Performativity, progressive avoidance and aspect

Unlike other reports of ongoing actions, English explicit performatives do not normally take progressive form. This suggests that “there is something over and above a mere concurrent report” in utterances like I bet you I’ll win the race that is absent in utterances like I’m betting you I’ll win the race (Levinson 1983: 259). For Krifka (2014), an explicit performative describes not the utterance act being produced, but the adoption of a new commitment, which has already happened at encoding time. If this is so, however, we might expect to find preterit- or present-perfect-form performative clauses and it appears that we do not. Using cross-linguistic data from genetically and geographically unrelated languages, we establish a strong typological tendency: explicit performative utterances use the same verbal construction that is used for reporting states holding at coding time. We attribute this tendency to an epistemic commonality between explicit performatives and state reports. In addition, we offer an explanation for exceptional uses of progressive aspect in apparently performative expressions, noted by, e.g., Searle (1989). Building on Dahl (1985), we have developed a questionnaire that allows us to identify the aspectual distinctions made in individual languages and which of these categories are employed in the various performative contexts (as classified by Searle 1976). Imperfective aspect is used to encode performatives and present-time states in, e.g., Arabic, Turkish and Bosnian/Croatian/Serbian. In Bantu languages like Lingala and Kirundi, performative predications receive perfective encoding, and this same form is used to report states holding at present. Japanese and the Austronesian language Kilivila feature unmarked verb forms in both present state reports and performative expressions. Progressive aspect is systematically excluded in the languages of our sample. Thus, in light of these typological observations, the use of the English simple present in performative contexts is not unexpected. The fact that present-time states and performative events receive the same aspectual construal across languages suggests a semantic commonality that cannot be conceived in terms of boundedness, one of the major parameters used to describe aspectual distinctions. We argue instead that aspectual categories encode epistemic distinctions, and that states and performative events are similar at this epistemic level: the situation type expressed by a performative or state predication is verifiable at the time of speaking. States have the subinterval property, according to which every segment of a state counts as an instance of that state, including that segment that overlaps the speech event. In the case of performatives, the reporting event and the performed event (promising, etc.) are one and the same; therefore, performative events are verifiable as such at speech time. The few scholars who touch on performativity and aspect in English appear to assume that in the rare attestations of progressive perfomatives, the predication does not perform a speech act (like promising) but rather reports on one’s own performance, as in I’m not just saying, I’m promising (Langacker 1987; Verschueren 1995; Krifka 2014). However, this characterization is not evidently applicable to examples like I’m warning you, Mrs. Hinkle: one more obscenity and I’ll charge you with contempt, which does count as a warning. Analysis of COCA data reveals that one type of performative clause, the exercitive type (Austin 1962), involving verbs such as warn and order, accounts for the majority of progressive performative tokens. Following McGowan (2004), we assume that exercitive acts change the boundaries of permissible or appropriate conduct. We postulate that progressive-form exercitive acts do not change these boundaries but rather describe an effort to do so. More generally, progressive performatives are action glosses like I’m trying to repair this; they explain the purpose of ongoing actions, both linguistic and nonlinguistic. This account naturally extends to non-exercitive progressive performatives like I’m withdrawing as a candidate

Characteristics associated with quality of life among people with drug-resistant epilepsy

Quality of Life (QoL) is the preferred outcome in non-pharmacological trials, but there is little UK population evidence of QoL in epilepsy. In advance of evaluating an epilepsy self-management course we aimed to describe, among UK participants, what clinical and psycho-social characteristics are associated with QoL. We recruited 404 adults attending specialist clinics, with at least two seizures in the prior year and measured their self-reported seizure frequency, co-morbidity, psychological distress, social characteristics, including self-mastery and stigma, and epilepsy-specific QoL (QOLIE-31-P). Mean age was 42 years, 54% were female, and 75% white. Median time since diagnosis was 18 years, and 69% experienced ≥10 seizures in the prior year. Nearly half (46%) reported additional medical or psychiatric conditions, 54% reported current anxiety and 28% reported current depression symptoms at borderline or case level, with 63% reporting felt stigma. While a maximum QOLIE-31-P score is 100, participants’ mean score was 66, with a wide range (25–99). In order of large to small magnitude: depression, low self-mastery, anxiety, felt stigma, a history of medical and psychiatric comorbidity, low self-reported medication adherence, and greater seizure frequency were associated with low QOLIE-31-P scores. Despite specialist care, UK people with epilepsy and persistent seizures experience low QoL. If QoL is the main outcome in epilepsy trials, developing and evaluating ways to reduce psychological and social disadvantage are likely to be of primary importance. Educational courses may not change QoL, but be one component supporting self-management for people with long-term conditions, like epilepsy

Psychological treatments for people with epilepsy.

