Immigration Policy Demanders: The Influence of U.S. Interests Groups and the American Electorate on Major Political Party Platforms
This Independent Study seeks to understand how political parties create their platforms. Specifically, this study examines how, when, and why political parties cater to the interests of interest groups and the electorate regarding immigration policy. Three qualitative case studies are examined: 1984, 2004, and 2016 party platforms and the corresponding policy preferences of interest groups and the electorate. Bawn et. al’s theory on political parties forms the theoretical framework of this study, which claims that parties are likely to cater to interest groups when political salience is low and parties are likely to cater to the electorate when political salience is high. Ultimately, I find that Bawn et. al’s theory applies well to my case studies. This study provides insight into how parties are motivated to change, especially within the context of immigration
Torturing terrorists for national security imperatives: Mediated violence on 24
This study analyzed mediated violent content as seen on the FOX television program 24. The study covered a seven year period, or six seasons, of 24 , with a sample set of 43 episodes and 445 individual acts ofviolence. Three research questions guided this study. The first research question sought to determine if a relation exists between heroic characters inflicting torturous violence and justifying the act with a national security imperative. The second research question examined the prevailing mode of violence and the use of nonlethal and lethal weapons. The third research question examined the portrayed efficiency of violence on24. Findings suggest that while torture is rarely the intent and rarely justified with a national security imperative, 24 is nonetheless very violent, generally portraying violence as physical, involving the use of lethal weapons, intentionally gratuitous, and most often efficient

The Impact on Maine's Budget of Allowing Same-Sex Couples to Marry
This analysis estimates the impact of allowing same-sex couples to marry on Maine's state budget. We estimate that allowing same-sex couples to marry will result in a net gain of approximately 7.9 million

Subunit assembly modulates the activities of the Type III restriction–modification enzyme PstII in vitro
We demonstrate that, like other Type III restriction endonuclease, PstII does not turnover such that a DNA substrate is only fully cleaved at a Res(2)Mod(2)-to-site ratio of ∼1:1. However, unlike other Type III enzymes, the cleavage rate profiles varied with protein concentration: using 5 nM DNA and 25 nM PstII, approximately half of the DNA was cut at a fast rate while the remainder was cut 24 times more slowly; in comparison, with 100 nM PstII cleavage occurs at a single fast rate. The inclusion of the methyl donor S-adenosyl methionine does not alter the rates with 100 nM PstII but with 25 nM PstII the reaction stopped after completion of the initial fast cleavage phase owing to methylation. Concentration-dependent rates were also observed in methylation assays: at 100 nM PstII, a single slow rate was measured while at lower PstII concentrations both fast and slow rates were measured. We propose a model in which the intact Res(2)Mod(2) complex favoured at high PstII concentrations is a fast endonuclease/slow methyltransferase while the various subassemblies which coexist at lower concentrations are fast methyltransferases. A potential role for disassembly in control of restriction activity in vivo is discussed
Incoherent dynamics in neutron-matter interaction
Coherent and incoherent neutron-matter interaction is studied inside a
recently introduced approach to subdynamics of a macrosystem. The equation
describing the interaction is of the Lindblad type and using the Fermi
pseudopotential we show that the commutator term is an optical potential
leading to well-known relations in neutron optics. The other terms, usually
ignored in optical descriptions and linked to the dynamic structure function of
the medium, give an incoherent contribution to the dynamics, which keeps
diffuse scattering and attenuation of the coherent beam into account, thus
warranting fulfilment of the optical theorem. The relevance of this analysis to
experiments in neutron interferometry is briefly discussed.Comment: 15 pages, revtex, no figures, to appear in Phys. Rev.
