Natural selection is expected to leave distinctive signatures on patterns of neutral variation that are tightly linked to a site carrying an advantageous mutation. This notion is the basis for molecular population genetics approaches to the analysis of adaptations in the human genome. In principle, this is an attractive prospect; in practice, several complications and challenges make it difficu...

Load balancing middleware is used extensively to improve scalability and overall system throughput in distributed systems. Many load balancing middleware services are simplistic, however, since they are geared only for specific usecases and environments. These limitations make it hard to use the same load balancing service for anything other than the distributed application it was designed for ...

Projects are characterized by long working hours, complex tasks and being a kind of temporary organization. As such, work-family conflict is particularly prominent for project employees. This research examined whether and how work-family conflict affects professional commitment among Chinese project professionals. Research hypotheses were developed to explore the relationship between work-famil...

As STEM (Science, Technology, Engineering and Mathematics) education gets more attention from society, students' attitudes towards are increasingly concerned. However, there was scant research that has empirically documented the relations among attitude, learning motivation metacognition. This used Structural Equation Modeling to examine above relations. Data were collected 845 primary school s...

the task of balancing of assembly lines is well-known in mass production system but this problem is np-hard even for the simple straight line. therefore, utilizing heuristic methods for these problems is totally unquestionable. furthermore, in line with balancing problems, heuristic methods are the foundation of the metaheuristic methods, thus it seems to be necessary to use more efficient heur...
