Like several other classes of hormones, the class of plant hormones called auxins exert myriad effects on cell development. While auxins are most noted for inducing cell elongation, they are also involved in cell division, cell differentiation, cell and organ polarity, and wound responsiveness. Consistent with this pleiotropy, is the recent identification of several putative auxin receptors that in theory could represent the primary elements of more than one auxin signal pathway leading to distinct responses or leading in parallel to (...) a single response. Our current working hypothesis is that some auxin‐mediated responses may be mediated by multiple receptors. We describe some of what is known about each of the new putative receptors and elaborate on the hypothesis using the example of cell elongation. Specifically for auxin‐induced elongation, we propose that two rapid events, specific gene transcription and cell wall acidification, are separately mediated by at least two receptors, acting in the nucleus and at the plasma membrane, respectively.

In recent years, educational institutions have started using the tools of commercial data analytics in higher education. By gathering information about students as they navigate campus information systems, learning analytics “uses analytic techniques to help target instructional, curricular, and support resources” to examine student learning behaviors and change students’ learning environments. As a result, the information educators and educational institutions have at their disposal is no longer demarcated by course content and assessments, and old boundaries between information used for assessment (...) and information about how students live and work are blurring. Our goal in this paper is to provide a systematic discussion of the ways in which privacy and learning analytics conflict and to provide a framework for understanding those conflicts. -/- We argue that there are five crucial issues about student privacy that we must address in order to ensure that whatever the laudable goals and gains of learning analytics, they are commensurate with respecting students’ privacy and associated rights, including (but not limited to) autonomy interests. First, we argue that we must distinguish among different entities with respect to whom students have, or lack, privacy. Second, we argue that we need clear criteria for what information may justifiably be collected in the name of learning analytics. Third, we need to address whether purported consequences of learning analytics (e.g., better learning outcomes) are justified and what the distributions of those consequences are. Fourth, we argue that regardless of how robust the benefits of learning analytics turn out to be, students have important autonomy interests in how information about them is collected. Finally, we argue that it is an open question whether the goods that justify higher education are advanced by learning analytics, or whether collection of information actually runs counter to those goods.

“Big Data” and data analytics affect all of us. Data collection, analysis, and use on a large scale is an important and growing part of commerce, governance, communication, law enforcement, security, finance, medicine, and research. And the theme of this symposium, “Individual and Informational Privacy in the Age of Big Data,” is expansive; we could have long and fruitful discussions about practices, laws, and concerns in any of these domains. But a big part of the audience for this symposium is (...) students and faculty in higher education institutions (HEIs), and the subject of this paper is data analytics in our own backyards. Higher education learning analytics (LA) is something that most of us involved in this symposium are familiar with. Students have encountered LA in their courses, in their interactions with their law school or with their undergraduate institutions, instructors use systems that collect information about their students, and administrators use information to help understand and steer their institutions. More importantly, though, data analytics in higher education is something that those of us participating in the symposium can actually control. Students can put pressure on administrators, and faculty often participate in university governance. Moreover, the systems in place in HEIs are more easily comprehensible to many of us because we work with them on a day-to-day basis. Students use systems as part of their course work, in their residences, in their libraries, and elsewhere. Faculty deploy course management systems (CMS) such as Desire2Learn, Moodle, Blackboard, and Canvas to structure their courses, and administrators use information gleaned from analytics systems to make operational decisions. If we (the participants in the symposium) indeed care about Individual and Informational Privacy in the Age of Big Data, the topic of this paper is a pretty good place to hone our thinking and put into practice our ideas.

