When dealing with biological communication and information, unifying concepts are necessary in order to couple the different “codes” that are being inductively “cracked” and defined at different emergent and “deemergent” levels of the biological hierarchy. In this paper I compare the type of biological information implied by genetic information with that implied in the concept of “quorum sensing” (which refers to a prokaryotic cell-to-cell communication system) in order to explore if such integration is being achieved. I use the (...) Lux operon paradigm and the Vibrio fischeri – Euprymna scolopes symbiotic partnership to exemplify the emergence of informational contexts along the biological hierarchy (from molecules to ecologies). I suggest that the biosemiotic epistemological framework can play an integrative role to overcome the limits of dyadic mechanistic descriptions when relating the different emergent levels. I also emphasise that the realisation ofbiology as being a “science of sensing” and the new importance that is being ascribed to the “context” in experimental biology corroborate past claims ofbiosemioticians about a shift from a focus on information (as a material agent of causality) towards a focus on the world of signification.

The importance of electrical signalling in bacteria is an emerging paradigm. Bacillus subtilis biofilms exhibit electrical communication that regulates metabolic activity and biofilm growth. Starving cells initiate oscillatory extracellular potassium signals that help even the distribution of nutrients within the biofilm and thus help regulate biofilm development. Quorum sensing also regulates biofilm growth and crucially there is convergence between electrical and quorum sensing signalling axes. This makes B. subtilis an interesting model for cell signalling research. SpoOF (...) is predicted to act as a logic gate for signalling pathway convergence, raising interesting questions about the functional nature of this gate and the relative importance of these disparate signals on biofilm behaviour. How is an oscillating signal integrated with a quorum signal? The model presented offers rich opportunities for future experimental and theoretical modelling research. The importance of direct cell‐to‐cell electrical signalling in prokaryotes, so characteristic of multicellular eukaryotes, is also discussed. (shrink)

Communication is defined as an interaction between at least two living agents which share a repertoire of signs. These are combined according to syntactic, semantic and context dependent, pragmatic rules in order to coordinate behavior. This volume deals with the important roles of soil bacteria in parasitic and symbiotic interactions with viruses, plants, animals and fungi. Starting with a general overview of the key levels of communication between bacteria, further reviews examine the various aspects of intracellular as well as intercellular (...) biocommunication between soil microorganisms. Th is includes the various levels of biocommunication between phages and bacteria, between soil algae and bacteria, and between bacteria, fungi and plants in the rhizosphere, the role of plasmids and transposons, horizontal gene transfer, quorum sensing and quorum quenching, bacterial-host cohabitation, phage-mediated genetic exchange and soil viral ecology.

In this article, I demonstrate two ways in which our major theories of the evolution of cooperation may fail to capture particular social phenomena. The first shortcoming of our current major theories stems from the possibility of mischaracterizing the cooperative problem in game theory. The second shortcoming of our current major theories is the insensitivity of these explanatory models to ecological and genomic context. As a case study to illustrate these points, I will use the cooperative interaction of a species (...) of myxobacteria called Myxococcus xanthus. M. xanthus cooperate in many areas of their life cycle—in quorum sensing, social motility, fruiting body formation, and predation. I focus in particular on predation as we have not yet discovered an adequate explanation of how they sustain cooperative predation in the face of developmental cheats. In explaining why we have not, I draw generalizable conclusions that shed light on our use of simplified models to explain real-world behaviors in a variety of organisms. (shrink)

Individual bacterial cells can communicate via quorum sensing, cooperate to harvest nutrients from their environment, form multicellular biofilms, compete over resources and even kill one another. When the environment that bacteria inhabit is an animal host, these social behaviours mediate virulence. Over the last decade, much attention has focussed on the ecology, evolution and pathology of bacterial cooperation, and the possibility that it could be exploited or destabilised to treat infections. But how far can we really extrapolate from (...) theoretical predictions and laboratory experiments to make inferences about ‘cooperative’ behaviours in hosts and reservoirs? To determine the likely importance and evolution of cooperation ‘in the wild’, several questions must be addressed. A recent paper that reports the dynamics of bacterial cooperation and virulence in a field experiment provides an excellent nucleus for bringing together key empirical and theoretical results which help us to frame – if not completely to answer – these questions.

