The logical structure of Quantum Mechanics (QM) and its relation to other fundamental principles of Nature has been for decades a subject of intensive research. In particular, the question whether the dynamical axiom of QM can be derived from other principles has been often considered. In this contribution, we show that unitary evolutions arise as a consequences of demanding preservation of entropy in the evolution of a single pure quantum system, and preservation of entanglement in the evolution of composite quantum (...) systems. 6.

Completeness is shown for several versions of Girard's linear logic with respect to Petri nets as the class of models. One logic considered is the -free fragment of intuitionistic linear logic without the exponential !. For this fragment Petri nets form a sound and complete model. The strongest logic considered is intuitionistic linear logic, with ,&, and the exponential ! , and forms of quantification. This logic is shown sound and complete with respect to atomic nets , though only once (...) we add extra axioms specific to the Petri-net model. The logic is remarkably expressive, enabling descriptions of the kinds of properties one might wish to show of nets; in particular, negative properties, asserting the impossibility of an assertion, can also be expressed. Unfortunately, with respect to this logic, whether an assertion is true of a finite net becomes undecidable. (shrink)

In a comparative context, Danish national identity and political culture combine features of what is often referred to as East European integral nationalism , typical of smaller, recently independent nation-states, and the patriotic concept of citizenship in the older West European state nations. The explanation of this apparent paradox is that Denmark belongs to both families. A former multinational, composite state in 1864 was cut down to a size that enabled a class of about 60,000 peasant-farmers to establish an ideological (...) hegemony in the diminished and nationalized, yet still fully legitimate, state. A libertarian ideology of social solidarity ended up dominating this rump nationstate. The net result in Denmark has been a political mentality stressing the importance of consensus among all the people, in Danish ‘folk’. This populism or ‘popular’ ideology ( folkelighed ) is shared by virtually all political parties. Thus Danish modernity was characterized by industrialized agrarian capitalism with a socially and nationally homogeneous face, i.e. a folkish democracy which I have elsewhere baptized ‘Peasants and Danes’ (Østergård, 1992).

Michèle Le Dœuff discusses the revival of feminism in France, including the phenomenon of state-sponsored feminism, such as government support for "parity": equal numbers of women and men in government. Le Dœuff analyzes the strategically patchy application of this revival and remains wary about it. Turning to the work of seventeenth-century philosopher Gabrielle Suchon, Le Dœuff considers her concepts of freedom, servitude, and active citizenship, which may well, she argues, have influenced Jean-Jacques Rousseau. Le Dœuff favorably juxtaposes the active citizenship (...) defended by Suchon with the kind of citizenship implicitly supported by recent French government feminism. (shrink)

Michèle Le Dœuff speculates about why the parity movement enjoyed attention and sympathy in France over recent years. She discusses recent developments in "State-handled" feminism, and the resurgence of interest in feminist debate in France. Perhaps patriarchy is an institution more fundamental than the State?

Earlier studies of the term wén 文 in pre-Qín texts do not fully explain the relation-ship between its basic meaning ‘ pattern’ and its more abstract meanings ‘moral refinement’ and ‘tradition of conventionalized behavior’. In contrast, I argue that, when used as an epithet describing individuals in pre-Zhànguó texts, wén meant something like ‘awe-inspiringly beautiful’, rather than ‘accomplished’ or ‘cultured’ as proposed in earlier studies and translations. Wearing clothes embroidered with ‘rank indicating emblems’ and possessing ‘decorated’ accoutrements signaling authority were (...) the prerogatives of members of the high nobility. It was not an acquired property. The meaning ‘awe-inspiringly beautiful’ derived from ‘decorative pattern’ through metaphorical extension. This analysis of wén helps us avoid the anachronistic moral interpretations often found in traditional commentaries and in modern translations of pre-Zhànguó texts, and improves our understanding of the role played by physical appearance in the construction of social hierarchies in the pre-Zhànguó period. In contrast, in Zhànguó-period texts such as the Zuǒzhuàn, wén was reanalyzed in moral terms, thereby giving rise to adjectival uses referring to ‘morally refined’ ‘noble men’. In the Lúnyǔ, adjectival wén in the sense ‘morally refined’ is applied to dynasties. Nominalized versions of adjectival wén then give rise to even more abstract uses referring to the ‘moral refinement’ of the Zhōu, that is, the ideal ‘patterns of social mores and conventionalized practices established by the former kings’, as in Lúnyǔ 9.5. Such uses of wén are often translated into English as culture. However, since the words culture and wén derive metaphorically from different basic meanings, i.e., ‘growing/cultivating’ and ‘decorating/applying an external pattern’, respectively, and since they refer to different, language- and tradition-specific concepts of ‘conventionalized behavior’ or ‘culture’, such translations are often infelicitous or misleading.

