Symbolic correlation integral

This paper aims to introduce the concept of symbolic correlation integral SC that is extensively used in many scientific fields. The new correlation integral SC avoids the noisy parameter 𝜀 of the classical correlation integral, defined by Grassberger and Procaccia (1983 Grassberger, P., Procaccia, I. (1983). Measuring the strangeness of strange attractors. Physica D: Nonlinear Phenomena 9(1–2):189–208.[Crossref], [Web of Science ®] , [Google Scholar]) and extensively used for constructing correlation-integral-based statistics, as in the BDS test. Once the free parameter 𝜀 disappears, it is possible to construct a nonparametric powerful test for independence that can also be used as a diagnostic tool for model selection. The symbolic correlation integral is also extended to deal with multivariate models, and a test for causality is proposed as an example of the theoretical power of the new concept. With extensive Monte Carlo simulations, the paper shows the good size and power performance of symbolic correlation-integral-based tests.     

Varieties of liberalism: A comparative analysis of family policy and poverty outcomes across the 50 United States

The United States is generally recognised as an exemplar of liberal policy regime types. However, given evidence of state-level divergence in social policy, this article investigates to what extent such variation is present and relevant in state-level family policy. To this end, we pose a primary and secondary research question. Our primary question is whether varieties of liberalism exist across the 50 states in the United States. Our secondary question is whether these varieties of liberalism correspond to variety in social indicators of families' economic well-being. To answer our primary question, we first construct a family policy index that scores the relative generosity and coverage of state-administered social programmes that contribute to the (de)commodification and (de)familialisation of households with children. We then perform a cluster analysis to group states by shared decommodifying and defamilialising features. To answer our secondary question, we investigate how our family-policy clusters are associated with social indicators of families' financial security. Our findings suggest that varieties of liberalism do, indeed, exist within the United States. With the exception of Vermont, which stands out with respect to its comparatively generous family policies, we classify states into two groups: those with ‘soft’ liberal family policy in states featuring relatively generous and accessible policies and ‘hard’ liberal family policy in states achieving little of either. We find that these differences help explain state-level heterogeneity in levels of economic security among households with children, particularly single-mother households.     

‘Making narrative portraits: a methodological approach to analysing qualitative data’

ABSTRACT

This paper proposes the method of ‘narrative portraiture’, which, located within the wider field of narrative studies, offers an analytical tool to narrative data. Two research projects, one on disability and one on identity, are used to illustrate how the method can be applied. While the paper will focus on the methodological benefits and limitations of the approach, throughout the article we also highlight the ethical concern of representation. We suggest that through ‘narrative portraiture’ research findings can be contextualised in broader social narratives without losing sight of the unique personal qualities of the research encounter. Thus, we argue for the importance of bringing the participant and their everyday life experience into focus, highlighting that a portrayal of a sole story can be, not only a medium to understand a research phenomenon, but also a valuable research output in itself.     

(Un)expected exception: validating acquiescent response style factor in the Czech Republic

ABSTRACT

This study explores the acquiescent response style (ARS) among respondents in the Czech Republic. To analyse ARS, confirmatory factor analysis (CFA) was employed and the response style (RS) was modelled as a latent variable. The RS factor in the CFA model must be validated by its relationship to education and age, i.e. proxies of cognitive ability. The two studies presented in this article use large amount of data as all available balanced batteries of items were analysed. In Study 1, the RS factor showed no correlation with age/education in most of the models. Study 2 employed additional measures of cognitive ability and education and confirmed the overall absence of the relationship. Author concludes that the modelled RS factor then cannot be considered the ARS and deduces that the most likely explanation of the identified systematic error variance is the respondents’ carelessness manifested by automatically choosing the extreme agreement, or choosing the first presented answer as a result of memory effect.     

Dirty money? The politics of representation in Cuban revolutionary banknotes

This article examines the visual politics of Cuban postrevolutionary banknotes, focusing on the series minted in 1961. It is argued that the iconography of this series – which stresses the revolutionary merits of Fidel Castro and his movement, and associates the latter with the independence wars – portrays the Castro-led Cuban Revolution as the fulfilment of the nation’s aspiration to sovereignty. The article maintains that the design of the 1961 banknote series articulates tropes that convey a fidelista imaginary, presenting the visual rhetoric of currencies as a mechanism of propaganda and persuasion.     

Work Trajectories of Female and Male Immigrants in Spain

This article aims to examine in depth the work trajectories of individuals over time, in order to provide a wider perspective of the employment history of immigrants compared to native people, by gender and for more than one decade (2005–2017) in Spain. We use microdata (cohort and multivariate analysis) from the Labour Force Survey and carry out a comparison for three groups: the Spanish born in Spain, the Spanish born abroad, and the non-Spanish born abroad. The results confirm that the non-Spanish born-abroad group is characterized by the existence of segmented assimilation. All foreigners suffered a loss in their work trajectories, since their employment rate in 2017 has as yet neither reached the level of the last years of the previous economic expansion nor the level of the previous cohorts at the same age.     

Strains in Sustainability Debates: Traditional Ecological Knowledge and Western Science through the Lens of Extension Agents in a Pastoral Region

Those involved in sustainability debates on developmental pathways concur in the synergistic potential of integrating traditional ecological knowledge (TEK) and Western scientific approaches. Transhumant pastoralism is a livelihood strategy adapted to spatiotemporal environmental variability in many mountainous and arid regions worldwide. This form of livelihood is based on a mobile logic that is increasingly threatened by novel lifestyles promoted from a Western mind-set and by climate change. The aim of this article is to identify and characterize the different perspectives of environmental and social issues in a pastoral region and their association with labor collaboration among extension agents, framed in an institutional action. We tackled the inquiry about viewpoints with Q methodology and related it to regional problems, alternative solutions, and future development pathways for transhumant pastoralism and landscape management in northwest Patagonia. We identified six perspectives and characterized them with their topological position in the social network. Mediating positions registered the highest network centrality of labor collaborations among agents, whereas more dominant perspectives emphasizing TEK or scientific knowledge registered intermediate centrality. There was consensus on the need for sustainable developmental options, but the emphasis on combining knowledge still needs convergent solutions.     

Using the Therapist's Inner Conversation in Teamwork with Novice Therapists

Peter Rober's work (2005a) on the therapist’s inner conversation (TIC) has been a significant contribution to understanding the therapist's 'here and now' experience that focuses on the emergence of different voices responding to what is said in the therapy session. Frediani and Rober (2016) conducted an investigation into the experience and TIC of novice therapists concerning emotions aroused and how they deal with them during family therapy. Their research prompted us to ask how this methodology could work with recent graduates and those in the last year of their undergraduate training. This was addressed in the adolescent psychotherapy team that is part of the Equipo de Trabajo y Asesoría Sistémica (Systemic Counselling and Teamwork) (eQtasis) of the Psychology Department of the University of Chile. An important characteristic has been developing an ethics for clinical practice and generating a collaborative reflexive approach as a central aspect of the clinical training. The paper aims to promote the legitimacy of the experience of novice therapists who despite limited professional experience have many stories that connect with what is said in therapy.
