Inheritance of fresh seed dormancy in groundnut
AJ Yaw, A Richard, O Safo-Kantanka, HK Adu-Dapaah, S Ohemeng-Dapaah, A Agyeman
African Journal of Biotechnology , 2008,
Abstract: Pre-harvest sprouting in groundnut (Arachis hypogaea L) seeds belonging to sub species fastigiata is undesirable since it leads to substantial loss of seeds, both in quantity and quality. A short period of dormancy is therefore desirable in this sub-species to reduce such losses. This study was conducted to determine the heritability of fresh seed dormancy in groundnut and to transfer this trait from exotic lines (ICGV 86158 and ICGV 87378) known to posses dormancy, into the genetic background of two groundnut varieties (Shitaochi and Aprewa) widely grown in Ghana but lack dormancy. Freshly harvested seeds of mature pods from parents, F1, F2 and the backcross populations were assessed for their dormancy by incubating in petri dishes in the laboratory. The F1 progenies from crosses between dormant and non-dormant parents were dormant. The F2 progenies fitted the expected 3 dormant to 1 non-dormant ratio. The study showed that seed dormancy is controlled by monogenic inheritance with dormancy dominant over non-dormant.

African Journal of Biotechnology , 2008,
Abstract: Groundnut production and utilization in Ghana has tripled in the last decade due to its high nutritive value and the number of uses it can be put into. The chemical quality of seeds of Ghanaian groundnut are different from those of other countries, however, no previous studies has been done. This study was initiated to examine the nutritional quality of 20 groundnut varieties grown in Ghana. Dry samples were examined for oil content, crude protein, total carbohydrate, calcium, potassium, magnesium, sodium, zinc, copper, iron and manganese. Results from these analyses showed significant variation between the parameters measured. Virginia cultivars which belong to subspecies hypogaea had higher oil content (49.7%) than the Spanish and Valencia market types, which belong to subspecies fastigiata (47.3%). The mean protein content of subspecies fastigiata was however higher (25.69%) than subspecies hypogaea (22.78%). The mineral elements examined were substantial in reducing malnutrition especially in young and growing children. Broni fufuo, a Spanish market type had the highest crude protein content (30.53%) and the least oil content (33.60%) and is idea for products which require more protein and less oil. Substantial genetic variability exists for chemical composition and nutritional traits which could be utilised for various food preparations and selection for breeding purpose.
Efficiency Measurement Using a “True” Random Effects and Random Parameter Stochastic Frontier Models: An Application to Rural and Community Banks in Ghana  [PDF]
Michael Danquah, Alfred Barimah, Williams Ohemeng
Modern Economy (ME) , 2013, DOI: 10.4236/me.2013.412093

In this paper, we attempt to compare the results of stochastic frontier models that control for unobserved heterogeneity in the inefficiency model, and unobserved (parameter) heterogeneity in the production model respectively. We estimate a “true” random effect, and random parameter stochastic frontier models in a panel data framework. An application of these models is presented using data of rural and community banks in Ghana from 2006 to 2011. Our results show that the two models address the issue of unobserved heterogeneity, and therefore omitted unobserved heterogeneity in the production model may always show up in the estimated inefficiency.


Life Satisfaction among Elderly Households in Public Rental Housing in Singapore  [PDF]
Kwame Addae-Dapaah, Quah Shu Juan
Health (Health) , 2014, DOI: 10.4236/health.2014.610132
Abstract: We set out to investigate how satisfied the poor elderly Singaporean households in social housing are with their lives, especially in relation to their housing, in an attempt to find measures to improve, where possible, the life satisfaction of this group of elderly Singaporeans. We use archival and empirical research for our investigation. The results from 403 respondents to our survey are analyzed through logistic regression and factor analysis. We find that the life satisfaction of the elderly residents of social housing is very low. Furthermore we find that home modification that meets the requirements of the respondents will substantially improve their life satisfaction. Given that these elderly households neither have the right nor financial means to modify their housing units and precincts, it is incumbent upon the government, through the relevant authorities such as HDB, Town Councils and BCA to effect the necessary home modifications to create a more elderly-friendly physical environment to improve the life satisfaction of the elderly households in social housing in Singapore. This arguably is a social imperative which should not be subjugated to economic niceties as social housing is not a luxurious housing choice but the last safety net for basic shelter.

