Value management explicitly targets to optimize value by providing necessary
functions at the least cost without sacrificing quality and performance. However, the
activities/methods of this technique in emerging economies are here and there
related to informal methodology. Therefore, the occurrence of these activities in an
evolving economy requires investigation. The exploration of the extent to which the
measured variables influenced the latent factors informed the need for this study.
Data was retrieved via self-administered questionnaire from 344 registered and
practicing construction professionals in Nigeria. The data was analyzed using SPSS for
descriptive analysis and Structural Equation Modelling (SEM). Kaiser-Meyer-Olkin
measure of sampling adequacy revealed that the internal consistency of the
developed research instrument was appropriate. Confirmatory factor analysis
indicates satisfactory goodness of fit among acknowledged determinants of the
model. Furthermore, the study revealed three (3) phases of the activities/methods of
value management in the Nigerian construction industry which include: information,
information/function analysis, and creativity/evaluation/development/presentation
phases. This means that value management activities and methods are being
practiced in Nigeria, however not as per the typical methodology or standard. The
need to carry out the practice according to the formal value management
methodology is therefore recommended.

Adeleke AQ, Bahaudin AY, Kamaruddeen AM, Bamgbade JA, Salimon MG, Khan MWA, et al.

Saf Health Work, 2018 Mar;9(1):115-124.
PMID: 30363069 DOI: 10.1016/j.shaw.2017.05.004

Background: Substantial empirical research has shown conflicting results regarding the influence of organizational external factors on construction risk management, suggesting the necessity to introduce a moderator into the study. The present research confirmed whether rules and regulations matter on the relationships between organizational external factors and construction risk management.
Methods: Based on discouragement and organizational control theory, this research examined the effects of organizational external factors and rules and regulations on construction risk management among 238 employees operating in construction companies in Abuja and Lagos, Nigeria. A personally administered questionnaire was used to acquire the data. The data were analyzed using partial least squares structural equation modeling.
Results: A significant positive relationship between organizational external factors and construction risk management was asserted. This study also found a significant positive relationship between rules and regulations and construction risk management. As anticipated, rules and regulations were found to moderate the relationship between organizational external factors and construction risk management, with a significant positive result. Similarly, a significant interaction effect was also found between rules and regulations and organizational external factors. Implications of the research from a Nigerian point of view have also been discussed.
Conclusion: Political, economy, and technology factors helped the construction companies to reduce the chance of risk occurrence during the construction activities. Rules and regulations also helped to lessen the rate of accidents involving construction workers as well as the duration of the projects. Similarly, the influence of the organizational external factors with rules and regulations on construction risk management has proven that most of the construction companies that implement the aforementioned factors have the chance to deliver their projects within the stipulated time, cost, and qualities, which can be used as a yardstick to measure a good project.

Jurnal Psikologi Malaysia, 2017;31:12-20.

The study investigated the effects of flipped and conventional classroom teaching approach on performance and retention ability of advance financial accounting students in Abubakar Tafawa Balewa University Bauchi, Nigeria. The study had three specific objectives and three null hypotheses. Quasiexperimental design of pre-test, post-test I and post-test II was used for the study. The study used an intact class of 76 students that offered advance financial accounting in 2015/2016 academic session in the institution. Three instruments were used for data collection. The instruments were Advance financial accounting Achievement Test (AFAAT), Advance financial accounting Diagnostic Achievement Test I (AFADAT I) and Advance financial accounting Diagnostic Achievement Test II (AFADAT II). The validations of instruments were determined by board of examiners in department of vocational and technology education in Abubakar Tafawa Balewa University, Bauchi. The reliability of the instruments was established using pilot study. The result of the pilot study gave reliability coefficient of 0.79. Data collected from the study were coded into Statistical Package of Social Sciences. The package was used to run t-test statistics for the test of the three null hypotheses at significance level of 0.05. The results shows improvement in the performance and retention ability of students when flipped teaching technique was adopted. It was recommended among others that financial accounting lecturers in Nigerian universities should adopt the use of flipped classroom approach in teaching students by providing students with pre-class materials and assignments prior their classroom activities.

