description: Osteoarthritis (OA) is the most common type of arthritis and a significant cause of disability worldwide. With an aging population in Canada, the prevalence and burden of OA is expected to increase. Knee OA is the most common form of OA, comprising upwards of 30% of cases. Early-stage OA can be difficult to diagnose, as often times pain and radiographical evidence do not align; however, abnormal subchondral bone remodelling has been considered to have an important role in OA pathogenesis, and some propose that it could offer a target for OA treatment. Clinically, measures of bone remodelling have been performed on iliac crest bone biopsies that are invasive and do not capture local changes. Recently, high resolution peripheral quantitative computed tomography (HR-pQCT) has been utilized in several different ways to analyse bone dynamics, or how the bone changes over time. These measurements are sensitive to several factors such as noise and motion but have yet to be validated in humans. The purpose of this study was to determine whether HR-pQCT can be used to measure longitudinal bone remodelling at the knee in humans with knee OA. Longitudinal bone remodelling results were compared to same-day rescan images to conduct a repeatability analysis. There were no significant differences between longitudinal and rescan results for bone formation (p = 0.47), bone resorption (p = 0.12), or net bone remodelling (p = 0.748). Additionally, the least detectable changes measured were 10.88% for bone formation, 10.53% for bone resorption, and 4.05% for net bone remodelling. These results indicate that with the current imaging procedures, there is too much error in the scans and processing pipeline to measure bone remodelling longitudinally in-vivo in the knee.

description: In this work we extend the first order formalism for cosmological models that present an interaction between a fermionic and a scalar field. Cosmological exact solutions describing universes filled with interacting dark energy and dark matter have been obtained. Viable cosmological solutions with an early period of decelerated expansion followed by late acceleration have been found, notably one which presents a dark matter component dominating in the past and a dark energy component dominating in the future. In another one, the dark energy alone is the responsible for both periods, similar to a Chaplygin gas case. Exclusively accelerating solutions have also been obtained.

description: Within AdS/CFT, we establish a general procedure for obtaining the leading singularity of two-point correlators involving operator insertions at different times. The procedure obtained is applied to operators dual to a scalar field which satisfies Dirichlet boundary conditions on an arbitrary time-like surface in the bulk. We determine how the Dirichlet boundary conditions influence the singularity structure of the field theory correlation functions. New singularities appear at boundary points connected by null geodesics bouncing between the Dirichlet surface and the boundary. We propose that their appearance can be interpreted as due to a non-local double trace deformation of the dual field theory, in which the two insertions of the operator are separated in time. The procedure developed in this paper provides a technical tool which may prove useful in view of describing holographic thermalization using gravitational collapse in AdS space.

Utilizzando diversi concetti della critica letteraria e della psicanalisi (dalle idee di M. L. Gasparov sui due approcci alla letteratura, filosofico e filologico, all’immagine di S. Frank che paragona il subconscio umano a una profonda «miniera», dal concetto di «acte gratuit» di W. H. Auden a quello di «epifania» di J. Joyce e U. Eco) e soffermandosi sull’esempio dell’episodio di Guerra e pace di Pierre a Borodino, l’autrice mostra come lo scrittore sia capace di dotare i personaggi dei suoi grandi romanzi tanto di una psicologia della profondità, quanto di una psicologia dell’altezza.

Subjects: subject: power system planning
subject: coordinated generation and transmission expansion planning
subject: generation and transmission cooptimization
subject: Engineering--Electronics and Electrical

description: Due to the depletion of conventional energy and environmental concerns, the trend toward increasing integration of renewable energy resources brings new challenges to power system planning and operation. The fluctuation of renewable energy resources is the main concern of system planners for their efficient deployment. Incorporating a more precise and detailed model of system constraints is inevitable to deal with these resources' intermittent and volatile nature. However, due to the various aspects and computation complexity of the capacity expansion problem, it is vital to have a thorough understanding of the most affecting constraints on the system planning. The unique characteristics of power systems, along with the integration of renewable energy resources and modern technologies such as energy storage, require developing a profound model for planning future infrastructure based on the available data. The primary objective of this research is to investigate and evaluate various aspects of power systems and develop a comprehensive capacity expansion model utilizing linear optimization techniques. The thesis includes the development of a data set for long-term planning purposes, a co-optimization expansion planning (CEP) model for identifying optimal transmission and generation expansion, modeling of storage technology and reserves, and reducing the network size to ensure model tractability. The framework was designed to facilitate the seamless integration of renewable energy sources and improve the performance of the whole power system, ensuring a smooth transition towards a high-renewable energy future. This tool intends to provide system planners and stakeholders in the generation and transmission sectors insights into future realizations of high-renewable power systems. The model can also be used as a benchmark for future planning studies and adjusted for any possible future assumptions.

