Les cartes tactiles interactives pour améliorer l’accessibilité des données spatiales pour les déficients visuels

L'Organisation Mondiale de la Sante estime que 285 millions de personnes sont atteintes de deficiences visuelles dans le monde entier [11]. Cette population est confrontee a des defis importants lies a la perception des donnees spatiales. En effet, parce qu'elles sont avant tout visuelles, les representations spatiales ne sont pas facilement accessibles. Les personnes deficientes visuelles manquent alors d'exposition a des donnees geographiques, a des schemas mathematiques ou techniques, etc., avec des consequences importantes sur leur education mais aussi sur leur autonomie. Par exemple, 56% des personnes ayant une deficience visuelle en France ont declare avoir des problemes en matiere de mobilite et d'orientation sans avoir aucun probleme de motricite [6]. Il est certain que l'apprentissage a priori des environnements a parcourir permettrait de les rassurer et les encouragerait a se deplacer. Figure 1: Impression d'une carte tactile Historiquement, les deficients visuels utilisent des cartes en relief avec des legendes en braille pour acceder a des informations spatiales. Plusieurs etudes ont d'ailleurs demontre que les cartes tactiles permettent effectivement la creation de representations mentales de l'espace [10]. Differentes techniques et materiaux permettent la production de ces cartes tactiles. Il est par exemple possible de deformer du plastique pour lui donner du relief. Il est aussi possible d'utiliser une imprimante en Braille ou en relief, de l'encre feuilletee ou du papier gaufre [8]. La methode la plus souvent utilisee consiste a utiliser du papier thermoforme. Ce papier special contient des microcapsules d'alcool et peut passer dans une imprimante classique. Lorsque les feuilles imprimees sont passees dans un four, la chaleur fait gonfler les traces noirs (Figure 1). Neanmoins, ces cartes tactiles ont de nombreuses limitations. Tout d'abord, il est admis qu'il est tres difficile d'integrer des informations spatiales grâce a une exploration tactile. Il est donc necessaire de diminuer la quantite d'informations que les cartes tactiles peuvent afficher [9]. De plus, une fois imprimees, ces cartes ne sont plus modifiables et ne peuvent donc pas etre mises a jour. Finalement, l’ecriture en braille prend beaucoup de place. En general, seules les abreviations des figures sont placees sur la carte et sont accompagnees des legendes detaillees presentees sur une autre page, voire un petit fascicule. L’alternance entre la lecture de la carte et la lecture des legendes entraine des interruptions et augmente la charge cognitive necessaire a la comprehension. Il faut aussi noter que seule une petite partie des deficients visuels (15% en France) lit le braille [6]. Les non lecteurs sont alors prives des legendes et necessitent de l’aide pour comprendre ces cartes. Depuis quelques annees, il est evident que les progres technologiques permettent d’envisager la conception de cartes tactiles interactives bien plus accessibles.
Assemblage and Species Threshold Responses to Environmental and Disturbance Gradients Shape Bat Diversity in Disturbed Cave Landscapes

Ecological thresholds represent a critical tipping point along an environmental gradient that, once breached, can have irreversible consequences for species persistence and assemblage structure. Thresholds can also be used to identify species with the greatest sensitivity to environmental changes. Bats are keystone species yet are under pressure from human disturbances, specifically landscape and cave disturbances (i.e., reduced forest cover, urbanization, hunting, tourism). We compared bat assemblages across environmental and disturbance gradients measured at 56 caves in the Philippines to identify species-specific thresholds and assess congruence among species responses. All species exhibited significant responses to one or more gradients, with 84% responding to more than one gradient. Yet mixed responses of sensitivity to some gradients but tolerance to others hindered identification of assemblage thresholds to all gradients except landscape disturbance. However, we identified credible indicator species that exhibit distinct thresholds to specific gradients and tested for differences in ecological and morphological traits between species groups with shared responses (i.e., negative or positive). Few traits were useful for discriminating the direction of a species response, with some exceptions. Species that responded positively to increased landscape disturbance and hunting had greater body mass, whereas species that responded negatively to mining emitted higher peak call frequencies.
Morphological changes in ascospores of Saccharomyces cerevisiae during aerobic and anaerobic germination.

