Frequent consumption of aflatoxins-contaminated spices has been linked to serious adverse health effects among consumers. The likelihood of exposure to these toxins is influenced by the level of public awareness. Controlling aflatoxins contamination throughout the food chain is critical for public health. This study aimed to assess the handling practices and awareness of aflatoxin contamination among micro- and small-scale spice processors. A total of 60 processors from 4 districts of two regions of Tanzania were interviewed. The results showed that while 56.7% of interviewed processors were aware of aflatoxin contamination in spices primarily through training (38.3%) and mass media (30%). However, there were still misconceptions regarding the causes and effects of aflatoxins to human health. It was observed that, poor drying and storage practices, inadequate monitoring of processors aggravated the situation. Nonetheless, all interviewed processors expressed willingness to participate in training programs to ensure quality and safety along the chain. The study findings underscore the necessity for targeted interventions to reduce aflatoxin risks in the spice value chain. These should include strengthened food safety inspections and enforcement, as well as tailored training and support for micro and small-scale spice processors. Enhancing their knowledge and ability to adopt proper handling, drying and storage practices is critical for enhancing food safety and safeguarding public health.

The theme of the study that catches our attention is the initial conceptions of learners in Science and school performance; this theme is based on the competency-based approach in force in Cameroon, which is implemented in several African countries. Insofar as learning is not the accumulation of new knowledge but a cognitive reorganization of old knowledge experienced, it is therefore a question of knowing what is the influence of initial conceptions on the academic performance of learners in science. The objective of this research was to show that taking into account the initial conceptions of learners, Biology “SVT” has a lasting influence on learning and thus on the academic performance of learners. To achieve this objective, the study uses the mixed and quasi-experimental method, where two groups of learners were used: a control group and an experimental group. The experimental group was subjected to the teaching-learning system designed for this purpose, and in which the initial conceptions of the learners were taken into account according to do with or go against. In the light of the different hypotheses adopted and the different results of this study, it can be observed that the didactic consideration of the learners' initial conceptions improves their academic performance through the data of the experimental group. In relation to the field of education, this study shows that in order to enable learners to learn and build knowledge in the long term, their initial conceptions must be taken into account in concrete didactics; Otherwise, learning will be sporadic, learners' conceptions will be significant, which will lead to a learning defect perceptible by school failure.

This paper investigates the constructability of angles multiples of 3 within the framework of Euclidean geometry. It makes a significant contribution by presenting the first geometric construction for all such angles, offering a rigorous solution to a longstanding geometric problem. The paper reaffirms the efficacy of Euclidean geometry in providing precise constructions and robust proofs for these angles, demonstrating the enduring strength of Euclidean principles from classical to modern times. The presented workflow goes beyond Euclidean geometry to examine non-Euclidean methods, particularly analytical approaches, revealing misconceptions that compromise the genetic and geometric rigor of Euclidean principles. The paper exposes incongruities when algebraic proofs related to angle constructability are applied to the Euclidean system, emphasizing the misalignment of fundamental geometric concepts. A notable result in the paper is the construction of a angle, introducing the “ angle chord” as a novel geometric property. This property challenges assumptions made by non-Euclidean methods and highlights the nuanced geometric properties crucial for rigorous constructions. The paper refutes the fallacy of relying solely on algebra for solutions to angles multiples of , emphasizing the necessity of embracing Euclidean geometry for geometric discoveries. The paper underscores the merits and resilience of Euclidean geometry, showcasing its independence and depth across historical and modern perspectives. The newly presented geometric construction not only resolves a longstanding question but also emphasizes the intrinsic strength and uniqueness of Euclidean principles in contrast to alternative methodologies.

