Affective dependency is characterized by emotional distress (insecure attachment) and dependency to another person with a low self-esteem and reassurance need. The paper proposes a reflection on the definition of emotional dependency and the confusion caused by various denominations. Overprotective and authoritarian parenting, cultural and socio-environmental factors may contribute to the development of dependent personality. Psychological epigenetic factors, such as early socio-emotional trauma could <imprint>> on neuronal circuits in prefronto-limbic regions that are essential for emotional behaviour.We also focus on the interrelations between dependent personality, domestic violence and addictions. The objective for the clinician is to propose a restoration of self-esteem and therapeutic strategies focused on autonomy. [less ▲]

En dépit de controverses récurrentes, les données expérimentales récoltées dans de nombreuses études animales et humaines indiquent que le cannabis présente toutes les caractéristiques associées aux autres drogues toxicomanogènes. Le cannabis induit manifestement une dépendance psychologique primaire chez l’homme et les modèles animaux ont démontré qu’il possède des propriétés renforçantes, quoique de moindre intensité que celles d’autres drogues comme la cocaïne ou les opiacés. La consommation chronique de cannabis produit une tolérance envers certains de ses effets, ce qui est susceptible d’entraîner un accroissement des doses utilisées par un utilisateur régulier. On reconnaît aussi au cannabis la capacité d’induire une véritable dépendance physiologique chez les plus gros consommateurs. Cette dépendance physiologique se manifeste par un syndrome de sevrage typique lors de l’arrêt de la consommation. Toutefois, il est clair que la dépendance au cannabis (aussi bien psychologique que physiologique) est moins sévère que celle induite par d’autres drogues majeures comme l’alcool, la cocaïne ou les opiacés. De plus, elle ne concerne qu’une petite fraction des consommateurs de cannabis. Depuis de nombreuses années, on s’interroge sur le risque d’escalade vers la consommation de drogues « plus dures » que produirait la consommation de cannabis. Les études scientifiques ont clairement démontré qu’il existe un lien statistique significatif entre usage de cannabis et consommation d’autres drogues illicites. Toutefois, la nature de cette relation statistique reste controversée. Selon les tenants de « la théorie de la porte d’entrée », le cannabis conduit directement, par des mécanismes biologiques, psychologiques ou sociaux, à une augmentation du risque de consommer des drogues telles que la cocaïne ou l’héroïne. Au contraire, les adeptes de « la théorie du facteur commun » soutiennent que les consommations de cannabis, d’héroïne ou de cocaïne sont expliqués par des facteurs généraux identiques, conduisant ainsi à une relation statistique qui ne serait qu’apparente et en aucun cas de nature causale. A l’heure actuelle, les données expérimentales disponibles ne permettent pas de trancher définitivement entre ces deux théories explicatives. [less ▲]

Zolpidem is an imidazopiridine with hypnotic properties. Compared to benzodiazepines, zolpidem has a mechanism of action that is thought to reduce the risk of dependence or abuse. However, in the past 10 years, several cases of zolpidem abuse, dependence and withdrawal reactions have been described in the litterature. Here, we describe a case of dependence and withdrawal seizure. [less ▲]

Gravitational flows generated on a gentle slope in stable conditions were analysed at a forested site at Vielsalm in Belgium. There were two distinct situations at the site, one corresponding to vertical convergence, characterised by a negative vertical velocity at the canopy top and horizontal velocity divergence below the canopy, the other corresponding to an equilibrium situation without any vertical movement. The causes of these two distinct flow patterns were analysed. These measurements combined with those of the horizontal CO2 concentration gradient below the canopy supported the dilution hypothesis suggested by Aubinet et al. (2003): the horizontal CO2 concentration gradient is negative in convergence situations but slightly positive in equilibrium conditions. The existence of such patterns allows us to confirm the coherence of advection observations made at the site. However, the sum of turbulent CO2 flux, changes in CO2 storage and advective terms were shown to greatly overestimate the expected net ecosystem exchange in the convergence conditions. The most probable cause was identified as being a poor estimate of the vertical profile of the vertical velocity component. [less ▲]

The weight ratio of PE and PS in ternary PS/SBR/PE blends has been changed at constant SBR content (25 wt%). When the matrix is either PE or PS, the dispersed phase has a core-shell structure with SBR forming the shell. The size of the core expectedly increases with the content of the core-forming polymer. In some composition range, the three phases are simultaneously continuous, SBR being localized in between the co-continuous PE and PS phases. The ultimate mechanical properties of the ternary blends containing SBR/PE and SBR/PS core-shell dispersed phases are close to the properties of the PS/SBR and PE/SBR binary blends, respectively. Some synergism in the elongation at break of the ternary blends is observed when core-shell SBR/PS phases are dispersed in PE matrix. [less ▲]

