Authors: Carbone Elena , Feraco Tommaso , Innocenti Ivan , Musicanti Monica , Volpe Paola , Meneghetti Chiara
Published: December 2024

Promoting environmental sustainability is becoming a priority for organizations. There is thus increasing interest in understanding to what extent green workplace behaviors are linked, alongside contextual determinants, to employees’ characteristics. This study investigated the relationship between green workplace behaviors, various employee characteristics, and organizational determinants. A sample of 513 employees from the energy sector was administered a survey assessing green workplace behaviors and the management of events (e.g., weak signals) which could anticipate the occurrence of incidents with harmful environmental impacts. Employees’ job-related (proneness toward behaving pro-environmentally at work) and broader individual characteristics (personality and human-nature connectedness), as well as their perceived organizational support (e.g., green climate and leadership), were also examined. The results from the structural equation models showed that green workplace behaviors were associated with employees’ proneness toward behaving pro-environmentally at work and perceived organizational support. Indirect effects from organizational support, personality, and human-nature connectedness on green workplace behaviors, mediated by employees’ proneness toward behaving pro-environmentally at work, also emerged. These findings highlight that employees’ characteristics also favor their adoption of green workplace behaviors, with important implications for developing interventions promoting environmental sustainability in organizations.

Published: December 2024

Climate change and eutrophication have significant impacts on aquatic ecosystems, with phytoplankton playing a critical role as primary producers. This study investigates the relationships between phytoplankton communities and environmental and meteorological factors in Wuliangsuhai Lake, a representative ecosystem in an arid and cold region of China. Using data from 25 sampling sites (April–September 2023), a generalized additive model (GAM) was employed to analyze water quality and laboratory measurements. The results showed a bimodal distribution of phytoplankton density, with peaks in July (5.33 × 106 cells/L) and August (14.90 × 106 cells/L). Green algae dominated in spring, while cyanobacteria became dominant in summer. GAM analysis revealed that temperature (TEMP) was the primary driver, explaining 20.7% of the deviance. When TEMP was examined together with other factors, the explanatory ability of the model was significantly enhanced, and finally, the model explained 57.10% of the deviance. GAM analysis also revealed that different algae species responded differently to environmental factors, with the cyanophyta-dominant species Pseudoalgae being more sensitive to TEMP and pH, whereas the chlorophyta-dominant species Chlorella was more affected by wind speed and salinity. Cyanobacteria dominance, exacerbated by warming, increases the risks of harmful algae blooms and ecosystem instability, highlighting the need for mitigation strategies in vulnerable freshwater ecosystems.
Effects and Mechanisms of Higher Education Development on Intelligent Productivity Advancement: An Empirical Analysis of Provincial Panel Data in China
Authors: Liang Pan , Chen Yuancao
Published: December 2024

In the digital economy era, artificial intelligence implementation has accelerated the intellectualization of productive forces, emphasizing the critical relationship between higher education and this transformation. As the primary conduit for developing advanced human capital, the mechanisms through which higher education adapts to and promotes emerging productive forces require systematic examination. This research establishes a theoretical framework demonstrating the synchronous relationship between higher education development and productive force intellectualization, proposing that higher education development provides essential momentum for this transformation. The framework validation employed panel data analysis from 31 Chinese provinces (2012–2022) using fixed-effects (FE) and mediation effect models. The FE model reveals a positive effect coefficient of 1.561 for higher education development on intelligent productive force enhancement (p < 0.01), indicating substantial promotion of productive force intellectualization without saturation effects. Mediation effect analysis confirms the significance of three mediating factors—labor, capital, and technology (p < 0.05)—validating the influence pathways through human capital, material support, and research innovation mechanisms. The research innovation mechanism demonstrates premier efficacy, while material support mechanisms indicate optimization potential. The human capital mechanism, despite its promise, exhibits implementation time lags. These findings suggest prioritizing intelligent technology talent development, enhancing research investment, and strengthening innovation capabilities to advance higher education’s role in productive force intellectualization.
Assessment of a Temperature-Based Artificial Neural Network Designed for Global Solar Radiation Estimation in Regions with Sparse Experimental Data
Authors: González-Plaza Enrique , García David , Prieto Jesús-Ignacio
Published: December 2024

