The evolution of new combinations: drivers of British maritime engineering competitiveness during the nineteenth century

This work is an attempt to explore early British steamship innovation during the 19th century from the point of view of innovation studies. The proposed analytical framework draws on neo-Schumpeterian and evolutionary economics for understanding the patterns and factors behind the phenomenon of technical change in the capital good under analysis. The thesis aims at filling a gap in the maritime economic and technological history literature, namely the issues connected to the process through which modern (mechanically-propelled, iron-hulled, screw-driven) ocean transportation emerged. Two inter-related research questions are addressed: how and why did steamships evolve in the course of the 19th century? In other words, the present research focuses on describing the dynamics of technological evolution and on identifying the key drivers of those developments. While the thesis includes a review of the relevant literature (Part I), the main work consists of original empirical research (Parts II and III). The bulk of this work primarily rests on the compilation of two new main bodies of quantitative and qualitative evidence. First, a previously unpublished dataset on the population and characteristics of steamers is used to measure the rate and direction of technical change in steamers. Second, previously unpublished archival material is used to reconstruct the innovation processes of marine engineers and naval architects and the civil society arrangements around them. The results suggest a number of stylised facts and institutional variables that have been subject to little discussion in the extant literature. On one hand, time-series and other statistical analyses suggest a technological “take-off” of steamship performance by the mid-19th century. This turning point, which was the outcome of a complex but rapid process of structural reconfiguration (the transition from wood-paddle to iron-screw as the new “dominant design”), occurred between the late 1830s and the late 1840s particularly among cargo traders and unsubsidised packets. On the other hand, documentary evidence shows that such technological breakthroughs were preceded and supported by a specific set of institutional innovations. These included the emergence of voluntary engineering associations, technical mass media and a not-for-profit ship classification society within the British national system of innovation. The thesis argues that the process of revolutionary technological innovation leading to the economically efficient long-haul merchant steamer cannot be separated from the rise of a vibrant interactive environment promoting learning, knowledge integration and technological accumulation, which may be called a “technological public sphere”

Telecommunications for the Needy: How needed are they?

Telecommunications, mobile and non-mobile, play a major role in our society, but their role as tools for escaping poverty remains a policy agenda still with room for progress both in Europe and around the World. Some groups in society, like the needy, have difficulties in accessing and using such technologies in ways that mirror the debates of the late 90s over the "digital divide". For some groups, like the needy, it would be more exact to address the concept of digital poverty rather than digital divide, because without access to telecommunications one might not have the same degree of opportunities to leave poverty or not to fall into poverty [34] [3] [4]. The goal of this paper is to scope the problem by departing from the Portuguese case study. Our research is empirical and highlights the telecommunication ownership and expenditures of the Portuguese population, and specially the most fragile segments within it. Such an effort is undertaken while not ignoring major issues of political economy of the contemporary globalizing networked society. Our main argument in this paper is that, if telecommunications are a needed tool for the lower income segments of the population, that is the needy, a debate around digital poverty associated to mobile telecommunications is needed in Europe too and to address such issues we need public policy commitments.needy, mobile telecommunications, digital poverty, digital divide, telecommunication policies

Advances and challenges in innovation studies

The article discusses recent advances and future challenges in innovation studies. First, it separately considers four main strands of research, studying innovation at the organisational, systemic, sectoral and macroeconomic levels. Then, considering the field as a whole, the article points to the existence of important neglected topics and methodological challenges for future research. In fact, several fundamental issues are still unexplored, such as the co-evolution between technological and institutional change; the role of demand; and the impacts of innovation on individual and collective welfare. There are also important methodological challenges, such as the need for more systematic interactions between the different levels of analysis; the importance of an interdisciplinary approach to the study of technological and institutional changes; and the search for a combination of contingent explanations based on case studies with general analytical results based on econometric and formal models.Innovation; Innovation management; innovation systems; innovation and growth

Wild cards, weak signals and prganizational improvisation

This paper addresses the need for reliable action guidelines that can be used by organisations in turbulent environments. Building on current conceptual and empirical research, we suggest an analytical approach for the management of surprising and potentially damaging events. In order to do so we use the wild card management system. Wild cards refer to sudden and unique incidents that can constitute turning points in the evolution of a certain trend or system. As the first of the two components of such a wild card system we advocate a weak signal methodology to take into account those wild cards that can be anticipated by scanning the decision environment. The second component, the nurture of improvisation capabilities, is designed to deal with ongoing crisis. This paper can be seen as part of a broader agenda on how to manage in conditions of continuous but unpredictable change.wild cards, weak signals, improvisation, minimal structures

A Delphi Approach to Boost an Open Innovation Policy

In this research paper we intend to find out whether open innovation approach may be a valid approach to the definition of innovation policy. To that, we use a method applied in various fields of study, including public policy and open innovation studies: the Delphi method. After the introduction (Section 1), we describe the Delphi method (Section 2) and the methodology used in this research (Section 3). The results of the application of the Delphi method are presented in Section 4, where we identify public policy priorities in an open innovation perspective. Then, we propose measures of public policy through which these priorities could be achieved (Section 5). Section 6 presents the main findings, concluding that the approach of open innovation may be considered for prioritization of innovation policy and policy measures

Education modulates brain maintenance in presymptomatic frontotemporal dementia

Objective Cognitively engaging lifestyles have been associated with reduced risk of conversion to dementia. Multiple mechanisms have been advocated, including increased brain volumes (ie, brain reserve) and reduced disease progression (ie, brain maintenance). In cross-sectional studies of presymptomatic frontotemporal dementia (FTD), higher education has been related to increased grey matter volume. Here, we examine the effect of education on grey matter loss over time. Methods Two-hundred twenty-nine subjects at-risk of carrying a pathogenic mutation leading to FTD underwent longitudinal cognitive assessment and T1-weighted MRI at baseline and at 1 year follow-up. The first principal component score of the graph-Laplacian Principal Component Analysis on 112 grey matter region-of-interest volumes was used to summarise the grey matter volume (GMV). The effects of education on cognitive performances and GMV at baseline and on the change between 1 year follow-up and baseline (slope) were tested by Structural Equation Modelling. Results Highly educated at-risk subjects had better cognition and higher grey matter volume at baseline;moreover, higher educational attainment was associated with slower loss of grey matter over time in mutation carriers. Conclusions This longitudinal study demonstrates that even in presence of ongoing pathological processes, education may facilitate both brain reserve and brain maintenance in the presymptomatic phase of genetic FTD
