Objective: Atypical patterns of language lateralization due to early reorganizational processes constitute a challenge in the pre-surgical evaluation of patients with pharmaco-resistant epilepsy. There is no consensus on an optimal analysis method used for the identification of language dominance in MEG. This study examines the concordance between MEG source localization of beta power desynchronization and fMRI with regard to lateralization and localization of expressive and receptive language areas using a visual verb generation task.Methods: Twenty-five patients with pharmaco-resistant epilepsy, including six (...) patients with atypical language lateralization, and ten right-handed controls obtained MEG and fMRI language assessment. Fourteen patients additionally underwent the Wada test. We analyzed MEG beta power desynchronization in sensor (controls) and source space (patients and controls). Beta power decrease between 13 and 35 Hz was localized applying Dynamic Imaging of Coherent Sources Beamformer technique. Statistical inferences were grounded on cluster-based permutation testing for single subjects.Results: Event-related desynchronization of beta power in MEG was seen within the language-dominant frontal and temporal lobe and within the premotor cortex. Our analysis pipeline consistently yielded left language dominance with high laterality indices in controls. Language lateralization in MEG and Wada test agreed in all 14 patients for inferior frontal, temporal and pari... (shrink)

The supervisor of the activities of a system user should benefit from the knowledge contained in the event logs of the user. They allow the monitoring of the sequential and parallel user activities. To make event logs more accessible to the supervisor, we suggest a process mining approach, including first the design of an understanding model of the activities of a system user. The model design is based on the relationships between the event logs and the activities of a system (...) user. An intervention model completes the understanding model to assist the supervisor. The intervention model enables an action of the supervisor on the critical activities, and the detection of anomalies. The models are automatically designed with a model-driven engineering approach. An experiment on a smart home system illustrates this tooled design, where the supervisor is a medical or paramedical staff member. (shrink)

This title provides a synoptic overview of the current state of interdisciplinary research, education, administration and management, and problem solving - knowledge that spans the disciplines and interdisciplinary fields and crosses the space between the academic community and society at large.

This paper proposes to analyze the significant methodological adjustments which were brought to a collaborative research project in response to specific contextual constraints. The research issues which emerged from this context and led the research team to a methodological reconceptualization are presented along with the emerging methodological model. Outcomes of the methodological changes including participant empowerment, are discussed and lead the authors to postulate that an ecocollaborative approach, based upon horizontal relationships and taking into account the complexity of systems, appears (...) as a means to critically reevaluate teachers and researchers’ work in order to reduce institutional constraints, push back against limits to professional action, and consequently build a common emancipatory culture.

Background: Understanding is an important goal of the informed consent process in research. We sought to assess the interrater reliability (IRR) and concurrent validity of two measures of understanding in child and young adult subjects and their parents. Methods: We conducted a cross-sectional survey and interview-based study of children and young adults participating in a clinical trial for cancer, along with one parent per child or young adult subject. We estimated the IRR of the Semi-Structured Comprehension Interview (SSCI) and the (...) MacArthur Competence Assessment Tool for Clinical Research (MacCAT-CR). We also estimated concordance between the SSCI, the MacCAT-CR, and the Quality of Informed Consent (QuIC). Results: For our sample of 32 subjects (16 parent–child pairs), IRR estimates were high for total score on the SSCI (intraclass correlation coefficient [ICC] = 0.88, 95% confidence interval [CI] = 0.76–0.94), as well as on the understanding (ICC = 0.93, 95% CI = 0.86–0.97) and reasoning (ICC = 0.97, 95% CI = 0.94–0.98) subscales of the MacCAT-CR. IRR was lower for the appreciation subscale of the MacCAT-CR (ICC = 0.70, 95% CI = 0.47–0.84). Scores on the SSCI were strongly correlated with scores on the understanding subscale of the MacCAT-CR (Spearman's rho = 0.72, 95% CI = 0.48–0.85) and the QuIC (Spearman's rho = 0.66, 95% CI = 0.24–0.87). Mean administration time for the SSCI was 3.1 minutes (95% CI = 2.7–3.5 minutes). Conclusions: The SSCI is a valid and reliable measure of understanding for use with both pediatric and adult research participants. It is easy to administer and score consistently, even by nonprofessional raters. The SSCI is a promising tool for use by clinician-investigators to study, detect, and correct deficiencies in understanding among children, adolescents, and adults making decisions about research participation.