Kazaure, Mansur Ahmed, Abdul Rashid abdullah

The Pertanika Journal of Scholarly Research Reviews, 2018;4(3):89-96.
MyJurnal

Small and medium scale enterprises (SMEs) act as a promoter of economic development of the developed and under developed nations. Developing countries like Nigeria that, require sustainable economic growth and development must pay attention to the SMEs sectors in order to reduce unemployment, poverty and improve the standard leaving of its society. Unfortunately, in Nigeria, SMEs have underperformed despite that, 90% of the Nigerian businesses are small scales but their contribution to the Nigerian GDP is below 10%. The main reason for this low contribution of SMEs to Nigerian GDP could be attribute to poor funding, lack of management expertise and lack of access to modern technology among others, with proper finance the SMEs can acquire modern technology and employed qualified staff. Thus, this paper focuses on crowdfunding as financial option for Nigerian SMEs. However, the paper is a conceptual framework.

The science of the brain and nervous system cuts across almost all aspects of human life and is one of the fastest growing scientific fields worldwide. This necessitates the demand for pragmatic investment by all nations to ensure improved education and quality of research in Neurosciences. Although obvious efforts are being made in advancing the field in developed societies, there is limited data addressing the state of neuroscience in sub-Saharan Africa. Here, we review the state of neuroscience development in Nigeria, Africa's most populous country and its largest economy, critically evaluating the history, the current situation and future projections. This review specifically addresses trends in clinical and basic neuroscience research and education. We conclude by highlighting potentially helpful strategies that will catalyse development in neuroscience education and research in Nigeria, among which are an increase in research funding, provision of tools and equipment for training and research, and upgrading of the infrastructure at hand.

The status of natural radioactivity in Nigerian environments

Olatunji MA, Khandaker MU, Nwankwo VUJ, Idris AM

Radiat Environ Biophys, 2022 Nov;61(4):597-608.
PMID: 36175773 DOI: 10.1007/s00411-022-00993-3

Proper documentation of baseline radiation data of different environments is an important step toward adequate environmental monitoring, and it provides quick means to quantitatively check and determine possible radionuclide contamination by anthropogenic sources. Besides, such documentation is useful for decision making processes, assessment of dose rates to the public, epidemiological studies, and environmental regulations. This review summarizes the results of studies conducted on radioactivity in Nigerian environments. For most soil samples, the levels of radioactivity are well within the world averages of 33, 45, and 420 Bq kg-1 for 226Ra, 232Th and 40K, respectively. Other soil samples from regions such as Abeokuta in the southwest, and Jos in the northcentral have been described as high background radiation areas with radioactivity values comparable with those obtained from known high background radiation areas such as the Odisha (formerly Orissa) coast in India (with values reported as 350, 2,825, and 180 Bq kg-1 for 238U/226Ra, 232Th, and 40K, respectively). In some parts of Nigeria, surface and underground water sources used for drinking and other purposes also present elevated levels of 226Ra above the world range of 0.01 to 0.1 Bq l-1 and the tolerable levels recommended by the World Health Organization and U.S. Environmental Protection Agency. Corresponding radiation doses due to measured radioactivities from different environments were estimated and compared with those reported in similar studies around the world. More so, the human and environmental health hazards that might be associated with the reported radioactivity in different environmental settings are discussed. The present report is expected to support authorities in developing appropriate regulations to protect the public from radiation exposure arising from environmental radioactivity. The report also examines other areas of consideration for future studies to ensure adequate radiation monitoring in Nigeria.

