Temporal Variability of Land–Atmosphere Coupling and Its Implications for Drought over the Southeast United States
Authors: Roundy Joshua K. , Ferguson Craig R. , Wood Eric F. 
Published: November 2012

AbstractDroughts represent a significant source of social and economic damage in the southeast United States. Having sufficient warning of these extreme events enables managers to prepare for and potentially mitigate the severity of their impacts. A seasonal hydrologic forecast system can provide such warning, but current forecast skill is low during the convective season when precipitation is affected by regionally varying land surface heat flux contributions. Previous studies have classified regions into coupling regimes based on the tendency of surface soil moisture anomalies to trigger convective rainfall. Until now, these classifications have been aimed at assessing the long-term dominant feedback signal. Sufficient focus has not been placed on the temporal variability that underlies this signal. To better understand this aspect of coupling, a new classification methodology suitable at daily time scales is developed. The methodology is based on the joint probability space of surface soil moisture, convective triggering potential, and the low-level humidity index. The methodology is demonstrated over the U.S. Southeast using satellite remote sensing, reanalysis, and hydrological model data. The results show strong persistence in coupling events that is linked to the land surface state. A coupling-based drought index shows good agreement with the temporal and spatial variability of drought and highlights the role of coupling in drought recovery. The implications of the findings for drought and forecasting are discussed.
A Long-Term, High-Resolution Wetland Dataset over the Amazon Basin, Downscaled from a Multiwavelength Retrieval Using SAR Data
Authors: Aires Filipe , Papa Fabrice , Prigent Catherine 
Published: November 2012

AbstractA climatology of wetlands has been derived at a low spatial resolution (0.25° × 0.25° equal-area grid) over a 15-yr period by combining visible and near-infrared satellite observations and passive and active microwaves. The objective of this study is to develop a downscaling technique able to retrieve wetland estimations at a higher spatial resolution (about 500 m). The proposed method uses an image-processing technique applied to synthetic aperture radar (SAR) information about the low and high wetland season. This method is tested over the densely vegetated basin of the Amazon. The downscaling results are satisfactory since they respect the spatial hydrological features of the SAR data and the temporal evolution of the low-resolution wetland estimates. A new long-term and high-resolution wetland dataset has been generated for 1993–2007 for the Amazon basin. This dataset represents a new and unprecedented source of information for climate and land surface modeling of the Amazon and for the definition of future hydrology-oriented satellite missions such as Surface Water and Ocean Topography (SWOT).
Radar Data Assimilation with WRF 4D-Var. Part II: Comparison with 3D-Var for a Squall Line over the U.S. Great Plains
Authors: Sun Juanzhen , Wang Hongli 
Published: November 2012

Abstract
The Weather Research and Forecasting Model (WRF) four-dimensional variational data assimilation (4D-Var) system described in Part I of this study is compared with its corresponding three-dimensional variational data assimilation (3D-Var) system using a Great Plains squall line observed during the International H2O Project. Two 3D-Var schemes are used in the comparison: a standard 3D-Var radar data assimilation (DA) that is the same as the 4D-Var except for the exclusion of the constraining dynamical model and an enhanced 3D-Var that includes a scheme to assimilate an estimated in-cloud humidity field. The comparison is made by verifying their skills in 0–6-h quantitative precipitation forecast (QPF) against stage-IV analysis, as well as in wind forecasts against radial velocity observations. The relative impacts of assimilating radial velocity and reflectivity on QPF are also compared between the 4D-Var and 3D-Var by conducting data-denial experiments. The results indicate that 4D-Var substantially improves the QPF skill over the standard 3D-Var for the entire 6-h forecast range and over the enhanced 3D-Var for most forecast hours. Radial velocity has a larger impact relative to reflectivity in 4D-Var than in 3D-Var in the first 3 h because of a quicker precipitation spinup. The analyses and forecasts from the 4D-Var and 3D-Var schemes are further compared by examining the meridional wind, horizontal convergence, low-level cold pool, and midlevel temperature perturbation, using analyses from the Variational Doppler Radar Analysis System (VDRAS) as references. The diagnoses of these fields suggest that the 4D-Var analyzes the low-level cold pool, its leading edge convergence, and midlevel latent heating in closer resemblance to the VDRAS analyses than the 3D-Var schemes.

