Aspen As Firebreaks At The Development Fringe, Kevin Krasnow, Paul C. Rogers

Aspen Bibliography

Quaking aspen (Populus tremuloides) forests are widely known and prized for their numerous values—biodiversity, habitat, forage, recreation, aesthetics, and others—including as a deterrent to wildfire. This reputation for stopping or slowing flames is explored here, alongside measures that may be taken to facilitate thriving aspen communities near human developments. It is clear that science supporting the premise of aspen as an effective firebreak is far from complete. Yet, how can we benefit from what we do know on this topic to increase the probability of preventing structural fire damage, while also encouraging the valued characteristics of aspen ecosystems?

Climate Considerations For Quaking Aspen Conservation, Douglas Shinneman, Susan Mcilroy, Paul C. Rogers

Aspen Bibliography

Human-caused climate change alters ecosystem processes ranging from local to global scales. As a consequence of climate change we should expect increased rates and intensities of disturbance events. Though we are only beginning to understand what those impacts might be to aspen forests and their diverse plant and animal assemblages, recent science suggests there may be unavoidable effects. In the face of anticipated climate-ecosystem challenges, contemporary managers are searching for guidance on preserving aspen resilience. We suggest crafting strategic yet cautious approaches to minimize effects and facilitate broad resilience. For instance, monitoring conditions in and near aspen forests will help …

Investigating The Relationship Between Malingering And Institutional Misconduct: Is Psychopathy The Link?, Lily A. Reed

Student Theses

Despite the established relationships between psychopathy and malingering, and psychopathy and risk for institutional misconduct, little empirical literature has been devoted to examining the interaction of these three constructs. The current study aimed to clarify this relationship by examining data from a sample of male criminal defendants within a federal prison located in a metropolitan area of the Southern United States. Data including the MMPI-2, PCL-R, diagnostic, institutional records, and demographic information was collected. Statistical analyses reinforced previous literature and theoretical conceptualizations that posit a relationship between psychopathy and malingering behaviors, as well as institutional misconduct. Preliminary findings suggest links …

Short-Term Response Of Soil Microbial Community And Soil Bio-Chemical Properties To Soybean Intercropping In A Cassava-Based Cropping System, Nolissa Organo, John Lester Pide, Michelle Anne Calubaquib, Elmer Enicola, Evelyn Delfin, Vanessa Calderon, Raymund Antiola, Hosne Dilzahan, Andre Cruz

The Philippine Agricultural Scientist

A cassava-based cropping system study assessed the short-term response of soil chemical and biochemical properties and soil microbial communities to soybean intercropping. Two soybean varieties (‘Select Manchuria’ and ‘Tiwala 12’) were tested as intercrops. The treatments did not affect the soil’s chemical (pH, OM, N, P, K) and biochemical (basal respiration and dehydrogenase and urease enzyme activities) properties after one cropping period. Amplicon sequencing analysis found that intercropping promoted the abundance of bacterial orders Actinomycetales, Solibacterales, Sphingomonadales, and Rhodospirillales. These groups play active roles in organic matter decomposition and can potentially improve the soil quality in an area by enhancing …

Interpretable Learning In Multivariate Big Data Analysis For Network Monitoring, José Camacho, Katarzyna Wasielewska, Rasmus Bro, David Kotz

Dartmouth Scholarship

There is an increasing interest in the development of new data-driven models useful to assess the performance of communication networks. For many applications, like network monitoring and troubleshooting, a data model is of little use if it cannot be interpreted by a human operator. In this paper, we present an extension of the Multivariate Big Data Analysis (MBDA) methodology, a recently proposed interpretable data analysis tool. In this extension, we propose a solution to the automatic derivation of features, a cornerstone step for the application of MBDA when the amount of data is massive. The resulting network monitoring approach allows …

Population-Level Immunologic Variation In Wild Threespine Stickleback (Gasterosteus Aculeatus), Anika M. Wohlleben, Javier F. Tabima, Néva P. Meyer, Natalie C. Steinel

