Outsourcing and Skill Imports: Foreign High-Skilled Workers on H-1B and L-1 Visas in the United States
No full textThis 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
On the Truly Noncooperative Game of Island Life: Introducing a Unified Theory of Value & Evolutionarily Stable Island Economic Development Strategy
No full textThis discourse offers a solution to The Problem of Sustainable Economic Development on islands. This hypothesis offers a foundational, sub-game solution to The Island Survival Game, a counterintuitive, dominant economic development strategy for ‘islands’ (and relatively insular states). This discourse also tables conceptual building blocks, prerequisite analytical tools, and a guiding principle for The Earth Island Survival Game, a bounded delay supergame which models The Problem of Sustainable Economic Development at the global level. We begin our exploration with an introduction to The Principle of Relative Insularity, a postulate which informs ESS for ‘island’ and ‘continental’ players alike. Next, we model ‘island’ economic development with two bio-geo-politico-economic models and respective strategies: The Mustique Co. Development Plan, and The Prince Edward Island Federal-Provincial Program for Social and Economic Advancement. These diametrically opposed strategies offer an extraordinary comparative study. One island serves as a highly descriptive model for The Problem of Sustainable Economic Development; the other model informs ESS. The Island Survival Game serves as a remarkable learning tool, offering lessons which promote Darwinian fitness, resource holding power, self-sufficiency, and cooperative behaviour, by illuminating the illusive path toward sustainable economic development.Non-cooperative games, evolutionary game theory, relative insularity, islands, tragedy of the commons, sustainable economic development, resource holding power, evolutionarily stable strategy, long distance dispersal
On the Problem of Vague Terms: A Glossary of Clearly Stated Assumptions & Careful, Patient, Descriptions
No full textCoase 1930 endures through the decades as one of the most-cited papers in economics due to the fact that it highlights a fundamental and equally enduring problem: "Economic theory has suffered in the past from a failure to state clearly its assumptions. Economists in building up a theory have often omitted to examine the foundations on which it was erected. This examination is, however, essential not only to prevent the misunderstanding and needless controversy which arise from a lack of knowledge of the assumptions on which a theory is based, but also because of the extreme importance for economics of good judgement in choosing between rival sets of assumptions." In 1944 Von Neumann and Morgenstern offered the simply, yet invariably rejected solution: "In… economics the most fruitful work may be that of careful, patient description; indeed this may be by far the largest domain for the present and some time to come….Economic problems [have been and are often] not formulated clearly and are often stated in such vague terms as to make mathematical treatment a priori appear hopeless because it is quite uncertain what the problems really are. There is no point in using exact methods where there is no clarity in the concepts and issues to which they are to be applied. Consequently the initial task is to clarify the knowledge of the matter by further careful descriptive work." This paper offers a stone along the path to the solution to this problem by offering a glossary in this spirit, a glossary germain to some of the most fundamental, open problems in economics. As the fate of the human race may lay in the balance to finding solutions to these problems, this glossary may be a steop in the right direction.economic terms; methodology; scientific method; coase 1930; Von Neumann & Morgenstern 1944; definitions; careful, patient descriptions
Describing quasi-graphic matroids
No full textThe class of quasi-graphic matroids recently introduced by Geelen, Gerards, and Whittle generalises each of the classes of frame matroids and lifted-graphic matroids introduced earlier by Zaslavsky. For each biased graph (G,B) Zaslavsky defined a unique lift matroid L(G,B) and a unique frame matroid F(G,B), each on ground set E(G). We show that in general there may be many quasi-graphic matroids on E(G) and describe them all: for each graph G and partition (B,L,F) of its cycles such that B satisfies the theta property and each cycle in L meets each cycle in F, there is a quasi-graphic matroid M(G,B,L,F) on E(G). Moreover, every quasi-graphic matroid arises in this way. We provide cryptomorphic descriptions in terms of subgraphs corresponding to circuits, cocircuits, independent sets, and bases. Equipped with these descriptions, we prove some results about quasi-graphic matroids. In particular, we provide alternate proofs that do not require 3-connectivity of two results of Geelen, Gerards, and Whittle for 3-connected matroids from their introductory paper: namely, that every quasi-graphic matroid linearly representable over a field is either lifted-graphic or frame, and that if a matroid M has a framework with a loop that is not a loop of M then M is either lifted-graphic or frame. We also provide sufficient conditions for a quasi-graphic matroid to have a unique framework.Zaslavsky has asked for those matroids whose independent sets are contained in the collection of independent sets of F(G,B) while containing those of L(G,B), for some biased graph (G,B). Adding a natural (and necessary) non-degeneracy condition defines a class of matroids, which we call biased-graphic. We show that the class of biased-graphic matroids almost coincides with the class of quasi-graphic matroids: every quasi-graphic matroid is biased-graphic, and if M is a biased-graphic matroid that is not quasi-graphic then M is a 2-sum of a frame matroid with one or more lifted-graphic matroids.Peer reviewedarticleFinal article publishe

