Motivated by the recent study on categorical properties of latticevalued topology, the paper considers a generalization of the notion of topological system introduced by S. Vickers, providing an algebraic and a coalgebraic category of the new structures. As a result, the nature of the category   TopSys   of S. Vickers gets clari ed, and a metatheorem is stated, claiming that (latticevalu...

PURPOSE/OBJECTIVES To develop a substantive theory that explains how African American women aged 50 years and older of different socioeconomic status (SES) make decisions about mammography screening. DESIGN Qualitative, grounded theory. SETTING Churches, places of employment, or women's homes in a large city in Ohio. SAMPLE 30 women aged 52-72 years; 16 in the initial sample and 14 in the...

A key component for estimating the optimal size and structure of disability insurance (DI) programs is the elasticity of DI claiming with respect to benefit generosity. Yet, in many countries, including the United States, all workers face identical benefit schedules, which are a function of one's labor market history, making it difficult to separate the effect of the benefit level from the effe...

While CaMKII has long been known to be essential for synaptic plasticity and learning, recent work points to new dimensions of CaMKII function in the nervous system, revealing that CaMKII also plays an important role in synaptic organization. Ca(2+)-triggered autophosphorylation of CaMKII not only provides molecular memory by prolonging CaMKII activity during long-term plasticity (LTP) and lear...

Non-inferiority (NI) trials attempt to demonstrate that the loss in efficacy by a new treatment compared to a standard treatment is limited to a certain pre-specified margin, usually compensated by some form of benefit in the form of safety, ease in administration, tolerability, costs, etc. The lack of mention of the benefit of the new treatment and its importance have been pointed out recently...
