El paro como equilibrio de flujo : los modelos de emparejamiento,
por François Langot, Isabelle Lebon.

El incremento de la duración promedio del paro en los principales países europeos ha incitado a los economistas a desarrollar modelos dinámicos, en los que la duración del paro es endógena. El objetivo de este artículo es el de mostrar cómo un estudio en términos de flujo en el mercado del trabajo permite analizar la persistencia del paro. Esta modelización da un fundamento microeconómico a las curvas de Beveridge y de Phillips, y demuestra su complementariedad en el anóáisis de la dinámica del paro. Este enfoque del mercado del trabajo puede integrarse en trabajos que demuestran la existencia de equilibrios múltiples o que aclaran la relación entre crecimiento y paro.
Décorations murales de Nîmes romaine
Authors: Sabrié Maryse , Sabrié Raymond 
Published: July 2011

Cet article présente un bilan provisoire et constitue une première approche de la peinture d'époque romaine à Nîmes. Basé sur l'étude de trouvailles anciennes et de découvertes récentes datées par les fouilles, il donne un aperçu du décor mural au cours des deux premiers siècles de notre ère.
Le site dit « les Jardins de l'Empereur » a livré une peinture de la seconde génération du IIe style provincial, que la datation directe situe au plus tard au début du Ier siècle. Elle présente des architectures fictives avec des panneaux rouge cinabre, diverses imitations de marbre et de minces consoles en esse. La période du IIIe style est représentée par des fragments du fonds ancien du Musée. L'influence de la mode provinciale apparaît dans les candélabres à ombelles ornés de rinceaux. Le système à panneaux hérité du IVe style se manifeste dans des versions assez simples faisant appel aux bordures ajourées ou aux candélabres. Occupé dans l'Antiquité par un quartier populaire, le terrain dit « Propriété Solignac » a fourni un ensemble de décors modestes de la première moitié du IIe s. La décoration la plus élégante provient d'une riche maison de la rue Pasteur. Exécutée vers le milieu du IIe siècle, période de splendeur pour la ville de Nîmes, cette peinture reflète les modes venues de la métropole. On y retrouve certains poncifs issus du répertoire de l'époque augustéenne.
Un trésor monétaire du IIIe s. ap. J.-C. découvert en 1883 à Cimiez (Nice)
Authors: Perez Florence 
Published: July 2011

Découvert en 1883 à Cimiez (Nice), le « trésor de la Compagnie des Eaux » compte aujourd'hui 289 antoniniani conservés au Musée Archéologique de Cimiez.
Ce petit pécule comprend des monnaies émises de Gordien III à Salonin César; il aurait été constitué peu après 259; si la production de l'atelier monétaire romain est prépondérante, la majorité des ateliers ayant fonctionné pendant cette période est représentée.
En annexe, nous proposons un inventaire provisoire (d'après les publications, d'un niveau très inégal) des trésors antiques découverts dans les Alpes-Maritimes.
Les cadastres antiques de la cité de Béziers. Systèmes inédits et problèmes de chronologie
Authors: Pérez Antoine N. 
Published: July 2011

When establishing a model for a geometric construction of Roman cadastrations, starting from one road (in this case the via Domitia), we were led to identify two centuriations never mentioned before, in the Béziers-Agde area. One of them, "Béziers E", in so far as orientation and metrology are concerned merges with the Greek cadastration of Agde, whose importance was overestimated by its discoverers. Therefore, besides the fact that the territory of the Chora of Agde is cut down to size, the underscoring of these two new cadastres — which increases up to six the number of ancient structures found in the Ager Baeterrensium — brings several new pieces of information on the following points:
— the birth and the forms of the materialization of a Roman cadastre;
— the relative chronology of the cadastral structures in the Languedoc;
— the types of relationships between Rome and Marseilles during the 1st century B.C. through the study of the lower part of the Hérault valley.
As a general rule, this article demonstrates the definite need of drawing up an exhaustive corpus of the ancient cadastres of the area, which is the only possible prerequisite in order to set up a global explaining scheme of the Roman colonial settlement in southern Gaul.

