The study shows the relation between urban green and (urban) stress within the urban district Bonn, Germany. How do urban ecosystem services influence the subjective well-being? A triangulation of methods (site’s inspections, online survey) was applied to collect data on the availability and state of urban green spaces regarding the urban district of Bonn and by whom, why and how often they are visited. Of special interest could be the ecological state of the green space. The ecological state of green spaces in Bonn was assessed and connected to the results of the online survey. Thus, health effective potentials of urban green can be given. Main advantages were proved by an excellent network of green infrastructure as well as big green spaces or rather open catchment areas.  相似文献

With several instruments the Rhineland-Palatinate’s city Andernach implements a sustainable modular system of communal green planning. Considering ecological, economic and social issues the integration of urban agriculture in the urban green space is fundamental. The aim is to form public green space more creative and to support urban biodiversity.  相似文献

The Ruhr area has advanced to the largest university region in Germany – often unnoticed within and outside. At the same time scientific institutions have become a major economic factor. Because of the higher and extra-university research institutions about 2.5 billion euros are effective as a demand potential in the region. 1.7 billion euros of this amount are directly associated with investments and operating expenditures of the scientific institutions as well as consumptions of employees and students. Additional 770 million euros result in revenues of many branches such as trade, housing, gastronomy sector, handcraft industry etc. It should not be underestimated that higher and extra-university research institutions generate with their research activities particular funding from the European Union or the rest of Germany for benefit of the region. Each euro spent by the state government for basic funding creates 39 cents third-party funding. These regional-economic effects result in noticeable employment impacts within the region. Around 25,000 people are directly employed in higher and extra-university research institutes or student unions (Studierendenwerke), about 22,000 jobs in other economic sectors are ensured or created by the induced demand. Science has thus become an important economic factor and represents an essential counterbalance to employment decline in shrinking industries of the region. The specific inclusion of science in a regional development strategy and targeted relining with appropriate measures to strengthen the science creates therefore an effective starting point for the design of structural change.  相似文献

The German school system is socially highly unequal, as educational research criticized for a long time. While in some schools socially privileged pupils are the majority, other schools are composed by mostly poor pupils. The combination of socio-geographic and educational geographic considerations leads to a social school index, which clearly shows how strong schools are socially privileged or disadvantaged. The paper presents a practical example of building a social school index for cities and compares the results. The residence-based density index on grid data from German Social Code (book 2) is preferred because it is unproblematic in terms of data protection law and can be extended at the level of 100 × 100?m grids. Calculating detailed and differentiated social school indices with school enrollment data leads to very good results, but is much more work.  相似文献

A total of 74 glass beads, included as grave goods in 15th–17th century CE jar burials from Cambodia's Cardamom Mountains, were analysed using laser ablation – inductively coupled plasma – mass spectrometry (LA–ICP–MS). Several glass types were identified, including two subtypes of high‐alumina mineral soda glass, and lead–potash glass. The final glass type represents a newly discovered and previously unidentified type of high‐alumina soda glass, with high magnesia (m‐Na–Al Mg>). This study represents the first glass data from the mid‐second millennium CE from Cambodia and sheds light on the multiple long‐distance maritime exchange networks in which the upland people buried in the jars were participating.  相似文献

Recognizing the critique of sexual essentialism in the Women, Peace and Security (WPS) agenda, this article moves beyond this familiar narrative to address the narrowness of conflict frames that have to date been engaged by the WPS agenda. The events of 11 September 2001 brought new urgency and vibrancy to state action in the realm of counterterrorism. This momentum was illustrated both by the response of national legal systems and by more concerted efforts to achieve multilateral and multilevel counterterrorism cooperation on the international level. Notably, terrorism and counterterrorism have long been of only marginal interest to mainstream feminist legal theorists. Until recently concerted analytical feminist scrutiny has been missing in the assessment of terrorism, radicalism and counterterrorism discourses. This article addresses the lack of attention to terrorism, counterterrorism and countering violent extremism (CVE) initiatives in the WPS mandate and its consequences for mainstreaming gender interests in foundational aspects of peace and security practice. Recent normative augmentations including UNSCR 2242 and the amplified mandate of the Counter‐Terrorism Committee to include gender considerations are assessed. The article argues that these moves to include gender come late, and on the terms set by security‐minded states. The late attention to gender in counterterrorism leaves little capacity to produce an inclusive and reimagined feminist agenda addressing the causes conducive to the production of terrorism and the costs to women of counterterrorism strategies. This pessimistic assessment warns of the pitfalls of exclusion and inclusion in the new security regimes that have been fashioned post 9/11 by states.  相似文献

Why does any member of Congress choose to be loyal to one's party? The conventional wisdom is that party loyalty stems from constituent expectations, electoral concerns, or a lawmaker's ideological beliefs. However, this neglects two other, less-instrumental reasons for sticking with a political party: partisan identity and personal connections with party leaders. I test these alternative theories as well as conventional ones on a set of key moments in the 113th Congress (2013–2014) when rebellion against House Republican leadership by the rank-and-file was especially noteworthy. The results provide some support for both the party identity and personal connection hypotheses. They also indicate that although constituency characteristics help predict the likelihood of dissent from GOP leaders, there is little evidence for the electoral hypothesis, while cross-cutting ideological preferences as well as preferences along the traditional left-right spectrum prove statistically significant. In short, evidence reveals both personal and instrumental roots of party loyalty in Congress.  相似文献

This article evaluates the current state of paleoethnobotany since Hastorf’s 1999 review published in this journal. We discuss advances in methods, ancient subsistence reconstructions, the origins and intensification of agriculture, and how plants inform on issues of political economy and identity. Significant methodological developments in the extraction, identification, and analysis of starch grains and phytoliths have led to advancements in our knowledge of early plant domestication and the transition to food production. Paleoethnobotanists increasingly are using more complex quantitative techniques to characterize their data, which have resulted in more nuanced interpretations of plants that fall within the purview of social archaeology and allow us to address issues related to gender, identity, and ritual practice.  相似文献
