Positive : a semantic analysis of the word positive. The dichomotomic relation between individual and collective language-meaning construction in postmodern capitalism by Marina Cortés( )

1 edition published in 2020 in English and held by 1 WorldCat member library worldwide

This paper explores the dichotomy of individual and collective construction of word-meaning in the term "positive" in reference to its HIV and psychological positivity denotations and its relation to the internet and Postmodern, more specifically, liquid modernity capitalism. Through an assessment of cognitive linguistics, Structuralist lexical theory, individual narrative, empirical data, historical analysis of the HIV/Aids epidemic movement in America and Postmodern critical philosophy, the paper observes how collective assimilation of a word in a unique context can give rise to an alienating paradigm to serve political hegemonies: for example, the notion of positivity serving to support the perpetuation of capitalism. The essay dives into the mechanisms or platforms that perpetuate and condition collective thinking emphasizing the role of the internet and biomedical authority. Essentially, the thesis challenges how the collective cognitive conceptualization of the word erases important denotations and narratives associated with the term ""positive"" that are incredibly significant to dissident and often invisibilized individuals

Does heart rate variability reflect the systemic inflammatory response in a fetal sheep model of lipopolysaccharide-induced sepsis?( )

1 edition published in 2015 in English and held by 1 WorldCat member library worldwide

Abstract: Fetal inflammatory response occurs during chorioamnionitis, a frequent and often subclinical inflammation associated with increased risk for brain injury and life-lasting neurologic deficits. No means of early detection exist. We hypothesized that systemic fetal inflammation without septic shock will be reflected in alterations of fetal heart rate (FHR) variability (fHRV) distinguishing baseline versus inflammatory response states. In chronically instrumented near-term fetal sheep (n = 24), we induced an inflammatory response with lipopolysaccharide (LPS) injected intravenously (n = 14). Ten additional fetuses served as controls. We measured fetal plasma inflammatory cytokine IL-6 at baseline, 1, 3, 6, 24 and 48 h. 44 fHRV measures were determined continuously every 5 min using continuous individualized multi-organ variability analysis (CIMVA). CIMVA creates an fHRV measures matrix across five signal-analytical domains, thus describing complementary properties of fHRV. Using principal component analysis (PCA), a widely used technique for dimensionality reduction, we derived and quantitatively compared the CIMVA fHRV PCA signatures of inflammatory response in LPS and control groups. In the LPS group, IL-6 peaked at 3 h. In parallel, PCA-derived fHRV composite measures revealed a significant difference between LPS and control group at different time points. For the LPS group, a sharp increase compared to baseline levels was observed between 3 h and 6 h, and then abating to baseline levels, thus tracking closely the IL-6 inflammatory profile. This pattern was not observed in the control group. We also show that a preselection of fHRV measures prior to the PCA can potentially increase the difference between LPS and control groups, as early as 1 h post LPS injection. We propose a fHRV composite measure that correlates well with levels of inflammation and tracks well its temporal profile. Our results highlight the potential role of HRV to study and monitor the inflammatory response non-invasively over time
The Eighth Data Release of the Sloan Digital Sky Survey : First Data from SDSS-III by Hiroaki Aihara( Book )

1 edition published in 2011 in English and held by 1 WorldCat member library worldwide

"The Sloan Digital Sky Survey (SDSS) started a new phase in 2008 August, with new instrumentation and new surveys focused on Galactic structure and chemical evolution, measurements of the baryon oscillation feature in the clustering of galaxies and the quasar Ly[Greek letter alpha] forest, and a radial velocity search for planets around ~8000 stars. This paper describes the first data release of SDSS-III (and the eighth counting from the beginning of the SDSS). The release includes five-band imaging of roughly 5200 deg2 in the southern Galactic cap, bringing the total footprint of the SDSS imaging to 14,555 deg2, or over a third of the Celestial Sphere. All the imaging data have been reprocessed with an improved sky-subtraction algorithm and a final, self-consistent photometric recalibration and flat-field determination. This release also includes all data from the second phase of the Sloan Extension for Galactic Understanding and Exploration (SEGUE-2), consisting of spectroscopy of approximately 118,000 stars at both high and low Galactic latitudes. All the more than half a million stellar spectra obtained with the SDSS spectrograph have been reprocessed through an improved stellar parameter pipeline, which has better determinationof metallicity for high-metallicity stars."