The stainability of ascospores and vegetative cells of Saccharomyces cerevisiae to acid-fast staining, using hot Ziehl's carbolic fuchsin solution, 5% sulfuric acid, and diluted Loffler's methylene blue, was examined. Resting spores and growing haploid cells (a type strain 24428 and α type 3626) retained much fuchsin dye in the cells. Only mature spores of diploid G2-2 resisted methylene blue staining. The stainability of Mycobacterium phlei IFO 3158 also examined.The kinetics of germinationn were examined. The loss of the stainability with acid-fuchsin and of the resistance to methylene blue was used as a criterion of germination. The ascospores germinated anaerobically as well as aerobically. Especially in the early stage of germination, there was found no difference in the germination rates under both conditions. Ultrastructure of germinating ascospores cultured in aerobic and anaerobic conditions was examined by ultrathin sectioning and electron microscopy. At the first stage of germination, the ascospores swelled in aerobic as well as anaerobic cultures. The outer spore coat and the outer zone of inner spore wall disappeared during the germination process, the inner zone of the spore wall then giving rise to a germinated spore cell wall (=extruded germ tube wall). The vacuole became granular. The mitochondria showed no change in shape and number in aerobic cultures, but seemed to swell and disintegrate in the later stages of anaerobic germination.
Antagonistic potentials of Trichoderma Spp. against fruit rot of custard apple caused by Phoma ligam

Context: Custard-apple ( Annona squamosa Linn.) is a popular tropical fruit and fruit-rot disease caused by Phoma lingam leads to considerable qualitative and quantitative damages to the fruit in the area under study. Objective: Studies were conducted to investigate the antagonistic potential of five Trichoderma spp. namely, T. harzianum, T. hamatum, T. lignorum, T. reesei and T. viride against in vitro growth of the pathogen followed by field experiments. Materials and Methods: Dual culture plate, closed petriplate and food poisoning technique were followed in order to ascertain the antagonistic potential of the five species of Trichoderma . Hyphal interaction between the pathogen and T. viride was studied by collecting mycelial samples from the interaction zone of dual culture plate and was processed for scanning electron microscope. Plants with infected fruits were sprayed with spore suspension of T. viride and two commercial bioformulations of T. viride viz. Trichofix and Trichoguard for three times at a dose of 0.1, 0.5 and 1.0% prepared in distilled water. Results : All the Trichoderma species more or less effectively inhibited the growth of the pathogen through mycoparasitism, production of volatile and non-volatile metabolites. Scanning electron microscopic (SEM) micrographs revealed that hyphal interaction between P. lingam and T. viride leads to lysis of the pathogenic mycelium by the antagonist. Field experiments with spore suspension of T. viride and Trichofix and Trichoguard significantly reduced fruit rot incidence of custard-apple. Conclusion : The results of the current study indicate that adoption of biocontrol based disease management programmes can be effectively utilized against similar fruit diseases.

Measuring Static Noise Margin of 65nm Node SRAMS using a 7-Positioner SEM Nanoprobing Technique

Non-visual fails have become an ever present complication in the IC industry. Nano probing SRAM bit cells at the inverter level allows the cell to be tested and static noise margin (SNM) to be measured. This paper explains how nano probing of a 65nm technology 6 transistor bit cell was performed and SNM dependence on supply voltage was measured for both hold and read modes. Connection to the bit cell was made at the Metal-1 layer with seven nano probes to collect the voltage transfer curves (VTCs) of the two inverters of the cell. In this experiment, each inverter was tested by varying Vdd voltage from 1.5, 1.2, 1.0, 0.8, 0.6, 0.4 and 0.2V while collecting the VTC. The two VTCs of the cell are plotted to produce the cell's butterfly curve from which the SNM is found graphically for each setting of Vdd.
Ricardo ’ s theory of value and taxation

The purpose of this paper is twofold: on the one hand is to discuss Ricardo’s version of the labour theory of value; and on the other hand, is to analyse some crucial aspects of Ricardo’s theory of taxation as an extension and further elaboration of his theory of value. This discussion is illustrated with the use of a formal model based on a generalisation of Ricardo’s numerical examples. The claim that the paper raises is that Ricardo’s analysis of taxation is a kind of a comparative statics exercise, where the real wage, the state of technology and the level of output are taken as givens. Furthermore, it is shown that Ricardo’s claim that money’s role in the presence of taxation of profits is not neutral becomes questionable, when various feedback effects are accounted for.
Evaluation of titanium dental implants after early failure of osseointegration by means of X-ray photoelectron spectoscopy, electron microscopy and histological studies

In this work, we analysed 56 clinically failed and retrieved implants by means of scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and histological studies. The surface contamination was compared to that of unused control implants and with that of the same implants after cleaning in a basic medium. The surfaces of the unused implants presented considerable contamination. In particular, high levels of carbon were detected. The nature of this C was elucidated by XPS analysis of the lubricant used in the machining process. The same contamination was observed in the retrieved implants. Histological studies were carried out by means of light microscopy. Fibrosis and granulomatous lesions were detected in the tissues. XPS analysis indicated the presence of traces of other elements (Na, Ca, Zn, S, F, etc.) that were not related to impurities in cpTi. We examined a cleaning process in a basic medium that eliminates the organic components of the implant surfaces. The cleaned implants were implanted in the patients and the results were excellent. None of the implants failed in following 7 months.
A data science game: assessing music recommendation with factorization machines

