Comparing reading processes on e-ink displays and print

E-book reading devices open new possibilities in the field of reading. More activities than just reading a book can be performed with a single electronic device. For a long time, electronic reading devices have not been favored because their active LCD displays used to have a relatively low contrast. The new generation of electronic reading devices differs from earlier ones in the nature of the display: active LCD displays have been replaced with displays based on e-ink technology, which has display properties closer to that of printed paper. Moreover, e-ink technology has higher power efficiency, thereby increasing battery life and reducing weight. At first sight, the display looks similar to paper print, but the question remains whether the reading behavior also is equal to that of reading a printed book. In the present study, we analyzed and compared reading behavior on e-reader displays and on printed paper. The results suggest that the reading behavior on e-readers is indeed very similar to the reading behavior on print. Participants shared similar proportions of regressive saccades while reading on e-readers and print. Significant differences in fixation duration suggest that e-readers, in some situations, may even provide better legibility.

Connectivity patterns inferred from the genetic structure of white seabream (Diplodus sargus L.)

Themarine environment seems, at first sight, to be a homogeneousmediumlacking barriers to species dispersal. Nevertheless, populations of marine species show varying levels of gene flow and population differentiation, so barriers to gene flow can often be detected. Weaimto elucidate the role of oceanographical factors ingenerating connectivity among populations shaping the phylogeographical patterns in the marine realm, which is not only a topic of considerable interest for understanding the evolution ofmarine biodiversity but also formanagement and conservation of marine life. For this proposal,we investigate the genetic structure and connectivity between continental and insular populations ofwhite seabreamin North East Atlantic (NEA) and Mediterranean Sea (MS) aswell as the influence of historical and contemporary factors in this scenario using mitochondrial (cytochrome b) and nuclear (a set of 9 microsatellite) molecular markers. Azores population appeared genetically differentiated in a single cluster using Structure analysis. This result was corroborated by Principal Component Analysis (PCA) and Monmonier algorithm which suggested a boundary to gene flow, isolating this locality. Azorean population also shows the highest significant values of FST and genetic distances for both molecular markers (microsatellites and mtDNA). We suggest that the breakdown of effective genetic exchange between Azores and the others' samples could be explained simultaneously by hydrographic (deep water) and hydrodynamic (isolating current regimes) factors acting as barriers to the free dispersal of white seabream(adults and larvae) and by historical factors which could be favoured for the survival of Azorean white seabream population at the last glaciation. Mediterranean islands show similar genetic diversity to the neighbouring continental samples and nonsignificant genetic differences. Proximity to continental coasts and the current system could promote an optimal larval dispersion among Mediterranean islands (Mallorca and Castellamare) and coasts with high gene flow.

Ingestion rates of Artemia nauplii for different larval stages of Macrobrachium rosenbergii

The functional response between ingestion rate and food concentration was determined for each larval stage of Macrobrachium rosenbergii. Artemia franciscana nauplii were supplied at 2,4, 6, 8, 10 and 12 per milliliter. The nauplii were counted by sight using a Pasteur pipette and transferred to Petri dishes containing 40 ml of brackish water (12 parts per thousand) lying on the top of black plastic. One larva at each stage was individually placed into each Petri dish containing different food density. After 24 h, each larva was removed from the Petri dish and the leftover nauplii were counted. The amount consumed was determined by the difference between the initial and final number of nauplii. Ingestion rate (I) increased as food density (P) increased and was defined by the model I=I-m(1-e(-kP)). The results suggest four levels of ingestion during larval development. The first level includes stages II, III and IV, with average maximum consumption of about 40 nauplii/day; the second level includes stages V and VI, with consumption of approximately 55 nauplii/day; the third level includes stages VII and VIII, with consumption of 80-100 nauplii/day. The fourth level includes stages IX, X and XI, in which the high values for maximum ingestion (Im) exceed the load capacity of the medium. The low values for constant k (that may correspond to the adaptability of the food to prey characteristics, such as, size, mobility, etc.) obtained for stages IX, X and XI indicated that Artemia is not an adequate prey and there is necessity of a supplementary diet. The best relationship between predator and prey seemed to occur during stage IV Results obtained in the present work may subsidize future researches and serve as a guideline for practical considerations of feeding rates.

