In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Studies in Plato's Two-Level ModelIan MuellerHolger Thesleff. Studies in Plato's Two-Level Model. Helsinki: Societas Scientarum Fennica, 1999. Pp. vi + 143. N. P.After some 30 years of incisive intervention in Platonic scholarship, Holger Thesleff here offers us "an attempt to elaborate and ground more firmly some basic theses which I have propounded in various contexts before," (1) a rather modest description of what he also describes (...) as an attempt to contribute toward "a more general agreement on how to read and interpret Plato" (5). The richness of this book makes it impossible to describe in any detail, and I shall content myself with indicating some of what I take to be its principal points of view.Thesleff"s concern for agreement arises from his perception of the vastly discrepant schools of Plato interpretation, of which the most important for him might be labeled esotericist, analytic, and "literary." The last, which can hardly be called a school at all, includes a variety of scholars who downplay "literal" interpretation and emphasize such things as "dramatic artistry, the structure of the dialogues, the characterization of settings and persons, shifts of style, allusions, play, and irony" (3). Thesleff's sympathies clearly lie with these people, perhaps to an extent which, as I shall suggest, will limit the effectiveness of his attempt to move toward a consensus.As the title indicates Thesleff builds his reading around what he calls Plato's two-level model. This two-level model is not, as one might suppose, what has been called Plato's two worlds view, the belief in a world of pure being beyond the perceived world we inhabit. Indeed, it is not a doctrine or set of doctrines at all. Rather "it is an intuitive 'vision' which offers only crude basic patterns and frames for the structures of Plato's thinking, feelings, intuitions, and intentions, from his youth to his old age, and for our understanding of them" (123). Clearly one cannot expect a full and precise articulation of this vision. Thesleff proceeds by discussing in terms of their role in the earlier dialogues ten hierarchic pairs which form part of Plato's vision: divine/human, soul/body, leading/being led (particularly important in the conduct of a Socratic discussion), truth/appearance, knowledge/opinion, intellect/senses, defined/undefined, stability/change, one/many, same/different. These hierarchic or asymmetric pairs are contrasted by Thesleff with what he calls polar opposites like large/small and light/dark. He also stresses that the hierarchic pairs of Plato's two-level model involve no separation (chorismos), but rather a communion (koinônia).As the words "from his youth to his old age" in the quotation of the previous paragraph indicate, Thesleff is a "unitarian" in his approach to Plato. His Plato is not a philosopher whose positions changed through time as a result of reasoned argument. What many scholars take to be doctrines later given up, e.g., the view that learning is being reminded (anamnêsis), are "thought experiments," which are not followed up, thought experiments made within the context of the unchanging two-level vision.Although Thesleff is a unitarian in the sense I have indicated, he does believe that a kind of order of composition can be constructed for the dialogues. I say "kind of" because Thesleff's chronology involves assumptions of revisions over time, multiple authorship, and even dialogues "written down" by people other than Plato. The resulting chronology is complex, and I here only indicate it in rough form in a way which [End Page 272] brings out what I take to be its major points. Leaving out of account those Socratic" dialogues which Thesleff takes to be latish and the posthumously completed Laws, we can say that a series of late dialogues starts with the Parmenides and includes the Timaeus, Critias, Sophist, Politicus, and Philebus. All other dialogues, including the Theaetetus, were written prior to the Parmenides with the exception of the Republic, which Thesleff proposes is in its ultimate shape a late work, representing "only and purely Plato's 'own' and personal philosophy" (115). As for the other late dialogues, which have played an important... (shrink)

This paper proposes a two-level modeling perspective which combines intrinsic 'betterness' and reason-based extrinsic preference, and develops its static and dynamic logic in tandem. Our technical results extend, integrate, and re-interpret earlier theorems on preference representation and update in the literature on preference change.

Luck egalitarianism has come under a lot of criticism for its apparent harshness towards negligent victims of voluntary actions (the harshness objection) and its inability to respond to morally-acceptable voluntary acts that lead to disadvantage (the discrimination objection). This paper surveys a series of responses in the luck egalitarian literature, showing that for the most part each one is unable to respond, on its own, to the crux of the objections. These responses often face a dilemma: Either they must bite (...) the bullet on the objections to retain their luck egalitarian commitments, or they must propose a reply to the objection that diverges from their core luck egalitarian principles. In this paper, I advance a preliminary framework for grounding luck egalitarian theories of justice based upon a two-level model and what I shall call the Fact of Inherent Normativity. Two-level luck egalitarianism makes fundamental rights and basic needs de facto insensitive to responsibility at the first level, while retaining the scope for responsibility for the distribution of second-level goods. The account remains distinctly luck egalitarian, while leaving scope for the consideration of rights, respect, and a host of other morally relevant considerations within the luck egalitarian framework. Luck egalitarianism, properly understood as a two-level theory, can successfully respond to objections against its harshness and propensity to discriminate. (shrink)

