目的:分析老年患者的营养风险发生情况以及临床营养支持的应用状况。方法采用定点连续抽样方法,对住院老年患者用营养风险筛查(NRS 2002)方法进行筛查,分析营养风险发生率,对有营养风险患者进行营养支持,并观察疗效。结果老年患者中营养风险发生率较高,并随年龄增长而升高,进行营养支持者预后好。结论通过营养风险筛查对老年患者进行营养支持对临床有积极意义。 相似文献

文章利用PubMed、CNKI等国内外数据库,检索宫颈癌与乳腺癌筛查服务与利用方面的相关文献,整理归纳与比较分析发现,国外研究以社会心理学、行为学等健康信念理论为研究框架,强调社会心理、行为因素、社会资本对供需双方“两癌”筛查服务利用与提供的影响,并以此设计相应的干预策略,但是以供方视角分析筛查服务提供影响因素的研究偏少。国内的研究以需方参与筛查服务的影响因素分析为主,但是大部分研究缺少必要的理论基础,缺少对供方组织和个体层面的系统研究。国内研究者应加强对供方“两癌”筛查服务提供意愿与行为的影响因素分析,建立适合我国城乡妇女“两癌”筛查依从行为解释和干预的理论模型,积极开发提高城乡妇女参与“两癌”筛查依从行为的综合干预方案。 相似文献

Miller JC Meier E Weatherly JN 《Journal of gambling studies / co-sponsored by the National Council on Problem Gambling and Institute for the Study of Gambling and Commercial Gaming》2009,25(1):121-129
Dixon and Johnson (Analysis of Gambling Behavior 2007, 1:44–49) introduced the Gambling Functional Assessment (GFA), which attempts to identify the consequences that may be maintaining
a person’s gambling behavior. The present study had 949 introductory psychology students complete the GFA, with 124 of them
completing the measure a second time 12 weeks later. Measures of internal consistency were quite good regardless of whether
“non-gamblers” were included or excluded. Test–retest reliability was somewhat mixed, with Escape scores yielding substandard
coefficients, especially among females. Both internal and test–retest reliability were typically poorer for female respondents.
In general, the GFA performed within the limits of acceptable reliability, and coefficients compared favorably with similar
measures. Future investigations will need to determine the reliability and validity of the instrument, especially as it pertains
to its intended population, pathological gamblers. 相似文献

文学作品和影视作品是两种不同门类的艺术形式,在艺术表现方法上体现出不同特点。尽管影视艺术在人物形象的塑造方面具有形象、直观的表现优势,但它又无法取代文学作品的语言特长。中国四大古典小说的改编实践表明,经典原著中的人物形象实可以改编而不可替代。 相似文献

Televised political debates are the platforms for party leaders to outline their party's political programs and to attack those of their political opponents. At the same time journalists who moderate the debates are testing the party leaders’ ability to clearly outline and defend their programs. Television audiences of election debates evaluate these party leaders and political parties based on their television performances. Prior to the social media era, viewers’ evaluations were collected through phone surveys or web questionnaires. Nowadays viewers share their opinions in real-time on social media. Particularly Twitter is used in the Netherlands as the platform to share these opinions. In this study tweets produced by the audiences of five different televised debates that took place during the campaign for the Dutch 2012 parliamentary elections are analyzed in terms of tweeting about politicians and parties as well as political issues, as well as the content of the debates. This allowed us, using time series analysis, to test the relation between issue salience in debates and issue salience of the audience on Twitter. The issues of ‘Employment and income’ and ‘Europe’ were the most tweeted about, roughly aligning with the attention these issues received in televised debates. Findings further show there are consistent audience reactions to issues discussed in the debates: issues of ‘Housing’, ‘Care for the needy', and ‘Europe’ showing the strongest effects. However, candidates and parties are not explicitly associated by people active on Twitter when certain political issues are being debated on TV. 相似文献
