The ultimatum bargaining game: An adaptation for teaching ethics.

Purpose: The ultimatum bargaining game has been devised by economists to measure fairness and generosity during negotiations. This study sought to adapt the game to classroom application with the intent of (a) determining whether the known outcomes would be replicated given modifications needed to make the game suitable as an educational tool and (b) sharing the resulting self-appraisal with students themselves.

Methods: A total of 452 first-year dental students participated in this adaptation as part of a classroom exercise.

A question of intent: Application of the Knobe effect in teaching ethics.

Purpose/objectives: The Knobe effect refers to a measurable tendency among people to believe that undesirable side effects are brought about intentionally while desirable side effects are brought about unintentionally. People blame decision-makers for bad outcomes but do not credit them for good outcomes. The purpose of this study was to determine if the same is true for dental students and whether, as health care practitioners, students might mistakenly expect a benefit-of-the-doubt entitlement for themselves that the public is unwilling to bestow when an outcome is bad.

Access to care: leveraging dental education.

If it is not a naïve expectation for dentists who have been beneficiaries of public generosity to share their good fortune with the public that made it possible, there may be a rational basis for enhancing the role of dental education in improving access to oral health care by promoting-but not requiring-a voluntary service commitment after graduation commensurate with the magnitude of the subsidy received. Such an approach would be in accordance with the Institute of Medicine's report Improving Access to Oral Health Care for Vulnerable and Underserved Populations, but without the governmental coercion explicit in the report. A sustainable alternative proposal is made here, offering both greater options to students in the financing of their dental education and greater obligations for those students who accept state subsidies: providing tuition discounts for students of state-supported dental schools based not on past residency status but rather on a future commitment to public service.

Creating the dental school faculty of the future: a guide for the perplexed.

Building the faculty of the future has to be rooted in understanding the nature of future oral health delivery practices. Unfortunately, no one can reliably predict that future. Accepting any given scenario inevitably requires a leap of faith, but the cost of guessing wrong is high.

Why our ethics curricula don't work.

The impact our ethics curricula have on students seems marginal at best. Students take the ethics courses we offer and pass the tests we give, but no one's behavior changes as a result. We fundamentally see ourselves teaching about ethics, which is slightly different than teaching ethics--and expecting behavior to change as a result of what is taught.

Crosstalk of hypoxia-mediated signaling pathways in upregulating plasminogen activator inhibitor-1 expression in keloid fibroblasts.

Keloids are skin fibrotic conditions characterized by an excess accumulation of extracellular matrix (ECM) components secondary to trauma or surgical injuries. Previous studies have shown that plasminogen activator inhibitor-1 (PAI-1) can be upregulated by hypoxia and may contribute to keloid pathogenesis. In this study we investigate the signaling mechanisms involved in hypoxia-mediated PAI-1 expression in keloid fibroblasts.

Elevated vascular endothelial growth factor in keloids: relevance to tissue fibrosis.

Excessive scar or keloid shares common features of a benign dermal growth. Yet, in contrast to malignant tumor, a keloid does not expand beyond the dermis. What triggers the continuing growth of a benign lesion? Deficient or overabundant levels of vascular endothelial growth factor have been reported to contribute to impaired or excessive wound healing.

Mechanisms of hypoxic regulation of plasminogen activator inhibitor-1 gene expression in keloid fibroblasts.

Keloids are an excessive accumulation of extracellular matrix. Although numerous studies have shown elevated plasminogen activator inhibitor-1 (PAI-1) levels in keloid fibroblasts compared with those of normal skin. Their specific mechanisms involved in the differential expression of PAI-1 in these cell types.

The role and importance of research and scholarship in dental education and practice.

Understanding the role and importance of research and scholarship in dental education and practice requires an appreciation of dentistry as a learned profession. A foundational attribute for the members of such a profession has to be sheer intellectual curiosity--a trait as important for the clinician as for the scientist. That improved patient care results from technical advances made possible through research is not seriously disputed by anyone.