헤어의 아크라시아에 관한 전기 입장을 살펴보면, 진실한 도덕 판단에 이르는 한, 아크라시아 현상은 불가능한 것이다. 하지만 헤어의 아크라시아에 관한 전기 입장은 언어 논리에 지나치게 치중한 나머지, 현실에서 종종 볼 수 있는 도덕적 갈등, 죄책감, 후회와 같은 일상의 경험을 설명하는 데 부족하다는 비판을 받는다. 이와 달리 헤어의 아크라시아에 관한 후기 입장은 인간학적 한계를 고려하여 현실의 인간을 설명함으로써 아크라시아 문제에 관해 좀 더 설득력 있는 논의를 펼친다. 헤어의 아크라시아에 관한 후기 입장은 도덕적 사유의 두 수준 이론을 통해, 아크라시아에 관한 논의를 2가지 관점에서 (...) 분석하여 아크라시아 문제를 바라본다. 즉, 비판적 수준의 도덕적 사유를 하게 되면 아크라시아 현상이 불가능하다는 입장을 따르게 되지만, 직관적 수준의 도덕적 사유를 하게 되면 아크라시아 현상은 가능한 것이다. 하지만 헤어의 아크라시아 논의가 타당성을 지니기 위해서는 실험윤리학의 연구 성과를 바탕으로 면밀히 검토하고 그 한계를 분석해 볼 필요가 있다. 비판적 수준의 도덕적 사유의 측면에서 바라본 아크라시아 문제에 관한 검토는 도덕주의자가 현실적으로 존재 가능성 유무와 설사 있다 하더라도 그들을 확인할 수 있는 객관적인 방법이 없기 때문에 실험윤리학적으로 검토하기는 쉽지 않을 것이다. 또한, 직관적 수준의 도덕적 사유의 측면에서 바라본 아크라시아 문제를 검토하기 위해 vmPFC 손상 환자에 관한 다양한 연구 결과를 살펴보았지만, 여전히 헤어의 아크라시아 문제를 정당화하기 위해서는 더 많은 경험 과학적 증거들이 필요한 시점이다. 결국, 헤어의 아크라시아 문제에 관한 논의는 더 많은 경험 과학적 증거를 통해 학문적 실효성이 검증될 필요가 있다. 따라서 제한된 연구 성과를 바탕으로 단정적인 결론을 내리는 것은 바람직하지 않기 때문에, 실험윤리학적 증거를 바탕으로 철저히 검토하여 더 나은 방향으로 발전하고 진화되어야 할 것이다.

We present a two-level theory to formalize constructive mathematics as advocated in a previous paper with G. Sambin.One level is given by an intensional type theory, called Minimal type theory. This theory extends a previous version with collections.The other level is given by an extensional set theory that is interpreted in the first one by means of a quotient model.This two-level theory has two main features: it is minimal among the most relevant foundations for constructive mathematics; (...) it is constructive thanks to the way the extensional level is linked to the intensional one which fulfills the “proofs-as-programs” paradigm and acts as a programming language.

Emotion recognition plays an important part in human-computer interaction. Currently, the main challenge in electroencephalogram -based emotion recognition is the non-stationarity of EEG signals, which causes performance of the trained model decreasing over time. In this paper, we propose a two-level domain adaptation neural network to construct a transfer model for EEG-based emotion recognition. Specifically, deep features from the topological graph, which preserve topological information from EEG signals, are extracted using a deep neural network. These features are then passed (...) through TDANN for two-level domain confusion. The first level uses the maximum mean discrepancy to reduce the distribution discrepancy of deep features between source domain and target domain, and the second uses the domain adversarial neural network to force the deep features closer to their corresponding class centers. We evaluated the domain-transfer performance of the model on both our self-built data set and the public data set SEED. In the cross-day transfer experiment, the ability to accurately discriminate joy from other emotions was high: sadness, anger, and fear on the self-built data set. The accuracy reached 74.93% on the SEED data set. In the cross-subject transfer experiment, the ability to accurately discriminate joy from other emotions was equally high: sadness, anger, and fear on the self-built data set. The average accuracy reached 87.9% on the SEED data set, which was higher than WGAN-DA. The experimental results demonstrate that the proposed TDANN can effectively handle the domain transfer problem in EEG-based emotion recognition. (shrink)

I present—in an extremely sketchy form—a model of two-level, open, plastic and multidimensional human nature. Due to the included attribute of multidimensionality this model opposes the reductive conceptions of man dominating in today’s philosophy. The main objective of the paper is the ontological status of man, especially the ontic foundation of multidimensional man. I demonstrate that this status remains a riddle; one only knows that from the ontological perspective man is a wholly exceptional object, not explainable by to-date ontological (...) constructions. -/- .

