Strategies for Intervention and Prevention in Online Child Sexual Exploitation
Authors: Ali Muhammad Imran
Published: September 2024

Online child sexual exploitation (OCSE) is a significant societal and technological problem that ought to be addressed immediately. This article broadly deals with the intricate complexity of OCSE, laying bare the identities and behaviors of online predators, the characteristics of virtual playgrounds, and the adverse consequences for victims. Virtual offenders, by taking advantage of the anonymity of internet spaces, mostly use a variety of tactics to approach vulnerable children. These tactics demand thorough assessment to work out and deliver effective interventions. Virtual environments, such as game communities and chat rooms, have become the perfect hunting grounds for predators, which accentuates the crucial need for preventive measures. Nonetheless, technology gives reason for optimism about the elimination of OCSE despite the challenges of scale and precision. This article, therefore, conducts an in-depth analysis of the issue of online child sexual exploitation and offers comprehensive interventions as a way of increasing knowledge and mobilizing action to shield children from online child sexual exploitation.
GOGOL’S REINCARNATIONS
Authors: Vinogradov Igor’
Published: September 2024

The article examines one of the cardinal features of Gogol’s legacy, which endows the writer’s works with their key feature — a sense of truly “living life.” The maximum realism of Gogol’s fiction is rooted in his capacity for deep figurative, syncretic thinking. Based on numerous testimonies, it is proven that the success among readers and viewers of dozens of “roles” that Gogol recreated and “played” through his stage and literary heroes lies in his exceptional gift for creative reincarnation, as well as in his extreme confessional nature, which together constitute a unique property of his genius. Gogol’s legacy expands the boundaries of traditional ideas about reincarnation, which is often considered exclusively an actors’ skill. In the Gogol context, this concept embraces numerous areas of creativity and even extends to a person’s choice of his calling in life — the definition of the “role” with which he enters the general culture. Gogol’s various self-definitions are manifested in his initial choice of his life path, when in the 1820s — early 1830s he successively “tried on” the professions of a lawyer, artist, historian, geographer, etc. The theater stage seemed to him to be one of the areas of application of his talents at that time. Creative “entries into character” were later required for Gogol’s artistic and teaching activities — literary pursuits and historical studies, the latter of which also imply an “acting” transformation — thinking and acting “for” emperors, kings, caliphs, hetmans and other world history personas. The wide range of application of Gogol’s diverse abilities and his deep rootedness in pan-Christian symbolism, the traditions of which he absorbed in his youth in the family and at school, logically determined the realistic, deeply conscious nature of his work

Published: September 2024

Introduction. Today, there is a need for a shared vision of restoration of disturbed ecosystems, which is defined as “the process of stopping and reversing degradation, leading to improved ecosystem services and restoration of biodiversity.”Problem Statement. The assessment and restoration of disturbed ecosystems has become especially relevant for the Ukrainian society now, as warfare has caused large-scale changes in environment and both short-term and long-term consequences for ecosystems in Ukraine.Purpose. Assessment of ecosystems disturbed as a result of warfare impact by remote sensing.Materials and Methods. Multispectral satellite imagery, ground truth data and ecosystems characteristics of study area have been used. Remotely sensed data processing, geospatial modelling, and mathematical statistics have been applied.Results. A warfare impact on the ecosystems of Ukraine has been overviewed. Possibility of using remote sensing methods have been considered; their advantages and disadvantages have been generalized. A demo example of the described technique for assessing the ecosystem conditions along the E40 highway on the west of Kyiv has been shown with the use of multi-time satellite imagery of very high resolution (0.5 m on the ground) between May 2020 and March 2022. The analysis of the obtained maps allows us to assess short-term changes in land cover: a decrease in the area of water bodies, coniferous and leafy plants, an increase in the open soil area. The ecosystem conditions map of the studied area enables identifying plots of high risk.Conclusions. Integrated remote assessment of the condition of disturbed ecosystems and geospatial analysis of corresponding risks are useful tools for the territory management. Remote sensing techniques are particularly important in the context of largescale warfare. In many cases, only remote sensing techniques can provide information on the condition of ecosystems that areinaccessible or dangerous for ground-based research. Currently, the proposed approach has been elaborated and tested over other territories, different ecosystems and other data sources. Completed and tested integral geo-information technology will be relevant for the post-war recovery of the territory of Ukraine. Further research should be focused on building a pool of quantitative models for probabilistic assessment of the risk of disruption of various ecosystems under diff erent conditions, as well as on obtaining an array of statistical data to increase the reliability of the resulting maps.

