Participation and argument in legislative debate on statewide smoking restrictions
Apollonio, Dorie E; Lopipero, Peggy; Bero, Lisa A
2007-01-01
Background In this paper we review the relationship between participation in legislative hearings, the use of ideological arguments, and the strength of public health legislation using a theoretical construct proposed by E. E. Schattschneider in 1960. Schattschneider argued that the breadth and types of participation in a political discussion could change political outcomes. Methods We test Schattschneider's argument empirically by reviewing the efforts of six states to pass Clean Indoor Air Acts by coding testimony given before legislators, comparing these findings to the different characteristics of each state's political process and the ultimate strength of each state's legislation. Results We find that although greater participation is associated with stronger legislation, there is no clear relationship between the use and type of ideological arguments and eventual outcomes. Conclusion These findings offer validation of a long-standing theory about the importance of political participation, and suggest strategies for public health advocates seeking to establish new legislation.

Recent Social Movements and Theories of Power in America.
ERIC Educational Resources Information Center
McFarland, Andrew S.
A number of propositions about power in America--taken from the work of Olson, Lowi, McConnell, Schattschneider, and Edelman--are presented and discussed. These propositions comprise an alternative theory to pluralism, which is termed "plural elitism." But neither pluralism nor plural elitism explains the emergence and effects of the…

Engineered antibodies for monitoring of polynuclear aromatic hydrocarbons

'The long-term goal of this project is to develop antibodies and antibody-based methods for detection and recovery of polynuclear aromatic hydrocarbons (PAHs) and PAH adducts that are potential biomarkers in environmental and biological samples. The inherent cross-reactivity will be exploited by pattern recognition methods. Dr. Karu''s laboratory uses new haptens representing key PAHs to derive recombinant Fab (rFab) and single-chain Fv (scFv) antibodies from hybridoma lines and combinatorial phage display libraries. Computational models of the haptens and combining sites made by Dr. Roberts''s group are used to guide antibody engineering by mutagenesis. Dr. Li''s laboratory develops enzyme immunoassays (EIAs), sensors,more » and immunoaffinity methods that make use of the novel haptens and antibodies for practical analytical applications in support of DOE''s mission. This report summarizes work completed in one and one-half years of a 3-year project, with close collaboration between the three research groups. Dr. Alexander Karu''s laboratory: the authors proceeded with the two strategies described in the original proposal. Site-directed mutagenesis was used to correct differences in the rFab N-terminal amino acids that were introduced by the degenerate PCR primers used for gene amplification. The binding constants of the rFabs with the corrected sequences will be compared with those of the parent MAbs, and should be very similar. The 4D5 and 10C10 heavy and light chain sequences are being moved to the pCOMB3H phagemid vector to facilitate selection of new engineered mutants.'« less

The short-lived regulated legal market for new psychoactive substances (NPS) in New Zealand marked a radical departure from the traditional prohibition-based approach to drugs. This paper aimed to enhance understanding of this policy change using Punctuated Equilibrium Theory (PET). The analysis draws on 3 years of evaluative research, including interviews with key stakeholders, analysis of legislation and policy documents and academic and grey literature. The reframing of the NPS issue from one of drug control to the need for stricter market regulation was achieved by the efforts of strategic policy entrepreneurs, including the legal high industry, drug law reform advocates, influential politicians and an independent legal advisory institution. This reframing was aided by the perceived saliency of the NPS problem and ineffectiveness of previous prohibition-based responses. In the absence of any political opposition to the regulatory approach, the Psychoactive Substances Act rapidly progressed through the Parliament. However, once the interim legal market was established, portrayal of the issues shifted away from experts and lobbyists to critique from local communities, local government, animal rights activists and the media, who viewed the new regime as a source of social and health problems. The mobilization of criticism ('Schattschneider mobilization') drew on ideas of animal welfare and community safety. With a looming national election, the government responded by ending the interim market with the urgent passage of amendment legislation. Punctuated Equilibrium Theory (PET) helps explain how New Zealand's Psychoactive Substances Act (PSA) policy first emerged on the political agenda and how the initial positive tone of expert support for reform shifted to a tide of popular criticism during the interim regime. However, with its emphasis on explaining agenda-setting, PET does not account for the legislative design shortcomings of the PSA. © 2018 Society for

Investigation on the Characteristics of Pellet Ablation in a Toroidal Plasma

Characteristics of a cloud ablated from an ice pellet has been investigated in detail in the JIPP T-IIU tokamak plasma by utilizing a new scheme of pellet injection system, "the injection-angle controllable system". A long "helical tail" of ablation light has been observed using CCD cameras and a high speed framing photograph in the case of on-axis and off-axis injection with the injection angle smaller than a certain value. The direction of the helical tail is found to be independent to that of the total magnetic field lines of the torus. From the experiments with the combination of two toroildal filed directions and two plasma current directions, it is considered that the tail seems to rotate, in most cases, to the electron diamagnetic direction poloidally, and to the opposite to the plasma current direction toroidally. Consideration on various cross sections including charge exchange, ionization and elastic collisions leads us to the conclusion that the tail-shaped phenomena may come from the situation of charge exchange equilibrium of hydrogen ions and neutrals at extremely high density regime in the cloud. The relation of ablation behavior with plasma potential and rotation has also been studied. Potential measurements of pellet-injected plasmas using heavy ion beam probe (HIBP) method were carried out for the first time. In the case of an injection angle to be anti-parallel to the electron diamagnetic direction in the poloidal plane, the result shows that the direction of potential change is negative, and consequently the potential after the injection should be negative because it has been measured to be negative in usual ohmic plasmas without pellet injection. Thus, the direction of the "tail" structure seems to be consistent to that of the plasma potential measured, if it is considered that tail structure may be caused by the effect of the plasma potential and the rotation.

of ca. 1o x 1o. The REVEALS estimates of the past cover of PFTs will be 1) compared with the outputs of the LPJ-GUESS (10 PFTs), a widely-used dynamic vegetation model and 2) used as an alternative to the LPJ-GUESS-simulated vegetation (3 PFTs) to run for the past the regional climate model RCA3 developed at the Rossby Centre, Norrköping, Sweden. The study will evaluate and further refine these models (RCA3 and LPJ-GUESS) using a data-model comparison approach that incorporates new syntheses of palaeoclimatic data as well. It will lead to new assessments of the possible effect of various factors on climate, such as deforestations and afforestations, and changes in vegetation composition and spatial patterns of land cover/land use. Refined climate models and empirical land-cover reconstructions will shed new light on controversial hypotheses of past climate change and human impacts, such as the "Ruddiman hypothesis". First maps of REVEALS estimates of plant functional types (PFTs) are now available for Sweden, Norway, Finland, Denmark, Estonia, Poland, Germany, The Czech Republic, Switzerland and Britain (see Mazier et al. C1.21 and Trondman et al. C1.22). Correlation tests show that the REVEALS estimates are robust in terms of ranking of the PFTs' abundance (see Mazier et al, C1.21).
