Objective

The European Registries for Rare Endocrine Conditions (EuRRECa, eurreb.eu) includes an e-reporting registry (e-REC) used to perform surveillance of conditions within the European Reference Network (ERN) for rare endocrine conditions (Endo-ERN). The aim of this study was to report the experience of e-REC over the 3.5 years since its launch in 2018.

Methods

Electronic reporting capturing new encounters of Endo-ERN conditions was performed monthly through a bespoke platform by clinicians registered to participate in e-REC from July 2018 to December 2021.

Results

The number of centres reporting on e-REC increased to a total of 61 centres from 22 countries. A median of 29 (range 11, 45) paediatric and 32 (14, 51) adult centres had reported cases monthly. A total of 9715 and 4243 new cases were reported in adults (age ≥18 years) and children, respectively. In children, sex development conditions comprised 40% of all reported conditions and transgender cases were most frequently reported, comprising 58% of sex development conditions. The median number of sex development cases reported per centre per month was 0.6 (0, 38). Amongst adults, pituitary conditions comprised 44% of reported conditions and pituitary adenomas (69% of cases) were most commonly reported. The median number of pituitary cases reported per centre per month was 4 (0.4, 33).

Conclusions

e-REC has gained increasing acceptability over the last 3.5 years for capturing brief information on new encounters of rare conditions and shows wide variations in the rate of presentation of these conditions to centres within a reference network.

Significance statement

Endocrinology includes a very wide range of rare conditions and their occurrence is often difficult to measure. By using an electronic platform that allowed monthly reporting of new clinical encounters of several rare endocrine conditions within a defined network that consisted of several reference centres in Europe, the EuRRECa project shows that a programme of e-surveillance is feasible and acceptable. The data that have been collected by the e-reporting of rare endocrine conditions (e-REC) can allow the continuous monitoring of rare conditions and may be used for clinical benchmarking, designing new studies or recruiting to clinical trials.
FLAVOR Enhancers in Food Processing: Spectrophotometric Determination of Maltol and Ethyl Maltol in Some Commercial Food Samples During Different Storage Conditions
Authors: Hamza Srwa Ramadhan
Published: October 2023

It is important for flavor additives to maintain adequate thermal stability under high temperature conditions. Since many excellent fragrances are organic and have relatively small molecular weights, they lack thermal stability. As a result, a rapid and accurate method has been developed for simultaneous determination of maltol and ethyl maltol by reaction with iron(III) in sulfuric acid solution. This reaction was the basis for an indirect spectrophotometric method, which followed the development of the pink ferroin product (?max = 520 nm). It appears that ethyl maltol and maltol follow Beer's law at concentrations of 0.5–20.0 mg/L according to the optimized method. According to the alternative standard method, the LOD values for maltol and ethyl maltol are 0.2 mg/L and 0.3 mg/L, respectively. Commercial food samples were successfully analyzed using the proposed methods. A study was conducted to determine how different storage conditions affected the concentrations of maltol and ethyl maltol. High temperature and sunlight lead to decomposition of these two flavor enhancer concentrations more than 10%.

Published: October 2023

The dominant narrative is that public financing and investment in the public sector depend on the political leadership of the government executive because of the incentives gained in public finance management. The executive arm of the government includes elected political leaders and technocrats. Using the case of the agricultural sector, this paper examines the role of technocrats and elected leadership in investment choices. This paper uses, in support of quantitative findings, qualitative evidence from a case study designed in the Department of Animal Health and Livestock Development in Malawi. The variables were used to analyze the quantitative data, and content analysis was used for qualitative data. The finding reveals that seniority, authority, political affiliation, and technical expertise of civil servant leadership significantly influence public investment choices in the livestock sector in Malawi. Both elected political executives and technocrats had self-interests in delivering goods with swift and visible returns. The study concludes that Malawi's public sector investment arena is a ‘war zone’ with various actors vying for dominance. The paper recommends a critical review of the reforms in the livestock sector to bring the investment culture on course in Malawi. More studies are needed to resolve issues around privatization models of services in the livestock sector and the role of government and transactional actors.

