The Decline Effect

Tuesday, December 21st, 2010

A hallmark of science is replicability. Another team of researchers following the same methods should be able to reproduce the original results. As Jonah Lehrer writes in The New Yorker, there may be a crippling flaw in this principle.

Lehrer gives examples from studies of the benefits of antipsychotics to the powers of ESP where subsequent experiments yield decreasing effects. This could be a case of muting the influence of outliers on data. But it’s so widespread that the decline effect points to something intrinsic to the practice of science.

John Ioannidis has written about the inherent biases in science. One article in PLoS Medicine entitled, Why Most Published Research Findings Are False, points to the way scientists influence data through their expectations. The preference of publishers for significant results also leads to inaccuracies. I would add that the mantle of objectivity also impedes scientists’ ability to accept the more qualitative elements of their craft.

Music and Healing

Monday, December 20th, 2010

We tend to think of teaching medicine as scientific training. But healing involves a holistic view of the patient. With that in mind, medical schools are integrating the arts into their curricula.

Studio 360, an NPR show, recently featured ways that medical students are learning about patient care through music, visual art, and narrative.

At BU, Robert Saper offers an optional course to students called the Healer's Art. His program in Integrative Medicine extends the approach to faculty development by inviting employees to participate in free weekly yoga classes.

Tracking Impact

Friday, December 17th, 2010

The Cited Reference Search in the database Web of Science allows users to track how many times a published work was referenced in the academic literature. It indexes journals from the humanities to the sciences and includes conference proceedings.

As complete as that sounds, does it really capture how scholars use academic literature? With so much content migrating online, we can now track other measures of impact like number of times an article was downloaded, blogged about, or linked to on a website.

InsideHigherEd.com describes new methods for assessing scholarly impact. One ranking uses a Google-like algorithm to weigh citations from prestigious journals most heavily. By that system, the New England Journal of Medicine comes out tops for medical journals in 2008.

CoolCite.com harnesses social networking by allowing researchers to upload their CVs and share content with other scholars. The site takes a holistic approach to evaluating merit by looking at the teaching and service part of an academic's record.

Curricular Change

Thursday, December 16th, 2010

The University of Texas Medical Branch at Galveston enrolls a much larger percentage of underrepresented minority students (25% compared to 15% nationally). Despite the success at recruiting a diverse student body, the medical school was not as accomplished in helping those students achieve. Only 2.9% of non-URM students failed the USMLE step 1 exam, but 16.6% of URM students failed.

In a study published in Medical Education, professors at Galveston report how they were able to boost those numbers so that 1.9% of non-URM students failed the exam and only 3.9% of URM students.

They implemented a wide-ranging rethinking of the curriculum, replacing a traditional memorization model with integrated learning. They incorporated problem-based learning and greater interaction with faculty. At the same time, the school invested in faculty development resources to equip teachers with skills in assessment and pedagogy.

The transformation did not happen overnight. The findings emerged from a comparison of students who matriculated between 1995-1997 and those who started between 2003-2005. But their experience shows how an institutional effort to improve learner outcomes can make a difference.

Evaluating Evaluations

Wednesday, December 15th, 2010

A study of students at the University of Northern Iowa and Southeastern Oklahoma State University found that a third of respondents on course evaluations lie. The Des Moines Register interviewed one of the authors, who said that the mistruths are more likely to be motivated by animus toward the faculty member than appreciation.

The findings confirm other research that questions the validity of student evaluations. In one study, good-looking professors outscored their more homely counterparts on year-end evaluations. The anonymous nature of the forms leads to some disparaging or simply bizarre comments. A colleague of mine received the feedback that, "Dr. X creates a wholesome, Christian environment." She wasn't sure if the remark was meant as satire or flattery.

Despite the shortcomings of student evaluations, trainees are in the best position to offer opinions about how teaching can improve. One solution might be to make the forms identifiable so respondents have to own their words. Another idea is for a neutral outsider to conduct focus groups or interviews with students about the course and summarize the suggestions for the faculty member.

