We study price formulas suited for empirical research in financial markets in which put–call parity is satisfied. We find a connection between risk and the bid–ask spread. We further study the compatibility of the model with market frictions, and determine market subsets where the Fundamental Theorem of Asset Pricing applies. Finally, we characterize the price formula.

Japanese conversational data reveal that Japanese speakers produce, and recipients orient to, smaller units of talk than what the conventional notion of a `turn constructional unit' represents. Unlike TCUs, such units may be grammatically, prosodically and pragmatically incomplete and may happen on the sub-phrasal level of discourse, as Japanese conversationalists prosodically break up even a single semantic constituent with the insertion of an interactional particle. In this article, I give numerous examples of how such practices of separating a segment of (...) talk are not random but are precisely embedded in the sequential organization of talk that participants co-create. I argue that such segmentation contributes to the interactional co-construction of a turn so as to highlight specifically a `move' Within the larger action that is implemented by the TCU. Doing so thereby provides opportunities for the participants to deal with local contingency problems without changing the global level of the pragmatic work of the turn. (shrink)

Sara Ahmed’s enquiry on what it means for sexuality to be lived as oriented from the work Queer Phenomenology inspired the art series ‘A Sexual Series’, based on post-humanist theory and asexual experience. Shapes of performative alter egos materialized from a queer cyborg position of technologically enhanced crip experiences (the strong symbolical constructing process of straightening scoliosis surgery). From being a glitch of the past towards a post-individualist future, the artificial intelligence sexbot is a metaphoric, elevated cyborg drag version of (...) the artist to embody asexuality and queer Otherness. Based on multitudes of CUNTraDICKtions to encourage self-reflection, the series explores the complexities of ob/scene and on/scene performances; the position of a sex positive asexual as well as questions of belonging as a naturally artificial rebel.

ABSTRACT The aim of this article is to determine whether genetic engineering is ever acceptable. The prominent arguments which have been put forward by the opponents of genetic engineering are examined and evaluated. The arguments ‘we should not interfere with nature’, ‘we should not alter the genetic constitution of organisms’, and ‘we should not alter the genetic constitution of organisms to this extent’are found to be inadequate as valid arguments against all genetic engineering. However, it remains a possibility that there (...) is nothing intrinsically unethical about genetic engineering, but that the risks of misuse render the techniques ethically unacceptable. Since universal legislation is not possible, and the risks of genetic engineering are so real, this alone may be sufficient to dismiss all genetic engineering as wrong. (shrink)

Working with elders around the world has taught me that those living in grass huts in Africa with children at their feet are often happier than people in assisted‐living homes with a chandelier over their heads. My work in design consultancy and in fifteen years of running a nonprofit, Ibasho, that aims to co‐create socially integrated and sustainable communities that value their elders has allowed me to learn much about how architects and designers can contribute to helping people live a (...) good life in late life. People often need supportive services or other adaptations as they age, but do they really need—or want—the luxury environment few are accustomed to? The challenge for architects and designers is not to create a built environment whose carefully curated facades hide lives of quiet desperation. It is to help elders access the support they need without upending their lives or severing virtually all ties to their communities. (shrink)

There is a growing consensus that the offer of a reasonable compensation for oocyte donation for reproductive treatment is acceptable if it does not compromise voluntary and altruistically motivated donation. However, how to translate this ‘reasonable compensation’ in practice remains unclear as compensation rates offered to oocyte donors between different European Union countries vary significantly. Clinics involved in oocyte donation, as well as those in other medical contexts, might be encouraged in calculating a more consistent and transparent compensation for donors (...) if the elements that constitute a reasonable compensation are explicated. In doing so, lessons can be learnt from living organ donation and medical research participation. Practices in which the elements of a reasonable compensation for the individuals involved have already been more defined in the literature. By means of analogical reasoning, we will outline the different components of a reasonable compensation and subsequently apply these to the context of oocyte donation. We will argue that oocyte donors should first of all be reasonably reimbursed direct expenses related to the donation, without standard remuneration of lost wages. Second, donating oocytes requests a serious time investment, therefore donors are entitled to suitable compensation for their time spent and efforts made. Finally, we will explain that a reasonable compensation consisting of these two components allows for altruism to remain the key value of oocyte donation for reproductive treatment. However, if we acknowledge that donors’ motives are more complex and often include reasons from self-interest, the reasonable compensation may be complemented with modest (non)monetary benefits.