The hoard of Avressieux (Savoie) is discovered in 1885, consisting in about 3500 to 5000 antoniniani ranging from Valerian to Probus. 542 specimens were examined at the Musée Savoisien of Chambery and studied by C. Laffin, whose work was supervised, at the University of Savoie, by B. Rémy and M. Amandry, assisted of D. Hollard and S. Estiot.
Previous to the publication of C. Laffin's catalogue, 5 coins are studied here (2 Postumus, 2 Claudius and 1 Aurelian), as they deserve a particular attention.
Limitations antiques et morphologie parcellaire dans le Lunellois (Hérault) : données de fouilles récentes
Authors: Favory François , Malvis Jean-Michel , Mercier Catherine , Raynaud Claude , Roger Karine 
Published: July 2011

The plain of Lunel and Mauguio has been intensively prospected since 1986. The results of this investigation have allowed to obtain an archeological map listing, on the one hand more than 200 sites which have been identified as settlements, and on the other hand land manure spreading zones which were occupied during Antiquity and early Middle Ages.
Moreover, the work of the GdR 926 of Besançon established that several centuriations of Nîmes have marked the rural morphology of the region.
Excavations have been carried out on the site of the ancient village of Lunel Viel and on different sites discovered during the prospecting, such as the sites dating back to the late Antiquity and early Middle Ages in Dassargues and the one of the Lanes — Lunel — , the site of the Plantiers — Mudaison — or in the surroundings of the Via Domitia — Saturargues — . During these excavations, the team has succeeded in excavating and studying the remains of the parcels — dug limits, exploitation paths, walls of terrace — respecting the incline of one or another of the regional centuriations. Moreover these excavations have revealed other agricultural installations such as transplantation zones, storage zones with dolium or silos, cultivation ditches dug in the carbonated layer of the soil.

Background In haematopoietic stem cell transplant (HSCT) recipients, cytomegalovirus (CMV) infection contributes significantly to morbidity and mortality in both the early and late post-transplant period. Ganciclovir (GCV) is the treatment of choice for CMV, but requires intravenous administration, a fact that complicates its long-term use. Oral valganciclovir (VGCV) and intravenous GCV were recently shown to have similar efficacy for pre-emptive CMV treatment in solid organ transplant recipients, but relatively limited data are available in HSCT recipients. The objectives of this study were to compare the efficacy of VGCV versus intravenous GCV or foscarnet (FOS) for pre-emptive therapy of active CMV infection in allogeneic HSCT and to determine the incidence of adverse effects and relapses. Methods This was a 2-year prospective, comparative cohort study in which 237 episodes of pre-emptive therapy for active CMV infection were collected in 166 allogeneic HSCT recipients out of 717 included in the Spanish Network for Research on Infection in Transplantation (RESITRA/REIPI) database. Intravenous GCV was the first-line treatment in 112 episodes, intravenous FOS in 38 episodes, and oral VGCV in 87 episodes. Results VGCV was used as pre-emptive therapy for active CMV infection in 87 episodes. Excluding episodes considered as relapse, VGCV was as successful (91.4% [74/81]) as GCV (83.7% [87/14]) or FOS (75.8% [25/33]). In the VGCV arm, 7 (8.6%) cases were considered treatment failures: 4 (4.9%) because of adverse events, 1 (1.2%) due to persistent viral activity and 2 (2.5%) based on clinical decision. There were also 6 (7.4%) cases of recurrent infection. No statistically significant differences were found when compared to GCV or FOS. Conclusions In allogeneic HSCT recipients, VGCV seemed effective and safe in the pre-emptive therapy of active CMV infection.

Published: July 2011

Background and Objective Both extraocular muscle (EOM) and orbital fat are involved in Graves’ orbitopathy (GO) but their enlargement might occur with a different temporal pattern. Two GO subtypes have been described, one with predominant EOM enlargement and the other with prevalent fat tissue involvement. We longitudinally investigated the EOM in patients with GO and their relationship with clinical activity. Patients and Methods By using commercial software with a segmentation technique, we calculated from computed tomography (CT) scan EOM coronal area (CA) and total orbit coronal area (TOA) in 23 control subjects and in 32 patients with GO. The latter were studied both at presentation and 18 months later. Superior, lateral, inferior, and medial EOM areas and TOA were selected by 3 different contiguous CT slices: A, B, and C, chosen at globe pole tangent and 2 and 4 mm backward. The Clinical Activity Score (CAS) was also measured. Results Orbital EOM CA/TOA ratio (OM/TOA ratio) after 18 months decreased in most patients with GO, indicating that EOM area decrement contributed significantly to OM/TOA ratio reduction. Clinical Activity Score decrease was significantly correlated to the OM/TOA ratio decrease. Conclusions An easy method to measure CA of EOM and orbit allowed us to observe that in most patients with GO the OM/TOA ratio decreases with time, suggesting that macroscopic EOM involvement occurs initially and resolves as the other clinical signs and symptoms of the disease resolve, as indicated by the significant OM/TOA ratio correlation with CAS.
Survivorship navigation outcome measures

