Resumen
The composition of flavonoids of 12 species of plants of the genus Silene introduced into Western Siberia was studied for the first time. The C-diglycoside of apigenin, shaftoside, was isolated from the aboveground part of S. chalcedonica, the structure of which was identified by HPLC, mass spectrometry, and NMR spectroscopy. In all other studied species, the presence of shaftoside and other C-glycosides of flavones was established on the basis of HPLC data. C-diglycoside of apigenin - vicenin-2 was first identified in S. sendtneri, S. roemeri, S. viridiflora, S. paradoxa, S. nemoralis, S. frivaldszkyana, S. colpophylla, S. linicola, S. caramanica. The most common in the studied Silene species are the apigenin monoglycosides vitexin and isovitexin and a number of their derivatives, luteolin derivatives orientin and others are found a little less frequently. The highest content of flavonoids in the aboveground part of the studied species is characterized by S. nemoralis (6.75%), high – S. chalcedonica, S. paradoxa, S. frivaldszkyana, S. caramanica, S. sendtneri (3.35–5.15%). The major component in the sum of flavonoids is shaftoside, the proportion of which in most species ranges from 50 to 90%. It is shown that the composition of flavonoids changes during vegetative development. The phases of maximum accumulation of flavonoids in the aboveground part of 4 Silene species have been determined. In general, the studied Silene species are promising sources of C-glycosylflavones.

Resumen
AbstractFor a sign to be a sign it must bond an object (quality), a signifier, and the idea to which it gives rise (CP 1.339). The paper focuses on the iconicity of silence as a hypoiconic signifier, exploring the semiotics of silence in light of the notions and studies of iconicity. Fascinating parallelisms hold between iconicity and silence. These raise many challenges to the study of each separately, let alone dealing with them jointly. Some icons and some silences are qualities in the real world, others are semiotic forms (signifiers) standing for or denoting objects. Simple, intuitive qualities of iconicity and of silence are naturally grasped and shared from antiquity to the present by cultures and peoples. The paper employs Peirce’s initial basic trichotomy of iconic classes as well as his later hierarchies for studying the iconic stance of silence as a hypoiconic signifier (Secondness). Analyzing and illustrating the possible complexities between forms (a silent signifier), contents, their relations and their interpretations, group hypoiconic silences into silence as an image, silence as a diagram, and silence as a metaphor.

Resumen
This article seeks to present, in its most general terms, the question of the tragic silence and its function within the analysis concerning the Greek tragedy in The Origin of German Tragic Drama, which was written by Walter Benjamin. For this purpose, we turn to two sources related to Benjamin’s analysis: The Star of Redemption, by Franz Rosenzweig, and The Birth of Tragedy, by Nietzsche. However, in addition to the two other thinkers, Benjamin thinks about the issue of the “tragic silence” from the confrontation between “ambiguity” and “paradox”, between “myth” and “history”, in such a way that silence is a means of resistance: while expressing the guilt of the hero, what you see is his/her “silent suffering”, and, instead of being found guilty, the gods themselves are the ones who must recognize their guilt.

Resumen
Women of every culture face a similar problem: loss of voice. Their lives are permeated with silence. Whether their silence results from a patriarchal society that prohibits women from asserting their identity or from a social expectation of gender roles that confine women to an expressive domain-submissive, nurturing, passive, and domestic-rather than an instrumental role where men are dominant, affective and aggressive-women share the common bond of a debilitating silence. Maria Racine, in her analysis of Janie in Zora Neale Hurston's Their Eyes Were Watching God, reaffirms the pervasiveness of this bond: “For women, silence has crossed every racial and cultural boundary” (283). Indeed, Elaine Mar, a Chinese-American writer, in her memoir, Paper Daughter, elucidates the implications of silence for women, “Like Mother I was learning to disappear. Frequently, I sought refuge with her in the basement room, in the silence of empty spaces. But I was also learning to vanish in full sight of others, retreating into myself when physical flight wasn't possible. My voice withered. Silent desire parched my throat” (48). Silence and loss of voice debilitate and stifle women, as they are forced to sublimate their identity in order to survive in their worlds.

