Under an observational, transversal, and descriptive design, the study analyze the degree of adjustment of the perceptions of fear of failure as a mediating variable of the estimated relationship between sporting commitment and the appearance of burnout in young handball players in a competitive context. The sample included a total of 479 youth category handball players selected to compete in the Spanish Regional Championships. The age range was 16 −17 years old. With regard to the years of experience variable, 85.4% (...) stated that they have more than 5 years of experience at the federated handball player level. The Spanish version of Performance Failure Appraisal Inventory, Inventory Athletes Burnout Revised, and Sport Commitment Questionnaire were used to assess fear of failure. The correlation patterns evidence that commitment is negative and significantly associated with emotional exhaustion, depersonalization, and fear of failure and positively associated with reduced sense of personal accomplishment. In the standardized direct effect, negative and significant effects were observed between commitment and fear of failure, fear of failure with emotional exhaustion and depersonalization, and on the contrary, a negative and significant effect was observed between fear of failure and reduced sense of personal accomplishment. The evaluated athletes reflect a positive psychological disposition, show pride in having been selected by their territorial teams and reflect a high desire to show their sporting qualities. Despite the emergence of cognitive-emotional processes associated with fear of failure, this has been observed to protect the sense of self-fulfillment through sport effort, although it also has impacts on further emotional exhaustion and loss of value of sport effort.

Background: In an unprecedented situation of interruption of the sporting dynamics, the world of sport is going through a series of adaptations necessary to continue functioning despite coronavirus disease 2019. More than ever, athletes are facing a different challenge, a source of discomfort and uncertainty, and one that absolutely alters not only sports calendars, but also trajectories, progressions, and approaches to sports life. Therefore, it is necessary to identify the levels of psychological vulnerability that may have been generated in the (...) athletes, because of the coexistence with dysfunctional responses during the COVID-19 experience, and which directly influence the decrease of their mental health.Methods: With a descriptive and transversal design, the study aims to identify the state of the dysfunctional psychological response of a sample of Spanish athletes. The DASS-21, Toronto-20, and Distress Tolerance Scale questionnaires were administered to a sample of high-level Spanish athletes in Olympic programs.Results: The results suggest that the analyzed athletes indicate high levels of dysfunctional response when their tolerance is low. In addition, the variables show less relational strength, when the capacity of tolerance to distress is worse and age is lower. At the same time, the greater the anxiety and uncertainty are, leading to more catastrophic and negative thoughts, the younger the athletes are.Conclusions: It is clear that both age and tolerance to distress are considered adequate protective factors for psychological vulnerability in general and for associated dysfunctional responses in particular. Moreover, the psychological resources offered by more experienced athletes are also a guarantee of protection against negativity and catastrophism. (shrink)

Polo’s new books on psychology are examined, in the light of his entire corpus.

The universally recognized backbone of molecular biology describes the flow of genetic information from deoxyribonucleic acid (DNA) to ribonucleic acid (RNA) to protein or gene product, that is, DNA is transcribed into another nucleic acid (RNA), which is single stranded, next some types of RNA are in turn translated into proteins. Translation of nucleic acids to proteins is literally a translation from the genomic language to the metabolic language. Codons formed of a sequence of three nucleic acids summon a specific (...) amino acid. Translation from codons to proteins, that is, protein synthesis, takes place by specialized machinery comprising mRNA, ribosomes, and free amino acids. Inferring the structure of DNA opened the door for tremendous advances in understanding the role of genes in creating life, directing replication, and ongoing metabolic processes responsible for maintaining life at both the cellular and organism level.

One of the early, non-financial uses of blockchain technologies around which several startups have developed was to help manage, monetize, and make the sharing of genomic data more private. Because deidentified genomic data are excluded from HIPAA and many other regulatory contexts worldwide—and is already a widely traded commodity for science valued in the hundreds of millions over the past decade—genomic blockchains proved a promising entry point for using the benefits of blockchains for dissemination and remuneration of data. Several models (...) have been tried, and most have touted their abilities to make users the “owners” of the genomic data in ways in which current models fail. This paper will explore the various existing and potential models for genomic blockchains, review some shortcomings and unmet needs, and explain why no technical solution alone will fulfill the promise of genomic data ownership without regulation.

