Arguments are given against the thesis that properties and propositional functions are identical. The first shows that the familiar extensional treatment of propositional functions -- that, for all x, if f(x) = g(x), then f = g -- must be abandoned. Second, given the usual assumptions of propositional-function semantics, various propositional functions (e.g., constant functions) are shown not to be properties. Third, novel examples are given to show that, if properties were identified with propositional functions, crucial fine-grained intensional distinctions would (...) be lost. (shrink)

PurposeContinuous patient-reported outcomes to identify and address patients’ needs represent an important addition to current routine care. The aim of this study was to identify and determine important dimensions of health-related quality of life in routine oncological care.MethodsIn a cross-sectional qualitative study, interviews and focus groups were carried out and recorded. The interviewees were asked for their evaluation on HrQoL in general and specifically regarding cancer treatment. The material was transcribed and analyzed using qualitative content analysis based on Mayring. The (...) results were reviewed in an expert discussion.ResultsInterviews with patients and clinicians, as well as five focus groups with clinicians were conducted. Initially, nine deductive and two inductive categories on HrQoL were built. Four categories were excluded following the qualitative content analysis because they were hardly or not at all mentioned by participants. Following on from the analysis of the expert discussion, one dimension was added, and two further categories were excluded. The resulting system consisted of six dimensions: emotional health, physical ailments, autonomy, social functionality, dignity, and resources.ConclusionThe identified dimensions of HrQoL in routine oncological care were found to differ from those used in existing HrQoL measurements for patients. Further research is needed to test and evaluate the presented structure in a larger sample of cancer patients to further assess its psychometric properties. (shrink)

Formal learning theory constitutes an attempt to describe and explain the phenomenon of learning, in particular of language acquisition. The considerations in this domain are also applicable in philosophy of science, where it can be interpreted as a description of the process of scientific inquiry. The theory focuses on various properties of the process of hypothesis change over time. Treating conjectures as informational states, we link the process of conjecture-change to epistemic update. We reconstruct and analyze the temporal aspect of (...) learning in the context of dynamic and temporal logics of epistemic change. We first introduce the basic formal notions of learning theory and basic epistemic logic. We provide a translation of the components of learning scenarios into the domain of epistemic logic. Then, we propose a characterization of finite identifiability in an epistemic temporal language. In the end we discuss consequences and possible extensions of our work. (shrink)

Dawson's provocative comment makes three connected points: (1) to be falsifiable, theories that assume flexible features must constrain their feature creation and mechanisms, (2) the explanatory power of such functional theories is rooted in the properties of their underlying physical mechanisms, and (3) to derive the relevant constraints of feature creation from these mechanisms, it is critical to avoid the scope slip. We will argue here that even though we agree with (1) and (2), (3) confuses two different levels of (...) analysis of computational systems: the functional identification and the physical implementation of relevant constraints.

In orthodox quantum mechanics, it has virtually become the custom to identify properties of a physical system with operationally testable propositions about the system. The causes and consequences of this practice are explored mathematically in this paper. Among other things, it is found that such an identification imposes severe constraints on the admissible states of the physical system.

This paper provides an account of co-identification with fictional names, the way in which a fictional name can be used to talk about the same fictional character on disparate occasions. I develop a version of the view that fictional characters are roles constituted by sets of properties that is couched within a dynamic understanding of fictional discourse. I argue that this view captures what is right about both so-called name-centric and information-centric approaches to co-identification with fictional names. I (...) show how the dynamic view in addition accounts for a number of uses of fictional names, including fictional uses, assertoric uses, metafictional uses. (shrink)

In this paper, I make a case for interpreting the Lysis as a dialogue of definition, designed to answer the question of “What is a friend?” The main innovation of my interpretation is the contention – and this is argued for in the paper – that Socrates hints towards a definition of being a friend that applies equally to mutual friendship and one-way attraction – the two kinds of friend relation very clearly identified by Socrates in the dialogue. The key (...) to understanding how the two different kinds of friendship can have a common definition is to appreciate that the property of being a friend has a relational character. (shrink)

The principle of relativity, that there is no preferred state of uniform motion, has recently come into conflict with certain cosmological observations. In an attempt to overcome this difficulty, an alternative formulation is explored in which this principle is replaced by the principle of universal time, while retaining the invariance of the speed of light. These two postulates lead to a well-defined world model in which one inertial frame has a preferred status. But the invariance properties of the laws of (...) physics are unaffected, and the model may be regarded as a modified form of special relativity which is in accordance with the new cosmological evidence.