Published: July 2011

AbstractSurvivorship navigation is a relatively new concept in the field of patient navigation but an important one. This article highlights the essential functions of the survivorship navigator and defines core outcomes and measures for navigation in the survivorship period. Barriers to access to care experienced by patients during active cancer treatment can continue into the post‐treatment period, affecting quality follow‐up care for survivors. These barriers to care can be particularly acute for non‐English speakers, immigrants, the uninsured, the underinsured, and other vulnerable populations. The survivorship navigator can help reduce barriers and facilitate access to survivorship care and services through communication and information exchange for patients. Survivorship navigation may improve appropriate health care utilization through education and care coordination, potentially improving health outcomes and quality of life of survivors while reducing cost to the health care system. Survivorship navigators can also educate survivors on how to improve their overall wellness, thereby directly impacting the health of a growing population of cancer survivors.

Published: July 2011

AbstractBACKGROUND.The lack of comparable metrics to evaluate prevention and early detection patient navigation programs impeded the ability to identify best practices.METHODS.The Prevention and Early Detection Workgroup of the Patient Navigation Leadership Summit was charged with making recommendations for common clinical metrics specific to the prevention and early detection phase of the cancer care continuum. The workgroup began with a review of existing literature to characterize variability in published navigation metrics; then developed a list of priority recommendations that would be applicable to the range of navigation settings (clinical, academic, or community‐based).RESULTS.Recommendations for researchers and program evaluators included the following: 1) Clearly document key program characteristics; 2) Use a set of core data elements to form the basis of your reported metrics; and 3) Prioritize data collection using methods with the least amount of bias.CONCLUSIONS.If navigation programs explicitly state the context of their evaluation and choose from among the common set of data elements, meaningful comparisons among existing programs should be feasible.

Analytic element modelling for strip aquifers
Authors: Batista José Anderson N. , Wendland Edson , Schulz Harry E. 
Published: July 2011

AbstractThe Analytic Element Method (AEM) provides a convenient tool for groundwater flow analysis in unbounded continuous domains. The AEM is based on the superposition of analytic functions, known as elements, useful at both regional and local scales. In this study, analytic elements for strip aquifers are presented. Such aquifers occur in riverine or coastal deposits and in outcrop zones of confined aquifers. Local flow field is modelled indirectly, using a reference plane related to the aquifer domain through the Schwarz‐Christoffel transform. The regional flow is obtained as a solution of the one‐dimensional flow equation. The proposed methodology was tested by modelling two hypothetical situations, which were compared to exact solutions. It is shown that regional boundaries can be reproduced exactly while local fields are adequately reproduced with analytic elements. The developed elements are applied to simulate a real flow field in northeastern Brazil showing good agreement with measured water levels. Copyright © 2011 John Wiley & Sons, Ltd.
Comparison of cranial form and function in association with diet in natricine snakes
Authors: Hampton Paul M. 
Published: July 2011

AbstractThe skull of squamates has many functions, with food acquisition and ingestion being paramount. Snakes vary interspecifically in the frequency, size, and types of prey that are consumed. Natural selection should favor phenotypes that minimize the costs of energy acquisition; therefore, trophic morphology should reflect a snake's primary prey type to enhance some aspect of feeding performance. I measured 19 cranial variables for six natricine species that vary in the frequency with which they consume frogs and fish. Both conventional and phylogenetically corrected analyses indicated that fish‐eating snakes have relatively longer upper and lower jaw elements than frog‐eating snakes, which tended to have broader skull components. I also compared the ratio of the in‐lever to the out‐lever lengths of the jaw‐closing mechanism [jaw mechanical advantage (MA)] among species. Fish‐eating snakes had significantly lower MAs in the jaws than did the frog‐eating snakes. This result suggests that piscivores have faster closing jaws and that the jaws of frog‐eating snakes have higher closing forces. Cranial morphology and the functional demands of prey capture and ingestion appear to be associated with primary prey type in natricine snakes. J. Morphol., 2011. © 2011 Wiley‐Liss, Inc.

