We study uncertainty relations for a general class of canonically conjugate observables. It is known that such variables can be approached within a limiting procedure of the Pegg–Barnett type. We show that uncertainty relations for conjugate observables in terms of generalized entropies can be obtained on the base of genuine finite-dimensional consideration. Due to the Riesz theorem, there exists an inequality between norm-like functionals of two probability distributions in finite dimensions. Using a limiting procedure of the Pegg–Barnett type, (...) we take the infinite-dimensional limit right for this inequality. Hence, uncertainty relations are derived in terms of generalized entropies. In particular, the case of measurements with a finite precision is addressed. It takes into account that in any experiment an accuracy of performed measurements is always limited. (shrink)

This paper argues that a liberal state is justified in promoting relationships of conjugal love – the form of relationship that is the basis of the institution of marriage – on the grounds that they are essential to the development and maintenance of autonomy. A deep human need is that the detail of our lives be recognized (accepted, affirmed, granted importance) by others (or by an other). Autonomy can be compromised when this need is not met. So a state (...) concerned with autonomy ought to be concerned with relationships in which people can be given recognition. This argument justifies support for friendship as well as conjugal love; why is the latter particularly special? The answer is that in conjugal love partners value each other exclusively (i.e., in a way they do not value anyone else). Conjugal relations therefore recognise the uniqueness and individual value of a person's life in away that friendship does not. (shrink)

This article is concerned with thinking transformations of the secular, and does so in relation to two theoretical terrains, while empirically grounded in ethnographies of Christian and Islamic pious women in the Netherlands. A first theoretical terrain under consideration is that of how the relation between modernity and religion is elaborated, notably in secularization theories, and how these established frameworks are challenged by a different kind of articulation between modernity and religion that I observed in narratives and practices of young (...) Evangelical and Islamic women in the Netherlands. The article traces the contours of a `pious modern', showing how from a faith-centred perspective the modern can be incorporated and indeed produced. In this context, I argue that the way in which notions of modernization and secularization have been theoretically hinged on each other needs to be further revisited, and I propose to consider the `post-secular' as a new disarticulation between the modern and the secular. A second theoretical terrain concerns questions of agency and subjectivity. Here I trace how situating religious agency in its own grammar makes secular assumptions in social, critical and feminist theory visible, and generates different understandings not only of agency but also of notions such as autonomy, and the capacity to act and shape the world.

In my response to Golash I distinguish between two steps in my original argument. The first relates to the special value of conjugal (two-person) love relationships. I defend this step against criticisms, arguing that the two-person relationship provides a form of recognition that is of special importance to us and cannot be found in other sorts of relationship. The two-person relationship is one that, at least as private individuals, we have special reason to pursue. The second step concerns the (...) claim that the special value of such relationships tends to promote the autonomy of those who have them. It is this second step that is important for the argument that a liberal state – one, at any rate, that takes itself to be in the business of safeguarding the pre-conditions of autonomy – could have reason to favour marriage or some form of civic partnership over other forms of intimate adult tie. However, I admit that Golash puts forward plausible – if anecdotal – arguments against this second step. I therefore agree that I need to be more tentative about this step than I was in the original paper. (shrink)

We study an expansion of the Distributive Non-associative Lambek Calculus with conjugates of the Lambek product operator and residuals of those conjugates. The resulting logic is well-motivated, under-investigated and difficult to tackle. We prove completeness for some of its fragments and establish that it is decidable. Completeness of the logic is an open problem; some difficulties with applying the usual proof method are discussed.

In the traditional form of canonical quantization, certain field components (not having “conjugate” momenta) must be regarded as noncanonical. This long-known distinction enters modern gauge theories, when they are canonically quantized as by Kugo and Ojima. We avoid that peculiarity by not using any conjugate “momenta” at all. In our formulation, canonical quantization can be related to Feynman's path integral.

This article deploys and extends Ulrich Beck’s critique of ‘zombie categories’ :261–277, 2001) to consider how conjugal relationships are brought into being before the law. The argument presented here is that sexual performatives relating to marriage—and especially, in this instance, consummation—continue to produce a kind of social-legal magic, even as the social flesh of their enactment is rotting. Rules concerning annulment relating to wedding ceremonies, consent, disclosure, and consummation demonstrate that certain frameworks of conjugality involve a kind of corporeal (...) magic animating the privileged place of heterosexual marriage. Thus, rules and regulations pertaining to weddings continue to produce and protect heterogendered, sexually dimorphous bodies, even though this privileging is—or at least, is becoming—socially obsolete.

