Cognitive bias and severity of harm following surgery: Plan for workflow debiasing strategy.

Introduction: This study analyzes the relationship between cognitive bias (CB) and harm severity as measured by Clavien-Dindo Scores (CD).

Methods: A prospectively collected series of 655 severity matched general surgical cases with complications were analyzed. Cases were evaluated for CB and assigned harm scores as defined by CD grade.

Detection and Quantitation of Trace Fentanyl in Heroin by Surface-Enhanced Raman Spectroscopy.

The identification of fentanyl, a main culprit in opioid overdose deaths, has become critical. Whereas Raman spectroscopy is an effective tool for detecting illicit drugs, the weak intensity of Raman scattering can make it difficult to distinguish trace materials. This shortcoming is addressed by surface-enhanced Raman spectroscopy (SERS), which produces strong signal enhancements when target compounds are near metal nanoparticles.

'It's just an excuse to slut around': gay and bisexual mens' constructions of HIV pre-exposure prophylaxis (PrEP) as a social problem.

Since the 2012 FDA approval of HIV Pre-exposure Prophylaxis (PrEP) as a method to prevent HIV, its uptake among gay and bisexual men has been met with conflict. Drawing on discussions of PrEP from focus groups with gay and bisexual men in New York City (N = 5 groups, n = 32 participants), we sought to make meaning of the moral debate surrounding the implementation of biomedical HIV prevention medications. Grounded in the constructionist perspective on social problems, this case study focuses on the competing claims making activities gay and bisexual men engage in when framing PrEP and PrEP users.

"I Was Not Sick and I Didn't Need to Recover": Methadone Maintenance Treatment (MMT) as a Refuge from Criminalization.

Background: Methadone Maintenance Treatment (MMT) in the United States (U.S.) has been undergoing a shift towards conceptualizing the program as recovery-based treatment.

Second-language learning effects on automaticity of speech processing of Japanese phonetic contrasts: An MEG study.

We examined discrimination of a second-language (L2) vowel duration contrast in English learners of Japanese (JP) with different amounts of experience using the magnetoencephalography mismatch field (MMF) component. Twelve L2 learners were tested before and after a second semester of college-level JP; half attended a regular rate course and half an accelerated course with more hours per week. Results showed no significant change in MMF for either the regular or accelerated learning group from beginning to end of the course.

Neural measures of a Japanese consonant length discrimination by Japanese and American English listeners: Effects of attention.

This study examined automaticity of discrimination of a Japanese length contrast for consonants (miʃi vs. miʃʃi) in native (Japanese) and non-native (American-English) listeners using behavioral measures and the event-related potential (ERP) mismatch negativity (MMN). Attention to the auditory input was manipulated either away from the auditory input via a visual oddball task (Visual Attend), or to the input by asking the listeners to count auditory deviants (Auditory Attend).

The effect of native-language experience on the sensory-obligatory components, the P1-N1-P2 and the T-complex.

The influence of native-language experience on sensory-obligatory auditory-evoked potentials (AEPs) was investigated in native-English and native-Polish listeners. AEPs were recorded to the first word in nonsense word pairs, while participants performed a syllable identification task to the second word in the pairs. Nonsense words contained phoneme sequence onsets (i.

Children on the autism spectrum: grandmother involvement and family functioning.

Background: This study investigated associations between the presence of a child with autism or Asperger's disorder in the family, family functioning and grandmother experiences with the goal of better understanding grandparent involvement in the lives of grandchildren on the autism spectrum and their families.

Methods: Mothers and grandmothers of children who were either typically developing or on the autism spectrum completed parallel forms of a grandparent involvement measure. Mothers reported on the functioning of the immediate family.

The phonotactic influence on the perception of a consonant cluster /pt/ by native English and native Polish listeners: a behavioral and event related potential (ERP) study.

The effect of exposure to the contextual features of the /pt/ cluster was investigated in native-English and native-Polish listeners using behavioral and event-related potential (ERP) methodology. Both groups experience the /pt/ cluster in their languages, but only the Polish group experiences the cluster in the context of word onset examined in the current experiment. The /st/ cluster was used as an experimental control.

Cross-language perceptual similarity predicts categorial discrimination of American vowels by naïve Japanese listeners.

Current speech perception models propose that relative perceptual difficulties with non-native segmental contrasts can be predicted from cross-language phonetic similarities. Japanese (J) listeners performed a categorical discrimination task in which nine contrasts (six adjacent height pairs, three front/back pairs) involving eight American (AE) vowels [iː, ɪ, ε, æː, ɑː, ʌ, ʊ, uː] in /hVbə/ disyllables were tested. The listeners also completed a perceptual assimilation task (categorization as J vowels with category goodness ratings).

