Quantification is particularly seductive in times of global uncertainty. Not surprisingly, numbers, indicators, categorizations, and comparisons are central to governmental and popular response to the COVID-19 pandemic. This essay draws insights from critical data studies, sociology of quantification and decolonial thinking, with occasional excursion into the biomedical domain, to investigate the role and social consequences of counting broadly defined as a way of knowing about the virus. It takes a critical look at two domains of human activity that play a (...) central role in the fight against the virus outbreak, namely medical sciences and technological innovation. It analyzes their efforts to craft solutions for their user base and explores the unwanted social costs of these operations. The essay argues that the over-reliance of biomedical research on “whiteness” for lab testing and the techno-solutionism of the consumer infrastructure devised to curb the social costs of the pandemic are rooted in a distorted idea of a “standard human” based on a partial and exclusive vision of society and its components, which tends to overlook alterity and inequality. It contends that to design our way out of the pandemic, we ought to make space for distinct ways of being and knowing, acknowledging plurality and thinking in terms of social relations, alterity, and interdependence.

Kripke-style models with two accessibility relations, one intuitionistic and the other modal, are given for analogues of the modal systemK based on Heyting's prepositional logic. It is shown that these two relations can combine with each other in various ways. Soundness and completeness are proved for systems with only the necessity operator, or only the possibility operator, or both. Embeddings in modal systems with several modal operators, based on classical propositional logic, are also considered. This paper lays the ground for (...) an investigation of intuitionistic analogues of systems stronger thanK. A brief survey is given of the existing literature on intuitionistic modal logic.

Ob množici del grških in rimskih piscev, ki so bila prevedena v slovenski jezik, je Livijeva Zgodovina doslej ostala nekako ob strani. Razen posameznih odlomkov ni bilo prevedenega nič. Količina ohranjenega besedila, avtorjev slog z dolgimi stavčnimi periodami, izbranim besediščem in različnimi retoričnimi prijemi, vse to pred­stavlja za prevajalca gotovo precejšnjo oviro. Z novo knjigo, ki je pred kratkim izšla pri Slovenski matici in prinaša prvih pet Livijevih knjig v prevodu Primoža Simonitija, se sedaj to spreminja. Knjigo je uredil David (...) Movrin, ki je napisal tudi spremno besedo in pripravil obsežen spremni aparat. Prevod zajema nekje sedmino ohranjenega Livijevega dela, ob predvidenem nadaljevanju s skupino prevajalcev si lahko obetamo izid nadaljnjih zvezkov in v doglednem času tudi prevod vsega, kar se je od Livija ohranilo v rokopisnem izročilu.

Many tasks in statistical and causal inference can be construed as problems of entailment in a suitable formal language. We ask whether those problems are more difficult, from a computational perspective, for causal probabilistic languages than for pure probabilistic (or “associational”) languages. Despite several senses in which causal reasoning is indeed more complex—both expressively and inferentially—we show that causal entailment (or satisfiability) problems can be systematically and robustly reduced to purely probabilistic problems. Thus there is no jump in computational complexity. (...) Along the way we answer several open problems concerning the complexity of well-known probability logics, in particular demonstrating the ${\exists \mathbb {R}}$ -completeness of a polynomial probability calculus, as well as a seemingly much simpler system, the logic of comparative conditional probability.

This article approaches the paradigm shift of datafication from the perspective of civil society. Looking at how individuals and groups engage with datafication, it complements the notion of “data politics” by exploring what we call the “contentious politics of data”. By contentious politics of data we indicate the bottom-up, transformative initiatives interfering with and/or hijacking dominant processes of datafication, contesting existing power relations or re-appropriating data practices and infrastructure for purposes distinct from the intended. Said contentious politics of data is (...) articulated in an array of practices of data activism taking a critical stance towards datafication. In data activism, data as mediators take a central role, both as part of an action repertoire or as objects of struggle in their own right. Leveraging social movement studies and science and technology studies, this theoretical essay argues that data activism can be mapped along two analytical dimensions: “data as stakes” vs. “data as repertoires”, and “individual practice vs. collective action”. Mapping action repertoires and tactics along these axes allows us to chart the potential emergence of a political data subject at the intersection of these two dimensions. This furthers our understanding of people’s engagement with data in relation to other forms of activism and existing work in social movement studies. It also helps us interpreting potential trajectories of contemporary social movements, as they increasingly interface with data, devices and platforms. (shrink)

