SIGNATURE OF ATMOSPHERIC DYNAMICS ON SURFACE OZONE VARIABILITY IN NIGERIA

An examination of analysis revealed that surface ozone concentration over Nigeria varied with direction of the local trade winds, namely the Harmatan, and the Gulf of Guinea maritime trade winds. In DJF and MAM the period of the dry dusty Harmatan seasons, surface ozone concentration in the southern Nigeria exceeded that of the north by 21DU and 24DU respectively. Whereas in the JJA and SON, the rainfall season, reversal was the case, the surface ozone concentration in the northern Nigeria exceeded that of the south by 20DU and 15DU respectively. Maximum temporal variation gradient of 20DU was also observed in MAM season while the minimum of 11DU occurred in JJA which is the peak of the raining season

Estimating solar radiation in Ikeja and Port Harcourt via correlation with relative humidity and temperature

This paper is part of the Proceedings of the 6th International Conference on Energy and Sustainability (ESUS 2015). http://www.witconferences.comRelative humidity and temperature data are more readily available to obtain from observatories than sunshine hour data. In this work, 10 years (1986–1987, 1990–1997) monthly average measurement of relative solar radiation, daily temperature range, relative humidity and the ratio of minimum to maximum temperature were used to establish the coefficient of eight models for estimating solar radiation in Ikeja and Port Harcourt. Coefficient of correlation (R), Mean Bias Error (MBE), Root Mean Square Error (RMSE), Mean Percentage Error (MPE), t-statistic and the rank score were used as performance indicators. In Port Harcourt, the equation producing the best result with MBE, RMSE, MPE and t-statistic value of −0.1078, 0.9850, −0.4373% and 0.3653, respectively, is given by: Rs/Ro = 3.266 − 0.306(RH)0,5. In Ikeja, the equation producing the best estimation with MBE, RMSE, MPE and t-statistic value of 0.1590, 1.0110, 2.0559% and 0.5281, respectively, is given by: Rs/Ro = 2.042 − 2.136(θ)

A Systematic Review on Social Housing in Nigeria: Challenges, Prospects and the Road Ahead

Social housing in Nigeria plays a crucial role in enhancing well-being and development, necessitating heightened attention and action from stakeholders. This systematic review investigates the challenges, prospects, and future directions of social housing provision and its impact on the country. Employing a mixed-methods approach encompassing descriptive statistics, thematic analysis, and meta-analysis, data from 42 relevant articles published between 2010 and 2022 are analysed. The study addresses four key research questions: Factors influencing social housing delivery in Nigeria, Factors influencing social housing design in Nigeria, Factors affecting social housing affordability in Nigeria, and Factors influencing the impact of social housing in Nigeria. Findings unveil the multifaceted nature of social housing in Nigeria, shaped by diverse factors impacting its provision and effects. Moreover, social housing yields mixed outcomes across social, economic, and environmental dimensions of well-being and development. Recommendations for policy and practice are derived from the study's insights, accompanied by a recognition of its limitations and avenues for future research and enhancement in the field of social housing in Nigeria.

An experimental comparison of Predicting customer data in Internet and Mobile Marketing

Currently, the Internet and Mobile technology platforms have gained a lot of popularity in the Nigerian context. Many businesses are seizing the opportunity provided by these platforms to market their goods and services in what is termed ‘e-marketing’. E-Marketing opportunities on these platforms include facebook marketing, twitter marketing, google marketing, whatsapp marketing, youtube marketing, marketing through personal blogs, sms marketing and email marketing, among others. Although these marketing avenues have been engaged by many businesses even with scarce financial resources, the result has been that of little or no corresponding effect on their profit margins. There is therefore the need to predict customer behaviour as regards these marketing avenues so that businesses can know which ones to engage for their marketing activities. This study is therefore aimed at understanding and predicting customer behaviour through correlation analysis and classification techniques in data mining respectively. The results obtained will enable the business community gain an understanding of customer behaviours and engagements on these platforms. Furthermore, the loss on marketing investments by businesses will be minimized leading to increase in business profit margins as businesses make target marketing through the stated channels efficiently

Adolescents and HIV-related behaviour in Nigeria: does knowledge of HIV/AIDS promote protective sexual behaviour among sexually active adolescents?

