Quantifying the Contours of Power: Chief Justice Roberts & Justice Kennedy in Criminal Justice Cases

This Article seeks to contribute to the debate with an empirical analysis of voting behavior in criminal justice cases decided during the first ten Terms of the Roberts Court era. The following section presents the study’s case selection and introduces the types of measures used to illuminate influence on the High Court (Part II). Court- and individual-level tendencies (Part III) identify potential spheres of influence occupied by Chief Justice Roberts and Justice Kennedy. These bases of judicial power are examined separately in Part IV (Chief Justice Roberts) and Part V (Justice Kennedy). Some possible implications of Justice Scalia’s death on these power bases are addressed in Part VI

Strategies for Imaging Faint Extended Sources in the Near-Infrared

Quantitative information about variations in the background at J and K' are presented and used to develop guidelines for the acquisition and reduction of ground-based images of faint extended sources in the near-infrared, especially those which occupy a significant fraction of the field of view of a detector or which are located in areas crowded with foreground or background sources. Findings are based primarily upon data acquired over three photometric nights with the 3.6x3.6 arcmin CFHT-IR array on the Canada-France-Hawaii Telescope atop Mauna Kea. Although some results are specific to CFHT, overall conclusions should be useful in guiding observing and reduction strategies of extended objects elsewhere.Comment: Accepted for publication in PASP July 2004. 29 pages, including 2 tables and 9 figure

Chief Justice William Rehnquist: His Law-and-Order Legacy and Impact on Criminal Justice

In this article, we explore Chief Justice Rehnquist’s criminal justice decisions through an empirical analysis of the Court’s decision-making tendencies for the most recent natural court and a review of selected criminal justice decisions written by Justice Rehnquist throughout his career. To start, we limit the analysis, with only two exceptions, to decisions actually written by Justice Rehnquist. Although Chief Justice Rehnquist, in that position, had an important role in leading other justices to agree with him by assigning cases, we gleaned a substantial amount of information regarding his decisional patterns and policy preferences by analyzing the opinions he personally authored. The focus of this inquiry, then, is Justice Rehnquist’s actual opinions and not his votes in other cases. This empirical analysis is complemented and given context by a discussion of the overall thrust of criminal justice cases decided by the Court in the last decade...In Section II we provide a brief biographical sketch of Justice Rehnquist’s education and career. We then analyze the criminal justice decisions of the most recent Rehnquist Court using cases from 1995-2005 in Section III. This time frame captures Rehnquist’s last natural court with the exception of the first term. Although Justice Breyer–the last member to join the Court of interest here–served a full term in 1994, we do not include the 1994-1995 Term to avoid the risk that Breyer’s performance (and the Court’s more general decision patterns) might have been distorted by the “freshman effect.” In Section IV we extend the period under review and examine some of Justice Rehnquist’s written opinions, both as an Associate Justice and as Chief Justice. In the final section, we discuss the overall impact of Justice Rehnquist’s decisions on criminal justice issues and revisit the characterization of Rehnquist as central to a “law and order” shift

Evaluation of dissociated and steam-reformed methanol as automotive engine fuels

Dissociated and steam reformed methanol were evaluated as automotive engine fuels. Advantages and disadvantages in using methanol in the reformed rather than liquid state were discussed. Engine dynamometer tests were conducted with a four cylinder, 2.3 liter, spark ignition automotive engine to determine performance and emission characteristics operating on simulated dissociated and steam reformed methanol (2H2 + CO and 3H2 + CO2 respectively), and liquid methanol. Results are presented for engine performance and emissions as functions of equivalence ratio, at various throttle settings and engine speeds. Operation on dissociated and steam reformed methanol was characterized by flashback (violent propagation of a flame into the intake manifold) which limited operation to lower power output than was obtainable using liquid methanol. It was concluded that: an automobile could not be operated solely on dissociated or steam reformed methanol over the entire required power range - a supplementary fuel system or power source would be necessary to attain higher powers; the use of reformed mechanol, compared to liquid methanol, may result in a small improvement in thermal efficiency in the low power range; dissociated methanol is a better fuel than steam reformed methanol for use in a spark ignition engine; and use of dissociated or steam reformed methanol may result in lower exhaust emissions compared to liquid methanol

Long-life mission reliability for outer planet atmospheric entry probes

The results of a literature analysis on the effects of prolonged exposure to deep space environment on the properties of outer planet atmospheric entry probe components are presented. Materials considered included elastomers and plastics, pyrotechnic devices, thermal control components, metal springs and electronic components. The rates of degradation of each component were determined and extrapolation techniques were used to predict the effects of exposure for up to eight years to deep space. Pyrotechnic devices were aged under accelerated conditions to an equivalent of eight years in space and functionally tested. Results of the literature analysis of the selected components and testing of the devices indicated that no severe degradation should be expected during an eight year space mission

Causality-based criteria for a negative refractive index must be used with care

Using the principle of causality as expressed in the Kramers-Kronig relations, we derive a generalized criterion for a negative refractive index that admits imperfect transparency at an observation frequency $\omega$. It also allows us to relate the global properties of the loss (i.e. its frequency response) to its local behaviour at $\omega$. However, causality-based criteria rely the on the group velocity, not the Poynting vector. Since the two are not equivalent, we provide some simple examples to compare the two criteria.Comment: slightly longer version of published PR

Are aerobic fitness and repeated sprint ability linked to fatigue in professional soccer match-play? A pilot study

This investigation examined the association between aerobic fitness and repeated sprint ability and match-related fatigue in 9 professional outfield soccer players. Aerobic fitness using maximal aerobic speed (MAS) was determined via a continuous progressive incremental running test conducted on a motorised treadmill. A repeated sprint ability test (6 successive 6 s sprints separated by 20 s passive recovery) was performed on a non-motorised treadmill to determine mean and best sprint times and a percentage decrement score (%PD). A total of 114 observations of physical performance derived using computerised time motion analyses were collected from 33 matches. Correlations between fitness test and match-play measures were examined for 1) accumulated fatigue: percentage difference between halves for total distance covered per minute, distance run at high-intensities (HIR, actions for 1s duration, >19.1 km/h) per minute, mean recovery time between high-intensity runs, and percentage difference between the distance covered in HIR in the first 5- and 15-minute periods versus the final 5- and 15-minute periods respectively in normal time; and for 2) transient fatigue: percentage difference between the distance covered in HIR in a peak 5-minute period and the subsequent 5-minute period and for the latter compared to the mean for all other 5-minute periods. No significant relationships were observed between MAS and fatigue scores (magnitude of associations: trivial to large). For mean and best sprint times and %PD, the only reported significant correlation (r=0.77, magnitude of association: very large, p<0.05) was between %PD and the % difference across halves for mean recovery time between high-intensity runs (magnitude of other associations: small to large). Criterion measures from tests of aerobic fitness and repeated sprint ability might not accurately depict a player’s capacity to resist fatigue during professional soccer competition
