Objectives

A connection between thyroid hormones (THs) and diverse metabolic pathways has been reported. We evaluated thyroid function and tissue sensitivity to THs in children and adolescents with T1D in comparison to euthyroid controls. Additionally, we investigate whether a relationship exists between sensitivity indices and metabolic parameters.

Methods

A retrospective analysis was conducted on 80 pediatric patients diagnosed with T1D. Clinical parameters, TSH, FT3, FT4, and the presence of MS were documented. Additionally, indices of peripheral sensitivity (FT3/FT4 ratio) and central sensitivity (TSH index, TSHI; TSH T4 resistance index, TT4RI; TSH T3 resistance index, TT3RI) were assessed. Thirty healthy subjects were considered as controls.

Results

The overall prevalence of MS was 7.27 %, with MS identified in 8 out of 80 (10 %) T1D subjects; none of the controls manifested MS (p<0.01). No significant differences were observed in indexes of tissue sensitivity to THs between subjects with or without MS (all p>0.05). Correlations between THs and indexes of THs tissue sensitivity and metabolic parameters in controls and T1D patients were noted.

Conclusions

This study affirms a heightened prevalence of MS in children with T1D compared to controls and underscores the potential role of THs in maintaining metabolic equilibrium.

Antibacterial effect of novel dental resin composites containing rod-like zinc oxide
Authors: Zhou Shiyu , Liu Ruihua , Ma Xinru , Xie Yushi , Xu Xiaoling , Du Qin , Zhou Zuowan
Published: March 2024

Dental resin composite materials are widely used as dental fillings; however, the accumulation of microbes and the resulting secondary caries often leads to filling failure. ZnO, an inorganic antibacterial material, exhibits effective antibacterial properties and is considered safe for use. In this study, rod-like ZnO was prepared by using the atmospheric-pressure hydrothermal method, and its microstructure and antibacterial effects on Streptococcus mutans were studied. Subsequently, we created modified resins by incorporating rod-like ZnO at varying mass fractions and analyzed their morphological characteristics and elemental distributions. The antibacterial effectiveness, biocompatibility, and mechanical properties of these materials were examined using in vitro experiments. The results indicated that the rod-like ZnO exhibited a complete hexagonal wurtzite structure, with columnar dimensions of approximately 2.5 μm in length, 0.8 μm in diameter, and a lattice spacing of 0.2544 nm. The growth, biofilm formation, and biofilm destruction of S. mutans were significantly inhibited at 1/4, 1/2, 3/4, and 1 times the minimum inhibitory concentration. The rod-like modified resin, with mass fractions of 2.5, 5, and 7.5 wt%, exhibited evident inhibitory effects on S. mutans biofilm formation. These modified resins demonstrated no cytotoxicity toward HGF-1 cells and exhibited enhanced compressive strength. Therefore, rod-like ZnO modified resin has promising potential for the treatment of dental caries.
Japanese politeness revisited: from the perspective of attentiveness on Twitter
Authors: Fukushima Saeko
Published: March 2024

Previous research has shown that attentiveness (kikubari) is a significant aspect of politeness in Japanese. The aim of this paper is to expand on earlier research on attentiveness by using Twitter data and examine how Japanese lay people understand and/or evaluate attentiveness and how attentiveness manifests politeness. The data for this study were 600 Japanese tweets which contain attentiveness. They were coded based on analysis of the content and analysed both quantitatively and qualitatively. The results show that Japanese lay people evaluate attentiveness positively and that they think attentiveness is important in most cases. These results reflect a commonly held belief in Japanese culture, namely that attentiveness is a virtue. In some posts, the demonstrators of attentiveness appeared to infer the needs of the potential recipients and made pre-emptive offers, as they had known the situations of the potential recipients. Attentiveness in such posts coincides with the definition of attentiveness in previous research. In some other posts, attentiveness is used in the sense of consideration, which was included in the conceptualisation of politeness in Japanese. These results confirmed earlier findings and further our understanding of them through concrete examples from Twitter.
Intracerebral dynamics of sleep arousals: a combined scalp-intracranial EEG study

