Critical phenomena in stock exchange are regularly occurring and difficult to predict events, often leading to disastrous consequences. The presented paper is devoted to the search and research of early warning signals of critical transitions in stock exchange based on the results of a multifractal analysis of a series of transactions in shares of public companies. We have proposed and justified the use of certain features of behavior of multifractal spectrum shape parameters such as signals. As model time series, (...) on which methods of multifractal analysis were tested, we used a series of the number of unstable sites of the sandpile automaton on the random Erdős–Rényi graph, self-organizing into critical and bistable states. It was found that the early warning signals for both cellular automata and stock exchanges are an increase in the magnitude of the maximum position, a decrease in the width, and a decrease, followed by a sharp increase, in the value of the spectrum asymmetry parameter.

Our research aimed to investigate the effectiveness of auditory, visual, and audiovisual warning signals for capturing the attention of the pilot, and how stimulus onset asynchronies in audiovisual stimuli affect pilots perceiving the bimodal warning signals under different perceptual load conditions. In experiment 1 of the low perceptual load condition, participants discriminated the location of visual targets preceded by five different types of warning signals. In experiment 2 of high perceptual load, participants completed the location task identical (...) to a low load condition and a digit detection task in a rapid serial visual presentation stream. The main effect of warning signals in two experiments showed that visual and auditory cues presented simultaneously could effectively and efficiently arouse the attention of the pilots in high and low load conditions. Specifically, auditory, AV, and visual preceding auditory stimulus by 100 ms increased the spatial orientation to a valid position in low load conditions. With the increase in visual perceptual load, auditory preceding the visual stimulus by 100 ms and A warning signals had stronger spatial orientation. The results are expected to theoretically support the optimization design of the cockpit display interface, contributing to immediate flight crew awareness. (shrink)

Zusammenfassung In der öffentlichen Debatte über die Corona-Warn-App kann der Solidaritätsbegriff als wichtiger, aber inhaltlich umstrittener normativer Bezugspunkt gelten. So stehen hier unterschiedliche Solidaritätsrekurse mit heterogenen Voraussetzungen, normativen Implikationen und praktischen Konsequenzen nebeneinander, die einer medizinethischen Untersuchung bedürfen. Vor diesem Hintergrund ist es Ziel des Beitrags, _erstens_ die Bandbreite der Verwendungsweisen des Solidaritätsbegriffs in der öffentlichen Debatte zur Corona-Warn-App anschaulich zu machen sowie _zweitens_ die Voraussetzungen und normativen Implikationen dieser Verwendungsweisen herauszuarbeiten und einer ethischen Bewertung zu unterziehen. Dazu stelle ich (...) nach einer kurzen Einführung in die Corona-Warn-App und einer Vergegenwärtigung der Grundzüge des Solidaritätskonzepts vier Beispiele aus der öffentlichen Debatte zur Corona-Warn-App dar, die mit Blick auf die zugrundeliegende Identifikation, die Solidaritätsgruppe, den solidarischen Beitrag sowie das normative Ziel erhebliche Unterschiede aufweisen. Sie unterstreichen die Notwendigkeit weiterführender Maßstäbe, um ihre Legitimität zu bewerten. Dazu greife ich auf vier normative Kriterien einer kontextsensitiven, moralisch gehaltvollen Solidaritätskonzeption zurück (Solidaritätsoffenheit, gestaltbare Inklusivität, Angemessenheit des solidarischen Beitrags, normative Abhängigkeit) und evaluiere auf dieser Grundlage die vorgestellten Solidaritätsrekurse ethisch. Für alle dargestellten Solidaritätsrekurse lassen sich in der Folge kritische Rückfragen formulieren. Dabei werden einerseits die Potenziale und Limitationen von Solidaritätsrekursen in öffentlichen Debatten deutlich. Andererseits werden Schlussfolgerungen möglich, wann eine Tracing-App tatsächlich als solidarische Technologie zur Pandemiebekämpfung verstanden werden kann. (shrink)

Auditory warnings have been shown to interfere with verbal working memory. However, the impact of different types of auditory warnings on working memory tasks must be further researched. This study investigated how different kinds of auditory warnings interfered with verbal and spatial working memory. Experiment 1 tested the potential interference of auditory warnings with verbal working memory. Experiment 2 tested the potential interference of auditory warnings with spatial working memory. Both experiments used a 3 × 3 mixed design: auditory (...) class='Hi'>warning type was between groups, and task condition was within groups. In Experiment 1, earcons and spearcons but not auditory icons worsened the performance on the verbal serial recall task in the identify-warning condition, compared with that in the no-warning or ignore-warning conditions. In Experiment 2, only identifying earcons worsened the performance on the location recall task compared with performance without auditory warnings or when auditory warnings were ignored. Results are discussed from the perspective of working memory resource interference, and their practical application in the selection and design of auditory warning signals is involved. (shrink)

Focusing on media discourse and adopting a Critical Discourse Analysis—linguistic and rhetorical—perspective, this paper explores the role of the media in influencing citizens’ behaviour towards the COVID-19 crisis. The paper evaluates the set of potentially persuasive lexical items and emotional implicatures used by two quality newspapers, i.e. The Guardian and El País, to report on the pandemic during the three waves—the periods between the onset and trough of virus contamination—that occurred until March 2021. A representative, ad-hoc, comparable corpus was compiled (...) in English and Spanish comprising the news on the pandemic that appeared in the aforementioned newspapers during the three established time periods. The corpora were uploaded to Sketch Engine, which was used to first detect and analyse different categories of word frequency, and then assign negative or positive polarity. Lexical keyness was secondly analysed to categorize emotional implicatures of control, metaphors, signals of epistemic asymmetry and positive implicatures in order to discern how they become weapons of negative or positive persuasion. The ultimate end of the study was to critically analyse and contrast the lexicon and rhetoric used by these two newspapers during this time period so as to unveil the stance taken by governments and health institutions—voices of authority—to disseminate words of control and persuasion with the aim of exerting influence on the behaviour of citizens in UK and Spain.

