Piecing Together the American Voting Puzzle: How VotersĂą Personalities and Judgments of Issue Importance Mattered in the 2016 Presidential Election
In the wake of the 2016 election, which surprised pundits and voters on both the left and the right, there has been renewed interest in understanding what predicts American votersĂą choices. In this article, we investigate the roles of personality and issue importance in how people voted in the 2016 U.S. election. In this longitudinal study of 403 MTurk workers who voted in the election, we assessed the relations between personality (openness, social dominance orientation, and national identity importance) and issue importance (group rights and social justice, economic rights, and individual and national rights), and voting for Clinton or Trump. Our results indicate that both individual differences and issue importance as measured in July 2016 predicted votes in November. We also found that the links between personality and voting were mediated by issue importance. Implications for political psychology and the study of personality, campaign issues, and voting behavior are discussed.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/146841/1/asap12157.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/146841/2/asap12157_am.pd
Bioassay-guided isolation and identification of antimicrobial compounds from thyme essential oil by means of overpressured layer chromatography, bioautography and GC-MS
A simple method is described for efficient isolation of compounds having an antibacterial effect.
Two thyme (Thymus vulgaris) essential oils, obtained from the market, were chosen as
prospective materials likely to feature several bioactive components when examined by thin layer
chromatography coupled with direct bioautography as a screening method. The newly developed
infusion overpressured layer chromatographic separation method coupled with direct
bioautography assured that only the active components were isolated by means of overrun
overpressured layer chromatography with online detection and fractionation. Each of the 5
collected fractions represented one of the five antimicrobial essential oil components designated
at the screening. The purity and the activity of the fractions were confirmed with chromatography
coupled various detection methods (UV, vanillin-sulphuric acid reagent, direct bioautography).
The antibacterial components were identified with GC-MS as thymol, carvacrol, linalool, diethylphthalate,
and alpha-terpineol. The oil component diethyl-phthalate is an artificial compound,
used as plasticizer or detergent bases in the industry. Our results support that exploiting its
flexibility and the possible hyphenations, overpressured layer chromatography is especially
attractive for isolation of antimicrobial components from various matrixes
An exploration and proposed taxonomy of leisureâbefriending for adults with learning disabilities
© 2019 The Authors. British Journal of Learning Disabilities Published by John Wiley & Sons Ltd Taking part in leisure activities is beneficial, yet many adults with learning disabilities are unable to participate in their preferred activities because of cost, because not having anyone to go with or because they do not feel welcome. Befriending is where someone volunteers to act as a friend. Befriending may be a way for adults with learning disabilities to participate in leisure activities with someone who is not a paid carer or family. The author spent time with four people with learning disabilities and their befrienders to find out what things they do together and what they both get from it. Friends and family members were also interviewed. Participants enjoyed the time they spent together. However, they often did the same activities they would do with paid carers or family and the relationship was sometimes quite professional. Befriending could be a way for adults with learning disabilities to have new, beneficial experiences, but we need to know more about how relationships work. Abstract: Background Leisure time for adults with learning disabilities is often diversionary and spent doing passive, solitary or family-orientated activities. Befriending, as a hybrid ânaturalâ support, may help adults with learning disabilities overcome the barriers to participation in nonsegregated leisure. Materials and methods Four case studies of pairs of âbefriendersâ and âbefriendeesâ were recruited purposively. Participant observation was carried out with each case, followed by semi-structured interviews with participants and relevant stakeholders. Data were analysed using thematic analysis. Results Befriending activities were mostly limited to enjoyable yet âcasualâ leisure activities that adults with learning disabilities might already participate in with family and paid service providers. Negotiating the befriender role between friend and professional was an ongoing challenge. Conclusions Outcomes of leisureâbefriending relationships for adults with learning disabilities are linked to both the nature of relationships and the types of activities undertaken. There are four proposed ideal types of leisureâbefriending relationship, yet repeating familiar âcasualâ leisure activities means adults with learning disabilities risk missing out on novel leisure and social experiences
Chronic recurrent Gorham-Stout syndrome with cutaneous involvement
Type IV osteolysis or Gorham-Stout syndrome is a rare condition characterized by recurrent vascular tumors that disrupt normal anatomical architecture. Gorham-Stout syndrome is most commonly associated with the skeletal system with resulting replacement of bone with scar tissue following tumor regression. The loss of entire bones has given Gorham-Stout syndrome the moniker vanishing bone disease. Natural progression of Gorham-Stout syndrome is characterized by spontaneous disease resolution. However, rare variants of recurrent, progressive, and/or systemic disease have been reported. We present a patient with a history of recurrent Gorham- Stout disease refractory to all treatment options considered. In addition to skeletal disease, our patient had soft tissue and cutaneous involvement, thus reflecting the more aggressive disease variant. Previous surgical attempts to control disease had been ineffective and the patient was referred to us for radiation therapy. Treatment with external beam radiation therapy resulted in good local control and symptom palliation, but full disease resolution was never accomplished. In addition to presentation of this patient, a review of the literature on etiological hypotheses and past/future treatment options was conducted and is included
