Children's Television Experience in Two Cultures

Research concerning children and television has concentrated more on their behaviour following viewing than on their personal experiences of this medium and the subjects are commonly American children from a distinctive television milieu. This study investigated first‐person reports of children from two rather different television cultures—US and West German (FRG). It was hypothesised that Americans would be more pro‐television, and thereby more dependent on television, more accepting of programmed violence and more fantasy‐involved in programme content; while experiencing less parental control/influence than West Germans. A sample of 93 FRG and 87 US children aged 10‐12 responded to a television‐viewing questionnaire of 34 items. The American children were significantly more pro‐television than the West Germans, and this was reflected in higher dependency and lower parental control scores. Responses to television fantasy and violence proved ambiguous, and no significant programme character preference differences were found. A principal components analysis of the American scores supported the intuitive item groupings.     

The Development of Selective Copying: Children's Learning From an Expert Versus Their Mother

This study tested the prediction that, with age, children should rely less on familiarity and more on expertise in their selective social learning. Experiment 1 (N = 50) found that 5‐ to 6‐year‐olds copied the technique their mother used to extract a prize from a novel puzzle box, in preference to both a stranger and an established expert. This bias occurred despite children acknowledging the expert model's superior capability. Experiment 2 (N = 50) demonstrated a shift in 7‐ to 8‐year‐olds toward copying the expert. Children aged 9–10 years did not copy according to a model bias. The findings of a follow‐up study (N = 30) confirmed that, instead, they prioritized their own—partially flawed—causal understanding of the puzzle box.     

Determinants of the half-turn with the ball in sub-elite youth soccer players

We explored the biomechanics of the 180° change-of-direction with the ball (half-turn) in soccer. We aimed at identifying movement strategies which enhance the players’ half-turning performance, by characterising technique kinematics and understanding the structure of biomechanical and anthropometrics variables. Ten Under-13 sub-elite male players were recorded with an optoelectronic motion analyser while performing a 5-m straight dribbling followed by a half-turn with the sole. Joints kinematics differences between faster and slower trials were found in support-side hip rotation, driving-side hip adduction, trunk flexion and rotation, and arms abduction. To unveil the data-set structure, a principal component (PC) analysis and a stepwise linear discriminant analysis were performed using 30 biomechanical parameters and four anthropometric variables for each trial. Seven retained PCs explained 79% of the overall variability, featuring combinations of original variables that help in understanding the factors facilitating fast half-turns: keeping short steps, minimising lateral and forward body movements, and centre-of-mass lowering, even with ample lower limbs ranges of motion (RoM); abducting the upper limbs while limiting trunk flexion and pelvic inclination RoM. Balance and task-constrained exercises may be proposed to improve this technique. Moreover, a quantitative knowledge of the movement structure could give coaches objective insights to better instruct young players.     

Education for sustainability within early childhood studies: collaboration and inquiry through projects with children

This paper considers an Action Research project which was implemented to establish a shared understanding of the term ‘Education for Sustainable development’ within the context of an Early Childhood Studies degree. Students engaged in projects with children and local early years’ providers, and the research aligns with previous work undertaken by Siraj-Blatchford, Smith, and Samuelsson (2010. Education for Sustainable Development in the Early Years. Organisation Mondiale Pour ?Education Prescolaire (OMEP)), which explored the role of education for sustainability in the field of Early Childhood Education. With the lingering and persistent preoccupation with testing, results and outcomes in early childhood education, compulsory school education and higher education the research aimed to capture the idea of the student as a change agent with opportunities to work with children as agents of change. The main findings lean towards participatory action research as an emancipatory reminder that research does not need to be a technical activity and the voices and actions of children, students and early childhood educators can be foregrounded in a way that validates authentic involvement by all participants.     

