LISA SERGIO: HOW MUSSOLINI'S "GOLDEN VOICE" OF PROPAGANDA CREATED AN AMERICAN MASS COMMUNICATION CAREER

In 1937 Lisa Sergio, "The Golden Voice" of fascist broadcasting from Rome, fled Italy for the United States. Though her mother was American, Sergio was classified as an enemy alien once the United States entered World War II. Yet Sergio became a U.S. citizen in 1944 and built a successful career in radio, working first at NBC and then WQXR in New York City in the days when women's voices were not thought to be appropriate for news or "serious" programming. When she was blacklisted as a communist in the early 1950s, Sergio compensated for the loss of radio employment by becoming principally an author and lecturer in Washington, D.C., until her death in 1989. This dissertation, based on her personal papers, is the first study of Sergio's American mass communication career. It points out the personal, political and social obstacles she faced as a woman in her 52-year career as a commentator on varied aspects of world affairs, religion and feminism. This study includes an examination of the FBI investigations of Sergio and the anti-communist campaigns conducted against her. It concludes that Sergio's success as a public communicator was predicated on both her unusual talents and her ability to transform her public image to reflect ideal American values of womanhood in shifting political climates.

Deposition of silver nanoparticles in geochemically heterogeneous porous media: predicting affinity from surface composition analysis.

The transport of uncoated silver nanoparticles (AgNPs) in a porous medium composed of silica glass beads modified with a partial coverage of iron oxide (hematite) was studied and compared to that in a porous medium composed of unmodified glass beads (GB). At a pH lower than the point of zero charge (PZC) of hematite, the affinity of AgNPs for a hematite-coated glass bead (FeO-GB) surface was significantly higher than that for an uncoated surface. There was a linear correlation between the average nanoparticle affinity for media composed of mixtures of FeO-GB and GB collectors and the relative composition of those media as quantified by the attachment efficiency over a range of mixing mass ratios of the two types of collectors, so that the average AgNPs affinity for these media is readily predicted from the mass (or surface) weighted average of affinities for each of the surface types. X-ray photoelectron spectroscopy (XPS) was used to quantify the composition of the collector surface as a basis for predicting the affinity between the nanoparticles for a heterogeneous collector surface. A correlation was also observed between the local abundances of AgNPs and FeO on the collector surface.

Coupled 3-D finite difference time domain and finite volume methods for solving microwave heating in porous media

Computational results for the microwave heating of a porous material are presented in this paper. Combined finite difference time domain and finite volume methods were used to solve equations that describe the electromagnetic field and heat and mass transfer in porous media. The coupling between the two schemes is through a change in dielectric properties which were assumed to be dependent both on temperature and moisture content. The model was able to reflect the evolution of temperature and moisture fields as the moisture in the porous medium evaporates. Moisture movement results from internal pressure gradients produced by the internal heating and phase change.

Heat and mass transfer in two-phase porous materials under intensive microwave heating

Computational results for the intensive microwave heating of porous materials are presented in this work. A multi-phase porous media model has been developed to predict the heating mechanism. Combined finite difference time-domain and finite volume methods were used to solve equations that describe the electromagnetic field and heat and mass transfer in porous media. The coupling between the two schemes is through a change in dielectric properties which were assumed to be dependent both on temperature and moisture content. The model was able to reflect the evolution of both temperature and moisture fields as well as energy penetration as the moisture in the porous medium evaporates. Moisture movement results from internal pressure gradients produced by the internal heating and phase change.

A new poetics of exile and belonging: the place of memory in the new media environment

This paper explores how new media environments represent and create collective memories of trauma; how creative digital practice can be a key methodology for memory studies and the potential of digital interfaces for representing and reconciling collective memories of trauma, particularly in the context of Cyprus. My project MemoryBank will be used as a model to discuss the potential role of creative digital media practice in both community arts and the formal education process in order to enable participants to engage with the process of peace and reconciliation in Cyprus and circumvent and negotiate politically ossified collective memory narratives and chauvinistic histories.

Political Discourse and Conflict Resolution:Debating peace in Northern Ireland

This book offers new insights into the close relationship between political discourses and conflict resolution through critical analysis of the role of discursive change in a peace process.

