We show, for each computable ordinal α and degree $\alpha > {0^{\left( \alpha \right)}}$, the existence of a torsion-free abelian group with proper α th jump degree α.

Grigorieff showed that forcing to add a subset of ω using partial functions with suitably chosen domains can add a generic real of minimal degree. We show that forcing with partial functions to add a subset of an uncountable κ without adding a real never adds a generic of minimal degree. This is in contrast to forcing using branching conditions, as shown by Brown and Groszek.

Contemporary discourses of management are full of encouragements to ‘expect the unexpected’ and to celebrate ‘the future of the future’. Many new public managerial technologies of change – such as steering labs, future games, and managerial performance arts – promise the co-creative ‘potentialization’ of employees, citizens and organizations. This paper approaches such potentialization technologies as immune mechanisms which serve to protect the social system from itself. From a perspective inspired by autopoietic systems theory, potentialization technologies provide autoimmunity by problematizing institutional (...) structures and providing ‘anti-structural’ space-times to facilitate transformation. There is a price to pay for this immune function, however, since these immune mechanisms cannot discriminate between productive and unproductive structures. By dissolving the certainty of the expectations that underlie the connectivity of diverse organizational operations, they risk harming the welfare systems that host them. (shrink)

Based upon an attentive reading of Nietzsche’s writings and his reception among post-Nietzschean thinkers, this book argues that Nietzsche’s philosophical enterprise constitutes a materialist metaphysics of pure becoming, of pure immanence and the power of the virtual.

During the late nineties, leading voices of the sex worker rights movement began to publicly question queer theory’s virtual silence on the subject of prostitution and sex work. However, this attempt by sex workers to “come out of the closet” into the larger queer theoretical community has thus far failed to bring much attention to sex work as an explicitly queer issue. Refusing the obvious conclusion—that queer theory’s silence on sex work somehow proves its insignificance to this field of inquiry—I (...) trace in Foucault’s oeuvre signs of an alternate (albeit differently) queer genealogy of prostitution and sex work. Both challenging and responding to long-standing debates about prostitution within feminist theory, I offer a new queer genealogy of sex work that aims to move beyond the rigid oppositions that continue to divide theorists of sexuality and gender. Focusing specifically on History of Madness (1961), Discipline and Punish (1975), and History of Sexuality Volume I (1976), I make the case for an alternate genealogy of sex work that takes seriously both the historical construction of prostitution and the lived experience of contemporary sex workers.

In opposition to any notion of poverty as privation, or ‘bare life’, Negrian discourse poses the problem of poverty as a precondition for innovation and self-constitution, that is, for the critical appropriation of the immeasurable. This appropriation, as depicted in Kairòs, Alma Venus, and Multitudo, occurs in the event of adequation, when the monstrous store of potentia (immanent to poverty) exposes itself to the void in the projection of the ‘to-come’. This essay seeks in turn to resolve a series of (...) vexing questions and problems concerning the function of poverty, love, and the monstrous in the Negrian constitution of reality. (shrink)

If it is true, as suggested by Sir Michael Marmot and other researchers, that status impacts health and therefore accounts for some of the social gradient in health, then it seems to be the case that it would be possible to bring about more equality in health by equalizing status. The purpose of this article is to analyze this suggestion. First, we suggest a working definition of what status precisely is. Second, following a luck egalitarian approach to distributive justice, we (...) consider whether and to which extent individuals are responsible themselves for their position in a status hierarchy. Third, we consider the contours of a difficult question, namely which political measures are feasible in order to reduce health-affective inequalities in status and fourth, whether or to what extent such measures are legitimate. We argue that on the basis of these considerations, we have at least some prima facie reasons to counter (at least some) status inequalities in order to equalize health. (shrink)

Open peer commentary on the article “Lived Experience and Cognitive Science Reappraising Enactivism’s Jonasian Turn” by Mario Villalobos & Dave Ward. Upshot: We argue that Villalobos and Ward’s criticism misses two crucial aspects of Varelian enactivism. These are, first, that enactivism attempts to offer a rigorous scientific justification for its teleological claims, and second, that enactivism in fact pays too little attention to the nature of human phenomenology and intentionality, rather than anthropomorphically over-valuing it.

