This in-depth case study examines the Russian Orthodox Church's influence on federal-level policy in the Russian Federation since the fall of communism. By far more comprehensive than competing works, The Orthodox Church and Russian Politics is based on interviews, close readings of documents--including official state and ecclesiastical publications--and survey work conducted by the author.
In this paper we propose an ‘undisciplinary’ meeting between Elinor Ostrom and Judith Butler, with the intent to broaden the theory of the commons by discussing it as a relational politics. We use Butler’s theory of power to problematize existing visions of commons, shifting from Ostrom’s ‘bounded rationality’ to Butler’s concepts of ‘bounded selves’ and mutual vulnerability. To be bounded – as opposed to autonomous being – implies being an effect of socio-power relations and norms that are often beyond control. (...) Thus, to be a collective of bounded selves implies being mutually vulnerable in power relations which are enabling, albeit injurious. A politics of commoning is not a mere technical management of resources but a struggle to perform common livable relations. We argue that the multiple exposures which produce us are also the conditions of possibility for more just and equalitarian ‘re-commoning’ of democracies around the world. (shrink)
A widespread assumption in experimental comparative cognition is that, barring compelling evidence to the contrary, the default hypothesis should postulate the simplest cognitive ontology consistent with the animal’s behavior. I call this assumption the principle of cognitive simplicity . In this essay, I show that PoCS is pervasive but unjustified: a blanket preference for the simplest cognitive ontology is not justified by any of the available arguments. Moreover, without a clear sense of how cognitive ontologies are to be carved up (...) at the joints—and which tools are appropriate for the job—PoCS rests on shaky conceptual ground. (shrink)
Behavioural flexibility is often treated as the gold standard of evidence for more sophisticated or complex forms of animal cognition, such as planning, metacognition and mindreading. However, the evidential link between behavioural flexibility and complex cognition has not been explicitly or systematically defended. Such a defence is particularly pressing because observed flexible behaviours can frequently be explained by putatively simpler cognitive mechanisms. This leaves complex cognition hypotheses open to ‘deflationary’ challenges that are accorded greater evidential weight precisely because they offer (...) putatively simpler explanations of equal explanatory power. This paper challenges the blanket preference for simpler explanations, and shows that once this preference is dispensed with, and the full spectrum of evidence—including evolutionary, ecological and phylogenetic data—is accorded its proper weight, an argument in support of the prevailing assumption that behavioural flexibility can serve as evidence for complex cognitive mechanisms may begin to take shape. An adaptive model of cognitive-behavioural evolution is proposed, according to which the existence of convergent trait–environment clusters in phylogenetically disparate lineages may serve as evidence for the same trait–environment clusters in other lineages. This, in turn, could permit inferences of cognitive complexity in cases of experimental underdetermination, thereby placing the common view that behavioural flexibility can serve as evidence for complex cognition on firmer grounds.

This book reorients the question of the matrix as a place "where" everything comes from ( "chora," womb, incubator) by recasting it in terms of acts of "matrixial/maternal hospitality" that produce space and matter of / for the other.
Based on a dual process view of ethical judgment, we examine the role of empathic concern and perspective taking on the acceptability of lying to protect the company. We hypothesize that these traits will matter to a different extent under conditions of high and low perceived time hurriedness. Our research hypotheses are tested in a survey of 134 US workers. Results show that empathic concern reduces the acceptability of lying to protect the company for individuals who tend to do things (...) quickly and feel in a hurry at work. On the other hand, perspective taking reduces the acceptability of lying for individuals who experience low levels of time hurriedness. Theoretical and practical implications of the findings are discussed. (shrink)
In this article I attempt to conceptualize myexistential and institutional experience as thedirector of the Kharkov Center for GenderStudies acquired in the course of introducinggender studies into the system of post-Soviethigher education. The main subject of thearticle concerns the logical ground of genderdiscourse and the complicated relations betweenthe notions of `gender studies', `women'sstudies', and, within the latter, `feminism' inthe former USSR, all in the framework ofconcepts from Western feminists theory.
