The clause in English : in honour of Rodney Huddleston
The focus in this volume is on grammatical aspects of the clause in English, presenting a fine balance between theoretically- and descriptively-oriented approaches. Some authors investigate the status and properties of 'minor' or 'fringe' constructions, including 'deictic-presentationals'; non-restrictive relative clauses with that; 'isolated if-clauses', and 'exceptional clauses'. In some articles the validity of conventional accounts and approaches is questioned: such as traditional constituency trees and labelled bracketings as a means of representing relationships between parenthetical elements and their 'hosts'; or traditional morphophonemic analyses as explanations for Ross's 'doubl-ing' constraint. While some authors question commonly made assumptions (for example those concerning the relationships of clauses to sentences and propositions; or those concerning the status of post-head dependents in the NP), others appeal to new frameworks (for instance 'emergence theory' is used as a source of inspiration in dealing with 'intransitive prepositions'). This collection also includes articles that adopt a solidly corpus-based approach.The Clause in English has been prepared by colleagues past and present, friends and admirers of Rodney Huddleston, in order to honour his consistently outstanding contribution to grammatical theory and description.
Comparative studies in Australian and New Zealand English : grammar and beyond
In this chapter, we provide an account of antipodean swearing patterns, drawing on examples from existing written and spoken data banks. As part of this investigation, we consider general questions to do with swearing: what it is, why speakers do it and how swearing patterns have changed over the years. We identify four overlapping functions of swearing: the expletive, abusive, social and stylistic functions. We also consider the shift in social attitudes toward swearing and the repercussions of this for the law. Swearing has always been characterized as an earmark of Australian and New Zealand English. We conclude that it remains an important feature of these varieties, but question just how uniquely antipodean it is.
Grammatical Change in English World-Wide
This chapter examines the use of the progressive aspect in Black South African English (BSAfE) since the late 19th century in corpora of fiction and newspapers. Previous research points to on-going change in native varieties and the extension to stative contexts in non-native varieties of English. The findings are: There has been a consistent increase in the frequency of the construction. Stative and achievement verbs are used in the progressive aspect proportionally more often in BSAfE than in native varieties. The progressive with stative verbs encodes states of longer duration alongside the meaning of temporary duration which is conventional in native varieties. The functional differences are not a recent or gradual innovation, but are present from the earliest available BSAfE data. Keywords: Black South African English; progressive aspect; stative verbs; duration.
Modals and quasi-modals in English
Modals and Quasi-modals in English reports the findings of a corpus-based study of the modals and a set of semantically-related 'quasi-modals' in English. The study is the largest and most comprehensive to date in this area, and is informed by recent developments in the study of modality, including grammaticalization and recent diachronic change. The selection of the parallel corpora used, representing British, American and Australian English, was designed to facilitate the exploration of both regional and stylistic variation.
English in Australia
This unique collection fills a ten-year gap in studies on the nature of Australian English, and it is the first to deal exclusively with varieties of English on the Australian continent. The book contains chapters on the phonology, morphology, syntax and the lexicon of the dialect, and chapters on variation within the dialect that include Aboriginal and ethnic varieties as well as regional and generational differences with a focus on questions of Australian identity and intercultural relations. With selected contributions by Australia's leading linguists this volume records the most recent developments in the study of English within Australia.
Ancient proteins from ceramic vessels at Çatalhöyük West reveal the hidden cuisine of early farmers
The analysis of lipids (fats, oils and waxes) absorbed within archaeological pottery has revolutionized the study of past diets and culinary practices. However, this technique can lack taxonomic and tissue specificity and is often unable to disentangle signatures resulting from the mixing of different food products. Here, we extract ancient proteins from ceramic vessels from the West Mound of the key early farming site of Çatalhöyük in Anatolia, revealing that this community processed mixes of cereals, pulses, dairy and meat products, and that particular vessels may have been reserved for specialized foods (e.g., cow milk and milk whey). Moreover, we demonstrate that dietary proteins can persist on archaeological artefacts for at least 8000 years, and that this approach can reveal past culinary practices with more taxonomic and tissue-specific clarity than has been possible with previous biomolecular techniques. Ancient diets have been reconstructed from archaeological pottery based on lipid remains, but these can lack specificity. Here, Hendy and colleagues analyze ancient proteins from ceramic vessels up to 8000 years old to produce a more nuanced understanding of ancient food processing and diet.