Just as a peace process has many dimensions and stakeholders, so the discourses considered here come from a wide range of sources and actors. The book contains in-depth analyses of official discourses used to present the peace process, the discourses of political party leaders engaging (or otherwise) with it, the discourses of community-level activists responding to it, and the discourses of the media and the academy commenting on it. These discourses reflect varying levels of support for the peace process – from obstruction to promotion – and the role of language in moving across this spectrum according to issue and occasion. Common to all these analyses is the conviction that the language used by political protagonists and cultural stakeholders has a profound effect on progression towards peace.

Bringing together leading experts on Northern Ireland’s peace process from a range of academic disciplines, including political science, sociology, linguistics, history, geography, law, and peace studies, this book offers new insights into the discursive dynamics of violent political conflict and its resolution.

“That’s not Ironic, that’s just Stupid!": Towards an Eclectic Account of the Discourse of Irony

This article draws on a range of models from language studies, particularly from linguistic pragmatics, in order to elucidate patterns in the production and reception of irony in its social and cultural context. An expanded view of the concept of irony, it is suggested, allows for better modelling of the creative mechanisms which underpin it, and in doing so can open the way for a fuller understanding of humour production and reception. A consequence of this broader (five-fold) typology of irony is that it can help shed light on the cultural dynamic of irony. The article uses a range of examples from different media and the lay definitions and interpretations that ordinary (non-academic) users of the language use in the comprehension of irony. Insofar as it seeks to develop an overarching model of irony, this paper draws on a variety of textual examples from a variety of sources, ranging from corpus evidence, through a stand-up comedy routine, to political wall murals and their discursive re-conformation as humour in present-day Northern Ireland. Although the central discussion is supported by insights from other linguistic, cognitive and socio-cultural approaches, the theoretical framework which emerges, with its focus on language and communication in context, is situated squarely within contemporary linguistic pragmatics.

Kinetics and mechanism of a macrocyclic chromium(III) complex oxidation to chromium(IV) by hexacyanoferrate(III) in strongly alkaline media

Oxidation of the macrocyclic Cr(III) complex cis-[Cr(cycb)(OH)(2)](+), where cycb = rac-5,5,7,12,12,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane, by an excess of the hexacyanoferrate( III) in basic solution, slowly produces Cr(V) species. These species, detected using e.p.r. spectroscopy, are stable under ambient conditions for many hours, and the hyperfine structure of the e.p.r. spectrum is consistent with the interaction of the d-electron with four equivalent nitrogen nuclei. Electro-spray ionization mass spectrometry suggests a concomitant oxidation of the macrocyclic ligand, in which double bonds and double bonded oxygen atoms have been introduced. By comparison basic chromate(III) solutions are oxidized rapidly to chromate(VI) by hexacyanoferrate(III) without any detectable generation of stable Cr(V) intermediates.

Quantifying mircoorganism/organic matter interactions in saturated porous media.

Proteins and humic acids are common constituents of waste water. Latex colloids (colloids) acted as surrogates for microorganisms in multiple pulse dynamic column experiments (MPEs) that permitted colloid mobility to be quantified before and after the injection of either BSA (a protein), or Suwannee River humic acid (SRHA).
At low OM coverage colloid breakthrough curves demonstrated both BSA and SRHA reduced colloid deposition rates, but did not affect colloid irreversible deposition mechanisms. By contrast, high levels of SRHA surface coverage not only further reduced the matrix’s ability to attenuate colloids, but also resulted in reversible adsorption of a significant fraction of colloids deposited. Modelling of colloid responses using random sequential adsorption modelling suggested that 1 microgram of SRHA had the same effect as the deposition of 5.90±0.14 x109 colloids; the model suggested that adsorption of the same mass of BSA was equivalent to the deposition of between 7.1x108 and 2.3x109 colloids.
Colloid responses in MPEs where BSA coverage of colloid deposition sites approached saturation demonstrated the sand matrix remained capable of adsorbing colloids. However, in contrast to responses observed in MPEs at low surface coverage, continued colloid injection showed that the sand’s attenuation capacity increased with time, i.e. colloid concentrations declined as more were deposited (filter ripening).
Importance: Study results highlight the contrasting responses that may arise due to the interactions between colloids and OM in porous media. Results not only underscore that colloids can interact differently with various forms of deposited OM, but also that a single type of OM may generate dramatically different responses depending on the degree of surface coverage. The MPE method provides a means of quantifying the influence of OM on microorganism mobility in porous media such as filter beds, which may be used for either drinking water treatment or waste water treatment. In the wider environment study findings have potential to allow more confident predictions of the mobility of sewage derived pathogens discharging to groundwater.

