technical Specialized Knowledge and founder leadership at initial public offering
2018Co-Authors: Jon Eckhardt, Marc JunkuncAbstract:This study examines factors that influence the likelihood that founders hold executive level positions in firms at the point of Initial Public Offering (IPO). Our model is conceptually more comprehensive than existing work, as we develop theory that examines founder involvement across executive positions beyond the often-studied chief executive officer (CEO). We examine our hypotheses using a database that contains virtually all IPOs spanning an 11-year period when the IPO market was active. Our empirical evidence indicates that a surprising number of founders hold leadership positions in firms at IPO. The research shows that factors that predict founder succession differ across executive positions.

technical Specialized Knowledge and secondary shares in initial public offerings
2009Co-Authors: Marc Junkunc, Jonathan T EckhardtAbstract:This paper utilizes an understudied but often utilized aspect of initial public offerings (IPOs), secondary shares, to examine whether the Knowledge conditions of firms give rise to agency problems that limit the ability of founders and venture capitalists to sell equity at IPO. In an analysis of 2,190 IPOs spanning from 1992 through 2002, we find that private owners are less likely to be observed selling their equity at IPO in ventures that are highly dependent on technical Specialized Knowledge as measured by the count of individuals with Ph.D.s in the top management team and board of directors. However, we find that this limit on the financial liquidity of founders and venture capitalists is alleviated when the venture's output has received greater market acceptance. Hence, the findings suggest that the financial liquidity of individuals involved in entrepreneurship is likely to be influenced by the Knowledge conditions of their venture.

managing radical innovation the importance of Specialized Knowledge in the biotech revolution
2007Co-Authors: Marc JunkuncAbstract:Abstract This work has implications for managers, investors and entrepreneurs in times of breakthrough innovation at the firm or industry level. The work shows that the marketplace understands the importance of retaining and motivating critical Specialized Knowledge. By analyzing initial public offerings during the biotechnology discovery wave I find evidence that a dramatic decrease in the ability to include secondary shares (liquidity for early investors and entrepreneurs) in biotechnology IPOs corresponds with the radical increase in the importance of Specialized Knowledge in that industry, at the time of the rDNA breakthrough discovery and development.

mathematical Specialized Knowledge of a mathematics teacher educator for teaching divisibility
2021Co-Authors: Marieli Vanessa Rediske De Almeida, Miguel Ribeiro, Dario FiorentiniAbstract:The Knowledge of Mathematics teachers has been a very prominent focus of attention in the last decades. However, it leaves aside one of the dimensions involved in the development of this type of Knowledge, specifically the Knowledge of Mathematics teacher educators. In this paper, we discuss a mathematics teacher educator’s Knowledge in the context of classes on Euclid’s division algorithm theorem in a Number Theory course for prospective secondary teachers. Some indicators of this Specialized Knowledge of mathematics teacher educators are presented and discussed.

multilayered Knowledge understanding the structure and enactment of teacher educators Specialized Knowledge base
2016Co-Authors: Sarah Selmer, Malayna Bernstein, Johnna BolyardAbstract:In order to corroborate and grow teacher educator Knowledge (TEK) scholarship, this paper describes an in-depth-focused exploration of a group of teacher educators providing professional development. Our grounded data analysis allowed us to define different major elements, sub-elements, and components that comprise TEK, as well as make explicit how the use of this Knowledge—in the context of teaching professional development—draws upon multiple components at any given moment. These findings hold implications for TEK scholarship and practice. Specific to scholarly efforts, while current models for TEK are useful for explicating common understandings amongst the research community, the most functional representations should be fluid and dynamic, in part by balancing both breadth and depth in their scope. Specific to the development of teacher educators, teacher educator preparation should recognize, emphasize, and develop future teacher educators’ layered understandings (i.e. Knowledge of students and teach...

the nature and predictors of elementary teachers mathematical Knowledge for teaching
2010Co-Authors: Heather C HillAbstract:This article explores elementary school teachers' mathematical Knowledge for teaching and the relationship between such Knowledge and teacher characteristics. The Learning Mathematics for Teaching project administered a multiple-choice assessment covering topics in number and operation to a nationally representative sample of teachers (n = 625) and at the same time collected information on teacher and student characteristics. Performance did not vary according to mathematical topic (e.g., whole numbers or rational numbers), and items categorized as requiring Specialized Knowledge of mathematics proved more difficult for this sample of teachers. There were few substantively significant relationships between mathematical Knowledge for teaching and teacher characteristics, including leadership activities and self-reported college-level mathematics preparation. Implications for current policies aimed at improving teacher quality are addressed.
