Under conditions where several concepts are learned concurrently and concept instances are presented successively, the instances of any given concept may be presented in varying degrees of proximity to one another. At one extreme these may be presented one after the other without the interpolation of instances of any other concept, and at the other extreme two instances of a given concept may n...

Informal older adult caregiving allows older adults to stay in their homes or live with loved ones, but decisions surrounding older adult care are fraught with complexities. Related research and case law suggest that an older adult's need for and refusal of help are important considerations; the current study is the first to examine these factors experimentally. Two samples (potential caregiver...

Symbiosis is the phenomenon in which organisms of different species live together in close association. Symbiogenesis is the name given to the process by which symbiotic partners combine and unify. This letter reconsiders previous work using the NKCS model of coevolution to explore symbiogenesis. In particular, the role of different replication rates between the coevolving partners is considere...

One of the main problems in machine learning is to train a predictive model from training data and to make predictions on test data. Most predictive models are constructed under the assumption that the training data is governed by the exact same distribution which the model will later be exposed to. In practice, control over the data collection process is often imperfect. A typical scenario is ...

This publication contains information from a conference titled "Individual Perspectives on the Silent Epidemic of Viral Hepatitis in Hawai'i" held in October of 2007 with updates and additional contributions from annual conferences in 2008 and 2009. These conferences were sponsored by the Hepatitis Support Network of Hawai'i and held in Honolulu, Hawai'i at the Queen's Conference Center. The pr...

Analysts supporting homeland security via threat network analysis have a wide range of data sets at their disposal, and many link analysis technologies are capable of generating useful analytical information. While each data set provides critical information, and each tool has a unique set of strengths, not all tools are applicable to all data sets, even if the data is formatted in a way that t...

The advent of XML [XML04] has made it possible for various XML schemata, or document types, to co-exist. Questions then arise about how developers can write, or what support they can have to write, interoperable XML schemata and interoperable software and tools asociated with them. These XML schemata may originates from the same XML schema but have evolved and diversed over time. This paper des...

A dvocacy can be a powerful force for change and those who work with children are the best advocates for the next generation. Drs Hawkins and Law have surveyed the pattern of research funding available for child and family health and have looked to see how this correlates with the government priorities for children set in the National Service Framework for Children and other government policy d...

Queuing theory and statistical methods are used in this paper to derive formulas for determining average turnaround time in teleprocessing systems that handle messages on a priority basis. This information is needed to ensure, for example, that messages are processed within acceptable time limits and that eficient use is macle of system resources. Factors considered in arriving at the formulas ...

Bilateral Testicular tumours are rare. A teratoma followed by a seminoma is one of the most uncommon forms of presentation. A case is described in a 29 year old soldier with a review of the literature and a discussion of the problems associated with diagnosis.
