Published: January 2023

By solid-phase synthesis from elemental Cu, Ni, Sn, and S samples Cu2-deltaNiSnS4 (0≤delta≤0.2) was prepared. The parameters of their crystal lattice have been refined. The lifetimes of photogenerated current carriers in Cu2-deltaNiSnS4 were estimated for the first time by the contactless time-resolved microwave photoconductivity method. This times turned out to be tau~7 ns, which is comparable with the literature data for the times in kesterites CZTS. Herewith, in kinetics of loses of photogenerated cureent carriers is observed predominance of bimolecular recombination processes over capture processes. Keywords: Cu2-deltaNiSnS4, onequilibrium current carriers, lifetimes, kinetics.

Published: January 2023

An ellipsometric technique has been developed which makes it possible to observe changes in the composition and temperature of cadmium--mercury--tellurium layers during their growing by molecular beam epitaxy. The technique was tested for diagnostics the variations of the composition and the temperature during layer growth in the mode of constant power of the substrate heater and with its sharp change. It was found that the drop in power and a following decrease in the growth temperature were also accompanied by a monotonic decrease in the composition. In the case of a constant heater power, a slight increase in the sample temperature was observed with an almost unchanged composition of the growing layer. Keywords: ellipsometry, mercury--cadmium--telluride, in situ control, epitaxial growth, temperature.

The analysis of the shrinkage rate of powders, based on the power-law creep model of a porous body, was carried out in this paper to calculate the compaction parameters of CoSb3-based skutterudites and Fe2VAl-based Heusler alloys within field-activated sintering. It was indicated that this method, which had already been used for metal and ceramic powders, is applicable for thermoelectric powders. The values of strain rate sensitivity were obtained, and the corresponding powder compaction mechanisms have been defined. The main creep mechanism for skutterudites was found to be a dislocation climb, that later was replaced by grain boundary sliding, and the last sintering stage was associated with diffusional creep. The main creep mechanism for Heusler alloys was grain boundary sliding, later replaced by diffusional creep. Keywords: field-assisted sintering, numerical simulation, powders compaction, skutterudites, Heusler alloys, thermoelectrics.
Looking Beyond the Mother: Investigating Relationship Characteristics and Postpartum Depression Risk Factors
Authors: Jewell Jennifer S. , Brooks-Russell Ashley , Leiferman Jenn
Published: January 2023

Postpartum depression (PPD) affects a notable number of women. While many of the risk and protective factors for PPD are specific to the mother, there are also factors that are related to the partner. However, the partner is often overlooked when assessing the landscape of PPD and potential treatment programs. This study sought to expand the knowledge on partner perceptions during the perinatal period. This online, cross-sectional survey of fathers who were in relationships with mothers who had given birth within the last five years or were currently pregnant, included the topics of PPD knowledge and experience, confidence and preparedness in dealing with postpartum changes, expected changes in the relationship, stress, relationship satisfaction, and communication quality. Results of the linear regression analyses indicated significant relationships between communication quality and confidence (p = 0.021), preparedness (p = 0.005), stress (p < 0.001), and postpartum relationship changes (p < 0.001). Relationship satisfaction was also significantly related to confidence (p < 0.001), preparedness (p < 0.001), stress (p < 0.001), and postpartum relationship changes (p < 0.001). These findings indicate that relationship characteristics may be a vital component in factors related to PPD. The increasing significance and strength of communication quality as a predictor of variables such as confidence in helping the mother cope with mental health struggles indicates that with increased communication skills and quality, couples can reduce their joint risk factors for PPD. Similar evidence was found for relationship satisfaction. This study supports the theory that partners are a vital component in the family system, and they have to ability to positively influence postpartum maternal mental health outcomes.

Published: January 2023

Cytomegalovirus (CMV) infection is the most common infection affecting kidney transplant recipients [1]. CMV may be present as asymptomatic viremia or with symptoms ranging from mild to significant tissue-invasive disease [1-3]. Optimal kidney graft function and survival requires that transplant care teams carefully assess individual patient risk of CMV [2, 3]. Appropriate patient surveillance and prophylaxis are essential to ensure the best long-term kidney transplant results. Effective treatment of CMV disease requires a high degree of suspicion and appropriate diagnostic tests. The choice of antiviral medication and duration of treatment are important considerations to ensure optimal patient outcomes and kidney graft function and survival.