Acoustic signals serving intraspecific communication by predators are perceived by potential prey as warning signals. We analysed the acoustic characteristics of howling of wolves and found a striking similarity to the warning sounds of technical sirens. We hypothesize that the effectivity of sirens as warning signals has been enhanced by natural sensory predisposition of humans to get alerted by howling of wolves, with which they have a long history of coexistence. Psychoacoustic similarity of both stimuli seems to (...) be supported by the fact that wolves and dogs perceive the sound of technical sirens as a relevant releasing supernormal stimulus and reply to it with howling. Inspiration by naturally occurring acoustic aposematic signals might become an interesting example of biomimetics in designing new warning sound systems. (shrink)

Computer users are often the last line of defense in computer security. However, with repeated exposures to system messages and computer security warnings, neural and behavioral responses show evidence of habituation. Habituation has been demonstrated at a neural level as repetition suppression where responses are attenuated with subsequent repetitions. In the brain, repetition suppression to visual stimuli has been demonstrated in multiple cortical areas, including the occipital lobe and medial temporal lobe. Prior research into the repetition suppression effect has generally (...) focused on a single repetition and has not examined the pattern of signal suppression with repeated exposures. We used complex, everyday stimuli, in the form of images of computer programs or security warning messages, to examine the repetition suppression effect across repeated exposures. The use of computer warnings as stimuli also allowed us to examine the activation of learned fearful stimuli. We observed widespread linear decreases in activation with repeated exposures, suggesting that repetition suppression continues after the first repetition. Further, we found greater activation for warning messages compared to neutral images in the anterior insula, pre-supplemental motor area, and inferior frontal gyrus, suggesting differential processing of security warning messages. However, the repetition suppression effect was similar in these regions for both warning messages and neutral images. Additionally, we observed an increase of activation in the default mode network with repeated exposures, suggestive of increased mind wandering with continuing habituation. (shrink)

I shall speak of ghost [revenant], of flame and of ashes.And of what, for Heidegger, avoiding means.What is avoiding? Heidegger on several occasions uses the common word Vermeiden: to avoid, to flee, to dodge. What might he have meant when it comes to “spirit” or the “spiritual”? I specify immediately: not spirit or the spiritual but Geist, geistig, geistlich, for this question will be, through and through, that of language. Do these German words allow themselves to be translated? In another (...) sense: are they avoidable?Sein und Zeit : what does Heidegger say at that time? He announces and he prescribes. He warns [avertit]: a certain number of terms will have to be avoided . Among them, spirit . In 1953, more than twenty-five years later—and this was not just any quarter-century—in the great text devoted to Georg Trakl, Heidegger notes that Trakl always took care to avoid the word geistig. And, visibly, Heidegger approves him in this; he thinks the same. But this time, it is not Geist nor even geistlich that is to be avoided, but geistig.How are we to delimit the difference, and what has happened? What of this meantime? How are we to explain that in twenty-five years, between these two warning signals , Heidegger made a frequent, regular, marked use of all this vocabulary, including the adjective geistig? And that he often spoke not only of the word “spirit” but, sometimes yielding to the emphatic mode, in the name of spirit? Jacques Derrida is Directeur d’Études at the École des Hautes Études en Sciences Sociales and also teaches at the University of California, Irvine. His most recent contribution to Critical Inquiry is “Like the Sound of the Sea Deep within a Shell: Paul de Man’s War” .

This paper distinguishes processes potentially contributing to interpersonal anxiety transfer, including object-directed social appraisal, empathic worry, and anxiety contagion, and reviews evidence for their operation. We argue that these anxiety-transfer processes may be exploited strategically when attempting to regulate relationship partners’ emotion. More generally, anxiety may serve as either a warning signal to other people about threat (alerting function) or an appeal for emotional support or practical help (comfort-seeking function). Tensions between these two interpersonal functions may account for (...) mutually incongruent interpersonal responses to expressed anxiety, including mistargeted interpersonal regulation attempts. Because worry waxes and wanes over time as a function of other people's ongoing reactions, interpersonal interventions may help to alleviate some of its maladaptive consequences. (shrink)

Health care often involves ethically difficult situations that may disquiet the conscience. The purpose of this study was to develop a questionnaire for identifying various perceptions of conscience within a framework based on the literature and on explorative interviews about perceptions of conscience (Perceptions of Conscience Questionnaire). The questionnaire was tested on a sample of 444 registered nurses, enrolled nurses, nurses’ assistants and physicians. The data were analysed using principal component analysis to explore possible dimensions of perceptions of conscience. The (...) results showed six dimensions, found also in theory and empirical health care studies. Conscience was perceived as authority, a warning signal, demanding sensitivity, an asset, a burden and depending on culture. We conclude that the Perceptions of Conscience Questionnaire is valid for assessing some perceptions of conscience relevant to health care providers. (shrink)

In general, existential threats are those that may potentially result in the extinction of the entire human species, if not significantly endanger its living population. Among the said threats include, but not limited to, pandemics and the impacts of a technological singularity. As regards pandemics, significant work has already been done on how to mitigate, if not prevent, the aftereffects of this type of disaster. For one, certain problem areas on how to properly manage pandemic responses have already been identified, (...) like the following: (a) not being able to learn from previous experiences, (b) the inability to act on warning signals, and (c) the failure to reach a global consensus on a problem (i.e., in a timely manner). In terms of a singularity, however, it may be said that further research is still needed, specifically on how to aptly respond to its projected negative outcomes. In this paper, by treating the three problem areas noted above as preliminary assessment measures of a country’s capacity to coordinate a national response to large-scale disasters, we examine the readiness of the Philippines in preparing for an intelligence explosion. By citing certain instances of how the said country, specifically its national government, faced the coronavirus disease 2019 pandemic, it puts forward the idea that the likely Philippine disaster response towards a singularity needs to be worked on, appealing for a more comprehensive assessment of such for a more informed response plan.

