The international politics of famine relief operations in Ethiopia: A case study of the 1984-86 famine relief operations.
No full textThis thesis is a study of the international relief assistance to Ethiopia during the 1984-86 famine. It begins by examining the country's glorious past vis-a-vis its present international status. In Part One, the underlying causes of the famine are discussed to provide a background to the subsequent analysis of the international relief effort. Also discussed, is the role of the international media in alerting public opinion and successfully transforming the famine into an issue of international concern. In Part Two, the responses of the various actors are analysed: in particular the bilateral response of Ethiopia's political allies and her opponents; of the Western non-governmental organizations (NGOs) and the role of the United Nations in coordinating the international relief effort at the multilateral level. Part Three (Chapter Eight), tests the theoretical assumptions outlined at the beginning of the thesis. With regard to the first, namely the relative importance of opponents and allies, the study concludes Ethiopia's political opponents were more responsive to her appeal for emergency relief than her allies. With regard to the second, namely the role of the NGOs the conclusion is that these organizations played the most important role in shaping the international response to the emergency. Chapter Nine summarizes our general conclusions
NEXUS BETWEEN POINT OF SALE, AUTOMATED TELLER MACHINE, MOBILE BANKING AND CURRENCY IN CIRCULATION IN NIGERIA: ARDL BOND TEST COINTEGRATION APPROACH
No full textThis paper examines the nexus between point of sale (POS), automated teller machine (ATM), mobile banking (MBK) and currency in circulation in Nigeria. Quarterly data were sourced from Central Bank of Nigeria from January 2009- September 2020. Unit root, ARDL bond test cointegration were employed as techniques of analysis. The findings reveal that, there is significant and long run relationship between the ATM, POS MBK and currency in circulation. ARDL bound test cointegration shows that, there exists a long run cointegrating relationship between the variables under investigation. The estimated coefficient of the error correction term suggests that the system (economy) may correct its previous period disequilibrium by about 49% annually. The paper recommended that Government through the CBN should formulate and improve monetarypolicies (cashless policy) aimed at encouraging and improving E-payment system in order to actualize the objective of cashless policy in Nigeria. Also Government, monetary authorities (CBN, Ministry of finance,) and commercial banks should educate and enlighten the people on the Advantages of using POS, MBK, ATM and CCHEQ in their day to day activities in Nigeria in other to reduce currency in circulation and improve economic performance
EFFECT OF E-PAYMENTS ON PERFORMANCE OF COMMERCIAL ACTIVITIES IN YOLA METROPOLIS OF ADAMAWA STATE
No full textThe study examined the effect of e-payments on performance of commercial activities in Yola metropolis, Adamawa state. Primary data were sourced via the administration of 373 structured questionnaires designed in five Likert scale format out of which 325 were return for analysis. The study covered the period from 2019 to 2020. Structural Equation Modeling (SEM) was employed in identifying the effect of E-payment product (point of sale (POS), mobile banking and challenges of E-payments on the performance of commercial activities) in Yola metropolis of Adamawa state. The data was normally distributed as indicated by confirmatory factor analysis and normality test. The coefficient of mobile banking and point of sale (POS), are positively related to performance of commercial activities. This implies that a unit increase in mobile banking transaction increases the performance of commercial activities in Yola metropolis by 0.433 units. Also one unit increase in point of sale transaction will increase the performance of commercial activities in Yola metropolis by 0.454 units. On the other hand there is negative relationship between performance of commercial activities in Yola metropolis and challenges of e-payments in Yola metropolis. This implies that one unit increase in challenges of e-payments transaction will decrease the performance of commercial activities in Yola metropolis by -.121units. Moreover, the coefficient of mobile banking, point of sale and challenges of e-payments are found to be statistically significant at 1 per cent. Hence, the null hypothesis was rejected. The study recommends that Government and relevant authorities should formulate monetary policies aimed at encouraging and improved E-payment system so as to actualize the objective of E[1]payment system in adamawa state and Nigeria
Enhancement of transition metal-based supercapacitor materials for improved performance
No full textIn this research work, metal-doped MoS2 of Cobalt and Manganese (Co-MoS2 and Mn-MoS2) nanocomposites of different ratios of dopant concentrations were synthesized with a facile hydrothermal technique. The samples were characterized using various instruments to elucidate the properties and novelties of the prepared nanomaterials and likewise to establish their supercapacitive suitability for energy storage devices.
The bibliometric evaluation of the development of literary works involving supercapacitor devices since the use of MoS2 as the active materials in energy storage (Supercapacitor) was performed. The bibliometric analysis of the studied materials gives us perspectives on the strengths and weaknesses of the materials, which enable us to identify the area of focus and the targeted publication outlets.