In this commentary, I advocate for strict relations between Marr's levels of analysis. Under a strict relationship, each level is exactly implemented by the subordinate level. This yields two benefits. First, it brings consistency for multilevel explanations. Second, similar to how a sculptor chisels away superfluous marble, a modeler can chisel a computational-level model by applying constraints. By sculpting the model, one restricts the set of possible algorithmic- and implementational-level theories.

This paper examines the impact of environmental, social and governance (ESG) disclosure scores on the firm value of European listed companies before, during and after the COVID-19 pandemic. Using a two-level model and a unique dataset of 264 multinational firms covering the period 2019–2022, we find a negative relationship between ESG disclosure scores and firm value. Nevertheless, the effect of the social and environmental disclosure scores disappears during the crisis, and returns negative during the recovery period. Almost all empirical (...) studies to date have found the inverse effect, suggesting that even though ESG transparency can improve firm reputation, it can also damage it and reduce firm value. We also show that firm-specific factors remain the biggest source of variability in firm value, even during the crisis. Thus, this paper contributes to the existing literature by suggesting that the impact of ESG disclosure on firm value may vary depending on the economic and financial context in which firms operate. More specifically, it shows that the benefits of ESG disclosure, namely the reduction of agency costs, stakeholder trust, and firm legitimacy, which are expected to increase firm value, may not have the predicted effect in a crisis context. Consequently, these findings provide both an empirical and a theoretical contribution to the existing literature on agency theory, signal theory, and legitimacy theory. (shrink)

In this paper, a two-level green supply chain composed of a manufacturer and a retailer is taken as the background. Considering the consumer’s double consumption preference and the manufacturer’s green product R&D investment, a differential game model of the green supply chain under the government cost subsidy strategy is constructed. Firstly, the equilibrium points of the system are solved and their stability is discussed and analyzed. Secondly, the dynamic evolution process of Nash equilibrium under the parameters of green degree, (...) green preference coefficient, retail channel preference coefficient, coefficient of the sensitivity of price, and adjustment speed are described by numerical simulation. The results show that the two ways of a system entering chaos are Flip bifurcation and N-S bifurcation, respectively, by 2D bifurcation graph, and it is also verified in 1D bifurcation diagram. When the bifurcation parameters are small, the system maintains Nash equilibrium stability. If the green degree of products is increased, the green preference coefficient will also increase; on the contrary, the retail preference coefficient will decrease. Research and development cost subsidy policy can effectively improve the green degree of products and increase the sales volume of products, so as to improve the profit of supply chain members.

It is well known that working memory performance changes with age. Two recent computational models of working memory, TBRS* and SOB-CS, developed from young adults WM performances are opposed regarding the postulated causes of forgetting, namely time-based decay and interference for TBRS* and SOB-CS, respectively. In the present study, these models are applied on a set of complex span data produced by young and older adults. As expected, these models are unable to account for the older adult (...) data. An investigation on the effect of the main parameters of these models showed that the poorer performance of older adults does not come from a weaker encoding of item but rather from difficulties during the free time that immediately follows each distractor, as well as from a higher level of confusion between items. These results are discussed with respect to the current theories of working memory and aging. (shrink)

Verbs likeloadorsprayare known to alternate between two variants (John sprayed paint onto the wall / John sprayed the wall with paint ). Both Rappaport and Levin (1988) and Pinker (1989) derive one variant from the other, but these lexical rule approaches have a number of problems. This paper argues for a form-meaning correspondence model which distinguishes between two levels of verb meaning: that of a lexical headsprayon the one hand and that of a phrasal constituentspray paint onto the wallorspray the (...) wall with painton the other. Locative alternation stems from the fact that a frame semantic scene encoded byspraycan be construed in two alternate ways. This proposed model allows us to account for the data straightforwardly without suffering from the problems created by lexical rule approaches. This proposed analysis is fundamentally the same as Goldberg’s (1995) in being a version of Construction Grammar approach. But unlike Goldberg’s Correspondence Principle-based account, my analysis makes the most of the semantic compatibility between verbs and constructions, thereby giving a more straightforward account of locative alternation.