Published: November 2012

Abstract

Background
The morphogenesis of herpes simplex virus type 1 (HSV-1) comprises several events, of which some are not completely understood. It has been shown that HSV-1 glycoproteins accumulate in the trans-Golgi network (TGN) and in TGN-derived vesicles. It is also accepted that HSV-1 acquires its final morphology through a secondary envelopment by budding into TGN-derived vesicles coated with viral glycoproteins and tegument proteins. Nevertheless, several aspects of this process remain elusive. The small GTPase Rab27a has been implicated in regulated exocytosis, and it seems to play a key role in certain membrane trafficking events. Rab27a also seems to be required for human cytomegalovirus assembly. However, despite the involvement of various Rab GTPases in HSV-1 envelopment, there is, to date, no data reported on the role of Rab27a in HSV-1 infection.

Results
Herein, we show that Rab27a colocalized with GHSV-UL46, a tegument-tagged green fluorescent protein-HSV-1, in the TGN. In fact, this small GTPase colocalized with viral glycoproteins gH and gD in that compartment. Functional analysis through Rab27a depletion showed a significant decrease in the number of infected cells and viral production in Rab27a-silenced cells.

Conclusions
Altogether, our results indicate that Rab27a plays an important role in HSV-1 infection of oligodendrocytic cells.

Published: November 2012

Abstract

Background
Diet quality tools have been developed to assess the adequacy of dietary patterns for predicting future morbidity and mortality. This study describes the development and evaluation of a brief food-based diet quality index for use with children at the individual or population level. The Australian Child and Adolescent Recommended Food Score (ACARFS) was developed to reflect adherence to the Dietary Guidelines for Children and Adolescents in Australia and modelled on the approach of the US Recommended Food Score.

Methods
The ACARFS has eight sub-scales and is scored from zero to 73. The diet quality score was evaluated by assessing correlation (Spearman’s correlations) and agreement (weighted κ statistics) between ACARFS scores and nutrient intakes, derived from a food frequency questionnaire in 691 children (mean age 11.0, SD 1.1) in New South Wales, Australia. Nutrient intakes for ACARFS quartiles were compared with the relevant Australian nutrient reference values.

Results
ACARFS showed slight to substantial agreement (κ 0.13-0.64) with nutrient intakes, with statistically significant moderate to strong positive correlations with all vitamins, minerals and energy intake (r = 0.42-0.70). ACARFS was not related to BMI.Participants who scored less than the median ACARFS were more likely to have sub-optimal intakes of fibre, folic acid and calcium.

Conclusion
ACARFS demonstrated sufficient accuracy for use in future studies evaluating diet quality. Future research on its utility in targeting improvements in the nutritional quality of usual eating habits of children and adolescents is warranted.

Abstract

Background
Replication and transcription, the two key functions of DNA, require unwinding of the DNA double helix. It has been shown that replication origins in the budding yeast, Saccharomyces cerevisiae contain an easily unwound stretch of DNA. We have used a recently developed method for determining the locations and degrees of stress-induced duplex destabilization (SIDD) for all the reported replication origins in the genome of the fission yeast, Schizosaccharomyces pombe.

Results
We have found that the origins are more susceptible to SIDD as compared to the non-origin intergenic regions (NOIRs) and genes. SIDD analysis of many known origins in other eukaryotes suggests that SIDD is a common property of replication origins. Interestingly, the previously shown deletion-dependent changes in the activities of the origins of the ura4 origin region on chromosome 3 are paralleled by changes in SIDD properties, suggesting SIDD’s role in origin activity. SIDD profiling following in silico deletions of some origins suggests that many of the closely spaced S. pombe origins could be clusters of two or three weak origins, similar to the ura4 origin region.

Conclusion
SIDD appears to be a highly conserved, functionally important property of replication origins in S. pombe and other organisms. The distinctly low SIDD scores of origins and the long range effects of genetic alterations on SIDD properties provide a unique predictive potential to the SIDD analysis. This could be used in exploring different aspects of structural and functional organization of origins including interactions between closely spaced origins.

Abstract
Isolation of polyhydroxyalkanoates (PHAs) from bacterial cell matter is a critical step in order to achieve a profitable production of the polymer. Therefore, an extraction method must lead to a high recovery of a pure product at low costs. This study presents a simplified method for large scale poly(3-hydroxybutyrate), poly(3HB), extraction using sodium hypochlorite. Poly(3HB) was extracted from cells of Ralstonia eutropha H16 at almost 96% purity. At different extraction volumes, a maximum recovery rate of 91.32% was obtained. At the largest extraction volume of 50 L, poly(3HB) with an average purity of 93.32% ± 4.62% was extracted with a maximum recovery of 87.03% of the initial poly(3HB) content. This process is easy to handle and requires less efforts than previously described processes.

