Acceptance of biotechnology and socialcultural implications in Ghana
Quaye, W.; Yawson, I.; Yawson, R.M.; Williams, I.E.
Despite major scientific progress in the application of biotechnology in agriculture, public attitudes towards biotechnology in general and genetically modified food (GM food) products in particular remain mixed in Africa. Examining responses on acceptance of GM food through a stakeholder survey in Ghana, it was established that half of the 100 people sample interviewed were not in favor of GM foods. To this group acceptance of GM foods would make farmers loose focus on the traditional ways of cultivation, putting the whole nation at the mercy of profit driven foreign companies who produce GM foods. In order to have clear and unbiased attitudes towards agricultural biotechnology in Africa, there is the need to substitute dominant ideologies in the way biotechnology research and dissemination are conducted in developed countries with tailormade methodologies in developing countries. This paper emphasizes the social dynamic force of food focusing on the need for social shaping of biotechnologies to reflect local and regional needs. Respondents' perceptions of GM foods suggest that food is seen as not just a commodity to be consumed but food has both cultural and national identities. Generally, people are identified by their consumption and nutrition lifestyles and therefore take pride in what they eat. A proposal is made to set biotechnology research agenda in the context of social choices; social scientific coalition of biotechnology with endogenous development pathways' as opposed to 'exogenous biotechnology research'. Also there is the need for adequate capacity building of the existing regulatory institutions to handle ethical and moral issues associated with biotechnology research since survey findings showed lacked of public confidence in them. © 2009 Academic Journals.

The main objective of the study is to compare the Newton–Cotes methods such as the Trapezium rule, Simpson 1/3 rule and Simpson 3/8 rule to estimate the area under the Lorenz curve and Gini coefficient of income using polynomial function with degree 5. Comparing the Gini coefficients of income computed from the Polynomial function with degree 5 for the Trapezium, Simpson 1/3 and Simpson 3/8 methods using the relative errors showed that the trapezium rule, Simpson’s 1/3 rule and Simpson’s 3/8 rule show negative biases with the Simpson 1/3 rule yielding the lowest absolute relative true error of 4.230711 %. © 2016, The Author(s).

Joint large deviation result for empirical measures of the coloured random geometric graphs
DokuAmponsah, K.
We prove joint large deviation principle for the empirical pair measure and empirical locality measure of the near intermediate coloured random geometric graph models on n points picked uniformly in a ddimensional torus of a unit circumference. From this result we obtain large deviation principles for the number of edges per vertex, the degree distribution and the proportion of isolated vertices for the near intermediate random geometric graph models. © 2016, The Author(s).

Reference intervals for common biochemical analytes in serum and plasma of a random adult population in the Greater Accra Region of Ghana
Asare, G.A.; Nortey, E.N.; Nkumpoi, T.; Amoah, A.G.B.
Background: The reference interval (RI) is arguably the most widely used decision making tool in clinical practice. Using the manufacturer's reference values may not be appropriate for other ethnic populations. Objective: The objective was to determine the reference intervals (RI) of Ghanaians and compare them to that provided in kits. Methods: 6300 adults, 2565 years were selected by cluster sampling from three communities in the Greater Accra Region, Ghana. A total of 4733 (male/female ratio = 1:1.5) participated. Fasting Blood Glucose (FF), 2hour postglucose plasma glucose (2HPP), total cholesterol (TCHOL), high density lipoprotein cholesterol (HDLC), low density lipoprotein cholesterol (LDLC), triglycerides (TG), uric acid (UA), urea (U), albumin (ALB), alkaline phosphatase (ALP) were measured. Results: Male and female mean ages were 44.9 ±14.7 and 44.0 ±14.6 years, respectively. Most assays had mean values between the 25th and 75th percentile apart from HDLC whose mean values fell within the 50th percentile. Thus half of the manufacturers RI (MRI) represented <25 percentile for FF, 2HPP, LDLC, ALB and ALP. The MRI for Urea was <25th  >97.5th. Conclusions: Mean values of most of the parameters determined represented the 25th75th and not the 95th or 97.5th percentile.