In guarding against inferential mistakes, experimental comparative cognition errs on the side of underattributing sophisticated cognition to animals, or what I refer to as the underattribution bias. I propose eliminating this bias by altering the method of choosing the default, or null, hypothesis. Rather than choosing the most parsimonious null hypothesis, as is current practice, I argue for choosing the best-evidenced hypothesis. Doing so at once preserves the risk-controlling structure of the current statistical paradigm and introduces a sensitivity to probability-conferring (...) empirical and theoretical information. This analysis illustrates how values like parsimony can covertly shape statistical-experimental design and inference. (shrink)
This paper investigates the role of pictures in mathematics in the particular case of Cayley graphs—the graphic representations of groups. I shall argue that their principal function in that theory—to provide insight into the abstract structure of groups—is performed employing their visual aspect. I suggest that the application of a visual graph theory in the purely non-visual theory of groups resulted in a new effective approach in which pictures have an essential role. Cayley graphs were initially developed as exact mathematical (...) constructions. Therefore, they are legitimate components of the theory (combinatorial and geometric group theory) and the pictures of Cayley graphs are a part of practical mathematical procedures. (shrink)
We suggest that understanding unethical behavior in organizations involves understanding how people view themselves and their relationships with others, a concept known as self-construal. Across multiple studies, employing both field and laboratory settings, we examine the impact of three dimensions of self-construal (independent, relational, and collective) on unethical behavior. Our results show that higher levels of relational self-construal relate negatively to unethical behavior. We also find that differences in levels of relational self for men and women mediate gender differences in (...) unethical behavior. We discuss both the theoretical and practical implications of these findings. (shrink)
The tectonic history of the Gulf of Mexico is a subject for ongoing debate. The nature of the crust in the northwestern and central parts of the basin remains poorly understood. Joined interpretation of two 2D seismic cross sections — GUMBO1 and GUMBO2 — with potential fields constrained with available well data allows testing various hypotheses about the subsurface structures and crustal architecture in the study area. In the northwestern GOM, two contradicting hypotheses about the nature of the crust were (...) tested — exhumed mantle versus a thinned and intruded continental crust resulted from magma-rich rifting. The nature of the crust was also investigated in the central GOM, where the disagreement in the location of the ocean-continent boundary from various published tectonic models reaches 140 km. The results suggest that the crust in the study area is stretched continental with multiple magmatic additions represented by dense and highly magnetic bodies with fast seismic velocities, presumably introduced during the magma-assisted rifting of the GOM. The contact between oceanic and continental domains, i.e., the OCB, is interpreted to be near the Sigsbee Escarpment for both modeled lines. The analysis does not support the presence of thick presalt sediments in the study area. This result questions the currently accepted tectonic reconstructions of the GOM as thick presalt deposits are imaged confidently by various seismic surveys along the western Yucatan margin, which is believed to be a conjugate for the study area. This apparent mismatch in distribution of the presalt sediments requires further investigation. (shrink)
A 3D gravity model was developed in the western Gulf of Mexico in the East Breaks and Alaminos Canyon protraction areas. This model integrated 3D seismic, gravity, and well data; it was constructed in support of a proprietary seismic reprocessing project and was updated iteratively with seismic. The gravity model was built from seismic horizons of the bathymetry, salt layers, and the acoustic basement; however, the latter was only possible to map in seismic data during the latest iterations. In addition, (...) a deep layer representing the Moho boundary was derived from gravity and constrained by public-domain refraction data. A 3D density distribution was derived from the seismic velocity volume using a modified Gardner equation. The modification comprised imposing a depth dependency on the Gardner coefficient, which is constant in the classic Gardner equation. The modified coefficient was derived from well data in the study area and public-domain velocity-density data sets. The forward-calculated gravity response of the composed density model was then compared with the observed gravity field, and the mismatch was analyzed jointly by a seismic interpreter and a gravity modeler. Adjustments were then made to the gravity model to ensure that the resultant salt model was geologically reasonable and supported by gravity, seismic, and well data sets. The output of the gravity modeling was subsequently applied to the next phase of seismic processing. Overall, this integration resulted in a more robust salt model, which has led to significant improvements in subsalt seismic imaging. The analysis of the regional trend in the observed gravity field suggested that a stretched continental crust underlay our seismic reprocessing area, with an oceanic-continental transition zone located to the southeast of our reprocessing region.

