摘要： Background: Suicide rates are elevated among United States (U.S.) military service members. Research has found that service members with autism spectrum disorder-related (ASD-related) traits are at increased risk for suicide. Complementary lines of inquiry have suggested that unit cohesion is a protective factor against developing suicidal ideation in military service members. However, given the social difficulties inherent in ASD, it is unclear whether unit cohesion might protect against suicide risk in this population. Method: Our sample consisted of 285 active duty U.S. military service members recruited online. We examined the interaction between ASD-related traits (as measured by the Autism Spectrum Quotient [AO] ), unit cohesion, and suicide risk (as measured by the Suicidal Behaviors Questionnaire-Revised [SBQ-R]). We also conducted exploratory analyses to examine whether unit cohesion attenuates the association between ASD-related traits and suicidal intent. Results: Elevated ASD-related traits were independently associated with higher levels of global suicide risk; however, unit cohesion was not independently associated with suicide risk. Unit cohesion did not significantly interact with ASD-related traits to predict suicide risk. Finally, we found that elevated ASD-related traits and unit cohesion have an independent effect on current suicidal intent. Discussion: Our findings suggest that unit cohesion might not buffer the effect of ASD-related traits on suicide risk. However, our results do show that greater unit cohesion may be independently associated with decreased suicidal intent. This study is limited by a cross-sectional design and use of self-report measures.

摘要： 目的:研究血脂检验在糖尿病患者中的应用效果及对继发性并发症发生的作用。方法:2018年4月-2019年5月收治糖尿病患者40例作为试验组,同时选取同期体检的健康志愿者40例作为对照组。比较两组高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)、甘油三酯(TG)、总胆固醇(TC)及载脂蛋白(ApoA1、ApoB)水平。结果:试验组HDL-C、ApoA1水平显著低于对照组,LDL-C、TG、TC、ApoB水平显著高于对照组,差异均有统计学意义(P<0.05)。结论:对糖尿病患者给予血脂检验能够对其继发性并发症的发生进行有效判断,有利于制定相应的治疗预防措施,具有良好的检验价值。

关键词： 企业家精神   创新精神   冒险精神   企业成长  

摘要： 本文对企业家精神、企业成长及二者相互关系的研究文献进行了回顾,归纳提出了3个基本假设和16个从属假设。借助剔除了缺失项后的2321个中国上市公司面板数据,利用结构方程模型分析工具,透过研究所构建的模型,对本文提出的各个研究假设进行了检验。本文基于样本公司数据,测算了企业家精神水平,并对不同类型企业家精神水平进行了简单分析。研究检验了样本公司数据与所构建模型的拟合性,发现样本公司数据能够与模型较好拟合。隐变量模型检验发现,关于冒险精神与创新精神之间存在互为因果关系的假设,以及冒险精神对企业成长具有显著负向影响的假设,得到了检验的严格的支持;但创新精神与企业成长之间存在显著正向影响的假设没能得到严格支持。在观察变量之间关系方面,只有4个从属假设得到了检验的严格支持。此外,研究发现,子样本与总体样本之间的检验结果存在显著差异,子样本之间在模型匹配性与输出结果上都存在显著差异;只有民营企业与制造业子样本能够与模型很好拟合,并输出有效检验结果。

关键词： 临床检验中心   分级诊疗   区域检查   作用  

摘要： 目的探究区域临床检验中心在分级诊疗中的作用。方法选取2019年1-8月于6家医疗机构进行疾病检查的患者420例为研究对象。比较区域临床检验中心成立半年前、成立后半年及成立后一年的就诊患者的满意度、检查水平及医疗资源的差异。结果区域临床检验中心成立后,患者及医院职工的满意度均不断提升,且成立半年前与成立半年后、成立一年后患者及职工的满意度比较,差异均有统计学意义(P<0.05)。且6家医疗机构8个血常规检测项目的临床检验合格率明显低于区域临床检验中心的合格率,差异有统计学意义(P<0.05)。区域临床检验中心成立后,医疗机构总职工人数、来访检验人数、总住院人数及床位利用率均不断升高,转院率明显降低。结论区域临床检验中心在分级诊疗中的推广实施可有效促进医疗资源的优化使用,提高医疗服务的质量,提升职工与患者满意度,对促进医疗事业长远发展具有积极意义。

