The Bobwhite Population Decline: Its History, Genetic Consequences, and Studies on Techniques for Locating and Assessing Current Populations

Description: The northern bobwhite (Colinus virginianus) population decline is a severe, rangewide phenomenon beginning >150 years ago and continuing today. In this investigation, I: 1. document the timeline of bobwhite population decline and unintended genetic consequences of attempted remedies, 2) develop a model useful for predicting possible locations of potentially sustainable bobwhite populations in semiarid rangeland in Texas and Oklahoma, and 3) examine the relationship between population monitoring data and meteorological factors. While breeding season call counts of male bobwhite have been used for >70 years to provide estimates of fall populations for hunting, most studies of call counts have focused on mathematics and statistical accuracy of the count, largely overlooking the influence of meteorological factors on call counts. Here, I present the results of >4,400 individual point counts and examine their relationship with meteorological variables recorded at each stop. Humidity was positively correlated with the number of birds recorded (ρ = 0.275, p < 0.001) and temperature was negatively correlated (ρ = -0.252, p < 0.001). The number of birds recorded was significantly higher in wet years than in drought years. There was no significant correlation between wind velocity and number of birds recorded. These results suggest that, while weather does influence call counts and efforts should be made to record meteorological conditions when collecting call count data, the influence of weather may not easily factor into the analysis. These results also provide another line of evidence for decreased breeding behavior during high temperatures. With the increased focus on bobwhite habitat management on a regional scale, there is a need for reliable methods to identify potential bobwhite habitat. To identify bobwhite habitat in semiarid rangeland, I performed classification of LANDSAT scenes of Clay County, Texas from July and December 2015. Stands of mature little bluestem provide excellent bobwhite nesting cover ...

The Sexual Victimization of Black College Women

Description: Sexual victimization is a pervasive mental and physical health issue with overarching implications for university campuses and victim service providers alike. While a large expanse of research exists on sexual violence and the factors associated with victimization, less is known about the potentially unique experiences faced by Black college women in particular. Utilizing data collected by the National Longitudinal Study of Adolescent to Adult Health, this study examines the prevalence of college sexual victimization, levels of social support for victims and non-victims, intimate partner sexual victimization (IPSV), and the predictability of self-esteem on sexual victimization. In addition, comparisons are made between Black college women and their White counterparts. After conducting multiple t-tests and logistic regression analyses, results indicated that Black college women were more likely to experience IPSV than White college women, and Black college women received less social support following sexual victimization than Black non-victims. These findings can help in establishing more efficient and accessible assistance for victims.

A Study on Flat-Address-Space Heterogeneous Memory Architectures

Description: In this dissertation, we present a number of studies that primarily focus on data movement challenges among different types of memories (viz., 3D-DRAM, DDRx DRAM and NVM) employed together as a flat-address heterogeneous memory system. We introduce two different hardware-based techniques for prefetching data from slow off-chip phase change memory (PCM) to fast on-chip memories. The prefetching techniques efficiently fetch data from PCM and place that data into processor-resident or 3D-DRAM-resident buffers without putting high demand on bandwidth and provide significant performance improvements. Next, we explore different page migration techniques for flat-address memory systems which differ in when to migrate pages (i.e., periodically or instantaneously) and how to manage the migrations (i.e., OS-based or hardware-based approach). In the first page migration study, we present several epoch-based page migration policies for different organizations of flat-address memories consisting of two (2-level) and three (3-level) types of memory modules. These policies have resulted in significant energy savings. In the next page migration study, we devise an efficient "on-the-fly'" page migration technique which migrates a page from slow PCM to fast 3D-DRAM whenever it receives a certain number of memory accesses without waiting for any specific time interval. Furthermore, we present a light-weight hardware-assisted address reconciliation process for address management of the migrated pages. Such an on-the-fly page migration with hardware-assisted address reconciliation technique provides significant performance improvement over systems using epoch-based page migration and OS-based address management. Finally, we have developed an analytical model, which employs offline analyses of memory access counts per page and recommends whether an application is migration friendly or not. This can be useful in deciding if page migration (either epoch-based or on-the-fly based) should be used or turned off for a given application. Thus, our data management techniques and model enable significant performance improvements for flat-address heterogeneous memory ...

