卷接包集控系统网络结构的规划分析

为解决绵阳卷烟厂卷包生产过程中存在的设备自控关联性差、连锁方式难以改变、分散的设备与生产运行难以监控、生产管理模式难以满足柔性化生产等问题,引进了卷包集控系统,并对该系统的三层网络结构进行了规划设计、对比分析。通过改变三个网络层次之间的连接方式、网络拓扑结构,使卷接包生产因集控系统网络故障引起的停机时间降到最低。应用效果表明,改进后的网络结构有利于缩小网络规模,控制网络风险,保证数据交换,避免I/O整体失控,有效提高了通信网络的安全性和稳定性及网络资源的利用率。     

深度休闲对主观幸福感的影响研究——以苏南地区城市居民为例

深度休闲对优化苏南地区休闲产业建设,进一步提升居民休闲生活质量有重要影响。文章通过问卷调查的方式收集苏南地区城市居民深度休闲行为的数据,研究苏南地区城市居民深度休闲行为特征及深度休闲对主观幸福感的影响。结果发现:(1)苏南地区城市居民进行深度休闲活动的场所主要为户外;(2)闲暇时间不足是限制苏南地区城市居民进行深度休闲活动的主要因素;(3)苏南地区城市居民的深度休闲活动总体程度不高,愿意在深度休闲活动上投入大量时间和金钱的人更是少数;(4)苏南地区城市居民从事深度休闲活动产生的强烈认同感和坚持不懈的毅力对主观幸福感有着显著的积极影响。

An analysis of the greenhouse gas emissions profile of airlines flying the Australian international market

International commercial flights (with the exception of flights between countries in European Union including Iceland, Norway and Liechtenstein) are currently not subject to greenhouse gas emission reduction regulation. To formulate effective and efficiency policy to manage greenhouse gas emissions from air transport, policy makers need to determine the emissions profiles of all airlines currently flying into their country or region. In this paper, we use 2012 data on airlines' aircraft characteristics, passenger load and cargo load (obtained from statistics reported by Australian Government Bureau of Infrastructure, Transport and Regional Economics) to estimate the volume and carbon efficiency on each international route flying to and from Australia. This is the first study to use actual passenger and cargo load data to determine the greenhouse gas (specifically CO₂) efficiency of airlines operating in the Australian international aviation market. Airlines' CO₂ emission profile is dependent on many factors including but not limited to the aircraft used, payload, route taken, weather conditions. Our results reveal that the airlines’ CO₂ emission profile is not only dependent on the aircraft used and the number of passengers but also the amount of cargo on each flight.     

林权流转主导模式与制度创新

顶层制度上受相似的基本的社会条件制约,集体林权流转进而也期待形成"三权分离"的经营格局。但是,由林地、林权本身特性决定的物权式流转的主导模式,将导致林农承包权的退出。基此,通过经验与规范实证的结合分析,诸如林下经营权及其流转等有关制度性措施、实践的意义与价值及其局限性可被清晰认知,进而制度供给仍有不足也被问题化。欲有所作为并能有效应对,则林权流转在普通的方式之外,可考虑引入典权制度。而典权是一种均衡的制度安排,兼顾了社会实质正义。     

Cost-effectiveness analysis of exenatide once-weekly versus dulaglutide,liraglutide, and lixisenatide for the treatment of type 2 diabetes mellitus: an analysis from the UK NHS perspective

Objective: To assess the cost-effectiveness of exenatide 2?mg once-weekly (EQW) compared to dulaglutide 1.5?mg QW, liraglutide 1.2?mg and 1.8?mg once-daily (QD), and lixisenatide 20?μg QD for the treatment of adult patients with type 2 diabetes mellitus (T2DM) not adequately controlled on metformin.

Methods: The Cardiff Diabetes Model was applied to evaluate cost-effectiveness, with treatment effects sourced from a network meta-analysis. Quality-adjusted life years (QALYs) were calculated with health-state utilities applied to T2DM-related complications, weight changes, hypoglycemia, and nausea. Costs (GBP £) included drug treatment, T2DM-related complications, severe hypoglycemia, nausea, and treatment discontinuation due to adverse events. A 40-year time horizon was used.

Results: In all base-case comparisons, EQW was associated with a QALY gain per patient; 0.046 vs dulaglutide 1.5?mg; 0.102 vs liraglutide 1.2?mg; 0.043 vs liraglutide 1.8?mg; and 0.074 vs lixisenatide 20?μg. Cost per patient was lower for EQW than for liraglutide 1.8?mg (?£2,085); therefore, EQW dominated liraglutide 1.8?mg. The cost difference per patient between EQW and dulaglutide 1.5?mg, EQW and liraglutide 1.2?mg, and EQW and lixisenatide 20?μg was £27, £103, and £738, respectively. Cost per QALY gained with EQW vs dulaglutide 1.5?mg, EQW vs liraglutide 1.2?mg, and EQW vs lixisenatide 20?μg was £596, £1,004, and £10,002, respectively. In the probabilistic sensitivity analysis, the probability that EQW is cost-effective ranged from 76–99%.

Conclusion: Results suggest that exenatide 2?mg once-weekly is cost-effective over a lifetime horizon compared to dulaglutide 1.5?mg QW, liraglutide 1.2?mg QD, liraglutide 1.8?mg QD, and lixisenatide 20?μg QD for the treatment of T2DM in adults not adequately controlled on metformin alone.

软资源视角下城镇化动力与潜力

城市是在自然和文化力量相互作用组成的环境中产生和发展起来的,每个城市系统都存在于一个受文化和历史约束的世界中,并拥有一系列已形成的传统和价值。从城市史来看,人类智慧和文化所凝聚而形成的软资源分布、演化与城市及其市民社会的发展之间存在着耦合关系和共生规律。后工业化时代的城镇化越来越依赖于新兴产业和未来产业的发展,了解和掌握软资源的形成、积累和价值规律,利用软资源的特性来开发新兴产业,不仅有利于促进经济发展和就业增长,也有利于在新的产业上规划城镇化,提升城市的品质和内涵。     

Universal type structures with unawareness

Infinite hierarchies of awareness and beliefs arise in games with unawareness, similarly to belief hierarchies in standard games. A natural question is whether each hierarchy describes the playerʼs awareness of the hierarchies of other players and beliefs over these, or whether the reasoning can continue indefinitely. This paper constructs the universal type structure with unawareness where each type has an awareness level and a belief over types. Countable hierarchies are therefore sufficient to describe all uncertainty in games with unawareness.
