Potential source regions and processes of aerosol in the summer Arctic
Authors: Heintzenberg J. , Leck C. , Tunved P.
Published: June 2015

Abstract. Sub-micrometer particle size distributions measured during four summer cruises of the Swedish icebreaker Oden 1991, 1996, 2001, and 2008 were combined with dimethyl sulfide gas data, back trajectories, and daily maps of pack ice cover in order to investigate source areas and aerosol formation processes of the boundary layer aerosol in the central Arctic. With a clustering algorithm, potential aerosol source areas were explored. Clustering of particle size distributions together with back trajectories delineated five potential source regions and three different aerosol types that covered most of the Arctic Basin: marine, newly formed and aged particles over the pack ice. Most of the pack ice area with < 15% of open water under the trajectories exhibited the aged aerosol type with only one major mode around 40 nm. For newly formed particles to occur, two conditions had to be fulfilled over the pack ice: the air had spent 10 days while traveling over ever more contiguous ice and had traveled over less than 30% open water during the last 5 days. Additionally, the air had experienced more open water (at least twice as much as in the cases of aged aerosol) during the last 4 days before arrival in heavy ice conditions at Oden. Thus we hypothesize that these two conditions were essential factors for the formation of ultrafine particles over the central Arctic pack ice. In a comparison the Oden data with summer size distribution data from Alert, Nunavut, and Mt. Zeppelin, Spitsbergen, we confirmed the Oden findings with respect to particle sources over the central Arctic. Future more frequent broken-ice or open water patches in summer will spur biological activity in surface water promoting the formation of biological particles. Thereby low clouds and fogs and subsequently the surface energy balance and ice melt may be affected.
Regional differences in Chinese SO2 emission control efficiency and policy implications

Published: June 2015

Abstract. SO2 emission control has been one of the most important air pollution policies in China since 2000. In this study, we assess regional differences in SO2 emission control efficiencies in China through the modeling analysis of four scenarios of SO2 emissions, all of which aim to reduce the national total SO2 emissions by 8% or 2.3 Tg below the 2010 emissions level, the target set by the current twelfth Five-Year Plan (FYP; 2011–2015), but differ in spatial implementation. The GEOS-Chem chemical transport model is used to evaluate the efficiency of each scenario on the basis of four impact metrics: surface SO2 and sulfate concentrations, population-weighted sulfate concentration (PWC), and sulfur export flux from China to the western Pacific. The efficiency of SO2 control (β) is defined as the relative change of each impact metric to a 1% reduction in SO2 emissions from the 2010 baseline. The S1 scenario, which adopts a spatially uniform reduction in SO2 emissions in China, gives a β of 0.99, 0.71, 0.83, and 0.67 for SO2 and sulfate concentrations, PWC, and export flux, respectively. By comparison, the S2 scenario, which implements all the SO2 emissions reduction over North China (NC), is found most effective in reducing national mean surface SO2 and sulfate concentrations and sulfur export fluxes, with β being 1.0, 0.76, and 0.95 respectively. The S3 scenario of implementing all the SO2 emission reduction over South China (SC) has the highest β in reducing PWC (β = 0.98) because SC has the highest correlation between population density and sulfate concentration. Reducing SO2 emissions over Southwest China (SWC) is found to be least efficient on the national scale, albeit with large benefits within the region. The difference in β by scenario is attributable to the regional difference in SO2 oxidation pathways and the source–receptor relationship. Among the three regions examined here, NC shows the largest proportion of sulfate formation through gas-phase oxidation, which is more sensitive to SO2 emissions change than aqueous oxidation. In addition, NC makes the largest contribution to inter-regional transport of sulfur within China and to the transport fluxes to the western Pacific. The policy implication of this is that China needs to carefully design a regionally specific implementation plan of realizing its SO2 emissions reduction target in order to maximize the resulting air quality benefits, not only for China but for the downwind regions, with emphasis on reducing emissions from NC, where SO2 emissions have decreased at a slower rate than national total emissions in the previous FYP period.
Modelling the impact of climate change on the atmospheric transport and the fate of persistent organic pollutants in the Arctic

