Spatial and Temporal Diffusion of House Prices in the UK

This paper provides a method for the analysis of the spatial and temporal diffusion of shocks in a dynamic system. We use changes in real house prices within the UK economy at the level of regions to illustrate its use. Adjustment to shocks involves both a region specific and a spatial effect. Shocks to a dominant region - London - are propagated contemporaneously and spatially to other regions. They in turn impact on other regions with a delay. We allow for lagged effects to echo back to the dominant region. London in turn is influenced by international developments through its link to New York and other financial centers. It is shown that New York house prices have a direct effect on London house prices. We analyse the effect of shocks using generalised spatio-temporal impulse responses. These highlight the diffusion of shocks both over time (as with the conventional impulse responses) and over space.House Prices, Cross Sectional Dependence, Spatial Dependence

Long Run Macroeconomic Relations in the Global Economy

This paper focuses on testing long run macroeconomic relations for interest rates, equity, prices and exchange rates within a model of the global economy. It considers a number of plausible long run relationships suggested by arbitrage in financial and goods markets, and uses the global vector autoregressive (GVAR) model in Dees, di Mauro, Peseran and Smith (2007) to test for long run restrictions in each country/region conditioning on the rest of the world. Bootstrapping is used to compute both the empirical distribution of the impulse responses and log-likelihood ratio statistic for over-identifying restrictions. The paper also examines the speed with which adjustments to the long tun relations take place via the persistence profiles. We find strong evidence in favour of the uncovered interest parity and to a lesser extent the Fisher equation across a number of countries, but our results for the PPP are much weaker. Also as to be expected, the transmission of shocks and subsequent adjustments in financial markets are much faster than those in goods markets

Kinetika neizotermne kristalizacije kalkogenidnog stakla Sb10Ge10Se80

A differential scanning calorimetry technique was used to study the crystallization kinetics of Sb10Ge10Se80 chalcogenide glass under non-isothermal conditions. The crystallization parameters such as the order parameter (n), the frequency factor (k0), the activation energy of crystallization (Ec), the activation energy of glass transition (Eg) and the activation energy of nucleation (En) were determined. The value of Ec was deduced by means of six methods and the average value was found to be equal to (76.10±1.10) kJmol−1 . The most suitable method for crystallization kinetic studies was the Augis–Bennett approximated method at different heating rates, while the method of Coats–Redfern–Sestak was the most suitable one at constant heating rate. The results have been discussed on the basis of theoretical principles.Primijenili smo diferencijalnu pretražnu kalorimetriju za proučavanje kinetike kristalizacije kalkogenidnog stakla Sb10Ge10Se80 u neizotermnim uvjetima. Odredili smo sljedeće parametre kristalizacije: parametar reda (n), faktor frekvencije (k0), aktivacijsku energiju kristalizacije (Ec), aktivacijsku energiju staklenog prijelaza (Eg) i aktivacijsku energiju nukleacije. Ec smo izveli na osnovi šest metoda i našli srednju vrijednost (76.10 ± 1.10) kJmol−1 . Najpogodnija metoda za proučavanje kinetike kristalizacije za različite brzine grijanja je Augis–Bennettova približna metoda, dok se metoda Coats–Redfern–Sestak-a pokazala najbolja za stalnu brzinu grijanja.

Analysis of a laterally loaded rigid cylinder embedded in an elastoplastic

An analytical approach has been developed to predict the response of a rigid disc embedded in elastoplastic media. The governing differential equations are obtained using the principle of minimizing the potential energy. The displacement components in cylindrical coordinates could be represented by Fourier series. The fitted method is used to determine the Fourier series harmonic coefficients. Validation is made against finite element analysis and previously published solutions

THE IMPACT OF DETRAINING ON PERFORMANCE AND SOME OF THE BIOMECHANICAL VARIABLES IN TAEKWONDO

Twenty players (aged 9 – 13 yrs) were divided into two equivalent groups ( 10 each ) based on ( age , height , weight , training age and the selected biomechanical variables).The 1st group ( fixed training) trained by the round house kick from ready position (stance) while the 2nd group ( variant training ) trained using different types of the skills’ execution. Both group trained there times a week (75 Minutes) for 6 weeks and measurements were taken for the post test, one week later of detraining and two weeks later of detraining, for fixed training and variant training. No significant differences were observed between the two groups in the posttest and first detraining. It is recommended that both training regimen are important to conserve the level of achieved performance after 2 weeks of detraining