Published: September 2024

Introduction. The introduction of energy-saving technologies has become particularly relevant in recent years, when energy prices have been constantly increasing. This is particularly important for greenhouse farms, where the main condition for growing plants indoors is the creation of artificial climatic conditions: temperature, humidity, and lighting.Problem Statement. Given the light and the dark stages of photosynthesis, it becomes possible to use a variable light field in the plant-growing photoculture, which is created by light installations with variable radiation. The development of an energy-saving electric drive and automated control systems for the parameters of artificial climatic conditions when growing plants indoors results in reducing energy consumption and increasing the reliability of the technological process in greenhouses of agro-industrial complex.Purpose. Implementation of energy-saving variable illumination irradiating systems with an automated control system for greenhouse farms.Materials and Methods. A lighting installation with rotation of the irradiator in the vertical and horizontal planes with a discrete electric drive and microprocessor control has been used.Results. The current state of variable irradiating systems with energy-saving radiation sources has been analyzed. The use of a discrete electric drive with an automated control system has been proposed. The installation with a DNAT-400 radiation source and a ZHO-01 reflector enables irradiating an area of up to 100 m2. The maximum exposure to photosynthetically active radiation is 30 W/m2, and the irradiation irregularity does not exceed 20%. At the same time, electricity savings reach about 10 thousand kWh per season. The yield and quality of products remain unchanged.Conclusions. The results of the research have confirmed the feasibility of practical implementation of variable irradiation system for energy efficiency of greenhouse operations.

Does the Merger of the Indonesian Islamic Bank Matter for Its Social Mission of Economic Empowerment?
Authors: Isman Ainul Fatha , Hidayah Nur
Published: September 2024

Research Originality: Economic empowerment through financing Micro Small Medium Enterprises (MSMEs) is one dimension of the social mission of sharia banking in Indonesia. The merger action of Bank of Sharia Indonesia (BSI) raises the question of whetherthe performance of economic empowerment has changed.Research Objectives: This research aims to analyse the differences in the BSI’s performance of economic empowerment during preand post-merger periods and analyse the issues and strategies for improving BSI's post-merger economic empowerment performance.Research Methods: It is a research using mixed method combining a quantitative explorative analysis approach using Wilcoxon Test, and a qualitative one using Analytic Network Process.Empirical Results: This research finds that BSI's economic empowerment performance has increased in terms of the quantity but decreased in terms of proportion in the post-merger period. ANP research demonstrates that risk management is a priority issue for the BSI post-merger period. The social mission of economic empowerment indicates several priority issues, namely, the relatively higher rate of profit margin than interest, the inadequate supervision model, the low rate of risk management literacy, and the relatively higher risk of profit loss sharing (PLS)-based financing. The strategy analysis indicates that policy intervention for BSI’s MSMEs financing is a top priority in improving the performance of its economic empowerment.Implications: This research recommends some recommendations for sharia banks’ MSMEs financing equivalent to the one of conventional banks. Economic digitalization as technological means to widen accessibility of economic empowerment and distribution segmentation focusing more on the halal sector.JEL Classification: A13, G21, G34How to Cite:Isman, A.

