South Africa’s groundbreaking constitution explicitly confers a right of access to sufficient water. But the country is officially ‘water-stressed’ and around 10 % of the population still has no access to on-site or off-site piped or tap water. It is evident that a disconnect exists between this right and the reality for many; however the reasons for the continuation of such discrepancies are not always clear. While barriers to sufficient water are myriad, one significant factor contributing (...) to insufficient and unpredictable access to water is the high percentage of broken water pumps. Previous studies have reported that between 20 and 50 % of all hand operated water pumps installed on the African continent are broken, or out of use. Monitoring and maintenance of pumps, which in South Africa is the responsibility of local municipalities is often ineffective, in part due to the distances between municipal centres and rural communities and the consequent costs of site visits, as well as breakdowns within the local bureaucratic system. The emergence of new telemetry tools that can remotely monitor water applications constitutes a novel and cost-efficient alternative to undertaking regular sites visits. Sustainable, appropriate, low-cost telemetry systems are emerging that could be used to monitor the operational performance of water pumps, or a wide range of other field parameters, and to communicate this information swiftly and cheaply to water service providers, using SMS messages. Data on the performance of water pumps could also be made available to the public online. This is an example of how ICT can be used for water resources management and environmental regulation, as well as in the governance of socio-economic rights: helping to optimize water allocation by improving communication and strengthening accountability.

The removal of water from mines was one of the key issues that former miners had to deal with. Roman colonists brought new technology to the Iberian Peninsula that addressed this problem. However, they did not invent this technology because it had already been applied to the growth of other endeavours in the Hellenistic society throughout the Eastern Mediterranean. In the mine, the Archimedes screw, waterwheels, bucket pulleys, and Ctesibius pumps were the primary drainage systems. In this essay, the (...) primary characteristics, and modes of operation of machines are examined. Without leaving out the most significant finds made in the southwest of the Iberian Peninsula, one of the regions with the longest history of mining exploitation. To serve as a foundation for future research in this field, this work compares the primary mining mechanisms in ancient Huelva on a qualitative and quantitative level by the implementation of a TOPSIS methodology, a multi-criteria decision analysis method.

In lieu of an abstract, here is a brief excerpt of the content:A Reciprocating Engine--Like ProustRoger ShattuckWould you buy a book called “How to Read a Book”? Only out of annoyance, I imagine. In the company of literary scholars, critics, and writers, we all think we know already how to read. Otherwise, we’d be professional charlatans. Still, in 1940 tens of thousands of people bought a book called How to Read a Book by Mortimer J. Adler. It stayed on the (...) best seller lists for several weeks. Adler wrote in an easy conversational style and promoted good books—even old ones. But he had the essentials wrong. He believed we should read the way a tyro tours an art museum: the tyro looks at the label before looking at the painting. Of course our whole educational system—K plus 12 plus 4 plus even more—inevitably follows this label-first method. I shall come back to the basic question of order of events in reading literature.On the basis of my own experience and of my investigations in recent years, I distinguish three kinds or levels of reading. We read for basic comprehension of words and sentences. We read for literary response to the parts and the whole of a work. And we read for the relations of the work to other works and to life itself. These tentative categories of reading do not represent sequential stages. Our response to language may resort to one or all of these three activities at any stage of learning.Formal reading begins with the basic association of written word with sounded word—with a notion in the mind—with some phenomenon in the world. Since most of us have forgotten how we learned those initial associations, we understand them probably from having helped a child to read. And in that gradual process we do not usually encounter the excitement that can occur when an illiterate older child or an illiterate [End Page 104] adult suddenly grasps the miracle of language. The exemplary case of Helen Keller concentrates into one incident at the water pump the revelation that comes to the rest of us over a period of weeks or months at a much earlier age. We should never forget one fundamental: the comprehension stage of reading is not an empty skill that can be acquired apart from meaningful content. In order to make sense of written language, we cannot just learn a mental trick of association but must also acquire much information about the world we live in.This first category of reading for comprehension is endlessly debated by all parties, including literary scholars and critics. Almost no one speaks of the third category: how to keep track of and make use of what we read over the years, both as professionals in the field of literature and as individuals seeking to shape a life out of our experience. I lifted the title of this panel from a remarkable essay on how to keep notes on one’s reading and how to set up and constantly revise a system of files both in order to give direction to one’s professional career and in order to constitute one’s character as a person. The essay “On Intellectual Craftsmanship” was written by C. Wright Mills as an appendix for The Sociological Imagination (1959). We all pick up procedures for keeping notes and files as we go along. But despite the number of methodology courses in graduate programs in literature, such basics are rarely discussed. Mills deserves much credit for raising a neglected subject essential for all writers. Intellectual craftsmanship will become even more challenging in the era of electronics and computers.Another great scholar a century earlier saw fit to speak of these basics near the end of his autobiography.I may mention that I keep from thirty to forty large portfolios, in cabinets with labelled shelves, into which I can at once put a detached reference or memorandum. I have bought many books and at their ends I make an index of all the facts that concern my work; or, if the book is not my own, write out a separate abstract, and of such abstracts I have a huge drawer...

We propose capability as a universal or type intermediate between function and disposition. A capability is, broadly speaking, a disposition that is of a type whose instances can be evaluated on the basis of how well they are realized. A function, on the view we are proposing, is a capability the possession of which is the rationale for the existence of its bearer. To say for example that a water pump has the function to pump water (...) is to say that the pump exists because something was needed that would pump water. A water pump may have many capabilities, including: to be weatherproof, to run without lubricant, to be transportable, and so forth. But its function is to pump water. We focus here on capabilities possessed by humans – such as piano playing or language using – and we explore the relation between capabilities of these sorts and structures in the brain. (shrink)

