This article adopts a microanalytic approach to examine storytelling as a co-construction by family members in a Cypriot-Australian family. Previous studies on family storytelling have focused on the various roles of family members in storytelling with a means of studying family socialization (Miller et al., 1990; Ochs & Taylor, 1992; Blum-Kulka, 1997). These studies used critical discourse analysis, socioculturel theories, performance and pragmatic approaches to storytelling. This article offers a distinctive approach to family storytelling by examining the discourse and social identities that family members display during the storytelling. The data originate in a study that involves interviews with three generations of Greek-Australian and Cypriot-Australian women regarding their relationships with each other. In this paper we investigate the contributions of the father and the daughters in the course of the mother's turn at storytelling. The first part of the analysis focuses on the husband's discourse identities as a contributor, initiator and elicitor of his wife's storytelling. During the storytelling we also observe the production and exchange of different social identities between the husband and the mother, such as the 'unwilling suitor', the 'embarrassed schoolgirl' or the 'forceful but teasing husband'. The second part describes how the daughters take part in their mother's storytelling, producing a variety of identities such as the 'impatient mother', the 'complaining', 'happy', or 'good' mothers and daughters. These investigations succinctly illustrate how narratives become a resource for members' 'display' and 'play' of identities. Copyright ©2002, John Benjamins B.V.

The play of children with autistic spectrum disorder (ASD) is a valuable medium for assessment and intervention, and its analysis has the potential to aid diagnosis. This study investigated spontaneous play behavior and play object preferences for 24 preschool children with ASD in a typical occupational therapy clinical environment. Play behavior was rated and choice of play object noted at 10-second intervals from a 15-minute video recording of unstructured play. Statistical analyses indicated that play behavior was consistent with descriptions in the literature. In addition, the children demonstrated clear preferences for play objects in the form of popular characters (e.g., Thomas the Tank Engine) and those with sensorimotor properties. We propose that the inclusion of preferred play objects in a clinical environment may increase intrinsic motivation to play, and thereby enhance assessment and intervention.

This study aimed to develop a practical method of estimating energy expenditure (EE) during tennis. Twenty-four elite female tennis players first completed a tennis-specific graded test in which five different intensity levels were applied randomly. Each intensity level was intended to simulate a game of singles tennis and comprised six 14 s periods of activity alternated with 20 s of active rest. Oxygen consumption (VO2) and heart rate (HR) were measured continuously and each player's rate of perceived exertion (RPE) was recorded at the end of each intensity level. Rate of energy expenditure (EEVO2) during the test was calculated using the sum of VO2 during play and the 'O-2 debt' during recovery, divided by the duration of the activity. There were significant individual linear relationships between EEVO2 and RPE, EEVO2 and HR, (rgreater than or equal to0.89 rgreater than or equal to0.93; p

The edification of the landscape in the scientific and social field, in speech as in the method, is taken in this study as a complex process, from which were developed relationships of dominance on the perception of space, which persist strongly consolidated, since the genesis of the conceptual practice till its actual praxis. Historically, the landscape studies took place slowly, immersed in many questions, in face of the multiplicity of meanings that the concept offers. In the psyche, the notion of landscape is present since a long time ago, as an unconscious human being practice, even before any ideological hypothesis formulation. However its materialization in the social conscious will come only from painting, and specially with the perspective, through the technicity of the view, at first wandering the infinity, now ordained in a frame‟. Since then, the landscape is perceived according to the order of the view, as the equivalent of nature and beauty, assuming at the same time, an important symbolic value, since it is linked to mnemonic and subjective processes that the being build with the territory. The domain on this space-cognitive experience, characteristic of the contemporary, consolidates in the social imaginary, building consensus on the landscape, whose aesthetic references make a cultural appeal, very pertinent to the actual capitalist dynamics of production the space worldwide, mainly of the spectacle and commodification of cities promoted by the city marketing. In Brazil, this consensual ideology of the landscape surpass the social imaginary and also dominates the political imaginary, whereas the main instrument for preserving the landscape, Decree-law 25, from November 30, 1937, and its limit to those of exceptional value or remarkable feature. The analysis of the processes for putting under governmental trust for inscription of goods by the landscape value, reveals the dominant, if not exclusive, adoption of selection criteria related to aesthetic aspects. Abstain, therefore, from what the nation considers patrimony , other landscapes that, besides not having, at first, remarkable aesthetic value, play a crucial role as an inheritance from ancestor relations between man and space and pre- existing condition for the same present and future relations. From this historical background, the research seeks to transfer into contemporaneity, the ideological analysis of the concept and its relation with the building of the landscape in the collective imaginary, in order to recognize, in current practices to landscape preservation, as much this genesis, rooted in aesthetics, remains strongly consolidated, feeding the current dynamics of consumption and commodification of the city. Therefore, as preliminary conclusion, one can state that the identification of landscapes of different value, especially aesthetic, maintains and intensify the treatment of the city as an object, a standard‟ commodity to be sold / traded on the world market, in detriment of its recognition as a dynamic process that, even though inserted in the global context, develops specificifities and peculiarities, inherent to the production of space, as Lefebvre preconizes, that is, to the production of life, social product , as characteristic, dissent generator