This article engages the concept of hospitality as it relates to the maternal. I critically evaluate the current conceptions of hospitality by Emmanuel Levinas and Jacques Derrida, focusing on their dematerialized definition of the feminine found at the heart of hospitality, and Derrida's aporia of hospitality that deals with ownership. The foundation of hospitality, I show, is the maternal relation and its specific acts of hospitality that encompass the notions of gift and generosity. While remaining unthought in philosophy, however, maternal (...) acts of hospitality are appropriated when hospitality is defined as interiority, habitation, expectancy, and unconditional welcoming of the other within oneself. I argue that hospitality would remain Derrida's and his proponents' “impossible” ethic as long as it undercuts its own promise, does not fully think through its foundation in the maternal, and fails to welcome the mother unconditionally.

The question of whether object recognition is orientation-invariant or orientation-dependent was investigated using a repetition blindness (RB) paradigm. In RB, the second occurrence of a repeated stimulus is less likely to be reported, compared to the occurrence of a different stimulus, if it occurs within a short time of the first presentation. This failure is usually interpreted as a difficulty in assigning two separate episodic tokens to the same visual type. Thus, RB can provide useful information about which representations are (...) treated as the same by the visual system. Two experiments tested whether RB occurs for repeated objects that were either in identical orientations, or differed by 30, 60, 90, or 180°. Significant RB was found for all orientation differences, consistent with the existence of orientation-invariant object representations. However, under some circumstances, RB was reduced or even eliminated when the repeated object was rotated by 180°, suggesting easier individuation of the repeated objects in this case. A third experiment confirmed that the upside-down orientation is processed more easily than other rotated orientations. The results indicate that, although object identity can be determined independently of orientation, orientation plays an important role in establishing distinct episodic representations of a repeated object, thus enabling one to report them as separate events.

Traditional accounts of the fair play principle suggest that, under appropriate conditions, those who benefit from the cooperative labor of others acquire an obligation of repayment. However, these accounts have had little to say about the nature of such obligations within morally or legally problematic cooperative schemes, taking the matter to be either straightforward or unimportant. It is neither. The question of what sorts of fair play obligations obtain for those who benefit from illicit cooperative activity is a matter of (...) great complexity and consequence with implications for, inter alia, global economic justice. In this essay, I explore the nature of this obligation within illicit cooperative schemes, specifically those with so-called negative externalities, or deleterious effects on non-members of the scheme. I conclude that the willing beneficiaries of such schemes acquire a fair-play obligation to recognize and respond to their culpability. This reconceptualization of the fair play principle opens up new avenues for exploring the obligations of those who benefit from acts of collective wrongdoing. (shrink)
In her seminal attack on modern moral philosophy, G. E. M. Anscombe claims that Kant's ‘rule about universalizable maxims is useless without stipulations as to what shall count as a relevant description of an action with a view to constructing a maxim about it’. Although this so-called problem of relevant descriptions has received considerable attention in the literature, there is little agreement on how it should be understood or solved. My aim in this paper is, first, to clarify the problem (...) by clearing up several misunderstandings, and, second, to show that the problem is rooted in a standard assumption about Kant's stance on the scope of moral principles—an assumption that precludes its solution. I argue that the problem consists in the fact that Kant's formula of universal law seems to stand in need of an account of moral sensibility that does not render the formula superfluous. But, as my discussion of existing solutions reveals, there can be no such account. Instead, I propose a dissolution: we should think of the formula of universal law itself as Kant's account of moral sensibility. In order to do so, we must reject the standard assumption that a principle is universal if and only if it holds for all instances of the action type that it specifies. (shrink)
Parallels between cancer and ecological systems have been increasingly recognized and extensively reviewed. However, a more unified framework of understanding cancer as an evolving dynamical system that undergoes a sequence of interconnected changes over time, from a dormant microtumor to disseminated metastatic disease, still needs to be developed. Here, we focus on several examples of such mechanisms, namely, how in cancer niche construction a metabolic adaptation and consequent change to the tumor microenvironment becomes an important factor in evasion of the (...) predator, facilitating disease progression; how tumor establishment and propagation is driven by the tumor’s own keystone species, the cancer stem cells; and how the succession of stages of metastatic dissemination can be informed by ergodic theory and forest ecology.

The paper aims to show how mathematical practice, in particular with visual representations, can lead to new mathematical results. The argument is based on a case study from a relatively recent and promising mathematical subject—geometric group theory. The paper discusses how the representation of groups by Cayley graphs made possible to discover new geometric properties of groups.