Tentant de rompre avec une représentation de la sérendipité comme produit du hasard et de la chance relatifs à « l’esprit scientifique », il s’agit ici d’analyser comment la sérendipité peut être le produit d’une concordance des « temporalités de champs » résultant d’une combinatoire de temps d’habitus, d’activité et d’institution propres à chaque champ. Ces temporalités de champs rythmant leurs luttes pour le monopole de la pratique scientifique, elles constituent un point de concordance entre champs à partir desquels s’agencent (...) les conditions de production et d’identification d’une découverte « par sérendipité ». Une telle approche a, au reste, l’avantage de combler un point aveugle de la littérature sociologique et de proposer une analyse structuraliste du processus de découverte scientifique permettant de l’appréhender comme « pratique coordonnée d’institution ».

This article discusses the discourses of disability through a parallel `disabling' of its own text. It draws on literary as well as sociological sources in order to interrogate the nature and relations of the `tragic', the `heroic' and the `comic'. The authors offer the conclusion that the comic is never quite absent from the discourse of tragedy (after Kundera), and turn that insight back on their own text, in an attempt to refuse the solemnities and closures of their own narrative.

The rediscovery of Aristotle’s works on syllogisms in the Latin world, especially the Sophistici Elenchi and then the Prior Analytics, gave rise to sophisticated views on the nature of syllogistic form and syllogistic matter in the thirteenth century. It led to debates on the ontology of the syllogism as studied in the Prior Analytics, i.e. the syllogism made of letters and the four logical constants a/e/i/o, with deep consequences on the definition of logic as a universal method for all sciences (...) and as a science itself.

Discrete supposition occurs whenever a discrete term, such as ‘Socrates‘, is the subject of a given proposition. I propose to examine this apparently simple notion. I shall draw attention to the incongruity, within a general theory of the semantic variation of terms in a propositional context, of the notion of discrete supposition, in which a term usually has a single semantic correlate. The incongruity comes to the fore in those treatises that attempt to describe discrete supposition as a sort of (...) personal supposition, although the same term cannot be in simple supposition in another propositional context, because it has no significate distinct from its suppositum. This shows a fundamental link between common signification, simple supposition and predicability, three notions that rely on the existence of a significate distinct and independent from the suppositum of the term. The connection is to be seen especially in William of Sherwood’s Introductiones, the only author of a terminist Summa who recognizes the existence of simple supposition for discrete terms. (shrink)

Dans cet article, nous nous concentrons sur les réflexions qu’Antoine Arnauld et Pierre Nicole consacrent au concept de « pensées imperceptibles », en soulignant à quel point ces réflexions sont liées à leur doctrine de la grâce et de la condition postlapsaire.

