Authors: Assad Ana Paula Luppino , da Silva Thiago Ferreira , Bonfa Eloisa , Pereira Rosa Maria R. 
Published: September 2015

Objective.To evaluate maternal and neonatal outcomes in patients before and after a diagnosis of Takayasu arteritis (TA).Methods.Patients diagnosed with TA according to the American College of Rheumatology criteria were selected from the Vasculitis Outpatient Clinic of the Rheumatology Division. Healthy female staff members of this hospital of similar age and educational level were selected as the controls. The disease data were obtained from an ongoing electronic database protocol. A standardized questionnaire, emphasizing gestational history, was applied to both groups. The prevalence of fetomaternal complications and disease variables were evaluated between the groups and a statistical analysis was performed.Results.A total of 89 patients with TA (156 pregnancies) and 89 healthy controls (181 pregnancies) were evaluated. There were 75.6% pregnancies that occurred before the TA diagnosis (pre-TA group) and 24.3% after (post-TA group). In the pre-TA group, higher rates of hypertension (HTN; 27.1% vs 3.9%, p < 0.001), low birth weight (16.8% vs 6.5%, p = 0.012), and perinatal mortality (7.9% vs 0.7%, p = 0.003) were observed compared with healthy controls. The frequency of abortions and the average number of children were similar in both groups (p > 0.05). Further comparison of the pre- and post-TA groups revealed similar rates of HTN, abortion, and low birth weight, and higher rates of Cesarean delivery (p = 0.002), prematurity (p < 0.001), and infection (p = 0.045) in the latter group.Conclusion.Our study identified that patients with TA, even before the disease diagnosis, have a worse fetal outcome that is most likely associated with high rates of HTN. TA was identified as an additional differential diagnosis for HTN in pregnancy.

Published: September 2015

Objective.Anticitrullinated protein antibody (ACPA) is as sensitive as, but more specific than, rheumatoid factor (RF) and is detected earlier in rheumatoid arthritis (RA). Although part of the RA classification criteria, ACPA testing is not routinely paid for/accessible in all jurisdictions. The effect of missing ACPA testing was studied to determine whether failure to perform ACPA testing could cause a care gap in early inflammatory arthritis.Methods.Nearly 2000 patients (n = 1998) recruited to an early inflammatory arthritis cohort were allocated into 3 groups: (1) seropositive (either RF+ or ACPA+), (2) seronegative (RF− and ACPA−), and (3) missing ACPA and RF−. Analyses were adjusted for age, sex, symptom duration, and smoking status if p < 0.1. Disease Activity Score at 28 joints (DAS28) at 3 months was studied, because beyond then, disease activity is expected to determine ongoing treatment.Results.More seropositive patients fulfilled the 2010 American College of Rheumatology/European League Against Rheumatism RA criteria than seronegative patients. Group 3 was slightly older and had a smaller percentage of females, as well as shorter symptom duration and less smoking. At 3 months, group 3 was treated with fewer disease-modifying antirheumatic drugs and methotrexate (p < 0.00002) than groups 1 and 2, but there were no significant differences in DAS28, Health Assessment Questionnaire-Disability Index (HAQ-DI), proportion receiving corticosteroids, or physician’s/patient’s global assessments.Conclusion.There was no care gap in the RF-negative, unknown ACPA group because there were no significant differences in the DAS28, 3-month change in DAS28, or HAQ-DI, despite less treatment. Cost-effectiveness of ensuring ACPA testing availability in suspected RA is unknown because early outcomes did not differ, whether or not ACPA was available.
Genetic variability and interrelationships among quantitative traits in rapeseed (Brassica napus l.) advanced lines
Authors: Rameeh V. 
Published: September 2015

Improvement of the new rapeseed (Brassica napus L.) cultivars requires efficient tools to monitor traits relationship in a breeding program. Thirty six rapeseed genotypes were evaluated based on randomized complete block design with three replications at Baykola Agricultural Research Station during 2010-11 and 2011-12 growing seasons. Significant genotypes effects were exhibited for phenological traits, plant height, yield components, seed and oil yields, indicating significant genetic differences among the genotypes. Broad sense heritability values were greater for days to flowering (0.98), pods per plant (0.71) and seeds per pod (0.77), indicating that these traits are controlled mainly by genetic effects and therefore selection of these traits may be effective for improving seed yield. Pods per plant and seeds per pod were significant positive correlated with seed yield and the results of stepwise regression analysis indicated that these traits explained 73% of total yield variation. On the basis of cluster analysis, all the genotypes were classified in three groups, and the group with high mean values of plant height, pods per plant and seeds per pod had also high mean values of seed and oil yields.

