Emotional and Spiritual Well-Being as Predictors of Burnout Among Doctoral Clinical Psychology Trainees

It has been observed in prior studies that student spiritual engagement and attribution tends to decline throughout graduate clinical training in psychology (Eisele, 2016; Fisk et al., 2013). This is problematic considering the inverse relationship between spirituality and stress (Calicchia & Graham, 2006) and the protection it provides against burnout. Also protective against burnout, and correlated with spirituality, is Emotional Intelligence (EI; Kaur, Sambasivan, & Kumar, 2013). Both EI and spirituality are related to lower burnout, less depression, and greater life-satisfaction (Kroska et al., 2017). Despite burnout being a common experience for graduate students in medical school (Amir, Kumari, Olivetta, & Mansoor, 2018; Kroska et al., 2017), few studies have considered possible underlying risk or protective factors against burnout among graduate students. This study evaluated the possible roles EI and spirituality may play in student burnout in 76 doctoral clinical psychology students. All but 1 of the 76 students who participated reported experiencing at least some symptoms of burnout over the course of their studies, though most did not reach a critical risk level. However, students who scored higher on both measures of EI and spirituality reported lower than average levels of burnout symptoms. EI had a large effect size in predicting group membership, while spirituality had a moderate effect size in predicting group membership. The two groups differed significantly in degree of burnout symptoms. Other studies’ findings that spirituality was lower in more advanced cohorts than in lower cohorts (Eisele, 2016; Fisk et al., 2013) were not replicated in this study; rather scores were significantly higher for more advanced cohorts, raising the possibility that prior studies may have found cohort differences rather than developmental changes. This study’s findings suggest that graduate clinical training programs may wish to increase their focus on enhancing student EI and spirituality as a way to improve clinical training, decrease student burnout, and minimize deleterious student training experiences

A study on the hadroproduction of heavy resonances in ATLAS experiment at the LHC

This work is devoted to the study of the hadroproduction of heavy resonances and related topics. The study begins with a chapter that analyzes some experimental issues on heavy quarkonia production, pointing out the important role that the ATLAS detector at LHC can play in this regard. The main goal of chapter 2 is revising some theoretical aspects on bottomonia production, some relevant heavy quarkonia production models are visited, pointing out the most relevant features involved in this work. Later, chapter 3 describes the most relevant techniques used in order to generate the Upsilon(nS) family, as well as a description on the changes and new implementations in the original software of PYTHIA: In summary, all the tools that we needed when carrying out the bottomonia hadroproduction analysis. In chapter 4 we focused on the study of the information available on Upsilon production, basing our analysis of bottomonia inclusive production on the results from Run IB of the CDF collaboration : We analyze the differential Upsilon(nS) cross sections, extracting some relevant NRQCD matrix elements, paying attention to the problem concerning the factorization of the cross section, etc. In chapter 5 we make some predictions on bottomonium hadroproduction at the forthcoming LHC energies and kinematic conditions: We show the expected differential and integrated cross section for all Upsilon(nS) resonances, etc. In chapter 6 we present a proposal to probe gluon densities in the proton using Upsilon hadroproduction, within the framework of the colour-octet mechanism. Aside the proposal, we included predicted production rates, and details that arose during the development of the idea. Finally, in order to help the reading of this work, a lot of technical details have been separated from the main body of the text, gathering them in the appendices A-B-C

Prospects for probing the gluon density in protons using heavy quarkonium hadroproduction

We examine carefully bottomonia hadroproduction in proton colliders, especially focusing on the LHC, as a way of probing the gluon density in protons. To this end we develop some previous work, getting quantitative predictions and concluding that our proposal can be useful to perform consistency checks of the parameterization sets of different parton distribution functions.Comment: LaTeX, 14 pages, 6 EPS figure

Analyzing the Longevity of Sperm Within the Female Japanese Quail by Assessing Sperm Penetration of the Perivitelline Layer Under Optimal and Suboptimal Conditions.