Background: The COVID-19 pandemic has produced high stress in nurses, affecting their professional quality of life. Different variables affect psychological stress response and professional quality of life. In this context, the role of professional values represents an interesting object of research. Objectives: To analyze the relationship between professional values, perceived stress, and professional quality of life among nurses during the COVID-19 crisis. Research design, participants, and research context: Descriptive cross-sectional study. Participants were 439 registered nurses from the public health system. (...) Perceived stress, professional quality of life, and professional values were evaluated by using measuring instruments adapted and validated in the geographic context of research. Data were collected online in December 2020 during the second wave of the COVID-19 pandemic in Spain. Ethical considerations: This study was approved by the Ethics Committee on Clinical Research of the Principality of Asturias. Findings: Within professional values, ethics obtained higher scores showing the primacy of ethical values among nurses. Moderate correlations between ethics, mastery, expertise, and compassion satisfaction were found. Frontline nurses informed high perceived stress. The correlations between professional values and compassion satisfaction were higher in non-frontline nurses. A moderate negative correlation between perceived stress and compassion satisfaction was found in both groups, which implies that the higher the stress, the lower the satisfaction in the helping relationship. Conclusion: Professional values positively influence compassion satisfaction during the COVID-19 pandemic. Compassion satisfaction presents a negative correlation with fatigue compassion and burnout in frontline and non-frontline nurses. Given the functionality of values both to guide clinical practice professionally and ethically, and prevent dissatisfaction with one’s professional quality of life by reinforcing compassion satisfaction, it is necessary to reinforce them with an intensive and cross-sectional learning during the university training.

A total of 1918 loci, detected by the hybridization of 938 expressed sequence tag unigenes from 26 Triticeae cDNA libraries, were mapped to wheat homoeologous group 4 chromosomes using a set of deletion, ditelosomic, and nulli-tetrasomic lines. The 1918 EST loci were not distributed uniformly among the three group 4 chromosomes; 41, 28, and 31% mapped to chromosomes 4A, 4B, and 4D, respectively. This pattern is in contrast to the cumulative results of EST mapping in all homoeologous groups, as reported (...) elsewhere, that found the highest proportion of loci mapped to the B genome. Sixty-five percent of these 1918 loci mapped to the long arms of homoeologous group 4 chromosomes, while 35% mapped to the short arms. The distal regions of chromosome arms showed higher numbers of loci than the proximal regions, with the exception of 4DL. This study confirmed the complex structure of chromosome 4A that contains two reciprocal translocations and two inversions, previously identified. An additional inversion in the centromeric region of 4A was revealed. A consensus map for homoeologous group 4 was developed from 119 ESTs unique to group 4. Forty-nine percent of these ESTs were found to be homoologous to sequences on rice chromosome 3, 12% had matches with sequences on other rice chromosomes, and 39% had no matches with rice sequences at all. Limited homology was found between wheat ESTs on homoeologous group 4 and the Arabidopsis genome. Forty-two percent of the homoeologous group 4 ESTs could be classified into functional categories on the basis of blastX searches against all protein databases. (shrink)

The focus of this study was to analyze the content, distribution, and comparative genome relationships of 996 chromosome bin-mapped expressed sequence tags accounting for 2266 restriction fragments on the homoeologous group 3 chromosomes of hexaploid wheat. Of these loci, 634, 884, and 748 were mapped on chromosomes 3A, 3B, and 3D, respectively. The individual chromosome bin maps revealed bins with a high density of mapped ESTs in the distal region and bins of low density in the proximal region of the (...) chromosome arms, with the exception of 3DS and 3DL. These distributions were more localized on the higher-resolution group 3 consensus map with intermediate regions of high-mapped-EST density on both chromosome arms. Gene ontology classification of mapped ESTs was not significantly different for homoeologous group 3 chromosomes compared to the other groups. A combined analysis of the individual bin maps using 537 of the mapped ESTs revealed rearrangements between the group 3 chromosomes. Approximately 232 of the consensus mapped ESTs matched sequences on rice chromosome 1 and revealed large- and small-scale differences in gene order. Of the group 3 mapped EST unigenes ∼21 and 32% matched the Arabidopsis coding regions and proteins, respectively, but no chromosome-level gene order conservation was detected. (shrink)