The aim is to evaluate a model of monthly mean global solar radiation based on a simple ANN that uses geographic and temperature data as input variables and is designed for estimations in regions with few radiometric stations. Using data from 414 Spanish stations, the performance of the model is evaluated when both the number and the percentage of data collected for training the network are significantly modified while maintaining the clustering algorithms. The statistical indicators obtained show a compromise between achieving a lower mean error for all stations and limiting the maximum error at each station. In the worst case, the average error is less than 10% for all stations, and the maximum local error only exceeds 20% in less than 2% of the estimates. The least accurate predictions seem to be related to climate types where the clearness index tends to be higher in winter than in summer, which is the case in some locations on the northern Spanish coast. The results are consistent with estimates obtained for 16 non-Spanish stations, selected within the same input data range, suggesting that the variation of the clearness index over the year could be an important factor for local climate characterization.

Published: December 2024

Aiming at addressing the issue of seal failure of connecting threads of injection–production strings in gas storage, a theoretical research study of injection–production strings is conducted. A full-size model of an injection–production string is established by the finite element method, and natural frequency, buckling state, and influence factors are analyzed. Under the condition of ensuring the circumferential expansion displacement of the pipe string, appropriate annular pressure can be used to reduce the stress caused by the buckling of the pipe string. There is a pressure difference between the inside and outside of the curved section of the pipe string, and the larger the radius of curvature, the greater the pressure difference between the inside and outside of the pipe string, and the greater the fluid flow process because of the pressure difference variation caused by the vibration of the pipe string. The pipe string is in a sinusoidal or helical state near the packer position, and it has central symmetry. The variation in the pipe string outside pressure does not affect the position of the symmetric points. The research results can provide theoretical support to understand the mechanical characteristics and vibration mechanism of gas storage injection–production pipe string, identify the main control factors of vibration, and aim in the development of safety control measures.

Authors: Dunseath Chloe , Bova Emma J. , Wilson Elizabeth , Care Marguerite , Cecil Kim M.
Published: December 2024

Using a pediatric-focused lens, this review article briefly summarizes the presentation of several demyelinating and neuroinflammatory diseases using conventional magnetic resonance imaging (MRI) sequences, such as T1-weighted with and without an exogenous gadolinium-based contrast agent, T2-weighted, and fluid-attenuated inversion recovery (FLAIR). These conventional sequences exploit the intrinsic properties of tissue to provide a distinct signal contrast that is useful for evaluating disease features and monitoring treatment responses in patients by characterizing lesion involvement in the central nervous system and tracking temporal features with blood–brain barrier disruption. Illustrative examples are presented for pediatric-onset multiple sclerosis and neuroinflammatory diseases. This work also highlights findings from advanced MRI techniques, often infrequently employed due to the challenges involved in acquisition, post-processing, and interpretation, and identifies the need for future studies to extract the unique information, such as alterations in neurochemistry, disruptions of structural organization, or atypical functional connectivity, that may be relevant for the diagnosis and management of disease.

Published: December 2024

Organophosphorus pesticides are the most extensively utilized agrichemicals in the world. They play a crucial role in regulating crop growth, immunizing against pests, and improving yields, while their unregulated residues exert serious detrimental effects on both the environment and human health. Many efforts have been made in the world to monitor organophosphorus pesticides and solve the issues caused by them. Nanozymes, as one kind of enzyme mimic that is artificially designed to simulate the function of natural enzymes, have aroused a lot of attention due to their unparalleled advantages. Nanozymes inherit both the unique properties of nanomaterials and catalytic functions, which could overcome the limitations inherent in natural enzymes and have great versatile and adaptable application prospects. This review presents a recent advancement in synthesizing multifunctional nanozymes with enzymatic-like activities by using various nanomaterials to degrade and detect organophosphorus pesticides. It mainly encompasses metal-based nanozymes, carbon-based nanozymes, metal–organic-framework-based nanozymes, and single-atom-based nanozymes. Additionally, this paper discusses the potential of nanozymes as novel functional environmental materials.

