In rapid serial visual presentation, identification of the second of two targets is impaired when it closely follows the first target. This phenomenon is known as the attentional blink (AB) effect. Awh and his colleagues (2004) found that face discrimination was immune to AB when performed together with a digit...
A method for large quantity dsRNA production was developed since a small amount of dsRNA synthesized in vitro with commercial kits are used for small scale bioassay evaluations. Developing a large-scale production system for dsRNA is critical for practical RNAi application, especially for non-transgenic RNAi-based control. However, large-scale analysis or...
The social and medical models of disability are sets of underlying assumptions explaining people's beliefs about the causes and implications of disability. The medical model is the predominant model in the United States that is associated with the belief that disability is an undesirable status that needs to be cured...
In rapid serial visual presentation, identification of the second of two targets is impaired when it closely follows the first target. This attentional blink (AB) effect suggests limited capacity in processing successive visual stimuli in working memory. Awh et al. (2004) found that face identity Target 2 was immune to...
The SAVE project, a three arm randomized-controlled study, utilized evidence-based health and safety training to teach brick masonry apprentices ergonomics, problem solving, and communication skills to reduce occupational musculoskeletal injury risk.

Self-disclosure is a complex process that impacts social, cultural, and individual contexts of people’s lives. Under ideal circumstances, disclosure strengthens social bonds, enhances intimacy in relationships, and fosters a more unified sense of the self. Disclosing information about a stigmatized identity, however, is associated with a variety of risks and...
There are few modern isotopic ages of igneous rocks and polymetallic (Pb-Zn-Ag-Cu-Au) hydrothermal mineral veins of the Mt. Thompson quadrangle in southwestern Montana. Lithology ages of this region vary from approximately 85-80 Ma Butte granite(Kbg) (Lund et al. 2002) to 48.6 Ma of Lowland Creek Volcanic Field (LCVF) (Dudas et...
Consumption of raw dairy products has been linked to diseases such as Salmonella, Campylobacter, E. coli and Listeria. Current retail sale of raw milk in Oregon is limited to disease-free goat or sheep milk. Raw cow milk is legally for sale on farms with less than three cows. Consumers have...
Freezing to death in winter is a danger faced by ectothermic organisms throughout temperate climates. One adaptation of lepidopteran insects for overwinter survival is the sequestration of antifreeze solutes in the hemolymph prior to pupal diapause. This acts to depress freezing points during the long and immobile pupal stage during...
College students need accurate information to both prevent sexual assault and to access services following sexual assault. Effective communication serves an important public health role by reducing both assaults and psychological distress. In contrast, ineffective communication can both increase assaults and psychological distress. Little empirical research is available to guide...
The gas phase electron-diffraction (GED) technique has been the primary method used to expand our knowledge and understanding of gas-phase molecular structures. The technique yields interatomic distances and bond angles that are of use in both theoretical and experimental studies.
The GED structural parameters are thermal averages over all vibrational...
Ice core records provide us a way to investigate past climate and look in detail at past atmospheric conditions. With, on average, higher CO2 concentrations in the Greenland record, the focus of this project was on the potential mechanisms responsible for the higher CO2 concentrations in the Greenland ice core...
Cancer is a hard disease to control because of its ability to spread to different parts of the body. Cancer cells can spread out from a primary tumor to distant organs which gives rise to new cancer cell colonies and more tumors over time. This process is known as metastasis...
Dibenzo[def,p]chrysene (DBC) is a polycyclic aromatic hydrocarbon (PAH) and an IARC classified 2A probable human carcinogen. Mouse progeny transplacentally exposed to DBC have been shown to develop lung and liver tumors, with liver tumors developing predominantly in males later in life. Sulforaphane (SFN) is an isothiocyanate that plays a crucial...
After a joint injury, arthrogenic muscle inhibition (AMI) leads to decreased neuromuscular control and strength, as neural inhibition prevents volitional activation of the entire motor neuron pool. Traditional rehabilitation techniques such as strength training are unable to effectively reduce AMI and there is a need to identify interventions that can...
Traditional visual survey methods for marine mammals can only detect a fraction of the animals present. Even if the animal can be observed from the surface, visual limitations such as time of day and weather conditions can impede this ability. Recent advances in passive acoustic monitoring technologies have led to...
