Countering the Global Landmine Epidemic Through Basic Scientific Research

Since their first use during the U.S. Civil War (Croll 1998), blast landmines have played a role in almost every armed conflict from the World Wars to the most recent limited skirmishes. Landmines are the epitome of the consummate soldier: always ready, never tiring. Mines are simple devices that can be fabricated with little effort and from readily available materials. In Sri Lanka, numerous news releases covering the conflict mention a Johnny mine (Botsford 1997), which is a local term for an improvised explosive device. Manufactured mines can be inexpensive, costing as little as two dollars apiece. If mine laying operations ceased tomorrow, an estimated 100 million mines would remain in place throughout the world (United Nations 1994)

Experiential Learning through Short-Term Study Abroad: A Business Approach

Excerpt Passarelli and Kolb (2012) suggest that an experiential education model can be useful in designing and assessing study abroad programs. As business school professors in the Driehaus College of Business at DePaul University who direct and assess short-term study abroad programs, we could not agree more. Our global framework not only encourages students to leave their comfort zones and experience unfamiliar cultural environments, but they are also provided with opportunities to explore issues of academic and business interest with academic, governmental, business, and non-business leaders in other countries. Moreover, they can also observe how public and private organizations operate in various parts of the world. Through study abroad, students leave the classroom, interact with key leaders in their countries, and learn through engagement, discussion, and immersion. The purpose of this paper is to explain how short-term study abroad programs developed in our college provide such possibilities for busy undergraduate and graduate students; moreover, we provide suggestions for professors wishing to implement similar programs at their own institutions

Validity, Significance, Strengths, Limitations, and Evidentiary Value of Real-World Clinical Data for Combination Therapy in Alzheimer's Disease: Comparison of Efficacy and Effectiveness Studies

Background: Randomized controlled efficacy trials (RCTs), the scientific gold standard, are required for regulatory approval of Alzheimer's disease (AD) interventions, yet provide limited information regarding real-world therapeutic effectiveness. Objective: To compare the nature of evidence regarding the combination of approved AD treatments from RCTs versus long-term observational controlled studies (LTOCs). Methods: Comparisons of strengths, limitations, and evidence level for monotherapy [cholinesterase inhibitor (ChEI) or memantine] and combination therapy (ChEI + memantine) in RCTs versus LTOCs. Results: RCTs examined highly selected populations over months. LTOCs collected data across multiple AD stages in large populations over many years. RCTs and LTOCs show similar patterns favoring combination over monotherapy over placebo/no treatment. Long-term combination therapy compared to monotherapy reduced cognitive and functional decline and delayed time to nursing home admission. Persistent treatment was associated with slower decline. While LTOCs used control groups, adjusted for multiple covariates, had higher external validity, and favorable ethical, practical and cost considerations, their limitations included potential selection bias due to lack of placebo comparisons and randomization. Conclusions: Naturalistic LTOCs provide complementary long-term level II evidence to complement level I evidence from short-term RCTs regarding therapeutic effectiveness in AD that may otherwise be unobtainable. A coordinated strategy/consortium to pool LTOC data from multiple centers to estimate long-term comparative effectiveness, risks/benefits, and costs of AD treatments is needed

Inelastic interaction mean free path of negative pions in tungsten

The inelastic interaction mean free paths lambda of 5, 10, and 15 GeV/c pions were measured by determining the distribution of first interaction locations in a modular tungsten-scintillator ionization spectrometer. In addition to commonly used interaction signatures of a few (2-5) particles in two or three consecutive modules, a chi2 distribution is used to calculate the probability that the first interaction occurred at a specific depth in the spectrometer. This latter technique seems to be more reliable than use of the simpler criteria. No significant dependence of lambda on energy was observed. In tungsten, lambda for pions is 206 plus or minus 6 g/sq cm
