Objectives: The aim of the study was to compare preand post-operative blood flow through the internal jugular veins (IJVs) in patients with multiple sclerosis and chronic cerebrospinal venous insufficiency, who were subjected to endovascular treatment. The results were correlated with respect to changes in the quality of life. Methods: 144 MS patients underwent endovascular treatment of the IJV...

Received: 24 January 2006 Revised: 27 February 2007 Accepted: 20 March 2007 Online publication date: 19 July 2007 Abstract In this study we examine the contingent relationship between R&D intensity and performance of international joint ventures (IJVs) in an emerging market context. Based on Teece’s (1986) arguments regarding the appropriability of innovation, we identify two types of appropria...

The marketing performance of international joint ventures (IJVs) particularly of those in the Southeast Asian Economies has not received adequate attention from international business researchers and International Joint Ventures (IJVs) have become an important means of market entry for many firms, particularly those seeking entry into Asia. This study identifies the factors influencing the mark...

This paper examines the impacts of the knowledge transfer capacity of multinational enterprises (MNEs) on the extent to which international joint ventures (IJVs) acquire technology. Although MNEs’ capability to transfer knowledge is a key catalyst for IJVs to learn new information, extant literature currently sheds light on only student’s absorptive capacity and neglects teacher’s fundamental a...

Article history: Received 23 February 2012 Received in revised form 13 July 2013 Accepted 14 July 2013 Available online 9 August 2013 In international joint ventures (IJVs), management control exerted by parent firms is fundamental since it can direct employees' activities to strive for the overall goals, to safeguard parent firms' idiosyncratic investments and to decrease opportunistic behavio...

Real options theory predicts that international joint ventures (IJVs) confer valuable growth options to firms, yet there has been no direct evidence on whether firms actually capture growth option value from such investments or under what conditions. We bridge the gap between theory and evidence by empirically testing this prediction, and we also develop the theoretical arguments that an IJV’s ...

Internal jugular vein (IJV) is one of the central veins and is the largest vein in neck. The application of endovascular stent placement in internal jugular vein stenosis (IJVS) is rare. Here, we studied the feasibility and curative effect of the treatment of IJVS by stent placement. A total of 3 patients with IJVS were diagnosed by angiography and treated with stent placement. Anticoagulant th...

BACKGROUND Recent evidence has indicated an association between chronic cerebrospinal venous insufficiency (CCSVI) and multiple sclerosis. Small internal jugular veins (IJVs) (with a cross-sectional area of less than 0.4 cm²) have been previously described as difficult to catheterize, and their presence may potentially affect cerebrospinal venous drainage. In this blinded extracranial color-Dop...

This article examines the relationship between foreign parent control and International Joint Venture (IJV) performance over the lifecycle of the IJV. Following Geringer and Hebert (1989); Glaister, Husan, and Buckley (2005), Nguyen and Larimo (2008), the paper conceptualizes foreign parent control across three dimensions including mechanism, focus, and extent. The empirical evidence is based o...

International joint ventures (IJVs) have become an important source of critical knowledge for multinational enterprises, but little is known about how can be effectively transferred to parent firms when the potential interpartner opportunism still exists. Drawing on attachment theory, we study boundary-spanning commitments IJVs may help mitigate and facilitate effective transfer parents. Specif...