The sociobiology of bacteria, largely unappreciated and ignored by the microbiology research community two decades ago is now a major research area, catalyzed to a significant degree by studies of communication and cooperative behavior among the myxobacteria and in quorum sensing (QS) and biofilm formation by pseudomonads and other microbes. Recently, the topic of multicellular cooperative behaviors among bacteria has been increasingly considered in the context of evolutionary biology. Here we discuss the significance of two recent studies1,2 of (...) the phenomenon of “cheating” mutants and their exploitation of cooperating microbial populations of Pseudomonas aeruginosa.

Cybernetic Bacteria is an ongoing transdisciplinary investigation that brings together art, philosophy, microbiology and digital technology to examine the relationship of the emerging science of bacterial communication to our own digital communications networks, looking in particular at ‘packet data’ and bacterial quorum sensing. The project seeks to compare philosophical notions of the sublime with a kind of bacterial sublime, demonstrating the greater complexity of the interactions taking place at a microscopic level, when compared to human communication technologies such (...) as the World Wide Web (with particular focus on scale-free networks). The first artwork in the series employed a clear plastic tube of liquid agar jelly planted into earth to allow the soil bacteria beneath to grow upwards and become visible. A total of 100 µL of Homoserine Lactone, a hormone used by bacteria for quorum sensing (a form of bacterial communication), was then added by the artist as part of a performance lecture, with her in effect saying: ‘I’m here’ to the bacteria below. The microbes that have been communicated to then pass the signal on to their neighbours and so on. In theory this enables the signal to travel around the planet. However, the main issue with this work is one of Hermeneutics; the bacteria, which receive the communication, will not identify the artist as human – simply as another (albeit very large) bacterium. The project has subsequently evolved into a multiple screen digital artwork showing network traffic taking place in real time (web traffic, RFID and Bluetooth), a film of bacterial communication in progress (using two strains of genetically modified bacteria) and an interactive conceptualisation of the data from both sources generated using artificial life. The project continues. (shrink)

