From Negation to Agreement: Revisiting the Problem of Sources for Socio-Historical Linguistics

In this article we review recent work on the history of French negation in relation to three key issues in socio-historical linguistics: identifying appropriate sources, interpreting scant or anomalous data, and interpreting generational differences in historical data. We then turn to a new case study, that of verbal agreement with la plupart, to see whether this can shed fresh light on these issues. We argue that organising data according to the author’s date of birth is methodologically sounder than according to date of publication. We explore the extent to which different genres and text types reflect changing patterns of usage and suggest that additional, different case-studies are required in order to make more secure generalisations about the reliability of different sources.

Diachronic Change in Verbal Agreement Patterns with Majorité

This article is concerned with the description of data relating to a case of morphosyntactic variation and change in French: verbal agreement patterns with the noun majorité (‘majority’). Quantitative analysis of apparent-time data from cloze (‘gap-fill’) tests suggests that plural agreement with this noun is increasing; data from a diachronic corpus study confirm that this is the case. A number of factors are found to constrain this variation and change, including most importantly the presence and number of a post-modifying noun phrase (e.g. la majorité des hommes). The implications of these findings for the definition of collective nouns in French are discussed.

Agreement between self-report and medical records on signs and symptoms of respiratory illness

Background: Information on patient symptoms can be obtained by patient self-report or medical records review. Both methods have limitations. Aims: To assess the agreement between self-report and documentation in the medical records of signs/symptoms of respiratory illness (fever, cough, runny nose, sore throat, headache, sinus problems, muscle aches, fatigue, earache, and chills). Methods: Respondents were 176 research participants in the Hutterite Influenza Prevention Study during the 2008-2009 influenza season with information about the presence or absence of signs/symptoms from both self-report and primary care medical records. Results: Compared with medical records, lower proportions of self-reported fever, sore throat, earache, cough, and sinus problems were found. Total agreements between self-report and medical report of symptoms ranged from 61% (for sore throat) to 88% (for muscle aches and earache), with kappa estimates varying from 0.05 (for chills) to 0.41 (for cough) and 0.51 (for earache). Negative agreement was considerably higher (from 68% for sore throat to 93% for muscle aches and earache) than positive agreement (from 13% for chills to 58% for earache) for each symptom except cough where positive agreement (77%) was higher than negative agreement (64%). Agreements varied by age group. We found better agreement for earache (kappa=0.62) and lower agreements for headache, sinus problems, muscle aches, fatigue, and chills in older children (aged =5 years) and adults. Conclusions: Agreements were variable depending on the specific symptom. Contrary to research in other patient populations which suggests that clinicians report fewer symptoms than patients, we found that the medical record captured more symptoms than selfreport. Symptom agreement and disagreement may be affected by the perspectives of the person experiencing them, the observer, the symptoms themselves, measurement error, the setting in which the symptoms were observed and recorded, and the broader community and cultural context of patients. © 2012 Primary Care Respiratory Society UK.

L'accord sujet-verbe en français contemporain: une étude de variation sociolinguistique

Cette communication a pour objectif de présenter et d’analyser les résultats d’une enquête portant sur l’accord sujet-verbe en français contemporain. Dans le domaine de l’accord sujet-verbe, bien que dans la plupart des cas le locuteur n’ait pas le choix de l’accord – c’est–à-dire qu’il n’y a qu’un accord possible – il existe néanmoins des contextes dans lesquels on peut trouver une variation entre l’accord singulier et le pluriel (cf. Corbett 2006 ; Grevisse 1993 ; Riegel et al 1994). Cette variation est souvent liée à une discordance entre le nombre syntaxique et le nombre sémantique. C’est le cas de certaines expressions de quantité, comme dans les exemples suivants : Singulier : « On a affaire à une minorité qui fait la loi à l’université » (Ouest France, 23-24 mai 2009, p.13) Pluriel : « Un petit millier de producteurs allemands, français et belges se sont déplacés, hier, à Bruxelles […] » (Ouest France, 26 mai 2009, p.3) Cette variation nous offre plusieurs pistes de recherche : dans une perspective linguistique, elle peut nous aider à mieux comprendre comment interagissent les différents facteurs linguistiques qui ont une influence sur l’accord, et dans une perspective sociolinguistique, elle représente un nouveau domaine à explorer pour l’étude sociolinguistique de la variation grammaticale en français, ce qui reste jusqu’à présent relativement peu étudiée. Nous traitons dans cette communication de la perspective sociolinguistique, c'est-à-dire les facteurs externes tels que l’âge, le sexe, et le niveau d’éducation du locuteur qui jouent un rôle dans l’accord sujet-verbe avec les expressions de quantité. Nous considérons en particulier la variation sexolectale : dans un premier temps, nous examinons les résultats de quelques études précédentes de la variation morphosyntaxique en français contemporain par rapport à l’influence du sexe du locuteur. Nous en concluons que les Principes élaborés par Labov (1990) pour décrire la variation sexolectale en anglais semblent être moins valables pour le cas du français de la France ; ou bien, qu’ils ne s’appliquent pas de façon simpliste. Dans un deuxième temps, nous présentons les résultats de nôtre étude, et nous voyons que pour nôtre projet aussi, les résultats pour la variation sexolectale ne s’expliquent pas facilement dans le cadre des Principes de Labov (1990).