HIV/AIDS prevalence among Nigerian youth remains one of the highest in the world. Although studies confirmed a high knowledge of HIV among Nigerian youth, there is a lag in linking HIV/AIDS knowledge with protective sexual behaviour. The study utilized data from the Nigeria 2007 National HIV/AIDS and Reproductive Health Survey (NARHS). Analysis was on 865 sexually active adolescents. About 75% of adolescents had good knowledge of HIV/AIDS. Logistic regression models showed that HIV knowledge was significant predictor of non-use of condom (OR=2.34; p=0.041) and accepting gifts for sex (OR=2.02 p=0.043) among male, and predictor of multiple sexual partners (OR=1.30; p=0.023) among females. Regardless of HIV knowledge, higher education, older age at first sex, higher wealth index and urban residency are significant predictors of engagement in non-protective sexual behaviour. The study concludes that high knowledge of HIV/AIDS is not statistically significant in HIV protective attitudes among adolescents

The Impact of Knowledge-Based Trust (Kbt) on The Adoption and Acceptability of Cashless Economy in Nigeria

The introduction of cashless policy in Nigeria had gained a number of reactions over the adoption of cashless economy (or cashless banking). The implication of this is that not many people have the understanding of the benefits the cashless system would accrue to entire Nigerian populace. Although, many have argued that the technological infrastructures available for the implementation of the cashless economy is still a matter of concern. This study attempts to examine the impact of integrating Technology Acceptance Model (TAM) with Knowledge-based Trust (KBT) on the adoption and acceptance of cashless economy among Nigerian populace. We designed a paper-based questionnaire to harvest people’s view about their intention on the adoption of cashless economy in Nigeria as well as their readiness to accept the policy. Consequent upon the impact of trust on the acceptability of the cashless economy, we formulated some hypotheses which was analysed with the use of T-statistics. The results of the hypothesis testing indicate that the integration of KBT with TAM has a significant relationship on intention towards the adoption and acceptance of cashless economy in Nigeria

Audit of insulin prescription patterns and associated burden among diabetics in a tertiary health institution in Nigeria

Background: Insulin is one of the most important anti-diabetic agents in the management of diabetes even among type 2 diabetic. Objective: There was need to assess insulin adherence, mode of insulin delivery and burden of insulin usage among diabetics.Methods: A cross-sectional, prospective questionnaire, orally administered at a Diabetes Clinic of a University Teaching Hospital, SouthWest, Nigeria. Participants were consecutive patients with diabetes who were 18 years or older presently on insulin either alone or in combination with other anti-diabetic agents for at least 3 months. Baseline demographic and insulin treatment information were obtained.Results: Two hundred and thirteen (213) participants were studied. Of these, 21 (9.9%) had T1DM and 192 (90.1%) had T2DM, (means age, 58.6 ± 13.1 years, mean duration of diabetes, 7.0 ± 6.9 years). Insulin adherence was noted in 72.8% with better adherence among those who self-injected insulin compared to those who were injected by health care professionals (HCPs) or relations. Among the respondents, 80.8% were on human insulin and pre-mixed insulin was the most commonly used form of insulin (52.6%). Most participants (52.6%) were taking 10-20 units per day, only 22 (10.3%) were on >40units/day. Reuse of insulin needle was found in 74.6% of the participants.  Major reasons for insulin omission were non-availability of insulin and patients being tired of insulin injection.Conclusion: The insulin adherence among diabetics in this study was high. Non-availability of insulin, insulin injection pain and being tired of continual insulin usage were some of the reasons for non-adherent to insulin usage.Keywords: Adherence, diabetes, burden, insulin injection, omission