Ya'u A, Saad N, Mas'ud A

Environ Sci Pollut Res Int, 2021 Mar;28(11):13570-13580.
PMID: 33188515 DOI: 10.1007/s11356-020-11608-z

Growing environmental deterioration has caused many countries to tighten their environmental regulations across the globe. Recent studies show that most developed countries enforced stricter environmental regulations creating a pollution haven to developing countries such as Nigeria. Studies show the non-availability of an environmental regulation compliance scale in the energy sectors. The aim of this paper is to validate the effects of environmental regulation compliance scale for oil and gas companies' operations in the Nigerian oil and gas industry. Hence, an adapted questionnaire comprising 11 items was administered to 300 local and multinational oil and gas companies in Nigeria. All the items were subjected to evaluations and validations by eight expert reviewers with cognate experience in oil and gas activities. Evaluation of the reliability and validity of the measures of the environmental regulation scale was performed through confirmatory factor analysis (CFA) using SPSS version 25 and PLS-SEM version 3.8. The results provide evidence that the environmental regulation compliance scale has met the reliability and validity criteria. Consequently, policymakers, practitioners, and researchers can adapt this scale to assess the effects of environmental regulation compliance by companies in different jurisdictions across the globe. This study undoubtedly builds the existing literature and contributes to the subject area; by implication, the validated scale will assist host oil and gas countries with stringent environmental regulations to come up with policies in such a way as to ensure not chasing away the current investors or discouraging prospective ones from investing in their countries.

Dynamic impact of urbanization, economic growth, energy consumption, and trade openness on CO 2 emissions in Nigeria

Ali HS, Law SH, Zannah TI

Environ Sci Pollut Res Int, 2016 Jun;23(12):12435-43.
PMID: 26983914 DOI: 10.1007/s11356-016-6437-3

The objective of this paper is to examine the dynamic impact of urbanization, economic growth, energy consumption, and trade openness on CO 2 emissions in Nigeria based on autoregressive distributed lags (ARDL) approach for the period of 1971-2011. The result shows that variables were cointegrated as null hypothesis was rejected at 1 % level of significance. The coefficients of long-run result reveal that urbanization does not have any significant impact on CO 2 emissions in Nigeria, economic growth, and energy consumption has a positive and significant impact on CO 2 emissions. However, trade openness has negative and significant impact on CO 2 emissions. Consumption of energy is among the main determinant of CO 2 emissions which is directly linked to the level of income. Despite the high level of urbanization in the country, consumption of energy still remains low due to lower income of the majority populace and this might be among the reasons why urbanization does not influence emissions of CO 2 in the country. Initiating more open economy policies will be welcoming in the Nigerian economy as the openness leads to the reduction of pollutants from the environment particularly CO 2 emissions which is the major gases that deteriorate physical environment.

Garba NN, Abdulkadir M, Nasiru R, Saleh MA, Bello S, Khandaker MU, et al.

Isotopes Environ Health Stud, 2023 Mar;59(1):112-125.
PMID: 36735938 DOI: 10.1080/10256016.2023.2172001

Terrestrial gamma radiation dose (TGRD) rates were measured in situ from different locations in Katsina State, Nigeria, using a portable radiation survey metre based on geological formations and soil types. The measured TGRD rates ranged from 45 to 271 nGyh-1 with an average value of 116 ± 1 nGyh-1. Geological formation (silicified sheared rock) and soil type (lithosols and ferruginous crusts and ferruginous tropical soils) appeared to have the highest mean TGRD values of 163 and 134 nGyh-1 with sandstone geological formation and alluvial and hydromorphic soils having the lowest TGRD with values of 80 and 61 nGyh-1, respectively. One way ANOVA results shows that the tested null hypothesis was rejected. Thus, indicating that there exists a strong relationship between the various geological formations, soil types with the measured TGRD values based on the alternate hypothesis. Human health hazard indices like annual effective dose equivalent (AEDE), lifetime outdoor annual equivalent dose, and relative excess lifetime outdoor cancer risk associated with the mean TGRD of the study area were also calculated and found to be 0.711, 9.955 mSv, and 5.79 × 10-4, respectively. These values were higher than the world average values but favourable compared with the safety limits recommended by ICRP.

