is international business good for companies the evolutionary or multi Stage Theory of internationalization vs the transaction cost perspective
Management International Review, 2007Co-Authors: Farok J ContractorAbstract:Abstract Abstract and Key Results This paper’s objective is to articulate, more precisely than has occurred in the past, the principal Theory rationales underlying the Multinationality/Performance (M/P) link, by examining each claim for the negative or positive benefits of internationalization, from the lens of the Theory of the firm and the multinational enterprise. A concurrent objective of this paper is to respond to critiques of M/P Theory and discuss methodology and operationalization problems in empirical testing. While international expansion of a firm will not necessarily always improve performance (during the initial international expansion Stage, or in cases where a firm may have over-internationalized), for the most part, over the considerable middle range of expansion, net positive benefits accrue from internationalization. Underlying Theory rationales are detailed in the paper. The results of over one hundred empirical studies over the past 30 years appear, on superficial examination, to be contradictory, but can be reconciled by the recently proposed 3-Stage or S-shaped general Theory.

a three Stage Theory of international expansion the link between multinationality and performance in the service sector
Journal of International Business Studies, 2003Co-Authors: Farok J Contractor, Sumit K KunduAbstract:It is generally assumed that the performance of a firm improves with greater multinationality. Yet recent empirical studies have shown both a U-shaped relationship (which suggests an initially negative effect of international expansion on performance, before the positive returns of international expansion are realized) and an inverted-U-shaped relationship (which suggests that international expansion beyond an optimal level is again detrimental to performance, and results in a negative slope). This paper proposes a new unified three-Stage Theory of international expansion that incorporates both concepts in a sigmoid hypothesis. It then tests this on data from 11 service industries, highlighting the difference between knowledge-based and capital-intensive service sectors.

network biology approach to epithelial mesenchymal transition in cancer metastasis three Stage Theory
Journal of Molecular Cell Biology, 2015Co-Authors: Hiroshi Tanaka, Soichi OgishimaAbstract:: Epithelial-mesenchymal transition (EMT) plays a critical role in promoting cancer metastasis. In this study, cancer EMT is considered as an overall structural change in the gene regulatory network (GRN), and its essential features are elucidated by the network biology approach. We first defined the state space of GRN as a set of all possible activation patterns of GRN, and then introduced the quasi-potential field into this space to show the relative stability distribution of each state. The quasi-potential was determined empirically by collecting gene expression profiles from public databases. Changes of GRN states during the EMT process were traced in the state space, by using time-course data of gene expression profiles of a cell line inducing EMT from the database. It was found that cancer EMT occurred in three sequential stable Stages, each of which formed a potential basin along the EMT trajectory. As confirmation, structural changes of GRN were estimated by applying the ARACNe algorithm to the same time-course data, and then applying master regulator analysis to extract the main regulations. Each group of master regulators was found to be alternatively active in the subsequent three Stages to cause overall structural changes of GRN during cancer EMT.

The social engineering personality framework
Proceedings - 4th Workshop on Socio-Technical Aspects in Security and Trust STAST 2014 - Co-located with 27th IEEE Computer Security Foundations Sympo, 2014Co-Authors: Sven Uebelacker, Susanne QuielAbstract:We explore Information and Communication Technology (ICT) security in a socio-technical world and focus in particular on the susceptibility to social engineering attacks. We pursue the question if and how personality traits influence this susceptibility. We use Cialdini's principles of influence to categorise social engineering attacks. First we show with a comprehensive literature review how existent research approaches social engineering susceptibility. Based on this review we construct suggestions for plausible relations between personality traits of the Five-Factor Model (Big 5) and the principles of influence. We propose our - at this Stage Theory-based - "Social Engineering Personality Framework" (SEPF) which we will evaluate in future empiric research. The characteristics of victims' personality traits in the SEPF will support and guide security researchers and practitioners in developing detection, mitigation, and prevention strategies while dealing with human factors in social engineering attacks.

the internationalization process of small and medium sized enterprises an evaluation of Stage Theory
Journal of Small Business Management, 2000Co-Authors: Hgj Gankema, Hr Snuif, Peter S ZwartAbstract:The aim of this study is to provide better insight into the internationalization process of small and medium-sized enterprises (SMEs). Using a five-year panel dataset and a relatively new technique, DEL analysis, the predictive validity of the export Stage concept of Cavusgil's innovation-related internationalization model (the I-model) is examined This Stage Theory conceptualizes the internationalization process using five Stages: a domestic marketing Stage, a pre-export Stage, an experimental involvement Stage, an active involvement Stage, and a committed involvement Stage. In addition, the time period to be considered in moving from one Stage to another is explicitly tested. The results suggest within certain limits that Cavusgil's Stage Theory holds for European manufacturing SMEs. According to the considered time frame, the results are slightly in favor of a two year-period.
