Item Restricted ALIVE LONG FRIEND: HOW DOES MEREDITH GREY’S EVOLUTION IN GREY’S ANATOMY’S SCREEN NARRATIVE CULTIVATE A SENSE OF ONTOLOGICAL SECURITY AMONGST FANS?(School of Sciences and Humanities, 2023) Zhakupova, AidanaThe idea of "ontological security" is becoming popular in recent years since it describes the sense of constancy and continuity that people feel in their lives. This notion becomes particularly relevant to the fans of Grey’s Anatomy because after watching a popular medical drama they feel safe and stable in their daily life. Ontological insecurity is portrayed in the episode in a way that illustrates how people can become uneasy and confused when their core worldviews are questioned. For instance, the characters in Grey's Anatomy constantly encounter and resolve circumstances in which their morality, interpersonal connections, and professional competency are called into question, which causes vulnerability and anxiety. However, fans facing the same situations do not feel vulnerable or anxious in their real life because of Grey’s Anatomy characters, who are role models to them and provide fans with a sense of ontological security.Item Open Access Alpamys Batyr and Odysseus: Fidelity or Death?(Nazarbayev University School of Sciences and Humanities, 2020) Myrzabekova, KundyzThis capstone project aims to find the main similar themes raised in the stories “Alpamys” and “Odysseus” and will try to find why these topics, particularly the issues of fidelity were discussed and what is the role of it in each story. The reason for the comparison of these two stories is in the similarity of the topics raised in the text. Both, the story of “Alpamys” and the story of Odysseus present the issues of loyalty and homecoming. Before starting comparison, it was crucial to determine the origin of each story and to identify if they influenced each other. The finds showed that the story of “Odysseus” appeared much before the “Alpamys”, in the 8th century in an isolated island, while “Alpamys” takes its origin from the story of “Bamsi Beyrek” that emerged after 10th century on the Altay mountains. Since both stories have different places and dates of origin, the possibility of their contact and impact on each other is excluded. The analysis of the story shows that fidelity that main heroes kept toward their spouses, toward their friends and land assisted them to survive and return to home, despite the struggles and obstacles they faced on their way. Since Penelope stayed loyal to Odysseus until the end, she avoided marriage to one of the suitors, as well as Gulbarshyn that kept her fidelity to Alpamys. And Odysseus and Alpamys could return home because they were Fidel to their land and to their families since otherwise, Odysseus would live in captivation by Calypso, while Alpamys under captivation of Taycha-Khan.Item Open Access ANALYSIS OF BACTERIOPLANKTON COMMUNITIES IN TENGIZ-KORGALZHYN LAKES SYSTEM USING FULL-LENGTH 16S NANOPORE SEQUENCING DATA(School of Sciences and Humanities, 2023) Len, PolinaTengiz-Korgalzhyn Lakes system, designated under the Ramsar Convention and UNESCO World Heritage Sites, is a unique ecosystem of wetlands inhabited by more than a hundred protected and endemic species. In the context of the constant ecological pressure in the area, it is critical to investigate the lake bacterioplankton species and their relationship with abiotic factors, especially since microbiome studies of the region are practically absent in the literature. This study aims to investigate the role of salinity gradient in shaping bacterial communities in lake ecosystems, as well as the extent to which the overall abiotic factor explains the heterogeneity of microbiome composition across the region. Data on microbial communities is based on the full-length 16S amplicons obtained with the MinION mk1c. Species-level classification and analysis are performed in Emu, R , and R Studio, using packages phyloseq and vegan. Our research has confirmed the importance of the salinity gradient in shaping the microbiome composition in limnetic and oligohaline lakes. We have shown that out of all abiotic factors, salinity exerts the most influence on the composition of microbial communities. The abundance of Beta- and Gammaproteobacteria classes changed in parallel with raising salinity levels across all sampling sites: decreasing and increasing, respectively. Moreover, salinity negatively correlated with the community evenness index across distinct small lakes, implying the presence of dominant species. The high degree of variability between isolated water bodies was mainly attributed to the geographical separation.Item Open Access Analysis of Dead Core Phenomena in Reaction-Diffusion Problems(Nazarbayev University School of Sciences and Humanities, 2020-05-10) Sabit, FarizaFor some semilinear parabolic problems of reaction-diffusion, a dead core - a region of zero reactant concentration - may be formed in finite time. We study the large time behavior of the solution and give an estimate for the asymptotic