The screen continues to be the primary generator of visual imagery in contemporary culture, including of the natural world. This paper examines the screen as visual interface in the construction and consumption of physical environments. Screens are increasingly incorporated in our daily habits and imbricated into our lives, especially as mediating technologies are embedded into the surfaces of our physical surroundings, shaping and molding our interactions with and perceptions of those environments. As screens become increasingly portable and digitized, they further (...) modify our relationships with environments, projecting multiple images and imagery which fracture and layer visual consumption. And as screens become ubiquitous in urban environments, they network into maps of information control and consumption. We need to fully understand these processes of screen-mediated representation and interaction in order to be able to comment on the ethics of contemporary practices of visually consuming physical environments. In particular, the paper will argue that processes of consumption and their interaction with visual interfacing technologies are not simple or straight-forward, but nevertheless pose ethical questions about the relationship between visual and material circuits of consumption.

Search can be found in almost every cognitive activity, ranging across vision, memory retrieval, problem solving, decision making, foraging, and social interaction. Because of its ubiquity, research on search has a tendency to fragment into multiple areas of cognitive science. The proposed topic aims at providing integrative discussion of the central role of search from multiple perspectives. We focus on controlled search processes, which require a goal, uncertainty about the nature, location, or acquisition method of the objects to be searched (...) for, and a method for sampling through the search environment. While this definition of search is general and applicable to different domains, the specific mechanisms in the search process will likely differ. The goal of this issue is to compare and contrast how these search processes are similar and differ in different cognitive activities, with the goal of understanding the general nature of search in terms of the three characteristics stated above. We expect that given its cross-domain nature, the topic on search will be of broad interest to cognitive scientists, including psychologists, behavioral ecologists, computer scientists, neuroscientists, linguists, and sociologists.

This paper presents an approach to managing knowledge specific to a particular location for complex instruments. The goal is to improve the knowledge communication between experts and end-users of scientific instruments. We propose a computational framework that integrates augmented reality and augmented virtuality as interface for manipulating knowledge. The augmented virtuality-based interface can be produced and distributed without extra costs. It allows knowledge dissemination at a larger scale. The prominent feature of our model is that the knowledge representation is independent (...) from those interfaces. A preliminary version of our framework has been implemented and deployed in customers’ environments. (shrink)

Expert systems have had little impact as computing artifacts. In this paper we argue that the reason for this stems from the underlying assumption of most builders of expert systems that an expert system needs to acquire information and to control the interaction between the human user and itself. We show that this assumption has serious linguistic and usability flaws which diminish the likelihood of producing socially acceptable expert systems. We propose a reversal of this paradigm, for the design of (...) expert systems, by assuming that it is the human user who needs to acquire information and to control the interaction between themselves and the system.

I argue that the concept of an epistemic interface is a useful one to add to the epistemic ecology toolkit in order to enrich our investigations concerning the complex epistemic phenomena arising on social media. An epistemic interface is defined as any informational interface (be it technical, human or institutional) that facilitates the transfer of epistemic goods from one epistemic environment to its outside, be that another epistemic environment or a person. When assessing the kinds of epistemic environments (...) emerging on social media platforms, we should not only look at their epistemic health or hostility as environments, but also look at how these environments interact with each other, at their interfacing. I show that several epistemic problems specific to social media such as epistemic bubbles, echo chambers and epistemic flooding can be understood also in terms of faulty epistemic interfacing, which adds a layer of complexity to the discussion. The paper proposes two criteria for healthy epistemic interfacing: preserving the flourishing of epistemic agents, and preserving in some form the value of epistemic outcomes as these cross the environment to the outside world. These criteria should give rise to specific norms and design requirements for healthy interfacing, but such norms will need more empirical work before these get formulated. (shrink)

As digital and immersive architectural installations and augmented reality applications generate new sensations, new digital dimensions and boundaries create new perceptions of our built environment. Digital architectural installations as immersive environments make data visible and tangible and give access to data as an experiential flow. Like the works of Refik Anadol, TeamLab or Universal Everything, digital architectural installations point to a neuroarchitectural and neurophenomenological atmosphere that refers to the understanding and measurement of embodied human experience, and how spaces affect (...) people and how they behave in a given setting. The objectivity of the screen allows viewers to observe through screens, and the screen as an ambivalent object provides a physical interface that transcends the shadow of its materiality, transforming the viewer’s environmental perception. Therefore, this article examines digital architectural environments that reveal the boundaries of architectural space, with particular consideration given to neuroaesthetics. In these data-driven environments, the human body is at the centre of multimodal perception. Therefore, these environments open the door to understanding the boundaries of architecture and invite the viewers to explore the boundaries of art and architecture that have become a fusion in the digital environment.

This article interrogates the interface between the older Pentecostal movement and politics in Zimbabwe. The country continues to face political violence and a breakdown in rule of law. The Zimbabwean populace is asking whether the Zimbabwean Pentecostal movement is ready and able to exercise its prophetic role in promoting real peace and democracy. Many Zimbabweans are asking this question, because the track record shows that whilst most mainline churches have been consistent in becoming the voice of the voiceless, some Zimbabwean (...) Pentecostal churches seem to have been sitting on the fence for too long by adopting a middle of the road stance, thereby avoiding a head-on confrontation with the corrupt Zimbabwe African National Union–Patriotic Front government. In this article, I argue that for many decades the Zimbabwean Pentecostal movement has taken what one might refer to ironically as a ‘smart approach to politics’–in which the image of the ZANU–PF government is sanitised by espousing what I call a ‘spiritualised political theology.’ I use this critique, whilst remaining cognisant of the fact that the primary motivation of the movement on which I focus in this article, was evangelism, not politics. Thus, for the purpose of this research, the Zimbabwe Assemblies of God Africa of Apostle Ezekiel Guti was sampled to investigate its prophetic voice in a polarised political environment. This article examines the history of Apostle Guti’s political subterfuge based on the reflections of his pastoral letters referred to as the ‘Ten-days prayer letters’ issued since 1975 up to the time of writing this article. It is important at this early stage to outline that these letters were not political statements or meant to address politics only but theological letters addressing different social ills including politics. Thus, reading this letter one shall see that Apostle’s political subterfuge demonstrated a continuous oscillation of a theological position on how the church should relate to politics. Furthermore, I undertake a brief examination of other few millennial Zimbabwean Pentecostal churches to see if this political subterfuge transcended elsewhere thereby propagating a spiritualised political theology.Contribution: What is key to note is the fact that the Zimbabwean Pentecostal movement remained insignificant with regard to democratization agenda even after the removal of President Mugabe. The above claim is evidenced by the Zimbabwean Pentecostal church founders’ continuous political subterfuge authenticated by a propagation of a spiritualized political theology. (shrink)