description: A scheme for detection of abnormality in molecular nano-networks is proposed. This is motivated by the fact that early diagnosis, classification and detection of diseases such as cancer play a crucial role in their successful treatment. The proposed nano-abnormality detection scheme (NADS) comprises of a two-tier network of sensor nano-machines (SNMs) in the first tier and a data gathering node (DGN) at the sink. The SNMs detect the presence of competitor cells as abnormality that is captured by variations in parameters of a nano-communications channel. In the second step, the SNMs transmit micro-scale messages over a noisy micro communications channel (MCC) to the DGN, where a decision is made upon fusing the received signals. The detection performance of each SNM is analyzed by setting up a Neyman-Pearson test. Next, taking into account the effect of the MCC, the overall performance of the proposed NADS is quantified in terms of probabilities of misdetection and false alarm. A design problem is formulated, when the optimized concentration of SNMs in a sample is obtained for a high probability of detection and a limited probability of false alarm.

description: In questo studio ricostruiamo la storia di un racconto poco noto di Lev Tolstoj, Che cosa fa vivere gli uomini? (1881). In quest’opera Tolstoj volle rappresentare alcuni elementi chiave della sua nuova visione etico-religiosa maturata nel corso degli anni ’70 dell’Ottocento. Lo scrittore, inoltre, si impegnò nel distribuirla tra i ceti popolari urbani e nelle campagne e, grazie ad un’efficace opera di diffusione, l’opera fu letta da milioni di lettori popolari. Nell’articolo analizziamo da una parte le strategie narrative ed editoriali messe in gioco da Tolstoj nel suo racconto per conquistare i nuovi lettori; dall’altra, le tattiche di appropriazione, di adattamento e di trasformazione del testo tolstoiano da parte dei suoi lettori popolari.

Varying coefficient regression modeling by adaptive weights smoothing

description: The adaptive weights smoothing (AWS) procedure was introduced in Polzehl and Spokoiny (2000) in the context of image denoising. The procedure has some remarkable properties like preservation of edges and contrast, and (in some sense) optimal reduction of noise. The procedure is also fully adaptive and dimension free. Simulations with artificial images show that AWS is superior to classical smoothing techniques especially when the underlying image function is discontinuous and can be well approximated by a piecewise constant function. However, the latter assumption can be rather restrictive for a number of potential applications. Here the AWS method is generalized to the case of an arbitrary local linear parametric structure. We also establish some important results about properties of the AWS procedure including the so called "propagation condition" and spatial adaptivity. The performance of the procedure is illustrated by examples for local polynomial regression in univariate and bivariate situations.
Genetic analysis of the role of cellulose in Arabidopsis seed coat development and mucilage adherence
Creators: name: Griffiths, Jonathan Stewart
Publisher: name: University of British Columbia
Year: 2013

description: Primary plant cell walls are comprised largely of the polysaccharides cellulose, hemicellulose, and pectins, and can also contain up to 10% protein. These cell wall components interact non-covalently and covalently to form a functional cell wall. Interactions between cellulose and pectins are poorly understood, and are the focus of this research. Arabidopsis seed coat epidermal cells produce three distinct types of cell walls: an outer primary wall; mucilage, a specialized wall composed primarily of pectins; and a rigid columella. When seeds are hydrated, mucilage expands rapidly, breaking the outer wall, to form a mucilage halo that surrounds and remains adherent to the seed. The columella appears to be composed primarily of cellulose, and is therefore an excellent model for investigating cellulose biosynthesis. Cell wall biosynthesis and polysaccharide interactions were examined during seed coat development and in mucilage adherence to better understand cell wall assembly and function. Cellulose is synthesized by the CELLULOSE SYNTHASE A (CESA) family of glucosyltransferases. It has been proposed that at least three different CESAs are required to form a functional Cellulose Synthase Complex (CSC). I investigated the contribution of CESA2, CESA5 and CESA9 in cellulose biosynthesis during seed coat development. Based on seed coat epidermal cell morphology and cellulose quantification, all three CESAs have non-redundant roles in secondary wall biosynthesis, while CESA5 specifically functions in mucilage biosynthesis. CESA3 is expressed in the seed coat during mucilage biosynthesis and missense mutations in CESA3, isoxaben resistant 1 (ixr1-1 and ixr1-2), result in altered mucilage structure and pectin distribution, and reduced cellulose amounts in seeds. The mechanism of mucilage adherence was examined by comparing two loss of function mutants that disrupt adherence, cesa5-1 and sos5-2. SOS5 encodes an arabinogalactan protein hypothesized to influence adherence through CESA5. However, the phenotype of each single mutant differs and a cesa5 sos5 double mutant has an enhanced phenotype. Therefore, it is unlikely that SOS5 promotes mucilage adherence through CESA5. SOS5 may influence mucilage structure through galactans, as it is required for the proper function of the !- galactosidase, MUM2. This demonstrates a role for AGPs in galactan metabolism and cell wall polysaccharide interactions.
Linear Variance Bounds for Particle Approximations of Time-Homogeneous Feynman-Kac Formulae

