Published: April 2016

Рассмотрена $p$-адическая модель Изинга-Ваннименуса на дереве Кэли порядка $k=2$. В этой модели имеются взаимодействия с ближайшими соседями и со следующими за ближайшими соседями. Исследована модель с помощью нового подхода, основанного на теории меры (в $p$-адическом смысле). Описаны все трансляционно-инвариантные $p$-адические квазигиббсовы меры, ассоциированные с моделью. Как следствие, получена возможность доказательства существования фазового перехода в этой модели. Здесь под фазовым переходом понимается существование по крайней мере двух нетривиальных $p$-адических квазигиббсовых мер таких, что одна из них является ограниченной, а вторая - неограниченной. Использованные методы не действуют в вещественном случае.

Существуют ли $p$-адические инварианты узлов?
Authors: Morozov Aleksei Yur'evich
Published: April 2016

Предлагается использовать вариант Холла-Литтлвуда формулы Россо-Джонса для определения ростков $p$-адических полиномов ХОМФЛИ торических узлов $[m,n]$ как коэффициентов разложения суперполиномов по $q$. При этом их топологическая инвариантность гарантирована по крайней мере на уровне симметрии $[m,n]\leftrightarrow [n,m]$. Это открывает новые возможности для интерпретации суперполиномов как $p$-адических деформаций полиномов ХОМФЛИ и ставит вопрос об обобщениях на другие семейства узлов, что является содержательной задачей для ряда разделов современной теории.

Published: April 2016

Abstract. Organic aerosol is formed and transformed in atmospheric aqueous phases (e.g., cloud and fog droplets and deliquesced airborne particles containing small amounts of water) through a multitude of chemical reactions. Understanding these reactions is important for a predictive understanding of atmospheric aging of aerosols and their impacts on climate, air quality, and human health. In this study, we investigate the chemical evolution of aqueous secondary organic aerosol (aqSOA) formed during reactions of phenolic compounds with two oxidants – the triplet excited state of an aromatic carbonyl (3C∗) and hydroxyl radical (•OH). Changes in the molecular composition of aqSOA as a function of aging time are characterized using an offline nanospray desorption electrospray ionization mass spectrometer (nano-DESI MS) whereas the real-time evolution of SOA mass, elemental ratios, and average carbon oxidation state (OSC) are monitored using an online aerosol mass spectrometer (AMS). Our results indicate that oligomerization is an important aqueous reaction pathway for phenols, especially during the initial stage of photooxidation equivalent to  ∼  2 h irradiation under midday winter solstice sunlight in Northern California. At later reaction times functionalization (i.e., adding polar oxygenated functional groups to the molecule) and fragmentation (i.e., breaking of covalent bonds) become more important processes, forming a large variety of functionalized aromatic and open-ring products with higher OSC values. Fragmentation reactions eventually dominate the photochemical evolution of phenolic aqSOA, forming a large number of highly oxygenated ring-opening molecules with carbon numbers (nC) below 6. The average nC of phenolic aqSOA decreases while average OSC increases over the course of photochemical aging. In addition, the saturation vapor pressures (C∗) of dozens of the most abundant phenolic aqSOA molecules are estimated. A wide range of C∗ values is observed, varying from < 10−20 µg m−3 for functionalized phenolic oligomers to > 10 µg m−3 for small open-ring species. The detection of abundant extremely low-volatile organic compounds (ELVOC) indicates that aqueous reactions of phenolic compounds are likely an important source of ELVOC in the atmosphere.

