Therapeutic metaphors and personal meanings in group poetry therapy for people with schizophrenia
2021
This article concerns the therapeutic potential of metaphor in group poetry therapy, concentrating on the poetry therapy process of people diagnosed with schizophrenia. The data was collected in a one-year poetry therapy group. The main questions were: (1) What kind of therapeutic potential can metaphors offer in group poetry therapy? (2) What are the personal meanings and evaluations that the participants give to the therapy process and its effects on their lives? (3) What are the most significant elements in poetry therapy from the viewpoint of the client? The analysis was based on the Grounded theory method. The results showed that the most significant therapeutic factors of the process …
Fuzzy-logic-based approach for identifying objects of interest in the PRIDE framework
2008
On-road autonomous vehicle navigation requires real-time motion planning in the presence of static and moving objects. Based on sensed data of the environment and the current traffic situation, an autonomous vehicle has to plan a path by predicting the future location of objects of interest. In this context, an object of interest is a moving or stationary object in the environment that has a reasonable probability of intersecting the path of the autonomous vehicle within a predetermined time frame. This paper investigates the identification of objects of interest within the PRIDE (PRediction In Dynamic Environments) framework. PRIDE is a multi-resolutional, hierarchical framework that predi…
A neural network based automatic road signs recognizer
2003
Automatic road sign recognition systems are aimed at detection and recognition of one or more road signs from real-world color images. In this research, road signs are detected and extracted from real world scenes on the basis of their color and shape features. A dynamic region growing technique is adopted to enhance color segmentation results obtained in the HSV color space. The technique is based on a dynamic threshold that reduces the effect of hue instability in real scenes due to external brightness variation. Classification is then performed on extracted candidate regions using multilayer perceptron neural networks. The obtained results show good detection and recognition rates of the…
Colour image segmentation and labeling through multiedit-condensing
1992
Abstract A new method is proposed for detecting and locating objects of interest within a colour scene under very strong variabilities in lighting conditions, object shape and pigmentation. The method is based on Nearest Neighbour classification and Multiedit-Condensing techniques and is applied to implement the vision subsystem of a robotic citric harvesting device. Experiments and results are reported showing the effectiveness of the method and illustrating its appropriateness to the proposed task.
Shape indices to identify regional differences in otolith morphology of comber, Serranus cabrilla (L., 1758)
2003
Summary Sagittal otoliths from the Atlantic and Mediterranean regions of Serranus cabrilla L. were compared using shape indices (form-factor, roundness, circularity, rectangularity, ellipticity and eccentricity). Regional differences were best described by form-factor, circularity and eccentricity variables. The canonical discriminant functions were built with form-factor or rectangularity indices. The results indicated slight regional variations. The G-test was the criterion more useful to identify the otolith origin in the discriminant analysis.
J-MADeM, a market-based model for complex decision problems
2010
This paper presents J-MADeM, a multi-modal decision making mechanism to provide agents in a Multi-Agent Systems (MAS) with a market-based model for complex decision problems. J-MADeM is now available as an open source library fully integrated into Jason, the successful interpreter for the AgentSpeak programming language. The aim of this work is to improve Jason by incorporating an agent decision-making module able to merge multiple information sources received from the rest of the agents. This information is modeled as a set of utility functions expressing the preferences of the agents for a specific problem. Then, J-MADeM agents use one-round sealed-bid combinatorial auctions as the main p…
Group algebras whose units satisfy a group identity
1997
Let F G FG be the group algebra of a torsion group over an infinite field F F . Let U U be the group of units of F G FG . We prove that if U U satisfies a group identity, then F G FG satisfies a polynomial identity. This confirms a conjecture of Brian Hartley.
Using Redundant Visual Information From Different Dimensions for Attentional Selection
2012
The present study investigated the use of redundant information for attentional selection of a visual object. Each display contained two overlapping objects, and participants had to report the color of the occluding object. A baseline condition did not require object selection because the objects were identical. A single-cue condition required object selection based on spatial arrangement (i.e., occlusion) because the objects had the same shape. A double-cue condition afforded object selection by occlusion and shape because the objects consistently differed in shape. Behavioral results showed that the redundant shape cue facilitated attentional selection, although participants were never s…
The Development of Spatial Location in Finnish
1991
Abstract The purpose of this research was to study the shift from mono- to bi-referential spatial location in the language of Finnish children. Monoreferential location is based on the intrinsic properties of a referent object and the proximity relationship, and bireferential location requires coordinated spatial relationships involving referent objects and a projective relationship. Locative expressions which are monoreferential include: in/on/under and intrinsic front/back, and those which are bireferential include deictic front/back and between. A pictorial representation of locative relationships with a sentence-picture matching task was used to present the mono- vs bi-referential contr…
Compaction of Open-Graded HMAs Evaluated by a Fuzzy Clustering Technique
2015
The aim of this paper is the proposal of an expeditious procedure to be used during the execution of an asphalt layer for improving the compaction task. This procedure, based on a fuzzy clustering technique, starts from the knowledge of some information recorded by ordinary measuring instruments and provides an aid to the decision-maker on the number of roller passes needed to achieve a specific density at a certain temperature. This result can be deduced with great rapidity during the paving operations on site without waiting for the time spent in the core extraction and in the subsequent laboratory analysis. In this way it is possible to identify more precisely which aspects of the execut…
