  3. Hurricane Isabel gives accelerators a severe test

    2004-01-01

    Hurricane Isabel was at category five--the most violent on the Saffir-Simpson scale of hurricane strength--when it began threatening the central Atlantic seaboard of the US. Over the course of several days, precautions against the extreme weather conditions were taken across the Jefferson Lab site in south-east Virginia. On 18 September 2003, when Isabel struck North Carolina's Outer Banks and moved northward, directly across the region around the laboratory, the storm was still quite destructive, albeit considerably reduced in strength. The flood surge and trees felled by wind substantially damaged or even devastated buildings and homes, including many belonging to Jefferson Lab staff members. For the laboratory itself, Isabel delivered an unplanned and severe challenge in another form: a power outage that lasted nearly three-and-a-half days, and which severely tested the robustness of Jefferson Lab's two superconducting machines, the Continuous Electron Beam Accelerator Facility (CEBAF) and the superconducting radiofrequency ''driver'' accelerator of the laboratory's free-electron laser. Robustness matters greatly for science at a time when microwave superconducting linear accelerators (linacs) are not only being considered, but in some cases already being built for projects such as neutron sources, rare-isotope accelerators, innovative light sources and TeV-scale electron-positron linear colliders. Hurricane Isabel interrupted a several-week-long maintenance shutdown of CEBAF, which serves nuclear and particle physics and represents the world's pioneering large-scale implementation of superconducting radiofrequency (SRF) technology. The racetrack-shaped machine is actually a pair of 500-600 MeV SRF linacs interconnected by recirculation arc beamlines. CEBAF delivers simultaneous beams at up to 6 GeV to three experimental halls. An imminent upgrade will double the energy to 12 GeV and add an extra hall for ''quark confinement'' studies. On a smaller scale

    2017-04-01

    The Horizon 2020 funding project ISABEL (Triggering Sustainable Biogas Energy Communities through Social Innovation) is all about promoting, supporting and developing community biogas in Europe. The project is set on providing all the framework conditions for biogas communities to shape, develop and thrive. It works on all angles to pave the way for the transition from traditional supply chains to community ownership and take full advantage of the ample societal benefits of regional community-driven biogas systems, fuelled and inspired by Social Innovation principles. The biogas communities emerge in three targeted ISABEL regions, Baden-Württemberg in Germany, Central and Eastern Macedonia and Thrace in Greece and Yorkshire, Lincolnshire and the Humber in UK. To realize this vision ISABEL is employing its "5E strategy" with the following objectives: Educate: Re-position biogas energy by re-branding it as a "public good". Engage: Enable the development of regional Biogas Communities. Empower: Utilize the created momentum through Social Innovation and Public Participation Evaluate: Assess the local interventions and drafting lessons and guidelines Expand: Maximise impact through transfer and replication

  7. Simulating the formation of Hurricane Isabel (2003) with AIRS data

    2006-02-01

    Using the AIRS retrieved temperature and humidity profiles, the Saharan Air Layer (SAL) influence on the formation of Hurricane Isabel (2003) is simulated numerically with the MM5 model. The warmth and dryness of the SAL (the thermodynamic effect) is assimilated by use of the nudging technique, which enables the model thermodynamic state to be relaxed to the profiles of the AIRS retrieved data for the regions without cloud contamination. By incorporating the AIRS data, MM5 better simulates the large-scale flow patterns and the timing and location of the formation of Hurricane Isabel and its subsequent track. By comparing with an experiment without nudging of the AIRS data, it is shown that the SAL may have delayed the formation of Hurricane Isabel and inhibited the development of another tropical disturbance to the east. This case study confirms the argument by Dunion and Velden (2004) that the SAL can suppress Atlantic tropical cyclone activity by increasing the vertical wind shear, reducing the mean relative humidity, and stabilizing the environment at lower levels.

    Full Text Available The private archive of the Brazilian Imperial Family holds a wealth of little known documents about the education of the daughters of Emperor D. Pedro II, especially of the eldest, Isabel, Princess Imperial. Science, particularly chemistry, for which her father had a particular fondness, occupied an important place in the girl's education. The study of these documents sheds a new light on the contrast between female education in the country in general, during most of the 19th century, and the careful upbringing envisaged by the Emperor for his future successor.

  9. The utility of an online diagnostic decision support system (Isabel) in general practice: a process evaluation.

    2013-05-01

    To evaluate the utility of Isabel, an online diagnostic decision support system developed by Isabel Healthcare primarily for secondary medical care, in the general practice setting. Focus groups were conducted with clinicians to understand why and how they used the system. A modified online post-use survey asked practitioners about its impact on their decision-making. Normalization process theory (NPT) was used as a theoretical framework to determine whether the system could be incorporated into routine clinical practice. The system was introduced by NHS County Durham and Darlington in the UK in selected general practices as a three-month pilot. General practitioners and nurse practitioners who had access to Isabel as part of the Primary Care Trust's pilot. General practitioners' views, experiences and usage of the system. Seven general practices agreed to pilot Isabel. Two practices did not subsequently use it. The remaining five practices conducted searches on 16 patients. Post-use surveys (n = 10) indicated that Isabel had little impact on diagnostic decision-making. Focus group participants stated that, although the diagnoses produced by Isabel in general did not have an impact on their decision-making, they would find the tool useful if it were better tailored to the primary care setting. Our analysis concluded that normalization was not likely to occur in its current form. Isabel was of limited utility in this short pilot study and may need further modification for use in general practice.

  11. Recent recoveries of archaeological ceramics on Santa Isabel, central Solomon Islands

    Carter, M.J.; Roe, D.; Keopo, J.

    2012-01-01

    Recent field investigations on Santa Isabel in the Central Solomon Islands have revealed the presence of archaeological pottery in both terrestrial and intertidal contexts. Preliminary dating results and comparative stylistic analyses of sherds provide evidence to suggest an antiquity of ceramics in northwest Isabel spanning the late Holocene to the recent historic past. These research outcomes expand the known distribution of pottery within the Solomon Islands and provide new knowledge about the prehistory of Santa Isabel. Here we describe the Santa Isabel ceramics, and suggest several implications of the research for current settlement models of the Solomon Islands and for our understanding of the variability in the archaeological record of mid- to late-Holocene ceramic distribution throughout the region.

    Full Text Available Entre los documentos referentes al funcionamiento de la corte de la reina Isabel de Valois es posible encontrar datos fundamentales para conocer el quehacer de los profesionales médico-sanitarios en el siglo XVI, en este caso circunscritos al ámbito regio. La necesidad de velar por la salud de la Corte resultaba tan relevante como cualquier otro asunto digno de la atención del alto funcionariado encargado de la correcta marcha de los asuntos de Estado. Por este motivo, la gestión y administración de los recursos sanitarios del círculo cortesano generaron una interesante documentación, conservada en la sección Casa y Sitios Reales del Archivo General de Simancas, de la que en este artículo se analiza una significativa muestra.Among the documents concerning the functioning of Queen Isabel de Valois ‘court, it is possible to find fundamental information to know something about the duty of sanitary professionals in the sixteenth century, in this case circumscribe to the royal environment.

  13. Un retrato desconocido de Isabel la Católica

    Flor, Pedro

    2013-03-01

    Full Text Available The reserves of the National Gallery, London, house a painting identified as Mary Magdalene, by an unknown master most likely of Franco-Flemish origin. The iconographical identification of the subject derives from the small jar that she holds. A more thorough study of the piece, however, leads us to raise the hypothesis that it is actually a portrait of Isabella the Catholic, based on comparisons with other representations of this queen, as well as on the jewellery she wears. In spite of the stylistic comparisons made with contemporary works, it is difficult to establish the artist with precision. Nevertheless, we propose Michel Sittow –or someone from his artistic circle– whose activity at the service of the Spanish crown is documented precisely towards the end of the 15th and beginning of the 16th century.Las reservas de la National Gallery de Londres albergan una pintura identificada como María Magdalena atribuida a un maestro desconocido de posible origen franco-flamenco. La identificación iconográfica del personaje se basa en el pequeño frasco que sujeta. Sin embargo, un análisis más detallado de la obra nos permite plantear la hipótesis de que se trate antes de un retrato de Isabel la Católica, no sólo por comparación con otros ejemplares iconográficos de la Reina, sino también por las joyas que ostenta. Partiendo de la comparación estilística con obras coevas resulta problemático determinar con precisión el autor de la pintura, pero es posible que se trate de Michel Sittow o alguien de su círculo de influencia, cuya actividad se conoce precisamente a finales del siglo XV y principios del XVI al servicio de la corona española.

    Full Text Available This article aims to systematize the last decades’ historiographical contributions on the life of Isabel de Villena. In the first section it is shown that, far from being a helpless orphan, Enric de Villena’s daughter could rely on a significant net of uncles, aunts and cousins, which helps understand the author’s choice of Franciscanism. The second section analyzes the true reasons why Isabel de Villena, who possessed an important fortune, was brought up in queen Maria’s court when her father, who had been exiled by the Trastámara brothers, died: as the daughter of the last legitimate male descendant of one of the claimants of the throne of Aragon in the aftermath of Martí l’Humà’s death, her future had to be carefully monitored.[ct] Aquest article pretèn sistematitzar les notícies historiogràfiques de les últimes dècades en allò que pot ser aplicat a augmentar el nostre coneixement de la vida d’Isabel de Villena. En primer lloc es mostra que, lluny de ser una orfeneta desvalguda, la fi lla d’Enric de Villena comptava amb una signifi cativa xarxa d’oncles, ties i cosins, i aquesta ajuda a entendre l’opció de l’autora pel franciscanisme. En la segona part s’analitzen les autèntiques raons de per què Isabel de Villena, que comptava amb una considerable fortuna, va ser integrada a la cort de la reina Maria a la mort del seu pare, que havia estat desterrat pels Trastàmares: com a filla de l’últim descendent masculí legítim d’un dels aspirants al tron d’Aragó a la mort de Martí l’Humà, el seu futur havia de ser supervisat amb compte.

    2007-01-01

    Phosphogypsum (PG), the major waste material in phosphate fertilizer processing, has been known to contain enhanced levels of naturally-occurring radionuclides especially 226 Ra. The lack of radioactivity data regarding Philippine phosphogypsum and its environmental behavior in the Philippine setting has brought concern on possible contamination of groundwater beneath the phosphogypsum ponds in Isabel, Leyte, Philippines. The radioactivity of Philippine phosphogypsum was determined and the leaching of 226 Ra from phosphogypsum and through local soil was quantified. Level of 226 Ra in groundwater samples in Isabel, Leyte, Philippines was also quantified to address the primary concern. It was found that the 226 Ra activity in Philippine phosphogypsum is distributed in a wide range from 91.5 to 935 Bq/kg. As much as 5% of 226 Ra can be leached from Philippine PG with deionized water. In vitro soil leach experiments suggest that the soil in the phosphate fertilizer plant area would be able to deter the intrusion of 226 Ra into the water table. Compared to reported values of natural groundwater levels of 226 Ra, the concentration of this radionuclide in Isabel, Leyte groundwater suggest that there is no 226 Ra intrusion brought about by the presence of phosphogypsum ponds in the area.

    Full Text Available After the fall of the monarchist absolutism, the middle class, whom the economic liberalism gives an unprecedented strength, demands new entertainments, new places to make profitable social relationships and, definitely, new ways to show their influence and power. On the other hand, the shift of political rules allows people to express and gather, even if with some restrictions, and opens the door to the progressive democratization of society, with its cultural consequences. That ensemble of factors leads to the appearance of many different institutions but with a constant feature: the defence of the liberal ideas, the good fellowship and communication among individuals (which includes the recreational side, the cultural divulging and artistic expression. It is at this point that establishments with both musical and educational activity must be taken into account. This essay intends to go through organizations such as Liceo Artístico y Literario, Instituto Español, La Unión, Museo Lírico, El Genio and many other artistic societies which proliferated during the 1830s and 1840s, centres with an intense social and musical activity in Madrid during Isabel II's era. Their influence in this area must be underlined, as devoted to promote performance, composition and, which is highly important, music instruction. The selected society of Madrid could be found there, gathered to learn music rudiments, singing and playing as well as to listen to the repertory in vogue at that time and to take part itself in its performance.

    Tras la caída del absolutismo monárquico, la burguesía, a quien el liberalismo económico dota de una pujanza sin precedentes, demanda nuevos entretenimientos, nuevos espacios para granjearse relaciones sociales convenientes y, en definitiva, nuevas formas para ostentar su influencia y poder.

    Full Text Available A uva Isabel, originária do Sul dos Estados Unidos, é uma das principais cultivares de Vitis labrusca. Atualmente é a cultivar mais difundida na Serra Gaúcha, representando aproximadamente 45% de toda a uva produzida nessa região. Além da elaboração de vinho tinto comum, a Isabel é utilizada para elaboração de vinho rosado e suco e comercializada como uva de mesa. O objetivo do presente trabalho foi determinar as características agronômicas e enológicas da uva Isabel, para elaboração de vinho tinto comum. Para isso, avaliou-se a maturação da uva e realizaram-se estudos para caracterizar o cacho, o mosto e o vinho tinto, nas safras de 1988 a 1994. Os resultados obtidos evidenciaram que a uva Isabel tem cacho pequeno, solto, formado por bagas e sementes grandes. O mosto apresenta cor rosada pouco intensa, tem bom teor de açúcar e baixo nível de ácido málico e acidez total. O vinho tem cor vermelha viva; o aroma é intenso e com acentuada tipicidade varietal; a análise sensorial evidencia que geralmente falta ao vinho equilíbrio e maciez.

