Taxonomies of living things and the methods used to produce them changed little with the institutionalization of evolutionary thinking in biology. Instead, the relationships expressed in existing taxonomies were merely reinterpreted as the result of evolution, and evolutionary concepts were developed to justify existing methods. I argue that the delay of the Darwinian Revolution in biological taxonomy has resulted partly from a failure to distinguish between two fundamentally different ways of ordering identified by Griffiths : classification and systematization. Classification consists (...) of ordering entities into classes, groups defined by the attributes of their members; in contrast, systematization consists of ordering entities into systems, more inclusive entities whose existence depends on some natural process through which their parts are related. Evolutionary, or phylogenetic, systematics takes evolutionary descent to be the natural process of interest in biological taxonomy. I outline a general framework for a truly phylogenetic systematics and examine some of its consequences. (shrink)

There are two competing conceptions of the nature and domain of ecological science in the popular and academic literature, an orthodox conception and a more expansive conception. The orthodox conception conceives ecology as a natural biological science distinct from the human social sciences. The more expansive conception views ecology as a science whose domain properly spans both the natural and social sciences. On the more expansive conception, non-traditional ecological disciplines such as ecological psychology , ecological anthropology and ecological economics may (...) legitimately be regarded as sub-disciplines of ecology, and the practitioners of such disciplines as ecologists. The orthodox-expansionist issue is significant both for the practice of ecology and for the self-identity of the philosophy of ecology. I argue in favour of the expansionist conception of ecology on general conceptual grounds, and by developing the case for one particular non-traditional ecological discipline, ecological psychology.

The essays by Allen et al and Peterson present a number of challenges to readers of this volume. For some, the theoretical framework for ecosystem management that is endorsed by the authors – a variant of what may be called the “ecosystem approach to ecosystem management ” – will be unfamiliar, and there.

En el presente artículo tratamos algunos de los desafíos que un constitucionalismo global tiene actualmente respecto a la consecución de una justicia cosmopolita: pluralismo jurídico más allá del monismo jurídico y cultural del Estado moderno, sociodiversidad e interculturalidad, y sostenibilidad socioecológica de los modos de vida legitimados jurídicamente. Para ello consideraremos cómo entiende la tradición escolástico-católica de la Modernidad temprana las exigencias de lo común que atraviesan todo fenómeno jurídico en la vida colectiva y entre los pueblos, atendiendo específicamente a (...) algunas contribuciones clave de Francisco Suárez. De otra parte, como contrapunto del humanismo escolástico católico trataremos la visión de la Modernidad liberal, la cual plantea un modelo racional unívoco y ahistórico de configuración tanto de las exigencias de justicia entre los pueblos, como del modo de propiedad, el cual se identifica con una única forma de propiedad individual desvinculada de las exigencias del bien común.

A cross-cultural survey experiment revealed a widespread tendency to rely on a rule’s letter over its spirit when deciding which acts violate the rule. This tendency’s strength varied markedly across (k = 15) field sites, owing to cultural variation in the impact of moral appraisals on judgments of rule violation. Compared to laypeople, legal experts were more inclined to disregard their moral evaluations of the acts altogether, and consequently exhibited more pronounced textualist tendencies. Finally, we evaluated a plausible mechanism for (...) the emergence of textualism: In a two-player coordination game, incentives to coordinate in the absence of communication reinforced participants’ adherence to rules’ literal meaning. Together, these studies (Ntotal = 5495) help clarify the origins and allure of textualism, especially in the law. Within heterogeneous communities in which members diverge in their moral appraisals involving a rule’s purpose, the rule’s literal meaning provides a clear focal point—an easily identifiable point of agreement enabling coordinated interpretation among citizens, lawmakers and judges.

