Urine Testing During Treatntent Predicts Cocaine Abstinence
2010
The objective of this study was to analyze the influence of the variables that predict cocaine abstinence on an outpatient program for the treatment of addiction to this substance. Participants were 80 patients (85% men and 15% women) selected at random from those receiving treatment at a Spanish health service outpatient unit. For detecting the predictor variables the authors carried out a chi-square automatic interaction detection (CHAID) analysis. Logistic regression analysis and discriminant analysis were performed to estimate the probability of abstinence according to/using the predictor variables detected by CHAID analysis. Abstinence rate after six months of treatment was 37.5%. The …
A Feature Rich Distance-Based Many-Objective Visualisable Test Problem Generator
2019
In optimiser analysis and design it is informative to visualise how a search point/population moves through the design space over time. Visualisable distance-based many-objective optimisation problems have been developed whose design space is in two-dimensions with arbitrarily many objective dimensions. Previous work has shown how disconnected Pareto sets may be formed, how problems can be projected to and from arbitrarily many design dimensions, and how dominance resistant regions of design space may be defined. Most recently, a test suite has been proposed using distances to lines rather than points. However, active use of visualisable problems has been limited. This may be because the ty…
Design, development and validation of a system for automatic help to medical text understanding
2020
Abstract Objective The paper presents a web-based application, SIMPLE, that facilitates medical text comprehension by identifying the health-related terms of a medical text and providing the corresponding consumer terms and explanations. Background The comprehension of a medical text is often a difficult task for laypeople because it requires semantic abilities that can differ from a person to another, depending on his/her health-literacy level. Some systems have been developed for facilitating the comprehension of medical texts through text simplification, either syntactical or lexical. The ones dealing with lexical simplification usually replace the original text and do not provide additi…
A Visualizable Test Problem Generator for Many-Objective Optimization
2022
Visualizing the search behavior of a series of points or populations in their native domain is critical in understanding biases and attractors in an optimization process. Distancebased many-objective optimization test problems have been developed to facilitate visualization of search behavior in a two-dimensional design space with arbitrarily many objective functions. Previous works have proposed a few commonly seen problem characteristics into this problem framework, such as the definition of disconnected Pareto sets and dominance resistant regions of the design space. The authors’ previous work has advanced this research further by providing a problem generator to automatically create use…
Development Perspectives for Higher Education Research and Practice
2016
In the 24 collaborative projects of the KoKoHs program, comprising more than 70 individual research projects, objective test instruments were developed for assessing the competencies of students and graduates and tested in higher education practice (see table in section 8). The KoKoHs assessments provide empirically substantiated information on students’ competency levels and insight into the effectiveness of teaching-and-learning opportunities in higher education. KoKoHs has offered means to address major challenges of higher education in a more effective manner and, in the long term, contributed to improving structural, organizational, and individual conditions for teaching and learning a…
