Women's small share of professional and managerial occupations compared with their share of the total labor force is examined for the 11 largest racial and ethnic minorities in the United States. Gender-related characteristics—women's labor force participation rates, marital status, and the sex ratio—influence women's share of the top jobs, as do class and ethnic variables such as place of birth, population size, and class of worker. Labor market gender inequality is greatest among the smaller, more affluent minorities, many of whom (...) are recent immigrants to this country. The larger, frequently indigenous, minority groups exhibit less of this kind of inequality. Minority and gender status intersect, so that men monopolize surplus resources among the more affluent minority groups and use these resources to secure a more advantaged labor market position.

In dominant discourses, migrants are mostly perceived as either victims or villains but rarely as political subjects and democratic constituents. Challenging this view, the aim of the article is to rethink democracy with respect to migration struggles. I argue that movements of migration are not only consistent with democracy but also provide a decisive impetus for actualizing democratic principles in the context of debates about the crisis of representation and post-democracy. Drawing on the work of Jacques Rancière, Étienne Balibar and (...) Ernesto Laclau and Chantal Mouffe, I develop a theory of radical democracy as practice, which, starting from the proposed notion of ‘democratic difference’, goes beyond the fixation on democratic regimes and focuses on contentious practices of enacting democratic principles. I articulate these theoretical concepts by analysing how refugees in Germany have managed to break out of a marginalized position and have challenged their denial of rights through a protest march.

No other scientist may have had a greater impact on modern cosmology than the Belgian physicist, astronomer and priest Georges Lemaître. In 1927 he predicted the expansion of the universe on the basis of the cosmological field equations; and four years later he proposed what he called the primeval-atom hypothesis, the first version of the later big bang universe. In all his work on cosmology the cosmological constant Λ played a significant role. A recognized expert in the theory of general (...) relativity, Lemaître also contributed significantly to the theoretical clarification of local and global singularity problems. Still, when he died in 1968, at a time when the standard big bang model celebrated its first victories, he was largely forgotten or recalled only as a somewhat shadowy figure of the past. This essay reviews in a historical context the scientific work of Lemaître with particular attention to his seminal contributions in the decade between 1925 and 1934. (shrink)

This article examines what comes to pass when philosophical practitioners start working in the institutional environment of a hospital, with its unique norms and culture through the experience of three philosophical practitioners in Norway. It finds that that a notable characteristic of these practitioners is their effort to avoid taking on the traditional helper role, which they perceive that other hospital professions are representing. Their ideal is to approach “life here and now” with openness, acceptance, curiosity, and wondering, while simultaneously (...) supporting a serious, playful creativity in the search for new perspectives when relevant. For the patients, this offers a space where they can rediscover themselves as whole individuals, rather than rather only beings in need of help. The article concludes that philosophical practitioners have the potential to play a significant role within hospitals. (shrink)

In his Doctrine of Right, Immanuel Kant calls Moses Mendelssohn, the towering figure of the German and the Jewish Enlightenment, a ‘Rechtsforscher’—a legal scholar. Yet not only Kant, but numerous scholars of Natural law in the 18th and 19th centuries refer to and reflect on the juridical aspects of Mendelssohn’s work, in particular his thoughts on the law of contract. In this article, I hope to shed some light on this hitherto rather unexplored facet of Mendelssohn’s oeuvre. Mendelssohn develops his (...) theory of contract from the starting point of the officium amoris: the unenforceable ‘duty of love’ to exercise beneficence. Mendelssohn’s theory knows nothing yet of the modern contrast between altruism, distributive justice and ‘freedom of contract’. By exploring Mendelssohn’s theory, we will thus be able to catch a glimpse of the birth pangs of the modern Western discourse on the ‘freedom of contract’, which formed the backdrop as well as the jumping-off point of the development of a ‘liberal’ will theory of contract. Since this ‘liberal’ model is still the paradigm of how contract is mostly perceived today, Mendelssohn’s theory also exemplifies the possibility of an alternative to our own conceptualizations of contract that inescapably shape the way we think.

The Scandinavian working-life tradition is founded on ideas and values similar to the model of conductivity. However, although the Scandinavian working-life tradition is pragmatic and consensus seeking the model of conductivity is stringent following its principles. The pragmatic approach, here represented by the Danish program of “the developmental work,” has made it difficult to follow the vision of the program (to improve working conditions and at the same time meet social and environmental needs). Instead, the program has mainly targeted organizational (...) development in established companies, accepting the existing principles of wealth creation. The model of conductivity can strength the visions behind the pragmatic approach by its conceptualization of an alternative creation of wealth related to opportunities in current working life: a creation of wealth based on skill, creativity and networking among employees across the borders of the organizations and released from the language of management.

