The Relationship Between Emotion Intelligence and Examination Anxiety Behaviour Among Students in Public Senior Secondary School in Delta State

This study examined the relationship between emotional intelligence, and examination anxiety behaviour among students in public senior secondary school II (SS2) in Delta State. Two research questions and two hypotheses guided the study. Related literature was reviewed. The study adopted an ex post facto research design and correlation method. The population of the study was 40522 comprised of students in public senior secondary school II in Delta State. A sample of 1,070 students was used. A questionnaire was the instrument for data collection. The questionnaire was validated through expert judgment and factor analysis. The instrument had a Cronbach alpha reliability index of 0.73 for the metacognitive awareness scale, 0.65 for the emotional intelligence scale, and 0.71 for the examination anxiety behavior scale. Researchers administered the questionnaire to the sampled students. Pearson Product Moment Correlation and Coefficient Determination were used to answer the research questions while regression statistics and extension by Andrew Hays were used to test the hypotheses at 0.05 level of significance. The findings showed that: there was a significant relationship between emotional intelligence and examination anxiety behaviour, and there was a mediating impact of metacognition in the relationship between emotional intelligence and examination anxiety behaviour. This study concludes that metacognition is a mediator between emotional intelligence and examination anxiety behavior.  Recommendations were that a School counsellor/psychologist should be employed to help students develop positive emotions and recommendations were made among others that school Counsellors/Psychologists should be employed to help students develop positive emotions.

Overview of Remaining Useful Life prediction techniques in Through-life Engineering Services

Through-life Engineering Services (TES) are essential in the manufacture and servicing of complex engineering products. TES improves support services by providing prognosis of run-to-failure and time-to-failure on-demand data for better decision making. The concept of Remaining Useful Life (RUL) is utilised to predict life-span of components (of a service system) with the purpose of minimising catastrophic failure events in both manufacturing and service sectors. The purpose of this paper is to identify failure mechanisms and emphasise the failure events prediction approaches that can effectively reduce uncertainties. It will demonstrate the classification of techniques used in RUL prediction for optimisation of products’ future use based on current products in-service with regards to predictability, availability and reliability. It presents a mapping of degradation mechanisms against techniques for knowledge acquisition with the objective of presenting to designers and manufacturers ways to improve the life-span of components

RELIGIOUS BELIEFS, PARENTING STYLES AND PEER PRESSURE AS CORRELATES OF GET-RICH-QUICK SYNDROME AMONG UNDERGRADUATES OF UNIVERSITIES IN DELTA STATE, NIGERIA

This study investigated the relationship among religious beliefs, peer pressure and the get-rich-quick syndrome among Delta State University undergraduates. The study was guided by five research questions and five hypotheses. The study used the correlational method of ex-post facto research design. The target population of this study comprised the entire undergraduates of universities in Delta State in the 2020/2021 academic session, with a total population of 25,575 undergraduates. A sample size of 384 undergraduates constituted the samples for the study, through proportionate and stratified sampling techniques. The instrument for this study was a questionnaire. The questionnaire was validated by experts’ judgement and factor analysis with a Cronbach alpha reliability coefficient of 0.87 for Religious Belief Rating Scale; 0.88 for Authoritative Parenting Style; 0.70 for Authoritarian Parenting Style; 0.79 for Permissive Parenting Style; 0.93 for Uninvolving Parenting Style; 0.78 for Peer Pressure Rating Scale; and 0.90 for Get-Rich-Quick Syndrome Rating Scale. The research questions were answered with the aid of Pearson’s correlation coefficient of determination. The hypotheses were tested using regression statistics at a 0.05 level of significance. The findings of the study revealed that there is a significant relationship between religious beliefs and get-rich-quick syndrome among undergraduates of universities in Delta State; there is a significant relationship between parenting styles and get-rich-quick syndrome among undergraduates of universities in Delta State; that there is a significant relationship between peer pressure and get-rich-quick syndrome among undergraduates of universities in Delta State; that there is a significant relationship among religious beliefs, parenting styles, peer pressure and get-rich-quick syndrome among undergraduates of universities in Delta State; and that there is no significant moderating impact of sex on the relationship among religious beliefs, parenting styles, peer pressure and get-rich-quick syndrome among undergraduates of universities in Delta State. The study recommended that parents should improve on their relationship with their adolescents and choose the right parenting style that will help the adolescents to abstain from indulgence in get-rich-quick syndrome.  Article visualizations

