Aristotle took practical wisdom to include cleverness, and something more. The hard question, that he does not explicitly answer, is what this something more is. On my interpretation, the practically wise are not merely more knowledgeable about what is good for people. They are also better able to discern all the values at stake, in whatever circumstances they find themselves. This is an ability that good people develop, typically rather late in life, provided they are masters of their own affairs. (...) According to Aristotle, this development is stunted by wickedness and also by wretchedness. It follows from his account that attempts to teach this virtue are not likely to succeed unless teachers have opportunities for developing practical wisdom through their work. Aristotle’s arguments give us reasons to doubt that teachers can help their students to become virtuous and wise, if their own way to earn a living is not conductive to human flourishing. If we take his message to heart, we should, first and foremost, think about how to steer clear of wretched work conditions, where teachers’ moral agency is narrowly circumscribed. (shrink)

The Emergic Cognitive Model (ECM) is a unified computational model of visual filling-in based on the Emergic Network architecture. The Emergic Network was designed to help realize systems undergoing continuous change. In this thesis, eight different filling-in phenomena are demonstrated under a regime of continuous eye movement (and under static eye conditions as well). -/- ECM indirectly demonstrates the power of unification inherent with Emergic Networks when cognition is decomposed according to finer-grained functions supporting change. These can interact to raise (...) additional emergent behaviours via cognitive re-use, hence the Emergic prefix throughout. Nevertheless, the model is robust and parameter free. Differential re-use occurs in the nature of model interaction with a particular testing paradigm. -/- ECM has a novel decomposition due to the requirements of handling motion and of supporting unified modelling via finer functional grains. The breadth of phenomenal behaviour covered is largely to lend credence to our novel decomposition. -/- The Emergic Network architecture is a hybrid between classical connectionism and classical computationalism that facilitates the construction of unified cognitive models. It helps cutting up of functionalism into finer-grains distributed over space (by harnessing massive recurrence) and over time (by harnessing continuous change), yet simplifies by using standard computer code to focus on the interaction of information flows. Thus while the structure of the network looks neurocentric, the dynamics are best understood in flowcentric terms. Surprisingly, dynamic system analysis (as usually understood) is not involved. An Emergic Network is engineered much like straightforward software or hardware systems that deal with continuously varying inputs. Ultimately, this thesis addresses the problem of reduction and induction over complex systems, and the Emergic Network architecture is merely a tool to assist in this epistemic endeavour. -/- ECM is strictly a sensory model and apart from perception, yet it is informed by phenomenology. It addresses the attribution problem of how much of a phenomenon is best explained at a sensory level of analysis, rather than at a perceptual one. As the causal information flows are stable under eye movement, we hypothesize that they are the locus of consciousness, howsoever it is ultimately realized. (shrink)

In Chapter VIII of Democracy and Education, Dewey objects to all three of the following propositions: (1) education serves predefined aims; (2) Education serves aims that are external to the process of education; and (3) Education serves aims that are imposed by authority. From the vantage point of policy-makers and authors of curriculum guides, these three propositions seem plausible, even self-evident. In this paper, I set forth a critical interpretation and evaluation of Dewey’s objections to them and argue that he (...) saw the aims of education from another point of view, that of a learner. From a learner’s point of view, propositions 2 and 3 are only half-true because external aims that are not shared by the students cannot successfully guide educative activities. As regards proposition 1, Dewey’s philosophy does not accommodate the birds-eye view required to make it literally true. As learners, we cannot have an external view of our entire progress. Some of our aims are, therefore, not predefined but discovered on the way. Dewey’s stance on the role of aims in education is worth serious consideration, because the view of curriculum development and school administration that these three propositions engender is as deeply problematic today as it was when Dewey wrote against them a century ago.

