Three‐ to 4‐month‐old infants show asymmetric exclusivity in the acquisition of cat and dog perceptual categories. The cat perceptual category excludes dog exemplars, but the dog perceptual category does not exclude cat exemplars. We describe a connectionist autoencoder model of perceptual categorization that shows the same asymmetries as infants. The model predicts the presence of asymmetric retroactive interference when infants acquire cat and dog categories sequentially. A subsequent experiment conducted with 3‐ to 4‐month‐olds verifies the predicted pattern (...) of looking time behaviors. We argue that bottom‐up, associative learning systems with distributed representations are appropriate for modeling the operation of short‐term visual memory in early perceptual category learning.

Associative learning is an essential feature of human cognition, accounting for the influence of priming and interference effects on memory recall. Here, we extend our account of associative learning that learns asymmetric item-to-item associations over time via experience by including link maturation to balance associations between longer-term stability while still accounting for short-term variability. This account, combined with an existing account of activation strengthening and decay, predicts both human response times and error rates for the fan effect for (...) both target and foil stimuli.

For several decades, theorists interested in Kant’s discussion of welfare have puzzled over Kant’s position on the issue of the redistribution of goods in society. They have done this both in order to clarify his position and as a source of inspiration for current conceptual problems faced by contemporary political philosophers who attempt to reconcile the ideal of equal freedom with the asymmetric interference necessary for redistribution and social provision. In this paper, I start with Kant’s brief discussion (...) of welfare in Rechtslehre and I identify four claims that Kant clearly asserts as characteristic for his view. I then outline five main interpretative directions in the literature, I evaluate and rank them. The most accurate view of Kant’s justification of welfare, which I call the “genuinely Kantian” position is, however, unable to explain the nature of the duty of welfare that it asserts. By going back to Kant’s text, I suggest one solution. This solution, together with some further questions, can be seen as initiating a new interpretative direction in the literature. (shrink)

We investigate a system of two species exploiting a common resource. We consider both abiotic (i.e. with a constant resource supply rate) and biotic (i.e. with resource reproduction and self-limitation) resources. We are interested in the asymmetric competition where a given consumer is the locally superior resource exploiter (LSE) and the other is the locally inferior resource exploiter (LIE). They also interact directly via interference competition in the sense that LIE individuals can use two opposite strategies to compete (...) with LSE individuals: we assume, in the first case, that LIE uses an avoiding strategy, i.e. LIE individuals go to a non-competition patch to avoids competition with LSE individuals, and in the second one, LIE uses an aggressive strategy, i.e. being very aggressive so that LSE individuals have to go to a non-competition patch. We further assume that there is no resource in the non-competition patch so that individuals have to come back to the competition patch for their maintenance, and the migration process acts on a fast time scale in comparison with demography and competition processes. The models show that being aggressive is efficient for LIE’s survival and even provoke global extinction of the LSE and this result does not depend on the nature of resource. (shrink)

Similar to visual perception, auditory perception also has a clearly described “pop-out” effect, where an element with some extra feature is easier to detect among elements without an extra feature. This phenomenon is better known as auditory perceptual asymmetry. We investigated such asymmetry between shorter or longer duration, and level or falling of pitch of linguistic stimuli that carry a meaning in one language (Estonian), but not in another (Russian). For the mismatch negativity (MMN) experiment, we created four different types (...) of stimuli by modifying the duration of the first vowel [ɑ] (170, 290 ms) and pitch contour (level vs. falling pitch) of the stimuli words (‘SATA,’ ‘SAKI’). The stimuli were synthesized from Estonian words (‘SATA,’ ‘SAKI’) and follow the Estonian language three-way quantity system, which incorporates tonal features (falling pitch contour) together with temporal patterns. This made the meaning of the word dependent on the combination of both features and allows us to compare the relative contribution of duration and pitch contour in discrimination of language stimuli in the brain via MMN generation. The participants of the experiment were 12 Russian native speakers with little or no experience in Estonian and living in Estonia short-term, and 12 Estonian native speakers (age 18–27 years). We found that participants’ perception of the linguistic stimuli differed not only according to the physical features but also according to their native language, confirming that the meaning of the word interferes with the early automatic processing of phonological features. The GAMM and ANOVA analysis of the reversed design results showed that the deviant with longer duration among shorter standards elicited a MMN response with greater amplitude than the short deviant among long standards, while changes in pitch contour (falling vs. level pitch) produced neither strong MMN nor asymmetry. Thus, we demonstrate the effect of language background on asymmetric perception of linguistic stimuli that aligns with those of previous studies (Jaramillo et al., 2000), and contributes to the growing body of knowledge supporting auditory perceptual asymmetry.

