La participación del público como valor añadido de servicio público para la televisión de proximidad. Estudio de caso de La noche de…, en ETB 2
Authors: Azurmendi Ana , Llorens Carles , López Vidales Nereida , Bas Portero Juan José 
Published: August 2015

Frente a la crítica tradicional que señala a la televisión pública centrada en las audiencias como una televisión más cercana a los modelos comerciales que al servicio público, la literatura contemporánea sitúa, precisamente, en la participación de las audiencias una de las claves de la televisión pública en la era de la digitalización y la convergencia (Castro 2012; Doyle 2010; Kjus 2009; Bardoel 2007). El artículo se centra en el estudio de la participación en las televisiones públicas autonómicas, en particular en dos cuestiones: 1. Si la variedad de cauces de participación existentes en las producciones crossmedia –programa de televisión que cuenta con web propia, foros de expresión de opinión y cuentas sociales en Twitter y Facebook– aumentan la participación efectiva de las audiencias; y 2. Si esta participación puede encuadrarse en el cumplimiento de las obligaciones de servicio público de televisión, especialmente, de las de proximidad. Metodología: Se parte de un análisis descriptivo de la literatura sobre participación de las audiencias y de las formas de participación promovidas por las políticas europeas, estatales y autonómicas. A partir de los resultados obtenidos, se estudia el caso de “la noche de…” un programa de ETB 2. Resultados: Se comprueba que la atención creciente a la participación del público, tanto en la literatura europea y española como en la regulación existente, no tiene un reflejo proporcional en la realidad de la gestión de las televisiones públicas, en particular en las televisiones públicas autonómicas.
CLASSIC STRAIN ENERGY FUNCTIONS AND CONSTITUTIVE TESTS OF RUBBER-LIKE MATERIALS
Authors: Li Xuebing , Wei Yintao 
Published: August 2015

ABSTRACT
Four classic strain energy density (SED) functions for incompressible rubber-like materials, neo-Hookean, Mooney-Rivlin, Yeoh, and Ogden forms, are briefly reviewed. The strain–stress relations of the above-mentioned SED functions for uniaxial, planar (pure shear), and equibiaxial deformation modes and formulas for transforming tensile data to compressive data of these three special deformation modes are given. Three approximate criteria are proposed for judging the validity of test data obtained from various methods. It is found that Treloar's data are the most reasonable among six groups of published data judged using the proposed criteria. Different combinations of Treloar's data were used to determine the parameters of these SED functions. The effects of three special tests on determining the parameters of various SED functions using the curve-fitting tools provided by ABAQUS were analyzed. Uniaxial tension data were found to be sufficient for determining the neo-Hookean, Yeoh, and first-order Ogden models, whereas both uniaxial and equibiaxial data were necessary for determining the Mooney-Rivlin and Ogden (N = 2, 3) models, and planar data were unnecessary to determine the parameters for all reviewed SED functions.

Prinášame informáciu o tvorbe novej metódy vývinovej diagnostiky (S-PMV) určenej pre pediatrov, ale aj odborníkov, ktorí pracujú v oblasti včasnej diagnostiky detí do 3 rokov. Ide o pôvodnú slovenskú metódu, ktorá vzniká na základe potreby aktualizovať a štandardizovať postupy vyšetrení na odhaľovanie rizika oneskoreného vývinu a vývinových porúch. Metóda pozostáva zo súboru dotazníkov určených na vyplnenie rodičmi, ktorých položky prešli viacstupňovým výberom a boli konfrontované s anamnézou a s posúdením dieťaťa pediatrom. S-PMV bol overovaný na vzorke 2710 detí, ktorú sme získali v spolupráci so 45 pediatrami v rámci celého Slovenska. The contribution provides information about creating a new method of developmental diagnostics (S-PMV) designed for pediatricians, as well as professionals working in the field of early diagnostics of children under 3 years. This is the original Slovak method which arises from the need to update and standardize procedures for examinations to detect the risk of delayed development and developmental disorders. The method consists of a set of questionnaires designed to be filled by parents, whose items have gone through a multi-stage selection and were confronted with a history and with assessment of a child by pediatrician. S-PMV was tested on a sample of 2,710 children, which we acquired in cooperation with 45 pediatricians within Slovakia.