Biology

Wild organisms are regularly exposed to a wide range of parasites, requiring the management of an effective immune response while avoiding immunopathology. Currently, our knowledge of immunoparasitology primarily derives from controlled laboratory studies, neglecting the genetic and environmental diversity that contribute to immune phenotypes observed in wild populations. To gain insight into the immunologic variability in natural settings, we examined differences in immune gene expression of two Alaskan stickleback (Gasterosteus aculeatus) populations with varying susceptibility to infection by the cestode Schistocephalus solidus. Between these two populations, we found distinct immune gene expression patterns at the population level in response to …

Comprehensive Examination Of The Effect Of A Randomized Controlled Brief Mindfulness-Based Intervention On Autonomic Nervous System Functioning, Li Shen Chong

Legacy Theses & Dissertations (2009 - 2024)

Brief mindfulness-based interventions are comparable to traditional mindfulness-based interventions in alleviating stress and improving well-being. To explore the underlying biological mechanisms of these practices, researchers have been exploring the effects of mindfulness-based interventions through the autonomic nervous system (ANS), a major bodily stress response system. Nevertheless, most of these studies relied on one stress response system or a specific biomarker. This study aims to comprehensively examine the effectiveness of two sessions of brief mindfulness-based interventions on ANS functioning. Participants were assigned to the brief mindfulness intervention condition (n = 44) or control condition (n = 47). Participants’ physiological data, including …

Tango2 Deficiency Disease Is Predominantly Caused By A Lipid Imbalance, Michael Sacher, Jay Deloriea, Mahsa Mehranfar, Cody Casey, Aaliya Naaz, Samuel J. Mackenzie, Chiara Gamberi

Biology

TANGO2 deficiency disease (TDD) is a rare genetic disorder estimated to affect ∼8000 individuals worldwide. It causes neurodegeneration often accompanied by potentially lethal metabolic crises that are triggered by diet or illness. Recent work has demonstrated distinct lipid imbalances in multiple model systems either depleted for or devoid of the TANGO2 protein, including human cells, fruit flies and zebrafish. Importantly, vitamin B5 supplementation has been shown to rescue TANGO2 deficiency-associated defects in flies and human cells. The notion that vitamin B5 is needed for synthesis of the lipid precursor coenzyme A (CoA) corroborates the hypothesis that key aspects of TDD …

What Does It Mean To Be Kindergarten "Ready?": Trends In Parents' Expectations And Families' School Experiences Across Ses, Lisa Babel

Dissertations, Theses, and Capstone Projects

The purpose of this study is to explore the meaning of Kindergarten “ready,” especially as the practice interacts with educational inequity. Past research used secondary data to show that SES relates to the prevalence of redshirting where children’s school entry is delayed by one year with the idea that the older they are when they start school, the more advanced they will be, but studies do not explain why children from families with lower incomes are advised to start Kindergarten later than others (Greensburg & Winsler, 2020; Reardon & Portilla, 2016). Moreover, family expectations of the Kindergarten participation process, including …

Fragmentation And Some Applications, Joseph Bendana

Dissertations, Theses, and Capstone Projects

This dissertation is an exploration of the idea that human minds are fragmented and its implications for some ongoing debates in the philosophy of mind and epistemology. Let Fragmentation be, minimally, the view that human cognitive information access is best modeled as having a structure that permits for selective, variable-mediated access, instead of a structure that enables always-on, global access. In chapter 1, I canvass the motivation for this view, its many variants, and some of the key open questions that it raises, situating this project in the broader landscape of work on the view. In chapter 2 I argue …

Math Anxiety And Avoidance Of Mathematics At The College Level: Undergraduate And Their Sense Of Not Belonging In Math Classrooms, Kay C. Lashley

