Cult Places and Cultural Change in Republican Italy
No full textThis scholarly study throws a new light on the Roman impact on religious structures in Republican Italy. In the last four centuries BC, Italy went through immense changes. The Apennine and Adriatic areas were originally inhabited by various 'Italic' tribes and characterised by a specific non-urban societal organisation, in which cult places had a pivotal function. From the fourth century BC onwards the area was gradually incorporated by Rome, profoundly altering its geopolitical make-up. The author not only investigates the changing social and political function of cult places in non-Roman Italic society, he also highlights the importance of cult places and religious rituals for new Roman communities in the conquered areas. This research thus opens new perspectives on the issue of the 'religious romanisation' of Italy by arguing for a strong Roman impact also in non-urbanised areas. Tesse Stek bases his study on the analysis of archaeological, literary and epigraphic evidence from rural cult places in Central and Southern Italy, including field work on the Samnite temple of S. Giovanni in Galdo

Mapping high R&D city-regions worldwide: A patent heat map approach
No full textA methodology for identifying high R&D city-regions worldwide using patent data is presented. A heat map (kernel density estimation) approach is used which allows city-regions to be identified in areas with a high patenting intensity, a proxy for high R&D expenditure. The methodology is independent of any pre-existing administrative boundaries and it can therefore be applied to identify sub-national concentrations of R&D expenditure worldwide. This is an important advantage compared to other statistical data which is often only available at the national level. The results provide insight into the changing worldwide spatial distribution of R&D expenditure between 1997 and 2011, including the rapid rise of Asian R&D city-regions as well as less dramatic shifts among European and North American city-regions. The results also highlight some challenges of identifying high R&D city-regions and estimating R&D expenditure using patent data, and the existence of very large high R&D city-regions which encompass multiple cities. Some suggestions for improvement and further research are also proposed.Economics of Technology and Innovatio
Identifying spatial technology clusters from patenting concentrations using heat map kernel density estimation
No full textIn this paper a methodology for identifying and delineating spatial technology clusters based on patenting concentration is developed. The methodology involves the automated geocoding of patent inventor addresses, the application of a home bias correction factor and a sensitivity analysis to determine the optimal parameters of the kernel density estimation interpolation distance and the minimum concentration threshold to identify clusters. The methodology’s performance is compared to a number of other cluster identification methods and it is validated across 18 individual sectors, including mature broad-based high-technology sectors and emerging niche sustainable energy technology sectors. The results suggest that the performance of the methodology exceed that of alternative cluster identification methods, although there is some variation in performance between different sectors. This demonstrates that the methodology provides researchers, practitioners and policy makers with a useful tool to gain insight into the spatial distribution of sectoral innovation activity at a global scale and sub-national regional level and to monitor changes over time, thereby supplementing more readily available global statistical data which is available at the national level.Economics of Technology and Innovatio
The Development of Technology Cluster Innovation Performance: Health and Sustainable Energy
No full textMotivation. The sustainability technology sectors, encompassing health and sustainable energy technology, play a critically important role in addressing global challenges such as climate change and ageing populations, which require a transition to a low or zero-carbon energy system, and sustainable and affordable healthcare. While these problems cannot be resolved by technological solutions alone, technology plays an important part in addressing them. Innovation, climate change, public health and the need for sustainable industrialization and economic growth are also part of the Sustainable Development Goals of the United Nations, further highlighting their global importance. Another motivation for the study, specifically from a European perspective, is a concern over the long-term economic competitiveness of Europe, which appears to be lagging behind the United States and certain Asian countries. This concern is a driver of the European Union’s current science and technology policy, including its multi-billion euro Horizon Europe initiative and Smart Specialization strategies for European regions. Research Question and Knowledge Gaps. The main research question addressed in this dissertation is: How are the dynamic spatial distribution and innovation performance patterns of sustainability technology clusters influenced by cluster characteristics, such as agglomeration and knowledge networks, and sectoral differences? Although there is an extensive literature on evolutionary economic geography, innovation systems, and global innovation diffusion, these theories often lack specificity with regard to particular technology sectors. Relatively little is known about the spatial distribution, cluster characteristics, and cluster innovation performance in the sustainability technology sectors. There are three main knowledge gaps: (i) the global spatial distribution and knowledge networks of technology clusters and their changes over time, (ii) the association between cluster innovation performance and various cluster characteristics, and (iii) the extent to which the aforementioned factors are influenced by socio-technological transitions and other sectoral differences. These knowledge gaps are addressed with a novel empirical approach to cluster identification, the measurement of cluster characteristics and the modeling of innovation performance…Economics of Technology and Innovatio
