The multi‐allelic self‐incompatibility polymorphisms in angiosperms have long interested geneticists and population geneticists, but the limits of classical genetic resolution were reached many years ago. In recent years, new progress has been made by molecular genetic approaches. Intriguing similarities to and differences from the fungal systems are emerging. The polymorphism at these loci is now known to be even more baroque than appeared from classical genetic studies. Alleles differ so much at the level of both the DNA and protein sequence (...) that they would be difficult to recognise as products of the same locus, were it not for the presence of certain conserved regions. Despite the successes of the recent work, the locus responsible for the specificity of the incompatibility reaction in pollen, and the mechanism of self‐incompatibility, remain elusive. (shrink)

Changes in breeding system are a regular evolutionary change in plants, as self‐fertilisation is often advantageous, particularly for weedy and colonising species. The adoption of Arabidopsis thaliana as a plant model species has led to interest in how self‐incompatibility was lost so that this species became highly inbreeding. Molecular evolutionary approaches have recently focused on investigating two loci involved in the incompatibility recognition process in related Arabidopsis species; non‐functional copies of these genes still exist in A. thaliana. New work studying (...) polymorphism at these loci found strikingly low diversity at one of them, suggesting that spread of a mutation in this gene might have caused self‐compatibility in an ancestor of A. thaliana.1 However, it is difficult to be sure of the time when the selfing habit evolved in the lineage that led to A. thaliana BioEssays 27:472–476, 2005. © 2005 Wiley Periodicals, Inc.

Theodor W. Adorno and Jürgen Habermas both champion the goal of a rational society. However, they differ significantly about what this society should look like and how best to achieve it. Exploring the premises shared by both critical theorists, along with their profound disagreements about social conditions today, this book defends Adorno against Habermas' influential criticisms of his account of Western society and prospects for achieving reasonable conditions of human life. The book begins with an overview of these critical theories (...) of Western society. Both Adorno and Habermas follow Georg Lukács when they argue that domination consists in the reifying extension of a calculating, rationalizing form of thought to all areas of human life. Their views about reification are discussed in the second chapter. In chapter three the author explores their conflicting accounts of the historical emergence and development of the type of rationality now prevalent in the West. Since Adorno and Habermas claim to have a critical purchase on reified social life, the critical leverage of their theories is assessed in chapter four. The final chapter deals with their opposing views about what a rational society would look like, as well as their claims about the prospects for establishing such a society. Adorno, Habermas and the Search for a Rational Society will be essential reading for students and researchers of critical theory, political theory and the work of Adorno and Habermas. (shrink)

Recent discussions of rational deliberation in science present us with two extremes: unbounded optimism and sober pessimism. Helen Longino (1990) sees rational deliberation as the foundation of scientific objectivity. Miriam Solomon (1991) thinks it is overrated. Indeed, she has recently argued (2006) that group deliberation is detrimental to empirical success because it often involves groupthink and the suppression of dissent. But we need not embrace either extreme. To determine the value of rational deliberation we need to look more closely at (...) the practice and practitioners of science. I offer a closer look here by exploring the joint agency of small research teams. Although there are factors that contribute to the suppression of dissent in group contexts, a closer look at the literature on group dynamics suggests that there are ways to mitigate the effects of groupthink. Thus, there is reason to be cautiously optimistic about the value of rational deliberation within certain scientific contexts. (shrink)

Throughout his work, Adorno contrasted liberal ideology to the newer and more pernicious form of ideology found in positivism. The paper explores the philosophical basis for Adorno's contrast between liberal and positivist ideology. In Negative Dialectics, Adorno describes all ideology as identity-thinking. However, on his view, liberal ideology represents a more rational form of identity-thinking. Fearing that positivism might obliterate our capacity to distinguish between what is and what ought to be, Adorno sought a more secure foundation for his critique (...) of existing conditions. He found this basis in liberal discourse. In the concept of freedom, for example, Adorno located ideas or ideals that negate and transcend the given. One of the conditions for the possibility of critical thought lies in such ideas; critical thinking consists in wielding the more emphatic content of concepts against the pathic rationality of existing conditions. Far from prescribing mimesis as the antidote to a damaged social, political and economic reality, then, Adorno advocates a more dialectically inflected use of concepts as the basis for social criticism. Key Words: Adorno • Critique • Identity • Ideology • Liberalism • Positivism. (shrink)

