The organizational theory literature is reasonably unanimous that team autonomy is a key factor for employee well-being and motivation as well as organizational performance. However, team autonomy is challenged when its processes and outputs need to be aligned with actors and factors external to a team. There are likely challenges and conflicts between team autonomy and the need for coherence in the wider system. Team autonomy has a range of implications and is challenged by a number of factors, such as (...) knowledge complexity and decision-making, learning, large-scale problems, product and technical interdependencies, the use of platforms, virtual collaboration and diversity. Alignment with the external is particularly necessary in multi-team environments with many technical interdependencies, where a single team’s failure to deliver a sufficient level of quality may lead to system-wide consequences. Therefore, teams in complex environments increasingly need to regulate and manage their work in cooperation with internal and external partners and systems. Such dependencies challenge team autonomy. In this special issue of AI&S, we want to address these topics in more detail, particularly in the context of software-intensive organizations and digital transformations. The scope and, thus, the consequences of a team’s work can be far-reaching when the team’s effort and output take place partially or completely in fully digitized contexts and processes. The articles in this special issue show various ways of dealing with the challenge of balancing autonomy and alignment with the external. A key focus is to show the buffering function: how teams, with the help of processes, technology, new organizational forms and time and space are able to find the buffer needed for maintaining team autonomy.

This paper proposes a roadmap for how privacy leakages from outsourced managed security services using intrusion detection systems can be controlled. The paper first analyses the risk of leaking private or confidential information from signature-based intrusion detection systems. It then discusses how the situation can be improved by developing adequate privacy enforcement methods and privacy leakage metrics in order to control and reduce the leakage of private and confidential information over time. Such metrics should allow for quantifying how much information (...) that is leaking, where these information leakages are, as well as showing what these leakages mean. This includes adding enforcement mechanisms ensuring that operation on sensitive information is transparent and auditable. The data controller or external quality assurance organisations can then verify or certify that the security operation operates in a privacy friendly manner. The roadmap furthermore outlines how privacy-enhanced intrusion detection systems should be implemented by initially providing privacy-enhanced alarm handling and then gradually extending support for privacy enhancing operation to other areas like digital forensics, exchange of threat information and big data analytics based attack detection.

In our lives, we aim to achieve welfare for ourselves, that is, to live good lives. But we also have another, more impartial perspective, where we aim to balance our concern for our own welfare against a concern for the welfare of others. This is a perspective of justice. Nils Holtug examines these two perspectives and the relations between them.

Online news sites have become an internet ‘staple’, but we know little of the forces driving the popularity of such sites in relation to what could be understood as the latest iteration of the web – social media services. This research in brief article discusses empirical results regarding the uses of Twitter for news sharing. Specifically, we present a comparative analysis of links emanating from the service at hand to a series of media outlets over a six-month period in two (...) countries; Sweden and Norway. Focusing on linking practices among highly active Twitter accounts, we problematize the assumption that online communication involves two or more humans by directing attention to more or less automated ‘bot’ accounts. In sum, it is suggested that such automated accounts need to be dealt with more explicitly by researchers as well as practitioners interested in the popularity of online news as expressed through social media activity.

In bilateral logic formulas are signed by + and –, indicating the speech acts assertion and denial. I argue that making an assumption is also speech act. Speech acts cannot be embedded within other speech acts. Hence we cannot make sense of the notion of making an assumption in bilateral logic. Attempts to solve this problem are considered and rejected.

ABSTRACTEvaluative aesthetic discourse communicates that the speaker has had first-hand experience of what is talked about. If you call a book bewitching, it will be assumed that you have read the book. If you say that a building is beautiful, it will be assumed that you have had some visual experience with it. According to an influential view, this is because knowledge is a norm for assertion, and aesthetic knowledge requires first-hand experience. This paper criticizes this view and argues for (...) an alternative view, according to which aesthetic discourse expresses affective states of mind, analogously to how assertions express beliefs. It is because these affective states require first-hand experience that aesthetic discourse communicates that such acquaintance is at hand. The paper furthermore argues that the lack of an experience requirement for aesthetic belief ascriptions constitutes a problem for the kind of expressivist who claims that evaluative belief states are covert non-cognitive states.

