Outsourcing and Skill Imports: Foreign High-Skilled Workers on H-1B and L-1 Visas in the United States
This 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
The 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
Review of the Multimedia companion to The Middle Palaeolithic site of Combe-Capelle Bas (France), by H. L. Dibble and S. P. McPherron. [CD-ROM]
It is quite ironic that, as an archaeologist concerned with ancient (lithic) technology, I should be so ignorant about recent advances in modern technology, particularly in the field of information technology which is having such a profound effect on the nature of academic disciplines. It was therefore with some trepidation that I undertook to review the CD-Rom companion to a recent publication in Palaeolithic archaeology (Dibble, H. L. and Lenoir, M. 1996), and user-friendliness, I thought, would be the primary criterion on which, for me, the CD would stand or fall
A Synthesis of the Dibble et al. Controlled Experiments into the Mechanics of Lithic Production
Archaeologists have explored a wide range of topics regarding archaeological stone tools and their connection to past human lifeways through experimentation. Controlled experimentation systematically quantifies the empirical relationships among different flaking variables under a controlled and reproducible setting. This approach offers a platform to generate and test hypotheses about the technological decisions of past knappers from the perspective of basic flaking mechanics. Over the past decade, Harold Dibble and colleagues conducted a set of controlled flaking experiments to better understand flake variability using mechanical flaking apparatuses and standardized cores. Results of their studies underscore the dominant impact of exterior platform angle and platform depth on flake size and shape and have led to the synthesis of a flake formation model, namely the EPA-PD model. However, the results also illustrate the complexity of the flake formation process through the influence of other parameters such as core surface morphology and force application. Here we review the work of Dibble and colleagues on controlled flaking experiments by summarizing their findings to date. Our goal is to synthesize what was learned about flake variability from these controlled experiments to better understand the flake formation process. With this paper, we are including all of the data produced by these prior experiments and an explanation of the data in the Supplementary Information

Control and Filtering for Discrete Linear Repetitive Processes with H infty and ell 2--ell infty Performance
Repetitive processes are characterized by a series of sweeps, termed passes, through a set of dynamics defined over a finite duration known as the pass length. On each pass an output, termed the pass profile, is produced which acts as a forcing function on, and hence contributes to, the dynamics of the next pass profile. This can lead to oscillations which increase in amplitude in the pass to pass direction and cannot be controlled by standard control laws. Here we give new results on the design of physically based control laws for the sub-class of so-called discrete linear repetitive processes which arise in applications areas such as iterative learning control. The main contribution is to show how control law design can be undertaken within the framework of a general robust filtering problem with guaranteed levels of performance. In particular, we develop algorithms for the design of an H? and dynamic output feedback controller and filter which guarantees that the resulting controlled (filtering error) process, respectively, is stable along the pass and has prescribed disturbance attenuation performance as measured by and – norms
The late Middle Palaeolithic in Southwest France: New TL dates for the sequence of Pech de l'Azé IV
The relative and numerical chronological position of the technological and typological variants of the Mousterian in southwest France has been the subject of debate for over fifty years. Since the advent of both ESR and TL dating methods in the 1980s, a database of chronometric dates for a growing number of sites has been steadily accumulating. A recent summary by Guibert et al. appears to show a complex pattern of broadly overlapping Mousterian variants in the late Middle Palaeolithic and has led some to conclude that Bordes’ initial interpretation of these variants, as distinct cultural groups, was essentially correct. This paper adds to this database with new thermoluminescence dates from Pech de l’Azé IV. This site, originally excavated by Bordes in the 1970s, contains a deep sequence of Mousterian assemblages, which express considerable technological and typological variability and which are associated with wellpreserved faunal remains. Excavations were undertaken from 2000 to 2003, in part to gain a better understanding of the geological context of the assemblages and also to obtain chronometric data. In this paper, new TL dates for the levels 3B, 4C, 5A and 8 are presented. The deepest of these, the Typical Mousterian of Layer 8, is placed in Marine Isotope Stage (MIS) 5c. Another Typical Mousterian industry from level 5A dates to the transition from MIS 5 to MIS 4. Level 4C, which is rich in scrapers, is placed in MIS 4, while the Mousterian of Acheulian Tradition is attributed to MIS 3. At a local scale, these new dates allow for the integration of the Pech de l’Azé IV sequence with chronometric dates available for the nearby sites of Pech de l’Azé I and II, and at a more regional scale they provide additional data points from the more poorly dated late interglacial and early MIS 4 period. These dates are in line with the emerging pattern suggesting that the Mousterian variants, as they are defined, overlap considerably in time, and call into question their interpretation as a succession of chronological units, while a correlation with climate change of the technological units is not clear either