Voice Assistants’ Responses to Questions About the COVID-19 Vaccine: National Cross-sectional Study
Authors: Sossenheimer Philip , Hong Grace , Devon-Sand Anna , Lin Steven
Published: January 2023

Background

Artificial intelligence-powered voice assistants (VAs), such as Apple Siri, Google Assistant, and Amazon Alexa, interact with users in natural language and are capable of responding to simple commands, searching the internet, and answering questions. Despite being an increasingly popular way for the public to access health information, VAs could be a source of ambiguous or potentially biased information.

Objective

In response to the ongoing prevalence of vaccine misinformation and disinformation, this study aims to evaluate how smartphone VAs respond to information- and recommendation-seeking inquiries regarding the COVID-19 vaccine.

Methods

A national cross-sectional survey of English-speaking adults who owned a smartphone with a VA installed was conducted online from April 22 to 28, 2021. The primary outcomes were the VAs’ responses to 2 questions: “Should I get the COVID vaccine?” and “Is the COVID vaccine safe?” Directed content analysis was used to assign a negative, neutral, or positive connotation to each response and website title provided by the VAs. Statistical significance was assessed using the t test (parametric) or Mann-Whitney U (nonparametric) test for continuous variables and the chi-square or Fisher exact test for categorical variables.

Results

Of the 466 survey respondents included in the final analysis, 404 (86.7%) used Apple Siri, 53 (11.4%) used Google Assistant, and 9 (1.9%) used Amazon Alexa. In response to the question “Is the COVID vaccine safe?” 419 (89.9%) users received a direct response, of which 408 (97.3%) had a positive connotation encouraging users to get vaccinated. Of the websites presented, only 5.3% (11/207) had a positive connotation and 94.7% (196/207) had a neutral connotation. In response to the question “Should I get the COVID vaccine?” 93.1% (434/466) of users received a list of websites, of which 91.5% (1155/1262) had a neutral connotation. For both COVID-19 vaccine–related questions, there was no association between the connotation of a response and the age, gender, zip code, race or ethnicity, and education level of the respondent.

Conclusions

Our study found that VAs were much more likely to respond directly with positive connotations to the question “Is the COVID vaccine safe?” but not respond directly and provide a list of websites with neutral connotations to the question “Should I get the COVID vaccine?” To our knowledge, this is the first study to evaluate how VAs respond to both information- and recommendation-seeking inquiries regarding the COVID-19 vaccine. These findings add to our growing understanding of both the opportunities and pitfalls of VAs in supporting public health information dissemination.

Published: January 2023

Background

Evidence-based point-of-care information (POCI) tools can facilitate patient safety and care by helping clinicians to answer disease state and drug information questions in less time and with less effort. However, these tools may also be visually challenging to navigate or lack the comprehensiveness needed to sufficiently address a medical issue.

Objective

This study aimed to collect clinicians’ feedback and directly observe their use of the combined POCI tool DynaMed and Micromedex with Watson, now known as DynaMedex. EBSCO partnered with IBM Watson Health, now known as Merative, to develop the combined tool as a resource for clinicians. We aimed to identify areas for refinement based on participant feedback and examine participant perceptions to inform further development.

Methods

Participants (N=43) within varying clinical roles and specialties were recruited from Brigham and Women’s Hospital and Massachusetts General Hospital in Boston, Massachusetts, United States, between August 10, 2021, and December 16, 2021, to take part in usability sessions aimed at evaluating the efficiency and effectiveness of, as well as satisfaction with, the DynaMed and Micromedex with Watson tool. Usability testing methods, including think aloud and observations of user behavior, were used to identify challenges regarding the combined tool. Data collection included measurements of time on task; task ease; satisfaction with the answer; posttest feedback on likes, dislikes, and perceived reliability of the tool; and interest in recommending the tool to a colleague.

Results

On a 7-point Likert scale, pharmacists rated ease (mean 5.98, SD 1.38) and satisfaction (mean 6.31, SD 1.34) with the combined POCI tool higher than the physicians, nurse practitioner, and physician’s assistants (ease: mean 5.57, SD 1.64, and satisfaction: mean 5.82, SD 1.60). Pharmacists spent longer (mean 2 minutes, 26 seconds, SD 1 minute, 41 seconds) on average finding an answer to their question than the physicians, nurse practitioner, and physician’s assistants (mean 1 minute, 40 seconds, SD 1 minute, 23 seconds).

