Judges' cognition and market order

We argue that during the crystallization of common and civil law in the 19th century, the optimal degree of discretion in judicial rulemaking, albeit influenced by the comparative advantages of both legislative and judicial rulemaking, was mainly determined by the anti-market biases of the judiciary. The different degrees of judicial discretion adopted in both legal traditions were thus optimally adapted to different circumstances, mainly rooted in the unique, market-friendly, evolutionary transition enjoyed by English common law as opposed to the revolutionary environment of the civil law. On the Continent, constraining judicial discretion was essential for enforcing freedom of contract and establishing a market economy. The ongoing debasement of pro-market fundamentals in both branches of the Western legal system is explained from this perspective as a consequence of increased perceptions of exogenous risks and changes in the political system, which favored the adoption of sharing solutions and removed the cognitive advantage of parliaments and political leaders.

Genetic variants of the FADS gene cluster and ELOVL gene family, colostrums LC-PUFA levels, breastfeeding, and child cognition

Introduction: Breastfeeding effects on cognition are attributed to long-chain polyunsaturated fatty acids (LC-PUFAs), but controversy persists. Genetic variation in fatty acid desaturase (FADS) and elongase (ELOVL) enzymes has been overlooked when studying the effects of LC-PUFAs supply on cognition. We aimed to: 1) to determine whether maternal genetic variants in the FADS cluster and ELOVL genes contribute to differences in LC-PUFA levels in colostrum; 2) to analyze whether these maternal variants are related to child cognition; and 3) to assess whether children's variants modify breastfeeding effects on cognition. Methods: Data come from two population-based birth cohorts (n = 400 mother-child pairs from INMA-Sabadell; and n = 340 children from INMA-Menorca). LC-PUFAs were measured in 270 colostrum samples from INMA-Sabadell. Tag SNPs were genotyped both in mothers and children (13 in the FADS cluster, 6 in ELOVL2, and 7 in ELOVL5). Child cognition was assessed at 14 mo and 4 y using the Bayley Scales of Infant Development and the McCarthy Scales of Children"s Abilities, respectively. Results: Children of mothers carrying genetic variants associated with lower FADS1 activity (regulating AA and EPA synthesis), higher FADS2 activity (regulating DHA synthesis), and with higher EPA/AA and DHA/AA ratios in colostrum showed a significant advantage in cognition at 14 mo (3.5 to 5.3 points). Not being breastfed conferred an 8- to 9-point disadvantage in cognition among children GG homozygote for rs174468 (low FADS1 activity) but not among those with the A allele. Moreover, not being breastfed resulted in a disadvantage in cognition (5 to 8 points) among children CC homozygote for rs2397142 (low ELOVL5 activity), but not among those carrying the G allele. Conclusion: Genetically determined maternal supplies of LC-PUFAs during pregnancy and lactation appear to be crucial for child cognition. Breastfeeding effects on cognition are modified by child genetic variation in fatty acid desaturase and elongase enzymes.