Interaction between drivers and pedestrians is often facilitated by informal communicative cues, like hand gestures, facial expressions, and eye contact. In the near future, however, when semi- and fully autonomous vehicles are introduced into the traffic system, drivers will gradually assume the role of mere passengers, who are casually engaged in non-driving-related activities and, therefore, unavailable to participate in traffic interaction. In this novel traffic environment, advanced communication interfaces will need to be developed that inform pedestrians of the (...) current state and future behavior of an autonomous vehicle, in order to maximize safety and efficiency for all road users. The aim of the present review is to provide a comprehensive account of empirical work in the field of external human–machine interfaces for autonomous vehicle-to- pedestrian communication. In the great majority of covered studies, participants clearly benefited from the presence of a communication interface when interacting with an autonomous vehicle. Nevertheless, standardized interface evaluation procedures and optimal interface specifications are still lacking. (shrink)

The objective of this article is to reflect on the application of Semiotics to Human-Computer Interaction (HCI) and interface analysis. To accomplish the objective the article presents an example of semiotic analysis of a blog interface but the methodology proposed, conveniently adapted, may be applied to any kind of digital interactive environment. The analysis reconstructs the interface sense production device (including the surface of the page and the link architecture), identifies implied users and exchange scenes of the blog and (...) concludes with some reflections on interface evolution and hybridation. Finally, the article proposes future trends for a Semiotics of HCI. (shrink)

This study explored the effect of kinesthetic motor imagery training on reaching-to-grasp movement supplemented by a virtual environment in a patient with congenital bilateral transverse upper-limb deficiency. Based on a theoretical assumption, it is possible to conduct such training in this patient. The aim of this study was to evaluate whether cortical activity related to motor imagery of reaching and motor imagery of grasping of the right upper limb was changed by computer-aided imagery training in a patient who was (...) born without upper limbs compared to a healthy control subject, as characterized by multi-channel electroencephalography signals recorded before and 4, 8, and 12 weeks after CAIT. The main task during CAIT was to kinesthetically imagine the execution of reaching-to-grasp movements without any muscle activation, supplemented by computer visualization of movements provided by a special headset. Our experiment showed that CAIT can be conducted in the patient with higher vividness of imagery for reaching than grasping tasks. Our results confirm that CAIT can change brain activation patterns in areas related to motor planning and the execution of reaching and grasping movements, and that the effect was more pronounced in the patient than in the healthy control subject. The results show that CAIT has a different effect on the cortical activity related to the motor imagery of a reaching task than on the cortical activity related to the motor imagery of a grasping task. The change observed in the activation patterns could indicate CAIT-induced neuroplasticity, which could potentially be useful in rehabilitation or brain-computer interface purposes for such patients, especially before and after transplantation. This study was part of a registered experiment. (shrink)

In The Interface Envelope, James Ash develops a series of concepts to understand how digital interfaces work to shape the spatial and temporal perception of players. Drawing upon examples from videogame design and work from post-phenomenology, speculative realism, new materialism and media theory, Ash argues that interfaces create envelopes, or localised foldings of space time, around which bodily and perceptual capacities are organised for the explicit production of economic profit. Modifying and developing Bernard Stiegler's account of psychopower and (...) Warren Neidich's account of neuropower, Ash argues the aim of interface designers and publishers is the production of envelope power. Envelope power refers to the ways that interfaces in games are designed to increase users perceptual and habitual capacities to sense difference. Examining a range of examples from specific videogames, Ash identities a series of logics that are key to producing envelope power and shows how these logics have intensified over the last thirty years. In turn, Ash suggests that the logics of interface envelopes in videogames are spreading to other types of interface. In doing so life becomes enveloped as the environments people inhabit becoming increasingly loaded with digital interfaces. Rather than simply negative, Ash develops a series of responses to the potential problematics of interface envelopes and envelope power and emphasizes their pharmacological nature. (shrink)

Though they have much in common, the fields of organizational effectiveness (OE) and corporate social performance (CSP) have developed independently. Although both areas deal with organization-environment interactions, each focus is different-OE focuses on how an organization "manages" its environment for its own ends whereas CSP focuses on an organization's responsibilities to, and performance vis-a-vis, its environment. Scholars within the two fields, therefore, have tended to take parallel, nonintersecting paths and, thus, have overlooked potential synergies. In calling attention (...) to potental conceptual and empirical development at the intersection of OE and CSP, the authors examine similarities and differences between the two domains, propose a framework for analyzing congruity between an organization's functional and social performance, present illustrative cases to demonstrate the benefits of considering the OE-CSP interface, and suggest guidelines for conducting research at the OE-CSP interface.

Context: The evolution of perceptual systems and hence of observers remains largely disconnected from the question of the emergence of classical objects and spacetime. This disconnection between the biosciences and physics impedes progress toward understanding the role of the “observer” in physical theory. Problem: In this article we consider the problem of how to understand objects and spacetime in observer-relative evolutionary terms. Method: We rely on a comparative analysis using multiple formal frameworks. Results: The eigenform construct of von Foerster is (...) compared to other formal representations of observer-environment interactions. Eigenforms are shown to be encoded on observer-environment interfaces and to encode fitness consequences of actions. Space and time are components of observational outcomes in this framework; it is suggested that spacetime constitutes an error-correcting code for fitness consequences. Implications: Our results contribute to an understanding of the world in which neither objects nor spacetime are observer-independent. Constructivist content: The eigenform concept of von Foerster is linked to the concepts of decoherence and holographic encoding from physics and the concept of fitness from evolutionary biology.

