The Last and Most Developed Naṣrid Palace in the Alhambra: The Alijares and Its Country Estate (Fourteenth Century)

The country estate (al-munya, almunia in Spanish) of the Alijares occupied grounds near the Alhambra and the Generalife, although it was higher up. It was constructed at the peak of the Na?rid dynasty's splendour, during the last stage of the reign of Mu?ammad V (r.1354–1359 / 1362–1391), after he had finished the Palace of the Lions.

The Alijares formed the last link in the chain in the stylistic development of the palaces of al-Andalus. When its founder decided on the features of the Alijares, he was in search of something that was completely innovative, as he had already undertaken work in the medinas of Granada and in the Alhambra that turned out to be a transformation of the architectural forms so far developed.

Life in the palace and the al-munya was cut short by sizeable earthquake in 1431, which coincided with a hard Castilian military campaign against the Kingdom of Granada. The consequences of the allegiance formed after the Na?rid defeat hindered the reconstruction of the Alijares, and so the royal buildings above the Royal Water Channel (Acequia Real) of the Alhambra were abandoned. Although time has erased many of the traces of the palace and its al-munya, we have extensive knowledge of its main architectural features, thanks to an analysis of all the available sources.     

Identity and Culture: theorising emergent environmentalism

This article critically examines the methodology and findings of the emergent environmentalism research project as reported in Environmental Education Research (EER), 4(4). We challenge both the ontological stance implicit in the research as well as its explicit epistemology. We argue for a wider theoretical underpinning to the research and specifically advocate the use of identity theories to explain personal and social phenomena. We also argue for the use of theoretical frameworks that empower rather than ‘capture’ cultural groups.     

The belief revision model: asymmetrical effects of noncontingency on human covariation learning

A noncontingent experience affects the subsequent detection of positive and negative contingencies between the same events. Experiments 1 and 2 showed that such preexposure can produce both an impairment in the detection of subsequent positive contingency and a facilitation of a negative one, independent of the level of contingency during the contingent phase. Experiment 3 raised difficulties for a model that assumes that associations to the context can explain this asymmetrical effect. Experiment 4 suggested that the different weights usually assigned to the different types of trials when computing the contingency between events can change as a result of a noncontingent experience with the same events. This change supports an account of the asymmetrical effect by a belief revision model based on a mechanism that updates the weights of the different trial types as a function of previous experience. More generally, the belief revision model is a statistical (i.e., nonassociative) model of learning that is capable of accounting for trial-order effects, which have long posed problems for statistical models.     

Antecedents of approach-avoidance goals in sport

We investigated antecedents of mastery-approach, mastery-avoidance, performance-approach, and performance-avoidance goals in sport. University athletes (n = 230) aged 18-25 years (mean 20.3 years, s = 1.5) completed measures of approach-avoidance goals, perceived parental motivational climate, perceived team motivational climate, perceived competence, and demographics. Multiple regression analyses revealed that mastery-approach goals were positively predicted by perceived competence, mastery team climate, learning/enjoyment parental climate, and gender, with males being higher on these goals than females. Mastery-avoidance goals were predicted positively by learning/enjoyment parental climate and negatively by gender, with females being higher on these goals than males. Performance-approach goals were positively predicted by perceived competence, performance team climate, and gender, with males being higher on these goals than females. Finally, performance-avoidance goals were predicted positively by worry-conducive parental climate. These findings suggest that a mastery or performance climate is related to whether athletes adopt a mastery or performance goal, whereas the perception of competence is associated with whether athletes adopt approach-focused goals. Gender should be considered in future examinations of the approach-avoidance achievement goals in sport.     

Reference values and improvement of aerodynamic drag in professional cyclists

The aims of this study were to measure the aerodynamic drag in professional cyclists, to obtain aerodynamic drag reference values in static and effort positions, to improve the cyclists' aerodynamic drag by modifying their position and cycle equipment, and to evaluate the advantages and disadvantages of these modifications. The study was performed in a wind tunnel with five professional cyclists. Four positions were assessed with a time-trial bike and one position with a standard racing bike. In all positions, aerodynamic drag and kinematic variables were recorded. The drag area for the time-trial bike was 31% higher in the effort than static position, and lower than for the standard racing bike. Changes in the cyclists' position decreased the aerodynamic drag by 14%. The aero-helmet was not favourable for all cyclists. The reliability of aerodynamic drag measures in the wind tunnel was high (r > 0.96, coefficient of variation < 2%). In conclusion, we measured and improved the aerodynamic drag in professional cyclists. Our results were better than those of other researchers who did not assess aerodynamic drag during effort at race pace and who employed different wheels. The efficiency of the aero-helmet, and the validity, reliability, and sensitivity of the wind tunnel and aerodynamic field testing were addressed.     

Goal orientations, motivational climate, and prosocial and antisocial behaviour in youth football: exploring their temporal stability and reciprocal relationships

In this study, we examined the temporal stability and reciprocal relationships among task and ego orientation, task- and ego-involving climates, and prosocial and antisocial behaviour in youth football. Male (n = 156) and female (n = 24) footballers (mean age 14.1 years, s = 1.8) completed questionnaires towards the beginning and end of a regular season. Questionnaires measured goal orientation, perceived motivational climate, and frequency of prosocial and antisocial behaviours. Structural equation modelling indicated moderate covariance stability between the beginning and end of the season. Subsequent analyses revealed a significant decrease only in perceptions of task-involving climate. In the cross-lagged analyses, prosocial behaviour at the beginning of the season positively predicted task-involving climate at the end of the season. Antisocial behaviour at the beginning of the season positively predicted both ego orientation and ego-involving climate at the end of the season and a reciprocal relationship was revealed whereby ego orientation at the beginning of the season positively predicted antisocial behaviour at the end of the season. Task orientation at the beginning of the season negatively predicted ego-involving climate at the end of the season. All cross-lagged relationships were weak. This exploratory study offers limited support for bi-directional relationships between personal, environmental, and behavioural variables but provides useful insight into the covariance stability, change, and interrelationships between motivational and moral constructs over a competitive season.     

Activity profile of top-class association football referees in relation to fitness-test performance and match standard

The aim of this study was to examine the kinematic activity profiles, cardiovascular responses and physical fitness of top-class football referees (n=11) during the FIFA Confederations Cup 2005. Computerised match-analyses (n=9) were performed with a two-dimensional photogrammetric video system, and the cardiovascular demand imposed on the referees (n=12) was measured using heart rate recordings. Total distance covered was 10,218, s=643 m of which 3531, s=510 m was covered at high intensities (>3.6 m.s(-1)). Both total distance covered (r2=0.59; P=0.02) and high-intensity activities (r2=0.44; P=0.05) were related to the distance covered by the ball in the same match. The referees ran at high speed 37% further (P=0.01) in the actual tournament than during under-17 top-level officiating. After the 5-min interval during which high-speed running peaked, in the following 5 min the performance was reduced by 19% (P=0.01) in relation to the mean of the game. Mean heart rate was 161, s=9 b.min(-1) (86, s=3% of maximal heart rate (HRmax)). Mean heart rate (expressed as percentage of HRmax) was related in part (r2=0.36; P<0.01) to the number of high-intensity activities performed in the same 5-min interval. The results of this study show that: (1) kinematic activity profiles of top-class referees can be influenced by the distance covered by the ball; (2) the amount of high-speed running (>5 m.s(-1)) best describes the physical performance of referees; (3) heart rate recording can be a useful tool to determine the most intense periods of a match and (4) the new fitness tests adopted by FIFA were poor predictors of match activities.
