Monitoring Employee E-Mail: Efficient Workplaces vs. Employee Privacy

Employer monitoring of electronic mail constitutes an emerging area of the law that is clearly unsettled at this point in time. This iBrief demonstrates that the privacy rights of non public-sector employees are relatively unprotected by the federal and state constitutions, broad judicial interpretations of enacted privacy legislation favor legitimate employer-monitoring practices, and many of the elements of common law claims are difficult for employees to prove

Classification of Cohomogeneity One Manifolds in Low Dimensions

A cohomogeneity one manifold is a manifold with the action of a compact Lie group, whose quotient is one dimensional. Such manifolds are of interest in Riemannian geometry, in the context of nonnegative sectional curvature, as well as in other areas of geometry and in physics. In this paper we classify compact simply connected cohomogeneity one manifolds in dimensions 5, 6 and 7. We also show that all such manifolds admit metrics of nonnegative sectional curvature, with the possible exception of two families of manifolds

Dynamics of carbon dioxide exchange of a wheat community grown in a semi-closed environment

A wheat (Triticum aestivum Yecora Rojo) community was grown in the semi-closed conditions of the NASA/KSC Biomass Production Chamber (BPC). Experiments were conducted to determine whole community carbon dioxide exchange rates as influenced by growth and development, carbon dioxide concentration, time within the photoperiod, irradiance, and temperature. Plants were grown at a population of about 1500 per sq meter using a 20 hour light/4 hour dark daily regime. Light was supplied by HPS vapor lamps and irradiance was maintained in the range of 590 to 675 mu mol per sq meter. The temperature regime was 20 C light/16 C dark and nutrients were supplied hydroponically as a thin film. Fractional interception of PPF by the community increased rapidly during growth reaching a maximum of 0.96, 24 days after planting. This time corresponded to canopy closure and maximum rates of net photosynthesis (NP). Net daily CO2 utilization rates were calculated to day 48 and a 4th order regression equation integrated to obtain total moles of CO2 fixed by the community. This procedure may be useful for monitoring and prediction of biomass yields in a closed ecology life support system (CELSS)

State Fiscal Impact of the Succeed Scholarship Program 2016-2017

This report will address the fiscal impact of the SSP for the 2016-17 school year, the first year the program is available for students. As of February 2017 there were 22 students from 13 districts using the program to attend one of the 17 accredited private schools currently participating in the program. For 20 of the students we know which public school district he/she attended in 2015-16. All students must be attending a public school, relocating from out of state, or be members of an active duty military family in order to participate in the program. To estimate the fiscal effect of the program we compare the additional funding the local district would have received from the state if the SSP did not exist and compare it to the tuition cost covered thru the SSP. The difference is the net fiscal effect on the state

Squeezing the Public School Districts: The Fiscal Effect of Eliminating the Louisiana Scholarship Program on State Education Expenditures

Eliminating the Louisiana Scholarship Program (LSP) was proposed as a way to improve the financial situation of the Louisiana Department of Education budget in the current fiscal environment. A study released by the School Choice Demonstration Project (SCDP) found that the net fiscal impact on the Louisiana Department of Education budget would likely be an overall cost increase. In this study, we consider the effects that the removal or reduction of the program would have on individual districts. Districts would receive additional revenue from the state for affected students, but districts would also incur additional costs to educate these students. For each district, we compare the additional costs incurred to the additional funding received from the state. We conclude that the overall fiscal impact on districts will be negative; in other words, the overall additional variable costs incurred by the districts will be greater than the overall additional funding provided to the districts. In fact, we find that only 2 to 7 of the 69 school districts would benefit from the elimination of the program. For the affected districts, the average outcome would be a financial loss of about $1,500 per returning voucher student in 2016. In each scenario, we find that over 80% of student transfers would result in a financial loss for the local district. While we have framed this discussion in terms of the elimination of the LSP, the same analysis would be applicable to any situation that causes students to move from private schools to public schools in Louisiana, including the current funding cap which may force some current LSP students out of the program and has already generated a waitlist of over 400 students for next year

Impact of surface-polish on the angular and wavelength dependence of fiber focal ratio degradation

We present measurements of how multimode fiber focal-ratio degradation (FRD) and throughput vary with levels of fiber surface polish from 60 to 0.5 micron grit. Measurements used full-beam and laser injection methods at wavelengths between 0.4 and 0.8 microns on 17 meter lengths of Polymicro FBP 300 and 400 micron core fiber. Full-beam injection probed input focal-ratios between f/3 and f/13.5, while laser injection allowed us to isolate FRD at discrete injection angles up to 17 degrees (f/1.6 marginal ray). We find (1) FRD effects decrease as grit size decreases, with the largest gains in beam quality occurring at grit sizes above 5 microns; (2) total throughput increases as grit size decreases, reaching 90% at 790 nm with the finest polishing levels; (3) total throughput is higher at redder wavelengths for coarser polishing grit, indicating surface-scattering as the primary source of loss. We also quantify the angular dependence of FRD as a function of polishing level. Our results indicate that a commonly adopted micro-bending model for FRD is a poor descriptor of the observed phenomenon.Comment: 10 pages, 7 figures, presented at SPIE Astronomical Telescopes and Instrumentation, July 201

Photochemical Approaches to Complex Chemotypes: Applications in Natural Product Synthesis.

The use of photochemical transformations is a powerful strategy that allows for the formation of a high degree of molecular complexity from relatively simple building blocks in a single step. A central feature of all light-promoted transformations is the involvement of electronically excited states, generated upon absorption of photons. This produces transient reactive intermediates and significantly alters the reactivity of a chemical compound. The input of energy provided by light thus offers a means to produce strained and unique target compounds that cannot be assembled using thermal protocols. This review aims at highlighting photochemical transformations as a tool for rapidly accessing structurally and stereochemically diverse scaffolds. Synthetic designs based on photochemical transformations have the potential to afford complex polycyclic carbon skeletons with impressive efficiency, which are of high value in total synthesis.R01 GM073855 - NIGMS NIH HHS; R01 GM096129 - NIGMS NIH HHS; R35 GM118173 - NIGMS NIH HH
