A complex array of intersecting social contextual factors are known to influence safer and/or unsafe practices among people who inject drugs. However, less is known about the social contextual factors that may specifically influence injection practices for young people who inject drugs. In this qualitative study, we explored with young people, ages 18-29, living in an urban centre in Nova Scotia, Canada, their perceptions and experiences of the social contextual factors that influence their safer and/or unsafe injection practices...

Food safety is a fundamental concern for both consumers and the food industry, especially as the numbers of reported cases of food-associated infections continue to increase. Industrial surfaces can provide a suitable substrate for the development and persistence of bacterial organized in biofilms that represent a potential source of food contamination. The negative consumer perception of chemical disinfectants has shifted the attention to natural substances, such as plant extracts. The aim of this study was to investigate the possibility of using the essential oils (EOs) in the fight against S...

Rotavirus (RV) is the most common cause of severe gastroenteritis in infants and young children worldwide. RV causes approximately half a million deaths each year among children aged <5 years. According to WHO estimates for 2008, there were approximately 10 to 50 deaths annually in young children due to rotavirus diarrhea in Georgia. The purpose of this study was to assess the knowledge, attitudes, and practices related to rotavirus diarrhea and the rotavirus vaccine among health care workers (HCWs). The National Center for Disease Control and Public Health (NCDC) conducted a cross-sectional survey of HCWs involved in the expanded program of immunization (EPI)...

Local adaptation can be a potent force in speciation, with environmental heterogeneity leading to niche specialization and population divergence. However, local adaption often requires non-random mating in order to generate reproductive isolation. Population divergence in sensory properties can be particularly consequential in speciation, affecting both ecological adaptation and sexual communication. Pundamilia pundamila and Pundamilia nyererei are two closely related African cichlid species that differ in male coloration, blue vs...

Surprisingly little is known about how the brain combines spatial elements to form a coherent percept. Regions that may underlie this process include the hippocampus (HC) and parahippocampal place area (PPA), regions central to spatial perception but whose role in spatial coherency has not been explored. Participants were scanned with functional MRI while they judged whether Escher-like scenes were possible or impossible. Univariate analyses revealed differential HC and PPA involvement, with greater HC activity during spatial incoherency detection and more PPA activity during spatial coherency detection...

The laterosensory system is a mechanosensory modality involved in many aspects of fish biology and behavior. Laterosensory perception may be crucial for individual survival, especially in habitats where other sensory modalities are generally useless, such as the permanently aphotic subterranean environment. In the present study, we describe the laterosensory canal system of epigean and subterranean species of the genus Ituglanis (Siluriformes: Trichomycteridae). With seven independent colonizations of the subterranean environment in a limited geographical range coupled with a high diversity of epigean forms, the genus is an excellent model for the study of morphological specialization to hypogean life...

Perspectives on the status of human embryos and whether they should be discarded differ globally. Some countries protect embryos in law while in other countries embryos 'die' or 'succumb' in assisted reproductive technology clinics on a daily basis. This study analyses interview data drawn from a larger qualitative study conducted in South Australia from 2004-2007. 21 women and 12 of 21 partners were interviewed about the decision they made to discard their embryos. The analysis reported here sought to examine the ways in which women constructed and experienced the decision to discard embryos...

Nutrition is an essential component in promoting health and quality of life into the older adults years. The purpose of this qualitative research is to explore how the rural food environment influences food choices of older adults. Four focus groups were conducted with 33 older adults (50 years of age and older) residing in rural Montana communities. Four major themes related to factors influencing food choices among rural older adults emerged from this study: perception of the rural community environment, support as a means of increasing food access, personal access to food sources, and dietary factors...

Schizophrenia is associated with significant impairments in social cognition. These impairments have been shown to go along with altered activation of the posterior superior temporal sulcus (pSTS). However, studies that investigate connectivity of pSTS during social cognition in schizophrenia are sparse. Twenty-two patients with schizophrenia and 22 matched healthy controls completed a social-cognitive task for functional magnetic resonance imaging that allows the investigation of affective Theory of Mind (ToM), emotion recognition and the processing of neutral facial expressions...

Neural discrimination of auditory intensity is one of the fundamental questions in human auditory perception. Human neuroimaging studies have demonstrated specific neural activations during intensity discrimination tasks. The detailed functional anatomy, however, remains elusive. Most of the existing studies examined the entire auditory cortex as a whole, neglecting the potential functional differentiation within the auditory cortex. Moreover, these previous results based on controlled auditory stimuli might not necessarily extend to the neural mechanism of natural auditory processing...

According to Bayesian models, perception and cognition depend on the optimal combination of noisy incoming evidence with prior knowledge of the world. Individual differences in perception should therefore be jointly determined by a person's sensitivity to incoming evidence and his or her prior expectations. It has been proposed that individuals with autism have flatter prior distributions than do nonautistic individuals, which suggests that prior variance is linked to the degree of autistic traits in the general population...

Research shows that child sexual abuse (CSA) can have detrimental effects on adult functioning. While much research regarding the effects of CSA on parenting of mothers is available, there is a dearth of information on how CSA impacts fatherhood. This literature review finds that the parenting experiences of male survivors are characterized by self-perceptions as adequate parents, deficient parenting as measured by standardized instruments, conceptualization of parenting as an intergenerational legacy and potential healing experience, fear of becoming an abuser, and physical and emotional distance from their children...

Fidelity of implementation is an essential factor in realizing outcomes of evidence-based interventions. Yet perspectives vary on the degree to which fidelity is necessary or desirable, implementers may receive limited guidance on fidelity, and research on implementers' understanding and operationalization of fidelity is lacking. We conducted key informant interviews with 20 individuals who implemented an evidence-based teen dating violence prevention curriculum in seven sites. Interviews addressed how implementers defined fidelity and the adaptations they made in implementing the curriculum...
