Learning from experiences of peer support at an integrated youth service organization : a qualitative study
Creators: name: Devane, Courtney
Publisher: name: University of British Columbia
Year: 2023

description: Mental health challenges are the leading cause of disability in youth worldwide. In Canada, mental health challenges affect one in five youth by age 24. When youth activate mental health services, they reduce their likelihood of experiencing problems later in life, yet less than 20% of youth with mental health challenges are accessing these services. This gap is largely attributed to a lack of comprehensive, well-designed health care services to meet the needs of this age group effectively. Canada’s mental health strategy identifies peer support as an essential component of mental health services. However, the majority of peer support research has focused on adult populations. Largely missing from the literature is an understanding of peer support in a youth mental health context. The purpose of this research was to learn from experiences of peer support at an integrated youth services (IYS) organization in British Columbia (BC), Canada. This study utilized interpretive description methodology and a research community partnership model. Data were collected from IYS centers across BC in urban, rural, and Northern settings. Qualitative, semi-structured interviews were conducted and analyzed to examine how peer support is experienced by: youth peer support workers (YPSWs), service providers, and youth recipients of peer support. Findings are presented within each group of participants. A discussion of similarities and differences across groups illustrates key priorities to advance youth peer support in a meaningful way. Four recommendations to guide IYS organizations in strengthening their youth peer support services are provided: 1) Standardize YPSW hiring and onboarding processes across the IYS network; 2) Establish senior peer support roles and regional peer support practice leads; 3) Implement an evidence-based model of supervision for YPSWs; and 4) Increase the availability and accessibility of YPSWs across BC. Strategies to achieve each recommendation are discussed. As the need for mental health services for youth continues to rise, developing and implementing recovery-oriented and evidence-based interventions is crucial. This study aimed to generate new knowledge to optimize and scale peer support at IYS organizations and to guide broader policies for mental health services offered to youth and by youth in BC, and beyond.

description: In vielen Unternehmen werden Referenzmodelle genutzt, um Geschäftsprozesse zu verwalten und zu beschreiben. Dabei hat sich die adaptive Referenzmodellierung bewährt, um den Anpassungsaufwand für einzelne Anwendungsfälle und Prozesse gering zu halten. Mit Hilfe dieser können Referenzmodelle auf projektspezifische Ausprägungen beschränkt werden. Das Institute for Data and Process Science der Hochschule Landshut hat hierfür einen auf BPMN basierenden Modeler Namens ADAMO entwickelt, mit dem adaptive Referenzmodelle kollaborativ erstellt werden können.
Die Adaption des Referenzmodells basiert hierbei auf einer booleschen Termauswertung. Elementen werden hierbei Terme zugeordnet, welche Variablen beinhalten. Bei der Auswertung werden Evaluationswerte übergeben, mit denen die Termauswertung stattfindet. Elemente mit Term-Ergebnis 0 werden anschließend entfernt und Elemente mit Term-Ergebnis 1 bleiben bestehen.
Ziel dieser Arbeit ist die Umsetzung einer graduellen Verarbeitungslogik für den ADAMO-Modeler. Dieser graduelle Ansatz wird erforscht, da eine rein boolesche Vorgehensweise bei der Adaption in verschiedenen Anwendungsfällen nicht ausreichend differenzieren kann, ohne sich zu Lasten der Übersichtlichkeit in eine Mehrzahl verschiedener Unterfälle aufteilen zu müssen. Um den Nutzen eines graduellen Vorgehens für diese Fälle prüfen zu können, soll eine prototypische graduelle Termauswertungslogik konzipiert und implementiert werden. Dafür wurde der bisherige ADAMO-Modeler analysiert und boolesche und graduelle Logik recherchiert. Anschließend wurden auf Basis der Anforderungen des Institute for Data and Process Science sowie dem bisherigen ADAMO-Modeler Anforderungen an eine solche Logik und einer dazugehörigen Testumgebung erhoben, ein Umsetzungskonzept entwickelt und sowohl Logik als auch Testumgebung realisiert. Ergebnis der Arbeit ist ein funktionsfähiger Prototyp einer graduellen Termverarbeitungslogik sowie eine dazugehörige Testumgebung.
Duality between Wilson loops and gluon amplitudes

description: An intriguing new duality between planar MHV gluon amplitudes and light-like Wilson loops in N=4 super Yang-Mills is investigated. We extend previous checks of the duality by performing a two-loop calculation of the rectangular and pentagonal Wilson loop. Furthermore, we derive an all-order broken conformal Ward identity for the Wilson loops and analyse its consequences. Starting from six points, the Ward identity allows for an arbitrary function of conformal invariants to appear in the expression for the Wilson loop. We compute this function at six points and two loops and discuss its implications for the corresponding gluon amplitude. It is found that the duality disagrees with a conjecture for the gluon amplitudes by Bern et al. A recent calculation by Bern et al indeed shows that the latter conjecture breaks down at six gluons and at two loops. By doing a numerical comparison with their results we find that the duality between gluon amplitudes and Wilson loops is preserved. This review is based on the author's PhD thesis and includes developments until May 2008.