BackgroundGiven the significant impact epilepsy may have on the health-related quality of life (HRQOL) of individuals with epilepsy and their families, there is increasing clinical interest in evidence-based psychological treatments, aimed at enhancing psychological and seizure-related outcomes for this group. This is an updated version of the original Cochrane Review published in Issue 10, 2017.ObjectivesTo assess the impact of psychological treatments for people with epilepsy on HRQOL outcomes.Search methodsFor this update, we searched the following databases on 12 August 2019, without language restrictions: Cochrane Register of Studies (CRS Web), which includes randomized or quasi-randomized controlled trials from the Specialized Registers of Cochrane Review Groups including Epilepsy, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (Ovid, 1946 to 09 August 2019), and PsycINFO (EBSCOhost, 1887 onwards), and from PubMed, Embase, ClinicalTrials.gov, and the World Health Organization International Clinical Trials Registry Platform (ICTRP). We screened the references from included studies and relevant reviews, and contacted researchers in the field for unpublished studies.Selection criteriaWe considered randomized controlled trials (RCTs) and quasi-RCTs for this review. HRQOL was the main outcome. For the operational definition of 'psychological treatments', we included a broad range of skills-based psychological treatments and education-only interventions designed to improve HRQOL, seizure frequency and severity, as well as psychiatric and behavioral health comorbidities for adults and children with epilepsy. These psychological treatments were compared to treatment as usual (TAU), an active control group (such as social support group), or antidepressant pharmacotherapy.Data collection and analysisWe used standard methodological procedures expected by Cochrane.Main resultsWe included 36 completed RCTs, with a total of 3526 participants. Of these studies, 27 investigated skills-based psychological interventions. The remaining nine studies were education-only interventions. Six studies investigated interventions for children and adolescents, three studies investigated interventions for adolescents and adults, and the remaining studies investigated interventions for adults. Based on satisfactory clinical and methodological homogeneity, we pooled data from 11 studies (643 participants) that used the Quality of Life in Epilepsy-31 (QOLIE-31) or other QOLIE inventories (such as QOLIE-89 or QOLIE-31-P) convertible to QOLIE-31. We found significant mean changes for the QOLIE-31 total score and six subscales (emotional well-being, energy and fatigue, overall QoL, seizure worry, medication effects, and cognitive functioning). The mean changes in the QOLIE-31 total score (mean improvement of 5.23 points, 95% CI 3.02 to 7.44; P Authors' conclusionsImplications for practice: Skills-based psychological interventions improve HRQOL in adults and adolescents with epilepsy. Adjunctive use of skills-based psychological treatments for adults and adolescents with epilepsy may provide additional benefits in HRQOL when these are incorporated into patient-centered management. We judge the evidence to be of moderate certainty.Implications for researchInvestigators should strictly adhere to the CONSORT guidelines to improve the quality of reporting on their interventions. A thorough description of intervention protocols is necessary to ensure reproducibility. When examining the effectiveness of psychological treatments for people with epilepsy, the use of standardized HRQOL inventories, such as the Quality of Life in Epilepsy Inventories (QOLIE-31, QOLIE-31-P, and QOLIE-89) would increase comparability. Unfortunately, there is a critical gap in pediatric RCTs and RCTs including people with epilepsy and intellectual disabilities. Finally, in order to increase the overall quality of RCT study designs, adequate randomization with allocation concealment and blinded outcome assessment should be pursued. As attrition is often high in research that requires active participation, an intention-to-treat analysis should be carried out. Treatment fidelity and treatment competence should also be assessed. These important dimensions, which are related to 'Risk of bias' assessment, should always be reported