The dominant model of curriculum design in the last century assumed that school education could be organized around aims, defined primarily in terms of students' behaviour. The credentials of this model were questioned by, among others, Lawrence Stenhouse, who pointed out that education serves purposes that cannot be stated in terms of behavioural objectives. In this article, I offer support for Stenhouse's conclusion and go beyond it, showing that if education aims at critical understanding of its own value, then it (...) is even more radically open-ended than Stenhouse argued.My argument is based on two premises. One of them is that the reason why people disagree about what education involves is that they have less-than-perfect knowledge of what human characteristics are worth cultivating. This premise is supported by a theory of meaning advanced by Hilary Putnam. The other premise is that one of the aims of education is intellectual independence. From these premises, I conclude that a successful course of education serves purposes that cannot be completely stated in advance. (shrink)

A technocratic model of curriculum design that has been highly influential since the middle of last century assumes that the aims of education can be, and should be: 1. Causally brought about by administering educational experiences; 2. Specified as objectives that can be attained, reached or completed; 3. Changes in students that are described in advance. Richard S. Peters argued against the first of these three tenets by making a distinction between aims that are causally brought about by the means (...) and aims that are constituted by the means. I argue that further distinctions between ways in which ends and means can be related throw doubt on the remaining two tenets. My argument against the second one rests on a distinction between open aims that cannot be completed and closed aims that can be reached. I use a third distinction, between aims as principles of design and aims as principles of reform, to show that the third tenet of the technocratic model is also suspect. I conclude that a realistic view of educational aims must take into account that they are more multifarious than envisaged by the technocratic model of curriculum design. (shrink)

In a paper published in 1930, John Dewey said that for many years Democracy and Education was the book where his philosophy “was most fully expounded”.1,2 If we add to this the fact that Dewey was known as the philosopher of democracy, then we have reason to expect the text to say something important, not only about education, but also about democracy. Nevertheless, all twenty-six chapters of the book are about schools and education and, when it was originally published in (...) 1916, it had the subtitle An Introduction to the Philosophy of Education.

Self-regulatory processes have predominantly been linked to the study of academic achievement in terms of learning behavior, cognitive engagement, and specific academic performance measures. If poorly regulated, academic behavior can have repercussions on social adaptation. Motivational processes constitute the other key element in ensuring successful regulation, as studies indicate that self-regulation can effectively influence achievement outcomes if learners have positive beliefs about their personal ability to negotiate difficulties and work towards the desired learning outcomes. This book takes a critical look (...) at the role of self-regulatory processes and personal agency beliefs in academic and social self-regulatory functioning, providing the reader with theoretical understanding of the issues and lending empirical support to the relevance of these processes in the East Asian educational context. In this way, the study explores the extent to which self-regulation and personal agency beliefs can offer an alternative explanation for the academic performance of students. (shrink)

Charles Darwin hoped that a large body of working naturalists would embrace evolution after the Origin of Species appeared in late 1859. He was disappointed. His evolutionary ideas at first made painfully little progress in the scientific community. But by 1863 the tide had turned dramatically, and within five years evolution became scientific orthodoxy in Britain. The Origin's reception followed this peculiar trajectory because Darwin had not initially tied its theory to productive original scientific investigation, which left him vulnerable to (...) charges of reckless speculation. The debate changed with his successful application of evolution to original problems, most notably orchid fertilization, the subject of a well‐received book in 1862. Most of Darwin's colleagues found the argument of the Origin convincing when they realized that it functioned productively in the day‐to‐day work of science—and not before. The conceptual force of the Origin, however outwardly persuasive, acquired full scientific legitimacy only when placed “in the harness of daily labour.”. (shrink)

The Samenleving and Bedrijf (S&B) network of Dutch organizations seeks to embed corporate social responsibility (CSR) within business practices but faces challenges with regard to how to do so across various organizational practices, processes, and policies. The integration of CSR demands cultural change driven by senior management and other change agents, who push CSR principles throughout the organization. This study examines the change processes that S&B member organizations have initiated, with a particular focus on the role of high potentials—those persons (...) who have been selected for the fast track into senior management. Interviews with nine S&B organizations document their levels of CSR integration and implementation, the role of senior managers, and the effects of high potentials’ competencies on the realignment process. High potentials have the ability and opportunity to act as CSR change agents, but organizations’ expectations of their purposes as future senior managers prevented them from doing so. In the existing organizational cultures, leadership focused on economic success, and the CSR implementation process had just initiated. Therefore, a measure of CSR embeddedness might refer to the performance measurement and expectations of high potentials as potential CSR change agents. (shrink)