How do people evaluate causal relationships? Do they just consider what actually happened, or do they also consider what could have counterfactually happened? Using eye tracking and Gaussian process modeling, we investigated how people mentally simulated past events to judge what caused the outcomes to occur. Participants played a virtual ball‐shooting game and then—while looking at a blank screen—mentally simulated (a) what actually happened, (b) what counterfactually could have happened, or (c) what caused the outcome to happen. Our findings showed (...) that participants moved their eyes in patterns consistent with the actual or counterfactual events that they mentally simulated. When simulating what caused the outcome to occur, participants moved their eyes consistent with simulations of counterfactual possibilities. These results favor counterfactual theories of causal reasoning, demonstrate how eye movements can reflect simulation during this reasoning and provide a novel approach for investigating retrospective causal reasoning and counterfactual thinking.

A growing body of research has examined how people judge the persistence of identity over time—that is, how they decide that a particular individual is the same entity from one time to the next. While a great deal of progress has been made in understanding the types of features that people typically consider when making such judgments, to date, existing work has not explored how these judgments may be shaped by normative considerations. The present studies demonstrate that normative beliefs do (...) appear to play an important role in people's beliefs about persistence. Specifically, people are more likely to judge that the identity of a given entity remains the same when its features improve than when its features deteriorate. Study 1 provides a basic demonstration of this effect. Study 2 shows that this effect is moderated by individual differences in normative beliefs. Study 3 examines the underlying mechanism, which is the belief that, in general, various entities are essentially good. Study 4 directly manipulates beliefs about essence to show that the positivity bias regarding essences is causally responsible for the effect. (shrink)

At least three different issues are commonly referred to by the term “the species problem”: one concerns the necessary properties of species, a second the processes responsible for the existence of species, and a third methods for inferring species limits. Solutions have recently been proposed to the first two problems, which are conceptual in nature (the third is methodological). The first equates species with metapopulation lineages and proposes that existence as a separately evolving metapopulation lineage be considered the only necessary (...) property of species. The second views the species category as a cluster concept and proposes that no single process or set of processes be considered necessary for the existence of species. Although these two solutions have been portrayed as being in conflict, they are, in fact, highly compatible. Moreover, the proposals in question clarify the problem concerning methods for inferring the limits of species, which has for a long time been confused with the problem concerning the necessary properties of species. Together these proposals provide the opportunity for biology to move beyond debates about the definition of the species category and focus on estimating the boundaries and numbers of species as well as studying the diverse processes involved in their origin and persistence.

An examination of the post-Darwinian history of biological taxonomy reveals an implicit assumption that the definitions of taxon names consist of lists of organismal traits. That assumption represents a failure to grant the concept of evolution a central role in taxonomy, and it causes conflicts between traditional methods of defining taxon names and evolutionary concepts of taxa. Phylogenetic definitions of taxon names (de Queiroz and Gauthier 1990) grant the concept of common ancestry a central role in the definitions of taxon (...) names and thus constitute an important step in the development of phylogenetic taxonomy. By treating phylogenetic relationships rather than organismal traits as necessary and sufficient properties, phylogenetic definitions remove conflicts between the definitions of taxon names and evolutionary concepts of taxa. The general method of definition represented by phylogenetic definitions of clade names can be applied to the names of other kinds of composite wholes, including populations and biological species. That the names of individuals (composite wholes) can be defined in terms of necessary and sufficient properties provides the foundation for a synthesis of seemingly incompatible positions held by contemporary individualists and essentialists concerning the nature of taxa and the definitions of taxon names.

There are inherent difficulties in a subject like chemistry particularly the notion of a chemical reaction. In this paper the difficulties are discussed from a teaching and learning perspective and from a history of chemistry perspective. Three teaching/learning studies of the incompleteness of the iron thiocyanate reaction in chemical equilibrium are reviewed and it is shown that a recent historical study of the iron thiocyanate reaction has the potential to challenge the interpretation of the incompleteness of the reaction. This establishes (...) a controversial context where students can be introduced to epistemic thinking, that is, how to interrogate chemistry data and form a conclusion which resonates with what we know about the nature of science. A curriculum suggestion for pre-service chemistry teachers is provided. (shrink)

This Brief presents an historical investigation into the reaction between ferric ions and thiocyanate ions, which has been viewed in different ways throughout the last two centuries. Historically, the reaction was used in chemical analysis and to highlight the nature of chemical reactions, the laws of chemistry, models and theories of chemistry, chemical nomenclature, mathematics and data analysis, and instrumentation, which are important ingredients of what one might call the nature of chemistry. Using the history of the iron thiocyanate reaction (...) as a basis, the book’s main objective is to explore how chemistry develops its own knowledge base; how it assesses the reliability of that base; and how some important tools of the trade have been brought to bear on a chemical reaction to achieve understanding, a worthwhile goal of any historical investigation.