The objectives of this study were to develop a high-density chromosome bin map of homoeologous group 7 in hexaploid wheat, to identify gene distribution in these chromosomes, and to perform comparative studies of wheat with rice and barley. We mapped 2148 loci from 919 EST clones onto group 7 chromosomes of wheat. In the majority of cases the numbers of loci were significantly lower in the centromeric regions and tended to increase in the distal regions. The level of duplicated loci (...) in this group was 24% with most of these loci being localized toward the distal regions. One hundred nineteen EST probes that hybridized to three fragments and mapped to the three group 7 chromosomes were designated landmark probes and were used to construct a consensus homoeologous group 7 map. An additional 49 probes that mapped to 7AS, 7DS, and the ancestral translocated segment involving 7BS also were designated landmarks. Landmark probe orders and comparative maps of wheat, rice, and barley were produced on the basis of corresponding rice BAC/PAC and genetic markers that mapped on chromosomes 6 and 8 of rice. Identification of landmark ESTs and development of consensus maps may provide a framework of conserved coding regions predating the evolution of wheat genomes. (shrink)

The concept of well-being of rural families is part of a theory under construction in which new theoretical elements are constantly being incorporated. This research aims to determine the influence of farmers’ knowledge on the well‑being of cocoa growing families in the departments of Santander, Huila, Meta and Caquetá, Colombia. Four categories of farmers were identified with different levels of knowledge in the management of cocoa cultivation obtained through a cluster analysis. The well-being of cocoa farmers, understood as the balance (...) in the capital endowment of rural households, was obtained through the application of a semi-structured interview with 49 variables of human, cultural, social, political, natural, built, and financial capitals. The results show that cocoa knowledge is heterogeneous in the study area, with a slight improvement towards harvesting, post-harvest and transformation links. There is a positive relationship between cocoa knowledge and the well-being of cocoa farming families. Thus, producers with greater integral knowledge, with emphasis on post-harvest and bean transformation links, showed greater well-being. The Random Forest analysis identified that human capital (political, social, human, and cultural) made the greatest contribution to well-being. The findings show that cocoa knowledge contributes to the well-being of rural households to the extent that it favors vertical relationships (linkages with local governments) and horizontal relationships of producers (participation of association managers, sharing knowledge with friends, neighbors and partners, and cocoa training).

In a variety of synaesthesia, photisms result from affect-laden stimuli as emotional words, or faces of familiar people. For R, who participated in this study, the sight of a familiar person triggers a mental image of "a human silhouette filled with colour". Subjective descriptions of synaesthetic experiences induced by the visual perception of people's figures and faces show similarities with the reports of those who claim to possess the ability to see the aura. It has been proposed that the purported (...) auric perception may be easily explained by the presence of a specific subtype of cross-modal perception. We analyse the subjective reports of four synaesthetes who experience colours in response to human faces and figures. These reports are compared with descriptions of alleged auric phenomena found in the literature and with claims made by experts in esoteric spheres. The discrepancies found suggest that both phenomena are phenomenologically and behaviourally dissimilar. (shrink)

The complex hexaploid wheat genome offers many challenges for genomics research. Expressed sequence tags facilitate the analysis of gene-coding regions and provide a rich source of molecular markers for mapping and comparison with model organisms. The objectives of this study were to construct a high-density EST chromosome bin map of wheat homoeologous group 2 chromosomes to determine the distribution of ESTs, construct a consensus map of group 2 ESTs, investigate synteny, examine patterns of duplication, and assess the colinearity with rice (...) of ESTs assigned to the group 2 consensus bin map. A total of 2600 loci generated from 1110 ESTs were mapped to group 2 chromosomes by Southern hybridization onto wheat aneuploid chromosome and deletion stocks. A consensus map was constructed of 552 ESTs mapping to more than one group 2 chromosome. Regions of high gene density in distal bins and low gene density in proximal bins were found. Two interstitial gene-rich islands flanked by relatively gene-poor regions on both the short and long arms and having good synteny with rice were discovered. The map locations of two ESTs indicated the possible presence of a small pericentric inversion on chromosome 2B. Wheat chromosome group 2 was shown to share syntenous blocks with rice chromosomes 4 and 7. (shrink)

