Shareholder Wealth Effects of the Private Securities LitigationReform Act of 1995

Abstract: This paper investigates the reaction of stock prices to enactment of the Private Securities Litigation Reform Act of 1995 (PSLRA). Based on a sample of 489 high-technology firms, we find that the PSLRA was wealth-increasing, on average, and that the market reaction was more positive for firms at greatest risk of being sued in a securities class action. However, we also show that the PSLRA was less beneficial for firms likely to be the subject of a meritorious lawsuit. Collectively, our evidence implies that shareholders generally benefit from restrictions on private securities litigation, although these benefits are mitigated when other mechanisms for curbing fraudulent activity are inadequate.

Representational momentum and Michotte's (1946/1963) "launching effect" paradigm.

Abstract: In A. Michotte's (1946/1963) launching effect, a moving launcher contacts a stationary target, and then the launcher becomes stationary and the target begins to move. In this experiment, observers viewed modifications of a launching effect display, and displacement in memory for the location of targets was measured. Forward displacement of targets in launching effect displays was decreased relative to that of targets (a) that were presented in isolation and either moved at a constant fast or slow velocity or decelerated or (b) that moved in a direction orthogonal to previous motion of the launcher. Possible explanations involving a deceleration of motion or landmark attraction effects were ruled out. Displacement patterns were consistent with naive impetus theory and the hypothesis that observers believed impetus from the launcher was imparted to the target and then dissipated.

Incidence and prevalence of pressure ulcers in children.

Abstract: Objective To determine the incidence and prevalence of pressure ulcers in children. Design National survey mailed to 234 members of 4 pediatric-specific health care databases. Participants A total of 55 questionnaires were returned (25% return rate). Fifty-one of the questionnaires were suitable for obtaining prevalence data and 40 were suitable for obtaining incidence data. Results The pressure ulcer incidence rate was 0.29% and the prevalence rate for 1998 was 0.47%. Many of the contributing factors cited by participants mirrored those seen in adult patients with pressure ulcers. Conclusion Under the National Institutes of Health guidelines, children can be excluded from pressure ulcer studies that include subjects above age 21 because of the rarity of pressure ulcer development in the pediatric population. However, separate pediatric pressure ulcer studies should be conducted to determine best-practice models for children with pressure ulcers.

Instructional Feedback II: How Do Instructor Immediacy Cues and Facework Tactics Interact to Predict Student Motivation and Fairness Perceptions?

Abstract: During feedback interventions (FIs), instructors may feel torn between directing students’ learning or maintaining productive rapport with them. Existing research suggests how instructional communication can achieve both outcomes. This study examined how students’ motivation to learn and perceptions of fairness were enhanced or eroded via particular instructional behaviors. Actual face-threat mitigation (FTM) tactics and teacher nonverbal immediacy (TNI) cues were manipulated in differing combinations to manage an FI situation, with varying effects on the outcome variables. Multivariate analysis detected main effects and a significant interaction effect between FTM and TNI regarding students’ motivation to learn, but main effects only for their perceptions of interactional fairness. Theoretical and pedagogical implications are discussed in light of self-determination, facework, approach-avoidance, and feedback intervention theories.

The Effect of Goal Conflict on Performance

Abstract: The authors investigated the motivational effects of goal conflict in a complex goal performance setting. Goal conflict was found to have an indirect influence on performance through its relationship with goal commitment. Goal conflict was negatively associated with goal commitment when controlling for the other antecedents, including expectancy, self-efficacy, and need for achievement. As predicted, goal commitment and self-efficacy were related to goal-directed behaviors and goal-directed behaviors were related to performance. Performance was positively related to positive outcome emotions and negatively related to negative outcome emotions. The authors discuss the implications for the professional practitioner, theory development, and future research.
