    Given recent demographic shifts and changes in the racial landscape of many urban areas, what kind of inter-group relations have emerged and what are the prospects for cross-racial coalitions to contest racial hierarchies and structures of racial inequality in the USA? Drawing on qualitative data, I examine the efforts of an environmental justice organization, defined as a `border space', to build solidarity and forge alliances between second-generation Laotians and other communities of color in the San Francisco Bay Area. I argue that the possibilities and limits to engendering cross-racial solidarity are also shaped by Laotians' status as new immigrants and as Asian Pacific Americans, as well as by everyday encounters and interactions between racial groups. Racializing processes in the US engender complex inter-minority relations that are marked by cooperation or conflict. In such a context, cross-racial alliances are based on political commitments and shared interests that are contingent and situationally specific

    Refugee Women’s Volunteering as Resistance Practices to Micro‐Aggressions and Social Exclusion in the UK

    In an increasingly hostile environment for refugees in the UK and the “everyday bordering” that creates exclusionary effects for refugees and migrants, this article examines how refugee women of diverse backgrounds enact resistance practices through volunteering to challenge everyday microaggressions and social exclusion. We draw on in‐depth qualitative research with members of a support group for refugee women established by a local charity in England. We find that the support group not only allows the refugee women to foster a strong sense of solidarity in the face of everyday microaggressions; it also facilitates the women’s volunteering activities in the local community. Applying the concept of “differentiated embedding,” we argue that such activities enable these women to build wider social connections and skills for future employment and, crucially, develop emotional and linguistic resources to critique dominant exclusionary discourses and policies towards refugees through the idea of “contribution” and “giving back.” In so doing, we contribute to renewed interest in the concept of integration to highlight the agency of refugee women in creating differentiated embedding in a hostile environment

    Small airway hyperresponsiveness in COPD: relationship between structure and function in lung slices

    The direct relationship between pulmonary structural changes and airway hyperresponsiveness (AHR) in chronic obstructive pulmonary disease (COPD) is unclear. We investigated AHR in relation to airway and parenchymal structural changes in a guinea pig model of COPD and in COPD patients. Precision-cut lung slices (PCLS) were prepared from guinea pigs challenged with lipopolysaccharide or saline two times weekly for 12 wk. Peripheral PCLS were obtained from patients with mild to moderate COPD and non-COPD controls. AHR to methacholine was measured in large and small airways using video-assisted microscopy. Airway smooth muscle mass and alveolar airspace size were determined in the same slices. A mathematical model was used to identify potential changes in biomechanical properties underlying AHR. In guinea pigs, lipopolysaccharide increased the sensitivity of large (>150 ÎŒm) airways toward methacholine by 4.4-fold and the maximal constriction of small airways

    Search for displaced vertices arising from decays of new heavy particles in 7 TeV pp collisions at ATLAS

    We present the results of a search for new, heavy particles that decay at a significant distance from their production point into a final state containing charged hadrons in association with a high-momentum muon. The search is conducted in a pp-collision data sample with a center-of-mass energy of 7 TeV and an integrated luminosity of 33 pb^-1 collected in 2010 by the ATLAS detector operating at the Large Hadron Collider. Production of such particles is expected in various scenarios of physics beyond the standard model. We observe no signal and place limits on the production cross-section of supersymmetric particles in an R-parity-violating scenario as a function of the neutralino lifetime. Limits are presented for different squark and neutralino masses, enabling extension of the limits to a variety of other models.Comment: 8 pages plus author list (20 pages total), 8 figures, 1 table, final version to appear in Physics Letters
