Research Findings

The study analyzed the spatial variability of atmospheric visibility and meteorological parameters over selected cities in Nigeria. This study employed the use of secondary data which includes a 36 years (1982-2017) visibility, rainfall, relative humidity, windspeed and temperature data which was gotten from the weather register of the selected meteorological stations. Descriptive statistics, analysis of variance (ANOVA) and student t-test were employed in the analysis of data. Research findings revealed that revealed that the coastal cities witnessed better visibility than the northern part of the study area especially during the dry season. The Analysis of Variance (ANOVA) revealed statistically significant variation in visibility, temperature, rainfall, relative humidity and windspeed at 95% probability level across the selected locations. The student t-test statistics also revealed that a statistically significant difference in visibility, rainfall, windspeed and relative humidity occurs between the wet and dry seasons in most of the selected cities. The study recommends that awareness campaigns and enlightenment programmes be undertaken by various meteorological authorities and other relevant government agencies to improve the awareness of members of the public on the need to adhere strictly to weather alerts and warning systems.

Goal of this paper was to determine differences between deaf and hard of hearing (DHH) students in motivation for academic achievement and compared to hearing students. Sample was comprised of 94 students averaging 16.5 ± 1.34 years of age. Sample was divided into three groups (deaf, hard of hearing and hearing students). For examination, we used the following: Great Inventory of Achievement Motivation, measuring instrument for assessing students’ motivation for academic achievement, that is comprised of five subtests i.e. 13 areas of measurement (Suzic, 2006). For difference testing t-test was used along with analysis of variance (ANOVA). T-test determined statistically significant difference in areas of “self-efficacy “, “engagement”, “control” and “non-conformism”. Deaf and hard of hearing students displayed less motivation on these parameters than their hearing counterparts. In the area of “valuing academic achievements” DHH students together displayed, better motivation than their hearing counterparts and difference was statistically significant. With Analysis of Variance i.e. with additional Tukey test, we have determined that statistically significant difference is present only when comparing deaf and hearing students, but not when comparing hard of hearing and hearing students.

The purpose of this chapter is to assess the contribution of the banking sector’s recapitalization to economic growth. Secondary data of all banks in Nigeria for 1980-2006 from Central Bank of Nigeria were used for the study. The findings of the study revealed higher mean GDP (N86.229 trillion) at post-recapitalization era compared to pre-recapitalization era (N56.860 trillion). Furthermore, 37% and 25% growth in GDP were recorded at post- and pre-recapitalization era, respectively. Selected indicators (bank credit, asset, saving deposit, and total loan) were all higher in the post recapitalization era. The result of t-test showed that there was a significant difference in GDP at pre and post recapitalization era at 5% significance level holding inflation constant. Bank asset had significant effect on GDP in the post-recapitalization era. Bank performance indicators could not fully account for growth and development in Nigeria’s economy though growth was recorded. Under subsequent initiatives, bank asset and total loan increased massively, while bank credit and saving deposits were stepped up via credit and savings incentives provisions for greater impact on growth in Nigeria.

ABSTRACT Objective: The purpose of this study was to determine the perception of smile esthetics among orthodontists and laypersons with respect to unilateral maxillary canine torque variations in a frontal smile analysis. Methods: Full face and close-up smile photographs of two subjects (1 man and 1 woman) were used. Both smiles displayed healthy maxillary anterior dentitions. The images were digitally altered to obtain a bilateral 0° torque in the maxillary canines. From this image, unilateral variations of the left canine were made with -15°, -10°, -5°, 0°, +5°, +10° and +15°. Final images were randomly assembled into an album that was given to 53 orthodontists and 53 laypersons. Each rater was asked to evaluate the attractiveness of the images using visual analog scales. Data collected were statistically analyzed with one-way analysis of variance with Tukey post-hoc test and the unpaired Student t test. Results: For orthodontists, most attractive smiles were those with 0°, -5° and -10°. For laypersons, most attractive smiles were those with 0°, -5°, -10°, -15° and + 5°. For both groups, the lowest scores were given for the smiles with +10° and +15° torque. When comparing the perceptions of the orthodontists and laypersons, they did not show statistical differences in most situations. Moreover, in general, there was no significant difference between the full-face and close-up assessments of the smiles. Conclusions: The present findings indicated that smiles with unilateral palatal (negative values) maxillary canine torque variations were more tolerated than smiles with buccal crown torque (positive values) variations.

More than ever, the concept of Internal Control System has become a crucial concern for todays entities, requiring their respective board of directors and/or executive managers to hold-on the candle-light of high integrity, zero tolerance to frauds and embezzlement of public funds, compliance with different sort of internal and external environments rules and regulations, as a prerequisite to competitive edges. With this regard, the present study examines whether there is or not a significant difference between respondents perceptions on internal control practices in some selected government business enterprises in Rwanda. Primary and secondary data have been used for this study, where the first ones have been collected through observation, non-structured interview and questionnaires with 0.814 Cronbachs Alpha reliably test. Descriptive statistics in terms of frequencies and percentages were used to assess the level of respondents perceptions, and T-test was used to find out if there was any significant difference between variables. The study found that there is no significant difference existing with respect to control environment, risk assessment, control activities, information and communication, but when it came to monitoring activities, a significant difference has been evident. All in all, the overall administered t-test concluded that there is a significant difference between respondents perceptions on internal control practices with regard to Rwanda government business enterprises. Basing on findings, some areas needing improvement like staff professional trainings, system of information gathering on frauds and embezzlements trends have been recommended to companies under study.

Purpose: To compare the effect of two learning opportunities, clinician feedback and video self-assessment, on 5th-year chiropractic students' patient communication skills, specifically those required for history taking. Methods: A cohort of 51 final-year students was divided into two groups. The first group received immediate feedback from a clinical supervisor following a history-taking encounter with a patient. The second group performed self-assessments of their videotaped history-taking encounter. An end-of-year Viva Voce examination was used to measure the effectiveness of the students' history-taking skills, using two subscores, one for behavior and another for content, as well as an overall total score. An unpaired t-test was performed to determine whether any significant difference occurred between the two groups of students. Each group was then subdivided into two subgroups based on gender, and a two-way analysis of variance was performed to determine whether the type of feedback or the students' gender had any significant effect on the outcome of the Viva Voce. Results: There were no significant differences between the two groups of students in terms of their final scores in the Viva Voce. After dividing each group into their gender subgroups and further analysis of the results, neither the mode of feedback nor the students' gender had any significant effect on the outcome of the Viva Voce. Conclusion: This study suggests that, for a mixed cohort, video self-assessment and clinician feedback are equivalent in their ability to enhance students' communication skills relating to history taking.