A cornerstone of physics, Maxwell‘s theory of electromagnetism, apparently contains a fatal flaw. The standard expressions for the electromagnetic field energy and the self-mass of an electron of finite extension do not obey Einstein‘s famous equation, \, but instead fulfill this relation with a factor 4/3 on the left-hand side. Furthermore, the energy and momentum of the electromagnetic field associated with the charge fail to transform as a four-vector. Many famous physicists have contributed to the debate of this so-called 4/3-problem (...) without arriving at a complete solution. It has generally been assumed that, as originally suggested by Poincaré, the problems are connected to the question of stability of the charge distribution, and that relativistic equivalence between energy and self-mass can only be restored by inclusion of stabilizing forces. Alternative solutions to the problems have also been proposed. Nearly a century ago Fermi suggested a covariant definition of the electromagnetic energy and momentum, and sixty years later Kalckar et al. argued that the 4/3 problem is caused by omission of a relativistic correction in the standard evaluation of the self-force from Coulomb self-interaction. However, the relation between these suggestions has not been clear. We show that the relativistic correction implies that the mechanical momentum of an accelerated rigid body must be defined as the sum of the momenta of its parts for fixed time in the momentary rest frame of the body. For the total momentum of particles and field to be conserved, the total energy–momentum tensor must be divergence free, and this then requires that the momentum of the associated electromagnetic field be defined in the same way, consistent with the suggestion by Fermi. This comprehensive solution of the 4/3-problem demonstrates that there is no conflict of Maxwell‘s theory with special relativity and the questions of equivalence of electromagnetic energy and self-mass and of stability of a classical charge distribution are independent. In appendices we discuss the relations of our treatment with Fermi‘s seminal paper and with a classic paper by Dirac where he evaluated the damping self-force on a point electron from transport of energy and momentum in the electromagnetic field.

The primary question addressed in this article is how to understand and produce praxis development in the complex and contentious field of street communities of young marginalized men, an area highlighted almost on a daily basis in the Danish media under headlines with terms such as ‘foreigner problems’, ‘ghetto problems’, ‘gang conflicts’ and ‘gang war’. Since 2009, activists and professionals related to this field have gathered at Grundtvigs Højskole where they initiated and inspired community building activities in relation to the (...) recent gang conflicts in the Copenhagen area of Denmark. The article explores these practices and changes, including some of the communal initiatives arising in response to the escalating gang conflicts. The conflict and community building activities are contextualized in terms of broader tendencies and changes in Danish society, from enduring struggles with ethnic othering of young minority men since the late 1990s, to other societal changes escalating ‘gang-conflicts’ to ‘gang-war’. The article examines how these changes produce new dynamics, tensions and dimensions of binary thinking, which in turn creates new dilemmas in the everyday lives of the people involved in social work practice, community building activities and praxis research.

Context: Distributed language and interactivity are central members of a set of concepts that are rapidly developing into rigorous, exciting additions to 4E cognitive science. Because they share certain assumptions and methodological commitments with enactivism, the two have sometimes been confused; additionally, while enactivism is a well-developed paradigm, interactivity has relied more on methodological development and on a set of focal examples. Problem: The goal of this article is to clarify the core conceptual commitments of both interactivity-based and enactive approaches (...) to cognitive science by contrasting the two and highlighting their differences in assumptions, focus, and explanatory strategies. Method: We begin with the shared commitments of interactivity and enactivism - e.g., antirepresentationalism, naturalism, interdisciplinarity, the importance of biology, etc. We then give an overview of several important varieties of enactivism, including sensorimotor and anti-representationalist enactivism, and then walk through the history of the “core” varieties, taking care to contrast Maturana’s approach with that of Varela and the current researchers following in Varela’s footsteps. We then describe the differences between this latter group and interactivity-based approaches to cognitive science. Results: We argue that enactivism’s core concepts are explanatorily inadequate in two ways. First, they mis-portray the organization of many living systems, which are not operationally closed. Second, they fail to realize that most epistemic activity depends on engagement with non-local resources. Both problems can be dealt with by adopting an interactivity-based perspective, in which agency and cognition are fundamentally distributed and involve integration of non-local resources into the local coupling of organism and environment. Implications: The article’s primary goal is theoretical clarification and exposition; its primary implication is that enactive concepts need to be modified or extended in some way in order to explain fully many aspects of cognition and directed biological activity. Or, read another way, the article’s primary implication is that interactivity already provides a rich set of concepts for doing just that, which, while closely allied with enactivism in several ways, are not enactivist concepts. Constructivist content: The article consists entirely of a comparison between two constructivist fields of theory. Key Words: Interactivity, enactivism, distributed language, radical embodied cognitive science, ecological psychology, autonomy. (shrink)