Four Evening Service Settings of Joel Martinson: An American's Contribution to Anglican Evensong Repertoire

Description: The Evening Service settings of great British composers like Charles Stanford, A. Herbert Brewer, Charles Wood and Herbert Howells are well known and performed often throughout the world. However, little is known about the body of settings created by American composers. There are currently approximately 75 American composers dating from 1890 to the present, with Evening Service settings in print. Joel Martinson, based in Dallas, Texas, is an American composer, church musician, concert organist, and presenter. Although Martinson has composed four Evening Service settings (Evening Service for the St. Mark's School 1996, Evening Service for the Incarnation 2000, Evening Service for Church of the Nativity 2002, and Evening Service for the Transfiguration 2015), these works are not widely known outside of Dallas and small Anglican circles, nor is the value of his contributions to Anglican Evensong repertoire recognized. The purpose of this study is to demonstrate that Martinson's four settings make a valuable American contribution to Anglican repertoire through his neo-classical style and creative counterpoint. The four settings are modern and challenging but remain approachable for both choir and audience.

Bouncing Back: Resilience as a Moderator between Aggression and Depression in Older Gay Men and Lesbians-Group Differences

Description: Older gay men and lesbians may be at greater risk for depression than older sexual majority adults due to a lifetime of sexual minority stress. We hypothesize that aggression and being single are positively associated with depression. Resilience is negatively associated with depression. Aggression, being single and resilience account for a significant proportion of variance in depression. Resilience moderates the relationship between aggression and depression. Significant differences between older gay men and older lesbians' aggression, resilience and depression scores exist. For our older gay men and lesbian combined group, a moderation analysis indicated that in addition to aggression and resilience, being single significantly predicted depression accounting for approximately 57% of the variance in depression. Furthermore, resilience significantly moderated the relationship between aggression and depression in our model of older gay men and lesbians. For our older gay men-only group a moderation analysis (indicated that and resilience significantly predicted depression accounting for approximately 57% of the variance in depression. Furthermore, resilience significantly moderated the relationship between aggression and depression in our model, in our sample of older gay men. Four our lesbian-only group a moderation analysis indicated that being single and resilience significantly predicted depression accounting for approximately 54% of the variance in depression.

Development and Testing of Gold(I) and Europium(III) Based Sensors for Environmental Applications

Description: This dissertation focuses on the development, characterization, and analysis of luminescent materials and coatings for sensing applications, including CO2, heavy metals, and silver. Chapter 2 involves the use of a gold(I) pyrazolate trimer that is able to detect silver ions with an AgNP medium. Detection of silver is vital, because there is an influx of silver into our environment caused by the increased use of AgNP. Therefore, having a sensor that is able to differentiate between and detect only Ag ions is an important first step to solving the toxicity mystery of AgNPs. Chapter 3 focuses on the development of sensor coatings containing a Eu(III) based luminescent system for sensing dissolved CO2 without the aid of an absorption-based dye. It is well-known that monitoring CO2 levels in our environment is important since even at low concentrations it can cause adverse health effects to the human body. This work demonstrates a pH-sensitive Eu complex being used directly as a CO2 sensor without the aid of any other absorption-based dye. Chapter 4 explores the idea of developing a heavy metal sensor for lead and its ability to detect lead in wide concentration range upon changing the pH of the medium and the polymer matrix. Different heavy metals have toxicity at different concentrations, therefore, being able to change the dynamic range of the sensor is advantageous. This research is the first step towards developing a luminescent Pb sensor with a tunable dynamic range.

The Saxophone Music of Pierre-Philippe Bauzin: A Survey of Original Compositions and Rediscovery of Lost Works

Description: Pierre-Philippe Bauzin (1933-2005) was a skilled keyboard performer, improviser, and composer. By way of his close personal friendship with renowned saxophonist Jean-Marie Londeix, Bauzin began dedicating, composing, and often times performing music for saxophone with Londeix, beginning in 1959. The results of this friendship produced eleven original works for saxophone with diverse instrumentation, ranging from solo compositions to large ensembles. Due to Bauzin's preference for improvising the piano accompaniments of his music on each performance, however, a majority of his compositions were thought to be incomplete or lost. This study surveys Bauzin's complete opus for saxophone by way of both his published works, and the author's rediscovery of the manuscripts to these previously assumed lost compositions for saxophone. The pieces studied are Sonata no. 1 (1959), Poème (1960), Cinq Pièces Breves en Forme de Musique (1960), Esquisses (1967), Divertimento (1968), and Quatuor no. 1 (1962). In addition, chapter 8 provides information regarding other compositions for saxophone by Bauzin that did not survive in their completed form. The survey of each work contains information pertaining to creation, performances of significance in saxophone history, and compositional techniques present within each work that can be used to identify the components of Bauzin's unique compositional style.