En particulier, les préjugés de nos penseurs sur les capacités intellectuelles des non-Européens ne sont pas extérieurs (...) à ce débat mais en sont, au contraire, le moteur. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Personal Narratives: Parenting Children With Autism Spectrum Disorders Through the Transition to AdulthoodCatherine Cornell, Julie Herren, Susan Osborne, and Kelly WeissTransition years: From Learning, Living and Loving to Maintenance and MediocrityCatherine CornellWhat does every parent of an autistic child worry about the most? For those of us with severely affected children, the answer to that question is: “Who will care for my child and keep her safe when (...) I am gone?”I drove my daughter back to her “group home” for a scheduled drop off on Saturday. There was only one car in the driveway and the house van was gone. Lily was not happy about returning “home.” Agitated, she opened the door to the car, almost before it was stopped, ran to the back of the house, and up the fire escape stairs to the door of her third floor bathroom, as if she was avoiding going through the main living rooms of the house. I called up to her that there was no one at home and she came back down and pushed through the unlocked door. Racing ahead of me, she was already shed of her clothes and in the shower: her self–calming method that she used whenever returning to the house. Thirty minutes later, after three attempts to leave the shower and throwing up in the shower, she dressed and ran back out to our car. I played her favorite music, attempting to calm her anxiety. This transition, from home to “group home,” was increasingly difficult due to recent changes in staff and housemates. Having no one there to greet her was ratcheting up the anxiety level for both of us.When the on–call manager came, Lily was so distraught that I asked for her medications and took her back home with me. Two days later she was calm enough and I was reassured enough to return her to the house. Somehow the house manager made the incident my fault. Perhaps I did react strongly, but on reflection, what triggered the strong reaction in me was the insecurity I felt at finding no one home. It seemed like a breach of trust. Like we were left, abandoned, our plans shattered and at the mercy of fate. Strong emotions for a little mix–up in communications (if that is what it was) but, nevertheless, there it is—how I felt and more to the point how my daughter felt.I relate this story because it illustrates what has changed the most about our lives since Lily left her school and entered the world of adult services: missing is the feeling of trust and security that responsible caring people would keep Lily safe when my husband and I cannot.My 25–year–old daughter Lily has severe autism. She was the most beautiful and easy baby imaginable and appeared to develop normally until she began to lose speech and have night terrors at 15 months of age. She was diagnosed initially with atypical autism, then pervasive developmental disorder not otherwise specified, and finally with autism at age four.From age four to twenty–two, she attended a specialized school for autism where she received age level academics, therapies for speech, and training in self–care and independent living. She did not do well in academics nor did she regain her lost speech. She did learn to care for herself with assistance and, as important, she gained social and behavioral skills and learned to live with others in a social way. She [End Page E1] also learned recreational and vocational skills that would be transferrable to the community, such as bicycle riding, rollerblading, swimming and jogging. The philosophy of her school was to build self–esteem and confidence by teaching music, art and physical skills—in small steps, ensuring success, and then building on those skills.In her last year at school, Lily was a happy and well–adjusted member of her small group of five young women living in a town house with support from trained school staff. She participated in job programs, earning money by recycling and working for Meals–On–Wheels. She went out into the community with her group... (shrink)

Abstract:Given the distinctiveness of its urban and civic spaces and of the famously strong but also complex sense of civic identity among its populace, sixteenth century Venice is a prime case study for applying spatial thinking when imagining the deliberate construction of space and the relationship of inhabitants to that space; in particular, the relationship between those in power and those without power as indicative throughout the cityscape. The formation and development of central features of Venetian urban space and identity, (...) since maritime topography constrained its urban space, created an unusually cohesive sense of civic identity linked to mythic historical memory. Looking through an interdisciplinary lens, theories of space offer a conceptual framework for imagining how the Venetian cityscape was created and evolved into one of the most diverse and unique cityscapes in the sixteenth century.

When the Argonauts reach the island of Lemnos, Apollonius of Rhodes tells us, they send their herald Aethalides to the ruler of the island. Such a means of establishing contact and requesting safe passage was the norm in the Homeric world; there heralds acted as intermediaries between commanders and subordinates or between groups of people. In preliterate societies, heralds facilitated communication: messages were transmitted through memorization and repetition rather than by means of writing. While verbatim repetition was no doubt a (...) necessary feature of this form of communication, its wholesale transference into Homeric poetry was not necessarily the logical corollary. Nonetheless, we know of such repetitions precisely because of their appearance in the Homeric poems. It is now widely accepted that such passages are a result of the oral style of composition in which the oral poet repeats passages just as he uses shorter formulaic phrases. The debate embedded in the A-scholia of the Iliad suggests that repeated passages were a source of contention already in antiquity. While it is more common to see the scholiasts trying to decide which passage is ‘correct’ and which should be athetized, this provides evidence that athetization was not a unanimous impulse. The scholiast defends 2.60–71, part of which is repeated for the third time, against Zenodotus. (shrink)

