Iron-impregnated filter paper (Fe-Pi) was evaluated as phosphorus (P) extractant in four soils of Ogun state, southwest Nigeria in a screenhouse experiment. The experiments lasted for 8 weeks. Soil P contents were extracted at 0, 4, and 8 weeks after the incorporation of amendments (cattle manure, poultry manure, and wood ash) using Fe-Pi, Bray-1, Bray-2, Mehlich-1, Hunter, and Olsen extractant. Agronomic variables were taken fortnightly from grown maize plants and later harvested at 8 weeks, residual effects of the treatments were also evaluated. Maize dry matter weight (DMW) and P uptake were also measured. Results indicated that a linear relationship existed among the extractants with significant coefficient at p ≤.001. Fe-Pi established a strong relationship with the conventional extractants in the following order: Bray-1 (R2 = 0.99) > Bray-2 (R2 = 0.98) > Hunter (R2 = 0.96) > Mehlich-1 (R2 = 0.86) > Olsen (R2 = 0.82). Fe-Pi had a significant relationship with P uptake and DMW. Phosphorus uptakes under the animal manure amendments were statistically higher than uptake in control and woodash amended soils. Therefore, the study concluded that Fe-Pi was a good predictor of plant available P and had significant relationship with Bray-1, thus it could be considered for the estimation of soil available P in soils of southwest Nigeria.

Extant studies have focused on exploring the research output of universities in Nigeria, but the measure of the quality of research output using citations per paper (CPP) from the Web of Science (WoS) and Scopus is scarcely discussed. This paper investigated the quality of papers published by the top 76 universities in Nigeria. Five hypotheses on CPP were tested using Kruskal-Wallis and Mann-Whitney tests. These hypotheses tested whether CPP is the same or different i) across six geo-political regions (GPRs), ii) between the two major regions, iii) across three university funding types, iv) in Scopus and WoS, and v) if these two databases are correlated. Results using these two databases indicated that no significant median differences were detected among universities across the six GPRs, between northern and southern Nigeria, and between the three funding types (federal, state, and private). Moreover, no significant median differences in CPP between Scopus and WoS were detected, and CPP in both databases was highly positively correlated (0.879; p = 0.05). A comparison of the mean CPP of Nigeria (5.90) from Scopus with 57 other African countries ranked it 47th despite being ranked third in terms of volume of published articles. Policy prescriptions are made on the implications of using CPP for practice. [ABSTRACT FROM AUTHOR]

This project is focused on the study of some quality characteristics of robust tissue paper a product of Epesok Paper Mills using statistical quality control techniques. Three important quality characteristics are Ph, Basic weight (g/m2) and Absorbency (mm) which are all variable measures. The data used for the study is a secondary data collected from the daily laboratory records of Epesok paper Mills Company of Nigeria for a period of seven (7) months. Control chart was used to monitor the performance of each of the quality characteristics. Also correlation analysis was carried out to determine possible correlation been pairs of the quality characteristics. The results shows that each of the characteristics monitored were statistically under control. Also the results of the correlation analysis confirm significant correlations among some quality characteristics. [ABSTRACT FROM AUTHOR]

Cesarean delivery rates are rapidly increasing in Southeastern Europe (to more than 60%), North Africa (with a rate as high as 72% in Egypt), and in urban areas in Southern Africa (a rate of over 50% in Lagos, Nigeria). Data on the background to these increases are scarce, but likely to include poor birthing facilities in general hospitals, convenience for the doctor, private medicine, fear of litigation, socioeconomic status, shortage of midwives and nurses, and disappearance of vaginal instrumental deliveries. Options to reverse cesarean delivery trends are discussed. In this context there is a need to be better informed about how women are being counseled regarding vaginal or cesarean delivery. The long-term consequences in subsequent pregnancies for mothers and children may well be largely ignored, while these risks are highest in LMICs where higher birth numbers are desired. FIGO has begun discussions with obstetric and gynecologic societies, healthcare bodies, and governments in several countries discussed in this article, to find ways to lower the cesarean delivery rate. The requests came from the countries themselves, which may prove beneficial in helping advance progress., (© 2023 The Authors.