Anemometry tools and procedures for greenhouse experiments
No full textGreenhouses provide a useful environment for conducting plant studies, facilitating manipulation and measurement of many variables in the plant microclimate. Photosynthesis, transpiration, thigmomorphogenic responses, and particle transport all depend on the level of air speed at the leaf/atmosphere interface, the microclimate. Yet there seems to exist no standard method of measuring and documenting air velocity in greenhouses.This study was undertaken to determine the airflow parameters for describing the greenhouse microclimate; to investigate anemometer systems best adapted to measurements; to measure airflows in typical greenhouses so that appropriate instruments and procedures might be recommended; and to propose and test a set of measurement procedures for the greenhouse research scientist.Literature review showed a divergence of methodology used in greenhouse versus field crop microclimate studies. Greenhouse research literature predominately used single-leaf models, while atmospheric boundary layer research developed whole-canopy models. An integration of the two approaches is needed so that an entire experimental area in a greenhouse can be characterized with a few key air speed measurements.The greenhouse measurements pointed out the inappropriateness of certain anemometer systems, particularly those which have a markedly directional response. Three research anemometers and three hand-held commercial grade anemometers were evaluated. Most of the kinetic energy in the turbulence spectra was contained in frequencies of less than 5 Hz. Omnidirectional anemometers were shown to be sufficient and convenient for assessing mean velocities over the plant canopies. However, the highly turbulent conditions within the plant canopy may be better studied with tools other than heated element anemometers.Each of the greenhouse rooms measured showed a range of microclimate air velocity means of at least seven to one, except for a commercial fan-tube ventilated greenhouse which had a range of only 2.4 to one. The broad range of means emphasized the need for documentation of air speeds during experiments.Profiles of air speed over the plant canopies showed that the proposed standardized measurement height over the canopy can give meaningful data. A grid system was tested and shown useful in representing rectangular experimental areas of various sizes.Made available in DSpace on 2011-05-07T12:26:22Z (GMT). No. of bitstreams: 2

Scientific Management as Applied to the Personnel Department
No full textIt is the intention of the author to offer in this thesis a new point of view in dealing wit~ men in industry. Modern executives are coming ·to realize that their workers are not a ·bulk mass but a group of individuals. They are recognizing, that these workers differ in things they are fitted to do and are capable of doing; also that they differ in their interests, ambitions, and the thing that seem most desirable; and as men of differing capacities and desires they require individual adjustment to the opportunities offered them in the field of industry
The invisible artist: Arrangers in popular music (1950-2000): Their contribution and techniques
No full textThis thesis was submitted for the degree of Doctor of Philosophy and was awarded by Brunel University.This thesis is based on the research conducted by the author for the series,
Richard Niles' History of Pop Arranging, seven thirty-minute documentary
programmes for BBC Radio 2, researched, written and presented by the author and
broadcast in 2003. It also draws on interviews conducted by the author (and other
research) between 2002 and 2007 both for the radio series and for this thesis and on
the author's experience as a professional arranger in popular music working with
many of the genre's significant recording artists including Paul McCartney, Ray
Charles, Cher, Tina Turner, Westlife, Tears For Fears, Dusty Springfield, James
Brown, Pet Shop Boys, Kylie Minogue and producers including Trevor Hom, Steve
Lipson, Steve Mac and Steve Anderson.
It will be argued that the role of the arranger in popular music has often been
undervalued and that during a critical period of popular music history (1950-2000)
arrangers played a significant part in the evolution of musical content. This thesis is,
to the best of the author's knowledge, the first time (apart from the above mentioned
documentary) the subject has ever been examined. The arranger is "invisible" because musical arrangers are often un-credited on
record liner notes or in books or articles concerning popular music. A considerable
amount of research has been necessary to determine who wrote many of the
arrangements considered herein. Motown's Berry Gordy purposely kept the names of
musicians and arrangers off the records because he feared others might 'poach' the
trademark 'Motown Sound'. Other record labels considered the job of the arranger to
be reminiscent of an earlier era, diluting the Rock 'n' Roll image of emotion and
spontanaeity they wished to promote. Some producers and recording artists disliked
sharing credit for their work. Motown arranger David Van dePitte told the author that
arranging was "thankless and anonymous - a very service-oriented profession where
others often take credit for what you've done." Arranging has therefore remained an
intrinsically unseen art created by 'invisible' artists. By analyzing many recordings,
revealing the techniques and concepts they have used in their work to create popular
records, arrangers and their art will be made more 'visible'