Abstract. To better understand the secondary air pollution in transboundary air over westernmost Japan, ground-based field measurements of the chemical composition of fine particulate matter ( ≤  1 µm), mixing ratios of trace gas species (CO, O3, NOx, NOy, i-pentane, toluene, and ethyne), and meteorological elements were conducted with a suite of instrumentation. The CO mixing ratio dependence on wind direction showed that there was no significant influence from primary emission sources near the monitoring site, indicating long- and/or mid-range transport of the measured chemical species. Despite the considerably different atmospheric lifetimes of NOy and CO, these mixing ratios were correlated (r2 = 0.67). The photochemical age of the pollutants, t[OH] (the reaction time  ×  the mean concentration of OH radical during the atmospheric transport), was calculated from both the NOx ∕ NOy concentration ratio (NOx ∕ NOy clock) and the toluene ∕ ethyne concentration ratio (hydrocarbon clock). It was found that the toluene / ethyne concentration ratio was significantly influenced by dilution with background air containing 0.16 ppbv of ethyne, causing significant bias in the estimation of t[OH]. In contrast, the influence of the reaction of NOx with O3, a potentially biasing reaction channel on [NOx] / [NOy], was small. The t[OH] values obtained with the NOx ∕ NOy clock ranged from 2.9  ×  105 to 1.3  ×  108 h molecule cm−3 and were compared with the fractional contribution of the m∕z 44 signal to the total signal in the organic aerosol mass spectra (f44, a quantitative oxidation indicator of carboxylic acids) and O3 mixing ratio. The comparison of t[OH] with f44 showed evidence for a systematic increase of f44 as t[OH] increased, an indication of secondary organic aerosol (SOA) formation. To a first approximation, the f44 increase rate was (1.05 ± 0.03)  ×  10−9  ×  [OH] h−1, which is comparable to the background-corrected increase rate observed during the New England Air Quality Study in summer 2002. The similarity may imply the production of similar SOA component, possibly humic-like substances. Meanwhile, the comparison of t[OH] with O3 mixing ratio showed that there was a strong proportional relationship between O3 mixing ratio and t[OH]. A first approximation gave the increasing rate and background mixing ratio of ozone as (3.48 ± 0.06)  ×  10−7  ×  [OH] ppbv h−1 and 30.7 ppbv, respectively. The information given here can be used for prediction of secondary pollution magnitude in the outflow from the Asian continent.

Published: April 2016

Abstract. Particle water (liquid water content, LWC) and aerosol pH are important parameters of the aerosol phase, affecting heterogeneous chemistry and bioavailability of nutrients that profoundly impact cloud formation, atmospheric composition, and atmospheric fluxes of nutrients to ecosystems. Few measurements of in situ LWC and pH, however, exist in the published literature. Using concurrent measurements of aerosol chemical composition, cloud condensation nuclei activity, and tandem light scattering coefficients, the particle water mass concentrations associated with the aerosol inorganic (Winorg) and organic (Worg) components are determined for measurements conducted at the Finokalia atmospheric observation station in the eastern Mediterranean between June and November 2012. These data are interpreted using the ISORROPIA-II thermodynamic model to predict the pH of aerosols originating from the various sources that influence air quality in the region. On average, closure between predicted aerosol water and that determined by comparison of ambient with dry light scattering coefficients was achieved to within 8 % (slope  =  0.92, R2  =  0.8, n  =  5201 points). Based on the scattering measurements, a parameterization is also derived, capable of reproducing the hygroscopic growth factor (f(RH)) within 15 % of the measured values. The highest aerosol water concentrations are observed during nighttime, when relative humidity is highest and the collapse of the boundary layer increases the aerosol concentration. A significant diurnal variability is found for Worg with morning and afternoon average mass concentrations being 10–15 times lower than nighttime concentrations, thus rendering Winorg the main form of particle water during daytime. The average value of total aerosol water was 2.19 ± 1.75 µg m−3, contributing on average up to 33 % of the total submicron mass concentration. Average aerosol water associated with organics, Worg, was equal to 0.56 ± 0.37 µg m−3; thus, organics contributed about 27.5 % to the total aerosol water, mostly during early morning, late evening, and nighttime hours.The aerosol was found to be highly acidic with calculated aerosol pH varying from 0.5 to 2.8 throughout the study period. Biomass burning aerosol presented the highest values of pH in the submicron fraction and the lowest values in total water mass concentration. The low pH values observed in the submicron mode and independently of air mass origin could increase nutrient availability and especially P solubility, which is the nutrient limiting sea water productivity of the eastern Mediterranean.