Ampliação de movimentos na dança circular com pessoas com deficiência visual

This paper aims at studying how circular dance can afford to sight-disabled peoples movement and how they can learn to cope with the deep movement of relation, consciousness, appropriation and communion with the world. Inside circular dance, a cosmic metaphor, is inscribed the movement of the world, which tells and changes amorously the human history. In the works of Paulo Freire and Maurice Merleau-Ponty one can find the necessary support to discuss, as long as possible, movement and existence. Research-action is used as a methodological approach whose empirical center is placed on the Institute of Education and Rehabilitation of Blind, in Natal, which shelters eight sightdisabled adults. The research s data reveal that the practice of circular dance concurs to enlarge the movement of the research s subjects, to develop a more accurate perception of their selves and of their own capacities, as well as improve the relations Me/Others, Me/World, which require a context of differences. The study has revealed that the practice of dance develops a better perception of the limits and surpasses as a human condition and, in consequence, the discovery of one s own body and the other s body as a resource of lessons and representations of the self and of the world. It lets out the development of a new way of thinking and coping with discrimination surrounding the disabled persons. In movement, in circular dance, the barrier between sight disablement and vision loses force.

Clinical characteristics and selection of treatment modality for patients with vitreomacular traction:real-world implementation of NICE guidance (TA297)

Aim: To investigate the qualitative aspects in patient selection and the quantitative impact of disease burden in real world treatment of vitreomacular traction (VMT) and implementation of the National Institute for Health and Care Excellence (NICE) guidance (TA297). Methods: A monocentric, retrospective review of consecutive patients undergoing optical coherence tomography (OCT) imaging over a 3 month period. Patients with VMT in at least one eye were identified for further data collection on laterality, visual acuity, symptoms, presence of epiretinal membrane, macular hole and treatment selection. Results: A total of 3472 patients underwent OCT imaging with a total of 6878 eyes scanned. Out of 87 patients, 74 patients had unilateral VMT (38 right, 36 left) and 13 patients had bilateral VMT. Eighteen patients with unilateral VMT satisfied NICE criteria of severe sight problems in the affected eye. Eight were managed for a coexisting pathology, one refused treatment, one patient did not attend, two closed spontaneously, and one received ocriplasmin prior to the study start date. Only two patients with unilateral VMT received ocriplasmin and three underwent vitrectomy. Those failing to meet NICE criteria for unilateral VMT were predominantly asymptomatic (n=49) or had coexisting ERM (n=5) or both (n=2). Conclusion: Ocriplasmin provides an alternative treatment for patients with symptomatic VMT. Our data shows that the majority of patients with VMT do not meet NICE TA297 primarily due to lack of symptoms. Those meeting NICE criteria, but not treated, tended to have coexisting macular pathology. Variation in patient selection due to subjective factors not outlined in NICE guidance suggests that real world outcomes of ocriplasmin therapy should be interpreted with caution.

Double blind test series

Braille is a communication tool in decline, in America by 80% since 1950, and in the UK to the extent that only 1% of blind people are now thought to read Braille.1, 2 There are a variety of causal factors, including the phasing out of Braille instruction due to the educational mainstreaming of blind children and the resistance to learning Braille by those who lose sight later in life.3Braille is a writing system of raised dots that allows blind people to read and write tactilely. Each Braille character comprises a cell of six potentially raised dots, two dots across and three dots down. It is designed only to communicate the message and does not convey the tonality provided by visual fonts.However, in his book Design Meets Disability, Graham Pullin, observes that: “Braille is interesting and beautiful, as abstract visual and tactile decoration, intriguing and indecipherable to the nonreader ” and continues; “…braille could be decorative for sighted people.”4I assert that the increasing abandonment of Braille frees it from its restrictive constraints, opening it to exploration and experimentation, and that this may result in Braille becoming dynamic expression for the sighted, as well as the partially sighted and blind.Printmaking is well suited for this exploration. Printmaking processes and techniques can result in prints aesthetically compelling to both senses of sight and touch. Established approaches, such as flocking, varnishes, puff-ink, embossing and die cut, combined with experiments in new techniques in laser cutting and 3D printing, create visually and texturally vibrant prints.In this paper I will detail my systematic investigation of sensually expressive printmaking concentrating on the issues surrounding Braille as a printmaking design element paying particular attention to the approaches and techniques used not only in producing its visual style but to those techniques used to keep it integrally tactile.

