Waste or resource? Investigating the interplay of structural d waste managers’ household food waste interventions
Authors: Landells Esther , Karunasena Gamithri G. , Oakden Samuel , Naweed Anjum
Published: July 2024

Globally, food waste is a significant environmental, economic and social issue. Food waste in landfill creates the potent greenhouse gas, methane, contributing to climate change, with its management predominantly falling to local governments. Despite efforts by many countries, and extensive infrastructure and market development funding, food waste continues to be landfilled, with apparently similar councils taking diverse approaches. Using a mixed methods study design, data was firstly collected from a National online survey of Australian council-based waste management staff (n = 183), with descriptive and factor analysis of the survey data revealing a strong sense of structural empowerment (PCA.75 to.90) and a preference for sourcing information from networks (48%). These results informed a series of semi-structured interviews (n = 43) which, after thematic analysis, provided rich insights into the attitudinal and situational interpretations council-based waste managers bring to decisions around household food waste management. Framed by four pillars of Structural Empowerment, the findings suggest that waste manager’s attitude is equally as important as support, resources, and knowledge and that, despite mandates and targets, individual motivational factors and organisational paradigms determined decision-making. Identified barriers included perceived capacity constraints, inadequate focus on actionable interventions, and fragmented, uninspiring, planning. This article provides important insights around 1) leveraging networks for knowledge dissemination, 2) fostering capacity-building initiatives, and 3) advocating for sustained engagement with food waste diversion within councils. This underscores the need for additional research into evolving council typologies and effectively engaging key stakeholders to achieve food waste diversion targets and address climate change impacts.
Exploring and addressing the sexual and reproductive health and other related rights of transgender women in Bangladesh: A mixed methods protocol under the policy analysis framework

Published: July 2024

Introduction

Transgender women (hijra) in Bangladesh are declared as a separate gender category by the Government. However, research revealed that they experience transphobia, which could potentially affect their physical and mental health outcomes, and their access to SRHR-related care. This warrants an exploration of their SRHR-related rights issues, particularly using a community-engaged approach. Moreover, it is crucial to operationalize these findings into actionable policies and practice. This study aims to explore and address the SRHR and other rights-related challenges experienced by hijra under the framework of policy analysis.

Methods

The study population will include hijra in four selected service centers in Dhaka, Bangladesh. In the first phase, evidence will be generated through desk review and mixed methods research. The desk review will consist of reading and analyzing literature to understand the difference between policy and reality. For the quantitative component, a first-come-first-serve sampling approach will be used on a total sample size of 296. This will be complemented by the qualitative component, which will entail in-depth interviews, focus groups and key informant interviews. Moreover, life case histories will be conducted for particularly compelling cases. These findings will be collectively analyzed through the policy analysis framework, to analyze the differences between the policy and reality, which will ultimately generate a lay summary for stakeholders. Univariate and multivariate analysis will be used for the quantitative component whereas thematic analysis will be used for the qualitative component. In the second phase, the findings from the lay summary will be shared with stakeholders and hijra community members through a series of discussions.

Discussion

There are a few limitations of the study. In particular, this study consists of various activities which may require substantial time and effort to complete. Additionally, this study merely goes up to the policy recommendation formulation stage, as opposed to formulating an intervention design. Moreover, the findings will be disseminated through various platforms, including dissemination seminars, scientific articles and the study report.
Perceived competences, attitudes, and training needs in conflict management among a cohort of Italian physiotherapists: A cross-sectional survey study
Authors: Battista Simone , De Lucia Annalisa , Testa Marco , Donisi Valeria
Published: July 2024