Uncertainty, insecurity and vulnerability have become commonplace in contemporary societies. This article aims an interdisciplinary reflection on the social and political construction of fear in liquid modernity. Zygmunt Bauman, Leonidas Donskis, Martha Nussbaum, Hannah Arendt, Ulrich Beck, Boaventura de Sousa Santos, Bernard Henri-Levy and Umberto Eco are some of the authors that we will put into dialogue to better understand the multiple narratives of fear in an era deeply marked by destruction social certainties, the worsening of social inequalities, the logic (...) of predatory capitalism, the resurgence of nationalisms of exclusion, as well as ethnic-cultural particularisms, which move from xenophobic and racist discourses and, finally, new risks, such as ecological degradation and the pandemic COVID19, which currently plagues contemporary societies and domesticates social behaviors.

A review of the chemical education research literature suggests that the term constructivism is used in two ways: experience-based constructivism and discipline-based constructivism. These two perspectives are examined as an epistemology in relation to the teaching and learning of the concept of idealization in chemistry. It is claimed that experience-based constructivism is powerless to inform the origin of such concepts in chemistry and while discipline-based constructivism can admit such theoretical concepts as idealization it does not offer any unique perspectives that (...) cannot be obtained from other models. Chemical education researchers do not consistently appeal to constructivism as an epistemology or as a teaching/learning perspective and it is shown that, while it draws attention to worthwhile teaching/learning strategies, it cannot be considered as foundational to chemical education research and tends to be used more as an educational label than as an undergirding theory.

Mathematics is so common-place in modern physics and chemistry that one may not realise how controversial its admittance was to these fields in the eightieth and ninetieth centuries respectively. This paper deals with the controversy during the formation of physical chemistry as a discipline in the late ninetieth and early twentieth centuries and sketches more recent criticisms of the way mathematics has been used in solution chemistry. The controversy initially related particularly to electrolyte chemistry and its emerging use of mathematics (...) to support Arrhenius’ theory of ionic dissociation. The impact of mathematics on the field is divided into three phases: that from 1880 to 1920 which was a period of heightened controversy; that from 1920 to 1990 which was a period of relative calm and mathematical development; and finally, that from 1990 to the present which has been a time of reflective criticism of the extensive use of empirical parameters in the emergent mathematics of the twentieth century. It is argued that the current solution to the criticism, as proposed by Heyrovska, is best viewed in the light of the historical development of the controversy. (shrink)

Hoerl & McCormack propose a two-system account of temporal cognition. We suggest that, following other classic proposals where cognitive systems are putatively independent, H&M's two-system hypothesis should, at a minimum, involve a difference in the nature of the representations upon which each system operates, and a difference in the computations they carry out. In this comment we offer two challenges aimed at showing that H&M's proposal does not meet the minimal requirements and.

Ecological science has been viewed by some philosophers as a foundational resource for the development of metaphysical, epistemological and normative views concerning humanity’s relationship with the natural environment, or what might be called an “ecological philosophy.” Analysis of three attempts to infer philosophical conclusions from ecological science shows that (1) there are serious obstacles facing any attempt to derive unique philosophical consequences from ecological science and (2) the project of developing an ecological philosophy relevant to human-environment relations is seriously hindered (...) by a reliance on traditional ecological science that focuses on relations between nonhuman organisms and their environments. However, the search for an ecological philosophy is not inherently misguided because (1) although ecological science may never support a unique philosophical interpretation of ecological theory, empirical evidence can function to narrow the range of possible interpretations, which is a significant epistemic achievement; and because (2) there are several non-traditional branches of ecological science that focus on human-environment relations and that consequently may be better suited to function as conceptual resources for the sorts of problems that concern environmental philosophers.