Behavioural Flexibility: evolutionary past and its role in a changing world

A través de la historia de la vida, gran parte de los organismos han desarrollado estrategias para responder a un mundo en constante cambio. Hoy en día, las actividades humanas producen cambios ambientales a una velocidad sin precedentes, lo cual se traduce en grandes desafíos para la persistencia de biodiversidad. Esta investigación evalúa las respuesta de los animales a los cambios ambientales enfocándose en la flexibilidad del comportamiento como estrategia adaptativa. En una primera aproximación a una escala evolutiva, se otorgan evidencias del vínculo hasta ahora tenue entre la cognición e historias de vida, entregando un claro apoyo a la relación entre longevidad, vida reproductiva y el tamaño del cerebro en mamíferos. La longevidad es el centro de muchas hipótesis respecto a las ventajas de desarrollar un cerebro grande, como por ejemplo en la hipótesis del buffer cognitivo y las respuestas flexibles frente a nuevos ambientes. En un segundo nivel, se abordan factores extrínsecos e intrínsecos que podrían explicar las diferencias individuales en innovación, un componente clave en la flexibilidad del comportamiento. Por medio de una aproximación experimental, se evalúan potenciales escenarios que podrían conducir a consistentes diferencias individuales en uno de los principales factores subyacentes a la innovación (i.e. la motivación), y el potencial control endocrino sobre estos escenarios. Posteriormente, con el objetivo de evaluar la respuesta de los animales frente a los cambios ambientales actuales, se explora la respuesta de los animales frente a una de las actividades humanas mas disruptivas sobre los ecosistemas, la urbanización. Por medio de un analisis filogenetico comparativo a nivel global en aves se abordan los mecanismos implicados en la perdida de biodiversidad observada en ambientes urbanos. Los resultados entregan evidencias sobre la importancia de procesos de dispersión local junto con el papel clave de los rasgos de historia de vida, pero en un sentido diferente al clasicamente pensado. Finalmente por medio de una revisión bibliográfica se entregan evidencias teóricas y empíricas que respaldan el rol clave de la flexibilidad del comportamiento en confrontar los desafíos de una vida urbana. La integración de estos resultados muestra cómo el pasado evolutivo contribuye a hacer frente a los retos ambientales actuales, y pone de relieve posibles consecuencias ante un planeta más cambiante que nunca.

La dinàmica de les práctiques científiques des del punt de vista de l'experiencialisme

La tesi doctoral titulada "La Dinàmica de les Pràctiques Científiques des d'un punt de vista experiencialista" té com a objectiu oferir una alternativa a les tesis de Kuhn defensades a l'"Estructura de les Revolucions Científiques". En aquest sentit, s'utilitzaran diferents experiments i models teòrics actuals en l'àmbit de les ciències cognitives per tal de superar la teoria estructuralista de la cognició, quee Kuhn proposa com la base de la seva filosofia de la ciència. Contràriament a aquesta teoria, l'experiencialisme se situa lluny de les tesis estructuralistes, en la mesura en què assumeix que la cognició humana emergeix des de la dinàmica interactiva dels agents cognitius humans entre ells en un entorn material, en tant que agents corporals. A partir d'aquesta interacció dinàmica, l'ésser humà genera un horitzó de sentit. Ja que la interacció entre els éssers humans en un entorn cultural i material és complex, dinàmic i canviant, la generació de sentit emergent no és com una estructura semàntica, coherent i sistemàtica, sinó que ha de ser considerada com un conjunt asistemàtic de perspectives exploratòries que se succeeixen en el temps, en funció dels diferents contextos i propòsits que un agent corporal porta a terme al llarg de la seva interacció dinàmica i temporal amb l'entorn. Com a resultat de tot això, els èssers humans apliquen diferents criteris interactius que donen lloc a diferents perspectives per categoritzar o estructurar el món material i cultural. Aquest punt de vista és completament diferent del kuhnià, donat que el segon argumenta que cada èsser humà té la seva pròpia Gestalt o estructura semàntica que projecta "a priori" sobre la realitat. Aquesta diferència serà molt important no només des d'un punt de vista teòric, sinó també des d'un punt de vista pràctic. Per exemple, s'argumentarà que en l'àmbit de la didàctica de les ciències empíriques, es poden produir canvis beneficiosos significatius si s'utilitzen tesis extretes del model experiencialista de la cognició humana, i es deixen de banda el cognitivisme i el teoreticisme, que són actualment les bases teòriques de la manera en qué funciona l'educació científica. Finalment, conclourem afirmant que la visió experiencialista de la cognició implica assumir una forta relació entre l'ètica i la ciència, puix que els èssers humans són capaços d'utilitzar diferents criteris interactius per explorar la realitat i, per tant, sempre poden buscar millors estragègies per entendre's els uns amb els altres.