Despite eschewing the utility of ends or purposes in natural philosophy, Descartes frequently engages in functional explanation, which many have assumed is an essentially teleological form of explanation. This article considers the consistency of Descartes's appeal to natural functions, advancing the idea that he is utilizing a non-normative, non-teleological form of functional explanation. It will be argued that Cartesian functional analysis resembles modern causal functional analysis, and yet, by emphasizing the interdependency of parts of biological systems, is able to avoid (...) many of the problems attendant upon modern causal theories. It is for this reason, if no other, that the study of Descartes's natural philosophy should be of interest to contemporary theorists of functional analysis. (shrink)

In determining when sexual behavior in the workplace creates a hostile working environment, some courts have asked, Would a reasonableperson view this as a hostile environment? Two recent court decisions, recognizing male-female differences in the perception of social sexual behavior at work, modified this standard to ask, Would a reasonablevictim view this as a hostile environment? As yet, there is no consensus in the legal community regarding which of these standards is just.We propose that moral theory provides the framework from (...) which business people can construct just procedures regarding sexually hostile environments. We argue that the natural duty of mutual respect of persons and the natural duty not to harm the innocent compels business people to identify sexually hostile work environments from the perspective of the reasonable victim, usually from the woman's perspective.

Seventeenth-century natural-law philosophers participated in colonizing and slave-trading companies, yet they discussed slavery as an abstraction. This dispassionate approach is commonly explained with the “distance thesis” that the practice of slavery was at some remove from Northwest Europe. I contest the thesis, with a specific focus on pre-Restoration English discourse and Hobbes's political theory. By laying out the salient context — English experience of Barbary-coast slavery and an inherited neo-Roman intellectual frame — I argue, first, that slavery was hardly a (...) distant phenomenon and, second, that Hobbes's discussion of slavery expressed ideas familiar in ordinary discourse. The conclusion contrasts the English neo-Roman outlook with Spanish neo-Aristotelianism. (shrink)

Various studies have shown that philosophizing with children at school can have a positive effect on cognitive, language and social skills. However, previous studies have not considered how the quality of the dialogue influences these outcomes. Addressing this gap, our article introduces a high-inference rating instrument to assess the quality of philosophical dialogue. This instrument features four quality dimensions: Philosophical Richness, Co-construction, Focus, and Restrained Facilitation. It was applied to evaluate 63 class dialogues from a Swiss study involving secondary-school students. (...) The article presents the instrument using excerpts from the study, along with initial validation information, showing its reliability in measuring philosophical dialogue quality. The significance of this research lies in its focus on the quality of philosophical dialogue, an aspect often overlooked in educational settings. By providing a tool to assess this quality, we open up new pathways for analyzing the effectiveness of philosophical dialogues in schools. This is especially relevant as educational systems increasingly recognize the importance of developing students' critical thinking and discussion skills. The findings highlight the potential of high-quality philosophical dialogues to enrich students' educational experiences and offer insights for educators and researchers into enhancing these interactions. This study contributes to a deeper understanding of how philosophical dialogue can be used as a powerful educational tool, not just for engaging students but for fostering meaningful and impactful learning.

Since their introduction about ten years ago the rapid methods for sequencing DNA based either on selective chemical degradation1 or primed enzymatic synthesis2 have been subject to a number of modifications and improvements.3, 4 Two recently published papers describe further advances in these technologies: a method for obtaining information about DNA sequences directly from uncloned mammalian genomic DNA5 and a possible first step towards the automation of DNA sequencing6.

This article presents a conceptual approach to feminist history that focuses on the strategies activists use in different temporal and spatial locations. The argument builds on recent insights within feminist theory and historiography that reveal an intimate relationship between historiography and epistemology in knowledge politics. This article, however, probes the limitations of this relationship by focusing on how current historiographical methods exclude or dilute the actions and events of history through representation and citation. By examining the work of Jamaican theatre (...) collective Sistren, and Bristol agit-prop group Sistershow, the article presents two ways to rethink temporality that makes those histories resistant to representation. This article argues for a more careful historiography that can do justice to the action of different historical temporalities. In the process, it opens emergent spaces and temporal challenges for feminist knowledge politics. (shrink)

The social construction of the individual is a central theme in critical social theory. Theodor W. Adorno and Michel Foucault address this theme throughout their work, offering important insights into individual identity and autonomy in the West. For Adorno, of course, individuation can be fully understood only with the aid of Freudian theory. However, since Foucault often criticized psychoanalysis, the paper will begin by comparing Adorno’s and Foucault’s positions on Freud’s theories of instinct and repression. Following this discussion, I shall (...) examine Adorno’s and Foucault’s distinct views on domination, comparing individuation as an effect of exchange relations in Adorno and of power relations in Foucault. This comparison will issue in a consideration of precisely what is being shaped into an individual. The final section of the paper will draw conclusions about the central features of individuation, while broaching the problem of whether power relations and exchange relations are now so powerful that resistance to them is effectively futile.