State legitimacy is often said to have two aspects: an internal and an external one. Internally, a legitimate state has the right to rule over its subjects. Externally, it has a right that outsiders not interfere with its domestic governance. But what is the relation between these two aspects? In this paper, I defend a conception of legitimacy according to which these two aspects are related in an importantly asymmetrical manner. In particular, a legitimate state’s external right to rule affords (...) it protections that include and go beyond what its internal right to rule enables it to do. This asymmetrical view, I argue, is preferable to its two main rivals: the view that a state’s internal and external legitimacy are separate issues, and the view that internal and external legitimacy are mirroring.

In the last seven years, close to twenty thousand people have died trying to reach Europe by crossing the Mediterranean Sea. Rescue missions by private actors and NGOs have increased because both national measures and measures by the EU’s border control agency, Frontex, are often deemed insufficient. However, such independent rescue missions face increasing persecution from national governments, Italy being one example. This raises the question of how potential migrants and dissenting citizens should act towards the EU border regime. In (...) contrast to the literature, which mainly addresses migration on the basis of justice requirements, this article focuses on the legitimate authority of the EU’s border regime. Focusing on the legitimacy criteria for states’ claims to regulate migration opens a fruitful normative perspective, given the pervasive disagreement over the content of justice in migration. What reasons for compliance and non-interference does legitimacy supply for potential immigrants and dissenting citizens? And what legitimacy standard may be appropriate for the power that individual states claim over potential immigrants? We argue that, even assuming a minimal legitimacy standard for the state-migrant relationship, the structure of the EU’s border regime exhibits unique features, which cause it to stand in tension with such a standard. By coordinating its Member States’ border regimes, especially through Frontex, the EU claims and exercises power over potential immigrants. However, the asymmetrical delegation of state powers to the EU means that the power involved in regulating European borders is, in core respects, unaccountable. This unaccountability, we argue, is significant for the legitimacy of the EU’s border regime. This article sheds new light on the morality of unauthorised rescue missions by assessing the permissibility of resistance to the EU’s border regime. (shrink)

This dissertation argues for an interpretation of liberty in terms of non-domination rather than non-interference, that non-domination can work as an independent criterion of political legitimacy, and that non-domination includes an approximation of equality in socioeconomic goods. In the first part, four theories of liberty and power – those of Kant, Locke, J. S. Mill and H. Taylor, and Wollstonecraft – are analyzed. It is concluded that Locke and Wollstonecraft, and Mill and Taylor partly, but not Kant, offer non-domination (...) oriented conceptions of liberty. It is also tentatively argued that this has repercussions for their ideas on sex equality. In the second part a systematic discussion is offered in support of the three aims of the disseration. Non-domination is a socially radical, but not republican value. A distinction is made between liberty and freedom; “liberty” is normative and “freedom” empirical. One’s freedom can be restrained without one’s liberty being infringed, which typically would be the case where there is interference but no relation of dominance. Non-domination addresses asymmetrical relations of power and is inherently egalitarian. One’s liberty is infringed to the extent an agent has the power to interfere with one, whether interference actually takes place or not. Non-domination works as a twofold criterion of legitimacy: A legitimate state furthers non-domination between citizens under the circumstances of certain constitutional restrictions. The absence of vulnerability to the interference of others that non-domination requires, has to be institutionally secured. One aspect of dominance is the socioeconomic relation between people, and an approximation of socioeconomic equality will therefore be a political concern. (shrink)

The author outlines a conception of toleration as recognition of differences which she argues to be more adequate than current liberal views in order to face issues arising from contemporary pluralism. The liberal conception of toleration as freedom from government's interference in certain areas is appropriate if pluralism is conceived of as a plurality of conflicting conceptions of the good. By contrast, if pluralism is understood as the plurality of groups and cultures, asymmetrically situated in democratic society, then the (...) issues underlying toleration are seen as the contested claim of minorities for asserting their different identity in the public space. Public toleration of differences is thus viewed as a symbolic public gesture of inclusion of the different identities and their bearers into democratic citizenship on an equal footing as members of minority groups. The argument supporting public toleration is so founded on reason of justice. (shrink)

This essay introduces this special issue on virtue ethics in relation to military AI. It describes the current situation of military AI ethics as following that of AI ethics in general, caught between consequentialism and deontology. Virtue ethics serves as an alternative that can address some of the weaknesses of these dominant forms of ethics. The essay describes how the articles in the issue exemplify the value of virtue-related approaches for these questions, before ending with thoughts for further research.

