Economic impact of introducing TYRX amongst patients with heart failure and reduced ejection fraction undergoing implanted cardiac device procedures: a retrospective model based cost analysis

Background and aims: Infection is a serious and expensive complication of Cardiac Implantable Electronic Device (CIED) procedures. A retrospective based cost analysis was performed to estimate Trust level savings of using the TYRX antibacterial envelope as a primary prevention measure against infection in a tertiary referral centre in South London, UK.

Methods: A retrospective cohort of heart failure patients with reduced ejection fraction undergoing Implantable Cardioverter Defibrillator (ICD) or Cardiac Resynchronization Therapy (CRT) procedures were evaluated. Decision-analytic modelling was performed to determine economic savings of using the envelope during CIED procedure vs CIED procedure alone.

Results: Over a 12?month follow-up period following CIED procedure, the observed infection rate was 3.14% (n?=?5/159). The average cost of a CIED infection inpatient admission was £41,820 and, further to economic analysis, the additional costs attributable to infection was calculated at £62,213.94. A cost saving of £624 per patient by using TYRX during CIED procedure as a primary preventative measure against infection was estimated.

Conclusions: TYRX would be a cost-saving treatment option amongst heart failure patients undergoing ICD and CRT device procedures based on analysis in the local geographical area of South London. If upscaled to the UK population, we estimate potential cost savings for the National Health Service (NHS).     

PERIODIC,COMPLETE‐PARTICIPATION TRADE IN THE LAGOS‐ROCHETEAU MODEL

This paper contributes to a recent policy discussion regarding the costs and benefits of setting up a centralized electronic trading platform to replace over‐the‐counter (OTC) markets. We modify the Lagos and Rocheteau (2009, henceforth LR) asset trading model by replacing their investor‐dealer random matching and bilateral trade with a centralized competitive market that opens periodically. This arrangement preserves the main tension and trade‐off in LR. We then analyse and quantify when to introduce a centralized market and how frequently it should open in order to make it as efficiently as the decentralized OTC market in LR.     

农产品电子订单质押融资模式分析

农产品电子订单质押是线上农产品供应链金融具体运作模式之一,对克服农产品供应链中中小企业融资困难具有重要意义。恰当的模式设计有助于业务的有序健康发展,藉此,针对这一问题进行研究,并从参与业务的网络平台这一视角把运作模式分为基于第三方B2B平台、基于银行自营B2B平台及基于P2P平台三种,并依据融资主体所在供应链中的位置不同,又把每种模式分为上游订单质押融资模式及下游订单质押融资模式两种情形,为呈现三种模式间的差异,选择参与主体、融资主体、授信主体、审查主体、担保类型、风险强度、核心企业重要性七个维度对其进行了比较分析。

基于Q-Learning的多功能雷达认知干扰决策方法

针对多功能雷达和认知电子战的快速发展所导致传统干扰决策方法难以适应现代化战争的问题，提出了一种基于Q-Learning的多功能雷达认知干扰决策方法。通过对比认知思想和干扰决策原理，将Q-Learning运用于认知干扰决策中并提出了认知干扰决策的算法步骤。以某多功能雷达为基础，通过分析其工作状态及对应干扰样式构建雷达状态转移图，通过仿真试验分析了各参数对决策性能的影响，为应对实际战场提供参考。仿真了在新状态加入下的决策过程、实际战场中转移概率对决策路径的影响以及四种主要干扰决策方法的决策性能对比。试验表明，该方法能够通过自主学习干扰效果完成干扰决策，更加贴合实际战场，对认知电子战的发展有一定的借鉴意义。     

电子货币视角下的商业银行流动性需求

电子货币的快速发展已经给传统金融理论带来了挑战,特别是对以货币作为经营对象的商业银行经营管理产生了明显的冲击。文章以电子货币发展为视角,尝试性地引入凯恩斯的货币需求理论分析商业银行的流动性需求,旨在为商业银行的流动性管理提供有益的思路。     

应用二次过滤模型的干扰任务分配

针对自卫电子对抗中干扰任务分配对资源使用效率的问题，以“一对一”干扰为例，首先构建了干扰任务分配流程，并建立任务程度模型与干扰任务过滤模型，通过二次过滤筛选得到对我方威胁度大且能够被有效干扰的目标；然后根据节约干扰资源的原则，建立以总干扰功率最小为目标函数的干扰任务分配模型；最后采用二进制GPSO（Genetic-Particle Swarm Optimization）算法进行求解，提高了得到最优解的收敛速度、精度以及全局搜索能力。仿真表明，提出的干扰任务分配模型可以较好地筛除威胁程度低及干扰程度小的目标，节约了不必要的资源从而提高了资源的利用率。     

A study of factors influencing consumers＇ behavior in recycling waste household electronic appliances

The innovation of technologzv and the improvement of people＇s living standard accelerate the replacement of consumer electronic appliances, resulting in a significant increase of waste household electronic appliances （WHEA）. To address the environmental problems of WHEA, many countries have enacted legislation according to WHEA management, including collecting, processing and recycling. The regulations on the management of WHEA were also drafted in China and pilot programs of WHEA recycling management encountered difficulties in collecting WHEA. The success of a recycling scheme is dependent on people＇s willingness of participating in the scheme, This paper applies Ajzen＇s theory of planned behavior to seek the main factors to engourage consumers to participate in WHEA recycling management in China. Data from a survey conducted with a sample of 633 consumers show that service motivation is the first predictor of participation behavior intention, followed by environmental behavior attitude, economic motivation, subjective norm. and perceived behavior barrier. Environmental knowledge is found not to be the predictor of behavior intention in this recycling scheme. Study results also suggest that publicity is the key situational factor in the WHEA recycling management. Recycling network and policy have little influence on changing consumers＇ current behavior intention and participation. Implications of the findings are discussed and future research directions are suggested in the end.
