The article describes the nature of a faceted classification, and its application in document retrieval. The kinds of facet used are illustrated. Procedures are then discussed for identifying facets in a subject field, populating the facets with individual subject terms, arranging these in helpful sequences, using the scheme to classify documents, and searching the resultant classified index, with particular reference to Internet search.

Faceted knowledge organization systems have sophisticated logical structures, making their representation as linked data a demanding task. The term facet is often used in ambiguous ways: while in thesauri facets only work as semantic categories, in classification schemes they also have syntactic functions. The need to convert the Integrative Levels Classification (ILC) into SKOS stimulated a more general analysis of the different kinds of syntactic facets, as can be represented in terms of RDF properties and their respective domain and (...) range. A nomenclature is proposed, distinguishing between common facets, which can be appended to any class, that is, have an unrestricted domain; and special facets, which are exclusive to some class, that is, have a restricted domain. In both cases, foci can be taken from any other class (unrestricted range: free facets), or only from subclasses of an existing class (parallel facets), or be defined specifically for the present class (bound facets). Examples are given of such cases in ILC and in the Dewey Decimal Classification (DDC). (shrink)

The paper discusses issues related to the use of faceted classifications in an online environment. The author argues that knowledge organization systems can be fully utilized in information retrieval only if they are exposed and made available for machine processing. The experience with classification automation to date may be used to speed up and ease the conversion of existing faceted schemes or the creation of management tools for new systems. The author suggests that it is possible to agree (...) on a set of functional requirements for supporting faceted classifications online that are equally relevant for the maintenance of classifications, the creation of classification indexing tools, or the management of classifications in an authority file. It is suggested that a set of requirements for analytico-synthetic classifications may be put forward to improve standards for the use and exchange of knowledge organization systems. (shrink)

Facet analysis is an established methodology for building classifications and subject indexing systems, but has been less rigorously applied to thesauri. The process of creating a compatible thesaurus from the schedules of the Bliss Bibliographic Classification 2nd edition highlights the ways in which the conceptual relationships in a subject field are handled in the two types of retrieval languages. An underlying uniformity of theory is established, and the way in which software can manage the relationships is discussed. The manner of (...) displaying verbal expressions of concepts (vocabulary control) is also considered, but is found to be less well controlled in the classification than in the thesaurus. Nevertheless, there is good reason to think that facet analysis provides a sound basis for structuring a variety of knowledge organization tools. (shrink)

The basic elements of faceted thesauri are described, together with a review of their origins and some prominent examples. Their use in browsing and searching applications is discussed. Faceted thesauri are distinguished from faceted classification schemes, while acknowledging the close similarities. The paper concludes by comparing faceted thesauri and related knowledge organization systems to ontologies and discussing appropriate areas of use.

How do we think about the worlds we live in? The formation of categories of events and objects seems to be a fundamental orientation procedure. Facet theory and its main tool, the mapping sentence, deal with categories of behavior and experience, their interrelationship, and their unification as our worldviews. In this book Hackett reviews philosophical writing along with neuroscientific research and information form other disciplines to provide a context for facet theory and the qualitative developments in this approach. With a (...) variety of examples, the author proposes mapping sentences as a new way of understanding and defining complex behavior. (shrink)

Introduction into the structure, contents and specifications of the Information Coding Classification, developed in the seventies and used in many ways by the author and a few others following its publication in 1982. Its theoretical basis is explained consisting in the Integrative Level Theory, following an evolutionary approach of ontical areas, and integrating also on each level the aspects contained in the sequence of the levels, the distinction between categories of form and categories of being, the application of a feature (...) of Systems Theory and the inclusion of a concept theory, distinguishing four kinds of relationships, originated by the kinds of characteristics. Its special Subject Groups on each of its nine levels are outlined and the combinatory facilities at certain positions of the Systematifier are shown. Further elaboration and use have been suggested, be it only as a switching language between the six existing universal classification systems at present in use internationally. (shrink)

During the twentieth century, bibliographic classification theory underwent a structural revolution. The first modern bibliographic classifications were top-down systems that started at the universe of knowledge and subdivided that universe downward to minute subclasses. After the invention of faceted classification by S.R. Ranganathan, the ideal was to build bottom-up classifications that started with the universe of concepts and built upward to larger and larger faceted classes. This ideal has not been achieved, and the two kinds of classification systems (...) are not mutually exclusive. This paper examines the process by which this structural revolution was accomplished by looking at the spread of facet theory after 1924 when Ranganathan attended the School of Librarianship, London, through selected classification textbooks that were published after that date. To this end, the paper examines the role of W.C.B. Sayers as a teacher and author of three editions of The Manual of Classification for Librarians and Bibliographers. Sayers influenced both Ranganathan and the various members of the Classification Research Group (CRG) who were his students. Further, the paper contrasts the methods of evaluating classification systems that arose between Sayers’s Canons of Classification in 1915–1916 and J. Mills’s A Modern Outline of Library Classification in 1960 in order to demonstrate the speed with which one kind of classificatory structure was overtaken by another. (shrink)