description: This article establishes sufficient conditions for a linear-in-time bound on the non-asymptotic variance of particle approximations of time-homogeneous Feynman-Kac formulae. These formulae appear in a wide variety of applications including option pricing in finance and risk sensitive control in engineering. In direct Monte Carlo approximation of these formulae, the non-asymptotic variance typically increases at an exponential rate in the time parameter. It is shown that a linear bound holds when a non-negative kernel, defined by the logarithmic potential function and Markov kernel which specify the Feynman-Kac model, satisfies a type of multiplicative drift condition and other regularity assumptions. Examples illustrate that these conditions are general and flexible enough to accommodate two rather extreme cases, which can occur in the context of a non-compact state space: 1) when the potential function is bounded above, not bounded below and the Markov kernel is not ergodic; and 2) when the potential function is not bounded above, but the Markov kernel itself satisfies a multiplicative drift condition.

description: Land use modifications and climate change are two of the major factors behind global biodiversity losses. The specific impacts and long-term implications of these changes have yet to be understood for many species. Bumble bees (Bombus sp.) are an important group of pollinators, especially in temperate and montane regions where they are relatively abundant. They are also facing global declines and range shifts. In this thesis I pose several questions investigating the relationship between bumble bees and mountain landscapes. I first ask whether bumble bee abundance and species richness are positively or negatively associated with measures of landscape fragmentation. I then demonstrate patterns of genetic and phenotypic diversity and differentiation in the high elevation taxa Bombus lapponicus sylvicola and assess hypotheses about mechanisms that could be causing the differentiation I observe. Lastly, I test whether gene flow in four bumble bee taxa has been restricted between habitats of differing elevations. To answer these questions, I sampled 22 species of bumble bees from 69 sites across a 40,000 km2 geographic range, where sites were selected to minimize correlations between variables of interest. I extracted DNA from 745 individuals of four different taxa, and used SNPs derived from ddRAD libraries to measure genetic diversity and gene flow. In this thesis I report higher abundance and species richness of bumble bees in locations where surrounding land cover has higher levels of complementation between nesting and foraging habitats, but that abundance and species richness decrease with other measures of fragmentation. I describe a new cryptic subspecies of B. sylvicola based on genetic and phenotypic diversity, and present evidence that it may have differentiated under conditions of gene flow based on adaptation to cold minimum temperatures. Finally, I present evidence that high elevation taxa appear to be able to exchange genes freely across elevations, while taxa associated with lower elevations display patterns of reduced gene flow across elevations. These findings have important implications for the conservation of montane bumble bee species and provide several avenues for future study and investigation.

description: Un percorso di evoluzione interessa la letteratura etnica americana nei primi decenni del Ventesimo secolo. A una prima generazione che si rifà a schemi narrativi e ideologici presi a prestito dalla letteratura mainstream, succede una seconda generazione che guarda con interesse alla sperimentazione modernista e vuole portare alla luce aspetti problematici legati ai cambiamenti sociali provocati dall’immigrazione di massa. Nell’ambito della letteratura degli ebrei americani, l’analisi parallela dei romanzi The Rise of David Levinsky di Abraham Cahan, rappresentante del primo gruppo, e Jews Without Money di Michael Gold, appartenente al secondo, illustra le differenze di ordine strutturale e ideologico tra i due momenti. Il testo di Cahan, riscrittura polemica della forma rags to riches, propone un percorso narrativo incentrato sulla costruzione dell’individuo e sul tentativo di assimilazione all’ordine dominante, mentre il romanzo di Gold propone una segmentazione del punto di vista che trasforma il narratore in un testimone passivo delle vicende di altri personaggi, fornendo una prospettiva collettiva rappresentativa dei destini della comunità.

