This paper aims to establish the connection between the theoretical and practical aims of the Office of the Hydrographer of the British Admiralty and Charles Darwin’s (1809–1882) work on coral reefs from 1835 to 1842. I also emphasize the consistent zoological as well as geological reasoning contained in these texts. The Office’s influences have been previously overlooked, despite the Admiralty’s interest in using coral reefs as natural instruments. I elaborate on this by introducing the work of (...) Alexander Dalrymple (1737–1808), the first hydrographer of the Admiralty and a figure who has flown under the radar of the history of coral reef theories. I show that Dalrymple introduced a unified account of coral reefs in which multiple features of the coral reefs, such as their shape, slope of the sides, ridges, channels, and elevation relative to the water, were all explained by the action of the winds and waves—and proposed that one could use these features to predict seafaring conditions around the islands. Then, I show that Darwin’s “Coral Islands” (1835) and his _Coral Reefs_ monograph (1842) spoke to these hydrographical issues and did so, at times, by way of zoological reasoning. It was, for instance, the coral behavior and the related notion of a zoological or botanical _station_ that ultimately proved the biggest blow to the Admiralty’s aim to use the coral reefs as instruments because it eroded many uniform predictions regarding the past or future of a coral reef. Connecting these themes leads us to a surprising conclusion: that Darwin’s theory of coral reefs, long a model instance of Darwin making uniform predictable inferences, was, in actuality, also his first formal encounter with something at times the entire opposite.

Coral bleaching has impacted reefs worldwide and the predictions of near‐annual bleaching from over two decades ago have now been realized. While technology currently provides the means to predict large‐scale bleaching, predicting reef‐scale and within‐reef patterns in real‐time for all reef users is limited. In 2020, heat stress across the Great Barrier Reef underpinned the region's third bleaching event in 5 years. Here we review the heterogeneous emergence of bleaching across Heron Island reef habitats and discuss the oceanographic (...) drivers that underpinned variable bleaching emergence. We do so as a case study to highlight how reef end‐user groups who engage with coral reefs in different ways require targeted guidance for how, and when, to alter their use of coral reefs in response to bleaching events. Our case study of coral bleaching emergence demonstrates how within‐reef scale nowcasting of coral bleaching could aid the development of accessible and equitable bleaching response strategies on coral reefs.

If we are to ensure the persistence of species in an increasingly warm world, of interest is the identification of drivers that affect the ability of an organism to resist thermal stress. Underpinning any organism's capacity for resistance is a complex interplay between biological and physical factors occurring over multiple scales. Tropical coral reefs are a unique system, in that their function is dependent upon the maintenance of a coral–algal symbiosis that is directly disrupted by increases in (...) water temperature. A number of physical factors have been identified as affecting the biological responses of the coral organism under broadscale thermal anomalies. One such factor is water flow, which is capable of modulating both organismal metabolic functioning and thermal environments. Understanding the physiological and hydrodynamic drivers of organism response to thermal stress improves predictive capabilities and informs targeted management responses, thereby increasing the resilience of reefs into the future.

Diving into the life of the tropical coral reefs and Amadou Hampâté Ba’s reflections on the person conjoin in this work, which is at once philosophical and poetic. The permeable parameters of philosophy, which enable thought to hover between unstable contours rather than to prioritize secure foundations, open to a porous imagination, tracing and retracing panoramic geographies and contemporary tensions of globalization and development. Porous imagination slips, glides, between archipelagos of clay rooftops and refuge dotting the Sudan and (...) the smallest of creatures, source of half the earth’s oxygen and base of the global food chain, the plankton. Concomitantly, ideational codes of nation, continent, humanity, nature, land and water interactively stretch and unwind, shaping a polymetrics of sites and an aesthetics of nourishment. In an epoch beset by the treacherous fractals of overpowering domination and luminous liberation, the morphosis of philosophy through transdisciplinary and transcultural interpretation offers new ways of listening to and retuning songs of sorrow and lament.

