Assessing vulnerability to earthquake hazards through spatial multicriteria analysis of urban areas

Abstract: Assessing urban vulnerability to natural hazards such as earthquakes can be regarded as an ill-structured problem (i.e. a problem for which there is no unique, identifiable, objectively optimal solution). A review of the literature indicates a number of contrasting definitions of what vulnerability means, as well as numerous conflicting perspectives on what should or should not be included within the broad assessment of vulnerability in cities. This paper reports on the findings from a project in which a GIS methodology has been developed to assess urban vulnerability through a spatial analytical procedure. First, we highlight the deficiencies of current GIS approaches to urban vulnerability analysis and discuss the ill-structured nature of the vulnerability problem. We then propose a working definition for vulnerability assessment in which vulnerability is thought of as a spatial decision problem under the conditions of uncertainty. Next, we present a methodology to incorporate this definition into a GIS...

Trends in U.S. Adolescents’ media use, 1976–2016: The rise of digital media, the decline of TV, and the (near) demise of print.

Abstract: Studies have produced conflicting results about whether digital media (the Internet, texting, social media, and gaming) displace or complement use of older legacy media (print media such as books, magazines, and newspapers; TV; and movies). Here, we examine generational/time period trends in media use in nationally representative samples of 8th, 10th, and 12th graders in the United States, 1976–2016 (N 1,021,209; 51% female). Digital media use has increased considerably, with the average 12th grader in 2016 spending more than twice as much time online as in 2006, and with time online, texting, and on social media totaling to about 6 hr a day by 2016. Whereas only half of 12th graders visited social media sites almost every day in 2008, 82% did by 2016. At the same time, iGen adolescents in the 2010s spent significantly less time on print media, TV, or movies compared with adolescents in previous decades. The percentage of 12th graders who read a book or a magazine every day declined from 60% in the late 1970s to 16% by 2016, and 8th graders spent almost an hour less time watching TV in 2016 compared with the early 1990s. Trends were fairly uniform across gender, race/ethnicity, and socioeconomic status. The rapid adoption of digital media since the 2000s has displaced the consumption of legacy media.

Thermodynamic length and dissipated availability

Abstract: New expressions for the availability dissipated in a finite-time endoreversible process are found by use of Weinhold's metric on equilibrium states of a thermodynamic system. In particular, the dissipated availability is given by the square of the length of the corresponding curve, times a mean relaxation time, divided by the total time of the process. The results extend to local thermodynamic equilibrium if instead of length one uses distance (length of the shortest curve) between initial and final states.

Peasant and Nation: The Making of Postcolonial Mexico and Peru

Abstract: Peasant and Nation offers a major new statement on the making of national politics. Comparing the popular political cultures and discourses of postcolonial Mexico and Peru, Florencia Mallon provides a groundbreaking analysis of their effect on the evolution of these nation states. As political history from a variety of subaltern perspectives, the book takes seriously the history of peasant thought and action and the complexity of community politics. It reveals the hierarchy and the heroism, the solidarity and the surveillance, the exploitation and the reciprocity, that coexist in popular political struggle. With this book Mallon not only forges a new path for Latin American history but challenges the very concept of nationalism. Placing it squarely within the struggles for power between colonized and colonizing peoples, she argues that nationalism must be seen not as an integrated ideology that puts the interest of the nation above all other loyalties, but as a project for collective identity over which many political groups and coalitions have struggled. Ambitious and bold, Peasant and Nation both draws on monumental archival research in two countries and enters into spirited dialogue with the literatures of post-colonial studies, gender studies, and peasant studies.
