Being European interregional strategy towards the CAN, traduced (among others) by the encouragement of Latin-America integration, this research wonders about the nature of the EU’s actions for satisfying this ambition, their degree of influence and their efficiency in this goal. The working hypothesis is that the EU’s interregional strategy, of stimulation of Latin American integration, has evolved. It has moved from an idealized vision of total integration for ACN (at every level) towards a complex and pragmatic approach. This approach is complex in that it advances in two ways. Politically the EU- ACN relations are region-to-region. Economically, they become into a region-to-country dialogue. The result of the Trade Agreement EU – ACN, witnesses of that. Taking into account these results and entirely adhering to the assertion “interregionalism, as practiced by the EU, has the purpose of building and consolidating regional orders, whereas the US regional activities rather have the purpose of preventing strong regional formations to grow” (Hetnne, 2007), we demonstrate that the European interregional behavior gets comparable to the US one. It has Americanized. This Americanization implicates a triangular relationship among EU, ACN and US. It affects not only the characteristics of Latin-American integration but also the European approach to its own initiatives of stimulation of this phenomenon. It has given place to a combination of interregional strategies that we have called “complex interregionalism”. This name has been given to this phenomenon because it combines two kinds of interregionalism (pure and hybrid one) simultaneously. This intervention is divided in two main parts and a conclusion. 1. The first part concerns the introduction of the concepts of pure and hybrid interregionalism. 2. The second part concerns, the European interregional strategy. It is presented and compared to the US’ towards ACN. By this contrasting exercise, a double and complex EU’s interregional behavior is verified. It is a region-to-region political dialogue and region-to-country economical one. The results of the negotiation of the Free Trade Agreement EU-ACN are used as the illustration of this statement. In fact, this treaty, at the beginning conceived to stimulate ACN regional integration, became a factor of erosion of the Andean unity. It permits to identify an Americanization de facto of the European interregional strategy. 3. Conclusions. This conclusion part is sub-divided in two. First, we present the conclusions about the complex interregionalism of EU towards ACN. Second, we open a discussion about the deep reasons of the European interregional behavior. The objectives of the two European approaches to the ACN strategy of integration. Has it been imposed by the international needs? by the necessity of building other regions as valuable interlocutors? or by the commitment to development ? [less ▲]

ABSTRACT: BACKGROUND: The diagnostic ability of computer-based methods for cardiovascular system (CVS) monitoring offers significant clinical potential. This research tests the clinical applicability of a newly improved computer-based method for the proof of concept case of tracking changes in important hemodynamic indices due to the influence acute pulmonary embolism (APE). METHODS: Hemodynamic measurements from a porcine model of APE were used to validate the method. Of these measurements, only those that are clinically available or inferable were used in to identify pig-specific computer models of the CVS, including the aortic and pulmonary artery pressure, stroke volume, heart rate, global end diastolic volume, and mitral and tricuspid valve closure times. Changes in the computer-derived parameters were analyzed and compared with experimental metrics and clinical indices to assess the clinical applicability of the technique and its ability to track the disease state. RESULTS: The subject-specific computer models accurately captured the increase in pulmonary resistance (Rpul), the main cardiovascular consequence of APE, in all five pigs trials, which related well (R2 = 0.81) with the experimentally derived pulmonary vascular resistance. An increase in right ventricular contractility was identified, as expected, consistent with known reflex responses to APE. Furthermore, the modeled right ventricular expansion index (the ratio of right to left ventricular end diastolic volumes) closely followed the trends seen in the measured data (R2 = 0.92) used for validation, with sharp increases seen in the metric for the two pigs in a near-death state. These results show that the pig-specific models are capable of tracking disease-dependent changes in pulmonary resistance (afterload), right ventricular contractility (inotropy), and ventricular loading (preload) during induced APE. Continuous, accurate estimation of these fundamental metrics of cardiovascular status can help to assist clinicians with diagnosis, monitoring, and therapy-based decisions in an intensive care environment. Furthermore, because the method only uses measurements already available in the ICU, it can be implemented with no added risk to the patient and little extra cost. CONCLUSIONS: This computer-based monitoring method shows potential for real-time, continuous diagnosis and monitoring of acute CVS dysfunction in critically ill patients. [less ▲]

