There is growing agreement among taxonomists that species are independently evolving lineages. The central notion of this conception, evolutionary independence, is commonly operationalized by taxonomists in multiple, diverging ways. This leads to a problem of operationalization-dependency in species classification, as species delimitation is not only dependent on the properties of the investigated groups, but also on how taxonomists choose to operationalize evolutionary independence. The question then is how the operationalization-dependency of species delimitation is compatible with its objectivity and reliability. In (...) response to this problem, various taxonomists have proposed to integrate multiple operationalizations of evolutionary independence for delimiting species. This paper first distinguishes between a standard and a sophisticated integrative approach to taxonomy, and argues that it is unclear how either of these can support the reliability and objectivity of species delimitation. It then draws a parallel between the measurement of physical quantities and species delimitation to argue that species delimitation can be considered objective and reliable if we understand the sophisticated integrative approach as assessing the coherence between the idealized models of multiple operationalizations of evolutionary independence.

In this paper, we argue that the concept of environmental scaffolding can contribute to a better understanding of our affective life and the complex manners in which it is shaped by environmental entities. In particular, the concept of environmental scaffolding offers a more comprehensive and less controversial framework than the notions of embeddedness and extendedness. We contribute to the literature on situated affectivity by embracing and systematizing the diversity of affective scaffolding. In doing so, we introduce several distinctions that provide (...) classifications of different types of environmentally scaffolded affectivity. Furthermore, we differentiate eight dimensions that allow us to evaluate the quality and effectivity of scaffolds in particular applications. On that basis, we develop a taxonomy using paradigmatic examples of affective scaffolding. This taxonomy enriches the current debate by emphasizing distinctions that are often conflated and by identifying fields of application that are commonly overlooked. (shrink)

A taxonomy of part‐whole or meronymic relations is developed to explain the ordinary English‐speaker's use of the term “part of” and its cognates. The resulting classification yields six types of meronymic relations: 1. component‐integral object (pedal‐bike), 2. member‐collection (ship‐fleet), 3. portion‐mass (slice‐pie), 4. stuff‐object (steel‐car), 5. feature‐activity (paying‐shopping), and 6. place‐area (Everglades‐Florida). Meronymic relations ore further distinguished from other inclusion relations, such as spatial inclusion, and class inclusion, and from several other semantic relations: attribution, attachment, and ownership. This (...) class='Hi'>taxonomy is then used to explain cases of apparent intransitivity in merological syllogisms, and standard form syllogisms whose premises express different inclusion relations. The data suggest that intransitivities arise due to equivocations between different types of semantic relations. These results are then explained by means of the relation element theory which accounts for the character and behavior of semantic relations in terms of more primitive relational elements. The inferential phenomena observed are then explained by means of a single principle of element matching. (shrink)

When we ask what natural kinds are, there are two different things we might have in mind. The first, which I’ll call the taxonomy question, is what distinguishes a category which is a natural kind from an arbitrary class. The second, which I’ll call the ontology question, is what manner of stuff there is that realizes the category. Many philosophers have systematically conflated the two questions. The confusion is exhibited both by essentialists and by philosophers who pose their accounts (...) in terms of similarity. It also leads to misreading philosophers who do make the distinction. Distinguishing the questions allows for a more subtle understanding of both natural kinds and their underlying metaphysics. (shrink)

Due to the ongoing advancements in technology, socio-technical collaboration has become increasingly prevalent. This poses challenges in terms of governance and accountability, as well as issues in various other fields. Therefore, it is crucial to familiarize decision-makers and researchers with the core of human–machine collaboration. This study introduces a taxonomy that enables identification of the very nature of human–machine interaction. A literature review has revealed that automation and technical autonomy are main parameters for describing and understanding such interaction. Both (...) aspects must be carefully evaluated, as their increase has potentially far-reaching consequences. Hence, these two concepts comprise the taxonomy’s axes. Five levels of automation and five levels of technical autonomy are introduced below, based on the assumption that both automation and autonomy are gradual. The levels of automation were developed from existing approaches; those of autonomy were carefully derived from a review of the literature. The taxonomy’s use is also explained, as are its limitations and avenues for further research. (shrink)