V našom príspevku sa venujeme hodnotovým preferenciám adolescentov vo vzťahu k užívaniu psychoaktívnych látok, konkrétne kanabinoidov. Predpokladáme, že užívanie kanabisu súvisí so špecifickým usporiadaním hodnotových preferencií v porovnaní s intaktnou populáciou. Ako výskumnú metódu sme použili Dotazník hodnôt zo štandardizovaného dotazníka HO-PO-MO, ktorého autorom je Vonkomer. Štatistická analýza získaných dát potvrdzuje náš predpoklad. V súlade s citovanými výskumami konštatujeme, že užívanie kanabisu súvisí s odlišnou organizácii hodnotových preferencií, vyhľadávaní nových zážitkov a vo všeobecnosti v definovaní špecifického životného štýlu. In our contribution we are focused on value preferences of the adolescents in the relation with the psychoactive substances usage, concretely cannabinoids. We assumed that the cannabis usage is in the relation with the specific configuration of the value preferences in the comparison with the intact population. We used The Value Questionnaire from the standardized questionnaire HO-PO-MO as a diagnostic method. The author of this method is Vonkomer. Statistical analysis of the acquired data confirmed our assumption. In the accordance with cited researches we allege that the cannabis usage is in the relation with the different value preferences configuration, novelty seeking and definition of the specific life style in general.

Test struktury zájmů (AIST-R): Recenze metody
Authors: Gabrhel Vít 
Published: August 2015

Současnou podobu metody lze jen obtížně hodnotit. Důvodem je skutečnost, že chybí informace pro posouzení naprosté většiny klíčových charakteristik psychodiagnostické metody. Nedozvíme se nic o validitě, o stabilitě měření v čase, o standardizačním vzorku. Uvedené míry reliability ve smyslu vnitřní konzistence pak nedosahují dostatečně uspokojivých hodnot pro individuální diagnostické účely. Metoda tedy nemůže být použita jako standardizovaný psychodiagnotický nástroj. V současném stavu je jediné myslitelné využití to pro výzkumné účely. A přestože je teoretickému zázemí AIST-R věnována značná pozornost (tvoří přibližně dvě třetiny celkového rozsahu manuálu, který má celkem 30 stran), i zde lze identifikovat určité nedostatky či bílá místa. Manuál kromě relativně obsáhlého vstupu do teoretického zázemí AIST-R představuje rovněž interpretační model NemaCode, který má procesu interpretace dodávat novou dynamiku a větší srozumitelnost či vzbudit zájem klienta o proces karierního vývoje (Mezera et al., 2005). Bohužel není řečeno, nakolik se tento systém promítá do systému interpretace v rámci AIST-R, resp. zda neslouží spíše pro zpestření či doplnění informací. Zároveň je nutné dodat, že Hollandova teorie není jednohlasně přijímána, což metoda nereflektuje. Někteří výzkumníci (Spokane, Meir, & Catalano, 2000) např. poukazují na skutečnost, že kongruence mezi pracovním prostředím a osobností sice souvisí s uspokojením z práce a s úspěchem, nicméně síla tohoto vztahu je slabá. A zároveň na základě existujícího výzkumu není možná kauzální interpretace tohoto vztahu, tedy že kongruence vede k pracovní spokojenosti a k úspěchu (Young, Tokar, & Subich, 1998). V neposlední řadě sám Holland přiznává, že jeho teorie ve své orientaci na jednotlivce pomíjí strukturní prvky typu vzdělávací instituce či pracovní trh (Holland, 1997). Navzdory jejich neoddiskutovatelnému vlivu na učiněné karierní volby. Stačí zde poukázat např. na vzdělanostní či profesní reprodukci společnosti (Katrňák, 2004). Absence kritiky je ale překvapivá i proto, že je v manuálu zmíněn jeden z představitelů postmoderních přístupů v karierním poradenství Vance Peavy, sám velmi kritický k expertním přístupům v karierním poradenství (Peavy, 2013). Tedy k přístupům, k nimž je s většími či s menšími výhradami právě Hollandovu teorii zařadit.
Baterie testů pro diagnostiku specifických poruch učení u studentů vysokých škol a uchazečů o vysokoškolské studium: Recenze metody
Authors: Neuwirthová Barbora 
Published: August 2015