Published: December 2024

Rotavirus group A (RVA) is a major cause of pediatric acute gastroenteritis (AGE). Vaccination is an effective public health strategy and Angola implemented it in 2014. This hospital-based study aimed to estimate the prevalence of RVA infection and the severity of AGE in children under five years of age treated at six hospitals in Luanda Province. Between April 2021 and May 2022, 1251 fecal samples were screened by an immunochromatographic rapid test (SD Bioline). Data on socio-demographic profile, nutritional status, and clinical assessment were obtained. The association of RVA infection and AGE severity with possible risk factors was evaluated with a binary logistic regression model. Overall, the detection rate was 57.8% and girls tend to be more often infected than boys (55.2%). Infection was more common in the youngest group (1 to 6 months, 60.3%). Important sources of RVA infection were drinking water kept in tanks (57.9%) and private sanitary facilities with piped water (61%). Surprisingly, according to the Vesikari Scale score, the most severe symptoms were observed in children vaccinated with two doses (80.7%). RVA prevalence remains high despite vaccination, and further studies should address the association between infection sources and disease severity, as well as the causes underlying vaccine (un)effectiveness.

Published: December 2024

Progressive multifocal leukoencephalopathy (PML) is a demyelinating disease caused by the JC polyomavirus (JCPyV). Based on the clinical criteria, PML is diagnosed via polymerase chain reaction (PCR) detection of JCPyV DNA in cerebrospinal fluid (CSF) in combination with neurological and imaging findings. Although the utility of CSF JCPyV testing using ultrasensitive PCR assays has been suggested, its potential requires further evaluation. This study retrospectively analyzed the detection performance of ultrasensitive PCR for CSF JCPyV in patients who underwent brain tissue examination based on the pathological diagnostic criteria for PML. Of the 110 patients with pathologically confirmed definite PML or not PML, standard and ultrasensitive CSF testing was performed for 36 and 74 patients, respectively. The sensitivity of ultrasensitive CSF JCPyV testing of the initial specimens was 85%. With the addition of the follow-up testing, this figure increased to 95%. The specificity and false-positive rate of ultrasensitive CSF JCPyV testing, including follow-up, were 100% and 0%, respectively. No statistically significant correlation was observed between CSF and brain JCPyV levels. The results of this study demonstrate the high sensitivity and accuracy of ultrasensitive CSF JCPyV testing and provide essential information for the clinical diagnosis of PML.

Published: December 2024

Background/Objectives: Millions of individuals worldwide continue to experience symptoms following SARS-CoV-2 infection. This study aimed to assess the prevalence and phenotype of multi-system symptoms attributed to Long COVID—including fatigue, pain, cognitive-emotional disturbances, headache, cardiopulmonary issues, and alterations in taste and smell—that have persisted for at least two years after acute infection, which we define as “persistent Long COVID”. Additionally, the study aimed to identify clinical features and blood biomarkers associated with persistent Long COVID symptoms. Methods: We sent a detailed long COVID symptoms questionnaire to an existing cohort of 1258 vaccinated adults (age 18–79 years) who had mild infection (e.g., non-hospitalized) SARS-CoV-2 Delta variant 2 years earlier. These individuals had comprehensive datasets, including blood samples, available for further analysis. We estimated prevalence of persistent long COVID two years post-infection using weighted adjustment (Horvitz–Thompson estimator) to overcome reporting bias. Multivariable logistic regression models were used to determine association of clinical features and blood biomarkers (pre-infection SARS-CoV-2 RBD-IgG, SARS-CoV-2 neutralizing antibodies, and pre-infection and post-infection neurofilament light) with prevalence of persistent long COVID. Results: N = 323 participants responded to the survey, of whom N = 74 (23%) reported at least one long COVID symptom that had persisted for two years after the acute infection. Weighted prevalence of persistent long COVID symptoms was 21.5% (95% CI = 16.7–26.3%). Female gender, smoking, and severity of acute COVID-19 infection were significantly associated with persistent Long COVID. The blood biomarkers assessed were not significantly associated with persistent Long COVID. Conclusions: Among vaccinated adults two years after mild infection with Delta variant SARS-CoV-2, persistent symptoms attributed to Long COVID are extremely common, certain subgroups are at higher risk, and further research into biological mechanisms and potential treatment targets is needed.

Published: December 2024

The concept of “platform technology” gained prominence after the Ebola outbreak and since then has become essential to international vaccine (prophylactic vaccines against infectious disease) regulatory frameworks. Its significance was further amplified during the COVID-19 pandemic, where platform technology enabled the rapid development and approval of vaccines, optimizing regulatory processes, and enhancing global public health responses. As a transformative tool, platform technology streamlines product development, allowing for the reduction in the number of clinical trials or exemption from certain clinical trials and facilitating cross-referencing in regulatory submissions. Despite significant efforts to establish standardized regulatory procedures, challenges remain, particularly in achieving a unified definition and application of platform technology across regions. This paper explores the evolution, applications, and regulatory strategies of platform technology, with a focus on China’s experience in this field. China’s approach, encompassing risk assessment, and the expedited approval of emergency vaccines, offers valuable insights into global regulatory coordination. By analyzing China’s regulatory contributions and international practices, this paper highlights the potential of platform technology to address future pandemics, including “Pathogen X”, and underscores the importance of harmonizing global regulatory efforts to strengthen public health preparedness and response.

