Oregon Parenting Education Collaborative: Helping Parents Raise Children Who Thrive

This report summarizes the work of the Oregon Parenting Education Collaborative during its first five years, 2010-2015. OPEC is a multi-year initiative led by The Oregon Community Foundation, The Ford Family Foundation and Oregon State University. Financial supporters include The Oregon Community Foundation, The Ford Family Foundation, the Meyer Memorial Trust, The Collins Foundation, and OCF Donor Advised Funds. The initiative supports expanded access to best practice parenting education programs, with a focus on reaching parents of children prenatal to age six, and supports efforts to develop and strengthen regional parenting education "Hubs." OPEC is unique in its collaborative, foundation-led approach to building a statewide infrastructure for parenting education through community-based non-profits and public agencies. The OPEC initiative was launched in July 2010 with the funding of six regional parenting Hubs serving 12 counties, and nine Small Grant projects providing evidence-based classes and/or home visiting for specific groups of parents. As of fall 2015, 15 Hubs reach 26 Oregon counties and Siskiyou County, Calif., and OPEC has provided Small Grant funding to 17 additional Oregon organizations. OPEC has achieved strong outcomes in the building of regional infrastructure and parenting education partnerships, as well as increasing positive parenting capacities

Effects of age, density, and seasonality on molt pattern in the mammal genus (Peromyscus)

Molting, or replacement of pelage (hair) in mammals, occurs during ontogeny as individuals transition from juveniles to adults. Environmental factors can cause variation in molt in many species for thermoregulatory and camouflage purposes. Within and among years molt can vary by time and age or by reproductive status. Past studies have found differences in molt pattern and timing depending upon age, and between captive reared and wild caught individuals. There has been little investigation into the molting characteristics of Peromyscus leucopus and P. maniculatus, specifically in comparison to adults and juveniles. I used molt observed from museum specimens collected at Bartlett Experimental Forest over a three-year period to determine if there are evident molt patterns in both Peromyscus spp. Specifically, I looked for differences in percent molt and number of individuals molting as a result of seasonality and age. Molts were digitized in Photoshop and pattern and symmetry were analyzed in ImageJ. In both species, individuals show a seasonal trend in molt timing and symmetry. This may reflect differences in resource availability and energy expenditure among years

Study of TADF Emitters in OLEDs

Delayed fluorescence through thermally activated delayed fluorescence (TADF) has great potential for the creation of inexpensive and highly efficient white lighting applications, with superior colour rendering. Currently the highest external quantum efficiencies are achieved with small donor-acceptor-donor molecules utilising intramolecular charge transfer (ICT) states, and these molecules require a suitable host matrix to reside in. This thesis studies the effect of host material on the model molecule 2d, a proven efficient TADF emitter through diligent photophysical investigation. A combination of steady state and nanosecond time resolved spectroscopic studies confirm the importance of a high host triplet level to ensure that the ICT state is the lowest energy excited state to avoid high levels of quenching. More interestingly it is shown that the functional group combination of emitter and host is crucial in achieving efficient TADF in OLED devices. In particular combinations where both the host and dopant are carbazole-based should be avoided due to the formation of carbazole dimer. The effect of such dimerisation is to lower the host triplet level significantly, and further to deactivate the ability of the 2d dopant to produce the ICT state required for TADF by locking the 2d dopant in the ‘planar’ configuration. It is therefore clear that the chemical composition of the host is of critical importance for the design of future OLED devices. Experiment also suggests that there is a complex interplay between exciplex and ICT emission in 2d systems in the solid state, insofar as CT emission of any description has so far only been observed in conditions where exciplex can and does occur
