Statistical methods for analysing discrete and categorical data recorded in performance analysis     

Nevill AM  Atkinson G  Hughes MD  Cooper SM 《Journal of sports sciences》2002,20(10):829-844

In this paper, we identify appropriate statistical methods for analysing categorical differences in discrete variables or 'performance indicators' resulting from performance analysis. The random mechanisms associated with discrete events do not follow a normal distribution; that is, the normal distribution is a continuous not a discrete probability distribution. We propose appropriate statistical methods based on two key discrete probability distributions, the Poisson and binomial distributions. Two approaches are proposed and compared using examples from notational analysis. The first approach is based on the classic chi-square test of significance (both the goodness-of-fit test and the test of independence). The second approach adopts a more contemporary method based on log-linear and logit models fitted using the statistical software GLIM. Provided relatively simple one-way and two-way comparisons in categorical data are required, both of these approaches result in very similar conclusions. However, as soon as more complex models or higher-order comparisons are required, the approach based on log-linear and logit models is shown to be more effective. Indeed, when investigating those factors and categorical differences associated with binomial or binary response variables, such as the proportion of winners when attempting decisive shots in squash or the proportion of goals scored from all shots in association football, logit models become the only realistic method available. By applying log-linear and logit models to discrete events resulting from notational analysis, greater insight into the underlying mechanisms associated with sport performance can be achieved.  相似文献   

Academic medical libraries' policies and procedures for notifying library users of retracted scientific publications   总被引：1，自引：0，他引：1  

Hughes C 《Medical reference services quarterly》1998,17(2):37-42

Academic medical libraries have a responsibility to inform library users regarding retracted publications. Many have created policies and procedures that identify flawed journal articles. A questionnaire was sent to the 129 academic medical libraries in the United States and Canada to find out how many had policies and procedures for identifying retracted publications. Of the returned questionnaires, 59% had no policy and no practice for calling the attention of the library user to retracted publications. Forty-one percent of the libraries called attention to retractions with or without a formal policy for doing so. Several responding libraries included their policy statement with the survey. The increasing number of academic medical libraries that realize the importance of having policies and practices in place highlights the necessity for this procedure.  相似文献

Examples of Good Practice when Dealing with Bullying in a Further/Higher Education College     

Gavin Hughes 《Pastoral Care in Education》2001,19(3):10-13

This qualitative study, conducted via interviews, focuses on the strategies used by tutors and support staff in dealing with bullying in an FE/HE college. This area is under researched and yet studies have shown that 10 per cent of students in FE experience bullying (McDougall, 1999). It was found that bullying was being dealt with effectively using a range of approaches. The examples of good practice found in this study correspond with the more extensive work into primary and secondary schools by Byrne (1994), Tattum and Herbert (1993) and Sharp and Smith (1993). All respondents treated the issue seriously and relationships built up between tutors/support staff and the students were the crucial factor.  相似文献   

Balancing Cultural Diversity and Social Cohesion in Education: The Potential of Shared Education in Divided Contexts     

Rebecca Loader  Joanne Hughes 《British Journal of Educational Studies》2017,65(1):3-25

This article considers how the education systems of divided societies have been shaped in response to the experience of ethnic and religious conflict. The analysis identifies two competing priorities in such contexts – the development of social cohesion and the protection of cultural, ethnic and religious identities – and explores how these may be reconciled through a model of ‘shared education’. Drawing on research evidence and recent experience of shared education in Northern Ireland, the Former Yugoslav Republic of Macedonia and Cyprus, we reflect on the advantages and challenges of this model in areas experiencing conflict and division.  相似文献   

Longitudinal Effects of Teacher and Student Perceptions of Teacher-Student Relationship Qualities on Academic Adjustment     

Hughes JN 《The Elementary school journal》2011,112(1):38-60

The shared and unique effects of teacher and student reports of teacher student relationship quality (TSRQ) in second and third grade on academic self views, behavioral engagement, and achievement the following year were investigated in a sample of 714 academically at-risk students. Teacher and student reports of teacher-student support and conflict showed low correspondence. As a block, teacher and student reports of TSRQ predicted all outcomes, above prior performance on that outcome and background variables. Student reports uniquely predicted school belonging, perceived academic competence, and math achievement. Teacher reports uniquely predicted behavioral engagement and child perceived academic competence. Teacher and student reports of the teacher-student relationship assess largely different constructs that predict different outcomes. Implications of findings for practice and research are discussed.  相似文献

On the Nonsmooth,Nonconstant Velocity of Braille Reading and Reversals     

Barry Hughes  Amber McClelland  Dion Henare 《Scientific Studies of Reading》2014,18(2):94-113

Relative to print reading, braille-reading finger movements are held to be of more constant speed, with continuous and exhaustive contact with all words. However, the continuity of movements is intermittent in two distinct ways: (a) readers reverse direction and reread material already encountered and (b) the continual fluctuations of velocity between phases of acceleration and deceleration. We analyze recordings of experienced readers’ encounters with ambiguous sentences predicted to encourage more reversals, and we undertake comparative kinematic analyses of the finger movements during such reading. The data suggest that when reversals are initiated and where they are targeted reflect language-processing demands. However, their kinematic properties are not qualitatively different from those of forward reading. We conclude that how readers of braille move the reading finger—both forward and in reverse—is primarily influenced by the control properties of low-velocity movements and only secondarily by language properties.  相似文献
