Published: August 2024

Context. Recent studies recognise that the use of the School as a Learning Organisation (SLO) approach in educational management is the key factor ensuring a general education institution’s ability to effectively implement the education policy goals and adapt to change as the use of SLO. Although vocational education has different predominant goals and different target groups, likewise general education, it is exposed to dynamic change and new challenges.Purpose. Within the framework of the study, it was researched whether and how SLO can be applied in vocational education as the use of SLO facilitates a high level of professional competence of the management and academic staff, enhances common strategic vision, responsibility and autonomy, diverse collaboration, effective resource management, and the dissemination of knowledge and good practice, which are also important in vocational education.Methods. Using qualitative data analysis, the paper analyses the experience of EU and OECD countries in the implementation of SLO in vocational education and identifies, which dimensions of the SLO model are represented in the policy and practice of vocational education in Latvia. In the focus group interviews with representatives of vocational education institutions of Latvia, the characteristics of the SLO approach in vocational education were studied, challenges were described and solutions proposed for the targeted implementation of the SLO approach in vocational education in Latvia.Results. All 7 dimensions of the SLO can be found in the education policy documents of the EU and OECD countries and Latvia, as well as in the focus group interviews, which shows that there is a gradual progress towards the transformation of vocational education institutions into learning organisations.Conclusions. For education policy makers: Since the features of SLO are only partially visible in vocational education documents in Latvia, the framework should be improved to cover all dimensions of the SLO, and norms and agreements on collective understanding should be harmonised in policy documents. For school representatives: Raise awareness of the staff of vocational education institutions of the essence of the SLO and its role in improving the quality of education and ensure that all dimensions of SLO are understood and addressed appropriately. For entrepreneurs: Help define the diverse, varied manifestations of professions in the sector in order to engage the individual potential of learners as effectively as possible. For researchers: Help find ways to resolve controversies by identifying good practice and research.

The female nomination on the basis of marital status in Russian Internet texts: functional and linguo-ecological aspects
Authors: Balyunis Evgeniia
Published: August 2024

The article is devoted to the gendered lexical unit which constitutes initial abbreviation derived from the idiom «razvedenka s pricepom» (divorsed woman with a child) and is
actively used by Russian speaking Internet users to denote a female person on the basis of her marital status. The article describes the history of the appearance of the unit, its derivational and semantical characteristics, semantic and contextual connections and its functioning specifics in the Internet texts. The research is conducted on the material of the author's corpus of the contexts of use including 1 255 speech products published in between 2014 and 2023 in the communicative space of such social platforms as (425 units), vk.com (336 units), YouTube (190 units), Yandex.Dzen (173 units). The author applies the methods of quantative, semantic, conceptual, derivational, contextual and discursive analyses. The article specifies that the gendered abbreviation is derived from the linguocynical idiom, having been used in the male speech long before the spread of the Internet. The research reveals that the abbreviation use underlines the artifact conceptual metaphor generated by the initial phraseological combination. The divorced mother deanimization is regularly strengthened by the abrriviation's contextual environment. It reveals that 1 175 contexts (93,62 %) contain verbalized speaker's conception of financial aspect in sexual, romantic or family relationship caused by the actualization of consumer strategy in interpersonal ineteraction and by the ubiquitous consumeristic philosophy. It proves that the use of the innovation RSP is a feature of male Internet users' speech (982 contexts; 78,24 %) and is not typical for female speech (270 contexts; 21,51 %). In female speech the abbreviation carries out primarily the metalinguistic function and much less frequently nominative and evaluative functions. In the Internet texts produced by male persons the nomination not only promotes expressing the divorced mother with a child negative evaluation but also facilitates deconstruction, deaxiologization and desacralization of the concept «Mother». This allows us to qualify the abbreviation as a linguo-perversion which is a special kind of language trauma which represents a speech phenomenon generating the traditional symbol ambivalence and leading towards worldview destruction.

Published: August 2024

ABSTRACT: This paper discusses how children and adolescents lived the covid-19 pandemic as a generational experience, seeking to understand their interpretations of the social interactions reconfigured by the social distancing measures adopted to combat the disease. Data were obtained from two studies conducted with children and adolescents aged 8 to 14 years, residing in 33 cities from the Metropolitan Region of Belo Horizonte and 27 administrative regions of the Federal District. Both studies adopted a mixed methodology, collecting census data using questionnaires, broadened by open questions. The analysis points to a concern with inter and intragenerational solidarity, and shows that children and adolescents reject dichotomies, especially those that separate adults and children, and express their criticism about the context and the political and individual actions resulting from it.