Published: September 2024

The purpose of this research was to characterise the echogenicity of the different structures within the scrotal bag in rams. Three studies that included 43 rams were conducted. Ultrasound sections (US) were made with the Mindray® equipment. It was found that pubertal males showed greater echogenicity (P<0.05) in testes and the pampiniform plexus, whereas prepubertal males (P<0.05) - in the epididymis and in the right pampiniform plexus. Rams in mating showed the highest echogenicity values (P<0.05). In non-mating animals, the highest values were found in the epididymis (P<0.05). Rams with injuries presented higher echogenicity in testes (P<0.05). In pampiniform plexuses, males without injuries demonstrated the highest values (P<0.05). A high and positive correlation (P<0.0001) was found between the evaluated variables, specifically the right cranial longitudinal (RCL), right proximal transverse (RPT), right medial transverse (RMT), right distal transverse (RDT) measures. Echotexture in rams was affected by age, presence of injuries and sexual activity. In addition, the high correlation suggests that the evaluation of testicular health in rams could be carried out only with several US.
A experiência da discricionariedade: um estudo com membros das carreiras de gestão
Authors: Santos Carolina Soares dos , Rodrigues Andrea Leite , Prado Milton Morassi do
Published: September 2024

Resumo A discricionariedade dos agentes públicos vem ganhando importância como objeto de estudo por ser questão relevante na gestão e implementação de políticas públicas. Servidores públicos enfrentam decisões discricionárias de formas variadas, indo desde a construção de modos criativos para gerar bons impactos sociais até, no limite extremo, à inação, por medo de posterior responsabilização por conduta considerada indevida. Este estudo buscou compreender a experiência da discricionariedade para os servidores de carreiras de gestão e os dilemas existentes nessa atuação. Para tanto, procedeu-se a pesquisa qualitativa com especialistas em políticas públicas do estado de São Paulo e gestores governamentais do estado de Pernambuco. A pesquisa de campo englobou coleta por meio de 5 grupos focais. Na sequência, os dados foram analisados por meio da técnica da análise de conteúdo. Identificou-se que o principal dilema enfrentado pelos burocratas se encontra entre decidir dentro de sua competência e no melhor de seu conhecimento ou a inação, por medo de responsabilização, caso a decisão seja julgada como ilegal ou de má-fé. Por consequência, tem-se o chamado “apagão das canetas”. Há um constante trade-off entre a discricionariedade e a responsabilização, havendo meios pelos quais os servidores se valem para atenuar os riscos de sofrer sanções.
Evaluation of the organizational culture in public health centers of different complexity in Chile
Authors: Cancino Víctor Eduardo Cancino , Yáñez Carlos Salvador Mellado
Published: September 2024

Abstract The article analyzes the organizational culture in public health institutions in Chile, establishing the relationship between the organizations’ cultures and their level of complexity and coverage using the Denison Organizational Culture Scale. The scale was applied to a sample of 156 workers from four institutions. The results reveal that institutions with low complexity and coverage showed higher cultural levels in all dimensions: involvement, consistency, adaptability and mission; as well as in the perspectives of flexibility/stability and internal/external focus. Alternatively, responses from workers in institutions with high coverage but different complexity did not show significant differences regarding their understanding of the organizational culture. In addition, the findings highlight the relationship between the functional characteristics associated with the complexity of health organizations and their cultural features, evidencing particular differences according to the level of coverage or intensity of demand for the services they provide, as well as perspectives of flexibility and stability according to the Denison model.
O espaço da politização na estrutura do Governo Federal brasileiro, 1999-2021
Authors: Faraco Junior Antônio Luiz Arquetti
Published: September 2024

Resumo: Qual foi o tamanho do espaço que o presidente brasileiro possuiu para politizações na estrutura da burocracia pública federal no período 1999-2021? Considerando que o tamanho desse espaço está relacionado à importância da politização como estratégia de controle da burocracia, de monitoramento de parceiros e de acomodação política, conforme a lógica do presidencialismo de coalizão, este artigo procurou dimensioná-lo empregando metodologia descritiva, baseada em coleta de dados obtidos do Painel Estatístico de Pessoal do governo federal, abrangendo cargos e funções do governo federal ao longo do período em questão. Ao considerar todas as possibilidades de nomeações e designações efetuadas pelo presidente para cargos e funções da alta gestão, este artigo apresentou uma abordagem inovadora em relação a outras análises previamente desenvolvidas no âmbito da Ciência Política brasileira, no que tange à avaliação do fenômeno da politização no governo federal. Tal abordagem permitiu concluir que o tamanho do espaço para politização não diminuiu substantivamente com a redução de cargos DAS, além de revelar um novo padrão da politização, marcado pelo maior uso das funções de confiança, desempenhadas exclusivamente por servidores de carreira e pela valorização desses servidores também entre as nomeações para cargos DAS.
Identifying tax evasion in shell companies and fraudulent credits of Brazil’s state value-added tax (ICMS)
Authors: Gomes Gunther Siqueira Lemos , Balaniuk Remis
Published: September 2024

