Without Consent: Mass-Elite Linkages in Presidential Politics

The transmission of policy preferences from the mass electorate to the political elite is the subject of Warren Miller\u27s illuminating new book. The elites of whom he writes are the delegates to recent nominating conventions analyzed in their subsequent roles as activists involved in presidential election campaigns. Miller\u27s analysis delineates circumstances and conditions that affect the degree to which the issue preferences of these elite activists are more or less representative of those held by rank-and-file members of the nation\u27s electorate. Miller argues that, although consent and accountability are basic principles in the theory of democratic representation, the ways in which convention delegates are selected are not designed to implement these principles. Nevertheless, empirical analysis demonstrates that they often do so to varying degrees. Delegates selected in primary elections, Miller finds, are more representative of the ordinary voters than are delegates selected by any other means—except for Democratic super delegates, who are the most representative of all. Miller\u27s analysis explains why elites who campaign on behalf of particular candidates are less representative of mass policy opinions than are those who campaign on behalf of their parties, and why, ironically, the elites who campaign on behalf of specific policies are even less representative of the issue positions of their parties\u27 rank-and-file partisans. Without Consent, a sequel to Parties in Transition, makes an important contribution to the literature on theories of representation by its novel analysis of linkages connecting public opinion and public policy through the presidential campaign elites. Warren E. Miller is professor of political science at Arizona State University and principal investigator of the National Election Studies at the Institute for Social Research, the University of Michigan. Miller seeks to test the general assumption that party as a guide to voting behavior has weakened; and that elections are normally determined by voters\u27 assessment of the incumbent and policy preference. —American Politics Review It serves as an important contribution to the continually expanding literature on presidential-candidate selection ad end electoral behavior. —The Annals of the American Academyhttps://uknowledge.uky.edu/upk_political_science_american_politics/1033/thumbnail.jp

Air/Sea Transfer of Highly Soluble Gases Over Coastal Waters

The deposition of soluble trace gases to the sea surface is not well studied due to a lack of flux measurements over the ocean. Here we report simultaneous air/sea eddy covariance flux measurements of water vapor, sulfur dioxide (SO2), and momentum from a coastal North Atlantic pier. Gas transfer velocities were on average about 20% lower for SO2 than for H2O. This difference is attributed to the difference in molecular diffusivity between the two molecules (D SO 2/D H 2O = 0.5), in reasonable agreement with bulk parameterizations in air/sea gas models. This study demonstrates that it is possible to observe the effect of molecular diffusivity on air‐side resistance to gas transfer. The slope of observed relationship between gas transfer velocity and friction velocity is slightly smaller than predicted by gas transfer models, possibly due to wind/wave interactions that are unaccounted for in current models

Disinterest, disaffection, and participation in presidential politics

Undue emphasis on the decline of voter turnout in national elections and its interpretation as indicative of political malaise are likely to make for erroneous understanding of the American democracy. Evidence from studies of the national electorate conducted between 1952 and 1978 shows that the explanation for declining turnout is not to be found in commensurate diminution in political interest or involvement, or in a decreasing sense of civic duty, feeling of political efficacy or trust in government. Where patterns of change have coincided, further analysis indicates an absence of possible cause-and-effect relationships. The decline has been chiefly limited to those population sectors characterized by lack of interest or involvement in national partisan politics. The article concludes with a projection of likely developments in political participation, including turnout, in future presidential elections.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/45488/1/11109_2004_Article_BF00989754.pd

Struggling and juggling: a comparison of assessment loads in research and teaching-intensive universities

In spite of the rising tide of metrics in UK higher education, there has been scant attention paid to assessment loads, when evidence demonstrates that heavy demands lead to surface learning. Our study seeks to redress the situation by defining assessment loads and comparing them across research-and teaching intensive universities. We clarify the concept of ‘assessment load’ in response to findings about high volumes of summative assessment on modular degrees. We define assessment load across whole undergraduate degrees, according to four measures: the volume of summative assessment; volume of formative assessment; proportion of examinations to coursework; number of different varieties of assessment. All four factors contribute to the weight of an assessment load, and influence students’ approaches to learning. Our research compares programme assessment data from 73 programmes in 14 UK universities, across two institutional categories. Research-intensives have higher summative assessment loads and a greater proportion of examinations; teaching-intensives have higher varieties of assessment. Formative assessment does not differ significantly across both university groups. These findings pose particular challenges for students in different parts of the sector. Our study questions the wisdom that ‘more’ is always better, proposing that lighter assessment loads may make room for ‘slow’ and deep learning

Relationships between Larval and Juvenile Abundance of Winter-Spawned Fishes in North Carolina, USA

We analyzed the relationships between the larval and juvenile abundances of selected estuarine-dependent fishes that spawn during the winter in continental shelf waters of the U.S. Atlantic coast. Six species were included in the analysis based on their ecological and economic importance and relative abundance in available surveys: spot Leiostomus xanthurus, pinfish Lagodon rhomboides, southern flounder Paralichthys lethostigma, summer flounder Paralichthys dentatus, Atlantic croaker Micropogonias undulatus, and Atlantic menhaden Brevoortia tyrannus. Cross-correlation analysis was used to examine the relationships between the larval and juvenile abundances within species. Tests of synchrony across species were used to find similarities in recruitment dynamics for species with similar winter shelf-spawning life-history strategies. Positive correlations were found between the larval and juvenile abundances for three of the six selected species (spot, pinfish, and southern flounder). These three species have similar geographic ranges that primarily lie south of Cape Hatteras. There were no significant correlations between the larval and juvenile abundances for the other three species (summer flounder, Atlantic croaker, and Atlantic menhaden); we suggest several factors that could account for the lack of a relationship. Synchrony was found among the three southern species within both the larval and juvenile abundance time series. These results provide support for using larval ingress measures as indices of abundance for these and other species with similar geographic ranges and winter shelf-spawning life-history strategies

Renormalization group approach to multiscale modelling in materials science

Dendritic growth, and the formation of material microstructure in general, necessarily involves a wide range of length scales from the atomic up to sample dimensions. The phase field approach of Langer, enhanced by optimal asymptotic methods and adaptive mesh refinement, copes with this range of scales, and provides an effective way to move phase boundaries. However, it fails to preserve memory of the underlying crystallographic anisotropy, and thus is ill-suited for problems involving defects or elasticity. The phase field crystal (PFC) equation-- a conserving analogue of the Hohenberg-Swift equation --is a phase field equation with periodic solutions that represent the atomic density. It can natively model elasticity, the formation of solid phases, and accurately reproduces the nonequilibrium dynamics of phase transitions in real materials. However, the PFC models matter at the atomic scale, rendering it unsuitable for coping with the range of length scales in problems of serious interest. Here, we show that a computationally-efficient multiscale approach to the PFC can be developed systematically by using the renormalization group or equivalent techniques to derive appropriate coarse-grained coupled phase and amplitude equations, which are suitable for solution by adaptive mesh refinement algorithms