Authors: Silva Elaine de Carvalho , Elias Nassim Chamel , Barros Romariz da Silva
Published: August 2024

Abstract Studies using teaching techniques derived from Applied Behavior Analysis (ABA) principles have shown promising results, based on empirical evidence, in teaching speaker and listener behavior to individuals diagnosed with Autism Spectrum Disorder (ASD). Our objective was to compare the effects of two teaching procedures on the acquisition of intraverbal-tact and listener relations involving spatial relations concerning body parts in six boys with autism. In “intraverbal-tact-to-listener”, questions in the presence of non-verbal stimulus were taught and then tested for emergence of listener responding. In “listener-to-intraverbal-tact”, listener responses were initially taught and the emergence of intraverbal-tact responses were tested. An alternate treatment design with an embedded nonconcurrent multiple baseline design across participants was used. The results suggest that the intraverbal-tact-to-listener protocol was more effective. Such data concerning to body parts spatial relations replicate findings for other repertoires.

ABSTRACT: This study evaluated the stability of anaerobic digestion and biogas production from the manure of laying hens fed diets containing different mineral sources and rosemary oil concentrations. Manure was obtained from 288 semi-heavy laying hens, 30 weeks old, and collected for 112 days. A completely randomized design was used in a 2×3 factorial scheme with repeated measures, considering two mineral sources (inorganic and organic) and three concentrations of rosemary oil (0, 100, and 200 mg kg-1). Twelve continuous bench digesters (7.5 kg) were operated with a hydraulic retention time of 30 days and daily loads of 5% total solids, for 90 days. A weekly analysis of influents and effluents was performed by measuring the values of total solids (TS), volatile solids (VS), pH, ammonia nitrogen (ammonia N), intermediary alkalinity (IA), partial alkalinity (PA), and the relationship IA:PA; biweekly analysis of total nitrogen (N) and total phosphorus (P) concentrations; and daily measurement of biogas production data to calculate the biogas production potential of the manure. Manure from laying hens fed with organic minerals has greater potential for biogas production and greater TS and VS reduction than manure from hens supplemented with inorganic minerals. Laying hen diets containing up to 200 mg kg-1 of rosemary oil do not present the risk of anaerobic digestion failure.

ABSTRACT: This study evaluated the inhibitory effect of ozone gas (O3) on the mycelia and zoospores of Pythium insidiosum and verified the morphological changes it caused on the hyphae. The effects of O3 were evaluated on the mycelia (n = 21) and zoospores (n = 10) of P. insidiosum. O3 was bubbled into vials with sterile distilled water and mycelium or induction medium and zoospores. After 15 minutes, aliquots of mycelia and zoospores were grown on yeast agar at 37 °C/96 hours. Ozonated flasks were incubated at 37 ºC/72 hours; and every 24 hours, aliquots were subcultured at 37 ºC/96 hours. Transmission (TEM) and scanning (SEM) electron microscopy of O3-exposed hyphae were performed. The results revealed that O3 inhibited microorganism growth in all ozonated suspensions. Conversely, in control suspensions, P. insidiosum growth occurred within 24 hours of incubation. In the SEM, the treated hyphae presented cavitations and cell wall continuity loss; in the TEM, the organelles and cytoplasmic membrane disappeared, and the cell wall was retracted. We demonstrated, for the first time, that O3 causes irreversible damage on P. insidiosum hyphae and prove in vitro oomicidal action on zoospores and hyphae.

