How Selective Amnesia Brought Us The First Black Socialist President Of The United States, Kristen Hoerl

Department of Communication Studies: Faculty Publications

Post-Racial Amnesia during President Obama’s 2008 Inauguration

My interest in public memory explains why news coverage leading up to President Obama’s inauguration rankled me. The endless news cycle kept repeating trite statements that announced that the civil rights struggle had ended. Reports quoted public officials and former civil rights activists who described Obama’s election as the “fulfillment,” “embodiment,” “culmination,” and “validation” of Martin Luther King Jr.’s dream. The inauguration took place the day after Martin Luther King Day, and Obama delivered a pre-inauguration address in front of the Lincoln Memorial, the same location where King delivered his 1963 speech. Given …

Postmodern/Poststructural Approaches, Jennifer J. Mease (Also Peeksmease)

Department of Communication Studies: Faculty Publications

Postmodern and poststructural approaches to organizational communication are marked by an emphasis on ruptures, disjunctions, tensions, instabilities, and other inconsistencies as a part of everyday organizational life. This emphasis is part of an attempt to question, critique, and often compromise the normalized, mundane power structures that regulate organizational life. By questioning and critiquing, these approaches reveal norms and power structures as contingently constructed with particular interests at play. This contrasts with more traditional assumptions that treat norms and power structures as natural, neutral, and stable constructions.

Poststructural and postmodern approaches to organizational communication find their roots in broader philosophical movements …

Reply To ‘On The Bonding In Ligand-Protected Gold Clusters’, Wen Wu Xu, Xiao Cheng Zeng, Yi Gao

Xiao Cheng Zeng Publications

In the recent Correspondence, Professor Henrik Grönbeck made several comments on the recently developed grand unified model (GUM), in particular using the ligand-protected gold cluster [Au₂₅(SR)₁₈]¹⁻ as an example. We noted that the latter cluster can be viewed as belonging to a special group of ligand-protected gold clusters that contain one or several icosahedral Au₁₃ motifs. For this group of clusters, a secondary block Au₁₃(8e) has been identified as a more convenient way to describe their structure anatomy and evolution. Another extension of the GUM is the identification of the new elementary …

Turkish Journal of Medical Sciences

Background/aim: This study aimed to report invasive cribriform carcinoma (ICC) with radiological and histopathologic correlations. Materials and methods: Seventy patients with ICC were classified into two groups; pure ICC patients and patients with >50% cribriform carcinoma component were included in group 1, while patients with <50% cribriform carcinoma component were included in group 2. All patients were reviewed according to American College of Radiology (ACR) breast imaging reporting and data system (BI-RADS) lexicon of mammography (MG), ultrasonography (US), and magnetic resonance imaging (MRI). One-way analysis of variance tests and t-tests were used for analysis. P < 0.05 was accepted as statistically significant. Results: Eighteen patients were in group 1 and 52 were in group 2. All patients had MG and US, while 24 patients needed MRI. According to MG ACR BI-RADS lexicon evaluation, irregular shape, spiculated margin and indistinct margin, and high density were statistically significantly higher in group 2 than the other group (respectively P = 0.001, P = 0.001, and P= 0.04). Equal density was statistically significantly higher in group 1 than the other group (P = 0.008). According to US ACR BI-RADS lexicon evaluation, irregular shape, spiculated margins, angular margins, microlobulated margins, and nonparallel orientation were more common US findings in group 2 than the other group (respectively P = 0.001, P = 0.001, P = 0.003, P = 0.04, and P = 0.04). The rate of parallel orientation was higher in group 1 than the other group (P = 0.02). Conclusion: Few cases showed benign characteristics and most ICCs appear with typical features of malignancy. Radiologic features of ICC could be better understood and would be helpful for radiologists in diagnosing this rare type of malignancy.