Conclusions

Overall, the tool performed well, but this usability evaluation identified multiple opportunities for improvement that would help inexperienced users.

Authors: Ray Anne E , Mun Eun-Young , Lewis Melissa A , Litt Dana M , Stapleton Jerod L , Tan Lin , Buller David B , Zhou Zhengyang , Bush Heather M , Himelhoch Seth
Published: January 2023

Background

Underage drinking and related risky sexual behavior (RSB) are major public health concerns on United States college campuses. Although technology-delivered personalized feedback interventions (PFIs) are considered a best practice for individual-level campus alcohol prevention, there is room for improving the effectiveness of this approach with regard to alcohol-related RSB.

Objective

The aims of this study are to (1) evaluate the impact of a brief PFI that integrates content on alcohol use and RSB and is adapted to include a novel cross-tailored dynamic feedback (CDF) component for at-risk first-year college students and (2) identify implementation factors critical to the CDF’s success to facilitate future scale-up in campus settings.

Methods

This study uses a hybrid type 1 effectiveness-implementation design and will be conducted in 3 phases. Phase 1 is a stakeholder-engaged PFI+CDF adaptation guided by focus groups and usability testing. In phase 2, 600 first-year college students who drink and are sexually active will be recruited from 2 sites (n=300 per site) to participate in a 4-group randomized controlled trial to examine the effectiveness of PFI+CDF in reducing alcohol-related RSB. Eligible participants will complete a baseline survey during the first week of the semester and follow-up surveys at 1, 2, 3, 6, and 13 months post baseline. Phase 3 is a qualitative evaluation with stakeholders to better understand relevant implementation factors.

Results

Recruitment and enrollment for phase 1 began in January 2022. Recruitment for phases 2 and 3 is planned for the summer of 2023 and 2024, respectively. Upon collection of data, the effectiveness of PFI+CDF will be examined, and factors critical to implementation will be evaluated.

Conclusions

This hybrid type 1 trial is designed to impact the field by testing an innovative adaptation that extends evidence-based alcohol programs to reduce alcohol-related RSB and provides insights related to implementation to bridge the gap between research and practice at the university level.

Usability Evaluation of a Knowledge Graph–Based Dementia Care Intelligent Recommender System: Mixed Methods Study (Preprint)
Authors: Leng Minmin , Sun Yue , Li Ce , Han Shuyu , Wang Zhiwen
Published: January 2023

BACKGROUND

Knowledge graph–based recommender systems offer the possibility of meeting the personalized needs of people with dementia and their caregivers. However, the usability of such a recommender system remains unknown.

OBJECTIVE

This study aimed to evaluate the usability of a knowledge graph–based dementia care intelligent recommender system (DCIRS).

METHODS

We used a convergent mixed methods design to conduct the usability evaluation, including the collection of quantitative and qualitative data. Participants were recruited through social media advertisements. After 2 weeks of DCIRS use, feedback was collected with the Computer System Usability Questionnaire and semistructured interviews. Descriptive statistics were used to describe sociodemographic characteristics and questionnaire scores. Qualitative data were analyzed systematically using inductive thematic analysis.

RESULTS

A total of 56 caregivers were recruited. Quantitative data suggested that the DCIRS was easy for caregivers to use, and the mean questionnaire score was 2.14. Qualitative data showed that caregivers generally believed that the content of the DCIRS was professional, easy to understand, and instructive, and could meet users’ personalized needs; they were willing to continue to use it. However, the DCIRS also had some shortcomings. Functions that enable interactions between professionals and caregivers and that provide caregiver support and resource recommendations might be added to improve the system’s usability.

CONCLUSIONS

The recommender system provides a solution to meet the personalized needs of people with dementia and their caregivers and has the potential to substantially improve health outcomes. The next step will be to optimize and update the recommender system based on caregivers’ suggestions and evaluate the effect of the application.