Nowadays, rapid development and growth of the economic and social changed the ways of living in the community. For low-income people, they try to adjust themselves to survive in this changing world. One of the main problems for this group of people is lack of living places. A temporary shelter in a rural area as well as in an urban area is socially a direct solution in responding to their fundamental needs. Based on the study of temporary shelter in Khon Kaen, Thailand, the normal space within the shelter includes multipurpose area and sleeping area with size of 6 sq.m. for each area. This information is used for this study. The idea of the study is to make a low cost prefabricate temporary shelter. The process of the study began with transform the information from previous research to be a prototype one. An architectural drawing is made and discuss with local shop base on the requirement of using local materials, suitable for simple transportation, easy for construction and limited budget. The final prefabrication shelter has been built and installed for checking the problem of building. However, this study showed a few problems that have to be noted such as too many elements that need good organize process for example. Also, the study has found that the prefabricated shelter can be built to suit local need of Khon Kaen city and other parts of Thailand as well. Finally, this prototype can be applied for other function beside a shelter for living. It can be temporary site office, shop, or others.

Published: October 2023

The Lindley exponentiated Gumbel (LEGu) Distribution, a new family of probability distribution developed for modelling environmental data is introduced in this research paper. The investigation defines the new distribution's basic statistical properties, such as its shape, density function, hazard rate function, moment generation function, and maximum likelihood estimates of its model parameters. The study shows that, in comparison to other baseline distributions and comparators, increasing the number of parameters in the distribution improves its robustness and adaptability, making it more flexible in accommodating different types of data. The model is now more adaptable and can handle a wider range of data sets, making it a useful and effective tool for environmental modelling. The creation of the Lindley exponentiated Gumbel Distribution and the statistical qualities that go along with it bring up new possibilities for the analysis of environmental data, making a significant contribution to the larger initiatives in climate research and decision-making. The results of this study have the potential to advance our comprehension of environmental mechanisms and raise the precision of climate assessments and projections.

Published: October 2023

Aspergillus niger is a major mold-causing spoilage in cereals, fruits and vegetables. Controlling of mold in stored grains is essential for safety of food. Currently, application of microorganisms to control A. niger is a safer and more effective method. In this study, strain XZ30-2 against A. niger was isolated and identified as Bacillus cereus according to morphological and biochemical characteristics as well as 16 Svedberg ribosomal ribonucleic acid (16S rRNA) gene sequence analysis. The investigation of action mechanism showed XZ30-2 culture filtrate caused the mycelia inflated or contract, increasing the membrane permeability, leading to the intracellular leakage and nucleic acids release, disrupting the proton pump, decreasing the ergosterol content, inducing the membrane lipid peroxidation and reactive oxygen species (ROS) accumulation in A. niger. Moreover, B. cereus XZ30-2 culture filtrate could produce hydrolases and lipopeptides, including iturin, surfactin and fengycin. This work also evaluated the control effect of XZ30-2 on A. niger in wheat grains, and indicated that 40 μL/g of culture filtrate significantly controlled the infection of A. niger. Therefore, B. cereus XZ30-2 can be developed as a biological agent for controlling A. niger in stored grains.

Published: October 2023

Abstract The evaluation of new banana genotypes with agronomic potential and tolerant to the main pests and diseases is essential for the market. The objective was to evaluate the vegetative and productive characteristics of new potential banana clones, such as ‘Prata Gorutuba R1’ and ‘Prata Gorutuba R2’ and commercial cultivars. The experiment was implemented in a rural property located in the municipality of Nova Porteirinha, MG. The treatments consisted of ‘Prata Gorutuba R1’ and ‘Prata Gorutuba R2’ banana clones (genotypes selected from the ‘Prata Anã’ clone ‘Gorutuba’ tolerant to Panama disease) and four cultivars: ‘Prata Gorutuba’, ‘Prata Anã’, ‘Grande Naine’ and ‘BRS Princesa’. The treatments were distributed in randomized blocks, with four replications and six useful plants per plot. The planting spacing used was 3.5 m x 1.7 m. The evaluations were carried out in the first and second production cycles. The ‘Prata Gorutuba R1’ and’ Prata Gorutuba R2’ clones in general showed excellent performance compared to the already consolidated cultivars. The clones presented median height and number of leaves in the ideal flowering for banana trees of the ‘Prata’ subgroup. Bunch and bunch weight, as well as production were similar to the ‘Prata Anã’, ‘Prata Gorutuba’ and ‘BRS Princesa’ cultivars. Considering that the clones evaluated present high tolerance to Fusarium wilt, the result indicates that the materials have great potential for the registration of new cultivars.

