apontamentos reflexivos
Authors: Gama Cláudio Oliveira da , Gama Gláucio Oliveira da , Pires Valéria Nascimento Lebeis , Braga Jose Ueleres , Maciel Elvira Maria Godinho de Seixas
Published: August 2021

A contemporaneidade é marcada pela era do corpo utilizado como ferramenta do consumismo. Por intermédio de hábitos e práticas corporais, estilos de vida se propagam pelos veículos de comunicação midiáticos. Neste contexto, jovens constituem o grupo mais vulnerável a ser influenciado, sendo compreensível seus desejos em fazerem parte de grupos e terem suas identidades aceitas socialmente. O texto apresenta uma reflexão dialógica acerca do culto ao corpo, beleza e juventude na sociedade contemporânea. No cenário atual, o corpo ocupa destaque muito além de qualidades requisitadas em outras épocas,com a compulsão cotidiana por atributos da beleza jovem, há uma vontade presente de manter e adequar-se a aparência vigente, bem como uma inovação contemporânea em retardar o processo natural da vida: o envelhecimento do corpo. Nesse caso, a tentativa é de esconder características físicas indesejáveis assumindo o estereótipo corporal jovem, da beleza eterna. Esse parece ser o desejo contemporâneo, que o tempo do corpo pare e ceda aos rituais da beleza. Como conclusão, percebe-se que o estado jovial, que outrora delimitava uma fase da vida, hoje, por meio de valores socioculturais, se transforma em símbolo, tamanha relevância apresentada no presente, mas que apresenta inclinações preocupantes para o campo da saúde mental, notadamente na insatisfação corporal.

Navigating Methodological Concerns at the Data Collection Stage: Lessons from a Qualitative Indian-Irish Adoption Study
Authors: Mitra Sahana , O'Brien Valerie
Published: August 2021

This paper was written to describe the experiences of the researchers in designing cross-cultural research on the culturally sensitive topic of adoptive parenthood, a field in which there is a dearth of literature. Taking the experience and examples from an Indian-Irish study on domestic adoptive parenthood, the paper details the steps as to how the researchers used their own relationship with adoption, and the different cultural contexts to which they belonged, as a starting point in designing and implementing this research. The discussion utilizes a conceptual framework involving insider-outsider positioning, reflexivity and five philosophical assumptions (ontology, epistemology, methodology, axiology, and rhetoric) to show how cross-cultural research can be negotiated. Through the research design and data collection stage, researchers' understanding about themselves and about the adoption process in the two countries, is used as a backdrop for the exploration. While various deliberations and negotiations between the researchers are described, the paper also shows the differences and methodological concerns that can be steered through inter-cultural territory, where reflexivity is central to all stages of the endeavor. These processes and reflections are summarized in this paper, with recommendations for students and academics to promote the discussions around the design of qualitative cross-cultural work.
The Challenges of Implementing Action Research in a Divided Context: A Field Account
Authors: Akande Olubunmi
Published: August 2021

Action research is mainly concerned with the entrenchment of social change through social interventions that involves the beneficiaries as key participators. The study documents the experience of the researcher in conducting action themed research in two adversarial communities in North-Central Nigeria. The core goals of the study are to draw attention to the usefulness of this approach for peacebuilding research and to also shed light on some of the complexities associated with this kind of research. A research diary was employed to document events and reflections as they unfolded during the fieldwork. A combination of a harsh social climate and the invasive nature of the research functioned to deepen the conventional limitations associated with projects of this nature in the research settings. Challenges were encountered in the areas of access to information, researchers’ identity, and emotive interaction with the process. Disruptive difficulties were also experienced during the intervention stage of the research where emerging developments in the social-political climate in both communities had drastic effects on the research. The navigation of these challenges was facilitated by a step-by-step application of simple methodological and practical principles that facilitated data collection without compromising the scientific rigour of the study. The primacy placed on values such as sensitivity, resilience, genuine commitment for the welfare of the communities was also instrumental for actualising the research goals. The study recommends the inclusion of non-formal techniques such as observation and informal conversations in data collection processes in conflict communities. To optimise productivity, change oriented researchers may benefit from a preliminary assessment of the potential methodological and practical difficulties inherent in the research context.
Archaeometallomics as a Tool for Studying Ancient Ceramics
Authors: Li Li , Feng Xiangqian
Published: August 2021

