Emotions In The Classroom, Elizabeth D. Burris

Theses, Dissertations, and Projects

This study explores the classroom emotional experience of five teachers. It is based on the assumptions that teaching is an emotional enterprise; that teaching necessarily involves "emotional labor," or the work of emotion management; that attending to and working through emotions (a form of emotion management) can influence how teachers teach; and that doing this emotional labor in a group setting can be useful to teachers. An additional assumption is that psychoanalytic concepts can help frame teachers' emotional experiences. The study looks specifically at how teachers' awareness and understanding of emotions affect their experience of teaching and what it is …

Results

This work introduces a freely downloadable, software package, SBML-SAT, which implements algorithms for simulation, steady state analysis, robustness analysis and local and global sensitivity analysis for SBML models. This software tool extends current capabilities through its execution of global sensitivity …

Identifying And Characterizing Arabidopsis Jasmonate Signaling Components Manipulated By Pseudomonas Syringae, Neva Laurie-Berry

Arts & Sciences Graduate Student Theses and Dissertations

Jasmonate signaling is critical for susceptibility of Arabidopsis thaliana to the bacterial pathogen Pseudomonas syringae, as demonstrated by the reduced susceptibility of coil mutant plants. The infection responses of another jasmonate-insensitive mutant, jinl, had previously been unknown. This work demonstrates that susceptibility to P. syringae requires activity of the transcription factor JTN1/MYC2. Reduced susceptibility correlates with reduced sensitivity to the P. syringae phytotoxin coronatine, a molecular mimic of the endogenous jasmonate JA-Ile. The reduced susceptibility of jinl mutant plants correlates with increased salicylic acid (SA)-dependent signaling. Analysis of jinl plants carrying the sidl mutation, resulting in decreased S A synthesis …

Today’S Students – Tomorrow’S Engineers: Jump-Starting The Transition From University To Industry , David Klumpar

Small Satellite Conference

Evidence suggests that the nationwide production of Science Technology, Engineering, and Mathematics graduates qualified for employment in the aerospace enterprise is insufficient to meet current and future demand. A unique program at the Space Science and Engineering Laboratory (SSEL) at Montana State University (MSU) has been training a new generation of engineers and scientists through direct hands-on immersion in small satellite design and development. This program jump-starts the college to workplace transition by intimately involving undergraduate (and graduate) students in the hands-on design, development, test, and flight and operations of space flight systems. The extracurricular program is based upon the …

Norwegian Student Satellite Program - Ansat, Torbjørn Houge, Aleksander Marthinussen, Jøran Antonsen

Small Satellite Conference

This paper deals with the Norwegian Student Satellite Program (ANSAT), and will give a brief account of NCUBE and a description of the subsequent program. In 2002, four educational institutions started to work on a joint project of developing the first Norwegian student satellite. The project was expanded to include two almost identical satellites with launch-opportunities together with other pico satellites. In 2006, The Norwegian Center for Space-related Education (NAROM), Andøya Rocket Range (ARR) and the Norwegian Space Centre (NSC) decided to initiate a Norwegian Student Satellite Program as a subsequent program to the NCUBE projects with the development and …

Initial Development Of Embedded Low-Power Parallel Processing For On-Orbit Spacecraft Anomaly Management, Christopher Kitts, Paul Toledo, Mike Rasay

Small Satellite Conference

Maintaining the health of a spacecraft is a critical element of satellite operations, typically driving operations costs and often requiring standing armies of highly trained operations staff. An important aspect of this work is anomaly management (AM), which is the detection, diagnosis and resolution of anomalous conditions. Research in this area ranges from the development of robust reasoning techniques to the design of highly-performance flight processors able to implement these techniques on-orbit. Our recent work in this area focuses on the composition of advanced model-based reasoning (MBR) algorithms for AM that can be efficiently executed on a new generation of …

Wyeth V. Levine: Brief Of Amicus Curiae Constitutional And Administrative Law Scholars In Support Of Respondent, Nina A. Mendelson

Appellate Briefs

Amici are scholars who teach and write about federal preemption of state law. Mindful of the gap that sometimes exists between the academy and the concerns of the bench and bar, we seek to bring our scholarship to bear on the particular preemption questions at issue in this case. Our scholarly interest in preemption arises from teaching and writing in a variety of related fields, including constitutional law, administrative law, health law, and torts.

