Methodology for Adjusting GPRA Workforce Development Program Performance Targets for the Effects of Business Cycles

The U.S. Department of Labor’s Employment and Training Administration issued Training and Employment Guidance Letter (TEGL) 09-08 Change 1 on June 5, 2009. This guidance letter revises the Government Performance and Results Act (GPRA) performance measures for federal workforce development programs to take into account the effect of the recession on participants’ labor market and educational outcomes. As described in the TEGL, the performance targets of the various workforce development programs have been developed for use for the years PY2008 through PY2010. They are intended to be used for PY2009 performance target negotiations and will appear in the President’s Budget Request for FY2010. The performance targets for future program years, adjusted for unemployment rates, are driven by the economic assumptions of the President’s Budget Request for FY2010. The revised performance targets are based on analysis carried out as part of a study conducted for the U.S. Department of Labor by the W. E. Upjohn Institute for Employment Research. This working paper has two purposes. The first is to describe the methodology used to estimate the relationship between unemployment rates and workforce program performance targets. The second is to describe the procedures used to adjust the GPRA performance targets for changes in unemployment rates during the current recession and over the business cycle. The study described in this working paper is the initial phase of an ongoing analysis of the effect of economic conditions on workforce development program outcomes.performance standards, workforce programs, GPRA

Influence of oxygen vacancy on the electronic structure of HfO2_2 film

We investigated the unoccupied part of the electronic structure of the oxygen-deficient hafnium oxide (HfO$_{\sim1.8}$) using soft x-ray absorption spectroscopy at O $K$ and Hf $N_3$ edges. Band-tail states beneath the unoccupied Hf 5$d$ band are observed in the O $K$-edge spectra; combined with ultraviolet photoemission spectrum, this indicates the non-negligible occupation of Hf 5$d$ state. However, Hf $N_3$-edge magnetic circular dichroism spectrum reveals the absence of a long-range ferromagnetic spin order in the oxide. Thus the small amount of $d$ electron gained by the vacancy formation does not show inter-site correlation, contrary to a recent report [M. Venkatesan {\it et al.}, Nature {\bf 430}, 630 (2004)].Comment: 5 pages, 4 figures, submitted to Phys. Rev.

Putative spin liquid in the triangle-based iridate Ba3_3IrTi2_2O9_9

We report on thermodynamic, magnetization, and muon spin relaxation measurements of the strong spin-orbit coupled iridate Ba$_3$IrTi$_2$O$_9$, which constitutes a new frustration motif made up a mixture of edge- and corner-sharing triangles. In spite of strong antiferromagnetic exchange interaction of the order of 100~K, we find no hint for long-range magnetic order down to 23 mK. The magnetic specific heat data unveil the $T$-linear and -squared dependences at low temperatures below 1~K. At the respective temperatures, the zero-field muon spin relaxation features a persistent spin dynamics, indicative of unconventional low-energy excitations. A comparison to the $4d$ isostructural compound Ba$_3$RuTi$_2$O$_9$ suggests that a concerted interplay of compass-like magnetic interactions and frustrated geometry promotes a dynamically fluctuating state in a triangle-based iridate.Comment: Physical Review B accepte

Photoproduction off the nucleon revisited: Evidence for a narrow N(1688) resonance?

Revised analysis of $\Sigma$ beam asymmetry for the $\eta$ photoproduction on the free proton reveals a structure at $W\sim 1.69$ GeV. Fit of the experimental data based on the E429 solution of the SAID partial wave analysis suggests a narrow ($\Gamma \leq 25$ MeV) resonance. Possible candidates are $P_{11}, P_{13}$, or $D_{13}$ resonances. The result is considered in conjunction with the recent evidence for a bump-like structure at $W\sim 1.67 - 1.68$ GeV in the quasi-free $\eta$ photoproduction on the neutron.Comment: Contribution to the Workshop on the Physics of the Excited Nucleons NSTAR2007, Bonn, Germany, Sept. 5 - 8 2007.

