Velocity profiles of interplanetary shocks

The type 2 radio burst was identified as a shock propagating through solar corona. Radio emission from shocks travelling through the interplanetary (IP) medium was observed. Using the drift rates of IP type II bursts the velocity characteristics of eleven shocks were investigated. It is indicated that shocks in the IP medium undergo acceleration before decelerating and that the slower shocks take longer to attain their maximum velocity

Analysis of Purchasing power parity with data for Macedonia

This paper examines PPP parity theory with data for Macedonia. We test the empirical consensus in this literature that real exchange rates tend towards PPP in the very long run, also we use co-integration Engle-Granger method and error correction mechanism. The hypothesis we test that PPP theory holds in long run in the case of Macedonia, and this hypothesis is proven to be true.PPP, Exchange rate, Co-integration, unit root, stationarity

The causal relationship between patent growth and growth of GDP with quarterly data in the G7 countries: cointegration, ARDL and error correction models

This empirical study investigates the dynamic link between patent growth and GDP growth in G7 economies. ARDL model showed that there exist positive relationship in long run between quarterly growth of patents and quarterly GDP growth. The error correction term suggests that 20,6 percent of the adjustment back to long run equilibrium of industrial production in G7 countries is corrected by 20,6% a year, following a shock like the one in 1974 , which in our study is controlled by a dummy variable D74. In the short run however at one or two lags there exist negative relationship between quarterly patents growth and quarterly growth of GDP. Johansen’s procedure for cointegration showed that long run multipliers are positive between the patent growth and GDP growth in G7 economies. Granger causality test showed that patent growth Granger cause GDP growth in G7 countries. Unrestricted VAR showed that there exists positive relationship between patent growth and GDP growth at two or three lags.Cointegration, ARDL, Error correction models, Johasens’s procedure, Patent growth, GDP growth

Examining the cognitive costs of counterfactual language comprehension: Evidence from ERPs

Recent empirical research suggests that understanding a counterfactual event (e.g. ‘If Josie had revised, she would have passed her exams’) activates mental representations of both the factual and counterfactual versions of events. However, it remains unclear when readers switch between these models during comprehension, and whether representing multiple ‘worlds’ is cognitively effortful. This paper reports two ERP studies where participants read contexts that set up a factual or counterfactual scenario, followed by a second sentence describing a consequence of this event. Critically, this sentence included a noun that was either consistent or inconsistent with the preceding context, and either included a modal verb to indicate reference to the counterfactual-world or not (thus referring to the factual-world). Experiment 2 used adapted versions of the materials used in Experiment 1 to examine the degree to which representing multiple versions of a counterfactual situation makes heavy demands on cognitive resources by measuring individuals’ working memory capacity. Results showed that when reference to the counterfactual-world was maintained by the ongoing discourse, readers correctly interpreted events according to the counterfactual-world (i.e. showed larger N400 for inconsistent than consistent words). In contrast, when cues referred back to the factual-world, readers showed no difference between consistent and inconsistent critical words, suggesting that they simultaneously compared information against both possible worlds. These results support previous dual-representation accounts for counterfactuals, and provide new evidence that linguistic cues can guide the reader in selecting which world model to evaluate incoming information against. Crucially, we reveal evidence that maintaining and updating a hypothetical model over time relies upon the availability of cognitive resources

Supporting evidence-based adaptation decision-making in the Australian Capital Territory: a synthesis of climate change adaptation research

This research synthesis provides policy-makers and practitioners with an understanding of the building blocks for effective adaptation decision-making, as evidenced through the NCCARF research program. It synthesised a portfolio of adaptation research for each Australian state and territory and addressing the complex relationships between research and policy development.   Each state and territory synthesis report directs users to research relevant identified priorities.

The macroeconomic implication of exchange rate regimes

This study investigates the relation between macroeconomic variables such as real GDP growth, inflation, unemployment rate, trade deficit and the exchange regimes. The idea is to explore whether the macroeconomic indicators give better result when are under the influence of fixed or fluctuating exchange rates. In order to obtain relevant results, we took 5 countries with fixed and 5 countries with floating exchange rates. The paper also concerns the Macedonian exchange rate regimes. Here the focus is put on two periods. The first one is from 1993- 1995 when the country had fluctuating exchange rate. The second period is from 1995 till now -2011, when Macedonia has been implementing a regime of fixed "pegged" exchange rate.exchange rate, macroeconomic variables