Facets and general categories used in bibliographic classification have been based on a disciplinary organization of knowledge. However, facets and categories of phenomena independent from disciplines can be identified similarly. Phenomena can be classified according to a series of integrative levels (layers), which in turn can be grouped into the major strata of form, matter, life, mind, society and culture, agreeing with Nicolai Hartmann’s ontology. Unlike a layer, a stratum is not constituted of elements of the lower ones; rather, it (...) represents the formal pattern of the lower ones, like the horse hoof represents the shape of the steppe. Bibliographic categories can now be seen in the light of level theory: some categories are truly general, while others only appear at a given level, being the realization of a general category in the specific context of the level: these are the facets of that level. In the notation of the Integrative Level Classification project, categories and facets are represented by digits, and displayed in a Web interface with the help of colours. (shrink)

Introduction to a special issue on facet analysis.

The purpose of this work is to find out how different library classification systems and linguistic ontologies arrange a particular domain of interest and what are the limitations for information retrieval. We use knowledge representation techniques and languages for construction of a domain specific ontology. This ontology would help not only in problem solving, but it would demonstrate the ease with which complex queries can be handled using principles of domain ontology, thereby facilitating better information retrieval. Facet-based methodology has been (...) used for ontology formalization for quite some time. Ontology formalization involves different steps such as, Identification of the terminology, Analysis, Synthesis, Standardization and Ordering. Firstly, for purposes of conceptualization OntoUML has been used which is a well-founded and established language for Ontology driven Conceptual Modelling. Phase transformation of “the same mode” has been subsequently obtained by OWL-DL using Protégé software. The final OWL ontology contains a total of around 232 axioms. These axioms comprise 148 logical axioms, 76 declaration axioms and 43 classes. These axioms glue together classes, properties and data types as well as a constraint. Such data clustering cannot be achieved through general use of simple classification schemes. Hence it has been observed and established that domain ontology using faceted principles provide better information retrieval with enhanced precision. This ontology should be seen not only as an alternative of the existing classification system but as a Knowledge Base system which can handle complex queries well, which is the ultimate purpose of any classification system or indexing system. In this paper, we try to understand how ontology-based information retrieval systems can prove its utility as a useful tool in the field of library science with a particular focus on the education domain.

William Sharp Macleay developed the quinarian system of classification in his Horæ Entomologicæ, published in two parts in 1819 and 1821. For two decades, the quinarian system was widely discussed in Britain and influenced such naturalists as Charles Darwin, Richard Owen, and Thomas Huxley. This paper offers the first detailed account of Macleay’s development of the quinarian system. Macleay developed his system under the shaping influence of two pressures: (1) the insistence by followers of Linnaeus on developing artificial systems at (...) the expense of the natural system and (2) the apparent tension between the continuity of organic nature and the failure of linear classification schemes (which continuity seemed to require). Against what he perceived as dogmatic indolence on the part of the Linnaeans, Macleay developed a philosophy of science in which hypotheses that exceeded the available evidence should be proposed and subjected to severe tests. He also developed a novel comparative anatomical methodology, the method of variation, to aid in his search for the natural system. Using this method, he developed an intricate system that showed how organic nature could be continuous without being linear. A failure to appreciate these facets of Macleay’s thought has led to several misunderstandings of him and his work, most notably that he was an idealist. These misunderstandings are here rebutted.

Taking the idea of waste as an in-use phenomenon, we developed amatrix to explain four categories of waste which result from users’ failure touse a resource properly. These categories were illustrated by examples built onpractical food waste measurements, surveys, theses formatting requirementsand newspaper reports. We have categorized different facets of waste from abusiness perspective; thus, contributed to have improved waste managementpractices. We also showed that parsimony was also a wasteful behaviour.Parsimony was shown to be a waste by its effects on (...) others’ need of fulfilmentand other-worldly consequences for the miser. (shrink)

Evolution of cities is a subject of research for over a hundred years in the organization of urban knowledge systems. Locating five key methodological approaches used by urban scholars and practitioners, this paper demonstrates different relationships between urban studies and classification. Five significant themes form the background of urban studies literature. The first theme sources and literature explore organizing urban materials into sources and literature with a unique dimension of spatiality. The second theme discusses three important facets: scale as a (...) geographic unit of analysis and space as an abstract entity and system as a set of interdependent parts of urban places. The third theme, known as “other” urban, argued for the poor treatment of global south and how it builds inclusivity. The fourth theme, classification and retrieval, investigates the relationship between urban materials and user needs. The last theme, classification schemes, highlights subject treatment of urban in the existing library classification schemes. This paper concludes that the five themes discussed point to a model of urban studies classification. However, this model is not just concerned with urban methods, facets and formats, but explores how each theme interconnects with various sets of people-urbanists, practitioners and librarians-and through studying these actors, established boundaries of urban theories, urban librarianship and knowledge organization are crossed.

