This dissertation is a collection of three papers – “Knowing Oneself for Others,” “Stereotype Threat and the Value of Self-Knowledge,” and “Self-Knowledge, Epistemic Work, and Injustice” – in which I address the connections between self-knowledge production and social inequality. I explain, using a variety of contemporary political and cultural examples, that marginalized individuals are more likely to be required to know certain things about themselves than socially privileged individuals, especially about those aspects of their lives and identities which are essential (...) to their being marginalized. I argue that this should make us rethink our basic understanding of epistemic injustice, which is typically thought of as involving the prevention of marginalized individuals from producing knowledge. More specifically, in “Knowing Oneself for Others,” I introduce the notion of “compulsory self-disclosure,” a social phenomenon in which an individual is forced to reveal things about themselves, often in ways that further contribute to their oppression. “Stereotype Threat and the Value of Self-Knowledge” addresses how self-ignorance can actually be desirable for individuals facing stereotype threat, and I argue that treating stereotype threat as an epistemic injustice issue can actually harm rather than help individuals in certain cases. Finally, in “Self-Knowledge, Epistemic Work, and Injustice,” I assess the reasoning behind the assumption that marginalized people are self-ignorant; I argue that we need to appreciate the central role that epistemic work plays in self-knowledge production to understand why the standard assumption about marginalized self-ignorance is misguided. Ultimately, I would have us think of self-knowledge production as not just epistemic work but as work that is often emotionally difficult and even metaphysically transformative – coming to have self-knowledge in certain ways can quite literally change who you are. In light of this, the overarching aim of this work is to argue for there being an inextricable link between an individual’s knowledge of themselves and their social status, as well as to discourage readers from thinking of the production of self-knowledge as inherently desirable or as a wholly epistemic issue.

Previous studies have been split over how to view family owners’ CSR engagement, arguing that they either engage in or disengage from CSR based on different motives (i.e., preserving socio-emotional wealth vs. seeking rent expropriation). Focusing on family owners in business groups, this study integrates these divergent views. We hypothesize that family owners would pursue both motives simultaneously by optimizing the level of CSR of each affiliated firm depending on their ownership level. Furthermore, we argue that this tendency is moderated (...) by group-level contexts. Using a sample of Korean business groups, we found that family ownership is negatively associated with affiliated firms’ CSR. Also, this negative relationship is more pronounced when firms belong to business groups with more charitable corporate foundations and when business networks are greater in their scope and scale. This study contributes to the literature by offering a more complete understanding of how family owners make CSR decisions in business group contexts. (shrink)

Urban streetscapes are outdoor areas in which the general public can appreciate green landscapes and engage in outdoor activities along the street. This study tested the extent to which the degree of awareness of urban street trees impacts attention restoration and perceived restorativeness. We manipulated the degree of awareness of street trees. Participants were placed into four groups and shown different images: (a) streetscapes with absolutely no trees; (b) streetscapes with flashes of trees in which participants had minimal awareness of (...) the content; (c) streetscapes with trees; and (d) streetscapes with trees to which participants were told to pay attention. We compared the performance of 138 individuals on measures of attention and their evaluations of perceived restorativeness. Two main findings emerged. First, streetscapes with trees improved the performance of participants on attentional tests even without their awareness of the trees. Second, participants who had raised awareness of street trees performed best on the attentional test and rated the streetscapes as being more restorative. These findings enhance our knowledge about the role of an individual's awareness of restorative elements and have implications for designers and individuals who are at risk of attentional fatigue.

The history of biological systematics documents a continuing tension between classifications in terms of nested hierarchies congruent with branching diagrams (the ‘Tree of Life’) versus reticulated relations. The recognition of conflicting character distribution led to the dissolution of the scala naturae into reticulated systems, which were then transformed into phylogenetic trees by the addition of a vertical axis. The cladistic revolution in systematics resulted in a representation of phylogeny as a strictly bifurcating pattern (cladogram). Due to the ubiquity of (...) character conflict—at the genetic or morphological level, or at any level in between—some characters will necessarily have to be discarded ( qua noise) in favor of others in support of a strictly bifurcating phylogenetic tree. Pattern analysts will seek maximal congruence in the distribution of characters (ultimately of any kind) relative to a branching tree-topology; process explainers will call such tree-topologies into question by reference to incompatible evolutionary processes. Pattern analysts will argue that process explanations must not be brought to bear on pattern reconstruction; process explainers will insist that the reconstructed pattern requires a process explanation to become scientifically relevant, i.e., relevant to evolutionary theory. The core question driving the current debate about the adequacy of the ‘Tree of Life’ metaphor seems to be whether the systematic dichotomization of the living world is an adequate representation of the complex evolutionary history of global biodiversity. In ‘Questioning the Tree of Life’, it seems beneficial to draw at least four conceptual distinctions: pattern reconstruction versus process explanation as different epistemological approaches to the study of phylogeny; open versus closed systems as expressions of different kinds of population (species) structures; phylogenetic trees versus cladograms as representations of evolutionary processes versus patterns of relationships; and genes versus species as expressions of different levels of causal integration and evolutionary transformation.

We show that both Rado's Conjecture and strong Chang's Conjecture imply that there are no special ℵ2-Aronszajn trees if the Continuum Hypothesis fails. We give similar result for trees of higher heights and we also investigate the influence of Rado's Conjecture on square sequences.

We prove that there are groups in the constructible universe whose automorphism towers are highly malleable by forcing. This is a consequence of the fact that, under a suitable diamond hypothesis, there are sufficiently many highly rigid non-isomorphic Souslin trees whose isomorphism relation can be precisely controlled by forcing.

Previous work employing graph theory and nonlinear analysis has found increased spatial and temporal disorder, respectively, of functional brain connectivity in schizophrenia. We present a new method combining graph theory and nonlinear techniques that measures the temporal disorder of functional brain connections. Multichannel electroencephalographic data were windowed and functional networks were reconstructed using the minimum spanning trees of correlation matrices. Using a method based on Shannon entropy, we found elevated connection entropy in gamma activity of patients with schizophrenia; however, gamma (...) connection entropy remained elevated in patients with schizophrenia even after a reduction in symptoms due to treatment with antipsychotics. Our results are consistent with several possibilities: aberrant functional connectivity is epiphenomenal to schizophrenia, aberrant functional connectivity is a central feature but antipsychotics reduce symptoms by an independent mechanism, or connection entropy is not an appropriately sensitive measure of brain abnormalities in schizophrenia.