Biologists and philosophers often use the language of determination in order to describe the nature of developmental phenomena. Accounts in terms of determination have often been reductionist. One common idea is that DNA is supposed to play a special explanatory role in developmental explanations, namely, that DNA is a developmental determinant. In this article we try to make sense of determination claims in developmental biology. Adopting a manipulationist approach, we shall first argue that the notion of developmental determinant is causal. (...) We suggest that two different theses concerning developmental determination can be articulated: determination of occurrence and structural determination. We shall argue that, while the first thesis is problematic, the second, opportunely qualified, is feasible. Finally, we shall argue that an analysis of biological causation in terms of determination cannot account for entangled dynamics. Characterising causal entanglement as a particular kind of interactive causation whereby difference-making causes ascribable to different levels of biological organisation influence a particular ontogenetic outcome, we shall, via two illustrative examples, diagnose some potential limits of a reductionist, molecular and intra-level understanding of biological causation.

Fibromyalgia is a chronic pain syndrome characterized by dysfunctional processing of nociceptive stimulation. Neuroimaging studies have pointed out that pain-related network functioning seems to be altered in these patients. It is thought that this clinical symptomatology may be maintained or even strengthened because of an enhanced expectancy for painful stimuli or its forthcoming appearance. However, neural electrophysiological correlates associated with such attentional mechanisms have been scarcely explored. In the current study, expectancy processes of upcoming laser stimulation (painful and non-painful) and (...) its further processing were explored by event-related potentials (ERPs). Nineteen fibromyalgia patients and twenty healthy control volunteers took part in the experiment. Behavioral measures (reaction times and subjective pain perception) were also collected. We manipulated the pain/no pain expectancy through an S1–S2 paradigm (cue-target). S1 (image: triangle or square) predicted the S2 appearance (laser stimulation: warmth or pinprick sensation). Laser stimuli were delivered using a CO2 laser device. Temporal and spatial principal component analyses were employed to define and quantify the ERP component reliability. Statistical analyses revealed the existence of an abnormal pattern of pain expectancy in patients with fibromyalgia. Specifically, our results showed attenuated amplitudes at posterior lCNV component in anticipation of painful stimulation that was not found in healthy participants. In contrast, although larger P2 amplitudes to painful compared to innocuous events were shown, patients did not show any amplitude change in this laser-evoked response as a function of pain predictive cues (as occurred in the healthy control group). Additionally, analyses of the subjective perception of pain and reaction time indicated that laser stimuli preceded by pain cues were rated as more painful than those signaling non-pain expectancy and were associated with faster responses. Differences between groups were not found. The present findings suggest the presence of dysfunction in pain expectation mechanisms in fibromyalgia that eventually may make it difficult for patients to correctly interpret signs that prevent pain symptoms. Furthermore, the abnormal pattern in pain expectancy displayed by fibromyalgia patients could result in ineffective pain coping strategies. Understanding the neural correlates of pain processing and its modulatory factors is crucial to identify treatments for chronic pain syndromes. (shrink)

IntroductionDuring the Coronavirus pandemic, a set of daily stressors are being experienced, all this affects people’s mental health, leading them to have a set of emotional disturbances. Little is known about how people’s age can influence their emotional well-being in the face of prolonged stress generate by the pandemic.ObjectiveTo clarify the presence of emotional aspects such as emotional expressiveness and the frequency of positive and negative affections in people with different age in times of crisis.MethodsThe final sample included 297 Chileans (...) between 22 and 68 years old, recruited through an online survey with the appropriate written informed consent. The study was carried out when the pandemic was spreading in Chile.ResultsThe findings revealed age differences in emotional expressivity and the type of affections experienced. The expression of emotions was more affected by negative affections, the age and the gender of the people. While the avoidance of this emotional expression, by age and affections both positive and negative. Age was a significant predictor of emotional expressiveness.DiscussionFindings suggests that the associations between both variables, varied according to the age group of the people. Furthermore, this finding proposes that although older people are facing the persistent and serious threat of COVID-19, they show better emotional functioning. Which would help to better understand the interaction of both positive and negative life experiences in times of crisis. (shrink)

Psychosocial work factors are implicated in the development of stress and job satisfaction. This relationship has been scarcely studied in so-called singular activities, as is the case of professional drivers. This cross-sectional study of 601 professional drivers assesses psychosocial risks and job satisfaction using Copenhagen Psychosocial Questionnaire and Overall Job Satisfaction questionnaire models. The values of the psychosocial scales of professional drivers were compared with thresholds values of the Spanish working population. The relationships of the psychosocial scales with the level (...) of job satisfaction were examined using logistic regression models, adjusted for age, gender, length of driving license and years of experience. In general, professional drivers have an unfavorable psychosocial environment compared to the average Spanish workers. The relationship between psychosocial scales and job satisfaction is observed, with the most influential variables being the meaning and development of work, integration in the company, social relations, esteem and level of psychological demands.

