Politicians’ perspective on the community-related impacts of major sports events – a case study for Innsbruck-Tyrol

While scholarly attention with respect to the social impacts of sports events has increased in recent years, there is still little research discussing the wide-ranging community-related impacts stemming particularly from major sports events. Local political leaders, as (elected) representatives of the community, are important stakeholders within this context and face the challenge of balancing diverse interests in the implementation of major sports events. The purpose of this study is to assess the importance politicians attribute to event impacts that create sustainable outcomes for residents living in a host city. Based on a content analysis, a list of general event impacts (outputs and legacies) produced by major sports events was created and subsequently discussed with scholars and experts in the field to classify the criteria as community relevant or not. A final number of 56 criteria (34 of which are considered community relevant) was then used in the assessment of the politicians’ (representing either the State of Tyrol or the City of Innsbruck) attitude towards these impacts. The findings of the study indicate that, though aware of community interests, politicians nevertheless prioritize economic and touristic benefits for the host city/region such as place marketing. Moreover, politicians seem to have a better understanding of tangible impacts (e.g. infrastructure), underestimating the important intangible impacts (e.g. voluntariness) closely related to community issues. Thus, the research in hand outlines the need to sensitize governments to community interests when planning and implementing major sports events.     

Analysis of the distances covered and technical actions performed by professional tennis players during official matches

The purpose of this study was to analyse the physical and technical performances of professional tennis players during official matches. The trajectories of eight players were obtained during matches, using an automatic tracking method. The distances covered and technical performances were analysed for the first and second sets. The athletes covered (mean ± standard deviation) a total of 1702.4 ± 448.2 m in the first set, 1457.6 ± 678.1 m in the second set and 3160.0 ± 880.1 in the entire match. No differences were found between the sets for the physical variables (lateral and forward displacements, distance covered per rally, per game and per set, and the percentage of time spent in each range of velocity). However, the distances covered by the athletes during the rallies in which they were serving (median = 5.2; interquartile range (IQR) = 6.7 m) were statistically smaller than when they were returning (median = 6.2; IQR = 7.7 m). Forehand ground stroke proficiency decreased from the first (mean ± standard deviation: 75.2 ± 4.11%) to the second set (mean ± standard deviation = 65.5 ± 14.3%). In conclusion, tennis players did not present reduced physical performance from the first to the second set.     

Pre-service Physics Teachers and Conceptual Difficulties on Temperature and Heat

In this article the ‘lesson preparation method’ was used to investigate pre-service teachers’ pedagogical content knowledge, in particular their knowledge of pupils’ conceptual difficulties on temperature and heat. A relation is found between the conceptual difficulties pre-service teachers expect their pupils to have and the conceptual difficulties they themselves have or have had. The discussion considers what pedagogical content knowledge teacher educators should include in the initial or inservice teacher education curriculum.     

Promoting digital citizenship in first-year students: Framing information literacy as a tool to help peers

This article explores the creation and implementation of a high-impact, hands-on assignment that both challenges and transforms students' perception of the power of information. The author created a web-based project in which students designed, organized, and promoted their own web portal for peers who were struggling with substance abuse addiction. In order to create buy-in from the students, the assignment's purpose centered on the concept of digital citizenship. The idea behind this concept is to encourage students to use information ethically and to help their fellow digital citizens find and use information ethically as well. In realizing the power of credible, useful information, the project aimed to encourage students to use this power to help their peers who may be struggling. Once the students demonstrated a firm understanding of information literacy, the assignment provided the challenge to put their abilities to practice in student-led small groups that were each in charge of a section of the website. The structure of the class mirrored a workplace environment where the teams set deadlines that were approved by group vote. In the end, each of the students had a hand in creating an open access website that included information that could help their peers in the “real world.”     

Museum without walls： Imagining new formative spaces

The ＂Museum of Childhood＂ is a project connected to the Post-Graduate Program in Education at Unesc （Brazil） and since 2005 has been developing interfaces with research, teaching and extension. In this paper, the authors would like to show how the museological conception of the Museum of Childhood makes imagination from one of the central axis of its formative relation with the public. Such conception breaks with the traditional view of museums as buildings where old things are collected and preserved. In fact, the Museum of Childhood, in the light of its objective conditions, wants to be a museum without walls, a museum that, using the device of spatial demarcation, spreads itself in the university campus and other public places, with the objective of communicating with the people. This conception comes closer to the transgressive nature of modem arts, which desacralizes the work of art as masterpiece and proposed, for example, the fugacity of installations and aesthetic interventions. This conception takes the Benjaminian notion of the past as the dimension where other futures remain latent, that is, the museum is seen not as a guardian of the past, but as an establishment that wants to use its collections to communicate with the public. The overrunning of the static physical space, for example, forces the public to recreate its horizon of expectations concerning what a museum show be. In order to accomplish its original objectives, the Museum of Childhood works intensively on the formation of the public by proposing monitored visits in which creative activities are developed and by improving its homepage.     

