El Niño Causes Dramatic Outbreak Of Paederus Dermatitis In East Africa, Ingeborg M.C.J. Van Schayk, Ruben O. Agwanda, John I. Githure, John C. Beier, Bart G.J. Knols

All Peer-Reviewed Publications

An outbreak of Paederus sabaeus rove beetles in Kenya during the 1997-1998 El Niño resulted in a dramatic increase of vesicular dermatitis in its capital Nairobi. The beetle, popularly called ‘Nairobi Fly’, contains a potent toxic fluid that causes epidermolysis and acute conjunctivitis. A cross-sectional epidemiological study involving 1,208 Nairobi residents was conducted to determine the health impact of this outbreak. The results showed that one-third of the Nairobi population were infected during this period. The majority of the respondents reported lesions on exposed body parts above the shoulders. Disfiguring, painful blisters and skin rashes in and around the facial …

The results of statistical testing found that the relationship between the male candidates …

Passive Decisions And Potent Defaults, James J. Choi, David Laibson, Brigitte C. Madrian, Andrew Metrick

Faculty Publications

Default options have an enormous impact on household choices. Such effects have now been extensively documented in the literature on 401(k) plans (Madrian and Shea 2001; Choi et al. 2002b, 2004). Defaults have been shown to affect participation, savings rates, rollovers, and asset allocation. For example, Choi et al. (2004) study three firms that use automatic enrollment. When employees at these firms are automatically enrolled in their 401(k) plan, only a tiny fraction opt out, producing participation rates exceeding 85 percent regardless of tenure. But when employees at these firms were not automatically enrolled, participation rates were significantly lower, ranging …

Can Individual Investors Beat The Market?, Joshua D. Coval, David A. Hirshleifer, Tyler Shumway

Faculty Publications

We document strong persistence in the performance of trades of individual investors. The correlation of the risk-adjusted performance of an individual across sample periods is about 10 percent. Investors classified in the top performance decile in the first half of our sample subsequently outperform those in the bottom decile by about 8 percent per year. Strategies long in firms purchased by previously successful investors and short in firms purchased by previously unsuccessful investors earn abnormal returns of 5 basis points per day. These returns are not confined to small stocks nor to stocks in which the investors are likely to …

Configuring A Multi-Course Lab For System-Level Projects, Joel C. Adams, David W. Laverell

University Faculty Publications and Creative Works

Having students modify an actual operating system kernel or network protocol stack opens their eyes to what is going on "beneath the hood" of a computer. However student modifications to a system may result in an unstable computer. Because of this, giving students such experience has in the past required a lab and/or computers dedicated to the students in the system-level course, and computer science departments without such dedicated facilities have been unable to provide their students with system-level experience. In this paper, we present two ways of giving students system-level experience in a non-dedicated lab; one using commercial software …

Teaching French Film In A Christian Context: Cédric Klapisch’S Un Air De Famille, Jolene Vos-Camy

University Faculty Publications and Creative Works

Often, when viewing a foreign-language film, students are unable to pick up subtle cultural cues essential to the film’s message. If, however, students are well-prepared for a film, they become perceptive critics of the larger themes represented in the film. In this article I address pedagogical issues surrounding the use of Cédric Klapisch’s film, Un air de famille [Family Resemblances] based on my experience in teaching a new interdisciplinary course at Calvin College.

Applying The Information-Motivation-Behavioral Skills Model Of Hiv- Risk To Youth In Psychiatric Care, Geri R. Donenberg, Rebecca Moss Schwartz, Erin Emerson, Helen W. Wilson, Fred B. Bryant, Gloria Coleman

Psychology: Faculty Publications and Other Works

This study examined the utility of cognitive and behavioral constructs (AIDS in-formation, motivation, and behavioral skills) in explaining sexual risk taking among 172 12–20–year-old ethnically diverse urban youths in outpatient psy-chiatric care. Structural equation modeling revealed only moderate support for the model, explaining low to moderate levels of variance in global sexual risk taking. The amount of explained variance improved when age was included as a predictor in the model. Findings shed light on the contribution of AIDS informa-tion, motivation, and behavioral skills to risky sexual behavior among teens re-ceiving outpatient psychiatric care. Results suggest that cognitive and behavioral factors …

Effects Of Heavy Metal Accumulation On The 96-H Lc_50 Values In Tench Tinca Tinca L., 1758, Syed Lal Shah, Ahmet Altindağ

Turkish Journal of Veterinary & Animal Sciences

The effects of already accumulated heavy metals (Hg, Cd, Pb) in the body of tench on the 96-h LC_50 values of the respective heavy metals were studied. The body concentration of mercury, cadmium and lead was 0.011, 0.32 and 1.59 mg/g respectively, and their 96-h LC_50 values were 1.0, 6.5 and 300.0, ppm, respectively. The general accumulation order of heavy metals and their respective 96-h LC_50 values were Hg< Cd< Pb. It was observed that the fish with lowest body concentration of heavy metal showed the lowest 96-h LC_50 value of the respective heavy metal and vice versa. This close relationship showed that the previous body accumulation of heavy metals has a direct effect on the 96-h LC_50 values of the respective heavy metals and the susceptibility of fish.