Abstract Marine organisms produce a variety of compounds with pharmacological activities. In order to better comprehend the medicinal value of five particular seaweed orders Ulvales (Ulva intestinalis), Bryopsidales (Codium decorticatum), Ectocarpales (Iyengaria stellata), Dictyotales (Spatoglossum aspermum) and Gigartinales (Hypnea musciformis), a bioactive analysis including the screening of phytochemical components, antioxidant and antimicrobial activities was the aim of the investigation. The species include U. intestinalis was collected from Sandspit, while C. decorticatum, I. stellata, S. aspermum, and H. musciformis were gathered from Buleji. These species evaluated for their ability to inhibit human infectious gram positive pathogens Staphylococcus aureus, Staphylococcus epidermidis as well as gram negative bacteria Escherichia coli. Additionally vegetable pathogen Fusarium oxysporum, and fruit pathogens (Aspergillus niger and Aspergillus flavus) were evaluated to determine the zone of inhibition. Two organic solvents, ethanol and methanol, were used to prepare seaweed extract. The disc diffusion method was utilized to quantify the zone of inhibition and the DPPH method was employed to measure the antioxidant activity. The study unveiled various phyto-constituents in the tested seaweeds, with flavonoids, tannins, and proteins found in all selected species, while saponins, terpenoids, and carbohydrates were absent in I. stellata and S. aspermum. Notably, ethanolic extracts of I. stellata and S. aspermum demonstrated superior higher antioxidant activity, with increasing percentages of inhibition from 1 to 6 mg/ml. Furthermore, the findings indicated that the ethanolic extract of U. intestinalis displayed the highest resistance against F. oxysporum and A. flavous among other seaweeds. Meanwhile, the ethanolic extract of C. decorticatum exhibited the highest resistance against A. Niger. Additionally, the ethanolic extract of I. stellata and H. musciformis displayed the highest resistance against the gram-negative bacteria E. coli and the gram-positive bacteria S. epidermidis, whereas the methanolic extract of U. intestinalis demonstrated the highest resistance against the gram-positive bacteria S. aureus. The findings of this investigation show that a range of bioactive compounds with antioxidant properties are involved in the antimicrobial activities of disease-causing pathogens.

Abstract Human activities are altering the existing patterns of Land Use Land Cover (LULC) and Land Surface Temperature (LST) on a global scale. However, long-term trends of LULC and LST are largely unknown in many remote mountain areas such as the Karakorum. . The objective of our study therefore was to evaluate the historical changes in land use and land cover (LULC) in an alpine environment located in Islamabad Capital Territory, Pakistan. We used Landsat satellite pictures (namely Landsat 5 TM and Landsat 8 OLI) from the years 1988, 2002, and 2016 and applied the Maximum Likelihood Classification (MLC) approach to categorize land use classes. Land Surface Temperatures (LST) were calculated using the thermal bands (6, 10, and 11) of Landsat series data. The correlation between the Human Modification Index (HMI) and LULC as well as LST was evaluated by utilizing data from Google Earth Engine (GEE). Over the study period, the urbanized area increased by 9.94%, whilst the agricultural and bare soil areas decreased by 3.81% and 3.94%, respectively. The findings revealed a significant change in the LULC with a decrease of 1.99% in vegetation. The highest LST class exhibited a progressive trend, with an increase from 12.27% to 48.48%. Based on the LST analysis, the built-up area shows the highest temperature, followed by the barren, agricultural, and vegetation categories. Similarly, the HMI for different LST categories indicates that higher LST categories have higher levels of human alteration compared to lower LST categories, with a strong correlation (R-value = 0.61) between HMI and LST. The findings can be utilized to promote sustainable urban management and for biodiversity conservation efforts. The work also has the potential of utilizing it to protect delicate ecosystems from human interference and to formulate strategies and regulations for sustainable urban growth, including aspects of land utilization and zoning, reduction of urban heat stress, and urban infrastructure.
Work and management of women in family farming: an analysis from feminist and gender studies
Authors: Herrera Karolyna Marin , Desconsi Cristiano , Birochi Renê , Pacífico Daniela Aparecida
Published: August 2024

Abstract: This article aims to reflect on the theoretical possibilities for studies on rural women at work and managing family establishments based on the contributions of gender studies and feminism. Thus, we review the theoretical path of gender and work in the rural environment to critically reflect on the concept of management, address the specificities of management in rural establishments, and, finally, indicate theoretical paths for understanding the management of rural women. The analysis identifies two facets of management: instrumental, from management, and emancipatory, intrinsic aspect of organizing. In the results, we argue that the organizing agencies carried out by women offer alternatives to undo the managerialism embedded in organizational processes, which makes women's performance invisible, thus enabling the emergence of new access routes to reposition the role of women in rural establishments. In conclusion, this new approach considers that the emancipatory and collective aspects present in women's organizing may indicate a new way to address the concept and practices of management.

