中世纪英格兰运输役起源于庄园领主的物资供应需求,随着12、13世纪市场的激增以及运输条件的改善,市场型运输役逐渐普及。运输役一般由农民上层承担,其运输距离、目的地、运输种类等都受习俗制约。运输役衰落的原因主要有直营领地的衰落、运输的专职化以及私下交易的流行。运输役的兴衰与中世纪英格兰市场培育密切相关,是市场已有一定发育但还不太成熟的产物。  相似文献

In November 2012, a researcher, two social workers and five mothers embarked on a participatory action research (PAR) journey with the aim to develop new ideas for interventions for children and young people in street situations of the city of El Alto in Bolivia. In this article, we attend to the topic of personal and social transformation in PAR. We explore how the mothers of young people in street situations perform and negotiate their subjectivities as mothers in their everyday life; how they create (new) subjectivities in exchange and in interaction with each other during the mother project; and how the performance of their (new) subjectivities can bring social change. The mothers in our group shared stories of being silenced by social services in their everyday lives, as their motherhood is declared not good enough or as they are perceived too guilty to claim for help. It was the first time the mothers shared their stories with other mothers of their lives with their children in street situations. By noticing that they all experienced or heard of similar events that their children were subjected to in the streets, the mothers grew confident enough to talk back. Mothers talked back by denouncing injustice and by transforming doubts into questions, providing them with more knowledge. Finally, as the mothers reached out to social services, mothers’ presence, questions and stories confronted aid workers with their own flaws, and their comfortable discourse of blaming families, creating new paths towards social transformation.  相似文献

采用空间统计和空间计量经济学原理和方法对2005-2010年间中国191个城市信息服务业发展的影响因素进行了实证研究。结果表明:城市信息化水平和人力资本对信息服务业的发展具有显著的正向作用;对外开放水平对信息服务业的发展影响不明显;城市间的产业关联对信息服务业发展没有通过显著性水平检验,这表明城市间物质层面的相互交换并没有对信息服务业的发展产生应有的正效应,而相反城市间的信息流动和知识溢出对信息服务业的发展具有显著的促进作用。  相似文献

A range of factors, including consumer concerns about food safety, the growing popularity of rural tourism and policy initiatives to promote endogenous rural development, is converging to promote a relocalization of food production and service provision, especially in those regions marginalized by the globalization of the food supply system. The recent outbreak of foot and mouth disease in the UK has starkly illustrated the fragility of localized systems which depend heavily on consumers travelling to them. Within such a context, the importance of successful marketing strategies has become even more apparent. This paper reports on a questionnaire survey which investigated promotional and marketing strategies among a diverse range of producers and service providers in marginal agricultural areas of the EU. The findings suggest that many producers are situated towards the formal end of a marketing continuum, whereby ability to promote quality products and services (QPS) lies with a range of intermediaries. This raises doubts about the future economic benefits of QPS, should current marketing structures persist. The discussion offers critical reflections on interdisciplinary and international research of this nature, and advocates further theoretical and methodological development in order to explore in more depth many of the aspects raised in this exploratory investigation.  相似文献

Building on research that emphasizes the dependence of services firms on the networks and experiences of individual employees, this paper investigates the urban concentration of information and communication technology services employment in Norway from the perspective of labour market linkages. It finds that urban regions generally provide firms with access to sector-specific expertise. Beyond this, intrinsic region characteristics determine the position of individual firms in national labour markets for expertise: Firms in the dominant university town have strong contact points to academic labour markets, whereas firms in the industrial stronghold of the Western Capital region exploit a broader range of recruitment channels than firms in any of the other urban and non-urban locations. The results illustrate how capability building through recruitment is influenced by local conditions, and imply that the industry will continue to concentrate in the large-city regions where surrounding organizations provide firms with priveliged access to expertise. Implications for research, innovation policy and societal development more generally are drawn.  相似文献

The entrepreneurial ecosystem (EE) literature has attracted much attention, especially in policy circles. However, the concept suffers from a number of shortcomings: (1) it lacks a clear analytical framework that makes explicit what is cause and what is effect in an EE; (2) while being a systemic concept, the EE has not yet fully exploited insights from network theory, and it is not always clear in what way the proposed elements are connected in an EE; (3) it remains a challenge what institutions (and at what spatial scale) impact on the structure and performance of EE; (4) studies have often focused on the EE in single regions or clusters, but lack a comparative and multi-scalar perspective and (5) the EE literature tends to provide a static framework taking a snapshot of EE without considering systematically their evolution over time. For each of these shortcomings, we make a number of suggestions to take up in future research on EE.  相似文献

