Binational, Multidisciplinary and Evolutionary: Arctic's Tradition and the Future of the Arctic Institute
In its 40 years of continuous quarterly publication, the journal Arctic has traced the intellectual history of Canadian and American northern science as driven by concerns for a variety for northern topics, including political systems, natural resources, military activities, cultural change, sovereignty assertion and natural science. Clearly, the future of northern scholarship deeply involves integrated polar information systems and some kind of centrally recognized polar institute entraining binationalism, a multidisciplinary approach and systematic circumpolar publication. Self-governing, self-reliant and land-owning tribal councils in Alaska, Yukon and the Northwest Territories will provide a further impetus to northern research beyond that already in place for 40 years, based largely upon renewable and non-renewable natural resources. The founding principles of the Institute will serve it well in the context of northern scholarship in the 1990s and 2000s, drawing support from recent Canadian and American evaluations of arctic science policy.Key words: Arctic, Arctic Institute of North America, binationalism, multidisciplinary, northern science, northern scholarship Durant ses 40 ans de publication trimestrielle ininterrompue, le journal Arctic a retracé l'évolution intellectuelle des études canadiennes et américaines sur le Nord. Ces études étaient motivées par des préoccupations qui se rattachaient à divers thèmes du Grand Nord comme le système politique, les ressources naturelles, l'activité militaire, le changement culturel, la question de la souveraineté et les sciences naturelles. Il est clair que l'avenir de la science du Grand Nord repose en très grande partie sur des systèmes d'information polaire intégrés et sur une sorte d'institut polaire centralement reconnu qui favoriserait un bi-nationalisme, une approche multidisciplinaire et des publications recouvrant toute la zone circumpolaire. Les conseils des tribus auto-gouvernées, auto-suffisantes et propriétaires des terres en Alaska, au Yukon et dans les Territoires du Nord-Ouest donneront un nouvel élan à la recherche dans le Grand Nord en plus de celle qui existe depuis 40 ans, à partir surtout des ressources renouvelables et non renouvelables. Les fondements de l'Institut continueront d'être valables dans le contexte des études nordiques durant les années 90 et au-delà, vu qu'ils ont été confirmés par de récentes évaluations faites par le Canada et les États-Unis sur les politiques de l'étude de l'Arctique.

The Disutility of Injustice
For more than half a century, the retributivists and the crime-control instrumentalists have seen themselves as being in an irresolvable conflict. Social science increasingly suggests, however, that this need not be so. Doing justice may be the most effective means of controlling crime. Perhaps partially in recognition of these developments, the American Law Institute\u27s recent amendment to the Model Penal Code\u27s purposes provision â the only amendment to the Model Code in the 47 years since its promulgation â adopts desert as the primary distributive principle for criminal liability and punishment. That shift to desert has prompted concerns by two groups â ironically, two groups traditionally opposed to one another. The first group â those concerned with what they see as the over-punitiveness of current criminal law â worries that setting desert as the dominant distributive principle means continuing the punitive doctrines they find so objectionable, and perhaps will make things worse. The second group â those concerned with ensuring effective crime control â worries that a shift to desert will create many missed crime-control opportunities; it will increase avoidable crime. The first group\u27s concern about over-punitiveness rests upon an assumption that the current punitive crime-control doctrines of which they disapprove are a reflection of the community\u27s naturally punitive intuitions of justice. However, as Study 1 makes clear, today\u27s popular crime-control doctrines in fact seriously conflict with people\u27s intuitions of justice by exaggerating the punishment deserved. The second group\u27s concern that a desert principle will increase avoidable crime exemplifies the common wisdom of the past half century that ignoring justice in pursuit of crime-control through deterrence, incapacitation of the dangerous, and other such coercive crime-control programs is cost free. However, Studies 2 and 3 suggest that doing injustice has real crime control costs. Deviating from the community\u27s shared principles of justice undermines the system\u27s moral credibility and thereby undermines its ability to gain cooperation and compliance and to harness the powerful forces of social influence and internalized norms. The studies reported here give assurance to both groups. A shift to desert is not likely to either undermine the criminal justice system\u27s crime-control effectiveness, and indeed it may enhance it, nor is it likely to increase the system\u27s punitiveness, and indeed it may reduce it
