Abstract
Background: On the basis of our patient satisfaction survey, we initiated a quality improvement project at our institution to decrease waiting times for patients scheduled for chemotherapy. The mean waiting time until a patient started his or her session was 183.5 min. Our aim was to reduce the waiting time by 50% (&lt;90 min) over a 6-month period and to sustain it. Materials and Methods: We used a multidisciplinary approach to identify the root causes and contributing factors of prolonged waiting times for patients in the chemotherapy unit. We implemented three Plan–Do–Study–Act cycles over a 10-month period (February to December 2016). First, we redesigned the nursing triage process, treatment process, and nursing awareness programs. Second, we improved nursing documentation to ensure accurate tracking of patients who declined their appointment or were overbooked. Third, pharmacy forms and chemotherapy preparation were accomplished with the help of an electronic system. We implemented a department-wide standard of care to provide an early assessment of the patient on arrival, and we activated a specific chemotherapy clinic for patient booking and laboratory tests, which were supervised by a trained qualified oncologist. Results: Median time to chemotherapy administration was reduced by 40% in the first 3 months, 64% in 6 months, and 51% in 18 months. We checked every 2 weeks for sustained action and tracked the time from when the patient checked in until he or she received treatment, guided by electronic pharmacy confirmation. The mean waiting time continued to improve and no complaints were reported during the last 6 months of the post-intervention period. Conclusion: Our project resulted in a 40%–64% reduction in waiting times for patients in the chemotherapy unit over an 18-month period. Our plan is to sustain this improvement by continually monitoring waiting times and addressing any emerging issues.
Simultaneous Upper Triangular Forms for Commuting Operators in a Finite von Neumann Algebra

Published: May 2019

AbstractThe joint Brown measure and joint Haagerup–Schultz projections for tuples of commuting operators in a von Neumann algebra equipped with a faithful tracial state are investigated, and several natural properties are proved for these. It is shown that the support of the joint Brown measure is contained in the Taylor joint spectrum of the tuple, and also in the ostensibly smaller left Harte spectrum. A simultaneous upper triangularization result for finite commuting tuples is proved, and the joint Brown measure and joint Haagerup–Schultz projections are shown to behave well under the Arens multivariate holomorphic functional calculus of such a commuting tuple.

IntroductionOur previous study showed that naringin (NRG) protects cardiomyocytes against high glucose (HG)-induced injuries by inhibiting p38 mitogen-activated protein kinase (MAPK). Leptin induces hypertrophy in rat cardiomyocytes via p38/MAPK activation. The present study aimed to test the hypothesis that leptin-Janus kinase 2 (JAK2)/signal transducers and activators of transcription 3 (STAT3), which are responsible for leptin’s functions, are involved in HG-induced injuries and cardioprotective effects of NRG in cardiomyocytes.Material and methodsH9c2 cells were exposed to HG for 24 h to establish a cardiomyocyte injury model. Cells were pretreated with NRG and other drugs before exposure to HG. Protein expression was measured by western blot analysis. Cell viability was detected by Cell Counting Kit-8 assay. Apoptotic cells were assessed by Hoechst 33258 staining assay. Intracellular reactive oxygen species levels were determined by dichlorofluorescein diacetate staining. Mitochondrial membrane potential was evaluated using JC-1. An enzyme-linked immunosorbent assay was performed to determine the inflammatory cytokines.ResultsNRG significantly attenuated HG-induced increases in leptin and Ob-R expression. Pretreatment with either a leptin antagonist (LA) or NRG markedly ameliorated HG-induced elevation of phosphorylated (p)-JAK2 and p-STAT3, respectively. Pretreatment with NRG, LA, Ob-R antagonist, or AG490 clearly alleviated HG-induced injuries and inflammation.ConclusionsThis study provides new evidence of the NRG protective effects of H9c2 cells against HG-induced injuries possibly via modulation of the leptin-JAK2/STAT3 pathway.

BackgroundLexical research based on the assumption that all the main human characteristics are encoded in the natural language constitutes one of the alternative ways of developing a taxonomy of individual differences in psychology. The majority of studies to date, including Polish ones, have been restricted to the analysis of the adjective lexicon, which means their results are at risk of reduc-tionism. The aim of the presented research was to develop a classification of the complete Polish lexicon of person-descriptive terms (adjectives, participles, adverbs, nouns, and verbs).Participants and procedureWe analyzed 100,000 entries found in a universal dictionary of Polish and identified 27,813 terms used to describe human char-acteristics. The identified person-descriptive terms were classified by a team of 13 trained judges into 16 subcategories. The judges’ taxonomic decisions were tested for validity and reliability.ResultsPersonality (dispositional) descriptors (5,598) constitute 20.1% of the Polish lexicon of person-descriptors; this includes 1,641 adjectives and participles, 612 adverbs, 1,442 attribute-nouns, 1,029 type-nouns, and 916 verbs. The analysis of the semantic redundancy of terms representing different parts of speech but having the same common morpheme among dispositional de-scriptors revealed 1,979 morphemes with distinct meanings. Only 64% of these morphemes are represented by adjectives.ConclusionsAdjectives constitute the largest group of personality (dispositional) descriptors but do not account for the entire Polish person-ality lexicon. The results of the study are a point of departure for research into the specificity of the structure of personality de-scriptions in the Polish language using various linguistic categories and for a comprehensive study on the entire Polish personal-ity lexicon.

