OZCOTS 2008 Proceedings OZCOTS 2008 Proceedings of the 6th Australian Conference on Teaching Statistics Editors: Helen L. MacGillivray Queensland University of Technology Michael A. Martin Australian National University Statistical Education Section Victorian Branch ISBN: 978-0-9805950-0-0 1 PREFACE OZCOTS 2008 6th Australian Conference on Teaching Statistics The Australian Learning and Teaching Council, ALTC, http://www.altc.edu.au (formerly The Carrick Institute of Learning and Teaching in Higher Education), was established late 2004 and is an initiative of the Australian Government Department of Education, Science and Training. Its mission is to promote and advance learning and teaching in Australian higher education. OZCOTS 2008 combined the interests of the Statistics Education Section of the Statistical Society of Australia Inc with activities of Professor Helen MacGillivray’s ALTC Senior Fellowship program entitled “The teaching and assessment of statistical thinking within and across disciplines”. The Senior Fellowship Scheme supports leading educators to undertake strategic, high profile fellowship activities in areas that support the ALTC mission. Senior Fellows undertake a full time program of highly strategic fellowship activities over one year. Helen was one of the inaugural Senior Fellows. The six invited speakers at OZCOTS 2008 were members of the Fellowship’s international collaborative team, and their participation in OZCOTS 2008 was fully funded by the Fellowship. OZCOTS 2008 acknowledges the support of the Australian Statistical conference 2008 and the Victorian Branch of the Statistical Society of Australia Inc (SSAI) OZCOTS 2008 Conference Committee Helen MacGillivray (joint chair, joint editor), Queensland University of Technology Brian Phillips (joint chair, local arrangements), Swinburne University Michael Martin (joint editor), Australian National University Kay Lipson, Swinburne University Peter Howley, University of Newcastle 2 Brief Biographies of Invited Speakers Professor Adrian Bowman, Department of Statistics, University of Glasgow, Scotland. http://www.stats.gla.ac.uk/~adrian/ Adrian is an internationally respected statistician and researcher who has also been a leading innovator in statistics education for twenty years. He directs one of the principal nodes of the Higher Education Academy MSOR (Maths, Stats and OR) network. Many of the activities of the Glasgow node of this network provide information on, and resources for, the use of technology in the teaching and learning of statistics, but it also provides leadership in ideas and strategies in teaching statistics at the tertiary level. Previously Adrian was the leader of the STEPS project which was created by a consortium of eight UK university departments who developed problem-based learning materials in Statistics, delivered on the computer, which have been used around the world for the past decade. Adrian’s most recent interests in learning and teaching have been in developing the rpanel package. This provides a set of simple interactive controls for R functions which are particularly useful in creating dynamic graphics. The package is intended for general use but there is a particularly strong application in a teaching context. The web page for the project gives a variety of examples. Adrian’s research interests are nonparametric smoothing techniques, generalised additive models, three-dimensional shape modelling, graphics, statistical computing, and computer based learning. Dr Robert Gould, Director of the Centre for Teaching Statistics, University of California, Los Angeles. http://www.stat.ucla.edu/~rgould/ Rob is also vice-chair of undergraduate studies for the Department of Statistics at UCLA. His primary interests are in statistics education. He was co-principal investigator (with Roxy Peck), developer and instructor for the INSPIRE project - an on-line content-based course for beginning secondary school statistics teachers. He is a past chair of the American Statistical Association's Advisory Committee on Teacher Enhancement, and on the board of the ASA's Statistics Education Session. He is founding editor of Technology Instruction in Statistics Education, a new on-line journal that focuses on teaching with and about technology in statistics. He has worked as a consultant on the Tinkerplots (statistical graphics software for middle-school students) project with Cliff Konold and is currently the evaluator for Konold's Model Chance project, which is designing simulation software to teach probability to middle-school students. He is working with PI Joan Garfield as an evaluator for the NSF-funded AIMS project (Adapting and Implementing Innovative Material in Statistics). Professor Michael Martin, School of Finance and Applied Statistics, Australian National University. http://ecocomm.anu.edu.au/martin/ During his time as the Annenberg Distinguished Assistant Professor in Statistics at Stanford University, Michael was awarded the Dean’s Award for Distinguished Teaching in the School of Humanities and Sciences. In 1994 he returned to ANU where he convenes the degree program in actuarial studies. He received the ANU Vice- Chancellor’s Award for Excellence in Teaching in 2000, and an Australian Award for University Teaching in 2007. He is chair of the Statistical Education Section of the Statistical Society of Australia, and has been recently named as a Fellow of the American Statistical Association for his services to research and teaching in statistics. His research interests include resampling, statistical graphics, statistical education, biostatistics and environmental statistics. 