Job Satisfaction of Academic Staff Members on Full-Time Appointment in South-Western Nigerian Tertiary Institutions

Man works to earn a living in an organization, and such work can be viewed as an instrument employed to achieve a lot of set personal goals and expectations. This study, therefore, examines job satisfaction of staff members on full-time appointment in South-western Nigerian tertiary institutions. It is a quantitative research in which a well-structured questionnaire was used to collect responses across eighteen tertiary institutions in South-western Nigeria. A purposive random sampling method was adopted to select a representative sample, and 880 questionnaires were properly selected and analyzed. The validity and reliability tests indicated that the measurement scales met the acceptable standards. Charts were used to present the biographic information of the respondents. The data obtained from the investigation were analyzed using Charts, Correlation Analysis, Regression Analysis and some relevant statistical tools. The findings have revealed a high factor of the academic staff’s dissatisfaction with opportunity available for self-development because of poor research environments. Moderate proportion has also revealed staffers’ satisfaction with their job. Factors leading to job satisfaction were also revealed. The study, therefore, suggests that Chief Executives of Nigerian tertiary institutions should focus on the identified factors leading to job satisfaction such as good remuneration and welfare package, appreciation and commendation, adequate facilities and teamwork etc. Implementing the aforementioned factors will definitely increase job satisfaction among the academic staff on full-time appointment, thus, reducing the friction rate and creating a stable and reliable teaching/learning environment for academic staff and the students.

Evaluation of Metal Pollution in Groundwater in the Industrialized Environs in and Around Dindigul, Tamilnadu, India

Synoptic hydrogeochemical assessments of physico-chemical and metal concentrations were analyzed to understand the driving forces behind heavy and trace metal pollution dynamics in groundwater systems of the heavily industrialized Dindigul district of Tamilnadu (India). Seasonality in solute dynamics is mainly due to regional differences in recharging capacity of groundwater systems and associated hydrogeochemical processes. Rapid changes in land use coupled with industrialization result in contamination of groundwater with heavy and trace metals like Be, Cr, Mn, Zn, Mo, Ni, Co, As, Cu, Cd, Pb, and Fe. The Pearson correlation and the Principal Component Analysis demonstrate that the complex suite of multidimensional metal pollution sources is influencing the groundwater quality in this region. In addition, pollution indices like heavy metal pollution index (HPI), heavy metal evaluation index (HEI), and contamination factor (Cd) were used to characterize the groundwater quality with reference to the water quality standards. All results demonstrate that the Dindigul groundwater quality is severely polluted by a large suite of metals like Be, Cr, Mn, Zn, Mo, Ni, Co, As, Cu, Cd, Pb, and Fe. Hence stringent management policies are highly required to control the industrial pollution and to improve the regional groundwater quality for sustainable development of the regional environment

Evaluation of groundwater quality in a rural community in North Central of Nigeria

Evaluation of water quality of nine boreholes and three open hand-dug wells in a rural community in North Central Nigeria revealed relative abundance of cations Na > k > Ca >Mg> Zn > Pb and anions Cl− > PO4 2 − > SO4 2 − > NO3− in the boreholes and cations Ca>Na>K>Mg>Pb and anions NO3− > PO4 2 − > SO4 2 − > Cl− in the wells. The major contaminants exceeding SON and WHO permissible limits were NO3−, Mg, TH, pH and Mg, Pb, TH, pH and DO in the wells and boreholes, respectively. They are attributable to anthropogenic sources such as domestic waste water and poor waste disposal and natural sources such as mineral dissolution from clayey aquifer which made the acidic groundwater unsuitable for consumption unless they are appropriately treated. Correlation studies revealed existence of three major mineral groups in the aquifer Ca-Fe group, Na-Mg group, Zn-K group, as well as a minor group Pb-group, and they determine the chemical composition of the groundwater and the ionic exchange between the groundwater and mineral-bearing clayey aquifer. In order to curb microbial contamination by Enterobacter aerogenes and Escherichia coli, it is recommended that proper latrines and drainages be provided while domesticated animals should be restricted from boreholes and well. Further, treatment with water guard and pur purifier is recommended
