Khat: Is It More Like Coffee or Cocaine? Criminalizing a Commodity, Targeting a Community  [PDF]
Ezekiel Gebissa
Sociology Mind (SM) , 2012, DOI: 10.4236/sm.2012.22027
Abstract: This article looks at the expansion of khat chewing from the Horn of Africa to Western countries. It assesses the reaction of various sections of US society toward a practice they perceived as a dangerous new “drug” and a possible source of funding for terrorist groups by documenting the effect on Oromo immigrants of a nationwide crackdown by law enforcement. For the new immigrants, chewing khat provides a setting that connects them to the homeland and eases the vicissitudes of integration into the host culture, but the practice is illegal. It also shows how the media and political interest groups have shaped public perception of chewing khat in a negative light and precipitated the promulgation of hasty policies that have made Oromo immigrants targets of law enforcement. The article urges users to exercise discretion in a political environment that is not ready to restore fairness and rationality to policymaking.
Differentiation of neuronal cells using a murine embryonic stem cell-based method  [PDF]
Uthayashanker R. Ezekiel
Advances in Bioscience and Biotechnology (ABB) , 2013, DOI: 10.4236/abb.2013.49113

The differentiation and screening methodology proposed here is an efficient in vitro system to screen and study effects of small molecules and bioagents and is an alternative to studies that use live animals and embryos. The method is based on engineering a stable murine embryonic stem (ES) cell line expressing lineage-specific promoters that drive selection and reporter genes. Additionally, uniform embryoid bodies (EBs) are used for differentiation studies that allow synchronous differentiation. The reporter and selection marker genes are expressed only in lineages where the promoter is functional. The differentiated cell type can be identified by reporter gene expression and the selection marker can be used for selective enrichment of that particular cell population. The method described here is useful in screening small molecules or bioagents that can differentiate stem cells into particular lineages or cell types. Identified compounds are useful in areas such as stem cell-based regenerative medicine and therapeutics. The method described here has been applied to neuronal cell differentiation.

New Improved Variational Homotopy Perturbation Method for Bratu-Type Problems  [PDF]
Olusola Ezekiel Abolarin
American Journal of Computational Mathematics (AJCM) , 2013, DOI: 10.4236/ajcm.2013.32018

This research paper deals with the boundary and initial value problems for the Bratu-type model by using the New Improved Variational Homotopy Perturbation Method. The New Method does not require discritization, linearization or any restrictive assumption of any form in providing analytical or approximate solutions to linear and nonlinear equation without the integral related with nonlinear term. Theses virtues make it to be reliable and its efficiency is demonstrated with numerical examples.

Reducibility of Periodic Quasi-Periodic Systems  [PDF]
Evi Ezekiel, Sangram Redkar
International Journal of Modern Nonlinear Theory and Application (IJMNTA) , 2014, DOI: 10.4236/ijmnta.2014.31002

In this work, the reducibility of quasi-periodic systems with strong parametric excitation is studied. We first applied a special case of Lyapunov-Perron (L-P) transformation for time periodic system known as the Lyapunov-Floquet (L-F) transformation to generate a dynamically equivalent system. Then, we used the quasi-periodicnear-identity transformation to reduce this dynamically equivalent system to a constant coefficient system by solving homological equations via harmonic balance. In this process, we obtained the reducibility/resonance conditions that needed to be satisfied to convert a quasi-periodic system in to a constant one. Assuming the reducibility is possible, we obtain the L-P transformation that can transform original quasi-periodic system into a system with constant coefficients. Two examples are presented that show the application of this approach.

