Dysfunctional beliefs about health and illness: a family study

2019

espanolLos modelos cognitivos sobre la hipocondria postulan que las experiencias tempranas con la enfermedad promueven el desarrollo de creencias disfuncionales sobre la enfermedad. Estas creencias pueden permanecer latentes y activarse ante un incidente critico. Los estudios publicados aportan datos que avalan de manera indirecta estos planteamientos. Teniendo en cuenta que en el nucleo familiar primario se comparten experiencias sobre la enfermedad, examinamos la relacion entre las creencias disfuncionales que los progenitores y sus descendientes mantienen sobre la enfermedad y los pensamientos, tales como la intolerancia a la incertidumbre y la sobreestimacion de la amenaza, y las relaci…

ACT for sleep - Internet-delivered self-help ACT for sub-clinical and clinical insomnia : A randomized controlled trial

2019

Background: Sleep disturbances are a common health problem. New and more accessible alternatives are needed to improve the availability of psychological treatments for insomnia. - Objective: The aim of the present study was to investigate the effects of a self-help Acceptance and Commitment Therapy-based web-intervention for sleep disturbances. - Method: Participants (N = 86) reporting symptoms of insomnia were randomly assigned to an Internet-delivered ACT (iACT, n = 43) or a control condition (WLC, n = 40) and assessed with standardized self-report measures related to sleep (ISI, BNSQ, ESS, DBAS), psychological symptoms (BDI-II, SCL-90), life satisfaction, and ACT-related processes (AAQ-2…

The negative interpretation of body sensations (e.g., as sign of a severe illness) is a crucial cognitive process in pathological health anxiety (HA). However, little is known about the nature and the degree of automaticity of this interpretation bias. We applied an implicit association test (IAT) in 20 subjects during functional magnetic resonance imaging (fMRI) to investigate behavioral and neural correlates of implicit attitudes towards symptom words. On the behavioral level, body symptom words elicited strong negative implicit association effects, as indexed by slowed reaction times when symptom words were paired with the attribute “harmless” (incongruent condition) relative to a contro…

Obsessional and Eating Disorder-related Intrusive Thoughts: Differences and Similarities Within and Between Individuals Vulnerable to OCD or to EDs

2016

Unwanted intrusive cognitions constitute the normal variant of clinically significant intrusive cognitions found in disorders such as obsessive-compulsive disorder (OCD) and eating disorders (EDs). This study investigates whether individuals who are vulnerable to OCD or EDs experience more intrusions than people with no vulnerability to these disorders, and it examines the consequences of obsessional (OITs) and eating disorder (EDITs) intrusions in the same individuals, taking into account their susceptibility to OCD, EDs or neither of the two. From a sample of 922 participants, three groups were formed: risk of OCD (n = 92), risk of EDs (n = 41) and a no-risk group (n = 100). EDITs were mo…

An experimental study on the effect of systemic functional linguistics applied through a genre-pedagogy approach to teaching writing

2016

Abstract In the tradition of teaching English as a second language, there has been an increased interest in how functional language descriptions and understandings of genres may be used as resources for making meaning. The present study investigates what impact writing instruction that draws upon systemic functional linguistics (SFL) applied through a genre-pedagogy approach has on students’ ability to write argumentative essays. This includes explicit grammar instruction inspired by SFL, as well as instruction on text structure. The study uses a mixed-methods approach, with a quasi-experiment followed up by quantitative and qualitative analyses of the collected material. Statistical analys…

Modelling of Systems for Real

2016

Modelling and Programming are often used together in system development. However, typically there is a large difference between the handling of modelling parts and the handling of programming parts. This leads to the fact that the transition between the two is not easy, and important information is lost as well as extra information has to be provided when combining modelling and programming. This paper shows how modelling and programming could work together in system development.

Efficient Linear-Scaling Density Functional Theory for Molecular Systems

2013

Despite recent progress in linear scaling (LS) density function theory (DFT), the computational cost of the existing LS methods remains too high for a widespread adoption at present. In this work, we exploit nonorthogonal localized molecular orbitals to develop a series of LS methods for molecular systems with a low computational overhead. High efficiency of the proposed methods is achieved with a new robust two-stage variational procedure or by replacing the optimization altogether with an accurate nonself-consistent approach. We demonstrate that, even for challenging condensed-phase systems, the implemented LS methods are capable of extending the range of accurate DFT simulations to molec…

Influence of the exchange and correlation functional on the structure of amorphous InSb and In3SbTe2 compounds

2016

We have investigated the structural, vibrational, and electronic properties of the amorphous phase of InSb and In3SbTe2 compounds of interest for applications in phase change non-volatile memories. Models of the amorphous phase have been generated by quenching from the melt by molecular dynamics simulations based on density functional theory. In particular, we have studied the dependence of the structural properties on the choice of the exchange-correlation functional. It turns out that the use of the Becke-Lee-Yang-Parr functional provides models with a much larger fraction of In atoms in a tetrahedral bonding geometry with respect to previous results obtained with the most commonly used P…

The changes in age of peak swim speed for elite male and female Swiss freestyle swimmers between 1994 and 2012

2014

This study determined the age and its changes across years of peak swimming performance from 50 to 1,500 m freestyle. Data of 70,059 Swiss freestyle swimmers (33,725 women and 36,334 men) aged 10-40 years and competing from 50 to 1,500 m were analysed. The association between age and swimming speed of the annual ten fastest swimmers was investigated using single and multi-level hierarchical regression analyses. For women, age of peak swimming speed increased in 50 m from 18.9 (s = 2.3) to 20.4 (s = 4.2) years but decreased in 1,500 m from 25.0 (s = 13.1) (1996) to 18.1 (s = 3.7) years. For 100-800 m, age remained at 19.1 (s = 1.1), 19.3 (s = 1.1), 18.7 (s = 1.5) and 18.5 (s = 1.3) years, re…

1,3-Dipolar Cycloaddition Reactions of Indan-1-one Enamines across Arylnitrile Oxides Leading to Novel Cyclic Isoxazoline Derivatives

2013

Synthesis of a series of cyclic fused-isoxazolines has been accomplished by regioselective and diastereoselective 1,3-dipolar cycloaddition of 3-methylindan-1-one enamines (1a, 1b, 1c) and 3-phenylindan-1-one enamines (2a, 2b, 2c) to arylnitrile oxides (3d, 3e, 3f, 3g, 3h). The structure of the cycloadducts was elucidated by 1H and 13C NMR spectroscopy. The proposed regio- and stereochemistry of fused-compounds (4) and (5) has also been corroborated by two single-crystal X-ray diffraction studies carried out on 4-methyl-8b-morpholinyl-3-(p-tolyl)-4H-3a,8b-dihydroindeno[2,3-d]isoxazoline (4be) and 3-(p-anisyl)-4-phenyl-8b-pyrrolidinyl-4H-3a,8b-dihydroindeno[2,3-d]isoxazoline (5af) and by mea…
