Comparing Comparatives in Artificial Languages / Komparado de komparativoj en artefaritaj lingvoj

It is possible to classify Artificial Languages as well as Natural Languages into three main types, according to the forms of comparative adjectives. Artificial Languages can form the comparatives using only a synthetic strategy, or only an analytic strategy, or both of them accordingly. Artificial Languages that use only a syntetic strategy can be classified further according to the rules in choosing one strategy or the other. Some evidence shows that a large proportion of Artificial Languages have both analytic and synthetic comparatives, as in some natural languages. The formation of comparatives results to be an interesting area of morphology, where there is room for choice, also for Artificial Languages. Eblas klasifiki artefaritajn kaj naturajn lingvojn laŭ tri tipoj, depende al la formoj de komparativaj adjektivoj. Artefaritaj lingvoj povas formi komparativojn uzante nur sintezajn formojn, nur analizajn formojn, aŭ ambaŭ formojn laŭkaze. Artefaritajn lingvojn kiuj uzas nur sintezan strategion oni povas klasifiki plue per la reguloj elekti unu aŭ la alian strategion. Ia evidenco montras, ke granda parto de artefaritaj lingvoj havas ambaŭ analizan kaj sintezan komparativojn, kiel en kelkaj naturaj lingvoj. La formado de komparativoj rezultas esti interesa areo de morfologio, en kiu eblas elekti, eĉ kaze de artefaritaj lingvoj

On conversational valence and the definition of interjections

Interjections, like some other word classes, have proven difficult to define in a principled way, and therefore there has been disagreement about whether some words belong to this class. Lists of interjections in grammars sometimes include arguably disparate items, e.g. greeting terms, along with words such as oh and ah. There has also been dispute about the possibility or necessity for interjections to be in a syntactic relation to other components, that is, about their valence. In this paper I propose a definition of interjection which involves an extension of valence in the usual syntactic sense, introducing the notion of conversational valence to distinguish between interjections and words such as goodbye. The latter can only be felicitously used when there is an addressee present, as well as the speaker, thus having a conversational valence of 2, while interjections do not require an addressee, i.e. their conversational valence is 1. For example, if I stub my toe I can appropriately say ouch! in the absence of anyone else. Interjections are distinguished by being the only linguistic items with such a low conversational valence.ANU College of Arts & Social Sciences, School of Language Studies; ANU College of Asia and the Pacific, School of Culture, History and Languag

Managing virtual rapport on Tripadvisor: discourse in hotel responses to negative online reviews

Digital technology has immensely transformed communication, and social media facilitates online feedback mechanisms, empowering consumers’ voices via online reviews. This has led to the pervasively growing influence of electronic word of mouth (eWOM) on customers’ purchase intentions, as negative online reviews can be detrimental to business performance. Therefore, digital business engagement on online platforms is essential to ensure customer satisfaction and manage online reputation. Building on Spencer-Oatey’s (2008) Rapport Management Model (RMM), this qualitative study explores the rapport management strategies used by eighteen Malaysian five-, four- and three-star hotels to respond to negative online reviews, from the perspective of the RMM discourse domain. The hotel responses were collected from TripAdvisor, using purposeful sampling and analysed with Computer-Mediated Discourse Analysis. The findings show that the five- and four-star hotels employed higher frequencies of moves in their responses to complaints in negative reviews. Some four- and three-star hotels took a more confrontational approach by using the sub-move ‘denying problems’. In terms of RMM rapport orientation, this sub-move can be rapport-challenging in customer relationships. This study highlights that managing negative reviews more efficiently for service recovery on online platforms is essential to maintain customer relationships and establish a positive online corporate reputation. More generally, the findings provide insights on cultural rapport management strategies used in one Southeast Asian country—Malaysia

The \u2018COmorBidity in Relation to AIDS\u2019 (COBRA) cohort: Design, methods and participant characteristics

Background Persons living with HIV on combination antiretroviral therapy (cART) may be at increased risk of the development of age-associated non-communicable comorbidities (AANCC) at relatively young age. It has therefore been hypothesised that such individuals, despite effective cART, may be prone to accelerated aging. Objective The COmorBidity in Relation to AIDS (COBRA) cohort study was designed to investigate the potential causal link between HIV and AANCC, amongst others, in a cohort of middle-aged individuals with HIV with sustained viral suppression on cART and otherwise comparable HIV-negative controls. Methods Longitudinal cohort study of HIV-positive subjects 45 years of age, with sustained HIV suppression on cART recruited from two large European HIV treatment centres and similarly-aged HIV-negative controls recruited from sexual health centres and targeted community groups. Both HIV-positive and HIV-negative subjects were assessed at study entry and again at follow-up after 2 years. Results Of the 134 HIV-positive individuals with a median (IQR) age of 56 (51, 62) years recruited, 93% were male, 88% of white ethnicity and 86% were men who have sex with men (MSM). Similarly, the 79 HIV-negative subjects had a median (IQR) age of 57 (52, 64) and 92% were male, 97% of white ethnicity and 80% were MSM. Conclusions The results from the COBRA study will be a significant resource to understand the link between HIV and AANCC and the pathogenic mechanisms underlying this link. COBRA will inform future development of novel prognostic tools for earlier diagnosis of AANCC and of novel interventions which, as an adjunct to cART, may prevent AANCC

