Teachers' Perceptions of Bullying of Lesbian, Gay, Bisexual, Transgender, and Questioning (LGBTQ) Students in a Southwestern Pennsylvania Sample.

This study was designed to ascertain teachers' perceptions of bullying of Lesbian, Gay, Bisexual, Transgender, and Questioning (LGBTQ) youth. In a sample of 200 educators (61.0% female; 96.

Warning signal brightness variation: sexual selection may work under the radar of natural selection in populations of a polytypic poison frog.

Though theory predicts consistency of warning signals in aposematic species to facilitate predator learning, variation in these signals often occurs in nature. The strawberry poison frog Dendrobates pumilio is an exceptionally polytypic (populations are phenotypically distinct) aposematic frog exhibiting variation in warning color and brightness. In the Solarte population, males and females both respond differentially to male brightness variation.

Maltreatment and depression in adolescent sexual offenders with an autism spectrum disorder.

This study examined the self-reported presence and severity of abuse, neglect, and depressive symptoms for 43 adolescents adjudicated delinquent due to a sexual offense. Twenty-seven of the adolescent sexual offenders were also diagnosed with an autism spectrum disorder, and 16 did not carry an autism spectrum disorder diagnosis. Both groups reported moderate to high levels of abuse and neglect.

Callous and unemotional traits and social cognitive processes in a sample of community-based aggressive youth.

Psychopathic traits are associated with violent, aggressive behaviors and recidivism in adulthood. To increase positive treatment outcomes, it is arguably beneficial to identify and treat psychopathy as early as possible. Furthermore, because research shows that the effectiveness of behavior modification is likely to be affected by the social information-processing patterns of aggressive children, it is important to understand the relationship between conduct-disordered traits and social cognitions.

Aposematic signal variation predicts male-male interactions in a polymorphic poison frog.

Many species use conspicuous "aposematic" signals to communicate unpalatability/unprofitability to potential predators. Although aposematic traits are generally considered to be classic examples of evolution by natural selection, they can also function in the context of sexual selection, and therefore comprise exceptional systems for understanding how conspicuous signals evolve under multifarious selection. We used males from a highly territorial poison frog species in a dichotomous choice behavioral test to conduct the first examination of how aposematic signal variation influences male-male interactions.

Epidemiological study of E. coli O157:H7 isolated in Northern Ireland using pulsed-field gel electrophoresis (PFGE).

In Northern Ireland over the last 7 years, there is a mean of 41.9 laboratory reports per annum of human gastrointestinal infection (range 19-54) caused by Escherichia coli O157:H7. In the preceding years 1992-1996, reports were 5.

A clinical comparison of lesbian and heterosexual women in a psychiatric outpatient clinic.

Previous research has reported that when compared to heterosexual women, lesbians may use alcohol and illicit substances to a greater degree and may experience greater psychiatric symptomatology. This study sought to describe any differences in clinical diagnoses, familial histories, and substance usage between lesbian and heterosexual women in a psychiatric outpatient clinic. A chart review was conducted and a sample of 455 heterosexuals and 75 lesbians was obtained.

Early intervention with difficult to engage, 'high-risk' youth: evaluating an intensive outreach approach in youth mental health.

Background: Although intensive outreach (IO) models such as assertive community treatment and intensive case management have a strong evidence base in adult psychiatry, their effectiveness in the early intervention sector is unknown.

Aim: To explore client characteristics and treatment effects in a group of difficult to engage, 'high-risk' young people, seen by the Intensive Mobile Youth Outreach Service (IMYOS, ORYGEN Youth Heath) in Western Metropolitan Melbourne.

Methods: The clinical files of 47 clients were audited, targeting demographic and treatment outcome data prior to and during IMYOS involvement.

Effects of time-limited dynamic psychotherapy on distress among HIV-seropositive men who have sex with men.

The current study seeks to examine changes in distress associated with receiving time-limited dynamic psychotherapy (TLDP) among men who have sex with men (MSM) who are also living with HIV and AIDS. Participants included 79 HIV-seropositive MSM who were seeking psychotherapy at a community mental health clinic between January 2000 and June 2005. Participants' had a mean age of 42 and were predominantly European American (77%), although Latinos (13%), African Americans (5%), and Asian Americans (4%) were also included.

The damage done: a study of injection drug use, injection related abscesses and needle exchange regulation.

This study investigated the impact of a needle exchange policy change on community health. Data were collected from a needle exchange program in Eureka, California, for clients who participated in the program between the weeks (n = 112) of January 1, 2002, and February 28, 2004. Analysis was done using an autoregressive integrated moving average (ARIMA), indicating that greater utilization of the needle exchange program, in terms of needles exchanged and number of visits, is related to fewer numbers of abscesses treated.

Molecular genotyping of human cryptosporidiosis in Northern Ireland: epidemiological aspects and review.

Background: Cryptosporidium parvum is the most common of the protozoal pathogens associated with gastrointestinal disease in Northern Ireland. Genotyping techniques are valuable in helping to elucidate sources and modes of transmission of this parasite. There have been no reports on the prevalence of genotypes in Northern Ireland, mainly due to a lack of discriminatory genotyping techniques, which recently have become available.

The dilemma of factitious demographic distinctions in psychological research.

Terms such as race, sex and age are assumed to reflect biological characteristics and distinctions. In psychological research, these terms are often treated as if they were a reflection of a meaningful set of psychological constructs. A review of articles in 3 prominent journals over a 30-year period reveals that these supposed biological identifiers are not used consistently and lack empirical and conceptual validity.
