A uniform approach to field quantization

AbstractA new method for treating ordinary Bose and Fermi statistics as well as many types of parastatistics is proposed. Number operators are used to distinguish among different types of statistics, and uniqueness results for Bose, Fermi, parabose and parafermi statistics are obtained

The Nutritive Value of High Protein Oats, Double Mutant, Waxy, Opaque-2 and Normal Corns in Pig Starter Diets

The value of the mutant corns has been demonstrated in their ability to support superior performance of animals consuming them and in the need for less supplemental protein in diets containing he corns. Research conducted at South Dakota University showed that oats can constitute 60% of the grain portion of growing and finishing swine diets with less supplemental protein and no reduction in pig performance. The purpose of the research reported herein was to study the value of high protein oats in pig starter diets as well as availability of lysine in the grain. The inclusion of opaque-2, double mutant and waxy corns in starter diets was also evaluated. Rate of gain, feed consumption and feed efficiency were used as response criteria

Women and Men in Collaborative Working Partnerships: Connecting Two Disparate Modes of Experience

This study provides an in-depth description of mixed gender working partnerships in a collaborative effort over a one year period. The research identified differences between men and women in mutually collaborative working partnerships at the undergraduate level in order to also discover what was productive or problematic between those women and men in the partnerships. The research studied twenty-two UCSD undergraduate women and men who worked together in partnerships with mutual goals. The research utilized phenomenological interviewing techniques. The focus was the perceptions and experiences of the participants. The interviews were designed to address two primary research questions: 1) What contributes to a mutually agreeable and productive partnership between women and men engaged in collaborative work? 2) What is problematic between women and men engaged in collaborative work? The findings indicated that positive components for effective mixed gender partnerships included good communication, empowerment, constructive feedback, friendship, humor, common ground and intellectual growth and openness. Elements that were problematic were lack of initiative, poor communication, violation of confidentiality, sensitivity difference, relationships, different wavelengths , and sexist stereotypes. Gender differences figured prominently in partnership difficulties. Men were generally perceived as being less responsible, nurturing, detail oriented and self-starting than women. The specific work tasks required by the partnerships seemed to influence the outcomes. Recommendations based on the findings were to support mixed gender partnerships through gender awareness training, mediation, more accountability and supervisory intervention, facilitating an environment for common ground, reducing gender bias in performance standards, opportunities for social events, encouraging empowerment, and a commitment to affirmative action

microsynth: Synthetic Control Methods for Disaggregated and Micro-Level Data in R

The R package microsynth has been developed for implementation of the synthetic control methodology for comparative case studies involving micro- or meso-level data. The methodology implemented within microsynth is designed to assess the efficacy of a treatment or intervention within a well-defined geographic region that is itself a composite of several smaller regions (where data are available at the more granular level for comparison regions as well). The effect of the intervention on one or more time-varying outcomes is evaluated by determining a synthetic control region that resembles the treatment region across pre-intervention values of the outcome(s) and time-invariant covariates and that is a weighted composite of many untreated comparison regions. The microsynth procedure includes functionality that enables its user to (1) calculate weights for synthetic control, (2) tabulate results for statistical inferences, and (3) create time series plots of outcomes for treatment and synthetic control. In this article, microsynth is described in detail and its application is illustrated using data from a drug market intervention in Seattle, WA

Fairness and distributive justice by 3- to 5-year-old Tibetan children

We asked whether young children raised in an environment strongly promoting compassion for others, as in the case of Tibetan Buddhism, would show less proclivity toward self-maximizing in sharing. We replicated the procedure of Rochat et al. with a group of 3- and 5-year-old Tibetan children living in exile and attending a traditional Buddhist school where the Dalai Lama resides. We report that Tibetan children, like children of seven other cultures, start from a marked self-maximizing propensity at 3 years of age, becoming significantly more fair by 5 years. These data confirm that the developing sense of equity by young children is comparable in the context of a compassion-based culture.PostprintPeer reviewe

Association of egg consumption and calcified atherosclerotic plaque in the coronary arteries: The NHLBI Family Heart Study

pre-printBackground and Aims: Eggs are a ubiquitous and important source of dietary cholesterol and nutrients, yet their relationship to coronary heart disease (CHD) remains unclear. While some data have suggested a positive association between egg consumption and CHD, especially among diabetic subjects, limited data exist on the influence of egg consumption on subclinical disease. Thus, we sought to examine whether egg consumption is associated with calcified atherosclerotic plaques in the coronary arteries. Methods: In a cross-sectional design, we studied 1848 participants of the NHLBI Family Heart Study without known CHD. Egg consumption was assessed by a semi-quantitative food frequency questionnaire and coronary-artery calcium (CAC) was measured by cardiac CT. We defined prevalent CAC using an Agatston score of at least 100 and fitted generalized estimating equations to calculate prevalence odds ratios of CAC. Results: Mean age was 56.5 years and 41% were male. Median consumption of eggs was 1/week. There was no association between frequency of egg consumption and prevalent CAC. Odds ratios (95% CI) for CAC were 1.0 (reference), 0.95 (0.66-1.38), 0.94 (0.63-1.40), and 0.90 (0.57-1.42) for egg consumption of almost never, 1-3 times per month, once per week, and 2+ times per week, respectively (p for trend 0.66), adjusting for age, sex, BMI, smoking, alcohol, physical activity, income, field center, total calories, and bacon

Comparative genome-centric analysis reveals seasonal variation in the function of coral reef microbiomes

Microbially mediated processes contribute to coral reef resilience yet, despite extensive characterisation of microbial community variation following environmental perturbation, the effect on microbiome function is poorly understood. We undertook metagenomic sequencing of sponge, macroalgae and seawater microbiomes from a macroalgae-dominated inshore coral reef to define their functional potential and evaluate seasonal shifts in microbially mediated processes. In total, 125 high-quality metagenome-assembled genomes were reconstructed, spanning 15 bacterial and 3 archaeal phyla. Multivariate analysis of the genomes relative abundance revealed changes in the functional potential of reef microbiomes in relation to seasonal environmental fluctuations (e.g. macroalgae biomass, temperature). For example, a shift from Alphaproteobacteria to Bacteroidota-dominated seawater microbiomes occurred during summer, resulting in an increased genomic potential to degrade macroalgal-derived polysaccharides. An 85% reduction of Chloroflexota was observed in the sponge microbiome during summer, with potential consequences for nutrition, waste product removal, and detoxification in the sponge holobiont. A shift in the Firmicutes:Bacteroidota ratio was detected on macroalgae over summer with potential implications for polysaccharide degradation in macroalgal microbiomes. These results highlight that seasonal shifts in the dominant microbial taxa alter the functional repertoire of host-associated and seawater microbiomes, and highlight how environmental perturbation can affect microbially mediated processes in coral reef ecosystems.Australian Government Department of Industry, Innovation and Science; Advance Queensland PhD Scholarship Great Barrier Reef Marine Park Authority Management Award National Environmental Science Program (NESP)info:eu-repo/semantics/publishedVersio
