关键词： 检验医师   规范化培训   报告签发  

摘要： 培养高素质的检验医师是保证现代实验室诊断医学持续快速发展的必要条件。我国的检验医师规范化培训已开启十余年,但目前在许多机构中,检验医师的培养与检验技师培养仍相混淆,这在很大程度上与检验报告解释签发程序还没有在我国建立有关。随着检验新技术的不断涌现,临床科室对检验报告解释签发的要求将会凸显,所以建立检验报告解释签发程序将对提升检验医师规范化培训的质量和促进临床对检验医师的需求发挥重要作用。

摘要： Malware is a pervasive problem in distributed computer and network systems. Malware variants often have distinct byte level representations while in principal belong to the same family of malware. The byte level content is different because small changes to the malware source code can result in significantly different compiled object code. To classify the packed and polymorphic malware, this paper proposes a system, for malware classification using a fast application level emulator to reverse the code packing transformation, and two flowgraph matching algorithms to perform classification. If packed, dynamic analysis employing application level emulation reveals the hidden code using entropy analysis to detect when unpacking is complete. Static analysis then identifies characteristics, building signatures for control flow graphs in each procedure. The similarities between the set of control flow graphs and those in a malware database accumulate to establish a measure of similarity. A similarity search is performed on the malware database to find similar objects to the query. Using more than 15,000 real malware, collected from honeypots, the effectiveness is validated by showing that there is an 88% probability that new malware is detected as a variant of existing malware.

摘要： Few empirical studies have been conducted to explore how customer-to-customer interactions (CCI) affect satisfaction, loyalty, and word-of-mouth (WOM) behaviors in the hospitality industry. The purpose of this paper is to address this knowledge gap. Then, the paper examines the mediating role of personal interaction quality (PIQ) and service atmospherics on CCI, satisfaction, and loyalty behaviors. The study proposes a structural model of the relationships among CCI, satisfaction, loyalty, WOM, PIQ, and service atmospherics in the context of the hospitality industry. The hypothesized relationships are then tested in an empirical study with a sample of 200 guests of Laleh Hotels in the area of *** subjects were asked to complete a self-administrated questionnaire using a convenience-sampling approach. Exploratory factor analysis, confirmatory factor analysis, one samplet-test, and structural equation modeling were employed to analyze guests’ perceptions of the research constructs. The results show that: 1) service atmospherics has a significant impact on CCI and hotel satisfaction, 2) personal interaction quality has a significant impact on hotel satisfaction and hotel loyalty, 3) hotel satisfaction has a significant impact on hotel loyalty and hotel WOM, and 4) CCI is significantly associated with hotel loyalty and hotel WOM.

关键词： Challenging behavior   Fragile X syndrome   Functional analysis   Functional behavior assessment  

摘要： This study used experimental functional analyses to examine the operant function of challenging behaviors exhibited by 12 males (ages 27-51 months) with fragile X syndrome (FXS). Eight children met criteria for negatively reinforced challenging behavior in the form of escape from demands and/or escape from social interactions. Nine children met criteria for positively reinforced challenging behavior in the form of obtaining access to highly preferred items. Attention was identified as a maintaining consequence for three children. The functional analysis was inconclusive for one child. Results suggest that, for young males with FXS, challenging behaviors may more likely be tangibly and escape maintained than attention maintained. Our findings affirm past research suggesting a unique behavioral phenotype for this population. (C) 2014 Elsevier Ltd. All rights reserved.

摘要： Background: Data on single-nucleotide polymorphisms (SNPs) have been found to be useful in predicting phenotypes ranging from an individual's class membership to his/her risk of developing a disease. In multi-class classification scenarios, clinical samples are often limited due to cost constraints, making it necessary to determine the sample size needed to build an accurate classifier based on SNPs. The performance of such classifiers can be assessed using the Area Under the Receiver Operating Characteristic (ROC) Curve (AUC) for two classes and the Volume Under the ROC hyper-Surface (VUS) for three or more classes. Sample size determination based on AUC or VUS would not only guarantee an overall correct classification rate, but also make studies more cost-effective. Results: For coded SNP data from D(>= 2) classes, we derive an optimal Bayes classifier and a linear classifier, and obtain a normal approximation to the probability of correct classification for each classifier. These approximations are then used to evaluate the associated AUCs or VUSs, whose accuracies are validated using Monte Carlo simulations. We give a sample size determination method, which ensures that the difference between the two approximate AUCs (or VUSs) is below a pre-specified threshold. The performance of our sample size determination method is then illustrated via simulations. For the HapMap data with three and four populations, a linear classifier is built using 92 independent SNPs and the required total sample sizes are determined for a continuum of threshold values. In all, four different sample size determination studies are conducted with the HapMap data, covering cases involving well-separated populations to poorly-separated ones. Conclusion: For multi-classes, we have developed a sample size determination methodology and illustrated its usefulness in obtaining a required sample size from the estimated learning curve. For classification scenarios, this methodology will help scien
