Democrats make more large spending cuts than Republicans because they must counteract their prior partisan increases in spending

The Democratic Party is characterized by its willingness to increase government spending to pursue their policy goals. However, when they do make cuts, Democrats tend to make more large cuts than Republicans. Sarah E. Anderson and Laurel Harbridge use data from U.S. budgetary spending reports from 1955-2002 to explain this paradox, arguing that Democrats make cuts as corrections to balance prior partisan decisions

Core Strength Testing: Developing Normative Data for Three Clinical Tests

BACKGROUND AND PURPOSE: The importance of core stability in activities of daily living, athletic performance, and in preventing low back pain (LBP) and extremity injuries is becoming increasingly accepted and better understood in modern literature. However, normative values for current core endurance tests have yet to be validated for clinic use. The purpose of this research project was to determine core endurance strength normative values for three core endurance tests in healthy men and women between the ages of 18 and 55 years old. METHODS: One-hundred-sixteen subjects (76 female and 40 male) with a mean age of 28.8 years participated in this study over a two-year period. Subjects completed a general health and exercise history questionnaire. Each subject was randomly assigned a test order and was tested by one of nine student researchers. The core endurance tests performed were the 60 degree flexion test (Fl), trunk extensor endurance test (Ext), right side plank (RSP), and left side plank (LSP). Analysis included a one-way ANOVA and multiple regression to determine differences between groups and to understand what variables influenced test outcomes. RESULTS: Normative mean values in seconds for each test are: Fl 160(102); Ext 101(51); RSP 54(25); LSP 55(28). One-way ANOVA revealed the following significant differences: gender M/F (RSP p=.00, LSP p=.00), exercise Y/N (RSP p=.03, LSP p=.01, Fl p=.000), active runners Y/N (RSP p=.001, LSP p=.005, Fl p=.001), strength training Y/N (RSP p=.001, LSP p=.000), core exercise Y/N (LSP p=.01), competitive athletes Y/N (RSP p=.01, LSP p=.02, Fl p=.04). Total time of all four tests noted significant differences for exercise Y/N (p=.005) and run Y/N (p=.003), but revealed no significant difference between gender. Multiple regression models revealed that exercise and core time were significant predictors of LSP. Exercise time was a significant predictor of Fl test, and age and waist circumference were significant predictors for Ext test. The overall model for RSP displayed a trend toward significance. CONCLUSION: Our results suggest that normative values can be established for the Fl and Ext tests regardless of gender, however RSP and LSP tests were significant for differences between genders. The results also suggest that increased activity level improved core endurance

Allergic Potential and Immunotoxicity Induced by Topical Application of 1-Chloro-4-(Trifluoromethyl)Benzene (PCBTF) in a Murine Model

The purpose of the studies in this paper was to evaluate the allergic potential, immunotoxicity, and irritancy of the occupationally relevant chemical, 1-chloro-4-(trifluoromethyl)benzene, also known as parachlorobenzotrifluoride (PCBTF), following dermal exposure in a murine model. Evaluation of the sensitization potential, conducted using the local lymph node assay (LLNA) at concentrations ranging from 50% to 100%, identified a dose-dependent increase in lymphocyte proliferation with a calculated EC3 value of 53.1%. While no elevations in total or specific IgE were observed after exposure to any concentration of the chemical, significant increases in IFN-γ protein production by stimulated draining lymphoid cells were observed, indicating a T-cell-mediated response. Dermal exposure to PCBTF was not found to alter the immune response to a T-cell-dependant antigen. These results demonstrate that PCBTF has the potential to induce allergic sensitization following dermal exposure and based on LLNA results would be classified as a weak sensitizer

Food Habits of Introduced Rodents in High-Elevation Shrubland of Haleakala National Park, Maui, Hawai'i

Mus musculus and Rattus rattus are ubiquitous consumers in the high-elevation shrubland of Haleakala National Park. Food habits of these two rodent species were determined from stomach samples obtained by snap-trapping along transects located at four different elevations during November 1984 and February, May, and August 1985. Mus musculus fed primarily on fruits, grass seeds, and arthropods. Rattus rattus ate various fruits, dicot leaves, and arthropods. Arthropods, many of which are endemic, were taken frequently by Mus musculus throughout the year at the highest elevation where plant food resources were scarce. Araneida, Lepidoptera (primarily larvae), Coleoptera, and Homoptera were the main arthropod taxa taken. These rodents, particularly Mus musculus, exert strong predation pressure on populations of arthropod species, including locally endemic species on upper Haleakala Volcano

Silicone Wristbands as Personal Passive Samplers

The author has paid this publisher's Open Access fee.Active-sampling approaches are commonly used for personal monitoring, but are limited by energy usage and data that may not represent an individual’s exposure or bioavailable concentrations. Current passive techniques often involve extensive preparation, or are developed for only a small number of targeted compounds. In this work, we present a novel application for measuring bioavailable exposure with silicone wristbands as personal passive samplers. Laboratory methodology affecting precleaning, infusion, and extraction were developed from commercially available silicone, and chromatographic background interference was reduced after solvent cleanup with good extraction efficiency (>96%). After finalizing laboratory methods, 49 compounds were sequestered during an ambient deployment which encompassed a diverse set of compounds including polycyclic aromatic hydrocarbons (PAHs), consumer products, personal care products, pesticides, phthalates, and other industrial compounds ranging in log K[subscript ow] from −0.07 (caffeine) to 9.49 (tris(2-ethylhexyl) phosphate). In two hot asphalt occupational settings, silicone personal samplers sequestered 25 PAHs during 8- and 40-h exposures, as well as 2 oxygenated-PAHs (benzofluorenone and fluorenone) suggesting temporal sensitivity over a single work day or week (p < 0.05, power =0.85). Additionally, the amount of PAH sequestered differed between worksites (p < 0.05, power = 0.99), suggesting spatial sensitivity using this novel application

Sleep duration partially accounts for race differences in diurnal cortisol dynamics

Objective: Emerging research demonstrates race differences in diurnal cortisol slope, an indicator of hypothalamic-pituitary-adrenocortical (HPA)-axis functioning associated with morbidity and mortality, with African Americans showing flatter diurnal slopes than their White counterparts. Sleep characteristics are associated with both race and with HPA-axis functioning. The present report examines whether sleep duration may account for race differences in cortisol dynamics. Method: Participants were 424 employed African American and White adults (mean age = 42.8 years, 84.2% White, 53.6% female) with no cardiovascular disease (Adult Health and Behavior Project—Phase 2 [AHAB-II] cohort, University of Pittsburgh). Cortisol slope was calculated using 4 salivary cortisol readings, averaged over each of 4 days. Demographic (age, sex), psychosocial (socioeconomic status [SES], affect, discrimination), and health behaviors (smoking, alcohol use, physical activity) variables were used as covariates, and sleep (self-report and accelerometry) was also assessed. Results: African Americans had flatter slopes than Whites (F(1, 411) = 10.45, B = .02, p = .001) in models adjusting for demographic, psychosocial, and health behavior covariates. Shorter actigraphy-assessed total sleep time was a second significant predictor of flatter cortisol slopes (F(1, 411) = 25.27, B = −.0002, p \u3c .0001). Total sleep time partially accounted for the relationship between race and diurnal slope [confidence interval = .05 (lower = .014, upper .04)]. Conclusions: African Americans have flatter diurnal cortisol slopes than their White counterparts, an effect that may be partially attributable to race differences in nightly sleep duration. Sleep parameters should be considered in further research on race and cortisol. (PsycINFO Database Record (c) 2017 APA, all rights reserved
