An investigation into pricing anomalies and the influence of information processing constraints on forecasts derived from sports betting markets
No full textThis thesis is made up of three separate papers, all of which explore how decision makers discount information in simplified financial markets where participants’ behaviour can be easily segmented. Overall, this thesis provides a valuable contribution to the existing knowledge of pricing anomalies in betting markets by identifying uncharted research niches and adopting novel applications. The first paper explicitly examines how legacy information affects the accuracy of probability forecasts, utilising data from a low liquidity sports betting market where the demographic of bettors is predominantly homogeneous. The findings are important as they shed new light on the ability of participants to discount older information, especially as increasing amounts of past performance information are processed. The second paper explores the influence of order effects in horse race betting markets which are generally ranked from highest to the lowest quality of contenders. Researchsuggests the way information is presented can impact how effectively information is processed by individuals. This paper finds evidence of order effects in relation to more favoured contenders which has serious implications for the most widely researched phenomena in betting markets, that is, the favourite-longshot bias. The third paper takes a novel twist on a commonly employed benchmark model to focus purely on market makers’ ability to frame accurate opening price odds. Paper three directly tests whether public information plays a role in price movements over the duration of betting. In particular, the findings challenge the current consensus in the literature
Towards a new employment relationship model
No full textPurpose – The purpose of this study is to examine and extend Noer’s theoretical model of the new\ud
employment relationship.\ud
Design/methodology/approach – Case study methodology is used to scrutinise the model. The\ud
results of a literature-based survey on the elements underpinning the five values in the model are\ud
analysed from dual perspectives of individual and organization using a multi-source assessment\ud
instrument. A schema is developed to guide and inform a series of focus group discussions from an\ud
analysis of the survey data. Using content analysis, the transcripts from the focus group discussions\ud
are evaluated using the model’s values and their elements. The transcripts are also reviewed for\ud
implicit themes. The case studied is Flight Centre Limited, an Australian-based international retail\ud
travel company.\ud
Findings – Using this approach, some elements of the five values in Noer’s model are identified as\ud
characteristic of the company’s psychological contract. Specifically, to some extent, the model’s values\ud
of flexible deployment, customer focus, performance focus, project-based work, and human spirit and\ud
work can be applied in this case. A further analysis of the transcripts validates three additional values\ud
in the psychological contract literature: commitment; learning and development; and open information.\ud
As a result of the findings, Noer’s model is extended to eight values.\ud
Research limitations/implications – The study offers a research-based model of the new\ud
employment relationship. Since generalisations from the case study findings cannot be applied directly\ud
to other settings, the opportunity to test this model in a variety of contexts is open to other researchers.\ud
Originality/value – In practice, the methodology used is a unique process for benchmarking the\ud
psychological contract. The process may be applied in other business settings. By doing so,\ud
organization development professionals have a consulting framework for comparing an organization’s\ud
dominant psychological contract with the extended model presented here
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