Published: April 2016

Abstract. This work presents the operational methane retrieval algorithm for the Sentinel-5 Precursor (S5-P) satellite and its performance tested on realistic ensembles of simulated measurements. The target product is the column-averaged dry air volume mixing ratio of methane (XCH4), which will be retrieved simultaneously with scattering properties of the atmosphere. The algorithm attempts to fit spectra observed by the shortwave and near-infrared channels of the TROPOMI spectrometer aboard S5-P. The sensitivity of the retrieval performance to atmospheric scattering properties, atmospheric input data and instrument calibration errors is evaluated. Also, we investigate the effect of inhomogeneous slit illumination on the instrument spectral response function. Finally, we discuss the cloud filters to be used operationally and as backup. We show that the required accuracy and precision of < 1 % for the XCH4 product are met for clear sky measurements over land surfaces and after appropriate filtering of difficult scenes. The algorithm is very stable having a convergence rate of 99 %. The forward model error is less than 1 % for about 95 % of the valid retrievals. Model errors in the input profile of water do not influence the retrieval outcome noticeably. The methane product is expected to meet the requirements if errors in input profiles of pressure and temperature remain below 0.3 % and 2 K, respectively. We find further that, of all instrument calibration errors investigated here, our retrievals are the most sensitive to an error in the instrument spectral response function of the short-wave infrared channel.
Effects of in situ CO2 enrichment on structural characteristics, photosynthesis, and growth of the Mediterranean seagrass Posidonia oceanica

Published: April 2016

Abstract. Seagrass is expected to benefit from increased carbon availability under future ocean acidification. This hypothesis has been little tested by in situ manipulation. To test for ocean acidification effects on seagrass meadows under controlled CO2/pH conditions, we used a Free Ocean Carbon Dioxide Enrichment (FOCE) system which allows for the manipulation of pH as continuous offset from ambient. It was deployed in a Posidonia oceanica meadow at 11 m depth in the Northwestern Mediterranean Sea. It consisted of two benthic enclosures, an experimental and a control unit both 1.7 m3, and an additional reference plot in the ambient environment (2 m2) to account for structural artifacts. The meadow was monitored from April to November 2014. The pH of the experimental enclosure was lowered by 0.26 pH units for the second half of the 8-month study. The greatest magnitude of change in P. oceanica leaf biometrics, photosynthesis, and leaf growth accompanied seasonal changes recorded in the environment and values were similar between the two enclosures. Leaf thickness may change in response to lower pH but this requires further testing. Results are congruent with other short-term and natural studies that have investigated the response of P. oceanica over a wide range of pH. They suggest any benefit from ocean acidification, over the next century (at a pH of  ∼ 7.7 on the total scale), on Posidonia physiology and growth may be minimal and difficult to detect without increased replication or longer experimental duration. The limited stimulation, which did not surpass any enclosure or seasonal effect, casts doubts on speculations that elevated CO2 would confer resistance to thermal stress and increase the buffering capacity of meadows.
Stride Search: a general algorithm for storm detection in high-resolution climate data
Authors: Bosler Peter A. , Roesler Erika L. , Taylor Mark A. , Mundt Miranda R.
Published: April 2016

Abstract. This article discusses the problem of identifying extreme climate events such as intense storms within large climate data sets. The basic storm detection algorithm is reviewed, which splits the problem into two parts: a spatial search followed by a temporal correlation problem. Two specific implementations of the spatial search algorithm are compared: the commonly used grid point search algorithm is reviewed, and a new algorithm called Stride Search is introduced. The Stride Search algorithm is defined independently of the spatial discretization associated with a particular data set. Results from the two algorithms are compared for the application of tropical cyclone detection, and shown to produce similar results for the same set of storm identification criteria. Differences between the two algorithms arise for some storms due to their different definition of search regions in physical space. The physical space associated with each Stride Search region is constant, regardless of data resolution or latitude, and Stride Search is therefore capable of searching all regions of the globe in the same manner. Stride Search's ability to search high latitudes is demonstrated for the case of polar low detection. Wall clock time required for Stride Search is shown to be smaller than a grid point search of the same data, and the relative speed up associated with Stride Search increases as resolution increases.
The role of building models in the evaluation of heat-related risks
Authors: Buchin Oliver , Jänicke Britta , Meier Fred , Scherer Dieter , Ziegler Felix
Published: April 2016

