Understanding neighbourhoods, communities and environments: new approaches for social work research

This article discusses some new ways in which social work research can explore the interaction between neighbourhoods and child and adult wellbeing. The authors note that social work practices are often criticised for taking an individualistic approach and paying too little attention to the service user's environment. The article uses examples of research projects from Chile, the United States of America and Wales, to discuss the use of spatially oriented research methods for understanding neighbourhood factors. Quantitative, qualitative and mixed methods approaches that are particularly appropriate for investigating social work relevant topics are discussed in turn, including quantitative and qualitative uses for geographical information systems (GIS), hierarchical linear modelling (HLM) for analysing spatially clustered data and qualitative mobile interviews. The article continues with a discussion of the strengths and limitations of using spatially orientated research designs in social work research settings and concludes optimistically with suggestions for future directions in this area.     

Fulfilment of basic needs from a subjective point of view in rural Guatemala

Guardiola J, García‐Muñoz T. Fulfilment of basic needs from a subjective point of view in rural Guatemala Int J Soc Welfare 2011: 20: 393–403 © 2010 The Author(s), International Journal of Social Welfare © 2010 Blackwell Publishing Ltd and the International Journal of Social Welfare. The study of subjective wellbeing in developing countries is a relatively new field of research, but interest is increasing among researchers. A few decades ago, techniques such as the basic needs approach were applied in order to understand development. The basic needs framework has recently been used to define and monitor the Millennium Development Goals. However, it is limited when it comes to defining the content of basic needs and determining to what extent they are being satisfied, which leaves this decision to an external authority other than the individual. In this article, we estimated how certain indicators and assets have influenced the perception of basic needs in a rural area of Guatemala using a data set containing 369 interviews with Mayan households. The results allowed us to identify the characteristics or assets that influence the perception of basic needs, leaving the decision as to the Mayan people themselves as to whether their basic needs are being met.     

The Distribution of Public Social Expenditure in Spain: A General Analysis with Special Reference to Age and Social Class

This paper attempts, first, a general analysis of the distributive incidence of social expenditure (both in cash and in kind) in Spain, within a framework of partial equilibrium. Second, the analysis isolates the redistributive effects caused by age differences from those caused by differences between social groups. Within the area of the latter, the type of redistribution that occurs is examined as well as the point to which the middle classes are privileged recipients of public social spending. In these analyses decomposable indices of generalized entropy are used. The data used for verifying the hypotheses are taken from the European Community Household Panel microdata (1995 wave).     

Privatisation des télécommunications et relations de travail en Amérique latine

This article deals with the privatization of telecommunications in the three largest Latin American countries, Argentina, Brazil and Mexico. Labor unions have strongly affected the way telecommunications have been privatized in Latin America and its timing, but they have not been able to keep their traditional influence from waning. Comparing Argentina and Mexico brings to light opposite models of labor relations based, for the one, on the denationalization of management and loss of guaranteed jobs for wage-earners and, for the other, on the maintenance of control over telecommunications by local entrepreneurs and the preservation of guaranteed employment. The more recent privatization implemented in Brazil has fueled debate about the consequences on collective action in an era of open-market telecommunications. — Special issue: Latin America.     

Four comments for the paper from Liu et al. (2019)

We give comments for the paper from Liu et al. (2019) about the Item Response Theory (IRT) model under consideration, the justification to compute Marginal likelihood, about what we learn with the data analysis performed and finally, about the computational issues in this paper.     

Acceptance Sampling Plans from Truncated Life Tests Based on the Generalized Birnbaum–Saunders Distribution

In this article, we develop acceptance sampling plans when the life test is truncated at a pre-fixed time. The minimum sample size necessary to ensure the specified median life is obtained by assuming that the lifetimes of the test units follow a generalized Birnbaum–Saunders distribution. The operating characteristic values of the sampling plans as well as producer's risk are presented. Two examples are also given to illustrate the procedure developed here, with one of them being based on a real data from software reliability.     

Some properties of the tukey g and h family of distributions

The g and h family of distributions, introduced by J.W. Tukey, is generated by a single transformation of the standard normal which allows for symmetry and heavier tails. Selected percentage points are tabulated, and a closed-form solution for the moments, when they exist, is found. A comparison is made with the Pearson system of distributions. The g and h distributions cover most of the Pearson family to an adequate approximation, when the first four moments exist, and also generate a variety of other types of distributions. Selected distributions graphically illustrate the great variety of possible shapes.