There is a need for person-centred approaches and empowerment of staff within the residential care for older people; a movement called ‘culture change’. There is however no single path for achieving culture change. With the aim of increasing understandings about cultural change processes and the promotion of cultural values and norms associated with person-centred practices, this article presents an action research project set on a unit in the Netherlands providing care for older people with dementia. The project is presented as (...) a case study. This study examines what has contributed to the improvement of participation of older people with dementia in daily occupational and leisure activities according to practitioners. Data was collected by participant observation, interviews and focus groups. The results show that simultaneous to the improvement of the older people’s involvement in daily activities a cultural transformation took place and that the care became more person-centred. Spontaneous interactions and responses rather than planned interventions, analysis and reflection contributed to this. Furthermore, it proved to be beneficial that the process of change and the facilitation of that process reflected the same values as those underlying the cultural change. It is concluded that changes arise from dynamic, interactive and non-linear processes which are complex in nature and difficult to predict and to control. Nevertheless, managers and facilitators can facilitate such change by generating movement through the introduction of small focused projects that meet the stakeholders’ needs, by creating conditions for interaction and sense making, and by promoting the new desired cultural values.

"The Natural System" is the name given to the underlying arrangement present in the diversity of life. Unlike a classification, which is made up of classes and members, a system or arrangement is an integrated whole made up of connected parts. In the pre-evolutionary period a variety of forms were proposed for the Natural System, including maps, circles, stars, and abstract multidimensional objects. The trees sketched by Darwin in the 1830s should probably be considered the first genuine evolutionary diagrams of (...) the Natural System—the first genuine evolutionary trees. Darwin refined his image of the Natural System in the well-known evolutionary tree published in the Origin of Species, where he also carefully distinguished between arrangements and classifications. Following the publication of the Origin, there was a great burst of evolutionary tree building, but interest in trees declined substantially after 1900, only to be revived in recent years with the development of cladistic analysis. ¶ While evolutionary trees are modern diagrams of the Natural System, they are at the same time instances of another broad class of diagrams that may be called "trees of history": branching diagrams of genealogical descent and change. During the same years that Darwin was sketching his first evolutionary trees, the earliest examples of two other trees of history also appeared: the first trees of language evolution and of manuscript genealogy. Though these were apparently independent of evolutionary trees in their origin, the similarities among all these trees of history, and among the historical processes that underlie them, were soon recognized. Darwin compared biological evolution and language evolution several times in the Origin of Species, and both Ernst Haeckel and the linguist August Schleicher made similar comparisons. Both linguists and stemmaticists (students of manuscript descent) understood the principle of apomorphy—the principle that only shared innovations provide evidence of common ancestry—more clearly than did systematists, and if there had been more cross-fertilization among these fields the cladistic revolution in systematics might well have taken place in the nineteenth century. ¶ Although historical linguists and stemmaticists have in some respects had sounder theory than have systematists, at least until recently, they have also had the practical problem of very large amounts of data, a problem not often faced by systematists until the advent of molecular sequencing. The opportunity now exists for systematists to contribute to the theory and practice of linguistics and stemmatics, their sister disciplines in historical reconstruction, through application of our commonly used computer programs for tree estimation. Preliminary results from the application of numerical cladistic analysis to a large stemmatic data set have been very encouraging, and have already generated much discussion in the stemmatics community.

Originally published in 1972, Should Trees Have Standing? was a rallying point for the then burgeoning environmental movement, launching a worldwide debate on the basic nature of legal rights that reached the U.S. Supreme Court. Now, in the 35th anniversary edition of this remarkably influential book, Christopher D. Stone updates his original thesis and explores the impact his ideas have had on the courts, the academy, and society as a whole. At the heart of the book is an eminently sensible, (...) legally sound, and compelling argument that the environment should be granted legal rights. For the new edition, Stone explores a variety of recent cases and current events--and related topics such as climate change and protecting the oceans--providing a thoughtful survey of the past and an insightful glimpse at the future of the environmental movement. This enduring work continues to serve as the definitive statement as to why trees, oceans, animals, and the environment as a whole should be bestowed with legal rights, so that the voiceless elements in nature are protected for future generations.

Phylogenies are increasingly prominent across all of biology, especially as DNA sequencing makes more and more trees available. However, their utility is compromised by widespread misconceptions about what phylogenies can tell us, and improved tree thinking is crucial. The most-serious problem comes from reading trees as ladders from left to right - many biologists assume that species-poor lineages that appear early branching or basal are ancestral - we call this the primitive lineage fallacy. This mistake causes misleading inferences about (...) changes in individual characteristics and leads to misrepresentation of the evolutionary process. The problem can be rectified by considering that modern phylogenies of present-day species and genes show relationships among evolutionary cousins. Emphasizing that these are extant entities in the 21st century will help correct inferences about ancestral characteristics, and will enable us to leave behind 19th century notions about the ladder of progress driving evolution.

The Tree of Nature represents an IT-based approach to understanding Nature in the light of present-day scientific knowledge. The universe, in this view, consists of discrete entities; these are not material particles, however, but information processing events that produce observable changes in the world. The surprising result of this analysis is that the workings of Nature are based on a decision tree consisting of two dozen parameters. The tree is similar to the evolutionary phylogenetic system of the (...) various forms of life, but it is far more fundamental; constituting, as it does, the very base of everything that exists. The overall conclusion is that the universe is steadily producing new information. Metaphorically speaking, it constitutes a self-unfolding story in which events do not pass away into non-existence but instead remain forever as an indelible part of the whole. This also holds true for integrated sets of events, such as the lifetime experiences of an individual. The Tree of Nature leads to the following testable prediction: A successful quantum-gravity theory will involve the notion of a strong complementarity between gravity and the strong nuclear force.

