Social media platforms like X (formerly Twitter) generate vast volumes of user-generated content that provide real-time insights into public sentiment. Despite the widespread use of traditional machine learning methods, their limitations in capturing contextual nuances in noisy social media text remain a challenge. This study leverages the Sentiment140 dataset, comprising 1.6 million labeled tweets, and develops predictive models for binary sentiment classification using Naive Bayes, Logistic Regression, and the transformer-based BERT model. Experiments were conducted on a balanced subset of 12,000 tweets after comprehensive NLP preprocessing. Evaluation using accuracy, F1-score, and confusion matrices revealed that BERT significantly outperforms traditional models, achieving an accuracy of 89.5% and an F1-score of 0.89 by effectively modeling contextual and semantic nuances. In contrast, Naive Bayes and Logistic Regression demonstrated reasonable but consistently lower performance. To support practical deployment, we introduce SentiFeel, an interactive tool enabling real-time sentiment analysis. While resource constraints limited the dataset size and training epochs, future work will explore full corpus utilization and the inclusion of neutral sentiment classes. These findings underscore the potential of transformer models for enhanced public opinion monitoring, marketing analytics, and policy forecasting.

Objective: The knowledge, attitudes, and practices of SUA students about the use of plastics containing endocrine disruptors were investigated in this study. Methodology: A study with 150 participants was conducted to assess individuals' knowledge about endocrine disruptors, attitudes, and plastic use practices. Results: The findings indicate that the participants possessed an average degree of knowledge 50.2 ± 3.85 with the main emphasis of awareness being generic concepts rather than specific substances. Regarding the potential health impacts of endocrine-disrupting chemicals present in plastics, respondents' attitudes ranged from fair to positive, with a mean score of 3.5 ±0.09 indicating a fair attitude overall. Conclusion: It is important to practice polite behavior and increase public awareness of safe plastic disposal methods. Surprising only 38.0% of the participants mentioned that they refrain from heating their food in plastic containers to reduce their exposure to plastics. Students' practices revealed a notable dependence on plastic products despite their awareness of the concerns surrounding endocrine disruptors, as most of them reported using plastic water bottles, plastic cups, and plastic bags almost always. Additionally, only 20.7% of the respondents consistently implemented strategies to prevent exposure to endocrine-disrupting chemicals. Recommendation: The study recommended increasing the use of cleaner plastic substitutes and improving educational programs to convert information into practical actions. Policies that encourage environmentally friendly behavior and raise public awareness of safe plastic disposal techniques should be put into practice.

The accurate estimation of Individual Wave Components (IWC) is crucial for automated diagnosis of the human digestive system in a clinical setting. However, this process can be challenging due to signal contamination by other signal sources in the body, such as the lungs and heart, as well as environmental noise. To address this issue, various denoising techniques are commonly employed in bowel sound signal processing. While denoising is important, it can increase computational complexity, making it challenging for portable devices. Therefore, signal processing algorithms often require a trade-off between fidelity and computational complexity. This study aims to evaluate an IWC parameter extraction algorithm that was previously developed and reconstruct the IWC without denoising using synthetic and clinical data. To that end, the role of a reliable model in creating synthetic data is paramount. The rigorous testing of the algorithm is limited by the availability of quality and quantity recorded data. To overcome this challenge, a mathematical model has been proposed to generate synthetic bowel sound data that can be used to test new algorithms. The proposed algorithm’s robust performance is evaluated using both synthetic and clinically recorded data. We perform time-frequency analysis of original and reconstructed bowel sound signals in various digestive system states and characterize the performance using Monte Carlo simulation when denoising is not applied. Overall, our study presents a promising algorithm for accurate IWC estimation that can be useful for predicting anomalies in the digestive system.

Risks in Public Private Procurement mass housing project (PPP-MHP) initiatives are emerging and this requires early risk identification and allocation to achieve the goal and sustenance of the scheme. The study, being a follow-up of a Delphi survey, elicits the opinion of respondents on the probability of occurrence and severity of identified risks in PPP-MHPs in Nigeria. The study adopts a quantitative research design approach by administering structure questionnaire survey on identified PPP-MHPs partners in Abuja, Nigeria. Data analysis was performed using descriptive and inferential statistical tools such as Mean item score (MIS), standard deviation, and Kruskal Wallis analytical techniques with the aid of SPSS software packages. The findings show that all the listed risk factors were found to be extremely high, very high, high, or moderate in terms of occurrence while all the listed risk factors recorded a very high level of severity on the delivery of PPP-MHPs. The top ten (10) risk factors frequently associated with PPP-MHPs are non-availability of finance, high finance cost, non-involvement of the host community, poor execution of housing policies, corruption and lack of respect for law, wrong perception of housing need by low-income earners, Illegal title to land, land acquisition and site availability, level of demand for the mass housing projects and unstable value of local currency. The respondents differs significantly on 29 risk factors in terms of occurrence and 40 risk factors in term of severity. The study, therefore, recommends that risk management culture should be highly encouraged among the PPP Partners in the sector. The study intends to enumerate the rate of occurrence of some itemized risk factors and their severities on the delivery of PPP – procured mass housing projects in Nigeria and the need to bookmark these risk factors in ensuring the sustainability of the PPP mass housing scheme.

There have been various concerns about the environmental impact of construction works. This generates a need to take a more proactive approach in evaluating the environmental impacts of construction operations and further explore ways to reduce the environmental impacts. Enormous opportunities exist within the building industry to achieve a reduction in greenhouse gas emissions. The aim of the study is to develop a framework for the evaluation of improvement opportunities for environmental impact for onsite and offsite building construction works using life cycle assessment (LCA) and value-stream-mapping concepts. Various tools for LCA exist; however, there is a need for the development of an LCA framework and improvement opportunities that can be localized to various communities to evaluate improvement opportunities for building construction. This study conducts a review of methods to evaluate the LCA of buildings on local construction sites. A procedure for establishing improvement opportunities is also developed. Based on the author’s knowledge and experience, including site visits, using value stream mapping (VSM) techniques, a conceptual framework of the present state map and future state map of residential construction works was developed. The study presents a procedure for the evaluation of improvement opportunities for the environmental impacts of construction operations.

