关于长春市职工工作满意度的调查

工作满意度表达着人们对工作状况的自我感受,与职业变动、社会流动有一定的关联,可以成为测量社会流动的一个指标。调查发现,目前长春市职工的工作满意度并不是很高,得分仅为3．22。提高职工的工作满意度。必须做好多方面的工作,对此本提出了相应的建议。     

基因距离、隐性知识与跨国知识流动

知识的有效传播和创造需要同时掌握显性知识和隐性知识。“知识螺旋”(SECI)模型阐述了隐性知识与显性知识之间的相互转化,提示相近的基因距离能有效促进隐性知识的传播,从而促进跨国知识流动。基于45个国家在1987—2006年期间的专利互引情况的研究表明：在控制了地理距离、语言和宗教等因素后,基因距离这一生物学特征仍然显著阻碍着跨国知识流动;基因距离的阻碍作用在地理距离较小、共同语言和共同宗教的国家间更强;跨国知识流动能解释基因距离对收入差异影响的50%。因此,国家之间的深层次差异仍然阻碍着隐性知识的传播。我国需要加强国际间人才流动、支持出国留学、扩大学术交流、利用开放网络改革教育方式等措施,促进隐性知识传播,减少跨国知识流动的障碍。     

道德选择的心理分析

选择是个人在自己面临的各种可能性之间进行取舍的一种特殊活动.道德选择是内外自由耦合作用的结果,其主要的心理机制是道德判断力和自我意识.通过对道德选择的流程进行信息加工分析,可以进一步理解道德选择的具体过程.道德的两难选择则是双趋冲突、双避冲突的表现,有着不同于一般道德选择的内涵、特征及其作用,它是人们处于两种冲突的利益关系之中必须作出行为决断的选择.道德两难选择也意味着在个体面前发生了两种利益冲突,二者必选其一.个体可以通过增强平衡机制处理道德选择中的冲突和矛盾.

目的 :观察益气养阴活血通腑法为主对老年早期糖尿病肾病 (DN)的临床疗效。方法 :随机将 50例老年早期DN患者分为西药对照组 (简称对照组 ) 19例和中西药并用治疗组 (简称治疗组 ) 31例。对照组予常规降血糖、糖尿病教育及对症处理 ,治疗组加用以益气养阴活血通腑为主的中药治疗。结果 :在治疗 8周后 ,治疗组 2 4h尿清蛋白排泄量 (UAE)显著减少 (P <0 .0 1) ,与对照组比较有显著性差异 (P <0 .0 1)。结论 :益气养阴活血通腑法为主对老年早期DN具有较好的肾脏保护作用。     

做实高速公路交通安全管理工作的五点思考

高速公路具有车流量大、行车速度快等特点。一旦发生交通事故，多为车毁人亡，甚至造成多车连环追尾、死伤惨重的重特大恶性交通事故。基层高速交警除了在日常勤务中履行交通法规宣传职责，加大对交通参与者进行交通安全宣传和“五进”宣传力度外，应从贴近路面、贴近群众、贴近业主单位出发，在实际工作中寻找预防交通事故的切入点，强化交通安全管理，确保高速公路平安、畅通。     

Differentiation of vaginal cells from epidermal cells using morphological and autofluorescence properties: Implications for sexual assault casework involving digital penetration

This work explores morphological and autofluorescence differences between vaginal and epidermal cells detectable through Imaging Flow Cytometry (IFC), a non-destructive, high-throughput technique. These differences were used to build a predictive framework for classifying unknown cells as originating from vaginal or epidermal tissue, which was tested on hand swabbings with and without digital penetration. Many more cells possessing a vaginal signature (median posterior probability ≥0.90) were detected in digital penetration samples than control hand swabbings. Minimum interpretation thresholds were developed to minimize/eliminate false positives; these thresholds were also effective when screening licked hands, indicating the potential utility of this method for a variety of biological mixture types and depositional events relevant to forensic casework.     

Novel cellular signatures for determining time since deposition for trace DNA evidence

With the increase in sensitivity of DNA profiling, questions about how and when the DNA was deposited have become a driving issue in forensic cases. To address this, we propose a novel method to determine time since deposition of trace DNA samples based on morphological and autofluorescence properties of individual epithelial cells which can change as the sample ages. To develop this signature, a series of trace DNA samples were generated by contact/handling a substrate and then allowed to age anywhere between one day and more than one year prior to collection. Imaging flow cytometry (IFC) was then used to characterize the morphology and autofluorescence profiles of individual cells within each sample followed by multivariate modelling and predictive classification.Resultsshowed that epithelial cell populations could be classified with high accuracy (∼90%) into one of three time-since-deposition groups: < 1 week, between 1 week and 2 months, and > 2months. Differences across age groups were largely driven by decreases in brightfield contrast and increases in the intensity of autofluorescence. To further test this approach for forensic casework, 47 individual donor cell populations spanning each time deposition group were classified blindly against the remaining data set. Samples containing at least 75 cells and a posterior probability greater than 0.90 showed classification accuracies ∼95%. Accuracies for individual time groups were 97% (<1 week), 92% (1week-2months), 98% (>2 months) with an average posterior probability for all time groups ∼0.96. This indicates that autofluorescence and morphological analyses may provide probative information regarding time since deposition for many types of trace DNA samples in forensic casework.     

刍论细节管理的现实选择

DVC微量注射VIP对大鼠GMBF放大和电针调整效应

目的：采用中枢迷走神经背核复合体（DVC）微量注射血管活性肠肽（VIP），观察胃黏膜血流量（GMBF）变化和电针对GMBF的调整作用。方法：采用脑立体定位仪对大鼠中枢进行定位和注射，电针足三里穴，用氢气清除法测定GMBF；放射免疫法测量外周血中VIP含量。结果：DVC微量注射VIP后，血中VIP含量增加（P＜0．01），GMBF明显增加（P＜0．01）。电针（EA）足三里穴加强了GMBF放大效应。结论：DVC注射VIP对GMBF有放大效应，证实在神经－内分泌－免疫网络系统（NEIS）中VIP是重要的神经肽，DVC是VIP作用的社会中枢特异性部位之一，电针具有协同作用。
