ABSTRACT

This work is about seasonal autoregressive integrated moving average (SARIMA) modeling of monthly rainfall of Rivers State of Nigeria from 1981 to 2016. The time plot shows seasonality of period 12 months as typical of rainfall data. Even though the Augmented Dickey Fuller test of unit root ceritifies the series as stationary the correlogram shows an undulating sinusoidal pattern of seasonality of period 12, as expected. The correlogram shows positive spikes at lag 12 and comparable spikes at the autocorrelation function (ACF) at lags 11 and 13 and spikes at lags 12 and 24 on the partial autocorrelation function (PACF). This suggests the involvement of a seasonal autoregressive order of 1 or 2 and a moving average non-seasonal order of 1 and a seasonal order of 1. This means the involvement of a SARIMA(0,0,1)x(1,1,1)12 model. Other models worth testing are SARIMA(0,0,1)x(2,1,1)12 model and a SARIMA(1,0,1)x(0,1,1)12 model. By AIC and R2 the lattest model was chosen. The correlogram of the residuals showed no significant spike, an evidence of model adequacy. The forecasts of 2017 were obtained finally.

ABSTRACT

This paper centered on Alternative Dispute Resolution (ADR) in the Nigeria work organizations- a situation analysis. The study employed a theoretical –based approach and a conceptual review of related literatures. Three objectives were formulated to guide this study. The study revealed that ADR has a significant influence on organizational and employees’ performance in the Nigeria work organizations. The study also revealed that the different methods of ADR such as arbitration, mediation, negotiation, collaboration, compromise, good governance, communication, facilitation, expert determination, mini-trial, etc. if adopted appropriately would have a significant effects on operational efficiency and effectiveness of work organizations in Nigeria.

ABSTRACT: This paper examines the views and ethical justifications for tax evasion in Nigeria. The survey method was employed for the study which involves the administration of questionnaires to sixty respondents made up of the academia, civil servants, businessmen and students. The questionnaire contains scale depicting the basic views on tax evasion. Most of the statements begin with the phrase “tax evasion is not unethical if …” which allows the respondents to either agree or disagree with the statement. The responses to each question were tallied and ranked to determine the circumstances whereby tax evasion might be considered most or least ethical. The pooled t-statistic was used to test whether there were significant differences among the respondents on the view on tax evasion. It was discovered that the respondents especially the academia agree that tax evasion was ethical. Similarly, the academia was eighteen structured statements in a 5-point likert less opposed to tax evasion than the other respondents. Moreover, the female respondents (academic and other respondents) expressed more support for tax evasion than their male counter parts. Among the most important justifications or reasons for tax evasion were: religious, political and ethnic discrimination, perception of injustice in government allocation of projects. Unfairness in the tax system was the least justification for tax evasion. It is concluded that there is serious ignorance of tax laws on the part of the respondents as no reason is sufficient to justify tax evasion which is a criminal offence. Therefore, it is recommended that government and the tax authorities should engage in massive awareness campaigns and tax education to enlighten the public on the need to pay taxes instead of evading it and also to correct the wrong perception of tax obligations of citizen in   Nigeria.

ABSTRACT

The personnel or workforce of an organization are the key to efficient service delivery and without an adequate, skilled and well-motivated workforce operating within a sound personnel management system, the realization of organizational objectives is far-fetched, thus, as a student of public personnel management, an administrator or a manager that underrates the crucial role and underplays the importance of people in goal achievement (whether public or private sector) can neither be effective nor efficient. The recognition of the role and importance of public personnel management in the workplace has led to a demand for graduates who are trained and qualified in public personnel management who can advise organizations in this area, and the highest development of a career structure through which such an employees may rise to the highest levels of the organization.

