This research examines the evolution of technology within the optics industry. Optics is the study of the behaviour and transmission of light. We identify core optical technologies using a list of optics-related keywords and US patent data. Sub-class data, spanning 3,000 technology fields, enabled the characterization of different branches of knowledge production within optics. The “map equation” is used to represent the evolution of these technological branches across centres of optics innovation in the US. Analysis shows that individual cities specialize in the creation of different kinds of optics technologies, and these technologies take on different evolutionary pathways over time.  相似文献

The paper analyses changes experienced by Spain as a European peripheral region in the automobile global value chain (GVC). Our attention is focused on both spatial concentration of value‐added and high‐skill activities, and generation of technology in the components industry. The analysis of plants set up (investments) and relocated (divestments) by multinationals (MNEs) between 2001 and 2010 shows that Spain is no longer a place for labour‐intensive activities and standardized processes using simple technologies in comparison with other peripheral regions. However, the continuing majority presence of foreign‐owned companies is limiting decision power for generating and transferring technology, concentrating it mainly in the areas in which Spanish MNEs are specialized.  相似文献

The United States has experienced swings of public and private operation of its water services for more than 150 years. This paper examines the most recent swing, that of remunicipalization. We argue that much of this remunicipalization is taking place for ‘pragmatic’ reasons related to cost savings and service quality, but there are also signs of more ‘politicized’ forms of water remunicipalization taking place, similar to efforts elsewhere in the world where the process has often involved heated ideological debates and mass mobilizations. Combined with a growing politicization of other social, economic, and environmental issues in the US, water remunicipalization could become more politicized in the future, but a fragmented ‘pro-public’ movement, combined with ongoing efforts to outsource water services and growing resistance to remunicipalization from private water companies, may constrain this potential.  相似文献

This study draws upon concepts in landscape research and environmental justice to examine the association between community poverty and environmental violations that occurred between 2002 and 2008 across 110 coal strip mining operations located within the United States. Multivariate results suggest that residential poverty is greater around facilities that have been identified as violating an environmental law. In addition, the association between poverty and violations is dependent upon regulatory inspections. While an increase in inspections is associated with an increase in the odds that a violation will be discovered, it is also associated with lower levels of community poverty. We conclude that this pattern of associations between poverty, inspections, and violations is consistent with arguments in the environmental justice and landscape literatures.  相似文献

This study was intended to identify empirically the existence of the home market effect (HME) in Spanish manufacturing industry, a case which shows some incipient evidence in very early stages of development, and an increasing relevance of this phenomenon over time. Our empirical test is carried out with 17 regions between 1965 and 1995, and lends support to the hypothesis of the existence of the HME in five of the nine industries analysed. These results are obtained using a specification in line with the traditional one but new in the sense that it is defined in proportions instead of levels; this approach has conceptual advantages because it is a relative one, like the definition of HME itself.  相似文献

In 2018, Macau will celebrate the 20th anniversary of its return to China. The past few years have witnessed brilliant economic achievements as well as a structural shift toward a gaming-industry dominated economy. Following so many years of rapid growth, it is essential to take stock of both the benefits and costs of gaming industry development. Accordingly, this paper analyzes the evolution of Macau's gaming industry between 1999 and 2016, and evaluates the industry's effects on local economic growth and urban development. As the paper shows, Macau has exhibited many of the symptoms typically associated with booming sectors in small economies, and has witnessed the similar effects widely experienced by western casino cities. However, Macau is also faced with some unique challenges, regarding its geographic location, size constraints, and political factors. These findings illustrate the difficulties that have accompanied Macau's economic achievements, but also call attention to opportunities in the next phase of Macau's development.  相似文献

Amid concerns of how US cities “sprawl”, it is useful to look at the cities of other developed nations, in particular Western Europe which has attained US-type prosperity, but which is reputed to have cities Americans should look to as a model. We examine recent data which suggest that there are substantial development and transportation similarities between the two groups and that the cities of Western Europe are becoming more like those of the United States.  相似文献

