Background and aims

The aim of this research was to investigate the relationship between alexithymia and loss-chasing behavior in people at risk and not at risk for problem gambling.

Methods

An opportunity sample of 58 (50 males and 8 females) participants completed the Problem Gambling Severity Index and the Toronto Alexithymia Scale (TAS-20). They then completed the Cambridge Gambling Task from which a measure of loss-chasing behavior was derived.

Results

Alexithymia and problem gambling risk were significantly positively correlated. Subgroups of non-alexithymic and at or near caseness for alexithymia by low risk and at risk for problem gambling were identified. The results show a clear difference for loss-chasing behavior for the two alexithymia conditions, but there was no evidence that low and at-risk problem gamblers were more likely to loss chase. The emotion-processing components of the TAS-20 were shown to correlate with loss chasing.

Discussion and conclusion

These findings suggest that loss-chasing behavior may be particularly prevalent in a subgroup of problem gamblers those who are high in alexithymia.

Abstract  

A spectrophotometric method is described in which microgram amounts of plutonium can be determined in the presence of uranium, thorium, fission products and cladding materials. Plutonium is extracted with TTA in xylene and reextracted into a solution of Arsenazo III. Zirconium is masked by a Fe(III)-EDTA mixture, fluoride ions by Al(III). 2 to 40 μg of plutonium are required for one analysis. The standard deviation is 1.3% at 15 μg plutonium.

The crystal data of theα- andγ-modifications of KH(IO3)2 were determined. The rhombicβ-modification which has been described by earlier authors could not be obtained. In the course of thermal decomposition both crystal types release water, then I2O5 and O2, leaving a residue of KI. As an intermediate, K2I4O11 is formed. The temperatures of the DTA and DTG peaks of theα- andγ-modifications, were found to be different.

In this study a simple and effective method was developed for the isolation of Saccharomyces strains from grapes. Aseptically collected grape samples were processed by enrichment in a nutritive basal medium supplemented with 10% (v/v) methanol followed by isolation of yeast strains. Sixteen of the 18 grape samples yielded Saccharomyces strain(s). More than 70% of the isolates belonged to the genus Saccharomyces. Based on phenotype and electrophoretic karyotyping, all strains of Saccharomyces were identified as S. cerevisiae. For several grape samples, varying physiological characters, the number of spores per asci, and the observed chromosome length polymorphisms provided evidence for diversity of S. cerevisiae strains obtained by this enrichment in methanol-containing broth. Results indicated that enrichment in methanol-containing broth is an effective alternative method to facilitate isolation of Saccharomyces strains from grapes. The enrichment method described in this work provides a simple and effective tool for isolation of Saccharomyces strains from grapes. The method may be applied in studying wine fermentation ecology, as well as for the isolation of potential starter strains from grapes.

Abstract

In this paper we present different variants of the well-known Hermite–Hadamard inequality, in a generalized context. We consider general fractional integral operators for h-convex and r-convex functions.

Az angliai Committee for Quality Improvement anyagi támogatást nyújt azon sürgősségi osztályoknak, ahol a felnőtt, szeptikusnak véleményezett betegek a beérkezéstől számított 1 órán belül kapnak széles spektrumú antibiotikumot és 30 ml/kg-os krisztalloidbolus-infúziót. A fentihez hasonló egyórás célkitűzés számos más európai országban, az Egyesült Államokban és Ausztráliában is meghatározó minőségi mutatóvá vált, ugyanakkor szinte megjelenésének pillanatában éles támadások kereszttüzébe került, ugyanis az ajánlást alátámasztó bizonyítékok egyrészt nem feltétlenül vonatkoztathatók a sürgősségi ellátásra, másrészt valószínűleg idejétmúltak. A jelen cikk szerzői szisztematikus áttekintést terveztek annak a kérdésnek a megválaszolására, hogy az 1 órán belül beadott, 30 ml/kg intravénás bolus krisztalloidinfúzió valóban jelent-e klinikai előnyt (a mortalitás vagy a kórházi ápolási idő tekintetében) felnőtt, sürgősségi osztályon diagnosztizált szeptikus betegek kezelése esetén. A kutatási protokollt a szerzők prospektív módon regisztrálták a PROSPERO-n. Két párhuzamos lépésben 5 elsődleges (Embase, CINAHL, Medline, PubMed és Cochrane Library) és több másodlagos adatbázist vettünk górcső alá a 2012 és 2019 közötti időszakban teljes szöveggel megjelent cikkek vonatkozásában. Amennyiben a kutatásnak sikerül minimum 15, az előre lefektetett beválogatási kritériumoknak megfelelő cikket azonosítani, a szerzők megkísérelnek egy fix- vagy randomeffektus-metaanalízist. Amennyiben ez nem lehetséges, Fisher-féle kombinált p-érték kerül kiszámításra, és narratív szintézis kerül közlésre. A sürgősségi keretek között végzett, magas szintű evidenciát produkáló kutatás segíthet annak a felnőtt szeptikus betegcsoportnak (valamint a pontos klinikai előnyöknek és/vagy iatrogén ártalmaknak) a beazonosításához, akiknek a kezelésében a 30 ml/kg bolus krisztalloidinfúzió klinikailag igazolt előnyöket eredményezhet.

The 1,200-m-deep Budaörs-1 borehole provided important data for our understanding of the stratigraphy and tectonic setting of the southern part of the Buda Hills. Although previous reports contained valid observations and interpretations, a number of open questions remained. The importance of this borehole and the unsolved problems motivated us to revisit the archived core. The new studies confirmed the existing stratigraphic assignment for the upper dolomite unit (Budaörs Dolomite Formation) as the dasycladalean alga flora proved its late Anisian to Ladinian age assignment. An andesite dike was intersected within the Budaörs Dolomite. U–Pb age determination performed on zircon crystals revealed a Carnian age (~233 Ma), and settled the long-lasting dispute on the age of this dike, proving the existence of a Carnian volcanic activity in this area after the deposition of the Budaörs Dolomite. Palynostratigraphic studies provided evidence for a late Carnian to early Norian age of the upper part of the lower unit (Mátyáshegy Formation). This result verified an earlier assumption and reinforced the significance of the tectonic contact between the upper unit (Budaörs Formation) and the lower unit (Mátyáshegy Formation). Based on structural observations and construction of cross sections, two alternative models are presented for the structural style and kinematics of the contact zone between the Budaörs and Mátyáshegy Formations. Model A suggests a Cretaceous age for the juxtaposition, along an E–W striking sinistral transpressional fault. In contrast, model B postulates dextral transpression and an Eocene age for the deformation. The latter one is better supported by the scattered dip data; however, both scenarios are considered in this paper as possible models.