behavior of the solution of a semilinear heat equation with Robin boundary condition.Item Open Access ANALYSIS OF MAXIMUM MEAN DISCREPANCY GENERATIVE ADVERSARIAL NETWORKS (MMD GAN)(Nazarbayev University School of Sciences and Humanities, 2024-04-28) Kaiyrbekov, TemirlanDeep neural networks can be used to generate new data by sampling from the data distribution without explicitly defining the distribution. These nets heavy rely on optimization for efficient learning, and hence, they need mathematical guarantees for feasibility of learning. Generative Adversarial Networks (GAN) were proposed to generate images by the use of a mini-max objective function that is ”played” among two agents - a generator and a discriminator network. Later, Generative Moment Matching Networks (GMMN) were proposed to use a two-sample test instead of a discriminator network. GMMN uses Maximum Mean Discrepancy metric for distinguishing between real and generated images, but it only trains the generator network, and was implemented inefficiently. Lastly, Maximum Mean Discrepancy Generative Adversarial Networks (MMD GAN) were introduced that use adversarial kernel learning that has a mini-max objective function, efficient learning and mathematical guarantees that justify its improved performance. In this work, the mathematical reasoning behind the idea of MMD GAN was analyzed and experiments were made to tweak the parameters of the network. The loss function of MMD GAN is said to enjoy a weak topology - that MMD should tend to zero as two probability distributions converge to each other - and it will be shown empirically. Also, since the network has a loss function that is locally Lipschitz and continuous everywhere, and almost everywhere differentiable, the network was able to learn efficiently. Finally, MMD GAN with changed bandwidth parameters will be introduced that showed improved convergence with less MMD loss during training, although the loss was less smooth over epochs.Item Open Access ANALYSIS OF THE MATHEMATICAL MODEL DESCRIBING THYROID-PITUITARY HORMONAL TRANSPORTATION BY A SYSTEM OF NONLINEAR ORDINARY DIFFERENTIAL EQUATIONS(Nazarbayev University School of Sciences and Humanities, 2022-05) Baidildayeva, AishaThe main goal of this capstone project is to conduct the analysis of the mathematical model which describes the transportation of the thyroid pituitary axis of the hormones within the endocrine system. The model is constructed by a system of ordinary nonlinear differential equations that represent the fluctuations of the levels of the concentration of thyroxine hormone in the blood and illustrate its dependency on the concentration of certain enzymes. This capstone project will assess the stability of the system by applying the well-known Routh-Hurwitz criteria, conduct nu merical simulations, and use MATLAB with the purpose to visualize the general behaviour of the system. The derivation of the analytical solution separately for normal and degenerate states of the system is also presented in the paper. Lastly, the phenomena of relaxation oscillations that was noticed to take place during the derivation of the analytical solution will be explained. The research has shown that there is a direct correlation between the periodicity in the changes of the levels of thyroxine hormone in the blood and the presence of the symptoms of the schizophrenia. The current capstone project can be improved by modifying the model such that it includes the discrete and distributed delay cases during the trans portation process.Item Restricted ANTIBODY GENERATION FOR DETECTION OF PHOSPHOGLYCEROYL PROTEIN ADDUCTS(Nazarbayev University School of Sciences and Humanities, 2024-04-20) Shatkenova, ZariatOne of the reactions of glycolysis, which is controlled by the enzyme GAPDH, results in the synthesis of 1,3- bisphosphoglycerate. A highly reactive intermediate product known as cyclic 1,3-phosphoglycerate (cPGA) can be formed from 1,3-bisphosphoglycerate. In previous studies, it was shown that the knock-out of PARK7/DJ1 can cause an accumulation of highly reactive cPGA and its adducts. However, the quantifiable methods to detect cPGA adducts were lacking. We created a novel technique for the detection of cPGA modifications with antibodies specifically recognizing cPGA-modified lysine and cysteine residues. We developed a procedure for the generation of antigens modified by cPGA. We produced antibodies that recognize lysine and cysteine residues modified by cPGA. Finally, we purified these antibodies by negative selection with the help of affinity chromatography. Our results demonstrated that purified antibodies can specifically recognise a diverse range of cPGA-modified proteins and can be used for Western Blot analysis of cell extracts.Item Open Access APPLICATION OF 4-DIMENSIONAL COPULAS IN CALCULATING VALUE-AT-RISK FOR THE PORTFOLIO OF 4 SP500 COMPANIES(School of Sciences and Humanities, 2023) Bolatbekov, KairzhanPortfolio risk management is a process aimed at maintaining profit streams and reducing uncertainties in investment