Identification and Estimation of Club Convergence Models with Spatial Dependence

This article deals with heterogeneity and spatial dependence in economic growth analysis by developing a two‐stage strategy that identifies clubs by a mapping analysis and estimates a club convergence model with spatial dependence. Since estimation of this class of convergence models in the presence of regional heterogeneity poses both identification and collinearity problems, we develop an entropy‐based estimation procedure that simultaneously takes account of ill‐posed and ill‐conditioned inference problems. The two‐step strategy is applied to assess the existence of club convergence and to estimate a two‐club spatial convergence model across Italian regions over the period 1970 to 2000.     

valuation and analysis on the tourism resources in Hami Region based on GIS mapping technology

According to the data from the national standard classification and investigation of tourism resources（GB/T 18972-2003） in Hami region,the abundance,quality and dimensional distribution of the tourism resources in Hami region were evaluated based on GIS mapping technology.The evaluation results on the tourism resources in Hami region are described as follows：there are rich tourism resources categories; the quality of tourism resources is ordinary; the resources distribute equably; the number of the historical resources is much more than the natural resources,but the 1atter still has great potential for developing.All the results of the evaluation can provide important references for strategic decision making of Hami region.     

The SCOR model for the alignment of business processes and information systems

The alignment of business processes and information systems is a critical factor for both business process management (BPM) and enterprise resource planning (ERP) system efficiency. Analysing existing approaches of alignment shows the need for an independent reference model to support the mapping between organisational and informational views. The SCOR model represents a strong management tool to evaluate, control, measure and improve existing supply chain process structures, based on a business process view of supply chain highlighting the functional requirements of best practices identified. We have critically analysed the contribution of the current SCOR model to the alignment of business processes and information systems. As the alignment is currently only based on the functional realisation of best practices, we show that this alignment risks neglecting important process dependencies. An extended reference model is then proposed, including the structuring of information exchanged between processes. That results in a more complete process map highlighting all physical and informational dependencies, in a multi-view of ‘business process mapping’ including the informational dimension, and thus a more precise alignment of ERP systems with processes.

论环境人格权的独立与民法保护

环境人格利益作为人格的应有内容,是在良好的环境中生活,构成人之所以为人的要素或者条件。它体现了人对环境资源生态价值与精神价值的需求,包括环境物质性人格利益和环境精神性人格利益两个方面。在现行的民法制度无法对环境人格利益提供全面保护的情形下,应当将以环境人格利益为客体的环境人格权独立为一项具体人格权。这不仅是现代人格权的发展趋势,也是环境权私权化的必然要求。与其他具体人格权相比,环境人格权的客体具有特定性。它是一项总括性权利,具体包括生命安全和健康权、清洁空气权、清洁水权、宁静权、眺望权和景致权等。鉴于环境人格权的特殊性,对环境人格权的民法保护也具有保护限度和保护方法上的特殊性。

Exploring promising vacant technology areas in a technology-oriented company based on bibliometric analysis and visualisation*

Under technology convergence phenomenon and fast-changing social demands, it is inevitable to collect and analyze a large amount of information in order to determine a vacant technology area that can preempt the market. Thus, this research aims to propose a systematic approach to identifying vacant technology areas by reflecting the technological competitiveness of company. Vacant technology is identified as underdeveloped and undeveloped vacant areas for a firm in both macroscopic and microscopic view by generating a technology level map in a practical view. In addition, vacant technology can be identified as undiscovered vacant areas in a microscopic view by using generative topology mapping (GTM) and local outlier factor (LOF). In a respective view, the promising vacant areas are defined by developing various indicators that represent competitive strength, growth stage, and marketability in both macro and micro level, and novelty indicators that represent originality and marketability in the micro level. The proposed approach is applied to the information & communication technology (ICT) R&D technology classification to validate its usefulness. The results can be used to enhance the practical application of R&D technology planning, understand the current technology level, and perform future technology planning.