There is increasing concern about “surveillance capitalism,” whereby for-profit companies generate value from data, while individuals are unable to resist (Zuboff 2019). Non-profits using data-enabled surveillance receive less attention. Higher education institutions (HEIs) have embraced data analytics, but the wide latitude that private, profit-oriented enterprises have to collect data is inappropriate. HEIs have a fiduciary relationship to students, not a narrowly transactional one (see Jones et al, forthcoming). They are responsible for facets of student life beyond education. In addition (...) to classrooms, learning management systems, and libraries, HEIs manage dormitories, gyms, dining halls, health facilities, career advising, police departments, and student employment. HEIs collect and use student data in all of these domains, ostensibly to understand learner behaviors and contexts, improve learning outcomes, and increase institutional efficiency through “learning analytics” (LA). ID card swipes and Wi-Fi log-ins can track student location, class attendance, use of campus facilities, eating habits, and friend groups. Course management systems capture how students interact with readings, video lectures, and discussion boards. Application materials provide demographic information. These data are used to identify students needing support, predict enrollment demands, and target recruiting efforts. These are laudable aims. However, current LA practices may be inconsistent with HEIs’ fiduciary responsibilities. HEIs often justify LA as advancing student interests, but some projects advance primarily organizational welfare and institutional interests. Moreover, LA advances a narrow conception of student interests while discounting privacy and autonomy. Students are generally unaware of the information collected, do not provide meaningful consent, and express discomfort and resigned acceptance about HEI data practices, especially for non-academic data (see Jones et al. forthcoming). The breadth and depth of student information available, combined with their fiduciary responsibility, create a duty that HEIs exercise substantial restraint and rigorous evaluation in data collection and use.

Higher education institutions are mining and analyzing student data to effect educational, political, and managerial outcomes. Done under the banner of “learning analytics,” this work can—and often does—surface sensitive data and information about, inter alia, a student’s demographics, academic performance, offline and online movements, physical fitness, mental wellbeing, and social network. With these data, institutions and third parties are able to describe student life, predict future behaviors, and intervene to address academic or other barriers to student success (however defined). Learning (...) analytics, consequently, raise serious issues concerning student privacy, autonomy, and the appropriate flow of student data. We argue that issues around privacy lead to valid questions about the degree to which students should trust their institution to use learning analytics data and other artifacts (algorithms, predictive scores) with their interests in mind. We argue that higher education institutions are paradigms of information fiduciaries. As such, colleges and universities have a special responsibility to their students. In this article, we use the information fiduciary concept to analyze cases when learning analytics violate an institution’s responsibility to its students. (shrink)

I propose to consider the question, "Can machines think?" This should begin with definitions of the meaning of the terms "machine" and "think." The definitions might be framed so as to reflect so far as possible the normal use of the words, but this attitude is dangerous, If the meaning of the words "machine" and "think" are to be found by examining how they are commonly used it is difficult to escape the conclusion that the meaning and the answer to (...) the question, "Can machines think?" is to be sought in a statistical survey such as a Gallup poll. But this is absurd. Instead of attempting such a definition I shall replace the question by another, which is closely related to it and is expressed in relatively unambiguous words. The new form of the problem can be described in terms of a game which we call the 'imitation game." It is played with three people, a man (A), a woman (B), and an interrogator (C) who may be of either sex. The interrogator stays in a room apart front the other two. The object of the game for the interrogator is to determine which of the other two is the man and which is the woman. He knows them by labels X and Y, and at the end of the game he says either "X is A and Y is B" or "X is B and Y is A." The interrogator is allowed to put questions to A and B. We now ask the question, "What will happen when a machine takes the part of A in this game?" Will the interrogator decide wrongly as often when the game is played like this as he does when the game is played between a man and a woman? These questions replace our original, "Can machines think?". (shrink)

Psychologists and philosophers have recently been exploring whether the mechanisms which underlie the acquisition of ‘theory of mind’ (ToM) are best charac- terized as cognitive modules or as developing theories. In this paper, we attempt to clarify what a modular account of ToM entails, and why it is an attractive type of explanation. Intuitions and arguments in this debate often turn on the role of develop- ment: traditional research on ToM focuses on various developmental sequences, whereas cognitive modules are thought (...) to be static and ‘anti-developmental’. We suggest that this mistaken view relies on an overly limited notion of modularity, and we explore how ToM might be grounded in a cognitive module and yet still afford development. Modules must ‘come on-line’, and even fully developed modules may still develop internally, based on their constrained input. We make these points con- crete by focusing on a recent proposal to capture the development of ToM in a module via parameterization. (shrink)