Arguments from analogy are pervasive in everyday reasoning, mathematics, philosophy, and science. Informal logic studies everyday argumentation in ordinary language. A branch of fuzzy logic, approximate reasoning, seeks to model facets of everyday reasoning with vague concepts in ill-defined situations. Ways of combining the results from these fields will be suggested by introducing a new argumentation scheme—a fuzzy analogical argument from classification—with the associated critical questions. This will be motivated by a case study of analogical reasoning in the virtual friendship (...) debate within information ethics. The virtual friendship debate is a disagreement over whether virtual friendships are genuine friendships. It will be argued that the debate could move away from its current impasse, caused by unproductive metaphysical and logical assumptions, if extant arguments are reinterpreted as fuzzy analogical arguments from classification, and subjected to a new set of critical questions which would replace the quest for facts of essence about friendship with an emphasis on empirical data, persuasion, and definitional power.

This article critiques how the chromosomal condition ‘trisomy 21’ (‘T21’) (‘Down syndrome’) was originally conceptualised using colonial, scientific and medical discourses on ‘race’ and ‘idiocy’. Nineteenth century discourses surrounding ‘degeneracy’ commonly intertwined the notions of ‘race’ and ‘idiocy’. In Observations of an Ethnic Classification of Idiots, Down categorises people with T21 as ‘Mongolians’ because of their purported similarities to ethnic ‘Mongolians’. The discourse-historical approach (DHA) to critical discourse analysis (CDA) is used in this article to examine how the ‘Mongolian idiot’ (...) is constructed by Down as the ‘other’, being simultaneously a ‘racial other’, a ‘disabled other’, and an ‘idiotic other’. Down theorises that ethnic ‘Caucasians’ with ‘idiocy’ have ‘retrogressed’ to primitive forms as characterised by the ‘Mongolian family’. His report also essentialises the ‘Mongolian idiot’, defining their ‘degeneracy’ and ‘otherness’ in terms of their physical, behavioural, and mental characteristics. Whilst Down’s ‘mongolism’ has since been refuted, aspects of his report are reproduced in some contemporary medical and scientific discourses. Although these discourses are less essentialist than Down’s, they persist in constructing the ‘otherness’ of T21, by foregrounding its ‘abnormalities’ and ‘disorders’. Significantly, facets of ‘degeneracy’ appear in evolutionary developmental biology, connecting T21 with ‘atavisms’, though without the racial framework. (shrink)

We show how faceted search using a combination of traditional classification systems and mixed-membership topic models can go beyond keyword search to inform resource discovery, hypothesis formulation, and argument extraction for interdisciplinary research. Our test domain is the history and philosophy of scientific work on animal mind and cognition. The methods can be generalized to other research areas and ultimately support a system for semi-automatic identification of argument structures. We provide a case study for the application of the methods (...) to the problem of identifying and extracting arguments about anthropomorphism during a critical period in the development of comparative psychology. We show how a combination of classification systems and mixed-membership models trained over large digital libraries can inform resource discovery in this domain. Through a novel approach of “drill-down” topic modeling—simultaneously reducing both the size of the corpus and the unit of analysis—we are able to reduce a large collection of fulltext volumes to a much smaller set of pages within six focal volumes containing arguments of interest to historians and philosophers of comparative psychology. The volumes identified in this way did not appear among the first ten results of the keyword search in the HathiTrust digital library and the pages bear the kind of “close reading” needed to generate original interpretations that is the heart of scholarly work in the humanities. Zooming back out, we provide a way to place the books onto a map of science originally constructed from very different data and for different purposes. The multilevel approach advances understanding of the intellectual and societal contexts in which writings are interpreted. (shrink)

This article reviews existing approaches to defining and distinguishing communication styles and proposes a common frame of reference for future research. The literature review yields two schools of thought: the behavior-centered perspective and the personality-oriented perspective. Although these lines of research differ in their ways of defining communication styles, they show considerable similarities with respect to their classification. Many researchers build their taxonomies on two key dimensions: assertiveness and responsiveness. We propose embedding communication styles into the Five-Factor Theory and defining (...) them as characteristic adaptations of personality. We also suggest the Interpersonal Circumplex as a reference model for distinguishing communication styles as it is able to integrate substantial dimensions and facets of existing taxonomies in a parsimonious way.

