对61例下腰痛患者的影像学检查资料进行研究,分析各影像学检查方法的效价。结果显示所有患者均进行了3种以上的影像学检查,X线检查费用占总费用的11.67%,脊髓造影占24.67%,CT占14.33%,CTM占7.33%,MRI占42%;常规X线摄片对骨性结构具有较高的分辨率,为进一步影像学检查提供依据。因此,在下腰痛的诊断过程中,必须合理地选择影像学检查方法,以最合理的花费达到正确诊断,节约卫生资源。  相似文献

This study proposes an ANP-based evaluation of retail locations. Authors acted as decision analysts and interacted with professionals in Turkish apparel retailing sector for acquiring their knowledge and expertise. As a result, evaluation criteria of the study were identified. These criteria are clustered into five groups: store, other retailers, shopping centre/business district, accessibility, and environmental. The relationship among criteria were assessed and a network was formed. ANP approach was then utilized in order to evaluate possible retail locations for the apparel stores. Besides global preferences of these alternatives, relative importance of the criteria was also revealed. Copyright © 2007 John Wiley & Sons, Ltd.  相似文献

通过对404例天津和432例Boston征婚启事的内容分析,结果发现:(1)男性更关注未来异性配偶的相貌、身材信息,而女性更关注对方的资源与承诺信息,但天津男女征婚者在这两方面都表现得更为强烈;(2)男性随年龄增长,会倾向于更大程度地寻找比自己小的女性,而中美女性则较稳定;(3)Boston人的配偶选择年龄空间较天津人广;(4)在个性特质方面,天津人更关注承诺性,Boston人更关注精神性与“享乐性”。结果表明,进化心理学对男女间差异有较大解释力,但对中美之间的文化差异却缺乏足够说服力。  相似文献

In optimal design research, designs are optimized with respect to some statistical criterion under a certain model for the data. The ideas from optimal design research have spread into various fields of research, and recently have been adopted in test theory and applied to item response theory (IRT) models. In this paper a generalized variance criterion is used for sequential sampling in the two-parameter IRT model. Some general principles are offered to enable a researcher to select the best sampling design for the efficient estimation of item parameters.  相似文献

Abstract. The paper reviews criteria which have been used to distinguish science from nonscience and from pseudo–science, and it examines the extent to which they can usefully be applied to "creation science." These criteria do not force a clear decision, especially as creation science resembles important eighteenth–century forms of orthodox science. Nevertheless, the proponents of creation science may be accused of pious fraud in failing to concede in their political battles that their "science" is tentative and tendentious and will continue to be so while it remains archaic and poorly integrated into the rest of science.  相似文献

The diagnostic accuracy of the Millon Clinical Multiaxial Inventory (MCMI) computer reports was assessed for the sample of 48 patients reliably identified as having bipolar affective disorder. Only 13 of the 48 reports were accurate in classifying the patients as having bipolar affective disorder, and this was significantly (p < .01) less than 50% of the cases. The diagnostic accuracy clearly left much to be desired. Additional research is needed to assess the validity of MCMI diagnostic suggestions for other patient groups.  相似文献

The main purpose of this paper is to improve the production planning of Pakistan Tobacco Company by selecting the most preferred brand and subsequently generating maximum profit from it. As the company produces a variety of products, the technique of multi criteria decision making is used to select the most preferred brand. To generate the maximum output from the preferred brand, different methods of qualitative managerial analysis are used, which include decision analysis to decide “why and where” the manufacturing should be carried out, transportation model to minimize the logistics cost while meeting the demand, and linear programming technique to maximize the profit generated in 2014–2015. The result obtained from analytical hierarchy process shows that the most preferred brand of the company with respect to price, quality, and comfort is John Player Gold Leaf. The decision analysis explains that this brand should be manufactured in the Jhelum factory of the company as it is more cost‐effective to produce and there is a high availability of resources. Transportation model minimizes the logistics cost of this brand from the 2 factories while meeting the demand at each provinces, central warehouse. Linear programming contributes in generating a profit of 32.738 billion PKR with an amount of 0.35 million PKR, which is more than that of the current profit of the company in the year. These results will allow the top management of the company to take corrective decisions well in time, gain a core competency in cost reduction, and make the supply chain process more efficient.  相似文献

This study presented the results of a content validity conducted on the French version of the Impact of Event Scale-Revised (IES-R). A panel of three judges proceeded to the evaluation of the items of the IES-R taking into account that it would be completed by an elderly population. The panel evaluated each item's clarity and theoretical pertinence and classified them according to the diagnostic symptoms of the post-traumatic stress disorder (PTSD) of the DSM-5. Results showed that items of the IES-R are quite clear and pertinent theoretically speaking. Regarding the classification of the items describing the criteria for the diagnostic of PTSD, the experts concluded that many items were confusing. Improvement recommendations are presented.  相似文献
