Cyberbullying Experiences and Coping Strategies in Ibadan Metropolis, Ibadan, Nigeria

Introduction/Aim: Cyberbullying of influential personalities or celebrities is a media menace. Psychological, depressional, and emotional suicidal ideation effects are some of the impacts on celebrities. A few studies have investigated celebrities' coping mechanisms against this, with the majority from developed countries. There is a dearth of information on this among celebrities in Nigeria. This study investigated the experience, effects, and coping mechanisms of cyberbullying among celebrities in the Ibadan metropolis, Oyo State, Nigeria. Material and method: A descriptive crosssectional purposive sampling method was adopted. An in-depth interview guide was used for data collection among 14 consented celebrities. Data were manually analysed thematically. Results: Most participants were 25-35 years old and were comedians. All have experienced cyberbullies, such as popularity attacks and defamation of character. The effects of cyberbullying on the victims include low self-esteem, mental stress, depression, substance abuse, and financial crisis. Jealousy, hatred, envy, and quest for popularity among the perpetrators fuelled this menace. However, some celebrities have overcome these effects through technical, preventive, corrective, social support, and spiritual approaches. Conclusion: Cyberbullying is prevalent among celebrities and many experienced psychological effects. Awareness, interventions aimed at its prevention, and adequate coping strategies are needed to solve this menace

Influence of Shredded Waste Water Sachet on Engineering Properties of Asphalt

The search for any improvement has always brings about some sort of modification especially if a new discoveryhas not been made. This research work focused on the potential utilization of waste water sachets in themodification of the engineering properties of asphalt cement (Bitumen) used in the production of Asphalticconcrete.In achieving this, the samples of waste water sachets were collected from four sachet water producing companiesin Ilorin. They were sun dried and later shredded. The bitumen was replaced by shredded waste water sachets byweight at 1 to 10%. Some conventional Laboratory tests were carried out on the unmodified and modifiedbitumen specimens.The property of bitumen was strongly affected by the addition of shredded water sachet. The specifications ofAmerican Society for Testing and Materials {ASTM} and Government of Federal Republic of Nigeria GeneralSpecifications for Roads and Bridges were employed as guides. A modification of 1 – 3 % could be allowed asalmost all requirements are met except the Softening Point of 3 % modification that seems to be on the high side.The modification enhances the resistance to permanent deformation, fatigue cracking and cohesion. Furtherstudy of the research is encouraged and could involve asphalt concrete production from the modified asphaltcement to investigate the effects.Keywords: Waste water sachets, Bitumen, Modification, Engineering properties

Modelling and optimization of the drying process and the quality parameters of dried osmo-pretreated onions (Allium cepa)

Modelling and optimization represent an important aspect of drying in food processing, providing a fast and convenient means for quality prediction. The research focuses on modelling and optimization of process parameters such as drying rate, water loss, solid gain, vitamin C, manganese, and iron of dried osmo-pretreated onion slices. Least square regression analysis in the Math-lab computer software was used to model and optimise the process parameters., Six (6) mathematical models were developed for each output from the regression analysis that was carried out. The criteria for adjudging these models were the values of their adjusted coefficient of multiple determinations, prediction error sum of squares (also called deleted residual), R2 for prediction, coefficient of variation CV, and the Dubin-Watson test for autocorrelation. The models were checked for adequacy using these criteria, and those found to be adequate were selected from among the other possible combinations. Hence, the best-optimized obtained results from the models are 27.50 g/h, 1.61 g/g, 0.15 g/g, 77.52 mg/100 g, 2.79 mg/1000 g, and 2.19 mg/1000 g for drying rate, water loss, solid gain, vitamin C, manganese, and iron, respectively

Teachers’ and students’ level of utilization of ICT tools for teaching and learning mathematics in Ilorin, Nigeria

Information and Communication Technology (ICT) is an instrument par excellence that a nation can rely upon to bring about self-reliance in an educational system. Therefore, there is the need to integrate ICT into teaching and learning; hence, the study investigated the assessment of Teachers’ and Students’ level of utilization of ICT tools for teaching and learning mathematics in Ilorin, Nigeria. The study was a descriptive research of the survey type. The population for the study was all senior secondary schools in Ilorin, Kwara State. A total of 170 students and 50 mathematics teachers were randomly selected from senior secondary schools in Ilorin. The instrument used for the study was a researchers-designed questionnaire, which comprised of 24 ICT tools. The instrument was validated and the reliability index of 0.78 was obtained. The data gathered was analyzed statistically using simple percentage and Chi-Square statistics analyses. The findings revealed amongst others that; mathematics teachers and students utilized ICT tools for teaching and learning mathematics respectively. Also, mathematics teachers and students were not skilled in utilizing ICT tools. The findings from the study show that the gender of both teachers and students does not have any influence on the teaching and learning of mathematics with the use of ICT tools. Based on the findings, It was, therefore, recommended among others that seminars and workshops should be organized for both female and male mathematics teachers on the benefits and how to incorporate ICT tools into their teaching activities and students should be encouraged to familiarize themselves with ICT tools so as to increase their level of competencies in the use of ICT tools

Normal Aerobic Vaginal Bacterial Flora of The African Giant Rats (AGR) Captured from Their Natural Habitat in Abeokuta, Ogun State, Nigeria