Abstract. Hazard–risk relationships in epidemiological studies are generally based on the outdoor climate, despite the fact that most of humans' lifetime is spent indoors. By coupling indoor and outdoor climates with a building model, the risk concept developed can still be based on the outdoor conditions but also includes exposure to the indoor climate. The influence of non-linear building physics and the impact of air conditioning on heat-related risks can be assessed in a plausible manner using this risk concept. For proof of concept, the proposed risk concept is compared to a traditional risk analysis. As an example, daily and city-wide mortality data of the age group 65 and older in Berlin, Germany, for the years 2001–2010 are used. Four building models with differing complexity are applied in a time-series regression analysis. This study shows that indoor hazard better explains the variability in the risk data compared to outdoor hazard, depending on the kind of building model. Simplified parameter models include the main non-linear effects and are proposed for the time-series analysis. The concept shows that the definitions of heat events, lag days, and acclimatization in a traditional hazard–risk relationship are influenced by the characteristics of the prevailing building stock.
Responses of aeolian desertification to a range of climate scenarios in China
Authors: Wang Xunming , Hua Ting , Ma Wenyong
Published: April 2016

Abstract. Aeolian desertification plays an important role in earth-system processes and ecosystems, and has the potential to greatly impact on global food production. The occurrence of aeolian desertification has traditionally been attributed to increases in wind velocity and temperature, and decreases in precipitation. In this study, by integrating the aeolian desertification monitoring data and climate and vegetation indices, we found that although aeolian desertification is influenced by complex climate patterns and human activities, increases in precipitation and temperature, and decreases in wind speed, may also trigger aeolian desertification in China. Our results show that, even when modern technical approaches are used, different approaches to desertification need to be applied to account for regional differences. These results have important implications for future policy decisions on how best to combat desertification.

Published: April 2016

It cannot be denied that intercultural understanding is crucial in the process of learning English at elementary school, junior high school, high school, and so on. This paper analyzes the high school English textbooks approved by the Ministry of Education, Culture, Sports, Science and Technology (henceforth, MEXT) in Japan from the perspective of intercultural understanding. It elucidates the types of the articles, the countries treated in the articles, and the purposes of the materials for cultural understanding. Then it discusses the characteristics of the cultural materials presented in the high school English textbooks. The result of the research shows the materials contain various kinds of categories, many materials concerning English-speaking countries. However, an important fact is that there is still too much focus on Japan and America. Finally, the paper suggests the future direction of the materials in the textbooks in order to facilitate the better intercultural understanding in the global world.

Role of Environment in Connecting Disabled and Abandoned Children to Society (A case Study of Turning Rofaydeh Welfare Complex Project into a House in a Neighborhood Park)
Authors: Yarmohammad Fateme
Published: April 2016

Due to physical and mental disability, children tend to withdraw themselves from society especially if their parents abandon them, and if society fail to establish a suitable relationship with these children, their presence will uproot from society. In this paper, we deals with the case Rofaydeh Welfare Services Complex in Iran in the he city of Tehran where 60 disabled, mentally or physically disabled children are taken care of, some of them were also orphans. The aim of the article is to provide an environment which is conducive to more relationship and interaction of these children with members of society with regard to their lack of caretaker and family, as well as protecting the primacy of the children's living spaces as their home.

The research methodology included library and field methods; thus, suitable strategies were developed to achieve the goal of this paper. The research indicates that designing the complex as a house in the middle of the neighborhood park allows for children's presence in the society among the people and close interaction with people through being positioned in a neighborhood park, as well as providing the presence of the children in a space similar to a house which is every child's wish. On neighborhood scale, the park protects the children from social damages so that they feel sense of intimacy working between them and people.

