OBJECTIVE To examine breast-feeding and complementary feeding practices during the first 6 months of life among Norwegian infants of Somali and Iraqi family origin. DESIGN A cross-sectional survey was performed during March 2013-February 2014. Data were collected using a semi-quantitative FFQ adapted from the second Norwegian national dietary survey among infants in 2006-2007. SETTING Somal...

A logical spreadsheet is a spreadsheet in which the formula language is composed of logical expressions. Logical spreadsheets were invented shortly after traditional electronic spreadsheets were introduced, but since then logical spreadsheet research has been somewhat sparse. Recently, however, there has been a resurgence in interest of logical spreadsheets in the research community. In this ar...

Linear Temporal Logic (LTL) is widely used for defining conditions on the execution paths of dynamic systems. In the case of dynamic systems that allow for nondeterministic evolutions, one has to specify, along with an LTL formula φ, which are the paths that are required to satisfy the formula. Two extreme cases are the universal interpretationA.φ, which requires that the formula be satisfied f...

We show that the incentives a vertically integrated supplier may have to disadvantage or “sabotage” the activities of downstream rivals vary with both the type of sabotage and the nature of downstream competition. Cost-increasing sabotage is typically profitable under both Cournot and Bertrand competition. In contrast, demand-reducing sabotage is often profitable under Cournot competition, but ...

The concept of the integrated database system based on database logic is presented. The idea of an integrated database system may be used to deal with several database structures: hierarchical, network, relational, etc , applying one common data model. In the presented approach the relational model is established as a common view of different databases. The following parts of an integrated data...

Wikipedia is an online encyclopedia created on the web by various participants. Although it is not created for the purpose of helping studies in language processing, its size and well-formed structure is attracting many researchers in the area. In this review, we selected five characteristic papers to show various creative uses of Wikipedia within the three years.

This paper presents a general, mathematically rigorous approach to nonlinear planning that handles both complex goals and actions with context-dependent effects. A goal can be any arbitrary well-formed formula containing conjunctions, disjunctions, negations, and quantifiers. Actions are likewise not constrained and can have an unrestricted number of complex, situation-dependent effects. The ap...
