The notion of “the burden of proof” plays an important role in real-world argumentation contexts, in particular in law. It has also been given a central role in normative accounts of argumentation, and has been used to explain a range of classic argumentation fallacies. We argue that in law the goal is to make practical decisions whereas in critical discussion the goal is frequently simply to increase or decrease degree of belief in a proposition. In the latter case, it is (...) not necessarily important whether that degree of belief exceeds a particular threshold (e.g., ‘reasonable doubt’). We explore the consequences of this distinction for the role that the “burden of proof” has played in argumentation and in theories of fallacy. (shrink)

Brent Kious has recently attacked several arguments generally adduced to support anti-doping in sports, which are widely supported by the sports medicine fraternity, international sports federations, and international governments. We show that his attack does not succeed for a variety of reasons. First, it uses an overly inclusive definition of doping at odds with the WADA definition, which has global, if somewhat contentious, currency. Second, it seriously misconstrues the position it attacks, rendering the attack without force against a more balanced (...) construal of an anti-doping position. Third, it makes unwarranted appeals to matters Kious considers morally ‘clear’, while simultaneously attacking a position many others take to be equally morally ‘clear’, namely that of anti-doping. Such an inconsistency, attacking and appealing to the moral status quo as befits one’s argument, is not acceptable without further qualification. Fourth, his position suffers from a general methodological flaw of over-reliance upon argumentation by analogy. Moreover, it is argued that the analogies, being poorly selected and developed, fail to justify his conclusion that the anti-doping lobby lacks philosophical and moral authority for its stance. These issues are symptomatic of a more fundamental problem: any attempt at providing a blanket solution to the question of whether doping is morally acceptable or not is bound to run up against problems when applied to highly specific contexts. Thus, rather than reaching any particular conclusion for or against doping products or processes in this article, we conclude that an increased context-sensitivity will result in a more evenhanded appraisal of arguments on the matter.

The phenomenon of perceptual persistence after the motion stops in shape-from-motion displays was used to study the influence of prior knowledge on the maintenance of a percept in awareness. In SFM displays an object composed of discontinuous line segments are embedded in a background of randomly oriented lines. The object only becomes perceptible when the line segments that compose the object and the lines that compose the background move in counterphase. Critically, once the movement of the line segments stops, the (...) percept of the object persists for a short period of time. In the present study, perceptual persistence for digits exceeded that reported for nonsense shapes composed of the same line segments. This result is taken as evidence that the processes involved in the persistence of SFM, and therefore sustained perception, are sensitive to top-down influences. (shrink)

When experiencing personal distress, people usually expect their romantic partner to be supportive. However, when put in a situation to provide support, people may at times be struggling with issues of their own. This interdependent nature of dyadic coping interactions as well as potential spillover effects is mirrored in the state-of-the-art research method to behaviorally assess couple’s dyadic coping processes. This paradigm typically includes two videotaped 8-min dyadic coping conversations in which partners swap roles as sharer and support provider. Little (...) is known about how such dyadic coping interactions may feed back into one another, impacting the motivation and ability to be a responsive support provider. In three behavioral studies, we examined how sharers’ experiences may spill over to affect their own support provision in a subsequent dyadic coping interaction. We hypothesized that the extent to which sharers perceive their partner as responsive to their self-disclosure increases the quality of their own subsequent support provision, whereas sharers’ lingering negative affect reduces the quality of their own subsequent support provision. In line with our first hypothesis, perceived partner responsiveness predicted the provision of higher-quality support, though primarily as perceived by the partner. Sharers who perceived their partner to have been more responsive were somewhat more likely to subsequently engage in positive dyadic coping and were rated as more responsive by their partners. Negative dyadic coping behavior was unaffected. Evidence for our second hypothesis was mixed. While lingering negative affect did not affect positive dyadic coping behavior or perceived support, it did increase the chances of negative dyadic coping behavior. However, given the very low occurrences of negative affect and negative dyadic coping, these findings should be interpreted with caution. Taken together, these findings suggest that support interactions may feed back into one another, highlighting the complex and interdependent nature of dyadic coping. The strongest and most consistent findings concerned the spillover effect of perceived partner responsiveness on subsequent perceived support quality, speaking to the key role of believing that one’s partner is responsive to one’s needs in promoting healthy relationship functioning.

Whilst presenting a number of features that have been put forward to characterize modernity as a way of life and a social system, this entry suggests a dissident genealogy that reveals a hidden history of continuities and alternatives. It thereby problematizes the norms about periodization and the assumptions about the elaboration of a logos that underlie the concept of the modern. This approach to modernity as a complex of processes, institutions, subjectivities, and technologies challenges the more familiar history of linear (...) temporalities and progressive transformations. The fruitfulness of seeing modernity, as much as other historical periods, as hybrid assemblages in a state of flux is that it draws attention to the heterogeneity and processual nature of cultures and feeds into the possibility of the critique of the present.