In sport there is a great need to obtain as much information as possible about the factors which affect the dynamics of play. This study uses sequential analysis and temporal patterns (T-patterns)to examine the evolution of defence (against an equal number of attackers)as used by the Spanish handball team at the Beijing 2008 Olympic Games. The aim is to help handball coaches (during their training and gathering of professional experience)to understand the importance of the structure of defensive systems. This can be achieved through observational processes that reveal the evolution and adaptation of these defensive systems according to different variables: the match score, the response of the opposing team and progress through the tournament.

In this work we investigate the population dynamics of cooperative hunting extending the McCann and Yodzis model for a three-species food chain system with a predator, a prey, and a resource species. The new model considers that a given fraction sigma of predators cooperates in prey's hunting, while the rest of the population 1-sigma hunts without cooperation. We use the theory of symbolic dynamics to study the topological entropy and the parameter space ordering of the kneading sequences associated with one-dimensional maps that reproduce significant aspects of the dynamics of the species under several degrees of cooperative hunting. Our model also allows us to investigate the so-called deterministic extinction via chaotic crisis and transient chaos in the framework of cooperative hunting. The symbolic sequences allow us to identify a critical boundary in the parameter spaces (K, C-0) and (K, sigma) which separates two scenarios: (i) all-species coexistence and (ii) predator's extinction via chaotic crisis. We show that the crisis value of the carrying capacity K-c decreases at increasing sigma, indicating that predator's populations with high degree of cooperative hunting are more sensitive to the chaotic crises. We also show that the control method of Dhamala and Lai [Phys. Rev. E 59, 1646 (1999)] can sustain the chaotic behavior after the crisis for systems with cooperative hunting. We finally analyze and quantify the inner structure of the target regions obtained with this control method for wider parameter values beyond the crisis, showing a power law dependence of the extinction transients on such critical parameters.

This work describes a methodology to extract symbolic rules from trained neural networks. In our approach, patterns on the network are codified using formulas on a Lukasiewicz logic. For this we take advantage of the fact that every connective in this multi-valued logic can be evaluated by a neuron in an artificial network having, by activation function the identity truncated to zero and one. This fact simplifies symbolic rule extraction and allows the easy injection of formulas into a network architecture. We trained this type of neural network using a back-propagation algorithm based on Levenderg-Marquardt algorithm, where in each learning iteration, we restricted the knowledge dissemination in the network structure. This makes the descriptive power of produced neural networks similar to the descriptive power of Lukasiewicz logic language, minimizing the information loss on the translation between connectionist and symbolic structures. To avoid redundance on the generated network, the method simplifies them in a pruning phase, using the "Optimal Brain Surgeon" algorithm. We tested this method on the task of finding the formula used on the generation of a given truth table. For real data tests, we selected the Mushrooms data set, available on the UCI Machine Learning Repository.

The main idea of the article is to consider the interdependence between Politics of Memory (as a type of narrating the Past) and Stereotyping. The author suggests that, in a time of information revolution, we are still constructing images of others on the basis of simplification, overestimation of association between features, and illusory correlations, instead of basing them on knowledge and personal contact. The Politics of Memory, national remembrance, and the historical consciousness play a significant role in these processes, because – as the author argues – they transform historically based 'symbolic analogies' into 'illusory correlations' between national identity and the behavior of its members. To support his theoretical investigation, the author presents results of his draft experiment and two case studies: (a) a social construction of images of neighbors based on Polish narrations about the Past; and (b) various processes of stereotyping based on the Remembrance of the Holocaust. All these considerations lead him to state that the Politics of Memory should be recognized as an influential source of commonly shared stereotypes on other cultures and nations.
