Applying deep learning for cell detection in time-lapse microscopic images
Get PDFThe budding yeast Saccharomyces cerevisiae is an effective model for studying cellular aging. We can measure the lifespan of yeast cells in two ways: replicative and chronological lifespans. Chronological focuses on the time that a cell can survive. The replicative lifespan (RLS) is the number of cell divisions that a single mother cell can go through before ceases to be dividing. RLS is a measurement of individual cells and is more informative on the aging process than in chronological lifespan. Many genes that influence yeast RLS have been shown to be highly conserved and have a similar effect on aging in humans. Hence, studies on cellular aging typically focus on RLS. RLS is traditionally measured by micro-dissection – a tedious and time-consuming process. Recently, a high-throughput yeast aging analysis (HYAA) based on microfluidics measurement of replicative aging has been developed. Each mother cell is captured by a trap on the microfluidic device. This device generates an enormous amount of dataset, but the process to manually track these objects is tedious and time consuming and would take years with how large a single dataset can be. This thesis is to address the challenges on how to efficiently and reliably infer the RLS from thousands of time-lapse microscopic images. We implemented two deep learning methods, Faster R-CNN and MASK R-CNN to detect cell the objects. Our results show that Mask R-CNN is a promising method to automate the HYAA image analysis compared to Faster R-CNN approach
A retrospective investigation of racial-ethnic socialization
Get PDFRacial and ethnic socialization is the way in which parents teach their children about race and ethnicity and it occurs in all families in varying forms. Unlike many white families, those of racial minorities tend to take an approach that makes their children aware of their race and its social implications. The present research project investigated the racial-ethnic socialization methods of Americans from varying racial and ethnic backgrounds to identify similarities and differences. This research analyzed the surveys of 52 parents and 32 nonparents in order to examine generational similarities and differences of race talk. Parents of color were more likely to embrace color conscious methods of race talk than White parents who were more likely to embrace color blind methods. Additionally, race talk did change from one generation to the next. Overall, the sample from this study indicated a high level of comfort with racial discourse which may be an important factor. All in all, race and parent status seemed to have significant effects. Findings from this study can be used to further investigate the content and context of race talk between parent and child
Cancel culture: posthuman hauntologies in digital rhetoric and the latent values of virtual community networks
Get PDFThis study explores how modern epideictic practices enact latent community values by analyzing modern call-out culture, a form of public shaming that aims to hold individuals responsible for perceived politically incorrect behavior via social media, and cancel culture, a boycott of such behavior and a variant of call-out culture. As a result, this thesis is mainly concerned with the capacity of words, iterated within the archive of social media, to haunt us—both culturally and informatically. Through hauntology, this study hopes to understand a modern discourse community that is bound by an epideictic framework that specializes in the deconstruction of the individual’s ethos via the constant demonization and incitement of past, current, and possible social media expressions. The primary goal of this study is to understand how these practices function within a capitalistic framework and mirror the performativity of capital by reducing affective human interactions to that of a transaction
Motivational contagion in a leader-follower dynamic
Get PDFMotivational contagion is a process where one individual’s intentions are adopted by others (Dragoni & Kuenzi, 2012). Leaders enact motivational contagion when they share their goal orientations with followers. The present work proposes applying motivational contagion to a leader-follower dynamic to identify how it occurs and if substitutes/neutralizers to leadership reduce the rates of motivational contagion. Data from 300 followers will be collected using MTurk. It is hypothesized that motivational contagion occurs because leaders behaviorally establish and reinforce a desired climate that signals similar goal orientations in followers. The presence of substitutes/neutralizers to leadership are hypothesized to reduce the rates of motivational contagion. A potential theoretical implication of this research is a fuller explicative understanding of motivational contagion’s process between leaders and followers. A potential practical implication is behavioral guidance for leaders to share a desired goal orientation with followers for stronger work group effectiveness
Application of reduced order modeling for simulation of turbulent combustion
Get PDFReduced-order modeling (ROM) in the context of large-eddy simulation (LES) presents a computationally efficient and accurate strategy for simulation-based design studies. In this talk, application of a Galerkin projection-based ROM strategy to perform LES of a freely propagating methane/air turbulent premixed flame will be presented. The projection approach utilizes spatially varying proper orthogonal decomposition (POD) based modes obtained from a reference simulation as basis functions and solves for the time-dependent coefficients of the corresponding basis functions to obtain the solution. Since chemically reacting turbulent flows are governed by nonlinear system of equations, therefore, only employing a projection approach does not reduce the overall computational complexity. This is addressed by using the discrete empirical interpolation method (DEIM). The two ROM strategies, referred to as POD and POD-DEIM, are evaluated for their ability in predicting structural and statistical features of a freely propagating turbulent premixed flame
Literature review of the relationship between illness identity and recovery outcomes among adults with severe mental illness
Get PDFThis paper is a literature review of the relationship between illness identity and recovery outcomes among adults with severe mental illness. First, illness identity is explored as presented in the literature, through analysis of work on narrativization, labeling theory and the role of gender stereotypes. Literature on stigmatization as a mediating factor that influences the ways illness identity impacts recovery is also studied. Finally, work is presented on recovery outcomes that are a direct result of self-perception. Findings suggest the existence of two paradigms; positive and negative illness identity as the result of mediating factors from the diagnosis stage. A rough model of the process of recovery vis-a-vis illness identity is, therefore, suggested and the implications of discoveries of the current literature on clinical practice are outlined
George Berkeley\u27s idealism: an examination of the idealist metaphysics and its connection to philosophy of mind
Get PDFThe prominent 18th century empirical philosopher George Berkeley espoused a philosophy known as “idealism.” This thesis aims to show that George Berkeley’s idealism is a formidable player in philosophy of mind. The present research unfolds his arguments for idealism as they appear in A Treatise Concerning the Principles of Human Knowledge, turning at several points to The Three Dialogues between Hylas and Philonous for clarification. This research further explores the fundamentals of idealism in light of philosophy of mind, highlighting idealism’s intrinsic connection to this discipline. While this work is far from exhaustive, it provides the reader with essential information on Berkeley’s idealism and proves its worth as a philosophy in today’s world
