To complement the previous attempts to define the elusive concept of entrepreneurship, this study examines the impact of firm origin on small business owners/entrepreneurs and the characteristics of their firms. A review of previous typologies is presented along with a categorization of the groups of business owners/entrepreneurs from those typologies into three basic groupings: 1) Creators, mo...

For general memoryless systems, the typical information theoretic solution when exists has a “single-letter” form. This reflects the fact that optimum performance can be approached by a random code (or a random binning scheme), generated using independent and identically distributed copies of some single-letter distribution. Is that the form of the solution of any (information theoretic) proble...

Business Process Management aligns organisational strategy and business operation. The dynamic environment within which organisations operate promotes changes in business processes, in a phenomenon known as business process variability. The goal of this research is reviewing business process variability literature to comprehend this phenomenon and analyse its theoretical foundation. Through a s...

Many waste utilities managers and some think-tankers have considered the waste market as one of the best macroeconomic indicators of a country (US.EPA, 1999). They defend that the production of waste is deeply linked to the financial health of the citizens (O’Neil & Locke, 2004) and, therefore, to the financial health at a national level. Figure 1 shows the growth of urban waste in line with th...

Future shop-floors are going to evolve as they need to be able to fully respond to dynamic adaptations and sophisticated interactions with the enterprise systems. This trend is fully backed up by the ever increasing capabilities of the new generation of devices that feature advanced communication as well as computational capabilities. However as the transition to the future infrastructure will ...

Electric utilities are increasingly aware of the potential of IT and its impacts on their business operation. However, in order for a utility to be able to translate all these potentials into real benefits, an IT strategy is needed to manage the developments, acquisitions, and the utilization of IT systems within the organization. Today, quite a few electric utilities have prepared or are in th...

Given a finite (connected) simplicial graph with groups assigned to the vertices, the graph product of the vertex groups is the free product modulo the relation that adjacent groups commute. The graph product of finitely presented infinite groups is both semistable at infinity and quasi-simply filtrated. Explicit bounds for the isoperimetric inequality and isodiametric inequality for graph prod...

Mathematical models and optimization problems can be a valuable tool to optimize the operational design of bioreactors. In present contribution bioreactor model, implementing in-situ product removal (ISPR) is presented used demonstrate potential real world strategies that applied system. Different objectives are formulated in order find (i.e. designs) maximize yield and/or productivity. The dec...

Knowledge management plays a very important role in business operation, especially in the efficient exploitation of information or knowledge resources through technology. Technology provides the basic tools for implementing and improving the efficiency of knowledge management activities within an enterprise. To understand the relative influence of various factors in improving knowledge manageme...

An enterprise cooperative environment is combination of emerging technologies and methodologies on which both enterprise employee and customers can perform necessary business activities. A business activity will involve many systems of an enterprise. Integration between those systems becomes a critical issue because inter-/intraenterprises will have heterogeneous systems. Recently, many new tec...