Studies of how scientists select research problems suggest the process involves weighing a number of factors, including funding availability, likelihood of success versus failure, and perceived publishability of likely results, among others. In some fields, a strong personal interest in conducting science to bring about particular social and environmental outcomes plays an important role. Conservation biologists are frequently motivated by a desire that their research will contribute to improved conservation outcomes, which introduces a pair of challenging questions for managers of (...) science and scholars of policies governing science: 1) How do scientists integrate that goal into their processes of research priority evaluation, and 2) How can managers and funders of science utilize that knowledge in designing and administering funding programs? I use Q method to uncover four distinct schools of thought amongst researchers and knowledge-users about the merits of possible research priorities for coral reefs; one of the axes along which these schools of thought differ is in their interpretation of how science can and should interact with policy. The results reveal that perceived severity of reef stressors plays a role for some participants. Disciplinary training does not appear to be a major influence on research priority evaluation, but individual participants indicated professional expediency does prevent some researchers from pursuing or advocating that others pursue topics outside of that disciplinary specialty. Influences on and processes in research prioritization uncovered in this study have the potential to lead to counter-productive disciplinary path dependencies. From these results and building on outside literature, I conclude that better coordination and communication about research priorities across disciplines and with broader stakeholders – including knowledge users – could improve the research enterprise’s ability to contribute to meaningful societal and conservation goals. These findings are relevant to researchers and research administrators across disciplines that seek to conduct or fund science that is useful in addressing specific goals. (shrink)

Recent years have seen a proliferation of non-governmental organisations with a mission to help redress various social and environmental problems, but the effectiveness of these organisations in carrying out their stated goals is rarely assessed or critically examined. It has become increasingly clear, however, that these organisations vary greatly in their level of competence and professionalism. Many of them are ineffective, and in some cases they may even exacerbate the problems they set out to solve. These difficulties are based upon (...) flawed assumptions about how civil society can correct social ills, and about how institutions that are intermediate between the individual and the state can carry out effective change. To illustrate these points with an environmental example, we present the case of Jamaica's coral reefs, which have been under stress for decades. Both the causes of reef degradation and the solutions to these problems can be clearly outlined. Many well-intentioned organisations and individuals have been involved in the attempt to stem or reverse the damage, and significant funding has been channelled through these agencies. In spite of this, there has been no documented improvement in the condition of the reefs, apart from some natural regeneration that owed nothing whatever to any human activity. The problem is that the known solutions have not been implemented. This has happened for several reasons. First, government organisations have actively encouraged NGOs to undertake the responsibility of protecting sections of the coastline, but without any proper assessment of the capacity of those organisations to do so, and in some cases actively preventing them from acquiring that capacity. Second, the proliferation of NGOs has been counter-effective, resulting in duplication of effort, competition for limited funds, and conscious or unconscious misrepresentation of results. Third, the utilisation of NGOs to solve environmental problems often results in an increase in the number of levels of management, resulting in inefficient utilisation of funds. The known solutions to the degradation in the Jamaican marine environment principally involve reducing fishing pressures at a national level and the reduction of pollution by local municipalities. The effective role of NGOs in bringing about these two solutions therefore differs: where national changes are necessary, government centralisation and effective enforcement are necessary, although NGOs could still play a useful auxiliary or augmenting role. With local problems like municipal pollution, NGOs may be better able to lead in catalysing and implementing change, although the government could usefully provide coordination and support. These differences illustrate the fallacy in the simplistic assumption that rising public concern, increased levels of funding and a growing number of people and/or organisations involved in conservation will lead to environmental improvement. Effective hierarchical organisation is still a prerequisite for bringing about effective solutions, although the mode of organisation adopted should be a function of the particular solution necessary. Finally, since many NGOs have effectively functioned as parasitical organisations that have consumed public funding without any discernible public benefit, NGOs should be subject to the same scrutiny and assessment as any private sector organisation contracted to the government and/or donor agencies, and those who fail to perform should be barred from further receipt of public funds.

Aggregation methods allow one to replace a large scale dynamical system (micro-system) by a reduced dynamical system (macro-system) governing a small number of global variables. This aggregation of variables can be performed when two time scales exist, a fast time scale and a slow time scale. Perturbation theory allows to obtain an approximated aggregated dynamical system which describes the behaviour of a few number of slow time varying variables which are constants of motion of the fast part of the micro-system. (...) Aggregation methods are applied to the case of the devastation of the great barrier reef by the starfishes. We recall the Antonelli/Kazarinoff model which implies a stable limit cycle for the corals and starfish populations. This prey-predator model describes the interactions between two species of corals and the starfish. Then, we generalize the Antonelli/Kazarinoff model to the case of two spatial patches with a fast part describing the starfish migration on the patches and the human manipulation of the communities by divers and, a slow part describing the growth and the interactions between the populations. We obtain an aggregated model governing the total coral densities on the patches and the total starfish population. This model can exhibit stable limit cycle oscillations and a Hopf bifurcation. The critical value of the bifurcation parameter is expressed in terms of the proportions of coral species and starfish on the two patches. This implies for example that rather than random killing of starfish by the Australian military, it may be better to send teams of divers to outbreaking reefs when they first occur who will then manipulate the community structure to increase protection.

