Liquid crystal alignment in cylindrical microcapillaries
Authors: Chychłowski M. , Yaroshchuk O. , Kravchuk R. , Woliński T. 
Published: September 2011

AbstractA variety of alignment configurations of liquid crystals (LCs) inside the glassy cylindrical capillaries is realized by using alignment materials providing different anchoring. The radial configuration with central disclination line is obtained for homeotropic boundary conditions. In turn, the axial, transversal and tilted alignment structures are realized by using materials for planar anchoring. The uniformity and controlling of the latter structures were provided by photoalignment method. This approach can be further used to control LC alignment in the photonic crystal fibers recognized as advanced elements for different optical devices.
Partitioning between “wedge-top” river- and wave-dominated successions: an example from the late Tortonian — early Messinian Terravecchia Formation (NW Sicily)
Authors: Gugliotta Calogero 
Published: September 2011

AbstractDetailed field sedimentological and facies analyses have been performed in the Terravecchia Formation cropping out in NW Sicily, in order to differentiate and describe, for the first time, wave- and river-dominated shallow-marine (deltaic) siliciclastic successions. The latter were deposited filling syntectonic basins, developed between the late Tortonian and early Messinian time, within the wedge-top depozone of the Sicilian Foreland Basin System. It has been observed that river-dominated successions, recording the deposition of small fan-deltas are characterized by fining- to coarsening upward, transgressive-regressive sequences which were mostly deposited filling relatively narrow and often oversupplied basins. These basins were probably located in a proximal sector of the wedge-top depozone, closer to emergent sectors of the chain and probably sheltered from the main marine areas. Wavedominated successions, on the other hand, are characterized by upward fining, mostly transgressive sequences which were deposited filling wider basins open to major marine regions and located in a more distal position of the wedge-top depozone. The documented partitioning between river- and wave-dominated successions, as a function of the position of the sedimentary basin within the wedge-top depozone, is coherent with data from analyses of the deformational patterns of the Terravecchia Formation in this study area. Furthermore, the data here presented could be considered as a preliminary database for future characterization and analysis of siliciclastic reservoirs from Sicilian outcrop analogues.

AbstractDepth distribution profiles of environmental radionuclides (137Cs and 210Pb) have been investigated in soil to elucidate the underlying environment of semi-natural temperate deciduous and/or coniferous forest soils in Slovenia (Žirovski vrh, Idrija, Kočevski Rog, Pohorie, Gorišnica and Rakitna). Surface enrichment of both nuclides was observed at all the sites investigated in this study, suggesting that the soils had undergone little natural or anthropogenic disturbance for at least the last several decades. Apparent annual burial rates of 137Cs (0.1–0.2 cm y−−1) were estimated to be about 1.3 times higher than those of 210Pb at individual sites of different lithology, which suggests strong affinity of 210Pb to soil organic matter. Variability of the vertical distribution profiles of these nuclides depends not only on “in situ” pedology but also on geographical and meteorological conditions, especially precipitation and wind direction.
U-Pb ID-TIMS age of the Tiksheozero carbonatite: expression of 2.0 Ga alkaline magmatism in Karelia, Russia
Authors: Corfu Fernando , Bayanova Tamara , Shchiptsov Vladimir , Frantz Natalia 
Published: September 2011

AbstractThe Tiksheozero carbonatite in northern Russian Karelia is a transitional type between alkaline ultramafic — carbonatitic and alkaline gabbroic suites. The complex is dominated by pyroxenite with a variety of subordinate mafic and ultramafic phases and nepheline syenite. Carbonatite occurs in a main central body and in veins. In this study we have obtained a reliable age for the complex by single grain ID-TIMS U-Pb analyses of zircon and baddeleyite. The age of 1999 ± 5 Ma is important because it places the emplacement of the alkaline complexes in the context of craton-wide extension and break-up events which preceded the initiation of a major Paleoproterozoic orogenic cycle. The Paleoproterozoic age also emphasizes the fact that not all members of the Kola alkaline province are of Paleozoic age.