Published: April 2016

Due to the higher statistics of male infidelity, the focus of previous studies has been on investigating the reasons for infidelity in this gender group. On the other hand; since marital infidelity is a phenomenon that affects every country’s culture, people, and even families, the results of research studies conducted overseas cannot be fully implicated to Iranian families. To this end, this study aimed at analyzing the reasons behind infidelity in women with extra-marital relationships in the form of a qualitative study. This study was conducted through a qualitative research approach and by using the content analysis method. Participants included 11 women referred to the counseling centers in the city of Isfahan. Purposive sampling was used and continued until data saturation. Semi-structured interviews were employed as the primary method of data collection. The data were analyzed via qualitative content analysis and constant comparative analysis methods. After the examination and division of the basic concepts, 800 initial codes were extracted from interviews. The categories were created based on the codes following several reviews and summarizations on the basis of similarities. By the nature, these conceptual and abstract themes were named in three categories of intrapersonal factors, marital conflicts, and sexual reasons. The factors affecting female infidelity in this study had three dimensions. These factors included intrapersonal factors, marital conflicts, and sexual reasons. These findings can help psychologists, family counselors, and planners in the field of the social sciences identify the efficient scopes and purposes.

Published: April 2016

In this paper, we present the design and testing of a radiofrequency prototype coil with good performances in terms of B1 magnetic field homogeneity and can be utilized for Magnetic Resonance Imaging. It is constituted of four coaxial separately tuned rings of wire and symmetrically located on a spherical surface. Compared to standard Helmholtz pair, which has 2nd-order magnetic field homogeneity, it yields to improvement in field homogeneity, while preserving the simplicity of design. The four coils of proposed structure are tuned to the same frequency. The proposed structure gets at 4th-order magnetic field homogeneity by optimizing the distance between rings and the diameters of outer loops. An electrical modeling of the four-coil system taking into account the coupling effects between all rings permits to determine the resonance frequency in the homogenous mode. Measurements of B1 field homogeneity were introduced in free space. Compared to the Helmholtz coil, the proposed structure presents good performances in terms of B1 homogeneity, quality factor and sensitivity. The design of proposed coil has been optimized for best SNR performances. Globally, this work claims to be a contribution to the study of the four-coil RF systems derived from the Helmholtz pairs.
A Regionalized Stochastic Rainfall Model for the Generation of High Resolution Data in Peninsular Malaysia
Authors: Mohd Daud Zalina , Mat Rasid Siti Musliha , Abas Norzaida
Published: April 2016

High resolution rainfall data is an important input for studies on hydrological systems. Often time synthetic data has to be generated in the absence of historical data.  The stochastic Neyman Scott Rectangular Pulse (NSRP) model has been developed to produce synthetic data of high resolution. To take into account the spatial and temporal nature of rainfall, an extra domain had been added producing the Spatial Temporal NSRP (ST-NSRP) model. However these models require the repeat estimation of all the model parameters for each location. This work develops the Regionalized ST-NSRP model which produces a single model for a region. The regionalization approach is carried out by the station-year method using ten years (2001-2010) of records from sixteen stations. The statistical characteristics used in estimating the model’s parameters are hourly and daily coefficient of variation, hourly and daily lag one auto correlation, hourly cross correlation between sites and hourly skewness of rainfall series. Simulation process is conducted at two independent stations with distinctly different rainfall profile. The Regionalized ST-NSRP model produced statistical characteristics of the ungauged sites which matched those of the observed series fairly well even though there is a tendency to underestimate hourly covariance and lag one autocorrelation. Considering that spatial variability of rainfall is high within the studied region, this model is sufficiently robust in producing reasonable synthetic hourly rainfall series which captured the characteristics and pattern of observed rainfall series. Therefore the model has shown a promising potential in generating high resolution synthetic data for any ungauged site within the region.
El concepto de ironía en la estética de Friedrich Schlegel: contexto y recepción.
Authors: Benéitez Andrés Rosa
Published: April 2016

La teoría schlegeliana acerca de la ironía continúa siendo un referente indiscutible en los estudios dedicados a este concepto. En el ámbito concreto de la Estética y la Teoría de las artes, la noción de ironía elaborada por F. Schlegel ocupa un puesto privilegiado como herramienta de comprensión y exégesis en los análisis de gran cantidad de prácticas artísticas modernas y contemporáneas. Ante la vigencia de su propuesta, resulta preciso insistir en la particularidad del programa schlegeliano frente a otros usos e interpretaciones del proceder irónico. En tal sentido, este artículo tratará de enfatizar en la especificidad de sus ideas sobre el fenómeno, a través de un recorrido, tanto histórico como teórico, del contexto y recepción de esa ironía romántica planteada por el filósofo, así como por otros autores de la Frühromantik.

