Kinship and familiarity affect recognition and foraging in the wolf spider, Pardosa milvina (Araneae: Lycosidae).
No full textRecognition of familiar and related conspecifics can be crucial for altruistic
behaviors. In spiders, a reduction in cannibalism has previously been used as evidence of
kin recognition. The goal of this study was to examine the changes in activity and
foraging for the non-social wolf spider, Pardosa milvina (Araneae: Lycosidae), as novel
proxies for recognition and to provide evidence for altruism. Activity and foraging by
juvenile spiders were explored on chemotactile cues (silk, excreta, feces) from related
and/or familiar spiders. The activity of spiders included time spent moving, speed, and
duration on familiar or kin cues. Foraging included the maximum consumption of
crickets and rate of capture on non-kin, kin, familiar non-kin, and familiar kin cues.
Pardosa spent more time ambulatory on kin cues than familiar cues. Additionally,
animals foraging on kin cues decreased consumption while those foraging on familiar
cues increased consumption. Capture rates increased on familiar cues, but tended to
decrease on kin cues. These results suggest that immature Pardosa utilize chemotactile
cues to distinguish kin and familiar conspecifics and may exploit this recognition to
increase their indirect fitness. These results also align with a recent producer-scrounger
foraging model that considers within-group relatedness as a key to understanding
exploitation by kin. Together these results indicate a foraging strategy that may help to
explain the early evolution of sociality in spiders
Proper Footwear While Wearing an Orthopedic Walker Boot
No full textAs the use of Orthopedic Walker Boots increases it is important to study the effects of these boots. Walker boots have been shown to change kinetic and kinematic gait factors. However, the advantages of walker boots compared to casts often outweigh the possible negative effects of these changes. Specific advantages include the ease of application, easy adjustment to swelling and easy access for cleaning. Also, by maintaining some forces through the injured limb, proper healing can be encouraged. Besides the changes of gait, the decreased compliance and increased risk of falling are disadvantages that must be considered when using walker boots as treatment. The current study investigated the kinematic gait difference associated with walker boots and footwear worn on the opposite foot. The purpose of the study was the compare the changes in gait while wearing a walker boot and running shoe with the changes while wearing a walker boot and flip-flop. It was hypothesized that the flip-flops will lead to increased kinematic changes. To test this hypothesis, participants walked at self-selected speeds while motion capture systems were used to analyze the motion of the ankle, hip, knee and pelvic joints. Assessment of the self-selected speed indicates that there is a trend to support the hypothesis, but these differences are not significant to confirm the hypothesis.

This Relationship Isn’t Working … But Hopefully We Can Still Be Friends: How to Choose and Move to a New Vendor
No full textWith all of our daily tasks and special projects, assessing a vendor’s performance is probably the
last item on a library’s priority list. But with rapid technology growth and the budgetary
difficulties that libraries have faced in recent years, this overlooked task is becoming more
imperative. Last spring at our institution, it became apparent that we needed to work with a
larger serials subscription agency, and we began researching our options. In this presentation,
we will discuss vendor areas to evaluate including interface, costs and service. We will also
cover the vendor migration’s additional benefits including the improvement of our workflow
and the opportunity it provided for us to evaluate our serials collection in terms of usage,
format, scope and cost
DIY E-Resources: Break Out and Build Your Own
Get PDFThe options for libraries to create databases and access points far beyond the traditional ILS have expanded exponentially in the last few years. Library technical services departments can use their expertise to create their own e-resources that fit the needs of their constituent groups, whether in an academic environment, public library, or special library. Creating an eresource with simple, free platforms and tools is within the reach of any library without requiring advanced IT support. Learn how to create do-it-yourself e-resources using Wordpress and Omeka that can supplement the traditional catalog, house a variety of formats, and allow a flexible, user-centered approach to discovery and display of resources. Google Docs and Google Refine will be demonstrated as additional tools to streamline the creation and management of metadata
Adding “Free E-Books”: Providing User Access to Public Domain Hathi Trust Resources in the KentLINK and OhioLINK Catalogs
No full textAt the request of the OhioLINK Database Management and Standards (DMS) committee, Kent
State University Libraries began investigating the possibility and feasibility of loading
bibliographic records for public domain digital materials held by the Hathi Trust into KentLINK
and the OhioLINK central catalogs. This investigation led to the Hathi Trust project where, in
2010, Kent State successfully obtained and loaded over 470,000 bibliographic records for Hathi
Trust digital resources into both catalogs. The records were available at no cost, but an
investment was made in both time and resources to improve the quality of the records. This
made the Hathi Trust resources more discoverable for our patrons. This presentation will cover,
in detail, the issues and problems that needed to be addressed and resolved for this project.
