The Benefits of Being Economics Professor A (and not Z)
Full text linkAlphabetic name ordering on multi-authored academic papers, which is the convention in the economics discipline and various other disciplines, is to the advantage of people whose last name initials are placed early in the alphabet. As it turns out, Professor A, who has been a first author more often than Professor Z, will have published more articles and experienced afaster growth rate over the course of her career as a result of reputation and visibility. Moreover, authors know that name ordering matters and indeed take ordering seriously: Several characteristics of an author group composition determine the decision to deviate from the default alphabetic name order to a significant extent.performance measurement, incentives, economists, name ordering
Hearing Faces and Seeing Voices: The Integration and Interaction of Face and Voice Processing
Full text linkCognitive understanding of voice recognition has borrowed much from the area of face processing, both in terms of the theoretical framework within which results are interpreted, and the methodology used to assess performance. A considerable body of research now exists to suggest that voice recognition may proceed in parallel with face recognition, and that the two pathways may combine to inform person recognition. However, rather than being independent or equivalent, these parallel pathways appear to interact to reveal interesting interference effects. The present paper reviews a series of studies that focus on a considerable and growing literature. The vulnerability of voice processing will be explored relative to face processing, and the interaction of these two pathways will be examined with reference to broader theoretical frameworks for person recognition

Networks of Causal Linkage Between Eigenmodes Characterize Behavioral Dynamics of Caenorhabditis elegans
Full text linkBehavioral phenotyping of model organisms has played an important role in unravelling the complexities of animal behavior. Techniques for classifying behavior often rely on easily identified changes in posture and motion. However, such approaches are likely to miss complex behaviors that cannot be readily distinguished by eye (e.g., behaviors produced by high dimensional dynamics). To explore this issue, we focus on the model organism Caenorhabditis elegans, where behaviors have been extensively recorded and classified. Using a dynamical systems lens, we identify high dimensional, nonlinear causal relationships between four basic shapes that describe worm motion (eigenmodes, also called "eigenworms"). We find relationships between all pairs of eigenmodes, but the timescales of the interactions vary between pairs and across individuals. Using these varying timescales, we create "interaction profiles" to represent an individual's behavioral dynamics. As desired, these profiles are able to distinguish well-known behavioral states: i.e., the profiles for foraging individuals are distinct from those of individuals exhibiting an escape response. More importantly, we find that interaction profiles can distinguish high dimensional behaviors among divergent mutant strains that were previously classified as phenotypically similar. Specifically, we find it is able to detect phenotypic behavioral differences not previously identified in strains related to dysfunction of hermaphrodite-specific neurons
‘Success in Britain comes with an awful lot of small print’: Greg Rusedski and the precarious performance of national identity
No full textSport continues to be one of the primary means through which notions of Englishness and Britishness are constructed, contested, and resisted. The legacy of the role of sport in the colonial project of the British Empire, combined with more recent connections between sport and far right fascist/nationalist politics, has made the association between Britishness, Englishness, and ethnic identity(ies) particularly intriguing. In this paper, these intersections are explored through British media coverage of the Canadian-born, British tennis player, Greg Rusedski. This coverage is examined through the lens of ‘performativity,’ as articulated by Judith Butler. Through a critical application of Butler's ideas, the ways in which the media seek to recognise and normalise certain identities, while problematising and excluding others, can be more fully appreciated. Thus, it was within newspaper framings of Rusedski that hegemonic notions of White Englishness could be performed, maintained, and embedded.Peer reviewedFinal article published.DC Author's Celebration 2022Britishness/EnglishnessGreg RusedskiJudith ButlerperformativityTim HenmanWhitenes

'Vive le defecteur!’ an analysis of the British media’s construction of Greg Rusedski’s national identity in the 1990s/2000s
No full textThis paper concerns the former professional tennis player from 1991 to 2007, Greg Rusedski, who was born in Canada but shifted national allegiance to Great Britain in 1995. Despite an impressive playing career, that saw him reach the US Open final in 1997 and attain a world-number-four ranking, alongside his steadfast efforts to ingratiate himself to the broader public, Rusedski’s British identity remained contested throughout his career. Focusing on four mainstream newspapers covering the political left and right, this paper analyses the British media’s treatment of Rusedski, and aims to develop an understanding of how his constructed identity as more or less ‘British’ fluctuated so markedly throughout his career. While his on-court results were certainly a factor in Rusedski’s swings between acceptance and rejection, this paper suggests a more nuanced analysis that takes into account, firstly, how Rusedski was positioned and characterised in relation to his countryman, the ‘quintessential Englishman’ Tim Henman, particularly in relation to his accent, ostensible personality, personal appearance and physique, and playing style, and, secondly, how Rusedski’s key period of success, in the latter half of 1997, can be contextualised in the light of broader socio-political events and developments.Peer reviewedPublished

Controlled potential coulometry digital prediction of endpoints
Full text linkIn 19589 J. J. Lingane published an article describing the behavior of an electrolysis using controlled potential coulometry. A typical titration was an hour or more, limiting the variety of applications of the technique. Stephens, Jakob, Rigdon and Harrar looked into the many procedures that have been proposed to locate the electrolysis endpoint without carrying it to completion. Unfortunately, the extrapolation techniques, when used off-line, shorten the electrolysis time only at the expense of operator time, and they generally sacrifice accuracy."
In their article, the Stephens research team propose a real time computer technique that determines the endpoint of the electrolysis while it is being carried out. In their technique, they utilize a total accumulated charge signal that is proportional to the amount of electroactive species that has been titrated. This signal is obtained by electronically integrating the cell current signal. By predicting the total charge signal at infinite time (Qoo). the original concentration of electroactive species can be determined. In the course of the mathematics involved in this prediction, the background current of the cell must be considered. The method the Stephens team used was to incorporate the background current into the error term used in the prediction. This method has its strong points and the results have as small as .02% relative error. It is the purpose of this paper to look into some alternate real time computer techniques of determining the initial concentration of the electroactive species using the cell current signal instead of total accumulated charge, and attempting to eliminate the background current from the data itself