Extensive scientific, philosophical and artistic activities were carried out in the Islamic World’s various science and civilization centers during the early Middle Ages. In these centers, noteworthy works of mathematics, astronomy, geography, medicine, pharmacology, optics, botany, chemistry and other fields of science, which would later determine improvement paths for these fields, were created. Abu al-Izz Ismail ibn al-Razzaz al-Jazari (12th-13th centuries), was a magnificent Muslim scientist known for his work named The Book of Knowledge of Ingenious Mechanical Devices (Kitab fi (...) ma‘rifati’l-hiyal al-handasiyya) and he was born in geography where many scientists were trained. He contributed to the development of science and civilization, the joint legacy of humanity and demonstrated his true capability and success in the field of ilm al-hiyal (the scientific field which addresses the information and practices regarding mechanical technology and engineering in Islamic science history). From this perspective, it is evident that al-Jazari had a wide field of interest, made his mark in the age he lived in with his brave and innovative ideas, and was a wise engineer. al-Jazari’s detailed descriptions and explanations of water clocks, oil lamp clocks and water pumping machines, as well as their construction, were astounding. In addition, al-Jazari’s studies on metal casting techniques, cone valves, wheel balance and the real-world use of aspiration tubes are important in contemporary engineering studies. When all these are considered, it becomes clear that his designation as the “Leonardo da Vinci of the Islamic World” is not a coincidence. Many studies on al-Jazari’s scientific legacy have been conducted in various parts of the world. There are various manuscripts of his aforementioned book. Based on these manuscripts, the work has been -fully or partially- translated into many languages, including Turkish. The German and English translations served as a basis for studies on al-Jazari in other languages. In recent years, studies conducted on al-Jazari in Türkiye (books, articles, domestic and international symposiums, congresses etc.) have demonstrated his brilliance and competence as a scientist. Furthermore, studies on al-Jazari are still ongoing in Türkiye. As for Russia, the scientific legacy of the scientists raised in the Islamic World such as Avicenna, al-Farabi, Abu Bakr al-Razi, Abu Rayhan al-Biruni, Abu al-Qasim al-Zahrawi, Muhammad ibn Musa al-Khwarizmi, al-Battani, al-Kashi, Abd al-Rahman al-Khazini, Nasir al-Din al-Tusi was researched within the scope of a special plan and program. Depending on the relevant studies, al-Jazari and his work drew attention as well. A small portion of the aforementioned Russian studies is known in Türkiye. It is safe to assume that al-Jazari studies in Russia are virtually unknown in Türkiye. The present study primarily aims to contribute to the literature on the scientific legacy of al-Jazari, a Middle Age Islamic scientist best known for his famous work in the mechanical field. More specifically, the present study aims to: 1) to identify the studies on al-Jazari in Russia, and in the former USSR countries, where academic studies are still in Russian after the Soviet Union period, to create a chronological biography and to set forth their compilation; in other words, to create a bibliography which includes Russian studies on al-Jazari; 2) to provide information on the structure and content of the studies in question, to detect the methodological issues encountered in these works, and make solution recommendations to solve these issues; 3) to contribute to continuing and future studies in Türkiye on al-Jazari in terms of source and material index. In conclusion, it should be stated that comparative reading was conducted centered on The Book of Knowledge of Ingenious Mechanical Devices (Kitab fi ma‘rifati’l-hiyal al-handasiyya). It should also be noted that Russian popular internet publications (which are not based on academic research and are created/reproduced for commercial and personal purposes) were excluded from the assessment.

We propose a definition of capability as a class intermediate between function and disposition as the latter are defined in Basic Formal Ontology (BFO). A disposition inheres in a material entity and is realized in a certain kind of process. An example is the disposition of a glass to break when struck, which is realized when it shatters. A function is a disposition which is (simply put) the rationale for the existence of its bearer. To say for example that a (...) water pump has the function to pump water is to say that the pump exists because something was needed that would pump water. Capabilities are a special sort of disposition in that that, like functions, they can be evaluated on the basis of how well they are realized. They differ from functions in that their realizations are not the rationale – not the primary reason – for the existence of their bearers. Thus, a water pump may have many capabilities, including to be weatherproof, to run without lubricant, and so forth, but only one function. All functions are capabilities on the view we defend, but not all capabilities are functions. We develop a series of axioms to distinguish capabilities formally from both dispositions and functions and provide examples of the use of ‘capability’ in a variety of domains. (shrink)

Bruises on my shoulder from carrying books and notebooks, pencils and crayons. Pebbles crunch. An engine grinds, brakes screech. I step into a cloud of pink dust and weeds.

Feathers of a bent blue bird impale the road. Sun beats the crushed bird. Cutting through the tall, tall grass, I pick up a stick to warn. Songs and sticks have power over snakes. Bramble snaps. Wild berries squish under my feet. The ripe scent makes my belly grumble. Briar thorns prick my skin, making my fingertips bleed. Plucking handfuls, I eat. Blood on a blackberry ruins its taste.

In lieu of an abstract, here is a brief excerpt of the content:Ethics & the Environment 12.2 (2007) 128-130MuseSearchJournalsThis JournalContents[Access article in PDF]The Future of Environmental PhilosophyIrene J. KlaverEnvironmental philosophy is invitational: it in-vites thinking into life as well as life into thinking. Life is vita in Latin—the same vita as in vital and in vitamins. An in-vita-tion leads to new connections, or a renewal of existing relations. This affects how we understand things. As Wittgenstein says, "understanding [...] consists in (...) the very fact that we 'see connections.'"1 This is the case for philosophy in general, it makes connections, reveals relations between entities, thoughts, and events, which elucidates our understanding. Environmental philosophy has (re-)opened certain realms of relevance to philosophical inquiry by foregrounding our connections to the non-human world. It accommodates the broadest invitation: of life itself, including our relation to the conditions of life.The future of environmental philosophy lies precisely in this broad invitation. That means that it needs to occupy a profoundly interdisciplinary place, at the node of multiple institutions and practices. It deals with global issues on a local level and with the effects of local issues on a global scale. This involves science, policy, economy, law, ethics, aesthetics, religion, history, etc. An environmental philosopher is a specific generalist, someone who can connect various relations, sees the multiple angles in a particular perspective, the world in a grain of sand.The evolved environmental philosopher is a translator, translating various concerns along multiple perspectives. Translation is crucial to an understanding of the viewpoints, positions, and situations of others. Environmental philosophy enlarges the category of the "other" with many more entities. This is not a politically correct move to bring so-called repressed voices to the fore, it is to evoke different modes of knowledge and experience, to enhance cultural imagination2, a crucial component to raising awareness about environmental concerns.In her 1962 book Silent Spring3, Rachel Carson connected pesticide DDT to the decline in some predatory bird populations and sparked the rise of the environmental movement. She triggered a powerful cultural imagination by invoking a future silent spring without the singing of birds. Hegel saw the owl of Minerva as the symbol of wisdom, spreading "its wings only with the falling of the dusk."4 That is, for Hegel understanding arises after the events, philosophy can never be prescriptive. [End Page 128] Environmental philosophy, on the contrary, is engaged thinking, its understanding arises out of the practices of the everyday. The albatross around our neck is of our own shooting. Environmental ethics and environmental justice might stake out basic prescriptive rules, but these are always born from knowledge of—if not a participation in—certain practices. Environmental philosophy's bird is the spotted owl of social-political engagement, the canary in the mineshaft, but also the sparrow in the backyard. Birds that fly from dawn to dusk, seeing and reporting in the light the practical connections that reveal understanding, possible action, communication needs, and suggest a lexicon for translation. In and through practical connections rises therefore translation and understanding.Understanding is a transformative process—it changes our interpretative frameworks. When we see connections we begin to understand how the dead zone in the Gulf of Mexico is related to agriculture in the midwestern United States thousands of miles away, with watersheds within the Mississippi River Basin draining nitrogen fertilizers into the Mississippi, causing hypoxia in the Gulf.5 Environmental philosophy shows how wetlands are not just wastelands but take nitrogen and phosphorus out of the water, buffer "our" coasts, and feed the migrating birds along their long routes. By not seeing these connections, our wetlands are pumped dry; and by abusing our water, springs disappear, major rivers strand in sand, and dead zones emerge in oceans and seas. "These, too, were silent, deserted by all living things," Rachel Carson states, writing about streams.6 In the twenty first century it is no longer a "fable of tomorrow:" silent springs, silent rivers, silent seas.Environmental philosophy is empirical philosophy dealing with big issues such as global warming, biodiversity, and sustainability, but...

