基于空间认知的“丝绸之路经济带”耕地利用模式

通过耕地利用模式的遥感动态监测,认知丝绸之路核心带中亚五国与我国新疆地区的农业发展现状,同时结合两地水资源禀赋特征,总结耕地扩张过快、农业结构失衡是该地区农业发展存在的主要问题,也是区域生态环境恶化的主要根源。结合中亚与新疆水资源禀赋不足且空间分布不均、但天然草场丰富的特点,提出以流域为单元,水资源约束下的控制耕地规模、调整种植结构、积极发展高端畜牧业与精品瓜果业的发展思路,从而为"丝绸之路经济带"核心区的发展提供宝贵的水资源支撑。     

城市化和农村人口犯罪现况浅析

在我国城市化加速发展的进程中,农村人口犯罪随之增多。城乡经济上的差距、文化背景以及农村基层管理均是引发农村人口犯罪的因素。预防和治理农村人口犯罪的根本在于切实解决好“三农”问题。     

国际标准关联标识符在图书馆的应用研究

国际标准关联标识符(ISLI)标准已经在新闻出版领域取得快速普及与应用。作为信息资源与用户的枢纽中心,图书馆领域与新闻出版业存在天然的联系,了解ISLI标准在新闻出版等领域的实施情况,有利于加速ISLI标准在图书馆行业的应用。文章在梳理ISLI标准的概念、编码体系、实践应用等的基础上,提出优化图书馆数字资源管理系统以支持ISLI编码的识别与管理,积极制定适合于图书馆知识资源和知识元关联的行业标准ISLI/LIB,进行基于ISLI/LIB的知识资源回溯关联、知识元关联服务以及注册中心的构建等应用对策,为用户提供更加精、准、深、专的知识资源和知识服务。     

Use of laptop computers in an academic medical library

Who borrows laptop computers in an academic health sciences library? Why do they choose to check out laptops? In a survey, laptop computer users responded that the laptops were used most frequently to do class-related work. Laptops were most often checked out because they could be taken to a quiet area of the library or to where the user had more room to work. The majority of such borrowers were satisfied or very satisfied with the laptops and the service from the library. The majority of those completing the survey were medical school students and graduate students. The circulation of laptop computers at this academic health sciences library is a very successful and popular program.     

我国科技期刊如何获取国际稿件

实质性共链分析的实证研究——对全共链分析的修正

当前的共链分析研究主要沿用了共引分析的方法,但由于网络中充斥着大量的非实质性链接,就使这种共链分析的假设前提难以成立,分析结论的可信度低.在本文中,我们提出"实质性共链分析"作为对"全共链分析"的修正,认为"实质性共链分析"比"全共链分析"更有效,并以图书馆学情报学博客共链分析为实例验证了这一假设的正确性.

Relationship between hyperuricemia and metabolic syndrome

Objective: To investigate the relationship between metabolic syndrome and hyperuricemia. Methods: A total of 2 374 subjects who received health examination in our hospital from Jan. 2004 to Dec. 2006 were enrolled in our study. Hyperuricemia is defined as ≥7 mg/dl (in men) or ≥6.0 mg/dl (in women). Metabolic syndrome was defined using AHA/NHLBI (American Heart Association/National Heart, Lung, and Blood Institute) criteria. Results: (1) The overall prevalence of hyperuricemia was 13.10%. The condition was more common in men than in women (19.07% vs 3.42%). (2) Among men, uric acid concentration is statistically significantly positively correlated with waist circumference, blood pressure, and triglyceride. Uric acid is negatively correlated with serum high-density lipoprotein-cholesterol (HDL-C). Uric acid concentration is most strongly correlated with serum triglyceride (r=0.379) and waist circumference (r=0.297). Among women, statistically significant positive correlations were noted for the serum uric acid concentrations with waist circumference, triglyceride and fasting plasma glucose. Serum triglyceride (r=0.329) and waist circumference (r=0.234) are most strongly correlated with uric acid concentrations. (3) Men with hyperuricemia had a 1.634-fold increased risk of metabolic syndrome as compared with those without hyperuricemia odds ratio (OR)=1.634, P=0.000. Women with hyperuricemia had a 1.626-fold increased risk of metabolic syndrome (OR=1.626, P=0.000) as compared with those without hyperuricemia. Conclusion: Hyperuricemia is prevalent among Chinese population. Additionally, serum uric acid is positively associated with metabolic syndrome.