The building construction industry holds a crucial role in the reduction of greenhouse gas emissions globally. The targets for greenhouse gas emissions may not be achieved without a defined strategic plan to meet up with the set targets from various sectors of the economy. Recognizing the enormous potential that the building industry holds in contributing to global greenhouse gas GHG emission reduction, this study describes a framework on how optimization techniques can be used as a guide for emission reduction targets for the housing sector using illustrations of the onsite and offsite building construction industry. Given that some of the GHG gases are also sources of air pollution, this study includes a discussion on how the effort to address air pollution can be used to find a consensus towards addressing the concern about GHG emissions. This study presents procedures for simplified methods of estimation of GHG emissions that various municipalities around the globe can use to estimate and report the emissions from the building construction industry. The study presents a unifying strategy for emission management. The study also demonstrates how programming methods can be applied to GHG emissions management. The approach used in this study is transferable to other industries. The study recommends a unifying strategy for the management and control of emissions in the building construction industry. The study also recommends a coordinated effort in sharing best practices for emission control and management from all jurisdictions globally. In the effort to reduce global emission targets, further studies like this and its expansion is recommended for all sectors of the global economy. It is recommended that these studies should be followed by a concrete effort to achieve good implementation of sustainable emission reduction targets globally.

Study selection, data extraction, and quality assessment were carried out independently by two reviewers. Due to the heterogeneity of the included studies, a qualitative synthesis was performed. Results: A total of 32 studies were included. Preventive measures identified in the literature comprised combined antibiotic prophylaxis (cefazolin and gentamicin), multimodal perioperative protocols such as ACERTO, nasal decolonization for Staphylococcus aureus, silver-impregnated dressings, and structured post-discharge surveillance. Treatment strategies included DAIR (Debridement, Antibiotics, and Implant Retention), the DAPRI technique, one-stage and two-stage revision surgeries, muscle flap reconstructions, and protocols without spacers. These interventions were associated with significantly reduced infection rates and improved clinical outcomes when applied appropriately and in accordance with patient-specific factors. Conclusion: Effective prevention and treatment of PJI in total hip arthroplasty require a systematic and evidence-based approach. Integrated protocols—spanning preoperative optimization, meticulous intraoperative techniques, and rigorous postoperative monitoring—have proven effective in reducing infection incidence. In cases of established infection, surgical management must be tailored to the timing of infection, microbial profile, and host conditions. Two-stage revision remains the gold standard for complex infections, while one-stage revision and emerging techniques like DAPRI offer promising results in selected cases. This review contributes to the standardization of clinical practice and supports improved patient outcomes.

This study investigated the pedagogical implications of out-of-field teaching in Social Studies. The Out-of-field Social Studies teachers could encounter several challenges in their preparation and the implementation of the integrated Social Studies curriculum. This study sought the lived experiences of the out-of-field teachers concerning the causes of out-of-field teaching in social studies, problems encountered by the out-of-field teachers and the mechanisms they employ to cope with the teaching of Social Studies. The study chose the qualitative phenomenological research design. Data were collected from all the 17 out-of-field Social Studies teachers through in-depth structured interview. Data were transcribed and analysed, through the inductive thematic analysis approach, unveiling of themes and concepts from the narratives of the research participants. The study revealed that out-of-field teaching in Social Studies occurs as a result of teacher shortage in integrated social studies programme. It is also caused by the perception that any teacher could teach Social Studies irrespective of the teachers’ qualification. Out-of-field teacher encounter problems such as inadequate content and pedagogical knowledge, lack of classroom managerial techniques and inability to deliver lessons through the integrated approach. Engaging in professional development courses, peer coaching, in-service training and workshops were some of the mechanisms employed by out-of-field teachers to cope with the teaching of Social Studies. The pedagogical implications of this phenomenon are that when teaching the Social Studies, the out-of-field teachers place more emphasis on aspects of the Social Studies curriculum where they have much knowledge and skip or put less emphasis on other aspects they lack in-depth knowledge, thus, the integrated approach to teaching Social Studies is not adopted effectively by out-of-field teachers. This waters down the content of Social Studies at the Senior High School level. Addressing the problem of out-of-field teaching in Social Studies requires training and recruiting more teachers who have background training and experience in the integrated approach to the teaching of Social Studies.

Stigma surrounding drug addiction remains a critical barrier to effective treatment, significantly influencing healthcare access, patient engagement, and recovery outcomes. This study explores the multifaceted impact of stigma on individuals seeking help for substance use disorders (SUDs), with a focus on healthcare-related discrimination, internalized stigma, and structural barriers. Research indicates that negative perceptions among healthcare providers contribute to delayed treatment-seeking behaviors, reduced adherence to medication-assisted treatment (MAT), and increased relapse rates. Additionally, patients internalizing these societal judgments experience heightened psychological distress, social isolation, and decreased self-efficacy, further hindering their recovery process. To address these challenges, evidence-based strategies such as addiction medicine education, trauma-informed care, harm reduction approaches, and peer support models have been shown to effectively reduce stigma and improve treatment outcomes. Hospital administrators and nursing leaders play a critical role in fostering a culture of empathy, advocating for the reframing of addiction as a neuro-psycho-biological disease rather than a moral failing. Future research should explore digital mental health interventions, motivational interviewing techniques, and interdisciplinary collaboration to further dismantle stigma and enhance the effectiveness of addiction treatment programs. This study highlights the urgent need for systemic policy changes, targeted educational programs, and a shift in clinical attitudes to create a more inclusive and stigma-free healthcare environment. Through implementing these approaches, healthcare providers can ensure equitable access to treatment and improve long-term health outcomes for individuals with opioid use disorder (OUD) and other substance-related conditions.

The anterior collateral ligament (ACL) is one of four ligaments in the knee, connecting the tibia and femur and acting as a key stabilizer. Factors influencing these injuries include playing surface, training programs, athlete strength, technique, and gender. Female athletes are at a higher risk of ACL injuries, being four to nine times more likely than males, often due to differences in biomechanics and training patterns. It ss important that rehab focuses on both legs, as overworking the injured leg increases the risk of injuries elsewhere. Prevention training, such as proprioceptive-balance and plyometric agility training, has been shown effectiveness in minimizing ACL injuries. Despite some limitations in research, these programs highlight the importance of improved training techniques. Kinesio taping might help reduce pain but lacks strong evidence for preventing ACL tears.

