A Modular Mind? A Test Using Individual Data From Seven Primate Species, Federica Amici, Bradley Barney, Valen E. Johnson, Josep Call, Filippo Aureli Dec 2012

A Modular Mind? A Test Using Individual Data From Seven Primate Species, Federica Amici, Bradley Barney, Valen E. Johnson, Josep Call, Filippo Aureli

Faculty Articles

It has long been debated whether the mind consists of specialized and independently evolving modules, or whether and to what extent a general factor accounts for the variance in performance across different cognitive domains. In this study, we used a hierarchical Bayesian model to re-analyse individual level data collected on seven primate species (chimpanzees, bonobos, orangutans, gorillas, spider monkeys, brown capuchin monkeys and long-tailed macaques) across 17 tasks within four domains (inhibition, memory, transposition and support). Our modelling approach evidenced the existence of both a domain-specific factor and a species factor, each accounting for the same amount (17%) of the …

Evaluating Rawls: Equality In The Family, Devan Griffith Dec 2012

Evaluating Rawls: Equality In The Family, Devan Griffith

Honors Projects in History and Social Sciences

This paper examines the latest developments in feminist critiques of the seminal Theory of Justice, written by John Rawls, the late preeminent American moral philosopher. Rawls is recognized as one of the most influential moral political philosophers of the twentieth century and is increasingly relevant because of his discussions on pluralist societies. With the current diverging of liberal, conservative and libertarian philosophies among Americans, as well as the fragmentation of parties to accommodate an increasingly diverse public, a clear philosophy and understanding of liberal theory is necessary for its future in American politics. The current pressure to address the needs …

Information Content Of Seasonal Forecasts In A Changing Climate, Nir Krakauer, Michael D. Grossberg, Irina Gladkova, Hannah Aizenman Dec 2012

Information Content Of Seasonal Forecasts In A Changing Climate, Nir Krakauer, Michael D. Grossberg, Irina Gladkova, Hannah Aizenman

Publications and Research

We study the potential value to stakeholders of probabilistic long-term forecasts, as quantified by the mean information gain of the forecast compared to climatology. We use as a case study the USA Climate Prediction Center (CPC) forecasts of 3-month temperature and precipitation anomalies made at 0.5-month lead time since 1995. Mean information gain was positive but low (about 2% and 0.5% of the maximum possible for temperature and precipitation forecasts, resp.) and has not increased over time. Information-based skill scores showed similar patterns to other, non-information-based, skill scores commonly used for evaluating seasonal forecasts but tended to be smaller, suggesting …

Use Of International Hydrographic Organization Tidal Data For Improved Tidal Prediction, Songwei Qi Dec 2012

Use Of International Hydrographic Organization Tidal Data For Improved Tidal Prediction, Songwei Qi

Dissertations and Theses

Tides are the rise and fall of water level caused by gravitational forces exerted by the sun, moon and earth. Understanding sea level variation and its impact currents is very important especially in coastal regions. With knowledge of the tide-generating force and boundary conditions, hydrodynamic models can be used to predict or model tides in coastal regions. However, these models are not sufficiently accurate, and in-situ tide gauge data may be used to improve them in coastal regions. The International Hydrographic Organization (IHO) tidal data bank consists of over 4000 tide gauge stations scattered all around the globe, most of …

Tuning Of Alternative Splicing - Switch From Proto-Oncogene To Tumor Suppressor, Aleksandra Shchelkunova, Boris Ermolinsky, Meghan Boyle, Ivan Mendez, Michael Lehker, Karen S. Martirosyan, Alexander V. Kazanksy Dec 2012

Tuning Of Alternative Splicing - Switch From Proto-Oncogene To Tumor Suppressor, Aleksandra Shchelkunova, Boris Ermolinsky, Meghan Boyle, Ivan Mendez, Michael Lehker, Karen S. Martirosyan, Alexander V. Kazanksy