Afr J Reprod Health, 2022 Apr;26(4):32-41.
PMID: 37584982 DOI: 10.29063/ajrh2022/v26i4.4

This study aimed at determining the factors that influence family planning practice among rural women of Pankshin district in Plateau state, Nigeria. A cross-sectional study using a simple random sampling method was conducted from October to December 2019. A self-administered questionnaire was used for data collection among 302 respondents. Among respondents, 48.3% had practised family planning and the most popular family planning method ever practised was injectables (57.5%). The determinants of family planning practice were age group 29-39 and 40-49 years old (AOR=4.373, p <0.001; AOR=5.862, p <0.001), discussion with partner (AOR=9.192, p <0.001) and partner's approval (AOR=2.791, p=0.007). Findings showed an encouraging family planning prevalence with the main determinants involving male partners. Further efforts need to be made to promote family planning practice among male partners and to empower women of all reproductive age groups by providing them with relevant information that is needed for them to make informed decisions.

Adegoye GA, Tolar-Peterson T, Ene-Obong HN, Nuntah JN, Pasqualino MM, Mathews R, et al.

Int J Environ Res Public Health, 2023 Mar 10;20(6).
PMID: 36981799 DOI: 10.3390/ijerph20064891

INTRODUCTION: fish can be an affordable and accessible animal-source food in many Low- and Middle-Income Countries (LMIC).
BACKGROUND: Traditional fish processing methods pose a risk of exposing fish to various contaminants that may reduce their nutritional benefit. In addition, a lack of literacy may increase women fish processors' vulnerability to malnutrition and foodborne diseases.
OBJECTIVE: The overall aim of the project was to educate women and youth fish processors in Delta State, Nigeria about the benefit of fish in the human diet and to develop low literacy tools to help them better market their products. The objective of this study was to describe the development and validation of a low-literacy flipbook designed to teach women fish processors about nutrition and food safety.
METHOD: developing and validating instructional material requires understanding the population, high-quality and relevant graphics, and the involvement of relevant experts to conduct the content validation using the Content Validity Index (CVI) and the index value translated with the Modified Kappa Index (k).
RESULT: The Item-level Content Validity Index (I-CVI) value of all domains evaluated at the initial stage was 0.83 and the Scale-level Content Validity Index (S-CVI) was 0.90. At the final stage, the material was validated with CVI 0.983 by four experts and satisfied the expected minimum CVI value for this study (CVI ≥ 0.83, p-value = 0.05). The overall evaluation of the newly developed and validated flipbook was "excellent".
CONCLUSIONS: the developed material was found to be appropriate for training fish processors in Nigeria in nutrition and food safety and could be modified for a population of fish processors in other LMICs.

Effectiveness of health education module on work safety culture in improving knowledge, attitudes and practices: a cluster randomized controlled trial among public sector administrative workers in Nigeria

Odu JO, Hamedon TR, Mahmud A, Baharudin R

Med J Malaysia, 2023 May;78(3):308-317.
PMID: 37271840

INTRODUCTION: Studies have shown that a workplace safety culture (WSC) is lacking among the general workforce in Nigeria. Poor WSC can adversely impact workers' health and high remedial costs for employers. To improve WSC, workers need to improve related knowledge, attitude, and practices (KAP) towards WSC through effective health interventional programs at the workplace. The main objective of this study is to develop, implement and evaluate the effectiveness of the Work Safety Culture Health Education Module (WSCHEM). The specific goals are to improve KAP related to office ergonomics towards WSC among public sector administrative workers in Abeokuta, Nigeria MATERIALS AND METHODS: The study was a two-armed, singleblinded cluster randomised controlled trial (CRCT) involving 247 public sector administrative workers from clusters of 20 ministries in Abeokuta, Southwestern Nigeria. The intervention group was given WSCHEM, whereas the waitlist group received a seminar on team building and leadership skills and received the WSCHEM after the intervention program ended. The evaluation was done three times using the first formal validated, self-administered Work Safety Culture Questionnaire (WSCQ) among the administrative workers: first at baseline, second at 1 month, and third at 3 months post-intervention.
RESULT: The results showed no statistically significant differences between groups regarding the respondents' characteristics (socio-demographic and occupational/officerelated ergonomic factors) and the outcome variables KAP towards WSC at baseline. For practices towards WSC, both intervention (β 6.8, 95%CI 4.85, 8.72) and time (β 6.2, 95%CI 4.49, 7.94) significantly improved the respondents' practices towards WSC in the per-protocol analysis. In the secondary outcomes, both knowledge of WSC, intervention (β 3.5, 95%CI 2.8, 4.2) and time (β 3.4, 95%CI 2.7, 5.9); and attitudes towards WSC, intervention (β1.7, 95%CI 1.25, 2.23) and time (β 2.3, 95%CI 1.92, 2.76) significantly improved the respondents' level of knowledge and attitudes respectively towards WSC.
CONCLUSION: The intervention, WSCHEM, was effective in improving the administrative workers' KAP towards WSC, as demonstrated by the significance between and within-group differences.

