The primary quantum mechanical equation of motion entails that measurements typically do not have determinate outcomes, but result in superpositions of all possible outcomes. Dynamical collapse theories (e.g. GRW) supplement this equation with a stochastic Gaussian collapse function, intended to collapse the superposition of outcomes into one outcome. But the Gaussian collapses are imperfect in a way that leaves the superpositions intact. This is the tails problem. There are several ways of making this problem more precise. But many authors dismiss (...) the problem without considering the more severe formulations. Here I distinguish four distinct tails problems. The first (bare tails problem) and second (structured tails problem) exist in the literature. I argue that while the first is a pseudo-problem, the second has not been adequately addressed. The third (multiverse tails problem) reformulates the second to account for recently discovered dynamical consequences of collapse. Finally the fourth (tails problem dilemma) shows that solving the third by replacing the Gaussian with a non-Gaussian collapse function introduces new conflict with relativity theory. (shrink)

The classical Halpern–Läuchli theorem states that for any finite coloring of a finite product of finitely branching perfect trees of height ω, there exist strong subtrees sharing the same level set such that tuples in the product of the strong subtrees consisting of elements lying on the same level get the same color. Relative to large cardinals, we establish the consistency of a tail cone version of the Halpern–Läuchli theorem at a large cardinal (see Theorem 3.1), which, roughly speaking, (...) deals with many colorings simultaneously and diagonally. Among other applications, we generalize a polarized partition relation on rational numbers due to Laver and Galvin to one on linear orders of larger saturation. (shrink)

Classical mutations at the mouse Brachyury (T) locus were discovered because they lead to shortened tails in heterozygous newborns. no tail (ntl) mutants in the zebrafish, as their name suggests, show a similar phenotype. In Drosophila, mutants in the brachyenteron (byn) gene disrupt hindgut formation. These genes all encode T-box proteins, a class of sequence-specific DNA binding proteins and transcription factors. Mutations in the C. elegans mab-9 gene cause massive defects in the male tail because of failed fate (...) decisions in two tail progenitor cells. In a recent paper, Woollard and Hodgkin1 have cloned the mab-9 gene and found that it too encodes a T-box protein, similar to Brachyury in vertebrates and brachyenteron in Drosophila. The authors suggest that their results support models for an evolutionarily ancient role for these genes in hindgut formation. We will discuss this proposal and try to decide whether the gene sequences, gene interactions and gene expression patterns allow any conclusions to be made about the rear end of the ancestral metazoan.

I review the modal interpretation of quantum mechanics, some versions of which rely on the biorthonormal decomposition of a statevector to determine which properties are physically possessed. Some have suggested that these versions fail in the case of inaccurate measurements, i.e., when one takes tails of the wavefunction into account. I show that these versions of the modal interpretation are satisfactory in such cases. I further suggest that a more general result is possible, namely, that these versions of the modal (...) interpretation never encounter the sort of trouble that has been claimed to arise in the case of inaccurate measurement.

Due to the advent of deglobalization and regional integration, this article aims to adopt LASSO-based network connectedness to estimate the multiscale tail risk spillover effects of global stock markets. The results show that tail risk varies across frequencies and shocks. In static analysis, the risk is centered mostly on the developed European and North American markets at a low frequency, and regionalization is imposed on the moderate frequency. Moreover, emerging markets could be sources of risk spillover, especially at (...) the highest frequency where there is no absolute risk center. In dynamic analysis, we use rolling window estimation and find that different frequencies identify distinct episodes of shocks, which provides us with the reason for the diverse risk centers at different time scales in static analysis. Our findings provide heterogeneous financial practitioners, regulators, and investors with diverse characteristics of stock markets under multiple time horizons and help them operate their own trading strategies.

