The notion that eukaryotes are ancestrally sexual has been gaining attention. This idea comes in part from the discovery of sets of “meiosis‐specific genes” in the genomes of protists. The existence of these genes has persuaded many that these organisms may be engaging in sex, even though this has gone undetected. The involvement of sex in protists is supported by the view that asexual reproduction results in the accumulation of mutations that would inevitably result in the decline and extinction of (...) such lineages. It is argued that this phenomenon can be obviated by polyploidy and that the “meiosis‐specific genes” are used in other processes, including polyploidy control and homologous recombination, independent of meiosis. These phenomena account for the finding that these genes are expressed in cultures devoid of apparent cell fusion events. Hence, it is also proposed that asexual, and not sexual, reproduction is the ancestral condition. (shrink)

Daniel Sutherland - Kant on Arithmetic, Algebra, and the Theory of Proportions - Journal of the History of Philosophy 44:4 Journal of the History of Philosophy 44.4 533-558 Muse Search Journals This Journal Contents Kant on Arithmetic, Algebra, and the Theory of Proportions Daniel Sutherland Kant's philosophy of mathematics has both enthralled and exercised philosophers since the appearance of the Critique of Pure Reason. Neither the Critique nor any other work provides a sustained and focused account of his (...) mature views on mathematical cognition, forcing readers to glean what they can from disparate contexts. Despite these hurdles, Kant's views have been of great interest to philosophers of mathematics. They have also been of interest to philosophers wishing to understand Kant's philosophy more generally, since Kant maintains that mathematical judgments are synthetic a priori and that the type of synthesis underlying mathematics is the same as that underlying the perception of objects . Our understanding of Kant's views has been greatly improved during the last four decades by work on Kant's philosophy of mathematics. Despite these advances, however, I think the recent work has largely neglected the importance of Kant's theory of magnitudes and the extent to which that theory is influenced by the Eudoxian theory of proportions presented in Euclid's Elements. As a consequence, an important feature of Kant's.. (shrink)

In this paper we develop a typology of ‘non-commercial’ approaches to farming, based on a survey of a representative sample of farmers in Scotland, United Kingdom. In total, 395 farmers indicated that they do not seek to make a profit on their farms. We estimate that these non-commercial approaches to farming are utilised on at least 13% of agricultural land in Scotland. As such, non-commercial farming is not a marginal practice, nor are NCF limited to small-scale ‘hobby’ farms: NCF exist (...) across the scale of agricultural holding sizes and are operated by a wide range of socio-demographic cohorts. We identify 6 types of NCF: agricultural residences, specialist smallholdings, horsiculture holdings, mixed smallholdings, amenity mixed farms, and large farms or estates. These types were differentiated primarily by the scale of farm size, presence of diversification activities and types of animal present. The analysis demonstrates a number of emergent patterns of land management: de facto land abandonment, transition towards ‘horsiculture’, and management differences between retiring and new entrant NCF. We argue that the types identified reflect a number of intersecting issues in contemporary agrarian transitions, particularly the aging farmer population; generational renewal; and gendered implications of agricultural restructuring.

Amongst the remarkable variety of motility that cells display, cytokinesis (cell division) is particularly striking. Dramatic changes in cell shape occur before, during and after cytokinesis. Myosin II is implicated in the ‘rounding up’ of cells prior to cytokinesis, and is essential in the formation of the contractile cleavage furrow during cytokinesis. Now it appears that myosin II plays a role in all stages of cytokinesis, as a recent report(1) suggests that myosin II drives post‐mitotic cell spreading. A similar type (...) of motile mechanism operating in cell spreading may occur in other cell types in other situations. (shrink)

Most readers will be acquainted with the principal interest of the evolutionary psychologist Nicholas Humphrey via his modestly titled essay 'How to solve the mind-body problem', reprinted in this collection. The article was originally published in JCS , with peer commentary . But, in addition to his popular science books, Humphrey has also written scholarly essays on the more technical aspects of evolutionary theory along with journalistic articles on religion, politics, history, folk psychology and the supernatural. The book under review (...) attempts the difficult task of bringing these differing topics and styles together in one volume. It would be folly to attempt to cover such a broad collection comprehensively, so I will attempt to focus on those aspects most relevant to the aims and scope of this journal.