Authors: Asih Anna Maria Sri , Trapsilawati Fitri , Sopha Bertha Maya , Normasari Nur Mayke Eka
Published: January 2023

Waste management is crucial in the present day, particularly due to the increase in trash production caused by population growth. To address this issue, the government has implemented the Waste Bank Program, which aims to reduce the amount of waste stored at disposal sites. This program has had a significant impact on the management of household waste, which makes up the majority of all waste generated in Indonesia. Despite its importance, participation in the Waste Bank program is low in many communities. To address this issue, a community activity was organized in Sleman, Yogyakarta Special Region to promote and implement the Waste Bank program in one of the 44-family Neighborhood Units. The focus of this activity was the management of inorganic trash. During the six-month period from April to October 2021, the Waste Bank program had a significant increase in participation, with the percentage of community members taking part rising from 27% to 60%. As a result of these efforts, a total of 1,084 kg of inorganic trash was collected. This waste was primarily composed of paper, followed by plastic, various other materials such as iron, aluminum, and used cooking oil, and a smaller amount of glass. The report summarizes the steps taken, challenges encountered, and potential solutions implemented during the initiation of the Waste Bank program. Additionally, the community was able to save 16% of the revenue generated from the collected trash through monthly environmental fees. These findings provide valuable insight into the current state of waste generation and the community’s situation, which can inform future efforts to reduce waste.

Published: January 2023

Background

The GFR slope has been evaluated as a surrogate end point for kidney failure in meta-analyses on a broad collection of randomized controlled trials (RCTs) in CKD. These analyses evaluate how accurately a treatment effect on GFR slope predicts a treatment effect on kidney failure. We sought to determine whether severity of CKD in the patient population modifies the performance of GFR slope.

Methods

We performed Bayesian meta-regression analyses on 66 CKD RCTs to evaluate associations between effects on GFR slope (the chronic slope and the total slope over 3 years, expressed as mean differences in ml/min per 1.73 m2/yr) and those of the clinical end point (doubling of serum creatinine, GFR <15 ml/min per 1.73 m2, or kidney failure, expressed as a log-hazard ratio), where models allow interaction with variables defining disease severity. We evaluated three measures (baseline GFR in 10 ml/min per 1.73 m2, baseline urine albumin-to-creatinine ratio [UACR] per doubling in mg/g, and CKD progression rate defined as the control arm chronic slope, in ml/min per 1.73 m2/yr) and defined strong evidence for modification when 95% posterior credible intervals for interaction terms excluded zero.

Results

There was no evidence for modification by disease severity when evaluating 3-year total slope (95% credible intervals for the interaction slope: baseline GFR [−0.05 to 0.03]; baseline UACR [−0.02 to 0.04]; CKD progression rate [−0.07 to 0.02]). There was strong evidence for modification in evaluations of chronic slope (95% credible intervals: baseline GFR [0.02 to 0.11]; baseline UACR [−0.11 to −0.02]; CKD progression rate [0.01 to 0.15]).

Conclusions

These analyses indicate consistency of the performance of total slope over 3 years, which provides further evidence for its validity as a surrogate end point in RCTs representing varied CKD populations.

Authors: Santana Marcos Aurélio Alves de , Neta Neusa Barros Dantas , Pereira Gleiciane de Souza , Souza Mariana Silva
Published: January 2023

Mauritia flexuosa, known as ‘buriti’, is an excellent source of bioactive compounds with antioxidant, hypolipidaemic, sun protection, antiplatelet, antithrombotic, hypoglycaemic, antimicrobial and antitumour properties. Considering these properties, it could be used as a therapeutic for conditions that affect the mouth, such as ulcerations and erythema. Among the oral conditions, we can mention oral mucositis, which is characterised by erythema, atrophy and ulceration of the mucous membrane. Thus, this work aimed to develop a phytotherapeutic pharmaceutical formulation for oral application that contains 5% buriti oil as the active ingredient. Five formulations were developed, and one (F5) of the formulations was chosen and subjected to organoleptic and physicochemical analysis (pH, density, and high-performance liquid crhromatography - HPLC), and later to a 3-month stability study in an accelerated climactic chamber. The initially obtained gel/cream was stable according to the tests to which it was submitted. However, after storage for 3 months, it showed a markedly reduced density, indicating the loss of volatile compounds, possibly vitamins A and E. Overall, the gel/cream formulated with buriti oil displays characteristics that make it potentially suitable for the treatment of oral ulcerations such as oral mucositis.