Published: June 2015

Abstract. The Danish Eulerian Hemispheric Model (DEHM) was applied to investigate how projected climate changes will affect the atmospheric transport of 13 persistent organic pollutants (POPs) to the Arctic and their environmental fate within the Arctic. Three sets of simulations were performed, one with present day emissions and initial environmental concentrations from a 20-year spin-up simulation, one with present day emissions and with initial environmental concentrations set to zero and one without emissions but with initial environmental concentrations from the 20-year spin-up simulation. Each set of simulations consisted of two 10-year time slices representing the present (1990–2000) and future (2090–2100) climate conditions. DEHM was driven using meteorological input from the global circulation model, ECHAM/MPI-OM, simulating the SRES (Special Report on Emissions Scenarios) A1B climate scenario. Under the applied climate and emission scenarios, the total mass of all compounds was predicted to be up to 55 % lower across the Northern Hemisphere at the end of the 2090s than in the 1990s. The mass of HCHs within the Arctic was predicted to be up to 38 % higher, whereas the change in mass of the PCBs was predicted to range from 38 % lower to 17 % higher depending on the congener and the applied initial environmental concentrations. The results of this study also indicate that contaminants with no or a short emission history will be more rapidly transported to and build up in the arctic environment in a future warmer climate. The process that dominates the environmental behaviour of POPs in the Arctic under a future warmer climate scenario is the shift in mass of POPs from the surface media to the atmosphere induced by the higher mean temperature. This is to some degree counteracted by higher degradation rates also following the higher mean temperature. The more dominant of these two processes depends on the physical-chemical properties of the compounds. Previous model studies have predicted that the effect of a changed climate on the transport of POPs to the Arctic is moderate relative to the effect of proposed changes in emissions, which is confirmed in this study. However, the model studies do not agree on whether climate change acts to reduce or increase environmental concentrations of POPs in the Arctic, and further work is needed to resolve this matter.

Abstract. Intense rainfall generated by convective clouds causes flash flooding in many parts of the world. Understanding the microphysical processes leading to the formation of precipitation is one of the main challenges to improving our capability to make quantitative precipitation forecasts. Here, we present microphysics observations of cumulus clouds measured over the Southwest Peninsula of the UK during the COnvective Precipitation Experiment (COPE) in August 2013, which are framed into a wider context using ground-based and airborne radar measurements. Two lines of cumulus clouds formed in the early afternoon along convergence lines aligned with the peninsula. The lines became longer and broader during the afternoon as a result of new cell formation and stratiform regions forming downwind of the convective cells. Aircraft penetrations at −5 °C showed that all the required conditions of the Hallett–Mossop (H–M) ice multiplication process were met in developing regions, and ice concentrations up to 350 L−1 were measured in the mature stratiform regions, indicating that secondary ice production was active. Detailed sampling focused on an isolated liquid cloud that glaciated as it matured to merge with a band of cloud downwind. In the initial cell, a few drizzle drops were measured, some of which froze to form graupel; the ice images are most consistent with freezing drizzle, rather than smaller cloud drops forming the first ice. As new cells developed in and around the cloud, ice concentrations up to two orders of magnitude higher than the predicted ice nuclei concentrations began to be observed and the cloud glaciated over a period of 12–15 min. Ice splinters were captured by supercooled drizzle drops causing them to freeze to form instant-rimers. Graupel and columns were observed in cloud penetrations up to the −12 °C level, though many ice particles were mixed-habit due to riming and growth by vapour diffusion at multiple temperatures. Frozen drizzle/raindrops initially made up the majority of precipitation-sized particles in the H–M zone, while ice splinters required time to grow by vapour diffusion. It is therefore clear that the freezing of supercooled drizzle drops not only provides a pathway to advance the onset of the H–M process, it also accelerates glaciation and the formation of precipitation once it has begun. Accurate representation of both the warm rain and H–M processes, including their interactions with each other and cloud dynamics, appears key to determining the timing and location of precipitation.
Fossil invertebrates records in cave sediments and paleoenvironmental assessments: a study of four cave sites from Romanian Carpathians

Published: June 2015

Abstract. Fossil invertebrates from cave sediments have been recently described as a potential new proxy for paleoenvironment and used in cross-correlations with alternate proxy records from cave deposits. Here we present the results of a fossil invertebrates study in four caves from two climatically different regions of the Romanian Carpathians, to complement paleoenvironmental data previously reported. Oribatid mites and ostracods are the most common invertebrates in the studied cave sediments. Some of the identified taxa are new for science, and most of them are indicative for either warm/cold stages or dry/wetter oscillations. In two caves the fossil invertebrates records indicate rapid climate oscillations during times known for a relatively stable climate. By corroborating the fossil invertebrates' record with the information given by magnetic properties and sediment structures, complementary data on past vegetation, temperatures, and hydraulic regimes could be gathered. This paper analyses the potential of fossil invertebrate records as a paleoenvironmental proxy, potential problems and pitfalls.
The first records of deep-sea fauna – a correction and discussion
Authors: Etter W. , Hess H.
Published: June 2015

Abstract. The soundings in deep waters of Baffin Bay, together with the recovery of a basket star by John Ross in 1818, was a milestone in the history of deep-sea research. Although the alleged water depths of up to 1950 m were by far not reached, these were nevertheless the first soundings in deep bathyal (to perhaps uppermost abyssal) depths. Furthermore, the recovery of a benthic animal proved that animal life existed at great depths. Yet this was not the first published record of deep-sea fauna as it is often portrayed. This merit goes to accidental catches of the stalked crinoid Cenocrinus asterius that were recovered with fishing lines from upper bathyal environments near Antillean islands. In addition, the description of several deep-sea fishes considerably predated the John Ross episode.

