Accès à la thrombolyse lors d'AVC: rôle des secours préhospitaliers et des médecins de premier recours [Access to thrombolysis in stroke: place of the rescue system and of the primary care physician].

Thrombolysis is the most effective treatment improving the outcome of patients suffering from acute stroke. Moreover, its effectiveness increases when administrated as quick as possible after the onset of the first symptoms. Prehospital selection of patients and their immediate transfer to stroke center are the principal factors allowing the practice of thrombolysis within the authorized time frame. On the basis of regional Swiss French data, it seems that patients evaluated by emergency physician and their direct transfer in an acute stroke unit reduces delays and allows for a higher thrombolysis rate.

Study of the combined radial post-feeding dispersion of the blowflies Chrysomya megacephala (Fabricius) and C. albiceps (Wiedemann) (Diptera, Calliphoridae)

Blowflies use discrete and ephemeral substrates to feed their larvae. After they run out of food, the larvae begin to disperse in order to find adequate places for pupation or additional food sources, a process named post-feeding larval dispersion. Some important aspects of this process were studied in a circular arena allowing the combined radial post-feeding dispersion from the center of the arena of C. albiceps and C. megacephala larvae. To determine the location of each pupa, the arena was divided in 72 identical sections starting from the center. The distance from the center, the depth and weight of each pupa were evaluated. Statistical tests were done to verify the relation between weight, depth and distance for pupation. From the total an average of 976 larvae released (488 for each species) were collected considering both experiments 456 C. megacephala pupae and 488 of C. albiceps. This demonstrates that C. albiceps probably preyed on 32 C. megacephala larvae during post-feeding dispersion. The study of this dispersion process can be used to estimate the postmortem interval (PMI) of human cadavers in legal medicine.

Microsatellites reveal high population viscosity and limited dispersal in the ant Formica paralugubris

We used microsatellites to study the fine-scale genetic structure of a highly polygynous and largely uni-colonial population of the ant Formica paralugubris. Genetic data indicate that long-distance gene flow between established nests is limited and new queens are primarily recruited from within their natal nest. Most matings occur between nestmates and are random at this level. In the center of the study area, budding and permanent connections between nests result in strong population viscosity, with close nests being more similar generically than distant nests. In contrast, nests located outside of this supercolony show no isolation by distance, suggesting that they have been initiated by queens that participated in mating flights rather than by budding from nearby nests in our sample population. Recruitment of nestmates as new reproductive individuals and population viscosity in the supercolony increase genetic differentiation between nests. This in turn inflates relatedness estimates among worker nestmates (r = 0.17) above what is due to close pedigree links. Local spatial genetic differentiation may favor the maintenance of altruism when workers raise queens that will disperse on foot and compete with less related queens from neighboring nests or disperse on the wing and compete with unrelated queens.

A pseudo-spectral method for the simulation of poro-elastic seismic wave propagation in 2D polar coordinates using domain decomposition

We present a novel numerical approach for the comprehensive, flexible, and accurate simulation of poro-elastic wave propagation in 2D polar coordinates. An important application of this method and its extensions will be the modeling of complex seismic wave phenomena in fluid-filled boreholes, which represents a major, and as of yet largely unresolved, computational problem in exploration geophysics. In view of this, we consider a numerical mesh, which can be arbitrarily heterogeneous, consisting of two or more concentric rings representing the fluid in the center and the surrounding porous medium. The spatial discretization is based on a Chebyshev expansion in the radial direction and a Fourier expansion in the azimuthal direction and a Runge-Kutta integration scheme for the time evolution. A domain decomposition method is used to match the fluid-solid boundary conditions based on the method of characteristics. This multi-domain approach allows for significant reductions of the number of grid points in the azimuthal direction for the inner grid domain and thus for corresponding increases of the time step and enhancements of computational efficiency. The viability and accuracy of the proposed method has been rigorously tested and verified through comparisons with analytical solutions as well as with the results obtained with a corresponding, previously published, and independently bench-marked solution for 2D Cartesian coordinates. Finally, the proposed numerical solution also satisfies the reciprocity theorem, which indicates that the inherent singularity associated with the origin of the polar coordinate system is adequately handled.

