Serving to secure "Global Korea": Gender, mobility, and flight attendant labor migrants
This dissertation is an ethnography of mobility and modernity in contemporary South Korea (the Republic of Korea) following neoliberal restructuring precipitated by the Asian Financial Crisis (1997). It focuses on how comparative âservice,â âsecurity,â and âsafetyâ fashioned âGlobal Koreaâ: an ongoing state-sponsored project aimed at promoting the economic, political, and cultural maturation of South Korea from a once notoriously inhospitable, âbackwardâ country (hujinâguk) to a now welcoming, âadvanced countryâ (sĆnjinâguk). Through physical embodiments of the culturally-specific idiom of âsuperiorâ service (sĆbisĆ), I argue that aspiring, current, and former Korean flight attendants have driven the production and maintenance of this national project.
More broadly, as a driver of this national project, this occupation has emerged out of the countryâs own aspirational flights from an earlier history of authoritarian rule, labor violence, and xenophobia. Against the backdrop of the Korean stateâs aggressive neoliberal restructuring, globalization efforts, and current âHell Chosunâ (HelchosĆn) economy, a group of largely academically and/or class disadvantaged young women have been able secure individualized modes of pleasure, self-fulfillment, and class advancement via what I deem âservice mobilities.â Service mobilities refers to the participation of mostly women in a traditionally devalued but growing sector of the global labor market, the âpink collarâ economy centered around âfeminineâ care labor. Korean female flight attendants share labor skills resembling those of other foreign labor migrants (chiefly from the âGlobal Southâ), who perform care work deemed less desirable. Yet, Korean female flight attendants elude the stigmatizing, classed, and racialized category of âlabor migrant.â Moreover, within the context of South Koreaâs unique history of rapid modernization, the flight attendant occupation also commands considerable social prestige.
Based on ethnographic and archival research on aspiring, current, and former Korean flight attendants, this dissertation asks how these unique care laborers negotiate a metaphorical and literal series of sustained border crossings and inspections between Korean flight attendantsâ contingent status as lowly care-laboring migrants, on the one hand, and ostensibly glamorous, globetrotting elites, on the other. This study contends the following: first, the flight attendant occupation in South Korea represents new politics of pleasure and pain in contemporary East Asia. Second, Korean female flight attendantsâ enactments of soft, sanitized, and glamorous (hwaryĆhada) service help to purify South Koreaâs less savory past. In so doing, Korean flight attendants reconstitute the historical role of female laborers as burden bearers and caretakers of the Korean state.U of I OnlyAuthor submitted a 2-year U of I restriction extension request
Bayesian networks for disease diagnosis: What are they, who has used them and how?
A Bayesian network (BN) is a probabilistic graph based on Bayes' theorem,
used to show dependencies or cause-and-effect relationships between variables.
