This paper aims to study and examine the value systems among the students region of Islamic Azad universities. The population includes all students in academic year 2008-9 among whom 400 ones were selected from 10 universities as a sample. The students' value hierarchies were examined using Alpourt 45- item questionnaire(A.V.L). Descriptive and t-inferential statistics and multivariate variance...

The concept of co-allocation provides a simple mechanism to request and bind resources in a coordinated fashion in Grids across virtual organization boundaries. We have designed an advanced multistage co-allocation strategy based on resource hierarchies defined through user-specific patterns. The model manages simple flows between resources to perform managed job executions. We demonstrate the ...

—This paper presents an approach based on semantic annotation of CVs and job offers for automating recruitment on the web. The main idea consists on modeling formally the semantic content of these documents in term of their acquirements (case of a CV) or requirements (case of a job offer) using a shared ontology between recruiters and job seekers. The domain ontology built is inspired from the ...

Hall, Leung & Li have recently proposed a new model for human multitasking behavior. In their model, a primary job gets interruptions from all waiting jobs whenever it is being processed. Every time an interruption has been received, the worker switches from the primary job to the interrupting job. After part of the interrupting job has complete, the worker switches back to the primary job. Her...

This paper uses personnel records for workers employed by the Canadian Pacific Railway (CPR) between 1921 and 1944 to examine the extent to which observed career dynamics are consistent with the predictions of various models of internal labor markets. In addition, the findings provide new insight into how internal labor markets responded to Great Depression. Similar to some previous empirical s...

This paper presents a theoretical and empirical analysis of this decision and how it relates to wage setting and the provision of general training. The theoretical framework is a promotion tournament involving M competing firms with heterogeneous productivities, two-level job hierarchies, and a fixed number of managerial positions. This paper also considers an alternative model based on variati...

in the beginning of 1980s named as entrepreneurship decade, a large number of entrepreneurship researchers attempted to determine certain characteristics that distinguished entrepreneurs from non-entrepreneurs by identifying certain characteristics inherent in potential entrepreneurs in order to predict entrepreneurial behavior. among the characteristics identified, little empirical research ha...

Many speed-up techniques developed for accelerating the computation of shortest paths in road networks, like reach or contraction hierarchies, are based on the property that some streets are ’more important’ than others, e.g. on long routes the usage of an interstate is almost inevitable. In grids there is no obvious hierarchy among the edges, especially if the costs are uniform. Nevertheless w...

This paper gives two definability results in the local theory of the ω-enumeration degrees. First we prove that the local structure of the enumeration degrees is first order definable as a substructure of the ω-enumeration degrees. Our second result is the definability of the the classes Hn and Ln of the highn and lown ω-enumeration degrees. This allows us to deduce that the first order theory ...
