旅游资源核心优势的形成及整合模式--以云南旅游资源开发为例

由于国际旅游市场日益一体化 ,旅游资源及产品的市场竞争替代关系逐渐成为各个国家、地区在旅游业发展和旅游产品市场定位上需要考虑的首要因素。明确各地旅游资源在市场上最具竞争力的旅游资源 ,并通过整合 ,形成带动当地旅游业发展的“核心优势” ,是旅游规划、开发和管理者应注意的问题。     

论我国推行股票期权的法律障碍和对策

股票期权在我国是一件新生事物,也是激烈市场竞争中的一种发展趋势。股票期权法律制度是一个完整的体系,涉及到公司、证券、税收和会计等主要经济法领域。除了合同法之外,我国现行法律没有为股票期权做出太多规定。     

试论人力资源会计

人力资源会计,是会计学科中一个正在发展的新分支。根据人力资源所具备的资产特征,应将人力资源列入资产范畴。以成本法计量人力资产更符合可靠性、可验证性、可比性等公认会计原则。正确反映人力资源信息,应在财务报告中列入相关项目予以披露。     

智力资源管理的若干基本问题

智力资源管理是介于知识管理和人力资源管理之间的管理活动,目的在于优化智力活动过程,实现智力资源合理配置,提高企事业单位的创新能力。智力资源管理研究涉及认知科学、复杂性科学、跨文化的思维方式比较研究等多个领域,需要采用某些不同于逻辑分析思维的研究方法,以期突破以往知识管理研究中的障碍。智力资源管理有助于实现智力活动即脑力劳动的“精益生产”,克服某些个人或组织的智力活动效能低下、智力资源浪费的弊端,带来明显的经济效益和社会效益。     

侦查思维学研究的几个重点问题

侦查思维学研究的重点,一是侦查思维方式系统问题,即侦查思维方式由哪些具体的侦查思维活动所组成,其特点和功能是什么;二是侦查思维方式变换问题,包括变换的基本形式、动因和方法;三是侦查思维问题,主要应弄清侦查优化思维优化有哪些具体的科学方法。     

论警务战略分析

警务战略分析是警务战略指导的首要环节,具有综合性、关联性、动态性和预测性特 点。警务战略分析包括环境分析和资源分析两个方面。警务战略环境分析需要在分析政治环境、经济环 境、科技环境、社会文化环境、社会治安环境等因素的基础上,考量不同因素对警务战略的影响。分析警 务战略资源需要围绕警务战略资源的强势、弱势和警务活动面临的机遇、挑战这条主线展开。     

高校扩招应与经济社会发展相适应

高校扩招使教育投资不足、教育不公、学生就业困难等问题凸现,高校扩招要结合我国的国情,与经济社会发展相适应。要实现教育兴国,就必须保证国家财政对教育的投资。教育不公是最大的社会不公,要从制定政策入手解决。大学是培养高级建设人才的学府,必须提高质量。     

公安新闻语篇中的介入资源分析

随着大众传媒的迅猛发展,语言并不像以往语言学家宣称的那样是一种单纯的传播媒介,而更可能是一种社会实践,是社会过程的介入力量。所以,如何利用介入资源协调作者和读者的关系,对树立公安机关“立警为公,执法为民”的良好形象至关重要。     

Analysis of sensitivity and specificity: precise recognition of neutrophils during regeneration of contused skeletal muscle in rats

In this report, we applied the TissueFAXS 200 digital pathological analysis system to rapidly and accurately identify neutrophils during regeneration of contused skeletal muscle, and to provide information for follow-up studies on neutrophils to estimate wound age. Rat injury model was established, and skeletal muscle samples were obtained from the control group and contusion groups at 1, 1.5, 2, 3, 4, and 6 h, as well as at 1, 3, 5, and 15 d post-injury (n = 5 per group). The expression of nuclei and neutrophils was detected by hematoxylin and eosin (HE) staining and immunohistochemical (IHC) staining. A total of 20 injury site areas of 0.25 mm² (0.5 mm × 0.5 mm) were then randomly selected at all time points. A TissueFAXS 200 digital pathological analysis system was used to identify the positive and negative numbers. Knowledge of five professional medical workers were considered the gold standard to measure the false positive rate (FPR), false negative rate (FNR), sensitivity, specificity, and area under the curve (AUC) of receiver operating characteristic (ROC) curves. As a result, with a staining area of neutrophils from 8 µm² to 15 µm², the FPR was 4.28%–12.14%, the FNR was 12.42%–64.08%, the sensitivity was 35.92%–87.58%, the specificity was 87.86%–95.72%, the Youden index was 0.316–0.754, the accuracy was 82.80%–88.30%, and the AUC was 0.771–0.826. The AUC was largest when the cut-off value of the staining area was 12 µm². Our results show that this software-based method is more accurate than the human eye in evaluating neutrophil infiltration. Based on the sensitivity and specificity, neutrophils can be accurately identified during regeneration of contused skeletal muscle. The TissueFAXS 200 digital pathological analysis system can also be used to optimize conditions for different cell types under various injury conditions to determine the optimal cut-off value of the staining area and provide optimal conditions for further study. Furthermore, it will provide evidence for forensic pathology cases.