The literature of the past century produced an historical reconstruction of statics theory applied to mechanical structures coinciding–starting with Le Mecaniche (1634) and Discorsi e dimostrazioni matematiche sopra a due nuove scienze (1638) by Galileo Galilei (1564–1642). Based on previous research (RP) and our historical and historiographical line of research [37], in this paper we briefly analyse Buonaiuto Lorini (1540–1611) Le Fortificationi ([1596] 1609) as a bridge between the science of weights and early mechanical science, including the graphical scale and (...) machines. This is a fundamental and advanced military fortification–engineering treatise with an evident important relationship between theory & practice, including designs–projects of both fortresses and machines, understood as tools, to manufacture them. Lorini also presents an excursus on how fortifications developed according to the advent of new artillery/weapons, comprising the crucial passage from the use of square to circular towers up to the description of modern fortresses in all their details, e.g., bulwarks and cavaliers, curtains, orillons, star–shaped plans. Basing on Archimedes’ (fl. 287–212 BCE) techniques (law of the lever) and Guidobaldo del Monte's (1545–1607; Le Mecaniche (1577–1581) he successfully engaged in advanced mechanical considerations. His position (at the end of the first chapter) on the distinction between the mathematician (scientist) and the mechanician (architect–engineer or even machine expert) is historiographically very interesting within the difference between abstract Euclidean geometry and the application of its contents to imperfect and heterogeneous reality. The translations are ours. (shrink)

The field of nanotechnology and nanoscience is growing rapidly in many areas of research, from electronics to biomedicine to material science. Carbon nanotubes are receiving a lot of attention in the research due to their unique properties and many possible applications. This new material is a good example of how nanotechnology provides us with new opportunities, but at the same time leaves us a lot of unknowns to deal with. In order to deal with the unknowns we need to consider (...) both the science and the ethics of the different applications of this novel material. Nanoethics is the study of the ethical issues in nanotechnology. It is a relatively new field of study and a lot of different methods have been suggested in this area. In this article a method is suggested combining an existing ethical theory with a practical approach in order to do a case study of the ethical considerations of using carbon nanotubes in biomedicine. For the case study to be of practical significance the scientific characteristics and properties of carbon nanotubes are reviewed to give the reader an overview of the research field. (shrink)

During the education of scientists at the university level the students become more and more specialized. The specialization of the students is a consequence of the scientific research becoming specialized as well. In the interdisciplinary field of nanoscience the importance of specialization is also emphasized throughout the education. Being an interdisciplinary field of study the specialization in this area is not focused on scientific disciplines, but on the different branches of the research. Historically ethics has not been a priority in (...) science education, however, in recent years the importance of such teachings has been highly recognize especially in medicine, biotechnology and engineering. The rapid development, the many new and unknown areas and the highly specialized focus of nanotechnology suggest the importance of having ethically competent researchers. In this article the importance of ethical competence in nanoscience research is argued for by an example of a dilemma that could occur in a research project. The dilemma is analyzed using two different ethical views, generating two different choices for action. It is seen that the dilemma can have more than one solution and that ethical competence can help in justifying the choice of solution in a specific situation. Furthermore it is suggested that a way to reach this competence is through education in ethics incorporated into the nanoscience education curriculum. (shrink)

