The Moderating Role of Work Passion in the Relationship Between Organizational Climate and Burnout in a Sample of Secondary School Teachers
Get PDFThe study investigated the moderating role of work passion in organizational climate and burnout relations among secondary school teachers. A total of two hundred and one (201) participants comprising 28 male and 182 female secondary school teachers from the ages of 24 to 46 years (M = 32.54,SD = 4.03) were drawn for the study using two-stage sampling. Burnout Inventory (Maslach & Jackson, 1986), Organizational Climate Scale (Litwin & Stringer, 1968) and Work Passion (Vallerand, Houlfort & Bourdeau 2003) were used for data collection. A correlational design was adopted for this study , while a moderated hierarchical multiple regression was used for data analysis. Findings show that work passion negatively correlated with emotional exhaustion dimension of burnout of (r= -.12,p < .05), work passion negatively correlated with depersonalization dimension of burnout (r= -.23,p < .001), work passion did not correlate with feeling of reduced personal accomplishment. Organizational climate did not correlate with any dimension of burnout (emotional exhaustion, r= -.08, depersonalisation, r= -.09 and feeling of reduced personal accomplishment, r= .02 at p< .05). Work passion negatively moderated the relationship between organizational climate and two dimensions of burnout (emotional exhaustion, β= -.21 and depersonalisation, β= -.20 at p< .01). Thus, school management should motivate school teachers to enhance work passion, so as to contribute to a decrease in both emotional exhaustion and depersonalization

Implementation of Strategic Human Resource Management Policies and Labour Turnover in Nigeria organizations: A Study of Emenite Company Ltd, Enugu State
Get PDFIn this study, Implementation of Strategic Human Resource Management Policies and Labour Turnover in Nigeria Organisations: A Study of Emenite Company Limited, Emene, Enugu State, the researcher’s interest focused on finding the impact of some SHRM policies implementation on the rate of job turnover. Taro Yamene’s formula was used to draw the sample of approximately 116 respondents from the population of 168 employees in the study institution. The primary data were collected through the instrument of questionnaire and observation. The secondary data were sourced from textbooks, journals, magazines, newspapers, libraries and the internet. Likert Scale formula and z-test statistics were adopted in the data analyses and hypotheses testing. The result of the study reveals that the identified HR policies well implemented and vigorously practised results in extremely low rate of turnover in organisations as evident in the hypotheses tests. On the other hand, the reverse becomes the case (high rate of labour turnover) when those policies were poorly implemented as employees will leave the services of the company in droves. The study recommends as panacea to high rate of labour turnover that: (1) management of human resource in any organization should be a strategic issue; (2) organizations should embrace joint ownership programmes to provide employees opportunity for sense of belonging and retention; (3) organization should maintain a standard compensation or remuneration package above the industry standard to keep their employees; (4) organization should maintain a coherent appraisal systems for promotion, recognition and reward for high performing employees; and (5) maintain unbiased functioning grievance procedures for disciplinary measures and avoid preferential treatment and god-fatherism
Political Ideology and its Influence on Criminal Justice Policy in Nigeria
Get PDFThe creation and implementation of criminal justice policies are heavily influenced by political ideology, which can impact the fairness and equity of these policies. This study utilizes Rational Choice Theory, Game Theory, and Conflict Theory as analytical frameworks to explore how political ideology shapes policymakers\u27 preferences, beliefs, attitudes, and decision-making in the criminal justice system. The research highlights the importance of recognizing the role of political ideology in shaping criminal justice policies and underscores the need for evidence-based policies that prioritize the interests and well-being of all stakeholders. However, this study identifies biases and inequities in criminal justice policy resulting from political ideology and offers recommendations for addressing these issues, including involving community members in the policy-making process, promoting transparency, and increasing diversity in the criminal justice system. Policymakers are urged to consider the impact of political ideology on policy and work towards equitable and effective policies that promote public safety and justice for all
Public Order Act Enforcement in Nigeria’s Fourth Republic: An Assessment of State Governors’ Reckless Interference and Implication for Opposition Politics and Democratic Stability
