Does Facility Based Sexual and Reproductive Health Services Meet the Needs of Young Persons? Views from Cross Section of Ghanaian Youth  [PDF]
Jonathan Mensah Dapaah, Seth Christopher Yaw Appiah, Eric Badu, Bernard Obeng, Victoria Ampiah
Advances in Sexual Medicine (ASM) , 2015, DOI: 10.4236/asm.2015.53008
Abstract: The focus on facility based health setting to provide sexual and reproductive health to the youth has been tested in several settings and achieved varying results. This study examined whether facility based sexual and reproductive health services met the needs of Ghanaian youth. Adopting the descriptive cross sectional design, 170 youths between the ages of 10 and 24 were sampled. A three-stage stratified random sampling technique was adopted. The results of the study are presented using descriptive statistics. The study established that a total of 55.8% (95/170) of the youth had utilized at least one or more of a sexual and reproductive health service in life time. However, only 45.2% (43/95) of youth used or accessed sexual and reproductive health services from a facility based setting. Facility based sexual and reproductive health service provided specifically for the youth is very limited. This calls for the provision of out-of health facility services located within the communities and at strategic places while ensuring confidentiality to the youth. More rigorous research is recommended on a national scale to examine youth preference for the type of facility based and out-of-facility based sexual and reproductive health services to meet the needs of young people.
Role of Stakeholders at Cape Coast PPAG Youth Centre: Deficiencies and Implications.
KG Badu
Edo Journal of Counselling , 2009,
Abstract: The study investigated whether the activities or the roles performed by the various stakeholders at the Cape Coast Planned Parenthood Association of Ghana (PPAG) youth centre impacted positively on the youth behaviour and performance at the centre. The sample comprised 22 teachers, 50 parents and 3 social welfare workers who were supposed to work with the centre. Data was collected with questionnaire and analysed with percentages. The results indicated that apart from the seemingly impressive recommendation role of stakeholders, all the other roles, namely, information, visitation, referral and follow-ups were found to be weak and ineffective and seemed to have little impact on the youth and the programme in general. It is recommended among others that long term educational campaign programmes should be mounted for all stakeholders on a regular and sustainable basis to achieve this desired goal. Key Words: stakeholders, youth, deficiency, quality care delivery, education.
Success Indicators for Selfbuild Houses in two Ghanaian Cities
DK Ahadzie, E Badu
Journal of Science and Technology (Ghana) , 2011,
Abstract: The recognition of success criteria for effective design and construction management purposes has been a topical issue in the housing construction industry for quite a while now. Yet, little is still known of the success indicators for SelfBuild houses, although these constitute the dominant mode of housing supply in many developing countries such as Ghana. To this effect, structured questionnaires were used to elicit from homeowners in two Ghanaian cities the importance they attach to a number of variables as determinants of success for Selfbuild houses, and the data analyzed using scale ranking and one-sample t-test. The analyses revealed that; adequate ventilation for thermal comfort (ranked no. 1), health and safety in the home (ranked no.2), quality of materials (ranked no. 3), quality of workmanship (ranked no. 4) and adequate daylight into rooms ranked (no. 5) are the main determinants of success in Selfbuild houses. The criteria cost and time received the lowest rankings of 10th and 11th respectively suggesting that while these traditional measures could be very important, in the long term they are not issues that Selfbuild homeowners might be particularly concerned about. The findings especially those relating to ventilation, health and safety in the home, quality of materials and adequate daylight are critical for dissemination to all construction professionals/practitioners regarding design decisions and choice of construction materials for Selfbuild houses in a tropical country like Ghana.
Evaluation of Stabilised-Earth (Tek) Block for Housing Provision and Construction in Ghana
RA Oppong, E Badu
Journal of Science and Technology (Ghana) , 2012,
Abstract: Lack of patronage of locally developed building materials has resulted in huge housing deficit and expensive housing construction in Ghana. Housing appears not to be serving as social good in Ghana. The new housing environments in Ghana are characterized by hitherto lesser known and exotic building materials. Through mapping of case study areas and ethno-narratology (narrative) approaches within the qualitative methodological paradigm, selected urban and rural communities were surveyed. Users’ perception of their houses and housing environments built of TEK blocks are presented in this paper. This paper speculates that TEK blocks as earth based building material can contribute to the alleviation of housing problems if there are conscious efforts of nationwide adoption of coordinated programmes and efforts.