The main objective of this paper is to demonstrate why AI researchers’ attempts at developing projects of moral machines are a cause for concern regarding the way in which such machines can reach a certain level of morality. By comparing and contrasting Howard and Muntean’s model of a virtuous Artificial Autonomous Moral Agent and Bauer’s model of a two-level utilitarian Artificial Moral Agent, I draw the conclusion that both models raise, although in a different manner, some crucial (...) issues. The latter are recognized as deriving from the complex relationships between human cognition and moral reasoning, as refracted through the lens of the idea of moral AI. In this context, special attention is paid to the complications which are triggered by the analogical thinking regarding the processes of replication of human morality in the field of machine ethics.

We discuss two named-entity recognition models which use characters and character n-grams either exclusively or as an important part of their data representation. The first model is a character-level HMM with minimal context information, and the second model is a maximum-entropy conditional markov model with substantially richer context features. Our best model achieves an overall F1 of 86.07% on the English test data (92.31% on the development data). This number represents a 25% error reduction over the same model (...) without word-internal (substring) features. (shrink)

[About the book]: Neuroscience has long had an impact on the field of psychiatry, and over the last two decades, with the advent of cognitive neuroscience and functional neuroimaging, that influence has been most pronounced. However, many question whether psychopathology can be understood by relying on neuroscience alone, and highlight some of the perceived limits to the way in which neuroscience informs psychiatry. Psychiatry as Cognitive Neuroscience is a philosophical analysis of the role of neuroscience in the study of psychopathology. (...) The book examines numerous cognitive neuroscientific methods, such as neuroimaging and the use of neuropsychological models, in the context of a variety of psychiatric disorders, including depression, schizophrenia, dependence syndrome, and personality disorders. Psychiatry as Cognitive Neuroscience includes chapters on the nature of psychiatry as a science; the compatibility of the accounts of mental illness derived from neuroscience, information-processing, and folk psychology; the nature of mental illness; the impact of methods such as fMRI, neuropsychology, and neurochemistry, on psychiatry; the relationship between phenomenological accounts of mental illness and those provided by naturalistic explanations; the status of delusions and the continuity between delusions and ordinary beliefs; the interplay between clinical and empirical findings in psychopathology and issues in moral psychology and ethics. With contributions from world class experts in philosophy and cognitive science, this book will be essential reading for those who have an interest in the importance and the limitations of cognitive neuroscience as an aid to understanding mental illness.

The Group Cohesiveness Scale measures patient-rated group cohesiveness. The English version of the scale has demonstrated good psychometric properties. This study describes the validation of the Czech version of the GCS. A total of 369 patients participated in the study. Unlike the original study, the ordinal confirmatory factor analysis supported a two-dimensional solution. The analysis demonstrated the existence of two moderately to highly associated domains of group cohesiveness—affective and behavioral. The two-dimensional model was invariant across genders, age, education, and time (...) up to factor means level. Internal consistency reached satisfactory values for both domains. In terms of convergent validity, only weak association was found between the GCS domains and the group working alliance measured by the Group Outcome Rating Scale. This is the first revision of the factor structure of the GCS in the European context. The scale showed that the Czech version of the GCS is a valid and reliable brief tool for measuring both aspects of group cohesiveness. (shrink)

Many of the commentaries cohere around two major points of criticism. The first is that we have omitted discussion of the mechanisms that are assumed to operate at levels 2, 3, and 4.Campbell, Cloak, Dewsbury, Eckberg, Mundinger, Pulliam, Richerson & Boyd, Slobodkin, Simon, Williams, andWahlstenall make comments that bear on this point. The second point is that we have omitted discussion of the fact that "organisms change the environment by their activities" and thereby modify the selection pressures that act on (...) them. Apart from Lewontin, this point has been raised in different forms byBarkow, Chase, Hull, Perzigian, Ruyle, and less directly bySlobodkin. Stemming from these two basic omissions there is a third general criticism. Numerous commentators have pointed out that we have failed to discuss sufficiently either the extent or nature of the constraints that may or may not be operating on supraordinate evolutionary processes as a function of their nested relationships to subordinate evolutionary processes within our scheme. We start by acknowledging these three basic omissions. We agree that they exist and that they are serious. (shrink)

Following and extending Searle’s speech act theory, both Pragma-Dialectics and the Linguistic Normative Model of Argumentation characterize argumentation as an illocutionary act. In these models, the successful performance of an illocutionary act of arguing depends on the securing of uptake, an illocutionary effect that, according to the Searlean account, characterizes the successful performance of any illocutionary act. However, in my view, there is another kind of illocutionary effect involved in the successful performance of an illocutionary act of arguing, which (...) affects both the speaker’s and the hearer’s set of rights, obligations, and entitlements. In order to give an account of this second type of effect, I will argue that it is necessary to distinguish two levels in the analysis of the illocutionary act of arguing. The first one is related to the illocutionary effect of securing of uptake and thus to the speech act performed by the speaker, while the second one allows us to account for the changes produced by the performance of the illocutionary act of arguing in the deontic modal competence of both the speaker and the hearer.

