We consider cDNA microarray experiments when the cell populations have a factorial structure, and investigate the problem of their optimal designing under a baseline parametrization where the objects of interest differ from those under the more common orthogonal parametrization. First, analytical results are given for the 2× 2 factorial. Since practical applications often involve a more complex...

In order to provide evidence of validity and reliability of the instruments to evaluate the quality of working life, this study assesses the factorial structure and the reliability of the UWES-17 scale, measuring Engagement or employment commitment. A group of 165 Chilean Health workers were surveyed from various health disciplines and contract quality, the majority being women (70.30%) and non...

The Theory of Planned Behavior (TPB) is one of the main theoretical models in the study of the different variables, which influence in the practise of physical activity. The aim in this study was to develop a questionnaire based on TPB in physical activity context providing evidence for the validity of the obtained measures. The instrumental project included three independent studies. The first...

Burnout is a variable that continues to sustain international research interest. The most widely adopted tool measuring the burnout syndrome is the Maslach Burnout Inventory (MBI). The present study attempted to examine the psychometric properties and factorial structure of the MBI amongst a sample of 536 professional health specialists in Greece. The results indicated satisfactory reliability ...

BACKGROUND Professional Social Responsibility is now imperative for the practice of medicine. However, there are no instruments to assess it among physicians. AIM To construct and evaluate the factorial structure and reliability of a questionnaire designed to measure socially responsible behavior in physicians. MATERIAL AND METHODS The Questionnaire on Medical Socially Responsible Behavior,...

This study explored how individuals apply features of personality disorders (PDs) to peers. Members of groups nominated peers who exhibited symptoms for each of the 10 PDs in the DSM-IV. Data were gathered in 2 samples: 1st-year college students (n = 1,440) and Air Force recruits (n = 2,075). The peer method reliably identified group members exhibiting specific PD features. Factor analyses iden...

We consider discrete-time factorial Markov Decision Processes (MDPs) in multiple decision-makers environment for infinite horizon average reward criterion with a general joint reward structure but a factorial joint state transition structure. We introduce the “localization” concept that a global MDP is localized for each agent such that each agent needs to consider a local MDP defined only with...

Inferences we make about underlying cognitive processes can be jeopardized in two ways due to problematic forms of aggregation. First, averaging across individuals is typically considered a very useful tool for removing random variability. The threat is that averaging across subjects leads to averaging across different cognitive strategies, thus harming our inferences. The second threat comes f...

BACKGROUND Pain is a multidimensional experience. Locus of control is an important factor related to chronic pain experience and treatment. There is a gap in the literature when discussing issues related to pain evaluation in elderly. OBJECTIVES To analyze the factorial structure, intra and inter-rater reliability of the Brazilian version of the Pain Locus of Control Scale - Form C for elderl...
