Librarians collaborate successfully with nursing faculty and a writing centre to support nursing students doing professional doctorates

This study explores how a three‐way collaboration between a University library, writing centre and faculty created avenues of training and support for students within a Doctor of Nursing Practice (DNP) program in an American University. The role of each partner involved in the collaboration is discussed alongside the profile of the DNP students. Lesson planning and classroom techniques for DNP information literacy classes are described and feedback from the partners and the students are discussed. The study confirms that collaboration is effective in improving research and writing skills. D.I.

2018年3月22日,美国总统特朗普正式签署美国政府对华贸易备忘录,这标志着“中美贸易战摩擦”的序幕正式拉开。本文以《人民日报》英文版(People’s Daily)为研究对象,用抽样选取的方式将该报纸上从2018年3月22日(星期四)到2019年3月28日(星期四)有关中美贸易摩擦的相关报道全部摘录下来,根据每篇报道的话语特点将其分成三个阶段,以内容分析和基于语料库的批判性话语分析为研究方法,分析得出中美贸易摩擦不同阶段的话语特点,进而得出相应的研究结论,同时提出一些富有实操价值的改进建议,为我国主流报纸更好地向世界传播中国思想、讲好中国故事献计献策。     

认知语言学中英汉隐喻的共性与差异

隐喻(Metaphor)是英语常用的一种修辞格,是语言中最重要的表达手段之一.运用隐喻,能形象而概括地说明问题,使语言生动、鲜明、富有表现力与感染力.通过对英汉两种语言中隐喻概念的分析比较,我们发现隐喻作为人类基本的认知活动具有其共性和差异.在此,我们将对存在的这些共性和差异进行一些探讨.     

Genetic analysis for brix weight per stool and its component traits in sugarcane （Saccharum officinarum）

Brix weight per stool (BW) of sugarcane is a complex trait, which is the final product of a combination of many components. Diallel cross experiments were conducted during a period of two years for BW and its five component traits, including stalk diameter (SD), stalk length (SL), stalk number (SN), stalk weight (SW), and brix scale (BS) of sugarcane. Phenotypic data of all the six traits were analyzed by mixed linear model and their phenotype variances were portioned into additive (A),dominance (D), additive×environment interaction (AE) and dominance×environment interaction (DE) effects, and the correlations of A, D, AE and DE effects between BW and its components were estimated. Conditional analysis was employed to investigate the contribution of the components traits to the variances of A, D, AE and DE effects of BW. It was observed that the heritabilities of BW were significantly attributed to A, D and DE by 23.9%, 30.9% and 28.5%, respectively. The variance of A effect for BW was significantly affected by SL, SN and BS by 25.3%, 93.7% and 17.4%, respectively. The variances of D and DE effects for BW were also significantly influenced by all the five components by 5.1%～85.5%. These determinants might be helpful in sugarcane breeding and provide valuable information for multiple-trait improvement of BW.     

Qualitative and quantitative analysis of goat ovaries,follicles and oocytes in view of in vitro production of embryos

Goat ovaries were collected from the slaughterhouse and categorized as right, left, corpus luteum （CL）-present and -absent group and evaluated on the basis of weight （g）, length （cm）, width （cm）, number of follicles, follicles aspirated and number and state ofcumulus-oocyte-complexes （COCs）. Comparatively higher weight [（0.66±0.02） vs （0.64±0.02） g], length [（1.17±0.02） vs （1.1 ±0.02） cm] and width [（0.77±0.02） vs （0.74±0.02） cm] were found in right ovaries than those of left. On the other hand significantly （P〈0.05） higher weight [（0.71±0.03） vs （0.64±0.01） g] and width [（0.76±0.03） vs （0.75±0.01） cm] were found in CL-present group than those of CL-absent group of ovaries. The left ovaries contained comparatively higher number of normal COCs [（1.06±0.09） per ovary] than fight ovaries [（1.03±0.10） per ovary] and the similar trend was found in total number of follicles [（4.51±0.25） vs （4.30±0.23） per ovary] and follicles aspirated [（2.55±0.14） vs （2.52±0.12） per ovary]. But the total COCs per ovary was almost similar in both ovaries [right and left： （1.85±0.12） and （1.85±0.11） per ovary, respectively]. Higher number of total COCs [（1.87±0.09） vs （1.76±0.16） per ovary], total number of follicles [（4.45±0.19） vs （4.16±0.37） per ovary], follicles aspirated [（2.55±0.10） vs （2.48±0.21） per ovary] and normal COCs [（1.12±0.07） vs （0.76±0.14） per ovary] were found in CL-absent group than those of CL-present group of ovaries.     

Effect of a distal protection device on epicardial blood flow and myocardial perfusion in primary percutaneous coronary intervention

Objective: The beneficial effect of percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI) has been well established, but there is the problem of no-reflow phenomenon which is an adverse prognostic factor in primary PCI. In the present study the effect of a distal protection device (PercuSurge GuardWire; GW) on epicardial blood flow and myocardial perfusion was evaluated. Methods and Results: Patients with AMI were randomly divided into 2 groups, the GW and the control groups. The GW group included 52 patients with AMI who underwent primary PCI with GW protection and the control group included 60 patients who underwent primary PCI without GW protection. Epicardial blood flow in the infarct-related artery (IRA) and myocardial perfusion were evaluated according to the thrombolysis in myocardial infarction (TIMI) flow grade and the myocardial blush grade (MBG). We found TIMI score of 3 was obtained significantly more frequently in the GW group (96%) than in the control group (80%). The MBG score of 3 was obtained also significantly greater in the GW group (65%) than in the control group (33%). Conclusion: Primary PCI with GW protection can significantly improve epicardial blood flow and myocardial perfusion.     

QTL analysis for some quantitative traits in bread wheat

Quantitative trait loci (QTL) analysis was conducted in bread wheat for 14 important traits utilizing data from four different mapping populations involving different approaches of QTL analysis. Analysis for grain protein content (GPC) sug- gested that the major part of genetic variation for this trait is due to environmental interactions. In contrast, pre-harvest sprouting tolerance (PHST) was controlled mainly by main effect QTL (M-QTL) with very little genetic variation due to environmental interactions; a major QTL for PHST was detected on chromosome arm 3AL. For grain weight, one QTL each was detected on chromosome arms 1AS, 2BS and 7AS. QTL for 4 growth related traits taken together detected by different methods ranged from 37 to 40; nine QTL that were detected by single-locus as well as two-locus analyses were all M-QTL. Similarly, single-locus and two-locus QTL analyses for seven yield and yield contributing traits in two populations respectively allowed detection of 25 and 50 QTL by composite interval mapping (CIM), 16 and 25 QTL by multiple-trait composite interval mapping (MCIM) and 38 and 37 QTL by two-locus analyses. These studies should prove useful in QTL cloning and wheat improvement through marker aided selection.