Bubble street behaviour in a highly viscous laminar bubble column
No full textIn this research project the bubble street behaviour and stabihty of a high viscous (77 =31, 47, 61, 99 mPas) laminar bubble column is studied (diameter 23 cm, height 80 cm), using gas flow rates of Qd = 23.6 and 36.7 cm^3/s. The Hquid is a solution of PVP powder in tap water. The Reynolds numbers, based on the maximum liquid velocity and the bubble street diameter, vary from 190 to 540. The investigation has two goals. The first is to compare the Rietema k Ottengraf theory [1] concerning a circulating steady state bubble column to experimental results. The second is to make an inventory of the transition traject to a chaotic laminar ('normal') bubble column. Laser Doppler measurements were performed on the hquid, together with visual observations. The high concentration of PVP-particles solved in the liquid causes a large standard deviation in the velocity measurements, while the mean values are unbiased. In the circulating regime the flow has quite a smooth proflle with a very regular bubble pattern. The bubbles move via fixed patterns through the liquid. However, both the axial velocity and the hquid fiow rate increase with height. Assuming an axisymmetrical flow, the liquid fiow must have a radial component, which means that the flow cannot be one dimensional. The radial flow causes the bubbles to move to the centre of the column. The position of the zero velocity in the axial hquid profile is almost constant over the height, even though the bubble street (based on the bubble positions) narrows. In the transition regime the fiow develops from a bubble street in the lower part of the column to a chaotic regime in the upper part. Two mechanisms control the transition. The drafting-kissing-tumbhng mechanism according to Fortes et al. [2] for bubble pairs is the first. The second is a mechanism that causes waving and oscillating bubble chains.Kramers Laboratorium voor Fysische TechnologieApplied Science
The influence of international research interaction on national innovation performance: A bibliometric approach
No full textInternational research interactions, specifically interpersonal collaboration, institutional collaboration and within multinational corporation (MNC) collaboration, have been increasing since the 2000s as a result of globalization and rising technological complexity. Yet the impact of international research interactions (IRIs) on national innovation performance is ambiguous. In this study patent-based bibliometric indicators are developed to investigate the influence of different types of IRI on innovation performance using bibliometric data covering eight knowledge intensive manufacturing sectors and 32 countries during the 2003–2008 period. This sector-based approach avoids some of the problems of using patents as innovation indicators, like varying patenting propensities across sectors by comparing the same sectors across countries. In the study a knowledge production function is estimated for each sector, with patents serving as an indicator of knowledge output. The overall results suggest an absence of positive influence of IRI on innovation performance, and sometimes even a negative influence pointing to ‘reversed knowledge flows’. But the pattern is nuanced and differs per sector and type of collaboration. For example, interpersonal collaboration has a negative or no effect on innovation performance depending on the sector, and institutional collaboration has no effect on innovation performance. Within MNC collaboration has a positive influence on innovation performance in the chemicals and pharmaceuticals sectors, but a negative effect or no effect in other sectors. Computers are an exceptional sector in that the influence of IRI depends on the absolute size of the sector in the domestic economy. The paper concludes with the theoretical relevance of these findings and some policy implications are also discussed.Accepted Author ManuscriptEconomics of Technology and Innovatio
Measuring Helix Interactions in the Context of Economic Development and Public Policies: From Triple to Quadruple and N-Tuple Helix vs. N-Tuple and Quadruple Helix to Triads
No full textQuadruple collaboration has risen rapidly in place of the traditional triple helix model of institutional collaboration between universities, governments, and companies. Loet Leydesdorff and Helen Lawton Smith (2022) approach this challenge by aiming to resolve the issue of evaluating and analyzing various quadruple and n-tuple helices. This article seeks to recognize the increasing complexity of new and developing issues in quadruple and n-tuple helices as a response to their research. Higher order helices raise a number of important scientific difficulties, including conceptual and practical issues. The goal of this contribution is to highlight some of the major challenges involved with researching multiple helixes in terms of knowledge innovation, as well as to offer some alternative areas for future research on n-tuple helices measurement.Economics of Technology and Innovatio