Este hecho supuso una dependencia total de París y Londres. Los acontecimientos políticos provocados por las guerras carlistas, la subida al trono de Isabel II y posterior reconocimiento de la reina, causaron un déficit en las arcas del Tesoro español, lo que motivó un endeudamiento continuo que se plasmó en la emisión de Deuda pública, adquirida por subditos belgas, holandeses, franceses y principalmente ingleses.

    2001-12-01

    Full Text Available Leer obras de la escritora chilena Isabel Allende es como escuchar una composición musical polifónica. Voces que han permanecido ignoradas por los compositores de la gran sinfonía latinoamericana salen del silencio para cantar y contar en voz alta lo que la historiografía y la cultura oficial no les ha permitido expresar. Son voces del silencio, voces de las víctimas del rígido sistema patriarcal, victimas de la violencia y de la brutalidad del régimen dictatorial y voces de los marginados, postergados y excluidos de una colectividad conformista y artificial. En cambio las voces escogidas por la escritora para cantar la melodía principal son las femeninas, voces que en el contexto latinoamericano podian desahogarse sólo en el ámbito cerrado del hogar doméstico. Isabel Allende transforma las mujeres que permanecieron excluidas del gran acontecer histórico, de la vida cotidiana, social, cultural y política de su proprio país en las grandes protagonistas de su obra literaria. La dimensión de la mujer latinoamericana que ha sido relegada al silencio y al olvido, a la pasividad, a la subordinación y resignación emerge aquí con una energía vital y transgresora que transforma las protagonistas en figuras determinadas y subversivas que reclaman para elias una transformación y mejoramiento de sus condiciones de existencia.

    Full Text Available Aunque ciertos organismos de la administración del reino están ya asentados en determinados lugares, y se observan algunos indicios de sedentarización, entre ellos el establecimiento de la casa del príncipe Juan en Almazán, la corte de Isabel la Católica sigue siendo itinerante como la de sus antecesores. Con el fin de constatar esta circunstancia, en el presente artículo se estudia el trayecto seguido por Isabel I de Castilla en dos ocasiones, el primer año de reinado, y el último viaje que realiza.

    Full Text Available The work was carried out in four hectares of the «Monument National» Bosque Piedra Isabel Rubio, belonging to the Forest Company Macurije municipality Guane. Ecosystem that possesses national significance because it constitutes a valuable monumental example, it summarizes natural aspects as their calcareous formations of the Jurassic period, besides their intangible values associated to the rural traditions. The objective of the research is to propose a plan of action participative for the restoration of this ecosystem starting from the results obtained in diagnose participative. Among the used scientific methods, they are the research Action Participative and the participant observation, for the collection of information the interview was used in depth, and the meetings in groups. As important results the presence of a strong pressure antropic is obtained on the flora, fauna and rocks of the minimogotes, the introduction of exotic and invasive species, and soil erosion, in consequence the degradation of the ecosystem and loss of the biodiversity. Another significant result constituted it the scarce level of the actors' knowledge regarding the category of this forest and the administrative juridical regulations that govern it. The removed evidences of these communities show that the necessity to diminish the antropics actions and to elevate the sensibility regarding the conservation, they impose a demand of knowledge to satisfy by means of training actions with the participation of the local actors and instrumentation of the regulative apparatus.

    Full Text Available There is an increasing demand for organic grapes by the juice industry of Serra Gaúcha, Brazil. This region presents a humid and hot summer, ideal climatic conditions for the development of a number of diseases. To control such diseases and problems brought about by other organisms, growers apply pesticides on the grapevines which may leave residues in grapes. However, in general, grapes produced by organic system have lower yield, but there is a lack of research data on this subject. Thus, an experiment was carried out over three years in order to compare the yield components and the physicochemical composition of the must of Isabel grapes conducted in both production systems. When the grapes were ripe, variables related to yield components were evaluated, such as the number of clusters/vine, yield/vine and weight/cluster. Then the grapes were sampled and taken to the laboratory where they were crushed and the musts were centrifuged and analyzed. The 3-year data mean were submitted to correlation analysis and Principal Component Analysis. The results show that conventional grapevines produced 2.18 times more than organic. However, the grapes from the organic system had higher density, Brix, pH, Brix/titratable acidity ratio, P and Mg but lower K, and Ca varied little between both production systems.

Desde los estudios de género, y más concretamente desde la teoría fílmica feminista, se ha analizado exhaustivamente un subgénero cinematográfico que se entiende como fundamental, ya que saca a la luz las restricciones que les son impuestas a las mujeres en la sociedad patriarcal en general y más concretamente en la institución familiar. Mi vida sin mí (Isabel Coixet, 2003 se enmarca, en apariencia, dentro del corte clásico del subgénero melodramático familiar para subvertir, después, sus propias convenciones. Isabel Coixet se desmarca conscientemente de la identificación masoquista que proporciona el melodrama a la espectadora, critica la representación clásica de la mujer y se aleja de la oposición predominante en el cine entre maternidad-sexualidad. La directora española construye una mujer como sujeto múltiple, contradictorio y en progreso que no se conforma con proponer vías de resistencia a las imposiciones patriarcales, y que no reduce su identidad a la faceta maternal. La mujer del melodrama de Coixet es útil en tanto modelo de identificación diegético y extradiegético para la organización de un nuevo sistema –social, cinemático, etc.– que no ponga sus bases en el binomio dominación-sumisión.

    The popularity of ecotourism in the marine protected areas of Mexico has increased over the last 10 years; in particular there is a large development of a SCUBA diving industry in the Mexican Pacific including Isabel Island. Given the risks associated with human activity in the marine environments around this island, we propose two ecotourism management strategies: (1) the creation and use of underwater trails, and (2) the estimation of the specific tourism carrying capacity (TCC) for each trail. Six underwater trails were selected in sites that presented elements of biological, geological, and scenic interest, using information obtained during field observations. The methodology used to estimate the TCC was based upon the physical and biological conditions of each site, the infrastructure and equipment available, and the characteristics of the service providers and the administrators of the park. Correction factors of the TCC included elements of the quality of the visit and the threat and vulnerability of the marine environment of each trail (e.g., divers' expertise, size and distance between groups of divers, accessibility, wind, coral coverage). The TCC values ranged between 1,252 and 1,642 dives/year/trail, with a total of 8,597 dives/year for all six trails. Although these numbers are higher than the actual number of recreational visitors to the island (~1,000 dives per year), there is a need for adequate preventive management if the diving sites are to maintain their esthetic appeal and biological characteristics. Such management might be initially directed toward using only the sites and the TCC proposed here.

    Hurricanes are a major threat to coastal communities and infrastructures including nuclear power plants located in low-lying coastal zones. In response, their sensitive elements should be protected by smart design to withstand against drastic impact of such natural phenomena. Accurate and reliable estimate of hurricane attributes is the first step to that effort. Numerical models have extensively grown over the past few years and are effective tools in modeling large scale natural events such as hurricane. The impact of low probability hurricanes on the lower Delaware Bay is investigated using dynamically coupled meteorological, hydrodynamic, and wave components of Delft3D software. Efforts are made to significantly reduce the computational overburden of performing such analysis for the industry, yet keeping the same level of accuracy at the area of study (AOS). The model is comprised of overall and nested domains. The overall model domain includes portion of Atlantic Ocean, Delaware, and Chesapeake bays. The nested model domain includes Delaware Bay, its floodplain, and portion of the continental shelf. This study is portion of a larger modeling effort to study the impact of low probability hurricanes on sensitive infrastructures located at the coastal zones prone to hurricane activity. The AOS is located on the east bank of Delaware Bay almost 16 miles upstream of its mouth. Model generated wind speed, significant wave height, water surface elevation, and current are calibrated for hurricane Isabel (2003). The model calibration results agreed reasonably well with field observations. Furthermore, sensitivity of surge and wave responses to various hurricane parameters was tested. In line with findings from other researchers, accuracy of wind field played a major role in hindcasting the hurricane attributes.

    Full Text Available Despite its ongoing popularity with women readers, romantic fiction has traditionally been regarded as an instrument of women's oppression, largely due to its reinforcement and even glorification of sexual stereotypes and bourgeois values. Latin American writer Isabel Allende's novels The House of the Spirits and Eva Luna both contain a number of the elements and conventions of romantic fiction, including distinct similarities to the two acknowledged foundations of this genre: Charlotte Brontë's Jane Eyre and Emily Brontë's Wuthering Heights.However, The House of the Spirits and Eva Luna can also be read as rewritings of the genre of romantic fiction. In these two texts, Isabel Allende appropriates and then reworks certain conventions of romantic fiction in order to portray her notion of "fulfilling egalitarian relationships" between men and women. Nevertheless, despite these feminist revisions, Allende's rewritten romances do retain the "wish-fulfillment" element-or ideal-of romantic fiction, its depiction of women's fantasy of feminine values being appreciated and validated within heterosexual romantic relationships in the real world.

    Full Text Available ABSTRACT Grape by-products are promising and sustainable sources of anthocyanins. Considering the factors related to degradation of those pigments, spectrophotometric and kinetic analyzes were carried out with the aim to evaluate the light and heat stability of anthocyanins from Isabel grape residue. We found that the exposure to luminosity (80W; 2500 lux and high temperature (= 70ºC significantly affected the absorption and content of those compounds (p <0.05, whose the most stable condition was obtained at 50°C (t1/2: 37.7h; k: 1.84 x 10-2 h-1 and protected from light (t1/2: 3,320.6h; k: 2.09 x 10-4 h-1. Therefore, the anthocyanins from the agroindustrial residue of Isabel grape are an alternative of natural colorants for food that can be packaged in opaque packaging and not subjected to severe heat treatment during processing.

    This study focuses on the heavy rainfall event associated with hurricane Isabel's (2003) passage over the Appalachian mountains of the eastern United States. Specifically, an ensemble consisting of two groups of simulations using the Weather Research and Forecasting model (WRF), with and without topography, is performed to investigate the orographic influences on heavy rainfall and rainfall variability. In general, the simulated ensemble mean with full terrain is able to reproduce the key observed 24-h rainfall amount and distribution, while the flat-terrain mean lacks in this respect. In fact, 30-h rainfall amounts are reduced by 75% with the removal of topography. Rainfall variability is also significantly increased with the presence of orography. Further analysis shows that the complex interaction between the hurricane and terrain along with contributions from varied microphysics, cumulus parametrization, and planetary boundary layer schemes have a pronounced effect on rainfall and rainfall variability. This study follows closely with a previous study, but for a different TC case of Isabel (2003). It is an important sensitivity test for a different TC in a very different environment. This study reveals that the rainfall variability behaves similarly, even with different settings of the environment.

    Full Text Available The Roraima viticulture began in 2003 with the creation of the Vale do Rio Branco project, in which the cultivation of grapes was enlarged for a commercial production. However, no information has been found in literature  about the mineral content of grapes produced. Considering the essentiality and importance of this information for human nutrition, quantification of species K by flame photometry and Ca, Fe and Zn by flame atomic absorption spectrometry in pulps of grapes of the Isabel, Vitis labrusca L. variety, cultivated in Boa Vista/RR has been realized, as well as determination of the physical characteristics of the grape bunches and berries. The determinations´ results indicate that K had the highest concentration, followed by Ca, Fe and Zn, being similar to the data, described in other literature sources, except for Ca, which showed smaller, indicating an intervention demand of culture methods employed to optimize the absorption of this species by vines. The consumption of Isabel grape can contribute to the achievement of the adequate intake recommendations of mineral elements. The results of the physical characterization let us classify Isabel grape bunches to very small, loose and green stalks. Overall, this study reveals new data about the physical characteristics and mineral composition present in Isabel grape grown in Boa Vista/RR.

    Full Text Available AbstractBrazilian wine production is characterized by Vitis labrusca grape varieties, especially the economically important Isabel cultivar, with over 80% of its production destined for table wine production. The objective of this study was to optimize and validate the conditions for extracting volatile compounds from wine with the solid-phase microextraction technique, using the response surface method. Based on the response surface analysis, it can be concluded that the central point values maximize the process of extracting volatile compounds from wine, i.e., an equilibrium time of 15 minutes, an extraction time of 35 minutes, and an extraction temperature of 30 °C. Esters were the most numerous compounds found under these extraction conditions, indicating that wines made from Isabel cultivar grapes are characterized by compounds that confer a fruity aroma; this finding corroborates the scientific literature.