Moral Seduction Theory suggests that auditors are morally compromised by the perceived consequences of their opinions. The root of the auditing problem appears to result in an unintentional bias rather than in dishonesty. Although important accounting reforms have been taken to deal with auditors' trustworthiness, their lack of independence has not been adequately addressed. The new regulation (Sarbanes-Oxley Act) is a consequence of an incorrect understanding of the main true source of auditor's biases. We have developed a cognitive approach by (...) connecting the Throughput Model (TM) to the Moral Seduction Theory. This approach allows a better understanding of how conflicts of interest lead auditors to avoid the issuance of warning signals to stakeholders. We have tested our model by conducting a hypothetical scenario with eighty experienced auditors from international accounting firms. Our results confirm auditors' unintentional reluctance to issue qualified audit opinions alerting investors due to their fear of precipitating clients' final bankruptcy. The main implication is that, more than a regulation, effort should be made in monitoring those conflicts of interest to reduce unintentional bias. (shrink)

Several critics have reopened the continuing debate regarding the credibility of the auditing profession in part because of auditors' reluctance to issue warning signals to investors. At the root of auditors' lack of independence issues are conflicts of interest resulting from the structural features of auditor-client relationship. The Throughput Model is advanced to illustrate how ethical issues may be influenced by conflicts of interest. In the first stage, the TP provides an isolation of auditors' ethical positions from six ethical (...) different perspectives. In the second stage, previous TP theory is built upon by arguing a simultaneous analysis of how conflicts of interests may induce auditors' behavior. We conclude that in the current low litigation risk environment, auditors' ethical behavior is clearly ' unbalanced' favoring the reluctance to issue warning signals. Finally, we offer a discussion of potential solutions to improve ethical issues. (shrink)

The ability to detect and respond to chemosensory threat cues in the environment plays a vital role in survival across species. However, little is known about which chemical compounds can act as olfactory threat signals in humans. We hypothesized that brief exposure to putrescine, a chemical compound produced by the breakdown of fatty acids in the decaying tissue of dead bodies, can function as a chemosensory warning signal, activating threat management responses (e.g., heightened alertness, fight-or-flight responses). This hypothesis (...) was tested by gaging people’s responses to conscious and non-conscious exposure to putrescine. In Experiment 1, putrescine increased vigilance, as measured by a reaction time task. In Experiments 2 and 3, brief exposure to putrescine (vs. ammonia and a scentless control condition) prompted participants to walk away faster from the exposure site. Experiment 3 also showed that putrescine elicited implicit cognitions related to escape and threat. Experiment 4 found that exposure to putrescine, presented here below the threshold of conscious awareness, increased hostility toward an out-group member. Together, the results are the first to indicate that humans can process putrescine as a warning signal that mobilizes protective responses to deal with relevant threats. The implications of these results are briefly discussed. (shrink)

While jurisprudence in the United States has been cast in the general mode of the English common law, modifications over time have produced enough significant variations that American law has a distinctive quality. To illustrate: The exclusionary rule in criminal cases prohibiting the use of evidence (even from reliable witnesses) acquired through illegal search, is not followed in Britain—or, for that matter, in Canada, Germany, and Israel. The punitive-damage concept (PD) in tort law is also a jurisprudential novelty. Punitive damages (...) are imposed in addition to compensatory awards given to tort victims to warn manufacturers and sellers to be careful in their safety and marketing practices. PDs are society's warning signals: Seller beware! Because they are one of society's ways to protect itself, PDs have recently been considered as fines which, to prevent excesses, should be under the rubric of the Eighth Amendment.This essay introduces new elements into the discussion on torts by hypothesizing (1) PDs are fines which belong to the public purse; (2) that expenditures from the public purse should be given to local organizations (like orphanages and inner-city hospitals) which provide vital services for those unable to pay; and (3) that the victim (or the victim's survivor) has a right to designate what local organizations should benefit from his or her punitive-damage awards.The hypotheses require reexamination of the concepts of citizenship, community, and work, respectively.Tort law is an integral part of the American law of injuries, a body of judicial doctrine and legislation and a set of legal arrangements that also include compensation systems and safety legislation. It would have been unthinkable as recently as twenty-five years ago that the tort system would become a source of bitter contention. Today, however, it generates sharp rhetoric and dramatic proposals for change to address its contested problems, as well as strong views in favor of continuing the system essentially intact so as not to disturb its contended benefits.