The person-based nature of prejudice: Individual difference predictors of intergroup negativity
Person-based factors influence a range of meaningful life outcomes, including intergroup processes, and have long been implicated in explaining prejudice. In addition to demonstrating significant heritability, person-based factors are evident in expressions of generalised prejudice, a robust finding that some people (relative to others) consistently score higher in prejudice towards multiple outgroups. Our contemporary review includes personality factors, ideological orientations (e.g., authoritarianism), religiosity, anxiety, threat, disgust sensitivity, and cognitive abilities and styles. Meta-analytic syntheses demonstrate that such constructs consistently predict prejudice, often at the upper bounds of effect sizes observed in psychological research. We conclude that prejudice theories need to better integrate person- and situation-based factors, including their interaction, to capture the complexity of prejudice and inform intervention development
I read it on reddit: Exploring the role of online communities in the 2016 US elections news cycle
Reddit has developed into a significant platform for political discussion among Millennials. In this exploratory study, we examine subscription trends on three political sub-forums on Reddit during the 2016 US presidential elections: /The_Donald, /SandersForPresident, and /HillaryClinton. As a theoretical framework, we draw from work on online communitiesâ group identity and cohesion. Concretely, we investigate how subscription dynamics relate to positive, negative and neutral news events occurring during the election cycle. We classify news events using a sentiment analysis of event-related news headlines. We observe that users who supported Sanders displayed no consolidation of support for Clinton after she won the Democratic Partyâs presidential nomination. Secondly, we show that negative news events affected Sanders and Clintons subscription trends negatively, while showing no effect for Donald Trump. This gives empirical credence to Trumpâs controversial claim that he could âstand in the middle of 5th Avenue and shoot somebody and not lose any votersâ. We offer a number of explanations for the observed phenomena: the nature of the content of the three subreddits, their cultural dynamics, and changing dynamics of partisanship. We posit that the âdeath of expertiseâ expresses itself on Reddit as a switch in persuasion tactics from a policy-based to an emotions-based approach, and that group membersâ agreement on policy proved a weak marker for online communitiesâ group identity and cohesion. We also claim that strong partisanship coupled with weak party affiliation among Millennials contributed to the low levels of Democratic support consolidation after Clinton won the nomination
Speckle-free laser imaging
Many imaging applications require increasingly bright illumination sources,
motivating the replacement of conventional thermal light sources with light
emitting diodes (LEDs), superluminescent diodes (SLDs) and lasers. Despite
their brightness, lasers and SLDs are poorly suited for full-field imaging
applications because their high spatial coherence leads to coherent artifacts
known as speckle that corrupt image formation. We recently demonstrated that
random lasers can be engineered to provide low spatial coherence. Here, we
exploit the low spatial coherence of specifically-designed random lasers to
perform speckle-free full-field imaging in the setting of significant optical
scattering. We quantitatively demonstrate that images generated with random
laser illumination exhibit higher resolution than images generated with
spatially coherent illumination. By providing intense laser illumination
without the drawback of coherent artifacts, random lasers are well suited for a
host of full-field imaging applications from full-field microscopy to digital
light projector systems.Comment: 5 pages, 4 figure
Molecular dynamics simulations reveal that AEDANS is an inert fluorescent probe for the study of membrane proteins
Computer simulations were carried out of a number of AEDANS-labeled single cysteine mutants of a small reference membrane protein, M13 major coat protein, covering 60% of its primary sequence. M13 major coat protein is a single membrane-spanning, α-helical membrane protein with a relatively large water-exposed region in the N-terminus. In 10-ns molecular dynamics simulations, we analyze the behavior of the AEDANS label and the native tryptophan, which were used as acceptor and donor in previous FRET experiments. The results indicate that AEDANS is a relatively inert environmental probe that can move unhindered through the lipid membrane when attached to a membrane protein
National identity predicts public health support during a global pandemic
Changing collective behaviour and supporting non-pharmaceutical interventions is an important component in mitigating virus transmission during a pandemic. In a large international collaboration (Study 1, N = 49,968 across 67 countries), we investigated self-reported factors associated with public health behaviours (e.g., spatial distancing and stricter hygiene) and endorsed public policy interventions (e.g., closing bars and restaurants) during the early stage of the COVID-19 pandemic (April-May 2020). Respondents who reported identifying more strongly with their nation consistently reported greater engagement in public health behaviours and support for public health policies. Results were similar for representative and non-representative national samples. Study 2 (N = 42 countries) conceptually replicated the central finding using aggregate indices of national identity (obtained using the World Values Survey) and a measure of actual behaviour change during the pandemic (obtained from Google mobility reports). Higher levels of national identification prior to the pandemic predicted lower mobility during the early stage of the pandemic (r = â0.40). We discuss the potential implications of links between national identity, leadership, and public health for managing COVID-19 and future pandemics
