Textural Analysis for Medicinal Plants Identification Using Log Gabor Filters

Texture plays a crucial role in computer vision, providing valuable information about image regions. Log Gabor filters that mimic the human eye's visual cortex are used as feature extractors to identify medicinal plants based on the leaf textural features. This method was tested on a dataset developed from the Centre of Plant Medicine Research, Ghana, consisting of forty-nine (49) plant species as well as the Flavia and Swedish Leaf datasets, which are benchmark datasets. The Log Gabor filter outperformed the Gabor filters, which have been extensively used in this area when tested on nine supervised classifiers (K-Nearest Neighbour, Support Vector Machine, Na�ve Bayes, Logistic Regression, Decision tree, Random Forest, Multilayer Perceptron, Gradient Boosting and Stochastic Gradient Descent) with 10-fold cross-validation. The Support Vector Machine and Multilayer Perceptron were the best performing classifiers for both Log Gabor filter and Gabor filter in terms of accuracy, precision, true positive rate, F1 score and false positive rate. The Log Gabor filter's highest accuracy was 79% for Mydatastet, 97% for Flavia, and 98% for the Swedish Leaf dataset whiles the Gabor filter's highest accuracy was 66% for Mydatastet, 92% for Flavia and 96% for the Swedish Leaf dataset. � 2013 IEEE.

The theatre of Mohammed Ben-Abdallah frames of ritual, faction and postcoloniality

The study was explicitly on the theatre of Mohammed Ben-Abdallah, a Ghanaian theatre personality. He is a dramatist, playwright, educator, and political activist. The study focused on how ritual, faction (fact and fiction), and postcolonial agenda are represented in the selected plays of the playwright. The purpose of the study was to interpret and analyse the adaptations of ritual and faction, which paves the way for a discourse on postcoloniality as composed by Abdallah through his theatre. It was argued that Mohammed ben-Abdallah’s theatre portrays ritual and faction as its mine of knowledge. However, it appears that the array of scholarship relating to the dramaturgical functions of ritual and faction as symbols in interpreting social reality is not evident. The study sought to open new frontiers in Abdallah’s theatre by delving into these elements through the lenses of ritual theory and post-colonial theory. The study used textual analysis as its methodology to venture into an exploration of the historical, cultural, political, religious, and social reality and context of the selected plays. The chosen plays were Song of the Pharoah (2022); The Slaves (2011); The Fall of Kumbi (2010); and The Trial of Mallam Ilya (2008). The plays are uniquely linked by the cord of history, which is the armature. In them are extraordinary cosmos carved in the complexity and multiplicity of ideas, notions, and the total theatre experiences of the proclivities of the essence of the people’s identity and livelihood, which to a large extent have gone extinct, remained dormant, or failed to rekindle. The study revealed that the principal aim of Abdallah is to foster a broader comprehension and admiration for history among a diverse group of people. It was then concluded that Mohammed ben-Abdallah is a prominent historian in motion, utilising his plays to provide insights into the roles and significance of memory for Africans.

Thematic and aesthetic analysis of Dagaaba wellerisms

Wellerisms as variants of proverbs in African oral literature have gained much attention and have been explored by scholars in many languages of the African society. Wellerism proverbs are said to be a common and interesting phenomenon in African languages, claimed to be the preserve of collective traditional wisdom of the community. That is, they are attributed to the wisdom of the elders of the community. Just like a normal proverb does, the wellerism is said to be a powerful tool of University of Education,Winneba http://ir.uew.edu.gh xii communication; they are basically infused in discourse by speakers. Proverbs serve as salt, flavouring the speeches of a speech community. In this study therefore, we examined some themes and aesthetic qualities of the Dagaaba wellerisms which have been least studied. We discussed the meaning and concept of proverbs and wellerisms, as well as the roles and authorship of proverb. The characteristics of Dagaaba wellerisms are delineated. We also examined the sentential structure and some thematic classifications of Dagaaba wellerism proverbs. Also, the aesthetic qualities associated with the use of wellerisms among the Dagaaba are unveiled. It is evident in the study that wellerisms form an integral part of the Dagaaba culture. That is, they are used in their day-to-day communication, not merely for pleasure or to entertain, but to reflect and contribute to their way of life, which form a strong basis for community ties.

Theme in selected congregation speeches of the university of education, Winneba

The study examines the use of language in institutional discourse by discussing the types of Theme used in three selected Congregation speeches of the University of Education, Winneba, the experiential functions Theme manifests as well as the communicative roles it establishes. Using the concept of the clause as message in the Systemic Functional Grammar theory by Halliday and Matthiessen (2014) the findings of the study indicate that the most frequent types of Theme are the Topical Themes which present the core content of the message by indicating participants in the process (action), circumstantial factors in the process as well as the process itself. The results of the study indicate that knowing the direction/angle from which a speaker makes the focus/core of a message is of importance in the understanding of the message through Theme. Theme also facilitates cohesion and coherence in texts. As indicated by Brown &Yule (1983), thematic development is important because University of Education, Winneba http://ir.uew.edu.gh xii what appears in the initial position in a text influences the understanding of everything that comes afterwards, and this is confirmed by the study.