Mega-disturbances cause rapid decline of mature conifer forest habitat in California
Mature forests provide important wildlife habitat and support critical ecosystem functions globally. Within the dry conifer forests of the western United States, past management and fire exclusion have contributed to forest conditions that are susceptible to increasingly severe wildfire and drought. We evaluated declines in conifer forest cover in the southern Sierra Nevada of California during a decade of record disturbance by using spatially comprehensive forest structure estimates, wildfire perimeter data, and the eDaRT forest disturbance tracking algorithm. Primarily due to the combination of wildfires, drought, and drought-associated beetle epidemics, 30% of the region’s conifer forest extent transitioned to nonforest vegetation during 2011–2020. In total, 50% of mature forest habitat and 85% of high density mature forests either transitioned to lower density forest or nonforest vegetation types. California spotted owl protected activity centers (PAC) experienced greater canopy cover decline (49% of 2011 cover) than non-PAC areas (42% decline). Areas with high initial canopy cover and without tall trees were most vulnerable to canopy cover declines, likely explaining the disproportionate declines of mature forest habitat and within PACs. Drought and beetle attack caused greater cumulative declines than areas where drought and wildfire mortality overlapped, and both types of natural disturbance far outpaced declines attributable to mechanical activities. Drought mortality that disproportionately affects large conifers is particularly problematic to mature forest specialist species reliant on large trees. However, patches of degraded forests within wildfire perimeters were larger with greater core area than those outside burned areas, and remnant forest habitats were more fragmented within burned perimeters than those affected by drought and beetle mortality alone. The percentage of mature forest that survived and potentially benefited from lower severity wildfire increased over time as the total extent of mature forest declined. These areas provide some opportunity for improved resilience to future disturbances, but strategic management interventions are likely also necessary to mitigate worsening mega-disturbances. Remaining dry mature forest habitat in California may be susceptible to complete loss in the coming decades without a rapid transition from a conservation paradigm that attempts to maintain static conditions to one that manages for sustainable disturbance dynamics.
Nutritional Support in Malnourished Outpatients with Chronic Obstructive Pulmonary Disease (COPD): A Randomized Controlled Pilot Study
(1) Background: The evidence for nutritional support in COPD is almost entirely based on ready-to-drink oral nutritional supplements (ONSs). This study aimed to explore the effectiveness of powdered ONSs alongside individualized dietary counseling in the management of malnutrition. (2) Methods: Malnourished outpatients with COPD were randomized to receive either routine care (Group A: counseling + recommended to purchase powdered ONSs) or an enhanced intervention (Group B: counseling + provision of powdered ONSs at no cost to the patient) for 12 weeks. Outcomes of interest were nutritional intake, weight status, and quality of life. (3) Results: A total of 33 outpatients were included, categorized as follows: Group A (n = 21); Group B (n = 12); severely malnourished (n = 9), moderately malnourished (n = 24), mean BMI 18.0 SD 2.5 kg/m2. No differences were observed between groups at baseline or at week 12; however, analysis of the whole cohort (Group A + B) revealed nutrition intervention resulted in significant improvements in protein intake (+25.4 SD 53.4 g/d; p = 0.040), weight (+1.1 SD 2.6 kg; p = 0.032) and quality of life (−4.4 SD 10.0; p = 0.040). Only 41.2% of Group A and 58.3% of Group B reported consuming ONSs at week 12. Adherence to ONSs was associated with weight gain (+1.9 SD 2.5 kg vs. +0.4 SD 2.5 kg; p = 0.098). (4) Conclusions: Nutritional support results in significant improvements in nutrition status and quality of life in malnourished outpatients with COPD. However, improvements are associated with adherence to ONSs, suggesting the type of ONSs and how they are provided are important considerations in clinical practice and future studies.
