--While a large fraction of application code is devoted to graphical user interface (GUI) functions, support for reuse in this domain has largely been confined to the creation of GUI toolkits ("widgets"). We present a novel architectural style directed at supporting larger grain reuse and flexible system composition. Moreover, the style supports design of distributed, concurrent applications. Asynchronous notification messages and asynchronous request messages are the sole basis for inter-component communication. A key aspect of the style is that components are not built with any dependencies on what typically would be considered lower-level components, such as user interface toolkits. Indeed, all components are oblivious to the existence of any components to which notification messages are sent. While our focus has been on applications involving graphical user interfaces, the style has the potential for broader applicability. Several trial applications using the style are described.

Social media and other online communication tools are a subject of great interest in mass emergency response. Members of the public are turning to these solutions to seek and offer emergency information. Emergency responders are working to determine what social media policies should be in terms of their "public information" functions. We report on the online communications from all the coastal fire and police departments within a 100 mile radius of Hurricane Sandy's US landfall. Across four types of online communication media, we collected data from 840 fire and police departments. Findings indicate that few departments used these online channels in their Sandy response efforts, and that communications differed between fire and police departments and across media type. However, among the highly engaged departments, there is evidence that they bend and adapt policies about what constitutes appropriate public communication in the face of emergency demands; therefore, we propose that flexibility is important in considering future emergency online communication policy. We conclude with design recommendations for making online communication media more "listenable" for both emergency managers and members of the public.

Focus on behaviors, not on fetishizing social media tools

Racial categories are cultural ascriptions whose construction and transmission cannot be taken for granted. I focus here on the process by which racial categories are themselves constructed; in particular, I examine the presence of place and the role of state in the making of one such category, the "Chinese," in a British settler society from the 1880s to the 1920s. I argue that "Chinatown," like race, is an idea that belongs to the "white" European cultural tradition. The significance of government is that it has granted legitimacy to the ideas of Chinese and Chinatown, inscribing social definitions of identity and place in institutional practice and space. Indeed Chinatown has been a critical nexus through which the race definition process was structured. I examine this process in Vancouver, British Columbia, where the municipal authorities of the late nineteenth and early twentieth centuries sanctioned the intellectual milieu of race. They did this, I argue, as part of the historical exercise of white European cultural domination. In short, I wish to uncover the dynamic between place, racial discourse, power, and institutional practice by way of contributing to the recent rediscovery of place in human geography.

Third molar (M3) development determined from dental radiographs in American blacks (African Americans; n=637) aged 14-24 years was contrasted against American whites (n=563) from a previous study using the method of Demirjian et al. Differences were assessed using descriptive statistics and the parametric proportional hazards model. For each developmental stage, the probability of an individual being at least 18 years old was evaluated. As in other M3 studies, there were highly significant modal differences, but the age ranges at each stage overlapped considerably. Black-white differences were highly significant with developmental stages occurring in blacks a year or so earlier. Gender differences also varied significantly, both with increasing age and between races. The empirical likelihood that an African American male with fully developed M3's is at least 18 years old is 93% and that for African American female is 84%. Corresponding risks for whites are 90% and 93%.

Against a backdrop of growing interest in animal geographies and the genetic engineering of species, this article critically examines the process of animal domestication. To date, the social selection and breeding of animals have received little deconstructive effort from human scientists. The article begins by reviewing earlier schools of geographic thought on domestication, including the work of Carl Sauer, for whom domestication was a transhistorical process of evolution's unfolding. In working away from that perspective, I historicize animal domestication within a narrative politics of ideas about human uniqueness, savagery and civilization through which the process was conceived and conducted from at least classical times. The article thus develops a cultural critique of technologies that have been fundamental to the transformation of landscapes. Integral to the story are concepts of ‘domus’ and ‘agrios’, the ‘bringing in’ of ‘the wild’, and associated notions of containment, fixity, settling and improvement. These ideas, I argue, became threaded into the relations of not only humans and certain animals but also raced and gendered relations in European-derived societies. The article concludes with appeals to the imagining of more animal-inclusive models of social relations; the relaxation of rigid oppositions of civility and wildness; and a ‘human’ Self more conversant with its own wild side, dedomesticated and unbound.
