Exploring the potential of SRTM topographic data for flood inundation modelling under uncertainty
Authors: Yan Kun , Di Baldassarre Giuliano , Solomatine Dimitri P.
Published: June 2013

The desirable data for model building and calibration to support the decision-making process in flood risk management are often not sufficient or unavailable. A potential opportunity is now offered by global remote sensing data, which can be freely (or at low cost) obtained from the internet, for example, Shuttle Radar Topography Mission (SRTM) topography. There is a general sense that inundation modelling performance will be degraded by using SRTM topography data. However, the actual effectiveness and usefulness of SRTM topography is still largely unexplored. To overcome this lack of knowledge, we have explored the value of SRTM topography to support flood inundation modelling under uncertainty. The study was performed on a 98 km reach of the River Po in northern Italy. The comparison between a hydraulic model based on high-quality topography and one based on SRTM topography was carried out by explicitly considering other sources of uncertainty (besides topography inaccuracy) that unavoidably affect hydraulic modelling, such as parameter and inflow uncertainties. The results of this study showed that the differences between the high-resolution topography-based model and the SRTM-based model are significant, but within the accuracy that is typically associated with large-scale flood studies.
Forecasting tropical cyclone intensity change in the western North Pacific
Authors: Lin Gwo-Fong , Huang Po-Kai , Lin Hsuan-Yu
Published: June 2013

For typhoon warning centers, effective forecasting of tropical cyclone intensity is always required. The major difficulties and challenges in forecasting tropical cyclone intensity are the complex physical mechanism and the structure of tropical cyclones. The interaction between the tropical cyclone and its environment is also a complex process. In this paper, a model based on support vector machines is developed to yield the 12, 24, 36, 48, 72 h forecasts of tropical cyclone intensity. Furthermore, the forecasts resulting from the proposed model are compared with those from the Joint Typhoon Warning Center. Cross-validation tests are also applied to evaluate the accuracy and the robustness of the proposed model. The results confirm that the proposed model can provide accurate forecasts of tropical cyclone intensity, especially for a long lead-time. When the sample events are classified into five categories according to the Saffir-Simpson scale, the forecasts resulting from the proposed model have the best performance for events in categories 4 and 5. In addition, when a typhoon turns northward, although the water temperature drops rapidly, the proposed model still performs well. In conclusion, the proposed model is useful to improve the forecasts of tropical cyclones intensity.
Factor Analysis of the Regulatory Emotional Self-efficacy Scale of Chinese College Students
Authors: Zhao Xiaojun , You Xuqun , Peng Zhengmin
Published: June 2013

In this study we assessed the regulatory emotional self-efficacy (RESE) of Chinese college students by collecting documentary resources and consulting relevant scales. The participants in the study were 927 college students from the provinces of Jiangsu, Guangdong, Anhui, and Gansu.
Exploratory factor analysis and confirmatory factor analysis were both applied in the scale analysis. The RESE scale of Chinese college students consisted of perceived self-efficacy in managing inferiority, happiness or contentment, envy, dread and fear, self-confidence, curiosity, and reliance.
The cross-validity of the scale was satisfied.
Is Incretin-Based Therapy Ready for the Care of Hospitalized Patients With Type 2 Diabetes?
Authors: Umpierrez Guillermo E. , Korytkowski Mary
Published: June 2013

Significant data suggest that overt hyperglycemia, either observed with or without a prior diagnosis of diabetes, contributes to an increase in mortality and morbidity in hospitalized patients. In this regard, goal-directed insulin therapy has remained as the standard of care for achieving and maintaining glycemic control in hospitalized patients with critical and noncritical illness. As such, protocols to assist in management of hyperglycemia in the inpatient setting have become commonplace in hospital settings. Clearly, insulin is a known entity, has been in clinical use for almost a century, and is effective. However, there are limitations to its use. Based on the observed mechanisms of action and efficacy, there has been a great interest in using incretin-based therapy with glucagon-like peptide-1 (GLP-1) receptor agonists instead of, or complementary to, an insulin-based approach to improve glycemic control in hospitalized, severely ill diabetic patients. To provide an understanding of both sides of the argument, we provide a discussion of this topic as part of this two-part point-counterpoint narrative. In the point narrative preceding the counterpoint narrative below, Drs. Schwartz and DeFronzo provide an opinion that now is the time to consider GLP-1 receptor agonists as a logical consideration for inpatient glycemic control. In the counterpoint narrative provided below, Drs. Umpierrez and Korytkowski provide a defense of insulin in the inpatient setting as the unquestioned gold standard for glycemic management in hospitalized settings.

