Supercommentary, with commentaries on Praśastapādabhāṣya, a work on Kaṇāda's Vaiśeṣikasūtra, treatise on the Vaiśeṣika school in Hindu philosophy.

Connectives and cue phrases are the most prototypical linguistic elements that signal coherence relations, but by limiting our attention to connectives, we are likely missing out on important other cues readers and listeners use when establishing coherence relations. However, defining the role of other types of linguistic elements in the signaling of coherence relations is not straightforward, and it is also not obvious why and how non-connective elements function as signals for coherence relations. In this paper, we aim to develop (...) a systematic way of categorizing segment-internal elements as signals of coherence relations on the basis of a literature review and evidence from parallel corpora. We propose a three-way distinction betweendivision of labor, agreement, andgeneral collocationto categorize the different ways in which elements inside discourse segments interact with connectives in the marking of coherence relations. In each type of interaction, segment-internal elements can function as signals for coherence relations, but the mechanism behind it is slightly different for each type. (shrink)

I begin with a typology of reasoning and cross it with types of processes. I demonstrate that the thrust of Plato’s Republic is theory-building. This involves the critical and dialectic processes which are paradigms of Platonic methodology. Book I displays abductive analogical reasoning joined by an induction that is embedded in a deduction; hence there is a deduction–induction–abduction chain. In Book VI, Plato constructs a visual model of the divided line, which also displays model-based and abductive hypothesis generation that is (...) essential to theory building. Book VII provides an abductive metaphor model of the allegory of the cave. Both models depict degrees of reality and the ascendency of knowledge. The multimodal model-based allegory has far reaching applications from criminal justice to information systems. I conclude by capturing the narrative of the Republic as a critical and dialectic process of theory building using deductive–inductive–abductive chains, an abductive visual model and an abductive metaphor model. Hence, the Republic is simultaneously a masterpiece of deductive reasoning and a marvel of complex model-based abduction, involving visual models, analogies and metaphors. (shrink)

Abduction* is the genus with deduction and induction as species. Modus tollens is backward reasoning as an unknown proposition is inferred from a known proposition. Reductio ad absurdum is abductive because the conclusion is inferred by deriving a contradiction from an assumption. Inductive reasoning from effect to cause is also backward reasoning. But abduction* consists of forward reasoning as well. The generic structure of abductive* argumentation is universal among all cultures, occupations and disciplines.

First, ‘Is Justified True Belief Knowledge’ is imprecise but Gettier is explicit that ‘know’ is analysed as the definiendum is ‘S knows that P’. Second, Gettier does not misrepresent as Plato’s definition as the expressions used are ‘Plato considers’ and ‘seems to accept’. Third, Gettier is not mistaken to apply Plato’s definition to propositions since propositional knowledge is a species of Plato’s definition. Fourth, for Plato true belief temporally precedes an account. ‘Jones owns a Ford’ is never a true opinion, (...) hence no account for it can be given. The counterexample is reconstructed with temporality built into it. Fifth, Gettier does not fail to establish the equivalence of ‘believe’, ‘accepts’ and ‘sure’ in the three versions as this is implicitly established in the shifts made in the paper. Sixth, ‘entails’ logically is used only when the entailing proposition is true, but in the counterexamples a false proposition is taken to imply a true one. ‘Entail’ is to be taken in the ordinary sense of implies. Seventh, in Case I, the implication is preserved with the proper representation: → [Gy ↔ ], which implies { → [Gy ↔ ]}’. Eighth, the counterexample is reworked to avoid the objection that justification for p and justification for q may not be sufficient justification for ‘p & q’. (shrink)

I argue for the possibility of knowledge by invention whch is neither á priori nor á posteriori. My conception of knowledge by invention evolves from Poincaré’s conventionalism, but unlike Poincaré’s conventions, propositions known by invention have a truth value. An individuating criteria for this type of knowledge is conjectured. The proposition known through invention is: gounded historically in the discipline to which it belongs; a result of the careful, sincere and objective quest and effort of the knower; chosen freely by (...) the inventer or knower; and, private in its invention but public once invented. I extend knowledge by invention to include the knowledge of the invented proposition by those who do not invent it but accept it as a convention for good reasons. Finally, knowledge by invention combined with a revisionist, Platonist definition of knowledge as actively justified true belief provides a pedagogical model reviving the proactive spirit of the Socratic method with an emphasis on invention and activity and a de-emphasis on information gathering and passivity.

