Pan-Atlantic University is a private, non-profit educational institution in Lagos, Nigeria. The university had its origin as the Lagos Business School , established in 1991. The federal government approved the university as Pan-African University in 2002, and the LBS became its first school. In May 2013 its name was changed to Pan-Atlantic University, in order to avoid confusion with the Pan-African University of the African Union. The Ajah Campus was completed in 2003 and in 2010 work began on the Ibeju-Lekki campus.In September 2011 the university launched the Virtual Museum of Modern Nigerian Art, a website created by Jess Castellote, a Spanish architect that includes over 400 works from 81 artists, including pioneering Nigerian artists such as Aina Onabolu and Bruce Onobrakpeya and emerging artists such as Richardson Ovbiebo and Babalola Lawson.The University's Enterprise Development Centre works with the Small and Medium Enterprise Department of the International Finance Corporation to provide the SME Toolkit Nigeria.This gives small businesses free business management information and training.In November and December 2011 the EDC organized a "Global Entrepreneurship Week", with a series of events in Lagos. Many Nigerians have ambitions to start a business, and the conference was extremely well-attended.In July 2011 British Prime Minister David Cameron spoke at the Pan-Atlantic University in Lagos, discussing aid, trade and democracy. He spoke in favor of an African free trade area, and of increased trade with Britain.On 17 November 2014 the University launched its first ever undergraduate programmes in its new campus at Ibeju-Lekki.

In massive MIMO technology the channel is estimated using uplink training by sending an orthogonal pilot sequence from users to the base station. These sequences are re-used in the cell and also outside the cell. This gives rise to a channel estimation error referred to as pilot contamination. Large scale fading precoding which is based on the cooperation between cells has been proposed to mitigate pilot contamination. However this approach is known to limit in data transmission rate. In this paper, we propose a novel uplink training scheme to mitigate pilot contamination using a large scale fading precoding without the need of cooperation between cells. This achieves a higher transmission rate over existing method. The simulation results show that the proposed scheme improves 5% outage rate 10 times, over the existing method. © Springer International Publishing AG 2017.

The geochemistry of a coastal aquifer was assessed using statistical and geospatial analysis tools for the pre-monsoon, rainy and post-monsoon seasons. Data were obtained from both the field and laboratory analysis of water samples. Statistical methods such as correlation coefficients, piper plots, factor analysis and mixing index were used to gain insights into the geochemistry, while geospatial tools were used to create contours to understand the spatial distribution of the measured groundwater parameters of the coastal aquifer. The measured groundwater levels ranged from −0.84 to 30.08 m above mean sea level. The Electrical Conductivities and Total Dissolved Solids values were observed to have perfectly correlated with each other. Groundwater salinities were generally high, as over 94% of the water samples tested exceeded the WHO drinking water limit of 750 µS/cm and 500 mg/l, respectively. The groundwater pH was generally slightly alkaline but could be slightly acidic in the rainy season. The Na+, K+, Mg2+, Cl− and SO4 2− were observed to have high impacts on the geochemistry and also had tendencies to form similar trends. EC, TDS and NaCl values above 1000 mg/l in the groundwater were observed to generally skew towards the ocean during the rainy season. The principal process influencing the geochemistry was found to be seawater intrusion, while mineral dissolutions and rainwater percolation play lesser roles. The aquifer predominantly comprises Na–Cl waters of marine origin. The study shows the growing importance and applicability of integrated statistical and geospatial approaches for better understanding of groundwater and geochemistry of aquifers. © 2017, The Author(s).

Different variants of optical orthogonal frequency divisions multiplexing (O-OFDM) have been proposed for intensity modulation/direct detection (IM/DD) based indoor optical wireless communication. Among those schemes, direct current biased optical OFDM (DCO-OFDM) and asymmetrically clipped optical OFDM (ACO-OFDM) are widely adopted variants. These schemes have either reduced spectral or power efficiencies, but the co-existence of both good spectral and power efficiency is vital to tackle the challenge of limited bandwidth and limited optical power constraint scenarios. In this paper, simultaneous transmission of Multiple ACO-OFDM frames on both even and odd subcarriers has been proposed to achieve better spectral and energy efficiencies. The analysis of the theoretical bit error rate (BER) performance of the proposed scheme has been done and compared with the result from Monte Carlo simulation for Additive white Gaussian noise (AWGN) channel environment. A good agreement has been achieved between the theoretical BER bound and the simulated BER from Monte Carlo simulation. The proposed scheme provides better spectral efficiency (SE) compared to ACO-OFDM and equivalent SE compared to DCO-OFDM. In addition, it has shown superior energy efficiency performance than both ACO-OFDM and DCO-OFDM of equal SE. © 2017 Journal of Communications.

