矿业权价款只是国家出资勘查资本权益的回报——对矿业权价款制度扩大化的思考及建议

我国的矿业权价款制度是在特定历史条件下建立的,其本质是国家出资勘查资本权益的回报。近年来,矿业权价款制度的法定内涵已被全面突破,且愈演愈烈。矿业权价款制度扩大化,不仅直接干扰了以"维护国家对矿产资源的财产权益"为基本功能的资源补偿费制度的实施,而且已成为急功近利的饮鸩止渴之举,"以矿生财"的托词,实际上也是矿业权市场秩序混乱的源头之一。矿业权价款制度扩大化其深层次原因是理论混淆和认识误区,亟待进行理性思考并予以整顿规范。

International Market Segmentation and Cross-Export Strategies Development Case Study: Iranian Furniture Industry

ABSTRACT

By developing an international market and significant differences between countries in this regard, segmentation becomes an increasingly important concept in marketing. In this article, the international market of Iranian furniture industry is segmented and cross-exporting strategies are developed to increase the market share of Iranian furniture in each segment. To achieve this, two distance functions are introduced based on correlation between export groups to cluster countries with k-means algorithm. After market segmentation for increasing sales in each segment, cross-exporting strategies are predicted by extracting association rules in each segment based on Apriori algorithm to set export baskets.     

A gossip based information fusion protocol for distributed frequent itemset mining

The computational complexity, huge memory space requirement, and time-consuming nature of frequent pattern mining process are the most important motivations for distribution and parallelization of this mining process. On the other hand, the emergence of distributed computational and operational environments, which causes the production and maintenance of data on different distributed data sources, makes the parallelization and distribution of the knowledge discovery process inevitable. In this paper, a gossip based distributed itemset mining (GDIM) algorithm is proposed to extract frequent itemsets, which are special types of frequent patterns, in a wireless sensor network environment. In this algorithm, local frequent itemsets of each sensor are extracted using a bit-wise horizontal approach (LHPM) from the nodes which are clustered using a leach-based protocol. Heads of clusters exploit a gossip based protocol in order to communicate each other to find the patterns which their global support is equal to or more than the specified support threshold. Experimental results show that the proposed algorithm outperforms the best existing gossip based algorithm in term of execution time.

Towards a Smart Tourism Business Ecosystem based on Industrial Heritage: research perspectives from the mining region of Rio Tinto,Spain

The implications of the study provide suggestions for future improvements relating to the development of industrial tourism destinations. The possibility of ‘re-using’ the old industrial and mining heritage could favour the development of an economic opportunity to the recession that affected most industrial regions after the 1960s. This paper is focused on the field of industrial heritage tourism management (IHTM) to deepen the knowledge about its business ecosystem. The IHTM is chosen because a number of evidences highlight the interconnections that exist between this field and the business ecosystem concept. To explore these interconnections, the purpose of this article is to define a frame of analysis based also on the emergent initiative of smart tourism and to set up a theoretical framework not only used to the case study of the region of Rio Tinto mine in Spain, but also used as a policy instrument to suggest propositions for recommending new paths for future studies.