    Goat milk is an attractive food because of its nutritional properties, easy digestibility and hypoallergenicity. Goat milk yogurt is an appropriate matrix for the inclusion of new ingredients such as probiotic cultures, fruit and its derivatives. Grapes are rich in polyphenols and recognized for their health benefits. The aim of this study was to improve the quality characteristics of probiotic goat milk yogurt by the addition of an Isabel grape (Vitis labrusca L.) preparation (IGP). For this, the influence of the addition of IGP on the physicochemical, microbiological and sensory characteristics of goat milk yogurt containing the probiotic Lactobacillus acidophilus LA-05 was evaluated during 28 days of refrigerated storage (5 ± 0.5 °C). Four yogurt formulations were prepared, each varying in the added IGP amount, as follows: Y0 (not containing IGP), YG15 (containing 15 g per 100 mL of IGP), YG20 (containing 20 g per 100 mL of IGP), and YG25 (containing 25 g per 100 mL of IGP). All formulations showed probiotic counts ranging from 7 to 8 log CFU mL -1 over the assessed storage period. The addition of 20 g per 100 mL of IGP affected positively the colour, viscosity, and sensory acceptance of the yogurt formulations. The production of goat milk yogurt containing L. acidophilus LA-05 and IGP is an option for developing a new goat dairy product with added value due to the inclusion of components with potential functional properties.

    Full Text Available Nicolas-Antoine Taunay, French landscape painter, produced also several portraits during his stay at the Rio de Janeiro Court. In this city, in 1816, he paints the queen Carlota Joaquina and all her daughters. In this group, two portraits have a very special way: the paintings still today catalogued as Maria Francisca and Maria Teresa, but probably being Maria Isabel and Maria Francisca de Assis - princesses that, in this year, left Brazil to marry the Spanish King Fernando VII, and his brother Carlos Maria Isidro de Bourbon. In this article, beyond to describe these portraits (and analyse the identities of the portrayed princesses, I analyse their functions in the Court society and the mains artists of this gender in Europe. I will discuss, as well, the hypothesis about the Taunay choices. In this sense, I will analyse the possible circulation of the typologies of portrait between Italy, Portugal, Spain and France, understanding these productions by Taunay and the functions occupied by these portraits in the political relations between Brazil and Europe.

  15. The ‘other’ side of history as depicted in Isabel Allende’s Of Love and Shadows

    Full Text Available The proceedings of the Truth and Reconciliation Commission in South Africa have once again foregrounded the trauma involved in reconstructing a past fraught with political and personal violence and have, at the same time, also illustrated the therapeutic quality of testimony. Literature has always played a vital role in the process of coming to terms with reality. As a woman within a postcolonial context, Isabel Allende bears witness to political oppression and gender discrimination in her novels. They serve as examples of testimonial literature which focus on the plight of women as marginalized citizens and represent a collective conscience in testimony to the atrocities of the past. This is accomplished through the interaction of her fictional characters with a recognizable historical context. In Of Love and Shadows, her female protagonist, Irene, asserts her individuality through writing/reporting which questions the validity of the male-oriented and so-called “objective” historical reportage. By creating disparate and complementary perspectives which accentuate the female/personal as well as the male/public aspects of experience, Allende proposes a recognition of the personal and the peripheral in the documentation of historical events; she underlines the validity of the “other” side of experience and history.

    Full Text Available ABSTRACT It has been demonstrated that rootstocks can influence grape characteristics, but there are few data in literature about the rootstocks influence in the wine characteristics, especially in wines elaborated with Vitis labrusca or hybrid grapes. This study evaluated the influence of ‘IAC 766’ and ‘106-8 Mgt’ rootstocks on the physicochemical characteristics of ‘Bordô’, ‘Isabel’ and ‘IAC 138-22 ‘Máximo’ musts and wines. The musts were evaluated for pH, soluble solids, total acidity and soluble solids/acidity ratio. The wines were evaluated for density, alcohol content; total, volatile and fixed acidity; pH, dry extract, reducing sugars, reduced dry extract, alcohol in weight/reduced dry extract; free and total sulfur dioxide; anthocyanins, polyphenols index (I 280; polyphenols and total flavonoids and antioxidant activity. The ‘Bordô’, ‘Isabel’ and IAC 138-22 ‘Máximo’ musts had low soluble solids for winemaking. The ‘106-8 Mgt’ rootstock promoted higher dry extract content and reduced dry extract in Bordô wine, and lower total and fixed acidity in IAC 138-22 Máximo wine. In Isabel wine, higher pH was promoted by the ‘IAC 766’ rootstock. Aside from low total acidity of the Bordô wine, all the physicochemical characteristics of the wines studied are in accordance with Brazilian law. There was no effect of rootstocks in the phenolics content and antioxidant activity of wines.

  1. Influences of the Saharan Air Layer on the Formation and Intensification of Hurricane Isabel (2003): Analysis of AIRS data and Numerical Simulation

    2006-12-01

    Over the past two decades, little advance has been made in prediction of tropical cyclone intensity while substantial improvements have been made in forecasting hurricane tracks. One reason is that we don't well understand the physical processes that govern tropical cyclone intensity. Recent studies have suggested that the Saharan Air Layer (SAL) may be yet another piece of the puzzle in advancing our understanding of tropical cyclone intensity change in the Atlantic basin. The SAL is an elevated mixed layer, forming as air moves across the vast Sahara Desert, in particular during boreal summer months. The SAL contains warm, dry air as well as a substantial amount of mineral dust, which can affect radiative heating and modify cloud processes. Using the retrieved temperature and humidity profiles from the AIRS suite on the NASA Aqua satellite, the SAL and its influences on the formation and intensification of Hurricane Isabel (2003) are analyzed and simulated with MM5. When the warmth and dryness of the SAL (the thermodynamic effect) is considered by relaxing the model thermodynamic state to the AIRS profiles, MM5 can well simulate the large-scale flow patterns and the activity of Hurricane Isabel in terms of the timing and location of formation and the subsequent track. Compared with the experiment without nudging the AIRS data, it is suggested that the simulated SAL effect may delay the formation and intensification of Hurricane Isabel. This case study generally confirms the argument by Dunion and Velden (2004) that the SAL can suppress Atlantic tropical cyclone activity by increasing the vertical wind shear, reducing the mean relative humidity, and stabilizing the environment at lower levels.

    Full Text Available Abstract Background Glucose-6-phosphate dehydrogenase deficiency poses a significant impediment to primaquine use for the elimination of liver stage infection with Plasmodium vivax and for gametocyte clearance, because of the risk of life-threatening haemolytic anaemia that can occur in G6PD deficient patients. Although a range of methods for screening G6PD deficiency have been described, almost all require skilled personnel, expensive laboratory equipment, freshly collected blood, and are time consuming; factors that render them unsuitable for mass-screening purposes. Methods A published WST8/1-methoxy PMS method was adapted to assay G6PD activity in a 96-well format using dried blood spots, and used it to undertake population screening within a malaria survey undertaken in Isabel Province, Solomon Islands. The assay results were compared to a biochemical test and a recently marketed rapid diagnostic test. Results Comparative testing with biochemical and rapid diagnostic test indicated that results obtained by filter paper assay were accurate providing that blood spots were assayed within 5 days when stored at ambient temperature and 10 days when stored at 4 degrees. Screening of 8541 people from 41 villages in Isabel Province, Solomon Islands revealed the prevalence of G6PD deficiency as defined by enzyme activity Conclusions The assay enabled simple and quick semi-quantitative population screening in a malaria-endemic region. The study indicated a high prevalence of G6PD deficiency in Isabel Province and highlights the critical need to consider G6PD deficiency in the context of P. vivax malaria elimination strategies in Solomon Islands, particularly in light of the potential role of primaquine mass drug administration.

    Full Text Available De todos los libros de cuentas de John Isham tan sólo se conservan dos Libros Mayores. Representan el esfuerzo continuado, durante un intervalo de doce años, para confeccionar un balance de situación. Es indudable que John Isham se había familiarizado con los rudimentos del arte de la teneduría de libros durante su periodo de aprendiz, bajo la supervisión de su patrón, probablemente en Amberes. El uso que hace de la partida doble, aunque sólo ocupa una pequeña parte del primer Libro Mayor y ninguna del segundo, indica que apostaba por el progreso.El valor de estos dos Libros Mayores del siglo XVI es grande, pues nos dice mucho de la estructura de la exportación de paños, usos que un mercader mediano hace de su capital y otros aspectos dfíciles de averiguar por otras vías. En ambos volúmenes las partidas recogen multitud de detalles que nos hablan del entramado del comercio internacional inglés en el floreciente reinado de Isabel I. Al lado de la parida dole aparecen las compañías gremiales que concedieron al comercio inglés la fueza y el esplendor sobre los que se asentó el Imperio Británico.Out of all the account books of John Isham, only two ledgers are preserved at present. They represent a constant effort, for a twelve-year interval, in order to produce a balance sheet. John Isham, no doubt, had learnt the technicalities of the art of bookkeeping duritng his appenticeship period, under his master's supervision, probably in Antwerp. His use of the double entry system, despite it si only present in some sections of the first ledger and none of the second, it is a clear indication that he favoured progress.The value of these two ledgers is remarkable. They talk about the structure of cloth exportation, how a medium-sized merchant used his capital and some other aspects which are difficult to find out through other means. In both volumes entries release multiple details which tell us about the international English commerce

    The Port Isabel fold belt is situated at the northwestern corner of the deep water Gulf of Mexico where the regional E-W trending Texas-Louisiana shelf bends into the NNE-SSW trend of the East Mexico Shelf. The fold belt forms an allochthonous wedge that ramps up from West to East with its front occupied by shallow salt complexes (local canopies). It is assumed that the belt predominantly comprises Oligocene siliciclastic sequences which reveal eastward facing folds and thrusts with a NE-SW regional trend. The structural architecture of the fold belt is very well imaged on recently processed 3D seismic volumes. Crystal III is a wide-azimuth survey acquired in 2011 and reprocessed in 2016 leveraging newly developed state-of-the-art technology. 3D deghosting, directional designature and multi-model 3D SRME resulted in broader frequency spectrum. The new image benefits from unique implementation of FWI, combined with classic tomographic updates. Seismically transparent zones indicating over-pressured shales are limited to the core of anticlines or to the footwall of internal thrust. Mobile shales associated with diapirs are absent in the study area. In contrast, salt is mobile and apparently forms the major decollement of the PIFB as indicated by remnant salt preferentially located in triangles along the major thrusts and fault intersections or at the core of anticlines. Shallow salt diapirs seam to root in the fold belt, while lacking evidence for salt feeders being connected to the deep salt underlying the Mesozoic to Paleogene substratum of the fold belt. Towards the WNW the fold belt is transient into a extensional regime, characterized by roll-over structures associated with deep reaching normal faults which form ultra-deep mini basins filled with Neogene deposits. Kinematic restorations confirm the simultaneous evolution of the deep mini basins and the outboard fold belt. This resembles a gravitational spreading system with the extensional tectonics of the deep

    Full Text Available Abstract Background In 2009, Santa Isabel Province in the Solomon Islands embarked on a malaria elimination programme. However, very little is known in the Province about the anopheline fauna, which species are vectors, their bionomics and how they may respond to intensified intervention measures. The purpose of this study was to provide baseline data on the malaria vectors and to ascertain the possibility of successfully eliminating malaria using the existing conventional vector control measures, such as indoor residual spraying (IRS and long-lasting insecticidal nets (LLIN. Methods Entomological surveys were undertaken during October 2009. To determine species composition and distribution larval surveys were conducted across on the whole island. For malaria transmission studies, adult anophelines were sampled using human landing catches from two villages - one coastal and one inland. Results Five Anopheles species were found on Santa Isabel: Anopheles farauti, Anopheles hinesorum, Anopheles lungae, Anopheles solomonis, and Anopheles nataliae. Anopheles hinesorum was the most widespread species. Anopheles farauti was abundant, but found only on the coast. Anopheles punctulatus and Anopheles koliensis were not found. Anopheles farauti was the only species found biting in the coastal village, it was incriminated as a vector in this study; it fed early in the night but equally so indoors and outdoors, and had a low survival rate. Anopheles solomonis was the main species biting humans in the inland village, it was extremely exophagic, with low survival rates, and readily fed on pigs. Conclusion The disappearance of the two major vectors, An. punctulatus and An. koliensis, from Santa Isabel and the predominance of An. hinesorum, a non-vector species may facilitate malaria elimination measures. Anopheles farauti was identified as the main coastal vector with An. solomonis as a possible inland vector. The behaviour of An. solomonis is novel as it has

Com este objetivo, avaliou-se o efeito das safras de 1999, 2000 e 2001 na composição da uva, do mosto e do vinho Isabel da Serra Gaúcha. Nesse sentido, foram selecionados vinte e dois produtores de uva Isabel de onze municípios dessa região. Por ocasião da maturação, para as avaliações da uva e do mosto e a elaboração das microvinificações, foram colhidos 60kg de uva de cada viticultor. A safra vitícola interferiu significativamente no peso do cacho e da baga, mas não alterou a relação peso da ráquis/peso do cacho. No mosto, observaram-se diferenças em todas as variáveis, exceto para a relação degreesBrix/acidez total. No vinho, teve efeito na maior parte das variáveis avaliadas, com exceção aos cátions K, Mn, Cu e Rb. Em geral, a safra de 1999 foi a melhor, pois apresentou parâmetros mais adequados de acidez total, extrato seco, extrato seco reduzido, alcalinidade das cinzas, taninos, antocianinas e glicerol, variáveis essas que determinam a estrutura e a cor dos vinhos, importantes fatores para sua qualidade.

