Discovering frequently recurring movement sequences in team-sport athlete spatiotemporal data

Athlete external load is typically analysed from predetermined movement thresholds. The combination of movement sequences and differences in these movements between playing positions is also currently unknown. This study developed a method to discover the frequently recurring movement sequences across playing position during matches. The external load of 12 international female netball athletes was collected by a local positioning system during four national-level matches. Velocity, acceleration and angular velocity were calculated from positional (X, Y) data, clustered via one-dimensional k-means and assigned a unique alphabetic label. Combinations of velocity, acceleration and angular velocity movement were compared using the Levenshtein distance and similarities computed by the longest common substring problem. The contribution of each movement sequence, according to playing position and relative to the wider data set, was then calculated via the Minkowski distance. A total of 10 frequently recurring combinations of movement were discovered, regardless of playing position. Only the wing attack, goal attack and goal defence playing positions are closely related. We developed a technique to discover the movement sequences, according to playing position, performed by elite netballers. This methodology can be extended to discover the frequently recurring movements within other team sports and across levels of competition.     

Head start children''s conceptions of and expectations for their future schooling

This study examined children's conceptions of and expectations for their future schooling, determined whether participation in a Transition Demonstration could affect these, and explored how these are related to children's academic achievement. Two cohorts, 151 former Head Start children completing kindergarten, and 171 children completing Head Start, were assessed. Two major themes in children's conceptions of school emerged: play and the cognitive or learning environment. Children realistically talked about the work of school becoming less play centered, more difficult, and more centered on academics as they moved from grade to grade. Children in the Demonstration group in both cohorts gave significantly more responses to the questions than those in the Comparison. Children's expectations for their future schooling were optimistic. There were several small but significant correlations between children's conceptions and expectations for school and their academic achievement as measured by subtests of the Wood-cock-Johnson-R.     

Culture as commons: theoretical challenges and empirical evidence from occupied cultural spaces in Italy

ABSTRACT

What happens when we try to understand art as a commons? Elinor Ostrom [(1990/2012). Governing the commons. Cambridge University Press] challenged Hardin’s “The tragedy of the commons” [(1968). Science, 162(3859), 1243–1248] demonstrating that the governance of common pool resources is not always destined to failure. Ostrom’s analysis was initially applied to the management of shared natural resources; however, over time the term “commons” has also been used to describe non-tangible resources, specifically knowledge. Can Ostrom’s theory of the commons inform artistic practice? This article investigates some challenges presented by these research questions and their implications for cultural policy. In order to provide an empirical ground for the discussion of this topic, this paper will analyse the case studies of two cultural spaces in Italy, Teatro Valle (Rome) and Asilo Filangieri (Naples), which were occupied by groups of cultural professionals and managed as commons between 2011 and 2016; the outcomes of these occupations indicate possible ways to develop a commons-oriented approach to culture.     

Inclusion of children with special needs in school-age child care programs

From an ecological perspective, the inclusion of children in school-age child care (SACC) requires collaboration among policy makers, educators, parents, and child care providers. Both typically and atypically developing children benefit from inclusive programs, yet they pose challenges for care-givers primarily due to lack of training, resources, and identification of successful inclusive program components. The process of successful SACC inclusion should be at the forefront of human service and research agendas.     

The engineer's role in the city

The European Society for Engineering Education is holding its eighth annual Conference in Paris this year. Our capital is greatly honoured to welcome for a few days the qualified representatives of a great number of European countries. This is the first SEFI meeting in France since your very first Conference in 1973. It is fortunate that this Conference is being held in Paris and that it has been possible to organize it with the close collaboration of the Engineering Schools (Grandes Ecoles) and the active help of the Study Committee for Engineering-training.
