Patron-Driven Acquisition Optimization and Workflows at Liberty University Jerry Falwell Library

In the spring of 2010, the Liberty University Jerry Falwell Library began a pilot patron-driven acquisition program with the e-book aggregator ebrary. In the fall of 2012, the program had been active for two years, and the librarians sought to optimize the program in the form of selecting more titles which are used. This paper describes the formula that the librarians used to achieve optimization in the PDA program. Also described is the workflow involved with acquisitions and cataloging before and after the purchases are made

The Effects of Environmental Regulation on Technology Diffusion: The Case of Chlorine Manufacturing

We use a hazard model to estimate the effect of environmental regulation on the diffusion of membrane cell production technology in the chlorine manufacturing industry. We estimate the effect of regulation on both the adoption of the membrane technology at existing plants and on the exit of existing plants using older technologies. We find that environmental regulation did affect the diffusion of the cleaner technology in the chlorine industry. However, it did so not by encouraging the adoption of membrane cells by existing facilities, but by reducing the demand for chlorine and hence encouraging the shutdown of facilities using the environmentally inferior options.Regulation, Technological change, Environment, Hazard model

Private Options to Use Public Goods: Exploiting Revealed Preferences to Estimate Environmental Benefits

We develop and apply a new method for estimating the economic benefits of an environmental amenity. The method fits within the household production framework (Becker 1965), and is based upon the notion of estimating the derived demand for a privately traded option to utilize a freely-available public good. In particular, the demand for state fishing licenses is used to infer the benefits of recreational fishing. Using panel data on state fishing license sales and prices for the continental United States over a fifteen-year period, combined with data on substitute prices and demographic variables, a license demand function is estimated with instrumental variable procedures to allow for the potential endogeneity of administered prices. The econometric results lead to estimates of the benefits of a fishing license, and subsequently to the expected benefits of a recreational fishing day. In contrast with previous studies, which have utilized travel cost or hypothetical market methods, our approach provides estimates that are directly comparable across geographic areas. Further, our results suggest that the benefits of recreational fishing days are generally less than previously estimated.

Use of the International Space Station as an Exercise Physiology Lab

The International Space Station (ISS) is now in its prime utilization phase with great opportunity to use the ISS as a lab. With respect to exercise physiology there is considerable research opportunity. Crew members exercise for up to 2 hours per day using a cycle ergometer, treadmill, and advanced resistive exercise device (ARED). There are several ongoing exercise research studies by NASA, ESA and CSA. These include studies related to evaluation of new exercise prescriptions (SPRINT), evaluation of aerobic capacity (VO2max), biomechanics (Treadmill Kinematics), energy expenditure during spaceflight (Energy), evaluation of cartilage (Cartilage), and evaluation of cardiovascular health (Vascular). Examples of how ISS is used for exercise physiology research will be presented

Evaluating Environmental Policies

For too long, environmental policymaking has relied on trial and error, without adequate or systematic learning from either the trials or the errors. Systematic program evaluation research has been remarkably scarce relative to the overall number of environmental policies adopted in the United States, as well as relative to the amount of evaluation research found in other fields, such as medicine, education, or transportation safety. This paper examines the role that program evaluation should play in environmental policy making, distinguishing such research from other types of analysis, including risk assessment, cost-effectiveness analysis, and cost-benefit analysis. It explains the kinds of methodological practices that researchers should use to isolate the causal effects of particular environmental regulations and policies. By adhering to the program evaluation methods discussed in this paper, researchers will be better able to isolate the effects of specific policy interventions and help inform future policy decisions. A renewed and expanded commitment to program evaluation of environmental policy is needed to move environmental policy making closer to an evidence-based practice, and conditions are probably more ripe now for fostering such a commitment than they have ever been before

Effects of Sex and Gender on Adaptation to Space: Musculoskeletal Health

There is considerable variability among individuals in musculoskeletal response to long-duration spaceflight. The specific origin of the individual variability is unknown but is almost certainly influenced by the details of other mission conditions such as individual differences in exercise countermeasures, particularly intensity of exercise, dietary intake, medication use, stress, sleep, psychological profiles, and actual mission task demands. In addition to variations in mission conditions, genetic differences may account for some aspect of individual variability. Generally, this individual variability exceeds the variability between sexes that adds to the complexity of understanding sex differences alone. Research specifically related to sex differences of the musculoskeletal system during unloading is presented and discussed