  11. Effects of Aquifer Development and Changes in Irrigation Practices on Ground-Water Availability in the Santa Isabel Area, Puerto Rico

    Science.gov (United States)

    Kuniansky, Eve L.; Gómez-Gómez, Fernando; Torres-Gonzalez, Sigfredo

    2003-01-01

    The alluvial aquifer in the area of Santa Isabel is located within the South Coastal Plain aquifer of Puerto Rico. Variations in precipitation, changes in irrigation practices, and increasing public-supply water demand have been the primary factors controlling water-level fluctuations within the aquifer. Until the late 1970s, much of the land in the study area was irrigated using inefficient furrow flooding methods that required large volumes of both surface and ground water. A gradual shift in irrigation practices from furrow systems to more efficient micro-drip irrigation systems occurred between the late 1970s and the late 1980s. Irrigation return flow from the furrow-irrigation systems was a major component of recharge to the aquifer. By the early 1990s, furrow-type systems had been replaced by the micro-drip irrigation systems. Water levels declined about 20 feet in the aquifer from 1985 until present (February 2003). The main effect of the changes in agricultural practices is the reduction in recharge to the aquifer and total irrigation withdrawals. Increases in ground-water withdrawals for public supply offset the reduction in ground-water withdrawals for irrigation such that the total estimated pumping rate in 2003 was only 8 percent less than in 1987. Micro-drip irrigation resulted in the loss of irrigation return flow to the aquifer. These changes resulted in lowering the water table below sea level over most of the Santa Isabel area. By 2002, lowering of the water table reversed the natural discharge along the coast and resulted in the inland movement of seawater, which may result in increased salinity of the aquifer, as had occurred in other parts of the South Coastal Plain. Management alternatives for the South Coastal Plain aquifer in the vicinity of Santa Isabel include limiting groundwater withdrawals or implementing artificial recharge measures. Another alternative for the prevention of saltwater intrusion is to inject freshwater or treated sewage

Importam por contribuírem para a criação de histórias e memórias - oficiais e não-oficiais - que atuam na construção de identidades e representações sociais que, por sua vez, orientam as práticas dos moradores dessas localidades.Based on an ethnography carried out in a community center in Morro dos Macacos, located in Bairro de Vila Isabel, a district in the Northern section of Rio de Janeiro city (Brazil, the present article is about the history and memories of that slum and neighborhood. It examines some events that reinforce its official history and memory or emphasize other stories and memories, different or alike. Those events are interesting symbolical expressions of individuals and groups, for they give visibility to social networks, since they reinforce a sense of belonging to a group and create social links. They are also important for contributing to create stories and memories - official and unofficial - that build social identities and representations that guide its inhabitants’ practices.

  15. Effects of changing irrigation practices on the ground-water hydrology of the Santa Isabel-Juana Diaz area, south central Puerto Rico

    Science.gov (United States)

    Ramos-Gines, Orlando

    1994-01-01

    Prior to 1930, the principal source of water for irrigation in the Santa Isabel-Juana Diaz area was surface water from outside the study area, which was delivered by a complex channel-pond system. Recharge from water applied to the fields, estimated to be 18.7 million of gallons per day, and discharge by ground-water flow to sea, estimated to be 17 million of gallons per day, were the major water- budget components prior to intensive development of the ground-water resources. Development of the ground-water resources after 1930 resulted in a substantial increase in irrigation, primarily furrow irrigation. The surface water supplied by the complex channel-pond system continued to be used and ground-water withdrawals increased sub- stantially. By 1966-68, ground-water recharge from irrigation water applied to the fields, estimated to be 37 million of gallons per day, and discharge by pumpage for irrigation, estimated to be 77 million of gallons per day, were the two major components of the ground-water budget. By 1987, drip irrigation had become the principal method of irrigation in the study area, and surface-water irrigation had, for the most part, been discontinued. The estimated aquifer recharge from irrigation water in 1987 was about 6.6 million of gallons per day, which occurred primarily in the remaining fields where furrow irrigation was still practiced. Although aquifer recharge had been reduced as a result of the conversion from furrow to drip irrigation, water levels in the aquifer were higher in 1987 than in 1968 because of the large reduction in ground-water withdrawals and subsequent recovery of ground-water levels.

  16. The Literal and the Literary: A Note on the Historical References in Isabel Allende's La casa de los espíritus

    2003-06-01

    Full Text Available Stripped of much of its individuality as a piece of literature and relegated to the niche set aside for women's writing, Isabel Allende's La casa de los espíritus has sometimes wrongfully been critically condemned as a mere facsimile of García Màrquez's seminal Latin American novel. However, if critics were to reexamine La casa de los espíritus as a work of fiction in which its writer attempts to give voice to, and achieve personal closure of, historical events so tragically real for her, its comparisons with that "other" Latin American novel might be less frequent. This article contends that Allende uses a mixture of traceable historical facts, unsubstantiated personal accounts, and urban myths perpetuated by popular hearsay to present a plausible version of what could have happened during the events surrounding the fall of Salvador Allende on September 11, 1973. The crux of the argument presented will be that by superimposing unsubstantiated or distorted fact and local myth, Allende calls into play an understanding of traceable historical referents and creates a sense of associative identification between the reader and the text and the characters within. This reconstituted image provides a reinterpretation of what happened, a plausible scenario by means of which one can negotiate or interpret the varying shades of "truth" associated with the events as they may have occurred. This article further argues that through the use of familiar and identifiable images of a closer-to-the-fact fictionalization of real historical incidences, Allende is able to create a more credible characterization and historicity in the novel as well as sensitise her target reader to the resultant social and political changes of what many of her countrymen consider the single most fateful day in their nation's history.

    Full Text Available The Madrid Royal Schools of Saint Elizabeth and Loreto were founded by Philip II at the end of 16th Century. Both institutions provided education for orphan girls. They still exist as Catholic coeducational schools granted by the Education Department. These two Schools were Royal Sponsorship belonging to Palace ecclesiastical jurisdiction. The Schools Constitutions sanctioned by Philip V have been preserved until now. Although these Schools have a parallel history, the mentioned Constitutions are completely different for each School. According to these Norms, the Madrid Royal Schools of Saint Elizabeth and Loreto have many differences between them.Los Reales Colegios de Santa Isabel y Loreto de Madrid para niñas huérfanas fueron fundados por Felipe II a finales del siglo XVI. Ambas instituciones siguen funcionando en la actualidad como centros educativos católicos mixtos y concertados. Los dos fueron patronatos reales pertenecientes a la jurisdicción eclesiástica de Palacio. Se han conservado las Constituciones de ambos aprobadas bajo el reinado de Felipe V. Aunque los Colegios tienen una historia paralela, la citada normativa es muy diferente para cada institución; según las Constituciones, Santa Isabel y Loreto tienen más aspectos diferenciadores que comunes.

    Full Text Available The aim of this paper is make known the unpublished correspondence maintained between the Infanta Isabel Clara Eugenia and the Marquis of Velada, her lord high steward for a period of eleven years in the early seventeenth century. This private correspondence has become a vital source of information, especially for the historiography of the court, specifically in comparison with official correspondence. The content of the letters brings nuance and personal judgements which, by virtue of the freedom with which they were written, prove to have a much greater value than the public documents. Certainly, the letters not only transmitted news but also became a powerful means for maintaining the relationship over a considerable distance. This correspondence provides a number of insights into the political and personal relations between a princess and a courtier. The article also includes a transcription and abstract of the letters.

La présence d’une femme sur le trône de Castille fut, pour les chroniqueurs, l’occasion de condenser dans une série de scènes d’une grande intensité littéraire, le rapprochement compliqué, non sans négociations, qui fit de Rodrigo Ponce de León, l’adversaire redouté, un héros, voire une icône du projet politique des Rois Catholiques. Palencia, Valera, Pulgar ou encore Bernáldez, entre autres, proposent des versions parfois divergentes où ils attribuent, moyennant quelques écarts sensibles, un rôle plus ou moins important à Isabelle dans sa réconciliation avec le marquis. Mais au-delà des intérêts et des marques de loyauté des chroniqueurs, la présence même de la reine est un moyen de compléter le profil guerrier de ce héros de la frontière par l’évocation de manifestations de courtoisie des plus raffinées.Se analiza aquí la plasmación cronística del complejo proceso de sumisión de la Casa de Arcos a la nueva monarquía encarnada por la reina Isabel. No en vano, la presencia de una mujer en el trono de Castilla brindó a los cronistas la posibilidad de condensar en una serie de escenas de gran intensidad literaria el complicado acercamiento, no exento de negociaciones, que transformó a Rodrigo Ponce de León de adversario temido en héroe e incluso icono del proyecto político de los Reyes Católicos. Palencia, Valera, Pulgar o Bernáldez, entre otros, ofrecen relatos no siempre coincidentes que divergen de manera sensible al conceder a Isabel mayor o menor protagonismo en la reconciliación con el marqués. Pero más allá de los intereses y lealtades de los cronistas, la propia presencia de la reina les permite completar el perfil guerrero del héroe fronterizo con las más refinadas manifestaciones de cortesía.

Aunque su destacada posición social les permitió intervenir en la escena pública de Medellín, dominada por esquemas masculinos, en parte como un legado de ese poder letrado del siglo XIX, estuvieron al margen, pues no contaron con educación superior y, dentro de la escena cultural, su actividad intelectual se asoció generalmente a las figuras masculinas que las rodearon durante sus vidas. Así mismo, sus producciones fueron identificadas con los denominados géneros menores: crónica, cuento y pequeñas obras teatrales, que se consideraban aceptables y propicias para las mujeres. Sin embargo, sus comedias presentan una visión renovada, y a veces transgredida, sobre los estereotipos de género de la época.

    In April 2013, a consortium of regional health ministries, nongovernmental organizations, aid agencies, clinical specialists and researchers from diverse sectors convened in San Salvador to discuss the epidemic of chronic kidney disease of unknown or non-traditional causes (CKDu) plaguing agricultural communities in Central America and beyond. The three-day meeting, where presentation of research on the clinical and epidemiological characteristics of CKDu roused significant debate, led the Pan American Health Organization to declare CKDu "a pressing and serious health problem [which] represents a burden for families, communities, health systems and society as a whole."[1] This High-level Meeting on Chronic Kidney Disease of Non-Traditional Causes in Central America (24-26 April) followed several international meetings at which Dr María Isabel Rodríguez, El Salvador's Minister of Health, presented studies on the disease burden in her country, where end-stage renal disease is the leading cause of hospital deaths. She outlined results of original scientific research by Dr Carlos Orantes (first published in MEDICC Review), that described an "elevated prevalence of chronic kidney disease, chronic renal failure and risk factors" among the patients studied, noting that "the most common [form] was chronic kidney disease of unknown cause, associated with neither diabetes nor hypertension."[2] In this interview with MEDICC Review, Dr Rodríguez discussed the gravity of the problem in Salvadoran agricultural communities; the importance of CKDu research in other countries; and the urgent need for intersectoral action and active community participation to confront and control the epidemic.

El análisis morfológico y métrico revela que las muestras de oso de Santa Isabel se agrupan bien con las de U. deningeri de La Lucia y de la Sima de los huesos, pero con caracteres ligeramente más evolucionados a los de esta última, existiendo una gran distancia métrica morfológica con las poblaciones de U. spelaeus. El análisis de la racemización del ácido del colágeno de la dentina de las poblaciones de oso de las cavernas de la Península Ibérica ha permitido establecer que los osos de la Cueva de Santa Isabel son sincrónimos, o tal vez, algo más antiguos que los de la Sima de los Huesos. La ligera discrepancia existente entre la bioestratigrafía deducida a partir de la morfología dental y la obtenida mediante análisis de la racemización del ácido aspártico, se podría explicar por diferencias en las condiciones tafonómicas del yacimiento y/o un inferior número de muestras para el yacimiento de Santa Isabel.

A presente pesquisa analisou parte do bairro viamonense Santa Isabel, especialmente a vila Jardim Universitário, localizado na divisa com o Campus do Vale da Universidade Federal do Rio Grande do Sul (UFRGS, este em Porto Alegre (POA. Partindo da questão se o Campus do Vale influenciou na expansão da urbanização do seu entorno, os principais instrumentos de coleta de dados foram a entrevista e o questionário com os moradores locais, totalizando 354 pessoas. Segundo 62,7% desses, a UFRGS foi responsável pela expansão da urbanização. Embora quantitativamente os valores encontrados apontem essa responsabilidade ao campus, outros fatores também foram importantes, como o caso do valor do uso do solo. Em um primeiro momento o bairro se constituiu como uma alternativa viável para a residência, devido o preço dos lotes e a localização próxima à capital, beneficiando aqueles que trabalhavam em POA. Em um segundo momento, no final da década de 1970 – a partir da construção do Campus do Vale – observou-se a expansão da urbanização com o aumento da população e a redução de áreas vazias para dar espaço à construção civil. Em campo analisou-se a grande relação que há entre moradores e os pontos de serviços oferecidos nas dependências da universidade, como é o caso do terminal de ônibus, agências bancárias e farmácia, além de gerar empregos e valorizar os imóveis próximos, dada a importância do aluguel para os estudantes.

