    On walk entropies in graphs. Response to Dehmer and Mowshowitz
    with Ernesto Estrada and Naomichi Hatano
    Complexity 21 (S1): 15-18. 2016.
    We provide here irrefutable facts that prove the falsehood of the claims published in [1] by Dehmer and Mowshowitz (DM) against our paper published in [2]. We first prove that Dehmer’s definition of node probability [3] is flawed. In addition, we show that it was not Dehmer in [3] who proposed this definition for the first time. We continue by proving how the use of Dehmer’s definition does not reveal all the physico-mathematical richness of the walk entropy of graphs. Finally, we show a few fac…Read more

    Isonymy and the structure of the Provençal-italian ethnic minority
    with G. Biondi, A. Vienna, and C. G. N. Mascie-Taylor
    Journal of Biosocial Science 37 (2): 163-174. 2005.
    Surnames were obtained for the second half of the 20th century from civil and religious marriage registers on fifteen Provençal-Italian and five Italian villages of Cuneo Province, Italy. To insert in the analysis an outward comparison, surnames from two Italian villages of Turin Province, one parish of Turin, one village of Alessandria Province and one village of Asti Province were also collected. Ethnicity does not seem to be the main factor affecting the present genetic structure of the Prove…Read more

    The focus of this work is the analysis of changes in completed family size and possible determinants of that size over time, in an attempt to characterize the evolution of reproductive patterns during the demographic transition. With this purpose in mind, time trends are studied in relation to the mean number of live births per family (as an indirect measure of fertility), using family reconstitution techniques to trace the reproductive history of each married woman. The population surveyed is a…Read more

    Demographic and health patterns in a rural community from the basque area in Spain (1800–1990)
    with Miguel A. Alfonso Sánchez, Victoria Panera Mendieta, and Rosario Calderón
    Journal of Biosocial Science 34 (4): 541-558. 2002.
    In this work, the evolution of demographic and health patterns in a Basque rural population from Spain is analysed, as they relate to progress in demographic and epidemiological transition. For this purpose, parochial record data on 13,298 births and 9215 deaths, registered during the 19th and 20th centuries (180090) resulting from cardiovascular diseases and malignant neoplasms (post-transition causes). This last point is in contrast with observations from the first four decades of the 20th cen…Read more

    Capitalism, COVID‐19 and lockdowns
    with Philipp Bagus and Antonio Sánchez-Bayón
    Business Ethics, the Environment and Responsibility 32 (S1): 41-51. 2023.
    Commentators believe that the COVID-19 pandemic reveals the inconveniences of capitalism and that the end of “neoliberalism” could be near. In this article we show that a capitalist ethics is capable to deal with the challenges of pandemics and comes with important advantages such as the prevention of overreactions. We apply both utilitarian and rights-based ethics to the case of epidemics in general and COVID-19 in particular. First a libertarian natural law ethics is used to assess the governm…Read more

    Unifying Gaussian LWF and AMP Chain Graphs to Model Interference
    Journal of Causal Inference 8 (1): 1-21. 2020.
    An intervention may have an effect on units other than those to which it was administered. This phenomenon is called interference and it usually goes unmodeled. In this paper, we propose to combine Lauritzen-Wermuth-Frydenberg and Andersson-Madigan-Perlman chain graphs to create a new class of causal models that can represent both interference and non-interference relationships for Gaussian distributions. Specifically, we define the new class of models, introduce global and local and pairwise Ma…Read more

    On the bias of adjusting for a non-differentially mismeasured discrete confounder
    with Erin E. Gabriel, Arvid Sjölander, and Sourabh Balgi
    Journal of Causal Inference 9 (1): 229-249. 2021.
    Biological and epidemiological phenomena are often measured with error or imperfectly captured in data. When the true state of this imperfect measure is a confounder of an outcome exposure relationship of interest, it was previously widely believed that adjustment for the mismeasured observed variables provides a less biased estimate of the true average causal effect than not adjusting. However, this is not always the case and depends on both the nature of the measurement and confounding. We des…Read more

    Los caminos compartidos del tacto y el sonido hacia la emoción: Evidencias neurocientíficas actuales
    with Álvaro García López, María José Lucía Mulas, and Belén Ruiz Mezcua
    Arbor 199 (810). 2023.
    La característica más representativa de la música es su capacidad de generar emoción. Pero ¿por qué la música emociona? En este artículo mostramos los conocimientos actuales de la teoría musical y la neurociencia que intentan explicar las relaciones que existen entre la música y las emociones. En primer lugar, se repasan los conocimientos actuales sobre el procesamiento de los sonidos musicales a nivel cerebral y las posibles explicaciones del origen de la emoción musical, así como la contribuci…Read more

    On the Monotonicity of a Nondifferentially Mismeasured Binary Confounder
    Journal of Causal Inference 8 (1): 150-163. 2020.
    Suppose that we are interested in the average causal effect of a binary treatment on an outcome when this relationship is confounded by a binary confounder. Suppose that the confounder is unobserved but a nondifferential proxy of it is observed. We show that, under certain monotonicity assumption that is empirically verifiable, adjusting for the proxy produces a measure of the effect that is between the unadjusted and the true measures.

    Bias attenuation results for dichotomization of a continuous confounder
    with Arvid Sjölander and Erin E. Gabriel
    Journal of Causal Inference 10 (1): 515-526. 2022.
    It is well-known that dichotomization can cause bias and loss of efficiency in estimation. One can easily construct examples where adjusting for a dichotomized confounder causes bias in causal estimation. There are additional examples in the literature where adjusting for a dichotomized confounder can be more biased than not adjusting at all. The message is clear, do not dichotomize. What is unclear is if there are scenarios where adjusting for the dichotomized confounder always leads to lower b…Read more

    Simple yet sharp sensitivity analysis for unmeasured confounding
    Journal of Causal Inference 10 (1): 1-17. 2022.
    We present a method for assessing the sensitivity of the true causal effect to unmeasured confounding. The method requires the analyst to set two intuitive parameters. Otherwise, the method is assumption free. The method returns an interval that contains the true causal effect and whose bounds are arbitrarily sharp, i.e., practically attainable. We show experimentally that our bounds can be tighter than those obtained by the method of Ding and VanderWeele, which, moreover, requires to set one mo…Read more