The U.S. Supreme Court recently held that a parody by the rap group 2 Live Crew of Ray Orbison's song "Oh, Pretty Woman" was "fair use" and thus did not infringe the copyright. Although the court insisted that it was not evaluating the quality of the parody, I argue that it does in fact make several aesthetic evaluations and sometimes even seems to praise the content of the parody. I first consider the stated reasons for the claimed refusal of the (...) court to evaluate aesthetic quality. Second, I examine the evaluations which the court in fact does make, at least some of which are clearly aesthetic evaluations. I then argue that aesthetic value judgments are both necessary and possible for determinations of "fair use" for such works as the "Pretty Woman" parody. (shrink)

We argue that the post-9/11 environment has amounted to a substantive change in the longstanding United States relationship with the international human rights regime. We identify three distinct phases of that relationship, noting that in the most recent phase, since 9/11, the US has moved from passive support of the international human rights regime to a direct attack of that regime. Realist and liberal regime theories suggest that the human rights regime is relatively weak, and is unlikely to withstand such (...) an attack. We find that the regime has not only continued to persist, but has flourished even as US support has faltered. The human rights regime is surprisingly strong. We argue it is the ideological nature of the regime that explains its resilience, which suggests that constructivist theory is necessary to fully understand the human rights regime. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Aesthetics in Feminist PerspectiveJulie Van CampAesthetics in Feminist Perspective, edited by Hilde Hein and Carolyn Korsmeyer; xv & 252 pp. Bloomington: Indiana University Press, 1993, $39.95 cloth, $14.95 paper.Has feminism been hijacked by one lock-step agenda, suppressing all dialogue and debate? Far from it, judging from this collection of seventeen essays on feminist aesthetics. The first such collection in English, it includes eleven essays previously published in Hypatia (...) (1990).This well-organized volume offers both broad theoretical considerations and applications to specific art forms, diverse methodological perspectives, and healthy debate among the contributors. The section on “The Nature of Art: Some Feminist Alternatives” considers feminist perspectives as alternatives to traditional concepts of art, motivated by considerations of the art of women. Skepticism abounds in the section on “Interpretation and Point of View” concerning a “universal” or “paradigmatic” female voice in literature, film, and visual art. “Philosophical and Critical Legacies” reveals diverse feminist readings of Kant, Nietzsche, Cartesian metaphysics, and postmodernism.Co-editor Hilde Hein proposes that aesthetics provides a promising road map for feminist philosophy and indeed philosophy generally. Aesthetics has learned to reject foundationalism and essentialism in favor of pluralism, a necessity in the face of the astonishing diversity and ever-changing landscape in contemporary art. This theoretical transition in aesthetics shows how philosophy could fruitfully shed the false security of essentialism to embrace the sometimes raucous pluralism of methods, races, cultures, and genders assaulting all humanities disciplines in recent decades. As co-editor Carolyn Korsmeyer notes, feminist scholarship challenges “the mask of universality and gender-neutrality” (p. vii). [End Page 178]The myth that feminist scholarship is merely thinly veiled political action, devoid of intellectual integrity, is shattered by this collection. Well-represented is the diversity of analytic and European methodologies that enrich contemporary philosophical dialogue. Many of the articles scrutinize the nature of “feminism” itself, as well as appropriate methodologies and questions. The interdisciplinarity of feminist research also is in welcome evidence, with seven essays by scholars from English, African-American studies, music, and psychology.Should feminist art and aesthetics be “nondominative”? Should it “endorse” female experience? Do proposals for “ideal” feminist artistic expression inadvertently retreat to the essentialism and uniformity that feminists have sought to dispel? Should feminists reject the tradition of “formalism” in favor of an approach that re-integrates art with the community and the concerns of daily life? This perspective is widespread today in postmodern thought, but feminist considerations bolster the case made elsewhere for the fall of the so-called elite object.Are there distinctive features that mark the work of female artists, such as group participation, rather than performances for passive audiences? This feature is pervasive in contemporary art, from the happenings of Andy Warhol in the 1960s to the “Messiah” sing-alongs popular for decades. Is feminist art marked by a melding of aesthetic and erotic elements? Surely that is also a trait of the art of most cultures, by men as well as women.These explorations reveal a paradox in today’s feminism. In highlighting female traits (such as the virtues of being caring and nondominating), are women being celebrated, liberated, and freed? Or are they frozen into roles which not all women consider their most important attributes as persons?Female artists and theorists deserve enormous credit for encouraging a re-thinking of the ways in which art is created and understood, but many other forces drive these developments as well. Indeed, some of the harshest critics of analytic philosophy are analytic philosophers steeped in that tradition, both male and female. It seems a pointless chicken-and-egg exercise to wonder if feminists caused this re-thinking or were one of several groups in a happy confluence of re-examination from various perspectives. Fortunately, the issue need not be resolved for scholars and students to appreciate this outstanding volume.Julie Van CampCalifornia State University, Long BeachCopyright © 1995 The Johns Hopkins University Press...