Background: Timely and reliable data are crucial for clinical, epidemiologic, and program management decision making. Electronic health information systems provide platforms for managing large longitudinal patient records. Nigeria implemented the National Data Repository (NDR) to create a central data warehouse of all people living with human immunodeficiency virus (PLHIV) while providing useful functionalities to aid decision making at different levels of program implementation., Objective: We describe the Nigeria NDR and its development process, including its use for surveillance, research, and national HIV program monitoring toward achieving HIV epidemic control., Methods: Stakeholder engagement meetings were held in 2013 to gather information on data elements and vocabulary standards for reporting patient-level information, technical infrastructure, human capacity requirements, and information flow. Findings from these meetings guided the development of the NDR. An implementation guide provided common terminologies and data reporting structures for data exchange between the NDR and the electronic medical record (EMR) systems. Data from the EMR were encoded in extensible markup language and sent to the NDR over secure hypertext transfer protocol after going through a series of validation processes., Results: By June 30, 2021, the NDR had up-to-date records of 1,477,064 (94.4%) patients receiving HIV treatment across 1,985 health facilities, of which 1,266,512 (85.7%) patient records had fingerprint template data to support unique patient identification and record linkage to prevent registration of the same patient under different identities. Data from the NDR was used to support HIV program monitoring, case-based surveillance and production of products like the monthly lists of patients who have treatment interruptions and dashboards for monitoring HIV test and start., Conclusion: The NDR enabled the availability of reliable and timely data for surveillance, research, and HIV program monitoring to guide program improvements to accelerate progress toward epidemic control., Competing Interests: None declared., (The Author(s).

Social workers, especially in the Global North/developed countries such as the United States of America, Australia, Canada, and the United Kingdom, have been actively involved in implementing social programs to improve the psychosocial, health, and wellbeing of older adults during the COVID-19 pandemic. However, this is not the case in the Global South/developing countries like Nigeria, Ghana, etc. This concept paper aims to describe the current state of Nigerian social workers' role in developing and implementing social programs for older adults during the COVID-19 pandemic and to identify action plans for further strengthening their involvement. We systematically reviewed the literature to identify Nigerian social workers' role in developing and implementing social programs for older adults during COVID-19. Our review reflected that social workers are rarely involved in developing and implementing social programs; when involved, their involvement is on a consultation basis, which limits their active involvement in multidisciplinary team of COVID-19 prevention and vaccination ad hoc committees in Nigeria.

Introduction: The instructor-led CPR training method has been used for over 4 decades. However, nurses' knowledge and skills are still low. Instructor-led CPR training is an extremely capital-intensive programme that requires more time, workforce, and space, thus serving as an impediment to effective learning among the prospective nurses' trainees. Self-directed training method is suggested to improve the knowledge and skills of CPR among healthcare practitioners due to the low cost and flexibility. This study aims to evaluate the effectiveness of self-directed method in improving nurses' knowledge and skill retention from baseline to post-test, one, three-, and six months. Method: A two-arm double-blinded randomised controlled trial will be conducted in two referral hospitals. The control group training consists of a one-day session taught by AHA-certified instructors, whereas the intervention group training entails participants learning on computers in a simulation lab for seven days. A generalised estimated equation model will be used for statistical analysis. Discussion: Through the self-directed training method, participants will have significantly better knowledge and skills of CPR compared to the conversational training method across the time points. Self-directed training method is a simple, cost-effective and flexible method, which can facilitate the training of more nurses in the acquisition and retention of knowledge and skills, especially for those who prefer to learn at their own pace.

Wood is versatile, inexhaustible and renewable. These made the wood an outstanding material used in different domain such as raw material for production of pulp, paper and fibre based products. In Nigeria, one of the problems in pulp and paper industry is inadequate supply of long fibre for paper production. Also, overexploitation of materials having desirable fibre characteristic was observed. Therefore, there is need to research into lesser known wood species so as to ascertain its suitability for paper making. This study presents the potential of Aningeria robusta wood as source for adequate fibres for paper making. Samples of 20x20x20mm were collected from the three trees of Aningeria robusta wood at different position; base (10%), middle (50%) and top (90%) along the merchantable height and prepared into slivers of 3mmx10mm for examination of the fibre characteristics. Thereafter, it was macerated and viewed under microscope. Further morphological indices were calculate accordingly. The mean fibre length, fibre diameter, lumen, cell wall thickness (CWT), slenderness, flexural ratio and runkel ratio were 1.55mm, 11.71µm, 8.78µm, 1.46, 132.12, and 75.07 respectively. Variation of indices along sampling heights were not significant except for CWT. A. robusta has shown good properties and could be added to already known wood species suitable for paper making.