In this dissertation I trace (i) the emergence and different stages of the use of the term wén in pre-Qín texts to refer to language-specific conceptualizations of ‘conventionalized behavior’ and (ii) the emergence of the use of the English term culture as a translation of the term wén and as an analytical concept in discussions of ‘cultural identity’ in early China. I do so by proposing a linguistic anthropological approach to the study of historical changes in collectively shared conceptualizations of (...) ‘conventionalized behavior’ through lexical changes in text corpora. Combining theories of metaculture with theories of lexicalization enables me to analyze pre-Qín concepts of ‘tradition’ or ‘culture’ as language-specific metacultural concepts which are anchored in particular historical contexts. This dissertation contributes to our understanding of the term wén in three ways. First, I argue that metacultural uses of wén did not exist in the pre-Zhànguó period. At that time when wén was used to refer to positive attributes of individuals of noble rank, it meant ‘awe-inspiringly beautiful.’ This use of wén derived from more the basic meaning ‘decorative pattern’ through processes of metaphorical extension and abstraction. This dissertation thereby offers new insight into the social importance of externally visible beauty in early Zhōu society by proposing that pre-Zhànguó uses of wén referred to physical appearance rather than acquired moral traits (as proposed in the Chinese commentarial tradition). Second, I argue that metacultural uses of wén referring to the abstract concept of ‘(patterns in) conventionalized behavior’ developed in the Zhànguó period (481-221 BCE) from the earlier meaning of ‘awe-inspiringly beautiful.’ By providing a chronology of these changes, I avoid the anachronistic interpretations of wén which originated in the Chinese commentarial tradition and which have continued to influence the way scholars translate the term to the present day. Third, I show that the wide-spread assumption that wén means ‘culture’ is a relatively recent phenomenon that owes more to the increasing popularity of the term culture in the English language over the last two centuries than to a deepening of our understanding of the pre-Qín metacultural concept referred to by the term wén.

The aim of this article is to explore website interactivity as discourse. Whereas the use of writing, images and layout in web design has been explored extensively, interactivity, that is, interactions between a web user and the website system, remains an underdeveloped area of discourse studies. To analyze interactivity as discourse, the article uses data from a research project on offline and online shopping for electronics, viewing the offline-online relationship as recontextualization in the sense that webshop interactivity represents and transforms (...) in-store shopping actions. Using a methodology that combines analytical framework for interactive sites and approach to discourse analysis, the article maps cursor resources and interactive webshop features as actions and compares them to the actions that constitute in-store shopping. On this basis, the article offers reflections on how interactivity plays a defining role in the digital resemiotization of social practices. (shrink)

We introduce and study certain classes of optimization problems over the real numbers. The classes are defined by logical means, relying on metafinite model theory for so called R-structures . More precisely, based on a real analogue of Fagin's theorem [12] we deal with two classes MAX-NPR and MIN-NPR of maximization and minimization problems, respectively, and figure out their intrinsic logical structure. It is proven that MAX-NPR decomposes into four natural subclasses, whereas MIN-NPR decomposes into two. This gives a real (...) number analogue of a result by Kolaitis and Thakur [13] in the Turing model. Our proofs mainly use techniques from [17]. Finally, approximation issues are briefly discussed.

Indledning til “Om spørgsmålet: Hvad er oplysning?” af Moses Mendelssohn.

Fifty years ago, in 1961, Feinstein published his first path-breaking articles leading to his seminal work Clinical Judgement and to the establishment of clinical epidemiology. Feinstein had an Aristotelian approach to scientific method: methods must be adapted to the material examined. Feinstein died 10 years ago and few years before his death he concluded that efforts to promote a person-oriented medicine had failed. He criticised medicine for not having recognized that only persons can suitably observe, evaluate and rate their own (...) health status. Feinstein’s position was—as in Clinical Judgement—methodological. He didn’t espouse ethical principles. He pointed to methodological deficiencies in clinical epidemiology and evidence-based medicine. In this article we’ll provide a framework for understanding and justifying Feinstein’s call for a person-oriented medicine which recognizes patients as co-actors in clinical reasoning. It’s argued that craftsmanship and practical wisdom are integrated in clinical judgement and reasoning and that clinical reasoning is not only about means to achieve the end, health. We do also reason and deliberate about ends. The ‘defining end’ of medicine (health) has continuously been negotiated and so been the object of deliberation. For centuries among professionals, in recent years among professionals and patients. These negotiations and deliberations lead to ongoing specifications of health as a ‘guiding end’, i.e. an end guiding clinical reasoning about what to do in particular situations. Feinstein’s self-critical account to clinical epidemiology at the end of his professional career reflects the fact that patients during the last 30–40 years (i.e. in the period after the publication of Clinical Judgement) widely have been recognized as persons with rights to autonomy. Feinstein’s lesson is, however, that espousing and recognizing ethical ideals is not enough. A change of clinical practice and its methods is necessary. His critique also implies that clinical epidemiology and evidence-based medicine as practiced haven’t provided such a turn. (shrink)