Published: January 2023

U kapitalizmu zainteresovanih strana, kompanije teže dugoročnom stvaranju vrednosti čime je i naglašena potreba za javno-privatnim partnerstvima. Vlade diljem sveta pokazale su snažan entuzijazam prema usvajanju ovog koncepta u različitim sektorima infrastrukture usled nezadovoljstva zbog neefikasnosti javnog sektora. U interesu privatnog sektora i interesa zajednica usmerenih na dobrobit, država ima ključnu ulogu u regulisanju odnosa između partnera i održavanje jednakih uslova u poslovanju. Ona ujednačava uslove za takvo partnerstvo i omogućuje njihovo efikasno delovanje kao oblika privatizacije, širenja interesa privatnog sektora i tržišta.
Cilj rada je ukazati da su motivi za usvajanje javno privatnog partnerstva od strane vlada usmereni ka efektivnosti ovakvog oblika partnerstva kroz promovisanje brze isporuke projekata javne infrastrukture i podeljenim rizicima javnog i privatnog sektora, prilagođavajući se novom obliku kapitalizma u kome kompanije dobivaju ulogu partnera u javnim poslovima, a koji podržavaju razne institucije međunarodne zajednice. Takvu politiku sledi i vlada Srbije koja podupire napore da se nadležnosti javnih preduzeća mogu delimično ili u potpunosti preneti na privatni sektor, sledeći praksu zemalja Evropske unije u unapređenju energetske efikasnosti na svim nivoima.

U radu se najpre prezentuje uvodni teorijski i metodološki predložak katoličkog srpstva kroz istoriju. U radu je prikazano šta o svom etno-jezičkom identitetu kažu dubrovački i drugi Srbi katolici. Poseban aspekt rada čini prikaz Pokreta Srba katolika u Dubrovniku i njihov politički i nacionalni angažman od osamdesetih godina 19. veka pa do početka Prvog svetskog rata. Posebno je upečatljiva njihova nacionalna i kulturna delatnost kroz brojna kulturna, umetnička, književna i druga udruženja, zaključno sa najvišom nacionalnom kulturnom institucijom – Maticom srpskom u Dubrovniku. U radu je predstavljen i kraći pregled Srba katolika u Bosni i Hercegovini i Slavoniji, kroz prizmu kulturne, političke i nacionalne delatnosti njihovih najznačajnijih književnika, kulturnih i javnih delatnika. Najzad prikazan je proces gašenja katoličkog srpstva i njihovog pretvaranja u Hrvate, kojim je otpočeo proces političkog katoličanstva – stvaranja hrvatstva na katoličkim osnovama, što je postala doktrina Prvog hrvatskog katoličkog sastanka 1900. godine, koji je organizovan pod pokroviteljstvom pape Lava XIII, zatim nastavljen u periodu prve i druge Jugoslavije, sve do sloma zajedničke jugoslovenske države. Ovaj proces prikaz je na primeru novije i savremene istorije Dubrovnika.
Investigation of the thermal behavior of water flow within parallel tubes in a solar collector

Published: January 2023

This paper discusses the numerical simulation of the thermal behavior of steady-state water flows within parallel tubes in a plane solar collector. The CFD modeling technique, which is based on the finite volume method, has been implemented with the SIMPLE algorithm. The governing equations of the flow are those of Navier-Stokes, coupled with the energy conservation equation, and solved by using the computer software FLUENT. The profiles of water temperature are analyzed for different mass flow rates. A considerable increase in the heat transfer between the absorber wall and the tubes was observed at the low velocity of water flows. The lower mass flow rate allowed a longer residence time of fluid, and the slower mass flow yielded an increased outlet temperature.
A Semantic Framework based on Domain Knowledge for Opinion Mining of Drug Reviews
Authors: Noferesti Samira , Shamsfard Mehrnoush
Published: January 2023

Opinion mining has been attracting increasing attention in recent years. Existing approaches to opinion mining that have worked on general domains face two major challenges for polarity classification of drug reviews. Firstly, indirect opinions frequently occur in the drug domain, while the existing methods have mainly focused on direct opinions and ignored the indirect ones. Secondly, previous works are not sufficient for polarity classification of ambiguous concepts in the drug domain.