Abstract Companies that issue tax documents to defraud the tax authorities with the transfer of credits of Brazil’s state value-added tax (ICMS) without the movement of goods cause financial losses to the government and, therefore, to society as a whole. Several initiatives to combat tax fraud have successfully used data analysis and Machine Learning techniques. This work sought to investigate the use of these techniques in identifying a specific practice of tax fraud, practiced by shell companies, formed exclusively to issue non-due ICMS credits, the tax on operations related to the circulation of goods, and the provision of interstate, intercity, and communication services. Based on document analysis and consultation with auditors and specialists, typologies and variables relevant to identifying tax evasion events carried out by shell companies were identified. Around these variables, data from the Finance Department of the Federal District were collected and prepared. With this data, it was possible to explore the use of predictive models based on Machine Learning capable of pointing out potentially fraudulent behavior. The good results obtained by these models demonstrate their potential as part of systematic monitoring and fiscal audits by tax authorities.
Influências do suporte técnico e dos controles gerenciais no desempenho de tarefas no teletrabalho
Authors: Cordova Bruna Cristina , Santos Edicreia Andrade dos , Sallaberry Jonatas Dutra , Mendes Alcindo Cipriano Argolo
Published: September 2024

Resumo Este estudo verificou as influências dos controles gerenciais de ação e de resultado na relação entre suporte técnico ao teletrabalho, desempenho de tarefas e congruência de objetivos. Os dados foram coletados por meio de uma survey single entity, com 468 servidores de um órgão de Justiça, e analisados por meio de equações estruturais. Os achados mostram que o suporte técnico ao teletrabalho influencia positivamente os controles de ação e de resultado, o desempenho de tarefas e a congruência de objetivos. Evidenciou-se também que os controles de ação interferem positivamente no desempenho de tarefas e na congruência de objetivos, enquanto os controles de resultado influem, de forma direta ou por mediação, apenas na congruência de objetivos. Depreende-se que, os controles de resultado não afetam o desempenho de tarefas, pois precisam de revisão para alinhamento ao contexto de teletrabalho ou, alternativamente, que os servidores não precisam desse tipo de controle para apresentar bons desempenhos.
Influences of technical support and management controls on the performance of teleworking tasks
Authors: Cordova Bruna Cristina , Santos Edicreia Andrade dos , Sallaberry Jonatas Dutra , Mendes Alcindo Cipriano Argolo
Published: September 2024

Abstract This study looked at the influence of action and results management controls on the relationship between technical support for teleworking and task performance and goal congruence. The data was collected through a single-entity survey of 468 civil servants from a unit of Justice and analyzed using structural equations. The findings show that technical support for teleworking positively influences action and results controls, task performance, and goal congruence. It was found that action controls positively influence task performance and goal congruence, while outcome controls only directly or through mediation influence goal congruence. It appears that results controls do not affect task performance because they need to be revised to align them with the teleworking context or, alternatively, that civil servants do not need this type of control to perform well.
Analysis of profiles of organizational links among public servers
Authors: Rangel Sara Barbosa , Rowe Diva Ester Okazaki
Published: September 2024

Abstract The aim of this article is to outline the organizational commitment and entrenchment profiles of civil servants from the Brazilian Federal Revenue Office, comparing sociodemographic and occupational variables in the identified profiles. A quantitative, descriptive, cross-sectional study was carried out, collecting data via an online survey responded by 1,126 civil servants. Latent profile analysis was used to study the data, revealing four distinct organizational attachment profiles: i) moderately attached; ii) low attachment (predominantly uncommitted); iii) low attachment; iv) attached (predominantly committed). Most of the participants belonged to profiles with moderate and high levels of affective commitment. A shorter length of service and younger age predicted low attachment profiles, while senior positions were associated with profiles with higher levels of commitment and adjustment to social position (a dimension of entrenchment). Identifying these differences in profiles is a relevant contribution to more personalized and focused management of people and relationships.

