We compare two different notions of generic expansions of countable saturated structures. On one hand there is a kind of genericity related to modelcompanions and to amalgamation constructions à la Hrushovski-Fräıssé; on the other, there is a notion of generic expansions defined via topological properties and Baire category theory. The second type of genericity was first formulated by Truss for...

Let CD be the category of all continuous domains and all mappings which preserve directed sups and the way-below relation. That is, a mapping f : P → Q is a morphism of CD if and only if f(sup D) = sup f(D) for any directed set D ⊂ P and f(x) œ f(y) if x œ y for any x, y ∈ P . We shall prove that the category CD is cartesian closed. 1991 Mathematics Subject Classification 06B35.

We give a duality for the variety of bounded distributive lattices that is not full (and therefore not strong) although it is full but not strong at the finite level. While this does not give a complete solution to the “Full vs Strong” Problem, which dates back to the beginnings of natural duality theory in 1980, it does solve it at the finite level. One consequence of this result is that altho...

Earlier this year, the introduction was announced of the Subject Category ‘Primary Health Care’ in Thomson Reuters Web of Science. In its Journals Citations Report 2010, this Category is now officially published (http://thomsonreuters.com/products_services/science/ science_products/a-z/web_of_science/). The list contains 13 (and not as initially expected 14) titles, ranked in Table 1 by Impact ...

This article examines and critiques the use of the term "vulnerability" in U.S. and international regulations and guidelines on research ethics. After concluding that the term is currently used in multiple, often inconsistent, senses, it calls on regulators to differentiate between three distinct types of vulnerability: "consent-based vulnerability,""risk-based vulnerability," and "justice-base...

The study focuses on the analysis of the information flow among the ISI subject categories and aims at finding an appropriate field structure of the Web of Science using the subject clustering algorithm developed in previous studies. The elaborate clustering of more than 8,000 journals and the clustering of the ISI subject categories provide two subject classification schemes through different ...

visualization of scientific maps enhances the awareness and general recognition of the scientific domains and their structures. it facilitates the study of the existing situation and planning of the future researches as well. the present study sought to discover and generate the scientific map of medicine in iran between 2003 and 2007. it also aimed to determine the most effective medical subje...

Subject categories of scholarly papers generally refer to the knowledge domain(s) which belong, examples being computer science or physics. category classification is a prerequisite for bibliometric studies, organizing scientific publications domain extraction, and facilitating faceted searches digital library search engines. Unfortunately, many academic do not have such information as part the...

In the scientific journals, being part of editorial boards, including journals' members and chief editors, involves holding positions power responsibility that affect running a journal. Until now, these have usually been held by men in most disciplines. this study, gender composition board (EBMs) editor-in-chief (ECs) 45 Women's Studies journals classified Journal Citation Report (JCR) was anal...