Enhancing Storage Dependability and Computing Energy Efficiency for Large-Scale High Performance Computing Systems

Description: With the advent of information explosion age, larger capacity disk drives are used to store data and powerful devices are used to process big data. As the scale and complexity of computer systems increase, we expect these systems to provide dependable and energy-efficient services and computation. Although hard drives are reliable in general, they are the most commonly replaced hardware components. Disk failures cause data corruption and even data loss, which can significantly affect system performance and financial losses. In this dissertation research, I analyze different manifestations of disk failures in production data centers and explore data mining techniques combined with statistical analysis methods to discover categories of disk failures and their distinctive properties. I use similarity measures to quantify the degradation process of each failure type and derive the degradation signature. The derived degradation signatures are further leveraged to forecast when future disk failures may happen. Meanwhile, this dissertation also studies energy efficiency of high performance computers. Specifically, I characterize the power and energy consumption of Haswell processors which are used in multiple supercomputers, and analyze the power and energy consumption of Legion, a data-centric programming model and runtime system, and Legion applications. We find that power and energy efficiency can be improved significantly by optimizing the settings and runtime scheduling of processors, and Legion runtime performs well for larger-scale computation in terms of power and energy consumption.

College and Career Readiness of Students with Autism

Description: With one in every 59 individuals now diagnosed with autism spectrum disorder (ASD), there is a significant increase in college enrollment for these students, yet, alarmingly, this population has the highest college dropout rate. Using Rawl's social justice theory as the frame, this qualitative study identified the perceptions of students with ASD, their college professors, and the director of the Office of Disability Accommodation (ODA). Perceptions were examined through open-ended surveys regarding awareness of autism, knowledge of student civil rights, and the availability and adequacy of resources provided through the ODA. In addition, the students with autism participated in semi-structured face-to-face interviews. The findings of this study are consistent with other studies in reflecting barriers experienced by students with ASD, such as poor transition planning, communication, and self-advocacy limitations. The variance among reported perceptions revealed a lack of awareness and continuity of resources and support for students with autism, hindering their successful transition from high school to and through post-secondary education. Both students and professors expressed a lack of knowledge of students' rights at the college level and of how to access needed accommodations. These findings reveal the need for a greater awareness of supports needed by students with ASD as they enter college. The findings provide implications for professionals who provide transition services for individuals with ASD.

Sing Rāga, Embody Bhāva: The Way of Being Rasa

Description: The rasa theory of Indian aesthetics is concerned with the nature of the genesis of emotions and their corresponding experiences, as well as the condition of being in and experiencing the aesthetic world. According to the Indian aesthetic theory, rasa ("juice" or "essence," something that is savored, that is tasted) is an embodied aesthetic experienced through an artistic performance. In this thesis, I have investigated how the aesthetics of rasa philosophy account for creative presence and its experiences in Karnatik vocal performances. Beyond the facets of grammar, Karnatik rāga performance signifies a deeper ontological meaning as a way to experience rasa, idiomatically termed as rāga-rasa by South Indian rāga practitioners. A vocal performance of a rāga ideally depends on a singer's embodied experience of rāga and rāga-bhāva (emotive expression of rāga), as much as it does on his/her theoretical knowledge and skillset of a rāga's svaras (scale degrees), gamakas (ornamentation), lakṣhaṇās (emblematic phrases), and so on. Reflecting on my own experience of being a Karnatik student and performer for the last two decades, participant observation, interviews, and analysis of Indian aesthetic theory of rasa, I propose a way of understanding that to sing rāga is to embody bhāva opening the space that brings rasa into being. Reflecting on the epistemology of rāga theory, particularly its smaller entities of svaras and gamakas, and through a phenomenological description of the process through which a vocalist embodies rāga (including how a guru transmits this musical embodiment to his shishya [disciple]), I argue that the notion of rāga-rasa itself has agency in determining the nature of svaras and its gamakas in a rāga performance. Additionally, focusing on the relationship between performers and rasikas (drinkers of the juice), this thesis examines how the embodiment of rāga-bhāva and the experience of rasa open the possibility for ...

