Continuous frequency and phase spectrograms： a study of their 2D and 3D capabilities and application to musical signal analysis     

Laurent Navarro  Guy Courbebaisse  Jean-Charles Pinoli 《浙江大学学报(A卷英文版)》2008,9(2):199-206

A new lighting and enlargement on phase spectrogram （PS） and frequency spectrogram （FS） is presented in this paper. These representations result from the coupling of power spectrogram and short time Fourier transform （STFT）. The main contribution is the construction of the 3D phase spectrogram （3DPS） and the 3D frequency spectrogram （3DFS）. These new tools allow such specific test signals as small slope linear chirp, phase jump case of musical signal analysis is reported. The main objective is to and small frequency jump to be analyzed. An application detect small frequency and phase variations in order to characterize each type of sound attack without losing the amplitude information given by power spectrogram  相似文献   

A mathematical formulation of keyword compression for thesauri     

Louis-Gavet Guy 《Information processing & management》1977,13(3):189-200

In this paper we demonstrate a new method for concentrating the set of key-words of a thesaurus. This method is based on a mathematical study that we have carried out into the distribution of characters in a defined natural language.We have built a function f of concentration which generates only a few synonyms. In applying this function to the set of key-words of a thesaurus, we reduce each key-word to four characters without synonymity. (For three characters we have a rate of synonymity of approx. 1/1000th.)A new structure of binary files allows the thesaurus to be contained in a table of less than 700 bytes.  相似文献

The hierarchical effects of perceived quality on perceived value,satisfaction, and loyalty: Empirical results from public,outdoor aquatic centres in Australia     

Gary Howat  Guy Assaker 《Sport Management Review》2013,16(3):268-284

Drawing on the literature on service quality, value, satisfaction, and loyalty, the present study assumes a hierarchical, multidimensional scheme for perceived quality focussing on four process dimensions of service quality. The aim of this study is to test a comprehensive model of perceived quality on loyalty in the context of public aquatic centres in Australia. Using partial least squares structural equation modelling (PLS-SEM) on a sample of 961 repeat customers of three outdoor public aquatic centres, results from this study reveal that four first-order process quality dimensions—facility presentation, core services, secondary services and staff—are significant in determining their higher-order perceived quality construct, with facility presentation and staff having the strongest influence. Moreover, the results of the present study indicate that overall satisfaction fully mediates the impact of perceived quality and perceived value on loyalty (behavioural intentions), with perceived quality having the strongest influence on overall satisfaction and loyalty. The present study provides an enhanced conceptualisation of the perceived quality construct in the context of public aquatic centres and contributes to the debate on the relationships among service quality, satisfaction, value, and loyalty in the sport and leisure context. In addition to strengthening theoretical understandings, the present study offers a service quality model that allows aquatic centre managers to identify specific attributes of the service that can be managed to influence loyalty more favourably.  相似文献   

The (im)materiality of literacy: the significance of subjectivity to new literacies research     

Cathy Burnett  Guy Merchant  Kate Pahl  Jennifer Rowsell 《Discourse: Studies in the Cultural Politics of Education》2014,35(1):90-103

This article deconstructs the online and offline experience to show its complexities and idiosyncratic nature. It proposes a theoretical framework designed to conceptualise aspects of meaning-making across on- and offline contexts. In arguing for the ‘(im)materiality’ of literacy, it makes four propositions which highlight the complex and diverse relationships between the immaterial and material associated with meaning-making. Complementing existing sociocultural perspectives on literacy, the article draws attention to the significance of relationships between space, mediation, materiality and embodiment to literacy practices. This in turn emphasises the importance of the subjective in understanding how different locations, experiences and so forth inflect literacy practice. The article concludes by drawing on the Deleuzian concept of the ‘baroque’ to suggest that this focus on articulations between the material and immaterial helps us to see literacy as multiply and flexibly situated.  相似文献   

The (mis)interpretation of teaching evaluations by college faculty and administrators     

Guy A. Boysen  Timothy J. Kelly  Holly N. Raesly  Robert W. Casner 《Assessment & Evaluation in Higher Education》2014,39(6):641-656

Student evaluations of teaching are ubiquitous and impactful on the careers of college teachers. However, there is limited empirical research documenting the accuracy of people’s efforts in interpreting teaching evaluations. The current research consisted of three studies documenting the effect of small mean differences in teaching evaluations on judgements about teachers. Differences in means small enough to be within the margin of error significantly impacted faculty members’ assignment of merit-based rewards (Study 1), department heads’ evaluation of teaching techniques (Study 2) and faculty members’ evaluation of specific teaching skills (Study 3). The results suggest that faculty and administrators do not apply appropriate statistical principles when evaluating teaching evaluations and instead use a general heuristic that higher evaluations are better.  相似文献   

Do null phonemic masking effects reflect strategic control of phonology?     

Berent  Iris  Van Orden  Guy 《Reading and writing》2003,16(4):349-376

Verstaen, Humphreys, Olson and D'Ydewalle [(1995) Journal of Memory and Language, 34, 335–356] reported null phonemic masking effectswith homophone targets under conditionsdiscouraging reliance on phonology. Theyattributed these null effects to the absence ofreliance on phonology, concluding that relianceon phonology may be strategically controlled. Two studies using Verstaen et al.'s methodoccasionally replicate these null phonemicmasking effects, but challenge theirinterpretation. The emergence of null phonemicmasking effects was unrelated to the strategymanipulation. Conversely, evidence forphonology emerged in homophone errorsregardless of the strategy manipulation anddespite null phonemic masking effects. Ourfindings reflect an inherent instability in theperception of homophones. We demonstrate thatthis instability is directly due to reliance onphonology, rather than to its control.  相似文献   

What Kind of Learning Does Self‐assessment Drive? Developing a ‘nose’ for quality: comments on Klenowski (1995)     

Guy Claxton 《Assessment in Education: Principles, Policy & Practice》1995,2(3):339-343

Klenowski (1995) identifies three aspects of ‘self‐assessment’. The present commentary examines these from the point of view of the development of learning‐to‐learn or ‘learning acumen’, which, it is proposed, comprises resilience, resourcefulness, reflectivity and responsibility. The minimal sense of self‐evaluation, in which students merely learn to monitor their performance in terms of externally specified criteria, may raise attainment without improving learning acumen, and may even damage it. What constitutes ‘good work’ is, in many domains, not reducible to the application of predetermined criteria. Self‐evaluation is essentially an intuitive process. Learning to see self‐evaluation as ‘marking one's own work’ by applying a checklist of criteria prevents the development of this intuitive ability.  相似文献

Anything goes: Or,how the accommodation of Europe's universities to European integration integrates an inspiring number of contradictions     

Guy Neave 《Tertiary Education and Management》2013,19(3):181-197

Abstract

This article analyses the implications for the integration of higher education in Europe as presented by the Bologna process. It examines the evidence presented in official documents which claim a wide‐spread consensus for this initiative. The article analyses the particular ideological commitment built into the Bologna process in the light of its four objectives Mobility, Employ ability, Competitiveness and Attractiveness. It questions whether that consensus, largely taken for granted at the higher levels of political discussion, is fully reflected in ‘le pays reel’ ‐ at the chalk face. It argues that the main test of the Bologna ‘principles’ will come when talk gives way to implementation, both at the level of first degrees and in the area of research training.  相似文献