Most philosophers appear to have ignored the distinction between the broad concept of Virtual Machine Functionalism (VMF) described in Sloman&Chrisley (2003) and the better known version of functionalism referred to there as Atomic State Functionalism (ASF), which is often given as an explanation of what Functionalism is, e.g. in Block (1995). -/- One of the main differences is that ASF encourages talk of supervenience of states and properties, whereas VMF requires supervenience of machines that are arbitrarily complex networks of causally (...) interacting (virtual, but real) processes, possibly operating on different time-scales, examples of which include many different procesess usually running concurrently on a modern computer performing various tasks concerned with handling interfaces to physical devices, managing the file system, dealing with security, providing tools, entertainments, and games, and possibly processing research data. Another example of VMF would be the kind of functionalism involved in a large collection of possibly changing socio-economic structures and processes interacting in a complex community, and yet another is illustrated by the kind of virtual machinery involved in the many levels of visual processing of information about spatial structures, processes, and relationships (including percepts of moving shadows, reflections, highlights, optical-flow patterns and changing affordances) as you walk through a crowded car-park on a sunny day: generating a whole zoo of interacting qualia. (Forget solitary red patches, or experiences thereof.) -/- Perhaps VMF should be re-labelled "Virtual MachinERY Functionalism" because the word 'machinery' more readily suggests something complex with interacting parts. VMF is concerned with virtual machines that are made up of interacting concurrently active (but not necessarily synchronised) chunks of virtual machinery which not only interact with one another and with their physical substrates (which may be partly shared, and also frequently modified by garbage collection, metabolism, or whatever) but can also concurrently interact with and refer to various things in the immediate and remote environment (via sensory/motor channels, and possible future technologies also). I.e. virtual machinery can include mechanisms that create and manipulate semantic content, not only syntactic structures or bit patterns as digital virtual machines do. -/- Please note: Click on the title above or the link below to read the paper.

The brain–computer interface (BCI) has made remarkable progress in the bridging the divide between the brain and the external environment to assist persons with severe disabilities caused by brain impairments. There is also continuing philosophical interest in BCIs which emerges from thoughtful reflection on computers, machines, and artificial intelligence. This article seeks to apply BCI perspectives to examine, challenge, and work towards a possible resolution to a persistent problem in the mind–body relationship, namely dualism. The original humanitarian goals of (...) BCIs and the technological inventiveness result in BCIs being surprisingly useful. We begin from the neurologically impaired person, the problems encountered, and some pioneering responses from computers and machines. Secondly, the interface of mind and brain is explored via two points of clarification: direct and indirect BCIs, and the nature of thoughts. Thirdly, dualism is beset by mind–body interaction difficulties and is further questioned by the phenomena of intentions, interactions, and technology. Fourthly, animal minds and robots are explored in BCI settings again with relevance for dualism. After a brief look at other BCIs, we conclude by outlining a future BCI philosophy of brain and mind, which might appear ominous and could be possible. (shrink)

Recently, the relationship between evolutionary ecology and perceptual science has received renewed attention under perception-mediated selection, a mode of natural selection linking perceptual saliency, rather than veridicality, to fitness. The Interface Theory of Perception (ITP) has been especially prominent in claiming that an organism’s perceptual interface is populated by icons, which arise as a function of evolved, species-specific perceptual interfaces that produce approximations of organisms’ environments through fitness-tuned perceptions. According to perception-mediated selection, perception and behavior calibrate one another as (...) organisms’ capacities to experience and know the objects and properties of their environments lead to responses highlighting certain environmental features selected for survival. We argue this occurs via the Umwelt/Umgebung distinction in ethology, demonstrating that organisms interact with their external environments (Umgebung) through constructed perceptual schema (Umwelt) that produce constrained representations of environmental objects and their properties. Following Peircean semiotics, we claim that ITP’s focus on icons as saliency-simplified markers corresponds to biosemiotics’ understanding of perceptual representations, which manifest as iconic (resembling objects), indexical (referring), or symbolic (arbitrary) modalities, which provide for organisms’ semiotic scaffolding. We argue that ITP provides the computational evidence for biosemiotics’ notion of iconicity, while biosemiotics provides explanation within ITP for how iconicity can build up into indices and symbols. The common contention of these separate frameworks that the process of perception tracks saliency rather than veridicality suggests that digital/dyadic perceptual strategies will be outcompeted by their semiotic/triadic counterparts. This carries implications for evolutionary theory as well as theories of cognition. (shrink)

This volume summarizes the ethical, social and cultural contexts of interfacing brains and computers. It is intended for the interdisciplinary community of BCI stakeholders. Insofar, engineers, neuroscientists, psychologists, physicians, care-givers and also users and their relatives are concerned. For about the last twenty years brain-computer-interfaces (BCIs) have been investigated with increasing intensity and have in principle shown their potential to be useful tools in diagnostics, rehabilitation and assistive technology. The central promise of BCI technology is enabling severely impaired people (...) in mobility, grasping, communication, and entertainment. Successful applications are for instance communication devices enabling locked-in patients in staying in contact with their environment, or prostheses enabling paralysed people in reaching and grasping. In addition to this, it serves as an introduction to the whole field of BCI for any interested reader. (shrink)

The last decade has seen the dawn of a technological development towards a wireless-networked world. Various mobile interfaces have started to appear like laptop computer, PDA, mobile phone, Blueberry. The zenith of this development is the full distribution of computation and networks into every aspect of our life. Everything will become an interface, from a cup to a shirt. Wireless networks and multifarious interfaces will blend invisibly into our everyday life and environment. This emerging infrastructure and its (...) significant impact on our life provide new conditions for artistic practice. What kind of artworks and art forms are emerging from this situation? How does this technological development reflect on artistic practice? The ideas from the late 1960s and early 1970s art theory about immateriality seem to be a promising starting point. They are relevant to contemporary artists working with digital technologies. These artists are employing a new set of forms and media, which are increasingly immaterial. The nature of art and objects, how we relate to and read them, has changed. This paper is an investigation into immateriality versus materiality mainly focusing on mobile art. It looks at the situation from the viewpoint of an artist a maker and thinker of things and objects. The text is divided into four sections. The first section introduces few cases, which have been concerned about immateriality in art from the recent 40 years of art history. The second section talks about artistic practices, which focus on mobile art and mobile technologies. The third section is about transformation of objects, and the text ends with an assumption about the role of the artist. (shrink)