Prezentovaný test je, i přes popsané slabiny, využitelný v oblasti školního poradenství (ať již jde o činnost poradenských center při vysokých školách nebo o činnost pedagogicko-psychologických poraden), zejména při diagnostice specifických poruch učení (dyslexie a dysortografie). Jako zásadní se přitom jeví spíše stanovení vhodných intervenčních strategií, než samotné stanovení diagnózy. Pro dobrou analýzu a interpretaci výsledků v rámci jednotlivých subtestů i dílčích škál je ovšem nezbytné dobře rozumět teoriím, vysvětlujícím etiologii a symptomatologii poruch učení, tedy předpokladům, na základě kterých byl test konstruován. Vzhledem k psychometrickým charakteristikám, které test vykazuje, se pro stanovení závěrů a doporučení jeví jako zcela zásadní kvalitativní analýza dosažených výsledků. A jejich rozbor v kontextu anamnestických údajů a dalších vodítek (pozorování, výstupy z předchozích vyšetření, analýza studijních materiálů apod.) Značná opatrnost by na straně administrátora měla být zejména při analýze a interpretaci výsledků dosažených v rámci subtestů Vnímání neznámých grafémů a Vnímání neznámých fonémů. Proto by měl být využíván výhradně psychology a speciálními pedagogy s odpovídající kvalifikací a zkušeností v diagnostice specifických poruch učení.
Detection of ionospheric disturbances driven by the 2014 Chile tsunami using GPS total electron content in New Zealand
Authors: Zhang Xiaohong , Tang Long 
Published: August 2015

AbstractA tsunami propagating in open ocean can produce gravity waves and thus perturb the ionosphere. In this study, we employ a second‐order numerical difference method using GPS total electron content observed in New Zealand to detect the ionospheric disturbances triggered by the Chile tsunami that occurred on 1 April 2014. We observe traveling ionospheric disturbances (TIDs), which have similar horizontal velocity and direction as the tsunami waves, at different times after the event. According to the arrival times, the latter TIDs (about 14.5–15 h after earthquake) can be attributed to the tsunami waves whereas the former one (about 12 h 30 min after earthquake) could be related to other sources. This suggests that besides the propagation velocity and direction, the arrival time is also necessary to distinguish tsunami‐driven TIDs correctly. Furthermore, we observe the phenomenon that the detected tsunami‐driven TIDs are superimposed upon other nontsunami‐driven ionospheric perturbations far away from the epicenter. The superimposed TIDs eventually separate due to their different propagation velocities.
Flow structure caused by a local cross‐sectional area increase and curvature in a sharp river bend
Authors: Vermeulen B. , Hoitink A. J. F. , Labeur R. J. 
Published: August 2015

AbstractHorizontal flow recirculation is often observed in sharp river bends, causing a complex three‐dimensional flow structure with large implications for the morphological and planimetric development of meanders. Several field observations in small‐scale systems show that sharp bends are often found in association with a strong increase in cross‐sectional area, the deposition of outer bank benches, and reattachment bars near the inner bank. Recent studies show that these bends can also occur in large‐scale systems. In this study, we present field measurements of a sharp bend in the Mahakam River, East Kalimantan, Indonesia. The cross‐sectional area increases by a factor of 3 compared with the reach‐averaged cross‐sectional area. Along a river reach of about 150 km, cross‐sectional area correlates strongly with curvature. The field measurements are analyzed together with the results from numerical simulation with a three‐dimensional finite element model, which yields a comprehensive view of the intricate flow structure. In turn, the model is used to validate a new equation that captures the water surface topography dependence on cross‐sectional area variation and curvature. The results show the importance of the increase in cross‐sectional area in the development of horizontal recirculation. Vertical acceleration of the flow into the scour causes the pressure to deviate from a hydrostatic pressure distribution. Strong downflow (up to 12 cm s−1) advects longitudinal momentum toward the bed, causing the flow to concentrate in the lower part of the cross section. This increases the velocity magnitude throughout the cross section, which is expected to maintain the large scour depth found in several bends along the Mahakam River.
Slip model of the 2015 Mw 7.8 Gorkha (Nepal) earthquake from inversions of ALOS‐2 and GPS data
Authors: Wang Kang , Fialko Yuri 
Published: August 2015