Transplant Physicians’ Attitudes on Candidacy for Allogeneic Hematopoietic Cell Transplantation (HCT) in Older Patients: The Need for a Standardized Geriatric Assessment (GA) Tool

Background Despite improvements in conditioning regimens and supportive care having expanded the curative potential of HCT, underutilization of HCT in older adults persists (Bhatt VR et al, BMT 2017). Therefore, we conducted a survey of transplant physicians (TP) to determine their perceptions of the impact of older age (≥60 years) on HCT candidacy and utilization of tools to gauge candidacy. Methods We conducted a 23-item, online cross-sectional survey of adult physicians recruited from the Center for International Blood and Marrow Transplant Research between May and July 2019. Results 175/770 (22.7%) TP completed the survey; majority of respondents were 41-60 years old, male, and practicing in a teaching hospital. Over 75% were at centers performing ≥50 HCT per year. When considering regimen intensity, most (96%, n=168) had an upper age limit (UAL) for using a myeloablative regimen (MAC), with only 29 physicians (17%) stating they would consider MAC for patients ≥70 years. In contrast, when considering a reduced intensity/non-myeloablative conditioning (RIC/NMA), 8%, (n=13), 54% (n=93), and 20% (n=35) stated that age 70, 75, and 80 years respectively would be the UAL to use this approach, with 18% (n=31) reporting no UAL. TP agreed that Karnofsky Performance Score (KPS) could exclude older pts for HCT, with 39.1% (n=66), 42.6% (n=72), and 11.4% (n=20) requiring KPS of ≥70, 80, and 90, respectively. The majority (n=92, 52.5%) indicated an HCT-comorbidity index threshold for exclusion, mostly ranging from ≥3 to ≥ 5. Almost all (89.7%) endorsed the need for a better health assessment of pre-HCT vulnerabilities to guide candidacy for pts ≥60 with varied assessments being utilized beyond KPS (Figure 1). However, the majority of centers rarely (33.1%) or never (45.7%) utilize a dedicated geriatrician/geriatric-oncologist to assess alloHCT candidates ≥60 yrs. The largest barriers to performing GA included uncertainty about which tools to use, lack of knowledge and training, and lack of appropriate clinical support staff (Figure 2). Approximately half (n=78, 45%) endorsed GA now routinely influences candidacy. Conclusions The vast majority of TP will consider RIC/NMA alloHCT for patients ≥70 years. However, there is heterogeneity in assessing candidacy. Incorporation of GA into a standardized and easily applied health assessment tool for risk stratification is an unmet need. The recently opened BMT CTN 1704 may aid in addressing this gap

Large expert-curated database for benchmarking document similarity detection in biomedical literature search

Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations. More importantly, annotations of the same document pairs contributed by different scientists were highly concordant. We further show that the three representative baseline methods used to generate recommended articles for evaluation (Okapi Best Matching 25, Term Frequency-Inverse Document Frequency and PubMed Related Articles) had similar overall performances. Additionally, we found that these methods each tend to produce distinct collections of recommended articles, suggesting that a hybrid method may be required to completely capture all relevant articles. The established database server located at https://relishdb.ict.griffith.edu.au is freely available for the downloading of annotation data and the blind testing of new methods. We expect that this benchmark will be useful for stimulating the development of new powerful techniques for title and title/abstract-based search engines for relevant articles in biomedical research.Peer reviewe

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

Diagnosis and management of Cornelia de Lange syndrome:first international consensus statement

Cornelia de Lange syndrome (CdLS) is an archetypical genetic syndrome that is characterized by intellectual disability, well-defined facial features, upper limb anomalies and atypical growth, among numerous other signs and symptoms. It is caused by variants in any one of seven genes, all of which have a structural or regulatory function in the cohesin complex. Although recent advances in next-generation sequencing have improved molecular diagnostics, marked heterogeneity exists in clinical and molecular diagnostic approaches and care practices worldwide. Here, we outline a series of recommendations that document the consensus of a group of international experts on clinical diagnostic criteria, both for classic CdLS and non-classic CdLS phenotypes, molecular investigations, long-term management and care planning
