Stimulus–Response Congruency Effects Depend On Quality Of Perceptual Evidence: A Diffusion Model Account, Blaine Tomkins

Psychology Faculty Publications

Individuals often need to make quick decisions based on incomplete or “noisy” information. This requires the coordination of attentional, perceptual, cognitive, and behavioral mechanisms. This poses a challenge for isolating the unique effects of each subprocess from behavioral data, which reflect the summation of all subprocesses combined. Sequential sampling models offer a more detailed examination of behavioral data, enabling us to separate decisional and non-decisional processes at play in a task. Participants were required to identify briefly presented shapes while perceptual (duration, size, location) and response features (location-congruent/-incongruent/-neutral) of the task were manipulated. The diffusion model (Ratcliff, 1978) was used …

The Tragedy Of The Common? A Comparative Population Genomic Study Of Two Bumblebee Species, Jana V. Huml, Jonathan S. Ellis, Sarah Rustage, Mark J.F. Brown, Richard Billington, Mairi E. Knight

School of Biological and Marine Sciences

Within the theoretical framework of the small population paradigm, we investigated the population genomics and parasite load of two bumblebee species across the UK and Ireland. Bombus pratorum is widespread and common throughout its range while Bombus monticola is restricted to higher altitudes and shows a more fragmented distribution. Bombus monticola showed stronger population structuring, isolation-by-distance, and a deficit of heterozygotes in the most isolated population in the south of its range (Dartmoor). Heterozygosity and inbreeding coefficients (FIS) were comparable between both species, but the proportion of polymorphic sites was much greater in B. pratorum. Notably, both species have suffered …

Nest Material Preferences In Wild Hazel Dormice Muscardinus Avellanarius: Testing Predictions From Optimal Foraging Theory, Sa Collins, Sm Lane, M Ishibashi, T Hamston

School of Biological and Marine Sciences

Obtaining nesting material presents an optimal foraging problem, collection of materials incurs a cost in terms of risk of predation and energy spent and individuals must balance these costs with the benefits of using that material in the nest. The hazel dormouse, Muscardinus avellanarius is an endangered British mammal in which both sexes build nests. However, whether material used in their construction follows the predictions of optimal foraging theory is unknown. Here, we analyze the use of nesting materials in forty two breeding nests from six locations in Southwest England. Nests were characterized in terms of which plants were used, …

Cell Type Classification Via Deep Learning On Single-Cell Gene Expression Data, Shanta Chowdhury

All Dissertations

Single-cell sequencing is a recently advanced revolutionary technology which enables researchers to obtain genomic, transcriptomic, or multi-omics information through gene expression analysis. It gives the advantage of analyzing highly heterogenous cell type information compared to traditional sequencing methods, which is gaining popularity in the biomedical area. Moreover, this analysis can help for early diagnosis and drug development of tumor cells, and cancer cell types. In the workflow of gene expression data profiling, identification of the cell types is an important task, but it faces many challenges like the curse of dimensionality, sparsity, batch effect, and overfitting. However, these challenges can …

Performance Analysis Of Hybrid Ai-Based Technique For Maximum Power Point Tracking In Solar Energy System Applications, Adeyemi R. Taylor

All Dissertations

Demand is increasing for a system based on renewable energy sources that can be employed to both fulfill rising electricity needs and mitigate climate change. Solar energy is the most prominent renewable energy option. However, only 30%-40% of the solar irradiance or sunlight intensity is converted into electrical energy by the solar panel system, which is low compared to other sources. This is because the solar power system's output curve for power versus voltage has just one Global Maximum Power Point (GMPP) and several local Maximum Power Points (MPPs). For a long time, substantial research in Artificial Intelligence (AI) has …

Cognitive-Experiential Self-Theory: An Analysis Of Teen Court Decision-Making By Youth Jurors And Adult Volunteers, Colette Briana Harris

All Dissertations

Few studies have explored the effects of emotional or rational stimulations concerning juror verdicts. There has yet to be a study to examine the impact of cognitive or experiential processing on teen juror decision-making in teen courts. The survey of teen court participants after the completion of teen court jury trials was used to gauge whether rational processing or experiential processing was triggered in selecting a verdict. Cognitive-Experiential Self-Theory (CEST) and juvenile decision-making theories and perspectives (The Focal Concerns Theory of Sentencing, Attribution Theory, and Formal Legal Perspective) were used to explain teen jurors’ decision-making. A sample of 107 grade, …

