Pettit Lake: A New Treasure for Silverton

70 pagesThis report includes student work from the LA 489/589 Advanced Design Studio in fall term of 2019. This work was executed by landscape architecture students in collaboration with the city of Silverton with the goal of presenting cohesive designs for the Pettit Lake property as a public park and possible income-generating resource for the City. Site analyses of geology, hydrology, landslide risk assessment, existing park assets, soils, sunlight, acoustics, and historical vegetation are included, as well as background research on the city of Silverton; The Oregon Garden, which abuts the site; and Don Pettit, the former resident of the site. Students working in small groups developed three combined plans as well as eight individual designs. Student final projects, focusing on design goals and objectives for the site, include passive day-use parks, naturalistic campgrounds, hiking trails, funiculars, and wildlife interpretation centers. Various potential design layouts and programmatic combinations are included in this report in response to the city of Silverton’s program matrix elements. Eight distinct designs were produced, which were combined into three plans. Of key importance for Silverton community members were the retention of the site’s natural character and calm, secluded quality, while still allowing public enjoyment of the landscape. Students incorporated these objectives into their final designs

Impact of stressing a pen mate on physiological responses of growing pigs

Crossbred barrows and gilts (n = 36), weighing 16.59 ± 2.1 kg, were used to test the effects of stressing a pen mate on the physiological responses of growing pigs. Pigs were randomly allotted to 6 groups after stratifying according to gender, litter origin, and body weight. Dominance order was determined within each group, and 1 to 3 d prior to the stress treatment the most- and leastdominant pigs within a group were fitted with indwelling catheters in their vena cavas. Over 3 d, groups were either: 1) isolated from audile and visual contact with stressed pigs in a separate room (non-stressed control); 2) separated by a curtain from visual contact with stressed pigs; or 3) allowed to maintain audile and visual contact with stressed pigs. Blood samples were collected 30, 15, and 0 min before exposure to the stressor (snout-snare) treatment and again at 1, 2, 3, 4, 5, 7.5, 10, 15, 20, 25, and 30 min after stressor application. Serum cortisol and plasma glucose, lactate, and nonesterified fatty acids (NEFA) concentrations were measured. There were no treatment × sampling-time interactions (P \u3e 0.17) for concentrations of cortisol, glucose, lactate or NEFA, nor were these metabolites affected by stressor treatment (P \u3e 0.42). Humoral measures of the stress response were not affected by visual and/or audile contact with pen mates undergoing a stressful event

Advancing Methodology: From Mapping to Mobile Messaging Campaign

This article describes the progression of the Health Insurance Literacy (HIL) Action Team’s efforts from the initial charge by the Extension Committee on Organization and Policy (ECOP) of identifying priorities for Cooperative Extension health programming to developing and testing a national mobile messaging campaign designed to change health insurance knowledge, confidence, and behaviors of millennials. It highlights relevant empirical literature, summarizes the results of a national pulse online survey administered to Extension professionals and how they were applied to this project, reviews the Design Thinking and concept mapping process, and describes the development and testing of mobile messages. Anticipated outcomes of the mobile messaging campaign are discussed. Sources of data are the national pulse online survey along with insights gleaned from Extension professionals who participated in workshops, an eXtension Design-a-thon, and responses to a survey of millennials about experiences using health insurance, social media, and texting. This effort contributes to advancing Extension’s capacity to deliver programming related to health insurance education in innovative and effective ways

Sex-dependent associations between maternal prenatal cortisol and child callous-unemotional traits: findings from the Wirral Child Health and Development Study

