This article updates information about the Torrance Tests of Creative Thinking (TTCT) by reporting on predictive validity data from the most recent data collection point in Torrance’s longitudinal studies. First, we outline the background of the tests and changes in scoring over the years. Then, we detail the results of the analyses of the 40-year follow-up on the TTCT resulting in a structural equation model, which demonstrates the validity of the TTCT for predicting creative achievement 40 years after its administration. Finally, we provide a rationale for the relevance of the test in schools today.

This curriculum study of gifted-student learning in the language arts explores questions of curriculum efficacy related to the nature of the learner, the type of grouping model employed, and the strength of a curriculum treatment emphasizing literary analysis and interpretation and persuasive writing. The study further explores the use of curriculum effectiveness data to improve instruction the next time a unit of study is taught. Findings suggest that the curriculum treatment produces both significant and important learning outcomes for gifted students across 18 school district entities. Implications for further research and practice are highlighted.

Affected by the dramatic growth in waste electrical and electronic equipment (WEEE) and the gradual withdrawal of informal collectors, the traditional collection system appears to be undergoing an unprecedented decline in China. However, more than fifty internetbased collection entities have been founded in the past two years in China, reflecting the increased fusion of digital technology and traditional industries. Since these enterprises fully utilize digital technology, dynamic and profitable business ecosystems have been established to boost development. In this paper, two typical internet-based collection enterprises are chosen to represent the C2B (customer to business) and B2B (business to business) online collection models in China, allowing a comparative case study to be performed. The objective of this research is to analyze the structures, digital empowerment activities, and types of WEEE collection business ecosystems. One key result of our study is our map of the structure of WEEE collection business ecosystems, including the identification of key actors, such as suppliers, customers, online platforms, intermediaries and complementors, as well as the definition of links, such as information, material and money flow. The focal platform facilitates other actors by providing structural, psychological and resource empowerment. However, these business ecosystems differ in various ways, including with respect to the role of actors, the direction of information, material and money flow, the intensity of digital empowerment and platform position. Therefore, two types of business ecosystems are generalized: embedded business ecosystems and central business ecosystems. This study not only contributes to the existing business ecosystem literature by introducing digital empowerment but also expands the application areas of digital empowerment by investigating internet-based collection entities in China. Our results are theoretically important and have implications for the practical development of internet-based collection enterprises.