Resumo: Este artigo objetiva refletir sobre as possibilidades teóricas para os estudos sobre as mulheres rurais no trabalho e na gestão de estabelecimentos familiares tomando como base as contribuições dos estudos de gênero e dos feminismos. Para isso faz-se uma revisão sobre o percurso teórico de gênero e trabalho no meio rural, para então refletir criticamente sobre o conceito de gestão, abordar as particularidades de gestão em estabelecimentos rurais e, por fim, apontar caminhos teóricos para compreensão da gestão de mulheres rurais. Ao longo da análise, identificam-se duas facetas da gestão, a instrumental, proveniente do gerencialismo (management) e a emancipatória, aspecto intrínseco ao organizar (organizing). Nos resultados defendemos que as agências do organizar realizadas pelas mulheres oferecem alternativas para desfazer o gerencialismo embutido nos processos organizacionais, que invisibiliza a atuação das mulheres, possibilitando, assim, a emergência de novas vias de acesso para reposicionar o papel das mulheres em estabelecimentos rurais. Concluimos que essa nova abordagem da gestão considera que os aspectos emancipatórios e coletivos presentes no organizar das mulheres poderão indicar um novo caminho para tratar do conceito e das práticas de gestão.

ABSTRACT Potassium is a nutrient with the potential to increase plant tolerance to salt stress. The aim of this study was to evaluate the production and quality of kale subjected to salt stress and potassium concentrations in a protected environment. The experimental design was in split plots, with plots composed of five nutrient solutions (control treatment, S1 - standard nutrient solution prepared in low-salinity water, 0.5 dS m-1 (500 mg L-1 of KNO3), and four nutrient solutions prepared in brackish waters (3.5 dS m-1) containing four concentrations of KNO3 (S2 - 500 mg L-1, S3 - 625 mg L-1, S4 - 750 mg L-1, S5 - 1,000 mg L-1), and subplots represented by two leaf kale cultivars (Manteiga and Manteiga da Geórgia). Leaf production variables and post-harvest physical and chemical qualities were evaluated. The saline nutrient solution with the addition of NaCl (S2) reduced production but did not reduce the post-harvest quality of kale. The extra addition of KNO3 at 25% (S3) was efficient in reducing the deleterious effects of salt stress on the variables leaf length, leaf area, leaf production, and number of bunches. The cv. Manteiga da Geórgia was more tolerant to salt stress than the cv. Manteiga.

ABSTRACT Storage is one of the main stages during grain production. The present study was conducted to evaluate the use of silo bags as an alternative for storing landrace cowpea grains. The experiment used samples of the Arigozinho, Manteiguinha, and Quarentão cowpea varieties from Cruzeiro do Sul - Acre, harvested in the 2021 crop season. The samples (500 g) were stored in raffia and silo bags for 30, 60, 90, and 120 days. The experimental design was completely randomized, arranged in a split-plot-in-time scheme (2 × 5) with four replicates. Storage conditions represented the plots: silo bags and raffia bags. The subplots comprised five storage conditions: 0, 30, 60, 90, and 120 days for each landrace cowpea variety. The insect species identified in all varieties was Zabrotes subfasciatus, with infestation ranging from 49% to 98% in raffia bags and less than 10% in silo bags over 120 days. A depreciation in grain quality was observed during storage in raffia bags. There was increase in electrical conductivity, fluctuations in water content, and reductions in bulk density and germination due to the higher degree of infestation in all the investigated varieties. The grains stored in silo bags showed minimal variations over the 120 days, maintaining their initial quality throughout the storage period. The bag silo storage system is an effective alternative for controlling Z. subfasciatus and maintaining the grain quality of the varieties Arigozinho, Manteiguinha, and Quarentão for a period of up to 120 days.

Published: August 2024

ABSTRACT The production process of non-centrifuged cane sugar (NCS) involves a significant release of steam and heat due to the evaporation of cane juices in saucepans over a solid fuel oven. This results in a warm and moisture-saturated environment, which can be suffocating for workers. This study aimed to evaluate the bioclimatic behavior of an NCS processing facility, based on the wet bulb globe temperature (WBGT) index. In addition, solutions are suggested to mitigate possible adverse effects of heat stress. This evaluation utilized computational simulations to determine the thermal comfort perceived by the workers. The accuracy of simulations was verified against temperature and relative air humidity data collected from the facility. Bioclimatic simulations encompassed twelve treatments, involving modifications to the enclosure on the walls and lantern window, incorporating three types of roof material. The WBGT index was determined by considering the effects of the radiant heat generated by the oven and the natural ventilation area on the facility’s temperature and relative air humidity. This helps to assess the comfort experienced by the workers. The thermal zone of the oven presented heat stress conditions; therefore, rest periods and mechanical ventilation were suggested when dissipating heat and steam through natural ventilation is not possible. For workers exposed to high temperatures and thermal radiation, the use of an aluminized apron and infrared goggles for eye protection was recommended.

