In the tradition of Interactional Linguistics, we show how speakers make use of Predicate Nominal Constructions (PNCs) in American English conversation. We first provide a grammatical profile of PNCs as a highly frequent type of low-transitive clause in actual everyday use. We then bring evidence to show that, functionally, speakers use PNCs specifically to do two types of more semantic work (to identify or categorize a referent) and two types of more interactional work (to inform about or assess a referent). Finally, we examine the role PNCs play in the social activity of building a characterization.

The so-called canonical clause, consisting of case-marked NPs and a final finite verb, has played a central role in discussions of Japanese for the past several decades. The current study explores the nature of such clauses in everyday Japanese conversation. Everyday conversation is considered the most fundamental form of language, and large-scale corpora of Japanese everyday conversation have only become available in recent years, enabling projects like ours. One key finding is that clauses ending with a finite verb are rare, challenging the centrality of the canonical clause in Japanese grammar. Instead, we observe that the verb is usually followed by additional elements that convey pragmatic information. This observation suggests that the canonical clause for Japanese speakers should also include these pragmatic elements. We have observed further that the relatively uncommon examples that do end with a finite verb often involve five frequent semantically light verbs. A preliminary study of one of these verbs, chigau ‘to differ’, reveals that, typically without overt NPs, it functions more like a particle than the verb of a clause. This further calls into question the idea that the canonical clause in Japanese ends with a finite verb.

We focus on (a) the indeterminacy of reference, i.e., noun phrases which are described as having a ‘given’, ‘old’ or ‘definite’ referent, where that referent is unspecified; (b) the ways in which speakers shift reference between categorial and specific designations. The data reveal that talk displaying indeterminate and shifting reference is consistently accepted without being challenged. These facts show that reference can only be understood by considering how speakers refer locally, in the unfolding of social action, and that referential common ground is generally established despite the referential indeterminacy and fluidity. We thus promote the view that reference is a deeply social phenomenon, an emergent set of practices that is used and negotiated by people in real time.

Background: Since gastric cancers (GCs) detected after Helicobacter pylori (HP) eradication present with different morphological characteristics from conventional HP-positive GCs, delayed detection of early-stage GCs may be observed. This study aimed to investigate the clinical impact of HP eradication on diagnosing GC during screening endoscopy. Methods: Eleven health checkup institutions in Japan participated in the present study. All GC cases newly diagnosed by screening endoscopy between January 2016 and December 2020 were included. After propensity score matching, multivariable regression analysis was performed to estimate the effect of HP eradication on deep tumor invasion among HP-eradicated and HP-positive GC cases. Results: A total of 231 patients with GCs (134 HP-eradicated and 97 HP-positive cases) were enrolled. After propensity score matching, there were 81 cases in each group. The distribution of the depth of tumor invasion (pT1a, pT1b1, pT1b2, and pT2) between the HP-eradicated group and HP-positive group was similar (p = 0.82). In the propensity analysis, with HP-positive as the reference value, HP eradication was not significantly associated with T1b–T4-GCs and T1b2–T4-GCs, with odds ratios (95% confidence intervals) of 1.16 (0.48–2.81) and 1.16 (0.42–3.19), respectively. Conclusions: HP eradication does not adversely affect the clinical course of GCs, supporting the recommendation of HP eradication in screening programs to reduce the total number of GC cases without delaying diagnosis.

Objective In the treatment of patients with schizophrenia, pro re nata (PRN) drugs are commonly prescribed for medical indications such as agitation, acute psychiatric symptoms, insomnia, and anxiety. However, high-quality evidence supporting the use of PRN medications is lacking, and these drugs are administered on the basis of clinical experience and habits. Therefore, the actual use of psychotropic PRN drugs and its influence on the patients’ outcomes need to be investigated. Methods This study included 205 patients who underwent inpatient treatment for schizophrenia. We investigated the prescription of psychotropic drugs before admission and at discharge, as well as the dosing frequency of PRN drugs during hospitalization. We also examined the influence of psychotropic PRN drug use on hospitalization days, antipsychotic polypharmacy, and readmission rates. Results Patients who used psychotropic PRN drugs during hospitalization had significantly longer hospitalization days (p = 7.5 × 10−4) and significantly higher rates of antipsychotic polypharmacy (p = 2.4 × 10−4) at discharge than those who did not use psychotropic PRN drugs. Moreover, a higher number of psychotropic PRN drugs used per day was associated with higher readmission rates within 3 months of discharge (p = 4.4 × 10−3). Conclusion Psychotropic PRN drug use is associated with prolonged hospitalization, antipsychotic polypharmacy, and increased readmission rates in inpatients with schizophrenia. Therefore, psychiatric symptoms should be stabilized with regularly prescribed medications without the extensive use of psychotropic PRN drugs. Moreover, a system for monitoring and reexamining PRN drug use needs to be established.