The study aimed to examine the availability of protective clothing and its usage among workers at the University of Cape Coast in the central region of Ghana. It used the Accident-Proneness Theory and the Theory of Reasoned Action to achieve the study's objectives. The study adopted the positivist research paradigm. The study used a descriptive design with mixed methods. The study population comprised all workers and supervisors whose work demands the use of protective clothing at the University of Cape Coast. The study used multistage sampling techniques (stratified, purposive, proportional and Systematic random sampling techniques) to select one hundred and ninety-six departmental workers and five (5) supervisors in the University. The main instruments for data collection were a Semi-structured questionnaire and an unstructured interview guide. Mean and standard deviation, frequency count, and percentages were used to analyse the quantitative data. The qualitative data was analysed through the development of data categories and themes. The study concluded that “not all the protective clothing for the various departments were available. The University ensured that workers used what was in stock at the department. The protective clothing supplied to the various departments was insufficient, so their continuous use of the existing ones got them defaced, bringing about shortages. The study also revealed that workers used protective clothing most often, but not all used it because safety laws were relaxed. The study recommended that the University ensure a regular and adequate supply of PPC, insist on its usage, and enforce the use of PPC by all workers whose work demands it.

This study investigated the use of digital design as a tool for assessing attitudes among male sex offenders by exploring how artistic expression can reveal complex emotional landscapes related to their crimes. The study utilized digital paintings, a type of digital design that involves creating artwork using digital tools and software. Digital painting tools allowed the researcher to simulate traditional painting techniques, while benefiting from the flexibility and versatility of digital media. It is essential to comprehend and address offenders’ attitudes towards sexual crimes to create prevention and rehabilitation plans that work. The effectiveness of digital paintings that illustrate the consequences of sexual crimes on offender, victim and the offender’s family was examined in this study. The study examined whether exposure to these visual representations could result in a quantifiable decrease in supporting attitudes toward sexual crimes by comparing participants' pre-test and post-test attitudes using the Crime Pics II tool. There is little research on how visual cues can change offenders' attitudes and perceptions, despite the urgent need for creative evaluation techniques in this delicate field. This study adds to the continuing conversation on crime prevention and offender rehabilitation by demonstrating how well digital design can change perceptions of sexual crimes. A total of 61 male convicts of defilement and rape were purposively sampled for the study. The study utilized an art exhibition and Rapid Serial Visual Presentation format to repeatedly display digital paintings to participants aged 18-45. The artwork produced in both monochrome and polychrome schemes and in realist and surrealist styles was designed to elicit immediate emotional and cognitive responses. Qualitative and quantitative analyses of the participants' responses and reflections provided important insights into their attitudes, including sentiments of regret and guilt as well as a sophisticated awareness of the wider effects of their behaviour. Monochrome paintings tended to portray darker emotions, whereas polychrome paintings showed a wider range of emotions, including hope and recognition of the harm done. The findings demonstrate that digital design can effectively support offenders' emotional processing and self-reflection, demonstrating its potential as a helpful tool in rehabilitative and assessment contexts.

The purpose of the study was to examine the Influence of Physical Features of the Housing Environment on Students' Halls of Residence at the University of Cape Coast in the central region of Ghana. Quantitatively, a descriptive survey research design was adopted for the study. Housing Deficit Theory underpins the study. The study population comprised three hundred and eight one (381) level 100 students in the Halls of Residence at the University of Cape Coast. Stratified proportionate random and simple random sampling techniques were used to select the eight (8) halls of residence and three hundred and eight one (381) level 100 students. The main instrument for data collection was a questionnaire. Cronbach's alpha was used in the study to assess the reliability of the variables. Descriptive statistics were used to analyse the data and show the direction of the responses. The study revealed that the students were satisfied with the physical features of the halls of residence, which influenced their contentment. Features such as recreational facilities, fire service systems, and relaxation facilities were vital in reaching such satisfaction. The study also indicated that the students were satisfied with how much their housing environment influenced their contentment. Students' relationship with their colleagues, the proximity of their halls of residence to the lecture halls and the serenity of the environment of the halls of residence all proved helpful in aligning the students' contentment to such an extent. It is recommended that the hall management should maintain the present physical features and facilities in the halls of residence for students' satisfaction. It is also recommended that the university management take into consideration the proximity of the halls of residence to the lecture theatres and the serenity of the environment of halls of residence in any future halls of residence construction.

This study aimed to examine students' perceptions of the usefulness of formative feedback in mathematics lessons at Sagnerigu Municipality in the Northern Region of Ghana. Quantitatively, this study employed a descriptive non-experimental survey design. The population comprises all pupils of public Junior High Schools in the Sagnerigu Municipality. A purposive sampling technique was used to select the Junior High School students for the study. The criterion purposive sampling technique was used to select 518 final-year students for the 2022 Basic education certificate examination from 14 schools in Sagnerigu Municipality. The chosen schools comprised 291 students from high-performing schools and 227 students from low-performing schools. The primary tool for the study was the Student Feedback Perception Questionnaire (SFPQ), administered to the student participants. The Descriptive statistical tool was used to analyse the mean and standard deviation of the data. The study's examination of students' perceptions of feedback revealed a moderate level of perceived usefulness. This emphasises the importance of feedback as a tool for student growth and development. However, the findings also suggest the need for further support and guidance to optimise the impact of feedback on student learning outcomes. The findings also suggest that students value feedback that helps them improve their skills and strategies in Mathematics and keeps them on track to succeed. It also highlights the importance of providing different types of feedback to cater to the diverse learning needs of students. Educators can create a conducive environment that promotes student engagement and achievement by equipping teachers with effective feedback techniques, emphasising constructive comments and avoiding grades.

This study aimed to explore the relationship between teacher training and challenges in delivering effective sex education in the Sagnarigu district in the Northern region of Ghana. The Social-cultural theory underpins the study. A descriptive survey research design was adopted for the study. The population of this study comprises teachers, head teachers and a School Improvement Support Officer (SiSo) in basic schools in the Gumani/Nyanshegu circuit in the Sagnarigu district of the Northern Region. This study adopted multi-sampling methods to select respondents. Random and purposive sampling techniques were used to select the study's 10 basic schools and 83 respondents. The main tools used for the data collection were the questionnaire and interview. The data was analysed using Statistical Package for Social Scientists (SPSS) software version 23 tools. Descriptive Statistical tools such as frequencies were used to gauge the number of occurrences of the studied variables. The qualitative data was also further analysed in line with the research questions to establish patterns of similarities and variations. These were then validated with the quantitative data for any possible contradictions in the findings. The study concludes that people's socio-cultural and religious beliefs and practices affect the teaching of sex education in school. It was observed that sex education could be misconstrued as an encouragement to young people to engage in early sexual promiscuity. Finally, the study concludes that there cannot be effective sex education without the appropriate logistics such as T.L.M.s, syllabus and time allocation for the subject. The study also acknowledges that the availability of these materials must go along with appropriate capacity building for teachers to be well-positioned to teach the subject. It is recommended that Sexuality education should be included in the curricular and academic calendar of basic schools, along with the provision of adequate T.L.M.s and the proper collaboration with appropriate agencies for the effective teaching of the subject. Sex education needs to be given maximum attention, just as any of the life skills subjects, with adequate investment and motivation to both teachers and pupils to ensure a meaningful impact. There should be regular monitoring, supervision, and assessment of the training of teachers and its influence on the teaching of the subject, as well as ensuring that ethical considerations regarding cultural and religious sensitivities and individual privacy issues are upheld.

