How To Scale Coded Text Units Without Bias: A Response To Gemenis, Kenneth Benoit, Michael Laver, Will Lowe, Slava Mikhaylov Sep 2012

How To Scale Coded Text Units Without Bias: A Response To Gemenis, Kenneth Benoit, Michael Laver, Will Lowe, Slava Mikhaylov

Research Collection School of Social Sciences

Coding non-manifesto documents as if they were genuine policy platforms produced at election time clearly raises serious issues with error when these codings are used in the standard manner to estimate left-right policy positions. In addition to the long term solution of improving the document base of the Manifesto Project identified by Gemenis (2012), we argue that immediate gains in manifesto-based estimates of policy positions can be realised by using the confrontational logit scales from Lowe et al. (2011), which addresses the problems of scale content and scale construction that are exacerbated by but not unique to the problems found …

Public And Private Worlds? Social History, Gender And Space, Fiona Williamson Sep 2012

Public And Private Worlds? Social History, Gender And Space, Fiona Williamson

Research Collection School of Social Sciences

Michael McKeon’s The Secret History of Domesticity is an important contribution to cultural and literary history, exploring how concepts of public and private evolved. His quest to uncover the ‘division of knowledge’ takes the reader on a journey through the low and high culture of literary genre, the history of print, art, architecture, entertainment, politics and social theory. This essay compares McKeon’s reading of public and private in light of the recent ‘spatial turn’ in social and gender history. The ‘spatial turn’ offers a close lens into the lived experience of past peoples in the same way that McKeon claims …

Constraining The Temperature History Of The Past Millennium Using Early Instrumental Observations, P Brohan, Rob Allan, J. Eric Freeman, D. Wheeler, Clive Wilkinson, Fiona Williamson Sep 2012

Constraining The Temperature History Of The Past Millennium Using Early Instrumental Observations, P Brohan, Rob Allan, J. Eric Freeman, D. Wheeler, Clive Wilkinson, Fiona Williamson

Research Collection School of Social Sciences

The current assessment that twentieth-century global temperature change is unusual in the context of the last thousand years relies on estimates of temperature changes from natural proxies (tree-rings, ice-cores, etc.) and climate model simulations. Confidence in such estimates is limited by difficulties in calibrating the proxies and systematic differences between proxy reconstructions and model simulations. As the difference between the estimates extends into the relatively recent period of the early nineteenth century it is possible to compare them with a reliable instrumental estimate of the temperature change over that period, provided that enough early thermometer observations, covering a wide enough …

Marijuana Use Development Over The Course Of Adolescence Among North American Indigenous Youth, Jacob E. Cheadle, Kelley J. Sittner Hartshorn

Department of Sociology: Faculty Publications

This study investigated the links between marijuana use trajectories and marijuana abuse/ dependence (DSM-IV) using five waves of data from 718 North American Indigenous adolescents between 10 and 17 years from eight reservations sharing a common language and culture. Growth mixture models indicated that 15% of youth began using by 11–12 years of age and that another 20% began shortly thereafter. These early users had odds of abuse/dependence 6.5 times larger than abstainers. Girls were also unexpectedly found to be particularly at risk of early use, and this did not reflect other background and psychosocial factors, including friend use. While …

The Engagement Of Highly Skilled Egyptian Migrants In Oecd Countries, Iman Dawood Sep 2012

The Engagement Of Highly Skilled Egyptian Migrants In Oecd Countries, Iman Dawood

Faculty Journal Articles

Within the Middle East and North Africa region, Egypt can certainly be considered the number one emigration country in terms of total number of emigrants1 . But even within a larger pool of countries, the developing countries for instance, Egypt still occupies a position within the list of top ten-emigration countries according to the World Bank2 . Egypt is also amongst the top remittance-receiving countries with only thirteen other countries worldwide receiving a higher level of remittances in the year 20103 . While accounts of the actual number of Egyptian migrants vary greatly due to the unavailability of accurate and …

The Effects Of Coaching On Situational Judgment Tests In High-Stakes Selection, Filip Lievens, Tine Buyse, Paul R. Sackett, Brian S. Connelly Sep 2012

The Effects Of Coaching On Situational Judgment Tests In High-Stakes Selection, Filip Lievens, Tine Buyse, Paul R. Sackett, Brian S. Connelly

Research Collection Lee Kong Chian School Of Business

Although the evidence for the use of situational judgment tests (SJTs) in high-stakes testing has been generally promising, questions have been raised regarding the potential coachability of SJTs. This study reports the first examination of the effects of coaching on SJT scores in an operational high-stakes setting. We contrast findings from a simple comparison of SJT scores for coached and uncoached participants (posttest only) with three different approaches to deal with the effects of self-selection into coaching programs, namely using a pretest as a covariate and using two different forms of propensity score-based matching using a wide range of variables …

