This paper deals with the improvement of fatigue life of AISI 1040 steel components by using a High Power Diode Laser (HPDL). First, the meaningfulness of each operational parameter was assessed by varying the experimental laser power and scan speed. After laser treatment, fatigue tests were performed to investigate the influence of laser processing parameters on the material resistance. The fa...

BACKGROUND Lung cancer has had a low survival rate throughout the years. Some studies have shown that psychological variables such as hardiness and resiliency may play a role in the meaningfulness of survival among lung cancer patients. OBJECTIVE The objective of this systematic review was to synthesize the best available evidence on the experiences of surviving lung cancer (including psychol...

This paper will give a description of all continuous functions which are comparison meaningful in the sense of measurement theory. Copyright 2001 Academic Press.

The present article argues for what is essentially a return to the functionalist approach to investigation of memory. Two experiments demonstrate that the effects of level of processing depend on scaled meaningfulness of the material and study time. Data from those experiments along with data currently in the literature are then reanalyzed to examine the effect of repetitions. Of particular int...

Abstract Objective The present study examines the bidirectional nature of associations between parenthood and mental well-being using 36-year longitudinal data. Background Mental can affect if when one becomes a parent (selection hypothesis), characteristics (causation hypothesis). However, life course research has infrequently studied these hypotheses in parallel. Previous studies have also ty...

OBJECTIVES In individuals with chronic pain (ICPs), controlling pain often is a salient goal, despite the difficulty to achieve it. This situation may bring along frustration and distress. Yet much remains unknown about the content, appraisal, and structure of goals that ICPs pursue. Here, we explore these goals, and specifically focus upon possible differences and interrelations between pain c...