This article assesses the realities of sexual harassment (SH) in selected tertiary educational institutions in Ghana. Using multiple data collection techniques, three areas that are related to SH were assessed. These are knowledge of what constitutes SH, the nature and incidence of SH, and strategies/procedures for handling issues of SH in tertiary educational institutions. The findings from the perspective of teaching and non-teaching staff strongly suggest that knowledge of SH was high among teaching staff but low among non-teaching staff. Staff could not relate very well to the reporting systems and procedures of SH in their institutions. Issues of SH were left in the hands of only a few staff while newly recruited staff showed little understanding of the reporting systems and procedures. From the perspective of students, knowledge of what constitutes SH was high. Students were able to indicate the various SH reporting systems/procedures in the tertiary educational institutions and further indicated that the institutions have provided a safe environment and appointed designated people to handle sexual harassment complaints. Surprisingly, the incidence of sexual harassment was low, and this affected sexual harassment reporting.

This aimed to examine the societal perception of new religious movements' televangelism in Dunkwa-On-Offin, Ghana's Central Region. The study used a sequential explanatory mixed-methods design, using the mixed methods approach to research. The population of this study comprised Women, Regular churchgoers, believers, and those listening to televangelism services by new religious movements, as well as clergy, lay leaders, and other male worshippers. Random and purposive sampling techniques were used to select 200 women and 20 men from House of Power Ministry International and GILGAL Pentecostal Prayer Ministry International as the respondents for the study. The instruments used for data collection were questionnaires and interview guides. IBM SPSS statistics software version 23 was used to analyse the quantitative data, while qualitative data was analysed thematically with an interpretative lens. The study has revealed that society perceives the televangelism movements as helpful and encouraging but could also create trouble in fundamental Christian worship principles. The study also indicates that televangelists emphasise material things rather than spiritual matters. Other concerns included that televangelism brings about the separation of family and friends because they always inform members that their friends and family are evil. It is recommended that there is the need to change or improve the credibility perception among Christians in Ghana about televangelism. Televangelists must exhibit accountability and integrity to their worshippers by providing adequate information to encourage viewers to support their ministries.

Good academic writing requires a good combination of cohesive ties and coherent features in the text. This study aimed to assess whether paragraph unity and coherence in writing were achieved among students of the Komenda College of Education concerning gender. Lakoff’s Theory underpinned the study. The quantitative approach and a descriptive research design were used in the study. The sample size was 60 (40 males and 20 females). Level 200 students from the Komenda College of Education Department of English were selected using census techniques. The instruments used for data collection were text items and questionnaires. Paragraphs written by the students were analysed using narratives, and quantitative data was analysed using mean, standard deviation and the independent samples t-test. The study revealed that male students have a higher mean score than female students. The study also concluded that there was no significant difference between male and female students regarding achieving paragraph unity and coherence in writing. In other words, gender does not influence how paragraph unity and coherence are achieved in writing – males and females are statistically the same. It is recommended that the principals of the various colleges of education in Ghana encourage the college tutors and the Student Representative Council (SRC) leadership to introduce a programme which engages college students in competitive writing without gender barriers. This programme will ensure that students compete by writing academic papers, demonstrating their knowledge of achieving unity and coherence in writing. This programme can be done every academic year, and an equal number of males and females are presented yearly.

Qualitatively, the study adopted a case research design. The population of this study comprised the last batch of Diploma in Basic Education (DBE) and the current first-year students of the new programme (Bachelor in Basic Education) of Mount Mary College of Education. Simple random and stratified sampling techniques were used to select 15 long essays from the final year, while 30 assignments were chosen from the first year. Nine (9) long essays from the English language, five (5) essays from Social Studies and one (1) essay from Mathematics. The main tools used for the study were students' assignment items and copies of long essays. Through an interpretative lens, the data were analysed into themes. The data and the analysis largely showed that students employed different kinds of modal verbs in their writing, including complete and periphrastic modal verbs. There was evidence that students have used these modal verbs in different ways that sometimes affected the intended meaning. These inappropriate choices are evident in both written texts and oral presentations. Findings showed that students employed modal verbs indiscriminately with little attention to contexts. It would be recommended that language teachers deal with the issue by giving written feedback on the use of modal verbs to students in their texts anytime they are given assignments.

Groundwater is undeniably crucial to people's lives, particularly in coastal regions. Therefore, it is imperative to address this vital water source strategically and implement a management plan to maintain its optimal state. The salinization of groundwater poses a significant challenge for coastal communities, stemming from factors like excessive groundwater extraction from coastal aquifers, reduced recharge, rising sea levels, climate change, and other causes. Saltwater intrusion (SWI) is a prevalent issue that needs attention, as it significantly threatens groundwater quantity and quality. SWI happens when saline water infiltrates coastal aquifers, contaminating freshwater supplies. This review article aims to define SWI, explore its causes and influencing factors, and discuss various monitoring techniques. Additionally, it examines different modeling methods and management tools, including remote sensing, field surveys, modeling approaches, and optimization techniques. To mitigate the adverse effects of SWI, several control measures are outlined, along with their pros and cons. The final section reviews previous SWI studies and case studies from the Nile Delta, Sinai Peninsula, and North-West coast in Egypt. These studies offer suggestions, adaptations, and mitigation measures for future research.

Over the past decades, quality assurance has received significant prominence in higher education management across the world. While the concept is pertinent to all areas of higher education management, nowhere is it considered more crucial than in curriculum development, given the importance of curriculum in supporting students to achieve the needed learning outcomes. In this study, we explored how quality is ensured in curriculum development in Ghana, using a STEM university, University of Mines and Technology (UMaT), as a case study. We specifically examined the procedure for curriculum development in the university, how quality assurance is ensured during the process, and the challenges associated with the process. We explore the case using qualitative techniques, particularly in-depth interviews. Fourteen (14) participants were purposively sampled from four (4) functional levels responsible for curriculum development in the university. The study found that the quality of curriculum in UMaT is largely determined by both national and institutional quality assurance frameworks. The major challenges that hamper quality assurance are the need to design curriculum at a shorter notice to fulfil accreditation requirement, lack of experts to support curriculum development, and less consultation with other relevant stakeholders as required by the regulator, Ghana Tertiary Education Commission (GTEC).

