Health procrastination: The experience of 35-44 years old men
2018
The focal concept of this study is health procrastination. Delay in seeking help from medical practitioners is an increasing problem in Latvia, particularly with men between the ages of 35-44. Failures in primary and secondary prevention create a number of negative consequences, for instance, longer and more complex treatment; lower recovery prognosis as well as higher treatment costs. Nevertheless, the aforementioned group often avoids medical treatment. The aim of this study was to understand the experience of 35-44 years old men in terms of their health procrastination in qualitative terms. Semi-structured in-depth interviews with 48 men within the age range of 35-44 years were conducted…
Collaborative processes during report writing of a science learning project: The nature of discourse as a function of task requirements
2000
The aim of this article is to specify how different aspects of task assignments are related to different types of student discourse during the report writing phase of a science learning project. A group of four ninth-grade students of the Finnish comprehensive school (about 15-year-olds) participated in a project work involving laboratory experiments, reading literature, and analysing and reporting research findings. The empirical data were collected through videotaping and interviews in authentic classroom settings. The results indicated that construction of shared, high-level understanding was quite rare in this case of small group interaction. As one of the main reasons for this, we sugg…
The computational complexity of the criticality problems in a network with interval activity times
2002
Abstract The paper analyzes the criticality in a network with interval activities duration times. A natural generalization of the criticality notion (for a path, an activity and an event) for the case of network with interval activity duration times is given. The computation complexity of five problems linked to the introduced criticality notion is presented.
Results of a literature review on methods for estimating buildings energy demand at district level
2019
Abstract In the framework of distributed energy planning, evaluating reliable energy profiles of different sectors has a prominent role. At the same time, it is a quite challenging task, since the availability of actual energy profiles of buildings at the district level is not widespread. A survey of over 70 studies in scientific literature has been accomplished and a set of criteria has been defined for classifying the selected contributions based on the energy demand data features, source and/or estimation methods, highlighting the ones adopting hourly energy profiles. As final results, tables summarizing the main methods characteristics and a selection of studies providing directly useab…
Educar moralmente desde la experiencia del coronavirus
2020
Existe a menudo una cierta desconfianza ante las propuestas de educación moral. Sin embargo, desde siempre los humanos han intentado (sobre)vivir y además vivir bien. Y de eso trata la educación moral, de aprender a vivir lo mejor posible. Pero, aunque de entrada se suele creer que eso es fácil de saber, no es así, sino que se trata de una tarea muy difícil, que requiere prestar atención a la experiencia (a lo que nos pasa) y dedicar mucho esfuerzo reflexivo para saber a qué atenerse en cada circunstancia y orientarse en ella.
On the use of a metric-space search algorithm (AESA) for fast DTW-based recognition of isolated words
1988
The approximating and eliminating search algorithm (AESA) presented was recently introduced for finding nearest neighbors in metric spaces. Although the AESA was originally developed for reducing the time complexity of dynamic time-warping isolated word recognition (DTW-IWR), only rather limited experiments had been previously carried out to check its performance in this task. A set of experiments aimed at filling this gap is reported. The main results show that the important features reflected in previous simulation experiments are also true for real speech samples. With single-speaker dictionaries of up to 200 words, and for most of the different speech parameterizations, local metrics, a…
From Marketing Mix to e-Marketing Mix: a literature overview and classification
2009
The marketing mix paradigm, in its famous version of the 4Ps, went all the way through the evolution of marketing theory: from the marketing concept, through relationship marketing, to digital economy, being object of discussion both in academic literature and managerial practice. If it is a fact that the 4Ps marketing mix is a milestone of marketing theory, it is also true that the evolution of business contexts has created, in many fields, the need to review the "controllable factors" which form the marketing mix. The digital business represents the more recent of the business contexts and the one with the greater needs of differentiation of the mix. Throughout this evolutionary process, …
Behavioral and Neural Arguments of Motivational Influence on Decision Making During Uncertainty
2020
The scientific world is increasingly interested in motivation, primarily due to the suspected impact on decision-making abilities, particularly in uncertain conditions. To explore this plausible relationship, 28 healthy participants were included in the study and performed decision-making and motivational tasks while their neural activity was recorded. All participants performed the Iowa Gambling Task (IGT) and were split into two groups based on their score, one favorable group with 14 participants who performed advantageously and one undecided group with 14 participants who failed to develop the correct strategy on the IGT. In addition, all participants performed the Effort Expenditure fo…
Relación entre complejidad y dificultad en tareas con patrones lineales reiterativos en estudiantes de 5 años
2018
Una de las finalidades de la enseñanza de las matemáticas en Educación Infantil es fomentar el pensamiento lógico, la creatividad y la capacidad para resolver problemas de los estudiantes. Entre las actividades escolares propias de estas edades es habitual encontrar tareas de identificación y continuación de patrones lineales de repetición. Esta actividad puede ser estudiada desde un contexto de resolución de problemas en el que el estudiante debe discriminar la información superflua de aquella que le permite obtener la regla de generación de la serie y resolver la tarea. Diferentes variables como la longitud del núcleo de repetición, el número de descriptores, su naturaleza o la aparición …