In 1662 Christiaan Huygens carried out the famous Torricelli experiment to test the existence of atmospheric pressure by inserting the apparatus in the glass receiver of a vacuum pump, and evacuating the air inside it. He reported that when the air was exhausted, a column of water remained suspended in a 4-foot tube. This unexpected result was in stark contrast with earlier experiments of Boyle and Hooke that apparently had confirmed Torricelli’s explanation that such a water column (...) was supported by outside air pressure, and would fall when the air was removed. Huygen’s “anomalous suspension” led to the continuation of controversies in the seventeenth century about the nature of the vacuum that these experiments were expected to resolve. Surprisingly, the origin of Huygens’ unexpected result has remained a puzzle up to the present time. In this paper, I discuss the dynamics of such a column of water under the experimental conditions reported by Boyle and by Huygens, that turned out to be different, and present the results of a replication of their experiments with a modern vacuum pump. Contrary to the conventional explanations of these experiments, I demonstrate that in the Boyle–Hooke version of this experiment, the water column descends initially because it is forced down by the gas pressure due to air dissolved in the water which is released inside the Torricelli tube after the external pressure is sufficiently decreased. Huygens, however, first removed this trapped air before he carried out his experiment. In the absence of this internal gas pressure, the early rudimentary vacuum pumps were inadequate to decrease the air pressure sufficiently inside the receiver to demonstrate the descent of a Torricelli column of airless water 4-foot in height or less.

Human agency is typically thought of as intentional, purposeful, reflective and, in many cases, autonomous. This paper discusses human agency that is compromised in some of these respects, and actions that are actions only in a qualified sense. The object of study is the agency of the leading character, Jeff, in the film noir Out of the Past, and Elizabeth Anscombe’s Intention is the primary source in analyzing Jeff’s behavior.Two excerpts from the film are presented and analyzed. The analysis of (...) the first excerpt reveals agency that is merely weakly intentional; that is lacking in purposiveness and which displays ambivalence. Anscombe’s example of the man pumping water helps us see that Jeff’s actions are only intentional under some, basic, descriptions; that there is no intention of the action. Jeff does not really know his way about and his actions are not sufficiently grounded in reason. This, it is argued, is largely because he is not the author of his own actions: he is thrown into a situation set up by someone else. He enters in medias res and feels forced to act although he has limited knowledge of the meaning or purpose of the full action in which he partakes. In Anscombian vocabulary, he lacks the first-person practical knowledge typical of intentional action.In the second episode, Jeff protects Kathie the femme fatale, even when knowing that she has killed a man, stolen money, lied to Jeff, and is trying to frame him for murder. It is argued, in dialogue with Anscombe and Stoutland, that this case may be understood in terms of a mental cause rather than as an intentional action: Jeff’s actions and neglect to act is motivated by his passion for Kathie, it blinds him from considering what is reasonable and right to do.