Elevated maternal glucocorticoids during pregnancy may impact on fetal development in a sex-dependent way, leading to increased amygdala activation and increased risk for internalising disorders in females. Based on evidence implicating reduced amygdala activation in callous-unemotional (CU) traits, we predicted that elevated maternal cortisol in pregnancy would be associated with lower CU traits and elevated anxious-depressed symptoms, only in girls. Participants were 225 members of a stratified subsample within an epidemiological longitudinal cohort (WCHADS). Salivary cortisol was measured over two days at 32 weeks gestation (on waking, 30-min post-waking and during the evening) and the log of the area under the curve (LogAUC) was calculated as an index of diurnal cortisol. Mothers reported on child CU traits and anxious-depressed symptoms at 2.5, 3.5 and 5.0 years of age. As predicted there was a sex of child by cortisol interaction (p < .001) whereby elevated maternal cortisol was associated with lower child CU traits, explaining 25% of the variance, in girls, but not in boys. This effect remained when controlling for relevant confounders and anxious-depressed symptoms. By contrast, elevated maternal cortisol did not predict higher anxious-depressed symptoms in girls. The study adds to growing evidence for sex-dependent effects of elevated maternal cortisol during pregnancy on early child psychopathology, consistent with mediation by elevated amygdala activation. The conditions under which, in girls, this is associated with heightened responsiveness to others' distress characteristic of low CU traits, or with increased affective symptoms, require further study

The Grass Remembers the Horses: A land management design approach to incorporating free-roaming American mustangs (Equus caballus) on Western rangelands

64 pages. Committee chair: Kory RusselThe United States currently faces a range crisis on it’s public lands. Federally protected mustangs (Equus caballus) share a degraded range with millions of grazing livestock. Mustangs’ contentious status as an alleged invasive species is at odds with their protective status. Not managed as wildlife yet not classified as livestock, mustangs are removed from the range in the thousands only to live out their lives in costly government holding facilities which eat up most of the Bureau of Land Management’s wild horse and burro budget. The BLM faces heavy opposition to mustangs from ranchers and political lobbyists. The entire public rangeland situation is a tangled web of public outcry, bureaucratic mismanagement, and dueling interests. This project seeks to untangle the issues within the rangeland crisis through a “Land Management Design” approach. It presents a thorough background in the natural, cultural, and ecological history of the wild horse in North America, and focuses on the current management approaches utilized in the United States. Through the lens of several precedent studies, a strategic management framework is proposed. This framework is then applied to three Herd Management Areas (HMAs) in the state of Oregon. These three case studies are explored in depth and drone photography and mapping show the current status of these sites. Photoshop renderings present alternatives for how the sites could evolve when the proposed strategic management framework is applied. It is possible for all parties with stake in the rangeland crisis to benefit from a land management design approach. The conclusion of the project discusses this at length, and further delves into the sociopolitical changes that must take place for our public lands and our wild horses to be saved

An Exploratory Study of Integrative Personality Pathology Systems and the Interpersonal Circumplex

Normative and pathological personality traits are theoretically associated with interpersonal behavior patterns and difficulties. However, little is known about relations between dimensional personality systems that integrate pathological and normative traits and social functioning. The current study explores the projections of scales from two integrative frameworks, the Dimensional Assessment of Personality Pathology and the Schedule for Nonadaptive and Adaptive Personality, onto interpersonal circumplex traits and problems. The DAPP and the SNAP demonstrated similar overall validity in predicting the interpersonal domain. Results suggest a novel framework for understanding personality—interpersonal behavior relations by categorizing scales according to their: a) minimal, b) non-specific, c) specific, and d) differential relations to interpersonal traits and problems with important implications for future research relating clinical constructs to interpersonal behavior as well as clinical assessment and behavioral predictions based on SNAP and DAPP scales

Psychometric characteristics of the Inventory of Interpersonal Problems-Short Circumplex (IIP-SC) with college students

The Inventory of Interpersonal Problems-Circumplex (IIP-C; Alden, Wiggins, & Pincus, 1990) is a commonly used measure, and the Short Circumplex Version (IIP-SC; Soldz, Budman, Demby, & Merry, 1995) provides a potentially valuable and economical method for personality assessment researchers. However, despite the common use of the IIP-C with college students, the psychometric characteristics of the IIP-SC have not been established in a college student sample. This study provides reliability, structural validity, concurrent validity, and descriptive data for the IIP-SC in two samples of undergraduate students