In introgressive hybridization (the repeated backcrossing of hybrids with parental populations), Edgar Anderson found a source for variation upon which natural selection could work. In his 1953 review article “Introgressive Hybridization,” he asserted that he was “bringing taxonomy to the service of genetics” whereas distinguished colleagues such as Theodosius Dobzhansky and Ernst Mayr did the precise opposite. His work as a geneticist particularly focused on linkage and recombination and was enriched by collaborations with Missouri Botanical Garden colleagues interested in (...) taxonomy as well as with cytologists C.D. Darlington and Karl Sax. As the culmination of a biosystemtatic research program, Anderson’s views challenged the mainstream of the Evolutionary Synthesis. -/- . (shrink)

Spiritual Taxonomies and Ritual Authority recounts how philosophers of the late third century C.E. organized the spirit world into hierarchies, positioning themselves as high priests in the process. By establishing themselves as experts on sacred matters, they fortified their authority, prestige, and reputation.

_ Source: _Volume 47, Issue 3, pp 429 - 448 Taxonomy is our response to the proliferating variety of the natural world on the one hand, and the principle of unrelieved universality on the other. From Aristotle, through Porphyry to Linneaus, Kant and others, thinkers have struggled to develop taxonomies that could order what we know and also what we do not yet know, and this essay is a reflection on the existential desire that propels this effort. Porphyry’s tree (...) of logic is an exhaustive account of the things we can say about the sort of beings we are; Linneaus’s system of nature reaches completion in the classification of humans; Kant discovers a way to have natural and logical forms coincide in the thought of natural purpose and purposiveness. The stakes are high. When we order the world, we order ourselves: when we enter the taxonomy, it enters us and confronts us with our judgments of kind, race and kin. (shrink)

The relation between conservation science and taxonomy is typically seen as a simple dependency of the former on the latter. This dependency is assumed to be strictly one-way to avoid normative concerns from conservation science inappropriately affecting the descriptive discipline of taxonomy. In this paper, I argue against this widely assumed standard view on the relation between these two disciplines by highlighting two important roles for conservation scientists in scientific decisions that are part of the internal stages of (...) taxonomy. I show that these roles imply that the two disciplines should be interdependent and that value-judgments should play a substantial role in both. (shrink)

Kuhn's alleged taxonomic interpretation of incommensurability is grounded on an ill defined notion of untranslatability and is hence radically incomplete. To supplement it, I reconstruct Kuhn's taxonomic interpretation on the basis of a logical-semantic theory of taxonomy, a semantic theory of truth-value, and a truth-value conditional theory of cross-language communication. According to the reconstruction, two scientific languages are incommensurable when core sentences of one language, which have truth values when considered within its own context, lack truth values when considered (...) within the context of the other due to the unmatchable taxonomic structures underlying them. So constructed, Kuhn's mature interpretation of incommensurability does not depend upon the notion of truth-preserving translatability, but rather depends on the notion of truth-value-status-preserving cross-language communication. The reconstruction makes Kuhn's notion of incommensurability a well grounded, tenable and integrated notion.Author Keywords: Incommensurability; Thomas Kuhn; Taxonomic structures; Lexicons; Truth-value; Untranslatability; Cross-language communication.

The goal of this paper is to develop a systematic taxonomy of cognitive artifacts, i.e., human-made, physical objects that functionally contribute to performing a cognitive task. First, I identify the target domain by conceptualizing the category of cognitive artifacts as a functional kind: a kind of artifact that is defined purely by its function. Next, on the basis of their informational properties, I develop a set of related subcategories in which cognitive artifacts with similar properties can be grouped. In (...) this taxonomy, I distinguish between three taxa, those of family, genus, and species. The family includes all cognitive artifacts without further specifying their informational properties. Two genera are then distinguished: representational and non-representational (or ecological) cognitive artifacts. These genera are further divided into species. In case of representational artifacts, these species are iconic, indexical, or symbolic. In case of ecological artifacts, these species are spatial or structural. Within species, token artifacts are identified. The proposed taxonomy is an important first step towards a better understanding of the range and variety of cognitive artifacts and is a helpful point of departure, both for conceptualizing how different artifacts augment or impair cognitive performance and how they transform and are integrated into our cognitive system and practices.

