Study to improve the low frequency noise characteristics of (Hg,Cd)Te detectors

Efforts made to identify and reduce the sources of l/f noise in 15 micron n-type (Hg,Cd)Te detectors operating at 77 K are reported. The investigation covered: evaluation of the influence of material properties and detector processing techniques, determination of the relative importance of surfaces, volumes, regions, and contracts, and generation of theoretical models for guidance of the experimental work

A Call for Comprehensive Perinatal Psychotherapy Training [English and Spanish versions]

Research has provided us with a tremendously rich understanding of the perinatal period and the kind of psychotherapeutic techniques that can effectively address issues that arise during this time. It is now time to more fully integrate and disseminate this knowledge to providers who are working with the perinatal population so it can be widely used in thoughtful and nuanced ways.

An Investigation into printing industry demographics—2009

What is the printing industry? The goal of this study is to discuss definitions for the U.S. printing industry and the “print universe.” The print universe is our term for an expanded view of establishments that produce some kind of reproduction as a service. There are about a dozen major sources of information about the printing industry with the primary source as the Federal Government. Printing is one of the most documented industries in the United States; yet, each of the sources arrives at a different view for the size and scope of the industry. This report investigates the challenges in developing a meaningful set of criteria for defining and quantifying the printing industry. Using a list compiled from Yellow Pages listings, we developed a database of 7,071 firms from the six New England states and New York State, and surveyed over 1,000 firms. The result is a snapshot of what the printing industry and the print universe are and how its demographics might be structured

Propaganda 2.0: Herman and Chomsky’s Propaganda Model in the Age of the Internet, Big Data and Social Media

"Thirty years after Chomsky and Herman elaborated the Propaganda Model this title aims to introduce a new generation of readers to it. It presents cutting-edge research demonstrating the model’s general validity as well as new attempts – in the light of digital media and 21st century politics – to critically update, expand, and refine it. International researchers thus analyse the continuities and new developments in media Environments throughout various regions of the world. Part I addresses the theoretical and methodological dimensions of the PM beginning with an interview with Edward Herman on the model itself. Part II reflects on propaganda as a concept and practice within new mediated digital communications systems and interfaces. Applications of the Propaganda Model are featured in Part III notably new forms of media and content not previously analysed within it: the entertainment industries through the analysis of television, professional sports, Hollywood movies and videogames using quantitative and qualitative research methods. The last section presents case studies of corporate media and reporting practices as reflections of elite power. An extensive re-visioning of the PM this book concludes by identifying the fundamental dimensions of the model, the key modifications and expansions that are suggested—such as the inclusion of new filters—whilst assessing the model’s overall value for conducting research in different geographical contexts and media systems and products.

River channel width controls blocking by slow-moving landslides in California's Franciscan melange

This is the final version. Available from European Geosciences Union via the DOI in this record. To explore the sensitivity of rivers to blocking from landslide debris, we exploit two similar geomorphic settings in California's Franciscan mélange where slow-moving landslides, often referred to as earthflows, impinge on river channels with drainage areas that differ by a factor of 30. Analysis of valley widths and river long profiles over ∼19 km of Alameda Creek (185 km2 drainage area) and Arroyo Hondo (200 km2 drainage area) in central California shows a very consistent picture in which earthflows that intersect these channels force tens of meters of gravel aggradation for kilometers upstream, leading to apparently long-lived sediment storage and channel burial at these sites. In contrast, over a ∼30 km section of the Eel River (5547 km2 drainage area), there are no knickpoints or aggradation upstream of locations where earthflows impinge on its channel. Hydraulic and hydrologic data from United States Geological Survey (USGS) gages on Arroyo Hondo and the Eel River, combined with measured size distributions of boulders input by landslides for both locations, suggest that landslide derived boulders are not mobile at either site during the largest floods (>2-year recurrence) with field-measured flow depths. We therefore argue that boulder transport capacity is an unlikely explanation for the observed difference in sensitivity to landslide inputs. At the same time, we find that earthflow fluxes per unit channel width are nearly identical for Oak Ridge earthflow on Arroyo Hondo, where evidence for blocking is clear, and for the Boulder Creek earthflow on the Eel River, where evidence for blocking is absent. These observations suggest that boulder supply is also an unlikely explanation for the observed morphological differences along the two rivers. Instead, we argue that the dramatically different sensitivity of the two locations to landslide blocking is related to differences in channel width relative to typical seasonal displacements of earthflows. A synthesis of seasonal earthflow displacements in the Franciscan mélange shows that the channel width of the Eel River is ∼5 times larger than the largest annual seasonal displacement. In contrast, during wet winters, earthflows are capable of crossing the entire channel width of Arroyo Hondo and Alameda Creek. In support of this interpretation, satellite imagery shows that immobile earthflow-derived boulders are generally confined to the edges of the channel on the Eel River. By contrast, immobile earthflow-derived boulders jam the entire channel on Arroyo Hondo. Our results imply that lower drainage area reaches of earthflow-dominated catchments may be particularly prone to blocking. By inhibiting the upstream propagation of base-level signals, valley-blocking earthflows may therefore promote the formation of so-called “relict topography”.National Science Foundatio

Media Theory, Public Relevance and the Propaganda Model

Since its initial formulation in 1988, the Herman-Chomsky Propaganda Model (PM) has become one of the most widely tested models of media performance in the social sciences. This is largely due to the combined efforts of a loose group of international scholars as well as an increasing number of students who have produced studies in the US, UK, Canadian, Australian, Japanese, Chinese, German, and Dutch contexts, amongst others. Yet, the PM has also been marginalised in media and communication scholarship, largely due to the fact that the PM‟s radical scholarly outlook challenges the liberal and conservative underpinnings of mainstream schools of thought in capitalist democracies. This paper brings together, for the first time, leading scholars to discuss important questions pertaining to the PM‟s origins, public relevance, connections to other approaches within Communication Studies and Cultural Studies, applicability in the social media age, as well as impact and influence. The paper aligns with the 30th anniversary of the PM and the publication of the collected volume, The Propaganda Model Today, and highlights the PM‟s continued relevance at a time of unprecedented corporate consolidation of the media, extreme levels of inequality and class conflict as well as emergence of new forms of authoritarianism