Ground-coupled heating-cooling systems (GCHCSs) exchange heat between the built environment and the subsurface using pipework buried in trenches or boreholes. If heat pumps in GCHCSs are powered by “green electricity,” they offer genuine carbon-free heating-cooling; for this reason, there has been a surge in the technology in recent years. Interference between adjoining installations is being reported, raising issues of sustainability in terms of performance, equitable sharing of natural resources, and localized ecological impacts. Using an analytical model for heat transport in (...) porous media, sensitivity analyses have been obtained for open-loop systems in typical hydro-geological settings for urban GSHCSs in the United Kingdom, revealing that breakthrough of injected water will likely lead to significant declines in system performance in less than 25 years for well spacings less than 300 m, unless injection rates are kept below 250 m3/d. Only by cooperatively planning will adjoining landowners in urban areas achieve large-scale sustainable system designs. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:240 Feminist Studies 45, no. 1. © 2019 by Mary Anna Evans Mary Anna Evans Personal Continuum The scent of gasoline is neither attractive nor repulsive. It falls somewhere on the continuum between. It is medicinal, but without the acrid bitterness of medicine. It draws children like a drug, but only when their parents aren’t hovering to warn of danger. Adults know about fire and poisoning and long-range carcinogenic (...) doom. Children only know that the odor around gas pumps smells naughty and fun, until their lips open and the flavor of petroleum turns their stomachs. Why do some things smell so much better than they taste? Gasoline, unlike honey, draws humans but not flies. Sarah was not thinking of fire, poisoning, or doom when she fitted the long metal nozzle into the mouth of her car’s fuel tank. She was trying not to think at all, though the customary thoughts slipped in. None of them were about gasoline. The pump’s air pollution control system was working well but not perfectly, so it took a moment for the odor to reach her nose. Her body roused and snarled at her. The baby. What are you thinking? If you breathe those fumes, what will they do to the baby? A moment passed while her body checked itself, remembering what it already knew. There was no baby. Where is the baby? Mary Anna Evans 241 The frantic voice didn’t echo between her ears. It had nothing to do with her brain at all. It was more than thought. It came from a place deeper than thought, and it wasn’t hers. Her body said things she didn’t want to say, and it needed things she didn’t need. Her body wanted things that were not good for her. Again, Where is the baby? And then, the darker question. What did you do? “Nothing,” she said aloud, since there was no one to hear. I didn’t do anything but bleed. I’m still bleeding. She resisted the instinct to clap her hands over her ears to shut out the voice that couldn’t be shut out. Her defiant hold on the nozzle kept her upright. She listened to the rhythmic throb of the pump. Refusing to turn her face from the gasoline’s stench, she opened her mouth and let the fumes seep in. * * * “Hello, sweetheart,” Frederick said as he came in the door. His peck on the cheek didn’t linger, so Sarah knew there would be no more expressions of affection that day. He had read in a self-help book that it was important for couples to use terms of endearment as a form of bonding. Physical displays of affection were important, too, or so said the self-affirmed relationship expert who wrote the book. In public, displays of affection affirmed the pair bond. In private, even a quick smooch forced men and women to secrete an attachment chemical called oxy-whatever. Oh, hell. She was a chemist. She knew what oxytocin was. She was just mystified by the notion of reading a book to find out how to get some. He turned away and went into the kitchen to fetch the marinating chicken. He always grilled when it was his night to cook. She had come to wonder whether modern men were drawn to cook with fire by an ageold hunter instinct, or whether they were attracted to an activity that put a well-insulated exterior wall between them and the women who remained inside to toss the salads. All across America, every warm summer night, lonely women toss salads and hope for romance. His head poked in the back door. “I bought slivered almonds and croutons.” 242 Mary Anna Evans Her “Thanks for remembering, sweetheart,” bounced off the closing door. Shit. She could have spared herself that soulless term of endearment. Leaving the lettuce in the refrigerator, she thrust her soapy hands under warm running water, because even thinking the word “shit” made the idea of handling raw food appalling. Her body, which had forgotten again that she’d lost the baby, approved of her caution. She guarded her thoughts against disturbing its... (shrink)

The ability of trees to suck water from roots to leaves, sometimes to heights of over a hundred meters, is remarkable given the absence of any mechanical pump. This study deals with a number of issues, of both an historical and conceptual nature, in the orthodox ``Cohesion-Tension'' theory of the ascent of sap in trees. The theory relies chiefly on the exceptional cohesive and adhesive properties of water, the structural properties of trees, and the role of evaporation (...) from leaves. But it is not the whole story. Plant scientists have been aware since the inception of the theory in the late 19th century that further processes are at work in order to “prime” the trees, the main such process -- growth itself -- being so obvious to them that it is often omitted from the story. Other factors depend largely on the type of tree, and are not always fully understood. For physicists, in particular, it may be helpful to see the fuller picture, which is what this study attempts to provide in non-technical terms. (shrink)

Sometimes analogy researchers talk as if the freshness of an experience of analogy resides solely in seeing that something is like something else -- seeing that the atom is like a solar system, that heat is like flowing water, that paint brushes work like pumps, or that electricity is like a teeming crowd. But analogy is more than this. Analogy isn't just seeing that the atom is like a solar system; rather, it is seeing something new about the atom, (...) an observation enabled by 'looking' at atoms from the perspective of one's understanding of solar systems. The question for analogy researchers then is this: Where does this new knowledge about atoms come from? How can an analogy provide new knowledge and new understanding? (shrink)

The transition from a vague generalization to an accurate statement is the first step on the road to science. It is a step of great importance. Vague generalizations find a ready entrance into many minds, and produce a comfortable sense of satisfaction that is easily mistaken for knowledge, and that stops further questioning. An exact statement of fact, on the other hand, draws attention to detail, and shows itself to be set in a mass of further detail that it challenges (...) you to explore. “Nature abhors a vacuum” sounds final; it explains why water will rise in an ordinary suction-pump rather than allow a vacuum to be produced; why the schoolboy’s “sucker” will lift a stone; and many other phenomena of a similar kind. It explains everything by a phrase and stimulates no inquiry. But when Galileo noted that the pump would raise water only to a height of about 32 feet, and pointed out that this gives a measure of the extent to which Nature abhors a vacuum in its dealings with water, new questions arose, stimulating further investigation.

In their environment, plants are continuously submitted to natural stimuli such as wind, rain, temperature changes, wounding, etc. These signals induce a cascade of events which lead to metabolic and morphogenetic responses. In this paper the different steps are described and discussed starting from the reception of the signal by a plant organ to the final morphogenetic response. In our laboratory two plants are studied: Bryonia dioica for which rubbing the internode results in reduced elongation and enhanced radial expansion and (...) Bidens pilosa for which the response occurs at distance, hence pricking the cotyledon of a plantlet induces the growth inhibition of both the hypocotyl and the axillary bud of the pricked cotyledon. Reception of the signal and transmission of the message. In Bryonia the signal is received by epidermal cells while in Bidens they are the cells adjacent to the midrib of the cotyledon which receive the mechanical signal. In both plants the message is transmitted via a wave of electric depolarization. This latter is composed of an action potential associated with a slow wave whose transmission rates are respectively 1cm s−1 and 1 mm s−1. Recent results have shown the involvement of Ca2+ in the triggering of the slow wave and the role of the H+ pump during the slow wave. Transient and fast biochemical responses. An entry of extraceilular Ca2+ into the cells and a transient increase in IP3 occur within seconds following the mechanical stimulus. At the same time, the membrane becomes more fluid, correlated with qualitative changes in phospholipids. The rapid increase in the concentration of peroxidated lipids may be correlated with ethylene biosynthesis which is stimulated after rubbing. Other parameters such as cytoplasmic pH, relative water content, hydric potential, membrane potential and modifications of K+, Mg2+-ATPase and Ca2+-ATPase activities, play a key role in the early responses induced by the traumatisms. Irreversible-biochemical responses. The mechanical stimulus performed on a Bryonia internode induces an acceleration of: i) enzymatic activities related to the lignification, ii) esterification of phenolic acids in the cell wall. Consequently the lignification process is accelerated. Storage of the information. After being received by the target cells the information can be stored during several days before being expressed. At the level of cotyledonary bud, the first message, previously stored, can be expressed or not by a second treatment. Bidens thus behaves as if it was able to “store” and to “retrieve” morphogenetic messages, using a sort of rudimentary memory. The nuclei of the bud cells of the pricked cotyledon show that these cells, initially in G2 phase, divide and then remain in the G1 phase. In Bryonia, calli derived from young stimulated internodes, keep thigmomorphogenetic characteristics during several weeks. In the last part of this paper the particularity of our plant model which permits a study of the transmission and storage of the message, is underlined. The links between the different steps induced by the stimulus are discussed. Special attention is devoted to second messengers and to the amplification of the message. (shrink)