Taxonomy Based modeling was applied to describe drivers’ mental models of variable message signs (VMS’s) displayed on expressways. Progress in road telematics has made it possible to introduce variable message signs (VMS’s). Sensors embedded in the carriageway every 500m record certain variables (speed, flow rate, etc.) that are transformed in real time into “driving times” to a given destination if road conditions do not change.VMS systems are auto-regulative Man-Machine (AMMI) systems which incorporate a model of the user: if the (...) traffic flow is too high, then drivers should choose alternative routes. In so doing, the traffic flow should decrease. The model of the user is based on suppositions such as: people do not like to waste time, they fully understand the displayed messages, they trust the displayed values, they know of alternative routes. However, people also have a model of the way the system functions. And if they do not believe the contents of the message, they will not act as expected.We collected data through interviews with drivers using the critical incidents technique (Flanagan, 1985). Results show that the mental models that drivers have of the way the VMS system works are various but not numerous and that most of them differ from the“ideal expert” mental model. It is clear that users don’t have an adequate model of how the VMS system works and that VMS planners have a model of user behaviour that does not correspond to the behaviour of the drivers we interviewed. Finally, Taxonomy Based Modeling is discussed as a tool for mental model remediation. (shrink)

This essay explores the intersection of race science and plant taxonomy in the creation of evolutionary taxonomies (phylogenies) of populations of Zea mays, also known as maize or corn. Following recent work in the history and sociology of race, it analyzes maize taxonomy as technology. Through an analysis of successive attempts to classify diverse maize varieties, especially those originating in Mexico, it shows that taxonomy created possibilities for researchers to intervene in commercial agriculture, state development projects, biological (...) conservation, and domestic and international politics and policy. It further underscores that the modern science of maize taxonomy was distinct but never inseparable from assessments of maize’s human cultivators. Attending to particularities of this relationship is crucial, because it reveals the application of maize taxonomy as a technology for ordering human diversity and intervening in human lives, as well as managing the impressive diversity of Zea mays.

Why might alternative taxonomies be needed in contemporary life, and how might the notion of categorisation or anti-categorisation be thought speculatively? This essay considers some of the ways that life and matter have been historically divided and segmented and asks how this might be rendered mobile, offering new divisions and definitions for those who exist outside hegemonic segments or scales.

Both scientists and philosophers of science have recently emphasized the importance of promoting transparency in science. For scientists, transparency is a way to promote reproducibility, progress, and trust in research. For philosophers of science, transparency can help address the value-ladenness of scientific research in a responsible way. Nevertheless, the concept of transparency is a complex one. Scientists can be transparent about many different things, for many different reasons, on behalf of many different stakeholders. This paper proposes a taxonomy that (...) clarifies the major dimensions along which approaches to transparency can vary. By doing so, it provides several insights that philosophers and other science studies scholars can pursue. In particular, it helps address common objections to pursuing transparency in science, it clarifies major forms of transparency, and it suggests avenues for further research on this topic. (shrink)

Although naming biological clades is a major activity in taxonomy, little attention has been paid to what these names actually refer to. In philosophy, definite descriptions have long been considered equivalent to the meaning of names and biological taxonomy is a scientific application of these ideas. One problem with definite descriptions as the meanings of names is that the name will refer to whatever fits the description rather than the intended individual (clade). Recent proposals for explicit phylogenetic definitions (...) of clade names suffer from similar problems and we argue that clade names cannot be defined since they lack intension. Furthermore we stress the importance of tree-thinking for phylogenetic reference to work properly. (shrink)

A topological classification scheme consists of two ingredients: (1) an abstract class K of topological spaces; and (2) a "taxonomy", i.e. a list of first order sentences, together with a way of assigning an abstract class of spaces to each sentence of the list so that logically equivalent sentences are assigned the same class. K is then endowed with an equivalence relation, two spaces belonging to the same equivalence class if and only if they lie in the same classes (...) prescribed by the taxonomy. A space X in K is characterized within the classification scheme if whenever Y ∈ K and Y is equivalent to X, then Y is homeomorphic to X. As prime example, the closed set taxonomy assigns to each sentence in the first order language of bounded lattices the class of topological spaces whose lattices of closed sets satisfy that sentence. It turns out that every compact two-complex is characterized via this taxonomy in the class of metrizable spaces, but that no infinite discrete space is so characterized. We investigate various natural classification schemes, compare them, and look into the question of which spaces can and cannot be characterized within them. (shrink)

