Ambivalence, Foremourning, And Displacement In The German Translation Of Marie Bonaparte's Topsy, Kooper Wilson Jun 2026

Ambivalence, Foremourning, And Displacement In The German Translation Of Marie Bonaparte's Topsy, Kooper Wilson

University Honors Theses

This paper offers a reading of Sigmund Freud’s German translation of Marie Bonaparte’s book, Topsy: The Golden-Haired Chow, in which the author attempts to both delay the death of her dog and mourn it in advance through what I call foremourning. I argue that the manifest subject matter of Topsy should not be interpreted away as a projection of merely human concerns, but rather that close attention to Freud’s translation introduces themes from his analytic experience which engender an appreciation of Topsy’s atopia (intractability). I draw from recent psychoanalytic theory, literary criticism, and deconstruction, especially Jacques Derrida’s seminars …


Urban Beavers At The Crossroads: How Ecological Knowledge, Sociodemographic, And Spatial Context Shape Public Perception And Coexistence Preferences, Matthew Guziejka Mar 2025

Urban Beavers At The Crossroads: How Ecological Knowledge, Sociodemographic, And Spatial Context Shape Public Perception And Coexistence Preferences, Matthew Guziejka

Dissertations and Theses

Urban beavers demonstrate synurbization by adapting to urban environments, offering ecological benefits such as biodiversity enhancement and flood mitigation, while also occasionally conflicting with infrastructure. This study examines how ecological knowledge, sociodemographics, and spatial context influence public perceptions and management preferences for urban beavers in the Tualatin River watershed, Oregon.

A voluntary survey of 176 participants from peri-urban areas assessed demographic characteristics, ecological knowledge, and attitudes toward management approaches. Spatial factors, such as proximity to watercourses and green spaces, were also analyzed. Logistic regression analyses were used to explore relationships between these factors and management preferences. Political orientation was significantly …


Impacts Of Human Disturbances On Alaskan Brown Bears (Ursus Arctos): A Literature Review, Stephanie J. Menjivar Jun 2023

Impacts Of Human Disturbances On Alaskan Brown Bears (Ursus Arctos): A Literature Review, Stephanie J. Menjivar

University Honors Theses

This thematic literature review presents a comprehensive analysis of the existing research on the various human disturbances that impact Alaskan brown bears (Ursus arctos). It explores key findings, trends, and gaps in the literature, focusing on the overarching themes of Land-Use Overlap, Hunting and Poaching, Noise Pollution, and Industrial Development. By synthesizing and critically evaluating a wide range of studies, this review aims to deepen our understanding of the common sources of disturbances and their implications on the spatial, feeding, and social behaviors of brown bears. A brown bear's response to human activities varies …


Predicting Parturition In A Long-Gestating Species: Behavioral And Hormonal Indicators In The Asian Elephant (Elephas Maximus), Heather Kelly Velonis Jun 2017

Predicting Parturition In A Long-Gestating Species: Behavioral And Hormonal Indicators In The Asian Elephant (Elephas Maximus), Heather Kelly Velonis

Dissertations and Theses

Captive populations of Asian elephants (Elephas maximus) in North America are not self-sustaining, and increasing reproductive success within captive populations is a high priority. The ability to accurately predict parturition can have a direct impact on elephant welfare. Elephants in captivity often require significant preparation and management throughout the birthing process, and complications during labor and delivery can necessitate immediate intervention, including stillbirth, protracted labor, maternal aggression towards a newborn calf, and dystocia. Being able to predict when parturition will commence can ensure appropriate staff is available and adequate monitoring is performed. Routine endocrine sampling can be used …


Being Human: How Four Animals Forever Changed The Way We Live, What We Believe, And Who We Think We Are, Jocelyn Mary Brady Jan 2014

Being Human: How Four Animals Forever Changed The Way We Live, What We Believe, And Who We Think We Are, Jocelyn Mary Brady

Dissertations and Theses

Our lives would not be what they are today without animals. From the food we eat, to the clothes we wear, animals provide tangible evidence of their importance every day. But more than that, animals have shaped who we are and what we believe. Often in ways we don't see.

That's what inspired me to write Being Human. This work began as an examination of how humans have altered animals to better match our imaginations and ideals, and too, the way these animals have irrecoverably altered how we live and look at the world. Consider, for example, that before they …


Ecology Of White-Cheeked Crested Gibbons In Laos, Julia Cleverly Ruppell May 2013

Ecology Of White-Cheeked Crested Gibbons In Laos, Julia Cleverly Ruppell

Dissertations and Theses

The endangered white-cheeked crested gibbon (Nomascus leucogenys), native to Laos, Vietnam, and perhaps China, remains little known and highly threatened. I studied seasonal variation in the diet, activity budget, and ranging behavior of three groups of white-cheeked crested gibbons in Nam Kading National Protected Area, Bolikhamxay Province, Laos, over 12 months in wet seasonal evergreen forest. Crested gibbons (Nomascus spp.) are speculated to be more folivorous than other gibbons, but this has never been confirmed because of the paucity of fieldwork on the genus. I studied diet in relation to forest seasonality to determine the contribution …

The domestic dog offers a unique opportunity to study complex disorders similar to those seen in humans, but within the context of the much simpler genetic backgrounds of pure breeds, which represent closed populations. We performed a whole-genome search for genetic risk factors of adult-onset deafness in the Border Collie, a breed of herding dog that relies on acute hearing to perceive and respond to commands while working. Adult-onset deafness in Border Collies typically begins in early adulthood and is similar to age-related hearing loss in humans. This earlier onset has particular impact on the utility of working Border Collies …


Humane Education: The Effects Of Animals In The Classroom On Children's Empathy In Japanese Elementary Schools, Mika Maruyama May 2005

Humane Education: The Effects Of Animals In The Classroom On Children's Empathy In Japanese Elementary Schools, Mika Maruyama

Dissertations and Theses

Although humane education, promoting children's kindness toward animals, has been evaluated as a factor influencing children's kindness toward humans later in their life, the effect of a classroom pet hasn't been well studied. The current study investigated the influence of intensified daily interactions with living animals in the classroom on the development of empathy among Japanese children. Specifically, the study examined (a) the effect of introducing animals into the classroom on children's empathic behaviors and attitudes, and (b) the generalization of this animal-directed empathy to humans.


Social Behavior In A Group Of Captive Bobcats : A Study In The Sociability Of Felids, Lon W. House Jan 1978

Social Behavior In A Group Of Captive Bobcats : A Study In The Sociability Of Felids, Lon W. House

Dissertations and Theses

A group of four captive bobcats (Felis rufus), two males and two females, was observed for 102.67 hours over the period of one year. A pilot study was conducted consisting of a minimum of three separate observations for each daylight hour. The remaining observations were concentrated during the early morning hours immediately after feeding, the time of maximum activity and social interaction.