decisions. Value-at-Risk (VaR) is a widely used metric to quantify the potential loss of profits. Although historical simulations and Gaussian distribution are common methods for estimating VaR, modelling the joint multivariate distribution of portfolio investments can be challenging. Copula models offer a solution to these challenges for joint distributions. In this study, we calculated VaR and Conditional Value-at-Risk (CVaR) for a portfolio consisting of the four least correlated stocks among the 15 largest companies in the SP 500 using historical simulations and copula models. We evaluated portfolio based on equal weighting. The optimal ARIMA-GARCH model was selected using Akaike Information Criteria (AIC) values. Furthermore, the performance of the VaR estimations was compared and analyzed using goodness-of-fit tests.Item Restricted ARCHAEOLOGISTS’ APPROACH TO GENDER AND BIOLOGICAL SEX WITH CONCENTRATION ON IRON AGE ERA IN KAZAKHSTAN(Nazarbayev University School of Sciences and Humanities, 2024-04-24) Saktaganova, GaliyaThis research explores whether archaeologists in a specific Kazakhstani concept have utilized and applied the concepts around gender and biological sex, and whether current perceptions of gender have influenced their conceptions. The researcher has conducted interviews with anthropologists working in Kazakhstan, as well as has done some participant observations on lectures centered around gender and anthropological methodologies. This research has examined the current state of the debate revolving around concepts of gender and sex in Iron Age archaeology, and explored one of the many conversations centered around the ways gender and sex is being discussed in Kazakhstani archaeology.Item Restricted ASTRA BUS PER ASPERA: INFLUENCE OF SOCIAL INTERACTIONS IN COMMUNITY BUSES ON IDENTITY FORMATION(Nazarbayev University School of Sciences and Humanities, 2024-04-22) Azetova, LailimPublic transportation is very important for people, especially in big cities like Astana. People of all ages are using public buses, and forced to interact with each other one way or another on a daily basis. The study focuses on those interactions in public transport, and its influence on identity formation of people. The study is qualitative, consisting of 2 parts: participant observation and interviews. The participants were chosen using snowball sampling, and distributed into 3 age groups: young adults (18-30), middle-aged people (30-60), and elderly (60+). The content was analyzed by using the theory of symbolic interactionism. The result showed that public transport is not viewed as a place for public interactions. Instead it is a place of solitude despite the limited space the bus creates. Majority of the people prefer to keep to themselves, instead of interacting with strangers or even acquaintances. Public interactions are initiated only when needed, and only for the sake of everybody else’s comfortItem Open Access Back to the Roots: Contemporary Kazakh And Mexican Graphic Novels(Nazarbayev University School of Sciences and Humanities, 2020-05-01) Malika, KanashevaThe pre-colonial setting has been a great source of inspiration for young comic book artists in Kazakhstan and Mexico. If artists such as Eduardo Ancer and Gonzalo Alvarez use pre-Hispanic Mesoamerica, its ancient culture, and mythology, Kazakh artists such as Madi Musabekov and Orazkhan Zhakyp heavily focus on Turkic mythology and the formation of the Kazakh Khanate in their works. The trending search for cultural background and ancestral reconnection can represent an interesting stage of postcolonial development and the formation of cultural identity among the youth. Unlike Mexico, which has fought for its acknowledgment in postcolonial studies, Kazakhstan still cannot redefine its post-Soviet experience as postcolonial. Both countries, similarly to many other postcolonial nations, have been experiencing a crisis of cultural and national identity, particularly the youth that stays in-between cultures. With the reemergence of transculturalism, which proposes acceptance of cultural fluidity, there is a challenge in its co-existence with the reinforcement of precolonial history through graphic novels. Since the project focuses on the cultural identity of youth, graphic novels demonstrate a promising discussion of postcolonialism and contemporary youth resistance. Thus, with this project, I attempt to redefine the concept of ‘postcolonial graphic novels’ and analyze the reconstruction of Kazakh and Mexican cultural identity through postcolonial and transcultural perspectives.Item Restricted BALANCING WORK AND STUDY AT NEO-LIBERAL UNIVERSITY: MOTIVATIONS AND SOCIAL EFFECTS OF PART-TIME EMPLOYMENT AMONG NU UNDERGRADUATE STUDENTS(Nazarbayev University School of Sciences and Humanities, 2024-04-24) Shopanova, SofiyaCapstone project investigates the motivations of Nazarbayev University (NU) students for engaging in part-time work with their studies, within the consideration of the university as a neo-liberal institution. The study