Empirical Study of Barriers to Electronic Commerce Adoption by Small and Medium Scale Businesses in Nigeria

Electronic commerce (E-commerce) is a technological innovation that enables small to medium enterprises (SMEs) to compete on the same level with their larger counterparts. And it has the potential to improve efficiency and productivity in many areas and, therefore, has received significant attention in many countries of the world. A thorough analysis of the impact of the internet and e-commerce across firms, industries and economies is necessary to separate hype from reality. However, several researchers have called for the investigation of the association between the perceptions of e-commerce and the barriers to its adoption in developing countries. It is however on record that SMEs the world over are faced with significant challenges that compromise their ability to function and to contribute optimally to the respective economies where they operate. This study was conducted in three states of Nigeria (Lagos, Abuja and Enugu states) with the use of interviews to gather relevant data; the aim of which was to understand the challenges which serve as barriers to E-Commerce adoption by small and medium scale enterprises in the Nigerian context. Findings indicates that small and medium scale online present is at best unknown. The most common e-Commerce applications used by most SMEs include but not limited to the use of e-mails for communication purposes and a simple website for basic product information – information contained are usually outdated as most of these websites are hardly updated. Findings revealed, among others, that lack of and total absence of a regulatory framework on e-Commerce security, as well as technical skills, and basic infrastructures are some of the barriers to electronic commerce adoption. The findings however, provide a constructive insight to financial practitioners, governments as well as other stakeholders on the need to give e-commerce a place in all aspects of e-commerce activities

Downsizing as a Strategic Tool for Effective Organizational Management: A Case Study of Nigerian Banks

Downsizing, in recent years, have assumed a commonplace in various organisations. The views of various practitioners and in fact results of various studies indicates that these initiatives, albeit, intended to produce positive results, often do more harm than good to some organisations, workforce and their performance. The unending quest for lower costs, higher productivity and fatter profits have often led to the wielding of the ‘’big stick’’. Organisations of varying sizes and shapes have used downsizing as a cost cutting management strategy, however, the untold stories are the actual cost of these exercise to the organisation, performance and it’s far reaching implications to the workforce. This paper explored the costs and implications of the massive wave of redundancies in the workforce in Nigerian banks. With the help of data obtained from open-ended interviews conducted with various stakeholders in downsizing operations and applied within a clinical framework, individual reaction patterns are explored in the victims, the survivors and the executioners. Among the victims and survivors within the Nigerian setting, a number of ways of coping can be discerned, and described as compulsive, abrasive, dissociate and depressive. Findings revealed a plethora of mixed feelings among various employees and expose the far reaching implications both to the organisations, affected individuals (victims) and the psyche of their co-workers (survivors). The article ends with a number of practical recommendation

Scale-invariant moving finite elements for nonlinear partial differential equations in two dimensions

A scale-invariant moving finite element method is proposed for the adaptive solution of nonlinear partial differential equations. The mesh movement is based on a finite element discretisation of a scale-invariant conservation principle incorporating a monitor function, while the time discretisation of the resulting system of ordinary differential equations is carried out using a scale-invariant time-stepping which yields uniform local accuracy in time. The accuracy and reliability of the algorithm are successfully tested against exact self-similar solutions where available, and otherwise against a state-of-the-art h-refinement scheme for solutions of a two-dimensional porous medium equation problem with a moving boundary. The monitor functions used are the dependent variable and a monitor related to the surface area of the solution manifold

Long-term perturbations due to a disturbing body in elliptic inclined orbit

In the current study, a double-averaged analytical model including the action of the perturbing body's inclination is developed to study third-body perturbations. The disturbing function is expanded in the form of Legendre polynomials truncated up to the second-order term, and then is averaged over the periods of the spacecraft and the perturbing body. The efficiency of the double-averaged algorithm is verified with the full elliptic restricted three-body model. Comparisons with the previous study for a lunar satellite perturbed by Earth are presented to measure the effect of the perturbing body's inclination, and illustrate that the lunar obliquity with the value 6.68\degree is important for the mean motion of a lunar satellite. The application to the Mars-Sun system is shown to prove the validity of the double-averaged model. It can be seen that the algorithm is effective to predict the long-term behavior of a high-altitude Martian spacecraft perturbed by Sun. The double-averaged model presented in this paper is also applicable to other celestial systems.Comment: 28 pages, 6 figure