Quels enjeux sont à l’œuvre dans les situations de recomposition familiale lorsqu’elles sont conflictuelles? Dans ce texte, nous postulons qu’on ne peut saisir quelque chose de la parentalité en dehors de la conjugalité, que ce soit lorsque le couple est séparé ou lors de la création d’un nouveau couple. Nous pensons que conjugalité et parentalité étant intrinsèquement liées, leur liaison doit être remaniée lors de séparation et/ou de recomposition. Nous tentons de montrer que dans certaines situations conflictuelles il y a (...) un déplacement des affects de la relation conjugale sur la relation parentale. (shrink)

Pour cet article de réflexion critique, il s’agit de montrer en quoi les sites de rencontre, en proposant un dispositif spécifique de mise en relation de possibles partenaires, contribuent à modifier à différents niveaux la façon de concevoir le couple et de réfléchir à ce qu’il représente. L’intellectualisation que représente la nécessité de présentation de soi avant même l’éventuelle rencontre, tout autant que la définition des attentes envers le possible partenaire, positionnent différemment l’individu par rapport à une rencontre « classique (...) ». Les dimensions plus concrètes, physiques, et aussi inconscientes en jeu dans une rencontre « spontanée » semblent passer au second plan, au moins dans un premier temps. Mais ce processus de rationalisation porte en lui un certain nombre de contradictions, qui peuvent entrer en phase avec les paradoxes de l’hypermodernité : réalisation de soi dans l’autre et exacerbation des attentes envers autrui en parallèle avec l’affirmation individualiste de soi….

This article examines how gender shapes the migration and settlement experiences of Mexican immigrant women and men. The article compares the experiences of families in which the husbands departed prior to 1965 to those in which the husbands departed after 1965 and argues that the lengthy spousal separations altered patterns of patriarchal authority and the traditional gendered household division of labor. This induced a trend toward more egalitarian conjugal relations upon settlement in the United States. Examining the changing (...) contexts of migration illuminates the fluid character of patriarchy's control in Mexican immigrant families. (shrink)

We consider a quadratic Lagrangian, in both curvature and torsion, with the aim of exploring the possibility that torsion and curvature behave as conjugate variables satisfying the commutation relations. For that proposal we first show that torsion represents a quantum correction to the classical equations of motion. We then observe that we have to introduce the spin in the Einstein theory with two spaces: a real space-time where we describe the curvature with tensors; and a complex space-time, where we (...) describe torsion with spinors. This is not satisfactory, and to overcome this contradiction we describe both mass and spin in a unique manifold, the real space-time, with the use of geometric algebra and geometric product. In that manner we are able to introduce a torsion trivector and curvature trivector that satisfy the commutation relations, opening the road for a quantum description of gravity theory. (shrink)

Dans les pays occidentaux, de nombreux nouveaux parents se sentent seuls et parfois impuissants avec leur nouveau-né. Ce sentiment peut être lié à un défaut d’étayage familial dans l’immédiat post-partum. Cet article présente, à partir d’une recherche universitaire plus large, un cas clinique approfondi dans lequel la distance familiale et géographique a été un facteur de vulnérabilité majeur. Ce cas montre les incidences multiples et intriquées d’un défaut d’étayage familial sur les processus intrapsychiques et intersubjectifs : dépression du post-partum chez (...) la mère qui persiste dans le temps, relations conjugales et parentales qui se dégradent progressivement, et sur les interactions précoces difficiles. Révéler l’existence de ce risque améliorera la compréhension des besoins des parents et des bébés après la naissance et permettrait d’envisager une adaptation plus fine des pratiques professionnelles et des programmes de santé publique et, à plus grande échelle, des politiques familiales.

L’entrée de l’ordinateur cristallise les relations latentes à la vie de couple et les contradictions qui la minent. Pour comprendre ces effets, encore faut-il connaître le devenir de la vie conjugale. En effet, un objet technique n’a de sens que dans la mesure où il s’inscrit dans un corps social traversé par ses propres dynamiques. L’ordinateur accentue donc, plutôt qu’il ne crée, certains traits d’évolution de la famille et des rapports homme/femme. Il intervient dans un univers déjà investi par (...) un ensemble d’objets techniques socialement marqués et inégalement répartis entre les sexes.The introduction of the computer uncovers the dormant relations in a couple’s life and its undermining contradictions. To apprehend this phenomenon, a thorough knowledge of today’s domestic life is essential. Indeed, a technical object only makes sense insofar as it integrates into a society with its own underlying dynamics. The computer, as a consequence, does not produce, but rather emphasizes some trends of the evolution of both family and current gender relations. It enters into an arena already surrounded with technical objects that are socially marked and unevenly distributed among the sexes. (shrink)

Pendant la Grande Guerre, les millions de lettres échangées entre les soldats mobilisés et leurs conjointes permettent d’observer les rapports conjugaux qui se recomposent, se nouent ou se dénouent alors. Elles constituent des sources précieuses pour étudier la place des émotions dans la fabrication de nouvelles relations à distance. Cet article interroge le genre des émotions déployées dans les relations conjugales à distance, et suit trois objectifs : questionner la façon dont s’expriment et se décrivent, en commun ou (...) différemment, les émotions masculines et féminines ; mesurer de quelle façon le conflit, épreuve sentimentale pour les couples séparés, trouble l’expression des émotions ou les réinvente ; comprendre enfin de quelle façon les émotions – exprimées ou tues dans l’interaction épistolaire – jouent un rôle dans le ré-assignement des rôles sexués imposés dès le début du conflit.

