Proposal To The Ethics Education In Science And Engineering Program, National Science Foundation: Role-Play Scenarios For Teaching Responsible Conduct Of Research, Michael C. Loui, C. K. Gunsalus

Ethics in Science and Engineering National Clearinghouse

We propose to develop and assess role-play scenarios to teach central topics in the responsible conduct of research (RCR) to graduate students in science and engineering. Together the scenarios will cover plagiarism, authorship, conflict of interest, interpersonal conflicts in mentoring, and concerns about compliance with research regulations on human participants in research, animal subjects, or hazardous substances. Two scenarios will present potential whistleblowing situations.

Intellectual merit: Few previous studies have carefully assessed the effectiveness of role-play in teaching ethics. We will conduct a rigorous, systematic assessment of role-play, using multiple methods, with a diverse group of graduate students. We will …

Motion Flow Estimation From Image Sequences With Applications To Biological Growth And Motility, Gang Dong, Tobias I. Baskin, Kannappan Palaniappan

Biology Department Faculty Publication Series

In this paper, a new method for motion flow estimation that considers errors in all the derivative measurements is presented. Based on the total least squares (TLS) model, we accurately estimate the motion flow in the general noise case by combining noise model (in form of covariance matrix) with a parametric motion model. The proposed algorithm is tested on two different types of biological motion, a growing plant root and a gastrulating embryo, with sequences obtained microscopically. The local, instantaneous velocity field estimated by the algorithm reveals the behavior of the underlying cellular elements.

The Quick And The Fast: The Evolution Of Acceleration Capacity In Anolis Lizards, Bieke Vanhooydonck, Anthony Herrel, Raoul Van Damme, Duncan J. Irschick

Biology Department Faculty Publication Series

Although of prime ecological relevance, acceleration capacity is a poorly understood locomotor performance trait in terrestrial vertebrates. No empirical data exist on which design characteristics determine acceleration capacity among species and whether these design traits influence other aspects of locomotor performance. In this study we explore how acceleration capacity and sprint speed have evolved in Anolis lizards. We investigate whether the same or different morphological traits (i.e., limb dimensions and muscle mass) correlate with both locomotor traits. Within our sample of Anolis lizards, relative sprint speed and acceleration capacity coevolved. However, whereas the variation in relative acceleration capacity is primarily …

Belladonna/(Lhx2) Is Required For Neural Patterning And Midline Axon Guidance In The Zebrafish Forebrain, Anandita Seth, Jay Culverwell, Mitch Walkowicz, Sabrina Toro, Jens M. Rick, Stephan Neuhauss, Zoltan M. Varga, Rolf O. Karlstrom

Biology Department Faculty Publication Series

Some of the earliest axon pathways to form in the vertebrate forebrain are established as commissural and retinal axons cross the midline of the diencephalon and telencephalon. To better understand axon guidance in the forebrain, we characterized the zebrafish belladonna (bel) mutation, which disrupts commissural and retinal axon guidance in the forebrain. Using a positional cloning strategy we determined that the bel locus encodes zebrafish Lhx2, a lim-homeodomain transcription factor expressed in the brain, eye, and fin buds. We show that bel(lhx2) function is required for patterning in the ventral forebrain and eye and that loss of bel …

The Ferm Protein Yurt Is A Negative Regulatory Component Of The Crumbs Complex That Controls Epithelial Polarity And Apical Membrane Size, Patrick Laprise, Siobodan Beronja, Nancy F. Silva-Gagliardi, Milena Pellikka, Abbie M. Jensen, C. Jane Mcglade, Ulrich Tepass

Biology Department Faculty Publication Series

The Crumbs (Crb) complex is a key regulator of epithelial cell architecture where it promotes apical membrane formation. Here, we show that binding of the FERM protein Yurt to the cytoplasmic domain of Crb is part of a negative-feedback loop that regulates Crb activity. Yurt is predominantly a basolateral protein but is recruited by Crb to apical membranes late during epithelial development. Loss of Yurt causes an expansion of the apical membrane in embryonic epithelia and photoreceptor cells similar to Crb overexpression and in contrast to loss of Crb. Analysis of yurt crb double mutants suggests that these genes function …

Mosaic Eyes Is A Novel Component Of The Crumbs Complex And Negatively Regulates Photoreceptor Apical Size, Ya-Chu Hsu, John J. Willoughby, Arne K. Christensen, Abbie M. Jensen

Biology Department Faculty Publication Series

Establishment of apical-basal cell polarity has emerged as an important process during development, and the Crumbs complex is a major component of this process in Drosophila. By comparison, little is known about the role of Crumbs (Crb) proteins in vertebrate development. We show that the FERM protein Mosaic Eyes (Moe) is a novel regulatory component of the Crumbs complex. Moe coimmunoprecipitates with Ome/Crb2a and Nok (Pals1) from adult eye and in vitro interaction experiments suggest these interactions are direct. Morpholino knockdown of ome/crb2a phenocopies the moe mutations. Moe and Crumbs proteins colocalize apically and this apical localization …
