Shared affordances guide interpersonal synergies in sport teams

This chapter focuses on the technologies for monitoring interpersonal coordination in team sports as this is an area that is receiving growing interest. They can be categorized into those based on: signal propagation sensing, inertial sensors, vision/image-based systems, and electro-magnetic tracking. The chapter provides an overview of the technologies available for studying interpersonal coordination, highlighting the key measurement principles. Vision systems can be categorized as marker based or non-marker based. This chapter talks about the capabilities and availability of technologies that can be used to assess interpersonal coordination are developing rapidly. Technologies such as mobile phones containing Global Positioning System (GPS) and inertial sensors offer considerable potential. These and other developing technologies offer the possibility of extending the scale and frequency of interpersonal coordination analyses in both research and real-world contexts. The chapter also explains the Global Navigation Satellite System (GNSS) that is a system of satellites provides positioning over the entire globe.info:eu-repo/semantics/acceptedVersio

What’s next in complex networks? Capturing the concept of attacking play in invasive team sports

The evolution of performance analysis within sports sciences is tied to technology development and practitioner demands. However, how individual and collective patterns self-organize and interact in invasive team sports remains elusive. Social network analysis has been recently proposed to resolve some aspects of this problem, and has proven successful in capturing collective features resulting from the interactions between team members as well as a powerful communication tool. Despite these advances, some fundamental team sports concepts such as an attacking play have not been properly captured by the more common applications of social network analysis to team sports performance. In this article, we propose a novel approach to team sports performance centered on sport concepts, namely that of an attacking play. Network theory and tools including temporal and bipartite or multilayered networks were used to capture this concept. We put forward eight questions directly related to team performance to discuss how common pitfalls in the use of network tools for capturing sports concepts can be avoided. Some answers are advanced in an attempt to be more precise in the description of team dynamics and to uncover other metrics directly applied to sport concepts, such as the structure and dynamics of attacking plays. Finally, we propose that, at this stage of knowledge, it may be advantageous to build up from fundamental sport concepts toward complex network theory and tools, and not the other way around.info:eu-repo/semantics/acceptedVersio

Interactions between soccer teams reveal both design and emergence: cooperation, competition and Zipf-Mandelbrot regularity

Considering soccer matches as complex systems facilitates the identification of properties that emerge from the interactions between players. Such properties include the regularities and statistical patterns that characterize couplings and sets between players established during matches. Empirical studies on the statistical distributions of number of items (e.g., words in texts) have shown that these distribu- tions follow scaling properties according to empirical laws known as Zipf-Mandelbrot. Here we investigate whether the (re)occurrence of pitch location of sets of players in a soccer match also obeys these empiri- cal laws. Data collected from 10 soccer matches shows that, for most sets of players, this seems to be the case. Exceptions were found in particular types of sets, such as goalkeeper and goal, and left defender and right attacker from opposite teams. Rather than challenging the hypothesis that a Zipf-Mandelbrot law defines this system, these exceptions may be explained by the players configuration design, which is a trait of human interaction within complex systems. This design expresses match strategy, before the team enters in such dynamical processes (the game).info:eu-repo/semantics/acceptedVersio

The role of Portuguese companies in the development of corporate strategies: case study

Strategy assumes a significant role in the managerial field concerning three levels of activity- corporate, business and functional. In academic terms, corporate strategy refers to a set of conceptualized strategies with distinct purposes. However, how does one make a decision regarding corporate strategies? Which forces, internal or external, are capable of influencing it? Are these strategies equally perceived? There is a gap of perception between the academic and business settings. Academically, corporate strategies are only explored towards their aim. However, under real conditions, companies are exposed to further features. Thus, the present investigation aims to develop an understanding about how distinct companies perceive strategy at the corporate level. This article relies on data from 30 companies, with a variety of industries. The results include valuable information regarding the main drivers of the decision behind corporate strategies and the dissimilarities associated to the perception of strategy at the corporate level.info:eu-repo/semantics/acceptedVersio

Lithium carbonate and coenzyme Q10 reduce cell death in a cell model of Machado-Joseph disease

Machado-Joseph disease (MJD) or spinocerebellar ataxia type 3 (SCA3) is an autosomal dominant neurodegenerative disorder caused by expansion of the polyglutamine domain of the ataxin-3 (ATX3) protein.

New type II Cepheids from VVV data towards the Galactic center

The Galactic center (GC) is the densest region of the Milky Way. Variability surveys towards the GC potentially provide the largest number of variable stars per square degree within the Galaxy. However, high stellar density is also a drawback due to blending. Moreover, the GC is affected by extreme reddening, therefore near infrared observations are needed. We plan to detect new variable stars towards the GC, focusing on type II Cepheids (T2Cs) which have the advantage of being brighter than RR Lyrae stars. We perform parallel Lomb-Scargle and Generalized Lomb-Scargle periodogram analysis of the $K_s$-band time series of the VISTA variables in the Via Lactea survey, to detect periodicities. We employ statistical parameters to clean our sample. We take account of periods, light amplitudes, distances, and proper motions to provide a classification of the candidate variables. We detected 1,019 periodic variable stars, of which 164 are T2Cs, 210 are Miras and 3 are classical Cepheids. We also found the first anomalous Cepheid in this region. We compare their photometric properties with overlapping catalogs and discuss their properties on the color-magnitude and Bailey diagrams. We present the most extensive catalog of T2Cs in the GC region to date. Offsets in E($J-K_s$) and in the reddening law cause very large ($\sim$1-2 kpc) uncertainties on distances in this region. We provide a catalog which will be the starting point for future spectroscopic surveys in the innermost regions of the Galaxy.Comment: A&A, accepte

Neuro-Behçet: MR study of a group of patients

Acta Med Port. 2006 Nov-Dec;19(6):494-8. Epub 2007 May 14. [Neuro-Behçet: MR study of a group of patients] [Article in Portuguese] Ramos C, Sá G, Tedim Cruz V, Lopes A, Xavier J, Cruz R. Serviço de Neurorradiologia, Hospital Geral de Santo António, Porto, Portugal. Abstract Behçet's disease is a chronic inflammatory, multisystemic disease of unknown aetiology. Central nervous system involvement occurs in a variable proportion of cases (4 to 49%) and is due to intracranial hypertension secondary to dural sinus thrombosis, inflammatory parenquimal lesions or recurrent meningoencephalitis. We reviewed 12 patients, 7 men and 5 women, aged between 27 to 40 years at the time of diagnosis. Neurological manifestations were secondary to parenquimal lesions in 7 patients, meningoencephalitis in 3 patients (including one with extensive medullary lesion) and dural sinus thrombosis in 2. Magnetic Resonance (MR) findings in Neuro-Behçet are non-specific. Nevertheless, MR has a role in characterizing brain lesions topography, helping in the diagnosis and in the follow-up of these patients. PMID: 17583610 [PubMed - indexed for MEDLINE]Free Articl