Dissertations, Theses, and Capstone Projects

Negative experiences and perceptions of the subject often influence the avoidance of mathematics at the college level. This study explored this issue by investigating the relationship between math anxiety, belongingness in math classes, and help-seeking behaviors among STEM and non-STEM majors. The study involved 41 participants, including 24 STEM majors and 17 non-STEM majors, all undergraduate college students aged 18 to 54. The results revealed that most students (39 out of 41) felt a sense of belonging in their math classes. Correlation analyses showed a significant positive relation between math anxiety and self-reported math competency, “r(41)= .44, p < .01,” and that higher levels of math anxiety were linked to a greater likelihood of avoiding math classes, “r(41)= .35, p = .02”. Students with lower math anxiety were marginally more inclined to seek help from family or friends, “ X2 (12, N = 42) = 20.1, p = .065”. However, there were no significant differences in help-seeking behaviors between STEM and non-STEM majors. Overall, these findings are consistent with previous studies. Nevertheless, more research and interventions are needed to develop supportive math learning environments at the college level, especially for students with higher anxiety.

Socially Racialized And Statistically Invisible: U.S. Census Recognition Of The Middle Eastern And North African Diaspora, Aliana J. Jabbary

Dissertations, Theses, and Capstone Projects

This thesis delves into the recent decision by the U.S. Executive’s Office of Management and Budget (OMB) to revise the statistical categorization of Middle Eastern and North African (MENA) individuals within federal statistical collection, particularly focusing on the U.S. Decennial Census’ racial and ethnic classifications as outlined in the OMB’s Statistical Policy Directive no. 15. Historically classified solely as racially White, the MENA diaspora’s statistical invisibility within federal data has significant impacts on policy eligibility and access to legal protections, contributing to their social erasure from the national identity. Through a comprehensive analysis of racialization and Orientalism scholarship, alongside an …

Evolution Of The Extant And Fossil Colobinae (Primates, Cercopithecidae), Julia L. Arenson

Dissertations, Theses, and Capstone Projects

The Colobinae (leaf-eating monkeys) are one of two crown cercopithecoid subfamilies along with the Cercopithecinae (cheek-pouch monkeys). They are today represented by a diverse modern radiation comprising two reciprocally monophyletic geographic subtribes, the African Colobina and the Asian Presbytina, which are collectively united by shared adaptations to folivory and arboreality. In addition, the colobine fossil record documents a taxonomically and ecologically diverse, geographically widespread radiation from the late Middle Miocene onwards. Fossil colobines exhibit an array of body sizes, craniofacial morphologies, postcranial adaptations, and dental dietary signals that exceeds those of the modern radiation and are also widespread over Africa, …

The Cultural Complexity Of Immigrants And The Implications For Personality Assessment: Exploring The Role Of Frame Switching, Patrick Jay Lee

Dissertations, Theses, and Capstone Projects

A significant body of personality research has focused on cross-national comparison, but less attention has been devoted to within-country subcultural complexity – especially with regards to the growing population of bicultural immigrants who subscribe to multiple cultural-value systems. Bicultural individuals have been found to view situations under distinct frames of reference corresponding to their heritage and host cultures, and their attitudes and behavior can vary depending on which frame is activated at a given moment. This dissertation investigates whether such frame switching effects can be caused by elements within a formal personality assessment setting, and in turn affect bicultural respondents’ …

Cross-Linguistic Differences In Neural Encoding And Processing Of Stop Consonants: The Impact Of Language Experience On Attention Allocation, Aline Dos Santos Oliveira

Dissertations, Theses, and Capstone Projects

This study aims to examine the intricate relationship between language experience and the neural processing of stop consonant speech sounds. Previous research has shown minimal differences in amplitudes and latencies of cortical Auditory Evoked Potentials (AEPs) to speech sounds across listeners from various language backgrounds. It is only towards the later latencies (around the P2 peak at 200 ms), that there have been suggestions of cross-linguistic differences. In addition, a recent study, observed an AEP difference between monolinguals and bilinguals when processing speech, specifically an "Nd effect”. The Nd effect, which is an increased negativity of the AEP is proposed …