“Nature, Red in Tooth and Claw” explores Adorno’s ideas about our mediated relationship with nature. The first section of the paper examines the epistemological significance of his thesis about the preponderance of the object while describing the Kantian features in his notion of mediation. Adorno’s conception of nature will also be examined in the context of a review of J. M. Bernstein’s and Fredric Jameson’s attempts to characterize it. The second section of the paper deals with Adorno’s Freudian account of (...) internal nature. While arguing against Joel Whitebook’s view that Adorno needs a concept of sublimation, I contend that Adorno’s genetic account of the relationship between nature and mind enables him to respond to the Freudian injunction to displace the id with the ego with a view to fostering autonomy. In the final section of the paper, problems with Adorno’s ideas about external and internal nature are briefly discussed. (shrink)

Being empathetic (or compassionate) is an important trait that allows for those working in health care professions to successfully analyze cases and provide patients with adequate care. One standard and enormously important way to try and teach empathy involves the use of case studies. The case-study approach, however, has some unique limitations in teaching empathy. This paper describes an activity where students are asked to imagine that they have contracted a specific disease (one that lasts the entire semester) through a (...) process of random (or lottery) assignment. Having contracted a disease, students are then tasked with taking on the persona of that patient. In writing and adopting the perspective of that patient, students are better able to learn the kind of empathy needed to be a successful health care professional. (shrink)

Suppose that one of us were to think as if he was suddenly created and complete but with his view obscured so that he could not see outside. And suppose that he had been so created as if he were moved in the air or the void in such a way that he was not touched by the thickness of the air that he would be able to sense it and as if his limbs were separated so that they did (...) not touch either him or each other. Thence he should see if he would affirm being of his essence. He will not hesitate to affirm himself to exist. He will not however affirm things exterior to his members nor the hidden things of his interiors nor his soul nor his brain nor anything else extrinsic. He will affirm himself to exist though he will not affirm the length or the width or the thickness of himself. If however in that period of time it is possible for him to imagine a hand or another member, that would not be imagined to be part of him nor necessary to his essence. (shrink)

In this systematic review, we aim to describe the association between temporal lobe epilepsy and sleep, with bidirectional links in mechanisms and therapeutic aspects. Sleep stages may variably impact seizure occurrence, secondary generalization and the development, frequency and distribution of interictal epileptiform discharges. Conversely, epilepsy affects sleep micro- and macroarchitecture. TLE, the most frequent form of drug resistant epilepsy, shares an enduring relationship with sleep, with some intriguing potential mechanisms specific to anatomic localization, linking the two. Sleep characteristics of TLE (...) may also inform localizing properties in persons with DRE, since seizures arising from the temporal lobe seem to be more common during wakefulness, compared to seizures of extratemporal origin. Polysomnographic studies indicate that persons with TLE may experience excessive daytime somnolence, disrupted sleep architecture, increased wake after sleep onset, frequent shifts in sleep stages, lower sleep efficiency, decreased rapid eye movement sleep, and possibly, increased incidence of sleep apnea. Limited literature suggests that effective epilepsy surgery may remedy many of these objective and subjective sleep-related concerns, via multipronged effects, apart from reduced seizure frequency. Additionally, sleep abnormalities also seem to influence memory, language and cognitive-executive function in both medically controlled and refractory TLE. Another aspect of the relationship pertains to anti-seizure medications, which may contribute significantly to sleep characteristics and abnormalities in persons with TLE. Literature focused on specific aspects of TLE and sleep is limited, and heterogeneous. Future investigations are essential to understand the pathogenetic mechanisms linking sleep abnormalities on epilepsy outcomes in the important sub-population of TLE. (shrink)