Published: September 2024

Resumo Este artigo investiga os fatores referentes ao desempenho da função de compras da Receita Federal do Brasil (RFB), sob a perspectiva de dimensões de sua estrutura organizacional. Para tanto, a estratégia metodológica consistiu no levantamento de dados da RFB. Por meio de técnicas de sumarização e regressão, identificaram-se variáveis associadas à centralização, à formalização e à especialização da estrutura de compras, bem como suas relações com o desempenho da função na instituição. Os resultados indicaram relações significativas e positivas entre centralização e medidas de desempenho relativas ao tempo. Em contraste, a especialização ocupacional, em níveis intermediários, se associou de forma negativa com a competição, enquanto a experiência acumulada na área de compras se associou positivamente com os prazos de licitação. A formalização, por sua vez, apresentou associações que indicam um trade-off entre recursos financeiros e tempo. Consectuvamente, a pesquisa contribui para o campo da administração pública ao investigar a estrutura e o desempenho em compras numa instituição brasileira com atuação nacional, perscrutando hiatos identificados em artigos nacionais e internacionais, como os relativos ao país, à abrangência e à diversidade das compras analisadas, interpretando aspectos causais dessas associações.

Authors: Pinto Arthur Vinicius da Costa Ferreira , Monteiro Doraliza Auxiliadora Abranches , Reis Paulo Ricardo da Costa
Published: September 2024

Abstract This article investigates the performance of the Brazilian Federal Revenue Service’s (FRS) procurement function from the perspective of the dimensions of its organizational structure. Using data collected from the FRS, the methodological strategy consisted of summarization and regression techniques, identifying variables linked to the centralization, formalization, and specialization of the procurement structure, and the relationship of these elements with its performance. The results indicated significant and positive relationships between centralization and time-related performance measures. In contrast, occupational specialization at intermediate levels was negatively associated with competition, while accumulated experience in the procurement area was positively associated with bidding times. Formalization showed associations that indicate a trade-off between financial resources and time. Consequently, the research contributes to the field of public administration by investigating the structure and performance of procurement in a Brazilian institution with national operations, looking into gaps identified in national and international articles, such as those related to the country, scope, and diversity of the purchases analyzed, and interpreting the causal aspects of these associations.

Authors: Bernabe-Ortiz Antonio , Carrillo-Larco Rodrigo M.
Published: September 2024

Abstract: This study aimed to estimate the population-based Parkinson disease prevalence, and to explore potentially associated factors and conditions. A population-based survey was conducted in Northern Peru. Symptoms compatible with Parkinson’s were defined using a validated Spanish questionnaire (≥ 42 points suggest Parkinson’s). Potential factors (e.g., age, sex, etc.) and clinical conditions (e.g., depressive symptoms, perceived stress, etc.) associated with Parkinson’s were assessed. In total, 1,609 subjects were included, mean age of participants was 48.2 (SD: 10.6), and 810 (50.3%) were women. Parkinson’s prevalence was 1.6% (95%CI: 1.0; 2.4). Those aged ≥ 55 years, and those who reported using wood as fuel for household cooking had a Parkinson’s prevalence from 3.5 to 4 times greater than those who did not. The presence of depressive symptoms, anxiety symptoms, perceived stress, poor sleep quality, and cognitive impairment was more common among those with Parkinson’s, and quality of life in these participants was lower than those without Parkinson’s. In conclusion, 1.6% of the population shows symptoms compatible with Parkinson’s. Age and use of wood for household cooking were factors associated with Parkinson’s. Several mental health conditions and lower quality of life were more frequent among those with Parkinson’s. Appropriate strategies are required to detect, prevent, and manage Parkinson’s cases.