Philosophers of biology, along with everyone else, generally perceive life to fall into two broad categories, the microbes and macrobes, and then pay most of their attention to the latter. ‘Macrobe’ is the word we propose for larger life forms, and we use it as part of an argument for microbial equality. We suggest that taking more notice of microbes – the dominant life form on the planet, both now and throughout evolutionary history – will transform some of the philosophy (...) of biology’s standard ideas on ontology, evolution, taxonomy and biodiversity. We set out a number of recent developments in microbiology – including biofilm formation, chemotaxis, quorum sensing and gene transfer – that highlight microbial capacities for cooperation and communication and break down conventional thinking that microbes are solely or primarily single-celled organisms. These insights also bring new perspectives to the levels of selection debate, as well as to discussions of the evolution and nature of multicellularity, and to neo-Darwinian understandings of evolutionary mechanisms. We show how these revisions lead to further complications for microbial classification and the philosophies of systematics and biodiversity. Incorporating microbial insights into the philosophy of biology will challenge many of its assumptions, but also give greater scope and depth to its investigations. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Volcanus: Recherches comparatistes sur les origines du culte de VulcainJ. LinderskiGérard Capdeville. Volcanus: Recherches comparatistes sur les origines du culte de Vulcain. Rome: Ecole Française de Rome, Palais Farnèse, 1995. viii 1 521 pp. Cloth, no price stated. (Bibliothèque des Ecoles Françaises d’Athènes et de Rome, fasc. 288)In the last twenty years the French School has published every two years one book on Roman religion: monographs dealing with (...) Fortuna, Mercurius, Ops, Penates, Providentia Deorum, Fratres Arvales, l’Association Dionysiaque (cf. JRS 78 [1988] 207–8), the Bacchanalia, religious architecture (Aurea templa), La vie religieuse des matrones, Le délit religieux (cf. CP 79 [1984] 174–77). Now we have a book about Volcanus. First let us remark on what this book is not: it is not a study of the cult of Volcanus, an encyclopedia that would systematically list and discuss all the literary, iconographic, and epigraphical evidence in Rome, Italy, and the provinces. It would be very pleasing to have such a book; perhaps pedestrian, but useful. For information we still have to turn to Georg Wissowa, to his ageless Religion und Kultus der Römer (2d ed. Munich 1912, 229–32); also informative is W. Eisenhut, “Volcanus,” RE Suppl. 14 (1974) 948–62. A rather balanced account of the origines appears in G. Camassa, “Sull’origine [End Page 644] e le funzioni del culto di Volcanus a Roma,” RSI 96 (1984) 811–54. Capdeville’s book we have for speculations, a paradise for those eager to delve into murky origins, and those who are transposed by the dazzling and uncertain art of comparativistic pleading. If bibliography (fifty-one pages, 425–75) stands for learning, it is a learned monograph; it ranges from Rome through Etruria to Crete and Cyprus. Surprisingly we find no Hittites or Turks (the relevance of the latter the reader will see revealed at the end of this piece).The book opens with an evocation of Georges Dumézil. Where do his manes lead the author? They lead to the fish. The monograph “est né... d’une interrogation sur les pisciculi des Volcanalia” (1), a subject which intrigued Dumézil himself (REL 36 [1959] 121–30). At the feast of Volcanalia on 23 August (see the references in A. Degrassi, Fasti anni Numani et Iuliani (5 Inscr. It. XIII.2 [Rome 1963] 500–502), populus pro se in ignem animalia mittit (Varr. LL 6.20). On 7 June (cf. Degrassi 466) the Ludi Piscatorii were celebrated a praetore urbano pro piscatoribus Tiberinis, quorum quaestus non in macellum pervenit, sed fere in aream Volkani, quod id genus pisciculorum vivorum datur ei deo pro animis humanis (Festus 274–76 L); but at the Ludi Piscatorii the offering was not pro animis but rather pro quaestu piscantium (Festus 232 L); cf. J. Le Gall, Recherches sur le culte du Tibre (Paris 1953) 48–50; J. Linderski, Ktema 17 ([1992] 1996) 58. Agni, the Indian god of fire, hated water and fish; this explains the Roman ritual (so Dumézil). Most scholars tacitly assume that pisciculi vivi were offered also on the Volcanalia, but Varro speaks generally of animalia: if he wanted to say pisces he would have said so. Volcanus was a god of destructive fire (so Wissowa, Dumézil, and many other scholars); it makes sense that to propitiate him not only fish, a symbol of water, were burnt, but also other animals (perhaps as a substitute offering; cf., on that sort of sacrifices, G. Capdeville, MEFRA 83 [1971] 283–323). In the context of incendia arcenda an inscription of the Domitianic time (ILS 4914) records an offering on the Volcanalia of vitulus robeus and verres r(obeus). This calls to mind the sacrifice of the rutilae canes to protect the crops from the burning sun (Festus 358 L).Of all of this Capdeville, surprisingly, does not write at all: after their debut on page 1 the pisciculi and the Volcanalia feebly reappear at the very end of the book (420–23), only to be disregarded. Capdeville claims that Volcanus was not at all, and never, a god of “feu destructeur.” But Dumézil too... (shrink)

One of the goals of computerized tutoring systems is to optimize the learning of facts. Over a hundred years of declarative memory research have identified two robust effects that can improve such systems: the spacing and the testing effect. By making optimal use of both and adjusting the system to the individual learner using cognitive models based on declarative memory theories, such systems consistently outperform traditional methods (Van Rijn, Van Maanen, & Van Woudenberg, 2009). This adjustment process is driven by (...) a continuously updated estimate of the rate of forgetting for each item and learner on the basis of the learner's accuracy and response time. In this study, we investigated to what extent these estimates of individual rates of forgetting are stable over time and across different materials. We demonstrate that they are stable over time but not across materials. Even though most theories of human declarative memory assume a single underlying rate of forgetting, we show that, in practice, it makes sense to assume different materials are forgotten at different rates. If a computerized, adaptive fact‐learning system allowed different rates of forgetting for different materials, it could adapt to individual learners more readily. (shrink)

