Inter-firm complementarities in R&D : a re-examination of the relative performance of joint ventures

We compare duopoly outcomes between two alternative modes of research and development (R&D), viz. independent R&D and non-cooperative research joint ventures (RJVs), when there are complementarities between firm-specific R&D resources. When complementarity is high, RJVs lead to higher technological improvement and the reverse holds for low complementarity. In the intermediate range, the comparison depends on the relative imperfection in spillovers afflicting independent R&D. In sharp contrast to results on cooperative RJVs, non-cooperative RJVs lead to higher technological improvement when spillovers affecting independent R&D are low; the reverse holds for high spillovers. When RJVs yield higher technological improvement, they also yield higher industry profit and social welfare.

Inter-firm knowledge diffusion, market power, and welfare

We propose an infinite-horizon quantity-setting differential game with learning spillovers and organizational forgetting to analyze the optimal management decisions affecting the evolution of the stock of know-how, and, in turn, the dynamics of productive efficiency. Specifically, we study the long run impact of inter-firm knowledge diffusion on market power, i.e. the ability of a firm to raise the price above the marginal cost, and welfare. We consider two types of processes through which knowledge is acquired: (i) passive learning, or learning-by-doing, where managers do not actively invest in information and (ii) active learning, or learning-by-investing, where managers acquire new and additional information through specific investments in human capital. We show that: under (i), knowledge diffusion reduces market power; under (ii), knowledge diffusion reduces market power as long as learning spillovers are sufficiently important. From a welfare viewpoint, we also show that: under (i), knowledge diffusion is always welfare-enhancing; under (ii), weak spillovers are required in order for knowledge diffusion to be welfare-enhancing.

The role of trust in joint venture control : a theoretical framework

This paper develops a theoretical framework and a number of propositions for systematically studying the role of trust in the control and performance of Joint Ventures, a prominent form of inter-firm alliance. The proposed framework is more complete than the frameworks available in the extant literature because it incorporates both transaction related risks and the partner related risks which are likely to impact on the reliance on particular control patterns. Partner-related risks in joint ventures are represented by the level of inter-partner trust, while transaction-related risks are represented by the Transaction Cost Economics (TCE) variables of asset specificity, task complexity, performance measurability, and environmental uncertainty.

The framework also links one of the established management control typologies (i.e., behaviour, outcome, and social) to two of the alliance control patterns (bureaucratic-based pattern, and trust-based pattern) identified in the literature on alliance control.

Trust in strategic alliances: what does it mean and how is it built?

Informed by social exchange theory (SET) this study examines the role of trust in strategic alliances. Interviews were conducted with 17 participants who were strategic alliance managers in their organization. The study finds that trust is important to strategic alliance managers, and without it alliance managers would find it difficult to keep their alliance going. Trust is built over time, and based on the past experiences that the alliance manager has with their partner. The study found that prior networks, timely and appropriate communication and information exchange, fairness preservation and inter-firm adaptation were important in developing trust in the strategic alliance.

A trilogy on discontinuous innovation. Part I : search

In this article we discuss the concept of Discontinuous Innovation (DI) and how it differs from incremental (or steady-state) innovation. We propose a model to conceptualise the different aspects of DI and discuss the complex nature of the DI process through an investigation of previous literature, and propose a sequence of articles roughly following the key components as described in the conceptual model, beginning with aspects of ‘search’. We then describe an on-going multi-national action research program established to investigate DI through the development of learning networks of firms in several European nations and Australia. The research progress to date is outlined and initial results of analysis on both quantitative and qualitative data collected thus far is used to explore how companies go about searching for clues or ideas about potential discontinuous innovations, which may either create competitive advantage for, or threaten the survival of the business. Key outcomes of the research to date include the identification of the most common search strategies within the participating companies and some descriptive analysis on just how these strategies are implemented in targeted firms. Finally we describe the proposed future research program and the two papers to follow completing the planned three part series on Discontinuous Innovation.

Building trust in cross-sector R&D collaborations : the role of credible commitments

This paper reports selected findings from a study of one form of cross-boundary relationship: cross-sector R&D collaboration under the Australian Cooperative Research Centre (CRC) Programme. The study sought to explain project partners’ collaboration experience using a theoretical model which was empirically tested with a survey of CRC project leaders. It was hypothesised (H1) that the higher the level of relational trust (measured, following Sako, in terms of contractual, competence, and goodwill trust) amongst the partners in a collaborative project team, the more positive would be the partners’ experience of the project. The construct of credible commitments (the making of pledges, or the economic equivalent of the taking of hostages, which bind partners to a relationship) was posed in the model as an antecedent of relational trust. Accordingly it was hypothesised (H2) that the more that credible commitments are made by the project partners, the higher would be the level of relational trust between them. Data from the achieved sample (n = 156, 51% response rate) were analysed using PLS Graph. The results of the analysis provided support for hypothesis 1 but not for hypothesis 2. It was concluded that this latter finding could be due to the specific context of the study (cross-sector R&D collaborations under the CRC Programme differ markedly from inter-firm strategic alliances), or it could be due to the complex nature of credible commitments which was not adequately captured by our measure of this construct. Further research is required in this area to clarify the nature credible commitments, and the circumstances under which they contribute to a spiral of rising trust, in different cross-boundary contexts.