Intervenant depuis 1987 dans un Point Rencontre AFCCC à Bordeaux puis à Pau (structures appelées officiellement aujourd’hui Espaces Rencontre pour le Maintien des Relations Enfants-Parents), mais également psychothérapeute psychanalytique de couple et médiateur familial, l’auteur tente, par la confrontation de ces approches cliniques différentes, d’éclairer d’un regard nouveau la question du conflit conjugal qui, pour lui aujourd’hui, n’est plus la cause de ces situations de crise et de ruptures extrêmes mais l’expression du symptôme d’une problématique relationnelle entre parent (...) et enfant. De même, partant de son approche psychanalytique du couple et de la famille, il insiste ici sur le fait que ces différentes démarches (thérapie, médiation et Espace rencontre) ne s’adressent pas aux mêmes personnes ou tout du moins pas au même stade de leur crise et sur la nécessité d’en cerner le mieux possible les limites dans leurs champs d’action respectifs. Enfin, interpellé sur la question des relations entre parent et enfants placés, il décrit comment ces situations spécifiques sont abordées dans les Espaces Rencontre. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Sexual Symmetry: Love in the Ancient Novel and Related GenresAndrew WalkerDavid Konstan. Sexual Symmetry: Love in the Ancient Novel and Related Genres. Princeton: Princeton University Press, 1994. xiii + 270 pp. Cloth, $35.“Thus there begins to develop an erotics different from the one that had taken its starting point in the love of boys.... This new erotics organizes itself around the symmetrical and reciprocal relationship of a man (...) and a woman, around the high value attributed to virginity, and around the complete union in which it finds perfection.” So Michel Foucault asserts in a concluding chapter of his three-volume History of Sexuality (III, The Care of the Self [1984, trans. 1986] 232), a history that began as an effort to describe the emergence of sexuality as the subject of a distinct science in the late nineteenth century (I, An Introduction [1976, trans. 1978]) and that later broadened into “a genealogy of desiring man, from classical antiquity through the first centuries of Christianity” (II, The Use of Pleasure [1984, trans. 1985] 12). Here Foucault is commenting on the transition from pederasty to heterosexual love as the subjects of philosophical reflection on the nature of desire and its proper management. It is to this “new erotics” of heterosexual reciprocity that David Konstan’s title Sexual Symmetry refers: the notion that a new construction of sexuality emerged in the Common Era, a sexuality structured, not hierarchically as in the relationship between the erasts and the ermenos (with its predatory dynamic of subject and object, active and passive partners), but symmetrically, with an emphasis on the subjectivity of both partners who, although of opposite sex, are alike in age, social standing, and measure of amatory attachment, culminating in the Christian ideal of conjugal love and heterosexual fidelity. Konstan’s subtitle, Love in the Ancient Novel and Related Genres, provides an index to the book’s focus on literary genres and to Konstan’s generic approach to his subject matter, first locating the ideal of erotic reciprocity in the five Greek romances that survive (chaps. 1 and 2) and then showing how this type of relationship differs markedly from the representation of desire in the (roughly contemporaneous) Latin novels of Petronius and Apuleius (chap. 3), as well as in a wide variety of related literary genres that antedate the novel and contributed to its emergence as a literary form (chap. 4). In none of these, Konstan argues, do we find the type of erotic reciprocity enjoyed by the hero and heroine of the standard Greek romance. In later chapters, Konstan contrasts further still this idea of erotic reciprocity, as represented in the ancient texts, with the representation of desire in modern fiction (from Sidney’s Arcadia and Richardson’s Pamela to the contemporary Harlequin Romance, chap. 5), and he attempts (however briefly) to identify those aspects of the social milieu that might account for the emergence and appeal of “sexual symmetry” in Greek fiction (chap. 6).Konstan’s argument is summarized in his introduction, and the progression of each chapter is aided by subheadings which are listed in the table of contents. All Greek is transliterated, and all foreign-language texts, including modern [End Page 165] scholarship, are translated to make the work accessible for the nonspecialist. A single index collects words, themes, topics, and authors—both ancient and modern—discussed. The list of works cited runs for nearly thirty pages and contains more than seven hundred items. The book is suitable for comparativists curious about the antecedents of modern romance, and especially useful for classicists who desire a synoptic view of gender studies in the context of classical literature and culture. Few scholars, I suspect, will complete this book without encountering something new in the way of ancient text or modern scholarship—a fact which in itself is testimony to the impressive breadth of Konstan’s own reading and depth of his erudition.This is not to say that the work is without problems of its own, both of a technical nature and of a theoretical sort. For one thing, Konstan’s argument by its very nature demands a large measure of plot summary of the detailed... (shrink)

Bacterial conjugation, wherein DNA is transferred between cells through direct contact, is highly prevalent in complex microbial communities and is responsible for spreading myriad genes related to human and environmental health. Despite their importance, much remains unknown regarding the mechanisms driving the spread and persistence of these plasmids in situ. Studies have demonstrated that transferring, acquiring, and maintaining a plasmid imposes a significant metabolic burden on the host. Simultaneously, emerging evidence suggests that the presence of a conjugative plasmid can also (...) provide both obvious and unexpected benefits to their host and local community. Combined, this highlights a continuous cost‐benefit tradeoff at the population level, likely contributing to overall plasmid abundance and long‐term persistence. Yet, while the metabolic burdens of plasmid conjugation, and their causes, are widely studied, their attendant potential advantages are less clear. Here, we summarize current perspectives on conjugative plasmids’ metabolic burden and then highlight the lesser‐appreciated yet critical benefits that plasmid‐mediated metabolic burdens may provide. We argue that this largely unexplored tradeoff is critical to both a fundamental theory of microbial populations and engineering applications and therefore warrants further detailed study. (shrink)

