At the University of Oregon, our students benefit from access to the widest possible range of newly published scholarly information through our Library’s subscriptions and e- resource collections. This access costs millions of dollars annually, much of it paid to the private, for- profit companies who collect and publish research. Many members of the public—including students at less well-funded institutions; high school students and K12 teachers; and curious learners unaffiliated with any university—lack the ability to read and learn from the latest scientific and medical information because the subscriptions are so unaffordable. This lack of access hinders scientific progress and is particularly unfair when considering that the public funds the underlying research activity through their tax dollars. The OSTP’s updated policy will ensure that when the government funds research—by providing grants to buy equipment, materials, hire researchers, run analyses, and more—that the findings from that research are immediately returned to the public for their benefit. We hope that this policy also means that the UO Library will be able to spend less every year on paying for these subscriptions, which will enable us to invest more directly in our students, faculty, and their important teaching and research work. We are proud to support the Oregon Undergraduate Research Journal as an open scholarly communications forum that undergraduates everywhere can read without cost. The UO and its Libraries will continue to advocate strongly for a fair and inclusive research communications system that everyone can afford to participate in.","PeriodicalId":338305,"journal":{"name":"Oregon Undergraduate Research Journal","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128687773","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous research suggests that a thiamine-deficient diet not only endangers infants’ health, but also hinders infants’ neuro-cognitive development. As part of a larger, randomized controlled trial, this thesis investigated possible benefits of maternal thiamine supplementation for protecting the neurological development of Cambodian infants who are breastfed. Lactating mothers were randomly assigned to four treatment groups (0, 1.2, 2.4, and 10mg daily thiamine supplement) when infants were between 2- and 24-weeks postnatal. Infants’ neurological function was measured at 2-, 12-, 24-, and 52-weeks via the Hammersmith Neurological Examination (Hammersmith), a field-standard clinical assessment tool. As expected, infants’ Hammersmith scores improved significantly with age. However, the data indicated that maternal thiamine supplementation dose had no effect on infants’ Hammersmith scores. This research indicates that the basic neurological functions, as assessed by the Hammersmith in early infancy were relatively unaffected by maternal thiamine supplementation.","PeriodicalId":338305,"journal":{"name":"Oregon Undergraduate Research Journal","volume":"159 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133385781","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study asks if and how P . polymerus individuals gain in overall fitness from gregarious settlement. The study addresses two questions: 1) Is the growth rate of early juveniles dependent on the velocity of the water in which they feed? and 2) Does settlement on conspecifics benefit early juveniles by increasing growth rate? Two treatment groups (solitary and gregarious) and an experimental velocity gradient were studied in marina and tank environments, with P . polymerus individuals ranging in size from 1 to 3 mm (measured by rostro- carinal length). For the trials carried out in a marina environment, growth rates ranged from 0.1 to 1.2 mm per week at any given velocity. For the trials in a tank environment, individual growth never exceeded 0.6 mm per week. Overall results indicate that neither current velocity nor settlement location had consistent effects on early juvenile growth rates. In the tank environment, where food concentrations were lower, velocity had a significant negative effect on the growth rate of gregarious but not solitary juveniles. Meanwhile, settlement on a conspecific had a significant positive effect on average juvenile growth in one of the four trials. The absence of consistent trends within and across trials indicates that velocity and settlement location for early juveniles may not be primary factors in gregarious settlement of this barnacle. The results also have important implications for aquaculture; they suggest that P. polymerus juveniles do not require specific flow speeds or adult substrata to cultivate newly-settled barnacles.","PeriodicalId":338305,"journal":{"name":"Oregon Undergraduate Research Journal","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114083680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When the phonetic quality of a hesitation sound is consistent with native speaker hesitation sounds, the hesitation sound is “native.” A hesitation sound with phonetic quality inconsistent with native speaker hesitation sounds is “nonnative.” In Experiments 1A and 1B, participants rated sentences for fluency and accentedness on a Likert scale. In Experiments 2A and 2B, listeners performed a forced choice task to evaluate speech for accentedness and fluency. In Experiments 1A and 1B, hesitation sound phonetic quality did not impact listeners ratings. However, in Experiments 2A and 2B, participants deemed sentences with nonnative hesitation sounds less fluent and more accented compared to those with native hesitation sounds. Results show that the hesitation sound phonetic quality can have perceptual consequences and that the type of task listeners performed to evaluate speech affected accentedness and fluency judgments. This study has important implications for how learners treat pausing when practicing their second language.","PeriodicalId":338305,"journal":{"name":"Oregon Undergraduate Research Journal","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126293349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper, though, looks at existing promising works surrounding the Anthropocene and argues that the dialogue lacks holistic conceptions of agency and spatial and temporal scale variance in order to fully grasp its complexity. Agency refers to the flawed understanding of the Anthropocene as simply human without consideration for other assemblages, which denotes the other stakeholders apart from humans. Temporal scale refers to the need for a varied consideration of time and the creation of assemblages. Spatial scale refers to the different levels of interaction (national, international, socioeconomic. This understanding of scales, or scale variance, relies on Derek Woods’ theory that multiple scalar levels are necessary to encapsulate the Anthropocene. This paper will approach scale variance by constructing the Anthropocene Commons model. The model, based its theoretical framework on Garrett Hardin’s Tragedy of the Commons on resource, will utilize the three levels of scale absent in other scholarship. The paper will examine other models used to address climate change and discuss their lack of the necessary scope and holistic framework and how their prescriptions for addressing climate catastrophe fall short. Using scale variance in the Anthropocene commons, then, will seek to correct it and offer a standardized but flexible framework to better address the ongoing and impending crisis.","PeriodicalId":338305,"journal":{"name":"Oregon Undergraduate Research Journal","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129100026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By 1960, they had been found to be non-addictive, to have remarkable safety profiles, and to potentially be able to treat a range of psychological conditions. However, in 1968, the possession of psychedelics was criminalized by the US federal government. Consequently, medical research has been stifled, and today the possession and distribution of psychedelics are punished more severely than for more dangerous recreational drugs such as methamphetamine. Most scholars argue that psychedelics were criminalized due to a “moral panic” in the late 1960s. However, this theory overlooks several important aspects of the political process that led to psychedelic criminalization. This essay takes an alternative stance. First, early 20th century temperance advocates instilled an anti-drug moral framework into the American cultural consciousness. Then, in the early 1960s, safety concerns and professional biases led most mainstream psychiatrists to reject the therapeutic use of psychedelics. These factors interacted to cause both a moral panic and severe criminalization, but the moral panic did not itself cause criminalization.","PeriodicalId":338305,"journal":{"name":"Oregon Undergraduate Research Journal","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129539457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