Published: March 2024

As an intrinsic component of sleep architecture, sleep arousals represent an intermediate state between sleep and wakefulness and play an important role in sleep-wake regulation. They have been defined in an all-or-none manner, whereas they actually present a wide range of scalp-electroencephalography (EEG) activity patterns. It is poorly understood how these arousals differ in their mechanisms. Stereo-EEG (SEEG) provides the unique opportunity to record intracranial activities in superficial and deep structures in humans. Using combined polysomnography and SEEG, we quantitatively categorized arousals in non-rapid eye movement sleep into slow wave (SW) and Non-SW arousals based on whether they co-occurred with a scalp-EEG SW event. We then investigated their intracranial correlates in up to 26 brain regions from 26 patients (12 females). Across both arousal types, intracranial theta, alpha, sigma, and beta activities increased in up to 25 regions (p<0.05,d=0.06-0.63), while gamma and high frequency (HF) activities decreased in up to 18 regions across five brain lobes (p<0.05,d=0.06-0.44). Intracranial delta power widely increased across five lobes during SW arousals (p<0.05 in 22 regions,d=0.10-0.39), while it widely decreased during Non-SW arousals (p<0.05 in 19 regions,d=0.10-0.30). Despite these main patterns, unique activity was observed locally in some regions such as the hippocampus and middle cingulate cortex, indicating spatial heterogeneity of arousal responses. Our results suggest that Non-SW arousals correspond to a higher level of brain activation than SW arousals. The decrease in HF activities could potentially explain the absence of awareness and recollection during arousals.

Significance StatementIntrinsic to sleep architecture, sleep arousals play an important role in sleep-wake regulation. They are defined in an all-or-none manner, whereas they actually present various scalp electroencephalography (EEG) patterns. Using simultaneous scalp and intracranial EEG in humans, we analyzed the intracranial activity during two types of arousals marked on scalp EEG, quantitatively categorized by whether they co-occurred with a scalp-EEG slow wave (SW). Non-SW arousals present prevalent low-voltage fast activity, while SW arousals exhibit high-voltage slow waves alongside fast activities. This work represents the first intracranial study of different types of NREM sleep arousals and provides a comprehensive description of local brain activities during both arousal types, serving as a foundation for future studies investigating regional behaviors during sleep-wake transition.
Pan-Arctic analysis of the frequency of under-ice and marginal ice zone phytoplankton blooms, 2003–2021
Authors: Payne Courtney M. , van Dijken Gert L. , Arrigo Kevin R.
Published: March 2024

Under-ice (UI) phytoplankton blooms have been observed in most of the marginal seas of the Arctic Ocean and are often found to contribute substantially to total primary production. However, because remote sensing studies cannot directly measure UI blooms and limited in situ observations prevent analysis of their frequency across the region as a whole, their distribution has not been characterized across the Arctic Ocean. Here, we use remote sensing data to discern which parts of the seasonally ice-free Arctic Ocean demonstrate evidence of UI blooms and whether UI bloom frequency changed between 2003 and 2021. Results suggest that UI blooms were generated frequently, with evidence of UI blooms over nearly 40% of the observable seasonally ice-free Arctic Ocean, while marginal ice zone blooms covered 60% in any given year. However, while there was no significant change in the UI bloom area over the study period, there was a 7% decline in the proportion of UI area in the seasonal sea ice zone. This decline was driven largely by declines at lower latitudes, where sea ice retreats earlier in the year, and in the Chukchi Sea, where UI blooms were also most prevalent. Our analysis demonstrates the need for increased observational studies of UI blooms and their ecological and biogeochemical consequences throughout the Arctic Ocean.

Published: March 2024

In brief

HSP90AA1 is a ubiquitous molecular chaperone that can resist cellular stress, such as oxidative stress and apoptosis, and mediate the efficacy and protein folding of normal cells during heat stress, as well as many other functions. This study further reveals the role of HSP90AA1 in bovine oocyte maturation and early embryonic development.