Abstract. We explore cropland management alternatives and the effect these can have on future C and N pools and fluxes using the land use-enabled dynamic vegetation model LPJ-GUESS. Simulated crop production, cropland carbon storage, carbon sequestration and nitrogen leaching from croplands are evaluated and discussed. Compared to the version of LPJ-GUESS that does not include land use dynamics, estimates of soil carbon stocks and nitrogen leaching from terrestrial to aquatic ecosystems were improved. We explore trade-offs between important ecosystem services that can be provided from agricultural fields such as crop yields, retention of nitrogen and carbon storage. These trade-offs are evaluated for current land use and climate and further explored for future conditions within the two future climate change scenarios, RCP 2.6 and 8.5. Our results show that the potential for carbon sequestration due to typical cropland management practices such as no-till and cover-crops proposed in literature is not realised, globally or over larger climatic regions. Our results highlight important considerations to be made when modelling C–N interactions in agricultural ecosystems under future environmental change, and the effects these have on terrestrial biogeochemical cycles.
Building long-term and high spatio-temporal resolution precipitation and air temperature reanalyses by mixing local observations and global atmospheric reanalyses: the ANATEM model
Authors: Kuentz A. , Mathevet T. , Gailhard J. , Hingray B.
Published: June 2015

Abstract. Efforts to improve the understanding of past climatic or hydrologic variability have received a great deal of attention in various fields of geosciences such as glaciology, dendrochronology, sedimentology and hydrology. Based on different proxies, each research community produces different kinds of climatic or hydrologic reanalyses at different spatio-temporal scales and resolutions. When considering climate or hydrology, many studies have been devoted to characterising variability, trends or breaks using observed time series representing different regions or climates of the world. However, in hydrology, these studies have usually been limited to short temporal scales (mainly a few decades and more rarely a century) because they require observed time series (which suffer from a limited spatio-temporal density). This paper introduces ANATEM, a method that combines local observations and large-scale climatic information (such as the 20CR Reanalysis) to build long-term probabilistic air temperature and precipitation time series with a high spatio-temporal resolution (1 day and a few km2). ANATEM was tested on the reconstruction of air temperature and precipitation time series of 22 watersheds situated in the Durance River basin, in the French Alps. Based on a multi-criteria and multi-scale diagnosis, the results show that ANATEM improves the performance of classical statistical models – especially concerning spatial homogeneity – while providing an original representation of uncertainties which are conditioned by atmospheric circulation patterns. The ANATEM model has been also evaluated for the regional scale against independent long-term time series and was able to capture regional low-frequency variability over more than a century (1883–2010).
Large-basin hydrological response to climate model outputs: uncertainty caused by internal atmospheric variability

Published: June 2015

Abstract. An approach is proposed to assess hydrological simulation uncertainty originating from internal atmospheric variability. The latter is one of three major factors contributing to uncertainty of simulated climate change projections (along with so-called "forcing" and "climate model" uncertainties). Importantly, the role of internal atmospheric variability is most visible over spatio-temporal scales of water management in large river basins. Internal atmospheric variability is represented by large ensemble simulations (45 members) with the ECHAM5 atmospheric general circulation model. Ensemble simulations are performed using identical prescribed lower boundary conditions (observed sea surface temperature, SST, and sea ice concentration, SIC, for 1979–2012) and constant external forcing parameters but different initial conditions of the atmosphere. The ensemble of bias-corrected ECHAM5 outputs and ensemble averaged ECHAM5 output are used as a distributed input for the ECOMAG and SWAP hydrological models. The corresponding ensembles of runoff hydrographs are calculated for two large rivers of the Arctic basin: the Lena and Northern Dvina rivers. A number of runoff statistics including the mean and the standard deviation of annual, monthly and daily runoff, as well as annual runoff trend, are assessed. Uncertainties of runoff statistics caused by internal atmospheric variability are estimated. It is found that uncertainty of the mean and the standard deviation of runoff has a significant seasonal dependence on the maximum during the periods of spring–summer snowmelt and summer–autumn rainfall floods. Noticeable nonlinearity of the hydrological models' results in the ensemble ECHAM5 output is found most strongly expressed for the Northern Dvina River basin. It is shown that the averaging over ensemble members effectively filters the stochastic term related to internal atmospheric variability. Simulated discharge trends are close to normally distributed around the ensemble mean value, which fits well to empirical estimates and, for the Lena River, indicates that a considerable portion of the observed trend can be externally driven.
Generous to a Fault: A Deep, Recapitulative Pattern of Thought in Ricoeur’s Works
Authors: Schmidt Joél Z.
Published: June 2015