Social science, history, and philosophy have often been neglect in thinking through their fundamentally intertwined relationship. The result is often an inattention to philosophy where social science and history is concerned, or a neglect of historicity and social analysis where philosophy is concerned. Meanwhile, the place of values in research is often uneasily passed over in silence. The inattention to, and loss of, the intersection between these different disciplines and their subject matters, leaves our investigations all the more impoverished as (...) a result. In resolving these problems, it is not enough to strive for cooperation or integration, but to rethink of the nature of the disciplines themselves; their interests, purposes, and presuppositions. In this volume, contributors explore different facets of these relationships, and move beyond the problematics erected by positivism often cast in terms of value-free or value-neutral science, that is, a science obsessed with empirical data, schematic classifications, and the pursuit of law-like forms. While positivism has been subject to critique, the influence and legacy of positivism remains. It remains in the way in which we often think about science; the line drawn between the sciences and the humanities; the norms researchers should follow; what a successful explanation looks like; and the ethical, normative, and political implications of scientific research. Aimed at students and researchers of philosophy, history and the social sciences, this book is driven by a desire to revindicate questions concerning ontology and social ontology, to rethink the nature of explanation, and to resituate normativity and values within scientific, social scientific, and historical pursuits.

In this article I intend to give more attention to Pufendorf's ideas than has been the custom among international relations theorists. The main focus will be upon Pufendorf's distillation and conceptualization of the implications of Westphalia in terms of sovereignty and the integrity of states. Furthermore, his extension of the Aristotelian classification of types of state, and his attempts to go beyond Bodin's and Hobbes's theories of sovereignty, provide the vocabulary and concepts in terms of which the different international actors (...) of the late seventeenth century could be understood. In this respect the focus is altogether different from Linklater. My emphasis upon the historical and emblematic character of the Peace of Westphalia, the personification of the state and its animation by sovereignty, which serves to facilitate Pufendorf's exploration of the idea of a system of states, and my suggestion that his ideas are not wholly redundant and may be used to explore some facets of a modern states system, serve considerably to extend Forsyth's brief analysis.

Most experimental studies of facial expression processing have used static stimuli (photographs), yet facial expressions in daily life are generally dynamic. In its original photographic format, the Karolinska Directed Emotional Faces (KDEF) has been frequently utilized. In the current study, we validate a dynamic version of this database, the KDEF-dyn. To this end, we applied animation between neutral and emotional expressions (happy, sad, angry, fearful, disgusted, and surprised; 1,033-ms unfolding) to 40 KDEF models, with morphing software. Ninety-six human observers categorized (...) the expressions of the resulting 240 video-clip stimuli, and automated face analysis assessed the evidence for 6 expressions and 20 facial action units (AUs) at 31 intensities. Low-level image properties (luminance, signal-to-noise ratio, etc.) and other purely perceptual factors (e.g., size, unfolding speed) were controlled. Human recognition performance (accuracy, efficiency, and confusions) patterns were consistent with prior research using static and other dynamic expressions. Automated assessment of expressions and AUs was sensitive to intensity manipulations. Significant correlations emerged between human observers’ categorization and automated classification. The KDEF-dyn database aims to provide a balance between experimental control and ecological validity for research on emotional facial expression processing. The stimuli and the validation data are available to the scientific community. (shrink)

Background Medical assistance in dying (MAiD) sparks debate in several countries, some of which allow or plan to allow MAiD where a mental disorder is the sole underlying medical condition (MAiD-MD). Since MAiD-MD is becoming permissible in a growing number of jurisdictions, there is a need to better understand the moral concerns related to this option. Gaining a better understanding of the moral concerns at stake is a first step towards identifying ways of addressing them so that MAiD-MD can be (...) successfully introduced and implemented, where legislations allow it. Methods Thus, this article aims (1) to better understand the moral concerns regarding MAiD-MD, and (2) to identify potential solutions to promote stakeholders’ well-being. A qualitative thematic review was undertaken, which used systematic keyword-driven search and thematic analysis of content. Seventy-four publications met the inclusion criteria. Results Various moral concerns and proposed solutions were identified and are related to how MAiD-MD is introduced in 5 contexts: (1) Societal context, (2) Healthcare system, (3) Continuum of care, (4) Discussions on the option of MAiD-MD, (5) MAiD-MD practices. We propose this classification of the identified moral concerns because it helps to better understand the various facets of discomfort experienced with MAiD-MD. In so doing, it also directs the various actions to be taken to alleviate these discomforts and promote the well-being of stakeholders. Conclusion The assessment of MAiD-MD applications, which is part of the context of MAiD-MD practices, emerges as the most widespread source of concern. Addressing the moral concerns arising in the five contexts identified could help ease concerns regarding the assessment of MAiD-MD. (shrink)