Some aspects of the last glaciation in the Mazury Lake District (north-eastern Poland)
Authors: Pochocka-Szwarc Katarzyna
Published: June 2013

The morphology of the Mazury Lake District (north-eastern Poland) dates from 24-19 ka (main stadial of the youngest Vistulian glaciation). During this last glacial maximum (MIS 2) a belt with lacustrine basins was formed when the ice sheet retreated at the end of the Pomeranian phase. The ice-sheet retreat is morphologically also expressed by the occurrence of end moraines. The study area is situated in the Skaliska Basin, in the northern part of the Lake District (near the Polish/ Russian border), at the periphery of zone with end moraines. Originally the basin was an ice-dammed depression filled with melt water; the water flowed out into the developing Pregoła valley when the ice retreated and did no longer dam off the depression. The basin, which is surrounded by hill-shaped moraines, is filled now with Late Glacial and Holocene glaciolacustrine sediments. The organic sediments of the basin record the history of the Late Glacial and Holocene climatic changes in this region.
Depositional environment of a fan delta in a Vistulian proglacial lake (Skaliska Basin, north-eastern Poland)
Authors: Woronko Barbara , Pochocka-Szwarc Katarzyna
Published: June 2013

The study reconstructed the environment of a fan delta filling the vast end depression of the Skaliska Basin, and its overlying aeolian deposits. The formation of the large fan delta is associated with the presence of an ice-dammed lake functioning during the retreat of the Vistulian Glaciation (MIS 2). The examined material was collected from five boreholes. Sediments were analysed for their granulometric composition and subjected to analyses of frosting and rounding of quartz grains. Grain size analysis showed that the fan delta deposits are built of sand sediments of very low lateral and vertical variability. The fan delta was supplied with fluvioglacial sediments. Accumulation of sediments occurred in shallow water with a very low-gradient slope. The exposed fan delta became a site conducive to aeolian processes after the lake waters fell and the Skaliska Basin depression dried. Dune deposits overlying the fan were affected by short-distance transport so they did not acquire features typical for aeolian deposits.
The Late Glacial and Holocene development of vegetation in the area of a fossil lake in the Skaliska Basin (north-eastern Poland) inferred from pollen analysis and radiocarbon dating

Published: June 2013

The development of vegetation in the Skaliska Basin has been reconstructed on the basis of palynological analysis and radiocarbon dating (AMS technique) of 6 sites from the late phase of the Bolling- Allerod interstadial complex to modern times. Although the area covers 90 km2, the mosaic character of habitats led to the development of different patterns of vegetation changes during the Late Glacial and Holocene. Only one site located in the eastern part of the Skaliska Basin reflected the ‘pine phase’ of Allerod, and this is the oldest data on vegetation in the Skaliska Basin. Interesting discrepancies were recorded during the Younger Dryas when patches of shrublands with Juniperus were distinct around some of the sites, while steppe with Artemisia was common in others. The beginning of the Holocene brought an expansion of birch-pine forest, but around 9600 cal. BC a cold oscillation took place which was reflected in an increase in birch in the woodlands in the western and eastern part of the Skaliska Basin. In the Preboreal chronozone elm (Ulmus) also expanded in the area but its appearance was non-synchronous. The vegetation of the Boreal chronozone was similar in the whole area and the most characteristic feature was the rapid expansion of hazel (Corylus avellana) which displaced Betula from the most of its sites. At that time a distinct redeposition of pollen material in the Parchatka river valley was detected which was probably the effect of an increase in fluvial activity of the river (humid oscillation). The following stage of vegetation development was climax woodlands with Tilia cordata, Ulmus, Quercus, Corylus avellana, and Alnus in damp places. At the beginning of the Subboreal chronozone the expansion of Quercus took place, which was subsequently replaced by Picea abies and partly Carpinus betulus. The pattern of Picea abies expansion distinctly presents two maxima which is characteristic of many sites in the north-eastern Poland. The Subatlantic chronozone is represented only by the profile from the Skaliski Forest, where, because of sandy ground, Pinus sylvestris was the dominant element. Human impact was poorly reflected through the rare occurrence of pollen grains of Cerealia type in the pollen profiles spanning the time from the Subboreal chronozone to modern times. In most profiles AMS dating produced age discrepancies, which limited the possibility of establishment of a detailed chronology. However, dates obtained from the material contaminated by mixture of glycerine, thymol and ethyl alcohol, pretreated by alcohol, showed reliable results in most cases.

