    Abstract: As an ecotone, the region between the Amazon Rainforest and Tropical Savanna (Cerrado) biomes is, by definition, more susceptible to climate change. Therefore, understanding palaeoenvironmental dynamics is essential to address the future responses of such transition areas to climatic fluctuations. In this context, we present a new sediment record for the Late-Holocene retrieved from Barro-Preto, currently an oxbow lake located in an ecotone at the southern Brazilian Amazon border. Our multi-proxy data include carbon and nitrogen isotopes, as well as bulk TOC, chlorophyll derivatives, grain-size and microcharcoal analyses, all anchored on a radiocarbon-dated chronology. The sedimentary process recorded at the Barro-Preto Lake responded to both local and regional climate dynamics. It was influenced by river excursions associated to local responses to precipitation changes by the activation of the palaeochannel connecting the main-stem river and the Barro-Preto lake. This activation was evidenced by the presence of different colour lithology laminations accompanied by coarser sediments and also by climate conditions known to influence the Amazon region. Depositional processes linked to lake dynamics and different oxbow lake cycle stages were also important to explain the changes verified in the Barro-Preto record, endorsing the use of this lake formation for palaeoclimatic reconstructions. The record indicated a rising humidity trend, reflected by a progressive increase in lacustrine productivity, in accordance to other studies carried out in the Amazon region concerning the Late-Holocene, associated with a more southward displacement of the Intertropical Convergence Zone. Despite this rising humidity trend, dry episodic events during the Late-Holocene were evidenced by charcoal data, also coherent with regional Amazon studies, albeit exhibiting increased intensity, suggesting that the transitional nature of the environment might have influenced susceptibility to fires.

    Abstract: Trans women are specifically vulnerable to interpersonal violence. Being perceived as the gender that a transgender person identifies with, defined in some contexts as passing, may influence violence ratings. The EVAS (Violence and Health Self-Evaluation) study was a cross-sectional study that enrolled 121 trans women between 2019 and 2020 in Rio de Janeiro, Brazil, aiming to investigate the association between self-reported passing and different types of interpersonal violence. We enrolled 121 participants who had a median age of 36.3 (interquartile range [IQR] 13.7). Most of them were Black/mixed (78.5%) and had at least a high school education (63%). Most participants considered themselves as trans women (71.9%). Their median monthly income was $252.50 (IQR $302.50). Only 40 (33.1%) trans women had a main partner. Trans women with high passing had a higher prevalence of family violence and lower prevalence of observed police violence, violence in open and closed public spaces. Participants that reported a high passing had higher prevalence of family violence (p = .016); moreover, they reported observing less frequently police violence in the neighborhood they lived in for the last 12 months (p = .012) as well as having lower rates of suffering violence. Trans women who reported high passing had 81% (56%-92%) lower chance of suffering violence in open public places more than once, while prior racism experience had a positive association with violence in an open public place (aOR = 3.93, 95% CI [.48, 15.40] ). Passing seems to protect from violence in public spaces, whilst it increases family violence. Data also suggest that observing police violence and violence in close public spaces. There is an urgent need to better understand the complex relationships around violence and foster its prevention.

    Effect of Transcranial Direct Current Stimulation on Professional Female Soccer Players’ Recovery Following Official Matches

    Abstract: This study investigated the effect of transcranial direct current stimulation (tDCS) combined with a recovery training session on the well-being and self-perceived recovery of professional female soccer players after official matches. Data from 13 world-class players were analyzed after participating in four official soccer matches of the first division of the Brazilian Women’s Soccer Championship (7-, 10-, and 13-day intervals). We applied anodal tDCS (a-tDCS) over the left dorsolateral prefrontal cortex with 2 mA for 20 minutes (+F3/−F4 montage) the day after each match. Participants underwent two randomly ordered sessions of a-tDCS or sham. Players completed the Well-Being Questionnaire (WBQ) and the Total Quality Recovery (TQR) scale before each experimental condition and again the following morning. A two-way repeated-measures ANOVA showed a significant time x condition interaction on the WBQ (F (1,11) =5.21; p=0.043; η p 2 =0.32), but not on the TQR (F (1,12)  = 0.552; p = 0.47; η p 2  = 0.044). There was a large effect size (ES) for a-tDCS for the WBQ score (ES = 1.02; 95%CI = 0.17;1.88), and there was a moderate WBQ score increase (ES = 0.53; 95%CI = −0.29;1.34) for the sham condition. We found similar increases in the TQR score for a-tDCS (ES = 1.50; 95%CI = 0.63–2.37) and the sham condition (ES = 1.36; 95%CI = 0.51–2.22). These results suggest that a-tDCS (+F3/−F4 montage) combined with a recovery training session may slightly improve perceived well-being beyond the level of improvement after only the recovery training session among world-class female soccer players. Prior to widely adopting this recovery approach, further study is needed with larger and more diverse samples, including for female teams of different performance levels.
