Trends in eclampsia at Korle Bu Teaching Hospatal, Accra Ghana
R Acquah-Arhin, EY Kwawukuwe
Nigerian Journal of Clinical Practice , 2003,
Abstract: Objectives: The aim of the study was to find out the current trend of eclampsia and the incidence in Korle Bu Teaching hospital Method: Case files of all patients who were managed as eclampsia from 1st January 1998 to 31st December 200 were reviewed Result: The incidence of eclampisa during the study period was 15.82 per 1000 deliveries and the fatality rate for eclampsia was 4.78%. About 36.25 of the patients did not receive any form of magnesium sulphate and about 47.5% of the patients arrived at the hospital in taxicabs Conclusion: The results suggested that the incidence of eclampsia had risen from 11.1to 15.82 per 1000 deliveries. It was concluded that magnesium sulphate should be made available in the district hospitals and the polyclinics. Protocol for its use should be circulated and enforced. In addition the ministry of Health could organize a pool of ambulance services for reasonable fees for the public. KEY WORDS: Eclampsia, Magnesium sulphate, maternal deaths.

Conceptualizing child labour trafficking and exploitation: The case of Roma children in Montenegro
Arhin Antonela
Temida , 2012, DOI: 10.2298/tem1203161a
Abstract: Trafficking of children for labour exploitation is a profit-oriented criminal activity by which children are recruited, transported, harboured or received for the purpose of labour exploitation irrespective of whether or not force, abduction, fraud or other means were used. This paper examines child labour trafficking in the context of human rights violations and as the worst form of child labour. In an attempt to situate the discourse of alleged labour exploitation and trafficking of Roma children in Montenegro, focusing in particular on instances of child begging, this paper offers an overview of the international legal framework as well as the Government of Montenegro’s policy framework relevant to this issue; an analysis of implicated historical, familial and cultural structures; and focuses on identifying root causes in terms of push-pull factors that are associated with enhancing children’s vulnerability and proneness to exploitation. Along with a set of recommendations, in closing, the paper calls for a more sophisticated analysis of child labour trafficking and, in the case of Roma children, a more nuanced understanding of historical and cultural pretexts against the backdrop of labour trafficking.

Abstract: pment of a prompting method to promote adolescent mother/infant verbal interactions using bug-in-the-ear-feedback Original Research (4679) Total Article Views Authors: Afua Ottie Arhin Published Date November 2008 Volume 2008:1 Pages 21 - 26 DOI: http://dx.doi.org/10.2147/PRBM.S4119 Afua Ottie Arhin Grambling State University, Grambling, LA, USA Abstract: It has been documented that adolescent mothers are less verbally and emotionally responsive in their interactions with their children compared to adult mothers. These less than optimal adolescent mother/infant interactions have been found to affect the child’s healthy growth and development. This small study aimed to identify and characterize the frequency of verbal behaviors exhibited in the infant/adolescent mother dyad during feeding sessions during a baseline phase of a study that employed single subject methodology. An individualized bug-in-the-ear feedback and prompting parent training model was instituted in the intervention phase of the study to improve the frequency and quality of infant-mother interaction. Results of the study clearly revealed low frequency of verbal interaction in the baseline phase. After a structured prompting intervention was instituted there were positive effects in the mother’s behaviors which in turn positively impacted infant behavior.

Hydrogeological and Hydrochemical Assessment of Basin Granitoids in Assin and Breman Districts of Ghana  [PDF]