In this paper, the concept of archaeometallomics is put forward to study the role of metal elements in cultural relics. An example is the influence of metal elements in the identification of their origin, dating, authenticity and the technology used for the production of ancient ceramics. This analysis also provides the social and cultural connotations of the development process of that time and shows that there is a close relationship between the rich glaze varieties and the metal elements in porcelain. The application of different analytical techniques in studying metallic elements in ancient ceramics is also briefly summarized. The construction of a metal element composition database and the related questions in the glaze color-forming mechanism of ancient relics should be considered an important research direction for future works.

Published: August 2021

The novel coronavirus (COVID-19), identified within the Wuhan, Hubei Province of China in November 2019, needs distinct attention because of its fatal nature. The spreading of any infectious diseases is generally prevented by quarantine and containment or locking down of the populations in danger. Countries suffering from COVID-19 are declaring the country lockdown and restricting public movement. India also has declared full lockdown and restricted public movement to a large extent. Such drastic steps have a severe psychological impact on populations. Being locked up for weeks in a very confined space with the same group of individuals being depressed, nervous, and tired, which is further aggravating various domestic and interpersonal issues. A web-based survey was formed which supported a cross-sectional sampling method and collected data across different working-class population groups in India. The responders had a beginner level of knowledge about the COVID-19 infection and adequate knowledge about its preventive aspects was unknown. Results indicate that 13% of the respondents experienced severe anxiety, 11% moderate anxiety, and 28% are mildly anxious. The results suggest that governments should find effective ways to disseminate unbiased COVID-19 knowledge to reduce population insecurity and provide the best mental equipment to cope with the pandemic.

A descriptive research methodology utilized to identify the success opportunity of applying such framework in SEKEM community by questionnaire survey designed for such purpose on a convenient sample of 114 respondents. It was found that applying digital currency in such community will lead to explore opportunities to reduce the cost of living and education for community respondents and also add value to SEKEM as a special business pattern.
Location-Based Mobile Community Using Ants-Based Cluster Algorithm
Authors: Srisa-an Chetneti
Published: August 2021

A location based service (LBS) is widely used on modern smartphone around the world asits built-in features. Each smartphone can access a google API or map. People can therefore share their location (latitude and longitude) among friends. Many LBS spots can easily form “location based mobile community (LBMC).” Since the nodes are mobile, the community group changes dynamically and is unstructured. Ant-based clustering algorithm is a special kind of optimization technique which is highly suitable for finding the adaptive clustering for volatile networks. This Paper Aims To form a location based mobile community (LBMC) by using Ant-based clustering algorithm. Due to the mobile type community, a vanishing community problem is also stated in this paper. Instead of redo a whole algorithm again, we modify an original algorithm by applying a pheromone concept to handle a change. Our algorithm is named as ABCA & VP which stands for Ant-Based Clustering Algorithm with Vanishing problem. More than 5,000 samples from their latitude and longitude coordinates in Thailand. From an experiment, K-means clustering work well in small data size and low number of clusters. In Small size of data between 50 and 1000, our algorithm runs battery when a number of clusters reach 15 clusters. In a big data size (between 1,000 and 5,000 samples), our algorithm outperforms K-means clustering when a number of clusters reach 20 clusters.

This study aims to analyze the effect of profitability and free cash flow on capital structure with firm size as a moderating variable. The population in this study is the food and beverage sub-sector company on the IDX in 2011-2018. The sample used was 9 companies, which were selected based on the purposive sampling method. The data analysis technique used is multiple linear regression analysis and residual test.The results showed that the profitability variable had no effect on capital structure. While the free cash flow variable has a positive and significant effect on capital structure. In the moderation test with the residual test approach, firm size does not moderate the relationship between profitability and free cash flow on the capital structure