Internalized Homophobia and Relationship Quality among Lesbians, Gay Men, and Bisexuals.

We examined the associations between internalized homophobia, outness, community connectedness, depressive symptoms, and relationship quality among a diverse community sample of 396 lesbian, gay, and bisexual (LGB) individuals. Structural equation models showed that internalized homophobia was associated with greater relationship problems both generally and among coupled participants independent of outness and community connectedness. Depressive symptoms mediated the association between internalized homophobia and relationship problems.

Cross-language categorization of French and German vowels by naive American listeners.

American English (AE) speakers' perceptual assimilation of 14 North German (NG) and 9 Parisian French (PF) vowels was examined in two studies using citation-form disyllables (study 1) and sentences with vowels surrounded by labial and alveolar consonants in multisyllabic nonsense words (study 2). Listeners categorized multiple tokens of each NG and PF vowel as most similar to selected AE vowels and rated their category "goodness" on a nine-point Likert scale. Front, rounded vowels were assimilated primarily to back AE vowels, despite their acoustic similarity to front AE vowels.

Acoustic and perceptual similarity of Japanese and American English vowels.

Acoustic and perceptual similarities between Japanese and American English (AE) vowels were investigated in two studies. In study 1, a series of discriminant analyses were performed to determine acoustic similarities between Japanese and AE vowels, each spoken by four native male speakers using F1, F2, and vocalic duration as input parameters. In study 2, the Japanese vowels were presented to native AE listeners in a perceptual assimilation task, in which the listeners categorized each Japanese vowel token as most similar to an AE category and rated its goodness as an exemplar of the chosen AE category.

Understanding why gay men seek HIV-seroconcordant partners: intimacy and risk reduction motivations.

Our goal was to situate the interest of some gay men in having HIV-seroconcordant partners within the psychosocial context of concurrent motivations for intimacy and sexual risk reduction. Data were obtained from semi-structured qualitative interviews with a racially/ethnically diverse sample of 32 gay men (16 HIV-positive and 16 HIV-negative) living in New York City who sought HIV-seroconcordant partners. Thematic analysis indicated that seroconcordant partner selection was strongly motivated by a desire to reduce sexual risk as well as the pursuit of multiple forms of intimacy.

Identification of environmental sounds with varying spectral resolution.

Objectives: This study investigated the identification of familiar environmental sounds with varying spectral resolution to establish (1) the number of frequency channels needed to perceive a large heterogeneous set of familiar environmental sounds, (2) the role of cross-channel asynchrony in identification performance, and (3) the acoustic correlates of the spectral resolution required for identification.

Design: In experiment 1, 60 normal-hearing listeners identified environmental sounds in a 60-alternative closed--set response task as a function of six spectral resolution conditions (i.e.

On the classification, evolution and biogeography of terrestrial haemadipsoid leeches (Hirudinida: Arhynchobdellida: Hirudiniformes).

A scourge of tropical and subtropical jungles, bloodfeeding terrestrial leeches of Haemadipsidae have long confused systematists and defied sensible biogeographic interpretation. The family Haemadipsidae usually includes problematic taxa that neither fit the typical IndoPacific distribution of the group, nor properly match diagnostic characters used to define the family. Historically, four additional families-Xerobdellidae, Diestecostomatidae Mesobdellidae and Nesophilaemonidae-have occasionally been recognized for New World and European representatives, though agreement on the composition of those families has not been consistent.

Acoustic and perceptual similarity of North German and American English vowels.

Current theories of cross-language speech perception claim that patterns of perceptual assimilation of non-native segments to native categories predict relative difficulties in learning to perceive (and produce) non-native phones. Cross-language spectral similarity of North German (NG) and American English (AE) vowels produced in isolated hVC(a) (di)syllables (study 1) and in hVC syllables embedded in a short sentence (study 2) was determined by discriminant analyses, to examine the extent to which acoustic similarity was predictive of perceptual similarity patterns. The perceptual assimilation of NG vowels to native AE vowel categories by AE listeners with no German language experience was then assessed directly.

Effects of consonantal context on perceptual assimilation of American English vowels by Japanese listeners.

This study investigated the extent to which adult Japanese listeners' perceived phonetic similarity of American English (AE) and Japanese (J) vowels varied with consonantal context. Four AE speakers produced multiple instances of the 11 AE vowels in six syllabic contexts /b-b, b-p, d-d, d-t, g-g, g-k/ embedded in a short carrier sentence. Twenty-four native speakers of Japanese were asked to categorize each vowel utterance as most similar to one of 18 Japanese categories [five one-mora vowels, five two-mora vowels, plus/ei, ou/ and one-mora and two-mora vowels in palatalized consonant CV syllables, C(j)a(a), C(j)u(u), C(j)o(o)].