Journal of Geoscience and Environment Protection (GEP) , 2018, DOI: 10.4236/gep.2018.69004
Abstract: Hydrogeological and hydrochemical assessments were carried out in Assin and Breman districts of Ghana. A multi-criteria approach was used in the assessment of the basin granitoids including; electrical resistivity survey, pumping test and water quality analysis. A total of twenty-five (25) representative boreholes were drilled, developed and pumped; obtaining data for aquifer hydraulic parameters estimation. Correlation analysis was used to determine relationships that exist between aquifer hydraulic parameters. Schoeller, Piper, Stiff plot and Gibbs diagrams were used to determine the hydrogeochemical facies, water types and the mechanism that control groundwater quality. The statistical analysis determined that aquifer hydraulic parameters discharge rate (Q), hydraulic conductivity (K) and Transmissivity (T) showed a strong positive correlation with specific capacity (Q/Sw) with R value 0.8462, 0.8738 and 0.8332 respectively. The K and T were respectively between 0.02 - 0.90 m/day and 0.36 - 13.47 m2/day with mean of 0.24 m/day and 3.03 m2/day respectively. The K values indicate a hydrogeological condition of aquiclude with relatively low permeability and medium water bearing capacity. The aquifer T magnitude is very low to low, groundwater potential is adequate for local water supply with limited and private consumption. All physicochemical parameters were within the permissible limits of Ghana Standards Authority (GSA) and World Health Organisation (WHO) except for apparent colour, pH, Fe and Mn. Distribution of major ions in groundwater samples was calculated and the general trend among cations and anions was found to be Ca2+ > Na+ > Mg2+ and Cl > HCO3 > SO42 respectively. The study area shows five main water types namely; Ca-HCO3, Na-Mg-HCO3-SO4, Ca-SO4, Na-Cl and Mg-Na-Cl. Weathering of rock-forming minerals as the mechanism controlling the groundwater chemistry. Microbiological parameters were above the permissible limits. Groundwater is suitable for drinking after treatment with chlorination, aeration and slow sand filtration methods.

ON THE COMPARISON OF BAYESIAN INFORMATION CRITERION AND DRAPER'S INFORMATION CRITERION IN SELECTION OF AN ASYMMETRIC PRICE RELATIONSHIP: BOOTSTRAP SIMULATION RESULTS
Henry de-Graft Acquah,Joseph Acquah
Russian Journal of Agricultural and Socio-Economic Sciences , 2013,
Abstract: Alternative formulations of the Bayesian Information Criteria provide a basis for choosing between competing methods for detecting price asymmetry. However, very little is understood about their performance in the asymmetric price transmission modelling framework. In addressing this issue, this paper introduces and applies parametric bootstrap techniques to evaluate the ability of Bayesian Information Criteria (BIC) and Draper's Information Criteria (DIC) in discriminating between alternative asymmetric price transmission models under various error and sample size conditions. The results of the bootstrap simulations indicate that model selection performance depends on bootstrap sample size and the amount of noise in the data generating process. The Bayesian criterion clearly identifies the true asymmetric model out of different competing models in the presence of bootstrap samples. Draper's Information Criteria (DIC; Draper, 1995) outperforms BIC at either larger bootstrap sample size or lower noise level.
Traditional Cloth Dyeing Enterprise at Ntonso: Challenges and Opportunities
SB Acquah, KA Oduro
West African Journal of Applied Ecology , 2012,
Abstract: There is a growing awareness to the threats posed by synthetic dyes. Natural plant-based dyes have proved to be important alternatives to synthetic dyes in the textile industry. The study investigated the traditional cottage textile dyeing enterprise at Ntonso, in the Ashanti Region of Ghana, to identify challenges facing the industry. Data were collected through questionnaire administration, individual and group interviews, and from secondary sources. A total of 40 proprietors were randomly selected and interviewed at Ntonso. The results indicate that the textile dyeing enterprise is confronted with a number of challenges, including default in payments by clients, poor quality of some natural dyes on the market and lack of interest of financial institutions to support expansion of the business. The dyers have, over the years, utilised only two tree species as sources of textile dyes. However potential exists for natural dyes from many plants. But many of these potential dye-yielding plants have not been investigated for colour production and performance on cloths for use in the textile industry. Systematic investigation into the dye-yielding potential of these species and their practical application and performance in the industry would boost the industry in Ghana.
On the Comparison of Akaike Information Criterion and Consistent Akaike Information Criterion in Selection of an Asymmetric Price Relationship: Bootstrap Simulation Results
H. D. Acquah
AGRIS on-line Papers in Economics and Informatics , 2013,
Abstract: Akaike’s Information Criteria provide a basis for choosing between competing approaches to testing for price asymmetry. However, very little research has been undertaken to understand its performance in the price transmission modelling context. In addressing this issue, this paper introduces and applies parametric bootstrap techniques to evaluate the ability of Akaike Information Criteria (AIC) and Consistent Akaike Information Criteria (CAIC) in distinguishing between competing asymmetric price transmission models under various error and sample size conditions. Bootstrap simulation results suggest that the performance of the model selection methods depends on sample size and stochastic variance. The Bootstrap simulations further indicate that CAIC is consistent and performs better than the AIC in large bootstrap samples. The ability of the model selection methods to identify the true asymmetric price relationship decreases with increase in stochastic variance. The research findings demonstrate the usefulness of Bootstrap algorithms in price transmission model comparison and selection.