Asymmetric cell division generates cell diversity and contributes to cellular aging and rejuvenation. Here, we review the molecular mechanisms enabling budding yeast to recognize spindle pole bodies (SPB, centrosome equivalent) based on their age, and guide their non‐random mitotic segregation: SPB inheritance requires the distinction of old from new SPBs and is regulated by the SPB‐inheritance network (SPIN) and the mitotic exit network (MEN). The SPIN marks the pre‐existing SPB as old and the MEN recognizes these marks translating them (...) into spindle orientation. We next revisit other molecules and structures that partition depending on their age rather than their abundance at mitosis as, for example, DNA, centrosomes, mitochondria, and histones in yeast and other systems. The recurrence of this differential behavior suggests a functional significance for numerous cell types, which we then discuss. We conclude that non‐random segregation may facilitate asymmetric cell fate determination and thereby indirectly aging and rejuvenation. (shrink)

The segregation of damaged components at cell division determines the survival and aging of cells. In cells that divide asymmetrically, such as Saccharomyces cerevisiae, aggregated proteins are retained by the mother cell. Yet, where and how aggregation occurs is not known. Recent work by Zhou and collaborators shows that the birth of protein aggregates, under specific stress conditions, requires active translation, and occurs mainly at the endoplasmic reticulum. Later, aggregates move to the mitochondrial surface through fis1‐dependent association. During replicative aging, (...) aggregate association with the mother‐cell mitochondria contributes to the asymmetric segregation of aggregates, because mitochondria in the daughter cell do not carry aggregates. With increasing age of mother cells, aggregates lose their connection to the mitochondria, and segregation is less asymmetric. Relating these findings to other mechanisms of aggregate segregation in different organisms, we postulate that fusion between aggregates and their tethering to organelles such as the vacuole, nucleus, ER, or mitochondria are common principles that establish asymmetric segregation during stress resistance and aging.

This article addresses the question whether companies benefit from their commitment to corporate social responsibility. The authors argue that firms which score high on CSR activities build investor confidence and find evidence that they benefit from lower information asymmetry. The authors measure information asymmetry by insider trading, which is defined as the trading of a company’s shares by corporate insiders who have an information advantage with the aim to reap gains or avoid losses. Using a sample of U.S. firms listed (...) in the MSCI World Index during the period 2004 to 2013 and the firm- and industry-level CSR rating from Global Engagement Service, the authors show that insider transactions in firms with a high score on CSR activities lead to lower abnormal returns. This investigation extends current literature on the business case for CSR by explaining the influence of CSR activities on asymmetric information. (shrink)

Sex reversal, a mismatch between phenotypic and genetic sex, can be induced by chemical and thermal insults in ectotherms. Therefore, climate change and environmental pollution may increase sex‐reversal frequency in wild populations, with wide‐ranging implications for sex ratios, population dynamics, and the evolution of sex determination. We propose that reconsidering the half‐century old theory “Witschi's rule” should facilitate understanding the differences between species in sex‐reversal propensity and thereby predicting their vulnerability to anthropogenic environmental change. The idea is that sex reversal (...) should be asymmetrical: more likely to occur in the homogametic sex, assuming that sex‐reversed heterogametic individuals would produce new genotypes with reduced fitness. A review of the existing evidence shows that while sex reversal can be induced in both homogametic and heterogametic individuals, the latter seem to require stronger stimuli in several cases. We provide guidelines for future studies on sex reversal to facilitate data comparability and reliability. (shrink)

