This study investigates the ability of individuals with psychopathy to perform passive avoidance learning and whether this ability is modulated by level of reinforcement/punishment. Nineteen psychopathic and 21 comparison individuals, as defined by the Hare Psychopathy Checklist Revised (Hare, 1991), were given a passive avoidance task with a graded reinforcement schedule. Response to each rewarding number gained a point reward specific to that number (i.e., 1, 700, 1400 or 2000 points). Response to each punishing number lost a point punishment specific (...) to that number (i.e., the loss of 1, 700, 1400 or 2000 points). In line with predictions, individuals with psychopathy made more passive avoidance errors than the comparison individuals. In addition, while the performance of both groups was modulated by level of reward, only the performance of the comparison population was modulated by level of punishment. The results are interpreted with reference to a computational account of the emotional learning impairment in individuals with psychopathy. (shrink)

Jus post Bellum is, like Jus ad Bellum and Jus in Bello, a part of just war theory. Jus post Bellum is distinguished from the other parts of just war theory by being primarily concerned with the principles necessary for securing a just and lasting peace after the end of a war. Traditionally, jus post bellum has focused primarily on three goals: [1] compensating those who have been the victims of unjust aggression, while respecting the rights of the aggressors, [2] (...) punishing and rehabilitating those guilty of war crimes and other violations of the principles of Jus ad Bellum and Jus in Bello and [3] developing measures that will prevent future war and violence (Orend 2000 and May 2012). In this chapter, I outline an account of political forgiveness and explain the role that political forgiveness can have in promoting the goals of jus post bellum. My conception of political forgiveness requires some unpacking. Let me begin with individual forgiveness, which I understand along familiar Butlerian lines as the renunciation of resentment (Butler, Sermon IX in McNaughton 2017: 75-83), though with a bit of a twist. More exactly, ● An individual, I, forgives J for doing F if and only if I renounces all her own warrant for resenting J for doing F. Resentment is a judgment-sensitive attitude, and, therefore, it tends to track judgments concerning its warrant (Scanlon 1998: 20 and Smith 2015). In cases of perfect forgiveness, I’s renunciation causes her to cease feeling resentment toward J for doing F, though, of course, less perfect cases are possible. I reject the idea that there is a sharp discontinuity between individual and political forgiveness, a position argued for by, e.g., Peter Digeser (1998 and 2001). By contrast, I understand political forgiveness as the renunciation of resentment by the relevant political body in question. With greater precision, ● A sovereign political body, P, forgives J for doing F if and only if P renounces all warrant that its citizens have for resenting, as part of their public lives, J for doing F. A little more explanation is in order. Sovereign political bodies, such as national governments, claim degrees of control over the lives of their citizens, in both their public and their private aspects, though the claims with respect to the former tend to be considerably more expansive than the claims with respect to the latter. I assume here that, at least in the case of legitimate governments, these claims of control are often valid. Such governments may reasonably renounce certain grounds for motivating action in the public sphere. For example, governments may renounce all warrant that its citizens have, as part of their public lives, for hating members of marginalized groups. In practice, this means that, while citizens might continue to act in their private lives out of hatred for members of these groups, their appeal to this hatred is seen by the state as irrelevant to matters of law and public policy as well as being wholly out-of-place in public discourse. Political forgiveness toward J for doing F, as I understand it, involves an analogous rejection of resentment, on the part of citizens in their public lives, toward J for doing F. I turn now to the matter of how political forgiveness supports securing a just and lasting peace between former belligerents. With respect to the first goal of jus post bellum, political forgiveness helps to balance compensation for victims and respect for the rights of defeated aggressors by countering the all-too-human tendency to overvalue harms done to oneself and to members of one’s group. As regards the second goal, political forgiveness plays a similar role but also provides a model for rehabilitation by exemplifying among the victorious the behavior to be emulated by the vanquished. Finally, political forgiveness promotes the third goal of jus post bellum by providing a space for nations to meet as moral equals rather than allowing one nation to have the moral high ground over the other. None of this, of course, means that political forgiveness should be unearned or that it should be confused with condonation (Kolnai 1973 and Pettigrove 2004). However, the question of what is required to put oneself in a position to be forgiven as part of jus post bellum is a matter that goes beyond the scope of this chapter. (shrink)

Many researchers and intellectuals warn about extreme risks from artificial intelligence. However, these warnings typically came without systematic arguments in support. This paper provides an argument that AI will lead to the permanent disempowerment of humanity, e.g. human extinction, by 2100. It rests on four substantive premises which it motivates and defends: first, the speed of advances in AI capability, as well as the capability level current systems have already reached, suggest that it is practically possible to build AI systems (...) capable of disempowering humanity by 2100. Second, due to incentives and coordination problems, if it is possible to build such AI, it will be built. Third, since it appears to be a hard technical problem to build AI which is aligned with the goals of its designers, and many actors might build powerful AI, misaligned powerful AI will be built. Fourth, because disempowering humanity is useful for a large range of misaligned goals, such AI will try to disempower humanity. If AI is capable of disempowering humanity and tries to disempower humanity by 2100, then humanity will be disempowered by 2100. This conclusion has immense moral and prudential significance.