This paper has two aims. One is to draw a distinction between two types of trust. The other is to argue for its applicability in academic discourse on educational policies. One of the two types of trust is ethical trust that rests on beliefs about others’ ethical virtues. The other is institutional trust that typically depends on law enforcement and economic incentives. Ideas about a social order based primarily on institutional trust have haunted political thought since the time of Thomas (...) Hobbes. Such ideas may seem realistic if we focus on business relations, where conformity to contractual terms suffices to meet the needs of all concerned. Intimate relationships rely more on ethical trust. In the first half of the paper the difference between these two types of trust is explained. In the final sections it is argued that successful schoolwork depends on ethical trust and that measures to make schools more reliable in the institutional sense, through supervision and accountability, need to be applied with caution. Such measures can undermine ethical trust because they, at least implicitly, question the moral integrity of teachers and school-heads. (shrink)

As the functional capabilities of high-tech medical products converge, supplying organizations seek new opportunities to differentiate their offerings. Embracing product sustainability-related differentiators provides just such an opportunity. This study examines the challenge organizations face when attempting to understand how customers perceive environmental and social dimensions of sustainability by exploring and defining both dimensions on the basis of a review of extant literature and focus group research with a leading supplier of magnetic resonance imaging (MRI) scanning equipment. The study encompasses seven (...) hospitals and one private imaging center in the Netherlands and identifies five social aspects that cover 11 indicators. The authors conduct 22 customer perception interviews with key decision-making stakeholders involved in purchasing MRI scanning equipment. Respondents find environmental and social sustainability dimensions personally relevant but professionally secondary to cost, performance, and ability to use the equipment in their organizations' physical infrastructure. Finally, incorporating a product's environmental and social credentials within the marketing of MRI scanning equipment enhances the perception of the product offering in decisionmaking stakeholders' minds and provides a means of differentiation.

Abstract:One of the themes that runs through Dewey’s Experience and Education is an argument to the effect that education aims at self-control. The details of this argument reveal close affinity between Dewey’s philosophy of education and the ideals of the Enlightenment. They are also strikingly similar to John Locke’s thoughts about freedom and education published in the seventeenth century. Comparison of their texts shows that Dewey and Locke worked with similar distinctions between positive and negative freedom. They both saw freedom (...) and guidance as compatible, and conceived of self-control as dependent on autonomy-friendly habits instilled through education. (shrink)

Connectionism is currently one of the most flourishing and interdisciplinary areas of cognitive science. Drawing on research in neural computation and networks it has found applications in areas such as psychology and animal intelligence. By using types of network which attempt to mirror our own cognitive architecture, connectionism is making breakthroughs in the understanding of the human mind a real possibility.

The aim of this paper is to demonstrate a prima facie tension between our commonsense conception of ourselves as thinkers and the connectionist programme for modelling cognitive processes. The language of thought hypothesis plays a pivotal role. The connectionist paradigm is opposed to the language of thought; and there is an argument for the language of thought that draws on features of the commonsense scheme of thoughts, concepts, and inference. Most of the paper (Sections 3-7) is taken up with the (...) argument for the language of thought hypothesis. The argument for an opposition between connectionism and the language of thought comes towards the end (Section 8), along with some discussion of the potential eliminativist consequences (Sections 9 and..

Connectionist models provide a promising alternative to the traditional computational approach that has for several decades dominated cognitive science and artificial intelligence, although the nature of connectionist models and their relation to symbol processing remains controversial. Connectionist models can be characterized by three general computational features: distinct layers of interconnected units, recursive rules for updating the strengths of the connections during learning, and “simple” homogeneous computing elements. Using just these three features one can construct surprisingly elegant and powerful models of (...) memory, perception, motor control, categorization, and reasoning. What makes the connectionist approach unique is not its variety of representational possibilities or its departure from explicit rule-based models, or even its preoccupation with the brain metaphor. Rather, it is that connectionist models can be used to explore systematically the complex interaction between learning and representation, as we try to demonstrate through the analysis of several large networks.

