Impact of Organisational Structure on Employee Engagement: Evidence from North Central Nigeria

In the current workplace, organizational structure assumes priority in the level of employee engagement. Therefore, well planned structure results in workers efficiency and organizations effectiveness. This study assessed the impact of organizational structure on employee engagement in North Central of Nigeria. Adopting a survey design, the research made used of primary data, collected mainly through administering a set of questionnaire to 196 management staff, supervisors and non-management staff of the selected manufacturing firms from Plateau state. The findings revealed that: there is significant positive relationship between decentralisation system of control and employee productivity; standardisation system of control positively affects employees' efficiency. The study concluded that decentralisation system of control is crucial to employees' productivity and organisational development; also enhance rapid delivery of employee services, to both the organization and customers. Standardisation system of control ensures employee efficiency and generates quality products that give competitive edge over the competitors in the global market Incentives as key factor also contribute immensely to employee commitment in workplace. The work recommended that organisations should always employ decentralization system of control; management should adopt decentralization and see it as mechanism that fosters effective customer delivery services. In addition standardisation should be embrace, support and adopt by organizations

Applications of 3-D Structural Interpretation and Seismic Attribute Analysis to Hydrocarbon Prospecting Over X – Field, Niger-Delta

Complexly faulted subsurface configuration is capable of causing erroneous deductions in the absence of a well packaged interpretation approach and workflow for an oilfield exploration programme, thus a well prepared analysis saddled on the use and integration of sufficient data is indispensable to the unravelling of complex field subsurface structure as the search for oil and gas progresses into deeper waters. Suite of signatures from wireline logs and seismic volume was employed to gain more insight into the complexities of the hydrocarbon hosting units within and outside the vicinity of well control in the X-field Niger Delta. Horizons and fault interpretation were carried out to produce subsurface structure maps. Amplitudes of the horizons mapped were extracted and were used to study the distribution of the hydrocarbon sand. Three hydrocarbon bearing reservoirs were delineated within the study interval, namely: ROJ A, ROJ C and ROJ D. Well to seismic tie revealed that these reservoirs tied direct hydrocarbon indicators (bright spots) on the vertical sections. The structure maps produced revealed a series of NW-SE and E-W trending growth faults and fault echelons, most of which dip to the south. Fault assisted closures were revealed at the southern part of the field, which correspond to the crest of roll over structures and possibly served as the trapping mechanism for the reservoirs. The reflection amplitude of the studied horizons shows a fine network of anomalies that can be correlated to the prediction of the lateral distribution of the hydrocarbon sand. The conclusion of the study was that the western part of horizon ROJ A is a highly prospective area as bright spots were observed in the region. Also in the adjacent southern direction of this horizon, hydrocarbon accumulations have been confirmed from wells. These gas sands are possibly trapped in anticlinal closures located in the same area. On the other hand, the results from the study of horizon ROJ C suggest development opportunities in the southern area. High amplitude gas sands are seen to spread to the south and stratigraphy was assumed to play a major role in hydrocarbon migration. The study over horizon ROJ D reveal likely geologic features like regional sand pinch outs and channels in the southern part of the field. Spectral decomposition interpretation was suggested to be used further in improving the delineation of the thin reservoir sand bodies and for better outlining of their geometries but was not available on the workstation used The study has shown the feasibility of integrating structural interpretation and instantaneous amplitude in prospect identification and reservoir prediction

Experimentation And Modeling Of Infective Treatment And Recovery Of HIV Patients (A Case Study Of Kwara State)

The outbreak and spread of diseases have been studied for many years. The ability to make predictions about diseases could enable scientists to evaluate inoculation/vaccination or isolation plans and may have a significant effect on the mortality rate of a particular epidemic. Therefore this research experimentation and modeling of infective treatment and recovery of HIV patients (a case study of kwara state) will studynbspnbsp the rate at which people contact the HIV, investigate how many people a person can infect at a particular point in time. , develop model for male and female with HIV, develop estimating functions for such a model and determine the control measures and sensitivities to change in parameter. Regression analysis, Chi ndash square and SIR model were use to analyse the data. Result of the analysis using regression analysis give the fitted model Y= 12.302 + 0.00009X and Y= 13.077 + 0.00007X for male and Female respectively. The result shows that the fitted model is adequate and the rate at which people contact HIV is increasing. Also chi - square analysis revealed thatnbsp contacts ofnbsp HIV is not depend on gender and that there are differences in respondents health when taking drugs recommended by health workers. Further analysis using SIR model shows that there will likely be epidemic on HIV and that 29% of the male that have HIVnbsp must be treated to avoid epidemicsnbsp 9% of the female that have HIV must be treated to avoid epidemics. And we recommend that Health Planner should administer enough drugsnbspnbsp to HIV patient on regular basis and Health Planner should educate people more on HIV and the preventive measure should be thought