Conflict management is rarely explored among physiotherapists though they often work in teams. Hence, this study explored attitudes, perceived competencies, beliefs, training experiences, and needs in conflict management among Italian physiotherapists. We conducted a cross-sectional online survey study between June and September 2023 among Italian physiotherapists. The survey instrument comprised four sections. Section 1: Socio-Demographic and Professional Data: Explored participant profiles and conflict frequency. Section 2: Attitudes and Competences: assess conflict-related behaviours and management styles (Likert Scale). Section 3: Training Experiences and Needs: Evaluated training importance and conflict-related issues with other professionals (Likert Scale). Section 4: Beliefs About Factors: Participants rated (0–10) factors influencing conflict management and its impact on care and well-being. Descriptive analyses were performed, presenting continuous data as mean (SD) and categorical data as frequencies/percentages. Likert scale responses were dichotomised (agreement/disagreement), and consensus was defined as ≥70% agreement. Median, quartiles, and box-and-whisker plots depicted responses were used for 0-to-10 scales. Physiotherapists (n = 203; mean age: 39±10.40) generally leaned towards a constructive communication style, characterised by compromise and collaboration, viewing conflict management as an opportunity to grow. There was a disparity between their exhibited behaviours and self-assessment of appropriateness in conflict resolution. Only 27.6% considered their conflict resolution skills as satisfactory. However, 85.7% acknowledged the significance of being trained in conflict management. Challenges were evident in conflicts within interprofessional relationships and communication with superiors. Both personal and organisational factors were identified as influencing conflict management, with participants recognising the detrimental impact of conflicts on their well-being and patient care. This study highlighted educational gaps in conflict management among Italian physiotherapists, showing areas of improvement in their training. Our results suggested that physiotherapists might need additional training in conflict management to enhance workplace well-being and the quality of care provided.
Heterogeneous and short-term effects of a changing climate on farmers’ labor allocation: An empirical analysis of China
Authors: Zheng Wolin , Chen Xiaozhi , Xu Weiqi , Wu Zhidong
Published: July 2024

There is growing interest in the impact of climate change on agricultural labor supply in China, rigorous empirical evidence for this issue is insufficient. This potentially important channel through which climate change may affect agricultural labor supply has not received attention. Using a panel survey data of 100 administrative villages and 2977 farmers in China, we find that temperature and precipitation do affect farmers’ labor allocation, 1°C increase from the current average temperature will reduce agricultural labor supply by 0.252%, and 1mm increase from the current average rainfall will reduce agricultural labor supply by 0.001%. Climate change also leads to the decline of net agricultural income, which creates distorted incentives for households to over-supply labor to non-agriculture. Moreover, farmers with relatively lower risk tolerance preferred to reduce the current supply of agricultural labor when net agricultural income is projected to decrease under climate change scenarios.

Authors: Zhao Dan-Jie , Li Xia , Lin Hai-Xia , Zheng Hong , Zhou Di , Tang Peng
Published: July 2024

Objective

To evaluate the efficacy and safety of upadacitinib in the treatment of moderate-to-severe atopic dermatitis (AD), and provide reference for rational clinical medication.

Methods

PubMed, Medline, Embase, Web of Science, Clinical Trials Website, and Cochrane Library databases were searched from the time of establishment until January 6, 2024, to compile a list of all randomized controlled trials (RCTs) including upadacitinib in the treatment of moderate-to-severe AD. The quality of the included studies was evaluated using the Cochrane Systematic Review. Review Manager 5.3 software was utilized for statistical analysis of outcome measures.

Results

A total of five studies were included in the meta-analysis. The results revealed that the 15 mg and 30 mg upadacitinib significantly improved Eczema Area and Severity Index (EASI) 75% {[Odds Ratio (OR) = 8.58, 95% confidence interval (CI) (5.84–12.60), P < 0.00001] [OR = 15.62, 95% CI (10.89–22.42), P < 0.00001]}, Numerical Rating Scale (NRS) ≥ 4 {[OR = 7.13, 95% CI (5.63–9.01), P < 0.00001] [OR = 11.30, 95% CI (8.93–14.31), P < 0.00001]}, and Investigator’s Global Assessment (IGA) 0/1 {[OR = 8.63, 95% CI (6.60–11.27), P < 0.00001] [OR = 16.04, 95% CI (12.26–20.99), P < 0.00001]} compared to placebo. In terms of safety, although 15 mg and 30 mg upadacitinib significantly increased the overall adverse events rate compared to placebo {[OR = 1.31, 95% CI (1.09–1.58), P = 0.004] [OR = 1.85, 95% CI (1.54–2.21), P < 0.00001]}, there was no significant difference in the serious adverse events rate {[OR = 0.73, 95% CI (0.41–1.29), P = 0.28] [OR = 0.69, 95% CI (0.39–1.23), P = 0.21]} and withdrawal rate due to adverse events {[OR = 0.66, 95% CI (0.39–1.11), P = 0.12] [OR = 0.85, 95% CI (0.52–1.38), P = 0.50]} compared to placebo.

