An Examination Between High and Low Optimistic NCAA Division I Student-Athletes\u27 Perceptions of Preferred Leadership Behavior in Sport: A Qualitative Investigation

Numerous researchers have examined preferred sport leadership behaviors from both the coach and athlete perspectives (Beam, Serwatka, & Wilson, 2004; Chelladurai, & Carron, 1983; Freakley, Czech, Harris, & Burdette, 2012; Turman, 2013; Weinburg, & Gould, 2010). However, there is limited research in student-athlete personality dispositions and how those might influence student-athlete perceptions of preferred leadership behaviors. The purpose of the present study was to examine views of leadership in light of certain personality dispositions. This research examined the potential influence of optimism (Abramson, et al, 2000) on qualitative descriptions of preferred leadership behaviors using the Revised Leadership Scale for Sport (Zhang, & Jensen, 1998) to structure the interview questions. 106 NCAA Division I student-athletes in a southeastern university completed the Life Orientation Test-Revised (LOT-R), the results of which were split into three groups: low optimists, middle optimists, and high optimists. The low and high groups of student-athletes were considered for the qualitative interview. There were several similarities between the two groups regarding instructive behavior, feedback behavior, relatability, coach traits, and situational actions, but there are also several differences between the two groups in how the student-athletes prefer their coach to approach them. These differences are highlighted best in the category Reactive Behaviors with the high optimistic theme Encourages implying preference for a coach to focus on present emotions in order to attain future success while the low optimistic theme Reassures Athlete of Ability implies the preference for a coach to focus on past successes in order to attain success in the present. The category Coach Orientation (relationship- v results/task-focused) was much more convoluted than expected following past research. All four categories and emergent themes are described in full. The results reveal a deep difference in individual student-athlete perspective according to optimism levels and potential future research in discussed further

Editorial: Student-teacher relationship quality research: Past, present and future

More than 20 years have passed since the publication of Pianta (2001) on the quality of the teacher-student relationship. Since then, several attempts have been made to elaborate theoretically the concept of teacher-student relationship quality and to provide empirical evidence of the impact that good teacher-student relationship quality might have on academic achievement, student psychological adjustment, and classroom climate. The teacher has been recognized as a “psychological parent” and defined as a secure base and safe heaven, following attachment theory (Verschueren and Koomen, 2012, 2021; Prino et al., 2022; Spilt et al., 2022). Several studies have shown that a relationship with the teacher characterized by affection, closeness, and respect predicts more favorable developmental outcomes and better adjustment to the classroom context in any school setting (Roorda et al., 2011, 2017; Longobardi et al., 2019, 2021; Lin et al., 2022). However, after 20 years, we saw the need to synthesize the current literature on the topic of teacher-learner relationship quality and to promote a collection of studies that provide new insights, ideas, and reflections to advance the research field and overcome current limitations.In this Research Topic, 16 publications were collected from different parts of the world. The Research Topic includes two literature reviews, several empirical works, some of which aim to develop and validate instruments to measure the quality of the teacher-student relationship, and others to promote new knowledge about the effects and mechanisms of action of the quality of the teacher-learner relationship on the psychological development and adjustment processes of children and adolescents. In addition, the Research Topic includes a contribution on possible intervention strategies on the quality of teacher-student relationship

Word-level Symbolic Trajectory Evaluation

Symbolic trajectory evaluation (STE) is a model checking technique that has been successfully used to verify industrial designs. Existing implementations of STE, however, reason at the level of bits, allowing signals to take values in {0, 1, X}. This limits the amount of abstraction that can be achieved, and presents inherent limitations to scaling. The main contribution of this paper is to show how much more abstract lattices can be derived automatically from RTL descriptions, and how a model checker for the general theory of STE instantiated with such abstract lattices can be implemented in practice. This gives us the first practical word-level STE engine, called STEWord. Experiments on a set of designs similar to those used in industry show that STEWord scales better than word-level BMC and also bit-level STE.Comment: 19 pages, 3 figures, 2 tables, full version of paper in International Conference on Computer-Aided Verification (CAV) 201

Relationship Between Foveal Cone Structure and Visual Acuity Measured With Adaptive Optics Scanning Laser Ophthalmoscopy in Retinal Degeneration.

PurposeTo evaluate foveal function in patients with inherited retinal degenerations (IRD) by measuring visual acuity (VA) after correction of higher-order aberrations.MethodsAdaptive optics scanning laser ophthalmoscopy (AOSLO) was used to image cones in 4 healthy subjects and 15 patients with IRD. The 840-nm scanning laser delivered an "E" optotype to measure AOSLO-mediated VA (AOSLO-VA). Cone spacing was measured at the preferred retinal locus by two independent graders and the percentage of cones below the average density of 47 age-similar healthy subjects was computed. Cone spacing was correlated with best-corrected VA measured with the Early Treatment of Diabetic Retinopathy Study protocol (ETDRS-VA), AOSLO-VA, and foveal sensitivity.ResultsETDRS-VA significantly correlated with AOSLO-VA (ρ = 0.79, 95% confidence interval [CI] 0.5-0.9). Cone spacing correlated with AOSLO-VA (ρ = 0.54, 95% CI 0.02-0.7), and negatively correlated with ETDRS letters read (ρ = -0.64, 95% CI -0.8 to -0.2). AOSLO-VA remained ≥20/20 until cones decreased to 40.2% (CI 31.1-45.5) below normal. Similarly, ETDRS-VA remained ≥20/20 until cones were 42.0% (95% CI 36.5-46.1) below normal. Cone spacing z scores negatively correlated with foveal sensitivity (ρ = -0.79, 95% CI -0.9 to -0.4) and foveal sensitivity was ≥35 dB until cones were 43.1% (95% CI 39.3-46.6) below average.ConclusionsVA and foveal cone spacing were weakly correlated until cones were reduced by 40% to 43% below normal. The relationship suggests that VA is an insensitive measure of foveal cone survival; cone spacing may be a more sensitive measure of cone loss