The inclusion of the truth condition in the definition of knowledge has been responsible for a number of paradoxes. Some epistemologists claim that in the case of knowledge justification entails truth or that belief implies truth as there is a causal relation between truth and belief. Truth hence becomes redundant in the definition of knowledge. I do not drop the truth condition for this reason because this denies the autonomy of the distinct conditions for knowledge. I argue that truth and (...) knowledge are inseparable. However. “that p is true” should not be a necessary condition in the definiens of the definiendum “S knows that p is true.” Whereas the quest of truth is a necessary condition for knowledge. While I drop the truth condition from the definition of knowing that p is true, I do not dropthe condition that p is false from the definition of knowing that p is false. This means that though I may know something that is not true, I cannot know something that is false. This is a compromised revision of the long standing intuition of epistemologists that if I know something then I cannot be wrong. Linda Zagzebski defines knowledge as: “Knowledge is a state of true belief arising out of acts of intellectual virtue.” (Zagzebski, 1996, 271). She has hence dropped the truth condition. Intellectual virtues direct us towards truth but they do not guarantee truth. In the ideal case whatever I know will be true, but in most cases it will be true to the best of my knowledge. (shrink)

In a Realist ontology relations are subsisting or existing entities distinct from ordinary things. Idealists claim that the notion of relations is subject to a vicious infinite regress. Nominalists claim that relations are particularized instances. In an attempt to search for the roots of a Realist conception of relations and to meet these challenges I investigate Plato's conception of relations in the Phaedo. ;Against the current of a majority of Plato scholars, Castaneda finds evidence for a distinction between relations and (...) properties at Phaedo 102 b-d. I enter the debate on Castaneda's side and find support for his interpretation of the passage in the context of the dialogue as a whole. The relation--quality distinction resolves the paradox of Simmias being both taller than Socrates and shorter than Phaedo at the same time, since Plato possesses relational characteristics of tallness and shortness, which are not contraries unlike the the contrary properties of hot and cold which could not coexist in an individual. Gallop offers the alternative essence--accident distinction which also resolves the paradox since tallness and shortness as accidents may coexist. The latter distinction however Aristotelianizes Plato. I have shown how the essence--accident distinction is incompatible with Plato's theory of Forms, as it leads to such odd conclusions as the admittance of accidental Forms. ;Castaneda claims that Plato reduces relations to Form-chains in which individuals participate in pairs. I offer the alternative of Plato's positing of relational Forms as distinct from monadic Forms. I survey the corpus of Platonic dialogues in search of support for the distinction between relations and properties. I find that in the Statesman there is a distinction between two types of Forms which generates the distinction between monadic Forms and relational Forms. ;I conclude that there is ample evidence in Plato's dialogues and in Aristotle's assessment of Plato to ascribe this distinction to Plato. Plato's explanation of relations in terms of Forms, which have the highest grade of reality for him, sets up the basis for any Realist theory of relations--for reductionist theories reducing relations to relational properties or some other subsisting entities, as well as for the irreducible concept of relations as abstract subsisting entities.

The prevention, treatment and management of disease are closely linked to how the causes of a particular disease are explained. For multi-factorial conditions, the causal explanations are inevitably complex and competing models may exist to explain the same condition. Selecting one particular causal explanation over another will carry practical and ethical consequences that are acutely relevant for health policy. In this paper our focus is two-fold; the different models of causal explanation that are put forward within current scientific literature for (...) the high and rising prevalence of the common complex conditions of coronary artery disease and type 2 diabetes mellitus ; and how these explanations are taken up within national health policy guidelines. We examine the causal explanations for these two conditions through a systematic database search of current scientific literature. By identifying different causal explanations we propose a three-tier taxonomy of the most prominent models of explanations: evolutionary, lifecourse, and lifestyle and environment. We elaborate this taxonomy with a micro-level thematic analysis to illustrate how some explanations are semantically and rhetorically foregrounded over others. We then investigate the uptake of the scientific causal explanations in health policy documents with regard to the prevention and management recommendations of current National Service Frameworks for CAD and T2D. Our findings indicate a lack of congruence between the complexity and frequent overlap of causal explanations evident in the scientific literature and the predominant focus on lifestyle recommendations found in the mainstream health policy documents.