Large changes in a scene often become difficult to notice if made during an eye movement, image flicker, movie cut, or other such disturbance. It is argued here that this _change blindness_ can serve as a useful tool to explore various aspects of vision. This argument centers around the proposal that focused attention is needed for the explicit perception of change. Given this, the study of change perception can provide a useful way to determine the nature of visual attention, and (...) to cast new light on the way that it is?and is not?involved in visual perception. To illustrate the power of this approach, this paper surveys its use in exploring three different aspects of vision. The first concerns the general nature of _seeing_. To explain why change blindness can be easily induced in experiments but apparently not in everyday life, it is proposed that perception involves a _virtual representation_, where object representations do not accumulate, but are formed as needed. An architecture containing both attentional and nonattentional streams is proposed as a way to implement this scheme. The second aspect concerns the ability of observers to detect change even when they have no visual experience of it. This _sensing_ is found to take on at least two forms: detection without visual experience (but still with conscious awareness), and detection without any awareness at all. It is proposed that these are both due to the operation of a nonattentional visual stream. The final aspect considered is the nature of visual attention itself?the mechanisms involved when _scrutinizing_ items. Experiments using controlled stimuli show the existence of various limits on visual search for change. It is shown that these limits provide a powerful means to map out the attentional mechanisms involved. (shrink)

It has often been assumed that when we use vision to become aware of an object or event in our surroundings, this must be accompanied by a corresponding visual experience (i.e., seeing). The studies reported here show that this assumption is incorrect. When observers view a sequence of displays alternating between an image of a scene and the same image changed in some way, they often feel (or sense) the change even though they have no visual experience of it. The (...) subjective difference between sensing and seeing is mirrored in several behavioral differences, suggesting that these are two distinct modes of conscious visual perception. (shrink)

The fields of machine learning (ML) and cognitive science have developed complementary approaches to computationally modeling human behavior. ML's primary concern is maximizing prediction accuracy; cognitive science's primary concern is explaining the underlying mechanisms. Cross-talk between these disciplines is limited, likely because the tasks and goals usually differ. The domain of e-learning and knowledge acquisition constitutes a fruitful intersection for the two fields’ methodologies to be integrated because accurately tracking learning and forgetting over time and predicting future performance based on (...) learning histories are central to developing effective, personalized learning tools. Here, we show how a state-of-the-art ML model can be enhanced by incorporating insights from a cognitive model of human memory. This was done by exploiting the predictive performance equation's (PPE) narrow but highly specialized domain knowledge with regard to the temporal dynamics of learning and forgetting. Specifically, the PPE was used to engineer timing-related input features for a gradient-boosted decision trees (GBDT) model. The resulting PPE-enhanced GBDT outperformed the default GBDT, especially under conditions in which limited data were available for training. Results suggest that integrating cognitive and ML models could be particularly productive if the available data are too high-dimensional to be explained by a cognitive model but not sufficiently large to effectively train a modern ML algorithm. Here, the cognitive model's insights pertaining to only one aspect of the data were enough to jump-start the ML model's ability to make predictions—a finding that holds promise for future explorations.

It remains a standing problem how and why the first nervous systems evolved. Molecular and genomic information is now rapidly accumulating but the macroscopic organization and functioning of early nervous systems remains unclear. To explore potential evolutionary options, a coordination centered view is discussed that diverges from a standard input–output view on early nervous systems. The scenario involved, the skin brain thesis, stresses the need to coordinate muscle-based motility at a very early stage. This paper addresses how this scenario with (...) its focus on coordination also deals with sensory aspects. It will be argued that the neural structure required to coordinate extensive sheets of contractile tissue for motility provides the starting point for a new multicellular organized form of sensing. Moving a body by muscle contraction provides the basis for a multicellular organization that is sensitive to external surface structure at the scale of the animal body. Instead of thinking about early nervous systems as being connected to the environment merely through input and output, the implication developed here is that early nervous systems provide the foundation for a highly specific animal sensorimotor organization in which neural activity directly reflects bodily and environmental spatiotemporal structure. While the SBT diverges from the input–output view, it is closely linked to and supported by ongoing work on embodied approaches to intelligence to which it adds a new interpretation of animal embodiment and sensorimotor organization.

