Congruence curves of the Goldstein-Petrich flows
Get PDFWe study the existence of contours which evolve retaining their shapes under the second Goldstein-Petrich flow. We present a proof of the existence, for each integer n >= 2, of a 1-parameter family of non-congruent Goldstein-Petrich contours of R(2) with symmetry group of order n. Explicit algorithms to compute and visualize the contours and their evolution are give
Outsourcing and Skill Imports: Foreign High-Skilled Workers on H-1B and L-1 Visas in the United States
Get PDFThis working paper looks in detail at the H-1B and L-1 visa programs for temporary employment in the United States. Based on official data from the US Citizenship and Immigration Services and the US Department of State, H-1B and L-1 visa issuance rapidly increased in the late 1990s, followed by a marked slowdown after 2001. This points to the highly cyclical nature of both visa programs. Indian nationals and immigrants working in computer-related occupations dominate the H1-B and L-1 population in the United States, but these two groups are also found to be the most cyclical segment, with very large declines in inflows after 2001. The total population of H-1B visaholders in 2003 is estimated to range between 387,000 and 746,000, of which 160,000 to 306,000 were Indian nationals. As all data on H-1B/L-1 visaholders are gross numbers and gross jobs data for comparable categories are absent, the extent of the impact of these visa programs on the US labor market cannot be gauged precisely. A broad range of US industries and educational institutions are found to be employing H-1B recipients, with the IT industry being the dominant sector. Evidence of aggressive wage-cost cutting, including paying H-1B recipients only the legally mandated 95 percent of the prevailing US wage, is found among some H-1B employers, although no systematic abuse of the system is present.Outsourcing, offshoring, high-skilled labor, immigration, H1B/L-1 visas

Forecast of July 2015—New Jersey: prospects for the long term
No full textThe July 2015 R/ECON forecast shows more rapid growth for the state in 2015 than in 2014. Nonagricultural employment rose by 0.7 percent—or 27,700 jobs in 2014—after growth of 1.2 percent or 45,100 jobs in 2013. Growth will improve to 1.1 percent in 2015 and 2016 and then average 0.8 percent over the rest of the forecast period, which goes through 2045. At these rates the job base will return to the peak level reached in the first quarter of 2008 in mid-2017. By the end of the forecast period in 2045 the employment base will be nearly a million jobs, and 23 percent, greater than its level at the peak.1 These projections assume no specific recession/recovery cycle disrupts the state’s or nation’s growth. Although this seems rather far-fetched given that the average business cycle (peak to peak) in the U.S. since World War II has lasted about 24 quarters and the current cycle is now in its seventh year, a caveat to keep in mind is that this is a long term TREND forecast; it does not purport to indicate at what point(s) CYCLES may occur.Rutgers Economic Advisory Service (R/ECON) quarterly repor
Coupling of caged molecule dynamics to Johari-Goldstein β-relaxation in metallic glasses
Get PDFThree recently published papers have discovered a general property of the fast caged dynamics observed in the glassy states of polyalcohols (S. Capaccioli et al., J. Phys. Chem. B 119, 8800 (2015)), amorphous polymers (K. L. Ngai et al., J. Phys. Chem. B 119, 12502 (2015)), and van der Waals molecular glass-formers (K. L. Ngai et al., J. Phys. Chem. B 119, 12519 (2015)). The fast caged dynamics are manifested as nearly constant loss (NCL) in dielectric and mechanical susceptibility. Shown before in these papers is the intensity of the caged dynamics change temperature dependence at a temperature THF nearly coincident with the secondary glass transition temperature Tgβ, at which the Johari-Goldstein (JG) β-relaxation time τJG reaches ∼103s. Evidently this finding indicates the coupling of the caged dynamics to the secondary glass transition. The glass-formers considered so far are all soft matters. However, the generality of the phenomenon and its explanation implies that the relation, THF - Tgβ, should be observed in other classes of glass-formers. In this paper, we extend the consideration of the phenomenon and explanation to metallic glasses, which are not soft matter. The experimental data presented show the same phenomenon, supporting its generality and fundamental importance in the physics of glass and glass transition
Parseval-Goldstein type identities involving the L-4-transform and the P-4-transform and their applications
No full textIn the present article the authors introduce several new integral transforms including the L-4-transform and the P-4-transform as generalizations of the classical Laplace transform and the classical Stieltjes transform, respectively. It is shown that the second iterate of the L-4-transform is essentially the P-4-transform. Using this relationship, a number of new Parseval-Goldstein type identities are obtained for these and many other well-known integral transforms. The identities proven in this article give rise to useful corollaries for evaluating infinite integrals of special functions. Some examples are also given as illustrations of the results presented here
Knowing color terms enhances recognition: Further evidence from English and Himba
No full textTwo experiments attempted to reconcile discrepant recent findings relating to children’s color naming and categorization. In a replication of Franklin and colleagues (Journal of Experimental Child Psychology, 90 (2005) 114–141), Experiment 1 tested English toddlers’ naming and memory for blue–green and blue–purple colors. It also found advantages for between-category presentations that could be interpreted as support for universal color categories. However, a different definition of knowing color terms led to quite different conclusions in line with the Whorfian view of Roberson and colleagues (Journal of Experimental Psychology: General, 133 (2004) 554–571). Categorical perception in recognition memory was now found only for children with a fuller understanding of the relevant terms. It was concluded that color naming can both underestimate and overestimate toddlers’ knowledge of color terms. Experiment 2 replicated the between-category recognition superiority found in Himba children by Franklin and colleagues for the blue–purple range. But Himba children, whose language does not have separate terms for green and blue, did not show a cross-category advantage for that set; rather, they behaved like English children who did not know their color terms