Courtship sequence and evidence of volatile pheromones inPhasgonophora sulcata(Hymenoptera: Chalcididae), a North American parasitoid of the invasiveAgrilus planipennis(Coleoptera: Buprestidae)

AbstractPhasgonophora sulcataWestwood (Hymenoptera: Chalcididae) is a North American parasitoid now usingAgrilus planipennisFairmaire (Coleoptera: Buprestidae) as a novel host, and may prove useful in biocontrol. Unfortunately, information is lacking regarding mating and the presence of pheromones, which may be important when attempting to exploit this parasitoid within a management context. Herein we used olfactometer assays and behavioural observations to determine the courtship and mating sequences ofP. sulcata.A significantly higher proportion of males oriented towards females over the control arm containing filtered air in an olfactometer regardless of the age classes of females or males examined. We also observed four pre-copulatory behaviours that were consistent in all mating pairs. Our results indicate that courtship may be mediated by male perception of female-produced pheromones. Understanding the courtship sequence may be useful in rearing laboratory populations, while the putative pheromones may be useful in detection and retention ofP. sulcatapopulations.

Published: September 2015

SummaryBackground: Unnecessary hospital readmissions are one source of escalating costs that may be reduced through improved care coordination, but how best to design and evaluate coordination programs is poorly understood. Measuring patient flow between service visits could support decisions for coordinating care, particularly for conditions such as congestive heart failure (CHF) which have high morbidity, costs, and hospital readmission rates.Objective: To determine the feasibility of using network analysis to explore patterns of service delivery for patients with CHF in the context of readmissions.Methods: A retrospective cohort study used de-identified records for patients 18 years with an ICD-9 diagnosis code 428.0–428.9, and service visits between July 2011 and June 2012. Patients were stratified by admission outcome. Traditional and novel network analysis techniques were applied to characterize care patterns.Results: Patients transitioned between services in different order and frequency depending on admission status. Patient-to-service CoUsage networks were diffuse suggesting unstructured flow of patients with no obvious coordination hubs. In service-to-service Transition networks a specialty heart failure service was on the care path to the most other services for never admitted patients, evidence of how specialist care may prevent hospital admissions for some patients. For patients admitted once, transitions expanded for a clinic-based internal medicine service which clinical experts identified as a Patient Centered Medical Home implemented in the first month for which we obtained data.Conclusions: We detected valid patterns consistent with a targeted care initiative, which experts could understand and explain, suggesting the method has utility for understanding coordination. The analysis revealed strong but complex patterns that could not be demonstrated using traditional linear methods alone. Network analysis supports measurement of real world health care service delivery, shows how transitions vary between services based on outcome, and with further development has potential to inform coordination strategies.Citation: Merrill JA, Sheehan BM, Carley KM, Stetson PD.

Published: September 2015

En este estudio se determinó el cambio de uso de suelo en la región de Chignahuapan-Zacatlán, Puebla, mediante un análisis bitemporal entre 1986 y 2011; la evaluación se hizo también para cada municipio. El cambio de uso de suelo se detectó mediante el manejo de imágenes Landsat. Los usos predominantes a nivel regional son el agrícola (49.7 %) y el forestal (46.1 %). En el caso de Chignahuapan, el uso agrícola representa la actividad principal con 58.9 % del territorio, mientras que en Zacatlán predomina el uso forestal con 57.3 %. A nivel regional y para el municipio de Zacatlán, el cambio de uso del suelo forestal se correlacionó significativamente (P ≤ 0.05) con 21 variables independientes, mediante un modelo probabilístico; en el caso de Chignahuapan, el modelo consideró 16 variables. A nivel regional, la probabilidad de cambio de uso de suelo forestal varió de 5 a 90 % y a nivel municipal de 7 a 99.8 %. Finalmente, la proyección para el año 2030 estima que el riesgo de deforestación a nivel regional y en los municipios de Chignahuapan y Zacatlán será de 13,063.8, 10,966.6 y 4,405.5 ha, respectivamente.