The article discusses how current mediated conditions change nature perception from a media study perspective. The article is based on different case studies such as the current sensation of atmospheric change through sensible media attached to trees which get published via Twitter, the meteorologist Amazonian Tall Tower Observatory and the use of gutta percha derived from tropical trees for the production of cables in the history of telegraphy. For analysing the examples, the perspective of »media as environments« is flipped to (...) »environments as media«, because this focus doesn’t approach media from a networked and technological perspective primarily but makes productive the elemental character of basic »media« like air, earth and water.

This project explores the extent to which trees can be seen as a solution to global environmental crisis. The physical component of this project involved growing over 300 fruit trees from seed and planting them throughout Mora county, Costa Rica. This report represents the theoretical component of the project, in which the author reflects on the lessons that can be drawn from the act of planting a tree, in order to add complexity to what is often used as cultural (...) shorthand for an uncontroversial environmental virtue. Originally conceived as an opportunity to offset the author’s carbon emissions from a lifetime of airline travel, an examination of the literature reveals the practical ambiguity of this short-term goal. The author concludes that while trees do provide many physical benefits for their surrounding microclimate, including their ability to promote the flow of water, air and carbon, they cannot address our planetary crisis without larger cultural change. The metaphors that trees convey may therefore be just as vital as the physical services they provide. Among these are the necessity of addressing the root causes of environmental crisis, how small microclimatic changes create resilient plant communities, and the way planting a seed offers an alternative to the insatiable search for an action that is “good enough” to save the planet.

Change is one of experience's most evident data. The man who has finished reading is different from the same man before he started; the book he has read was once a tree. But if the fact is clear, it hides a very profound problem. Examining change, we see from experience that things do not come to be out of nothing; other things turn into them. The principle of sufficient reason confirms this, since a pure negation can never be a (...) sufficient reason for anything. But if this is true, then neither can the negation of an attribute provide a sufficient reason for its emergence in an already existing thing; this would be tantamount to saying that the attribute came from nothing. Nor, if the thing really changes, can we say simply that an external agent "pours in" some of its perfection, since then it would not change, but only receive a metaphysical coat of paint. And so, we seem to have forced ourselves into a dilemma: things must be what they are, and yet they must themselves be in some sense what they are not. If we deny the first part there is nothing to change; if the second, change is unintelligible, and hence impossible. (shrink)

Changing the information format from probabilities into frequencies as well as employing appropriate visualizations such as tree diagrams or 2 × 2 tables are important tools that can facilitate people’s statistical reasoning. Previous studies have shown that despite their widespread use in statistical textbooks, both of those visualization types are only of restricted help when they are provided with probabilities, but that they can foster insight when presented with frequencies instead. In the present study, we attempt to replicate this (...) effect and also examine, by the method of eye tracking, why probabilistic 2 × 2 tables and tree diagrams do not facilitate reasoning with regard to Bayesian inferences (i.e., determining what errors occur and whether they can be explained by scan paths), and why the same visualizations are of great help to an individual when they are combined with frequencies. All ten inferences of N = 24 participants were based solely on tree diagrams or 2 × 2 tables that presented either the famous “mammography context” or an “economics context” (without additional textual wording). We first asked participants for marginal, conjoint, and (non-inverted) conditional probabilities (or frequencies), followed by related Bayesian tasks. While solution rates were higher for natural frequency questions as compared to probability versions, eye-tracking analyses indeed yielded noticeable differences regarding eye movements between correct and incorrect solutions. For instance, heat maps (aggregated scan paths) of distinct results differed remarkably, thereby making correct and faulty strategies visible in the line of theoretical classifications. Moreover, the inherent structure of 2 × 2 tables seems to help participants avoid certain Bayesian mistakes (e.g., “Fisherian” error) while tree diagrams seem to help steer them away from others (e.g., “joint occurrence”). We will discuss resulting educational consequences at the end of the paper. (shrink)

The anthropogenic environmental change characteristic of the Anthropocene generates numerous threats and opportunities for the non-human beings who are intrinsic to forest and tree health. There are profound consequences for both humans and non-humans as a result of natural ecosystem disturbances, such as forest fires or invasive insects, and their accompanying environmental management responses. However, the consequences for non-humans as a result of either disturbance or management receive virtually no attention within environmental policy and practice. In this paper we (...) argue for the growth and transformation – the ‘eclosion’ – of the ‘stakeholder’ concept so as to provide a pragmatic basis for greater attentiveness to, and comprehension of, non-human interest. We explore the implications and feasibility of this, describing particular approaches to stakeholder analysis and representation that emanate from research methods including multispecies ethnography and studies in ‘new animism’, that can effectively enable non-human ‘voices’ to be heard and taken more seriously. We conclude there are solid methodological and conceptual foundations on which to build an effective understanding of non-human stake-holdership, particularly in the area of forest and tree health.

The "tree of life" iconography, representing the history of life, dates from at least the latter half of the 18th century, but evolution as the mechanism providing this bifurcating history of life did not appear until the early 19th century. There was also a shift from the straight line, scala naturae view of change in nature to a more bifurcating or tree-like view. Throughout the 19th century authors presented tree-like diagrams, some regarding the Deity as the mechanism (...) of change while others argued for evolution. Straight-line or anagenetic evolution and bifurcating or cladogenetic evolution are known in biology today, but are often misrepresented in popular culture, especially with anagenesis being confounded with scala naturae. Although well known in the mid 19th century, the geologist Edward Hitchcock has been forgotten as an early, if not the first author to publish a paleontologically based "tree of life" beginning in 1840 in the first edition of his popular general geology text Elementary Geology. At least 31 editions were published and those between 1840 and 1859 had this "paleontological chart" showing two trees, one for fossil and living plants and another for animals set within a context of geological time. Although the chart did not vary in later editions, the text explaining the chart did change to reflect newer ideas in paleontology and geology. Whereas Lamarck, Chambers, Bronn, Darwin, and Haeckel saw some form of transmutation as the mechanism that created their "trees of life," Hitchcock, like his contemporaries Agassiz and Miller, who also produced "trees of life," saw a deity as the agent of change. Through each edition of his book Hitchcock denounced the newer transmutationist hypotheses of Lamarck, then Chambers, and finally Darwin in an 1860 edition that no longer presented his tree-like "paleontological chart.".