PurposeBeach handball is a physically demanding sport. The aim of the study was to establish the relationships between anthropometric characteristics and overarm ball speed, a key performance factor.MethodsOverall, 11 male players from the Spanish beach handball national team were recruited. Throw speed was assessed in 3 throw types: standing throw (ST), standing throw after two steps (RST), and jump throw with a run-up and self-spin (RSST). Pearson correlation was used to determine the correlation between variables. Magnitudes were evaluated qualitatively with magnitude-based inference, and the effects of anthropometric variables on the throw tests were analysed with stepwise multiple regression.ResultsMaximal throw speed was 25.64 ± 4.14 m ∙ s<sup>–1</sup> for ST, 23.71 ± 4.24 m ∙ s<sup>–1</sup> for RST, and 24.83 ± 5.49 m ∙ s<sup>–1</sup> for RSST. Large positive correlations were found between throw speed and middle, ring, and little finger lengths (P4 polygon) (<i>r</i> = 0.66 and 0.61 for ST and RSST, respectively). Very large (<i>r</i> = 0.77) and large (<i>r</i> = 0.68) correlations were observed between ST and RST, respectively, and elbow breadth. These results were likely positive for ST: P4 (76/24/0), elbow epicondyle distance (EED) (91/9/0); and for RST: EED (79/21/0); and possibly positive for RST: P4 (68/32/0). ST and RST were predicted by P4 in 44% and by combining P4 and finger span FS1 in 68%.ConclusionsST and RST ball speed in beach handball was related to specific hand/elbow anthropometric characteristics which can be easily measured.
Healthy and unhealthy eating amongst stressed students: considering the influence of mindfulness on eating choices and consumption

Published: May 2019

BackgroundAcademic stress is associated with (a) increased food intake and (b) choosing calorie-dense food choices in higher education students. In this research, mindfulness was used to alleviate academic stress and, in effect, promote healthier eating behaviours and decision-making.Participants and procedureNinety students were randomly allocated to either a mindfulness or a control condition. Both conditions ex-posed students to a stress-inducing task and levels of anxiety were recorded three times (i.e., prior to and after stress induction, and post-intervention) during the experiment. Chocolate and grapes were available to partici-pants after the experiment as a token of appreciation.ResultsIntention-to-treat analyses revealed that mindfulness had a non-significant effect on increasing consumption of healthy food, but assisted the decrease in consuming unhealthy food when compared to the control group. The main analyses revealed that when mindfulness alleviated stress (i.e., by using the anxiety measurements as a manipulation check), students consumed more healthy food and less unhealthy food.ConclusionsMindfulness appears to enable better decision making as regards healthy and unhealthy foods when mindful-ness meditation actually works. While the results appear positive, non-engagement with mindfulness medita-tion may necessitate the availability of other practices to reduce anxiety and stress. Clinical implications and the integration of health and wellbeing initiatives into universities are discussed.

PurposeThe aim of this volumetric study was to evaluate the relationship between brain atrophy quantification in multiple sclerosis (MS) patients and the progression of disability measured by neurological standardised tests.Material and methodsSeventeen patients (mean age 40.89 years) with clinically definite MS and 24 control subjects (mean age 38.45 years) were enrolled in the study. Brain examinations were performed on a 1.5T MR scanner. Automatic brain segmentation was done using FreeSurfer. Neurological disability was assessed in all patients in baseline and after a median follow-up of two years, using EDSS score evaluation.ResultsIn MS patients we found significantly (p < 0.05) higher atrophy rates in many brain areas compared with the control group. The white matter did not show any significant rate of volume loss in MS patients compared to healthy controls. Significant changes were found only in grey matter volume in MS subjects. At the follow-up evaluation after two years MS patients with deterioration in disability revealed significantly decreased cerebral volume in 14 grey matter areas at baseline magnetic resonance imaging (MRI) compared to MS subjects without disability progression.ConclusionsGrey matter atrophy is associated with the degree of disability in MS patients. Our results suggest that morphometric measurements of brain volume could be a promising non-invasive biomarker in assessing the volumetric changes in MS patients as related to disability progression in the course of the disease.

