使用Q值提升技术的增益可调GSM低噪声放大器的设计

现代CMOS工艺的发展使得在CMOS工艺上设计射频IC前端成为可能。但在传统CMOS工艺集成的片上螺旋电感品质因数(Q)偏低,大大影响其性能。通过引入负电导实现螺旋电感Q值提升,并将其应用于共栅低噪声放大器的设计。

诉讼私人成本高的影响与消减措施

当前我国存在诉讼成本、特别是诉讼私人成本太高的问题，妨碍公众选择司法途径解决纠纷以维护正当权益，应加强制度建设和道德建设，尤其是司法机关人员的行政伦理道德建设。     

学术职业资历惩罚理论的中国解释--教师流动对于NRS模型的贡献分析

通过系统梳理文献构建中国学术职业资历惩罚（NRS）的基础假设,采用针对中国11所研究型大学的学术职业调查数据库,以教师流动特征作为NRS解释的关键变量,对流动次数、流动类型两类流动特征变量与NRS的关系进行了实证检验。实证研究发现,中国客观存在NRS现象,中国大学教师资历与流动的关系、资历与收入的关系也与西方假设相一致。随着高等教育的进一步发展,中国学术职业中NRS现象会继续加大,大学应科学分析NRS现象利弊,通过促进和规范教师流动有效引导学术职业健康发展。     

Relationship of Brain-Derived Neurotrophic Factor with Interleukin-23, Testosterone and Disease Severity in Schizophrenia

Hormonal imbalance, inflammation and alteration in synaptic plasticity are reported to play a crucial role in the pathogenesis of schizophrenia. The objective of the study was to assess the serum levels of brain derived neurotrophic factor (BDNF) and its association with interleukin-23 (IL-23), testosterone and disease severity in schizophrenia. 40 cases and 40 controls were included in the study. Serum levels of BDNF, IL-23 and testosterone were estimated in all the subjects. Disease severity was assessed using Positive and Negative Syndrome Scale (PANSS). The study was designed in Tertiary care hospital, South India. The results were compared between two groups using Mann–Whitney U test. Spearman Correlation analysis was used to assess the association between biochemical parameters and PANSS. Interleukin-23 and testosterone were significantly increased and BDNF was significantly reduced in schizophrenia cases when compared with controls. BDNF was negatively correlated with IL-23 (r = − 400, p = 0.011), positive symptom subscale (r = − 0.393, p = 0.012), general psychopathology score subscale (r = − 407, p = 0.009) and total symptom subscale (r = − 404, p = 0.010). There was no significant association of IL-23 and testosterone with disease severity in schizophrenia cases. BDNF was reduced in schizophrenia cases and negatively associated with interleukin-23 and disease severity scores.     

网络围观“黑幕倾向”的负面效应及对策

作为一种基于互联网技术平台的新型政治参与方式,网络围观在技术手段上提高了网络民意在政府政策执行运作中的分量,然而网络广场对现实社会的揭示和质问总是呈现出一种“黑幕倾向”。从某种程度上讲揭露社会“黑幕”更能彰显网络围观的警示功能和监督功能,但另一方面网民热衷围观“黑幕”也容易招致负面的社会影响,分析网络围观“黑幕倾向”现象的成因并采取科学的应对措施将有助于消解中国的互联网治理困局。     

浅谈老庄消极思想中的积极因素

道家思想自从杨朱立派就在世人心中奠定了消极的思想基调。作为一种哲学思想,道家思想经历了不同阶段的发展,其中最重要也是最熟知的就是老子和庄子这两个阶段。从本质上讲,老庄思想的产生背景决定了其难免带有消极的因素,应用起来也与社会现实有偏差,但这不妨碍我们正确认识和积极应用老庄思想中的积极因素。

Forty years of the International Journal of Information Management: A bibliometric analysis

In 2019, the International Journal of Information Management (IJIM) celebrated its 40th year of publication. This study commemorates this event by presenting a retrospect of the journal. Using a range of bibliometric tools, we find that the journal has grown impressively in terms of publication and citation. The contributions come from all over the world, but the majority are from Europe and the United States. The journal has mostly published empirical articles, with its authors dominantly using quantitative methodology. Further, the culture of collaboration has increased among authors over the years. The journal publishes on a number of including managing information systems, information technologies and their application in business, technology acceptance among consumers, using information systems for decision making, social perspectives on knowledge management, and information research from the social science perspective. Regression analysis reveals that article attributes such as article order, methodology, presence of authors from Europe, number of references, number of keywords, and abstract length have a significant association with the citations. Finally, we find that conceptual and review articles have a positive association with citations.     

LaFe11.0 Co0.9 Si1.1 B0.2化合物负膨胀研究

利用电弧炉熔炼法制备了LaFe11Co0.9Si1.1B0.2化合物.扫描电镜和能量色散谱仪分析得该化合物主相为NaZn13相,还含有少量的富镧相和富铁相.X-射线衍射仪测量发现,该化合物在居里温度附近的衍射峰随着温度的升高向大角度偏移,分析软件分析并计算得到该化合物在居里温度附近具有明显的负膨胀现象.