explores the influence of neoliberal policies shaped by Kazakhstan's post-Soviet political climate under President Nursultan Nazarbayev, which emphasize privatization, meritocracy, individualism, self-reliance, and competition. It assesses the effects of these policies on the educational system overall and thus students' academic performance, personal life, health, and career opportunities through seven semi-structured interviews. The project employs three main theoretical perspectives: Self-Determination Theory to evaluate personal motivations for work; The New Spirit of Capitalism to understand corporate expectations and self-exploitation; and Ecological Systems Theory to analyze socio-ecological influences on students' decisions. The findings aim to provide insights into how a neoliberal educational environment like at NU, which prioritizes corporate competitiveness and professional flexibility, motivates students to work and impacts their lives and career paths.Item Open Access BARAM, KELEM, ISTEVATRM: THE ROLE OF PHONOLOGICAL REDUCTION IN FORMING IDEOLOGIES ABOUT WESTERN KAZAKH SPEECH(Nazarbayev University School of Sciences and Humanities, 2024-04-11) Turaliyeva, ZhansayaPeople in Kazakhstan often perceive the speech of individuals from the Western regions of the country negatively. Reports from speakers of other regions claim that Western Kazakh (WK) speech is rude and understanding it is difficult. Hereby, my capstone examines that WK speakers tend to reduce phonologically the most frequently and due to it, the negative attitudes towards WK speech exist. My studies reveal that WK speakers do employ phonological reduction more often. Specifically, Westerners phonologically reduce verbs 50% more than North-Eastern Kazakh speakers. The data was collected from MultiCorSKL recordings. I have analysed 5 minutes of each of the 8 speakers from both dialects. This finding suggests that phonological reduction may explain why WK speakers are perceived to be fast speakers. The most frequent examples were producing “деймін” as “дим” and “барамын” as “барам.” To understand how the perception of this phonological feature is extended by listeners to moral assessment about WK speakers, I aimed to show the steps through which phonological reduction is iconized into evaluations of rudeness in the case of WK speakers. Iconization is a process through which language users infuse structural linguistic elements with symbolic significance, often reflecting cultural values or moral judgments (Irvine and Gal, 2000; Chen, 2018). To address this question, I conducted a matched-guise experiment. Participants from different regions of Kazakhstan listened to an 1-minute audio sample of spontaneous conversation, which was recorded by a WK speaker, without knowing the dialect and had to guess the dialect solely based on the audio. Half of participants successfully identified the dialect as WK, while the rest identified the dialect as Southern. This suggests that the dialect is not readily distinguishable to native speakers of Kazakh unless they are informed that the speaker is from the Western region, and consequently, speaks WK. Subsequently, I analyze the responses of these participants to identify whether they perceive WK negatively and if so, the reasons behind such perceptions. People indicate that the negative perceptions may result from cultural beliefs associating the Kishi Juz, inhabitants of the Western region, with traits like cruelty and aggression due to being historically known for their warrior heritage. Moreover, every participant agrees that the frequent reduction of verbs in the speech affects their comprehension more, which makes them feel irritated. These results indicate that the negative attitudes towards the WK are primarily ideological constructs, which may not be negatively perceived in the absence of relevant information. Taken together, these results suggest that the frequent phonological reduction of WK speakers may affect the negative attitudes about WK being shaped. References Chen, S. C. (2018).

An important point in the research process was also to identify what is actually meant by the term “informal communication”. Are they really casual conversations and interactions that happen outside of formal business meetings? This capstone project is focused on understanding the role that these informal interactions play in building social capital, that is, the networks and relationships that help a Startup grow. In particular, the research questions intend to identify how these communications differ from formal ones and what their impact is on the development of Startups in the Kazakhstan ecosystem. The findings reveal that informal communications are more than casual, and they may even represent strategic exchanges, which have a meaningful contribution to the generation and maintenance of social capital within the startup community. These communications have more of an informative nature in regard to shared knowledge, resources, and support for each other, in an environment that is much