Categorical models of the metalanguage FPC (a type theory with sums, products, exponentials and recursive types) are defined. Then, domain-theoretic models of FPC are axiomatised and a wide subclass of them —the non-trivial and absolute ones— are proved to be both computationally sound and adequate. Examples include: the category of cpos and partial continuous functions and functor categories o...

We give various internal descriptions of the category !-Cpo of !-complete posets and !-continuous functions in the model H of Synthetic Domain Theory introduced in 8]. It follows that the !-cpos lie between the two extreme synthetic notions of domain given by repleteness and well-completeness.

Synopsis Categorical models of the metalanguage FPC (a type theory with sums, products, exponentials and recursive types) are deened. Then, domain-theoretic models of FPC are axiomatised and a wide subclass of them |the non-trivial and absolute ones| are proved to be both computationally sound and adequate.

Comprehensive cancer care continues to improve in the United States, but many developing countries carry a high cancer burden. With limited resources, nurses in such countries often are unable to improve cancer detection and treatment or relieve patient suffering. The Oncology Nursing Society has developed collaborative relationships with many international organizations to educate nurses aroun...

BACKGROUND Because of the absence of adequate numbers of psychiatrists, the bulk of mental health care at the community level in Ghana is provided by community mental health workers (CMHWs). OBJECTIVE To examine the role and scope of practice of CMHWs in Ghana from their own perspectives and to make recommendations to improve the care they provide. DESIGN We conducted a cross-sectional surv...

We examined the outputs, sources of funding, and impact of European cancer research from 2002-13. Outputs were compared with the disease burden and individual countries' wealth. Funding came from a huge number of sources, particularly private-non-profit ones in northern and western Europe. Impacts were determined from citations on cancer clinical guidelines and in European newspaper stories abo...

The Joint Commission publishes its annual National Patient Safety Goals to guide accredited organizations in addressing high-risk, low-volume concerns related to patient safety. The 2010 list includes a goal to identify patients at risk for suicide, but do oncology nurses need to be concerned about the risk of suicide in patients with cancer?

An aging population and latent effects from exposure to carcinogens will likely augment the current trend of increased incidence of urinary bladder cancer. Intravesical antineoplastic therapy is a common treatment for urinary bladder cancer. Transurethral resection of bladder tumors often is followed immediately by the instillation of an antineoplastic agent in the operating room or postanesthe...

Objectives: Rapid and accurate screening for carbapenemase-producing organism (CPOs) in hospitalized patients is critical infection control prevention. The Xpert Carba-R assay designed rapid detection of CPOs, but 1 usually conducted only sample. We evaluated a pooling strategy CPO using the assay. Methods: Swab sets containing 2 swabs were collected from 415 unique at Peking University People’...