There is disagreement over the notion of representation in cognitive science. Many investigators equate representations with symbols, that is, with syntactically defined elements in an internal symbol system. In recent years there have been two challenges to this orthodoxy. First, a number of philosophers, including many outside the symbolist orthodoxy, have argued that "representation" should be understood in its classical sense, as denoting a "stands for" relation between representation and represented. Second, there has been a growing challenge to orthodoxy under (...) the banner of connectionism. Although this connectionist challenge has evoked emotionally-charged rebukes from the symbolist camp, connectionists as a group have not articulated a conception of representation to replace the symbolist view. Nonetheless, most agree on the need for a nonsymbolic notion of representation. This paper advances a "stands for" sense of representation as primary by incorporating it into a general approach to cognitive science consonant with the connectionism. The idea is to marry connectionism to a particular version of functionalism, viz., one that builds its notion of "function" on the similarity between functional analysis in biology and in psychology. It builds on my earlier work adapting and revising Marr's tri-level approach to cognition. My proposal frees Marr's analysis from its moorings in the orthodox symbolic view of representation and allies it with a notion of functional analysis akin to that proposed by Cummins, developed further by Haugeland, and invoked by Millikan and Dretske. Unlike these authors, however, I do not wed representation to a general belief-desire analysis of behavior. Rather, I follow what I take to be the lesson of psychological practice, according to which the investigator does not seek to explain behavior in general but seeks to analyze the cognitive capacities that underlie behavior, such as vision, memory, learning, and linguistic capacities. Accordingly, ascriptions of representational content are made not by working back from belief-desire ascriptions, but in the context of forming psychological models to account for specific cognitive capacities. Because conceptions of representation in cognitive science typically are embedded in a general approach to the study of cognition, arguments for the comparative plausibility of a particular conception of representation must scout these larger frameworks. I therefore begin by characterizing the interlocking set of assumptions that gave life to the orthodox symbolist approach, paying special attention to the complementarity between representation and process that naturally arises from those assumptions. I then consider two versions of an alternative approach to representation: Dretske's and my own. Finally, I urge the merits of the "cognitive capacities" over the "belief-desire" approach to the subject-matter of cognitive science. (shrink)

Over the last decade, fully distributed models have become dominant in connectionist psychological modelling, whereas the virtues of localist models have been underestimated. This target article illustrates some of the benefits of localist modelling. Localist models are characterized by the presence of localist representations rather than the absence of distributed representations. A generalized localist model is proposed that exhibits many of the properties of fully distributed models. It can be applied to a number of problems that are difficult for fully (...) distributed models, and its applicability can be extended through comparisons with a number of classic mathematical models of behaviour. There are reasons why localist models have been underused, though these often misconstrue the localist position. In particular, many conclusions about connectionist representation, based on neuroscientific observation, can be called into question. There are still some problems inherent in the application of fully distributed systems and some inadequacies in proposed solutions to these problems. In the domain of psychological modelling, localist modelling is to be preferred. Key Words: choice; competition; connectionist modelling; consolidation; distributed; localist; neural networks; reaction-time. (shrink)

This paper reviews four significant advances on the feedforward architecture that has dominated discussions of connectionism. The first involves introducing modularity into networks by employing procedures whereby different networks learn to perform different components of a task, and a Gating Network determines which network is best equiped to respond to a given input. The second consists in the use of recurrent inputs whereby information from a previous cycle of processing is made available on later cycles. The third development involves (...) developing compressed representations of strings in which there is no longer an explicit encoding of the components but where information about the structure of the original string can be recovered and so is present functionally. The final advance entails using connectionist learning procedures not just to change weights in networks but to change the patterns used as inputs to the network. These advances significantly increase the usefulness of connectionist networks for modeling human cognitive performance by, among other things, providing tools for explaining the productivity and systematicity of some mental activities, and developing representations that are sensitive to the content they are to represent.

The emphasis in the connectionist sentence‐processing literature on distributed representation and emergence of grammar from such systems can easily obscure the often close relations between connectionist and symbolist systems. This paper argues that the Simple Recurrent Network (SRN) models proposed by Jordan (1989) and Elman (1990) are more directly related to stochastic Part‐of‐Speech (POS) Taggers than to parsers or grammars as such, while auto‐associative memory models of the kind pioneered by Longuet–Higgins, Willshaw, Pollack and others may be useful for grammar (...) induction from a network‐based conceptual structure as well as for structure‐building. These observations suggest some interesting new directions for specifically connectionist sentence processing research, including more efficient representations for finite state machines, and acquisition devices based on a distinctively connectionist basis for grounded symbolist conceptual structure.