Background: Health workers in low- and middle-income countries are increasingly demanded to collect more and more data to report them to higher levels of the health information system (HIS), in detriment of useful data for clinical and public health decision-making, potentially compromising the quality of their health care provison. In order to support health workers' decision-making, we engaged with partners in Côte d'Ivoire, Mozambique and Nigeria in a research project to conceive, design, produce, implement and test paper-based health information tools: the PHISICC tools. Our aim was to understand the use of PHISICC tools by health workers and to improve them based on their feedback., Methods: The design Health Facility Laboratories (HF Labs) in Côte d'Ivoire and in Nigeria were set up after months of use of PHISICC tools. Activities were structured in three phases or 'sprints' of co-creative research. We used a transdisciplinary approach, including anthropology and Human Centered Design (HCD), observations, shadowing, structured interviews and co-creation., Results: Health workers appreciated the standardization of the tools across different health care areas, with a common visual language that optimized use. Several design issues were raised, in terms of formats and contents. They strongly appreciated how the PHISICC registers guided their clinical decision-making and how it facilitated tallying and counting for monthly reporting. However, adherence to new procedures was not universal. The co-creation sessions resulted in modifications to the PHISICC tools of out-patient care and postnatal care., Discussion: Although health systems and systemic thinking allowed the teams to embrace complexity, it was the HCD approach that actually produced a shift in researchers' mind-set: from HIS as data management tools to HIS as quality of care instruments. HCD allowed navigating the complexity of health systems interventions due to its capacity to operate change: it not only allowed us to understand how the PHISICC tools were used but also how to further improve them. In the absence of (or even with) an analytical health systems framework, HCD approaches can work in real-life situations for the ideation, testing and implementation of interventions to improve health systems and health status outcomes., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Ekpenyong, Heitz Tokpa, Nwankwo, O'Donnell, Rodriguez Franco, Berté, Amani Kouassi, Eteng, Undelikwo, Auer, Guessan Bi, Oyo-Ita and Bosch-Capblanch.)

Most educators' inability to provide learning contents that suit different learning styles has caused a lot of problems in terms of performance. Thus, to cater to students' preferences in terms of access to learning contents, the distance learning regulatory body in Nigeria emphasized that course materials should be developed in mixed-media formats. This study was carried out to compare the effects of printed, video, and Moodle-based courseware on educational technology students' achievement, retention, and satisfaction in a distance learning course. A quasi-experimental design was employed for the study involving 108 participants from three experimental groups. The learning content and instruments, subjected to validation and reliability tests, where values of 0.78 and 0.86 were obtained using the Pearson product moment correlation and Cronbach's alpha for achievement and satisfaction inventory, respectively, were administered within a four-week period. Data collected were analyzed using descriptive and inferential statistics. Findings indicated that the printed, video, and Moodle-based courseware formats improved students' achievement with mean gain scores of 47.92, 40.89, and 43.03, respectively. A significant difference was observed in the achievement (F [subscript (2,104)] = 8.67, p < 0.05), retention (F [subscript (2,104)] = 29.406, p < 0.05), and satisfaction scores (F [subscript (2,104)] = 5.662, p < 0.05) of the three groups. Open and distance learning administrators in Nigeria are recommended to produce and deploy printed, video, and Moodle-based formats of courseware to meet different students' learning preferences.