IN ENGLISH: Internet has seen a tremendous growth in the last few years. Because of that, we have a lot of information about most of the things in web. And the usage of Recommendation system has become more important than ever. Recommendation systems address this problem, by guiding users through the big ocean of information. Until now, recommendation systems have been extensively used within e-commerce and communities where items like movies, music and articles are recommended. More recently, recommendation systems have been deployed in online music players, recommending music that the users probably will like. This thesis will present the design, implementation, testing and evaluation of a recommendation system within the music domain, where three different approaches for producing recommendations are utilized. Testing each approach is done by evaluating the recommendation systems using precision scores. Our results show that the functionality of the recommendation system is satisfactory, and that recommendation precision differs for the three filtering approaches. ABSTRACT IN CATALAN:IN CATALAN: Internet ha experimentat un gran creixement en els últims anys. Per això, tenim molta informació sobre la majoria de les coses a la web. I l'ús del sistema de recomanacions s'ha tornat més important que mai. Els sistemes de recomanació tracten aquest problema, guiant els usuaris a través del gran oceà d'informació. Fins ara, els sistemes de recomanacions s'han utilitzat àmpliament en el comerç electrònic i comunitats on es recomana articles com ara pel·lícules, música i articles. Més recentment, els sistemes de recomanació s'han desplegat en reproductors de música en línia, recomanant música que probablement els usuaris agradin. Aquesta tesi presentarà el disseny, implementació, avaluació i avaluació d'un sistema de recomanacions dins del domini musical, on s'utilitzen tres criteris diferents per a la producció de recomenacions. La prova de cada enfocament es fa avaluant els sistemes de recomanació utilitzant puntuacions de precisió. Els nostres resultats mostren que la funcionalitat del sistema de recomanacions és satisfactòria i que la recomanació prediu els diàmetres dels tres enfocaments de filtració.

FROM ANTHESIS TO DIASPORE DISPERSAL: REPRODUCTIVE MECHANISMS OF RARE HERBACEOUS MORACEAE SPECIES ENDEMIC TO BRAZIL

Araújo, L. M. ; A. Valentin-Silva, G. W. Fernandes & M. F. Vieira. 2017. From anthesis to diaspore dispersal: reproductive mechanisms of rare herbaceous Moraceae species endemic to Brazil. Darwiniana, nueva serie 5(1): 83-92. FROM ANTHESIS TO DIASPORE DISPERSAL: REPRODUCTIVE MECHANISMS OF RARE HERBACEOUS MORACEAE SPECIES ENDEMIC TO BRAZIL 1Laboratório de Biologia Reprodutiva, Departamento de Biologia Vegetal, Universidade Federal de Viçosa, 36570-900 Viçosa, Minas Gerais, Brazil; adrianovalentin86@gmail.com (author for correspondence). 2Laboratório de Ecologia Evolutiva e Biodiversidade, Departamento de Biologia Geral, Instituto de Ciências Biológicas, Universidade Federal de Minas Gerais, 31270-901 Belo Horizonte, Minas Gerais, Brazil. Luzia Márcia de Araújo1, Adriano Valentin-Silva1, Geraldo W. Fernandes2 & Milene F. Vieira1 Studies on the reproductive biology of Dorstenia species are scarce. We analyzed the sexuality, floral biology, and diaspore dispersal of Dorstenia arifolia and D. bonijesu, including their breeding systems and pollinators, in natural populations from Minas Gerais state, southeastern Brazil. We report here, for the first time, the occurrence of both unisexual (male) and bisexual coenanthia on the same individuals of Dorstenia arifolia, while only bisexual coenanthia were observed in D. bonijesu. In both species all coenanthia were long-lived and bisexual coenanthia were protogynous. We observed the occurrence of self-compatibility and myophily in Dorstenia arifolia, a species which was pollinated by small Lauxaniidae flies. Those insects not only used pollen as food resource but they also used coenanthia as oviposition sites, which is the first report to the studied species. Dorstenia bonijesu produced seeds, even having no floral visitors, suggesting an apomictic mechanism, which is a new breeding system reported to the genus. Both studied species are autochorous, but D. bonijesu also exhibited a peculiar type of hydrochory. The novelties reported herein indicate the need of additional studies to improve the understanding of the reproductive attributes of Dorstenia species.
The Distributional Consequences of Tax Reforms Under Capital–Skill Complementarity

type="main" xml:id="ecca12087-abs-0001"> This paper analyses wage inequality and the welfare effects of changes in capital and labour income tax rates for different types of agents. To achieve this, we develop a model that allows for capital–skill complementarity given non-uniform distributions of asset holdings and labour skills. We find that capital tax reductions lead to the highest aggregate welfare gains but are skill-biased and thus increase inequality. However, our analysis also shows that the inequality effects of capital tax reductions are lower over the transition period compared with the long run.

