Determinants of sexual dysfunction among clinically diagnosed diabetic patients
William KBA Owiredu, Nafiu Amidu, Huseini Alidu, Charity Sarpong, Christian K Gyasi-Sarpong
Reproductive Biology and Endocrinology , 2011, DOI: 10.1186/1477-7827-9-70
Abstract: Sexual functioning was determined in 300 consecutive diabetic men (age range: 18-82 years) visiting the diabetic clinic of Tema General Hospital with the Golombok Rust Inventory of Sexual Satisfaction (GRISS) questionnaire, between November, 2010 and March, 2011. In addition to the socio-demographic characteristics of the participants, the level of glycosylated haemoglobin, fasting blood sugar (FBS) and serum testosterone were assessed. All the men had a steady heterosexual relationship for at least 2 years before enrolment in the study.Out the 300 participants contacted, the response rate was 91.3% after 20 declined participation and 6 incomplete data were excluded All the respondents had at least basic education, 97.4% were married, 65.3% were known hypertensive, 3.3% smoked cigarettes, 27% took alcoholic beverages and 32.8% did some form of exercise. The 69.3% SD rate observed in this study appears to be related to infrequency (79.2%), non-sensuality (74.5%), dissatisfaction with sexual acts (71.9%), non-communication (70.8%) and impotence (67.9%). Other areas of sexual function, including premature ejaculation (56.6%) and avoidance (42.7%) were also substantially affected. However, severe SD was seen in only 4.7% of the studied population. The perceived "adequate", "desirable", "too short" and "too long intra-vaginal ejaculatory latency time (IELT) are 5-10, 5-10, 1-2 and 15-30 minutes respectively. Testosterone correlates negatively with glycated haemoglobin (HBA1c), FBS, perceived desirable, too short IELT, and weight as well as waist circumference.SD rate from this study is high but similar to that reported among self-reported diabetic patients in Kumasi, Ghana and vary according to the condition and age. The determinants of SD from this study are income level, exercise, obesity, higher perception of "desirable" and "too short" IELT.Some of the consequences of diabetes include various medical [1], psychological [2], and sexual [3] dysfunctions. Among diabetic
Solution Focused Brief Therapy Applied to Diverse Classroom Settings in a Four-Year University  [PDF]
Charity Perry
Creative Education (CE) , 2014, DOI: 10.4236/ce.2014.522218
Abstract: Solution Focused Brief Therapy was developed during the late 1970s and 1980s by Steve de Shazer and his colleagues. The purpose of this paper was to examine the application of Solution Focused Brief Therapy’s parallels with the author’s classroom experiences in a higher education setting that gave special considerations to the author’s disciplines of sociology, critical thinking, and marriage and family therapy. More specifically, the unique experiences are brought to a classroom by students much in the same manner that individuals bring experiences to a therapist who practices Solution Focused Brief Therapy. The author concludes that the perception of what constitutes a problem can be expressed as a limitation, not just merely defined as a problem.
Family Systems Perspective and Diabetes Type I: Reflective Analysis  [PDF]
Charity Perry
Advances in Applied Sociology (AASoci) , 2015, DOI: 10.4236/aasoci.2015.511025
Abstract: The purpose of this paper is to reflectively explore diabetes from a family systems perspective. Specific discussion will involve current understanding of Type I Diabetes and Family Systems, understanding suffering of illness experience, and will provide comparison and contrast of effective behavioral interventions for families under the care of a marriage and family therapist. While moving expectations toward systemic understanding of Type I Diabetes will be explored, and a brief account of the researchers’ personal and present familial history within the discipline of marriage and family therapy will also be discussed.