Human social intelligence comprises a wide range of complex cognitive and affective processes that appear to be selectively impaired in autistic spectrum disorders. The study of these neuro- developmental disorders and the study of canonical social intelligence have advanced rapidly over the last twenty years by investigating the two together. Specifically, studies of autism have provided important insights into the nature of ‘theory of mind’ abilities, their normal development and underlying neural systems. At the same time, the idea of impaired (...) development of the neurocognitive mechanisms underlying ‘theory of mind’ has shed new light on the nature of autistic disorders. This general approach is not restricted to the study of impairments but extends to mapping areas of social intelligence that are spared in autism. Here we investigate basic moral judgment and find that it appears to be substantially intact in children with autism who are severely impaired in ‘theory of mind’. At the same time, we extend studies of moral reasoning in normal development by way of a new control task, the ‘cry baby’ task. Cry baby scenarios, in which the distress of the victim is ‘unreasonable’ or ‘unjustified,’ do not elicit moral condemnation from normally developing preschoolers or from children with autism. Judgments of moral transgressions in which the victim displays distress are therefore not likely the result of a simple automatic reaction to the distress and more likely involve moral reasoning. Mapping the cognitive co-morbidity patterns of disordered development should encompass both impairments and sparings because both will be needed to make sense of the neural and genetic levels.

The oeuvre of Brazilian-born and Parisian-educated Michael Löwy is widely recognised as the achievement of an exacting revolutionary cultural worker who integrates theory with his political duties, and labours hard at his craft so that the poetic imagination can reclaim and thereby re-enchant the reified reality of capitalist modernity. Nevertheless, when we come to Löwy’s reputation in the United States we face a curious situation. There is no doubt that his work is known and respected among many activists and scholars. (...) Yet from the perspective of the needs of the Marxist Left, the disparity is striking between what Löwy has to offer as a militant thinker and the actuality of his impact. The search for an explanation of such a discrepancy must begin with a preliminary stab at what I regard as a ‘Löwyian’ interpretation of Michael Löwy’s life and writings. The method includes an exploration of his possible ‘elective affinities’, defined in a broad sense, with the cultural and political work of US radicalism since the 1960s. Are there analogies, kinships, or attractions of meaning that have entered into a relationship of reciprocal appeal and influence? In the end, however, I conclude that the disproportion between potential and actual stems largely from fractional perceptions of his accomplishment that are rooted in the peculiarities of US Marxist thought in general and of US Trotskyism in particular. Such partial and one-sided assessments are a profound barrier because the achievement of Michael Löwy needs to be understood in its totality. (shrink)

Number concepts must support arithmetic inference. Using this principle, it can be argued that the integer concept of exactly ONE is a necessary part of the psychological foundations of number, as is the notion of the exact equality - that is, perfect substitutability. The inability to support reasoning involving exact equality is a shortcoming in current theories about the development of numerical reasoning. A simple innate basis for the natural number concepts can be proposed that embodies the arithmetic principle, supports (...) exact equality and also enables computational compatibility with real- or rational-valued mental magnitudes.