This paper proposed a semantic framework based on domain knowledge for resource construction and exploitation for indirect opinion mining of drug reviews. Accordingly, some methods were introduced, developed, and compared for building and exploiting a combined knowledge base, polarity-tagged corpus, and context-aware resources for the polarity detection of drug reviews. The test results showed that the proposed methods reached a precision of 89.18% and 80.4% in the application of the combined knowledge base and the polarity-tagged corpus for polarity detection of indirect opinions, respectively. Also, a precision of 79.93% was achieved with the use of context-aware resources constructed for the polarity detection of ambiguous concepts. Overall, the results obtained demonstrated the performance of the proposed methods compared to the existing methods.

Published: January 2023

Abstract: As a result of the pandemic, a technological paradigm shift has happened. One such field of research is the development and usage of a virtual mouse in place of a real one. Despite the fact that a remote mouse or Bluetooth mouse is popular nowadays, it requires various factors such as cost and power. There would be no such cutoff points in the proposed system, assuming signal acknowledgement. The primary breakthroughs used in this review are object recognizable proof and image management. Thus, this study proposes a cutting-edge method for dealing with mouse developments employing an ongoing camera with the help of the hand. It does not necessitate the use of any electrical device. It will use various hand gestures to direct activities such as left click and hauling. For the product's execution, Python and OpenCV will be used.

Abstract: Due to covid nearly 27 crore people were affected by this pandemic including over 5 Lakh deaths as per WHO statistics. Covid disease is considered a pandemic when it is spread all over the world. The covid disease is being spread because of the contact of infected people with others. Therefore, to detain the spread of the virus we require an effective monitoring system that monitors people in public places. This model proposes a approach for social distancing detection using deep learning to calculate the distance between people to reduce the spread of this coronavirus. The detection tool was developed to assess a video feed and show the violations. The video captured using the camera was given as input, and the open-source object detection pre-trained model known as YOLOv3 (Transfer Learning) was used for detection because from an experimental analysis, it is proved that YOLO v3 tracking methods shows reliable results with better mAP and FPS score to detect people or objects in real-time. The camera captures the video. Using this project, we can make sure that people follow the rules of socialization.
Predicting dependency level in dyadic friendship
Authors: Nurjaman Tabah Aris
Published: January 2023

This study aims to (1) investigate the dyadic friendship domain and (2) test it as a predictor of a friendship dependency level. The study was conducted in two stages: Study I and Study 2. Study I explored four friendship domains by using an indigenous psychological approach. Study 2 predicted the dyadic codependency level based on the finding of Study I by implementing an Artificial Neural Network (ANN) with a Multilayer Perceptron (MLP) model conducted in 25 experiments (5 hidden layers x 5 epochs). Data collection was carried out using five open-ended questions and one closed-ended question in Study I; and the Investment Model Scale adaptation questionnaire (13 items; α = 0.832) in Study 2. Study 1 and Study 2 were conducted at a time on 268 respondents (52 male, 216 female). The finding of Study I showed that friendship starts from: (a) the initial contact, which was based on the proximity factor (48.51%), (b) closeness, which was based on personality factors (36.19%), (c) the most frequent activities carried out together in the form of hanging out (52.61%), and (d) the reason for fear of losing a partner due to personality factors (29.48%). Study 2 revealed that friendship dependency level can be predicted by four friendship domains with an accuracy level of 58.35%, in which the initial contact and joint activity domain was of higher importance than the two others (epoch = 5000; hidden layer = 4 units). The overall findings showed that the dyadic codependency level not only can be calculated after friendships are formed and developed but also can be predicted from the initial stages of a relationship when acquaintanceship occurs.

Published: January 2023

La restricción del agua y altas temperaturas son factores limitantes que afectan el desarrollo de las plantas. En este estudio se evaluó el efecto del estrés hídrico en chile Huacle negro con tres intervalos de tensión de humedad en el suelo (10 a 20, 21 a 30 y 31 a 40 kPa) en camas de siembra con y sin acolchado de 0.9 m de ancho y 6.0 m de largo. Se utilizó un diseño bifactorial con cuatro repeticiones conformadas con 18 plantas cada una. Se evaluaron 27 variables en planta y fruto. La mayor disponibilidad de humedad en el suelo con acolchado aumentó 85% los botones florales, 89% las flores y 61% los frutos respecto al tratamiento con ma­yor estrés hídrico sin acolchado; además, presentó el mayor rendimiento de fruto seco (122.9 g), frutos más dulces (20.4%), tasa de asimilación neta (0.11 g cm2 d-1), tasa de crecimiento absoluto (2.72 g d-1) y tasa de crecimiento relativo (0.13 g g-1 d-1). La menor tensión de humedad en el suelo produjo mayor altura de planta (65.3 cm) y diámetro del tallo (11 mm). Por último, la mayor tensión de humedad en el suelo con acolchado ocasionó 30% de senescencia.

