Destination image differences between visitors and non‐visitors: a case of New York city

This note discusses the influences of previous visits on tourists' destination images. The cognitive and affective images of New York City (NYC) appear to change in certain directions after visiting. The results also found that city images have a significant influence on tourists' visit intention. However, previous visits to NYC did not play any moderating effect between destination images and visiting intention. Copyright © 2010 John Wiley & Sons, Ltd.     

信息、信任、认知冲突与董事会治理——基于问卷调查

一直以来,公司治理研究偏重董事会结构特征与公司绩效之间的关系,忽略了董事会行为过程影响。文章就董事会行为过程中一系列关键要素如信息获取、努力水平、信任关系和认知冲突对治理有效性的影响进行理论分析,构造了一个行为心理〖CD*2〗治理有效性结构方程模型。利用问卷调查数据,就上述过程变量对治理效率的影响进行实证分析。研究发现,董事会信息获取及其与管理层相互信任状况对治理效率产生显著积极影响;会议频率对战略和服务职能发挥产生显著积极作用;会议出席率、群体认知冲突等因素影响不显著。研究为改善和提高董事会治理效率提供了新的经验证据。     

一种基于无线电环境地图的路由优化机制

设计认知无线网络路由算法时,需要兼顾主用户保护与路由性能两个方面。为了提高认知无线网络中次用户之间路由的端到端性能,提出了基于无线电环境地图的路由优化机制,该机制中无线电环境地图能够为次用户提供主用户保护有关的无线电环境数据。首先,无线电环境地图根据次用户的数据请求将各授权频段的可用概率与功率控制相关信息反馈到该次用户;其次,次用户可以计算出与上一跳次用户之间的链路稳定性以及传输时延;最后,目的次用户通过计算每条路由的端到端吞吐量的期望值,然后选取期望值最大的一条路由。仿真结果表明,该路由机制在平均分组投递率、平均端到端吞吐量、平均端到端时延方面均优于对比路由算法。     

Overeducation,job mobility and earnings mobility among holders of first degrees

Overeducation has been researched extensively for nearly three decades, but some major issues in regard to it are still topics of ongoing debate. By using a panel data, that combines a survey of two cohorts of Israeli first-degree holders and data from administrative sources on jobs and wages, we examine the contribution of job turnover, cognitive abilities and continuing graduate studies to the likelihood of overeducation and wage dynamics. The study produces four main findings. First, rapid job-switching makes a negative contribution to the increase in employee’s wage and there is a negative correlation between two variables – an employee’s tenure and the number of past employers in the years after the completion of degree studies – and the probability of being overeducated. Second, the contribution of the individual’s cognitive abilities and quantitative reasoning skills to the likelihood of becoming overeducated is negative. Third, the wages of overeducated employees are some 11% lower and rise more slowly than the wages of those whose level of schooling corresponds to their jobs; this outcome may be interpreted as indicating that the ‘scars’ of being overeducated tend to be long-lasting. Fourth, the overeducated workers have lower propensity to continue to advanced academic studies.     

Veblen’s Two Types of Instinct and the Cognitive Foundations of Evolutionary-Institutional Economics

In this article, I provide a detailed examination of Thorstein Veblen’s conception of instincts, what he believed were the “prime movers in human behavior.” I outline the meaning of his division of instincts into simple and complex forms, and also document his account of their operational function and evolutionary origins. I then evaluate this understanding in relation to the new field of evolutionary psychology, and demonstrate how Veblen conceived of these instincts as interacting with habits and institutions. Finally, I illustrate one method of how the bio-cognitive level of behavioral reality could be integrated with the socio-institutional level of behavioral reality, and how an intermediate-interactive level between these two could have been generated. By doing so, I emphasize the need for scientifically accurate cognitive foundations to evolutionary-institutional economics (EIE)     

The effect of opposite sex siblings on cognitive and noncognitive skills in early childhood

We investigate the effect of having opposite sex siblings on cognitive and noncognitive skills of children in the United States at the onset of formal education. Our identification strategy rests on the assumption that, conditional on covariates, the sibling sex composition of the two firstborn children in a family is arguably exogenous. With regard to cognitive skills, learning skills and self-control measured in kindergarten, we find that boys benefit from having a sister, while there is no effect for girls. We also find evidence for the effect fading out as early as first grade.     

消费领域共同创造价值的形成机理研究

顾客既可以在生产领域,也可以在消费领域与企业共同创造价值,在消费领域中,消费者会主导价值的共同创造。消费领域的共同创造价值研究是国际学术界和实践界关注的前沿问题。本文在对相关文献梳理的基础上,以参加健康俱乐部和山地车俱乐部的消费者为调研对象,用因子分析方法归纳了消费领域共同创造价值活动的三种形式。另外,本文结合广义情绪认知评估理论分析和验证了消费领域共同创造价值的形成机理和路径。     

An economic evaluation attached to a single-centre,parallel group,unmasked, randomized controlled trial of a 3-day intensive social cognitive treatment (can do treatment) in patients with relapsing remitting multiple sclerosis and low disability

Abstract

Aims: This trial-based economic evaluation (EE) assesses from a societal perspective the cost-effectiveness of an intensive 3-day cognitive theory-based intervention (CDT), compared to care-as-usual, in patients with relapsing remitting multiple sclerosis (RRMS) and low disability (Expanded Disability Status Scale [EDDS] score < 4.0).

Materials and methods: The trial of the EE was registered in the Dutch Trial Register: Trial NL5158 (NTR5298). The incremental cost-effectiveness ratio (ICER) was expressed in cost on the Control sub-scale of the Multiple Sclerosis Self-Efficacy Scale (MSSES) and the incremental cost-utility ratio (ICUR) in the cost per Quality Adjusted Life Years (QALY) using the EQ-5D-5L. Bootstrap, sensitivity, and sub-group analyses were performed to determine the robustness of the findings.

Results: The two groups of 79 patients were similar in baseline characteristics. The base case ICER is situated in the northeast quadrant (€72 (40.74/€2,948)) due to a higher MSSES Control score and higher societal costs in the CDT group. The ICUR is situated in the northwest (inferior) quadrant due to losses in QALY and higher societal costs for the CDT group (?0.02/€2,948). Overall, bootstrap, sensitivity, and sub-group analyses confirm the base case findings. However, when the SF-6D is used as a study outcome, there is a high probability that the ICUR is situated in the northeast quadrant.

Limitations: The relative short follow-up time (6?months) and the unexpected increase in MSSES Control in the control group.

Conclusions: When using the EQ-5D-5L to calculate a QALY, CDT is not a cost-effective alternative in comparison to care as usual. However, when using self-efficacy or SF-6D as outcomes, there is a probability that CDT is cost-effective. Based on the current results, CDT for patients with RRMS clearly show its potential. However, an extended follow-up for the economic evaluation is warranted before a final decision on implementation can be made.