Mastery imagery has been shown to be associated with more positive cognitive and emotional responses to stress, but research is yet to investigate the influence of mastery imagery ability on imagery’s effectiveness in regulating responses to acute stress, such as competition. Furthermore, little research has examined imagery’s effectiveness in response to actual competition. This study examined (a), whether mastery imagery ability was associated with stress response changes to a competitive stress task, a car racing computer game, following an imagery intervention, (...) and (b), the effects of different guided imagery content on pre-task cognitive and emotional responses. In Session 1, 78 participants (M age = 20.03 years, SD = 1.28) completed ratings of pre-task anxiety intensity and direction, confidence, and perceived control. Imagery ability was also assessed before completing the task. In Session 2, participants were randomly allocated to an imagery condition (positive mastery, negative mastery, relaxation) or control group (no imagery) before completing the task and outcome measures again. For the negative mastery group, greater positive mastery imagery ability was associated with greater perceived control and perceiving anxiety as more facilitative. Furthermore, mastery imagery ability moderated the relationship between anxiety intensity and direction. Altogether, results suggest that positive mastery imagery ability may act as a potential buffer against the effects of negative images. (shrink)

Background:The severity of the Coronavirus pandemic has led to lockdowns in different countries to reduce the spread of the infection. These lockdown restrictions are likely to be detrimental to mental health and well-being in adolescents. Physical activity can be beneficial for mental health and well-being; however, research has yet to examine associations between adolescent physical activity and mental health and well-being during lockdown.Purpose:Examine the effects of adolescent perceived Coronavirus prevalence and fear on mental health and well-being and investigate the extent (...) to which physical activity can be a protective factor against these concerns.Methods:During United Kingdom lockdown restrictions, 165 participants (100 female, aged 13–19) completed an online questionnaire assessing perceived Coronavirus prevalence and fear, physical activity, and indicators of mental health and well-being (stress, anxiety, depression, fatigue, vitality, and perceived health). Separate hierarchical multiple linear regression analyses (with age, gender, perceived Coronavirus prevalence, and fear entered in step 1, and physical activity in step 2) were run to predict each well-being outcome.Results:Regression analyses indicated that in general, while Coronavirus fear was a negative predictor, physical activity was a positive and stronger predictor of enhanced mental health and well-being outcomes.Conclusion:Findings suggest that physical activity during the Coronavirus pandemic can counteract the negative effects of Coronavirus fear on adolescent mental health and well-being. Therefore, physical activity should be promoted during lockdown to support good mental health and well-being. (shrink)

In two pre-registered online studies during the COVID-19 pandemic and the early 2020 lockdown (one of which with a UK representative sample) we elicit risk-tolerance for 1,254 UK residents using four of the most widely applied risk-taking tasks in behavioral economics and psychology. Specifically, participants completed the incentive-compatible Balloon Analog Risk Task (BART) and the Binswanger-Eckel-Grossman (BEG) multiple lotteries task, as well as the Domain-Specific Risk-Taking Task (DOSPERT) and the self-reported questions for risk-taking used in the German Socio-economic Panel (SOEP) (...) study. In addition, participants in the UK representative sample answered a range of questions about COVID-19-related risky behaviors selected from the UCL COVID-19 Social Survey and the ICL-YouGov survey on COVID-19 behaviors. Consistently with pre-COVID-19 times, we find that risk tolerance during the UK lockdown (i) was higher in men than in women and (ii) decreased with age. Undocumented in pre-COVID-19 times, we find some evidence for healthier participants displaying significantly higher risk-tolerance for self-reported risk measures. We find no systematic nor robust patterns of association between the COVID-19 risky behaviors and the four risk-taking tasks in our study. Moreover, we find no evidence in support of the so-called “risk compensation” hypothesis. If anything, it appears that participants who took greater risk in real-life COVID-19-relevant risky behaviors (e.g., isolating or taking precautions) also exhibited higher risk-tolerance in our experimental and self-reported risk-taking measures.