description: Purpose: This study evaluated the test-retest reliability of the Wingate Anaerobic Test (WAnT) performed on a Velotron electromagnetically-braked cycle ergometer (EE) for power-trained athletes and assessed whether a familiarization trial was necessary to achieve high test-retest reliability. Methods: Twenty-one male ice hockey players (age 23.5 ± 4.7 yrs, mass 86.3 ± 16.6 kg, height 180.9 ± 7.4 cm) from a collegiate club team (Club = 10) and a recreational league (Rec = 11) performed three, 30-sec WAnTs within 2 weeks, and with at least 24 hours between visits. Mean power, anaerobic capacity, peak power, anaerobic power, maximum RPM, and fatigue index were assessed. Resistance was 8.5% of the participant’s body weight. Results: The effect of time on power output was moderated (p < .001, ηp2 = .24) such that a significant increase was observed after a practice trial, but not between subsequent trials for the Club players; no practice effect was observed among Rec players. Extremely high reliability was found between trials after excluding the practice trial (ICC1,1 > .89). The Club players achieved higher outputs despite no significant differences in body size or age compared to the Rec League players. Conclusion: Ice hockey players performing the 30-sec WAnT on the Velotron EE had highly reliable data, and using a familiarization trial is recommended to increase reliability and achieve higher power outputs. Lastly, because WAnT results from EE and mechanically-braked ergometers cannot be compared, normative tables for EE results need to be created.

Ion-Acoustic Solitons in Bi-Ion Dusty Plasma

Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The propagation of ion-acoustic solitons in a warm dusty plasma containing two ion species is investigated theoretically. Using an approach based on the Korteveg-de-Vries equation, it is shown that the critical value of the negative ion density that separates the domains of existence of compressi- on and rarefaction solitons depends continuously on the dust density. A modified Korteveg-de Vries equation for the critical density is derived in the higher order of the expansion in the small parameter. It is found that the nonlinear coefficient of this equation is positive for any values of the dust density and the masses of positive and negative ions. For the case where the negative ion density is close to its critical value, a soliton solution is found that takes into account both the quadratic and cubic nonlinearities. The propagation of a solitary wave of arbitrary amplitude is investigated by the quasi-potential method. It is shown that the range of the dust densities around the critical value within which solitary waves with positive and negative potentials can exist simultaneously is relatively wide.

description: We present a multi-epoch (20 years baseline) kinematical investigation of HH52, 53, and 54 at optical and near-IR wavelengths, along with medium and high- resolution spectroscopic analyses, probing the kinematical and physical time variability conditions of the gas along the flows. By means of multi-epoch and multi-wavelength narrow-band images, we derived proper motions, tangential velocities, velocity and flux variability of the knots. Radial velocities and physical parameters of the gas were derived from spectroscopy. Finally, spatial velocities and inclination of the flows were obtained by combining both imaging and spectroscopy. The P.M. analysis reveals three distinct, partially overlapping outflows. In 20 years, about 60% of the knots show some degree of flux variability. Our set of observations apparently indicates acceleration and deceleration in a variety of knots along the jets. For about 20% of the knots, mostly coincident with working surfaces or interacting knots along the flows, a relevant variability in both flux and velocity is observed. We argue that both variabilities are related and that all or part of the kinetic energy lost by the interacting knots is successively radiated. The analysis indicates the presence of very light, ionised, and hot flows, impacting a denser medium. Several knots are deflected. At least for a couple of them (HH54 G and G0), the deflection originates from the collision of the two. For the more massive parts of the flow, the deflection is likely the result of the flow collision with a dense cloud or with clumps.