THE INFLUENCE OF FIRMS STRUCTURAL CHARACTERISTICS ON THE DEGREE OF AGGLOMERATION ECONOMIES ENJOYED AMONGST FIRMS IN THE LAGOS REGION, NIGERIA

Agglomeration economies is a potent tool in socio-economic revamping, rejuvenation and sustenance of regions, this is as a result of the impulse it transmitted through the multiplier effect it is capable of generated. Therefore, this paper underscores the influence of firms structural characteristics on the degree of agglomeration economies enjoyed amongst firms, using the Lagos region as a case study. The first stage in the collection of primary data involves the reconnaissance survey, thereafter one hundred and three questionnaire were administered in twelve industrial estates; one questionnaire in each of the firm. The paper reveals the following structural characteristics as germane to industrial enterprise; age of firms, areal plant size (m2), capacity utilization (in percentage), and Labour size and firms investment. The paper has also found out those agglomeration economies enjoyed ranges from transportation, labour, power supply, to joint water supply. The Roy’s Largest Root test employed to test for the significance of the canonical correlations at 0.05 significant levels shows the calculated F-value 3.5247 and the tabulated F-value 2.90. This suggests that the degree of agglomeration economies enjoyed by firms is significantly explained by the size and structural characteristics of the firms. The paper therefore recommends more and active government participation in the industrial scene, given the necessary support for the expansion of firm’s structural characteristics which will lead to increase agglomeration economies enjoyed by these firms.
Synthesis, characterization and comparative studies of mono- and dimeric copper(II) complexes containing tripodal ligands

Mono and dimeric bromo-bridged copper(II) complexes of the type [CuBr2(L)] and [Cu2Br2(L)2](ClO4)2 containing nitrogen donor tripodal ligands L = 2,6-bis(pyrazol-1-yl)pyridine (bppy) or 2,6-bis(3,5-dimethylpyrazol-1-yl)pyridine (dmbppy) have been synthesized. All complexes have been characterized by elemental analysis, IR, ESR and electronic spectra and magnetic susceptibility and cyclic voltammetry measurements.
On the Integration of Emerging Stock Markets in the Middle East

Results from the Johansen-Juselius test suggest that the Middle East emerging stock markets are segmented globally, but appear highly integrated within the region. Moreover, the Gonzalo- Granger test, in conjunction with error-correction models, indicates that the market in Egypt is a dominant force driving other markets in the region. The apparent segmentation of the markets in the Middle East from the global market implies that these emerging markets provide international investors with potential diversification gains.
Recent Development on Entrepreneurial Leadership Capabilities and Innovativeness in Academic Libraries: A Review and Directions for Future Research

Entrepreneurial leadership offers an approach for library leader to be envisage, opportunistic, visionaries and influentials in facing the academic libraries transformation due to fiscal constraints and pressure to be distinctive. This paper aims to address issues related to the relationship between entrepreneurial leadership capabilities and academic library innovativeness by looking at the gaps from the previous studies. The Leader Member Exchange (LMX) theory of the leadership is use as the underpinning theory, as guidance and to support the conceptual framework and therefore focused on the dimensions of entrepreneurial leadership capabilities (strategic, communicative, personal and motivational) as factors that could explain innovativeness in academic libraries. This review is a first step for library managers to anticipate entrepreneurial leadership, to transform their organizations to meet the changing information and service needs of users, even while under fiscal constraints.
Outsourcing as Compassion? The Case of the Manufacture of Cigarettes By Poor Catholic Nuns (1817-1819)

(WP 09/03 Clave pdf) This study adopted a historical perspective to trace back outsourcing through examination of the case of cigarette manufacturing by poor Catholic nuns during 1817-1819, that is, from the launch of said product until the cessation of operations as a consequence of low demand. In the context of an absolutist regime, justification for the outsourcing decision drew on arguments of compassion. The decision was enacted in a decree signed by King Fernando VII and assigned monitoring of outsourcing to the Royal Tobacco Factory of Seville. We examined the divergence between public discourse and actual practice from the standpoint of the Foucauldian framework of power/knowledge.
Forty Sixth CIRP Conference on Manufacturing Systems 2013 Passive haptic feedback for manual assembly simulation

In this study movable props representing an object were used to try to achieve realistic movements of a worker during completion of a manipulation task in an assembly-like scenario recreated in a mixed reality environment. The form and the weight of the movable props were adjusted to different resemblance levels. The effect of these levels on the experiential fidelity of the worker and on the action fidelity of process observers was studied. Results showed that increasing the fidelity of the movable props does not necessarily result on better performance, e.g. simulating the weight of the actual object only seems to improve the experience if the prop also resembles the form of the actual object. Further study is suggested to better understand the effect of other factors.