system, characterised by two unknown phases, and compare
the estimation precision achievable with two different strategies.
The first is a standard ‘joint estimation’ strategy, in which
a single probe state is used to estimate both parameters, while
the second is a ‘sequential’ strategy in which the two phases
are estimated separately, each on half of the total number of
system copies.
In the limit of small angles we show that, although the joint
estimation approach yields in general a better performance,
the two strategies possess the same scaling of the total phase
sensitivity with respect to the spin number j, namely ΔΦ≃ 1/j.
Finally, we discuss a simple estimation strategy based on spin
squeezed states and spin measurements, and compare its
performance with the ultimate limits to the estimation precision
that we have derived above.

Published: June 2013

We demonstrate high response organic ultraviolet photodetectors using 4,4′,4″-tris[3-methyl-pheny(phenyl)amino]tri-phenylamine (m-MTDATA) and two novel Cu(I) complexes, [Cu(DPEphos)(PyPhen)]BF4 (CuDP)(DPEphos = Bis [2-(diphenylphosphino)phenyl]ether, PyPhen = pyrazino[2,3-f][1,10]phenanthroline) and [Cu(DPEbenz)(PyPhen)]BF4 (CuBP) (DPEbenz = 1,2-bis(diphenylphosphino)benzene) to act as the electron donor and acceptor, respectively. Strong photoluminescence quenching of m-MTDATA by Cu(I) complexes is observed manifesting the efficient photoinduced charge transfer that occurs between m-MTDATA and Cu(I) complexes. The optimized photodetector based on CuBP exhibits a maximum response of 276 mA/W at −12 V under an illumination of 365 nm UV light irradiation with an intensity of 1.75 mW/cm2. The high response is attributed to feasible energy level match, efficient electron transfer from m-MTDATA to CuBP and skillful device design. More detailed working mechanism of harvesting high performance is also discussed.

Published: June 2013

The present investigation was conducted in the Agronomy field laboratory of Bangladesh Agricultural University, Mymensingh, Bangladesh during May 1999 to August 1999 to reveal the food and feeding habits of Amblypharyngodon mola in the rice field ecosystem. Percentage of frequency of occurrence and percentage in number methods were used for the qualitative and quantitative estimation of plankton population. Results showed that, during the present study, the water quality parameters were within the suitable range for optimal fish growth and plankton population was abundant in the water of the rice plots. Gut content analysis of A. mola revealed a sum of 32 genera of phytoplankton belonging to Chlorophyceae (17), Euglenophyceae (2), Cyanophyceae (7) and Bacillariophyceae (6) and 8 genera of zooplankton under Rotifera (3), Cladocera (2) and Copepoda (3). In general, Navicula, Fragilaria, Chlorella, Chrysococcus, Closterium, Oscillatoria and Gomphosphaeria were found abundant both in the water of the rice plots and in the gut contents of A. mola indicating that, these genera are preferred food of this fish in the rice field ecosystem. Gut content analysis also exposed that, phytoplankton was the major food item constituting 94.38% of the gut contents’ composition of A. mola whereas zooplankton comprised only 5.62%. The results of this study conclude that, the A. mola is planktivorous in nature, feeding mostly on phytoplankton and could be a suitable species for integrated rice-fish farming.DOI: http://dx.doi.org/10.3126/on.v11i1.8245 Our Nature Vol.11(1) 2013: 61-75
Neuroprotective Role of Nerve Growth Factor in Hypoxic-Ischemic Brain Injury
Authors: Fantacci Claudia , Capozzi Domenico , Ferrara Pietro , Chiaretti Antonio
Published: June 2013

Hypoxic-ischemic brain injuries (HIBI) in childhood are frequently associated with poor clinical and neurological outcome. Unfortunately, there is currently no effective therapy to restore neuronal loss and to determine substantial clinical improvement. Several neurotrophins, such as Nerve Growth Factor (NGF), Brain-Derived Neurotrophic Factor (BDNF), and Glial Derived Neurotrophic Factor (GDNF), play a key role in the development, differentiation, and survival of the neurons of the peripheral and central nervous system. Experimental animal studies demonstrated their neuroprotective role in HIBI, while only a few studies examined the neuroprotective mechanisms in patients with severe HIBI. We report two cases of children with HIBI and prolonged comatose state who showed a significant improvement after intraventricular NGF administration characterized by amelioration of electroencephalogram (EEG) and cerebral perfusion at single-photon emission computed tomography (SPECT). The improvement in motor and cognitive functions of these children could be related to the neuroprotective role exerted by NGF in residual viable cholinergic neurons, leading to the restoration of neuronal networks in the damaged brain.
Development of a Transient Model of a Stirling-Based CHP System
Authors: Ulloa Carlos , Míguez José , Porteiro Jacobo , Eguía Pablo , Cacabelos Antón
Published: June 2013

