Natural Drift

This chapter demonstrates how unique histories of structural coupling can be understood from the vantage point of evolution. To this end, it provides a critique of the adaptationist view of evolution as a process of progressive fitness, and articulates an alternative view of evolution as natural drift. These unique histories of coupling, which enact incommensurable kinds of “color space,” should not be explained as optimal adaptations to different regularities in the world. Instead, they should be explained as the result of different histories of natural drift. Moreover, since organism and environment cannot be separated but are in fact codetermined in evolution as natural drift, the environmental regularities that one associates with these various color spaces must ultimately be specified in tandem with the perceptually guided activity of the animal.

Main Figure

This chapter introduces the book’s main figure and situates him within the historical moment from which he emerges. It shows the degree to which global geographies shaped the European Catholic mission project. It describes the impact of the Padroado system that divided the world for evangelism between the Spanish and Portuguese crowns in the 15th century. It also argues that European clerics were drawing lines on Asian lands even before colonial regimes were established in the nineteenth century, suggesting that these earlier mapping projects were also extremely significant in shaping the lives of people in Asia. I argue for the value of telling this story from the vantage point of a Vietnamese Catholic, and thus restoring agency to a population often obscured by the lives of European missionaries.

Color Space Transformation

We investigated how well a multilayer neural network could implement the mapping between two trichromatic color spaces, specifically from camera R,G,B to tristimulus X,Y,Z. For training the network, a set of 800,000 synthetic reflectance spectra was generated. For testing the network, a set of 8,714 real reflectance spectra was collated from instrumental measurements on textiles, paints and natural materials. Various network architectures were tested, with both linear and sigmoidal activations. Results show that over 85% of all test samples had color errors of less than 1.0 ΔE2000 units, much more accurate than could be achieved by regression.

The aim of this study was to evaluate the usefulness of the texture and geometric parameters of endocarp (pit) for distinguishing different cultivars of sweet cherries using image analysis. The textures from images converted to color channels and the geometric parameters of the endocarp (pits) of sweet cherry ‘Kordia’, ‘Lapins’, and ‘Büttner’s Red’ were calculated. For the set combining the selected textures from all color channels, the accuracy reached 100% when comparing ‘Kordia’ vs. ‘Lapins’ and ‘Kordia’ vs. ‘Büttner’s Red’ for all classifiers. The pits of ‘Kordia’ and ‘Lapins’, as well as ‘Kordia’ and ‘Büttner’s Red’ were also 100% correctly discriminated for discriminative models built separately for RGB, Lab and XYZ color spaces, G, L and Y color channels and for models combining selected textural and geometric features. For discrimination ‘Lapins’ and ‘Büttner’s Red’ pits, slightly lower accuracies were determined—up to 93% for models built based on textures selected from all color channels, 91% for the RGB color space, 92% for the Lab and XYZ color spaces, 84% for the G and L color channels, 83% for the Y channel, 94% for geometric features, and 96% for combined textural and geometric features.

To accurately extract cultivated land boundaries based on high-resolution remote sensing imagery, an improved watershed segmentation algorithm was proposed herein based on a combination of pre- and post-improvement procedures. Image contrast enhancement was used as the pre-improvement, while the color distance of the Commission Internationale de l´Eclairage (CIE) color space, including the Lab and Luv, was used as the regional similarity measure for region merging as the post-improvement. Furthermore, the area relative error criterion (δA), the pixel quantity error criterion (δP), and the consistency criterion (Khat) were used for evaluating the image segmentation accuracy. The region merging in Red–Green–Blue (RGB) color space was selected to compare the proposed algorithm by extracting cultivated land boundaries. The validation experiments were performed using a subset of Chinese Gaofen-2 (GF-2) remote sensing image with a coverage area of 0.12 km2. The results showed the following: (1) The contrast-enhanced image exhibited an obvious gain in terms of improving the image segmentation effect and time efficiency using the improved algorithm. The time efficiency increased by 10.31%, 60.00%, and 40.28%, respectively, in the RGB, Lab, and Luv color spaces. (2) The optimal segmentation and merging scale parameters in the RGB, Lab, and Luv color spaces were C for minimum areas of 2000, 1900, and 2000, and D for a color difference of 1000, 40, and 40. (3) The algorithm improved the time efficiency of cultivated land boundary extraction in the Lab and Luv color spaces by 35.16% and 29.58%, respectively, compared to the RGB color space. The extraction accuracy was compared to the RGB color space using the δA, δP, and Khat, that were improved by 76.92%, 62.01%, and 16.83%, respectively, in the Lab color space, while they were 55.79%, 49.67%, and 13.42% in the Luv color space. (4) Through the visual comparison, time efficiency, and segmentation accuracy, the comprehensive extraction effect using the proposed algorithm was obviously better than that of RGB color-based space algorithm. The established accuracy evaluation indicators were also proven to be consistent with the visual evaluation. (5) The proposed method has a satisfying transferability by a wider test area with a coverage area of 1 km2. In addition, the proposed method, based on the image contrast enhancement, was to perform the region merging in the CIE color space according to the simulated immersion watershed segmentation results. It is a useful attempt for the watershed segmentation algorithm to extract cultivated land boundaries, which provides a reference for enhancing the watershed algorithm.