ABSTRACT

Objective:
To evaluate the impact of the incisor position on the self-perceived psychosocial impacts of malocclusion among Chinese young adults.

Materials and Methods:
This cross-sectional study included a convenience sample of 17.1- to 22.3-year-old young adults (n  =  1005). The five groups represented were normal occlusion as well as incisor Class I, Class II/1, Class II/2, and Class III malocclusion. For clinical assessment, the incisor relationship was evaluated according to the British Standards Institute Incisor Classification, and the self-perception of dental esthetics was assessed using the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ). Statistical analysis involved the analysis of variance and Tukey multiple-comparison post hoc tests.

Results:
Psychosocial impacts were different among the five groups for the four PIDAQ domains (P &lt; .001 for all four domains). Statistically significant differences were found between the four malocclusion groups and the normal occlusion group in all four domains (P &lt; .001 for all four domains). Furthermore, statistically significant differences were found between four malocclusion groups.

Conclusions:
All four malocclusion groups had more severe psychosocial impacts than the normal occlusion group in the four PIDAQ domains. Statistically significant differences were also found between the four malocclusion groups; these malocclusion groups ranked by score, highest to lowest, were Class III, Class II/1, Class II/2, and Class I.
La fin de la télévision ?
Authors: Beuscart Jean-Samuel , Beauvisage Thomas , Maillard Sisley 
Published: November 2012

Résumé L’offre de rattrapage a multiplié les possibilités, pour le téléspectateur, de consommer les programmes télévisés « où il veut, quand il veut ». Pour certains analystes, cette évolution précipite « la fin de la télévision », conçue comme le fait pour une audience dispersée de regarder le même programme au même moment. Nous étudions empiriquement ce phénomène à partir des données d’audiences journalières de l’ensemble des programmes proposés en rattrapage sur le Web par les chaînes françaises. Nous observons que, contrairement à ce que suppose la théorie de la « longue traîne », les audiences sont plus concentrées sur le Web que sur le flux télévisé, et que la consommation à la demande reste majoritairement attachée à la temporalité fixée par les chaînes. Ainsi, la consommation à la demande n’annule pas la capacité de la télévision à réunir des audiences pour partager des contenus.
Les productions audiovisuelles des joueurs de jeux vidéo
Authors: Auray Nicolas , Georges Fanny 
Published: November 2012

Résumé L’article vise à étudier la place des créations filmiques fabriquées par des joueurs de jeu vidéo. L’objectif est de replacer l’étude des modes de consécration artistique et de quelques trajectoires de professionnalisation de ces jeunes auteurs dans le contexte plus large d’une construction progressive du jeu vidéo comme un espace culturel qui s’est différencié par rapport au cinéma. Dans un tel contexte de spécialisation professionnelle, les créations filmiques faites à partir de moteurs de jeu ont un rôle de « passerelles » entre les deux médias, permettant aux passionnés du jeu vidéo qui se destinent à des carrières professionnelles l’apprentissage des grammaires esthétiques du cinéma. Dans un contexte d’industrialisation du jeu vidéo et de spécialisation des formations professionnelles, le rôle de ces apprentissages esthétiques autodidactes s’est paradoxalement accru.
Défense de la diversité culturelle : variété ou dialogue ?
Authors: Gensollen Michel 
Published: November 2012

Résumé L’industrialisation des biens culturels a concentré la production mondiale aux États-Unis (en particulier dans le cas du cinéma). Il est espéré aujourd’hui que la numérisation et la mise en réseau des informations pourra contrebalancer une telle tendance en réduisant les coûts de promotion et de distribution (longue traîne). La diversité des expressions culturelles reste toutefois un objectif essentiel de la politique culturelle pour au moins trois raisons. (1) Les marchés des biens culturels sont de plus en plus imparfaits (biens d’expérience, biens tutélaires, externalités, économies d’échelle, ...) et doivent être régulés. (2) La culture ne se confond pas avec le divertissement individuel : il s’agit d’une consommation collective qui conditionne la construction identitaire des collectivités. (3) La qualité esthétique des œuvres permet, au-delà de la diversité, le dialogue entre les cultures, ce qui est le deuxième objectif fixé par la Convention de l’UNESCO de 2005 sur la protection et la promotion de la diversité des expressions culturelles.
Regard clinique sur le travail des auxiliaires de vie
Authors: Bardot Fabienne 
Published: November 2012