Although the Stirling engine was invented in 1816, this heat engine still continues to be investigated due to the variety of energy sources that can be used to power it (e.g., solar energy, fossil fuels, biomass, and geothermal energy). To study the performance of these machines, it is necessary to develop and simulate models under different operating conditions. In this paper, we present a one-dimensional dynamic model based on components from Trnsys: principally, a lumped mass and a heat exchanger. The resulting model is calibrated using GenOpt. Furthermore, the obtained model can be used to simulate the machine both under steady-state operation and during a transient response. The results provided by the simulations are compared with data measured in a Stirling engine that has been subjected to different operating conditions. This comparison shows good agreement, indicating that the model is an appropriate method for transient thermal simulations. This new proposed model requires few configuration parameters and is therefore easily adaptable to a wide range of commercial models of Stirling engines. A detailed analysis of the system results reveals that the power is directly related to the difference of temperatures between the hot and cold sources during the transient and steady-state processes.
The Progamic Phase in High-Mountain Plants: From Pollination to Fertilization in the Cold
Authors: Steinacher Gerlinde , Wagner Johanna
Published: June 2013

In high-mountains, cold spells can occur at any time during the growing season and plants may be covered with snow for several days. This raises the question to what extent sexual processes are impaired by low temperatures. We tested pollen performance and fertilization capacity of high-mountain species with different elevational distribution in the European Alps (Cerastium uniflorum, Gentianella germanica, Ranunculus glacialis, R. alpestris, Saxifraga bryoides, S. caesia, S. moschata) during simulated cold snaps in the laboratory. Plants were exposed to 0 °C (the temperature below the snow) for 12, 36, 60 and 84 h. In S. caesia, the experiment was verified in situ during a cold snap. Sexual processes coped well with large temperature differences and remained functional at near-freezing temperatures for a few days. During the cooling-down phase a high percentage (67–97%) of pollen grains germinated and grew tubes into the style. At zero degrees, tube growth continued slowly both in the laboratory and in situ below the snow. Fertilization occurred in up to 100% of flowers in the nival species and in G. germanica, but was strongly delayed or absent in the alpine species. During rewarming, fertilization continued. Overall, progamic processes in high-mountain plants appear fairly robust toward weather extremes increasing the probability of successful reproduction.
Understanding of Leaf Development—the Science of Complexity
Authors: Malinowski Robert
Published: June 2013

The leaf is the major organ involved in light perception and conversion of solar energy into organic carbon. In order to adapt to different natural habitats, plants have developed a variety of leaf forms, ranging from simple to compound, with various forms of dissection. Due to the enormous cellular complexity of leaves, understanding the mechanisms regulating development of these organs is difficult. In recent years there has been a dramatic increase in the use of technically advanced imaging techniques and computational modeling in studies of leaf development. Additionally, molecular tools for manipulation of morphogenesis were successfully used for in planta verification of developmental models. Results of these interdisciplinary studies show that global growth patterns influencing final leaf form are generated by cooperative action of genetic, biochemical, and biomechanical inputs. This review summarizes recent progress in integrative studies on leaf development and illustrates how intrinsic features of leaves (including their cellular complexity) influence the choice of experimental approach.
SPL8 Acts Together with the Brassinosteroid-Signaling Component BIM1 in Controlling Arabidopsis thaliana Male Fertility

Published: June 2013

The non-miR156 targeted SBP-box gene SQUAMOSA PROMOTER BINDING PROTEIN-LIKE 8 (SPL8), plays an important role in Arabidopsis anther development, where its loss-of-function results in a semi-sterile phenotype. Fully male-sterile plants are obtained when a spl8 loss-of-function mutation is introduced into a 35S:MIR156 genetic background, thereby revealing functional redundancy between SPL8 and miR156-targeted SBP-box genes. Here, we show that BIM1, a gene encoding a bHLH protein involved in brassinosteroid signaling and embryonic patterning, functions redundantly with SPL8 in its requirement for male fertility. Although bim1 single mutants displayed a mild fertility problem due to shortened filaments in some flowers, mutation of BIM1 significantly enhanced the semi-sterile phenotype of the spl8 mutant. Expression of both SPL8 and BIM1 was detected in overlapping expression domains during early anther developmental stages. Our data suggest that in regulating anther development, SPL8 and BIM1 function cooperatively in a common complex or in synergistic pathways. Phylogenetic analysis supports the idea of an evolutionary conserved function for both genes in angiosperm anther development.
Stop-and-Go Mode: Sensor Manipulation as Essential as Sensor Development in Terrestrial Laser Scanning
Authors: Lin Yi , Hyyppä Juha , Kukko Antero
Published: June 2013

