The long-term prognosis of epilepsy patients with medically treated over a period of eight years in Turkey.
OBJECTIVE:The aim of this study was to investigate the effect of demographic and clinical characteristics on temporal changes in seizure control and frequency in medically treated epilepsy patients to guide treatment modalities. METHODS:We retrospectively analyzed the association between clinical and demographic characteristics and seizure frequency in 1329 epilepsy patients who were followed up at an outpatient clinic for one to eight years, 2008-2015.. RESULTS:Younger age at first seizure (p = 0.0465) and a long disease duration (p = 0.0406) had a negative effect on seizure control in all the epilepsy patients. Febrile convulsions (FCs) (p > 0.0001), perinatal risk (PNR) (p > 0.0002), a family history of epilepsy (FHE) (p > 0.0016), antiepileptic drug (AED) use (p > 0.001), mental retardation (MR) (p > 0.001), and psychiatric disorders (p > 0.0478) were prognostic indictors of temporal changes in seizure frequency. The presence of PNR (p = 0.0416), age at onset of epilepsy (p = 0.034), central nervous system infection (CNSI) (p = 0.04), and AEDs number (p = 0.0282) were prognostic indicators of not remaining seizure free for one year. In those with partial epilepsy, a trauma history (p = 0.05), a longer epilepsy duration (p = 0.0057), and FHE (p = 0.0466) increased the frequency of seizures, whereas cerebrovascular event (CVE) history decreased the seizure frequency (p = 0.0413). In addition, FHE (p = 0.0438) and psychotic disorders (p = 0.0416) increased generalized seizures frequency. CONCLUSION:In all the epilepsy patients, a younger age at onset and longer duration of epilepsy were associated with a poor prognosis. The presence of PNR, age at onset of epilepsy, CNSI, and AEDs numbers were prognostic indicators of not remaining seizure free for one year. Increasing AEDs number was not effective in controlling seizures in partial epilepsy, but it was effective in controlling seizures in generalized epilepsy
Measuring Core Inflation for Turkey - Trimmed Means Approach
This paper is one of the the pioneers in measuring the core inflation for Turkey and uses the methodology developed by Bryan, Cecchetti and Wiggins II (1997). As the price change distributions are not normally distributed, weighted sample means are not the efficient estimators of inflation. In such leptokurtic distributions trimmed means provide statistically more efficient estimators of inflation. For the consumer prices, using historical data, the optimal trim is found to be 19 percent from the each tail of the cross sectional distribution and for the wholesale prices it is found to be 12 percent (percentage that minimizes MAD). Trimmed mean estimators of inflation move in line with the headline inflation in the long run, implying a potential use for future inflation forecasting.Core Inflation, Trimmed Mean Estimators, Turkey
Estimation of monetary policy preferences in a forward-looking model: a Bayesian approach. NBB Working Papers No. 129, 13 March 2008
In this paper, we adopt a Bayesian approach to estimating monetary policy preference parameters in a general equilibrium framework. We start out from the model presented by Smets and Wouters (2003) for the euro area, where, in the original set-up, monetary policy behaviour is described by an empirical rule. We abandon this way of representing monetary policy behaviour and instead assume that monetary policy authorities optimise an intertemporal quadratic loss function under commitment. We consider two alternative specifications for the loss function. The first specification includes inflation, the output gap and difference in the interest rate as target variables. The second loss function includes an additional wage inflation target. The weights assigned to the target variables in the loss functions, i.e. the preferences of monetary policy, are estimated jointly with the structural parameters in the model. The results imply that inflation variability remains the main concern of optimal monetary policy. In addition, interest rate smoothing and the output gap appear to be important target variables as well, albeit to a lesser extent. Comparing the marginal likelihood of the original Smets and Wouters (2003) model to our specification with optimal monetary policy indicates that the latter performs only slightly worse. Since we are faced with the time-inconsistency problem under commitment, we initialise our estimates by considering a pre-sample period of 40 quarters. This enables an empirical approach to the timeless perspective framework

Valiant Hearts ensimmÀisen maailmansodan kuvaajana : Historian simulaatio, elÀvöitys ja pelisuunnittelu videopelissÀ
Tutkielmani kÀsittelee Montpellier peliyhtiön 2014 valmistaman Valiant Hearts: The Great War -pelin historiaa ja pelintekijöiden pelisuunnittelun pÀÀtöksentekoa historian ja pelitutkimuksen keinoin. Asemoin tutkimuksessa Valiant Hearts -pelin aikansa kontekstiin ja tutkin 2000-luvulla peliteollisuudessa tapahtuneita muutoksia, jotka mahdollistivat pelin valmistamisen. TÀmÀn lisÀksi syvennyn pelintekijöiden ratkaisuihin hyödyntÀÀ historiallisia lÀhteitÀ ja analysoin, miten ensimmÀisestÀ maailmansodasta tehty historian tutkimus ja yhteistyö historioitsijoiden kanssa on vaikuttanut pelin kehitykseen. Valiant Hearts julkaistiin ensimmÀisen maailmansodan juhlavuotena 2014. Ajoituksen yhtenÀ tavoitteena oli levittÀÀ tietoisuutta ensimmÀisestÀ maailmansodasta nuoremmille sukupolville helpommin lÀhestyttÀvÀmmÀllÀ tavalla.
