One of the developments in the African Union (AU) is the recognition and reconnection of Africans in the Diasporas through policy formulations and other affirmative programmes. The aim is to ensure that Africans wherever they are located can reconnect with their roots and have a true sense of identity as Africans. This is a laudable achievement on the part of AU and the entire Africans in the Diaspora. While programmes and activities aimed at bridging this gap are being fashioned out by both parties, one of the major issues that must not be ignored is the inclusion of youth in these activities. Consequently, the questions are: what is the place of youth in AU-Diaspora relations? What are the structures put in place whether at the institutional or at the Diaspora levels in ensuring that youth have a voice in the ongoing bonding process between the two parties? Providing answer to these questions in this article become pertinent at this early stage in order to carry the young ones, the future of tomorrow along in the scheme of things regarding AU and Africans in the Diaspora. © 2017, IGI Global.

Purpose: The purpose of this paper is to examine the dynamics of food insufficiency and its determinants among farming households in Southwestern Nigeria. Design/methodology/approach: A combination of cluster and systematic random sampling was used to select 40 households in each local government area of the selected two states. This gives a total of 160 households per state and 320 households in all for the first data collection. Visiting the same households during the second data collection, only 150 households’ data were useful for analysis. Panel primary data were adopted and they were collected in two periods of late and early rain, respectively, over a period of nine months. Primary data were collected with the aid of a well-structured questionnaire, administered on farming households in the area of study. The needed information was collected through the use of interview schedules/questionnaires. Findings: The transition of food insufficiency households to food sufficiency indicated a differential of 4.25 percent, and the transition of food sufficiency to food insufficiency a differential of 9.33 percent. During the agricultural harvest season more households moved to food sufficiency status (16 percent), while off season insufficiency status was 25.3 percent. The probability of households escaping food insufficiency is 0.25, and the probability of households entering food insufficiency is 0.38. The study provides evidence of transient and high incidence of food insufficiency. Originality/value: Past studies of this nature only captured the food insufficiency status of households using a snapshot study. Hence, this study brought in innovation by examining the dynamics of food sufficiency/insufficiency in two periods. Therefore the question this study asks is: can a farm-household be food sufficient over a particular period of time and food insufficient in other time? © 2017, © Emerald Publishing Limited.

A generalized Schrödinger approximation, due to Ikhdair & Sever, of the semi-relativistic two-body problem with a rectangular barrier in (1+1) dimensions is compared with exact computations. Exact and approximate transmission and reflection coefficients are obtained in terms of local wave numbers. The approximate transmission and reflection coefficients turn out to be surprisingly accurate in an energy range | - V0| < 2μc2, where μ is the reduced mass, the scattering energy, and V0 the barrier top energy. The approximate wave numbers are less accurate. © 2016 Chinese Physical Society and IOP Publishing Ltd.

The Hulthén-type potential is perturbed by adding the Yukawa potential. By applying a short-range approximation to the Schrödinger equation containing this model via standard method, the scattering state solutions and the corresponding phase shifts were obtained. Our numerical calculations and graphical solutions show the dependencies of scattering phase shifts on Yukawa potential constant A, asymptotic wave number k, screening parameter α and angular momentum quantum number l. © 2016, Società Italiana di Fisica and Springer-Verlag Berlin Heidelberg.

In this paper, we studied the approximate scattering state solutions of the Dirac equation with the hyperbolical potential with pseudospin and spin symmetries. By applying an improved Greene-Aldrich approximation scheme within the formalism of functional analytical method, we obtained the spin-orbit quantum numbers dependent scattering phase shifts for the spin and pseudospin symmetries. The normalization constants, lower and upper radial spinor for the two symmetries, and the relativistic energy spectra were presented. Our results reveal that both the symmetry constants (Cps and Cs) and the spin-orbit quantum number affect scattering phase shifts significantly. © 2017 K. J. Oyewumi and O. J. Oluwadare.

Renewed interest has been established in the preparation of silicon nanoparticles for electronic device applications. In this work, we report on the production of silicon powders using a simple ball mill and of silicon nanocomposite ink for screen-printable photovoltaic device on a flexible substrate. Bulk single crystalline silicon was milled for 25 h in the ball mill. The structural properties of the produced silicon nanoparticles were investigated using X-ray diffraction (XRD) and transmission electron microscopy. The results show that the particles remained highly crystalline, though transformed from their original single crystalline state to polycrystalline. The elemental composition using energy dispersive X-ray florescence spectroscopy (EDXRF) revealed that contamination from iron (Fe) and chromium (Cr) of the milling media and oxygen from the atmosphere were insignificant. The size distribution of the nanoparticles follows a lognormal pattern that ranges from 60 nm to about 1.2 μm and a mean particle size of about 103 nm. Electrical characterization of screen-printed PN structures of the nanocomposite formed by embedding the powder into a suitable water-soluble polymer on Kapton sheet reveals an enhanced photocurrent transport resulting from photo-induced carrier generation in the depletion region with energy greater that the Schottky barrier height at the metal-composite interface. © 2017, Springer Science+Business Media Dordrecht.

This study examined hectarage and output responses of maize to market liberalization, price, price risk and financial support. The study covered a period of 40 years from 1970 to 2009. Secondary data were used. Data were analysed using descriptive statistics and multiple regressions. The descriptive statistics results showed that price ranged from USS 96.90 to 2039.37 per tonne and the price risk ranged from USS 444.71 to 740.78 per tonne. The descriptive statistics results showed that the output of maize ranged from 695.20 to 10959.00 tonnes, while the hectarage ranged from 700.40 to 3481.28 thousand hectare. Positive determinants of output and hectarage of maize include liberalization policy, maize price and the price risk. The sensitivity analysis showed that increase in price and price risk will continue to be major determinants of hectarage and output of maize. Government should continue to increase agricultural credit since they had positive impact on maize cultivation. © 2016 Trop. Agric. (Trinidad).

Journal of Poetry Therapy | Year: 2016
Commencing within the trajectory of perseverance, this paper sets out to examine the ways in which the phenomenon of waiting has been shrewdly explored by Niyi Osundare in Waiting Laughters [Osundare, N. (1990). Waiting laughters. Lagos: Malthouse]. Waiting is considered in the context of contemporary African literature and the poet’s own Yoruba tradition. It goes on to argue that the poet extends meanings of waiting far beyond their conventional limits, thus making it a complex, multi-levelled construct deployed as an instrument of resistance in the face of deplorable socio-economic and political conditions of contemporary African states. The paper identifies several manifestations of waiting: as patience, as natural progression, as social predicament, as historical inevitability, as humour, as laughter therapy, and as resistance. Each of these notions of waiting is an element of Osundare’s preoccupation with ways of overcoming the inequities, deprivations and injustices of African nations, and thus offers strategies for minimizing the effects of oppression. © 2016 The Author(s).

This research describes a complete fuel-level monitoring system. The research started with the design and construction of a fuel-level sensor and then was followed by configuration of a remote Aplicom 12 GSM module in order to interface the connected sensor. After the module configuration, monitoring of remote fuel is possible by sending control messages from a compatible mobile phone in order to query the status of the remote fuel sensor (and hence the volume of fuel in the tank). The status message from the module will be sent back via a Global System for Mobile Communications (GSM) network to the mobile phone that sent the query (or control) message. © 2014 Obikoya.