Voiceless nasal consonants are typologically rare in the world's languages. The present study investigates the acoustic realization of reported voiceless nasals in the Miyako Ryukyuan dialect Ikema. Voiceless nasals in Ikema occur word-initially and word-medially as part of a geminate or consonant cluster, and are phonemically distinct from modal voiced nasals. Initial observation of collected recordings revealed many instances of the voiceless phoneme with voicing throughout, leading to a re-evaluation of previous claims about its phonetic implementation. We hypothesized that word-medial and phrase-medial voiceless nasals surface as breathy voiced nasals. We analyzed the acoustic characteristics of nasal components of target words, focusing on duration, phonation state, and cepstral peak prominence (CPP), to determine whether reported voiceless nasal phonetic components with voicing are acoustically distinct from modal voiced nasal consonants. We find that voiceless nasals are produced with a voiceless component followed by a modal voiced component. Voiceless components and breathy components are found to be significantly shorter than modal components. We also find a significant difference between modal nasal, breathy nasal and voiceless nasal components' CPP values. The results confirm the observation that Ikema voiceless nasals are phonemically distinct from modal nasal consonants, and likely allophonically vary with breathy voiced nasals word-medially and phrase-medially. These findings align with the hypothesis that voiceless nasals require some voicing to be audible for perception, and are consistent with cross-linguistic findings, contributing to the typological understanding of the acoustics of voiceless nasals.

Elsinoë are plant pathogenic fungi that cause scabs, spotted anthracnose, and some morphological distortions on various plants, including woody plants, economically important crops, and ornamental plants. Taxonomical reexamination of Elsinoë species in Japan has not yet been conducted based on the modern species criteria. In this study, several Japanese isolates were reexamine based on the morphological and molecular-phylogenetic analysis of the internal transcribed spacer region (ITS), large subunit gene (LSU)m and protein-coding gene such as RNA polymerase II subunit (rpb2) and Translation elongation factor 1-alpha (tef). Japanese isolates were divided into four clades and three new species, Elsinoë hydrangeae, E. sumire, and E. tanashiensis were proposed. One species, Sphaceloma akebiae, was transferred to the genus Elsinoë.

AbstractA systematic investigation into the first large scale Japanese conversation corpus reveals that repeated verbs (RVs) occurring in the response position tend to involve frequently used verbs such asaru‘to exist’ andchigau‘to differ’ (e.g.,aru aru aru). Further, longer RVs, those involving more repetition, are even more likely to occur with frequent verbs. In RVs, we find the verb having lost some of its lexical meaning and phonological substance (e.g.,chigau>chiga). RVs in fact behave more like pragmatic particles functioning as reactive tokens, i.e., short responses interjected by non-main speakers. RVs as reactive tokens are most clearly observed when they are used together with standard reactive tokens such ashai hai hai hai‘yes, yes, yes, yes’,so(o) so(o) so(o)‘yes, yes, yes’, and(i)ya (i)ya (i)ya‘no, no, no’, which also exhibit repetition and phonological reduction. Verb repetition is thus better understood as a template to turn verbs into reactive tokens.

Introduction: Antipsychotics are still commonly prescribed to patients with dementia, despite the many issues that have been identified. This study aimed to quantify antipsychotic prescription in patients with dementia and the types of concomitant medications prescribed with antipsychotics. Methods: A total of 1,512 outpatients with dementia who visited our department between April 1, 2013 and March 31, 2021, were included in this study. Demographic data, dementia subtypes, and regular medication use at the time of the first outpatient visit were investigated. The association between antipsychotic prescriptions and referral sources, dementia subtypes, antidementia drug use, polypharmacy, and prescription of potentially inappropriate medications (PIMs) was evaluated. Results: The antipsychotic prescription rate for patients with dementia was 11.5%. In a comparison of dementia subtypes, the antipsychotic prescription rate was significantly higher for patients with dementia with Lewy bodies (DLB) than for those with all other dementia subtypes. In terms of concomitant medications, patients taking antidementia drugs, polypharmacy, and PIMs were more likely to receive antipsychotic prescriptions than those who were not taking these medications. Multivariate logistic regression analysis showed that referrals from psychiatric institutions, DLB, N-methyl-d-aspartate (NMDA) receptor antagonists, polypharmacy, and benzodiazepine were associated with antipsychotic prescriptions. Conclusions: Referrals from psychiatric institutions, DLB, NMDA receptor antagonist, polypharmacy, and benzodiazepine were associated with antipsychotic prescriptions for patients with dementia. To optimise prescription of antipsychotics, it is necessary to improve cooperation between local and specialised medical institutions for accurate diagnosis, evaluate the effects of concomitant medication administration, and solve the prescribing cascade.

It has been well established that Japanese has one type of cleft construction. This understanding was reached mostly through the examination of single Japanese sentences, constructed based on (pseudo-)cleft examples in English. We identify another type of cleft in Japanese based on the examination of everyday conversation data. This construction can be aptly considered a pseudo-cleft as it involves the interrogative pronoun nani 'what'. Both structurally and functionally, it behaves similarly to pseudo-clefts in several other languages and to the Japanese traditional cleft, as characterized in recent conversation-based studies.