Resumen
Abstract In the historical event of the American Revolution, as well as in certain central texts of the American literary imagination, a tension between the power of a community to define itself through language and the resistance of experiential history to such enclosure is represented through a particular form of narrative silence. This narrative form may first suggest repression and the failures of memory. But the American imagination has used narrative silence as a way of representing events that lie outside of the known and planned, in order to preserve the residual life of experience and so to bear witness to the imagina-tion's dependence on the whole of history. In this essay, I argue that this narrative form reveals a central paradox of the American cultural imagination: This imagination successfully encodes its story of community exactly insofar as it creates a place—in language and in thought—for the safely silent acknowl-edgement of the power of experiential knowledge and untold secrets.

Resumen
Alda Björk Valdimarsdóttir’s book of poetry, We Who Are Blind and Nameless, was published in 2015. The first part of the book, titled „The course of signs“, lays the groundwork for the conceptual basis of the work through five poems. These five poems will be examined through close reading and scholarly materials from various sources, such as cognitive literary studies, philosophy, psychology, social studies and neurological research. There is particular focus on how the poems stimulate the imagination of readers and ruffle their feelings; there is a discussion on (conceptual) metaphors, irony, humor, paradox, geometrical shapes, enumeration, anaphora and, not least, silence which is a common theme in Alda’s poetry and also defines the structure of her poems in various ways. This analysis shows how Alda convinces readers to think about the „course of signs“ in both a narrow and wider context. She not only causes readers to think about the paradoxical interplay of silence and signs – and thus man’s ingrained need to both speak and be silent – but also woman’s position within her family/world history and the encroachment of man upon his own environment. Through clever humour and irony, Alda Björk shows how apathetic people often are when faced with signs; how without thinking they give themselves over to them, even though they have other options; how people contribute for the signs to be isolating instead of connecting us with each other – and how they misuse silence or are not able to make use of it.

Resumen
The number of transracial adoptions in the United States, particularly international adoptions, is increasing annually. Counseling psychology as a profession, however, is a relatively silent voice in the research on and practice of transracial adoption. This article presents an overview of the history and research on transracial adoption to inform counseling psychologists of the set of racial and ethnic challenges and opportunities that transracial adoptive families face in everyday living. Particular attention is given to emergent theory and research on the cultural socialization process within these families.

Resumen
En la literatura medieval existe una larga tradición de relatos de travestismo femenino que va desde la hagiografía hasta las novelas caballerescas. En todas, el motivo del cambio de identidad se presta a una multiplicidad de ambigüedades y paradojas que en el Roman de Silence constituyen rasgos fundamentales desde la sintaxis hasta los núcleos temáticos. Asimismo, el personaje de Merlín, figura híbrida por excelencia y emparentada con los tricksters —a los que también se asemeja Silence—, aparece como el catalizador del desenlace de la narración, lo que nos alerta acerca del alcance de las paradojas y equívocos como elementos estructurantes de una obra cuyos características tricksteriles se examinan igualmente aquí.

Resumen
A simple quantum interaction is analyzed, where the paths of two superposed particles asymmetrically cross, while a detector set to detect an interaction between them remains silent. Despite this negative result, the particles' states leave no doubt that a peculiar interaction has occurred: One particle's momentum is changed while the other's remains unaffected, in apparent violation of momentum conservation. Revisiting the foundations of the standard quantum measurement process offers the resolution. Prior to the macroscopic recording of no interaction, a brief critical interval (CI) prevails, during which the particles and the detector's pointer form a subtle entanglement which immediately dissolves. It is this self-cancellation, henceforth "quantum oblivion (QO)," that lies at the basis of some well-known intriguing quantum effects. Such is interaction-free measurement (IFM)1 and its more paradoxical variants like Hardy's Paradox2 and the quantum liar paradox.3 Even the Aharonov–Bohm (AB) effect4 and weak measurement (WM)5 turn out to belong to this group. We next study interventions within the CI that produce some other peculiar effects. Finally, we discuss some of the conceptual issues involved. Under a greater time-resolution of the CI, some non-local phenomena turn out to be local. Momentum is conserved due to the quantum uncertainties inflicted by the particle–pointer interaction, which sets the experiment's final boundary condition.