Get PDFDespite the constitutionally strategic status of state as the second tier of government in Nigeria’s federal system and the seemingly imperial position occupied by state governors in the present political dispensation; these state governors who also major as chief executives and chief security officers of their various states have in recent times been known as mainstay of corruption in Nigeria especially in the fourth republic, operating what essentially could better be described as fiefdoms under their spheres of influence. Suffice to say that the governors have always tended to represent vested interests opposed to popular democratic rules and procedures. With respect to public order act and its enforcement therefore, it’s not in doubt that the act places the buck on the Nigerian police force. Nevertheless, state governors also have roles under the law to that effect as chief security officers of their various states. Confronted by prevailing reality, with respect to public order enforcement in Nigeria, this study explored the copious and arbitrary interference of state governors and implication for opposition politics and democratic stability in the fourth republic. Available secondary evidence revealed that most state governors are averse to opposition politics and have flagrantly used their position to frustrate, hoodwink, repress and stifle opposition political parties by using the police to deny them right to use public space for rallies and campaigns under the guise of enforcing public order. This indeed has massively contravened the fundamental right to peaceful assembly as well as hampered the growth of democracy in Nigeria
Design and construction of a pelton wheel turbine for power generation
Get PDFDesign and construction of a pelton wheel turbine for power generation is under taken. The pelton wheel turbine is a type of impulse turbine which under the atmospheric pressure and on this head which lies in the range of 200m. The pelton wheel turbine is an axial flow turbine. This work includes among other things the change in design parameter such as the change in discharge of water by which the velocity of jet changes due to change on the force exerted by the jet on the bucket which is responsible for the bucket movement which means the change in the speed of the runner with respect to the change in the jet velocity. The speed of the runner changes by two methods: first, is to change the discharge as well as the jet velocity which can be done by change in head and second, is the modification in the runner. Here the method used is changing the jet velocity by running at different and various height of 2.3m, 2m and 1.45m to ensure that experimental and calculations are made and graphical analysis obtained from the designed values

Development of the Kinetic Parameters for Enhanced Production of Ethylene Glycol in a Continuous Stirred Tank Reactor
Get PDFThis research aims to optimize the kinetic parameters of the ethylene glycol production process in a Continuous Stirred Tank Reactor (CSTR) using Matrix Laboratory (MATLAB) simulations to enhance the efficiency of the process. Ethylene glycol is a petrochemical product that plays an essential role in various industries due to its applications in the production of paint, polyesters, synthetic waxes, plastics, coolants, and automotive radiators. As such, process industries have been making significant efforts to produce ethylene glycol more effectively. The proposed method involved the simulation of the CSTR process using MATLAB based on the principles of mass and energy conservation. The initial and final reaction kinetic parameters for the process were obtained from literature data and were optimized using an Excel spreadsheet and the simulation tool. The optimized kinetic parameters resulted in better performance characteristics as indicated by the profiles of temperature and concentration of ethylene glycol, which indicated a significant increase in the yield of ethylene glycol using the optimized parameters. The optimized kinetic parameters were found to be (21793kJ/mol and 88.9781g/mol) for activation energy, (0.044185-1 and 0.07035-1) for the pre-exponential factor, and (0.70% and 0.10%), (0.01% and 0.18%), and (0.87% and 34.10%) for the rate constant, temperature, and catalyst loading, respectively. These optimized parameters led to higher yields and purities of the target product, ethylene glycol, indicating that the optimization of kinetic parameters was an effective strategy for enhancing the efficiency of the ethylene glycol production process. The simulation of the CSTR process using MATLAB and the optimization of kinetic parameters showed promising results in enhancing the efficiency of the ethylene glycol production process. The model proposed in this research can be used as a basis for designing more efficient and cost-effective processes for ethylene glycol production and other chemical reactions in CSTRs
Optimization of the Electrical Properties of Green Synthesized Graphene/Polyester Nanocomposite
Get PDFGraphene nanoplatelets offer exceptional properties, yet the performance and electrical conductivity of their polymer nanocomposites are often unimpressive. To overcome these obstacles, this study produced graphene from rice husk (Gr.NPs) coated with orange juice-modified green-generated silver nanoparticles (Ag.NPs)/polyester nanocomposites. The Taguchi-grey analysis was used to optimize the conductive characteristics of the developed nanocomposite. The composite\u27s optimal performance blend was 7.5% Gr.NPs, 0.5% Ag.NPs, 100oC curing temperature, and 4ml orange juice. The remarkable electron mobility of Ag.NPs-Gr.NPs were attributed to the high electrical conductivity (2.08 x10-8 S/m), dielectric constants (5.95), and thermal conductivity (1.45 Wm-1K-1). The experimental grey relational grade of 0.615 was 95% of the way to the projected optimal grey relational grade of 0.724. This proved the sufficiency of the nanocomposite\u27s optimal blending components for the production of electrical property furthered composites