The paper describes the experimental genesis of a series of prints that examines how sight influences perception, designed to engage an audience of varying visual abilities.

Atmospheric calibration for sub-millimeter radio astronomy

This thesis is focused on improving the calibration accuracy of sub-millimeter astronomical observations. The wavelength range covered by observational radio astronomy has been extended to sub-millimeter and far infrared with the advancement of receiver technology in recent years. Sub-millimeter observations carried out with airborne and ground-based telescopes typically suffer from 10% to 90% attenuation of the astronomical source signals by the terrestrial atmosphere. The amount of attenuation can be derived from the measured brightness of the atmospheric emission. In order to do this, the knowledge of the atmospheric temperature and chemical composition, as well as the frequency-dependent optical depth at each place along the line of sight is required. The altitude-dependent air temperature and composition are estimated using a parametrized static atmospheric model, which is described in Chapter 2, because direct measurements are technically and financially infeasible. The frequency dependent optical depth of the atmosphere is computed with a radiative transfer model based on the theories of quantum mechanics and, in addition, some empirical formulae. The choice, application, and improvement of third party radiative transfer models are discussed in Chapter 3. The application of the calibration procedure, which is described in Chapter 4, to the astronomical data observed with the SubMillimeter Array Receiver for Two Frequencies (SMART), and the German REceiver for Astronomy at Terahertz Frequencies (GREAT), is presented in Chapters 5 and 6. The brightnesses of atmospheric emission were fitted consistently to the simultaneous multi-band observation data from GREAT at 1.2 ∼ 1.4 and 1.8 ∼ 1.9 THz with a single set of parameters of the static atmospheric model. On the other hand, the cause of the inconsistency between the model parameters fitted from the 490 and 810 GHz data of SMART is found to be the lack of calibration of the effective cold load temperature. Besides the correctness of atmospheric modeling, the stability of the receiver is also important to achieving optimal calibration accuracy. The stabilities of SMART and GREAT are analyzed with a special calibration procedure, namely the “load calibration". The effects of the drift and fluctuation of the receiver gain and noise temperature on calibration accuracy are discussed in Chapters 5 and 6. Alternative observing strategies are proposed to combat receiver instability. The methods and conclusions presented in this thesis are applicable to the atmospheric calibration of sub-millimeter astronomical observations up to at least 4.7 THz (the H channel frequency of GREAT) for observations carried out from ∼ 4 to 14 km altitude. The procedures for receiver gain calibration and stability test are applicable to other instruments using the same calibration approach as that for SMART and GREAT. The structure of the high performance, modular, and extensible calibration program used and further developed for this thesis work is presented in the Appendix C.

Love’s Calling How eroticism encourages religious intentions in "Joseph and Aseneth" and the "AEthiopika"