Libraries working with or managing large files of bibliographic records for e-resources may
benefit from Kent State’s experience
Is There Value in Value Added Cataloging?
Get PDFAs with most libraries, the Grasselli Library holdings include many items with zero or very few
circulations. In particular, we were facing decisions about whether to withdraw numerous
items contained in monographic series. In contemplating ways to increase the visibility of these
items, we decided to test two methods of enhancing the catalog records of these items with a
goal of increasing circulation. The first method was to re-catalog monographic series previously
cataloged under the series title, in which individual volumes had unique titles. We added
access points for the unique titles, retaining a link to the bibliographic record for the series title
as well. As a pilot for this method, we chose to limit the process to the Q’s, as there were a
large number of instances of this situation in that area. The second method was to enhance the
records by adding table of contents fields. For this method, we chose the P’s as a pilot area,
due to the large numbers of items containing individual works for which our patrons might be
searching (i.e. plays, stories, etc.). We plan on evaluating the circulation statistics of these
items 12 to 18 months after enhancement to determine whether these practices are worth
implementing more broadly
Growing Up with Mark: Living with PDD-NOS
No full textAutism Spectrum Disorder, as a growing disability category in past years, has received a great deal of attention, in particular, for the classic autism disorder that most individuals have become so familiar with. However, it is rare that we hear about other disabilities that fall under the autism spectrum, such as Pervasive Developmental Disorder – Not Otherwise Specified, or PDD-NOS. Growing up with a sibling with this condition has been an impacting experience riddled with obstacles for every member of my family. However, it is through these experiences that I have grown and have developed to become the person that I am today. It is with this personal understanding and sincere interest in the disability that I elected to embark upon the task of creating a memoir surrounding the circumstances under which my brother grew up with his disability.
For the sake of creating a paper that would best capture the multiple perspectives of various members of my family, I elected to interview the various members of my family in order to create vignettes that best represented their perceptions of Mark. Each memory varies in length, from a sentence or two, to a full page. These memories are intended to capture the essence of Mark’s childhood and elementary school years. I hoped that through these memories, readers would be able to understand some of the thoughts that my family experienced as Mark grew up, as well as to give them some firsthand insight into the events that occurred during our lives over the years. I felt that through seeing how a family copes with a disability - going through the grieving process, struggling with the challenges posed, and celebrating the accomplishments – that the readers might get a more complete picture of how life can be impacted so profoundly by one such event. It is difficult to get perspective into such a difficult situation until one has lived through such an experience, and this is something I hoped could be shared through this memoir.
In order to give these vignettes more perspective, however, I realized that I could not simply list the vignettes one after another in written form. As a result, I elected to analyze each vignette from my own perspective. Therefore, each memory in italicized font is followed by my own analysis and additional relevant memories I have added to contextualize each described instance. In doing this, I hoped to not only provide more background on my family’s situation, but also to add some additional information on what might be expected of other families coping with a similar situation.
Through the format of a memoir centered around snapshots of Mark’s childhood, I hoped to make the delivery of this impacting experience as personal and relevant as possible to the readers, helping them to see the meaningful nature that is experienced by so many families who are impacted by the diagnosis of a disability
Investigation of Double Resonance Spectroscopy of Iodine Molecules for Use in Quantum Beat Experiments
No full textThe resonant B3PI+u to X0+g and resonant E0+
g to D02g to B3PI+u to X0+g transitions of I2 vapor have
been studied by direct observation of fluorescence emitted from the B, E and D' states,
respectively. Potential energy curves for the X0+g , B3PI+u , D0+u , D02g, A02u and E0+g states are calculated using Dunham coefficients from literature via the Rydberg-Klein-Rees Inversion
Method. The generated turning points are then used to calculate Franck-Condon factors and
Einstein A-coefficients. Both one and two-photon emission spectra are observed and analyzed