The Tree of Life has traditionally been understood to represent the history of species lineages. However, recently researchers have suggested that it might be better interpreted as representing the history of cellular lineages, sometimes called the Tree of Cells. This paper examines and evaluates reasons offered against this cellular interpretation of the Tree of Life. It argues that some such reasons are bad reasons, based either on a false attribution of essentialism, on a misunderstanding of the problem (...) of lineage identity, or on a limited view of scientific representation. I suggest that debate about the Tree of Cells and other successors to the traditional Tree of Life should be formulated in terms of the purposes these representations may serve. In pursuing this strategy, we see that the Tree of Cells cannot serve one purpose suggested for it: as an explanation for the hierarchical nature of taxonomy. We then explore whether, instead, the tree may play an important role in the dynamic modeling of evolution. As highly-integrated complex systems, cells may influence which lineage components can successfully transfer into them and how they change once integrated. Only if they do in fact have a substantial role to play in this process might the Tree of Cells have some claim to be the Tree of Life. (shrink)

Radial growth has long been a subject of interest in tree biology research. Recent studies have brought a significant change in the understanding of some basic processes characteristic to the vascular cambium, a meristem that produces secondary vascular tissues (phloem and xylem) in woody plants. A new hypothesis regarding the mechanism of intrusive growth of the cambial initials, which has been ratified by studies of the arrangement of cambial cells, negates the influence of this apical cell growth on the (...) expansion of the cambial circumference. Instead, it suggests that the tip of the elongating cambial initial intrudes between the tangential (periclinal) walls, rather than the radial (anticlinal) walls, of the initial(s) and its(their) derivative(s) lying ahead of the elongating cell tip. The new concept also explains the hitherto obscure mechanism of the cell event called ‘elimination of initials’. This article evaluates these new concepts of the cambial cell dynamics and offers a new interpretation for some curious events occurring in the cambial meristem in relation to the radial growth in woody plants.

Tree diagrams are the prevailing form of visualization in biological classification and phylogenetics. Already during the time of the so-called Systematist Wars from the mid-1960s until the 1980s most journal articles and textbooks published by systematists contained tree diagrams. Although this episode of systematics is well studied by historians and philosophers of biology, most analyses prioritize scientific theories over practices and tend to emphasize conflicting theoretical assumptions. In this article, I offer an alternative perspective by viewing the conflict (...) through the lens of representational practices with a case study on tree diagrams that were used by numerical taxonomists (phenograms) and cladists (cladograms). I argue that the current state of molecular phylogenetics should not be interpreted as the result of a competition of views within systematics. Instead, molecular phylogenetics arose independently of systematics and elements of cladistics and phenetics were integrated into the framework of molecular phylogenetics, facilitated by the compatibility of phenetic and cladistic practices with the quantitative approach of molecular phylogenetics. My study suggests that this episode of scientific change is more complex than common narratives of battles and winners or conflicts and compromises. Today, cladograms are still used and interpreted as specific types of molecular phylogenetic trees. While phenograms and cladograms represented different forms of knowledge during the time of the Systematist Wars, today they are both used to represent evolutionary relationships. This indicates that diagrams are versatile elements of scientific practice that can change their meaning, depending on the context of use within theoretical frameworks. (shrink)

Most models of rational action assume that all possible states and actions are pre-defined and that preferences change only when beliefs do. But several decision and game problems lack these features, calling for a dynamic model of preferences: preferences can change when unforeseen possibilities come to light or when there is no specifiable or measurable change in belief. We propose a formally precise dynamic model of preferences that extends an existing static model. Our axioms for updating preferences preserve consistency while (...) minimising change, like Hansson’s :1–28, 1995). But unlike prior models of preference change, ours supports default reasoning with partial preference information, which is essential to handle decision problems where the decision tree isn’t surveyable. We also show that our model avoids problems for other models of preference change discussed in Spohn. (shrink)