A Global Flexner Report

Tuesday, December 14th, 2010

In the centennial year of Flexner's report on medical education, leaders in academic medicine have issued new calls for reform. The Carnegie Foundation issued a report this summer and this month a conference on Health Professionals for a New Century convened in Boston.

The conference organizers summarized their findings in an article in the Lancet. They found that worldwide 2420 medical schools train 1 million new physicians each year. The distribution of medical schools, however, do not match population. The U.S. has over 150 medical schools while 36 countries have no medical schools at all. Providing universal, high-quality health care, the authors argue, should be the goal of medical education.

This new phase of interdependent medical training involves a new kind of learning.

  1. First we had informational learning, which is the assimilation of facts and skills.
  2. Then comes formational learning, which prepares trainees to become professionals.
  3. The next step should be transformational learning, where trainees develop leadership attributes to serve as change agents.

The report does not offer many concrete suggestions for how to implement transformational learning or what changes it would mean for existing curricula. It seems that they mean to provide an overarching vision that will help shape global health citizens.

Diversifying Leadership

Monday, December 13th, 2010

Openly gay men and women now lead institutions of higher education as diverse as Hampshire College, Roosevelt University, and the University of Maine at Farmington. There are now enough LGBT college presidents (about two dozen), that the leaders held their own summit this year.

Michael Roggow has been interviewing gay and lesbian university presidents over the last two years and has come up with tips for both LGBT candidates for top positions and for search committees looking to signal inclusiveness.

For LGBT academics interested in leadership positions:

  • Let the search committee or search consultant know your sexual orientation, but focus on your accomplishments.
  • Find out as much as possible about the institution to determine if it's a good fit.
  • Develop a network of supportive friends.

For search committees interested in diversity:

  • Include welcoming language in the job description
  • Invite finalists to bring their partners to the interview
  • Value a candidate's accomplishments, not just personal characteristics.

These suggestions apply equally well to recruiting at the faculty level.

Award Winners

At the Evans Days Awards Dinner last night, the Department honored four faculty members for outstanding service.

Research Mentoring

  • Neil Ruderman, endocrinology, diabetes, and nutrition

Junior Faculty Mentoring

  • Marie McDonnell, endocrinology, diabetes, and nutrition

Special Recognition Teaching

  • Hap Farber, pulmonary, allergy, and critical care medicine

Outstanding Citizenship

  • Christine Campbell Reardon, pulmonary, allergy, and critical care medicine

All these honors began with a nomination. When the call for next year's awards goes out, please consider nominating an outstanding colleague. The AAMC publishes helpful guidelines for writing a persuasive nomination letter.

Tables of Contents

Thursday, December 9th, 2010

Put this in the category of technology that saves time rather than consumes it. There's a new website out of England called the Journal Table of Contents Service that helps scholars stay current with relevant publications. Best of all, it centralizes what has been a very scattered process.

Step 1: Enter the name of the journal you'd like to follow.

Step 2: Browse the titles and abstracts.

Step 3: Create custom alerts

Over 14,000 journals are in the database, and the program will send the list of contents to your e-mail, RSS feed, Google page, or blog. Once you set it up, you don't have to make further adjustments. Just scan the new contents for articles of interest.

Self-Plagiarism

Wednesday, December 8th, 2010

Faculty aiming for promotion often hear the advice, "Make it count twice." That is, if you develop a new curriculum, present it at a conference. If you make a conference presentation, turn it into a journal article. The idea is that once the effort has been expended, the reward should be maximized.

But how original should each piece of scholarship be? A story in Nature describes A Canadian professor of engineering who recycled much of the same content without acknowledgment in 20 different papers. The matter has led to discussions over how universities and journals can police duplicate submissions.

One biomedical researcher has developed software to detect similarities in published papers. Internet searches in general make self-plagiarism easier to detect. Perhaps as a result, the NIH has investigated zero instances of plagiarism in the last three years related to the 325,000 researchers it funds.