description: The origin and properties of the source of positrons annihilating in the Galactic Center is still a mystery. One of the criterion, which may discriminate between different mechanisms of positron production there, is the positron energy injection. Beacom and Yueksel (2006) suggested a method to estimate this energy from the ratio of the 511 keV line to the MeV in-flight annihilation fluxes. From the COMPTEL data they derived that the maximum injection energy of positron should be about several MeV that cut down significantly a class of models of positron origin in the GC assuming that positrons lose their energy by Coulomb collisions only. However, observations show that the strength of magnetic field in the GC is much higher than in other parts of the Galaxy, and it may range there from 100 $μ$G to several mG. In these conditions, synchrotron losses of positrons are significant that extends the range of acceptable values of positron injection energy. We show that if positrons injection in the GC is non-stationary and magnetic field is higher than 0.4 mG both radio and gamma-ray restrictions permit their energy to be higher than several GeV.

title: Strength-Based Physiological profiles of NCAA Division I Womens Basketball and Gymnastics Athletes: Implications for Injury Risk Assessment
Creators: name: Cazier, Curtis
Publisher: name: Utah State University
Year: 2017

description: The purpose of this study was to provide a comprehensive strength-based physiological profile of women’s collegiate basketball and gymnastic athletes; and to make sport-specific comparisons for various isokinetic and maximal and rapid isometric strength characteristics of the knee flexor and extensor muscles. A focus on antagonist muscle balance (hamstrings to quadriceps ratios, H:Q) will help elucidate particular vulnerabilities in these at-risk female athletes. Fourteen Division I collegiate level women’s basketball and 13 women’s gymnastics athletes performed isokinetic and isometric strength testing of the knee extensors and flexors. Outcome measures included absolute and body mass normalized (relative) isokinetic and isometric peak torque (PT) values, rate of torque development at 50, 100, 200 ms (RTD50, RTD100, RTD200) and H:Q ratios of all variables. The basketball athletes had greater absolute strength for all variables except for isokinetic PT at 240°s-1 and isometric RTD50 for the knee extensors. The gymnasts showed ~20% weaker relative concentric PT for the knee flexors at 60 and 120°·s-1, and decreased conventional H:Q ratios at 60 and 240°·s-1 (~15%) compared to the basketball team. These findings suggest that collegiate level gymnastics athletes may be prone to increased ACL injury risk due to deficient relative knee flexor strength and the associated H:Q strength imbalance. Optimizing strength training programs for collegiate gymnastics with increased focus on strength improvements for the hamstrings
may be a potentially effective strategy to help decrease the ACL injury risk.
title: Measuring the Adaptive Response to Drought

Publisher: name: Utah State University

description: Scientific evidence suggests that future climate change has the potential to bring about an increase in both the frequency and duration of drought in some regions of the world (United Nations, 2012). Economists have theorized that at least some of the adverse effects of these droughts will be mitigated through various adaptive responses by agricultural producers. The effectiveness of any adaptive response to climate change will depend on how quickly producers can recognize a change in climatic patterns and respond accordingly. The following paper investigates the relationship between a specific climate signal (prolonged drought) and the land use decision of a farmer. To accomplish this, we track changes in land use for roughly 50,000 farmers for 5 consecutive years in western Kansas. Using a two-way fixed effect model, we find a statistically significant negative association between drought and the decision to plant corn, a relatively more water intensive crop. However, the magnitude and statistical significance of these findings are quite sensitive to model specification. In addition, although statistically significant, the magnitude of this relationship appears to be small, suggesting that the pace of climate change adaption, with respect to drought and crop choice, may be quite gradual.
title: Diagnostic Considerations in the Identification of the Hyperactive Child

description: The hyperactive disorder of childhood and the enumeration of its features were described in two papers published in the mid-1950's, by Laufer and his colleagues (Laufer, 1957; Laufer, Denhoff & Solomons, 1956). It was a list that has since become familiar; short attention span, impulsivity, irritability, low frustration tolerance, poor academic achievement, and visual-motor difficulties. Like many who have since searched for definers of the syndrome, Laufer and his colleagues remarked upon the perplexing variability displayed by these children, and they noted that no single symptom could be considered diagnostic. They described the development of "secondary psychological difficulties" due to the irritating effect of the child's symptoms on parents and teachers. Laufer et al.(1956) issued one of the earliest warning against indiscriminate reliance on medication. They added a cautionary note, which would be resounded and elaboration by Whalen and Henker (1976), about the attributional effects of medication:

title: Imputation for Random Forests

Publisher: name: Utah State University
Year: 2017

description: This project introduces two new methods for imputation of missing data in random forests. The new methods are compared against other frequently used imputation methods, including those used in the randomForest package in R. To test the effectiveness of these methods, missing data are imputed into datasets that contain two missing data mechanisms including missing at random and missing completely at random. After imputation, random forests are run on the data and accuracies for the predictions are obtained. Speed is an important aspect in computing; the speeds for all the tested methods are also compared.
One of the new methods is more accurate than the other, about as accurate as the most accurate method for data that are missing at random, but the speed for both methods is much slower with bigger datasets. It was not as accurate as other methods when data are missing completely at random
Reformed Curriculum Framework: Insights from Teachers' Perspectives

description: The National Curriculum Framework 2005 envisions a reformed curriculum that connects knowledge and learning to the child’s context. While concerns of equity, accessibility, and social transformation have been aimed through education, the crucial link of ‘teacher’—instrumental in realizing these aims—seems missing. This study explores teachers’ views about mathematics, their understanding of children’s roles and issues of pedagogy within the context of the curriculum document. The paper is an attempt to bring forth the teachers’ perspective on a reformed curricula, the kind of constraints it poses upon them in practice and the lack of spaces for teachers to critically engage with the curriculum. Considering classrooms as rich resource for teacher learning ‘from’ practice, teachers need support structures and forums to discuss, evaluate, and enrich the curricular suggestions for reforms and critically inform practice.

title: Aftermath of An Almost: Exploring the Dialectics of Voice
Creators: name: Livingston, McKenzie
Publisher: name: Utah State University
Year: 2017

description: Writers trying to find an outlet for a painful event or problem may use poetry because it employs a “speaker,” or another voice with which to express deeper, often unexplainable feelings. This thesis project seeks to uncover different voices the poet uses to communicate opposing desires within herself, such as the desire to be obedient and a “good girl” juxtaposed with the desire to rebel and be independent. The speaker wrestles with six dialectic voices in this collection of poems, all of which compose a strange symphony of music which releases the speaker from any idea that she must have “one” voice—she can, and does, have many which coexist simultaneously. This discovery leads to a type of catharsis, not necessarily from societal norms dictating sameness, but from the idea that having multiple “personalities” or voices is undesirable. The poet experiments with humor and melancholy, tragedy and exuberance in order to avoid poetical stereotypes—that is, that all poetry must be “sad” or depressing. She of course acknowledges that sadness does exist, but not without its foil—joy—and so, her form and content weld together again, creating a dialectical tone.
title: An Examination of the Short Term Reversal Premium
Creators: name: Burgess, Timothy
Publisher: name: Utah State University

description: The intent of this study is to explore short-term reversal effects in public securities markets.
The basis of this study is to take into consideration prior work done by economists, paying particularly attention to periods specifically before and after the decimalization of the stock market in 2001. This study finds that from years 1980-2000, there is a monthly return premium of -0.0552% or 5.5 basis points, which is quite significant with a t-statistic of 11.08. Following decimalization in 2001 through year 2012, this monthly return premium drops 44% to -0.031% or 3.1 basis points, again with a high t-statistic of 4.50. Despite these findings, the resulting return premium is still quite small in nature and would require large capital commitments to realize any type of meaningful return. Regardless, there inherently appears to be an arbitrage opportunity that would pique the curiosity of any rational investor and begs to be explored further.

description: We show that the operatorial framework developed by Voiculescu for free random variables can be extended to arrays of random variables whose multiplication imitates matricial multiplication. The associated notion of independence, called matricial freeness, can be viewed as a generalization of both freeness and monotone independence. At the same time, the sums of matricially free random variables, called random pseudomatrices, are closely related to Gaussian random matrices. The main results presented in this paper concern the standard and tracial central limit theorems for random pseudomatrices and the corresponding limit distributions which can be viewed as matricial generalizations of semicirle laws.

description: Previous studies have used numerical methods to optimize the hyperpolarizability of a one-dimensional quantum system. These studies were used to suggest properties of one-dimensional organic molecules, such as the degree of modulation of conjugation, that could potentially be adjusted to improve the nonlinear-optical response. However, there were no conditions set on the optimized potential energy function to ensure that the resulting energies were consistent with what is observed in real molecules. Furthermore, the system was placed into a one-dimensional box with infinite walls, forcing the wavefunctions to vanish at the ends of the molecule. In the present work, the walls are separated by a distance much larger than the molecule's length; and, the variations of the potential energy function are restricted to levels that are more typical of a real molecule. In addition to being a more physically-reasonable model, our present approach better approximates the bound states and approximates the continuum states - which are usually ignored. We find that the same universal properties continue to be important for optimizing the nonlinear-optical response, though the details of the wavefunctions differ from previous result.