�These religions are no good�they�re nothing but idol worship�: mis/representation of religion in Religious Education at school in Malawi and Ghana

This article draws data from two complementary studies in sub-Saharan Africa to highlight the problem of religious misrepresentation in (multi-faith) Religious Education (RE) at school in Malawi and Ghana. Employing Michael Apples� conception of selective tradition, the article is critical of the confrontational disputation inherent in the RE in the two countries. The misrepresentation is analysed under themes related to classroom discourse and the nature of religion. It argues that RE could actually be counter-productive and thus end up misrepresenting religions instead of promoting them. Unless there is a radical shift in the areas identified, the subject will continue to present a distorted picture of religion and thus fail in its civic responsibility as a curriculum area that is perhaps best placed to inculcate pro-social values towards citizenship in a world of religious diversity. � 2017, � 2017 Christian Education.

A thesis in the Department of Mathematics Education, Faculty of Science Education, submitted to the School of Graduate Studies in partial fulfilment of the requirements for the award of the degree of Master of Philosophy (Mathematics Education) in the University of Education, Winneba SEPTEMBER, 2021

This study explored the school-based factors that contribute to Senior High School (SHS) students‟ performance in core mathematics in Tamale metropolis in the northern region, Ghana. It examined teacher‟s academic qualification and teaching experiences in mathematics, availability of teaching and learning resources in relation to mathematics and other subjects, students‟ interest and attitude towards the learning of mathematics and the extent to which school administration influence students‟ learning through inspection and policies, and how these affect performances in mathematics at examinations. In all, 338 SHS Form 3 students, 30 mathematics teachers and 4 heads of SHSs from four schools were involved in this study. The study used both quantitative and qualitative approach, using interviews, mathematics achievement test and well-structured questionnaire. Descriptive statistics, binary logistics and thematic approach, were used in data analysis. The major findings were related mostly to student‟s interest and attitude towards the learning of mathematics, as some of the students were found spending more time on other things than learning mathematics. For the null model, the output revealed a correct overall percentage of prediction as 91%. From the model with all predictors the p – value was less than 0.05, which means the model was statistically significant which helped significantly increased ability to predict the decisions made by the subject. Therefore, the data fit the model well in the Hosmer-Lemeshow tests of the null hypothesis. Apart from these factors, also teaching and learning resources were a problem; mathematics textbooks were not readily available for students use. On top of these, few classrooms were readily available for students use; there were no classrooms for some classes thereby compelling the authority to collapse two classes into one. However, most teachers have the academic qualification to teach at their respective schools, they lacked seminars and in-service training. These added to lack of intrinsic motivation among teachers. The study recommended several remedies for that situation.

Three Delays Model applied to prevention of unsafe abortion in Ghana: A qualitative study

Background Unsafe abortion is an important public health problem in Ghana, making significant contributions to the morbidity and mortality of reproductive-aged women. Although mostly used in explaining mortality associated with perinatal care, recent calls for research on induced abortion in Africa suggest that the Three Delays Model could be used to enhance understanding of women's experiences and access to induced abortion care. Methods We conducted 47 face-to-face interviews with women who had experienced unsafe abortions, with formal abortion providers (abortion providers in hospitals) and with informal and non-legal abortion providers (pharmacy workers and herb sellers). Study participants were recruited from selected hospitals, community pharmacies and markets within the Ashanti region of Ghana. We drew on phenomenology to analyse the data. Findings The first delay (in seeking care) occurred because of women's poor knowledge of pregnancy, the influence of religion, and as a result of women underestimating the seriousness of abortion complications. Factors including cost, provider attitudes, stigma, and the proximity of pharmacies to women's homes delayed their access to safe abortion and resulted in their experience of the second delay (in reaching a healthcare facility). The third delay (in receiving appropriate care) was a result of hospitals' non-prioritisation of abortion complications and a shortage of equipment, resulting in long hospital waiting times before treatment. Conclusion This study has shown the value of the Three Delays Model in illustrating women's experiences of unsafe abortions and ways of preventing the first, second and third delays in their access to care. � Author(s) (or their employer(s)) 2022.