Identifying the Role of Mediators and Moderators on the Relationship between Early Traumatic Experiences and Problematic Alcohol Use: A Systematic Review and Longitudinal Study

description: Abstract Introduction: Despite a robust association between early traumatic experiences (ETEs) and problematic alcohol use, there is a dearth of longitudinal studies that have directly investigated this relationship in adolescents. Furthermore, previous studies have neglected the effect of important mediating and moderating variables. The current project aims to bridge these gaps and expand the literature on the trauma-addiction link using two distinct studies. Methods: Study 1 consisted of a systematic review that investigated the relationship between ETEs and problematic alcohol use using longitudinal studies where temporality was established. Study 2 employed a longitudinal dataset to investigate the relationship between ETEs and problematic alcohol use in adolescents, with a focus on mediating (externalizing behaviours and internalizing behaviours) and moderating (sex) effects. The data was collected over the course of 5-years via questionnaires and in-person interviews and was analyzed using latent growth curve models. Results: In Study 1, six of the nine prospective studies demonstrated a significant positive relationship between ETEs and problematic alcohol use. In Study 2, the first model showed that higher trauma severity was significantly associated with greater problematic alcohol use severity at baseline. Further, growth in trauma severity was associated with significant growth in problematic alcohol use severity over time. The second model indicated there was a positive relationship between trauma and problematic alcohol use severity at baseline for both males and females, but that this relationship was significantly stronger in females. The final mediation model showed that internalizing and externalizing behaviours mediated the relationship between trauma and problematic alcohol use severity at baseline and over time. Conclusion: The results from these studies advance our understanding of the relationship between ETEs and the development of alcohol use problems later in life. Study 1 lends evidence to the notion that ETEs are a risk factor for problematic alcohol use. Study 2 showed that internalizing and externalizing behaviours mediate the relationship between ETEs and problematic alcohol use, making these behaviours a good target in treatment for trauma-exposed youth.

description: We study Higgs inflation in the context of generalized G-inflation, i.e. the most general single-field inflation model with second-order field equations. The four variants of Higgs inflation proposed so far in the literature can be accommodated at one time in our framework. We also propose yet another class of Higgs inflation, the running Einstein inflation model, that can naturally arise from the generalized G-inflation framework. As a result, five Higgs inflation models in all should be discussed on an equal footing. Concise formulas for primordial fluctuations in these generalized Higgs inflation models are provided, which will be helpful to determine which model is favored from the future experiments and observations such as the Large Hadron Collider and the Planck satellite.

description: The pandemic had a disruptive impact on teaching and learning in higher education. For many, the transition to online learning presented enormous challenges, individually and collectively. Many of us sought immediate strategies to support student learning and success in an online context. We experienced many successes and failures along the way. This Guide provides an inspiring collection of scholarly reflections and approaches to supporting meaningful course learning opportunities for students and postsecondary educators, in online environments. The guide contains nine chapters contributed by members of the Teaching Academy from across disciplines involved in undergraduate and/or graduate instruction, writing solo or with collaborators, to highlight an aspect of their teaching that leverages the online environment to enhance student learning. Each of these chapters offers sage, pragmatic descriptions of course contexts, design considerations, and implementation, for online assessments (Chapter 1, 4), for innovative learning activities (Chapter 2, 6), for flexible course design (Chapter 5, 7), for engaging large classes (Chapter 8), for facilitating group work (Chapter 9), and for intentionally addressing the need for students to flourish (Chapter 3). Importantly, for the reader, each chapter shares the wisdom of practice of the author/s, discussing implications of use and giving concrete recommendations for those who are thinking of applying similar strategies.