It is widely held within contemporary metaethics that there is a lack of linguistic support for evaluative expressivism. On the contrary, it seems that the predictions that expressivists make about evaluative discourse are not borne out. An instance of this is the so-called problem of missing Moorean infelicity. Expressivists maintain that evaluative statements express non-cognitive states of mind in a similar manner to how ordinary descriptive language expresses beliefs. Conjoining an ordinary assertion that p with the denial of being in (...) the corresponding belief state famously gives rise to Moorean infelicity:?? It’s raining but I don’t believe that it’s raining. If expressivists are right, then conjoining evaluative statements with the denial of being in the relevant non-cognitive state of mind should give rise to similar infelicity. However, as several theorists have pointed out, this does not seem to be the case. Statements like the following are not infelicitous: Murder is wrong but I don’t disapprove of it. In this paper, I argue that evaluative statements express the kind of states that are attributed by ‘find’-constructions in English and that these states are non-cognitive in nature. This addresses the problem of missing Moorean infelicity and, more generally, goes to show that there are linguistic facts which support expressivism about evaluative discourse. (shrink)

Ethicism is the most comprehensively defended answer to the question regarding whether ethical properties determine aesthetic properties in artworks. According to ethicism, aesthetically relevant ethical flaws in artworks count as aesthetic flaws and aesthetically relevant ethical merits count as aesthetic merits. In this paper, I argue that ethicism’s most significant argument, the Merited Response Argument suffers from an ambiguity that makes it either unsound or uninteresting. Specifically, the notion of an artwork’s ‘prescribing’ a response, central to MRA, is ambiguous between (...) merely attempting to elicit a response from appreciators as appropriate to a work, and endorsing a response as appropriate to relevant parts of the actual world. While the first sense of ‘prescribe’ does the aesthetic work, the second does the ethical. (shrink)

According to the Harm Principle, roughly, the state may coerce a person only if it can thereby prevent harm to others. Clearly, this principle depends crucially on what we understand by harm. Thus, if any sort of negative effect on a person may count as a harm, the Harm Principle will fail to sufficiently protect individual liberty. Therefore, a more subtle concept of harm is needed. I consider various possible conceptions and argue that none gives rise to a plausible version (...) of the Harm Principle. Whether we focus on welfare, quantities of welfare or qualities of welfare, we do not arrive at a plausible version of this principle. Instead, the concept of harm may be moralized. I consider various ways this may be done as well as possible rationales for the resulting versions of the Harm Principle. Again, no plausible version of the principle turns up. I also consider the prospect of including the Harm Principle in a decision-procedure rather than in a criterion of rightness. Finally, in light of my negative appraisal, I briefly discuss why this principle has seemed so appealing to liberals. (shrink)

The right to health is enshrined in the constitution of the World Health Organization and numerous other international agreements. Yet today, an estimated 5.7 million people die each year from treatable infectious diseases, most of which are susceptible to existing antimicrobials if they were accessible. These deaths occur predominantly among populations living in poverty in low- and middle-income countries, and they greatly exceed the estimated 700,000 annual deaths worldwide currently attributed to antimicrobial resistance. Ensuring universal appropriate access to antimicrobials is (...) not only a critical part of realizing the right to health, it is necessary for mobilizing effective collective action against the development and spread of AMR.

In this paper I take up John Searle's account of ?Background capacities? to render intelligible the presupposed and hidden aspects of the background conditions that enable the performance of skilled movement. The paper begins with a review of Searle's initial account of Background capacities and how this picture can be applied to account for skilled movement in sport. Then an objection to this picture is addressed, claiming that Searle's initial picture might ?overrepresentationalise? background conditions. Moreover, this objection prompts how Searle (...) has modified his initial picture of background conditions in accordance with his more recent ?connection principle?. Searle's recent account of background conditions is then elaborated and discussed in the second half of the paper. The discussion emphasises three distinct levels of analysis in Searle's framework necessary to a full understanding of his background conditions: (i) the neurophysiological level; (ii) the descriptive higher-order practical skill level; and (iii) the logical level of integration. It is argued that Searle's logical framework is found plausible, but that more work is needed to better understand the background conditions of skilled movement in terms of neurophysiological capacities and practical skills from both scientific and philosophical perspectives.