A lo largo de los siglos XVII y XVIII se desarrollaron sucesivas reformulaciones del contrato social a partir de la propuesta hobbesiana, categorizadas hoy en día bajo el rótulo de contractualismo clásico. Dentro de tales propuestas se sostiene que fue con Rousseau con quien el contrato social alcanzó su momento de plena madurez, racionalizándose y profundizándose sus consecuencias democráticas. Así pues, el contrato social es —dentro de la filosofía política— el elemento más significativo para sustentar la teoría del Estado moderno. (...) Sin embargo, una importante consecuencia de dicha teorización es el hecho de que el naciente Estado moderno detente para sí el monopolio de la violencia. Así pues, es posible que un obscuro trasfondo de violencia se oculte tras la formulación contractualista. El artículo que sigue pretende desarrollar un análisis de la teoría del contrato social, particularmente en la formulación de Rousseau, a partir de la teoría mimética de René Girard, con el objetivo de encontrar en su obra más representativa El contrato social, rastros de la violencia mimética y el mecanismo de chivo expiatorio planteados en la teoría girardiana.

In this paper I challenge the notion that a healthy and resilient coral is (in all cases) a fast‐growing coral, and by inference, that a reef characterised by a fast trajectory toward high coral cover is necessarily a healthy and resilient reef. Instead, I explain how emerging evidence links fast skeletal extension rates with elevated coral‐algae (symbiotic) respiration rates, most‐often mediated by nutrient‐enlarged symbiont populations and/or rising sea temperatures. Elevated respiration rates can act to reduce the (...) autotrophic capacity (photosynthesis:respiration ratio) of the symbiosis. This restricts the capacity of the coral host to build and maintain sufficient energy reserves (e.g. lipids) needed to sustain essential homeostatic functions, including sexual reproduction and biophysical stress resistance. Moreover, it explains the somewhat paradoxical scenario, whereby at the ecological instant before the reef‐building capacity of the symbiosis is lost, a reef can look visually at its best and be accreting CaCO3 at its maximum.

Coral reefs provide substantial benefits to humans by generating biologically diverse ecosystems and reducing coastal hazards. However, in recent years, mass mortality of coral reefs due to bleaching has been witnessed in the ocean worldwide. Bleaching induced by the loss of the symbiotic relationship between algae and coral is mainly attributed to climate change. Marine protected areas (MPAs) can effectively prevent local disturbances but are less likely to conserve the coral reefs from global (...) events like climate change. Other conservation and restoration methods can be useful to protect and replenish the coral population temporarily, but whether they are feasible as sustainable conservation strategies is still equivocal. Coral reef mass mortality is not an exceptional occurrence but is linked to various instances of ecological loss, serving as an S.O.S. signal of severe prolonged climate extremes. (shrink)

Resumen La literatura universal, se encuentra poblada de arquetípicos que comparten una condición de desamparo y marginalidad, siendo la literatura realista de la segunda mitad del siglo XIX la que constata y da cuenta de su condición. En un mismo sentido, también la Biblia presenta un sinnúmero de personajes similares, marcando un punto de inflexión al llamarlo bienaventurados. Así pues, el presente estudio bíblico-literario, se centra en el arquetipo de la “viuda pobre”, sosteniendo dicha ficción literaria es una clave interpretativa (...) de la realidad, a la luz de la teoría literaria de la Estética de la Recepción. El articulo estudia la “viuda pobre” como un imaginario cultural y estableciendo la recepción de dicho imaginario en los cuentos “El Chiflón del diablo” y “El pago” del escritor chileno Baldomero Lillo, demostrando cómo el dialogo entre cultura y Biblia representa un aporte a la comprensión de determinadas ficciones literarias como categorías antropológicas.Universal literature is crowded by archetypical characters who share abandonment and marginalization conditions, being second half 19,h century realistic literature that confirms and exposes those conditions. In that sense, The Holy Bible presents a number of those characters. Resides, it highlights a turning point, hence, The Beatitudes point out: “Blessed are the poor in spirit, for theirs is the kingdom of heaven”. Thus, the following biblical-literary study, centered in the “Poor widow” archetype, aims to the establishment of literary fiction as interpretative key of reality, under Wolfgang Iser Aesthetics Reception's theory as its methodology. The objective aims to postulate “Poor Widow” as a Cultural imaginary, and finally to establish the reception of that imaginary within the stories “El Chiflón del Diablo” and “El Pago” by the chilean writer Baldomero Lillo, demonstrating that the dialog between culture and The Holy Bible represents a contribution to some literary fiction s as anthropological categories.