This essay is an examination of how sensing capacities can draw in, and from, other-than-human entities—both animate and inanimate. Based upon ethnographic field research in Iceland, it describes sensory encounters that are realizable through the bodies, sensations, and ontological status shifts of other beings and entities, namely, in bears and ice and earth. As anthropogenic impacts deepen, the essay argues, sensing ought to be practiced as a collaborative effort among human and other-than-human entities. Sensing by other means (...) entails sensing through others’ means and beyond the human sensorium. (shrink)

After introducing the concept of compressed sensing as a complementary measurement mode to the classical Shannon-Nyquist approach, I discuss some of the drivers, potential challenges and obstacles to its implementation.

In the late nineteenth century, Jagadish Chandra Bose devised millimeter- and micro-wave experiments to record responses of plants to electromagnetic stimuli. Based on these experiments, Bose conceptualized his thesis of the unity of living and nonliving entities through their different sensitivities to electromagnetic vibrations. By relating Bose’s thesis of the unity of life based on electromagnetic vibrations to Alfred North Whitehead’s process philosophy and N. Katherine Hayles’s work on the cognitive nonconscious, I argue for a processual media theory that connects (...) both human and plant intelligence to electromagnetic signaling. In doing so, I examine how discourses about different living bodies (plants, animals, humans) variously sensing their environments are formulated into claims about which species have what degree of cognitive capability and intelligence. I trace the influence of Bose’s work on the ecological thinking of the 1970s espoused by cyberneticists and countercultural environmentalists and on contemporary plant neurobiologists who are closely working with Internet of Things designers and researchers. This enables me to emerge with an understanding of electrosensitivity that acknowledges that there is more to the intensities and energies of signals than mere data and that such infra-informatic signals can create both capacities and incapacities, capabilities and debilities, in bodies.

The case studies presented here involve four objects from the collection of the Hunterian (...) Museum as sensed and interpreted by scholars of psychology, philosophy, sociology, and anthropology.

Using the exemplary case of 19th-century American state penitentiaries, the authors explore penitentiary control from the perspective of sensing agents who navigate a controlled sensory ecology – the prison, as structured by institutional rules, differential power relations, and architectural plans.

Employing wardens’ disciplinary journals and other secondary reports, the article emphasizes three theoretical issues that (...) explain why Panoptical prisons’ attempts to control sense experiences can sometimes fail: architectural designs that inadequately negotiate the contradictory demands of visual and acoustic control; inmates’ active mobilization of perceptible objects as means of resistance; and power differences between prison authorities and inmates that prevent actors from sharing a common sensory field. The authors’ overarching goal is to advance, via pragmatism, a sensory analysis of institutional control. (shrink)

Merleau-Ponty advances a notion of witness in The Visible and the Invisible, which could be termed “gestate.” Gestate witness involves an acknowledgement through one's own body of how another living entity is born into its own body. This notion of witness is helpful in answering Anthony Weston's challenge that a sufficiently positive notion of environmentalism and so of environmental responsibility be developed, one that takes seriously how we come into contact with a more-than-human animate world. The work of biologist Tarn (...) Ream with Trillium ovatum serves as a case study in the aesthetic, ethical and ontological significance of gestate witness. (shrink)

