O objetivo deste trabalho foi contribuir para a compreensão da dinâmica costeira e conseqüentementefornecer subsídios para o planejamento e manejo de alguns setores da orla litorânea do estado do Paraná.Para isto foi efetuada a caracterização da morfologia e da dinâmica de duas praias arenosas, correlacionadacom a incidência de sistemas frontais sobre a região. A acentuada agitação marítima que acompanha o trajetode sistemas frontais apresenta-se como o maior regulador da dinâmica costeira do sul do Brasil, sendo queos efeitos sentidos na orla podem tornar-se problemas quando atingem áreas ocupadas. A caracterização daspraias foi realizada através de doze levantamentos planialtimétricos mensais em duas praias. Estes perfis foramamostrados na zona emersa e submersa das praias. Na parte submersa foi utilizado o método proposto porQuadros et al. (2002). Com o auxílio dos Boletins de Sistemas Frontais e Boletins de Eventos Notórios - Casosde Agitação Marítima de Grande impacto na América do Sul, disponibilizados pela página do Sistema de Previsãode Ondas - INPE/CPTEC, foi possível efetuar um levantamento da incidência e freqüência destes eventos.Com base nos resultados obtidos foram apresentadas sugestões e recomendações com o objetivo de incentivartrabalhos referentes a este tema, o que, em um futuro próximo, poderia minimizar os problemas decorrentesda interação entre dinâmica costeira e ocupação antrópica da orla, problemas estes que se tornaram comuns no litoral do estado do Paraná.

Genealogies, Family Resemblances, and Ideations: Art Education’s Place of Possibility in the 21st Century
Authors: Castro Juan Carlos 
Published: December 2014

Abstract
Manuel Barkan’s A Foundation for Art Education is close to six decades old. Contained within Barkan’s text are numerous ideas that resemble innovative ideas in education today. Using A Foundation juxtaposed with the report by Mizuko Ito et al., Connected Learning: An Agenda for Research and Design, the author of this essay presents a number of--what Wittgenstein termed--family resemblances to illustrate that the field of art education has a history of innovative ideas that should empower art educators to be leaders in the larger discourses of education.
Cities of Tomorrow: A Synthesis of Virtual and Physical Communities
Authors: Tillander Michelle 
Published: December 2014

Abstract
The pervasive presence of technology impacts methods of expression, identity, forms of social relationships, and ways of learning. Designing educational experiences requires an understanding of the new dynamics being brought on by ubiquitous computing and learning made possible through emergent digital technologies. This essay employs a vision of the contemporary city as a framework in understanding the technical and social aspects of art education in an age of digital visual information. The essay specifically draws on Lynch’s (1960) theory of visual perception of the city, which studies the material image of the city held by its inhabitants. This essay also takes Jacobs’s (1961) considerations beyond forms and tools to the living extensions of individuals and communities. The essay illuminates the argument that technology-mediated communication has transformed our notion of the relation between place and community, and moves beyond discussions of "technology as a tool" to focus on the relational combination of technology, communities, institutions, and societies. In this view, co-location is enacted and represented differently in actual and virtual spaces (Schroeder, 2006), each of which uniquely shape educational interactions.
Cost of Open access publishing in the light of global developments in scholarly publishing: Springer’s Open access initiative
Authors: Friedman Megan 
Published: December 2014