Published: September 2024

A tuberculose (TB) é uma doença infectocontagiosa que ainda representa um grave problema de saúde pública no mundo. Na população pediátrica, os fatores que levam ao abandono do tratamento da TB, especialmente em regiões de elevada prevalência da doença, são pouco conhecidos. Portanto, este estudo objetivou identificar a prevalência e os fatores de risco associados ao abandono do tratamento da TB em crianças e adolescentes. Foi realizado um estudo transversal com dados obtidos das notificações de TB provenientes do Sistema de Controle de Pacientes com Tuberculose do Estado de São Paulo, Brasil, em indivíduos com idade entre 0 e 18 anos, no período de janeiro de 2009 a dezembro de 2019. Estimou-se a razão de prevalência bruta e ajustada com intervalo de 95% de confiança, utilizando-se o modelo de regressão de Poisson para identificar associações entre o desfecho abandono do tratamento com os fatores sociodemográficos, clínico-epidemiológicos, diagnósticos e terapêuticos dos casos de TB, contendo informações completas. Dos 12.256 casos analisados, 941 indivíduos abandonaram o tratamento. A maior taxa de prevalência de abandono do tratamento ocorre entre os adolescentes pretos ou pardos, acima de 11 anos e privados de liberdade. Outras características associadas ao abandono do tratamento incluem: serem pessoas vivendo com HIV/aids, ter histórico de tratamento anterior para TB, fazer uso de substâncias ilícitas e utilizar o regime de tratamento de TB autoadministrado. Concluiu-se que conhecer o perfil do paciente com maiores chances para abandonar o tratamento da TB permite elaborar estratégias focadas na adesão ao tratamento medicamentoso mais efetivas.

Abstract This study aimed to assess the fatigue resistance of molars lacking a coronary remnant, using zero, one, two, or three fiberglass posts. Forty caries/crack-free human molars with coronal portions removed at the pulp chamber floor were randomly allocated into four groups (n=10). Following endodontic treatment, posts (Whitepost DC/DC.E 0.5, 1.0, FGM) were silanized (silane agent, Angelus) and cemented with a resin cement (RelyX U200, 3M ESPE). Resin composite cores (Z350, 3M ESPE) were built, and metal crowns were fabricated and cemented using the same luting system. Samples underwent cyclic fatigue testing at 45°, applying load in the occlusal surface at 10 Hz and 100 N initial load for 10,000 cycles, with 50 N increments every 10,000 cycles until failure. Fatigue failure load and cycles for failure data were recorded and subjected to survival analysis through Kaplan-Meier and Mantel-Cox post hoc tests, and Weibull analysis. Fractography patterns of failed crowns were qualitatively analyzed. The group without posts exhibited the lowest fatigue performance (p < 0.05) for both fatigue failure load and cycles to failure. Superior fatigue performance was observed in the three-post group, followed by groups with one or two posts, corroborated by the Weibull characteristic strength parameter. Weibull moduli were similar among conditions. All specimens exhibited failure involving detachment of the restorative set (posts/core/crown) with a portion of the dental remnant, without tooth fracture. Thus, when restoring mandibular molars without crown remnants, the use of fiberglass posts promotes greater fatigue resistance to oblique loads.

Abstract This study aimed to evaluate the effect of in vitro immersion solutions or an in vivo method on volumetric change of bioceramic root repair materials: Bio-C Repair (BCR, Angelus, Londrina, PR, Brazil) and Biodentine (BIO, Septodont, Saint-Maur-des-Fossés, France) compared to IRM (Dentsply Sirona, York, Pennsylvania, USA) by using microcomputed tomography (µCT) assessment. Tubes of polyvinyl chloride (PVC, 4 mm of length x 1.3 mm of inside diameter, n = 7) were filled with the materials for volumetric analysis in µCT. Samples were scanned after materials setting and after immersion in distilled water, PBS, or in vivo tissue fluid of subcutaneous tissue of rats for 7 days. IRM showed higher volumetric change than BCR and BIO in all immersion solutions (P<0.05). BIO and BCR presented similar volumetric changes when immersed in PBS and distilled water (P>0.05). When the in vivo method was used, BIO and BCR showed lower volumetric change (P<0.05), including an increase in volume for BCR. The immersion solutions influenced the evaluation of the volumetric change of bioceramic repair materials. Bioceramic materials show greater volumetric stability when evaluated by the in vivo method. The in vivo method in the subcutaneous tissue of rats can be an alternative for analyzing the properties of bioceramic cement, showing similarity with the clinical application.