A universal property of visual word identification is position-invariant letter identification, such that the letter is coded in the same way in CAT and ACT. This should provide a fundamental constraint on theories of word identification, and, indeed, it inspired some of the theories that Frost has criticized. I show how the spatial coding scheme of Colin Davis can, in principle, account for contrasting transposed letter priming effects, and at the same time, position-invariant letter identification.

I attempt to rebut Dean Zimmerman's novel argument (2010), which he presents in support of substance dualism, for the conclusion that, in spite of its popularity, the combination of property dualism with substance materialism represents a precarious position in the philosophy of mind. I take issue with Zimmerman's contention that the vagueness of ‘garden variety’ material objects such as brains or bodies makes them unsuitable candidates for the possession of phenomenal properties. I also argue that the ‘speculative materialism’ that (...) is available to a substance materialist property dualist who abandons the identification of persons with such garden variety objects is significantly more attractive than Zimmerman allows. Although I do not attempt to refute its substance dualist rival, I conclude that the combination of property dualism with substance materialism can withstand Zimmerman's objections. (shrink)

In a previous Philo article, it was shown how properties could be ontologically dispensed with via a representational analysis: to be an X is to comprehensively represent all the properties of an X. The current paper extends that representationalist (RT) theory by explaining representation itself in parallel epistemic rather than ontological terms. On this extended RT (ERT) theory, representations of X, as well as the real X, both may be identified as providing information about X, whether partial or comprehensive. But (...) that information does not match ontological, property-based analyses of X, so it is epistemically fundamental–hence supporting a broadly conceptualist rather than nominalist metaphysics.

Many characterizations of definiteness in natural language have been given. However a number of them converge on a single idea involving uniqueness of applicability of a property. This paper will attempt to do two things. One is to try to unify some of these current views of definiteness, seeing them as drawing out Gricean conversational implicatures of the uniqueness concept, and the other is to try a more articulated approach to dealing with some recalcitrant counterexamples. I will focus primarily, (...) but not entirely, on definite descriptions in English. (shrink)

Objective: This study aimed to test the psychometric properties of the suicide stroop task in a Chinese college population. Methods: College students who were in the 1st–4th grade, fluent in Chinese, and without color blindness were recruited from a university in Guangzhou, China from September to December 2019. Participants were administered the suicide stroop task at baseline and 1-month follow-up. Results: The suicide stroop task showed excellent internal reliability. However, the suicide stroop task did not reveal suicide-related attentional biases among (...) current suicide ideators and was not significantly associated with the severity of suicidal ideation, depression, hopelessness, nor anhedonia, indicating a lack of concurrent validity for the task. Additionally, the two-time data of interference scores could not generate intraclass correlation coefficients due to a negative average covariance among data, which indicated poor test–retest consistency for the task. Conclusion: The results of this study did not support the use of the suicide stroop task on the identification of suicidal risk among Chinese college students. It is crucial to assess the psychometric properties of behavioral measures rigorously as self-report measures before large applications in clinical and community settings. (shrink)

The so-called ‘re-identification condition’ (Kelly 2011) has played an important role in the most prominent argument for nonconceptualism, the argument from fineness of grain. A number of authors have recently argued that the condition should be modified or discarded altogether, with devastating implications for the nonconceptualist (see, e.g., Brewer 2005, Chuard 2006). The aim of this paper is to show that the situation is even more dire for nonconceptualists, for even if the re-identification condition remains in its original (...) form, the argument from fineness of grain still fails to make the case for nonconceptualism. The paper's central case rests on two claims: according to the first, if the re-identification condition holds, then some beliefs will represent some properties nonconceptually; and according to the second, if some beliefs represent some properties nonconceptually, the argument from fineness of grain fails to make the case for nonconceptualism in any relevant sense. It follows that if the re-identification condition holds, the argument from fineness of grain fails to make the case for nonconceptualism. (shrink)