Quantitative analysis of Brazilian football players' organisation on the pitch

The purpose of this study was to characterise Brazilian teams' coverage area and spread on the pitch while attacking and defending and to analyse the teams' organisation in tackle and shot on goal situations. We obtained the trajectories of 223 players in eight games with a tracking method. Team area was defined as the area of the convex hull formed by players' positions. Team spread was defined as the Frobenius norm of the distance-between-player matrix. We calculated teams' area and spread over time and in situations of shots on goal (n = 233) and tackles (n = 1897). While the players attacked, spread and area (median +/- confidence interval) ranged from 322.9 +/- 0.8 to 387.8 +/- 1.0 m and from 905.4 +/- 4.4 to 1407.6 +/- 5.5 m2, respectively. On defence, the values were smaller (p < 0.05) and ranged from 283.4 +/- 0.9 to 325.8 +/- 0.9 m and from 773.8 +/- 4.6 to 1158.4 +/- 5.5 m2 for the spread and the area. In defending circumstances, the teams presented a greater area and spread when they suffered shots on goal than when the teams performed tackles. In attacking situations, the teams presented a greater area and spread when they suffered tackles than when they performed shots on goal. The results allowed showing the attacking-defending interaction between Brazilian teams.     

How education background affects design outcome: teaching product development to mechanical engineers,industrial designers and managers

ABSTRACT

Product design and development (PDD) is a current topic of academic and industrial research. Emphasis on innovation and entrepreneurship, as well as design thinking and creativity has been recently pulled together into the teaching and research on PDD. This paper looks into a multidisciplinary setting made up of three similar but independent PDD masters courses taught at three higher education institutions, having the same assessment, syllabus, assignments and outcomes. As expected, students’ projects foci are different. The outcomes of this experience were confronted with an ex-post literature review, which generated thorough guidelines that supported an innovative proposal for PDD education, to be implemented into an interdisciplinary Summer School. Significant generalisable contributions for educating modern engineers, designers and business entrepreneurs are expected, instead of just teaching methods of engineering, design and entrepreneurship at the case universities. The limitation of the used inductive reasoning concerns ‘truth’ being suggested but not assured.     

Voluntary and Involuntary Control of Attention in Adolescents Born Very Preterm: A Study of Eye Movements

Very preterm birth is associated with attention deficits that interfere with academic performance. A better understanding of attention processes is necessary to support very preterm born children. This study examined voluntary and involuntary attentional control in very preterm born adolescents by measuring saccadic eye movements. Additionally, these control processes were related to symptoms of inattention, intelligence, and academic performance. Participants included 47 very preterm and 61 full-term born 13-years-old adolescents. Oculomotor control was assessed using the antisaccade and oculomotor capture paradigm. Very preterm born adolescents showed deficits in antisaccade but not in oculomotor capture performance, indicating impairments in voluntary but not involuntary attentional control. These impairments mediated the relation between very preterm birth and inattention, intelligence, and academic performance.     

Nonlinear modeling and robust LMI fuzzy control of overhead crane systems

Overhead cranes are widely used structures for lifting and conveying heavy loads. The development of feedback control systems for such equipment is important due to the large number of potential applications and advantages over manual operation concerning stability and robustness. This paper aims to represent the key nonlinear dynamics of crane systems by means of a state-space fuzzy model with compact rule-base structure. The fuzzy model is useful to assist the design of a fuzzy controller based on the concept of parallel compensation. A well-posed conservative linear-matrix-inequality (LMI) feasibility problem is formulated so that a solution guarantees closed-loop Lyapunov stability, bounded control inputs, quick positioning of the supporting cart, and suppression of load oscillations and collisions. The fuzzy controller is composed by rules with linear control laws derived from local state-space models. The controller warrants asymptotic convergence of the states. Due to the nonlinear nature of the fuzzy model and controller, Jacobian linearization is avoided. The proposed fuzzy control approach for cranes has shown to be more effective and robust than an optimal quadratic controller, and able to move cargo smoothly and safely to a destination. Particularly, constrained and smoother control inputs avoid actuator saturation, and tend to increase its lifetime. Laboratory experiments using the LMI fuzzy controller and actual data validates the approach for cranes in actual scenario.