HSP90AA1, a highly abundant and ubiquitous molecular chaperone, plays important roles in various cellular processes including cell cycle control, cell survival, and hormone signaling pathways. In this study, we investigated the functions of HSP90AA1 in bovine oocyte and early embryo development. We found that HSP90AA1 was expressed at all stages of development, but was mainly located in the cytoplasm, with a small amount distributed in the nucleus. We then evaluated the effect of HSP90AA1 on the in vitro maturation of bovine oocytes using tanespimycin (17-AAG), a highly selective inhibitor of HSP90AA1. The results showed that inhibition of HSP90AA1 decreased nuclear and cytoplasmic maturation of oocytes, disrupted spindle assembly and chromosome distribution, significantly increased acetylation levels of α-tubulin in oocytes and affected epigenetic modifications (H3K27me3 and H3K27ac). In addition, H3K9me3 was increased at various stages during early embryo development. Finally, the impact of HSP90AA1 on early embryo development was explored. The results showed that inhibition of HSP90AA1 reduced the cleavage and blastocyst formation rates, while increasing the fragmentation rate and decreasing blastocyst quality. In conclusion, HSP90AA1 plays a crucial role in bovine oocyte maturation as well as early embryo development.

Numerical studies of the kinetics of steel desulfurization with pneumatic stirring
Authors: Timoshenko S.M. , Smirnov O.M. , Niemtsev E.M.
Published: March 2024

Analysis of recent research and publications. In the conditions of mini-mills, the removal of sulfur in a number of cases is the limiting link in the production of steel. The kinetics of desulfurization is determined by the specific stirring power of the steel melting bath. The influence of the geometry of the bath on the efficiency of pneumatic mixing and desulfurization of steel at a fixed mass has not been sufficiently studied. Purpose and method. The purpose of the work is increasing the energy efficiency of steel production in the conditions of a mini-mill due to the minimization of steel desulfurization time. The method consists of numerical modeling of the desulfurization kinetics taking into account the geometric parameters of the steel melting bath and regime parameters of pneumatic mixing. Novelty and scientific significance of research. In the context of the kinetics of steel desulphurization, an understanding of the energy component of the process was developed through the specific power of pneumatic mixing of the liquid bath Nmix. The finiteness of the isothermal expansion model of the rising gas bubble for determining Nmix in industrial conditions through argon flow rate is shown. A mathematical model for estimating Nmix when purging the bath with argon in jet-bubble mode through the averaged speed of liquid steel movement and Archimedes’ force as a function of the gas content ratio in the two-phase region is proposed. The model allows optimizing argon flow rate according to the criterion of the maximum specific power of pneumatic mixing. This mode ensures the minimum duration of steel desulfurization for the given slag parameters and geometry of the steel melting bath-bottom porous plug system. Practical value. Determining the optimal flow rate of argon to ensure the maximum specific power of pneumatic mixing of a steel melting bath of a certain geometry and mass in the context of minimizing the duration of desulfurization contributes to increasing the energy efficiency of the steel production technology in the conditions of mini-mill operation.

Published: March 2024

Left atrial appendage occlusion (LAAO) is a suitable alternative to oral anticoagulant therapy to prevent stroke in patients with AF. Most procedures are performed under transoesophageal echocardiography (TOE) guidance, which facilitates transseptal puncture, reduces the risk of procedure-related complications and provides an additional method for device selection and real-time monitoring during device deployment. However, TOE has significant shortcomings, including the need for general anaesthesia/deep sedation as well as a significant risk of procedure-related adverse events. More recently, intracardiac echocardiography has been proposed as an alternative to TOE guidance during LAAO procedures. In this review, we summarise the available evidence as well as providing a step-by-step approach for intracardiac echocardiography-guided LAAO.

Britain has a long history of enjoying food in the open-air, and one of the ways eighteenth century Londoners could enjoy both, was in the numerous pleasure gardens of the time. The largest, Ranelagh and Vauxhall Gardens, covered many acres in or near the city and boasted numerous well-lit walks and discrete alcoves. However, for a brief forty years in the middle of the century, Marybone Gardens, a small attraction in the rural fields to the north-west of the city, managed to compete with them on an almost equal level. This was due to the vision of one family to, unlike the other venues, serve tasteful and elegant food and drinks in peaceful and refined surroundings. This enterprise would create Britain’s first celebrity baker, the subject of this paper, whose career and creations can be traced, almost exclusively, through the newspaper advertisements of the day.
The Post-pandemic Consumer: Evidence from Empirical Research of Four Generations of Consumers
Authors: Maciejewski Grzegorz
Published: March 2024

