Revisión del catastro romano de Illici (Elche)

En el presente trabajo se ha realizado un estudio del catastro romano del Ager de Illici (Elche), analizando su incidencia en el paisaje, su importancia histórica así como en que medida se ha conservado hasta nuestros días. Además este estudio ha permitido experimentar una metodología de trabajo dirigida al análisis rápido y sistemático de la morfología histórica del territorio en relación a otros elementos del paisaje, que ha permitido evaluar el potencial arqueológico de la zona. El análisis arqueomorfológico del Llano de Elche, junto al estudio metrológico y a la red viaria, han demostrado la existencia en esta zona de una ordenación de carácter ortogonal que presenta una orientación de 7,50 respecto al N geográfico y que responde a un módulo de 710 metros de lado, que es compatible a una centuriatio romana.

An approach to costs and energy consumption in private urban Spanish Mediterranean landscapes from a simplified model in sprinkle irrigation

The number of private gardens has increased in recent years, creating a more pleasant urban model, but not without having an environmental impact, including increased energy consumption, which is the focus of this study. The estimation of costs and energy consumption for the generic typology of private urban gardens is based on two simplifying assumptions: square geometry with surface areas from 25 to 500 m2 and hydraulic design with a single pipe. In total, eight sprinkler models have been considered, along with their possible working pressures, and 31 pumping units grouped into 5 series that adequately cover the range of required flow rates and pressures, resultin in 495 hydraulic designs repeated for two climatically different locations in the Spanish Mediterranean area (Girona and Elche). Mean total irrigation costs for the locality with lower water needs (Girona) and greater needs (Elche) were € 2,974 ha-¹ yr-¹ and € 3,383 ha-¹ yr-¹, respectively. Energy costs accounted for 11.4% of the total cost for the first location, and 23.0% for the second. While a suitable choice of the hydraulic elements of the setup is essential, as it may provide average energy savings of 77%, due to the low energy cost in relation to the cost of installation, the potential energy savings do not constitute a significant incentive for the irrigation system design. The low efficiency of the pumping units used in this type of garden is the biggest obstacle and constraint to achieving a high quality energy solution

Diferències en l'estil de joc ofensiu entre un equip consolidat a la 1a divisió i un equip d'ascens recent

L’objectiu del següent treball és buscar les diferències en l’estil de joc ofensiu (en els gols aconseguits) entre un equip consolidat a la 1a divisió espanyola (F.C Barcelona) i un equip d’ascens recent (Elx C.F). Per aconseguir-ho, s’analitzen els gols a favor per part dels dos equips durant les primeres 25 jornades de lliga 2013/2014. A través d’un full d’observació i tangent en compte totes les seves categories, es classifiquen cada un dels gols segons l’estil de joc ofensiu al qual pertany (Joc Combinatiu, Joc Directe o Joc Contraatac). Els resultats obtinguts demostren com existeixen diferències significatives en la utilització dels diferents estils de joc entre els dos equips. A més també es mostren diferències rellevants pel que fa al nombre total de gols aconseguits, en la presència d’una regularitat temporal (durant les 25 jornades) d’utilització d’un estil o altre i en la relació temporal (durant el partit) dels gols aconseguits entre els dos equips analitzats.

Risk perception and stages of smoking acquisition = Percepción de riesgo y etapas de iniciación en el consumo de tabaco

The purpose of this descriptive survey was to investigate the risk perceptions of smoking in a sample of 1,510 Spanish adolescents(49.1% males; mean age = 14.03; SD = 1.28). In addition, the present research categorised adolescents into one of the fourstages of smoking acquisition, as described by the Transtheoretical Model of Change (TMC): Precontemplation (notthinking about trying smoking in the next 6 months), Contemplation (thinking about trying smoking in the next 6 months), Preparation (thinking about starting smoking in the next 30 days) and Action (smokers), by gender and age. The results showed that age and risk perceptions are important variables in the progression through the stages of change towards regular tobacco consumption (Action stage). These results clearly demonstrate the importance of starting antismoking campaigns at an early age to prevent smoking acquisition or the thought of starting in the near future. These findings also highlight the need to continuously remind adolescents about the negative consequences of smoking
