生态公益林可持续经营路径探讨——以德宏为例

公益林作为森林资源的重要组成部分,对保护和改善人类生存环境、维持生态平衡、保存物种资源、科学实验、森林旅游、国土保安、森林保护示范方面等具有重要作用。但生态公益林建设和保护面临补偿标准低、调增公益林难、公益林遭侵蚀、林分质量降低、管护能力弱等问题,探讨生态公益林可持续经营路径,实现生态经济效益双赢,对于生物多样性保护和西南生态安全屏障建设具有重要意义。

基于DEA-Malmquist的中部地区高技术产业R&D效率实证研究

在中部科技崛起思想背景下,文章基于《中国高技术产业统计年鉴(2005—2010)》数据资料,使用C2R模型、BC2模型以及DEA—Malmquist指数分析法对2004—2009年中部六省高技术产业的R&D的综合技术效率、资源配置效率、技术进步指数等因素进行实证研究。结果认为:航天航空业综合效率无效,是导致整体高技术产业TFP值低下的主要原因;电子计算机及办公设备制造业的TFP值与技术进步指数最高;技术进步对高技术产业的推动作用超过资源配置指数。文章最后还给出了几点改进非有效行业R&D效率的对策建议。     

Does Team-Based Compensation Give Rise to Problems When Agents Vary in Their Ability?

This paper reports the results of an experiment on how team heterogeneity in terms of productivity influences both the revenue sharing proposed by the principal to the team and the employees' performance. Experimental evidence shows that when the team is heterogeneous, the principal does not try to motivate the agents through her sharing offer. Regardless of the level of team-based compensation, a large amount of free riding occurs since each agent is mainly influenced by his teammate's behavior. In contrast, when the team is homogeneous, agents are better able to cooperate, reciprocating the principal's offer.     

城市化对资源消耗和污染排放的影响分析

本文选取黑龙江、上海、河南、广东和甘肃等5个省份,采用1985-2009年平衡面板数据,利用STIRPAT模型,研究了不同发展水平下的城市化对资源消耗和污染排放的影响.主要结论为:人口规模、人均收入和经济结构都是影响环境的重要因素;总体上,城市化与资源消耗和污染排放都呈正相关关系,但从5个不同发展水平的省份来看,城市化...

GB 12497-1995与GB／T12497-2006三相异步电动机经济运行判别方法比较

三相异步电动机耗电量占全国总用电量的60％以上。我国早在1990年就发布了GB12497—1990《三相异步电动机经济运行》国家强制性标准,又分别在1995年和2006年进行了两次修订。1995版标准与2006版标准在三相异步电动机经济运行判别模型和电动机在偏离额定电压工作时对综合效率补偿方法有较大的不同。文章就上述两个问题进行了比较分析,并进行了实际测量。     

Burden of illness for super-refractory status epilepticus patients

Objective: To provide an estimate of the annual number of super-refractory status epilepticus (SRSE) cases in the US and to evaluate utilization of hospital resources by these patients.

Methods: The Premier Hospital Database was utilized to estimate the number of SRSE cases based on hospital discharges during 2012. Discharges were classified as SRSE cases based on an algorithm using seizure-related International Classification of Diseases-9 (ICD-9) codes, Intensive Care Unit (ICU) length of stay (LOS), and treatment protocols (e.g. benzodiazepines, anti-epileptic drugs (AEDs), and ventilator use). Secondary analyses were conducted using more restrictive algorithms for SRSE.

Results: A total of 6,325 hospital discharges were classified as SRSE cases from a total of 5,300,000 hospital discharges. Applying a weighting based on hospital characteristics and 2012?US demographics, this projected to an estimated 41,156 cases of SRSE in the US during 2012, an estimated incidence rate of ～13/100,000 annually for SRSE in the US. Secondary analyses using stricter SRSE algorithms resulted in estimated incidence rates of ～11/100,000 and 8/100,000 annually. The mean LOS for SRSE hospitalizations was 16.5 days (median =11; interquartile range [IQR]?=?6–20), and the mean ICU LOS was 9.3 days (median =6; IQR =3–12). The mean cost of an SRSE hospitalization was $51,247 (median = $33,294; 95% CI = $49,634–$52,861).

Limitations: The analysis uses ICD-9 diagnostic codes and claims information, and there are inherent limitations in any methodology based on treatment protocol, which created challenges in distinguishing with complete accuracy between SRSE, RSE, and SE on the basis of care patterns in the database.

Conclusion: SRSE is associated with high mortality and morbidity, which place a high burden on healthcare resources. Projections based upon the findings of this study suggest an estimated 25,821–41,959 cases of SRSE may occur in the US each year, but more in-depth studies are required.
