Household Size and Socio-Economic Resources: A Case Study of Ika North East Local Government Area of Delta State of Nigeria
BA Ugbomeh
African Research Review , 2011,
Abstract: The paper examined the relationship between Household size and socioeconomic variables in Ika North-East Local Government Area of Delta State. Household size simply put, refers to the number of persons living together in the same house and share common catering arrangement, social and economic relationships and assist one another under a leader known as the head of household. The head of household could be a male or female. Socioeconomic resources are materials that human beings use their numbers, skills, and talents, labour, technical knowhow to produce in order to satisfy their interest and needs. A total of 2,245 questionnaires were administered using the stratified random sampling technique. Data was analysed using the multiple regression statistical technique. A high positive correlation of r = 0.787 between Household size and the identified socio-economic variables was recorded. Consequently, the hypothesis (Hi) for the study, that Household size is a function of socio-economic variables was accepted. The policy implications for the socio-economic development of Delta State in particular and Nigeria in general were heighted.

International Journal of Energy and Environment , 2010,
Abstract: Three resources, climate, biomass and social economic, all of which are essential to the production of household biogas in rural China, are evaluated for six areas whose boundaries are based on the average ground temperature at a depth of 1.6 m. This paper brings forward the index system for evaluating the household biogas resource potential, calculates the weighing of each index with Analytic Hierarchy Process (AHP) method. The evaluation results indicate that Area IV has the optimum region to develop household biogas in rural China; both Areas III and V are suitable; Area I is less-than-suitable; both Areas II and VI are unsuitable. A key recommendation is that investment patterns be modeled on the local availability of these resources.
Minimal Economic Distributed Computing  [PDF]

Abstract: In an ideal distributed computing infrastructure, users would be able to use diverse distributed computing resources in a simple coherent way, with guaranteed security and efficient use of shared resources in accordance with the wishes of the owners of the resources. Our strategy for approaching this ideal is to first find the simplest structure within which these goals can plausibly be achieved. This structure, we find, is given by a particular recursive distributive lattice freely constructed from a presumed partially ordered set of all data in the infrastructure. Minor syntactic adjustments to the resulting algebra yields a simple language resembling a UNIX shell, a concept of execution and an interprocess protocol. Persons, organizations and servers within the system express their interests explicitly via a hierarchical currency. The currency provides a common framework for treating authentication, access control and resource sharing as economic problems while also introducing a new dimension for improving the infrastructure over time by designing system components which compete with each other to earn the currency. We explain these results, discuss experience with an implementation called egg and point out areas where more research is needed.

Research Journal of Applied Sciences, Engineering and Technology , 2012,
Abstract: The large number of decision variables of long-term planning problem for improving the distribution system causes lots of complexities. The optimum allocation of Distributed Generation (DG) sources and determining their capacity in the deregulated electric market is a key way for capacity expansion of the distribution firm. In this study, a new approach is presented to determination the optimum location and capacity of DG sources in the deregulated electric market through the net present value analysis using an optimization model. This model aims to minimize the investment cost of the distribution firm, utility cost and the losses cost considering the anticipated load peak value. Considering the power market price anticipation to be indefinite, the proposed method is based on laying out the genetic algorithm and a fuzzy model to the power market price and the capacity expansion design of the distribution system during different time intervals is proposed along with two static and semi-dynamic methods. The efficiency of the proposed approach is well shown applying it to a sample network.
Renewable Resources, Capital Accumulation, and Economic Growth

Business Systems Research , 2011, DOI: 10.2478/v10305-012-0019-8
Abstract: This paper proposes a dynamic economic model with physical capital and renewable resources. Different from most of the neoclassical growth models with renewable resources which are based on microeconomic foundation and neglect physical capital accumulation, this study proposes a growth model with dynamics of renewable resources and physical capital accumulation. The model is a synthesis of the neoclassical growth theory and the traditional dynamic models of renewable resources with an alternative approach to household behavior. The model describes a dynamic interdependence among physical accumulation, resource change, and division of labor under perfect competition. Because of its refined economic structure, our study enables some interactions among economic variables which are not found in the existing literature on economic growth with renewable resources. We simulate the model to demonstrate the existence of equilibrium points and motion of the dynamic system. Our comparative dynamic analysis shows, for instance, that a rise in the propensity to consume the renewable resource increases the interest rate and reduces the national and production sector's capital stocks, wage rate and level of the consumption good. Moreover, it initially reduces and then increases the capital stocks of the resource sector and the consumption and price of the renewable resource. The stock of the renewable resource is initially increased and then reduced. Finally, labor is redistributed from the production to the resource sector.

Economic Analysis and Policy , 2011,
Abstract: Although it is widely accepted that the resources sector makes a significant contribution to national and state economies, information about how it impacts on local and regional economies is much scarcer. Understanding the spread of economic stimulus and subsequent indirect business and consumption effects is important because of the changing patterns of business operations, employment and supply chains in the resources sector. The focus of the research reported in this paper was to identify the geographical spread of economic impacts from the resources sector across Queensland. The results of the analysis demonstrate that incomes and expenditures from the resources sectors are widely distributed across the state, and generate significant flow-on effects. It is notable that the industry makes a strong direct contribution in many of the more remote areas of Queensland, helping to underpin economic conditions in those regions. Expenditure from the resources industry has indirect impacts on the business environment in many areas, and generates substantial levels of production in south-east Queensland and central Queensland in particular.
Coupled applications on distributed resources  [PDF]

Physics , 2006, DOI: 10.1016/j.cpc.2006.05.008
Abstract: Coupled models are set to become increasingly important in all aspects of science and engineering as tools with which to study complex systems in an integrated manner. Such coupled, hybrid simulations typically communicate data between the component models of which they are comprised relatively infrequently, and so a Grid is expected to present an ideal architecture on which to run them. In the present paper, we describe a simple, flexible and extensible architecture for a two-component hybrid molecular-continuum coupled model (hybrid MD). We discuss its deployment on distributed resources and the extensions to the RealityGrid computational-steering system to handle coupled models.
PEASANT ECONOMIC CALCULATION AND THE HOUSEHOLD ECONOMY IN IMPERIAL GERMANY  [cached]
John Abbot
Essays in Economic & Business History , 1999,
Abstract: Revisionist accounts of Imperial Germany, in stressing the progressive, rational, side to German agricultural development, have underestimated the degree to which older habits of peasant calculation continued to inform small and medium-scale enterprise. This paper surveys the lingering impact of household economic logics and imperatives—particularly those pertainingto inheritance and labor—upon peasant economic behavior and performance in rural Bavaria.
Economic potential of forest resources of Nepal  [PDF]

Banko Janakari , 2010, DOI: 10.3126/banko.v20i2.4803
Abstract: Nepal’s forest resources underpin the livelihoods of rural people in important ways. During the country's "planned development" over the past 50 years, the government, donors and policy makers have viewed these resources as a key vehicle for ushering in economic growth and for meeting basic needs. They underscore the potential value of forest resources for achieving conservation and socio-economic objectives. To what extent have economic incentives been generated to effectively harness these resources to meet the said objectives is an open question. To address this question, this paper reviews briefly and broadly the economic potential of the country’s forest resources in terms of forest goods and services. Estimates of economic potential of timber and non-timber forest products and environmental services have been assessed. A number of recommendations for realizing the potential for achieving development and poverty reduction objectives is provided. Key words: Forestry; non-timber forest products; ecosystem services; economic potential; livelihood DOI: 10.3126/banko.v20i2.4803 Banko Janakari Vol.20(2) 2010 pp.48-52
