Two new modes of thinking have spread through systematics in the twentieth century. Both have deep historical roots, but they have been widely accepted only during this century. Population thinking overtook the field in the early part of the century, culminating in the full development of population systematics in the 1930s and 1940s, and the subsequent growth of the entire field of population biology. Population thinking rejects the idea that each species has a natural type (as the earlier essentialist view (...) had assumed), and instead sees every species as a varying population of interbreeding individuals. Tree thinking has spread through the field since the 1960s with the development of phylogenetic systematics. Tree thinking recognizes that species are not independent replicates within a class (as earlier group thinkers had tended to see them), but are instead interconnected parts of an evolutionary tree. It lays emphasis on the explanation of evolutionary events in the context of a tree, rather than on the states exhibited by collections of species, and it sees evolutionary history as a story of divergence rather than a story of development. Just as population thinking gave rise to the new field of population biology, so tree thinking is giving rise to the new field of phylogenetic biology. (shrink)

In most contexts, emotional support is crucial for the well-being of low-income single women and their children. Support from women may be especially important for single mothers because of precarious ties to their children’s fathers, the prevalence of extended matrifocal living arrangements, and gendered norms that place men as providers of financial rather than emotional support. However, in contexts marked by economic insecurity, spatial dispersion of families, and changing gender norms and kinship obligations, such an expectation may be problematic. Applying (...) theories of emotional capital and family bargaining processes, we address three questions: What is the gender composition of emotional support that single mothers receive? How does gender composition change over time? Does the gender composition of emotional support affect the self-reported stress of single mothers? Drawing on data from a unique data set on 462 low-income single mothers and their kin from Nairobi, Kenya, we uncover three key findings. One, whereas the bulk of strong emotional support comes from female kin, about 20 percent of respondents report having male-dominant support networks. Two, nearly 30 percent of respondents report change favoring men in the composition of their emotional support over six months. Three, having a male-dominant emotional support network is associated with lower stress. These results challenge what is commonly taken for granted about gender norms and kinship obligations in non-Western contexts. (shrink)

The same attitudes that allowed a significant increase in the anthropogenic greenhouse gas (GHG) concentrations that are causing climate change are the same attitudes that are retarding an adequate ethical response to the impact that climate change is having on both human populations and the rest of the planet. The industrialized nations of the West paid little attention during the past three centuries to the impacts that their economies and cultures were having on the environment, both locally and globally. There (...) was an underlying belief that the planet could indefinitely absorb the wastes of manufacturing, and the natural resources that were fuelling industrialization were seemingly endless if not actually ..

Discussions of the theory and practice of systematics and evolutionary biology have heretofore revolved around the views of philosophers of science. I reexamine these issues from the different perspective of the philosophy of history. Just as philosophers of history distinguish between chronicle (non-interpretive or non-explanatory writing) and narrative history (interpretive or explanatory writing), I distinguish between evolutionary chronicle (cladograms, broadly construed) and narrative evolutionary history. Systematics is the discipline which estimates the evolutionary chronicle. ¶ Explanations of the events described in (...) the evolutionary chronicle are not of the covering-law type described by philosophers of science, but rather of the how-possibly, continuous series, and integrating types described by philosophers of history. Pre-evolutionary explanations of states (in contrast to chroniclar events) are still widespread in "evolutionary" biology, however, because evolutionary chronicles are in general poorly known. To the extent that chronicles are known, the narrative evolutionary histories based on them are structured like conventional historical narratives, in that they treat their central subjects as ontological individuals. This conventional treatment is incorrect. The central subjects of evolutionary narratives are clades, branched entities which have some of the properties of individuals and some of the properties of classes. Our unconscious treatment of the subjects of evolutionary narratives as individuals has been the cause of erroneous notions of progress in evolution, and of views that taxa "develop" ontogenetically in ways analogous to individual organisms. We must rewrite our narrative evolutionary histories so that they properly represent the branching nature of evolution, and we must reframe our evolutionary philosophies so that they properly reflect the historical nature of our subject.

