Sub-arcsec Observations of NGC 7538 IRS 1: Continuum Distribution and Dynamics of Molecular Gas

We report new results based on the analysis of the SMA and CARMA observations of NGC 7538\,IRS\,1 at 1.3 and 3.4 mm with sub-arcsec resolutions. With angular resolutions $\sim$ 0\farcs7, the SMA and CARMA observations show that the continuum emission at 1.3 and 3.4 mm from the hyper-compact \ion{H}{2} region IRS\,1 is dominated by a compact source with a tail-like extended structure to the southwest of IRS\,1. With a CARMA B-array image at 1.3 mm convolved to 0\farcs1, we resolve the hyper-compact \ion{H}{2} region into two components: an unresolved hyper-compact core, and a north-south extension with linear sizes of $<270$ AU and $\sim$2000 AU, respectively. The fine structure observed with CARMA is in good agreement with the previous VLA results at centimeter wavelengths, suggesting that the hyper-compact \ion{H}{2} region at the center of IRS\,1 is associated with an ionized bipolar outflow. We image the molecular lines OCS(19-18) and CH$_3$CN(12-11) as well as $^{13}$CO(2-1) surrounding IRS\,1, showing a velocity gradient along the southwest-northeast direction. The spectral line profiles in $^{13}$CO(2-1), CO(2-1), and HCN(1-0) observed toward IRS\,1 show broad redshifted absorption, providing evidence for gas infall with rates in the range of $3-10\times10^{-3}$ M$_\odot$ yr$^{-1}$ inferred from our observations.Comment: 19 pages, 14 figure

Anxious Emotions Lead to Anxious Solutions? Examining the Relationships Between Emotions, Alcohol Consumption, and Consent

College students report several motives for alcohol consumption when engaging in hookups including: social enhancement, conformity, and coping with unwanted anxious emotions (Lobby et al., 2019). Research is currently mixed about how alcohol impacts sexual consent, and how emotions may drive these factors (Lobby et al., 2019; Marcantonio and Jozkowski, 2021). Socially-oriented anxious emotions, such as nervousness and insecurity, decrease when drinking alcohol in a social setting, and some college students report that alcohol consumption may be habitual prior to attending social events in order to relieve anxiety, a practice known as “pre-gaming” (Blumenthal et al., 2010). Additionally, alcohol consumption may be interpreted as a cue for consent by a prospective sexual partner, leading to decreased verbal consent (Blumenthal et al., 2010). Whether or not socially-oriented anxious emotions are a moderator for alcohol consumption\u27s role in navigating consent in a hookup, or what role these emotions play in relation to alcohol consumption and sexual consent, are not well understood. The current study aims to examine the relationships between anxious emotions, level of alcohol consumption, and the ability to consent. Two surveys were released to a mid-sized northeastern university in 2020 and 2021. Participants (N = 453) completed online questionnaires using Qualtrics software. Researchers analyzed five questions from the survey related to anxious emotions, motivations for and levels of alcohol consumption, and perceptions of consent. Researchers analyzed the data using SPSS software, testing the relationships between alcohol consumption, consent, and anxious emotions. Results have implications for university sexual assault prevention and policy.https://orb.binghamton.edu/research_days_posters_2022/1108/thumbnail.jp

Socially Communicative Eye Contact and Gender Affect Memory

Because of their value as a socially communicative cue, researchers have strived to understand how the gaze of other people influences a variety of cognitive processes. Recent work in social attention suggests that the use of images of people in laboratory studies, as a substitute for real people, may not effectively test socially communicative aspects of eye gaze. As attention affects many other cognitive processes, it is likely that social attention between real individuals could also affect other cognitive processes, such as memory. However, from previous work alone, it is unclear whether, and if so how, socially communicative eye gaze affects memory. The present studies test the assumption that socially communicative aspects of eye gaze may impact memory by manipulating the eye gaze of a live speaker in the context of a traditional recognition paradigm used frequently in the laboratory. A female (Experiment 1) or male (Experiment 2) investigator read words aloud and varied whether eye contact was, or was not, made with a participant. With both female and male investigators, eye contact improved word recognition only for female participants and hindered word recognition in male participants. When a female investigator prolonged their eye contact (Experiment 3) to provide a longer opportunity to both observe and process the investigator’s eye gaze, the results replicated the findings from Experiments 1 and 2. The findings from Experiments 1–3 suggest that females interpret and use the investigator’s eye gaze differently than males. When key aspects from the previous experiments were replicated in a noncommunicative situation (i.e., when a video of a speaker is used instead of a live speaker; Experiment 4), the memory effects observed previously in response to eye gaze were eliminated. Together, these studies suggest that it is the socially communicative aspects of eye gaze from a real person that influence memory. The findings reveal the importance of using social cues that are communicative in nature (e.g., real people) when studying the relationship between social attention and memory

Assembling sustainable ideas: The construction process of the proposal SMLsystem at the Solar Decathlon Europe 2012

[EN] The innovation of the construction process in SMLsystem lies in an evolution of the way of thinking the sustainable architecture. The key is that SMLsystem proposal is not constructed but is assembled. This way, it is designed with prefabricated and industrialized elements which allow themselves to connect as in a plug and play process in order to reduce the risks and save time and costs consequently. About that, the study and design of the junction has been another interesting issue to solve the assembly of the modules, focusing on factors like the isolation and the rainwater always present. In addition this proposal shows a new way in the use of wood as a structural material, as a building enclosure and as a dynamic system of solar protection, all of them as a result of the combination of various premises inherent to the concept of the project like the respect for the environment, recycling or sustainability and, of course, with an absolute integration with the architectural design. This way, the complete development of SMLsystem has had the capacity of defining a global project which reflects the primal ideas: design, sustainability, modularity, flexibility and prefabrication. © 2014 Elsevier B.V.