Noneism a is form of Meinongianism, proposed by Richard Routley and developed and improved by Graham Priest in his widely discussed book Towards Non-Being. Priest's noneism is based upon the double move of building a worlds semantics including impossible worlds, besides possible ones, and admitting a new comprehension principle for objects, differerent from the ones proposed in other kinds of neo-Meinongian theories, such as Parsons' and Zalta's. The new principle has no restrictions on the sets of properties that can deliver (...) objects, but parameterizes the having of properties by objects to worlds. Modality is therefore explicitly built in - so the approach can be conveniently labeled as "modal noneism". In this paper, I put modal noneism to work by testing it against classical issues in modal logic and semantics. It turns out that - perhaps surprisingly - the theory performs well in problems of transworld identity, which are frequently considered to be the difficult ones in the literature; faces a limitation, albeit not a severe one, when one comes to transworld individuation, which is often taken as an easy issue, if not a pseudo-problem; and may stumble upon a real trouble when dealing with what I shall call 'extensionally indiscernible entities' - particular nonexistent objects modal noneism is committed to.

Roderick Chisholm has proposed a novel theory of reference and belief involving the undefined notion of directly attributing a property. He uses direct attribution to account for Castañeda’s “he, himself” puzzle and for beliefs de re. He affirms as an axiom of his theory principle P1: if x directly attributes z to y, then x is identical to y. I shall argue that principle P1 is defective in that it prevents the identification of x with y and thus (...) renders Chisholm’s theory incapable of expressing a wide range of psychological phenomena. Thus the theory is an inadequate model of psychological reality. (shrink)

This essay focuses on an issue arising from within an anti-essentialist perspective on sexual identity: how is it possible to explain the political impetus inhering in a category such as 'woman' without having recourse to a set of positive properties that would somehow fix her identity in advance? I examine how a particular theoretical outlook, social postmodernism, attempts to address this issue, and argue that, ultimately, social postmodernism generates its own impasse which I call social foundationalism - an impasse which (...) is structurally similar to biological foundationalism. I invoke discourse -theoretic concepts to introduce the psychoanalytic categories of master signifier and symbolic identification. This is done in order to suggest how Lacanian psychoanalysis permits us to theorize sexual difference in a way that avoids both biological foundationalism and social foundationalism. Key Words: discourse theory • identification • identity • Lacan • poststructuralism • psychoanalysis • sexual difference • social postmodernism. (shrink)

Kim has defended a solution to the exclusion problem which deploys the «causal inheritance principle» and the identification of instantiations of mental properties with instantiations of their realizing physical properties. I wish to argue that Kim's putative solution to the exclusion problem rests on an equivocation between instantiations of properties as bearers of properties and instantiations as property instances. On the former understanding, the causal inheritance principle is too weak to confer causal efficacy upon mental properties. And on (...) the latter understanding, the identification of mental and physical instantiations is simply untenable. (shrink)

Kripke observes that the decimal numerals have the buck-stopping property: when a number is given in decimal notation, there is no further question of what number it is. What makes them special in this way? According to Kripke, it is because of structural revelation: each decimal numeral represents the structure of the corresponding number. Though insightful, I argue, this account has some counterintuitive consequences. Then I sketch an alternative account of the buck-stopping property in terms of how we (...) specify the positions of numbers in the progression. (shrink)

According to a prominent line of thought, we can be physicalists, but not reductive physicalists, by holding that mental and other ‘higher-level’ or ‘nonbasic’ properties — properties that are not obviously physical properties — are all physically realized. Spelling this out requires an account of realization, an account of what it is for one property to realize another. And while several accounts of realization have been advanced in recent years,1 my interest here is in the ‘subset view,’ which has (...) often been invoked explicitly in defense of nonreductive physicalist positions.2 The subset view holds that property realization consists in the powers of one property having as a subset the powers of another; ..

This paper addresses a famous objection against David Lewis’s Best System Analysis (BSA) of laws of nature. The objection—anticipated and discussed by Lewis (1994)—focuses on the standards of simplicity and strength being (in part) a matter of psychology. Lewis’s answer to the objection relies on his metaphysics of natural properties and its ability to single out the robustly best system, a system that is expected to come out far ahead of its rivals under any standard of simplicity and strength. The (...) main task of this paper is to argue that Lewis’s reply to the objection in terms of nature being kind to us does not succeed, if nature’s kindness is understood in terms of the naturalness of the properties composing the Humean mosaic. For epistemic access to natural properties is downstream to any previous identification of the best system. A possible Lewisian rejoinder in terms of a cross-world Humean mosaic of natural properties is considered and rebutted. The paper concludes by suggesting that Lewis could instead avail himself of a better answer to the objection, if the standards of simplicity and strength were reinterpreted along perspectivalist lines.