Published: October 2023

ABSTRACT: Inclusion of rural youth is of great importance to facilitate nutritional security and make the food chain more sustainable. A positive attitude is necessary for active participation in agricultural activities. This case study was an attempt to check the attitude of rural youth regarding sustainable farming and its contributing factors. The study was carried out in the Punjab province of Pakistan and a transverse research design was used for this quantitative study. An interview schedule was used for getting the face-to-face response of rural youth. To make the unknown population of rural youth in Punjab, the Fisher formula was used and a sample of 413 was selected from purposely selected three districts of Punjab. After recording data, Statistical Package for Social Sciences (SPSS) was used to analyze the data. Descriptive Statistics was used to explain the response of rural youth for the decision on the base of data. Only 53 young farmers said that they have never been part of the formal education system and maximum number of farmers was close to 24 years of age or more than that. Rural youth of Punjab is lacking in non-formal education for acquiring or maintaining their skills & interests. Unemployment and having limited farm income are the biggest challenges that rural youth is facing. Rural youth show a strong inclination towards opting for sustainable farming alongside the availability of a supportive network. Regarding to learning capacities rural youth is lacking related to knowledge, communication means, novel approaches and in promoting sustainable farming initiatives. To achieve the goal of sustainability in changing environment, rural youth must have access to continuous training, communication sources, membership, or association with organizations with novel ideas covering all the changes happening in the farming business.

Published: October 2023

ABSTRACT The proper distribution of maize seeds in pneumatic dispensers is essential for high-quality sowing operations. To enhance seed distribution accuracy, advanced pneumatic mechanisms utilizing new electrically driven dosing devices have been developed, as mechanical mechanisms often lead to distribution errors. Consequently, it becomes imperative to assess the impact of these mechanisms, particularly concerning operational speed. This study aims to evaluate the transmission performance of pneumatic dispensers when depositing maize seeds at varying operating speeds. The experiment was conducted on a static simulation bench, employing a completely randomized design and assessing two seed distribution mechanisms at speeds of 5.0, 7.0, 9.0, 11.0, and 13.0 km h-1. Parameters analyzed included acceptable spacing, double failure, coefficient of variation, and precision index, gathered from five repetitions of 250 consecutive seed depositions. The results suggest that the independent electrically driven dosing mechanism outperforms the pneumatic dosing mechanism with mechanical transmission in terms of acceptable spacing (1.27), missing spacing (0.85), and accuracy index (1.31). However, it is crucial to note that an increase in operating speed negatively impacts seed quality for both dispenser drive mechanisms.

Published: October 2023

Abstract Fusarium oxysporum is the causal agent of Fusarium wilt in tomato plants. The most common form of control of this disease is through seed chemical treatment. However, the present work presents an alternative method, through the fumigation technique with essential oils. The pathogen F. oxysporum was inoculated on organic cherry tomato seeds through contact with sporulated Petri® plates. Thereafter, seeds were placed in stainless steel crucibles containing a 1.0 x 1.0 cm filter paper adhered to the lid and kept for 24 hours. This paper received 20 µL of each essential oil: tea tree, chia, citronella, lavender, anise basil, clove basil, and deionized water as control. This process was called “seed fumigation by essential oil”. After this process, a germination test was carried out in germ boxes with Germitest® paper to verify the variables Germination Speed Index (GSI), Germination (G%), and Mean time to germination (MGT). Mycelial growth was verified in Petri® plates containing PDA medium. The plates containing mycelial growth were observed through scanning electron microscopy to verify possible morphological damage in the hyphae of the pathogen. Tea tree essential oil was the one that allowed the greatest suppression of the phytopathogen. Therefore, new tests were carried out with this specific oil. In germ boxes, tests of germination (G%), Abnormal seedlings count (ASC), and percentage of seedlings with mycelial growth were carried out. In addition, plant elicitation tests were performed in tomato seedlings through the analysis of chitinase, glucanase, and total proteins. All tests were carried out in completely randomized designs with four replications. All data were submitted to the Lilliefors normality test, followed by the analysis of variance, and Tukey’s HSD (5% significance) for mean comparison. It was found that tea tree essential oil inhibited the mycelial growth of F. oxysporum without affecting the germination of cherry tomato seeds. Subsequent tests with this oil also demonstrated that there is a reduction in mycelia present in the seeds and a reduction in abnormal seedlings compared to the control. There was no significant difference between the variables tested for plant elicitation.

