Biometric, Physical-Chemical And Microbiological Quality Indicators Of Tomatoes (Solanum Lycopersicum) Sold In Fairs And Supermarkets After Different Sanitization Treatments

As a perishable food, tomatoes have high humidity and nutritional conditions that favor the development of microorganisms and can put the health of those who eat them at risk. Thus, when tomatoes are consumed fresh, without being sanitized, they propagate pathogenic microorganisms, putting the consumer's health at risk. The aim of this study was to evaluate the physicochemical parameters and the incidence of microorganisms in salad tomatoes sold in street markets and supermarkets in the city of Paraíso do Tocantins after different sanitization treatments. A total of 100 tomato samples were purchased from supermarkets (MB, XP and TQ) in the West Zone (ZO) and the free market (CF) in the city of Paraíso do Tocantins. The fruit was transported to the Food Analysis and Fruit and Vegetable Processing Laboratories at the Federal Institute of Tocantins IFTO Paraíso do Tocantins campus, for biometric assessment (fruit mass, transverse and longitudinal diameters), treatment without sanitization, treatment with running water and treatment with 100 ppm sodium hypochlorite solution for 20 minutes, physicochemical evaluations (pH, total titratable acidity, total soluble solids, vitamin C and humidity) and microbiological quality (total coliforms, thermotolerant coliforms, Escherichia coli and evaluation of the presence of Salmonella sp.). The biometric analysis showed a mass of 178.20 grams, a transverse diameter of 72.46 millimeters and a longitudinal diameter of 57.82 millimeters. The physical-chemical evaluation showed average values for pH of 4.34, titratable acidity of 0.24%, soluble solids of 5.81 brix, humidity of 94.94% and vitamin C of 11.27 mg. There were total coliform counts of 1058 NMP/g, thermotolerant coliforms of 150.5 NMP/g, Escherichia coli of 13.15 NMP/g and no Salmonella sp. Treatment with 100 ppm sodium hypochlorite solution for 20 minutes reduced the amount of total coliforms by 97.91%, thermotolerant coliforms by 93.01% and Escherichia coli by 71%. The tomatoes sold in the city of Paraíso presented fruit within the physical-chemical and microbiological quality standards established by the legislation, so the tomatoes can be consumed without risk to the health of the consumer regardless of the establishment of purchase

Prediction of genotypic values via REML/BLUP and path analysis in maize half-sib families

Maize has significant relevance to food and economic security. The study aimed to evaluate the genetic gain between maize half-sib families, in the first cycle of recurrent selection, using the REML/BLUP methodology. Path analysis was also performed in order to understand the relationship between the agronomic traits. The experiment was conducted at the Federal Institute of Education, Science and Technology of Triangulo Mineiro – Campus Uberlandia. The agronomic traits evaluated, were: plant height (PH), ear height (EH), stem diameter (SD), ear length (EL), ear diameter (ED) and grain weight (GW). The results indicated significant differences only for the traits EL, GW and ED. A high coefficient of genetic variation (CVg) was observed for the traits EL, GW and ED, with only ED presenting a coefficient of relative variation (CVr) above one. The REML/BLUP methodology demonstrated high accuracy values and the estimates of gains were promising, with values of 24.07%, 21.88% e 18.23% for EL, GW and ED, respectively. Path analysis revealed the possibility of indirect gains in GW through EL.

EXTENSÃO EM CURSOS TÉCNICOS NA MODALIDADE A DISTÂNCIA

This work deals with the result of the research developed within the Professional Master's Program in Professional and Technological Education – ProfEPT, which sought to investigate the reasons for the low participation in the extension actions of students of the Subsequent Technical Course in Didactic Multimedia, offered in the distance modality by the Federal Institute of Espírito Santo. As hypotheses for this problem, the lack of time and space within the workload of the servers for extension practices, school culture focused on teaching activities, and the profile of students who do not have time available for extra-curricular activities because they are, for the most part, adults and workers. The general objective was to propose actions that would encourage the extension practice within the course, and the execution of this would take place through an extension action that involved students and employees of the coordination. Conversation circles and meetings were held, the results of which generated four extension actions that demonstrated the importance that the extension practice can represent in enabling the student's contact with the social reality, as well as the need for integration between teaching, research and extension to enable the teaching workload in extension actions.