Resumen: En muchas lenguas las cláusulas adverbiales iniciales presentan una repetición del predicado de la oración anterior, lo que se conoce como enlace tail-head. Este trabajo busca describir las construcciones de eth del quichua santiagueño de acuerdo con dos parámetros: a) el grado de solapamiento semántico entre los predicados de la construcción de eth, y b) el grado de integración eventiva de la adverbial inicial con la cláusula principal. El primer parámetro permite identificar construcciones verbatim -con repetición exacta del (...) verbo anterior- y no verbatim -sin repetición exacta-. El segundo parámetro se manifiesta en la forma que adopta la cláusula “cabeza”. Así, se identificaron, por un lado, una forma converbal y, por el otro, cláusulas con los sufijos del sistema de conmutación de la referencia. La interacción entre estos dos parámetros muestra que las diferentes construcciones de eth poseen diversas funciones discursivas, en particular para la coherencia temática.: In many languages preposed adverbial clauses repeat the previous verb or predicate, which phenomenon has been termed tail-head linkage. This paper aims to describe THL constructions in Santiagueño Quichua according to two parameters: a) the degree of semantic overlap between the predicates of the THL constructions, and b) the degree of event integration of the preposed adverbial with its main clause. The first parameter allows the identification of verbatim constructions -with exact repetition of the previous predicate- and non verbatim constructions -without exact repetition-. The second parameter manifests itself in the form the head clause might adopt, where it is a converb or it takes switch reference suffixes. The interplay of both parameters shows that the different THL constructions possess diverse discourse functions, particularly regarding thematic coherence. (shrink)

We outline the proof of the consistency that there exists a saturated tail club guessing ideal on ω₁ which is not a restriction of the nonstationary ideal. A new class of forcing notions and the forcing axiom for the class are introduced for this purpose.

A pilot study examined the relationship in daily life between companion animal guardianship and peoples' laughter. The study divided participants into 4 mutually exclusive groups: dog owners, cat owners, people who owned both dogs and cats, and people who owned neither. For one day, participants recorded in "laughter" logs the frequency and source of their laughter and the presence of others when laughing. Dog owners and people who owned both dogs and cats reported laughing more frequently than cat owners, as (...) did people who owned neither. The most frequent source of laughter was spontaneous laughter resulting from a situation. People who owned both dogs and cats reported most frequent spontaneous laughter resulting from an incident involving a pet. Dog owners reported less; cat owners, the least. Dog owners and people who owned both dogs and cats reported laughing more frequently in the presence of their pets than did cat owners. Findings suggest a complex relationship between pet ownership and laughter. Dogs may serve as friends with whom to laugh or their behaviors may provide a greater source of laughter. (shrink)

The GRW theory is a recent attempt to solve the measurement problem in quantum mechanics, and the tails problem is a well-known and potentially fatal criticism of the GRW theory. The first half of the paper is an exposition of the measurement problem, the GRW theory, and the tails problem. In the remainder of the paper, two methods of dealing with the tails problem are considered: first, altering the GRW theory so as to avoid the tails problem; and second, denying (...) that the tails problem is more than a novel aspect of a universal vagueness in the way scientific theories relate to everyday language.

Eukaryotic genomes harbor a large number of homologous repeat sequences that are capable of recombining. Their potential to disrupt genome stability highlights the need to understand how homologous recombination processes are coordinated. The Saccharomyces cerevisiae Rad1–Rad10 endonuclease performs an essential role in recombination between repeated sequences, by processing 3′ single‐stranded intermediates formed during single‐strand annealing and gene conversion events. Several recent studies have focused on factors involved in Rad1–Rad10‐dependent removal of 3′ nonhomologous tails during homologous recombination, including Msh2–Msh3, Slx4, and (...) the newly identified Saw1 protein. Together, this new work provides a model for how Rad1–Rad10‐dependent end processing is coordinated: Msh2–Msh3 stabilizes and prepares double‐strand/single‐strand junctions for Rad1–Rad10 cleavage, Saw1 recruits Rad1–Rad10 to 3′ tails, and Slx4 mediates crosstalk between the DNA damage checkpoint machinery and Rad1–Rad10.