Contemporary philosophers of science argue that models are a major vehicle of scientific knowledge. This applies to highly theoretical inquiry as well as to experimental or otherwise observational research, in both the natural and the social sciences. Making this claim is not yet very illuminating, given that there is a large variety of different kinds of model, and a number of ways in which they function in the service of science. The ambiguity of the term ‘model’ and the multiplicity of (...) kinds of model are illustrated by Pierre Duhem’s famous comparison of the mind of a continental physicist to that of an Englishman: the former strives for ‘theories’ that are formulated in ‘the clear and precise language of geometry and algebra’ and consist of abstract and idealized notions and formulae, while the latter insists on having mechanical ‘models’ that satisfy ‘his need to imagine concrete, material, visible, and tangible things’ that are familiar to ordinary experience. While the French or German physicist deals with a formalized theory in his account of electrostasis, the English account is in terms of ‘strings which move around pulleys, which roll around drums, which go through pearl beads, which carry weights; and tubes which pump water while others swell and contract; toothed wheels which are geared to one another and engage hooks. We thought we were entering the tranquil and neatly ordered abode of reason, but we find ourselves in a factory’ (Duhem 1954, pp. 70–1). Models in this sense—iconic models —employ analogies to visualize the mechanisms depicted, while formalized theories supposedly lack this property. On the other hand, it is nowadays customary to use the term ‘model’ also for such formal systems of equations, conspicuously so in the social sciences—and, much of the time, such formal systems are used for representing causal mechanisms. In relation to such a formal system, ‘model’ is also used for its various interpretations, or just for the interpretation that makes it true. The model muddle needs to be sorted out. (shrink)

Ocean biology helps regulate global climate by fixing atmospheric CO2 and exporting it to deep waters as sinking detrital particles. New observations demonstrate that particle fragmentation is the principal factor controlling the depth to which these particles penetrate the ocean's interior, and hence how long the constituent carbon is sequestered from the atmosphere. The underlying cause is, however, poorly understood. We speculate that small, particle‐associated copepods, which intercept and inadvertently break up sinking particles as they search for attached protistan prey, (...) are the principle agents of fragmentation in the ocean. We explore this idea using a new marine ecosystem model. Results indicate that explicitly representing particle fragmentation by copepods in biogeochemical models offers a step change in our ability to understand the future evolution of biologically‐mediated ocean carbon storage. Our findings highlight the need for improved understanding of the distribution, abundance, ecology and physiology of particle‐associated copepods. (shrink)