Abstract Trauma is a leading cause of death, permanent disability, and health care cost worldwide. The young and economically active are the most affected population. Exsanguination due to noncompressible torso hemorrhage is one of the most frequent causes of early death, posing a significant challenge to trauma and vascular surgeons. The possibility of limb loss due to vascular injuries must also be considered. In recent decades, the approach to vascular injuries has been significantly modified. Angiotomography has become the standard method for diagnosis, endovascular techniques are currently incorporated in treatment, and damage control, such as temporary shunts, is now the preferred approach for the patients sustaining physiological derangement. Despite the importance of this topic, few papers in the Brazilian literature have offered guidelines on vascular trauma. The Brazilian Society of Angiology and Vascular Surgery has developed Projetos Diretrizes (Guideline Projects), which includes this publication on vascular trauma. Since treating trauma patients is a multidisciplinary effort, the Brazilian Trauma Society (SBAIT) was invited to participate in this project. Members of both societies reviewed the literature on vascular trauma management and together wrote these guidelines on vascular injuries of neck, thorax, abdomen, and extremities.
A quarta onda feminista no Brasil

Published: October 2023

Resumo: A pesquisa aborda a quarta onda feminista no Brasil por meio de algumas estratégias. Primeiro foram destacadas suas características conforme autoras que dissertam sobre o tema. Posteriormente analisamos algumas dessas características (a presença no meio digital, a defesa de mais de uma pauta e a forma como estão se organizando) com base em dados coletados em todas as páginas de organizações feministas (114) cadastradas em uma rede social digital (Facebook). Com base nos resultados argumentamos que os feminismos contemporâneos fazem parte de uma quarta onda caracterizada no trabalho pela mobilização via meios de comunicação digitais, adoção da interseccionalidade e organização em forma de coletivos. Além de apontar traços dos feminismos contemporâneos, o texto problematiza a novidade e a homogeneidade por vezes associadas à quarta onda e às suas características.
CONTRIBUIÇÕES DE VIRGÍNIA LEONE BICUDO E NEUSA SANTOS SOUZA PARA UMA PSICOLOGIA BRASILEIRA ANTIRRACISTA
Authors: Navasconi Paulo Vitor Palma , Moscheta Murilo dos Santos
Published: October 2023

Resumo O presente artigo tem como objetivo discutir as contribuições teóricas de Virgínia Leone Bicudo e Neusa Santos Souza para o campo da Psicologia Social, bem como refletir sobre o modo como uma política de circulação dos conhecimentos científicos age de modo a resistir a essas contribuições. Metodologicamente, este artigo se orienta a partir de uma meta-análise qualitativa. Os resultados apontam que desnaturalizar a não-presença da população negra nos espaços de produção de conhecimento, trazer à tona suas produções intelectuais e, ainda, suas experiências enquanto sujeitos ativos da história, é urgente para a transformação desse cenário e, sobretudo, para uma democratização efetiva das universidades e do conhecimento. Por isso, conclui-se que as produções de Bicudo e Souza podem ser um recurso para se pensar sobre a emergência da construção de uma Psicologia Social Antirracista, rompendo com as matrizes colonialistas e as lógicas maniqueístas.
BRANCO NO PRETO: REVERBERAÇÕES DA BRANQUITUDE NA PSIQUE NEGRA
Authors: Hilário Leomir Cardoso , Lima Sophia Helena Rito
Published: October 2023

Resumo O presente trabalho busca analisar os efeitos do denominado “pacto narcísico” da branquitude sobre a psique dos indivíduos de cor. Esse acordo, em suma, é caracterizado por um contrato não verbal entre corpos brancos para manutenção de seus privilégios. O objetivo deste estudo é investigar as reverberações desse pacto em corpos negros, principalmente no que se refere a suas emoções e afetos, a partir de dados bibliográficos e de experiências clínicas. Constituir-se como negro em um universo que preza pelo ideal da brancura significa experimentar um “não lugar”, que resulta em danos psíquicos à comunidade negra. Desse modo, apostamos na decolonização da psicologia como ferramenta para criar novas formas de ser e de estar no mundo.

Resumo O debate sobre os efeitos psicossociais do racismo ganha crescente presença no campo da Reforma Psiquiátrica Antimanicomial. Consideramos que a manicomialização no Brasil tem ancoragem na colonialidade, configurando o manicolonial: a vinculação do significante negro à loucura. Visando investigar movimentos críticos, acompanhamos, de 2019 a 2021, na perspectiva metodológica da pesquisa cartográfica, dois coletivos antirracistas na Rede de Atenção Psicossocial do Município de São Paulo - Kilombrasa e Café Preto. O material colhido, em uma participação-observante das atividades; entrevistas e rodas de conversa com os profissionais, foi trabalhado na forma de fragmentos narrativos. A prioridade da experiência relacional, como racialização - enegrecer - e como experiência diaspórica - desnortear -, produz efeitos antirracistas e um resgate da radicalidade ético-política libertária da Luta Antimanicomial. Todavia, dessa vez, radicalizada como antimanicolonialidade: ressignificação do louco e do negro em um vaivém no Atlântico negro, em um pensamento da travessia contrário ao pensamento fixo, característico da manicolonialidade.