The preceding symposium articles speculate on the psychosocial dynamics of discrimination as reverberating with grief, mourning, melancholia, and denial. They invite a psychoanalytic paradox on the fate of inchoate loss and its complex relation to oppression and depression: constellations of attachment to loss met with its social and psychical disavowal render inexpressible to the other the work of mourning and drive its myriad expressions. A different way of putting the dilemma is that grief calls upon symbolic equation and the pain (...) of symbolization. Deborah Britzman's coda reads the psychoanalyst Melanie Klein's consideration of depression as the origin of the human condition with Paulo Freire's call to educators for a radical humanization to release oppression. Between Freire's Pedagogy of the Oppressed and Klein's Love, Guilt, and Reparation, the coda traces a signifying loss that attests to the entwined roots of the self/other matrix with attention to the needed fluctuations within interiority and exteriority, loss and the depressive position, illness and health, and psychoanalysis with pedagogy.

The extensive literature on the Learning Organisation proposes that a competitive advantage can be achieved through the systematised generation and application of knowledge. Consequently, much of the debate concerns the processes, routines and organisational features that a firm should adopt to learn more, and faster, than its competitors. Less attention is given to understanding the nature of the knowledge that is created by these Learning Organisations. We hold that the topic is more important than its current weight in the literature (...) because the performance claims of the models proposed critically depend upon the newly acquired knowledge replacing ignorance or knowledge with less utility. In this paper we explore the nature of knowledge that Learning Organisation theory seeks to create by articulating implicit epistemological assumptions found within the literature. We show that the capacities of each epistemology to help an organisation reject falsehood and make greater use of its knowledge are critically undermined by these very routines. The paper concludes by highlighting the importance of a sceptical epistemology and outlines a process that would strengthen doubting behaviour. (shrink)

This article relates the emergence of a group of faculty researchers utilizing complexity science approaches. The narrative emerges from three projects combining research into complexity, communities, and technologies. Details of how the research was initiated, and the nature and quality of the conversational method, are provided. In addition, theoretical concepts that were consciously applied and others that arose through insights from the data as it was collected are discussed. Although this is like most real narratives, a never-ending story, it concludes (...) with a presentation of some of the ideas that separate complexity-informed research from other paradigms.

This paper examines how significant musical moments, occurring within singular contexts, may be performative to the development of community. While community is often viewed within music education as an unequivocal good, I argue that this result may not always be beneficent. In this paper, I look at one unique performative moment through the lens of anti-racism education as the potential for community conceived as multicultural human subjectivity. Drawing upon the arguments of Theodore Adorno, Paul Gilroy, and others, I then examine (...) this same moment as one in which the seeds of fascistic community may also be sewn. From this background, I examine the ongoing project of the National Association for Music Education (MENC) known as the National Anthem Project (NAP) as an identity building project, questioning where the lines blur between solidarity, nationalism, and fascistic forms of community within the potentially significant musical moments that NAP may also foster.

As consequence to the coronavirus outbreak, governments around the world imposed drastic mitigation measures such as nationwide lockdowns. These measures included the closures of schools, hence, putting parents into the position of juggling school and work from home. In the present study, we investigated the well-being of parents with school-aged children and its connection to mitigation measures with particular focus on parental roles “caregiver,” “worker,” and “assistant teacher” as stressors. In addition to direct effects, we expected indirect effects on well-being (...) through changes in household dynamics. Data were collected via an online survey (N= 1313, 85.5% female; 53.2% university degree) conducted during the first wave of school closures in Germany. We observed that during the early COVID-19 pandemic, parental well-being in general was quite positive. Comparing the positive and negative PANAS subscales, parents agreed significantly more with the positive than with the negative items,t(1299) = 28.55,p< 0.001. Parents also reported an increase in positive family activities during the lockdown,t(1272) = 43.96,p< 0.001. Although a significant increase in negative household dynamics, such as disputes, was also observed to a lower extent,t(1295) = 7.78,p< 0.001. Using structural equation modeling, we observed that “homeoffice” was not significantly related to parents’ well-being, but positively affected household dynamics. Taking on the role of “assistant teacher” was negatively related to household dynamics. Additionally, we found a significant direct effect on negative affect for “assistant teacher.” We conclude that parents of school-aged children have mostly been able to establish positive dynamics in their households during the lockdown given the extra time they got to spend with their children by working from home. However, our results identify the role of “assistant teacher” as a potential stressor for parents. Bridging the gap between teachers and parents seems warranted especially if (some) distance-learning continues, in order to avoid long-term consequences for the students. (shrink)