Responding To Personality Tests In A Selection Context: The Role Of The Ability To Identify Criteria And The Ideal-Employee Factor, Ute-Christine Kelhe, Martin Kleinmann, Thomas Hartstein, Klaus G. Melchers, Cornelius J. Konig, Peter A. Heslin, Filip Lievens Sep 2012

Responding To Personality Tests In A Selection Context: The Role Of The Ability To Identify Criteria And The Ideal-Employee Factor, Ute-Christine Kelhe, Martin Kleinmann, Thomas Hartstein, Klaus G. Melchers, Cornelius J. Konig, Peter A. Heslin, Filip Lievens

Research Collection Lee Kong Chian School Of Business

Personality assessments are often distorted during personnel selection, resulting in a common "ideal-employee factor" (IEF) underlying ratings of theoretically unrelated constructs. However, this seems not to affect the personality measures' criterion-related validity. The current study attempts to explain this set of findings by combining the literature on response distortion with the ones on cognitive schemata and on candidates' ability to identify criteria (ATIC). During a simulated selection process, 149 participants filled out Big Five personality measures and participated in several high- and low-fidelity work simulations to estimate their managerial performance. Structural equation modeling showed that the IEF presents an indicator …

Lost Sleep And Cyberloafing: Evidence From The Laboratory And A Daylight Saving Time Quasi-Experiment, David T. Wagner, Christopher M. Barnes, Vivien K. G. Lim, D. Lance Ferris Sep 2012

Lost Sleep And Cyberloafing: Evidence From The Laboratory And A Daylight Saving Time Quasi-Experiment, David T. Wagner, Christopher M. Barnes, Vivien K. G. Lim, D. Lance Ferris

Research Collection Lee Kong Chian School Of Business

The Internet is a powerful tool that has changed the way people work. However, the ubiquity of the Internet has led to a new workplace threat to productivity—cyberloafing. Building on the ego depletion model of self-regulation, we examine how lost and low-quality sleep influence employee cyberloafing behaviors and how individual differences in conscientiousness moderate these effects. We also demonstrate that the shift to Daylight Saving Time (DST) results in a dramatic increase in cyberloafing behavior at the national level. We first tested the DST–cyberloafing relation through a national quasi-experiment, then directly tested the relation between sleep and cyberloafing in a …

Real Time Ddos Detection Using Fuzzy Estimators, Sn Shiaeles, V Katos, As Karakos, Bk Papadopoulos Sep 2012

Real Time Ddos Detection Using Fuzzy Estimators, Sn Shiaeles, V Katos, As Karakos, Bk Papadopoulos

School of Engineering, Computing and Mathematics

We propose a method for DDoS detection by constructing a fuzzy estimator on the mean packet inter arrival times. We divided the problem into two challenges, the first being the actual detection of the DDoS event taking place and the second being the identification of the offending IP addresses. We have imposed strict real time constraints for the first challenge and more relaxed constraints for the identification of addresses. Through empirical evaluation we confirmed that the detection can be completed within improved real time limits and that by using fuzzy estimators instead of crisp statistical descriptors we can avoid the …

Comparing Transient Simulation With Thermography Time Series, M Fox, D Coley, Wilde P De, Smr Goodhew Sep 2012

Comparing Transient Simulation With Thermography Time Series, M Fox, D Coley, Wilde P De, Smr Goodhew

School of Art, Design and Architecture

Thermography is an emerging technology used by construction professionals focused upon the thermal and condition performance of buildings. However, the interpretation of thermal images is difficult and often misinterpreted. This paper reports on initial work that compares thermographic images from relatively simple experimental setups with transient models of the same experiment. Thermographic images were obtained from a FLIR ThermaCam S65 while simulation was undertaken using the Voltra transient heat transfer program. The work highlights some of the inherent problems with interpreting thermal images of actual buildings, and suggests how these comparisons can provid a better understanding of real-life material performance.

Canine Urinary Incontinence Post-Neutering: A Review Of Associated Factors, Pathophysiology And Treatment Options, Suppawiwat Ponglowhapan, Muhammad Khalid, David Church

The Thai Journal of Veterinary Medicine

Canine urinary incontinence is commonly encountered in small animal veterinary practice with highprevalence in spayed female dogs. The diagnosis of neutering-induced urinary incontinence is usually based onclinical signs, history and elimination of other possible diagnoses. The proposed predispositions to incontinence thatfollows neutering including gender, breed, body weight, obesity, tail docking, spaying technique (ovariectomy andovariohysterectomy) and morphology of the LUT, e.g. the position of neck of the bladder and urethral length, have allbeen investigated. At present, the exact underlying mechanisms are not fully understood. However, it is widelyagreed that the condition is multi-factorial and hormone-associated. The role of gonadotrophin LH and …