PLCs, or programmable logic controllers, are essential parts of contemporary industrial automation systems and are responsible for managing and keeping an eye on a variety of operations. PLC reliability is critical to maintaining industrial systems' continuous and secure operation. A wide range of reliability strategies were used to improve the reliability of Programmable Logic Controllers, and this article methodically looks at them all. The evaluation classified PLC reliability techniques into Root Cause Analysis (RCA), Reliability Centered Maintenance (RCM), Hazard analysis (HA), Reliability block diagram (RBD), Fault tree analysis (FTA), Physics of failure (PoF) and FMEA/FMECA, after thoroughly reviewing the body of literature. The proportion of reviewed papers using either RCA, RCM, FMEA/FMECA, FTA, RBD, RCM, PoF, or Hazard analysis to increase the reliability of PLCs showed that RCA, which makes up 20% of the publications reviewed, has been used the most to increase the reliability of the PLC, followed by HA, RCM, RBD, FTA, and PoF, which account for 17%, 16%, 16%,13%, 10%, and 8% of the articles reviewed, respectively. The paper discusses new developments and trends in PLC reliability, such as the application of machine learning (ML) and artificial intelligence (AI) to fault detection and predictive maintenance.

This study aimed to evaluate the Social Studies Curriculum for Senior High Schools in Ghana to determine whether the subject has attained its goal(s) or not, using Stake’s Countenance Evaluation Model. The study took place in the Asante Akim North District. The population for study were all Social Studies teachers and students in the district. The multi-stage sampling technique was adopted for the study and the sample size was 120, made up of 100 students and 20 teachers. The concurrent mixed method approach was adopted. The main instruments used for collecting data were questionnaires, interviews (focus group and unstructured interview), observation and documentary analysis. Quantitative data were tabulated, organised, analysed and interpreted to draw sound conclusions and generalisations. The data were presented in the form of tables and percentages. Words were used to interpret the tables and percentages for easy understanding. The qualitative data responses were described and explained in the form of themes. Sometimes responses were quoted verbatim to authenticate claims made. The study looked at the congruence between what was intended to occur and what was observed before and during the implementation of the curriculum in the Asante Akim North District. On the transactions, it was revealed that teachers in the district communicate the problem the topic seeks to address and the specific objectives to the learners during instruction. Also, teachers varied their teaching methods, techniques and strategies. However, teachers failed to take students out on field trips. Also, they failed to use video documentaries to deliver their lessons inhibiting students’ creativity as they are denied the opportunity to explore and get first-hand information to build up knowledge and develop the needed attitudes and values. From the findings, it is therefore recommended that the National Council for Curriculum and Assessment should increase the time allotted to the teaching of Social Studies at the SHS level from 3-periods of 40 minutes a week to 5-periods of 40 minutes a week to give teachers and learners ample time to discuss, debate, digest and solve problems during instructional hours to enable the goal of the subject attained.

The purpose of this study was to examine the challenges affecting the teaching and learning of Social Studies in the Colleges of Education in the Ashanti Region. Qualitatively, the study adopted a case study research design. The population of the study comprised fifteen (15) Social Studies teachers in the Ashanti region of Ghana. A purposive sampling technique was used to select the colleges and Social Studies teachers. The main instrument for data collection was an unstructured open-ended interview guide. Four criteria proposed by Lincoln and Guba in 1985 used to measure the trustworthiness of data collected are credibility, transferability, dependability and confirmability. Data obtained from the study were subjected to thematic analysis using themes developed from the data collected based on the research question. The findings of this study indicate that adequate textbooks, availability of teaching and learning materials such as projectors, the ability of tutors to engage in research, and the ability to vary teaching techniques are some factors that affect the teaching and learning of Social Studies in Colleges of Education. Students can remember a greater percentage of what was taught when techniques used by teachers are in their interest. It is recommended that T-TEL and Universities to which Colleges of Education are affiliated should continue to provide seminars and sessions to tutors in areas of material, resource development and research. This will continue to ensure that tutors are competent in their field of specialization. It is also recommended that the government should conduct a nationwide programme evaluation exercise on Social Studies to identify the loopholes needed to ensure the effectiveness of the subject.

Digital forensics in cloud computing environments presents significant challenges due to the distributed nature of data storage, diverse security practices employed by service providers, and jurisdictional complexities. This study aims to develop a comprehensive framework and improved methodologies tailored for conducting digital forensic investigations in cloud settings. A pragmatic research philosophy integrating positivist and interpretivist paradigms guides an exploratory sequential mixed methods design. Qualitative methods, including case studies, expert interviews, and document analysis were used to explore key variables and themes. Findings inform hypotheses and survey instrument development for the subsequent quantitative phase involving structured surveys with digital forensics professionals, cloud providers, and law enforcement agencies, across the globe. The multi-method approach employs purposive and stratified random sampling techniques, targeting a sample of 100-150 participants, across the globe, for qualitative components and 300-500 for quantitative surveys. Qualitative data went through thematic and content analysis, while quantitative data were analysed using descriptive and inferential statistical methods facilitated by software such as SPSS and R. An integrated mixed methods analysis synthesizes and triangulates findings, enhancing validity, reliability, and comprehensiveness. Strict ethical protocols safeguard participant confidentiality and data privacy throughout the research process. This robust methodology contributed to the development of improved frameworks, guidelines, and best practices for digital forensics investigations in cloud computing, addressing legal and jurisdictional complexities in this rapidly evolving domain.

Journal of Artificial Intelligence and Big Data 2023, 3(1), 4-16. DOI: 10.31586/jaibd.2024.917

Abstract Failure prediction can be achieved through prognostics, which provides timely warnings before failure. Failure prediction is crucial in an effective prognostic system, allowing preventive maintenance actions to avoid downtime. The prognostics problem involves estimating the remaining useful life (RUL) of a system or component at any given time. The RUL is defined as the time from the current time [...] Read more.

Failure prediction can be achieved through prognostics, which provides timely warnings before failure. Failure prediction is crucial in an effective prognostic system, allowing preventive maintenance actions to avoid downtime. The prognostics problem involves estimating the remaining useful life (RUL) of a system or component at any given time. The RUL is defined as the time from the current time to the time of failure. The goal is to make accurate predictions close to the failure time to provide early warnings. J S Grewal and J. Grewal provide a comprehensive definition of RUL in their paper "The Kalman Filter approach to RUL estimation." A process is a quadruple (XU f P), where X is the state space, U is the control space, P is the set of possible paths, and f represents the transition between states. The process involves applying control values to change the system's state over time.