Published: January 2023

New building materials and products in construction and reconstruction, which improve the performance and efficiency characteristics of buildings, reduce material consumption, cost and labor intensity, are always relevant. A promising direction for further development of composite materials is the employment of pre-bound aggregate materials. Their production is a two-stage process, which involves at first creating an optimal aggregate mix and gluing the grains to each other and secondly filling the voids of the obtained aggregate framework with a high-workability matrix. Presented research is an experimental investigation of physical and technical properties of pre-bound aggregate composite materials. Composites with complex binders are also considered in this study. In such cases, the aggregate framework and the grouting matrix were made of binders of different nature, which are incompatible when the components are mixed ordinarily. When studying composites, a complex of physical and mechanical methods was used. Improvement of physical and mechanical properties of framework composites in comparison with composites obtained according to conventional techno- logy has been established. These advantages are identified primarily for such properties as deformability, impact strength, creep.

Neste artigo é discutida a construção das propostas de contextualização e abordagem de temas transversais na política curricular, a partir da análise de conteúdo de alguns documentos legais. A análise permitiu identificar as concepções de integração curricular difundidas pelos documentos e indicar que, apesar das recentes reformas curriculares dificultarem o desenvolvimento de aprendizagens significativas no âmbito da educação básica, a integração curricular pode contribuir para o desenvolvimento de propostas pedagógicas que melhor atendam as demandas sociais que emergem das diferentes realidades.
Jornada escolar para além dos muros da escola
Authors: Pereira da Cunha de Mendonça Salim Adriana
Published: January 2023

Exploro neste relato de experiência a proposta de Educação Integral do Centro de Ensino Professor Darcy Ribeiro, que atendia estudantes dos anos finais do ensino fundamental no contraturno, proporcionando a ampliação da jornada fora do espaço de escolarização, colocada em prática por educadores/as da rede de ensino de Petrópolis/RJ, entre 2014-2016. O Centro de Ensino era considerado núcleo-piloto da vertente Aluno em Tempo Integral do Plano Municipal de Educação Integral. Pode se constatar que o Centro foi bem sucedido em sua prática, as matriculas por oficina aumentaram gradativamente ao longo dos anos, chegando quase a dobrar de quantidade no terceiro ano de implantação do Darcy. Contudo, em 2017, com a mudança da administração municipal após as eleições no final de 2016, a nova equipe da SEMED modificou as diretrizes pedagógicas, exonerando a equipe gestora e descaracterizando a ideia do espaço como Núcleo de Educação Integral. Este relato está embasado em minha dissertação de mestrado, e ouso transparecer o encantamento que me moveu durante o período em que acompanhei a ‘equipe do Darcy’ e, juntos/as, vivemos a melhor experiência pedagógica de nossas vidas.
Educación comunitaria en contextos urbanos
Authors: Àngel Essomba Miquel
Published: January 2023

La educación comunitaria es el marco teórico y conceptual que da respuesta a los desafíos de la política educativa mundial a la hora de garantizar el derecho a la educación para todos. Cuando la educación comunitaria aterriza en los contextos urbanos, desarrolla diferentes formatos: comunidades de aprendizaje, ciudades educadoras. Una ciudad educadora es un territorio urbano con identidad propia que decide adherirse al movimiento mundial de ciudades educadoras impulsado en los años noventa a partir de una conferencia internacional que tuvo lugar en Barcelona (España). Este compromiso de adhesión significa que se pone en marcha la educación comunitaria: el conjunto de agentes sociales y educativos de la ciudad toman conciencia de su corresponsabilidad educativa, y desarrollan acciones concretas para articular redes de apoyo y dinamización educativa entre ellos. Toda esta dinámica se concreta en un eje vertebrador de la acción, denominado “Proyecto Educativo de Ciudad”. Las ciudades educadoras son una macroestrategia social de naturaleza inclusiva, por lo que todos los ciudadanos y grupos de la ciudad se ven invitados a participar activamente del proceso. En este sentido, la construcción del Proyecto Educativo de Ciudad, como eje vertebrador de la propuesta de ciudad educadora, es una buena oportunidad para activar espacios de encuentro y de trabajo entre personas de distintos orígenes culturales, sociales, religiosos o lingüísticos.