How do critical care nurses define the discharge planning process?

Background: Professional, political and organisational factors have focused attention on the discharge planning process in the Victorian health care sector. Discharge planning for patients, as part of continuity of care, is seen as a key concept in the delivery of nursing care. However, there is no question that discharge planning has emerged as a complex area of practice, and is, perhaps, most complex in the critical care area.

Aim: The study reported here is part of a larger thesis exploring critical care nurses’ perceptions and understanding of the discharge planning process in the health care system in the state of Victoria, Australia. As part of the survey participants were asked to define discharge planning as it related to the critical care environment in which they worked.

Methods: Utilising an exploratory descriptive approach, 502 Victorian critical care nurses were approached to take part in the study. The resultant net total of 218 participants completed the survey, which represented a net response rate of 43.4%. The data were analysed using quantitative and qualitative methodologies.

Findings: Three common themes emerged. A significant number of participants did not believe that discharge planning occurred in critical care, and therefore, thought that they could not provide a definition. There was uncertainty as to what the discharge planning process actually referred to in terms of discharge from critical care to the general ward or discharge from the hospital. There was an emphasis on movement of the patient to the general ward, which was considered in three main ways by first, getting the patient ready for transfer; second, ensuring a smooth transition to the ward and third, transfer of the patient to the ward often occurred because the critical care bed was needed for another patient.

Conclusion: The findings presented here suggest at a nursing level, the discharge planning process is not well understood and some degree of mutual exclusivity still remains. There is a need for further education of critical care nurses with regard to the underlying principles of the discharge planning process.

Guest editorial : In Journal of networks, v.7 n.3

Networking of computing devices has been going through rapid evolution and thus continuing to be an ever expanding area of importance in recent years. New technologies, protocols, services and usage patterns have contributed to the major research interests in this area of computer science. The current special issue is an effort to bring forward some of these interesting developments that are being pursued by researchers at present in different parts of the globe. Our objective is to provide the readership with some insight into the latest innovations in computer networking through this. This Special Issue presents selected papers from the thirteenth conference of the series (ICCIT 2010) held during December 23-25, 2010 at the Ahsanullah University of Science and Technology. The first ICCIT was held in Dhaka, Bangladesh, in 1998. Since then the conference has grown to be one of the largest computer and IT related research conferences in the South Asian region, with participation of academics and researchers from many countries around the world. Starting in 2008 the proceedings of ICCIT are included in IEEExplore. In 2010, a total of 410 full papers were submitted to the conference of which 136 were accepted after reviews conducted by an international program committee comprising 81 members from 16 countries. This was tantamount to an acceptance rate of 33%. From these 136 papers, 14 highly ranked manuscripts were invited for this Special Issue. The authors were advised to enhance their papers significantly and submit them to undergo review for suitability of inclusion into this publication. Of those, eight papers survived the review process and have been selected for inclusion in this Special Issue. The authors of these papers represent academic and/or research institutions from Australia, Bangladesh, Japan, Korea and USA. These papers address issues concerning different domains of networks namely, optical fiber communication, wireless and interconnection networks, issues related to networking hardware and software and network mobility. The paper titled “Virtualization in Wireless Sensor Network: Challenges and Opportunities” argues in favor of bringing in different heterogeneous sensors under a common virtual framework so that the issues like flexibility, diversity, management and security can be handled practically. The authors Md. Motaharul Islam and Eui-Num Huh propose an architecture for sensor virtualization. They also present the current status and the challenges and opportunities for further research on the topic. The manuscript “Effect of Polarization Mode Dispersion on the BER Performance of Optical CDMA” deals with impact of polarization mode dispersion on the bit error rate performance of direct sequence optical code division multiple access. The authors, Md. Jahedul Islam and Md. Rafiqul Islam present an analytical approach toward determining the impact of different performance parameters. The authors show that the bit error rate performance improves significantly by the third order polarization mode dispersion than its first or second order counterparts. The authors Md. Shohrab Hossain, Mohammed Atiquzzaman and William Ivancic of the paper “Cost and Efficiency Analysis of NEMO Protocol Entities” present an analytical model for estimating the cost incurred by major mobility entities of a NEMO. The authors define a new metric for cost calculation in the process. Both the newly developed metric and the analytical model are likely to be useful to network engineers in estimating the resource requirement at the key entities while designing such a network. The article titled “A Highly Flexible LDPC Decoder using Hierarchical Quasi-Cyclic Matrix with Layered Permutation” deals with Low Density Parity Check decoders. The authors, Vikram Arkalgud Chandrasetty and Syed Mahfuzul Aziz propose a novel multi-level structured hierarchical matrix approach for generating codes of different lengths flexibly depending upon the requirement of the application. The manuscript “Analysis of Performance Limitations in Fiber Bragg Grating Based Optical Add-Drop Multiplexer due to Crosstalk” has been contributed by M. Mahiuddin and M. S. Islam. The paper proposes a new method of handling crosstalk with a fiber Bragg grating based optical add drop multiplexer (OADM). The authors show with an analytical model that different parameters improve using their proposed OADM. The paper “High Performance Hierarchical Torus Network Under Adverse Traffic Patterns” addresses issues related to hierarchical torus network (HTN) under adverse traffic patterns. The authors, M.M. Hafizur Rahman, Yukinori Sato, and Yasushi Inoguchi observe that dynamic communication performance of an HTN under adverse traffic conditions has not yet been addressed. The authors evaluate the performance of HTN for comparison with some other relevant networks. It is interesting to see that HTN outperforms these counterparts in terms of throughput and data transfer under adverse traffic. The manuscript titled “Dynamic Communication Performance Enhancement in Hierarchical Torus Network by Selection Algorithm” has been contributed by M.M. Hafizur Rahman, Yukinori Sato, and Yasushi Inoguchi. The authors introduce three simple adapting routing algorithms for efficient use of physical links and virtual channels in hierarchical torus network. The authors show that their approaches yield better performance for such networks. The final title “An Optimization Technique for Improved VoIP Performance over Wireless LAN” has been contributed by five authors, namely, Tamal Chakraborty, Atri Mukhopadhyay, Suman Bhunia, Iti Saha Misra and Salil K. Sanyal. The authors propose an optimization technique for configuring the parameters of the access points. In addition, they come up with an optimization mechanism in order to tune the threshold of active queue management system appropriately. Put together, the mechanisms improve the VoIP performance significantly under congestion. Finally, the Guest Editors would like to express their sincere gratitude to the 15 reviewers besides the guest editors themselves (Khalid M. Awan, Mukaddim Pathan, Ben Townsend, Morshed Chowdhury, Iftekhar Ahmad, Gour Karmakar, Shivali Goel, Hairulnizam Mahdin, Abdullah A Yusuf, Kashif Sattar, A.K.M. Azad, F. Rahman, Bahman Javadi, Abdelrahman Desoky, Lenin Mehedy) from several countries (Australia, Bangladesh, Japan, Pakistan, UK and USA) who have given immensely to this process. They have responded to the Guest Editors in the shortest possible time and dedicated their valuable time to ensure that the Special Issue contains high-quality papers with significant novelty and contributions.