Paul Ricoeur clearly sought to differentiate between and keep separate his philosophical and theological intellectual endeavors. This essay brings into relief a deep, implicit, recapitulative pattern in Ricoeur’s thinking that cuts across this explicit “conceptual asceticism.” Specifically, it highlights this recapitulative pattern in Ricoeur’s treatment of prophecy in the Hebrew Bible; his understanding of utopia and ideology; the functioning of symbols in The Symbolism of Evil and of sublimation in Freud and Philosophy. On these topics Ricoeur extended his typical generosity toward all that might appear to be outdated, primitive, and even regressive in our collective and personal humanity. The frequently recapitulative nature of Ricoeur’s insights indicates the importance not just of the content of his thought but also the way in which he did his thinking, a pattern which above all was generous, even to a fault.
L'imagination poético-pratique dans l'identité narrative
Authors: Amalric Jean-Luc
Published: June 2015

A partir d'une genèse du concept d'identité narrative, cet article s'efforce d'interpréter le processus de constitution de nos identités narratives en prenant appui sur une reprise systématique et synthétique des principaux apports de la théorie ricœurienne de l'imagination depuis la Philosophie de la volonté jusqu’à Soi-même comme une autre. Dans sa constitution imaginative complexe, l’identité narrative peut alors être caractérisée comme un mixte poético-pratique qui médiatise et dialectise deux fonctions distinctes de l’imagination: l’une poétique et l’autre pratique, qui sont elles-mêmes dynamisées par une dialectique et un dédoublement internes.
Paul Ricœur and the Relationship Between Philosophy and Religion in Contemporary French Phenomenology
Authors: Gschwandtner Christina M.
Published: June 2015

In this paper I consider Ricœur’s negotiation of the boundary or relationship between philosophy and religion in light of the larger debate in contemporary French philosophy. I suggest that contrasting his way of dealing with the intersection of the two discourses to that of two other French thinkers (Jean-Luc Marion and Michel Henry) illuminates his stance more fully. I begin with a brief outline of Ricœur’s claims about the distinction or relation between the discourses, then reflect on those of Marion and Henry, who although they do not relate them in the same way still together form a significant contrast to Ricœur’s perspective, and conclude with a fuller consideration of Ricœur’s methodology in light of this comparison. I suggest that it is in particular his hermeneutic commitments that lead him both to more rigorous distinctions between discourses and ironically to greater mediation.

Published: June 2015

This paper is based on the comparison of Pakistani open-ended and close-ended mutual funds performance. That study focus on income, balance and equity schemes of open-ended and close-ended mutual funds. The performance of these funds evaluates using Sortino measure, Shrape measure, Treynor measure, Jenssen differtial measure and Inforamtion measure. The sample for the study consists of 73 funds from 2007 to 2012. Results show open-ended mutual funds performance is better than close-ended mutual funds. KSE (market portfolio) performance is grater over the all sample base mutual funds. Most risk adjusted funds returns are negative, which probably due to mutual fund industry set back by financial crisis during sample period.
An Electrostatic Spinning Technology with Improved Functionality for the Manufacture of Nanomaterials from Solutions
Authors: Pokorny Marek , Novak Jindrich , Rebicek Jiri , Klemes Jan , Velebny Vladimir
Published: June 2015

The last decade has seen an extensive development of the field of nanomaterials which are currently being used in their first commercial applications. This rapid development is necessarily connected with certain technological demands. This paper describes a technology for the manufacture of nanomaterials from solutions by electrostatic spinning or spraying. Although this method has been well known since the last century, there are still only a few high-quality devices that can be used for the research of new nanomaterials. The main reason for this is that the process of nanomaterials manufacturing is influenced by numerous processing parameters which need to be properly regulated, and furthermore all device components must be resistant to interference from high voltage. The technological requirements are thus stringent. Moreover, such a device must be multifunctional, compact and affordable. This paper describes the technical aspects of a unique laboratory device, i.e., device modules and central control, measured processing parameters, and their effect on the produced materials. The developed laboratory device meets the most demanding criteria for a nanotechnological laboratory device and helps facilitate and speed up the research and development of new nanomaterials produced in high electrostatic field.
A Library in the Palm of Your Hand: Mobile Services in Top 100 University Libraries
Authors: Liu Yan Quan , Briggs Sarah
Published: June 2015

