The power of friends in reducing sexual assault risk in college women: A preliminary test of dyad-based motivational intervention approach.

Objective: Sexual assault (SA) is unfortunately common in U.S. college campuses.

The Cyborg Method: A Method to Identify Fraudulent Responses from Crowdsourced Data.

Crowdsourcing is an essential data collection method for psychological research. Concerns about the validity and quality of crowdsourced data persist, however. A recent documented increase in the number of invalid responses within crowdsourced data has highlighted the need for quality control measures.

Protein Corona Formation and Aggregation of Amyloid β 1-40-Coated Gold Nanocolloids.

Amyloid fibrillogenesis is a pathogenic protein aggregation process that occurs through a highly ordered process of protein-protein interactions. To better understand the protein-protein interactions involved in amyloid fibril formation, we formed nanogold colloid aggregates by stepwise additions of ∼2 nmol of amyloid β 1-40 peptide (Aβ) at pH ∼3.7 and ∼25 °C.

An approach for in-situ detection of gold colloid aggregates amyloid formations within the hippocampus of the Cohen's Alzheimer's disease rat model by surface enhanced raman scattering methods.

Background: Amyloid beta (Aβ) peptides, such as Aβ or Aβ are regarded as hallmark neuropathological biomarkers associated with Alzheimer's disease (AD). The formation of an aggregates by Aβ or Aβ-coated gold nano-particles are hypothesized to contain conformation of Aβ oligomers, which could exist only at an initial stage of fibrillogenesis.

New Method: The attempt of in-situ detection of externally initiated gold colloid (ca.

Bidirectional effects between maternal mental health and adolescent internalizing problems across six years in Northern Ireland.

Background: Emerging evidence indicates the existence of bidirectional relations between mothers' mental health and adolescent adjustment, but few studies have examined these relations in contexts of high environmental adversity, including economic deprivation and political violence. Given other empirical connections between political violence and adolescent adjustment problems, the impact of child adjustment problems on maternal mental health may be exacerbated in contexts of sectarian violence.

Methods: Addressing this gap, latent change score modeling was used to examine interrelations between trajectories of maternal mental health and adolescent internalizing symptoms over time in communities afflicted by political conflict.

Nano-size dependent protein corona formation by SARS-CoV-2 Omicron spike protein over gold nano-colloid and reversible aggregation.

The adsorption process of SARS-CoV-2 Omicron spike protein to the nano-gold colloid surfaces was examined by monitoring the surface plasmon resonance (SPR) band shift of gold-nano particles ranging between diameters of d = 10-100 nm. The externally changed pH between 3 and 11 at 24.5 ± 0.

Nano-size dependence in the adsorption by the SARS-CoV-2 spike protein over gold colloid.

Gold nano-particles were coated with the spike protein (S protein) of SARS-CoV-2 and exposed to increasingly acidic conditions. Their responses were investigated by monitoring the surface plasmon resonance (SPR) band shift. As the external pH was gradually changed from neutral pH to pH ∼2 the peak of the SPR band showed a significant red-shift, with a sigmoidal feature implying the formation of the gold-protein aggregates.

Spectroscopic investigation on the affinity of SARS-CoV-2 spike protein to gold nano-particles.

The affinity of the SARS-CoV-2 spike protein (S protein) to gold nano-particles was examined through spectral shifts of SPR (Surface Plasmon Resonance) band. Gold nano-colloidal particles are sensitive to the conformational change of the protein adsorbed over the particles' surface. As the pH value was gradually lowered from approximately neutral pH to an acidic pH ( pH 2), all mixtures of S protein with the gold colloids ≥30 nm in diameter exhibited a drastic red-shift of the average SPR band peak at one pH value more than that observed for bare gold colloids.

Youth in Northern Ireland: Linking Violence Exposure, Emotional Insecurity, and the Political Macrosystem.

Growing up in the aftermath of armed conflict puts youth at a higher risk for psychopathology-particularly in societies like Northern Ireland which continue to be characterized by intergroup tension and cyclical violence. This risk may be heightened during adolescence, when youth are beginning to explore their identities and are becoming more aware of intergroup dynamics in both their immediate communities and the broader society. It is also during this stage when youth increasingly witness or engage in antisocial behavior and sectarian activities.

Relations Among Father's Presence, Family Conflict, and Adolescent Adjustment in Northern Ireland.

Burgeoning evidence identifies the influence of fathers and, relatedly, fathers in the family context (e.g., family conflict), on adolescent adjustment.

Parental competitive victimhood and interethnic discrimination among their children: The mediating role of ethnic socialization and symbolic threat to the in-group.

