Over the past few years, Microsoft has promoted a project called ‘Shared Source Initiative’, which allows certain customers (e.g., research institutions and independent software vendors) access to its source code on a restricted basis. As part of this initiative, Microsoft introduced some licences that appear to give unrestricted access to source code and closely resemble ‘traditional’ Open Source licences. In July 2007, two of these ‘shared source’ licenses (the Microsoft Community Licence and the Microsoft Permissive Licence) were submitted to the Open Source Initiative (OSI) and subsequently approved by the OSI as certified Open Source licences. Thus Microsoft's Shared Source Initiative and its partial embrace of Open Source appear to be a significant step towards closing the ideological rift between developers of proprietary software and the Free/Open Source software movement, and more than just another attempt to appease consumers and/or critics in terms of software transparency. By analysing the ‘evolution’ of Microsoft's Shared Source licences, this article aims to shed some light on the question what is needed for a ‘predator’ (i.e., proprietary, software developer) such as Microsoft to become ‘prey’ (i.e., be part of the Open Source community). This article concludes that, although Microsoft's efforts are to be lauded, it is highly unlikely that the company will embrace fully the Open Source philosophy in the near future. 相似文献

A key challenge for research and practice is to understand how the ecosystem approach can be rolled out in spatial planning, management and decision-making. Any framework used to apply the ecosystem approach needs to not only be environmentally coherent but also socially meaningful. Drawing on semi-structured interviews and case studies, this paper examines the potential role of one place-based approach, landscape character assessment, as a medium to ensure socio-ecological relevance in operationalising the ecosystem approach. Our findings show that although place-based approaches have value as frameworks for distilling the ecosystem approach into a manageable form, their ecological relevance is a subject of debate. However, the potential relationship between landscape character, function and ecosystem services presented a powerful pathway for operationalising the ecosystem approach. The ecosystem approach may, in turn, complement landscape character assessment by providing a framework for exploring the functional dimension of landscape condition. 相似文献

Assessing landscape preferences: a visual choice experiment in the agricultural region of Märkische Schweiz,Germany 总被引:1,自引:0,他引:1

Natural amenities and the aesthetic value of agricultural landscapes are important territorial assets for improving rural tourism and the quality of the living environment. To identify which characteristics shape the visual quality of a landscape, a stated-preference survey was conducted (N = 200) using photorealistic landscape visualisations of four different landscape attributes (point green elements, linear green elements, crop diversity and presence of livestock). We estimated respondents’ preferences for landscape attributes, examined the extent of agreement among respondents and identified socio-economic factors influencing their responses. Results revealed that point elements had the highest general preference. About 70% of respondents preferred diverse and highly structured landscapes, while about 30% of respondents had opposing preferences. Preferences were also found to be dependent on the individual’s sociocultural background, such as their level of education, gender or age. These results can help to improve the multi-objective targeting of policies by including an aesthetic value perspective. 相似文献

Scholars have expressed concerns about environmental sustainability in low-income housing development in South Africa in terms of the poor households’ relationship with, access to and benefit from natural ecosystems and green spaces. Using a qualitative research approach – discourse-based methods (semi-structured interviews, focus group discussion and transect walks), this paper shows how low-income households in Cosmo City, Johannesburg (South Africa) benefit from green infrastructure at the domestic, neighbourhood and riparian scales. The central lesson from this case is that landscape/urban design, planning and management must recognise and respond to socio-economic and socio-ecological realities and dynamics inherent in the ways low-income households relate with green infrastructure. 相似文献

Considering how poor households relate with natural ecosystems is crucial to achieving environmentally sustainable low-income communities in South Africa and beyond. This paper presents negative experiences associated with residents’ interactions with, perceptions of, and appropriations of natural ecosystems and green spaces in informal settlements in Johannesburg. In-depth interviews with residents in two communities, key informants, and transect walks were used to identify problems associated with domestic gardens and vegetation in riparian and non-riparian open spaces. Inadequate services and infrastructure exacerbates these problems. This work contributes to knowledge regarding undesirable aspects of green infrastructure in the context of urban poverty. Understanding the downsides in human-nature interactions can usefully inform ecologically sound intervention in low-income informal urban areas. 相似文献