Human–wildlife interactions have existed for thousands of years, however as human populations increase and human impact on natural ecosystems becomes more intensive, both parties are increasingly being forced to compete for resources vital to both. Humans can value wildlife in many contexts promoting coexistence, while in other situations, such as crop-raiding, wildlife conflicts with the interests of people. As our closest phylogenetic relatives, chimpanzees in particular occupy a special importance in terms of their complex social and cultural relationship with humans. (...) A case study is presented that focuses on the Bossou chimpanzees’ perspective of their habitat in the Republic of Guinea, West Africa, by highlighting the risks and opportunities presented by a human-dominated landscape, and detailing their day-to-day coexistence with humans. Understanding how rural people perceive chimpanzees and how chimpanzees adapt to living in anthropogenic environments will enhance our understanding of how people-wildlife interactions develop into situations of conflict and therefore can generate sustainable solutions to prevent or mitigate situations of conflict.

Two proposals regarding what the primary psychological interface is are critically discussed. One proposal posits an actual overlap of consciousness and reality. The parts of the physical world that are directly perceived, or "self-given" — given themselves in person — to perceptual consciousness, are also elements of that consciousness. Each such part is supposed to have a kind of double existence, in the physical world and also in consciousness. Against this view, I argue that perceptual awareness makes portions of the (...) physical world self-given only in their being manifested or appearing in consciousness, whereas the portions themselves remain completely external to consciousness. Other authors claim that the primary psychological interface is an animal’s perceptual activity with respect to the ecological environment. But, this interface does not amount, for them, to the animal’s perceptual awareness in the familiar, ordinary sense of the experiencing of things by means of the senses, or as theoretically conceived of by the act psychologists of the nineteenth century; rather, perceptual awareness is a feature of the animal’s actions upon the ecological environment. Against this view, I argue that an occurrent perceptual awareness is a central, unperceivable product and part of a larger activity of perceiving and an element of the actual interface between reality and consciousness.

How do we understand the agency and significance of material forces and their interface with human bodies? What does it mean to be human in these times, with bodies that are inextricably interconnected with our physical world?

Smart homes create a beneficial environment for the lives of elderly people and enhance the quality of their home lives. This study aims to explore the design of age-friendly interfaces that can meet the emotional needs of self-care elderly people from the perspective of functional realization of the operating interface. Sixteen elderly users aged fifty-five and above were selected as subjects with healthy eyes and no excessive drooping eyelids to obscure them. Four representative age-friendly applications with different interface (...) designs were selected from the Android application market as the stimulus material for the experiment, and a total of fifteen pages were browsed independently. During the experiment, the ErgoLAB human-computer environment synchronization cloud platform was used to monitor and record the subjects' multidimensional physiological indicators of eye movements, skin electricity, and heart rate variability when using different styles of mobile application interfaces. Combined with the post-experimental PAD emotion scale data, the preferences of emotional interface design elements of the self-care elderly were analyzed to guide the subsequent design practice. The results show that: on the layout characteristics of the home page, a simple and intuitive multi-column layout or card layout combined with a bottom navigation bar type main navigation is used; on the choice of the main color, a single color with low saturation is used as the main color, with high saturation color accents to play a role in highlighting key information; on the information density of the home page, a moderate proportion of graphics and text is adopted, with low information density; on the arrangement of the page content, they try to give priority to information content with high user relevance.

If our choices make us who we are, then what does that mean when these choices are made in the human-machine interface? Developing a clear understanding of how human decision making is influenced by automated systems in the environment is critical because, as human-machine interfaces and assistive robotics become even more ubiquitous in everyday life, many daily decisions will be an emergent result of the interactions between the human and the machine – not stemming solely from the human. (...) For example, choices can be influenced by the relative locations and motor costs of the response options, as well as by the timing of the response prompts. In drift diffusion model simulations of response-prompt timing manipulations, we find that it is only relatively equibiased choices that will be successfully influenced by this kind of perturbation. However, with drift diffusion model simulations of motor cost manipulations, we find that even relatively biased choices can still show some influence of the perturbation. We report the results of a two-alternative forced-choice experiment with a computer mouse modified to have a subtle velocity bias in a pre-determined direction for each trial, inducing an increased motor cost to move the cursor away from the pre-designated target direction. With queries that have each been normed in advance to be equibiased in people’s preferences, the participant will often begin their mouse movement before their cognitive choice has been finalized, and the directional bias in the mouse velocity exerts a small but significant influence on their final choice. With queries that are not equibiased, a similar influence is observed. By exploring the synergies that are developed between humans and machines and tracking their temporal dynamics, this work aims to provide insight into our evolving decisions. (shrink)

Alongside existing research into the social, political and economic impacts of the Web, there is a need to study the Web from a cognitive and epistemic perspective. This is particularly so as new and emerging technologies alter the nature of our interactive engagements with the Web, transforming the extent to which our thoughts and actions are shaped by the online environment. Situated and ecological approaches to cognition are relevant to understanding the cognitive significance of the Web because of the (...) emphasis they place on forces and factors that reside at the level of agent–world interactions. In particular, by adopting a situated or ecological approach to cognition, we are able to assess the significance of the Web from the perspective of research into embodied, extended, embedded, social and collective cognition.

The way information is perceived and defined today is no longer an accurate portrayal of the interactions occurring among user–information–interface. We are so accustomed to the traditional models of human–machine interactions that we often overlook the fact that first- and second-order cybernetics definitions are now antiquated and one-dimensional when used to describe user–information–interface interactions. Within this new era of user–information–interface relationship, the introduction of the concept of Meta-Environment reflects a more accurate representation of the processes of information gathering and (...) sharing and their interactions. Meta-Environments break the mold of traditional thinking and refocus attention not on the user, information or interface alone, but on the relationships and processes as a whole. It expands cybernetics to its fourth order while focusing on the relationship among user-information-interface as a Complex Adaptive System. (shrink)

Cohesion is established in S‐phase through the action of key replisome factors as replication forks engage cohesin molecules. By holding sister chromatids together, cohesion critically assists both an equal segregation of the duplicated genetic material and an efficient repair of DNA breaks. Nonetheless, the molecular events leading the entrapment of nascent chromatids by cohesin during replication are only beginning to be understood. The authors describe here the essential structural features of the cohesin complex in connection to its ability to associate (...)

