Aerva lanata collected during summer, monsoon and winter were subjected to similar extraction conditions as well as sample application conditions on precoated silica 60F254 TLC plates. The plates were developed in ethyl acetate-toluene (7:3 v/v) in order to study the seasonal variation in HPTLC fingerprints. A similar procedure was also followed for the plant samples collected from three different states of India, in order to study the geographical variation. p-Hydroxybenzoic acid, used as reference standard for comparison with each sample, was observed in samples collected in all three seasons but in different concentrations. The compound was also observed in samples collected from Gujarat and Maharashtra, but was found to be absent in the sample from Kerala. The sample from Kerala showed a different compound at R F 0.74, having a λ max of 280 nm. This compound exhibited a spectrum very different from that of p-hydroxybenzoic acid having a λ max of 252 nm, which separates out at R F 0.73 on the plate. The proposed method was validated according to ICH guidelines in terms of linearity, accuracy and specificity, intra-day and inter-day precision, repeatability of measurement of peak area, repeatability of sample application and specificity. The calibration graph was found to be linear over a range of concentration of 25.0–175.0 ng, with a regression coefficient of 0.9986. Determination of accuracy by standard addition method at three different concentration levels returned a mean recovery value of 97.24 ± 7.36. Intra-day and inter-day precision values were found to be less than 2%. The relative standard deviations (RSDs) of repeatability of sample application and measurement of area were found to be 1.24% and 0.93%, respectively.

Abstract  

Measurements of 222Rn (“radon”) in the environment are important in the geosciences and radiation-protection fields. We demonstrate here a simple laboratory-based calibration system to evaluate the efficiency of radon detectors with a reproducibility of about ±2%. The system uses a closed-loop air circulation design with 226Ra adsorbed onto MnO2-impregnated fiber as a radon source. Two RAD7 radon detectors (Durridge Co., Inc.) that were precisely calibrated at Durridge’s in-house calibration facility are used as secondary standards. By parallel analysis of the radon-enriched air within the closed loop, the test RAD7s are assigned a calibration coefficient to be applied to future measurements. We also performed a side-by-side intercomparison with two RAD7s in a high-radon natural environmental setting (limestone cave in Florida) that produced comparable results.

In this paper I examine the behaviour of Hungarian copular environmental constructions, and I demonstrate that they cannot be treated on a par with weather verbs (as suggested in the literature). While the latter may have a quasi-argumental subject, treating the former along the same lines would also mean to analyse the NP/AP featuring in these constructions as a predicate nominal/adjective. A parallel analysis of sentences involving nominal predication, environmental copular constructions and sentences with undisputable NP-subjects shows that environmental constructions pattern with the latter. I discuss and weigh the subject properties and the predicate properties of the nominal part of the construction, surveying all the evidence that has emerged in the literature, and adding some further arguments. The dual behaviour of the nominal/adjectival part of atmospheric copular constructions is argued to come from their predicative content combined with their status as syntactic subjects. For what appears to be an AP+ VAN ‘be’ type of environmental copular construction, an Adj → N conversion analysis is proposed, and an alternative analysis with the AP being the modifier of an abstract null noun is also mentioned.

Abstract:

Although belief narratives and charms are regarded as two different folklore genres with different modes of transmission, performance and function, they are both in a constant dialectical relationship, yielding mutual feedback. One of the main forms of this interactive relationship concerns the etiology of a dis-ease (construction of a dis-order, i.e. belief narratives) and its therapeutic treatment (restoration of order, i.e. charms). This relationship between the cause of diseases and their treatment is clearly reflected in a Christian content belief narrative closely associated with incantations used to heal abdominal diseases. The basic personage embodying this belief narrative – registered in many and different areas of Greece – is the figure of a monk or Christ himself, who, often disguised as a beggar, is hosted by a family. Violations of both religious norms associated with fasting and social ethics connected with accepted behaviour towards a guest have as a result the manifestation of an abdominal disease, which eventually the monk or Christ treats using an incantation. This article shows that the parallel analysis of legends and charms, where possible, is necessary since it can provide useful information, not only on the ways by which the charm text is produced and reproduced, but also on the position and status of the genre in the context of a wider folk religious system. Furthermore, it could contribute to the understanding of the charm text, without which the knowledge of the belief narrative is often incomprehensible, if not nonsensical.

A new concept, the flowing eluent walls (FEW) process, for segmentation of a non-segmented adsorbent bed, has been used for single- and multi-channel on-line overpressured-layer chromatography (OPLC). The FEW process leads to active and non-active regions on the adsorbent layer during the separation process. Mobile phase only is introduced to the non-active part of the layer whereas mobile phase and sample can be admitted to the active part, thus the non-homogeneous part of the adsorbent bed can be excluded from the separation process. The FEW configurations at the inlet side (FEW-I) eliminate the edge effect of OPLC in single-sample injections and the effect of sample-mixing between neighboring lanes in multi-channel separations. The FEW arrangements at the inlet and outlet sides (FEW-I/O) enable separate detection and collection of the components of the separation, and FEW lines solve the problems of joint detection of sample components and contaminants originating from the sealing material. One-channel OPLC with the FEW configuration is suitable for rapid isolation in different preparative ranges. Analytical and preparative TLC plates (20 cm × 20 cm) can be loaded with 5–25 mg and 25–125 mg, respectively. The multi-channel solution will be a tool for high-throughput analysis using efficient fine, superfine, or monolithic layers. The four and eight-channel versions can be used for high-throughput parallel analysis and for micro-preparative parallel isolation. The FEW concept provides the possibility of real multi-channel liquid chromatographic separation on a non-segmented layer and column shaped adsorbent bed.