An Attitude of Staff and Students towards Littering in Second-Cycle Schools in Sefwi Wiawso Municipality in the Western North of Ghana

Simon Nipah, Alexander Kingsford Otoo, Anthony Bordoh, Isaac Eshun

Universal Journal of Social Sciences and Humanities 2024, 4(1), 20-34. DOI: 10.31586/ujssh.2024.709

Abstract The growing unconcern and poor attitude of some Ghanaians towards environmental protection and sanitation practices has become very endemic in Ghanaian Societies. Littering especially is considered a major environmental problem within the setting of this study. This study employed the mixed-method approach in integrating qualitative and quantitative research data. The study adopted a convergent parallel research design. The population for this study consisted of all teaching staff and students of Sefwi Wiawso Senior High Technical School and St. Joseph Catholic Senior High School in Sefwi Wiawso municipality in the Western North Region of Ghana. Purposive, simple random, and convenient sampling techniques were used to select the schools, teachers and students for the study. A sample size of one hundred and ninety-eight (198) consisting of one hundred eighty-eight (188) students and ten (10) teachers were selected for the study. The two main instruments used for data collection were questionnaires and interview guides. The quantitative data obtained from the questionnaire were coded with numerical values and keyed into the data view of the SPSS version 23. The qualitative data was analysed through content analysis and was further transcribed into themes for analysis with a side-by-side comparison with the quantitative data. The qualitative data gathered and presented, were organised and analysed manually using emerging themes. The study revealed that littering is currently caused by irresponsible behaviour among some staff and students coupled with other factors such as lazy attitudes among people, inadequate waste bins on campus, and more seriously, less sensitization of people on littering in the various senior high schools. The study also indicated that provisions of adequate waste bins at vantage points in the various campuses, awarding prizes to individual students and groups with good waste management practices on campus, implementing rules and regulations on littering, as well as educating, and sensitizing students and staff on littering on campuses formed the possibilities on how schools can shape up staff and student’s attitudes towards healthy environment by avoid littering. It is recommended that Students with good waste management practices should be rewarded to encourage others in Senior High Schools. It is also recommended that sustainable waste management practices (collection, transportation, and treatment) should be employed in all the Senior High Schools [...] Read more.

The purpose of this study was to examine indicators of forgiving behaviour and intervention among adolescent students in Junior High School in Bimbilla in the Nanumba North Municipality of Ghana. This study adopted the Pragmatist philosophy. The mixed methods experimental design was used for the study. The study population comprised all adolescents in Junior High Schools in the Nanumba North Municipality of the Northern Region, Ghana. Purposive, random sampling techniques Krejcie and Morgan's table of determination of sample size were used for the schools and respondents for the study. Two major instruments were used for this study: a questionnaire and an interview guide. The interview schedule was used to gather the qualitative data whereas the quantitative data was gathered using the questionnaire. The study indicated that both the REACH model and Process model are efficacious in reducing the level of depression among adolescent students when their levels of forgiveness are increased through forgiveness counselling regardless of gender and age. The findings also revealed that both REACH and Process models were good interventions for the adolescents in showing greater emotional regulation (increased forgiveness, reduced anger and reduced depression, enhanced sense of well-being, positive feelings and positive thoughts towards the offender). It is recommended that counsellors organise training programmes with parents in conjunction with Non-governmental organisations on using the Process and REACH models. This will bring awareness of the interventions and encourage parents to seek assistance anytime their adolescents need assistance. It is once again recommended that teachers and school administrators consider forgiveness interventions (the Process model and REACH model) as a very effective strategy for treating unforgiveness to improve students' psychological well-being.

Qualitatively, the study focused constructivist research paradigm. A case study research design was adopted for the study. The study population comprised all six (6) Social Studies teachers, the headmaster and the School Improvement Support Officer (SISO). Purposive and convenient sampling techniques were used to select the participants for the study. The main instrument for data collection was a semi-structured interview guide and observation protocol. The data were analysed using the interpretative technique based on the themes arrived at during the data collection from the semi-structured interview. The study revealed that multimedia usage is a quality enhancer in educational settings for teaching Social Studies concepts. It also indicated that teachers perceived their incompetence when using technology as they feel less in control of their classes and are unlikely to explore new possibilities that utilise technology when planning their lessons. They learn the theoretical aspect and practice and perceive the teacher’s role in the classroom changes from an instructor to a facilitator, which changes the teaching method to student-centred (constructive methodology) which aids content absorption by the learner through learning by doing. The study also indicated that teachers perceived their incompetence when using technology as they felt less in control of their classes and were unlikely to explore new possibilities that utilised technology when planning their lessons. It is recommended that the Ministry of Education and National Teaching Council collaborate with Ghana Education Service to set up Social Studies training centres in all the district capitals equipped with competent staff to periodically organise in-service training for teachers to build their capacity on how to pedagogically incorporate multimedia resources in their instructions to improve students learning outcomes.

Challenges are part and parcel of human activities. Quantitatively, a relational survey model research was adopted for the study. The population for this study comprised all Junior High School (JHS) Religious and Moral Education (RME) students in Bokro M/A JHS and the Eziom Methodist JHS in the Nzema-East Municipality of the Western Region. Purposive and random sampling techniques were used to select the schools and respondents for the study. The main instruments for data collection were a test and a questionnaire. The data from both the control and experimental groups on the challenges learners face in using the flipped classroom model in RME were analysed using means and standard deviations. The study indicates the challenges learners face by employing the flipped classroom model to learn include lack of data to access the internet, frequent light outs, lack of technological devices to access contents, frequent power outages, and difficulty in comprehending some of the materials given to them. Given that learners face frequent power outages during periods that they watch videos assigned to them by their teachers, it is recommended that the government and the Electricity Company of Ghana ensure that there is a constant flow of power to allow learners trying to use the flipped classroom to learn are without any hindrance. It is also recommended that the Ghana education service should organise continuing professional development for RME teachers on effective uses of technology in teaching and learning subject concepts. The government should also supply the basic schools with all the needed technological devices to promote effective teaching, learning and assessment.