Galactic Cosmic Ray Modulation Up to Recent Solar Cycles
Cosmic ray neutron monitor counts obtained by different ground-based detectors have been used to study the galactic cosmic ray modulation during the last four solar activity cycles. Since long, systematic correlative studies have been per-formed to establish a significant relationship between the cosmic ray intensity and different helio-spheric activity parameters, and the study is extended to a recent solar cycle (23). In the present work, the yearly average of 10.7 cm solar radio flux and the interplanetary magnetic field strength (IMF, B) have been used to find correlation of the yearly average cosmic ray intensity derived from different neutron monitors. It is found that for four solar cycles (20-23) the cosmic ray intensity is anti-correlated with the 10.7 cm solar radio flux and the IMF, B value with some discrepancy. However, this is in a good positive correlation with the flux of mentioned wavelength for four different solar cycles. The IMF, B shows a weak correlation with cosmic rays for solar cycle 20, and a good anti-correlation for solar cycles 21-23.
Precise computation of the direct and indirect topographic effects of Helmert's 2nd method of condensation using SRTM30 digital elevation model
Authors: Wang Y. 
Published: September 2011

Precise computation of the direct and indirect topographic effects of Helmert's 2nd method of condensation using SRTM30 digital elevation modelThe direct topographic effect (DTE) and indirect topographic effect (ITE) of Helmert's 2nd method of condensation are computed using the digital elevation model (DEM) SRTM30 in 30 arc-seconds globally. The computations assume a constant density of the topographic masses. Closed formulas are used in the inner zone of half degree, and Nagy's formulas are used in the innermost column to treat the singularity of integrals. To speed up the computations, 1-dimensional fast Fourier transform (1D FFT) is applied in outer zone computations. The computation accuracy is limited to 0.1 mGal and 0.1cm for the direct and indirect effect, respectively.The mean value and standard deviation of the DTE are -0.8 and ±7.6 mGal over land areas. The extreme value -274.3 mGal is located at latitude -13.579° and longitude 289.496°, at the height of 1426 meter in the Andes Mountains. The ITE is negative everywhere and has its minimum of -235.9 cm at the peak of Himalayas (8685 meter). The standard deviation and mean value over land areas are ±15.6 cm and -6.4 cm, respectively. Because the Stokes kernel does not contain the zero and first degree spherical harmonics, the mean value of the ITE can't be compensated through the remove-restore procedure under the Stokes-Helmert scheme, and careful treatment of the mean value in the ITE is required.

Published: September 2011

Over the past few months we have been afforded a unique opportunity to evaluate injury rate data prior to, during, and following the historical aberration created by the recent National Football League (NFL) Lockout. During this period (March 11th to July 25th, 2011), professional football players underwent an uncommon offseason, without the normal access to their team's healthcare providers, strength and conditioning professionals, and high-level coaches. With limited access to these professionals and an absence of the structured preseason preparatory conditioning normally progressed over a 14-week period between May and July, we had a unique window of opportunity to evaluate the effects of an alarmingly rapid transition from the start of training camp, which took place 2 days after the end of the Lockout, to the initiation of preseason competition. A glimpse at early data, limited to Achilles tendon injuries, is cause for concern due to an unprecedented number of Achilles tendon ruptures in training camp and the beginning of preseason.

Commentaires sur « Neuroéconomie : une relecture critique »

Neuroeconomics : A Critique of « Neuroeconomics : A Critical Reconsideration ».
Some economists believe that the work of neuroeconomists threatens the theory of economics. Glenn Harrison’s paper "Neuroeconomics : A Critical Reconsideration" provides some support for this threatened view, though some of the points he makes are disguised (Harrison, 2008). The field of neuroeconomics is barely into its teenage years ; and it is trying to do what ? Criticize and redesign the field of economics developed over hundreds of years ? But that is not what neuroeconomics is trying to do, in spite of all the efforts of some economists trying to place it into that shoebox (see the argument in great detail in Caplin and Schotter (2008)). Neuroeconomics is a Mendelian-Economics of sort ; it is a science that is able to generate data by fixing the environment to some degree, varying a single independent variable for its affects, and is able to see each individual’s choices from initiation of the decision-making process to its outcome. Mainstream economics, on the other hand, looks at the average of the outcomes of many individuals and proposes how people chose those outcomes, retroactively. The two fields, neuroeconomics and mainstream economics, are evaluating two sides of the same coin : one with and the other without ceteris paribus ; they are not necessarily in conflict with one another.
Interaction Analysis in Hybrid Learning Environment
Authors: Osorio-Gómez Luz Adriana , Duart Josep M 
Published: September 2011