This paper investigates the campaign waged by Islamic scholars affiliating to the Shādhiliyya-Jazūliyya Sufi order among tribal people in the mountain region of Northern Morocco in the sixteenth century. It examines these scholars’ campaign against bidʿa in the mountains, focusing on their attacks against traditional practices related to marriage and conjugal life that they considered religiously and morally aberrant. The primary source discussed here is a guidebook for marriage, titled Etiquette of Husband and Wife, containing diverse legal doctrines, fatwās, (...) anecdotes, and other accounts. Based on this document, we examine these scholars’ ideological background, the methods they used, and the kinds of practices they censured. They intended to enhance strict sexual segregation by using sufi masters’ religious authority and dhikr to conquer the resistance of the tribal people who had allowed men and women to mix each other publicly. They also demanded a hierarchical structure of religious education, with the family as the base for the Islamization of juridical norms in tribal society. This paper shows that the people did not strictly follow the scholars’ dictates because these restrictions were incompatible with their way of life in this region. It is probable that the leaders of the campaign afforded to the cause of the Saʿdids because they expected that their activity would proceed better under a new regime with more effective governance and control over society.

Uncertainty relations and complementarity of canonically conjugate position and momentum observables in quantum theory are discussed with respect to some general coupling properties of a function and its Fourier transform.

In particular, it is argued that the Heisenberg interpretation of the uncertainty relations can consistently be carried through (...) in a natural extension of the usual Hilbert space frame of the quantum theory.

This paper examines the contents and institutional context of August Weismann's long essay on Amphimixis (1891). Therein he presented detailed discussions of his on-going studies of reduction division and parthenogenesis, but more to the point, he included an elaborate examination of Émile Maupas's two major publications in protozoology. To understand the relevance of this part to the other two, the author briefly reviews highpoints in earlier nineteenth century protozoology and concludes that only in the mid-1870s and 1880s did protozoa add (...) an important dimension to heredity theory. Otto Bütschli and then Maupas provided Weismann with a deeper understanding of how conjugation and fertilization were related but not identical processes. This allowed him to integrate the two into a fuller understanding of evolution by natural selection. (shrink)

The evolutionary origin of human pair-bonds is uncertain. One hypothesis, supported by data from forgers, suggests that pair-bonds function to provision mothers and dependent offspring during lactation. Similarly, public health data from large-scale industrial societies indicate that single mothers tend to wean their children earlier than do women living with a mate. Here we examine relations between pair-bond stability, alloparenting, and cross-cultural trends in breastfeeding using data from 58 “traditional” societies in the Standard Cross-Cultural Sample (SCCS). Analyses show that (...) stable conjugal relationships were associated with significantly later weaning among the societies in the SCCS. The relationship between pair-bond stability and age at weaning was not mediated by women’s ability to provision themselves or women’s kin support. Availability of alloparental care was also inversely related to age at weaning, and the association was not significantly reduced after controlling for frequency of divorce. This study indicates that among a woman’s kin relationships, a pair-bond with a child’s father is especially supportive of breastfeeding. These cross-cultural findings are further evidence that human pair-bonds may have evolved to support lactation. (shrink)

Les historiens qui se sont intéressés à la sexualité au xviie siècle ont souvent noté qu’il était rare d’accéder à une parole féminine.

It is demonstrated that the Heisenberg uncertainty relation is not universal and explained why this is so. A universal uncertainty relation (...) for canonically conjugate coordinates and momenta is suggested. (shrink)

While self-interest is depreciated in Confucian ethics the processes of family relations in traditional China are animated by the self-interested actions of family members. The paper outlines the Confucian ideology of filial piety which is commensurate with the governance of family life organized hierarchically and through the senior male's management of the joint-family's collective property. The structure, operations and principles of membership in traditional Chinese families are indicated, highlighting the tensions within them between consanguinity and conjugality and their material (...) bases. The differential operation of self-interested actions by husbands and wives is also presented. A non-Confucian model of the relational-self is outlined in which both the collective context of Chinese families and the self-interested actions of individual family members within them is explicated.

