Tubal function in divers and non-divers: case control study
2009
Background. The aim of this study was to examine whether recurrent scuba diving during the time and frequent use of Valsalva’s manoeuvre while diving, increase functionality of divers’ Eustachian Tube (ET) comparison with non-divers. Methods. The study included 30 experienced divers (G1), mean age 25,8 years, who were diving from over 10 years. The control group consisted of 30 non-divers (G2), mean age 31,3 years. Each sample underwent clinical examination to identify predisposing conditions to middle ear barotraumas and ET dysfunction. ET function has been investigated by Inflation-Deflation test that shows baseline tympanogram, a second tympanogram shifted of the peak towards positive va…
Deflation-based separation of uncorrelated stationary time series
2014
In this paper we assume that the observed pp time series are linear combinations of pp latent uncorrelated weakly stationary time series. The problem is then to find an estimate for an unmixing matrix that transforms the observed time series back to uncorrelated time series. The so called SOBI (Second Order Blind Identification) estimate aims at a joint diagonalization of the covariance matrix and several autocovariance matrices with varying lags. In this paper, we propose a novel procedure that extracts the latent time series one by one. The limiting distribution of this deflation-based SOBI is found under general conditions, and we show how the results can be used for the comparison of es…
Deciphering the Macroeconomic Effects of Internal Devaluations in a Monetary Union
2020
We study the macroeconomic effects of internal devaluations undertaken by a periphery of countries belonging to a monetary union. We find that internal devaluations have large and positive output effects in the long run. Through an expectations channel, most of these effects carry over to the short run. Internal devaluations focused on goods markets reforms are generally more powerful in stimulating growth than reforms aimed at moderating wages, but the latter are less deflationary. For a monetary union with a periphery the size of the euro area's, the countries at the periphery benefit from internal devaluations even at the zero lower bound (ZLB) of the nominal interest rate. Nevertheless,…
Quine’s conflicts with truth deflationism
2022
AbstractCompared to the extensive amount of literature on various themes of W.V.O. Quine’s philosophy, his immanent concept of truth remains a relatively unexplored topic. This relative lack of research contributes to a persistent confusion on the deflationary and inflationary details of Quine’s truth. According to a popular reading, Quine’s disquotational definition of the truth predicate exhausts the topic of truth, thus amounting to a deflationary view. Others promote opposing interpretations. I argue that by relying on Tarski’s semantic conception of truth, Quine’s disquotational account inherits a commitment to classical correspondence intuitions. Based on this, Quine posits a firm con…
A Naïve Sticky Information Model of Households’ Inflation Expectations
2009
This paper provides a simple epidemiology model where households, when forming their inflation expectations, rationally adopt the past release of inflation with certain probability rather than the forward-looking newspaper forecast as suggested in Carroll [2003, Macroeconomic Expectations of Households and Professional Forecasters, Quarterly Journal of Economics, 118, 269-298]. The posterior model probabilities based on the Michigan survey data strongly support the proposed model. We also extend the agent-based epidemiology model by deriving for it a simple adaptation, which is suitable for estimation. Our results show that this model is able to capture the heterogeneity in households’ expe…
Deflation-Corrected Estimators of Reliability
2022
Underestimation of reliability is discussed from the viewpoint of deflation in estimates of reliability caused by artificial systematic technical or mechanical error in the estimates of correlation (MEC). Most traditional estimators of reliability embed product–moment correlation coefficient (PMC) in the form of item–score correlation (Rit) or principal component or factor loading (λi). PMC is known to be severely affected by several sources of deflation such as the difficulty level of the item and discrepancy of the scales of the variables of interest and, hence, the estimates by Rit and λi are always deflated in the settings related to estimating reliability. As a short-cut to deflation-c…
Global Food Prices and Domestic Inflation: Some Cross-Country Evidence
2015
We study the impact of global food price shocks on domestic inflation in a large group of countries. For advanced economies, a 10% increase in global food inflation raises domestic inflation by about 0.5 percentage point after a year; however, the impact has declined over time and become less persistent. The global food price shocks of the 2000s had a much bigger impact on domestic inflation in emerging and developing economies than in advanced economies. This could reflect the smaller share of food in the consumption baskets in advanced economies. We also provide evidence that inflation expectations are more anchored in advanced than in emerging economies, which could also explain the smal…