Understanding Literary Theory is the essential guide for every reader looking to understand what literary theory is and why it matters. This concise and accessible text introduces today's foremost schools of literary theory, offering historical background and outlining the important ideas of each. The theories are then applied to a variety of classic short stories, demonstrating how the different theoretical approaches can yield diverse interpretations of the same literary works. This volume separates itself from similar texts by providing clear and (...) accurate explanations of theory's most challenging concepts. It examines all of the major schools of criticism, including ecocriticism, ethnic studies, feminism, formalism, Marxism, narratology, new historicism, postcolonialism, postmodernism, post-structuralism, psychoanalysis, queer theory, reader response, and structuralism. Each chapter begins with a straightforward summary that outlines the focus of the theoretical approach, its notable practitioners, its advantages and disadvantages, and a concise definition. The chapters then delve into each theory by explaining the key concepts and the ideas that led to them. This book is indispensable for anyone intimidated by words like deconstruction, differance, heteroglossia or hyperreality. Understanding Literary Theory shows readers the interpretative possibilities that literary theory can provide. It is the ideal introduction for those who want to get the most out of the literature they read. (shrink)

A Lagrangian formulation is constructed for particle interpretations of quantum mechanics, a well-known example of such an interpretation being the Bohm model. The advantages of such a description are that the equations for particle motion, field evolution and conservation laws can all be deduced from a single Lagrangian density expression. The formalism presented is Lorentz invariant. This paper follows on from a previous one which was limited to the single-particle case. The present paper treats the more general case of many (...) particles in an entangled state. It is found that describing more than one particle while maintaining a relativistic description requires the specification of final boundary conditions as well as the usual initial ones, with the experimenter’s controllable choice of the final conditions thereby exerting a backwards-in-time influence. This retrocausality then allows an important theoretical step forward to be made, namely that it becomes possible to dispense with the usual, many-dimensional description in configuration space and instead revert to a description in space–time using separate, single-particle wavefunctions.