Afr Health Sci, 2023 Mar;23(1):255-261.
PMID: 37545927 DOI: 10.4314/ahs.v23i1.27

OBJECTIVE: We evaluated the susceptibility status of Anopheles gambiae in two communities of Ikorodu, Lagos, Nigeria to DDT, deltamethrin, lambda cyhalothrin and bendiocarb.
METHODS: Anopheles immature stages were collected from their habitats in the surveyed community and allowed to emerge before exposure adult females to discriminating doses of WHO insecticides including DDT, deltamethrin, lambda cyhalothrin, bendiocarb and malathion. PBO synergistic bioassay was conducted for insecticides where the mosquito samples showed resistance. PCR assay was used for the detection of kdr mutation in the mosquitoes.
RESULTS: Resistance to DDT (40% and 86%) and lambda cyhalothrin (75% and 84%) in Oke-Ota and Majidun respectively. Suspected resistance to deltamethrin (94.9%) and bendiocarb (93.5%) was recorded in Oke-Ota community and the mosquitoes were susceptible to malathion in both communities. KDR mutation (L1014F) from resistance samples from both locations though with a low frequency that significantly departs from Hardy-Weinberg's probability (P> 0.01). PBO synergized bioassay was able to increase knockdown, percentage mortality and restore full susceptibility to deltamethrin and bendiocarb.
CONCLUSION: Results from this study indicates that the metabolic resistance mechanism is highly implicated in the resistance to different classes of insecticide in Ikorodu and this should be taken into consideration when implementing vector control activities in this area.

Effects of an educational intervention on Nigerian midwives' intention to provide planned home birth care

Muhammed A, Shariff-Ghazali S, Md Said S, Hassan M, Lee K

Birth, 2023 Sep;50(3):587-595.
PMID: 36226886 DOI: 10.1111/birt.12681

BACKGROUND: The majority of women in Sokoto, Nigeria prefer homebirths, but midwives are reluctant to provide care in the home setting. As such, many women continue to give birth at home alone or assisted by untrained attendants, which is associated with an increased risk for maternal and neonatal morbidity and mortality.
METHODS: A randomized controlled trial was conducted among 226 midwives from 10 health care facilities. The intervention group received an educational program on home birth. A validated questionnaire that evaluated knowledge, attitudes, norms, perceived control, and intention to provide planned home birth care was given at baseline, immediately after the intervention, and at three-months follow-up. Data were analyzed using linear mixed-effect model statistics.
RESULTS: Following the intervention, the intervention group demonstrated higher knowledge and more positive attitudes, norms, perceived control, and intention to provide planned home birth care compared with the control group (P 0.05).
DISCUSSION: Educating midwives on planned home birth increases their willingness to provide planned home birth care. Health system administrators, policymakers, and researchers may use similar interventions to promote skilled home birth attendance by midwives. Increasing the number of midwives who are willing to attend planned home births provides women at low risk for medical complications with safer options for labor, delivery, and postpartum care.