The purpose of this study was to examine the influence of new religious movements’ televangelism on women in Dunkwa-on-Offin in the central region of Ghana. The study adopted the sequential explanatory mixed-methods approach. The study population was important because they make up a bigger share of individuals who attend mainline churches and are constantly exposed to televangelism in their daily lives. A multi-stage sampling technique (purposive and simple random sampling techniques) was used to select two hundred (200) women for the study. Krejcie and Morgan's table determined the two women population of 400 (for both churches). The main instruments for data collection were questionnaires and interview guides. Quantitative data was analysed with the use of the IBM SPSS statistics software version 23, to compute frequency distributions, percentages, tables and cross-tabulation. Descriptive statistics and inferential analysis were employed in the analysis of the data. Qualitative data was analyzed thematically by identifying relevant information, coding, classification and summaries. The study revealed that televangelism has influenced women to follow televangelists rather than the teachings of their churches. Also, the activity has influenced the youth and women to follow false teachings, prosperity and vain promises of travelling. The findings of the study revealed that televangelists’ messages are geared towards obtaining money and raising unrealistic hopes. It is recommended that the government should also establish and enforce policies and regulations that encourage genuine televangelism programming and deter televangelists who are driven by fraud and self-gain by registering all the churches and holding them accountable for their actions.

The purpose of the study was to examine the effect of REACH and Process Models on forgiveness, anger and depression among 11- to 19-year-old adolescents in junior high schools in Bimbilla in the Northern Region of Ghana. The study employed a mixed-method design. The population for the study comprised all junior high school students totalling 3632. Of this number, 1,888 (55%) of the students were males, while 1744(45%) were females. The accessible population was 1,636 from eight (8) JHSs with 952(55%) of them being boys and the remaining 684(45%) being girls. The participants were selected based on their low levels of forgiveness and high levels of anger and depression determined by the Depression Mode Scale and Anger Self-Report. Purposive and simple random sampling techniques were used to select 60 participants for the study, with each group having 20 participants. The main instruments used for the study are questionnaires (Enright Forgiveness Inventory (EFI). Anger self-report questionnaire (ASR), and Depressed Mood Scale (DMS) and semi-structured interview guide. One-way Analysis of Covariance (ANCOVA) was used to test the hypotheses. The study indicates that both the REACH model and PROCESS model have the efficacy in enhancing forgiveness among adolescents. The study also revealed that the REACH model and Process model have efficacy in reducing levels of depression among adolescent students. It is recommended that Counselling Centres should be set up by District Education Offices and the District Assemblies in the community so that students can visit the centre anytime they feel hurt. Regular seminars, lectures and symposia should be organized regularly by Counsellors and Psychologists using the efficacy of forgiveness therapies (Process and REACH Therapies) for students to be sensitized on the need to patronise forgiveness interventions. It is also recommended that the Government should provide adequate funds and support to encourage the conduct of research in forgiveness counselling since it is a new concept in Africa and Ghana in particular.

The world of the stock market is an intricately complex financial ecosystem that demands years of dedicated study to comprehend fully. It relies on risk mitigation practices and fundamental theoretical techniques to engage in speculation regarding stock and cryptocurrency fluctuations. However, this realm is progressively becoming more inclusive, with accessibility expanding beyond traditional educational barriers. Technological advancements, coupled with the ease of entry into this domain and the information-disseminating power of social networks, contribute to a rising number of individuals participating in this financial movement. What makes this evolution disruptive is that the same tools facilitating accessibility also exert influence on the way market trends unfold. This paper delves into the escalating impact of social media within the financial sphere, emphasizing the heightened accessibility to information and market involvement facilitated by platforms like Twitter and Reddit. It sheds light on how social media plays a pivotal role in market manipulation, as evidenced by phenomena such as the r/wallstreetbets subreddit, where meme-based strategies were employed to inflate the prices of stocks like GameStop. The study explores the utilization of social media by influential figures, exemplified by Elon Musk, who leverage their platforms to sway market movements. Additionally, this paper addresses instances of misinformation, such as the confusion surrounding Virgin Galactic's shares following a SpaceX failure and the introduction of "AGUA" in the Mexican stock market, leading to widespread misunderstandings. The paper extends its examination to the effects of social media on cryptocurrencies, highlighting how comments from public figures can significantly impact the prices of Bitcoin and Dogecoin. Overall, it underscores the imperative need for adaptation to these changes in the digital financial paradigm.

English language has become a global language due to first, the results of British colonial expansion and, global commercial interests. It has become a lingua franca in many countries, including Ghana. Qualitatively, the study adopted case study research design. The purpose of the study was to find out the perception and the attitude of Ghanaian English teachers towards the Native Speakers’ accents. The population of study consists of all ten (10) tutors in the Department of Languages, Offinso College of Education. Purposive and convenient sampling techniques were used to select the college and the tutors for the study. The main tool used for the collection of data was the semi-structured interview. Most of the participants revealed positive attitudes towards their own English accents which were different from that of the native speaker. Ghanaians are often faced with the challenge of which accent to use when communicating with each other and with outsiders. Most of the tutors from Offinso College of Education who participated in this study expressed positive responses to their non-native speaker’s accents. Not only did the idea of having a native speaker’s accent hold no attraction for them but they also found it strange because it would not represent their L1 identity. The majority of participants in this study preferred to use their non-native accents to attempt to adopt those of the native speaker. To them, there is only one distinction between English accents -you are either a native or non-native.

Family planning and the use of contraceptives have been introduced in Ghana to control the fertility rate and ensure the prevention of unplanned pregnancies. The study examined the perceptions of married men and women on the use of contraceptives, their access to information and the effects of mass media on the use of contraceptives in the Obuasi-East District. The research adopted a qualitative approach using the phenomenological case study design. Purposive and convenience sampling techniques were used to sample 15 married men and women for the study. The data was collected using interviews and presented through thematic analysis. The study revealed that participants had in-depth knowledge of contraceptives and male and female participants held different perceptions. Married men have knowledge of the types of contraceptives peculiar to both sexes. The women were familiar with condoms used by men and various types of contraceptives used by women. The most common contraceptive known and used by married men is a condom because of its effectiveness, ease of use and accessibility. The married women preferred injectables. The frequency of information from the mass media has reduced significantly compared to previous years. The study concluded that mass media has an effect on the use of contraceptives among married men and women and recommends that mass media frequently educate the general public on the use of contraceptives. Besides, information on contraceptives and their use should be diversified by media houses in the form of drama, poems, books and music to attract married couples.