1 John

While studies in Johannine ethics continue to develop through analysis of broad ethical instructions, this paper contributes to the conversation by conveying the belief of participatory victory that seems to inform the ethical instruction of the author of 1 John. That is, in the midst of the cosmic conflict in which John and his fellow believers find themselves, John speaks from the vantage point of one who participates in the victory of Jesus to other participants in that victory. Though there is no explicit statement of this notion of participating in the victory of Jesus, its influential place in the authorial framework is discernible at several points in the text, such as when John uses the terminology and imagery of victory, uses the terminology and imagery of participation, and particularly when he converges these two streams of thought.

Abstract This article utilises the methodology of Third Article Theology to explore the church’s missional role in the world. Initially arguing that ecclesiology and missiology are mutually informing doctrines, it develops a dialogical and pneumatological approach for viewing missiology from the vantage point of ecclesiology. This contrasts with and complements the more common approach where missiology is seen as determinative of ecclesiology. The final and major section of the article uses this approach to sketch out the constituent features of the church’s mission, particularly when the Spirit’s role is viewed as primary and constitutive.

Informed and active engagements with works of art make new experimential openings visible as they turn attention to the concreteness of the world. The ordinary and the taken-for-granted must be bracketed out if a poem or a painting or a musical piece is to be achieved. Viewed within the brackets and from an unfamiliar vantage point, reality may become questionable, in need of interpretation, perhaps in need of repair. If learners are provided opportunities for understanding their part in realizing illusioned worlds, they may come to confront their contributions to the construction of their social realities. Teachers who create situations that permit this to happen will be opening up their classrooms, not only to a new sense of the totality, but to a consciousness of what might be, what is not yet. And this, in turn, may provide a ground for common action, for desired change.

The article performs the current discussion of such categories as local and global in modern anthropology and suggests the option of using categories for the modern sociocultural reality of Dagestan society. The positions of leading researchers, deconstructing the concepts of “locality” and “community”, offering an alternative view of a traditional society rooted in a particular place, are demonstrated. Deterritorized societies in the face of significant social changes in the world (migration, including transnational and translocal, as well as the process of globalization) are becoming a new form of social interaction, where physical locality gives way to other categories linking people into relevant communities. In relation to the Dagestan realities, it is proposed to consider local deterritized societies through the prism of the conceptual metaphor “global village”. The factors contributing to the formation of such deterritorialized communities are shown. It is also shown the example of such a community - the village of Bezhta situated on the bordeland with the Republic of Georgia. A look at the complex of physical localities united by belonging to this mountain village (the village itself, resettlement villages on the plain of Dagestan, families located outside the republic in labor migration and living a translocal life, and also to a lesser extent the village of Chantliskuri in Georgia) as version of the "global village".

Shed Light

The world in which we live is crisscrossed by multiple flows of people, information, non-human life, travel circuits and goods. At least since the Sixteenth Century, the Americas have received and generated new social, cultural and product trends. As we see through the case studies presented here, modern literature and dance, the industrialization of food and the race to space cannot be historicized without considering the role the Americas, and particularly the United States, have played in all of them. We also see, at the same time, how these flows of thought, art, science and products emerged from sources outside the Americas to then take root in and beyond the United States. The authors in this special volume are devising conceptual tools to analyze this multiplicity across continents and also at the level of particular nations and localities. Concepts such as cosmopolitanism, translocality and astronoetics are brought to shed light on these complex crossings, giving us new ways to look at the intricacy of these distance-crossing flows. India, perhaps surprisingly, emerges as an important cultural interlocutor, beginning with the idealized, imagined versions of Indian spirituality that fueled the romanticism of the New England Transcendentalists, to the importance of Indian dance pioneers in the world stage during the first part of the twentieth century and the current importance of India as a player in the race to space.