This case implicates three critical issues in the law of preemption. First, Petitioner's amici have launched a broad attack on this Court's longstanding "presumption against preemption," …

Wnt5a Signaling Independently Of The Planar Cell Polarity Pathway Resulting In Convergent Extension And Neural Tube Closure During Vertebrate Development, Jared James Barrott

Theses and Dissertations

Vertebrate development is regulated by cellular communication by mechanisms of cell fate and cell behavior. These crucial mechanisms are regulated by cellular signaling and in the case of cell fate, cellular signaling results in transcription of developmentally important genes. Communication between cells can also result in regulation of cell behavior by acting on cytoskeletal elements rather than nuclear factors. One of the cellular signals that regulate both cell fate and cell behavior is the family of Wnt signaling molecules. Wnt5a is one of 19 Wnt molecules and has been previously demonstrated to play critical roles in many important processes in …

How Do Single Fathers Construct A Parent Identity To Incorporate Nurturing?, Janet Saxe

Theses, Dissertations, and Projects

This study explored how single fathers who had shared or sole physical custody of their children from a young age, thought and felt about their experience of nurturing. This qualitative, exploratory study aimed to broaden the knowledge of single fathers in this role, which has been largely unexplored. Heterosexual and gay fathers with shared or sole physical custody of their children from the age of four or under were recruited from New York and Massachusetts. Ten fathers participated in this study. Questions were grouped around topics such as: 1) the participants' experience of being parented; 2) the experience of being …

Exploring Internalized Racism : A Critical Review Of The Literature And Implications For Clinical Social Work, Keshia Unika Williams

Theses, Dissertations, and Projects

In social work, like many of its allied disciplines, the effects of racism on the racially oppressed has tended to focus on overt manifestations like violence and discrimination (Pyke and Dang, 2003). Largely missing from the mainstream social work literature is a clear and consistent definition and framework for internalized racism. An understanding of the deleterious effects of internalized racism- the subtle, often unconscious, processes by which racial inequality shapes the way that the oppressed think of themselves and other members of their group- is often lacking in clinical social work literature. Internalized racism represents a harmful consequence of a …

Examining Our Worst Fears, Jennifer Elmassian Leszkiewicz

Theses, Dissertations, and Projects

Fifty five graduate students in the 2008 class of Smith College School for Social Work, on average, seek symbolic immortality through existential themes, excluding religion. Additionally, the more students identify with themes that define meaning in their lives, the greater their fear of encountering threats to that meaning. Further, students reported that they daydream about existential fears that threaten symbolic immortality more frequently than they dream, or have memories of them; and that they dream about primal fears more frequently than they daydream, or have memories of them. This study tested the hypotheses that people fear what they imagine might …

The Role Of Psychotherapy In The Age Of Medication : A Theoretical Analysis Of Biological And Psychodynamic Perspectives On The Etiology And Treatment Of Schizophrenia, Tessa Leona Hutchinson

Theses, Dissertations, and Projects

This theoretical study explores the role of psychodynamic psychotherapy in the treatment of schizophrenia in an era where biologically oriented psychopharmacological interventions are the dominant treatment model. The study was undertaken as an effort towards clarification, as a graduate student from a psychodynamic training program, of how my training might possess or lack efficacy or application in my future work with those living with schizophrenia. Psychodynamic and biological perspectives on schizophrenia etiology and treatment have, throughout history, remained predominantly in opposition to one another. Currently neither perspective is able to fully explain the origins of schizophrenia, nor is the biologically-based …

What Are The Factors That Influence Whether A Clinician Discusses Race In The Crossracial Therapeutic Encounter?, Anna Cristina Goett

Theses, Dissertations, and Projects

This study attempts to gain insight into cross-racial therapy from the point of view of the clinician. Engaging in dialogues about race is one method identified in the literature that is said to facilitate the cross-racial therapeutic process. The primary research question is: What are the factors that influence whether a clinician discusses race in the cross-racial therapeutic encounter? This researcher hypothesizes that certain clinician characteristics, such as race, years of clinical experience, and graduate training affect the ways in which clinicians address racial difference in the cross-racial therapy. A quantitative survey was used to collect the data, and 56 …

Attachment Style And Identity Construction : The Choice Of Profession As One Method Of Culturally Mediating, Locating And Fulfilling Attachment Needs Both Interpersonally And Societally, Gwendolyn Cutting Wishard

Theses, Dissertations, and Projects

This mixed method study was undertaken to determine if successful professionals who are away from home for extended periods for work due to long hours and travel have particular types of close relationships, coping skills and identities. Secondly, the study examined whether their attachment styles as assessed by the quantitative measure, the Experiences in Close Relationships Scale -- ECR (Brennan, Clark and Shaver, 1998), revealed any relationships to their interview narratives concerning their professional successes, identities, close relationships in childhood and coping mechanisms. Using snowballing methods, successful professionals were recruited who had been in their careers for at least two …

The Double Bind Theory And Gender Non-Conforming Identity Development, Shannon Lydia Sennott