Companies are beginning to recognise the concept of Corporate Social Responsibility as presenting a new business model and an opportunity for building innovative forms of competitive advantage. Boards are instrumental in shaping and overseeing such strategies and active engagement around what it means to be a responsible and responsive enterprise can strengthen the Board's potential as a strategic influence on long-term value creation. Yet many companies align with Friedman's contention that adopting and practising CSR is a distraction from their core (...) obligation, which is to act in their shareholders' best interests. Based on directors' perceptions, the paper examines responses by Boards to socially related aspects of their governance role and reports on their external orientation and receptiveness toward wider social obligations. The findings suggest that these Boards hold a narrow view of their fiduciary duty, which is closer to the shareholder model than the stakeholder approach to corporate governance. (shrink)

Start-up organisations are small companies that experience a high level of growth and considerable risk to their very survival until they evolve into stable, established companies. This situation presents a particular set of challenges in terms of corporate governance, yet research on the governance of start-ups is limited. This research paper examines and comments on the governance of start-up organisations in New Zealand. The study replicates and extends previous New Zealand-based research of boards of established companies. From the data gathered (...) from the two surveys, conclusions can be drawn as to the role and focus of boards in start-ups versus established companies. The results are consistent with a model of active ownership which identifies key differences from established companies that could improve the governance of start-ups. The results also highlight the dependence of what might constitute effective corporate governance for a start-up on the strategic context of the company and its life cycle stage. (shrink)

Global concerns over environmental and social issues in agrifood value chains have increased and are reflected in a number of voluntary sustainability standards and regulatory initiatives. However, these initiatives are often based on poor knowledge of production realities, creating a disconnect between producing and consuming countries. Through narrative analysis, this paper reveals asymmetries in the responsibilities of the various actors participating in Ecuadorian banana value chains, providing clear problem- and solution-framings. Despite the broad range of actors interviewed, our analysis reveals (...) convergence in two main narratives that reflect asymmetries amongst local actors in terms of their ability to participate, ability to maintain participation, and adaptation strategies in view of changing external factors. One narrative relates to sustainability adaptations, the cost of which is not shared among all value chain actors. This is combined with a downward trend in the price of bananas and the lack of a differentiated price to account for losses and costs arising from increasing sustainability standards. Another narrative reflects a value chain structure that threatens small-farm survival. It highlights the urgency of protecting small-farm activity by enforcing national regulation and developing new market segments/models that understand small-scale producer reality. Study results show that the multitude of standards is not seen as beneficial and that downstream actors rather wish for common minimum standards to reduce business costs. Compatibility between standards and local realities should be a priority for global sustainability standards adoption. Building on the problems and solution-framings of local value chain links, we give voice to local actors, and link their perceptions to existing literature and discursive politics while contributing to social transparency and addressing the democratic deficit in agrifood value chains.

Animals use their chemosensory systems to detect and discriminate among chemical cues in the environment. Remarkable progress has recently been made in our knowledge of the molecular and cellular basis of chemosensory perception in insects, based largely on studies in Drosophila. This progress has been possible due to the identification of gene families for olfactory and gustatory receptors, the use of electro‐physiological recording techniques on sensory neurons, the multitude of genetic manipulations that are available in this species, and insights from (...) several insect model systems. Recent studies show that the superfamily of chemoreceptor proteins represent the essential elements in chemosensory coding, endowing chemosensory neurons with their abilities to respond to specific sets of odorants, tastants or pheromones. Investigating how insects detect chemicals in their environment can show us how receptor protein structures relate to ligand binding, how nervous systems process complex information, and how chemosensory systems and genes evolve.

ArgumentWhat does “life” become at a moment when biological inquiry proceeds by manufacturing biological artifacts and systems? In this article, I juxtapose two radically different communities, synthetic biologists and Hyperbolic Crochet Coral Reef crafters (HCCR). Synthetic biology is a decade-old research initiative that seeks to merge biology with engineering and experimental research with manufacture. The HCCR is a distributed venture of three thousand craftspeople who cooperatively fabricate a series of yarn and plastic coral reefs to draw attention (...) to the menace climate change poses to the Great Barrier and other reefs. Interpreting these two groups alongside one another, I suggest that for both, manufacturing biological artifacts advances their understandings of biology: in a rhetorical loop, they build new biological things in order to understand the things they are making. The resulting fabrications condense scientific and folk theories about “life” and also undo “life” as a coherent analytic object. (shrink)