A Data-Driven Computational Framework to Assess the Risk of Epidemics at Global Mass Gatherings

Description: This dissertation presents a data-driven computational epidemic framework to simulate disease epidemics at global mass gatherings. The annual Muslim pilgrimage to Makkah, Saudi Arabia is used to demonstrate the simulation and analysis of various disease transmission scenarios throughout the different stages of the event from the arrival to the departure of international participants. The proposed agent-based epidemic model efficiently captures the demographic, spatial, and temporal heterogeneity at each stage of the global event of Hajj. Experimental results indicate the substantial impact of the demographic and mobility patterns of the heterogeneous population of pilgrims on the progression of the disease spread in the different stages of Hajj. In addition, these simulations suggest that the differences in the spatial and temporal settings in each stage can significantly affect the dynamic of the disease. Finally, the epidemic simulations conducted at the different stages in this dissertation illustrate the impact of the differences between the duration of each stage in the event and the length of the infectious and latent periods. This research contributes to a better understanding of epidemic modeling in the context of global mass gatherings to predict the risk of disease pandemics caused by associated international travel. The computational modeling and disease spread simulations in global mass gatherings provide public health authorities with powerful tools to assess the implication of these events at a different scale and to evaluate the efficacy of control strategies to reduce their potential impacts.

Extracting Temporally-Anchored Spatial Knowledge

Description: In my dissertation, I elaborate on the work that I have done to extract temporally-anchored spatial knowledge from text, including both intra- and inter-sentential knowledge. I also detail multiple approaches to infer spatial timeline of a person from biographies and social media. I present and analyze two strategies to annotate information regarding whether a given entity is or is not located at some location, and for how long with respect to an event. Specifically, I leverage semantic roles or syntactic dependencies to generate potential spatial knowledge and then crowdsource annotations to validate the potential knowledge. The resulting annotations indicate how long entities are or are not located somewhere, and temporally anchor this spatial information. I present an in-depth corpus analysis and experiments comparing the spatial knowledge generated by manipulating roles or dependencies. In my work, I also explore research methodologies that go beyond single sentences and extract spatio-temporal information from text. Spatial timelines refer to a chronological order of locations where a target person is or is not located. I present corpus and experiments to extract spatial timelines from Wikipedia biographies. I present my work on determining locations and the order in which they are actually visited by a person from their travel experiences. Specifically, I extract spatio-temporal graphs that capture the order (edges) of locations (nodes) visited by a person. Further, I detail my experiments that leverage both text and images to extract spatial timeline of a person from Twitter.

The Power of Place: A Qualitative Evaluation of Stream Monitoring Data Usage by Decision-Makers in Dane County, WI

Description: Has years of citizen-based nutrient sampling and baseline water quality monitoring efforts only had a "trivial" impact on natural resource management decisions? This thesis will explore this and other findings from a qualitative evaluation of the Rock River Coalition (RRC) citizen-based stream monitoring project in Dane County, Wisconsin, USA. These findings are the culmination of 47 semi-structured interviews with decision-makers from seven client-identified categories and participant observations of board meetings and other watershed groups. Interview questions focused on current strategies of data design and dissemination with the goal of constructing a clearer picture of existing data usage by Dane County decision-makers. In the wider picture of citizen science and community-based research, this case study aims to highlight barriers to data use and potential solutions. The results of this case study were understood through four key frames: (1) Bourdieu's concept of symbolic capital, (2) Barzilai‐Nahon's theory of network gatekeeping, (3) Newman et al.'s framework for leveraging the power of place, and (4) a Foucauldian approach to the production of scientific knowledge. The findings of this study highlight the presence of gatekeeping mechanisms within the scientific field as well as government institutions, problematize the practice of placemaking, assert there is untapped symbolic capital to be wielded by citizen scientists, and trace the "innovation" of volunteer water monitoring data in Dane County.