Observability is a modelling property that describes the possibility of inferring the internal state of a system from observations of its output. A related property, structural identifiability, refers to the theoretical possibility of determining the parameter values from the output. In fact, structural identifiability becomes a particular case of observability if the parameters are considered as constant state variables. It is possible to simultaneously analyse the observability and structural identifiability of a model using the conceptual tools of differential (...) geometry. Many complex biological processes can be described by systems of nonlinear ordinary differential equations and can therefore be analysed with this approach. The purpose of this review article is threefold: to serve as a tutorial on observability and structural identifiability of nonlinear systems, using the differential geometry approach for their analysis; to review recent advances in the field; and to identify open problems and suggest new avenues for research in this area.

In an era characterized by fast technological progress that introduces new unpredictable scenarios every day, working in the law field may appear very difficult, if not supported by the right tools. In this respect, some systems based on Artificial Intelligence methods have been proposed in the literature, to support several tasks in the legal sector. Following this line of research, in this paper we propose a novel method, called PRILJ, that identifies paragraph regularities in legal case judgments, to support legal (...) experts during the redaction of legal documents. Methodologically, PRILJ adopts a two-step approach that first groups documents into clusters, according to their semantic content, and then identifies regularities in the paragraphs for each cluster. Embedding-based methods are adopted to properly represent documents and paragraphs into a semantic numerical feature space, and an Approximated Nearest Neighbor Search method is adopted to efficiently retrieve the most similar paragraphs with respect to the paragraphs of a document under preparation. Our extensive experimental evaluation, performed on a real-world dataset provided by EUR-Lex, proves the effectiveness and the efficiency of the proposed method. In particular, its ability of modeling different topics of legal documents, as well as of capturing the semantics of the textual content, appear very beneficial for the considered task, and make PRILJ very robust to the possible presence of noise in the data.

The book offers new answers to two central questions that have been heavily debated, especially in recent years, in the debate on so-called de se skepticism: Is there something special about first-person thinking? And how does it relate to other forms of self-consciousness? The answer to the first question is a resounding "yes." This assertion is justified by the double-reflexive structure, motivational force, and specific concern that first-personal thinking involves. Regarding the second question, the book concludes that there are non-linguistic (...) forms of self-consciousness. However, these should not be understood as representational contents or non-relational properties, but as mental relations that, without themselves being represented, can contribute to the phenomenal character of conscious states. In this respect, the book also provides a justification for the rarely considered impure intentionalism. (shrink)

John goes out for a walk. If John endures and his walk perdures, they are different entities. However, what if both John and his walk perdure? Is John’s walk identical to his relevant temporal part? Some philosophers answer in the affirmative. Their motivations rest on ontological parsimony and the quest for clear-cut identity criteria for existing things. By contrast, one of the most widely accepted theories of events – the theory of events as property-exemplifications – allows us to formulate (...) an argument to the effect that objects’ temporal parts are distinct from the events they participate in: the AID argument, as I shall call it. In this paper, I argue that accepting austere nominalism is the best strategy a supporter of the identification between events and temporal parts of objects can take in order to resist the AID argument.

The Anxiety-Buffering Properties of Cultural and Subcultural Worldviews: Terror Management Processes among Juvenile Delinquents Terror management research indicates that people reminded of mortality strongly affirm values and standards consistent with their cultural worldview and distance themselves from values and standards inconsistent with it. However, limited research has addressed how individuals holding beliefs inconsistent with the dominant worldview cope with death-related anxiety. The present article aims to determine which worldview subcultural groups rely on when reminded of mortality: mainstream or subcultural? Juvenile (...) delinquents living in residential reformatories in Poland were invited to participate in a terror management study examining the anxiety-buffering strategies of individuals belonging to a group largely outside mainstream culture. Following reminders of mortality, juvenile delinquents increased support for values consistent with the mainstream cultural worldview and decreased support for values consistent with the subcultural worldview, as compared to control conditions. The present results suggest that when faced with existential threat, the subcultural worldview does not provide an adequate anxiety buffer, leading members of this subcultural group to display increased identification with mainstream cultural values. Additionally, participants' state anxiety following death reminders was mediated by mainstream cultural worldview defense. (shrink)

In this paper, I offer a conceptual framework for understanding and evaluating personal identity claims. I analyze ontological and political properties of personal identity separately, arguing that their conceptual (if not practical) separation is necessary for a proper evaluation of different identity claims.