The need for research to advance scientific understanding must be balanced with ensuring the rights and wellbeing of participants are safeguarded, with some research topics posing more ethical quandaries for researchers than others. Moral injury is one such topic. Exposure to potentially morally injurious experiences can lead to significant distress, including post-traumatic stress disorder, depression, and selfinjury. In this article, we discuss how the rapid expansion of research in the field of moral injury could threaten the wellbeing, dignity and integrity (...) of participants. We also examine key guidance for carrying out ethically responsible research with participants’ rights to self-determination, confidentiality, non-maleficence and beneficence discussed in relation to the study of moral injury. We describe how investigations of moral injury are likely to pose several challenges for researchers including managing disclosures of potentially illegal acts, the risk of harm that repeated questioning about guilt and shame may pose to participant wellbeing in longitudinal studies, as well as the possible negative impact of exposure to vicarious trauma on researchers themselves. Finally, we offer several practical recommendations that researchers, research ethics committees and other regulatory bodies can take to protect participant rights, maximise the potential benefits of research outputs and ensure the field continues to expand in an ethically responsible way.

Mastery imagery (i.e., images of being in control and coping in difficult situations) is used to regulate anxiety. The ability to image this content is associated with trait confidence and anxiety, but research examining mastery imagery ability's association with confidence and anxiety in response to a stressful event is scant. The present study examined whether trait mastery imagery ability mediated the relationship between confidence and anxiety, and the subsequent associations on performance in response to an acute psychological stress. Participants (N= (...) 130; 55% male;Mage= 19.94 years;SD= 1.07 years) completed assessments of mastery imagery ability and engaged in a standardized acute psychological stress task. Immediately prior to the task, confidence, cognitive and somatic anxiety intensity, and interpretation of anxiety symptoms regarding the task were assessed. Path analyses supported a model whereby mastery imagery ability mediated the relationship between confidence and cognitive and somatic anxiety interpretation. Greater mastery imagery ability and confidence were both directly associated with better performance on the stress task. Mastery imagery ability may help individuals experience more facilitative anxiety and perform better during stressful tasks. Improving mastery imagery ability by enhancing self-confidence may help individuals successfully cope with anxiety elicited during stressful situations. (shrink)

The Coronavirus pandemic has significantly affected psychological wellbeing in older adults, with cases of depression, anxiety and loneliness rising in the general population. Cognitive health has also potentially been affected, as social isolation can lead to cognitive decline. Worrying about cognitive health can be damaging to psychological wellbeing and is especially relevant to explore in the context of the Coronavirus pandemic. The objective of the present study was to explore the associations between cognitive health worries and wellbeing, and to investigate (...) whether physical activity and social contact can mitigate negative effects of the pandemic on psychological wellbeing. Older adults completed an online survey which included measures of cognitive health worries, depression, anxiety, loneliness, social isolation, fatigue, impact of the Coronavirus pandemic, quality of life, subjective vitality, and physical activity. Analyses indicated that cognitive health worries, lower levels of physical activity and smaller amounts of social interaction were associated with poorer psychological and physical wellbeing. Results showed that worrying about cognitive health is associated with poorer wellbeing, and so interventions are needed to encourage positive cognitive functioning in times of social isolation. Promoting physical activity and social interaction is also beneficial, as results show that exercise and social contact are linked with improved wellbeing. (shrink)