ObjectiveTo demonstrate that the human brain, as a connectionist system, has the capacity to become a free, rational, moral, agent—that is, the capacity to become a self—and that the brain becomes a self by engaging second-order reflection in the hermeneutical task of constructing narratives that rationalise action. StructureSection 2 explains the connectionist brain and its relevant capacities: to categorise, to develop goal-directed dispositions, to problem-solve what it should do, and to second-order reflect. Section 3 argues that the connectionist brain constitutes (...) a self by constructing rational narratives. Section 4 replies to the objection that the connectionist self cannot be free. Conclusion Treating the brain as a connectionist system provides a way to explain the free rational agency of the “connectionist” self. (shrink)

Recently, connectionist models have been developed that seem to exhibit structuresensitive cognitive capacities without executing a program. This paper examines one such model and argues that it does execute a program. The argument proceeds by showing that what is essential to running a program is preserving the functional structure of the program. It has generally been assumed that this can only be done by systems possessing a certain temporalcausal organization. However, counterfactualpreserving functional architecture can be instantiated in other ways, for (...) example geometrically, which are realizable by connectionist networks. (shrink)

Naturally occurring speech contains only a limited amount of complex recursive structure, and this is reflected in the empirically documented difficulties that people experience when processing such structures. We present a connectionist model of human performance in processing recursive language structures. The model is trained on simple artificial languages. We find that the qualitative performance profile of the model matches human behavior, both on the relative difficulty of center‐embedding and cross‐dependency, and between the processing of these complex recursive structures and (...) right‐branching recursive constructions. We analyze how these differences in performance are reflected in the internal representations of the model by performing discriminant analyses on these representations both before and after training. Furthermore, we show how a network trained to process recursive structures can also generate such structures in a probabilistic fashion. This work suggests a novel explanation of people's limited recursive performance, without assuming the existence of a mentally represented competence grammar allowing unbounded recursion. (shrink)

Despite the burgeoning literature on the governance and impact of cross-sector partnerships in the past two decades, the debate on how and when these collaborative arrangements address globally relevant problems and contribute to systemic change remains open. Building upon the notion of wicked problems and the literature on governing such wicked problems, this paper defines harnessing problems in multi-stakeholder partnerships as the approach of taking into account the nature of the problem and of organizing governance processes accordingly. The paper develops (...) an innovative analytical framework that conceptualizes MSPs in terms of three governance processes harnessing three key dimensions of wicked problems. The Roundtable on Sustainable Palm Oil provides an illustrative case study on how this analytical framework describes and explains organizational change in partnerships from a problem-based perspective. The framework can be used to better understand and predict the complex relationships between MSP governance processes, systemic change and societal problems, but also as a guiding tool in organizing governance processes to continuously re-assess the problems over time and address them accordingly.

Abstract Physiological psychology has its conceptual roots in stimulus?response behaviourism. The resurgence of cognitive concepts in mainstream psychology has led to a separation between the two, largely due to the failure of most cognitive theories to specify how their explanatory processes could be realised in the nervous system.

The problem is that connectionism takes a radically different view of the brain from that adopted in traditional physiological (...) psychology. This paper looks at some of the implications of connectionism for how physiological psychology should develop.

Socioeconomic status -related health disparities persist for numerous chronic diseases, with lower-SES individuals exhibiting greater risk of morbidity and mortality compared to their higher-SES counterparts. One likely contributor is disparities in health messaging efforts, which are currently less effective for motivating health behavior change among those lower in SES. Drawing on communication neuroscience and social neuroscience research, we describe a conceptual framework to improve health messaging effectiveness in lower SES communities. The framework is based on evidence that health-message-induced activity in (...) the ventral striatum and subdivisions of the medial pre-frontal cortex predicts behavior change. Additionally, we draw from social neuroscience work showing that activity in these regions during valuation and the processing of self-related vs. social information, differs as a function of SES. Bringing together these previously disparate lines of work, we argue that health messages emphasizing the benefits to close others of engaging in behavior change will be more effective among lower SES individuals. We also outline a research agenda based on our framework. Ultimately, we hope that this framework utilizing a “brain-as-predictor” approach generates novel insights about the neural underpinnings of message-induced behavior change among lower SES individuals, and helps to close the gap in SES-based health disparities by harnessing the power of neuroimaging.