Resumo Este artigo é um desdobramento da tese de doutorado que trata das relações e processos de subjetivação entre equipes técnicas e famílias na rede de saúde mental. Neste contexto, o trabalho aborda forças conservadoras e possibilidades de resistência ao poder. O racismo está presente no cotidiano de pessoas que convivem com situações de sofrimento mental, mas poucas vezes esse marcador social é abordado nos serviços, caracterizando o silenciamento de experiências vividas. A metodologia utilizada foi a cartografia, incluindo pesquisa de campo, permitindo rastreamento de processos e considerando o posicionamento político de quem pesquisa, com orientação para práticas comprometidas com transformações sociais. A análise dos dados produzidos associa perspectiva interseccional sobre as demandas em saúde mental à esquizoanálise, buscando a construções de saída dos impasses entre familiares e equipes. Concluímos que sustentando indagações sobre modos de nos relacionar e revisitar nossa história, podemos construir práticas coletivas antirracistas na saúde mental.

ABSTRACT Objective: To analyze the perspectives and practices of personnel involved in family planning with women at reproductive risk due to chronic diseases. Method: Qualitative study in which physicians and nurses from primary care centers in a state in central Mexico were interviewed. Interviews were transcribed and analyzed under the Grounded Theory proposal. Results: The perspectives and practices in family planning interventions are unilaterally framed in the biomedical model. Three categories of analysis emerged: “The battle”, “Convince by imposing”, “Monitor them and catch them”. Conclusion: It is necessary to promote competencies in interculturality, gender perspective and human rights to make the intervention more of a counseling and less of a prescription for life projects.

Published: October 2023

ABSTRACT Objective: Study the prevalence of burnout and the salivary biomarkers in military police officers in the São Paulo health-care team who worked during the Covid-19 pandemic in Brazil. Method: An observational cross-sectional study was conducted in a sample of 104 participants distinguished by age, skin color, gender, military rank, function performed, length of service, use of medications, smoking, alcohol consumption, and income. The analysis of the social demographic data collected used an adapted Maslach Burnout Inventory and saliva examination through Fourier transform infrared spectroscopy. The statistical tests of chi-square, PLS-DA, and hypothesis were fixed at the 95% confidence. Results: The social demographic indicators presented statistical association with burnout, with chi-square 62.72 (p<0.05). The prevalence of burnout (80.77%) and risk of development (19.23%) were observed. The presence of biomarkers in saliva (amide, genetic fragments and polysaccharides) in those experiencing burnout aligned with current literature. Conclusion: Of the total sample, 80.77% had burnout and 19.23% risk of developing the disease. Young white women, in the role of health assistants, with median income between 3 and 6 times the minimum wage and with less than 10 years of service`s length had the highest prevalence of burnout in relation to their peers. There was an association of social demographic indicators with measured stress levels. Salivary biomarkers were also associated with stress in the initial phase of burnout. There is a pressing need for further studies, aiming to support greater knowledge for this population researched.

ABSTRACT The use of spontaneous species from the Caatinga biome as green manure is a promising practice in increasing the productivity of agricultural systems and sustainable exploitation of the environment. This study aimed to estimate the maximum physical and economic efficiencies of radish agroeconomic characteristics in monocropping as a function of roostertree (Calotropis procera (Ait.) R. Br) biomass amounts in two cropping seasons in a semi-arid environment. The experimental design was randomized complete blocks with five treatments and five replications. The treatments consisted of different roostertree biomass amounts: 16, 29, 42, 55, and 68 t ha-1 on a dry basis, incorporated into the soil. In each block, two additional treatments were added, one without fertilization (control) and the other with mineral fertilizer, for comparison purposes with the maximum efficiency treatment. The radish cultivar planted was ‘Crimson Gigante’. The fertilization of the radish to obtain the maximum optimized productive efficiency (9.56 t ha-1) was possible with the incorporation of 50.86 t ha-1 of C. procera dry biomass into the soil. The maximum optimized agroeconomic efficiency (based on a net income of 37,641.08 R$ ha-1) of radish cultivation was obtained with 44.39 t ha-1 of C. procera dry biomass added to the soil. The rate of return and the profit margin obtained were 2.94 R$ for each real invested, with a profit margin of 62.55%. The use of biomass from the C. procera green manure is a viable technology for producers who practice radish monoculture in a semi-arid environment.