What is the current state of mobile services among academic libraries of the country’s top 100 universities, and what are the best practices for librarians implementing mobile services at the university level? Through in-depth website visits and survey questionnaires, the authors studied each of the top 100 universities’ libraries’ experiences with mobile services. Results showed that all of these libraries offered at least one mobile service, and the majority offered multiple services. The most common mobile services offered were mobile sites, text messaging services, e-books, and mobile access to databases and the catalog. In addition, chat/IM services, social media accounts and apps were very popular.  Survey responses also indicated a trend towards responsive design for websites so that patrons can access the library’s full site on any mobile device. Respondents recommend that libraries considering offering mobile services begin as soon as possible as patron demand for these services is expected to increase.

The clash of principles between protecting privacy and protecting security can create an impasse between libraries, campus IT departments, and academic administration over authentication issues with the public area PCs in the library. This research takes an in-depth look at the state of authentication practices within a specific region (i.e. all the academic libraries in North Carolina) in an attempt to create a profile of those libraries that choose to authenticate or not.  The researchers reviewed an extensive amount of data to identify the factors involved with this decision.
Exploratory Subject Searching in Library Catalogs: Reclaiming the Vision
Authors: Bauder Julia , Lange Emma
Published: June 2015

Librarians have had innovative ideas for ways to use subject and classification data to provide an improved online search experience for decades, and yet, after thirty-plus years of improvements in online catalogs, users continue to struggle with narrowing down their subject searches to produce manageable lists containing only relevant results. This article reports on one attempt to rectify that situation by radically re-envisioning the library catalog interface, enabling users to interact with and explore their search results in a profoundly different way. This new interface gives users the option of viewing a graphical overview of their results, grouped by discipline and subject. Results are depicted as a two-level treemap, which gives users a visual representation of the disciplinary perspectives (as represented by the main classes of the Library of Congress Classification) and topics (as represented by elements of the Library of Congress Subject Headings) included in the results.
Megalithic Sites in the District of Sinjai, South Sulawesi, Indonesia
Authors: (Hasanuddin) Hasanuddin
Published: June 2015

Research was conducted in the Sinjai District (South Sulawesi) on three sites linked in alliance called Tellu Limpoe. The findings are mostly earthenware and ceramic fragments of various dynasties. Other findings include dakon (pit marked stones), distributions of stone of various shapes and sizes, and stone mortar with various holes of different sizes. In addition to grinding grain, these objects were also used as clean water reservoirs to meet the needs of supporting human life. All of the archaeological remains discovered indicate the dynamics of life, including household, religious, subsistence, and trade activity. The settlement system is more likely influenced by geographic factors than anything else, due to the hills and mountains that comprise the Sinjai area. The source material supports the interpretation that the natural environment provides enough (fertile) resources that can be used directly by humans.
A Sky-Lecture by the Buddha
Authors: Brown Robert L.
Published: June 2015

There is a group of sculptures that display a Buddha standing on a winged creature, often flanked by two attendants. These sculptures are associated with the Dvāravatī style of art, date to ca. 7th and 8th centuries, and are almost entirely stone. They are unique in the iconography of Buddhist art. Scholars have searched without success for the meaning of these sculptures, looking for possible narrative explanations in Buddhist texts. It is probable that they were associated with stone Wheels of the Law and were raised together with the Wheels on stone pillars. I propose that rather than a specific narrative, they represent the Buddha elevated in the sky and giving a lecture on his Law (dharma). The act of giving a teaching while elevated in the sky is found in numerous textual episodes, an act that the Buddha performed in order to awe and impress listeners on the ground so that they will accept his teachings, or to dominate in a contest with another spiritual teacher. The Wheel of the Law that was the backing of the Flying Buddha represents the Law itself, which was the substance of his lecture.
De la danse au musée : mémoires de l’oeuvre chorégraphique contemporaine
Authors: Côté Julie-Anne
Published: June 2015