Published: August 2024

ABSTRACT Objective: To map evidence on nursing care for women with HELLP syndrome. Method: A scoping review with searches carried out in May 2023, independently, in the PubMed/MEDLINE, LILACS, Scopus, EMBASE, Web of Science, CINAHL, CAPES Theses and Dissertations Catalog and Cochrane Library databases, correlating the descriptors HELLP Syndrome, Nursing Care and Obstetric Nursing and its synonyms, without delimitation of time and language. Selection was carried out by three researchers independently and resolved by consensus. Results: Of the 129 studies, ten were selected, which made up the final sample. The studies date from 2004 to 2022, with a predominance of English language and clinical case studies. A greater occurrence of the syndrome was observed in second-time pregnant women in the second decade of life, with a gestational age from 32 weeks, which resulted in an emergency cesarean section, and all newborns were discharged accompanied by their mothers. Studies that described nursing diagnoses and focused on nursing care were retrieved. From the review, 39 nursing care were identified. Conclusion: This review pointed out the magnitude of the syndrome, however with a lack of studies.

ABSTRACT Objective: to compare empathy levels among nursing students at different course stages considering gender and age. Method: this study was conducted at the Faculdade Israelita de Ciências da Saúde Albert Einstein, employing a quantitative, descriptive, comparative and cross-sectional approach. The sample included 169 four-year Nursing undergraduate students. A sociodemographic questionnaire was used to collect information from August 2020 to April 2022 and the Multidimensional Interpersonal Reactivity Scale was used to measure empathy. The relationships between empathy and independent variables were analyzed using linear models and presented with estimated means, confidence intervals and p-values, with a significance level of 5%. Results: the comparison of empathy levels in different course periods did not reveal significant relationships with the course year. However, the lowest score on the three subscales occurred in the fourth year. When analyzing the relationship between course years and gender, no subscale showed significant differences. A significant difference in the Empathic Consideration subscale emerged in the second year when separating by course year, with higher scores for females. Conclusion: the study highlights the continued importance of teaching empathy in nursing training. Therefore, the use of the Multidimensional Interpersonal Reactivity Scale proves to be valuable for evaluating interventions and offering support for adjustments in educational strategies. Commitment to improving empathy throughout professional training and practice is essential to ensure truly patient-centered healthcare.

RESUMO Objetivo: Analisar a associação da insegurança alimentar (IA) com as doenças crônicas não transmissíveis (DCNTs) no contexto brasileiro. Métodos: O protocolo da revisão foi registrado no International Prospective Register of Systematic Reviews (PROSPERO). As buscas foram realizadas na LILACS e na PubMed (setembro/2022). Foram incluídos estudos observacionais realizados com a população brasileira, publicados a partir de 2003, que: (1) analisam a associação da IA com DCNTs; e (2) utilizam a Escala Brasileira de Insegurança Alimentar (EBIA). Foram excluídos estudos com gestantes e que associam a IA com câncer, infecções sexualmente transmissíveis e doenças musculoesqueléticas e respiratórias. Os estudos foram submetidos à avaliação da qualidade metodológica. Resultados: Foram incluídos 27 estudos transversais, dentre os quais 9 utilizaram dados secundários de inquéritos nacionais e os demais utilizaram dados primários. Os estudos revelaram associação da IA com sobrepeso e obesidade em diferentes faixas etárias. Conclusão: Os artigos incluídos não produziram evidências sobre outras DCNTs de interesse para a saúde no Brasil, como a diabetes e a hipertensão arterial. No entanto, contribuem para corroborar a relação já conhecida entre obesidade e IA. Estudos sobre a temática, com desenho longitudinal, devem ser incentivados.

