Treasures from UCL

UCL has one of the foremost university Special Collections in the UK. It is a treasure trove of national and international importance, comprising over a million items dating from the 4th century AD to the present day. Treasures from UCL draws together detailed descriptions and images of 70 of the most prized individual items. Between the magnificent illuminated Latin Bible of the 13th century and the personal items of one of the 20th century’s greatest writers, George Orwell, the many highlights of this remarkable collection will delight and intrigue anyone who picks up this book

Health Phones: A Potential Game Changer in Health Information Management

Health education has to be one of the most effective ways to reduce morbidity and mortality in developing countries. We need to deliver vital messages and information to people at the lower quarter of the society to use changing behaviour and practices which can save and protect their lives. It is in this context, use of mobile phones in delivering vital health information is of significance. This article reviews few projects which successfully use mobile phones for health information delivery

Keeping conceptualizations simple: Examples with family carers of people with dementia

This paper forms the second in a series of three articles on conceptualizations of older people's distress. The focus is on simple and concrete "mini-formulations" that keep the amount of information in them to a minimum, yet retain explanatory and predictive power. Such formulations can be used as the basis for action plans for intervention, while avoiding overburdening the cognitive capacity of the client or therapist. Simple linear and cyclical models are described, as are cognitive triad and dyad models. The uses of "mini-formulations" for group and individual settings are illustrated in a case example of a lady caring for her husband who has dementia

SPIT IN MY MOUTH: Queer Intimacies, Material Intra-actions, and Sensuous Becoming

This document describes my multidisciplinary art practice as it intersects with New Materialism, Queer and Affect theory, Ecology, and my embodied and experiential knowledge as a queer subject. The writing is divided into two categories. One is more theoretical, thinking through these different discourses. The other realizes them through relationships and intra-actions between my material kin and me. With these two modes of writing,I propose that embodied and felt knowing is as valid and illuminating as more traditional forms of knowledge. These sections are interdependent and resist linear logic, offering relational meanings to each reader as they find their way through a terrain of text and image offering a multiplicity of readings. Renaming difficulties with articulation as a legitimate tension within my own way of thinking and experiencing, this document pushes against such exactitude of ideas. Ultimately the artworks in my thesis exhibition and this outlining document work to reveal queerness, or queering, as a basic tenet for existence. This text uses Open Dyslexic, an open-source font designed for readers with dyslexia, a learning difference whose wide range of effects alters the way a person takes in, processes, and utilizes language and graphic symbols

Real exchange rates in latin america: The ppp hypothesis and fractional integration

This paper tests for PPP in a group of seventeen Latin American (LA) countries by applying fractional integration techniques to real exchange rate series. Compared to earlier studies on these economies, this approach has the advantage of allowing for non-integer values for the degree of integration, and thus for the possibility of PPP not holding continuously but as a long-run equilibrium condition. Further, breaks in the series are endogenously determined using a procedure based on the least-squares principle. This is particularly crucial in the Latin American countries, which have been affected by several exchange rate crises and policy regime changes. The results, based on different assumptions about the underlying disturbances, are in the majority of cases inconsistent with PPP, even more so when breaks are incorporated: Argentina is the only country for which clear evidence of mean reversion is found in the model including a break, albeit only in the second subsample

Stock market and economic growth: Evidence from three CEECs

This paper estimates a bivariate VAR-GARCH(1,1) model to examine linkages between stock market and economic growth in three CEEC countries (the Czech Republic, Hungary and Poland). The empirical findings suggest that there is unidirectional causality running from stock markets to growth in the levels, this linkage becoming stronger following the EU accession, which appears to be beneficial, presumably as a catalyst for institutional building and development. The same holds in most cases for volatility spillovers as well. In addition, Germany is confirmed to act as a locomotive for these countries, and a tight monetary policy is found to affect both economic and stock market growth adversely

Stock prices and monetary policy: An impulse response analysis

This paper analyses the relationship between monetary policy and the stock market with the aim of gaining new insights into the transmission mechanism of monetary policy. The empirical findings shed light on the importance of stock prices for money demand and therefore provide useful nformation to monetary authorities deciding on policy actions. A technique developed by Wickens and Motto (2001) for identifying shocks by estimating a VECM for the endogenous variables is employed. The reported evidence suggests that stock markets play a significant role in the money demand function

Stock market integration between three CEECs

This paper estimates a trivariate VAR-GARCH(1,1) model to examine volatility linkages between the stock markets of three Central and Eastern European countries (CEECs), namely the Czech Republic, Hungary and Poland. The empirical findings suggest that following the EU accession regional linkages have become even stronger, and that therefore portfolio diversification within the region has become an even less effective investment strategy. This can be plausibly interpreted as reflecting deeper integration with the "old" EU economies, and has important implications for appropriate policy responses to shocks originating in those countries and affecting the financial stability of the CEECs

Valuing American Put Options Using Chebyshev Polynomial Approximation

This paper suggests a simple valuation method based on Chebyshev approximation at Chebyshev nodes to value American put options. It is similar to the approach taken in Sullivan (2000), where the option`s continuation region function is estimated by using a Chebyshev polynomial. However, in contrast to Sullivan (2000), the functional is fitted by using Chebyshev nodes. The suggested method is flexible, easy to program and efficient, and can be extended to price other types of derivative instruments. It is also applicable in other fields, providing efficient solutions to complex systems of partial differential equations. The paper also describes an alternative method based on dynamic programming and backward induction to approximate the option value in each time period

Non-normality and recursive unit root test for PPP: Solving the PPP puzzle?

In this paper we carry out unit root tests on real exchange rates recursively as in Caporale et al (2003), but, following Arghyrou and Gregoriou (2007), we adjust the residuals for non-normality using a wild bootstrap method. The results are striking: the correction for non-normality dramatically increases the rejection percentages of the unit root null, and attenuates the erratic behaviour of the t-statistic, thus providing strong evidence in favour of PPP, and suggesting that such a correction might at least go some way towards solving the “PPP puzzle”
