PURPOSE The purpose of this study was to examine differences, interactions, and associations among cognition, fluid intake, and demographic variables that may affect length of stay (LOS) for psychogeriatric inpatients aged 65 years or older. DESIGN AND METHODS Descriptive, comparative, correlational secondary analysis of data from a primary study of 202 inpatients. FINDINGS Older adults wit...

BACKGROUND The current rise in employment is improving forecasts for the future supply of registered nurses; however sizeable shortages are still projected. With the intention of improving academic success in nursing students, related factors need to be better understood. OBJECTIVES The purpose of the correlational study was to describe the relationship between emotional intelligence, psychol...

A descriptive correlational design was used to examine the clinical decision making of nurses regarding elder abuse. The relationship of the nurses' applied knowledge of elder abuse, years of experience as a Registered Nurse (RN), clinical level of practice status, the use of intuition, and clinical decision outcomes for patients in cases of suspected elder abuse were examined. The convenience ...

The objective of this study was to test a causal model of work wellness for engineers, technicians and electricians in an electricity supply organisation. An ex post facto correlational design was used. The participants included 38 engineers, 86 technicians and 91 electricians in an electricity supply organisation. The Maslach Burnout Inventory – General Survey, the Utrecht Work Engagement Scal...

Two experiments investigated free sorting, a type of unsupervised learning, with multiattribute drawings of alien animals. In previous research on concept formation, with simpler stimulus structure than ours, participants were insensitive to correlational structure in the stimuli, producing primarily "ID sorts," based on the values ofjust 1 dimension or attribute. Our experiments showed that pa...

Literal acceptance of the results of fitting "causal" models to correlational data can lead to conclusions that are of questionable value. The long-established principles of scientific inference must still be applied. In particular, the possible influence of variables that are not observed must be considered; the well-known difference between correlation and causation is still relevant, even wh...

Snoring detection is important for diagnosing obstructive sleep apnea syndrome (OSAS) and other respiratory sleep disorders. In general, audio signal processing such as snoring sound analysis uses the frequency characteristics of the signal. Recently, a correlational filter Multilayer Perceptron neural network (f-MLP) has been proposed, which has the first hidden layer of correlational filter o...

Correlation clustering is a concept of machine learning. It was introduced in Bansal et al. [2], which gives a good overview of the mathematical background as well. Let G be a complete graph on n vertices and label its edges with + or − depending on whether the endpoints have been deemed to be similar or different. Consider a partition of the vertices. Two edges are in conflict with respect to ...

BACKGROUND Major life changes are among factors that cause anxiety, and one of these changes is surgery. Emotional reactions to surgery have specific effects on the intensity and velocity as well as the process of physical disease. In addition, they can cause delay in patients recovery. This study is aimed at determining the relationship between religious beliefs and preoperative anxiety. MET...

We define correlational ~von Neumann! entropy for an individual quantum state of a system whose timeindependent Hamiltonian contains random parameters and is treated as a member of a statistical ensemble. This entropy is representation independent, and can be calculated as a trace functional of the density matrix which describes the system in its interaction with the noise source. We analyze pe...
