Alarm calling behavior of the thirteen-lined ground squirrel, Spermophilus tridecemlineatus
Alarm calling in a population of thirteenlined ground squirrels, Spermophilus tridecemlineatus , was studied over a three-year period. Data on ground squirrel reactions to human and canine approaches and to the approach or presence of avian predators were used to quantify alarm calling behavior.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/46905/1/265_2004_Article_BF00299364.pd

An overview of using small punch testing for mechanical characterization of MCrAlY bond coats
Considerable work has been carried out on overlay bond coats in the past several decades because of its excellent oxidation resistance and good adhesion between the top coat and superalloy substrate in the thermal barrier coating systems. Previous studies mainly focus on oxidation and diffusion behavior of these coatings. However, the mechanical behavior and the dominant fracture and deformation mechanisms of the overlay bond coats at different temperatures are still under investigation. Direct comparison between individual studies has not yet been achieved due to the fragmentary data on deposition processes, microstructure and, more apparently, the difficulty in accurately measuring the mechanical properties of thin coatings. One of the miniaturized specimen testing methods, small punch testing, appears to have the potential to provide such mechanical property measurements for thin coatings. The purpose of this paper is to give an overview of using small punch testing to evaluate material properties and to summarize the available mechanical properties that include the ductile-to-brittle transition and creep of MCrAlY bond coat alloys, in an attempt to understand the mechanical behavior of MCrAlY coatings over a broad temperature range
A multiple timepoint pre-post evaluation of a âsexual respectâ dvd to improve competence in discussing sex with patients with disability
Sexual problems are common after chronic illnesses and disability, yet research indicates that this is a neglected area in healthcare services. Evaluation studies provide evidence of the effectiveness of education in enhancing professionalsâ knowledge, skills, and comfort in addressing patientsâ sexual concerns. However, there are limited evaluations aimed at improving ability to discuss sexuality when working with people with disabilities. The overall aim of this study was to evaluate a âSexual Respectâ DVD as an intervention to improve competence in addressing âsexuality and disabilityâ. A mixed methods design was used with both quantitative and qualitative components. Nursing studentsâ self-report ratings of knowledge, confidence, comfort and willingness (to discuss sexuality) levels were collected across four time points: baseline, pre-intervention, post-intervention, and follow-up. Data were analysed using one-way repeated measures ANOVAs with post hoc comparisons. Open-ended qualitative comments relating to the barriers and facilitators to discussing sexuality were analysed using content analysis and subsequent frequency analysis. Reported barriers included lack of knowledge about sexÂŹuality and disability issues, the patientâs level of disability, and waiting for the patient to raise sexuality issues first. Facilitators included education/training, written information, and if the patient raised it first. Overall, the DVD intervention had a significant and positive impact on nursing studentsâ self-reported knowledge, confidence, comfort and willingness levels. The findings are discussed in relation to the PLISSIT model, which emphasises the importance of a proactive approach to addressing sexuality issues

Fuel pin behaviour under irradiation with high Pu content: Benchmark exercise
In Task 2.2, three fuel pins with high plutonium content are modelled using multiple fuel performance codes: CAPRIX, TRABANT1 pin 1, TRABANT2 pin 2. The objective of Task 2.2 is to increase the codesâ validation domain through code-to-code comparison, comparison to experimental data and, if possible, development/improvements of models. Comparison of the codes results with the experimental data allows estimation of the validity of the codes and identification of the set of settings that produce results in the best agreement with experimental data. This deliverable presents the results of the blind benchmark phase. The deliverable outlines the methodology adopted for this benchmark exercise, detailing the codes used, the requested outputs and sensitivity studies performed