Interaction analysis in virtual and hybrid learning environments is a complex issue, since it is necessary to go beyond a quantitative approach (number of messages) and obtain information about interaction dynamics in the context of educational activities. This article presents a set of interaction analysis strategies, which were designed during the development of a doctoral thesis in response to the two challenges identified: First, how can interaction be observed? And second, how can interaction be related to academic performance? The strategies designed provide elements for the analysis of educational activities, of asynchronous on-line discussions, of interaction representation and of the relationship between interaction and academic performance. For the analysis of educational activities, elements of sociocultural activity theory were used. For asynchronous on-line discussions, a content analysis of discussion transcripts was performed using a group of categories reflecting the knowledge construction process. Interaction was represented using the forograma technique, which is an alternative strategy for evaluating on-line discussion forums. The relationship between interaction and academic performance was established by comparing interaction dynamics and the academic performance results of the groups selected. Finally, an example is given to show how the strategies are applied.
El análisis de la interacción en ambientes virtuales e híbridos es un tema complejo, puesto que es necesario superar la aproximación cuantitativa, número de mensajes, y lograr información sobre las dinámicas de interacción, en el marco de las actividades educativas. En este trabajo se presenta un conjunto de estrategias para el análisis de la interacción, las cuales se diseñaron durante el desarrollo de una tesis doctoral, como respuesta a dos retos que fueron identificados: ¿cómo observar la interacción?, ¿cómo relacionar la interacción con el rendimiento académico? Las estrategias diseñadas ofrecen elementos para el análisis de las actividades educativas, análisis de las discusiones virtuales asincrónicas, representación de las interacciones y la relación entre la interacción y el rendimiento académico. El conjunto de estrategias permitió reconocer el fenómeno de la interacción en el marco de actividades educativas, así como el proceso o dinámica en la interacción grupal, que muestra la evolución del grupo hacia la construcción de conocimiento. Por otro lado, también permitió analizar los procesos virtuales de interacción y establecer comparaciones entre las dinámicas de los grupos y la relación entre éstas y los resultados de rendimiento académico. Si bien el grupo de estrategias surgen en un estudio específico, ofrecen herramientas que pueden utilizarse en otros contextos. La manera de utilizar las estrategias se ilustra en este artículo con un ejemplo.
Consumption Patterns and Uses of Photography in Digital Era among Communication Students
Authors: Marzal-Felici Javier , Soler-Campillo María 
Published: September 2011

This paper presents the results of a research study exploring consumer behaviour and uses of photography among first-year students of the Degrees in Journalism, Audiovisual Communication, and Advertising and Public Relations in four Spanish universities (University of Malaga, University of Santiago de Compostela, University of the Basque Country and Universitat Jaume I in Castellón). As it is well known, the emergence of digital technologies has caused far-reaching transformations in the field of photography. These changes have affected production, distribution and circulation processes. However, digital technology has particularly changed the concept of photography itself as a means of expression and communication, above all among young people. Changes in how photography is perceived nowadays, brought about by the onset of digitalization, in turn raises a series of questions that merit reflection. To this end, a survey was designed and administered to a total of 467 communication sciences students in Spain. The results of this research reveal, on the one hand, how these communication students relate to the use of photography today; on the other hand, and more importantly, the results throw some light on how to approach the teaching of digital photography in a higher education context.Se presenta una investigación sobre los hábitos de consumo y usos de la fotografía entre estudiantes de primer curso de las licenciaturas en periodismo, comunicación audiovisual y publicidad y relaciones públicas, en cuatro universidades españolas (Universidad de Málaga, Universidad de Santiago de Compostela, Universidad del País Vasco y Universitat Jaume I de Castellón). Como es sabido, la aparición de las tecnologías digitales en el campo de la fotografía ha provocado profundas transformaciones en el panorama fotográfico. Estos cambios han afectado a los procesos de producción, a los modos de distribución y circulación de las imágenes. Pero, sobre todo, ha tenido notables consecuencias en la forma misma de conceptualizar la fotografía como forma de expresión y comunicación, y en los usos de la fotografía, en especial entre los más jóvenes. La digitalización ha contribuido a transformar, asimismo, la propia percepción del medio fotográfico, que merece una reflexión en estos momentos. A tal fin, se ha diseñado una encuesta que ha sido realizada a un total de 467 estudiantes de ciencias de la comunicación de nuestro país. En definitiva, el análisis de las respuestas que ofrece la presente investigación nos ha permitido, por un lado, tomar conciencia sobre cómo se relacionan estos estudiantes de comunicación con el medio fotográfico en la actualidad. Pero, sobre todo, se trata de una investigación que nos ofrece algunas pistas sobre cómo abordar, en plena era digital, la enseñanza de la fotografía en el contexto educativo universitario.
Structures and Archetypal Content in Advertising Communication
Authors: García-García Francisco , Baños-González Miguel , Fernández-Fernández Paloma 
Published: September 2011