This study was dedicated to illustrating the significance of sensor manipulation in the case of terrestrial laser scanning, which is a field now in quick development. In fact, this quickness was mainly rooted in the emergence of new sensors with better performance, while the implications of sensor manipulation have not been fully recognized by the whole community. For this technical gap, the stop-and-go mapping mode can be reckoned as one of the potential solution plans. Stop-and-go was first proposed to handle the low efficiency of traditional static terrestrial laser scanning, and then, it was re-emphasized to improve the stability of sample collections for the state-of-the-art technology of mobile laser scanning. This work reviewed the previous efforts of trying the stop-and-go mode for improving the performance of static and mobile terrestrial laser scanning and generalized their principles respectively. This work also analyzed its advantages compared to the fully-static and fully-kinematic terrestrial laser scanning, and suggested the plans with more automatic measures for raising the efficacy of terrestrial laser scanning. Overall, this literature review indicated that the stop-and-go mapping mode as a case with generic sense can verify the presumption of sensor manipulation as essential as sensor development.
Autobiographie et héritage dans la langue des dieux : d'Homère à Hésiode et Pindare (2e partie)
Authors: Bader Françoise
Published: June 2013

Pindare distribue entre ses deux exemples de la langue des dieux : a) la thématique de la langue des dieux hittite et de ses prédécesseurs grecs (Iliade, Odyssée, Hésiode), relative à : un microcosme qui comporte une anthropogonie (par naissance bisexuée) et une légitimité sociale fondée sur la famille, et figurée par les «concubines du dieu de l'orage» (en termes hittites) dont les errances-fixations en une île (terre dans les eaux comme l'embryon qu'elles portent en leur sein) sont homologuées à l'errance-fixation des terres ; et un cosmos qui comporte parallèlement une cosmogonie (dans laquelle l'errance-fixation de ces terres d'un sombre infernal s'oppose au ciel éternellement brillant du mouvement réglé des astres, avec, de plus, métaphore de la hutte cosmique, comme en Inde et Iran), ainsi qu'un dieu souverain légitime de l'ordre cosmique qui a été fondé ; b) les formulaires (relatifs à cette cosmogonie) hérités, et les innovations grecques que sont les mentions autobiographiques et les techniques formelles de récurrences lexicales et d'anagrammes.
La genèse de l'acte volontaire chez le héros homérique : les syntagmes d'incitation à l'action
Authors: Sautel Jacques-Hubert
Published: June 2013

Jacques-Hubert Sautei., Le héros homérique doit-il être compris comme ayant une personnalité unifiée ou éclatée en de multiples prises de consciences somatiques ? L'étude des syntagmes d'incitation à l'action, où un substantif désignant une instance psychique se trouve sujet d'un verbe de volonté ou d'un verbe employé métaphoriquement permet de donner une réponse partielle. Parmi les métaphores employées, l'une des plus intéressantes est celle de la parole imperative : on passe ainsi de l'injonction exprimée dans un groupe social (armée, maisonnée, société des dieux) à l'ordre intérieur que le héros reçoit de son θυμός ou de sa κραδίη. Une certaine organisation de l'univers psychique du héros semble ainsi se dégager.

Particularités et caractéristiques physiques, parfois défectueuses, sont, exprimées en grec ancien par des formations adjectivales diverses. Cependant le groupe des adjectifs oxytons, dissyllabiques en -σός (γαμψός, καμψός, ῥαμψός, γαυσός, βλαισός, φοξός, φριξός, ῥυσός, λοξός) constitue une série homogène à l'intérieur de laquelle s'opèrent des connexions. Ce micro-système lexical n'est cependant pas clos sur lui-même : il entretient des relations avec d'autres représentants du plus vaste champ sémantique auquel il appartient.