Finally, I outline the guidelines for a justified liberal policy of recognition.

School climate is a multidimensional construct that has been related to a series of psychological, social, and school variables. The dual school climate and school identification measure-student (SCASIM-St) is a measure that has a multidimensional factor structure, with four first-order factors and a second-order factor, plus an independent factor that evaluates school identification. However, the SCASIM-St is long, with 38 items measuring school climate. The first objective of this study was to examine the psychometric properties of reliability and (...) validity of the abbreviated version of the dual school climate and school identification measure-student (SCASIM-St-15), for use in contexts with time limitations or for explanatory studies that need to apply multiple instruments simultaneously. The second objective was to analyze the degree of invariance for the groups: sex, type of education, and age. The sample was made up of 2,044 students of both sexes (49.1% women and 50.9% men), with a mean age of 14.64 (SD = 0.718), representing 27 secondary schools in Chile. The results indicated that the SCASIM-St15 presents adequate indicators of reliability and construct validity. Evidence of external criterion validity confirmed significant associations with the Attitudes to Institutional Authority in Adolescence Scale measure. The results of the factorial invariance analysis indicate that the SCASIM-St15 remains stable up to the level of metric invariance for the variable sex and the level of scalar invariance for the variables type of education and age. The study concluded that despite the significant decrease in the number of items, the SCASIM-St15 measures school climate in a reliable and valid way, without losing its theoretical and conceptual robustness.

Although perceptual grouping has been widely studied, its mechanisms remain poorly understood. We propose a neural model of grouping that, through top-down control of its circuits, implements a grouping strategy involving both a connection strategy (which elements to connect) and a selection strategy (that defines spatiotemporal properties of a selection signal to segment target elements and facilitate identification). We apply the model to a letter discrimination task that investigated relationships among uniform connectedness and the grouping principles of proximity and (...) shape similarity. Participants reported whether small circles formed a global letter E or H, and these circles could be connected by a line or be embedded in a matrix of squares. In the model, a good grouping strategy for this task consists of a connection strategy that connects circles but not squares for all conditions and a selection strategy that uses a selection signal of varying size, depending on whether squares were present. Consistent with empirical results, which were verified in two replication studies, model performance is worse with distractor squares, and line connectors improve performance only in the condition with squares. Rather than relying on abstract grouping principles, we show how the empirical results can be explained in terms of observers implementing a task-dependent grouping strategy that promotes overall performance.

According to one popular criterion of property identity, where X and Y are properties, X is identical with Y if and only if X and Y bestow the same conditional powers on their bearers. In this paper, I argue that this causal criterion of property identity is unsatisfactory, because it fails to provide a sufficient condition for the identification of properties. My argument for this claim is based on the observation that the summing of properties does not (...) entail the summing of the conditional powers that they bestow on an object, but, rather, in some cases their subtraction. If so, the following causal structure seems possible: There are two properties, A and B. Each bestows a different set of conditional powers on its bearer, but the conjunctive property A-and-B bestows exactly the same set of conditional powers as either A or B. If this causal structure is possible, then it creates a serious problem for the causal criterion of property identity. (shrink)

Im this paper I argue that Rawls distinguishes two different ways in which a system can be inconsistent with justice as fairness.

Following Esping-Andersen’s identification of different “worlds” (...) of welfare states, I will show which specific kind of welfare state falls under Rawls’s first argument. (shrink)

“Aesthetic valuism” maintains that aesthetic properties harbor an ineliminable evaluative component, and that to correctly and sincerely apply an aesthetic predicate to a thing just is to give an appraisal of its aesthetic goodness or badness. Anti-valuism denies this, and holds that even in the identification and ascription of evaluatively-loaded aesthetic properties, such as beautiful or graceful, we may identify a non-evaluative, purely descriptive, and patently aesthetic form of judgment or discrimination. In this essay, I formulate a new definition (...) of aesthetic properties that is consistent with anti-valuism, in order to see how well it serves us, in comparison with a valuist definition that appears in the published philosophical literature. If my definition is at least as intuitively plausible as the valuist’s, it should be preferred. This is because the most complicated concept my definition asks you to understand is perceptual resemblance . Value is harder to understand, and we don’t make it very easy on ourselves if we use one mystery to define another . I end by reflecting on how my definition fits into wider aesthetic concerns.