Objective: The article analyses the changes in Polish consumer behaviour during the pandemic caused by the SARS CoV-2 virus. Changes in behaviour identified in 2022 were also analysed through the crisis caused by the war in Ukraine.
Research Design & Methods: Literature studies and original empirical research were conducted. The empirical research – an online survey using the Ariadna National Research Panel – was carried out in two waves, the first in November 2020 on a sample of N = 1,045 consumers and the second in November 2022 on a sample of N = 1,100 consumers. The online survey technique made it possible to reach adult consumers from all regions of Poland.
Findings: The research findings confirmed that consumer behaviour changed during the pandemic. Above all, consumers did more things remotely. They also took better care of their health and hygiene, and used payment cards more often than they had. Going out to cultural institutions and using the services of catering establishments were subject to the most radical restrictions. Respondents were mainly unsure of whether the two crises increased their household spending.
Implications / Recommendations: Compared to 2020, in 2022 the percentage of consumers undertaking various types of preventive and prudent behaviours due to the pandemic decreased. This may indicate a desire among consumers to return to the lifestyle and behaviours they led before the pandemic. Consumers seem to be slowly forgetting about the pandemic, absorbed by another real threat: the war in Ukraine.
Contribution: The conducted research contributes to the development of the theory of consumer behaviour. It shows changes in the behaviours of these entities caused by the pandemic situation, which they have not experienced so far. It complements the research on the behaviour differentiation of individual generations of consumers (Z, Y, X, and BB).
Perceived Brand Globalness and Localness: A Bibliometric Analysis
Authors: Jadach Robert , Pluta-Olearnik Mirosława
Published: March 2024

Objective: The purpose of the article is to establish the current state of research on the perceived brand globalness / localness (PBG / PBL) dichotomy. It analyses and assesses the changes in the research problems and identifies the areas upon which PBG / PBL research is currently focused.
Research Design & Methods: The research method used in the article is bibliometric analysis, supplemented by content analysis of literature selected from the Scopus database. A four-step procedure was used to collect data and conduct bibliometric analyses: stage 1 – searching and identifying primary literature, stage 2 – review of the literature (screening), stage 3 – data export, stage 4 – bibliometric analysis supplemented by a content analysis of the literature. In addition, a co-occurrence analysis of keywords was carried out using VOSviewer.
Findings: The research on PBG / PBL issues is concentrated in five main areas: 1) brand value signaling, 2) PBG / PBL interaction, 3) PBG impact on purchase intentions, 4) PBL impact on purchase intentions, and 5) the effect of country of origin/consumer ethnocentrism on consumer preference for foreign (global) vs. domestic (local) brands. The study also examines changing trends in PBG / PBL research.
Implications / Recommendations: Recent world events including the COVID-19 pandemic, the Russian invasion of Ukraine and trade wars have slowed globalisation. Since buying behaviour is visibly changing under the influence of socio-economic factors, there is a need for further research to verify consumer preferences vis-à-vis global / local brand positioning.
Contribution: The review and analyses performed enrich the existing literature on PBG / PBL, while the findings presented can serve as a starting point for further research.
The Use of Technological Bricks in Agile: Conclusions Based on Analysis of the Literature and on Empirical Research
Authors: Zakrzewska Małgorzata , Jarosz Szymon , Kosała Małgorzata , Sołtysik Mariusz
Published: March 2024

Objective: The main objective of the study was to assess the level of Agile implementation in organisations in Poland and to determine the most commonly used Agile methods. The intention of this paper is to present the results of empirical research on technological tools supporting agile organisations in Poland and consider which digital competencies may favour their use.
Research Design & Methods: This paper presents a review of the literature and the results of empirical research on the use of information technology in enterprises which follow Agile practices and approaches. Empirical research is based on an interview questionnaire, which contained questions about the level of Agile implementation in the organisation, Agile implementation and support areas, support factors, barriers to implementation, and implementation results.
Findings: The paper presents the main IT tools used in agile enterprises and the results of research conducted in this field. The study shows that in 2019 companies mainly used the Agile approach for the creation of innovative services and (or) products. Research also indicates that, when it comes to Agile Good Practices, respondents most often use Scrum and Kanban. Practices such as DevOps, TDD, or SAFe were much less frequently used by the companies surveyed.
Implications / Recommendations: The results of the research provide valuable information on three issues: implementation of the Agile approach in Polish enterprises, assessment of the use of technological bricks in Polish enterprises, and an analysis of good practices in Polish enterprises. The research also indicates directions for further research. Among others, it is recommended to repeat the research on the level of agility of the organisation in Poland, primarily to check whether the level of implementation has changed and whether the implementation has taken place in other key areas of the company.
Contribution: Literature review and economic practice indicate that there is increasing popularity of the use of information technologies, not only in agile organisations but in general, requiring employees and managers to improve their digital competencies. This paper addresses the need to evaluate the current state of Agile implementation in the organisation and examines the use of technological bricks in Agile in both theoretical and empirical ways.