Motivated by the significant amount of successful collaborative problem solving activity on the Web, we ask: Can the accumulated information propagation behavior on the Web be conceived as a giant machine, and reasoned about accordingly? In this paper we elaborate a thesis about the computational capability embodied in information sharing activities that happen on the Web, which we term socio-technical computation, reflecting not only explicitly conditional activities but also the organic potential residing in information on the Web.

A new layer of complexity, constituted of networks of information token recurrence, has been identified in socio-technical systems such as the Wikipedia online community and the Zooniverse citizen science platform. The identification of this complexity reveals that our current understanding of the actual structure of those systems, and consequently the structure of the entire World Wide Web, is incomplete, which raises novel questions for data science research but also from the perspective of social epistemology. Here we establish the principled foundations (...) and practical advantages of analyzing information diffusion within and across Web systems with Transcendental Information Cascades, and outline resulting directions for future study in the area of socio-technical systems. We also suggest that Transcendental Information Cascades may be applicable to any kind of time-evolving system that can be observed using digital technologies, and that the structures found in such systems comprise properties common to all naturally occurring complex systems.

Past research finds that after menopause some women experience negative changes such as vaginal dryness, decreased libido, and decreased orgasm quality; very little research inquires about positive changes. In contrast, this study shifts the research focus from whether women experience menopausal changes to how women view any changes in sex life. Based on 30 in-depth interviews with heterosexual and lesbian women, the author finds that most women emphasize cultural and social issues, such as relationship status and quality, health, and sexual (...) history, rather than menopausal changes when they describe sex after menopause. However, she finds a difference by sexual orientation in how women handle problems in sex. The author concludes by discussing the implication of this research for future menopause and sex research; most important, she emphasizes studying sex in the context of women's lives rather than as a result of the biological changes of menopause.

This article examines the implications of the Deleuzian concept of `nomad thought' within the context of postcoloniality and indigenous politics. I argue that Deleuze's deconstruction of coherent and self-identical subjectivity through this concept disallows the possibility of effective indigenous politics through its lack of accountability to a `politics of location', its implicit reproduction of a universalized western subject, and its delegitimation of `experience' and `local knowledge'. I investigate these dynamics in Deleuze's work, and also in deployments of the Deleuzian figure (...) of the nomad and of `nomad thought' by Rosi Braidotti and Paul Patton. As a counterpoint to Deleuze, I discuss a number of feminist and postcolonial writers who recuperate concepts such as `experience' and `local knowledge', yet without lapsing into essentializing discourses. Their work enables robust versions of indigenous politics, and it is by adopting such approaches that feminist and postcolonial theory can move forward in politically accountable ways. (shrink)

Upshot: Albeit mostly supportive of our work, the commentaries we received highlighted a few points that deserve additional explanation, with regard to the notion of learning in our model, the relationship between our model and the brain, as well as the notion of anticipation. This open discussion emphasizes the need for toy computer models, to fuel theoretical discussion and prevent business-as-usual from getting in the way of new ideas.