In educational and clinical settings, few norm-referenced tests have been utilized until now usually focusing on a single or a few language subcomponents, along with very few language rating scales for parents and educators. The need for a comprehensive language assessment tool for preschool and early school years children which could form the basis for valid and reliable screening and diagnostic decisions, led to the development of a new norm-referenced digital tool called Logometro®. The aim of the present study is (...) to describe Logometro® as well as its psychometric characteristics. Logometro® evaluates an array of oral language skills across the different language domains such as phonological awareness, listening comprehension, vocabulary knowledge, narrative speech, morphological awareness, pragmatics, as well emergent literacy skills in Greek-speaking 4–7 years old children. More specifically, Logometro® has been designed in order to: map individual language development paths as well as difficulties, provide a descriptive profile of children’s oral language and emergent literacy skills, and assist in the identification of children who are at risk for Developmental Language Disorder or Specific Learning Disabilities. The sample consisted of 926 children aged from 4 to 7 years, which were recruited from diverse geographical provinces and represented a variety of socioeconomic backgrounds in Greece. Eight hundred participants were typically developing children, 126 children represented children with Special Educational Needs, and 126 children were typically developing peers matched for gender and age with the clinical groups. The administration lasted 90 min, depending on the participant’s age and competence. Validity as well as internal consistency and test–retest reliability were assessed. Results indicated that Logometro® is characterized by good psychometric properties and can constitute a norm-referenced battery of oral language and emergent literacy skills. It could be used to inform the professionals as well as the researchers about a child’s language strengths and weaknesses and form the basis on which they can design an appropriate individualized intervention if needed.

We have developed a first generation tool for the unbiased identification and characterization of human pluripotent stem cells, termed PluriTest. This assay utilizes all the information contained on a microarray and abandons the conventional stem cell marker concept. Stem cells are defined by the ability to replenish themselves and to differentiate into more mature cell types. As differentiation potential is a property that cannot be directly proven in the stem cell state, biologists have to rely on correlative measurements (...) in stem cells associated with differentiation potential. Unfortunately, most, if not all, of those markers are only valid within narrow limits of specific experimental systems. Microarray technologies and recently next‐generation sequencing have revolutionized how cellular phenotypes can be characterized on a systems‐wide level. Here we discuss the challenges PluriTest and similar global assays need to address to fulfill their enormous potential for industrial, diagnostic and therapeutic applications. (shrink)

Malware is a sophisticated, malicious, and sometimes unidentifiable application on the network. The classifying network traffic method using machine learning shows to perform well in detecting malware. In the literature, it is reported that this good performance can depend on a reduced set of network features. This study presents an empirical evaluation of two statistical methods of reduction and selection of features in an Android network traffic dataset using six supervised algorithms: Naïve Bayes, support vector machine, multilayer perceptron neural network, (...) decision tree, random forest, and K-nearest neighbors. The principal component analysis and logistic regression methods with p value were applied to select the most representative features related to the time properties of flows and features of bidirectional packets. The selected features were used to train the algorithms using binary and multiclass classification. For performance evaluation and comparison metrics, precision, recall, F-measure, accuracy, and area under the curve were used. The empirical results show that random forest obtains an average accuracy of 96% and an AUC-ROC of 0.98 in binary classification. For the case of multiclass classification, again random forest achieves an average accuracy of 87% and an AUC-ROC over 95%, exhibiting better performance than the other machine learning algorithms. In both experiments, the 13 most representative features of a mixed set of flow time properties and bidirectional network packets selected by LR were used. In the case of the other five classifiers, their results in terms of precision, recall, and accuracy, are competitive with those obtained in related works, which used a greater number of input features. Therefore, it is empirically evidenced that the proposed method for the selection of features, based on statistical techniques of reduction and extraction of attributes, allows improving the identification performance of malware traffic, discriminating it from the benign traffic of Android applications.