Institutions of higher education in the United States are remarkably diverse in their educational purposes, their organizational structure, and their architectural styles. But underlying all this diversity are two distinct historical models: the decentralized British "collegiate" model of university education, and the centralized Germanic university model. Early American higher education grew out of the British collegiate tradition and emphasized the comprehensive development of students' intellect and character, while the Germanic university tradition, introduced in the late 1800s, shifted the focus to (...) technical scholarship and research. The Germanic university model held sway for much of the twentieth century, but there is now a widespread renewal of interest in the older decentralized British collegiate model, and in universities across the United States and around the world, small "residential colleges" like those at Oxford and Cambridge are now being planned and built. These residential colleges or "houses" (as they are sometimes called) provide small, stable, faculty-led, home-like environments for a few hundred students each, and their social and architectural design seeks to counteract the impersonal bureaucratic experience that students often have in large Germanic-style universities. This revival of the collegiate model of university organization is one of the most important trends in the design of educational communities in the world today. (shrink)

Specialist Sport Programs are an underexamined activity that combines the best features of two different contexts for adolescent development: a sporting program and a secondary school. A mixed-methods study was conducted to determine the influence of participation in SSPs on the educational outcomes of lower secondary students in Western Australia. The results demonstrated a significant improvement in specialist students' mean grade for Mathematics over the course of a year, while their mean grade for all other subjects, and their level of (...) engagement with school, remained stable over the same period of time. Semi-structured interviews were also conducted with key stakeholders. Overall, the participants felt that SSPs had a positive influence on students' engagement with school, and that this engagement had a positive impact on their academic achievement. Taken together, the results of this research suggest that there is a role for SSPs in promoting positive educational outcomes for lower secondary students attending public schools located in low SES areas.

In CQ 34 , 167–74, Janet Fairweather makes the interesting suggestion that the elegiacs by Gallus on the Qasr Ibrim papyrus should be understood as ‘a fragment of an amoebaean song-contest’. This hypothesis, as she notes, might explain why the papyrus' quatrains are set apart by spaces and by an odd type of symbol, and treat ‘separate, indeed discrepant, topics’, yet show ‘unmistakable verbal and thematic connections’. Fairweather's discussion is thorough, but overlooks one small piece of evidence for Gallan amoebaean (...) verse. (shrink)

"The Natural System" is the abstract notion of the order in living diversity. The richness and complexity of this notion is revealed by the diversity of representations of the Natural System drawn by ornithologists in the Nineteenth Century. These representations varied in overall form from stars, to circles, to maps, to evolutionary trees and cross-sections through trees. They differed in their depiction of affinity, analogy, continuity, directionality, symmetry, reticulation and branching, evolution, and morphological convergence and divergence. Some representations were two-dimensional, (...) and some were three-dimensional; n-dimensional representations were discussed but never illustrated. The study of diagrammatic representations of the Natural System is made difficult by the frequent failure of authors to discuss them in their texts, and by the consequent problem of distinguishing features which carried meaning from arbitrary features and printing conventions which did not. Many of the systematics controversies of the last thirty years have their roots in the conceptual problems which surrounded the Natural System in the late 1800s, problems which were left unresolved when interest in higher-level systematics declined at the turn of this century.

Neither our evolutionary past, nor our pre-literate culture, has prepared humanity for the use of technology to provide records of the past, records which in many context become normative for memory. The demand that memory be true, rather than useful or pleasurable, has changed our social and psychological under-standing of ourselves and our fellows. The current vogue for lifelogging, and the rapid proliferation of digital memory-supporting technologies, may accelerate this change, and create dilemmas for policymakers, designers and social thinkers.

In the last thirty years systematics has transformed itself from a discipline concerned with classification into a discipline concerned with reconstructing the evolutionary history of life. This transformation has been driven by cladistic analysis, a set of techniques for reconstructing evolutionary trees. Long interested in the large-scale structure of evolutionary history, cladistically oriented systematists have recently begun to apply "tree thinking" to problems near the species level. ¶ In any local ("non-dimensional") situation species are usually well-defined, but across space and (...) time the grouping of populations into species is often problematic. Three views of species are in common use today, the biological species concept, the evolutionary species concept, and the phylogenetic species concept. Each of these has strengths and weaknesses, but no matter which is applied, exact counts of the number of species in any extended area will always be ambiguous no matter how much factual information is available. This ambiguity arises because evolution is an historical process, and the grouping of organisms into species always depends to some extent upon expectations of the future behavior of those organisms and their descendants, expectations that cannot be evaluated in the present. The existence and special character of the species problem is itself one of the central pieces of evidence for evolution. (shrink)