The relationship reading and writing with cognitive-linguistic factors is analyzed for most studies, being less frequent the studies related with motivation. This study analyse the relation of the motivation and writing composition and reading comprehension, in Spanish teenagers. The sample this formed by 203 subjects of 1º (ME=12.4, DT=1.28), 2º (ME=13.6, DT=1.02) y 3º (ME=14.2, DT=1.34) of compulsory secondary education, of class media sociocultural, with normal intellectual levels and without deficits physical, psychic or sensory. The students were evaluated in motivation in terms of frequency of thoughts about performance of academics tasks. The written composition was evaluated in terms of thematic progression, semantic, morphosyntactic and metacognition. And the reading comprehension evaluated in terms of selection and organization of ideas, semantic, morphosyntactic and metacognition. The design is transversal and we realised analysis of lineal regression. The results obtained indicate that the motivation explains 17% of the written composition and between 16 and 27% of the reading comprehension, according to the academic level. The relationship of motivation and written language in this ages and their potential impact on problems in written composition and reading comprehension in adolescence is emphasized.

Authors: García Trinidad , Rodríguez Celestino , González-Castro Paloma , Álvarez-García David , González-Pienda Julio-Antonio
Published: April 2016

This study analyzes differences in metacognitive skills and executive functioning between two groups of students (10-12 years) with different levels of metacognitive knowledge (high n = 50, low n = 64). Groups were established based on students’ score on a test of knowledge of strategy use. Metacognitive skills were assessed by means of self-report. Students reported the frequency with which they applied these strategies during the phases of planning, execution, and evaluation of learning. Information about student executive functioning was provided by families and teachers, who completed two parallel forms of a behavior rating scale. The results indicated that: a) the group with high levels of metacognitive knowledge reported using their metacognitive skills more frequently than their peers in the other group. These differences were statistically significant in the phases of planning and execution; b) both family and teachers informed of better levels of executive functioning in the students with high metacognitive knowledge. Statistically significant differences were found in planning, functional memory, focus, and sustained attention. These results show the existence of an association between different levels of metacognitive knowledge, and differences in metacognitive skills and executive functions, and suggest the need to emphasize this set of variables in order to encourage students to acquire increasing levels of control over their learning process.

Published: April 2016

This research analyzes the generalization ability of learning in children and adolescents with Asperger Syndrome to attentional cognitive aspects with different demands on exercised through the use of a direct cognitive stimulation program. The sample consisted of 15 cases with Asperger between 7 and 15 years (M = 12, SD = 2.7) with attentional difficulties, measured by psychometric orientation instruments, to which an attention training program was implemented to two hours per week for six consecutive months. The results of the pretest-posttest analysis showed statistically significant differences in all attentional subsystems. Selective attention differences are moderate in variables related to processing speed, in sustained attention the reaction time significantly decreased (moderate magnitude of the difference) and increased the successes reducing errors (both with a large magnitude difference) . In alternating attention, a greater number of successes were observed and in split attention higher levels of total responses (both moderate magnitude) were obtained. It is concluded that the attentional performance in the cases analyzed improvement after applying a cognitive training program specifically being able to generalize learning psychometric measures.
Individual and group antecedents of satisfaction: One lab- multilevel study
Authors: Martínez Isabel M. , Cifre Eva
Published: April 2016

This study examines the simultaneous effect of individual (self-efficacy) and group variables (cohesion and gender diversity) on satisfaction. A laboratory study was conducted involving 373 college students randomly distributed across 79 small groups, who performed a laboratory task in about five hours. Two-level Hierarchical Linear Modeling (HLM) method was used. Results show the main effect from individual self-efficacy to satisfaction (both level 1), the cross-level effect from group cohesion (level 2) to individual satisfaction (level 1), and the interaction effect between self-efficacy and gender diversity to satisfaction. These results suggest that in a work group, satisfaction has a background in individual and group variables. Group cohesion and gender diversity have important effects on satisfaction. The article concludes with practical strategies and with limitations and suggestions for future research.