La notion de patrimoine culturel s’est élargie ces dernières années. Traditionnellement associée aux monuments et aux sites sous l’angle de leurs valeurs esthétiques et historiques, elle englobe maintenant les traditions et les pratiques sociales, mais aussi les arts du spectacle, dont la danse. L’élargissement de la notion de patrimoine pose la question des nouveaux objets patrimoniaux et muséaux dont les aspects vivants, contemporains, intangibles ou immatériels sont régis par des valeurs qui s’opposent aux valeurs traditionnelles des musées. Ainsi, quoique la conservation et la valorisation du patrimoine de la danse apparaissent nécessaires, elles n’en restent pas moins complexes, particulièrement en ce qui touche l’oeuvre chorégraphique contemporaine en Occident. La danse contemporaine requiert des modes singuliers de mémoire qui supposent diverses perspectives de transmission et de mise en mémoire. Après avoir situé la danse par rapport à la notion de patrimoine culturel immatériel, ce texte présente le double registre de la mémoire de la danse contemporaine : une mémoire documentaire et matérielle et une mémoire vivante et créative. L’étude du Musée de la danse de Boris Charmatz montre comment cette mémoire vivante et créatrice de la danse est mise en oeuvre et l’examen du projet d’exposition virtuelle de la Fondation Jean-Pierre Perreault présente la mise en valeur d’une mémoire documentaire et matérielle. Ces deux formes de mise en mémoire d’oeuvres chorégraphiques contemporaines illustrent de nouvelles perspectives de sauvegarde et de muséalisation d’un patrimoine vivant.
La cybermuséologie et ses nouveaux objets culturels : mise en contexte et étude de cas

Published: June 2015

Musées et expositions virtuels sont-ils synonymes de musées et d’expositions en ligne ? Pourquoi certains chercheurs préconisent-ils l’emploi des désignations cybermusée et cyberexposition ? Peut-on considérer ces productions médiatiques comme étant de nouveaux objets culturels ? En quoi le sont-ils ? En plus de proposer des réponses à ces questions, cet article met de l’avant un certain appareil critique, permettant ainsi d’appréhender l’étude d’un corpus cybermuséal précis. La cybermuséologie, spécialisation de la muséologie contemporaine, commande une réflexion certaine. Celle-ci est souhaitable, voire nécessaire pour envisager toute production relative à ce domaine.
Comment capturer le patrimoine culturel immatériel : réflexions autour de la patrimonialisation de la fauconnerie
Authors: Ruiz Mauricio
Published: June 2015

Cet article aborde la patrimonialisation d’un item protégé par la « Convention pour la sauvegarde du patrimoine culturel immatériel de l’humanité » de l’UNESCO depuis 2010 : « La fauconnerie, un patrimoine humain vivant ». Suivant une brève description de la fauconnerie, au moyen de laquelle est notée son essence immatérielle, l’auteur poursuit l’analyse du processus conduisant à son intégration dans la sphère du patrimoine mondial. Ce faisant, il semble que la réussite d’un tel projet demeure compromise en raison de difficultés que présente sa médiatisation dans l’espace public. Cette investigation débouche alors sur l’identification de trois enjeux sémiotiques sous-jacents à ces problèmes et espère, par là, mener une réflexion dans le domaine de la muséologie désireuse d’accueillir l’immatériel au rang de ses principales préoccupations de recherche.

Resum: El ms. 4504 de Bibliothèque Mazarine de París aplega, per una banda, cinc exemplars impresos de la “Peregrinació del Venturós Pelegrí” ab les “Cobles de la Mort” i, per altra banda, una còpia manuscrita parcial del Venturós Pelegrí amb una traducció francesa incompleta a cura de Josep Tastu (1787-1849), que s’encarregà de compilar tots els materials del volum. A banda de presentar el contingut general del ms. 4504, descrivim amb detall cada una de les cinc edicions, posant especial èmfasi en la més antiga, probablement datada de mitjan segle XVI o poc després. Pel fet d’ésser el testimoni més antic que coneixem del Venturós Pelegrí, aquest exemplar acèfal i àpode, estampat a línia seguida amb tres gravats encara visibles, aporta dades rellevants per al coneixement de les vies de difusió d’aquesta obra als segles XVI-XVII. Paraules clau: Edad Moderna, Poesia catalana, Impremta, Xilografia, Josep Tastu.  Abstract: The Ms. 4504 of the Bibliothèque Mazarine in Paris contains, on the one hand, five printed copies of the “Peregrinació del Venturós Pelegrí” ab les “Cobles de la Mort” and, on the other hand, a partial hand-written copy of the Venturós Pelegrí with an incomplete French translation by Josep Tastu (1787-1849), who compiled all the materials of this volume. Apart from presenting the general content of the ms. 4504, we describe in detail the five editions with particular emphasis on the oldest one, probably dating from the mid-sixteenth century or shortly thereafter. This printed book, now acephalous and apodous, in which the lines go all the way across the page, still preserves three woodcuts. As the earliest witness we know of the Venturós Pelegrí, this printed copy provides some evidences to understand the dissemination of this work during the sixteenth and seventeenth centuries.Keywords: Modern Age, Catalan poetry, Printing, Woodcut, Josep Tastu.

