Comparative alternation in y-adjectives
There are two main ways of expressing the comparative in English adjectives. One is to precede the adjectival base with more and the other is to suffix -er to the base. For the group of adjectives ending in an orthographic -y and an /i/ sound, which I call the y-adjectives, the alternation between more and -er cannot be neatly explained by structural accounts, whether predominantly synchronic or diachronic. The idea of understanding this alternation with respect to a paradigm of comparative constructions is introduced in this thesis. This paradigm comprises a multitude of more and -er constructions (including those of y-adjectives) that share the grammatical function of the comparative. The goal of this thesis is to examine to what extent the comparatives of y-adjectives can be accounted for by the comparative constructions of other members in this paradigm, in addition to a set of syntactic, morphological and phonological considerations. Two empirical studies are reported: a study of the comparative constructions in seven corpora of British comedies spanning the 17th to the 20th centuries; and an experimental study where reading times in the context of comparative y-adjective constructions were observed in a series of self-paced reading tasks. In the corpus study, the morphology of y-adjective bases is found to be a significant predictor of their comparatives. Additionally, significant correlations are found between:
• the comparatives of y-adjectives and those of the disyllabic adjectives that are not y-adjectives (to which I have given the cover term of HANDSOME adjectives);
• the comparatives of y-adjectives and those of the monosyllabic adjectives; and
• the comparatives of y-adjectives and those of adverbs that share some formal features with y-adjectives.
The experimental study furthers an investigation of comparative alternation in y-adjectives in terms of the comparatives of HANDSOME adjectives and the morphological structure of y-adjective bases. In this study, pre-to-post treatment reading is found to be facilitated in y-adjective more comparatives by an exposure to multiple instances of more constructions from the HANDSOME adjectives. The more constructions from HANDSOME adjectives are also found to reduce facilitation in reading in morphologically simple y-adjectives paired with -er. On the other hand, the -er constructions from HANDSOME adjectives are found to reduce facilitation in reading in morphologically complex y-adjectives paired with more. The studies undertaken in this work indicate two important predictors of the comparatives of y-adjectives: the comparatives of HANDSOME adjectives; and the morphological structure of y-adjective bases. The involvement of the comparatives of HANDSOME adjectives as a predictor points to the importance of a paradigm of comparatives for an understanding of the comparatives of y-adjectives. The influence of this paradigm, combined with the influence of morphology, is argued to shed light on a question motivated by the diachronic literature on what could be suppressing the susceptibility of y-adjectives to the structural motivators for particular comparatives. Additionally, the potential for interpreting some unanticipated findings in terms of theories from psychological views on language, and in ways that remain coherent with paradigmatic and morphological viewpoints, is discussed
Introduction: Turbulent Circulation: Building a Critical Engagement with Logistics
Since the mid-20th century, logistics has evolved into a wide-ranging science of circulation involved in planning and managing flows of innumerable kinds. In this introductory essay, we take stock of the ascendancy and proliferation of logistics, proposing a critical engagement with the field. We argue that logistics is not limited to the management of supply chains, military or corporate. Rather, it is better understood as a calculative logic and spatial practice of circulation that is at the fore of the reorganization of capitalism and war. Viewed from this perspective, the rise of logistics has transformed not only the physical movement of materials but also the very rationality by which space is organized. It has remade economic and military space according to a universalizing logic of abstract flow, exacerbating existing patterns of uneven geographical development. Drawing on the articles that make up this themed issue, we propose that a critical approach to logistics is characterized by three core commitments: (1) a rejection of the field’s self-depiction as an apolitical science of management, along with a commitment to highlighting the relations of power and acts of violence that underpin it; (2) an interest in exposing the flaws, irrationalities, and vulnerabilities of logistical regimes; and (3) an orientation toward contestation and struggle within logistical networks
Influence of ethnicity on aesthetic preferences for lip characteristics in Caucasian male and female faces