Many physicians are involved in relationships that create tension between a physician's duty to work in her patients’ best interest at all times and her financial arrangement with a third party, most often a pharmaceutical manufacturer, whose primary goal is maximizing sales or profit. Despite the prevalence of this threat, in the United States and globally, the most common reaction to conflicts of interest in medicine is timid acceptance. There are few calls for conflicts of interest to be banned, and, (...) to our knowledge, no one calls for conflicted practitioners to be reprimanded. Contrast our attitudes in medicine with public attitudes toward financial conflicts among government employees. When enforcement of rules against conflict of interest slackens in the public sector, news organizations investigate and publish their criticism. Yet even when doctors are quoted in the media promoting specific drugs, their personal financial ties to the drug maker are rarely mentioned. Policies for governmental employees are strict, condemnation is strong, and criminal statutes exist (allowing for corruption charges). Yet the evidence that conflict is problematic is, if anything, stronger in medicine than in the public sector. Policies against conflicts of interest in medicine should be at least as strong as those already existing in the public sector. (shrink)

This article will investigate the issue of accessing benxin 本心 (original mind), subsequent operation from Self and, in that process, union with the greater universe or benti 本体 (original substance)—a state expressed in the West as cosmic consciousness. It is proposed that this allows one to participate as a partner in the creative process of one’s own life and the surrounding world. The equally important question of how to gain contact with original mind will also be addressed, as well as (...) the consequences of doing so with regard to the human condition. The concept of original thought is introduced, being important here as it is held to be that thought which is generated in the pure condition of original mind, devoid of influence from finite physical existence.

Temporary international mobility is an increasingly relevant practice amongst academics. However, current literature lacks understanding on whether such mobility influences the individual academics’ entrepreneurial knowledge. This paper hypothesizes that temporary international academic mobility is conducive to the academic’s entrepreneurial knowledge and that interpersonal social networks play a crucial role in the transfer of this knowledge through their strength and size properties. We perform a Partial Least Squares - Structural Equation Model and build upon an original survey data set collected amongst (...) 281 Chinese academics. We find that the size of one’s interpersonal social network fully mediates the relationship between international academic mobility and entrepreneurial knowledge. This result points to the importance of a structurally broad - rather than a relationally strong - international social network in the academic’s accumulation of entrepreneurial knowledge abroad.

In order to make strategic decisions and improve their firm’s performance, top management teams must have information on the competitive context in general, and the firm’s competitors in particular. During the decision-making process, top managers can have access to “privileged information”—i.e., information of a confidential and potentially strategic nature that could ultimately confer a decisional advantage over competing parties. However, obtaining and using privileged information in a business context is often illegal—and if not, is usually deemed unethical or “against the (...) rules.” Using a quasi-experimental design, this study explores the reasons why an individual might engage in such unethical behavior. We assess the extent to which managers use privileged information with respect to perceived team cohesion and peers’ ethicality. More specifically, our results show that the use of privileged information is predicted by the decision-maker’s perceptions of their team cohesion and their peers’ ethicality. Moreover, we find that team performance, as a group-level nonself-reported factor, moderates the relationship between cohesion and the use of privileged information. The relationship between cohesion, ethical behavior, and team performance is also discussed. We draw on these findings to make some practical suggestions on how to incorporate practices that could better prevent the unethical use of privileged information in strategic decision-making processes.

Ernst Mayr played a central role in the establishment of the general concept of species as metapopulation lineages, and he is the author of one of the most popular of the numerous alternative definitions of the species category. Reconciliation of incompatible species definitions and the development of a unified species concept require rejecting the interpretation of various contingent properties of metapopulation lineages, including intrinsic reproductive isolation in Mayr's definition, as necessary properties of species. On the other hand, the general concept (...) of species as metapopulation lineages advocated by Mayr forms the foundation of this reconciliation, which follows from a corollary of that concept also advocated by Mayr: the proposition that the species is a fundamental category of biological organization. Although the general metapopulation lineage species concept and Mayr's popular species definition are commonly confused under the name "the biological species concept," they are more or less clearly distinguished in Mayr's early writings on the subject. Virtually all modern concepts and definitions of the species category, not only those that require intrinsic reproductive isolation, are to be considered biological according to the criterion proposed by Mayr. Definitions of the species category that identify a particular contingent property of metapopulation lineages (including intrinsic reproductive isolation) as a necessary property of species reduce the number of metapopulation lineages that are to be recognized taxonomically as species, but they cause conflicts among alternative species definitions and compromise the status of the species as a basic category of biological organization.