This study examined the effects of emotional subject matter and descriptive style in short story excerpts on text (e.g. rich in meaning) and reader response-oriented (e.g. liking) ratings. Forty-eight subjects, including equal numbers of trained and novice male and female students, read two examples of each text twice and either generated or received interpretations between readings in a within-subjects design. In general, intellectual challenge slowed the pace of reading, whereas suspense-based arousal increased it. Emotional subject matter had a more powerful (...) effect than descriptive style on both cognitive (challenging, rich in meaning) and affective (expressive, personally relevant) scales and were read more quickly. Generating interpretations fostered subjective reactions to the Emotional excerpts (images), whereas Descriptive texts were less amenable to subjective responses. Consistent effects were also found for background and gender. As in everyday life, subject matter had a dominant effect in engaging a person's involvement. (shrink)

This paper aims to establish three major theses: (1) Not only declarative sentences, but also interrogatives and imperatives, may be classified as true or as false. (2) Declarative, imperative, and interrogative utterances may also be classified as honest or as dishonest. (3) Whether an utterance is honest or dishonest is logically independent of whether it is true or is false. The establishment of the above theses follows upon the adoption of a principle for identifying what is meant by any sentence, (...) declarative, interrogative, or imperative. The analysis aims to show that meaning is to be attributed to the uttered or written sentence-token, rather to the thereby exhibited sentence-type. Further, the meaning of the sentential token is to be identified with a purpose of the speaker, that the speaker would reveal to the addressee by uttering the sentence. The to be revealed purpose is analysed into two components: an ultimate concern (that the addressee stand in such and such a relation--e.g., of believing, or informing the speaker about, or making it true that) and an ultimate topic of concern (the state of affairs, i.e., proposition, relative to which the speaker would have the addressee stand in the specified relation). Sentential utterances "signify" different purposes by "expressing" different ultimate concerns and "indicating" different ultimate topics of concern. Variations in expressed concern are correlated with variations in sentential form, such as declarative, interrogative and imperative. Variations in indicated topic of concern are correlated with variations in the subject and predicate of the uttered sentence. Thus, for example, utterances of "Johnny will jump in the lake," "Will Johnny jump in the lake?" and "Johnny, go jump in the lake!" all indicate one and the same ultimate topic of concern but express different ultimate concerns with this topic. A sentential utterance is true or false according as its indicated topic of concern is true or false. Hence, declaratives, interrogatives and imperatives may all be classified as true or as false. But honesty or dishonesty is a function (explained in the paper) of the expressed concern, rather than of the topic of concern. Hence, although utterances of all sentential forms are honest or dishonest, their honesty or dishonesty is logically independent of their truth or falsity. (shrink)

Sortal terms, such as table or horse, are count nouns (akin to a basic-level terms). According to some theories, the meaning of sortals provides conditions for telling objects apart (individuating objects, e.g., telling one table from a second) and for identifying objects over time (e.g., determining that a particular horse at one time is the same horse at another). A number of psychologists have proposed that sortal concepts likewise provide psychologically real conditions for individuating and identifying things. However, this paper (...) reports five experiments that cast doubt on these psychological claims. Experiments 1-3 suggest that sortal concepts do not determine when an object ceases to exist and therefore do not decide when the object can no longer be identical to a later one. Experiments 4-5 similarly suggest that sortal concepts do not provide determinate conditions for individuating objects. For example, they do not always decide whether a room contains one table or two. All five experiments feature ordinary objects undergoing ordinary changes. (shrink)

Children with specific language impairment (SLI) show a protracted period of inconsistent use of tense/agreement morphemes. The purpose of this investigation was to determine whether this inconsistent use could be attributed to the children's misinterpretations of particular syntactic structures in the input. In Study 1, preschool-aged children with SLI and typically developing peers heard sentences containing novel verbs preceded by auxiliarywasor sentences in which the novel verb formed part of a nonfinite subject-verb sequence within a larger syntactic structure (e.g.We saw (...) the dog relling). The children were then tested on their use of the novel verbs in contexts that obligated use of auxiliaryis. The children with SLI were less accurate than their peers and more likely to produce the novel verb withoutisif the verb had been heard in a nonfinite subject-verb sequence. In Study 2, children with SLI and typically developing peers were tested on their comprehension of sentences such asThe cow sees the horse eating. The children with SLI were less accurate than their peers and were disproportionately influenced by the nonfinite subject-verb clause at the end of the sentence. We interpret these findings within the framework of construction learning. (shrink)