The aggregate EIRP of an N-element antenna array is proportional to N 2. This observation illustrates an effective approach for providing deep space networks with very powerful uplinks. The increased aggregate EIRP can be employed in a number of ways, including improved emergency communications, reaching farther into deep space, increased uplink data rates, and the flexibility of simultaneously providing more than one uplink beam with the array. Furthermore, potential for cost savings also exists since the array can be formed using (...) small apertures. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Stewart R. Sutherland LANGUAGE AND INTERPRETATION IN CRIME AND PUNISHMENT OF some novels it is possible to argue with justification that the problems of interpretation and understanding begin on the first page. Of Dostoyevsky's Crime and Punishment it is possible to contend that the problems of interpretation and understanding begin on the title page. The terms "crime" and "punishment" are overtly moral. The novel is read in the (...) context of a title which exhibits its values where they may be seen by all. What significance must we attach to the choice of such a title? It is possible that the title gives to us a characterization of the content of the novel which, retrospectively, we can only regard as either self-consciously ironical, or perhaps pathetically so, but how are we to decide whether this is more than a possibility? Having raised this question, I propose to set it aside in the hope of returning to it equipped with the experience derived from a number of literary and philosophical digressions. The literary and conceptual style of critical comment upon a novel often betrays much that is definitive of the response being elucidated. If one compares and contrasts Philip Rahv's essay on Crime and Punishment with the appropriate chapter of Mochulsky's Dostoevsky,2 the implication of this general claim may be clarified. My intention here is to use largely ostensive means to suggest the radically different accounts of the novel given to us by these two writers. That the conclusions are different is hardly in need of statement. What is worth examining is the character of the language and of the arguments used to substantiate those conclusions. The point of my discussion will rest not upon assessing the accuracy or legitimacy of particular judgments, but rather upon delineating the general contours of the intellectual contexts in which these judgments are offered. 223 224Philosophy and Literature Rahv's focus is on the character or psyche of Raskolnikov. The novel is seen largely in the form of a psychological study of the mind of the murderer. He reminds us that a central problem for Raskolnikov, for the reader, and for Dostoyevsky himself, is the identification of Raskolnikov's motive—not that there is an absence of motives, indeed quite the reverse: "He is soon lost in the maze of his own motivation" (p. 20). His mind spins incessantly upon an axis the nature of which is nowhere made unambiguously apparent. Nor, it seems, can we replace our search for a motive, or the sufficient reason for action, by identifying a supreme assertion of will: again, on the contrary, we are told, "Dostoyevsky is the first novelist to have fully accepted and dramatized the principle of uncertainty or indeterminacy in the presentation of character" (p. 21). Despite that, however, the success of the novel rests upon Dostoyevsky's skills in allying the insight "... that human consciousness is inexhaustible and incalculable" (p. 19), to "his capacity to combine [seeming contradictions] in a single brain and a single psyche, while staving off the danger of incoherence at one end and of the specious reconciliation at the other..." (p. 38). The mood ofRahv's treatment of the novel is dominated in this way by the language of (largely popularized) psychology—"pathological depression," "nameless guilt-feelings," "wishful fantasy"—and not surprisingly, he sees his own preoccupations as mirroring those of Dostoyevsky: "What Dostoyevsky has done in revising Raskolnikov's justification is to convert into a theory of human nature what is in Hegel not a psychological theory at all but a theory of men as subjects and objects of history" (p. 34). Mochulsky, on the other hand, breathes a very different atmosphere. From the outset he talks of "the spiritual existence of Dostoyevsky's heroes," and he says of a man who wills a murder or one who "betrays himself to the powers of dark necessity" (pp. 302-303), "The murderer has stepped beyond something more than the moral law: the very basis ofthe spiritual worlditself" (p. 303). "The whole tragedy of man-godhood," he tells us, "is expressed in these few words: 'It seems to me,' Raskolnikov says, 'truly great people experience an immense... (shrink)

Kant's Critique of Pure Reason makes important claims about space, time and mathematics in both the Transcendental Aesthetic and the Axioms of Intuition, claims that appear to overlap in some ways and contradict in others. Various interpretations have been offered to resolve these tensions; I argue for an interpretation that accords the Axioms of Intuition a more important role in explaining mathematical cognition than it is usually given. Appreciation for this larger role reveals that magnitudes are central to Kant's philosophy (...) of mathematics and to the part that intuition plays in it. (shrink)

The focus here is on analytical and instrumental requirements for those collective decision exercises that lend themselves to a judgment-driven resolution. These have not as yet received much concerted technical attention from either of the two main movements in the field. They remain somewhere beyond the purview of the objectively-predicated instruments that mainstream GDSS (Group Decision Support System) designs tend to favour. Yet neither are they so inherently ill-structured as the situations with which the GDNSS (Group Decision and Negotiation Support (...) System) community is concerned, these usually allowing only a subjectively-predicated, compromisive or consensus-based conclusion. If the technical requirements peculiar to judgment-driven decision exercises are to be well met, it will be through the offices of analytical instruments that can help assure the rationality of the resolutions at which they arrive. The primary purpose of these pages is to offer some suggestions about the types of analytical instruments that might serve this end. (shrink)

The rapid development of machine-learning algorithms, which underpin contemporary artificial intelligence systems, has created new opportunities for the automation of work processes and management functions. While algorithmic management has been observed primarily within the platform-mediated gig economy, its transformative reach and consequences are also spreading to more standard work settings. Exploring algorithmic management as a sociotechnical concept, which reflects both technological infrastructures and organizational choices, we discuss how algorithmic management may influence existing power and social structures within organizations. We identify (...) three key issues. First, we explore how algorithmic management shapes pre-existing power dynamics between workers and managers. Second, we discuss how algorithmic management demands new roles and competencies while also fostering oppositional attitudes toward algorithms. Third, we explain how algorithmic management impacts knowledge and information exchange within an organization, unpacking the concept of opacity on both a technical and organizational level. We conclude by situating this piece in broader discussions on the future of work, accountability, and identifying future research steps. (shrink)