Mobile health devices pose novel questions at the intersection of philosophy and technology. Many such applications not only collect sensitive data, but also aim at persuading users to change their lifestyle for the better. A major concern is that persuasion is paternalistic as it intentionally aims at changing the agent’s actions, chipping away at their autonomy. This worry roots in the philosophical conviction that perhaps the most salient feature of living autonomous lives is displayed via agency as opposed to patiency—our (...) lives go well in virtue of what we do, rather than what happens to us. Being persuaded by a device telling us how to conduct our lives seemingly renders the agent passive, an inert recipient of technological commands. This agential bias, however, has led to a marginalization of patiential characteristics that are just as much part of our lives as are agential characteristics. To appreciate the inherent interlocking of acting and being acted upon, it is vital to acknowledge that agency and patiency are correlates, not mutually exclusive opposites. Furthermore, it is unclear whether an action can only count as agential so long as its causes are internal. Drawing on the extended mind and extended will framework, I argue that mHealth applications merely serve as volitional aids to the agent’s internal cognition. Autonomously set goals can be achieved more effectively via technology. To be persuaded by an mHealth device does not mainly—let alone exclusively—emphasize patiency; on the contrary, it can be an effective tool for technologically enhancing agency. (shrink)

In this paper I argue that coming into existence can benefit (or harm) aperson. My argument incorporates the comparative claim that existence canbe better (or worse) for a person than never existing. Since these claimsare highly controversial, I consider and reject a number of objectionswhich threaten them. These objections raise various semantic, logical,metaphysical and value-theoretical issues. I then suggest that there is animportant sense in which it can harm (or benefit) a person not to comeinto existence. Again, I consider and (...) reject some objections. Finally, Ibriefly consider what the conclusions reached in this paper imply for ourmoral obligations to possible future people. (shrink)

The present paper unravels ontological and normative conditions of personhood for the purpose of critiquing ‘Cognitivist Views’. Such views have attracted much attention and affirmation by presenting the ontology of personhood in terms of higher-order cognition on the basis of which normative practices are explained and justified. However, these normative conditions are invoked to establish the alleged ontology in the first place. When we want to know what kind of entity has full moral status, it is tempting to establish an (...) ontology that fits our moral intuitions about who should qualify for such unique normative standing. But this approach conflates personhood’s ontology and normativity insofar as it stresses the primacy of the former while implicitly presupposing the latter; it thereby suffers from a ‘Normative Fallacy’ by inferring from ‘ought’ to ‘is’. Following my critique of Cognitivism, I sketch an alternative conception, contending that, whereas the Cognitivist ontology of personhood presupposes the normative, a social ontology is constituted by it. In due consideration of evidence from developmental psychology, the social embeddedness of persons—manifested in the ability of taking a ‘second-person stance’—is identified as a key feature of personhood that precedes higher-order cognition, and is directly linked to basic normative concerns.

In a recent, thought-provoking paper Adam Elga argues against unsharp – e.g., indeterminate, fuzzy and unreliable – probabilities. Rationality demands sharpness, he contends, and this means that decision theories like Levi's, Gärdenfors and Sahlin's, and Kyburg's, though they employ different decision rules, face a common, and serious, problem. This article defends the rule to maximize minimum expected utility against Elga's objection.

Nass’ and Reeves’ media equation paradigm within human–computer interaction challenges long-held assumptions about how users approach computers. Given a rudimentary set of cues present in the system’s design, users are said to unconsciously treat computers as genuine interactants—extending rules of politeness, biases and human interactive conventions to machines. Since the results have wide-ranging implications for HCI research methods, interface design and user experiences, researchers are hard-pressed to experimentally verify the paradigm. This paper focuses on the methodology of attributing the necessary (...) social cues to the agent, a core aspect of the experimental design of studies dealing with the media equation. A typology of experimental anthropomorphisms is developed, allowing an assessment of how the differing axiomatic assumptions affect the relevance of the results for an evaluation of the paradigm. The paper concludes with a series of arguments in favour of one particular anthropomorphism type for researching the media equation. (shrink)

Some habits are vital to who we are in that they shape both our self-perception and how we are seen by others. This is so, I argue, because there is a constitutive link between what I shall call ‘identity-shaping habits’ and narrative agency. Identity-shaping habits are paradigmatically acquired and performed by persons. The ontology of personhood involves both synchronic and diachronic dimensions which are structurally analogous to the synchronic acquisition and the diachronic performance of habits, and makes persons distinctly suitable (...) to being shaped by habits. Since habits differ vastly in their scope, I develop a conceptualization that carves out defining features of identity-shaping habits. Such habits, I venture, fundamentally alter a person’s embodiment such that the alterations to their psychological and physiological make-up vitally inform their persistence—if not metaphysically, then at least practically by crucially shaping one’s narrative agency.

