Bats of the Jessieville Ranger District, Ouachita National Forest, Arkansas

During July and August 2000 and 2001, mist nets were set concentrated on three drainages in the Jessieville District of the Ouachita National Forest: North Fork Ouachita River (ten sites), Irons Fork Creek (five sites), and Muddy Creek (two sites). A total of 83 bats representing seven species was caught during 20 evenings (43 net nights). Sampled habitats included pools in road ruts, intermittent streams, man-made ponds on ridgelines, a wet road rut fed by a seep, small drainages that flowed only after a heavy rain, a standing pool in a clearing, and larger streams. Eastern red bats (Lasiurus borealis) were caught 64 times. Other bats caught included three evening bats (Nycticeius humeralis), eight eastern pipistrelles (Pipistrellus subflavus), two hoary bats (Lasiurus cinereus), three northern long-eared myotis (Myotis septentrionalis), one big brown bat (Eptesicus fuscus), and two Seminole bats (Lasiurus seminolus). A juvenile Seminole bat, only recently volant, represents the first documentation of likely reproduction of this bat in Arkansas

VuFind - Login Guerilla Test

The goal for this test was to determine how users perceive login when using the catalog, and at which access points it is best to force a login decision.Usability GroupUsability Task Forcehttp://deepblue.lib.umich.edu/bitstream/2027.42/106794/1/Login_guerilla_final.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/106794/2/Login_prelim_findings.pd

VuFind - Modified Card Sorting Labels Test

The goals for this test were to solicit suggestions from users for labeling facet categories, determine how users perceive the relative importance of facets, and determine how many narrowing terms users would like to see within each facet.Usability GroupUsability Task Forcehttp://deepblue.lib.umich.edu/bitstream/2027.42/106793/1/VuFind_Card_Sort.pd

Mirlyn Search Satisfaction Survey

The primary purpose of this survey was to gather information about how satisfied patrons are with search results in Mirlyn and whether satisfaction levels vary significantly between categories of users (i.e. undergraduates, graduate students, faculty, etc.). The survey was designed to measure satisfaction with searching overall and with two different kinds of searches: known item searches for specific items a patron already knows about and subject searches for items about a particular topic or subject.Usability GroupUsability Task Forcehttp://deepblue.lib.umich.edu/bitstream/2027.42/106782/1/MirlynSearchSurvey_Feb2011.pd

Mirlyn "Available Online" Label Guerilla Test

The goal of this guerilla test was to determine which of four labels (three alternate labels, in addition to the current “available online” label) denoting online availability is preferred by patrons, taking time to ensure that patrons understand the range of situations currently represented by the "available online" label. We also solicited suggestions for alternate labels from participants.Usability GroupUsability Task Forcehttp://deepblue.lib.umich.edu/bitstream/2027.42/106783/1/MirlynGuerillaTest_Feb2011.pd

A Perspective on Economic Impact

The institutions responsible for water resources management in the United States have originated as political responses to major social issues. Each agency institutionalized a procedure for structuring and comparing alternatives in the formulation of its total program. Each agency originally sought to promote effective resolution of its social issue (flood control, development of arid lands, soil erosion, etc.), but more recent efforts have sought better coordination among agency practices through a common procedure largely derived from economic theory. Any procedure, however, varies in application with the interpretation and judgment of individual planners. Today, public pressures have brought political directives requiring consideration of the local and nationwide impacts of projects that occur through direct, indirect, and secondary means in the spheres of economic, social and environmental effects. The body of the study reviews fourteen specific impact issues with the goals of providing planners a methodology for dealing with each one and of providing the theoretically inclined a basis for improving each methodology. The issues are reservoir effects on local property values, reservoir effects on the economy of the local county, changes in income and employment patterns around large reservoirs, patterns of land use change around reservoirs, reservoir effects on revenues and expenditures of local government, reservoir recreation benefits, application of marginal economic analysis to reservoir recreation planning, economic value of natural areas for recreational hunting, for stream fishing, the personal value of real property to its owner, reservoir project caused income redistribution, achievement of more flexible procedures for reservoir operation in order to match changes in demand for project output with time, estimation of flood damages by the time pattern in which they occur, and operation of reservoir systems for flood control. Each study ls presented in detail in a referenced report, and this report discusses the significance of the findings of the studies, individually and as a group

Insight into the mechanism of decarbonylation of methanol by ruthenium complexes; a deuterium labelling study

The authors thank Lucite international for funding.In the reaction of [RuHClP3] (P = PPh3) with NaOMe in methanol, the product is [RuH2(CO)P3]. Short reaction times show that the final product is formed through [RuH4P3] as the major intermediate. Using NaOCD3 in CD3OD, the first formed product is [RuH4P'3] (P' is PPh3 partially deuterated in the ortho positions of the aromatic rings). Further reaction leads to a mixture of [RuHnD2-n(CO)P3] (n = 0, 22 %; n = 1, 2 isomers each 28 %; n = 2, 22 %). Mechanistic aspects of both steps of the reaction are explored and, together with previously published calculations, they provide definitive mechanisms for both dehydrogenation and decarbonylation in these interesting systems.PostprintPeer reviewe