Abstract

The war in just war theory

Just war theory has an ancient pedigree. While the substantive norms and application of those norms have always been debated, the debate today is entirely polarized. So polarized, that there seems to be a ‘war’ raging in just war theory. On one side are representatives of Walzer’s conventional position and on the other side so-called revisionists as McMahan, Fabre, Rodin, and Frowe. This paper offers a critical analysis of that dichotomy. While most of the debate is focused on the substantive level (the norms itself), I focus here on the conceptual level (terminology and character of the positions) and meta-level (the underlying theoretical premises). My aim is threefold: to assist readers in understanding contemporary contributions to just war theory; to facilitate a truce between both camps by highlighting respective strengths and weaknesses and by exposing a certain division of labor; and to suggest improvements for both positions.
Synoptic-scale conditions and convection-resolving hindcast experiments of a cold-season derecho on 3 January 2014 in western Europe
Authors: Mathias Luca , Ludwig Patrick , Pinto Joaquim G. 
Published: May 2019

Abstract. A major linear mesoscale convective system caused severe weather over
northern France, Belgium, the Netherlands and northwestern Germany on
3 January 2014. The storm was classified as a cold-season derecho with
widespread wind gusts exceeding 25 m s−1. While such derechos
occasionally develop along cold fronts of extratropical cyclones, this
system formed in a postfrontal air mass along a baroclinic surface pressure
trough and was favoured by a strong large-scale air ascent induced by an
intense mid-level jet. The lower-tropospheric environment was characterised
by weak latent instability and strong vertical wind shear. Given the poor
operational forecast of the storm, we analyse the role of initial and lateral
boundary conditions to the storm's development by performing
convection-resolving limited-area simulations with operational analysis and
reanalysis datasets. The storm is best represented in simulations with high
temporally and spatially resolved initial and lateral boundary conditions
derived from ERA5, which provide the most realistic development of the
essential surface pressure trough. Moreover, simulations at
convection-resolving resolution enable a better representation of the
observed derecho intensity. This case study is testimony to the usefulness of
ensembles of convection-resolving simulations in overcoming the current
shortcomings of forecasting cold-season convective storms, particularly for
cases not associated with a cold front.
Qualitative yaw stability analysis of free-yawing downwind turbines
Authors: Wanke Gesine , Hansen Morten Hartvig , Larsen Torben Juul 
Published: May 2019

Abstract. This article qualitatively shows the yaw stability of a free-yawing downwind turbine and the ability of the turbine to align passively with the wind direction using a model with 2 degrees of freedom. An existing model of a Suzlon S111 upwind 2.1 MW turbine is converted into a downwind configuration with a 5∘ tilt and a 3.5∘ downwind cone angle. The analysis shows
that the static tilt angle causes a wind-speed-dependent yaw misalignment of up to −19∘ due to the projection of the torque onto the yaw bearing and the skewed aerodynamic forces caused by wind speed projection. With increased cone angles, the yaw stiffness can be increased for better yaw alignment and the stabilization of the free-yaw motion. The shaft length
influences the yaw alignment only for high wind speeds and cannot
significantly contribute to the damping of the free-yaw mode within the
investigated range. Asymmetric flapwise blade flexibility is seen to
significantly decrease the damping of the free-yaw mode, leading to
instability at wind speeds higher than 19 m s−1. It is shown that this
additional degree of freedom is needed to predict the qualitative yaw
behaviour of a free-yawing downwind wind turbine.
The effects of L1 AP-initial boundary tones and laryngeal features in Korean adaptation of Japanese plosives followed by a H or L vowel
Authors: Kim Hyunsoon 
Published: May 2019

The present study explores the magnitude of tonal effects and segmental voicing contrast in Korean categorization of Japanese plosives followed by a H or L vowel by conducting a perception experiment in which one hundred sixty native speakers of Seoul and Kyungsang Korean – eighty in each group (40 male and 40 female) – participated. The results have shown that, no matter whether they command a pitch-accent Kyungsang Korean or Seoul Korean which has no lexical pitch-accent, our subjects mostly categorized word-initial Japanese voiceless plosives as aspirated with the significant effect of H and word-medial voiceless plosives as either aspirated or fortis with no H/L effect. Their categorization of word-medial Japanese voiced plosives as lenis is not significantly affected by the H and L tonal difference, either, regardless of dialect differences. In their categorization of word-initial Japanese voiced plosives as lenis, however, the Seoul subjects favored L, and the Kyungsang subjects H.From the results, we propose that the Korean prosodic unit of Accentual Phrase (AP) and laryngeal features interact in the Seoul subjects’ categorization of word-initial Japanese plosives, such that the H/L tonal distinction is made in AP-initial position as enhancement with VOT primarily parsed for cues to the feature [±spread glottis]. As for their categorization of word-medial Japanese plosives with no tonal effect, we propose that closure duration is parsed for cues to the other feature [±tense]. The same proposal is made for the Kyungsang subjects’ categorization except for the H effect in word-initial Japanese voiced plosives.
What Perceivers Know About Their Own Affordance Perception: Post Hoc Evaluations of Perceptual Processes Do Not Relate to Accuracy
Authors: Thomas Brandon J. , Gill Devin M. , Pointon Grant , Creem-Regehr Sarah H. 
Published: May 2019