This short article is a commentary to ‘Vulnerability in Research Ethics: A way forward’ from Margaret Meek Lange, Wendy Rogers and Susan Dodds. In their article they describe and accept my criticisms of the subpopulation approach to vulnerability and my analysis of vulnerability based on layers, but they suggest going beyond it using a taxonomy to classify layers of vulnerabilty. I argue that a) we do not need a taxonomy to classify vulnerabilities, b) the authors do not provide (...) an adequate or successful taxonomy, and c) they are unable to link their taxonomy to specific obligations. Thus I propose avoiding an approach that requires taxonomies, and suggest instead using some characteristics of layers of vulnerability. (shrink)

Wearable robots and exoskeletons are relatively new technologies designed for assisting and augmenting human motor functions. Due to their different possible design applications and their intimate connection to the human body, they come with specific ethical, legal, and social issues, which have not been much explored in the recent ELS literature. This paper draws on expert consultations and a literature review to provide a taxonomy of the most important ethical, legal, and social issues of wearable robots. These issues are (...) categorized in wearable robots and the self, wearable robots and the other, and wearable robots in society. (shrink)

In his mature works, Kuhn abandons the concept of a paradigm and becomes more interested in the analysis of the conceptual structure of scientific theories. These changes are interpreted as resulting from a ‘linguistic turn’ that Kuhn underwent sometimes around the 1980s. Much of the philosophical discussions about Kuhn’s post-‘linguistic turn’ philosophy revolves around his views on taxonomic concepts. Apart from taxonomy, however, the mature Kuhn introduces other concepts, such as conceptual networks and lexicons. This article distinguishes these three (...) concepts and shows that adopting each one of them has different impacts on Kuhn’s model of science. After distinguishing and assessing the concepts of taxonomy, network, and lexicon, it will be argued that the latter not only fits the Kuhnian model of science better, but it also helps capture the wide sense of Kuhn’s early concept of a paradigm.

Mary Winsor (2003) argues against the received view that pre-Darwinian taxonomy was characterized mainly by essentialism. She argues, instead, that the methods of pre-Darwinian taxonomists, in spite of whatever their beliefs, were that of clusterists, so that the received view, propagated mainly by certain modern biologists and philosophers of biology, should at last be put to rest as a myth. I argue that shes right when it comes to higher taxa, but wrong when it comes the most important category (...) of all, the species category. (shrink)

Trainers often use information from previous learning sessions to design or redesign a course. Although universities conducted numerous research integrity training in the past decades, information on what works and what does not work in research integrity training are still scattered. The latest meta-reviews offer trainers some information about effective teaching and learning activities. Yet they lack information to determine which activities are plausible for specific target groups and learning outcomes and thus do not support course design decisions in the (...) best possible manner. This article wants to change this status quo and outlines an easy-to-use taxonomy for research integrity training based on Kirkpatrick’s four levels of evaluation to foster mutual exchange and improve research integrity course design. By describing the taxonomy for research integrity training (TRIT) in detail and outlining three European projects, their intended training effects before the project started, their learning outcomes, teaching and learning activities, and their assessment instruments, this article introduces a unified approach. This article gives practitioners references to identify didactical interrelations and impacts and (knowledge) gaps in how to (re-)design an RI course. The suggested taxonomy is easy to use and enables an increase in tailored and evidence-based (re-)designs of research integrity training. (shrink)

We discuss the impact of horizontal gene transfer (HGT) on phylogenetic reconstruction and taxonomy. We review the power of HGT as a creative force in assembling new metabolic pathways, and we discuss the impact that HGT has on phylogenetic reconstruction. On one hand, shared derived characters are created through transferred genes that persist in the recipient lineage, either because they were adaptive in the recipient lineage or because they resulted in a functional replacement. On the other hand, taxonomic patterns (...) in microbial phylogenies might also be created through biased gene transfer. The agreement between different molecular phylogenies has encouraged interpretation of the consensus signal as reflecting organismal history or as the tree of cell divisions; however, to date the extent to which the consensus reflects shared organismal ancestry and to which it reflects highways of gene sharing and biased gene transfer remains an open question. Preferential patterns of gene exchange act as a homogenizing force in creating and maintaining microbial groups, generating taxonomic patterns that are indistinguishable to those created by shared ancestry. To understand the evolution of higher bacterial taxonomic units, concepts usually applied in population genetics need to be applied. (shrink)