The Ethical Question asks whether ethical values in artworks determine their aesthetic value and, if so, how. I argue that the question is ambiguous between a direct and an indirect reading. I show how the indirect reading is philosophically uninteresting because it has an obvious answer: a view called ‘immoralism’. I also show how most of the significant figures in the relevant literature address the indirect form of the question anyway—needlessly, if I am right. Finally, I consider whether some version (...) of the indirect question is more philosophically interesting, connecting it to the so-called ‘qua problem’. I attempt to give clarity to the discussion by applying work on the virtues and vices of explanations. (shrink)

This paper discusses proof-theoretic semantics, the project of specifying the meanings of the logical constants in terms of rules of inference governing them. I concentrate on Michael Dummett’s and Dag Prawitz’ philosophical motivations and give precise characterisations of the crucial notions of harmony and stability, placed in the context of proving normalisation results in systems of natural deduction. I point out a problem for defining the meaning of negation in this framework and prospects for an account of the meanings of (...) modal operators in terms of rules of inference. (shrink)

In this paper, I discuss phenomenological and logical characteristics of skilled behaviour in sport. The paper comprises two parts. The first describes phenomenological characteristics of skilled behaviour through Timothy Gallwey’s two playing modes and Maurice Merleau-Ponty’s distinction between abstract and concrete movement. The second logical part introduces the concept of intentionality and the distinction Sean Kelly makes between cognitive and motor intentionality. I discuss how this distinction fits the phenomenological characteristics established in the first part of the paper. My argument (...) is that the logical structure of cognitive intentionality fits phenomenological characteristics of abstract movement, whereas the logical structure of motor intentionality fits phenomenological characteristics of concrete movements.

In "Rethinking Sadomasochism," Patrick Hopkins challenges the "radical" feminist claim that sadomasochism is incompatible with feminism. He does so by appeal to the notion of "simulation." I argue that Hopkins's conclusions are generally right, but they cannot be inferred from his "simulation" argument. I replace Hopkins's "simulation" with Kendall Walton's more sophisticated theory of "make-believe." I use this theory to better argue that privately conducted sadomasochism is compatible with feminism.

We treat the classical dynamics of the hydrogen atom in perpendicular electric and magnetic fields as a celestial mechanics problem. By expressing the Hamiltonian in appropriate action–angle variables, we separate the different time scales of the motion. The method of averaging then allows us to reduce the system to two degrees of freedom, and to classify the most important periodic orbits.

Empathy facilitates everyday social interactions and has often been linked in the literature to prosocial behavior. Robust evidence has been found for a positive relationship between experiencing empathy and behaving prosocially. However, empathy, and the empathy–prosocial behavior relationship in particular, has been studied mostly in combination with negative emotions. Less research has been conducted on empathy for positive emotions, and the link between positive empathy and displayed prosocial behavior has not been intensively investigated so far. The purpose of the present (...) article is thus twofold: first, we review and summarize research evidence on empathy for positive emotions, and second, we propose that people’s motivation to maintain an experienced positive affect is a viable mechanism linking positive empathy and prosocial behavior.

This paper discusses what the so-called Priority View implies regarding possible people. It is argued that this view is plausible when applied to fixed populations, but that, when applied to the issue of possible people, it faces certain difficulties. If it is claimed that possible people fall within the scope of the Priority View, we are led to the repugnant conclusion at a faster pace than we are by, e.g., utilitarianism. And if it is claimed that possible people do not (...) fall within the scope of the Priority View, we shall have to combine this view with a different view in order to avoid certain counter-intuitive judgements. Such a combined view, however, leads to intransitivities. At the end of the paper, I discuss what these conclusions imply regarding both the Priority View and our moral obligations to possible people. (shrink)

Emergence is a universal phenomenon that can be defined mathematically in a very general way. This is useful for the study of scientifically legitimate explanations of complex systems, here defined as hyperstructures. A requirement is that the observation mechanisms are considered within the general framework. Two notions of emergence are defined, and specific examples of these are discussed.

