‘That is like a 24 hours-day tournament!’: using social media to further an authentic sport experience within sport education

Several studies demonstrate that Sport Education supports the development of an authentic experience of sport. Social media has the potential to further the development of an authentic sport experience since it is a key aspect of contemporary sport culture and can be a space for individuals to interact during the Sport Education. Yet the evidence-base on the use of social media within Sport Education is limited. The purpose of this study was to explore how social media supports the development of an authentic sport experience within Sport Education. The context of this study was within a female recreational community sport futsal club. Players engaged with Sport Education as a focus for their sessions for 13 weeks. The Sport Education season embedded the six key features. During the Sport Education season, players interacted with each other through Facebook. Data were generated from; (1) researcher/player field journal, (2) Facebook posts and (3) post-season player interviews. Data analysis involved inductive, constant comparison and member-checking methods. Results showed that players’ uses of Facebook supported the development of an authentic sport experience. Players’ uses of Facebook strengthened the development of three key Sport Education features; affiliation, festivity and season. Based on the limited amount of research on the impact of social media within Sport Education and community sport, future studies should continue to examine the effectiveness of social media as an interactional tool to enhance the development of an authentic sport experience.     

Spacecraft formation flying reconfiguration with extended and impulsive maneuvers

This paper presents the control solutions to the spacecraft formation reconfiguration problem when impulsive or extended maneuvers are considered, and the reference orbit is circular. The proposed approach for the derivation of the control solutions is based on the inversion of the linearized equations of relative motion parameterized using the mean relative orbit elements. The use of mean relative orbit elements eases the inclusion of perturbing accelerations, such as the Earth’s oblateness effects, and offers an immediate insight into the relative motion geometry. Several maneuvering schemes of practical operational relevance are considered and the performance of the derived impulsive and piecewise continuous control solutions are investigated through the numerical propagation of the nonlinear relative dynamics. Finally, the benefits of the new extended maneuvers strategies are assessed through a comparison with the corresponding impulsive one.     

A study on a set of drawings by Parmigianino: integration of art-historical analysis with imaging spectroscopy

Due to the extreme fragility of paper-based artefacts, few techniques are available for scientific investigation and characterisation of ancient drawings or paper-based artefacts. Image reflectance spectroscopy represents an almost unique tool for scientific analysis on precious drawings, for which even micro-invasive techniques of analysis cannot be used. Indeed, beside the high fragility of the support, drawings and graphical works are typically characterised by a very limited number of artistic materials, which in principle could give information on the work of art. In this paper an interdisciplinary study on a set of drawings by Parmigianino (1503–1540), selected from the collection of the Uffizi Gallery in Florence, is presented. Non-invasive measurements of image spectroscopy (IS) have been employed to support the work of art-historians in the critical re-examination and interpretation of the graphical work of the artist. The multispectral analysis has been carried out over the extended spectral region (400–1700 nm), in order to provide simultaneous indications both on the pictorial materials and on possibly underlying hatches. The data processing has been performed by means of Principal Component Analysis (PCA) and the elaboration of each case has been addressed to specifically respond to questions related to the art-historical problem.     

Process-Oriented Guided Inquiry Learning (POGIL) as a Culturally Relevant Pedagogy (CRP) in Qatar: a Perspective from Grade 10 Chemistry Classes

Research in Science Education - Educational reforms in Qatar have seen the implementation of inquiry-based learning and other student-centred pedagogies. However, there have been few efforts to...     

Stimulus control of immunization against chronic learned helplessness

Two experiments investigated the effectiveness of multiple (five) sessions of signaled eseapable-shock pretraining in preventing (immunizing against) the shack-escape impairment produced by an equal number of sessions of signaled inescapable shock. In Experiment 1, rats were exposed to 50 pairings per session of a white-noise stimulus with escapable shock during the immunization phase. Subsequently, they were exposed to 50 pairings per session of a different (houselight) stimulus with inescapable shock. Shock-escape performance in a shuttlebox test with constant illumination revealed no evidence of immunization relative to the performance of rats given five prior sessions of light-signaled inescapable shock only. Experiment 2 was identical in all respects to Experiment 1, except that both the escapable- and the inescapable-shock phases for animals in the immunization treatment group involved the same stimulus (houseüght) as a shock signal. Under these circumstances, the prior escapable-shock training significantly reduced the shuttle-box escape deficit engendered by chronic exposure to signaled inescapable shock; performance in the shuttle-box was not reliably different from that of rats exposed to signaled escapable shock alone. These findings suggest that, under chronic conditions, the development of stimulus control using Pavlovian conditioning procedures may serve to modulate the normally prophylactic influence on later shock-escape acquisition of serial exposure to escapable and inescapable shocks.     

A systematic literature review on intangible assets and open innovation

Despite the growing interest, Open Innovation (OI) in Intangible Assets (IAs) research is still fragmented and displays a limited contextual focus. This paper aims to provide a clearer view of these issues and represents a first step toward filling such research gap. A systematic literature review and a synthesis of high-quality contributions with a focus on a general overview of research on OI and IAs in OI processes have been carried out. By critically evaluating the current body of literature and definitions, we have moved a step further toward comprehending the multiple facets of existing research and highlight several promising areas for future development. In particular, we have analyzed the role of IAs in OI practices by selecting a synthesis and a critical review of their different exploitations. We have combined multiple algorithms to produce a clear topical taxonomy of the multiple strands of research lying at the interface of OI and IAs.     

Social robots as cultural objects: The sixth dimension of dynamicity?

We investigate youths' conceptualization of social robots. Informed by Schudson's theory of the potency of the cultural object, we conducted two studies. The first study centered on essays on social robots written by bachelor's and master's students. The second study centered on prototypes of social robots built by small groups comprised of same students. The essays and prototypes were content analyzed. The results confirm that social robots embody all five dimensions that characterize cultural objects. However, to fully understand this peculiar cultural object, another dimension needs to be introduced: dynamicity.