Resumen
Mykola Khvylovy: The silence explosion in the Death TheatreThe article deals with the Death Theatre in Mykola Khvylovy’s works. The author of the article claims that Death Theatre is the attribute of intermittency, the transition era between the dying/passing and the one who has not been born yet. It shows its atopic/marginal status employing destroying silence, the traditional death attribute. As the analog of the “explosion chaos”, it implies the destruction of clear forms up „to the point”/ „to the bottom” and their infinite deconstructive formation either according to the law of anagramming, or the law of reduction and ellipsis, interval and three dots as well. The gap and emptiness in the text are subject to the effect of the theatre wings deformation, the irresistible mirror/illusory of man existing in reality. This is accompanied by his balancing between the doomed melancholic and euphoria of the one after touching the secrets of creating the new and the paradox of silent, triumphant assertion in its destruction. Liluli 1923, Mykola Khvylovy’s novella, a unique master of life and text, has become the basis for such judgments. Микола Хвылевый: взрыв молчания в Театре СмертиТеатр Смерти — атрибут междувременья, переходной эпохи, ставшей соприкосновением умирающего/отходившего и еще не родившегося, демонстрирует свой атопичный/маргинальный статус путем разрушения традиционного атрибута смерти — молчания. Аналог „хаоса взрыва”, оно предполагает деструкцию четких форм „до точки”/„до основания” и их бесконечное деконструктивное становление по закону не только анаграммирования, но и редукции и эллипсиса, интервала и многоточия. Зияние и пустота в тексте подчинены эффекту деформации кулис в театре, непреодолимой зеркальности/иллюзорности существования человека в реальности, сопровождающееся его балансированием между обреченностью меланхолика и эйфорией прикоснувшегося к тайнам создания нового и к парадоксу триумфального утверждения молчания в его разрушении. Основания для таких суждений дала новелла „Лилюли” 1923 уникального мастера жизни и текста Миколы Хвылевого.

Resumen
Due to their frontline position to fight the coronavirus disease 2019 (COVID-19), the professional and personal life of nurses was severely disrupted. To understand and describe their lived experiences and perceptions during the pandemic’s first wave in France, we interviewed 49 nurses, including 16 nursing students, and 48 of their family members from June to July 2020. Using a purposeful sampling, the semi-structured interviews were scripted according to Abric’s method with probing questions. The interview analysis led to the identification of six paradoxical perceptions concerning the pandemic’s consequences: the Silence Paradox, the Hero Paradox, the Workforce Paradox, the Learning Paradox, the Symbolic Exchange Paradox, and the Uncertainty Paradox. However, despite different experiences, the nurses perceived their frontline position both as a burden jeopardizing their safety and well-being and as a spotlight of nurses’ tough working conditions. Indeed, because they were in the frontline position, nurses and nursing students were psychologically vulnerable, even more so when they felt alone and inadequately protected. Besides, their families were vulnerable too, as they were also exposed to the consequences of the nurses’ frontline engagement. Thus, to preserve their safety and well-being, institutions should also provide them with better organizational support and inclusive leadership, without neglecting their families.

Resumen
One of the most interesting problems in the nascent discipline of astrobiology is more than half-century old Fermi's paradox: why, considering extraordinary young age of Earth and the Solar System in the Galactic context, don't we perceive much older intelligent communities or signposts of their activity? In spite of a vigorous research activity in recent years, especially bolstered by successes of astrobiology in finding extrasolar planets and extremophiles, this problem (also known as the "Great Silence" or "astrosociological" paradox) remains as open as ever. In a previous paper, we have discussed a particular evolutionary solution suggested by Karl Schroeder based on the currently dominant evolutionary doctrine of adaptationism. Here, we extend that discussion with emphasis on the problems such a solution is bound to face, and conclude that it is ultimately quite unlikely. .

Resumen
As in all cultures, the mirror is a recurring symbol in both Latin-American poetry and narratives. It has various meanings when seen in different literary contexts. The most notable poets of the 20th century, such as Jorge Luis Borges, Octavio Paz, and Carlos Pellicer associate it with mystery, horror, silence, emptiness, catastrophe, and everything which is contradictory, paradoxical, and strange. According to some, the mirror itself reveals the source of poetry and literature, a kind of abyss from which something arises out of nothing. It also allows one to see himself through the eyes of the other. In the book of poetry entitled Los espejos comunicantes, Óscar Hahn, the mirror is a constant entity. Like the aforementioned poets, he reiterates the same obsessions, images, and symbols associated with it. However, here the mirror takes on a new dimension which has not been explored by the others. His poems suggest that what is reflected in the mirror, our wishes, dreams, feelings, and fears, are our true reality. The reality displayed in the mirror is beyond our control. It cannot be understood, organized or classified for our own benefit in the name of science and progress. On the contrary, what should be limited by the confines of the mirror escapes and consumes our reality. For Óscar Hahn our true nature is catastrophe, chaos, passion for destruction, and a love of death. This essence emerges from the mirror and devours everything.