Background COVID-19 has greatly impacted the health of incarcerated individuals in the US. The goal of this study was to examine perspectives of recently incarcerated individuals on greater restrictions on liberty to mitigate COVID-19 transmission.Methods We conducted semi-structured phone interviews from August through October 2021 with 21 people who had been incarcerated in Bureau of Prisons (BOP) facilities during the pandemic. Transcripts were coded and analyzed, using a thematic analysis approach.Results Many facilities implemented universal “lockdowns,” with time out of the (...) cell often limited to one hour per day, with participants reporting not being able to meet all essential needs such as showers and calling loved ones. Several study participants reported that repurposed spaces and tents created for quarantine and isolation provided “unlivable conditions.” Participants reported receiving no medical attention while in isolation, and staff using spaces designated for disciplinary purposes (e.g., solitary housing units) for public health isolation purposes. This resulted in the conflation of isolation and discipline, which discouraged symptom reporting. Some participants felt guilty over potentially causing another lockdown by not reporting their symptoms. Programming was frequently stopped or curtailed and communication with the outside was limited. Some participants relayed that staff threatened to punish noncompliance with masking and testing. Liberty restrictions were purportedly rationalized by staff with the idea that incarcerated people should not expect freedoms, while those incarcerated blamed staff for bringing COVID-19 into the facility.Conclusions Our results highlighted how actions by staff and administrators decreased the legitimacy of the facilities’ COVID-19 response and were sometimes counterproductive. Legitimacy is key in building trust and obtaining cooperation with otherwise unpleasant but necessary restrictive measures. To prepare for future outbreaks facilities must consider the impact of liberty-restricting decisions on residents and build legitimacy for these decisions by communicating justifications to the extent possible.

In this paper I shall venture into an area with which I am not very familiar and in which I feel far from confident; namely into phenomenology. My main motive is not to get away from standard, boring, methodological questions like those of induction and demarcation; but the conviction that a phenomenological account of the empirical basis forms a necessary complement to Popper's falsificationism. According to the latter, a scientific theory is a synthetic and universal, hence unverifiable proposition. In fact, (...) in order to be technologically useful, a scientific hypothesis must refer to future states-of-affairs; it ought therefore to remain unverified. But in order to be empirical, a theory must bear some kind of relation to factual statements. According to Popper, such a relation can only be one of potential conflict. Thus a theory T will be termed scientific if and only if T is logically incompatible with a so-called basic statement b, where b is both empirically verifiable and empirically falsifiable. In other words: T is scientific if it entails ¬b; where b, hence also ¬b, is an empirically decidable proposition. (shrink)

Domestic livestock animals and soils must be considered together as part of an agroecosystem which includes plants. Soil sustainability may be simply defined as the maintenance of soil productivity for future generations. There are both positive and negative aspects concerning the role of animals in soil sustainability. In a positive sense, agroecosystems which include ruminant animals often also include hay forage-or pasture-based crops in the humid regions. Such crops stabilize the soil by decreasing erosion, improving soil structure and usually require (...) fewer chemical inputs. Monogastric animal culture is based on an agroecosystem consisting of mainly grain crops. These crops can result in the soil being exposed to water and wind erosion although soil conservation practices that significantly reduce soil losses may be followed. The management of animal manures is not always compatible with soil conservation practices. Careful management of the nutrients in manure is absolutely necessary to avoid nitrate contamination of ground water or phosphorus loading of streams and lakes. In a negative sense, increases in animal livestock populations in association with human population growth are promoting desertification in the arid and semi-arid regions of the world. The key component for a fully compatible and acceptable association between domestic animals and soil productivity is proper management. Careful management of the components of an animal-based agroecosystem is required if soil productivity and environmental quality are to be maintained. Although we have much to learn, technologies are available to move a considerable way towards this ideal state. (shrink)

We discuss a generalization of the standard notion of probability space and show that the emerging framework, to be called operational probability theory, can be considered as underlying quantal theories. The proposed framework makes special reference to the convex structure of states and to a family of observables which is wider than the familiar set of random variables: it appears as an alternative to the known algebraic approach to quantum probability.

We study the possibility of representing the proposition lattice associated with a quantum system by a linear vector space with coefficients from ap-adic field. We find inconsistencies if the lattice is assumed, as usual, to be irreducible, complete, orthocomplemented, atomic, and weakly modular.

The probability pattern emerging in two-slit experiments is a typical quantum feature whose essential ingredients are examined by translating them into the spin- $ \frac{1}{2} $ formalism. In view of the existence of extensions of quantum theory preserving some classical structure, we discuss how the two-slit probabilities behave under such extensions. We consider a generalization of the standard classical probability theory, to be called operational probability theory, that turns out to host the so called quantum probabilities.
