Advancing Achievement Goal Theory: Using Goal Structures and Goal Orientations to Predict Students' Motivation, Cognition, and Achievement.

Abstract: The objective of this study was to investigate how different components of achievement goal theory were related to each other and to students' motivation, cognitive engagement, and achievement in mathematics. Junior high school students (N = 525) completed a self-report survey that assessed their perceived classroom goal structures; personal goal orientations; and a collection of outcomes that included persistence, procrastination, choice, their use of cognitive and metacognitive learning strategies, and mathematics grade. Results indicate that mastery structure and mastery orientation were related to adaptive outcomes in all areas. The patterns of relations for performance-approach goal structure, and for performance-approach and performance-avoidance goal orientations were less uniform across outcomes. Implications for achievement goal theory and future research are discussed.

Organizing for radical product innovation: the overlooked role of willingness to cannibalize

Abstract: Why are some firms more successful at introducing radical product innovations than others? Following Schumpeter (1942), many researchers have suggested that firm size is the key organizational pred...

Modelling flow pattern transitions for steady upward gas-liquid flow in vertical tubes

Abstract: Models for predicting flow pattern transitions during steady gas-liquid flow in vertical tubes are developed, based on physical mechanisms suggested for each transition. These models incorporate the effect of fluid properties and pipe size and thus are largely free of the limitations of empirically based transition maps or correlations.

Atomic cobalt on nitrogen-doped graphene for hydrogen generation

Abstract: Reduction of water to hydrogen through electrocatalysis holds great promise for clean energy, but its large-scale application relies on the development of inexpensive and efficient catalysts to replace precious platinum catalysts. Here we report an electrocatalyst for hydrogen generation based on very small amounts of cobalt dispersed as individual atoms on nitrogen-doped graphene. This catalyst is robust and highly active in aqueous media with very low overpotentials (30 mV). A variety of analytical techniques and electrochemical measurements suggest that the catalytically active sites are associated with the metal centres coordinated to nitrogen. This unusual atomic constitution of supported metals is suggestive of a new approach to preparing extremely efficient single-atom catalysts.