Published: December 2024

Background/Objectives: Vaccinating care home staff is essential to protect vulnerable residents by reducing infection risks and creating a safer care environment. However, vaccine hesitancy amongst staff remains a challenge, particularly since the COVID-19 pandemic raised concerns about side effects and vaccination mandates. This study examines how the pandemic influenced flu vaccine hesitancy amongst UK care home staff. Methods: Data were collected from the FluCare trials conducted over the 2021–22 and 2022–23 winter seasons to explore the impact of concurrent mandatory and non-mandatory COVID-19 vaccination policies on flu vaccine uptake. A total of 52 interviews (21 from the feasibility study and 31 from the randomised control trial) were conducted with care home managers and staff. Thematic analysis identified key themes shaping staff attitudes toward flu vaccination. Results: Four central themes emerged regarding the impact of the pandemic on staff attitudes and the contextual influences shaping vaccine hesitance: (i) tension between autonomy and morals in vaccination decisions; (ii) the COVID ‘craze’ and the displacement of the flu vaccine; (iii) the role of the COVID ‘craze’ in staff vaccine fatigue; and (iv) conspiracies, (mis)information, and the significance of trust. Psychosocial theories on decision making and health behaviour were used to further interpret the findings. Conclusions: Our findings suggest that post-COVID-19 interventions in care home setting should address the issues of autonomy, vaccine fatigue, and trust to enhance vaccine uptake. Understanding these factors could support more effective strategies to address hesitancy amongst care home staff in future vaccination campaigns.

Authors: Ceccarelli Andrea , Munafò Gabriele , Sintoni Francesco , Cintori Christian , Gori Davide , Montalti Marco
Published: December 2024

Background: General practitioners (GPs) and primary care units collaborate with Prevention Departments (PDs) to improve immunization by participating in vaccination campaigns, sharing tools, and implementing educational programs to raise patient awareness. This review aimed to identify effective strategies for involving GPs in PD vaccination practices. Methods: A systematic review following PRISMA guidelines was conducted on MEDLINE, TripDatabase, ClinicalTrials, CINAHL, and Cochrane up to January 2024 to identify full-text studies in English evaluating the effectiveness of GP involvement. A meta-analysis was also performed. Results: Of 1018 records, 15 studies were included, with an intermediate quality assessment. Studies originated from the United States (n = 9), Europe (5), Singapore (1), and China (1). Eight studies investigated educational programs for GPs, while seven focused on organizational or technological interventions to enhance immunization practices. Twelve studies reported increased vaccine uptake after intervention. Vaccines addressed included influenza, SARS-CoV-2, pneumococcal, zoster, and trivalent (diphtheria, tetanus, pertussis). Interventions involving GPs in PD vaccination campaigns, focusing on organizational or technological strategies, demonstrated a significant increase in vaccine uptake (OR = 1.15; 95% CI: 1.03–1.27; p < 0.0001; I2 = 96%). Conclusions: GPs emerged as valuable allies for PDs due to their extensive territorial reach and trusted relationships with patients. Additionally, up-to-date organizational and technological tools could play a decisive role in increasing vaccine uptakes. This study, offering valuable insights into the effectiveness of GPs involvement, may be useful to implement similar intervention in different contexts.
Transient Flow Characterization of Rotor–Stator Cavities in Two Through-Flow Modes: Centrifugal and Centripetal
Authors: Yao Yulong , Wang Chuan , Wang Yitong , Ge Jie , Chang Hao , Zhang Li , Li Hao
Published: December 2024

