The Cost of Worker Misclassification in New York State

[Excerpt] This study uses data based on audits performed by the NYS Department of Labor Unemployment Insurance Division during the four-year period 2002-2005. Audits were performed on firms in certain industries, and data was extrapolated statewide for these industries only, based on given employment information. Using general and specific audits conducted during the four year period 2002-2005, it is estimated that 39,587 New York employers (of about 400,732) in audited industries misclassified workers each year as independent contractors. Of these, approximately 5,880 employers, or 14.9%, were in the construction industry

Philosophy & The Discourse of Economics

'Samuelsonianism' can be used to refer to what is commonly called the neoclassical or mainstream approach to economics. In this paper I argue that it is this approach that is hindered by a rather contracted methodology, one which over-privileges the language of quantification. However, (to the benefit of economists) I argue that this methodology is itself resultant of a broader intellectual movement – what is called modernism. If we look carefully at the history of economics, much of the stringency that plagues the neoclassical approach can be traced to logical-positivism and the scientism of early ‘analytic’ philosophy. Thus, by considering the role that modernism played in philosophy and mapping its impact on economics, I show how this discourse, the hyper-quantified rhetoric of Samuelsonianism, is a relic of outmoded positivism. Consequently, economics could self-improve by seeking heterogeneity in its discourse and broadening its scope of analysis. While this paper is not an exercise in conceptual analysis per se, it does take language and rhetoric as both its point of departure and primary concern

Tied factor analysis for face recognition across large pose differences

Face recognition algorithms perform very unreliably when the pose of the probe face is different from the gallery face: typical feature vectors vary more with pose than with identity. We propose a generative model that creates a one-to-many mapping from an idealized “identity” space to the observed data space. In identity space, the representation for each individual does not vary with pose. We model the measured feature vector as being generated by a pose-contingent linear transformation of the identity variable in the presence of Gaussian noise. We term this model “tied” factor analysis. The choice of linear transformation (factors) depends on the pose, but the loadings are constant (tied) for a given individual. We use the EM algorithm to estimate the linear transformations and the noise parameters from training data. We propose a probabilistic distance metric that allows a full posterior over possible matches to be established. We introduce a novel feature extraction process and investigate recognition performance by using the FERET, XM2VTS, and PIE databases. Recognition performance compares favorably with contemporary approaches

The Status ‘Regularisation’ Programme for Former Mozambican Refugees in South Africa

This paper intends to describe both the formulation and implementation of a programme to ‘regularise’ the legal residence status of a large group of former Mozambican refugees in South Africa and present a brief critique (from a mainly legal perspective) on the implementation of the regularisation programme itself

The rank of the semigroup of transformations stabilising a partition of a finite set

Let $\mathcal{P}$ be a partition of a finite set $X$. We say that a full transformation $f:X\to X$ preserves (or stabilizes) the partition $\mathcal{P}$ if for all $P\in \mathcal{P}$ there exists $Q\in \mathcal{P}$ such that $Pf\subseteq Q$. Let $T(X,\mathcal{P})$ denote the semigroup of all full transformations of $X$ that preserve the partition $\mathcal{P}$. In 2005 Huisheng found an upper bound for the minimum size of the generating sets of $T(X,\mathcal{P})$, when $\mathcal{P}$ is a partition in which all of its parts have the same size. In addition, Huisheng conjectured that his bound was exact. In 2009 the first and last authors used representation theory to completely solve Hisheng's conjecture. The goal of this paper is to solve the much more complex problem of finding the minimum size of the generating sets of $T(X,\mathcal{P})$, when $\mathcal{P}$ is an arbitrary partition. Again we use representation theory to find the minimum number of elements needed to generate the wreath product of finitely many symmetric groups, and then use this result to solve the problem. The paper ends with a number of problems for experts in group and semigroup theories

Gluino decays with heavier scalar superpartners

We compute gluino decay widths in supersymmetric theories with arbitrary flavor and CP violation angles. Our emphasis is on theories with scalar superpartner masses heavier than the gluino such that tree-level two-body decays are not allowed, which is relevant, for example, in split supersymmetry. We compute gluino decay branching fractions in several specific examples and show that it is plausible that the only accessible signal of supersymmetry at the LHC could be four top quarks plus missing energy. We show another example where the only accessible signal for supersymmetry is two gluon jets plus missing energy.Comment: 17 pages, 8 figures.

Holomorphic selection rules, the origin of the mu term, and thermal inflation

When an abelian gauge theory with integer charges is spontaneously broken by the expectation value of a charge Q field, there remains a Z_Q discrete symmetry. In a supersymmetric theory, holomorphy adds additional constraints on the operators that can appear in the effective superpotential. As a result, operators with the same mass dimension but opposite sign charges can have very different coupling strengths. In the present work we characterize the operator hierarchies in the effective theory due to holomorphy, and show that there exist simple relationships between the size of an operator and its mass dimension and charge. Using such holomorphy-induced operator hierarchies, we construct a simple model with a naturally small supersymmetric mu term. This model also provides a concrete realization of late-time thermal inflation, which has the ability to solve the gravitino and moduli problems of weak-scale supersymmetry.Comment: 18 pages, 1 figur
