Herbicidan control of water hyacinth at Ere, Ogun State: implications for fish production

A brief account is given of a pilot demonstration of the chemical control of water hyacinth (Eichhornia crassipes) at Ere (a channel) in Nigeria using the herbicide glyphosphate. Results suggest that there was an increase in the nutrient content of the channel after herbicide application. This implied an upsurge of available food for fish and other aquatic organisms within the channel after the herbicide application. The decaying water hyacinth mass which sinks into the medium is likely to boost nutrient content, promoting the growth of fish and other aquatic animals. It is concluded that herbicidal control of water hyacinth is possible, especially under specialists' management with the conservation of fish and other non-target aquatic organisms alongside improved fish productio

BOOSTING NON-OIL EXPORT REVENUE IN NIGERIA THROUGH NON-TRADITIONAL AGRICULTURAL EXPORT COMMODITIES: HOW FEASIBLE?

Available data indicated that, some traditional agricultural export commodities like cocoa and rubber have remained on Nigeria’s agricultural export list, while others like groundnut and coffee have almost disappeared from the export list. In the same vein, non-traditional agricultural export commodities like sesame seed and cashew nuts have started featuring prominently on the export list. In line with theory, the econometric analysis carried out confirmed that a major policy change, which can provide a boost for agricultural exports, is the depreciation of the real exchange rate. For all the agricultural export commodities analyzed in the study, the coefficient of the exchange rate was positive and highly significant

Determinants of behavior of inflation rate in Nigeria

Inflation is an important macroeconomic issue that has continued to dominate discussions at major economic fora over time. Governments all over the world are concerned about its rising trend because of its pervasive effect on economic performance. One intriguing fact about inflation is that it is both the cause and effect of certain policy actions of government. Several studies have been conducted on the effect of inflation on economic activities in developing and developed nations, but studies on its cause, particularly in developing nations, are scant. This paper aims at identifying major factors that cause inflation in Nigeria. Based on the autoregressive distributed lag (ARDL) estimation method, the study shows empirical support for significant impact of external debt, exchange rate, fiscal deficits, money supply and economic growth on inflation. It further shows previous period or lagged inflation rate as a significant determinant of current inflation rate. However, the study produced no evidence of significant longrun impact of interest rate on the rate of inflation in Nigeria. The study recommends economic reforms that target foreign exchange inflow through increased export trade, as well as a paradigm shift away from deficit budgeting. There is also a need for infrastructural and institutional reforms to eliminate or, at least, minimize the impact of structural inequity on output prices

Appraisal of Corporate Internal Governance Mechanism and Banks’ Metrics in Nigeria

This research work observed the relationship between corporate internal governance mechanism and the financial metrics of banks in Nigeria. Over the years, emphasis has been placed on the use of eff ective governance to instill corporate discipline in maximizing stakeholders’ value. Using the performance information of five quoted banks in the Nigerian Stock Exchange with an aggregate of forty-five observations spanning from 2011 -2019 sample years, this study sheds some light on the degree of linearity of corporate internal governance measures such as board size, board composition, board independence, and bank liquidity on financial metrics of banks in Nigeria. The method of analysis adopted is the panel regression involving fixed eff ect estimation techniques. The correlation coefficient was used to measure the degree of association between our governance variables and profitability indices; while a robust estimator involving panel corrected standard error was applied. The estimated result for board size and board independence reveals a significant lag eff ect on bank performance. Board composition appears to have a significant inverse relationship with bank metrics which further suggests a low acceptance and adherence to cooperate governance by most banks with its resultant adverse eff ect on the bank metrics. Also, a statistical inverse relationship between the board size of a bank and its metrics was observed which suggests that increasing the size of the board of directors of a bank does not guarantee its performance. Hence, the study recommends that there is need for the regulatory authorities to reassess the procedures for the appointment of directors to the board in order to ensure uniform standards; transparency, accountability and stability exist in these financial markets

The Balloon Foot ; A Rare Presentation Of Congenital Constricting Annular Band

We present a case of a rare manifestation of congenital constricting annular band (CAB) in the lower extremity resulting in a severe excessive swelling of the foot which we have termed Balloon foot. The ballooned foot is caused by a progressive deepening of the circumferential constriction into the soft tissue of the lower extremity in region of the ankle. Conventional Z-plasty staged surgical releases of the constriction band was unsuccessful in this case, probably due to extreme and sustained peripheral vascular compromise of the foot from the exerting tourniquet effect of the severe band. We highlight the presenting features and the poor treatment prognosis. Keywords: Balloon foot; Congenital Annular Band; Constriction ring. Annals of Biomedical Science Vol. 4 (1) 2005: pp. 42-4
