enterprise resource planning (erp) has become the most strategic tool for an organization to employ. a leading erp solution is sap®. it has been employed by organizations to enable them to collaborate on different projects and to integrate all aspects of operations. just as organizations have adopted erp solutions, they employed quality initiatives that are designed to help organizations maximi...

In this paper, by considering the notion of $Sigma$-hyperalgebras for an arbitrary signature $Sigma$, we study the notions of regular and strongly regular relations on a $Sigma$-hyperalgebra, $mathfrak{A}$. We show that each regular relation which contains a strongly regular relation is a strongly regular relation. Then we concentrate on the connection between the fundamental relation of $mathf...

Dr. Robert Barnes's masterly work, Lectures on Obstetric Operations, first published in 1870, has been to me a most useful guide and counsellor in obstetric difficulties of this kind. On page 378 of the fourth edition, 1886, Dr. Barnes gives a list of " certain cases of urgent disease of the mother, depending upon and complicating pregnancy?e.g., obstinate vomiting, with progressive emaciation,...

He lived, but having previously been a capable and efficient foreman, one with a well-balanced mind, and who was looked on as a shrewd smart business man, he was now fitful, irreverent, and grossly profane, showing little deference for his fellows. He was also impatient and obstinate, yet capricious and vacillating, unable to settle on any of the plans he devised for future action. His friends ...

given a graph $g$, let $g^sigma$ be an oriented graph of $g$ with the orientation $sigma$ and skew-adjacency matrix $s(g^sigma)$. then the spectrum of $s(g^sigma)$ consisting of all the eigenvalues of $s(g^sigma)$ is called the skew-spectrum of $g^sigma$, denoted by $sp(g^sigma)$. the skew energy of the oriented graph $g^sigma$, denoted by $mathcal{e}_s(g^sigma)$, is defined as the sum of the n...

In this paper the evolution of bargaining behavior is studied under the assumption that individuals might choose between obstinate and responsive strategies. Following Ellingson (1997) it is assumed that obstinate agents commit to a certain demand, whereas responsive agents adapt optimally to their opponents strategy. Agents change strategies due to imitation based on observations of the succes...
