Teniendo en cuenta que construir un público es una de las operaciones más complicadas de la cultura contemporánea, existe algo que diferencia a la literatura de autoayuda de otros productos de consumo masivo, cuestión que se refleja en la posición privilegiada que ésta ostenta en el mercado editorial actual. A partir de ello, en este artículo, reflexionamos a propósito de las representaciones que los propios lectores realizan sobre la lectura de autoayuda, atendiendo a la disposición personal y física que los individuos invierten en esta práctica, los escenarios de lectura, y las circunstancias biográficas en que se desarrolla la actividad lectora. Concluimos en que, asignarle a la lectura de autoayuda una función instrumental por excelencia, no deja ver el valor simbólico que esta práctica adquiere en la vida cotidiana: se trata de una lectura que también construye, llena vacíos, repara.

The reading of self-help as an invention of sense: pleasant, creative and reparative readings Abstract: Given that build an audience is one of the most complicated operations of contemporary culture, there is something that differentiates self-help literature of other consumer products, an issue that is reflected in the privileged position it holds in the publishing market current. From this, in this article we reflect about the representations that readers make about reading self-help, attending to personal and physical disposition that individuals invest in this practice, scenarios reading, and biographical circumstances where the reading activity develops. We conclude that, assign reading self-help an instrumental role par excellence, obscures the symbolic value that this practice takes in everyday life: it is a reading that also builds, fills gaps, repairs.

Published: March 2017

Increases in ocean temperature due to climate change are predicted to change the behaviors of marine invertebrates. Altered behaviors of keystone ecosystem engineers such as echinoderms will have consequences for the fitness of individuals, which are expected to flow on to the local ecosystem. Relatively few studies have investigated the behavioral responses of echinoderms to long-term elevated temperature. We investigated the effects of exposure to long-term (∼31 weeks) elevated temperature (∼3 °C above the ambient water temperature) on covering, sheltering and righting behaviors of the sea urchinStrongylocentrotus intermedius. Long-term elevated temperature showed different effects on the three behaviors. It significantly decreased covering behavior, including both covering behavior reaction (time to first covering) and ability (number of covered sea urchins and number of shells used for covering). Conversely, exposure to long-term elevated temperature significantly increased sheltering behavior. Righting response inS. intermediuswas not significantly different between temperature treatments. The results provide new information into behavioral responses of echinoderms to ocean warming.

Abstract
Objective: Presenting our experience with chondrocutaenous flap reconstruction of the ear to obtain more aesthetic results with fewer complications. Background: Satisfactory reconstruction of the ear following a resection of the helix, scapha and anti-helix remains an ongoing problem in plastic surgery. Many techniques had been developed to approach this issue and to minimise the complications raised from resection of tumours as well. However, no studies have yet mentioned specific details of aesthetic outcomes. Methodology: The study is retrospective in design, with accurate description of the ear reconstruction technique and outcomes in series of cases that were performed by the same surgeon on all patients. Twenty patients were included in this study. The collected data included demographics, any post-operative complications, and post-operative measurements of both reconstructed and normal ears. Results: In all cases, all tumours were completely excised with no known post-operative complications such as flap loss, wound infection, dehiscence or haematoma were reported. The mean residual defect was 21.8 mm ranging from 14 mm to maximum of 30 mm in size. The differences in height, width and projection carried the means of 6.8, 4.3 and 3.8 mm respectively. Conclusion: The modified Antia-Buch technique allows preservation of anatomical landmarks and contour of the ear and therefore maintaining normal overall three-dimensional appearance of the reconstructed ear. Reconstruction of 10 mm defects can be confidently performed using this technique with no loss in size. However, due to the potential lobule distortion, we recommend applying this technique to defects only up to 25 mm.

AbstractWater scarcity has become a major constraint to socio‐economic development and a threat to livelihood in increasing parts of the world. Since the late 1980s, water scarcity research has attracted much political and public attention. We here review a variety of indicators that have been developed to capture different characteristics of water scarcity. Population, water availability, and water use are the key elements of these indicators. Most of the progress made in the last few decades has been on the quantification of water availability and use by applying spatially explicit models. However, challenges remain on appropriate incorporation of green water (soil moisture), water quality, environmental flow requirements, globalization, and virtual water trade in water scarcity assessment. Meanwhile, inter‐ and intra‐annual variability of water availability and use also calls for assessing the temporal dimension of water scarcity. It requires concerted efforts of hydrologists, economists, social scientists, and environmental scientists to develop integrated approaches to capture the multi‐faceted nature of water scarcity.
Bayesian identification of multiple seismic change points and varying seismic rates caused by induced seismicity
Authors: Montoya‐Noguera Silvana , Wang Yu 
Published: March 2017

