Behavioral Reactions To Emotional And Physical Infidelity: An Evolutionary Perspective, Mandy Walsh Walsh

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis examined the effects of sex and type of partner infidelity, including both physical (i.e., sexually involved with another person) and emotional (i.e., emotionally involved with another person) infidelity, on mate abandonment behaviors. Previous research has demonstrated sex differences in emotional responses to infidelity, where men react more negatively to physical infidelity and women react more negatively to emotional infidelity. While various studies have investigated perceived behavioral reactions using imagined scenarios, this study expands current research by utilizing actual retrospective reports. It was hypothesized that males would engage in significantly more mate abandonment behaviors after experiencing a physical infidelity, …

Contextual Healing: What To Do About Scandalous Trademarks And Lanham Act 2(A), Megan M. Carpenter

UC Law Journal

Offensive trademarks have come to the forefront of trademark policy and practice in recent years. While it was once true that more attention had been paid to Lanham Act section 2(a) in the pages of law reviews than in the courts, recent cases have focused attention on the ban on registration of offensive marks and the widespread impact of this ban on trademark owners, including a case before the Supreme Court this term. In this Article, I answer the fundamental question: Given the problems previous research has identified, what should be done about the 2(a) bar for scandalous marks? This …

The Define And Punish Clause And The Political Question Doctrine, Lyle D. Kossis

UC Law Journal

The Constitution gives Congress the power to “define and punish . . . Offences against the Law of Nations.” Congress has used this power to enact various criminal statutes that proscribe certain violations of international law. In some cases, criminal defendants argue that these statutes are unconstitutional because Congress has incorrectly defined the law of nations. Federal courts routinely entertain this argument. But the political question doctrine prevents federal courts from resolving a question when the Constitution entrusts the political branches with providing an answer. The Define and Punish Clause gives Congress, not the courts, the power to define the …

The “New Insiders”: Rethinking Independent Directors’ Tenure, Yaron Nili