Published: August 2021

New data are presented on the formation conditions and ages of the reduced intrusion-related Au mineralization of the Vetrenskaya area in the Central Kolyma region. The mineralization is predominantly confined to intersections of Late Jurassic minor intrusive bodies and NE-trending fracture systems and is represented by zones of thin quartz veinlets with sericite-quartz halos. The major ore mineral is gold-bearing arsenopyrite (up to 10%), while minor minerals are represented by lellingite, pyrite, chalcopyrite, and pyrrhotite. Microscopic native gold of a low fineness is paragenetically associated with bismuth minerals (bismuthine, native bismuth, andtellurides of Bi and Au), forming microinclusions (1–10 μ) in the arsenopyrite. Isochronous Re-Os age of the goldbearing arsenopyrite is 137–117 Ma, which suggests the mineralization was formed significantly later than the hosting granitoids (147–153 Ma). The reduced intrusionrelated Au ore deposit was formed at shallower depths in comparison with orogenic Au deposits, and at lower temperatures in comparison with rare metal (W, Mo) ore deposits.
Nickel anomalies and gold-quartz mineralization in dunite-harzburgite massifs of the Pervomaisko-Verkhoturinskaya area, Central Urals
Authors: Motov Andrey , Malakh Yury , Voropaev Ilya
Published: August 2021

Along with some gold-quartz deposits hosted by dunite-harzburgite massifs elsewhere in the Urals, elevated Ni concentrations were revealed within the ore field of the Anna gold-(sulfide)-quartz deposit localized in weathered oxidized dunites and harzburgites of the Pervomaisky complex (συO2p) in the Pervomaisko-Verkhoturie district of the Central Urals. The spatial association of Au and Ni concentrations in dunites-harzburgites may be attributed to a partial inheritance of Ni-controlling tectonic dislocations by those hosting gold mineralization. Therefore, the combination of halos of Ni and Au concentrations in dunite-harzburgite massifs is a favorable indicator of areas prospective for discovery of goldquartz mineralization.
The New National Headache Management System is an easy solution to provide more efficient and evidence-based headache services
Authors:   Torbay and South Devon NHS Foundation Trust, Gordon Alexander , Lashley Daniel ,   University Hospitals Plymouth, Weatherby Stuart ,   University Hospitals Plymouth
Published: August 2021

Headaches make up 30% of all Neurology outpatient consultations.1 There is distinct variability in the management of headaches by Neurologists, leading to unnecessary disparities in the standard of care and likelihood of response between patients. A significant proportion of patients with headache diagnoses do not receive the evidence-based treatments recommended in national or international guidelines,2 and substantial numbers of patients are not receiving preventive therapies.3  Ziegeler et al. found that a third of patients reporting to a tertiary headache centre had not received preventive therapy in line with guidelines, and half had never been prescribed a preventive treatment.2 Considering that 46% of the global adult population are estimated to have a headache disorder,4 this lack of a consistent, evidence-based approach is somewhat incongruent with the patient socio-economic impact. It is probable that lack of adherence to current headache guidelines is a multi-faceted issue. This variation in treatment (and therefore patient outcome), although unexplored,2 is not likely to be a simple educational issue. To add to this, an educational approach, in the form of seminars and workshops, does not have entirely positive evidence to support its use in implementing changes to patient care.5  It seems more probable that there are also structural issues within the health service that in some way preclude patients with headache disorders from gaining appropriate care.  For example, using only doctors to care for patients with such a common condition may cause bottle-necking in access, and may not be an appropriate use of clinical resource.  The current context of a global pandemic has shown us the importance of using the skillsets of all NHS staff working together for patient care.  For headache care this could involve greater use of nursing colleagues or allied health professionals such as Pharmacists. To facilitate such an aim, an easily used and standardised approach is essential. We believe that the guidelines from the British Association for the Study of Headache (BASH),6 could facilitate such an approach.
THE POLICY OF ARABIZATION OF EDUCATION IN ALGERIA BETWEEN LINGUISTIC PLANNING AND SOCIAL REALITY: ARABIZATION OF HIGHER EDUCATION AS A MODEL
Authors: DJABALLAH Zahia
Published: August 2021