Theses, Dissertations, and Projects

The aim of this study was to qualitatively investigate the double binding effects of gender oppression on the lives of persons that self-identify as masculine-spectrum gender non-conforming. The qualitative interview used was designed to illuminate early memories of an individual's family of origin and the ways in which parents, siblings, and other primary support systems reacted to gender non-conforming behaviors in a child. The purpose of this study was to answer the following question: Is the identity development of a masculine-spectrum gender non-conforming person built on a relational foundation that is intra-psychically located within a double bind? The definition of …

An Investigation Into What "Best Practice" Entails With Adolescent Survivors Of Prolonged Child Abuse, Lauren P. Mcevoy

Theses, Dissertations, and Projects

This theoretical study explored the differences between narrative therapy (White, 2007a) and the family contextual model (Gold, 2000) in the treatment of adolescent survivors of prolonged childhood abuse (PCA). The aim of this research was to contribute to defining "best practice" with this population. Narrative therapy and the family contextual model were selected for this research because they are primarily client directed and trauma responsive as opposed to trauma focused. These were important considerations given the differences between the treatment needs of survivors of long-term childhood trauma, which are inevitably intertwined with development and attachment, and those of single-incident trauma …

A fidelity of 0.8 was also achieved using 40 m of fiber with 0.06-NA and a threshold power of 15 W. The fidelity …

Remote Sensing Observatory Validation Of Surface Soil Moisture Using Advanced Microwave Scanning Radiometer E, Common Land Model, And Ground Based Data: Case Study In Smex03 Little River Region, Georgia, U.S., Minha Choi, Jennifer M. Jacobs, David D. Bosch

Faculty Publications

Optimal soil moisture estimation may be characterized by intercomparisons among remotely sensed measurements, ground‐based measurements, and land surface models. In this study, we compared soil moisture from Advanced Microwave Scanning Radiometer E (AMSR‐E), ground‐based measurements, and a Soil‐Vegetation‐Atmosphere Transfer (SVAT) model for the Soil Moisture Experiments in 2003 (SMEX03) Little River region, Georgia. The Common Land Model (CLM) reasonably replicated soil moisture patterns in dry down and wetting after rainfall though it had modest wet biases (0.001–0.054 m3/m3) as compared to AMSR‐E and ground data. While the AMSR‐E average soil moisture agreed well with the other data sources, it had …

Determining The Role Of Wnt5a Signaling In Embryonic Limb Outgrowth Via Clonal Analysis, Whitney Herrod Sowby

Theses and Dissertations

The exact mechanisms that regulate limb outgrowth the mouse embryo are unknown. Although there are several models, we favor a hypothesis where cells become polarized by signals secreted from the AER which orient their cell migration and/or divisions causing limb outgrowth. Clonal analysis has provided a mechanism to study cell behavior. We have generated a targeting construct containing the Fgf8 inhibitor, Sprouty2, in order to generate mutant clones for behavioral analyses in the limb. In order to more effectively study clonal behavior we report the modification of a novel clonal analysis approach, exo-utero surgery. We have modified, enhanced and proven …

In 2007, following Demonstration Flight 2 - Falcon 1’s second demonstration mission, SpaceX declared Falcon 1 ready to exit the demonstration program and upgraded the vehicle to operational status. The mission was sponsored by the Defense Advanced Research Projects Agency (DARPA) and the US Air Force (USAF) with objectives centered on testing the vehicle in flight, gathering data and retiring technical risk prior to the first operational flight. This flight resulted in retiring significant risks in both the ground and flight systems. A review of the successes and achievements which led to the decision to go operational is presented along …

Rapid Satellite Deployment Of A Consumer Electronics Payload, Marit Meyer

Small Satellite Conference

Currently, launching a satellite into orbit is plausible only for organizations with multi-million dollar budgets and requires three or more years for development and qualification. Small satellites traveling as secondary payloads on regularly scheduled launches provide access to space at a fraction of the cost and in a fraction of the time. However, a modular adaptable satellite container can significantly reduce cost and development schedule. By sealing and pressurizing the container to maintain an earthlike environment in orbit, a payload of unmodified terrestrial electronics can be integrated and launched in a matter of weeks. Such a container, SCUTE (Sealed Container …

Claims Of Potential Expansion Throughout The U.S. By Invasive Python Species Are Contradicted By Ecological Niche Models, R. Alexander Pyron, Frank T. Burbrink, Timothy J. Guiher

Publications and Research

Background Recent reports from the United States Geological Survey (USGS) suggested that invasive Burmese pythons in the Everglades may quickly spread into many parts of the U.S. due to putative climatic suitability. Additionally, projected trends of global warming were predicted to significantly increase suitable habitat and promote range expansion by these snakes. However, the ecological limitations of the Burmese python are not known and the possible effects of global warming on the potential expansion of the species are also unclear. Methodology/Principal Findings Here we show that a predicted continental expansion is unlikely based on the ecology of the organism and …