ABSTRACT Water quality and soil quality are of great importance for crop yield in the context of small-scale irrigated agriculture in the Northeast region of Brazil. In this respect, this study aimed to determine changes in soil fertility and resistance to root penetration caused by fertigated cropping, as compared to soil under native forest. In each area, a non-regular sampling grid was established, which consisted of 87 georeferenced points in the melon cultivated area and 8 points in the native forest area. At these points, samples were obtained at depths of 0-10, 10-20, 20-30 and 30-40 cm. The determinations performed included soil physical, chemical and mechanical attributes. Multivariate analysis techniques and geostatistical procedures were used to analyze and interpret the data. The cultivation of the Vertisol altered all the variables studied, compared to the area under native forest. Soil decompaction and increase in phosphorus content were positive effects, while organic matter decomposition and reductions in potassium, calcium, magnesium and cation exchange capacity were negative effects. Sodium content and porosity parameters were prominent factors in soil alterations.

ABSTRACT Management of nitrogen fertilization and light interception of pastures contributes to forage production in regions with low water availability. Therefore, the objective was to evaluate the effect of different nitrogen doses and light interception levels on the growth of Panicum maximum cv. Tanzania under different irrigation managements. The experiment was carried out in a greenhouse, using a factorial scheme (5 x 2 x 2), corresponding to five irrigation depths (40, 60, 80, 100, and 120% of actual evapotranspiration), two canopy light interception levels (90 and 95%), and two nitrogen doses (300 and 600 kg N ha-1 year-1). The highest biomass production occurs under irrigation with 120% of evapotranspiration. However, the best structural characteristics (tillering and number of leaves) occur with 100% of evapotranspiration, regardless of nitrogen dose and light interception level. Interruption of growth with 95% of incident light and fertilization with 600 kg N ha-1 year-1 promoted greater tillering, number of leaves and leaf length, regardless of the irrigation level. Tanzania grass management with an interruption of growth with 95% of incident light, 600 kg N ha-1 year-1, and irrigation with 80% of actual evapotranspiration led to tillering and number of leaves only 11% lower than the values found in the other treatments irrigated with 100% of actual evapotranspiration. Interruption of growth with 95% of incident light and fertilization with 600 kg N ha-1 year-1 improve the performance of Tanzania grass under deficit irrigation.

Published: October 2023

ABSTRACT Soil management carried out in areas with sugarcane production causes changes in the soil physical attributes, and geostatistics makes it possible to study the behavior of the spatial distribution of these variations. This study aimed to evaluate the behavior of the spatial distribution of sugarcane yield averages according to the altitude and soil physical attributes along a transect in Goiana, Pernambuco, Brazil. Sugarcane yield averages, altitudes, and soil physical attributes, such as soil bulk density, total porosity, micro and macro porosity, sand (total, coarse, and fine), silt, and clay, in the 0.00-0.20 and 0.20-0.40 m soil layers were determined at 20 m intervals along the transect characterized by a toposequence of Ultisols and Spodosols. Exploratory data analysis was performed with the aid of descriptive statistics. The analysis of spatial dependence was performed using geostatistics. Pairs of semivariances were obtained using the GS+ software. The development and adjustment of the semivariograms were performed using the GEOEAS geostatistical tool. The highest contents of the finest soil particles were found in the lowest sections of the transect, in the 0.20-0.40 m soil layers. The highest amount of macropores was observed in the subsurface soil layer. The areas with the lowest amount of micropores showed the lowest average sugarcane yield, around 32.00 t.ha-1. The geostatistical model that best fitted the data set was the spherical model.