Lack of Effect of SU1498, an Inhibitor of Vascular Endothelial Growth Factor Receptor-2, in a Transgenic Murine Model of Retinoblastoma

SU1498, a tyrosine kinase inhibitor of vascular endothelial growth factor receptor 2 (VEGFR-2), has activity against retinal neovascular diseases. To determine if this drug might have clinical utility against retinoblastoma, we evaluated the effects of SU1498, as well as the expression of VEGFR-2, in a transgenic animal model of retinoblastoma. Optical coherence tomography (OCT) was evaluated as a technology to measure retinal tumors in vivo, in response to treatment. Immunofluorescence analysis was performed to evaluate the distribution and expression of VEGFR-2 in enucleated eyes from LHβTag transgenic mice and controls at 4, 8, 12, and 16 weeks of age. VEGFR-2 and phosphorylated (p)VEGFR-2 levels were quantitated by Western blot. OCT was used to pair 10-week-old animals based on tumor volume (n=10), and these animals were treated with 6 periocular injections of SU1498 (50mg/kg, given twice weekly) or vehicle for 3 weeks. Tumor burden was determined by histology and in vivo imaging by OCT. VEGFR-2 and pVEGFR-2 expression levels were upregulated during tumorigenesis. However, SU1498 did not significantly reduce tumor burden compared to vehicle (p=0.29). OCT imaging of one matched pair demonstrated equivalent, linear tumor growth despite treatment with SU1498. Retinal tumors can be followed non-invasively and quantitatively measured with OCT. VEGFR-2 is strongly upregulated during tumorigenesis in transgenic retinoblastoma; however, SU1498 does not decrease tumor volume in transgenic murine RB at the studied dose and route of administration

Projective and Coarse Projective Integration for Problems with Continuous Symmetries

Temporal integration of equations possessing continuous symmetries (e.g. systems with translational invariance associated with traveling solutions and scale invariance associated with self-similar solutions) in a ``co-evolving'' frame (i.e. a frame which is co-traveling, co-collapsing or co-exploding with the evolving solution) leads to improved accuracy because of the smaller time derivative in the new spatial frame. The slower time behavior permits the use of {\it projective} and {\it coarse projective} integration with longer projective steps in the computation of the time evolution of partial differential equations and multiscale systems, respectively. These methods are also demonstrated to be effective for systems which only approximately or asymptotically possess continuous symmetries. The ideas of projective integration in a co-evolving frame are illustrated on the one-dimensional, translationally invariant Nagumo partial differential equation (PDE). A corresponding kinetic Monte Carlo model, motivated from the Nagumo kinetics, is used to illustrate the coarse-grained method. A simple, one-dimensional diffusion problem is used to illustrate the scale invariant case. The efficiency of projective integration in the co-evolving frame for both the macroscopic diffusion PDE and for a random-walker particle based model is again demonstrated

Enhancement factor for the electron electric dipole moment in francium and gold atoms

If electrons had an electric dipole moment (EDM) they would induce EDMs of atoms. The ratio of the atomic EDM to the electron EDM for a particular atom is called the enhancement factor, R. We calculate the enhancement factor for the francium and gold atoms, with the results 910 plus/minus 5% for Fr and 260 plus/minus 15% for Au. The large values of these enhancement factors make these atoms attractive for electron EDM measurements, and hence the search for time-reversal invariance violation.Comment: 6 pages, no figures, uses RevTex, reference adde

A moving mesh finite element algorithm for the adaptive solution of time-dependent partial differential equations with moving boundaries

A moving mesh finite element algorithm is proposed for the adaptive solution of nonlinear diffusion equations with moving boundaries in one and two dimensions. The moving mesh equations are based upon conserving a local proportion, within each patch of finite elements, of the total “mass” that is present in the projected initial data. The accuracy of the algorithm is carefully assessed through quantitative comparison with known similarity solutions, and its robustness is tested on more general problems. Applications are shown to a variety of problems involving time-dependent partial differential equations with moving boundaries. Problems which conserve mass, such as the porous medium equation and a fourth order nonlinear diffusion problem, can be treated by a simplified form of the method, while problems which do not conserve mass require the full theory
