An Assessment of Alternative Strategies for Increasing Access to Legal Services

Since the late 1930s, lawyers have argued that their services are not used to the fullest advantage by a large segment of the population. More recently, other concerned groups such as trade unions and consumer organizations also have become convinced that there is an underutilization of lawyers\u27 services, and that it is important to increase access to such services. As a result, attempts have been made to develop alternatives to the traditional methods of providing legal services that to date have proved inadequate in meeting the legal needs of the public. Legal clinics have proliferated, prepaid legal services plans have been inaugurated on a wide scale, and the organized bar has attempted to revitalize its lawyer referral services. All of this has been done, however, without a complete understanding of why people do or do not use lawyers. This Project examines factors said to affect utilization of legal services by analyzing the results of a national survey conducted between 1973 and 1974 by the Special Committee to Survey Legal Needs of the American Bar Association and the American Bar Foundation (ABA-ABF Survey). This analysis reveals that lawyer use depends principally upon three factors—the number of times a person has experienced a legal problem, whether a person owns real property, and whether a person has personal contacts with a lawyer. These findings are then used to evaluate the potential of several alternative legal delivery systems for increasing lawyer use. The Project concludes that closed-panel prepaid plans and legal clinics have the greatest potential for increasing lawyer use, though both may have only a limited impact

Australasian environmental economics: contributions, conflicts and ‘cop-outs’

Australian and New Zealand environmental economists have played a significant role in the development of concepts and their application across three fields within their subdiscipline: non-market valuation, institutional economics and bioeconomic modelling. These contributions have been spurred on by debates within and outside the discipline. Much of the controversy has centred on the validity of valuations generated through the application of stated preference methods such as contingent valuation. Suggestions to overcome some shortcomings in the work of environmental economists include the commissioning of a sequence of non-market valuation studies to fill existing gaps to improve the potential for benefit transfer.bioeconomic modelling, institutional economics, non-market valuation, Environmental Economics and Policy,

Inconsistency of Pitman-Yor process mixtures for the number of components

In many applications, a finite mixture is a natural model, but it can be difficult to choose an appropriate number of components. To circumvent this choice, investigators are increasingly turning to Dirichlet process mixtures (DPMs), and Pitman-Yor process mixtures (PYMs), more generally. While these models may be well-suited for Bayesian density estimation, many investigators are using them for inferences about the number of components, by considering the posterior on the number of components represented in the observed data. We show that this posterior is not consistent --- that is, on data from a finite mixture, it does not concentrate at the true number of components. This result applies to a large class of nonparametric mixtures, including DPMs and PYMs, over a wide variety of families of component distributions, including essentially all discrete families, as well as continuous exponential families satisfying mild regularity conditions (such as multivariate Gaussians).Comment: This is a general treatment of the problem discussed in our related article, "A simple example of Dirichlet process mixture inconsistency for the number of components", Miller and Harrison (2013) arXiv:1301.270

A diagonally inverted LU implicit multigrid scheme for the 3-D Navier-Stokes equations and a two equation model of turbulence

An LU implicit multigrid algorithm is developed to calculate 3-D compressible viscous flows. This scheme solves the full 3-D Reynolds-Averaged Navier-Stokes equation with a two-equation kappa-epsilon model of turbulence. The flow equations are integrated by an efficient, diagonally inverted, LU implicit multigrid scheme while the kappa-epsilon equations are solved, uncoupled from the flow equations, by a block LU implicit algorithm. The flow equations are solved within the framework of the multigrid method using a four-grid level W-cycle, while the kappa-epsilon equations are iterated only on the finest grid. This treatment of the Reynolds-Averaged Navier-Stokes equations proves to be an efficient method for calculating 3-D compressible viscous flows

Reinventing an Organizing Union: Strategies for Change

[Excerpt] Confronted by declining membership and market share as well as an erosion of bargaining strength and political influence, a sense of crisis now pervades many international unions. Some labor unions continue to adhere to programs and practices they have pursued for several decades. But others, faced with challenges so fundamental that their viability is at stake, have chosen to reexamine their basic policies and performance and to reorient their essential course. This paper evaluates the experience of four such international unions, all of which have recently embarked on strategic planning initiatives. Three of the unions – the Electrical Workers (IBEW), Carpenters (UBC), and Painters (IBPAT) – operate primarily in the private sector, representing workers in the construction industry but serving significant branches in other industrial sectors as well. The fourth is a large public –sector union, the Government Employees (AFGE). The membership rolls range from about 100,000 members to more than 700,000 members