Resumen
We review Fermi's paradox (or the 'Great Silence' problem), not only arguably the oldest and crucial problem for the Search for ExtraTerrestrial Intelligence (SETI), but also a conundrum of profound scientific, philosophical and cultural importance. By a simple analysis of observation selection effects, the correct resolution of Fermi's paradox is certain to tell us something about the future of humanity. Already more than three quarters of century old puzzle and a quarter of century since the last major review paper in the field by G. David Brin has generated many ingenious discussions and hypotheses. We analyze the often tacit methodological assumptions built in various answers to this puzzle and attempt a new classification of the numerous solutions proposed in an already huge literature on the subject. Finally, we consider the ramifications of various classes of hypotheses for the practical SETI projects. Somewhat paradoxically, it seems that the class of (neo)catastrophic hypotheses gives, on the balance, the strongest justification to optimism regarding our current and near-future SETI efforts.

Resumen
At the heart of sociology lies a paradox. Sociology recognizes itself as a preeminently modern discipline yet remains virtually silent on what W.E.B. Du Bois identifies as modernity’s “most magnificent drama”: the transoceanic enslavement of Africans. Through a reconsideration of his classic text Black Reconstruction in America, this article offers an answer to the paradox: a profoundly antisocial condition, racial slavery lies beyond the bounds of the social, beyond sociology’s self-defined limits. Consequently, even when actually dealing with racial slavery, social theories—even radical social theories, such as Du Bois’s Marxism—inexorably misrecognize it. Placing the enslavement of Black people at the center of analysis and drawing on the insights of Saidiya Hartman and other radical theorists in Black studies, an underdiscipline of antisociology is proposed as a collective project to provincialize the social and to more adequately account for the incommensurability of antiblackness.

Resumen
Cet article explore ce que nous entendons par « vide spirituel paradoxal » en salle de naissance québécoise : s’il semble évident que la naissance est une expérience humaine intense qui a été longtemps entourée par une dimension spirituelle, cette dernière demeure largement inexplorée en contexte contemporain. Nous préciserons d’abord notre hypothèse de travail : 1) en définissant son aspect paradoxal émergeant du contexte médical actuel ; 2) en cherchant à mieux saisir le terme spirituel pour qu’il reflète la présente originalité du contexte religieux et spirituel ; et 3) en illustrant le vide par le silence de la littérature à ce propos. Nous toucherons ensuite à l’aspect terrain des recherches entreprises par le groupe interdisciplinaire SPIritualité et Naissance (groupe SPIN) sur la spiritualité des parents lors de la naissance de leur enfant, ayant mené à ce jour à : 1) une rencontre multidisciplinaire d’experts (médecine, théologie, parents) analysée avec deux grilles (Galek et al., 2005 ; Hall, 2001) ; et 2) une première catégorisation des types d’expériences spirituelles pouvant être vécues par les parents lors de la naissance. Nous conclurons par un cahier de charges qui devraient réduire les résistances rencontrées par le milieu médical au sujet du projet SPIN et sur les suites du projet. This article explores what we have called the “paradoxical spiritual void” in the delivery rooms of Quebec. If it seems evident that birth is an intense human experience that has had a spiritual dimension for a very long time, this dimension remains largely unexplored in the contemporary context. First, we set out our working hypothesis: 1) by defining its paradoxical aspect emerging from the actual medical context; 2) by trying to get a better grasp of the term spiritual so as to make it reflect the originality of the actual religious and spiritual context; and 3) by illustrating the void by way of the silence of literature on the topic. Then, we enlarge on the practical aspects of the research conducted by the multidisciplinary group SPIrituality and Birth (in French: SPIN) on the spirituality of parents during the birth of their child, which has so far led to: 1) a multidisciplinary meeting of experts (medical, theological, parental) using two analytical frameworks (Galek et al., 2005; Hall, 2001); and 2) a first categorization of types of spiritual experience that can be lived by parents during birth. We conclude by specifying measures that should reduce the resistance met by the medical world concerning the SPIN project and its future developments.