Inter-observer agreement in evaluating the anterior chamber angle by ultrasound biomicroscopy

Purpose. To determine the agreement between observers in estimating the configuration of the human anterior chamber angle (ACA) using ultrasound biomicroscopy (UBM). Methods. Two masked clinicians used UBM images to estimate, in 41 eyes, the configuration of the ACA, especially (1) the position of contact between the peripheral iris and the inside of the eye wall, (2) the angularity of the approach to the ACA, and (3) the curvature of the peripheral iris. Agreement between observers was evaluated by the kappa statistic. Results. Inter-observer agreement in assessing the iris insertion (kappa = 0.79), angular width (Kappa = 0.95), and the peripheral iris curvature (kappa = 0.84) was high. Conclusions. The agreement between observers in evaluating the anterior chamber angle configuration by UBM was excellent.

Clinical agreement among glaucoma experts in the detection of glaucomatous changes of the optic disk using simultaneous stereoscopic photographs

PURPOSE: To evaluate the clinical agreement in the detection of optic disk changes in patients with glaucoma using simultaneous stereophotographs. DESIGN: Masked-observer variability study. METHODS: Ten glaucoma specialists examined pairs of simultaneous stereophotographs of glaucomatous and control optic disks to determine whether there were changes compatible with progression of glaucomatous damage. RESULTS: Intraobserver agreement had a kappa value ranging from 0.55 to 0.78. Interobserver agreement among the glaucoma specialists had a kappa value ranging from 0.34 to 0.68. CONCLUSION: Clinical examination of stereophotographs to detect optic disk changes in glaucoma patients has limitations associated with suboptimal reproducibility. © 2003 by Elsevier Inc.

Agreement between clinical and ultrasound biomicroscopy findings in different types of glaucoma

Purpose. To evaluate agreement between clinical examination (slit lamp examination and gonioscopy) and ultrasound biomicroscopy (UBM) in characterizing various features of the anterior chamber angle and adjacent structures. Methods. Twenty-eight patients (51 eyes) with open angle glaucoma (14), closed angle glaucoma (4), narrow angle and/or plateau iris (10), who had undergone UBM between March 94 and September 95 were studied. Evaluated parameters included angle width, iris configuration and presence of angle closure. The UBMs were reviewed in a masked fashion. Results. In 87.8% of cases there was agreement (within 10 degrees) between gonioscopic and UBM estimates of angle width. In all cases with greater than 10 degrees difference (12.2%) the angle size estimated by UBM was less than that estimated clinically. Iris configuration was graded identically in 51% of cases; the majority of disagreements (76.1%) occurred in cases graded as "regular" by gonioscopy and as "steep" by UBM. Angle closure was judged to be present more frequently by UBM. Conclusions. UBM and gonioscopy do not necessarily yield identical values for angle width, iris configuration, and presence of angle closure.

Systematic review of the agreement of tonometers with Goldmann applanation tonometry

OBJECTIVE: To assess the agreement of tonometers available for clinical practice with the Goldmann applanation tonometer (GAT), the most commonly accepted reference device.

DESIGN: A systematic review and meta-analysis of directly comparative studies assessing the agreement of 1 or more tonometers with the reference tonometer (GAT).

PARTICIPANTS: A total of 11 582 participants (15 525 eyes) were included.

METHODS: Summary 95% limits of agreement (LoA) were produced for each comparison.

MAIN OUTCOME MEASURES: Agreement, recordability, and reliability.

RESULTS: A total of 102 studies, including 130 paired comparisons, were included, representing 8 tonometers: dynamic contour tonometer, noncontact tonometer (NCT), ocular response analyzer, Ocuton S, handheld applanation tonometer (HAT), rebound tonometer, transpalpebral tonometer, and Tono-Pen. The agreement (95% limits) seemed to vary across tonometers: 0.2 mmHg (-3.8 to 4.3 mmHg) for the NCT to 2.7 mmHg (-4.1 to 9.6 mmHg) for the Ocuton S. The estimated proportion within 2 mmHg of the GAT ranged from 33% (Ocuton S) to 66% and 59% (NCT and HAT, respectively). Substantial inter- and intraobserver variability were observed for all tonometers.

CONCLUSIONS: The NCT and HAT seem to achieve a measurement closest to the GAT. However, there was substantial variability in measurements both within and between studies.
