Bayesian phylogenetics illuminate shallower relationships among Trans-Himalayan languages in the Tibet-Arunachal area

Kho-Bwa, Hrusish, Mishmic, Tani, and Tshangla are language clusters that have been recurrently proposed as subgroups of the Trans-Himalayan (also known as Tibeto-Burman and Sino-Tibetan) language family. Nonetheless, their internal classification, as well as the relation with each other and with other linguistic groups in the family, is hitherto unresolved. We use lexical data on these groups and dated phylogenies to investigate such internal classifications.We base our examination on previous research into the language family in the Tibet-Arunachal area, and follow a computer -assisted approach of language comparison to perform Bayesian phylolinguistic analysis. As earlier phylogenetic studies on this family included little data related to this geographic area, we took a subset of the best available dataset and extended it with vocabularies for the Kho-Bwa and Hrusish clusters, also including one Mishmic, two Tani, twoTshangla, and five East Bodish languages to cover the major languages and linguistic subgroups neighboring these clusters. Our results shed light on the internal and external classification of the Kho-Bwa, Hrusish and Bodish languages, and allow us to share valuable experience on theextent to which similar approaches can be applied to the phylogenetic analysis of the Trans-Himalayan language family

Contextualizing the Writings of J.R.R. Tolkien on Literary Criticism

This essay offers a reinterpretation of Tolkien\u27s writings about literary criticism, which are focused on Beowulf, fairy stories, and his own works. Whereas his writings have often been taken to mean that analytic scholarship is not valid and should not be pursued, my essay takes the intellectual climate of the time into consideration and offers an alternative interpretation, according to which he did not mean to forbid these studies outright and indeed intended that scholars should continue writing them. The essay ends with a call to academics not to be discouraged by his strong language from producing analytic studies

The Effects of Western Medicine on the Livelihood of Zulu Traditional Herbal Healers in South Africa

The majority of South African citizens experience inadequate healthcare due to underfunding, mismanagement, staff shortages, and infrastructure problems. Before a healthcare system was created, the sick turned to traditional herbal healers for care. South Africa’s Zulu healers possess specialized knowledge of local plants and medicine thought to have physical and spiritual healing properties. The country’s increasing reliance on Western biomedicine has created a current concern from indigenous medicine conservationists regarding the future of this kind of knowledge. In order to assess the effects of Western medicine on traditional healing practices, I collected data on the various uses of traditional medicine, the frequency in which it is used relative to Western medicine, and how it is maintained in the community. The data identified the various uses and potential problems of Western medicine and Zulu traditional herbal practice in helping the community. The traditional herbal healers revealed close connections between the informational, spiritual, physical, and cultural components of the practice that characterize its livelihood and practice for generations to come. This information allows for a greater understanding of how culture and medicinal knowledge can be entwined together and the positive or negative effects of biomedicine interacting with traditional medicine to help solve sicknesses in not only South Africa, but potentially in our global community

Dying the Good Death: Cultural Competence and Variance in Hospice Care

This paper examines the intersections between death and culture in the context of hospice care. The patient demographics of modern hospice care are overwhelmingly White; through an analysis of the formation of Korean-American culture and its distinct values, I conclude that hospice as we know it today primarily adheres to the Western conceptualization of a “good death”, and therefore is not accessible to those who belong to different cultures. In order to remedy this and to explain the racial disparities among hospice patients, I apply a model of cultural competency that specifically caters to Korean-American death traditions. While the effects of implementation are unknown, this model reimagines hospice to be a critical nexus between cultural variance and a good death

Information-theoretic causal inference of lexical flow

This volume seeks to infer large phylogenetic networks from phonetically encoded lexical data and contribute in this way to the historical study of language varieties. The technical step that enables progress in this case is the use of causal inference algorithms. Sample sets of words from language varieties are preprocessed into automatically inferred cognate sets, and then modeled as information-theoretic variables based on an intuitive measure of cognate overlap. Causal inference is then applied to these variables in order to determine the existence and direction of influence among the varieties. The directed arcs in the resulting graph structures can be interpreted as reflecting the existence and directionality of lexical flow, a unified model which subsumes inheritance and borrowing as the two main ways of transmission that shape the basic lexicon of languages. A flow-based separation criterion and domain-specific directionality detection criteria are developed to make existing causal inference algorithms more robust against imperfect cognacy data, giving rise to two new algorithms. The Phylogenetic Lexical Flow Inference (PLFI) algorithm requires lexical features of proto-languages to be reconstructed in advance, but yields fully general phylogenetic networks, whereas the more complex Contact Lexical Flow Inference (CLFI) algorithm treats proto-languages as hidden common causes, and only returns hypotheses of historical contact situations between attested languages. The algorithms are evaluated both against a large lexical database of Northern Eurasia spanning many language families, and against simulated data generated by a new model of language contact that builds on the opening and closing of directional contact channels as primary evolutionary events. The algorithms are found to infer the existence of contacts very reliably, whereas the inference of directionality remains difficult. This currently limits the new algorithms to a role as exploratory tools for quickly detecting salient patterns in large lexical datasets, but it should soon be possible for the framework to be enhanced e.g. by confidence values for each directionality decision

A computer-assisted pproach to the comparison of mainland southeast Asian languages

This cumulative thesis is based on three separate projects based on a computer-assisted language comparison (CALC) framework to address common obstacles to studying the history of Mainland Southeast Asian (MSEA) languages, such as sparse and non-standardized lexical data, as well as an inadequate method of cognate judgments, and to provide caveats to scholars who will use Bayesian phylogenetic analysis. The first project provides a format that standardizes the sound inventories, regulates language labels, and clarifies lexical items. This standardized format allows us to merge various forms of raw data. The format also summarizes information to assist linguists in researching the relatedness among words and inferring relationships among languages. The second project focuses on increasing the transparency of lexical data and cognate judg- ments with regard to compound words. The method enables the annotation of each part of a word with semantic meanings and syntactic features. In addition, four different conversion methods were developed to convert morpheme cognates into word cognates for input into the Bayesian phylogenetic analysis. The third project applies the methods used in the first project to create a workflow by merging linguistic data sets and inferring a language tree using a Bayesian phylogenetic algorithm. Further- more, the project addresses the importance of integrating cross-disciplinary studies into historical linguistic research. Finally, the methods we proposed for managing lexical data for MSEA languages are discussed and summarized in six perspectives. The work can be seen as a milestone in reconstructing human prehistory in an area that has high linguistic and cultural diversity
