Determinants of University Working-Students’ Financial Literacy at the University of Cape Coast, Ghana
Abraham Ansong,Michael Asiedu Gyensare
International Journal of Business and Management , 2012, DOI: 10.5539/ijbm.v7n9p126
Abstract: This paper explores the determinants of university working-students’ financial literacy. It further seeks to establish the relationship between financial literacy and certain demographic characteristics. This study adopted a correlational research design as the framework to examine the relationship between variables without determining cause and effect. Data were randomly collected from 250 undergraduate and postgraduate students of a public university in Ghana. The paper found that age and work experience were positively related to financial literacy. Also, mother’s education was positively correlated with respondents’ financial literacy. However, level of study, work location, father’s education, access to media and the source of education on money were all not significantly correlated with financial literacy. A key recommendation is that given the positive correlation between mother’s education and financial literacy, parents should be actively involved in designing educational programs on financial issues at the basic and high school levels for their kids. It is believed that such a step forward will help parents to guard and guide their children’s financial behaviours.
Customers’ Perception of Innovative Banking Products in Cape Coast Metropolis, Ghana
Edward Marfo-Yiadom,Abraham Ansong
International Journal of Business and Management , 2012, DOI: 10.5539/ijbm.v7n3p162
Abstract: Competition and reforms in Ghana’s financial sector have brought about a lot of innovation into the Ghanaian banking industry. This study explores how innovative banking products are perceived by consumers. The study used purposive sampling technique to gather data from 288 students from a public university in Ghana. The study revealed that the critical features that influenced customers’ choice of banking products and their adoption were convenience, reliability, security, flexibility, time saving and ease of use. The most popular innovative products were Automated Teller Machines and E-zwich. Telephone banking and credit cards were not very popular. The mean preference for innovative banking products for female (15.0568) was slightly higher than that of male (14.7100). The mean usage of female (8.7955) was slightly higher than that of male (8.350). Due to the low usage of products such as the telephone and internet banking, it is recommended that banks in Ghana should embark on an educational campaign to highlight the benefits of these products to the populace.
Overweight and hypertension among college of health sciences employees in Ghana
R Aryeetey, J Ansong
African Journal of Food, Agriculture, Nutrition and Development , 2011,
Abstract: Healthcare workers, by virtue of their greater access to information, are expected to have less risk of obesity, hypertension, and other health outcomes often linked to lifestyles. However, there is limited evidence on practices and status of personnel who work in the healthcare setting about hypertension and overweight in Ghana. The current study tests the hypothesis that overweight and hypertension rates, as well as related risk factors among staff and faculty of the College of Health Sciences (CHS), University of Ghana, will be more positive than among the lay public. In June and July 2009, a cross-sectional self-completed survey was administered to 141 male and female faculty and staff of the College of Health Sciences, University of Ghana, in Accra. A representative sample was selected by proportionate random sampling from all seven academic and research units of the CHS. Anthropometry and blood pressure measurements were taken with questionnaire data on lifestyle, dietary history, and socio-demographic variables. Overweight and obesity were diagnosed as BMI >25 and >30 kg/m2, respectively. Abdominal adiposity was estimated as waist hip ratio >0.80 (females) or >0.95 (males). Hypertension was diagnosed as diastolic or systolic blood pressure > 140 or 90 mm Hg, respectively. Mean age of respondents was 40.5 + 10.8 years; 43% were over-weight, including 13% obese. More than one-third of overweight respondents did not report an overweight body image. Abdominal adiposity and hypertension rates were 25% and 34%, respectively. Low rates of regular physical activity (25%) and consumption of fruits and vegetables (40%) were observed. Overweight (OR=3.83; p<0.01) and central adiposity (OR=4.8; p<0.01) were associated with significantly increased risk of hypertension. Being married was a significant predictor of overweight (p<0.05), abdominal adiposity (p<0.05), and hypertension (p<0.05). The study concludes that working in a healthcare environment or being a health worker does not diminish your risk of overweight and hypertension. It is, therefore, recommended that interventions addressing overweight and hypertension should place attention more on environmental modifications rather than awareness creation.