Background: In an era where globalization and social media significantly reshape beauty standards, it is imperative to delve into the subjectivity of beauty and attractiveness. The lips, a key element in facial aesthetics, contribute significantly to the perception of attractiveness, and also have a profound impact on an individual's self-esteem. Objective: To analyze the influence of ethnicity on the aesthetic preferences for lip characteristics, among male and female faces. Materials and methods: This study encompassed a sample of 231 study participants (153 women and 78 men) with an average age of 23.2 ± 2.8 years, representing ethnicities such as African, Caucasian, Middle Eastern, and South Asian. Participants were asked to rate a series of images showcasing various lip variants, providing insights into their aesthetic preferences. Results: Demographic analysis revealed gender and ethnic variations in aesthetic preferences for all the investigated lip parameters. Women were 2.42 times more likely than men to prefer no Cupid's indentation on a female model (p = 0.0019). Conclusions: The study underscores the importance of understanding cultural influences on beauty standards and challenges the notion of a universal beauty ideal. The evolving role of social media trends, such as Cupid's bow indentation elimination, raises questions about the dynamic nature of aesthetic preferences among different ethnicities.</p

Percutaneous Computed Tomography-Guided Oxygen-Ozone (O<sub>2</sub>O<sub>3</sub>) Injection Therapy in Patients with Lower Back Pain—An Interventional Two-Year Follow-Up Study of 321 Patients
Objectives: To assess the effect of oxygen-ozone therapy guided by percutaneous Computed Tomography (CT) compared to corticosteroids in individuals experiencing lower back pain (LBP) not attributed to underlying bone-related issues. Methods: A total of 321 patients (192 males and 129 females, mean age: 51.5 ± 15.1 years) with LBP were assigned to three treatment groups: group A) oxygen-ozone only, group B) corticosteroids only, group C) oxygen-ozone and corticosteroids. Treatment was administered via CT-guided injections to the intervertebral disc (i.e., intradiscal location). Clinical improvement of pain and functionality was assessed via self-reported pain scales and magnetic resonance (MR) and CT imaging. Results: At all follow-up times, the mean score of the numeric rating scale and the total global pain scale (GPS) of study groups receiving oxygen-ozone (groups A and C) were statistically significantly lower than the study group receiving corticosteroids only (group B), with p < 0.001. There was a statistically significant difference between groups A and C at 30 days for the numeric rating scale. Conclusions: The percutaneous application of oxygen-ozone in patients with LBP due to degeneration of the lumbosacral spine showed long-lasting significant pain reduction of up to two years post-treatment when compared to corticosteroids alone. Combination therapy of oxygen-ozone and corticosteroids can be useful as corticosteroids showed statistically significant improvement in LBP earlier than the oxygen-ozone-only treatment.</p
Genome Sequence Conservation of Hendra Virus Isolates during Spillover to Horses, Australia
Bat-to-horse transmission of Hendra virus has occurred at least 14 times. Although clinical signs in horses have differed, genome sequencing has demonstrated little variation among the isolates. Our sequencing of 5 isolates from recent Hendra virus outbreaks in horses found no correlation between sequences and time or geographic location of outbreaks
Human mucosal associated invariant T cells detect bacterially infected cells
Control of infection with Mycobacterium tuberculosis (Mtb) requires Th1-type immunity, of which CD8+ T cells play a unique role. High frequency Mtb-reactive CD8+ T cells are present in both Mtb-infected and uninfected humans. We show by limiting dilution analysis that nonclassically restricted CD8+ T cells are universally present, but predominate in Mtbuninfected individuals. Interestingly, these Mtb-reactive cells expressed the Va7.2 T-cell receptor (TCR), were restricted by the nonclassical MHC (HLA-Ib) molecule MR1, and were activated in a transporter associated with antigen processing and presentation (TAP) independent manner. These properties are all characteristics of mucosal associated invariant T cells (MAIT), an "innate" T-cell population of previously unknown function. These MAIT cells also detect cells infected with other bacteria. Direct ex vivo analysis demonstrates that Mtb-reactive MAIT cells are decreased in peripheral blood mononuclear cells (PBMCs) from individuals with active tuberculosis, are enriched in human lung, and respond to Mtb-infected MR1-expressing lung epithelial cells. Overall, these findings suggest a generalized role for MAIT cells in the detection of bacterially infected cells, and potentially in the control of bacterial infection. © 2010 Gold et al
The N3RO trial: a randomised controlled trial of docosahexaenoic acid to reduce bronchopulmonary dysplasia in preterm infants < 29 weeks’ gestation
Background: Bronchopulmonary dysplasia (BPD) is a major cause of mortality and long-term respiratory and neurological morbidity in very preterm infants. While survival rates of very preterm infants have increased over the past two decades there has been no decrease in the rate of BPD in surviving infants. Evidence from animal and human studies has suggested potential benefits of docosahexaenoic acid (DHA), an n-3 long chain polyunsaturated fatty acid, in the prevention of chronic lung disease. This randomised controlled trial aims to determine the effectiveness of supplementary DHA in reducing the rate of BPD in infants less than 29 weeks’ gestation.
