Insiders' Market Timing and Real Activity: Evidence from an Emerging Market

Earlier research on insider trading has documented unequivocally that officers, directors and controlling shareholders are in possession of valuable private information and exploit it profitably in security trading.1 It is widely believed that the apparent informational asymmetry arises from the foreknowledge of public disclosures. Consequently, a number of studies have investigated the intensity of insider trading prior to corporate events, such as takeover bids (Seyhun, 1990), dividend and earnings announcements (John and Lang, 1991; Ke, Huddart and Petroni, 2003), stock repurchases (Lee, Mikkelson and Partch, 1992), or bankruptcies (Seyhun and Bradley, 1997)

Integrating Statistics and Systems-Based Content in Undergraduate Medical Education Using a Novel Competitive Game—“The Study Puzzles”

Educators and professionals recognize the importance for inclusion of statistics in contemporary medical education programs and advocate its consideration for curricular integration. Given medical students’ perceptions about statistics, educators must explore pedagogical strategies that foster student engagement, ensure relevance of content, improve motivation and self-efficacy, and, ultimately, facilitate long-term retention of content knowledge. Games, with and without competitive elements, have been implemented successfully in both statistics and medical education. This paper presents a competitive game, known as “study puzzles,” that integrates statistics content with other systems-based content in the undergraduate medical education curriculum through the use of published research articles