La variación morfométrica y simetría foliar de una población de Platanus mexicana se caracterizaron en un gradiente altitudinal ripario del estado de Veracruz. Ocho caracteres morfométricos se evaluaron en 1,800 hojas provenientes de 15 individuos por sitio (70, 200, 600 y 1,700 m de altitud). Las diferencias morfométricas entre sitios (F(24, 5189) = 21.1, P < 0.05) se determinaron con un análisis de funciones discriminantes. Los caracteres relacionados con el largo y ancho de las hojas determinaron diferencias significativas (P ≤ 0.05) a nivel intrapoblacional. Con base en las distancias de Mahalanobis, el sitio ubicado a 70 m de altitud es el más distante morfométricamente. El análisis de conglomerados mostró 10 grupos foliares diferentes entre sí a lo largo del gradiente altitudinal. Existen diferencias en el tamaño foliar de mayor a menor altitud, indicando que hay hojas más grandes a 70 m. El índice de simetría foliar de P. mexicana no mostró diferencias significativas (P > 0.05) entre sitios del gradiente altitudinal del río Colipa. Los resultados fueron útiles para determinar la capacidad de respuesta de P. mexicana ante la heterogeneidad ambiental a lo largo del gradiente altitudinal del río Colipa.
Models of Integration, Models of Development in the Pacific
Authors: Borrego John 
Published: September 2015

In order to understand the processes related to integration and development in the East Asian and Latin American societies this paper attempts to place those processes in the larger context of cycles of world accumulation. Many of the societies in East Asia, Latin America, and the South, in general, were integrated into the world economy during previous cycles of hegemony and accumulation. However, in the American cycle, and particularly at the height of this cycle, East Asia was developed while most of Latin America continued to experience truncated development. How do we understand these different trajectories? We argue that the best way to understand the different processes of integration and development in these two regions during the current historical period of global capitalist accumulation is to see them all as housed in a transition period between the waning American cycle of hegemony in the world economy and a new, as yet undefined cycle. We will look at the role that the East Asian region and its societies are playing in the transition to the next cycle, as well as analyze why these societies should not be viewed as successful products of the "modernization process," as proponents of that theory argue. The "success" of these societies is rooted in their historical entry point and the geopolitical importance to the United States of the region in which they were housed, and is not necessarily repeatable by other Third World societies such as those in Latin America.
Discours scientifique et diversité linguistique en sciences humaines et sociales
Authors: Maingueneau Dominique 
Published: September 2015

Une question qui se pose aujourd’hui avec acuité est de savoir si le monolinguisme – dans la pratique il s’agit de l’anglais académique – est propice à la production des connaissances en sciences humaines et sociales. Pour assurer leur carrière, les chercheurs aspirent à faire connaître leurs travaux en publiant dans des revues internationales très normées, les plus prestigieuses. Mais on ne doit pas ignorer les limites qu’impose le fonctionnement de ces revues à la production de connaissances innovantes, susceptibles de mettre en cause les routines intellectuelles. On peut soutenir l’idée qu’en sciences humaines et sociales la préservation d’une pluralité d’espaces de production scientifiques fondés sur une pluralité de langues favorise davantage la créativité qu’un espace unique et homogène, qui tend vers un plus grand conformisme.
Paradoxes i argumentació. De la Retórica als refinaments de la matemàtica
Authors: Serrano Sebastià 
Published: September 2015

Les paradoxes -i els problemes que aquestes susciten a la lògica- poden rastrejar-se, com a objecte de reflexió, des dels sofistes fins als matemàtics i filòsofs del llenguatge contemporanis, passant per Aristòtil, Abel o Russell, mentre l’àlgebra retòrica es convertia en àlgebra sincopada i finalment en àlgebra simbòlica. La paradoxa pot ser vista com un entrebanc que impedeix el raonament asèptic, però també com un estímul provocador per a la imaginació i per a la praxi argumentativa /persuasiva, un recurs retòric que ha mobilitzat al llarg de la història les energies del pensament rigorós a fi d’evitar el «contraban» de les fal·làcies en els discursos de tota mena. Un repte, doncs, que suscita la creativitat en l’àmbit d’una cultura deutora de la tradició retòrica.

Published: September 2015

AbstractReplacing a rainfed cropping system with an irrigated one is widely assumed to be an effective measure for climate change adaptation. However, many agricultural impact studies have not necessarily accounted for the space‐time variations in the water availability under changing climate and land use. Moreover, many hydrologic and agricultural assessments of climate change impacts are not fully integrated. To overcome this shortcoming, a tool that can simultaneously simulate the dynamic interactions between crop production and water resources in a watershed is essential. Here we propose the regional production and circulation coupled model (CROVER) by embedding the PRYSBI‐2 (Process‐based Regional Yield Simulator with Bayesian Inference version 2) large‐area crop model into the global water resources model (called H08), and apply this model to the Songhua River watershed in Northeast China. The evaluation reveals that the model's performance in capturing the major characteristics of historical change in surface soil moisture, river discharge, actual crop evapotranspiration, and soybean yield relative to the reference data during the interval 1979–2010 is satisfactory accurate. The simulation experiments using the model demonstrated that subregional irrigation management, such as designating the area to which irrigation is primarily applied, has measurable influences on the regional crop production in a drought year. This finding suggests that reassessing climate change risk in agriculture using this type of modeling is crucial not to overestimate potential of irrigation‐based adaptation.