Conclusion

This meta-analysis preliminarily suggests that upadacitinib is effective and safe for usage in the treatment of moderate-to-severe AD. Additionally, upadacitinib can instantly relieve itchiness and effectively reduce symptoms and signs, with its 30-mg dose being more effective than the 15-mg dose.
Budget impact analysis of durvalumab consolidation therapy vs no consolidation therapy after chemoradiotherapy in stage III non–small cell lung cancer in the context of the Chilean health care system
Authors: Armijo Nicolás , Salas Constanza , Espinoza Nazareth , Espinoza Manuel , Balmaceda Carlos
Published: July 2024

Background

Durvalumab, used as consolidation immunotherapy, has shown to improve survival in patients with stage III non-small cell lung cancer who respond to chemoradiotherapy, based on the most recent follow-up of PACIFIC. The Chilean healthcare system provides access to certain immunotherapies for this condition. The present study sought to estimate the budget impact of durvalumab versus standard of care in the context of the Chilean healthcare system.

Research design and methods

A partitioned survival model was adapted to compare two strategies: durvalumab as consolidation therapy and standard of care for treating stage III NSCLC. The number of patients eligible for treatment was estimated using published incidence data and modeled for a 5-year time horizon. Model inputs were based on published literature, and the duration of treatment was estimated using survival curves obtained from PACIFIC. Costs were estimated in Chilean pesos (CLP) and converted to USD dollars using an exchange rate of USD 1  =  CLP 827. Scenario analyses were performed to assess different subsequent therapy splits, variations in the target population and dosage of durvalumab.

Results

Durvalumab uptake projected total costs ranging from USD 1.27 in Year 1 to 8.5 million in Year 5 from the public perspective. From the private perspective, the budget impact for the first year is USD 1.3 million to USD 3 million for 2028. This difference relies mostly on the lower number of patients treated. Both perspectives anticipated cost savings over the time horizon through reduced monitoring, adverse events, and end-of-life expenses.

Conclusions

This study demonstrates that the inclusion of Durvalumab for NSCLC in Chile represents an investment in the Chilean health system. The incremental costs align with clinical benefits and potential savings in healthcare resource utilization. However, a comprehensive cost-effectiveness analysis is needed to evaluate its economic value thoroughly.
Management of chronic non-cancer pain by primary care physicians: A qualitative study
Authors: Rufener Léa , Akre Christina , Rodondi Pierre-Yves , Dubois Julie
Published: July 2024

Chronic non-cancer pain is a highly prevalent health issue with personal and societal consequences. Patients suffering from chronic non-cancer pain are mainly cared for by primary care physicians, but research shows that the latter perceive treating chronic pain as difficult. This qualitative descriptive study aimed to explore how primary care physicians in Switzerland manage patients with chronic non-cancer pain and what factors influence patient management. Data were collected through semi-structured interviews amongst primary care physicians in the German speaking part of Switzerland. A thematic analysis of the interviews allowed to identify four main themes: Investigation of chronic pain; patient-provider relationship; patient characteristics, and medical recommendations. These themes were closely interconnected and influenced each other. Physicians not only enquired about the origin of pain but also about the patients’ beliefs and expectations towards it. They stressed the role of communication in fostering a good patient-physician relationship and to help patients cope with their pain. In addition to purely medical considerations, the psychological, social and economic situation of their patients and their possible impacts on the management of chronic non-cancer pain played a crucial role when recommending a treatment. This study highlighted the complexity of chronic pain management, which entails that primary care physicians need to figure out a unique strategy for each patient. By integrating patients’ values and beliefs, as well as socioeconomic aspects, primary care physicians are in a position to take the lead in chronic non-cancer pain management. However, considering the burden of this disease, more continuous medical education on chronic pain is needed for primary care physicians, especially to better take into account the social determinants of pain.