This article is concerned with research on the sociolinguistic reality in Algeria, by studying one of its issues, which is the issue of the arabization of education. And if the linguistic policy is affected and influenced by social life, then planning in arabization has a relationship with social reality. Therefore, our research aimed at studying the relationship between the applied arabization policy and the linguistic requirements of social reality. The most important results reached were the inconsistency of the applied arabization policy with the linguistic base established by the colonial authority , which continued after independence, and led to the emergence of fundamental problems, resulting from the total arabization of the basic and secondary training and some specializations in higher education. So that students in arabized disciplines largely lost control over the foreign language, which is a prerequisite for contemporary changes and for national needs that require control over bilingualism. As for those enrolled in specializations that depend on the French language, they found difficulty with the language of formation, because their basic formation was in the Arabic language.

ORGANIZATIONAL CHALLENGES FACING SCHOOL ADMINISTRATORS IN TULKAREM DIRECTORATE FROM THE POINT OF VIEW OF THE SCHOOL PRINCIPALS THEMSELVES
Authors: HOSSIN Mahmoud Jameel Mahmoud
Published: August 2021

The study aims to identify the organizational challenges facing school administrators in Tulkarem directorate from the point of view of the school principals themselves. In addition, it shows the impact of the variables related to the gender, qualification, experience and geographical location on organizational challenges. An online questionnaire was used as a tool to collect data. The study sample consisted of 138 male and female principals selected randomly. Moreover, the descriptive analytical approach was used to analyze the data through the SPSS statistical analysis software, and to draw the conclusions. The results of the research have shown that the section stating the principals' lack of familiarity with new developments in management science and the lack of valid basic data needed to prepare plans was great. In addition, the arithmetic average was very big for the sections stating the following: the proliferation of generalizations and decisions in such a way which makes following up their implementation take time and effort at the expense of other work, obligating schools to follow rules and instructions to the letter, poor cooperation between the school administration and senior levels of administration, and the regulations established on ideal grounds are difficult to be realistically complied with at schools. Moreover, the results have indicated that there were no individual differences in the most common organizational administrative challenges among public school principals in Tulkarem governorate according to gender, specialization, qualification and years of experience.

Published: August 2021

Este artigo objetiva investigar e compreender o governamento da infância voltado para a Educação Infantil por meio das definições propostas pela Base Nacional Comum Curricular. Justifica-se este estudo por entender tal documento normativo como orientador para uma formação massificante e predefinida em etapas que regulam a ação docente. Metodologicamente, esta pesquisa caracteriza-se como pensada no campo das Ciências Humanas, sendo de abordagem qualitativa, dialogando com: Foucault, 2008, 2010), Bujes (2002), Veiga-Neto e Saraiva (2011).  Foi realizada uma análise documental, tomando como material analítico a Lei de Diretrizes e Bases; as Diretrizes Curriculares Nacionais para a Educação Infantil, mas primordialmente a Base Nacional Comum Curricular, no tocante à Educação Infantil. Análises dos documentos demonstram um retorno a antigas concepções preparatórias da Educação Infantil para o Ensino Fundamental, desconsiderando os processos regionais e culturais vividos por múltiplas infâncias.
Occupational Reflection as Intervention in Inpatient Psychiatry
Authors: Bailliard Antoine , Schafer Zachary , Hart Lauren
Published: August 2021

Importance: The recovery model in mental health involves person-driven care and informed decision making to enhance engagement in meaningful activities and inclusion in society. To facilitate the recovery process, occupational therapy practitioners must support their clients in understanding how their participation in meaningful occupation is intimately related to their health and well-being.

Objective: To explore whether engaging in an occupational reflection intervention on an inpatient psychiatric unit can support the recovery of adults living with serious mental illness (SMI).

Design: Using a phenomenological design, we conducted semistructured interviews to assess whether participation in an occupational reflection intervention supported recovery.

Setting: An inpatient psychiatric unit at a university medical center.

Participants: We recruited 10 adults living with SMI using purposive sampling.