Links between competitive victimhood and discrimination are well documented. However, the mechanisms how victimhood beliefs remain relevant for decades and how conflict survivors can shape attitudes and behaviours of the post-conflict generations are little understood. Following the Transgenerational Transmission Hypothesis and the Integrated Threat Theory, we propose that the link between parental competitive victimhood and discrimination among their children is mediated through family ethnic socialization and symbolic threat to the in-group.

Individual and Institutional Predictors of IPV/SV Screening in College Health Centers.

Intimate partner violence (IPV) and sexual violence (SV) are significant public health issues for women, particularly for college women. IPV and SV have been associated with numerous adverse health consequences and involvement in unhealthy behaviors. Given the health risks and high rates of IPV/SV among college women, it is important to understand and promote screening in this population.

The Entertainment-Education Strategy in Sexual Assault Prevention: A Comparison of Theoretical Foundations and a Test of Effectiveness in a College Campus Setting.

Among the existing sexual assault prevention efforts on college campuses, few use mass communication strategies designed to simultaneously entertain and educate. Although many entertainment-education efforts are guided by social cognitive theory, other theories may be useful in entertainment-education design. Previous research has found that social cognitive theory and social norms theory can successfully influence participants' perceived norms and efficacy related to sexual assault reduction; however, whether such results can be replicated in a naturalistic setting and the extent to which the guiding theoretical foundation may influence outcomes remain unknown.

The Nurse Who Saw Me.

A mother's long night at her sick newborn's side. What can possibly ease the strain?

Assessing the accuracy of subject-specific, muscle-model parameters determined by optimizing to match isometric strength.

Biomechanical models are sensitive to the choice of model parameters. Therefore, determination of accurate subject specific model parameters is important. One approach to generate these parameters is to optimize the values such that the model output will match experimentally measured strength curves.

A multilevel prediction of physiological response to challenge: Interactions among child maltreatment, neighborhood crime, endothelial nitric oxide synthase gene (eNOS), and GABA(A) receptor subunit alpha-6 gene (GABRA6).

Physiological response to stress has been linked to a variety of healthy and pathological conditions. The current study conducted a multilevel examination of interactions among environmental toxins (i.e.

Dietary carbohydrate restriction as the first approach in diabetes management: critical review and evidence base.

The inability of current recommendations to control the epidemic of diabetes, the specific failure of the prevailing low-fat diets to improve obesity, cardiovascular risk, or general health and the persistent reports of some serious side effects of commonly prescribed diabetic medications, in combination with the continued success of low-carbohydrate diets in the treatment of diabetes and metabolic syndrome without significant side effects, point to the need for a reappraisal of dietary guidelines. The benefits of carbohydrate restriction in diabetes are immediate and well documented. Concerns about the efficacy and safety are long term and conjectural rather than data driven.

Violent media consumption and the recognition of dynamic facial expressions.

This study assessed the speed of recognition of facial emotional expressions (happy and angry) as a function of violent media consumption. Color photos of calm facial expressions morphed to either an angry or a happy facial expression. Participants were asked to make a speeded identification of the emotion (happiness or anger) during the morph.

Violent comic books and judgments of relational aggression.

This study investigated the effects of reading extremely violent versus mildly violent comic books on the interpretation of relational provocation situations. One hundred and seventeen introductory psychology students read either an extremely violent comic book or a mildly violent comic book. After reading the comic books, participants read five hypothetical stories in which a child, caused a relationally aggressive event to occur to another child, but the intent of the provocateur was ambiguous.

Attitudes and beliefs about childbirth among college students: results of an educational intervention.

Background: Research on knowledge of childbirth has focused primarily on expectant mothers. The purpose of this study was to investigate college student beliefs, knowledge of, and interest in learning more about childbirth.

Methods: Qualitative research methods were used to analyze college students' written responses to a childbirth video as the first stage in a research project aimed at understanding nulliparous and prepaternity knowledge of childbirth among adolescents and young adults.

Criterion validity of the Language Background Questionnaire: a self-assessment instrument.

The present investigation examined relationships between the Language Background Questionnaire (LBQ) self-assessed sign language skills. LBQ self-assessed spoken communication skills, and formal independent sign and spoken communication skills assessments of young adults who are deaf or hard of hearing. Results indicated a high degree of congruence between self-assessed communication skills and formal independent assessments of communication skills.

Voice onset time in speech produced during simultaneous communication.

This study investigated speaking rate and voice onset time (VOT) in speech produced during simultaneous communication (SC) by speakers with normal hearing. Stimulus words initiated with voiced and voiceless plosives were embedded in a sentence that was spoken and produced with SC. VOT measures were calculated from acoustic recordings and results indicated significant differences between speech-only and SC conditions, with speech produced during SC demonstrating both slower speaking rate and increased VOT of voiceless consonants.