Animal data suggest that jet fuels such as JP-8 are associated with hearing deficits when combined with noise and that the effect is more pronounced than with noise exposure alone. Some studies suggest peripheral dysfunction while others suggest central auditory dysfunction. Human data are limited in this regard. The aim of this study was to investigate the possible chronic adverse effects of JP-8 combined with noise exposure on the peripheral and central auditory systems in humans. Fifty-seven participants who were current (...) personnel from the Royal Australian Air Force were selected. Based on their levels of exposure to jet fuels, participants were divided into three exposure groups. Groups were also categorised based on their noise exposure levels. All participants were evaluated by tympanometry, pure-tone audiometry, distortion product otoacoustic emissions, auditory brainstem response, words-in-noise, compressed speech, dichotic digit test, pitch pattern sequence test, duration pattern sequence test and adaptive test of temporal resolution. All auditory tests were carried out after the participants were away from the Air Force base for a minimum of two weeks, thus two weeks without jet fuel and noise exposure. Jet fuel exposure was significantly associated with hearing thresholds at 4 and 8 kHz; average hearing thresholds across frequencies in the better ear; DPOAEs at 2.8, 4 and 6 kHz; ABR wave V latency in the right ear; compressed speech and words-in-noise. Further analyses revealed that participants with low exposure level to jet fuels showed significantly better results for the aforementioned procedures than participants with moderate and high exposure levels. All results were controlled for the covariates of age and noise exposure levels. The results suggest that jet fuel exposure, when combined with noise exposure, has an adverse effect on audibility in humans. Taking all the test results into consideration, jet fuel exposure combined with noise exposure specifically seems to affect the peripheral hearing system in humans. (shrink)

Models of purgatory tend to come paired with an operative conception of what perfection consists in. In the recent philosophical literature, two models, the satisfaction model and the sanctification model, have been pitted against one another. The former focuses on innocence before the law and makes purgatory out to be a place where a debt of punishment is paid. The latter focuses on moral character and describes purgatory in terms of character formation. If perfection consists in a certain way of (...) being related to God, however, then there is a third model that merits our attention that focuses on relational dynamics. (shrink)

It is shown that the Lorentz-deformation property discussed in previous papers is consistent with the hadronic jet phenomenon in high-energy production processes.

Global crises such as the climate crisis require fast concerted action, but individual and structural barriers prevent a socio-ecological transformation in crucial areas such as the mobility sector. An identification with people all over the world and an openness toward less consumption may represent psychological drivers of a socio-ecological transformation. We examined the compatibility of both concepts as well as their relation to people’s support of a decarbonised mobility system and their flight mobility behaviour – a CO2-intensive behaviour that may (...) be particularly difficult to refrain from for globally identified people, but less so for sufficiency-oriented people. In an online study conducted in Germany, we found that global identity and sufficiency orientation were positively related. Both were negatively related to past flight-related CO2 emissions and positively related to refraining from flying and the support of decarbonised mobility policies. Accounting for both showed that sufficiency orientation in particular was related to fewer flight-related CO2 emissions and refraining from flying. Furthermore, we examined people’s travel experiences. While global identity was unrelated to the frequency and duration of international travelling, it was positively related to the frequency and quality of contact with local people met on journeys. An experimental variation of whether participants first answered questions on global identity or on travel experiences revealed that remembering past international travelling led to higher reported levels of global identity. Taken together, global identity seems to profit from in-depth international contact with people, but can be decoupled from resource-intensive travel behaviour. Globally identified and sufficiency-oriented people may support a socio-ecological transformation. Our results indicate a compatibility of global identity and sufficiency orientation. Experimental and longitudinal research should examine causal links to foster our understanding of the conditions under which both can be strengthened. (shrink)

It is shown that the jet mechanism derivable from the Lorentz deformation picture leads to a nearly constant average jet transverse momentum. It is pointed out that this is consistent with the high-energy experimental data. It is pointed out further that this result strengthens the physical basis for the minimal time-energy uncertainty combined covariantly with Heisenberg's space-momentum uncertainty relation.

Cet article se propose d’appréhender le segment du point de vue de la production, en analysant les séquences identifiées lors du processus d’écriture, c’est-à-dire les unités langagières produites de manière spontanée et ininterrompue (entre deux pauses). Ces unités, que nous appelons jets textuels, ont été enregistrées grâce à l’outil de suivi de rédaction Inputlog. Nous avons tenté de caractériser les jets textuels en les mettant en regard avec divers types d’unités segmentales de langage, qu’elles soient issues de la segmentation des (...) textes finalisés, ou reconnues comme des segments préfabriqués propres à un système lexical ou syntaxique, c’est-à-dire des figements au sens large du terme. Nous nous sommes plus particulièrement penchés sur un parcours de segmentation parallèle, en production (jets textuels) et en réception (segments répétés), pour interroger quelques concepts théoriques et méthodologiques qui sous-tendent les démarches de segmentation : pré-construit, automatisme, mémorisation, figement, enracinement cognitif, fréquence, répétition.