This study investigates the influence of roughness on the transient flow behavior in the chamber based on the performance requirements of the pump rotor–stator chamber, aiming to elucidate the mechanism of roughness in real operating conditions. Three-dimensional models under two types of flow (centrifugal and centripetal) are developed, and transient numerical analyses are performed through numerical simulation and experimental validation. The results show that roughness significantly accelerates turbulence development in centrifugal through-flow, particularly in the middle- and high-radius regions, increasing the turbulent kinetic energy by approximately 18% compared to smooth surfaces. Transient flow analyses indicate that roughness leads to an overall pressure drop of around 10% within the cavity while facilitating the formation of high-pressure zones near the rotor. In centrifugal flow, high-pressure regions develop rapidly in the high-radius area, resulting in a stepped pressure distribution with a peak pressure increase of 12% at the outermost radius. In centripetal flow, the pressure distribution remains more uniform, yet significant pressure rise trends emerge over time, with pressure increasing by 8% due to the presence of roughness. This study presents a systematic analysis of the effects of roughness on transient flow characteristics in rotor–stator cavities across two flow modes for the first time, providing valuable insights for optimizing pump design and performance under real-world conditions.

Published: December 2024

Groundwater contamination with sub-lethal dissolved contaminants poses significant health risks globally, especially in rural India, where access to safe drinking water remains a critical challenge. This study explores the hydrogeochemical characterization and associated health risks of groundwater from shallow aquifers in the Marginal Ganga Alluvial Plain (MGAP) of northern India. The groundwater chemistry is dominated by Ca-Mg-CO3 and Ca-Mg-Cl types, where there is dominance of silicate weathering and the ion-exchange processes are responsible for this solute composition in the groundwater. All the ionic species are within the permissible limits of the World Health Organization, except fluoride (F−) and nitrate (NO3−). Geochemical analysis using bivariate relationships and saturation plots attributes the occurrence of F− to geogenic sources, primarily the chemical weathering of granite-granodiorite, while NO3− contaminants are linked to anthropogenic inputs, such as nitrogen-rich fertilizers, in the absence of a large-scale urban environment. Multivariate statistical analyses, including hierarchical cluster analysis and factor analysis, confirm the predominance of geogenic controls, with NO3−-enriched samples derived from anthropogenic factors. The spatial distribution and probability predictions of F− and NO3− were generated using a non-parametric co-kriging technique approach, aiding in the delineation of contamination hotspots. The integration of the USEPA human health risk assessment methodology with the urbanization index has revealed critical findings, identifying approximately 23% of the study area as being at high risk. This comprehensive approach, which synergizes geospatial analysis and statistical methods, proves to be highly effective in delineating priority zones for health intervention. The results highlight the pressing need for targeted mitigation measures and the implementation of sustainable groundwater management practices at regional, national, and global levels.

Authors: Huang Xinjia
Published: December 2024

This review provides a comprehensive overview of the advancements and challenges of anaerobic digestion technology in waste stream treatment plants under the framework of the circular economy, emphasizing its role in achieving “dual carbon” goals. As climate change intensifies, with waste stream treatment contributing significantly to global emissions, there is a pressing need to optimize energy efficiency and reduce carbon outputs in this sector. Anaerobic digestion is highlighted as a solution for converting organic waste into renewable biogas and digestate, enabling energy self-sufficiency and reducing greenhouse gasses. The study highlights that anaerobic digestion enables the conversion of organic waste into renewable biogas and nutrient-rich digestate, facilitating energy self-sufficiency and significant reductions in GHG emissions. Successful implementations, such as in Weifang, China, demonstrate the feasibility of upgrading biogas into biomethane for local energy use. Advanced technologies like bioelectrochemical methanation and membrane bioreactors enhance biogas production efficiency, while co-digestion proves effective even in challenging conditions. Despite these advancements, the review identifies critical challenges, including high investment costs, technical inefficiencies, and regulatory barriers, particularly in developing countries. This study provides insights into integrating anaerobic digestion with circular economy principles and offers a foundation for future policies and research aimed at achieving carbon neutrality and sustainable waste management.
Beyond survival: a comprehensive review of quality of life in rectal cancer patients
Authors: Jung Won Beom
Published: December 2024