Metaphors abound in both the arts and in science. Due to the traditional division between these enterprises as one concerned with aesthetic values and the other with epistemic values there has unfortunately been very little work on the relation between metaphors in the arts and sciences. In this paper, we aim to remedy this omission by defending a continuity thesis regarding the function of metaphor across both domains, that is, metaphors fulfill any of the same functions in science as they (...) do in the arts. Importantly, this involves the claim that metaphors in arts as well as science have both epistemic and aesthetic functions. (shrink)

In this paper, I explore ways in which metaphors contribute to hermeneutical resistance, that is, to practices that overcome and/or ameliorate hermeneutical injustice. I distinguish two aspects of hermeneutical injustice and two corresponding kinds of resistance: exoteric and esoteric hermeneutical injustice/resistance. The former injustice consists in unjust harm due to an inability to make one's experience understood to others. The latter consists in such a harm due to an inability to fully understand one's own experiences. In exoteric hermeneutical resistance, metaphors (...) can overcome resistances in others to understand oppressed agents' contributions because of its automatic processing and anti-deniability. In esoteric hermeneutical resistance, metaphors may highlight common structures in various aspects of marginalised agent's experiences, they can provide means of denoting social properties obscured by hermeneutical injustice and they can exhibit hermeneutical injustice by resisting interpretation. I illustrate these practices through works by Emily Dickinson, Ralph Ellison, Frantz Fanon, Paul Celan and Nelly Sachs. Those examples show the power of metaphors in hermeneutical resistance.

Recent discussion of the alleged adverse consequences of space colonization by Phil Torres in this journal is critically assessed. While the concern for suffering risks should be part of any strategic discussion of the cosmic future of humanity, the Hobbesian picture painted by Torres is largely flawed and unpersuasive. Instead, there is a very real risk that the skeptical arguments will be taken too seriously and future human flourishing in space delayed or prevented.

The connectivity patterns of many neural circuits are highly ordered and often impressively complex. The intricate order and complexity of neuronal wiring remain not only a challenge for questions related to circuit functions but also for our understanding of how they develop with such an apparent precision. The chemotropic guidance of the growing axon by target‐derived cues represents a central paradigm for how neurons get connected with the correct target cells. However, many studies reveal a remarkable variety of important target‐independent (...) wiring mechanisms. These mechanisms include axonal sorting, axonal tiling, growth cone polarization, as well as cell‐intrinsic mechanisms underlying growth cone sprouting, and neurite branching. Our review focuses on target independent wiring mechanisms and in particular on recent progress emerging from studies on three different sensory systems: olfactory, visual, and somatosensory. We discuss molecular mechanisms that operate during axon‐axon interactions or constitute axon‐intrinsic functions and outline how they complement the well‐known target‐dependent wiring mechanisms.

The Kiki-Bouba effect comprises a relation between two abstract figures and two non-words: the star-shaped figure is called 'Kiki' and the rounded figure 'Bouba'. The effect is explained by a sound-vision synaesthesia: certain sounds are associated with certain shapes in a non-arbitrary manner.When we asked the participants to decide which of the two figures, the star-shaped or the rounded one, to call yin and which yang, some 85% choose the star-shaped figure as yin. There are previous cases of synaesthesia where (...) personality is attributed to numbers or letters. In our results, the word Kiki is overall happy, clever, small, thin, young, unpleasant, and nervous. The starshaped figure is overall clever, tall, small, slim, nervous, unpleasant, and upper-class. That is, the correspondence above all concerns the qualifying adjectives clever, unpleasant, and nervous, as well as the physical appearance small and thin. This brings us to the fat-thin effect. Cinema, literature, comics, and children's programmes are full of contrasting figures: Don Quixote and Sancho Panza, Laurel and Hardy , Asterix and Obelix, Tintin and Captain Haddock, Bert and Ernie , or the Spanish comic about very naughty twin boys called Zipi and Zape . Our main conclusion is that first names and last names are not entirely arbitrary. There is a correspondence between names and physical characteristics and concepts . The Kiki-Bouba effect is a semantic one. (shrink)

