Occasional adnominal idiom modification : a cognitive linguistic approach

abstract:occasional Adnominal Idiom Modification - A Cognitive Linguistic Approach From a cognitive-linguistic perspective, this paper explores alternative types of adnoniinal modification in occasional variants of English verbal idioms. Being discussed against data extracted from the British National Corpiis (BNC), the model claims that in idioni-production idiomatic constructions are activated as complex linguistic schemas to code a context-specific target-conceptualisation. Adnominal pre- and postmodifications are one specific form of creative alteration to adapt the idiom for this purpose. Semantically, idiom-interna1 NPextension is not a uniforni process. It is necessary to distinguish two systematic types of adnominal modification: external and internal modification (Ernst 1981). While external NPmodification has adverbial function, ¡.e. it modifies the idiom as a unit, internal modification directly applies to the head-noun and thus depends on the degree of motivation and analysability of a given idiom. Following the cognitive-linguistic framework, these dimensions of idiom-transparency result from the language user's ability to remotivate the bipartite semantic structure by conceptual metaphors and metonymies.

Hemispheric language asymmetry in first episode psychosis and schizotypy : the role of cannabis consumption and cognitive disorganization

Cannabis use has been related to an elevated psychosis risk and attenuated cognitive functioning. Cannabis-related cognitive impairments are also observed in populations along the psychosis dimension. We here investigated whether a potential behavioural marker of the psychosis dimension (attenuated functional hemispheric asymmetry) is even further attenuated in individuals using cannabis (CU) versus those not using cannabis (nCU). We tested 29 patients with first episode psychosis (FEP; 11 CU) and 90 healthy controls (38 CU) on lateralized lexical decisions assessing left hemisphere language dominance. In patients, psychotic symptoms were assessed (PANSS). In controls, self-reported schizotypy was assessed (O-LIFE questionnaire). Results indicated that nCU FEP patients had a relative reduced hemispheric asymmetry, as did controls with increasing cognitive disorganisation scores, in particular when belonging to the group of nCU controls. Positive, disorganised and negative PANSS scores in patients and negative and positive schizotypy in controls were unrelated to hemispheric asymmetry. These findings suggest that cannabis use balances rather than exacerbates uncommon hemispheric laterality patterns. Moreover, in healthy populations, the potential stabilisation of typical hemispheric asymmetry in CU might be most relevant to individuals with elevated cognitive disorganisation. We discuss the potential beneficial and harmful effects of cannabis use along the psychosis dimension together with propositions for future studies that should account for the mediating role of additional substances (e.g. nicotine), cannabis composition (e.g. cannabidiol content), and individual differences (e.g. physical health, or absence of significant polysubstance use).

Personality traits, behavioral and psychological symptoms and cognitive decline in patients at an early stage of Alzheimer's disease

The aim of this doctoral thesis was to study personality characteristics of patients at an early stage of Alzheimer's disease (AD), and more specifically to describe personality and its changes over time, and to explore its possible links with psychological and symptoms (BPS) and cognitive level. The results were compared to those of a group of participants without cognitive disorder through three empirical studies. In the first study, the findings showed significant personality changes that follow a specific trend in the clinical group. The profil of personality changes showed an increase in Neuroticism and a decrease in Extraversion, Openess to experiences, and Conscientiousness over time. The second study highlighted that personality and BPS occur early in the cours of AD. Recognizing them as possible precoce signs of neurodegeneration may prove to be a key factor for early detection and intervention. In the third study, a significant association between personality changes and cognitive status was observed in the patients with incipient AD. Thus, changes in Neuroticism and Conscientiousness were linked with cognitive deterioration, whereas decreased Openness to experiences and Conscientiousness over time predicted loss of independence in daily functioning. Other well-known factors such as age, education level or civil status were taken into account to predict cognitive decline. The three studies suggested five important implications: (1) cost-effective screening should take into account premorbid and specific personality changes; (2) psycho-educative interventions should provide information on the possible personality changes and BPS that may occur at the beginning of the disease; (3) using personality traits alongside other variables in the future studies on prevention might help to better understand AD's etiology; (4) individual treatment plans (psychotherapeutic, social, and pharmacological) might be adapted to the specific changes in personality profiles; (5) more researches are needed to study the impact of social-cultural and lifestyle variables on the development of AD.

