    Accurate and timely evaluation and assessment of emission data and its impact on environmental status has been a key challenge due to the conventional manual approach utilized for independently computing most emission parameters. To resolve this long-standing issue, we proposed an Artificial Intelligence (AI)-driven Decision Tree model to adequately classify Environmental Protection Agency (EPA) status based on multiple Emission Parameters. The model's performance was systematically evaluated using multiple emission parameters obtained from a two-stroke motorcycle dataset collected in Nigeria across various metrics such as K-S Statistics, Confusion Matrix, Correlation Heat Map, Decision Tree, Validation Curve, and Threshold Plot. The K-S Statistics plot's experimental results showed a considerable correlation between HC, CO, and the target variable, with values ranging from 0.75-0.80. At the same time, CO2 and O2 do not correlate with the target variable with values between 0.00 and 0.09. The Confusion Matrix revealed that the proposed model has an overall accuracy of 99.9% with 481 true positive predictions and 75 true negative predictions, indicating the effectiveness of the proposed AI-driven model. In conclusion, our proposed AI-driven model can effectively classify EPA status based on multiple emission parameters with high accuracy, which may spur positive advancement in policy enhancement for proper environmental management

    Adapted motivational interviewing to improve the uptake of treatment for glaucoma in Nigeria: study protocol for a randomized controlled trial.

    BACKGROUND: Glaucoma is a chronic eye disease associated with irreversible visual loss. In Africa, glaucoma patients often present late, with very advanced disease. One-off procedures, such as laser or surgery, are recommended in Africa because of lack of or poor adherence to medical treatment. However, acceptance of surgery is usually extremely low. To prevent blindness, adherence to treatment needs to improve, using acceptable, replicable and cost-effective interventions. After reviewing the literature and interviewing patients in Bauchi (Nigeria) motivational interviewing (MI) was selected as the intervention for this trial, with adaptation for glaucoma (MIG). MI is designed to strengthen personal motivation for, and commitment to a specific goal by eliciting and exploring a person's reasons for change within an atmosphere of acceptance and compassion. The aim of this study is to assess whether MIG increases the uptake of laser or surgery amongst glaucoma patients where this is the recommended treatment. The hypothesis is that MIG increases the uptake of treatment. This will be the first trial of MI in Africa. METHODS: This is a hospital based, single centre, randomized controlled trial of MIG plus an information sheet on glaucoma and its treatment (the latter being "standard care") compared with standard care alone for glaucoma patients where the treatment recommended is surgery or laser.Those eligible for the trial are adults aged 17 years and above who live within 200 km of Bauchi with advanced glaucoma where the examining ophthalmologist recommends surgery or laser. After obtaining written informed consent, participants will be randomly allocated to MIG plus standard care, or standard care alone. Motivational interviewing will be delivered in Hausa or English by one of two MIG trained personnel. One hundred and fifty participants will be recruited to each arm. The primary outcome is the proportion of participants undergoing laser or surgery within two months of the date given to re attend for the procedure. MIG quality will be assessed using the validated MI treatment integrity scale. DISCUSSION: Motivational interviewing may be an important tool to increase the acceptance of treatment for glaucoma. The approach is potentially scalable and may be useful for other chronic conditions in Africa. TRIAL REGISTRATION: ISRCTN79330571 (Controlled-Trials.com)

    Patency of the Ductus Arteriosus in Newborns: Experience in a Special Care Baby Unit

    A prospective cohort study of infants admitted into the Special Care Baby Unit, University College Hospital, Ibadan, has revealed a 24.5 per cent prevalence of patency of the ductus arteriosus (PDA) among 97 infants, who were admitted over a six-month period. The major factor predisposing to PDA was prematurity (p=0.014). A higher incidence of PDA (35 per cent) was found among the preterm infants, and of these preterm infants, the very low birth weight (VLBW) infants were found to be more highly susceptible to PDA (p = 0.028). The mean birth weight of the preterm infants who developed PDA in the study was 1447g, while that of those preterm infants without PDA was 1835g. There was no relationship between the sex of the infants and the development of PDA. A strong association was however, found between respiratory distress and PDA (

    The external impacts of Central Bank independence Os impactos externos da independência dos Bancos Centrais

    The term "central bank independence" (or abbreviated, CBI) can be broadly defined as the degree of freedom of the central bank to pursue monetary policy without interference from political considerations. The idea of central bank independence has been widely accepted over the last several decades by many countries around the world, both developed and developing. Since being first written about academically in the late 1980s, many countries have come to adopt this policy and many governments have come to recognize this as standard procedure. As such, many countries around the world granted autonomy to their central banks during the 1980s and 1990s. The majority of past studies have examined primarily the impact of central bank independence on inflation. however, the additional theoretical benefits are much more far reaching, the result of a more stable and prosperous macroeconomic environment. Additionally, there is only now sufficient data to empirically determine whether many of these claims are true. This study examines central bank independence in developing countries of Latin America and Asia as well as selected developed countries to determine what actual impact an autonomous central bank has had. It also examines such phenomena as financial crises (including the current global crisis of 2008-2009), inflation targeting, legal systems, country development and fiscal policy to determine the effects of these items on not only inflation, but the broad spectrum of macroeconomic outcomes. Although there is some empirical evidence to support the benefits of central bank independence, it is limited in scope to certain areas.<br>O termo "independência do banco central" (ou IBC) pode ser amplamente definido como o grau de liberdade que o banco central possui para seguir sua política monetária sem a interferência de considerações políticas. A ideia da independência do banco central foi aceita nas últimas décadas por muitos países ao redor do mundo, tanto desenvolvidos como em desenvolvimento. Desde a primeira literatura acadêmica a respeito no final dos anos 80, muitos países começaram a adotar essa política e muitos governos a reconheceram como padrão. Assim, muitos países ao redor do mundo concederam autonomia a seus bancos centrais nos anos 80 e 90. A maior parte dos estudos existentes investigou principalmente o impacto da independência do banco central na inflação. Porém, os benefícios teóricos adicionais vão muito além, resultado de um ambiente macroeconômico mais estável e próspero. Ademais, somente agora há dados suficientes para a determinação empírica da veracidade de muitas dessas alegações. Este estudo investiga a independência dos bancos centrais em países em desenvolvimento na América Latina e na Ásia, além de determinados países desenvolvidos, para determinar o real impacto de um banco central autônomo. Também examina fenômenos como crises financeiras (inclusive a crise global em curso no período 2008-2009), estabelecimento de metas de inflação, sistemas legais, desenvolvimento dos países e política fiscal para determinar os efeitos destes itens não somente na inflação, mas no espectro amplo de resultados macroeconômicos. Apesar de haver evidências empíricas para apoiar os benefícios da independência do banco central, seu escopo é limitado a determinadas áreas