AbstractWe use surface deformation measurements including Interferometric Synthetic Aperture Radar data acquired by the ALOS‐2 mission of the Japanese Aerospace Exploration Agency and Global Positioning System (GPS) data to invert for the fault geometry and coseismic slip distribution of the 2015 Mw 7.8 Gorkha earthquake in Nepal. Assuming that the ruptured fault connects to the surface trace of the Main Frontal Thrust (MFT) fault between 84.34°E and 86.19°E, the best fitting model suggests a dip angle of 7°. The moment calculated from the slip model is 6.08 × 1020 Nm, corresponding to the moment magnitude of 7.79. The rupture of the 2015 Gorkha earthquake was dominated by thrust motion that was primarily concentrated in a 150 km long zone 50 to 100 km northward from the surface trace of the Main Frontal Thrust (MFT), with maximum slip of ∼ 5.8 m at a depth of ∼8 km. Data thus indicate that the 2015 Gorkha earthquake ruptured a deep part of the seismogenic zone, in contrast to the 1934 Bihar‐Nepal earthquake, which had ruptured a shallow part of the adjacent fault segment to the east.

AbstractA comprehensive study of the solar wind interaction with the Martian upper atmosphere is presented. Three global models: the 3‐D Mars multifluid Block Adaptive Tree Solar‐wind Roe Upwind Scheme MHD code (MF‐MHD), the 3‐D Mars Global Ionosphere Thermosphere Model (M‐GITM), and the Mars exosphere Monte Carlo model Adaptive Mesh Particle Simulator (M‐AMPS) were used in this study. These models are one‐way coupled; i.e., the MF‐MHD model uses the 3‐D neutral inputs from M‐GITM and the 3‐D hot oxygen corona distribution from M‐AMPS. By adopting this one‐way coupling approach, the Martian upper atmosphere ion escape rates are investigated in detail with the combined variations of crustal field orientation, solar cycle, and Martian seasonal conditions. The calculated ion escape rates are compared with Mars Express observational data and show reasonable agreement. The variations in solar cycles and seasons can affect the ion loss by a factor of ∼3.3 and ∼1.3, respectively. The crustal magnetic field has a shielding effect to protect Mars from solar wind interaction, and this effect is the strongest for perihelion conditions, with the crustal field facing the Sun. Furthermore, the fraction of cold escaping heavy ionospheric molecular ions [(and/or)/Total] are inversely proportional to the fraction of the escaping (ionospheric and corona) atomic ion [O+/Total], whereasandion escape fractions show a positive linear correlation since both ion species are ionospheric ions that follow the same escaping path.

Published: August 2015

AbstractGlobal Navigation Satellite Systems (GNSS) radio occultation (RO) measurements are sensitive to thin ionization layers and small‐scale ionosphere structures. To evaluate error bounds and possible biases in atmospheric retrievals, we characterized ionospheric irregularities encountered in the affected profiles by analyzing the L1 signal‐to‐noise ratio (SNR) variability at E layer altitudes (from 90 km to 130 km). New metrics to analyze statistical effects of small‐scale ionospheric irregularities on refractivity retrievals are proposed. We analyzed refractivity (N) retrievals with Constellation Observing System for Meteorology, Ionosphere and Climate (COSMIC) ROs in 2011. Using refractivity from European Centre for Medium‐Range Weather Forecasts (ECMWF) analysis (NECMWF) as the reference data set, we studied statistical properties of the fractional refractivity bias (ΔN) defined by the difference (NECMWF − N)/NECMWF and averaged in the altitude range from 20 to 25 km for each individual profile. We found that (1) persistently larger variability of the L1 SNR as measured by the interquartile range (IQR) existed when the occultation tangent point was in the 90 km to 110 km altitude range than at higher E layer altitudes; (2) the upper limits on the fractional refractivity bias for COSMIC ROs are 0.06% (for daytime local time), 0.1% (for nighttime local time), and ~0.01% (for all local times); (3) distributions of ΔN are non‐Gaussian (leptokurtic); (4) latitudinal distributions of small and large ΔN for different levels of ionospheric variability show large tails (NECMWF > N) occurring around the Himalaya and the Andes regions, which are possibly due to biases in ECMWF analysis. We conclude that the refractivity bias due to small‐scale irregularities is small below 25 km altitude and can be neglected.
A model of high‐latitude thermospheric density
Authors: Yamazaki Yosuke , Kosch Michael J. , Sutton Eric K. 
Published: August 2015