Rectal cancer is one of the most common carcinomas and a leading cause of cancer-related mortality. Although significant advancements have been made in the treatment of rectal cancer, the deterioration of quality of life (QoL) remains a challenging issue. Various tools have been developed to assess QoL, including the Functional Assessment of Cancer Therapy-Colorectal (FACT-C) scale, the QLQ-C30 and QLQ-CR29 by the European Organization for Research and Treatment of Cancer (EORTC), and the 36-Item Short Form Health Survey (SF-36). Factors such as the lower location of the tumor, radiation therapy, chemoradiotherapy, and chemotherapy are associated with a decline in QoL. Furthermore, anastomotic leakage following rectal cancer resection is an important risk factor affecting QoL. With the development of novel treatment approaches, including neoadjuvant therapies such as chemoradiotherapy and total neoadjuvant therapy, the rate of clinical complete remission has increased, leading to the emergence of organ-preserving strategies. Both local excision and the “watch-and-wait” approach following neoadjuvant therapy improved functional outcomes and QoL. Efforts to improve QoL after rectal cancer surgery are ongoing in surgical techniques for rectal cancer. Since QoL is determined by a complex interplay of factors, including the patient's physical condition, surgical techniques, and psychological and social elements, a comprehensive approach is necessary to understand and enhance it. This review aims to describe the methods for measuring QoL in rectal cancer patients after surgery, the key risk factors involved, and various strategies and efforts to improve QoL outcomes.

O Impacto na cadeia produtiva do turismo de Juiz de Fora (MG): análise da dinâmica demográfica organizacional e dos fatores contingenciais do segmento hoteleiro e de suas estratégias de sobrevivência no contexto pandêmico (2020- 2022) na percepção de seus gestores
Authors:   , Freesz Stela
Published: December 2024

A pandemia trouxe implicações para todas as sociedade e setores econômicos, em especial para o setor do turismo. Sabe-se que os fatores demográficos organizacionais e contingências influenciam o desenvolvimento de todos os setores da economia. Esta pesquisa, então, se desenvolve a partir da seguinte questão: como os fatores contingenciais derivados do contexto produzido pela pandemia de SARSCOV-19 impactaram na seleção demográfica organizacional do setor hoteleiro de Juiz de Fora e quais eventuais respostas organizacionais, por meio de ações, práticas e estratégias gerenciais de adaptação destas empresas? Para tanto, recorreu-se às teorias da Teoria da Contingência e da Ecologia Organizacional para, por meio do mapeamento do perfil demográfico do segmento hoteleiro de Juiz de Fora, identificar os fatores demográficos organizacionais e contingenciais do setor hoteleiro de JF e em que medida se relacionam com as ações, práticas e estratégias gerenciais de adaptação e seleção das empresas em face dos fatores contingenciais produzidos por este “novo ambiente” contexto derivado da pandemia de SARSCOV-19. Optou-se por uma metodologia mista de pesquisa, que engloba aspectos qualitativos e quantitativos. A parte quantitativa refere-se aos dados secundários da pesquisa, enquanto a qualitativa refere-se aos dados primários. Da população de empreendimentos existentes, ao todo 49 estabelecimentos no setor hoteleiro de Juiz de Fora, a amostra final foi de 18 organizações estudadas, mediante entrevistas realizadas com os seus gestores (executivos) principais, sendo, portanto, esta uma limitação da pesquisa. Fez-se a coleta de dados através de entrevista e técnica de bola-de-neve para a seleção de respondentes. Posteriormente os dados foram organizados por meio de planilhas e analisados usando a técnica de análise de conteúdo, a qual permitiu a realização de cruzamentos e triangulação de fontes e resultados. Os resultados indicam que os hotéis sofreram grande impacto com a pandemia e que seja pelo fechamento de empresas seja por restrições do contexto, levou-se o segmento hoteleiro a uma adaptação forçosa no momento da pandemia e no pós-pandemia, dentre as quais destacam-se: a) a necessidade de melhor compreender o perfil do novo cliente, b) adoção de estratégias diferentes de sobrevivência, c) corte de custos e de pessoal e reduções de valores dos serviços, d) recebimento de auxílio do governo e e) adoção de TIC’s e divulgação nas redes sociais. Percebeu-se ainda que eles atuam de forma independente e competem entre si o que dificulta, em parte, o desenvolvimento do setor uma vez que a comunicação possuí ruídos. Conclui-se que pandemia impactou o setor levando assim o setor a estabelecer um novo padrão de atuação, quiçá mais precarizado de relações laborais.
Anomalias de mercado: PEAD e crescimento/valor como ferramentas de análise fundamentalista no mercado acionário brasileiro