title: Image Segmentation Using De-Textured Images
Creators: name: Kodavali, Yaswanth
Publisher: name: Utah State University
Year: 2017

description: Image segmentation is one of the fundamental problems in computer vision. The outputs of segmentation are used to extract regions of interest and carry out identification or classification tasks. For these tasks to be reliable, segmentation has to be made more reliable. Although there are exceptionally well-built algorithms available today, they perform poorly in many instances by producing over-merged (combining many unrelated objects) or under-merged (one object appeared as many) results. This leads to far fewer or more segments than expected. Such problems primarily arise due to varying textures within a single object and/or common textures near borders of adjacent objects. The main goal of this report is to pre-process the input images to nullify the effects of such textures. We introduce a pre-processing technique that prepares the input images, before the application of segmentation algorithms. This technique has demonstrated an enhancement in quality of the segments produced. This pre-processing method is called the de-texturing method. We experimented with the effect of the proposed de-texturing method on two existing segmentation methods, namely, the Statistical Region Merging (SRM) method [1] and a k-means-based method as suggested in [2].

The balance between beauty and repulsion, as well as mindfulness and excess, is a paradox that is questioned and explored from concept to completion.
Working in an intuitive, yet methodical way, the experience of living with OCD is expressed as a parallel to the overwhelming growth patterns algal blooms exhibit. The observations and experiences that influence the work are most closely related to a memoir. The processes used to create the work are both digital and physical, involving a combined use of CNC (computer numerical control), computer aided design, plaster molds, and porcelain paper clay. As the forms repeat and evolve, the line between nature and technology comes into question.

title: A Comparison of Statistical Methods RElating Pairwise Distance to a Binary Subject-Level Covariate
Creators: name: Stone, Rachael
Publisher: name: Utah State University

description: A community ecologist provided a motivating data set involving a certain animal species with two behavior groups, along with a pairwise genetic distance matrix among individuals. Many community ecologists have analyzed similar data sets with a method known as the Hopkins method, testing for an association between the subject-level covariate (behavior group) and the pairwise distance. This community ecologist wanted to know if they used the Hopkins method, would their results be meaningful? Their question inspired this thesis work, where a different data set was used for confidentiality reasons. Multiple methods (Hopkins method, ADONIS, ANOSIM, and Distance Regression) were used to analyze the distance matrix for association with a binary covariate of interest. To compare the performance of the Hopkins method with the performance of the remaining, more established methods, a simulation was run. The results of the simulation indicate that ADONIS, ANOSIM, and distance regression would all be preferable to the Hopkins method.

description: This work investigates the use of compressed sensing to reduce measurement times in magnetic resonance imaging (MRI) and magnetic particle imaging (MPI). To this end, a flexible yet performant image reconstruction framework is developed. Based on this, an efficient reconstruction scheme for non Cartesian MRI is proposed and a low-rank-based method for the estimation of MPI system matrices is developed. Finally, an experiment design framework is developed to obtain optimized sampling patterns for both MRI and MPI.

description: In this paper we review some properties of fuzzy observables, mainly as realized by commutative positive operator valued measures. In this context we discuss two representation theorems for commutative positive operator valued measures in terms of projection valued measures and describe, in some detail, the general notion of fuzzification. We also make some related observations on joint measurements.

title: Expressive Inflection: Applying the Principles of Sergey Rachmaninoff’s Performance in My Own Practice
Creators: name: Lapshin, Konstantin

description: The interpretative approach called expressive inflection (‘intonatsiya’ in Russian) is relatively unknown to the Western music tradition. However, the term was actively in use by Russian musicians and pedagogues in the early twentieth century. In this thesis, I explore Sergey Rachmaninoff’s engagement with this approach demonstrated in his recordings through a practical portfolio of my own performance practice.
The purpose of this project is to consider possible applications of this method in performance today. The thesis offers a definition of expressive inflection in performance based on my own practical experience, informed by a consideration of writings of Rachmaninoff’s contemporaries, recorded performances of Rachmaninoff and other pianists who practised this approach. As part of this work I also offer a brief historical background to the term expressive inflection as well as a brief overview of Rachmaninoff’s pianistic career and recorded legacy.
Also in order to offer a broader picture of Rachmaninoff’s performance style and present it in the context of Western tradition, a single chapter of this work has been devoted to Rachmaninoff-pianist’s relationship with what may be called Romantic pianism. Here, more contemporary research on early recordings has been considered.
The portfolio of performances is accompanied by a commentary focusing on five case studies which focus on different applications of expressive inflection. For these studies I have chosen recordings of different works made by Rachmaninoff and the recordings of the same works produced by myself, as well as my own recordings of different works illustrating the ideas discussed in case studies and expanding them further. The choice of Rachmaninoff’s recordings reflects my aim to incorporate various details of the approach in a comprehensive and convincing way. Within these studies, several topics have been considered: tempo fluctuation and micro-rubato as part of expressive inflection; expressive inflection as a tool in building imaginative framework of a piece; expressive inflection as a tool in structuring a work; and the ways in which interpretations evolve over time.