During the COVID-19 epidemic, personal safety has received increasing attention, leading to behavioral changes. Mobile-wallet makes it easier for people to keep social distance, which helps stop the spread of the COVID-19 virus. Evolving Internet technology has brought about changes in consumer lifestyle. The current situation of COVID-19 has created a business environment to shift from traditional ways and adopt e-commerce solutions worldwide. Grounded in technology acceptance model theory, this study’s objective is two-fold: First, this study intends to examine perceived (...) susceptibility to COVID-19, perceived severity of COVID-19, insecurity and discomfort as the predictors of perceived usefulness and perceived ease of use. Second, the current research intends to test the moderating effect of electronic words-of-mouth on the relationship between attitude and usage intention. Using survey methods, 226 usable responses were collected through a mall intercept survey in Pakistan. Data were analyzed using partial least square. The results revealed that PEOU and PU positively influence attitude toward M-wallet. This study has found that attitude positively influences the usage intention in adopting M-wallet. The results also support the moderating role of eWOM. These findings contribute to the marketing literature in several ways, particularly in Pakistan. This is the first study to use eWOM as a moderating variable in the TAM theory. In addition, this study adds to the current body of knowledge by considering eWOM as a multi-dimensional construct novel in m-wallet literature. (shrink)

It is evident that, being a member of the organization, the team has to cue the influx of the green management concepts. This study focuses on the aspect of team management in green enterprises. Applying leadership theory to sample green enterprises, this paper proposes that political skills of team leadership have moderating effects on the relationship between team conflict and performance at both the individual and team levels. Empirical data were collected from 85 dyads of leaders and team members in (...) 36 green enterprises in China. It was found that the leaders’ political skills weakened the negative effects of relationship conflict on individual performance and team performance. Further, leaders’ political skills strengthened the positive effects of task conflict on individual and team performance. The results of this study deepen the cognition of two types of team conflict in theory and provide theoretical guidance for green enterprises in carrying out effective team conflict management and practical political skills training for leaders.

The “problem” of dreaming in NREM sleep continues to challenge models that propose a causal relationship between REM mechanisms and the psychological features of dreaming. I suggest that, ultimately, efforts to identify correspondences among multiple levels of analysis will be more productive for dream theory than attempts to reduce dreaming to any one level of analysis.

There are indications that the interpersonal affective factor and the social deviation factor, both of which are underlying dimensions of psychopathy, have a positive and a negative relationship, respectively, with executive functioning. However, this is seldom taken into consideration in the research on the relationship between executive functioning and psychopathy, which may be an explanation for the many inconsistent results in this area as reported in the literature (e.g., Rogers, 2006). In the present study, executive functioning was studied using the (...) Wisconsin Card Sorting Test (WCST) in 53 inpatients of a Dutch forensic psychiatric clinic who were classified by means of the Psychopathy Checklist-Revised (PCL-R). Special attention was given to the relationship between the two separate factors and executive functioning. Age, educational level, and substance abuse were controlled for in the analysis. No difference was found between psychopathic (N = 17) and nonpsychopathic (N = 36) patients in the WCST scoring categories, nor was there a significant difference in the four diagnostic subgroups defined by the two factors. However, the trends observed do justify further study in this direction. (shrink)

There is an increasing amount of empirical work investigating the sense of agency, i.e. the registration that we are the initiators of our own actions. Many studies try to relate the sense of agency to an internal feed-forward mechanism, called the ‘‘comparator model’’. In this paper, we draw a sharp distinction between a non-conceptual level of feeling of agency and a conceptual level of judgement of agency. By analyzing recent empirical studies, we show that the comparator model is (...) not able to explain either. Rather, we argue for a two-step account: a multifactorial weighting process of different agency indicators accounts for the feeling of agency, which is, in a second step, further processed by conceptual modules to form an attribution judgement. This new framework is then applied to disruptions of agency in schizophrenia, for which the comparator model also fails. Two further extensions are discussed: We show that the comparator model can neither be extended to account for the sense of ownership (which also has to be differentiated into a feeling and a judgement of ownership) nor for the sense of agency for thoughts. Our framework, however, is able to provide a unified account for the sense of agency for both actions and thoughts. (shrink)

The article revisits two basic questions of political theory posed by Jon Elster. First, should the political process be defined as private or public, and second, should its purpose be understood instrumentally or intrinsically? Having posed these questions, Elster arrives at three views of politics: social choice , republican and discourse theory . I argue for a fourth view , and explain Elster's omission of this model by referring to his underlying paradigm of politics, that is, as will formation. The (...) main thesis in Elster's article is about whether the process of will formation should be relegated to the market mechanism or dealt with via deliberative forums. I reject this paradigm and argue instead for politics as jurisdiction. This notion of politics is concerned with the question of how both market and forum processes of will formation should be institutionalized. Defining politics as jurisdiction strongly improves the plausibility of the missing fourth model of democratic will formation, as a depiction of democratic will formation as private in its process and intrinsic in its purpose illustrates the importance of distinguishing between two levels of democracy: namely, the civil level of will formation and the political level of jurisdiction.