ABSTRACT

Alcohol is a known central nervous system (CNS) depressant, having properties in common with general anesthetic agents, appearing to depress the midbrain reticular activating system. This experimental study ascertained the effect of alcohol (Brandy) on amplitude of accommodation (AA) of undergraduate students of Madonna University, Elele, Rivers state, Nigeria. A total of 53 young adults between the ages of 18 – 29 years with a mean age of 22.13 ± 2.49 years were involved in this study out of which 30 (56.60%) were males with mean age of 22.27 ± 2.92 years and 23 (43.40%) were females with mean age of 21.96 ± 1.82 years. The AA was measured before the ingestion of 40ml of alcoholic beverage after which same measurement was repeated three times consecutively after 15, 30 and 45 minutes respectively. Data collected were analyzed using statistical package for social science (SPSS version 25). The Friedman’s test was used to test for significance on the effect of alcohol on AA across the various periods of measurements. Gender influence on the effect of alcohol on AA was analyzed using Kruskal-Wallis test. Statistical significance was considered at p-value ≤ 0.05 (level of significance). The findings showed a slight reduction in mean AA after 15mins (10.81± 2.19), 30minutes (9.51 ± 2.18) and 45 minutes (8.74 ± 2.27) when compared to the mean baseline (12.60± 2.51) for the right eye (OD). There was also a slight reduction of mean AA after 15minutes (10.75± 1.76), 30minutes (9.66 ± 1.76) and 45 minutes (8.91 ± 1.99), when compared to the mean baseline (12.49± 2.13) for the left eye (OS). There was no statistically significant association between gender and the effect of alcohol on AA. The study concluded that concentrated  alcoholic beverages are capable of causing a slight decrease in AA lasting over 45 minutes and recommended that alcohol intake should be avoided at least 60 minutes prior to engaging in visually tasking activities especially among individuals with accommodative or convergence anomalies.

Key words: Alcohol, accommodation, convergence, visual task.

ABSTRACT

Military medical personnel deployed, experience a high level of stress in meeting the health needs of the entire personnel in military operations. This can lead to burnout which in turn threatens patient care. This study, therefore, aims to investigate factors that predicted burnout in these healthcare professionals deployed in Northeast Nigeria fighting the insurgency. A total of 120 participants were purposively selected to take part in the study. Two sets of instruments; the personal functioning inventory (PFI) to measure coping styles and the Maslach Burnout Inventory (MBI) as a measure for burnout while sociodemographic information obtained included rank, age, marital status, religion years in service professional discipline and years of professional experience. Descriptive statistics were used to present sociodemographic factors of participants while chi-square and one-way ANOVA was used to obtain the individual and joint influences of sociodemographic variables and coping on burnout respectively.  Results obtained revealed that sociodemographic variables and coping styles would significantly independently and jointly predict burnout among Nigerian military medical personnel. It was suggested that Military commanders should adopt supportive approaches and different strategies to reduce the incidence of burnout among their medical personnel to achieve effective patient care for operational effectiveness. These findings were discussed based on the literature reviewed while recommendations were made accordingly.

ABSTRACT

Strabismus is the most common amblyopic factor. However, few studies have been done to determine the prevalence of strabismus in Ogun State. This study was aimed to determine the prevalence of Strabismus among Secondary School students in Ogun State. This was a cross-sectional study. With all ethical considerations sustained, three hundred and sixty (360) students who were within the age range of 9 to 22 years were randomly selected from three (3) public secondary schools selected from each of the three senatorial districts of Ogun State. Participants involved in the study were 168 males (46.3%) and 192 females (53.7%). Tests were conducted during the normal academic session for a period of Nine (9) months using instruments such as Snellen Visual Acuity Chart, Occluder, Pen Torch, Prism Bars, and a sheet to record the data. Simple case history and questionnaire were used to determine demographics, and information about the history of trauma, birth history of squint, family history of squint, and to rule out other pathological anomalies from the participants. Snellen’s Visual Acuity Chart, Cover and Uncover tests, Hirshberg Test, and Krimsky test, was also conducted to diagnose and determine the prevalence and pattern of strabismus in the population. Data obtained was analyzed was using Statistical Package for Social Sciences (SPSS) version 16, and tested with descriptive statistics frequency and chi-square, while a p-value was set at 0.05 (p<0.05). The prevalence of strabismus was 1.90%, and this was significantly high compared to most regions in Africa. Esotropia was more common than Exotropia in equal distribution. Early detection and treatment, as well as training for non-ophthalmic staff like teachers to detect and refer cases of strabismus are advocated.