Work with people with Williams syndrome is reviewed relative to Atran's claim that the universality of taxonomic rank in the animal and plant domains derives from a biological construal of generic species. From this work it is argued that a biological construal of animals is not necessary for the construction of the adult taxonomy of animals and therefore that the existence of an animal (or plant) taxonomy cannot be taken as evidence of a biological domain.

We find the claim that time is not real in both western and eastern philosophical traditions. In what follows I will call the view that time does not exist temporal error theory. Temporal error theory was made famous in western analytic philosophy in the early 1900s by John McTaggart (1908) and, in much the same tradition, temporal error theory was subsequently defended by Gödel (1949). The idea that time is not real, however, stretches back much further than that. It is (...) common to hear it said that according to Buddhist philosophy (as though that were a monolithic view) time is illusory. While it is not true that, in general, either contemporary or ancient Buddhist scholars have thought time to be illusory, there are certainly some schools of Buddhist thought, such as that of traditional Dzogchen practitioners, according to which there is no time. This paper is an attempt to set out a taxonomy of different views about what it takes for there to be time and, alongside that, a taxonomy of views about whether there is time or not, and if there is time what it is like.

This essay examines the ambition to taxonomize law and the different methods a legal taxonomer might employ. Three possibilities emerge. The first is a formal taxonomy that classifies legal materials according to rules of order and clarity. Formal taxonomy is primarily conventional and has no normative implications for judicial decision-making. The second possibility is a function-based taxonomy that classifies laws according to their social functions. Function-based taxonomy can influence legal decision-making indirectly, as a gatekeeping mechanism, but (...) it does not provide decisional standards for courts. Its objective is to assist in analysis and criticism of law by providing an overview of the body of legal doctrine. The third possibility is a reason-based taxonomy that classifies legal rules and decisions according to the moral principles or “legal principles” thought to justify them. Reason-based taxonomy of this type offers courts a set of high-level decisional rules drawn from legal data. Its objective is to guide courts in deciding new cases and evaluating precedents. A predominantly formal taxonomy facilitates legal analysis and communication. A functional taxonomy can assist those who make and apply law by providing a purposive overview of the field. Reason-based taxonomy may be useful to lawmakers but is unhelpful when offered as a guide to adjudication of disputes. (shrink)

The emerging field of quantum mereology considers part-whole relations in quantum systems. Entangled quantum systems pose a peculiar problem in the field, since their total states are not reducible to that of their parts. While there exist several established proposals for modelling entangled systems, like monistic holism or relational holism, there is considerable unclarity, which further positions are available. Using the lambda operator and plural logic as formal tools, we review and develop conceivable models and evaluate their consistency and distinctness. (...) The main result is an exhaustive taxonomy of six distinct and precise models that both provide information about the mereological features as well as about the entangled property. The taxonomy is well-suited to serve as the basis for future systematic investigations. (shrink)

The history of science often has difficulty connecting with science at the lab-bench level, raising questions about the value of history of science for science.

In particular, it argues that an unwillingness to deal with messy theoretical questions in both cases leads to important problems (...) in the theory and practice of identifying taxa. This argument makes use of scientific and historical considerations in a way that the authors hope leads to convincing conclusions about the history of taxonomy as well as about its present practice.