Study of Urban Heat Island Trends to Aid in Urban Planning in Nakuru County-Kenya  [PDF]
Charity W. Kimuku, Moses Ngigi
Journal of Geographic Information System (JGIS) , 2017, DOI: 10.4236/jgis.2017.93019
Abstract: Urban Heat Island (UHI) is a phenomenon characterized by higher surface and atmospheric temperatures in urbanized areas as compared to the surrounding rural areas. This phenomenon is a consequence of increase in Land Surface Temperatures (LST) as a result of trapped heat energy on the surface. The objective of this study is establishing the trends in and relationship between LST and land use/land cover in Nakuru County as it seeks to achieve the ultimate goal to contain the UHI effect. Urban heat island inference was based on the generation of a time series set of Landsat imagery, with particular emphasis on the thermal band. Land use/land cover mapping was conducted using maximum likelihood classification techniques, and this, like the LST, is generated in a time series fashion from 1989 to 2015. Accuracy assessment was conducted in order to give confidence in the classification results. The accuracy of the development was assessed using observed temperature data as recorded by the ground stations at the Kenya Meteorological Department. This study employed Normalized NDVI and NDBI to investigate the variation land use/land cover. Results revealed that over the years, settlement has been on an upward trend in terms of area whereas forests have been decreasing due to deforestation. Also, the land surface temperatures have been increasing over the years. In order to qualify this, the correlation between LST and Land Use change was conducted and it indicated that changes to settlement/urban increased proportionately with Land Surface Temperature.
Nucleic-Acid-Binding Chromophores as Efficient Indicators of Aptamer-Target Interactions
Kwabena Sarpong,Bhaskar Datta
Journal of Nucleic Acids , 2012, DOI: 10.1155/2012/247280
Abstract: The binding affinity and specificity of nucleic acid aptamers have made them valuable candidates for use as sensors in diagnostic applications. In particular, chromophore-functionalized aptamers offer a relatively simple format for detection and quantification of target molecules. We describe the use of nucleic-acid-staining reagents as an effective tool for detecting and signaling aptamer-target interactions. Aptamers varying in size and structure and targeting a range of molecules have been used in conjunction with commercially available chromophores to indicate and quantify the presence of cognate targets with high sensitivity and selectivity. Our assay precludes the covalent modification of nucleic acids and relies on the differential fluorescence signal of chromophores when complexed with aptamers with or without their cognate target. We also evaluate factors that are critical for the stability of the complex between the aptamer and chromophore in presence or absence of target molecules. Our results indicate the possibility of controlling those factors to enhance the sensitivity of target detection by the aptamers used in such assays. 1. Introduction Over the past two decades, the principles underlying nucleic acid structure and the polymeric characteristics of oligonucleotides have been exploited for creation of special ligand sequences that bind specific target molecules with high affinity and specificity [1, 2]. These special sequences or aptamers are discovered from combinatorial oligonucleotide libraries by iterative selection and amplification processes. The rationale for an iterative selection process is explained by the principles of systematic evolution of ligands by exponential enrichment (SELEX) [2]. SELEX has allowed the discovery of aptamers for a plethora of molecular targets including small molecules and proteins [3]. By virtue of their high affinity and specificity aptamers have emerged as a class of molecules that rival antibodies especially in diagnostic and biosensing applications [4]. In particular, aptamers address several shortcomings of antibodies such as the ability to function in nonphysiological buffers and temperatures and the ability to identify reporter molecules such as fluorescein at precise locations. In this regard, aptamer-based optical sensors are extremely attractive and have been the object of extensive research [5–8]. Molecular beacon-inspired optical assays require functionalization of the 5′- and/or 3′-termini of an aptamer with a fluorophore and a quencher. In the presence of or upon binding to the target,

Economics and Finance Review , 2011,
Abstract: The study employs binary logistic regression analysis to investigate the gender side of lending using crosssectional data from 198 credit unions collected from the Credit Union Association (CUA) of Ghana. Contrary to anecdotal and empirical evidence in the literature, evidence adduced in this paper underpins the conclusion that female borrowers are not better than their male counterparts. Consequently, the paper contends that lenders in Ghana should not expect any improvement in their loan repayment performance if they lend more to females. Instead, lenders who contemplate better repayment performance should strengthen their management and integrate group lending into their lending operations.