A new area of research called Interactional Linguistics highlights linguistic structure in relation to naturally occurring interaction and is characterized by its cross-linguistic orientation. As a contribution to this new area of research, the present volume is a collection of papers with a cross-linguistic focus; they examine what is often called an ‘increment’, a grammatical extension of the already completed unit. In this paper, we briefly discuss frameworks and orientations adopted by these studies, as well as some overall themes and common issues.

This cross-linguistic study focuses on ways in which conversationalists speak beyond a point of possible turn completion in conversation, specifically on turn extensions which are grammatically dependent, backward-looking and extend the prior action. It argues that further distinctions can be made in terms of whether the extension is prosodically integrated with the prior unit, its host, (Non-add-on) or not, and in terms of whether it repairs some part of the host (Replacement) or not. Added-on, non-repairing extensions are further distinguished in terms of whether they are grammatically fitted to the end of the host (Glue-ons) or not (Insertables). A preliminary survey of TCU continuation in English, German and Japanese conversation reveals a number of significant differences with respect to frequency and range of extension type. English is at one extreme in preferring Glue-ons over Non-Add-ons and Insertables, whereas Japanese is at the other extreme in preferring Non-add-ons and Insertables over Glue-ons. German occupies an intermediary position but is on the whole more like Japanese. The preference for Glue-ons vs. Insertables appears to reflect a language’s tendency towards syntactic left- vs. right headedness. In conclusion the study argues for a classification of ‘increment’ types which goes beyond the English-based Glue-on, attributes a central role to prosodic delivery and adopts a usage-based understanding of word order.

Two potyviruses, uraria mosaic virus (UMV) and passiflora foetida virus Y (PfVY), have been detected in Japan for the first time, from newly bred passionfruit cultivars. Host range analyses and phylogenetic analyses based on full and partial polyprotein coding regions of UMV and PfVY, respectively, suggested they were distinct from viruses previously isolated from passionfruit. Both species belong to the BCMV subgroup within the genus Potyvirus , which contains other pathogenic passionfruit viruses.

In June 2017, deer-horn-like galls covered with a whitish, powdery fungal layer were found on the trunks of Cinnamomum pseudopedunculatum (Lauraceae) in Hahajima, Bonin Islands, Japan. The galls were similar to those of horn gall disease of Ci. tenuifolium caused by Laurobasidium hachijoense (Laurobasidiaceae, Exobasidiales) on Hachijo Island, approximately 700 km north of Hahajima. Based on morphological observation and molecular analyses of ITS and LSU regions, the fungus isolated from the surface of the galls was identified as L. hachijoense. This is the first report of the horn gall disease of Ci. pseudopedunculatum.

Abstract Our examination of Japanese everyday conversation reveals that a majority of candidate NPs cannot be established as NPs based on traditional criteria, i.e., marking by particles and modification, since they are generally unmarked and unmodified. We examine these cases to reveal the difficulty of determining what to consider an ‘NP’ when analyzing everyday interaction. Our findings question the assumption of NP as a universal category, and in particular cast doubt on the theoretical importance given to the category NP for Japanese in the literature. We recognize instead the quantitatively most frequent cases as the norm, with the minority, more ‘ornamented’, instances as requiring an account. Our study advocates routinely challenging assumed categories arising from our inherited written-language, English-dominated, imagined-data linguistic tradition, and instead shifting our descriptive and theoretical focus to understanding and accounting for the majority instances, in our case the role of unmarked nominals in a grammar of conversation.

In June 2015, a postharvest fruit rot of passion fruit (Passiflora edulis × P. edulis f. flavicarpa) was found in Hahajima, Bonin islands, Tokyo, Japan. A fungus with black pycnidia was often isolated from the rotted fruits. The fungus described recently as Diaporthe fructicola was demonstrated to reproduce natural symptoms. This fungus has pathogenicity to leaves and stems of passion fruit. It was also pathogenic to the fruits of lemon. We propose to call the new disease as Fruit Rot (migusare-byo in Japanese).

Abstract This chapter examines the phenomenon called ‘zero anaphora’ in Japanese where syntactic arguments, thought to be projected by the predicates, are assumed to be deleted yet their referents are still tracked. A close inspection of representative narrative and interactive segments reveals that everyday talk, the primordial form of language, is carried out largely through more or less fixed expressions which are better analyzed as not projecting syntactic arguments. This suggests that deletion of arguments and tracking of referents might not be relevant to the grammar of Japanese everyday talk. We demonstrate this by discussing several facts including: (1) inserting what might be thought of as ‘deleted’ arguments in relevant examples makes them consistently more marked, awkward, or even unacceptable and (2) ‘deleted’ arguments are often associated with multiple equally possible referents, or no referents. The predominance of fixed expressions in our data suggests that they constitute the basic type of language in Japanese everyday talk. It is hoped that the current study is a contribution to building a model of grammar which captures this very characteristic of everyday talk where (semi-) fixed structure continuously emerges.