GRW models of the physical world are criticized in the literature for involving wave function "tails" that allegedly create fatal interpretive problems and even compromise standard arithmetic. I find such objections both unfair and misguided. But not all is well with the GRW approach. One complaint I articulate in this paper does not have to do with tails as such but with the specific way in which past physical structures linger forever in the total GRW wave function. By pushing the (...) total proposal towards either the "Many Worlds" approach or the Bohmian approach, this feature diminishes extant GRW claims to preferability. I suggest, however, that the problem here is just an artifact of the particular and ultimately optional genre of collapse mechanism chosen by GRW. (shrink)

Today, the lipid bilayer structure is nearly ubiquitous, taken for granted in even the most rudimentary introductions to cell biology. Yet the image of the lipid bilayer, built out of lipids with heads and tails, went from having obscure origins deep in colloid chemical theory in 1924 to being “obvious to any competent physical chemist” by 1935. This chapter examines how this schematic, strictly heuristic explanation of the idea of molecular orientation was developed within colloid physical chemistry, and how the (...) image was transformed into a reflection of the reality and agency of lipid molecules in the biological microworld. Whereas in physical and colloid chemistry these images considered secondary to instrumental measurement and mathematical modeling of surface phenomena, in biology the manipulable image of the lipid on paper became an essential tool for the molecularization of the cell.

This article focuses on the occasional individuals of many species that live longer than is usual for their populations – here called longevity outliers. They appear to be exceptions to the usual patterns of mortality rates that increase with age. There is no model of survivorship that accommodates all of these individuals. They are less vulnerable to the usual causes of death than most in their populations. There are hints of genetically based mechanisms in the form of life‐prolonging genes in (...) invertebrates and genetic resistance to fatal diseases in higher organisms. The reasons why longevity outliers ultimately die are not known. Based on well‐established trends, I predict that there will be many more humans reaching very old ages in the next century. (shrink)

ABSTRACT The erudite James Burnet, Lord Monboddo (1714–1799), member of the Select Society and judge of the Court of Session in Edinburgh, wrote many pages about the existence of ‘men with tails’ and orang-utans’ humanity. For this reason, he has been labelled as ‘credulous’, ‘bizarre’ and ‘eccentric’ both by his contemporaries and by modern scholars. In this paper, I shall try to take his argument seriously and to show that throughout his work Monboddo searched for evidence. If his belief in (...) mermaids, giants, blemmyes, daemons and oracles was far from reflecting the general attitude of the age of Enlightenment and empiricism, Monboddo contributed to place the ‘science of man’ at the centre of the map of knowledge, where Nicholas Phillipson had also located it. He did this by emphasising the variety and historicity of humankind and stressing how mind and body changed over time and space. This article is also an attempt to connect Monboddo’s erudite production with his position as a lawyer and a judge. I shall argue that Monboddo founded his ‘science of man’ on an epistemology of legal evidence, employing the same inquisitive approach that he practiced at the bar and in the court. (shrink)

Even the most sympathetic readers of Kant's moral philosophy usually disagree with him about some aspect of his theory, or some particular moral judgement. His unqualified condemnation of lying in the essay ‘On a supposed right to lie from philanthropy’ is a classical case in question, as is his strong endorsement of retributive justice and the death penalty. A third prominent source of discontent are Kant's repeated verdicts on the moral status of non-human animals, or rather the lack thereof. For, (...) despite the fact that his practical recommendations in this field are sensible and even progressive, he repeatedly insists that there are no direct duties to animals, that the well-being of animals is morally indifferent, in particular that we ought to treat animals decently solely for the sake of humanity. As a result, the foundations of his advice seem morally inadequate, even offensive. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Three Ovidian Tails PAUL BAROLSKY Kneeling at the edge of a pond in push-up position, a beautiful nude boy crowned with flowers gazes down at the water in which he beholds his reflection. In love, he is enthralled. Thus, the image of Narcissus rendered by the Florentine painter Alessandro Allori in a work that has been largely overlooked until recently. Datable to the second half of the sixteenth century, (...) it now hangs in the Turkish Embassy in Washington, DC. In the distant background of the picture we behold Echo, who extends an arm upward seemingly in a gesture of despair, since she is rejected by Narcissus. She stands before a mass of rock, her left leg beginning to turn to stone, the very stone into which she vanishes as only her voice remains when she echoes her beloved. The painting abounds in Alessandro Allori, Narcissus.