The Sixteenth International Conference on Knowledge Organization was to have been held in Aalborg, Denmark in July 2020. Cancelled due to COVID-19, the proceedings were published online on 4 December 2020 containing 48 full papers, 17 short papers and 14 posters. Informetric analysis of the proceedings reveals the shifting intension and extension of the knowledge organization domain. International participation was extensive as usual. There is a much larger share of empirical and applied technical research, and therefore much less historical or (...) analytical work than before. The shape of the research front continues to revolve around concept theory and domain analysis, but cultural and ethical issues are more prevalent than before, having attained nearly core status. There is new emphasis on concepts around interdisciplinarity and phenomenon-based knowledge organization systems, and facet analytical theory has been extended into new approaches in the linked data environment. There are more journal articles than before. No monographs are highly cited but interdisciplinarity, Wittgenstein, domain analysis and music classification are prominent alongside archival science and ontology construction on the bookshelf for this conference. Among conferences ISKO and its chapters predominate. The discourse represented by the works on ISKO 16’s bookshelf seems to be rooted in classical concept theory. There is some concretization of discourse concerning interoperability and the continued distancing from ideas of single or “universal” knowledge organization systems. There is a recurrence of concepts of warrant buttressing the extension of research into issues of culture and identity. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 10.1 (2003) 25-27 [Access article in PDF] Gender, Body, Meaning:Anthropological Perspectives on Self-Injury and Borderline Personality Disorder Carolyn Sargent THE CENTRAL THEMES OF "Commodity Body/Sign: Borderline Personality Disorder and the Signification of Self-Injurious Behavior" reflect issues that cut across the disciplines represented by this journal and have received increasing attention from anthropologists. Medical anthropologists, as well as psychological anthropologists and others interested in symbolic analysis (...) of the body, have addressed such topics as the culture of biomedicine and the cultural shaping of psychiatric classification, the multiple meanings of body modifications, power relations in therapeutic interactions between doctor and patient, and cultural variation in understandings of normality and abnormality.Curiously, there is little anthropological literature that directly focuses on either borderline personality disorder (BPD) or self-injurious acts per se. Indeed anthropological research on psychiatric diagnosis, classification, and treatment, as well as ethnopsychiatry, include scant reference to personality disorders. One exception is Nuckolls' 1992 article, "Toward a Cultural History of the Personality Disorders," which raises pertinent questions for one of Potter's introductory statements—that the majority of those diagnosed with BPD are women. Nuckolls directly addresses gender ideology and gender roles in the United States in his comparison of antisocial personality and histrionic personality diagnoses. In his paper, he argues that these personality disorders have cultural histories and are strongly congruent with prevailing gender stereotypes, such that men are many times more likely to be diagnosed as antisocial than women and women much more likely to be diagnosed as histrionic (Nuckolls 1992, 37). He also historicizes the emergence of certain behavioral styles that have been seen as characteristic of women and men, and the evolution of psychiatric diagnoses that classify extreme manifestations of these behavioral styles.The issue of why women, rather than men, are more frequently diagnosed with BPD is not elaborated in Potter's article, although she notes the importance of considering the intersection of gender and "identifying behaviors" associated with BPD. Cultural analyses of gender ideology in the [End Page 25] United States might suggest that the connection involves gendered expectations concerning emotionality and relational context but these articulations remain intriguing and underexplored. One might speculate that BPD/self-injury occurs in the context of particular gender ideologies, perhaps in class-based, industrialized societies where the body is highly commodified. It appears that the history of this constellation of symptoms and behaviors remains to be written.Cultural analysis of self-injury, a theme that runs through Potter's article, tends to be embedded in the anthropological literature on body ornamentation, initiation rituals, and "culture-bound" syndromes. Mascia-Lees and Sharpe (1992, 1) describe the body as "a site of adornment, manipulation, and mutilation," practices with roots reaching back as far as 30,000 years, and include as examples head deformation, scarification, foot binding, tooth filing, lip plates, nose rings, tattoos, subincision, and genital cutting.However, the concept of self-injury, as Potter notes, is problematic in the discipline of anthropology given the significance historically accorded to cultural relativism. Correspondingly, body "modification" is not "self-injury" as long as it is socially normative, for example, a facet of an initiation ordeal or body ornamentation (e.g., circumcision, scarification, piercing). Among the rare examples of acts that seem readily identifiable as "self-injury" are New Guinea practices of cutting off a finger to demonstrate mourning and Baatombu (West African) male finger amputation to show grief and anger over a wife's infidelity. Both are, however, considered culturally legitimate and not indicative of pathology.Potter's argument draws heavily on the notion of "body as text," derived largely from literary theory and feminist philosophy (Butler 1990; Jaggar and Bordo 1989). The perspective of "body as text" has influenced anthropological theory over the past two decades, particularly in the interpretive and postmodernist schools of thought. The body as a text of femininity is aptly characterized by Bordo, who argues that the continuum between female disorder and normal femininity is revealed by means of an analysis of symbolic meaning of gender in...

Norman in 1969 emphasised a linguistic difference between the Vedic compound yogakṣema- interpreted as a dvandva and the widely distributed Early Buddhist compound yogakkhema-, analysed as a tatpuruṣa “rest from exertion”. On the basis of our analysis of the relevant Pali sources and of the more ancient Vedic occurrences—some of which are quite far from the earliest denotation of the two cyclic phases of the assumed semi-nomadic Indo-Āryan life—we have undertaken a classification of the several meanings of this compound, in (...) order to distinguish their different facets and to enable us to easily bring about the comparison proposed by Norman in 1969 and in 1993 [1991]. Unlike Norman, we eventually postulated a common reading of this compound as a tatpuruṣa originally denoting an almost material target of welfare, from which both the Brāhmaṇic and the Buddhist usages, whose meaning is predominantly immaterial, might have developed.