In the model theory of modules the Ziegler spectrum, the space of indecomposable pure-injective modules, has played a key role. We investigate the possibility of defining a similar space in the context of G-sets where G is a group.

Bei Nietzsches Texten handelt es sich häufig um Reaktionen auf seine breitgestreuten Lektüren. Sein Lesen ist zugleich ein Schreiben, und es verläuft ebenso selektiv und assoziativ wie aneignend: So werden unter Nietzsches Hand etwa Lesefrüchte aus naturwissenschaftlichen Lexika ästhetischen Überlegungen einverleibt oder ethno-anthropologische Fachbücher im Kontext philosophiegeschichtlicher Einordnungsversuche zitiert. Die Interpretation von Nietzsches Schriften ist daher stets auf eine philologisch-differenzierte Quellenarbeit angewiesen, die zugleich auch philosophisch-hermeneutischen Ansprüchen genügt. Nur so findet die spezifische Gemengelage aus Eigenem und Fremdem in Nietzsches Texten (...) ebenso adäquate Berücksichtigung wie die Vielzahl der handschriftlichen Lesespuren in den bis heute erhaltenen Büchern aus seiner persönlichen Bibliothek. In einer Reihe von Überblicksdarstellungen und exemplarischen Fallstudien unternimmt es der Band, Nietzsche im Spiegel seiner Lektüren als äußerst produktiven wie kreativen Leser zu charakterisieren, dessen Voraussetzungsreichtum nicht überschätzt werden kann.

There is increased recognition of the importance of well-designed scholarship on how immigration status and policies impact migrants in the United States, including those who are unauthorized. Some researchers have looked to community-based and participatory methods to develop trust, place migrants’ voices at the forefront, and engage collaboratively in using research as a tool for social change. This article reviews three ethical ambiguities that emerged in the process of a series of participatory action research projects with migrants in the United (...) States, many of whom were unauthorized. Specifically, three themes are discussed: the tension between the human desire to respond to injustices, and the challenges of doing so in ways that recognize one’s privilege and power as an outsider and supports the migrants’ agency and autonomy; the complex definition, explanation, and dimensions of “risk”; and the complexity of using a methodology that prioritizes participants’ collective identity and community in the context of regulations that are designed primarily to protect individuals.

Current report assessed measurement reproducibility and reliability of magnetic resonance spectroscopy (1H-MRS) at 3 Tesla in left and right posterior insular, pregenual and anterior midcingulate subdivisions. 10 healthy male volunteers aged 20 to 30 years were tested on four different days, of which 9 were included in the data analysis. Intra- and inter-subject variability of myo-Inositol (mI), Creatine (Cre), Glutamate (glu), total-Choline (tCho), total-N-acetylaspartate (tNAA) and combined Glutamine-Glutamate (Glx) were calculated considering the influence of movement parameters, age, daytime of measurements (...) and tissue composition. Overall mean intra-subject variability revealed small mean coefficients of variation (CV) across the four regions: 5.3% in aMCC, 6.6% in pgACC, 7.3% in pIL and 8.2% in pIR. For all neurochemicals combined, mean inter-subject variability demonstrated mean CVs of 9.05% (aMCC), 8.84% (pgACC), 10.00% (pIL) and 10.55% (pIR). Head movement, tissue composition and day time revealed no significant explanatory variance contribution suggesting a negligible influence on data. A strong correlation between Cramer-Rao Lower Bounds (CRLB; a measure of fitting errors) and the mean intra-subject CV (r=0.799, p<0.001) outlined the importance of low CRLB in order to obtain robust and finally meaningful 1H-MRS measures. The present findings confirm 1H-MRS as a reliable tool to measure brain neurochemistry in small subregions of the human brain. (shrink)

This volume contains 17 articles on various aspects of Islamic thought in the Middle East and in Southeast Asia.

In the business world, one of the key challenges is how to survive in ever changing business environments and outperforming the competitors, while keeping the operational cost at minimum and profits at maximum level. In other words, this can be described as the problem of improving operational efficiency and reducing cost. Over the past few years due to global financial challenges, it has become even more important to improve the operational efficiency and reduce costs to survive through these tough conditions. (...) Like other successful implementations of Lean philosophy, especially in automobile, aerospace, steel and healthcare, it can be applied in cable manufacturing to achieve competitive, sustainable and profitable processes. The main focus of Lean philosophy is to create value for the stakeholders and end customers by reducing the non-value added activities or waste, and laying a strong foundation towards sustainable growth, by focusing on continuous process improvement. The overall philosophy provides a focused approach for continuous process improvement and the targeting of a variety of tools and methods to bring improvements. This paper presents case studies for Lean scheduling of manufacturing processes and exemplify how Lean scheduling processes allow organisations to maintain the continuous improvement philosophy. This paper also addresses the key elements of rescheduling processes i.e. how to schedule and when to schedule. Further, the paper will exemplify key benefits of Lean scheduling and how the Cable industry could benefit from the proposed approach. (shrink)

Robert Sibley examines how Watson, Grant, and Taylor found in Hegel the theoretical tools needed to respond to Canada's uncertain existence.