Fodor’s asymmetric-dependence theory of content is probably the best known and most developed causal or informational theory of mental content. Many writers have attempted to provide counterexamples to Fodor’s theory. In this paper, I offer a more fundamental critique. I begin by attacking Fodor’s view of the dialectical situation. Fodor’s theory is cast in terms of laws covering the occurrence of an individual thinker’s mental symbols. I show that, contrary to Fodor’s view, we cannot restrict consideration to hypothetical cases (...) in which his conditions for content are satisfied, but must consider whether the relevant laws exhibit the specified asymmetric-dependence relations in actual cases. My central argument is that the laws that the theory requires do not in fact exhibit the appropriate asymmetric-dependence relations. I show that, in general, part of the mechanism for the crucial, supposedly content-determining law for a mental symbol is not shared by the mechanisms for the other laws covering the occurrence of the same mental symbol. As a result, the former law can be eliminated (by eliminating the non-overlapping part of the mechanism) without eliminating the latter laws. The latter laws do not asymmetrically depend on the former law. (shrink)

In doing so I critique Moravscik by drawing a distinction between ontological and conceptual dependencies.

Instead of investigating the interference between two stationary, rectilinear wave functions in a trajectory representation by examining the trajectories of the two rectilinear wave functions individually, we examine a dichromatic wave function that is synthesized from the two interfering wave functions. The physics of interference is contained in the reduced action for the dichromatic wave function. As this reduced action is a generator of the motion for the dichromatic wave function, it determines the dichromatic wave function’s trajectory. The (...) quantum effective mass renders insight into the behavior of the trajectory. The trajectory in turn renders insight into quantum nonlocality. (shrink)

Desire-satisfaction theories of welfare must answer the timing question: when do you benefit from the satisfaction of one of your desires? There are three existing views about this: the Time of Desire view, on which you benefit at just those times when you have the desire; the Time of Object view, on which you benefit just when the object of your desire obtains; and Concurrentism, on which you benefit just when you have the desire and its object obtains. This paper (...) introduces a new view, Asymmetrism, on which you sometimes benefit at the time of desire and sometimes benefit at the time of object. On this view, if the time at which you have a desire is later than the time at which its object obtains, then you benefit at the time of the desire. On the other hand, if the time of object is later than the time of desire, then you benefit at the time of object. Three arguments are given for the conclusion that Asymmetrism is superior to the Time of Desire and Time of Object views. It is argued that Asymmetrism and Concurrentism are the most credible answers to the timing question. (shrink)

Guest editors' introduction to the issue containing essays originally presented at the 2022 Philosophy of Education Society conference examining Mary Louise Pratt's notion of "contact zones." This issue includes discussions that highlight the “highly asymmetrical relations of power, such as colonialism, slavery, or their aftermaths” of contact zones in which we teach and learn. Pratt draws attention towards asymmetry to emphasize the social differences and fluidity of relations that characterize communities (including classrooms), over and against ideas of community that are (...) homogeneous or horizontal. In this issue, we invite readers to consider how these asymmetries play out beyond the classroom itself, through institutional contact as well as through political systems that shape our relationships.

in Undetermined On an influential interpretation, the agent's degrees of belief asr identified with her betting rates. However, being placed in a betting situation can itself change one’s degree of belief in the proposition in question. The problem as such isn’t new. Ramsey, for example, was right on to this idea when he wrote: "… the proposal of a bet may inevitably alter [one’s] state of opinion; just as we could not always measure electric intensity by actually introducing a charge (...) and seeing what force it was subject to, because the introduction of the charge would change the distribution to be measured." This ‘interference problem’ for the betting interpretation can best be put in the following way: The bets we are disposed to accept do not manifest our current unconditional degrees of belief in various propositions. Whether a bet on A would be accepted or not does not depend on the agent’s degree of belief in A but rather on the degree of belief she would have if she were confronted with this bet proposal, or – more generally – the degree of belief she would have if she were in a position to bet on A. Assuming the conditionalization model for belief change, this means that whether the agent would be willing to bet depends on her current conditional beliefs concerning A on the hypothetical supposition that she has an opportunity to make this bet. Furthermore, her disposition to bet also depends on the expected effects the act of betting would have on the truth of the proposition to be betted on. Both these phenomena imply that finding oneself in a betting situation might alter one’s expectations in important ways. Consequently, the identification of degrees of belief with betting rates is a mistake. We show that this problem comes up in several different versions, or – equivalently – that different kinds of arguments against the betting interpretation stem from the same source. (shrink)

