Abstract: This paper presents insights and perceptions of stakeholders involved in the development and implementation of residential smart grid pilot projects in the Netherlands, adding to the limited information that is currently available in this area, while expectations about the potential benefits of smart grids are high. The main research questions of this study are: (1) How have some typical residential smart grid pilots in the Netherlands been set up? (2) Which stakeholders are involved in these pilots in the year 2014? (3) What are their views and perceptions with regards to the development and performance of residential smart grids? and (4) What do these stakeholders think about the products and services that may support an active participation of end-users in a smart energy home? To obtain information, we evaluated five residential smart grid pilot projects where smart energy products and services have been implemented. Semi-structured interviews were conducted with nine stakeholders involved in these projects. The Strategic Niche management framework was used to identify the present state of development and implementation of smart grid pilots. Our study shows that in the Netherlands residential smart grid pilots have been set-up and funded mainly by the government and grid operators. Other stakeholders involved include energy suppliers, end-users (as an energy cooperative or individual household), product and service suppliers, Information and Communication Technology (ICT) companies, and knowledge institutes. Currently a technology-push approach exists which barely includes an integrated approach towards smart grids products and services development. To the opinion of the interviewed stakeholders, current products and services offered in residential smart grid pilots are functionally attractive, but often too technically complex for the understanding of end-users. Hence, the general view held by respondents is that end-users should be the starting point in the development of smart grid products and services at the residential areas.
Investigation of plasmid DNA and antibiotic resistance in some pathogenic organisms
NE Uchechi, K Erinma
African Journal of Biotechnology , 2007,
Abstract: Twenty-eight strains of Salmonella, Pseudomonas, and Escherichia coli isolated from cultures of stool, urine and wound were tested for their susceptibility to various antimicrobial agents. All the strains were resistant to erythromycin and tetracycline. Nineteen Salmonella isolates were susceptible to chloramphenicol and gentamycin. All the Pseudomonas and Escherichia coli isolates were resistant to chloramphenicol and cloxacillin while one Pseudomonas species and three Escherichia coli isolates were sensitive to gentamycin. The antibiotic resistance determinants in each strain were encoded by plasmid. These isolates were typed by plasmid profile analysis according to their different molecular weights. Several similar and distinct profiles were identified for most resistant and sensitive isolates. It appeared that a single strain containing a plasmid conferring multiple drug resistance emerged within the bacterial population and was able to adapt and to survive the challenges of antibiotics as they were introduced into clinical medicine. Therefore, the acquisition of plasmid has greatly contributed to the rapid spread of antibiotic resistance genes in the bacterial population.

Abstract: The purposes of this paper was to propose and discuss benchmarking as managerial tool to develop the capacity of higher education institutions in Nigeria as to evaluate themselves at all levels and functions .There has also been considered as an effort to develop and apply performance indicators as aid to good management in the institutions.The paper concluded that higher education institutions should begin to benchmark theiractivities against those institutions that considered best-in- class in their operations in order to drive continuous quality improvement in efficiency in the face of dramatic fall in public funding per student. The paper established some of the benefits institutions can derive from benchmarking themselves, such as sharing of knowledge, improvement of institutional quality, exposition of people to new ideas, broadening of the institutions’ operating perspectives, creating of a culture of being open to new ideas, serving as a catalyst for learning etc. The paper established benchmarking to be a potential vehicle to evolve, perhaps leading to a more innovative Nigeria University management in future.The position taken in this paper is that benchmarking should be undertaken by higher education in the country so as to learn from each other’s best practices.

