In the context of information retrieval, traditional collection selection algorithms have been widely studied. These algorithms utilize language models, a representation of the contents of each text collection over which selection is to be performed, but these language models cannot always be easily acquired. Query-based sampling is a technique by which these language models are discovered by i...

in order to achieve success in today's competitive world, organizations should adapt to environmental changes. on the other hand, managers should have a set of values and ethical guidelines for their administrative and organizational functions. this study aimed to investigate the association between work ethics and attitudes towards organizational changes among the administrative, financial and...

It has long been hypothesized that urban areas exert a direct influence on precipitation patterns in their immediate surroundings (Horton, 1921). Early studies focused on this influence through the use of point-observation comparisons of urban and rural areas to quantify the anthropogenic effects on precipitation (AEP) (Changnon Jr., 1968, Huff and Changnon Jr., 1973, Huff and Schickedanz, 1974...

BACKGROUND The Work Limitations Questionnaire (WLQ) was recently developed to measure health-related decrements in ability to perform job roles among employed individuals. The purpose of this study was to develop and test a Japanese version of the WLQ. METHODS Developing the Japanese version of the WLQ involved translations, back-translations, and a pilot study. Using data obtained from a nat...

A face recognition system consists of two integrated parts: One is the face recognition algorithm, the other is the selected classifier and derived features by the algorithm from a data set. The face recognition algorithm definitely plays a central role, but this paper does not aim at evaluating the algorithm, but deriving the best features for this algorithm from a specific database through sa...

Rejection sampling is a technique for sampling from difficult distributions. However, its use is limited due to a high rejection rate. Common adaptive rejection sampling methods either work only for very specific distributions or without performance guarantees. In this paper, we present pliable rejection sampling (PRS), a new approach to rejection sampling, where we learn the sampling proposal ...

A major bottleneck in implementing sampling as a primitive relational operation is the inefficiency of sampling the output of a query. We highlight the primary difficulties, summarize the results of some recent work in this area, and indicate directions for future work.

introduction:today, shift work is considered as a necessity in many jobs and for some 24-hour services the use of shift-work is growing. however, shift work can lead to physiological and psycho-social problems for shift workers. this study aimed to determine the effects of shift work on the associated health problems, together with the demographic and job characteristics underlying the problems...