Résumé Le métier d’auxiliaire de vie est l’un des « serpents de mer » de la médecine du travail, car il est réputé comme un travail particulièrement usant. Les médecins du travail l’abordent le plus fréquemment par des descriptions chiffrées de liens santé-travail, mais butent sans cesse sur les actions de transformation. Dans cet article, une approche délibérément opposée est présentée. L’auteure décrit le cheminement de sa réflexion et de sa pratique pour aborder le travail de ces personnels d’un point de vue strictement clinique, jamais hygiéniste. Cette démarche s’est construite à partir des connaissances issues des consultations médicales pour s’appuyer finalement sur les débats collectifs autour du métier d’auxiliaire. L’auteure montre ce que ce mode de socialisation peut apporter du côté des règles de métier et des défenses collectives ainsi qu’en termes de possibilités d’accès à certains liens qui pourraient avoir des effets apaisants sur la santé.

Résumé L’objectif de cet article est d’analyser le travail de « care » auprès de personnes âgées, dans le contexte de travailleuses péruviennes ayant migré à Buenos Aires et travaillant à demeure. Il s’agit de situations fortement marquées par des relations interpersonnelles et un engagement subjectif particulièrement intenses. La première partie est consacrée à la présentation générale de la situation de ces travailleuses devenues « cuidadoras » à Buenos Aires. Dans la deuxième partie, l’analyse porte sur quelques éléments essentiels qui structurent la réalité quotidienne des « cuidadoras » à demeure, tels l’enfermement continu et l’intimité persistante avec des personnes très dépendantes. L’article s’achève sur une réflexion concernant les rôles ambigus de l’attachement affectif. L’ensemble des analyses prend appui sur des entretiens biographiques menés auprès des travailleuses.
Intraoperative Prognostic Factors for Probing Outcome in Children with Congenital Nasolacrimal Duct Obstruction
Authors: Andalib Dima , Nabei Reza 
Published: November 2012

Purpose To evaluate the intraoperative prognostic factors for probing outcome in children with congenital nasolacrimal duct obstruction (CNLDO). Methods In a prospective interventional study, 69 eyes of 60 children aged 12 to 24 months with CNLDO underwent probing and irrigation. All procedures were performed by a single oculoplastic surgeon. The nature of the obstruction was classified by the surgeon as simple or complex. The fluency of irrigation after probing was defined as easy or difficult. Treatment success was defined as no epiphora or mucus discharge at 3 months after probing. Results The mean age at the time of probing was 15.3±3.1 months (range, 12–23 months). Treatment success was achieved in 56 of 69 eyes (81.2%). There was a significant difference in success rate of probing in eyes with simple obstruction (87.8%) compared with complex obstruction (65%) (p=0.02). Also, there was a significant difference in success rate of probing in eyes with easy irrigation (100%) compared with difficult irrigation (53.6%) (p<0.001). Conclusions Probing was more successful in eyes with simple obstruction or easy irrigation in children aged 12 to 24 months. The fluency of irrigation as an objective finding was a reliable intraoperative prognostic factor for probing success.

Published: November 2012

Background Cryptotia is a congenital ear deformity in which the upper pole appears buried beneath the mastoid skin. Cryptotia is a common auricular malformation among Asians. The aim of this paper is to examine the surgical techniques for and complications of 34 cryptotic patients.
Methods Surgery was performed for 34 cryptotic deformities (January 2005 to January 2012). Twenty-two patients (64.7%) were classified as having type I cryptotia, and 12 patients (37.5%) type II cryptotia. Among the type I cryptotia patients, 8 patients had mild deformity and 14 severe deformity. Among the type II cryptotia patients, 10 patients had mild deformity and 2 severe deformity.
Results The mild deformities were corrected via Z-plasty, V-Y plasty, full-thickness skin graft, and transposition flap, while the severe deformities were corrected via cartilage graft or Medporfor the spread of cartilage adhesion of antihelix. There were two cases of reinvagination in the autologous cartilage graft group. Implant exposure occurred with Medpor (two cases). There were two cases of hypertrophic scar on the previous surgical wound with Medpor. There were no complications in the 18 patients who had mild deformities.
Conclusions The type I cryptotia patients had more severe deformities than the type II cryptotia patients. As most of the type II cryptotia patients had only mild deformities, their deformities were corrected without using autologous conchal cartilage graft or Medpor, except for two patients. Through more case analyses, researchers should make an effort to identify methods for recurrence and prevention of complication.
