Coping During Hyperbaric Oxygen Therapy: Predictors and Intervention
The present research sought to understand patient experiences during Hyperbaric Oxygen Therapy (HBOT) by using 24 HBOT patients (17 men, 7 women) to examine the relationship between individual variables and anxiety, and providing One Session Exposure Therapy (OSET; Ăst, 1989) if necessary. Pre-HBOT participants completed the following measures: State-Trait Anxiety Inventory (STAI; Spielberger, 1983), Claustrophobia Questionnaire (CLQ; Radomsky, Rachman, Thordarson, McIsaac, & Teachman, 2001), Anxiety Sensitivity Index (ASI; Reiss, Peterson, Gursky, & McNally, 1986), and Treatment Credibility/Expectancy Questionnaire (CEQ; Devilly & Borkovec, 2000). State Anxiety was assessed pre-HBOT and at the tenth and last sessions. Findings suggest Dispositional Anxiety (STAI-Trait + ASI), Expectancy of symptom improvement (CEQ), and gender were significantly predictive of State Anxiety before and during HBOT. Limitations and directions for future research are discussed

Farmersâ spending on variable inputs tends to maximise crop yields, not profit
We estimate the marginal returns to spending on Crop Variable Inputs (CVI) (such as fertilizers and crop protection), to explore whether observed spending maximises physical or economic returns to farmers. Data are taken from the Farm Business Survey for 2004-2013, where gross margins and input spending are available, in over 10,300 crops of conventional winter wheat or oilseed rape in England and Wales. Marginal spending on CVIs generate financial returns significantly less than ÂŁ1 per marginal pound spent. This suggests that expenditure on CVIs exceeds an economic optimum that would maximise profit. However marginal physical products (crop yields) are positive, but small and significantly different from zero. This suggests that, on average, farmers approximately maximise yields. These results hold across a wide range of alternative economic models and two crop species. Similar results have been reported in estimations for Indian grain production and for maize in China. In practice, farmers are making decisions on input use in advance of having information on a variety of factors, including future yield, product quality and price, making it difficult to optimise input levels according to expected profit. Farmers may be consistently optimistic, prefer to avoid risk, or deliberately seek to maximise yields. Some farmers may put on the standard recommended application irrespective of input or expected output price. It is also possible that advice may sometimes aim to maximise yield, influenced by an incentive to encourage greater sales. Excessive input use both reduces private profits and is a cause of environmental damage. There are thus potential private as well as social benefits to be gained from optimising levels of input use
The Effect of School Funding on Standardized Test Scores
Most schools in America use standardized tests to determine how students do on average based on their peers and what they have been studying on school. These scores can also reflect a students comprehension on the material taught in class. The quality of the education provided can also be a factor that greatly influences a studentsâ performance on these standardized tests. The funding of a school is a major factor that influences the quality of education a school is able to provide. As a group, we analyzed data sets that analyzed the funding and standardized test scores of different schools in Illinois. In doing so, a better understanding between a schoolâs financial status and their standardized test scores was found, and this knowledge can be applied in future considerations about funding to improve the overall quality of education in schools in America
Many-body Majorana braiding without an exponential Hilbert space
Qubits built out of Majorana zero modes (MZMs) constitute the primary path
towards topologically protected quantum computing. Simulating the braiding
process of multiple MZMs corresponds to the quantum dynamics of a
superconducting many-body system. It is crucial to study the Majorana dynamics
both in the presence of all other quasiparticles and for reasonably large
system sizes. We present a method to calculate arbitrary many-body
wavefunctions as well as their expectation values, correlators and overlaps
from time evolved single-particle states of a superconductor, allowing for
significantly larger system sizes. We calculate the fidelity, transition
probabilities, and joint parities of Majorana pairs to track the quality of the
braiding process. We show how the braiding success depends on the speed of the
braid. Moreover, we demonstrate the topological CNOT two-qubit gate as an
example of two-qubit entanglement. Our work opens the path to test and analyze
the many theoretical implementations of Majorana qubits. Moreover, this method
can be used to study the dynamics of any non-interacting superconductor.Comment: v2: revised version, including the demonstration of CNOT gate via