In the eighteenth century the category of the aesthetic sought to bridge the gap between the prevalent dualities of Cartesian thought: art and science, history and science, prejudice and truth. This special issue of _boundary 2_ addresses current debates about the status of art in the context of global modernity. The range of arguments represented here cover a broad historical scope—from Cartesianism to present-day global modernity—of cultural discourse on the aesthetic to bring a focus to contemporary discussions of the corollary (...) concepts of beauty, virtue, taste, and truth. These essays present a rich and provocative account of the place of the aesthetic in late-twentieth-century culture. Included in this volume are considerations of the relation between theories of art and the avant-garde; art’s relation to cognition; the aesthetic as history; the aesthetic as a unique access to modernity; and its impact on problems of identity formation, ideology, and resistances to the institutional powers inherent in dominant social formations. _Contributors. _Charles Altieri, Peter Burger, David Carroll, Anthony J.

This brief notice records anecdotes about Wittgenstein gathered from Br. Herbert Kaden OSB.

Accounts of the evolutionary past have as much in common with works of narrative history as they do with works of science. Awareness of the narrative character of evolutionary writing leads to the discovery of a host of fascinating and hitherto unrecognized problems in the representation of evolutionary history, problems associated with the writing of narrative. These problems include selective attention, narrative perspective, foregrounding and backgrounding, differential resolution, and the establishment of a canon of important events. The narrative aspects of (...) evolutionary writing, however, which promote linearity and cohesiveness in conventional stories, conflict with the underlying chronicle of evolution, which is not linear, but branched, and which does not cohere, but diverges. The impulse to narrate is so great, however, and is so strongly reinforced by traditional schemes of taxonomic attention, that natural historians have more often abandoned the diverging tree than they have abandoned the narrative mode of representation. If we are to understand the true nature of the evolutionary past then we must adopt “tree thinking”, and develop new and creative ways, both narrative and non-narrative, of telling the history of life.

The species problem is one of the oldest controversies in natural history. Its persistence suggests that it is something more than a problem of fact or definition. Considerable light is shed on the species problem when it is viewed as a problem in the representation of the natural system (sensu Griffiths, 1974, Acta Biotheor. 23: 85–131; de Queiroz, 1998, Philos. Sci. 55: 238–259). Just as maps are representations of the earth, and are subject to what is called cartographic generalization, so (...) diagrams of the natural system (evolutionary trees) are representations of the evolutionary chronicle, and are subject to a temporal version of cartographic generalization which may be termed systematic generalization. Cartographic generalization is based on judgements of geographical importance, and systematic generalization is based on judgements of historical importance, judgements expressed in narrative sentences (sensu Danto, 1985, Narration and knowledge, Columbia Univ. Press, New York). At higher systematic levels these narrative sentences are conventional and retrospective, but near the "species" level they become prospective, that is, dependent upon expectations of the future. The truth of prospective narrative sentences is logically indeterminable in the present, and since all the common species concepts depend upon prospective narration, it is impossible for any of them to be applied with precision.

Velina Hasu Houston’s theatrical representations focus on exploring cultural collision and coalescence in transnational communities. With her biographical and cultural background deeply influenced by her Japanese mother’s way of life and sense of values, Houston has been open-minded in creating a new viewpoint through which to look at Japan, the United States and the world. Calligraphy is quite challenging in that it looks at her mother’s aging from both Japanese and American perspectives. It sheds new light on not only understanding (...) the beauty in the aging process but also women’s memories that have value beyond the personal. Since she wrote Tea based on her mother’s life as a war bride, Houston has presented a pioneering, in-depth exploration of Asian women’s memories that have been historically ignored in the United States. This paper examines how Houston’s insight into transnationalism through the transformative nature of cultural identity and change inspires her to re-envision women’s writing and highlights the need for a re-examination of the power of love and beauty.