Background: Health information systems (HIS) are meant to support decision-making at all levels of the system, including frontline health workers. In field studies in Côte d'Ivoire, Mozambique and Nigeria, we observed health workers' interactions with the HIS and identified twelve decision-making components of HIS. The objective of this framework synthesis is to portray these components in HIS research, in order to inform the ideation of a paper-based HIS intervention (PHISICC)., Methods: We searched studies in the Cochrane Central Register of Controlled Trials (CENTRAL), Embase, Epistemonikos, Medline, in-Process on the Ovid platform, OpenGrey, PDQ  Evidence ("pretty darnd quick" Evidence), the World Health Organization (WHO) Global Health Library and included studies focussing on HIS interventions, data quality, information support tools and data use for decision-making in the context of the governmental health care sector. We assessed the methodological quality of studies using the Critical Appraisal Skills Programme tool. We synthesised the findings based on the decision-making components of HIS and thematic areas., Results: The search identified 6784 studies; 50 were included. Most of the 50 studies had quality concerns. All studies included at least one of the decision-making components: the most prominent were the technical aspects of 'recording' and 'reporting'. Data use for decision-making was much less represented., Conclusion: HIS research focuses on the more technical aspects of HIS. Further research on HIS, given the strong push towards HIS digitalisation, should consider putting at the centre the human experience of decision-making and data use, in order to make HIS relevant for quality of care., (© 2022 The Authors.

The study investigated the perceived role of digital theological library and term paper counselling in undergraduate religious education students' academic success in the federal universities in southeast Nigeria. The study adopted a descriptive survey design. A structured questionnaire developed by the researchers was used for data collection. 166 undergraduate religious education students were chosen as respondents in this research. The results showed that items on the perceived role of digital theological library and term paper counselling were all accepted by the students as means of achieving academic success. There was a significant difference in the perceived role of the digital theological library in achieving academic success among religious education students by the university. There was a significant difference in the perceived role of term paper counselling in achieving academic success among religious education students based on university. There was also a significant difference in the perceived role of university librarians in achieving academic success among religious education students based on university. The researchers noted that these findings have implications for university librarians across the universities and it was recommended that the use of digital theological libraries for academic purposes and term paper counselling should be strengthened.

The study investigated religious education students' awareness and use of theological commons for term paper writing and research in the federal universities in southeast Nigeria. The study adopted a descriptive survey design to investigate 96 male students and 86 female students. The statistical analysis was done using an independent t-test at 0.05 level of significance. The finding of this study showed that there is no significant difference in the awareness of theological commons among religious education students for term paper writing and research by gender. The finding of this study also showed that there is a gender difference in the use of theological commons for term paper writing and research among religious education students. It was recommended that there should be seminars and workshops to intensify the use of theological commons among the students for term paper writing and improved research skills.

This replication study tests the repeatability of the study conducted by Adelaja and George (2019a) on the relation between Boko Haram related events of armed conflict and agricultural land use decisions. For the computational reproduction of the original results, we used the same datasets and the same methodological approach. Yet, our findings substantially deviate from the results in the original study. To test the robustness of our own results, we applied comprehensive robustness checks, such as using a different measure for armed conflict, including an additional survey wave of the GHS panel data, and applying two different timewise merging procedures. The results of the robustness checks were very sensitive to changes in the underlying data. Hence, we question the internal validity of the study's findings and argue that there is most likely a more general mismatch between the data, the methodology and the research questions. The bottom-line of this study is not that there are computable differences between Adelaja and George (2019a) and our estimations, but rather that caution should be taken in deriving policy implications from Adelaja and George (2019a) as their results lack internal validity.

Background: Africa is the global region where modern-slavery is most prevalent, especially among women and girls. Despite the severe health consequences of human trafficking, evidence on the risks and experiences of trafficked adolescents and young women is scarce for the region. This paper addresses this gap by exploring the intersections between violence, migration and exploitation among girls and young women identified as trafficking survivors in Nigeria and Uganda., Methods: We conducted secondary analysis of the largest routine dataset on human trafficking survivors. We used descriptive statistics to report the experiences of female survivors younger than 25 years-old from Nigeria and Uganda. We also conducted 16 semi-structured interviews with adolescents identified as trafficked in both countries. We used thematic analysis to explore participants' perceptions and experiences before, during and after the trafficking situation., Results: Young female survivors of human trafficking in Nigeria and Uganda are exposed to a range of experiences of violence before migration, during transit and at destination. The qualitative data revealed that children and adolescents migrated to escape family poverty, violence and neglect. They had very low levels of education and most had their studies interrupted before migrating. Family members and close social contacts were the most common intermediaries for their migration. During transit, sexual violence and hunger were common, especially among Nigerians. Participants in both the quantitative and qualitative studies reported high levels of violence, deception, coercion, withheld wages and poor working conditions at destination. The adolescents interviewed in the qualitative study reported severe mental suffering, including suicide attempts. Only one reported the prosecution of perpetrators., Conclusions: Our findings suggest that interventions to prevent or mitigate the negative impact of adverse childhood experiences can contribute to preventing the trafficking of adolescents in Nigeria and Uganda. These interventions include social protection mechanisms, universal access to education, social service referrals and education of parents and carers. Importantly, effective prevention also needs to address the systemic conditions that makes trafficking of female adolescents invisible, profitable and inconsequential for perpetrators., (© 2022.