Implicit Self-Importance in an Interpersonal Pronoun Categorization Task
Object relations theories emphasize the manner in which the salience/importance of implicit representations of self and other guide interpersonal functioning. Two studies and a pilot test (total Nâ=â304) sought to model such representations. In dyadic contexts, the self is a âyouâ and the other is a âmeâ, as verified in a pilot test. Study 1 then used a simple categorization task and found evidence for implicit self-importance: The pronoun âyouâ was categorized more quickly and accurately when presented in a larger font size, whereas the pronoun âmeâ was categorized more quickly and accurately when presented in a smaller font size. Study 2 showed that this pattern possesses value in understanding individual differences in interpersonal functioning. As predicted, arrogant people scored higher in implicit self-importance in the paradigm. Findings are discussed from the perspective of dyadic interpersonal dynamics
Black and White as Valence Cues
Replication efforts involving large samples are recommended in helping to determine the reliability of an effect. This approach was taken for a study from Meier, Robinson, and Clore (2004) , one of the first papers in social cognition guided by conceptual metaphor theory, which reported that evaluations were faster when word valence metaphorically matched (e.g., a word with a negative meaning in black) rather than mismatched (e.g., a word with a negative meaning in white) font color. The present investigation was a direct large-scale replication attempt involving 980 participants who completed an experiment using web-based software and were diverse in terms of race, age, and geographical location. Words with a positive meaning were evaluated faster when font color was white rather than black and words with a negative meaning were evaluated faster when font color was black rather than white, replicating the main results of Meier et al. (2004) . </jats:p
The star-formation history of the universe - an infrared perspective
A simple and versatile parameterized approach to the star formation history
allows a quantitative investigation of the constraints from far infrared and
submillimetre counts and background intensity measurements.
The models include four spectral components: infrared cirrus (emission from
interstellar dust), an M82-like starburst, an Arp220-like starburst and an AGN
dust torus. The 60 m luminosity function is determined for each chosen
rate of evolution using the PSCz redshift data for 15000 galaxies. The
proportions of each spectral type as a function of 60 m luminosity are
chosen for consistency with IRAS and SCUBA colour-luminosity relations, and
with the fraction of AGN as a function of luminosity found in 12 m
samples. The luminosity function for each component at any wavelength can then
be calculated from the assumed spectral energy distributions. With assumptions
about the optical seds corresponding to each component and, for the AGN
component, the optical and near infrared counts can be accurately modelled.
A good fit to the observed counts at 0.44, 2.2, 15, 60, 90, 175 and 850
m can be found with pure luminosity evolution in all 3 cosmological models
investigated: = 1, = 0.3 ( = 0), and
= 0.3, = 0.7.
All 3 models also give an acceptable fit to the integrated background
spectrum. Selected predictions of the models, for example redshift
distributions for each component at selected wavelengths and fluxes, are shown.
The total mass-density of stars generated is consistent with that observed,
in all 3 cosmological models.Comment: 20 pages, 25 figures. Accepted for publication in ApJ. Full details

Spontaneous Evolution of Rydberg Atoms into an Ultracold Plasma
We have observed the spontaneous evolution of a dense sample of Rydberg atoms into an ultracold plasma, in spite of the fact that each of the atoms may initially be bound by up to 100 cm21. When the atoms are initially bound by 70 cm21, this evolution occurs when most of the atoms are translationally cold, ,1 mK, but a small fraction, 1%, is at room temperature. Ionizing collisions between hot and cold Rydberg atoms and blackbody photoionization produce an essentially stationary cloud of cold ions, which traps electrons produced later. The trapped electrons rapidly collisionally ionize the remaining cold Rydberg atoms to form a cold plasma