Intervention: Participants engaged in a structured occupational reflection intervention using the Occupational Experience Profile (OEP). The OEP is a time-use diary that captures respondents’ subjective experiences of pleasure, productivity, restoration, and connection in relation to their participation in occupations over 24 hr. Study participants engaged in collaborative analyses regarding their OEP results to explore their subjective experiences in relation to their occupational participation.

Outcomes and Measures: Participant self-report during interviews.

Results: Engaging in structured reflection affected participants’ experiences of recovery by promoting insight into and awareness of how occupations affect mental health, encouraging positive reframing of occupational experience, and facilitating identification of strategies to support recovery and meaningful participation after discharge.

Conclusions and Relevance: Occupational reflection can promote the recovery of adults living with SMI.

What This Article Adds: A structured occupational reflection intervention can help adults living with SMI in inpatient psychiatric units to understand the close relationship between their participation in occupations and their health. This process provides valuable insight to clients regarding how to support their recovery through engagement in meaningful occupation.
Human-System Interface with Explanation of Actions for Autonomous Anti-UAV Systems
Authors: Kontos John
Published: August 2021

Research on explanation is currently of intense interest as documented in the DARPA 2021 investments reported by the USA Department of Defense. An emerging theme for explanation techniques research is their application to the improvement of human-system interfaces for autonomous anti-drone or C-UAV defense systems. In the present paper a novel proposal based on natural language processing technology concerning explanatory discourse using relations is briefly described. The proposal is based on the use of relations pertaining to the possible malicious actions of an intruding alien drone swarm and the defense decisions proposed by an autonomous anti-drone system. The aim of such an interface is to facilitate the supervision that a user must exercise on an autonomous defense system in order to minimize the risk of wrong mitigation actions and unnecessary spending of ammunition.
Novel Position Estimation using Differential Timing Information for Asynchronous LTE/NR Networks

Published: August 2021

Positioning techniques have been a common objective since the early development of wireless networks. However, current positioning methods in cellular networks, for instance, are still primarily focused on the use of the Global Navigation Satellite System (GNSS), which has several limitations, like high power drainage and failure in indoor scenarios. This study introduces a novel approach employing standard LTE signaling in order to provide high accuracy positioning estimation. The proposed technique is designed in analogy to the human sound localization system, eliminating the need of having information from three spatially diverse Base Stations (BSs). This is inspired by the perfect human 3D sound localization with two ears. A field study is carried out in a dense urban city to verify the accuracy of the proposed technique, with more than 20 thousand measurement samples collected. The achieved positioning accuracy is meeting the latest Federal Communications Commission (FCC) requirements in the planner dimension.

In this article, a retrial queueing model will be considered with persevering customers for wireless cellular networks which can be frequently applied in the Fractional Guard Channel (FGC) policies, including Limited FGC (LFGC), Uniform FGC (UFGC), Limited Average FGC (LAFGC) and Quasi Uniform FGC (QUFGC). In this model, the examination on the retrial phenomena permits the analyses of important effectiveness measures pertained to the standard of services undergone by users with the probability that a fresh call first arrives the system and find all busy channels at the time, the probability that a fresh call arrives the system from the orbit and find all busy channels at the time and the probability that a handover call arrives the system and find all busy channels at the time. Comparison between four types of the FGC policy can befound to evaluate the performance of the system.
Proof-of-Reputation: An Alternative Consensus Mechanism for Blockchain Systems
Authors: Aluko Oladotun , Kolonin Anton
Published: August 2021

Blockchains combine other technologies, such as cryptography, networking, and incentive mechanisms, to enable the creation, validation, and recording of transactions between participating nodes. A consensus algorithm is used in a blockchain system to determine the shared state among distributed nodes. An important component underlying any blockchain-based system is its consensus mechanism, which principally determines the performance and security of the overall system. As the nature of peer-topeer(P2P) networks is open and dynamic, the security risk within that environment is greatly increased mostly because nodes can join and leave the network at will. Thus, it is important to have a system that can check against malicious behaviour. In this work, we propose a reputation-based consensus mechanism for blockchain-based systems, Proof-of-Reputation(PoR) where the nodes with the highest reputation values eventually become part of a consensus group that determines the state of the blockchain.