Simulation of small humanoid robots for soccer domain

In this paper, we illustrate the development of a realistic simulation of a humanoid robot model in a virtual environment using USARSim (Urban Search and Rescue Simulator). USARSim provides an accurate 3D simulation of a virtual environment with a detailed rendering and a realistic physics. Moreover, USARSim allows users to observe the virtual environment from different views. One of these is the egocentric view, which can simulate the camera mounted on the robot. The small humanoid robot presented in this work is Robovie-M, developed by VStone Ltd. (Japan). This robot is used by our team Artisti in the RobotCup soccer competitions.Reported experiments compare the behaviors of a real robot and of its virtual model, when controlled by the same control software to asses the possibility to faithfully simulate a robot with 22 degrees of freedom in USARSim. Moreover, we discuss the possibility to close the control loop of the robot in simulation, by simulating also the main robot sensor, i.e. the camera.The experiments show that USARSim, despite being a simple simulator based on a low cost computer game, provides an accurate enough simulation of the physics and a realistic rendering of the 3D scene enabling a faithful simulation of a small humanoid robot at low cost. Thus, one can entirely test the robot software modules in the simulation (namely: the motion control modules, the vision system modules and, by closing the robot control loop in simulation, the behavior and behavior-selection modules).     

What makes for a successful re-integration from a pupil referral unit to mainstream education? An applied research project

A qualitative research project was carried out in order to explore the views of Pupil Referral Unit (PRU) and mainstream school staff regarding the process of re-integration of secondary school age pupils from the PRU to mainstream school. The views of 11 PRU staff members, six mainstream staff members and a member of the Behaviour Support Service were sought through focus groups regarding the re-integration of pupils from the PRU to mainstream education. Thematic Analysis of the data suggested that effective re-integration is perceived to be most successful when particular factors at the child, family, school and systemic levels are in place, such as the child wanting to return to mainstream school, support from and engagement of parents and timely re-integration into a truly inclusive mainstream setting. Suggested developments to improve the process and practice of re-integration in the future were also identified. The implications of the research findings are discussed.     

Vascular architecture:is it a helpful histopathological biomarker for hepatocellular carcinoma?

Hepatocellular carcinoma(HCC) remains one of the major public health problems throughout the world.Although originally associated with tumorigenic processes,liver angiogenesis has also been observed in the context of different liver in-flammatory,fibrotic,and ischemic conditions.Here we investigate the fractal dimension as a quantitator of non-Euclidean two-dimensional vascular geometry in a series of paired specimens of primary HCC and surrounding non-tumoral tissue,and discuss why this parameter might provide additional information regarding cancer behavior.The application of fractal geometry to the measurement of liver vascularity and the availability of a computer-aided quantitative method can eliminate errors in visual interpretation,and make it possible to obtain closer-to-reality numerals that are compulsory for any measurement process.     

Co-construction of knowledge in tertiary online settings: an ecology of resources perspective

Tertiary education has seen a shift toward pedagogies that make use of social interaction. As part of the shift, teachers have considered re-framing their role in the teaching process, and giving more attention to ways in which knowledge construction amongst students can be supported. While many online technologies are well positioned to support interactivity between students, the use of these tools does not necessarily ensure that the social interaction is of a type that guarantees learning will take place. This paper employs an “ecology of resources” perspective (Luckin 10.1016/j.compedu.2007.09.018, 2008) to explore the experiences of teachers and selected students from three tertiary-level contexts as they engaged with interactive learning tasks mediated by asynchronous online technologies. The data presented in the study were generated primarily from accounts and semi-structured interviews, and presented teachers’ beliefs about how the learners could operate as knowledge resources for each other, while they themselves were somewhat ‘epistemically distant’. In contrast, the data suggest that the experiences of students and tutors were vastly different. The students represented themselves and others as inadequate resources, perceiving that the expertise to construct knowledge was not present in the student group. These observations highlight the importance of building resource-rich learning environments, enabling access to expert performances through blended settings, and nurturing a perception of capability between students.     

Behaviour support in secondary schools

Student voice and pupil empowerment projects are common in many mainstream schools. However, such initiatives are more challenging to implement in provision for students experiencing (social), emotional and behavioural difficulties (SEBD). As a consequence, they are less frequently attempted. This article reports one such attempt at an SEBD special school, where a student research group was formed to evaluate the school's behaviour policy. The students' views remind professionals of the need for consistency, positive relationships and communication underpinning behaviour management strategies. The article also reflects on a number of issues to consider when implementing such projects in special education contexts.
