The phonetics and phonology of coronal markedness and unmarkedness

Thesis (Ph.D.)--Massachusetts Institute of Technology, Dept. of Linguistics and Philosophy, 2000.Includes bibliographical references (p. 191-202).This thesis investigates place feature restrictions in oral and nasal stop consonants with a special focus on the asymmetrical behavior of coronal and noncoronal stops. Two conflicting patterns of place restriction in outputs are attested: coronal unmarkedness and coronal markedness. This thesis shows that coronal unmarkedness is truly a default pattern of place restriction. Coronal unmarkedness is not confined to specific segmental contexts or to languages with a particular inventory structure. In addition, the coronal unmarked pattern is attested through diverse phonological processes such as assimilation, place neutralization, segmental and featural deletion, metathesis, vowel syncope and morpheme structure constraints. This follows from the context-free place markedness hierarchy proposed by Prince and Smolensky (1993). These constraints can conjoin freely with any context-specific constraints. Such conjunction predicts neutralization to coronal place to be attested in any position where place contrast reduction is found. On the other hand, although coronal markedness is also attested through diverse phonological processes such as assimilation, place neutralization, segmental and featural deletion, metathesis and morpheme structure constraints, it is found only in nonprevocalic positions and only in languages without a sub-coronal place contrast. I propose that unlike the default markedness constraint hierarchy, the reversed markedness hierarchy is projected from a perceptibility scale of place features and is therefore context-specific. I argue that a coronal stop in nonprevocalic position in a single-coronal language is perceptually less salient than noncoronal stops in corresponding positions due to a preferential weakening of tongue body articulation for coronal stops in these positions. Also discussed in this thesis is the effect of nasality of stops on the degree of place restrictions. A nasal stop tends to allow fewer place contrasts than an oral stop and a stop followed by an oral stop tends to allow fewer place contrasts than one followed by a nasal stop. Finally, previous approaches to coronal versus noncoronal asymmetry-Coronal Underspecification, Underspecification by Constraints and Perceptually Grounded Faithfulness Constraints are discussed and their inadequacy is demonstrated.by Yoonjung Kang.Ph.D

The Effects of Phonetic Duration on Loanword Adaptation: Mandarin Falling Diphthong in Chinese Korean

This study examines how Mandarin falling sonority diphthongs are adapted to a Chinese Korean dialect. It investigates how the subtle phonetic conditions of the source language affect adaptation, and if and how those phonetic effects differ in established loanwords compared to the on-line adaptation of novel loan forms. We found that in this bilingual population, while the Mandarin diphthongs are usually adapted as monophthongs, obeying the native phonological restriction against falling diphthongs, the retention of the input diphthongs in violation of the native constraint is also quite common. Additionally, we found that the choice of the monophthong vs. diphthong realization is strongly affected by the input phonetic duration and in particular, the durational difference among the different tones is robustly reflected in the adaptation patterns.The authors would like to thank three anonymous reviewers for their suggestions that improved the paper.

Effect of Exercise Intervention on Flow-Mediated Dilation in Overweight and Obese Adults: Meta-Analysis

The objective of this meta-analysis is to summarize the effect of exercise intervention on flow-mediated dilatation (FMD) in overweight and obese adults. We searched four electronic databases (PubMed/Medline, Scopus, and CINAHL) through June 2016 for relevant studies pertaining to the effectiveness of exercise intervention on FMD. Seventeen of the 91 studies identified met the inclusion criteria. Comprehensive Meta-Analysis software (version 3) was used to compute the standardized mean difference effect size (ES) and 95% CI using a random effects model. We calculated 34 ESs. We found that exercise intervention had medium and positive effects on FMD, with an overall ES of 0.522 (95% CI = 0.257, 0.786). Heterogeneity of ESs was observed ( = 239, ≤ 0.001, 2 = 86.19), and the effect was moderated by comorbidity ( = 6.39, df = 1, = 0.011). A large ES for the combination exercise, low intensity exercise, and comorbidity subgroups (ES = 0.82∼1.24) was found. We conclude that while exercise intervention significantly improves FMD in overweight and obese adults, the effect may depend on the different characteristics of exercise intervention and on participants’ demographics

French loanwords in Vietnamese: the role of input language phonotactics and contrast in loanword adaptation

This study examines the adaptation of French vowels in Vietnamese focusing on adaptation patterns that seem to defy a straightforward analysis based on native phonotactic restrictions or comparison of phonetic input-output similarity. A proper analysis requires reference to knowledge of the input language phonology. In the first case study, we observe that Vietnamese adapters extend the French phonotactic tendencies, i.e., Loi de Position, to loan adaptation productively. Such "intrusion" of L2 phonology knowledge may arise when phonetics underdetermines the adaptation and the adapters look to their knowledge of L2 phonology to arrive at adaptation. It is also notable that the L2 knowledge employed in adaptation is not native-like as the adaptation is not always isomorphic to the French input. In the second case study, the contrast of L2 phonology is neutralized due to an L1 phonological restriction but the Vietnamese adaptation systematically retains the contrast in the quality and length difference in the preceding vowel. There is plausible phonetic motivation for this adaptation pattern, but phonetically faithful mapping underdetermines the attested adaptation pattern, and reference to knowledge of L2 phonological contrasts is necessary. These findings illustrate the complexity of the loanword adaptation process, where a variety of different factors including L1 phonological restrictions, phonetic similarity, and L2 phonological knowledge, interact to affect adaptation

