PROFICIENCY LEVEL AND LANGUAGE LEARNING STRATEGIES AMONG JORDANIAN STUDENTS AT UNIVERSITI UTARA MALAYSIA
Authors: Jaradat Eshraq Mahmoud Mustafa , Bakrin Haryati 
Published: May 2017

This study examines the relationship between proficiency level and language learning strategies (LLSs) among Jordanian students enrolled at Universiti Utara Malaysia. The frequency level of the LLSs employed by the students was also investigated. The theoretical foundation for the study was provided by three comprehensive theories which are the Behaviorism, the Cognitive Psychology, and the Schema Theory. The data for the LLSs was obtained from using Oxford’s (1990) Strategy Inventory for Language Learning (SILL) that classifies six different strategies: 1) Memory Strategy (MS), (2) Cognitive Strategy (COG), (3) Compensation Strategy (COMPS), (4) Metacognitive Strategies (MET), (5) Affective Strategy (AFCS) and (6) Social Strategies (SOC). The frequency of the students’ overall use of LLSs was determined on a five-point Likert scale, ranging from high frequency use (3.5-5.0), medium frequency use (2.5-3.49), to low frequency use (1.0-2.49). Questionnaires were distributed and collected from a total of 97 students. Meanwhile, the students’ level of language proficiency was determined by their scores in the UUM English Language Proficiency Test (ELPT). Upon using the multiple regression analysis, the results show that the students used language learning strategies at a high frequency level. In addition, this study shows that there is a positive relationship between language learning strategy and proficiency level. These results indicate that proficiency level plays a vital role in determining the kinds of language learning strategy used. Curriculum designers and related bodies in Jordan should increase focus on the role of language learning strategies in promoting the acquisition of English language proficiency. The study also opens up avenues for more studies on language learning strategies not only in Jordan, but also in other countries where this area of study is lacking.
Minimize Formation Damage in Water-Sensitive Montney Formation With Energized Fracturing Fluid

Published: May 2017

Summary
Slickwater has been widely used for hydraulic fracturing because it is inexpensive and able to carry proppants into the fracture (Schein 2005; Palisch et al. 2010). This fluid, however, is unsuitable for water-sensitive formations, such as the Montney formation. This is because water saturation around the fractures increases, and the clay swells when water leaks into the matrix, both of which hinder the flow of natural gas from the matrix into the fractures. N2- or CO2-energized water-based fracturing fluids have been widely used in water-sensitive formations because they can minimize fluid leakoff during fracturing and help achieve higher-load fluid recovery during flowback (Burke and Nevison 2011; Barati and Liang 2014).
In this paper, multiphase numerical simulations are applied to study the formation-damage mitigation in the Montney tight reservoir with energized fracturing fluid. A simulation model is built and history-matched with flowback and early production data gathered from a typical Montney tight gas well. The behavior of the multiphase fluid leakoff and flowback is studied. Sensitivities of the foam quality of the fracturing fluid on the load fluid recovery are analyzed, as is the well productivity after stimulation. Statistical analysis to study the performance of energized fracturing in the water-sensitive Montney formation is conducted on the stimulation and production data of more than 5,000 Montney wells. We found that multiphase fracturing fluid has less dynamic fluid leakoff compared with that of a single-phase fracturing fluid (i.e., water). The major fluid leakoff occurs during the static leakoff period between the end of the stimulation processes and the start of the flowback. The gas phase penetrates deeper and faster into the reservoir matrix compared with the liquid phase, which contributes to the increased flowback volume of the fracturing fluid. Formation damage caused by fracturing-fluid leakoff can affect both early and long-term production. In addition, N2 foam leads to the highest-load fluid recovery in the Montney formation, which is 1.6 times that of CO2 foam. This work provides critical insights into understanding the performance of using energized fracturing fluid to mitigate formation damage in tight formations.

