We report on the specific interaction between DNA and some mica-family minerals and other layered silicate structures. The interaction depends on mineral surface's crystallography, chemistry and potential. These properties are responsible for a remarkable variety of adsorption mechanisms and can be used to modulate surface self-assembly and nanopatterning of DNA. The controlled deposition of DNA onto non-conductive mineral regions with atomically flat boundaries has very attractive applications in nano-biotechnology (for example, microelectronics, microarrays and sensors). In addition, the extreme affinity discovered for some mineral surfaces, together with their ability to organize the DNA molecules, could be an indication of their catalytic potential. It may also have had relevance in the prebiotic environment, with important implications for the earth and life sciences. 相似文献

In this study, self-determination theory was used as a guiding framework to understand the putative role of relatedness support for retention in golf among young females. Data were collected using semi-structured interviews with 10 female participants (Mage = 21.40, SD = 3.13). Content analyses revealed 5 distinct factors that contributed to the provision of relatedness support: Parents, Peers, Coaches, Golf Club, and Institutional and Societal Support. Findings highlighted that retention of female golfers may be facilitated through promoting valued relationships with parents, peers, coaches, and golf clubs. Policies that decrease the perceived marginalization of female participants may also be perceived as a form of relatedness support and may promote retention within this cohort. This study underscores the importance of relatedness support for young women and identifies strategies that may help to improve female retention in sport. 相似文献

What do social networking sites reveal about the relation between the self and the community? We conceptualise social networking sites as technologies of the self and the community enabling individuals to self‐present and also objectifying the community's evaluation of individuals (through ‘structures of recognition’ such as page views, friends and lovehearts). We analyse the way in which 37 Scottish adolescents used the social networking site Bebo in nonprescribed and creative ways. First, they challenged the single authorship of profiles by co‐creating multi‐authored profiles. Second, they used creative language to obscure meaning from the preying eyes of parents, teachers and potential employers. We conclude by discussing the simplistic assumptions that Bebo makes about the relation between the self and the community. In contrast, newer social networking sites such as Facebook and Google+ are increasingly enabling people to present different facets of themselves to different communities. How people use social networking sites, and how these sites are developing to attract more users, reveals how the multiplicity of human identity is related to the multiple communities that people participate in.

AbstractCorruptogenic organizational dynamics have been largely ignored in reporting about recent corporate scandals. Using a large group framework, the author identifies factors within an organization that create a breeding ground for unethical or illegal behavior and attract individuals unconsciously looking for ways to damage themselves or others. An organizational culture that promotes questionable attitudes and behaviors along with subgroups that produce powerful corruptive forces can destroy a firm and damage the economy. Enron and the Madoff investment group are identified as corruptogenic organizations put together by founders and a leadership core bent on self-destruction and traumatizing the community–outcomes beyond that which are usually linked to greed. Suggestions are provided to organizational consultants and policy makers as to how to determine the potential for corruption hidden in their midst and to implement countervailing structures and processes. 相似文献

AbstractThis paper explores the trend away from offering process-oriented groups on inpatient units, given decreasing lengths of stay, increasing acuity levels, and current biases toward psychoeducational groups and cognitive-behavioral treatments. A model for doing process-oriented groups that provides a structure while allowing a theme to emerge and maximal interaction to take place is presented. A case is made for the benefits of process-oriented inpatient groups as compared to, and complementary with, psychoeducational, cognitive, and behavioral approaches. Clinical vignettes illustrate typical themes and dynamics emerging in process-oriented inpatient groups. 相似文献

Popular theory on the tendency to cradle an infant to the left side points to the specialization of the right hemisphere for the perception and expression of emotion. J. S. Sieratzki and B. Woll (1996) recently suggested that more emphasis be placed on the auditory modality, specifically focusing on the role of prosodic information. In this study, the direction of the lateral cradling bias in a group of profoundly deaf children, a group of deaf adults, and a control group of adults with no hearing impairment was investigated. The authors found a strong leftward cradling bias in all groups, a bias that was, if anything, stronger in the deaf participants. Given that people who are profoundly deaf, especially those who have been deaf from birth, have not been exposed to auditory prosody, the data do not support the suggestion that such prosodic information is the basis for the leftward cradling bias. 相似文献

The author identified profiles of chronic illness knowledge (i.e., heart disease, cancer, diabetes) in a community sample of American adults and examined the effect of sociodemographic influences on relations of illness knowledge to health practices and well-being. Participants were 181 women and 120 men who completed measures of illness knowledge, sociodemographics, personal health practices (e.g., diet, exercise, substance abuse, adaptive healthcare use), well-being (e.g., self-rated physical health, depression, social support), and perceived illness risk. Two-step cluster analyses performed on random subsets of the sample identified three levels of illness knowledge: low, medium, and high. Knowledge groups were differentiated on most measures of health practices, well-being and perceived illness risk. However, effects were substantially attenuated after controlling for differences in age and SES. Findings indicate that age and other sociodemographic factors are related not only to levels of illness knowledge but also to the application of knowledge in relation to health practices and well-being. 相似文献

The purpose of this study was to subclassify clinically depressed patients based on a cluster-analytic examination of the MMPI. Subjects were 79 female inpatients with major depression. A cluster analysis of the MMPI validity and clinical scales resulted in three clusters labeled psychotic (287 MMPI profile), hostile (24 MMPI profile), and histrionic (32 MMPI profile) depression. The psychotic group exhibited the greatest depression as measured by the Beck Depression Inventory (BDI). The psychotic and hostile groups, however, did not differ on other associated aspects of depression, such as negative cognitions, nonassertiveness, or personality style. The hostile group reported the fewest physical difficulties and the most excessive alcohol use. The groups, however, did not differ on other aspects of depression history or presentation such as family history of depression or previous hospitalizations. A repeated measures ANOVA for the three cluster groups on the BDI at admission, discharge, and 6 months after discharge indicated that all groups showed improvement at discharge but that only the hostile depressive group continued to show improvement at the 6-month follow-up. 相似文献

Although numerous studies have attempted to understand the causes of various forms of police misconduct, there is still no clear theoretical explanation of police misbehavior. Akers’ social learning theory posits that peer associations, attitudes, reinforcement, and modeling are predictors of delinquency and crime in general. With this article, we seek to determine if the theory can account for police deviance. Data from a random sample of Philadelphia police officers are used to examine how officer attitudes and perceptions of peer behavior are related to citizen complaints of police misconduct. Findings suggest that social learning theory provides a useful explanation of police misconduct. 相似文献
