    Transcranial direct current stimulation over the left posterior temporal lobe modulates semantic control: Evidence from episodic memory distortions

    [EN]Evidence accumulates to show that semantic cognition requires, in addition to semantic representations, control processes that regulate the accessibility and use of semantic knowledge in a task- and time-appropriate fashion. Semantic control has been recently proposed to rely on a distributed network that includes the posterior temporal cortex. Along these lines, recent meta-analyses of neuroimaging data and studies with patients suffering from semantic aphasia have suggested that the left posterior middle temporal gyrus (pMTG) is critically involved whenever situational context must constrain semantic retrieval. In the present experiment, we used transcranial direct current stimulation over the left posterior temporal lobe in an attempt to interfere with semantic control while participants performed a DRM task, a procedure for inducing conceptually-based false recognition that is contingent on both activation and control processes. Paralleling findings with patients suffering from brain damage restricted to the temporoparietal cortex, anodal stimulation (relative to sham stimulation) resulted in increased false recognition but intact true recognition. These findings fit well with the idea that the left pMTG is a key component of a semantic control network, the alteration of which results in memory performance that is affected by the intrusion of contextually-inappropriate semantic information

    Encuentros-desencuentros del teatro de corral y de palacio

    En palacio no sólo se representaban obras de gran aparato y tramoya, sino, de forma muy destacada, las mismas, o semejantes, obras escenificadas en los corrales de comedias. Se estudian los acuerdos y desacuerdos entre el teatro de palacio y el teatro de corral, teniendo en cuenta los excesos económicos del teatro cortesano y las protestas que ello produjo.The plays performed in the palace were not exclusively large spectacular productions but also, and most striking, the same or similar plays as in the public theatres were performed here. In this context, I study the similarities and distinctions between public and court theatre, paying attention to the economic excesses of the court theatre and the protests that they produced

    Lope y sus públicos: estrategias para el éxito

    Get PDF
    El teatro en el siglo XVII, frente a lo que ocurría con otros géneros literarios, tenía una importante rentabilidad económica, especialmente en el caso de Lope de Vega, con el triunfo de su comedia. Ello supone que el éxito, la dependencia de su público, cuanto más extenso mejor, se convirtieron en factores centrales en la creación literaria. Como no estaba claramente asumida la rentabilidad económica de la literatura, van a entrar en oposición conceptos como normas de la poética/gusto; valor de mercado/valor cultural; peso de la norma/peso del éxito…, en definitiva, la función del receptor en la creación literaria. Encontramos así al teatro dependiendo de un público que paga y “mantiene la maquinaria lúdica del espectáculo”, y ello está presente, claro, en la escritura y representación de las obras. Es el teatro de la modernidad, bien estudiado por el profesor Vitse (1984 y 1988), en la línea del análisis del profesor Orozco de la relación gusto/justo, es decir, el peso del receptor frente a una poética exenta. Precisamente, es ese peso del público, de la recepción, lo que me interesa aquí, para analizar cómo está presente en elementos constitutivos de la comedia nueva para encauzar y mantener unas expectativas, lo que en su día llamé “mecanismos de construcción para la recepción”. Lope, el gran responsable de la comercialización del teatro,se ve inmerso en un torbellino, en el ojo de un huracán, en las contradicciones inevitables entre el éxito comercial de su teatro y su orgullo de escritor culto, que sufre los ataques por la venalidad de su teatro. (Díez Borque, en prensa) En otros lugares he estudiado el sentido y alcance de la justificación que hace Lope de su teatro en el Arte nuevo y otras obras,1 tomando en consideración los ataques que sufrió por parte de numerosos escritores y teóricos, sus prejuicios culturalistas, su concepto de vulgo, etc. No voy a volver a esto aquí, y remito a los estudios citados. Lo que me interesa ahora es mostrar cómo todo esto está presente en la “poética” de la comedia nueva. Creo que lo primero es exponer cómo era sentido esto por escritores y teóricos del momento

    Sydowia polyspora dominates fungal communities carried by two Tomicus species in pine plantations threatened by Fusarium circinatum

