Errors sintàctics del gènere gramatical durant la cirurgia de gliomes cerebrals

Les bases neurals del processament sintàctic del gènere no han estat gairebé estudiades. En aquest estudi hem utilitzat el mapeig cerebral, durant la cirurgia de gliomes cerebrals per a estudiar les estructures cortico-subcorticals implicades en el processament del gènere i determinar si aquestes són comunes a altres àrees de la producció del llenguatge. Amb l’estimulació cerebral directa hem observat alteracions sintàctiques del gènere, al estimular la circumvolució frontal inferior, la part posterior circumvolució temporal mitja, i en el nucli caudat. També hem pogut observar, una doble dissociació entre el gènere gramatical i la producció de la paraula, corroborant les teories d’un model independent en la producció del llenguatge.

Recovering the Elliott invariant from the Cuntz semigroup

Let A be a simple, separable C*-algebra of stable rank one. We prove that the Cuntz semigroup of C (T, A) is determined by its Murray-von Neumann semigroup of projections and a certain semigroup of lower semicontinuous functions (with values in the Cuntz semigroup of A). This result has two consequences. First, specializing to the case that A is simple, finite, separable and Z-stable, this yields a description of the Cuntz semigroup of C (T, A) in terms of the Elliott invariant of A. Second, suitably interpreted, it shows that the Elliott functor and the functor defined by the Cuntz semigroup of the tensor product with the algebra of continuous functions on the circle are naturally equivalent.

The cognitive errors and coping patterns of child molesters as assessed by external observers: a pilot study

Cognitive errors (CE) and coping strategies (CS) are the focus of most cognitive-behavioral treatments for incarcerated child molesters. Several studies have reported differences in CEs and CSs between child molesters and controls. However, the vast majority of these studies assessed cognitive errors and coping using questionnaires, which are known to present a number of important limitations. This pilot study aimed to compare the CEs and CSs of N = 17 incarcerated child abusers and N = 12 controls using observer-rated methods, namely the Cognitive Error Rating Scale (CERS; Drapeau et al., 2005) and the Coping Action Pattern Rating Scale (CAPRS; Perry, Drapeau, & Dunkley, 2005). Results showed that child molesters presented more cognitive errors, in particular positive selective abstraction, and lower coping functioning, such as escape strategies. Treatment and research implications, including the use of observer-rated methods, are discussed.

Change in cognitive errors and coping over the course of brief psychodynamic intervention.

OBJECTIVE: Cognitive change over the course of psychodynamic psychotherapy has been postulated by several models, but has rarely been studied. Based on the adaptive skills model (Badgio, Halperin, & Barber, 1999), it is reasonable to expect that very brief dynamic psychotherapy may be associated with change in coping patterns and cognitive errors (also known as cognitive distortions) y. METHOD: N = 50 outpatients presenting with various psychiatric disorders and undergoing 4 sessions of Brief Psychodynamic Intervention (BPI; Despland, Drapeau, & de Roten, 2005; Despland, Michel, & de Roten, 2010) were included in this naturalistic study (mean age: 31 years; 56% female; all Caucasian). Cognitive errors and coping strategies were assessed using the Cognitive Errors Rating Scale (Drapeau et al., 2008) and Coping Patterns Rating Scale (Perry et al., 2005). These observer rated methods were applied to the verbatim transcriptions of all 4 therapy sessions completed by each patient. RESULTS: Results indicate change in both cognitive errors and coping patterns over the course of BPI, including an increase in the Overall Coping Functioning and a decrease in unhelpful coping processes, such as isolation, which reflects a shift in participant appraisal towards stress appraised as a challenge at the end of treatment. These changes predicted symptom change at the end of treatment. While cognitive errors also changed over the course of BPI, no predictive effect was found with regard to symptom change. CONCLUSIONS: These results are interpreted within the framework of common change principles in psychotherapy. Implications and future research are discussed.

Dix erreurs a ne pas commettre lors de la prise en charge d'une prothèse articulaire infectée en orthopédie [Ten errors to avoid while dealing with infected total joint arthroplasties].

Infections after total joint arthroplasty are rare but come with severe consequences. Timely, adequate and standardized treatment beginning at the onset of symptoms will have a major impact on the handling of this dreaded complication. In absences of clear guidelines, errors are often committed, with occasionally severe consequences for the patient. In this article, the 10 most frequent errors starting with diagnostics till antibiotic and surgical treatment will be discussed.

