The Support Needs of Nurses Caring for TB Patients at Tshilidzini Hospital in Limpopo Province, South Africa  [PDF]
Hulisani Matakanye, Augustine Kwame Tugli, Dorah Ursula Ramathuba
Open Access Library Journal (OALib Journal) , 2019, DOI: 10.4236/oalib.1105862
Tuberculosis (TB) is a disease which is caused by a relatively large, non-motile, rod-shaped pathogen called Mycobacterium tuberculosis. TB is a major cause of illness and death worldwide, especially in Asia and Africa. Despite the fact that TB is a curable illness, the tragedy is that TB remains the biggest killer in the world as a single pathogen. The purpose of this study was to describe the support needs of nurses caring for TB patients at Tshilidzini Hospital in Limpopo Province, South Africa. Qualitative, exploratory and descriptive designs were used. Purposive sampling method was used to select the participants. The personal support needs of six nurses caring for TB patients at Tshilidzini hospital were explored, and it was guided by data saturation. Data was collected through in-depth individual interviews, field notes were taken and data audio-recorded. Data was analysed using Colaizzi’s (1978) method of data analysis. Trustworthiness was ensured and ethical considerations were observed.The research findings revealed two major themes from the raw data: support structure available in the hospital and support needs for the nurses.The findings of this study revealed that nurses are in need of special support from the management. Therefore there is an urgent need to address this problem by the Department of Health, Hospital Executive Managers and Nursing Service Manager.
Performance Analysis of Image Smoothing Techniques on a New Fractional Convolution Mask for Image Edge Detection  [PDF]
Peter Amoako-Yirenkyi, Justice Kwame Appati, Isaac Kwame Dontwi
Open Journal of Applied Sciences (OJAppS) , 2016, DOI: 10.4236/ojapps.2016.67048
Abstract: We present the analysis of three independent and most widely used image smoothing techniques on a new fractional based convolution edge detector originally constructed by same authors for image edge analysis. The implementation was done using only Gaussian function as its smoothing function based on predefined assumptions and therefore did not scale well for some types of edges and noise. The experiments conducted on this mask using known images with realistic geometry suggested the need for image smoothing adaptation to obtain a more optimal performance. In this paper, we use the structural similarity index measure and show that the adaptation technique for choosing smoothing function has significant advantages over a single function implementation. The new adaptive fractional based convolution mask can smoothly find edges of various types in detail quite significantly. The method can now trap both local discontinuities in intensity and its derivatives as well as locating Dirac edges.
Las tecnologías multimedia y reforma educativa en áfrica: el caso de Ghana Making the Introduction of Multi-media Technologies Count in Education Reform in Africa: the Case of Ghana
Kwame Akyeampong
Comunicar , 2009, DOI: doi:10.3916/c32-2009-02-009
Abstract: La presente contribución da un repaso a la introducción de las tecnologías antiguas y nuevas de la información en el sector educativo de Ghana. Se ala cómo la reciente proliferación de las tecnologías mul timedia en el país ha alentado finalmente la introducción de las TIC en la educación. Sin embargo, el autor sostiene que buena parte de la motivación para introducir estas nuevas tecnologías en los centros educativos e institutos superiores no ha reflejado la necesidad de reconceptualizar las prácticas curriculares en la formación docente, con el fin de fundamentarlas en ideas constructivistas sobre los conocimientos y su producción. Sin esto, las reformas para introducir las nuevas tecnologías de información y comunicación en las aulas corren el riesgo de ser meramente herramientas que nuevamente se utilizan para reforzar las viejas tradiciones de ense anza y aprendizaje en base a la trasmisión de los conocimientos sin ningún pensamiento crítico. Finalmente, el autor insiste en que los cambios curriculares en la formación docente en Ghana, y en otras partes de áfrica, también deben reflejar las nuevas identidades de aprendizaje profesional y experiencias de aprendizaje que deben fomentar las TIC y otras herramientas mediáticas en el aula. This contribution reviews the introduction of old and new information communication technologies in Ghanaian education. It points out how the recent proliferation of multi-media technologies in the country has ultimately encouraged the introduction of ICTs in education. However, the author argues that much of the move to introduce these new technologies into schools and colleges has not reflected the need to re-conceptualise teacher education curriculum practices to base its foundations on constructivist ideas about knowledge and its production. Without this, reforms to introduce new information communication technologies in classrooms risk becoming tools that are again used to reinforce old traditions of teaching and learning based on uncritical transmission of knowledge. Finally, the author argues that changes to the teacher education curriculum in Ghana, and elsewhere in Africa, should also reflect the new professional learning identities and learning experiences that ICT and other media communication tools are meant to foster in the classroom.