General regularities related toLagrangian andHamiltonian equations are revealed. Probability distributions for functions ofHamiltonian random variables are considered. It is shown that all probability distributions of this kind are fully determined by the probability distributions for the random variables satisfying the corresponding Lagrangian equations. Some formulas related tocanonically conjugate operators are given. The similarity of these formulas to those related to Hamiltonian random variables is demonstrated. The “quantum approach” to the treatment of Hamiltonian random variables is discussed, and the origin of (...) some peculiarities related to this approach is elucidated; it is explained, in particular, why it is impossible to form the joint probability density for canonically conjugate random variables when using this approach. The peculiarities revealed prove to be common for any objects possessing Hamiltonian random variables, irrespective of the nature of the objects, and coincide, therefore, with those in quantum mechanics. The existence of joint probability distributions for canonically conjugate random variables in the general case is demonstrated through the calculation of the corresponding joint mathematical expectations in an illustrative example. This proves, in particular, that joint probability distributions for canonically conjugate coordinates and momenta exist indeed in the case of mechanical microsystems. The results obtained prove once again that the pecularities of quantum mechanics are not related to the specificity of the measurements of physical quantities for microsystems. (shrink)

This article presents a theoretical framework that views interpersonal power as interdependent with broader structures of gender and class inequalities. In contrast to oversimplified, gender-neutral or gender-static approaches, this approach illuminates the ways that structures of inequality are expressed in ideological hegemonies, which enhance, legitimate, and mystify the interpersonal power of privileged men relative to lower-status men and women in general. The discussion centers on how the relational construction of ascendant and subordinated masculinities provide men with different modes of interpersonal (...) power that, when exercised, construct and reaffirm interclass male dominance. Examples of how the construction of femininity can undermine women's interpersonal power and implications for other forms of masculinities and femininities are discussed. Examples are drawn from an analysis of conjugal power in the accounts of remarried individuals' first and second marriages to illustrate the main points of this perspective. (shrink)

L’amour conjugal existe au Moyen Âge, la littérature en est un lieu d’expression privilégié.

If the brain has a level of quantum functioning that permits superposition of possibilities and nonlocal control of states, then new answers to the problem of the consciousness/brain relation become available.

In the framework developed each person can properly state: ‘I am nonlocal control and my meanings are control variables.’ Cognition is identified with a conjugate reality and perception is (...) where quantum cognition, quantum memory and the quantum re-presentation of quantum reality meet and make a conjugate match.

We review the relation between spacetime geometries with trace-torsion fields, the so-called Riemann–Cartan–Weyl (RCW) geometries, and their associated Brownian motions. In this setting, the drift vector field is the metric conjugate of the trace-torsion one-form, and the laplacian defined by the RCW connection is the differential generator of the Brownian motions. We extend this to the state-space of non-relativistic quantum mechanics and discuss the relation between a non-canonical quantum RCW geometry in state-space associated with the gradient of the quantum-mechanical expectation (...) value of a self-adjoint operator given by the generalized laplacian operator defined by a RCW geometry. We discuss the reduction of the wave function in terms of a RCW quantum geometry in state-space. We characterize the Schroedinger equation in terms of the RCW geometries and Brownian motions. Thus, in this work, the Schroedinger field is a torsion generating field, both for the linear and non-linear cases. We discuss the problem of the many times variables and the relation with dissipative processes, and the role of time as an active field, following Kozyrev and a recent experiment in non-relativistic quantum systems. We associate the Hodge dual of the drift vector field with a possible angular-momentum source for the phenomenae observed by Kozyrev. (shrink)

A fiber bundle constructed over spacetime is used as the basic underlying framework for a differential geometric description of extended hadrons. The bundle has a Cartan connection and possesses the de Sitter groupSO(4, 1) as structural group, operating as a group of motion in a locally defined space of constant curvature (the fiber) characterized by a radius of curvatureR≈10−13 cm related to the strong interactions. A hadronic matter field ω(x, ζ) is defined on the bundle space, withx the spacetime coordinate (...) and ζ varying in the local fiber. The components of a generalized tensor current ℑ μab (M) (x) are introduced, involving a bilinear expression in the fields ω(x, ζ) and ωΔ(x, ζ) integrated over the local fiber at the pointx. This hadronic matter current is considered as a source current for the underlying fiber geometry by coupling it in a gauge-invariant manner to the curvature expressions derived from the bundle connection coefficients, which are associated here with strong interaction effects, i.e., play the role of meson fields induced in the geometry. Studying discrete symmetry transformations between the 16 differently soldered Cartan bundles, a generalized matter-antimatter conjugation Ĉ is established which leaves the basic current-curvature equations Ĉ-invariant. The discrete symmetry transformation Ĉ turns out to be the direct product of an ordinary charge conjugation for the Dirac point-spinor part of ω(x, ζ) and an internal $\hat P\hat T$ transformation applied globally on the bundle to the fiber (i.e., de Sitter) part of ω(x, ζ).