关键词： 高效过滤器   完整性测试   质量源于设计   质量风险管理  

摘要： 药包材和辅料是药品不可分割的重要辅助成分,与药品质量安全息息相关。部分直接接触药品的药包材是在C级或更高级别的洁净室内生产的,此时高效过滤器的完整性(泄漏率)对洁净环境的影响至关重要,因此安装完成和运行期间的完整性测试就成为极端必要的确认项目。现针对高效过滤器完整性测试,分析该项目在药包材和辅料洁净环境检验检测中的重要性和缺失原因,并由点及面,指出当前药包材和辅料生产企业在质量风险管理上的不足之处,有助于药包材和辅料生产企业加强质量风险管理的意识,协同制药企业提升药品质量,将药品质量风险降到最低。

摘要： Although stand delineation approach based on aerial photographs and field survey produces high accuracy maps, it is labour-intensive and time consuming. Furthermore, conventional forest stand maps may have some uncertainties that can hardly be verified due to the experiments and skills of photo-interpreters. Therefore, researchers have been seeking more objective and cost-effective methods for forest mapping. LiDAR (Light Detection and Ranging) data have a high potential to automatically delineate forest stands. Unlike optical sensors, LiDAR height data provides information about both the horizontal and vertical structural characteristics of forest stands. However, it deprives of spectral data that may be successfully used in separating tree species. In this study, we investigate the potential of LiDAR - WorldView-3 data synergy for the automatic generation of a detailed forest stand map which can be used for a tactical forest management plan. Firstly, image segmentation was applied to LiDAR data alone and LiDAR/WorldView-3 data set in order to obtain the most suitable image objects representing forest stands. Visual inspection of the segmentation results showed that image objects based on the LiDAR/WorldView-3 data set were more compatible with the reference forest stand boundaries. After the segmentation process, the LiDAR and LiDAR/WorldView-3 data sets were independently classified using object-based classification method. We tested two levels of classification. The first was a detailed classification with 14 classes considering reference stand types. The second was the rough classification with 9 classes where some stand types were combined. The mean, standard deviation and texture features of LiDAR metrics and spectral information were used in the classification. The accuracy assessment results of LiDAR data showed that the Overall Accuracy (OA) was calculated as 0.31 and 0.43, and the Kappa Index (KIA) was calculated as 0.26 and 0.32 for the detailed and roug

关键词： 薪酬激励   人力资源管理效率   DEA模型   回归分析  

摘要： 合理的薪酬体系与企业生存发展息息相关,而我国薪酬体系主要存在的问题是制度不健全,薪酬结构过于单一,绩效考核评价体系存在漏洞,薪酬水平不能适应现代企业发展的需求.薪酬激励对企业人力资源管理效率的影响主要通过三大机制,分别是调动员工的积极性,帮助企业留住高素质人才,提升企业员工的凝聚力.本文实证分析表明:员工基本工资水平提升1个单位,能够促进企业人力资本管理效率上升0.166个单位,员工奖金水平提升1个单位能够带动企业人力资源管理效率上升0.415个单位.与国有企业相比私营企业更有利于促进其人力资源管理效率水平提升.同时企业经营时间越长,越有利于促进其人力资源管理效率水平提升.

关键词： 税收优惠   产能利用率   产能过剩   投资趋同   过度投资   机制  

摘要： 论文通过实证检验税收优惠对企业产能利用率的影响机制,讨论产能过剩的形成过程。结果发现,在税收激励下,过度投资是降低产能利用率的部分中介,行业投资趋同是影响企业产能利用率的外在调节机制;但这种调节和中介机制在国有企业和非国有企业作用不同;税收优惠对企业产能利用率的影响从促进到降低要经历一个动态的情境变化过程,只有行业投资趋同程度较高且企业存在严重过度投资时,税收优惠才会导致产能过剩。因此,通过监控行业趋同程度和企业投资效率,精准地实施税收优惠政策,不仅可以通过税收激励提高企业产能利用率,而且可以避免产能过剩。