Fornite queste definizioni – che assumono tanta più rilevanza se si considera la notevole diffusione che esse hanno avuto nell’ambito degli studi narratologici – l’attenzione si sposta sulle conseguenze di carattere epistemologico che una tale proposta implica nella configurazione degli studi narrativi e, in particolare, in merito all’adattamento, che non può essere più di tipo realistico, rispetto al proprio oggetto di studio. A conclusione del lavoro, Sternberg specifica la propria proposta: essendo la narratività – ecco, in sintesi, l’argomento finale – il procedimento che qualifica il discorso narrativo attraverso criteri anti-rappresentazionali, transmediali e dialogici, l’indagine critica sulla narrazione deve porsi co- me obiettivo primario quello di analizzare i meccanismi cognitivi e le strategie discorsive che so- no alla base dell’interazione dialogica tra lettore e opera (in modo da ancorare le proprie premes- se sulla specificità stessa del genere narrativo) e, secondariamente, di comprendere come tale procedimento invariante entri in relazione e modifichi, «narrativizzando», i fattori variabili dell’universo narrativo (al fine di stabilire una disposizione gerarchica tra i diversi fattori narrativi).

description: Differently from correlation of classical systems, entanglement of quantum systems cannot be distributed at will - if one system A is maximally entangled with another system B, it cannot be entangled at all to a third system C. This concept, known as the monogamy of entanglement, manifests when the entanglement of A with a pair BC, can be divided as contributions of entanglement between A and B and A and C, plus a term τ_{ABC} involving genuine tripartite entanglement and so expected to be always positive. A very important measure in Quantum Information Theory, the Entanglement of Formation (EOF), fails to satisfy this last requirement. Here we present the reasons for that and show a set of conditions that an arbitrary pure tripartite state must satisfy for EOF to become a monogamous measure, ie, for τ_{ABC} \ge 0. The relation derived is connected to the discrepancy between quantum and classical correlations, being τ_{ABC} negative whenever the quantum correlation prevails over the classical one. This result is employed to elucidate features of the distribution of entanglement during a dynamical evolution. It also helps to relate all monogamous instances of EOF to the Squashed Entanglement, an always monogamous entanglement measure.

description: We introduce a general non-parametric independence test between right-censored survival times and covariates, which may be multivariate. Our test statistic has a dual interpretation, first in terms of the supremum of a potentially infinite collection of weight-indexed log-rank tests, with weight functions belonging to a reproducing kernel Hilbert space (RKHS) of functions; and second, as the norm of the difference of embeddings of certain finite measures into the RKHS, similar to the Hilbert-Schmidt Independence Criterion (HSIC) test-statistic. We study the asymptotic properties of the test, finding sufficient conditions to ensure our test correctly rejects the null hypothesis under any alternative. The test statistic can be computed straightforwardly, and the rejection threshold is obtained via an asymptotically consistent Wild Bootstrap procedure. Extensive investigations on both simulated and real data suggest that our testing procedure generally performs better than competing approaches in detecting complex non-linear dependence.

Shared memory algorithms

description: Bounded timestamps [9, 19 ] allow a temporal ordering of events in executions of concurrent algorithms. They are a fundamental and well studied building block used in many shared memory algorithms. A concurrent timestamp system keeps track of 𝑚 timestamps, which is usually greater or equal to the number of processes in the system, 𝑛. A process may, at any point, obtain a new timestamp, and later determine a total order of all process’s most recent timestamps. Known timestamp algorithms do not scale well in the number of processes. Getting a new timestamp takes at least a linear number of steps, and a lower bound by Israeli and Li [ 19 ] implies that each timestamp needs to be represented by at least Ω(𝑚) bits. We introduce a slightly different semantics for timestamping, where there is no fixed timestamp value associated with an event. A process can execute operation updateTS() to update its latest timestamp, associating it with the (linearization) point of that operation, and is Earlier (𝑝,𝑞) to determine the temporal order of the latest updateTS() operations executed by processes 𝑝 and 𝑞. Since no static timestamp value is returned by update TS(), the lower bound of Israeli and Li does not apply. We present efficient linearizable and wait-free implementations of these methods using a single bounded fetch-and-add object and 𝑂 (𝑛²) bounded compare-and-swap objects, which are available on standard hardware. The step complexity of each method call is constant, and base objects need only store 𝑂 (log 𝑛) bits.

description: Motivated by thermodynamic considerations, we analyse the variation of the quantum mutual information on a unitary orbit of a bipartite system's state, with and without global constraints such as energy conservation. We solve the full optimisation problem for the smallest system of two qubits, and explore thoroughly the effect of unitary operations on the space of reduced-state spectra. We then provide applications of these ideas to physical processes within closed quantum systems, such as a generalized collision model approach to thermal equilibrium and a global Maxwell demon playing tricks on local observers. For higher dimensions, the maximization of correlations is relatively straightforward for equal-sized subsystems, however their minimisation displays non-trivial structures. We characterise a set of separable states in which the minimally correlated state resides: a collection of classically correlated states admitting a particular "Young tableau" form. Furthermore, a partial order exists on this set with respect to individual marginal entropies, and the presence of a "see-saw effect" for these entropies forces a finer analysis to determine the optimal tableau.