Most land plants associate with mycorrhizal fungi that can connect roots of neighboring plants in common mycelial networks (CMNs). Recent evidence shows that CMNs transfer warning signals of pathogen and aphid attack between plants. However, we do not know how defence‐related signaling via CMNs operates or how ubiquitous it is. Nor do we know what the ecological relevance and fitness consequences are, particularly from the perspective of the mycorrhizal fungus. Here, we focus on the potential fitness benefits for mycorrhizal (...) fungi and outline hypothetical scenarios in which signal transfer via CMNs is modulated in order to acquire the most benefit for the fungus (i.e. acquisition of carbon) for minimal cost. We speculate that the signal may be quantitative and may elicit plant defence responses on different levels depending on the distance the signal is transferred. Finally, we discuss the possibility of practical applications of this phenomenon for crop protection. (shrink)

Telecommunications is one of the most dynamic sectors in the market, where the customer base is an important pawn in receive safe revenues, so is important to focus attention is paid to maintaining them with an active status. Migrating customers from one network to another varies among telecommunication companies depending on different factors such as call quality, pricing plan, minute consumption, data, sms facilities, customer billing issues, etc. Determining an effective predictive model helps detect early warning signals when churn (...) occurs and assigns to each customer a score called “churn score” that indicates the likelihood that the individual might migrate to another network over a predefined time period. To this extent, the present paper uses more than 10k customers sample of a telecommunication company and tries to analyse the churn behavior. The aim of the paper is both to test the efficiency and performance of the most commonly used data mining techniques to predict the churn behavior and to underline the main indicators that can be used when conducting such analyses. Knowing the magnitude of the churn phenomenon, the company can prevent the instability that is going to occur by applying a series of measure in order to increase the retention of the current customers.

The participants in the present study had to make speeded elevation discrimination responses to visual targets presented to the left or right of central fixation following the presentation of a task-irrelevant auditory cue on either the same or opposite side. In Experiment 1, the cues were presented from in front of the participants (from the same azimuthal positions as the visual targets). A standard crossmodal exogenous spatial cuing effect was observed, with participants responding significantly faster in the elevation discrimination task (...) to visual targets when both the auditory cues and the visual targets were presented on the same side. Experiment 2 replicated the exogenous spatial cuing effect for frontal visual targets following both front and rear auditory cues. The results of Experiment 3 demonstrated that the participants had little difficulty in correctly discriminating the location from which the sounds were presented. Thus, taken together, the results of the three experiments reported here demonstrate that the exact co-location of auditory cues and visual targets is not necessary to attract spatial attention. Implications of these results for the design of real-world warning signals are discussed. (shrink)

Strikingly, theorizing about digital technologies has led us to recognize many habitual subjects of research as figures against fields that are also worthy of study. Communication, for example, becomes visible only against the field of silence. Silence is critically important for the construction of reality – and the social construction of reality has a complement, the also necessary contemplative construction of reality. Silence is so sensitive and fragile that an inability to achieve it, or to get rid of it, or (...) to correct the wrong kind of silence often provides early indicators of individual, group, communal, and society-wide stresses from information technologies. Indeed, we might treat difficulties with silence as miners treated canaries in coal mines, as early warning signals. The story has already been told that nightingales in London now have to sing so loudly in order to be heard above the ambient noise that the birds are in danger of breaking the noise ordinance law. Surely something has gone awry if nightingales break the law when they sing. Finding ways to protect silence as an arena of personal and social choice is a particularly poignant, evocative, and instructive ethical and policy horizon at this frontier moment for the human species. This article introduces the theory of the contemplative construction of reality, explores what the study of silence tells us about reality construction processes, and outlines a research agenda.

As a general rule, whenever a hearer is justified in forming the belief that p on the basis of a speaker’s testimony, she will also be justified in assuming that the speaker has formed her belief appropriately in light of a relevantly large and representative sample of the evidence that bears on p. In simpler terms, a justification for taking someone’s testimony entails a justification for trusting her assessment of the evidence. This introduces the possibility of what I will call (...) “evidential preemption.” Evidential preemption occurs when a speaker, in addition to offering testimony that p, also warns the hearer of the likelihood that she will subsequently be confronted with apparently contrary evidence: this is done, however, not so as to encourage the hearer to temper her confidence in p in anticipation of that evidence, but rather to suggest that the (apparently) contrary evidence is in fact misleading evidence or evidence that has already been taken into account. Either way, the speaker is signalling to the hearer that the subsequent disclosure of this evidence will not require her to significantly revise her belief that p. Such preemption can effectively inoculate an audience against future contrary evidence, and thereby creates an opening for a form of exploitative manipulation that I will call “epistemic grooming.” Nonetheless, I argue, not all uses of evidential preemption are nefarious; it can also serve as an important tool for guiding epistemically limited agents though complex evidential scenarios.

Neurobiological and cognitive models of unconscious information processing suggest that subconscious threat detection can lead to cognitive misinterpretations and false alarms, while conscious processing is assumed to be perceptually and conceptually accurate and unambiguous. Furthermore, clinical theories suggest that pathological anxiety results from a crude preattentive warning system predominating over more sophisticated and controlled modes of processing. We investigated the hypothesis that subconscious detection of threat in a cognitive task is reflected by enhanced ''false signal'' detection rather than (...) by selectively enhanced discrimination of threat items in 30 patients with panic disorder and 30 healthy controls. We presented a tachistoscopic word-nonword discrimination task and a subsequent recognition task and analyzed the data by means of process-dissociation procedures. In line with our expectations, subjects of both groups showed more false signal detection to threat than to neutral stimuli as indicated by an enhanced response bias, whereas indices of discriminative sensitivity did not show this effect. In addition, patients with panic disorder showed a generally enhanced response bias in comparison to healthy controls. They also seemed to have processed the stimuli less elaborately and less differentially. Results are consistent with the assumption that subconscious threat detection can lead to misrepresentations of stimulus significance and that pathological anxiety is characterized by a hyperactive preattentive alarm system that is insufficiently controlled by higher cognitive processes.