Authors: Champoux Anne-Frédérique
Published: April 2016

En avril 2014, un comité de travail du Regroupement des bibliothèques collégiales du Québec (REBICQ) mène une enquête afin de dresser un portrait de l’offre de formation documentaire dans le réseau des cégeps et collèges. L’objectif est de recueillir des données actualisées sur les pratiques, les modalités et les contenus des formations proposées aux étudiants du niveau collégial. Les résultats obtenus montrent que la formation documentaire revêt une grande importance dans les bibliothèques du REBICQ ayant répondu à l’enquête, car 100% d’entre elles en proposent. L’étude révèle par ailleurs que les contenus présentés en formation sont pertinents et diversifiés. On constate également que les ateliers en présentiel, s’insérant dans une multitude de cours et programmes, rejoignent chaque année un pourcentage important d’étudiants, soit près de 40 % des cégépiens inscrits à l’enseignement régulier.
Réflexion méthodologique sur l’usage des logiciels Modalisa et Iramuteq pour l’étude d’un corpus de presse sur l’anorexie mentale
Authors: Arnoult Audrey
Published: April 2016

L’anorexie mentale est une maladie polyfactorielle complexe aujourd’hui considérée comme un problème de santé publique par le corps médical. Toutefois, les discours médiatiques sur ce sujet sont relativement récents. Notre contribution vise à comprendre comment se caractérise la couverture médiatique de cette pathologie et quelles représentations construisent les médias de ce trouble lié à l’adolescence tout en montrant en quoi le recours à des logiciels d’analyse automatisée de discours peut nous être utile. Pour cela, nous menons une analyse quantitative et de contenu d’un corpus de 131 articles, publiés entre 1995 et 2009, dans divers quotidiens nationaux, avec le logiciel Modalisa. Puis, nous utilisons le logiciel Iramuteq pour identifier les mondes lexicaux organisant les discours en nous appuyant sur un second corpus, plus restreint.

Estratègia i trascendència dels noms en els Diàlegs de Joan Lluís Vives
Authors: Codonyer Adela
Published: April 2016

En les següents pàgines s’analitzen les estratègies que Vives empra per nomenar els personatges dels Diàlegs, una de les seues obres més populars. Els protagonistes són essencialment els alumnes que van avançant en la seua formació, des de col·legials fins a joves universitaris. Juntament amb ells va progressant també el seu entorn d’acord amb el ritme pedagògic: els centres d’ensenyança, els continguts de l’aprenentatge i les interaccions amb els docents i amb els companys. Poc a poc anirem esbrinant que tot aquest món poblat d’estudiants, els apel·latius dels quals ens transmeten remembrances clàssiques i al·lusions modernes (contemporànies de l’època de Vives), oculta en realitat un sentit més profund.

Cooperative regulation by G proteins and Na+ of neuronal GIRK2 K+ channels
Authors: Wang Weiwei , Touhara Kouki K , Weir Keiko , Bean Bruce P , MacKinnon Roderick
Published: April 2016

G protein gated inward rectifier K+ (GIRK) channels open and thereby silence cellular electrical activity when inhibitory G protein coupled receptors (GPCRs) are stimulated. Here we describe an assay to measure neuronal GIRK2 activity as a function of membrane-anchored G protein concentration. Using this assay we show that four Gβγ subunits bind cooperatively to open GIRK2, and that intracellular Na+ – which enters neurons during action potentials – further amplifies opening mostly by increasing Gβγ affinity. A Na+ amplification function is characterized and used to estimate the concentration of Gβγ subunits that appear in the membrane of mouse dopamine neurons when GABAB receptors are stimulated. We conclude that GIRK2, through its dual responsiveness to Gβγ and Na+, mediates a form of neuronal inhibition that is amplifiable in the setting of excess electrical activity.

