From Arms Race To Marketplace: The Complex Patent Ecosystem And Its Implications For The Patent System, Colleen V. Chien

UC Law Journal

For years, high-tech companies have amassed patents in order to deter patent litigation. Recently, a secondary market for patents has flourished, making it more likely that patents that would otherwise sit on the shelf will end up in the courtroom. This Article explores the current patent ecosystem, which includes both “arms race” and “marketplace” paradigms, in depth. I distinguish “patent-assertion entities,” entities that use patents primarily to obtain license fees rather than to support the development or transfer of technology, from other types of non-practicing entities. I contrast the patent arms race, whose goal is to provide entities with the …

Stanley In Cyberspace: Why The Privacy Protection Of The First Amendment Should Be More Like That Of The Fourth, Marc Jonathan Blitz

UC Law Journal

The 1969 case Stanley v. Georgia forbade the government from restricting the books that an individual may read or the films he may watch “in the privacy of his own home.” Since that time, the Supreme Court has repeatedly emphasized that Stanley’s protection applies solely within the physical boundaries of the home: While obscene books or films are protected inside of the home, they are not protected en route to it—whether in a package sent by mail, in a suitcase one is carrying to one’s house, or in a stream of data obtained through the Internet. However adequate this narrow …

Perception Of Control: Accuracy Among Optimists And Pessimists On Noncontingency And Contingengy Tasks, Spencer Baunn M.S.

All-Inclusive List of Electronic Theses and Dissertations

The learned helplessness theory asserts that depressed individuals unrealistically believe that they have little to no control over aversive outcomes in their lives. Paradoxically, research on judgment of control has demonstrated that depressed individuals are not necessarily pessimistic, but rather more realistic than non-depressed individuals. Most of the research on depressive realism has investigated individual’s perceived control in situations in which they have no actual control. Few studies have investigated perception of control in situations where control is possible. Considering that many circumstances in life are controllable, it is important to examine how different personality variables contribute to accurate judgments …

The Status Of Crawfish Frogs (Lithobates Areolatus) In Indiana, And A Tool To Assess Populations, Nathan J. Engbrecht

All-Inclusive List of Electronic Theses and Dissertations

The conservation status of Crawfish Frogs (Lithobates areolatus) in Indiana has changed over the past several decades. Once described as being locally plentiful, declines led to the listing of Crawfish Frogs as a State Endangered Species in 1988. Several records for this species in Indiana are > 50 yrs old and have gone unconfirmed for several decades. However, recent surveys have confirmed the continued presence of Crawfish Frogs in parts of southern Indiana, redefining the perceived range of this species in the state. In an effort to increase survey efficiency in this species, I used automated recording systems and manual call …

Singular Value Decomposition Metrics Show Limitations Of Detector Design In Diffuse Fluorescence Tomography, Frederic Leblond, Kenneth M. Tichauer, Brian W. Pogue

Dartmouth Scholarship

The spatial resolution and recovered contrast of images reconstructed from diffuse fluorescence tomography data are limited by the high scattering properties of light propagation in biological tissue. As a result, the image reconstruction process can be exceedingly vulnerable to inaccurate prior knowledge of tissue optical properties and stochastic noise. In light of these limitations, the optimal source-detector geometry for a fluorescence tomography system is non-trivial, requiring analytical methods to guide design. Analysis of the singular value decomposition of the matrix to be inverted for image reconstruction is one potential approach, providing key quantitative metrics, such as singular image mode spatial …

Grand Jury Innovation: Toward A Functional Makeover Of The Ancient Bulwark Of Liberty, Roger Fairfax

Scholarly Articles in Law Reviews & Journals

The grand jury is a "much maligned" organ of the criminal justice system.' Regularly employed in only about half of the states and grudgingly tolerated in the federal system,2 the American grand jury for two centuries has been criticized as costly, ineffective, overly-compliant, and redundant. Prescriptions have ranged from reforms designed to improve the grand jury's performance of its traditional filtering and charging functions to the outright abolition of the grand jury. Consequently, much of the scholarly defense of the grand jury seemingly has done little more than attempt to justify its very existence.

