Mathematical Modeling of Trending Topics on Twitter

Created in 2006, Twitter is an online social networking service in which users share and read 140-character messages called Tweets. The site has approximately 288 million monthly active users who produce about 500 million Tweets per day. This study applies dynamical and statistical modeling strategies to quantify the spread of information on Twitter. Parameter estimates for the rates of infection and recovery are obtained using Bayesian Markov Chain Monte Carlo (MCMC) methods. The methodological strategy employed is an extension of techniques traditionally used in an epidemiological and biomedical context (particularly in the spread of infectious disease). This study, which addresses information spread, presents case studies pertaining to the prevalence of several “trending” topics on Twitter over time. The study introduces a framework to compare information dynamics on Twitter based on the topical area as well as a framework for the prediction of topic prevalence. Additionally, methodological and results-based comparisons are drawn between the spread of information and the spread of infectious disease

Restoring Bankruptcy’s Fresh Start

The discharge injunction, which allows former debtors to be free from any efforts to collect former debt, is a primary feature of bankruptcy law in the United States. When creditors have systemically violated debtors’ discharge injunctions, some debtors have attempted to challenge those creditors through a class action lawsuit in bankruptcy court. However, the pervasiveness of class-waiving arbitration clauses likely prevents those debtors from disputing discharge injunction violations outside of binding, individual arbitration. This Note first discusses areas of disagreement regarding how former debtors may enforce their discharge injunctions. Then, it examines the types of disputes that allow debtors to collectivize in bankruptcy court. Without seeking to resolve either disagreement, this Note assumes debtors may collectivize in this context and employs an “inherent conflict” test that looks to whether disputes over discharge injunction violations are arbitrable. Because the “inherent conflict” test likely leads to the conclusion that courts must enforce class-waiving arbitration clauses, this Note argues that Congress should amend the Bankruptcy Code not only to provide debtors an express right of action under § 524 and the ability to collectivize, but also to prohibit the arbitration of these claims. Doing so will give full effect to the discharge injunction and fulfill the promise to debtors that they can truly begin anew after bankruptcy

CBA at the PTO

What are the costs and benefits of patent laws? While Congress and the courts are often able to evade this difficult question, there is one institutional actor that is not only well-advised but also required to consider costs and benefits: the Patent and Trademark Office, which—as an administrative agency—is required by executive order to conduct cost-benefit analysis of all economically significant regulations. Yet the agency’s efforts have been less than satisfactory. In its cost-benefit analysis, the PTO overlooks crucial functional considerations, misunderstands basic precepts of patent economics, and resists quantification when quantification is required. In combination, these shortcomings suggest that the PTO has not correctly measured the social costs and benefits of the rules it creates, in part because it has adopted an overly limited view of the welfare effects of intellectual property and the agency’s own role in promoting or discouraging IP. In other instances, the PTO has promulgated rules that will likely have tremendous economic significance without recognizing their importance or conducting a cost-benefit analysis. These errors cast doubt on whether the PTO’s regulations will increase or diminish social welfare. Before the PTO is granted any additional substantive authority, reform will be necessary

Splitting Blacks?: Affirmative Action and Earnings Inequality within and Across Races

Critics have said that affirmative action is at best ineffective and at worst counterproductive. In particular, it has been argued that if affirmative action helps anybody, it helps only the highly educated cream of the minority population, and may perversely work to the detriment of the unskilled and uneducated. This study finds that minority males earn higher wages in sectors where affirmative action is prevalent, indicating that it has increased the demand for minority males. I also find evidence of this effect for both the lowly and highly educated, suggesting that affirmative action under the Executive Order has not contributed to the economic bifurcation of the minority community.
