The Evolution of Giving: Considerations for Regulation of Cryptocurrency Donation Deductions

This Issue Brief looks at the rapidly growing area of cryptocurrency donations to nonprofit organizations. Given the recent IRS guidance issued on taxation of Bitcoin, specifically its decision to treat cryptocurrencies as property, questions now arise as to how charitable contributions of the coins will be valued for tax deductions. Though Bitcoin resembles most other capital gain property, its volatility, general decline in value, anonymity, and potential for abuse require specific guidance on valuation and substantiation so as to handle its unique nature and prevent larger deductions for charitable contributions than those to which taxpayers are entitled

TV 2.0: animation readership / authorship on the internet

Traditional platforms for animation, such as broadcast television or cinema, are rapidly becoming obsolete as a new type of spectator demands more choice, the ability to interact with animated content and access to global distribution for their own user-generated work. Audiences are no longer satisfied with receiving a top down distribution of content from traditional cinema or broadcasters. Internet technologies are emerging to address this demand for active spectatorship and enable communities of interest to evolve their own alternative distribution methods. Viewing animation online has become increasingly accessible with the mass adoption of broadband and the emergence of new file formats. TV 2.0 is an amalgamation of Internet technologies that combine video on demand with the social networking capabilities of Web 2.0. In the age of TV 2.0, the role of the viewer has increased in complexity with new possibilities for active interaction and intervention with the content displayed. This new audience seeks a form of spectatorship that can extend beyond the passive recipience of programming distributed by elite broadcasters. TV 2.0 on the Internet has changed both methods of distribution and traditional patterns for the viewing of animation. However, any potential for democratic participation in the visual culture of moving images that this could entail may be a brief historic moment before the assimilation and control of active readership by mainstream corporate culture

Animation Installation: the Affect of Place

Goosebumps, hairs stand on end, a knot in the stomach, an inexplicable feeling of chill or even panic...walking through an unfamiliar place can have a visceral impact on the human subject. This artist’s presentation will consider the experience of viewing animation within the context of a site-specific installation and, through reference to examples of exhibitions by Birgitta Hosea in which contemporary animations are displayed as an intervention in historic spaces, will investigate the affect of site and the impact of the viewing context on the embodied perception of an animation

Colour for behavioural success

Colour information not only helps sustain the survival of animal species by guiding sexual selection and foraging behaviour but also is an important factor in the cultural and technological development of our own species. This is illustrated by examples from the visual arts and from state-of-the-art imaging technology, where the strategic use of colour has become a powerful tool for guiding the planning and execution of interventional procedures. The functional role of colour information in terms of its potential benefits to behavioural success across the species is addressed in the introduction here to clarify why colour perception may have evolved to generate behavioural success. It is argued that evolutionary and environmental pressures influence not only colour trait production in the different species but also their ability to process and exploit colour information for goal-specific purposes. We then leap straight to the human primate with insight from current research on the facilitating role of colour cues on performance training with precision technology for image-guided surgical planning and intervention. It is shown that local colour cues in two-dimensional images generated by a surgical fisheye camera help individuals become more precise rapidly across a limited number of trial sets in simulator training for specific manual gestures with a tool. This facilitating effect of a local colour cue on performance evolution in a video-controlled simulator (pick-and-place) task can be explained in terms of colour-based figure-ground segregation facilitating attention to local image parts when more than two layers of subjective surface depth are present, as in all natural and surgical images

Seven properties of self-organization in the human brain

The principle of self-organization has acquired a fundamental significance in the newly emerging field of computational philosophy. Self-organizing systems have been described in various domains in science and philosophy including physics, neuroscience, biology and medicine, ecology, and sociology. While system architecture and their general purpose may depend on domain-specific concepts and definitions, there are (at least) seven key properties of self-organization clearly identified in brain systems: 1) modular connectivity, 2) unsupervised learning, 3) adaptive ability, 4) functional resiliency, 5) functional plasticity, 6) from-local-to-global functional organization, and 7) dynamic system growth. These are defined here in the light of insight from neurobiology, cognitive neuroscience and Adaptive Resonance Theory (ART), and physics to show that self-organization achieves stability and functional plasticity while minimizing structural system complexity. A specific example informed by empirical research is discussed to illustrate how modularity, adaptive learning, and dynamic network growth enable stable yet plastic somatosensory representation for human grip force control. Implications for the design of “strong” artificial intelligence in robotics are brought forward

Various measures to achieve the EU goal for the use of bioenergy with special focus on field energy. Challenges for agricultural policy

The growing interest in biomass and energy produced from this is mainly considered a positive thing in terms of current agricultural production. Increased use of renewable resources as biomass gives a good opportunity to agriculture to promote its positive environmental functions and to make its contribution to the work to prevent climate change

Spatial Facilitation by Color and Luminance Edges: Boundary, Surface, and Attentional Factors

The thresholds of human observers detecting line targets improve significantly when the targets are presented in a spatial context of collinear inducing stimuli. This phenomenon is referred to as 'spatial facilitation', and may reflect the output of long-range interactions between cortical feature detectors. Spatial facilitation has thus far been observed with luminance-defined, achromatic stimuli on achromatic backgrounds. This study compares spatial facilitation with line targets and collinear, edge-like inducers defined by luminance contrast to spatial facilitation with targets and inducers defined by color contrast. The results of a first experiment show that achromatic inducers facilitate the detection of achromatic targets on gray and colored backgrounds, but not the detection of chromatic targets. Chromatic inducers facilitate the detection of chromatic targets on gray and colored backgrounds, but not the detection of achromatic targets. Chromatic spatial facilitation appears to be strongest when inducers and background are isoluminant. The results of a second experiment show that spatial facilitation with chromatic targets and inducers requires a longer exposure duration of the inducers than spatial facilitation with achromatic targets and inducers, which is already fully effective at an inducer exposure of 30 milliseconds only. The findings point towards two separate mechanisms for spatial facilitation with collinear form stimuli: one that operates in the domain of luminance, and one that operates in the domain of color contrast. These results are consistent with neural models of boundary and surface formation which suggest that achromatic and chromatic visual cues are represented on different cortical surface representations that are capable of selectively attracting attention. Multiple copies of these achromatic and chromatic surface representations exist corresponding to different ranges of perceived depth from an observer, and each can attract attention to itself. Color and contrast differences between inducing and test stimuli, and transient responses to inducing stimuli, can cause attention to shift across these surface representations in ways that sometimes enhance and sometimes interfere with target detection.Defense Advanced Research Projects Agency and Office of Naval Research (N00014-95-1-0409, N00014-95-1-0657
