Seasonal variation of high-molecular-weight compounds in the water-soluble fraction of organic urban aerosols

Aerosol samples were collected in Zurich, Switzerland, at an urban background site and were analyzed with size exclusion chromatography (SEC) and laser/desorption ionization mass spectrometry (LDI-MS) for water-soluble organic compounds with high molecular weight. Daily samples were collected during two campaigns in winter and summer, for 1 month each. The concentration of high-molecular-weight compounds (humic-like substances (HULIS)) was between 0.4 and 4 μg/m3 in winter and summer. The most intense signals in the LDI-MS mass spectra were measured between m/z150 and 500, comparing well with the mode of the two main high mass peaks determined with SEC corresponding to masses between 200 and 600 Da. For the maximum molecular weight, however, different results were obtained by the two techniques: whereas a maximum molecular weight between 1300 and 3300 Da was found with SEC, hardly any peaks above m/z700 were measured with LDI-MS. During summer the maximum molecular weight of HULIS (determined with SEC) correlates positively with several parameters such as ozone and increased temperature indicative of enhanced atmospheric photo-oxidation. The HULIS concentration also correlates positively with the oxalic acid concentration in the particles. This suggests that HULIS are generated by secondary processes in summer. The lack of such correlations during winter suggests that other sources and processes might be important during colder seasons.

Sherman Alexie’s "The Toughest Indian in the World": Amalgamating the Oral and the Written Traditions

This article argues that The Toughest Indian in the World (2000) by Native-American author Sherman Alexie combines elements of his tribal (oral) tradition with others coming from the Western (literary) short-story form. Like other Native writers — such as Momaday, Silko or Vizenor — , Alexie is seen to bring into his short fiction characteristics of his people’s oral storytelling that make it much more dialogical and participatory. Among the author’s narrative techniques reminiscent of the oral tradition, aggregative repetitions of patterned thoughts and strategically-placed indeterminacies play a major role in encouraging his readers to engage in intellectual and emotional exchanges with the stories. Assisted by the ideas of theorists such as Ong (1988), Evers and Toelken (2001), and Teuton (2008), this article shows how Alexie’s short fiction is enriched and revitalized by the incorporation of oral elements. The essay also claims that new methods of analysis and assessment may be needed for this type of bicultural artistic forms. Despite the differences between the two modes of communication, Alexie succeeds in blending features and techniques from both traditions, thus creating a new hybrid short-story form that suitably conveys the trying experiences faced by his characters.

Intra urban air temperature distributions in historic urban center

The study investigates the urban heat island effect in Malaysian historic town Malacca through seven mobile traverses, as carried out on 10 December 2011. It aims to identify the intra-urban air temperature differences between heritage core zone, new development area and outskirts of the city. Air temperature variations were also analyzed across three different zones; namely the outskirts, the heritage site and the city center district. Heat index values were then calculated based on air temperature and relative humidity to gauge the level of outdoor thermal comfort within the study area. Based on the indications, one may conclude that the heritage place’s core zone is currently threatened by escalating temperatures and that its current temperature range falls within the “caution” and “extreme caution” categories. Furthermore, no significant difference was observed between the peak temperatures of the old city quarters and newer areas; despite the disparities in their urban forms. Therefore, it is hoped that the study, with its implications, will be able to influence future environmental consideration in heritage city of Melaka.

Belonging and the uses of difference: young people in Australian urban multiculture

This paper examines how young people of migrant background in Australia make meaning of cultural, ethnic and racial difference to work out belonging in times of super-diversity. It asks what functions difference still has for a generation growing up within conditions of proliferating diversity that demand and accommodate competing constructions of cultural identities. It suggests that young people's narratives about difference depend on the space of belonging, and explores how young people use difference differently depending on whether they are articulating membership in the local community, the nation or youth culture.

An experimental study of the effect of intergroup contact on attitudes in urban China

A large body of literature attests to the growing social divide between urban residents and rural–urban migrants in China’s cities. This study uses a randomised experiment to test the effect ofintergroup contact on attitudes between a group of urban adolescents and a group of rural–urbanmigrant adolescents. Results showed that intergroup contact in the form of a fun and cooperativepuzzle task significantly reduced negative attitudes toward the other group. Implications fordesegregated schooling and their broader societal implications in China are discussed.

Urban sustainability in the Arabian Gulf: air conditioning and its alternatives

This paper examines shifting approaches to urban sustainability in the Arabian Gulf by focusing on the issue of air conditioning and thermal comfort. It considers the recent foregrounding of tradition and heritage within the arena of mega-project development in Qatar, using the Msheireb Downtown Doha Project as an example of a wider regional trend around urban sustainability. Through its focus on air conditioning, the paper draws on Appadurai’s recent critique of design singularity to examine built environment sustainability in relation to the indoor comfort norms and practices, for both bodies and objects, which are now well established across the Gulf region.

Learning wellness : how ageing Australians experience health information literacy

Given identified synergies between information use and health status greater understanding is needed about how people use information to learn about their health. This article presents the findings of preliminary research into health information literacy which sought to explore how this is phenomenon is experienced among ageing Australians. Analysis of data from semi-structured interviews has revealed six different ways ageing Australians experience using information to learn about their health within one aspect of community life. Health information literacy is a new terrain for information literacy research endeavours and one which warrants further attention by the profession to foster and promote within the community.

Portrayal of librarians in Australian creative writing

An exploration is made of the ways in which librarians have been depicted in Australian creative writing. Reference is made to characters in novels, short stories, drama and poetry. With respect to novels, there is some consideration of characterisation and its relationship to plot.