death in children's literature
OurMythicalChildhood

description: According to Grzegorz Leszczyński, stereotypical approaches to the phenomenon of death in children's literature include: orphan-hood of protagonist, death of the enemy and heroic death of the main character. All those elements can be found in Harry Potter books. In this article I present an interdependent type of Harry and Lord Voldemort's relationship in the context of death in its various realizations. The main figure of the analysis is Harry Potter himself, boy that from the beginning of the story has a piece of Dark Lord inside him - as a child-horcrux. This article traces the motif of death in Harry Potter series and its relation to the concept of child and childhood.

description: A new method is developed for prediction of UT1. The method is based on construction of a general harmonic model of the Earth rotation using all the data available for the last 80-100 years, and modified autoregression technique. A rigorous comparison of UT1 predictions computed at SNIIM with the prediction computed by IERS (USNO) in 2008-2009 has shown that proposed method pro-vides substantially better accuracy.

Year: 2023

description: We use the real space renormalization group to numerically analyze the 2D Random Ising Model for a system with a boundary. We detect the critical points by studying the cluster percolations and the spontaneous magnetization at the end of the numerical decimation procedure. We use this to derive the phase diagram for the model depicting the different boundary criticality classes of the theory.

title: Evaluation of Long-term Effects of Mild Traumatic Brain Injury on Visual Motor Control of NCAA Division I Football Athletes
Creators: name: DeLost, Kathryn
Publisher: name: Utah State University
Year: 2017

description: Context: Current concussion evaluation assessments rely largely on static measures that may not detect subtle changes in behavior. Dynamic evaluation, such as visual-motor tracking tasks, may reveal subtle and meaningful changes in motor behavior post-concussion. Objective: This study compared measurements of performance regularity over a time series (approximate entropy; ApEn), which was derived from a visual-motor tracking task performed before concussion, post concussion, and at one month, three months, and six months post concussion. ApEn values were compared for number of previous concussions and playing position groups. Design:  ApEn values were collected from the visual-motor tracking task, and history of concussion and playing position were obtained from an intake questionnaire. Post-test ApEn values were collected from participants who sustained a concussion during the study along with control subjects (matched by age and date of pre-test). Setting: Testing occurred in an office in the athletic training room, which matches the typical setting for pre and post-concussion testing. Participants: Ninety-nine Division I football athletes were baseline tested. Six concussed subjects were pre and post-tested along with 11 control subjects. One of those six was post-tested at one, three, and six months, while two were post-tested at injury, one month, and three months along with one control subject. Task and Procedure: The subject was seated at arm’s length from a laptop, pressed the distal joint of his index finger against a force plate and traced a line presented on the computer screen. Visual feedback was not displayed on the screen for the no-vision condition. An algorithm calculated ApEn from the output. Results: Post-test ApEn values were not significantly lower when compared to pre-test values and values of control participants. There was a significant effect of position group on ApEn scores, but not RMSE. There was not a significant main effect of previous number of concussions on ApEn, but ApEn was significantly lower in those with two or more previous concussions compared to those with one.

description: This research aims to conduct a stylistic analysis of selected content from TikTok using both lexical and semantic approaches. The study analyzes the meanings of sentences and phrases used by content creators on TikTok, as well as various figurative devices employed. A qualitative method was used to conduct the analysis, and the selected content was categorized under various stylistic analysis categories, including semantic parallelism, semantic deviation, lexical deviation, lexical parallelism, and code mixing. Neologism, lexical parallelism, and code mixing were examined under lexical stylistics analysis. Two content creators and five videos from each were selected for the analysis. The study found that both content creators used semantic and lexical parallelism to emphasize specific ideas and create humorous effects in their videos. Additionally, specific stylistic devices were used to convey subliminal messages, including taunting politics, highlighting an increase in robbery cases, and criticizing married life.