This paper explores the ways in which neoliberal schooling is threatening education. We define education as the development of cognitive and imaginative capacities for understanding of and critical engagement with social reality. Education opens horizons of possibility for collective and individual life-experience and activity by exposing the one-sidedness and contradictions of ruling-value systems. Schooling, by contrast, subordinates thought and imagination to the reproduction of the ruling money-value system, narrowing horizons of possibility for collective and individual life to service to the (...) prevailing structure of power. Our paper draws on our overlapping experiences as educators, one in the university system, the other in the adult education system. In both systems, students’ life-requirement for education is subordinated to the capitalist need for compliant wage-labourers and consumers. In opposition to this instrumentalization we will present an interpretation of “real world education” as a unique form of collective work through which teachers and students construct alternatives that can serve as the guiding ideas for new projects for social and political transformation.

Tissues are shaped and patterned by mechanical and chemical processes. A key mechanical process is the positioning of the mitotic spindle, which determines the size and location of the daughter cells within the tissue. Recent force and position-fluctuation measurements indicate that pushing forces, mediated by the polymerization of astral microtubules against­ the cell cortex, maintain the mitotic spindle at the cell center in Caenorhabditis elegans embryos. The magnitude of the centering forces suggests that the physical limit on the accuracy and (...) precision of this centering mechanism is determined by the number of pushing microtubules rather than by thermally driven fluctuations. In cells that divide asymmetrically, anti-centering, pulling forces generated by cortically located dyneins, in conjunction with microtubule depolymerization, oppose the pushing forces to drive spindle displacements away from the center. Thus, a balance of centering pushing forces and anti-centering pulling forces localize the mitotic spindles within dividing C. elegans cells. We discuss microtubule-based mechanisms of the mitotic spindle positioning, a key mechanical process that shapes and patterns tissues. The magnitude of the centering forces indicates that the physical limit on the accuracy and precision of centering is set by the number of contributing microtubules rather than by thermally driven fluctuations.

Coral reefs have been challenged by the current rate and severity of environmental change that might outpace their ability to adapt and survive. Current research focuses on understanding how microbial communities and epigenetic changes separately affect phenotypes and gene expression of corals. Here, we provide the hypothesis that coral‐associated microorganisms may directly or indirectly affect the coral's phenotypic response through the modulation of its epigenome. Homologs of ankyrin‐repeat protein A and internalin B, which indirectly cause histone (...) modifications in humans, as well as Rv1988 histone methyltransferase, and the DNA methyltransferases Rv2966c, Mhy1, Mhy2, and Mhy3 found in coral‐associated bacteria indicate that there are potential host epigenome‐modifying proteins in the coral microbiome. With the ideas presented here, we suggest that microbiome manipulation may be a means to alter a coral's epigenome, which could aid the current efforts to protect coral reefs.

Addiction is increasingly described as a “chronic and relapsing brain disease”. The potential impact of the brain disease model on the treatment of addiction or addicted individuals’ treatment behaviour remains uncertain. We conducted a qualitative study to examine: (i) the extent to which leading Australian addiction neuroscientists and clinicians accept the brain disease view of addiction; and (ii) their views on the likely impacts of this view on addicted individuals’ beliefs and behaviour. Thirty-one Australian addiction neuroscientists and clinicians (10 females (...) and 21 males; 16 with clinical experience and 15 with no clinical experience) took part in 1 h semi-structured interviews. Most addiction neuroscientists and clinicians did not uncritically support the use of brain disease model of addiction. Most were cautious about the potential for adverse impacts on individuals’ recovery and motivation to enter treatment. While some recognised the possibility that the brain disease model of addiction may provide a rationale for addicted persons to seek treatment and motivate behaviour change, Australian addiction neuroscientist and clinicians do not assume that messages about “diseased brains” will always lead to increased treatment-seeking and reduced drug use. Research is needed on how neuroscience research could be used in ways that optimise positive outcomes for addicted persons. (shrink)

The diploblastic Cnidaria form one of the most ancient metazoan phyla and thus provide a useful outgroup for comparative studies of the molecular control of development in the more complex, and more often studied, triploblasts. Among cnidarians, the reef building coral Acropora is a particularly appropriate choice for study. Acropora belongs to the Anthozoa, which several lines of evidence now indicate is the basal class within the phylum Cnidaria, and has the practical advantages that its reproduction is predictable, external (...) and accessible and that the base content of its genome is not strongly biased. The Acropora system has already provided insights into ancestral linkages of homeobox genes and the evolution of the Pax genes, and has the potential to provide further new perspectives on the age, role in development, and evolution of these and other gene families.