Hare explains what he means by ‘Ethical Theory’, and what he means by ‘Taxonomy’. Ethical theory, which Hare contrasts to ‘moral theory’, is a purely formal discipline that is concerned with the meaning and logical properties of moral words. Hare offers a ‘Taxonomy’ of ethical theories in the sense of a classification into genera and differentia, beginning with what he sees as the basic dichotomy in ethical theory between descriptivism and non‐descriptivism. The difference between descriptivist and non‐descriptivist ethical (...) theories is that, according to the former, the meaning of moral statements is determined entirely by their truth conditions; the latter deny that this is so. Hare divides descriptivism into ‘Naturalism’ and ‘Intuitionism’, and non‐descriptivism into ‘Emotivism’ and ‘Rationalism’. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Folk Taxonomies Versus Official TaxonomiesNick Haslam (bio)Keywordsclassification, DSM-IV, folk taxonomyFlanagan and Blashfield’s paper continues a highly original program of research on clinicians’ understandings of psychopathology. This work is unique in bringing concepts and methods from cognitive anthropology to bear on psychiatric classification. At first blush, it might seem questionable to treat clinicians’ beliefs about psychiatric disorders as folk taxonomies, no different in kind from classifications of birds produced by (...) members of a forest-dwelling tribe. Unlike birds and other natural objects of folk taxonomies, mental disorders are not concrete entities and they cannot be distinguished on perceptual grounds. Unlike tribespeople, clinicians are not simply “folk” whose naïve classifications can be compared with those of scientific authorities. They are, in fact, heavily exposed to the reigning official taxonomy during their professional training, and their thinking can hardly remain unaffected by it. It is a testament to Flanagan and Blashfield’s work that despite these apparent disanalogies, their folk-taxonomic approach manages to illuminate how clinicians carve up the psychiatric domain.This paper reports some careful, creative, and labor-intensive studies to make a few fundamental claims about how clinicians classify. First, the authors argue that clinicians hold simplified taxonomies compared with the official DSM-IV taxonomy: They encompass fewer disorders and classify them in a shallower hierarchy. Second, they claim that clinicians substantially agree in how they classify disorders, and that a consensus classification can therefore be extracted from their individual taxonomies. Third, they argue that clinicians’ taxonomies show only a modest consistency with DSM-IV, and that the discrepancies may be systematic and important. Notably, for example, clinicians did not preserve the fundamental divide between the DSM’s Axes I and II. My comments address the second and third claims.Is There a “Consensus” among the Clinicians?One of the main achievements of Flanagan and Blashfield’s paper is to develop a “consensual taxonomy,” which is laid out in their Table 2a. This taxonomy clearly distils how their clinicians tended to judge the relations among diagnoses. However, it is an exaggeration to present it as a consensus. If, by Romney, Weller, and Batchelder’s (1986) third criterion, “cultural consensus” requires that the primary factor in a principal components analysis accounts for “most” of the variance in clinicians’ judgments, then Flanagan and Blashfield’s analysis [End Page 281] fails to show consensus. Their first factor accounts for only twenty-five percent of the variance, well short of the required majority. This finding implies that there is three times as much inconsistency or variability among clinicians’ taxonomic judgments than there is consistency and commonality. The observed factor-analytic findings are compatible with the average correlation between pairs of clinicians being only about 0.2, a very weak level of agreement.This is not to say that there is no consistency among the clinicians, or that there is no value in summarizing that consistency, but it does indicate that there is a great deal of diversity as well. Clinicians’ folk taxonomies seem to be highly idiosyncratic, more a Babel of distinctive classifications than a chorus of agreement. It is therefore risky to draw strong generalizations about how clinicians classify, and to imply that there is a single consensual taxonomy.Several things are very interesting about this diversity of classifications. First, Flanagan and Blashfield show that it cannot be explained by the clinicians’ differing levels of experience or by the different methodologies used to elicit their taxonomies. The variability among clinicians must therefore have some other basis, which awaits further investigation. Second, the level of agreement (“consensus”) obtained here is significantly lower than what has been found in more orthodox studies of folk taxonomy. By implication, the classification of psychiatric disorders is a slipperier enterprise than the classification of animals and plants. People who have extensive professional experience and training in the field of psychopathology—vocational training that includes the standardizing forces of accrediting bodies and a dominant psychiatric nosology—nevertheless tend not to agree substantially about how to map that territory. One guess about why this might be is that clinicians’ folk taxonomies are not merely descriptive maps of the interrelations among diagnostic entities, but are... (shrink)