MDMA attenuates THC withdrawal syndrome in mice

3, 4-Methylenedioxymethamphetamine (MDMA) and cannabis are widely abused illicit drugs that are frequently consumed in combination. Interactions between these two drugs have been reported in several pharmacological responses observed in animals, such as body temperature, anxiety, cognition and reward. However, the interaction between MDMA and cannabis in addictive processes such as physical dependence has not been elucidated yet. In this study, the effects of acute and chronic MDMA were evaluated on the behavioral manifestations of Δ9-tetrahydrocannabinol (THC) abstinence in mice. THC withdrawal syndrome was precipitated by injecting the cannabinoid antagonist rimonabant (10 mg/kg, i.p.) in mice chronically treated with THC, and receiving MDMA (2.5, 5 and 10 mg/kg i.p.) or saline just before the withdrawal induction or chronically after the THC administration. Both, chronic and acute MDMA decreased in a dose-dependent manner the severity of THC withdrawal. In vivo microdialysis experiments showed that acute MDMA (5 mg/kg, i.p.) administration increased extracellular serotonin levels in the prefrontal cortex, but not dopamine levels in the nucleus accumbens. Our results also indicate that the attenuation of THC abstinence symptoms was not due to a direct interaction between rimonabant and MDMA nor to the result of the locomotor stimulating effects of MDMA. The modulation of the cannabinoid withdrawal syndrome by acute or chronic MDMA suggests a possible mechanism to explain the associated consumption of these two drugs in humans.

Comunicar la ciudad desde el paisaje: hacia una teoría del landscape branding

La necesidad de descodificar los significados inherentes al paisaje, la interactuación sociedadpaisaje (comunicación intra e interpersonal) y, más recientemente, los usos de paisaje a modo de aparador territorial mediático en el ámbito, por ejemplo, de la comunicación publicitaria, del citymarketing o del place branding (comunicación masiva), sirven para plantear el estudio de lo que, de algún modo, representa la persuasión del paisaje, la cual incluye claros tintes emocionales y simbólicos y, por tanto, también comunicacionales. El paisaje en su condición de imagen y/o rostro del territorio acumula la esencia del mensaje implícito en el espacio, posicionándose, de este modo, como la gran metáfora comunicativa de la ciudad. En este sentido, el trabajo de comunicación específico con el intangible paisajístico, unido a la reciente explosión de las denominadas geografías emocionales, plantea una teoría del mensaje territorial basada en la unión de las variables geografía, paisaje, emoción y comunicación. Históricamente, de los estudios de paisaje se han ocupado los geógrafos, arquitectos, historiadores, sociólogos o ambientólogos, entre muchos otros, sin embargo, el paisaje se ha mantenido poco explorado desde la perspectiva de la comunicación. En este sentido, es notoria la proliferación de análisis que ponen el acento en el papel que desarrolla el territorio como mediador de procesos de comunicación o en el estudio de procesos de retroalimentación entre la sociedad y sus espacios (cognición y/o percepción). El actual mercadeo identitario con los lugares se concreta en la creciente producción de marcas territoriales, las cuales acumulan, en los últimos tiempos, un importante protagonismo.

Ansiedad y depresión en parejas que incian un tratamiento de fecundación in vitro (FIV): rol de las estrategias de afrontamiento

Living with infertility and its emotional impact in couples has been frequently investigated. The objective of the present study was to establish in couples that initiate an IVF treatment:(1) their coping profile, anxiety level (State-anxiety; Trait-anxiety) and depression symptomatology;(2) the explanatory power of coping strategies over anxiety and depression levels, depending on gender. Method: we used a transversal study with 92 couples that begun an IVF treatment in the Assisted Reproduction Unit of the Hospital Clinic. All of them respond to the Spanish adaptation of the CRI-A, the STAI and the BDI-I. Results: the IVF population in comparison to the normal sample use less coping strategies and presents lower levels of anxiety and depression. Women IVF in comparison with man employ further avoidance strategies and present a higher score in depression and state-anxiety. Even when some exceptions exist, anxiety and depression levels are not well explained by coping strategies. Conclusions: It has been shown that the use of coping strategies on the IVF population are lower than in normative sample. Most of the couples present low anxiety (state / trait) and depression levels, and just a low percentage present scores that can require clinical attention. Key words: Infertility / IVF / Coping strategies / State anxiety / Trait anxiety / depression.