This groundbreaking handbook of character strengths and virtues is the first progress report from a prestigious group of researchers who have undertaken the systematic classification and measurement of widely valued positive traits.

One of the main objectives of an ethics program is to improve the ethical culture of an organization. To date, empirical research treats at least one of these concepts as a one-dimensional construct. This paper demonstrates that by conceptualizing both constructs as multi-dimensional, a more in-depth understanding of the relationship between the two concepts can be achieved. Through the employment of the Corporate Ethical Virtues Model, eight dimensions of ethical culture are distinguished. Nine components of an ethics program are identified. (...) To assess the relationship between ethics programs and ethical culture, a survey was conducted of 4,056 members of the U. S. working population. The results show that the relationships between the components of an ethics program and the dimensions of ethical culture differ in strength, nature, and significance. Implications for research and practice are discussed. (shrink)

A large part of the controversy surrounding the publication of DSM-5 stems from the possibility of replacing the purely descriptive approach to classification favored by the DSM since 1980. This paper examines the question of how mental disorders should be classified, focusing on the issue of whether the DSM should adopt a purely descriptive or theoretical approach. I argue that the DSM should replace its purely descriptive approach with a theoretical approach that integrates causal information into the DSM’s descriptive diagnostic (...) categories. The paper proceeds in three sections. In the first section, I examine the goals (viz., guiding treatment, facilitating research, and improving communication) associated with the DSM’s purely descriptive approach. In the second section, I suggest that the DSM’s purely descriptive approach is best suited for improving communication among mental health professionals; however, theoretical approaches would be superior for purposes of treatment and research. In the third section, I outline steps required to move the DSM towards a hybrid system of classification that can accommodate the benefits of descriptive and theoretical approaches, and I discuss how the DSM’s descriptive categories could be revised to incorporate theoretical information regarding the causes of disorders. I argue that the DSM should reconceive of its goals more narrowly such that it functions primarily as an epistemic hub that mediates among various contexts of use in which definitions of mental disorders appear. My analysis emphasizes the importance of pluralism as a methodological means for avoiding theoretical dogmatism and ensuring that the DSM is a reflexive and self-correcting manual. (shrink)

Contemporary psychiatry finds itself in the midst of a crisis of classification. The developments begun in the 1980s—with the third edition of the Diagnostic and Statistical Manual of Mental Disorders —successfully increased inter-rater reliability. However, these developments have done little to increase the predictive validity of our categories of disorder. A diagnosis based on DSM categories and criteria often fails to accurately anticipate course of illness or treatment response. In addition, there is little evidence that the DSM categories link up (...) with genetic findings, and even less evidence that they... (shrink)

This study aimed to identify real-life experts working for a port authority and lay people (students) who played The Sustainable Port, a serious game aiming to simulate the dynamics occurring in a port area. To achieve this goal, we analyzed eye gaze data collected noninvasively using low-grade webcams from 28 participants working for the port authority of the Port of Rotterdam and 66 students. Such data were used for a classification task implemented using a MiniRocket classifier, an algorithm used for (...) time-series classification. The classifier reached an F1 score of 0.75 (SD = 0.07), a PR AUC of 0.73 (SD = 0.14), and an ROC AUC of 0.75 (SD = 0.15) providing evidence that it is possible to identify real-life experts about maritime port management using data that can be obtained from a webcam. We speculate that the gaze direction used to train the MiniRocket may contain relevant information about the cognitive processes and decisions occurring throughout the gameplay. We suggest that the methods here presented not only can be used to detect experts playing simulations, such as serious games, but also to identify experts tackling screen-presented tasks. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 9.3 (2002) 219-227 [Access article in PDF] The Practical Kinds Model as a Pragmatist Theory of Classification Peter Zachar Pragmatist theories of scientific classification are intended to be pluralistic models that recognize different ways of cutting up the world as valuable, but do not require us to adopt whatever-goes relativism or metaphysical antirealism. How ironic that my application of pragmatism to psychopathology has been charged (...) with not being sufficiently pluralistic because it tries to fit all psychiatric disorders into the Procrustean bed of practical kinds. The Practical Kinds Model in General As a point of clarification, the practical kinds model is not a description of a type of category combined with an argument that all psychiatric disorders should be seen as belonging to that type. If it were that kind of model, I would fully agree with Haslam that practical kinds, fuzzy kinds, and discrete kinds are all potential types of psychiatric disorders. Like Nick Haslam, I believe that there are many different things in the DSM-IV and the ICD-10, and they cannot neatly be classified as the same type of thing.Rather than identifying a type of category, the practical kinds model is a general theory of scientific classification. It is a nonessentialistic theory. Essentialism is the view that things have real essences. In the Aristotelian version of essentialism, an essence is an internal structure, and it is the internal structure that makes anything be the kind of thing it really is. In this classical category model, category members either have the essence or they do not, and everything that has the appropriate essence is a member of that category. The world is supposed to therefore have a well-defined structure, and the job of the scientist is to discover that structure. Ian Hacking (1999) has termed this view of categorization inherent structurism.The practical kinds model does not deny that things have internal structures; it only denies that internal structure by itself determines category membership. Internal structure is an important consideration in identifying categories, but external criteria can always play a role. External or relational criteria play more important roles in some cases than they do in others, but they cannot be eliminated once and for all. Essentialistic theories, which favor an almost exclusive focus on inherent structures, have the advantage of being more parsimonious, but they do so by ignoring real complexity.The best way to illustrate this point is to examine a category whose identification is heavily weighted in terms of internal criteria, or an inherent structure, such as a chemical element. [End Page 219] For example, hydrogen is defined as the element that has an atomic number of 1. This means that it has one proton in its nucleus and normally one electron orbiting its nucleus. The atomic number reflects an internal property, and anything that has an atomic number of 1 is hydrogen. The same is true for the other elements. Anything that has an atomic number of 79 is gold; anything that has an atomic number of 19 is potassium, and so on. Also part of the essentialistic view is the notion that all the important properties of an element are systematically (or lawfully) related to its internal structure.It would be foolish to deny the practical utility of the atomic theory of chemistry. But even in this strongest of cases, external criteria can potentially play a role in how we decide to carve up the world and what we identify as the relevant categories. The point can be clearly illustrated with a Gedanken experiment based on the ideas of Donnellan (1983). Assume that we were to make contact with extraterrestrial life, and the result of that contact was our initiation into a larger galactic community like those portrayed on Star Trek or Babylon 5. Fortunately for us, it turns out that all planets in the community use a gold-based currency, just like we do on Earth. What we call gold, however, is too common to be the galactic basis of a currency, but a particular isotope... (shrink)

