Simple Forms of Image in Art History / Las formas simples de la imagen en la Historia del Arte

El estudio del arte prehistórico ha estado condicionado por las teorías acerca de la mente primitiva, el pensamiento prelógico o el inconsciente psicoanalítico. En este artículo, los autores desarrollan un nuevo método analítico en el que parten del concepto de las formas simples. La actividad artística comienza con el instinto lúdico, la búsqueda del ritmo y la simetría y la necesidad de "mímesis" o imitación. La expresión de las emociones, sentimientos o ideas puede acompañar o no a estas necesidades primarias. Este método se aplica a cuatro ejemplos: el desfile de los soldados, el carro de guerra, la cerámica decorada de Cnossos y los petroglifos de un pueblo de la selva amazónica.Palabras claveArte prehistórico, formas simples, símbolo, desfile de soldados, carro de guerra, decoración cerámica, petroglifos.AbstractThe study of Prehistoric art has been conditioned by the theories of primitive mind, prelogical thought or psychoanalytical unconscious.

Influence of Emotional Intelligence, Motivation and Resilience on Academic Performance and the Adoption of Healthy Lifestyle Habits among Adolescents

Included among the basic objectives of Physical Education (PE) classes is the consolidation of habits of a healthy lifestyle among adolescents. However, the main studies in this field have focused on cognitive aspects related to students during these classes, yet they ignore the role that emotions can play in the adoption of future habits. Objectives: To analyze how emotions (emotional intelligence and emotional state) can influence the resilience and motivation of adolescents, as well as academic performance and adoption of healthy lifestyle habits. Methodology: 615 secondary school students between the ages of 14 and 19 participated (M = 16.02; SD = 1.57) in the study. A structural equations model was developed using the main variables and by applying some of the principles of Self-Determination Theory. The results show that emotional intelligence is positively related to positive emotions and negatively related to negative emotions. Positive emotions positively predict both self-motivation towards physical education classes and resilience. Resilience positively predicts self-motivation. Finally, self-motivation acts as a predictor of both academic performance and regular participation in physical activity. Conclusions: This study successfully shows the importance of focusing on emotions in PE classes inasmuch as emotion increases the tendency to get good grades and maintain active lifestyle habits. In this sense, focusing on the emotions of students in PE could prove quite beneficial

Efficient Implementation on Low-Cost SoC-FPGAs of TLSv1.2 Protocol with ECC_AES Support for Secure IoT Coordinators

Security management for IoT applications is a critical research field, especially when taking into account the performance variation over the very different IoT devices. In this paper, we present high-performance client/server coordinators on low-cost SoC-FPGA devices for secure IoT data collection. Security is ensured by using the Transport Layer Security (TLS) protocol based on the TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256 cipher suite. The hardware architecture of the proposed coordinators is based on SW/HW co-design, implementing within the hardware accelerator core Elliptic Curve Scalar Multiplication (ECSM), which is the core operation of Elliptic Curve Cryptosystems (ECC). Meanwhile, the control of the overall TLS scheme is performed in software by an ARM Cortex-A9 microprocessor. In fact, the implementation of the ECC accelerator core around an ARM microprocessor allows not only the improvement of ECSM execution but also the performance enhancement of the overall cryptosystem. The integration of the ARM processor enables to exploit the possibility of embedded Linux features for high system flexibility. As a result, the proposed ECC accelerator requires limited area, with only 3395 LUTs on the Zynq device used to perform high-speed, 233-bit ECSMs in 413 µs, with a 50 MHz clock. Moreover, the generation of a 384-bit TLS handshake secret key between client and server coordinators requires 67.5 ms on a low cost Zynq 7Z007S device

Scoring coordination patterns in basketball international championships of national teams

