Attitudes to ageing and objectively-measured sedentary and walking behaviour in older people: the Lothian Birth Cohort 1936

Background:Prolonged sitting and low activity—both common in older people—are associated with increased mortality and poorer health. Whether having a more negative attitude to ageing is associated with higher levels of these behaviours is unclear.Objective:We investigated the prospective relationship between attitudes to ageing and objectively measured sedentary and walking behaviour.Methods:Participants were 271 members of the Lothian Birth Cohort 1936. At age 72 years, participants completed the Attitudes to Ageing Questionnaire which assesses attitudes on three domains—Psychosocial loss, Physical change and Psychological growth. At age 79 years, participants wore an activPAL activity monitor for seven days. The outcome measures were average daily time spent sedentary, number of sit-to-stand transitions, and step count.Results:There were no significant associations between any of the Attitude to Ageing domain scores and time spent sedentary or number of sit-to-stand transitions. In sex-adjusted analysis, having a more positive attitude to ageing as regards Physical change was associated with a slightly higher daily step count, for a SD increment in score, average daily step count was greater by 1.5% (95% CI 0.6%, 2.4%). On further adjustment for potential confounding factors these associations were no longer significant.Conclusion:We found no evidence that attitudes to ageing at age 72 were predictive of sedentary or walking behaviour seven years later. Future studies should examine whether attitudes to ageing are associated with objectively measured walking or sedentary behaviour at the same point in time. The existence of such an association could inform the development of interventions.<br/

Tan(beta) enhanced Yukawa couplings for supersymmetric Higgs singlets at one loop

Extensions of the MSSM generically feature gauge singlet Higgs bosons. These singlet Higgs bosons have tan(beta)-enhanced Yukawa couplings to down-type quarks and leptons at the one-loop level. We present an effective Lagrangian incorporating these Yukawa couplings and use it to study their effect on singlet Higgs boson phenomenology within both the mnSSM and NMSSM. It is found that the loop-induced couplings represent an appreciable effect for the singlet pseudoscalar in particular, and may dominate its decay modes in some regions of parameter space.Comment: Submitted for the SUSY07 proceedings, 4 pages, 5 figure

Aeromonas detection and their toxins from drinking water form reservoirs and drinking fountains

Aeromonads are inhabitants of aquatic ecosystems and are described as being involved in intestinal disturbances and other infections. A total of 200 drinking water samples from domestic and public reservoirs and drinking fountains located in São Paulo (Brazil), were analyzed for the presence of Aeromonas. Samples were concentrated by membrane filtration and enriched in APW. ADA medium was used for Aeromonas isolation and colonies were confirmed by biochemical characterization. Strains isolated were tested for hemolysin and toxin production. Aeromonas was detected in 12 samples (6.0%). Aeromonas strains (96) were isolated and identified as: A. caviae (41.7%), A. hydrophila (15.7%), A.allosacharophila (10.4%), A. schubertii (1.0%) and Aeromonas spp. (31.2%).The results revealed that 70% of A. caviae, 66.7% of A. hydrophila, 80% of A. allosacharophila and 46.6% of Aeromonas spp. were hemolytic. The assay for checking production of toxins showed that 17.5% of A. caviae, 73.3% of A. hydrophila, 60% of A. allosacharophila, 100% of A. schubertii, and 33.3% of Aeromonas spp. were able to produce toxins. The results demonstrated the pathogenic potential of Aeromonas, indicating that the presence of this emerging pathogen in water systems is a public health concer

BRAZIL'S AMAZON TO THE WORLD: PRESIDENT BOLSONARO'S DISCOURSE AT THE UNITED NATIONS GENERAL ASSEMBLY

This paper analyzes the discourse on the Amazon of Brazil's president Bolsonaro at the UN General Assembly in 2020. The objective is to observe how the region has been integrated into the federal political agenda and the discursive strategies marked by “disinformation" adopted by Brazil's chief executive. We use the three-dimensional assumptions of Critical Discourse Analysis. Brazil’s president promoted inaccurate data, made unfounded statements, victimized himself, and kept silent about negative information related to his management. He sought to promote a distorted view on environmental management and on the Amazonian reality, putting the effective protection of the region at risk.

THE MASQUERADE: HUMOR, REALITY AND FICTION IN HENRY FIELDING’S WORKS

The eighteenth century was a decisive period for the rise and consolidation of the English novel. Considering Henry Fielding’s (1707-1754) importance in such process, this article aims to analyze the relationship between fiction and reality in some of his works — with emphasis on Joseph Andrews (1742) and its preface, but also considering Shamela (1741) and Tom Jones (1749). For such relationship, the construction of humor or comic is crucial, because the affectation is, in Fielding's view, the only source of the true ridiculousness present in the world. It is through affectation that fiction and reality come together in their idiosyncrasies and interpenetrations, which allows Fielding to subvert and raise to absurdity the quest for factuality that was common to novels at the time.DOI: https://doi.org/10.47295/mgren.v8i2.201