This article seeks to elaborate on Forester’s notion of the planner as a “deliberative practitioner”, aiming to add sensitivity to the institutional conditions of planning, focusing especially on Finland. In terms of trust, the concept of deliberative practitioner mostly focuses on interpersonal trust as a planner’s resource in mediating particular interests. Thereby, when applied to the Finnish context, institutional trust may be undermined as a key resource for the Finnish planner’s jurisdiction, justifying his/her proactive role and authority in bringing broader concerns to the planning agenda. This undermining prevents the acknowledgement of important institutional resources that the Finnish planner has in coping with the tensions between communicative ideals and neoliberal realities. A more context-sensitive and institutionally responsive theory of communicative planning is needed to help the planning professionals and other stakeholders conceive the deliberative ideals as supportive for the planners’ institutionally strong agency. Hence, the notion of the “deliberative bureaucrat”. The article seeks to develop an outline for such a theory by drawing upon studies of legal culture, the sociology of professions, deliberative democracy theory and the concept of trust.  相似文献

The Dutch shipbuilding industry has a longstanding tradition in project-based production. Recently, industry actors have acknowledged a serious misfit between interorganizational project practices, defined as behaviors related to collaboration, and interorganizational project demands, defined as environmental conditions. This misfit leads to a weaker competitive position due to higher communication and production costs, and longer production times. However, the causes of this misfit remain unclear. Among project researchers there is a growing awareness that history has a major influence on contemporary practices in interorganizational projects, suggesting that some of the causes of the present-day misfit may be rooted in the past. This paper studies historical developments of interorganizational project practices in Dutch shipbuilding projects, in order to understand to what extent contemporary misfit in project practices is rooted in the past and results from path dependencies and lock-ins. We answer the following research question: How did interorganizational project practices and demands in the Dutch shipbuilding industry develop between 1950 and 2010 and to what extent do these developments help us understand the current misfit between project practices and demands? Our results show that a web of self-reinforcing mechanisms at least partially explains the current misfit in the Dutch shipbuilding industry. This paper answers to the conceptual call by Sydow et al. (2009) and supplements path dependence literature by showing that self-reinforcing mechanisms causing path dependence can be separated analytically, but are intertwined empirically.  相似文献

Using data from the Damage Assessment Reports from the Civil Defence, the current study investigates the relationship between the damage caused by natural disasters and local development at the municipality level in Ceará state, Brazil. The results show that a better urban and water supply infrastructure, a lower population density, and a higher proportion of own revenues relative to total revenues are associated with smaller disaster damage. However, economic development in terms of GDP per capita exhibits a convex relationship with the impact of natural disasters across municipalities, reflecting the potential decreasing returns of preventive investments due to the highly hazardous environment that involves municipalities.  相似文献

The New Urbanism movement arose in part as a response to adverse societal outcomes associated with sprawl. This article seeks to explain the geographic distribution of the “first wave” of New Urbanist developments in the United States according to three sets of factors: common determinants of residential development, environmental advocacy, and local fiscal and regulatory features. We find that early New Urbanist developments in the United States were supported by jurisdictions with large concentrations of groups that have been supportive of New Urbanism (e.g. environmental non-profit organizations and Democratic voters), although these first wave of New Urbanist developments have received criticism that the environmental promise was not fully realized in practice. We argue that the ability to respond to the criticism with remedies in recent New Urbanism movement will be critical to the eventual success of New Urbanism with respect to evolving into a widespread alternative to sprawl.  相似文献

The construction industry immutably produces built environments that directly influence the everyday lives of human beings. Nevertheless, materiality, defined as intransient physical matter socially enacted in the form of artefacts and objects as well as built constructions, is often overlooked and simply regarded as passive and inert matter. In contrast, a growing body of literature recognizes the agency of materiality and examines how materiality and agency are co-produced. When examining a spectacular event like the collapse of the Tjörn Bridge on Sweden’s west coast, it is argued that organizational objects are capable of interpellating various actors, thus enabling informed and adequate action. The concepts of the organizational object and interpellation are thus useful analytical terms when examining construction project organization, helping scholars of the construction industry and practising managers to rethink the role of materiality as something that both acts and is acted upon.  相似文献

In step with economic and political growth, the Korean government is in the process of restoring the main palace, the Gyeongbok Palace, of the Joseon Dynasty (1392–1910), which was destroyed by the Japanese during the colonial era (1910–1945). The ensuing public debate regarding the method and extent of the restoration has brought to the fore the significance such a project carries in Korean society of the twenty‐first century. The restoration of this palace complex has created a number of controversies relating to history and the built environment, urban morphology and national identity. Questions about historical authenticity, both in terms of what has happened to the site since the palace was destroyed and the best means of restoring it; questions about the historical origins of Seoul and the need to restore the palace to make its role in this clear; questions about the methods and materials of restoration, are all matters of debate. There are also cultural and political issues: the role of the built environment in aiding public education; sustaining a sense of national identity; encouraging the development of traditional craftsmen’s techniques for public benefit; bolstering self‐confidence for national progress and expanding the infrastructure for the Korean tourism industry. This paper argues that not only is the physical restoration of the ‘new’ historic buildings and structures important, but also the cultural and social meanings (as outlined above), and that these justify the controversial restoration of the national historic monument.  相似文献

