Predicting Effects of Learner Characteristics on Second Language Social Media Self-Efficacy
Bailey. Daniel R. 영상영어교육학회 2017 영상영어교육 (STEM journal) Vol.18 No.4
This study identifies the relationships between self-efficacy using online Social Network Services for Language Learning (SNSLL) and the learner characteristics of group (GAO) and individual (IAO) activity orientation learning styles, utility value (UV) towards SNSLL, and SNSLL performance. Furthermore, the effect of grade allocation and actual Facebook participation on SNSLL self-efficacy was identified. A group of 148 South Korean students completed pre- and post-treatment SNSLL writing tasks and were then administered a survey to measure the aforementioned constructs. The treatment consisted of an 8-week SNSLL supplementary writing program in which students participated in Facebook groups. Results showed that students who report higher levels of UV and IAO hold higher SNSLL self-efficacy beliefs; however, GAO did not predict self-efficacy, indicating SNSLL activities may offset the disadvantage IAO learners have been found to have with classroom participation grading (Crosthwaite, Bailey, & Meeker, 2015). Grade allocation showed no effect, while actual participation revealed moderate correlation with SNSLL selfefficacy. This study fills a gap in the existing literature with respect to our understanding of how students with Group (GAO) and Individual (IAO) Activity Orientation learning styles perceive their SNSLL self-efficacy as well as to what extent learner characteristics predict SNSLL self-efficacy beliefs.

Heavy-quark meson spectrum tests of the Oktay–Kronfeld action
Bailey, Jon A.,DeTar, Carleton,Jang, Yong-Chull,Kronfeld, Andreas S.,Lee, Weonjong,Oktay, Mehmet B. Springer-Verlag 2017 European Physical Journal C Vol.77 No.11
<P>The Oktay-Kronfeld (OK) action extends the Fermilab improvement program for massive Wilson fermions to higher order in suitable power-counting schemes. It includes dimension-six and -seven operators necessary for matching to QCD through order O(A(QCD)(3)/m(Q)(3)) in HQET power counting, for applications to heavy-light systems, and O(upsilon(6)) in NRQCD power counting, for applications to quarkonia. In the Symanzik power counting of lattice gauge theory near the continuum limit, the OK action includes all O(a(2)) and some O(a(3)) terms. To assess whether the theoretical improvement is realized in practice, we study combinations of heavy-strange and quarkonia masses and mass splittings, designed to isolate heavy-quark discretization effects. We find that, with one exception, the results obtained with the tree-level-matched OK action are significantly closer to the continuum limit than those obtained with the Fermilab action. The exception is the hyperfine splitting of the bottom-strange system, for which our statistical errors are too large to draw a firm conclusion. These studies are carried out with data generated with the tadpole-improved Fermilab and OK actions on 500 gauge configurations from one of MILC's a approximate to 0.12 fm, N-f = 2 + 1-flavor, asqtad-staggered ensembles.</P>

Background: Continuous peripheral nerve blocks (CPNBs) have been investigated to control pain for abdominal surgery via midline laparotomy while avoiding the adverse events of opioid or epidural analgesia. The review compiles the evidence comparing CPNBs to multimodal and epidural analgesia. Methods: We conducted a systematic review using broad search terms in MEDLINE, Embase, Cochrane. Primary outcomes were pain scores and cumulative opioid consumption at 48 hours. Secondary outcomes were length of stay and postoperative nausea and vomiting (PONV). We rated the quality of the evidence using Cochrane and GRADE recommendations. The results were synthesized by meta-analysis using Revman. Results: Our final selection included 26 studies (1,646 patients). There was no statistically significant difference in pain control comparing CPNBs to either multimodal or epidural analgesia (low quality evidence). Less opioids were consumed when receiving epidural analgesia than CPNBs (mean difference [MD]: –16.13, 95% CI [–32.36, 0.10]), low quality evidence) and less when receiving CPNBs than multimodal analgesia (MD: –31.52, 95% CI [–42.81, –20.22], low quality evidence). The length of hospital stay was shorter when receiving epidural analgesia than CPNBs (MD: –0.78 days, 95% CI [–1.29, –0.27], low quality evidence) and shorter when receiving CPNBs than multimodal analgesia (MD: –1.41 days, 95% CI [–2.45, –0.36], low quality evidence). There was no statistically significant difference in PONV comparing CPNBs to multimodal (high quality evidence) or epidural analgesia (moderate quality evidence). Conclusions: CPNBs should be considered a viable alternative to epidural analgesia when contraindications to epidural placement exist for patients undergoing midline laparotomies.

B→Kl+l−decay form factors from three-flavor lattice QCD
Bailey, Jon A.,Bazavov, A.,Bernard, C.,Bouchard, C. M.,DeTar, C.,Du, Daping,El-Khadra, A. X.,Foley, J.,Freeland, E. D.,Gá,miz, E.,Gottlieb, Steven,Heller, U. M.,Jain, R. D.,Komijani, J.,Kronfeld American Physical Society 2016 Physical Review D Vol.93 No.2
<P>We compute the form factors for the B --> Kl(+)l(-) semileptonic decay process in lattice QCD using gauge-field ensembles with 2 + 1 flavors of sea quark, generated by the MILC Collaboration. The ensembles span lattice spacings from 0.12 to 0.045 fm and have multiple sea-quark masses to help control the chiral extrapolation. The asqtad improved staggered action is used for the light valence and sea quarks, and the clover action with the Fermilab interpretation is used for the heavy b quark. We present results for the form factors f(+)(q(2)), f(0)(q2), and f(T)(q2), where q(2) is the momentum transfer, together with a comprehensive examination of systematic errors. Lattice QCD determines the form factors for a limited range of q(2), and we use the model-independent z expansion to cover the whole kinematically allowed range. We present our final form-factor results as coefficients of the z expansion and the correlations between them, where the errors on the coefficients include statistical and all systematic uncertainties. We use this complete description of the form factors to test QCD predictions of the form factors at high and low q(2).</P>

Bailey, W.G. The Korean Society of Ginseng 1990 Journal of Ginseng Research Vol.14 No.2
Ginseng is renowned for both its medicinal and herbal uses and successful cultivation of Panax ginseng in Asia and Panax Vtiinvtiefolilim in North America has until recently taken place in the native geographical ranges of the plants. As a consequence of the potential high capital return and anticipated increases in consumer consumption, commercial cultivation of American ginseng now occurs well outside the native range of the plant in North America. In fact, the region of greatest expansion of cultivation is in the semi-arid interior region of British Columbia, Canada. Linked with this expansion is the potential domination of the ginseng industry by agricultural corporations. In the interior of British Columbia, the native decidous forest environment of eastern North America is simulated with elevated polypropylene shade and a sllrface covering of straw mulch. The architecture of these environments is designed to permit maximillm machinery useage and to minimize labour requirements. Further, with only a four-year growth cycle, plant densities in the gardens are high. In this hot, semiarid environment, producers believe they have a competitive advantage over other regions in North America because of the low precipitation rates. This helps to minimize atmospheric humidity such that the conditions for fungal disease development are reduced. If soil moisture levels become limited, supplemental water can be provided by irrigation. The nature of the radiation and energy balance regimes of the shade and much environment promotes high soil moistilre levels. Also, the modified environment reduces soil heating. This can result in an aerial environment for the plant that is stressful and a rooting zone environment that is sub-optimal. The challenge of further refining the man modified environment for enhanced plant growth and health still remains.