Abstract Investigate individual and contextual determinants associated with bullying in schoolchildren eight to ten years of age. A cross-sectional study was conducted with 739 schoolchildren, who answered a question about episodes of bullying related to oral health and questionnaires addressing childhood anxiety and orofacial dysfunction. The guardians provided information on sociodemographic characteristics, sleep disorders, and oral health literacy. Trained examiners assessed the children for the diagnosis of dental caries using the International Caries Detection and Assessment System, malocclusion using the Dental Aesthetic Index, orofacial dysfunction using the Nordic Orofacial Test-Screening and traumatic dental injury (Andreasen criteria) (Kappa> 0.80). The contextual variables were the type of school and the monthly income of the school neighborhood. Descriptive statistics was performed to characterize the sample and unadjusted and adjusted (p <0.05) multilevel Poisson regression models were run. The prevalence of bullying was 13.3%. After the adjusted analysis, malocclusion (PR=1.59; 95%CI:1.03-2.44) and anxiety (PR=1.79; 95%CI:1.10-2.93) remained associated with bullying. In terms of context, the monthly income of the neighborhood of the school was associated with bullying (PR=1.75; 95%CI:1.12-2.72). Malocclusion and anxiety influenced the occurrence of bullying. A lower average income in the school neighborhood was an important contextual determinant for the increase in the prevalence of bullying.

ABSTRACT The umbu-cajazeira (Spondias sp.) is a fruit tree native to the semi-arid of Brazil, with significant environmental and agro-socioeconomic potential for the region. Determining leaflet area (LA) is essential for understanding the interactions between plant growth, physiology, nutrition, and environment. Thus, this research aims to construct allometric equations that non-destructively estimate the umbu-cajazeira (Spondias sp.) leaflet area, considering the leaflet dimensions (length and width). The leaflets were collected from mother plants of umbu-cajazeira (Spondias sp.) and individually measured for length (L), width (W), and LA using digitized images. These data were submitted for descriptive and regression analysis. The LA was estimated using, linear power, and exponential regression models based on the L and W of the leaflets. The best model and equation were chosen based on the following selection criteria: coefficient of determination, Willmott agreement index, root mean square error, and mean absolute error. The power model using LW presented the best equation ŷ = 0.76 * LW0.98 to estimate the leaflet area of umbu-cajazeira (Spondias sp.). This study provides a reliable, accurate, fast, and non-destructive approach for agronomic researchers and growers to determine the LA of the species.
A assistência à saúde no governo militar (1964-1985) e sua herança para o SUS: o híbrido público-privado
Authors: Menicucci Telma
Published: September 2024

Resumo O artigo analisa a política de assistência à saúde desenvolvida durante o governo militar no Brasil (1964-1985), com foco principal na relação do setor público com o privado na produção de serviços de saúde, nas diversas modalidades em que isso ocorreu, e suas repercussões. O objetivo, a partir de uma perspectiva institucionalista e histórica, que considera os mecanismos por meio dos quais políticas prévias afetam o processo decisório posterior e colocam limites às possibilidades de mudanças, é identificar os efeitos dessa política na configuração da reforma da política de saúde, produzida no processo de democratização, que levou à criação de um sistema de saúde universal e integral. Entre esses, destacam-se os efeitos políticos na configuração da arena da saúde; efeitos cognitivos relativos à percepção da política de saúde, e efeitos na capacidade governamental de produção e regulação de serviços. O resultado foi a manutenção de uma dualidade do sistema de saúde, garantindo a convivência de um setor privado vigoroso com um sistema público pretensamente universal e que colocou/coloca dificuldades ao SUS, mas não impediu sua implantação e institucionalização. O artigo é extraído de livro publicado anteriormente.

