We believe that members of the scientific community have a primary obligation to promote integrity in research and that this obligation includes a duty to report observations that suggest misconduct to agencies that are empowered to examine and evaluate such evidence. Consonant with this responsibility, we became whistleblowers in the case of Herbert Needleman. His 1979 study (Needleman et al., 1979), on the effects of low-level lead exposure on children, is widely cited and highly influential in the formulation of public policy on lead. The opportunity we had to examine subject selection and data analyses from this study was prematurely halted by efforts to prevent disclosure of our observations. Nevertheless, what we saw left us with serious concerns. We hope that the events here summarized will contribute to revisions of process by which allegations of scientific misconduct are handled and that such revisions will result in less damage to scientists who speak out. 相似文献

This study explored whether organizational change had differential effects on perceptions of group leadership and group morale, depending on the source of the change activity. Data on work group leadership and morale was collected in two waves of an employee survey, and data on change activities were collected in the second wave of the survey. When leaders outside of a work group initiated change, employees reported more negative perceptions of their work group leader. However, when the work group leader initiated change, perceptions of that leader tended to be more positive. Finally, change activities initiated by group members did not influence perceptions of work group leadership, but were associated with improved work group morale. 相似文献

This study evaluated the effectiveness of awareness training for the reduction of three nervous habits that manifest during public speaking: filled pauses, tongue clicks, and inappropriate use of the word “like.” Four university students delivered short speeches during baseline and assessment sessions. Awareness training resulted in meaningful reductions in target behaviors for all participants. Booster awareness training sessions were necessary for all participants to achieve further reductions in target behaviors. Generality probes conducted in front of a small audience indicated that treatment effects generally maintained. Social validity scores indicated that the treatment was acceptable, and participants indicated not only decreased use of verbal fillers, but also improved overall public speaking ability posttreatment. 相似文献

We evaluated the psychometric properties of scores on the Need for Affect–Short Form (NAQ–S) in 3 samples: undergraduate students (Sample I), jury-eligible community members (Sample II), and forensic clinicians (Sample III). Concerning factor structure, the NAQ–S 2-factor structure displayed good fit to the data in Sample I, with mostly acceptable levels of internal consistency for both approach and avoidance scores. Construct validity patterns were observed such that approach scores were most strongly correlated with female gender and trait agreeableness scores, whereas avoidance scores were most strongly correlated to trait agreeableness scores. Criterion validity associations emerged in that approach scores displayed main effects on mock juror judgments in hate crimes, and forensic clinician judgments of violence risk estimation. Finally, avoidance scores displayed moderating effects on recommended sentencing length by hate crime victim type. Implications are discussed for emotion in legal decision making and future research. 相似文献

This pilot study examined 186 healthy adults who received a 20-min full-body massage in a robotic massage chair. The majority of the participants rated the experience to be highly pleasurable, and this evaluation was influenced by age and life satisfaction. Large changes in pre- to post-massage symptoms of anxiety and tranquillity were also observed. These preliminary findings support the psychological effectiveness of robotic chair massage which can be readily used by lay people and professionals alike to promote mental health and well-being. 相似文献

Online social networking sites, such as Facebook, have provided a new platform for individuals to produce and reproduce gender through social interactions. New mothers, in particular, may use Facebook to practice behaviors that align with their mothering identity and meet broader societal expectations, or in other words, to “do motherhood.” Given that Facebook use may undermine well-being, it is important to understand the individual differences underlying new mothers’ experiences with Facebook during the stressful first months of parenthood. Using survey data from a sample of 127 new mothers with Facebook accounts residing in the U.S. Midwest, we addressed two key questions: (a) Are individual differences in new mothers’ psychological characteristics associated with their use and experiences of Facebook? and (b) Are new mothers’ psychological characteristics associated with greater risk for depressive symptoms via their use and experiences of Facebook? Regression analyses revealed that mothers who were more concerned with external validation of their identities as mothers and those who believed that society holds them to excessively high standards for parenting engaged in more frequent Facebook activity and also reported stronger emotional reactions to Facebook commentary. Moreover, mothers who were more concerned with external validation were more likely to have featured their child in their Facebook profile picture. Mediation analyses indicated that mothers who were more prone to seeking external validation for their mothering identity and perfectionistic about parenting experienced increases in depressive symptoms indirectly via greater Facebook activity. 相似文献

Whether children should be offered genetic testing for cancer risk is much debated but young voices are rarely heard in these conversations. The current study explored perspectives of genetic testing held by adolescents and emerging adults in families with Li Fraumeni syndrome (LFS). Twelve 12- to 25-year-olds in families with LFS completed qualitative interviews for this study. All believed that testing should be offered for children but many qualified this statement saying parental approval would be needed and testing should be optional. Genetic testing was seen as way to learn of risk status, allow for disease prevention efforts, and reduce uncertainty and anxiety. Perceived disadvantages included negative emotions associated with the testing result. Participants generally felt that children should be involved in the testing decision, but that parents could unilaterally decide to have a child tested in certain circumstances (e.g., young age, high risk). All who were aware of having been tested and of their test result (n = 7; 4 positive) said testing had no negative impact on their outlook and they agreed with the decision to undergo testing. Implications of these findings for clinical practice and future research are discussed. 相似文献

Research on bullying has grown very rapidly in the last two decades, initially in schools but also in a variety of other settings and relationships; and there has been relatively little communication between the different groups of researchers. We describe the nature of bullying in schools, between siblings, in children's residential care homes, in prisons, and in the workplace. Commonalities and differences in the phenomenon, and the ways in which it is exhibited and experienced are explored. The role of individual and organizational factors in the development and maintenance of these behaviors across contexts is compared. We then examine a number of theoretical approaches which have been suggested as relevant to our understanding of bullying. Integrative approaches from different research traditions are proposed which view these behaviors as being influenced by a combination of situational and individual factors. 相似文献

Episodic memory is compromised in amnestic mild cognitive impairment (aMCI), but lesser deficits in other cognitive domains are also commonly observed and may be helpful in identifying this group. The relative difference in performance on lexical and semantic fluency tasks may be a sensitive and specific measure in aMCI and early Alzheimer's disease (AD). We compared four groups of participants, 35 early AD, 47 aMCI, 24 healthy controls, and 18 depressive out‐patient controls, on semantic and lexical fluency as well as other neuropsychological tests. Early AD and aMCI patients showed a distinct pattern of semantic impairment in the two fluency measures compared with the healthy and depressive controls. The findings implicate early failure of the semantic memory system in aMCI and AD and suggest that consideration of the discrepancy in performance on semantic and lexical fluency measures may help in the early identification of AD. 相似文献

The aim of this study was to explore in detail the psychosocial impact of either having familial adenomatous polyposis (FAP)
or being at risk for FAP amongst young adults. In-depth interviews were conducted with eleven individuals aged 18–35 with
a clinical or genetic diagnosis of, or at risk of developing FAP. While being at risk did not seem to have a major psychosocial
impact upon clinically unaffected participants, clinically affected individuals discussed a number of major stressors including
issues in relation to changes in body image and physical functioning as a result of surgery, concerns about discussing FAP
with new partners, difficulties in relation to childbearing decision-making, and impact on employment. Genetic counseling
was described as being highly effective in providing support, but most participants were not aware of any other support services.
Providing longer-term support through ongoing genetic counseling appears necessary to adequately address the ongoing challenges
faced by young adults who are dealing with FAP. 相似文献