Published: March 2024

The study was conducted as part of a current task of studying factors in the development of an organization's human capital that have a direct or indirect impact on employee productivity. The set of such factors includes indicators of the level of development of competencies and the degree of burnout of the individual. The work aims to develop economic and mathematical tools that would quantitatively describe the impact of employee competency values on their key performance indicators (KPIs), taking into account the level of burnout determined by the values of loyalty, involvement, and satisfaction. To achieve this goal, a hypothesis is put forward about the possibility of constructing a tool that makes it possible, based on a fuzzy classification of employees by level of competency development, to construct functional dependencies of KPIs on burnout indicators for each category. The initial data used were the results of a self-assessment of competencies and burnout of employees, mainly working in the areas of IT and HR in seven large Russian companies, calibrated by the immediate supervisors of the respondents, and the actual values of their KPIs. The work proposes an approach that includes two stages. As the first step, a fuzzy model is built that makes it possible, based on a weighted integral indicator of competency development with optimal weighting coefficients, to divide the range of values of the integral indicator into categories of uneven size, with the help of which it is possible to predict the achievement of KPIs. As the second step, an econometric model of the dependence of KPI on employee burnout indicators was built using the weighted least squares method to explain the dispersion of KPI values of employees belonging to individual competency categories in a fuzzy formulation, around the expected KPI value. The proposed tool will make it possible to predict the achievement of KPIs by employees depending on the input values of competencies and the level of burnout. In the future, this will make it possible to form an optimal portfolio of well-being program activities that will influence the development of employee competencies and reduce their level of burnout, and, therefore, contribute to the maximum progress in achieving target KPI values.

RESUMO O presente artigo insere-se no domínio da teoria do direito, tendo por objetivo discutir o conceito e a centralidade da autoridade no debate contemporâneo em torno do positivismo jurídico, bem como oferecer uma posição alternativa, sustentada por Pachukanis e baseada no sujeito de direito (uma categoria quase que esquecida, ofuscada pelo horizonte da norma jurídica e de sua autoridade). O estudo procede com uma análise comparativa da noção de autoridade nos autores clássicos do positivismo jurídico (Austin, Kelsen e Hart), indicando como essa perspectiva ainda é hegemônica no pensamento jurídico contemporâneo, mesmo nas versões contemporâneas do juspositivismo. O passo seguinte é o contraste das concepções baseadas na autoridade com a concepção de Evgeni Pachukanis, cujo cerne é a subjetividade jurídica. Ao se comparar as principais propostas teóricas com a perspectiva pachukaniana da forma jurídica, nota-se que a autoridade é um conceito vazio, incapaz de definir a especificidade histórica do direito. Compreendida como poder repressivo do Estado, como poder socialmente reconhecido ou como razão legítima (autoproclamada) para agir, a autoridade não pode fornecer as fronteiras conceituais do fenômeno jurídico.
HOW THE PRINCIPLE OF SUFFICIENT REASON UNDERMINES THE COSMOLOGICAL ARGUMENT
Authors: Briceño Sebastián
Published: March 2024

