Comments on “Detecting Outliers in Gamma Distribution” by M. Jabbari Nooghabi et al. (2010)

This note shows that the results presented by Jabbari Nooghabi et al (2010) do not hold in all expected cases. With this, the technique proposed by Kumar and Lalitha (2012) for detecting upper outliers in Gamma samples is also not valid.     

How could conditional cash transfer programme conditionalities reinforce vulnerability? Non‐compliers and policy implementation gaps in Uruguay's Family Allowances

Influential research shows that conditionalities could incentivize recipients of conditional cash transfer programmes (CCTs) to send their children to school and to regular health check‐ups. However, a growing literature is elucidating the risks of conditional transfers, from both a philosophical and an empirical perspective. This article highlights the varied deficits that have accompanied the implementation process in some Latin American countries, as well as the consequences that these deficits might have on the beneficiaries. In particular, it suggests that, rather than reducing vulnerability by improving access to services, conditionalities could be reinforcing vulnerability among non‐compliers if non‐compliance leads to the immediate suspension of the cash transfer and if this sanction is poorly implemented. While this hypothesis has gained attention and is part of both an academic and a political debate, empirical research around it is scarce. This article is an attempt to start filling this gap by focusing on the implementation process of conditionalities in a CCT programme in Uruguay (Family Allowances) and how this is experienced by a group of recipients who failed to comply with the conditionalities and were sanctioned with the suspension of the benefit. In particular, it identifies the main reasons why these beneficiaries did not comply, how they experience the sanction and how they managed—when they do—to apply for the benefit to be restored. Based on a qualitative design of in‐depth interviews, it provides empirical evidence to unpack causal relationships linking conditionalities to increased vulnerability among non‐compliers. Our findings offer evidence on the role played by the conditionalities in reinforcing vulnerability and the possible causal mechanisms that could be operating between both phenomena. This picture of policy implementation constraints that could lead conditionalities to reinforce vulnerability among recipients could be relevant to policy‐makers having to deal with non‐compliance and managing sanctions in CCTs.     

A Brazilian pandemia/monium: A researcher’s search for a ‘New Normal’

This is the narrative of a Brazilian PhD candidate during the first four months of COVID‐19 in Brazil. Her trajectory and feelings are expressed in evocative autoethnographic format, juxtaposed with the main feminist debates and concerns taking place in Brazil during the pandemic. As scenario, an unprecedented worldwide sanitary crisis and local economic, political and social crises, challenging activists, feminists and the researcher herself in posing new questions to understand the world, her country and herself during/after crises. Her own feminist lenses cannot read ‘New Normal’ comfortably.     

What determines exit from social assistance in Spain?

The aim of this article is two-fold. Firstly, we try to identify the main socioeconomic characteristics that explain the dynamics of social assistance in Spain. Secondly, we carry out a number of tests to assess to what extent individual characteristics accounting for duration differ in the different types of exit from social assistance. Analysis of periods on social assistance shows that belonging to an ethnic minority and employability are the two main determining factors leading to prolonged spells of social assistance. The results also show a striking similarity between the profiles of exits from the programmes due to 'successful reasons' and due to fraud. Exits from the programmes for other reasons occur in a clearly different way.     

Process and evaluation of a group intervention for mothers with parenting difficulties

Twenty-one mothers with severe parenting difficulties, including 12 children on the Child Protection Register, were involved in an intensive parenting intervention. The 4-month group-based package included psychotherapy to allow mothers to come to terms with past and present stressors, and direct and video work with mothers and children using a multi-dimensional model of parenting. Considerable positive change in interaction and child centredness was evident when before and after videotapes of the mothers and children were compared. Negative interaction dropped to one-quarter of the pre-group level and mothers were more effective in exercising appropriate control. Of the 12 children on the Child Protection Register, 10 subsequently had their names removed, with both remaining children returning to the mother's care from compulsory care. This compares favourably with area figures, suggesting that about one-third of children are removed annually from the register. The multi-dimensional model of parenting not only provided a basis for measuring mother's skills but a coherent focus for intervention.     

ON THE EQUIVALENCE OF SOME INDICES OF SIMILARITY: IMPLICATION FOR BINARY PRESENCE/ABSENCE DATA

Cohen’s kappa, a special case of the weighted kappa, is a chance‐corrected index used extensively to quantify inter‐rater agreement in validation and reliability studies. In this paper, it is shown that in inter‐rater agreement for 2 × 2 tables, for two raters having the same number of opposite ratings, the weighted kappa, Cohen’s kappa, Peirce, Yule, Maxwell and Pilliner and Fleiss indices are identical. This implies that the weights in the weighted kappa are less important under such assumptions. Equivalently, it is shown that for two partitions of the same data set, resulting from two clustering algorithms having the same number of clusters with equal cluster sizes, these similarity indices are identical. Hence, an important characterisation is formulated relating equal numbers of clusters with the same cluster sizes to the presence/absence of a trait in a reliability study. Two numerical examples that exemplify the implication of this relationship are presented.     

Social Learning in Transnational Spatial Planning Processes: An Analysis of the ‘V4+2’ Cooperation on Spatial Development

ABSTRACT

Social learning can offer a useful lens to analyse multi-actor cooperation processes and their outcomes. In this paper, a conceptual framework based on learning theories is applied to a recent transnational spatial planning process in Central Europe to analyse how the cooperation agenda was shaped, a joint strategy developed, and to understand the possible policy effects of this process. The findings allow a reflection on the potentials of, and challenges for, multi-actor cooperation on spatial planning in large regions covering several countries.