ABSTRACT Seeds subjected to abiotic stresses may have their physiological performance compromised, impairing the multiplication of species. Thus, the objective was to evaluate the germination and initial development of Tabebuia aurea seedlings subjected to water and salt stresses. Water stress was simulated with two osmotic agents (PEG 6000 and mannitol) at five osmotic potentials (0.0, -0.2, -0.4, -0.6 and -0.8 MPa). For salt stress, three osmotic agents (NaCl, KCl and CaCl2) were used at five concentrations (0, 6, 12, 18 and 24 dS m-1). The experiments were conducted under a completely randomized experimental design, with four replicates of 25 seeds, in a factorial scheme (osmotic agents × potentials), and the data were subjected to analysis of variance and regression. The variables analyzed were germination, first germination count, germination speed index, root and shoot length, and seedling root and shoot dry mass. The results showed that water and salt stresses reduced the germination and vigor of T. aurea seeds, with water stress being more harmful to the species, especially when induced by PEG 6000. Of the salts used, the one that most harmed the species was CaCl2, followed by NaCl and KCl.

Resumo Este artigo busca fornecer elementos para a compreensão da estrutura do partidarismo no Brasil, investigando os componentes socioeconômicos, atitudinais, ideológicos e comportamentais dos diferentes tipos de eleitores no país. Utilizando o método Grade of Membership , construiu-se uma tipologia multidimensional de eleitores em que foram delineados três perfis extremos: o dos “Radicais céticos politicamente sofisticados”, o dos “Apáticos socialmente desfavorecidos” e o dos “Moderados politicamente engajados”. A análise apontou indícios de que uma parte relevante dos eleitores brasileiros mostra disposição a se engajar na política e se identificar com partidos, enquanto a apatia e a insatisfação política são, paralelamente, fenômenos palpáveis. Contudo, tanto a manutenção de atitudes partidárias positivas quanto negativas parecem estar associadas a maiores níveis de sofisticação cognitiva.
Posicionamiento Subjetivo y Condición Socioeconómica en América Latina (2006-2020): Una Aproximación Desde el Análisis Multinivel
Authors: Marqués Perales Idelfonso , Rodríguez de la Fuente José
Published: October 2023

Resumen La percepción sobre la posición que ocupan los individuos en la estratificación social ha sido uno de los interrogantes clásicos de la sociología. Diversos análisis concuerdan que esta percepción se ve condicionada tanto por la posición social objetiva, así como por características contextuales de las sociedades en las que viven las personas (riqueza, desigualdad, pobreza, etc.). En el presente artículo analizamos el fenómeno en 17 países latinoamericanos a lo largo de los años 2006-2020, empleando un análisis multinivel que nos permite conocer la relación entre factores individuales y agregados. Los resultados señalan que, por un lado, como en otras sociedades, existe una propensión hacia posiciones intermedias de la escala social, manteniéndose una considerable importancia del efecto del estatus social objetivo sobre el estatus subjetivo a nivel individual. Asimismo, a nivel agregado, se aprecia que el grado de bienestar económico y de riqueza que presentan los distintos países actúan como condicionantes contextuales sobre el modo en que las personas se posicionan en la escala social.

Authors: Trevisol Joviles Vitório , Brasil André
Published: October 2023

ABSTRACT This paper presents the results of a study on the evaluation of research and graduate education in the Netherlands. The policies implemented in the country over the last four decades have consolidated a sui generis and stable evaluation system, contributing to strengthening the country's scientific leadership on the international scene. The Dutch experience has inspired several countries, and its lessons could also be relevant for the Brazilian reality. In this context, this study aimed to analyse the main characteristics of the Dutch system, understand the role of self-evaluation within that system and present a self-evaluation experience conducted by a noteworthy research centre from Leiden University. From the lessons learned, we conclude by presenting some subsidies for improving the evaluation of graduate education conducted in Brazil.

Authors: Nascimento Maria Thaís Mota do , Libardi Suzana Santos
Published: October 2023

ABSTRACT This work registers a research carried out with quilombola children, preadolescents and elderly people presenting the following topic: the construction processes of black and quilombola identities and self-affirmation. The research aimed to identify racial- and cultural-defined factors of these individuals’ identities; presenting the relations between racial identity and quilombola identity, in order to comprehend how such social constructions are related to each other and how they are managed by individuals from different generations. The research was conducted at the quilombola community Serra das Viúvas (Alagoas). A qualitative research was carried out with group workshops inspired by focal groups. A group of two elderly people and 37 children and preadolescents participated in the research. The results show generational factors involved in racial self-affirmation, as well as in being a quilombola, factors which were presented differently by young and elder participants.

