Service-oriented,sustainable, local food value chain – A case study

Many developing countries depend on tourism as their main engine for economic development, but sustainability is often a concern. In the absence of inter-sectorial linkages between tourism and other industrial sectors, opportunities for trickledown benefits to host communities are stymied. For decades, researchers have been contending with issues related to strengthening agriculture and tourism linkages as a strategy to maximize economic linkages. This service-oriented approach to the local food supply chain is posited as a new model in which agriculture and hotel linkages can be advanced. We collected data about local food hotel supply through interviews with key stakeholders. The findings from our exemplary case study confirm that strengthening inter-sectorial linkages have benefits for stakeholders. This case study suggests that there are opportunities for tourism policies that foster local food linkages with high-end accommodation properties as a strategy to spread the economic spin off from tourism and also to encourage youth involvement in sustainable tourism development.

Transformative service networks: cocreated value as well-being

Fundamental to emerging theories of value cocreation is a developing awareness that value emerges in networks. Service networks form to address issues for those in need, and value is conceived differently by the various constituents in the network. To represent this reality, a core service interaction, the reason for the construction of the network, is evaluated based upon a typology of value-creating interaction styles. Next, the potential impact on transformative value cocreation of various relationships in a service network is explored. To illustrate value cocreation from a network perspective, this paper develops research propositions assessing cocreated value in a health service network. Network factors regarding the structural and relationship properties of networks that advance the theory of value cocreation are proposed. Finally, suggestions for managers include ways to engage service network entities to enhance communication to foster a balanced, mutualistic relationship that optimizes cocreated value. Organizations need to better identify and activate customers' support networks in order to facilitate enhanced collaboration and communication.     

基于因果映射分析的高管战略逻辑研究

企业家的战略逻辑是企业家对外部知识进行感知和运用的复杂过程,它会对企业的战略方向产生直接影响。在不确定性增大、信息不完全的市场中,管理者如何对外部环境进行解读,对资源优化做出决策就显得非常重要。随着外部超竞争环境的不断加剧,管理者唯一的选择就是适时调整战略逻辑。因此,战略因果逻辑理论越来越受到理论学者和企业高层的重视。本文主要从内容分析法入手对管理者战略逻辑的转移做出一定分析和解释,并对高管认知的未来研究方向进行了展望。本文通过因果映射图来分析管理者的战略变革选择过程,发现高管的战略逻辑方向在外部环境影响下会随之产生变化。     

Do entrepreneurs from institutionally distinct countries apply different decision logic when internationalizing their companies? A multiple-case analysis

Literature on entrepreneurs’ decision logic has either focused on effectuation or causation, lacking comparison and analysis of logics when founders come from different institutional environments. This paper presents an exploratory study examining the behaviors, beliefs, and decisions of entrepreneurs (all typical drivers for new market entries), considering those institutional differences. Research was based on the comparison of two case studies of young software companies, one from Brazil and one from Germany, each founded by two entrepreneurs with similar academic and professional backgrounds. Results indicate that apparently, business environment affects founders’ decision logics with much more strength than the institutional environment.     

A fuzzy-based roadmapping model for enhancing high-tech small firms’ technological entrepreneurship capabilities: cases of Iran

ABSTRACT

Technology-based firms need to survive via technological changes. Technological entrepreneurship is concentrated on identifying and exploiting the tech-opportunities for creating product innovation. This paper introduces a fuzzy-based tool to promote innovation throughout firms in order to enhance technological entrepreneurship capabilities (TEC). The effort involves identifying components of TEC to develop the inference system, specifying the fuzzy relationship among these components, assessing the TEC in firms, and designing a TEC roadmap after a fuzzy-based gap analysis. Designed roadmaps introduce technological change priorities as a growth path to firms to move up along the ladder of competitiveness. Based on the results, a method for categorizing firms into four distinct levels that involve passive, reactive, proactive and innovative is introduced. Hence, firms have an action plan to enhance TEC from passive to innovative level in a time-based transition pathway.     

A dynamic decision support system for evaluating peer-to-peer rental accommodations in the sharing economy

Accommodation accounts for one of the biggest expenses while traveling, and deciding where to stay is often confusing and time-consuming. Fortunately, travelers have more options than ever before because of the substantial growth of the peer-to-peer (P2P) short-term rentals in the sharing economy. Designing a user-friendly system that considers travelers’ preferences in choosing the right accommodation can enhance customer satisfaction and increase profitability. We propose a dynamic decision support system based on the theory of multi-criteria decision making to assist travelers in personalizing their preferences and finding quality accommodations in the dominant P2P market that aligns with those preferences. We use the fuzzy best-worst method to measure the intensity of the user’s preferences and the fuzzy technique for order of preference by similarity to the ideal solution (TOPSIS) to score and evaluate alternative P2P rental properties. We present a case study in the P2P rental accommodations industry to demonstrate the applicability of the method proposed in this study.

Nonlinear multiple regression methods: a survey and extensions

This paper reviews some nonlinear statistical procedures useful in function approximation, classification, regression and time‐series analysis. Primary emphasis is on piecewise linear models such as multivariate adaptive regression splines, adaptive logic networks, hinging hyperplanes and their conceptual differences. Potential and actual applications of these methods are cited. Software for implementation is discussed, and practical suggestions are given for improvement. Examples show the relative capabilities of the various methods, including their ability for universal approximation. Copyright © 2010 John Wiley & Sons, Ltd.