Background: Electronic cigarette (e-cigarette) use and vaping tobacco have increased rapidly worldwide, raising concerns about their health effects, social acceptability, and regulatory challenges. In many countries, e-cigarettes are more commonly used by individuals from higher socioeconomic status (SES) backgrounds, who, in theory, should have greater knowledge about e-cigarettes and their associated risks. However, it remains unclear why a group with more knowledge about e-cigarette risks would also hold more positive attitudes toward vaping and exhibit higher usage rates — a phenomenon that may represent a knowledge-behavior paradox. Understanding this paradox, along with the complex relationships between e-cigarette knowledge, attitudes, and behaviors, is critical for informing effective public health interventions, campaigns, social media messaging, and regulatory policies. Objectives: This study aimed to evaluate the complex relationship between SES, e-cigarette knowledge, pro-vaping attitudes, and e-cigarette use. Methods: The SMOKES Study (Study of Measurement of Knowledge and Examination of Support for Tobacco Control Policies) used a multi-center, cross-sectional design, collecting data from 2,403 college and university students across 15 provinces in Iran (covering nearly half of the country's provinces). The survey measured family income, age, sex, ethnicity, e-cigarette use, knowledge, and attitudes. Structural Equation Modeling (SEM) was employed to examine the interrelations between SES, knowledge, attitudes, and behavior, while adjusting for age, sex, and ethnic minority status. Results: SEM analysis confirmed the hypothesized paradox. Although greater knowledge about e-cigarettes was linked to less favorable attitudes toward vaping and lower use, pro-vaping attitudes emerged as the strongest predictor of vaping behavior, while knowledge played a weaker protective role. Notably, individuals with higher SES simultaneously showed higher knowledge and, paradoxically, more pro-e-cigarette attitudes and greater usage. Female students and ethnic minority students reported higher correct knowledge and lower pro-vaping attitudes and use. Although age and higher family income were associated with more favorable attitudes, they did not directly predict vaping behavior. These results suggest that for higher SES individuals, poor knowledge is not the main driver of e-cigarette use; rather, their pro-e-cigarette attitudes, which seem to outweigh the influence of knowledge, play a key role. Conclusions: Although individuals from higher SES backgrounds report greater correct knowledge about e-cigarettes, this knowledge does not necessarily translate into reduced positive attitudes or lower usage. This study highlights the complexity of these paradoxical effects and suggests that public health strategies need to go beyond simple education and knowledge-based interventions. Targeted approaches should address industry messaging, challenge misconceptions, and strengthen regulatory efforts to reduce e-cigarette use among young adults, including those from higher SES backgrounds.

The study investigated formative assessment conceptions and practices among the teachers of social studies in the Techiman Municipality of the Bono East Region of Ghana. The research was undertaken with the view of finding answers and making suggestions that could help improve the formative assessment practices specifically in social studies. A census was conducted in the eighty-four (84) public Junior High Schools in the Techiman Municipality in the Bono East Region. All the ninety-five (95) Social Studies teachers in the public Junior High Schools in the Municipality were selected for the study. A 50-item questionnaire including 2 open-ended questions was developed for the teachers. The data collected were analysed by using frequencies, percentages, mean and standard deviation. The study revealed that, the teachers had correct conception of formative assessment and saw its relevance in the classroom, however, their assessment practices were not formative enough. The teachers’ assessment practices were influenced by external factors. It is recommended that pressures such as demand for continuous assessment marks to grade students ought to be reduced to allow the teachers practice assessment as professionals.

The purpose of the study was to examine factors associated with low female participation in colleges of education sports. The population of the study was made up of female colleges of education athletes from Central, Western and Western North Regions of Ghana. Purposive and simple random techniques were used to the colleges of education and the respondents for the study. All the all the six colleges of education were purposively sampled and sampling technique was used to select the one hundred and eighty (180) participants who participate in the College of Education Sports Association (CoESA) games and in the Central, Western and Western North Regions of Ghana were used for the study. The main instrument for the study was a self-structured questionnaire (r= 0.92) containing items based on a five-point Likert scale was used for data collection. The data was analyzed using frequencies, percentages and Chi-square test to determine the relationship among the factors. The study revealed that there is the need for college authorities and female coaches in the colleges of education to take care of female athletes and make adequate provision for more modern sports facilities and equipment to sustain their interest in sports participation. The study recommended that, that the coaches should be mindful of their approach to prospective sportswomen. It is also recommended that, various colleges of education should make a concerted effort to organize programmes and seminars regularly to educate females in the colleges on the career benefits of sports participation and iron out their misconceptions.

The purpose of this study was to examine the effects of Subject Conception and Efficacy Beliefs on the Teaching Effectiveness of Social Studies teachers. The study focused on how teachers’ conception of Social Studies affect their sense of efficacy and ultimately their teaching effectiveness. The study adopted a non-experimental descriptive design to achieve its objective. The population for the study comprised of fifty-two (52) JHS Social Studies teachers. In this study the accessible population was the same as the target population. All the fifty-two (52) teachers teaching Social Studies in the Tano South district were used for the study. Purposive sampling technique was used to sample the respondents for the study. The data for the study was collected using the observation guide, questionnaire and teacher sense of efficacy scale adapted from Tschannen-Moran and Hoy, (2001). Mean, percentages, ranges and correlation were used to analyse the data using SPSS. The findings of the study showed that majority of the Social Studies teachers conceived the subject as citizenship education. Teachers’ also rated their sense of efficacy very high. However, the study revealed that most of the Social Studies teachers teaching effectiveness was low. The low teaching effectiveness would affect the realisation of the objectives of Social Studies. Also, there exist low correlation between teacher efficacy and teaching effectiveness as well as subject conception and teaching effectiveness. The correlation between teacher efficacy and effectiveness was weak and as such it is recommended that there should be a concerted effort to update and upgrade teachers’ knowledge with strong pedagogical skills and better understanding of the task of the Social Studies teacher through workshops and short courses.