Because of its many uses, the constrained optimization problem is presented in most calculus courses for mathematicians but also for economists. Looking at Lagrange's Theorem we are interested in studying the teaching of this theorem in both branches of study, mathematics and economics. This paper faces a twofold objective: first, we show the methodology of our research project concerning the didactic transposition of Lagrange's Theorem in university mathematics courses. Secondly, we would like to compare two mathematics courses given at the universities of Namur and Louvain by means of the "Anthropological Theory of Didactics" of Yves Chevallard. [less ▲]

The purpose of our study was the objective evaluation of micro-multileaf collimator (mMLC)-based stereotactic radiosurgery treatment plans. Forty-seven patients, 71 lesions received static beam conformal stereotactic radiosurgery treatment in our institute between November 2005 and June 2008. Target volume and organs at risk were outlined on a MRI-CT image fusion basis. BrainSCAN 5.31 system (BrainLAB AG, Heimstetten, Germany) was used for treatment planning, Elekta Presice TS linear accelerator (Elekta Oncology Systems Ltd, Crawley, UK) and BrainLAB m3 mMLC were used for treatment delivery. An invasive head frame, mounted to the treatment table, was used with four screws for patient head fixation. Treatment plans were analysed with objective parameters, such as conformal index (COIN), homogeneity index (HI), coverage index (CI) and healthy tissue relative overdose factor (HTOF) tools. x2 tests were performed between COIN, HI and the geometrical parameters of the target volume (lesion volume - LV, lesion-organ distance - LOD, lesion deformity index - LDI). Mean value of COIN, HI, HTOF and CI was 0.52 (SD 0.13), 1.16 (SD 0.1), 0.88 (SD 0.53), and 0.94 (SD 0.11), respectively. COIN significantly correlated with (p<0.001 in all three cases), while HI was independent of LV, LOD, LDI (p=0.94; 0.14 and 0.72). COIN is similar, HTOF is less than data from the literature. According to our results geometrical parameters of the target volume (size, location, deformation) significantly influence the COIN, but they have no effect on HI. [less ▲]

Light elicits robust nonvisual effects on numerous physiological and behavioral variables, such as the human sleep-wake cycle and cognitive performance. Light effects crucially rely on properties such as dose, duration, timing, and wavelength. Recently, the use of methods such as fMRI to assess light effects on nonvisual brain responses has revealed how light can optimize brain function during specific cognitive tasks, especially in tasks of sustained attention. In this chapter, we address two main issues: how light impinges on cognition via consolidation of human sleep-wake cycles; and how light directly impacts on sleep and cognition, in particular in tasks of sustained attention. A thorough understanding of how light affects sleep and cognitive performance may help to improve light settings at home and at the workplace in order to improve well-being. [less ▲]

BACKGROUND: Light exposure can cascade numerous effects on the human circadian process via the non-imaging forming system, whose spectral relevance is highest in the short-wavelength range. Here we investigated if commercially available compact fluorescent lamps with different colour temperatures can impact on alertness and cognitive performance. METHODS: Sixteen healthy young men were studied in a balanced cross-over design with light exposure of 3 different light settings (compact fluorescent lamps with light of 40 lux at 6500K and at 2500K and incandescent lamps of 40 lux at 3000K) during 2 h in the evening. RESULTS: Exposure to light at 6500K induced greater melatonin suppression, together with enhanced subjective alertness, well-being and visual comfort. With respect to cognitive performance, light at 6500K led to significantly faster reaction times in tasks associated with sustained attention (Psychomotor Vigilance and GO/NOGO Task), but not in tasks associated with executive function (Paced Visual Serial Addition Task). This cognitive improvement was strongly related with attenuated salivary melatonin levels, particularly for the light condition at 6500K. CONCLUSIONS: Our findings suggest that the sensitivity of the human alerting and cognitive response to polychromatic light at levels as low as 40 lux, is blue-shifted relative to the three-cone visual photopic system. Thus, the selection of commercially available compact fluorescent lights with different colour temperatures significantly impacts on circadian physiology and cognitive performance at home and in the workplace.