less official and trustful for deeper connections on a personal and professional level. What is more important is that the study found that these informal networks are critical to how investment is secured and how collaborations are created in a way that one cannot access solely from formal channels. For instance, in Kazakhstan, social relationships and trust can be invaluable, so the role of these informal communications might be irreplaceable in guiding the startup ecosystem toward growth.Item Restricted BELIEF SYSTEMS, RITUAL AT LATE IRON AGE TASBAS, KAZAKHSTAN(Nazarbayev University School of Sciences and Humanities, 2024-04-24) Nygmetzhanova, AizhanThis capstone project examines the single burial from the Late Iron Age period in East Kazakhstan. Earlier analysed in the dominant processualism framework, which relies on material culture, the individual agency and lived experience in shaping cultural practices were underestimated. Therefore, this project explores belief systems and rituals of the Wusun incorporating both processual and post-processual approaches. The multi-aspect analysis was used including osteological analysis, grave good analysis and burial features analysis. The results of the examination of the mortuary practices at Tasbas provided the exploration of multi-aspect identities of the individual within the Wusun social and cultural contexts. With the interplay between individual’s agency, social identity, and embodied experience we were able to get a deeper understanding of the complexity of Wusun society as well as the ways in which their lived experiences were influenced by both internal and external factors.Item Embargo BOUSSINESQ EQUATION IN ELASTIC RODS.(Nazarbayev University School of Sciences and Humanities, 2024-04-19) Zhardemova, NazerkeIn this project, the goal is to consider the equation of the transverse deflections of the rod when it is firmly connected to an elastic foundation. We study the well-posedness of the corresponding Cauchy problem, that is, existence, uniqueness and persistence properties of the solutions inherit by the initial data. Moreover, we will also find the conditions under which the solutions can extend globally in time in $L^2$ and the energy space $X$. Furthermore, we establish the persistence decay properties of the solutions in $X^s$.Item Open Access Brick-By-Brick: A Construction of ’t Hooft’s Brick Wall(Nazarbayev University School of Sciences and Humanities, 2020) Gilman, NarynbekA pedagogical construction and review, aimed at the undergraduate level, are given of the brick wall model. The brick wall is a finite region just outside the event horizon of a black hole. It is introduced in order to calculate the entropy of the collapsed star. The statistical origin of the entropy is still unknown, but the brick wall model offers an elementary exercise in counting quantum field solutions to arrive at the famous entropy-area result. The brick wall is a cut-off, effectively regularizing an otherwise divergent result. The model encompasses many fields of physics, including general relativity, quantum theory and statistical mechanics. Its multidisciplinary approach hints at what a more sophisticated solution will look like to the problem of a statistical explanation of the entropy of black holes.Item Open Access BROTHER FROM ANOTHER MOTHER: THE NARRATORIAL STRUCTURE OF OSAMU DAZAI’S NO LONGER HUMAN AND ALBERT CAMUS’ THE STRANGER(Nazarbayev University School of Sciences and Humanities, 2024-04-11) Kudaibergen, MadiThe research project focuses on the analysis of narration in Osamu Dazai’s No Longer Human (人間失格, 1948) in comparison with Albert Camus’s The Stranger (L’Étranger, 1942). How do the circular/linear structure and the I-Novel (shishōsetsu is an old Asian genre of autofiction confession novels) genre conventions affect the absence of a climax in the narrative of those novels? In most of the past English-language articles and essays (Hoye 2011; Muratore 2011; Ueda 1990; Wolfe 1990), the nature of Dazai’s and Camus’ narrative has been closely related to the thematic pattern of suicidal narrative or existentialism and the surface-level of basic plot symbolisms. Not much of a comparative analysis has been done in narratological terms except for informal online posts examining similarities between Dazai and Camus. The capstone project seeks to fill that gap and deepen our understanding of non-Western narrative by addressing No Longer Human as a unique piece that might reform even some basic theoretical categories within the narrative theory field. That is because the Eastern narrative tradition was mostly autonomously developing its unique plotless narration till the 19th century and then was affected by Western cultures (Wolfe 15). Dazai is a member of the 3rd generation of modern Japanese writers affected by Western literature and yet he is called the last I-Novel, which makes his novel a mix of both traditions (Lyons 4; Wolfe XV). This kind of unique work always broadens the understanding of possible borders that literary prose can