Evaluating the Efficacy of Engagement Journalism in Local News: An Ethnographic Study of the "Dallas Morning News"

Description: The Dallas Morning News is a leader in using engagement journalism to increase and retain digital subscribers. This ethnography examined the efficacy of the engagement journalism work by the News in rebuilding trust and forming relationships with its audience. This research is exceptionally timely as more newsrooms are erecting paywalls to their content and asking their audiences to offer monetary support in exchange for greater access and engagement by journalists. This work is examined through two mass communications theories: functionalism, which says a society can be viewed like an ecosystem as a "system in balance" consisting of complex sets of interrelated activities, each of which supports the others in maintaining the system as a whole; and the dual responsibility model, which says that companies should operate in the best interests of all in the community who depend on them, not only those who benefit financially. Additionally, the work is considered from a human-interaction design standpoint to evaluate whether the News has created affordances that enable the journalists and the readers to communicate, and whether the journalists are effectively practicing service design when publishing news and information for the audience.

Assessing Program-Readiness for Dental/Medical Tolerance

Description: Many clients with developmental and/or intellectual disabilities (ID/DD) do not tolerate routine medical or dental procedures and may require intrusive interventions, including restraint of various types (i.e. chemical, mechanical, physical, etc.) during appointments. Graduated exposure, or stimulus fading, along with reinforcement for compliance, have been shown to increase cooperation and tolerance in some clients; however, many do not respond to these types of interventions. Nine participants diagnosed with ID/DD recieved compliance/tolerance training for routine medical or dental procedures. Results of these interventions were evaluated in the context of several potential indices of readiness, such as medical diagnoses, level of disability, and presence of challenging behavior, among others. Several of the variables appeared to be correlated with program responsiveness; however, a larger sample will be necessary to draw definitive conclusions. Client characteristics and past assessments (anecdotals, preference assessments, terminal probes, and survey data) were evaluated. The analytical framework developed for this analysis may be useful to future researchers and clinicians as a model for assessing readiness for tolerance training programs.

An Overview and Performance Guide to Johannes Möller's "Shenandoah Fantasy for Two Guitars"

Description: Johannes Möller's 2014 composition Shenandoah Fantasy for Two Guitars, is a theme and variations on the American folksong Oh Shenandoah and is the composer's only work dedicated to American music. An informed performance of this work requires biographical information. Since no scholarly work on this composer is currently available, this paper includes Möller's biographical information, compositional background and performance suggestions. This information was acquired through a recorded video interview with the composer that covered his early education as a guitarist and composer, his formal conservatory training, career accomplishments, influences that informed the piece, and suggestions for performance practice. The insight gained through this interview reveals its main influences as the Romantic Fantasy, American Minimalism, Keith Jarret's harmonization of Oh Shenandoah, American country and bluegrass music, and the sounds of American folk instruments. These are the subjects of the body of this paper. In addition to an overview of some scholarly writing on the styles which influence the piece, some solutions are offered at the end of the paper to aid in the performance of difficult passages. The intent of these solutions is to make the piece easier for the left and right hand, without sacrificing those musical elements that represent its influences. This is currently the only scholarly work available for Shenandoah Fantasy for Two Guitars and its composer.

Practical Considerations for Euphonium Players Doubling on Tuba

Description: There is currently a great deal of information available to euphonium players who double on trombone, but far less for euphonium players who double on tuba. This dissertation takes information gathered from many top euphonium/tuba doublers, including: Benjamin Pierce, D.M.A., Aaron Tindall, D.M.A., Gail Robertson, D.M.A., Gretchen Renshaw James, D.M.A., Matthew Murchison, D.M.A., Matthew Shipes, D.M.A., Matthew Tropman, D.M.A., and Keith Kile, and presents a synopsis of their thoughts/reflections on tuba doubling. This dissertation is designed to aide euphonium players in the process of learning tuba, enabling them to be as efficient as possible with both their time and money throughout the process. Topics covered include: difficulties unique to the euphonium/tuba double and approaches to overcome them, similarities and differences between euphonium and tuba playing (from the perspective of euphonium/tuba doublers), "reverse" benefits of euphonium/tuba doubling on the primary instrument, literature recommendations for euphonium/tuba doublers, and equipment considerations for euphonium/tuba doublers.

