The Development of a Situational Judgment Test to Assess Collegiate Judgment: A Pilot Study

Traditionally, colleges and universities have focused primarily on cognitive predictors (e.g., ACT/SAT scores, high school GPA), and have struggled to find an accurate and objective way of measuring non-cognitive skills, often resorting to personality measures or interviews, or deciding not to measure them at all. Recently, there has been a push for alternative forms of student selection that result in less adverse impact and do not ignore important skills and traits that are necessary to be successful in college (Peeters & Lievens, 2005; Atkinson, 2001). Growing evidence suggests Situational Judgment Tests (SJTs) may be one way to achieve this goal. SJTs are a type of psychological aptitude test in which respondents are presented with a short vignette/scenario about a particular situation, and are then asked to either rate the effectiveness of the responses (knowledge SJTs), or indicate what response the participant would choose if they were in that situation (behavioral tendency SJTs). The current study collected pilot data from undergraduate students at a large Midwestern university. Students answered several SJT items, a measure of the Big 5 (Goldberg’s Big 5 Markers), and a small number of demographic items, including students’ GPA and standardized test scores (ACT/SAT). Students’ responses on the SJT items were compared with the other data collected to determine if there was validity evidence for the use of SJTs in predicting college GPA. The results provide evidence that SJTs may be useful for admissions departments to aid in the selection of students or for student retention and development. Advisor: James A. Bovair

Game-theoretic Analysis of Effort Allocation of Contributors to Public Projects

Public projects can succeed or fail for many reasons such as the feasibility of the original goal and coordination among contributors. One major reason for failure is that insufficient work leaves the project partially completed. For certain types of projects anything short of full completion is a failure (e.g., feature request on software projects in GitHub). Therefore, project success relies heavily on individuals allocating sufficient effort. When there are multiple public projects, each contributor needs to make decisions to best allocate his/her limited effort (e.g., time) to projects while considering the effort allocation decisions of other strategic contributors and his/her parameterized utilities based on values and costs for the projects. In this paper, we introduce a game-theoretic effort allocation model of contributors to public projects for modeling effort allocation of strategic contributors. We study the related Nash equilibrium (NE) computational problems and provide NP-hardness results for the existence of NE and polynomial-time algorithms for finding NE in restricted settings. Finally, we investigate the inefficiency of NE measured by the price of anarchy and price of stability. [Includes Supplementary Material.

Cardiopulmonary Exercise Test Methodology for Assessing Exetion Intolerance in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome

Background: Concise methodological directions for administration of serial cardiopulmonary exercise testing (CPET) are needed for testing of patients with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS). Maximal CPET is used to evaluate the coordinated metabolic, muscular, respiratory and cardiac contributions to energy production in patients with ME/CFS. In this patient population, CPET also elicits a robust post-exertional symptom flare (termed, post-exertional malaise); a cardinal symptom of the disease. CPET measures are highly reliable and reproducible in both healthy and diseased populations. However, evidence to date indicates that ME/CFS patients are uniquely unable to reproduce CPET measures during a second test, despite giving maximal effort during both tests, due to the effects of PEM on energy production. Methodology: To document and assess functional impairment due to the effects of post-exertional malaise in ME/CFS, a 2-day CPET procedure (2-day CPET) has been used to first measure baseline functional capacity (CPET1) and provoke post-exertional malaise, then assess changes in CPET variables 24 h later with a second CPET to assess the effects of post-exertional malaise on functional capacity. The second CPET measures changes in energy production and physiological function, objectively documenting the effects of post-exertional malaise. Use of CPET as a standardized stressor to induce post-exertional malaise and quantify impairment associated with post-exertional malaise has been employed to examine ME/CFS pathology in several studies. This article discusses the results of those studies, as well as the standardized techniques and procedures for use of the 2-day CPET in ME/CFS patients, and potentially other fatiguing illnesses. Conclusions: Basic concepts of CPET are summarized, and special considerations for performing CPET on ME/CFS patients are detailed to ensure a valid outcome. The 2-day CPET methodology is outlined, and the utility of the procedure is discussed for assessment of functional capacity and exertion intolerance in ME/CFS

Improvement of individual camouflage through background choice in ground-nesting birds.

Animal camouflage is a longstanding example of adaptation. Much research has tested how camouflage prevents detection and recognition, largely focusing on changes to an animal's own appearance over evolution. However, animals could also substantially alter their camouflage by behaviourally choosing appropriate substrates. Recent studies suggest that individuals from several animal taxa could select backgrounds or positions to improve concealment. Here, we test whether individual wild animals choose backgrounds in complex environments, and whether this improves camouflage against predator vision. We studied nest site selection by nine species of ground-nesting birds (nightjars, plovers and coursers) in Zambia, and used image analysis and vision modeling to quantify egg and plumage camouflage to predator vision. Individual birds chose backgrounds that enhanced their camouflage, being better matched to their chosen backgrounds than to other potential backgrounds with respect to multiple aspects of camouflage. This occurred at all three spatial scales tested (a few cm and five meters from the nest, and compared to other sites chosen by conspecifics), and was the case for the eggs of all bird groups studied, and for adult nightjar plumage. Thus, individual wild animals improve their camouflage through active background choice, with choices highly refined across multiple spatial scales