Food producers have answered increasing consumer demand for transparency through disclosure of information on food labels. Food safety labels act as a signal to consumers that certain products may pose a risk to human health. These labels are based on developments in microbiology and/or represent a required response to foodborne illness outbreaks. However, the scope of the risk posed by product consumption, as well as who is most vulnerable to harm, varies based on the ethical reasoning underlying the presence (...) of the label on the package. This paper applies Thompson (International Journal of Food Science and Technology 36: 833–843, 2001)‘s theory on two contrasting ethical approaches to risk communication – choice optimization and informed consent – to evaluate the four most common food safety labels in the US: i) unpasteurized juice warnings; ii) egg carton safe handling instructions; iii) consumer advisories on restaurant menus; and iv) date labeling. While the choice optimization approach dictates that food safety labels are a necessary tool to equip consumers with specific information that will promote public health (i.e., egg carton safe handling instructions), informed consent obliges producers to disclose all relevant risk information so consumers can choose one product or another based on its adherence to individual values (e.g., unpasteurized juice; undercooked animal products). This paper finds that the US food safety regime represents a blending of these two ethical foundations, leading to substantial variation in risk consumer tolerance and/or aversion. One effect of the intermingling of these two ethical approaches is choice overload among consumers for newer food safety labels (e.g., date labels). This paper concludes with a discussion of policy prioritization in the context of an increasingly crowded food label marketplace. (shrink)

Structure learning algorithms for graphical models have focused almost exclusively on stable environments in which the underlying generative process does not change; that is, they assume that the generating model is globally stationary. In real-world environments, however, such changes often occur without warning or signal. Real-world data often come from generating models that are only locally stationary. In this paper, we present LoSST, a novel, heuristic structure learning algorithm that tracks changes in graphical model structure or parameters in (...) a dynamic, real-time manner. We show by simulation that the algorithm performs comparably to batch-mode learning when the generating graphical structure is globally stationary, and significantly better when it is only locally stationary.

In Homer’s account of the adventurous journey of Odysseus, the song of the sirens was so appealing and tempting that it lured sailors to their deaths. Warned by the goddess Kirke, Odysseus overcame the trap by plugging his crew’s ears with wax. An archaeo-acoustical research expedition undertaken by members of Humboldt University Berlin made sound propagation experiments at the supposedly historical scene at the Galli Islands where it’s said that the sirens originally sung. At the site we broadcasted both synthetic (...) signals and natural voices via loudspeakers in the direction Odysseus most probably should have approached the Siren’s island. Subjective listening as well as objective acoustic analysis of the recorded signals revealed evidence for a combination of site-specific acoustic effects, which may explain the nature and origin of the song of the sirens in Homer. The local arrangement of the three islands deforms the acoustic signals by amplification and by changes in timbre. Two female singers from the Berlin State Opera were asked to sing differently pitched musical intervals to be tested in the Li Galli environment. The experiment evinced that the first overtones would be merged by the echo of the rocks; yet when singing pure thirds and less consonant intervals, which yield higher orders in the overtone series, the voices appear recognisable as being two. As a result, and particularly because Homer stresses the number of exactly two sirens several times, the evidence of our research supports the musicological theory for a rather early existence of enharmonic tunings and most prominently a two-part polyphonic singing of Greek songs. Given that the rocky formation of the Galli Islands most likely didn’t change during the geological tick of just 2,700 years, we conclude that there has been a real acoustic basis for the myth reported by Homer and that a “song of the Sirens”, most probably based on natural voices, was transformed by the particular acoustic conditions of the landscape in such a way that signals were amplified and sent out in one concrete direction. Based on these results, we continue to discuss further leading acoustic theories that offer new insights into the mythology and which were essential to motivate our expedition in the first place. After all, the question remains open what kind of beings the first emitters of the song might have been. (shrink)

All is set for the Greeks' departure from Troy. As I understand the scene, the rowers have their oars strapped to their hands and are eager to start. A warning flare now shines out from the regia ratis and the actual signal to start is given by a trumpet-blast, either rhetorically viewed as addressed to the thousand ships from the flagship or sounded on each at sight of the flare. The flagship then moves off and is followed by (...) the fleet. Cf. the related passage, Tro. 1044–6 ‘cum tuba iussi dare uela nautae | et simul uentis properante remo | prenderint altum’.428 laetum was conjectured by Leo in view of the difficulty of reconciling lentum, which would normally mean ‘listless’ or ‘sluggish’, and properanti in 426 ; note too 437 ff. ‘properat iuuentus omnis adductos simul | lentare remos…’ and the expression properante remo in Tro. 1045. The simple correction laetum would appear both to remove the difficulty and to be entirely appropriate. Yet, though accepted by Peiper-Richter and Herrmann, laetum has come in for resistance: it is rejected by Moricca, Viansino, Giardina, and Tarrant. In defence of lentum Viansino compares Medea 623 portibus lentis, in which I find no relevance; F. Giancotti interprets that the men in their impatience to be off appear lenti to themselves; Tarrant renders ‘slow to respond’, explaining ‘the rowing of the men is uncoordinated after ten years' lack of practice’, but in 428 the rowing has not yet started, and note the harmony indicated in 437–9. lentum is alien to Seneca's spirited picture and seems to me indefensible; laetum, on the other hand, is both attractive in itself and supported by significant evidence, which I have not seen adduced.