La fin de l'adolescence aujourd'hui
Authors: Ungar Virginia
Published: June 2013

L’auteur place l’adolescence dans un point de tension entre l’approche évolutive qui postule une séquence déjà prévue qui doit être accomplie nécessairement, et d’autres perspectives qui considèrent qu’il s’agit d’un état mental indépendant, d’une certaine manière, de l’âge. Pour étudier la fin de l’adolescence, l’auteur considère que dans l’actualité, époque de changements accélérés, il y a au moins trois facteurs qui affectent le parcours et la fin de l’adolescence de même que la pratique analytique quotidienne : la technologie et les médias, la sexualité et les nouvelles configurations familiales. Chacun de ces sujets est examiné séparément. La question de la fin d’analyse des patients adolescents est considérée dans une section à part.
Parentalité et fins de l'adolescence
Authors: Servant Benoît
Published: June 2013

La fonction parentale est présente à la fin d’adolescence à un double titre : du côté du thérapeute, dont la dimension parentale sublimée est relevée par différents auteurs, ce qui est ici illustré par des vignettes cliniques ; du côté de l’adolescent, dont l’entrée dans l’âge adulte est intimement liée à son accession à la capacité psychique de devenir parent, ce qui est également abordé dans la littérature, et illustré par l’auteur, en particulier pour des cas de fin d’adolescence différée. La fin d’adolescence est ainsi ce moment où le sujet est en mesure de reprendre à son compte ce qu’il a reçu pour le transmettre à son tour.

Comment finir l’adolescence quand on peine à y entrer ? Comment une équipe d’hôpital de jour se sépare-t-elle d’un jeune adulte qu’elle a suivi pendant des années ? À travers le cas de Juliette, jeune fille engluée dans ses résistances au changement et générant dans l’institution un sentiment d’impuissance identique à celui des parents, nous tenterons de montrer comment la limite posée à la prise en charge peut favoriser l’expression de certaines motions pulsionnelles jusque-là réprimées et permettre à un véritable processus maturatif de s’instaurer. Du côté de l’institution, il faudra renoncer aussi à une forme de toute-puissance pour laisser advenir le nouveau sujet dans sa singularité.
Approche historique du dépôt légal en France

Le dépôt légal, vieille institution créée en France par François I er en 1537, a été conçu à l’origine pour recueillir, dans la bibliothèque du roi – ancêtre de la Bibliothèque nationale – les livres imprimés en France. Au fur et à mesure que les techniques d’impression, plus largement de reproduction, non seulement des textes mais des documents, ont évolué, le dépôt légal a évolué lui aussi. Au fil des siècles, il a englobé les différents types de documents, au fur et à mesure de leur apparition, jusqu’aux documents numériques aujourd’hui. Il constitue donc un fondement essentiel pour la recherche historique, à cause précisément de cette complétude.

L'émergence et l'élaboration d'un patrimoine télévisuel en Méditerranée
Authors: Crivello Maryline
Published: June 2013

Des dispositifs internationaux tels que le Partenariat euroméditerranéen (PEM) ou l’Union pour la Méditerranée (UPM) ont cherché à défier les affrontements potentiels en Méditerranée. Par ailleurs, le rôle des médias et des réseaux sociaux n’a cessé de démontrer leur importance dans cette configuration, à la lumière, notamment, des récentes « révolutions arabes ». Dans ce contexte, deux projets de sauvegarde et de diffusion des archives audiovisuelles des télévisions nationales de la Méditerranée ont vu le jour grâce au PEM. Le projet Cap-Med (2000-2005) a permis de sauver les archives télévisuelles de douze pays méditerranéens menacées de disparition en raison de la dégradation des supports. Il a été nécessaire de les numériser pour les sauvegarder et les rendre accessibles dans les milieux professionnels. Le projet MedMem. Mémoires audiovisuelles en Méditerranée (2009-2013) visait, quant à lui, à constituer un site internet gratuit et éditorialisé à partir d’une sélection d’archives télévisuelles de pays méditerranéens. Par leur démarche, ces initiatives mettent en jeu l’émergence d’un espace politique méditerranéen et la prise de conscience d’un patrimoine télévisuel dans cet espace, mais participent également à la structuration des politiques et des études dites méditerranéennes.