Published: May 2017

Summary
Although a large amount of wells has been extensively drilled to develop unconventional reservoirs, uncertainty associated with reservoir and fracture properties can significantly affect the evaluation of an individual well's performance with simulations. From the history-matching point of view, this uncertainty causes nonuniqueness of solutions that should be obtained with a robust probabilistic method without overly exhausting simulation resources. Because of the challenge in this work, a proxy-based history-matching approach can deliver unique advantages of reducing the computational requirement and providing probabilistic interpretation. The work flow presented in this paper is designed to exploit full ranges of proxy-modeling benefits from prioritizing significant reservoir properties, estimating the variation of model responses, and searching multiple history-matching solutions for reliable probabilistic forecasts. A screening process is introduced at the initial stage of the work flow with design of experiment (DOE) and response-surface methodology (RSM), so the dimensions of proxy models can be reduced. In addition, the proxy models progress through the work flow by iterations that aim to improve their accuracy. This iterative work flow efficiently uses simulation resources by use of all the completed runs to provide more information about the model responses for the subsequent iterations. While the work flow is being iterated, multiple proxy models are explored for history-matching solutions by a Markov chain Monte Carlo (MCMC) algorithm. Then, history-matching solutions are used to evaluate the probability distribution of the long-term estimated ultimate recovery (EUR). Finally, an application of the work flow to a horizontal well in the Middle Bakken is presented in this paper.

Uma das ameaças ao cerrado é a exploração de certas espécies nativas, que tem sido feita de forma extrativista e muitas vezes predatória, tornando-se imprescindíveis ações no sentido de se fazer o cultivoe domesticação destas espécies. Dentre as inúmeras frutíferas nativas que possuem alto potencial para exploração comercial, destaca-se a gabirobeira, que se encontra sob forte pressão devido ao impacto causado pela fragmentação das suas populações, seja pelo extrativismo inadequado, ou pela expansão das fronteiras agrícolas. O objetivodeste trabalho foi avaliar o uso de ácido indolbutírico na sobrevivência, brotação e enraizamento de estacas de gabirobeira. Foram coletadas estacas lenhosas de gabirobeiras da coleção do banco de germoplasma de Campomanesia spp. da UFG-Regional Jataí. Utilizaram-se estacas das espécies Campomanesia adamantium e Campomanesiapubescens segmentadas em ramos de 15 cm de comprimento contendo um par de folhas na parte apical e selecionadas as estacas que apresentavam diâmetro médio de 2,8 6 ± 1,29 cm. O experimento foi conduzido em delineamento inteiramente casualizado para cada espécie em estudo com 5 tratamentos e 4 repetições com 8 estacas/parcela. Os tratamentos foram compostos por 0, 800, 1600, 2400 e 3200 mg/L de Ácido indolbutírico (AIB). As estacas foram tratadas nas doses de Ácido indolbutírico (AIB), com 15 segundos de imersão. Após tratamento com AIB as estacas foram plantadas em bandejas de isopor com as bases perfuradas contendo como substrato areia lavada. Durante todo o período experimental foi utilizado o sistema de nebulização intermitente.Sessenta dias após a instalação do experimento as estacas foram avaliadas, quanto a Brotação, sobrevivência das estacas, porcentagem de enraizamento e porcentagem de calejamento. O uso de AIB em estacas de gabirobeiras proporcionou maior percentagem de brotação bem como maior sobrevivência das estacas, porém não proveuenraizamento.

AbstractThe objective of this paper is to assess climate change impacts on spatiotemporal changes in annual and seasonal runoff and its components in the basins of two large European rivers, the Vistula and the Odra, for future horizons. This study makes use of the Soil and Water Assessment Tool (SWAT) model, set up at high resolution, and driven by a multi-model ensemble (MME) of nine bias-corrected EURO-CORDEX simulations under two representative concentration pathways (RCPs), 4.5 and 8.5. This paper presents a wealth of illustrative material referring to the annual and seasonal runoff (R) in the reference period as well as projections for the future (MME mean change), with explicit illustration of the multi-model spread based on the agreement between models and statistical significance of change according to each model. Annual R increases are dominating, regardless of RCP and future horizon. The magnitude of the MME mean of spatially averaged increase varies between 15.8% (RCP 4.5, near future) and 41.6% (RCP 8.5, far future). The seasonal patterns show the highest increase in winter and the lowest in spring, whereas the spatial patterns show the highest increase in the inner, lowland part, and the lowest in the southern mountainous part of the basin.