Forecasting Milled Rice Production in Ghana Using Box-Jenkins Approach
Nasiru Suleman,Solomon Sarpong
International Journal of Agricultural Management and Development , 2012,
Abstract: The increasing demand for rice in Ghana has been a majorconcern to the government and other stakeholders. Recentconcerns by the coalition for African Rice Development (CARD)to double rice production within ten years in Sub-Saharancountries have triggered the to implement strategies to boostrice production in the government. To fulfill this requirement,there is a need to monitor and forecast trends of rice productionin the country. This study employs the Box-Jenkins approach tomodel milled rice production using time series data from 1960to 2010. The analysis revealed that ARIMA (2, 1, 0) was thebest model for forecasting milled rice production. Although, aten years forecast with the model shows an increasing trend inproduction, the forecast value at 2015 (283.16 thousand metrictons) was not good enough to compare with the current productionof Nigeria (2700 thousand metric tons), the leading producer ofrice of rice in West Africa.
A Practice Centred Approach to Understanding Social Learning and Knowledge Creation in a “Community of Practice”
David Boateng Sarpong
International Journal of Business and Management , 2009, DOI: 10.5539/ijbm.v3n4p23
Abstract: Communities of Practice (CoPs) in organisation science are often described as ‘the shop floor of human capital’ where learning and knowledge creation which underpins innovation evolves. Adopting the Bristol area geocaching community as a case study, this paper draws on the ‘practice turn’ in contemporary social theory to study the everyday interaction of the community members in their situated practice. Taking the geocaching community and their practice as a collective unit of analysis, the study employed the qualitative methods of ethnographic interviewing, participant observation and content analysis of archival internet forum logs of members to extend our understanding of the performative processes of social learning and knowledge creations in CoPs. A conceptual framework showing how the interactions among actors and their artefacts and reflexivity in practice could lead to learning and knowledge creation that stimulates innovation in a CoP is presented as a modest attempt to improve our understanding of the dynamics of a CoP renewal and sustainability.
Production and Consumption of Corn in Ghana: Forecasting Using ARIMA Models
Nasiru Suleman,Solomon Sarpong
Asian Journal of Agricultural Sciences , 2012,
Abstract: This study describes an empirical study of modeling and forecasting production and consumption of corn in Ghana using ARIMA models. The study revealed that ARIMA (2, 1, 1) and ARIMA (1, 1, 0) were the appropriate models for forecasting production and consumption respectively. Our forecast showed an increasing pattern in consumption and production of corn. Despite the increase in production, government has to still invest money into corn production, motivate corn farmers, and implement good policies for better land tenure systems for corn cultivation to ensure that production always exceeds consumption to avoid importation of corn into the country. This is imperative because importation could lead to high prices of corn and increase inflation rate, hence affecting the economy of the country.
Modeling the Pattern of Reserve Money Growth in Ghana
Nasiru Suleman,Solomon Sarpong
Current Research Journal of Economic Theory , 2012,
Abstract: The role played by reserve money growth cannot be ignored in the development of a country. Thus, this study describes an empirical approach to modeling monthly reserve money growth in Ghana using SARIMA model. The result showed that ARIMA (0, 1, 1)×(0, 0, 1)12 model was appropriate for modeling the reserve money growth. This model has the least AIC of 608.91, AICc of 609.18, BIC of 616.44, RMSE of 6.33, MAPE of 16.90 and MAE of 4.39, respectively. Diagnostic test of the model residuals with the ARCH LM-test and Durbin-Watson test indicates that there is no ARCH effect and autocorrelation in the residuals respectively. Finally, a twenty eight months forecast with the model showed that from the middle of the year 2011 to December, 2012, there will be an increase in the reserve money growth. Hence, we recommend that the government and other policy holders should devise appropriate measures to slow the growth since the country is not experiencing low inflation.