We propose and analyse a nonlinear mathematical model for the transmission dynamics of pneumonia disease in a population of varying size. The deterministic compartmental model is studied using stability theory of differential equations. The effective reproduction number is obtained and also the asymptotic stability conditions for the disease free and as well as for the endemic equilibria are established. The possibility of bifurcation of the model and the sensitivity indices of the basic reproduction number to the key parameters are determined. Using Pontryagin's maximum principle, the optimal control problem is formulated with three control strategies: namely disease prevention through education, treatment and screening. The cost-effectiveness analysis of the adopted control strategies revealed that the combination of prevention and treatment is the most cost-effective intervention strategies to combat the pneumonia pandemic. Numerical simulation is performed and pertinent results are displayed graphically. © 2017 The Author(s). Published by Informa UK Limited, trading as Taylor & Francis Group.

Objective: To determine the phytochemical composition, antioxidant and anticancer activities of ethanolic and water leaves extracts of Annona muricata (A. muricata) from the Eastern Uganda. Methods: Phytochemical screening was conducted using standard qualitative methods and a Chi-square goodness of fit test was used to assign the relative abundance of the different phytochemicals. The antioxidant activity was determined using the 2, 2-diphenyl-2-picrylhydrazyl and reducing power methods whereas the in vitro anticancer activity was determined using three different cell lines. Results: Phytochemical screening of the extracts revealed that they were rich in secondary class metabolite compounds such as alkaloids, saponins, terpenoids, flavonoids, coumarins and lactones, anthraquinones, tannins, cardiac glycosides, phenols and phytosterols. Total phenolics in the water extract were (683.69±0.09) μg/mL gallic acid equivalents (GAE) while it was (372.92±0.15) μg/mL GAE in the ethanolic extract. The reducing power was 216.41 μg/mL in the water extract and 470.51 μg/mL GAE in the ethanolic extract. In vitro antioxidant activity IC50 was 2.0456 mg/mL and 0.9077 mg/mL for ethanolic and water leaves extracts of A. muricata respectively. The ethanolic leaves extract was found to be selectively cytotoxic in vitro to tumor cell lines (EACC, MDA and SKBR3) with IC50 values of 335.85 μg/mL, 248.77 μg/mL, 202.33 μg/mL respectively, while it had no cytotoxic effect on normal spleen cells. The data also showed that water leaves extract of A. muricata had no anticancer effect at all tested concentrations. Conclusions: The results showed that A. muricata was a promising new antioxidant and anticancer agent. © 2014 Hainan Medical College.

Purpose - The authors aim to develop and test hypotheses that link outsourcing and subcontracting-in activities of small high-tech firms to their radical innovativeness. In addition, they seek to investigate how a firm's strategy moderates the associations between their outsourcing and subcontracting-in activities and radical innovativeness. Design/methodology/ approach - The authors utilized regression analytical technique and categorical moderation analytical technique to test their hypotheses on survey data of 579 firms. Findings - Results show that outsourcing has a positive association with radical innovativeness. In contrast, subcontracting-in shows a negative association with radical innovativeness. Finally, the influence of both outsourcing and subcontracting-in activities on radical innovativeness are contingent upon a firm's manufacturing strategy. Research limitations/ implications - There are potential limitations relating to the authors' use of secondary data. There is a need to investigate the processes through which outsourcing and subcontracting-in relate to innovation performance. Practical implications - An implication of this study is that in order to develop radical innovativeness, firms need to consider their strategic or competitive inclination when evaluating their outsourcing and subcontracting-in decisions and activities. Social implications - There are also social implications since outsourcing and subcontracting-in activities involve social relationships. Originality/value - Linking boundary spanning activities of firms to innovation performance represents a contribution to the literature. Further, establishing that the effectiveness of such boundary activities depends on a firm's specific manufacturing strategy represents a contribution. © 2013 Emerald Group Publishing Limited.