Background Dynamic consent has been proposed as a process through which participants and patients can gain more control over how their data and samples, donated for biomedical research, are used, resulting in greater trust in researchers. It is also a way to respond to evolving data protection frameworks and new legislation. Others argue that the broad consent currently used in biobank research is ethically robust. Little empirical research with cohort study participants has been published. This research investigated the participants’ opinions (...) of adding a dynamic consent interface to their existing study. Methods Adult participants in the Extended Cohort for E-health, Environment and DNA longitudinal cohort study who are members of the EXCEED Public and Participant Engagement Group were recruited. Four focus groups were conducted and analysed for thematic content. Discussion topics were derived from a review of the current literature on dynamic consent. Results Participants were in favour of many aspects of a dynamic consent interface, such as being able to update their information, add additional data to their records and choose withdrawal options. They were supportive provided it was simple to use and not intrusive. Participants expressed a markedly high level of trust in the study and its investigators and were unanimously happy with their current participation. No strong support was found for adding a dynamic consent interface to EXCEED. Conclusions Trust in the study researchers was the strongest theme found. Openness and good data security were needed to retain their trust. While happy to discuss dynamic consent, participants were satisfied with the current study arrangements. There were indications that changing the study might unnecessarily disturb their trust. This raised the question of whether there are contexts where dynamic consent is more appropriate than others. This study was limited by the small number of participants who were committed to the study and biased towards it. More research is needed to fully understand the potential impact of adding a dynamic consent interface to an existing cohort study. (shrink)

Brain-computer interfaces are communication bridges between a human brain and external world, enabling humans to interact with their environment without muscle intervention. Their functionality, therefore, depends on both the BCI system and the cognitive capacities of the user. Motor-imagery BCIs rely on the users’ mental imagination of body movements. However, not all users have the ability to sufficiently modulate their brain activity for control of a MI-BCI; a problem known as BCI illiteracy or inefficiency. The underlying mechanism of (...) this phenomenon and the cause of such difference among users is yet not fully understood. In this study, we investigated the impact of several cognitive and psychological measures on MI-BCI performance. Fifty-five novice BCI-users participated in a left- versus right-hand motor imagery task. In addition to their BCI classification error rate and demographics, psychological measures including personality factors, affinity for technology, and motivation during the experiment, as well as cognitive measures including visuospatial memory and spatial ability and Vividness of Visual Imagery were collected. Factors that were found to have a significant impact on MI-BCI performance were Vividness of Visual Imagery, and the personality factors of orderliness and autonomy. These findings shed light on individual traits that lead to difficulty in BCI operation and hence can help with early prediction of inefficiency among users to optimize training for them. (shrink)

This article focuses on the pendulum-like change in the way people read and use text, which was triggered by the introduction of new reading and writing technologies in human history. The paper argues that textual features, which characterized the ancient pre-print writing culture, disappeared with the establishment of the modern-day print culture and has been “revived” in the digital post-modern era. This claim is based on the analysis of four cases which demonstrate this textual-pendulum swing: (1) The swing from concrete (...) iconic-graphic representation of letters and words in the ancient alphabet to abstract phonetic representation of text in modern eras, and from written abstract computer commands “back” to the concrete iconic representation in graphic user interfaces of the digital era; (2) The swing from scroll reading in the pre-print era to page or book reading in the print era and “back” to scroll reading in the digital era; (3) The swing from a low level of authorship in the pre-print era to a strong authorship perception in the print era, and “back” to a low degree of authorship in the digital era; (4) The swing from synchronic representation of text in both visual and audio formats during the pre-print era to a visual representation only in print, and “back” to a synchronic representation in many environments of the digital era. We suggest that the print culture, which is usually considered the natural and preferred textual environment, should be regarded as the exception. (shrink)

Multimedia technology offers instructional designers an unprecedented opportunity to create richly interactive learning environments. With greater design freedom comes complexity. The standard answer to the problems of too much choice, disorientation, and complex navigation is thought to lie in the way we design interactivity in a system. Unfortunately, the theory of interactivity is at an early state of development. After critiquing the decision cycle model of interaction—the received theory in human computer interaction—I present arguments and observational data to show that (...) humans have several ways of interacting with their environments, which resist accommodation in the decision cycle model. These additional ways of interacting include: preparing the environment, maintaining the environment, and reshaping the cognitive congeniality of the environment. Understanding how these actions simplify the computational complexity of our mental processes is the first step in designing the right sort of resources and scaffolding necessary for tractable learner controlled learning environments.

This volume presents studies on pronouns in embedded contexts, and offers fundamental insights into this central area of research. Much of the recent research on pronouns has shown that embedded environments, such as clausal complements of attitude predicates, provide a window into the nature of pronouns. Pronouns in such environments not only exhibit familiar distinctions such as that between bound and referential pronouns; if they refer to the attitude holder, they also participate in a broader range of phenomena, e.g., distinguishing (...) between a de se reading and a de re reading. Topics covered include: the semantics of attitude reports that contain pronominal elements, the semantics of pronominal features and their connection to indexicality, new insights in the connection of pronominal typology and logophoricity or anti-logophoricity, and finally, the localization of embedded pronouns within a bigger picture involving the nature of perspective and the analysis of quasi-pronominal phenomena such as sequence of tense.

Virtual environment landmarks are essential in wayfinding: they anchor routes through a region and provide memorable destinations to return to later. Current virtual environment browsers provide user interface menus that characterize available travel destinations via landmark textual descriptions or thumbnail images. Such characterizations lack the depth cues and context needed to reliably recognize 3D landmarks. This paper introduces a new user interface affordance that captures a 3D representation of a virtual environment landmark into a 3D thumbnail, called (...) a worldlet. Each worldlet is a miniature virtual world fragment that may be interactively viewed in 3D, enabling a traveler to gain first-person experience with a travel destination. In a pilot student conducted to compare textual, image, and worldlet landmark representations within a wayfinding task, worldlet use significantly reduced the overall travel time and distance traversed, virtually eliminating unnecessary backtracking.

