Use of a Locally-Developed Worksheet for Multiple Journal Requests to Simplify the Review Process

Himmelfarb Health Sciences Library developed a worksheet to aid in making collection development decisions for the George Washington University Medical Center. This worksheet would enable the library to give priority to departments with less journal coverage. By conducting departmental surveys, the library was able to prioritize purchases regarding the journal collection. This poster presentation explains the development, results, and benefits of the worksheet, which was created in Microsoft Excel

Revising, Improving and Using a Locally-Developed Worksheet for Multiple Journal Requests to Simplify the Review Process

The Himmelfarb Health Sciences Library Serials Department implemented revisions to a previously developed worksheet used to aid in more effectively making collection development decisions. The worksheet as developed was used effectively, but subsequent questions and further input encouraged the original developer to identify additional parameters to measure, thus improving on the original worksheet. This poster presentation is a summary of the process and results of the improvements made to the worksheet

Development of non-damaging trapping apparatus and methods of limiting damage caused by traditional tangle nets in the spanner crab (Ranina ranina) fishery

Both male and female spanner crabs (Ranina ranina) readily moved up inclined ramps made from numerous materials and there were no significant size related behavioral differences. This suggested that Ranina ranina could be trapped in "entrance type" non­-entangling apparatus. A range of top and side entrance traps as well as conventional entanglement nets were trialed in the laboratory with entanglement nets entrapping over double the number of crabs caught in the most efficient non-entanglement trap tested. This was largely due to the greater time required by spanner crabs to find the entrance of a trap. Field trials supported the laboratory behavioural observations with no trap obtaining comparable catches to the conventional entangling apparatus. When fishing times of non-entangling traps were increased, catch rates likewise increased however the logistics and cost-effectiveness of their commercial use proved prohibitive. Field trails using different configurations of mesh size, numbers of mesh layers, ply and net tension for conventional entangling apparatus were also conducted to identify the most efficient net configuration for minimising damage whilst maintaining catch rates. Both small (25 mm) and large (85 mm) mesh size required more time to clear than intermediate sizes. Likewise dactyl loss was higher for these meshes, particularly the 25 mm mesh. Loosely hung nets induced over double the dactyl loss of tightly hung nets, with longer clearance time. In addition the catch of undersize crabs was also significantly greater in loosely hung nets whilst there was no significant difference in the catch of legal sized crabs. Tightly hung single mesh nets of a mesh size greater than 25 mm and less than 85 mm proved to be the most effective net for minimizing damage whilst maintaining catch rates

Molecular architecture of softwood revealed by solid-state NMR

Economically important softwood from conifers is mainly composed of the polysaccharides cellulose, galactoglucomannan and xylan, and the phenolic polymer, lignin. The interactions between these polymers lead to wood mechanical strength and must be overcome in biorefining. Here, we use 13C multidimensional solid-state NMR to analyse the polymer interactions in never-dried cell walls of the softwood, spruce. In contrast to some earlier softwood cell wall models, most of the xylan binds to cellulose in the two-fold screw conformation. Moreover, galactoglucomannan alters its conformation by intimately binding to the surface of cellulose microfibrils in a semi-crystalline fashion. Some galactoglucomannan and xylan bind to the same cellulose microfibrils, and lignin is associated with both of these cellulose-bound polysaccharides. We propose a model of softwood molecular architecture which explains the origin of the different cellulose environments observed in the NMR experiments. Our model will assist strategies for improving wood usage in a sustainable bioeconomy

Fulfilling the promise of applied developmental science: Is it time to reconsider our approach?

The promise of applied developmental science is that we can use scientific methods to promote positive human development and improve the lives of children and families. However, the present political environment in the United States makes the creation of research-informed federal policy difficult, even when the evidence supporting a given policy is unequivocal. In this essay, we hope to begin a conversation about how we, as applied developmental scientists, may modify our approach in order to best fulfill the promise of applied developmental science. To begin this conversation, we discuss the potential for establishing long-term partnerships with smaller entities, including state and municipal governments and non-governmental organizations to narrow the gap between what we know about children and families and the policies and programs that impact them. This \u27bottom-up\u27 approach has a long lineage in applied developmental science, and is currently enjoying a renaissance through the burgeoning interest in researcher-practitioner partnerships. Whether implicitly or explicitly, these partnerships often incorporate a systems perspective on children\u27s development; here, we review why embracing a systems perspective may increase the likelihood of crafting policies and programs that can improve the lives of children and families

Alcohol Sale Status and Homicide Victimization in Kentucky, 2005-2012: Is There a Spatial Association?

To date, the association between the alcohol sale status of decedents’ residence and alcohol-related homicide victimization have not been studied as far as we know. The current study aims to: i) determine whether homicide victims who were residents of wet counties had higher odds of testing positive for alcohol than their counterparts in moist or dry counties after adjusting for confounders; ii) determine whether homicides and alcohol-related homicides tend to cluster spatially; iii) determine whether the aforementioned associations exist only in highly-populated counties. A multilevel logistic regression analysis was used to analyze the data on homicide victims in the Kentucky Violent Death Reporting System from 2005 to 2012. Spatial statistics were used to determine the spatial autocorrelation in rates of homicides and alcohol-related homicides. Overall, 944 homicide victims were included. The male to female ratio was 3:1. About 32.8% of homicide victims tested positive for alcohol. About 33.0% of homicide decedents who were residents in wet counties tested positive for alcohol compared to 32.5% of their counterparts in moist/dry counties. Residence in wet counties was associated with a statistically insignificant increase in the unadjusted odds ratio (OR) of alcohol-related homicide victimization (OR=1.20, 95% CI=0.81-1.77) as well as the adjusted odds (aOR=1.33, 95% CI=0.83-2.12). There was no association between population size and alcohol-related homicide rate

Periodic Solutions of the Einstein Equations for Binary Systems

This revision includes clarified exposition and simplified analysis. Solutions of the Einstein equations which are periodic and have standing gravitational waves are valuable approximations to more physically realistic solutions with outgoing waves. A variational principle is found which has the power to provide an accurate estimate of the relationship between the mass and angular momentum of the system, the masses and angular momenta of the components, the rotational frequency of the frame of reference in which the system is periodic, the frequency of the periodicity of the system, and the amplitude and phase of each multipole component of gravitational radiation. Examination of the boundary terms of the variational principle leads to definitions of the effective mass and effective angular momentum of a periodic geometry which capture the concepts of mass and angular momentum of the source alone with no contribution from the gravitational radiation. These effective quantities are surface integrals in the weak-field zone which are independent of the surface over which they are evaluated, through second order in the deviations of the metric from flat space.Comment: 18 pages, RevTeX 3.0, UF-RAP-93-1