Africa, Poverty and Forces of Change: A Holistic Approach to Perceiving and Addressing Poverty in Africa  [PDF]
Tayo Raymond Ezekiel Eegunlusi
Open Journal of Philosophy (OJPP) , 2016, DOI: 10.4236/ojpp.2016.64035
Abstract: This work argues that Africa’s condition of poverty lingers because the continent fails to view poverty in its holistic sense in her attempts at tackling her economic challenges. Other types of poverty exist, such as mental poverty, moral poverty, emotional poverty, spiritual poverty, political poverty and social poverty, which pose great problems for the continent. Obviously, her failure to give worthwhile attention to solving these problems largely contribute to why she has not really benefited from her vast wealth of human and material resources. Also, this lack of holistic approach to perceiving poverty often allows Africa to be swayed by global forces of change such as socio-cultural factors, political factors, wars and terrorist activities, technological forces as information technology and electronic media, and so on. Consequently, majority of Africans seem to be blinded to the reality of possibility of redemption from the continents precarious economic condition. Thus, neglecting their nations, they emigrate abroad, under the guise of seeking enabling environment for productivity and survival. At the same time, those at the helms of affairs perpetuate the economic poverty status-quo by greedily enriching themselves. Thus, the con- tinent becomes an unfortunate victim of parochial perspectives as other continents become undeserving beneficiaries of her endowments and heritages. Using philosophy’s critical and argumentative methods of empirical, conceptual and historical analysis, this paper debates that a holistic perspective to poverty can help control global forces of change in ways that will favour Africa’s total development and enhance her profiting in the globalisation era.
Mental Alienation and African Identity: Exploring Historical Perspectives in Response to the Crises of African Societies  [PDF]
Tayo Raymond Ezekiel Eegunlusi
Open Journal of Philosophy (OJPP) , 2017, DOI: 10.4236/ojpp.2017.71001
This paper argues that the colonially-motivated alienation of the African mind, which plays a major role in the moral crisis, corruption, war and anarchy on the African continent, makes the possibility of a true African identity uncertain. Writers often premise African identity on historical, cultural and psychological factors but these factors now appear to be weak constituents of this identity because of severe crisis facing the moral and communitarian foundations on which this identity rests. The present problem of the African state is dual-natured. First is that her rich moral heritage of dignity, discipline, diligence, faithfulness, honesty and sound integrity is being eroded. Second is that the spate of intolerance sweeping across some parts of Africa, resulting from unmitigated acceptance of alien western doctrines inappropriate for her culture, grossly infests her systems with a high level of intolerance and anarchy capable of making her social order like Hobbes’ state of nature in which human life is “nasty, brutish and short.” These situations, worst still, have horridly affected the meaningful and constructive development of the continent and rank her people among the poorest in the world, despite her rich natural and human resources. Using the critical and argumentative methods of empirical, conceptual and historical analysis, this paper explores the rich moral background of the Yorùbás, among other cultures, as case study, and urges a return to the moral ideals that once dominated and characterized African states.
Bacterial Exopolysaccharides: Functionality and Prospects
Uchechukwu U. Nwodo,Ezekiel Green,Anthony I. Okoh
International Journal of Molecular Sciences , 2012, DOI: 10.3390/ijms131114002
Abstract: Diverse structural, functional and valuable polysaccharides are synthesized by bacteria of all taxa and secreted into the external environment. These polysaccharides are referred to as exopolysaccharides and they may either be homopolymeric or heteropolymeric in composition and of diverse high molecular weights (10 to 1000 kDa). The material properties of exopolysaccharides have revolutionized the industrial and medical sectors due to their retinue of functional applications and prospects. These applications have been extensive in areas such as pharmacological, nutraceutical, functional food, cosmeceutical, herbicides and insecticides among others, while prospects includes uses as anticoagulant, antithrombotic, immunomodulation, anticancer and as bioflocculants. Due to the extensive applications of bacterial exopolysaccharides, this overview provides basic information on their physiologic and morphologic functions as well as their applications and prospects in the medical and industrial sectors.
The Abanyole Dirge: “Escorting” the Dead with Song and Dance
Ezekiel Alembi
Folklore : Electronic Journal of Folklore , 2008,
Abstract: Song and dance pervades the life and the world of the Abanyole.When they are sad, they sing; when they are happy, they sing; when a child is born, they sing and dance and when one dies, they also sing and dance. So strong is the singing and dancing tradition in this community that it can be described as lubricating oil that the Abanyole use on their wheel of life as they transact different facets of their being. In this article, I examine the role of song and dance in a funeral context among the Abanyole of the Western Province of Kenya. The discussion is focused on traditional Abanyole songs. I make this distinction because Christian songs are also sung at funerals in Bunyore. Specifically, performances by individual mourners and night performances at funerals will be discussed, guided by the following questions: Who performs? When do the performances take place? What is the structure of the performance? What is the meaning of the performances within the funeral context? I have utilized the Infracultural Model in Folklore Analysis as the conceptual-analytical framework for this article. This model emphasises the interpretation of words and actions within specific cultural contexts. This essentially means that the meanings of the words and actions can only be located within the perceptions of the studied community. Underlying this model is a key concern that researchers should participate in the life of the communities, being a sound basis for learning, experiencing and documenting the beliefs, expectations, fears and perceptions of the communities studied.
The Calling and Work of Wellington Masatia Tambwa. A Traditional Healer From Bunyore, Kenya
Ezekiel Alembi
Folklore : Electronic Journal of Folklore , 2003,
Abstract: In this paper, I will introduce the work of one Kenyan healer, Mr. Wellington Masatia Tambwa. The paper is divided into two parts. The first part discusses the theme of healing and medicine in Africa and gives a short evaluative overview of the works of Edward E. Evans-Pritchard, Huges, John S. Mbiti, K. Thairu and Raimo Harjula. The purpose of this discussion is to show the gap which, I argue, should be filled by scholars interested in this theme in Africa. The second part of this paper discusses the work of Masatia Tambwa. This contributes to fill the aforesaid gap. Empirical data for this paper comes from a number of people, whom I interviewed in Bunyore. It would be difficult to name all of them here, so I will name only a few: Joseph Osuka, Fronika Ayoti Osuka and John Irili. Discussions with these people offered me a good opportunity to learn about the healer Masatia Tambwa and his background. Much information concerning the medicine man came from discussions with Masatia himself.