Resumen
Rather than distinguish a phenomenological moment from an ontological moment in Merleau- Ponty’s work, this article aims to recapture its unity by questioning a metaphor that traverses it: that of the writing, the text or the trace. Ontography is the name of a problem and a paradox that Merleau-Ponty’s philosophy bears and assumes: what good is it to say the Being, if it is already written, if every word breaks the silent contact it demands of us? To write is to prolong and reveal a captive meaning in things.

Resumen
Dans cet article, nous avons étendu la recherche dans le domaine du tabou linguistique et nous avons rendu plus clairs certains aspects liés à ce sujet, aspects identifiés et présentés, partiellement, dans l’une de nos études précédentes. Pour illustrer notre description théorique, nous avons choisi des exemples appartenant au discours politique et social de la langue roumaine de l’époque communiste, de la langue roumaine actuelle, mais aussi au vocabulaire international. Nous avons proposé deux critères théoriques de classification du tabou linguistique. L’un d’eux est de nature fonctionnelle et il reflète la relation entre la cause et l’effet impliqués dans la création du tabou. L’autre est un critère pragmatique et il repose sur le principe que le tabou linguistique pourrait être considéré comme un acte de discours qui exprime la relation entre son succès et son échec. Nous avons également identifié certaines caractéristiques paradoxales du tabou. En conséquence, nous avons remarqué qu’un langage d’interdiction (ne pas dire x) génère souvent, en contrepartie, des mots et des phrases chargés stylistiquement. D’un côté, là où il était censé être un manque, le vocabulaire s’enrichit de nouveaux mots ou de paraphrases. D’un autre côté, au niveau pragmatique, le succès total de l’acte d’interdiction implique le silence. Or, par excellence, le tabou linguistique se manifeste comme une forme lexicale.

Resumen
This essay explores modernism's aesthetic and political implications through examining the works of Humphrey Jennings. The essay takes as a starting point the tension inherent to the democratic aesthetic of Mass Observation between the individual observers and the editors who write up. This tension can be effectively examined in terms of what Jacques Rancière calls ‘film fables’: the Aristotelian ‘fable’ of dramatic action and cinema's ‘fable’ of egalitarian treatment of ‘passive’ images. The essay argues that the paradox between the two ‘fables’ can be observed in Jennings's works, especially in his essays on Thomas Gray, his ‘report’ poems, and The Silent Village (1943), a dystopian propaganda film set in a Welsh village invaded by Nazis Germany. By looking at these works, the essay illustrates how the utopian longing for ‘pure art’ in modernism is related to the impossible idea of ‘democracy’.

Resumen
Introduction. The growing number of military and civilian models of firearms equipped with muzzle devices actualizes the expert diagnostics of the facts of using silent shooting devices during committing crimes by their traces on the fired bullets and fired cases. Theoretical analysis. Science has identified a number of regularities of the effect of silent shooting devices on the mechanism of formation and characteristics of traces on bullets and cartridge cases. Among them are the abrasion and smoothing of traces of the barrel bore on bullets, the formation of traces of the body of homemade silent shooting devices when they are misaligned with the barrel bore, the malfunction of the weapon’s automation, which excludes the possibility of displaying traces of the reflector and the ejection port on the cartridge cases. Empirical analysis. In order to identify new regularities of influence of silent shooting devices on the formation of traces on bullets and cartridge cases, a model scientific experiment was conducted. Experimental shooting was conducted from .366 TKM smoothbore rifles models VPO-209 (Paradox) and AK-366 (Lancaster). The PBS-1 with a rubber obturator of a strong degree of wear was used as a silent shooting device. Cartridges of two types were equipped with lead bullets in a polymer shell, gunpowder “Sunar 7.62” and “Falcon”. Results. It is determined that lead bullets of cartridges undergo characteristic deformation when passing the rubber obturator of the silent shooting device. The body of the bullets stretches and bends, in some cases takes a spindle shape. Cases of partial destruction of bullets have been noted. It is proved that the smoothing of the relief of the traces of the barrel bore, characteristic of the contact interaction of a bullet with a rubber obturator, as well as the additional formation of obturator traces on the bullets do not prevent the identification of firearms. Conclusions. The identified regularities expand the possibilities of forensic ballistic examination in determining the facts of the use of silent shooting devices while committing crimes.

