We are reporting what we believe to be the first published case of patient initiated direct to consumer (DTC) genetic testing to test for the presence of a known familial mutation. Our client in this case is from a known MSH2 family; both his/her parent and associated grandparent have previously tested positive for the known familial MSH2 mutation. Using 23andme’s “family inheritance genome-wide comparison” option we were able to determine that our client most likely inherited the known familial MSH2 mutation without pursuing single site genetic testing. Our client pursued DTC genetic testing instead of single site genetic testing due to the fear of genetic discrimination. This case shows that patients are still fearful of genetic discrimination, despite the passage of the Genetic Information Nondiscrimination Act (GINA), and that DTC genetic testing may be useful despite the overall negative feeling towards this type of testing in the genetic counseling community.  相似文献

Humans frequently interact with strangers absent prior direct experience with their behavior. Some conjecture that this may have favored evolution of a cognitive system within the hominoid clade or perhaps the primate order to assign reputations based on third-party exchanges. However, non-primate species’ acquisition of skills from experienced individuals, attention to communicative cues, and propensity to infer social rules suggests reputation inference may be more widespread. We utilized dogs’ sensitivity to humans’ social and communicative cues to explore whether dogs evidenced reputation-like inference for strangers through third-party interactions. Results indicated dogs spontaneously show reputation-like inference for strangers from indirect exchanges. Further manipulations revealed that dogs continued to evidence this ability despite reduction of specific components of the observed interactions, including reduction of visual social cues (i.e., face-to-face contact between the participants in the interaction) and the nature of the recipient (i.e., living, animate agent versus living, inanimate self-propelled agent). Dogs also continued to demonstrate reputation-like inference when local enhancement was controlled and in a begging paradigm. However, dogs did not evidence reputation-like inference when the observed interaction was inadvertent.  相似文献

Creative self-efficacy development and creative performance over time   总被引:2,自引:0,他引:2  
Building from an established framework of self-efficacy development, this study provides a longitudinal examination of the development of creative self-efficacy in an ongoing work context. Results show that increases in employee creative role identity and perceived creative expectation from supervisors over a 6-month time period were associated with enhanced sense of employee capacity for creative work. Contrary to what was expected, employees who experienced increased requirements for creativity in their jobs actually reported a decreased sense of efficaciousness for creative work. Results show that increases in creative self-efficacy corresponded with increases in creative performance as well.  相似文献

Retrospective reports of exposure to physical abuse by an adult during childhood was assessed in 874 adolescents (426 boys, 448 girls; M age = 11.5 yr., SD = 0.8) who also reported whether they had been victimized by school bullying. Having been hit by an adult was significantly more common among victims of school bullying (39.5%) than among adolescents not victimized by school bullying (16.8%). No sex difference was found. The finding raises questions about whether victimization by physical abuse puts a child at greater risk for developing a "victim personality".  相似文献

In 2 separate self-paced reading experiments, Farmer, Christiansen, and Monaghan (2006) found that the degree to which a word's phonology is typical of other words in its lexical category influences online processing of nouns and verbs in predictive contexts. Staub, Grant, Clifton, and Rayner (2009) failed to find an effect of phonological typicality when they combined stimuli from the separate experiments into a single experiment. We replicated Staub et al.'s experiment and found that the combination of stimulus sets affects the predictiveness of the syntactic context; this reduces the phonological typicality effect as the experiment proceeds, although the phonological typicality effect was still evident early in the experiment. Although an ambiguous context may diminish sensitivity to the probabilistic relationship between the sound of a word and its lexical category, phonological typicality does influence online sentence processing during normal reading when the syntactic context is predictive of the lexical category of upcoming words.  相似文献

Although numerous evidence‐based programs (EBPs) have been proven effective in research trials and are being widely promoted through federal, state, and philanthropic dollars, few have been “scaled up” in a manner likely to have a measurable impact on today's critical social problems. The Interactive Systems Framework for Dissemination and Implementation (ISF) explicates three systems that are critical in addressing the barriers that prevent these programs from having their intended public health impact. In this article we describe the relevance of these systems in a real‐world context with a specific focus on the Prevention Support System (PSS). We expand on the ISF model by presenting funders and policy‐makers as active and engaged stakeholders, and demonstrate how a state‐level PSS has used empirical evidence to inform general and program‐specific capacity‐building and support interactions among researchers, funders, and practitioners in Pennsylvania. By embracing this expanded ISF framework as a conceptual model for the wide‐scale dissemination and support of EBPs, and recognizing the need for a distinct state‐level PSS, Pennsylvania has created an infrastructure to effectively address the primary barriers to moving from lists of EBPs to achieving population‐level public health improvement.

Many studies have documented the links between dimensions of religiousness with mental health (e.g., Hackney and Sanders 2003; Mofidi et al. 2006). However, very little is known about whether these links differ across ethnic groups. This study examined the contribution of dimensions of religiousness to the prediction of mental health in an ethnically diverse sample of 413 college students (167 European Americans, 83 African Americans, 81 Asian Americans, and 82 Latino Americans). Results indicated significant ethnic differences across dimensions of religiousness. African Americans were significantly higher on religious engagement and religious conservatism than the other ethnic groups and significantly lower on religious struggle than European Americans. Moderated multiple regressions revealed that increases in religious struggle was associated with poorer mental health for African Americans and Latino Americans, while increases in religious engagement and ecumenical worldview were associated with better mental health for African Americans. The findings indicate that ethnicity is an important factor to consider when examining the link between religiousness and mental health.  相似文献

The existence of a phonemic deficit that is predictive of, and probably causal to, many cases of reading difficulty is well established. Tallal (1984) has suggested that this phonemic deficit is in fact a symptom of an underlying auditory temporal processing deficit. Our purpose in this paper is to evaluate the plausibility of this hypothesis. The various components that might constitute sequential (or temporal) processing are described. Our review of the literature reveals considerable evidence for a deficit in dyslexics in stimulus individuation tasks (e.g., gap detection) and temporal order judgments in both the auditory and visual modalities. The possibility that a general temporal processing deficit is associated with dyslexia, as suggested by Tallal (1984), is explored, and possible etiologies for such a deficit are discussed. The possibility of a causal link between temporal processing deficits and some reading disabilities is demonstrated, and converging evidence from morphological studies is reviewed. It is concluded that a temporal processing deficit does appear to be present in many developmental dyslexics, and strategies are suggested for further research aimed at evaluating the hypothesis that this deficit may be the root cause of a number of cases of dyslexia itself.  相似文献

Toddlers with language delay are at risk for persistent developmental and behavioral difficulties; however, the association between socioemotional/behavior problems and language in young children is not well understood. This study explored socioemotional/behavior problems in a unique sample of toddlers with language delays using a measure developed explicitly for this age group. Toddlers identified by 18 months with receptive and expressive language delay (LD; n = 30) or typical development (TD; n = 61) were evaluated at 18 and 24 months of age using the Infant‐Toddler Social and Emotional Assessment (ITSEA) and the Mullen Scales of Early Learning. Compared to toddlers who had TD, toddlers with LD had significantly more concerning scores at 18 and 24 months on all ITSEA domains. The rate of “clinical concern” on most domains was not high in either group, except that >60% of LD toddlers were in the clinical concern range on the Competence domain. Socioemotional/behavioral problems were dimensionally related to receptive and expressive language, with greater language delay associated with more concerning ITSEA scores. Socioemotional and behavioral problems are related to receptive and expressive language abilities in 18‐ and 24‐month‐olds, indicating the need for screening of both types of concerns in toddlers identified with potential language delays.  相似文献