3 Dr Peter Petocz, Associate Professor, Department of Statistics, Macquarie University. http://www.efs.mq.edu.au/staff/alphabetical_list_of_staff/peter_petocz Peter’s research interests include the biostatistical areas of nutrition and orthodontics, and a long-standing interest in mathematics and statistics pedagogy, both in practical terms and as a research field. On the pedagogical side, Peter is the author of a range of learning materials - textbooks, video packages and computer-based materials - and has been recognised for his teaching by a University of Technology, Sydney, Teaching Award in 2001, as a finalist at the AAUT National Teaching Awards in 2003, and a Citation for Outstanding Contributions to Student Learning in 2006. Peter has been undertaking joint research with Dr Anna Reid (Macquarie University) over a period of several years in pedagogical aspects of statistics and mathematics, and of graduate 'dispositions' such as sustainability, ethics and creativity. His long term strategy in this area is to investigate and publish in the broad area of professional preparation (particularly in the area of statistics and mathematics education) and to explore the connection between students' conceptions of their discipline and study in that discipline, their perceptions of their future profession, and the links between these ideas. Dr Larry Weldon, retired from Department of Statistics and Actuarial Science, Simon Fraser University, British Columbia, Canada. Larry has extensive teaching, and consulting experience in Administrative Studies, Medicine, Health Services, Bioscience, Engineering, and General contexts. He has long term teaching and administrative contracts in Indonesia, and advanced teaching specializations in data analysis, graphics, multivariate statistics. His research publications are in biostatistics, sampling, statistics education; he has also written two textbooks. Larry’s focus since 1983 has been to promote the updating of undergraduate statistics instruction to be more computer-intensive, include more graphics, more simulation, more resampling, more data analysis, and less rote inference. His web page www.stat.sfu.ca/~weldon documents this. Professor Chris Wild, Department of Statistics, University of Auckland. http://www.stat.auckland.ac.nz/~wild This department is the largest Statistics Department in Australia and New Zealand and is the birth place of . Currently, Chris’ main research interests are in developing methods for modelling response-selective data (e.g. case-control studies) and missing data problems, and in additive model extensions to multivariate regression techniques. A long term interest in the teaching of statistics has also developed into a research interest with particular emphasis on statistical thinking and reasoning processes. Chris is a Council member of the International Statistical Institute, a Fellow of the Royal Society of New Zealand, and was President of the International Association for Statistics Education (IASE) from 2003 to 2005. He is currently an Associate Editor of the International Statistical Review, and has been an Associate Editor of Biometrics , the Statistics Education Research Journal (SERJ), and the Australian and New Zealand Journal of Statistics. He was Head of Auckland's Department of Statistics 2003-2007 and co-led the University of Auckland's first-year statistics teaching team to a national Tertiary Teaching Excellence Award in 2003. 4 Paper Refereeing Process Papers referred to in the proceedings as refereed publication were reviewed by at least two referees selected from a panel of peers approved by the OZCOTS 2008 editors. The review process was "double blind" - identification of both authors and referees was removed from all documentation during the reviewing process. The Conference Committee took the view that the review of papers would give conference participants and other readers confidence

BROOKED ZoologyDepartment, Edward Grey Institute, South Parks Road, Oxford OX1 3PS, United Kingdom Abstract. Manx Shearwater(Pu@zuspujinus) pairs on Skokholm Island, Wales, typically breed together over several seasons,rearing one chick per year. There is a seasonal decline of chick fledgingweight. Even after correction for this decline, pairs tend to rear chicksthat are consistently heavier or lighter than predicted on the basis of the chick’s hatching date. These deviations may reflect pair quality. Weight and hatching date of a chick are not correlated with age of fledging. However, fledging agesof full siblingsshow significantlyless variation than thoseof nonsiblings.The characterappears highly heritable, with a heritability value around 0.84. This is the first study to addressthe extent to which the fledging age of wild birds is genetically determined. Key words: Manx Shearwater;Puffinus puffinus;fledging age; heritability.