Genetic modification of trees has the potential to change our forests forever, yet there has been little publicly available information or debate on this important topic. Ethical analysis of genetic modification of plants to date has been focussed mainly on food and feed crops and pharmaceutical production. The purpose of this paper is to examine one major ethical issue arising in connection with the genetic modification of trees, the necessity to examine the practice in its full scientific, social, economic, political (...) and environmental context. It is argued that if this is not done, important factors that play a role in a through ethical critique will be overlooked. The analysis focuses mainly on the Canadian situation, but there are implications for other timber-producing nations as well. The paper concludes that a thorough ethical critique must take into account the ends for which biotechnology is being pursued. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Change of Perspective in Ovid, Metamorphoses 12.11-23Margaret Worsham MusgroveIn the first of the trojan stories which dominate Metamorphoses books 12 and 13, Ovid recounts a well-known Homeric episode, the omen of the snake at Aulis; a snake climbs into a tree and eats a nestful of eight baby birds plus their mother. According to Calchas' interpretation, this omen symbolized the nine years the Greeks would besiege Troy before (...) taking it in the tenth, and is recalled for the despairing Greek army by Odysseus at Iliad 2.299-329. Ovid's version follows the Homeric story closely, with several verbal parallels. But readers of the Metamorphoses may also see another intertext, the second book of Vergil's Aeneid, Aeneas' account of the fall of Troy, the same event to which the omen looks forward.1 By playing on his readers' knowledge of the Aeneid, Ovid introduces a competing voice into his version, while ostensibly retaining the familiar Homeric story. The present paper will discuss how this intertext is activated to influence our reading of Ovid's "Iliad."2That Ovid's readers might hear Vergilian echoes in a reference to the fall of Troy should not be unexpected. In Vergil's Aeneid, the Trojan War and its aftermath had been transformed into a Trojan experience, seen through Trojan eyes. In the Iliadic section of Ovid's post-Vergilian epic, Ovid must balance his Greek-centered stories, told in greatly condensed form, with the expectations of his Roman readers. By alluding to [End Page 267] the other side of the war, Ovid is able to restore some of the layers of complexity which his brevity has removed from his Greek models, and to remind his readers of the problematic nature of victory and conquest, as Vergil had done. In the process, Ovid shows himself to be an extremely close reader of both Homer and Vergil; his use of the two of them together in this episode can even help elucidate the relationship between his two great epic predecessors.Ovid and HomerOvid's account of the omen nearly parallels Odysseus' speech in Homer; Ovid is more compact, but agrees with Homer in many respects. The visual perspective of both passages is emphatically Greek. In Homer, the story is told by an eyewitness, Odysseus, who reminds the Greek army that they had all observed the omen:(Iliad 2.301-2)Ovid, although telling the story in his own, or "first-level," narrative voice, notes that "the Greeks saw" the omen: Danai videre (Met. 12.13). In both scenes, the snake appears suddenly at a sacrifice and creeps into a plane-tree near the altar.(Iliad 2.305-10)hic patrio de more Iovi cum sacra parassent, ut vetus accensis incanduit ignibus ara, serpere caeruleum Danai videre draconem in platanum, coeptis quae stabat proxima sacris.(Met. 12.11-14)Ovid's specification that the sacrifice was being made to Jupiter illustrates an efficient technique of condensation. Although Homer says the sacrifice was generally "to the immortals" (athanatoisi, Iliad 2.306), the snake was sent by Zeus, who is also credited with its metamorphosis [End Page 268] (Iliad 2.309, 318). The presence of Zeus is necessary for the prophetic function of the snake, in Kirk's words (1985, ad Iliad 2.307-18), "since only he could determine or recognize in advance the outcome of the war." Ovid allows time for only one mention of a divinity in this scene, but includes the one deity crucial to the Homeric episode.3 When Ovid introduces the birds, every element of his sentence can be paralleled in Homer's lines:(Iliad 2.311-13)nidus erat volucrum bis quattuor arbore summa(Met. 12.15)Both Homer and Ovid place the verb "be" near the beginning of the line, followed by words for the birds themselves; both note the birds' location (the top of the tree) and number (eight, for the moment). Thus Ovid sets the stage for the portent.4But we should also consider the Homeric details which Ovid omits. First, he omits Homer's pathetic details of the birds and of their mother.(Iliad 2.314-17)Homer's... (shrink)

Although there are suggestions that the environmental attitudes of men and of women differ, there have been few studies that study and evaluate these differences at the workplace. Given the claim of Ecofeminist writers about the environmental superiority of women's environmental attitudes, and the proclaimed need of business to change attitudes and behaviour with regard to the environment, this is a surprise. The paper is based on 1022 (37% from women) questionnaires which were collected in a U.K. pharmaceutical company, and (...) it compares the empirical results with environmental attitude archetypes, such as those prescribed by O'Riordan. However, the attitude clusters that were found do not correspond greatly with such theoretical modes of environmental ethics. Instead, it appears that women were more likely to be actively involved in environmental behaviour, and showed greater scepticism towards the role of technology in the search for solutions to environmental problems. In addition, men sought to a much greater extent a consistency between an environmental rationality and their behaviour. Men's attitudes were also much more influenced by their position in the organisational hierarchy. There were few significant differences across age groups. (shrink)

I argue that we do not intentionally and rationally shape our character and values in major ways. I base this argument on the nature of transformative experiences, that is, those experiences which are transformative from personal and epistemological points of view. The argument is roughly this. First, someone who undergoes major changes in her character or values thereby undergoes a transformative experience. Second, if she undergoes such an experience, her reasons for changing in a major way are inaccessible to her (...) beforehand. Third, if such reasons are inaccessible beforehand, she cannot act on them and thus cannot rationally and intentionally shape her character or values. I also explore some consequences of my argument, especially those related to control and responsibility. (shrink)

During the first decades of the 20th century, many anthropologists who had previously adhered to a linear view of human evolution, from an ape via Pithecanthropus erectus and Neanderthal to modern humans, began to change their outlook. A shift towards a branching model of human evolution began to take hold. Among the scientific factors motivating this trend was the insight that mammalian evolution in general was best represented by a branching tree, rather than by a straight line, and that (...) several new fossil hominids were discovered that differed significantly in their morphology but seemed to date from about the same period. The ideological and practical implications of imperialism and WWI have also been identified as formative of the new evolutionary scenarios in which racial conflict played a crucial role. The paper will illustrate this general shift in anthropological theory for one particular scientist, William Sollas. Sollas achieved a synthesis of human morphological and cultural evolution in what I will refer to as an imperialist model. In this theoretical framework, migration, conflict, and replacement became the main mechanisms for progress spurred by 'nature's tyrant,' natural selection. (shrink)

In this paper, I show how idealizations contribute to social activities in science, such as the recruitment of experts to a research project. These contributions have not been explicitly discussed by recent philosophical accounts of scientific idealization. These accounts have focused on how idealizations influence activities like scientific theorization, explanation, and modeling. Other accounts focus on how idealizations influence policy-making and science communication. I expand these accounts by exploring the uses of idealized phylogenetic trees in science. Trees are not only (...) useful for improving our understanding and public communication of evolutionary history, but they also help with the organization of laboratories and collaboration among scientists. Attending to the relation between idealizations and these social practices in science matters. It can help us understand why idealized models become entrenched and why certain social practices change over time. (shrink)

Frequent lateral genetic transfer undermines the existence of a unique “tree of life” that relates all organisms. Vertical inheritance is nonetheless of vital interest in the study of microbial evolution, and knowing the “tree of cells” can yield insights into ecological continuity, the rates of change of different cellular characters, and the evolutionary plasticity of genomes. Notwithstanding within-species recombination, the relationships most frequently recovered from genomic data at shallow to moderate taxonomic depths are likely to reflect cellular inheritance. (...) At the same time, it is clear that several types of ‘average signals’ from whole genomes can be highly misleading, and the existence of a central tendency must not be taken as prima facie evidence of vertical descent. Phylogenetic networks offer an attractive solution, since they can be formulated in ways that mitigate the misleading aspects of hybrid evolutionary signals in genomes. But the connections in a network typically show genetic relatedness without distinguishing between vertical and lateral inheritance of genetic material. The solution may lie in a compromise between strict tree-thinking and network paradigms: build a phylogenetic network, but identify the set of connections in the network that are potentially due to vertical descent. Even if a single tree cannot be unambiguously identified, choosing a subnetwork of putative vertical connections can still lead to drastic reductions in the set of candidate vertical hypotheses.

