ABSTRACT

Cities can be considered as engines of the knowledge-based economy, because they are the primary sites of knowledge production activities that subsequently shape the rate and direction of technological change and economic growth. Patents provide rich information to analyse the knowledge specialization of specific places, such as technological details and information on inventors and entities involved. The technology codes attributed at the level of individual patent documents can be used to indicate the diversity and scope of the knowledge claims underlying a specific invention. In this study we introduce tools for portfolio analysis in terms of patents that provide insights into the technological specialization of cities. The mapping and analysis of patent portfolios of cities exploits data derived from the Unites States Patent and Trademark Office (USPTO) and dedicated tools (at https://leydesdorff.net/software/patents/). The results allow policy makers and other stakeholders to identify promising areas of further knowledge development, including smart specialization strategies.  相似文献

This article employs gendered livelihoods analysis and participatory methods to examine the politics of development among small-scale rooibos tea farmers in a rural coloured area of southwestern South Africa. Differentiating between sources of conflict and cohesion, I discuss how communities navigated resource scarcity, unstable markets, and shifting relations. While patriarchal dynamics informed livelihoods, with males and elders enjoying greater access than females and young adults, women took advantage of relatively fluid female roles to enter into agriculture and commerce. In contrast, rigid male roles and unattainable expectations of manhood isolated men, engendering destructive behaviors among young men in particular. Communities maintained social cohesion through democratic arrangements, and a politics of identification enabled research participants to relate to differential interests. In addition to providing situated and relational insight into the identitarian aspects of rural development, participatory gendered livelihoods analysis offers a critical means for deconstructing power and decolonizing knowledge.  相似文献

ABSTRACT

Recent research has focused on the impacts of environmental change to tourism. In particular, the perceived costs of climate change have been increasingly studied. However, the relationship between costs and benefits resulting from the changing environmental conditions for the industry has been less examined. This paper identifies the locally observed changes in the natural and socio-economic environments and aims to analyse the financial costs and benefits to tourism businesses in two tourism-dependent communities in northern Finland. The specific focus is on adaptation and adaptive management in a tourist destination scale. Adaption is understood as an investment creating not only implementation costs, but potentially also benefits for tourism operations. Research materials were collected among tourism and tourism-related businesses through 41 semi-structured thematic interviews. Results indicate that the evaluated benefits of environmental change seem to exceed those of costs. This conforms to the on-going discourse of climate change–tourism relations associated with the Arctic region where both awareness and vulnerability to change are considered relatively high but the level of responses, i.e. adaptation, low. These results can help to further identify the most vulnerable sectors in tourism and assist entrepreneurs preparing for environmental and climate change. However, the paper concludes that while global environmental change, with specific adaptive management strategies, may create local short-term direct benefits for the industry, a long-term sustainability of tourism in the Arctic calls for mitigation responses to climate change.  相似文献

旅游投资增长质量对旅游业高速发展和产业转型升级至关重要。利用1999-2014年中国旅游投资省际面板数据,从产出效率与运行过程两方面,系统分析了旅游投资增长质量的时序动态变化与地区差异。结果表明:①考察期内旅游投资增长产出效率提升明显,并处于中高水平。但东中西区域差异明显,中西部旅游投资增长效率低于东部地区,具有一定阶梯性。②旅游投资增长时序波动性较明显,呈现出时冷时热的变化态势,体现出总体稳定性欠佳。东中西区域的稳定性也较差,但自2011年后有所改善。③旅游投资增长协调性不好,表现为旅游投资增长滞后于旅游发展需求。旅游产品(项目)开发与相关基础设施建设,还无法满足快速增长的旅游新需求。这为提升旅游投资质量提供了新的参考与依据。  相似文献

