Are rating agencies' assignment opaque? Evidence from international banks by Bellotti, Tony, Matousek, Roman, Stewart, Chris

“…Although support vector machines can identify significant determinants we argue that ordered choice models are more reliable for this. Our findings suggest that ratings reflect a bank’s financial position, the timing of rating assignment and a bank’s country of origin. …”

Integration in European retail banking: evidence from savings and lending rates to the household sector by Rughoo, Aarti, Sarantis, Nicholas

“…This method analyses the degree as well as the speed of convergence, identifies the presence of club formation, and measures the behaviour of each country’s transition path relative to the panel average. We find evidence supporting integration in the deposit and short-term mortgage markets but not in the consumer credit market and longer term mortgages. …”

Managing transitions into UK Higher Education : experiences of international students from a pre-sessional English course by McKee, Susannah

“…This study seeks to examine individual accounts of a small number of international students at London Metropolitan University who had completed a pre-sessional Academic English course before their disciplinary studies. The aim was to find out how effectively they felt that the Pre-sessional course had prepared them for those studies, and to help inform the future development of the course, as well as gaining wider insight into the support needs of international students.…”

Playful UX for elephants by French, Fiona, Mancini, Clara, Sharp, Helen

“…Our contribution to the symposium will showcase the progress of the enrichment toys and explain in detail how we have collected feedback during participatory design sessions with our play-tester Valli, a female Asian elephant. We have attempted to gain information about her enthusiasm for interacting with different systems and also establish how effectively she can use different interfaces by measuring her responses during the sessions.…”

A novel circuit for investigating BJT current source dynamic resistance and capacitance at low DC bias current by Brinson, Mike, Faulkner, D. J.

“…This circuit is a single-stage differential amplifier driving series-connected diodes, and has the unusual property that its differential gain is equal to the number of load diodes. The circuit is suitable for determining current source dynamic resistance and capacitance at low bias currents, and allows their values to be extracted from common-mode data by curve fitting. …”

Price Competition, Efficiency and Riskiness in Investment Banking by Radić, Nemanja, Fiordelisi, Franco, Girardone, Claudia

“…Our paper examines the intertemporal relationships between price competition, cost efficiency and riskiness for a sample of investment banks inten large developed countries over 2000-2008.We show that price competition is rather limited in investment banking worldwide thus implying the existence of colluding oligopolies.We also find that although investment banks’ stability was granted by relatively low competitive pressures, banks appeared prone to take more risk thus giving some support to the competition-stability view for the investment banking industry.…”

Long memory and fractional integration in high frequency financial time series by Caporale, Guglielmo Maria, Gil-Alana, Luis A.

“…Fractional integration or I(d) models are estimated with a variety of specifications for the error term. In brief, we find evidence that a lower degree of integration is associated with lower data frequencies. …”

EU banks rating assignments: is there heterogeneity between new and old member countries? by Caporale, Guglielmo Maria, Matousek, Roman, Stewart, Chris

“…We model EU countries' bank ratings using financial variables and allowing for intercept and slope heterogeneity. We find that country-specific factors (in the form of heterogeneous intercepts) are a crucial determinant of ratings. …”
