The wider context of performance analysis and it application in the football coaching process

The evolving role of PA and the associated proliferation of positions and internships within high performance sport has driven consideration for a change, or at least a broadening, of emphasis for use of PA analysis. In order to explore the evolution of PA from both an academic and practitioner perspective this paper considers the wider conceptual use of PA analysis. In establishing this, the paper has 4 key aims: (1) To establish working definitions of PA and where it sits within the contemporary sports science and coaching process continuum; (2) To consider how PA is currently used in relation to data generation; (3) To explore how PA could be used to ensure transfer of information, and; (4) To give consideration to the practical constrains potentially faced by coach and analyst when implementing PA strategies in the future

Correlates of statewise participation in the great Indian growth turnaround: some preliminary robustness results

This short note provides some supplementary analysis to the regressions in Section 5 of Ghate and Wright (forthcoming), that was carried out after the refereeing process for that paper was completed, and hence could not be included in the published version. It is not a free-standing paper, but is intended to be read in conjunction with the published paper

Finding the far right online: an exploratory study of white supremacist websites

White supremacists and the Far Right political movement in the UK have, had considerable success in spreading their messages through Web sites. Some of these Web sites clearly contribute to an enabling environment for racially motivated violence in our towns and cities and possibly help to underpin also the rise of, and support for, the Far Right in the UK and elsewhere in Europe. From a position that acknowledges the enduring issue of white hegemony in Western societies, this paper provides a number of research-based recommendations for further research and future policy and practice in tackling white supremacist racial hatred on the Net

Blade selection for a modern axial-flow compressor

The procedures leading to successful design of an axial flow compressor are discussed. The three related approaches to cascade selection are: (1) experimental approach which relies on the use of experimental results from identical cascades to satisfy the velocity diagrams calculated, (2) a purely analytical procedure whereby blade shapes are calculated from the theoretical cascade and viscous flow equations, and (3) a semiempirical procedure which used experimental data together with the theoretically derived functional relations to relate the cascade parameters. Diagrams of typical transonic blade sections with uncambered leading edges are presented

COMMENTARY Enhancing consumer empowerment

Purpose of this paper: Much of the literature on consumer empowerment focuses on consumers’ efforts to regain control of their consumption processes from suppliers. Our purpose is to argue that many suppliers achieve success by trying hard to empower consumers. The mechanism by which this takes place consists of researching and providing what consumers want. Consumers feel empowered when they are able to enjoy the consumption process. This is of particular note in shopping, which is not simply obtaining products but also experience and enjoyment. Design/methodology/approach: Research is examined into the links between firms’ efforts to understand what consumers want, atmospheric stimuli, emotions and buying behaviour. Findings: We find that successful firms’ try hard to understand what consumers want and to improve consumer satisfaction and empowerment by providing pleasant marketing environments and apt, relevant information. Research limitations/implications: The approach is based on prior literature. We examine marketing to consumers in company locations, e.g. stores, malls, restaurants and banks to examine specific evidence of the effects of atmospheric stimuli such as aroma, music and video screen media. Practical implications: We contend that firms can and do become successful in a competitive arena by providing pleasant environments and information that people want. What is original/value of paper?: We show how consumer empowerment is an important concept. This paper contributes since there is a dearth of writings specifically about consumer empowerment in the marketing literature. Far from the popular view of consumers being manipulated by firms, successful firms try hard to and succeed in empowering consumers in their marketing activities

Applying scenarios in user-centred design to develop a sketching interface for human modelling and animation