Les enseignements les plus riches nous sont venus d’un séminaire de formation spécifiquement dédié aux archives sonores et largement fondé sur des exercices d’écoute. Le premier des enseignements est que la plupart de ces archives laissent croire aux auditeurs qu’elles sont immédiatement audibles. Le meilleur exemple, le plus célèbre, est celui de la grande Sarah, dont les enregistrements de Phèdre ont été souvent commentés. Les chercheurs les plus avisés mettent leur déception (fréquente) sur le compte du phonographe. En nous appuyant sur un corpus de phonogrammes théâtraux, nous nous intéresserons aux caractéristiques originales des documents audio, à leur double rapport intense et au passé et au présent, avant de proposer les règles d’une écoute historicisée.
Competency of New Graduate Nurses: A Review of Their Weaknesses and Strategies for Success
Authors: Theisen Janelle L. , Sandau Kristin E.
Published: June 2013

Because of the ongoing nursing shortage and the increasing acuity of patients, new graduate nurses must master both psychomotor and critical thinking skills rapidly. Inadequate orientation leads to high turnover rates for new graduates. Health care leaders must examine the competencies needed for new graduate nurses to succeed in this environment. A critical review of studies (
n
= 26) was conducted to identify crucial competencies that are needed for new graduate nurses to be successful. Six areas were identified in which new graduates lacked competence: communication, leadership, organization, critical thinking, specific situations, and stress management. Strategies were identified to improve the transition of new graduates. Hospitals should consider implementing nurse residency programs that include strategies for clear communication and conflict management, prioritization skills, and leadership development. Schools of nursing should add communication strategies to their current focus on critical thinking, clinical reasoning, and simulation scenarios and include situation-specific skills such as end-of-life scenarios. Further research should focus on stress management, leadership, clinical reasoning, and evaluation of measurement tools for new graduates.

Development of an Online Orientation Course for Preceptors in a Dedicated Education Unit Program
Authors: Krampe Jean , L’Ecuyer Kristine , Palmer Janice L.
Published: June 2013

The dedicated education unit (DEU) is an emerging model of nursing education. Instead of an instructor-led clinical group, students are partnered with a unit staff nurse for precepted learning. These experiences in learning typically begin with early clinical courses. Precepting nursing students in a DEU is different from precepting newly hired staff nurses and traditional clinical students. This article describes the DEU model implemented at one university, the challenges associated with preparing staff nurses to precept nursing students, the development of a face-to-face DEU preceptor orientation, and progression to an innovative online orientation course.

Patterns and Problems Associated with Transitions After Hip Fracture in Older Adults
Authors: Popejoy Lori L. , Dorman Marek Karen , Scott-Cawiezell Jill
Published: June 2013

This qualitative, descriptive, longitudinal, multiple case study describes the number and type of care transitions and problems experienced by 21 older urban and rural hip fracture patients in the year following hip fracture repair. Three patterns of transitions emerged: home to hospital to inpatient rehabilitation facility (
n
= 8); home to hospital to skilled nursing facility (SNF,
n
= 11); and intermediate nursing home to hospital to SNF (
n
= 2). Hip fracture patients experienced a median of 4 (range = 4 to 8) transitions in the year following repair. Problems common to all patterns were weight loss, delirium, depression, pressure ulcers, falls, and urinary incontinence. Patients newly admitted to SNFs experienced more problems and order discrepancies than those discharged to an inpatient rehabilitation facility. Families often identified problems first. Strategies to improve transitional care to older hip fracture patients should include improved patient and family involvement at the time of transition, irrespective of initial discharge location. [

Complications of Femtosecond Laser-Assisted Re-treatment for Residual Refractive Errors After LASIK
Authors: Vaddavalli Pravin K. , Diakonis Vasilios F. , Canto Ana P. , Culbertson William W. , Wang Jianhua , Kankariya Vardhaman P. , Yoo Sonia H.
Published: June 2013

PURPOSE:

To report complications of femtosecond laser-assisted re-treatment by the creation of side cuts within the old flaps for residual refractive error after primary LASIK in two patients.

METHODS:

Case report.

RESULTS:

Three eyes of two patients had complications with a circumferential sliver of stromal tissue displaced during surgery due to overlap of old and new side cuts. The displaced tissue was repositioned and corneal anatomy was restored. Two of three eyes demonstrated improvement in the uncorrected visual acuity, whereas one eye lost two lines of corrected visual acuity due to loss of tissue at side cut resulting from flap manipulation, which was done at 1 week.

CONCLUSIONS:

These cases demonstrate a complication of femtosecond laser-enabled side-cut for LASIK enhancement and factors that may lead to this complication and precautions to avoid it.

