Spatio-temporal patterns of intentional fires,social stress and socio-economic determinants: A case study of Malmö, Sweden

Since the end of the 1990s, the number of fires has increased dramatically in Malmö, a city in the southernmost part of Sweden. Between 1998 and 2009, the increase was 215%, and a large number of the fires were intentional. The aim of this paper is to deepen our understanding of the underlying causes of the spatial and spatio-temporal distribution of intentional fires in Malmö, and to analyse how different living conditions in Malmö sub-areas may determine the frequency of intentional fires. This paper׳s main contributions to the field is to operationalize theories of social stress into measurable variables and an index of living conditions (ILC), and to statistically and spatially analyse the underlying relationship between living conditions and intentional fires. One key conclusion is that the spatio-temporal patterns of intentional fires can be determined by different living conditions and different levels of exposure to socio-economic stressors. Another important finding is to emphasize the importance of analysing specific and local patterns of fire incidents and living conditions in order to utilize them in locally-adapted fire safety policy formulations and in implementing preventative measures.     

EXEHDA-HM: A compositional approach to explore contextual information on hybrid models

The current proposals of hybrid context modeling bring new challenges, an important one is how applications can access and process data stored on these models. Thinking about that, this paper proposes a solution to deal with this challenge through a compositional approach that explores the context information on hybrid models, called EXEHDA-HM. The proposed approach stands out by the design of a repository that supports three database models and by the compositional processing strategy based on rules. In our proposal, the applications can combine data stored on different bases in a single rule, which could enhance the identification of contextual situations. For the evaluation we designed and implemented some case studies on information security area, exploring the hybrid repository composed of relational, non-relational, and triple storage models. Our results demonstrate that was possible to identify richer situations with the data composition across more than one model and there are situations that can only be found through this composition.     

城市雕塑空间的大众认同价值特征

在日常生活美学的影响下，城市景 观体现出更加生活化的审美情趣，“如画景 观”变成了“如话景观”，大众在公共活动 中通过感官参与和文化参与去对话自然、 社会、和个人经历，城市雕塑空间正承担了 这样的精神功能。基于上海静安雕塑公园 进行了雕塑空间的大众认同价值探究，开 创性地基于用户体验思维——同理心地图 （E mpt hy m ap）研究认同活动，得出感官 参与、文化参与、均衡参与三种价值模式， 并强调文化参与在认同中的重要价值。     

传承与分离 ——以建筑学专业两个毕业设计为例

文脉对于建筑创作有着深远的影 响。对于文脉的不同应答将会使建筑师形 成不同的设计思路与应对策略。建筑师不 应该简单地、形而上地顺从所处的文化与自 然环境，而应该深入研究和把握文脉，突破 “形”的束缚。本文通过剖析笔者所指导的 两个优秀毕业设计，阐述传承与分离均是对 于文脉不同的响应方式，都可以实现建筑与 环境的和谐共生。

Effect of the sequence context of the AUG initiation codon on the rate of translation in dicotyledonous and monocotyledonous plant cells

The sequence context around the AUG initiation codon strongly contributes to the translation initiation step in mammalian and plant cells. Here, we investigated the effect of the three nucleotides immediately upstream of the initiating AUG (positions − 3 to − 1) on the translation efficiency of a reporter gene, β-glucuronidase, in dicotyledonous and monocotyledonous plant cells.

Poly(ethylene glycol) as a ‘green solvent’ for the RAFT polymerization of methyl methacrylate

We demonstrate the use of a range of poly(ethylene glycol)s (PEGs) to control the polymerization of methyl methacrylate (MMA) using reversible addition-fragmentation chain transfer (RAFT) polymerization. The use of PEG as the solvent (M_n = 4600 g mol⁻¹) resulted in an increase in the rate of the reaction over that of other solvents by a factor of 5 at 60 °C, allowing MMA to be polymerized to high conversions with a DP of 100 much more rapidly than in standard solvents, while maintaining control over the molecular weight with polydispersities as low as 1.05. Interestingly, whilst the same rate increase is seen when polymerizing to a DP of 500, PEG appears to limit the achievable molecular weight to differing degrees depending on its chain length. Advantages of using PEG include its very low toxicity and other environmentally friendly aspects of its nature that allow it to be classed as a ‘green’ solvent.