Poor Things: Objects, Ownership, and the Underclasses in American Literature, 1868-1935

Description: This dissertation explores both the production of underclass literature and the vibrancy of material between 1868-1935. During an era of rampant materialism, consumer capitalism, unchecked industrialism, and economic inequality in the United States, poor, working class Americans confronted their socioeconomic status by abandoning the linear framework of capitalism that draws only a straight line between market and consumer, and engaging in a more intimate relationship with local, material things – found, won, or inherited – that offered a sense of autonomy, belonging, and success. The physical seizure of property/power facilitated both men and women with the ability to recognize their own empowerment (both as individuals and as a community) and ultimately resist their marginalization by leveling access to opportunity and acquiring or creating personal assets that could be generationally transferred as affirmation of their family's power and control over circumstance. Reading into these personal possessions helps us understand the physical and psychological conflicts present amongst the underclasses as represented in American literature, and these conflicts give rise to new dynamics of belonging as invested in the transformative experience of ownership and exchange. If we can understand these discarded, poor, and foreign things and people as possessing dynamic and vibrant agency, then we will change the ethics of objectifying and ostracizing discarded, poor, and foreign humans, then and now.

Isolation and Bioinformatic Characterization of Four Novel Bacteriophages from Streptomyces toxytricini

Description: Six initial phage isolates with high titer lysates were obtained using Streptomyces toxytricini B-5426 as the host bacterium. These isolates were named Goby, Toma, Yosif, Yara, Deema, and Hsoos. However, upon completion of the sequencing, it was found that the Yara and Hsoos isolates were identical, as were Goby and Deema. As a result, final analysis was completed on only the four unique isolates. All of the phages mentioned above were isolated from soil samples from different locations. Also, they had different sizes of plaques, ranging from 0.3 – 0.9mm. Yosif had the largest plaque size. Yara's head diameter was 79nm with tail diameter of 94nm.

Denim Fiberboard Fabricated from MUF and pMDI Hybrid Resin System

Description: In this study, a series of denim fiberboards are fabricated using two different resins, malamine urea formaldehyde (MUF) and polymeric methylene diphenyl diisocyanate (pMDI). Two experimental design factors (1) adhesive content and (2) MUF-pMDI weight ratio, were studied. All the denim fiberboard samples were fabricated following the same resin blending, cold-press and hot-press procedures. The physical and mechanical tests were conducted on the fiberboard following the procedures described in ASTM D1037 to obtain such as modulus of elasticity (MOE), modulus of rupture (MOR), internal bond (IB), thickness swell (TS), and water absorption (WA). The results indicated that the MOE was significantly affected by both factors. IB was affected significantly by weight ratio of different glue types, with 17 wt% more MDI resin portion in the core layer of the denim boards, the IB for total adhesive content 15% fiberboard was enhanced by 306%, while for total adhesive content 25% fiberboard, enhanced by 205%. TS and WA, with higher adhesive content used in denim boards' fabrication, and more pMDI portion in the core layer of the boards, the boards' TS and WA was reduced by up to 64.2% and 78.8%, respectively.

Transhumanism: An Ontology of the World's Most Dangerous Idea

Description: Transhumanism is the name given to the cultural and philosophical movement which advocates radical human technological enhancement. In what follows, I use perspectives drawn from existential philosophy to problematize transhumanists' desire to recast human finitude as a series of technical problems with technical solutions. The ontological account of transhumanism offered here questions the assumed benefit and inevitability across six chapters. Following an introductory chapter, Chapter 2 introduces the key players, and present the philosophy of transhumanism and the opposing view of bioconservativism. Chapter 3 offers a narrative of transhumanism beginning with its mythical antecedents, and proceeds to describe the emergence of contemporary transhumanist institutions. Chapter 4 focuses on the challenge that transhumanists Aubrey de Grey and Ray Kurzweil present to mortality. The chapter asks whether human immortality is a coherent idea, and consider the consequences of achieving a data-driven amortality. Chapter 5 continues the analysis of transhumanism as it challenges limits to knowledge (ignorance), and limits to well-being (suffering). Ray Kurzweil is presented as a key figure of transhumanist thought, along with David Pearce, who desires to eradicate suffering through genetic engineering. The hubris of transhumanism is viewed through the lens of Friedrich Nietzsche in chapter 6. Nietzsche's critique of the "last human" is interpreted in terms of transhumanist thought, and a role for the philosopher in the context of transhumanism is presented. Finally, chapter 7 offers Buddhism as an alternative response to suffering. This chapter profiles "Buddhist Transhumanists," and consider what connection transhumanism has with Buddhism's philosophy of impermanence.