«Temeritats enlluernadores»: La ciutat en la poesia de Bartomeu Rosselló-Pòrcel
Authors: Bou Enric
Published: June 2015

Resum: La poesia de Rosselló-Pòrcel és una obra de dimensió limitada, però d’una gran diversitat. En els últims anys s’ha estudiat amb precisió la presència d’un llegat postsimbolista. En aquest article s’analitza un aspecte menystingut: el sentit de la presència de mons urbans en la poesia de Rosselló-Pòrcel. El poeta experimenta amb un nou concepte de la metàfora i incorpora els elements que componen l'escenari urbà nomenats amb ajuda d'un lèxic despullat del tabú del prosaisme. L’adjectivació, a més, farà possible unir l'experiència del que és descriptiu amb la desrealització de l'objecte contemplat. L’anàlisi detinguda de tres poemes complementa la reflexió.   Paraules clau: Poesia urbana, postsimbolisme     Abstract: Rosselló-Pòrcel’s poetry is a work of limited extension, but of great diversity. In recent years critics have studied with precision the presence of a post-symbolist legacy. In this article I take a look at an undervalued aspect of it: the meaning and uses of urban worlds in his poetry. The poet experimented with a new concept of metaphor and incorporates elements from the urban scene using a lexicon that includes prosaic elements. Adjectives make possible the combination of description with object contemplation. The thorough analysis of three poems completes the re-evaluation.  Keywords: Poetry City PostSymbolism
Oscillations in a Growth Model with Capital, Technology and Environment with Exogenous Shocks
Authors: Zhang Wei Bin
Published: June 2015

This paper generalizes the dynamic growth model with wealth accumulation, technological change and environmental change by Zhang (2012) by making all the parameters as time-dependent parameters. The model treats physical capital accumulation, knowledge creation and utilization, and environmental change as endogenous variables. It synthesizes the basic ideas of the neoclassical growth theory, Arrow’s learning-by-doing model and the traditional dynamic models of environmental change within a comprehensive framework. The behavior of the household is described with an alternative approach to household behavior. We simulated the model to demonstrate existence of equilibrium points, motion of the dynamic system, and oscillations due to different exogenous shocks.
Central European Free Trade Agreement (CEFTA) 2006 - Opportunities, Trade Relation and Evolution of Macedonian Economic Diplomacy
Authors: Efremov Krum
Published: June 2015

Main activity in the foreign trade policy of the Republic of Macedonia during the past 10 years was the integration of the country on the Central European Free Trade Agreement – (CEFTA). The reason for this is the expectation that the membership of the Republic of Macedonia in CEFTA will significantly contribute to the continual efforts for strengthening the regional trade cooperation, further liberalisation of foreign trade exchange, and continuation of activities for harmonisation of trade rules with international standards. Additionally, CEFTA 2006 provides a much more comprehensive framework for development of mutual relations and economic cooperation among the countries of South Easte Europe. We will explain the concept of development of economic diplomacy in the Republic of Macedonia as a tool for supporting Macedonian economy. The purpose of these activities is to present the Republic of Macedonia as an attractive destination for foreign investments through the promotion of business advantages, and giving incentive to Macedonian export, as well as through strengthening of the country’s position as a attractive touristic destination.

Development and function of highly polarized cells such as neurons depend on microtubule-associated intracellular transport, but little is known about contributions of specific molecular motors to the establishment of synaptic connections. In this study, we investigated the function of the Kinesin I heavy chain Kif5aa during retinotectal circuit formation in zebrafish. Targeted disruption of Kif5aa does not affect retinal ganglion cell differentiation, and retinal axons reach their topographically correct targets in the tectum, albeit with a delay. In vivo dynamic imaging showed that anterograde transport of mitochondria is impaired, as is synaptic transmission. Strikingly, disruption of presynaptic activity elicits upregulation of Neurotrophin-3 (Ntf3) in postsynaptic tectal cells. This in turn promotes exuberant branching of retinal axons by signaling through the TrkC receptor (Ntrk3). Thus, our study has uncovered an activity-dependent, retrograde signaling pathway that homeostatically controls axonal branching.
Intermolecular epistasis shaped the function and evolution of an ancient transcription factor and its DNA binding sites
Authors: Anderson Dave W , McKeown Alesia N , Thornton Joseph W
Published: June 2015