Our use of artefacts has at different moments been characterised as either replacing or impoverishing our natural human capacities, or a key part of our humanity. This article critically evaluates the conception of the natural invoked by both accounts, and highlights the degree to which engagement with material features of the environment is fundamental to all living things, the closeness of this engagement making any account that seeks to draw a clear boundary between body and artefact problematic. By doing (...) this I seek to clarify the nature of our embodied relationship with various kinds of artefacts; moving from tools to machines to digital interfaces, I consider their differing potentials to be gathered into the body schema, and thus change our embodied horizons of perception and action. While much research currently seeks to facilitate a more ‘natural’ mode of interacting with technology, I argue that such a mode of interaction does not exist outside the particularity of our relationships with specific objects. As a result, rather than trying to cater to supposedly more natural modes of action and perception, future technologies should aim to enrich our experience with new modes, inviting novel relationships that produce new kinds of sensory and other experience.

Contributions are rooted in real-world contexts and problems, explored through detailed ethnographic work. Explores domains as diverse as allotments and bioinvasion, fox hunting and green politics. Makes a distinctive contribution to the ‘cultural (...) turn’ in environmental research. (shrink)

There are two main paradigms for brain-related science, with different implications for brain-focused intervention or advancement. The paradigm of homeostasis (“stability through constancy,” Walter Cannon), originating from laboratory-based experimental physiology pioneered by Claude Bernard, shows that living systems tend to maintain system functionality in the direction of constancy (or similitude). The aim of physiology is elucidate the factors that maintain homeostasis, and therapeutics aim to correct abnormal factor functions. The homeostasis paradigm does not formally recognize influences outside its controlled experimental (...) frames and it is variable in its modelling of neural contributions. The paradigm of allostatic orchestration (PAO) extends the principle of allostasis (“stability through change”) as originally put forth by Peter Sterling. The PAO originates from an evolutionary perspective and recognizes that biological set points change in anticipation of changing environments. The brain is the organ of central command, orchestrating cross-system operations to support optimal behavior at the level of the whole organism. Alternative views of blood pressure regulation and posttraumatic stress disorder illustrate differences between the paradigms. For the PAO, complexities of top-down neural effects and environmental context are foundational (not to be “factored out”), and anticipatory regulation is the principle of their interface. The allostatic state represents the integrated totality of brain-body interactions. Health itself is an allostatic state of optimal anticipatory oscillation, hypothesized to relate to the state of criticality, a mathematical point of poise between phases, on the border between order and disorder (or the “edge of chaos”). Diseases are allostatic states of impaired anticipatory oscillations, demonstrated as rigidifications of set points across the brain and body (disease comorbidity). Conciliation of the paradigms is possible, with “reactive homeostasis” resolved as an illusion stemming from anticipation of environmental monotony. Considerations are presented with respect to implications of the two paradigms for brain-focused intervention or advancement; the hypothesis that the state of criticality is a vehicle for evolutionary processes; concordance with a philosophy of freedom based on ethical individualism as well as self-creativity, non-obsolescence, empowerment, and citizenship; and concluding reflections on the science and ethics of the placebo, and the potential for virtuous cycles of brain-Anthropocene interactions.

The growing popularization of stakeholder theory among management scholars has offered a useful framework for understanding the multiple and interdependent roles of government and business in an increasingly challenging political and regulatory environment. Despite this trend, attention to the role and responsibility of government to protect citizen rights has been limited. To the two traditional stakeholder theory views of government where the focal organization remains the firm, we propose to add two views by pivoting the government’s place and making (...) it the focal organization. We thus describe governments as serving four roles in the business–government–society nexus. For each role, we analyze typical governmental activities/behaviors, relationships with firms’ stakeholders, as well as the challenges and limits to these roles. We also focus on the central notion of salience amplification, as a means of checks and balances across stakeholders in order to safeguard citizen rights and reveal the greater good. (shrink)

Corporate social responsibility (CSR) concerns the realm of business behavior in which the firm tries to effectively manage its business and non-market environment interface. Coerced CSR refers to taking socially responsible action in response to or in anticipation of retaliation in some form (boycott, adverse publicity, introduction of regulatory laws, etc.) from interest groups who are not directly part of the market to which the firm caters. In contrast, strategic CSR or altruistic CSR refers to socially responsible activities undertaken (...) out of enlightened self-interest. The focus of this paper is to understand whether the impact of coercion is different for government-owned organizations and privately owned firms in developing countries. Activities that are in response to or in anticipationof threats by interest groups are identified and compared across publicly and privately owned firms, against the backdrop of weak enforcement of fairly stringent environmental regulation. We then generalize our observations and attempt to distinguish the intensity of pressures felt by public and privately owned firms and their speed of response. As a result of this understanding, we attempt to suggest specific policy mixes for various types of industry, depending on whether they are dominated by the public sector or private sector. (shrink)

We consider, from a physical perspective, the case where the interface between an organism and its environment becomes large enough that it acts as a buffer regulating their matter and energy exchanges. We illustrate the physiological and evolutionary role of buffers through the example of lungfish estivation. Then we ponder the relevance of buffers of this kind to the quest for a general definition of concepts like niche construction, the extended phenotype, and related ones, whose meaning is conveyed at (...) present mostly through particular examples. Finally, we comment on the potential significance of buffers to organism—environment codetermination in the sense originally suggested by Lewontin. (shrink)

Brain Computer Interfaces (BCIs) enable one to control peripheral ICT and robotic devices by processing brain activity on-line. The potential usefulness of BCI systems, initially demonstrated in rehabilitation medicine, is now being explored in education, entertainment, intensive workflow monitoring, security, and training. Ethical issues arising in connection with these investigations are triaged taking into account technological imminence and pervasiveness of BCI technologies. By focussing on imminent technological developments, ethical reflection is informatively grounded into realistic protocols of brain-to-computer communication. In (...) particular, it is argued that human-machine adaptation and shared control distinctively shape autonomy and responsibility issues in current BCI interaction environments. Novel personhood issues are identified and analyzed too. These notably concern (i) the “sub-personal” use of human beings in BCI-enabled cooperative problem solving, and (ii) the pro-active protection of personal identity which BCI rehabilitation therapies may afford, in the light of so-called motor theories of thinking, for the benefit of patients affected by severe motor disabilities.