Du principe de continuité de l'exploitation en comptabilité : contribution à la formalisation de la démarche cognitive du réviseur aux comptes dans la validation de ce principe à l'aide d'un système abductif de modélisation de croyance basé sur un processus stochastique

Résumé : J'ai souvent vu des experts être d'avis contraires. Je n'en ai jamais vu aucun avoir tort. Auguste Detoeuf Propos d'O.L. Brenton, confiseur, Editions du Tambourinaire, 1948. En choisissant volontairement une problématique comptable typiquement empirique, ce travail s'est attelé à tenter de démontrer la possibilité de produire des enseignements purement comptables (ie à l'intérieur du schème de représentation de la Comptabilité) en s'interdisant l'emprunt systématique de theories clé-en-main à l'Économie -sauf quant cela s'avère réellement nécessaire et légitime, comme dans l'utilisation du CAPM au chapitre précédent. Encore une fois, rappelons que cette thèse n'est pas un réquisitoire contre l'approche économique en tant que telle, mais un plaidoyer visant à mitiger une telle approche en Comptabilité. En relation avec le positionnement épistémologique effectué au premier chapitre, il a été cherché à mettre en valeur l'apport et la place de la Comptabilité dans l'Économie par le positionnement de la Comptabilité en tant que discipline pourvoyeuse de mesures de représentation de l'activité économique. Il nous paraît clair que si l'activité économique, en tant que sémiosphère comptable directe, dicte les observations comptables, la mesure de ces dernières doit, tant que faire se peut, tenter de s'affranchir de toute dépendance à la discipline économique et aux théories-méthodes qui lui sont liées, en adoptant un mode opératoire orthogonal, rationnel et systématique dans le cadre d'axiomes lui appartenant en propre. Cette prise de position entraîne la définition d'un nouveau cadre épistémologique par rapport à l'approche positive de la Comptabilité. Cette dernière peut se décrire comme l'expression philosophique de l'investissement de la recherche comptable par une réflexion méthodique propre à la recherche économique. Afin d'être au moins partiellement validé, ce nouveau cadre -que nous voyons dérivé du constructivisme -devrait faire montre de sa capacité à traiter de manière satisfaisante une problématique classique de comptabilité empirico-positive. Cette problématique spécifique a été choisie sous la forme de traitement-validation du principe de continuité de l'exploitation. Le principe de continuité de l'exploitation postule (énonciation d'une hypothèse) et établit (vérification de l'hypothèse) que l'entreprise produit ses états financiers dans la perspective d'une poursuite normale de ses activités. Il y a rupture du principe de continuité de l'exploitation (qui devra alors être écartée au profit du principe de liquidation ou de cession) dans le cas de cessation d'activité, totale ou partielle, volontaire ou involontaire, ou la constatation de faits de nature à compromettre la continuité de l'exploitation. Ces faits concernent la situation financière, économique et sociale de l'entreprise et représentent l'ensemble des événements objectifs 33, survenus ou pouvant survenir, susceptibles d'affecter la poursuite de l'activité dans un avenir prévisible. A l'instar de tous les principes comptables, le principe de continuité de l'exploitation procède d'une considération purement théorique. Sa vérification requiert toutefois une analyse concrète, portant réellement et de manière mesurable à conséquence, raison pour laquelle il représente un thème de recherche fort apprécié en comptabilité positive, tant il peut (faussement) se confondre avec les études relatives à la banqueroute et la faillite des entreprises. Dans la pratique, certaines de ces études, basées sur des analyses multivariées discriminantes (VIDA), sont devenues pour l'auditeur de véritables outils de travail de par leur simplicité d'utilisation et d'interprétation. À travers la problématique de ce travail de thèse, il a été tenté de s'acquitter de nombreux objectifs pouvant être regroupés en deux ensembles : celui des objectifs liés à la démarche méthodologique et celui relevant de la mesure-calibration. Ces deux groupes-objectifs ont permis dans une dernière étape la construction d'un modèle se voulant une conséquence logique des choix et hypothèses retenus.