This article analyses the discourse of three prime ministers to explore how each leader identified the political self and constructed and promoted a particular relationship with the voter before the general elections. The outcome indicates the emergence of a new political communication style based on a partyconsumer. Whereas Aso's patronconsumer discourse of both Koizumi and Hatoyama demonstrates the entrepreneurial leadersconsumer model might have played a role in attracting a large number of unorganized voters to Koizumi in 2005 and in turn (...) to Hatoyama in 2009.

From ancient times, western civilization has been driven by a trust in scientific progress. Is Science Biology and biogenetics promise spectacular advances, mathematics unfolds new areas of understanding. This work explores some of the possible consequences for society and for the future of science itself.".

Dans le Littré, le mot « étudiant » est ainsi défini : « Celui qui étudie [...] / Particulièrement celui qui étudie dans une université, et, en France, dans une faculté [...] / Au féminin, étudiante, dans une espèce d'argot, grisette du Quartier Latin ». À la fin du XIXe siècle, l'étudiante, telle que nous la concevons aujourd'hui, c'est-à-dire celle qui étudie, n'existe pas. L'étudiante est celle qui accompagne, voire qui « couche » avec l'étudiant, et non celle qui étudie (...) à ses côtés.. (shrink)

In recounting some of the key sociological insights offered by over 30 years of research on emotion management, or emotion regulation, we orient our discussion around sociological answers to the following questions: What is emotion management? How does emotion management occur? Why does it occur? And what are its consequences or benefits? In this review, we argue that emotion and its management are profoundly social. Through daily interactions with others, individuals learn to differentiate which emotions are appropriate when, as well (...) as the most effective ways to bring their feelings in line with culturally agreed-upon emotion norms. Emotion management is also functional, not only for the individuals who perform it, but also for the dyads, groups, institutions, and societies in which they are embedded. The social processes through which individuals learn to display culturally appropriate emotions have important implications on many levels, from interpersonal interactions to the development of social movements.

This book compares the respective concepts of the law of nations put forward by the Spanish theologian Francisco Suárez and by the Dutch jurist Hugo Grotius. This comparison is based on the fact that both thinkers developed quite similar notions and were the first to depart from the Roman conception, which persisted throughout the entire Middle Ages and the early Renaissance. In Rome, jus gentium was a law that applied to foreigners within the Empire, and one which was often mistaken (...) for Natural Law itself. These two features can be found even in the works of writers such as Francisco de Vitória and Alberico Gentili. In Suárez and Grotius, the law of nations is applicable to an extra-national domain and inarguably becomes positive law. Yet, it also contains an ethical element that prevents it from transforming into a mere reflection of state interests. This work argues that this resemblance is hardly a coincidence: Grotius has read Suárez, and that influence has modified the foundations of his early thoughts on jus gentium. This should not be taken to imply that the Dutch jurist wasn't original: in both authors, the definition of the law of nations pursues his own internal logic. Nevertheless, Suárez's oeuvre allowed Grotius to solve a fundamental problem touched on in his early writings that had remained unanswered. Accordingly, his oeuvre promises to clarify one of the most significant moments in the History of International Law. (shrink)

Magnetoencephalography (MEG) and electroencephalography (EEG) are invaluable neuroscientific tools for unveiling human neural dynamics in three dimensions (space, time, and frequency), which are associated with a wide variety of perceptions, cognition, and actions. MEG/EEG also provides different categories of neuronal indices including activity magnitude, connectivity, and network properties along the three dimensions. In the last 20 years, interest has increased in inter-regional connectivity and complex network properties assessed by various sophisticated scientific analyses. We herein review the definition, computation, short history, (...) and pros and cons of connectivity and complex network (graph-theory) analyses applied to MEG/EEG signals. We briefly describe recent developments in source reconstruction algorithms essential for source-space connectivity and network analyses. Furthermore, we discuss a relatively novel approach used in MEG/EEG studies to examine the complex dynamics represented by human brain activity. The correct and effective use of these neuronal metrics provides a new insight into the multi-dimensional dynamics of the neural representations of various functions in the complex human brain.