This is an explorative work on teaching. The understanding of teaching that I use in my work is that teaching is action, it happens in the present – here and now. So, while teaching refers to shorter timespans, education in this understanding refers to timespans that are of a longer duration, meaning education is communication between generations. The notion of teaching I explore draw from experiences, for my own part between nature, dog and human. These are experiences of sensing (...) where one flows through and interconnects with others, so that boundaries are difficult to discern, and hence boundaries are not the point, but rather how sensing bodies and ‘movements between’ create experiences that are constitutive of who we become both as dog and human, in/with nature. Here I am not referring this to learning, as is usual in the equation “teaching and learning”. This does not mean learning is irrelevant, but rather that it is such an encompassing concept I cannot deal with it satisfactorily in this article. Also, I go beyond what is commonly understood as learning, in terms of making a change in someone’s cognitive or emotional structures. This article explores the kind of experiences our sensing body furnish us with and how these transfer to memory, in the here and now bodies sense, and how this creates memories. I argue this is especially important to recognize in teaching, but seldom addressed. I suggest we pay more attention to these experiences of sensing and how it becomes part of individual and collective memories. To me this is a vital and integral part in all teaching, in the present.

Instead of presuming the ‘observer’ as given, we are (re)sensing the observer and are thereby offering an ‘open order cybernetics’ (OOC). We are first of all concerned about our acquisition and use of language as the precondition for any meaningful statement. This self-reflexive point of departure distinguishes our project from philosophers who are presuming ‘something’ (‘closure’, ‘selforganization’, ‘self ’, ‘auto-poiesis’, ‘senses’, ‘objects’, ‘subjects’, ‘language’, ‘nervous systems’ etc.) in the first place without being aware of their presumptions i.e. that they (...) are able to already talk meaningfully about ‘something’. We are undertaking a self-reflexive loop towards our already undertaken ‘meaningful’ actions, reflecting inside our concepts on our concepts, trying to find out how our concepts about ‘something’ have come into existence. We are reflecting on our concepts through this ongoing open investigation. We are sketching the ramifications of such a self-reflexive loop for epistemology as well as for the main research areas within cognitive science (i.e. language acquisition, perception, consciousness). We are also pointing towards virtual reality in combination with the arts as an awareness aid, helping us in our self-reflexive endeavours. (shrink)

River segmentation of remote sensing images is of important research significance and application value for environmental monitoring, disaster warning, and agricultural planning in an area. In this study, we propose a river segmentation model in remote sensing images based on composite attention network to solve the problems of abundant river details in images and the interference of non-river information including bridges, shadows, and roads. To improve the segmentation efficiency, a composite attention mechanism is firstly introduced in the central (...) region of the network to obtain the global feature dependence of river information. Next, in this study, we dynamically combine binary cross-entropy loss that is designed for pixel-wise segmentation and the Dice coefficient loss that measures the similarity of two segmentation objects into a weighted one to optimize the training process of the proposed segmentation network. The experimental results show that compared with other semantic segmentation networks, the evaluation indexes of the proposed method are higher than those of others, and the river segmentation effect of CoANet model is significantly improved. This method can segment rivers in remote sensing images more accurately and coherently, which can meet the needs of subsequent research. (shrink)

Reflectance spectroscopy is a standard tool for studying the mineral composition of rock and soil samples and for remote sensing of terrestrial and extraterrestrial surfaces.

We compare the reliability of the procedure to (...) the reliability of several other automated methods adapted to the same purpose. Evidence is given that the procedure can be applied to some other mineral classes as well.

It will be argued that in order to overcome the main difficulty of these theories the senses should be interpreted as physical detectors. A new theory, Grounded Functionalism, will be proposed, which retains multiple (...) realizability while allowing for a scientifically based approach toward accounting for qualia in the natural world.

In this paper, we discuss the weakness of current action languages for sensing actions with respect to modeling domains with multi-valued fluents. To address this problem, we propose a language with sensing actions and multi-valued fluents, called AMK, provide a transition function based semantics for the language, and demonstrate its use through several examples from the literature. We then define the entailment relationship between action theories and queries in AMK, denoted by ⊧AMK, and discuss some properties about AMK.

In this modern world, a massive amount of data is processed and broadcasted daily. This includes the use of high energy, massive use of memory space, and increased power use. In a few applications, for example, image processing, signal processing, and possession of data signals, etc., the signals included can be viewed as light in a few spaces. The compressive sensing theory could be an appropriate contender to manage these limitations. “Compressive Sensing theory” preserves extremely helpful while signals (...) are sparse or compressible. It very well may be utilized to recoup light or compressive signals with less estimation than customary strategies. Two issues must be addressed by CS: plan of the estimation framework and advancement of a proficient sparse recovery calculation.