AbstractWe present an empirical model of the high‐latitude air density at 450 km, derived from accelerometer measurements by the CHAllenging Minisatellite Payload and Gravity Recovery and Climate Experiment satellites during 2002–2006, which we call HANDY (High‐Latitude Atmospheric Neutral DensitY). HANDY consists of a quiet model and disturbance model. The quiet model represents the background thermospheric density for “zero geomagnetic activity” conditions. The disturbance model represents the response of the thermospheric density to solar wind forcing at high latitudes. The solar wind inputs used are the following: (1) solar wind electric field ESW, (2) interplanetary magnetic field (IMF) clock angle CSW, and (3) solar wind dynamic pressure PSW. Both quiet and disturbance models are constructed on the basis of spherical harmonic function fitting to the data. Magnetic coordinates are used for the disturbance model, while geographical coordinates are used for the quiet model. HANDY reproduces main features of the solar wind influence on the high‐latitude thermospheric density, such as the IMF By effect that produces a hemispheric asymmetry in the density distribution.
Ocean tide loading displacements in western Europe: 1. Validation of kinematic GPS estimates
Authors: Penna Nigel T. , Clarke Peter J. , Bos Machiel S. , Baker Trevor F. 
Published: August 2015

AbstractGPS has been extensively used to estimate tidal ground displacements, but the accuracy of this has not been systematically verified. Using more than 20 sites distributed across western Europe, we show that postprocessed kinematic precise point positioning GPS with appropriately tuned process noise constraints is capable of recovering synthetic tidal displacements inserted into real data, with a typical accuracy of 0.2 mm depending on the time series noise. The kinematic method does not result in erroneous propagation of signals from one coordinate component to another or to the simultaneously estimated tropospheric delay parameters. It is robust to the likely effects of day‐to‐day equipment and reference frame changes, and to outages in the data. A minimum data span of 4 years with at least 70% availability is recommended. Finally, we show that the method of reducing apparent coordinate time series noise by constraining the tropospheric delay to values previously estimated in static batch GPS analysis, in fact, results in the suppression of true tidal signals. Using our kinematic GPS analysis approach, periodic displacements can be reliably observed at the 0.2 mm level, which is suitable for the testing and refinement of ocean tide and solid Earth response models.
Ocean tide loading displacements in western Europe: 2. GPS‐observed anelastic dispersion in the asthenosphere
Authors: Bos Machiel S. , Penna Nigel T. , Baker Trevor F. , Clarke Peter J. 
Published: August 2015

AbstractGPS‐observed vertical ocean tide loading displacements show in Cornwall, southwest England, and in Brittany, northwest France, discrepancies of 2–3 mm with predicted values based on the isotropic Preliminary Reference Earth Model for the main tidal harmonic M2, yet in central Europe the agreement is better than 0.5 mm. By comparison of ocean tide models and validation with tide gauge observations, we demonstrate that the uncertainties in the former are too small to cause this disagreement. Furthermore, we find that different local models of the crust and different global elastic reference models derived from seismological observations can only reduce the observed discrepancies to 1–2 mm, which still exceeds the GPS observational uncertainty of 0.2–0.4 mm. It is customary to use the elastic properties of the Earth as given by seismic models. Previously, there has been insufficient evidence to determine how to modify these properties during the transformation from seismic to tidal frequencies to account for possible anelastic dispersion in the asthenosphere, and so this effect has been ignored. If we include this effect, then our discrepancies reduce further to 0.2–0.4 mm. This value is of the same order as the sum of the remaining errors due to uncertainties in the ocean tide models and in the GPS observations themselves. This research provides evidence in western Europe of a reduction of around 8–10% of the seismic shear modulus in the asthenosphere at tidal frequencies. In addition, we find that the asthenosphere absorption band frequencies can be represented by a constant quality factor Q.