Ce mémoire s’intéresse à l’emploi de l’érotisme et de l’amour comme outils littéraires dans deux romans de l’Antiquité. Le texte principal est un écrit dérivé de la Torah intitulé Joseph et Aséneth. Le second est le roman grec d’Héliodore d’Émèse, Les Éthiopiques. Puisque tout auteur, peu importe sa foi, avait une éducation hellénique semblable, on retrouve des motifs similaires dont les détails se distinguent et les buts sont aux antipodes dans ces textes. Dans le cas de cette recherche, il s’agit de deux oeuvres du genre romanesque écrites en grec qui emploient chacune une histoire romantique à des fins édifiantes. Les buts de cette analyse sont triples. Ce travail cherche à montrer que Joseph et Aseneth a droit au titre de « roman grec, » de qualifier les expériences religieuses présentées dans ces oeuvres et de participer au débat sur la datation de Joseph et Aseneth par une étude comparée. Cette recherche se divise en trois sections. D’abord, le topos bien connu des romans a été analysé : la maladie d’amour. Dans les deux cas, le coup de foudre et la maladie émotionnelle qui s’en suit ont été dévoilés comme moteur important de la trame narrative, ainsi qu’une manière d’introduire des thèmes religieux ou philosophiques. En second lieu, les paroles des personnages au sujet de l’amour et le mariage ont été considérées. Puisque les protagonistes refusent le mariage initialement, les raisons données pour ce refus ont été révélatrices encore une fois de soucis sociaux, soit religieux, soit politiques. En dernier lieu, la relation entre le couple romantique et les dieux présents dans ces récits a été analysée. Les deux romans témoignent de la croyance contemporaine du grand rôle des dieux dans la vie des humains. Cette implication divine dans la vie mortelle s’est manifestée de manières différentes, car elle relève des buts divergents des deux romans. Le parallèle qui se présente est un lien individuel avec les dieux qui est évident dans les romans d’amour.

Mercadeo farmacéutico de productos bajo prescripción: efectos de las estrategias Direct-to-Consumer-Advertising en el comportamiento de los consumidores y de prescripción de los médicos

Este proyecto se origina en el interés de analizar las estrategias actuales de promoción de productos farmacéuticos, en el marco del debate sobre el efecto persuasivo o informativo que la publicidad directa tiene sobre los consumidores. El objetivo es determinar el efecto de las estrategias de promoción directa para consumidores (Direct to Consumer Advertising [DTCA]) sobre el comportamiento de compra de pacientes y las prescripciones que formulan los médicos en el mercado de productos bajo receta en Estados Unidos. Para tal fin se propuso realizar una monografía que incluyera una revisión de literatura de carácter argumentativo, consultando información de nivel secundario en bases de datos científicas cuyos contenidos obedecieran a criterios metodológicos determinados por la naturaleza argumentativa del estudio. Adicionalmente, se analizó el debate sobre estos anuncios a la luz de dos estudios realizados a pacientes con cáncer de seno, próstata y colon, liderados por el Pennsylvania Cancer Registry con los productos biofarmacéuticos Avodart® y Flomax®. Finalmente, la investigación se fundamentó en la relación del mercado farmacéutico en Estados Unidos con cada uno de los agentes que interactúan en él; consumidores, médicos prescriptores y empresas farmacéuticas, así como el valor que estos comparten través de dichas interacciones. Se concluye que el comportamiento de compra de los consumidores está determinado por la naturaleza de la patología que padecen y el comportamiento de los profesionales que prescriben a sus pacientes se ve influenciado por los anuncios DTCA.

A segunda vida da Praia dos Espanhóis: dançarinos, pescadores e turistas no sul de Portugal

Abstract: In this text, we deal with proccesses of appropriation of space in the Dam of Póvoa (Portugal) using a dwelling perspective (Ingold 2009) over the territory. The reconversion of innactive spaces in rural areas into leisure-related ones in a quite common practice in contemporary times.The Spaniards beach is one of the local names given by locals to the Dam of Póvoa (Castelo de Vide), in northern Alentejo (Portugal). In the collective memory of the residents, the Dam (built in the 1920’s) is remembered for the many flowers surrounding the area. This Garden-style aesthetics has outlived the initial function of the Dam (to produce electric power). From the 1960’s to the 1980’s, it was also a popular leisure space for Spanish and Portuguese people. It is not a beach, but being inland, it was the closest thing to a beach the residents had. The centrality of this leisure space in the area only decayed after the construction of swimming pools in the nearby towns. Early in the begginning of 21st century a fire destroyed part of the natural floral landscape of the dam. Abandoned for some years, the place has still been appropriated by leisured people in day-trips (for sight-seeing, pic-nics), fishing competitions, caravan soujorns, and, since 2013, in a music and dance festival named Andanças (www.andancas.net). The research that underlies this paper was carried out between 2013 and 2016 by a team of anthropologists. An ethnography of the Dam and its uses, and of the festival and its participants was carried out. In our working-paper we higlight the main research findings achieved.