PMMA containing 50 wt% of anthracene-labeled PMMA chains end-capped by a phthalic anhydride group (anth-PMMA-anh) has been melt blended at 180°C with PS containing 33 wt% of chains end-capped by an aliphatic primary amine (PS-NH2) and PS bearing 3.5 pendant amine groups (as an average) along the chains (PS-co-PSNBH2), respectively. The reactive chains have been synthesized by atom transfer radical polymerization. Conversion of anth-PMMA-anh into PS-b-PMMA and PS-g-PMMA copolymers has been monitored by SEC with a UV detector. The interfacial reaction mainly occurs in the initial melting and softening stage (<1.0 mm), although at a rate which strongly depends on the number of reactive groups attached to PS chains, the higher conversion being observed for the PS-co-PSNH2 containing blends. The phase morphology depends on the architecture of the in-situ formed copolymer Indeed, a coarser phase dispersion is observed in case of the graft copolymer compared to the diblock. [less ▲]

Poly(methyl methacrylate) (PMMA) containing 50 wt% of anthracene (anth) labeled reactive PMMA chains [thus end-capped by an anhydride (anh) or an isocyanate (NCO)] has been melt blended with polystyrene containing 33 wt% of chains end-capped by an aliphatic amine (PS-NH2) at 180degreesC. Conversion of anth-PMMA-anh and anth-PMMA-NCO into PMMA-b-PS copolymers has been determined by SEC with a UV detector. The interfacial reaction mainly occurs in the initial mixing stage (less than or equal to1.0 min), although at a rate which depends on the reactive groups attached to PMMA. Moreover, this interfacial reaction rate controls how the phase morphology is developed. [less ▲]

The poly(styrene)-block-poly(2-vinylpyridine)-block-poly(ethyleile oxide) triblock copolymer. PS200-b-P2VP(140)-b-PEO590, where the subscripts refer to the average degrees of polymerisation of the constitutive blocks, has been dissolved in water/toluene mixtures with a large range of composition, i.e. in (i) toluene added with a small amount of water. (ii) water-in-toluene emulsion forming mixtures, (iii) toluene-in-water emulsion forming mixtures, and (iv) water added with a small amount of toluene. These Solutions have been cast on a carbon-coated copper grid, and the morphology of the dried copolymer deposition has been observed by transmission electron microscopy. Rod-like aggregates with a core-shell-corona micellar structure are formed in cases (i) and (iv). Nevertheless, PEO is the core and PS is the corona in case (i). whereas the reverse situation prevails in case (iv). When an emulsion is the precursor of the dried copolymer aggregates, either onion-like structures (case ii) or vesicles mixed with more complex aggregates are formed (case iii). These structures are thought to reflect the self-organization of the PS200-b- P2VP(140)-b-PEO590 copolymer at the water/toluene interface of the water-in-toluene and toluene-in-water emulsions. respectively.

The aim of the present study was to identify and quantify the rate dependence of premature ventricular contractions (PVC) during childhood. A 24-hour Holter recording was performed in 16 consecutive children, aged 22 days to 11 years (mean age 5.6 years), with frequent (>5,000/day), isolated monomorphic PVC. Those PVC were identified and the length of the preceding sinus cycle was measured. The values were ordered into 50-ms class intervals, and the percentage of PVC for each class was calculated and then analyzed by linear regression analysis. On the basis of the significance of the p value, and the positive or negative value of the slope, we identified a tachycardia-enhanced, a bradycardia-enhanced, and an indifferent pattern. Chronobiologic analysis was made by the cosinor method. All the patients had upper and lower limits of cycle length beyond which PVC disappeared. A tachycardia-enhanced pattern was present in 7 patients and an indifferent one in 9 patients. In the latter a second-degree polynomial correlation was systematically found. Children but not infants had a significant circadian variation in the frequency of PVC with a very variable time of highest incidence. In conclusion, it is possible to identify a circadian rhythm of PVC and a spontaneous trend between their incidence and the length of the preceding cardiac cycle in children. [less ▲]

This paper scrutinizes various dependency-based representations of the syntax of function words, such as prepositions. The focus is on the underlying formal object used to encode the linguistic analyses and its relation to the corresponding linguistic theory. Two types of representation are proposed for the encoding of syntactic properties and applied for function words. Although the mathematical object introduced here encodes a dependency-based analysis, it does not consist in a tree. It is rather more general than a graph (it allows edges to be vertices of other edges) and is called a polygraph. [less ▲]

Analysis of meat expenditure by Belgian households in 2008. Meat expenditure by Belgian households during 2008 is analyzed. Expenditure is extracted from the Belgian Household Budget Survey at the FPS Economy, S.M.E.s, Self-employed and Energy. The database also provides sociodemographic information about the households participating in the survey. To explain the observed variability of the meat expenditure based on the explanatory factors available, an analysis of the covariance is performed. The three quantitative factors have a bigger effect on the meat expenditure than the three other qualitative factors. The proportion of meat expenditure variability explained by the explanatory factors of the selected model is 31,41%. [less ▲]
