Correlation between Self-Esteem, Self-Efficacy, Personality, Fear of Success, and Self-Defeating Behaviors of Performing Artists

There is substantial evidence that self-defeating behaviors appear regularly among populations considered psychologically stable. While there has been abundant research on self-esteem, self-efficacy, personality traits, and fear of success as independent constructs, little is known regarding the combined effect of these constructs on the self-defeating behaviors of performing artists. Examining self-defeating behaviors among performing artists is significant because this population is susceptible to self-sabotaging behaviors, underscoring the need to understand their behaviors. The purpose of this quantitative correlational study was to examine whether self-esteem, self-efficacy, personality, and fear of success predicted self-defeating behaviors among performing artists. Bandura\u27s self-efficacy theory and the Baumeister self-esteem theory were used as the theoretical foundations for the study. A cross-sectional self-administered survey was used to collect data about how self-esteem, self-efficacy, personality, and fear of success affected the self-defeating behavior of performing artists from a convenience sample of 100 performing artists in New York City. The following assessment tools were used: Rosenberg Self-Esteem Scale, General Perceived Self-Efficacy Scale, Big Five Inventory, Fear of Success Scale, and the Lay Procrastination Scale. Results indicated a significant relationship between the self-efficacy, self-esteem, personality, and fear of success on self-defeating behavior in performance artists. The implications for positive social change include the potential to help current and future performing artists recognize and manage their self-defeating behaviors, thus preventing disengagement at work, depression, and frustration

An unexpected groin mass: Infant ovarian herniation

Point-of-care ultrasound provides a safe, rapid, effective, and accurate tool for  evaluating congenital groin masses in infants. We present a 4-week-old infant who presented to the emergency department with bilateral inguinal masses. Point-of-care ultrasonography discovered bilateral hernias with an ovary herniated through a patent processus vaginalis into the labium majora on the right side. The ovarian herniation reduced in the emergency department and the patient was discharged from the  emergency department after arranging close follow-up with a pediatric surgeon for a prompt repair. Its use should be employed early, as delayed discovery of ovarian herniation can lead to subsequent infertility.Keywords: hernia, ovary, pediatric, ultrasoun

Polysorbate 80 Inhibition of Pseudomonas aeruginosa Biofilm Formation and Its Cleavage by the Secreted Lipase LipA

Surface-associated bacterial communities known as biofilms are an important source of nosocomial infections. Microorganisms such as Pseudomonas aeruginosa can colonize the abiotic surfaces of medical implants, leading to chronic infections that are difficult to eradicate. Our study demonstrates that polysorbate 80 (PS80), a surfactant commonly added to food and medicines, is able to inhibit biofilm formation by P. aeruginosa on a variety of surfaces, including contact lenses

Increased typhoon activity in the Pacific deep tropics driven by Little Ice Age circulation changes

Increased typhoon activity in the Pacific deep tropics driven by Little Ice Age circulation changes. Nature Geoscience, 13, 806–811. doi:10.1038/s41561-020-00656-2.The instrumental record reveals that tropical cyclone activity is sensitive to oceanic and atmospheric variability on inter-annual and decadal scales. However, our understanding of the influence of climate on tropical cyclone behaviour is restricted by the short historical record and the sparseness of prehistorical reconstructions, particularly in the western North Pacific, where coastal communities suffer loss of life and livelihood from typhoons annually. Here, to explore past regional typhoon dynamics, we reconstruct three millennia of deep tropical North Pacific cyclogenesis. Combined with existing records, our reconstruction demonstrates that low-baseline typhoon activity prior to 1350 ce was followed by an interval of frequent storms during the Little Ice Age. This pattern, concurrent with hydroclimate proxy variability, suggests a centennial-scale link between Pacific hydroclimate and tropical cyclone climatology. An ensemble of global climate models demonstrates a migration of the Pacific Walker circulation and variability in two Pacific climate modes during the Little Ice Age, which probably contributed to enhanced tropical cyclone activity in the tropical western North Pacific. In the next century, projected changes to the Pacific Walker circulation and expansion of the tropics will invert these Little Ice Age hydroclimate trends, potentially reducing typhoon activity in the deep tropical Pacific.This work was supported by the Strategic Environmental Research and Development Program (SERDP RC-2336).

Inhomogeneous non-Gaussianity

We propose a method to probe higher-order correlators of the primordial density field through the inhomogeneity of local non-Gaussian parameters, such as f_NL, measured within smaller patches of the sky. Correlators between n-point functions measured in one patch of the sky and k-point functions measured in another patch depend upon the (n+k)-point functions over the entire sky. The inhomogeneity of non-Gaussian parameters may be a feasible way to detect or constrain higher-order correlators in local models of non-Gaussianity, as well as to distinguish between single and multiple-source scenarios for generating the primordial density perturbation, and more generally to probe the details of inflationary physics.Comment: 16 pages, 2 figures; v2: Minor changes and references added.

The Universal One-Loop Effective Action

We present the universal one-loop effective action for all operators of dimension up to six obtained by integrating out massive, non-degenerate multiplets. Our general expression may be applied to loops of heavy fermions or bosons, and has been checked against partial results available in the literature. The broad applicability of this approach simplifies one-loop matching from an ultraviolet model to a lower-energy effective field theory (EFT), a procedure which is now reduced to the evaluation of a combination of matrices in our universal expression, without any loop integrals to evaluate. We illustrate the relationship of our results to the Standard Model (SM) EFT, using as an example the supersymmetric stop and sbottom squark Lagrangian and extracting from our universal expression the Wilson coefficients of dimension-six operators composed of SM fields.Comment: 30 pages, v2 contains additional comments and corrects typos, version accepted for publication in JHE

Signal yields, energy resolution, and recombination fluctuations in liquid xenon

This work presents an analysis of monoenergetic electronic recoil peaks in the dark-matter-search and calibration data from the first underground science run of the Large Underground Xenon (LUX) detector. Liquid xenon charge and light yields for electronic recoil energies between 5.2 and 661.7 keV are measured, as well as the energy resolution for the LUX detector at those same energies. Additionally, there is an interpretation of existing measurements and descriptions of electron-ion recombination fluctuations in liquid xenon as limiting cases of a more general liquid xenon re- combination fluctuation model. Measurements of the standard deviation of these fluctuations at monoenergetic electronic recoil peaks exhibit a linear dependence on the number of ions for energy deposits up to 661.7 keV, consistent with previous LUX measurements between 2-16 keV with $^3$H. We highlight similarities in liquid xenon recombination for electronic and nuclear recoils with a comparison of recombination fluctuations measured with low-energy calibration data.Comment: 11 pages, 12 figures, 3 table