Behandlungsfehler in der Psychotherapie sind bisher kaum erforscht. Eine empirisch gestützte Kategorisierung von Behandlungsfehlern stellt einen ersten Schritt dar, sich evidenzbasierten ethischen Empfehlungen zum Umgang mit solchen Fehlern zu nähern. Zielsetzung dieser Arbeit ist es, dafür erste Grundlagen zu erarbeiten, die auf Erfahrungen von Praktikern Bezug nehmen. Nach einer systematischen Literaturrecherche wurden 30 semistrukturierte Interviews mit approbierten Psychotherapeuten unterschiedlicher Ausrichtungen (Schulen) geführt und anhand der qualitativen Inhaltsanalyse nach Mayring ausgewertet. Die beschriebenen, alltäglich auftretenden Behandlungsfehler konnten in technische, normative, Einschätzungs- und (...) Systemfehler klassifiziert werden. Viele der technischen und Einschätzungsfehler wurden als reversibel angesehen; sie könnten sogar konstruktiv für die Behandlung nutzbar gemacht werden. Das Versäumnis, einen Fehler zu korrigieren, wurde als Hauptfehler betrachtet. Bei normativen Fehlern sei mit rechtlichen oder berufspolitischen Konsequenzen, aber auch mit Vertrauensverlust und Therapieabbruch zu rechnen. Für Systemfehler fühlten sich die befragten Therapeuten nicht verantwortlich; hier seien berufspolitische Änderungen nötig. Die Ergebnisse zeigen, dass die Befragten zu der Empfehlung tendieren, Psychotherapiepatienten in passender Form über Behandlungsfehler aufzuklären und in die entstehenden Konsequenzen einzubeziehen. Fazit: Psychotherapeuten äußern sich aufgeschlossen gegenüber einer transparenten, konstruktiven Fehlerkultur – eine wesentliche Voraussetzung für Fehlerprävention. Häufig resultiert erst durch die fehlende Korrektur eines (alltäglichen) Fehlers ein Behandlungsfehler, der Konsequenzen hat (z. B. Scheitern der Therapie). Um diesem entgegenzuwirken, zeichnet sich eine Befürwortung für eine passende Form der Patientenaufklärung über Fehler ab. (shrink)
We analyze programs for undergraduate women in science and engineering as strategic research sites in the study of disparities between women and men in scientific fields within higher education. Based on responses to a survey of the directors of the universe of these programs in the United States, the findings reveal key patterns in the programs’ definitions of the issues of women in science and engineering, their solutions to address the issues, their goals and perceived success with goals, and their (...) organizational characteristics and relationship to the larger institutional environments. The findings—which are conceptually grounded in the distinction between structural/institutional and individual issues facing women in science—have implications for understanding gender, science, and higher education, and for initiatives undertaken to improve the condition of women in scientific fields. The findings may also inform strategic efforts to reduce gender disparity in other organizational contexts. (shrink)
In this chapter, the author examines how the simplicity heuristic adversely affects a relatively new tool in experimental comparative cognition: cognitive models. It does so, she argues, by directing intellectual resources into the development and refinement of putatively simple cognitive models at the expense of putatively more complex ones, which in turn directs experimenters to develop tests to rule out these simple models.
In this paper we study the problem of a possibility to use quantum observables to describe a possible combination of the order effect with sequential reproducibility for quantum measurements. By the order effect we mean a dependence of probability distributions on the order of measurements. We consider two types of the sequential reproducibility: adjacent reproducibility ) and separated reproducibility). The first one is reproducibility with probability 1 of a result of measurement of some observable A measured twice, one A measurement (...) after the other. The second one, \, is reproducibility with probability 1 of a result of A measurement when another quantum observable B is measured between two A’s. Heuristically, it is clear that the second type of reproducibility is complementary to the order effect. We show that, surprisingly, this may not be the case. The order effect can coexist with a separated reproducibility as well as adjacent reproducibility for both observables A and B. However, the additional constraint in the form of separated reproducibility of the \ type makes this coexistence impossible. The problem under consideration was motivated by attempts to apply the quantum formalism outside of physics, especially, in cognitive psychology and psychophysics. However, it is also important for foundations of quantum physics as a part of the problem about the structure of sequential quantum measurements. (shrink)

Dealing with errors in psychotherapy is challenging, both ethically and practically. There is almost no empirical research on this topic. We aimed (1) to explore psychotherapists’ self-reported ways of dealing with an error made by themselves or by colleagues, and (2) to reconstruct their reasoning according to the two principle-based ethical approaches that are dominant in the ethics discourse of psychotherapy, Beauchamp & Childress (B&C) and Lindsay et al. (L).