This Article seeks to take the …

This study explored elementary school counselors' perceptions of working with students exposed to violent video games. Certified elementary school counselors participated in both an online survey and individual interviews, revealing their observations regarding elementary school children and the phenomenon of gaming. An emphasis was placed on information about violent video games and how playing these games appear to impact the students in their schools.;The study addressed the overarching question of whether or not elementary school counselors have concerns about student exposure to violent video games and how they respond to student generated discussions of playing violent video games. The study …

Development And Evolution Of Higher Brain Centers In Insects, Xiangyi Zhao

Graduate Theses, Dissertations, and Problem Reports (ETD)

Brain structures within an individual can change during development through modification of individual neuron morphology together with alteration of neuron numbers. Differences in the same or analogous brain structures from different species can reflect behavioral pattern variation among these species fixed by natural selection. This study used insects from two different taxonomic groups to address such brain structure changes at these two time scales: developmental and evolutionary. Mushroom bodies, as an integrative sensory center involved in learning and memory in insects, were the main structure surveyed to illustrate changes in higher brain centers in both projects. In the developmental study, …

The Power-Knowledge To Move Mountains: Subaltern Discourses Of Mountaintop Removal In Coal River Valley, West Virginia, Jen Osha

Graduate Theses, Dissertations, and Problem Reports (ETD)

This research investigates the perspectives of local residents within the Coal River Valley, WV, who are concerned about the impacts of mountaintop removal (MTR) on themselves, their families and communities, and their environment. In this dissertation, the term 'subaltern' represents a heterogeneous community of resistance to MTR with multiple perspectives around intersections of gender, age, and livelihood. The objectives of my study are twofold: to illuminate how dominant legal discourse continues to subjugate the discourse of resistance to MTR, and to identify possible spaces of resistance within which the subaltern discourse can challenge the power relations that continue to permit …

Simulation-Based Optimum Design Of Sensor Arrays Using Multi-Objective Tabu Search, Zongyu Geng

Graduate Theses, Dissertations, and Problem Reports (ETD)

This thesis is concerned with the optimum design of sensor arrays (i.e., electronic noses or tongues) using simulation experiments. The proposed design method adopts a set of new criteria, which more adequately represent the desirable properties of a sensor array in practice. A number of best non-dominated array designs are selected through a multiple objective (criteria) Tabu search algorithm. The evaluation of a candidate sensor array is based on its multivariate calibration model, which is efficiently estimated from well-designed simulation experiments. The method can be used to optimize the design of both linear and nonlinear sensor arrays.

The Usu Tree Inventory Website: A Case Study Of An Interactive Online Woody Plant Education Resource, Benjamin W. Harris

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The USU tree inventory website is an interactive, online tree education resource that I developed to allow students and community members to locate, identify and learn about trees on the USU campus. Students in two USU courses that teach woody plant material used the website during one semester and were surveyed about their experience. Less than half of the students accessed the website, but those that did found it useful as a supplement to traditional instruction. Most students were likely to recommend the website to another person and to use the website in the future.

Civil and Environmental Engineering Faculty Publications

© 2010 by the authors. This study examines the suitability of natural silica sand as a low-cost adsorbent for the removal of ammoniacal nitrogen and heavy metals, particularly iron and zinc, from semi-aerobic stabilized landfill leachate. Leachate samples were collected from the Pulau Burung landfill site (PBLS) in Penang, Malaysia. The above-mentioned contaminants are highlighted in this study because of their unsafe concentrations at PBLS. The effects of shaking time, settling time, and silica sand dosage on the study parameter removal efficiencies were investigated to predict the performance of the process. The adsorptions of ammoniacal nitrogen, iron, and zinc were …

A Study Of The Effect Of Vibration On Railroad Bearing Temperature, Bertha Alicia Gonzalez

Theses and Dissertations - UTB/UTPA

An on-track collaborative field test and laboratory experiments were conducted in order to determine the relationship between abrupt rises in surface temperature of a railroad bearing and vibration signatures captured during the experiments. The collaborative field test was conducted in order to investigate the root cause for this abrupt temperature change known as bearing temperature trending. The research presented in this thesis will show that temperature trending is correlated to an increase in the magnitude of vibration within the bearing and the fundamental frequencies that are generated by the internal components of a rotating bearing assembly. Distinct vibration mechanisms are …