Recovering Euclidean deformable models from stereo-motion

In this paper we present a novel structure from motion (SfM) approach able to infer 3D deformable models from uncalibrated stereo images. Using a stereo setup dramatically improves the 3D model estimation when the observed 3D shape is mostly deforming without undergoing strong rigid motion. Our approach first calibrates the stereo system automatically and then computes a single metric rigid structure for each frame. Afterwards, these 3D shapes are aligned to a reference view using a RANSAC method in order to compute the mean shape of the object and to select the subset of points on the object which have remained rigid throughout the sequence without deforming. The selected rigid points are then used to compute frame-wise shape registration and to extract the motion parameters robustly from frame to frame. Finally, all this information is used in a global optimization stage with bundle adjustment which allows to refine the frame-wise initial solution and also to recover the non-rigid 3D model. We show results on synthetic and real data that prove the performance of the proposed method even when there is no rigid motion in the original sequence

Estratègies i errors en la resolució de problemes d'extrems per mètodes elementals

Aquesta investigació s’engloba dins del camp de la resolució de problemes en educació matemàtica i se centra en estudiar de quina manera els alumnes de primer curs de Batxillerat de dos instituts públics de Catalunya resolen alguns problemes d’extrems per mètodes elementals, és a dir, sense utilitzar les tècniques del càlcul diferencial. Tanmateix, s’estudia el punt de partida d’aquests alumnes davant dels problemes de màxims i mínims i es detecten algunes estratègies i diversos errors que cometen a l’hora de resoldre’ls. L’instrument de recollida de dades és un qüestionari individual que combina problemes d’extrems de resposta tancada amb altres problemes de resposta oberta. Es realitza una anàlisi inductiva – deductiva de les dades, la qual permet determinar que una part important dels participants en la recerca confonen les relacions entre l’àrea i el volum d’algunes figures geomètriques. A més, la majoria dels alumnes d’aquesta investigació resolen els problemes d’extrems plantejats fent ús de l’estratègia de conjecturar. Finalment, es detecta que diverses respostes dels participants presenten errors causats per l’ús de teoremes i/o de definicions matemàtiques equivocades. Aquest és el cas d’una aplicació errònia del teorema de Pitàgores, la confusió del perímetre d’un quadrat amb la longitud del seu costat i la determinació incorrecta de l’altura de diversos paral·lelograms.

Training effects with the observer-rated cognitive errors and the coping action patterns scales

The use of observer-rated scales requires that raters be trained until they have become reliable in using the scales. However, few studies properly report how training in using a given rating scale is conducted or indeed how it should be conducted. This study examined progress in interrater reliability over 6 months of training with two observer-rated scales, the Cognitive Errors Rating Scale and the Coping Action Patterns Rating Scale. The evolution of the intraclass correlation coefficients was modeled using hierarchical linear modeling. Results showed an overall training effect as well as effects of the basic training phase and of the rater calibration phase, the latter being smaller than the former. The results are discussed in terms of implications for rater training in psychotherapy research.

Validation study of the French version of the observer-rater scales measuring coping and cognitive errors (CE-CAP) on a non-clinical population

This study examined the validity and reliability of the French version of two observer-rated measures developed to assess cognitive errors (cognitive errors rating system [CERS]) [6] and coping action patterns (coping action patterns rating system [CAPRS]) [22,24]. The CE measures 14 cognitive errors, broken down according to their valence positive or negative (see the definitions by A.T. Beck), and the CAP measures 12 coping categories, based on an comprehensive review literature, each broken down into three levels of action (affective, behavioural, cognitive). Thirty (N = 30) subjects recruited in a community sample participated in the study. They were interviewed according to a standardized clinical protocol: these interviews were transcribed and analysed with both observer-rated systems. Results showed that the inter-rater reliability of the two measures is good and that their internal validity is satisfactory, due to a non-significant canonical correlation between CAP and CE. With regard to discriminant validity, we found a non-significant canonical correlation between CAPRS and CISS, one of most widely used self-report questionnaire measuring coping. The same can be said for the correlation with a self-report questionnaire measuring symptoms (SCL-90-R). These results confirm the absence of confounds in the assessment of cognitive errors and of coping as assessed by these observer-rated scales and add an argument in favour of the French validation of the CE-CAP rating scales.
