Community and Adolescence in Four Societies
No full textThis study disputes the assumption that adolescence is a universal life stage as described by Erikson. Data were collected about twelve communities in four countries: the United States, India, New Zealand, and Romania. The findings suggest that there is a hierarchy of communities and societies, and that adolescence is socially constructed in each of these local settings
Changing Roles for Libraries: Providing Implementation and Ongoing Support for a Shared ETD Center at Two Ohio Universities
Get PDFThrough statewide cooperative programs, Ohio academic librarians have found themselves taking on new support roles not traditionally associated with the library. With OhioLINK’s centrally managed electronic thesis and dissertations (ETD) center, librarians have taken on new roles. The presenters will examine their role in supporting the implementation and maintenance of the ETD center at Miami University and The University of Toledo. Learn about the cultural changes involved in moving from paper to electronic theses and dissertations. Discover new roles for librarians as facilitators of change, even outside the library
A Study of Adult Guardianship in Ohio: Preliminary Results
Get PDFThis research brief is a description of findings from interviews with key informants from the first phase of a study entitled: “Adult Guardianship in Ohio: Promising Practices.” These findings led to the development of a survey about adult guardianship practices in Ohio's probate courts. The report highlights the challenges courts face and strategies they use to effectively manage those challenges. Finally, we highlight some promising practices that the courts have put in place to meet the challenges of managing adult guardianship
Ice-nucleating active bacteria decrease the cold-hardiness of stored grain insects.
No full textThis report provides further evidence that a freeze-dried, concentrated form of Pseudomonas syringae, an ice-nucleating active bacteria, reduces the cold tolerance of stored grain insect pests. Application of ice-nucleating bacteria to wheat or corn that contained insect pests decreased the insects’ supercooling capacity: after treatment with 100 ppm of P. syringae the mean supercooling points of five insect species increased from 4.7 to 11.9°C above untreated controls. Treatment with P. syringae also decreased the capacity of insects to survive a 24-h exposure to subzero temperatures. Decreases in cold tolerance were observed in eight species of stored grain pests: Indianmeal moth larvae, Plodia interpullctella (Hubner); red flour beetle adults, Tribolium castaneum (Herbst); flat grain beetle adults, Cryptolestes pusillus (Schon herr); rusty grain beetle adults, Cryptolestes ferrugineus (Stephens); Gibbium psylloides (Czenpinski); lesser grain borer adults, Rhyzopertha dominica (F.); yellow meal worm larvae, Tenebrio molitor (L.); and granary weevil adults, Sitophilus granariusgranarius (L.). Results of this study provide further support for the use of ice-nucleating active bacteria as biological insecticides to kill overwintering insects by decreasing their low temperature tolerance. The approach may be particularly appropriate for the control of a variety of insect pests in restricted areas such as grain bins
The Logistics of Supplying Single vs. Multi-crop Cellulosic Feedstocks to a Biorefinery in Southeast North Dakota
Get PDFThis study investigates the economics of supplying cellulosic crop residue feedstocks within 100 mile (or 161 km) radius of a potential new biorefinery in southeast North Dakota. We utilize linear programming transportation models and GIS (Geographic Information System) maps to identify optimal cellulosic feedstock supply sites for the biorefinery. Our evidence indicates that future crop residue removal policy will be important in assessing economic viability of harvesting crop residues for biofuel production. An increase in residue removal rate would narrow the size of supply areas required to provide total feedstock need for the biorefinery and consequently result in reducing transportation costs. There is an economic tradeoff between residue collection density and distance from the biorefinery. When multiple residue feedstocks are considered, this analysis is complicated further because greatest densities for each crop are not in similar regions. Overall, our findings show that higher costs savings can be achieved if multiple feedstocks are employed to produce cellulosic biofuels. In addition, feedstock supply risks can be lower with the use of multiple feedstocks
Recurring Sacral Stress Fractures in the Male Distance Runner
Get PDFReccurring Sacral Stress Fractures in the Male Distance Runner Waugh TJ, Stoller GL, Brooks EK, Dailey SW: Miami University Oxford, Ohio Background: A twenty year old male collegiate distance runner (170 cm and 62 kg) complained of low back pain in March 2015. The patient reported right sided low back tightness that felt like a bad spasm traveling from the lower back down into the lower leg. History of this runner revealed a non-displaced stress fracture in the left sacral ala with a stress reaction on the right sacral ala in November 2013. In April 2014, the distance runner possessed yet another sacral stress fracture. In March 2015, an assessment was made that the patient presented an acute case of piriformis syndrome due to lack of athletic participation. As two weeks went by with no positive results through rehabilitation, worsening pain, and given the pre-existing conditions of the patient, the Team Physician ordered an MRI. Differential Diagnosis: It is possible that the runner could have had an acute disc herniation, muscle strain, degenerative disc disease, or spondylolisthesis. A vertebral compression fracture, sacroiliac joint dysfunction, lumbar facet arthropathy, and sciatica are all differential diagnoses that the clinicians in this case needed to be aware of. It is also important to assess the possibilities of a lumbosacral strain and a sacroiliac joint sprain. Treatment: The MRI report revealed a high grade stress reaction in the right sacral ala. A non-displaced stress fracture in the right superior portion of the left sacral ala was also discovered. The patient was told to rest without any exercise for four to six weeks. After the stress fracture was resolved, the athlete has been encouraged not to participate in any repeated load-bearing types of activities until the source of the problem has been identified. Uniqueness: There is an uncommon nature of sacral stress fractures in males. It is important to realize that individuals who are constantly participating in repeating load-bearing activities are more prone to sacral stress fractures. Sacral stress fractures normally present themselves in women who have the female athlete triad. Research has shown that the influence of energy balance and hormonal fluctuations are significant factors associated with injuries in amenorrheic female athletes. The testosterone levels in young men normally lead to healthy and strong bones. This case report is a prime example that has the potential to teach clinicians all over to always look at the big picture and keep in mind all of the possible differential diagnoses. Conclusions: Physician's have hypothesized that the calcium level in this patient is too high which is causing parathyroid levels to decrease, resulting in low bone density. Since calcium and the parathyroid hormone have an inverse relationship, moderation between the two is essential. However, if one is too high, the other is too low decreasing bone density. Another hypothesis is that low testosterone levels in the patient are causing low bone density. This rare case is far from over as there is numerous investigative work to still be done. Clinical Application: Correctly diagnosing a sacral stress fracture is very difficult due to the wide range of differential diagnoses that its symptoms can present. Clinicians should never rule out the possibility of a sacral stress fracture when clients present low back pain, diffuse buttocks pain, and a history of repetitive loading actively. Although the clinicians in this case did not originally think this injury was another sacral stress fracture, they never ruled out the possibility due to the patient's described pain and pre-existing conditions. The clinicians in this report considered all possible diagnoses before making an assessment. Further research still needs to be performed in order to provide the most effective treatment and outcomes for future patients. Word Count: 59