Abstract: Hypertension is a major public health problem. Due to paucity of data, the burden of hypertension in Nigeria might be underestimated. Estimating the prevalence of hypertension in populations of Nigeria would be useful in efforts to control hypertension and prevent its consequences. This survey aimed to assess the prevalence, detection, treatment and control of hypertension in Nsukka, a city located in South-Eastern Nigeria. Hypertension prevalence, awareness, treatment, and control (outcomes) were examined in 756 adult participants (364 men and 392 women) aged 18 years and above. Blood pressure (BP) of the participants was measured and they also answered a detailed questionnaire. Hypertension was defined as BP ≥ 140 for systolic BP and or ≥ 90 mm Hg for diastolic BP or being on antihypertensive therapy. Prevalence of hypertension was 21.1%. Men had higher prevalence of high BP compared to women. Systolic and diastolic BP increased with age in both men and women. Detection of high BP in participants with raised blood pressure was 40.3% and 24.7% for males and females respectively. Only 23.7% and 17.5% of males and females respectively with high BP were on antihypertensive treatment while 5.0% of males and 17.5% of females with hypertension were controlled. Prevalence of hypertension was comparable with other studies in Nigeria and Africa. The results showed a poor detection, treatment and control of hypertension. This underscores the need for comprehensive evaluation of the prevalence of hypertension and other cardiovascular diseases in Nigeria.
Comparison of the spatial and temporal variability of drought indices in Somalia and Lake Chad Basin

African Journal of Environmental Science and Technology , 2011,
Abstract: The science and dynamics underlying drought is complex, yet understandable if approached carefully using scientific method. In this paper, scientific perspective was applied to explain and compare drought indices in Somalia and Lake Chad Basin (LCB). Geographic information system (GIS) was used to analyze similarities and differences of locational attributes of temporal and spatial drought data in both regions. There was a similarity in the thirty-year annual precipitation, aridity index and spatial distribution of surface water bodies. Net primary production (NPP) was around -10 g carbon per square meter per year (gcm-2yr-1) in south of Somalia and -20 gcm-2yr-1 in the north in 2007. In 2009, the NPP dropped sharply to near -80 gcm-2yr-1everywhere in the Somalia. In contrast, NPP has been increasing gradually in LCB from -10 gcm-2yr-1 in 2007 to near 100 gcm-2yr-1 in 2010. Standard precipitation index (SPI) analysis indicates increase in SPI value from 0 (near normal) in 2009 to around 1.3 (moderately wet) in 2010 in LCB. In Somalia however, there was a corresponding decrease from 0 to -2 (extremely dry). Continued decrease in precipitation southwards in Somalia appears to have triggered the present drought. The threat of drought in LCB has not been given adequate coverage partly because the Sahel region today may have been receiving just enough precipitation. The lessons from the current drought in Horn of Africa are however, a reminder of the potential threat facing over 30 million inhabitants of LCB.
Interest Rate Liberalization, Financial Development and Economic Growth in Nigeria (1970-2008)

Asian Social Science , 2012, DOI: 10.5539/ass.v8n3p292
Abstract: This paper presents a framework of analysis for examining the impact of changes in interest rate policy and financial reforms on economic growth. Using annual dataset for Nigeria for the period covering 1970 to 2008, our results are three-folds. Firstly, deposit rate of interest has a positive effect on financial depth. Secondly, the multivariate granger causality tests reveal that there is only one-way causality between financial depth and economic growth; the flow running from financial depth to economic growth. Finally, interest rate liberalization tends to granger cause financial depth and economic growth. This enquiry therefore suggests that a departure from rigidly fixed deposit rate of interest will enhance financial depth and improve the country’s rate of economic growth. The current financial reforms should be directed at achieving a more liberal deposit rate of interest.