Plants have evolved systems analogous to animal innate immunity that recognise pathogen‐associated molecular patterns (PAMPs). PAMP detection is an important component of non‐host resistance in plants and serves as an early warning system for the presence of potential pathogens. Binding of a PAMP to the appropriate pattern recognition receptor leads to downstream signalling events and, ultimately, to the induction of basal defence systems. To overcome non‐host resistance, pathogens have evolved effectors that target specific regulatory components of the basal defence (...) system. In turn, this has led to the evolution in plants of cultivar‐specific resistance mediated by R proteins, which guard the targets of effectors against pathogen manipulation; the arms race continues.

In the face of continuing assumptions by many scientists and journal editors that p-values provide a gold standard for inference, counter warnings are published periodically. But the core problem is not with p-values, per se. A finding that “p-value is less than α” could merely signal that a critical value has been exceeded. The question is why, when estimating a parameter, we provide a range (a confidence interval), but when testing a hypothesis about a parameter (e.g. µ = x) (...) we proceed as if “=” entails exact equality of the parameter with x. That standard is hard to meet, and is not a standard expected for power calculations, where we are satisfied to reject a null hypothesis H0 if the result is merely “detectably” different from (exact) H0. This paper explores, with resampling (simulation) methods, the impacts on p-values, and alternatives, if the null hypothesis is defined as a thick or thin range of values. It also examines, empirically, the extent to which the p-value may or may not be a good predictor of the probability that H0 is true, given the distribution of the data. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Five Poems AMIT MAJMUDAR Observing Orpheus I hear the meaning turn back in his throat like Eurydice on the way up from the darkness. Music’s meaning is its making. As for me, I am one more animal in his entourage, learning a new thirst, finding a new south. None of us knew we had this instinct in us. If deserts hide wildflowers until first rain, bright ears are blossoming (...) out of our skulls. He doesn’t have much longer. I know this myth. A God douses the fire with a beehive. The Maenads smear their faces with a warpaint made of stoneground fireflies and pine sap. Hands—hands like his, that drew music through lyre strings into our forest like pieces of bread through a prison fence— are reaching for his body now, his lyre. Their weapons are hands, nothing but hands. They are infinite. They are enough. arion 27.1 spring/summer 2019 Her Metamorphoses First a beetle, body armor forged of chitin, exoskeleton he’ll never bruise, Undiscovered, unapologetically hermetic on her own Galapagos. Next a fruit bat, echolocating tangerines like a blind woman singing up at stars. Then a patio lizard, sunning herself for as long as she needs, A better place for keeping warm than bed with him. Next a sleek water moccasin, quick to make out another woman’s heat signature on his neck, Even quicker to strike. A caterpillar to poke holes in his lying roses And from that destruction to fashion two beautiful wings for herself. A buzzard, to clean up the roadside pile he left of her. A woman in full with no more soft blind pupa stages of her life cycle left, No more forms to force herself to fit for the sake of his pleasure, No more shapeshifts, no more slimming stripes, no more abdominal crunches: Just this body, just this last name, just this apartment, just this bowl of midnight cereal. Just her. 106 five poems Sisyphus Shove hard, shove, shove hard, eyes bloodshot, knees bent Till your boulder goes weightless and races ahead in descent. Force its dark door open inch by grim inch, Shove hard, shove, shove hard, eyes bloodshot, knees bent, Heels dug deep in hell’s steep hillside, teeth clenched. What gravity strips from you, gravity grants you again. Shove hard, shove, shove hard, eyes bloodshot, knees bent Till your body goes weightless and races ahead in ascent. Amit Majmudar 107 A Trinket for Persephone A deathwatch beetle burrows in the pale hall of your marrow, your underground, your tube of bone on which you’re riding home alone. This blackwinged locket with your soul emerges rattling from a hole, a rattle in your emptied throat, the diva’s final, graceless notes, a clicking echoed in the rafters, this bugbear insect coming after to scuttle across the marshy chest, sinkhole navel, and pubic nest out to the yard, below the porch untrackable by any torch until this bug with you inside has burrowed to the other side. It drops into the underworld, as if from some cocoon unfurled, to scale a queenly wrist and rest your brooch of black upon her breast. 108 five poems Four Ways of Looking at Argus 1. His Vigil These hundred eyes, these hundred balloons Tied to the boy-small wrist of my mind Are down to ninety-nine. I lost one to a bee sting late last June— I never thought of them as fragile Until that pinprick broke my vigil. I’m slowing down. I didn’t blink in time. I have no inkling why I keep This vigil—surely not to watch, Panoptic from this mountaintop, A heifer drifting off to sleep? I’m here, I must be here, to see A signal fire from the east That warns of Olympus under siege And Ares gory from a rout, Athena’s owl’s eyes gouged out, The naiads naked in a pen, The whole world given up to men. The Gods will need a monster then. 2. After Martial Hermes was in a fix: He needed lullabies To shutter Argus’s one hundred eyes And get the tethered heifer—coal-eyed Io—free Of Hera’s... (shrink)

In the last chapter of In the beginning was the deed: realism and moralism in political argument, Williams raised the question of truthfulness in politics and warned that the media, particularly, television, and the market of communication in general, work in ways contrary to truthfulness -understood as the combination of the virtues of sincerity and accuracy. In this paper we would like to carry on Williams’ line of thinking in connection with the impact of the new social media platforms on (...) politics. Where Williams focused on television, we will consider the impact of the internet public sphere. After reviewing how the digital social media encourages motivated reasoning in general, we propose to focus on two main phenomena derived from it: the rise of conspiracy theories and the moralization of politics. Conspiracy theories epitomize the risk of self-deception Williams was concerned to signal. On the other hand, the process of moralization of politics triggers sectarianism and hate for the “others”, the outgroup. Both phenomena are not exclusive of the internet sphere, but both are boosted by it, and entail a lack of interest in truth and truthfulness, and in this way they threaten the value of truth for democracy.