Published: July 2024

The ice phenomena are an inherent component of rivers in temperate, continental, and polar climate zones. Evident progress in global warming leads to a decrease in snow cover on land and ice phenomena in water bodies, disrupting the stability of the hydrological cycle and aquatic ecosystems. Although common observations indicate the disappearance of ice phenomena in rivers over recent decades, detailed quantitative research is lacking in many regions, especially in the temperate zone. In this paper, ice phenomena were analyzed on the rivers of southern Poland, located in the upland and mountain areas of the country, as no such studies have been conducted so far. The temporal changes in the annual number of days with ice (NDI) phenomena were studied in locations where ice phenomena were observed every year for at least 30 years between 1951 and 2021. Using straightforward but commonly accepted procedures, such as the Mann-Kendall test, statistically significant decreasing trends in the annual NDI were revealed for the majority of gauging stations. The Theil-Sen (TS) slope mean values were -1.66 (ranging from -3.72 to -0.56), -1.41 (from -3.22 to -0.29), and -1.33 (from -2.85 to -0.29) for the datasets representing the periods 1992–2020, 1987–2020, and 1982–2020, respectively. The results for the annual NDI were additionally presented within the context of meteorological characteristics such as annual and winter (Nov-Apr) air temperature, precipitation, and water temperature. Correlation and regression analyses revealed that the main factor triggering the decrease in NDI is the increase in the average winter air temperature. An increase in temperature by 1°C results in a decrease in NDI by up to twenty days. If these negative trends continue, ice phenomena may disappear completely from southern Polish rivers within few decades.

Authors: Usui Miki , Uchida Katsunori , Hayasaki Aoi , Kishiwada Masashi , Mizuno Shugo , Watanabe Masatoshi
Published: July 2024

Purpose

Several reports have shown the importance of margins in pancreatoduodenectomy (PD) specimens; however, whether anterior surfaces are included as margins varies among reports. In this study, we aimed to examine the impact of the anterior surface on disease-free survival (DFS) and overall survival (OS).

Method

In total, 98 patients who underwent PD after chemoradiotherapy for pancreatic ductal adenocarcinoma at Mie University Hospital between January 1, 2012, and December 31, 2019, were included. We investigated the prognostic impact of the distance from the anterior surface to tumor cells on DFS and OS using a log-rank test. Multivariate analysis was performed using Cox proportional hazards analysis.

Results

A significant difference in DFS and OS was observed up to a distance of 5 mm from the anterior surface of tumor cells. The multivariate analysis revealed that the distance from the anterior surface to tumor cells (≤5 mm) was an independent poor prognostic factor for DFS and OS.

Conclusion

In patients with PD treated with neoadjuvant therapy, the distance from the anterior surface to tumor cells is an important assessment and should be included in the pathology report.

Published: July 2024

The objective of this research was to examine the Love-Hate and Identification Relationship of Individuals Participating in Euroleague Match for Recreational Purposes. The study was conducted using a relational survey methodology. The study’s population comprises persons who watching recreational purpose part in the Euroleague match held in Istanbul in 2023–2024 season, while the sample consists of 178 voluntary participants selected through convenience sampling. The participants completed the Fan Love-Hate Scale and Fan Identification Scale, in addition to being asked about their gender, marital status, age, educational status, and frequency of attending football matches per week. The data collected from the personal information form and scales was entered into the IBM SPSS 24.0 software package for analysis. Statistical analyses were conducted using the Independent Sample T test and One-way Anova methods. The LSD test was employed to ascertain the dissimilarity between the groups. The Pearson correlation analysis was utilized to ascertain the association between the variables of love-hate and identity. In summary, it is evident that demographic factors, including gender and age, significantly influence fan perceptions and sports identification. In contrast, there is no substantial correlation observed between attributes such as level of education achieved and the frequency of engaging in sports activities, and the aforementioned outcomes. The significant associations identified between the Fan Love-Hate Scale and the Sports Fan Identification Scale underscore the complex relationship between fans’ emotional experiences and their connection to sports. Further investigations could be conducted to go deeper into the underlying causes that contribute to these relationships and inequalities, so resulting in a more thorough understanding of fan psychology.