Published: September 2015

AbstractA differentially fed dual‐band implantable antenna is designed in this paper, with an additional shorting strip to achieve a size reduction. The antenna has been simulated by using one‐layer and multilayer tissue models and a human anatomical model. The prototype model is fabricated and in vitro demonstrated with skin‐mimicking phantoms, which experimentally achieves impedance bandwidths of 32 MHz at 401–406 MHz Medical Device Radiocommunications Service band and 151 MHz at 2.4–2.48 GHz Industrial, Scientific, and Medical band. Radiation characteristic has been evaluated in Computer Simulation Technology (CST) human voxel model.
Recurving western North Pacific tropical cyclones and midlatitude predictability
Authors: Aiyyer A. 
Published: September 2015

AbstractData from an ensemble prediction system are used to examine the impact of recurving tropical cyclones on downstream midlatitude forecasts. The ensemble spread, normalized by its climatology, increases after recurvature and peaks approximately 4–5 days later. It returns to climatological levels within a week after recurvature. Initially, the spread increases around the position of the tropical storm. Subsequently, it increases after extratropical transition, and it is associated with a developing wave packet in the midlatitude storm track. The enhanced spread propagates downstream approximately at the group speed of the wave packet. These results suggest that relative to the model's baseline, recurvature‐related increase in loss of forecast skill is spatially and temporally localized. Further, energy dispersion of the developing wave packet may constrain the rate at which the forecast errors propagate downstream.

AbstractWe investigated 32 net primary productivity (NPP) models by assessing skills to reproduce integrated NPP in the Arctic Ocean. The models were provided with two sources each of surface chlorophyll‐a concentration (chlorophyll), photosynthetically available radiation (PAR), sea surface temperature (SST), and mixed‐layer depth (MLD). The models were most sensitive to uncertainties in surface chlorophyll, generally performing better with in situ chlorophyll than with satellite‐derived values. They were much less sensitive to uncertainties in PAR, SST, and MLD, possibly due to relatively narrow ranges of input data and/or relatively little difference between input data sources. Regardless of type or complexity, most of the models were not able to fully reproduce the variability of in situ NPP, whereas some of them exhibited almost no bias (i.e., reproduced the mean of in situ NPP). The models performed relatively well in low‐productivity seasons as well as in sea ice‐covered/deep‐water regions. Depth‐resolved models correlated more with in situ NPP than other model types, but had a greater tendency to overestimate mean NPP whereas absorption‐based models exhibited the lowest bias associated with weaker correlation. The models performed better when a subsurface chlorophyll‐a maximum (SCM) was absent. As a group, the models overestimated mean NPP, however this was partly offset by some models underestimating NPP when a SCM was present. Our study suggests that NPP models need to be carefully tuned for the Arctic Ocean because most of the models performing relatively well were those that used Arctic‐relevant parameters.
Regime shift in Arabian dust activity, triggered by persistent Fertile Crescent drought
Authors: Notaro Michael , Yu Yan , Kalashnikova Olga V. 
Published: September 2015

AbstractThe Arabian Peninsula has experienced pronounced interannual to decadal variability in dust activity, including an abrupt regime shift around 2006 from an inactive dust period during 1998–2005 to an active period during 2007–2013. Corresponding in time to the onset of this regime shift, the climate state transitioned into a combined La Niña and negative phase of the Pacific Decadal Oscillation, which incited a hiatus in global warming in the 2000s. Superimposed upon a long‐term regional drying trend, synergistic interactions between these teleconnection modes triggered the establishment of a devastating and prolonged drought, which engulfed the Fertile Crescent, namely, Iraq and Syria, and led to crop failure and civil unrest. Dried soils and diminished vegetation cover in the Fertile Crescent, as evident through remotely sensed enhanced vegetation indices, supported greater dust generation and transport to the Arabian Peninsula in 2007–2013, as identified both in increased dust days observed at weather stations and enhanced remotely sensed aerosol optical depth. According to backward trajectory analysis of dust days on the Arabian Peninsula, increased dust lifting and atmospheric dust concentration in the Fertile Crescent during this recent, prolonged drought episode supported a greater frequency of dust events across the peninsula with associated northerly trajectories and led to the dust regime shift. These findings are particularly concerning, considering projections of warming and drying for the eastern Mediterranean region and potential collapse of the Fertile Crescent during this century.
