Disentangling the role of interoceptive sensibility in alexithymia, emotion dysregulation, and depression in healthy individuals

Interoception, a multifaceted concept defined as the perception of internal bodily signals, is crucially involved in mental health in general and in emotion regulation in particular, being interoceptive sensibility (IS) one of the most studied interoceptive processes. The main objective of this study was to explore the relationships between IS and emotion regulation processes, analyzing the role of the eight IS dimensions assessed by the Multidimensional Assessment of Interoceptive Awareness-2 (MAIA-2) in alexithymia, emotion dysregulation, and depression. Additionally, this study also aimed to validate the MAIA-2 in a Spanish sample. To do so, 391 healthy adults, native Peninsular Spanish speakers (61.0% women, Mage = 29.00, SDage = 11.40), completed the MAIA-2 and other self-reported questionnaires to measure alexithymia, emotion dysregulation, and depressive symptoms. Results showed that lower scores on the IS dimensions that involve an accepting attitude toward the bodily signals (e.g., not-worrying) were related to alexithymia and emotion dysregulation, which, in turn, predicted depression. Moreover, the eight-factor structure of the MAIA-2 was confirmed with acceptable fit indices. This study highlights the multidimensional nature of the IS and the relevance of IS dimensions that involve a positive appraisal of the body in regulating emotions

Mapping the digitalisation of European political parties

An increasing number of comparative case studies explore the drivers and impacts of digital technologies on political parties (Bennet et al., 2018. The democratic interface: Technology, political organization, and diverging patterns of electoral representation. Information Communication & Society, 21(11), 1655-1680; Gerbaudo, 2019. The digital party: Political organisation and online democracy. Pluto Press), but a large comparative account on how parties are changing due to digitalisation is still lacking. Based on the new Digitalisation in Parties (DIGIPART) Dataset developed by the authors, this paper addresses this gap by empirically assessing the use of digital platforms and their a ordances in 62 parties in ve European countries (France, Italy, Germany, United Kingdom and Spain). Building on previous research by Fitzpatrick (2021. The ve-pillar model of parties' migration into the digital. In O. Barberà, G. Sandri, P. Correa, & J. Rodríguez-Teruel (Eds.), Digital parties: The challenges of online organisation and participation (pp. 23-42). Springer Nature), the aim is to measure variations in the patterns of digitalisation of party activities, and to preliminary explore the relevance of some systemic and intra-organizational factors in shaping the use of party digital innovations (Lupato & Meloni, 2023. Digital intra-party democracy: An exploratory analysis of Podemos and the Labour Party. Parliamentary A airs, 76(1), 22- 42; Raniolo, Vittori and Tarditi 2021. Political parties and new digital technologies: Between tradition and innovation. In O. Barberà, G. Sandri, P. Correa, & J. Rodríguez-Teruel (Eds.), Digital parties: The challenges of online organisation and participation (pp. 181-204). Springer Nature). The preliminary results show that digital solutions are starting to be adopted as a facilitator of internal participation and that larger and older parties seem to be more digitalised than newer and smaller one

Sobre la introducción de la arquitectura palacial en el Mediterráneo Occidental

El palacio es a la vez un tipo de edificio y una alegoría política. La definitiva importación al Mediterráneo Occidental de este tipo arquitectónico y de su lenguaje simbólico se consumó al tiempo que la República romana se transformaba en un Imperio. Pero antes de estos hechos hubo otras experimentaciones con elementos propios de la arquitectura palacial, tanto en ámbito público como privado, en Italia, Sicilia, en el Maghreb occidental y en la península ibérica. En este artículo se propone una definición razonada del término palacio que sirva para su uso analítico, se discute sobre el rol jugado por las grandes poleis mediterráneas, en especial Cartago, en la difusión de estos edificios y se aboga por considerar a las monarquías norteafricanas, aún no suficientemente atendidas por la investigación, como importantes vectores de transmisión de este tipo de arquitectura en el Mediterráneo occidental

Resonancia natural y capacidad individual de acción ecosocial

Transformar el modo de vida individual es necesario para abordar la crisis ecosocial, y resulta perentorio que las políticas comprometidas con su resolución promocionen una capacidad individual de acción ecosocial. Sin embargo, parece que cierta brecha motivacional está obstaculizando la transformación del modo de vida individual. A fin de dar respuesta a esta brecha, ensayamos una mixtura del enfoque de las capacidades con las teorías de Hartmut Rosa. Argumentamos que la resonancia natural funge de factor personal de conversión necesario, si bien no suficiente, para la capacidad de acción ecosocial; y que una política que promocione la resonancia natural se adecuaría también a los requisitos impuestos al desarrollo humano tanto por el enfoque de las capacidades como por la sostenibilidad. -- Transforming individual lifestyles is necessary to address the eco-social crisis and it is imperative that policies committed to its resolution promote the individual capability for eco-social action. However, it appears that a certain motivational gap hinders individual lifestyle change. To address this gap, we explore a blend of the capabilities approach and Hartmut Rosa's theories. We argue that natural resonance serves as a necessary, though not sufficient, personal conversion factor for the capability of eco-social action and that a policy of promoting natural resonance would also meet the demands placed on human development by both the capabilities approach and sustainability

