This paper presents a conceptual framework of Web users’ engagement in tourism information search for a comprehensive understanding of their integrated online and offline search behaviour. The information search experiences are characterised as a process constituting some common elements: prior knowledge and searching experiences, online searching strategies, processing and recording information, barriers to online searching, reasons for ending an online search, summarising information, exchanging information and searching for more information through other sources. Such behaviour goes beyond the scope of information searching and captures the other activities, including information processing, utilising and disseminating. The grounded theory research method is employed as an inductive investigative process in which the authors construct the framework by systematically collecting and analysing data. The aim of this research method is to build a theory. The data sets consist of both semi-structured in-depth interviews with subjects and their field observations based on online searching. A theoretical model incorporating 10 propositions is proposed for future testing. 相似文献

The present study examines the effect of using a mobile device on search and evaluation by a shopper in a brick-and-mortar store. A conceptual model that proposes inter-relationships between shopping goals, the amount and type of in-store mobile device use, and purchase outcomes is developed. Data from a national quota sample of 1034 mobile shoppers is used to test hypotheses derived from the proposed model. The findings provide several new insights into the impact of in-store mobile device use on the consumer decision journey in a brick-and-mortar store. Depending upon the shopping goals of the consumer, the use of a mobile device by shoppers in a brick-and-mortar store can either decrease or increase search, lead to more deferred purchases or in-store-now purchases, and more online or physical store purchases. The study is among the first to model the pathway to purchase for mobile device assisted shoppers in brick-and-mortar stores. 相似文献

Knoblock and Korf have determined that abstraction can reduce search at a single agent from exponential to linear complexity (Knoblock 1991; Korf 1987). We extend their results by showing how concurrent problem solving among multiple agents using abstraction can further reduce search to logarithmic complexity. We empirically validate our formal analysis by showing that it correctly predicts performance for the Towers of Hanoi problem (which meets all of the assumptions of the analysis). Furthermore, a powerful form of abstraction for large multiagent systems is to group agents into teams, and teams of agents into larger teams, to form an organizational pyramid. We apply our analysis to such an organization of agents and demonstrate the results in a delivery task domain. Our predictions about abstraction's benefits can also be met in this more realistic domain, even though assumptions made in our analysis are violated. Our analytical results thus hold the promise for explaining in general terms many experimental observations made in specific distributed AI systems, and we demonstrate this ability with examples from prior research.This research has been sponsored, in part, by the National Science Foundation under grants IRI-9015423 and IRI-9010645, by the University of Michigan Rackham Graduate School, and by a Bell Northern Research Postgraduate Award. 相似文献

企业边界变迁的产业组织演化 总被引:1,自引:0,他引:1
交易成本理论从成本角度分析企业边界形成与变迁,企业能力理论则采用比较利益的方法从收入角度分析.短期中,如果企业能力有很大的差异,交易成本降低,位于价值链中上下游的企业将趋于专业化生产;如果企业能力均匀分布,交易成本降低,对专业化生产没有影响.长期中,企业能力、交易成本、企业边界形成互动循环的演化机制,并且在竞争过程中实现自然选择,引起产业组织演化. 相似文献

Foreign direct investment is of increasing importance in the European Union. This paper estimates the effect of taxes on foreign
direct investment (FDI) flows and on three sub-components of these flows for the countries of the enlarged European Union.
The model in the spirit of gravity equations robustly explains FDI flows between the 25 member states. Sample selection needs
to be addressed in the estimation. We show that the different subcomponents of FDI should and indeed do react differently
to taxes. After controlling for unobserved country characteristics and common time effects, the top statutory corporate tax
rate of both, source and host country, turn insignificant for total FDI and investment into equity. However, high source country
taxes clearly increase the probability of firms to re-invest profits abroad and lower the percentage of debt financed FDI.
This might reflect profit re-allocation to avoid taxes. Market size factors have the expected signs.

This paper supports the view expressed by other authors that Ronald Coase’s ideas are often misrepresented in the academic
world. It restates some of Coase’s main findings with special emphasis on their relevance to processes taking place in Eastern
Europe. The goal of this paper is to revisit Coasean theory, to prove that oftentimes it is misrepresented and misinterpreted
and to show its relevance to some societies experiencing high transaction costs. The role of the legal system under high transaction
costs is stressed in its importance to transitional economies experiencing staggeringly high transaction costs. This paper
tries to shed light on the importance of transaction costs in the newly emerging markets and the respective role courts and
the government should play in directing economic resources.

意识形态是社会存在反映,也是一种重要的非正式制度。在回顾意识形态与企业家关系的相关理论的基础上,分析意识形态对企业家人力资本的影响路径。研究认为,意识形态对企业家人力资本的影响也由此可依次分为三个阶段:企业家对意识形态感知的认识阶段;企业家理性判断是否将共有意识形态纳入已有认知结构的评价阶段;共有的意识形态转化为个性化意识形态的实现阶段。论文结合广东温氏集团案例,揭示意识形态影响企业家人力资本的阶段性路径特征,提出针对意识形态对企业家人力资本影响的阶段性特点的阶段性战略,认识阶段增强企业家角色偏好,评价阶段降低企业家对意识形态判断的交易成本,实现阶段打造企业家声誉等,以期从而促进企业家人力资本提升。 相似文献

基于股权代理成本角度,采用2010年中国沪深两市发行A股的非金融类上市公司截面数据,并运用最小二乘法和logistic二元逻辑回归模型,研究了外部监督、股权激励与股权代理成本之间的关系。研究发现,股权代理成本高的公司更加倾向于寻求有效的外部监督,聘请高质量的会计师事务所;股权激励并不能起到完善公司内部治理机制的作用,反而会提高股权代理成本;股权激励会提高公司对外部审计质量的要求。 相似文献