    On September 21 - 23, 2003, the United States Geological Survey (USGS) conducted an oblique aerial photographic survey along the Atlantic coast from Ocean City, Md., to Fort Caswell, N.C., and inland oblique aerial photographic survey from Waynesboro to Redwood, Va., aboard a Navajo Piper twin-engine airplane. The coastal survey was conducted at an altitude of 500 feet (ft) and approximately 1,000 ft offshore. For the inland photos, the aircraft tried to stay approximately 500 ft above the terrain. These coastal photos were used to document coastal changes like beach erosion and overwash caused by Hurricane Isabel, while the inland photos looked for potential landslides caused by heavy rains. The photos may also be used as baseline data for future coastal change analysis. The USGS and the National Aeronautics and Space Administration (NASA) surveyed the impact zone of Hurricane Isabel to better understand the changes in vulnerability of the Nation’s coasts to extreme storms (Morgan, 2009). This report serves as an archive of photographs collected during the September 21 - 23, 2003, post-Hurricane Isabel coastal and inland oblique aerial survey along with associated survey maps, KML files, navigation files, digital Field Activity Collection System (FACS) logs, and Federal Geographic Data Committee (FGDC) metadata.

Muitos autores a relacionava somente com a preservação e ações conservacionistas do meio ambiente, mas sua dimensão vai além, a exemplo da própria interação entre os sujeitos como uma dessas propostas. Nesse sentido, este artigo é resultado de um projeto do programa de Iniciação Cientifica e Tecnológica (PIBICT. O objetivo deste trabalho é identificar a importância da EA no processo de construção e execução do Projeto Político Pedagógico (PPP nas escolas municipais de Princesa Isabel – PB. A metodologia se fez por meio de entrevistas e aplicação de questionários, além de análise documental do PPP existente, do regimento escolar, do plano de desenvolvimento da escola, do projeto Selo Verde na Escola: pensar, sentir e agir e do Projeto COM-VIDA. Ademais, as observações/conversas informais durante os contatos com a escola e seus atores sociais também foram valorizadas. Os resultados da pesquisa mostraram que as escolas municipais urbanas de Princesa Isabel ainda estão atreladas a uma visão reducionista da temática ambiental, pois não conseguem, ainda, identificar a EA como um processo amplo, em que a relação sociedade/natureza está presente, tendo muitas vezes a percepção de conscientização à preservação ao meio ambiente, mas não priorizam as interações entre os sujeitos e destes com o meio por meio de atividades cotidianas.

    Full Text Available We comprehend the learning room as a space where teachers and students knowledge cross it other, permeated by the idiosyncrasies from the society that surrounds the school. This study aims know the pedagogical practice of two teachers in the history teaching for the formers years of the fundamental school, to comprehend as the work that they develop interfere in the student’s historical knowledge construction. The study of case method of survey had the contribution of the teachers of two municipal schools from Londrina. The data, collected through the observation inside the learning room and semi structured interviews with the teachers, were analyzed from the theoretical assumptions announced by Isabel Barca, Hilary Cooper and Keity Barton. We concluded that there are similarities and differences on the teacher’s practice and the students behavior in both classrooms. From a general view, the work with the history is based, nearly exclusively, in the didactical book reading and in the demand to the students retain the information from it. There’s a silence in front of the questions raised by the students about the content and the mechanisms that permit the students to comprehend that the past can have many interpretations are inexistent.

    Blended Learning has been implemented, evaluated and researched for the last decades within different educational areas and levels. Blended learning has been coupled with different epistemological understandings and learning theories, but the fundamental character and dimensions of learning...... in blended learning are still insufficient. Moreover, blended learning is a misleading concept described as learning, despite the fact that it fundamentally is an instructional and didactic approach (Oliver & Trigwell, 2005) addressing the learning environment (Inglis, Palipoana, Trenhom & Ward, 2011......) instead of the learning processes behind. Much of the existing research within the field seems to miss this perspective. The consequence is a lack of acknowledgement of the driven forces behind the context and the instructional design limiting the knowledge foundation of learning in blended learning. Thus...

  5. Learn, how to learn

    Narayanan, M.

    2002-12-01

    Ernest L. Boyer, in his 1990 book, "Scholarship Reconsidered: Priorities of the Professorate" cites some ground breaking studies and offers a new paradigm that identifies the need to recognize the growing conversation about teaching, scholarship and research in the Universities. The use of `ACORN' model suggested by Hawkins and Winter to conquer and mastering change, may offer some helpful hints for the novice professor, whose primary objective might be to teach students to `learn how to learn'. Action : It is possible to effectively change things only when a teaching professor actually tries out a new idea. Communication : Changes are successful only when the new ideas effectively communicated and implemented. Ownership : Support for change is extremely important and is critical. Only strong commitment for accepting changes demonstrates genuine leadership. Reflection : Feedback helps towards thoughtful evaluation of the changes implemented. Only reflection can provide a tool for continuous improvement. Nurture : Implemented changes deliver results only when nurtured and promoted with necessary support systems, documentation and infrastructures. Inspired by the ACORN model, the author experimented on implementing certain principles of `Total Quality Management' in the classroom. The author believes that observing the following twenty principles would indeed help the student learners how to learn, on their own towards achieving the goal of `Lifelong Learning'. The author uses an acronym : QUOTES : Quality Underscored On Teaching Excellence Strategy, to describe his methods for improving classroom teacher-learner participation. 1. Break down all barriers. 2. Create consistency of purpose with a plan. 3. Adopt the new philosophy of quality. 4. Establish high Standards. 5. Establish Targets / Goals. 6. Reduce dependence on Lectures. 7. Employ Modern Methods. 8. Control the Process. 9. Organize to reach goals. 10. Prevention vs. Correction. 11. Periodic Improvements. 12

    Hasse, Cathrine

    This book shall explore the concept of learning from the new perspective of the posthuman. The vast majority of cognitive, behavioral and part of the constructionist learning theories operate with an autonomous individual who learn in a world of separate objects. Technology is (if mentioned at all......) understood as separate from the individual learner and perceived as tools. Learning theory has in general not been acknowledging materiality in their theorizing about what learning is. A new posthuman learning theory is needed to keep up with the transformations of human learning resulting from new...... technological experiences. One definition of learning is that it is a relatively permanent change in behavior as the result of experience. During the first half of the twentieth century, two theoretical approaches dominated the domain of learning theory: the schools of thought commonly known as behaviorism...

    Full Text Available What You Understand Is What Your Cognitive Integrates. Scientific research develops, as a native environment, knowledge. This environment consists of two interdependent divisions: theory and technology. First division occurs as a recursive research, while the second one becomes an application of the research activity. Over time, theories integrate methodologies and technology extends as infrastructure. The engine of this environment is learning, as the human activity of knowledge work. The threshold term of this model is the concepts map; it is based on Bloom’ taxonomy for the cognitive domain and highlights the notion of software scaffolding which is grounded in Vygotsky’s Social Development Theory with its major theme, Zone of Proximal Development. This article is designed as a conceptual paper, which analyzes specific structures of this type of educational research: the model reflects a foundation for a theory and finally, the theory evolves as groundwork for a system. The outcomes of this kind of approach are the examples, which are, theoretically, learning outcomes, and practically exist as educational objects, so-called e-learning.

    Full Text Available A vast array of economical, social, political, cultural and other factors influences the transformed role of learning and education in the society, as well as the functioning of local community and its social and communication patterns. The influences which are manifested as global problems can only be successfully solved on the level of local community. Analogously with the society in general, there is a great need of transforming a local community into a learning, flexible and interconnected environment which takes into account different interests, wishes and needs regarding learning and being active. The fundamental answer to changes is the strategy of lifelong learning and education which requires reorganisation of all walks of life (work, free time, family, mass media, culture, sport, education and transforming of organisations into learning organisations. With learning society based on networks of knowledge individuals are turning into learning individuals, and organisations into learning organisations; people who learn take the responsibility of their progress, learning denotes partnership among learning people, teachers, parents, employers and local community, so that they work together to achieve better results.

    2008-03-01

    Full Text Available Mimetic learning, learning by imitation, constitutes one of the most important forms of learning. Mimetic learning does not, however, just denote mere imitation or copying: Rather, it is a process by which the act of relating to other persons and worlds in a mimetic way leads to an en-hancement of one’s own world view, action, and behaviour. Mimetic learning is productive; it is related to the body, and it establishes a connection between the individual and the world as well as other persons; it creates practical knowledge, which is what makes it constitutive of social, artistic, and practical action. Mimetic learning is cultural learning, and as such it is crucial to teaching and education (Wulf, 2004; 2005.

    2016-01-01

    Deep learning is a form of machine learning that enables computers to learn from experience and understand the world in terms of a hierarchy of concepts. Because the computer gathers knowledge from experience, there is no need for a human computer operator to formally specify all the knowledge that the computer needs. The hierarchy of concepts allows the computer to learn complicated concepts by building them out of simpler ones; a graph of these hierarchies would be many layers deep. This book introduces a broad range of topics in deep learning. The text offers mathematical and conceptual background, covering relevant concepts in linear algebra, probability theory and information theory, numerical computation, and machine learning. It describes deep learning techniques used by practitioners in industry, including deep feedforward networks, regularization, optimization algorithms, convolutional networks, sequence modeling, and practical methodology; and it surveys such applications as natural language proces...

    We consider research and theory relevant to the notion of informal learning. Beginning with historical and definitional issues, we argue that learning happens not just in schools or in school-aged children. Many theorists have contrasted informal learning with formal learning. Moving beyond this dichotomy, and away from a focus on where learning occurs, we discuss five dimensions of informal learning that are drawn from the literature: (1) non-didactive, (2) highly socially collaborative, (3) embedded in meaningful activity, (4) initiated by learner's interest or choice, and (5) removed from external assessment. We consider these dimensions in the context of four sample domains: learning a first language, learning about the mind and emotions within families and communities, learning about science in family conversations and museum settings, and workplace learning. Finally, we conclude by considering convergences and divergences across the different literatures and suggesting areas for future research.

    Machine learning, which builds on ideas in computer science, statistics, and optimization, focuses on developing algorithms to identify patterns and regularities in data, and using these learned patterns to make predictions on new observations. Boosted by its industrial and commercial applications, the field of machine learning is quickly evolving and expanding. Recent advances have seen great success in the realms of computer vision, natural language processing, and broadly in data science. Many of these techniques have already been applied in particle physics, for instance for particle identification, detector monitoring, and the optimization of computer resources. Modern machine learning approaches, such as deep learning, are only just beginning to be applied to the analysis of High Energy Physics data to approach more and more complex problems. These classes will review the framework behind machine learning and discuss recent developments in the field.

    2017-07-10

    Perceptual learning refers to how experience can change the way we perceive sights, sounds, smells, tastes, and touch. Examples abound: music training improves our ability to discern tones; experience with food and wines can refine our pallet (and unfortunately more quickly empty our wallet), and with years of training radiologists learn to save lives by discerning subtle details of images that escape the notice of untrained viewers. We often take perceptual learning for granted, but it has a profound impact on how we perceive the world. In this Primer, I will explain how perceptual learning is transformative in guiding our perceptual processes, how research into perceptual learning provides insight into fundamental mechanisms of learning and brain processes, and how knowledge of perceptual learning can be used to develop more effective training approaches for those requiring expert perceptual skills or those in need of perceptual rehabilitation (such as individuals with poor vision). I will make a case that perceptual learning is ubiquitous, scientifically interesting, and has substantial practical utility to us all. Copyright © 2017. Published by Elsevier Ltd.

I have established that a form of learning, such as distance learning definitely contributes to a higher learning quality and leads to innovative, dynamic and knowledgebased society. Knowledge and skills enable individuals to cope with and manage changes, solve problems and also create new knowledge. Traditional learning practices face new circumstances, new and modern technologies appear, which enable quick and quality-oriented knowledge implementation. The centre of learning process at distance learning is to increase the quality of life of citizens, their competitiveness on the workforce market and ensure higher economic growth. Intellectual capital is the one, which represents the biggest capital of each society and knowledge is the key factor for succes of everybody, who are fully aware of this. Flexibility, openness and willingness of people to follow new IT solutions form suitable environment for developing and deciding to take up distance learning.

    The absence of a robust and unified theory of cyber dynamics presents challenges and opportunities for using machine learning based data-driven approaches to further the understanding of the behavior of such complex systems. Analysts can also use machine learning approaches to gain operational insights. In order to be operationally beneficial, cybersecurity machine learning based models need to have the ability to: (1) represent a real-world system, (2) infer system properties, and (3) learn and adapt based on expert knowledge and observations. Probabilistic models and Probabilistic graphical models provide these necessary properties and are further explored in this chapter. Bayesian Networks and Hidden Markov Models are introduced as an example of a widely used data driven classification/modeling strategy.

    2018-01-01

    Is leadership a result of inheritance or is it something one learns during formal learning in e.g. business schools? This is the essential question addressed in this article. The article is based on a case study involving a new leader in charge of a group of profession practitioners. The leader...... promotes his leadership as a profession comparable to the professions of practitioners. This promotion implies that leadership is something one can and probably must learn during formal learning. The practitioners on the other hand reject this comprehension of leadership and long for a fellow practitioner...... to lead the organization. While asked they are unable to describe how, where and when they think a practitioner develops leadership skills necessary for leading fellows. In the following we will start analysing the case in order to comprehend and discuss both the professional leaders and the practitioners...

