A new geoid model for Iran (IRG04) was computed based on the least squares modification of the Stokes formula. IRG04 was derived from the most recent gravity anomaly database, SRTM high resolution Digital Elevation Model (DEM) and GRACE GGM02 global geopotential model. In order to define a new height datum for Iran, we attempted to combine this high resolution gravimetric geoid model with GPS/levelling data using the corrective surface approach. The corrective surface was constructed from 224 GPS/levelling points and then evaluated with 35 independent points. Different interpolation techniques were tested for the creation of the corrective surface; among them the Kriging method was selected as it gave the smallest RMS and ‘noise level’ at the comparisons with GPS/levelling data. The RMS fit of the new combined geoid model versus the independent GPS/levelling data is 0.09 m, it is near four times better compared to the original gravimetric geoid model. The combined model should be more convenient and useful in definition of the new height reference surface, specifically in engineering and GPS/levelling projects.

Public health and social welfare subsystems are principally linked together by mutual interest in the basic care of elderly people. General practitioner (GP) services are parts of the social signaling system that promotes revealing unprovided needs. On the other hand, taking indigents into social care would make considerably easier the work of GPs. As a consequence, GPs' signaling should be a general practice everywhere. But social specialists experience the contrary. In order to explain the difference between the unity of interest in principle, and weak collaboration in reality, a theoretical model was elaborated and tested empirically. We have found that social service providers' preferences are not evident for GPs; therefore their willingness to signal depends on their opportunity of obtaining information.

CHAMP and GRACE global geopotential models EIGEN-3p, EIGEN-GRACE01S, GGM01S and GGM01C are compared with terrestrial gravity field data in Hungary. The methods used for comparison were direct comparison with gravity anomalies and the reference geoid solution method. We used free-air gravity anomalies interpolated on a 1' × 1.5' grid covering Hungary. In the second method these geopotential models were used to compute gravimetric geoid solutions and the results were compared with GPS/leveling data from EUVN campaign and the Hungarian GPS network.

Investigated is the relationship between the level of geomagnetic activity and the GPS TEC relative deviations from the monthly medians. Detailed information on this dependence is of crucial importance for developing a new synthetic index which, by quantifying the local response of TEC to geomagnetic activity, will be able to improve the quality of autocorrelation forecast procedures.</o:p>

Background and aims

The aim of this study was to test the screening properties of several combinations of items from gambling scales, in order to harmonize screening of gambling problems in epidemiological surveys. The objective was to propose two brief screening tools (three items or less) for a use in interviews and self-administered questionnaires.

Methods

We tested the screening properties of combinations of items from several gambling scales, in a sample of 425 gamblers (301 non-problem gamblers and 124 disordered gamblers). Items tested included interview-based items (Pathological Gambling section of the DSM-IV, lifetime history of problem gambling, monthly expenses in gambling, and abstinence of 1 month or more) and self-report items (South Oaks Gambling Screen, Gambling Attitudes, and Beliefs Survey). The gold standard used was the diagnosis of a gambling disorder according to the DSM-5.

Results

Two versions of the Rapid Screener for Problem Gambling (RSPG) were developed: the RSPG-Interview (RSPG-I), being composed of two interview items (increasing bets and loss of control), and the RSPG-Self-Assessment (RSPG-SA), being composed of three self-report items (chasing, guiltiness, and perceived inability to stop).

Discussion and conclusions

We recommend using the RSPG-SA/I for screening problem gambling in epidemiological surveys, with the version adapted for each purpose (RSPG-I for interview-based surveys and RSPG-SA for self-administered surveys). This first triage of potential problem gamblers must be supplemented by further assessment, as it may overestimate the proportion of problem gamblers. However, a first triage has the great advantage of saving time and energy in large-scale screening for problem gambling.

Introduction

The primary outcome of our study was to assess the links between the level of cognitive distortions and the severity of gambling disorder. We also aimed at assessing the links between patient gambling trajectories and attention deficit and hyperactivity disorder (ADHD).

Materials and methods

The study population (n = 628) was comprised of problem and non-problem gamblers of both sexes between 18 and 65 years of age, who reported gambling on at least one occasion during the previous year. Data encompassed socio-demographic characteristics, gambling habits, the South Oaks Gambling Screen, the Gambling Attitudes and Beliefs Survey – 23, the Wender Utah Rating Scale – Child, and the Adult ADHD Self-report Scale.

Results

The cognitive distortions with the greatest correlation to the severity of gambling disorder were the “Chasing” and “Emotions.” These two dimensions were able to distinguish between problem gamblers seeking treatment or not. While age of onset of gambling and length of gambling practice were not associated with the level of distorted cognitions, a period of abstinence of at least 1 month was associated with a lower level of distorted cognitions. The presence of ADHD resulted in a higher level of distorted cognitions.

Conclusion

Cognitive work is essential to the prevention, and the treatment, of pathological gambling, especially with respect to emotional biases and chasing behavior. The instauration of an abstinence period of at least 1 month under medical supervision could be a promising therapeutic lead for reducing gambling-related erroneous thoughts and for improving care strategies of pathological gamblers.

The propagation model for signal fluctuations on transionospheric radio links previously developed by the authors has been further extended to be capable of describing some new applications e.g. spatial coherency of the field, or the time-correlation properties of level (log-amplitude) and phase fluctuations and their frequency spectra. In particular, the technique has been developed to also generate random time sequences of the level and phase of the field on transionospheric paths of propagation. Spatial coherency is of importance for differential GPS in the assessment of the additional fluctuational errors in rangefinding with respect to a reference GPS station whereas random time series are necessary for modelling the fluctuational Earth-satellite channel of propagation.