    Producción CientíficaBark beetles (Coleoptera, Scolytinae) carry a diverse filamentous fungal community sometimes acting as vectors or carriers of phytopathogens. In this study, mycobiota carried by two Tomicus species (Tomicus piniperda and Tomicus destruens) were investigated through (i) morphological and molecular identification of taxa; (ii) taxonomic richness, diversity, evenness, dominance and phoresy indices; (iii) ecological network analysis and (iv) statistical co-occurrence analysis. The studied mycobiota were formed by eleven taxa and showed a moderate fungal diversity with low evenness. The fungus Sydowia polyspora was significantly abundant and dominated the community. All the fungal taxa were randomly associated. Both insect species (T. piniperda and T. destruens) were collected from plantations of Pinus radiata infected by Fusarium circinatum. The ecological factors that could drive community ecology and phoretic links between fungi and bark beetles are discussed.Ministerio de Economía, Industria y Competitividad - Fondo Europeo de Desarrollo Regional (project AGL2015-69370-R)Ministerio de Economía, Industria y Competitividad (project AGL2012-39912)Junta de Castilla y León - Fondo Europeo de Desarrollo Regional (grant ORDEN EDU/1083/2013

    Variable selection for classification and forecasting of the family firm's socioemotional wealth

    Get PDF
    Socioemotional wealth (SEW) refers to those family-centered goals that are likely to have a major influence on the strategic decision-making process and performance of family firms. Many studies have used indirect indicators related to family involvement in ownership and management to measure SEW; meanwhile, others have developed scales to directly measure the level and importance of SEW in family firms. Limitations of both indirect and direct measures of SEW lead empirical research on SEW to be under threat. In the current study, we use random forests to identify the important indicators related to financial and economic decisions, as well as family-related measures, for explaining the family firms' SEW and to design a good prediction model using the smallest set of nonredundant indicators. Our results show that the model that exhibits the minimum out-of-bag sample (OOB) error rate includes variables that refer to the presence of family members in the firm's management positions, long-term nonfinancial debt, personnel expenditures, longterm financial investments, short-term financial debt, average storage period, and accounts receivables. For prediction, the model with a reasonably low estimated classification error includes only three variables, which refer to the presence of family members in the firm's management positions, long-term nonfinancial debt, and accounts receivables.Fundación Cajamurci

    ¿Cómo influye en el éxito de la transferencia de conocimiento la percepción que el receptor tiene del emisor?

    Get PDF
    El trabajo aborda el proceso de transferencia de conocimiento, discutiendo la influencia que ejerce la percepción que el receptor de conocimiento tiene de su emisor. Para ello se analiza un caso específico en el que tiene lugar el citado proceso de transferencia de conocimiento: los acuerdos de cooperación tecnológica entre empresa y universidad. Dichos acuerdos constituyen una de las alternativas, junto a la adquisición y el desarrollo interno, de que dispone la empresa en el momento de afrontar el proceso innovador. El análisis se inicia con una aproximación al concepto de conocimiento y a la justificación de la tecnología como forma de conocimiento, tras lo cual se reflexiona sobre su transferencia. Seguidamente se analizan los acuerdos de cooperación tecnológica, entre los que se encuentran los que se establecen con la universidad. A continuación se exponen las principales ideas en relación con la influencia de la percepción del receptor en el éxito de la transferencia. Finalmente los hallazgos teóricos se someten a contraste empírico de manera exploratoria en una muestra de acuerdos de cooperación tecnológica en el ámbito español.This work addresses knowledge transfer by discussing the influence of the recipient’s perception about the source’s reliability. A specific case of knowledge transfer is analyzed: technological cooperation agreements. These agreements are one of the firm’s alternatives in order to culminate the innovative process. The analysis begins with the introduction to the concept of knowledge and the justification of the technology as a type of knowledge, after which a reflection is done on its transfer. Next, technological cooperation agreements are analyzed, specifically university-industry agreements. After that, we address the main ideas linked to recipient’s perception about the source’s reliability in the success of knowledge transfer. Finally, the theoretical findings are tested empirically in a sample of technological cooperation agreement in Spain from an exploratory view

    The paper makes a literary review of degrowth pedagogy. Degrowth has become one of the fundamental approaches posed to survive in a world of limited resources and to face the profound causes of the current crisis. Learning to live better with less turns out to be not a moral postulate but a vital necessity of our species. The paper analyses the current investigations in the field, as well as the relevant publications in 88 peer review articles, focused on degrowth published between 2006 and 2019, including 41 proposals for action, among which 14 are specialized in the field of education. The conclusions point to the urgent and imperative need to change economic and environmental policies, but also mentalities. Decolonising the collective dominant imaginary trapped in consumerism and individualism; educating in a collective and shared lifestyle of voluntary sobriety; deconstructing the productivist reason and adopting an alternative model of eco social future in the unique world we have. The education and the school, as discussed in the paper, has a fundamental role to play in this endeavor.2019-2
