Productivity and Labour Demand Effects of Inward and Outward FDI on UK Industry

We relate the technological and factor price determinants of inward and outward FDI to its potential productivity and labour market effects on both host and home economies. This allows us to distinguish clearly between technology sourcing and technology exploiting FDI, and to identify FDI which is linked to labour cost differentials. We then empirically examine the effects of different types of FDI into and out of the United Kingdom on domestic (i.e. UK) productivity and on the demand for skilled and unskilled labour at the industry level. Inward investment into the UK comes overwhelmingly from sectors and countries which have a technological advantage over the corresponding UK sector. Outward FDI shows a quite different pattern, dominated by investment into foreign sectors which have lower unit labour costs than the UK. We find that different types of FDI have markedly different productivity and labour demand effects, which may in part explain the lack of consensus in the empirical literature on the effects of FDI. Our results also highlight the difficulty for policy makers of simultaneously improving employment and domestic productivity through FDI

Spin structure of spin-1/2 baryon and spinless meson production amplitudes in photo and hadronic reactions

The most general spin structures of the spin-1/2 baryon and spinless meson production operator for both photon and nucleon induced reactions are derived from the partial-wave expansions of these reaction amplitudes. The present method provides the coefficients multiplying each spin operator in terms of the partial-wave matrix elements. The result should be useful in studies of these reactions based on partial-wave analyses, especially, when spin observables are considered.Comment: RevTex 34 pages, revised versio

Plasma tests of sprayed coatings for rocket thrust chambers

Several plasma-sprayed coating systems were evaluated for structural stability in hydrogen plasma and in oxygen plasma mixed with hydrogen plasma. The principal test heat flux was 15 Btu per inch squared seconds. The system consisted of a number of thin 0.002 to 0.020 in. layers of metal oxides and/or metals. The principal materials included are molybdenum nichrome, alumina, and zirconia. The study identifies important factors in coating system fabrication and describes the durability of the coating systems in the test environments. Values of effective thermal conductivity for some of the systems are indicated

Differance and paranoia

This exploratory essay aims to open différance to a form of enquiry it has not seen coming. A consideration of the complex temporality that attends its historical emergence leads to a specifically différantial articulation of spatio-temporality. A residual element of spacing before/behind spatiotemporality provokes further consideration. The notion of verbality is introduced to provide analytical purchase. Analysis identifies a fundamental mannerism in différance; a participative and orchestrative spacance. Différance participates too determinately in this spacing, as this spacing. The paper thus urges différance to rewrite this element quasimetaphorically. In the ensuing drama, différance can rewrite the metaphor of spacing only by relying again on the spacing of metaphor. Unable to rewrite itself quickly enough, nonetheless compelled, an unexpected dimension opens

The Petrographic Analysis of Sherds from the Musgano Site (41RK19), Rusk County, Texas

Characterizing the mineralogical composition of ceramic vessels and sherds from Caddo sites in East Texas by means of petrographic analysis provides a unique opportunity to gather and investigate empirical evidence from ceramic vessels on: (1) technological and manufacturing practices, and (2) their trade and exchange at varying scales conducted by ancestral Caddo people with their neighbors, both near and far (i.e., other ancestral Caddo groups as well as non-Caddo communities). This evidence in turn can be used to explore changes in the nature of social and economic relationships between particular Caddo groups and other prehistoric populations. Identified compositional and paste differences that have been recognized between the different wares made by Caddo groups (i.e., plain wares, utility wares, and fine wares) can also be employed to explore functional and technological differences in vessel function and form. It is important to build on existing petrographic studies of Caddo vessels and vessel sherds by examining unstudied assemblages to (1) better clarify the compositional nature of these ceramic wares across the Caddo temporal and geographic landscape; (2) to help pinpoint other ceramic manufacturing locales and mineralogical compositional groups, but also to assess their apparent technological complexity; and (3) lead to better evaluations of the regional character of prehistoric and historic Caddo trade and interaction networks that existed, and more definitively establish whether there were changes through time in the direction and intensity of local and long distance trade and interaction. The disparate pieces of information contained within the sherds and vessel fragments of Caddo ceramics found on many prehistoric and early historic sites throughout the region have the potential to address these questions and research issues, and can contribute unique information concerning those relationships that existed in the distant (and not-so-distant) past between Caddo farmers. Twenty decorated sherds from the Musgano ceramic assemblage curated at the Texas Archeological Research Laboratory at The University of Texas at Austin (TARL) were selected for petrographic analysis. The sherds were split and one of the remaining fragments of each pair was used for the production of thin sections. Originally, the other half of each sherd was to be submitted for instrumental neutron activation analysis, but such analyses were not done; the remaining sherd fragment was returned for continued curation at TARL. Upon the receipt of the thin sections, they underwent petrographic analysis as reported on herein. The 20 sherds include sherds from engraved fine wares (n=8, 40 percent)—bottles and carinated bowls— as well as sherds from utility wares (n=12, 60 percent). The utility wares have brushed-appliqued, incised, incised-punctated (from Maydelle Incised, Weches Fingernail Impressed, and Washington Square Paneled vessels), and punctated decorative elements. Ten percent of the sherds are from bone-tempered vessels, based on macroscopic examination, while the others are from grog-tempered vessels

Recent experiences using finite-element-based structural optimization

Structural optimization has been available to the structural analysis community as a tool for many years. The popular use of displacement method finite-element techniques to analyze linearly elastic structures has resulted in an ability to calculate the weight and constraint gradients inexpensively for numerical optimization of structures. Here, recent experiences in the investigation and use of structural optimization are discussed. In particular, experience with the commercially available ADS/NASOPT code is addressed. An overview of the ADS/NASOPT procedure and how it was implemented is given. Two example problems are also discussed

Enforcing Competition Through Government Contract Claims

One of the principal objectives of Congress in enacting laws to govern federal government contract awards is to insure competition by maximizing the number of contractors who compete for these contracts. To insure full and open competition, the specifications in government contracts must permit all responsible sources of goods, services, and construction to compete for the work. Specifications which are drawn so that only one source or a very limited number of sources can compete for the work may effectively thwart competition. Whether and how to enforce this requirement for competitive specifications during contract performance is this article\u27s subject

A Comparison of the Coating Properties of Domestic Clays to English Clays

Objective The objective of this thesis was to compare the coating properties of the English and domestic clays. Specifically, it was intended to note which set of clays excelled, if either, in the various properties tested. Furthermore, it would be observed from the results in which properties the primary clays (English) and the secondary clays (domestic) were in close agreement. The experimental work was designed to eliminate as many variables as possible with the exception of the type of clay used