BACKGROUND: Malaria is caused by five Plasmodium species and transmitted by anopheline mosquitoes. It occurs in single and mixed infections. Mixed infection easily leads to misdiagnosis. Accurate detection of malaria species is vital. Therefore, the study was conducted to determine the level of mixed infection and misdiagnosis of malaria species in the study area using SYBR Green I-based real time PCR.METHODS: The study was conducted in seven health centres from North Gondar, north-west Ethiopia. The data of all febrile patients, who attended the outpatient department for malaria diagnosis, from October to December 2013, was recorded. Dried blood spots were prepared from 168 positive samples for molecular re-evaluation. Parasite DNA was extracted using a commercial kit and Plasmodium species were re-evaluated with SYBR Green I-based real time PCR to detect mixed infections and misdiagnosed mono-infections.RESULTS: Among 7343 patients who were diagnosed for malaria in six study sites within the second quarter of the Ethiopian fiscal year (2013) 1802 (24.54%) were positive for malaria parasite. Out of this, 1,216 (67.48%) Plasmodium falciparum, 553 (30.68%) Plasmodium vivax and 33 (1.8%) mixed infections of both species were recorded. The result showed high prevalence of P. falciparum and P. vivax, but very low prevalence of mixed infections. Among 168 samples collected on dried blood spot 7 (4.17%) were P. vivax, 158 (94.05%) were P. falciparum and 3 (1.80%) were mixed infections of both species. After re-evaluation 10 (5.95%) P. vivax, 112 (66.67%) P. falciparum, 21 (12.50%) P. falciparum + P. vivax mixed infection, and 17 (10.12%) Plasmodium ovale positive rate was recorded. The re-evaluation showed high level of mixed infection, and misdiagnosis of P. ovale and P. vivax.CONCLUSIONS: The result shows that P. falciparum prevalence is higher than P. vivax in the study area. The results, obtained from SYBR Green I-based real time PCR, indicated that the diagnosis efficiency of microscopy is very low for species-specific and mixed infection detection. Therefore, real time PCR-based species diagnosis should be applied for clinical diagnosis and quality control purposes in order to prevent the advent of drug resistant strains due to misdiagnosis and mistreatment.

The purpose of this study was to investigate the awareness, usage, perceived effectiveness and potential future use of improvement tools and techniques via two sets of comparisons: between public and private sector organisations, and between manufacturers and service organisations. The need for the study was driven by the current lack of understanding of the extent of improvement tools and techniques adoption on a global scale. A questionnaire survey of 453 respondents from over 20 countries was conducted and the quantitative data were analysed through use of the IBM SPSS software package. The studys findings indicated that there are no significant differences between both sets of organisations for the majority of improvement tools and techniques. However, this study has shown that public sector organisations are more likely to adopt some improvement tools and techniques in comparison to their private sector counterparts. Similarly, service organisations are also more likely to adopt some improvement tools and techniques than their manufacturing counterparts. These results contradict the conventional perception that improvement tools and techniques are used more often by the private sector and manufacturing organisations. © 2014 Taylor & Francis.

Scholars of organisational behaviour have opined that the culture of a work organisation is nothing, but a mere derivative or microcosm of the wider national culture. Nevertheless, in this present article, an anti-thesis of the current thinking has been providedby the development of a conceptual model of cultural change for African indigenous organisations. Based on the application of the modernisation theory of cultural change; the model presented a justification for the import of the current spate of globalisation which necessitates that for indigenous work organisations (especially business enterprises) resident in Africa to become globally competitive they must disengage from traditional beliefs and values that are inimical to business performance. This revolutionary shift would help them proactively evoke cultures that are completely different from those of the nations in which they are domestically domiciled; and possibly change the beliefs and values of organisational workers from those that constitute the various cultures of their respective African states. Consequently, a displacement of the existing paradigm in the literature of organisational/national culture interface which refutes the possibility of organisational culture transcending the boundaries of national culture becomes inevitable. ©2011 Inderscience Enterprises Ltd.

Maternal mortality remains a major global public health concern despite many international efforts. Facility-based childbirth increases access to appropriate skilled attendance and emergency obstetric care services as the vast majority of obstetric complications occur during delivery. The purpose of the study was to determine the proportion of facility delivery and assess factors influencing utilization of health facility for childbirth.A cross-sectional study was conducted in two rural districts of Hadiya zone, southern Ethiopia. Participants who delivered within three years of the survey were selected by stratified random sampling. Trained interviewers administered a pre-tested semi-structured questionnaire. We employed bivariate analysis and logistic regression to identify determinants of facility-based delivery.Data from 751 participants showed that 26.9% of deliveries were attended in health facilities. In bivariate analysis, maternal age, education, husbands level of education, possession of radio, antenatal care, place of recent ANC attended, planned pregnancy, wealth quintile, parity, birth preparedness and complication readiness, being a model family and distance from the nearest health facility were associated with facility delivery. On multiple logistic regression, age, educational status, antenatal care, distance from the nearest health facility, wealth quintile, being a model family, planned pregnancy and place of recent ANC attended were the determinants of facility-based childbirth.Efforts to improve institutional deliveries in the region must strengthen initiatives that promote female education, opportunities for wealth creation, female empowerment and increased uptake of family planning among others. Service related barriers and cultural influences on the use of health facility for childbirth require further evaluation.