continent. 2.2 (2012): 155–158 Michel Serres. Biogea . Trans. Randolph Burks. Minneapolis: Univocal Publishing. 2012. 200 pp. | ISBN 9781937561086 | $22.95 Conveying to potential readers the significance of a book puts me at risk of glad handing. It’s not in my interest to laud the undeserving, especially on the pages of this journal. This is not a sales pitch, but rather an affirmation of a necessary work on very troubled terms: human, earth, nature, and the problematic world we made. (...) It is this world that aspirates the silence (so to speak), and therefore the subject which, along with the development of the “made world” exports the excess augmentation of the cosmically missing, this silence of the natural, et cetera. Had we learned from Locke that lesson of “labor,” to consume what we need… but perhaps we need more than what matters? Serres’ Biogea has several functions on this manner, if it is indeed a book to be consumed. First, readers searching for novelistic entertainment have a place to dwell. Biogea deserves a place in your back pocket; biographical generosity and poetic fluidity should satisfy most textual fetishes. For lay philosophers who want to refresh their acumen, Biogea deserves a place on the book shelf, one already reads a sorely needed postmodern tune-up here. Serres’ style is clearly French; he leaves few cheese crumbs on his words, rather preciseness and breathing in the work give way to a sweeping manner that breaks the narrative line of sight. A circular narrative and anachronistic fragmentation of terms allows an abyssal atmosphere to swell, if only to pump into the book the externality of its broader text. Biogea aspires to a higher standard and the book, at times, is thinking this negentropic problem too. Univocal, the publisher, has crafted a book appropriate for the hands to hold and the translations are an achievement of an otherwise difficult writer to translate. Terms are the conditions of a broader text. It is important to note that Serres’ content is as much a thinking of terminal ports. There is a regard for the transportation technology of the written word. For me, this is the mark of genius, a craftiness that tells of a book device that I may trust. Serres is an accomplished thinker and a necessary voice to check the putative trendiness of anti-postmodernist and market-driven theory of endless cultural liquidation. Offering interventions on subjectivity as an open system we are given a chance to affirm the human, not merely to discard it, but to engage its poetic image emotion, the calibratory silent sense of the analogic world; the terms on which we base our efforts. 1 The human is the center of its own negation, constantly mediating it. Something deeper at stake appears in the work then, and it is quite obvious from the onset. Certainly, a book is an intensification of possible text and those who brought this actual book into existence have captured a rarity in regards to the subject matter and artistic accomplishment. I mentioned terms as conditions, so let us understand Biogea as bio-yea, a yes to bios . An affirmation of living and accepting presence for all of its defiance of images, words, and things temporal. Therefore Serres’ existence and its existants plays parts; out of linearity and still like a porous bone pumping blood it manufactures into the fleshy life it becomes. Starting from a man named silence chaos emerges, or the man “Old Taciturn” takes up a journey anticipating a great flood. In other words, a development akin to the one in Genesis. In dealing with this ancestral occupation, fusing Genesis with contemporary philosophical terms, Serres initiates this anachronistic fragmentation under the forming subjectivity of his own autobiography. This mutation in the open system is precisely one of Serres’ terms. There an abyss is at work, stated, but also measured by heels on the ground—the abyss dispatching earthen tensions, that which plays our tunes, that which we abide by and recognize in volcanoes, rivers, oceans, earthquakes and weaponry in the battles of the world. Set in later stages of the book, such tensions are harnessed through scientific principles in an attempt to unify the terms of natural force if only to terminate the world. Thus the elevation of the earth into the world is clearly set forth. Here already, and few pages in, a resonance is set forth under appellations such as the river Garonne, a subjectivity as much as it is inhuman, the river is the inhuman that makes us human. I get the sense that Serres is taking up a challenge issued by Wallace Stevens; namely, that the great poems of heaven and hell have been written, but that only the poem of the earth has resisted composition. 2 On this level we cannot avoid the killing factor of silence, given that our cognition blocks its pure, radical obliteration. Thus a silence of attunement to the earth is in a novel dialectic of the rithmic and rhythm. A technological world, a triumph of termination is set forth. If a text imposes its will given the reader who authorizes it, it is made to convey or convect a presupposition to a reader or its inhabitant(s). Text is therefore both, in-content, contenting, contentedness, and in reading it, a way to navigate self-destruction (dis-content). Here then would one note that the “inhuman” reveals itself, “an aperiodic rhythm of lovers and beloved…the sea as our friend…but as our enemy…maternal vivifying sea.” The sea is an open book, or vaginal birth canal, where the engagement of text comes forth: “…woman sea, open vulva.” One sees like the sea, but only after it, when the uninhabitable truth of inhabiting it switches the polarity of the sailors soul: “I was seeing like the sea” (9-11). In other words, we are invited to embrace the nonsense of the visible. At this point I am taken to Jean-François Lyotard’s work The Inhuman , specifically the first entry on negentropy that would be congruent with Serres’ thematic. 3 The human being exports, deports, or transplants its relation through text, through the system— and this is its sense or relation to silence, to music. Unaware of Serres’ proximity to this work, the concept of gender interrelation as regards a solar catastrophe runs clear. It would be, on this basis, that Serres references his peers, the other texts that, as mentioned above, are discarded in philosophy today. For students of philosophy what we have here is perhaps a gift, a needed project. If silence and death are at work, there is a political valence to deal with, and here, much like the domain of the text and the dominion of the reader, we confront the world of natural, fluid violence. The anti-postmodernist critique is in part based on a weak idea that the loss of ideology, of a world vision, motivates the “correlationist” project. 4 Serres seems to offer another way to view this when he notes that whereas persons “sometimes kill,” it is clearly “the collective” that “always kills” (17). What is the collective today, if not an organizing function we never see yet acts in its favor in the name of truth? One feels a sense of enigma here, if only to link to what Stevens remarked of communism as a “grubby faith,” providing this applies for capitalism as well, namely any ideology of progress overly interested in absolutes. Here we get the sense that the inhuman, silence, this type of killing, always killing, could not be matched by human-made, political dynamos. Or that if it comes to an equilibrium, a catastrophe is never too far from us to read with our heels. We are left to note that the forces of nature presuppose and permeate political systems, the more these systems obtain force, the more the system takes upon itself the proper name of nature that motivates its dissemination, albeit falsely. This note, that in an age of ecocide and technological captivity (sustainability and transparency) political regimes won’t grow our soul-learning ears any larger than our tongues, stands clear to us. The promise of technological desubjectification is here pushed aside. Regarding politics, Serres illustrates this fact: Where did this corpse come from? Who was it? Who killed it? I don’t know. I won’t try to find out. I refuse to get vengeance for it. And I only see Garonne. For our victims, today, are the rivers, too. Their waters have irrigated my life, enchanted my thought, invigorated my body; I’ve known them to be threatening, untamable, as dangerous as the sea when it rages. Yes, murderous. They decided to control their courses; dams, sometimes senseless, destroying sites and valleys, reduced entire populations to servile displacements; programs for the irrigation of thirsty farmland, often beneficial of course, completed their drying up.(22) Serres enters into his idea concerning the captivity of language from the natural into a world system: For thousands of years, we have been licking things with our tongues, covering and daubing them so as to appropriate things for ourselves. If language boils down to a convention, this convention took place between the speakers without consulting the thing named, become as a result the property of those who covered it in this way with their drawn or voiced productions. Malfeasance analyzes these acts of appropriation. Thus every inert object, every living thing as well, sleeps under the covers of signs, a little in the way that, today, a thousand posters shouting messages and ugly riots of color drown, with their filthy flood, the landscapes, or better, exclude them from perception because the meaning, almost nil, of this false language and these base images forms an irresistible source of attraction to our neurons and eyes. This appropriation covers the world’s beauty with ugliness. (38-39) Technological concealment coming to bear, we begin to get a sense of another commentary on the condition of sensing, driving home the necessity of a text dealing with such subject matter to be what its terms insist. Thus toward new openings: The new opening. As low beneath our feet as you like, the Biogea opens us to another space, high enough for us to be able to acquire a wisdom there, that of redeveloping this same place differently from our fathers, this place that’s still politically cut up by old hatreds, beneath the flood of tears and blood that we call history. Without this soft place, spiritually very old, but newly conceived in this way, without the juridical construction of a common good, opposed to our filthy ownership, I don’t see how our planet, hard, will survive. Hardness that depends on a softness, material belonging that depends on this temporary rented location (51). Serres enters into a summit on the content and the structure of his work. Archimedes is brought in with the concept of three volcanoes. Meaning fire, but as well earth, water, air. For it was Archimedes’ war machines that sought to lift the earth, thus bringing in the question of principles of science: “can a principle be invented while controlling its consequences?” (66-7). May the earth be put in a sentence, terminated by terminology, appellations, gone wild? By means of these element-dominating laws, this old physicist began to tear nature away from the ancient myths; by a strange return, today we’re plunging our successes back into the anxieties and terrors from which that ancient physics was born. Yes, our new history of science and technology is plunging, today, as though in a loop, into the fundamental human myths from which Empedocles’ first laws came. A major progression and a regression on the nether side of the origins. Consequently, the contemporary time requires that we try to return to that unity in which the principles of hate and love are at the same time human, living, inert and global. We will never attain a deontology of our knowledge and actions without thinking the subjective, the objective, the collective, and the cognitive all together simultaneously. Here, hate and love are the result of these four components.(71) Working then on the concept of fire-starting mirrors to the atomic annihilation of the Second War, Serres works into the subjectivity in question on the matter of rhythm—say rithmic— precisely at that point: Knowledge is changing today. The all-political is dying; the monarchy of the sciences said to be hard is coming to a close. The science of the things of the world will have to communicate just as much as the things of the world do, which do it much better than humans do, who don’t always want to do it. Let’s celebrate two changes this morning. The first one strikes a new blow to our narcissism. No, knowledge and the world don’t resemble our analytical enjoyments of refined cutting up, of endless debates and of exclusions full of hate. They, on the contrary, form a bloc and a sum, alliance and alloys. Uniting the fields of knowledge among themselves the way the things are connected among themselves, the second newness puts into place sets united by interlacing, webs and simplexes that combine with the things of the world, themselves combined, the combined knowledge that understands them.(130-1) Biogea closes on its opening flood thematic, approaching the initial telos of Genesis. Here the trees are brought into a position with atmosphere, the opaque abyssal reservoir, the tomb of the sun, sea in the polarity of the earthen heaven and hell. The poem of the earth then is silent but deadly, indeed, as funny as that phrase is, mainly a tomb gas. The meaning of the living and the non-meaning of things converge in the muteness of the world; this meaning and non-meaning plunge there and come out, the ultimate eddy. Mundus patet: through a fissure, through an opening, a fault, a cleft come noises, calls as small as these apertures. I’m listening, attentive, I’m translating, I’m advancing in the scaled-down meaning and science. Mundus patet: should the world open greatly, it will launch me into its silence. The totality remains silent. Knowledge expanded in elation. White origin of meaning, fountain of joy. (198) Final Remarks One test of a review is the long term trajectory the referee thinks the book will have. I see Serres’ text lending greatly into the vision of Biogea . In fact, in the vision of the novel inquiries of Stephen Jay Gould’s work there is something to be thought on the level of the individual and the species; namely, that humanity and its uniqueness is in its deferral, its thinking and naming, a thinking surrounded by silence that filters into everything, that pulls us through the world, the kinetic pulse we recognize, and all of that we cleave away in the base philosophical maxim of difference itself. Unique individuals are spatial creatures: we dwell, and we ought to get good at it. Yet this is an imaginative space that, if you are crazy enough to believe it, de-term-ine the conditions of its own terms. That is why we are not merely creating spaces on the acceleration of time, or so this ignoramus thinks, to accidentally transcend. Imagination already has this insatiable silence that we drink up and fail to manifest. Space is timeless. The imagination itself, shared by humans for themselves, their objects, and the species as a whole, is a non-defined space of relation; a whole human trajectory as part of nature, and part of worlds that are the other side of thinking nature, the consequence of it, at least our attempt to do so. Our survival is based on our deliberation, our caution, our natural deconstructive sense toward this silence that is already part of the song, sung, singing of this century without end. Good books will let us inhabit this space and recognize a form of life. Serres’ text moves toward dwelling, as noted, in masterful and accessible ways. The pitched battles are the falling replays of anemic and dead politics. As soon as we realize there is humanity, we may be able to enjoy the end of it, our inhuman capability of listening to silence. NOTES 1. See Michel Serres. The Parasite .