Abstract: Three microorganisms causing gastroenteritis were used for the study of the antibacterial effects of Phyllantus niruri, extracts. The bacterial pathogens used were Escherichia coli, Staphylococcus aureus and Salmonella typhi. The solvents used for the extraction of active components of the plant (whole plant) were hot water, cold water (both as aqueous solvent) and ethanol. The antibacterial effect of the plant extracts showed that all the extracts were inhibitory to E. coli, S. aureus and S. typhi. The results of the Minimum Inhibitory Concentration (MIC) value of the extracts on the organisms are 31.25 mg mL for S. aureus, 15.625 mg mL for E. coli and 31.25-62.50 mg mL for S. typhi. !The pathogens used were not multi-drug resistant strains to most of the orthodox drugs. The antibacterial effect of plant extracts of P. niruri tends to give a clue to the problem of drug resistant strains of microorganisms causing gastroenteristis and thus provides the possibility of drug development for such human diseases.
Hofstede’s ‘Software of the Mind’ Revisited and Tested: The Case of Cadbury Worldwide and Cadbury (Nigeria) Plc - A Qualitative Study

Abstract: Hofstede (1980, 2001) contributed in no small way to the impact of national culture on management practices as he demonstrated the importance of culture on relationships at work which could also be used to account for the productivity of workers in the workplaces. This cannot come at a better time than when it did, as globalisation, multinationalisation and internalisation are now the order of the day. The effect of this is more pronounced in the mobility of labour as people move from one geographical and cultural area to another in search of jobs and investments. These movements obviously imply ‘moving’ with their national cultures which Hofstede (1980, 2001:1) referred to as ‘the software of the mind’. He (2001:1) went further to warn that this ‘software of the mind’ is difficult to ‘unlearn’. This paper is a qualitative study based on exploratory semi-structured interviews conducted on100 participants to create a better understanding of their experiences in their organisations. The study concludes that the ‘unlearning’ processes are more difficult than the ‘learning’ processes which demonstrate that culture is enduring in line with the findings of Hofstede (1980, 2001).
Theorising the Concept of Organisational Artefacts: How It Enhances the Development of Corporate/Organisational Identity
Olusoji James George,Oluwakemi Owoyemi,Uchechi Onakala
International Journal of Business Administration , 2012, DOI: 10.5430/ijba.v3n4p37
Abstract: Organisational artefacts are materials, buildings, symbols, names, images, logos, catchwords that make sense to all the stakeholders of an organisation; they therefore have meanings and do not just exist. Artefacts demonstrate the culture, norms and values of those who are in the organisation as well as all its stakeholders. In a nutshell it is a medium of communication within the members of the organisation and those outside the organisation; it makes enormous statements. This paper employing the descriptive/historical approach will examine the impacts of organisational artefacts on business organisations including how it helps in the development of a corporate identity in the organisations. This is more so as an organisation’s identity –expressed partly through organisational artefacts- goes directly to the heart of the existence of the organisation. The study concludes that directly and indirectly, knowingly and unknowingly, organisational artefacts enhance the development of corporate identity.
Enhancing Employee Performance in Nigeria Through Efficient Time Management Frameworks
IGBOKWE-IBETO,EGBON Uchechi,Chinyeaka Justine
Asian Economic and Financial Review , 2012,
Abstract: In developing countries like Nigeria, the need for time management in organizations cannot be over emphasized. Time management helps in achieving individual and organizational goals in view of the limited amount of time available to man. The paper examines and analyses how time abundant yet scarce resources can be managed for effective and efficient employee performance. In analyzing the issues raised in the paper, we applied time management theories and approaches which enable us direct our search light on the techniques and processes of time management, as well as, the relationship between managers and subordinates as regards time management. The study revealed that organizational managers and subordinates are faced with time management problems which have created difficulties for the attainment of organizational goals. However, certain steps have to be taken to inculcate and promote the virtue of time management that can lead to employee effectiveness and efficiency in the work place. Among others, subordinates in an organization should be encouraged to ask questions and seek agreements on priorities, be prepared to compromise, if necessary in order to make the best use of time, be on guard against unscheduled visitors and telephone calls. Also meetings should be held during specific hours of the day. During other times, people should be available for regular duties at their work-places. These recommendations should be sustained overtime and should be seen as a way of life in organizations. It concludes that time an important element in organizational life, if properly managed would ensure organizational productivity and development.
