Testing the Martingale Property of Exchange Rates: A Replication
2010
In this paper, we test the martingale property of a set of U.S. exchange rates already analyzed in a recent paper by Yilmaz [J. of Buss. and Ec. Stat., 2003]. We claim that the tests used by Yilmaz are not the most convenient to test the martingale hypothesis (or the equivalent martingale difference of the returns); hence, we compute a recently proposed test by Kuan and Lee [Stud. in Nonlin. Dyn. and Econ., 2004] and compare our results to Yilmaz's. Striking differences arise, which can give a clue about the type of data generating process governing the evolution of exchange rates in each sub-period.
Parental stress and resilience in autism spectrum disorder and Down syndrome
2020
The aim of this study was to compare parental stress and resilience in parents of children with autism spectrum disorder (ASD), Down syndrome (DS), and typical development (TD), and analyze the relationship between these two constructs. A total of 97 parents participated (ASD: n = 32, DS: n = 23, and TD: n = 42). The instruments used were the Parental Stress Index and the Resilience Scale. The ASD group obtained higher parental stress related to the child’s characteristics but not related to the parents’ characteristics. The three groups obtained moderate resilience, and high resilience was associated with low parental stress in the ASD and DS groups. The higher parental stress obtained in…
El currículo del grado en derecho, los valores fundamentales del ordenamiento jurídico y la educación jurídica clínica: una reformulación de prospect…
2022
En el presente texto se realiza una revisión crítica de la implementación del plan Bolonia en el estudio del Derecho y de cómo este supuso la mercantilización del currículum mediante la influencia de intereses privados en la determinación de los conocimientos y las habilidades a implementar. Esta tarea, que se realizó en detrimento del valor de la educación y del conocimiento como bienes comunes y estructurales en el desarrollo de la personalidad, implicó la incorporación de teorías como la del Capital Humano en la creación de los nuevos recorridos académicos, marginando asignaturas relativas a derechos humanos, filosofía o teoría del derecho, derecho antidiscriminatorio, deontología jurídi…
Experimental duopolies under price guarantees
2011
In a symmetric differentiated experimental duopoly we test the ability of Price Guarantees (PGs) to raise prices above the competitive levels. Different types of PGs ("aggressive" and "soft" price-beating and price-matching) are implemented either as an exogenously imposed market rule or as a business strategy. Our results show that PGs may lead close to the collusive outcome, depending on whether the interaction between duopolists is repeated and provided that the guarantee is not of the "aggressive" price-beating type.
Social work online: a recognition of experiences and practices in Italy
2018
‘The Internet is the fabric or our lives’ [Castells, M. (2001). The Internet Galaxy: Reflections on the Internet, Business, and Society. Oxford: Oxford University Press, p. 1] – but which are the weaves that nowadays connect Italian social workers into such a fabric? Herein we aim at answering this question through a survey of on-line resources, nodes and practices of e-Social Work in Italy. We shall be discussing ICT impact on the Italian context, and the utilization of ICT by Italian social workers, in order to build up the internal and external factors that determine the current utilization levels of these emerging tools within the professional community. A review of the major on-line so…
The presence of the innovative factor in the agricultural producer in the Valencian Community. Tools to promote innovation in rural-urban dialectics
2021
[ES] Este estudio sociológico se centra en la figura del productor agrario valenciano y su comportamiento frente a la innovación. Adoptar una actitud que favorezca la innovación depende de múltiples factores que influyen en la gestión de la empresa agraria. Este estudio utiliza los datos procedentes de una encuesta a productores agrarios valencianos que profundiza en los factores socioeconómicos que pueden decantar al productor agrario hacia una postura favorable a la innovación. Posteriormente, el estudio se centra en obtener un perfil tipo que represente al productor según sus características y las de su explotación, según su actitud innovadora y la orientación hacia factores influyentes,…
Automated analysis of images for molecular quantification in immunohistochemistry.
2018
The quantification of the expression of different molecules is a key question in both basic and applied sciences. While protein quantification through molecular techniques leads to the loss of spatial information and resolution, immunohistochemistry is usually associated with time-consuming image analysis and human bias. In addition, the scarce automatic software analysis is often proprietary and expensive and relies on a fixed threshold binarization. Here we describe and share a set of macros ready for automated fluorescence analysis of large batches of fixed tissue samples using FIJI/ImageJ. The quantification of the molecules of interest are based on an automatic threshold analysis of im…
How do early family systems predict emotion recognition in middle childhood?
2021
Facial emotion recognition (FER) is a fundamental element in human interaction. It begins to develop soon after birth and is important in achieving developmental tasks of middle childhood, such as developing mutual friendships and acquiring social rules of peer groups. Despite its importance, FER research during middle childhood continues to be rather limited. Moreover, research is ambiguous on how the quality of one's early social-emotional environment shapes FER development, and longitudinal studies spanning from infancy to later development are scarce. In this study, we examine how the cohesive, authoritarian, disengaged and enmeshed family system types, assessed during pregnancy and inf…
Trajectories of reading development: A follow-up from birth to school age of children with and without risk for dyslexia
2006
In order to understand why some children are vulnerable to difficulties in their language development and their acquisition of reading skill, the Jyväskylä Longitudinal Study of Dyslexia followed 200 Finnish children from birth to school age. Half of these children had a family history of reading problems and were considered at risk for dyslexia; the other half were not at risk. A novel analysis, mixture modeling, revealed four subgroups with differential developmental trajectories to early reading. The subgroups who showed either a “dysfluent trajectory” (n = 12; 11 at risk vs. 1 control) or a “declining trajectory” (n = 35; 24 vs. 11) contained more children with familial risk for dyslexi…
Aesthetic factors determining quality and comfort in childhood classroom
2016
This study analyses how school age children experience their educational environment. The objective is to collect the determining factors of aesthetic quality and comfort at school. A pluralistic methodology allows: gather both quantitative and qualitative data using photographic elicitation, and show the responses on an artistic way. Eighty-six children participate on this research; they are from 3 until 5 years old, and belong to rural and urban schools of Alicante. The results determine which places of school are more comfortable, pleasant and enjoyable in Early Childhood Education. Pupils are able to examine in a critically form their everyday educational activities and express their op…
