Scheduling for the flexible job-shops has great importance in both fields of production management and combinatorial optimization. However, it is quite difficult to achieve an optimal solution to this problem with traditional optimization methods because of the high computational complexity. Considering several optimization criteria in this problem will bring on additional complexity and new pr...

A naturalistic field study investigated behavior toward pregnant (vs. nonpregnant) women in nontraditional (job applicant) and traditional (store customer) roles. Female confederates, who sometimes wore a pregnancy prosthesis, posed as job applicants or customers at retail stores. Store employees exhibited more hostile behavior (e.g., rudeness) toward pregnant (vs. nonpregnant) applicants and m...

Pilot-Job systems play an important role in supporting distributed scientific computing. They are used to consume more than 700 million CPU hours a year by the Open Science Grid communities, and by processing up to 1 million jobs a day for the ATLAS experiment on the Worldwide LHC Computing Grid. With the increasing importance of task-level parallelism in high-performance computing, Pilot-Job s...

Employees’ belief in the traditional work ethics of hard work and diligence as virtues in their own right has significantly declined in recent times in Taiwan. Job involvement as a mediator of the influence of work values on organizational commitment remains unclear, and needs to be explored in a non-western work context. In addition, the degree of organizational commitment has not been shown t...

BACKGROUND self-reported occupational histories are an important means for collecting historical data in epidemiological studies. An occupational history calendar (OHC) has been developed for use alongside a national occupational hazard surveillance tool. This study presents the systematic development of the OHC and compares work histories collected via this calendar to those collected via a tr...

Background. As there might be relevant differences with regard to research utilization in the general hospitals, we aimed to study research utilization among registered nurses working in traditional Chinese medicine hospitals. Methods. A total of 648 registered nurses from 4 tertiary-level hospitals in China were recruited for participation. A modified BARRIERS Scale and self-designed questionn...

In this paper I study the prevalence and cyclicality of job-to-job transitions using two micro datasets that allow one to identify workers who move from one job to another without an intervening spell of unemployment. I find that job-to-job flows are vast. More than half of all prime-age full-time workers who separate from their employer between two monthly interviews are employed in the second...

Methods Work process flow diagrams, with associated explanations and historical examples, were developed based on in-person, structured interviews with public health and preventative medicine analysts from a variety of Department of Defense (DoD) organizations, and with one organization in the Department of Health and Human Services (DHHS) and with a major U.S. city health department. The parti...

On the job search is a key feature of real life labor markets. Yet, traditional equilibrium unemployment theory has not been able to account for on-thejob search in a satisfactory manner. In this paper we present an equilibrium model which includes on-thejob search as an optimal response to search frictions and differences in firm productivity. Our model is laid out in detail in ongoing researc...