Building Material Preferences in Warm-Humid and Hot-Dry Climates in Ghana
RA Oppong, E Badu
Journal of Science and Technology (Ghana) , 2012,
Abstract: This paper explores building materials preferences in the warm-humid and hot-dry climates in Ghana. Using a combination of closed and open-ended questionnaires, a total of 1281 participants (473 adults and 808 youth) were recruited in Ghana in a two-month survey in Kumasi and Tamale representing the warm-humid and hot-dry climates respectively. Sampling was purposive. The sample elements were chosen because they typically represented the communities of our case studies. Through hypothesis testing, the Pearson Chi-square results indicate a significant positive association between aesthetics and study areas (χ2 =155.65; df =4; N =1278; p < 0.05) with an asymptotic significance level of 0. 000 (p = 0. 0005). The findings indicate aesthetics generally appear to be major considerations instead of climatic considerations in the choice of building materials in Kumasi and Tamale. This paper concludes that, the preference for building materials in Ghana points to neglect of climatic considerations due to aesthetics influences and apparent lack of enforcement of building rules and regulations. This paper recommends a review of the National Building Regulations-Legislative Instruments 1630 to reflect current trends in architecture and building developments.

Food and Nutrition Sciences (FNS) , 2011, DOI: 10.4236/fns.2011.27107
Abstract: The objective of this study was to find out if the sawdust generated from some of the Ghanaian wood species can be used in the cultivation of pleurotus ostreatus (oyster mushroom) and their subsequent effect on the quality and yield of the mushrooms produced. Sawdust from three Ghanaian wood species (Triplochiton scleraxylon, Ceiba pentandra and Terminalia superba) were collected and their cellulose, hemicelluloses, lignin and nitrogen contents determined using standard methods. Triplochiton scleraxylon gave 46.76%, 15.69%, 27.55%, 0.01% w/w, Ceiba pentandra gave 44.79%, 15.32%, 34.08%, 0.02% w/w and Terminalia superba gave 46.64%, 16.29%, 31.17%, 0.02% w/w of the cellulose, hemicelluloses, lignin and nitrogen content respectively. Compost was then made from each of the wood and used as substrate for the cultivation of pleurotus ostreatus. The highest yield of mushroom was obtained from T. scleraxylon 334g followed by T. superba 277 g and C. pentandra gave the lowest yield of 193 g fresh weight after 3 flushes. The proximate composition of the mushrooms produced gave crude protein ranging 16.33 - 18.20, fat 1.67 - 2.07, carbohydrate 40.86 - 50.53, fibre 4.14 - 6.73 and ash content of 4.40% - 5.80%. The report has shown that the yield and nutritional content of the oyster mushroom on sawdust depends on the chemical constituents such as the cellulose content, the hemicellulose content, the lignin content, the nitrogen content of the particular substrate used. Triplochiton scleraxylon gave the best yield and nutritional content, considering that these substrates are freely available and regarded as “waste”, it can be used to cultivate edible mushrooms to supplement nutritional requirement and source of income to make life better for many people.
Towards an information provision strategy for university libraries in Ghana
Edwin Ellis Badu,Brendan Loughridge
Information Research: an international electronic journal , 1997,
Abstract: This article describes on-going research on the development of a library strategy for universities in Ghana. The research focuses on the factors affecting the development of a strategic planning process aimed at improving the libraries' capacity to deliver information services effectively and efficiently. Since the structure of universities in Ghana is, to a great extent, derived from or modelled on that of universities in the United Kingdom the project of necessity also includes some consideration of current attitudes to the strategic planning process in a number of university libraries in the United Kingdom. It is hoped that the study and evaluation of this aspect of the management of United Kingdom university libraries may provide pertinent guidelines for university library management in Ghana.