Authors: Rahman Norlaila Abd , Ariaratnam Suthahar , Hashim Nurul Azreen , Azhar Zahir Izuan
Published: July 2024

Background

Managing chronic pain was not only a major challenge but also a source of significant disability associated with mental illness. Studies on generalized anxiety disorder (GAD) in chronic pain population was rather limited. This study was aimed to determine the prevalence of GAD and its associated factors among patients attending a pain clinic at a general hospital.

Methods

This cross-sectional study recruited 201 patients. The Hospital Anxiety Depression Scale (HADS) was used to determine anxiety level. Subsequently, patients who had scored 8 and above on the HADS were interviewed using Mini International Neuropsychiatric Interview (M.I.N.I) to ascertain the diagnosis of GAD. Whilst the Numerical Rating Scale (NRS) assessed pain severity. Multiple logistic regression analysis was used to determine factors associated with GAD.

Results

Among those patients with chronic pain, the prevalence of GAD was 18.9%. Gender (AOR:7.94; 95% CI:2.34, 26.93), duration of the pain (AOR:1.30; 95% CI:1.03,1.63) and pain severity (AOR:18.75; CI:1.23,285.13) were significant factors associated with GAD.

Conclusion

GAD is a prevalent condition among chronic pain patients.

Amidst this context, authors like Homa challenge the Aryan race as the foundation of Iranian national identity, striving to carve out a diasporic space within Iranian–Canadian literature that embraces Iran’s marginalized ethnicities, with a particular focus on Iranian–Kurdish identity.
Exile, work-related emotions and trauma among Burundian journalists in Belgium
Authors: Paviotti Antea , Broustau Nadège
Published: July 2024

In 2015, many journalists left Burundi following the outbreak of violence caused by President Nkurunziza’s candidacy for a third presidential term. From abroad, several managed to continue their journalistic activities through social media. In this article, we present the findings of a study conducted among fifteen Burundian exiled journalists in Belgium supported by the association Ensemble-Groupe d’Aide aux Journalistes Exilés (En-GAJE). We observe how journalists understand and manage the emotions provoked by exposure to social media content in exile, and we analyse their knowledge of and attitude towards post-traumatic stress disorder (PTSD) and secondary traumatic stress (STS). Our study highlights that while emotions are acknowledged by Burundian exiled journalists, emotional detachment remains a professional principle of reference for them; avoiding inactivity results to be the main coping strategy used to deal with work-related emotions and possible trauma, and this allows them to maintain their journalistic identity and authority on social media.

New media and the Language Charter: Protecting regional or minority languages in the digital age
Authors: Láncos Petra Lea
Published: July 2024

The twenty-first century saw the rapid rise of new media, increasing its share within the media mix and becoming a crucial platform for democratic debate and cultural consumption. Meanwhile, provisions related to the media in the European Charter for Regional or Minority languages merely refer to traditional forms of media. This article tries to answer the question whether the Charter with its unchanged provisions can continue to fulfil its function of protecting endangered languages, integrating the different forms of new media for the fulfilment member states’ obligations. Based on an analysis of the most recent monitoring reports of the Charter’s Committee of Experts, this research arrives at the conclusion that the Charter is indeed fit for the digital age, with both traditional and new media coming to play an important role in protecting and promoting minority and regional languages.

Published: July 2024

El análisis de las trayectorias de socialización es especialmente relevante para conocer los agentes sociales que influyen en la formación de actitudes, creencias y expectativas de corresponsabilidad con el trabajo doméstico. Este artículo examina y reconstruye las trayectorias de socialización de los varones con el trabajo doméstico desde su adolescencia hasta la convivencia con la pareja y la llegada de hijos e hijas a la familia. A partir del análisis de entrevistas semiestructuradas se han reconstruido tres tipos de trayectorias en las cuales se han podido observar la influencia socializadora de cuatro agentes sociales: la familia de origen, el grupo de amistad, el grupo de trabajo y la pareja. Los resultados confirman que la familia de origen y la pareja son los agentes que ejercen mayor influencia en la socialización de los varones con el trabajo doméstico. Se hallaron diferencias en la socialización familiar según la edad de los entrevistados, siendo las familias de las generaciones de varones más jóvenes las que delegaban en los hijos mayor número de responsabilidades con el trabajo doméstico. Asimismo, se observó cómo la influencia de la posición socioeconómica de la mujer condicionaba que la socialización conyugal lograse modificar la división del trabajo doméstico. Por último, se apreció en las tres trayectorias una tradicionalización en el reparto del trabajo doméstico con la llegada de los hijos e hijas a la familia.