Wilson ratio in Yb-substituted CeCoIn5

We have investigated the effect of Yb substitution on the Pauli limited, heavy fermion superconductor, CeCoIn$_5$. Yb acts as a non-magnetic divalent substituent for Ce throughout the entire doping range, equivalent to hole doping on the rare earth site. We found that the upper critical field in (Ce,Yb)CoIn$_5$ is Pauli limited, yet the reduced (H,T) phase diagram is insensitive to disorder, as expected in the purely orbitally limited case. We use the Pauli limiting field, the superconducting condensation energy and the electronic specific heat coefficient to determine the Wilson ratio ($R_{W}$), the ratio of the specific heat coefficient to the Pauli susceptibility in CeCoIn$_5$. The method is applicable to any Pauli limited superconductor in the clean limit.Comment: 5 pages, 1 table, 4 figure

Loss of Foveal Cone Structure Precedes Loss of Visual Acuity in Patients With Rod-Cone Degeneration.

PurposeTo assess the relationship between cone spacing and visual acuity in eyes with rod-cone degeneration (RCD) followed longitudinally.MethodsHigh-resolution images of the retina were obtained using adaptive optics scanning laser ophthalmoscopy from 13 eyes of nine RCD patients and 13 eyes of eight healthy subjects at two sessions separated by 10 or more months (mean 765 days, range 311-1935 days). Cone spacing Z-score measured as close as possible (average <0.25°) to the preferred retinal locus was compared with visual acuity (letters read on the Early Treatment of Diabetic Retinopathy Study [ETDRS] chart and logMAR) and foveal sensitivity.ResultsCone spacing was significantly correlated with ETDRS letters read (ρ = -0.47, 95%CI -0.67 to -0.24), logMAR (ρ = 0.46, 95%CI 0.24 to 0.66), and foveal sensitivity (ρ = -0.30, 95%CI -0.52 to -0.018). There was a small but significant increase in mean cone spacing Z-score during follow-up of +0.97 (95%CI 0.57 to 1.4) in RCD patients, but not in healthy eyes, and there was no significant change in any measure of visual acuity.ConclusionsCone spacing was correlated with visual acuity and foveal sensitivity. In RCD patients, cone spacing increased during follow-up, while visual acuity did not change significantly. Cone spacing Z-score may be a more sensitive measure of cone loss at the fovea than visual acuity in patients with RCD

Cone Spacing Correlates With Retinal Thickness and Microperimetry in Patients With Inherited Retinal Degenerations.

PurposeTo determine whether high-resolution retinal imaging measures of macular structure correlate with visual function over 36 months in retinal degeneration (RD) patients and normal subjects.MethodsTwenty-six eyes of 16 RD patients and 16 eyes of 8 normal subjects were studied at baseline; 15 eyes (14 RD) and 11 eyes (6 normal) were studied 36 months later. Adaptive Optics Scanning Laser Ophthalmoscopy (AOSLO) was used to identify regions of interest (ROIs) with unambiguous cones at baseline to measure cone spacing. AOSLO images were aligned with spectral-domain optical coherence tomography (SD-OCT) and fundus-guided microperimetry results to correlate structure and function at the ROIs. SD-OCT images were segmented to measure inner segment (IS) and outer segment (OS) thickness. Correlations between cone spacing, IS and OS thickness and sensitivity were assessed using Spearman correlation coefficient ρ with bootstrap analyses clustered by person.ResultsCone spacing (ρ = 0.57, P < 0.001) and macular sensitivity (ρ = 0.19, P = 0.14) were significantly correlated with eccentricity in patients. Controlling for eccentricity, cone spacing Z-scores were inversely correlated with IS (ρ = -0.29, P = 0.002) and OS thickness (ρ = -0.39, P < 0.001) in RD patients only, and with sensitivity in normal subjects (ρ = -0.22, P < 0.001) and RD patients (ρ = -0.38, P < 0.001). After 36 months, cone spacing increased (P < 0.001) and macular sensitivity decreased (P = 0.007) compared to baseline in RD patients.ConclusionsCone spacing increased and macular sensitivity declined significantly in RD patients over 36 months. High resolution images of cone structure correlated with retinal sensitivity, and may be appropriate outcome measures for clinical trials in RD
