We present a comprehensive study of the observational constraints on spatially flat cosmological models containing a mixture of matter and quintessence — a time varying, spatially inhomogeneous component of the energy density of the universe with negative pressure. Our study also includes the limiting case of a cosmological constant. We classify the observational constraints by red shift: low r...
Scientific theories often contain theoretical terms, such as “electron” and “proton”, that do not refer to observable entities or properties thereof. Within physics the concept of electron is used in theories about electric fields and magnetism. However, within chemistry, the electron is also used in thoeries to predict chemical properties and chemical reactions. While researchers have addresse...
background and objectives:breast cancer is the most common cancer among women worldwide. fine needle aspiration biopsy (fnab) is one of the methods of breast biopsy which is fast, easy and cost effective. the aim of this study was to evaluate the concordance rate between pathologic results of sonography or stereotaxy guided fnab and guided core needle biopsy (cnb) in the evaluation of breast le...
539 In this issue of Circulation, Samia Mora, Julie Buring, and Paul Ridker publish an elegant and clinically-relevant analysis examining discordance of low-density lipoprotein cholesterol (LDL-C) with related laboratory measures and the risk implications. The article should attract attention from a diverse set of contingents, such as those based in preventive cardiology, clinical lipidology, a...
The purpose of this note is to sharpen the results in Bouyssou and Pirlot (2005) giving an axiomatic characterization of concordance relations. We show how the conditions used in that paper can be weakened so as to become independent from the conditions needed to characterize a general conjoint measurement model tolerating intransitive and/or incomplete relations. This leads to a clearer charac...
The Patentatlas by Greif and Schmiedl (2002) represents an important source for patent data in Germany. Its use for industry-specific studies is however problematic because the correct assignment of patent data classified by technological fields to commonly used industry classifications is unclear. This paper presents an application-oriented approach to this issue. In using industryspecific R&D...
Outranking methods propose an original way to build a preference relation between alternatives evaluated on several attributes that has a definite ordinal flavor. Indeed, most of them appeal the concordance / non-discordance principle that leads to declaring that an alternative is “superior” to another, if the coalition of attributes supporting this proposition is “sufficiently important” (conc...
BACKGROUND Non-concordance with medication remains a major public health problem that imposes a considerable financial burden on the health care system, and there is still a need for studies on correlates of non-concordance. Our first aim is to analyse whether any of the individual characteristics age, educational level, financial strain, self-rated health, social participation, and trust in th...