Housing booms and media coverage

This article analyses news media coverage of the housing market. Building on theories of media influence where word of mouth is the final mechanism of opinion change but media initiate discourse, I examine the relationship between news media and the recent UK house price boom. Over 30 000 articles on the UK housing market from the period 1993 to 2008 are analysed, and it is found that media Granger-caused real house price changes, suggesting the media may have influenced opinions on the housing market. However, media sentiment on the housing market did not change with the secular increase in house prices in the 2000s, suggesting that the media did not contribute to the UK’s housing boom and may have helped constrain it.

Institutional Discourse

Institutions (and how they work) have long been the object of many investigations in the fields of media, cultural, and organizational studies. More recently, there has been a “linguistic” turn in the study of institutions with many language-focused explo- rations of how power and discourse may function in specific institutional and organi- zational settings, such as schools, courtrooms, corporations, clinics, hospitals, and pris- ons. Many of these studies have been concerned with the ways in which language is used to create and shape institutions and how institutions in turn have the capacity to create, shape, and impose discourses on people. Institutions thus have considerable control over the organizing of our routine experiences of the world and the way we classify that world. They also have the power to foster particular kinds of identities to suit their own purposes.

Nuclear magnetic resonance-determined lipoprotein subclasses and carotid intima-media thickness in type 1 diabetes

BACKGROUND: Dyslipidemia has been linked to vascular complications of Type 1 diabetes (T1DM). We investigated the prospective associations of nuclear magnetic resonance-determined lipoprotein subclass profiles (NMR-LSP) and conventional lipid profiles with carotid intima-media thickness (IMT) in T1DM.

METHODS: NMR-LSP and conventional lipids were measured in a subset of Diabetes Control and Complications Trial (DCCT) participants (n = 455) at study entry ('baseline', 1983-89), and were related to carotid IMT determined by ultrasonography during the observational follow-up of the DCCT, the Epidemiology of Diabetes Interventions and Complications (EDIC) study, at EDIC Year 12 (2004-2006). Associations were defined using multiple linear regression stratified by gender, and following adjustment for HbA1c, diabetes duration, body mass index, albuminuria, DCCT randomization group, smoking status, statin use, and ultrasound devices.

RESULTS: In men, significant positive associations were observed between some baseline NMR-subclasses of LDL (total IDL/LDL and large LDL) and common and/or internal carotid IMT, and between conventional total- and LDL-cholesterol and non-HDL-cholesterol and common carotid IMT, at EDIC Year 12; these persisted in adjusted analyses (p < 0.05). Large LDL particles and conventional triglycerides were positively associated with common carotid IMT changes over 12 years (p < 0.05). Inverse associations of mean HDL diameter and large HDL concentrations, and positive associations of small LDL with common and/or internal carotid IMT (all p < 0.05) were found, but did not persist in adjusted analyses. No significant associations were observed in women.

CONCLUSION: NMR-LSP-derived LDL particles, in addition to conventional lipid profiles, may help in identifying men with T1DM at highest risk for vascular disease.

The New Instantaneity: How Social Media are Helping us Privilege the (Politically) Correct over the True

The recent sacking of the eminent scientist Tim Hunt from one of the UK’s leading research institutions is only the latest in a series of cases where public individuals have been derided for comments made in jest on social media, with serious consequences for their professional and personal lives. This article discusses the case of Tim Hunt as an example of the extent to which the privileging of the correct over the true which has long pervaded media discourse is taken to the extreme by the instant-response culture of social media. It points to the emergence of a new form of instantaneity enabled by these networked forms of communication that serves to reinforce systemic inaction rather than the change widely associated with these technologies. It draws on philosophy and Critical Theory as useful conceptual frameworks for highlighting the ways in which Twitter & co. increasingly call us to action but crowd out thought, thereby passing over opportunities for real social change.