Costa Rica was the first country in the world to implement a nation-wide payment for environmental services (a.k.a. ‘payment for ecosystem services’), or PES, system in 1996. This research investigates the role of women in PES programs in Costa Rica’s Osa peninsula in response to the current dearth of such gendered research on this topic. Osa, one of the least-developed regions of the country, is still heavily forested and replete with properties under PES contracts which are aimed at forest conservation. Extended, structured interviews of 80 landowners in Osa (40 women and 40 men) culled both quantitative and qualitative information about PES participation, environmental perceptions, and both economic and conservation goals. Salient results were, first, that women see current levels of PES funding as more helpful and useful than do men. Second, women much more often perceive themselves as the sole entity responsible for protecting the environment. Third, women more commonly than men listed ‘helping the environment and animals’ as a personal benefit of their PES participation, while men more commonly focused on financial rewards. Last, according to the study herein, women in PES households currently display less decision-making power than those in non-PES households. This dynamic is analyzed through the lens of patriarchal hierarchies as well as women’s mitigation of those hierarchies through the deployment of ideology and agency. Based on these general findings, the researcher recommends that FONAFIFO, the government agency in charge of PES payments, take specific steps to increase PES funding to female-headed households.  相似文献

During the last decade, we have witnessed an increased interest in Ecosystem Services (ES), including the so-called ‘cultural ecosystem services’ and its subcategory of ‘cultural heritage’. In this article, a review of academic literature of ES and cultural heritage is carried out. ES has primarily been developed by scholars from the ecological and economic disciplines, and in this article, we discuss how this impacts the way in which cultural heritage is used and conceptualised in ES literature. Based on the conceptual review, we initiate a discussion of what the implications for cultural heritage management could be if the heritage sector adopts the rationales in the ES framework.  相似文献

Invasive vegetation species can lead to major changes in the geomorphology of coastal systems. Within temperate estuaries in the southern hemisphere, especially Australia and New Zealand, the cordgrass Spartina spp. has become established. These species are highly invasive, and their prolific growth leads to the development of supratidal environments in formerly intertidal and subtidal environments. Here, we quantified the impact of Spartina invasion on the geomorphology and sequestration capacity of carbon in the sediments of Anderson Inlet, Victoria, Australia. Spartina was first introduced to the area in the 1930s to aid in land reclamation and control coastal erosion associated with coastal development. We found that Spartina now dominates the intertidal areas of the Inlet and promotes accretion (18 mm/year) causing the formation of over 108 ha of supratidal islands over the past 100 years. These newly formed islands are calculated to potentially contain over 5.5 million tonnes of CO2 equivalent carbon. Future management of the inlet and other Spartina‐dominated environments within Australian presents a dilemma for resource managers; on the one hand, Spartina is highly invasive and can outcompete native tidal marshes, thereby warranting its eradication, but on the other hand it is likely more resilient to rising sea levels and has the potential for carbon sequestration. Whether or not the potential advantages outweigh the significant habitat change that is anticipated, any management strategies will likely require additional research into costs and benefits of all ecosystem services provided by Spartina including in relation to nutrient cycling, shoreline stabilisation, and biodiversity as well as in response to the longevity of carbon found within the sediments.  相似文献

In Australia, e-government is continuously re-defining service boundaries. While this may be good in the case of transactional interactions, for example the online submission of tax returns, it is less clear that interpersonal services, such as working closely with the long-term unemployed, are best delivered digitally. We consider the impact of social services digitisation on vulnerable communities drawing on an analysis of remote Aboriginal communities. Digital uptake affords great opportunities, but it also carries risks. Some communities have no digital infrastructure and in certain cases traditional face-to-face services have been curtailed, leaving those not online with reduced assistance. We find that concerns about the ‘digital divide’ are well founded. Problems generated by e-government flow across boundaries and appear left to the third sector to resolve with the state playing an even more diminished role in the lives of disadvantaged citizens.  相似文献