The classification of the sciences is one of the most discussed and analysed aspects of Peirce’s corpus of work. I propose that Peirce’s attempt at systematising the sciences is characterised by a distinctive historicity, which I construe in two complementary senses. First, I investigate Peirce’s classification as part of a broader nineteenth-century move toward classifying the sciences, a move that was at the same time motivated by social and epistemological goals. I claim that this re-contextualisation adds an entirely new layer (...) to the otherwise distinctively internalist readings of Peirce’s classification. I then look at how Peirce’s scheme, especially in the form it displayed in the early 1890s, relates to his own historical writings, particularly his history of science. Looking at Peirce as a historical actor in his own right through the lens of his classification, I claim, is indispensable to understand the contemporary relevance of his contributions to the history and historiography of the sciences.

The general aim of this article is to give a critical interpretation of post-trial obligations towards individual research participants in the Declaration of Helsinki 2013. Transitioning research participants to the appropriate health care when a research study ends is a global problem. The publication of a new version of the Declaration of Helsinki is a great opportunity to discuss it. In my view, the Declaration of Helsinki 2013 identifies at least two clearly different types of post-trial obligations, specifically, access to (...) care after research and access to information after research. The agents entitled to receive post-trial access are the individual participants in research studies. The Declaration identifies the sponsors, researchers and host country governments as the main agents responsible for complying with the post-trial obligations mentioned above. To justify this interpretation of post-trial obligations, I first introduce a classification of post-trial obligations and illustrate its application with examples from post-trial ethics literature. I then make a brief reconstruction of the formulations of post-trial obligations of the Declaration of Helsinki from 2000 to 2008 to correlate the changes with some of the most salient ethical arguments. Finally I advance a critical interpretation of the latest formulation of post-trial obligations. I defend the view that paragraph 34 of ‘Post-trial provisions’ is an improved formulation by comparison with earlier versions, especially for identifying responsible agents and abandoning ambiguous ‘fair benefit’ language. However, I criticize the disappearance of ‘access to other appropriate care’ present in the Declaration since 2004 and the narrow scope given to obligations of access to information after research.

Psychiatric classification, as exemplified by the Diagnostic and Statistical Manual of Mental Disorders, is dealing with a lack of trust and credibility—in the scientific, but also in the public realm. Regarding the latter in particular, one possible remedial measure for this crisis in trust lies in an increased integration of patients into the DSM revision process. The DSM, as a manual for clinical practice, is forced to make decisions that exceed available data and involve value-judgments. Regarding such decisions, public epistemic (...) trustworthiness requires that these value-judgments should be representative of those of the affected public, and that the public has a reason to believe such a representation to be realized. Due to the long tradition of distrust in psychiatry, such a reason can in this case best be provided by an actual integration of patients into the decision-making process, rather than by their representation through scientific experts.