Kinetic studies on the pyrolysis of asphaltenes from different types of kerogens
Ansong Geng,Zewen Liao
Chinese Science Bulletin , 2000, DOI: 10.1007/BF02893785
Abstract: The pyrolysis kinetics of a series of asphaltenes, from different types of kerogens, are studied in this work. The results indicate that the distributions of activation energy are over a wide range for the asphaltenes from type I kerogens. There is still a large potential of hydrocarbon generation in case the activation energy is above 350 kJ ·mol 1. While the distributions of activation energy are comparatively over a narrow range for the asphaltenes from type II and in kerogens, there is a little or almost no potential of hydrocarbon generation with the activation energy above 350 kJ · mol 1 respectively. For the asphaltenes from some specific type of kerogens, the pyrolysis kinetics can be applied to marking their maturity. Furthermore, based on detailed discussions of the kinetics parameter frequency factor, the asphaltenes from type I kerogens are considered to be of great potential to regenerate oils, while the asphaltenes’ potential for oil-to-gas conversion tends to go down in order of primitive kerogen types of III, II and I.
Asphaltenes in oil reservior recovery
Zewen Liao,Ansong Geng
Chinese Science Bulletin , 2000, DOI: 10.1007/BF02886171
Abstract: Asphaltene is one of the important compositions in oil reservoirs, while it is also a major factor that causes difficulties in oil recovery and oil post-processings. Up to date, study on asphaltenes in oil recovery is still a bottleneck problem. In this paper, the advances of studies on asphaltenes are reviewed, and some directions for further studying are suggested. What is reviewed in the paper includes the precipitation studies of asphaltenes, the degradation studies of asphaltenes and the applications of asphaltene’s studying in oil recovery; furthermore, it is regarded as a promising direction to study the possible applications of asphaltene’s selectively decomposing by chemical reagents in oil recovery.
Determination of carbon isotopic composition of individual light hydrocarbons evolved from pyrolysis of source rocks by using GC-IRMS
Ansong Geng,Yongqiang Xiong
Chinese Science Bulletin , 2000, DOI: 10.1007/BF02893777
Abstract: The carbon isotopic composition of individual light hydrocarbons generated from source rocks that had been pyrolysed in vacuum glass tube were determined by using the GC-IRMS techniques. The results indicate that abundant CO2 in the pyrolysates has a remarkable effect on the determination of CH4δ13C. Running cryogenically with an initial temperature of 40°C can effectively eliminate the effect. In addition, it conduces to measuring the δ13C of C2+ hydrocarbons by increasing the injection volume and/or absorbing CO2 with the solution of sodium hydroxide. The above measures will help to get the carbon isotopic composition of C1–C7 components, which is of great significance for gas/source rock correlation and for study on the genesis of natural gas.
Are Weeds Hitchhiking a Ride on Your Car? A Systematic Review of Seed Dispersal on Cars
Michael Ansong, Catherine Pickering
PLOS ONE , 2013, DOI: 10.1371/journal.pone.0080275
Abstract: When traveling in cars, we can unintentionally carry and disperse weed seed; but which species, and where are they a problem? To answer these questions, we systematically searched the scientific literature to identify all original research studies that assess seed transported by cars and listed the species with seed on/in cars. From the 13 studies that fit these criteria, we found 626 species from 75 families that have seed that can be dispersed by cars. Of these, 599 are listed as weeds in some part of the world, with 439 listed as invasive or naturalized alien species in one or more European countries, 248 are invasive/noxious weeds in North America, 370 are naturalized alien species in Australia, 167 are alien species in India, 77 are invasive species in China and 23 are declared weeds/invaders in South Africa. One hundred and one are classified as internationally important environmental weeds. Although most (487) were only recorded once, some species such as Chenopodium album, Poa pratensis and Trifolium repens were common among studies. Perennial graminoids seem to be favoured over annual graminoids while annual forbs are favoured over perennial forbs. Species characteristics including seed size and morphology and where the plants grew affected the probability that their seed was transported by cars. Seeds can be found in many different places on cars including under the chassis, front and rear bumpers, wheel wells and rims, front and back mudguards, wheel arches, tyres and on interior floor mats. With increasing numbers of cars and expanding road networks in many regions, these results highlight the importance of cars as a dispersal mechanism, and how it may favour invasions by some species over others. Strategies to reduce the risk of seed dispersal by cars include reducing seed on cars by mowing road verges and cleaning cars.