Published: December 2024

Este trabalho teve como objetivo verificar se a junção de critérios fundamentalistas com o PostEarnnings Announcement Drift (PEAD) foi capaz de elevar a rentabilidade de uma carteira, via estratégias de compra e venda de ações de crescimento e valor. Dessa maneira, as anomalias PEAD e crescimento/valor foram representadas pelas variáveis Standardized Unexpected Earnings (SUE) e Preço/Valor Patrimonial (P/VPA). Ademais, as ações de crescimento e valor receberam critérios fundamentalistas, sendo chamadas, respectivamente, de BrG_Score e BrF_Score. Ao todo, esta dissertação utilizou os dados trimestrais de 309 companhias listadas ou já listadas na Brasil, Bolsa, Balcão (B3), compreendendo o horizonte temporal do primeiro trimestre de 1994 ao quarto trimestre de 2021. Com base nas evidências empíricas encontradas, pode-se inferir, de forma geral, que a conjugação do PEAD com o crescimento/valor, tendo em vista os critérios fundamentalistas, pode aumentar a rentabilidade dos portfólios e ser útil para os agentes do mercado (tendo em vista apenas o teste de médias), sendo esta a principal contribuição da pesquisa. Todavia, o modelo econométrico testado não ofereceu valores suficientes para ser validado estatisticamente.

O objetivo deste estudo é analisar como o discurso dissidente baseado em gênero é utilizado na campanha publicitária “Todos podemos cuidar” da Linha de bonecas Baby Alive. Para alcançar isso, identifica e descreve o enunciador (a fabricante de brinquedos Hasbro) de acordo com suas práticas econômicas, sociais e discursivas; destaca os recursos de comunicação usados no vídeo que o caracterizam como parte de um discurso dissidente; avalia o impacto do vídeo em outros meios de comunicação e busca compreender como a empresa se apropria de elementos do discurso dissidente baseado em gênero para fins de legitimação organizacional. O estudo concluiu que houve a utilização de discurso dissidente com fim de legitimação organizacional e que para minimizar as repercussões negativas do uso desse discurso, a publicidade associou a boneca a valores já aceitos na sociedade, como a educação e o cuidado. Além disso, sua audiência foi limitada a um grupo que já apoiava o brincar não sexista, e a construção narrativa da publicidade se utilizou de hiperônimos e hipônimos, quando começou tratando as crianças como iguais, diferenciando-as com base em seu gênero à medida que a narrativa avançava
Avaliação do efeito dos atributos do ambiente construído na disseminação da Covid-19 na área urbana de Juiz de Fora – Minas Gerais, no ano de 2020

Em dezembro de 2019, as autoridades chinesas informaram à Organização Mundial de Saúde (OMS) sobre pacientes diagnosticados com pneumonia de causa desconhecida em Wuhan, província de Hubei. Tratava-se de um novo coronavírus que, devido à alta capacidade de transmissão e do grande fluxo de viagens internacionais, difundiu-se mundialmente. Embora as investigações iniciais para compreender a dinâmica de transmissão do vírus nas cidades estejam em andamento e apontam para uma possível correlação com atributos do ambiente construído, essas discussões são mais frequentes em países desenvolvidos. No Brasil, apesar das pesquisas contemplarem análises da vulnerabilidade das cidades em decorrência das desigualdades socioeconômicas nos grandes centros urbanos, verifica-se a carência de estudos para compreender a relação entre as características espaciais urbanas e a distribuição e infecção da Covid-19 nas cidades não metropolitanas. Para preencher esta lacuna, este estudo explora a existência de correlações entre os atributos do ambiente construído e a disseminação da Covid-19 na área urbana de Juiz de Fora ao longo do ano de 2020. Os dados sobre os infectados e os atributos do ambiente construído foram disponibilizados pelo Departamento de Vigilância Epidemiológica e Ambiental e pela Secretária de Planejamento Urbano da Prefeitura de Juiz de Fora, respectivamente. Agrupamentos espaciais significativos de casos pela cidade foram identificados através do teste do Índice de Moran univariado pelo software de análise de dados espaciais GeoDa. Posteriormente, o número de casos e os atributos do ambiente construído foram correlacionadas utilizando um modelo estatístico de regressão espacial. Os resultados sugerem um padrão heterogêneo na distribuição da infecção e a formação de aglomerados espaciais significativos nas fases 1, 2 e 3. Além disso, determinantes demográficas, de infraestrutura do transporte público e de mobilidade urbana foram significativas para explicar a incidência de Covid-19 nos setores censitários. A avaliação da dinâmica da Covid-19 e sua correlação com atributos do espaço urbano é importante para promover a articulação de políticas públicas relacionadas ao planejamento urbano em relação aos agravos de saúde. Nesse caso, os resultados desta pesquisa contribuíram para o entendimento do comportamento da infecção da Covid-19 em relação à malha urbana e poderão subsidiar a elaboração de políticas sociais, ambientais, de saúde, econômicas pelo poder público e criar um banco de dados para a cidade.
O ensino de projeto de arquitetura e urbanismo e a primazia da visualidade
Authors:   , Rosa Cleyton Luiz da Silva