Civic agriculture is an approach to agriculture and food production that—in contrast with the industrial food system—is embedded in local environmental, social, and economic contexts. Alongside proliferation of the alternative food projects that characterize civic agriculture, growing literature critiques how their implementation runs counter to the ideal of civic agriculture. This study assesses the relevance of three such critiques to urban farming, aiming to understand how different farming models balance civic and economic exchange, prioritize food justice, and create socially inclusive (...) spaces. Using a case study approach that incorporated interviews, participant observation, and document review, I compare two urban farms in Baltimore, Maryland—a “community farm” that emphasizes community engagement, and a “commercial farm” that focuses on job creation. Findings reveal the community farm prioritizes civic participation and food access for low-income residents, and strives to create socially inclusive space. However, the farmers’ “outsider” status challenges community engagement efforts. The commercial farm focuses on financial sustainability rather than participatory processes or food equity, reflecting the use of food production as a means toward community development rather than propagation of a food citizenry. Both farms meet authentic needs that contribute to neighborhood improvement, though findings suggest a lack of interest by residents in obtaining urban farm food, raising concerns about its appeal and accessibility to diverse consumers. Though not equally participatory, equitable, or social inclusive, both farms exemplify projects physically and philosophically rooted in the local social context, necessary characteristics for promoting civic engagement with the food system.

Om spørgsmålet: Hvad er oplysning? af Moses Mendelssohn oversat af Anders Hee Nørbjerg Poulsen.

Standard models of adolescent risk taking posit that the cognitive abilities of adolescents and adults are equivalent, and that increases in risk taking that occur during adolescence are the result of socio emotional differences in impulsivity, sensation seeking, and lack of self-control. Fuzzy-trace theory incorporates these socio emotional differences. However, it predicts that there are also cognitive differences between adolescents and adults, specifically that there are developmental increases in gist-based intuition that reflects understanding. Gist understanding, as opposed to verbatim-based analysis, (...) generally has been hypothesized to have a protective effect on risk taking in adolescence. Gist understanding is also an essential element of informed consent regarding risks in medical decision- making. Evidence thus supports the argument that adolescents’ status as mature minors should be treated as an exception rather than a presumption, because accuracy in verbatim analysis is not mature gist understanding. Use of the exception should be accompanied by medical experts’ input on the bottom-line gist of risks involved in treatment. (shrink)

In this article we pose three questions: 1) What are the questions that gave rise to the introduction of the concept and subdiscipline of meta-ethics? 2) What characterises the view of meta-ethics as a subdiscipline of moral philosophy? And 3) is it in fact possible to uphold a systematic distinction between normative moral philosophy and meta-ethics in a way that allows us to see these two aspects of moral philosophy as independent subdisciplines? In trying to answer these questions, we trace (...) two different roads in the shaping of the current understanding of meta-ethics: the introduction of the word in analytical moral philosophy and the characterisation of meta-ethics in the formative period of meta-ethics and in contemporary introductions. Among the characteristics ascribed to meta-ethics, we identify a special focus on normative neutrality, and we furthermore show that this idea of neutrality as the defining characteristic of meta-ethics cannot be upheld. Our aim is to show that meta-ethics cannot be characterised or construed in a way that is normatively neutral and independent of other work done in normative ethics. We therefore challenge the claim that meta-ethics makes up a subdiscipline that is independent of other work done in moral philosophy. Instead, we suggest a reflective view of the relationship between meta-ethics and normative ethics, according to which we should acknowledge that meta-ethics is inherently normative, and that meta-ethical questions are interwoven with normative questions in moral philosophy.

The societal dynamism of modernity results in the theoretical upgrading and the actual development of personal reflective capacities, for example abstract reasoning, Kantian morality, and the development of the idiocentered perspective. These capacities are created in the disembedding of prereflective capacities, for example context-sensitive intelligence, care-morality, and mundocenteredness. The reflective capacities become the prerequisite of further modernization. The development-potential offered by the demands of modernity is accompanied by a risk of assimilative stress, for example pseudological reasoning, varieties of postmodernism, making (...) a fetish of the medium, and the forfeit of the morality of care.
