Mentoring and employee performance improvement in public hospitals in rivers state

Abstract: This study examined the relationship between mentoring and employee performance improvement in public hospitals in Rivers State. The study adopted the cross-sectional survey in its investigation of the variables. Primary data was generated through structured questionnaire. The population of the study was 810 employees of twenty Public Hospitals in Rivers State. The sample size was 265 determined using the Taro Yamen’s sample size determination formula. The reliability of the research instrument was achieved by the use of the Crombach Alpha coefficient with all the items scoring above 0.70. The hypotheses were tested using the Spearman’s Rank Order Correlation Statistics. The tests were carried out at a 95% confidence interval and a 0.05 level of significance. Results of hypotheses tests revealed that there is a positive significant relationship between mentoring and employee performance improvement in public hospitals in Rivers State. The study concluded that mentoring significantly predicted employee performance improvement in public hospitals in Rivers State. The study recommended that management of public hospitals should craft a successful mentoring strategy that will focus on the developing critical employee skills, capacities and competencies which will enhance employee performance improvement.

Effect of Soil Microbes on Nitrate, Phosphate and Total Hydrocarbon Content of Various Concentrations of Oilfield Wastewater

Abstract: The effects of soil microbes on nitrate, phosphate and total hydrocarbon content of various concentrations of oilfield wastewater were investigated for a period of 28 days using standard methods. Periodic sampling of the treatment options from each flask were carried out after 24 hrs and subsequently at 7 days interval for nitrate, phosphate and total hydrocarbon content analysis. The nitrate, phosphate and total hydrocarbon content were higher in all the treatment options than in the control (0%). The concentration of nitrate and phosphate in the soil treatment options reduced significantly at day 28. Total hydrocarbon content of the 0% (control) on 24 hrs was 48 mg/kg and 26 mg/kg on 28th day, while 10, 25, 50 and 75 (%) were 160 and 98, 162 and 94, 163 and 98, 163 and 96 mg/kg respectively. There was significant reduction between the incubation period (24 hr and 28 days) in the various treatment option including the control. The results revealed that nutrients (nitrate and phosphate) were been utilized by the soil microbes and further enhanced microbial utilization of hydrocarbons. This suggests that oilfield wastewater could serve as nutrient enhancement medium for indigenous soil microbes in bioremediation process.

Factors affecting performance of permeable groins in channel bank erosion control

Abstract: The factors affecting the performance of permeable groins are investigated by an analytical approach supplemented with field observation. These factors are broadly divided into three classes: (1) the properties of the soil where the groin is embedded; (2) the flow characteristics of the river channel that are imposed on the groin; and (3) the makeup of the groins. Factors relating to the properties of the soil and flow are then combined into an expression for the factor of safety against failure by overturning. This enables a deterministic sensitivity technique involving partial differentiation of the factor of safety with respect to each contributory factor to be applied. The results obtained show that depth of the groin is the most critical factor that determines groin stability. The depth is followed by flow velocity and discharge, unit weight of water, unit weight of soil, and cohesion. This order of importance agrees with the analysis of observed groin performance in a pilot project at Kaiama in the Niger delta.

Indigenous Technologies Fishing Settlement Response to Climate Change Variability’s in Southern Nigeria

Abstract: The study focused on indigenous technologies used by fishermen in southern Nigeria as adaptation measures to climate change variability’s. Interview schedule was used to elicit information from sixty respondents in three (3) communities using simple random sampling technique. Percentage and mean scores were utilized for data analysis. The study established that the climate change experiences were: rise in sea level, rise in temperature, high wind, change in tidal pattern and frequent storms. The effects of climate change experiences on fishing include low fish catch, increase in boat mishap, reduced fish production and low growth rate of fishes. Indigenous technologies used as mitigating steps include building of bigger boats, the use of diverse fishing gears and observation of weather. These technologies had been very effective as mitigating steps. The study recommended mainly that modern weather forecasting facilities should be provided for the fishermen.