The aim of this investigation is the study of publicity from the point of view of the archetypes, following a hermeneutic model of analysis of the content; through this we have studied the presence of the Greek mythological figures in comparison with the characters that appear in the advertising messages of perfumes, which at first allows us to observe the analogy of the gods of the old Greek Mythology with real human archetypes; secondly, it allows us to dig deeper into these advertising contents to know if these stories are purely commercial or if they could be interpreted with other meanings. The results of this analysis show a high participation of the female archetype of the woman as a wife, related to the goddess Hera, and followed by the archetype of the sensuality represented by the Aphrodite goddess and that of the goddess Artemisia or goddess of liberty; in perfume commercials aimed at men, the biggest frequency in the myth of Zeus and of Narcissus is emphasized, as archetypes of power and success, continued by the presence of the myth of Odysseus, the hero’s archetype, known as a model of strategist and intelligence; in commercials aimed at both sexes the myth of Dionysus as archetype of the party and transformation is the most relevant, followed by the myth of the brothers Hera-Zeus that become husbands and fathers of the Greek Panteon of Mithological Gods.Esta investigación tiene como objeto el estudio de la publicidad desde la óptica de los arquetipos, siguiendo un modelo hermenéutico de análisis del contenido; a través de él hemos estudiado la presencia de las figuras mitológicas griegas más conocidas en comparación con los personajes que aparecen en los mensajes publicitarios de perfumes, lo que nos permite observar en primer lugar la analogía de los dioses de la Antigua Mitología Griega con arquetipos humanos reales; en segundo lugar, nos permite profundizar en estos contenidos publicitarios para saber si estos relatos son puramente comerciales o admiten otras interpretaciones. Los resultados de este trabajo revelan la mayor presencia del arquetipo femenino de la mujer como pareja, relacionado con la diosa Hera, modelo de esposa, seguido en frecuencia por el arquetipo de la sensualidad representado por la diosa Afrodita y en tercer lugar el de la diosa Artemisa o la libertad; en los anuncios de perfumes dirigidos al sector masculino destaca la mayor frecuencia del mito de Zeus y de Narciso, como arquetipos del poder y el éxito, seguido del mito de Odiseo, arquetipo del héroe, reconocido como modelo del estratega y la inteligencia; en los anuncios dirigidos a ambos sexos el mito de Dionisos como arquetipo de la fiesta y la transformación es el más relevante, seguido del mito de los hermanos Hera-Zeus que evolucionaron a esposos y padres del Panteón griego.

Aim Arterial extracellular matrix (ECM) remodeling by matrix metalloproteinases (MMPs) is one of the major hallmarks of atherosclerosis. Mimecan, also known as osteoglycin has been implicated in the integrity of the ECM. This study assessed the validity of an enzyme-linked immunosorbent assay (ELISA) developed to measure a specific MMP12-derived fragment of mimecan, MMCN-151, in apolipoprotein-E knockout (ApoE-KO) mice. Methods and Results A mouse monoclonal antibody raised against MMCN-151 was used to develop a competitive ELISA. The assay was validated using samples from 20 ApoE-KO and 20 wild type [C57 BL/6] male mice fed a normal or high-fat diet (HFD) for up to 20 weeks. The technical reliability of the assay was established with intra-assay variability <2% and inter-assay variability < 10%. The lowest limit of quantification of MMCN-151 was 0.5 ng/ml. ApoE-KO mice fed a HFD for 20 weeks had four-fold increased circulating levels of MMCN-151 compared to baseline, whereas MMCN-151 levels in control mice on HFD increased two-fold compared with baseline. After 10 weeks of a HFD, a significant difference in MMCN-151 levels was observed between ApoE-KO and control mice ( P = 0.005) and became more significant at 20 weeks ( P = 0.002). Conclusions The newly developed assay is a reliable detector of MMCN-151 levels which ultimately may be useful indicators of arterial remodeling in patients affected by atherosclerotic disease.
Birth Order Effects on the Separation Process in Young Adults: An Evolutionary and Dynamic Approach
Authors: Ziv Ido , Hermel Orly 
Published: September 2011

Abstract
The present study analyzes the differential contribution of a familial or social focus in imaginative ideation (the personal fable and imagined audience mental constructs) to the separation–individuation process of firstborn, middleborn, and lastborn children. A total of 160 young adults were divided into 3 groups by birth order. Participants’ separation–individuation process was evaluated by the Psychological Separation Inventory, and results were cross-validated by the Pathology of Separation–Individuation Inventory. The Imaginative Ideation Inventory tested the relative dominance of the familial and social environments in participants’ mental constructs. The findings showed that middleborn children had attained more advanced separation and were lower in family-focused ideation and higher in nonfamilial social ideation. However, the familial and not the social ideation explained the variance in the separation process in all the groups. The findings offer new insights into the effects of birth order on separation and individuation in adolescents and young adults.