We tried to determine whether this may be explained by a reduction of the ventilated areas in the lung, consecutive to closure of some airways. We have then tried to simulate these experimental results by studying the effects of various airways occlusions imposed on two concurrent models (symmetrical and dissymmetrical) of (...) the tracheo-bronchial tree. For each model, we successively evaluated the resistance of the normal lung, simulated a partial peripheral airways occlusion and estimated the induced changes in total resistance. Analytical expressions of the "occluded lung" elastance and resistance have been found for the symmetrical model but not for the dissymmetrical model (a graphical approach is proposed). With the symmetrical model, simulated results are comparable to experimental ones when the occlusion level is proximal. Whatever the dissymmetry level (δ) of the fractal tree model, we could not simulate the expected increase in resistance with the observed increase in elastance. We conclude that either the occlusion is non homogeneous or the lung impairment is not only a reduction in ventilated areas. (shrink)

Francesco Redi’s seventeenth-century experiments on insect generation are regarded as a key contribution to the downfall of belief in spontaneous generation. Scholars praise Redi for his experiments demonstrating that meat does not generate insects, but condemn him for his claim elsewhere that trees can generate wasps and gallflies. He has been charged with rejecting spontaneous generation only to change his mind and accept it, and in the process, with failing as a rigorous experimental philosopher. In this paper I defend Redi (...) from both of these charges. In doing so, I draw some broader lessons for our understanding of spontaneous generation. ‘Spontaneous generation’ does not refer to a single theory, but rather a landscape of possible views. I analyze Redi’s theoretical commitments and situate them within this landscape, and argue that his error in the case of insects from plants is not as problematic as previous commentators have said it is. In his research on gall insects Redi was addressing a different question from that of his experiments on insect generation—the question was not “Can insects come from nonliving matter?,” but rather, “Can insects come from living organisms which are not their parents?” In the latter case, he gave an answer which we now know to be false, but this was not due to any failure in his rigor as an experimental philosopher.

Approaching language change within a Darwinian framework constitutes a long-standing tradition within the literature of diachronic linguistics. However, many publications remain vague, omitting conceptual details or missing necessary terminology. For example, phylogenetic trees of language families are regularly compared to biological speciation, but definitions on mechanisms of inheritance, i.e. how linguistic information is transferred between individuals and cohorts, or on the linguistic correlates to genotype and phenotype are often missing or lacking. In light of this, Haider’s attempts to develop this (...) approach into a theoretically more precise position, closely mirroring principles of Darwinian natural selection in the dimension of diachronic grammatical change, but contrasting this with non-Darwinian lexical change. He draws a comparison to viral replication, essentially positing that grammar variants act as mental viruses, competing for replication in new hosts, i.e. children during critical periods of language acquisition. Haider proposes that in light of this competition for replication, the unconscious fixation of an individual’s grammar leads to diachronic grammatical change largely mirroring Darwinian natural selection. Despite the intuitive appeal this mode of reasoning may feature, the following response paper identifies and discusses a suit of shortcomings to this conceptualization. Some problems arise from underspecified theoretical notions, others due to the incomplete or inaccurate adoption of biological principles, and yet more through a partial incompatibility with empirical data. These criticisms do not amount to a dismissal of the Darwinian framework Haider is following, but to a rejection of Haider’s current position. Albeit it remains unclear if a truly Darwinian approach to language change can be reached, suggestions on how Haider’s theoretical notions could be further developed are made and pertinent efforts may ultimately lead to a productive theory.

I wholeheartedly endorse Grodzinsky's program of attempting to tie the particular deficits observed in Broca's aphasics' comprehension and production to changes in their mentally represented model of grammar. At the level of detail, however, I see problems with two specific changes that Grodzinsky posits. One is a default Agent-assignment strategy in comprehension. The other is the hypothesis that production involves pruning all functional projections above Agreement Phrase.

We propose in this article an indexing and retrieval approach applied on outline shapes. Models of objects are stored in a database using the textual descriptors of their silhouettes. We extract from the textual description a set of efficient similarity measures to index the silhouettes. The extracted features are the geometric quasi-invariants that vary slightly with the small change in the viewpoint. We use a textual description and quasi-invariant features to minimize the storage space and to achieve an efficient indexing (...) process. We also use the quad-tree structure to improve processing time during indexing. Using both geometric features and quad-tree decomposition facilitates recognition and retrieval processes. Our approach is applied on the outline shapes of three-dimensional objects. Experiments conducted on two well-known databases show the efficiency of our method in real-world applications, especially for image indexing and retrieval. (shrink)