    Pimentel, Ricardo; Noguira, Eloy Eros da Silva; Elkjær, Bente

    The article presents a study that aims at the apprehension of the group learning in a top management team composed by teachers in a Brazilian Waldorf school whose management is collective. After deciding to extend the school, they had problems recruiting teachers who were already trained based...... on the Steiner´s ideas, which created practical problems for conducting management activities. The research seeks to understand how that group of teachers collectively manage the school, facing the lack of resources, a significant heterogeneity in the relationships, and the conflicts and contradictions......, and they are interrelated to the group learning as the construction, maintenance and reconstruction of the intelligibility of practices. From this perspective, it can be said that learning is a practice and not an exceptional phenomenon. Building, maintaining and rebuilding the intelligibility is the group learning...

  20. Transforming learning?

    Science.gov (United States)

    1999-09-01

    A new Learning and Skills Council for post-16 learning is the latest proposal from the UK Government in its attempt to ensure a highly skilled workforce for the next century. Other aims will be to reduce the variability in standards of the existing post-16 system, coordination and coherence between further education and training, and a reduction in the duplication and layers in contracting and funding. The proposals include: a national Learning and Skills Council, with 40-50 local Learning and Skills Councils to develop local plans; a strengthened strategic role for business in education and training, influencing a budget of #5bn a radical new youth programme entitled `Connexions', with dedicated personal advisors for young people; greater cooperation between sixth forms and colleges; and the establishment of an independent inspectorate covering all work-related learning and training, to include a new role for Ofsted in inspecting the provision for 16-19 year-olds in schools and colleges. It is hoped that this programme will build on the successes of the previous systems and that savings of at least #50m can be achieved through streamlining and the reduction in bureaucracy. The intentions are set out in a White Paper, Learning to Succeed, which is available from the Stationery Office and bookshops, as well as on the website www.dfee.gov.uk/post16. Published in addition to the White Paper was `School Sixth form funding: a consultation paper' (available from DfEE publications, Prolog, PO Box 5050, Sherwood Park, Annesley, Nottingham NG15 0DJ) and `Transition plan for the post-16 education and training and for local delivery of support for small firms' (available from Trevor Tucknutt, TECSOP Division, Level 3, Department for Education and Employment, Moorfoot, Sheffield S1 4PQ). The deadline for comments on both the sixth form consultation document and the White Paper is 15 October 1999. Almost simultaneously with the announcement of the above proposals came the

    OpenAIRE

    Bott, Lewis; Hoffman, Aaron B.; Murphy, Gregory L.

    2007-01-01

    Many theories of category learning assume that learning is driven by a need to minimize classification error. When there is no classification error, therefore, learning of individual features should be negligible. We tested this hypothesis by conducting three category learning experiments adapted from an associative learning blocking paradigm. Contrary to an error-driven account of learning, participants learned a wide range of information when they learned about categories, and blocking effe...

  16. Learning Physics

    International Nuclear Information System (INIS)

    Cohen, E.

    2005-01-01

    Full Text:The issue of Teaching physics vs Learning physics in our institutions of higher learning will be discussed. Physics is taught mainly by frontal lectures an old (and proven) method. The great advancements of the Information Age are introduced by exposing the students to vast amounts of computerized information and directing them to numerical problem solving by interacting with the computer. These modern methods have several drawbacks: 1. Students get the impression of easy material acquisition while in fact it becomes superficial. 2. There is little integration of topics that are taught in different courses. 3. Insufficient interest is built among undergraduate students to pursue studies that involve deeper thinking and independent research (namely, studies towards a doctoral degree). Learning physics is a formative process in the education of physicists, natural scientists and engineers. It must be based on discussions and exchange of ideas among the students, since understanding the studied material means being able to explain it to a colleague. Some universities in the US initiated programs of learning physics by creating an environment in which small groups of students are engaged in discussing material, jointly solving problems and jointly conducting simulated experiments. This is done under the supervision of a mentor. Suggestions for implementing this method in Israel will be discussed

    2005-01-01

    This paper discusses and questions the current metadata standards for learning objects from a pedagogical point of view. From a social constructivist approach, the paper discusses how learning objects can support problem based, self-governed learning activities. In order to support this approach......, it is argued that it is necessary to focus on learning activities rather than on learning objects. Further, it is argued that descriptions of learning objectives and learning activities should be separated from learning objects. The paper presents a new conception of learning objects which supports problem...... based, self-governed activities. Further, a new way of thinking pedagogy into learning objects is introduced. It is argued that a lack of pedagogical thinking in learning objects is not solved through pedagogical metadata. Instead, the paper suggests the concept of references as an alternative...

    In this work we propose a new deep learning tool called deep dictionary learning. Multi-level dictionaries are learnt in a greedy fashion, one layer at a time. This requires solving a simple (shallow) dictionary learning problem, the solution to this is well known. We apply the proposed technique on some benchmark deep learning datasets. We compare our results with other deep learning tools like stacked autoencoder and deep belief network; and state of the art supervised dictionary learning t...

    Yin, Haibo; Yang, Yun-an

    2017-05-01

    In this paper, we propose a new transfer learning algorithm for online training. The proposed algorithm, which is called Online Transfer Extreme Learning Machine (OTELM), is based on Online Sequential Extreme Learning Machine (OSELM) while it introduces Semi-Supervised Extreme Learning Machine (SSELM) to transfer knowledge from the source to the target domain. With the manifold regularization, SSELM picks out instances from the source domain that are less relevant to those in the target domain to initialize the online training, so as to improve the classification performance. Experimental results demonstrate that the proposed OTELM can effectively use instances in the source domain to enhance the learning performance.

  1. When does social learning become cultural learning?

    Science.gov (United States)

    Heyes, Cecilia

    2017-03-01

    Developmental research on selective social learning, or 'social learning strategies', is currently a rich source of information about when children copy behaviour, and who they prefer to copy. It also has the potential to tell us when and how human social learning becomes cultural learning; i.e. mediated by psychological mechanisms that are specialized, genetically or culturally, to promote cultural inheritance. However, this review article argues that, to realize its potential, research on the development of selective social learning needs more clearly to distinguish functional from mechanistic explanation; to achieve integration with research on attention and learning in adult humans and 'dumb' animals; and to recognize that psychological mechanisms can be specialized, not only by genetic evolution, but also by associative learning and cultural evolution. © 2015 John Wiley & Sons Ltd.

    Reinforcement learning is a learning paradigm concerned with learning to control a system so as to maximize a numerical performance measure that expresses a long-term objective. What distinguishes reinforcement learning from supervised learning is that only partial feedback is given to the learner about the learner's predictions. Further, the predictions may have long term effects through influencing the future state of the controlled system. Thus, time plays a special role. The goal in reinforcement learning is to develop efficient learning algorithms, as well as to understand the algorithms'

    2015-03-01

    Full Text Available The public health nurses’ scope of practice explicitly includes child protection within their role, which places them in a prime position to identify child protection concerns. This role compliments that of other professions and voluntary agenices who work with children. Public health nurses are in a privileged position as they form a relationship with the child’s parent(s/guardian(s and are able to see the child in its own environment, which many professionals cannot. Child protection in Ireland, while influenced by other countries, has progressed through a distinct pathway that streamlined protocols and procedures. However, despite the above serious failures have occurred in the Irish system, and inquiries over the past 20 years persistently present similar contributing factors, namely, the lack of standardized and comprehensive service responses. Moreover, poor practice is compounded by the lack of recognition of the various interactional processes taking place within and between the different agencies of child protection, leading to psychological barriers in communication. This article will explore the lessons learned for public health nurses practice in safeguarding children in the Republic of Ireland.

  12. Learning tinnitus

    Science.gov (United States)

    van Hemmen, J. Leo

    Tinnitus, implying the perception of sound without the presence of any acoustical stimulus, is a chronic and serious problem for about 2% of the human population. In many cases, tinnitus is a pitch-like sensation associated with a hearing loss that confines the tinnitus frequency to an interval of the tonotopic axis. Even in patients with a normal audiogram the presence of tinnitus may be associated with damage of hair-cell function in this interval. It has been suggested that homeostatic regulation and, hence, increase of activity leads to the emergence of tinnitus. For patients with hearing loss, we present spike-timing-dependent Hebbian plasticity (STDP) in conjunction with homeostasis as a mechanism for ``learning'' tinnitus in a realistic neuronal network with tonotopically arranged synaptic excitation and inhibition. In so doing we use both dynamical scaling of the synaptic strengths and altering the resting potential of the cells. The corresponding simulations are robust to parameter changes. Understanding the mechanisms of tinnitus induction, such as here, may help improving therapy. Work done in collaboration with Julie Goulet and Michael Schneider.

    Kemény, Ferenc; Meier, Beat

    2016-02-01

    While sequence learning research models complex phenomena, previous studies have mostly focused on unimodal sequences. The goal of the current experiment is to put implicit sequence learning into a multimodal context: to test whether it can operate across different modalities. We used the Task Sequence Learning paradigm to test whether sequence learning varies across modalities, and whether participants are able to learn multimodal sequences. Our results show that implicit sequence learning is very similar regardless of the source modality. However, the presence of correlated task and response sequences was required for learning to take place. The experiment provides new evidence for implicit sequence learning of abstract conceptual representations. In general, the results suggest that correlated sequences are necessary for implicit sequence learning to occur. Moreover, they show that elements from different modalities can be automatically integrated into one unitary multimodal sequence. Copyright © 2015 Elsevier B.V. All rights reserved.

    This paper outlines the main infrastructure for implicating mobile learning in medicine and present a sample mobile learning application for medical learning within the framework of mobile learning systems. Mobile technology is developing nowadays. In this case it will be useful to develop different learning environments using these innovations in internet based distance education. M-learning makes the most of being on location, providing immediate access, being connected, and acknowledges learning that occurs beyond formal learning settings, in places such as the workplace, home, and outdoors. Central to m-learning is the principle that it is the learner who is mobile rather than the device used to deliver m learning. The integration of mobile technologies into training has made learning more accessible and portable. Mobile technologies make it possible for a learner to have access to a computer and subsequently learning material and activities; at any time and in any place. Mobile devices can include: mobile phone, personal digital assistants (PDAs), personal digital media players (eg iPods, MP3 players), portable digital media players, portable digital multimedia players. Mobile learning (m-learning) is particularly important in medical education, and the major users of mobile devices are in the field of medicine. The contexts and environment in which learning occurs necessitates m-learning. Medical students are placed in hospital/clinical settings very early in training and require access to course information and to record and reflect on their experiences while on the move. As a result of this paper, this paper strives to compare and contrast mobile learning with normal learning in medicine from various perspectives and give insights and advises into the essential characteristics of both for sustaining medical education.

    LLNL turned in 5 Declaration Line Items (DLI's) in 2006. Of these, one was declared completed. We made some changes to streamline our process from 2005, used less money, time and fewer team members. This report is a description of what changes we made in 2006 and what we learned. Many of our core review team had changed from last year, including our Laboratory Director, the Facility safety and security representatives, our Division Leader, and the OPSEC Committee Chair. We were able to hand out an AP Manual to some of them, and briefed all newcomers to the AP process. We first went to the OPSEC Committee and explained what the Additional Protocol process would be for 2006 and solicited their help in locating declarable projects. We utilized the 'three questions' from the AP meeting last year. LLNL has no single place to locate all projects at the laboratory. We talked to Resource Managers and key Managers in the Energy and Environment Directorate and in the Nonproliferation Homeland and International Security Directorate to find applicable projects. We also talked to the Principal Investigators who had projects last year. We reviewed a list of CRADA's and LDRD projects given to us by the Laboratory Site Office. Talking to the PI's proved difficult because of vacation or travel schedules. We were never able to locate one PI in town. Fortunately, collateral information allowed us to screen out his project. We had no problems in downloading new versions of the DWA and DDA. It was helpful for both Steve Blair and Arden Dougan to have write privileges. During the time we were working on the project, we had to tag-team the work to allow for travel and vacation schedules. We had some difficulty locating an 'activities block' in the software. This was mentioned as something we needed to fix from our 2005 declaration. Evidently the Activities Block has been removed from the current version of the software. We also had trouble finding the DLI Detail Report, which we included

  1. Supervised Learning for Dynamical System Learning.

    Science.gov (United States)

    Hefny, Ahmed; Downey, Carlton; Gordon, Geoffrey J

    2015-01-01

    Recently there has been substantial interest in spectral methods for learning dynamical systems. These methods are popular since they often offer a good tradeoff between computational and statistical efficiency. Unfortunately, they can be difficult to use and extend in practice: e.g., they can make it difficult to incorporate prior information such as sparsity or structure. To address this problem, we present a new view of dynamical system learning: we show how to learn dynamical systems by solving a sequence of ordinary supervised learning problems, thereby allowing users to incorporate prior knowledge via standard techniques such as L 1 regularization. Many existing spectral methods are special cases of this new framework, using linear regression as the supervised learner. We demonstrate the effectiveness of our framework by showing examples where nonlinear regression or lasso let us learn better state representations than plain linear regression does; the correctness of these instances follows directly from our general analysis.