This paper presents our user and usability studies for applying scenarios in user-centred design to develop a sketching interface for virtual human modelling and animation. In this approach, we utilise the User Centred System Design (UCSD) strategy and spiral lifecycles to ensure system usability and functionalities. A series of usability techniques were employed. After the initial conceptual design, a preliminary user study (including questionnaires and sketching observations) was undertaken to establish the formal interface design. Second, an informal user test was conducted on the first prototype: a “sketch-based 3D stick figure animation interface”. Finally, a formal user evaluation (including performance tests, sketching observations, and interviews) was carried out on the latest version: a “sketch-based virtual human builder”. During this iterative process, various paper-based and electronic-based sketching scenarios were created, which were acted-out by users to help designers evoke and verify design ideas, identify users’ needs, and test the prototype interfaces in real contexts. Benefiting from applying the UCSD strategy and scenario-based design to develop a natural and supportive sketching interface, our investigation can be a useful instantiation for the design of other sketching interfaces where these techniques have not been widely acknowledged and utilised in the past

Progress report 3 of cooperative program for design, fabrication, and testing of high modulus composite helicopter shafting

This report describes the third phase of work, the objective of which was to overcome the excessive brittleness of the previously developed UH-1 helicopter tail rotor drive shaft design which demonstrated a shaft train weight savings of 53.1% over the current 2024-T3 aluminum shaft train. A materials impact program demonstrated exceptionally noteworthy performance of two woven constructions containing E-glass and PRD 49-III (designation later changed to KEVLAR 49) fibers in an epoxy resin matrix. Thermoplastic matrices and PRD 49-III fiber provided impact resistance at low weight which was superior to composites having the same fiber in a thermoset resin matrix. A design, fabrication, and test program showed that shaft impact resistance could be improved over the previously developed graphite composite design at a cost in shaft train rate savings. The shaft train weight savings of the most impact tolerant construction was 4.0% over the current aluminum shaft train. Alternating plies of graphite and glass appear to provide substantially greater tube impact durability than that provided by hybridization of the two fibers into one tape wound to a ply design equivalent in strength and stiffness to that of the alternating ply design. Recommendations were made to continue research work to exploit the potential for more impact-durable structures through the use of KEVLAR 49 fiber, woven structures, thermoplastic matrices and THORNEL 50-S/KEVLAR 49 blends with thermoset matrices

A sketch-based gesture interface for rough 3D stick figure animation

This paper introduces a novel gesture interface for sketching out rough 3D stick figure animation. This interface can allow users to draw stick figures with the system automatic assistance in figure proportion control. Given a 2D hand-drawn stick figure under a parallel view, there is a challenge to reconstruct a unique 3D pose from a set of candidates. Our system utilizes figure perspective rendering, and introduces the concept of ‘thickness contrast’ as a sketch gesture combined with some other constraints/assumptions for pose recovery. The resulting pose can be further corrected, based on physical constraints of human body. Once obtaining a series of 3D stick figure poses, user can easily sketch out motion paths and timing, and add their preferable sound/background. The resulting 3D animation can be automatically synthesized in VRML. This system has been tested on a variety of input devices: electric whiteboard, tablet PC, as well as a standard mouse

Searching a biomedical bibliographic database from the Ukraine: the Panteleimon database

The Panteleimon database is available via the Internet and is a public access, database, capable of being searched in English, Russian and Ukrainian, covering medical, pharmaceutical, and chemical publications, published in he Ukraine and Russia from 1998. Describes the formulation of a search strategy for the Panteleimon database, for the identification of citations to randomized controlled trials (RCTs), and the comparison of the search results with records included in the Cochrane Library's Cochrane Central Register of Controlled Trials (CENTRAL) database, to evaluate how comprehensive the coverage of the CENTRAL database is for the literature of the Ukraine. The results indicated that Panteleimon is an easily accessible bibliographic database offering easy access to the Ukrainian biomedical literature. The English language retrieval functions picked up most of the reports of RCTs/CCTs (91 per cent precision but the lower recall of 55 per cent indicates the need to search using Russian and Ukrainian terms for completeness. The overall precision of 26 per cent compares favourably with a search for RCTs in EMBASE, carried out by the UK Cochrane Centre, where 70,000 reports of RCTs were identified from 300,000 records down-loaded (precision 23 per cent).