There are other notable details such as the crab on a rock in the foreground, or the clusters of pendulous, ripe grapes, fruit of Bacchus, to whom androgynous Narcissus is likened in Ovid’s Metamorphoses. Allori also employs poetic simile in his picture, since the fingers of the youth’s left hand rhyme with the finger-like roots that emerge from the water. These roots are magnified in turn by their reflected image on the water’s surface. 136 three ovidian tails Abraham Janssens, Nymph and Pan Among the Reeds. AKG / Museen Böttcherstra ße. The apex of the picture, we might say, is baby Cupid who, hovering above, aims his dart at Narcissus and thus arouses the boy’s desire. The shape of Cupid’s bow echoes that of Narcissus ’s prominent buttocks which are framed by the attractive, bright golden drapery fluttering prominently around the youth’s posterior. One might well say that Allori features the buttocks of Narcissus’s body most provocatively in a kind of butt which recalls that of Cupid in the famous Venus, Cupid, Folly, and Time painted by the artist’s teacher, Bronzino. What Allori pictures is not exactly what Ovid writes. It is, however, how Allori imagines the Narcissus of Ovid’s tale. Allori is not alone among Ovidian artists in focusing on the backside of the human body. The posterior is especially prominent in another mythological picture, this one from the early seventeenth century, executed by a disciple of Rubens, Abraham Janssens. This work has found its way to Bremen, where it is now housed in the Ludwig Roselius Museum. It illustrates Pan’s pursuit of Syrinx, who is metamorphosed into reeds in a story told by Mercury in order to put Argus asleep. Ovid is Janssens’s point of departure. The artist depicts the moment when a muscular Pan with a ruddy, almost leathery face embraces Syrinx in her new form as a bunch of reeds. Janssens departs from Ovid with a most novel invention. He depicts a woman, seen from behind, who dominates the composition. With sharp contrasts of lights and darks, vestiges of Caravaggio, the painter emphasizes the female’s imposingly broad backside, which is framed by a billowing, bright, attention-grabbing red drapery that she seems to hold across the front of her body. Could it be that Janssens here alludes to the backside of Syrinx as Pan would have seen it when he chased her? It would seem that we are given not only a view of Pan embracing reeds, we are simultaneously given a Pan’s-eye view of Syrinx’s prominent and provocative backside before her metamorphosis. I wish to consider one final example of the derrière in Ovidian art, this one prominent in a picture painted well Paul Barolsky 137 over a hundred years after Janssens worked: Louis-JeanFran çois Lagrenée’s Abduction of Deianira by the Centaur Nessus, a work which is now in the Louvre.

In this paper, I argue for the modest claim that people's apparent indifference to animal pain may not be predicated upon speciesism. I defend that claim by developing an analogy between current attitudes toward at least some non‐human animal pain — that which pigs endure while having their tails ‘docked’— and our culture's indifference to the pain that male human infants experience while being circumcised. And I conclude that to convince more of their philosophical and social critics, ‘animal liberationists’ need (...) to spend more time analyzing the pain that non‐human animals experience and defending its moral significance, rather than assuming that such pain is significant and then simply arguing that unnecessary forms of it exist.