Methods/design: This is a multicentre, parallel group, randomised, blinded and controlled trial. Infants born less than 29 weeks’ gestation, within 3 days of first enteral feed and with parent informed consent are eligible to participate. Infants will be randomised to receive an enteral emulsion containing DHA or a control emulsion without DHA. The DHA emulsion will provide 60 mg/kg/day of DHA. The study emulsions will continue to 36 weeks’ postmenstrual age (PMA). The primary outcome is BPD as assessed by the requirement for supplemental oxygen and/or assisted ventilation at 36 weeks’ PMA. Secondary outcomes include the composite of death or BPD; duration of respiratory support and hospitalisation, major neonatal morbidities. The target sample size is 1244 infants (622 per group), which will provide 90 % power to detect a clinically meaningful absolute reduction of 10 % in the incidence of BPD between the DHA and control emulsion (two tailed α =0.05).
Discussion: DHA supplementation has the potential to reduce respiratory morbidity in very preterm infants. This multicentre trial will provide evidence on whether an enteral DHA supplement reduces BPD in very preterm infants
Henipavirus Mediated Membrane Fusion, Virus Entry and Targeted Therapeutics
The Paramyxoviridae genus Henipavirus is presently represented by the type species Hendra and Nipah viruses which are both recently emerged zoonotic viral pathogens responsible for repeated outbreaks associated with high morbidity and mortality in Australia, Southeast Asia, India and Bangladesh. These enveloped viruses bind and enter host target cells through the coordinated activities of their attachment (G) and class I fusion (F) envelope glycoproteins. The henipavirus G glycoprotein interacts with host cellular B class ephrins, triggering conformational alterations in G that lead to the activation of the F glycoprotein, which facilitates the membrane fusion process. Using the recently published structures of HeV-G and NiV-G and other paramyxovirus glycoproteins, we review the features of the henipavirus envelope glycoproteins that appear essential for mediating the viral fusion process, including receptor binding, G-F interaction, F activation, with an emphasis on G and the mutations that disrupt viral infectivity. Finally, recent candidate therapeutics for henipavirus-mediated disease are summarized in light of their ability to inhibit HeV and NiV entry by targeting their G and F glycoproteins
Clinical and molecular epidemiology of methicillin-resistant Staphylococcus aureus in New Zealand: rapid emergence of sequence type 5 (ST5)-SCCmec-IV as the dominant community-associated MRSA clone.
The predominant community-associated MRSA strains vary between geographic settings, with ST8-IV USA300 being the commonest clone in North America, and the ST30-IV Southwest Pacific clone established as the dominant clone in New Zealand for the past two decades. Moreover, distinct epidemiological risk factors have been described for colonisation and/or infection with CA-MRSA strains, although these associations have not previously been characterized in New Zealand. Based on data from the annual New Zealand MRSA survey, we sought to describe the clinical and molecular epidemiology of MRSA in New Zealand. All non-duplicate clinical MRSA isolates from New Zealand diagnostic laboratories collected as part of the annual MRSA survey were included. Demographic data was collected for all patients, including age, gender, ethnicity, social deprivation index and hospitalization history. MRSA was isolated from clinical specimens from 3,323 patients during the 2005 to 2011 annual surveys. There were marked ethnic differences, with MRSA isolation rates significantly higher in Māori and Pacific Peoples. Over the study period, there was a significant increase in CA-MRSA, and a previously unidentified PVL-negative ST5-IV spa t002 clone replaced the PVL-positive ST30-IV Southwest Pacific clone as the dominant CA-MRSA clone. Of particular concern was the finding of several successful and virulent MRSA clones from other geographic settings, including ST93-IV (Queensland CA-MRSA), ST8-IV (USA300) and ST772-V (Bengal Bay MRSA). Ongoing molecular surveillance is essential to prevent these MRSA strains becoming endemic in the New Zealand healthcare setting