The aim of the paper is to improve availability classifications of components for application in construction systems. Construction production systems belong to project-based systems with serial-parallel structures with or without redundant components, and the availability function has a significant impact on the performance indicators of components and systems. The main indicators of function of the components are the availability, capacity, costs, and project time. A new approach to classification makes it possible to choose the most appropriate methodology for assessing component (...) availability in the bidding phase, and managing company’s machine park. The new classification approach was tested on a practical example. The results obtained confirmed the justification for extending the classical approach to the classification of the availability of components. (shrink)

Isabelle Stengers’ cosmopolitical proposal is an influential attempt by a European philosopher to transform the burdensome legacy of Western thought. Reconsidering her comprehensive engagement with the cosmology of the British mathematician and philosopher Alfred North Whitehead, this article reveals two concepts as foundational to Stengers’ cosmopolitics: civilization and commerce. While not usually associated with a critical political theory, in her development of what we call a commercial political ontology, Stengers explores the modes of inheriting these ostracized notions. By tracing the (...) genealogy of this political ontology back to Pericles’ first explicit defense of persuasion as a requisite for civilization, we argue that Pericles’ famous funeral oration provides the structure for Whitehead’s cosmology, and, ultimately, Stengers’ cosmopolitics. As such, we understand her cosmopolitical proposal as a dress rehearsal of a funeral eulogy for bourgeois society. (shrink)

We historically trace various non-conventional explanations for the origin of the cosmic microwave background and discuss their merit, while analyzing the dynamics of their rejection, as well as the relevant physical and methodological reasons for it. It turns out that there have been many such unorthodox interpretations; not only those developed in the context of theories rejecting the relativistic paradigm entirely but also those coming from the camp of original thinkers firmly entrenched in the relativistic milieu. In fact, the orthodox (...) interpretation has only incrementally won out against the alternatives over the course of the three decades of its multi-stage development. While on the whole, none of the alternatives to the hot Big Bang scenario is persuasive today, we discuss the epistemic ramifications of establishing orthodoxy and eliminating alternatives in science, an issue recently discussed by philosophers and historians of science for other areas of physics. Finally, we single out some plausible and possibly fruitful ideas offered by the alternatives. (shrink)

We investigate intuitionistic propositional modal logics in which a modal operator is equivalent to intuitionistic double negation. Whereas ¬¬ is divisible into two negations, is a single indivisible operator. We shall first consider an axiomatization of the Heyting propositional calculus H, with the connectives →,∧,∨ and ¬, extended with . This system will be called Hdn . Next, we shall consider an axiomatization of the fragment of H without ¬ extended with . This system will be called Hdn + . (...) We shall show that these systems are sound and complete with respect to specific classes of Kripke-style models with two accessibility relations, one intuitionistic and the other modal. This type of models is investigated in [2] and [3], and here we try to apply the techniques of these papers to an intuitionistic modal operator with a natural interpretation. The full results of our investigation will be published in [4] and [1]. (shrink)

:There are manifold intriguing issues located within largely unexplored borderlands of bioethics, future studies, and astrobiology. Human enhancement has for quite some time been among the foci of bioethical debates, but the same cannot be said about its global, transgenerational, and even cosmological consequences. In recent years, discussions of posthuman and, in general terms, postbiological civilization have slowly gained a measure of academic respect, in parallel with the renewed interest in the entire field of future studies and the great strides (...) made in understanding of the origin and evolution of life and intelligence in their widest, cosmic context. These developments promise much deeper synergic answers to questions regarding the long-term future of enhancement: how far can it go? Is human enhancement a further step toward building a true postbiological civilization? Should we actively participate and help shape this process? Is the future of humanity “typical” in the same Copernican sense as our location in space and time is typical in the galaxy, and if so, can we derive important insights about the evolutionary pathways of postbiological evolution from astrobiological and Search for ExtraTerrestrial Intelligence studies? These and similar questions could be understood as parts of a possible unifying research program attempting to connect cultural and moral evolution with what we know and understand about their cosmological and biological counterparts.

