Smuggled Sound: Bootleg Recording and the Pursuit of Popular Memory

This paper explores the meanings that bootleg recording holds in peoples’ lives. “Bootlegging” refers to the practice of making unauthorized recordings of live performances. Our paper is an interpretive analysis of interviews with bootleg producers and collectors. In their accounts, they suggest how their activities offer an extraordinary example of what it means to participate in contemporary popular culture. As bootleggers smuggle tape recorders into concerts, or trade tapes in underground networks, they pursue rare artifacts of popular culture. Their stories of bootleg taping, collecting and trading suggest an alternative to depictions of popular culture as merely a process of production and consumption. Instead, these accounts demonstrate how some people document their participation in mass cultural events on their own terms and for their own uses. Here, bootlegging is seen as an attempt by people to capture live performances, to collect them as a source of memory and authenticity, and to mediate the events of their lives through means of technological reproduction.     

Optimal Change-point Estimation in Inverse Problems

We develop a method of estimating a change-point of an otherwise smooth function in the case of indirect noisy observations. As two paradigms we consider deconvolution and non-parametric errors-in-variables regression. In a similar manner to well-established methods for estimating change-points in non-parametric regression, we look essentially at the difference of one-sided kernel estimators. Because of the indirect nature of the observations we employ deconvoluting kernels. We obtain an estimate of the change-point by the extremal point of the differences between these two-sided kernel estimators. We derive rates of convergence for this estimator. They depend on the degree of ill-posedness of the problem, which derives from the smoothness of the error density. Analysing the Hellinger modulus of continuity of the problem we show that these rates are minimax     

On geometry of the set of admissible invariant quadratic estimators in balanced two variance components model

Two variance components model for which each invariant quadratic admissible estimator of a linear function of variance components (under quadratic loss function) is a linear combination of two quadratic forms,Z ₁,Z ₂, say, is considered. A setD={(d ₁,d ₂)′:d ₁ Z ₁+d ₂ Z ₂ is admissible} is described by giving formulae on the boundary ofD. Different forms of the setD are presented on figures.     

Teaching Wealth Distribution in High School

This article presents detailed instructional plans for a two-day, high school-level lesson on wealth distribution in society. The terms income and wealth are defined and compared, and the significance of studying wealth is discussed. Resources for the lesson are identified, and a pedagogical mode is outlined in relation to democratic citizenship education.     

Problems related to confidence intervals for impulse responses of autoregressive processes

Confidence intervals for impulse responses computed from autoregressive processes are considered. A detailed analysis of the methods in current use shows that they are not very reliable in some cases. In particular, there are theoretical reasons for them to have actual coverage probabilities which deviate considerably from the nominal level in some situations of practical importance. For a simple case alternative bootstrap methods are proposed which provide correct results asymptotically.     

Computational and statistical efficiency of semiparametric gls estimators

In this note, we report a dramatic improvement in the computational efficiency of semiparametric generalized least squares(SGLS) estimation. Computation of SGLS estimates no longer presents serious problems with data sets of moderate size. We also correct a numerical error in the standard errors of the SGLS estimates reported in our recent paper in this journal (Horowitz and Neumann, 1987). The corrected standard errors of SGLS are comparable to those we reported for quantile estimates.     

The rights of the child enabling community development to contribute to a valid social work practice with children at risk

This paper presents a way of thinking about and doing child protection work using community development (CD) principles to guide practice. It suggests that a useful addition to CD can be found within the rights of the child provisions in Human Rights conventions. Using examples from the authors' three countries to illustrate the work that practitioners do in their work with children at risk, we argue that social work practice can be enhanced by the inclusion of these principles and practices which are essentially core generic social work practice. However, much of social work with the protection of children is bound by ‘risk’ perceptions which result in investigatory approaches being used as a first action, often to the exclusion of preventive approaches. This article demonstrates that in very different situations from different environments, CD in concert with the principles of the rights of the child can assist good outcomes with children at risk. A model is presented for unifying the worldview of human/children's rights with social work's core concern, the protection of children, using generic social work skills.     

Welfare, labor supply and heterogeneous preferences: evidence for Europe and the US

Following the report of the Stiglitz Commission, measuring and comparing well-being across countries has gained renewed interest. Yet, analyses that go beyond income and incorporate non-market dimensions of welfare most often rely on the assumption of identical preferences to avoid the difficulties related to interpersonal comparisons. In this paper, we suggest an international comparison based on individual welfare rankings that fully retain preference heterogeneity. Focusing on the consumption-leisure trade-off, we estimate discrete choice labor supply models using harmonized microdata for 11 European countries and the US. We retrieve preference heterogeneity within and across countries and analyze several welfare criteria which take into account that differences in income are partly due to differences in tastes. The resulting welfare rankings clearly depend on the normative treatment of preference heterogeneity with alternative metrics. We show that these differences can indeed be explained by estimated preference heterogeneity across countries—rather than demographic composition.