When the “object” gazed at is called Africa and when the gazing subject is Africa, the observer cannot help but conclude that any gaze that is related to Africa is an intersection of gazes calling forth several questions: Who is looking at Africa? What is Africa looking at? Who looks at the one who is looking at Africa? Two problems emerge from this: the identification of the subject, and the discrimination among objects and themes produced by the limited scope of (...) these gazes. If the gaze at (or of) Africa is an intersection of perspectives, these perspectives will only find stability if they are related to the African history that is in the making. This is a plural history, for geographic diversity, and the multiplicity of acting figures and sociopolitical organizations give African history a “changeable and diverse” character. Any evaluation of the relationship of Africans to their history must be an attempt, a sketch that makes no pretense of providing a unique and certain interpretation of the African lived experience (Erlebnis) by implementing the kind of controlling philosophy of history that fixes the beginning, the length, and the order of a people's history. It is more a question of restating, with the uncertainty that characterizes any evaluation of a specific history, the problem of the relationship of African history to its becomings. How, by which conditions and through which actors does this plural history speak its moments of creation today? At its heart, how does it articulate the conflicting overlap of the gravity of existing institutions and the audacity of creation? The exploration of these questions first centers around the often discussed theme of African identity (self). The stakes at this level involve the detachment of the conditions of a dynamic re-appropriation from this notion of identity - at the very moment when globalization is conjugating itself by turns in the imperative, the indicative, and the conditional. Next, the examination will focus on relationships to otherness (the other). How can intersubjective relations be declined differently? (shrink)

The two Heisenberg Uncertainties (UR) entail an incompatibility between the two pairs of conjugated variables E, t and p, q. But incompatibility comes in two kinds, exclusive of one another. There is incompatibility defineable as: (p → − q) & (q→ − p) or defineable as [(p →− q) & (q →− p)] ↔ r. The former kind is unconditional, the latter conditional. The former, in accordance, is fact independent, and thus a matter of logic, the latter fact dependent, and (...) thus a matter of fact. The two types are therefore diametrically opposed. In spite of this, however, the existing derivations of the Uncertainties are shown here to entail both types of incompatibility simultaneously. Δ E Δ t ≥ h is known to derive from the quantum relation E = hν plus the Fourier relation Δ ν Δ t ≥ 1. And the Fourier relation assigns a logical incompatibility between Δ ν = 0, Δ t = 0. (Defining a repetitive phenomenon at an instant t → 0 is a self contradictory notion.) An incompatibility, therefore, which is fact independent and unconditional. How can one reconcile this with the fact that Δ EΔ t exists if and only if h > 0, which latter supposition is a factual truth, entailing that a Δ E = 0, Δ t = 0 incompatibility should itself be fact dependent? Are we to say that E and t are unconditionally incompatible (via Δ ν Δ t ≥ 1) on condition that E = hν is at all true? Hence, as presently standing, the UR express a self-contradicting type of incompatibility. To circumvent this undesirable result, I reinterpret E = hν as relating the energy with a period. Though only one such period. And not with frequency literally. (It is false that E = ν. It is true that E = ν times the quantum.) In this way, the literal concept of frequency does not enter as before, rendering Δ ν Δ t ≥ 1 inapplicable. So the above noted contradiction disappears. Nevertheless, the Uncertainties are derived. If energy is only to be defined over a period, momentum only over a distance (formerly a wavelength) resulting during such period, thus yielding quantized action of dimensions Et = pq, then energies will become indefinite at instants, momenta indefinite at points, leading, as demanded, to (symmetric!) Δ E Δ t = Δ p Δ q ≥ h’s. (shrink)

A central issue of cognitive neuroscience is to understand how a large collection of coupled neurons combines external signals with internal memories into new coherent patterns of meaning. An external stimulus localized at some input spreads over a large assembly of coupled neurons, building up a collective state univocally corresponding to the stimulus. Thus, the synchronization of spike trains of many individual neurons is the basis of a coherent perception. Based on recent investigations of homoclinic chaotic systems and their synchronization, (...) a novel conjecture for the dynamics of single neurons and, consequently, for neuron assemblies is formulated. Homoclinic chaos is proposed as a suitable way to code information in time by trains of equal spikes occurring at apparently erratic times. In order to classify the set of different perceptions, the percept space can be given a metric structure by introducing a distance measure between distinct percepts. The distance in percept space is conjugate to the duration of the perception in the sense that an uncertainty relation in percept space is associated with time-limited perceptions. This coding of different percepts by synchronized spike trains entails fundamental quantum features which are not restricted to microscopic phenomena. It is conjectured that they are related to the details of the perceptual chain rather than depending on Planck's action. (shrink)

In this article, I draw resources from Deleuze's Difference and Repetition to develop an explanation and critique of invasive policing techniques on certain populations in the United States. First, I analyse recent studies revealing the neighbourhood effects of aggressive policing on those who never directly encounter officers. Second, I use Deleuze's concepts of the virtual, potentiality, the Idea and problems to illuminate the limitations to studying these effects that are inherent in a social scientific approach. I then use Deleuze's discussion (...) of the Image of Thought to theorise a racialised Image of the Human that justifies the aggressive policing policies in certain neighbourhoods. I argue instead for an open, unsettled, in-process category of the human that continues to creatively actualise. Finally, I offer two normative claims that again derive from Deleuze's philosophy: the first is a preliminary strategy for mitigating the non-localisable and virtual effects of policing policy by ‘conjugating’ oneself in a complex set of neighbourhood relations, particularly in response to inequitably distributed spaces of oppression; the second is an attempt to avoid reducing humanity to calculability by ‘fully explicating’ the other. In combination, the goal is to undermine the dogmatic Images of Thought and the Human that ground oppressive policing practices, and to foster an intensive potentiality for newness that might take these Images' place.

