    1. Skilled Intentionality Framework (SIF) (Rietveld and Kiverstein 2014; Bruineberg and Rietveld 2014; Van Dijk and Rietveld 2017; Rietveld, Denys and van Westen forthcoming), a philosophical, ecological-enactive approach to understand the situated and affective embodied mind.

    1. In both SLA and CALL (computer-assisted language learning) research, a new perspective may be found in ecological approaches, e.g., van Lier (2004), who takes an ecological world view and applies it to language education. Ecology broadly studies organisms in their relations with their environment. Van Lier’s approach thus incorporates many different perspectives with regard to language learning, e.g., sociocultural theory, semiotics, ecological psychology, and the concepts of self and identity. Key constructs in this approach to language learning are affordances and scaffolding, with an affordance defined as the relationship between an organism and something in the environment that can potentially be useful for that organism. Technology is viewed as a source of affordances and learning opportunities for language learners. Appropriate scaffolding, i.e., help from peers, teachers, or technology itself, might also be necessary, and this is a core feature of telecollaboration.

    1. Ecological Approaches to SLA and Technology (Leo van Lier): Ecological approaches to SLA are premised on a holistic view of human-world interrelations and the notion of affordance-effectivity pairings that help to better understand human activity and functioning. To many educators, technology and ecology are irreconcilable opposites. Yet, educationally speaking, they turn out to be perfectly compatible. This presentation examines the ways in which the Internet is an emergent resource, a social tool, and a multimodal repository of texts. The ecological affordances of CALL will be illustrated in terms of activity through, with, at and around computers.

    1. As a threat to the socio-ecological systems to which Nenets have established and depended on throughout history, environmental impact within the region is met with continued opposition and resilience.

      The presence and impact of cultural aspects which facilitate the resilience to changes in the Nenets’ socio-ecological systems is discussed in further detail in the following piece.

    1. Comparison of ITCD algorithms is challenging when there are differences in study focus, study area, data applied, and accuracy assessment method used. Before 2005, the few studies that compared methods generally tested approaches on a common dataset.

      This difficulty in comparing algorithms (due to differences in forest type, location, and assessment strategy used for different algorithms) indicates a clear need for set of open data and centralized assessment to allow different methods to be competed against one another to determine the best routes forward.

      This kind of approach has been very successful in other image analysis problems (e.g., ImageNET).

      The National Ecological Observatory Network data seems ideal for doing something like this. Data is/will be available for a variety of different systems and with LiDAR, Hyperspectral, RGB, and field data for large numbers of plots.

    2. Additionally, it is often challenging to apply an algorithm developed in one forest type to another area.

      This difficulty of applying across forest types is central to the challenges of developing approaches that can be applied to continental scale data collection like that being conducted by NEON. Overcoming this challenge will likely require incorporating ecological information into models, not just the remote sensing, and determining how to choose and adjust different approaches to get the best delineations possible based on information about the forest type/location.

    3. The most useful information that can be incorporated into ITCD studies is the expected crown size and stand density [25,67].

      This kind of data is available for NEON plots and so these methods could potentially be well leveraged with NEON data. This would be particularly true if the NEON plot data could be used to develop a spatial model for these features that could be used to predict their values across space.