The paper presents main conceptual distinctions underlying much of modern philosophical thinking about value. The introductory Section 1 is followed in Section 2 by an outline of the contrast between non-relational value and relational value. In Section 3, the focus is on the distinction between final and non-final value as well as on different kinds of final value. In Section 4, we consider value relations, such as being better/worse/equally good/on a par. Recent discussions suggest that we might need to considerably (...) extend traditional taxonomies of value relations. (shrink)

In an era of rising social awareness, both academics and practitioners have been concerned about the effectiveness of pro-social consumer influence strategies. The main assumption here is that for social marketing to succeed one must first understand the factors underlying pro-social consumer behavior. Firstly, drawing on two dimensions the authors first identify four types of social behavior. Next, the model describes social behavior as a result of preceding social behavior motivation and actual social behavior intention. Norms and economic evaluation have (...) an impact on social behavior motivation, which in turn influences social behavior intention, eventually leading to actual social behavior. Actual control factors, such as the availability of resources and opportunities, decide whether social behavior intention can really translate into actual social behavior. Finally, authors propose message strategies for each type of social behavior. (shrink)

Homeostatic Property Cluster (HPC) theory suggests that species and other biological taxa consist of organisms that share certain similarities. HPC theory acknowledges the existence of Darwinian variation within biological taxa. The claim is that “homeostatic mechanisms” acting on the members of such taxa nonetheless ensure a significant cluster of similarities. The HPC theorist’s focus on individual similarities is inadequate to account for stable polymorphism within taxa, and fails properly to capture their historical nature. A better approach is to treat distributions (...) of traits in species populations as irreducible facts, explained in terms of selection pressures, genealogy, and other evolutionary factors. We call this view Population Structure Theory (PST). PST accommodates the view, implicit in biological systematics, that species are identified by reference to particular historical populations.

The aims of this paper are to provide a detailed taxonomy of noncanonical uses of interrogative sentences, i.e. when they are used not to ask a question but to convey some information, or to ask a question albeit not that expressed by the interrogative sentence exploited in the act, to identify properties of circumstances where an interrogative sentence is being used in this way, and to propose some maxims that govern the rational use of questions. Four main categories of (...) such cases are presented, and a few further subclasses are differentiated. I show how these types are interrelated, and what logical features differentiate them. I also propose a hypothesis for when an interrogative sentence is not being used in its primary mode. Studies on circumstances in which questions are used in other ways can shed light on maxims that govern asking and questioning in a rational conversation; therefore, some possible maxims of this kind are proposed.

Even as philosophers increasingly apply their analytical acumen to other subjects of intellectual study, technology is one area relegated to the sidelines. To help dispel such prejudice, this exercise in applied ontology explains why technology invites critical examination, enumerates the generic needs and perceived wants that it fulfills, and then supplies a taxonomy of technological devices individuated in terms of the functional roles that their designers or consumers intend for them. In light of the classificatory scheme developed, I conclude (...) that everything in space and time may be used to realize technological goals, necessitating a more inclusive understanding of technology and thereby a heightened awareness of its pervasive character.

We provide a full characterization of computational error states for information systems. The class of errors considered is general enough to include human rational processes, logical reasoning, scientific progress and data processing in some functional programming languages. The aim is to reach a full taxonomy of error states by analysing the recovery and processing of data. We conclude by presenting machine-readable checking and resolve algorithms.

In this paper, we discern different types of possible relations. We focus on the distinction between internal and external relations and their various possible sub-types. In the first section, we present what is nowadays more or less the standard distinction between internal and external relations. In the second section, we make two contributions to the literature of internal relations: a new taxonomy of internal relations and a novel distinction between formal and material ontological relations. In the third section, we (...) discuss three distinctions among external relations, in particular the distinction between relata-specific and relata-unspecific relations. We argue that relata-specific external relations are a promising but incomplete solution to the vexed problem of Bradley’s relation regress. (shrink)

Taxonomy and terminology might seem like dull topics. But the diverse ways that eighteenth-century philosophers identified and classified the emotions crucially shaped the approaches they took. This chapter traces the sources available to eighteenth-century British philosophers for naming and ordering the passions, lays out the main vocabulary and concepts used for description and analysis, including the notions of “reflection” and “sympathy,” and outlines the principles that organized explanation, such as the division of the passions into the pleasurable or painful, (...) and the selfish or social, as well as the role of “master passions.”.