Influences of women empowerment indices on demand for childcare services: Evidence from the Nigeria Demographic and Health Surveys

Dejun Z, Remi RA, Mouchun Y, Romanus O, Mihajlo J

Afr J Reprod Health, 2023 Oct 31;27(10):65-80.
PMID: 37915165 DOI: 10.29063/ajrh2023/v27i10.6

This study examined the effect of various dimensions of women's empowerment on childcare use in Nigeria, utilizing information from five rounds of the National Demographic and Health Surveys. The analysis made use of both binary and multinomial logistic regression. The findings show that women who share household choices with their spouses were more likely to undertake postnatal care for their babies in either private or public hospitals compared to self-medication/others/traditional. Also, women who owned houses and those who participate in economic activities are significantly more inclined to use postnatal services for babies in health facilities. By implication, women empowerment is a significant factor to consider in improving childcare services in Nigeria. This suggests that in order to improve the health of children, women's inputs in household decision-making should be accommodated, while efforts should be made to enhance household socioeconomic position, and support mothers to have formal education. The findings also suggest that promoting women's empowerment can play a crucial role in increasing the demand for formal childcare services.

Selecting the optimal gridded climate dataset for Nigeria using advanced time series similarity algorithms

Tanimu B, Hamed MM, Bello AD, Abdullahi SA, Ajibike MA, Shahid S

Environ Sci Pollut Res Int, 2024 Feb;31(10):15986-16010.
PMID: 38308777 DOI: 10.1007/s11356-024-32128-0

Choosing a suitable gridded climate dataset is a significant challenge in hydro-climatic research, particularly in areas lacking long-term, reliable, and dense records. This study used the most common method (Perkins skill score (PSS)) with two advanced time series similarity algorithms, short time series distance (STS), and cross-correlation distance (CCD), for the first time to evaluate, compare, and rank five gridded climate datasets, namely, Climate Research Unit (CRU), TERRA Climate (TERRA), Climate Prediction Center (CPC), European Reanalysis V.5 (ERA5), and Climatologies at high resolution for Earth's land surface areas (CHELSA), according to their ability to replicate the in situ rainfall and temperature data in Nigeria. The performance of the methods was evaluated by comparing the ranking obtained using compromise programming (CP) based on four statistical criteria in replicating in situ rainfall, maximum temperature, and minimum temperature at 26 locations distributed over Nigeria. Both methods identified CRU as Nigeria's best-gridded climate dataset, followed by CHELSA, TERRA, ERA5, and CPC. The integrated STS values using the group decision-making method for CRU rainfall, maximum and minimum temperatures were 17, 10.1, and 20.8, respectively, while CDD values for those variables were 17.7, 11, and 12.2, respectively. The CP based on conventional statistical metrics supported the results obtained using STS and CCD. CRU's Pbias was between 0.5 and 1; KGE ranged from 0.5 to 0.9; NSE ranged from 0.3 to 0.8; and NRMSE between - 30 and 68.2, which were much better than the other products. The findings establish STS and CCD's ability to evaluate the performance of climate data by avoiding the complex and time-consuming multi-criteria decision algorithms based on multiple statistical metrics.

Fulltext Predictors of poststroke health-related quality of life in Nigerian stroke survivors: a 1-year follow-up study

Hamza AM, Al-Sadat N, Loh SY, Jahan NK

Biomed Res Int, 2014;2014:350281.
PMID: 24982864 DOI: 10.1155/2014/350281

This study aims to identify the predictors in the different aspects of the health-related quality of life (HRQoL) and to measure the changes of functional status over time in a cohort of Nigerian stroke survivors. A prospective observational study was conducted in three hospitals of Kano state of Nigeria where stroke survivors receive rehabilitation. The linguistic-validated Hausa versions of the stroke impact scale 3.0, modified Rankin scale, Barthel index and Beck depression inventory scales were used. Paired samples t-test was used to calculate the amount of changes that occur over time and the forward stepwise linear regression model was used to identify the predictors. A total of 233 stroke survivors were surveyed at 6 months, and 93% (217/233) were followed at 1 year after stroke. Functional disabilities were significantly reduced during the recovery phase. Motor impairment, disability, and level of depression were independent predictors of HRQoL in the multivariate regression analysis. The involvement of family members as caregivers is the key factor for those survivors with improved functional status. Thus, to enhance the quality of poststroke life, it is proposed that a holistic stroke rehabilitation service and an active involvement of family members are established at every possible level.
