Outsourcing and Skill Imports: Foreign High-Skilled Workers on H-1B and L-1 Visas in the United States
Full text linkThis 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

Papiliomyces puniceum Z. H. Chen & L. Xu 2023, sp. nov.
No full textPapiliomyces puniceum Z.H. Chen & L. Xu, sp. nov. (Figure 1) MycoBank no.: MB 843059 Etymology: Referring to the puniceus stromata. Stromata arising from the head of the insect buried in soil, clavate, solitary, red, fleshy, 21.5 × 3.9 mm; Fertile part immature. Colonies on PDA medium reaching 36 mm in diameter after 16 days of cultivation at 25 °C, white in early days then turning light red. Hyphae septate, hyaline, smooth-walled, 1.2 – 2.2 (X = 1.7 ± 0.3) µm wide. Phialides smooth-walled, hyaline, a little swollen base, slender top, 7.8 – 16.5 × 1.1 – 1.8 (X = 12.6 ± 3.4 × 1.5 ± 0.2) µm. Conidia echinulate, spherical, immature conidia hyaline and mature conidia slight brown, 3.0 – 5.9 (X = 4.8 ± 0.7) µm. Material examined: CHINA. Yunan Province, the Gaoligong Mountains, On the larva of Hepialidae, 20 May 2017, Zi-Hong Chen (BUM838, holotype; KUNCC 4992, ex-type living culture) Notes: The first visible distinction for morphological feature of P. puniceum from the recognized species in Papiliomyces was that it possessed puniceus stromata (Figure 1). Stromata color of its two sister taxa were quite different, P. shibinense being white to faint yellow, but P. liangshanense being yellow. The second dominant feature that confirmed the uniqueness of P. puniceum was that its conidia shape was spherical, echinulate and its conidia color was slight brown (Figure 1).Published as part of Chen, Zi-Hong, Dai, Yong-Dong, Chen, Kai, Zhang, Yi-Fei, Xu, Ling & Wang, Yuan-Bing, 2023, Papiliomyces puniceum and Metarhizium lymantriidae: two new species from the Gaoligong Mountains in southwestern China, pp. 53-63 in Phytotaxa 594 (1) on page 58, DOI: 10.11646/phytotaxa.594.1.3, http://zenodo.org/record/786889
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

Blind joint maximum likelihood channel estimation and data detection for SIMO systems
No full textA blind adaptive scheme is proposed for joint maximum likelihood (ML) channel estimation and data detection of single-input multiple-output (SIMO) systems. The joint ML optimisation over channel and data is decomposed into an iterative optimisation loop. An efficient global optimisation algorithm called the repeated weighted boosting search is employed at the upper level to optimally identify the unknown SIMO channel model, and the Viterbi algorithm is used at the lower level to produce the maximum likelihood sequence estimation of the unknown data sequence. A simulation example is used to demonstrate the effectiveness of this joint ML optimisation scheme for blind adaptive SIMO systems
Metarhizium lymantriidae Z. H. Chen & L. Xu 2023, sp. nov.
No full textMetarhizium lymantriidae Z.H. Chen & L. Xu, sp. nov. (Figure 2) MycoBank no.: MB 843060 Etymology: Named after the host belonging to the family Lymantriidae (Lepidoptera). Colonies on PDA medium reaching 16 mm in diameter after 16 days of cultivation at 25 °C, white to light green. Hyphae septate, hyaline, branched, smooth-walled, 0.9–1.6 (X = 1.2 ± 0.2) µm wide. Phialides cylindrical or ampuliform, smooth-walled, hyaline, 6.9–21.5 × 0.9–1.5 (X = 10.2 ± 4.6 × 1.2 ± 0.2) µm. Conidia oval or ellipsoidal, forming chain in culture, hyaline, aseptate, smooth, 2.1–3.5 × 1.4–2.1 (X = 2.7 ± 0.2 × 1.7 ± 0.2) µm. Material examined: CHINA. Yunnan Province: the Gaoligong Mountains, on the larva of Lymantriidae, 18 May 2017, Zi-Hong Chen (BUM 818, holotype; KUNCC 4991, ex-type living culture); Baoshan City, on the larva of Lymantriidae, 24 June 2017, Ling Xu (BUM 830, living culture). Notes: Metarhizium lymantriidae was close to M. rileyi and M. dendrolimatilis in the phylogenetic tree. It was difficult to distinguish M. lymantriidae from M. rileyi by the conidia color (Fig. 2 A, B). Isolates of M. lymantriidae grew slowly on PDA medium, similar to M. rileyi. M. dendrolimatilis grew moderately faster than M. lymantriidae and M. rileyi. The distinctiveness of M. lymantriidae was indicated by that its conidia size (2.1–3.5 × 1.4–2.1 µm) was smaller than M. rileyi (3.5–4.5 × 2.0–3.1 µm) and M. dendrolimatilis (3.2–5.4 × 2.2–3.2 µm). The phialides of M. lymantriidae (6.9–21.5 × 0.9–1.5 µm) was more slender than M. rileyi (4.7–6.5 × 2.3–3.0 µm) (Samson 1974) and M. dendrolimatilis (4.3–5.4 × 1.2–3.4 µm). In the wild, M. lymantriidae infected the larva of tussock moth, M. dendrolimatilis infected the larva of Dendrolimus sp., while M. rileyi could infect the larva of noctuid, beetle and sawfly.Published as part of Chen, Zi-Hong, Dai, Yong-Dong, Chen, Kai, Zhang, Yi-Fei, Xu, Ling & Wang, Yuan-Bing, 2023, Papiliomyces puniceum and Metarhizium lymantriidae: two new species from the Gaoligong Mountains in southwestern China, pp. 53-63 in Phytotaxa 594 (1) on pages 59-60, DOI: 10.11646/phytotaxa.594.1.3, http://zenodo.org/record/786889