Hawai'i played a significant role in (...) providing a more culturally porous milieu for the veterans to meet, away from the mainstream tensions in each of their respective nations. (shrink)

Ex ante predicted outcomes should be interpreted as counterfactuals (potential histories), with errors as the spread between outcomes. But error rates have error rates. We reapply measurements of uncertainty about the estimation errors of the estimation errors of an estimation treated as branching counterfactuals. Such recursions of epistemic uncertainty have markedly different distributial properties from conventional sampling error, and lead to fatter tails in the projections than in past realizations. Counterfactuals of error rates always lead to fat tails, regardless of (...) the probability distribution used. A mere .01% branching error rate about the STD (itself an error rate), and .01% branching error rate about that error rate, etc. (recursing all the way) results in explosive (and infinite) moments higher than 1. Missing any degree of regress leads to the underestimation of small probabilities and concave payoffs (a standard example of which is Fukushima). The paper states the conditions under which higher order rates of uncertainty (expressed in spreads of counterfactuals) alters the shapes the of final distribution and shows which a priori beliefs about conterfactuals are needed to accept the reliability of conventional probabilistic methods (thin tails or mildly fat tails).

This paper argues that if 'reforms' of education designed to raise standards leave unquestioned the notion of fixed differential ability, then they are likely to be self-defeating.

Current phylogenies show that paired fins and limbs are unique to jawed vertebrates and their immediate ancestry. Such fins evolved first as a single pair extending from an anterior location, and later stabilized as two pairs at pectoral and pelvic levels. Fin number, identity, and position are therefore key issues in vertebrate developmental evolution. Localization of the AP levels at which developmental signals initiate outgrowth from the body wall may be determined by Hox gene expression patterns along the lateral plate (...) mesoderm. This regionalization appears to be regulated independently of that in the paraxial mesoderm and axial skeleton. When combined with current hypotheses of Hox gene phylogenetic and functional diversity, these data suggest a new model of fin/limb developmental evolution. This coordinates body wall regions of outgrowth with primitive boundaries established in the gut, as well as the fundamental nonequivalence of pectoral and pelvic structures.

Contemporary Indian identification with Hindu traditions (whether more narrowly or broadly conceived) among champions of animal protection often invokes the well-known concept of ahiṁṣā—nonviolence, as the moral basis for the position against violence toward non-human animals. To foster a more informed comprehension of this notion, this paper sets out the complex character of religious practice as presented in the Hindu scripture Bhagavad-gītā, to explore how its tenets might meaningfully apply to the practice of animal experimentation.

One of the classic papers of Australian feminist philosophy is G. Lloyd's "The Man of Reason" (Lloyd, 1979). The main concern of this paper is the alleged maleness of the Man of Reason, i.e., the thesis that our philosophical tradition in some deep way associates the concepts rational and male. Lloyd claims that her main goal is to bring this "undoubted" thesis "into clearer focus" (p.18), and indeed she makes no strenuous effort to demonstrate that the to-be-clarified thesis is actually (...) true. There are however a few places where she advances material she seems to be taking as some kind of evidence that the Man of Reason is male. One is on the second page, where she quotes from Augustine: And finally we see man, made in your image and likeness, ruling over all the irrational animals for the very reason that he was made in your image and resembles you, that is because he has the power of reason and understanding. And just as in man's soul there are two forces; on which is dominant because it deliberates and one which obeys because it is subject to such guidance, in the same way in the physical sense, woman has been made for man. In her mind and her rational intelligence she has a nature the equal of man's, but in sex she is physically subject to him in the same way as our natural impulses need to be subjected to the reasoning power of the mind, in order that the actions to which they lead may be inspired by the principles of good conduct. Now an interesting feature of this passage is that it appears to directly contradict the thesis of the maleness of the Man of Reason. Far from saying that rationality is a male prerogative, Augustine claims that "in her mind and her rational intelligence she has a nature the equal of man's" (my emphasis). Certainly Augustine claims that in sex woman is subject to man, and he also claims that there is an analogy or parallel between the dominance of man over woman in sex and the dominance of the rational part of the mind over the natural impulses..
