Extra! Extra! This Just Thin: Identifying and Evaluating Framing of Obesity-Related News Coverage in Maine
Obesity is an important health issue, and understanding both its origins and its remedies is critical. More than 78 million people in the United States â more than one- third the nationâs population â are obese, making obesity one of the most newsworthy health concerns of the time. The first step in addressing public health issues is to inform the public, for which news media act as the primary source. However, news media overwhelmingly frame obesity reports through a lens of individual responsibility, which blames people for their eating habits while ignoring systemic factors of obesity such as food industry pressures, food insecurity, and low incomes. Maine has the highest rate of obesity in New England, with nearly 29 percent of adults in the state considered obese. News sources attribute individualsâ weight to their behaviors and largely ignore social constraints of individuals or other systemic responsibilities for addressing obesity. Frame analysis of articles from Maineâs four most prominent newspapers, the Portland Press Herald, Bangor Daily News, Morning Sentinel, and Sun Journal reveals the five dominant frames through which obesity is discussed. These frames include public health and a medicalized obesity âepidemic,â a stern or nurturing parental government, national identity and the âIdeal Americanâ citizen, the toxic environment of an overabundant industrial food system, âfunâ versus fear and sadness, and normative education. Taken together, these frames underscore a neoliberal discourse that works to support culturally- held values of national identity, masked by an illusion of choice
Investigation of OSB Thickness-Swell Based on a 3-D Density Distribution. Part II. Variations in Thickness-Swell and Internal Stresses
A recently developed finite element (FE) model was used to examine the thickness-swell, density changes, and internal stresses in oriented strandboard (OSB) panels under moisture loading. The model accounts for the nonlinear mechanical behavior of OSB and for the moisture transport through the specimen. The FE model is based on the 3-D density variation of the board. The density variation, resulting from manufacturing processes, affects the uniformity of thickness-swell in OSB and is often exacerbated by continuous sorption of moisture, which leads to potentially damaging internal stresses in the panel. The model was validated through comparison of experimental results. The use of the model is illustrated by quantifying the effects of resin content changes on thickness swell, and the examination of internal stresses and bond failures in an OSB specimen

Investigation of OSB Thickness-Swell Based on a 3d Density Distribution. Part I. The Finite Element Model
A finite element model was developed for predicting thickness-swell of oriented strandboard. The model accounts for both vertical and horizontal density variations of the board, or the three-dimensional density distribution. Density variation, resulting from manufacturing processes such as strand orientation and pressing cycles, affects the uniformity of thickness-swell in OSB. The model uses nonlinear constitutive behavior in the through-the-thickness direction. Moisture changes were modeled using transient moisture transfer equations and coupled moisture-density-stress-strain relations. The model was used to predict thickness-swell during a 24-h soak test. The model was able to predict average thicknes-swell of commercial panels with an acceptable error, generally less than 10%