>> See video of presentation (25 min.)BioMed Central is the open access publisher who pioneered this publishing model and has been part of Springer since 2008. We launched our first journal in the year 2000, and have since seen several positive global developments which have helped establish open access as an important trend in the evolvement of scholarly communication. We have consequently observed a steady increase in awareness of open access and specifically, of our wide range of specialist as well as broad interest titles which is reflected in our growing submission numbers.BioMed Central as one of the main open access publishers has helped to establish open access as a new way of making academic research available to researchers and the public, and to introduce a change of the subscription business model in academic publishing and libraries. While BioMed Central also offers a solution for the Green Route of open access (“Open Repository”) the main part of our publishing activity is centred around our fully or “gold” open access journals. BioMed Central and SpringerOpen practise the “author pays” model, whereby the author is asked to pay a fee to cover the publisher’s cost of publishing and distributing the article. While the awareness of open access is growing among the academics, there is still uncertainty among many of how open access works and why they are asked to pay a fee. To cover that fee can still be a major obstacle for a researcher attempting to publish an article in an open access journal, as the SOAP report stated in 2011.I will present an analysis of the most recent open access developments and studies globally; as well as the effect that this has had on a number of factors that play a role in scholarly publishing, such as Impact Factors, citations and awareness of open access among academics. I will give an update on BioMed Central and Springer’s own development in the arena of open access and visibility of research, including experimenting with alternative methods of evaluating research such as Altmetric and the SCImago Journal & Country Rank. I will conclude with an overview of how we are working with research organisations and universities to offer financial support to their researchers in order to cover the fee for publishing in BioMed Central and SpringerOpen journals in the context of our institutional membership program.
Research unlatched in Norway: What influences the use of Open Access and how to boost it?
Authors: Moksness Lars 
Published: December 2014

Open Access (OA) is a democratic way of publishing research and making data freely available for everyone to use. Studies have shown that OA articles enjoyed higher citation rates, and were downloaded and read more frequently than non-OA published articles. OA publications have the potential to reach a wider audience and benefit specialists and laypeople in a variety of professions, such as the law, health and industry sector. Still, the amount of research made available in OA could be a lot better. Additionally, some disciplines use OA more than others. According to a status report from UiT The Arctic University of Norway (UiT) in 2011, it is not the availability of OA archives that is lacking. Rather, the challenge lies with the amount of research made accessible in these archives. Several factors might influence the decision to make research available in OA, and the proposed study aims, ultimately, to uncover which these may be among Norwegian researchers. Subsequently, interventions will be developed and implemented to boost the use of OA in Norway. Interdisciplinary and discipline specific focus group interviews will provide the material to develop a questionnaire for the pilot study. The main study should ideally collect data nationwide, in as many universities, colleges and research institutes as possible. However, due to the scope of such a study, a preliminary study with interventions could initially be conducted at UiT. The data collected will subsequently be used for the development of interventions designed to boost OA use. One such intervention could be a marketing campaign geared towards increasing awareness of OA, possibly with some incentives to researchers for making research openly and freely available. Interventions will initially be implemented locally (UiT), but if successful on a national scale. Success could be measured by an increase in publications in OA journals and data repositories. Furthermore, a follow-up study could be conducted to ascertain the impact of the implemented interventions.

Galápagos coral reef persistence after ENSO warming across an acidification gradient

Published: December 2014

AbstractAnthropogenic CO2 is causing warming and ocean acidification. Coral reefs are being severely impacted, yet confusion lingers regarding how reefs will respond to these stressors over this century. Since the 1982–1983 El Niño–Southern Oscillation warming event, the persistence of reefs around the Galápagos Islands has differed across an acidification gradient. Reefs disappeared where pH < 8.0 and aragonite saturation state (Ωarag) ≤ 3 and have not recovered, whereas one reef has persisted where pH > 8.0 and Ωarag > 3. Where upwelling is greatest, calcification by massive Porites is higher than predicted by a published relationship with temperature despite high CO2, possibly due to elevated nutrients. However, skeletal P/Ca, a proxy for phosphate exposure, negatively correlates with density (R = −0.822, p < 0.0001). We propose that elevated nutrients have the potential to exacerbate acidification by depressing coral skeletal densities and further increasing bioerosion already accelerated by low pH.
Magnetospheric boundary perturbations on MHD and kinetic scales
Authors: Chen S‐H , Le G , Fok M‐C 
Published: December 2014

