EMPIRICAL ANALYSIS OF THE CAUSES AND EFFECTS OF INFLATION IN NIGERIA
This research work examined the causes and effects of inflation in Nigeria between 1969 and 2009 and what could be done to ameliorate the negative effects on the economy. The time series variables properties on some selected variables were examined using Augmented Dickey Fuller (ADF) Unit root test and co-integration analysis. The result revealed that the explanatory variables (money supply, growth rates, gross domestic product growth rates and expenditure revenue ratio) are not spurious but exchange rate of dollar to naira was non-stationary. The study also revealed that the gross domestic product growth rate is counter inflationary as against inflationary factors. Keywords: Inflation, Growth Rate, Economic Variables, Inflation Effects, Unit Root, Exchange Rates, Money Suppl

Motivational factors influencing citizens to use M-Government services: a case of Kenyan ministries
Conference paper presented at 2014 eLearning Innovations Conference and Expo-KenyaInformation Communication Technologies (ICTS) have offered a wide range of opportunities to transform traditional governance in ways government services are offered. Growing research demonstrates the potential of mobile communications to radically transform service delivery by the government. M-Government is therefore emerging as the next big wave for ICT use in the public sector. This paper is based on a research done in 2012 at @iLabAfrica in Strathmore University as part of findings from a Masters dissertation. The purpose of the study was to investigate the role of m-government projects on service delivery to citizens in Kenya in order to enhance public service delivery. One of the study objectives was to evaluate motivational factors that influence citizens to use m-Government services.
The study used a descriptive survey design and employed questionnaire and interview techniques to collect data. It was carried out in all the headquarters of 31 Ministries of the Government of Kenya in Nairobi County. Random sampling was used to select citizens in each Ministry. Purposive sampling was used to identify the government officials working in the ICT units. A questionnaire was designed to gather information. Data was analyzed and presented in frequency and percentage outcomes or tables. The findings reveal that most Kenyans contact the Government Ministries via Mobile phone mostly to enquire about a particular service, entitlement, or application. In terms of citizens’ awareness about m-Government services, 58.8% respondents were not aware of any m-Government services. Data on citizen interactions with m-government service reveals that the respondents on the whole had more negative experiences than positive experiences. This indicates that there is room for improvement in Kenyan service delivery. Kenyan citizens prefer services communicated or delivered via mobile phones because: relatively lower cost of mobile phone technology; access through shared usage and ownership; and mobile phones reach areas where there is no other ICT infrastructure.
Recommendations included: services must be easy to use with valuable and timely content in order to ensure the service is relevant for end users; true transformation needs governments to pay close attention to re-engineering processes, reforming institutions, and creating an environment for greater accountability and transparency.Information Communication Technologies (ICTS) have offered a wide range of opportunities to transform traditional governance in ways government services are offered.

Particle hemodynamics analysis of Miller cuff arterial anastomosis
AbstractObjectiveStudies of animal and human below-knee anastomoses with Miller cuffs indicate that improved graft patency results from redistribution of intimal hyperplasia away from areas critical to flow delivery, such as the arterial toe. We hypothesize that particle hemodynamic conditions are a biophysical mechanism potentially responsible for the clinically observed shift in intimal hyperplasia localization associated with better patency of the Miller configuration.MethodsComputational fluid dynamics analysis of vortical flow patterns, wall shear stress fields, and potential for platelet interaction with the vascular surface was performed for realistic three-dimensional conventional and Miller cuff distal end-to-side anastomoses. Sites of significant platelet-wall interaction, including elevated near-wall particle concentrations and stasis, were identified with a validated near-wall residence time model, which includes shear stress–based factors for particle activation and surface reactivity.ResultsParticle hemodynamics largely coincide with the observed redistribution of intimal hyperplasia away from the critical arterial toe region. Detrimental changes in wall shear stress vector magnitude and direction are significantly reduced along the arterial suture line of the Miller cuff, largely as a result of increased anastomotic area available for flow redirection. However, because of strong particle-wall interaction, resulting high near-wall residence time contours indicate significant intimal hyperplasia along the graft-vein suture line and in the vicinity of the arterial heel.ConclusionsWhile a number of interacting mechanical, biophysical, and technical factors may be responsible for improved Miller cuff patency, our results imply that particle hemodynamics conditions engendered by Miller cuff geometry provide a mechanism that may account for redistribution of intimal hyperplasia. In particular, it appears that a focal region of significant particle-wall interaction at the arterial toe is substantially reduced with the Miller cuff configuration