This chapter introduces a distinctive approach for scientific metaphysics. Instead of drawing metaphysical conclusions by interpreting the most basic theories of science, this approach draws metaphysical conclusions by analyzing how multifaceted practices of science work. Broadening attention opens the door to drawing metaphysical conclusions from a wide range of sciences. This chapter analyzes conceptual practice in genetics to argue that the reality investigated by biologists lacks an overall structure. It expands this conclusion to motivate the no general structure thesis, which (...) states that the world lacks a general, overall structure that spans scales. It concludes that the no general structure thesis counts as metaphysics because it says something very important and general about the world. This thesis informs science as well as philosophy of science, and it provides a useful perspective for societies that look upon science to help solve complex problems in our changing world. (shrink)

Although historians have carefully examined exactly what role the analogy between artificial and natural selection might have played in Charles Darwin's discovery of natural selection, philosophers have not devoted much attention to the way Darwin employed the analogy to justify his theory. I suggest that philosophers tend to belittle the role that analogies play in the justification of scientific theories because they don't understand the special nature of analogical inference. I present a novel account of analogical argument developed by Julian (...) Weitzenfeld and then use it to carry out an in-depth analysis of Darwin's argument from artificial selection. (shrink)

Waters, Ian One of the most universally acclaimed films of 2014 was Calvary, a parable of the betrayal of the Irish people by the Irish Catholic Church. The context for the film was the Irish Catholic Church, which had previously defined Ireland's soul, and had recently been revealed to have consciously and methodically covered up atrocities perpetrated in church institutions.

Waters, Ian; McGuckin, Robert The following document has been produced to assist priests and deacons of the Latin Catholic Church in their parish pastoral ministry. It does not attempt to be a scholarly or technical treatment. Often, as regards questions about marriage, a canonist will need to be consulted.

Waters, Ian The Australian hierarchy was established by Pope Gregory XVI in 1842. Since then, there have been six national Catholic councils held in Australia. The first two, celebrated in 1844 and 1869, are known as the First Provincial Council of Australia and the Second Provincial Council of Australia, as until 1874 the Australian dioceses were all in the one ecclesiastical province with Sydney being the sole metropolitan see. In 1874, a second province - Melbourne - was established, and the (...) national councils since then - four of them, celebrated in 1885, 1895, 1905 and 1937 - have been called plenary councils, the term used in the Catholic Church in recent centuries for councils whose participants are from more than one ecclesiastical province; in the past, terms such as regional councils or national councils have been used. As we all know, another plenary council for Australia is planned to commence in 2020. (shrink)

Traditional approaches in philosophy of biology focus attention on biological concepts, explanations, and theories, on evidential support and inter-theoretical relations. Newer approaches shift attention from concepts to conceptual practices, from theories to practices of theorizing, and from theoretical reduction to reductive retooling. In this article, I describe the shift from theory-focused to practice-centered philosophy of science and explain how it is leading philosophers to abandon fundamentalist assumptions associated with traditional approaches in philosophy of science and to embrace scientific pluralism. This (...) article comes in three parts, each illustrating the shift from theory-focused to practice-centered epistemology. The first illustration shows how shifting philosophical attention to conceptual practice reveals how molecular biologists succeed in identifying coherent causal strands within systems of bewildering complexity. The second illustration suggests that analyzing how a multiplicity of alternative models function in practice provides an illuminating approach for understanding the nature of theoretical knowledge in evolutionary biology. The third illustration demonstrates how framing reductionism in terms of the reductive retooling of practice offers an informative perspective for understanding why putting DNA at the center of biological research has been incredibly productive throughout much of biology. Each illustration begins by describing how traditional theory-focused philosophical approaches are laden with fundamentalist assumptions and then proceeds to show that shifting attention to practice undermines these assumptions and motivates a philosophy of scientific pluralism.