Abstract
Constructing a reasonable evaluation index system is important for characterizing water and land resources and for ecological restoration. To solve random and incomplete problems using a traditional evaluation index system, a novel model for evaluating regional agricultural water resources using a resilience index system was proposed. In addition, a new method for an evaluation index system and the filtering of key indicators were investigated. Based on the structural characteristics of a regional agricultural water resource system (AWRS), the model for an evaluation index system was built by constructing a hierarchical indicator architecture using a hierarchical framework model. The index weight was calculated using criteria importance through intercriteria correlation (CRITIC). Then, index completeness was ensured using principal component analysis, and the reliability of the results was tested using the analytic hierarchy process. The model was applied to the Jiansanjiang Administration of Agricultural Reclamation in Heilongjiang, China. The main results included the following: (1) the index was optimized from 46 to 32, which identified the key indicators that affect the resilience of the Jiansanjiang Administration AWRS, and (2) an evaluation index system was constructed with a completeness of 85.6%. The results of this study provide an important and practical model for studying the resilience of related resources and environmental fields.
Molecular Systematics, Taxonomy and Distribution of the Pyrrhura Picta–Leucotis Complex
Authors: Arndt Thomas , Wink Michael 
Published: May 2017

Introduction:
The relationships within the Pyrrhura species complex are partly unresolved. In this study, a comprehensive phylogenetic analysis of the Pyrrhura picta-leucotis complex was carried out, covering all species except P. subandina.

Material and Methods:
We made a morphological analysis of 745 preserved specimens of all the taxa in different museums. Nucleotide sequences of the mitochondrial cytochrome gene were generated and used to reconstruct a molecular phylogeny of Pyrrhura.

Results and Discussion:
Our results show that the complex is divided into 6 main groups comprising 15 species. P. dilutissima, regarded up to now as a subspecies of P. peruviana, acquires species status and three new subspecies are described. We also provide evidence that P. roseifrons is a paraphyletic group, indicating the existence of probably 3 lineages of which 2 deserve species status.

OBJECTIVEThe distance to the ventral dura, perpendicular to the basion to C2 line (pB-C2), is commonly employed as a measure describing the anatomy of the craniovertebral junction. However, both the reliability among observers and the clinical utility of this measurement in the context of Chiari malformation Type I (CM-I) have been incompletely determined.METHODSData were reviewed from the first 600 patients enrolled in the Park-Reeves Syringomyelia Research Consortium with CM-I and syringomyelia. Thirty-one cases were identified in which both CT and MRI studies were available for review. Three pediatric neurosurgeons independently determined pB-C2 values using common imaging sequences: MRI (T1-weighted and T2-weighted with and without the inclusion of retro-odontoid soft tissue) and CT. Values were compared and intraclass correlations were calculated among imaging modalities and observers.RESULTSIntraclass correlation of pB-C2 demonstrated strong agreement between observers (intraclass correlation coefficient [ICC] range 0.72–0.76). Measurement using T2-weighted MRI with the inclusion of retro-odontoid soft tissue showed no significant difference with measurement using T1-weighted MRI. Measurements using CT or T2-weighted MRI without retro-odontoid soft tissue differed by 1.6 mm (4.69 and 3.09 mm, respectively, p < 0.05) and were significantly shorter than those using the other 2 sequences.Conclusions pB-C2 can be measured reliably by multiple observers in the context of pediatric CM-I with syringomeyelia. Measurement using T2-weighted MRI excluding retro-odontoid soft tissue closely approximates the value obtained using CT, which may allow for the less frequent use of CT in this patient population. Measurement using T2-weighted MRI including retro-odontoid soft tissue or using T1-weighted MRI yields a more complete assessment of the extent of ventral brainstem compression, but its association with clinical outcomes requires further study.
Sensational Internationalism
Authors: Coghlan J. Michelle 
Published: May 2017

In refocusing attention on the Paris Commune as a key event in American political and cultural memory, Sensational Internationalism radically changes our understanding of the relationship between France and the United States in the long nineteenth century. It offers fascinating, remarkably accessible readings of a range of literary works, from periodical poetry and boys’ adventure fiction to radical pulp and the writings of Henry James, as well as a rich analysis of visual, print, and performance culture, from post-bellum illustrated weeklies and panoramas to agit-prop pamphlets and Coney Island pyrotechnic shows. Throughout, it uncovers how a foreign revolution came back to life as a domestic commodity, and why for decades another nation’s memory came to feel so much our own. This book will speak to readers looking to understand the affective, cultural, and aesthetic afterlives of revolt and revolution pre-and-post Occupy Wall Street, as well as those interested in space, gender, performance, and transatlantic print culture.
Framing the Pétroleuse: Postbellum Poetry and the Visual Culture of Gender Panic
Authors: Coghlan J. Michelle 
Published: May 2017

