ABSTRACT

The performance of solar cells depends on their monochromatic photon-to-current efficiency. In this study a model of the monochromatic photon-to-current efficiency (MPCE) was develop following the relation: MPCE = Jsc x Voc x FF / Pi, using matlab.

At the end the mode of operation of the model was explained. The aim of this research is to promote the use of matlab in scientific study.

ABSTRACT

Produced water from four Delta State Community flow-stations [Ogulaha (A), Sokobolor (B), Iyokiri (C) and Okirika (D)] 10 miles apart were analyzed.  They contain 35.26ppm polycyclic aromatic hydrocarbon for A, 4.57ppm for B, 60.68 for (C) and 53.00 for (D).  pH values were 8.10 for A, 8.20 for B, 8.10 for C and 8.10 for D, tuibidity values were 63NTU for A, 51 for B, 47 for C and 66 for D.  BOD and COD were (310.00, 121.00, 201.31 and 231.21)ppm and (810.00, 710.00, 913.00 and 810.00) ppm respectively for samples A, B, C, and D.  Total organic carbon (mg/l) was 30.00, 154.00, 23.00 and 240.00 for the samples A, B, C and D.  The metal concentrations of iron, zinc, nickel, cadmium and lead were higher than accepted limits of World Health Organisation (WHO) and National Environmental Standard and Regulation Enforcement Agency (NESREA) while copper, chromium and manganese were within acceptable limits.

ABSTRACT

This study examines the implications of the economic crises in the achievement of the MDGs in Nigeria. The paper begins with a survey of theoretical issues relating to the origins of the crisis and ends by suggesting policy proposals that would facilitate the attainment of the goals. Result shows that the global economy is facing a crisis of monumental proportions which no doubt will refrain the economy from achieving the goals. The financial crisis cum economic meltdown put under threat not only the prospects for achieving the Millennium Development Goals (MGDs) but raises a real possibility of reversing some of the progress already made in chasing these goals. The study therefore recommends the need to make economic growth more broad-based and employment inducing so as to make a dent on poverty, and for the world trading system to guarantee trade justice such that the world’s poorest countries will stand the chance, with the right support, to set themselves on a sustainable path if the economy must enjoy the basic reasons for the formulation of the MDGs.

ABSTRACT

The Nigerian Insurance Industry is struggling with knowledge loss resulting from employee turnover like other public or private sector organizations, especially during downsizing of employees or during a period of re-engineering. Costs of recruiting, of lost productivity and training to replace employees can reach huge amount. In the insurance industry, trade secrets, confidential information and valuable ideas are part of the workforce knowledge. A sensitive ethics-related issue is the case of insurance agents leaving the employer, to transfer to a competitor insurance company, while trying to take along as many clients as possible from the old employer. The data and information collected for the paper were mainly through journals, books and observations offered by international organizations and individuals. This paper suggests different methods of minimizing the loss of expertise, customer contacts and product knowledge when key employees leave for another company within the industry. Recommendations such as, documenting invaluable critical knowledge from top experts and key personnel, before leaving the  company, conducting exit interviews, analyzing the work force strengths and encouraging knowledge sharing among the workforce were made to reduce this loss.

ABSTRACT

Organizations regardless of their types and sizes are bound to take decisions from time to time about their operations .All functions performed in the organization( profit or not for profit) are decision-oriented.   The object of this paper is to highlight the various theoretical backgrounds as regards decision making which sometimes, eventually leads to the achievement of organizational goals and objectives .This paper also considered existent models of decision making and various managerial levels at which decisions are made. The paper was concluded that managerial decision making styles such as participative, consultative and democratic can enhance organizational effectiveness and efficiency.  It was recommended that routine decisions should be delegated, experts’ opinions should be gotten for technical decisions and that all stakeholders should be consulted and carried along during decision making.

ABSTRACT

Enterprises in the business world today are faced with enormous competition from both their immediate and far environments. The whole world is shrinking into a village, which makes it possible for companies to sell their products and services to customers of different race, colour, background and status. Therefore, this paper aim to assess how companies grow into a world class one with their practices that distinguish them from their competitors. Manufacturing and service companies have ways of making themselves distinct by offering their customers satisfying products and services and this in turn, qualifies them for great financial reward and an image that transcends the homeland of these companies. Thus, ,assessing how they do that, via the motivating support of a National Body that spurs them into action, and how Nigerian firms can learn from this formed the bedrock of this paper.

ABSTRACT

This paper examines the financial performance of CSR and Non-CSR banks using financial ratios and frontier efficiency analysis. We got accounting information for banks in Japan, US and UK quoted on the FTSE4Good global index from Bankscope database. They include thirty-eight (38) financial and economic ratios based on variables such as Asset quality, Capital, Operations and Liquidity; that captured major scope of financial performance. In addition, we used a non-parametric linear programming technique known as Data Envelopment Analysis to create a piecewise linear frontier that helps to determine the efficiency levels for both a common and separate frontier analysis. First, we find a positive relationship between corporate social responsibility and financial performance. Banks that incorporate CSR have better asset quality; capital adequacy; and are more efficient in managing their asset portfolios and capital. Second, we also find that geographic location regulates the relationship between CSR and FP during economic contraction, such that the relationship differs across relationship and transactional banking models. The findings are to an extent consistent with prior analysis on the CSR-FP link.

Keywords: Corporate Social Responsibility, Financial Performance, financial ratios, frontier analysis, value creation.


RULE OF LAW IN NIGERIA AND CHALLENGES OF GOOD GOVERNANCE

ABSTRACT

Attempts to institute good governance in Nigeria have always proven problematic. It is agreeable that colonial rule imposed a type of governance in the country that was anti-people in nature. By the time the colonialists left, the. local political elites have imbibed the culture of this type of governance that puts premium on gaining political power without considerations to accountability, rule of law and consl1tutionalism This paper argues that there is a deficit of rule of law and good governance in the country today. This deficit can be corrected through a viable and virile civil society, but much is dependent on the role of a qualitative leadership