Invariants Of 3-Braid And 4-Braid Links, Mark Essa Sukaiti

Theses

In this study, we established a connection between the Chebyshev polynomial of the first kind and the Jones polynomial of generalized weaving knots of type W(3,n,m).
Through our analysis, we demonstrated that the coefficients of the Jones polynomial of weaving knots are essentially the Whitney numbers of Lucas lattices which allowed us to find an explicit formula for the Alexander polynomial of weaving knots of typeW(3,n).
In addition to confirming Fox’s trapezoidal conjecture, we also discussed the zeroes of the Alexander Polynomial of weaving knots of type W(3,n) as they relate to Hoste’s conjecture. In addition, …

Using Metal-Organic Frameworks (Mofs) In Producing Self-Curing Concrete, Lama Fathi Allan

Theses

Curing of concrete is the presence of adequate moisture content in concrete throughout its early stages to produce the desired properties, as it is significant in improving the concrete microstructure and pore structure and hence in developing its performance and durability. However, good curing is not always practical in several cases, such as in hot weather regions and areas of water inadequacy. For that reason, the need to develop self-curing concrete attracted several researchers. The use of self-curing agents minimizes the water evaporation from concrete and consequently increases its water retention capacity compared to conventional concrete. This thesis is concerned …

Electrodialysis Process For The Simultaneous Treatment Of Reject Brine And Capture Of Carbon Dioxide, Jawad Mustafa

Dissertations

Desalination plants are highly efficient in producing desalinated water for potable applications. However, the process also generates reject brine, which is highly concentrated saline water. In order to produce 1 liter of potable water using desalination, approximately 1.5 liters of reject brine is generated. The disposal of reject brine presents a significant challenge for the desalination industry. Typically, this waste product is discharged into the sea, causing environmental damage, and polluting marine life. Moreover, certain countries heavily rely on desalination to meet their potable water needs, which results in the emission of greenhouse gases. As desalination plants consume a significant …

Characterization Of Piezoelectric Coefficient Using Combined Optical And Electrical Methods, Limna Sainudeen Attoor

Algorithms, Leadership, And Morality: Why A Mere Human Effect Drives The Preference For Human Over Algorithmic Leadership, Jack Mcguire, David De Cremer

Research Collection Lee Kong Chian School Of Business

Algorithms are increasingly making decisions in organizations that carry moral consequences and such decisions are considered to be ordinarily made by leaders. An important consideration to be made by organizations is therefore whether adopting algorithms in this domain will be accepted by employees and whether this practice will harm their reputation. Considering this emergent phenomenon, we set out to examine employees’ perceptions about (a) algorithmic decision-making systems employed to occupy leadership roles and make moral decisions in organizations, and (b) the reputation of organizations that employ such systems. Furthermore, we examine the extent to which the decision agent needs to …

Manufacturing Uncertainty In Constitutional Law, Ari Ezra Waldman

Fordham Law Review

Civil rights litigation is awash in misinformation. Litigants have argued that abortion causes cancer, that gender-affirming hormone therapy for adolescents is irreversible, and that in-person voter fraud is a massive problem. But none of that is true. The conventional scholarly account about law and misinformation, disinformation, and dubious claims of fact focuses on the power of legislatures and amici to engage in perfunctory fact-finding and to rely on “alternative facts” or outright falsehoods to justify laws that harm and restrict the rights of marginalized populations. At the same time, the literature suggests that judges and the law are inundated with …

Ripple Effect: The Sec's Major Questions Doctrine Problem, Matt Donovan

Fordham Law Review

Crypto assets and blockchain technology have the potential to create unprecedented equitable access to financial institutions. Despite this potential, there is a robust debate regarding federal agencies’ jurisdiction over the novel asset class. Without clear statutory guidelines, federal agencies have been forced to resolve this debate through the rulemaking process. However, agency rules regarding jurisdiction over crypto assets could be scrutinized by a reviewing court under the major questions doctrine. Once highly deferential to agency rules, the U.S. Supreme Court in recent terms has repeatedly struck down agency rules when an agency claims an unheralded power to regulate an issue …

