The 2010 Benjamin Franklin medal in Computer and Cognitive Science presented to Shafrira Goldwasser,Ph.D.

The Franklin Institute, Philadelphia, Pennsylvania, awards the 2010 Benjamin Franklin Medal in Computer and Cognitive Science to Professor Shafrira Goldwasser for fundamental work contributing to the theoretical foundation of modern cryptography and leading to techniques that mathematically guarantee secure access to the internet. More precisely, she is recognized for key contributions in provable security and in particular for interactive and zero-knowledge proofs and their application to cryptography and complexity theory.     

Placement and frequency of powerless talk and impression formation

Study One examined the influence of initial use of hesitations and hedges on evaluations of witnesses and their persuasiveness in a budget hearing context. Results indicate that the negative attributions generated by the use of powerless language cannot be overcome by subsequent use of powerful talk. Study Two examined the relationship between the frequency of powerless language use and impression formation. For award/character and dynamism a perceptual threshold appeared to operate. The results of both studies suggest that auditors are very sensitive to the influence of powerless talk in formal settings.     

Teaching Prospect Theory with the Deal or No Deal Game Show

Recent evidence indicates that decision makers are more sensitive to potential losses than gains. Loss aversion psychology has led behavioural economists to look beyond expected utility by developing prospect theory. We demonstrate this theory using the Deal or No Deal game show.     

Characteristics of SAT Quantitative Items Showing Improvement After Coaching Among Black Students From Low-Income Families: An Exploratory Study

The present exploratory investigation is an extension of a 1985 study that evaluated a Scholastic Aptitude Test preparation program involving black urban students. The present study was conducted to determine if there are identifiable characteristics of quantitative items associated with a susceptibility to coaching. Items showing p-value improvements of. 10 after coaching were compared with items not showing such improvements; comparisons were made in terms of the content, type. format, level of cognitive requirement, and position of the items. Items showing improvement were found across content areas, formats, and type. Findings are discussed in relation to the usefulness and improvement of well-designed supplemental instructional programs that have the potential to affect criterion performance in mathematics     

Literacy Through the Book Arts

Children as readers and writers-and now as book artists too. Paul Johnson shows how children can be helped to learn the skills of book-making, thus empowering them as writers and illustrators by helping them to become the creators of beautiful books. The story grammars of different cultures include the way a story is laid out for people to read; Paul Johnson describes book designs from various cultures and shows how different book forms require children to read and tell stories in certain ways. Illustrations of various designs are shown within the article.     

Choice of Academic Major at a Public Research University: The Role of Gender and Self-Efficacy

Females are underrepresented in certain disciplines, which translates into their having less promising career outlooks and lower earnings. This study examines the effects of socio-economic status, academic performance, high school curriculum and involvement in extra-curricular activities, as well as self-efficacy for academic achievement on choices of academic disciplines by males and females. Disciplines are classified based on Holland’s theory of personality-based career development. Different models for categorical outcome variables are compared including: multinomial logit, nested logit, and mixed logit. Based on the findings presented here, first generation status leads to a greater likelihood of choosing engineering careers for males but not for females. Financial difficulties have a greater effect on selecting scientific fields than engineering fields by females. The opposite is true for males. Passing grades in calculus, quantitative test scores, and years of mathematics in high school as well as self-ratings of abilities to analyze quantitative problems and to use computing are positively associated with choice of engineering fields.