Published: July 2024

Background and Aim:Hepatitis E virus (HEV) poses a global public health concern. HEV has a single serotype and 8 genotypes. There is inadequate knowledge about risk factors and zoonotic transmission pathways of hepatitis E virus in Mongolia, although the prevalence of HEV is, on average, 12% among the Mongolian population. This study aimed to estimate the prevalence and risk factors of HEV G8 infection in Bayankhongor province, Mongolia.

Materials and Methods: Human serum samples (309) were collected in Bogd, Bayangovi, and Bayanlig districts of Bayankhongor province, Mongolia, with a control group consisting of non-camel herders. An in-house indirect enzyme-linked immunosorbent assay kit was used to detect anti-HEV IgG. The interviewer-administered questionnaire was used to gather the data. The assessment factors included age, sex, and occupation for the respondents. Univariate analyses were conducted using the Statistical Package for the Social Sciences version 26. The same population was tested for hepatitis B and C viruses (HBVs and HCVs) using rapid tests.

Results: Of 309 samples, 41 (13.3%) tested positive for anti-HEV immunoglobulin G antibodies, 23 (7.4%) for HBV and 11 (3.6%) for HCV. HEV seropositivity was linked with water supply, khoormog consumption, and co-infection with HBV and HCV.

Conclusion: HEV prevalence among Bayankhongor residents underscores potential transmission routes related to water supply and khoormog consumption, emphasizing the need for sequencing from human positive sera of HEV and preventive measures. We did not conduct the genotyping of positive human samples.

Keywords: Bactrian camel herder, genotype 8, hepatitis E virus, indirect enzyme-linked immunosorbent assay, seroprevalence.

Published: July 2024

O projeto de edifícios com vários pavimentos com estruturas de aço não é um procedimento usual no Brasil. Credita- se este fato, em parte, à preocupação dos projetistas com o comportamento destas estruturas, quando em situação de incêndio. Neste artigo são realizados alguns experimentos numéricos, em ambiente MATLAB, com o objetivo de avaliar a eficiência do uso de materiais de proteção térmica sobre o aquecimento de perfis de aço. É feita a comparação entre a resistência ao fogo de um perfil de aço com e sem proteção. Compara-se também o uso de diferentes materiais de proteção (argamassas) e o efeito da espessura da proteção no aumento do tempo de resistência ao fogo. Nos experimentos numéricos realizados, a aplicação da proteção térmica nos perfis de aço prolongou o tempo para atingir a temperatura crítica de 11,8 minutos (sem proteção) para valores entre 50 e 127 minutos, variando este tempo conforme o material e a espessura da proteção utilizada.
Assessment of the Effect of Predictive Maintenance on the System Reliability
Authors: Francisco Alexandre Santos , Cardoso Lacerda Marcos Vinícius , Duncan Rangel Luis Alberto
Published: July 2024

In this work, we assess the effect of predictive maintenance on the reliability of repairable systems. In reparable systems, the reliability assessment considering corrective and preventive maintenance is well defined, but not considering predictive one. The effect of predictive maintenance is taken into account through a finite probability that the system is found in degraded condition. If the predictive maintenance evidences the degradation, then the repair is carried out. All the repairs are considered perfects, which means that the system is restored to an as-good-as-new condition each time the repair is carried out. The measure of system reliability under predictive maintenance is found to be between that of a maintenance-free strategy and preventive maintenance. The effect on the system reliability depends on the value of the probability that the system is found in degraded condition. We propose an expression for the reliability that is convenient when values of such probability are less than 15%. By using the proposed expression, one can estimate how much improvement in reliability any system gains by the predictive maintenance.
Complex Eigenvalues Analysis of the SN equations for deterministic coarse-mesh methods development applied in one-dimensional neutron shielding calculation
Authors: Libotte Rafael Barbosa , Alves Filho Hermes , Silva Fernando Carvalho da
Published: July 2024