In this paper, we introduce a dialogue between (post-)phenomenological and decolonial approaches to propose a sentipensante ethics. Emancipating from hegemonic approaches to ethics that privilege rationality over feeling bodies, we conceptualise an analogical ethics of virtues that emerge in the framework of an analectic-responsive experience. In this experience, we specify the affective, interoceptive, and inter-bodily aspects as elements of a sentipensante ethics from an enactivist perspective. This exercise allows us to highlight the foundation of the ethical experience as a participatory (...) virtue-making oriented towards solidary well-being. Finally, it invites us to search for pedagogical practices that cultivate this virtue-making. En este artículo introducimos un diálogo entre enfoques (post-)fenomenológicos y decoloniales para proponer una ética sentipensante. Nos emancipamos de perspectivas hegemónicas que privilegian la racionalidad sobre los cuerpos que sienten, y conceptualizamos una ética analógica de virtudes que emergen en el marco de una experiencia responsiva analéctica. De esta experiencia, precisamos los aspectos afectivos, interoceptivos, e inter-corporales, como elementos de una ética sentipensante desde una perspectiva enactivista. Este ejercicio nos permite resaltar el fundamento de la experiencia ética como un hacer-virtud participativo orientado hacia el bienestar solidario. Finalmente, nos invita a buscar prácticas pedagógicas que cultiven este hacer-virtud. (shrink)

Although we find many merits to Grossmann's fearful ape hypothesis, unlike Grossmann, we see heightened fearfulness as an ontogenetic adaptation, signaling helplessness and fostering caregiving during infancy, which subsequently became exapted to promote cooperation. We also argue that, rather than being the “breeding ground” for enhanced infant fearfulness, cooperative care is more likely the evolved product of enhanced fearfulness.

The study of cellular senescence and proliferative lifespan is becoming increasingly important because of the promises of autologous cell therapy, the need for model systems for tissue disease and the implication of senescent cell phenotypes in organismal disease states such as sarcopenia, diabetes and various cancers, among others. Here, we explain the concepts of proliferative cellular lifespan and cellular senescence, and we present factors that have been shown to mediate cellular lifespan positively or negatively. We review much recent literature and (...) present potential molecular mechanisms by which lifespan mediation occurs, drawing from the fields of telomere biology, metabolism, NAD+ and sirtuin biology, growth factor signaling and oxygen and antioxidants. We conclude that cellular lifespan and senescence are complex concepts that are governed by multiple independent and interdependent pathways, and that greater understanding of these pathways, their interactions and their convergence upon specific cellular phenotypes may lead to viable therapies for tissue regeneration and treatment of age‐related pathologies, which are caused by or exacerbated by senescent cells in vivo.

El propósito de este trabajo es bosquejar los principios de una antropología del silencio en la obra de Edith Stein con base en las siguientes indagaciones preliminares. En la distinción XXIII de su Ordinatio I, Duns Escoto retoma la siguiente definición de persona dada por Ricardo de San Víctor en su De Trinitate: «La existencia incomunicable de la naturaleza intelectual». El estudio de Duns Escoto a este respecto señalará que una entidad singular (haecceitas) es condición de posibilidad de la persona, (...) pero no la persona misma porque esta es incomunicable ya que no la encontramos dentro del orden óntico. Es decir, la individualidad de la persona presenta una unicidad de orden cualitativo que no puede ser expresada por ciencia alguna. De esta opinión es Mariano Crespo quien, con todo, nos marca el camino para comprender en qué consiste dicha individualidad personal en Ser finito y ser eterno en tanto: «…yo, por medio de mi libre actividad, me decido por esta o aquella posibilidad de actuación, me conformo a mí mismo, me construyo como la persona individual que soy.».