The paper examined the challenges of maintenance of paper based archival information materials and strategies for enhancement in academic libraries in South East, Nigeria which doubled as the objectives of the study. Descriptive survey research method was used for the study. The population consisted of 277 library staff in academic libraries of government owned institutions. Questionnaire and structured interview guide was used to collect data which was analyzed using the Statistical Package of Social Sciences (SPSS) version 20. Mean scores and standard deviation were used to analyze data generated for the two research questions while ttest was used for the hypothesis. Real limits of numbers were used to determine the bench mark. The major findings of the study showed the challenges involved in maintenance of archival materials to include inadequate funding and tropical climate that breeds insects. The strategies involved in archival maintenance practices include: recruiting adequate personnel in libraries, provision of maintenance policies, adequate funding of libraries for proper maintenance of archives, proper control of insect by the use of insecticides and adequate training of maintenance personnel. The hypothesis tested revealed that there is no significant difference in the mean ratings between the male and female library staff in respect to strategies for maintenance practices of paper based archival paper materials in the academic libraries. The paper recommended that the library administrators should engage qualified and competent staff on the field of Library and Information Science and ICT to ensure adequate maintenance of archival materials in academic libraries.

The authors assessed the potential of Nigerian currency notes to act as environmental vehicles for the transmission of pathogenic parasites and bacteria. Currency notes obtained from four major cities in Nigeria were evaluated according to standard techniques. Fifty-four (21.6 percent [95 percent CI: 16.50-26.70]) of the first batch of 250 notes, which underwent parasitological analysis, were contaminated with enteric parasites; 133 (53.2 percent [95 percent CI: 47.02-59.39]) of the second batch of 250 notes, which underwent bacteriological analysis, were found to be contaminated with bacteria. Parasites that were isolated from the notes included Ascaris lumbricoides (8.0 percent), Enterobius vermicularis (6.8 percent), Trichuris trichiura (2.8 percent), and Taenia species (4.0 percent). Bacteria that were isolated were Streptococcus species (21.6 percent), Staphylococcus species (12.8 percent), Escherichia coli (13.2 percent), and Bacillus species (5.6 percent). Among dirty/mutilated currency notes, parasite contamination and bacterial contamination were both significantly (p < .05) more pervasive (30.6 percent and 73.8 percent, respectively) than they were among clean and mint currency notes. Lower-denomination notes were more likely to be contaminated than were higher-denomination notes, although the difference was not statistically significant (p > .05). Parasite contamination and bacteria contamination were both most frequent in notes obtained from butchers and beggars. These results suggest that currency notes may be contaminated, especially with bacteria and enteric parasites, and may serve as sources of infection. Personal hygiene to reduce risk of infection is recommended.

Introduction: Front-line health workers in remote health facilities are the first contact of the formal health sector and are confronted with life-saving decisions. Health information systems (HIS) support the collection and use of health related data. However, HIS focus on reporting and are unfit to support decisions. Since data tools are paper-based in most primary healthcare settings, we have produced an innovative Paper-based Health Information System in Comprehensive Care (PHISICC) using a human-centred design approach. We are carrying out a cluster randomised controlled trial in three African countries to assess the effects of PHISICC compared with the current systems., Methods and Analysis: Study areas are in rural zones of Côte d'Ivoire, Mozambique and Nigeria. Seventy health facilities in each country have been randomly allocated to using PHISICC tools or to continuing to use the regular HIS tools. We have randomly selected households in the catchment areas of each health facility to collect outcomes' data (household surveys have been carried out in two of the three countries and the end-line data collection is planned for mid-2021). Primary outcomes include data quality and use, coverage of health services and health workers satisfaction; secondary outcomes are additional data quality and use parameters, childhood mortality and additional health workers and clients experience with the system. Just prior to the implementation of the trial, we had to relocate the study site in Mozambique due to unforeseen logistical issues. The effects of the intervention will be estimated using regression models and accounting for clustering using random effects., Ethics and Dissemination: Ethics committees in Côte d'Ivoire, Mozambique and Nigeria approved the trials. We plan to disseminate our findings, data and research materials among researchers and policy-makers. We aim at having our findings included in systematic reviews on health systems interventions and future guidance development on HIS., Trial Registration Number: PACTR201904664660639; Pre-results., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