ABSTRACT

Evaluating the rate of deterioration at archaeological sites in the Arctic presents several challenges. In West Greenland, for example, increasing soil temperatures, perennial thaws, coastal erosion, storm surges, changing microbial communities, and pioneer plant species are observed as increasingly detrimental to the survival of organic archaeological deposits found scattered along the country’s littoral zones and extensive inner fjord systems. This article discusses recent efforts by the REMAINS of Greenland project for developing a standardised protocol that defines the archaeological state of preservation, the preservation conditions, and asset value of organic deposits. Special emphasis is given to the degradation of materials such as bone and wood that are historically observed to be well-preserved in Greenland but now currently at risk. The protocol provides a baseline for monitoring future changes and will assist archaeologists in Greenland with a procedure for documenting and predicting areas of increasing vulnerability due to a warming climate.  相似文献

Abstract

This work proposes the term ‘naval elites’ in order to provide a new interpretation of social change in the eighteenth century from a comparative perspective. Naval elites, a social group formed by a part of the naval officer corps and midshipmen, are here defined as a historical instrument, the particular and intriguing features of which may be useful in the revision of some perspectives on social change. In particular, the authors analyse shifting power relationships through the reconsideration of naval patronage and bureaucracy, revisit the process of naval professionalization and the transformation of the concept of merit, and suggest that naval elites embodied new notions of social distinction and exclusiveness.  相似文献

Hunter-gatherers in eastern North America utilized gourds at least 7000 years ago, operating at the early end of a sequence that ended with maize-based agriculture across most of the area. Various subregions differed from each other in timing and degree of participation in premaize crop production. A Midwestern record of native seed plant domestication preceding the adoption of maize is documented, and the significance of this phenomenon is now recognized. Recent archaeobotanical information highlights the amount of geographic variability, limiting the utility of earlier broad-scale interpretations. This paper includes a comparison of sequences in selected subregions: the Midwest/Midsouth, the Southeast, the Lower Mississippi Valley, the Trans-Mississippi South, and the Northeast.  相似文献

Climate change may accelerate the degradation of archaeological sites in the Arctic and lead to a loss of important historical information. This study assesses the current preservation conditions and the processes controlling the physical and chemical stability of the Qajaa kitchen midden in western Greenland. Currently, the site is well protected by low ground temperatures, permafrost and a high water/ice content, keeping the deposits anoxic. Based on 5 years of monitoring data, degradation experiments and model simulation, our results suggest that the combined effects of permafrost thaw, thermal and hydrological erosion and oxygen exposure may lead to substantial loss of archaeological evidence before the end of the 21st century.  相似文献

We analyze morality policy change from the perspective of punctuated equilibrium theory (PET) to test whether reform dynamics in this policy sector follow a distinct pattern. First, we propose a new measurement scheme capturing changes in the intensity of morality policy output. Second, we demonstrate that morality policy change is strongly punctuated. Finally, and most importantly, we show that the degree of policy punctuations varies between different domains of morality policy, but not according to institutional features operating on the country level, supporting existing PET research, which has discovered similar domain‐specific dynamics in changes of public spending. Specifically, punctuations are particularly pronounced in areas of manifest morality policy, that is, policies characterized by strong value conflicts, whereas punctuations are less pronounced for latent morality policies, that is, policies in which other dimensions of conflict are present next to the value dimension. Significant differences in reform dynamics are neither discerned for countries belonging to the religious or the secular world, nor for countries with majoritarian or consensual democracies. The analysis relies on an original dataset capturing legislative changes in five manifest (abortion, euthanasia, prostitution, pornography, and homosexuality), and three latent morality policies (drugs, gambling, and handguns) in 19 European countries (1960–2010).  相似文献

Canada’s religious landscape has changed a great deal over the last forty years and, in most provinces, educational institutions have changed to accommodate this social shift. The articles reviews the divergent ways in which educational regimes have responded to this change and then turns to an examination of the one province in which little has changed regarding religious schools, Ontario. Ontario’s educational structure, which has continued to publicly support only a secular and Roman Catholic separate school systems in one of the most religiously diverse jurisdictions on the planet, is a surprising example of institutional rigidity in the face of societal change. This article highlights the peculiarity of this outcome, attempts to explain this surprising example of institutional continuity, and considers its implications for Canadian secularism more broadly.  相似文献