Resumo A atenção primária à saúde é a principal porta de entrada e prioridade na gestão de saúde no Brasil. Contudo, existem desafios importantes na qualidade da atenção, em particular aos mais vulneráveis, especificamente na rede de saúde materna-infantil (RASMI). Esse fato é agravado pelas já conhecidas desigualdades regionais, que historicamente afetam mais as regiões Norte e Nordeste. O objetivo é avaliar no espaço-tempo a estrutura da RASMI em Roraima, na região Norte e no Brasil nos anos de 2012, 2014 e 2017. Para isso, a fonte de dados será o Programa Nacional de Melhoria do Acesso e Qualidade da Atenção Básica (PMAQ-AB), Módulo I. Observou-se melhoria significativa nos indicadores de infraestrutura física, como ambiência/climatização; e na distribuição de insumos/equipamentos necessários à assistência materno-infantil, percebeu-se um crescimento progressivo entre 2014 e 2017. Por outro lado, notou-se piora na disponibilidade de medicamentos e diminuição de quantidade/carga-horária de recursos humanos. O estudo configurou uma importante análise longitudinal, comparativa entre a realidade estadual e nacional, que contribui para a formulação de políticas e programas relativos aos direitos reprodutivos e à assistência materno-infantil.

Abstract The article aims to identify stage of the food supply chain (FSC) has the greatest food loss and waste (FLW), the factors that influence and economic, social and environmental impacts in Latin America countries. We carried out a scoping review of observational studies, case reports and interventional studies in January 2023. Searches were performed in scientific databases and hand-searching of reference lists. Data on the included studies were summarized with narrative synthesis. In total 16 articles met the inclusion criteria. The greatest FLW occur in the early and middle stages of the FSC, mainly during storage. The main causes were connected to financial, managerial and operational limitations related in harvesting techniques, storage and cooling facilities, infrastructure and marketing systems. Food waste (FW) is also a result of lack of appropriate storage facilities and efficient transport systems, market fluctuations and systems. Only one study presented results on the environmental impact of FW. There is a higher occurrence of food loss, characterized by decrease in the quantity and quality of food in the first three stages of FSC.

Resumo O objetivo do artigo é avaliar o efeito da pandemia de COVID-19 sobre a má nutrição em crianças menores de dois anos inscritas no Programa Bolsa Família. Estudo ecológico de série temporal interrompida, tendo o baixo peso por idade, o déficit de estatura e o excesso de peso como variáveis tempo-dependentes de má nutrição, extraídas mensalmente (jan/2008 a junho/2021) do Sistema de Vigilância Alimentar e Nutricional. A pandemia de COVID-19 foi a exposição, dicotomizada em pré e pandemia. No programa RStudio, a tendência foi obtida pela regressão de Prais-Winsten, e o efeito da pandemia sobre as variáveis tempo-dependentes, pela modelagem SARIMA, calculando-se coeficientes de regressão (CR) ajustados para tendência prévia e sazonalidade (α = 5%). A pandemia se associou ao aumento do: i) baixo peso por idade no Sul (CR = 0,94; p < 0,001) e Sudeste (CR = 1,97; p < 0,001); ii) déficit de estatura no Centro-Oeste (CR = 2,4; p = 0,01), Sul (CR = 2,15; p < 0,001) e Sudeste (CR = 2,96; p < 0,001); e iii) excesso de peso no Norte (CR = 1,51; p=0,04), Centro-Oeste (CR = 2,29; p = 0,01), Sul (CR = 2,83; p < 0,001) e Sudeste (CR = 0,72; p = 0,04). A pandemia aumentou o baixo peso no Sul e Sudeste e a dupla carga de má nutrição no Centro-Oeste, no Sul e no Sudeste. No Nordeste e no Norte persistem taxas mais altas de má nutrição.