Increased brain-predicted aging in treated HIV disease

Objective: To establish whether HIV disease is associated with abnormal levels of age-related brain atrophy, by estimating apparent brain age using neuroimaging and exploring whether these estimates related to HIV status, age, cognitive performance, and HIV-related clinical parameters. Methods: A large sample of virologically suppressed HIV-positive adults (n = 162, age 45-82 years) and highly comparable HIV-negative controls (n = 105) were recruited as part of the Comorbidity in Relation to AIDS (COBRA) collaboration. Using T1-weighted MRI scans, a machinelearning model of healthy brain aging was defined in an independent cohort (n = 2,001, aged 1890 years). Neuroimaging data from HIV-positive and HIV-negative individuals were then used to estimate brain-predicted age; then brain-predicted age difference (brain-PAD 5 brain-predicted brain age 2 chronological age) scores were calculated. Neuropsychological and clinical assessments were also carried out. Results: HIV-positive individuals had greater brain-PAD score (mean +/- SD 2.15 +/- 7.79 years) compared to HIV-negative individuals (20.87 +/- 8.40 years; b = 3.48, p < 0.01). Increased brainPAD score was associated with decreased performance in multiple cognitive domains (information processing speed, executive function, memory) and general cognitive performance across all participants. Brain-PAD score was not associated with age, duration of HIV infection, or other HIV-related measures. Conclusion: Increased apparent brain aging, predicted using neuroimaging, was observed in HIV-positive adults, despite effective viral suppression. Furthermore, the magnitude of increased apparent brain aging related to cognitive deficits. However, predicted brain age difference did not correlate with chronological age or duration of HIV infection, suggesting that HIV disease may accentuate rather than accelerate brain aging

Análise da implantação do sistema de gestão dos resíduos sólidos recicláveis na Vila das Peças, Guaraqueçaba, Paraná, Brasil

Objectives: Despite successful antiretroviral therapy, people living with HIV (PLWH) may show signs of premature/accentuated aging. We compared established biomarkers of aging in PLWH, appropriately chosen HIV-negative individuals, and blood donors, and explored factors associated with biological age advancement. Design: Cross-sectional analysis of 134 PLWH on suppressive antiretroviral therapy, 79 lifestyle-comparable HIV-negative controls aged 45 years or older from the Co-morBidity in Relation to AIDS (COBRA) cohort, and 35 age-matched blood donors. Methods: Biological age was estimated using a validated algorithm based on 10 biomarkers. Associations between ` age advancement' (biological minus chronological age) and HIV status/ parameters, lifestyle, cytomegalovirus (CMV), hepatitis B (HBV) and hepatitis C virus (HCV) infections were investigated using linear regression. Results: The average (95% CI) age advancement was greater in both HIV-positive [13.2 (11.6-14.9) years] and HIV-negative [5.5 (3.8-7.2) years] COBRA participants compared with blood donors [-7.0 (-4.1 to -9.9) years, both P's< 0.001)], but also in HIV-positive compared with HIV-negative participants (P< 0.001). Chronic HBV, higher anti-CMV IgG titer and CD8 thorn T-cell count were each associated with increased age advancement, independently of HIV-status/ group. Among HIV-positive participants, age advancement was increased by 3.5 (0.1-6.8) years among those with nadir CD4 thorn T-cell count less than 200 cells/ ml and by 0.1 (0.06-0.2) years for each additional month of exposure to saquinavir. Conclusion: Both treated PLWH and lifestyle-comparable HIV-negative individuals show signs of age advancement compared with blood donors, to which persistent CMV, HBV co-infection and CD8(+) T-cell activation may have contributed. Age advancement remained greatest in PLWH and was related to prior immunodeficiency and cumulative saquinavir exposure

Validation of a Novel Multivariate Method of Defining HIV-Associated Cognitive Impairment

Background. The optimum method of defining cognitive impairment in virally suppressed people living with HIV is unknown. We evaluated the relationships between cognitive impairment, including using a novel multivariate method (NMM), patientreported outcome measures (PROMs), and neuroimaging markers of brain structure across 3 cohorts.Methods. Differences in the prevalence of cognitive impairment, PROMs, and neuroimaging data from the COBRA, CHARTER, and POPPY cohorts (total n = 908) were determined between HIV-positive participants with and without cognitive impairment defined using the HIV-associated neurocognitive disorders (HAND), global deficit score (GDS), and NMM criteria.Results. The prevalence of cognitive impairment varied by up to 27% between methods used to define impairment (eg, 48% for HAND vs 21% for NMM in the CHARTER study). Associations between objective cognitive impairment and subjective cognitive complaints generally were weak. Physical and mental health summary scores (SF-36) were lowest for NMM-defined impairment (P&lt;.05). There were no differences in brain volumes or cortical thickness between participants with and without cognitive impairment defined using the HAND and GDS measures. In contrast, those identified with cognitive impairment by the NMM had reduced mean cortical thickness in both hemispheres (P&lt;.05), as well as smaller brain volumes (P&lt;.01). The associations with measures of white matter microstructure and brain-predicted age generally were weaker.Conclusion. Different methods of defining cognitive impairment identify different people with varying symptomatology and measures of brain injury. Overall, NMM-defined impairment was associated with most neuroimaging abnormalities and poorer selfreported health status. This may be due to the statistical advantage of using a multivariate approach
