International collaboration in research activities has been highlighted because it offers higher productivity and has a greater impact than non-international collaboration. Given the importance of international collaboration, researchers make strategic decisions on their collaboration modes in the light of their environments and the expected trade-offs, since long-distance research collaboration entails both costs and benefits. By using national data at the project level, this paper examines the possible factors in international collaboration in various research areas, mainly focusing on research activities by universities. Our empirical results suggest that substantial financial and attentional resources, academic excellence, individual motivation, and active informal communication play significant roles in accomplishing international collaboration. Additionally, this paper refines the understanding of the role of communication and policy in ensuring the most effective use of research resources, helping research managers to promote collaboration in an appropriate decision-making context. © The Author 2013.

Purpose - The purpose of this paper is to reveal the core determinants and adoption patterns of the major enterprise information systems. Design/methodology/approach - This study incorporated the core representative and meaningful explanatory variables in the major previous literatures and analyzes the core determinants of businesses' adoption of the essential information systems and the substitutionary patterns among them, using a Bayesian multivariate probit model, which is based on McFadden's random utility model and capable of handling multiple response data. Findings - It was found that not only factors from the classical technological diffusion viewpoint but also factors such as organizational tools and strategic behaviors play an important role in firms' adoption of information systems. Specifically, epidemic effect generally outweighs size effect, and putting more effort into the intensity of information strategy planning is more influential than the hiring of a professional chief information officer. On the other hand, such variables as age of the firm, labor intensity, and number of PCs per person generally have no significant impacts. Finally, a relatively strong complementary relationship exists between enterprise resource planning and customer relationship management adoption, and between e-buy and groupware adoption. Originality/value - The results presented in this paper have important implications for firms on a minimal budget that want to maximize their productivity through the adoption of information systems. They also provide important information for government policymakers whose job it is to design strategies for the successful deployment of information systems. © 2011 Emerald Group Publishing Limited.

Just as standards wars over formats had characterized VCRs upon introduction to the market, the next-generation DVD standards war between Blu-Ray and HD-DVD lasted 6 years before Blu-Ray won the contest. Beginning with stated preference data drawn from a structured conjoint survey conducted before Blu-Ray became the de facto standard of the next-generation DVD format, we estimate consumer preferences on digital video players. A Bayesian mixed-logit model is used and market share simulations are conducted under various scenarios based on the estimated parameters from Bayesian mixed-logit model to surmise the future South Korean digital video-player market. Results indicate that consumers feel that network size and title availability are more important than hardware-related facets of the product, such as definition and storage capacity. The level of title availability and price of the Blu-Ray player for Blu-Ray's dominance over DVD will dramatically vary by the penetration rate of DVD players. © 2011 Blackwell Publishing Ltd.

This paper suggests an empirical framework to classify research collaboration activities with developed indicators that carry on a previous theoretical framework (Wagner [Science and Technology Policy for Development,Dialogues at the Interface, 2006]; Wagner et al. [Linking effectively: Learning lessons from successful collaboration in science and technology. DB-345-OSTP, 2002]) by employing the Gaussian mixture model, an advanced probabilistic clustering analysis. By further exploring the method upon a profound evidence-based reflection of actual phenomena, this paper also proposes an exploratory analysis to manage and evaluate research projects upon their differentiated classification in a preceding perspective of research collaboration and R & D management. In addition, the results show that international collaboration tends to be associated with more evenly committed collaboration, and that collaboration featuring a higher degree of funding or dispersed commitments generally results in larger outcomes than research clustered on the opposite side of the framework. © 2012 Akadémiai Kiadó, Budapest, Hungary.

Given the high priority accorded to research collaboration on the assumption that it yields higher productivity and impact rates than do non-collaborative results, research collaboration modes are assessed for their benefits and costs before being executed. Researchers are accountable for selecting their collaboration modes, a decision made through strategic decision making influenced by their environments and the trade-offs among alternatives. In this context, by using bibliographic information and related internal data from the Korea Institute of Machinery and Materials (KIMM, a representative Korean government institute of mechanical research), this paper examines the suggested yet unproven determinants of research collaboration modes that the SCI data set cannot reveal through a Multinomial Probit Model. The results indicate that informal communication, cultural proximity, academic excellence, external fund inspiration, and technology development levels play significant roles in the determination of specific collaboration modes, such as sole research, internal collaboration, domestic collaboration, and international collaboration. This paper refines collaboration mode studies by describing the actual collaboration phenomenon as it occurs in research institutes and the motivations prompting research collaboration, allowing research mangers to encourage researchers to collaborate in an appropriate decision-making context. © 2011 Akadémiai Kiadó, Budapest, Hungary.