Building on and partially refining previous theoretical work, this paper presents an extended simulation model of ancestral warfare. This model (1) disentangles attack and defense, (2) tries to differentiate more strictly between selfish and altruistic efforts during war, (3) incorporates risk aversion and deterrence, and (4) pays special attention to the role of brutality. Modeling refinements and simulation results yield a differentiated picture of possible evolutionary dynamics. The main observations are: (i) Altruism in this model is more likely to evolve (...) for defenses than for attacks. (ii) Risk aversion, deterrence and the interplay of migration levels and brutality can change evolutionary dynamics substantially. (iii) Unexpectedly, one occasional simulation outcome is a dynamically stable state of ‘tolerated intergroup theft’, raising the question if corresponding patterns also exist in real intergroup conflicts. Finally, possible implications for theories of the co-evolution of bellicosity and altruism in humans are discussed. (shrink)

The paper considers three main models of temporal consciousness proposed in grappling with the “paradox of temporal awareness”. They are based on the notion that there is a basic element of perception in the form of some “mental frame” or “apparent present” which, while effective for describing some perceptual features, does not fully reflect our phenomenal experience. It is argued that a two-level model based on the separation of the “specious present” and “current present” is best correlated with (...) higher-order theories of consciousness and should act as a basis for further development of the temporal model of consciousness.

Mipam (‘ju mi pham rgya mtsho, 1846–1912), an architect of the Nyingma (rnying ma) tradition of Tibet in the late nineteenth and early twentieth centuries, articulates two distinct models of the two truths that are respectively reflected in Madhyamaka and Yogācāra Buddhist traditions. The way he positions these two models sheds light on how levels of description are at play in his integration of these traditions. Mipam positions one kind of two-truth model as the product of an ontological (...) analysis while another model can be seen as resulting from a phenomenological reduction. He accommodates both models into his systematic interpretation, and for him, each one has an important role to play in coming to understand the nature of the Buddhist truths of emptiness and Buddha-nature. Since each model reflects a different style of analysis, or a different perspective on truth, his presentation reveals how neither model alone has the last word on the nature of what is and how it is experienced. This paper analyzes the means by which he lays out these two models of the two truths, and explores the implications of their integration in his philosophical works. A primary concern for Mipam, and a factor that guides his attempt to integrate these two approaches to truth, is his aim to both induce authentic experience and true knowledge on the one hand, and represent reality and the experience of it on the other. These competing and complimentary objectives are a central focus around which both styles of critical reflection, and both models of the two truths, revolve. (shrink)

Predictions about the health risks of low level radiation combine two sorts of measures. One estimates the amount and kinds of radiation released into the environment, and the other estimates the adverse health effects. A new field called health physics integrates and applies nuclear physics to cytology to supply both these estimates. It does so by first determining the kinds of effects different types of radiation produce in biological organisms, and second, by monitoring the extent of these effects produced (...) by given levels of exposure. This essay examines the interplay between evidential constraints and external, contextual interests and values in studying the biological hazards of radiation. By analyzing the debate over linear vs. quadratic dose response models, the essay focuses on problems of developing quantitative, rather than qualitative, estimates of the risks of increased cancer incidence in an exposed population.

Preference is a key area where analytic philosophy meets philosophical logic. I start with two related issues: reasons for preference, and changes in preference, first mentioned in von Wright’s book The Logic of Preference but not thoroughly explored there. I show how these two issues can be handled together in one dynamic logical framework, working with structured two-level models, and I investigate the resulting dynamics of reason-based preference in some detail. Next, I study the foundational issue of entanglement (...) between preference and beliefs, and relate the resulting richer logics to belief revision theory and decision theory. (shrink)