This contribution traces the parallel development of two distinct approaches to peasant agroecological education: the peasant-to-peasant horizontal method that disseminated across Mesoamerica and the Caribbean beginning in the 1970s, and the political-agroecological training schools of combined consciousness-building and skill-formation that have been at the heart of the educational processes of member organizations of La Via Campesina since the 1990s. Applying a theoretical framework that incorporates territorial struggle, agroecology and popular education, we examine spatial and organizational aspects of each of these (...) models for peasant education and movement-building. Recognizing that the models, their respective contexts, and the dialectical relationships therein have been in constant evolution, we share findings on the movement-place as a territorial system with socio-historical subjectivity, that is, peasant movements as territorially-embedded, collective historical actors. This leads to some conclusions in moving past educational theory that has centered upon individual subjects, and approaching a conception of territory as a subject of learning processes. (shrink)

A crucial task for sport research is to understand and explain the processes and conditions underlying skillful motor behavior. One way to account for these processes and conditions is to describe and analyze the distinct stages a learner goes through when acquiring a skill. This article starts by elaborating one of the most dominant conceptualizations of motor skills in sport, namely the information-processing approach to skills, and then it briefly recapitulates Hubert and Stuart Dreyfus’s phenomenology of skill acquisition. In a (...) second part, these two distinct perspectives of skills are discussed. The discussion progresses in a dialectical way where the author alternately argues for both perspectives. Emerging from this dialectic, the article presents two arguments for why Dreyfus’s phenomenology of skill acquisition is superior to the information-processing approach. (shrink)

Need-based justice is an important ingredient for a pluralistic theory of justice. But how can need-based justice be measured? I will argue that need-based justice cannot be measured by measuring need-satisfaction. This is because need-based justice does not only depend on need-satisfaction, but also on opportunities to avoid or at least mitigate undersupply. Depending on these opportunities, one and the same degree of undersupply can be unjust to different degrees. In this article, I establish a number of desiderata that a (...) measure of need-based justice has to comply with. Resulting measures treat avoidable undersupply as the main source of injustice.

This paper draws attention to a proof of the necessity of identity given by Arthur Prior. In its simplicity, it is comparable to a proof of Quine's, popularised by Kripke, but it is slightly different. Prior's Polish notation is transcribed into a more familiar idiom. Prior's proof is followed by a proof of the necessity of difference, possibly the first such proof in the literature, which is also repeated here and transcribed. The paper concludes with a brief discussion of Prior's (...) views on identity and difference over time. (shrink)

This chapter examines autonomism. Autonomism is roughly the view that an artwork’s ethical properties do not bear on its aesthetic or artistic value. The author sketches some of the view’s history before describing various versions of it defended over the last quarter-century. These are divided into ‘radical’, ‘robust’, and ‘moderate’ forms of autonomism. The author considers the strengths and weaknesses of each. The author also devotes some space to the ‘interactionist’ views against which contemporary autonomism is typically opposed. In doing (...) so, he considers the so-called ‘qua problem’ at some length, as well its bearing on these various autonomist positions. (shrink)

Some things that we take to be the case in a fictional work are never made explicit by the work itself. For instance, we assume that Sherlock Holmes does not have a third nostril, that he wears underpants and that he has never solved a case with a purple gnome, even though neither of these things is ever mentioned in the narration. This article argues that examples like these can be accounted for through the same content-enriching reasoning that we employ (...) when confronted with non-fictional discourse, with the important difference that fictional discourse essentially involves pretence. Fictional discourse works in much the same way as non-fictional discourse, and what is conveyed without being stated can accordingly be explained through familiar pragmatic mechanisms. It is argued that this account carries some distinct advantages over competing views. (shrink)

In this paper, we consider a few actual cases of mnemonic strategies among older subjects (older than 65). The cases are taken from an ethnographic study, examining how elderly adults cope with cognitive decline. We believe that these cases illustrate that the process of remembering in many cases involve a complex distributed web of processes involving both internal or intracranial and external sources. Our cases illustrate that the nature of distributed remembering is shaped by and subordinated to the dynamic characteristics (...) of the on-going activity and to our minds suggest that research on memory and distributed cognition should focus on the process of remembering through detailed descriptions and analysis of naturally occurring situations.

