本文探索并检验了纺织服装企业管理者的新技术接受期望。基于项目反应理论中的心理测量方法,通过专家访谈与问卷调查,对55项由文献资料归纳形成的初始测量题项进行筛选,并最终保留8个题项生成新技术接受期望量表。结果显示最终量表具有较高的区分度、信度与收敛效度,且样本特征对期望测量无显著影响,可为纺织服装企业的技术接受动机研究提供测量工具与理论依据。同时,研究揭示了纺织服装企业管理者在新技术接受决策过程中的关注要素,例如技术使用者的技能素养与新技术的兼容性等。该研究可为新技术在我国纺织服装行业的推广与普及提供参考建议。

Though soil er.sion is an impor.ant concer. in Sr. Lanka, ther. is a dear.h of baseline infor.ation on soil er.sion in many ofits water.heds, which obstr.cts monitor.ng of soil er.sion and mitigating its effects. In or.er.to assess soil er.sion in a cr.tical water.hed and to identify its deter.inants, the Samanalawewa water.hed, which contains one of the main hydr.power.gener.ting r.ser.oir. in Sr. Lanka, was selected for.this study. r.mote-sensing (r.) and geogr.phic infor.ation system (GIS) based modeling as well as field exper.ments wer. employed to assess and map soil er.sion r.tes. r.sults indicated that the cur.ent r.te of soil er.sion r.nges fr.m 0 to 289 t/ha/yr. and that the aver.ge r.te of soil er.sion has been declining fr.m 20 to 4 t/ha/yr.over.a per.od fr.m 1986 to 2008. The cur.ent r.te of soil er.sion is, however. still about 14 to 33 times gr.ater.than the natur.l soil gener.tion r.te. Socioeconomic factor. and peoples’ per.eption of soil er.sion and soil conser.ation measur.s wer. examined using data collected thr.ugh a household sur.ey. Multiple r.gr.ssion analysis with eighteen covar.ates of socioeconomic char.cter.stics yielded eleven socioeconomic var.ables, viz. household size, far. labor. education, land tenur., conser.ation cost, tr.ining, committee member.hip, pr.fessional competencies, income, distance, and financial capital as the pr.dictor.var.ables of soil er.sion. Far.er. identified impr.per.soil and cr.p management pr.ctices as the major.causes of er.sion. The adoption of conser.ation measur.s, their.effectiveness, and their.impact on ecosystem ser.ices wer. also examined.

Nitr.gen (N) is the most yield-limiting cr.p nutr.ent wor.dwide. Industr.ally pr.duced N has incr.ased in cost over.the past year., and is unavailable in many r.gions ar.und the globe. Biological N fixation by r.izobial bacter.a is a gr.at under.tilized r.sour.e that this pr.ject aims to maximize. Gr.in legumes fix appr.ximately 20 to 100 kg·N·ha-1·yr.1. The amount of N supplied by fixation is affected by genes and tr.its of both the bacter.al and plant par.ner.. The objectives of this study ar. to identify Pisum sativum var.eties with high nitr.gen fixation efficiency. This is achieved by ger.plasm scr.ening and phenotypic evaluation of nodule for.ation, total plant nitr.gen, and r.sidual nitr.gen in soil. Significant differ.nces in plant total nitr.gen among the var.ous cultivated genotypes wer. found, with her.tability of 0.57. These pea var.eties left in the soil a r.sidual N that var.es between 11.21 to 65.018 ***-1. Our.findings r.veal a unique oppor.unity for.impr.ving N fixation thr.ugh genetic cr.ssing and selection.

AIM： TO evaluate the association between IeM and gastr.phar.ngeal r.flux disease （GPr.） in patients who under.ent ambulator. 24-h dual-pr.be pH monitor.ng for.the evaluation of supr.esopha.e.l symptoms. MeTHODS： A total of 632 patients who under.ent endoscopy, esopha.e.l manometr. and ambulator. 24-h dual-pH monitor.ng due to supr.esopha.e.l symptoms （e.g. globus, hoar.eness, or.cough） wer. enr.lled. Of them, we selected the patients who had nor.al esopha.e.l motility and IeM. The endoscopy and ambulator. pH monitor.ng findings wer. compar.d between the two gr.ups. r.SULTS;： A total of 264 patients with nor.al esopha.e.l motility and 195 patients with the diagnosis of IeM wer. included in this study. Ther. was no differ.nce in the fr.quency of r.flux esophagitis and hiatal her.ia between the two gr.ups. All the var.ables showing gastr.esopha.e.l r.flux and gastr.phar.ngeal r.flux wer. not differ.nt between the two gr.ups. The fr.quency of Ger. and GPr., as defined by ambulator. pH monitor.ng, was not differ.nt between the two gr.ups. CONCLUSION： Ther. was no association between IeM and GPr. as well as between IeM and Ger.. IeM alone cannot be consider.d as a definitive mar.er.for.r.flux disease.