Exchange rate volatility in Nigeria: Consistency, persistency & severity analyses

The adoption of the International Monetary Fund (IMF) Structural Adjustment Programme (SAP) in 1986 resulted in the transition from fixed exchange rate regime to floating exchange rate regime in Nigeria. Ever since, the exchange rate of naira vis-à-vis the U.S dollar has attained varying rates all through different time horizons. On this basis, this study examines the consistency, persistency, and severity (degree) of volatility in exchange rate of Nigerian currency (naira) vis-a-vis the United State dollar using monthly time series data from 1986 to 2008. The standard Purchasing Power Parity (PPP) model was used to analyze the long-run consistency of the naira exchange rate while the time series properties of the data was examined using the ADF and PP approach, the stationary process, and order of the incorporated series. The ARCH and GARCH models were used to examine the degree or severity of volatility based on the first difference, standard deviation and coefficient of deviation estimated volatility series for the nominal and real exchange rate of naira vis-a-vis the U.S dollar. The result indicated the presence of overshooting volatility shocks. The econometric analyses further revealed that the nominal and real exchange rates of naira vis-a-viz the U.S dollar are not with the traditional longrun PPP model. All the incorporated measures of volatility indicated presence and persistency of volatility in the nominal and real exchange rate for naira vis-à-vis U.S dollar in Nigeria. This however proves the ineffectiveness of monetary policy in stabilizing exchange rate and therefore, calls for the need of more tightened measures especially in controlling the high demand for foreign currency

Growth Pattern of Pseudomonas aeruginosa in different wastewater media

Restaurant wastewater are a major cause of environmental pollution with the indiscriminate release of the effluent to the environment resulting in blocking of drainages and eutrophication thereby causing serious threat to aquatic life. The growth pattern of a dietary rich oily wastewater degrading bacteria strain, Pseudomonas aeruginosa in different wastewater media composed to mimic the possible constituents of restaurant wastewater was investigated in this study. There was noticeable microbial growth in the synthetic and domestic wastewaters after 48h while the detergent wastewater and heated oil-detergent wastewater did not support the strain's growth. The decrease in the fat content with a corresponding increase in the ash content after 120h was due to the test strain's metabolic activity, which is slightly higher in domestic wastewater than the heated oil-detergent solution. Also, the potassium (K+), Mg2+, Fe2+ and Ca2+ contents increased within the same period in both media except in the domestic wastewater where the Ca2+ content reduced. Protease enzyme activity (46.440mM/min) was considerably higher in the domestic wastewater than lipase (3.322mM/min) and amylase activity (14.244mM/min) after 72 hours of incubation. The pristine genetic properties of Pseudomonas aeruginosa altered when cultured in various wastewaters probably due to variation in the composition of the substrates

Potency of Arati-Obd+ Organic Fertilizer on Plant-Parasitic and Free-Living Nematodes in Peppermint (Mentha Piperita L.) Field

Peppermint (Mentha piperita L.) is one of the most economical aromatic and medicinal crops useful in pharmaceutical and agro-allied industries globally. It is among the neglected crops currently receiving attention by organic agriculture experts in Nigeria. In view of the potential threat Plant-Parasitic Nematodes (PPN) pose to the crop, a study was conducted to appraise the effects of Arati-OBD+ organic fertilizer in the control of associated phytonematodes in a field in Abeokuta. Responses of Free-Living Nematodes (FLN) to the organic fertilizer were also recorded. The fertilizer was applied at 0 tha-1, 5 tha-1 or 10 tha-1, laid out in Randomized Complete Block Design with three replications. Five core soil samples were collected randomly from the rhizosphere at depth of 0-30 cm, once every month for the period of three months per plot. Soil samples per plot were bulked to form a composite sample from which 250 g sub-samples were obtained and assayed for nematode presence, type and numbers of each found. Results indicated that 11 genera of PPN were found in the organic peppermint tested. They included Helicotylenchus, Rotylenchus, Rotylenchulus, Meloidogyne, Longidorus, Aphelenchus, Radopholus, Tylenchulus, Ditylenchus, Hoplolaimus, Pratylenchus and some free-living nematodes. These nematodes varied significantly (P 0.05) across treatments. Application of Arati-OBD+ at 5 tha-1 and 10 tha-1 significantly (P 0.05) suppressed PPN compared with untreated (control) plots. Ditylenchus, Tylenchulus, Meloidogyne, Radopholus and Aphelenchus decreased by up to 100% (total control), Helicotylenchus by 73 - 50% and Rotylenchus by 60 - 33% in the treated plots while the FLN increased by as much as 18 - 47% in the soil following application 5 – 10 tha-1