'Mass terms', words like water, rice and traffic, have proved very difficult to accommodate in any theory of meaning since, unlike count nouns such as house or dog, they cannot be viewed as part of a logical set and differ in their grammatical properties. In this study, motivated by the need to design a computer program for understanding natural language utterances incorporating mass terms, Harry Bunt provides a thorough analysis of the problem and offers an original and detailed solution. An (...) extension of classical set theory, Ensemble Theory, is defined, and this provides the conceptual basis of a framework for the analysis of natural language meaning which Dr Bunt calls Two-level model-theoretic semantics. The validity of the framework is convincingly demonstrated by the formal analysis of a fragment of English including sentences with quantified and modified mass terms. Separate chapters of the book are devoted to an axiomatic definition of Ensemble Theory and a detailed discussion of its status as a mathematical formalism. (shrink)

The notion of intersubjectivity has achieved a primary status in contemporary psychoanalytic debate, stimulating new theoretical proposals as well as controversies. This paper presents an overview of the main contributions on inter-subjectivity in the field of neurosciences. In humans as well as—probably—in other species, the ability for emotional resonance is guaranteed early in development. Based on this capacity, a primary sense of connectedness is established that can be defined inter-subjective in that it entails sharing affective states and intentions with caregivers. (...) We propose to define such a form of inter-subjectivity ascontingent, since the infant’s early abilities for resonance do not imply the more generalized capacity to permanently conceive of the relationship outside the realm of current interactions and the infant-caregiver’s mutual correspondence of internal states. This form of connection, hence, results in a self-referential, bodily, and affectively codified, context- and time dependent, like-me experience of interactions. The gradual maturation of brain structures and processes as well as interactive experiences allow proper intersubjectivity exchanges, grounded on new intentional and representational capacities, to evolve. In this more mature form of intersubjectivity, the individual is allowed to conceive of her own psychic space both as distinct and as possibly connected with the other’s contents and experience, even in the absence of current behavioral indicators of such correspondence. This multi-layered model of intersubjectivity, which is embraced by current neuroscience research, seems to allow for new interpretations of psychoanalytic models of human relatedness based upon classic clinical observations.

The article revisits two basic questions of political theory posed by Jon Elster. First, should the political process be defined as private or public, and second, should its purpose be understood instrumentally or intrinsically? Having posed these questions, Elster arrives at three views of politics: social choice , republican and discourse theory . I argue for a fourth view , and explain Elster's omission of this model by referring to his underlying paradigm of politics, that is, as will formation. The (...) main thesis in Elster's article is about whether the process of will formation should be relegated to the market mechanism or dealt with via deliberative forums. I reject this paradigm and argue instead for politics as jurisdiction. This notion of politics is concerned with the question of how both market and forum processes of will formation should be institutionalized. Defining politics as jurisdiction strongly improves the plausibility of the missing fourth model of democratic will formation, as a depiction of democratic will formation as private in its process and intrinsic in its purpose illustrates the importance of distinguishing between two levels of democracy: namely, the civil level of will formation and the political level of jurisdiction.

A key challenge for probabilistic causal models is to distinguish non-causal probabilistic dependencies from true causal relations. To accomplish this task, causal models are usually required to satisfy several constraints. Two prominent constraints are the causal Markov condition and the faithfulness condition. However, other constraints are also needed. One of these additional constraints is the causal sufficiency condition, which states that models must not omit any direct common causes of the variables they contain. In this paper, I (...) argue that the causal sufficiency condition is problematic: (1) it is incompatible with the requirement that the variables in a model must not stand in non-causal necessary dependence relations, such as mathematical or conceptual relations, or relations described in terms of supervenience or grounding, (2) it presupposes more causal knowledge as primitive than is actually needed to create adequate causal models, and (3) if models are only required to be causally sufficient, they cannot deal with cases where variables are probabilistically related by accident, such as Sober’s example of the relationship between bread prices in England and the sea level in Venice. I show that these problems can be avoided if causal models are required to be monotonic in the following sense: the causal relations occurring in a model M would not disappear if further variables were added to M. I give a definition of this monotonicity condition and conclude that causal models should be required to be monotonic rather than causally sufficient. (shrink)

Sustainable development is an everlasting theme and lasting strategy in today’s era. Low-carbon economy is an inevitable approach to the implementation of sustainable development. Cold chain logistics has become one of the main sources of carbon emissions. However, in the research on location planning of cold chain logistics, the costs of carbon emissions have not been taken into consideration in previous studies. The two-stage stochastic optimization model was established based on the comprehensive consideration of transportation costs, time penalty costs, and (...) carbon emission costs. In this case, it is extremely difficult to deal with uncertainty in TSSO model. Therefore, this paper constructs a two-stage robust optimization model using data-driven method and robust optimization theory and verifies the validity of this model through an actual case. The application of this method to a cold chain logistics enterprise showed that the service level of logistics cannot be guaranteed by stochastic optimization model. In the TSRO model, the costs increase by 2.18% at the price of robustness, whereas logistics service level shows an upward trend. In the TSRO model, enterprises are forced to choose a better distribution path when carbon tax increases, which not only helps enterprises save costs but also achieves low-carbon environmental benefits.