The philosophy of medicine and psychiatry has considered the defining of disease, illness, and disorder an important project for over three decades. Within this literature, accounts based on adaptive "functions" have been prominent, particularly in the DSM nosology. In response to this trend, Jerome Wakefield has presented a view of mental disorder as "harmful dysfunction." In this view, "harm" contributes the value-element to disorder concepts, while "dysfunction" implies a value-free foundation as long as the latter is grounded in evolutionary biology. (...) In a critical review of Wakefield's and others' functionalist arguments for disorder concepts, we make four major points. We recommend a shift away from the definition of value-free disorder concepts, instead emphasizing the analysis of the logical features and the value commitments in nosological categories. (shrink)

In this essay several challenges are raised to the project of classifying Śāntideva’s ethical reasoning given in his Bodhicaryāvatāra, or Guide to the Way of the Bodhisattva, as a species of ethical theory such as consequentialism or virtue ethics. One set of difficulties highlighted here arises because Śāntideva wrote this text to act as a manual of psychological transformation, and it is therefore often difficult to determine when his statements indicate his own ethical views. Further, even assuming we can identify (...) a set of statements that accurately portray the moral position of Śāntideva, it is argued that these statements underdetermine which foundational normative theory should be ascribed to him.

John Doris has recently argued that since we do not possess character traits as traditionally conceived, virtue ethics is rooted in a false empirical presupposition. Gopal Sreenivasan has claimed, in a paper in Mind, that Doris has not provided suitable evidence for his empirical claim. But the experiment Sreenivasan focuses on is not one that Doris employs, and neither is it relevantly similar in structure. The confusion arises because both authors use the phrase ‘cross-situational consistency’ to describe the aspect of (...) character traits that they are concerned with, but neither defines this phrase, and it is ambiguous: Doris uses it in one sense, Sreenivasan in another. Partly for this reason, the objections Sreenivasan raises fail to block the argument Doris provides. In particular, the most reliable data Doris employs, Milgram’s famous study of authority, is entirely immune to Sreenivasan’s objections. Sreenivasan has not shown, therefore, that Doris provides unsuitable evidence for his claim. (shrink)

Characterizing how activity in the central and autonomic nervous systems corresponds to distinct emotional states is one of the central goals of affective neuroscience. Despite the ease with which individuals label their own experiences, identifying specific autonomic and neural markers of emotions remains a challenge. Here we explore how multivariate pattern classification approaches offer an advantageous framework for identifying emotion-specific biomarkers and for testing predictions of theoretical models of emotion. Based on initial studies using multivariate pattern classification, we suggest that (...) central and autonomic nervous system activity can be reliably decoded into distinct emotional states. Finally, we consider future directions in applying pattern classification to understand the nature of emotion in the nervous system. (shrink)

We extend the hierarchy of finite-dimensional Ellentuck spaces to infinite dimensions. Using uniform barriers [Formula: see text] on [Formula: see text] as the prototype structures, we construct a class of continuum many topological Ramsey spaces [Formula: see text] which are Ellentuck-like in nature, and form a linearly ordered hierarchy under projections. We prove new Ramsey-classification theorems for equivalence relations on fronts, and hence also on barriers, on the spaces [Formula: see text], extending the Pudlák–Rödl theorem for barriers on the Ellentuck (...) space. The inspiration for these spaces comes from continuing the iterative construction of the forcings [Formula: see text] to the countable transfinite. The [Formula: see text]-closed partial order [Formula: see text] is forcing equivalent to [Formula: see text], which forces a non-p-point ultrafilter [Formula: see text]. This work forms the basis for further work classifying the Rudin–Keisler and Tukey structures for the hierarchy of the generic ultrafilters [Formula: see text]. (shrink)

A passive brain–computer interface based upon functional near-infrared spectroscopy brain signals is used for earlier detection of human drowsiness during driving tasks. This BCI modality acquired hemodynamic signals of 13 healthy subjects from the right dorsolateral prefrontal cortex of the brain. Drowsiness activity is recorded using a continuous-wave fNIRS system and eight channels over the right DPFC. During the experiment, sleep-deprived subjects drove a vehicle in a driving simulator while their cerebral oxygen regulation state was continuously measured. Vector phase analysis (...) was used as a classifier to detect drowsiness state along with sleep stage-based threshold criteria. Extensive training and testing with various feature sets and classifiers are done to justify the adaptation of threshold criteria for any subject without requiring recalibration. Three statistical features along with six VPA features were used. The average accuracies for the five classifiers are 90.9% for discriminant analysis, 92.5% for support vector machines, 92.3% for nearest neighbors, 92.4% for both decision trees, and ensembles over all subjects’ data. Trajectory slopes of CORE vector magnitude and angle: m and m are the best-performing features, along with ensemble classifier with the highest accuracy of 95.3% and minimum computation time of 40 ms. The statistical significance of the results is validated with a p-value of less than 0.05. The proposed passive BCI scheme demonstrates a promising technique for online drowsiness detection using VPA along with sleep stage classification. (shrink)