O mundo atual tem sido marcado por um crescente valor atribuído à imagem e à visualidade, e a área da arquitetura e urbanismo não é exceção. Nesse contexto culturalmente visual, arquitetos e urbanistas recebem formação acadêmica que prioriza a imagem, resultando em profunda primazia da visualidade nos métodos e técnicas da área de arquitetura e urbanismo. Portanto, a pesquisa buscou responder à seguinte questão: Existe, para os professores de arquitetura e urbanismo, a possibilidade de um ensino de projeto de arquitetura e urbanismo para além da visualidade? A investigação teve como objetivo compreender os discursos dos professores das escolas de arquitetura e urbanismo sobre a possibilidade de um ensino de arquitetura e urbanismo para além da visualidade, especialmente no núcleo de conhecimento “Projeto de Arquitetura, de Urbanismo e de Paisagismo”. A metodologia foi composta pela revisão de literatura e documental, aplicação de questionário e entrevista, cujos dados foram manipulados através da técnica francesa da análise do discurso. Ao final, concluiu-se que a primazia da visualidade no campo da arquitetura e urbanismo é amplamente presente e enraizada. São percebidas algumas contradições nos discursos: por um lado, é mencionada a possibilidade de um arquiteto e urbanista sem a visão atuar e aprender arquitetura, por outro lado, na prática pedagógica e nos recursos utilizados, ainda predominam formas de representação exclusivamente visuais, trazendo consigo algumas perdas e limitações ao desenvolvimento pleno de todos, isto é, tanto para uma pessoa com visão, quanto sem ela. Essas contradições revelaram a necessidade de um maior esforço e uma reflexão contínua no campo da arquitetura e urbanismo para superar a supremacia da visualidade e desenvolver abordagens mais inclusivas e sensíveis aos sentidos. Portanto, devido a essa ênfase na visualidade, reforçada nos discursos, não parece existir uma perspectiva evidente para os professores de arquitetura e urbanismo em relação à possibilidade de um ensino de projeto de arquitetura e urbanismo que vá além da visualidade, uma vez que os discursos dos professores e também as teorias, métodos e técnicas da área reforçam essa restrição significativa do desenvolvimento sem a visualidade.
Seleção preliminar de áreas para instalação de unidade de gerenciamento de resíduos sólidos para o Município de Cataguases – Minas Gerais

Published: December 2024

Este estudo teve como objetivo realizar uma análise preliminar de possíveis áreas adequadas para a implantação de um novo aterro sanitário no município de Cataguases. Além disso, buscou-se realizar uma análise crítica da gestão de resíduos sólidos municipal e traçar suas perspectivas futuras. A metodologia adotada consistiu na elaboração de mapas para identificar áreas propícias e impróprias para a implantação do aterro sanitário, levando em consideração critérios estabelecidos pela NBR 15849, Resolução CONAMA n° 404/2008 e COPAM nº 118/2008. Foram considerados aspectos como declividade, presença de cursos d'água, restrições ambientais, ferrovias e rodovias. Os resultados obtidos revelaram a identificação de uma grande área imprópria para a implantação do aterro sanitário em Cataguases, de acordo com os critérios técnicos estabelecidos. Essa identificação é crucial para garantir a eficiência e a sustentabilidade do sistema de gerenciamento de resíduos sólidos, bem como para a preservação do meio ambiente e a proteção dos recursos hídricos. No entanto, também foram encontradas várias áreas sem restrições, que oferecem opções viáveis para a instalação do aterro sanitário de acordo com a legislação vigente. Essas áreas apresentam características favoráveis, como declividade adequada, ausência de proteção de cursos d'água e nascentes, além de estarem livres de restrições ambientais, ferrovias e rodovias. A conclusão do estudo destaca a importância da escolha adequada da localização do aterro sanitário, levando em consideração apenas os critérios técnicos. Essas informações são fundamentais para contribuir para a garantia da eficiência do sistema de gerenciamento de resíduos sólidos, bem como para a minimização dos impactos negativos.
