Research on the machining process modeling of a rotational mold using CAM applications
2021
Rotational molding is a unique process, with a high growth rate, which allows the use of geometries and materials adapted to particular needs. It is superior to other manufacturing methods in terms of low cost, break-even point and size of parts that can be manufactured. Rotational molding products are often a substitute, with a lower mass, for traditionally used materials. In this scientific paper it is analyzed the recent literature related to the field of rotational molding processes. It also addresses the issue of processing a rotational mold, with the main purpose of optimizing the cutting regime. In this context, it is highlighted the way of processing the surface of the outer mold ba…
Crisis Communication Competence in Co-Producing Safety with Citizen Groups
2016
The aim of this article is to explore interpersonal communication competence needed by crisis communication and management experts when co-operating with citizen groups in response to emergencies. Moreover, the purpose is to understand how response organizations can further develop this crisis communication competence and so contribute to the functioning of response networks. The research task is approached qualitatively by eliciting crisis communication and management experts’ (n = 33) perceptions of the interpersonal communication competence response organizations needs when co-operating with citizen groups. The data were gathered via an international online questionnaire using a method r…
The Concordance between Teachers’ and Parents’ Perceptions of School Transition Practices: A Solid Base for the Future
2015
This study focuses on parents’ and teachers’ perceptions of practices aimed at easing the transition to formal schooling (e.g., familiarization with the school, discussions about the school entrants). A total of 230 preschool teachers, 131 elementary school teachers, and 2,662 mothers and fathers filled in a questionnaire containing items on how important they considered different preschool-school transition practices. The participants considered the various transition practices to be at least somewhat important. On average, familiarization with the school was considered to be most important, whereas teacher co-operation and joint writing of curricula were considered to be least important. …
Questions raised in science education : a Colombian-Spanish comparative study
2016
RESUMEN: La formulación de preguntas es un potente recurso para el aprendizaje de las ciencias. El objetivo del presente trabajo fue evaluar el desarrollo de la competencia metacognitiva por medio de la formulación de preguntas. En este estudio se usaron dos dispositivos experimentales de ciencias con un comportamiento inesperado. Se pidió a los participantes realizar preguntas destinadas a comprender su funcionamiento. La evaluación contrastó el desempeño de estudiantes colombianos con estudiantes españoles equivalentes. Los resultados mostraron que los colombianos formulan significativamente más preguntas en general, y más preguntas de alta calidad, que los estudiantes españoles. Se concl…
8.4GHz VLBI observations of SN2004et in NGC6946
2007
We report on 8.4GHz Very Long Baseline Interferometry (VLBI) observations of the type II-P supernova SN2004et in the spiral galaxy NGC 6946, made on 20 February 2005 (151 days after explosion). The Very Large Array (VLA) flux density was 1.23$\pm$0.07 mJy, corresponding to an isotropic luminosity at 8.4GHz of (4.45$\pm$0.3)$\times10^{25}$ erg s$^{-1}$ Hz$^{-1}$ and a brightness temperature of (1.3$\pm$0.3)$\times10^{8}$ K. We also provide an improved source position, accurate to about 0.5 mas in each coordinate. The VLBI image shows a clear asymmetry. From model fitting of the size of the radio emission, we estimate a minimum expansion velocity of 15,700$\pm$2,000 km s$^{-1}$. This velocity…
Are maximizers more normative decision-makers? An experimental investigation of maximizers' susceptibility to cognitive biases
2021
Abstract The present study tested the hypothesis that maximizers – people who routinely seek to make optimal decisions rather than quickly settling for an acceptable one – are less susceptible to cognitive biases. Experiment 1 showed that high maximizers are less swayed by irrelevant differences in the framing of a decision-making scenario than are low maximizers. Experiment 2 confirmed that maximizers are also less likely to neglect important base rate information when making decisions. Experiment 3 showed that maximizers are less likely to stick with a bad plan in which they have already invested (the sunk-cost bias) and therefore are quicker to switch to a more attractive alternative pla…
Enseñando música en inglés: un modelo de enseñanza basada en contenidos en educación secundaria obligatoria
2018
Over the past few years, there has been a growing interest in the teaching and learning of several languages in an attempt to generate multilingual education opportunities, particularly in Europe. In response to the demands of our globalized society, Content-Based Instruction (CBI), which has also been referred to as “immersion and Content and Language Integrated Learning (CLIL) programs,” emerged as a teaching approach that combines the learning of curricular contents and the communicative competence in the target language. This study was carried out at a public high school set in a Spanish bilingual community, where music is taught through a CLIL approach in English class. The purpose of …
Effectiveness of a creative physical education intervention on elementary school students’ leisure-time physical activity motivation and overall phys…
2018
This study investigated the effectiveness of a creative physical education (CPE) intervention on students’ perceptions of motivational climate in physical education (PE), leisure-time physical activity (PA) motivation, and overall PA. A sample of 382 fourth to sixth grade students ( Mage= 10.87[.93]) from two elementary schools were assigned to the CPE intervention ( n = 196; Mage= 10.84[.95]) and control ‘PE-as-usual’ ( n = 186; Mage= 10.90[.90]) groups. Students’ perceived task- and ego-supportive climate in PE, leisure-time PA motivation, and overall PA were measured before and after the one-year intervention. Analyses of covariance and path analyses were implemented to test the effectiv…
GraphoGame – a catalyst for multi-level promotion of literacy in diverse contexts
2015
GraphoGame (GG) is originally a technology-based intervention method for supporting children with reading difficulties. It is now known that children who face problems in reading acquisition have difficulties in learning to differentiate and manipulate speech sounds and consequently, in connecting these sounds to corresponding letters. GG was developed to provide intensive training in matching speech sounds and larger units of speech to their written counterparts. GG has been shown to benefit children with reading difficulties and the game is now available for all Finnish school children for literacy support. Presently millions of children in Africa fail to learn to read despite years of pr…
Project Education and Adams’ Theory of Equity
2020
This work-in-progress paper in research category is concerned with students’ perceptions of justice in software engineering group projects. Taking a directed content analysis approach, the aim is to analyze the relevance of Adams’ theory of Equity for small-group project education. The analysis was applied to the data collected from a third-year project course in which students encounter an open-ended group assignment. The results indicate that the theory can serve as a useful framework that helps teachers to identify justice-related issues in project courses. On the other hand, it was concluded that special carefulness is advisable considering the simplicity of the theory. peerReviewed