Both during the 1871 uprising and in the wake of the Commune’s fall, Americans encountered unsettling images of female Communards marching across the pages of illustrated periodicals. In turn, a variety of American sermons and editorials railed against the revolution and claimed its “overly emancipated” females might pose the most terrifying transatlantic threat of all. My opening chapter, “Framing the Pètroleuse,” recovers the drama of that postbellum gender panic and resituates post-bellum U.S. periodical poetry written in response to it. Reading Sarah M. B. Piatt’s 1872 periodical poem, “The Palace-Burner,” alongside both Harper’s Weekly’s pictorial coverage of the Commune and the subversive sentimentality of other post-bellum poetic returns to the fiery “Women of the Commune,” I argue that Piatt’s reworking of the figure of the Parisian petroleum-thrower relies on and resists the ways the so-called “man-women” of the Commune were pictured in the U.S. press. For in bringing the pétroleuse “into the parlor,” Piatt crucially re-imagines both the fiery Communardes and the specter of domestic firebrands they were so often used to portend.
Becoming Americans in Paris: The Commune as Frontier in Turn-of-the-Century Adventure Fiction
Authors: Coghlan J. Michelle 
Published: May 2017

This chapter charts the reconfiguration of the Commune’s domestic threat in American popular fiction in the 1890s. I show how America’s fin-de-siècle preoccupation with the revolution of 1871 consistently reframes Paris as a frontier of empire even as it critically reimagines it as a site where American tourists—or, more specifically, Gilded Age American men—might be said to “find” themselves. Setting Edward King’s 1895 boys’ book, Under the Red Flag, alongside G. A. Henty’s A Woman of the Commune, and two other immensely popular but virtually forgotten historical romances of the period, The Red Republic and An American in Paris, I argue that the 1890s were a particularly apt time to revisit the Commune because of the very real labor unrest plaguing the country, and more importantly because the “romance of the Commune” served to revise American conceptions of revolution at a moment when the U.S. was reimagining its role abroad and reevaluating its attitude towards empire.
Gaia Assorted Mass Binaries Long Excluded from SLoWPoKES (GAMBLES): Identifying Ultra-wide Binary Pairs with Components of Diverse Mass

Published: May 2017

Abstract
The formation and evolution of binary star systems are some of the remaining key questions in modern astronomy. Wide binary pairs (separations >103 au) are particularly intriguing because their low binding energies make it difficult for the stars to stay gravitationally bound over extended timescales, and thus to probe the dynamics of binary formation and dissolution. Our previous SLoWPoKES catalogs, I and II, provided the largest and most complete sample of wide-binary pairs of low masses. Here we present an extension of these catalogs to a broad range of stellar masses: the Gaia Assorted Mass Binaries Long Excluded from SloWPoKES (GAMBLES), comprising 8660 statistically significant wide pairs that we make available in a living online database. Within this catalog we identify a subset of 543 long-lived (dissipation timescale >1.5 Gyr) candidate binary pairs, of assorted mass, with typical separations between 103 and 105.5 au (0.002–1.5 pc), using the published distances and proper motions from the Tycho-Gaia Astrometric Solution and Sloan Digital Sky Survey photometry. Each pair has at most a false positive probability of 0.05; the total expectation is 2.44 false binaries in our sample. Among these, we find 22 systems with 3 components, 1 system with 4 components, and 15 pairs consisting of at least 1 possible red giant. We find the largest long-lived binary separation to be nearly 3.2 pc; even so, >76% of GAMBLES long-lived binaries have large binding energies and dissipation lifetimes longer than 1.5 Gyr. Finally, we find that the distribution of binary separations is clearly bimodal, corroborating the findings from SloWPoKES and suggesting multiple pathways for the formation and dissipation of the widest binaries in the Galaxy.