De-ethnicizing Ethiopian higher education leadership: the quest for merit-based governance

Background This study examines the growing trend of ethnicized leadership in Ethiopian higher education institutions and advocates for a shift toward merit-based governance to improve institutional integrity and performance. Since 1991, with the introduction of ethnic federalism, leadership appointments in Ethiopian universities have increasingly been based on ethnic identity rather than qualifications. This has led to governance challenges, weakened academic standards, and reduced institutional efficiency. The study highlights the need for governance reforms prioritizing meritocracy to enhance the quality and sustainability of Ethiopia’s ethnically diverse higher education system. Methods The study utilizes a qualitative research approach, combining both primary and secondary data. Primary data were collected through semi-structured interviews with university administrators, faculty, and governance experts, while secondary data were gathered from institutional reports, government policies, and academic literature. Institutional theory, principal-agent theory, and meritocratic theory frame the analysis, providing insights into how ethnic-based leadership appointments affect university governance and performance. Results The findings reveal that ethnicized leadership has eroded governance structures, lowered academic quality, and compromised institutional efficiency. Leadership appointments based on ethnicity rather than merit have led to poor decision-making, weakened accountability, and reduced transparency. In contrast, merit-based governance improves accountability, decision-making, and institutional performance. The study emphasizes that transitioning to a meritocratic leadership model is vital for restoring institutional integrity and academic excellence in Ethiopian universities. Conclusions Ethnic federalism, while initially designed to empower regions, has politicized federal institutions, including universities, reducing them to regional entities rather than national institutions. This system of ethnicized leadership has fostered a culture of favoritism, rampant corruption, and ineffective governance, ultimately weakening Ethiopia’s higher education system. Recommendations Governance reforms that prioritize merit-based appointments are urgently needed. Legal reforms, transparent leadership selection processes, depoliticization efforts, and capacity-building initiatives are recommended to foster a meritocratic culture and improve institutional performance in Ethiopian universities.

Originality/Value The research highlights the importance of training professionals with critical and practical skills in CE, highlighting the need for curricular reform that meets new market demands and promotes a circular mindset.

EDUCAÇÃO FINANCEIRA NA EDUCAÇÃO PROFISSIONAL E TECNOLÓGICA

Strictly speaking, capitalism is a cyclical system that alternates cycles of economic growth followed by declines in activities. This magnifies social vulnerability and contributes to the indebtedness of Brazilian families, making Financial Education an urgent and necessary demand. Within the school context, the integration of Financial Education into the integrated curricula of the Federal Network of Professional, Scientific, and Technological Education contributes to the formation of more conscious, critical individuals capable of dealing with the economic and financial challenges of contemporary times. In light of the foregoing, this study aimed to ascertain the perception of graduates from the Integrated Technical Course in Accounting at the Patrocínio Campus of the Federal Institute of Triângulo Mineiro - IFTM regarding the teaching of Financial Education in schools. To do so, it relied on a qualitative methodological approach through bibliographic analysis and questionnaire application. The data indicate that graduates from the Integrated Technical Course in Accounting at the Patrocínio Campus of IFTM consider the topic relevant and even suggest a mandatory and separate discipline to address it in more detail. They also recommend that facilitating the learning of Financial Education topics occur, among other pedagogical practices, through videos. The results obtained stimulate discussion about the importance of integrating Financial Education into educational institutions, especially those offering Professional, Scientific, and Technological Education, thus contributing to the holistic formation of individuals.

Scientific knowledge management in Brazil: an analysis of the Lattes Platform

The Lattes Platform (PL) is an essential resource for Brazil's scientific and technological landscape, centralizing researchers' curricular information and facilitating the management of scientific data. However, the lack of rigorous standardization in the data entered compromises the efficiency of retrieving and analyzing this information, limiting academic knowledge management. This study investigated the limitations of the PL and proposed a solution that integrates new technologies to optimize scientific data management. The research was conducted in two main stages: a systematic literature review on knowledge management and technologies applied to the PL, and a case study at the Federal Institute of Acre (IFAC). The review included the analysis of 79 articles and a survey of software records at the National Institute of Industrial Property (INPI). In the case study, semi-structured questionnaires were administered to IFAC staff to understand their needs and perceptions regarding the PL. The results reveal a significant demand for tools that automate data extraction and integrate the PL with other academic management systems. The analysis of software records at INPI highlighted solutions that can enhance the PL’s efficiency. The integration of Artificial Intelligence (AI), exemplified by the proposed LattesAI, emerges as a promising solution to overcome the platform's current limitations, automating processes and personalizing knowledge management. This innovation not only optimizes academic management but also strengthens Brazil's position in the global scientific landscape, promoting greater efficiency and collaboration in educational and research institutions. Future studies should focus on developing AI algorithms specifically for the PL, ensuring its continuous evolution in response to the demands of the academic environment.

Microphysiological systems to advance human pathophysiology and translational medicine.

