This study evaluates the linkage of the ALWA survey with administrative labor market data from the German Federal Employment Agency. Exact, probabilistic or manual matches could be found for 86% of those respondents who consented to the linkage. Both the consent bias and the selectivity in linkage success are comprehensively examined based on survey and paradata. The results are informative for...

The dream-lag effect refers to there being, after the frequent incorporation of memory elements from the previous day into dreams (the day-residue), a lower incorporation of memory elements from 2 to 4 days before the dream, but then an increased incorporation of memory elements from 5 to 7 days before the dream. Participants (n=8, all female) kept a daily diary and a dream diary for 14 days an...

many large oil and gas fields in the most productive world regions happen to be fractured. the exploration and development of these reservoirs is a true challenge for many operators. these difficulties are due to uncertainties in geological fracture properties such as aperture, length, connectivity and intensity distribution. to successfully address these challenges, it is paramount to improve ...

Executive Summary/Abstract: The New York City Department of Health and Mental Hygiene has a pressing need to accurately identify individuals for a variety of public health purposes. This led to the construction of the Master Client Index (MCI). The system offers a department-wide service that provides fast, real-time processing of incoming medical records to determine whether the individual is ...

Abstract We apply the Darmois and $C^3$ matching conditions to three different spherically symmetric spacetimes. The exterior spacetime is described by Schwarzschild vacuum solution whereas for interior counterpart we choose perfect fluid solutions with same symmetry. show that are satisfied in all cases not fulfilled. argue this difference due a non-physical behavior of pressure on surface.

BACKGROUND Cohort matching and regression modeling are used in observational studies to control for confounding factors when estimating treatment effects. Our objective was to evaluate exact matching and propensity score methods by applying them in a 1-year pre-post historical database study to investigate asthma-related outcomes by treatment. METHODS We drew on longitudinal medical record da...

Let $G=(V,E)$ be a simple connected graph. A matching $M$ in a graph $G$ is a collection of edges of $G$ such that no two edges from $M$ share a vertex. A matching $M$ is maximal if it cannot be extended to a larger matching in $G$. The cardinality of any smallest maximal matching in $G$ is the saturation number of $G$ and is denoted by $s(G)$. In this paper we study the saturation numbe...

Analysis of coded communications and electronic patient record data present a unique opportunity for nursing knowledge discovery, the integration of communication content with clinical data. However, joint analysis of coded communications and clinical data depends on the ability to link waveform audio files with patient records. A procedure has been developed to link waveform audio files with T...

1. INTRODUCTION As a special case of their general theory of record linkage, Fellegi and Sunter (1969) presented a formal model for matching that uses the relative frequency of strings being compared. For instance, a surname that is relatively rare in pairs of records taken from two files has more distinguishing power than a common one. Most applications of frequency-based matching have used cl...
