    Footnote to Furman: Failing Justification for the Capital Case Exception to the Right to Bail after Abolition of the Death Penalty

    Historically, capital crimes were an exception from the right to bail. However, in Furman v. Georgia, the United States Supreme Court abolished this exception. This Comment considers the purpose and constitutional nature of the right to bail to support the Court’s holding in Furman. This Comment asserts that the request for bail in offenses once classified as capital should be resolved in accordance with established standards used in other bail matters. In other words, the accused in a capital crime should possess the same right to bail as an accused in other cases. The constitutional right to bail is implicit in the Eighth Amendment, Due Process, and the Sixth Amendment. The purpose of bail is to permit release of the accused, but at the same time providing a surety or guarantee that the accused will appear at trial. On a theoretical level, bail is used to do much more than provide a guarantee. Bail is used to protect the functioning of the judicial process, to detain those thought to be dangerous, and to protect favored political or cultural interests. However, these uses often lead to an abuse of bail, namely the prevention of bail in capital cases based on the protection of society rationale. However this rationale presupposes the guilt of the accused. Thus, the rationale is contrary to the presumption of innocence that is the foundation of the American justice system. The author concludes that the capital crimes exception to bail is serves no legitimate government interest after Furman

    We used mark-recapture data and population viability analysis (PVA) to estimate demographic parameters, abundance, and harvest risks for two adjacent populations of polar bears (Ursus maritimus) inhabiting Lancaster Sound and Norwegian Bay, Canada. Analyses were based on data from 1871 bears that were uniquely marked during the period 1972–97. Our best-fitting mark-recapture model specified sex and age effects on probabilities of survival and an effect of prior recapture (dependence) on capture probability. The most parsimonious solution in our analysis of survival was to assume the same rate for the Lancaster Sound and Norwegian Bay populations. Total (harvested) annual survival rates (mean ± 1 SE) for females included: 0.749 ± 0.105 (cubs), 0.879 ± 0.050 (ages 1–4), 0.936 ± 0.019 (ages 5– 20), and 0.758 ± 0.054 (ages 21+). Mean litter size was 1.69 ± 0.01 cubs for females of Lancaster Sound and 1.71 ± 0.08 cubs for females of Norwegian Bay. By age six, on average 0.31 ± 0.21 females of Lancaster Sound were producing litters (first age of reproduction was five years); however, females of Norwegian Bay did not reproduce until age seven or more. Total abundance (1995–97) averaged 2541 ± 391 bears in Lancaster Sound and 203 ± 44 bears in Norwegian Bay. The finite rate of increase (lambda) during the study period was estimated to be 1.001 ± 0.013 for bears of Lancaster Sound and 0.981 ± 0.027 for bears of Norwegian Bay. We incorporated demographic parameters into a harvest-explicit PVA to model short-term (15 yr) probabilities of overharvesting (i.e., 1997–2012). Our harvest simulations suggest that current levels of kill are approaching and perhaps exceeding the sustainable yield in both populations.Nous avons recouru aux données obtenues par marquage et recapture ainsi qu’aux analyses de viabilité de population pour estimer les paramètres démographiques, l’abondance et les risques liés à la récolte de deux populations adjacentes d’ours polaires (Ursus maritimus) évoluant dans le détroit de Lancaster et la baie Norwegian, au Canada. Les analyses reposaient sur les données relatives à 1 871 ours marqués de manière unique pendant la période allant de 1972 à 1997. Notre modèle de marquage et recapture le mieux ajusté tenait compte des effets du sexe et de l’âge sur les probabilités de survie, ainsi que de l’effet d’une recapture antérieure (dépendance) sur la probabilité de capture. La solution la plus parcimonieuse de notre analyse de survie consistait à assumer le même taux pour les populations du détroit de Lancaster et de la baie Norwegian. Les taux totaux de survie annuels (récoltés) (moyenne ± 1 SE) chez les femelles s’établissaient comme suit : 0,749 ± 0,105 (oursons), 0,879 ± 0,050 (âges 1-4), 0,936 ± 0,019 (âges 5-20), et 0,758 ± 0,054 (âges 21+). La grosseur moyenne des portées était de 1,69 ± 0,01 ourson dans le cas des femelles du détroit de Lancaster, et de 1,71 ± 0,08 ourson dans le cas des femelles de la baie Norwegian. Avant l’âge de six ans, en moyenne 0,31 ± 0,21 femelle du détroit de Lancaster produisait des portées (l’âge de reproduction le plus jeune était de cinq ans); cependant, les femelles de la baie Norwegian ne se reproduisaient pas avant l’âge de sept ans ou plus. L’abondance totale (1995-1997) atteignait en moyenne 2 541 ± 391 ours au détroit de Lancaster, et 203 ± 44 ours dans la baie Norwegian. Le taux fini d’augmentation (lambda) pendant la période d’étude était estimé à 1,001 ± 0,013 dans le cas des ours du détroit de Lancaster, et de 0,981 ± 0,027 dans le cas des ours de la baie Norwegian. Nous avons intégré les paramètres démographiques à une analyse de viabilité de population de récolte explicite pour modéliser les probabilités à court terme (15 ans) de surrécolte (i.e. 1997-2012). Nos simulations de récolte laissent croire que les taux d’ours tués approchent et peuvent même dépasser le rendement admissible des deux populations