While phenomenologists have paid little attention to mediated sociality, the situation has recently been changing owing to the increasing dependence of social life on digital media. Alfred Schutz’s social phenomenology has gathered preeminent attention among phenomenological traditions as it reveals the structure of face-to-face and other types of social relationships. Although Shanyang Zhao’s concept of “consociated contemporaries” provided a reference point for the Schutzian studies of mediated sociality, he discarded the phenomenological aspects of Schutz’s ideas. To replace Zhao’s trichotomy of (...) consociates, contemporaries, and consociated contemporaries with a more phenomenological taxonomy, this paper examines Schutz’s concepts of thou- and they-orientation. Emphasizing that my thou-orientation to you does not entail your thou-orientation to me and that the other-orientation is not always reciprocal, this paper argues that mediated sociality can be classified into five types: reciprocal thou-thou-orientation, reciprocal thou-they-orientation, reciprocal they-they-orientation, non-reciprocal thou-orientation, and non-reciprocal they-orientation. Reciprocal thou-they-orientation, such as the relationship between a streamer and viewers in online live streaming, is a form of sociality that has recently become conspicuous owing to high-speed and massive Internet communication. Finally, this paper adds some remarks on the implications for the phenomenological theory of online empathy. (shrink)

Background If trials of therapeutic interventions are to serve society's interests, they must be of high methodological quality and must satisfy moral commitments to human subjects. The authors set out to develop a clinical - trials compendium in which standards for the ethical treatment of human subjects are integrated with standards for research methods. Methods The authors rank-ordered the world's nations and chose the 31 with >700 active trials as of 24 July 2008. Governmental and other authoritative entities of the (...) 31 countries were searched, and 1004 English-language documents containing ethical and/or methodological standards for clinical trials were identified. The authors extracted standards from 144 of those: 50 designated as ‘core’, 39 addressing trials of invasive procedures and a 5% sample of the remainder. As the integrating framework for the standards we developed a coherent taxonomy encompassing all elements of a trial's stages. Findings Review of the 144 documents yielded nearly 15 000 discrete standards. After duplicates were removed, 5903 substantive standards remained, distributed in the taxonomy as follows: initiation, 1401 standards, 8 divisions; design, 1869 standards, 16 divisions; conduct, 1473 standards, 8 divisions; analysing and reporting results, 997 standards, four divisions; and post-trial standards, 168 standards, 5 divisions. Conclusions The overwhelming number of source documents and standards uncovered in this study was not anticipated beforehand and confirms the extraordinary complexity of the clinical trials enterprise. This taxonomy of multinational ethical and methodological standards may help trialists and overseers improve the quality of clinical trials, particularly given the globalisation of clinical research.

It is suggested that the relationship between visual attention and conscious visual experience can be simplified by distinguishing different aspects of both visual attention and visual experience. A set of principles is first proposed for any possible taxonomy of the processes involved in visual attention. A particular taxonomy is then put forward that describes five such processes, each with a distinct function and characteristic mode of operation. Based on these, three separate kinds—or possibly grades—of conscious visual experience can (...) be distinguished, each associated with a particular combination of attentional processes. (shrink)

The paper presents main conceptual distinctions underlying much of modern philosophical thinking about value. The introductory Section 1 is followed in Section 2 by an outline of the contrast between non-relational value and relational value. In Section 3, the focus is on the distinction between final and non-final value as well as on different kinds of final value. In Section 4, we consider value relations, such as being better/worse/equally good/on a par. Recent discussions suggest that we might need to considerably (...) extend traditional taxonomies of value relations. (shrink)

Many recent cognitive studies reveal that human cognition is inherently perceptual, sharing systems with perception at both the conceptual and the neural levels. This paper introduces Barsalou's theory of perceptual symbols and explores its implications for philosophy of science. If perceptual symbols lie in the heart of conceptual processing, the process of attribute selection during concept representation, which is critical for defining similarity and thus for comparing taxonomies, can no longer be determined solely by background beliefs. The analogous nature of (...) perceptual symbols and the spatial nature of intraconceptual relations impose new constraints on attribute selection. These constraints help people with different background beliefs select compatible attributes, which constitute a common "platform" for taxonomy comparison. (shrink)
