ABSTRACT

Organizations recently developed transaction processing technology that requires data captures in large amount and match the speed of processing of the data into information which can be utilized in making decision. Data mining, the extraction of hidden predictive information from large databases, is a newly powerful technology with great potential that help organisations to project on the vital information in their data warehouses. Machine learning is used for statistical and visualization techniques to discover and present knowledge in a form which is easily intelligible to humans. Data mining tools are used to predict future trends and behaviours, allow businesses to make proactive, knowledge-driven decisions. Most organisations received and store large volume of data about their businesses and most of these data are not used to analyse useful information form it due to inability to derive a viable information form it. Data mining tools can answer business questions that traditionally were too time consuming to resolve. They scour databases for hidden patterns, finding predictive information that experts may miss because it lies outside their expectations. Data mining tools support organisation to ascertain valuable information from the data set. To deliver a large volume of data in term of speed and accurate the use of data mining tools becomes paramount for effective and efficient useful of information of future prediction. Financial organisations in these days make use of computer as a tool for adequate and effective storage of information or data.

ABSTRACT

The goal of this paper is to obtain the unequal masses of the atoms moving in geometry of two component fermions system. The two component fermions systems have been considered. The fermion-dimer scattering length  and dimer-dimer scattering length  in the universal limit of large fermion-fermion scattering length  have been computed. The scattering properties of the fermion-dimer, dimer-dimer and the mass ratio dependence of the universal fermion-dimer and universal dimer-dimer scattering length have been analyzed. Scattering properties of composed system indicate a deep understanding of the dynamics in many-body of an atom system.

Key word: Atoms, fermion-fermion, fermion-dimer, dimer-dimer and Hamiltonian

ABSTRACT

Two major approaches have emerged as alternatives to classical bureaucratic government, the new Public management and the governance approach. Although both learn to some extent from each other and evolve by taking ideas from one another they, in many ways, can be positioned as opposites with which governments can tackle the increasing complexity of policy processes, implementation and service delivery. While the new public management focuses on getting the goals right and then leaves the implementation to separate bodies, governance is very much preoccupied with combining different perceptions on goals and tries to improve inter-organizational cooperation. This study compares both perspectives.

ABSTRACT

This study examines the relationship between foreign portfolio investment and economic growth in Nigeria from 1986 to 2018. Data for the study were gathered from secondary sources and analyzed with the use of both descriptive and inferential statistical methods. The Toda Yamamoto Non- Causality test was used to ascertain the nature of relationship between Foreign Portfolio Investment and economic growth.The impulse response and variance decomposition were used to examine the response of economic growth to innovations in foreign portfolio investment in Nigeria. The Toda Yamamoto Non- Causality result revealed that there is a bi-directional relationship between foreign portfolio investment and economic growth and the impulse response revealed that economic growth responded positively and permanently to shocks in foreign portfolio investment in Nigeria after the second period of forecast.  The study recommends that the government should encourage the inflows of foreign portfolio investment by making investment friendly policies that would attract foreign investment into the country. Also emphasis should be directed toward maintaining peace and avoidance of debt overhang.

ABSTRACT

This research paper examined the daily exchange rate of the South African (ZAR) and the Nigerian Naira (NGN) which starts from 11th March,2017 and 9thSeptember,2017 reveals an abrupt change on 4th August,2017 in further favour of the Rand. This change is significant as the pre-intervention series was stationary. The pre-invention series was modeled as ARMA(3,12) model using Augmented Dickey Fuller unit root test which was adjusted  to fit the model to be stationary. An intervention model was obtained and the post-intervention data closely agreed with the forecast data.

ABSTRACT

This study examinesthe relationship between organisational culture and the performance of employees in Nigerian organisations, as most of the focus has been on organisational performance.It focuses on specific cultural traits of involvement, consistency, adaptability and mission, using the Denison Organisational Cultural Survey model, involving 139 employees of 7 offices of large-scale organisations in Jos metropolis. The data collected through structured questionnaires were analysed using the Pearson Correlation Coefficient, validated by Linear Regression Analysis, which resulted to significant positive relationships being established between involvement, adaptability and mission and the performance measures of quality output/service delivery, quantitative target achievement and job satisfaction. However, when subjected to regression analysis, only involvement and adaptability were found to have significant effect on employee performance. These results have been discussed, with appropriate recommendations and suggestions made.

ABSTRACT

The problems of rising social vices and poverty is associated with the increase in unemployment especially among the youths in Nigeria, more youths graduate from tertiary institutions of learning only to face limited employment opportunities that are difficult to secure. One of the solutions to the problems of graduates’ unemployment in Nigeria is the promotion of entrepreneurship and venture creation among students in tertiary institutions with a view to prepare them to be job creators and not job seekers after graduation. Entrepreneurship can help reduce increasing rate of employment if encourage in the right way. The study seeks to find out the prospect and challenges of entrepreneurship and venture creation among graduates of tertiary institutions in Nigeria with Plateau state as a case study. Using the survey method of data collection, sample size of 800 questionnaires were administered, 720 were retrieved and 620 valid questionnaires were analysed after sorting. The questionnaire combined multiple choice closed and opened ended questions. A multistage sampling was adopted where the state is stratified into three senatorial zones, 4 Local Government Areas (LGA) from each of the senatorial zones were identified and graduates of tertiary institution were thereafter randomly selected. The study adopted the descriptive and evaluation methods of data analysis to analyse data gathered. Findings revealed that entrepreneurship opportunities exist in Plateau State and that more graduates are willing to venture into business creation provided there is an enabling environment. The findings also found that entrepreneurship and venture creation in Plateau state is faced with a lot of challenges among which include challenging environment for entrepreneurship practice and venture creation, limited access to start-up capital for intending graduates, unfavourable government policies, inadequate infrastructures especially in the rural areas among other challenges. The study recommendsentrepreneurship education be sustained in all tertiary institutions in Nigeria, creating enabling environment by policy makers to encourage new start-up business and small and medium enterprises, access to reasonable interest loan in financial institutions that is less stringent and infrastructures should be provided in the rural areas among other recommendations.