Recent decades have seen a rapid increase in the rate of conversion from conventional to organic farming, as organic farming shifted from an alternative production approach practiced by a small number of idealists, to the de facto alternative to mainstream conventional production. Although there has been considerable academic debate as to the role of agri-business penetration into the production and marketing chains of organic farming (‘conventionalization’), less is known about how the economic drivers of conventionalization are negotiated into practices at (...) the farm level. Drawing on Bourdieu’s conceptualization of economic and cultural capitals, the direct connection between symbols of ‘good farming’ and the economic requirements of maintaining a viable farming business (i.e., the ‘taste of necessity’) is demonstrated. Findings indicate that conventional and organic farmers in the study sites identified a similar range of cultural symbols, but organic farmers emphasized different symbols within this range. This diversity and selectivity demonstrates the fragmentation and contestation of ideals resulting from economic challenges at the time of the study. Economic capital is important to the decision to consider conversion to organic farming, but formal conversion reflects re-weighting of forms of cultural capital. The author argues that recognition of the impact of economic pressures on conventional farming, which in the study sites often led to reduced input use rather than intensification, is missing from the conventionalization debate. The mainstreaming of organic farming production has presented conventional farmers with a set of alternative or re-weighted symbols and a crucible for reflexive consideration of their own standards and practices of farming.

It is common for social theorists to utilize the metaphors of ‘flow’, ‘fluidity’, and ‘liquidity’ in order to substantiate the ways in which speed and mobility form the basis for a new kind of information or network society. Yet rarely have these concepts been sufficiently theorized in order to establish their relevance or appropriateness. This article contends that the notion of flow as utilized in social theory is profoundly metaphysical in nature, and needs to be judged as such. Beginning with (...) a discussion of the accelerating timescape that characterizes the network society, it will then move on to examine three main issues with this ‘metaphysics of flux’. First, that the concept of flows unjustly privileges the process of becoming and, as a result, is unable to account for the materiality, substantiality, and agency of the objects being mobilized, and the contingency of their mediation. Second, that it posits the accelerating tendencies of capital as an ontological inevitability, thus discounting resistance to such forces. Finally, that it ignores the human faculty for reason and speculative thought in developing alternative means of political praxis. The solution, it will be argued, is not to abandon metaphysical accounts of the network society, but rather to challenge those accounts that, in exhibiting a crude empiricism, work to justify the status quo.

It was, I believe, Thomas Arnold who wrote: ‘Educate men without religion and all you make of them is clever devils’. Thus the Headmaster of one famous school summarized pithily the view of the relationship between religion and ethics which informed educational theory and practice in this country for at least a further century. There is a confusion of two different assumptions usually to be found in this context. The first is that religious belief can provide an intellectual foundation for (...) moral belief; the second is that the effect of religious teaching is to improve behaviour according to the norms of some particular set of moral beliefs.

It is of course true that the articulation of religious and theological views depends upon and often masks philosophical presuppositions. For example, those who quote with approval Anselm's ‘credo ut intelligam’, ‘I believe so that I may understand’, seldom follow the good example set by Anselm, and make explicit, as Anselm does in the following sentence, the fact that this principle rests upon a further principle: ‘For I believe this also, that “unless I believe, I shall not understand”’ . This (...) paper is an attempt to track down and expose one very pervasive set of views about the nature of experience which is implicit in a wide range of religious and theological claims. (shrink)

In the last ten years or so there has been some lively discussion of the questions of immortality and resurrection. Within the Christian tradition there has been debate at theological and exegetical level over the relative merits of belief in the immortality of the soul, and belief in the resurrection of the dead as an account of life after death. Further to this, however, there has been the suggestion that there may be good philosophical reasons for preferring the latter to (...) the former. It is just this contention which I propose to discuss. (shrink)