Determinants of Saving among Low-Income Individuals in Rural Uganda: Evidence from Assets Africa  [PDF]
Gina A. N. Chowa, Rainier D. Masa, David Ansong
Advances in Applied Sociology (AASoci) , 2012, DOI: 10.4236/aasoci.2012.24037
Abstract: Although research has shown that poor people in sub-Saharan Africa (SSA), including those living in rural areas save, little is known about the factors that influence saving and asset accumulation among this population. Using three theoretical perspectives on saving and asset accumulation, this study examines the broader determinants of saving and asset accumulation among low-income individuals in rural Uganda. Compared with the individual-oriented and sociological perspectives, institutional theory explains a large part of the variance in saving outcome among rural, low-income households. Wealth, proximity to financial institutions, financial education, and financial incentives are positively associated with higher saving performance. Findings suggest that poor people can and do save, particularly when institutional barriers to saving are removed. Institutional structures, which encourage low-income individuals to save, may contribute to a poverty reduction policy that shifts from just income supplementation to a more inclusive wealth promotion policy that assists people in creating their own pathways out of poverty.
The Drug Regimen Prescribed for Sickle Cell Patients Attending a Clinic in Kumasi, Ghana, in a Period of One Year  [PDF]
Kwabena Nsiah, Alex Osei-Akoto, Daniel Ansong
Open Journal of Blood Diseases (OJBD) , 2014, DOI: 10.4236/ojbd.2014.44007
Abstract: Objective: In order to manage the varied pathophysiological features of sickle cell disease (SCD), an array of drugs has to be used. The specific drugs used, however, depend on the locality. This study was aimed at finding out the drug regimen prescribed by clinicians to sickle cell disease patients who attended a Sickle Cell Clinic in Kumasi, Ghana. Method: The setting for the study is the Sickle Cell Clinic at the Komfo Anokye Teaching Hospital, Ghana, and a questionnaire was used as the study instrument. Information on drug prescription on each day of clinic visit was extracted from the medical records of the patients. Results: The drugs prescribed were “routine drugs” for SCD patients, analgesics, narcotics, anti-malarials, antibiotics, haematinics and miscellaneous drugs. The top ten commonly prescribed drugs were folic acid, diclofenac, ibuprofen, B-complex, routine drugs, artesunate/amodiaquin, paracetamol, penicillin V, amoxiclav and zincovit. Conclusion: Within the year, the drugs prescribed included those that could prevent vitamin and zinc deficiency due to continuing haemolysis, those that could mitigate the pain and inflammation from vaso-occlusion and reperfusion injury, as well as antibiotics to combat infections. Being a malarial-endemic region, prophylaxis with daraprim and symptomatic malaria fever therapy were common practices. This study has thus shown that the well-being of SCD patients in our typical tropical terrain, depends on haematinic vitamin/mineral supplements, anti-malarials, analgesics-anti-inflammatory, antipyretics and antibiotics.
Influenza prevention can help meet wider public health objectives  [PDF]

Health (Health) , 2012, DOI: 10.4236/health.2012.430147
Abstract: Influenza burden: Influenza imposes a major burden on people and public health systems, causing millions of severe cases and up to one million deaths annually. Much of this burden is borne by those aged 65 or over, children under 2 years of age and people with non-communicable chronic diseases, such as heart and lung conditions and diabetes. In the elderly, influenza can have longer-term effects beyond acute infection, with some facing increased disability and care requirements. Prevention: Taking into account the growing elderly population worldwide and their susceptibility to non-communicable conditions as well as rising healthcare costs, public health policies are increasingly focusing on disease prevention strategies and promotion of healthy ageing initiatives. Influenza vaccination has an important role to play in these approaches. Immunization of high-risk groups is recommended by public health organizations, both internationally and locally within many countries. However, although vaccines are considered the most effective method for preventing influenza, many high-risk people remain unvaccinated. Improving vaccination rates: In recent years, research has focused on increasing vaccine coverage. The results demonstrate the key role healthcare professionals play in encouraging immunization, alongside factors such as communication, education and financial support for vaccination. Paradoxically, although vaccination recommendations often include healthcare professionals and studies demonstrate the potential protection offered to workers and patients, many remain unvaccinated. As a result, a growing number of organizations, particularly in North America, are implementing policies requiring vaccination of healthcare pro fessionals as a patient safety measure. In summary: Influenza vaccination has a key role to play in helping to protect the health of the growing elderly population, reduce the burden associated with non-communicable diseases and decrease the annual toll on public health. Improving vaccination levels relies on the support of healthcare professionals, and increasingly healthcare professional immunization is considered an integral part of patient care.