MiR-138-5p Suppresses Cell Growth and Migration in Melanoma by Targeting Telomerase Reverse Transcriptase

Recent evidence suggests the existence of a miRNA regulatory network involving human telomerase reverse transcriptase gene (hTERT), with miR-138-5p playing a central role in many types of cancers. However, little is known about the regulation of hTERT expression by microRNA(miRNAs) in melanocytic tumors. Here, we investigated the effects of miR-138-5p in hTERT regulation in melanoma cells lines. In vitro studies demonstrated higher miR-138-5p and lower hTERT messenger RNA (mRNA)expression in human epidermal melanocytes, compared with melanoma cell lines (A2058, A375, SK-MEL-28) by quantitative polymerase chain reaction (qPCR) observing a negative correlation between them. A2058 melanoma cells were selected to be transfected with miR-138-5p mimic or inhibitor. Using luciferase assay, hTERT was identified as a direct target of this miRNA. Overexpression of miR-138-5p detected by Western blot revealed a decrease in hTERT protein expression (p = 0.012), and qPCR showed a reduction in telomerase activity (p < 0.001). Moreover, suppressions in cell growth (p = 0.035) and migration abilities (p = 0.015) were observed in A2058-transfected cells using thiazolyl blue tetrazolium bromide and flow cytometry, respectively. This study identifies miR-138-5p as a crucial tumor suppressor miRNA involved in telomerase regulation. Targeting it as a combination therapy with immunotherapy or targeted therapies could be used in advanced melanoma treatment; however, more preclinical studies are necessar

Effect of value co-creation on customer satisfaction: the mediating role of brand equity

Value co-creation (VCC) appears as one of the key trends in marketing and management to reactivate the connection with customers. The main objective of this study is to analyze the chain of direct effects: VCC -> Brand Equity (BE) -> Customer Satisfaction (SAT). Furthermore, this research attempts to assess whether, in this chain of effects, there may be an interaction between both antecedent variables (VCC and BE) that enhances the understanding of satisfaction, and contrast the overall model for two segments: customers who booked the hotel through a traditional offline travel agency versus customers who booked online. The model is tested using PLS technique. Data was collected from 575 customers of four-star hotels in Majorca (Spain). Results reinforce the key importance of branding strategies in hotel management while showing that the channel of distribution partially moderates the relationships. Theoretical contribution and managerial implications are discussed

Bullying at school and students' learning outcomes: International perspective and gender analysis

The present study empirically investigates how school-based bullying affects students' learning outcomes taking into consideration international and gender perspectives. The main objective of the present investigation is to provide a better understanding of the consequences of exposure to bullying in the learning process of adolescents. We estimate a statistical function that empirically establishes the relationship between the students' outcomes in mathematics, reading, and science (output) and a wide set of explaining variables (educational factors), among them being bullied. The present study uses a large sample of 612,004 students between 15 and 16 years old, attending 21,903 schools in 79 countries. The data comes from the 2018 round of the Programme for International Student Assessment (PISA). The results indicate that exposure to bullying is associated with decreases in academic achievement in mathematics, reading, and science. In addition, no relevant differences by gender were observed in reading and science, but other factors being equal bullied males scored less than bullied females in math

El (re)descubrimiento del sujeto y el análisis de las experiencias. Nuevos enfoques transdisciplinares al estudio de la guerra civil y la posguerra

El argumento central que desarrolla el presente artículo es que algunos de los principales avances que se han producido en la historiografía focalizada en el estudio de la guerra civil y la dictadura franquista han venido propiciados por el diálogo interdisciplinar mantenido con las vecinas ciencias sociales. En concreto, el interés recae en lo que parece estar siendo un (re)descubrimiento del sujeto y una atención renovada por las experiencias y la agencia de los individuos dentro de los análisis del periodo de guerra y franquismo. En consecuencia, el artículo propone la hipótesis de que es, precisamente, en este interés por los sujetos donde puede seguir produciéndose un fructífero diálogo entre disciplinas, ilustrándolo con algunos ejemplos destacados de perspectivas y giros recientes que, desde terrenos interdisciplinares y a partir de los sujetos, están proponiendo nuevas formas de comprender la guerra y la dictadura