Upshot: We agree with commenters that enactivism incorporates a broad variety of methodologies, metaphysical stances, concepts, and investigative approaches, and that this is a good thing. However, we remain concerned that autonomy and sense-making are problematic concepts for post-Varelian enactivism, and that they form the foundations of a conceptual framework that may hamper the development of effective explanations for cognitive activity, as well as the paradigmatic aspirations of this particular enactivist approach.

How can we distinguish one mind from another? How are we to determine what unifies the mind? Given radical mental disunity, these questions need to be answered.

In this exploratory paper, we investigate the extension of Haidt’s :814–834, 2001, The righteous mind: Why good people are divided by politics and religion, 2012) Moral foundations theory, operationalized as the MFQ30 questionnaire, from a sample of the general public across many countries to a sample of business students. MFT posits that people rely on five major concerns, or foundations, when making moral judgments. The five concerns are care/harm, fairness/cheating, loyalty/betrayal, respect/authority, and purity/degradation. In addition, Haidt suggests that intuition, rather (...) than reasoning, leads to moral judgment. We replicate Haidt’s measurement model and find that the measurement model based on our sample is consistent. This indicates support for MFT. Further, we find structural differences in the measurement model between the genders and between areas of study. Our findings suggest that all students in the sample focus substantially on the fairness foundation. Ethics education and research may seek to expand the number of moral foundations individuals consider when discerning whether something is right or wrong. (shrink)

Sociologist Niklas Luhmann argued that the law functions as society’s immune system by regulating conflicts that threaten the certainty of expectation structures. In this article, we argue that law itself has become a target of new social immune mechanisms. Since the 1980s, welfare states have increasingly seen their own structures as a threat. Today, the ideal is a public sector consisting of organizations that constantly emerge anew by selecting the structures that fit each specific moment, case, and citizen. To protect (...) public sector organizations against their own structures, ‘potentialization’ now functions as a social autoimmune mechanism by initiating a constant search for new openings and possibilities. This critique of structures includes a critique of legal structures like rights. Looking at the Danish law of early retirement as our empirical case, this paper analyzes, how the tension between law and ‘potentialization’ is built into the law itself. While the law gives citizens certain rights to early retirement, it simultaneously ‘protects’ against the same rights by potentializing citizens. ‘Potentialization’ here functions as a mechanism that protects the operations of a system against its legal structures. It functions by ‘un-relating’ those operations from the structures. This means that when citizens claim their right to pensions, the social workers can reject them on the grounds of a right to a future that is not foreclosed and ‘parked’ on a pension. The paper’s contribution is to show how potentialization works by dissolving even fundamental legal expectations. This profoundly transforms the relationship between the citizen and the public sector. (shrink)

This study adds to the empirical evidence supporting a significant connection between ethics and profitability by examining the connection between published reports of unethical behaviour by publicly traded U.S. and multinational firms and the performance of their stock. Using reports of unethical behaviour published in the Wall Street Journal from 1989 to 1993, the analysis shows that the actual stock performance for those companies was lower than the expected market adjusted returns. Unethical conduct by firms which is discovered and publicized (...) does impact on the shareholders by lowering the value of their stock for an appreciable period of time. Whatever their views on whether ethical behaviour is profitable, managers should be able to see a definite connection between unethical behaviour and the worth of their firm's stock. Stockholders, the press and regulators should find this information important in pressing for greater corporate and managerial accountability. (shrink)

