Working life and retirement pensions in Spain: The simulated impact of a parametric reform

This article aims to offer an ex ante evaluation of the impact of a parametric reform of the Spanish pension system that would involve increasing the reference period used to calculate benefits, an approach proposed many times by various actors in the socio‐economic field. Such gradual change may be categorized as a non‐structural reform of the pension system. This contrasts with reforms of a structural nature that have been very popular in Latin America and elsewhere, involving the creation of defined contribution individual account schemes. As regards the parametric reform proposed in this article, the main findings indicate that it would have a small but negative impact on pension income for pensioners and would reduce income distribution.     

A general bootstrap algorithm for hypothesis testing

The bootstrap is a intensive computer-based method originally mainly devoted to estimate the standard deviations, confidence intervals and bias of the studied statistic. This technique is useful in a wide variety of statistical procedures, however, its use for hypothesis testing, when the data structure is complex, is not straightforward and each case must be particularly treated. A general bootstrap method for hypothesis testing is studied. The considered method preserves the data structure of each group independently and the null hypothesis is only used in order to compute the bootstrap statistic values (not at the resampling, as usual). The asymptotic distribution is developed and several case studies are discussed.     

Bivariate censored regression relying on a new estimator of the joint distribution function

In this paper we study a class of M  -estimators in a regression model under bivariate random censoring and provide a set of sufficient conditions that ensure asymptotic n^1/2-convergence$n^{1/2}\mathrm{-}\mathrm{convergence}$. The cornerstone of our approach is a new estimator of the joint distribution function of the censored lifetimes. A copula approach is used to modelize the dependence structure between the bivariate censoring times. The resulting estimators present the advantage of being easily computable. A simulation study enlighten the finite sample behavior of this technique.     

On “lab rats”

Experimental subjects usually self-select to the laboratory and this may introduce a bias to the conclusions derived from observing their behavior. We analyze data stored by a subject-pool management program at an experimental laboratory and speculate about the effect of individual decisions on returning. Specifically, we test whether experience and earnings in previous sessions together with demographic variables explain the decision to return to the laboratory. We find that males and (in monetary terms) well-performing subjects are more likely to participate in experiments again.     

‘The whole is always smaller than its parts’ – a digital test of Gabriel Tardes' monads

In this paper we argue that the new availability of digital data sets allows one to revisit Gabriel Tarde's (1843–1904) social theory that entirely dispensed with using notions such as individual or society. Our argument is that when it was impossible, cumbersome or simply slow to assemble and to navigate through the masses of information on particular items, it made sense to treat data about social connections by defining two levels: one for the element, the other for the aggregates. But once we have the experience of following individuals through their connections (which is often the case with profiles) it might be more rewarding to begin navigating datasets without making the distinction between the level of individual component and that of aggregated structure. It becomes possible to give some credibility to Tarde's strange notion of ‘monads’. We claim that it is just this sort of navigational practice that is now made possible by digitally available databases and that such a practice could modify social theory if we could visualize this new type of exploration in a coherent way.     

Sexual Desire Inventory: Two or Three Dimensions?

The Sexual Desire Inventory (SDI), developed by Spector, Carey, and Steinberg in 1996, has been widely used to assess sexual desire in men and women throughout the world. This questionnaire categorizes sexual desire in two dimensions: dyadic sexual desire and solitary sexual desire. Our study addressed the factorial structure of the SDI, an aspect that until now has been largely neglected. We recruited two samples of Spanish men and women involved in stable heterosexual relationships. The first sample consisted of 3,417 subjects (1,600 males and 1,817 females), ages 18 to 84; the second sample consisted of 677 subjects (285 males and 392 females), ages 18 to 50. The results of an exploratory factor analysis (EFA) showed that instead of two dimensions the SDI should have three: (1) partner-focused dyadic sexual desire, (2) general dyadic sexual desire for an attractive person, and (3) solitary sexual desire. A confirmatory factor analysis (CFA) supported the robustness of this new three-factor structure. No gender differences were revealed, except for dyadic sexual desire for an attractive person, for which men reported higher scores. Good validity and reliability values were obtained. Moreover, standard scores for men and women by different age groups were developed.     

Teacher Training with a View Towards Developing Favourable Attitudes Regarding Intercultural Education and Cultural Diversity

An analysis of Spanish multiculturalism, together with the lack of systematic teacher training in the area of intercultural education, a fact which was revealed by a review of the educational programmes and strategies developed in our country, has led us to propose a training course which improves the attitudes of teachers and educators towards intercultural education and the ever‐growing cultural diversity in our country. The study, carried out using a quasi‐experimental methodology and based on the Theory of Reasoned Action, revealed that this type of training programme favours a positive predisposition in teachers towards the development of intercultural programmes in schools, a fundamental element in promoting a further dissemination of this particular focus throughout the whole of the educational system.     

What Do We Do When We Discuss? A Micro‐genetic Analysis of Couples’ Conflict

This article focuses on dialogic discursive dynamics present in couples’ conversations about unresolved conflicts. The phenomenon of conflict is addressed as a semiotically mediated process of co‐construction of the self and the relationship. The purpose of this article is to report on patterns of meaning construction in couples’ conflict, with the identification of strategies that promote or hinder resolution. A qualitative exploratory approach was used to focus on the interactional process at the micro‐processing level. Eight married couples participated in the study. The procedure considered asking the couple to discuss unresolved conflict. Recorded data of couples’ dialogues were transcribed to text and assessed through semiotic analysis using a microgenetic protocol (Molina, Del Río, & Tapia, 2015). The results document the use of strategies for conflict regulation such as psychological distancing, opposition, and generalisation on the border between protecting the bond and regulating tension. The dynamics of non‐resolution manifested in polarisation and rigid patterns with increased tension. The ‘in‐motion’ nature of dialogue about conflict is pushed by the semiotic tension that induces variations in subjective positions manifested in speech and actions.
