  • Domination of Pollutant Residues Among Food Products of South-East Asian Countries

    Southeast Asia is a region that produces high amounts of key food commodities and includes areas of divergent socio-economic status. Food security is a high-priority issue for sustainable global development both quantitatively and qualitatively. In recent decades, adverse effects of unexpected contaminants on crop quality have threatened both food security and human health. Public concern about the adverse environmental and human health impacts of organochlorine contaminants led to strict regulations on their use in developed nations two decades ago. Nevertheless, DDT and several other organochlorine insecticides are still being used for agriculture and public health programs in developing countries in Asia and the South Pacific. As a consequence, humans in this region are exposed to greater dietary levels of organochlorines. Heavy metals and metalloids (e.g., Hg, As, Pb, Cd, and Cr) can jeopardize human metabolomics, contributing to morbidity and even mortality. Those during crop production include soil nutrient depletion, water depletion, soil and water contamination, and pest resistance/outbreaks and the emergence of new pests and diseases.

  • Analysis of Gender Representation of Grade Eight English Textbook

    The purpose of this study was to investigate and analyze gender representation in Grade Eight English textbook. For this purpose, all the units of Grade Eight English textbook were thoroughly investigated. The content analysis method was employed. The results revealed that there is no fair representation of females and males in some gender related characteristics. The supremacy of males over females was observed in terms of names (54.77%) male and pronouns (52.97%) male were observed and it was suggested that reconsideration should be made in revising and/or producing new textbooks in the future.

  • Assessing the Practices and Challenges of Guidance and Counselling Services in Secondary Schools of Gondar City Administration

    The main purpose of the study is to assess the practices and challenges of guidance and counselling services of secondary schools in Gondar town. The study used mixed research approaches based on which a descriptive design was followed. Both primary and secondary sources of data were used. The primary sources of data to the study were the research participants (students, principals, counsellors and a supervisor). The secondary sources of data were collected from different literatures related to the problem. In this study, only government secondary schools were included using purposive sampling technique based on the researcher’s own determination. The study focused on full cycle secondary schools that provided education from grade 9 – 12 and they were selected using purposive sampling technique. There were six government full cycle secondary schools of which the study took 3 (50%) using purposive sampling technique with the number of students they served as the major criteria of selection. The total population of the study encompassed grade 9 – 12 students, counsellors, principals and supervisor. For this study 369 samples were selected of which 362 were students; 3 were principals; 3 were counsellors and 1 was a supervisor. Data were gathered using questionnaires and focus group discussion from students and interviews from principals, counsellors and a supervisor. The collected quantitative data were first edited, organized in tables and analyzed using frequency count (numbers), percentage, mean score and standard deviation. The qualitative data were thematically analysed in accordance with the quantitative results of the study. Based on analysis of the results, it is concluded that guidance and counselling services were not promising and adequately provided in the schools although counsellors were assigned. Counsellors’ roles were insufficient to serve the students as a result of which students’ perception towards the services was negatively expressed. Generally, guidance and…