The review article presents how emerging technologies improves the business enterprise applications for process management. The paper considers certain technologies of enterprise applications and justifies the updated methodological and analytical tools for assessing, selecting, and regulating business processes in a single enterprise resource planning (ERP) system. Information technology must be used to identify products, track their movement into and out of the warehouse using code scanning technology, and streamline the product management procedure. To increase the dependability of management techniques, guarantee that the business operates flawlessly, and maintain a regular management mode, the process management form should be implemented in the enterprise management process. The implementation of digital information technology is essential for achieving effective corporate management. In addition to providing ideal operational circumstances for businesses, it is essential to analyse information technology and manage businesses economically. The foundation for implementing the enterprise applications method strategy is the creation of a process management system and an in-depth, methodical review of the enterprise as a collection of processes. Process-oriented enterprise applications should be the foundation of contemporary novel technologies for modelling business processes. It shares a tight relationship with workflow management systems (WFM), enterprise resource planning (ERP), and total quality management (TQM).

The objective of this research was to investigate work-family conflict among management staff of hotels in the Accra Metropolis of Ghana. The study employs the pragmatism approach and Convergent parallel mixed methods research technique. The population of the study is all-star-rated management staff of star-rated hotels in the Accra metropolis. Stratified, random and convenient sampling techniques were used to select 182 out of 356 respondents. One hundred (100) were sampled using a formula and a table determination of sample size based on the confidence level needed from a given population as provided by Krejcie and Morgan in 1970 for the study. Ten managers were conveniently interviewed on the issues of work-family conflict. The main instruments for data collection were a questionnaire and a semi-structured interview guide. This study adopted factor analysis and a structural equation model to examine factors that influence work-family conflict. This statistical technique was used in the research to investigate the factorability of the variables of work-related and family-related factors separately and a structural equation model was used to combine both factors to better understand the relationship. Linear regression was used to determine the relationship between work-family conflict. Pearson product-moment Correlation and structural equation model were used to determine the consequences of work-family conflict. It can be concluded that both work-related such as work overload, job type and involvement as well as family-related factors such as life cycle stage, and childcare arrangement predict work-family conflict among managers of hotels in the Accra metropolis. It is also deducted WFC affect managers’ performance on the job, exhaust them emotionally and also influences their intentions to leave the job for another. Managers usually feel fatigued to prepare for work and physically drained after work. They also feel depressed and emotionally drained sometimes. It is recommended that top management of hotels should allocate a budget to build an organisational culture that encourages work-family balance. Frontline managers should be trained to be aware of the benefit of providing support in the work environment that will help staff balance work and family. It is also recommended that hotel jobs be redesigned by the human resource unit to reduce workload and make it more interesting for managers so they may not feel overworked. Overworking of managers will enhance their intentions to quit the job and this will be costly for hotels.

Abstract The purpose of this study was to examine the empirical analysis of lexico-grammatical features used in the rhetorical structure of the Statement of the Research Problems of Master of Philosophy theses in the Faculties of Arts and Education at the University of Cape Coast, Ghana. Qualitatively, content analysis was adopted for this study. Theses from the Faculty of Arts and the Faculty of Education at the University of Cape Coast were selected for this study. These theses were selected from 2012 to 2022 academic years to ensure currency in terms of the stipulated lexico-grammatical features used in the statement of the research problem. Purposive and simple random sampling techniques were used to select the university, two faculties (Faculty of Arts and Faculty of Education) and postgraduate theses for the study. The two faculties were purposively sampled. Eighty (80) theses were simple randomly sampled (Forty (40) theses each from the Faculty of Arts and the Faculty of Education). The main instrument used for data collection was content analysis. The data was analysed by the use of the interpretative technique based on the themes arrived at during the data collection of the statement of research problem from the post-graduate theses. The study indicated that integral citation was dominant in SRPs from the Faculty of Arts theses whereas non-integral citations were rather dominant in SRPs from the Faculty of Education theses. The use of adverbials to boost these claims was also found in only the SRPs from the Faculty of Arts theses. The use of hedging devices in SRPs from both Faculties to indicate a gap, and the use of simple noun phrases such as “the problem” and “the need [...] Read more.

The use of adverbials to boost these claims was also found in only the SRPs from the Faculty of Arts theses. The use of hedging devices in SRPs from both Faculties to indicate a gap, and the use of simple noun phrases such as “the problem” and “the need” were mostly used to categorically state the research problem. It is recommended that a comparative study of theses in the two faculties in another university in Ghana be undertaken to identify how similar or otherwise the rhetorical structure and the lexico-grammatical features of the SRPs written by postgraduate students in the two faculties will be.

Open Journal of Food and Nutrition 2023, 1(1), 64-73. DOI: 10.31586/ojfn.2023.765

Abstract Networking has become more common in recent years because it provides structural support and consistent avenues for contact among experts. The purpose of the study was to examine tutors’ and students’ perceptions and sustenance of networking in Food and Nutrition education in the Colleges of Education of Ghana. Quantitatively the study employed a cross-sectional survey research design. The population of the study comprised tutors and students in the Colleges of Education in Ghana offering Food and Nutrition. Purposive, stratified and simple random sampling techniques were used to select colleges of education, 16 tutors and 256 students for the study. The main instrument used for data collection was a questionnaire. The data collected were processed and analysed with the aid of Statistical Package for Social Sciences (SPSS) version 23.0. All statistical analyses were tested at a 5% level of significance. Levene's Test for Equality of Variances [...] Read more.

Networking has become more common in recent years because it provides structural support and consistent avenues for contact among experts. The purpose of the study was to examine tutors’ and students’ perceptions and sustenance of networking in Food and Nutrition education in the Colleges of Education of Ghana. Quantitatively the study employed a cross-sectional survey research design. The population of the study comprised tutors and students in the Colleges of Education in Ghana offering Food and Nutrition. Purposive, stratified and simple random sampling techniques were used to select colleges of education, 16 tutors and 256 students for the study. The main instrument used for data collection was a questionnaire. The data collected were processed and analysed with the aid of Statistical Package for Social Sciences (SPSS) version 23.0. All statistical analyses were tested at a 5% level of significance. Levene's Test for Equality of Variances was computed to determine the significant difference in the perception of networking in Food and Nutrition education between tutors and students. It can be concluded that both tutors and students are in favour of networking in Food and Nutrition education. The tutors and students believed networking education can foster collaboration, help implement new ideas to improve the quality of teaching, create an environment conducive to teaching and learning; and help students in sharing vital information. Since there is a positive perception on the use of networking, it is recommended that the tutors should foster collaboration, and create a conducive environment to enhance the positive perception and smooth implementation of networking in Food and Nutrition education at Colleges of Education in Ghana. The study indicated that in order to sustain networking education, teachers need to be more cognizant of their interactions and the influence they have on students. It is therefore recommended that teachers maintain contact with students, and ensure a spirit of unity in diversity among the students.
