建立了装备保障分队专业划分模式的评价指标体系,引入级别不劣于关系,用ELECTREШ方法对装备保障分队专业划分的各种模式进行评价,为装备保障分队模式选择时进行定量分析提供了新的思路。通过分析计算,得出了装备保障分队按混合模式分类时产生的装备保障效能最高,其次是按技术构成分类模式,再次是按目前装备分类模式的结论,这一结论反映了未来信息化装备保障发展的趋势。     

论商业秘密的知识产权保护

随着我国市场经济的快速发展及后WTO时代国际经济商事交往的密切,我国既有法律体系的缺陷与商业秘密法律保护之间的矛盾日益凸显。本文从比较法的视觉指出,当前我国商业秘密的法律保护应充分适应并借鉴TRIPs协议等相关国际条约的规定,明确商业秘密的知识产权性质,以切实有效地保护我国各类民事主体的商业秘密权利,促进社会经济发展。     

Exploring technology readiness for mobile payment app users

ABSTRACT

The study aims to better understand the various technology readiness segments by assessing how their readiness relates to demographics variables and their adoption, attitude, ease-of-use, usefulness and continuance intention to use mobile payment apps using the technology readiness index. Using a convenience sample of 416 from a consumer panel, a two-step cluster analysis shared similarities with three of the original technology readiness segments (pioneers, paranoids and explorers) while the other two segments clustered together into a fourth segment, hesitant-sceptics. The results indicate that South African mobile users are ready to use mobile payment applications, with the ‘explorer’ emerging as the best segment to target due to optimism levels, while the hesitant-sceptic segment represent the key to unlocking the real potential value of mobile payment apps. Understanding different segments provides marketers with the opportunity to select viable segments and to customise strategies to increase uptake and continued use according to customer needs.

Measuring of International Financial Integration with a Multicriteria Decision Aid Approach

ABSTRACT

Despite the diversity of advanced approaches, the concept of ‘financial integration’ couldn’t be explicitly analyzed. Indeed, empirical studies have shown that the measures of international financial integration are one-dimensional analysis. Due to the ambiguity of the concept and its multiple determinants, it must be analyzed in multidimensional levels. The interest of this research is a proposal of a decision aid by a multicriteria approach (ELECTRE TRI) for determining the ranking of 47 countries according to the links between their degree of international and financial dependencies and the behavior of financial actors (trying to make governance decisions or diversification strategies of international portfolio).

Accounting for farmers’ production responses to environmental restrictions within landscape planning

Environmental planning aims to safeguard and foster the ecological functionality of agricultural landscapes. In order to reach a sustainable development of agricultural landscapes, in addition to ecological objectives socio-economic ones also need to be considered. In this context, the authors draw attention to three points. First, whenever ecologically sensitive areas (“ecological sites”) are used for agricultural production, it is necessary to take account of the fact that farmers tend to adapt to environmental requirements by production responses outside the ecological site itself. Second, in order to identify the socially most “desirable” land-use responses it is necessary to supplement the above-mentioned environmental objectives by socio-economic ones. Third, when choosing an appropriate model for such multi-criteria decision analysis, the question of substitutability between criteria is of utmost importance. The paper discusses the above-mentioned issues against the background of a case study of environmental planning for an ecologically very valuable agricultural landscape in Germany, the Bayerisches Donauried. Two models of multi-criteria decision analysis (MCDA) are applied, one based on the “single synthesizing criterion” method, and the other one based on the “synthesis by outranking” method. The models serve to evaluate four different land-use options, using criteria mainly derived from landscape functions and weights gained from interviews with major stakeholders. The paper presents the models’ results concerning the ranking of the different land-use options and discusses the implications for agri-environmental policies and rural development planning.     

ELECTRE TRI for Groups with Imprecise Information on Parameter Values

ELECTRE TRI is a well-known method to assign actions to predefined ordered categories, considering multiple criteria. Using this method requires setting many parameters, which is often a difficult task. We consider the case where a group of Decision Makers (DMs) is unsure of which values each parameter should take, which may result from insufficient, imprecise or contradictory information, as well as from lack of consensus among the group members. In a framework where DMs provide constraints bounding and interrelating the parameter values, rather than fixing precise figures, we discuss the problem of finding the best and worst category that each action may attain.     

Corporate environmentalism: tracing the links between policies and performance using corporate reports and public registers

Within this paper, we consider whether it is possible to trace the links between the procedural and the substantive dimensions of corporate environmentalism using information that is in the public domain – most notably in corporate reports and in pollutant releases and transfer registers (PRTRs) such as the US Toxics Release Inventory (TRI) and the EU Polluting Emissions Register (EPER). Based on an analysis of firms in the oil and gas sector, and specifically of the environmental performance of oil refineries, we find that corporate reports are of very limited value when seeking to compare and contrast levels of environmental performance at the site level, but that a significant body of useful information is provided by public registers such as the US TRI and the EU EPER. Drawing upon these data, we find significant variations in corporate environmental performance across the US and the EU, and we note the existence of significant correlations between higher levels of emissions and lower levels of employment and income in the areas where industrial facilities are located. We then discuss the relevance of our findings to broader debates on corporate environmentalism and corporate social responsibility. Copyright © 2006 John Wiley & Sons, Ltd and ERP Environment.     

Corporate governance and environmental performance and disclosures

In this study the relationships between good corporate governance practices and environmental performance and disclosure are examined. Firms that are among the major emitters of toxic emissions in the United States comprise the sample for the study. Pollution performance is measured using a methodology that includes both the toxicology of the emissions and the population density of the community. A corporate governance measure and a pollution disclosure evaluation that were previously presented in the accounting literature are utilized in the study to validate the main performance measure.The findings indicate that there is no relationship between good governance and good pollution performance. Additionally good governance is positively related to pollution disclosure while the correlation does not hold when governance was improved by SOX. The overall findings support legitimacy theory. This may indicate that the story about pollution performance is better than the actual outcome.     

Hybridizing Principles of the ELECTRE III Method with Case-Based Reasoning for a Travel Advisory System: Case Study of Thailand

Despite case-based reasoning (CBR) being one of the collaborative filtering approaches for a travel advisory system, the application of CBR to travel and tourism is still in a very early stage. Although some researches define a similarity function in CBR by using outranking relationship, there is a lack of research on how and why to combine outranking relationship with CBR. In this research, we address how to combine outranking relationship in the ELECTRE III with CBR for a case-based travel advisory system. In order to demonstrate the effectiveness of the hybrid model, the hybrid model is compared to the situation where the non-hybrid model was applied. In travel advisory mining, data were collected from travelers on the Chachoengsao province. Empirical results show that the hybrid model offers significantly better ranking performance than the CBR model derived from Euclidean metric.
