University psychology and sociology researchers rated the likelihood they would engage in misconduct as described in 9 research scenarios, while also making moral judgments and rating the likelihood of discovery and sanctions. Multiple regression revealed significant effects across various scenarios for moral judgment as well as shame and embarrassment on reducing misconduct. The effects on misconduct of the perceived probability of sanctions were conditioned on moral judgments in some scenarios. The results have implications for how universities address the prevention, detection, and sanctioning of research misconduct.  相似文献

Genetic counseling and testing for hereditary breast cancer have the potential benefit of early detection and early interventions in African American women. However, African American women have low use of these services compared to White women. We conducted two focus groups with African American women diagnosed with breast cancer (affected group, n?=?13) and women with at least one first-degree relative with breast/ovarian cancer (unaffected group, n?=?8). A content analysis approach was employed to analyze interview data. Breast cancer survivors had more knowledge about genetic counseling and testing than participants who were unaffected with cancer. However, knowledge about genetic counseling was limited in both groups. Barriers to pursuing genetic counseling and testing included poor understanding of the genetic counseling and testing process, fear of carrying the mutation, concerns about discrimination, and cost. Motivators to participate in genetic counseling and testing included desire to help family members, insurance coverage, and potential of benefiting the larger African American community. Education efforts are needed to increase genetic counseling and testing awareness in the African American community.  相似文献

Whole genome sequencing (WGS) is being used for evaluation of individuals with undiagnosed disease of suspected genetic origin. Implementing WGS into clinical practice will place an increased burden upon care teams with regard to pre-test patient education and counseling about results. To quantitate the time needed for appropriate pre-test evaluation of participants in WGS testing, we documented the time spent by our clinical research group on various activities related to program preparation, participant screening, and consent prior to WGS. Participants were children or young adults with autism, intellectual or developmental disability, and/or congenital anomalies, who have remained undiagnosed despite previous evaluation, and their biologic parents. Results showed that significant time was spent in securing allocation of clinical research space to counsel participants and families, and in acquisition and review of participant’s medical records. Pre-enrollment chart review identified two individuals with existing diagnoses resulting in savings of $30,000 for the genome sequencing alone, as well as saving hours of personnel time for genome interpretation and communication of WGS results. New WGS programs should plan for costs associated with additional pre-test administrative planning and patient evaluation time that will be required to provide high quality care.  相似文献

Evidence of distributional learning, a statistical learning mechanism centered on relative frequency of exposure to different tokens, has mainly come from short-term learning and therefore does not ostensibly address the development of important learning processes. The present longitudinal study examines both short- and long-term effects of distributional learning of phonetic categories on non-native sound discrimination over a 12-month period. Two groups of listeners were exposed to a two-minute distribution of auditory stimuli in which the most frequently presented tokens either approximated or exaggerated the natural production of the speech sounds, whereas a control group listened to a piece of classical music for the same length of time. Discrimination by listeners in the two distribution groups improved immediately after the short exposure, replicating previous results. Crucially, this improvement was maintained after six and 12 months, demonstrating that distributional learning has long-lasting effects.  相似文献

This pilot study compares an emerging evidence-based treatment, holographic reprocessing (HR) to prolonged exposure (PE) versus a person-centered (PC) control group to treat symptoms of distress in female Veterans with sexual trauma. In contrast to PE, HR does not include exposure to a target event of trauma. Instead, HR focuses on healing the internal working model or type of attachment style that may form as a result of interpersonal trauma or maltreatment. The model reveals how people perceive themselves and others. These perceptions set in motion emotional, cognitive, and behavioral tendencies wherein people unconsciously replicate similar types of relationships that reinforce their worldview. Fifty-one female Veterans with sexual trauma were randomly assigned to one of three treatments and completed pre- and post-treatment measures of psychiatric symptoms (anxiety, depression, and PTSD) and post-traumatic cognitions. ANOVAs found significant decreases on all variables. Post-hoc comparisons revealed that HR and PE treatments demonstrated significantly greater decreases in symptoms compared to the PC control group. Chi square analyses revealed that HR produced a significantly lower dropout rate 1 (6 %) compared to PE 7 (41 %) and PC 6 (35 %). These initial results are promising and further investigation of HR is warranted.  相似文献