    Determination of yolk contamination in liquid egg white using Raman spectroscopy

    Purified egg white is an important ingredient in a number of baked and confectionary foods because of its foaming properties. However, yolk contamination in amounts as low as 0.01% can impede the foaming ability of egg white. In this study, we used Raman spectroscopy to evaluate the hypothesis that yolk contamination in egg white could be detected based on its molecular optical properties. Yolk contaminated egg white samples (n = 115) with contamination levels ranging from 0% to 0.25% (on weight basis) were prepared. The samples were excited with a 785 nm laser and Raman spectra from 250 to 3,200 cm−1 were recorded. The Raman spectra were baseline corrected using an optimized piecewise cubic interpolation on each spectrum and then normalized with a standard normal variate transformation. Samples were randomly divided into calibration (n = 77) and validation (n = 38) data sets. A partial least squares regression (PLSR) model was developed to predict yolk contamination levels, based on the Raman spectral fingerprint. Raman spectral peaks, in the spectral region of 1,080 and 1,666 cm−1, had the largest influence on detecting yolk contamination in egg white. The PLSR model was able to correctly predict yolk contamination levels with an R2 = 0.90 in the validation data set. These results demonstrate the capability of Raman spectroscopy for detection of yolk contamination at very low levels in egg white and present a strong case for development of an on-line system to be deployed in egg processing plants

    Movements of Subadult Male Grizzly Bears, Ursus arctos, in the Central Canadian Arctic

    Get PDF
    Between May 1995 and June 1999, we equipped eight subadult male (3-5 yrs old) Grizzly Bears (Ursus arctos) with satellite radio-collars within a study area of 235,000 km2, centred 400 km northeast of Yellowknife, Northwest Territories, Canada. Subadult male annual home ranges were extraordinarily large (average = 11,407 km2, SE = 3849) due, in part, to their movement's occasional linear directionality. We believe their long-range linear movements may reflect some individuals tracking the migration of Caribou (Rangifer tarandus). Seasonal daily movement patterns were similar to adult males that were previously reported. The areas used by these bears are the largest ranges reported for any Grizzly Bears and the scale of their movements may put individual bears in contact with humans even when developments are hundreds of kilometres from the central home range of an animal

    Population Viability of Barren-ground Grizzly Bears in Nunavut and the Northwest Territories

    We modelled probabilities of population decline as a function of annual kill for a population of barren-ground grizzly bears (Ursus arctos) inhabiting Nunavut and the Northwest Territories, Canada. Our results suggest that the population is at risk of decline, especially if annual removal rates increase from the 42-year mean of 13.4 bears per year. Adding six bears to the mean annual kill results in a greater than 40% chance of a decrease by one-quarter in population size over the next 50 years, compared to a 10% chance with the current level of human-caused mortality. Additional mortalities may result from increased problem behaviour by bears at mine sites or hunt and exploration camps, given recent increases in human activity in the region, and may already be present as unreported mortality. We believe any increase in current harvest quotas would considerably lessen conservation prospects for the population.On a simulé les probabilités de baisse de la population en fonction du prélèvement annuel dans le cadre de la chasse pour une population de grizzlis de la toundra (Ursus arctos) habitant le Nunavut et les Territoires du Nord-Ouest, au Canada. Nos résultats suggèrent que la population risque de décliner, surtout si les taux de prélèvement augmentent par rapport à la moyenne établie sur 42 ans qui est de 13,4 ours par an. Le fait d'ajouter 6 ours au prélèvement de chasse annuel augmente à plus de 40 % le risque que la population décline d'un quart au cours des prochains 50 ans, par rapport à 10 % dans le cas du niveau actuel de mortalité provoquée par les humains. Vu l'augmentation récente de l'activité anthropique dans la région, d'autres individus pourraient être abattus à cause du nombre croissant de comportements problématiques des ours résidant à des sites miniers et à des campements d'exploration, et il est possible que ce phénomène existe déjà mais que les morts ne soient pas rapportées. Notre opinion est que toute augmentation des quotas actuels de prélèvement réduirait considérablement les perspectives de conservation pour la population

    pp-sdsd shell gap reduction in neutron-rich systems and cross-shell excitations in 20^{20}O

    Excited states in 20^{20}O were populated in the reaction 10^{10}Be(14^{14}C,α\alpha) at Florida State University. Charged particles were detected with a particle telescope consisting of 4 annularly segmented Si surface barrier detectors and γ\gamma radiation was detected with the FSU γ\gamma detector array. Five new states were observed below 6 MeV from the α\alpha-γ\gamma and α\alpha-γ\gamma-γ\gamma coincidence data. Shell model calculations suggest that most of the newly observed states are core-excited 1p-1h excitations across the N=Z=8N = Z = 8 shell gap. Comparisons between experimental data and calculations for the neutron-rich O and F isotopes imply a steady reduction of the pp-sdsd shell gap as neutrons are added