Time management practices among sandwich students

This study was conducted to investigate time management practices among sandwich students of the University of Education, Winneba. Two theories, Pareto 80/20 rule theory and Theory of Assertiveness supported the study. Through a cross-sectional survey method, the study used a quantitative approach to look into this phenomenon. Simple random sampling technique (specifically lottery (yes/no) method) was used to sample three hundred and fifty-one (351) undergraduate sandwich students from the University of Education, Winneba. Data were collected through the use of questionnaire. Data collected for the study were analysed using SPSS version 22 under frequency tables, mean and standard deviation statistical tools. The study revealed that knowledge the respondents had about time influence their time management practices. Again, the study revealed that respondents faced challenges such as not being able to meet deadlines and stress. It also came out that the respondents adopted strategies such as scheduling tasks appropriately, setting priorities, taking break between tasks to manage their challenges. Results of the study indicated that sandwich students plan the time they spend on various activities on campus. The result proved the hypothesis that there is a significant relationship between students’ knowledge about time and time management practices in the University of Education, Winneba. The study recommends time management as a general course for students or workshop on time management to be organized for students in order for them to effectively balance the amount of time set aside for both personal and academic interests since it will lead to the attainment of goals.

Time management practices among teachers at Adventist senior high school Kumasi in the Kumasi Metropolis

The study sought to find out how teachers manage instructional time at Adventist Senior High School in Kumasi. The main objectives of the study were to find out the effectiveness of teachers instructional time management at Adventist Senior High School, assess the challenges teachers face in managing instructional hours at Adventist Senior High School, and suggest strategies that could be adopted by the teachers to improve the use of instructional hours at Adventist Senior High in the Kumasi. Three research questions were posed to serve as directive to the researcher. Descriptive survey design was employed for the study. The study involved the teaching staff of Adventist Senior High School in the Kumasi Metropolis. A sample size of 108 teachers was used. A simple random sampling technique was used to select the teachers. Questionnaire was the main instrument used to collect data. The instrument was pretested for reliability and validity. Data gathered were analysed and interpreted using SPSS version 20.0. The findings revealed that teachers regularly planned time ahead of instructional hours. It further revealed that obstruction during contact hours, not adhering to the time table strictly due to administrative factors, interruption through co-curricular activities are some challenges associated with managing instructional hours. It was therefore recommended that the head should make it a policy that all meetings should be done after instructional hours to prevent interruptions on instructional hours. Strict adherence to the time table should be insisted on by the head, more teachers should be employed to reduce the work load of existing teachers, and the school administrators should regularly monitor teachers in class during instructional hours.

Toilet chemical additives and their effect on faecal sludge characteristics

This study investigated the effects of two mostly improvised chemical additives, calcium carbide and lambda super 2.5 EC (LSEC), on the physico�chemical and microbial characteristics of faecal sludge from toilets. The quality of faecal sludge was assessed before and after application of the chemical additives in an experimental setup of ten different treatment units including a control, and treatment replicates. The initial characteristic of the faecal sludge was slightly acidic with high content of slowly degradable organic matter. The experimental control without additives after 30 days showed reduction in BOD5, COD, helminth eggs and sludge mass by a maximum of 30%, 34.7%, 99.8% and 55% respectively. Similarly, calcium carbide additive reduced the BOD5, COD, helminth eggs and the mass of the faecal sludge by 47.4%, 48.3%, 99.6% and 61% respectively. Also, LSEC additive reduced BOD5, COD, helminth eggs and the mass of the sludge by 40.6%, 47.9%, 95.9% and 58% respectively. The two additives showed significant treatment effect on the faecal sludge although the level of treatment could not meet the regulatory discharge limits for the key quality parameters assessed including sanitisation. The study is still a grey area and more research is recommended to enrich the findings. � 2020 The Author(s)Environmental engineering; Environmental health; Environmental management; Environmental pollution; Microbiology; Public health; Calcium carbide; Lambda-cyhalothrin; Faecal sludge; Toilet additive; Characterisation; Mass loss; Sanitisation; Public toilet; Biodegradation; Helminth eggs. � 2020 The Author(s)

Toilets for tenants: a cooperative approach to sanitation bye-law enforcement in Ga West, Accra

Many cities have bye-laws that require landlords to provide acceptable sanitation for tenants. Yet landlords fail to provide these facilities and the bye-laws are seldom enforced. This paper provides evidence from low-income urban communities in the Ga West Municipality of Accra, Ghana on the barriers to both toilet provision and bye-law enforcement, drawing on household surveys with landlords and tenants, focus group discussions, and key informant interviews. The key constraints to household toilet construction were found to be the lack of capital, limited space, and availability of nearby public toilets. Barriers to bye-law enforcement included the lack of both financial resources and incentives for the regulator. A simple negotiation game involving landlords, tenants and the regulator was organized, and the agreements reached were used to design a cooperative approach to bye-law enforcement for toilet construction. � 2018 International Institute for Environment and Development (IIED).