Conduite automobile et troubles cognitifs: comment anticiper [Driving and cognitive impairment: how best to anticipate?].

Driving requires integrating multiple motor, sensory, and cognitive skills. As people age, cognition becomes increasingly vulnerable due to impairment and dementia. Older drivers suffering from dementia, even at an early stage, have been shown to be significantly more likely to develop unsafe driving. Primary care physicians have the difficult task to assess these persons' driving capacity. This paper briefly describes the consequences of altered cognition on driving capacity and proposes an algorithm to address this challenge.

Relation between sequence and structure of HIV-1 protease inhibitor complexes: a model system for the analysis of protein flexibility.

The flexibility of different regions of HIV-1 protease was examined by using a database consisting of 73 X-ray structures that differ in terms of sequence, ligands or both. The root-mean-square differences of the backbone for the set of structures were shown to have the same variation with residue number as those obtained from molecular dynamics simulations, normal mode analyses and X-ray B-factors. This supports the idea that observed structural changes provide a measure of the inherent flexibility of the protein, although specific interactions between the protease and the ligand play a secondary role. The results suggest that the potential energy surface of the HIV-1 protease is characterized by many local minima with small energetic differences, some of which are sampled by the different X-ray structures of the HIV-1 protease complexes. Interdomain correlated motions were calculated from the structural fluctuations and the results were also in agreement with molecular dynamics simulations and normal mode analyses. Implications of the results for the drug-resistance engendered by mutations are discussed briefly.

Stability of cognitive performance in children with mild intellectual disability.

AIM: Longitudinal studies that have examined cognitive performance in children with intellectual disability more than twice over the course of their development are scarce. We assessed population and individual stability of cognitive performance in a clinical sample of children with borderline to mild non-syndromic intellectual disability. METHOD: Thirty-six children (28 males, eight females; age range 3-19y) with borderline to mild intellectual disability (Full-scale IQ [FSIQ] 50-85) of unknown origin were examined in a retrospective clinical case series using linear mixed models including at least three assessments with standardized intelligence tests. RESULTS: Average cognitive performance remained remarkably stable over time (high population stability, drop of only 0.38 IQ points per year, standard error=0.39, p=0.325) whereas individual stability was at best moderate (intraclass correlation of 0.58), indicating that about 60% of the residual variation in FSIQ scores can be attributed to between-child variability. Neither sex nor socio-economic status had a statistically significant impact on FSIQ. INTERPRETATION: Although intellectual disability during childhood is a relatively stable phenomenon, individual stability of IQ is only moderate, likely to be caused by test-to-test reliability (e.g. level of child's cooperation, motivation, and attention). Therefore, clinical decisions and predictions should not rely on single IQ assessments, but should also consider adaptive functioning and previous developmental history.

Cognitive Predictors and Risk Factors of PTSD Following Stillbirth: A Short-Term Longitudinal Study.

This short-term longitudinal study investigated cognitive predictors and risk factors of posttraumatic stress disorder (PTSD) in mothers following stillbirth. After a stillbirth at ≥ 24 weeks gestational age, 65 women completed structured clinical interviews and questionnaires assessing PTSD symptoms, cognitive predictors (appraisals, dysfunctional strategies), and risk factors (perceived social support, trauma history, obstetric history) at 3 and 6 months. PTSD symptoms decreased between 3 and 6 months (Cohen's d ranged .34-.52). Regression analyses also revealed a specific positive relationship between Rumination and concurrent frequency of PTSD symptoms (β = .45). Negative Self-View and Negative World-View related positively and Self-Blame related negatively to concurrent number of PTSD symptoms (β = .48, .44, -.45, respectively). Suppression and Distraction predicted a decrease and Numbing predicted an increase in time-lagged number of PTSD symptoms (β = -.33, -.28, .30, respectively). Risk factors for PTSD symptoms were younger age (β = -.25), lower income (β = -.29), fewer previous pregnancies (β = -.31), and poorer perceived social support (β = -.26). Interventions addressing negative appraisals, dysfunctional strategies, and social support are recommended for mothers with PTSD following stillbirth. Knowledge of cognitive predictors and risk factors of PTSD may inform the development of a screening instrument.
