Nigeria’s health status indicators have remained poor despite the country’s wealth in natural and human resources. National Strategic Health Development Plan 2009 to 2013 (NSHDP) affirmed that “the health status indicators for Nigeria are among the worst in the world and that on the average health status of the population has reduced, compared with the indicators of a decade earlier. Nigeria also has huge disparities in health status between geopolitical regions and income groups. One of the identified factors contributing to this challenge is poor funding; that is inability of the consumer to pay for healthcare services. This paper attempts to x-ray various means of financing health in Nigeria through desk research. Findings indicate that National Health Insurance Scheme has been effective means of bridging gap between have and have not in the country. The problem facing the scheme presently is low coverage, about one per cent of the entire population is currently covered. This paper therefore recommends among other things; expansion of the scheme to communities in the country. More awareness should be intensified on the individuals for funding as well, government should continue to subsidized health sector for the benefit of all the citizens.

The study is concern with the issues of entrepreneurship and its importance to economic development in Nigeria. These issues have pervaded the business / management discourse in recent times and are of particular importance to the less developed countries. Entrepreneurship lacks a common definition. It plays a strategic role in respect to economic development and consequently the study bears relevance to all aspects of economic and general development. The studythus attempts to undo these issues in alogical manner, for purposes of understanding the lexicon and its importance to a host of competing understanding and variables. By so doing it unpacks the very indirecttinges that permeate the thinking that border these issues.

The issue of Nigerian graduates’ unemployability and usability has long dominated the center of both practical and academic discussions in Nigeria. Stakeholder are very concerned that the current Nigerian graduates are unemployable as well as unusable by the firms in Nigeria due to the fact that they lack competencies and capabilities needed by those who sort for them. The paper examined several theories to build support on the need for training and development as the way out for developing Nigerian graduates for firms’ usability in the 21st century. Based on previous studies and relevant human developmental theories, the paper concludes that an effective training and development in the form of “master and apprentice formation method” would help Nigerian graduates to be usable by the firms in Nigeria. Therefore, the usability of Nigerian graduates would depend on their training and development (via master and apprentice formation method) they undergo after their higher education training. Finally, the paper offered suggestion for further studies.

The design of pleasant buildings that ensure physiological comfort of users is achieved through an understanding of the climate and the human responsive systems. Ibadan, South-West Nigeria falls within the warm-humid tropical climate characterized by periods of high rainfall, high humidity, solar radiation intensity with high temperature, light winds and long period of still air. Furthermore, it experiences the highest temperature of 34oC between the months of February and April with mean maximum indoor temperature of 32oC in most buildings with low indoor air velocity. Therefore, a study of residential buildings in Ibadan, Nigeria shows that most occupants of the buildings have persistent and growing problems of high indoor temperature due to the fact that most of the buildings are characterized by poor design in relation to the climate requiring a great deal of energy for cooling during climatic extremes. Other problems envisaging are poor natural ventilation, inadequate surface–volume ratio and poor building orientation leading to negative consequence that affect the occupant’s physiological comfort, capacity for mental and physical work, health and leisure. This paper therefore, identifies some Climate-response approaches (passive design) that can be adopted in this climatic region to minimize the use of energy for cooling, improving occupant’s comfort and enhancing low energy architecture. The aim is to reduce over-dependence on electricity demand and energy use in residential buildings while the result of the study shows that adopting certain passive design policies through appropriate selection of building materials, proper building orientation, adequate natural ventilation and application of some design elements can provide natural cooling and reduce the energy used for cooling in the buildings. The paper finally concludes that this will limit the energy demand for cooling and will also result in an adapted architecture to the south-west climatic environment thereby encouraging innovative design solutions for building professionals in a warm-humid tropical climate.

WASTE PICKING FROM LANDFILLS: SOURCES OF REVENUE FOR GOVERNMENT
OLOWOAKE, M. A. PhD

The increasing rate of unemployment of employable coupled with the high cost of living standard in any society could lead to people picking wastes from the Land fills to make end meet. Waste Pickers (Formal and informal) generate a costs of Revenue by picking wastes from Landfills. The paper sets to ensuring that, there are policies and enabling legislation giving adequate recognition to the due stake holders in sustainable waste management processes, provision of regular education on the symbiotic nature of the relationship among the stake holders (informal and formal waste pickers, intermediate market, waste processors, and the final end users. Data for the study were collected via the used mixed methods (qualitative and quantitative). And analysis carried out with the use of word count and ranking). The paper reveals that, high level of unemployment of employable Nigerians lead to waste picking by people, waste picking is hazardous to the informal pickers, and prefer doing the job because, it generates income for their livelihood. In Nigeria, waste picking is not confined to landfills but on the streets and living environments. Informal pickers realize little income, unlike the intermediaries (Formal pickers and processors) who sell directly to the Recyclers (End users). It is therefore recommended that, official authorities should recognize informal and formal pickers as critical stake holders in effective and sustainable waste management processes, creation of more landfills at the Local Government headquarters for the use of informal and formal waste pickers. Government should encourage people nearest to them for their waste, Activities of informal waste pickers at the ward level should be co-ordinate and regulated by official authorities via granting of permit also, the activities of the formal waste pickers should also be co-ordinate and regulated by Government via permit and legislation. In essence, the informal and formal waste pickers must operate via permit, likewise the recyclers (End users).(All the stakeholders, such as; Formal, informal waster pickers and recyclers should get Government permit).

Organizations cultural has recently received signiﬁcant attention from different scholars due to its vital role in the construction project’s failure or success. The global business is reflecting a throng of culture which warrant bringing into consistent adjustments in management of construction projects because of diversity of workforce in the construction industry. The study aim to identify the components of organizational culture in construction organization. A total of 162 survey questionnaires were distributed to 14 multinational construction organization and quantitative method of research was adopted. The factor’s loadings for the variables measures is significant and Cronbash Alpha factors of 0.941 is achieved. The ﬁndings reveal that Goal alignment and reliance, contractor commitment are the most signiﬁcant cultural component affecting project organization. Emporement orientation, worker orientation and cooperative orientation contribute to improved overall performance and participant satisfaction. Professionals in construction industry can use the finding in implementing practices that can influenc the sustainability and achievement of construction projects.

The study examined the causal relationship between money supply growth and inflation in Nigeria using time series data for the period of thirty-three (32) years. In analyzing the data both ordinary least square (OLS) regression method and granger causality test were employed. Variables for this study are (inflation, money supply growth MS1& MS2, interest rate, exchange rate and fiscal deficit). The OLS result indicates narrow money supply growth MS1, interest rate and fiscal deficit are positively related to inflation. While broad money supply MS2 and exchange were negatively related to inflation. However granger causality result revealed that there is a unidirectional causality running from money supply growth to inflation in Nigeria which is in tandem with classical quantity theory assertion. Finally, the study recommends a long term stabilization of monetary policy instrument especially the open market operation (OMO) and the need for government to reduce its deficit financing.