In Connectionism and the Philosophy of Psychology, Horgan and Tienson articulate and defend a new view of cognition.

Connectionism provides hope for unifying work in neuroscience, computer science, and cognitive psychology. This promise has met with some resistance from Classical Computionalists, which may have inspired Connectionists to retaliate with bold, inflationary claims on behalf of Connectionist models. This paper demonstrates, by examining three intimately connected issues, that these inflationary claims made on behalf of Connectionism are wrong. This should not be construed as an attack on Connectionism, however, since the inflated claims made on its behalf (...) have the look of cures for which there are no ailments. There is nothing wrong with Connectionism for its failure to solve illusory problems. (shrink)

The relation between logic and thought has long been controversial, but has recently influenced theorizing about the nature of mental processes in cognitive science. One prominent tradition argues that to explain the systematicity of thought we must posit syntactically structured representations inside the cognitive system which can be operated upon by structure sensitive rules similar to those employed in systems of natural deduction. I have argued elsewhere that the systematicity of human thought might better be explained as resulting from the (...) fact that we have learned natural languages which are themselves syntactically structured. According to this view, symbols of natural language are external to the cognitive processing system and what the cognitive system must learn to do is produce and comprehend such symbols. In this paper I pursue that idea by arguing that ability in natural deduction itself may rely on pattern recognition abilities that enable us to operate on external symbols rather than encodings of rules that might be applied to internal representations. To support this suggestion, I present a series of experiments with connectionist networks that have been trained to construct simple natural deductions in sentential logic. These networks not only succeed in reconstructing the derivations on which they have been trained, but in constructing new derivations that are only similar to the ones on which they have been trained.

Objective: Collaborative governance is an innovative approach to address complex societal challenges, involving partnerships between state and non-state actors. Consequently, social media is powerful tools for promoting transparency and accountability. Methodology: The study examines the role of non-state actors in leveraging social media to enhance transparency in collaborative governance initiatives. The research analyses two case studies - the #FeesMustFall campaign in South Africa and the #Tajamuka/Sesijikile campaign in Zimbabwe. Results: Through a qualitative analysis of the case studies, the study explores (...) how non-state actors, such as civil society organizations and activist groups, have utilized social media to amplify their voices, mobilize public support, and exert pressure on government entities. Findings reveal that effective use of social media can empower non-state actors to overcome information asymmetries, facilitate public scrutiny, and foster collaborative problem-solving. Conclusions: However, contextual factors, such as political environments and digital access, shapes the dynamics of social media-driven transparency efforts. (shrink)

In this paper we defend a position we call radical connectionism. Radical connectionism claims that cognition _never_ implicates an internal symbolic medium, not even when natural language plays a part in our thought processes. On the face of it, such a position renders the human capacity for abstract thought quite mysterious. However, we argue that connectionism is committed to an analog conception of neural computation, and that representation of the abstract is no more problematic for a system (...) of analog vehicles than for a symbol system. Natural language is therefore not required as a representational medium for abstract thought. Since natural language is arguably not a representational medium _at all_, but a conventionally governed scheme of communicative signals, we suggest that the role of internalised (i.e., self- directed) language is best conceived in terms of the coordination and control of cognitive activities within the brain.

The cyclic GMP‐AMP synthase–stimulator of interferon genes (cGAS‐STING) pathway is central for the initiation of anti‐tumoural immune responses. Enormous effort has been made to optimise the design and administration of STING agonists to stimulate tumour immunogenicity. However, in certain contexts the cGAS‐STING axis fuels tumourigenesis. Here, we review recent findings on the regulation of cGAS expression and activity. We particularly focus our attention on the DNA‐dependent protein kinase (DNA‐PK) complex, that recently emerged as an activator of inflammatory responses in tumour (...) cells. We propose that stratification analyses on cGAS and DNA‐PK expression/activation status should be carried out to predict treatment efficacy. We herein also provide insights into non‐canonical functions borne by cGAS and cGAMP, highlighting how they may influence tumourigenesis. All these parameters should be taken into consideration concertedly to choose strategies aiming to effectively boost tumour immunogenicity. (shrink)