The mild recession experienced in the early part of this decade forced many US electrical contractors to reduce their profit margins as a way to win jobs and survive economically. However, to make up for lower profit margins, contractors turned to ‘better planning’ as a method for improving their efficiency and increasing their profitability. In general, contractors believe that better planning contributes to better project performance, but the evidence has been mostly anecdotal. A study was conducted recently that transformed anecdotal evidence about the impact of pre‐construction planning on performance into quantitative evidence. The research resulted in the development of a model pre‐construction planning process that was based on outstanding projects that were well planned and performed well. The study quantified the relationship between pre‐construction planning activities, project characteristics and performance, and a separate validation study found that those projects that performed a comprehensive planning process similar to the model planning process were more likely to achieve their estimated work hours, profit, budget and completion goals.  相似文献

Social outcomes, in particular intangible social outcomes, are generally difficult to achieve in the construction industry due to the predominantly episodic, fragmented and heavily regulated nature of construction that presupposes a tendency towards mainstream construction processes and design. The Western Australian ‘Percent for Art’ policy is recognized for stimulating social outcomes, by creating richer and more aesthetically pleasing social environments through the incorporation of artwork into public buildings. A case study of four Percent for Art projects highlights the role of the Artwork Selection Committee in incorporating artwork into construction. A total of 20 semi-structured interviews were conducted with committee members and policy officers. Data analysis involved a combination of pattern coding and matrix categorization, and resulted in the identification of the committee’s three key elements of collaborative communication, democratic decision-making and project champions. The findings suggest these key elements foster the interaction, communication and relationships needed to facilitate feedback, enhance relationships, create cross-functional teams and lower project resistance, which are all necessary to overcome constraints to social outcomes in construction. The findings provide greater insight into the mechanisms for achieving social outcomes and a basis for future discussion about the processes for achieving social outcomes in the construction industry.  相似文献

In the Palestinian Territories, housing is thought to be amongst the most difficult problems facing the National Authority (PNA) (Al‐Agha, 1997 Al‐Agha Z (1997) A national outlook for housing in Palestine in: A. B. Zahlan (Ed.) Reconstruction of Palestine, Urban and Rural Development (London, Kegan Paul)  [Google Scholar], p. 3). Increased Israeli settlements, the large size of Palestinian families, the deteriorating economic situation, the lack of national banks operating in the field of housing, the presence of refugee settlements containing over 1.2 million people, the Israeli state's policy of residential demolition and land confiscation have all combined to present a severe obstacle to urban reconstruction in the region. In an attempt to address these issues and to make some progress towards realising the estimated 180 000 housing units required by the Palestinian people, the Palestinian Housing Council (PHC) was established in 1992 (Abd Alhadi, 1994 Abd Alhadi, R (1994) Construction and Housing in the West Bank and (Gaza) Strip (Geneva, United Nations Commission on Trade and Development)  [Google Scholar]; Ziara, 1997 Ziara M (1997) The Palestinian Ministry of Housing. Challenging and opportunities in A. B. Zahlan (ed.) Reconstruction of Palestine, Urban and Rural Development (London, Kegan Paul)  [Google Scholar]). Although it has had some success, the organisation has been plagued by reports of internal dissent and disputes with its beneficiaries. This paper seeks to cast some light on these controversies by focusing on the PHC's role in the Elkarama Housing Project in the Gaza Strip during the period 1993 to 2000.1 Here it must be emphasised that this paper does not claim to provide an analysis of the current situation in Gaza. The authors acknowledge that conditions in Palestine are extremely fluid and have, to a great degree, overtaken the issues considered above. In examining this rapidly‐evolving environment, however, it is valuable to reflect upon recent changes and, while recognising the acute systemic problems that Palestinian administrators face, to offer critical assessments of domestic policy decisions and their outcome. View all notes It will first outline the broader context in which public institutions within the Gaza Strip operate before offering an account of the structure and background of the PHC. It will then consider Elkarama itself and will conclude by summing up the various factors that have determined the project's outcome. Finally, the paper will offer some tentative recommendations for improved housing provisions within the Gaza Strip in the future.  相似文献