Effect of aluminum on the corrosion resistance of low-alloy steel in 10wt% sulfuric acid solution

The aqueous corrosion behavior of low-alloy steel with aluminum contents was examined in a 10 wt% H₂SO₄ (pH 0.13) solution using electrochemical techniques and surface analyses. The corrosion resistance of the new alloy steel was evaluated in terms of electrochemical parameters, such as passive current density, film, and charge transfer resistances. The results showed that a high Al content in the steel imparted better passivation behavior resulting in a lower corrosion rate. It related to the enrichment of iron carbonate and hydrocarbon by the dissolution of the carbide phase.

Regional integration 2.0 : facilitating regional integration and development with collaborative technologies

The current global economic instability and the vulnerability of small nations provide the impetus for greater integration between the countries of the South Pacific region. This exercise is critical for their survival. Past efforts of regional integration in the South Pacific have mostly failed. However, today’s IT collaborative capabilities provide the opportunity to develop a shared IT infrastructure to facilitate integration in the South Pacific. In developing an IT-backed model of regional integration, this study identifies and reports on the antecedents of the current stage for integration in the Pacific. We conducted interviews with twenty five individuals from various sectors and find that while most respondents were optimistic about the potential of IT-backed regional integration, significant challenges exists. The study identifies and discusses these challenges providing policy implications to stakeholders in the regional integration process. The findings will assist in suggesting a model of regional integration 2.0 for the Pacific region.

Knowledge management view of environmental sustainability in manufacturing SMEs in the Philippines

This study highlights the role of knowledge management (KM) in enabling small and medium enterprises (SMEs) in a manufacturing industry in a developing country to engage in environmentally sustainable business. Drawing on the knowledge-based view of the firm, it argues that resource-constrained SMEs rely on their relational capital to augment their capability to innovate in order to find better and environmentally sound ways of doing business. However, SMEs need to harness their KM orientation in order to leverage the knowledge-based resources emanating from their relational capital towards building their innovation capability. This capability is essential in integrating effective environmental management practices in business. The findings from our analysis of data from a survey of 241 manufacturing SMEs in the Philippines support these hypotheses and underscore the importance of developing an organisational capability to engage in KM in order to adopt sustainable business practices. The implications of the findings are also discussed.