Development of an ontology for aerospace engine components degradation in service

This paper presents the development of an ontology for component service degradation. In this paper, degradation mechanisms in gas turbine metallic components are used for a case study to explain how a taxonomy within an ontology can be validated. The validation method used in this paper uses an iterative process and sanity checks. Data extracted from on-demand textual information are filtered and grouped into classes of degradation mechanisms. Various concepts are systematically and hierarchically arranged for use in the service maintenance ontology. The allocation of the mechanisms to the AS-IS ontology presents a robust data collection hub. Data integrity is guaranteed when the TO-BE ontology is introduced to analyse processes relative to various failure events. The initial evaluation reveals improvement in the performance of the TO-BE domain ontology based on iterations and updates with recognised mechanisms. The information extracted and collected is required to improve service k nowledge and performance feedback which are important for service engineers. Existing research areas such as natural language processing, knowledge management, and information extraction were also examined

Service Knowledge Capture and Reuse

The keynote will start with the need for service knowledge capture and reuse for industrial product-service systems. A novel approach to capture the service damage knowledge about individual component will be presented with experimental results. The technique uses active thermography and image processing approaches for the assessment. The paper will also give an overview of other non-destructive inspection techniques for service damage assessment. A robotic system will be described to automate the damage image capture. The keynote will then propose ways to reuse the knowledge to predict remaining life of the component and feedback to design and manufacturing

The reinforcing potentials of Velvet tamarind seed shell as filler in natural rubber compounds

This work focused on the development of a reinforcing filler from renewable natural plant resources as part of the ongoing search for environmental friendly fillers that will substitute synthetic reinforcing fillers such as carbon black and silica in rubber manufacturing. The cure characteristics, physico-mechanical and equilibrium swelling properties of natural rubber, Standard Nigerian Rubber (SNR10) vulcanizates separately filled with commercial grade carbon black (CB), N330 and pulverized natural plant material, Velvet tamarind (VT), seed shell were investigated. The results of the analyses showed that the scorch and cure times decreased while the maximum torques increased with increasing filler loading for both filled-SNR10 vulcanizates. The tensile strengths of both VT-filled and CB (N330) filled-SNR10 vulcanizates increased to 30 phr and 40 phr respectively and decreased with increasing filler loading. The modulus at 100% strain, specific gravity, abrasion resistance and hardness increased while elongation at break, equilibrium swelling and rebound resilience decreased with increasing filler loading for both filled-SNR10 vulcanizates. The results showed that Velvet tamarind seed shell manifested a reinforcing effect on the SNR10 compounds but lower than that of CB (N330) filler.Keywords: Natural rubber, fillers, reinforcement and vulcanizate properties

Calamus deerratus fibre reinforced natural rubber vulcanizates

This research study investigates the potentials of Calamus deerratus fibre (CDF) as a reinforcing filler in natural rubber, Standard Nigerian Rubber (SNR10)   vulcanizates. The Calamus deerratus was cut, dried, pulverized, characterized and incorporated into the natural rubber compounds and the effects on the cure  characteristics and physico-mechanical properties of the CDF-reinforced natural rubber vulcanizates were determined. The results of the analyses, in comparison with a standard carbon black, CB(N330)-filled vulcanizates showed that the CDF manifested a reinforcing effect on the SNR10 vulcanizates but inferior to carbon black, N330-filled vulcanizates. The maximum torque, abrasion resistance, modulus, specific gravity and hardness increased while the scorch time, cure time,   elongation at break and rebound resilience decreased with increasing filler content. The cure time and scorch time were however higher in CDF-filled SNR10   vulcanizates compared to those filled with carbon black, N330. Tensile strengths of CB(N330)- and CDF- filled vulcanizates increased to optimum levels at 40 phr  and 30 phr respectively and decreased with increasing filler content. The results however showed that CDF imparted lower reinforcing potential as shown by the   lower tensile strength, abrasion resistance and modulus. The hardness results of the CDF-filled vulcanizates showed slight superiority over that of CB(N330)-filled vulcanizates.Keywords: Natural rubber, Calamus deerratus, fillers, reinforcement and vulcanizates