  1. KARATE WITH CONSTRUCTIVE LEARNING

    Directory of Open Access Journals (Sweden)

    Srikrishna Karanam

    2012-02-01

    Full Text Available Any conventional learning process involves the traditional hierarchy of garnering of information and then recall gathered information. Constructive learning is an important research area having wide impact on teaching methods in education, learning theories, and plays a major role in many education reform movements. It is observed that constructive learning advocates the interconnection between emotions and learning. Human teachers identify the emotions of students with varying degrees of accuracy and can improve the learning rate of the students by motivating them. In learning with computers, computers also should be given the capability to recognize emotions so as to optimize the learning process. Image Processing is a very popular tool used in the process of establishing the theory of Constructive Learning. In this paper we use the Optical Flow computation in image sequences to analyze the accuracy of the moves of a karate player. We have used the Lucas-Kanade method for computing the optical flow in image sequences. A database consisting of optical flow images by a group of persons learning karate is formed and the learning rates are analyzed in order to main constructive learning. The contours of flow images are compared with the standard images and the error graphs are plotted. Analysis of the emotion of the amateur karate player is made by observing the error plots.

We find that, keeping memory of his errors, under mild assumptions an acceptable solution is asymptotically reached. Moreover, one can take advantage of big errors for a faster learning.

    2017-09-13

    Fuelled by increasing computer power and algorithmic advances, machine learning techniques have become powerful tools for finding patterns in data. Quantum systems produce atypical patterns that classical systems are thought not to produce efficiently, so it is reasonable to postulate that quantum computers may outperform classical computers on machine learning tasks. The field of quantum machine learning explores how to devise and implement quantum software that could enable machine learning that is faster than that of classical computers. Recent work has produced quantum algorithms that could act as the building blocks of machine learning programs, but the hardware and software challenges are still considerable.

  10. Learning and memory

    Directory of Open Access Journals (Sweden)

    P. A. J. Ryke

    1989-03-01

    Full Text Available Under various circumstances and in different species the outward expression of learning varies considerably, and this has led to the classification of different categories of learning. Just as there is no generally agreed on definition of learning, there is no one system of classification. Types of learning commonly recognized are: Habituation, sensitization, classical conditioning, operant conditioning, trial and error, taste aversion, latent learning, cultural learning, imprinting, insight learning, learning-set learning and instinct. The term memory must include at least two separate processes. It must involve, on the one hand, that of learning something and on the other, at some later date, recalling that thing. What lies between the learning and (he remembering must be some permanent record — a memory trace — within the brain. Memory exists in at least two forms: memory for very recent events (short-term which is relatively labile and easily disruptable; and long-term memory, which is much more stable. Not everything that gets into short-term memory becomes fixed in the long-term store; a filtering mechanism selects things that might be important and discards the rest.

  11. Approximate kernel competitive learning.

    Wu, Jian-Sheng; Zheng, Wei-Shi; Lai, Jian-Huang

    2015-03-01

    Kernel competitive learning has been successfully used to achieve robust clustering. However, kernel competitive learning (KCL) is not scalable for large scale data processing, because (1) it has to calculate and store the full kernel matrix that is too large to be calculated and kept in the memory and (2) it cannot be computed in parallel. In this paper we develop a framework of approximate kernel competitive learning for processing large scale dataset. The proposed framework consists of two parts. First, it derives an approximate kernel competitive learning (AKCL), which learns kernel competitive learning in a subspace via sampling. We provide solid theoretical analysis on why the proposed approximation modelling would work for kernel competitive learning, and furthermore, we show that the computational complexity of AKCL is largely reduced. Second, we propose a pseudo-parallelled approximate kernel competitive learning (PAKCL) based on a set-based kernel competitive learning strategy, which overcomes the obstacle of using parallel programming in kernel competitive learning and significantly accelerates the approximate kernel competitive learning for large scale clustering. The empirical evaluation on publicly available datasets shows that the proposed AKCL and PAKCL can perform comparably as KCL, with a large reduction on computational cost. Also, the proposed methods achieve more effective clustering performance in terms of clustering precision against related approximate clustering approaches. Copyright © 2014 Elsevier Ltd.

    The machine learning field, which can be briefly defined as enabling computers make successful predictions using past experiences, has exhibited an impressive development recently with the help of the rapid increase in the storage capacity and processing power of computers. Together with many other disciplines, machine learning methods have been widely employed in bioinformatics. The difficulties and cost of biological analyses have led to the development of sophisticated machine learning approaches for this application area. In this chapter, we first review the fundamental concepts of machine learning such as feature assessment, unsupervised versus supervised learning and types of classification. Then, we point out the main issues of designing machine learning experiments and their performance evaluation. Finally, we introduce some supervised learning methods.

  16. Semantic Learning Service Personalized

    Directory of Open Access Journals (Sweden)

    2012-02-01

    Full Text Available To provide users with more suitable and personalized service, personalization is widely used in various fields. Current e-Learning systems search for learning resources using information search technology, based on the keywords that selected or inputted by the user. Due to lack of semantic analysis for keywords and exploring the user contexts, the system cannot provide a good learning experiment. In this paper, we defined the concept and characteristic of the personalized learning service, and proposed a semantic learning service personalized framework. Moreover, we made full use of semantic technology, using ontologies to represent the learning contents and user profile, mining and utilizing the friendship and membership of the social relationship to construct the user social relationship profile, and improved the collaboration filtering algorithm to recommend personalized learning resources for users. The results of the empirical evaluation show that the approach is effectiveness in augmenting recommendation.

  17. Infant Statistical Learning

    Science.gov (United States)

    Saffran, Jenny R.; Kirkham, Natasha Z.

    2017-01-01

    Perception involves making sense of a dynamic, multimodal environment. In the absence of mechanisms capable of exploiting the statistical patterns in the natural world, infants would face an insurmountable computational problem. Infant statistical learning mechanisms facilitate the detection of structure. These abilities allow the infant to compute across elements in their environmental input, extracting patterns for further processing and subsequent learning. In this selective review, we summarize findings that show that statistical learning is both a broad and flexible mechanism (supporting learning from different modalities across many different content areas) and input specific (shifting computations depending on the type of input and goal of learning). We suggest that statistical learning not only provides a framework for studying language development and object knowledge in constrained laboratory settings, but also allows researchers to tackle real-world problems, such as multilingualism, the role of ever-changing learning environments, and differential developmental trajectories.

    The paper explores the contribution of Communities of Practice (COP) to Human Resource Development (HRD). Learning as negotiating identities captures the contribution of COP to HRD. In COP the development of practice happens through negotiation of meaning. The learning process also involves modes...... of belonging constitutive of our identities. We suggest that COP makes a significant contribution by linking learning and identification. This means that learning becomes much less instrumental and much more linked to fundamental questions of being. We argue that the COP-framework links learning with the issue...... of time - caught in the notion of trajectories of learning - that integrate past, present and future. Working with the learners' notion of time is significant because it is here that new learning possibilities become visible and meaningful for individuals. Further, we argue that the concept of identity...

  10. Learning from neural control.

    Science.gov (United States)

    Wang, Cong; Hill, David J

    2006-01-01

    One of the amazing successes of biological systems is their ability to "learn by doing" and so adapt to their environment. In this paper, first, a deterministic learning mechanism is presented, by which an appropriately designed adaptive neural controller is capable of learning closed-loop system dynamics during tracking control to a periodic reference orbit. Among various neural network (NN) architectures, the localized radial basis function (RBF) network is employed. A property of persistence of excitation (PE) for RBF networks is established, and a partial PE condition of closed-loop signals, i.e., the PE condition of a regression subvector constructed out of the RBFs along a periodic state trajectory, is proven to be satisfied. Accurate NN approximation for closed-loop system dynamics is achieved in a local region along the periodic state trajectory, and a learning ability is implemented during a closed-loop feedback control process. Second, based on the deterministic learning mechanism, a neural learning control scheme is proposed which can effectively recall and reuse the learned knowledge to achieve closed-loop stability and improved control performance. The significance of this paper is that the presented deterministic learning mechanism and the neural learning control scheme provide elementary components toward the development of a biologically-plausible learning and control methodology. Simulation studies are included to demonstrate the effectiveness of the approach.

  19. Deep learning: Using machine learning to study biological vision

    OpenAIRE

    Majaj, Najib; Pelli, Denis

    2017-01-01

    Today most vision-science presentations mention machine learning. Many neuroscientists use machine learning to decode neural responses. Many perception scientists try to understand recognition by living organisms. To them, machine learning offers a reference of attainable performance based on learned stimuli. This brief overview of the use of machine learning in biological vision touches on its strengths, weaknesses, milestones, controversies, and current directions.

  1. Cultural dimensions of learning

    Science.gov (United States)

    Eyford, Glen A.

    1990-06-01

    How, what, when and where we learn is frequently discussed, as are content versus process, or right brain versus left brain learning. What is usually missing is the cultural dimension. This is not an easy concept to define, but various aspects can be identified. The World Decade for Cultural Development emphasizes the need for a counterbalance to a quantitative, economic approach. In the last century poets also warned against brutalizing materialism, and Sorokin and others have described culture more recently in terms of cohesive basic values expressed through aesthetics and institutions. Bloom's taxonomy incorporates the category of affective learning, which internalizes values. If cultural learning goes beyond knowledge acquisition, perhaps the surest way of understanding the cultural dimension of learning is to examine the aesthetic experience. This can use myths, metaphors and symbols, and to teach and learn by using these can help to unlock the human potential for vision and creativity.

    Science.gov (United States)

    Tomasello, Michael

    2016-05-01

    M. Tomasello, A. Kruger, and H. Ratner (1993) proposed a theory of cultural learning comprising imitative learning, instructed learning, and collaborative learning. Empirical and theoretical advances in the past 20 years suggest modifications to the theory; for example, children do not just imitate but overimitate in order to identify and affiliate with others in their cultural group, children learn from pedagogy not just episodic facts but the generic structure of their cultural worlds, and children collaboratively co-construct with those in their culture normative rules for doing things. In all, human children do not just culturally learn useful instrumental activities and information, they conform to the normative expectations of the cultural group and even contribute themselves to the creation of such normative expectations. © 2016 The Author.

  6. Learning efficient correlated equilibria

    KAUST Repository

    Borowski, Holly P.; Marden, Jason R.; Shamma, Jeff S.

    2014-01-01

    The majority of distributed learning literature focuses on convergence to Nash equilibria. Correlated equilibria, on the other hand, can often characterize more efficient collective behavior than even the best Nash equilibrium. However, there are no existing distributed learning algorithms that converge to specific correlated equilibria. In this paper, we provide one such algorithm which guarantees that the agents' collective joint strategy will constitute an efficient correlated equilibrium with high probability. The key to attaining efficient correlated behavior through distributed learning involves incorporating a common random signal into the learning environment.

  16. What is Social Learning?

    Mark S. Reed

    2010-12-01

    between individual and wider social learning. Many unsubstantiated claims for social learning exist, and there is frequently confusion between the concept itself and its potential outcomes. This lack of conceptual clarity has limited our capacity to assess whether social learning has occurred, and if so, what kind of learning has taken place, to what extent, between whom, when, and how. This response attempts to provide greater clarity on the conceptual basis for social learning. We argue that to be considered social learning, a process must: (1 demonstrate that a change in understanding has taken place in the individuals involved; (2 demonstrate that this change goes beyond the individual and becomes situated within wider social units or communities of practice; and (3 occur through social interactions and processes between actors within a social network. A clearer picture of what we mean by social learning could enhance our ability to critically evaluate outcomes and better understand the processes through which social learning occurs. In this way, it may be possible to better facilitate the desired outcomes of social learning processes.

    2018-04-01

    This paper introduces a novel manifold regularized reinforcement learning scheme for continuous Markov decision processes. Smooth feature representations for value function approximation can be automatically learned using the unsupervised manifold regularization method. The learned features are data-driven, and can be adapted to the geometry of the state space. Furthermore, the scheme provides a direct basis representation extension for novel samples during policy learning and control. The performance of the proposed scheme is evaluated on two benchmark control tasks, i.e., the inverted pendulum and the energy storage problem. Simulation results illustrate the concepts of the proposed scheme and show that it can obtain excellent performance.

    Directory of Open Access Journals (Sweden)

    2013-04-01

    Full Text Available If a few decades ago, the education received in school could be in most of the cases enough to go with for the rest of one’s entire life, today the situation has changed dramatically. The individual has to be prepared for a new type of life and training, namely lifelong learning. The individual’s survival in society could depend on his capacity to learn, to re-qualify, to forget what he once learned and to train for the future in an entirely different manner. Within this context, e-learning and distance education can be viable alternatives for the necessary and imperative adaptation process. Modern man’s education has to go beyond the stage of level oriented education (limited in terms of trainee number and training duration and advance towards continuous education, which is able to train the individual irrespective of his location and with no limitations in terms of time. The passage towards the information society involves mutations in the object of the activities, mainly in terms of selecting, storing, preserving, managing and protecting information. Against this extremely fluctuant background, a relevant question rises: is the adult capable of coping, both individually and socially, with the challenge of e-learning?

  5. Learning environment, learning styles and conceptual understanding

    Science.gov (United States)

    Ferrer, Lourdes M.

    1990-01-01

    In recent years there have been many studies on learners developing conceptions of natural phenomena. However, so far there have been few attempts to investigate how the characteristics of the learners and their environment influence such conceptions. This study began with an attempt to use an instrument developed by McCarthy (1981) to describe learners in Malaysian primary schools. This proved inappropriate as Asian primary classrooms do not provide the same kind of environment as US classrooms. It was decided to develop a learning style checklist to suit the local context and which could be used to describe differences between learners which teachers could appreciate and use. The checklist included four dimensions — perceptual, process, self-confidence and motivation. The validated instrument was used to determine the learning style preferences of primary four pupils in Penang, Malaysia. Later, an analysis was made regarding the influence of learning environment and learning styles on conceptual understanding in the topics of food, respiration and excretion. This study was replicated in the Philippines with the purpose of investigating the relationship between learning styles and achievement in science, where the topics of food, respiration and excretion have been taken up. A number of significant relationships were observed in these two studies.