Abstract The objective of this work was to determine the fatty acid profile of artisanal Minas cheese from seven certified regions in the state of Minas Gerais, Brazil. A total of 78 samples were collected in regions where the producers were registered by Instituto Mineiro de Agropecuária. For lipid profile determination, different cheese varieties from the following regions were analyzed: Canastra, Serro, Araxá, Serra do Salitre, Triângulo Mineiro, Campo das Vertentes, and Cerrado. The lipid profile of Serra do Salitre and Araxá cheeses was similar in caproic acid (C6:0), total polyunsaturated fatty acids, and ratio of polyunsaturated and saturated fatty acids. In the other regions, lipid profile differed due to associations with specific fatty acids, such as those of the cheeses from Triângulo Mineiro with C20:5n3, of Cerrado with C20:4n6, of Canastra with C8:0, of Serro with C22:2 and C22:6n3, and of Campo das Vertentes with C17:0, C18:0, and C20:0. The fatty acid profile and nutritional indices related to the lipid profile of artisanal Minas cheeses differ according to the region of origin. The content and profile of omega 3 fatty acids are significant parameters to differentiate artisanal Minas cheeses. Serro artisanal Minas cheese presents superior nutritional indices concerning fatty acid profile than the other studied cheeses.

Abstract The objective of this work was to determine the sample size necessary for estimating the means of wheat (Triticum aestivum) traits, obtained through measurement, counting, and weighing. Seventeen uniformity trials were performed with 1,790 plants harvested randomly, whose following traits were evaluated: lengths of the main stem and main stem ear (measurement); number of leaves, stems, and ears (counting); and mass of fresh and dry matter of leaves, stems, and ears (weighing). The Bartlett and Kolmogorov-Smirnov tests and Welch’s analysis of variance were performed. Skewness, central tendency, and variability were determined, and sample size was calculated to estimate the means of the 13 evaluated traits, considering estimation errors (semi-amplitudes of the 95% confidence interval) equal to 5, 10, 15, and 20% of the mean. There is a decrease in the sample size to estimate the means of wheat traits obtained through weighing, counting, and measuring, in this order. In an experiment to estimate the mean of wheat traits obtained by weighing, counting, and measuring with a maximum error of 10% of the mean at a 95% confidence interval, 117, 76, and 9 plants per treatment are needed, respectively.

Published: October 2023

Abstract The objective of this work was to evaluate the potential of cover plants in reducing the population of the two-spotted spider mite, Te t r a n y c h u s urticae, in soybean. Seven host plants – cotton (Gossypium hirsutum), Urochloa ruziziensis, crotalaria (Crotalaria juncea), corn (Zea mays), radish (Raphanus sativus), soybean (Glycine max), and sorghum (Sorghum bicolor) – were evaluated for their effect on T. urticae biological parameters (oviposition, development stages, and survival) and preference for volatile odors (using a Y-tube olfactometer). Tetranychus urticae preferred cotton and showed a higher population growth rate on this host plant. The survival and oviposition of T. urticae was prolonged in radish and crotalaria plants, whereas juveniles did not complete their immature development on U. ruziziensis leaves. No preference was observed between the volatile odors of U. ruziziensis, radish, and crotalaria. Urochloa ruziziensis can reduce T. urticae populations in soybean plants.

Resumo Em Portugal, a Licenciatura em Educação Básica, criada em virtude da reformulação dos cursos decorrente do Processo de Bolonha, constituiu uma novidade no âmbito da formação inicial de professores e uma especificidade da formação dos profissionais que educam crianças entre 0 e 12 anos. No presente trabalho procurou-se compreender como as diferentes instituições de ensino superior operacionalizaram as orientações da tutela, relativamente ao desenho curricular da Licenciatura em Educação Básica, e que decisões tomaram no âmbito da sua autonomia. Para tal, procedeu-se a uma análise comparativa dos planos de estudo de 25 cursos de Licenciatura em Educação Básica existentes no país e em vigor no ano letivo de 2021/2022, quanto à organização das diferentes componentes de formação da licenciatura (formação na área de docência, formação educacional geral, didáticas específicas e iniciação à prática profissional). Fruto da análise realizada, é possível concluir que os cursos de Licenciatura em Educação Básica se caracterizam por uma valorização, no âmbito da autonomia das instituições, da componente de formação educacional geral e por uma organização curricular alicerçada numa lógica eminentemente disciplinar. No entanto, sobressaem grandes diferenças relativamente à forma como a iniciação à prática é operacionalizada, nomeadamente quanto: ao número de créditos e às horas de estágio; ao número de contextos que a iniciação à prática profissional contempla; e ao momento de introdução destas unidades curriculares/disciplinas ao longo do curso.