We have previously built a small IKg ([Angle 89] and [Brooks 89]) six legged walking robot named Genghis. It was remarkably successful as a testbed to develop walking and learning algorithms. It encouraged us to build a more fully engineered robot with higher performance. We are building two copies of the robot, both 1.6Kg in mass. Their generic name is Attila. Attila has 24 actuators and over 150 sensors, all connected via a local network (the I2C bus) to 11 onboard (...) computers. (shrink)

We want to build tiny gnat-sized robots, a millimeter or two in diameter. They will be cheap, disposable, totally sefcontained autonomous agents able to do useful things in the world. This paper consists of two parts. The first describes why we want to build them. The second is a technical outline of how to go about it. Gnat robots are going to change the world.

An increasing vaccine hesitancy among parents, which has resulted in insufficient rates of immunization, provides reason to reconsider childhood vaccination practices. Studies suggest that parents' decision-making process concerning whether to vaccinate their child is highly influenced by cognitive biases. These biases can be utilized to increase vaccination uptake via changes in the choice context. This article considers childhood vaccination programmes, which involve children being vaccinated in school or daycare unless their parents actively ‘opt out’. We suggest that such programmes reconcile (...) parents' decisional authority and vaccination duties. First, opt-out childhood vaccination based in schools or daycare centres are not disrespectful of parental authority. Second, the programme aligns the default setting with a moral obligation to vaccinate one's child that most parents have. (shrink)

SWORD W, CLARK AM, HEGADOREN K, BROOKS S and KINGSTON D. Nursing Inquiry 2012; 19: 51–62 The complexity of postpartum mental health and illness: a critical realist studyPostpartum depression (PPD) is a major public health issue that profoundly impacts the woman, her infant and family. Although it may be linked to hormone changes, no direct hormonal aetiology has been established. A large body of evidence implicates numerous psychosocial predictors of PPD. While a history of depression predicts about 50% of cases (...) of PPD, it remains unclear why some women with a history do not develop depression following childbirth, even taking psychosocial factors into account. The aim of this study was to identify the main mechanisms and factors associated with the presence or absence of PPD in women with a history of depression, and the presence of PPD in women without a history, using a critical realist approach. The findings indicate a number of personal and contextual factors that influence postpartum mental health and illness. In addition, and perhaps most importantly, women who did not develop depression identified goal‐oriented actions that were protective. These factors and processes did not exist in isolation and the interplay among them in influencing health was apparent. More research is needed to explore the effects of these mechanisms in different contexts. (shrink)

Understanding what factors can positively or negatively affect farmers’ decisions to adopt new practices is of particular importance to agricultural researchers and practitioners. Few studies in adoption research have examined the role that fenceline neighbours can play in influencing the decisions of their neighbours to adopt new practices, especially in North America. Prior research on adoption suggests that there are spatial effects that exist in adoption decisions, such as the uptake of new farming practices. For example, previous qualitative research with (...) farmers has suggested that fenceline neighbours are influential but can have both positive and negative effects on adoption decisions. A standardized way of understanding fenceline neighbour influences is lacking. Our study presents a novel question set to examine fenceline neighbour dynamics and discusses its application in a survey examining the alternative practice adoption of adaptive multi-paddock grazing (AMP) by Canadian beef farmers. Our study highlights both the utility of our question set and how our question set can be used to provide new insights into local farmer social dynamics (e.g., how farmers engage with their neighbours and what factors influence engagement) and their influence on decisions to adopt. Specifically, our results identified two types of fenceline neighbour behaviors—engagers, and avoiders—and AMP farmers were more likely to be involved in engaged behaviors. Overall, we provide a question set that can be further integrated with trust, risk, and normative theoretical lenses to examine the role of fenceline neighbour dynamics in agricultural adoption and other contexts and call for more landholder research that examines neighbour-to-neighbour effects.
