Subjective self-assessment of physical activity is negatively affected by monitoring awareness in subjects with mild cognitive impairment : A crossover randomised controlled trial

Publisher Copyright: © 2021 Verduci Editore s.r.l. All rights reserved.OBJECTIVE: Physical activity plays an important role in maintaining mental and physical health. This study assessed the effect of physical activity monitoring awareness on the physical activity level and subjective self-assessment of physical activity in middle-aged subjects with normal cognitive function (NCF) and mild cognitive impairment (MCI). PATIENTS AND METHODS: Thirty-five subjects aged 50-65 years with NCF and MCI were randomised into two experimental groups, each taking part in two one-week intervention periods. Subjects in group A were not aware that their physical activity was monitored in the first week (phase I) and were aware of the monitoring in the second week (phase II), whereas it was the opposite order for group B. Physical activity was assessed using the ActiGraph GT9X accelerometer and International Physical Activity Questionnaire (IPAQ). RESULTS: A total of 32 subjects (MCI: n = 12, NCF: n = 20) completed both intervention periods, with MCI subjects having significantly lower objectively assessed physical activity than NCF participants. Moreover, subjectively assessed physical activity in the MCI group was significantly higher when the participants were unaware of physical activity monitoring. A significant phase-group interaction was found in total (MET-min/d: P = 0.0072; min/d: P = 0.0194) and moderate (MET-min/d: P = 0.0015; min/d: P = 0.0020) physical activity as well as energy expenditure (p = 0.0366) assessed by the IPAQ and in the percentage of sedentary behaviour (p = 0.0330) and the average number of steps (p = 0.0342) assessed by ActiGraph. CONCLUSIONS: The awareness of physical activity assessment might decrease the ability to subjectively assess physical activity in subjects with MCI.Peer reviewe

Cross-Cultural Sexism and the Effectiveness of Gender (Non)Traditional Advertising: A Comparison of Purchase Intentions in Poland, South Africa, and the United Kingdom.

Findings regarding the effectiveness of (non)traditionally gendered advertisements are mixed and largely emanate from the United States. We tested the stereotype content model and ambivalent sexism theory cross-nationally in an advertising context and predicted that paternalistic (vs. envious) female stereotypes will trigger higher purchase intent (PI) irrespective of country (Hypothesis 1), viewers’ benevolent sexism will positively predict PI for paternalistic housewife advertisements (Hypothesis 2a), viewers’ hostile sexism will negatively predict PI for envious businesswoman advertisements (Hypothesis 2b), and these relationships with sexism will be confined to less gender egalitarian countries (i.e., Poland and South Africa) (Hypothesis 3). Statistical analyses of data from 468 Polish, South African, and British university students supported Hypothesis 1 and partially supported Hypotheses 2 and 3. The predicted patterns held for South Africa, but in Poland, viewers’ benevolence positively predicted PI for both advertisement types, with the exception of highly hostile women. British viewers’ hostility positively predicted PI for the housewife advertisement. Our findings support the cross-cultural applicability of the stereotype content model to advertising and suggest that the predictive role of sexism changes depending on its type, advertisement type, country, and gender. We recommend that advertisers should adopt a nuanced approach in predicting the effectiveness of gendered advertisements

Beam energy dependent two-pion interferometry and the freeze-out eccentricity of pions in heavy ion collisions at STAR

We present results of analyses of two-pion interferometry in Au+Au collisions at $\sqrt{s_{NN}}$ = 7.7, 11.5, 19.6, 27, 39, 62.4 and 200 GeV measured in the STAR detector as part of the RHIC Beam Energy Scan program. The extracted correlation lengths (HBT radii) are studied as a function of beam energy, azimuthal angle relative to the reaction plane, centrality, and transverse mass ($m_{T}$) of the particles. The azimuthal analysis allows extraction of the eccentricity of the entire fireball at kinetic freeze-out. The energy dependence of this observable is expected to be sensitive to changes in the equation of state. A new global fit method is studied as an alternate method to directly measure the parameters in the azimuthal analysis. The eccentricity shows a monotonic decrease with beam energy that is qualitatively consistent with the trend from all model predictions and quantitatively consistent with a hadronic transport model.Comment: 27 pages; 27 figure

