Lecturers’ Assessment of Teaching Practice Exercise in Nigerian Universities

Teaching Practice is a crucial aspect of teacher education. Despite its importance, the programme is confronted with numerous challenges. Consequently, this paper examines the quality of teaching practice in Nigerian Universities from the perspective of education lecturers. Quality of Teaching Practice Questionnaire (QTPQ) was employed in obtaining data from 691 randomly selected education lecturers from the universities across the six geo-political zones in Nigeria. The data obtained were analysed using descriptive and inferential statistics. The study revealed that the respondents rated the quality of teaching practice exercise in Nigerian universities as fairly above average. It was also found that experience and job status had significant influence on the respondents’ assessment, while gender had no influence. Among others, it was recommended that more time should be allotted to teaching practice and re-training programmes should be organised for lecturers on the best practice in the internship aspect of teacher education.

Global fertility in 204 countries and territories, 1950–2021, with forecasts to 2100: a comprehensive demographic analysis for the Global Burden of Disease Study 2021

Background: Accurate assessments of current and future fertility—including overall trends and changing population age structures across countries and regions—are essential to help plan for the profound social, economic, environmental, and geopolitical challenges that these changes will bring. Estimates and projections of fertility are necessary to inform policies involving resource and health-care needs, labour supply, education, gender equality, and family planning and support. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 produced up-to-date and comprehensive demographic assessments of key fertility indicators at global, regional, and national levels from 1950 to 2021 and forecast fertility metrics to 2100 based on a reference scenario and key policy-dependent alternative scenarios. Methods: To estimate fertility indicators from 1950 to 2021, mixed-effects regression models and spatiotemporal Gaussian process regression were used to synthesise data from 8709 country-years of vital and sample registrations, 1455 surveys and censuses, and 150 other sources, and to generate age-specific fertility rates (ASFRs) for 5-year age groups from age 10 years to 54 years. ASFRs were summed across age groups to produce estimates of total fertility rate (TFR). Livebirths were calculated by multiplying ASFR and age-specific female population, then summing across ages 10–54 years. To forecast future fertility up to 2100, our Institute for Health Metrics and Evaluation (IHME) forecasting model was based on projections of completed cohort fertility at age 50 years (CCF50; the average number of children born over time to females from a specified birth cohort), which yields more stable and accurate measures of fertility than directly modelling TFR. CCF50 was modelled using an ensemble approach in which three sub-models (with two, three, and four covariates variously consisting of female educational attainment, contraceptive met need, population density in habitable areas, and under-5 mortality) were given equal weights, and analyses were conducted utilising the MR-BRT (meta-regression—Bayesian, regularised, trimmed) tool. To capture time-series trends in CCF50 not explained by these covariates, we used a first-order autoregressive model on the residual term. CCF50 as a proportion of each 5-year ASFR was predicted using a linear mixed-effects model with fixed-effects covariates (female educational attainment and contraceptive met need) and random intercepts for geographical regions. Projected TFRs were then computed for each calendar year as the sum of single-year ASFRs across age groups. The reference forecast is our estimate of the most likely fertility future given the model, past fertility, forecasts of covariates, and historical relationships between covariates and fertility. We additionally produced forecasts for multiple alternative scenarios in each location: the UN Sustainable Development