云南省团队游空间结构及其聚散效应研究

在旅游业高质量快速发展的背景下,全面厘清与掌握省域尺度范围各旅游节点在网络中的角色和地位,并解析其网络结构效应具有重大意义。针对现有研究因旅游流数据采集限制而较少对团队游空间结构研究的不足,基于云南省旅游包车客运信息,运用社会网络结合空间分析的方法,提取了云南省团队游网络空间结构特征,并对其聚散效应进行分析。结果表明:云南省团队游整体网络密度较小且淡旺季表现出相似特征,网络对各节点的旅游联系与合作影响尚未显现,暴露出云南省团队游旅游市场发展的不均衡;团队游网络外向中心势显著高于内向中心势,网络空间集聚趋势明显;通常具有较强外向中心性的旅游节点同时也具有较强内向中心性,表现出“集中—发散”的聚散规律;旅游节点的聚散效应表现为单个节点以圈层状向外递减形式发生,其扩散路径主要集中于文山—蒙自、景洪—思茅方向。整体上,云南省区域旅游业发展差异明显,应重点加强滇西南与滇西旅游区、滇中与滇东北旅游区的旅游资源开发与合作。     

The value of ongoing venture capital investment to newly listed firms

We examine whether the market values continuing venture capital (VC) investor involvement in firms post-IPO. Compared to the US, Australian VC investors exit their investments post-IPO by on-market sales rather than distribution of holdings to their investors. Lockup periods tend to be longer and ownership thresholds for reporting trades lower. We find that the market responds positively to buy transactions, negatively to sell transactions of VC investors and negatively to the resignation of VC directors. These results are consistent with VC investors in the firm having a positive influence and creating value from which the VCs and other shareholders benefit.

Understanding the factors affecting the adoption of the Internet of Things

The Internet of Things (IoTs) is widely considered as one of the most important infrastructures for promoting economic development and technological innovation. The purpose of this study is to find the key factors influencing IoT adoptions, specifically in Taiwan’s logistics industry. In this study adopts a model which is a hybrid of technology, organisation and environment (TOE) and the decision-making trial and evaluation laboratory method (DEMATEL) to evaluate the complex factors influencing the adoption of IoT. The study employs the TOE framework as a basis to develop a general evaluation framework, and the DEMATEL technique conceptualises a structural model and then identifies the causal relationships among factors through a cause-effect relationship diagram. Finally, we also divided the complex influencing factors into cause and effect groups to better clarify the causal relationships for decision-making, to ensure the efficiency of IoT adoption.     

Subordinates' perception of managers' transformational leadership style and satisfaction: a comparison of electronic manufacturing companies in Mainland China and Taiwan

Rapid economic growth has made leadership studies a significant subject in Asia. The present research compared subordinates' different perceptions of managers' transformational leadership style in Mainland China and Taiwan. Quantitative methodology was used in collecting 250 random samples from Shanghai and Taipei. Subordinates in Taiwan perceived that more managers had a transformational leadership style and also employees had higher satisfaction with managers' leadership style than those in Mainland China. The results of the present research would provide suggestions and directions for industrial managers seeking to display appropriate management behavior for an effective business environment.     

Foreign direct investment and income inequality: Does the relationship vary with absorptive capacity?

There has been little systematic empirical literature on the linkage between income inequality and FDI (Basu and Guariglia, 2007; Tsai, 1995). This paper analyzes the effects of foreign direct investment (FDI) on income inequality and asks whether the relationship depends on absorptive capacity or not, by using a cross-sectional dataset taken from 54 countries over the period 1980–2005. We adopt the endogenous threshold regression model proposed by Hansen (2000) and Caner and Hansen (2004) and find strong evidence of a two-regime split in our sample. That is, FDI is likely to be harmful to the income distribution of those host countries with low levels of absorptive capacity. By contrast, our results support the perspective that FDI has little effect on income inequality in the case of countries with better absorptive capacity. It is also shown that international trade can lead to more equal income distribution.     

交通企业员工培训外包的战略思考

目前，我国交通行业人才总量不足，高技能、高学历人才缺口大，分布不均，结构不合理，特别是物流、公路建设、公路勘测、施工、工程监理等专业技术人员明显不足。现有专业技术人员数量少与交通企业需求大之间，现有专业技术人员能力与企业快速发展的新要求之间，现有专业技术人员培训需求与交通企业培训资金紧张之间，     

一种基于Edline线特征的车道线识别算法

为了提升车道线检测的准确性和实时性,改良车道偏离预警系统的性能,提出了一种新的车道线识别算法。首先应用投影法对采集到的图像设立感兴趣区域,以此来减少图像中存在的干扰信息;其次应用一种改进后的自适应高斯滤波算法对采集所得图像进行平滑处理,减少图像中不必要的细节;最后采用边缘绘制算法进行边缘检测,在此基础上,提出一种线段检测算法——Edline算法提取边缘线,对检测到的直线段进行筛选和聚类。利用引用计数法对车道线进行跟踪和预测。结果表明,新算法的平均处理时间为17.1 ms,准确率为96.19%,将其应用在车道偏离预警系统中可以有效地提高预警效率,提升预警的准确性和响应速度。研究结果丰富了车道线识别理论,可为车道偏离预警系统的应用及基础研究提供参考。