Háttér: A pszichózisra való sérülékenység feltárása és a korai intervenció a klinikai gyakorlat és a kutatások fontos részét képezik. A Mágikus Fogalomképzés Skála az egyik leggyakrabban alkalmazott önjellemző kérdőív, amelyet a pszichózisra való hajlam feltárására dolgoztak ki. Meglepő azonban, hogy a Mágikus Fogalomképzés Skála pszicho­ metriai jellemzőit klinikai mintán szinte alig vizsgálták. Célkitűzés: A tanulmány fő célja a Mágikus Fogalomképzés Skála faktorszerkezetének feltárása nagy elemszámú egyetemi hallgatói mintán (n = 1730) és pszichiátriai betegek (n = 319) körében. Módszerek: A kérdőív faktorszerkezetét megerősítő (egydimenziós, többdimenziós szerkezet, bifaktoros elrendezés) és feltáró faktorelemzések, valamint parallel­elemzések segítségével vizsgáltuk. A skálák megbízhatóságát a hagyományos módszerek mellett (pl. Cronbach­α) modellalapú megbízhatósági becslésekkel (hierarchikus ómega) is jellemeztük. A faktorszerkezet elemzését követően a valószínűségi tesztelméleti alapokon nyugvó Tétel­válasz elmélet (Item Response Theory, IRT) segítségével az item­paraméterek becslését (nehézség és diszkrimináció) és az eltérő tételműködést is megvizsgáltuk, majd egy rövid, 15 tételes változatot alakítottunk ki, amelynek a kritériumvaliditását más mérőeszközök felhaszná- lásával teszteltük (pl. Szkizotípia Személyiség Kérdőív rövid változat; Davis­féle Empátia Kérdőív). Eredmények: A parallel­elemzés a hallgatói mintán 3 faktort, míg a klinikai mintán 2 dimenziót valószínűsített. Mindkét minta esetében a negatív tételek önálló dimen ziót alkottak, amit járulékos faktornak tekintetve a későbbiekben nem elemeztünk. A megerősítő faktorelemzés a normatív hallgatói mintán a bifaktoros struktúrát támasztotta alá, ahol az általános faktor mellett két speciális dimenzió jelent meg: paranormális hiedelmek és mágikus okság/spiritualitás (RMSEA = 0,052; CFI = 0,993; TLI = 0,990). A klinikai mintán az egydimenziós szerkezet adta a legjobb illeszkedési mutatókat (RMSEA = 0,032; CFI = 0,970; TLI = 0,965). A 15 tételre rövidített skála jó pszichometriai jellemzőkkel rendelkezett, bár az IRT elemzés rávilágított arra, hogy néhány tétel eltérő jelentést hordoz a nemek (nők vs. férfiak) vagy a vizsgálati minta típusa (normatív vs. klinikai) szerinti összevetéskor. Következtetések: Eredményeink megerősítik, hogy a mágikus fogalomalkotás a klinikai mintán egydimenziós modellel ragadható meg leginkább, ezzel szemben a normatív hallgatói mintán már inkább egy bifaktoros struktúra valószínűsíthető, amelynek két speciális dimenziója az adaptív (mágikus okság/spiritulaitás) és maladaptív (paranormális hiedelmek) sajátosságok mentén különül el.

Background: Study of vulnerability to psychosis and early intervention is an area of great clinical impact and research. The Magical Ideation Scale (MIS) is among the most widely used instruments for the assessment of psychosis proneness. However, there has been little research on the psychometric properties of the MIS in clinical sample. Aims: The main goal of the present work was to study the dimensional structure underlying the MIS in a large sample of students (n = 1.730) and clinical subjects (n = 319). Methods: The structures of the MIS were examined by confirmatory (e.g., single-factor model, model with second-order factor, bifactor model) and exploratory factor analysis and parallel-analysis. The internal consistencies were calculated not only in the conventional way (e.g. Cronbach’s α) but also in the controlling of the general factor (hierarchical omega, explained common variance). After initial testing, we used Item Response Theory (IRT) to shorten and further refine the instrument, and criterion validity was evaluated by other questionnaires (e.g. Schizotypy Personality Questionnaire – Brief Revised; Interpersonal Reactivity Index). Results: To determine the number of factors that can be applied, parallel-analysis provided a good estimation of the three dimensional structure of MIS in student sample and two dimensions in clinical subjects. However, the reversed worded items caused a method factor that does not appear to be substantively meaningful. Confirmatory factor analysis identified a bifactor solution (general scale and two specific scales: paranormal beliefs and magical reasoning/spirituality) for the MIS in student sample (RMSEA = 0.052, CFI = 0.993, TLI = 0.990), and a unidimensional factor structure in clinical sample (RMSEA = 0.032, CFI = 0.970, TLI = 0.965). The shortened 15-item version of the MIS has good psychometric properties, but few of the items displayed DIF across gender or type of sample (normative or clinical). Conclusions: Our results confirm that magical ideation can be considered as a single latent psychological variable on clinical sample, and a bifactorial structure in normative sample where the adaptive (magical reasoning/spirituality) and maladaptive (paranormal beliefs) functions separated.