Assessment of emotional reactivity produced by exposure to virtual environments in patients with eating disorders

The aim of this study was to assess the usefulness of virtual environments representing situations that are emotionally significant to subjects with eating disorders (ED). These environments may be applied with both evaluative and therapeutic aims and in simulation procedures to carry out a range of experimental studies. This paper is part of a wider research project analyzing the influence of the situation to which subjects are exposed on their performance on body image estimation tasks. Thirty female patients with eating disorders were exposed to six virtual environments: a living-room (neutral situation), a kitchen with highcalorie food, a kitchen with low-calorie food, a restaurant with high-calorie food, a restaurant with low-calorie food, and a swimming-pool. After exposure to each environment the STAI-S (a measurement of state anxiety) and the CDB (a measurement of depression) were administered to all subjects. The results show that virtual reality instruments are particularly useful for simulating everyday situations that may provoke emotional reactions such as anxiety and depression, in patients with ED. Virtual environments in which subjects are obliged to ingest high-calorie food provoke the highest levels of state anxiety and depression.

Implicación de la ansiedad y la depresión en los trastronos de alimentación de jovenes con obesidad

Objectives: the goals of the present study were: 1) to compare the levels of anxiety, depression, and eating disorders in young patients assisted at a children"s hospital for obesity; 2) to determine whether anxiety and depression explain the symptoms of the eating disorders; and 3) to know which of these symptoms better discriminate the young people with different degrees of obesity. Materials and method: Descriptive, cross-sectional study with a sample comprised by 281 youngsters (56% girls) aged 11-17 years. The BMI percentiles were calculated by using the WHO growth tables. Two study groups were created: severe obesity and overweight/light-moderate obesity. The following questionnaires were used: Eating Disorders Inventory-2 (EDI-2), depression questionnaire (DQ), and Status-Trait Anxiety Questionnaire (STAI). Results: The youngsters with obesity showed more psychological problems than youngsters with overweight/ light-moderate obesity, 12% had anxiety, and 11% depression. In both groups, the behaviours related with eating disorders were partially explained by the presence of symptoms of anxiety and depression. Dissatisfaction with the body and high anxiety trait increased the risk for perpetuating the obesity and were the two symptoms that better discriminated the patients with or without severe obesity. Conclusion: Obesity prevention programmes should include body dissatisfaction and the anxiety trait into the assessment and management protocols, and prevent anxiety getting fixed as a personality trait.

Effects of manipulating Task Complexity on self-repairs during L2 oral production

This paper analyses the effects of manipulating the cognitive complexity of L2 oral tasks on language production. It specifically focuses on self-repairs, which are taken as a measure of accuracy since they denote both attention to form and an attempt at being accurate. By means of a repeated measures de- sign, 42 lower-intermediate students were asked to perform three different tasks types (a narrative, and instruction-giving task, and a decision-making task) for which two degrees of cognitive complexity were established. The narrative task was manipulated along +/− Here-and-Now, an instruction-giving task ma- nipulated along +/− elements, and the decision-making task which is manipu- lated along +/− reasoning demands. Repeated measures ANOVAs are used for the calculation of differences between degrees of complexity and among task types. One-way ANOVA are used to detect potential differences between low- proficiency and high-proficiency participants. Results show an overall effect of Task Complexity on self-repairs behavior across task types, with different be- haviors existing among the three task types. No differences are found between the self-repair behavior between low and high proficiency groups. Results are discussed in the light of theories of cognition and L2 performance (Robin- son 2001a, 2001b, 2003, 2005, 2007), L1 and L2 language production models (Levelt 1989, 1993; Kormos 2000, 2006), and attention during L2 performance (Skehan 1998; Robinson, 2002).