AbstractTo study the magnetopause on both MHD and kinetic scales, we have analyzed two Time History of Events and Macroscale Interactions during Substorms/Acceleration, Reconnection, Turbulence, and Electrodynamics of the Moon's Interaction with the Sun magnetopause crossings under steady slow‐solar wind and minimum magnetic shear conditions. These events approximate a ground state of the magnetospheric boundary with minimum influences from large‐solar wind disturbances and magnetic reconnection. Our observations reveal evidence for the Kelvin‐Helmholtz instability, the quasi‐periodicity of magnetopause surface waves accompanied by highly asymmetrical plasma signatures between the inbound (from magnetosheath to low‐latitude boundary layer (LLBL)) and the outbound (from LLBL to magnetosheath) magnetopause crossings. Stronger plasma and magnetic gradients were observed during the outbound crossings but more gradual and volatile variations at higher frequencies during the inbounds. The scale lengths of the magnetic and plasma gradients were comparable or less than the proton gyroradius. Enhancements of lower hybrid waves occurred at the locations of strong gradients or variations. We interpreted the collocations of the lower hybrid waves and plasma gradients and their variations in terms of (1) lower hybrid instabilities that directly convert solar wind flow energy into lower hybrid waves and other wave modes in the LLBL, or (2) Kelvin‐Helmholtz instability and magnetic reconnection which produce the conditions for the lower hybrid instabilities to grow. The rate of ion diffusion across the magnetopause caused by the lower hybrid instability is marginally sufficient to populate the LLBL. The diffusion coefficient of O+ is ~30 times larger than that of H+. The lower hybrid waves could contribute to the energy dissipation at plasma gradients in magnetopause surface wave structures and limit Kelvin‐Helmholtz instability growth further downstream.
Generation of high‐frequency electric field activity by turbulence in the Earth's magnetotail
Authors: Stawarz J. E. , Ergun R. E. , Goodrich K. A. 
Published: December 2014

AbstractBursty bulk flow (BBF) events, frequently observed in the magnetotail, carry significant energy and mass from the tail region at distances that are often greater than 20 RE into the near‐Earth plasma sheet at ∼10 RE where the flow is slowed and/or diverted. This region at ∼10 RE is referred to as the BBF braking region. A number of possible channels are available for the transfer or dissipation of energy in BBF events including adiabatic heating of particles, the propagation of Alfvén waves out of the BBF braking region and into the auroral region, diverted flow out of the braking region, and energy dissipation within the braking region itself. This study investigates the generation of intense high‐frequency electric field activity observed within the braking region. When present, these intense electric fields have power above the ion cyclotron frequency and almost always contain nonlinear structures such as electron phase space holes and double layers, which are often associated with field‐aligned currents. A hypothesis in which the observed high‐frequency electric field activity is generated by field‐aligned currents resulting from turbulence in the BBF braking region is considered. Although linear Alfvén waves can generate field‐aligned currents, based on theoretical calculations, the required currents are likely not the result of linear waves. Observations from the Time History of Events and Macroscale Interactions during Substorms satellites support the picture of a turbulent plasma leading to the generation of nonlinear kinetic structures. This work provides a possible mechanism for energy dissipation in turbulent plasmas.
Daytime tweek atmospherics

Published: December 2014

AbstractWe report the first observation of daytime tweek atmospherics based on measurements at Moshiri (44.37°N, 142.27°E) and Kagoshima (31.48°N, 130.72°E), Japan, during nonsolar eclipse days for 5 months in 1980–1994. The daytime tweeks were observed on geomagnetically quiet and stormy days. The daytime tweeks had clear frequency dispersion with an average duration of 12 ms, which was shorter than that in the nighttime (~50 ms). The average occurrences of the daytime tweeks at Moshiri and Kagoshima were 0.6 and 0.1 tweeks per minute during 10:00–15:00 LT, respectively. Daytime tweeks up to the second‐order mode were visible. There was no difference in the occurrence of each visible mode between storm time and magnetically quiet time. The daytime reflection heights were similar to those at night (85–100 km) but with greater variation. We evaluated the attenuation rate (αn) of tweeks by strictly taking the ionospheric reflection coefficient into account. For each frequency, αn was evaluated as a function of the electron density, electron density gradient, and ionospheric height. We found that αn had an inverse relationship with the electron density (or conductivity), electron density gradient, and ionospheric height. We suggest that the best conditions for daytime tweek observations are when the bottomside of the ionosphere is sharply defined and the ionospheric height is high.
Poynting flux‐conserving low‐altitude boundary conditions for global magnetospheric models