There is a continuing debate in the field of perceptual organization as to whether the locus of global processing is early or late perceptual, as previous studies have yielded contrary results. The conducted behavioural study explored this issue with the paradigm of collating global processing with other process of perceptual organization, namely illusory contours processing. Interaction between these two processes of perceptual organization would indicate that global processing has an early perceptual locus, whereas the lack of such interaction would suggest (...) the late perceptual locus of global processing. In experiment 1, the effect of global dominance was obtained with the use of a compound figure composed of geometrical shapes with real edges. Results showed that the processing of the figure at the global level was faster and that it disrupted the processing of the figures from the local level. In experiment 1b, the compound figure was composed of local geometrical shapes generated with the use of the line-end induced illusory contours. Local elements with illusory contours did not affect the processing of the hierarchical structure and the effect of global precedence occurred without any changes. In experiment 2a, a global advantaged effect within a compound figure with local elements with real edges was obtained in the paradigm of attention divided between levels of the hierarchical structure. When illusory contours of local elements of a compound figure were introduced to this paradigm, this again had no effect on the perceptual global advantage. The results demonstrate the lack of interaction between global processing and illusory contour processing, indicating that the locus of global processing is rather late perceptual. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:A Changed Life: Becoming True to Who I amJay Kyle PetersenI was born intersex in 1952 in the county hospital of a very small, ultraconservative town in rural Southwestern Minnesota. My biological parents and paternal grandparents raised me on a small family farm nearby. I knew by age four I was a boy. No one told me. There was nothing to decide. I have always known I am male. (...) My parents never discussed my unusual condition with me and died having never accepted me. They denied my true identity and instead chose to give me a girl’s name and raise me as a girl.My paternal grandmother knew I was different. She lived on the farm with us and, as she explained to me later on in life, changed my diapers and helped take care of me as an infant and toddler. She also was a Certified Nurse’s Aide in the pediatric ward of the county hospital where I was born and could see that anatomically I was different from other infants. She remained my lifelong ally and friend until her death in 1993. She and Grandpa provided an oasis in their farmhouse where I felt accepted. I felt relaxed and comfortable in their company, and could just be myself. Grandpa took me fishing. Grandma drove me to 4–H State Fair demonstrations and supported me in the audience for which she had helped prepare me. My grandmother taught me good humor, excellence and how it was okay to make mistakes. Much later, in 1977, she drove four hours alone to Minneapolis in blizzard conditions to be my “concerned family person” during chemical dependency treatment, when my mother and dad refused and she also celebrated with me after my successful completion of the program. I loved her and she loved me and she showed it. With her I found refuge away from the pressure and abuse in our farmhouse.But my grandparents and parents did not show me affection physically. The only touch I felt from my family, except my paternal grandparents, was abusive including certain religious figures outside our family. Farm animals and pets provided warmth, love, acceptance, and companionship. I loved riding around the farm on the back of my pet pig, Lucy. Nature, especially trees, wild weather, and local lakes provided rest for my stretched, weary nerves and stimulation for my imagination. There was something about the vivid and contrasting colors, even the sounds and livingness about it all—rich deep moist greens, clean pure vast open blues, dark warm earth which I laid upon and felt in my hands. These and the soothing sounds of the wind gently moving through tree leaves and corn leaves and the lake water lapping calmly upon sandy shores, as Grandpa cast out his line: all this I found both relaxing and energizing and allowed for me the safety and environment to rest, let go and expand so my natural inclinations to express myself creatively could open up. Otherwise, I had a very lonely, frustrated, painful, humiliating childhood and adolescence filled with mounting anger and a sense of futility because I could not be or express my real male self—including my attraction to girls.The cultural and religious pressure I felt, the increased abuse and social lies I was forced to live with—including being forced to wear girls’ clothing against my will—became unbearable. I sought [End Page 106] refuge in addiction early on—food for comfort, nicotine for mood alteration, alcohol given to me by my dad, and more. I became suicidal, and remained for a long time terribly depressed.The geneticist I have consulted for the last four years says that physicians who examined me prior to my genital surgeries described my genitals as “male structures formed without enough testosterone,” rather than female structures formed in the presence of excess androgen. She told me that the features recorded in my medical records, and that she had observed, indicate androgen exposure in utero along with an inherited genetic condition such that she says my condition began at conception. I was born with XX karyotype and testing for usual causes for androgen excess with someone... (shrink)

Thomas Kuhn had little to say about scientific change in biological science, and biologists are ambivalent about how applicable his framework is for their disciplines. We apply Kuhn’s account of paradigm change to evolutionary microbiology, where key Darwinian tenets are being challenged by two decades of findings from molecular phylogenetics. The chief culprit is lateral gene transfer, which undermines the role of vertical descent and the representation of evolutionary history as a tree of life. To assess Kuhn’s relevance to (...) this controversy, we add a social analysis of the scientists involved to the historical and philosophical debates. We conclude that while Kuhn’s account may capture aspects of the pattern of an episode of scientific change, he has little to say about how the process of generating new understandings is occurring in evolutionary microbiology. Once Kuhn’s application is limited to that of an initial investigative probe into how scientific problem-solving occurs, his disciplinary scope becomes broader. (shrink)

At this time when the development of synthetic biology and artificial intelligence are changing the world around us, philosophers and scientists, first of all, must converge to analyze the present and predict the ethical-social consequences and biological dangers associated with new “living entities” that are not the result of the natural evolutionary process. As synthetic/artificial life forms (xenobots, robots, transgenic organisms, etc.) become more and more abundant and sophisticated, it seems first of all necessary to bring some order to all (...) this new biodiversity, establishing what is alive and what is not, and analyzing the consequences of this incessant creative activity. Here I intend to organize all these human-made entities and clarify their status as living beings or artificial elements, leaving the door open to an uncertain future in which we will be able to see how “the artificial” and “the natural” could merge to originate something different from everything known. Accordingly, I propose the creation of a new domain, Lithbea, which includes all synthetic and artificial entities within a new kingdom called Humade (derived from human-made). I have also included viruses in a new realm, the Viral kingdom, because they were excluded from the classical three-domain tree of life despite playing a fundamental role in the evolution of biodiversity on Earth. Finally, I make a brief comment on the unpredictability of the unknown, the implications of this new landscape of biodiversity, and the uncertain future of all these advances. (shrink)

This paper combines domestic and international research results to analyze and study the difference between the attribute features of English phrase speech and noise to enhance the short-time energy, which is used to improve the threshold judgment sensitivity; noise addition to the discrepancy data set is used to enhance the recognition robustness. The backpropagation algorithm is improved to constrain the range of weight variation, avoid oscillation phenomenon, and shorten the training time. In the real English phrase sound recognition system, there (...) are problems such as massive training data and low training efficiency caused by the super large-scale model parameters of the convolutional neural network. To address these problems, the NWBP algorithm is based on the oscillation phenomenon that tends to occur when searching for the minimum error value in the late training period of the network parameters, using the K-MEANS algorithm to obtain the seed nodes that approach the minimal error value, and using the boundary value rule to reduce the range of weight change to reduce the oscillation phenomenon so that the network error converges as soon as possible and improve the training efficiency. Through simulation experiments, the NWBP algorithm improves the degree of fitting and convergence speed in the training of complex convolutional neural networks compared with other algorithms, reduces the redundant computation, and shortens the training time to a certain extent, and the algorithm has the advantage of accelerating the convergence of the network compared with simple networks. The word tree constraint and its efficient storage structure are introduced, which improves the storage efficiency of the word tree constraint and the retrieval efficiency in the English phrase recognition search.