In lieu of an abstract, here is a brief excerpt of the content:Rules and CommunityJeffrey Bedrick, MDThe paper, “The Dilemma of Compliance: Roles and Rules in Schizophrenia, Censorship, and Life,” by Riley Paterson raises a number of interesting issues. I am only able to address a few of these issues here, and I do so in the hope of broadening our consideration of some of the basic concerns.Paterson focuses his attention on the potentially repressive side of rules, even while acknowledging (...) the broader role of rules in human life. Thus, towards the end of his paper he writes “While I regard all experience as rule- and role-bound, the aforementioned groups”—those who “experience schizophrenia, persecution, or are otherwise marginalized and vulnerable”—“experience rules and roles with particular violence.” He admirably warns us to be sure that in our work with people we are not traumatizing or re-traumatizing them.But rules play a broader role in human life. Paterson discusses censorship and the role that rules can play in repressing the expression of ideas. But rules also allow the use of language and govern communication in general. Writers living under censorship resorted, Paterson notes, to a system of exoteric and esoteric writing and communication. But those esoteric texts, if they were not to remain purely private and unknowable to those who read the texts, had to follow certain rules and conventions to signal the reader that the exoteric text was not all there was, and that there was another, esoteric, meaning to be found within the text. Writing under conditions of censorship remained a communal, intersubjective, endeavor.With schizophrenia, the seeming central topic of the paper, the situation becomes even more complex. We shall see that Paterson’s analyses point us in two different directions.Paterson writes:In schizophrenia we see an exaggerated instance of the dilemma raised above: There is a gap that exists between the publicly available roles, and the person we feel ourselves to be. We are required to conform with the demands of these roles to preserve what we feel most natural in ourselves. People with schizophrenia often must conceal, at times, their experiences of hallucinations and delusions in order to preserve some ability for social interaction. In my clinical work, however, people with schizophrenia have often reported it has felt freeing to learn when and with whom they can share those thoughts and experiences. Freeing, not because they need to hide part of themselves but because doing so opens up possibilities of social interaction and community.Further, Paterson writes of the difficulties people with schizophrenia may have with ‘weintentionality.’ Referencing Salice and Henriksen (2021) [End Page 381] he concludes that “the self-disorders of schizophrenia preserve a capacity for joint intentionality (rule following) but severely inhibit an experience of group belonging and identity (weintentionality).” Indeed he notes, again following Salice and Henriksen (2021), “that some individuals experiencing more mild forms of schizophrenia spectrum disorders found great comfort and safety in rule following.” The problem for people with schizophrenia thus seems less with applying specific rules, which might in some cases be meant to regulate or repress behavior, than in establishing we-intentionality. Many phenomenologists have explored the concept of intersubjectivity and have noted, as have many psychoanalysts and therapists, that there is no pure, interior subject but that our very selfhood is formed in interaction and relation to others. (See, for one example, the work of Alfred Schutz (1967) for a phenomenological investigation of intersubjectivity and the social.) To borrow Paterson’s gardening metaphor, there are no sole, beautiful flowers. They must be cared for to grow, or be part of a natural ecosystem that allows them to flourish.Cognitive and negative symptoms are widely accepted as posing more of a burden to schizophrenia than the more flamboyant hallucinations and delusions. These seem to me to be due less to a difficulty conforming or complying to social rules that may be felt to be restrictive or repressive and more due to the difficulties with intersubjectivity and we-intentionality. The people I have worked with who were most limited by their schizophrenia in my judgment have been people with severe thought disorders who demonstrated severe loosening of associations and word salad. I say... (shrink)

The Qur’an, a divine book, is a source whose authority is indisputable in terms of being a source of knowledge for Muslims and setting the framework of “speaking” about God and also allowing for the determination of what is moral. The Qur’an’s authority derives from both God Himself and the intra-textual consistency. Reasonal and philosophical justification of such values as freedom, creation, reason, wisdom, endeavor, reliability, and particularly unity of God have been dwelled upon in the present article. At the (...) same time, the visible effects of the aforementioned concepts, which are of great significance in themselves, in the external world, have been examined with their notional immanence and with the exemplarity of the Prophet. It is emphasized that absolute determinism, moral nihilism, and other materialistic views that accept the eternal existence of matter with the Creator lead to a worldview that suspends the freedom of choice and, in particular, the freedom of choosing a religion for humans. As Mu‘tazilah rightly argued in this regard, the essential condition of attaching value to an occurrence is that it must take place in an environment of freedom. The present article signalizes the way to achieve the theory, which we have named as Kalam’s Theory of Freedom, by drawing attention to the existence of some values that can also be reached through sole reason and rationalism intrinsic to the kalam discipline. Ultimately, it illuminates the path where the multicultural world can be a home for all of us without coercion and discrimination. Actions expected to attain their purposes and rationalism considering the possible outcomes of actions, especially pluralist and libertarian education processes, do not allow for ‘a single-valued world’ and nihilism. Qur’an’s warning about chaos is explicit for societies losing their religious, rational, and moral values. (shrink)