Leasing as an Alternative Source of Finance: The Nigerian Experience

The Nigerian economy is at present beset with multi-dimensional socio-political-economic problems. Globalization, deregulation, and the instability of the value of the naira have crippling effects on business organizations. Fiscal and monetary policies put in place to nurse the economy back to buoyancy have tended to squeeze and curtail credit expansion. This paper advocates that leasing is an alternative of finance that could be used to assist companies in particular and the Nigerian economy in general to the path of economic growth and development

Developing and Validating a Type 2 Diabetic Patient Drug Telephone Reminder Program

Research has shown that telephone drug reminder scripts can be an effective way to increase drug adherence and decrease health care costs for persons with Type 2 diabetes. The purpose of this project was to develop and validate a telephone drug reminder script for Type 2 diabetes patients based on evidence-based practice. Following a review of the literature, a telephone drug reminder script was developed for Type 2 diabetic patients to educate and improve drug adherence. Five local experts with at least 10 years\u27 experience in diabetes treatment, education, and or research were asked to participate in the validation of the developed telephone drug reminder script. The 5 experts were placed in a quiet room and asked to review the developed telephone drug reminder script and complete an 18-question Likert-type survey on the design of the script, the content, and the process and time for completion. Each expert was given ample time to review and provide feedback on the developed telephone script. Descriptive analysis was used to analyze survey results. All local experts strongly agreed that the design was easy to follow and understand and that there was enough content to help improve Type 2 diabetic patient drug education and adherence. By improving drug education and adherence, 95% of the experts agreed that there would be a decrease in outpatient clinic visits for diabetic management. Revisions to the telephone drug reminder script were made based on the survey analysis. The validated telephone script will be used in a pilot study compared with standard of care in the future. The validated evidence-based telephone drug reminder script for Type 2 diabetic patients has the potential to improve patient outcomes and reduce health care costs for those living with Type 2 diabetes

Biochemical effects of ethylene diamine tetra-acetic acid (EDTA) on cadmium treated maize (Zea mays L.) and cowpea (Vigna unguiculata L.)

The effects of ethylenediaminetetra-acetic acid (EDTA) on germination, length of stem, area of leaf, fresh weight, level of lipid per oxidation, alkaline phosphatase, acid phosphatase, super oxide dismutase (SOD) and catalase in the roots of cadmium (Cd) treated maize (Zea mays L) and cowpea (Vigna unguiculata L) seedlings after 7 and 21 days of germination were determined in this study. The results obtained, indicate that at the end of 7 and 21 days of exposure to Cd, percentage germination of the seeds were not significantly different in both control and test soil (p>0.05). Morphological parameters (area of leaf, length of stem and fresh weight) were significantly reduced by Cd after 7 and 21 days. The supplementation of the soil sample with EDTA (0.5 mM or 1.0 mM) reversed the effect of Cd on these parameters as it significantly increased length of stems, area of leaf and plant fresh weight. There was a significant decrease in root acid phosphatase, root alkaline phosphatase, super-oxide dismutase (SOD) and catalase activity in both plant species. Both used doses of EDTA to ameliorate the above biochemical parameters. Increased level of root lipid peroxidation in Cd treated maize and cowpea seedlings was observed after 7 and 21 days of germination. Albeit, the level of lipid peroxidation in the root of Cd treated maize was significantly higher than that of cowpea, an indication that cowpea may be more tolerant than maize to Cd toxicity. The treatment of plant with, concentrations of EDTA (0.5 and 1.0 mM) failed to decrease the Cd induced, but increased the level of root lipid peroxidation. These results indicate that EDTA (0.5 mM and 1.0 mM) could be used for the treatment of Cd toxicity in plants; although, EDTA did not totally protect cowpea seedling from oxidative stress.Key words: Heavy metal, phytoremediation