Beam-energy dependence of charge separation along the magnetic field in Au+Au collisions at RHIC

Local parity-odd domains are theorized to form inside a Quark-Gluon-Plasma (QGP) which has been produced in high-energy heavy-ion collisions. The local parity-odd domains manifest themselves as charge separation along the magnetic field axis via the chiral magnetic effect (CME). The experimental observation of charge separation has previously been reported for heavy-ion collisions at the top RHIC energies. In this paper, we present the results of the beam-energy dependence of the charge correlations in Au+Au collisions at midrapidity for center-of-mass energies of 7.7, 11.5, 19.6, 27, 39 and 62.4 GeV from the STAR experiment. After background subtraction, the signal gradually reduces with decreased beam energy, and tends to vanish by 7.7 GeV. The implications of these results for the CME will be discussed.Comment: 6 pages, 4 figures, accepted by Phys. Rev. Lett (more model comparisons have been added in version 2

Observation of D0D^0 meson nuclear modifications in Au+Au collisions at sNN\sqrt{s_{_{\mathrm{NN}}}} = 200 GeV

We report the first measurement of charmed-hadron ($D^0$) production via the hadronic decay channel ($D^0\rightarrow K^- + \pi^+$) in Au+Au collisions at $\sqrt{s_{_{\mathrm{NN}}}}$ = 200\,GeV with the STAR experiment. The charm production cross-section per nucleon-nucleon collision at mid-rapidity scales with the number of binary collisions, $N_{bin}$, from $p$+$p$ to central Au+Au collisions. The $D^0$ meson yields in central Au+Au collisions are strongly suppressed compared to those in $p$+$p$ scaled by $N_{bin}$, for transverse momenta $p_{T}>3$ GeV/$c$, demonstrating significant energy loss of charm quarks in the hot and dense medium. An enhancement at intermediate $p_{T}$ is also observed. Model calculations including strong charm-medium interactions and coalescence hadronization describe our measurements.Comment: 7 pages including author list, 4 figures, submit to PRL with revised versio

Measurement of longitudinal spin asymmetries for weak boson production in polarized proton-proton collisions at RHIC

We report measurements of single- and double- spin asymmetries for $W^{\pm}$ and $Z/\gamma^*$ boson production in longitudinally polarized $p+p$ collisions at $\sqrt{s} = 510$ GeV by the STAR experiment at RHIC. The asymmetries for $W^{\pm}$ were measured as a function of the decay lepton pseudorapidity, which provides a theoretically clean probe of the proton's polarized quark distributions at the scale of the $W$ mass. The results are compared to theoretical predictions, constrained by recent polarized deep inelastic scattering measurements, and show a preference for a sizable, positive up antiquark polarization in the range $0.05<x<0.2$.Comment: 7 pages, 5 figures, Submitted to Physical Review Letters; replaced with published versio

Precision Measurement of the Longitudinal Double-spin Asymmetry for Inclusive Jet Production in Polarized Proton Collisions at s=200\sqrt{s}=200 GeV

We report a new high-precision measurement of the mid-rapidity inclusive jet longitudinal double-spin asymmetry, $A_{LL}$, in polarized $pp$ collisions at center-of-mass energy $\sqrt{s}=200$ GeV. The STAR data place stringent constraints on polarized parton distribution functions extracted at next-to-leading order from global analyses of inclusive deep inelastic scattering (DIS), semi-inclusive DIS, and RHIC $pp$ data. The measured asymmetries provide evidence for positive gluon polarization in the Bjorken-$x$ region $x>0.05$.Comment: 7 pages, 3 figure