Evaluating PSU\u27s Community Forests: Langdon Woods and Fox Park

Langdon Woods and Fox Park are two community forests located on the Plymouth State University campus which provide numerous ecosystem services for students and residents. The goal of this project is to evaluate these services and propose future courses of action which will improve and protect these areas. We are also working with the ES&P Seminar class to achieve Tree Campus USA status for PSU. Langdon Woods borders the Baker River and is located on its floodplain. This area has walking and biking trails and is used by a variety of PSU’s ES&P and Adventure Education classes. We will examine the possibility of putting Langdon Woods into a conservation easement. We will also work with Angel Ekstrom, who has proposed a cluster project to further develop mountain biking trails in Langdon Woods and Fox Park. Our group will utilize both iTree canopy and iTree design to get an idea of the tree species composition, canopy cover, potential economic value, etc. Also, we will work in GIS to develop analyze these areas and produce maps. We have access to the wildlife management plan and will use this to evaluate the animal species present and their conservation status

The Truth About Honesty: An Interdisciplinary Analysis of the Trait of Honesty

In both the psychological and philosophical literature, there is little time devoted to a robust understanding of the character trait of honesty. The trait of honesty is often used as an example of a beneficial or good character trait, yet the gap in the literature raises a vexing question: what is honesty? This poster reports ongoing work aimed at identifying folk theories of honesty. We argue that an understanding of these theories can illuminate a principled understanding of this character trait in both psychology and philosophy. Currently, we are using qualitative surveys to develop an operational definition of honesty. This will allow us to develop a quantitative measure in order to assess the strength of the trait in particular individuals. The quantitative data will be used to classify and categorize the trait of honesty within the Five Factor Model of personality and to generalize the construct of virtuous traits within virtue ethics in philosophy. If honesty is shown to be distinct from existing categories of traits in psychology or if its characteristics are shown to be incompatible with situationist ethics in philosophy, then we will formulate a new research program in order to better understand the relationship between the trait of honesty and each theory. This poster sketches some approaches to these possible outcomes that we find plausible

Differential Impact of Biological and Behavioral Traits on Postexercise Energy Intake in Men andWomen

The energy intake response to exercise is highly variable and energy (over-) compensation via increased post-exercise energy intake occurs in some individuals but not others. In explorative analyses, we aimed to identify biological and behavioral predictors of post-exercise ad libitum energy intake and whether these predictors differ from ad libitum energy intake after rest. Conclusions:Post-exercise energy intake is associatedwithdifferent factors than energy intake after rest and behavioral and biological traits differentially affect post-exercise energy intake in men and women. In women, habitual exercise behavior seems to predict postexercise energy intake, protecting against compensatory eating. Inmen, appetite-regulating hormones play a role in the energy intake response to acute exercise. Our findings may help identify individuals who are likely to show post-exercise energy compensation and help explain why it occurs in some individuals but not others

Novel functional view of the crocidolite asbestos-treated A549 human lung epithelial transcriptome reveals an intricate network of pathways with opposing functions

<p>Abstract</p> <p>Background</p> <p>Although exposure to asbestos is now regulated, patients continue to be diagnosed with mesothelioma, asbestosis, fibrosis and lung carcinoma because of the long latent period between exposure and clinical disease. Asbestosis is observed in approximately 200,000 patients annually and asbestos-related deaths are estimated at 4,000 annually<abbrgrp><abbr bid="B1">1</abbr></abbrgrp>. Although advances have been made using single gene/gene product or pathway studies, the complexity of the response to asbestos and the many unanswered questions suggested the need for a systems biology approach. The objective of this study was to generate a comprehensive view of the transcriptional changes induced by crocidolite asbestos in A549 human lung epithelial cells.</p> <p>Results</p> <p>A statistically robust, comprehensive data set documenting the crocidolite-induced changes in the A549 transcriptome was collected. A systems biology approach involving global observations from gene ontological analyses coupled with functional network analyses was used to explore the effects of crocidolite in the context of known molecular interactions. The analyses uniquely document a transcriptome with function-based networks in cell death, cancer, cell cycle, cellular growth, proliferation, and gene expression. These functional modules show signs of a complex interplay between signaling pathways consisting of both novel and previously described asbestos-related genes/gene products. These networks allowed for the identification of novel, putative crocidolite-related genes, leading to several new hypotheses regarding genes that are important for the asbestos response. The global analysis revealed a transcriptome that bears signatures of both apoptosis/cell death and cell survival/proliferation.</p> <p>Conclusion</p> <p>Our analyses demonstrate the power of combining a statistically robust, comprehensive dataset and a functional network genomics approach to 1) identify and explore relationships between genes of known importance 2) identify novel candidate genes, and 3) observe the complex interplay between genes/gene products that function in seemingly different processes. This study represents the first function-based global approach toward understanding the response of human lung epithelial cells to the carcinogen crocidolite. Importantly, our investigation paints a much broader landscape for the crocidolite response than was previously appreciated and reveals novel paths to study. Our graphical representations of the function-based global network will be a valuable resource to model new research findings.</p