AbstractThe Central and Eastern United States (CEUS) has experienced an abnormal increase in seismic activity, which is believed to be related to anthropogenic activities. The U.S. Geological Survey has acknowledged this situation and developed the CEUS 2016 1 year seismic hazard model using the catalog of 2015 by assuming stationary seismicity in that period. However, due to the nonstationary nature of induced seismicity, it is essential to identify change points for accurate probabilistic seismic hazard analysis (PSHA). We present a Bayesian procedure to identify the most probable change points in seismicity and define their respective seismic rates. It uses prior distributions in agreement with conventional PSHA and updates them with recent data to identify seismicity changes. It can determine the change points in a regional scale and may incorporate different types of information in an objective manner. It is first successfully tested with simulated data, and then it is used to evaluate Oklahoma's regional seismicity.
Rapid decline in river icings detected in Arctic Alaska: Implications for a changing hydrologic cycle and river ecosystems
Authors: Pavelsky Tamlin M. , Zarnetske Jay P. 
Published: March 2017

AbstractArctic river icings are surface ice accumulations that can be >10 km2 in area and >10 m thick. They commonly impact the hydrology, geomorphology, and ecology of Arctic river environments. Previous examination of icing dynamics in Arctic Alaska found no substantial changes in extent through 2005. However, here we use daily time series of satellite imagery for 2000–2015 to demonstrate that the temporal persistence and minimum summertime extent of large icings in part of Arctic Alaska and Canada have declined rapidly. We identified 122 large ephemeral icings, and 70 are disappearing significantly earlier in the summer, with a mean trend of −1.6 ± 0.9 day−1 for fully ephemeral features. Additionally, 14 of 25 icings that usually persist through the summer have significantly smaller minimum extents (−2.6 ± 1.6% yr−1). These declines are remarkably rapid and suggest that Arctic hydroclimatic systems generating icings, and their associated ecosystems, are changing rapidly.

AbstractWe have studied the spatial location relative to the plasmapause (PP) of the most intense electromagnetic ion cyclotron (EMIC) waves observed on Van Allen Probes A and B during their first full precession in local time. Most of these waves occurred over an L range of from −1 to +2 RE relative to the PP. Very few events occurred only within 0.1 RE of the PP, and events with a width in L of < 0.2 RE occurred both inside and outside the PP. Wave occurrence was always associated with high densities of ring current ions; plasma density gradients or enhancements were associated with some events but were not dominant factors in determining the sites of wave generation. Storm main and recovery phase events in the dusk sector were often inside the PP, and dayside events during quiet times and compressions of the magnetosphere were more evenly distributed both inside and outside the PP. Superposed epoch analyses of the dependence of wave onset on solar wind dynamic pressure (Psw), the SME (SuperMAG auroral electrojet) index, and the SYM‐H index showed that substorm injections and solar wind compressions were temporally closely associated with EMIC wave onset but to an extent that varied with frequency band, magnetic local time, and storm phase, and location relative to the PP. The fact that increases in SME and Psw were less strongly correlated with events at the PP than with other events might suggest that the occurrence of those events was affected by the density gradient.
Off‐equatorial current‐driven instabilities ahead of approaching dipolarization fronts
Authors: Zhang Xu , Angelopoulos V. , Pritchett P. L. , Liu Jiang 
Published: March 2017

AbstractRecent kinetic simulations have revealed that electromagnetic instabilities near the ion gyrofrequency and slightly away from the equatorial plane can be driven by a current parallel to the magnetic field prior to the arrival of dipolarization fronts. Such instabilities are important because of their potential contribution to global electromagnetic energy conversion near dipolarization fronts. Of the several instabilities that may be consistent with such waves, the most notable are the current‐driven electromagnetic ion cyclotron instability and the current‐driven kink‐like instability. To confirm the existence and characteristics of these instabilities, we used observations by two Time History of Events and Macroscale Interactions during Substorms satellites, one near the neutral sheet observing dipolarization fronts and the other at the boundary layer observing precursor waves and currents. We found that such instabilities with monochromatic signatures are rare, but one of the few cases was selected for further study. Two different instabilities, one at about 0.3 Hz and the other at a much lower frequency, 0.02 Hz, were seen in the data from the off‐equatorial spacecraft. A parallel current attributed to an electron beam coexisted with the waves. Our instability analysis attributes the higher‐frequency instability to a current‐driven ion cyclotron instability and the lower frequency instability to a kink‐like instability. The current‐driven kink‐like instability we observed is consistent with the instabilities observed in the simulation. We suggest that the currents needed to excite these low‐frequency instabilities are so intense that the associated electron beams are easily thermalized and hence difficult to observe.
Broadband high‐frequency waves detected at dipolarization fronts

Published: March 2017

AbstractDipolarization front (DF) is a sharp boundary most probably separating the reconnection jet from the background plasma sheet. So far at this boundary, the observed waves are mainly in low‐frequency range (e.g., magnetosonic waves and lower hybrid waves). Few high‐frequency waves are observed in this region. In this paper, we report the broadband high‐frequency wave emissions at the DF. These waves, having frequencies extending from the electron cyclotron frequency fce, up to the electron plasma frequency fpe, could contribute ~10% to the in situ measurement of intermittent energy conversion at the DF layer. Their generation may be attributed to electron beams, which are simultaneously observed at the DF as well.