Le but de cet article est de montrer comment les logiques dites multivalentes peuvent être formulées dans le cadre de la logique dialogique. Pour formuler les règles de particule pour ces logiques on introduit l’idée de différents modes d’assertion. En donnant ensuite les règles de particule et les règles structurelles appropriées, on peut reconstruire dialogiquement les systèmes standards de logiques multivalentes. Cela est fait explicitement pour la logique `a trois valeurs de Łukasiewicz (L3c). En remplaçant la règle structurelle classique par (...) sa contrepartie intuitionniste on obtient des versions intuitionnistes de systèmes multivalents (par exemple L3i). Les systèmes dialogiques multivalents L3c et L3i sont illustrés par quelques exemples et pour conclure on formule les tableaux stratégiques correspondants. (shrink)

The story of superheavy elements - those at the very end of the periodic table - is not well known outside the community of heavy-ion physicists and nuclear chemists. But it is a most interesting story which deserves to be known also to historians, philosophers, and sociologists of science and indeed to the general public. This is what the present work aims at. It tells the story or rather parts of the story, of how physicists and chemists created elements heavier (...) than uranium or searched for them in nature. And it does so with an emphasis on the frequent discovery and naming disputes concerning the synthesis of very heavy elements. Moreover, it calls attention to the criteria which scientists have adopted for what it means to have discovered a new element. In this branch of modern science it may be more appropriate to speak of creation instead of discovery. The work will be of interest to scientists as well as to scholars studying modern science from a meta-perspective. (shrink)

Attempts to explain the periodic system as a manifestation of regularities in the structure of the atoms of the elements are as old as the system itself. The paper analyses some of the most important of these attempts, in particular such works that are historically connected with the recognition of the electron as a fundamental building block of all matter. The history of the periodic system, the discovery of the electron, and ideas of early atomic structure are closely interwoven and (...) transcend the physics–chemistry boundary. It is pointed out that J. J. Thomson's discovery of the electron in 1897 included a first version of his electron atomic model and that it was used to suggest how the periodic system could be understood microphysically. Thomson's theory did not hold what it promised, but elements of it were included in Niels Bohr's first atomic model. In both cases, Thomson's and Bohr's, the periodic system played an important role, heuristically as well as justificatory. (shrink)

This volume offers a critical analysis and illustration of the challenges and promises of ‘stateless’ law thought, pedagogy and approaches to governance - that is, understanding and conceptualizing law in a post-national condition. Confronting the ‘transnational challenge’ posed to the traditional theoretical and institutional structures that underlie the teaching and study of law in the university, the book brings new insight to the ongoing and crucial conversation about the future shape of legal scholarship, education and practice that is emblematic of (...) the early twenty-first century.

Telegraphy, the distant ancestor of Internet and GSM (Global System for Mobile Communications), was invented by Samuel Morse in 1838. One year later, William Grove invented the fuel cell. Although numerous highly successful innovations stemming from telegraphy may be observed, the development of fuel cells has been insignificant, slow, and erratic and has not yet resulted in notable positive socioeconomic effects. By comparing the modern development of fuel cells and hydrogen technology, that is, a potential radical innovation in energy generation, (...) with some aspects related to the evolution of two highly successful radical innovations, Internet and GSM, the author focuses on the role of innovation regimes and policy in a sectorial system of innovations perspective. In the slow pace in fuel cells and hydrogen technology development, two factors seem to interact negatively: weak and fragmented innovation regimes in the energy sector and the current hegemony of market-oriented R&D policies.

In the Heptateuch paraphrase, probably written in the first half of the fifth century A. D., its anonymous author embellishes the biblical narrative, which describes the temptation of the first humans in Paradise, with a strange detail: Adam and Eve, who before the Fall were blind and swathed in darkness, enjoy an extraordinary experience of light after eating the forbidden fruit, as promised by the devilish snake: The heavens glow with bright light and their eyes shine. This miraculous light, which (...) is not God’s gift, but the result of their rebellious and self-willed defiance of divine ordinance, symbolizes the presumptuousness of mankind’s progenitors in seeking to equal God. The metaphor of light is borrowed from the philosophic and religious ideas of Neoplatonism and of the mystery cults. These ideas suggest that a God-like status can be achieved through the individual pursuit of knowledge. The Heptateuch poet employs his depiction of the Fall to inveigh against such designs.

