Fire History Study Reveals Surprises about Mixed-pine Ecology in Eastern Upper Michigan

Mixed red and white pine forests in eastern Upper Michigan saw frequent fires, about every 50–60 years, before Euro-American settlement. Post-settlement, the fire cycle has lengthened and forest composition has shifted to include more jack pine and fi re-sensitive deciduous trees, increasing fuel loadings and changing wildlife habitat along the way. In cooperation with researchers and land managers at Seney National Wildlife Refuge, researchers at The Ohio State University are working out details of combining mechanical treatments with prescribed fire to restore mixed-pine forests dominated by red and white pine. In particular, their findings about red pine ecology could change the way these forests are managed and restored. The researchers advocate mechanical fuels reduction in conjunction with broader ecosystem-based management objectives, such as restoring ecosystem integrity. The researchers will integrate these findings into an adaptive decision support tool to be used in the development of restoration-based fuel reduction recommendations

Interviewing Children about Repeated Events: Does Mental Context Reinstatement Improve Young Children’s Narratives?

This study examined mental context reinstatement (MCR) as a technique to increase the quantity and accuracy of information provided by children during repeated-event narratives. Children (N = 46, 4-, 5- and 6-year olds) participated in four repeated laboratory activities and were interviewed 4-7 days later about the last occurrence with a control or MCR interview, including both a free narrative and specific questions about the events. Older children (6-year olds) provided a greater number of accurate instantiations (specific details) compared to 4-year olds. Five and 6-year olds reported a greater number of instantiations than 4-year olds, but this effect was marginal. All children were equally accurate in both interview conditions. However, children in the MCR condition did not provide more information than controls, suggesting that 4-6-year old children may not benefit from the use ofMCR when interviewed about repeated events. Implications of the results and suggestions for future research are discussed

OT’s Role in a Social Enterprise Jobs Training Program for Homeless Youth

This capstone outlines a jobs training program for transition-aged youth (TAY), ages 18 – 25, currently residing at Urban Street Angels, a transitional housing facility for youth experiencing homelessness located in San Diego, California. The purpose of this project was to incorporate occupational therapy services into the site’s dormant social enterprise program, 8West. 8West produces a line of artisanal hand soaps created in-house by the youth living at Urban Street Angels. Through experiential and didactic learning, youth developed integral skills in customer service, communication, sales, marketing, professionalism, and production. The project addressed an unmet need for job skills training and development for TAY youth experiencing homelessness.https://soar.usa.edu/otdcapstonesfall2021/1012/thumbnail.jp

TREATMENT OF HEMOPHILIA WITH HUMAN FACTORIX PRODUCED IN MAMIMARY TISSUE OF TRANSGENIC MAMMALS

Recombinant Factor IX characterized by a high percentage of active protein can be obtained in the milk of transgenic animals that incorporate chimeric DNA molecules according to the present invention. Transgenic animals of the present invention are produced by introducing into developing embryos DNA that encodes Factor IX, such that the foreign DNA is stably incorporated in the DNA of germ line cells of the mature animal. Particularly efficient expression was accomplished using a chimeric construct comprising a mammary gland specific promoter, Factor IX cDNA that lacked the complete or any portion of the 5\u27-untranslated and 3\u27-un-translated region, which is substituted with a 5- and 3\u27-end of the mouse whey acidic protein gene. In vitro cell cultures of cells explanted from the transgenic mammal of the invention and methods of producing Factor IX from such said culture and methods of treating hemophilia B are also described

Developmental Differences in the Ability to Provide Temporal Information about Repeated Events

Children (n = 372) aged 4 - 8 years participated in 1 or 4 occurrences of a similar event and were interviewed 1 week later. Compared to 85% of children who participated once, less than 25% with repeated experience gave the exact number of times they participated, although all knew they participated more than once. Children with repeated experience were asked additional temporal questions and there were clear developmental differences. Older children were more able than younger children to judge relative order and temporal position of the four occurrences. They also demonstrated improved temporal memory for the first and last relative to the middle occurrences, while younger children did so only for the first. This is the first systematic demonstration of children’s memory for temporal information after a repeated event. We discuss implications for theories of temporal memory development and the practical implications of asking children to provide temporal information