In this paper, Waters introduces American Indians who hold a Ph.D. in philosophy. Waters explains that because American Indians are unable to garner the financial, collegial, and academic support needed to rise to inclusive positions in the philosophical profession, most of our colleagues and students remain uneducated and ignorant about indigenous people and our philosophies that are still alive today on this shared American continent. America’s indigenous philosophers have important contributions to make to philosophy and culture; yet our conceptual nonexistence (...) exacerbates our veridical non- integration. It is a cultural luxury for the APA to not address these problems. In some moral worlds, the APA Board might have a positive obligation to address the status of American Indian philosophy with all due haste. Three possible ways of indexing American Indian philosophy for inclusion in the discipline are presented, each raising unique and particular problems for the profession. It is suggested a field of Indigenous philosophy (global) could emerge over time, having subfields of diverse cultural philosophies, not necessarily linked to nation states or current geopolitical regions. Concluding, given issues of invisibility, alliances, and responsibility, the APA remains historically morally bound to address and perhaps even redress American Indian exclusionism in the profession upon which it acts, and in the culture it complicitly creates.

This syllabus engages dialogue about indigenous philosophical ideas and issues that frame contemporary global indigenous thought, perspective, and worldview. We explore how presuppositions of indigenous philosophy, including epistemology (how/what we know), metaphysics (what is), science (stories), and ethics (practices), affect global research programs, intellectual cultural property, economic policies, ecology, biodiversity, taxonomy, health, housing, food, employment, economic sustainability, peace negotiations, climate justice, human/treaty rights, colonial law, refugees and incarceration, self-determination, sovereignty, nation building, and digital information. Readings provide an understanding of traditional (...) and contemporary indigenous philosophical frameworks of interpretation, developments of the 1994-2004 United Nations Decade of Indigenous Peoples, the UN Permanent Forum of Indigenous Peoples, and the recent Indigenous Conference in Cancun (philosophical importance of the World Trade Organization [WTO], the World Bank [WB], the International Monetary Fund [IMF], and NAFTA).

We are living in an emerging technoculture. Machines and gadgets not only weave the fabric of daily life, but more importantly embody philosophical and religious values which shape the contemporary moral vision - a vision that is often at odds with Christian convictions. This book critically examines those values, and offers a framework for how Christian moral theology should be formed and lived-out within the emerging technocuilture. Brent Waters argues that technology represents the principal cultural background against which contemporary Christian (...) moral theology is formed. (shrink)

What should philosophers of science accomplish when they analyze scientific concepts and interpret scientific knowledge? What is concept analysis if it is not a description of the way scientists actually think? I investigate these questions by using Hans Reichenbach's account of the descriptive, critical, and advisory tasks of philosophy of science to examine Karola Stotz and Paul Griffiths' idea that poll-based methodologies can test philosophical analyses of scientific concepts. Using Reichenbach's account as a point of departure, I argue that philosophy (...) of science should identify and clarify epistemic virtues and describe scientific knowledge in relation to these virtues. The role of concept analysis is to articulate scientific concepts in ways that help reveal epistemic virtues and limitations of particular sciences. This means an analysis of the gene concept should help clarify the explanatory power and limitations of gene-based explanations, and should help account for the investigative utility and biases of gene-centered sciences. I argue that a philosophical analysis of gene concept that helps achieve these critical aims should not be rejected on the basis of poll-based studies even if such studies could show that professional biologists don't actually use gene terminology in precise ways corresponding to the philosophical analysis.

Darwinians are realists about the force of selection, but there has been surprisingly little discussion about what form this realism should take. Arguments about the units of selection in general and genic selectionism in particular reveal two realist assumptions: (1) for any selection process, there is a uniquely correct identification of the operative selective forces and the level at which each impinges; and (2) selective forces must satisfy the Pareto-style requirement of probabilistic causation. I argue that both assumptions are false; (...) we must temper realism about the force of selection and revise the way we think about probabilistic causation. (shrink)

Philosophers’ traditional emphasis on theories, theoretical modeling, and explanation misguides research in philosophy of science. Articulating and applying core theories is part of scientific practice, but it is not the essence of scientific practice. Insofar as science has an essence, it is to systematically investigate and learn about what is not yet understood. This lecture analyzes genetics to articulate a broad-practice-centered approach to philosophy of science. It concludes by arguing that this approach can lead to richer, deeper, and more useful (...) philosophies of science, philosophies that can better inform science policy and the public’s understanding of science.

I present an account of classical genetics to challenge theory-biased approaches in the philosophy of science. Philosophers typically assume that scientific knowledge is ultimately structured by explanatory reasoning and that research programs in well-established sciences are organized around efforts to fill out a central theory and extend its explanatory range. In the case of classical genetics, philosophers assume that the knowledge was structured by T. H. Morgan’s theory of transmission and that research throughout the later 1920s, 30s, and 40s was (...) organized around efforts to further validate, develop, and extend this theory. I show that classical genetics was structured by an integration of explanatory reasoning and investigative strategies . The investigative strategies, which have been overlooked in historical and philosophical accounts, were as important as the so-called laws of Mendelian genetics. By the later 1920s, geneticists of the Morgan school were no longer organizing research around the goal of explaining inheritance patterns; rather, they were using genetics to investigate a range of biological phenomena that extended well beyond the explanatory domain of transmission theories. Theory-biased approaches in history and philosophy of science fail to reveal the overall structure of scientific knowledge and obscure the way it functions.Author Keywords: Investigation; Genetic approach; Structure of knowledge; Classical genetics.

Former discussions of biological generalizations have focused on the question of whether there are universal laws of biology. These discussions typically analyzed generalizations out of their investigative and explanatory contexts and concluded that whatever biological generalizations are, they are not universal laws. The aim of this paper is to explain what biological generalizations are by shifting attention towards the contexts in which they are drawn. I argue that within the context of any particular biological explanation or investigation, biologists employ two (...) types of generations. One type identifies causal regularities exhibited by particular kinds of biological entities. The other type identifies how these entities are distributed in the biological world. (shrink)