The performance of two basketball teams can be analysed by exploring their different scoring dynamics on the basis of the two time series representing the scoring process of each team throughout the game. Existing studies following this approach focused mainly on regular season and playoff games in different basketball leagues. The aim of this study was to conduct this type of analysis on games of National Teams championships, focusing specifically on final round close games, as those in which medals are decided and teams perform in a very similar level. The study considers the final round games (i.e. semi-finals games, third-place game and final game) of the main men's professional basketball International Championships of National Teams (i.e. European Championships, World Championships and Olympic Games) played during the period 2005-2013. Different methods of time series analysis were used (i.e. autocorrelation and cross-correlation functions, double backward moving averages, Hilbert transform). The results revealed an increasing scoring coordination pattern between the teams as the games unfolded, showing extremely high coordinated behaviours in the 3rd and 4th quarters (i.e. similar scoring streaks by the two teams; back-and-forth scoring patterns). This suggests that are the first two quarters of the games those leading to major fluctuations on the scoreboard (i.e. game periods in which one team's scoring performance is very successful whilst the other team's is not). This study may be matter of interest to coaches and performance analysts in the field of basketball, providing practical information for specific games preparations in International Championships of National Teams.El rendimiento de dos equipos de baloncesto se puede analizar mediante la exploración de sus diferentes dinámicas de anotación sobre la base de las dos series temporales que representan el proceso anotador de cada equipo durante todo el partido. Los estudios existentes siguiendo este enfoque se han centrado principalmente en partidos de temporada regular y de playoff en diferentes ligas de baloncesto. El objetivo de este estudio fue llevar a cabo este tipo de análisis en partidos de campeonatos de selecciones nacionales, centrándose específicamente en los partidos ajustados de las rondas finales, como aquellos en los que se deciden las medallas y en los que los equipos desempeñan en un nivel muy similar. El estudio considera los partidos de las rondas finales (semifinales, tercer y cuarto puesto, y final) de los principales campeonatos internacionales de baloncesto de selecciones nacionales en categoría masculina (Campeonatos Europeos, Campeonatos del Mundo y Juegos Olímpicos) disputados durante el período 2005-2013. Se utilizaron diferentes métodos de análisis de series temporales (funciones de autocorrelación y correlación cruzada, doble media móvil, transformada de Hilbert). Los resultados revelaron un patrón creciente de coordinación anotadora entre los equipos a medida que los partidos avanzaban, mostrando patrones de coordinación extremadamente altos en el tercer y último cuarto (rachas de anotación similares para los dos equipos, patrones de anotación de ida y vuelta). Esto sugiere que son los dos primeros cuartos de los partidos aquellos que conducen a mayores fluctuaciones en el marcador (períodos de juego en los que el rendimiento anotador de un equipo es muy exitoso, mientras que el del otro equipo no lo es). Este estudio puede ser de interés para los entrenadores y analistas de rendimiento en baloncesto, proporcionando información práctica para la preparación específica de partidos en los campeonatos internacionales de selecciones nacionales

Energy integration of high pressure processes using gas turbines and internal combustion engines

High pressure processes (e.g. sustainable hydrothermal manufacturing of nanomaterials [1], supercritical water oxidation (SCWO) [2] and biomass hydrolysis [3]) require high operational conditions. Water at high pressure and temperature conditions improves kinetic, selectivity and efficiency of these processes but entail high-energy operational expenditure. Use of fluids at high operational conditions makes necessary to supply heat of high quality, as well as power. Because of this, it is necessary to study reasonable solutions for energy recovery and integration in order to achieve the energy self-sufficiency of the process and, if possible, the net power production and with a viable efficiency [4]. In this work, the energy integration of supercritical water oxidation process is being studied. One solution that has been recently proposed is the integration of supercritical processes with energy production in cogeneration or Combined Heat and Power (CHP) cycles. Cogeneration is defined as the simultaneous production of various forms of energy – being the most frequent heat and shaft work, i.e., power – from one power source. The implementation of CHP processes is often joined to the use of gas turbines (GT) [3, 5]. SCWO process produces a high pressure reactor outlet stream, being these mainly composed of water, nitrogen and carbon dioxide and can be thermally integrated if there is a necessity of heat in other parts of the process. At the same time, it is possible to use this effluent to implement a steam injection in the gas turbine, which will improve the efficiency of the global process. This mechanism links the process of SCWO with the cogeneration process (Fig. 1). Steam injection is a technique which can increase the ability of a plant to generate extra power without burning extra fuel and requiring moderate capital investment. In its most basic form, steam injection works by increasing the global mass flow rate through the gas turbine without increasing the mass of air compressed.

Digital Identities of Young People from the South of Spain: An Online Sexual Differentiation

Through a mixed methodological approach, we want to know how adolescents aged between 14 and 16 years from the south of Spain express and identify themselves on social networks, with respect to their sex. As such differences can determine gender inequality, we will analyse differences between females and males regarding the expression of identity on social networks. Analysis of obtained results demonstrates that many relevant attributes still emerge such as the socio-cultural representation of gender as sex in social networks. Differences emerged between the identity expressions of females and males which can generate inequalities favouring females and males. This implies a series of repercussions and, ultimately, defines the so-called digital gender divide. Taking into account these results we could intervene in the population of children to carry out prevention activities focused on social network