They are widely applied in diagnostic processes since they allow the
incorporation of medical knowledge to the model while expressing uncertainty in
terms of probability. This systematic review presents the state of the art in
the applications of BNs in medicine in general and in the diagnosis and
prognosis of diseases in particular. Indexed articles from the last 40 years
were included. The studies generally used the typical measures of diagnostic
and prognostic accuracy: sensitivity, specificity, accuracy, precision, and the
area under the ROC curve. Overall, we found that disease diagnosis and
prognosis based on BNs can be successfully used to model complex medical
problems that require reasoning under conditions of uncertainty.Comment: 22 pages, 5 figures, 1 table, Student PhD first pape
Chitosan oligosaccharide as a plant immune inducer on the Passiflora spp. (passion fruit) CMV disease
Cucumber mosaic virus (CMV), one of the main viruses, is responsible for Passiflora spp. (passion fruit) virus diseases, which negatively affect its planting, cultivation, and commercial quality. In this study, a laboratory anti-CMV activity screening model for Passiflora spp. CMV disease was first established. Then, the effects of different antiviral agents of chitosan oligosaccharide (COS), dufulin (DFL), and ningnanmycin (Ning) on CMV virulence rate in Passiflora spp. were determined. The virulence rate and anti-CMV activity in Passiflora spp. treated with COS were 50% and 45.48%, respectively, which were even better than those of DFL (66.67% and 27.30%, respectively) and Ning (83.30% and 9.17%, respectively). Field trials test results showed COS revealed better average control efficiency (47.35%) against Passiflora spp. CMV disease than those of DFL (40.93%) and Ning (33.82%), indicating that COS is effective in the control of the Passiflora spp. CMV disease. Meanwhile, the nutritional quality test results showed that COS could increase the contents of soluble solids, titratable acids, vitamin C, and soluble proteins in Passiflora spp. fruits as well as enhance the polyphenol oxidase (PPO), superoxide dismutase (SOD), and peroxidase (POD) activity in the leaves of Passiflora spp. seedlings. In addition, the combined transcriptome and proteome analysis results showed that COS mainly acted on the Brassinosteroids (BRs) cell signaling pathway, one of plant hormone signal transduction pathway, in Passiflora spp., thus activating the up-regulated expression of TCH4 and CYCD3 genes to improve the resistance to CMV disease. Therefore, our study results demonstrated that COS could be used as a potential plant immune inducer to control the Passiflora spp. CMV disease in the future

Ten Quick Tips for Harnessing the Power of ChatGPT/GPT-4 in Computational Biology
The rise of advanced chatbots, such as ChatGPT, has sparked curiosity in the
scientific community. ChatGPT is a general-purpose chatbot powered by large
language models (LLMs) GPT-3.5 and GPT-4, with the potential to impact numerous
fields, including computational biology. In this article, we offer ten tips
based on our experience with ChatGPT to assist computational biologists in
optimizing their workflows. We have collected relevant prompts and reviewed the
nascent literature in the field, compiling tips we project to remain pertinent
for future ChatGPT and LLM iterations, ranging from code refactoring to
scientific writing to prompt engineering. We hope our work will help
bioinformaticians to complement their workflows while staying aware of the
various implications of using this technology. Additionally, to track new and
creative applications for bioinformatics tools such as ChatGPT, we have
established a GitHub repository at
https://github.com/csbl-br/awesome-compbio-chatgpt. Our belief is that ethical
adherence to ChatGPT and other LLMs will increase the efficiency of
computational biologists, ultimately advancing the pace of scientific discovery
in the life sciences.Comment: 14 pages, 1 figur
A Survey on Biomedical Text Summarization with Pre-trained Language Model
The exponential growth of biomedical texts such as biomedical literature and
electronic health records (EHRs), provides a big challenge for clinicians and
researchers to access clinical information efficiently. To address the problem,
biomedical text summarization has been proposed to support clinical information
retrieval and management, aiming at generating concise summaries that distill
key information from single or multiple biomedical documents. In recent years,
pre-trained language models (PLMs) have been the de facto standard of various
natural language processing tasks in the general domain. Most recently, PLMs
have been further investigated in the biomedical field and brought new insights
into the biomedical text summarization task. In this paper, we systematically
summarize recent advances that explore PLMs for biomedical text summarization,
to help understand recent progress, challenges, and future directions. We
categorize PLMs-based approaches according to how they utilize PLMs and what
PLMs they use. We then review available datasets, recent approaches and
evaluation metrics of the task. We finally discuss existing challenges and
promising future directions. To facilitate the research community, we line up
open resources including available datasets, recent approaches, codes,
evaluation metrics, and the leaderboard in a public project:

Categories and foundational ontology: A medieval tutorial
Foundational ontologies, central constructs in ontological investigations and engineering alike, are based on ontological categories. Firstly proposed by Aristotle as the very ur- elements from which the whole of reality can be derived, they are not easy to identify, let alone partition and/or hierarchize; in particular, the question of their number poses serious challenges. The late medieval philosopher Dietrich of Freiberg wrote around 1286 a tutorial that can help us today with this exceedingly difficult task. In this paper, I discuss ontological categories and their importance for foundational ontologies from both the contemporary perspective and the original Aristotelian viewpoint, I provide the translation from the Latin into English of Dietrich's De origine II with an introductory elaboration, and I extract a foundational ontologyâthat is in fact a single-category oneâfrom this text rooted in Dietrich's specification of types of subjecthood and his conception of intentionality as causal operation
Ontological Solutions to the Problem of Induction
The idea of the uniformity of nature, as a solution to the problem of induction, has at least two contemporary versions: natural kinds and natural necessity. Then there are at least three alternative ontological ideas addressing the problem of induction. In this paper, I articulate how these ideas are used to justify the practice of inductive inference, and compare them, in terms of their applicability, to see whether each of them is preferred in addressing the problem of induction. Given the variety of contexts in which inductive inferences are made, from natural science to social science and to everyday thinking, I suggest that no singular idea is absolutely preferred, and a proper strategy is probably to welcome the plurality of ideas helpful to induction, and to take pragmatic considerations into account, in order to judge in every single case
Animating potential for intensities and becoming in writing: challenging discursively constructed structures and writing conventions in academia through the use of storying and other post qualitative inquiries
Written for everyone ever denied the opportunity of fulfilling their academic potential, this is âChloeâs storyâ. Using composite selves, a phrase chosen to indicate multiplicities and movement, to story both the initial event leading to âChloeâsâ immediate withdrawal from a Further Education college and an imaginary second chance to support her whilst at university, this Deleuzo-Guattarian (2015a) âassemblageâ of post qualitative inquiries offers challenge to discursively constructed structures and writing conventions in academia. Adopting a posthuman approach to theorising to shift attention towards affects and intensities always relationally in action in multiple âassemblagesâ, these inquiries aim to decentre individual âlecturerâ and âstudentâ identities. Illuminating movements and moments quivering with potential for change, then, hoping thereby to generate second chances for all, different approaches to writing are exemplified which trouble those academic constraints by fostering inquiry and speculation: moving away from âwhat isâ towards âwhat ifâ.
With the formatting of this thesis itself also always troubling the rigid Deleuzo-Guattarian (2015a) âsegmentary linesâ structuring orthodox academic practice, imbricated in these inquiries are attempts to exemplify Manningâs (2015; 2016) âartfulnessâ through shifts in thinking within and around an emerging PhD thesis. As writing resists organising, the verb thesisising comes into play to describe the processes involved in creating this always-moving thesis. Using âlanding sitesâ (Arakawa and Gins, 2009) as a landscaping device, freely creating emerging âlines of flightâ (Deleuze and Guattari, 2015a) so often denied to students forced to adhere to strict academic conventions, this âmovement-movingâ (Manning, 2014) opens up opportunities for change as in Manningâs (2016) âresearch-creationâ. Arguing for a moving away from writing-representing towards writing-inquiring, towards a writing âthat doesâ (Wyatt and Gale, 2018: 127), and toward writing as immanent doing, it is hoped to animate potential for intensities and becoming in writing, offering opportunities and glimmerings of the not-yet-known
A Framework Proposal to Evaluate Conceptual Models Framing Wicked Managerial Concepts
Visual and collaborative canvases named visual inquiry tools have emerged as a powerful design science research (DSR) artefact to address wicked managerial problems. According to the design theory for visual inquiry tools, designing such a tool entails the development of a particular type of conceptual model, namely a parsimonious and simple conceptual model. Although the theory lists design principles that the conceptual model must abide by, it unfortunately remains silent regarding how one evaluates it in regard to them. Given that, coupled with the fundamental position evaluation holds in DSR, this research paper builds on existing prescriptive knowledge to develop a framework that supports designers in the evaluation of their conceptual model. The framework is composed of four evaluands, evaluation criteria, and guiding questions which depict, at a high-level, the questions to ask to evaluate the conceptual model. The framework is then applied to evaluate an existing conceptual model