As is well known, A. C.

There\nbegan Haddon’s ’conversion’ from zoology to anthropology.’ It seems that\nHaddon felt an urgent need to collect ethnographic information on the islanders\nbecause he saw they were changing and diminishing in number very quickly, and\ntherefore their customs were vanishing.\nVery (...) soon after my arrival in the Straits I found that the natives of the\nislands had of late years been greatly reduced in number, and that, with the\nexception of but one or two individuals, none of the white residents knew\nanything about the customs of the natives, and not a single person cared\nabout them personally. When I began to question the natives I discovered\nthat the young men had a very imperfect acquaintance with the old habits\nand beliefs, and that only from the older men was reliable information to be\nobtained. So it was made clear to me that if I neglected to avail myself of the\npresent opportunity of collecting information on the ethnography of the\nislanders, it was extremely probable that that knowledge would never be\ngleaned - for if no one interested himself in the matter meanwhile, it was\nalmost certain that no trustworthy information could be collected in, say, ten years’ time. This being my opinion, I felt it my duty to fill up all the\ntime not actually employed in my zoological researches in anthropological\nstudies. (shrink)

Australia does not allow adult smokers to buy or use electronic nicotine delivery systems that contain nicotine without a prescription. This paper critically evaluates the empirical and ethical justifications provided for the policy by Federal and State governments, public health advocates and health organisations. These are: that ENDS should only be approved as products for smoking cessation when there is evidence from randomised controlled trials that they are effective; that as a matter of precaution we should not allow the sale (...) of ENDS to smokers as consumer products because we do not know what their long-term effects will be; and that allowing ENDS to be sold as consumer goods will enable the tobacco industry to market ENDS to young people which will also lead to an increase in youth smoking. We show that the arguments and evidence offered in support of all these claims is very weak. We also argue that even if the evidence were stronger, it would not justify denying adult smokers the right to use ENDS either to quit smoking or as a long-term alternative to smoking cigarettes. We outline ENDS policies that would more ethically address the public health concerns that motivated the current policy by allowing adult smokers to access ENDS for smoking cessation or tobacco harm reduction under tight regulations that discourage commercial promotion and adolescent use.

In this paper I argue that the value attributed to coral reefs drives the characterisation of evidence for their regeneration or degradation. I observe that regeneration and degradation depend on an understanding of what an ecosystem looks like when undegraded (a baseline), and that many mutually exclusive baselines can be given for any single case. Consequently, facts about ecological processes are insufficient to usefully and non-arbitrarily characterise changes to ecosystems. By examining how baselines and the value of (...) class='Hi'>reefs interact in coral and algal reef examples, I argue that considering the value of an ecosystem is a necessity when describing processes like regeneration and degradation. This connects value as studied in socio-ecological and economic research with values as discussed in the philosophy of science literature. It also explains why such a broad range of processes may be considered regenerative, including those which introduce significant novelty, as well as pointing towards ways to mediate related debates, such as those surrounding novel and ‘pristine’ ecosystems.

"More than any thing else technology creates our world. It creates our wealth, our economy, our very way of being," says W. Brian Arthur. Yet, until now the major questions of technology have gone unanswered. Where do new technologies come from -- how exactly does invention work? What constitutes innovation, and how is it achieved? Why are certain regions -- Cambridge, England, in the 1920s and Silicon Valley today -- hotbeds of innovation, while others languish? Does technology, like biological life, (...) evolve? How do new industries, and the economy itself, emerge from technologies? In this groundbreaking work, pioneering technology thinker and economist W. Brian Arthur sets forth a boldly original way of thinking about technology that gives answers to these questions. The Nature of Technology is an elegant and powerful theory of technology's origins and evolution. It achieves for the progress of technology what Thomas Kuhn's The Structure of Scientific Revolutions did for scientific progress. Arthur explains how transformative new technologies arise and how innovation really works. Conventional thinking ascribes the invention of technologies to "thinking outside the box," or vaguely to genius or creativity, but Arthur shows that such explanations are inadequate. Rather, technologies are put together from pieces -- themselves technologies -- that already exist. Technologies therefore share common ancestries and combine, morph, and combine again to create further technologies. Technology evolves much as a coral reef builds itself from activities of small organisms -- it creates itself from itself; all technologies are descended from earlier technologies. Drawing on a wealth of examples, from historical inventions to the high-tech wonders of today, and writing in wonder fully engaging and clear prose, Arthur takes us on a mind-opening journey that will change the way we think about technology and how it structures our lives.