Goal (SDG) for education is achieved by 2030; the contraceptive met need SDG is achieved by 2030; pro-natal policies are enacted to create supportive environments for those who give birth; and the previous three scenarios combined. Uncertainty from past data inputs and model estimation was propagated throughout analyses by taking 1000 draws for past and present fertility estimates and 500 draws for future forecasts from the estimated distribution for each metric, with 95% uncertainty intervals (UIs) given as the 2·5 and 97·5 percentiles of the draws. To evaluate the forecasting performance of our model and others, we computed skill values—a metric assessing gain in forecasting accuracy—by comparing predicted versus observed ASFRs from the past 15 years (2007–21). A positive skill metric indicates that the model being evaluated performs better than the baseline model (here, a simplified model holding 2007 values constant in the future), and a negative metric indicates that the evaluated model performs worse than baseline. Findings: During the period from 1950 to 2021, global TFR more than halved, from 4·84 (95% UI 4·63–5·06) to 2·23 (2·09–2·38). Global annual livebirths peaked in 2016 at 142 million (95% UI 137–147), declining to 129 million (121–138) in 2021. Fertility rates declined in all countries and territories since 1950, with TFR remaining above 2·1—canonically considered replacement-level fertility—in 94 (46·1%) countries and territories in 2021. This included 44 of 46 countries in sub-Saharan Africa, which was the super-region with the largest share of livebirths in 2021 (29·2% [28·7–29·6]). 47 countries and territories in which lowest estimated fertility between 1950 and 2021 was below replacement experienced one or more subsequent years with higher fertility; only three of these locations rebounded above replacement levels. Future fertility rates were projected to continue to decline worldwide, reaching a global TFR of 1·83 (1·59–2·08) in 2050 and 1·59 (1·25–1·96) in 2100 under the reference scenario. The number of countries and territories with fertility rates remaining above replacement was forecast to be 49 (24·0%) in 2050 and only six (2·9%) in 2100, with three of these six countries included in the 2021 World Bank-defined low-income group, all located in the GBD super-region of sub-Saharan Africa. The proportion of livebirths occurring in sub-Saharan Africa was forecast to increase to more than half of the world's livebirths in 2100, to 41·3% (39·6–43·1) in 2050 and 54·3% (47·1–59·5) in 2100. The share of livebirths was projected to decline between 2021 and 2100 in most of the six other super-regions—decreasing, for example, in south Asia from 24·8% (23·7–25·8) in 2021 to 16·7% (14·3–19·1) in 2050 and 7·1% (4·4–10·1) in 2100—but was forecast to increase modestly in the north Africa and Middle East and high-income super-regions. Forecast estimates for the alternative combined scenario suggest that meeting SDG targets for education and contraceptive met need, as well as implementing pro-natal policies, would result in global TFRs of 1·65 (1·40–1·92) in 2050 and 1·62 (1·35–1·95) in 2100. The forecasting skill metric values for the IHME model were positive across all age groups, indicating that the model is better than the constant prediction. Interpretation: Fertility is declining globally, with rates in more than half of all countries and territories in 2021 below replacement level. Trends since 2000 show considerable heterogeneity in the steepness of declines, and only a small number of countries experienced even a slight fertility rebound after their lowest observed rate, with none reaching replacement level. Additionally, the distribution of livebirths across the globe is shifting, with a greater proportion occurring in the lowest-income countries. Future fertility rates will continue to decline worldwide and will remain low even under successful implementation of pro-natal policies. These changes will have far-reaching economic and societal consequences due to ageing populations and declining workforces in higher-income countries, combined with an increasing share of livebirths among the already poorest regions of the world.