Determinants of medication adherence in patients with acute coronary syndrome: a secondary analysis of a randomised clinical trial
BackgroundCoronary heart disease (CHD) remains a leading cause of mortality and disability worldwide. Approximately half of the patients who have had a prior hospital admission for CHD will have a recurrent coronary event, with the majority of these occurring within 12 months. Despite well-established evidence-based therapies, medication non-adherence is highly prevalent and reasons for medication non-adherence are poorly understood. This study evaluates factors influencing adherence to secondary prevention medications in people with acute coronary syndrome (ACS).MethodsWe performed a secondary analysis of TEXT messages to improve MEDication adherence and Secondary prevention after ACS (TEXTMEDS), a single-blind randomised clinical trial of 1424 patients with ACS from 18 hospitals across Australia. The primary outcome was self-reported medication adherence to each of up to five classes of guideline-recommended cardioprotective medications indicated for secondary prevention after ACS. Patients were followed up at 6-month and 12-month time points and were defined as adherent if at both time points, the proportion of indicated medications taken was >80% (>24/30 days in the preceding 1 month) for all five classes if not otherwise contraindicated. Logistic regression analysis and the Least Absolute Shrinkage and Selection Operator regularisation technique were used to assess the effect of sociodemographic and clinical factors on medication adherence.ResultsThe analyses included 1379 participants with complete adherence data (mean age 58.5±10.7 years; 1095 (79.4%) men). The following variables were associated with adherence to cardiovascular medications at both 6 and 12 months: greater number of total medications taken (OR: 1.33; 95% CI: 1.25 to 1.42) and attending a cardiac rehabilitation programme (1.47; 95% CI: 1.17 to 1.86). In contrast, female sex (0.67; 95% CI: 0.50 to 0.90) and physical disability (0.43; 95% CI: 0.23 to 0.77) were associated with lower likelihood of medication adherence.ConclusionsSociodemographic and clinical factors may influence medication adherence. Greater awareness, discussion and monitoring of these factors during patient follow-up may help improve medication adherence.Trial registration numberAustralian New Zealand Clinical Trials Registry; URL: https://www.anzctr.org.au/Trial/Registration/TrialReview.aspx?id=364448; registration number: ACTRN12613000793718.
From land use to land cover: restoring the afforestation signal in a coupled integrated assessment–earth system model and the implications for CMIP5 RCP simulations
Climate projections depend on scenarios of fossil fuel emissions and land use change, and the Intergovernmental Panel on Climate Change (IPCC) AR5 parallel process assumes consistent climate scenarios across integrated assessment and earth system models (IAMs and ESMs). The CMIP5 (Coupled Model Intercomparison Project Phase 5) project used a novel \"land use harmonization\" based on the Global Land use Model (GLM) to provide ESMs with consistent 1500–2100 land use trajectories generated by historical data and four IAMs. A direct coupling of the Global Change Assessment Model (GCAM), GLM, and the Community ESM (CESM) has allowed us to characterize and partially address a major gap in the CMIP5 land coupling design: the lack of a corresponding land cover harmonization. For RCP4.5, CESM global afforestation is only 22% of GCAM's 2005 to 2100 afforestation. Likewise, only 17% of GCAM's 2040 afforestation, and zero pasture loss, were transmitted to CESM within the directly coupled model. This is a problem because GCAM relied on afforestation to achieve RCP4.5 climate stabilization. GLM modifications and sharing forest area between GCAM and GLM within the directly coupled model did not increase CESM afforestation. Modifying the land use translator in addition to GLM, however, enabled CESM to include 66% of GCAM's afforestation in 2040, and 94% of GCAM's pasture loss as grassland and shrubland losses. This additional afforestation increases CESM vegetation carbon gain by 19 PgC and decreases atmospheric CO2 gain by 8 ppmv from 2005 to 2040, which demonstrates that CESM without additional afforestation simulates a different RCP4.5 scenario than prescribed by GCAM. Similar land cover inconsistencies exist in other CMIP5 model results, primarily because land cover information is not shared between models. Further work to harmonize land cover among models will be required to increase fidelity between IAM scenarios and ESM simulations and realize the full potential of scenario-based earth system simulations.
