Classic and spatial shift-share analysis of state-level employment change in Brazil
This paper combines classic and spatial shift-share decompositions of 1981 to 2006 employment change across the 27 states of Brazil. The classic shift-share method shows higher employment growth rates for underdeveloped regions that are due to an advantageous industry-mix and also due to additional job creation, commonly referred to as the competitive effect. Alternative decompositions proposed in the literature do not change this broad conclusion. Further examination employing exploratory spatial data analysis (ESDA) shows spatial correlation of both the industry-mix and the competitive effects. Considering that until the 1960s economic activities were more concentrated in southern regions of Brazil than they are nowadays, these results support beta convergence theories but also find evidence of agglomeration effects. Additionally, a very simple spatial decomposition is proposed that accounts for the spatially-weighted growth of surrounding states. Favourable growth in northern and centre-western states is basically associated with those states’ strengths in potential spatial spillover effect and in spatial competitive effect
Word processing as an act of collaboration: description of a media artwork
As described in an earlier contribution to the JMP (Photography as an act of collaboration - Vol 15, Issue 3), my research explores the possibilities and implications of treating the camera and the photographic process as an active collaborator in the creation of scenes, events and ‘moments’ that did not exist until brought into being by the act of photographing them. The media artwork described here is the result of an experiment to explore the possibility of establishing a similarly collaborative relationship with the ‘agency’ of word-processing software that I have endeavoured to establish with the medium of photography. Despite comprehensively stripping the original text of both sense and sequence, the resulting text not only retains an uncanny degree of consistency with both the style and meaning of the original, but also reveals insights which had been only latent within the original. The result would appear to reinforce the findings of my previous research in photographic practice: that, by giving up conscious, rational control over the means of expression, we can (sometimes) create the conditions necessary for a constructive and often illuminating dialogue with the deus ex machina
Respuestas de oyentes y expertos musicales a una encuesta para valorar la percepción musical en salas de conciertos, auditorios y teatros
Para valorar la percepción musical en salas de concierto se diseñó una encuesta de 58 preguntas
en la que cada una se valoraba de 0 a 5 puntos. A esta encuesta han respondido 1057 personas
entre público en general y expertos musicales, sin formación especializada en acústica, tras la
audición de un concierto en alguno de los 14 auditorios, salas de conciertos y teatros ubicados en
diferentes comunidades de nuestro país (8 en el sur y 6 en levante). El análisis de las respuestas
obtenidas ha mostrado que la fluctuación de la valoración media de cada una de las preguntas de
la encuesta en una sala es un patrón que se repite aproximadamente en todas las salas
estudiadas, formando una banda de aproximadamente 1 punto de variación en cada respuesta que
contiene a todas las salas. Los límites de esta banda indicarían los extremos de respuesta
subjetiva asociada a las salas de conciertos.Ponencia presentada en el Encuentro Ibérico de Acústica. EAA Symposium. Gandía(España). 2006.In order to evaluate the quality of the musical perception in concert halls, a survey with 58 items
was designed in which each question was valued from 0 to 5 points. This survey has been replied
by 1057 people between general public and musical experts without any specialized formation in
acoustics, after the audition of a concert in any of the 14 auditoriums, concert hall or theatres,
located in different regions of our country (8 in the south and 6 in the east). The analysis has shown
that the fluctuation of the mean valuation of each question of the survey in a determined room is a
pattern that is repeated approximately in all of the studied spaces, forming a band of approximately
1 variation point in each answer and that contains to all rooms. The limits of this band would
indicate the ends of the subjective response associated to concert halls
Elaboration process of a subjective response test from listeners and Musical experts, as a tool of evaluation of the musical perception in Concerts halls, auditoria and theatres
In order to tackle the study related to the requirements for musical audition in concert halls, some
measurements and analyses of objective acoustic parameters have been made. However, the
subjective evaluation of the sensation that the values of these acoustic parameters have on the
listeners, can only be shown by means of a questionnaire that listeners have to answer. Such
questionnaire has been formulated in an understandable way and the questions are directly or
indirectly related to the abovementioned parameters. The aim of the present article is to present the
elaboration process of a test of subjective response addressed to the general public and to some
musical experts who have no special skills on acoustics. This study has been made in 13 auditoria,
concert rooms and theatres distributed in different Autonomous Regions of Spain.Para abordar el estudio de las exigencias para la audición musical en salas de conciertos se realiza
la medida y análisis de parámetros acústicos objetivos. Sin embargo, la valoración subjetiva de la
sensación que unos u otros valores de esos parámetros acústicos producen en la audiencia, sólo
puede ponerse de manifiesto a través de las respuestas de los oyentes a una encuesta cuyas
preguntas, formuladas de manera comprensible, estén relacionadas, directa o indirectamente, con
dichos parámetros acústicos. El objeto de este artículo es presentar el proceso de elaboración de
un test de respuesta subjetiva dirigido al público en general y a expertos musicales pero sin
formación especializada en acústica. Este estudio se ha realizado en 13 auditorios, salas de
conciertos y teatros repartidos en diferentes Comunidades Autónomas de nuestro país.