In this paper, I argue on empirical grounds that (VL-initial) Asymmetric Coordination in German cannot be reduced to a syntactic structure of the form [if S1, then S2], but rather needs to be analyzed as some kind of adjunction to the if-clause, i.e., along the lines of [[if S1] and S2]. This conclusion gives rise to an apparent mismatch between syntactic structure (narrow scope of if) and semantic interpretation (wide scope of if). To resolve this paradoxical situation, I propose (...) a compositional semantics for conditionals that is based on the idea that (indexed) if is to be construed as some kind of anaphor (variable) that ranges over objects of type modal base picking up a modal background in the actual context. Even though this analysis assigns a non-vacuous semantics to the complementizer if, it is still compatible with the syntax of Asymmetric Coordination in German, and, in contrast to alternative accounts, avoids the generation of non-existent distributive readings.

We conducted two eye-tracking experiments investigating the processing of the Mandarin reflexive ziji in order to tease apart structurally constrained accounts from standard cue-based accounts of memory retrieval. In both experiments, we tested whether structurally inaccessible distractors that fulfill the animacy requirement of ziji influence processing times at the reflexive. In Experiment 1, we manipulated animacy of the antecedent and a structurally inaccessible distractor intervening between the antecedent and the reflexive. In conditions where the accessible antecedent mismatched the animacy cue, (...) we found inhibitory interference whereas in antecedent-match conditions, no effect of the distractor was observed. In Experiment 2, we tested only antecedent-match configurations and manipulated locality of the reflexive-antecedent binding (Mandarin allows non-local binding). Participants were asked to hold three distractors (animate vs. inanimate nouns) in memory while reading the target sentence. We found slower reading times when animate distractors were held in memory (inhibitory interference). Moreover, we replicated the locality effect reported in previous studies. These results are incompatible with structure-based accounts. However, the cue-based ACT-R model of Lewis and Vasishth ( 2005 ) cannot explain the observed pattern either. We therefore extend the original ACT-R model and show how this model not only explains the data presented in this article, but is also able to account for previously unexplained patterns in the literature on reflexive processing.

This thesis is guided by the following question: what, if anything, makes a life meaningful? My answer to this question is asymmetric welfarism about meaning in life. According to asymmetric welfarism, the meaning of a life depends upon two factors. First, a life is conferred meaning insofar as it promotes or protects the well-being of other welfare subjects. Second, a life is made meaningless insofar as it decreases or minimises the well-being of other welfare subjects. The meaning of (...) a life is determined by the net balance between these two factors; the more the good outweighs the bad, the more meaningful a life that is. I argue that asymmetric welfarism is the most plausible theory about meaning in life. To do this, I show how such a view captures a variety of intuitions about meaning in life while defending it from objections. This is the business of chapters 1, 2, and 3. Specifically, chapter 1 lays the groundwork, chapter 2 advances the case in favour of asymmetric welfarism, while chapter 3 defends asymmetric welfarism from objections. But some objections cannot be so easily overturned by a mere argument. Such objections do not just count against asymmetric welfarism, but also support competing theories. In order to overcome both, I show how such objections, and the theories they motivate, are best understood as tracking a different, but related, evaluative dimension a life can have. This is the business of chapters 4, 5, and 6. Specifically, chapter 4 argues that subjective theories are best understood as being about fulfilment, chapter 5 argues that purpose theories are best understood as being about purpose, and chapter 6 argues that differing views about the role of morality confuse morality and significance with meaning. These other evaluative dimensions which stand alongside meaning in life are fulfilment, purpose, significance, morality, and prudential value. (shrink)

I discuss the interpretation of a recent experiment showing quantum interference in time. It is pointed out that the standard nonrelativistic quantum theory does not have the property of coherence in time, and hence cannot account for the results found.

Some theoretical structures which consider the time as an observable, and thus could, in principle, have the required coherence in time, are discussed briefly, and the application of (...) Floquet theory and the manifestly covariant quantum theory of Stueckelberg are treated in some detail. In particular, the latter is shown to account for the results in a simple and consistent way.