This research analyzes the theoretical answer received by one of the factors that cause the so-called Price Revolution in Europe during the 16th and 17th centuries, specifically the aspect related to the alterations in the monetary values ​​of pieces of vellón and silver in Castile and England. In both countries, these episodes were rigorously analyzed from a theoretical point of view, as can be seen from the study of the monetary ideas of the period that were developed in these territories. (...) In this study, in light of the historical events that took place, we analyze the foundations of the monetary thought of Juan de Mariana and John Locke who oppose the the alteration of money by the sovereign for fiscal reasons, as well as their different reception.

_Media and Migration: Learning in a globalized wor_ld brings together studies located at the intersection of migration, media and learning, and considers how the learning practices of youth in migration are shaped by new media. The change in the mobilities of people, media, and material goods which allow new connections between 'global' and 'local' life has had a significant impact on contemporary migration, as well as social life more generally. The contributors to this book show how learning trajectories of individual (...) learners become defined by broadly distributed networks and knowledge systems. Learning in stable, closed, and culturally uniform settings is becoming the exception rather than the norm. While immigrant youth are often associated with juggling multiple lives or worlds, such juggling is increasingly becoming typical for all youth living with new media. The book therefore addresses youth learning more generally in relation to media, globalization, and diversity, as well as the digital learning practices of immigrants and non-immigrants. This book was originally published as a special issue of _Learning, Media and Technology. _. (shrink)

James Franklin has argued that the formal, mathematical sciences of complexity — network theory, information theory, game theory, control theory, etc. — have a methodology that is different from the methodology of the natural sciences, and which can result in a knowledge of physical systems that has the epistemic character of deductive mathematical knowledge. I evaluate Franklin’s arguments in light of realistic examples of mathematical modelling and conclude that, in general, the formal sciences are no more able to guarantee certainty (...) than the natural sciences. Yet the formal sciences are characterized by a ‘domain-independence’ that is philosophically interesting, and I argue that it is this property that Franklin actually employs to distinguish the formal from the natural sciences. I use Einstein’s ‘principle’/‘constructive’ theory distinction to contrast the domain-independence of physical theories with the domain-independence of formal mathematical theories, and show how both kinds of domain-independence function to generate the domain-independence that is observed in the complex systems sciences. © 1999 Elsevier Science Ltd.

Advocates of cladistic parsimony methods have invoked the philosophy of Karl Popper in an attempt to argue for the superiority of those methods over phylogenetic methods based on Ronald Fisher's statistical principle of likelihood. We argue that the concept of likelihood in general, and its application to problems of phylogenetic inference in particular, are highly compatible with Popper's philosophy. Examination of Popper's writings reveals that his concept of corroboration is, in fact, based on likelihood. Moreover, because probabilistic assumptions are necessary (...) for calculating the probabilities that define Popper's corroboration, likelihood methods of phylogenetic inference—with their explicit probabilistic basis—are easily reconciled with his concept. In contrast, cladistic parsimony methods, at least as described by certain advocates of those methods, are less easily reconciled with Popper's concept of corroboration. If those methods are interpreted as lacking probabilistic assumptions, then they are incompatible with corroboration. Conversely, if parsimony methods are to be considered compatible with corroboration, then they must be interpreted as carrying implicit probabilistic assumptions. Thus, the non-probabilistic interpretation of cladistic parsimony favored by some advocates of those methods is contradicted by an attempt by the same authors to justify parsimony methods in terms of Popper's concept of corroboration. In addition to being compatible with Popperian corroboration, the likelihood approach to phylogenetic inference permits researchers to test the assumptions of their analytical methods (models) in a way that is consistent with Popper's ideas about the provisional nature of background knowledge.