The emergence of conflicts between environmental safety incidents and protection rights generates sizeable political costs, which endangers the legitimacy of the government as well as political security and stability. This article further examines the role of political costs in environmental issues. First, political costs in relation to environmental issues are defined. An equilibrium strategic analysis is then presented using an evolutionary game model in which the strategic behavioral choices of government, enterprises, and citizens are investigated by embedding political costs in (...) the environmental governance system. Furthermore, the small-signal model was innovatively applied to simulate and analyze the stability of political costs under different equilibrium strategies in the system. The results show the following. Pubic behavior and government are the dominant factors that impact stability and instability, respectively. Public behavior is the core element that affects political cost consumption. When political costs are extremely depleted, the public will neglect economic interests, turn toward environmental interests, and choose the negative participation strategy, which destabilizes the system. The political cost signal at the optimal equilibrium point not only warns the government not to take the desperate action of concealing information asymmetry but also allows the government to let go of its hands to deal with the environmental issues. Corresponding policy recommendations are proposed. (shrink)

In a recent JME article, Guidry-Grimes, Dean and Victor offer some signal and challenging insights into the ethical analysis of covert medication and in particular when administered via food. They warn of impacts on identity likely to emerge from using food in this way. In particular, they caution against allowing families to be involved in covert medication, in the light of their central role in sustaining identity. Their analysis has particular purchase in resource rich contexts and those contexts where (...) individual identity is a central concern. But it is less clear that the article’s insights are relevant to other contexts. This article places the analysis of covert medication and identity in a wider context, arguing both that the focus on identity is equally significant when analysing potential alternatives to covert medication, such as coercion; and that the ethical analysis of covert medication offered by Guidry-Grimes, Dean and Victor lacks global applicability. It seems to lack application particularly in resource-poor contexts, and in cultures where identity and community are interconstituted. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:On the NoseDavid F. Bell (bio)I recently underwent a COVID test. As the technician inserted the rather ominous cotton-tipped probe into my nostril, she told me that it was going to feel as if she were tickling my brain. Indeed… This experience, shared by many during the past three years, and likely multiple times, prompted me to think about my nose. Not since cocaine reentered American mainstream culture in (...) the 1970s and '80s—and found its way into countless movies that reflect the trend—has the nose been so central to a certain state of public life. It's difficult to find a film dealing with American culture from that period and beyond, from Scarface to The Wolf of Wall Street, in which there is not a scene depicting characters snorting the obligatory line or spoon of cocaine. Yes, snorting, sniffing, sneezing, ingesting the line through the nose and finishing leftover dust by collecting it with a moist finger, rubbing it lovingly against the front gum of the mouth. Freud's "Über Coca" looms ominously in the background, the work of a phase in Freud's professional career complicated by his obscure relationships with Parke-Davis (now a subsidiary of Pfizer) and Merck, pharmaceutical companies that supplied him with early samples to tickle his nose (Freud; Merkel). The Sacklers of the moment. In our day, Pfizer wants to transform our noses into defenses against the virus rather than conduits toward mind-altering dreams. In the wake of the Freud and William Halsted cocaine addictions chronicled by Howard Merkel, the irony of the contemporary link between Pfizer and the nose is patent.The nose: that orifice through which the virus creeps, the first stage in breathing, the first filter for air-borne pollutants. Recently, important immunological analyses of COVID have focused on the question of viral load, how much virus is necessary to overcome the nose's filtering function and reach the deeper airways leading to the lungs. The processes triggered by any of the major vaccines prepare antibody blueprints and actual antibodies that can be dispatched to the linings of the nose to counter the virus as soon as the body detects its presence. The Delta, Omicron, and subsequent variants remind us that the virus has mechanisms to challenge this response, namely, increased viral load that intensifies transmissibility and the potential to overwhelm antibodies. It seems, however, that [End Page 231] so-called breakthrough infections are still well controlled by the body's vaccinated immune system. Hysteria about the dangers of such incursions is partially a product of biased and often incorrect or incomplete media coverage of the COVID vaccine, which has terrified the vaccinated and fueled the skepticism of the unvaccinated.The virus tries to overpower and confuse the filtering nose in another way, more immediately apparent to our conscious selves. As many as eighty-five percent of COVID infections result in the loss of smell, generally recovered in about two to three weeks in sickened people who overcome the infection. About five percent of COVID victims, however, have not recovered their sense of smell six months or more after they have shed the virus.1 What might it mean to lose one's sense of smell? In our vision-oriented culture, both sound (the ear) and smell (the nose) have been less recognized as primary defense mechanisms than in other cultures. When one hears a sound, the first reaction is to prepare for a threat, before the sonic source is seen or understood. Orientation in the world, knowing from which direction the sound emanates, is key to preparing the body for an encounter with an unknown phenomenon: "To sound (an alarm) means to warn. Isn't any emerging sound understood as a warning? Any unexpected sonic occurrence is seen as an indication of something that is to come and that must be clarified rapidly" (Deshays 34). By the same token, to sample surroundings by sniffing what is in the air signals whether one should inhale or somehow try to hold one's breath in search of cleaner, more palatable air. Without olfaction, we are at potentially heightened risk of asphyxiation. We are more likely to... (shrink)

Readers beware! This book is other than it first seems. Ludwig Wittgenstein’s latest philosophical offering is unlike anything that we have had from him to date. Its preface warns that the Tractatus is no textbook. This is an extreme understatement; really it is a deep puzzle—one that must be handled with great care. As the first lines signal there has been a radical change in the author’s characteristic style. Gone are the ingenious, probing explorations of topics undertaken in his (...) highly fragmentary writings that have been Wittgenstein’s trademark to date. In his new book Wittgenstein abandons the interrogative that his signature vision of and approach to philosophy found in his many masterpieces—The Blue and Brown Books, The Philosophical Investigations, and On Certainty. His previous masterworks have prosecuted a continuous philosophical enterprise designed to expose, resist and reject certain deeply compelling pictures that attract, mesmerize and blind us when it comes to thinking ..