The benefits of limited feedback in organizations

In most firms, managers periodically assess workers' performance. Evidence suggeststhat managers withhold information during these reviews, and some observersargue that this necessarily reduces surplus. This paper assesses the validity of thisargument when workers have career concerns. Disclosure has two effects: it exposesthe worker to uncertainty about future effort levels, but allows him to use current effortto influence his employer's beliefs about future effort. The surplus-maximizingdisclosure policy reveals output realizations in the center of the distribution, butnot in the tails. Thus, it is efficient for firms to reveal some but not all performanceinformation.

The left-right dimension in Latin America

We present voters' self-placement and 68 political party locations on the left-right dimension in 17 Latin American countries. Innovative calculations are based on data from Latinobarometer annual surveys from 1995 to 2002. Our preliminary analysis of the results suggests that most Latin American voters are relatively highly ideological and rather consistently located on the left-right dimension, but they have very high levels of political alienation regarding the party system. Both voters' self-placement and the corresponding party locations are presently highly polarized between the center and the right, with a significant weakness of leftist or broadly appealing 'populist' positions.

Pupillographic investigation of the relative afferent pupillary defect associated with a midbrain lesion.

OBJECTIVE: To identify clinical and pupillographic features of patients with a relative afferent pupillary defect (RAPD) without visual acuity or visual field loss caused by a lesion in the dorsal midbrain. DESIGN: Experimental study. PARTICIPANTS AND CONTROLS: Four patients with a dorsal midbrain lesion who had normal visual fields and a clinically detectable RAPD. METHODS: The pupil response from full-field and hemifield light stimulation over a range of light intensities was measured by computerized binocular pupillography. MAIN OUTCOME MEASURES: The mean of the direct and consensual pupil response to full-field and hemifield light stimulation was plotted as a function of stimulus light intensity. RESULTS: All 4 subjects showed decreased pupillographic responses at all intensities to full-field light stimulation in the eye with the clinical RAPD. The pupillographic responses to hemifield stimulation showed a homonymous pattern of deficit on the side ipsilateral to the RAPD, similar to that observed in a previously reported patient with an optic tract lesion. CONCLUSIONS: The basis of a midbrain RAPD is the nasal-temporal asymmetry of pupillomotor input that becomes manifest when a unilateral postchiasmal lesion interrupts homonymously paired fibers traveling in the contralateral optic tract or midbrain pathway to the pupillomotor center, respectively. The pupillographic characteristics of an RAPD resulting from a dorsal midbrain lesion thus resemble those of an RAPD resulting from a unilateral optic tract lesion, but without the homonymous visual field defect.

Iowa Commission on the Status of African Americans Annual Report, Fiscal Year 2006

A Public Intellectual recently suggested that I read the book Life Out Of Context by the very productive writer Walter Mosley. In this book, Mosley began to summarize a speech that was given by Harry Belafonte. Belafonte made a comparison between a particular Olympic relay race and the Civil Rights Movement. In the race, an experienced runner stumbled a little while passing the baton, and the race was lost. For Belafonte, this momentary slip was a metaphor for the failure of the Civil Rights Movement to “pass the baton” to the younger generation as “it moved past its original phase and into the latter part of the century.” Regardless of your views of the strengths and weaknesses of the Civil Rights Movement, I think all of us would agree that the current issues facing Black Iowa today--e.g., the need for economic development, increased educational achievement and more political involvement in our communities--demand our immediate attention and action. This urgency requires that we cross generational, class, and territorial boundaries within the state to collaborate among ourselves and with others to deal constructively with these issues. We cannot afford to have another “momentary slip.” Serving as the Administrator for ICSAA allows me to serve Black Iowa in a significant way, and Kimberly Cheeks and I in this Division look forward to the work ahead over the next several months and years. Working closely with Walter Reed, Director of the Department of Human Rights, along with so many others across this state, we are keenly aware that we are provided with a great opportunity to positively impact the quality of life for African-Americans in Iowa.