The genital tract of female animals, especially the caudal region, is known to habour non specific bacteria that are sometimes called the normal bacterial flora. In this study, we examined 12 apparently healthy female African giant rats (Cricetomys gambianus, Waterhouse) (AGR) to determine their vaginal bacterial flora. Swab collected from the vagina of each rat after previous chloroform anaesthesia was seeded onto blood and MacConkey agar plates and incubated aerobically at 370C for up to 48hours. Isolates were then characterized using various character parameters. The results indicated that 7 bacterial genera inhabit the vagina of the 12 African giant rats that were studied. The distribution of the bacteria species in the AGR were highlighted in the text. It is inferred from the results that under stress condition, these bacteria could cause disease in the African giant rats

PERCEIVED INFLUENCE OF CUSTOMERS' IMAGE OF AN ORGANISATION ON PATRONAGE:AFOCUSONECOBANK

The rate at which most organisations are losing customers has increased in recent years. The confidence and credibility that some of their customers have in them have eroded. The reason for this trend is not farfetched; it is the lack of effective Public Relations to create or change the image that the customers already have of them. In this research, "Perceived influence of customers' image of an organisation on patronage: A focus on Eco bank". There was an attempt to find out if the customers of Ecobank have had experiences worth keeping as an image of the bank. The image they have formed of the bank through their communication processes would affect their decision of continuous patronage and loyalty to the bank. The major objective of this study is to determine the extent to which these images that are formed help to keep the customers. The study design used was Survey. Since the whole of the customers of the bank in Nigeria cannot be used, the researchers focus on Lagos State. Lagos State is a large settlement and because of this. the study population was stratified to two commercial and industrial localities, ikeja and Victoria island. These places were selected and made representatives of the organization under study. Eight branches of the bank 11·ere used and a sample size was 400 respondents. 50 copies of the questionnaire were administered in each of the eight branches. The researchers found out that the percentage qf respondents n•ho have a positive image of the bank is 52%. it was also found out that many of the respondents consider their experience with the bank good (35%), while those who consider their experiences with the bank as fair are 2 5%. However, 17% of the respondents think the experiences have been bad, while 23% of the respondents are indifferent about their experience. The researchers therefore recommends among others that thorough training should be carried out for the staff of Eco bank because based on the findings of this research; many customers do not etijoy the services they get from certain members of staff Therefore, they should be trained in other to avoid having multiple images of the bank which can be as a result pf staff acting differently in their various branches

GEOELECTRICAL INVESTIGATIONS FOR GROUNDWATER EXPLORATION IN CRYSTALLINE BASEMENT TERRAIN, SW NIGERIA: IMPLICATIONS FOR GROUNDWATER RESOURCES SUSTAINABILITY

This research involves the subsurface geological characterization for groundwater potential assessment within the campus of the Polytechnic of Ibadan, southwestern Nigeria. The study is directed towards groundwater resources exploration, development and management in the campus. Five 2D resistivity imaging traverses were conducted using Wenner array in addition to five VES surveys using Schlumberger array that provide layering information and geoelectrical parameters. Three geologic layers delineated from the 2D resistivity inversion models include predominantly clayey sand/ sandy clay top soil (overburden), partly weathered or fractured basement and fresh basement. Their inverse model resistivity values ranges 6.68 – 98.6 m , 68.0 – 929 2252 m and m with bottom depths ranges 3.8 – 6.4 m and 6.4 – 10 m respectively. 1D model inversion from VES results also delineate three lithologies classifying both topsoil and some part of the partly weathered basement as overburden with resistivity and thickness range 483 – 1746.9 m , 1.1 – 1.8 m; partly weathered or fractured basement 60.3 – 93.5 m , 8.4 -12.9 m and fresh basement 984.6 – 2078.9 m . The saturated portion of the partly weathered or fractured basement at depth will favour groundwater exploration and development in this area, while the relatively shallow overburden thickness would serve as the protective layer and recharge for the fractures

Investigating groundwater pollution at an open dumpsite using 2D geoelectrical resistivity imaging and vertical electrical sounding

Geoelectrical resistivity survey has been conducted within the Kurata dump site in Ota, south-western Nigeria. This present study focuses on the use of 2D resistivity imaging and Vertical Electrical Sounding to delineate conductive leachate point and degree of movement within the subsurface for conceivable groundwater pollution. The 2D resistivity survey was carried out using the ABEM Terrameter (SAS 1000/4000) System with multiple-gradient array electrode configuration. The Vertical Electrical Sounding was conducted using the schlumberger electrode configuration. One 2-D imaging profile of length 100m and one Vertical Electrical Sounding of length 200m were acquired on the established traverse. The resistivity data was inverted utilizing RES2DINV and WinResist to obtain the inverse model resistivity distribution. The 2D inverse resistivity models of the subsurface showed that the study site has a multi-layered aquifer system, four geoelectrical layers were inferred from the resistivity imaging and they are lateritic clay, clayey sand, sandy clay and coarse sand units. There is one aquifer system about 13 m which is highly polluted. The unpolluted aquifer system is localized around 19 m with inverted resistivity range 498Ωm – 685Ωm in the traverse. Also there might be conceivable sullying of deep groundwater system in the long term if appropriate moderation procedures are not thought about at the area