Ecological developmental biology considers the phenotype as actively produced through an environmentally informed process of individual development, rather than predetermined by the genotype. Accordingly, the genotype is viewed as one among many interactants that contribute formative elements; it is understood to do so no differently from the way other organism-internal and environmental resources do. Although the EcoDevo approach is evidently particularly apt to inform approaches to human development, which mostly takes shape in rich cultural environments, it is remarkable that, at (...) least within some highly influential circles of the linguistic sciences, the study of many distinctive human cognitive traits including language remains strongly anchored to a preformationist stance. This article brings an EcoDevo approach to the biologically focused study of language to argue that an aspect of language design commonly assumed to be “blueprinted,” namely, the lexicon-syntax interface, may instead be explained as a plastic effect of ongoing developmental processes in the mind of the child, in which designated aspects of the environment fulfill a key constructive role.

Therapeutic strategies capable of inducing and enhancing prosthesis embodiment are a key point for better adaptation to and acceptance of prosthetic limbs. In this study, we developed a training protocol using an EMG-based human-machine interface that was applied in the preprosthetic rehabilitation phase of people with amputation. This is a case series with the objective of evaluating the induction and enhancement of the embodiment of a virtual prosthesis. Six men and a woman with unilateral transfemoral traumatic amputation without previous use (...) of prostheses participated in the study. Participants performed a training protocol with the EMG-based HMI, composed of six sessions held twice a week, each lasting 30 mins. This system consisted of myoelectric control of the movements of a virtual prosthesis immersed in a 3D virtual environment. Additionally, vibrotactile stimuli were provided on the participant’s back corresponding to the movements performed. Embodiment was investigated from the following set of measurements: skin conductance response, crossmodal congruency effect, ability to control the virtual prosthesis, and reports before and after the training. The increase in the skin conductance response in conditions where the virtual prosthesis was threatened, recalibration of the peripersonal space perception identified by the crossmodal congruency effect, ability to control the virtual prosthesis, and participant reports consistently showed the induction and enhancement of virtual prosthesis embodiment. Therefore, this protocol using EMG-based HMI was shown to be a viable option to achieve and enhance the embodiment of a virtual prosthetic limb. (shrink)

According to classical theories of language and cognition, human cognition is characterized by strong universal commonalities built around notions such as object, space, agency, number, time, and event (Clark, 1973; Miller & Johnson‐Laird, 1976). Languages select from this prelinguistic conceptual repertoire the concepts that become encoded in their lexical and grammatical stock. Language acquisition, on this view, is a mapping process in which the learner needs to figure out which sounds in the language spoken in the environment correspond to (...) which concepts from the ones already in the mind (Fodor, 1975; Gleitman, 1990; Pinker, 1994).

Over the previous three decades, the area of computer networks has progressed significantly, from traditional static networks to dynamically designed architecture. The primary purpose of software-defined networking is to create an open, programmable network. Conventional network devices, such as routers and switches, may make routing decisions and forward packets; however, SDN divides these components into the Data plane and the Control plane by splitting distinct features away. As a result, switches can only forward packets and cannot make routing decisions; the (...) controller makes routing decisions. OpenFlow is the communication interface between the switches and the controller. It is a protocol that allows the controller to identify the network packet’s path across the switches. This project uses the SDN environment to implement the firefly optimization algorithm to determine the shortest path between two nodes in a network. The firefly optimization algorithm was implemented using Ryu control. The results reveal that using the firefly optimization algorithm improves the selected short path between the source and destination. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Future Environmental Philosophies and Their Biocultural Conservation InterfacesRicardo Rozzi (bio)Perhaps it would be better to speak of the future of environmental philosophies, rather than of the future of environmental philosophy. Making explicit a plurality of future trends helps prevent an "Anglo-academic" bias, and emphasizes the need for further developing environmental philosophy into at least two directions: (1) a stronger dialogical interaction with the diverse international constellation of cultural, ethnic, (...) social, political, economic, and ecological dimensions of environmental problems; and (2) a greater integration into the transdisciplinary field of biological and cultural conservation, involving an enhanced actualization of environmental theoretical philosophy into environmental practical philosophy.1. Toward more multi-discursive international environmental philosophiesFurther developing international environmental philosophy can help [End Page 142] to more precisely identify agents and causes of environmental problems, as well as their effects and victims. For instance, the focus on global climate change—and more generally global change, including other processes of rapid environmental transformation such as biotic, linguistic, and cultural homogenization—should not overlook the fact that different human communities, regions, societies, and countries are not equally responsible for such change nor suffer equally from its consequences. For example, today the highest levels of UV radiation fall on areas of Patagonia and the Antarctic Peninsula. These regions are the farthest away from the centers of CFC emissions which generate the stratospheric ozone hole found over the austral portion of the Americas.1 The incorporation of these type of regional distinctions into environmental philosophy provides the opportunity for more precise diagnoses and characterizations of environmental problems than the still-frequent generalizations stated in terms of problems between "humanity and nature."2 Such a lack of specificity is deceptive because it absolves particular responsible agents of environmental problems by referring to all humans or society in general as responsible for them.Secondly, contrasting ecological, social, and political settings generate not only different environmental problems, but also offer a variety of viable options for solving those problems. This is a point that remains frequently overlooked within global environmental agendas. While working in conservation in Latin America, I am continuously surprised by the marked ecological and cultural singularities I find in different localities in which communities have evolved peculiar ways of understanding, valuing, and interacting with their environments.3 On the one hand, environmental philosophy would enrich itself by further incorporating this biocultural diversity. On the other hand, environmental philosophy could provide a valuable contribution to biocultural conservation by better articulating the understanding the reticulate diversity of ecological knowledge and practices that indigenous and non-indigenous old-resident communities have co-evolved with particular ecosystems and historic and cultural settings around the world.Finally, furthering the participation of environmental thinkers of different regions and strengthening environmental philosophy networks could contribute to an international dialogue that would generate more pertinent concepts and propositions by more deeply embracing local [End Page 143] social, historical, political, cultural, linguistic, and ecosystem realities. The dynamic diversity of human ecological worldviews and practices has been addressed by the field of environmental philosophy;4 however, this diversity has still not been sufficiently incorporated as part of a multi-discursive community.* * *2. Incorporating environmental philosophy into the theory and praxis of biocultural conservationDuring the last two decades, a main goal of ecological sciences and biological conservation has been a better integration between human and natural systems. Under currently prevailing scientific approaches, such reconnection has been developed primarily through economic valuation of "ecosystem services" (see, for example, the recent landmark Millennium Ecosystem Assessment).5 Environmental philosophy has had a weak presence as compared to ecological economics in the transdiscipline of biological conservation. This weak presence is mismatched with the numerous calls made by ecologists about the need for environmental ethics, and with the frequent reference to ethical values made by international environmental conventions. For instance, the text of the Convention on Biological Diversity begins with a reference to the intrinsic value of biodiversity but it does not develop this notion at all.6 Similarly, the Millennium Ecosystem Assessment mentions the intrinsic value of biodiversity but does not develop the notion, and ends up justifying the need for its conservation in terms of economic values...