A complete collection of Frank Sibley's articles on philosophical aesthetics, this volume includes five, remarkable, hitherto unpublished papers written in Sibley's later years. It addresses many topics, among them the nature of aesthetic qualities versus non-aesthetic qualities, the relation of aesthetic description to aesthetic evaluation, the different levels of evaluation, and the objectivity of aesthetic judgement. The later papers constitute both a significant development of Sibley's individual approach to aesthetics, such as his discussion of the distinction between (...) attributive and predicative uses of adjectives and of the aesthetic significance of tastes and smells, a topic Sibley considered to be much neglected.

The potential of physical activity to improve our health has been the subject of extensive research [38]. The relationship between physical activity and well-being has prompted substantial interest from exercise psychologists in particular [3], and it seems, is generating increasing interest outside the academic community in healthcare policy and practice inter alia through GP referrals for exercise. Researchers in the field have benefited from a rich tradition within psychology that investigates subjective well-being and its antecedents [7]. We argue that the (...) exercise and health psychology research suffers from this intellectual ancestry specifically in the form of two significant conceptual limitations. First, short-term pleasure and enjoyment which are associated with exercise induced well-being may mask activities that are doing us no good or even harm us [18]. Second, focusing on pleasure entails unacceptable methodological reductionism which undermines the validity of such research by excluding other ways in which our well-being may be enhanced in non-hedonistic terms.

This paper addresses the possibility of measuring perceived usability in an absolute way. It studies the impact of the nature of the tasks performed in perceived software usability evaluation, using for this purpose the subjective evaluation of an application’s performance via the Software Usability Measurement Inventory (SUMI). The paper reports on the post-hoc analysis of data from a productivity study for testing the effect of changes in the graphical user interface (GUI) of a market leading drafting application. Even though one (...) would expect similar evaluations of an application’s usability for same releases, the analysis reveals that the output of this subjective appreciation is context sensitive and therefore mediated by the research design. Our study unmasked a significant interaction between the nature of the tasks used for the usability evaluation and how users evaluate the performance of this application. This interaction challenges the concept of absolute benchmarking in subjective usability evaluation, as some software evaluation methods aspire to provide, since subjective measurement of software quality will be affected most likely by the nature of the testing materials used for the evaluation.

Geographies of Exclusion identifies forms of social and spatial exclusion and subsequently examines the fate of knowledge of space and society which has been produced by members of excluded groups. Evaluating writing on urban society by women and black writers, David Sibley asks why such work is neglected by the academic establishment, suggesting that both the practices which result in the exclusion of minorities and those which result in the exclusion of knowledge have important implications for theory and method (...) in human geography. Drawing on a range of ideas from social anthropology, feminist theory, sociology, human geography and psychoanalysis, this book presents a fresh approach to geographical theory, highlighting the tendency of powerful groups to "purify" space and to view minorites as defiled and polluting, and exploring the nature of "difference" and the production of knowledge.

This paper explores the distinctive features of the critical agenda associated with the ‘Social Life of Methods’. I argue that although this perspective can be associated with the increasing interest, often associated with scholars in Science and Technology Studies, to reflect on how methods can become objects of inquiry, it also needs to be rooted in the current crisis of positivist methods. I identify the challenge for positivism in terms of the decreasing ability of its procedures to effectively organize increasingly (...) ‘lively’ sources of standardized data, which can now be assembled using aesthetic registers. In developing this argument, I dispute the idea that this development is due to historical shifts linked to the way that methodological devices are playing an increasingly significant role in contemporary social life, which might be argued by writers such as Thrift or Castells. I also argue that by opening up issues of method to the aesthetic, we also recast the relationship between theory and method, pointing to the exhaustion of a certain kind of cultural theory within the social sciences. I contextualize these issues by considering how methods are implicated in the intellectual differentiation between scientific and humanities expertise. Rather than conceiving the ‘Social Life of Methods’ in terms of the rise of instrumentalist modes of governance, it is preferable to place it within the dialectic of transparency and the relationship between the implicit and explicit. These issues are addressed through introducing the papers in the special issue. (shrink)

A recent article from Archives of Disease in Childhood outlined problems with the act of gaining child assent for research participation. However the arguments used in the article are incomplete or misguided. Rather than being harmful, assent should be seen as an ethically-appropriate way in which we can engage with the child about his participation in research. While additional clarification of the concept of assent is needed, the child's family context can provide us with a valuable guide to the way (...) we involve him in the decision-making process.

Are people rational? This question was central to Greek thought and has been at the heart of psychology and philosophy for millennia. This book provides a radical and controversial reappraisal of conventional wisdom in the psychology of reasoning, proposing that the Western conception of the mind as a logical system is flawed at the very outset. It argues that cognition should be understood in terms of probability theory, the calculus of uncertain reasoning, rather than in terms of logic, the calculus (...) of certain reasoning. (shrink)