A professora é reconhecida como uma alfabetizadora bem-sucedida, sendo que a relevância metodológica de sua ação é ressaltada no estudo a partir da compreensão de como o processo de aprendizado da leitura na alfabetização pode ser concebido em uma perspectiva discursiva.
Educação Popular
Authors: Paulo Fernanda dos Santos , Madalena Costa Daianny
Published: January 2023

Neste artigo discutimos os conceitos de gestão democrática da escola e o projeto de Cidades Educadoras na perspectiva da Educação Popular, a partir de um estudo bibliográfico e do Estado do Conhecimento dos trabalhos apresentados no grupo de trabalho de Educação Popular (GT 6) da ANPED. Através da pesquisa constatou-se que Paulo Freire é uma referência na construção de políticas sociais emancipatórias conectadas às Cidades Educadoras, contribuindo para um projeto de sociedade radicalmente democrático. Concluiu-se também a necessidade da retomada de pesquisas de Programas de Pós-Graduação em Educação sobre Cidades Educadoras e Educação Popular libertadora, com o objetivo de se contrapor à concepção de Cidade Educadora sustentada pela lógica do Estado capitalista e da educação mercadológica.

Authors: Costa Araújo Carlos Wagner , Ribeiro Marcos Antonio Pinto , Agliardi Ilda Renata Silva , Célia Luciana dos Santos
Published: January 2023

O presente ensaio faz parte da pesquisa de doutorado desenvolvida por um dos/as autores/as e propõe analisar e discutir as cidades que educam em interlocução com territórios que educam. A pesquisa é bibliográfica e documental, a partir do encontro com as teorias de Paulo Freire, Theodor Adorno e Anísio Teixeira, na perspectiva da educação crítica, emancipatória, democrática, libertadora e sem privilégios. Além disso, investiga como as temáticas educação integral e educação científica dialogam com as Cidades Educadoras. Os entrelaçamentos dos temas podem corroborar políticas de educação científica nos espaços científico-culturais de cidades que são ou pretendem ser educadoras tendo a ciência como leitura de mundo.
Estudos decoloniais
Authors: Aquino dos Santos Cynara Fernanda , Moraes Corrêa Sérgio Roberto
Published: January 2023

Este artigo tem como pergunta central: quais as contribuições dos estudos decoloniais para imaginar pedagogias outras no contexto rural-ribeirinho amazônico? O texto centra-se numa reflexão de ordem epistemológica, dando ênfase aos estudos decoloniais, em diálogo com as Epistemologias do Sul. A partir de pesquisa bibliográfica e revisão da literatura sobre o assunto, foi possível identificar que os estudos decoloniais contribuem com o protagonismo científico, educacional e cultural dos movimentos sociais de populações do campo, ribeirinhos, quilombolas e povos originários. Contribuem igualmente com o compromisso epistêmico, ético, político e social na construção de outras teorias e práticas pedagógicas decoloniais que dialoguem com os modos de vida e as diferentes complexidades inerentes a esses contextos, a partir de uma postura intercultural crítica e responsável em relação aos saberes educativos e culturais das margens da Amazônia.

Published: January 2023

O artigo analisa a jornada de trabalho docente na rede estadual de ensino básico do Pará, desde os anos 1980, chamando a atenção para a ampliação do tempo de trabalho como fator de aumento da remuneração. Parte-se de uma discussão teórica sobre o tempo na reprodução do trabalho e do capital, com base no materialismo histórico, para explicar as contradições e mediações existentes entre tempo, trabalho e crescimento da jornada. É analisado também o papel do Estado na definição da jornada e dos salários, assim como seus efeitos na vida do/a professor/a. O texto foi construído a partir do levantamento de dados documentais, e os primeiros resultados obtidos revelaram um acentuado aumento da jornada de trabalho docente.
