The paper explores the incidence of over and under education and the effect on earnings for immigrants and natives who hold UK qualifications, drawn from the Quarterly Labour Force Survey 1993-2003. The paper also compares earnings penalties associated with over and under education across immigrant and minority ethnic groups for men and women. The results show that compared to Whites, Black Afr...
Recently, a number of reports have been published on silicosis in workers exposed to artificial quartz conglomerates containing high levels of crystalline silica particles (70-90%) used in the construction of kitchen and bathroom surfaces. Three cases of silicosis in workers exposed to artificial quartz conglomerates are reported. The diagnosis was derived from both the International Labour Off...
There are many possible means of determining job exposure ranging from job Classifications through to self reports of physical exposure to measures of muscle activations and estimated spinal loads.We suggest a fruitful approach is to develop a framework which allows one to combine instruments to take advantage of the best features of each instrument. We suggest that using a common metric allows...
The paper considers generalized maximum likelihood asymptotic power one tests which aim to detect a change point in logistic regression when the alternative specifies that a change occurred in parameters of the model. A guaranteed nonasymptotic upper bound for the significance level of each of the tests is presented. For cases in which the test supports the conclusion that there was a change po...
We present a translation of J. Barwise and J. Seligman’s Information Flow Theory into a lattice and Galois connection based formalism. We show how to transform the different structures of the theory into this formalism and show that this translation extends the expressivity of the theory.
A fundamental problem in music is to classify songs according to their rhythm. A rhythm is represented by a sequence of “Quick” (Q) and “Slow” (S) symbols, which correspond to the (relative) duration of notes, such that S = QQ. In this paper we present a linear algorithm for locating the maximum-length substring of a music text t that can be covered by a given rhythm r. An efficient algorithm t...
The word existence is repeatedly used in arguments in mathematics, and there are several possibilities for the explicit definition of the existence of mathematical objects. Sometimes the word is used in a strict and rigorous sense, but in other occasions, it may have a more moderate meaning. One account of existence says that the existence of a mathematical object is affirmed when the consisten...
Using plant data that distinguish between occupations, tasks, and workforce skills, this paper investigates the relationship between offshoring and the onshore workforce composition at German multinational enterprises (MNEs) in manufacturing and services. There is no statistically significant association between offshoring and the share of whiteand blue-collar jobs in the onshore wage bill. The...
Since the 1980s, the U.S. income distribution has become considerably more concentrated toward the top while the wealth distribution has not. I argue that this can be accounted for by occupational shifts caused by the decline in tax progressivity. To show this, I construct a dynamic general equilibrium model of occupational choice which distinguishes between entrepreneurs, who run their own fir...