Context Versus Rote Learning In The Martial Arts, Pearson F. Klein

Theses and Dissertations - UTB/UTPA

Research has shown that when learning martial arts katas, adults retained the information better “when the katas were taught with the context method than when the katas were taught with the no context method.” (Tovar, M.) It is imperative more experimentation be performed in this area because the findings do not relate to the population of children. Children between ages seven and twelve were instructed in two original katas utilizing two methods of instruction. First the katas with context were taught and then the other taught was purely based on rote completion of the sequential movements. Every subject was tested …

Attitudinal Measures Of College Students' Punitiveness Toward Sex Offenders, Antonio Zamorano

Theses and Dissertations - UTB/UTPA

The following experiment investigates punitiveness toward sex offenders using a sample of one hundred sixty students from the University of Texas-Pan American student population recruited from undergraduate introductory psychology courses and compensated with extra course credit. Punitiveness toward sex offenders was measured with six-point bipolar Likert scales using two attitudinal research methodologies: a randomly assigned between group experiment using a manipulated hypothetical crime scenario, and a survey using a shortened version of the Community Attitudes Toward Sex Offenders Scale (CATSOS). A one-way analysis of variance (ANOVA) and multiple comparison tests of attitudinal responses to the hypothetical crime scenario determined that …

Investigating Heavy Metal Accumulation And Oxidative Stress Tolerance Of Non-Accumulators And Hyperaccumulators In The Brassicaceae Plant Family, Fritzie Joy Into

Theses and Dissertations - UTB/UTPA

Physiological and enzymatic analysis indicated that the non-accumulator A. thaliana showed an oxidative stress response in all assays except for protein carbonylation. Other non-accumulator plant species showed a significant difference in oxidative stress response in the TBARS assay; however, for some assays no stress response was evident. The hyperaccumulator plant species showed no significant difference in oxidative stress as indicated by the all of the assays with the exception of T. montanum var. montanum which showed an oxidative stress response in the SOD assay. Basal catalase enzyme activity was notably higher in the hyperaccumulators T. montanum var. montanum and T. …

Alignment Of Community Preferences, Economic Development Goals, And Policy: Considering Economic Development Goals, Their Expression, And Their Execution In Economically Struggling Communities, Rebecca Lynn Moryl

Graduate Doctoral Dissertations

Across the U.S., and particularly in the Northeast, cities known as former "mill towns" have been largely unsuccessful in attempts to revive their economic vigor. States and cities invest millions each year in efforts to reinvigorate these cities through economic development policies. Debates about the effectiveness of such policies in generating economic growth outcomes are prevalent in the literature. This thesis takes a different focus by considering the alignment of economic development goals and actions among citizens and government professionals. I consider, compare, contrast, and draw lessons from three Massachusetts cities of similar government structure. Each of these cities has …

Unattainable Beauty: An Analysis Of The Role Of Body Shame And Self-Objectification In Hopelessness Depression Among College-Age Women, Meredith A. Evans

Graduate Doctoral Dissertations

Despite substantial evidence that women suffer from depression at twice the rate of men, the etiology for this difference remains unclear. Prior to puberty, the difference in depression is negligible; however, when adolescence begins, a precipitous rise in female depression occurs that persists across the lifespan. While no definitive biological change has been linked to this phenomenon, objectification theory (Frederickson & Roberts, 1997) can be used to gain insight into the social influences at play during that transitional period. This study of 269 undergraduate women from a northeastern university used structural equation modeling to propose a path leading from self-objectification …

Worker Cooperatives And Revolution: History And Possibilities In The United States, Christopher Wright

Graduate Masters Theses

Worker cooperatives have a long and tortured history, but recently they have been advancing globally on a more stable foundation than before. In this essay I provide a theoretical context for the current growth of cooperatives, drawing on Marxist theory to illuminate their potential. I also consider the sociology and economics of worker cooperatives, in addition to expounding and evaluating their history in the United States.

A case-study of a cooperative printing press in Jamaica Plain gives a more intimate portrayal of worker co-ops, and hopefully provides lessons for future cooperators. I interpret society as on the cusp of a …

The Role Of Pkd1 In Mouse Inner Ear Hair Cells, Katherine Ann Steigelman

Theses and Dissertations (ETD)

The polycystic kidney disease-1 (Pkd1) gene encodes a large transmembrane protein (polycystin-1 or PC-1) that is reported to function as a fluid flow-sensor in the kidney. As a member of the transient receptor potential (TRP) family, PC-1 has also been hypothesized to play a role in the elusive mechanoelectrical transduction (MET) channel in inner ear hair cells based on PC-1 role of fluid flow sensing and calcium uptake into renal epithelial cells. However, two independent mouse lines with PC-1 mutations exhibit normal MET channel function despite hearing loss and ultra-structural abnormalities of stereocilia that remain properly polarized at …

