    Scalar Perturbations of two-dimensional Horava-Lifshitz Black Holes

    In this article, we study the stability of black hole solutions found in the context of dilatonic Horava-Lifshitz gravity in 1+11+1 dimensions by means of the quasinormal modes approach. In order to find the corresponding quasinormal modes, we consider the perturbations of massive and massless scalar fields minimally coupled to gravity. In both cases, we found that the quasinormal modes have a discrete spectrum and are completely imaginary, which leads to damping modes. For a massive scalar field and a non-vanishing cosmological constant, our results suggest unstable behaviour for large values of the scalar field mass.Comment: 18 pages, 1 figure.

    Domestic Violence in Rural & Non-Rural Areas: A Study on the Influence of Population Density on Arrest Rates in the State of Florida

    Domestic violence (DV) is a global issue that can affect anyone regardless of what role they play in a family household. It does not discriminate by education, age, religion, etc. DV includes any type of violence or abuse that occurs within a domestic setting. For the purposes of this study, this content primarily focuses on intimate partner violence (IPV) as the main form of DV and is used interchangeably throughout the text. This study examines the influence of population density on arrest rates for DV and some factors behind the likelihood of arrests in urban and rural areas. The literature between both of these societies has demonstrated a clear difference in social behaviors that shape the response to DV (Websdale and Johnson 1998). Normative social influence theory suggests that people\u27s influence may lead someone to conform in order to be liked or accepted by a group (Izuma 2017). This theory hypothesizes that the proportion of people living in rural per county will have fewer arrests for DV than the proportion of people living in non-rural areas because of the need for positive relationships that can lead to conformity (Izuma 2017). Furthermore, it is predicted that there are less arrests in rural areas because of the effects of informal social controls in these areas. Informal social controls can take place between police and citizens that may interact more personally through socialization. An example is when citizens take matters into their own hands, therefore prolonging the reporting of crimes to police. This study uses secondary data provided by sources such as the Florida Department of Law Enforcement (FDLE) website and Social Explorer. Broader implications of this research are that it could shed some light on the social dynamics that impact the outcome of crime in both densely populated and sparsely populated areas

    The Intersection of Intellectual Property and Race in the Twenty-First Century: An Examination of the Interpretation of Racial Categories in Patent Law

    Get PDF
    The political and jurisprudential treatment of racespecific patents, patents on inventions that are aimed at certain racially or ethnically defined groups, in the United States has the potential to legitimize the reification of race and severely impact society\u27s understanding of racial disparities. Accordingly, with the increase in race-specific patents, and race-based technology in general, the way that the courts will construe racial categories in claim terms will determine the pattern and practice of future race relations in the United States. This note examines the role of a judge and an inventor in the potential litigation of a racespecific patent both of whom are in a position to define what we, as a society, understand as race. If judges construe racialized claim terms as a genetic category or as an inherited trait then members of our society will no longer understand racial disparity - such as unemployment rate, educational achievement gap, and the disproportionate representation in the criminal justice system - as a result of a long history of discrimination and injustice. This note, therefore, is not at issue with the commodification of race or the discriminatory implications of the actual granting of exclusive rights to inventors of race-specific patents. Rather, this note finds issue with the impact of the court\u27s construction of racialized claim terms as genetic categories on the future pattern and practice of this society and offers judges a new method of interpretation, intersectionality

    Fire Protection and Life Safety Engineering Analysis- Center for Science and Mathematics

    The Life Safety and Fire Protection systems in Cal Poly’s Center for Science and Mathematics (CSM) were analyzed and evaluated in this project, according to the requirements of the applicable codes and pertinent standards. The evaluation was conducted through a prescriptive-based approach, in conjunction with a performance-based approach. On one hand, the prescriptive-based approach considered the analysis of the Structural Fire Protection and Means of Egress in the building and the existing Fire Detection/Alarm and Fire Suppression Systems. On the other hand, the performance-based approach included an Egress Analysis, which assessed the Required Safe Egress Time (RSET) and the Available Safe Egress Time (ASET) for the occupants to evacuate the building’s atrium safely in the event of a fire. The Egress Analysis was performed using hand calculations and the PATHFINDER computer software, along with data collected from previous studies. The tenability conditions within the building’s atrium were evaluated for different fire scenarios and smoke management alternatives, using the Fire Dynamics Simulator (FDS) software. Finally, some recommendations were appended to improve the performance of the fire safety systems, based upon the outcomes and conclusions obtained in this report
