Simultaneous enhancement of the efficiency and stability of organic solar cells using PEDOT:PSS grafted with a PEGME buffer layer

We report a simple processing method to simultaneously improve the efficiency and stability of organic solar cells (OSCs). Poly(4-styrene sulfonate)-doped poly(3,4-ethylenedioxy-thiophene (PEDOT:PSS), widely used as hole transport layer (HTL) in OSCs, tends to accelerate the degradation of devices because of its hygroscopic and acidic properties. In this regard, we have modified PEDOT:PSS to reduce its hygroscopic and acidic properties through a condensation reaction between PEDOT:PSS and poly(ethylene glycol) methyl ether (PEGME) in order to improve the efficiency and stability of OSCs. As a result, the power conversion efficiency (PCE) increased by 21%, from 2.57% up to 3.11%. A better energy level alignment by the reduced work function of the modified PEDOT:PSS with a highest occupied molecular orbital (HOMO) level of poly(3-hexylthiophene-2,5-diyl) (P3HT) is considered the origin of the improved the efficiency. The half-life of OSCs with PEDOT:PSS modified with PEGME buffer layer also increased up to 3.5 times compared to that of devices with pristine PEDOT:PSS buffer layer.     

施工系统中混凝土拌和工厂位置选择综合评价模型

在大型水利水电工程施工系统中，混凝土拌和工厂位置选择涉及大量不确定性因素，本文用可能性－满意度来描述决策者对不确定性估计的主观性和管观性，论述了可能性与模糊集，满意度与信任度的对应关系，给出了可靠性－满意度的计算方法。以系统分析的层次性原理为基础，建立了厂址选择的综合评价模型，通过一个实例分析，得到几点结论。     

服装品牌形象对品牌忠诚度的影响机制

鉴于服装品牌形象对品牌忠诚度影响的复杂关系,构建服装品牌形象、感知价值、顾客满意度、品牌忠诚度的影响关系模型并提出理论假设。将服装品牌形象分为服务形象、产品形象、宣传促销形象、企业形象、店面形象和使用者形象6个结构维度。对模型和假设进行实证检验,分析结果表明:服装品牌形象从直接和间接2个方面对品牌忠诚度产生影响;感知价值通过顾客满意度所产生的中介效果间接影响品牌忠诚度;服装品牌形象与品牌忠诚度之间的关系受到顾客满意度较大影响。服装企业应通过提升品牌形象促使顾客满意度向品牌忠诚的转化。

Effects of Assigned and Participative Goal Setting on Performance and Job Satisfaction: Erratum.

Reports an error in the the article "Effects of Assigned and Participative Goal Setting on Performance and Job Satisfaction" by Gary P. Latham and Gary A. Yukl (Journal of Applied Psychology. Vol 61(2) Apr 1976, 166-171). The last paragraph in the Results section subtitled "Manipulation Check and Reliability of Measures" on page 168 was a repetition of the previous paragraph. It should be changed to read as follows: The internal consistency of the satisfaction measure was .83, The stability of the satisfaction scale, as estimated by the correlation between the before and after measures of satisfaction, was .70 (p 1977-30702-001.) Evaluated the job performance of 41 female typists under participative or assigned goal setting conditions over a 10-wk period. Significant productivity improvement occurred in both conditions during the 2nd 5 wks. There was no significant difference between conditions with respect to goal difficulty or frequency of goal attainment. Job satisfaction declined slightly in both conditions. Individual trait measures such as need for independence did not moderate the effects of either type of goal setting. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

在服装网络定制中RA对客户满意度的影响

产品推荐代理(RA)是商家为了加快消费者决策而提供的隐形推荐系统。在服装网络定制系统中,RA给客户提供具有针对性的服装信息,减少因网站信息过载而给客户造成的压力。针对国内网络定制客户,构建了RA推荐系统、客户满意度及客户忠诚度三者之间的关系概念模型。研究结果表明:推荐系统质量好坏与客户满意度之间呈现正相关关系,且定制网站形象、推荐系统信息编排合理性削弱消费者对过量信息的敏感度,以及定制服装本身质量好坏直接影响消费者对定制行为的态度。另外,消费者自身对信息判定能力较强,会在一定程度上降低对RA推荐系统的依赖性。     

西部山地旅游公共服务游客满意度评价研究——以318国道川藏线为例

文章在对相关研究进行文献综述的基础上,以318国道川藏线为例,提出西部山地旅游公共服务5个维度的游客感知假设,选用偏最小二乘结构方程模型(PLS-SEM)对游客满意度组合模型进行因子分析与假设检验。根据模型拟合结果分析,旅游信息类公共服务在西部山地旅游公共服务中供需矛盾最为突出,其次为旅游交通类公共服务和旅游安全保障管理类公共服务,相对而言,旅游基础设施类公共服务和休闲空间与旅游便民惠民类公共服务供需矛盾较小。该结果为西部山地旅游公共服务体系构建明确了发展方向。     

基于服装企业的顾客满意度测评模型