Increasing farmers’ acceptance and adoption of environmentally beneficial farming practices is essential for mitigating negative impacts of agriculture. To support adoption through policy, it is necessary to understand which types of farms or farmers do or do not apply such practices. However, farmers are not a homogeneous group and their behavior is subject to a complex array of structural, socioeconomic, and socio-psychological influences. Reducing this complexity, farmer typologies or archetypes are useful tools for understanding differing motivations for the uptake of (...) sustainable farming practices. Previous investigations of the role of farmer archetypes in the adoption of such practices rely on either purely qualitative or purely quantitative methods in data collection, typology creation, and hypothesis testing. Our study combines both approaches by classifying survey respondents into farmer types based on a previous Q methodological study. We then use these types in a two-part regression model that aims to explain participation in agri-environmental schemes and the level of scheme participation. To control for farm structural factors, we additionally link our questionnaire data to secondary data from the farm accountancy data network. Results indicate that in Austria, AES are attractive to all types of farmers, but the level of participation in these schemes differs between archetypes: Profitability-oriented farmers participate less, and nature-oriented farmers participate more than other types. This suggests that monetary compensations for sustainable farming practices are not perceived as sufficient by certain groups of farmers, and policy makers need to consider additional kinds of incentives.

According to the two visual systems model, the visual processing of objects divides into semantic and pragmatic processing. We provide various criteria for this distinction. Further, we argue that both the semantic and pragmatic processing of visual information about objects should be divided into low-level processing and high-level processing. Finally, we re-evaluate the contribution of the human parietal lobe to the concious visual perception of spatial relations among objects.

Ethics involves an organized, reasoned approach to gathering and processing data in order to arrive at decisions about what to do, what to value, and/or what virtues to cultivate. A model is proposed for conceptualizing this complex dynamic, which incorporates elements of both rule-and-principle ethics and the ethic of care. The model suggested here has two levels. The first level identifies the components that comprise philosophical reasoning; the second contextualizes and operationalizes the model in relation to the processor’s philosophical (...) stance on the nature of knowing. Three philosophical stances are identified and described: science-dominant, person-dominant, and science-person equilibrium. Physicians tend to process patients from first perspectives, nurses from second. Hence, health team collaboration in moral problem solving is critically important. (shrink)

In this essay, it is argued that naturalism of an even moderate sort speaks strongly against a certain widely held thesis about the human mental (and cognitive) architecture: that it is divided into two distinct levels, the personal and the subpersonal, about the former of which we gain knowledge in a manner that effectively insulates such knowledge from the results of scientific research. -/- An empirically motivated alternative is proposed, according to which the architecture is, so to speak, flattened from (...) above. On this flattened view, although the states and processes typically associated with the personal level likely appear in our best models of the production of human behavior, they appear alongside states and processes normally associated with the subpersonal level. Moreover, the success of such models depends nowise on a levels-based distinction between the various causal contributors. It is argued that the flattened view has methodological implications of significant import. (shrink)

This paper is a critical evaluation of Holger Thesleff’s thinking on Plato’s Forms, especially of his “rethinking” of the matter, as he puts it in the title of his most recent contribution. It lays out a broadly sympathetic perspective through dialectical engagement with the main lines of his interpretation and reconstruction of Plato’s world. The aim is to launch the formal academic reception of that reconstruction (rethinking), which Thesleff cautiously and modestly presents as a “proposal” — his teaser to elicit (...) a reaction, positive or negative. The exegetical focus is on tracing the inspiration and reasoning behind his “two-level” model of Plato’s ontology, which, in turn, supports his tripartite classification of Forms. The critical focus is on identifying potential areas of misunderstanding and supplying any explanations, analyses, or arguments that may enhance the clarity of the respective positions. (shrink)

Bayesian approaches for estimating multilevel latent variable models can be beneficial in small samples. Prior distributions can be used to overcome small sample problems, for example, when priors that increase the accuracy of estimation are chosen. This article discusses two different but not mutually exclusive approaches for specifying priors. Both approaches aim at stabilizing estimators in such a way that the Mean Squared Error of the estimator of the between-group slope will be small. In the first approach, the MSE (...) is decreased by specifying a slightly informative prior for the group-level variance of the predictor variable, whereas in the second approach, the decrease is achieved directly by using a slightly informative prior for the slope. Mathematical and graphical inspections suggest that both approaches can be effective for reducing the MSE in small samples, thus rendering them attractive in these situations. The article also discusses how these approaches can be implemented in Mplus. (shrink)