Children and adults alike stand awed before aquarium shark tanks, fascinated by the giant teeth and unnerving eyes. And no swim in the ocean is undertaken without a slight shiver of anxiety about the very real—and very cinematic—dangers of shark bites. But our interactions with sharks are not entirely one-sided: the threats we pose to sharks through fisheries, organized hunts, and gill nets on coastlines are more (...) deadly and far-reaching than any bite. In Sharks and People acclaimed wildlife photographer Thomas Peschak presents stunning photographs that capture the relationship between people and sharks around the globe. A contributing photographer to National Geographic, Peschak is best known for his unusual photographs of sharks—his iconic image of a great white shark following a researcher in a small yellow kayak is one of the most recognizable shark photographs in the world. The other images gathered here are no less riveting, bringing us as close as possible to sharks in the wild. Alongside the photographs, Sharks and People tells the compelling story of the natural history of sharks. Sharks have roamed the oceans for more than four hundred million years, and in this time they have never stopped adapting to the ever-changing world—their unique cartilage skeletons and array of super-senses mark them as one of the most evolved groups of animals. Scientists have recently discovered that sharks play an important role in balancing the ocean, including maintaining the health of coral reefs. Yet, tens of millions of sharks are killed every year just to fill the demand for shark fin soup alone. Today more than sixty species of sharks, including hammerhead, mako, and oceanic white-tip sharks, are listed as vulnerable or in danger of extinction. The need to understand the significant part sharks play in the oceanic ecosystem has never been so urgent, and Peschak’s photographs bear witness to the thrilling strength and unique attraction of sharks. They are certain to enthrall and inspire. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Experiences of MortalityPhenomenology and AnthropologyAlphonso LingisMartin Heidegger set out to elucidate our experience of being mortal, beneath the interpretations that he would take as metaphysical. He dismissed the dying that Socrates had taken to be liberation, a transfiguration, a passage to a higher kind of existence. Yet Socrates had argued that this liberation is an experience, anticipated in the asceticism of the body that is the very practice of (...) philosophy.Anxiety and NothingnessHeidegger finds my experience of my mortality in anxiety, which, he says, anticipates my experience of dying. He interprets anxiety to reveal that my dying is passage from existence to nothingness, annihilation; it is annihilation, for me, of the world about me. Heidegger confronts humans with their mortality in the most radical sense, forcing us each to see that our death is pure nothingness, that we are destined to be nothing. Humans are, through and through and in their most essential definition, "the mortals."Anxiety can be fled or covered over. But when acknowledged and accepted, it converts, Heidegger says, into resoluteness. Feeling myself adrift in the void, nothing supporting me, nothing to hold on to, I am thrown back upon the powers that still subsist in me, the powers that are my own. No longer counting on the support of the world or of others, taking up the powers that are my own, I now resolutely act on my own, exist on my own. Thus Heidegger sees the most negative experience, the experience of nothingness itself, converting into the most positive experience, the experience that posits my existence on its own.But does anxiety really identify death to be nothingness? What is distinctive of anxiety, as contrasted with fear, is that anxiety has no identifiable object. [End Page 69] It is a foreboding concerning what is indeterminate. What I am anxious about is the unknown—not something that I know to be nothingness.We could compare the situation that arouses anxiety with our edginess in the night. What makes the night disquieting is not a perception of something dangerous but the fact that possible dangers are not localizable in things. We no longer perceive things; their contours are dissolved by the night. But this no-thingness is not nothingness; there is left the darkness of night, which fills space, and invades, is within as much as without. The dissolution of contours and boundaries makes whatever dangers the night harbors be possibly anywhere, everywhere.The deep uneasiness before the unknown that afflicts me does not turn into a recognition that I exist on my own and can, must, act on my own. I would instead overcome, or at least endure, anxiety by seeking support in what is known, even though it is now out of reach.The fact that death is not evidently nothingness, that anxiety is not experienced as manifestly a sinking into nothingness but rather as a foreboding regarding what is unknown, ungraspable, motivates the efforts, in so many cultures, to know what the state of death is.Anxiety, Heidegger observes, can be fled or covered over, and it is so concealed in everyday preoccupations. But when we see that death is unmistakably imminent, our existence would be nothing but the dull pounding of anxiety, driving the resolute plunge into nothingness. Yet anthropological research in many cultures, including our own, has shown that many people sink calmly and peaceably into death, and many cultures have elaborated practices that help people to die without anxiety. The Tibetan Book of the Dead is an example.We have had a premonition of this calm. When we go to the forests and the meadows, to mountains and glaciers, when we descend into the coral reefs of the oceans, when we contemplate the movements of the clouds, we find ourselves not in the Heideggerian "world" of implements and objectives, pathways and obstacles, but in nature. A nature that we are not surveying with a circumspection governed by our interests; our gaze drifts among beings, seeing them as they are, as they exist on their own. There is a dissolution of any governing and integrating force in our consciousness, and the systole and diastole of our consciousness disconnect... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Ethics & the Environment 8.2 (2003) 8-30 [Access article in PDF] Dialogue, Responsibility, and Oil and Gas Leasing on Montana's Rocky Mountain Front Scott Friskics "How does nature speak to our concern? That is the question" (Bugbee 1978, 11). It's a late afternoon in mid-March and I'm standing outside my friends' house on the southwest edge of Augusta, Montana, a small town of about 500 residents. I'm here to (...) meet a companion who's headed out from Great Falls to spend the weekend at my cabin, which is located up in the mountains approximately 20 miles west of here. As is often the case, I'm a bit early for our rendezvous. Blame it on unbridled anticipation or a latent preoccupation with punctuality, but my premature arrival offers me a few stolen moments of enforced inactivity with which I can revel in the sensory fullness of a pleasant, pre-spring afternoon.Out here on the plains, spring seems much nearer at hand than it does back up in the mountains. The air's still cool and the wind still bites, but the warm afternoon sun embraces me and unlocks a host of smells long-held in winter's freeze: earthy mud puddles, sweet horse manure, damp hay. [End Page 8]While waiting, I wander over to the nearby corral to greet three gentle, mud-splattered horses. As I absently rub their chins and stroke their long, slender noses, I gaze out beyond the horses, out beyond the soupy corral, beyond the expanse of wrinkled, sere, brown plains. My eyes focus on the blue-shadowed wall of mountains from which I've just emerged: Montana's Rocky Mountain Front. From this vantage point, the Front presents itself as a horizon-filling tidal wave of rock—fluid, walking mountains that, over the course of their long march through time, have been thrust skyward and pushed eastward to where their easternmost reefs and ridges now hang precipitously over the wide expanse of the northern Great Plains.Dead center in my line of vision stands the tilted summit of Crown Mountain—the univocal, eloquent peak that towers about the narrow mountain valley where I live, provides me with the ultimate spatial reference point for my life, and fills my days with the gracious bounty of its abiding presence. From here, however, Crown Mountain presents itself to me not so much as a soloist, but rather as one voice in a chorus of mountain song. Working southward from this orienting center, I encounter Crown Mountain's nameless twin and the rocky ridge line descending to Welcome Pass, above the notch of which rises the deceptively unassuming head of the Scapegoat Massif. Much nearer at hand and dominating the foreground stands the dark cone of Haystack Butte—an intrusive igneous island in a sea of sedimentary mountains. Further south runs the high ridge guarding the headwaters of the Dearborn River, with Steamboat Mountain rising above the rugged country drained by Elk Creek, Blubber Creek, Falls Creek, Cuniff Creek.Working northward from the crown, the mountains are no less spectacular, no less evocative: the slanting summit of Fairview Mountain, the jagged gray wall of Sawtooth Ridge, the low gap of Sun Canyon (where the united Sun River flows out onto the plains and benches of central Montana), the flattened rock face of Castle Reef, and, framing the northern edge of my vista, the rising bulk of Ear Mountain. Of course, standing here in Augusta I'm well aware that what I can see from this spot is less than half of the Front, so my imagination continues north to Blackleaf Canyon, the Birch Creek country, the Badger-Two Medicine, the east slopes of Glacier National Park, and that holy border sentinel, Chief Mountain.I first saw this glorious stretch of country on a blustery November day 16 years ago, and I have yet to encounter another place that speaks to me with such force and beauty, such overwhelming, undeniable eloquence. [End Page 9] And, on this soul-stirring March afternoon, the... (shrink)

Siphonous seaweeds, which constitute a vital component of coral reefs, are structurally simple, single‐celled coenocytic macroscopic green algae. Kim et al.1 have recently shown the extraordinary wound‐repair and propagation mechanism of one such siphonous green alga—Bryopsis plumosa. Nucleocytoplasmic aggregates, which are released after injury to this plant, are membraneless structures that can survive in seawater for 10–20 minutes, before they are surrounded by a gelatinous envelope. Subsequently, a cell membrane and cell wall are synthesized around each of these (...) aggregates and the resulting individual cells, so formed, develop into new plants. This report represents a significant advance in our understanding of wound response and, more significantly, is probably the first example of transient survival of life without a cell membrane!