Published: December 2014

AbstractA method for specifying low‐altitude or inner boundary conditions that conserve low‐frequency, magnetic field‐aligned, electromagnetic energy flux across the boundary in global magnetospheric magnetohydrodynamics (MHD) models is presented. The single‐fluid Lyon‐Fedder‐Mobarry (LFM) model is used to verify this method, with comparisons between simulations using LFM's standard hardwall boundary conditions and the new flux‐conserving boundary conditions. Identical idealized upstream solar wind and interplanetary magnetic field conditions and the same constant ionospheric conductance are used in both runs. The results show that, compared to LFM's standard hardwall boundary conditions, the flux‐conserving method improves the transparency of the boundary for the flow of low‐frequency (essentially DC) electromagnetic energy flux along field lines. As a consequence, the hemispheric integrated field‐aligned DC Poynting flux just above the boundary is close to the hemispheric total Joule heating of the ionosphere, as it should be if electromagnetic energy is conserved. The MHD velocity and perpendicular currents are well‐behaved near the inner boundary for the flux conserving boundary conditions.
Ion reflection and acceleration near magnetotail dipolarization fronts associated with magnetic reconnection

Published: December 2014

AbstractDipolarization fronts (DFs) are often associated with the leading edge of earthward bursty bulk flows in the magnetotail plasma sheet. Here multispacecraft Time History of Events and Macroscale Interactions during Substorms (THEMIS) observations are used to show that a spatially limited region of counterpropagating ion beams, whose existence is not evident in either the plasma moments or the electric field, is observed on the low‐density side of DFs. The THEMIS magnetic field data are used to establish appropriate comparison cuts through a particle‐in‐cell simulation of reconnection, and very good agreement is found between the observed and simulated ion distributions on both sides of the DF. Self‐consistent back tracing shows that the ion beams originate from the thermal component of the preexisting high‐density plasma into which the DF is propagating; they do not originate from the inflow region in the traditional sense. Forward tracing shows that some of these ions can subsequently overtake the DF and pass back into the high‐density preexisting plasma sheet with an order‐of‐magnitude increase in energy; this process is distinct from other ion reflection processes that occur directly at the DF. The interaction of the reconnection jet with the preexisting plasma sheet therefore occurs over a macroscopic region, rather than simply being limited to the thin DF interface. A more general consequence of this study is the conclusion that reconnection jets are not simply fed by plasma inflow across the separatrices but are also fed by plasma from the region into which the jet is propagating; the implications of this finding are discussed.
Daytime E region field‐aligned irregularities observed during a solar eclipse

Published: December 2014

AbstractThe driving mechanism of the midlatitude field‐aligned irregularities (FAIs) has been in dispute for many years. The experimental observations were carried out during the solar eclipse of 22 July 2009 in Wuhan, China, to study the possibility of the wave‐driven irregularities. A high‐frequency coherent scatter radar was used to detect the E region irregularities. An ionosonde was applied to record the trace of gravity waves in ionosphere. The E region FAIs occurred at the end of the solar eclipse with fluctuant Doppler. At the same time, the oscillations on the fEs (maximum reflecting frequency of Es) curve and in the Doppler velocity of the echoes from the Es layer were also recorded. The data analysis and comparison show that the gravity waves and the FAIs occurred at the same time with the in‐phase variations in amplitude and phase. Thus, the solar eclipse and the gravity waves may play important roles in the occurrence of the irregularities. A schematic diagram of one‐period gravity wave is used to explain the possible gravity wave‐driven mechanism and the Doppler fluctuation in the irregularities. The daytime FAI in midlatitude is a rare phenomenon, even in the condition of solar eclipse. There are only four cases of the E region FAIs observed during a solar eclipse, including our observations. The unique feature of our observations is the synchronized oscillations in the irregularities and in the Es layer, which will help address the outstanding question of the source of the midlatitude E region FAIs.