Resumen
Este artigo versará sobre os resultados obtidos por meio da análise do poema “Silence”, parte integrante do livro Vastafala, de Antonio Barreto. Investigamos, nesse texto literário, os recursos utilizados pelo sujeito poético cujo objetivo é promover o diálogo evocando a necessidade intrínseca do ser humano que é expressar-se e comunicar-se. Numa aparente ação paradoxal, ele coloca condições para emergência do diálogo. O enunciador de “Silence” espera estabelecer um contato com seu interlocutor por meio de “conversaremos”, explorando várias possibilidades do léxico. A fundamentação teórica que norteou esta análise e interpretação foram os estudos de Martins (2012) que tratam da Estilística e apontam quais estratos devem ser verificados nesse tipo de estudo: o som, a palavra, a sintaxe, os desdobramentos dessas três camadas e aspectos enunciativos; as referências bibliográficas se expandem para Orlandi (2015), que aborda as questões da significação do silêncio, Garcia (2011) cujo propósito seja a comunicação em prosa atentando para “moderna” sobre a estrutura sintática e a feição estilística da frase e Bechara (2009), cujos estudos focalizam a gramática normativa.

Resumen
The Arctic has often been regarded (its various indigenous groups notwithstanding) as a desolate and silent void to be explored and defined by Euro-westerners, usuallyin terms of a masculine competitive ethos and an ethnocentric rhetoric of WesternEnlightenment and progress. Surprisingly, even many Norwegian arctic expeditionsof our own time tend to embody similar narratives of conquest and athletic prowess.Among contemporary North-American writers, however, this kind of discourse isprofoundly questioned, particularly by focusing on the problematic function oflanguage itself in our constructions of the Arctic. This article focuses on three North-American books in which the issue of the Euro-western linguistic appropriation ofthe Arctic, its natural environment as well as its peoples, is a major concern; they areall reflections on the issues of writing and silence with reference to the far north. Thethree books are: Barry Lopez' Arctic Dreams: Imagination and Desire in a NorthernLandscape (1987), Aritha van Herk's Places Far from Ellesmere (1990), and JohnMoss' Enduring Dreams: An Exploration of Arctic Landscape (1996). Central in allof them is the following issue: how to make the wordless landscape or the alienculture speak from under, as it were, the enormous compilation of centuries of Eurowesterntext. The article discusses four major strategies by which these three booksattempt to counteract and subvert earlier Euro-western ethnocentric and monologicnarratives of the Arctic: by the inclusion of feminine and indigenous voices; by thelegitimation of the sensuous life-world of the Arctic itself; by the self-reflexivesubversion of the authority of the language of their own texts; and by the use of astyle of paradox and contradiction. By way of such techniques, the books above try to create more open, dialogic and pluralistic readings of the Arctic.

Resumen
It is evident that better access to improved water sources will lead to the lessening of infant mortality rate (IMR). However, for India, such inference is ambiguous. There is a strong group of academicians such as Sahu et al. (2015) , Arun et al. (2017) and Tripathy and Mishra (2017) and organizations such as UNICEF that firmly believe that if access to the improved water sources can be improved, then there would be tremendous social welfare and much betterment to the IMR. On the other hand, Banerjee et al. (2020) have refuted such claims and opined that access to improved water sources increases the IMR. The empirical validation of their claim has been flawless, but they are somewhat silent on why such a direct relationship between IMR and improved water source exists. They have made a comment based on assumptions that it might be complacency that develops with access to improved water sources that refrain the people to consider any type of water treatment before passing it to infants for drinking. Such a comment might be valid, but neither is it built upon a sound literature review nor does it stand on strong empirics. At this juncture, the present article tests the claim of Banerjee et al. (2020) based on pure empirics.

Resumen
AbstractThe Great Filter interpretation of Fermi's great silence asserts thatNpqis not a very large number, whereNis the number of potentially life-supporting planets in the observable universe,pis the probability that a randomly chosen such planet develops intelligent life to the level of present-day human civilization, andqis the conditional probability that it then goes on to develop a technological supercivilization visible all over the observable universe. Evidence suggests thatNis huge, which implies thatpqis very small. Hanson (1998) and Bostrom (2008) have argued that the discovery of extraterrestrial life would point towardspnot being small and therefore a very smallq, which can be seen as bad news for humanity's prospects of colonizing the universe. Here we investigate whether a Bayesian analysis supports their argument, and the answer turns out to depend critically on the choice of prior distribution.
