Timely Indicators for Inequality and Poverty Using the Italian Labour Force Survey

Income distribution measures obtained from standard household income surveys are usually published with a significant delay, of about 2 years. In this paper we propose a methodology for obtaining timelier indicators using the Italian Labour Force Survey (ILFS), a database which collects detailed information not only on individuals’ labour market status, but also on their households and wages. We develop a framework to estimate household labour income and we use it to construct distributional indicators that are available 1 year and half before the standard measures. After discussing the limitations of our approach, we show that the ILFS-based indicators closely track those calculated on standard household income surveys. The suggested indicators are not meant to substitute standard income measures but can offer up-to-date information, with the aim of better monitoring the distributional impact of changing macroeconomic conditions.

     

Children with disabilities in Swedish child welfare – a differentiating and disabling practice

ABSTRACT

Research shows that children with disabilities are victims of violence and abuse to a higher extent than other children and thus need support from social services. In Sweden, cooperation between two different social services units is required to support children with disabilities in socially vulnerable families. In this study, we have examined the intersection between children and disability in a Swedish social services context from the perspective of childhood studies and disability studies. The reasoning of the two units including the child perspective emerged during focus group interviews based on two vignettes. The results show two different rationalities, which has consequences for the disabled child. In spite of a social policy where the ‘best interests of the child’ are meant to prevail and disabilities are meant to be interpreted as barriers in society, children with disabilities seem to be reduced to individuals who are lacking in ability and competency and who are profoundly victimised by power structures that favour the adult perspective in social services.     

Robust analysis of bibliometric data

This work stems from the idea of describing the scientific productivity of Italian statisticians. There are several problems that must be addressed in achieving this goal: What data should be used? Have the data been cleaned? What techniques can be used? We propose the use of multiple sources and multiple metrics to get a complete information base. We check the correctness of the data using multivariate outlier identification techniques. We appropriately transform the data. We apply robust clustering to verify the existence of homogeneous groups. We suggest the use of forward search to establish a ranking among scholars. The proposed methodology, which, in this case, allowed us to group scholars into four homogeneous groups and sort them according to multidimensional data, can be applied to other similar applications in bibliometrics.     

A Permutation Solution to Test for Treatment Effects in Alternation Design Single-Case Experiments

Research involving a clinical intervention is normally aimed at testing the treatment effects on a dependent variable, which is assumed to be a relevant indicator of health or quality-of-life status. In much clinical research large-n trials are in fact impractical because the availability of individuals within well-defined categories is limited in this application field. This makes it more and more important to concentrate on single-case experiments. The goal with these is to investigate the presence of a difference in the effect of the treatments considered in the study. In this setting, valid inference generally cannot be made using the parametric statistical procedures that are typically used for the analysis of clinical trials and other large-n designs. Hence, nonparametric tools can be a valid alternative to analyze this kind of data. We propose a permutation solution to assess treatment effects in single-case experiments within alternation designs. An extension to the case of more than two treatments is also presented. A simulation study shows that the approach is both reliable under the null hypothesis and powerful under the alternative, and that it improves the performance of a considered competitor. In the end, we present the results of a real case application.     

Extensions of Permutation Solutions to Test for Treatment Effects in Replicated Single-Case Alternation Experiments with Multivariate Response

Single-case experiments are frequently used to do research involving a clinical intervention, since large-n trials are often impractical in clinical research. In order to investigate a possible difference in the effect of the treatments considered in the study, nonparametric instruments are valid tools; in particular, permutation solutions work well when we wish to assess differences in treatment effects. We present an extension of a permutation solution to the multivariate response case and to the case of replicated single-case experiments. A simulation study shows that the approach is both reliable under the null hypothesis and powerful under the alternative. At the end, we present the results of an application to two real experiments.     

Seven years of evaluating income management ‐ what have we learnt? Placing the findings of the New Income Management in the Northern Territory evaluation in context

Income management programs ‐ which restrict how some recipients of government transfers can spend these funds ‐ have operated in Australia since 2007. The nature of the programs implemented varies, especially in regard to the combination of voluntary and compulsory elements, and there are also differences in scope and targeting. A number of evaluations and other studies of these programs have been undertaken. These vary in rigour, methodology, and the set of programs considered. This has led to an apparent diversity of findings, which has been exaggerated by selective use in public debate. The largest and most in depth evaluation has been that of ‘New Income Management’ in the Northern Territory. This found that the program had not achieved its objectives and appears to have created dependence. The relative outcomes of the studies are considered.     

Social Worker Assessed Vulnerable Income Management

Despite the small size of the sub program, Social Worker Assessed Vulnerable Welfare Payment Recipients Income Management is often cited as a preferred approach to this type of initiative, being tightly targeted at a group of people with identified high needs, and demonstrated poor outcomes. Although the program was considered in the two recent major evaluations of income management, specific findings relating to it have tended to be overshadowed by the more general finding of an absence of positive outcomes, and indeed potentially negative effects, from compulsory income management. While the size of the sub program has made evaluation difficult, the two major evaluations of income management have nevertheless made specific findings which suggest that the program has had some positive outcomes for a highly marginal participant group. These findings, along with aspects of the operation of the program, including the role played by social workers, and a proposal to abolish the program, are discussed.     

Snarls,Quacks, and Quarrels: Culture and Structure in Political Process Theory

Political process theories of social movements have relied on a set of oppositions between culture and structure that has limited their capacity to capture the supraindividual, durable, and constraining dimensions of culture. The solution is not to abandon an emphasis on objective political structures in favor of potential insurgents' subjective perceptions of political opportunities, but rather to probe the (objective) resources and constraints generated by the cultural dimensions of political structures. Such a perspective would pay closer attention to the cultural traditions, ideological principles, institutional memories, and political taboos that create and limit political opportunities; and would link the master frames that animate protest to dominant political structures and processes.