  7. Learning Curve? Which One?

    Directory of Open Access Journals (Sweden)

    Paulo Prochno

    2004-07-01

    Full Text Available Learning curves have been studied for a long time. These studies provided strong support to the hypothesis that, as organizations produce more of a product, unit costs of production decrease at a decreasing rate (see Argote, 1999 for a comprehensive review of learning curve studies. But the organizational mechanisms that lead to these results are still underexplored. We know some drivers of learning curves (ADLER; CLARK, 1991; LAPRE et al., 2000, but we still lack a more detailed view of the organizational processes behind those curves. Through an ethnographic study, I bring a comprehensive account of the first year of operations of a new automotive plant, describing what was taking place on in the assembly area during the most relevant shifts of the learning curve. The emphasis is then on how learning occurs in that setting. My analysis suggests that the overall learning curve is in fact the result of an integration process that puts together several individual ongoing learning curves in different areas throughout the organization. In the end, I propose a model to understand the evolution of these learning processes and their supporting organizational mechanisms.

    Deo, Rahul C

    2015-11-17

    Spurred by advances in processing power, memory, storage, and an unprecedented wealth of data, computers are being asked to tackle increasingly complex learning tasks, often with astonishing success. Computers have now mastered a popular variant of poker, learned the laws of physics from experimental data, and become experts in video games - tasks that would have been deemed impossible not too long ago. In parallel, the number of companies centered on applying complex data analysis to varying industries has exploded, and it is thus unsurprising that some analytic companies are turning attention to problems in health care. The purpose of this review is to explore what problems in medicine might benefit from such learning approaches and use examples from the literature to introduce basic concepts in machine learning. It is important to note that seemingly large enough medical data sets and adequate learning algorithms have been available for many decades, and yet, although there are thousands of papers applying machine learning algorithms to medical data, very few have contributed meaningfully to clinical care. This lack of impact stands in stark contrast to the enormous relevance of machine learning to many other industries. Thus, part of my effort will be to identify what obstacles there may be to changing the practice of medicine through statistical learning approaches, and discuss how these might be overcome. © 2015 American Heart Association, Inc.

  5. Robots Learn Writing

    Directory of Open Access Journals (Sweden)

    Huan Tan

    2012-01-01

    Full Text Available This paper proposes a general method for robots to learn motions and corresponding semantic knowledge simultaneously. A modified ISOMAP algorithm is used to convert the sampled 6D vectors of joint angles into 2D trajectories, and the required movements for writing numbers are learned from this modified ISOMAP-based model. Using this algorithm, the knowledge models are established. Learned motion and knowledge models are stored in a 2D latent space. Gaussian Process (GP method is used to model and represent these models. Practical experiments are carried out on a humanoid robot, named ISAC, to learn the semantic representations of numbers and the movements of writing numbers through imitation and to verify the effectiveness of this framework. This framework is applied into training a humanoid robot, named ISAC. At the learning stage, ISAC not only learns the dynamics of the movement required to write the numbers, but also learns the semantic meaning of the numbers which are related to the writing movements from the same data set. Given speech commands, ISAC recognizes the words and generated corresponding motion trajectories to write the numbers. This imitation learning method is implemented on a cognitive architecture to provide robust cognitive information processing.

    Full Text Available The paper explains the evolution of e-Learning and related concepts and tools and its connection with other concepts such as Knowledge Management, Human Resources Management, Enterprise Resource Planning, and Information Technology. The paper also distinguished Learning Content Management Systems from Learning Management Systems and Content Management Systems used for general web-based content. The newest Learning Content Management System, very expensive and yet very little implemented is one of the best tools that helps us to cope with the realities of the 21st Century in what learning concerns. The debates over how beneficial one or another system is for an organization, can be driven by costs involved, efficiency envisaged, and availability of the product on the market.

  11. Learning During Stressful Times

    Shors, Tracey J.

    2012-01-01

    Stressful life events can have profound effects on our cognitive and motor abilities, from those that could be construed as adaptive to those not so. In this review, I discuss the general notion that acute stressful experience necessarily impairs our abilities to learn and remember. The effects of stress on operant conditioning, that is, learned helplessness, as well as those on classical conditioning procedures are discussed in the context of performance and adaptation. Studies indicating sex differences in learning during stressful times are discussed, as are those attributing different responses to the existence of multiple memory systems and nonlinear relationships. The intent of this review is to highlight the apparent plasticity of the stress response, how it might have evolved to affect both performance and learning processes, and the potential problems with interpreting stress effects on learning as either good or bad. An appreciation for its plasticity may provide new avenues for investigating its underlying neuronal mechanisms. PMID:15054128

    Deep learning is a form of machine learning using a convolutional neural network architecture that shows tremendous promise for imaging applications. It is increasingly being adapted from its original demonstration in computer vision applications to medical imaging. Because of the high volume and wealth of multimodal imaging information acquired in typical studies, neuroradiology is poised to be an early adopter of deep learning. Compelling deep learning research applications have been demonstrated, and their use is likely to grow rapidly. This review article describes the reasons, outlines the basic methods used to train and test deep learning models, and presents a brief overview of current and potential clinical applications with an emphasis on how they are likely to change future neuroradiology practice. Facility with these methods among neuroimaging researchers and clinicians will be important to channel and harness the vast potential of this new method. © 2018 by American Journal of Neuroradiology.

  14. Varieties of perceptual learning.

    Mackintosh, N J

    2009-05-01

    Although most studies of perceptual learning in human participants have concentrated on the changes in perception assumed to be occurring, studies of nonhuman animals necessarily measure discrimination learning and generalization and remain agnostic on the question of whether changes in behavior reflect changes in perception. On the other hand, animal studies do make it easier to draw a distinction between supervised and unsupervised learning. Differential reinforcement will surely teach animals to attend to some features of a stimulus array rather than to others. But it is an open question as to whether such changes in attention underlie the enhanced discrimination seen after unreinforced exposure to such an array. I argue that most instances of unsupervised perceptual learning observed in animals (and at least some in human animals) are better explained by appeal to well-established principles and phenomena of associative learning theory: excitatory and inhibitory associations between stimulus elements, latent inhibition, and habituation.

  20. Circuit mechanisms of sensorimotor learning

    2016-01-01

    SUMMARY The relationship between the brain and the environment is flexible, forming the foundation for our ability to learn. Here we review the current state of our understanding of the modifications in the sensorimotor pathway related to sensorimotor learning. We divide the process in three hierarchical levels with distinct goals: 1) sensory perceptual learning, 2) sensorimotor associative learning, and 3) motor skill learning. Perceptual learning optimizes the representations of important sensory stimuli. Associative learning and the initial phase of motor skill learning are ensured by feedback-based mechanisms that permit trial-and-error learning. The later phase of motor skill learning may primarily involve feedback-independent mechanisms operating under the classic Hebbian rule. With these changes under distinct constraints and mechanisms, sensorimotor learning establishes dedicated circuitry for the reproduction of stereotyped neural activity patterns and behavior.

  1. Transfer Learning beyond Text Classification

    Science.gov (United States)

    Yang, Qiang

    Transfer learning is a new machine learning and data mining framework that allows the training and test data to come from different distributions or feature spaces. We can find many novel applications of machine learning and data mining where transfer learning is necessary. While much has been done in transfer learning in text classification and reinforcement learning, there has been a lack of documented success stories of novel applications of transfer learning in other areas. In this invited article, I will argue that transfer learning is in fact quite ubiquitous in many real world applications. In this article, I will illustrate this point through an overview of a broad spectrum of applications of transfer learning that range from collaborative filtering to sensor based location estimation and logical action model learning for AI planning. I will also discuss some potential future directions of transfer learning.

    Moreton, Elliott; Pater, Joe; Pertsova, Katya

    2017-01-01

    Linguistic and non-linguistic pattern learning have been studied separately, but we argue for a comparative approach. Analogous inductive problems arise in phonological and visual pattern learning. Evidence from three experiments shows that human learners can solve them in analogous ways, and that human performance in both cases can be captured by the same models. We test GMECCS (Gradual Maximum Entropy with a Conjunctive Constraint Schema), an implementation of the Configural Cue Model (Gluck & Bower, ) in a Maximum Entropy phonotactic-learning framework (Goldwater & Johnson, ; Hayes & Wilson, ) with a single free parameter, against the alternative hypothesis that learners seek featurally simple algebraic rules ("rule-seeking"). We study the full typology of patterns introduced by Shepard, Hovland, and Jenkins () ("SHJ"), instantiated as both phonotactic patterns and visual analogs, using unsupervised training. Unlike SHJ, Experiments 1 and 2 found that both phonotactic and visual patterns that depended on fewer features could be more difficult than those that depended on more features, as predicted by GMECCS but not by rule-seeking. GMECCS also correctly predicted performance differences between stimulus subclasses within each pattern. A third experiment tried supervised training (which can facilitate rule-seeking in visual learning) to elicit simple rule-seeking phonotactic learning, but cue-based behavior persisted. We conclude that similar cue-based cognitive processes are available for phonological and visual concept learning, and hence that studying either kind of learning can lead to significant insights about the other.

    In a basic associative learning paradigm, learning is said to have occurred when the conditioned stimulus evokes an anticipatory response. This learning is widely believed to depend on the contiguous presentation of conditioned and unconditioned stimulus. However, what it means to be contiguous has not been rigorously defined. Here we examine the empirical bases for these beliefs and suggest an alternative view based on the hypothesis that learning about the temporal relationships between events determines the speed of emergence, vigor and form of conditioned behavior. This temporal learning occurs very rapidly and prior to the appearance of the anticipatory response. The temporal relations are learned even when no anticipatory response is evoked. The speed with which an anticipatory response emerges is proportional to the informativeness of the predictive cue (CS) regarding the rate of occurrence of the predicted event (US). This analysis gives an account of what we mean by "temporal pairing" and is in accord with the data on speed of acquisition and basic findings in the cue competition literature. In this account, learning depends on perceiving and encoding temporal regularities rather than stimulus contiguities.

  5. Mobile and contextual learning

    2009-12-01

    Full Text Available Is mobile learning just a part of everyday learning? This is a relevant question in an age when most people throughout the world now have access to mobile phones and mobility is increasingly taken for granted. In one sense, mobile learning is no different to carrying a textbook or learning through conversations at home, as part of formal education or in the workplace. The technology may be more engaging, but is the learning any different? Despite the ubiquity of mobile phones, smartphones, mp3 players and, increasingly, access to Wi-Fi connections and GPS navigation, the reasons for using mobile and wireless technologies in education are not yet widely known. There is significant specialist expertise, built from ten years of research (and more recently, reflective practice to demonstrate the unique characteristics of mobile learning, which include orchestrating shared learning with personal devices across formal and informal settings, providing immediately useful information, offering timely revision and reflection, connecting real and virtual locations, and enriching field trips and cultural visits. This knowledge needs to be disseminated and examined from new perspectives.

    2012-01-01

    In this paper, we give a short introduction to machine learning and survey its applications in radiology. We focused on six categories of applications in radiology: medical image segmentation, registration, computer aided detection and diagnosis, brain function or activity analysis and neurological disease diagnosis from fMR images, content-based image retrieval systems for CT or MRI images, and text analysis of radiology reports using natural language processing (NLP) and natural language understanding (NLU). This survey shows that machine learning plays a key role in many radiology applications. Machine learning identifies complex patterns automatically and helps radiologists make intelligent decisions on radiology data such as conventional radiographs, CT, MRI, and PET images and radiology reports. In many applications, the performance of machine learning-based automatic detection and diagnosis systems has shown to be comparable to that of a well-trained and experienced radiologist. Technology development in machine learning and radiology will benefit from each other in the long run. Key contributions and common characteristics of machine learning techniques in radiology are discussed. We also discuss the problem of translating machine learning applications to the radiology clinical setting, including advantages and potential barriers. PMID:22465077

    2016-03-01

    Nursing students have difficulty with pharmacology courses because of the complicated nomenclature and the difficulty of applying drug information to actual patient care. As part of a new pharmacology course being created, meta-learning strategies designed to diminish the difficulties of learning this difficult content were part of the course pedagogy. Strategies were demonstrated, reviewed in class, and implemented through homework assignments. The setting was an Academic Health Center's School of Nursing in the southern United States. Participants were third-year nursing students in an undergraduate nursing program. Surveys of students' opinions of learning gains were conducted at the end of the course over several semesters. In addition, pharmacology scores on a standardized exit exam were compared prior to implementing the course and after. Students reported learning dry material more easily, having greater confidence, and finding substantial value in the learning strategies. Students indicated the most helpful strategies, in descending order, as follows: making charts to compare and contrast drugs and drug classes, writing out drug flash cards, making or reviewing creative projects, prioritizing information, making or using visual study aids, and using time and repetition to space learning. Implementation of the new course improved pharmacology scores on a standardized exit exam from 67.0% to 74.3%. Overall response to learning strategies was positive, and the increase in the pharmacology standardized exit exam scores demonstrated the effectiveness of this instructional approach.