ABSTRACT My aim here is to show how the Cosmological Argument (CA) is undermined by one of its own premises: the Principle of Sufficient Reason (PSR). Firstly, I explain the type of CA that I am thinking about (I). Secondly, I explain a traditional modal objection against the PSR, which is ultimately based upon our intuitions in favor of contingency (II). Thirdly, I show how this modal objection begs the question against the necessitarian, and then I reformulate the CA in more neutral terms (III). Fourthly, using this more neutral version of the CA, I argue that the main problem with the PSR goes way beyond its apparent necessitarian consequences. As an argument used by Bradley shows, embracing the rationalist path that underlies the PSR seems to commit us to a form of Radical Monism too (IV). Finally, I conclude by showing how this result ultimately undermines the CA itself (V).
É POSSÍVEL OUVIR O TEMPO-DURÉE? UMA CRÍTICA AO BERGSONISMO MUSICAL
Authors: Nachmanowicz Ricardo
Published: March 2024

RESUMO O artigo analisa o tema da escuta musical do tempo na filosofia de Vladimir Jankélévitch, buscando avaliar qual seja a prova fenomênica alegada por Jankélévitch para sustentar a tese de que a escuta musical do tempo carrega as mesmas propriedades do conceito de durée de Henri Bergson. Concluímos que (1) as descrições temporais de Jankélévitch não são suficientes para sustentar que a escuta musical equivale à escuta das propriedades da durée, e que (2) esse fato implica um problema tanto para a máxima “a música é a arte do tempo” quanto para a capacidade geral do bergsonismo, verificado em demais autores, em fundar uma filosofia da música.
HEGEL Y LA MUERTE: REFLEXIONES DESDE HEIDEGGER, KOJÈVE Y BATAILLE
Authors: Cernadas Gonzalo Ricci , Natale Nicolás Di
Published: March 2024

RESUMEN En este artículo proponemos estudiar la manera en que la conceptualización de la muerte llevada a cabo por Hegel ha sido leída por una serie de autores. De esta manera, en un primer apartado restituiremos la interpretación realizada por Heidegger sobre Hegel, para, en un segundo momento, recuperar la lectura decisiva de Kojève sobre el mismo autor, y terminar con una reposición de la hermenéutica llevada a cabo por Bataille del filósofo idealista alemán. Así, se expondrá en la conclusión al presente artículo la existencia de motivos repetidos y sumamente similares presentes en los tres pensadores recién nombrados, para quienes ciertamente la figura de Hegel ha constituido una herencia insoslayable.

Abstract: Disasters cause changes in morbidity, mortality, and medicine use. Brazil is one of the main producers of mineral ores at great environmental cost. Mine tailings are stored in dams and ruptures have led to major disasters. We investigated the consumption of psychoactive medicines in the municipalities affected by the Fundão dam disaster in Minas Gerais State. An ecological study was carried out on drug consumption, estimated using public purchases in Minas Gerais and dispensing data from private retail pharmacies. Consumption (in number of defined daily doses/100,000 inhabitants per day) was analyzed descriptively in eight municipalities, stratified according to consumption level during a 25-month period. Six comparisons of mean consumption values for both data sets were done for pre- and post-disaster periods. The means of medicine consumption before and after the event were plotted and linear trends were added. Public purchase data evinced high consumption levels. Only pharmaceutical retail showed significant differences between the strata in the pre-disaster versus two post-disaster periods. Smaller municipalities showed an increase in consumption 15 months after the disaster. Clonazepam led the way in pharmaceutical retail consumption, followed by fluoxetine. Medicines showed an upward trend after the disaster. The high public provision may have stifled significant consumption patterns of psychoactive drugs; however, peak consumption were observed in private retail, suggesting a modification in use patterns after the disaster. The decrease in consumption immediately after the event was probably related to lower care-seeking behavior on the part of the population, and significant peaks after the disaster may reflect economic consequences of it.