We use a new model of metarepresentational development to predict a cognitive deficit which could explain a crucial component of the social impairment in childhood autism. One of the manifestations of a basic metarepresentational capacity is a ‘ theory of mind ’. We have reason to believe that autistic children lack such a ‘ theory ’. If this were so, then they would be unable to impute beliefs to others and to predict their behaviour. This hypothesis was tested using Wimmer (...) and Perner’s puppet play paradigm. Normal children and those with Down’s syndrome were used as controls for a group of autistic children. Even though the mental age of the autistic children was higher than that of the controls, they alone failed to impute beliefs to others. Thus the dysfunction we have postulated and demonstrated is independent of mental retardation and specific to autism. (shrink)

While the image of the slave as the antithesis of the freeman is central to republican freedom, it is striking to note that slaves themselves have not contributed to how this condition is understood. The result is a one-sided conception of both freedom and slavery, which leaves republicanism unable to provide an equal and robust protection for historically outcast people. I draw on the work of Frederick Douglass – long overlooked as a significant contributor to republican theory – to show (...) one way why this is so. Focusing the American Revolution, the subsequent republican government established new political institutions to maintain the collective interests of the whole population. The political revolution was held in place by processes of public reason that reflected the values and ideas of the people that had rebelled. The black population, however, had not been part of this revolution. After emancipation, black Americans were required to accept terms of citizenship that had already been defined, leaving them socially dominated, subject to the prejudices and biases within the prevailing ideas of public discourse. Douglass argued that republican freedom under law is always dependent on a more fundamental revolution, that he calls a ‘radical revolution in thought’, in which the entire system of social norms and practices are reworked together by members of all constituent social groups – women and men, black and white, rich and poor – so that it reflects a genuinely collaborative achievement. Only then can we begin the republican project of contestatory freedom as independence or non-domination that today’s republicans take for granted. (shrink)

Black and Wilensky (1979) have made serious methodological errors in analyzing story grammars, and in the process they have committed additional errors in applying formal language theory. Our arguments involve clarifying certain aspects of knowledge representation crucial to a proper treatment of story understanding.Particular criticisms focus on the following shortcomings of their presentation: 1) an erroneous statement from formal language theory, 2) misapplication of formal language theory to story grammars, 3) unsubstantiated and doubtful analogies with English grammar, 4) various non (...) sequiturs concerning the generation of non‐stories, 5) a false claim based on the artificial distinction between syntax and semantics, and 6) misinterpretation of the role of story grammars in story understanding.We conclude by suggesting appropriate criteria for the evaluation of story grammars.

Although they were never to meet and corresponded only briefly, Catharine Macaulay and Mary Wollstonecraft shared a mutual admiration and a strong intellectual bond. Macaulay’s work had a profound and lasting effect on Wollstonecraft, and she developed and expanded on many of Macaulay’s ideas. While she often took these in a different direction, there remains a great synergy between their ideas to the extent that we can understand Wollstonecraft’s own feminist arguments by approaching them through the frameworks and ideas that (...) Macaulay provided. These included the principles of classical republicanism, particularly in its understanding of the values of freedom, equality and virtue, and an understanding of reason as grounded in immutable principles that apply equally to both sexes. On the question of women’s freedom and social equality with men, I argue that though Macaulay sets up the problem in far richer and more detailed philosophical terms, in the end it is Wollstonecraft that has the more compelling account of its far-reaching social implications and of how this might be addressed.

Even long after their formal exclusion has come to an end, members of previously oppressed social groups often continue to face disproportionate restrictions on their freedom, as the experience of many women over the last century has shown. Working within in a framework in which freedom is understood as independence from arbitrary power, Mary Wollstonecraft provides an explanation of why such domination may persist and offers a model through which it can be addressed. Republicans rely on processes of rational public (...) deliberation to highlight and combat oppression. However, where domination is primarily social rather than legal or political (such as where cultural attitudes, traditions and values exert an arbitrary and inhibiting force) then this defence against domination is often negated. Prejudice, she argues, ‘clouds’ people’s ability to reason and skews debate in favour of the dominant powers, thereby entrenching patterns of subjection. If they are to be independent, then, citizens require not only political rights but a platform from which to add their perspectives and interests to the background social values which govern political discussion.