RESUMENEl desarrollo embriológico es un fenómeno que ha inspirado la especulación filosófica desde temprano en la historia del pensamiento. Desde los tiempos de Aristóteles dos modelos conceptuales antitéticos se han utilizado tradicionalmente para comprender la embriogénesis: o el embrión posee ya una forma o estructura, o ésta se forma de nuevo en cada generación. Nuestro objetivo en este artículo es mostrar que el contraste entre la posición preformacionista y epigenética persiste a pesar de los formidables avances teóricos y experimentales de (...) la biología del desarrollo contemporánea. El preformacionismo y la epigénesis han perfeccionado constantemente sus posiciones en el curso de la historia con el fin de responder a los retos conceptuales de la época. Este continuo proceso de transformación ha dado lugar a una convergencia parcial entre las dos posiciones. Sin embargo, vamos a argumentar que, a pesar de los esfuerzos por conciliar ambas posturas, esta antinomia, que se erige como una de las más fundamentales de la biología, no será fácil de superar. ABSTRACTThe process of development of the embryo has inspired philosophical speculation since the advent of Western thought. Since the time of Aristotle two antithetical conceptual models have traditionally been used to understand embryogenesis: either form or structure is preformed in the embryo or it is newly formed with each generation. Our aim in this article is to show that the contrast between the pre-formationist and epigenetic positions persists despite the formidable theoretical and experimental advances of contemporary developmental biology. Pre-formationism and epigenesis have constantly refined their positions in the course of history in order to answer the conceptual challenges of each epoch. This process of continuous transformation has resulted in a partial convergence of the two positions. However, we shall argue that, despite the partial successes of this process of continuous convergence, one of the most fundamental antinomies in biology persists. (shrink)

Las críticas a la velocidad, al cambio continuo o al crecimiento han formado parte de muchos debates sobre la deslegitimación del turismo de los últimos tiempos. De manera más o menos explícita, a muchos de ellos les subyace una dimensión ética cuando sugieren que podría o debería desarrollarse de otra forma. Por lo tanto, es tarea de la ética del turismo reflexionar sobre ellas. No obstante, aunque esta ha ido adquiriendo una gran relevancia en los últimos tiempos, aún se trata (...) de una disciplina relativamente joven. Una de las tareas pendientes es la de superar las concepciones tradicionales y estáticas del turismo, porque, a diferencia de muchas actividades, es extraordinariamente heterogéneo, escurridizo y difícilmente controlable. Para avanzar hacia esa dirección, este número plantea un espacio de reflexión sobre la ética del turismo que toma en consideración una perspectiva analítica concreta: la aceleración social. (shrink)

Code-based cryptography is currently the second most promising post-quantum mathematical tool for quantum-resistant algorithms. Since in 2022 the first post-quantum standard Key Encapsulation Mechanism, Kyber (a latticed-based algorithm), was selected to be established as standard, and after that the National Institute of Standards and Technology post-quantum standardization call focused in code-based cryptosystems. Three of the four candidates that remain in the fourth round are code-based algorithms. In fact, the only non-code-based algorithm (SIKE) is now considered vulnerable. Due to this landscape, (...) it is crucial to update previous results about these algorithms and their functioning. The Fujisaki-Okamoto transformation is a key part of the study of post-quantum algorithms and in this work we focus our analysis on Classic McEliece, BIKE and HQC proposals, and how they apply this transformation to obtain IND-CCA semantic security. Since after security the most important parameter in the evaluation of the algorithms is performance, we have compared the performance of the code-based algorithms of the NIST call considering the same architecture for all of them.

A principios de los años ochenta, Michel Foucault impartió unas lecciones sobre la «παρρησία» en el Collège de France. Las lecciones de Foucault se convirtieron en una importante nueva interpretación de la noción de parresía. Básicamente, Foucault distingue entre una _parresía_ política de naturaleza democrática y una _parresía_ filosófica cuyo origen podría ser trazado hasta Platón. En este artículo concentro mi análisis en la _parresía _política, e intento demostrar que la definición de Foucault de este concepto no se corresponde con (...) el pensamiento democrático de la antigua Atenas. Según Foucault, la parresía es «une parole d’au-dessus», una palabra de arriba. Sin embargo, una interpretación alternativa de las fuentes antiguas puede demostrar que en realidad la _parresía _es una palabra de _abajo_. Al contrario de lo que sostiene Foucault, las obras de Eurípides, Demóstenes, Isócrates y otros autores contribuyen a encontrar una raíz popular en la _parresía_, que debería ser definida como la dignidad de la palabra del pueblo.