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Facteurs qui entravent l'acceptation du Conseil et du Test Volontaire (CTV) pour dépister le VIH/SIDA chez la jeunesse dans l'état de Kwara, Nigéria.

HIV/AIDS has become a source of concern all over the world. The concern cannot be isolated from the devastating effects of HIV/AIDS on economic, social, political and technological development of any nation with a high prevalence rate Nigeria is one of the countries with HIV/AIDS prevalence rate of over 4%. Despite this challenge, the patronage of Voluntary Counseling and Testing (VCT) is still very low. This study therefore examined the factors hindering the acceptance of VCT as expressed by youths in Kwara State. A total of 600 youths from the three Senatorial districts in the State were involved in the study. A survey instrument designed by the researchers was used to collect relevant information from the respondents. Among others, the study identified ignorance, poverty, inadequate number of VCT centres, stigma and discrimination as major factors responsible for the low patronage of VCT centres in Kwara State. Gender and religion had no significant influence on the respondents' views while place of residence had significant influence. The implications of the findings to medical practice and counseling were identified and discussed.Le VIH/SIDA est devenu une source d'inquiétude partout dans le monde. On ne peut pas séparer cette inquiétude des effets dévastateurs du VIH/SIDA sur le développement social, politique et technologique de n'importe quel pays qui a un taux de prévalence élevé. Le Nigéria est un des pays qui ont un taux de prévalence de plus de 4%. Malgré ce défi, l'acceptation du CTV reste encore très peu élevée. Cette étude a donc examiné les facteurs qui entravent l'acceptation du CTV, d'après les jeunes gens dans l'état de Kwara. Une population totale de 600 jeunes gens de trois districts sénatoriaux dans l'état ont fait partie de l'étude. L'on s'est servi d'un instrument d'enquête façonné par des chercheurs pour collecter l'information de la part des interviewées. L'étude a identifié, entre autres, l'ignorance, la pauvreté , le nombre insuffisant des centres du CTV, la stigmatisation et la discrimination comme des facteurs responsables de la faible fréquentation des centres du CTV dans l'état de Kwara. Le genre et la religion n'avaient aucune influence considérable sur les opinions des répondants alors que le domicile n'avait pas d'influence significative. Nous avons identifié et discuté les implications de nos résultats sur la pratique médicale et sur le consei

Performance characteristics and blood profile of broiler chickens fed corn-cobs based diets with or without enzyme supplementation

Corn-Cob Meal (CCM) is a waste product derived from maize grain shelling corn cob which constitutes nuisance to the environment and it can be included in poultry diet in order to reduce competition between man and animal. Hence, a 63-day feeding trial was conducted in a completely randomized design to determine performance characteristics and blood profile of broiler chickens fed corn-cobs based diets with or without enzyme supplementation. One hundred and sixty five (165) birds were randomly allotted into five dietary treatment groups; T1 : (0% CCM), T2 (10% CCM without enzyme), T3 (20% CCM without enzyme), T4 (10%  CCM with enzyme), T5 (20% CCM with enzyme) with each treatment comprising three  replicates of eleven birds per replicate. Parameters measured include performance characteristics, haematological and serum biochemical indices. The result revealed that there were no significant difference (P>0.05) on performance characteristics of broiler chicken observed except for Average Daily Feed Intake (ADFI) and the Feed Conversion Ratio (FCR). Birds fed 10% and 20% CCM based diet without enzyme recorded the highest value of ADFI (129.38 g/b/d and 130.85 g/b/d) while birds fed 20% CCM based diet with enzyme supplementation had the best FCR value (2.18). The haematological parameters were not significantly influenced (P>0.05) by the diets except for lymphocytes and heterophil count with the highest lymphocytes value in T2 (68.00%) and the lowest value in T5 (53.67 %).  Birds on T5 had significantly (P<0.05) highest heterophil value (40.67%). The serum biochemical indices were not significantly influenced (P>0.05) by the diets except for aspartate aminotransferase. However, values obtained in this study fell within the normal range recommended for healthy broiler chicken. Based on this result, it can be concluded that CCM with enzyme supplementation can be incorporated into broiler diet up to 20% without any detrimental effect on their performance and blood profile

The effect of washing with water and detergent on increasing the shelf life of pepper (Capsicum annum) on sale at Rimi and Tarauni markets of Kano State, Nigeria

Sample of pepper was collected from two selected vegetable markets and used to determine the most effective method of increasing shelf life of pepper. In the research two treatment methods used by marketers of vegetables washing with water and detergent were compared. The results showed that five fungal colonies were isolated from pepper samples obtained from the study aeas. The five fungal colonies isolated from the two markets have the following frequency of occurrence A. niger 17 ( 28.3 %) A. fumigatus 12 (23.3%), R. stolonifer 12 (20.0%), A. flavus 09(15.05%) and Mucor spp 08 (13.3%). Out of the total 60 fungal colonies isolated in the two markets, more colonies were counted from water wash pepper 37 ( 61.0%), while lower colony counts were recorded from detergent washed pepper in the two locations 23 ( 38.3%). It is clear therefore that, this investigation has established fewer fungal colonies counted from detergent washed samples in the two markets is that washing of pepper with detergent is more effective in increasing the shelf life of pepper by removing the surface contaminant micro-organisms