When using spectral nodal methods in the solution of fixed-source problems, one of the steps involves obtaining the intranodal homogeneous solution of the neutron transport equations in the discrete ordinates formulation (SN), where an eigenvalue problem is solved. Up until now, this process involved the emergence of N (even order for Gauss-Legendre quadrature) real and symmetric eigenvalues. However, in some cases, complex conjugates may appear in this step. Thus, we present a significant innovation in this type of computational modelling, by using the Euler's Formula to manipulate the local analytical solution and achieve a possible application of coarse-mesh methods in these cases. In order to showcase this technique, we use the spectral deterministic method to solve a model-problem with different sets of Gaussian quadrature, which came to compute hundreds of complex eigenvalues in its analytical solution, where a good precision was achieved when comparing the obtained numerical results with the reference.

Published: July 2024

Nickel-based alloys are widely used in industry due to their remarkable corrosion resistance. Currently, most of these alloys are processed with crystalline structure. However, amorphous metal alloys commonly demonstrate greater corrosion resistance compared to their crystalline counterparts. In this study, the Ni62Nb38, Ni59.24Nb37.76B3.00, and Ni58.1Nb38.9B3.0 (atom percent) alloys with crystalline and amorphous structure were investigated. Traditional X-ray diffraction (XRD) and differential scanning calorimetry (DSC) techniques were used to characterize the alloys. Electrochemical tests were conducted to evaluate the corrosion resistance at different temperatures. Data obtained by electrochemical impedance spectroscopy and polarization curves revealed the superiority of amorphous alloys in relation to crystalline ones, for the same chemical composition. The polarization resistance of the amorphous alloys was up to 20 times greater than that of its crystalline counterparts. Both structures showed a reduction in corrosion resistance with increasing temperature. In amorphous alloys, the presence of boron made the samples more resistant to corrosion at both temperatures. Furthermore, a higher percentage of niobium among the ternary compositions also improved the corrosion properties. In crystalline alloys, the presence of boron resulted in samples that were less resistant to corrosion at a temperature of 25 °C. However, this element provided greater resistance to ternary alloys at a temperature of 45 °C. Using electrochemical techniques, it was possible to demonstrate the superior corrosion resistance of amorphous alloys compared to its crystalline counterparts.

Este estudo objetivou analisar o Horário de Trabalho Pedagógico Coletivo (HTPC) como momento de formação continuada na ótica de professores de Educação Física. Desenvolvido na abordagem qualitativa, teve como locus de produção de dados o HTPC ocorrido na rede municipal de ensino de uma cidade do interior do Estado de São Paulo, Brasil. Como instrumentos de coleta de dados foram utilizados a observação participante com registros em diários de campo e a entrevista semiestruturada. A análise do material foi feita à luz da análise de conteúdo. Os resultados expressam que o HTPC foi reconhecido como espaço e tempo para a formação continuada dos professores, segundo as situações em que ocorreram trocas de experiências sobre como preceder com o planejamento e à prática pedagógica no trato pedagógico com as crianças. O estudo colabora com discussões acerca de temas tangenciais aos processos formativos circunscritos a atuação de professores de Educação Física na infância.

A relação entre as crenças epistemológicas e o desempenho de estudantes do Ensino Médio em atividade investigativa de Física
Authors: Almeida Gabrielle de Oliveira , Gomes Alessandro Damásio Trani
Published: July 2024

Esse trabalho tem como objetivo buscar identificar a relação entre as concepções epistemológicas dos estudantes e o seu desempenho em uma atividade investigativa, realizada em duplas, por meio de uma simulação computacional. O desempenho dos estudantes foi avaliado segundo um conjunto de fatores: o total de experimentos realizados, a exploração do campo experimental, a percentagem de variáveis independentes pesquisadas; e a quantidade e/ou percentagem de testes válidos e conclusivos realizados. Participaram desta pesquisa quantitativa 184 alunos do primeiro ano do Ensino Médio de uma escola pública federal de Belo Horizonte. Os resultados sugerem que, no geral, alunos que apresentam crenças epistemológicas mais sofisticadas sobre a natureza da ciência tendem a apresentar estratégias mais adequadas de controle de variáveis e de experimentação. Com base nos resultados obtidos, são discutidas as implicações educacionais e propostas novas possibilidades de pesquisa na área.
Cartografias da comida: trajetos por educações em devires, marcas e afetos
Authors: Sales Tiago Amaral , Carvalho Daniela Franco
Published: July 2024

