Corundum Anorthosites-Kyshtymites from the South Urals, Russia: A Combined Mineralogical, Geochemical, and U-Pb Zircon Geochronological Study
2019
Kyshtymites are the unique corundum-blue sapphire-bearing variety of anorthosites of debatable geological origin found in the Ilmenogorsky-Vishnevogorsky complex (IVC) in the South Urals, Russia. Their mineral association includes corundum-sapphire, plagioclase (An61&ndash
An integrated analytical approach to define the compositional and textural features of mortars used in the underwater archaeological site of castrum …
2019
This paper aims to carry out an archaeometric characterization of mortar samples taken from an underwater environment. The fishpond of the archaeological site of Castrum Novum (Santa Marinella, Rome, Italy) was chosen as a pilot site for experimentation. The masonry structures reached the maximum thickness at the apex of the fishpond (4.70 m) and consisted of a concrete conglomerate composed of slightly rough stones of medium size bound with non-hydraulic mortar. After sampling, for a complete characterization of selected mortar fragments, different and complementary techniques (stereomicroscopy, polarizing optical microscopy, and X-ray powder diffraction analysis) were carried out in order…
Continuous Improvement on Detailed Design Phase : A Process Perspective
2020
The construction project being studied is a government investment related to the relocation of a biomedical institute delivering research-based knowledge and contingency support in the fields of animal health, fish health and food safety. The project covers a total of 63,000 square meters distributed over 10 buildings with a very high degree of complexity. The design alone has required 1 million hours, which relates to a client cost of about 100 million Euro. The purpose of this paper is to study the applied methodology for managing the detailed design to identify lessons learned from the project. The theory underlying the study is inspired by lean design management and design theory linked…
Intercultural Communication and its Challenges Within the International Virtual Project Team
2019
With the advance of technology, face-to-face intercultural communication moves into the online virtual environment via electronic tools such as audio-video conferencing, email, messenger chat, platforms, groups, thus distances between individuals from different cultures are reduced and the exchange of information takes place within a few seconds. Cultural differences should not be a barrier to communication but an opportunity for development. International virtual project teams (IVPTs) can benefit from cultural diversity and effective intercultural communication, because it can enhance creativity and innovation within the project team, while at the same time team members are enriched by acq…
Optimizing artificial neural networks for the evaluation of asphalt pavement structural performance
2019
Artificial Neural Networks represent useful tools for several engineering issues. Although they were adopted in several pavement-engineering problems for performance evaluation, their application on pavement structural performance evaluation appears to be remarkable. It is conceivable that defining a proper Artificial Neural Network for estimating structural performance in asphalt pavements from measurements performed through quick and economic surveys produces significant savings for road agencies and improves maintenance planning. However, the architecture of such an Artificial Neural Network must be optimised, to improve the final accuracy and provide a reliable technique for enriching d…
Penyagolosa Trails: From Ancestral Roads to Sustainable Ultra-Trail Race, between Spirituality, Nature, and Sports. A Case of Study
2019
[EN] The organization of an open-air sporting event involves a series of challenges. People are drawn by the desire to do sport, preferably in close contact with nature, so as to complement healthy lifestyles, and in search of air purity. Sporting organizations are increasingly searching for new locations that do not only attract athletes, but spectators and companions too. Races in natural parks provide the additional benefit of doing sport in a unique space, usually a transmitter of simplicity, pure air, and tranquillity. Organizing a mountain race in a natural park implies some issues. These are areas of great environmental richness that must be protected. Natural parks are places of ind…
The Influence of Emotion in the Management of Amateur Football Organizations.
2020
This article is oriented to the analysis of organisational and emotional variables in amateur sporting organizations. The general objective is to analyse the influence of organisational variables such as service quality, transactional leadership, and transformational leadership and emotional variables such as affective commitment, emotional attachment investment and emotional attachment dividend to predict the credibility that members of amateur sporting organisations perceive, as well as their degree of identification and loyalty. The opinions of 203 members of Chilean amateur football teams, (169 men and 34 women, with ages between 18 and 68 years (Mean=32.75 years, DT= 9.92) have been an…
Who Punishes? The Status of the Punishers Affects the Perceived Success of, and Indirect Benefits From, “Moralistic” Punishment
2016
“Moralistic” punishment of free riders can provide a beneficial reputation, but the immediate behavior is costly to the punisher. In Study 1, we investigated whether variation in status would be perceived to offset or mitigate the costs of punishment. One hundred and nineteen participants were presented with a vignette describing a punishment scenario. Participants predicted whether punishment would occur, how successful it would be, and indicated their attitude to the punisher. Participants believed only intervention by a high-status (HS) individual would be successful and that low-status (LS) individuals would not intervene at all. HS individuals predicted to punish successfully were seen…
Which Factors Modulate Letter Position Coding in Pre-literate Children?
2021
One of the central landmarks of learning to read is the emergence of orthographic processing (i.e., the encoding of letter identity and letter order): it constitutes the necessary link between the low-level stages of visual processing and the higher-level processing of words. Regarding the processing of letter position, many experiments have shown worse performance in various tasks for the transposed-letter pair judge-JUDGE than for the orthographic control jupte-JUDGE. Importantly, 4-y.o. pre-literate children also show letter transposition effects in a same-different task: TZ-ZT is more error-prone than TZ-PH. Here, we examined whether this effect with pre-literate children is related to …
¿Influye la Retroalimentación Correctiva en el Uso de la Retroalimentación Elaborada en un Entorno Digital?
2019
Los entornos digitales permiten proporcionar retroalimentación correctiva de verificación de respuestas (KR: correcto/incorrecto) o de respuesta correcta (KCR: la respuesta correcta es X), junto con retroalimentación elaborada (EF: explicaciones). Es frecuente asumir que los estudiantes procesan la EF, aunque investigaciones recientes demuestran que eso no siempre es así, debido probablemente a la retroalimentación correctiva proporcionada junto con la EF. El objetivo de este trabajo es analizar la decisión voluntaria de acceder a EF en función de la retroalimentación KR y KCR recibida inmediatamente tras responder preguntas de un texto de ciencias. Estudiantes de secundaria recibieron retr…