Published: March 2024

Resumo: Este artigo apresenta os resultados de uma pesquisa sobre a percepção dos profissionais de saúde sobre a hesitação vacinal infantil relacionada à COVID-19. Baseado no constructo teórico da hesitação vacinal, foi realizada uma pesquisa qualitativa com 86 trabalhadores da atenção primária à saúde (APS) em quatro municípios de quatro estados brasileiros e no Distrito Federal. A análise temática foi realizada e obtiveram-se três categorias: medo, desinformação em vacina e papel dos profissionais de saúde. O medo como motivo de hesitação vacinal gerou reflexões sobre a condução da pandemia pelo Governo Federal, principalmente no que tange à governabilidade por meio desse afeto, e sobre as consequências do uso das plataformas digitais na população. O medo relacionou-se ao fato de a vacina ainda ser percebida como experimental; às possíveis reações adversas; à ausência de estudos de longo prazo; à falsa percepção de risco reduzido da COVID-19 em crianças; e às condutas do Governo Federal geradoras de insegurança nos efeitos da vacina. A desinformação em vacina relacionou-se às fake news sobre a vacina e suas reações; ao fenômeno da infodemia e desinformação; e à ausência de orientação e conhecimento sobre vacinas. Por fim, o trabalho discute o papel fundamental dos profissionais de saúde da APS no aumento da cobertura vacinal devido à confiabilidade perante a população e à proximidade com os territórios, fatores que possibilitam reverter o medo e a desinformação diante das vacinas. Ao longo do trabalho, buscou-se apresentar as convergências entre o conteúdo dos temas delineados e os determinantes da hesitação vacinal e refletir sobre possibilidades para a reconstrução da alta adesão às vacinas infantis.

Published: March 2024

Resumo O presente artigo visa avaliar os fatores que estão associados ao consumo de bens e serviços culturais diretos fora do domicílio, considerando tal consumo como interligado ao consumo de outros bens e serviços culturais. A metodologia empregada engloba a aplicação de um modelo probit bivariado. Para tanto, são utilizados os dados da Pesquisa de Orçamentos Familiares (POF) de 2017-2018. No geral, os resultados obtidos para o modelo indicam que o consumo de bens e serviços culturais diretos fora do domicílio e o consumo de outros bens e serviços culturais são positivamente correlacionados, destacando a questão da desigualdade no consumo cultural devido a certas barreiras sociais (educação, renda, acesso a crédito, entre outros).

ABSTRACT Species of the genus Capsicum, especially peppers, are economically important and widely consumed worldwide. The application of animal waste as organic fertilizer is a simple and cost-effective technique for applying nutrients to the soil. Combining cattle manure with humic substances can stimulate plant metabolism, resulting in increased nutrient absorption and assimilation. Therefore, the objective in this study was to evaluate doses of cattle manure combined with humic substances for stimulating plant metabolism and morphophysiological and nutritional processes in pepper plants. A randomized block design with four replicates was used, in a 4×3 factorial arrangement consisting of four cattle manure doses (8, 18, 28, and 38 Mg ha-1) and three humic substance doses (0, 8, and 12 kg ha-1). Humic substances (12 kg ha-1) enhanced gas exchange, increasing net photosynthesis (34.2%), stomatal conductance (12.7%), instantaneous water use efficiency (15.87%), instantaneous carboxylation efficiency (37.37%), and absorbed energy conversion efficiency (23.53%). Cattle manure adequately met the crop’s nutritional requirements, while humic substances increased the number and thickness of plant root hairs. The most effective combination to increase photosynthetic activity in pepper plants was 38 Mg ha-1 of cattle manure combined with 8 kg ha-1 of humic substances. Humic substances stimulated positive morphophysiological responses in organic pepper crops, which resulted in increased production.

ABSTRACT The application of biostimulants in agriculture has been studied to increase production while using smaller physical spaces and agricultural inputs to increase sustainability in production systems. Despite the promising results, there is a need to study the effects of joint applications of these products, identifying possible interactions during crop development. Thus, this study aimed to verify the biostimulant potential of the isolated and combined use of nicotinamide and Azospirillum brasilense during the initial growth of pumpkin plants in hydroponic cultivation. A completely randomized design with six treatments and four replicates was performed. The treatments were composed by the combination of the application of nicotinamide (foliar) and A. brasilense (foliar or applied in the hydroponic solution). Treatments increased the gas exchanges, particularly the assimilation rate and carboxylation efficiency, being superior to the control treatment. However, for growth characteristics, the isolated application of nicotinamide favored the development of the shoot and, when combined with A. brasilense via foliar, increased root growth. Thus, the application of nicotinamide and A. brasilense alone or together enhances the growth and gas exchanges of pumpkin plants grown in a hydroponic system, especially when using foliar application of A. brasilense. Whereby its action can be referred to as a biostimulant effect. Furthermore, the application method affects the efficiency and compatibility of the products applied. Therefore, foliar application is recommended.