Microphysiological systems (MPS) or "organ-on-a-chip" models are sophisticated tools that harness techniques from cell biology, tissue engineering, and microengineering to recapitulate human physiology. Typically, MPS are biofabricated three-dimensional (3-D) tissue constructs integrated into platforms designed to mimic the tissue microenvironment and provide functional outputs. Over the past decade, researchers have endeavored to manufacture high-throughput, high-fidelity MPS models of all major human organs. By incorporating patient-derived cells, researchers have produced biomimetic models of tissues with disease-linked genetic mutations capable of exhibiting patient heterogeneity. This work has demonstrated that MPS more closely model organotypic function and pathophysiology than traditional two-dimensional (2-D) culture systems. Moreover, investigators have shown that human MPS are better predictors of drug efficacy and toxicity than animal models. Thus, MPS have emerged as a promising candidate to improve the efficacy and safety of preclinical trials. In this mini-review, we provide an overview of current advances in MPS models, their applications in mechanistic research, and relevance to drug screening. Finally, we discuss current investments in MPS development by the United States federal government and research institutions around the world to advance translational medicine.

Sociodemographic, economic, and academic factors linked with resilience in university students during covid-19 pandemic: a Brazilian cross-sectional study

BackgroundResilience is a crucial factor in students’ mental health, playing an important role in their successful adaptation to the academic environment. However, there is a lack of understanding about resilience and its associated factors in students from different undergraduate courses. This study aimed to describe the resilience profile of undergraduate students from various courses in Brazil and identify sociodemographic, economic, and academic factors associated with resilience.MethodsThis study has data from a cross-sectional multicenter study involving undergraduate students from eight Federal Institutions of Higher Education in Minas Gerais, Brazil. The dependent variable was resilience, measured using the Connor-Davidson Resilience Scale (CD-RISC) 10-item version, with sociodemographic, economic, and academic factors considered independent variables. Data was collected virtually via a self-administered questionnaire between October 2021 and February 2022 (during the covid-19 pandemic). Independent samples t-tests and ANOVAs were conducted to compare resilience scores between independent variables, and Tukey’s post-hoc test was performed when necessary. Multiple linear regression was performed to create three models.Results8,650 undergraduate students were included in this study. The average score on the resilience scale was 19.86 ± 8.15, with a normal distribution. The respondents ranged from 18 to 71 years old, averaging 23.9 ± 6.33. Being female, not having a religious belief, having low per capita family income, having had a decrease in the family income, not being heterosexual, or having the head of the family with a low education level were the main factors associated, individually, with low resilience scores in the sociodemographic and economic multiple linear regression model constructed. Being from linguistics, letters and arts courses, being enrolled in fewer subjects, or being from UFMG were the main factors associated, individually, with low resilience scores in the academic multiple linear regression model constructed.ConclusionsThe study’s findings revealed that sociodemographic, economic, and academic variables were significantly associated with resilience scores in undergraduates from Minas Gerais during the covid-19 pandemic. These findings can help universities develop target strategies to promote students’ resilience and reduce the risk of poor mental health among this population.

Approaches to Study Politics and Political Systems

This article aims to provide basic concepts regarding different methods of studing political science and system. For this, the author employed descriptive as well as analytical data analysis approaches. The author used secondary sources of information, often known as the desk work approach, while providing this piece of writing. According to the study, traditional approaches to studying politics and political science include philosophical, historical, and institutional approaches, while modern approaches include sociological, economic, psychological, quantitative, simulation, system, behavioral, and Marxian approaches. However, the author briefly examines some of the traditional and modern approaches to studying political science and politics. The Traditional Approach defines Political Science as the study of state, federal, and national institutions. It investigates the formal, legal, and theoretical issues. The Modern Approach focuses on “what is actually happening in the state”. It emphasized reality and facts about politics. In this regard, the article focuses on the fundamental concepts of both methods to studying politics and political science.

The Organizational Image of The Federal Institute of Maranhão: A Study From The Students’ Perspective

Objective: The objective of this study is to compare the attributes that influence the organizational image perceived by freshmen and senior students of the same educational institution. Theoretical Framework: The study of the organizational image within educational institutions is of fundamental importance to guarantee quality teaching. Education must be something tangible and a right for everyone. Therefore, it is important to have this right to quality education assured. Based on studies by Santos (2016), a structured questionnaire was adapted into 39 (thirty-nine) questions. Method: We opted for a quantitative methodology, with a descriptive and cross-sectional character. Primary data collection was adopted through in-person application of questionnaires. Results and Discussion: The data confirm the hypothesis that the organizational image of freshmen is more optimistic than that of veterans. On average, IFMA students tend to be more discerning. It is suggested that freshmen enter the institution with a formed idea and that over time they tend to change. As a limitation, it is mentioned that responses from 9 campuses in the state of Maranhão were analyzed. However, there are a total of 29 campuses spread across the state. An analysis could be carried out in more institutions in order to obtain more general results of the organizational image at the IFMA institution in a larger portion of institutions in Maranhão. Research Implications: As a practical contribution, the results obtained in this study can provide organizations involved with educational institutions with a holistic view of the traits of a good organizational image, awakening new learning interests in students towards the institution. Originality/Value: This research contributes to scientific literature by advancing themes relating to quality management, organizational image, organizational image in educational institutions and public management