Complexes of specifically interacting molecules, such as transcription factor proteins (TFs) and the DNA response elements (REs) they recognize, control most biological processes, but little is known concerning the functional and evolutionary effects of epistatic interactions across molecular interfaces. We experimentally characterized all combinations of genotypes in the joint protein-DNA sequence space defined by an historical transition in TF-RE specificity that occurred some 500 million years ago in the DNA-binding domain of an ancient steroid hormone receptor. We found that rampant epistasis within and between the two molecules was essential to specific TF-RE recognition and to the evolution of a novel TF-RE complex with unique derived specificity. Permissive and restrictive epistatic mutations across the TF-RE interface opened and closed potential evolutionary paths accessible by the other, making the evolution of each molecule contingent on its partner's history and allowing a molecular complex with novel specificity to evolve.

Prácticas Pedagógicas Para la Enseñanza de la Lectura Inicial: Un Estudio en el Contexto de la Evaluación Docente Chilena
Authors: Medina Lorena , Valdivia Andrea , San Martín Ernesto
Published: June 2015

Se presentan los resultados de un estudio centrado en las prácticas de enseñanza de la lectura en los 2 primeros años de la educación básica y los enfoques que le subyacen. Se usó una metodología mixta sobre una muestra aleatoria de 90 videos de docentes de 1º y 2º año básico, en el contexto de la Evaluación Docente chilena del año 2008. Se caracterizaron las prácticas a partir de esos enfoques, a través de la observación de las actividades realizadas en el aula y cómo estas son desarrolladas en la interacción. Se realizaron análisis descriptivos, factorial exploratorio y de diferencias individuales. Los resultados acerca de las actividades mostraron que los docentes desarrollan la lectura por sobre otros ejes del subsector, protagonizando las actividades y formulando las preguntas. Los docentes mejor evaluados tienden a desafiar más a sus estudiantes cognitivamente. Las interacciones en el aula se caracterizan por el dominio del discurso docente, con escasa participación de los estudiantes, las oportunidades de ampliar vocabulario y adquirir conceptos metalingüísticos son restringidas y el desafío cognitivo para el lector es poco exigente.
Intervenciones y Factores Contextuales del Aula que Promueven la Auto-regulación del Aprendizaje: Dos Intervenciones en el Aula Primaria en el Reino Unido
Authors: Pino-Pasternak Deborah , Basilio Marisol , Whitebread David
Published: June 2015

Este artículo tiene 2 propósitos: (a) identificar prácticas pedagógicas y contextos de aula que, según la literatura, promueven el aprendizaje auto-regulado y (b) a través de la descripción de 2 intervenciones realizadas en el Reino Unido, ilustrar cómo dichos factores pueden utilizarse en el diseño de programas que fomentan el aprendizaje autoregulado de estudiantes de enseñanza primaria. Utilizando una muestra intencionada de escuelas primarias, ambos estudios investigaron el efecto de prácticas dialógicas, juego y aprendizaje colaborativo en la auto-regulación del aprendizaje y rendimiento académico. El diseño fue cuasi-experimental pre y postest, con grupo control (simultáneo en Estudio 1 y retrospectivo en Estudio 2). Los datos fueron grabados y codificados. En el Estudio 1, el grupo experimental (57 alumnos de primer grado) participó en 8 actividades grupales sobre resolución de problemas. Los ANOVAs revelaron un mejoramiento en aspectos declarativos y en el monitoreo de la auto-regulación, particularmente en estudiantes con bajos niveles de auto-regulación iniciales. En el Estudio 2 (en desarrollo; 108 alumnos de primer, tercer y quinto grado) los alumnos participan en 12 actividades de juego imaginativo y constructivo usando LEGO©, como estímulo para la creación de textos de diferentes géneros. Los resultados preliminares muestran una respuesta positiva de alumnos y profesores al programa
Introducción a la Sección Especial: Psicología en el Aula

El aula es el contexto en el que los y las estudiantes pasan la mayor parte de su tiempo dedicado al logro de aprendizajes y donde los profesores cumplen un rol esencial. En efecto, la investigación muestra que los profesores son una de las influencias más poderosas para el aprendizaje (Hattie, 2009; Nye, Konstantopolous & Hedges, 2004) y, para que esa influencia sea positiva, debemos contar con profesores que involucren cognitivamente a sus estudiantes, promuevan habilidades de resolución de problemas, monitoreen el desarrollo del conocimiento que buscan impartir, entreguen retroalimentación oportuna y los apoyen continuamente en el logro de sus metas de aprendizaje (Hattie, 2009).
