Clefts and anti-superiority in Moken

We describe an extraction asymmetry in Moken that presents apparent Anti-Superiority effects. We then show that this asymmetry is not rooted in Superiority at all. Evidence from island effects is used to demonstrate that the left-dislocation of wh-phrases is not the result of wh-movement as standardly conceived. Furthermore, the same Anti-Superiority effect obtains for non-wh-phrases and clefts. At the same time, standard Superiority effects in Moken do arise in certain environments. These observations lead to the conclusion that Anti-Superiority effects in Moken are not counterexamples to the universality of Superiority, but instead arise due to a constraint on crossed dependencies between arguments and non-argument positions

Two kinds of definites in numeral classifier languages

Numeral classifier languages distinguish definite noun phrases licensed by uniqueness from those licensed by familiarity. Unique definites are expressed by bare nouns or null pronouns, while familiar definites are expressed by indexicals such as demonstrative descriptions or overt pronouns. This generalization parallels the observation by Schwarz (2009) that German distinguishes unique versus familiar or anaphoric definiteness in its article system. The difference between the two kinds of definites can be reduced to the presence of a semantic index in the case of familiar definites. As familiar definites occur in most E-type contexts, including donkey anaphora, and uniqueness definites are not possible in these contexts, these facts provide support to dynamic analyses of E-type anaphora and pose problems for uniqueness-based approaches, such as the theory of Elbourne (2013)

Evidence for the Syntactic Diversity of Numeral Classifiers

I propose a syntactic typology of numeral classifier languages based on the observation that the order of nouns and numeral classifiers correlate with substantial differences in the syntactic uses of classifiers. In languages where classifiers precede nouns, they have an article-like use marking definiteness. We take this as evidence that classifiers are functional projections of the NP there, forming a constituent with that noun. In languages where classifiers follow nouns, they do not form a constituent with the head noun, explaining why these languages almost universally exhibit quantifier float of a quantifier+classifier constituent

Highlighting the Sustainability Implications of Urbanisation: A Comparative Analysis of Two Urban Areas in Ghana

Ghana is urbanising rapidly, and over half of the country’s population have lived in urban areas since 2010. Although research has proliferated to explore Ghana’s urbanisation, there is a dearth of research that holistically explores the wider sustainability implications of urbanisation, offers comparative perspectives in the context of large and smaller urban areas, and provides a perspective of local level urbanisation in the context of resource extraction (mining). This study comparatively assesses two urban areas in Ghana (Kumasi and Obuasi), by conducting a spatio-temporal analysis of land cover change through remote sensing and by analysing demographic change through a synthesis of published population data, in order to highlight the sustainability implications of urbanisation. The results show that urbanisation has been rapid, and has resulted in changes in land cover and demography in Kumasi and Obuasi. The sustainability implications of urbanisation are identified to include limited economic opportunities, socio-spatial segregation, and destruction of natural vegetation. The evidence in this study provides insights into urbanisation in Ghana, and suggests that the positive sustainability impacts of urbanisation may be eroded by how factors such as market forces and land tenure interact at the local level

Surveillance of infection associated with external ventricular drains: proposed methodology and results from a pilot study

Background The insertion of external ventricular drains (EVDs) is necessary in some neurosurgical patients, but increases the risk of meningitis/ventriculitis. While there are well-recognized risk factors, the proportion of patients who develop meningitis/ventriculitis varies partly due to differences in definitions. A multi-disciplinary working group was established to agree definitions for EVD-associated meningitis/ventriculitis, and a surveillance system was piloted in four centres in the UK and Ireland. Methods Definitions were agreed based on those published previously and on clinical and microbiological criteria. An agreed dataset was developed to monitor patients after the insertion of an EVD and until the EVD was removed and the microbial aetiology was recorded. Findings Four neurosurgical centres participated, with 61–564 patients surveyed in each unit. The vast majority of drains were cranial. Intracranial haemorrhage was the most common indication for the EVD insertion. Between 6% and 35% of EVDs were inserted by consultants rather than junior doctors. The proportion of patients who developed meningitis/ventriculitis varied from 3% to 18% and from 4.8 to 12.7/1000 EVD-days. Coagulase-negative staphylococci were the most common microbial causes. Conclusions Routine and ongoing monitoring of patients with an EVD in situ to detect meningitis/ventriculitis presents logistical difficulties, and few units do so. This pilot study suggests that a national system of surveillance with agreed definitions and a methodology to enable unit-to-unit comparisons of EVD meningitis/ventriculitis is both necessary and feasible. This will, in turn, inform quality improvement processes leading to the minimization of infection

Using Interleukin 6 and 8 in Blood and Bronchoalveolar Lavage Fluid to Predict Survival in Hematological Malignancy Patients With Suspected Pulmonary Mold Infection.

Background: Molds and other pathogens induce elevated levels of several cytokines, including interleukin (IL)-6 and IL-8. The objective of this study was to investigate the prognostic value of IL-6 and IL-8 as well as fungal biomarkers in blood and bronchoalveolar lavage fluid (BAL) for overall survival in patients with underlying hematological malignancies and suspected mold infection. Methods: This cohort study included 106 prospectively enrolled adult cases undergoing bronchoscopy. Blood samples were collected within 24 h of BAL sampling and, in a subset of 62 patients, serial blood samples were collected up until 4 days after bronchoscopy. IL-6, IL-8, and other cytokines as well as galactomannan (GM) and β-D-glucan (BDG) were assayed in blood and BAL fluid and associations with overall mortality were assessed at the end of the study using receiver operating characteristic (ROC) curve analysis. Results: Both blood IL-8 (AUC 0.731) and blood IL-6 (AUC 0.699) as well as BAL IL-6 (AUC 0.763) and BAL IL-8 (AUC 0.700) levels at the time of bronchoscopy were predictors of 30-day all-cause mortality. Increasing blood IL-6 levels between bronchoscopy and day four after bronchoscopy were significantly associated with higher 90-day mortality, with similar findings for increasing IL-8 levels. In ROC analysis the difference of blood IL-8 levels between 4 days after bronchoscopy and the day of bronchoscopy had an AUC of 0.829 (95%CI 0.71-0.95; p < 0.001) for predicting 90-day mortality. Conclusions: Elevated levels of IL-6 and IL-8 in blood or BAL fluid at the time of bronchoscopy, and rising levels in blood 4 days following bronchoscopy were predictive of mortality in these patients with underlying hematological malignancy who underwent bronchoscopy for suspected mold infection