Farm-to-school (FTS) programs have garnered the attentions and energies of people in a diverse array of social locations in the food system and are serving as a sort of touchstone for many in the alternative agrifood movement. Yet, unlike other alternative agrifood initiatives, FTS programs intersect directly with the long-established institution of the welfare state, including its vestiges of New Deal farm programs and public entitlement. This paper explores how FTS is navigating the liminal terrain of public and private initiative, (...) particularly the ways in which it interfaces with neoliberalism as both a material and discursive project. It examines the political emergence of school food programs and finds that FTS is strikingly similar to traditional school programs in objectives, but differs in approach. Yet, in their efforts to fill in the gaps created by political and economic neoliberalization, FTS advocates are in essence producing neoliberal forms and practices afresh. These include those associated with contingent labor relationships, private funding sources, and the devolution of responsibility to the local, all of which have serious consequences for social equity. The paper also discusses how FTS programs are employing the rhetoric of neoliberal governmentality, including personal responsibility and individual success, consumerism, and choice. While these may be tactical choices used to secure funding in a competitive environment, they may also contribute to the normalization of neoliberalism, further circumscribing the possibilities of what can be imagined and created to solve social problems.

In lieu of an abstract, here is a brief excerpt of the content:Asian Eels and Global Warming:A Posthumanist Perspective on Society and the EnvironmentAndrew Pickering (bio)My idea in this essay is to talk about how some recent developments in my field—science and technology studies—might pass over into environmental studies. In particular, I want to talk about a certain posthumanist perspective, as I call it, on the relation between people and things, because I think that it transfers nicely from thinking about (...) people and machines to thinking about people and the environment.1 I want to say in advance that while the word 'posthumanist' might sound a bit peculiar, the posthumanist perspective is straightforward enough. If scholars have taken a long time to arrive it, the difficulty lies, I believe, in a disciplinary division of labor rather than in any intrinsic incomprehensibility. And I can start with a few general remarks about that.The basic point to note is that the academic disciplines carve up the visible world in a systematic way. On the one hand, the natural sciences, engineering, and so on, like to talk about a world of things from which people are notably absent. This is clear in fields like physics and chemistry, but it is probably true enough in the environmental sciences, too. Human beings might disturb ecosystems, say, but the job of the ecologist [End Page 29] is to understand the systems themselves, not the disturbances. The social sciences and humanities, in contrast, like to talk about people but not about things. Durkheimian sociology is a great example. Durkheim insisted that the social was a separate reality, sui generis, and that the social therefore has its own pure dynamics, cut off from, say, the material world.We find, then, a beautiful disciplinary dualism: to the harder sciences goes the world of things; to the softer sciences goes the world of people. What about the interface of people and things, the zone of intersection? This is of no concern to the hard sciences: one can easily imagine the world of things going on without people. But what about the soft sciences? One can't really imagine a world of people without things. Here various maneuvers have traditionally served to maintain the humanist purity of disciplines like sociology; I will just mention one. We encounter the material world, it is said, not in its raw state (as studied by physicists or ecologists, say) but as drenched in meaning. The world means something, or many different things, to us. And the point to note is that 'meaning' functions here as a cut-off, a circuit-breaker. Meanings are in our heads and in society; they are not in the material world. So, sociologists can go ahead and study the meanings that people attach to machines or nature without encroaching on the territory of the hard sciences, and the disciplinary division of labor, enshrined in the universities since the 19th century, can live on. The social sciences are about the human meanings of, or attitudes towards, machines, the environment, or whatever; the hard sciences are about things in themselves. That is the basic split that I want to focus on in what follows—actually, to undo it. But I can quickly mention one further twist for the sake of clarity.The basic split between meanings and things-in-themselves is an index of a certain realism—a bow from the soft sciences to the harder sciences, an acknowledgment that the latter somehow gets things right and that what the soft sciences study is a soggy social residue. But some social scientists have refused to bend the knee. They argue that we are all humans, even hard scientists. Therefore we can never get beyond meanings. And therefore we should think of the material world as itself somehow constructed in social practice. The harder sciences find this view absurd, but it is manifest in a split in the social sciences between 'realists' [End Page 30] and 'constructivists'—a split which shows up in many places, including geography and environmental studies. The point I would stress, however, is that the social retains its purity, even in social constructivism—it is simply that there 'the social' expands without limit to encompass... (shrink)

We develop a truism of commonsense psychology that perception and action constitute the boundaries of the mind. We do so however not on the basis of commonsense psychology, but by using the notion of a Markov blanket originally employed to describe the topological properties of causal networks. We employ the Markov blanket formalism to propose precise criteria for demarcating the boundaries of the mind that unlike other rival candidates for “marks of the cognitive” avoids begging the question in the extended (...) mind debate. Our criteria imply that the boundary of the mind is nested and multiscale sometimes extending beyond the individual agent to incorporate items located in the environment. Chalmers has used commonsense psychology to develop what he sees as the most serious challenge to the view that minds sometimes extend into the world. He has argued that perception and action should be thought of as interfaces that separate minds from their surrounding environment. In a series of recent papers Hohwy has defended a similar claim using the Markov blanket formalism. We use the Markov blanket formalism to show how both of their objections to the extended mind fail.
