Four studies explored people's judgments about whether particular types of behavior are compatible with determinism. Participants read a passage describing a deterministic universe, in which everything that happens is fully caused by whatever happened before it. They then assessed the degree to which different behaviors were possible in such a universe. Other participants evaluated the extent t...

the authors have developed methods to characterize and quantify uncertainty in acoustic environmental predictions. We have developed methods for reflecting this uncertainty in tactical systems such as senor performance prediction, search plan recommendation, and track and detect systems that rely on environmental inputs. Uncertainty in performance prediction can result from model error and unce...

Alcohol primarily interferes with the ability to form new long-term memories, leaving intact previously established long-term memories and the ability to keep new information active in memory for brief periods. As the amount of alcohol consumed increases, so does the magnitude of the memory impairments. Large amounts of alcohol, particularly if consumed rapidly, can produce partial (i.e., fragm...

Real radar data containing a small manoeuvring boat in sea clutter was processed using a grid based finite difference implementation of continuous-discrete filtering. An examination was undertaken to determine the appropriate dynamic, target amplitude and clutter amplitude models which should be utilized to allow the successful application of Track Before Detect techniques (TkBD). Both two dime...

Track-before-Detect (TBD) methods have been applied in the fields of dim target detection in radar systems. The basic principle of TBD is actually the theory of multiple frame integration detection, that is, using the multiple scans data to detect the dim target by accumulation effect which make use of information about target motion trajectory to increase the target detection capability of a s...

Do labor regulations influence the reaction of stock markets and firm profitability to cross-border acquisitions? We discover that acquiring firms enjoy smaller abnormal stock returns and profits when targets are in countries with stronger labor protection regulations, i.e., in countries where laws, regulations, and policies increase the costs to firms of adjusting their workforces. These effec...

Understanding the causes of architecture changes allows us to devise means to prevent architecture knowledge vaporization and architecture degeneration. But the causes are not always known, especially in open source software (OSS) development. This makes it very hard to understand the underlying reasons for the architecture changes and design appropriate modifications. Architecture information ...

University of Texas at Austin University of Texas at Austin Austin, TX 78712 Austin, TX 78712 ([email protected]) ([email protected]) Abstract The partial-order model of distributed computations based on the happened before relation has been criticized for allowing false ca...

The low level of volatility observed in appraisal-based commercial property indices relative to other asset classes has been frequently noted and extensively commented on in the Real Estate finance literature. However, the volatility of such commercial property indices is only one source of information on the second moment of commercial property returns. The volatility of securitised property r...

AnswerBus News Engine' is a question answering system using the contents of CNN Web site2 as its knowledge base. Comparing to other question answering systems including its previous versions, it has a totally independent crawling and indexing system and a fully functioning search engine. Because of its dynamic and continuous indexing, it is possible to answer questions on just-happened facts. A...