description: Low Impact Development (LID) aims to mitigate and prevent the negative impacts of urbanization on the hydrology and water quality of the natural water bodies. Bioretention systems are some of the most popular LID systems that offer various benefits, including reduction of peak runoff, attenuation of excess runoff volume, retention of various pollutants, as well as aesthetic and habitat benefits. This research provides a comprehensive investigation of bioretention performance using mesocosms and controlled runoff application. The research site for this project was constructed in the Town of Okotoks, Alberta, in 2016/2017. The site consists of 24 lined mesocosms that were designed to receive no natural runoff and were drained by pumping through a perforated standpipe. There were three different bioretention media and three different vegetation types. Among the media, there was a unique mix of clay-loam and wood chips, as an alternative to the conventional sand-based bioretention media. The mesocosms were analyzed for their hydrologic and water quality performance using 72 simulated runoff events over four growing seasons. The mesocosms with different media exhibited significant differences in water retention at the onset of the study period yet became increasingly similar over time, whereas the differences in vegetation impacts increased over time. The water quality analytes include Total Phosphorus (TP), Reactive Phosphorus (RP), Total nitrogen (TN), Nitrate-Nitrogen (NO¬¬3-N), and Total Organic Carbon (TOC). The research revealed significant leaching of nutrients and organics over four years. The leaching of nitrogen and organic compounds decreased over time, whereas phosphorus leaching persisted. This research also monitored the infiltration rate of the mesocosms, and an overall increasing trend in the infiltration rate was observed. Among the three media types, the clay-loam media had the highest infiltration rates, showing promise for future implementation. Soil respiration was measures as an indirect method of quantifying root activity, where the greatest respiration was associated with the clay-loam media. This research showcased the variability and changes in bioretention performance over time, as well as highlighted the role of the media and vegetation in various aspects of performance.

description: The estimation of variance-based importance measures (called Sobol' indices) of the input variables of a numerical model can require a large number of model evaluations. It turns to be unacceptable for high-dimensional model involving a large number of input variables (typically more than ten). Recently, Sobol and Kucherenko have proposed the Derivative-based Global Sensitivity Measures (DGSM), defined as the integral of the squared derivatives of the model output, showing that it can help to solve the problem of dimensionality in some cases. We provide a general inequality link between DGSM and total Sobol' indices for input variables belonging to the class of Boltzmann probability measures, thus extending the previous results of Sobol and Kucherenko for uniform and normal measures. The special case of log-concave measures is also described. This link provides a DGSM-based maximal bound for the total Sobol indices. Numerical tests show the performance of the bound and its usefulness in practice.

description: The aim of this research was to develop greater insight into the relationships between coaching efficacy, transformational leadership, emotional intelligence in addition to coach-athlete relationships. Due to the limited research of these variables in the field of sport psychology, one-hundred and forty-seven coaches associated with Hockey Calgary completed the Coaching Efficacy Scale (CES; Feltz et al., 1999), Multifactor Leadership Questionnaire (MLQ; Bass, 1998), Schutte’s Emotional Intelligence Scale (SEIS) (Schutte et al., 1998) and the Coach-Athlete Relationship Questionnaire (CART-Q; Jowett & Ntoumanis, 2004). Using Structural Equation Modeling (SEM) to examine the hypothetical mediational effect of coaching efficacy (CE) between emotional intelligence (EI) and transformational leadership (TFL). Additionally, coach-athlete relationships were examined to see how this measure correlated with EII, Ce, and TFL. Based on SEM, the final model had a good fit for the data, where coaching efficacy had a significant positive direct effect on transformational leadership, emotional intelligence, and coach-athlete relationships. A significant finding was that coaching efficacy partially mediated the relationship between emotional intelligence and transformational leadership. Pearson correlation analyses were also conducted and found that positive moderate correlations (r = 0.4-0.59) were found between most variables on the CES, MLQ, SEIS and CART-Q and negative weak correlations were found between the transactional leadership variables in the MLQ and variables of the CES, SEIS and CART-Q.
