Glass patterns are a valuable tool to study the cortical stages of form perception. We use circular Glass patterns (cGP) to study the relation between form and color vision. The detection of Glass patterns is thought to be carried out in at least two stages. In the first stage, the local orientation information from the pairs of dots is analyzed. A later stage integrates this local orientation ...

The role of stressful life events in the etiology of various disorders has been of interest to investigators attempting to establish a link between stressful life events and disorders. None of the available scales are relevant to service personnel. In the present study an attempt was made to construct a scale to measure stressful life events in service personnel. In the first stage of study ope...

The purpose of this study was to determine whether the Physical Education Teacher Attitudes Toward Fitness Tests Scale (PETAFTS) produces reliable and valid scores. There were 4 stages and 4 sets of participants in the development of the PETAFTS. First, the domains of attitude were defined and cognitive and affective components were developed, organized, and validated. In the second stage, 134 ...

In this paper we develop and implement a methodology for analysing the sources of variation in environmental efficiency across producers. We formulate a two-stage model. In the first stage we use stochastic frontier analysis to estimate both technical and environmental efficiency. In the second stage we again use stochastic frontier analysis to regress estimated environmental efficiency scores ...

The Pandemonium Association Engine (PAE) [5,2,6] is proffered in an attempt to fulfil the cognitive necessities of an agent embodying true intelligence and common sense, and hopefully helping unify the main cognitive paradigms. The operation of the basic model and the performance of the second stage of development introducing imaginary concepts and goals are outlined, along with the principles ...

This paper investigates the relationship between relative earnings and giving in a twostage, real-effort experiment. In the first stage, four players compete in a tournament that determines their earnings. In the second stage, they decide whether they wish to transfer part of their earnings to one or more of their group members. Our main finding is that those who are ranked first are significan...

This paper considers critically the enterprise of naturalizing the subjective experience of acting intentionally. I specifically expose the limits of the model that conceives of agency as composed of two stages. The first stage consists in experiencing an anonymous intention without being conscious of it as anybody’s in particular. The second stage disambiguates this anonymous experience thanks...

Complex (second-order) channels have been useful in explaining many of the phenomena of perceived texture segregation. These channels contain two stages of linear filtering with an intermediate pointwise nonlinearity. One unanswered question about these hypothetical channels is that of the relationship between the preferred orientations of the two stages of filtering. Is a particular orientatio...

This chapter proposes a leak localization architecture and an associated methodology in Water Distribution Networks (WDNs) using pressure models and classifiers. In a first stage of the proposed architecture, residuals are obtained by comparing available pressure measurements with the estimations provided by a WDN model. In a second stage, a classifier is applied to the residuals with the aim o...

INTRODUCTION Collaborative testing is a learning strategy that provides students with the opportunity to learn and practice collaboration. This study aimed to determine the effect of collaborative testing on test performance and retention of course content in nursing students of Shiraz University of Medical Sciences, Shiraz, Iran. METHODS This quasi-experimental study was carried out on 84 st...