Spin relaxation in strained graphene nanoribbons: armchair vs zigzag edges
Sanjay Prabhakar,Roderick Melnik,Shyam Badu
Physics , 2014,
Abstract: We study the influence of ripple waves originating from the electromechanical effects on spin relaxation caused by electromagnetic fields in armchair and zigzag graphene nanoribbons (GNRs). By utilizing analytical expressions supported by numerical simulations, we show that it is possible to tune the spin flip behaviors ON and OFF due to ripple waves in GNRs for potential applications in straintronic devices. This finding is similar to recently made observations on the design of spintronic devices in III-V semiconductor quantum dots, where the sign change in the effective Land$\mathrm{\acute{e}}$ $g$-factor can be engineered with the application of gate controlled electric fields. In particular, we show that the tuning of spin extends to larger widths for the armchair GNRs than for the zigzag GNRs. Here we also report that the relaxation rate vanishes like $L^5$.

Abstract: Eggshells are among the emerging hazardous waste from the food processing industry. This work sought to valorize waste guinea fowl eggshells. Guinea fowl eggshells (GFEs) were evaluated in the production of CaO for chemical and industrial application. The functionality, thermal stability, elemental composition, phase distribution and surface morphology properties of uncalcined GFEs and GFEs calcined at 700°C, 800°C, 900°C, 1000°C and 1100°C were systematically studied by FTIR, TGA, XRF, XRD and SEM-EDX respectively. The elemental analysis revealed Ca as the main element in the GFEs. The uncalcined GFEs showed intense peaks that corresponded to calcite (CaCO3) phases. These transformed into Ca(OH)2 as the temperature of calcination increased and finally to CaO in the FTIR analysis. In the XRD diffractograms, the main peaks at 2θ values were 29.466° for the uncalcined GFESs and at 37.377° for the sample treated at 1100°C. The phases were confirmed as CaO when compared with JCPDS files. Using the Scherer equation, the CaO crystallite size for the sample calcined at 1100°C was found to be 50.68 nm along the (2 0 0) orientation. All the samples showed multi-step decomposition patterns in the thermogravimetric analyses (TGA), with weight loss of up to 47% for the uncalcined GFEs sample, which was mainly due to the transformation of the calcite (CaCO3) phase to CaO by removal of bound water, organic components, and CO2. Samples calcined at 1100°C showed mainly CaO phases in XRD analyses and fairly stable with 7% loss in weight after treatment at 800°C. SEM images of samples calcined at 900°C were irregular compared to samples treated at 1100°C. EDX data revealed that the surface structure was 100% calcium and oxygen. GFEs are a potential source of pure calcium oxide for various industrial uses.
Evaluation of striga-resistant early maize hybrids and test locations under striga-infested and striga-free environments
RO Akinwale, B Badu-Apraku, MAB Fakorede
African Crop Science Journal , 2013,
Abstract: Emergence of several seed companies in the West Africa sub-region during the last decade has necessitated intensified efforts towards hybrid development and extensive testing. The objectives of the present study were to evaluate selected Striga-resistant maize (Zea mays L.) hybrids for grain yield and stability of performance based on multiple traits. Thirty Striga-resistant single–cross maize hybrids plus two checks were evaluated under artificial Striga infestation and Striga-free conditions at 2 locations in Nigeria in 2008 and 2009. The two test locations possessed high discriminating ability. More promising genotypes were identified under Striga infestation based on multiple traits than based on yield per se, suggesting that grain yield alone is not a precise predictor of Striga resistance. Based on both biplot analyses, TZEI12 x TZEI25 was identified as the most outstanding in performance under both research conditions. Furthermore, TZEI11 x TZEI127 and TZEI80 x TZEI2B were identified as the most outstanding under Striga-infested conditions and TZEI60 x TZEI87 under Striga-free conditions by the two biplot methods. The hybrids with outstanding performance should undergo extensive multilocational testing and promotion for adoption for commercial production. Key Words: GGE biplot, multiple traits, Zea mays