Dreaming pertains to both REM and NREM sleep. However, frequency and regional specific differences in EEG activity remains controversial. We investigated NREM and REM sleep EEG power density associated with and without dream recall in 17 young subjects during a 40-h multiple nap protocol under constant routine conditions. NREM sleep was associated with lower EEG power density for dream recall in the delta range, particularly in frontal derivations, and in the spindle range in centro-parietal derivations. REM sleep was associated with low frontal alpha activity and with high alpha and beta activity in occipital derivations. Our data indicate that specific EEG frequency- and topography changes underlie differences between dream recall and no recall after both NREM and REM sleep awakening. This dual NREM-REM sleep modulation holds strong implications for the mechanistic understanding of this complex ongoing cognitive process. [less ▲]

The Azorean flora, in contrast to that of other archipelagos, is characterized by a paucity of evolutionary radiations and the widespread distribution of most endemics. Several hypotheses, including isolation from the continent, recent age, ecological homogeneity, and limited paleoclimatic variations, have been proposed to account for this pattern. These hypotheses are tested here within the context of the molecular phylogeography of the heather Erica scoparia s.l., a Mediterraneo-Atlantic species complex distributed across Macaronesia, North Africa and southwestern Europe. The marked molecular radiation of this species in the Azores, including an array of single-island endemics, suggests that the apparent homogeneity of the Azorean flora might, in fact, conceal undetected patterns of endemism that are similar to those observed in the Canarian flora for morphological data. Haplotype richness was higher in the Azores than in the Canaries and extensive dispersal mediated allopatry is apparent at the molecular level. The Azores were colonized at least twice independently by E. scoparia, whereas the Canarian haplotypes are monophyletic, suggesting that the greater distance between the Azores and the continent does not necessarily hamper the chances of successful colonization.

Since the beginning of research on the éperon barré of Pont-de-Bonne (Modave, Belgium), we have recovered artefacts attributed to the Middle Neolithic. More recently, during excavation of the entrance system of the fortification, a pot hole and a waste accumulation zone have been analysed. These structures contained abundant archaeological material (ceramic sherd, lithic and bone artefact and fauna). Three radiometric dates have been obtained. The ceramic assemblage is typical of the Belgian Michelsberg and a decorated vase shows Bischheim affinities. [less ▲]

BACKGROUND: Motivation has long been emphasized as the most important determinant of action. However, there is a substantial gap between people's goals and their attainment. Patients may be motivated and yet unable to take action if their volitional competencies are insufficient. One of the important tasks of volition is goal-maintenance. Research has stressed the importance of a volitional tool, the implementation intentions. Implementation intentions indicate where, when, and how the action leading to the goal will be performed. Forming implementation intentions favours the execution of goal-directed efforts, and reinforces the relationship between intentions and behaviours. Results from various studies clearly suggest that volitional competencies and implementation intentions could play a role in low back pain (LBP) patients. However, there is at present no questionnaire allowing assessing the capacity of implementation intentions of physical activities in LBP patients. METHODS/DESIGN: This study will develop such a questionnaire, using a 3-step approach. A first qualitative step to build categories and generate items; 30 patients suffering chronic LBP will be invited to participate in semi-structured interviews; verbatim and derived items will then be submitted to a panel of experts, using a Delphi method; a second quantitative step to examine the properties of items, and determine the factorial structure of the questionnaire; 100 patients suffering chronic LBP will be recruited to respond to this phase; and third, preliminary psychometric analyses (item-scale correlations, construct validity, reliability); 180 chronic LBP patients will be recruited for this phase of the study. The relationships between implementation intentions and variables affecting physical activity on chronic LBP patients, i.e. pain, physical capacities, fear-avoidance beliefs, kinesiophobia, work status, and level of physical activity will be considered. DISCUSSION: Developing a questionnaire to assess implementation intentions would allow investigating the role of these intentions in the transition from acute to chronic LBP. The results of this study should contribute to the understanding of the psychological processes at stake in the development of chronic LBP, and in particular to the identification of factors eventually favouring patients' participation in and adherence to active physical treatments.