This paper provides an overview of how the social licence to operate (SLO) of the Swedish forest industry has been developed over time. For many decades, the SLO has been implicitly operating, shaped by dominant discourses of the day. We can see these SLOs through the agrarian, industrial and post-industrial era. During this era, a focus on bioenergy has seen whole stump removal become a more mainstream practice. This practice gained increasingly widespread acceptance when framed as a necessary response to (...) climate change. However, research has identified problems associated with whole stump removal, including decreased biodiversity, nutrient removal, soil acidification and mechanical soil preparation threatening soil carbon stores. In light of these recent developments, this paper examines the role of knowledge production and accepted discourses in the creation and maintenance of an industry’s SLO. By providing an overview of key legislative changes in the history of forest management alongside data from .. (shrink)

Observational and experimental discoveries of new factual entities such as objects, systems, or processes, are major contributors to some advances in the life sciences. Yet, whereas discovery of theories was extensively deliberated by philosophers of science, very little philosophical attention was paid to the discovery of factual entities. This paper examines historical and philosophical aspects of the experimental discovery by Carl Woese of archaea, prokaryotes that comprise one of the three principal domains of the phylogenetic tree. Borrowing Kuhn’s terminology, (...) this discovery of a major biological entity was made during a ‘normal science’ project of building molecular taxonomy for prokaryotes. Unexpectedly, however, an observed anomaly instigated the discovery of archaea. Substantiation of the existence of the new archaeal entity and consequent reconstruction of the phylogenetic tree prompted replacement of a long-held model of a prokarya and eukarya bipartite tree of life by a new model of a tripartite tree comprising of bacteria, archaea, and eukarya. This paper explores the history and philosophical implications of the progression of Woese’s project from normal science to anomaly-instigated model-changing discovery. It is also shown that the consequential discoveries of RNA splicing and of ribozymes were similarly prompted by unexpected irregularities during normal science activities. It is thus submitted that some discoveries of factual biological entities are triggered by unforeseen observational or experimental anomalies. (shrink)

This article engages through an interdisciplinary approach to re-envision Tangintebu Theological College’s (TTC) model of theological education in the context of climate change in Kiribati. It utilises the anthropological theory of symbolic interactionism within missiological, cultural and, theological studies of climate change. It argues for the coconut tree as an appropriate cultural conceptual metaphorical idiom for translating and understanding Christian faith and shaping a theological pedagogy within the Kiribati context of climate change. The coconut image is an indigenous, holistic (...) way of knowing and learning informed by Kiribati cosmology embedded within people’s experiences and understanding of the coconut tree. Its life-centeredness has the potential to contextualise the theological curriculum and teaching methodology to assist in equipping theological students with climate change-sensitive approaches. The qualitative method was utilised to allow participants to reflect on their experiences of climate change in relation to the mission of the church. The data that informs this article was generated through unstructured interviews and focus group discussions with members of the Kiribati Uniting Church (KUC). The data was analysed using symbolic interactionism. The results suggest that the Kiribati people symbolically interact with God through their understanding of the coconut tree, which is conceived as the embodiment of God’s presence. It became clear that while this world view informs the faith of members of the KUC, the TTC curriculum has sidelined it, resulting in miseducation of pastors because this omission means they are not equipped to engage with the challenge of climate change. The participants argued that there is an urgent need to understand theological education and ministerial formation within the indigenous framework of Kiribati coconut imagination that is embedded in the promotion of justice and equitable society not only for human beings but for all of God’s creation through symbolic interaction with the presence of God in the coconut.

Debates surrounding the high-level contents of perceptual experience focus on whether weperceive the high-level properties of visual objects, such as the property of being a pine tree. Thispaper considers instead whether we perceive the high-level properties of visual scenes, such asthe property of being a forest. Liberals about the contents of perceptual experience have offered avariety of phenomenal contrast cases designed to reveal how the high-level properties of objectsfigure in our visual experience. I offer a series of equivalent phenomenal (...) contrast cases intendedto show how the high-level properties of visual scenes also figure in visual experience. Thisfirst-person evidence of high-level scene perception is combined with third-person evidence fromthe extensive empirical literature on scene categorisation. Critics of liberalism have attempted todeflate existing phenomenal contrast cases by explaining the contrasts in terms of non-perceptualcontents or in terms of attentional changes. I show that neither response is applicable to mycontrast cases and conclude that we do indeed perceptually experience the high-level propertiesof visual scenes. (shrink)

Considering the properties of mirror neurons (MNs) in terms of development and phylogeny, we offer a novel, unifying, and testable account of their evolution according to the available data and try to unify apparently discordant research, including the plasticity of MNs during development, their adaptive value and their phylogenetic relationships and continuity. We hypothesize that the MN system reflects a set of interrelated traits, each with an independent natural history due to unique selective pressures, and propose that there are at (...) least three evolutionarily significant trends that gave raise to three subtypes: hand visuomotor, mouth visuomotor, and audio–vocal. Specifically, we put forward a mosaic evolution hypothesis, which posits that different types of MNs may have evolved at different rates within and among species. This evolutionary hypothesis represents an alternative to both adaptationist and associative models. Finally, the review offers a strong heuristic potential in predicting the circumstances under which specific variations and properties of MNs are expected. Such predictive value is critical to test new hypotheses about MN activity and its plastic changes, depending on the species, the neuroanatomical substrates, and the ecological niche. (shrink)

In the paper A non-implication between fragments of Martin’s Axiom related to a property which comes from Aronszajn trees , Proposition 2.7 is not true. To avoid this error and correct Proposition 2.7, the definition of the property is changed. In Yorioka [1], all proofs of lemmas and theorems but Lemma 6.9 are valid about this definition without changing the proofs. We give a new statement and a new proof of Lemma 6.9.