Spis z naslovom Knjiga Lucija Cecilija izpovedovalcu Donatu o smrtih preganjalcev (De mortibus persecutorum) je ohranjen v enem samem rokopisu iz 11. stoletja, odkritem leta 1778 v samostanski knjižnici v Moisacu. Ob prvi objavi (1779) ga je Etienne Baluze pripisal krščanskemu piscu in učitelju retorike Laktanciju (ok. 250–ok. 325), najbolj znanemu po prvi celoviti obravnavi krščanske vere, spisu Božji nauk (Divinae institutiones), a kmalu so se pojavili dvomi o njegovem avtorstvu. Tako po formi kot po obravnavani temi, strahotnih koncih cesarjev (...) preganjalcev, ki jih je Bog strogo kaznoval za njihove zločine, spis v antični književnosti nima prave primere. Zato je bil deležen različnih opredelitev kot krščanski pamflet, Konstantinov panegirik, konstantinska propaganda ipd. Forma je izrazito retorična, vsebuje tudi elemente krščanskega in poganskega zgodovinopisja in hagiografije, zgleduje se po judovski in antični tradiciji, v njem so opazne sorodnosti z Drugo knjigo Makabejcev in Konstantinovim govorom Oratio ad sanctorum coetum. Po vrsti razprav in člankov za in proti Laktancijevemu avtorstvu, ko se je zdelo že, da dvomov ni več, je leta 2013 izšla knjiga Jeana Rougeja in Daniela de Deckerja z obnovljeno tezo, da je spis služil konstantinski propagandi in je nastal na pobudo cesarja, podkrepljeno s temeljito študijo drugih Laktancijevih del, in argumenti, oprtimi tudi na izsledke računalniško pripravljenih analiz. Zdi se, da vprašanje ostaja odprto. (shrink)

Dans le cadre de sa théorie de la production des figures géométriques par projection des raisons innées, Proclus est le premier à assimiler la phantasia (imagination) au nous pathetikos (intellect passif) évoqué furtivement par Aristote en De Anima III,5. Tout en maintenant cette assimilation, Ammonius (ré)intègrera la notion d’ epinoia dans le processus d’abstraction, statut de la chose abstraite du monde sensible. L’introduction de cette notion provoquera une certaine confusion chez les commentateurs ultérieurs qui, tout en gardant l’assimilation de Proclus, (...) n’hésiteront pas à faire de la phantasia la faculté intellective permettant d’abstraire les formes de la matière en étroite collaboration avec l’intellect actif, de séparer les accidents d’un substrat et de composer des êtres et formes sans substrat.

We describe a significant practical consequence of taking anthropic biases into account in deriving predictions for rare stochastic catastrophic events. The risks associated with catastrophes such as asteroidal/cometary impacts, supervolcanic episodes, and explosions of supernovae/gamma-ray bursts are based on their observed frequencies. As a result, the frequencies of catastrophes that destroy or are otherwise incompatible with the existence of observers are systematically underestimated. We describe the consequences of the anthropic bias for estimation of catastrophic risks, and suggest some directions for (...) future work. (shrink)

: In this paper I attempt to rethink the relationship between art and life by formulating it based on the rereading of the Benjaminian mimetic faculty by the anthropologist Michael Taussig. Taking this position within history as non-teleological change and based on human activity, to uphold a distinction between original and representation metaphysically becomes impossible. This is important in so far as any notion of primacy becomes obsolete, while at the same time one can work with the historical existence, both (...) material and ideational, of initially abstract concepts such as art. Art then is something that in itself does not have a materially specific reality, but forms reality through artworks, institutions, pecuniary allocations or human motivation. Taking art as a world-forming force that is nonetheless historically produced in turn opens up new, pluralist ways of using this historical given for possible futures. (shrink)

Application of the reliability of repairable systems on solving problems from constructing production systems takes an important place in the process of finding the optimal solution among the suggested system choices. The basic hypothesis when using the reliability of the repairable systems is that every machine is representing a component, a fact that is debatable when talking about technical sciences. However, considering the second assumption of the stationary process, the function of the availability is introduced. It represents the measure between (...) the reliability and the benefit of maintaining the components and the system as a whole one. An additional and the last reason for analyzing constructing machine as a whole one has an economic reason. From the aspect of the total cost and the capacity of the system, the function of the availability is catching more and more impact in the process of determinating the total cost in bill of quantities as the most important part of tender documents. Until former works, techno-economic optimisation usually ran over when choosing the system of the construction machines. In the work, there are shown the methodologies for gathering and analyzing the indicators of availabilities per unit of a company's machine park. The time of demission and reparation have been investigated among 34 components in the period of 6 years. Based on the obtained result for different conditions of machine exploitation and facilities, it is suggested the methodology of the future behaviour of the corresponding within the model optimization availability of constructing production system with the aim of eliminating extra criterion. The suggested model takes in consideration the total cost of the components when they are functional, and when they are not. This kind of approach enables the one who take choices decision of the height of profits, in the lenght of work in function of the projection of cash flow and managing with real indicators of functioning the system at the project level. Given the fact that the maintanance policy of machines is based on availability, and not on reliability of components, with the aim of maximizing the availability of different budget scenarios, a logical approach to the selection of the objective function in the terms of management of construction production systems is to minimize costs for a given availability of system constructing machinery is based on the use of historical data base with the values of the operational availability of components, conditions in which they function, in the process of forecasting the project availability for projects that follow. Ranking variant solutions is the result of the adopted function of the aim as a consequence due to enlargement methods of availability for serial parallel systems with the associated restrictions. For optimal system availability is taken a value that belongs to minimal total cost. However, it is predicted that after the end of the financial year, the real and projected indicators of system functions get compared to each other. Informational support to the proposed model is informational company system, which was built in the PHP programming language on the Linux software platform, and with data based in My SQL. The suggested model is tested on the system for the production and embedding bitumen bound materials on the specific project. Obtained results confirm the assumptions used in work. (shrink)