The stability theory of first order theories was initiated by Saharon Shelah in 1969. The classification of abstract elementary classes was initiated by Shelah, too. In several papers, he introduced non-forking relations. Later, Shelah [17, II] introduced the good non-forking frame, an axiomatization of the non-forking notion.We improve results of Shelah on good non-forking frames, mainly by weakening the stability hypothesis in several important theorems, replacing it by the almost λ-stability hypothesis: The number of types over a model of (...) cardinality λ is at most λ+.We present conditions on Kλ, that imply the existence of a model in Kλ+n for all n. We do this by providing sufficiently strong conditions on Kλ, that they are inherited by a properly chosen subclass of Kλ+. What are these conditions? We assume that there is a ‘non-forking’ relation which satisfies the properties of the non-forking relation on superstable first order theories. Note that here we deal with models of a fixed cardinality, λ.While in Shelah [17, II] we assume stability in λ, so we can use brimmed models, here we assume almost stability only, but we add an assumption: The conjugation property.In the context of elementary classes, the superstability assumption gives the existence of types with well-defined dimension and the ω-stability assumption gives the existence and uniqueness of models prime over sets. In our context, the local character assumption is an analog to superstability and the density of the class of uniqueness triples with respect to the relation ≼bs is the analog to ω-stability.

This paper examines the contribution of the PhD dissertation of the American cytologist Michael F. Guyer (1874-1959) to the early establishment (in 1902-1903) of the parallel relationship between cytological chromosome behaviour in meiosis and Mendel's laws. Guyer's suggestions were among the first, which attempted to relate the variation observed in the offspring in hybridisation studies by a coherent cytological chromosome mechanism to meiosis before the rediscovery of Mendel's principles. This suggested for the first time that the chromosome mechanism involved a (...) conjugation of maternal and paternal chromosomes during the synapsis followed by a segregation of parental chromosomes in the final germ cells and a random union of the final germ cells in the fertilization. It shows that this early suggestion was similar to William Austin Cannon's later chromosome proposal attempting to explain Mendel's principles and had some influence on Walter Sutton's cytological suggestion explaining correctly the behaviour of Mendel's particle by 1903.

Moving from the contemporary transformations of labor as form of production, this dissertation tries to question the role that 'knowledge' has, both as element of capitalist production and as its subverting tool. By setting a parallelism between Capital's mechanism and the workings of the Imagination, this study tracks the genealogy of 'Immaterial labor', main figure of this transformation, back to Marx's notion of phantasmagoria and to the reading that Walter Benjamin gave of it . It develops a path still latent (...) in Benjamin's work but already by him indicated---whose importance has been neglected by the critical work of the last twenty years---, of a positive role of the image within the event of phantasmagoria. Such positive role of the image is detected by this study as knowledge that occurs, in contemporaneity, mainly through images. It is so defined a first feature of this knowledge, common to both capital and imagination. By inserting itself within the contemporary attention to the productive aspect of Imagination and its influence on economy ; this study conjugates this 'knowledge in images'--- with the 'creative, materialistic' role of the image in contemporary theories of knowledge . A powerful figure comes out of this reflection: sense , which this study proposes as materialist Concept and opposes to the aconceptual relations established by capital. Product of phantasmagoria and opening to poetics, sense is the concept able to function as bridge to the possibility of a 'practical knowledge'. With these elements, this study proposes to add to the contemporary notion of 'cognitive capitalism' , a notion of 'cognitive materialism' which, by giving justice to a material side of immaterial labor, chooses to give back to poverty the force of potentia, of affirmative activity.

Introduction The paradigm shift to a knowledge‐based economy has incremented the use of personal information applied to health‐related activities, such as biomedical research, innovation, and commercial initiatives. The convergence of science, technology, communication and data technologies has given rise to the application of big data to health; for example through eHealth, human databases and biobanks. Methods In light of these changes, we enquire about the value of personal data and its appropriate use. In order to illustrate the complex ground on (...) which big data applied to health develops, we analyse the current situation of the European Union and two cases: the Catalan VISC+/PADRIS and the UK Biobank, as perspectives. Discussion and conclusions Personal health‐related data in the context of the European Union is being increasingly used for big data projects under diverse schemes. There, public and private sectors participate distinctively or jointly, pursuing very different goals which may conflict with individual rights, notably privacy. Given that, this paper advocates for stopping the unjustified accumulation and commercialisation of personal data, protecting the interests of citizens and building appropriate frameworks to govern big data projects for health. A core tool for achieving such goals is to develop consent mechanisms which allow truly informed but adaptable consent, conjugated with the engagement of donors, participants and society. (shrink)

A formulation of relativistic quantum mechanics is presented independent of the theory of Hilbert space and also independent of the hypothesis of spacetime manifold. A hierarchy is established in the nondistributive lattice of physical ensembles, and it is shown that the projections relating different members of the hierarchy form a semigroup. It is shown how to develop a statistical theory based on the definition of a statistical operator. Involutions defined on the matrix representations of the semigroup are interpreted in terms (...) ofCPT conjugations. The theory of particles of spin one-half and systems with higher spin is developed from first principles. Methods are also developed for defining energy, momentum, orbital angular momentum, and weighted spacetime coordinates without reference to a manifold. (shrink)