Using mixed methods for analysing culture : The Cultural Capital and Social Exclusion project
This paper discusses the use of material generated in a mixed method investigation into cultural tastes and practices, conducted in Britain from 2003 to 2006, which employed a survey, focus groups and household interviews. The study analysed the patterning of cultural life across a number of fields, enhancing the empirical and methodological template provided by Bourdieuâs Distinction. Here we discuss criticisms of Bourdieu emerging from subsequent studies of class, culture and taste, outline the arguments related to the use of mixed methods and present illustrative results from the analysis of these different types of data. We discuss how the combination of quantitative and qualitative methods informed our analysis of cultural life in contemporary Britain. No single method was able to shed light on all aspects of our inquiry, lending support to the view that mixing methods is the most productive strategy for the investigation of complex social phenomena
Coupled Nd-142, Nd-143 and Hf-176 Isotopic Data from 3.6-3.9 Ga Rocks: New Constraints on the Timing of Early Terrestrial Chemical Reservoirs
Increasingly precise data from a range of isotopic decay schemes, including now extinct parent isotopes, from samples of the Earth, Mars, Moon and meteorites are rapidly revising our views of early planetary differentiation. Recognising Nd-142 isotopic variations in terrestrial rocks (which can only arise from events occurring during the lifetime of now extinct Sm-146 [t(sub 1/2)=103 myr]) has been an on-going quest starting with Harper and Jacobsen. The significance of Nd-142 variations is that they unequivocally reflect early silicate differentiation processes operating in the first 500 myr of Earth history, the key time period between accretion and the beginning of the rock record. The recent establishment of the existence of Nd-142 variations in ancient Earth materials has opened a new range of questions including, how widespread is the evidence of early differentiation, how do Nd-142 compositions vary with time, rock type and geographic setting, and, combined with other types of isotopic and geochemical data, what can Nd-142 isotopic variations reveal about the timing and mechanisms of early terrestrial differentiation? To explore these questions we are determining high precision Nd-142, Nd-143 and Hf-176 isotopic compositions from the oldest well preserved (3.63- 3.87 Ga), rock suites from the extensive early Archean terranes of southwest Greenland and western Australia
Spectrum of Sizes for Perfect Deletion-Correcting Codes
One peculiarity with deletion-correcting codes is that perfect
-deletion-correcting codes of the same length over the same alphabet can
have different numbers of codewords, because the balls of radius with
respect to the Levenshte\u{\i}n distance may be of different sizes. There is
interest, therefore, in determining all possible sizes of a perfect
-deletion-correcting code, given the length and the alphabet size~.
In this paper, we determine completely the spectrum of possible sizes for
perfect -ary 1-deletion-correcting codes of length three for all , and
perfect -ary 2-deletion-correcting codes of length four for almost all ,
leaving only a small finite number of cases in doubt.Comment: 23 page
HLA class I-redirected anti-tumour CD4+T-cells require a higher TCR binding affinity for optimal activity than CD8+T-cells
CD4+ T helper cells are a valuable component of the immune response towards cancer. Unfortunately, natural tumour-specific CD4+ T-cells occur in low frequency, express relatively low affinity T-cell receptors (TCRs) and show poor reactivity towards cognate antigen. In addition, the lack of human leukocyte antigen (HLA) class II expression on most cancers dictates that these cells are often unable to respond to tumour cells directly. These deficiencies can be overcome by transducing primary CD4+ T-cells with tumour-specific HLA class I-restricted TCRs prior to adoptive transfer. The lack of help from the coreceptor CD8 glycoprotein in CD4+ cells might result in these cells requiring a different optimal TCR binding affinity. Here we compared primary CD4+ and CD8+ T-cells expressing wildtype and a range of affinity-enhanced TCRs specific for the HLA A*0201-restricted NY-ESO-1- and gp100 tumour antigens. Our major findings are: (i) redirected primary CD4+ T-cells expressing TCRs of sufficiently high affinity exhibit a wide range of effector functions, including cytotoxicity, in response to cognate peptide; and, (ii) optimal TCR binding affinity is higher in CD4+ T-cells than CD8+ T-cells. These results indicate that the CD4+ T-cell component of current adoptive therapies using TCRs optimised for CD8+ T-cells is below par and that there is room for substantial improvement.

Investigating Perceptual Congruence Between Data and Display Dimensions in Sonification
The relationships between sounds and their perceived meaning and connotations are complex, making auditory perception an important factor to consider when designing sonification systems. Listeners often have a mental model of how a data variable should sound during sonification and this model is not considered in most data:sound mappings. This can lead to mappings that are difficult to use and can cause confusion. To investigate this issue, we conducted a magnitude estimation experiment to map how roughness, noise and pitch relate to the perceived magnitude of stress, error and danger. These parameters were chosen due to previous findings which suggest perceptual congruency between these auditory sensations and conceptual variables. Results from this experiment show that polarity and scaling preference are dependent on the data:sound mapping. This work provides polarity and scaling values that may be directly utilised by sonification designers to improve auditory displays in areas such as accessible and mobile computing, process-monitoring and biofeedback