After mating, birds have the ability to store semen within the female reproductive tract. The sperm storage tubules will store and subsequently release semen to travel up the oviduct. Sperm cells that make the trek up the oviduct have a chance to fertilize the ovum. These sperm cells will bind to the perivitelline layer of the ovum and hydrolyze a hole in the perivitelline layer, where it has the possibility to fertilize the female sex cell. Analyzing the number of penetration points on the perivitelline layer is an effective way to analyze reproductive efficiency. Many environmental factor has its effect on reproductive efficiency, however, only a few research trials have been done that analyze how environmental variables affect sperm penetration in itself. A population of 120 twelve week old random bred Japanese coturnix quail was separated into breeding ratios of three hens per cock making 30 pens with four birds in each. Treatments of optimal nutrition, suboptimal nutrition, and mild heat stress 75-80°F were utilized. These treatments were compared to a control group, where the males were not removed from the pen after 14 days. Males were left in the breeding pens for 14 days and then taken out, except for the control group where the males resided for the entire duration of the study. Sperm penetration assays were taken and analyzed every other day until no fertile eggs were laid. On every other consecutive day, eggs were collected and set to incubate until hatch. After hatch, percent hatchability was calculated. It was observed according to Davis’ Correlation coefficients that day of the trial has a substantial negative correlation on sperm penetration and percent hatch by (-0.65871) and (-0.5058) respectfully. Sperm penetration and percent hatch show a very strong positive correlation of (0.76404). This population of quail was observed to store semen in sufficient quantities to maintain at »30 sperm penetration points (SPP) for 3 days before dropping significantly in SPP (p \u3c 0.0001). Where this same population could lay hatchable eggs for 8 days before dropping in hatching percentage, (P \u3c 0.0024). Additionally, it was observed that proper nutrition had a more significantly greater effect by increasing SPP and slightly increasing percent hatch than the effects of heat stress. Overall, it appears that similar trials that observe the longevity of fertility could be used to model the environmental effects on SPP, transversely affecting hatchability

Including Gene Edited Sires in Genetic Evaluations

A simulation study investigated and provided potential solutions to practical issues that could arise from including gene-edited sires in routine genetic evaluations. Gene-editing is a technique for adding, deleting, or replacing nucleotides in the genome. Editing nucleotides controlling important socioeconomic traits (e.g., growth, carcass, disease susceptibility) is expected to improve rates of genetic gain. However, targeted alterations of the genome can affect the relationship among individuals and, consequently, introduce bias in Expected Progeny Differences. The current study illustrated that, indeed, Expected Progeny Differences for the progeny of edited sires were underestimated. Consequently, these animals would be less likely to be selected as parents for subsequent generations. Therefore, if edited sires are introduced into genetic evaluations, the statistical models used in the evaluation need to appropriately accommodate the changes among animals that the targeted gene edits create, and adjusting the kinship among animals is one way to do this. Without accounting for these targeted changes Expected Progeny Differences will be biased, and selection decisions could be made incorrectly

Locus coeruleus to basolateral amygdala noradrenergic projections promote anxiety-like behavior

Increased tonic activity of locus coeruleus noradrenergic (LC-NE) neurons induces anxiety-like and aversive behavior. While some information is known about the afferent circuitry that endogenously drives this neural activity and behavior, the downstream receptors and anatomical projections that mediate these acute risk aversive behavioral states via the LC-NE system remain unresolved. Here we use a combination of retrograde tracing, fast-scan cyclic voltammetry, electrophysiology, and in vivo optogenetics with localized pharmacology to identify neural substrates downstream of increased tonic LC-NE activity in mice. We demonstrate that photostimulation of LC-NE fibers in the BLA evokes norepinephrine release in the basolateral amygdala (BLA), alters BLA neuronal activity, conditions aversion, and increases anxiety-like behavior. Additionally, we report that β-adrenergic receptors mediate the anxiety-like phenotype of increased NE release in the BLA. These studies begin to illustrate how the complex efferent system of the LC-NE system selectively mediates behavior through distinct receptor and projection-selective mechanisms