Resumo Este trabalho estuda o incremento da resistência mecânica à flexão e força de ruptura de porcelanatos através da têmpera química. A troca catiônica resulta em tensões residuais de compressão na superfície do material. Foram selecionados porcelanatos técnicos (60×60 cm) com 100%, 90% e 77% da espessura padrão. Os porcelanatos foram prensados, secos e sinterizados em forno industrial. O processo de têmpera química foi realizado com uma mistura de sais de composição correspondente a 27% de nitrato de potássio (KNO3 > 99%) e 73% de fertilizante (K2O ~ 43%). O tratamento químico foi realizado a 480 ºC durante 25 min. Os resultados mostraram que as propriedades mecânicas do material atenderam à norma vigente (ABNT 10545-4 2018). Mesmo o material com 77% da espessura padrão, obteve-se um aumento de 15% na tensão de ruptura e 16% na força de ruptura. A análise de Weibull comprovou que as propriedades mecânicas foram incrementadas após a têmpera química.

Resumo A violência doméstica contra a mulher é um problema do campo da saúde, que tem na Estratégia Saúde da Família (ESF) importante via de enfrentamento. Este estudo buscou compreender as práticas de cuidado com esse público, elaboradas por trabalhadores e trabalhadoras da ESF e do Núcleo Ampliado de Saúde da Família. A pesquisa foi marcada pelo advento da pandemia do coronavírus, que impossibilitou a presença no campo. Assim, foram utilizadas a entrevista semiestruturada on-line como principal fonte de dados, e a Análise Temática como estratégia de análise. Observa-se que a construção do cuidado se dá principalmente a partir da valorização das tecnologias leves e dos saberes práticos, que se manifestam principalmente por meio do que os participantes denominam “protocolos intuitivos”. O estudo aponta ainda o medo de represálias, a desvinculação de julgamentos morais, a implicação da mulher, o desconhecimento da rede de assistência e a ausência de protocolos como principais desafios a serem superados. Também revela a importância do protagonismo dos saberes elaborados no trabalho vivo em ato para a formulação das estratégias de cuidado, articuladas com a Política Nacional de Atenção Integral à Saúde da Mulher, além da necessidade de novas produções com essa perspectiva.

Abstract The objective of this work was to estimate the relative yield that maximizes the profitability of the soybean crop in rotation with flood-irrigated rice. For this, 13 high-yield areas (from 2.6 to 5.2 ha) in lowland soybean-rice systems in Southern Brazil were selected before sowing. The calculation of production costs included seeds, seed treatment, fertilizers, lime, pesticides, irrigation, land, operational outsourcing, labor, and fuel consumption. The observed yield was transformed into relative yield by multiplying the quotient of the observed yield by the yield potential estimated by the CSM-CROPGRO-Soybean model. Water productivity was calculated as the ratio between the observed yield and available water during the crop cycle. Yield potential ranged from 6.1 to 7.4 Mg ha−1, whereas relative yield ranged from 45.3 to 101.2%. In addition, costs ranged from US$564.86 to US$1,122.86 per hectare, and profitability from US$767.18 to US$3,149.75 per hectare. The highest profitability of the soybean crop in rotation with flood-irrigated rice occurs with a relative yield between 67 and 84%.

Abstract The objective of this work was to estimate the repeatability coefficients of variables related to fruit and nut production, the minimum number of crops required for genotype selection, and the permanent phenotypic correlation coefficients between variables in a cultivated population of Amazon nut. A total of 40 genotypes from seeds, belonging to an agroforestry system implemented in 1995, in the state of Roraima, Brazil, were evaluated during ten years for six variables related to fruit and nut production. The genetic-statistical analyses were performed using the maximum restricted likelihood and best linear unbiased prediction (REML/BLUP) method, based on the basic model of repeatability, without an experimental design, of the Selegen-REML/BLUP software. Genetic variability between genotypes and a moderate regularity in the repetition of the studied variables between different harvests were detected. The number of harvests required to reach a coefficient of determination of 80% ranged from seven, for the variables average nut weight per fruit and number of fruits per plant, to nine, for average nut weight. The correlation results indicate the possibility of indirect selection for nut production through the evaluation of the number and weight of fruits per plant.