Las emociones como variables relacionadas con el cambio de hábitos de salud en familiares y amigos próximos de enfermos de cáncer

Study of the changes in health habits of 105 cancer patients’ relatives and close friends after the diagnosis. The aim is to try to verify whether the knowledge of the disease has got some impact in the modification of their life styles. The emotional alterations influence in this change of behaviour has been analysed futhermore. An interview of own creation and HADS (Anxiety Hospital and Depression Scale of Zigmond and Snaith, 1983) instrument, in a Spanish and a Catalan version, were used with this aim. The results show that 21.1% of the participants presented positive changes in their health habits after the diagnosis of the relative or close friend and 11.5% showed negative changes. In relation to the role of the emotions, averages of anxiety (14,33; d.t.=4,98) and depressive (10,17; d.t.=4,93) symptoms were higher in those subjects who made negative changes than in those who did not make any change (9,32; d.t.=5,37 and 6,33; d.t.=4,64). In addition, the youngest participants, with more depressive symptoms and who visit the subject more often, are those who become more assets modifying health habits. The results suggest that emotional alterations, mainly depressive symptoms, are associated with negative change and, therefore, it would be suitable to lend some type of attention to these alterations in the population studied with the purpose of improving their present and future health

Necessitats dels familiars de pacients amb càncer

El càncer produeix un impacte a la família en totes les seves esferes, la família ha de modificar les seves rutines familiars i adoptar nous rols. En el moment del diagnòstic del càncer, a cada família hi ha una persona que assumeix el rol de cuidador principal. Aquest cuidador és el que s’ocupa del malalt a casa i fa d’enllaç entre la família i l’equip sanitari. En front del càncer, la família i el cuidador tenen un conjunt de dubtes, d’inquietuds, de preocupacions que s’acaben traduint en necessitats. L’equip sanitari i Infermeria especialment ha d’atendre aquestes necessitats i ajudar a satisfer-les. Objectiu: L’objectiu principal d’aquest treball es descriure quines són les necessitats que presenten la família i el cuidador dels pacients oncològics. Metodologia: Es va dur a terme una revisió de la literatura entre setembre del 2013 i maig del 2014. Es va utilitzar la base de dades Pubmed, a més de pàgines web i llibres. Es van obtenir un total de 75 fonts, 56 en angles, 18 en espanyol i 1 en català. Resultats: La bibliografia agrupa les necessitats de les famílies i els cuidadors en 7 grans categories: físiques, psicològiques i emocionals, socials, de informació i formació, econòmiques, de transport i espirituals. Pel que fa a necessitats més especifiques, algunes de les més freqüents són tenir informació sobre el pronòstic del malalt, assegurar-se de que l’equip sanitari està donant la millor atenció possible al malalt. Sembla haver-hi una relació entre el grau de no satisfacció de les necessitats i el grau d’ansietat i depressió en la família i el cuidador. Els autors consultats no coincideixen en afirmar si la majoria del les necessitats es veuen satisfetes o no. Conclusions: La família i el cuidador d’un pacient amb càncer també han de rebre atenció per part dels professionals. En moltes ocasions la família treu importància a les seves necessitats per tal de que l’equip sanitari es centri només en el malalt. Infermeria té un paper fonamental en detectar les necessitats dels familiars i cuidadors i en ajudar a satisfer-les, de manera que la família estigui en les millors condicions possibles per cuidar del malalt. Paraules clau: Càncer, família, cuidador, necessitats familiars, rol d’Infermeria

Comunicar la ciudad desde el paisaje: hacia una teoría del landscape branding

The need to decode landscape meanings, the society- landscape interaction (intra- and inter-personal communication) and, more recently, the uses of landscape as a territorial sight linked to advertising communication, citymarketing or place branding (mass communication) highlights the study of landscape persuasion, which includes clear emotional, symbolic and, therefore, communicative aspects. The landscape, as a territory image or face, gathers the essence of the implicit message in the space, thus working as a great metaphor for city communication. Regarding the foregoing, specific communication research with intangible landscapes —together with the recent emergence of emotional geographies— suggests a new territorial message theory based on the union of geographical, landscape, emotional and communicational variables. Landscape has historically been studied by geographers, architects, historians or sociologists, among others researchers, but it has not been analysed from communicational viewpoints. In this sense, the proliferation of analyses highlighting the role played by the territory as a communication mediator in the interaction process between society and its spaces (cognition and/or perception) is also remarkable. Current sales of territorial identities lead to increases in the production of territory brands, which have gathered a noticeable relevance within the last years.