Corporations do not exist in a vacuum, they are embedded in a socio-political context. This context shapes our ideas about what managers within corporations and corporations within society do or should do. The rise of a global world order at the threshold of the 21st century is transforming our society at high speed. Questions of business integrity and sustainability move center stage. This book, written on the occasion of the HEC Lausanne centennial by some thirty professors, discusses various aspects of responsible management practices for the 21st century and provides some key insights for managers today and tomorrow.

Anomalous Proper-Motions in the Cygnus Super Bubble Region

In an analysis of proper motions of O and B stars contained the Input Catalogue for Hipparcos, we have found a clear deviation from the expected pattern of systematic motions which can be readily identified with the associations Cygnus OB1 and Cygnus OB9, located near de the edge of the Cygnus Superbubble. Teha anomalous motions are directed outwards from the center of the Superbubble, which is coincident with tha association Cygnus OB2. This seems to support the hypothesis of a strong stellar and supernova activity in Cygnus 0B2 giving rise to the Superbubble and, by means of gravitational instabilities in its boundaries, to Cygnus 0B1 and Cygnus OB9. New uvby-beta aperture photometry of selected O and B stars in the area of Cygnus OB1 and Cygnus OB9 is also presented and analyzed in this paper.

Pentateuque, Hexateuque et historiographie deutéronomiste. Le problème du début et de la fin du livre de Josué

The book of Joshua is in the very center of the recent discussion about the existence of a coherent deuteronomistic redaction in Deut to 2 Kings during the exilic period. This article analyses the beginning (Josh 1.1-9) and the end (Josh 23 and 24) of Josh. Josh 1.1-2,5-7 and chapter 23 belong to the dtr edition. Josh 23 was followed by Judg 2.6ff. During the Persian period, Deuteronomists and priests intended to publish one Law for the whole community. There was probably a discussion whether the Torah should be a Penta- or a Hexateuch. This discussion may explain such a text as Josh 24 which clearly tries to construct an Hexateuch (cf. also Gen. 50.25: Exod 13.19; Josh 24.32). But since the Torah is about foundations, the main theological trends agreed to have its end with the death of Moses.

Some information concerning the State Historical Society of Iowa,1910.

In recent years historical research seems to be the State Historical Society's main function, although it was formed with the principal functions of collection, preservation and exhibition. Now, instead of simply attempting to make the largest possible collection of historical materials in one place, this society will now endeavor to compile, publish and distribute accurate and scientific historical literature. The book also lists publications, information on the library and on membership.

Measurements of the bulk and interfacial velocity profiles in oscillating Newtonian and Maxwellian fluids

We present the dynamic velocity profiles of a Newtonian fluid (glycerol) and a viscoelastic Maxwell fluid (CPyCl-NaSal in water) driven by an oscillating pressure gradient in a vertical cylindrical pipe. The frequency range explored has been chosen to include the first three resonance peaks of the dynamic permeability of the viscoelastic-fluid¿pipe system. Three different optical measurement techniques have been employed. Laser Doppler anemometry has been used to measure the magnitude of the velocity at the center of the liquid column. Particle image velocimetry and optical deflectometry are used to determine the velocity profiles at the bulk of the liquid column and at the liquid-air interface respectively. The velocity measurements in the bulk are in good agreement with the theoretical predictions of a linear theory. The results, however, show dramatic differences in the dynamic behavior of Newtonian and viscoelastic fluids, and demonstrate the importance of resonance phenomena in viscoelastic fluid flows, biofluids in particular, in confined geometries.