Health & Biomedical Sciences Faculty Publications

STAT5B, a specific member of the STAT family, is intimately associated with prostate tumor progression. While the full form of STAT5B is thought to promote tumor progression, a naturally occurring truncated isoform acts as a tumor suppressor. We previously demonstrated that truncated STAT5 is generated by insertion of an alternatively spliced exon and results in the introduction of an early termination codon. Present approaches targeting STAT proteins based on inhibition of functional domains of STAT's, such as DNA-binding, cooperative binding (protein-protein interaction), dimerization and phosphorylation will halt the action of the entire gene, both the proto-oncogenic and tumor suppressor functions …

Completion Of Hankel Partial Contractions Of Extremal Type, Raúl E. Curto, Sang Hoon Lee, Jasang Yoon Dec 2012

Completion Of Hankel Partial Contractions Of Extremal Type, Raúl E. Curto, Sang Hoon Lee, Jasang Yoon

School of Mathematical & Statistical Sciences Faculty Publications

We find concrete necessary and sufficient conditions for the existence of contractive completions of Hankel partial contractions of size 4 × 4 in the extremal case. Along the way we introduce a new approach that allows us to solve, algorithmically, the contractive completion problem for 4 × 4 Hankel matrices. As an application, we obtain a concrete example of a partially contractive 4 × 4 Hankel matrix, which does not admit a contractive completion.

Toward Legalization Of Poker: The Skill Vs. Chance Debate, Robert C. Hannum, Anthony N. Cabot Dec 2012

Toward Legalization Of Poker: The Skill Vs. Chance Debate, Robert C. Hannum, Anthony N. Cabot

UNLV Gaming Research & Review Journal

This paper sheds light on the age-old argument as to whether poker is a game in which skill predominates over chance or vice versa. Recent work addressing the issue of skill vs. chance is reviewed. This current study considers two different scenarios to address the issue: 1) a mathematical analysis supported by computer simulations of one random player and one skilled player in Texas Hold'Em, and 2) full-table simulation games of Texas Hold'Em and Seven Card Stud. Findings for scenario 1 showed the skilled player winning 97 percent of the hands. Findings for scenario 2 further reinforced that highly skilled …

Relating Nanoparticle Properties To Biological Outcomes In Exposure Escalation Experiments, Trina Patel, Cecile Low-Kam, Zhaoxia Ji, Haiyuan Zhang, Tian Xia, Andre E. Nel, Jeffrey I. Zinc, Donatello Telesca Dec 2012

Relating Nanoparticle Properties To Biological Outcomes In Exposure Escalation Experiments, Trina Patel, Cecile Low-Kam, Zhaoxia Ji, Haiyuan Zhang, Tian Xia, Andre E. Nel, Jeffrey I. Zinc, Donatello Telesca

COBRA Preprint Series

A fundamental goal in nano-toxicology is that of identifying particle physical and chemical properties, which are likely to explain biological hazard. The first line of screening for potentially adverse outcomes often consists of exposure escalation experiments, involving the exposure of micro-organisms or cell lines to a battery of nanomaterials. We discuss a modeling strategy, that relates the outcome of an exposure escalation experiment to nanoparticle properties. Our approach makes use of a hierarchical decision process, where we jointly identify particles that initiate adverse biological outcomes and explain the probability of this event in terms of the particle physico-chemical descriptors. The …

Game Theory Approach To Transportation Network Vulnerability Measurement, Qixing Wang Dec 2012

Game Theory Approach To Transportation Network Vulnerability Measurement, Qixing Wang

Master's Theses

The vulnerability of a transportation network is strongly correlated with the ability of the network to withstand shocks and disruptions. A robust network with strategic redundancy allows for the redistribution or reassignment of traffic without unduly compromising system performance. As such, high-volume edges with limited alternative paths represent system vulnerabilities – a feature of transportation networks that has been exploited in the past to identify critical components. In this thesis, a mixed-strategy, two opponents, non-zero sum, combinatorial game theoretical framework are presented for measuring network vulnerability. Two solution approaches (Shortest Path Algorithm with Entropy function (SPE) & User Equilibrium Assignment …