Addressing the critique that communication activities with regard to CSR are often merely instrumental marketing or public relation tools, this paper develops a toolbox of CSR communication that takes into account a deliberative notion. We derive this toolbox classification from the political approach of CSR that is based on Habermasian discourse ethics and show that it has a communicative core. Therefore, we embed CSR communication within political CSR theory and extend it by Habermasian communication theory, particularly the four validity claims (...) of communication. Given this communicative basis, we localize CSR communication as a main means to receive moral legitimacy within political CSR theory. A typology of CSR communication tools is advanced and substantiated by a review of case studies supporting the categories. Thus, we differentiate between instrumental and deliberative, as well as published and unpublished tools. Practical examples for the literature-derived tool categories are provided and their limitations are discussed. (shrink)
The article defines the structure, level and structure of expenditures of the State Budget of Ukraine for economic activity. We found a number of budget support priority sectors, including the energy sector, roads, agriculture and so on. The source for the analysis is the application of the Law of Ukraine "On State Budget of Ukraine for 2014" and the program code and functional classification of expenditures and financing of the budget. The law provides for implementation in 2014 of more than (...) 500 budget programs, of which the largest budgetary allocations provided for key spending units. Analyzed the proportion of spending on economic activity in the State Budget of Ukraine, which only zamaye twentieth share in the general fund, and almost a third in a special fund, which indicates a clear thrust of expenditure. The author notes that a significant amount of funds allocated to the coal industry subsidies and restructuring at the expense of the general fund of the State Budget of Ukraine is economically justified to ensure the economic security of Ukraine. The main part of a special fund aimed at financing for road infrastructure as infrastructural spheres of the national economy, the responsibility for proper condition which carries state. Established that priority areas for financing agriculture in general and special funds of the State Budget of Ukraine is the state support for the development of domestic livestock food market as well as the costs of participation in international specialized organizations to ensure adequate state control over the standards and quality of food products extremely important in terms of Ukraine's accession to the WTO and the EU to strengthen the competitiveness of domestic producers. Positively also characterize the structure of fiscal expenditures on economic activity, a significant proportion of the fund and the special fund. However insufficient volume and specific gravity is funding fundamental and applied research in various fields of national economy, which hinders its innovative development. (shrink)
This essay examines the unique conception of self (atman) developed by Utpaladeva, one of the greatest philosophers of the Kashmir Saiva Recognition (Pratyabhijña) school, in polemics with Buddhist no-self theorists and rival Hindu schools. The central question that fueled philosophical debate between Hinduism and Buddhism for centuries is whether a continuous stable entity, which is either consciousness itself or serves as the ground of consciousness, is required to sustain all the experienced features of embodied physical and mental activity, and, in (...) the context of the conceptualization of the world as saṃsara, whether such a self persists between rebirths and in liberation. Utpaladeva argues contra Buddhists and contra other atmavadins not only that differentiation and unity or change and continuity are compatible, but that a coherent account of our experience requires a continuous dynamic substratum that accommodates both. The Pratyabhijña's atman is opposed to that of Nyaya, Vaiseṣika, and Mimaṣs;a insofar as it is de-individuated, which makes it close to Advaita's Brahman, also a universal consciousness, from which it differs, however, insofar as it is theological and acts as the contentbearer by taking on forms, as opposed to being impersonal and passive. When compared with theologies, both from within and outside the wider domain of Hindu thought, the Pratyabhijña proves to be unique in that it gives a philosophically nuanced account of God, who stands in a nondual relationship to the individual self. This essay also compares the Pratyabhijña's theological account of self with the theological idealism of Berkeley and Bradley, finding it closer to the latter. Comparing the Pratyabhijña with its nearest Western philosophical counterparts should make it more accessible and intelligible from the standpoint of the Western academy and pave the way for involving its rich and distinctive conception of self in the fledgling cross-cultural philosophical dialogue on questions concerning self and consciousness.

