Conspiracy theorists helped the Parkland students keep gun control on the national agenda

In the wake of the mass shooting at Marjory Stoneman Douglas High School in Parkland, Florida, gun control has remained on the political and media agendas for far longer than has been the case following similar events in the past. Joseph E. Uscinski, Darin DeWitt, and Matthew D. Atkinson argue that this shooting has continued to capture the nation's attention because of the conspiracy theory narratives that surround it. The politically strategic Parkland students have benefited from the public attention generated by conspiracy theorists – who accuse the students of being ‘crisis actors’ – to remain in the media spotlight and keep the issue of gun control on the national agenda

Just like previous presidents, Donald Trump's political fortunes rise and fall with the economy

In spite of an ever-growing list of scandals and criminal indictments, President Trump's job approval rating has rallied from its December nadir. Trump's approval rating is now in the low 40s - where Reagan's and Clinton's approval stood around the time of their first midterm elections. Given Trump's controversial statements and the various crises which have gripped the White House since the inauguration, why is the 45th president’s approval rating so high? Matthew D. Atkinson, Darin DeWitt, and Joseph E. Uscinski find that, as has been the case with past US presidents, Trump’s approval rate ebbs and flows with the public’s perception of the economy. A relatively buoyant economy, they write, is keeping Trump’s approval rating higher than it might otherwise be. This says something particularly damning not just about approval ratings, but about voters, elections, and democracy as well

The Short Rotation Period of Hi'iaka, Haumea's Largest Satellite

Hi'iaka is the larger outer satellite of the dwarf planet Haumea. Using relative photometry from the Hubble Space Telescope and Magellan and a phase dispersion minimization analysis, we have identified the rotation period of Hi'iaka to be ~9.8 hrs (double-peaked). This is ~120 times faster than its orbital period, creating new questions about the formation of this system and possible tidal evolution. The rapid rotation suggests that Hi'iaka could have a significant obliquity and spin precession that could be visible in light curves within a few years. We then turn to an investigation of what we learn about the (presently unclear) formation of the Haumea system and family based on this unexpectedly rapid rotation rate. We explore the importance of the initial semi-major axis and rotation period in tidal evolution theory and find they strongly influence the time required to despin to synchronous rotation, relevant to understanding a wide variety of satellite and binary systems. We find that despinning tides do not necessarily lead to synchronous spin periods for Hi'iaka, even if it formed near the Roche limit. Therefore the short rotation period of Hi'iaka does not rule out significant tidal evolution. Hi'iaka's spin period is also consistent with formation near its current location and spin up due to Haumea-centric impactors.Comment: 21 pages with 6 figures, to be published in The Astronomical Journa

Stroke Quality Measures in Mexican Americans and Non-Hispanic Whites

Mexican Americans (MAs) have been shown to have worse outcomes after stroke than non-Hispanic Whites (NHWs), but it is unknown if ethnic differences in stroke quality of care may contribute to these worse outcomes. We investigated ethnic differences in the quality of inpatient stroke care between MAs and NHWs within the population-based prospective Brain Attack Surveillance in Corpus Christi (BASIC) Project (February 2009- June 2012). Quality measures for inpatient stroke care, based on the 2008 Joint Commission Primary Stroke Center definitions were assessed from the medical record by a trained abstractor. Two summary measure of overall quality were also created (binary measure of defect-free care and the proportion of measures achieved for which the patient was eligible). 757 individuals were included (480 MAs and 277 NHWs). MAs were younger, more likely to have hypertension and diabetes, and less likely to have atrial fibrillation than NHWs. MAs were less likely than NHWs to receive tPA (RR: 0.72, 95% confidence interval (CI) 0.52, 0.98), and MAs with atrial fibrillation were less likely to receive anticoagulant medications at discharge than NHWs (RR 0.73, 95% CI 0.58, 0.94). There were no ethnic differences in the other individual quality measures, or in the two summary measures assessing overall quality. In conclusion, there were no ethnic differences in the overall quality of stroke care between MAs and NHWs, though ethnic differences were seen in the proportion of patients who received tPA and anticoagulant at discharge for atrial fibrillation

Prevalence, gender correlates, and co-morbidity of trichotillomania.

Trichotillomania is a mental health condition characterized by repetitive pulling out of one's hair, often leading to functional impairment and/or distress. A convenience sampling of 10,169 adults, aged 18-69 years, representative of the general US population, completed a survey to establish occurrence of trichotillomania, other mental health concerns, and impact of the illness. 175 (1.7%) identified as having current trichotillomania. Rates of trichotillomania did not differ significantly based on gender (1.8% of males and 1.7% of females). The mean age of onset for trichotillomania was 17.7 years. The mean age of onset differed significantly for males (mean 19.0 years) versus females (mean 14.8 years (p = 0.020). The average amount of distress reported due to trichotillomania was relatively high, and 79% of people with trichotillomania had one or more mental health comorbidities, the most common being anxiety/depressive disorders, OCD, PTSD, and ADHD. This study suggests trichotillomania is relatively common in the general population and typically characterized by moderate-high distress and high rates of comorbidity

Binder containing plant protein and densified refuse fuel cubes made using same and methods of making them

To form a binder from naturally occurring products or a fuel brick or pellet using the binder without extraction or purification steps, the binder utilizes proteins from the germ or endosperm of cereal grasses or from the seed of buckwheat, oil seed plants, Amaranthus or leguminous plants or from leaves or from grain stillage. The protein has a thermoplastic microstructure with linear polymers of molecular weight of at least 2,000 linked with peptide linkages of at least 50 in number. The binder is mixed with waste such as municipal waste without further processing and processed in a pelleting machine

Patient outcomes influenced by reduced lymphocyte counts after dimethyl fumarate initiation

Objective: To examine the temporal profile of absolute and lymphocyte subset data from dimethyl fumarate (DMF) start and relationships to disease behavior. Methods: A retrospective study performed on patients with an existing diagnosis of MS and a history of DMF exposure from a single MS center. Demographic, laboratory, and corresponding clinical relapse and MRI data were recorded from baseline and in 3-4-month intervals after treatment initiation extending to 3 years. The Spearman rank coefficient and mixed-effects models were used to assess longitudinal correlations between cell counts and measures of disease activity. Results: A total of 292 patients with MS (228 women; median age at DMF initiation: 40.6 years, range: 16.1-66.7 years) were identified. An increased risk of disease activity was associated with higher absolute lymphocyte count (ALC) values at 3 months (p = 0.001, OR: 1.82) and at 6 months (p = 0.032, hazard ratio: 1.73). A reduced risk of disease evolution in patients with lower ALC values < 1,200 cells/L compared with midtier (1,210-1,800 cells/L) and the highest tertile (>1,810 cells/L) was observed (p = 0.01). Conclusions: Reductions in ALC values at months 3 and 6 after treatment initiation appear to be associated with improved clinical and radiologic outcomes. These data alone may help to provide a better understanding of both the safety and efficacy of DMF