A mobile service robot performing a task for its user might not be able to accomplish its mission without help from other people present in the shared environment. In previous research, collaborative control has been studied as an interactive mode of operation with a robot, compensating for its limitations in autonomy. However, few studies of robots requesting assistance by detecting potential collaborators, directing its attention to them, addressing them, and finally obtaining help from them, have previously been performed in real-world (...) use contexts. This study focuses on a fetch-and-carry robot, Cero, which has been designed to operate in an office environment as an aid for motion-impaired users. During its missions, the robot sometimes needs help with loading or unloading an object. The main question for the study was: under what conditions are people willing to help when requested to do so by the robot? We were particularly interested in bystanders, i.e. people who happened to be in the environment but who did not “have any official business” with the robot. To answer these questions and to provide a better understanding of human–robot help-seeking situations, we conducted an experimental study in which subjects who had not encountered our service robot before were requested to assist it with a task. The results of the study confirm that bystanders can to some degree be expected to help in robot missions, but that their willingness to help the robot depends on the situation and state of occupation that people are in when requested to interact with and assist the robot.

Dialogical logic is a game-theoretical approach to logic. Logic is studied with the help of certain games, which can be thought of as idealized argumentations. Two players, the Proponent, who puts forward the initial thesis and tries to defend it, and the Opponent, who tries to attack the Proponent’s thesis, alternately utter argumentative moves according to certain rules. For a long time the dialogical approach had been worked out only for classical and intuitionistic logic. The seven papers of this dissertation (...) show that this narrowness was uncalled for. The initial paper presents an overview and serves as an introduction to the other papers. Those papers are related by one central theme. As each of them presents dialogical formulations of a different non-classical logic, they show that dialogical logic constitutes a powerful and flexible general framework for the development and study of various logical formalisms and combinations thereof. As such it is especially attractive to logical pluralists that reject the idea of “the single correct logic”. The collection contains treatments of free logic, modal logic, relevance logic, connexive logic, linear logic, and multi-valued logic. (shrink)

Special purpose service robots have already entered the market and their users’ homes. Also the idea of the general purpose service robot or personal robot companion is increasingly discussed and investigated. To probe human–robot interaction with a mobile robot in arbitrary domestic settings, we conducted a study in eight different homes. Based on previous results from laboratory studies we identified particular interaction situations which should be studied thoroughly in real home settings. Based upon the collected sensory data from the robot (...) we found that the different environments influenced the spatial management observable during our subjects’ interaction with the robot. We also validated empirically that the concept of spatial prompting can aid spatial management and communication, and assume this concept to be helpful for Human–Robot Interaction design. In this article we report on our exploratory field study and our findings regarding, in particular, the spatial management observed during show episodes and movement through narrow passages. Keywords: COGNIRON, Domestic Service Robotics, Robot Field Trial, Human Augmented Mapping, Human–Robot Interaction, Spatial Management, Spatial Prompting. (shrink)

The history of the Greenlandic mineral cryolite is outlined from its discovery in late-eighteenth century to the mid-nineteenth century, when its potential for industrial use was first recognized by the Danish chemist Julius Thomsen. During the 1850s, several attempts were made to exploit cryolite for the production of soda and/or aluminium, of which only the soda process became implemented on an industrial scale. The main part of the paper examines the early cryolite soda manufacture, its chemical basis as well as (...) its industrial significance. The focus is thus the intersection of chemical science and technology. It is argued that Thomsen's process depended intimately on current chemical knowledge, and that, with regard to the science-technology relationship, the cryolite soda manufacture signified a new kind of industrial chemistry.

This paper is an argument to the effect that a certain view about mental representing, together with some very liberal constraints on the brain as a dynamic system, entails that the organism will tend to form adaptive mental representations of its environment. To show this, it will first be argued that although mental representing is a common thing indeed, representationalism, in the most important sense of that term (indirect representationalism), is false. Three different views about pictorial thinking (mental imagery, intuitive (...) representing) are then contrasted, two of which are tied to this brand of representationalism and one of which is not. The latter view, versions of which have sometimes been presented as ”simulation” theories of imagery, is here generalised to cover all kinds of mental representation. Two models of the brain are then presented in which learning of adaptive representations follows from this theory together with certain biologically plausible constraints. (shrink)