In spite of its everyday connotations, the term independence as republicans understand it is not a celebration of individualism or self-reliance but embodies an acknowledgement of the importance of personal and social relationships in people’s lives. It reflects our connectedness rather than separateness and is in this regard a relational ideal. Properly understood, independence is a useful concept in addressing a fundamental problem in social philosophy that has preoccupied theorists of relational autonomy, namely how to reconcile the idea of individual (...) human agency with the inevitable and necessary influence of other people, both directly and indirectly. I derive my account from the work of Mary Wollstonecraft and Catharine Macaulay, whose contributions have remained largely overlooked by current republican theorists. I have three purposes in this chapter. First, I set out the relational character of independence. Secondly, I outline a republican approach to the problem of structural social threats to agency. Finally, I hope to establish the basis for a fruitful dialogue between republicans and relational autonomy theorists on the requirements and dynamics of individual agency and freedom in oppressive social situations. I identify three distinctive features of the internal logic of freedom as independence that give it a relational character: it always locates the person within a community; there is a mediating role played by the notion of arbitrariness in connecting individual and collective perspectives; a causal relationship exists linking each person’s freedom as independence such that that the dependence of one class of persons jeopardizes the independence of the whole community.

Republicans understand freedom as the guaranteed protection against any arbitrary use of coercive power. This freedom is exercised within a political community, and the concept of arbitrariness is defined with reference to the actual ideas of its citizens about what is in their shared interests. According to many current defenders of the republican model, this form of freedom is understood in strictly negative terms representing an absence of domination. I argue that this assumption is misguided. First, it is internally inconsistent. (...) The central republican focal point of arbitrariness is a necessarily socially constructed ideal that only exists as the creation of the citizens themselves. Second, republican freedom operates in two distinct realms or spheres. There is freedom under a law that is required to uphold the collective good as reflected in society’s norms, and there is freedom within that very system of norms. The threats to freedom from within each sphere are different and must be addressed accordingly. The negative approach, however, conflates the two and emphasises only the dangers faced under the law. This exposes citizens – especially those from marginalised social groups – to domination in the second realm from oppressive social norms. Only by clearly recognising the nature of both kinds of threats can a comprehensive republican freedom be formulated. (shrink)

Hegel and the Spirit explores the meaning of Hegel's grand philosophical category, the category of Geist, by way of what Alan Olson terms a pneumatological thesis. Hegel's philosophy of spirit, according to Olson, is a speculative pneumatology that completes what Adolf von Harnack once called the "orphan doctrine" in Christian theology--the doctrine of the Holy Spirit. Olson argues that Hegel's development of philosophy as pneumatology originates out of a deep appreciation of Luther's dialectical understanding of Spirit and that Hegel's (...) doctrine of Spirit is thus deeply interfused with the values of Würtemberg Pietism. Olson further maintains that Hegel's Enzyklopdie is the post-Enlightenment philosophical equivalent of a Trinitätslehre and that his Rechtsphilosophie is an ecclesiology. Thus Hegel and the Spirit demonstrates the truth of Karl Barth's observation that Hegel is the potential Aquinas of Protestantism. Exploring Hegel's philosophy of spirit in historical, cultural, and personal religious context, the book identifies Hegel's relationship with Hölderlin and his response to Hölderlin's madness as key elements in the philosopher's religious and philosophical development, especially with respect to the meaning of transcendence and dialectic.

It is well documented that people denied good human contact and interaction do not thrive well. One way people can be protected from the ravages of loneliness is animal companionship. Early laboratory observations of people with animals encouraged a period of research to identify, document, and assess the beneficial health implications of our relationship with companion animals. All indications are that companion animals play the role of a family member, often a member with the most desired attributes. Ordinary interactions with (...) animals can reduce blood pressure and alter survival after a heart attack. Pets, for some, afford increased opportunities to meet people, whereas for others, pets permit them to be alone without being lonely. The relationship between people and companion animals explains why people prefer alternatives to animal use for medical research. (shrink)