The Low-and-Lower-Middle-Income Trap (LLMIT) poses a significant challenge for economies in low-and-lower-middle-income countries (LLMICs), hindering their progress towards higher income levels. This issue is especially prevalent in Southeast Asia, South Asia, and Sub-Saharan Africa, where job opportunities are scarce, and incomes are unstable. To address these challenges and promote economic development, particularly in terms of innovation and poverty reduction, it is essential to accelerate business activities, with a focus on fostering startup ecosystems. Despite the importance of this relationship, there is (...) a noticeable gap in research, especially regarding the connection between startup ecosystems and economic development aimed at poverty reduction in LLMICs striving to overcome the LLMIT. This study conducts a qualitative empirical review to identify crucial conditions for promoting startup ecosystems as contributors to economic development. Preliminary demonstrations of theoretical foundations for escaping LLMIT through nurturing startup ecosystems are presented, referencing 15 selected literatures. Using the Grounded Theory Approach with ATLAS.ti, the findings highlight the scarcity of research on the mechanisms linking startup ecosystems to economic progress, notably in the context of poverty reduction in LLMICs facing LLMIT. The study emphasizes the necessity for continuous support in reviewing economic development policies and regularly monitoring economic performance, particularly in the aim of extensively mitigating LLMIT.

LTP is thought to be an experimental model for studying the cellular mechanism of learning and memory. Shors & Matzel review some contradictory data concerning the linkage between LTP and memory and suggest that LTP does not underlie learning and memory. LTP is a cellular and synaptic process and cannot be a memory mechanism. In fact, it is a cellular information storage mechanism.

Leibniz's correspondence from his years spent in Paris (1672-1676) reflects his growth to mathematical maturity whereas that from the years 1676-1701 reveals his growth to maturity in science, technology and medicine in the course of which more than 2000 letters were exchanged with more than 200 correspondents. The remaining years until his death in 1716 witnessed above all the appearance of his major philosophical works. The focus of the present work is Leibniz's middle period and the core themes and core (...) texts from his multilingual correspondence are presented in English from the following subject areas: mathematics, natural philosophy, physics (and cosmology), power technology (including mining and transport), engineering and engineering science, projects (scientific, technological and economic projects), alchemy and chemistry, geology, biology and medicine.

The Logic of Human Personality shows how the ancient definition of person remains useful today, and explains how it happened to fall into disuse. The method of using the categories of Aristotle is illustrated by showing how action, relation, and time as well as the fundamental category of substance, can help us understand what it is to be a person. The Logic of Human Personality agrues, against Mill and others who have found Aristotle's categories unsatisfactory, that in fact they are (...) useful for much psychological and anthropological research today, particularly in the intercultural field.

138 titles across a wide range of scholarly publications illustrate the conceptual affinities that connect the palaetiological sciences of biological systematics, historical linguistics, and stemmatics. These three fields all have as their central objective the reconstruction of evolutionary "trees of history" that depict phylogenetic patterns of descent with modification among species, languages, and manuscripts. All three fields flourished in the nineteenth century, underwent parallel periods of quiescence in the early twentieth century, and in recent decades have seen widespread parallel revivals. (...) "Tree thinking" (O'Hara, 1988) is now standard within evolutionary biology, and the unity of what William Whewell called palaetiology is being once again appreciated by scholars and scientists in many fields.

Classifications of animals and plants have long been represented by hierarchical lists of taxa, but occasional authors have drawn diagrammatic versions of their classifications in an attempt to better depict the "natural relationships" of their organisms. Ornithologists in 19th-century Britain produced and pioneered many types of classificatory diagrams, and these fall into three groups: (a) the quinarian systems of Vigors and Swainson (1820s and 1830s); (b) the "maps" of Strickland and Wallace (1840s and 1850s); and (c) the evolutionary diagrams of (...) the post-Darwin authors (1860 on). The quinarians distinguished between affinity and analogy and used both in their classifications, whereas Strickland rejected the quinarians' belief in numerical regularity and their use of analogy. Wallace's "maps" are easily given an evolutionary interpretation, and his approach was taken up and modified by later evolutionary anatomists. Sharpe returned to Strickland's methods and merely appended a superficial evolutionary interpretation. Contrary to common belief systematics has a rich conceptual history, and many of the conceptual developments in 19th-century systematics were made by ornithologists. (shrink)