Downstream Migrations of Juvenile Salmon and Other Fishes in the Upper Yukon River

The Yukon River is the fourth largest river in North America, yet the ecology of its fishes has not been well described. During the spring and summer of 2002– 04, we sampled the downstream migrations of fishes in the Yukon River mainstem near the Canada-U.S. border, using a rotary auger trap. Age-0 juvenile chinook salmon, Oncorhynchus tshawytscha, were the most common fish in the catch, and they peaked in abundance in mid-June. Smaller numbers of age-1 chinook salmon and age-0 chum salmon, O. keta, were caught earlier in the season. Over 80% of the remaining catch consisted of young-of-theyear Coregoninae (whitefish), presumably moving from natal areas to summer rearing habitats. Few adult whitefish were captured, probably because our sampling terminated before fall spawning migrations began. Both juveniles and adults were captured for six other winter or spring spawning species that we encountered. Our results indicate that the Yukon River mainstem is used extensively as a migration corridor. This reach of the mainstem has very high suspended sediment levels in summer; its significance as rearing habitat remains unknown. Further studies are required to delineate the extent of migrations and the population structure for the non-anadromous species.Le fleuve Yukon est le quatrième plus grand fleuve de l’Amérique du Nord et pourtant, l’écologie de ses poissons n’a pas été bien décrite. Au printemps et à l’été des années 2002 à 2004, nous avons échantillonné les migrations en aval des poissons du cours principal du fleuve Yukon, près de la frontière canado-américaine et ce, à l’aide d’un piège rotatif. Le saumon quinnat d’âge 0-juvénile, Oncorhynchus tshawytscha, était le poisson le plus souvent capturé, et son abondance était à son meilleur à la mi-juin. De plus petits nombres de saumon quinnat d’âge 1 et de saumon kéta d’âge 0, O. keta, ont été attrapés au début de la saison. Plus de 80 % du reste des poissons capturés consistait en des Coregoninae (ciscos) jeunes de l’année, qui étaient sans doute en voie de déplacement, passant de leur secteur natal aux habitats d’élevage d’été. Peu de ciscos adultes ont été capturés, probablement parce que notre échantillonnage a pris fin avant les migrations de reproduction d’automne. Des poissons juvéniles et adultes ont été attrapés dans le cas de six autres espèces de reproduction d’hiver ou de printemps que nous avons rencontrées. Nos résultats indiquent que le cours principal du fleuve Yukon sert énormément de corridor de migration. Dans cette partie du cours principal, les taux de sédiments en suspension sont très élevés l’été; son importance en tant qu’habitat d’élevage demeure inconnue. Des études plus poussées s’imposent dans le but de délimiter l’étendue des migrations et la structure de population des espèces non anadromes

Hysteresis and the dynamic phase transition in thin ferromagnetic films

Hysteresis and the non-equilibrium dynamic phase transition in thin magnetic films subject to an oscillatory external field have been studied by Monte Carlo simulation. The model under investigation is a classical Heisenberg spin system with a bilinear exchange anisotropy in a planar thin film geometry with competing surface fields. The film exhibits a non-equilibrium phase transition between dynamically ordered and dynamically disordered phases characterized by a critical temperature Tcd, whose location of is determined by the amplitude H0 and frequency w of the applied oscillatory field. In the presence of competing surface fields the critical temperature of the ferromagnetic-paramagnetic transition for the film is suppressed from the bulk system value, Tc, to the interface localization-delocalization temperature Tci. The simulations show that in general Tcd < Tci for the model film. The profile of the time-dependent layer magnetization across the film shows that the dynamically ordered and dynamically disordered phases coexist within the film for T < Tcd. In the presence of competing surface fields, the dynamically ordered phase is localized at one surface of the film.Comment: PDF file, 21 pages including 8 figure pages; added references,typos added; to be published in PR