Agricultural Sciences (AS) , 2018, DOI: 10.4236/as.2018.94029
Abstract: The study was conducted to evaluate the field performance of local plantain genotypes; Apem, Oniaba, Apantu (AAB) and FHIA 21 (AAAB) suckers that were raised in containers (polybags) and their corresponding conventional suckers. Half of the containerized and conventional suckers in each plot were mulched with empty fruit bunch (EFB). Survival rate three months after transplanting was higher in containerized (100%) than conventional materials (60%) with or without mulching. Mulching increased the girth at flowering and total leaf area by 8% and 28% respectively, and reduced the number of days to flowering. Mulching also increased yield of plantain and the highest was recorded in FHIA 21. Bunch yield of container raised suckers per hectare was 19% greater than conventional suckers, due to higher survival rate after transplanting. Bunch yield among the genotypes in decreasing order was as follows, FHIA21 (20.7), Oniaba (16.9), Apem (15.9) and Apantu (13.2) tons/ha. Mulching increased the yield components such as, pulp weight, peel weight, finger weight and number of fingers. Genotypic variation in pulp yield was in the following decreasing order Apantu > FHIA 21 > Oniaba > Apem fresh weight. The pulp to peel ratio was in the following decreasing order Apantu > FHIA 21 > Apem > Oniaba. It is concluded that raising plantain suckers in polybags and applying EFB mulch is an improved production technique.
Improving bambara groundnut productivity using gamma irradiation and in vitro techniques
HK Adu-Dapaah, RS Sangwan
African Journal of Biotechnology , 2004,
Abstract: In recent times efforts are being made to improve the productivity of bambara groundnut. Studies were initiated (i) to characterise and evaluate landraces and to select superior ones for irradiation, (ii) to induce genetic variation through gamma irradiation and (iii) to use biotechnological approaches to shorten the generation cycle. The results of the study indicated that gamma irradiation induced higher genetic variation of up to four times within the varieties used in the study compared to the unirradiated control. Bambara groundnut yield could be increased through selection for number of pods per plant. Using the in vitro plus in vivo system and embryo axis explants, over four generations per year were obtained compared to 1 or 2 in the field. All the plants were morphologically normal and fertile. The shorter duration, high efficiency and genotype independency makes this system well suited for wider biotechnological applications in bambara groundnut. This novel approach is being applied to the variants/mutants obtained from gamma irradiation.

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.

Abstract: Most young person will become sexually active before their 20th birthday having to battle with early and unplanned pregnancies, unsafe abortions, maternal deaths and injuries. This study examined young person’s sexual knowledge, attitudes and practices and their levels of utilization of sexual reproductive health. Our study progresses beyond current research of reporting only sexual behaviour among youth to have insight into sexual and reproductive health update drivers yielding new empirically robust results for the Ghanaian case for sexual and reproductive health service uptake. The descriptively cross sectional design was employed in sampling 170 youth (150 surveyed and 20 Interviewed) using the stratified sampling technique together with a purposive selection of one key informant. Test of significance and associations were performed with the Chisquare test. In all 45.2% (77/170) of youth (10 - 24) had had sexual experience in life time. In respect of in-school youth, 42% (63/150) had had sexual experience whiles 70% (14/20) out-of-school youth had had sexual intercourse in life time. A total of 28.8% (49/170) of all the youth had sexual intercourse in the last six months with only 40.1 (20/49) using condom for protection. Parental discussion of contraceptive methods (29.3%) and sexual and romantic relationship (28.0%) was the least sexual and reproductive health area discussed among in-school youth. Youth knowledge of the available sexual reproductive health service was statistically associated with reproductive health service utilization (X2 = 0.00, P ≤ 0.05). A concerted effort is required from government, NGO, Civil society organizations and religious bodies to help translate youth knowledge about sexual health into responsible sexual life and protective sex.
A Review of Plan Implementation Management Practices in the Bekwai Municipality in the Ashanti Region of Ghana  [PDF]

Current Urban Studies (CUS) , 2016, DOI: 10.4236/cus.2016.42011
Abstract: Implementation is very vital in planning. This crucial aspect of planning (implementation) can only be achieved when appropriate goals and definite objectives are translated into executable strategies. This study aims at evaluating projects planning, implementation and management processes in the Bekwai Municipal Assembly, highlighting their strength and weakness and coming out with recommendations to inform future policy formulation. The case study designs with a sampled population of 310 participants, involving 300 household heads and unit committee members who were enrolled for the study. The study purposively engaged 10 participants from key units within the Assembly’s structure. The results of study demonstrate poor, unsatisfactory level of participation of concerned stakeholders at the grass root level in plan preparation and implementation. The study established that, statutory funding for the Assembly was not forthcoming. At the time of the conduct of the study, the District Assembly Common Fund, the major source of delegated funds for capital expenditures of the various MMDAs had been in arrears for over the past year. Notwithstanding these challenges, the Assembly has consistently been performing tremendously well in the FOAT (Functional Organizational Assessment Tool. Community level involvement in monitoring and evaluation of developmental projects was non-existing as none of the community members and unit committee members indicated their engagement in project monitoring and evaluation. Harnessing the resources potentials and opportunities of the Municipal remains the way forward towards expanding the revenue base of the municipality. Concerned stakeholder involvement is key to facilitating development. This could be done by adopting technologically inclined models such as mobile texting, employing the services of information vans and radio stations. The objective of realizing development project sustainability would be met if communities’ level education is provided on the need for their participation in plan preparation, implementation and management in a symbiotic manner.