In a Common Law system, legal practitioners need frequent access to prior case documents that discuss relevant legal issues. Case documents are generally very lengthy, containing complex sentence structures, and reading them fully is a strenuous task even for legal practitioners. Having a concise overview of these documents can relieve legal practitioners from the task of reading the complete case statements. Legal catchphrases are (multi-word) phrases that provide a concise overview of the contents of a case document, and automated generation (...) of catchphrases is a challenging problem in legal analytics. In this paper, we propose a novel supervised neural sequence tagging model for the extraction of catchphrases from legal case documents. Specifically, we show that incorporating document-specific information along with a sequence tagging model can enhance the performance of catchphrase extraction. We perform experiments over a set of Indian Supreme Court case documents, for which the gold-standard catchphrases (annotated by legal practitioners) are obtained from a popular legal information system. The performance of our proposed method is compared with that of several existing supervised and unsupervised methods, and our proposed method is empirically shown to be superior to all baselines.

Fichte's definitions of property appear to diverge from modern common linguistic usage, especially his identification of leisure as the object of an absolute right of property, and they may even appear arbitrary.

In the case of (...) Fichte's theory of property, this content turns out to be leisure as the primary object of a theory of distributive justice. The conceptual innovation found in Fichte's theory of property invites a reconceptualization of the relation between work and freedom. (shrink)

Namely, COT provides a novel conceptual landscape plenty of analytic tools to explore the interplay between structure and stability of ecological systems. Given a large set of species and their interactions, COT identifies, in a computationally feasible way, each and every sub-collection of species that is closed and self-maintaining. These sub-collections, (...) called organizations, correspond to the groups of species that can survive together in the long-term. Thus, the set of organizations contains all the stable regimes that can possibly happen in the dynamics of the ecological system. From here, we propose to conceive the notion of stability from the properties of the organizations, and thus apply the vast knowledge on the stability of reaction networks to the complexity–stability debate. As an example of the potential of COT to introduce new mathematical tools, we show that the set of organizations can be equipped with suitable joint and meet operators, and that for certain ecological systems the organizational structure is a non-boolean lattice, providing in this way an unexpected connection between logico-algebraic structures, popular in the foundations of quantum theory, and ecology.

From here, we propose to conceive the notion of stability from the properties of the organizations, and thus apply the vast knowledge on the stability of reaction networks to the complexity–stability debate. As an example of the potential of COT to introduce new mathematical tools, we show that the set of organizations can be equipped with suitable joint and meet operators, and that for certain ecological systems the organizational structure is a non-boolean lattice, providing in this way an unexpected connection between logico-algebraic structures, popular in the foundations of quantum theory, and ecology.

A uniform analysis is offered for the source of the locations specified by all references in English to spatial properties including location and movement. This source is argued to be the location of events and states of affairs. These locations are specified by sets showing spaces momentarily occupied. Descriptions of motion are accounted for through a variety of ways of referencing these sets. Some classes of simple clauses are identified as requiring semantic analysis involving multiple events and states of affairs. (...) This importantly allows spatial references to be associated with different events and states of affairs. Identification of object location is accounted for by use of extra inference rules or meaning postulates. A number of other explanations are suggested for more limited and derivative phenomena. The analysis is developed within a Case-like notation presented in the first-order predicate calculus. It is supported by an extensive analysis of spatial reference phenomena and by identification of ancillary benefits. (shrink)

Purpose – The purpose of this paper is to consider arguments both for and against intellectual property rights that are premised on each of two conceptions of the information commons that attributes either moral value or disvalue to its preservation. Design/methodology/approach – The methodology is the philosophically standard one of reflective equilibrium. The author considers the argument for a morally protected information commons that is grounded in Locke's famous proviso limiting original acquisition of material property to situations that (...) leave enough of the resource to others and Hardin's famous argument that holding material property in common leads to overuse and depletion – a Tragedy of the commons. In particular, the arguments are evaluated according to whether they cohere with ordinary foundational commitments. Findings – The author argues that neither conception of the commons is directly applicable to information objects and hence is relevant with respect to the issue of whether legal protection of IP rights is morally justified. Originality/value – The identification of key differences between material objects and information objects that shows the irrelevance of these two leading conceptions in resolving the general issue of whether legal protection of IP rights is justified.