The exhibition of acquisition and reconstruction strategies is examined regarding the Compression Ratio, Reconstruction Accuracy, Mean Square Error, and so on. (shrink)

This editorial examines how sensing practices are transforming through proliferating sensor technologies and altered sensing relations. Rather than engage with sensing as a project of the human mind or body as usually delineated within sensory classifications, this overview of sensors and sensing practices documents how sensing entities are emerging that are composed of shifting ensembles of multiple humans and more-than-humans, environments and technologies, politics and practices. By decoupling sensing from its exclusive human orientation, the (...) editorial and collection demonstrate how reworked approaches to sensing make it possible to tune in to how involvement with environmental problems unfolds and endures. The collection asks how sensing practices might be crafted that attend to the distributed and accumulative inequalities of environmental problems and to speculate toward differential collectives for addressing environmental crisis and change.

Outlining the onto-epistemological implications of being ‘in touch with’ sensor-media, the contribution raises questions of what it means to be included in an infrastructure of sensorial interfaces - not only of tech-assisted human-to-human or human-to-machine communication, but of unmanageable processes of machine-to-machine exchange. Delineating sensors as media necessitates reflections on the temporal relations (...) that define the ‘contemporary condition’ of intensified global computation, technological interconnectedness and the ontogenesis of sensor-media milieus, their respective temporalities and concomitant aesthetics of experienced time.

In this Monograph, Eva Bonda proposes a new theory of the sense of ‘touch’ in Aristotle’s foundational treatise ‘Περὶ Ψυχῆς’ (On the Soul). The author argues that a delve into the aristoteleian lexicon reveals an intrinsically dialectical theory of the senses, that of all senses being reduced to ‘touch’ either as an experience of polysensoriality or synaeshthesia or of remote sensing touch. ‘Touch’ becomes in Aristotle the thread connecting the matter to its transmutation into the abstract mind. On the (...) basis of neuroimaging results, Eva Bonda describes how the human brain codes, as intangible cognitive phenomena, the body image and the memory through touch. The Monograph is based in Author’s participation at the 2016 World Conference ‘Aristotle 2400 years from his birth’, organized by Aristotle University of Thessaloniki in Greece on 23-28 May 2016.

In this paper, we identify and discuss some of the ethical problems associated with digital sensors used to detect water contamination and air pollution in the United States. Such safety devices are often deployed unsystematically and with questionable efficacy, thereby structuring the life chances of people in unequal ways. Whereas most technological infrastructures are hidden from view . or at least from active awareness . until they cease to function, those infrastructures meant to monitor and/or regulate largely "invisible" public health (...) dangers resist public awareness even when they fail. Because such detection systems tend to indivi-dualize responsibility for reducing risk, the systems may normalize and perhaps exacerbate root problems of contamination and unequal exposure. One ethical challenge is to render such systems and their failures legible. (shrink)

Psalm 73 is a challenging Psalm in which the Psalmist draws on rich imagery to juxtapose doctrine and experience and to juxtapose the goodness of God with divine retribution. Drawing on data provided by 15 theological educators within the Anglican Diocese of Cyprus and the Gulf, this study tests the thesis that the imagery of Psalm 73 will be perceived differently by sensing types and by intuitive types and that the issue ‘Is God really good to the upright?’ will (...) be judged differently by feeling types and by thinking types. The findings from this study are consistent with the broader hermeneutical theory that the psychological type profile of the reader, in terms of perceiving preference and judging preference, plays a formative part in shaping the interpretation of biblical material.Contribution: Situated within the reader-perspective approach to biblical hermeneutics, the SIFT method is concerned with identifying the influence of the psychological type of the reader in shaping the interpretation of text. The present study demonstrates that this theory holds true for the way in which theological educators read Psalm 73. (shrink)
