Church-based social capital, networks and geographical scale: Katrina evacuation, relocation, and recovery in a New Orleans Vietnamese American community

This research examines the role of social capital and networks to explain the evacuation, relocation, and recovery experiences of a Vietnamese American community in New Orleans, Louisiana in the aftermath of Hurricane Katrina. As the single largest community institution, the parish church’s complex bonding and bridging social capital and networks proved particularly critical in part because of its historically based ontological security. The process of evacuation, but especially relocation and recovery, was dependent on deploying co-ethnic social capital and networks at a variety of geographical scales. Beyond the local or community scale, extra-local, regional, and national scales of social capital and networks reproduced a spatially redefined Vietnamese American community. Part of the recovery process included constructing discursive place-based collective-action frames to successfully contest a nearby landfill that in turn engendered social capital and networks crossing ethnic boundaries to include the extra-local African American community. Engaging social capital and networks beyond the local geographical scale cultivated a Vietnamese American community with an emergent post-Katrina cultural and political identity.     

VIETNAMESE AMERICAN PLACE MAKING IN NORTHERN VIRGINIA*

ABSTRACT. Vietnamese Americans have made places for themselves in Northern Virginia by reconfiguring the geography of the suburban places they inherited, including former high-order central-place nodes. Vietnamese American residences, churches, cemetery plots, and other distinctive ethnic markers are by and large dispersed and rarely noticeable. Their retail districts, however, serve them in multiple material and symbolic ways, not unlike suburban Chinatowns.     

Minority women’s microenterprises in rural areas of the United States of America: African American,Hispanic American and Native American case studies

Women in many rural areas of the US often engage in small-scale businesses as one of several avenues for contributing to household incomes. In those geographical areas that contain a significant minority population, many of the women's businesses display the cultural diversity of the regions in which they live. Likewise, women's roles as economic providers as well as wives and mothers are reflected in the manner in which they operate their businesses. Candida Brush suggests that women's strategies for operating their businesses are highly integrative because women's business decisions are intertwined with familial responsibilities, household economic demands and desires to contribute to their communities. Hispanic and Native American women in the Four Corners region of southwestern US and African American women in central Virginia participated in interviews in which they responded to numerous short answer and open-ended questions about their businesses and decision-making strategies. From these interviews an image emerges of rural minority business women who are operating their businesses at the nexus of family obligations, economic necessities, cultural ties and with a commitment for serving their communities. This revised version was published online in July 2006 with corrections to the Cover Date.     

A comparative study of the design spectra defined by Eurocode 8, UBC, IBC and Turkish Earthquake Code on R/C sample buildings

Earthquake codes have been revised and updated depending on the improvements in the representation of ground motions, soils and structures. These revisions have been more frequently seen in recent years. One of the key changes in earthquake codes has been performed on the design spectra. In this paper, the design spectra recommended by Turkish Earthquake Code and three other well known codes (Uniform Building Code, Eurocode 8, and International Building Code) are considered for comparison. The main purpose of this study is to investigate the differences caused by the use of different codes in the dynamic analysis and seismic verification of given types of buildings located at code defined different sites. The differences in expressions and some important points for elastic and inelastic spectra defined by the codes are briefly illustrated in tables and figures. Periods, base shears, lateral displacements and interstory drifts for the analyzed buildings located at code defined ground type are comparatively presented.     

Working towards conceptual consistency in discussing “diaspora” and “diaspora strategies”: Ethnicity and affinity in the case of Japan

The terms “diaspora” and “diaspora strategies” are both used in inconsistent, and often, conflicting ways. Who encompasses “the diaspora” and what are “diaspora strategies”? What roles do ethnicity and affinity play in conceptualizing relationships between diasporas and homeland governments? This paper extrapolates from programs and organizations that link overseas coethnic and former resident non-coethnic populations to Japan to offer clarity and consistency in usage by bringing together concepts not typically put in conversation with each other and introducing new terms that conceptualize more specific aspects of who we are referring to as “diaspora” and what we are referring to as “diaspora strategies”. Conceptualizations of diaspora often gloss over internal differences, including whether or not people deemed members of a diaspora actually demonstrate a homeland orientation. Focusing on the difference between ethnicity-based and affinity-based definitions of diaspora, I distinguish between three types of diaspora strategies: “diaspora-connecting”, “diaspora-cultivating”, and “diaspora-creating strategies”. Finally, as a way to discuss the potential contributions of both overseas coethnic and non-coethnic populations to a given nation, I conclude by considering Joseph Nye’s notion of “soft power” in relation to diaspora strategies. By engaging these concepts together, the paper highlights the tensions between considering ethnicity and affinity as factors for deciding who to target for diaspora strategies, and demonstrates how diaspora strategies can also target non-coethnics.     

Moment magnitudes of two large Turkish earthquakes on February 6, 2023 from long-period coda

Two large earthquakes (an earthquake doublet) occurred in south-central Turkey on February 6, 2023, causing massive damages and casualties. The magnitudes and the relative sizes of the two mainshocks are essential information for scientific research and public awareness. There are obvious discrepancies among the results that have been reported so far, which may be revised and updated later. Here we applied a novel and reliable long-period coda moment magnitude method to the two large earthquakes. The moment magnitudes (with one standard error) are 7.95±0.013 and 7.86±0.012, respectively, which are larger than all the previous reports. The first mainshock, which matches the largest recorded earthquakes in the Turkish history, is slightly larger than the second one by 0.11±0.035 in magnitude or by 0.04 to 0.18 at 95% confidence level.

Abstract

The recent publication of an expansive national dataset, the Integrated Public Use Microdata Sample, allows for new analyses of the historical geography and settlement of various immigrant and ethnic groups in the United States. The present research explores the growth, development, and geographic dispersion of the ethnic Mexican population, and outlines some of the demographic and social characteristics within significant clusters of this population in the United States across the first half of the twentieth century. The analysis does not attempt to overturn other geographies and ethnographies in Mexican American history, but through its ability to elucidate broad, national patterns it is able to create a more dynamic view of settlement, demonstrating the role of immigrants and of women immigrants in particular. Results indicate that place matters: the geographical context of arrival and settlement were key factors in differentiating communities and the lives of those who lived in them.     

A comparison of the contribution of zooplankton and nekton taxa to the near-surface acoustic structure of three Turkish seas

The bioacoustics of upper waters of the Black Sea, the Sea of Marmara, and the Mediterranean Sea were studied in October 1999 with an echosounder with 120 and 200 kHz dual‐beam transducers. Net tows were taken to ground‐truth the acoustic volume backscattering. A forward solution was applied to determine significant scatterers of the three seas with regard to detection limits of the frequencies and background noise measured in each sea. The noise was 4 dB higher in the Sea of Marmara than in the other two seas. 200 kHz data showed significant correlation between measured and calculated volume backscattering strength, and density (biomass and abundance) of the taxa. Large‐sized copepods and chaetognaths in the Black Sea, Aurelia, Beroe, chaetognaths and large‐sized and abundant appendicularians in the Sea of Marmara, and fish larvae in the Mediterranean Sea contributed most to the volume backscattering.     

Chicago: Patterns of the Metropolis

Abstract

Thematic maps reveal the geography of any area. A series of such maps introduces the growth, landforms, railroad lines, African-American population, population density, and population change in Chicago. Many of these patterns have been laid down in past times, but they also influence present and future trends.
