Innovation, R&D and Productivity in the Costa Rican ICT Sector: A Case Study

This paper addresses the relationships between innovation, research and development (R&D) and productivity in domestic ICT firms in Costa Rica. Factors considered were the types of innovation outputs produced by domestic ICT firms, the relative importance of innovation inputs, the impacts of innovation on firm productivity, the protection of innovations, and impediments to innovation. While most firms engaged in all types of output and input innovations, they appear to be driven by retaining or increasing market share rather than increasing productivity. Half of firms do not formally protect the intellectual property created by their innovations, are not familiar with methods for protecting innovation or the availability of government grants for such purposes, and face barriers associated with the Costa Rican Patent Office. Other impediments include lack of knowledge about financial resources available and scarcity of human resources. There is also evidence of knowledge spillovers through worker mobility from multinationals operating in Costa Rica to domestic ICT firms

The economic geography of the meso-global spaces: integrating multinationals and clusters at the local-global level

This is an author's accepted manuscript of an article published in: “European Planning Studies"; Volume 21, Issue 7, 2013; copyright Taylor & Francis; available online at: http://dx.doi.org/10.1080/09654313.2013.733853[EN] The local global phenomenon literature is fragmented between the fields of international business and economic geography (EG). In the case of the latter, the literature, produced within the global production networks (GPNs) and global value chain frameworks, does not address the central role of firms, especially multinationals which co-locate and connect territories along GPNs. This paper develops a cross-field conceptual integration in order to enrich the EG perspective, using qualitative research methodology to test the framework. The results have important implications for scholars and policymakers.We are very thankful to the “Ministry of Economics” funding ECO2010:17318 and “Generalitat Valenciana” for its support in visiting the London School of Economics and Political Science (BEST 2011 grants)Hervás Oliver, JL.; Boix Domenech, R.

The role of a firm's absorptive capacity and the technology transfer process in clusters: How effective are technology centres in low-tech clusters?

This paper analyses how the internal resources of small- and medium-sized enterprises determine access (learning processes) to technology centres (TCs) or industrial research institutes (innovation infrastructure) in traditional low-tech clusters. These interactions basically represent traded (market-based) transactions, which constitute important sources of knowledge in clusters. The paper addresses the role of TCs in low-tech clusters, and uses semi-structured interviews with 80 firms in a manufacturing cluster. The results point out that producer–user interactions are the most frequent; thus, the higher the sector knowledge-intensive base, the more likely the utilization of the available research infrastructure becomes. Conversely, the sectors with less knowledge-intensive structures, i.e. less absorptive capacity (AC), present weak linkages to TCs, as they frequently prefer to interact with suppliers, who act as transceivers of knowledge. Therefore, not all the firms in a cluster can fully exploit the available research infrastructure, and their AC moderates this engagement. In addition, the existence of TCs is not sufficient since the active role of a firm's search strategies to undertake interactions and conduct openness to available sources of knowledge is also needed. The study has implications for policymakers and academia

Impact of industrial linkages on firm performance in development zones

This article investigates the effect of industrial linkages on firm performance in Chinese development zones, using Jiangsu Province as a case study. An ordered response model based on the dependent variable being ordinal was developed. The empirical results reveal an insignificant relationship between industrial linkages and firm performance. Our interpretation of this finding mainly lies with the global and domestic challenges that have changed the way participating firms operate and organize in the development zones of Jiangsu. When many other economic factors take precedence over industrial linkages in driving superior firm performance, firms feel it less important to get closer to their suppliers or customers, therefore weakening the impact of industrial linkages. Although this article primarily focuses on development zones in Jiangsu Province, the findings and discussion will provide insights for other development zones in China that may be, reviewing their development strategies because most of them have similar development problems

The Innovation Systems of Latin America and the Caribbean

It is now widely recognized that we live in a knowledge-based economy; in fact, knowledge is the driving factor behind productivity growth. The share of knowledge-intensive sectors in the world economy`s value-added and employment has been rising for a number of years. This trend is particularly pronounced in the developed countries, where by 1999 knowledge-based industries share of GDP was already above 50 percent, up from 45 percent in 1985 (OECD, 1999; OECD, 2000a). Furthermore, knowledge-driven innovation has become a decisive factor in the competitiveness of both nations and firms

Tau Causes Synapse Loss without Disrupting Calcium Homeostasis in the rTg4510 Model of Tauopathy

Neurofibrillary tangles (NFTs) of tau are one of the defining hallmarks of Alzheimer’s disease (AD), and are closely associated with neuronal degeneration. Although it has been suggested that calcium dysregulation is important to AD pathogenesis, few studies have probed the link between calcium homeostasis, synapse loss and pathological changes in tau. Here we test the hypothesis that pathological changes in tau are associated with changes in calcium by utilizing in vivo calcium imaging in adult rTg4510 mice that exhibit severe tau pathology due to over-expression of human mutant P301L tau. We observe prominent dendritic spine loss without disruptions in calcium homeostasis, indicating that tangles do not disrupt this fundamental feature of neuronal health, and that tau likely induces spine loss in a calcium-independent manner
