The Results Are In! Updated Alternative I-O Graduate Program Rankings

In the summer of 2016, we issued a Call for Proposals to submit unique and innovative methodologies to rank I-O graduate programs. In response to this, many projects were proposed to us. After much hard work (and the broader SIOP community’s help), the five selected projects have been completed. Each of these five papers are included in the current issue of TIP. We believe each of these papers will be an important contribution to our field and will guide individuals in the future – as well as generate much thought and discussion about the state of our field and the programs that educate the future of IO Psychology. In particular, we hope that these rankings will result in graduate programs examining them-selves and thinking about ways they excel, as well as areas they could improve. Additionally, we hope that future undergraduate students applying to I-O programs will use these rankings, not to determine what the “best” programs are, but which programs are the best fit for them

I-O Graduate Program Rankings: Update

In the summer 2016 issue of TIP (Salter et al., 2016), we put out a Call for Proposals for updated I-O graduate program rankings. In this call, we were looking for new and unique methodologies for ranking I-O graduate programs that reflect the diversity of values and strengths across our field. We are pleased to announce we have conditionally accepted five proposals. Each of these teams will now conduct their project (which we hope all SIOP members will help with once data collection begins); we anticipate the final rankings will be published in the summer 2018 issue of TIP. Please note that the goal of this project is to make our methodologies public before data collection to reduce the likelihood of researcher degrees of freedom influencing the results. Although frequently unintentional, it is all too common for analytic decisions to be driven in part by the results that follow. Our goal is to achieve transparency in the way rankings were conducted and to present multiple methodologies, to aid students and educators in their decision making

Call for Proposals for I-O Graduate Program Rankings

Are you part of an I-O graduate program that is truly excellent, but the typical ranking systems do not necessarily show that? Would you like to help I-O psychologists (current as well as those who will be entering our field in the future) develop a better understanding of the different strengths of various graduate programs? We are issuing a Call for Proposals for rankings of I-O graduate programs. This is an excellent opportunity for graduate programs to highlight the ways in which they excel, and for individual SIOP members to help contribute to our field. In this Call for Proposals, we are seeking proposals for new and unique methodologies for ranking I-O PhD and MA/MS programs that reflect the diversity of values and strengths across the field of I-O. Multiple ranking methodology submissions will be accepted for publication, resulting in multiple rankings featured in an upcoming issue of TIP. We have developed this call in consultation with the TIP editor, in response to a need for more comprehensive and updated information about graduate programs

The RRAT Trap: Interferometric Localization of Radio Pulses from J0628+0909

We present the first blind interferometric detection and imaging of a millisecond radio transient with an observation of transient pulsar J0628+0909. We developed a special observing mode of the Karl G. Jansky Very Large Array (VLA) to produce correlated data products (i.e., visibilities and images) on a time scale of 10 ms. Correlated data effectively produce thousands of beams on the sky that can localize sources anywhere over a wide field of view. We used this new observing mode to find and image pulses from the rotating radio transient (RRAT) J0628+0909, improving its localization by two orders of magnitude. Since the location of the RRAT was only approximately known when first observed, we searched for transients using a wide-field detection algorithm based on the bispectrum, an interferometric closure quantity. Over 16 minutes of observing, this algorithm detected one transient offset roughly 1' from its nominal location; this allowed us to image the RRAT to localize it with an accuracy of 1.6". With a priori knowledge of the RRAT location, a traditional beamforming search of the same data found two, lower significance pulses. The refined RRAT position excludes all potential multiwavelength counterparts, limiting its optical luminosity to L_i'<1.1x10^31 erg/s and excluding its association with a young, luminous neutron star.Comment: Submitted to ApJ, 7 pages, 5 figure

Eulerian modeling of charge transport in bi-disperse particulate flows due to triboelectrification

An Eulerian model to describe the behavior of electrically charged particles, which considers charge separation and transfer between particles of two separate species, is developed using the kinetic theory of granular flows. A transport equation for the charge of each particle species is obtained, incorporating the effect of the charge–velocity correlation. Closures for the collisional diffusion of charge and for the charge-velocity covariance are obtained. The developed model is applied to steady-state simulations in a one-dimensional domain with no advection, neglecting momentum transport and assuming a constant granular temperature for the solid species. While this is only a preliminary test of the model, which will require further validation, the results show the prediction of bipolar charging when the particles have different sizes, even though they are made of the same material. This phenomenon is analyzed and is shown to be driven by the electric field produced by the charge accumulated on the particles.This article is published as Ray, M., F. Chowdhury, A. Sowinski, P.