Efficient online detection of temporal patterns

Published: April 2016

Identifying a temporal pattern of events is a fundamental task of online (real-time) verification. We present efficient schemes for online monitoring of events for identifying desired/undesired patterns of events. The schemes use preprocessing to ensure that the number of comparisons during run-time is minimized. In particular, the first comparison following the time point when an execution sub-sequence cannot be further extended to satisfy the temporal requirements halts the process that monitors the sub-sequence.
The vertical structure of upper ocean variability at the Porcupine Abyssal Plain during 2012–2013

Published: April 2016

This study presents the characterization of variability in temperature, salinity and oxygen concentration, including the vertical structure of the variability, in the upper 1000 m of the ocean over a full year in the northeast Atlantic. Continuously profiling ocean gliders with vertical resolution between 0.5 and 1 m provide more information on temporal variability throughout the water column than time series from moorings with sensors at a limited number of fixed depths. The heat, salt and dissolved oxygen content are quantified at each depth. While the near surface heat content is consistent with the net surface heat flux, heat content of the deeper layers is driven by gyre‐scale water mass changes. Below ∼150m, heat and salt content display intraseasonal variability which has not been resolved by previous studies. A mode‐1 baroclinic internal tide is detected as a peak in the power spectra of water mass properties. The depth of minimum variability is at ∼415m for both temperature and salinity, but this is a depth of high variability for oxygen concentration. The deep variability is dominated by the intermittent appearance of Mediterranean Water, which shows evidence of filamentation. Susceptibility to salt fingering occurs throughout much of the water column for much of the year. Between about 700–900 m, the water column is susceptible to diffusive layering, particularly when Mediterranean Water is present. This unique ability to resolve both high vertical and temporal variability highlights the importance of intraseasonal variability in upper ocean heat and salt content, variations that may be aliased by traditional observing techniques.
Sensitivity of summer ensembles of fledgling superparameterized U.S. mesoscale convective systems to cloud resolving model microphysics and grid configuration

The sensitivities of simulated mesoscale convective systems (MCSs) in the central U.S. to microphysics and grid configuration are evaluated here in a global climate model (GCM) that also permits global‐scale feedbacks and variability. Since conventional GCMs do not simulate MCSs, studying their sensitivities in a global framework useful for climate change simulations has not previously been possible. To date, MCS sensitivity experiments have relied on controlled cloud resolving model (CRM) studies with limited domains, which avoid internal variability and neglect feedbacks between local convection and larger‐scale dynamics. However, recent work with superparameterized (SP) GCMs has shown that eastward propagating MCS‐like events are captured when embedded CRMs replace convective parameterizations. This study uses a SP version of the Community Atmosphere Model version 5 (SP‐CAM5) to evaluate MCS sensitivities, applying an objective empirical orthogonal function algorithm to identify MCS‐like events, and harmonizing composite storms to account for seasonal and spatial heterogeneity. A five‐summer control simulation is used to assess the magnitude of internal and interannual variability relative to 10 sensitivity experiments with varied CRM parameters, including ice fall speed, one‐moment and two‐moment microphysics, and grid spacing. MCS sensitivities were found to be subtle with respect to internal variability, and indicate that ensembles of over 100 storms may be necessary to detect robust differences in SP‐GCMs. These results emphasize that the properties of MCSs can vary widely across individual events, and improving their representation in global simulations with significant internal variability may require comparison to long (multidecadal) time series of observed events rather than single season field campaigns.

Published: April 2016

A 3D hierarchical porous catalyst architecture based on earth abundant metals Ni, Fe, and Co has been fabricated through a facile hydrothermal and electrodeposition method for efficient oxygen evolution reaction (OER) and hydrogen evolution reaction (HER). The electrode is comprised of three levels of porous structures including the bottom supermacroporous Ni foam (≈500 μm) substrate, the intermediate layer of vertically aligned macroporous NiCo2O4 nanoflakes (≈500 nm), and the topmost NiFe(oxy)hydroxide mesoporous nanosheets (≈5 nm). This hierarchical architecture is binder‐free and beneficial for exposing catalytic active sites, enhancing mass transport and accelerating dissipation of gases generated during water electrolysis. Serving as an anode catalyst, the designed hierarchical electrode displays excellent OER catalytic activity with an overpotential of 340 mV to achieve a high current density of 1200 mA cm−2. Serving as a cathode catalyst, the catalyst exhibits excellent performance toward HER with a moderate overpotential of 105 mV to deliver a current density of 10 mA cm−2. Serving as both anode and cathode catalysts in a two‐electrode water electrolysis system, the designed electrode only requires a potential of 1.67 V to deliver a current density of 10 mA cm−2 and exhibits excellent durability in prolonged bulk alkaline water electrolysis.
