Grass Roots Promotion of Community Health and Human Rights for People with Disabilities in Post-communist Central Europe: a profile of the Slovak Republic

Individuals living with a disability or chronic illness in post-communist Central and Eastern Europe face significant challenges to quality of life. The government-supported health care infrastructures in the post-communist countries of Central and Eastern Europe remain highly centralised and institutional, which poses particular obstacles to people with disabilities who wish to live independently in their communities. A partial solution to this difficulty has been the development of innovative grass roots organisations that provide community-based support to individuals with disabilities or chronic illness. These disability organisations provide services and advocacy that allow individuals to receive needed support outside of the biomedical institutions, facilitating independent living in the community. They do so, however, in a political and economic environment of immense change, and one with varying degrees of support for non-governmental organisa tions and a Civil Society. The following article profiles this grass roots development in one particularly interesting post-communist Central European country, the Slovak Republic.     

Testing the Significance of Categorical Predictor Variables in Nonparametric Regression Models

In this paper we propose a test for the significance of categorical predictors in nonparametric regression models. The test is fully data-driven and employs cross-validated smoothing parameter selection while the null distribution of the test is obtained via bootstrapping. The proposed approach allows applied researchers to test hypotheses concerning categorical variables in a fully nonparametric and robust framework, thereby deflecting potential criticism that a particular finding is driven by an arbitrary parametric specification. Simulations reveal that the test performs well, having significantly better power than a conventional frequency-based nonparametric test. The test is applied to determine whether OECD and non-OECD countries follow the same growth rate model or not. Our test suggests that OECD and non-OECD countries follow different growth rate models, while the tests based on a popular parametric specification and the conventional frequency-based nonparametric estimation method fail to detect any significant difference.     

Why the Infinite Decision Puzzle is Puzzling

Pulier (2000, Theory and Decision 49: 291) and Machina (2000, Theory and Decision 49: 293) seek to dissolve the Barrett–Arntzenius infinite decision puzzle (1999, Theory and Decision 46: 101). The proposed dissolutions, however, are based on misunderstandings concerning how the puzzle works and the nature of supertasks more generally. We will describe the puzzle in a simplified form, address the recent misunderstandings, and describe possible morals for decision theory.     

Applying State Space to SPC: Monitoring Multivariate Time Series

Monitoring cross-sectional and serially interdependent processes has become a new issue in statistical process control (SPC). In up-to-date SPC literature, Kalman filtering was reported to monitor univariate autocorrelated processes. This paper applies a Kalman filter or state-space method for SPC to monitoring multivariate time series. We use Aoki's approach to estimate the parameter matrices of a state-space model. Multivariate Hotelling T ² control charts are employed to monitor the residuals of the state-space. Examples of this approach are illustrated.     

Inventing adulthoods: a biographical approach to understanding youth citizenship

Traditionally adulthood and citizenship have been synonymous. Yet adulthood is changing. In this paper we explore how young people's evolving understandings of adulthood may contribute towards an understanding of citizenship within the broader context of increasingly extended and fragmented transitions. The paper draws on a unique qualitative longitudinal data set in which 100 young people, from contrasting social backgrounds in the United Kingdom, have been followed over a five‐year period using repeat biographical interviews. We present first the themes that emerged from a cross‐cut analysis of the first of three rounds of interviews distinguishing between relational and individualised understandings of adulthood. We then present a model we developed to capture the ways that young people sought out opportunities for competence and recognition in different fields of their lives. Finally a case study that follows a young woman through her three interviews illustrates how these themes can appear in an individual trajectory. We offer the model and case study as a way of exploring a more subjective approach to citizenship in which participation is not deferred to some distant future in which economic independence is achieved, but is understood as constantly constructed in the present.     

ALTRUISM, MATCHING, AND NONMARKET INSURANCE

Incomplete market insurance gives rise to nonmarket arrangements for coinsurance. We find that the effort altruistically linked individuals take to avoid an accident increases with the degree of altruism. If the degree of altruism is sufficiently high, an economy with nonmarket insurance yields higher social welfare than an economy without nonmarket insurance. As altruism increases, the equilibrium level of effort approaches the second-best solution without the need for costly monitoring. Coinsurance is above (below) the socially optimal level if individuals place greater weight (less weight) on their own utility than on that of their partners.     

A Social Choice Lemma on Voting Over Lotteries with Applications to a Class of Dynamic Games

We prove a lemma characterizing majority preferences over lotteries on a subset of Euclidean space. Assuming voters have quadratic von Neumann–Morgenstern utility representations, and assuming existence of a majority undominated (or “core”) point, the core voter is decisive: one lottery is majority-preferred to another if and only if this is the preference of the core voter. Several applications of this result to dynamic voting games are discussed.This paper was completed after Jeff Banks’s death.