AbstractA technique to quantitatively determine the sheath impedance of the Van Allen Probes Electric Field and Waves (EFW) instrument is presented. This is achieved, for whistler mode waves, through a comparison between the total electric field wave power spectra calculated from magnetic field observations and cold plasma theory and the total electric field wave power measured by the EFW spherical double probes instrument. In a previous study, a simple density‐dependent sheath impedance model was developed in order to account for the differences between the observed and calculated wave electric field. The current study builds on this previous work by investigating the remaining discrepancies, identifying their cause, and developing an improved sheath impedance correction. Analysis reveals that anomalous gains are caused by the spin axis antennas measuring too much electric field at specific densities and frequencies. This is accounted for in an improved sheath impedance model by introducing a density‐dependent function describing the relative effective length of the probe separation, Leff, in addition to the sheath capacitance and resistance values previously calculated. Leff values vary between between 0.5 and 1.2, with values >1 accounting for the anomalous gains and values <1 accounting for the shorting effect at low densities. Applying this improved sheath impedance model results in a significant increase in the agreement level between observed and calculated electric field power spectra and wave powers over the previous model.
Global distribution of neutral wind shear associated with sporadic E layers derived from GAIA
Authors: Shinagawa H. , Miyoshi Y. , Jin H. , Fujiwara H. 
Published: March 2017

AbstractThere have been a number of papers reporting that the statistical occurrence rate of the sporadic E (Es) layer depends not only on the local time and season but also on the geographical location, implying that geographical and seasonal dependence in vertical neutral wind shear is one of the factors responsible for the geographical and seasonal dependence in Es layer occurrences rate. To study the role of neutral wind shear in the global distribution of the Es layer occurrence rate, we employ a self‐consistent atmosphere‐ionosphere coupled model called GAIA (Ground‐to‐topside model of Atmosphere and Ionosphere for Aeronomy), which incorporates meteorological reanalysis data in the lower atmosphere. The average distribution of neutral wind shear in the lower thermosphere is derived for the June–August and December–February periods, and the global distribution of vertical ion convergence is obtained to estimate the Es layer occurrence rate. It is found that the local and seasonal dependence of neutral wind shear is an important factor in determining the dependence of the Es layer occurrence rate on geographical distribution and seasonal variation. However, there are uncertainties in the simulated vertical neutral wind shears, which have larger scales than the observed wind shear scales. Furthermore, other processes such as localization of magnetic field distribution, background metallic ion distribution, ionospheric electric fields, and chemical processes of metallic ions are also likely to make an important contribution to geographical distribution and seasonal variation of the Es occurrence rate.

Published: March 2017

AbstractThe Voyagers 1 and 2 spacecraft flew by Jupiter in March and July of 1979, respectively. The Plasma Science instrument (PLS) acquired detailed measurements of the plasma environment in the equatorial region of the magnetosphere between 4.9 and 4 RJ. While bulk plasma properties such as charge density, ion temperature, and bulk flow were reasonably well determined, the ion composition was only well constrained in occasional regions of cold plasma. The ion data obtained by the PLS instrument have been reanalyzed using physical chemistry models to constrain the composition and reduce the number of free parameters, particularly in regions of hotter plasma. This paper describes the method used for fitting the plasma data and presents the results versus time. Two companion papers describe the composition of heavy ions and present analysis of protons plus other minor ions.
Pickup ion acceleration in the successive appearance of corotating interaction regions
Authors: Tsubouchi K. 
Published: March 2017

AbstractAcceleration of pickup ions (PUIs) in an environment surrounded by a pair of corotating interaction regions (CIRs) was investigated by numerical simulations using a hybrid code. Energetic particles associated with CIRs have been considered to be a result of the acceleration at their shock boundaries, but recent observations identified the ion flux peaks in the sub‐MeV to MeV energy range in the rarefaction region, where two separate CIRs were likely connected by the magnetic field. Our simulation results confirmed these observational features. As the accelerated PUIs repeatedly bounce back and forth along the field lines between the reverse shock of the first CIR and the forward shock of the second one, the energetic population is accumulated in the rarefaction region. It was also verified that PUI acceleration in the dual CIR system had two different stages. First, because PUIs have large gyroradii, multiple shock crossing is possible for several tens of gyroperiods, and there is an energy gain in the component parallel to the magnetic field via shock drift acceleration. Second, as the field rarefaction evolves and the radial magnetic field becomes dominant, Fermi‐type reflection takes place at the shock. The converging nature of two shocks results in a net energy gain. The PUI energy acquired through these processes is close to 0.5 MeV, which may be large enough for further acceleration, possibly resulting in the source of anomalous cosmic rays.