Published: July 2011

AbstractBackgroundThe current management of choledocholithiasis remains a controversial topic. Popular options for treatment include preoperative endoscopic retrograde cholangiopancreatography (ERCP) with endoscopic sphincterotomy (EST) followed by laparoscopic cholecystectomy (LC), or LC and laparoscopic common bile duct exploration (LCBDE) with T‐tube decompression. Some concerns suggest that sphincterotomy has significant long‐term complications as a result of sphincter of Oddi (SO) dysfunction, and T‐tube decompression is historically associated with many complications and discomfort. The purpose of this study was to demonstrate our simple, safe techniques of LCBDE without a T‐tube and with an intact SO.MethodsBetween April 2006 and July 2009, a total of 44 selected patients with common bile duct (CBD) stones underwent laparoscopic exploration at our institution. Of 44 laparoscopic choledochotomies, primary choledochorrhaphy was performed on patients with preoperatively installed endoscopic retrograde biliary drainage (ERBD) tubes (n = 10, 22.73%) or endonasobiliary drainage (ENBD) tubes (n = 10, 22.73%) and on patients with intraoperative biliary drainage C‐tubes (n = 9, 20.45%) or pigtail J biliary drainage tubes (n = 15, 34.09%).ResultsThe mean operating time for the ENBD, ERBD, J‐tube, and C‐tube groups were 97.8, 96.2, 102.1, and 98.7 min, respectively. There were no conversions to open surgery, and no intraoperative complications were experienced in any group. CBD clearance was achieved in 43 patients (97.73%). The mean lengths of follow‐up for the ENBD, ERBD, J‐tube, and C‐tube groups were 27.0, 26.7, 23.8, and 30.4 months, respectively; and none of the patients developed major biliary complications including recurrent stones.ConclusionsLaparoscopic primary closure with internal and external biliary drainage tubes is safe and an effective alternative to T‐tube placement, especially for younger patient groups able to endure bile duct exploration. Sphincter of Oddi function is well preserved to prevent recurrent bile duct stones and bile duct cancer. Procedures are safe with great feasibility.

Zn plays a key role in the synthesis and action of insulin. The aim of the present work was to determine whether a poorer Zn status was associated with insulin resistance in a group of 357 Spanish schoolchildren. Zn intake was determined by using a 3 d food record (i.e. Sunday to Tuesday). The body weight, height and waist and hip circumferences of all subjects were recorded and fasting plasma glucose, insulin and Zn concentrations were determined. Insulin resistance was determined using the homoeostasis model assessment (HOMA) marker. Children (11·5 %) with Zn deficiency (serum Zn concentration < 10·7 μmol/l) had higher HOMA values than those with a more satisfactory Zn status (1·73 (sd0·93)) compared with 1·38 (sd0·90;P < 0·05). An inverse correlation was found between the HOMA value and the serum Zn concentration (r− 0·149,P < 0·05). The risk of having a greater insulin resistance value (HOMA greater than the 75th percentile) increased with age (OR 1·438; 95 % CI 1·021, 2·027) and BMI (OR 1·448; 95 % CI 1·294, 1·619) and decreased as Zn serum levels increased (OR 0·908; 95 % CI 0·835, 0·987;P < 0·001). Moreover, an inverse relationship was observed between HOMA values and Zn dietary density (r− 0·122), and the Zn intakes of male children with a HOMA value of >3·16 made a significantly smaller contribution to the coverage of those recommended (59·7 (sd14·7) %) than observed in children with lower HOMA values (73·6 (sd18·2) %;P < 0·05). Taking into account that Zn intake was below than that recommended in 89·4 % of the children, it would appear that increasing the intake of Zn could improve the health and nutritional status of these children, and thus contribute to diminish problems of insulin resistance.

Prescription patterns for asthma medications in children and adolescents with health care insurance in the United States. Pediatr Allergy Immunol 2011; 22: 469–476.AbstractAsthma is the most common chronic condition of childhood, and its prevalence has increased over recent decades. However, many children and adolescents with asthma are not being managed in accordance with guideline recommendations. The objective of this study was to analyze prescribing patterns for asthma medications in 6‐ to 18‐yr‐olds, with a focus on those aged 6–11 yr. Data from patients enrolled for ≥6 months in PharMetrics were analyzed between June 1, 1995, and September 30, 2008. PharMetrics contains data from 45 million US patients from 85 health care plans, including standard and mail order prescription records. Prescriptions for asthma medication for each patient were recorded. The overall asthma cohort included 659,169 patients; 34,950 (5%) were classified as having severe asthma. The 6‐ to 11‐yr‐old subgroup consisted of 374,068 patients (56.7% of the overall asthma cohort). Almost 40% of the population received no medication (severe asthma 1.0%; non‐severe asthma 37.6%), with almost identical findings in the 6‐ to 11‐yr‐old subgroup. In patients with non‐severe and severe asthma, frequency of medication use was as follows: short‐acting β2‐agonists (53% and 92%), oral steroids (23% and 64%), leukotriene receptor antagonists (17% and 49%); inhaled corticosteroids alone (15% and 80%) and in combination with long‐acting β2‐agonists (10% and 22%), respectively. Results for patients in the 6‐ to 11‐yr subgroup were similar to those of the overall cohort. In conclusion, a considerable proportion of children and adolescents with asthma do not receive any asthma medication. Among those who do receive medication, adherence to current guidelines is questionable.