Clearance phase at signalized crosswalks is an important parameter of pedestrians’ safety because it helps them to complete the crossing before the green signal for vehicles. However, there is the issue of pedestrian decision as to whether to cross if they arrive at the crosswalk during the clearance phase, which represents a violation in many countries. Due to the proof that pedestrian violations multiply the risk of traffic accidents, in this study, the tendency of pedestrians to commit violations during the (...) clearance time has been researched. With the aim of proposing the design of the pedestrian traffic lights, which could decrease the frequency of pedestrian violations, the comparison of pedestrians behaviour at crosswalks with and without a countdown timer during the clearance time was made, based on the data collected in the video recording. Chi square independency test showed that there is a statistically significant difference in the behaviour of pedestrians during the clearance time, depending on the existence of the timer, as well as the fact that pedestrians behave in a safer manner if there is no clearance time shown on the timer. The total delay rate on the roadway during the red signal, which was the consequence of starting the crossing during the clearance time or subsequent violations, was 1.3 times higher at the crosswalks with the countdown timer. This research was unique because for the first time, two-phase pedestrian crossings on the roadway with the median refuge island in the sense of clearance time were analysed, in spite of the previous proof that pedestrians are more likely to commit violations during the red signal in that kind of roadway. Another novelty in the research was pedestrians following till the end of crossing, due to the possibility of subsequent violations. With the means of binary logistic regression, different factors which affect pedestrians’ behaviour during the clearance time have been determined and they differ depending on the existence of the timer. At the pedestrian crosswalks with the timer, contributing factors have been determined, such as gender, the number of waiting pedestrians, distractions, arrival time, and age. If there is no timer, the contributing factors are the following: the number of crossing pedestrians, distractions, group, position of pedestrians in relation to the vehicle, the number of traffic lanes, and age. Based on the obtained results, a new design of the pedestrian traffic lights was proposed. (shrink)

The well-known argument against the Search for ExtraTerrestrial Intelligence (SETI) due to George Gaylord Simpson is re-analyzed almost half a century later, in the light of our improved understanding of preconditions for the emergence of life and intelligence brought about by the ongoing “astrobiological revolution”. Simpson’s argument has been enormously influential, in particular in biological circles, and it arguably fueled the most serious opposition to SETI programmes and their funding. I argue that both proponents and opponents of Simpson’s argument have (...) occasionally mispresented its core content. Proponents often oversimplify it as just another consequence of biological contingency, thus leaving their position open to general arguments limiting the scope of contingency in evolution (such as the recent argument of Geerat Vermeij based on selection effects in the fossil record). They also tend to neglect that the argument has been presented as essentially atemporal, while referring to entities and processes that are likely to change over time; this has become even less justifiable as our astrobiological knowledge increased in recent years. Opponents have failed to see that the weaknesses in Simpson’s position could be removed by restructuring of the argument; I suggest one way of such restructuring, envisioned long ago in the fictional context by Stanislaw Lem. While no firm consensus has emerged on the validity of Simpson’s argument so far, I suggest that, contrary to the original motivation, today it is less an anti-SETI argument, and more an astrobiological research programme. In this research programme, SETI could be generalized into a platform for testing some of the deepest assumptions about evolutionary continuity and the relative role of contingency versus convergence on unprecedented spatial and temporal scales.