With the increase in demand for wood and wood products, there is need to find alternative sources for the production of pulp and paper. Non wood plants have attracted interest due to their short growth cycles, moderate irrigation and fertilizer requirements and low lignin content. This study aimed at investigating the fibre characteristics of Agave sisalana for pulp and paper production. Leaves were collected from three sisal plant stands in Oyo State, Nigeria. The plant whorl was divided systematically into bottom, middle and top from which five leaves were randomly collected from each whorl position. The fibres of the leaves were extracted from which 2cm of fibres were taken from three positions on the leaf (top, middle and base). Extracted fibres were macerated and 3375 fibres were measured. The result shows that the fibre length of sisal increased with increasing length of the leaves from base to top with a mean value of 1.68mm. The fibre diameter and cell wall thickness averaged 16.98µm and 2.32µm respectively decreasing from the stem base to the top. The slenderness ratio averaged 99.4 while the coefficient of flexibility averaged 72.61. The highest value of the runkel ratio of Agave sisalana was 0.42. The fibres from sisal (Agave sisalana) leaves possess good fibre dimensions and derived values which will make it suitable for the production of high quality paper. [ABSTRACT FROM AUTHOR]

The article discusses importance of maintenance of archival paper materials for the academic institutions where they are located and for posterity in Nigeria. It mentions archival maintenance practices for paper based archival materials has been under researched in era of global access to information online; and also mentions archival maintenance practices requires controlling of environment to elongate archival paper based materials.

Evolution is one recurrent phenomenon that affects almost every facet of human endeavour. Libraries have had their own share in many ways. The green library concept, although, a relatively new-sprung initiative, have not been given full attention. The understanding of librarians, and the levels of adoption of the green library concept in Nigeria is reported herein. The descriptive survey approach was used. Results showed that librarians have the right perception about the concept, and have implemented or currently translating their policies, practices, and services in compliance with environmental sustainability objectives. However, much more needs to be done as the libraries also have not sufficiently engaged in climate change sensitization activities with patrons or their immediate community. The libraries do not collect rain water, recycle paper or reduce the use of plastics as stipulated. In implementing the initiative, low awareness, poor funding, lack of collaboration with environmental agencies among others have bedeviled their efforts. The establishment of a Nigerian Green Building Council (NGBC) for building standardisation with the support of the Nigerian Library Association is thus recommended for on-thespot redesigning of already built antique libraries. It is also pertinent to begin inspiring green architectural projects especially for newly proposed library buildings. [ABSTRACT FROM AUTHOR]