achieve. The main findings were obtained by close reading and delineation of general narrative terms such as focalization, narrator, and climax, conceptualized by Gérard Genette (1983). They are used to show how the generic concepts of the Japanese I-Novel we may trace in both works either follow or do not fit the established categories. By this I mean the feature of I-Novel being strongly autobiographical and plotless, while Western authors traditionally were detached from the work and prose was strongly plot-based. The prologue and suicide scene for No Longer Human show the two-levelled narration, biographical origins and detachment. The murder scene and confession scene for The Stranger show the climax point that changes the narration and plotless nature of the novel. Those scenes provide most of the narrative devices and carry the same false climax points. Analysis showed the presence of narrative circularity and two unreliable narrators in No Longer Human. The final step is to contrast Dazai’s narrative discourse to Camus’s much less polymorphic linear structure. One of the unforeseen discoveries is the nature of The Stranger as the French variation of the I-Novel, followed by more similarities in the background of the genesis of novels. The autobiographical notion is easily traced in The Stranger, the same as the personal beliefs are confessed. Finding notions of I-Novel outside of Asia can be the new approach to analysing non-Asian literature in narratological terms. It can help to trace the development of literary traditions and potentially find or predict the future modifications of prose fiction.Item Open Access CALCULATIONS OF VALUE AT RISK FOR THE PORTFOLIO OF 5 S&P 500 STOCKS USING 5-DIMENSIONAL COPULA FUNCTIONS(Nazarbayev University School of Sciences and Humanities, 2024-04-19) Kakenov, AssanaliThe purpose of this project is to compare copula estimations of Value at Risk (VaR) for a portfolio of 5 S&P 500 stocks to historical, normal distribution, and Monte Carlo methods employing dependence measures and ARIMA-GARCH time series models. This study will provide interpretations of financial data between 2019-2024 in a scope of 5 equations: Gaussian, Clayton, t-Copula, Gumbel, and Frank copulas. Correlations between closing prices of the largest 30 S&P 500 companies by market capitalization were calculated, and the portfolio was constructed by selecting 5 stocks with the least average correlation. The Markowitz portfolio optimization model was utilized to estimate the weights of the assets in the portfolio. Log returns, skewness, kurtosis, Shapiro-Wilk, and ADF were measured to describe stationarity and normality of the data. Data autocorrelation was assessed using ACF and PACF for volatility before ARIMA-GARCH modeling. All methodology was followed by appropriate hypothesis tests. Finally, 5-dimensional copulas were used for the VaR estimations for different confidence intervals. While AIC and BIC showed that t-copula was the best fit, the Clayton copula passed the goodness-of-fit test with the largest p-value. Subsequently, the Clayton copula generated VaR estimations closest to the historical data. The method used in this study can be extended for more than five assets without theoretical obstacles.Item Open Access CAPSTONE PROJECT: PITCH CHANGE IN KAZAKH-RUSSIAN-ENGLISH MULTILINGUAL YOUNG ADULTS(School of Sciences and Humanities, 2023) Isteliyeva, AidaIf you ever interacted with the same person in different languages, you might have noticed their voice sounding differently. This phenomenon is the object of this study about the change of pitch Kazakh-Russian-English trilinguals exhibit in speaking different languages. A physical representation of a human's pitch is fundamental frequency - the frequency with which vocal cords vibrate during speech. To see whether a change of pitch can be proved empirically, I conducted a series of recordings among 32 students of Nazarbayev University. This resulted in 192 recordings which were grouped depending on the gender and the first language of the speaker, as well as the elicitation method. The recordings were analyzed for each separate participant and in groupings using a t-test and linear mixed effect model. The participants also had to provide us with their self-assessed level of linguistic skills and their linguistic repertoire. The possible explanations for our results were provided by previous research in Bilingualism studies and Psycholinguistics. My study results in several findings regarding the interaction of different factors and the change of pitch. One of them is that the change of pitch seems to depend on the first language of the speaker. The change of pitch overall does not exhibit universal tendencies: separate analysis for each of the participants shows that change of pitch exists as it manifests in 28 out of 32 participants, however, there is no single reason or interaction that attests to all of the differences present in my data. Confidence level also shows a significant result for Kazakh speakers but not the others.