  • The Selection-Mutation-Drift Theory of Synonymous Codon Usage
    Copyright 0 1991 by the Genetics Society of America The Selection-Mutation-DriftTheory of Synonymous Codon Usage Michael Bulmer' Department of Statistics, Oxford University, Oxford OX1 3TG, England Manuscript received March 13, 199 1 Accepted for publication July 6, 199 1 ABSTRACT It is argued that the bias in synonymous codon usage observed in unicellular organismsis due to a balance between the forces of selection and mutation in a finite population, with greaterbias in highly expressed genes reflecting stronger selection for efficiency of translation. A populationgenetic model is developed taking into account population size and selective differences between synonymous codons. A biochemical model is then developed to predict the magnitude of selective differences between synonymous codons in unicellular organisms in which growth rate (or possibly growth yield) can be equated with fitness. Selection can arise from differences in either the speed or the accuracy of translation. A model for the effect of speed of translation on fitness is considered in detail, a similar model for accuracy more briefly. The model is successful in predicting a difference in the degree of bias at thebeginning than inthe rest of the gene under some circumstances, as observed in Escherichia coli, but grossly overestimates the amount of bias expected. Possible reasons for this discrepancy are discussed. YNONYMOUScodons (coding forthe same balance ina finite population between selection favor- S amino acid) are often used with very different ing an optimal codon for each amino acid and muta- frequencies (GRANTHAMet al. 1980, 1981; IKEMURA tion together with drift allowing the persistence of 1985; BULMER1988a; SHARP1989; ANDERSONand nonoptimal codons.

  • The Development of Francis Galton's Ideas on the Mechanism of Heredity
    Journal of the History of Biology 32: 263–292, 1999. 263 © 1999 Kluwer Academic Publishers. Printed in the Netherlands. The Development of Francis Galton’s Ideas on the Mechanism of Heredity MICHAEL BULMER The Old Vicarage Chittlehampton Umberleigh EX37 9RQ U.K. Abstract. Galton greeted Darwin’s theory of pangenesis with enthusiasm, and tried to test the assumption that the hereditary particles circulate in the blood by transfusion experiments on rabbits. The failure of these experiments led him to reject this assumption, and in the 1870s he developed an alternative theory of heredity, which incorporated those parts of Darwin’s theory that did not involve the transportation of hereditary particles throughout the system. He supposed that the fertilized ovum contains a large number of hereditary elements, which he collectively called the “stirp,” a few of which are patent, developing into particular cell types, while the rest remain latent; the latent elements can be transmitted to the next generation, while the patent elements, with rare exceptions, cannot since they have developed into cells. The problem with this theory is that it does not explain the similarity between parent and child unless there is a high correlation between latent and patent elements. Galton probably came to realize this problem during his subsequent statistical work on heredity, and he quietly dropped the idea that patent elements are not transmitted in Natural Inheritance (1889). Galton thought that brothers and sisters had identical stirps, and he attributed differences between them to variability in the choice of patent elements from the stirp, that is to say to developmental variability.

  • 1 Introduction
    Notes 1 Introduction 1. Shils 1985: 166–7. 2. Huxley 1871: 152–3. Original emphasis. 3. Durkheim 1982: 162. 4. Mills 1959. 5. Durkheim 2005; Weber 1949. 6. Tönnies 2001. 7. Abbott 1999; Cristobal Young 2009. Demonstrating the extent to which they still command the attention of scholars in the early twenty-first cen- tury, a number of new studies of classical generation thinkers have been published in the past decade. For example, on Weber see Radkau 2009 and Ringer 2005, whilst on Durkheim see: Schmaus 2004 and Alexander and Smith 2005. 8. Weber 1958. On Weber’s difficult relationship with German sociology, in particular the German Sociological Association, see: Proctor 1991: part 2, especially chapter 10. 9. For example: Giddens 1971. Indeed, interpreting the relationship between Marx and Weber is a crucial part of understanding how thinkers from dif- ferent sides of the political spectrum, such as Talcott Parsons and Perry Anderson, who are discussed shortly, have given quite different readings of not just Weber but classical sociology as a whole. 10. For more on Parsons, see: Hamilton 1983; Holmwood 1996. 11. Parsons 1937. Parsons’ translations of Weber were, however, conservative compared to those of Weber’s European translators. As a consequence, the American reading of Weber, which presents him as providing an alternative to Marx’s historical materialism, is frequently very different to European interpretations of Weber. For more on the mid-twentieth-century political context for these different readings see: Roy MacLeod 2006. 12. Martin Bulmer 1985: 15; Shils 1980: 182, n. 7; MacRae 1972: 47. Indeed, Tawney provided a foreword to Parsons’ translation of Weber’s The Protestant Work Ethic and the Spirit of Capitalism.