Este texto consiste em uma pesquisa cartográfica que se atenta ao que é possível aprender com os alimentos ao serem sentidos, deglutidos, digeridos e incorporados em diferentes espaços. Constrói-se, através do encontro entre corpos, subjetividades e comidas, um trajeto composto por escritas e imagens que percorrem espaços de comer, dividindo-se em quatro seções: comer em espaços escolares e universitários; comer no shopping; comer em restaurantes vegetarianos e comer em casa. A comida é pensada, assim, como possibilidade de engendrar educações pelos encontros entre devires, marcas e afetos que atravessam os corpos, na medida em que também os ensinam.

Published: July 2024

Este artigo objetiva analisar enunciados em entrevistas de professoras da Educação Infantil com vistas a compreender como a identidade docente se constitui nessa discursividade. O trabalho ancora-se teoricamente nos estudos educacionais que discutem sobre educação, professores, formação docente, Educação Infantil e na Análise do Discurso (AD) derivada do olhar pecheutiano e foucaultiano, em textos que tratam das noções de discurso, interdiscurso, arquivo e enunciado. Além dos estudos culturais sobre a definição de identidade, dentre outros autores que nos auxiliem na discussão da temática. A metodologia utilizada é de cunho qualitativo e interpretativo assentada na entrevista semiestruturada realizada com quatro professoras na geração dos dados. Como resultados, interpretamos que a identidade dessas professoras encontra-se em permanente construção, sendo inacabadas e perpassam a linguagem e histórias de vida no discurso educacional. Concluímos que os enunciados produzem efeitos de sentido identitários em meio às regularidades discursivas e histórica de sua emergência na contemporaneidade.

Authors: Silva Maia Francisco Jadson , Lopes Almeida Luzia Cristina
Published: July 2024

Resumo: Este trabalho é uma resenha crítica da obra Sociedade paliativa: a dor hoje do filósofo Byung-Chul Han, publicada no Brasil em 2021. O livro argumenta que predomina na sociedade contemporânea a algofobia, aversão à dor. A crescente intolerância ao sofrimento instaura no sujeito um estado quase absoluto de anestesia, que acaba cercando diferentes âmbitos da vida coletiva, do que se denomina de espaço público e de cidadania. Essa tentativa de livrar-se do sofrimento completamente configura a ascensão da democracia paliativa e das fake news, o triunfo da arte e da cultura subordinadas ao like das mídias sociais e a psicologia positiva que sustenta o sujeito do desempenho neoliberal.

Algophobia and the current palliative democracy
Abstract: This work is a critical review of the book The palliative society: pain today by philosopher Byung-Chul Han, published in Brazil in 2021. The book argues that algophobia, aversion to pain, predominates in contemporary society. The growing intolerance to suffering establishes in the subject an almost absolute state of anesthesia that ends up surrounding different areas of collective life, of what is called public space and citizenship. This attempt to get rid of suffering completely configures the rise of palliative democracy and fake news, the triumph of art and culture subordinated to the like of social media and the positive psychology that supports the subject of neoliberal performance.

Algofobia y democracia paliativa actual
Resumen: Este trabajo es una revisión crítica del libro Sociedad paliativa: el dolor hoy del filósofo Byung-Chul Han, publicado en Brasil en 2021. El libro argumenta que la algofobia, la aversión al dolor, predomina en la sociedad contemporánea. La creciente intolerancia al sufrimiento instaura en el sujeto un estado de anestesia casi absoluto que termina por envolver diferentes ámbitos de la vida colectiva, de lo que se denomina espacio público y ciudadanía. Este intento de acabar con el sufrimiento configura por completo el auge de la democracia paliativa y las fake news, el triunfo del arte y la cultura subordinados a las redes sociales y la psicología positiva que sustenta el sujeto de la actuación neoliberal.