Two enzymes involved in the synthesis of pyrimidine and purine nucleotides, CTP synthase (CTPS) and IMP dehydrogenase (IMPDH), can assemble into a single or very few large filaments called rods and rings (RR) or cytoophidia. Most recently, asymmetric cytoplasmic distribution of organelles during cell division has been described as a decisive event in hematopoietic stem cell fate. We propose that cytoophidia, which could be considered as membrane‐less organelles, may also be distributed asymmetrically during mammalian cell division as previously described (...) for Schizosaccharomyces pombe. Furthermore, because each type of nucleotide intervenes in distinct processes (e.g., membrane synthesis, glycosylation, and G protein‐signaling), alterations in the rate of synthesis of specific nucleotide types could influence cell differentiation in multiple ways. Therefore, we hypothesize that whether a daughter cell inherits or not CTPS or IMPDH filaments determines its fate and that this asymmetric inheritance, together with the dynamic nature of these structures enables plasticity in a cell population.

In this essay, I defend an account of right action that I shall call “asymmetrical virtue particularism.” An action, on this account, is right just insofar as it is overall virtuous. But the virtuousness of an action in any particular respect, X, is deontically variant; it can fail to be right-making, either because it is deontically irrelevant or because it is wrong-making. Finally, the account is asymmetrical insofar as the viciousness of actions is not deontically variant; if any action is (...) vicious in some respect Y, then Y is always a wrong-making feature of any action whatever that has Y.

We examined interference effects of emotionally associated background colours during fast valence categorisations of negative, neutral and positive expressions. According to implicitly learned colour–emotion associations, facial expressions were presented with colours that either matched the valence of these expressions or not. Experiment 1 included infrequent non-matching trials and Experiment 2 a balanced ratio of matching and non-matching trials. Besides general modulatory effects of contextual features on the processing of facial expressions, we found differential effects depending on the valance of (...) target facial expressions. Whereas performance accuracy was mainly affected for neutral expressions, performance speed was specifically modulated by emotional expressions indicating some susceptibility of emotional expressions to contextual features. Experiment 3 used two further colour–emotion combinations, but revealed only marginal interference effects most likely due to missing colour–emotion associations. The results are discussed with respect to inherent processing demands of emotional and neutral expressions and their susceptibility to contextual interference. (shrink)

A striking feature of human female sexual reproduction is the high level of gametes that exhibit an aberrant number of chromosomes (aneuploidy). A high baseline observed in women of prime reproductive age is followed by a dramatic increase in older women. Proper chromosome segregation requires one or more DNA crossovers (COs) between homologous maternal and paternal chromosomes, in combination with cohesion between sister chromatid arms. In human females, CO designations occur normally, according to the dictates of CO interference, giving (...) early CO-fated intermediates. However, ≈25% of these intermediates fail to mature to final CO products. This effect explains the high baseline of aneuploidy and is predicted to synergize with age-dependent cohesion loss to explain the maternal age effect. Here, modern advances in the understanding of crossing over and CO interference are reviewed, the implications of human female CO maturation inefficiency are further discussed, and areas of interest for future studies are suggested.

Asymmetry theories about free will and moral responsibility are a recent development in the long history of the free will debate. Kant commentators have not yet explored the possibility of an asymmetrical reconstruction of Kant's theory of freedom, and that is my goal here. By "free will", I mean the sort of control we would need to be morally responsible for our actions. Kant's term for it is "transcendental freedom", and he refers to the attribution of moral responsibility as "imputation". (...) By "Kant's theory of freedom", I mean not only his theory of transcendental freedom and imputation, but also the various ways in which he draws on these ideas in his moral theory. (shrink)

Analogies must be symmetric. If a is like b, then b is like a. So if a has property R, and if R is within the scope of the analogy, then b (probably) has R.

I defend the importance of this neglected – even when explicitly mentioned – (...) feature in understanding analogical arguments. (shrink)

The relationship between Fisher's fundamental theorem of natural selection and the ecological environment of density regulation is examined. Using a linear model, it is shown that the theorem holds when density regulation is caused by exploitative competition and that the theorem fails with interference competition. In the latter case the theorem holds only at the limit of zero population density and/or at the limit where the competitively superior individuals cannot monopolise the resource. The results are discussed in relation to (...) population dynamics and life history evolution, where evidence suggests that the level of interference competition in natural populations is so high that the fundamental theorem does not apply.