The Effect of Contraceptive Practice on Fertility in Ghana: A Decade of Experience
Boadu, Kwame
Canadian Studies in Population , 2002,
Abstract: English This study examines some factors that influence fertility behaviour in Ghana,with particular emphasis on the influence of contraception as an intermediate variable. The decadeexamined covers the period 1988 to 1998 and the factors analyzed are age, residence, education,religion and ethnicity. Employing multivariate regression analysis and path models, the study observesthat among all the factors, age is the only variable that has a moderate effect on fertility. Also ofsignificant interest is that the positive influence of contraceptive use on fertility in 1988 isreversed in 1998. The study notes that given the non-significant effects obtained save the moderateeffect of age, it is not possible to draw a definitive conclusion regarding the impact that any ofthese factors might have contributed to the observed reduction in fertility during the period. Inlight of this, the study recommends that more effort would be required if fertility is to be reducedsubstantially. Nonetheless, the reversal in the effect of contraceptive use between the two periods isseen as encouraging. French Cette étude porte sur certains facteurs qui ont une incidence sur le comportement procréateur au Ghana. Une attention particulière a été accordée à l'influence de la contraception en tant que variable intermédiaire. L'étude porte sur la période allant de 1988 à 1998 et sur les facteurs tels que l'age, le lieu de résidence, l'éducation, la religion et l'ethnicité. Basée sur l'analyse de régression multidimensionnelle et des modèles causaux, l'étude fait remarquer que de tous les facteurs, l'age est la seule variable présente une conséquence modérée sur la fertilité. Il est également intéressant de noter que l'influence positive de la contraception en 1988 a été renversée en 1998. Les auteurs de l'étude soulignent que compte tenu des résultats peu importants obtenus, hormis l'effet modéré de l'age, il est impossible de tirer une conclusion définitive en ce qui concerne l'impact de ces facteurs sur la réduction de la fertilité observée pendant cette période. Compte tenu de cela, les auteurs recommandent une hausse des mesures si l'on veut réduire la fertilité considérablement. Quoi qu'il en soit le revirement des conséquences des pratiques contraceptives pendant les deux périodes est considéré comme encourageant.
Removal of Steriod Hormones by Activated Carbon Adsorption—Kinetic and Thermodynamic Studies  [PDF]
Augustine O. Ifelebuegu
Journal of Environmental Protection (JEP) , 2012, DOI: 10.4236/jep.2012.36057
Abstract: The mechanism, isotherms and kinetics of removal of two endocrine disrupting chemicals, 17β-estradiol (E2) and 17α-ethinyloestradiol (EE2) by activated carbon adsorption were investigated in an agitated non-flow batch adsorption studies. Mathematical models were used to describe the adsorption phenomenon with the kinetic and thermodynamic parameters evaluated using the adsorption equilibrium data at varying temperatures. Higher adsorption rates were achieved at acidic to neutral pH ranges, with the sorption kinetic data showing a good fit to the pseudo second order rate equation and the Langmuir adsorption isotherm model for both E2 and EE2. The Gibbs free energy were –16.68 kJ/mol and –17.34 kJ/mol for E2 and EE2 respectively. The values of enthalpy for both E2 (84.50 kJ/mol) and EE2 (90 kJ/mol) indicated a chemical nature of the sorption process. Both the isotherm and thermodynamic data obtained all supported the mechanism of adsorption of E2 and EE2 to be mainly chemisorptions supported by some physical attractions.
A Chi-Square Approximation for the F Distribution  [PDF]
L. Jiang, Augustine Wong
Open Journal of Statistics (OJS) , 2018, DOI: 10.4236/ojs.2018.81010
Abstract: F distribution is one of the most frequently used distributions in statistics. For example, it is used for testing: equality of variances of two independent normal distributions, equality of means in the one-way ANOVA setting, overall significance of a normal linear regression model, and so on. In this paper, a simple chi-square approximation for the cumulative distribution of the F-distribution is obtained via an adjusted log-likelihood ratio statistic. This new approximation exhibits remarkable accuracy even when the degrees of freedom of the F distribution are small.
Dynamic Systems of Shifts in the Space of Piece-Wise Continuous Functions  [PDF]
Isaac Kwame Dontwi, William Obeng-Denteh
Advances in Pure Mathematics (APM) , 2012, DOI: 10.4236/apm.2012.26067
Abstract: In this paper we embark on the study of Dynamic Systems of Shifts in the space of piece-wise continuous functions analogue to the known Bebutov system. We give a formal definition of a topological dynamic system in the space of piece-wise continuous functions and show, by way of an example, stability in the sense of Poisson discontinuous function. We prove that a fixed discontinuous function, f, is discontinuous for all its shifts, whereas the trajectory of discontinuous function is not a compact set.
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.

The Effects of Race and Space on City-County Consolidation: The Albany-Dougherty Georgia Experience  [PDF]
Kwame Boakye Dankwa, Timothy Sweet-Holp
Current Urban Studies (CUS) , 2015, DOI: 10.4236/cus.2015.33021
Abstract: In this paper the authors summarize the history of government consolidation successes and failures in Georgia, discuss regionalism and functional consolidation, and address social-structural barriers to unified government. The paper focuses on the 60-year consolidation movement and current unification efforts in Albany-Dougherty County, GA. Since knowing citizen perceptions is vital in understanding the resistance to consolidation, the paper concludes with findings from a 2012 Exit Poll in Dougherty County, GA.