Association of Cholesterol Granuloma and Aspergillosis in the Sphenoid Sinus

Cholesterol granuloma (CG) is usually associated with chronic middle ear disease, and is not common in the paranasal sinuses. Additionally, it is very rare for cases of CG to be associated with a fungal infection. However, in this paper, we report a case of sphenoid sinus CG that is associated with aspergilloma in a 78-year-old male patient who presented with right hemifacial pain, headache and toothache. CT revealed the presence of an expansile cystic mass lesion in the sphenoid sinus that showed a high signal intensity on both the T1 and T2 weighted images. This mass was later determined to be CG. The suspected etiologic mechanisms of both CG and aspergilloma of the paranasal sinuses are similar, and impaired drainage and obstruction of the ventilation of the paranasal sinuses are considered to be the causative mechanism of both diseases. Overall, the results of this study indicate that the use of MRI findings could be helpful for differentiating CG from other paranasal sinus mass lesions

Contemporary Utilization and Outcomes of Resuscitative Endovascular Balloon Occlusion of the Aorta for Traumatic Noncompressible Torso Hemorrhage in Korea: A Retrospective Multi-Center Study

Purpose This study aimed to evaluate the utilization and outcomes of resuscitative endovascular balloon occlusion of the aorta (REBOA) in managing noncompressible torso hemorrhage (NCTH) among trauma patients in Korea. The evolution of REBOA and its impact on patient survival was investigated as well as predictors of mortality. Methods This retrospective study included 234 post-REBOA patients from 5 leading regional trauma centers across Korea between 2016 and 2021. Primary outcomes were in-hospital mortality, and secondary outcomes were various clinical parameters regarding REBOA, overall treatment flow, and complications. For comparative analyses, patients were dichotomized into in-hospital non-survivors or survivors. Then, generalized additive and linear regression models were used to evaluate the trend of in-hospital mortality. Results The overall in-hospital mortality was 65.4%. The survivors had a higher proportion of responders following REBOA (87.7% vs 62.7%, p < 0.001). Key variables influencing outcomes included total occlusion time, red blood cell transfusion volume within the first 24 hours, revised trauma score, and systolic blood pressure gap. These factors significantly correlated with mortality rates in multivariate logistic regression. Conclusion Over 6 years, survival rates for NCTH patients undergoing REBOA in Korea have shown improvement. Despite diverse REBOA protocols across institutions, the results underscore the need for continued research, standardized practices, and national quality control measures to further optimize patient outcome and establish more effective treatment protocols for NCTH

CD4+CD56+ Lineage Negative Hematopoietic Neoplasm : So Called Blastic NK Cell Lymphoma

Blastic natural killer (NK) cell lymphoma is a rare neoplasm characterized by blastoid tumor cells expressing CD4 and CD56, with predominant skin involvement. Although this tumor has been regarded as a neoplasm related to NK cell, recent studies suggested that it is derived from plasmacytoid dendritic cells, but not from NK cell. Herein we report 4 cases of CD4+CD56+ lineage marker- blastic NK cell lymphomas with a review of literatures. The patients were 3 men and one woman. Three of them were young (17, 18, and 22 yr old). Three patients had skin lesions, at initial presentation in two patients and during the course of disease in other patient. Histologically, tumors consisted of monotonous medium to large blastoid cells showing no necrosis, angiocentric growth or epidermotrophism. All four tumors were CD4+ and CD56+. Three expressed CD68 antigen. Lineage specific markers for B- and T cell were negative. All tumors did not express myeloperoxidase. T-cell receptor gene rearrangement, EBV, CD13 and CD33 were negative. In one patient, tumor cells arranged in Homer-Wright type pseudorosette and expressed terminal deoxynucleotidyl transferase (TdT). Despite the standard lymphoma chemotherapy, the tumors, except one lost during follow-up, progressed and relapsed. The patients died 8-60 months after diagnosis

Learning phonetically and phonologically natural classes through constraint indexation

Phonological processes tend to be defined over natural classes (Chomsky & Halle 1968), but there are some arbitrary and language-specific aspects to class behaviour (e.g., Mielke 2004). This paper shows that it is possible to implement a procedure of finding language specific natural classes using contrast detection (Dresher 2014, Sanstedt 2018), but in standard OT with domain-general methods. Three toy languages are constructed, based on those in Prickett & Jarosz (2021), in which /e/ raises to [i] in the presence of a high vowel and in which /s/ palatalizes to [ʃ] before [i]. In one language, raising feeds palatalization (transparent); in the second, raising counterfeeds palatalization (opaque); in the third, raising applies transparently, but only in certain morphemes (lexically specific). All three languages are learned with a version of Round’s (2017) learner that learns indexed constraints (Pater 2000) that are attached to specific segments in morphemes rather than entire morphemes (cf. Nazarov 2021). This learner is able to find appropriate natural classes for these data, both phonetic natural classes (=traditional natural classes) and what I call phonologically natural classes (classes defined by having certain phonetic properties and undergoing a range of phonological processes), showing the feasibility of this approach

A brief remark on the role of phonetics in phonology

It is generally agreed that classes of sounds that pattern together are typically definable in phonetic terms and common phonological processes often have a plausible phonetic origin. However, there is a great deal of disagreement in terms of the extent to which phonetics should be built into the phonological machinery or directly referenced by the phonological grammar. In this paper, I examine a few types of phenomena that bear on this issue and suggest how these cases could be handled by theories that adopt different views on the role of phonetics in phonology