Applicability Of The Duplication Of Purchase Law To Gaming, Desmond Lam Dec 2012

Applicability Of The Duplication Of Purchase Law To Gaming, Desmond Lam

UNLV Gaming Research & Review Journal

In a bid to explore the use of an empirical-based model to explain regular gaming purchases, this study applies the Duplication of Purchase Law to gaming. Developed from empirical-based marketing theory and observed in many consumer brands, the Duplication of Purchase Law states that the dominant factor of purchase duplication between two brands is their market share. Using data obtained from the U.S. Gambling Impact Study, this study found that the duplication of games played was highly correlated to their penetration rates and hence, market share. In addition, the number of sole gamblers in each game was also related to …

Two Consumption Models For United States Casino Areas Utilizing Competition And Site Attribute Variables, David M. Pearlman Dec 2012

Two Consumption Models For United States Casino Areas Utilizing Competition And Site Attribute Variables, David M. Pearlman

UNLV Gaming Research & Review Journal

In this study, multiple regression techniques were used to build two consumption models to better understand supply and demand influences on casino revenues. The initial model contained 15 independent variables and explained 97% of the variance in revenues. However, due to assumption violations, assessing the relative role of each independent variable proved to be problematic. Subsequently, a Reduced Variable Model was developed which explained 83% of the variance, and included six independent variables. As stand-alone prediction tools, the models do not yield useful revenue estimates, due to their large standard errors of the estimate, however, they do explain relative influences …

Educating For The Gaming Industry: Need, Profile, And Suggested Schema, Leslie E. Cummings Dec 2012

Educating For The Gaming Industry: Need, Profile, And Suggested Schema, Leslie E. Cummings

UNLV Gaming Research & Review Journal

As legalized gambling becomes increasingly widespread and competitive, operators seek employees who understand its unique culture and demands. Today, few baccalaureate programs offer gaming management education. Gaming subject areas for college programs span three content spheres: (a) gaming and games themselves; (b) gaming interfaces with other hospitality subjects (lodging, accounting); and (c) the gaming/hospitality environment (regulation, economics). In a given academic program, gaming content integration can be measured along a continuum, from nonexistent, to somewhat integrated within existing courses, to comprising a central educational focus.

Mentorship Modes: Strategies For Influencing Interactive Learners, Brad Gyori Dec 2012

Mentorship Modes: Strategies For Influencing Interactive Learners, Brad Gyori

Interdisciplinary Journal of Problem-Based Learning

In the age of the Internet, students are clamoring for immersive and participatory learning experiences, but how can teachers share autonomy without losing control of their classrooms? In an effort to address this important question, this article suggests three mentorship modes that educators can employ in order to effectively engage with today’s interactive learners. Lecture-based instruction is a single mode form of teaching in which information is disseminated by a lone authority-figure. In contrast, learning-centered mentorship is a three-mode process in which autonomy is shared and authority flows in multiple directions at once: bottom-up (modeling), laterally (collaborating), and top-down (organizing …

The Moral Foundations Of Ethical Leadership, Joseph Hester, Don R. Killian Dec 2012

The Moral Foundations Of Ethical Leadership, Joseph Hester, Don R. Killian

The Journal of Values-Based Leadership

Hester and Killian stress that principled leadership does not necessarily require discarding past practices; rather, they emphasize the importance of using what is good about the past, eliminating self-interest, and injecting passion into contemporary, valuesbased leadership. Passion, as used by the authors in this sense, refers to neither rage nor anger; rather, it is an excitement and enthusiasm that comes from leading with vision, integrity, and respect for others. Subsequently, when such passion is coupled with moral purpose, the idea of serving others, and building and sustaining relationships, the organization will inevitably experience positive growth — one person at a …
