Architects are constantly moving toward something that does not as yet exist.37 The reality of the building comes after the fact of a plan. At one level the plan and the reality are obviously unalike; yet at another level the relationship between these must be a literal one. In the process of building, some elements are kept constant, while others transform out of all recognition. Radical shifts in scale and material substance take place, as proportions and forms are exactly preserved....

AbstractOver the past decades, cultural heritage has increasingly become a primary target of terrorist destruction. As such attacks not only hit the cultural objects themselves, but also people and societies inherently associated with them, this article calls for a shift of emphasis in protection of cultural property from mere material substance protection to the relationship between humans and cultural objects. To this end, the present work rethinks cultural heritage as a hybrid entity between legal object and legal person, i. e., as material agency. The article takes a critical view of the traditional juridical distinction between legal object (res) and legal person (persona), and of material and immaterial cultural heritage. By taking full advantage of the legal potential of these four aspects, and reflecting on the recent ruling of the International Criminal Court in The Hague regarding the terrorist destruction of Timbuktu, the article provides a springboard toward an anthropological transformation of the protection of cultural property.

Martin Luther’s doctrine of creation can be identified as the center of his theology. The justification for this judgement is threefold. First, the centrality of creation to Luther’s theology is rooted in Luther’s expansive interpretation of the act of creation. Luther’s theology of creation is neither limited to a description of what happened “in the beginning” nor restricted to some initial and selective point of life. Instead, Luther understands creation as the principal and permanent feature of God’s action and communication, something happening constantly and taking place in a threefold way: by creation, preservation, and re-creation. In addition to this Martin Luther’s doctrine of creation is a strong antidote against any present Deism or present Gnosticism. Second, creation may be seen as central to Luther’s theology because it describes God’s sovereignty and is directly linked to it. For Luther, God’s action is always sola gratia, always a creatio ex nihilo. This does not mean that Luther ignores or denies the vast creational involvement in creatural matters, for instance, in the emergence of new life. Instead, his intention is to emphasize God’s almightiness: God acts purely out of freedom and love and not because of any obligation. When God creates, he needs no available material substance, when God justifies, he needs no preliminary human work. Of course, God may use them but he does not need them. In principle, God’s actions are all initial and initiating beginnings. Therefore, creation, preservation, and re-creation happen “without any of my merit and worthiness.” Every calculating do ut des—I give to you so that you give to me—comes to an end here. All creatural and theological creation, preservation, and re-creation is not earned by one’s own virtue but given sola gratia. Third, the doctrine of creation is central because Luther develops out of it the basis of his ethical thinking. God’s already described creational activity puts all humankind into place and determines their role in creation. Luther understands the human’s response to God’s gift to lie in the gratitude of the creature toward the creator, and not in the critique of the creator or in a tempting or attempting “improvement” of the gift through an effort of self-creation. As creature, one is called to shape the given world, but more so to receive one’s own personal destiny with gratitude. For Luther, this thankfulness also means embracing, or at least accepting, one’s own creation as a destiny that is determined, individual, and in many respects unalterable. In addition to this personal perspective of gratitude, God’s verbal and communicative means of creation in dialogue with his creature is for Luther a basic feature of his ethics as well. Luther generalizes this creational dialogical structure and uses it in the ethical field not only to characterize the relationship between creator and creature but also to characterize the relationships among the creatures themselves.

A review is given of information on the galactic-centre region obtained from recent observations of the 21-cm line from neutral hydrogen, the 18-cm group of OH lines, a hydrogen recombination line at 6 cm wavelength, and the continuum emission from ionized hydrogen.Both inward and outward motions are important in this region, in addition to rotation. Several types of observation indicate the presence of material in features inclined to the galactic plane. The relationship between the H and OH concentrations is not yet clear, but a rough picture of the central region can be proposed.

The Mesozoic-Cenozoic coral Order Scleractinia has been suggested to have originated or evolved (1) by direct descent from the Paleozoic Order Rugosa or (2) by the development of a skeleton in members of one of the anemone groups that probably have existed throughout Phanerozoic time. In spite of much work on the subject, advocates of the direct descent hypothesis have failed to find convincing evidence of this relationship. Critical points are:(1) Rugosan septal insertion is serial; Scleractinian insertion is cyclic; no intermediate stages have been demonstrated. Apparent intermediates are Scleractinia having bilateral cyclic insertion or teratological Rugosa.(2) There is convincing evidence that the skeletons of many Rugosa were calcitic and none are known to be or to have been aragonitic. In contrast, the skeletons of all living Scleractinia are aragonitic and there is evidence that fossil Scleractinia were aragonitic also. The mineralogic difference is almost certainly due to intrinsic biologic factors.(3) No early Triassic corals of either group are known. This fact is not compelling (by itself) but is important in connection with points 1 and 2, because, given direct descent, both changes took place during this only stage in the history of the two groups in which there are no known corals.

