Chain restaurants will soon need to disclose calorie information on menus, but research on the impact of calorie labels on food choices is mixed. This study tested whether calorie information presented in different formats influenced calories ordered and perceived restaurant healthfulness. Participants in an online survey were randomly assigned to a menu with either (1) no calorie labels (No Ca...

In this short note we want to characterize the groups isomorphic to full automorphism groups of ordered abelian groups. The result will follow from classical theorems on ordered groups adding an argument from proofs used to realize rings as endomorphism rings of abelian groups, see [2]. Recall that H is a right ordered group (RO-group) if (H, ·) is a group and (H,<) is a linear order satisfying...

BACKGROUND Criteria are needed for primary care providers such that they can evaluate age-related knee pain in a cost-effective manner. This study examined (1) in what percentage of patients are appropriate radiographic views of the knee ordered before magnetic resonance imaging (MRI) for knee pain, (2) specialists' retrospective evaluation for appropriate utilization of MRI in knee pain, and (...

Archimedean classes and convex subgroups play important roles in the study of ordered groups. In this paper, we show that ACA0 is equivalent to the existence of a set of representatives for the Archimedean classes of an ordered abelian group. Hahn’s Theorem is the strongest known tool for classifying orders on abelian groups. It states that every ordered abelian group can be embedded into produ...

We show how the concept of an annotated ordered set can be used to model large taxonomically structured ontologies such as the Gene Ontology. By constructing a formal context consistent with a given annotated ordered set, their concept lattice representations are derived. We develop the fundamental mathematical relations present in this formulation, in particular deriving a conceptual pre-order...

Abstract Aim To determine the necessity and cost effectiveness of routine blood group save tests (G&amp;S) before thyroidectomy Background Sub-total or total is mainstay treatment for several thyroid disorders. The incidence post-thyroidectomy haemorrhage has been reported between 0.36% 4.3% in literature. Many patients undergo G&amp;S testing anticipation a peri-operative requiring transfusion...

This paper deals with the revision of partially ordered beliefs. It proposes a semantic representation of epistemic states by partial preorders on interpretations and a syntactic representation by partially ordered belief bases. Two revision operations, the revision stemming from the history of observations and the possibilistic revision, defined when the epistemic state is represented by a tot...