Evolution of clinical features in possible DLB depending on FP-CIT SPECT result
Objective: To test the hypothesis that core and suggestive features in possible dementia with Lewy bodies (DLB) would vary in their ability to predict an abnormal dopamine transporter scan and therefore a follow-up diagnosis of probable DLB. A further objective was to assess the evolution of core and suggestive features in patients with possible DLB over time depending on the 123I-FP-CIT SPECT scan result.
Methods: A total of 187 patients with possible DLB (dementia plus one core or one suggestive feature) were randomized to have dopamine transporter imaging or to follow-up without scan. DLB features were compared at baseline and at 6-month follow-up according to imaging results and follow-up diagnosis.
Results: For the whole cohort, the baseline frequency of parkinsonism was 30%, fluctuations 29%, visual hallucinations 24%, and REM sleep behavior disorder 17%. Clinician-rated presence of parkinsonism at baseline was significantly (p = 0.001) more frequent and Unified Parkinson’s Disease Rating Scale (UPDRS) score at baseline was significantly higher (p = 0.02) in patients with abnormal imaging. There was a significant increase in UPDRS score in the abnormal scan group over time (p < 0.01). There was relatively little evolution of the rest of the DLB features regardless of the imaging result.
Conclusions: In patients with possible DLB, apart from UPDRS score, there was no difference in the evolution of DLB clinical features over 6 months between cases with normal and abnormal imaging. Only parkinsonism and dopamine transporter imaging helped to differentiate DLB from non-DLB dementia
Conception participative et évaluation d'un serious game pour les enfants asthmatiques
International audienceThe study described in this paper highlighted the participatory design process (PD) in the context of asthma e-learning. First, we described global process to design this tool named KidBreath. Second, we evaluated in two Year 4 classes its efficacy in a motivation way, usability, disease knowledge and interests of children by their system. Results showed, in acceptance with behaviors, high level of intrinsic motivation when using KidBreath, usability and enjoyment of edutainment activities. This pilot study tends to confirm to continue with this approach with asthma kids at home.L'étude décrite dans cet article met en exergue l'intérêt d'une approche de conception participative (CP) dans le cadre d'un apprentissage en ligne sur l'asthme pour les enfants. Après avoir décrit l'ensemble de la démarche pour la conception de cet e-learning nommé KidBreath, nous évaluons dans 2 classes de CE2 son efficacité au niveau motivationnel, utilisabilité, connaissance sur la maladie et émergence de l'intérêt que les enfants y portent à travers la curiosité qui en émerge. Les résultats, probants aux comportements observés, montrent un haut niveau de motivation intrinsèque pour utiliser l'outil, un fort taux d'utilisabilité et une grande satisfaction des activités ludo-éducatives. Cette étude pilote nous confirme de continuer dans cette approche en testant le système notamment auprès des enfants asthmatiques sur du moyen terme

VALIRACUST, PARC ACOUSTIQUE POUR UNE RIVIÈRE
Within the framework of Acoustic Poetics and Acoustic Design, the project of the Acoustic Park "VALIRACUST" for the river Valira in Andorra provides an artistic and cultural place of recreation in the river area from Escaldes-Engordany and Andorra la Vella to Santa Coloma. In order to carry out this project, we intend to use differential sound sources ; textures of the river bed (Smooth surfaces, stones, gravel, etc.), surface textures (waterfalls of different heights, springs, water sculptures, resonances, etc.), textures of facilities (recreation areas, pavements, outdoor furniture, sound games and other elements with the participation of water and sound).Dans le cadre de la Poétique Acoustique et la Conception Acoustique, le projet du Parc Acoustique "VALIRACUST" pour la rivière Valira d'Andorra, est présenté comme l'espace ludique-artistique et cultural qui, configurant un grand parc acoustique-aquifer, on peut disposer à travers la rivière des d'Escaldes Engordany et Andorra la Vella jusqu'à Santa Coloma. Pour la réalisation de ce projet, nous avons l'intention d'utiliser des sources de sons différentiels ; textures du fond de la rivière (surfaces lisses, pierres, graviers,..), avec des textures de surface (chutes d'eau de différentes hauteurs, fontaines, sculptures avec l'eau, résonances,..), textures d'équipement (zones de récréation, étude des pavés, mobilier urbain, jeux sonors, et d'autres éléments avec la participation de l'eau et du son)