Abstract This commentary focuses upon the relationship between two themes in the target article: the ways in which a Markov blanket may be defined and the role of precision and salience in mediating the interactions between what is internal and external to a system. These each rest upon the different perspectives we might take while “choosing” a Markov blanket.

Abstract Cognitive Gadgets offers a new, convincing perspective on the origins of our distinctive cognitive faculties, coupled with a clear, innovative research program. Although we broadly endorse Heyes’ ideas, we raise some concerns about her characterisation of evolutionary psychology and the relationship between biology and culture, before discussing the potential fruits of examining cognitive gadgets through the lens of active inference.

It is well known that a large flux of electrons must pass through a specimen in order to obtain a high resolution image while a smaller particle flux is satisfactory for a low resolution image. The minimum particle flux that is required depends upon the contrast in the image and the signal-to-noise (S/N) ratio at which the data are considered acceptable. For a given S/N associated with statistical fluxtuations, the relationship between contrast and “counting statistics” is s131_eqn1, where C = contrast; r2 is the area of a picture element corresponding to the resolution, r; N is the number of electrons incident per unit area of the specimen; f is the fraction of electrons that contribute to formation of the image, relative to the total number of electrons incident upon the object.

Echinodermata is a phylum of marine invertebrates which has been extant since Cambrian time (c.a. 500 m.y. before the present). Modern examples of echinoderms include sea urchins, sea stars, and sea lilies (crinoids). The endoskeletons of echinoderms are composed of plates or ossicles (Fig. 1) which are with few exceptions, porous, single crystals of high-magnesian calcite. Despite their single crystal nature, fracture surfaces do not exhibit the near-perfect {10.4} cleavage characteristic of inorganic calcite. This paradoxical mix of biogenic and inorganic features has prompted much recent work on echinoderm skeletal crystallography. Furthermore, fossil echinoderm hard parts comprise a volumetrically significant portion of some marine limestones sequences. The ultrastructural and microchemical characterization of modern skeletal material should lend insight into: 1). The nature of the biogenic processes involved, for example, the relationship of Mg heterogeneity to morphological and structural features in modern echinoderm material, and 2). The nature of the diagenetic changes undergone by their ancient, fossilized counterparts. In this study, high resolution TEM (HRTEM), high voltage TEM (HVTEM), and STEM microanalysis are used to characterize tha ultrastructural and microchemical composition of skeletal elements of the modern crinoid Neocrinus blakei.

The in vitro human tumor cloning assay originally described by Salmon and Hamburger has been applied recently to the investigation of differential anti-tumor drug sensitivities over a broad range of human neoplasms. A major problem in the acceptance of this technique has been the question of the relationship between the cultured cells and the original patient tumor, i.e., whether the colonies that develop derive from the neoplasm or from some other cell type within the initial cell population. A study of the ultrastructural morphology of the cultured cells vs. patient tumor has therefore been undertaken to resolve this question. Direct correlation was assured by division of a common tumor mass at surgical resection, one biopsy being fixed for TEM studies, the second being rapidly transported to the laboratory for culture.

Three techniques were incorporated for drying clay-rich specimens: air-drying, freeze-drying and critical point drying. In air-drying, the specimens were set out for several days to dry or were placed in an oven (80°F) for several hours. The freeze-dried specimens were frozen by immersion in liquid nitrogen or in isopentane at near liquid nitrogen temperature and then were immediately placed in the freeze-dry vacuum chamber. The critical point specimens were molded in agar immediately after sampling. When the agar had set up the dehydration series, water-alcohol-amyl acetate-CO2 was carried out. The objectives were to compare the fabric plasmas (clays and precipitates), fabricskeletons (quartz grains) and the relationship between them for each drying technique. The three drying methods are not only applicable to the study of treated soils, but can be incorporated into all SEM clay soil studies.