Relation of Helicobacter pylori infection and multiple sclerosis in Iranian patients
Authors: Mohebi Nafiseh , Mamarabadi Mansoureh , Moghaddasi Mehdi
Published: June 2013

Multiple sclerosis (MS) is the most prevalent central nervous system demyelinating disease. There are known risk factors for MS. However, there is uncertainty in its protective factors. Few studies have demonstrated that some chronic infections may have protective effects on this disease. We carried this study to investigate the relation between Helicobacter pylori (HP) infection and the prevalence and severity of MS. In this case-control study, 163 MS patients and 150 sex- and age- matched controls were included. Blood samples for IgG and IgM anti HP antibodies were collected from all individuals. Also, the Expanded Disability Status Scale (EDSS) was used to evaluate the MS patients. Suitable statistical analysis was applied. A Significant difference was observed in seropositivity between these two groups (P<0.001) but no significant difference was seen in seropositivity between conventional and opticospinal MS (P=0.522). No significant difference was observed in seropositivity among ages (P=0.075) and between genders (P=0.204). A significant difference was seen in EDSS value between seropositive and seronegative patients (P=0.017). We concluded that patients with HP infection had lower incidence of multiple sclerosis and MS patients with HP infection showed lower neurologic complications, which can demonstrate that HP infection may have a protective influence on MS pathogenesis.
The coexistence of multiple sclerosis and hereditary spastic paraparesis in a patient

Published: June 2013

Multiple sclerosis (MS) is a chronic disease characterized by multiple areas of central nervous system inflammation, demyelination and axonal loss. Hereditary spastic paraparesis (HSP) is characterized clinically by progressive spasticity and weakness of the lower limbs and pathologically by retrograd axonal degeneration of the corticospinal tracts and posterior columns. We identified a patient with clinical history and investigation findings consistent with the concurrence of both MS and HSP. Laboratory and radiological investigations, cognitive tests were performed. Genetic confirmation for spastin gene mutation has been completed. If this coexistence is not coincidence the mutation in the spastin gene may be a strong susceptibility locus for MS.

Preface
From 2003 to 2006, the Earth Sciences Sector of Natural Resources Canada conducted a study of the sensitivity of the Roberts Bank tidal flats and marsh to rising sea level, under the Climate Change Impacts and Adaptation Program (Project A600). The study was a multi-disciplinary effort involving
geologists, biologists and social scientists comprising a scientific study of the tidal flat environment and a stakeholder engagement process. The results of the work were presented at a Final Stakeholder Workshop on 24 March 2006 and compiled into a preliminary report distributed to the major
stakeholders.
Since that time, further research, particularly on global and local sea level rise has been carried out and published. The results presented in the draft report were based on the Intergovernmental Panel on Climate Change's Third Assessment Report. Since that time, the IPCC has published its Fourth
Assessment. The present report includes this new information. Where the results differ significantly from those presented in the draft report, this is noted directly in the text. Also, since 2006, several publications have validated the results presented in the draft report and references to these
publications are included in the present version. No further updates of the report are anticipated, but it should be understood that any projections of future conditions are subject to change as understanding of climate change evolves.
This Open File presents the scientific findings of the study and includes data sets that are not archived elsewhere. In addition, workshop reports and documents resulting from the stakeholder engagement process are included.

Cyclooxygenase (COX) plays a critical role in peptic ulcer development. COX-2 contains CpG islands in promoter area, which suggests possible epigenetic mechanisms of gene silencing. We evaluated COX-2 gene promoter methylation levels in the gastric mucosa of patients with various gastric diseases. DNA was extracted from endoscopic biopsy materials collected from the gastric mucosa. The methylation levels of the COX-2 gene promoter were measured quantitatively by using pyrosequencing. COX-2 mRNA expression in Kato III and AGS cells was measured using real-time PCR. COX-2 gene promoter methylation levels were significantly higher in Helicobacter pylori (HP)-positive cases than in HP-negative cases (27.5% vs. 8.1%, respectively, P < 0.001). COX-2 gene promoter methylation levels in patients in whom HP was successfully eradicated were significantly lower than those in HP-positive cases (18.7% vs. 27.5%, respectively, P < 0.01). We then investigated the effects of COX-2 gene promoter methylation on its mRNA expression in vitro. COX-2 mRNA expression was not observed in Kato III cells, despite the addition of the protein kinase C stimulator a-phorbol 12,13-dibutyrate (PDBu). COX-2 expression was observed after the addition of the demethylating agent 5-Aza-dC and was enhanced by PDBu. HP infection caused a significant increase in the methylation levels of the COX-2 gene promoter in the gastric mucosa. In addition to transcriptional regulation, COX-2 expression is regulated through epigenetic mechanisms.