Abstract
In 2 studies, we sought to investigate participants’ awareness of their own cognitive process when perceiving affordances (i.e., action capabilities) and whether their evaluations of this process relate to affordance perception accuracy. In Study 1, we combined data from 8 experiments and created a coding scheme designed to capture the unique features of different affordance perception theories within these post hoc evaluations. We then tested whether the perceptual process that participants reported was related to the accuracy of their judgments. We found that evaluations were distributed fairly evenly across the themes. We also found no relationship between the evaluations and accuracy. In Study 2, we conducted an experiment that specifically addressed our hypotheses about awareness and affordance perception accuracy, while controlling for confounds in Study 1. The greater detail participants gave about their cognitive strategy produced reports that largely did not relate to affordance perception theories. Participants used one of a few strategies aimed at estimating their body dimensions. Our results suggest that awareness of the perceptual process has no influence on the accuracy of affordance perception. It is likely that subjective reports of affordance perceptual process, though clear to the perceiver, are not related to the process itself.
Can Cognitive Training Improve Shoot/Don’t-Shoot Performance? Evidence from Live Fire Exercises
Authors: Hamilton Joseph A. , Lambert Gary , Suss Joel , Biggs Adam T. 
Published: May 2019

Abstract
Police, security, and military personnel have—at most—seconds to make a shoot/don’t-shoot decision despite the life-or-death consequences of their actions. Recent research suggests that shoot/don’t-shoot errors (e.g., commission errors of shooting at nonhostile or unarmed civilians) can be linked to specific cognitive abilities, and these errors could be reduced through targeted cognitive training. However, these studies were conducted with untrained personnel, conducted with simulated weapons, or conducted with untrained personnel using simulated weapons. Before integrating cognitive training into real-world police and military firearm training, there should be evidence that training benefits also apply to trained shooters using live weapons and live ammunition. Here we assessed differences following cognitive training for trained law enforcement officers who performed pretraining and posttraining shooting tasks with live ammunition and their service-issued weapons. Our findings provide further support that targeted cognitive interventions can significantly improve firearm safety and efficacy for armed professionals.
Social Dominance Orientation Moderates the Effects of Socioeconomic Status on Well-Being
Authors: Whitt Cassie M. , Gore Jonathan S. , Jiang Tao 
Published: May 2019

Abstract
In the current study we argue that social dominance orientation (SDO) has a moderating effect on the relationship between regional inequalities in socioeconomic status (SES) and subjective well-being (SWB). Specifically, we predicted that individuals high in SDO, from high-SES regions of the United States, would have higher levels of well-being than those from low-SES regions of the United States. This hypothesis was tested by administering a series of self-report measures of SDO, SES, and SWB to a sample of undergraduate psychology students (n = 409). The data were analyzed with hierarchical linear modeling software to explore the relationships between these variables. The results were consistent with the initial hypothesis: Participants in high-SES regions (i.e., wealthier and more educated), who also identified as high in SDO, possessed higher levels of well-being than the participants from low-SES regions. Implications of such regional inequalities are discussed.

Abstract
“True!—nervous—very, very dreadfully nervous I had been and am.... The disease had sharpened my senses—not destroyed—not dulled them. Above all was the sense of hearing acute. I heard all things in the heaven and in the earth. I heard many things in hell.... Oh God! what could I do? I foamed—I raved—I swore! It grew louder—louder— louder! And still the men chatted pleasantly, and smiled. Was it possible they heard not? Almighty God!—no, no! They heard!—they suspected!—they knew!—they were making a mockery of my horror!... But anything was better than this agony! Anything was more tolerable than this derision! I could bear those hypocritical smiles no longer! I felt that I must scream or die! and now—again!—hark! louder! louder! louder! louder! “Villains!” I shrieked, “dissemble no more! I admit the deed!—tear up the planks! here, here!—It is the beating of his hideous heart!” Poe (1843)
