    The Fox Expedition in Search of Franklin : A Documentary Trail

    A portfolio of contemporary documents relating to the Fox expedition in search of Sir John Franklin has recently been found. It contained 14 personal letters written to Captain F.L. M'Clintock by Lady Jane Franklin and her niece, Sophia Cracroft; newspaper clippings of long letters from explorer John Rae and Allen Young, third officer on the Fox; and a drawing. With one exception, these documents are being introduced to scholars for the first time. Newly discovered is Lady Jane Franklin's offer of command of the Fox to Captain F.L. M'Clintock. The documents, now in the author's possession, affirm Lady Franklin's thoroughgoing nature and tenacity in seeking to uncover information on her lost husband and his crew. Some other themes are the trust (well placed, as it turned out) that she accorded Captain M'Clintock and the distinct favour or disfavour with which she viewed various other Arctic personalities of the era. These themes have been commented upon in the past, but are confirmed by the documents. This article summarizes the content of the documents, places them in historical context, and quotes the two most significant letters in their entirety.On vient de découvrir un dossier de documents contemporains ayant trait à l'expédition Fox qui fut lancée à la recherche de sir John Franklin. Il contient 14 lettres personnelles adressées au capitaine F. L. M'Clintock par lady Jane Franklin et sa nièce, Sophia Cracroft; des coupures de journaux contenant de longues lettres écrites par l'explorateur John Rae et par Allen Young, troisième officier à bord du Fox; et un dessin. À une exception près, c'est la première fois que ces documents font l'objet d'une étude de la part de spécialistes. Un élément inédit est l'offre de commandement du Fox faite par lady Jane Franklin au capitaine F. L. M'Clintock. Les documents, qui sont maintenant entre les mains de l'auteur, affirment le caractère énergique et la ténacité de lady Franklin à vouloir découvrir ce qu'il était advenu de son mari et de l'équipage disparus. D'autres thèmes qui ressortent sont la confiance (bien placée, comme le confirmeront les événements) qu'elle accorda au capitaine M'Clintock et sa façon très nette de considérer d'un bon ou d'un mauvais œil les divers personnages de l'époque ayant affaire avec l'Arctique. Ces thèmes, qui ont déjà fait l'objet de commentaires dans le passé, sont confirmés par les documents. L'article résume le contenu de ces derniers, les replace dans un contexte historique et cite les deux lettres les plus importantes dans leur intégralité

The definitive version was published in Journal of Physical Oceanography 36 (2006): 1305-1316, doi:10.1175/JPO2909.1.Observations of the buoyant coastal current that flows southward from Chesapeake Bay are used to describe how the thickness, width, and propagation speed vary in response to changes in the along-shelf wind stress. Three basic regimes were observed depending on the strength of the wind. For weak wind stresses (from −0.02 to 0.02 Pa), the buoyant coastal current was relatively thin, the front slope was not steep, and the width was variable (1–20 km). For moderate downwelling (southward) wind stresses (0.02–0.07 Pa), wind-driven cross-shelf advection steepened the front, causing the plume to narrow and thicken. For stronger downwelling wind stresses (greater than 0.07 Pa), vertical mixing dominated, bulk Richardson numbers were approximately 0.25, isopycnals were nearly vertical, and the plume front widened but the plume width did not change. Plume thickness and width were normalized by the theoretical plume scales in the absence of wind forcing. Normalized plume thickness increased linearly from 1 to 2 as downwelling wind stresses increased from 0 to 0.2 Pa. Normalized plume widths were approximately 1 for downwelling wind stresses from 0.02 to 0.2 Pa. The observed along-shelf propagation speed of the plume was roughly equal to the sum of the theoretical propagation speed and the wind-driven along-shelf flow.This work was funded by the National Science Foundation under Grants OCE-0095059, OCE-0220773, OCE-92-21614, and OCE-96-33013

    Effects of Systematic Desensitization of Test Anxiety on Cognitive Performance for College Students on Low, Average and High Aptitude

    This study is concerned with the effectiveness of systematic desensitization of test anxiety for heightening cognitive performance of college students. The primary objective is to delineate subject characteristics which interact with the treatment procedures. This would make it possible to specify for what type of student systematic desensitization would be most beneficial.Educational Psycholog

The definitive version was published in Journal of Geophysical Research 117 (2012): C09027, doi:10.1029/2012JC008182.We examine the circulation over the inner-shelf of the Catalan Sea using observations of currents obtained from three Acoustic Doppler Current Profilers (two at 24 m and one at 50 m) during March–April 2011. The along-shelf current fluctuations during that period are mainly controlled by local wind stress on short time scales and by remote pressure gradients on synoptic time scales. Different forcing mechanisms are involved in the along-shelf momentum balance. During storm conditions, wind stress, sea level gradients and the nonlinear terms dominate the balance. During weak wind conditions, the momentum balance is controlled by the pressure gradient, while during periods of moderate wind in the presence of considerable stratification, the balance is established between the Coriolis and wind stress terms. Vertical variations of velocity are affected by the strong observed density gradient. The increased vertical shear is accompanied by the development of stratified conditions due to local heating when the wind is not able to counteract (and break) stratification. The occasional influence of the Besòs River plume is observed in time scales of hours to days in a limited area in near the city of Barcelona. The area affected by the plume depends on the vertical extent of the fresher layer, the fast river discharge peak, and the relaxation of cross-shore velocities after northeast storm events. This contribution provides a first interpretation of the inner-shelf dynamics in the Catalan Sea.The research leading to these results has received funding fromthe European Community’s Seventh Framework Programme (FP7/2007/2013) under grant agreement 242284 (Field_ac project).2013-03-2

    A logical layer to interpret user interactions

    Some computing user interfaces include a large number of user-selectable options which can make it difficult for a user to locate the right option. Another frequent user interface problem is inadvertent or unintended invocation of actions, e.g., by selection of an incorrect icon from two icons placed close to each other. In some user interfaces, simple actions sometimes require a disproportionately tedious sequence of interactions. This disclosure introduces a layer between the user and the application such that user commands or interactions are interpreted in light of past interactions, and corrected, filtered or automated as appropriate. Past interactions are utilized, and interpretation or corrective action is performed only upon permission from the user. For ease of interaction, such permission is obtained, e.g., at initial setup, and is modifiable
