Survey datasets on the externalizing behaviors of primary school pupils and secondary school students in some selected schools in Ogun State,Nigeria
This data article contains the partial analysis (descriptive statistics)of data obtained from 1770 primary school pupils and secondary school students in three Local Government Areas of Ogun State,Nigeria. The school sareei the privately owned or public(government owned)schools.The aim of the field survey is to measure the level and patterns of externalizing behavior of the respondents.The data was collected using a standardized questionnaire.The questionnaire is a modification of Achenbach manual for Child behavior checklist(Achenbach,2001)[1]and manual for Youth self-report (AchenbachandRescorla,2001)[2]. The questionnaire was designed to suit the demographic and socio-cultural nature of the target population Analysis of the data can provide useful insights to the patterns of externalizing behavior of primary school pupils and secondary school students
Dataset on statistical analysis of editorial board composition of Hindawi journals indexed in Emerging sources citation index
This data article contains the statistical analysis of the total, per-centage and distribution of editorial board composition of 111 Hindawi journals indexed in Emerging Sources Citation Index(ESCI) across the continents. There liability of the data was shown using correlation,goodness-of-fit test,analysis of variance and
statistical variability test
Exploration of editorial board composition,Cites core and percentiles of Hindawi journals indexed in Scopus
The statistical analysis of editorial board composition, Cite score and percentile of 180 Hindawi journals currently indexed in Scopus are presented in this data article. The three indicators(editorial board composition, Cites core and percentile)can be helpful for researchers to make informed decision about the impact of Hindawi journals. The last two indicators are components of Scopus Cites core metric
Dataset and analysis of editorial board composition of 165 Hindawi journals indexed and abstracted in Pub Med based on affiliations
This article explores the editorial board composition (across the six continents) of Hindawi journals indexed in Pub Med. The data set used is the official affiliation of the board members available at the various web pages of Hindawi journal website and not the countries of origin of the editorial board members. Summary statistics
were presented and the raw data set was provided for further analysis by interested scholars. The percentage of the editorial board composition across the continents was presented,the data set of Hindawi journals indexed in both Hindawi and Scopus were also presented and measured in terms of Cite score and percentiles. The data set can be used in journal evaluation,auditing,bibliometric analysis,management of smart campus;ranking and
the analysis can be extended to other journal indexation
DIFFERENTIAL CALCULUS NOTES ON WRAPPED EXPONENTIAL DISTRIBUTION
Wrapped probability distributions are used in modeling circular data arising from physical, medical and social sciences. Wrapped exponential distribution is obtained from wrapping exponential distribution in a unit sphere. This work considers the generation of ordinary differential equations whose solutions are the probability functions of wrapped exponential distribution. This will help in understanding the nature of exponential distribution when wrapped in a circle. Different methods can be used in obtaining the solutions to the differential equations generated from the process. Some unique patterns were observed which can channel research activities towards the area. In conclusion, some expressions were obtained that link the probability functions with their respective derivatives
Hepatitis E Infection in Nigeria: A Systematic Review
BACKGROUND: Research done globally on hepatitis E virus (HEV) infection is far fewer compared with other types of hepatitis virus infection. Little is known on the prevalence of HEV in Nigeria.
AIM: The present study presents the prevalence of HEV infection in Nigeria from a few available research papers on HEV. The detailed statistical analysis was used to analyse the prevalence of HEV in humans and animals.
MATERIAL AND METHODS: A literature search in Web of Science, Scopus and PubMed databases was done, and a final 7 articles were selected. Minitab 17.0 was used to perform the correlational and binary logistic analyses.
RESULTS: Serum and faecal analysis of blood and stool samples of 1178 humans and 210 pigs (animals) were done, and the presence of anti-HEV IgG or HEV RNA in the study samples were 127 and 138 respectively. Further analysis showed the prevalence of HEV are 10.8% and 65.7% in humans and animals, respectively. Weak positive non-significant association (r = 0.327, p-value = 0.474) was obtained between the target (humans and animal) and the HEV infection (positive) groups. The application of binary logistic regression yielded an equation that can be used to predict the target group from the HEV positive humans or animals. Generally, the logistic model was not statistically significant (p-value = 0.376), and the model was able to explain 9.3% of the deviation or variability of the model. The odds ratio is OR = 1.0344 with 0.9550, 1.204 95% Confidence Interval (CI). Thus, in Nigeria, the odds of prevalence of HEV in animals are 1.0344 higher than humans.
CONCLUSION: The risk factors obtained from the few available articles are consistent with the global epidemiology of HEV infection. Food and animal handlers and those that consume unsafe water are the key people at risk of HEV infection in Nigeria
Systematic Review of Prevalence of Antepartum Depression during the Trimesters of Pregnancy
BACKGROUND: Depression is prevalent during antenatal and postnatal stages of pregnancy. The effect of depression can be seen in complications during and after pregnancy, fetal growth retardation, abortions and preterm births. The literature abounds on postpartum depression (PD) while few studies are on antepartum depression (AD).
AIM: The systematic review aims to compute the prevalence of AD from published articles.
MATERIAL AND METHODS: The published articles (26) used in this review were obtained from the search of the search keywords “Depressive conditions in pregnancy AND trimesters”. All the articles were considered irrespective of language and their citation status as of the time of the query. Only articles that presented the prevalence mean and sample size were included. Articles on questionnaires filled by nonpregnant women and men were excluded. Articles that presented the prevalence of depression for the postpartum period only were excluded but were included if they addressed depression at both postpartum and trimester(s) of pregnancy. P-value of less than or equal to 0.05 was considered significant.
RESULTS: Analysis of the 26 articles showed that 4,303 subjects tested positive for depression in a sample of 28,248 pregnant mothers, giving the prevalence rate as 15%. Confounding was removed, and the sample size was adjusted to be 25,771 and 4,223 were screened to have depressive symptoms, thereby giving a new prevalence rate as 16.4%. It was also revealed that AD is most prevalent in the last trimester of pregnancy and least in the second trimester. Pregnancy duration and PD are not correlated with AD. This implies that AD can be observed in any period of the pregnancy and cannot predict the incidence of PD.
CONCLUSION: Efforts must be intensified to monitor pregnant women during the third trimester to reduce the incidence of maternal depression during pregnancy, thereby reducing the prevalence