This article, based on original research from 57 villages in four provinces from North and East India, sheds light on a hitherto unexplored gendered impact of colorism in facilitating noncustomary cross-region marriage migrations in India. Within socioeconomically marginalized groups from India’s development peripheries, the hegemonic construct of fairness as “capital” conjoins with both regressive patriarchal gender norms governing marriage and female sexuality and the monetization of social relations, through dowry, to foreclose local marriage options for darker-hued women. This dispossession (...) of matrimonial choice forces women to “voluntarily” accept marriage proposals from North Indian bachelors, who are themselves faced with a bride shortage in their own regions due to skewed sex ratios. These marriages condemn cross-region brides to new forms of gender subordination and skin-tone discrimination within the intimacy of their marriages, and in everyday relations with conjugal families, kin, and rural communities. Because of colorism, cross-region brides are exposed to caste-discriminatory exclusions and ethnocentric prejudice. Dark-skin shaming is a strategic ideological weapon employed to extract more labor from them. The article extends global scholarly discussion on the role of colorism in articulating new forms of gendered violence in dark-complexioned, poor rural women’s lives. (shrink)

Adaptive mutation is defined as a process that, during nonlethal selections, produces mutations that relieve the selective pressure whether or not other, nonselected mutations are also produced. Examples of adaptive mutation or related phenomena have been reported in bacteria and yeast but not yet outside of microorganisms. A decade of research on adaptive mutation has revealed mechanisms that may increase mutation rates under adverse conditions. This article focuses on mechanisms that produce adaptive mutations in one strain of Escherichia coli, FC40. (...) These mechanisms include recombination-induced DNA replication, the placement of genes on a conjugal plasmid, and a transient mutator state. The implications of these various phenomena for adaptive evolution in microorganisms are discussed. BioEssays 22:1067–1074, 2000. © 2000 John Wiley & Sons, Inc. (shrink)

Most of what is told in this paper has been told before by the same author, in a number of publications of various kinds, but this is the first time that all this material has been brought together and treated in a uniform way. Smaller errors in the earlier publications are corrected here without comment. It has been known since the 1920s that quadratic equations played a prominent role in Babylonian mathematics. See, most recently, Høyrup (Hist Sci 34:1–32, 1996, and (...) Lengths, widths, surfaces: a portrait of old Babylonian algebra and its kin. Springer, New York, 2002). What has not been known, however, is how quadratic equations came to play that role, since it is difficult to think of any practical use for quadratic equations in the life and work of a Babylonian scribe. One goal of the present paper is to show how the need to find solutions to quadratic equations actually arose in Mesopotamia not later than in the second half of the third millennium BC, and probably before that in connection with certain geometric division of property problems. This issue was brought up for the first time in Friberg (Cuneiform Digit Lib J 2009:3, 2009). In this connection, it is argued that the tool used for the first exact solution of a quadratic equation was either a clever use of the “conjugate rule” or a “completion of the square,” but that both methods ultimately depend on a certain division of a square, the same in both cases. Another, closely related goal of the paper is to discuss briefly certain of the most impressive achievements of anonymous Babylonian mathematicians in the first half of the second millennium BC, namely recursive geometric algorithms for the solution of various problems related to division of figures, more specifically trapezoidal fields. For an earlier, comprehensive (but less accessible) treatment of these issues, see Friberg (Amazing traces of a Babylonian origin in Greek mathematics. WorldScientific, Singapore 2007b, Ch. 11 and App. 1). (shrink)

A central issue of cognitive neuroscience is to understand how a large collection of coupled neurons combines external signals with internal memories into new coherent patterns of meaning. An external stimulus localized at some input spreads over a large assembly of coupled neurons, building up a collective state univocally corresponding to the stimulus. Thus, the synchronization of spike trains of many individual neurons is the basis of a coherent perception. Based on recent investigations of homoclinic chaotic systems and their synchronization, (...) a novel conjecture for the dynamics of single neurons and, consequently, for neuron assemblies is formulated. Homoclinic chaos is proposed as a suitable way to code information in time by trains of equal spikes occurring at apparently erratic times. In order to classify the set of different perceptions, the percept space can be given a metric structure by introducing a distance measure between distinct percepts. The distance in percept space is conjugate to the duration of the perception in the sense that an uncertainty relation in percept space is associated with time-limited perceptions. This coding of different percepts by synchronized spike trains entails fundamental quantum features which are not restricted to microscopic phenomena. It is conjectured that they are related to the details of the perceptual chain rather than depending on Planck's action. (shrink)

It is shown that the Hilbert space formalism of quantum mechanics can be derived as a corrected form of probability theory. These constructions yield the Schrödinger equation for a particle in an electromagnetic field and exhibit a relationship of this equation to Markov processes. The operator formalism for expectation values is shown to be related to anL 2 representation of marginal distributions and a relationship of the commutation rules for canonically conjugate observables to a topological relationship of two manifolds is (...) indicated.