Purpose: In the past, the construction sector faced a low technological development level. Recently, studies have shown that the fourth industrial revolution (4IR) technologies play a significant role in construction project performance. But how prepared are the developing countries' construction consultants, a focus in Nigeria, in embracing the 4IR technologies in construction administration is yet to receive in-depth research. Thus, this paper aims to examine how Nigerian construction consultants are prepared to embrace 4IR technologies in pre- and post-construction activities. Design/methodology/approach: To evaluate the perceptions of construction consultants, the study conducted a virtual interview. The participants were asked the following key questions: What technologies that are currently linked with the 4IR and used by construction consultants in the industry? What factors may hinder the strategic application of 4IR by the construction consultants? What initiatives may be necessary to overcome the perceived encumbrances faced by the construction consultants? Twelve semi-structured interviews from selected construction consultants were engaged and collated data analysed via a thematic approach. Findings: The paper identifies digital software used by construction consultants that have a link with 4IR technologies. From the ten emerged hindrances, cost of adopting the technologies, unwillingness on the part of stakeholders to adopt, inadequate standards and reference architectures and absence of awareness were ranked high as the factors hindering construction consultants from using 4IR technologies. Initiatives that can overcome the perceived encumbrances are examined in detail. Research limitations/implications: This study is restricted to construction consultants in Nigeria, and only 12 participants were engaged, but these do not affect the strength of the results. Thus, this study recommends a mixed-methods approach for future research with broader coverage. Practical implications: The Government should intervene via subsidy regime and overhaul the academic curriculum to reflect the current trend of practices regarding technologies. Also, there should be vigorous enlightenment and pragmatic sensitisation of construction stakeholders and knowledge training of practitioners, among others, were suggested. As part of this paper's implications, a perception-based model was developed to promote 4IR technologies for construction consultants in the Nigerian construction sector. This model encourages the construction consultants to embrace 4IR technologies for better service delivery, project performance and client satisfaction. Originality/value: This paper appraised 4IR technologies' role in the construction sector, focusing on the preparedness of the construction consultants in Nigeria. Also, the study identified the issues and proffer initiatives to improve 4IR usage by construction consultants. [ABSTRACT FROM AUTHOR]

Bisphenol A (BPA) is a high production volume chemical that has wide industrial applications, especially as a color developer in thermal papers. The present study focused on the determination of levels of BPA in thermal receipts collected from different locations in Akure, Nigeria, and the estimation of daily intake of BPA through dermal absorption. Thermal receipts were collected from different locations, and the levels of extracted BPA were determined using fluorescence spectroscopy. The daily intake of BPA was estimated, and the amount was compared with the reference value. BPA was detected in all the samples analyzed with levels ranging from 1.50 to 3.16 mg/g. These values were lower than the values detected in thermal receipts obtained from other countries. The estimated mean daily intakes of BPA by dermal absorption due to handling of thermal receipts were 0.20 and 9.89 μg/day for the general population and the occupationally exposed individuals, respectively, and were much lower than the reference value of 50 μg/kg bw/day provided by the European Food Safety Authority. This indicates that dermal exposure to BPA is not a serious health risk to the population.

Introduction: There are lapses in Nigeria's data ecosystems with the consequences of imprecise and inaccurate data on humanitarian crises limiting accurate interventions. Therefore, we examined the data targeting processes in the humanitarian sector of Northeast Nigeria and the ethical concerns that arise when such data is collected and used to advance understanding and improve humanitarian protection systems. Methods: The fieldwork was done in two phases in Maiduguri Borno, North-East Nigeria, between 2021 and 2022. This period was selected because it was the climax of IDP camps in the Northeastern part of the country. Maiduguri was selected for the study because it is the capital of Borno state which is the epicenter of insurgency and internal displacements in Nigeria. Hence, a lot of the most vibrant IDP camps in Nigeria were in Maiduguri for care and security reasons. Fifty in-depth interviews were conducted among the displaced persons across five camps. We also interviewed twenty stakeholders and practitioners working with IDPs to understand Nigeria's data-based humanitarian contexts of internal displacement. The interviews were tape-recorded and transcribed verbatim by a language expert. The data were coded, and content analyzed to provide context and explore significant operational and ethical issues in data-driven humanitarian protection. Results: There are discrepancies in the definition of vulnerability in data gathering, putting into question how targeting is carried out to identify vulnerable people and its implications for exclusion. Different data banks and reliability issues across institutions and actors make room for a multiplicity of data and problematic synergy relative to data and ethics. Inconsistent ethical systems guide data gathering and utilization in IDP camps; for instance, there are ineffective norms of recording and securing informed consent during data gathering. States, partners, and IDP camps confront debilitating capacity gaps and equipment deficits that make updated data gathering, storing, retrieval, and utilization. Paper and digital data storage processes were often used with restricted access to only a few key stakeholders. There is vast data expropriation without standard recourse to justice and beneficence as ethical procedures in the humanitarian data space of northeastern Nigeria as a microcosm of Sub-Saharan African realities. Conclusion: There are enormous implications for effective and efficient targeting processes and outcomes, strategic inclusion, and ethical practices in conflict management, humanitarian interventions, and internal displacement in sub-Saharan Africa.
