BAREMO: How to Choose the Appropriate Software Component Using the Analytic Hierarchy Process

To select a software component from several similar candidates is a complex task, since each project pursues different objectives. We intend to use the Analytic Hierarchy Process in the taking of multicriteria decisions for software component reuse. This method is called BAREMO. It will help the software engineer to make estimations which will enable him/her to choose the appropriate component. The article presents a case study of the application of the method, where a project manager assesses a certain software component in order to consider its reuse in the domain of image processing

Understanding the Workweek of Foreign Born Workers in the United States

I analyze the length of the workweek of foreign-born workers in the U.S. I concentrate on workers supplying long hours of work − 50 or more weekly hours and document that immigrants are less likely than natives to work long hours. Surprisingly, these differences are greatest among highly educated and salary paid workers, and persists even after conditioning for demographic characteristics. I explain these differences with two within occupation characteristics. First, relative to natives, immigrants are less likely to supply long work weeks if they work in occupations where the immigrant-native earnings differential is big. Second, immigrants are also less likely to supply long work weeks when they work in occupations with a wide dispersion of earnings. This second result is important, because the occupation dispersion of earnings has been used to characterize changes of the worker's earnings over the worker life cycle (Bell and Freeman, 2001; Kuhn and Lozano, 2008), and a good measure of the incentives to supply long hours of work.hours of work, immigrants

More Than an Academic Question: Defining Student Ownership of Intellectual Property Rights

Intellectual property is increasingly important due to technology’s rapid development. The importance of intellectual property is also reflected within universities as traditional centers of research and expression, where students and faculty are encouraged to develop inventions and creative works throughout the educational experience. The commercialization potential of the intellectual property that emerges from these efforts has led many universities to adopt policies to determine ownership of intellectual property rights. Many of these policies take different approaches to ownership, and most students are unaware of their rights and are unlikely to consider whether the university has a claim to ownership. The purpose of this Article is to outline how intellectual property rights arise in the academic environment and to analyze how university policies determine ownership rights for students and the university. This Article concludes by urging universities and students to acknowledge the existence of these issues, adopt policies to address ownership rights, and make these policies known to members of the university community

Selection of Ontologies for the Semantic Web

The development of the Semantic Web has encouraged the creation of ontologies in a great variety of domains. Web users currently looking for ontologies in order to incorporate them into their systems, just use their experience and intuition. This makes it difficult for them to justify their choices. Mainly, this is due to the lack of methods that help the user to measure that the most appropriate ontologies for the new system are. To solve this deficiency, this work proposes a method which allows the users to measure the suitability of the existent ontologies, regarding the requirements of their systems

Gauged Lifshitz model with Chern-Simons term

We present a gauged Lifshitz Lagrangian including second and forth order spatial derivatives of the scalar field and a Chern-Simons term, and study non-trivial solutions of the classical equations of motion. While the coefficient beta of the forth order term should be positive in order to guarantee positivity of the energy, the coefficient alpha of the quadratic one need not be. We investigate the parameter domains finding significant differences in the field behaviors. Apart from the usual vortex field behavior of the ordinary relativistic Chern-Simons-Higgs model, we find in certain parameter domains oscillatory solutions reminiscent of the modulated phases of Lifshitz systems.Comment: 13 pages, 6 figure