The Co-MoS2 electrode materials (CMS1 and CMS3) were electrochemically evaluated for their energy storage performance, the materials exhibit specific capacitances of 164 and 146 Fg-1 at 1 Ag-1 for the working electrodes, respectively. Also, the energy densities of 3.67 and 2.05 Wh/kg with power densities of 3279.97 and 2960.26 W/kg were calculated for both electrode materials, respectively. While the electrochemical performance of the Mn-doped MoS2 electrode material showed a pseudo-capacitive behavior, with a specific capacitance of 70.37 Fg−1, and with a corresponding energy density of 3.14 Whkg−1 and a power density of 4346.35 Wkg−1. The general obtained results show that the electrode materials were well prepared and the enhancement of MoS2 properties is achievable with the transition metal composites. These improved properties of MoS2 composites showing the suitability of the nanomaterials for the energy storage applications have been explained in this work with possible future works recommended in the report.D.

Age-dependent alteration of antioxidant defense system in hypertensive and type-2 diabetes patients
No full textBACKGROUND: The association between hypertension and diabetes has been linked to increased oxidative stress with age. This study was to examine the level of age-dependent alterations in antioxidant defense system between patients having hypertension and/or type-2 diabetes. METHODS: The study was conducted at the Ahmadu Bello University Teaching Hospital, Zaria-Nigeria, using 200 Subjects recruited from the cardiology, endocrinology and outpatient clinics. They were divided into four groups of 50 subjects each, namely: Diabetic group (DG), hypertensive (HG) and hypertensive-diabetic group (HDG) as cases. The control group (CG) was non-diabetic normotensive subjects. They were all stratified into six age-ranges namely 20-29, 30-39, 40-49, 50-59, 60-69, 70-79 years. Oxidative stress markers (lipid peroxidation, antioxidant vitamins and elements, enzymatic and non-enzymatic antioxidant) were measured in the blood sample collected from all subjects in each age group within the study groups. RESULTS: The results in the DG, HG and HDG, showed that the percentage decrease in enzymatic antioxidants and antioxidant vitamins with age were significantly (P <0.05) higher than 10.8 and 20.0 respectively when compared to the CG, whereas, the level of decrease in serum Selenium at same age range was significantly higher than 52.8 . The level of lipid peroxidation in the cases was observed to be significantly (P <0.05) higher than 89.9 when compared to the mean reference values (2.94 +/- 0.05 nmol/ml) of the CG at same age range. Also, the decrease levels of endogenous antioxidants were observed to be directly related to aging. CONCLUSION: The result obtained demonstrates the percentage age-dependent alteration in oxidative stress markers. The percentage decrease in the antioxidant levels during aging could be an explanation to the possible link, underlying the complication of type-2 diabetes and hypertension in this locale. Hence, antioxidants supplements may be useful in the management of the diseases during aging
LIBRARIANS’ PERCEPTION ON THE USE OF SOCIAL MEDIA AS A TOOL FOR INFORMATION SERVICE PROVISION IN KASHIM IBRAHIM LIBRARY, AHMADU BELLO UNIVERSITY, ZARIA, NIGERIA
No full textSocial media have become an indispensable and current trend of communication in the modern era today, as a result of this, academic libraries adopt social media such as Facebook, X (formally Twitter), YouTube, and Flickr for effective and efficient information services provision in the 21st century. The study investigates the librarians’ perception on the use of social media (SM) as a tool for information service provision in Kashim Ibrahim Library, Ahmadu Bello University, Zaria. A total number of 91 copies of the questionnaire were administered to the respondents and a total of 85 were returned and found useful for the study. All data were categorized and analysed using tables, frequency, and simple percentage were used to analyse the data. Findings revealed that SM are used to render various library services. However, the major challenges faced by the academic library staff when using SM for information services provision include inadequate power supply, inadequate bandwidth, security privacy and copyright issues, high cost of Internet services. The study recommended that the academic librarians should be encouraged in the use of SM to develop their skills in information services provision
The Nigerian Enterprises Promotion Decrees (1972 and 1977) and indigenisation in Nigeria
No full textThe thesis is a comprehensive examination of the Nigerian
Enterprises Promotion Decrees of 1972 and 1977, and more broadly
of the process of indigenisation in Nigeria.
A brief introduction to the historical background of indigenisation
before 1970 is followed by an account of the timing of the Decrees
in the context of the oil boom in the country's economy. An
examination of the problems encountered in implementing the Decrees
and their effects, and an analysis of the distribution of benefits,
is informed by empirical research including interviews, carried out
by the author in Nigeria between 1982 and 1985.
The record shows that indigenisation has led to the consolidation
of an economy which accommodates the interests of ex-State personnel,
the State as an institution, private indigenous businessmen and
foreign capital, in an order which is far from certain to bring about
the national economic independence which, in official terms, is the
chief objective.
Nigeria's commitment to capitalism and the promotion of
Indigenous private enterprise, on the basis of resources generated
initially by the agricultural economy, between the 1940s and 1960s,
and then much more spectacularly and more significantly by oil
revenues in the 1970s, provides an instructive example of the limits
to what a post-colonial society in black Africa can achieve by trying
to indigenise the ownership structure of its economy