Снятие идеологического пресса советской идеологии не привело к спонтанному возрождению в России традиций политической мысли. Однако заметны признаки появления новой школы политической философии, обретающей свою идентичность в диалоге с родственными дисциплинами . В этом можно видеть поворот к феноменологической философии, хотя гуссерлевский, по сути, интерес к феноменам сознания преобразуется здесь в изучение морали как «процесса». Отнесение политической морали к сфере компетенции консеквенциальной этики задает поле новой теории с новыми понятиями . Все это показано на примере работ Б.Г.Капустина. La disparition de (...) la pression idéologique soviétique n’a pas suffi pour que renaissent en Russie de façon spontanée les traditions de pensée politique. Mais on peut entrevoir des signes avant-coureurs d’une nouvelle école de philosophie politique qui se forge une identité en dialoguant avec les disciplines apparentées . C’est là un virage en philosophie phénoménologique, même si, à l’intérêt husserlien pour les phénomènes de conscience , se substitue l’étude des « processus » de la morale. Le transfert de la morale politique vers la sphère de compétence de l’éthique conséquentielle dessine le champ d’une nouvelle théorie où l’on trouve de nouvelles notions . Tout cela est bien illustré par l’œuvre de Kapoustine. The disappearance of Soviet ideological pressure was not enough for a Russian rebirth of spontaneous traditions of political thought. But we can feel signs of the appearance of a new school of political philosophy that builds its identity through a dialogue with cognate disciplines . One might regard this transformation as a tum towards a phenomenological approach, though Husserl’s interest in the phenomena of consciousness is replaced here by the study of the “process” of morality. The transfer of political morality towards the jurisdiction of consequential ethics creates a new theory which relies on new concepts . All this is weil illustrated by the work of Kapustin. (shrink)
This article explores the kinds of response John Dewey received in Russia between 1900 and 1930, and the impact he had on the educational debate there. The study’s main findings are: Both before and after the Socialist October Revolution of 1917, Dewey had a significant impact on the development of the Russian school system. The ultimate rejection of Dewey’s pedagogy towards the end of the 20s was not due to educational but to political and ideological reasons.
This paper concerns the role of intuitions in mathematics, where intuitions are meant in the Kantian sense, i.e. the “seeing” of mathematical ideas by means of pictures, diagrams, thought experiments, etc.. The main problem discussed here is whether Platonistic argumentation, according to which some pictures can be considered as proofs (or parts of proofs) of some mathematical facts, is convincing and consistent. As a starting point, I discuss James Robert Brown’s recent book Philosophy of Mathematics, in particular, his primarily examples (...) and analogies. I then consider some alternatives and counterarguments, namely John Norton’s opposite view, that intuitions are just pictorially represented logical arguments and are superfluous; and the Kantian transcendental theory of construction in imagination, as it is developed in the works of Marcus Giaquinto and Michael Friedman. Although I support the claim that some intuitions are essential in mathematical justification, I argue that a Platonistic approach to intuitions is partial and one should go further than a Platonist in explaining how some intuitions can deliver new mathematical knowledge.

We have investigated the crustal structure of a 400 km wide zone of thinned continental crust in the northeastern Gulf of Mexico using gravity and magnetic modeling along two deeply penetrated seismic transects. Using this approach, we identify two zones of prominent, southward-dipping reflectors associated with 7–10 km thick, dense, and highly magnetic material. Previous workers have interpreted the zones as either coarse clastic redbeds of Mesozoic age that are tilted within half-grabens or seaward-dipping reflectors of magmatic origin. Both seismic (...) reflection lines reveal a 10 km thick and 67 km wide northern zone of high density near the Florida coastline beneath the Apalachicola rift. The southern zone of high density occurs 70 km to the south in the deepwater central GOM along the northern flank of the marginal rift, a 48 km wide, southeast-trending structure of inferred Late Jurassic age that is filled by 3 km of low-density and low-magnetic susceptibility sediments including complexly deformed salt deposits. We propose that these two subparallel rifts and their associated magmatic belts formed in the following sequence: AR formed during Triassic-early Jurassic phase 1 of diffuse continental stretching and was partially infilled on its northern edge by southward-dipping volcanic flows; and the similarly southward-dipping southern magmatic zone formed adjacent to the marginal rift during the early phase 2 of late Jurassic rifting of the GOM continental extension; this southern area of SDR formation immediately preceded the formation of the adjacent oceanic crust that separated the rift-related evaporates into the northern and southern GOM. Our integrated approach combining 2D seismic, gravity, and magnetic data sets results in a more confident delineation of these deep crustal features than from seismic data alone. (shrink)