Ferric Iron Nanoparticle Formation Mediated By Negatively Charged Polypeptides, Vamsi Krishna Aluru

Graduate Theses, Dissertations, and Problem Reports (ETD)

The creation of magnetite particles by magnetotactic bacteria has been of great interest for a number of years. Previous studies have shown that magnetite nanocrystals have been synthesized in the presence of recombinant Mms6 protein. Mms6 plays a vital role in the biomineralization of bacterial magnetite nanocrystals. The objective of this research is to determine the effect of functional group type on size and shape of magnetic nanoparticles formed by biomineralization. Control over the size of nanoparticles is paramount. Use of nanoparticles as contrast agents in MRI is advantageous, as they are small enough to be localized in desired region …

Developing A Cellular Assay For Screening Inhibitors Of Stat4 Phosphorylation, Vivian Marcela Suarez

Graduate Theses, Dissertations, and Problem Reports (ETD)

In order to design better therapeutic strategies, scientists work on understanding the interactions that take place at cell level and have an effect on the immune system. In order to identify a few possible inhibitors that may be up-regulated in tumor environment and that may affect T-cell action, a cellular assay was designed. An Interleukin-12 (IL-12)-responsive murine Th1 cell clone called 2D6 was used as cellular model to study the effects of transforming growth factor-beta (TGF-beta), insulin, and interleukin-6 (IL-6) on the phosphorylation of Signal transducer and activator of transcription 4 (STAT4), a key element in IL-12 signaling. Cells were …

Using Environmental And Site-Specific Variables To Model Current And Future Distribution Of Red Spruce (Picea Rubens Sarg.) Forest Habitat In West Virginia, Nathan R. Beane

Graduate Theses, Dissertations, and Problem Reports (ETD)

Red spruce forests are a remnant ecosystem from the interglacial period of the Wisconsin glaciation and today are considered one of the most threatened forest ecosystems in the eastern United States. The extent of red spruce forests in West Virginia prior to exploitative logging which occurred from 1880--1920 is estimated at 190,000 ha, but today, these forests are estimated to occupy no more than 24,000 ha, resulting primarily from intense anthropogenic disturbances. With the extensive loss of presettlement habitat for red spruce in West Virginia, this species is a high priority for restoration, as these forests offer the unique habitat …

High Rank Tensor And Spherical Harmonic Models For Diffusion Mri Processing, Inas A. Yassine

Graduate Theses, Dissertations, and Problem Reports (ETD)

Diffusion tensor imaging (DTI) is a non-invasive quantitative method of characterizing tissue micro-structure. Diffusion imaging attempts to characterize the manner by which the water molecules within a particular location move within a given amount of time. Measurement of the diffusion tensor (D) within a voxel allows a macroscopic voxel-averaged description of fiber structure, orientation and fully quantitative evaluation of the microstructural features of healthy and diseased tissue.;The rank two tensor model is incapable of resolving multiple fiber orientations within an individual voxel. This shortcoming of single tensor model stems from the fact that the tensor possesses only a single orientational …

Effectiveness Of Cetylpyridinium Chloride, Chlorhexidine Gluconate, Chlorine Dioxide, And Essential Oils Against F. Nucleatum, P. Gingivalis, S. Mutans And S. Sobrinus---A Biofilm Approach, Kristafer Lee Adkins

Graduate Theses, Dissertations, and Problem Reports (ETD)

Results of evaluating chemotherapeutic effectiveness have focused on planktonic, two-dimensional bacterial existence. Biofilms exist as three-dimensional structures which shelter bacteria deep within. Current research is needed to evaluate the effectiveness of various chemotherapeutics against bacteria residing inside of a biofilm. In order to do so, this study evaluated the effectiveness of four common chemotherapeutics (cetylpyridinium chloride, chlorhexidine gluconate, chlorine dioxide, and essential oils) against four bacteria (S. mutans, S. sobrinus, F. nucleatum and P. gingivalis) in both planktonic and biofilm modeled culture media. Data was obtained through the measurement of zones of inhibition (ZOI) surrounding test discs placed on experimental …
