trans-GZK Cosmic Rays: Strings, Black Holes, Neutrinos, or All Three?

We review the scenario in which ``strongly interacting neutrinos'' are responsible for inducing airshowers with inferred energies $E > 8\times10^{19}$ eV. This possibility arises naturally in string excitation models having a unification scale effectively decoupled from the Planck scale. We then show that phenomenological quantum gravity considerations reveal an equivalency of ``mini-black hole'' and strongly interacting neutrino pictures for explaining trans-GZK events. This equivalence can be exploited to predict single particle inclusive distributions. The resulting observable consequences in airshower development are studied using the Adaptive Longitudinal Profile Shower (ALPS) simulation.Comment: Talk presented at Cosmic Ray International Seminar (CRIS), Catania, Sicily, 2004; 6 pages, 6 figure

Evaluation of the REACH Program in Juvenile Detention

Although mentorship programs have been determined to be effective in promoting positive outcomes in youth and in decreasing delinquency, there is a significant gap in the literature in terms of implementation and evaluation of mentoring programs within juvenile detention facilities. The aim of our study is to evaluate the effectiveness of the REACH program, a violence prevention and delinquency intervention curriculum which the researchers implemented from September through December 2019 within the Porter County Juvenile Detention Center. The REACH curriculum is centered around four key program components: 1) Self-esteem enhancement, 2) Decision-making skills, 3) Setting post-release goals, and 4) Sense of support in working to achieve their goals. By surveying each child to measure their individual responses to each of the four main constructs before and after their participation in the REACH program for a minimum of two weeks, the researchers have been able to determine the effectiveness of the program in providing youth with positive skills that decrease their risk of recidivating. This research project not only provides a template for an effective juvenile delinquency intervention program but also may alter the life course of the youth who participate in the program. Successful implementation, evaluation, and promotion of the REACH program may provide other detention facilities outside of Porter County with an effective model and curriculum that could be implemented within their own detention facilities in order to decrease recidivism rates and strengthen their communities as well

AN EMPIRICAL ANALYSIS OF HONEYBEE POLLINATION MARKETS

Pollination by honeybees plays an important role in modern agriculture. Some crops are greatly dependent on honeybees (almonds, apples, avocados, blueberries, and cherries are examples) while the yields and quality of other crops are significantly enhanced by honeybee pollination. The importance of understanding pollination markets has increased recently due to changes brought on by the twin scourges of Varroa and tracheal mites. Both are infestations of feral and domestic bees that imply greater future reliance on domesticated bees at higher cost. In the United States a complex market has evolved that connects itinerant beekeepers and their bee colonies with farmers who demand their services. While the fields of entomology and crop science have developed a large literature on general principles of beekeeping and its application to particular crops, there has been little economic analysis of pollination markets. In this paper, we begin to remedy this lack of attention by analyzing an extensive panel data set of individual pollination transactions for Oregon beekeepers. The Oregon panel constitutes a considerably larger and richer data set on pollination markets than the data set examined by Cheung (1973), which is our only empirical precedent. Using cross-sectional time series regression models, we find results that are consistent with Cheungs earlier findings on the consistency of pollination market outcomes with economic theory. Fees charged for placing colonies on crops that yield marketable honey are found to be less than for crops that yield no honey income to the beekeeper: the pollination fee for crops that produce honey is about $17 per colony less than for crops that produce no honey. Pollination fees also vary over time in response to changes in both crop prices and honey prices. Because bees are paid according to their value of marginal product in the production of crops, pollination fees should vary positively with crop prices. We find that a ten percent increase in crop prices causes pollination fees to increase by about$.40 per colony. With respect to honey prices, we find that a ten percent increase is estimated to decrease pollination fees by about $2.50 per colony. This estimated effect is a previously unexplored link between the now-defunct honey program and its longstanding public policy rationale, the encouragement of honeybee pollination. Insofar as the honey program successfully maintained the price of honey above levels that would otherwise have been observed, our analysis suggests that elimination of the program has resulted in a reduction in pollination services and an increase in pollination fees.Marketing,

PS2: Managing the next step in the Pan-STARRS wide field survey system

The Panoramic Survey Telescope and Rapid Response System (Pan-STARRS) is unique among the existing or planned major ground-based optical survey systems as the only "distributed aperture" system. The concept of increasing system \'etendue by replicating small telescopes and digital cameras presents both management opportunities and challenges. The focus in this paper is on management lessons learned from PS1, and how those have been used to form the management plan for PS2. The management plan components emphasized here include technical development, financial and schedule planning, and critical path and risk management. Finally, the status and schedule for PS2 are presented.Comment: Paper presented at SPIE 2012 Astronomical Telescopes and Instrumentation, to be published in conference proceedings (8449-28

Signatures of Precocious Unification in Orbiting Detectors

It has been conjectured that the string and unification scales may be substantially lower than previously believed, perhaps a few TeV. In scenarios of this type, orbiting detectors such OWL or AIRWATCH can observe spectacular phenomena at trans-GZK energies. We explore measurable signatures of the hypothesis that trans-GZK air showeres (``anomalous showers'') are originated by strongly interacting neutrinos. The results of a MC simulation of such air showers is described. A distinction between proton induced and ``anomalous'' showers becomes possible once a substantial sample of trans-GZK showers will be available.Comment: LaTeX 2e, 14 pages, 5 figures.

Green Sea Turtles (Chelonia mydas) in Bermuda Exhibit an Ontogenetic Diet Shift despite Overexploitation of Resources in their Developmental Habitat

Green sea turtles in Bermuda are overgrazing the seagrasses on which later life stages are thought to specialize. I hypothesized that larger green turtles in Bermuda would display individual diet specializations during seagrass scarcity. Stable isotope methods were used to determine the diet composition of green sea turtles from the Bermuda Platform as a function of size class and in turtles captured in successive years. Individual turtles had a wide range of diets, however, the variation in diets was driven by differences among size class rather than within the size classes of larger turtles, indicating that green turtles undergo a dietary ontogenetic shift during their residency on the Bermuda Platform and no clear specialization of diets among late-stage individuals. The apparent lack of dietary specialization of larger turtles indicates that older turtles are not diversifying their diets in response to the drastic reductions in seagrass in Bermuda