Roughly, according to conditional egalitarianism, equality is non-instrumentally valuable, but only if it benefits at least one individual. Some political theorists have argued that conditional egalitarianism has the important virtue that it allows egalitarians to avoid the so-called objection. However, in the present article I argue that conditional egalitarianism does not offer the egalitarian a plausible escape route from this objection. First, I explain the levelling down objection and suggest some particular concerns from which it derives its force. Then I (...) provide a more precise definition of conditional egalitarianism. Finally, I give two arguments against this principle. According to the first, it violates the transitivity of the betterness relation (or more specifically, ). According to the second, there is no plausible explanation of why equality must benefit at least one individual in order to be non-instrumentally valuable. (shrink)

This paper formulates a bilateral account of harmony that is an alternative to one proposed by Francez. It builds on an account of harmony for unilateral logic proposed by Kürbis and the observation that reading the rules for the connectives of bilateral logic bottom up gives the grounds and consequences of formulas with the opposite speech act. I formulate a process I call 'inversion' which allows the determination of assertive elimination rules from assertive introduction rules, and rejective elimination rules from (...) rejective introduction rules, and conversely. It corresponds to Francez's notion of vertical harmony. I also formulate a process I call 'conversion', which allows the determination of rejective introduction rules from assertive elimination rules and conversely, and the determination of assertive introduction rules from rejective elimination rules and conversely. It corresponds to Francez's notion of horizontal harmony. The account has a number of features that distinguish it from Francez's. (shrink)

The last decades have seen a rising philosophical interest in the phenomenology of skill acquisition. One central topic in this work is the relation between the athlete's background capacities and foreground attention as an invariant feature of skilful movements. The purpose of this paper is to examine further this gestalt relation from the perspective of Merleau-Ponty's phenomenological account of embodied learning and a classical notion from philosophy of sport, namely ?sweet tension of uncertainty of outcome?. In the first part we (...) will explicate how Merleau-Ponty understands embodied learning as a form of gestalt switch that allows the athlete to perceive the world more meaningfully in relation to an ongoing movement project. That is, a skilled athlete perceives more and better opportunities for actions. In the second part, we revisit the classical notion of ?sweet tension of uncertainty of outcome? developed by Kretchmar. This phrase is attributed to the indeterminate back and forth rallies between sport contestants, and to persons facing a sport situation that produces an ambiguity as to whether one will succeed in one's task. In the third part, we then juxtapose Merleau-Ponty's notion of embodied learning and the notion of sweet tension from philosophy of sport in order to draw out the relations between the two notions. In addition, in much of the philosophical work on skill acquisition (for instance in Merleau-Ponty and his much-cited commentator, Hubert Dreyfus) the distinction between everyday skills (such as walking and opening doors) and sport skills is collapsed. Our discussion aims to show that by introducing the notion of ?sweet tension? to the literature on phenomenology of skill acquisition, we are able to highlight a phenomenological difference between everyday skills and sport skills.

Ian Rumfitt has proposed systems of bilateral logic for primitive speech acts of assertion and denial, with the purpose of ‘exploring the possibility of specifying the classically intended senses for the connectives in terms of their deductive use’ : 810f). Rumfitt formalises two systems of bilateral logic and gives two arguments for their classical nature. I assess both arguments and conclude that only one system satisfies the meaning-theoretical requirements Rumfitt imposes in his arguments. I then formalise an intuitionist system of (...) bilateral logic which also meets those requirements. Thus Rumfitt cannot claim that only classical bilateral rules of inference succeed in imparting a coherent sense onto the connectives. My system can be extended to classical logic by adding the intuitionistically unacceptable half of a structural rule Rumfitt uses to codify the relation between assertion and denial. Thus there is a clear sense in which, in the bilateral framework, the difference between classicism and intuitionism is not one of the rules of inference governing negation, but rather one of the relation between assertion and denial.