Abstract The development of supervision, monitoring, and support actions constitute relevant assistance for early career teachers since there are varied limitations of initial training and difficulties at the beginning of this professional activity. Given this scenario, the Hybrid Mentoring Program (HMP) works as an action to induce teaching in a constructive-collaborative research project that aims to offer early career teachers monitoring and support through a process called mentoring, in which an experienced teacher - with more than ten years of professional experience - accompanies early career teachers with a maximum of five years of experience, assisting them in the development of their professional skills, as well as in the foundation of new competence practices. In this article, we sought to identify and understand the training needs presented by early career teachers participating in a mentoring program. The theoretical frameworks involved early career teachers’ challenges, difficulties, and training needs. The research is qualitative, with interpretative descriptive analysis of digital narratives produced through the dialogue between two early career teachers and their respective mentors via different tools in HMP’s Moodle environment. The categories emerged from the readings of the data set, and the results indicate that the mentoring actions developed in the HMP made it possible to capture how the participants report their difficulties at the beginning of their teaching careers and how these configured as training needs to be worked on by the mentor-beginner dyad.

Steps in the embryonic development of crocodilians are usually species-specific, highlighting the plasticityof the process. Herein we describe intraspecific variation in the growth of embryos in three Black Caiman(Melanosuchus niger) nests monitored in situ in the Central Brazilian Amazon. Nests differed in which embryonic stagesthe first increases in total length and mass occurred. Differences from a previous study of the same species included thetiming of morphological characteristics such as the closure of the abdominal wall. Therefore, our data are indicative of theplasticity of embryonic development of Black Caimans in natural conditions.

Objetivo deste artigo é conhecer os tipos de observação meteorológica, analisar a diferença entre estações meteorológicas automáticas e convencionais, verificar a viabilidade das estações meteorológicas de baixo custo e de código aberto. Justifica-se pela necessidade de construção de estações meteorológicas de baixo custo, pois amplia o acesso aos seus sistemas e permite a coleta e utilização dos dados por pesquisadores, por produtores rurais e muitos outros agentes que se interessam pelas condições climáticas. O custo acessível das estações viabiliza a implantação de muitas estações nas áreas de recursos limitados completando as brechas nas redes de observação meteorológica e alargando a cobertura geográfica. A metodologia empregada foi de pesquisa bibliográfica. Utilizaram-se para a fundamentação teórica, textos acadêmicos indexados em sites como Google Acadêmico, Scielo e revistas científicas a fim de estabelecer parâmetros para discussão. Os resultados mostraram a possibilidade de montagem e calibração de uma Estação Meteorológica Experimental de baixo custo, mas apesar disso e da evolução tecnológica e das novas ferramentas de projeção de dados, as estações meteorológicas ainda são muito caras e pouco acessíveis.

Resumen El presente estudio tuvo por objeto estandarizar una prueba de ELISA en suero lácteo para optimizar la aplicación de esta técnica a la caracterización de la Rinotraqueitis Infecciosa Bovina (RIB). Se tomaron, para el efecto, 69 muestras de suero lácteo de animales positivos por neutralización y ELISA en suero sanguíneo y 105 de animales negativos por ambas pruebas. El valor promedio de los delta de densidad óptica (diferencia de promedios entre los pozos con antígeno y con control de antígeno) para los 105 sueros negativos fue de 0,04 con una desviación estándar de 0,02 y para los 69 positivos fue de 0,20 con una desviación estándar de 0,06. Con base en estos datos se determinó un punto de corte de 0,08 con el cual se logra una sensibilidad del 100% y una especificidad del 94%. La concordancia de los resultados entre las pruebas para los dos tipos de muestras fue del 97%. Estos resultados aportan un elemento más para la caracterización y el control o erradicación de esta enfermedad en el país. Finalmente se discute la importancia de optimizar aún mas esta prueba, mediante el uso de leche entera y de "pooles" de suero lácteo, que permitirían la aplicación de la prueba a estudios masivos de tamizaje en grandes poblaciones         Summary The objective of this study was to standardize an ELISa technique for serological testing of BHV-1 in milk serum. This technique is expected to facilitate large serological screening in milking cows. For this purpose, 69 samples from Nt and ELISA positives and 105 Nt and ELISA negatives animals were used. The average of optical densities for the negative samples was 0.04 +/- 0.02 and for the positive the averge was 0.20 +/- 0.06 based on this results we set a delta value of optical density of 0.08 as the cut off point for positivity. This value gives a sensibility of 100% and specificity of 94%. The concordance between serum Nt and serum ELISA and milk serum ELISA was of 97%. The standardization of this ELISA provides a new instrument not only for the characterization of the infection in our country but also for its control and eventual eradication. Finally we discuss the possibility of further optimizing by using straight milk or milk serum pools to facilitate further the massive screening of large populations.