Tutkimukseni koostuu kahdesta pÀÀlinjasta. EnsimmÀinen pÀÀlinja keskittyy 2000-luvun alusta 2014 vuoden peliteollisuuden historiaan, minkÀ kautta tutkin Montpellier peliyhtiön pÀÀtöstÀ ryhtyÀ valmistamaan peliÀ ensimmÀisen maailmansodan teemoista. Montpellier otti haasteekseen esittÀÀ ensimmÀinen maailmansota uudella ja lÀhestyttÀvÀmmÀllÀ tavalla, samalla mukaillen historiallisia lÀhteitÀ ja aikansa tavoitteita luoda tietoa ensimmÀisen maailmansodan vaikutuksista ja sodan kokeneiden yksilöiden elÀmÀstÀ. Tutkimuksessani argumentoin, ettÀ pelintekijöiden teknillisiin pÀÀtöksiin on selvÀsti vaikuttanut vuonna 2009 jÀrjestetty International Society for First World War Studies (ISFWWS) -konferenssi. Tutkimukseni toinen pÀÀlinja koostuu Valiant Hearts -pelin tarkastelusta kolmen pelihistorioitsijan luoman menetelmÀn avulla. TÀmÀ on mahdollistanut sekÀ pelin tarkemman tutkimisen, ettÀ miten pelintekijöiden peliteknilliset ratkaisut vÀlittÀvÀt tietoa menneisyydestÀ. Kyseiset kolme menetelmÀÀ ovat mahdollistaneet kattavan lÀhestymistavan tutkia ja arvioida Valiant Hearts -peliÀ historian simulaationa, elÀvöityksenÀ ja ongelmatilanteiden luojana. TÀmÀn avulla olen tutkielmassani syventynyt pelintekijöiden tavoitteiden analysoimiseen ja niiden vaikutukseen pelaajalle. LisÀksi nÀitÀ kolmea menetelmÀÀ hyödyntÀmÀllÀ olen osoittanut miten pelintekijöiden ratkaisut ovat vÀlittyneet pelaajalle ja miten ne luovat menneisyyden esitystÀ juuri tÀssÀ kyseisessÀ pelissÀ.
Olen tutkimuksessani avannut niitÀ tapoja, joilla Valiant Hearts esittÀÀ historiaa ja erityisesti mitkÀ eri pelitekniset ratkaisut vaikuttivat tuon menneisyyden esittÀmiseen. TÀmÀn lisÀksi tutkielmani osoittaa peliteollisuudella olleen vahvan vaikutuksen Valiant Hearts-pelin kehitykseen ja taiteellisiin lopputuloksiin, jotka kumpusivat sekÀ Montpellier peliyhtiön työntekijöiden omista mielenkiinnoista, ettÀ historiallisista referensseistÀ. Tutkimukseni osoittaa, ettÀ Valiant Hearts -pelintekijöiden tavoitteista löytyi huomattavia yhtenÀisyyksiÀ 2010-luvun ensimmÀisen maailmansodan tutkimusnÀkökulmiin ja lÀhestymistapoihin. NÀillÀ on pyritty korostamaan sekÀ pelin opettavaista puolta, ettÀ 100-vuotisjuhlan tavoitteita vÀlittÀÀ sodan vaikutuksia ja sen herÀttÀmiÀ tunteita

Amyloid peptide mixtures: self-assembly, hydrogelation, nematic ordering and catalysts in aldol reactions
Morphological, spectroscopic and scattering studies of the self-assembly and aggregation process of mixtures of [RF]4 and P[RF]4 peptides (where: R = arginine; F = phenylalanine; P = proline), in solution and as hydrogels, were performed to obtain information about polymorphism. CD data confirmed a ÎČ-sheet secondary structure conformation for the solutions and TEM images revealed nanofibers with diameters of ~ 10 nm and micrometer lengths. SAXS curves were fitted using a mass fractal-component and a long cylinder shell form factor for the liquid samples, and only a long cylinder shell form factor for the gels. Increasing the P[RF]4 content in the systems leads to a reduction in cylinder radius and core density scattering, suggesting an increase in packing of the peptide molecules; however, the opposite effect was observed for the gels. Remarkably, the gels are birefringent, indicating nematic ordering of the gel fibrils. These compounds show potential as catalysts in the asymmetric aldol reactions, with cyclohexanone and p-nitrobenzaldehyde in aqueous media. A moderate conversion (36.9 %) and a good stereoselectivity (69:31) were observed for the system containing only [RF]4, and with the increase of the P[RF]4, a considerable decrease of the conversion was observed, suggesting differences in the self-assembly and packing factor. Rheological measurements were performed to determine the shear moduli for the soft gels. These model amyloid peptides demonstrate a range of tunable self-assembly behaviors and additionally have potential as biocatalysts