Close Enough To Stand?: Reconsidering The Fair Debt Collection Practices Act's Relationship With The Right To Privacy, Ryan Karerat

Fordham Law Review

With the passage of the Fair Debt Collection Practices Act (FDCPA) in 1977, Congress created a private right of action through which consumers could sue debt collectors for overzealous and improper conduct traceable to their debt collection efforts. FDCPA violations can abridge a consumer’s rights under the statute without producing tangible economic or physical injury. As a result, many plaintiffs bringing claims under the FDCPA plead different theories of intangible harm to establish the required injury in fact conferring Article III standing to file suit in federal court. To establish that they have suffered an injury in fact, a plaintiff …

Criminalizing Threats Against Schools: A Divergence Of Mens Rea And Punishment Severity In Recent State Legislation, Max Kaufman

Fordham Law Review

School shootings occur on a regular basis in the United States. Fear of the next school shooting leads schools to take any potential threat of violence seriously, but responding to a threat can be extremely disruptive to a school’s operations and the community that it serves. In the last five years, nine state legislatures have attempted to deter these threats by specifically criminalizing threats of violence against schools.

Despite the proximity in time in which these states enacted school threat statutes, these laws diverge in two important ways: First, the nine statutes employ several different mens rea requirements. Second, these …

Forum Selection Provisions And The Preclusion Of Derivative Claims Under Section 14(A) Of The Securities Exchange Act: Should Federal Courts Intervene?, Noah P. Mathews

Fordham Law Review

This Note examines whether a forum selection provision in a corporation’s bylaws that requires shareholders to bring derivative claims in the Delaware Court of Chancery is enforceable when invoked by directors to dismiss derivative claims under the Securities Exchange Act (the “Exchange Act”)—claims over which federal courts have exclusive jurisdiction. In Seafarers Pension Plan ex rel. Boeing Co. v. Bradway, the U.S. Court of Appeals for the Seventh Circuit held that enforcing this type of bylaw would violate the act’s antiwaiver provision, which voids any stipulation that allows a person to waive compliance with the act. In Lee ex …

Dirty Dancing: Is The Texas Two-Step A Bad Faith Filing?, Katharine H. O'Neill

Fordham Law Review

The Texas Two-Step is both a style of line dancing and a legal maneuver used by several large, profitable companies to enable a newly created entity to access the bankruptcy system and, thus, discharge the tort liabilities of its predecessor. This type of filing has been criticized by some as a tool used by healthy companies to evade responsibility for their tortious conduct and lauded by others as an efficient means to achieve a global resolution of crushing mass tort liability. Whether Texas Two-Step filings may properly access the bankruptcy courts is a question governed by § 1112(b) of the …

Bridging The Ai Inventorship Gap, Jeffrey Wu

Fordham Law Review

In Thaler v. Vidal, the U.S. Court of Appeals for the Federal Circuit ruled that an artificial intelligence (AI) machine cannot be an inventor under patent law. This decision leaves open the question of whether a natural person can be the legal inventor of AI-generated inventions. This is a pressing question because it decides whether AI-generated inventions are patentable, as no patent rights can exist without an inventor.

Scholars have proposed two doctrines that might resolve this question: (1) the doctrine of simultaneous conception and reduction to practice and (2) the doctrine of first to recognize and appreciate. This …

Peak To Average Power Ratio Reduction In Spectrally Efficient Fdm Using Repeated Clipping And Filtering, Buthaina Mosa Omran, Yamaan Esmiel Majeed, Iftekhar Ahmad

Research outputs 2022 to 2026

Multi-carrier transmission may be considered one of the important developments in wireless communications. Spectrally efficient frequency division multiplexing (SEFDM) is a promising multi-carrier modulation which can significantly improve utilization of spectral. The SEFDM has high peak to average power ratio (PAPR) like any multicarrier system. High PAPR reduces the random forest (RF) transmitter power amplifier efficiency, which minimize the use of this technique in limited power supply transmitters. In this work, a repeated clipping and filtering method is introduced to reduce the PAPR in SEFDM with minimum or no out of band radiation. The results of the simulated approach show …
