Logic Petri nets (LPNs) can describe and analyse the batch processing function and passing value indeterminacy in cooperative systems, and alleviate the state space explosion problem. However, the indeterminate data of logical output transitions cannot be described explicitly in LPNs. Therefore, Coloured Logic Petri nets (CLPNs) are defined in this paper. It can determine the indeterminate data of logic output transitions in LPNs, i.e., the indeterminate data can be represented definitely in CLPNs. A vector matching method is proposed to judge the enabling transitions and analyse CLPNs. From the marking equation and the proposed reachable tree generation algorithm of CLPNs, a reachable tree can be built, and reachable markings are calculated. The advantage of CLPNs can be shown based on the number of leaf nodes of the reachability tree, and CLPNs can solve the indeterminate data of logical output transitions. Finally, an example shows that CLPNs can further reduce the dimensionality of reachable markings. 相似文献

态度理论为地区形象(PI)和旅游目的地形象(TDI)的联合研究提供了一个平台。本文构建了一个理论上的地区形象背景下的旅游目的地形象结构方程模型。模型是一个具有因果关系的结构方程模型,包括8个潜变量和28个观测变量。以徐州为例,在运用SPSS15.0软件对数据进行信度检验的基础上,利用LISREL8.70软件对模型进行了验证性因子分析和路径分析。研究发现:(1)结构模型中各潜变量之间的路径与假定基本符合,模型的整体拟合性能良好;(2)旅游资源认知和旅游服务认知会对旅游意愿产生作用,这符合我们的传统理念;(3)地区特征和居民素质对旅游服务感知、目的地评价和旅游意愿三者均有效应,而地区竞争力和居民竞争力仅对旅游服务感知产生影响。 相似文献

ABSTRACTIn this article, we test whether the consumption pattern in Korea exhibits a time-inconsistent discounting behavior compared to the conventional exponential discounting. We derive the quasi-hyperbolic Euler equation and estimate it using the generalized method of moments (GMM). The estimation results show that Korean consumers exhibit a time-inconsistent quasi-hyperbolic discounting behavior in general, but the pattern of inconsistency in consumption behavior, in particular the degree of impatience, depends on the estimation period, in particular whether it includes financial crisis periods in 1997–98 and 2008–11. 相似文献

The present study develops and empirically tests a conceptual model of the organizational, strategic, and environmental drivers of export innovativeness. The relationship between export innovativeness and export performance is also examined. Using data collected from 168 small- and medium-sized direct exporters, we find that decentralization in decision making, export market orientation, information exchange and export market dynamism have a significant influence on exporting firms’ degree of innovativeness. Furthermore, export innovativeness has a significant positive effect on export performance. Several theoretical and managerial implications are derived from these findings. Directions for future research are also provided. 相似文献

The aim of our research is to investigate the important role of banks in the governance of companies listed in the Euronext 100 index. Primarily, this research seeks to examine the impact of a bank’s presence within a firm, as a creditor or shareholder, on firm performance, as well as the motivations of banks to acquire holdings, and whether the presence of a bank as a shareholder of a firm facilitates its access to bank loans. Empirical analyses are conducted with a sample of 86 nonfinancial institutions listed in the Euronext 100 index over the period 2008–2013 using the three-stage least squares method. The study shows, first, that the presence of a bank within a firm, as a creditor or shareholder, is positively related to firm performance. Moreover, the firm’s performance is an important determinant of the presence of bank shareholding. Finally, the presence of a bank as a shareholder of a firm does not facilitate its access to bank loans. 相似文献

An empirical analysis of the factors raising the interest in new shopping destinations 总被引:1,自引:0,他引:1
《Journal of Retailing and Consumer Services》2014,21(6):950-957
The relationship among the factors in the rising interest in new alternatives is empirically investigated in the context of shopping destination choice behavior. The hypothetical causal relationship is that the rising interest in new alternatives requires both active information search and considerable benefit, which is supported by the results of the mixture structural equation models using a data set containing revealed shopping behaviors and attitudes toward shopping destinations in the Tokyo metropolitan area: a lower level of satisfaction with the current choice set incites external information search for all subjects; however, the benefit of adding new alternatives affects the interest in new alternatives only in the group that engages in active information search. 相似文献

ABSTRACTThis research looks at the concept of brand heritage as a branded representation of the past and its influence on cognitive and affective responses. Although numerous items of research mention brand heritage, the subject still lacks conceptual clarity. This paper aims to address this gap and to build a scale measuring its perception by consumers. The literature review leads to a conceptualisation of brand heritage as the perception of a brand’s temporal management. Then, one qualitative and three quantitative studies facilitate the emergence and validate a three-dimensional scale of perceived brand heritage. A model demonstrates how brand heritage enhances brand credibility and personal nostalgia. This paper contributes to the apprehension of change and continuity in brand management, with potential extensions to other disciplines. 相似文献
