In this work we survey reports on selected severe storms of the 17th century. Specifically, we investigate a severe storm which was accompanied by a ball lightning phenomenon in Cornwall (UK) in 1640. The “fiery Ball”, which reportedly made a “ter[r]ible sound”, entered the church, broke stones and smashed windows. It made holes in stone walls and injured about 14 people. Furthermore, we report on a 1672 storm in Bedford (UK) that tore down houses, blew down stone walls and uprooted (...) trees. We also examine two severe thunderstorms that tore off roofs and uprooted trees in Oxfordshire (UK) and Blois (F) in 1680. In Oxfordshire, hailstone killed farm animals, and later lightning caused a fire, which damaged houses and burned down barns. In Blois, houses were torn down by the wind, eight parishes were ruined by hail (hailstone were the size of a “man’s fist”). Furthermore, houses were damaged and glass windows were shattered. Based on various primary sources, we discuss the impact of these severe storms on society. Moreover, we briefly discuss how people perceived atmospheric phenomena like storms, tornadoes, and hail. Finally, we discuss selected key issues of investigating historical severe storms. (shrink)

In this paper, I discuss how information theory has been used in the study of animal communication, as well as how these uses are justified. Biologists justify their use of Shannon’s information measures by the work they do in allowing for comparisons between different organisms and because they measure a quantity that is purported to be important for natural selection. I argue that there are problems with both sorts of justification. To make these difficulties clear, I focus on the use (...) of Shannon’s information measures to quantify the amount of information transmitted by the fire ant’s odor trail and the honeybee’s waggle dance. Both of these systems are relatively simple and well understood, and the application of Shannon’s information measure to these systems initially seemed very promising and relatively straightforward. They are therefore particularly suitable for revealing the benefits and difficulties of applying Shannon’s information measures to biological systems in general, and animal communication systems in particular.

How does the brain generate our experience of being in control over our actions and their effects? Here, we argue that the perception of events as self-caused emerges from a comparison between anticipated and actual action-effects: if the representation of an event that follows an action is activated before the action, the event is experienced as caused by one’s own action, whereas in the case of a mismatch it will be attributed to an external cause rather than to the self. (...) In a subliminal priming paradigm we show that participants overestimated how much control they had over objectively uncontrollable stimuli, which appeared after free- or forced-choice actions, when a masked prime activated a representation of the stimuli immediately before each action. This prime-induced control-illusion was independent from whether primes were consciously perceived. Results indicate that the conscious experience of control is modulated by unconscious anticipations of action-effects. (shrink)

In view of the numerous accounting and corporate scandals associated with various forms of moral misconduct and the recent financial crisis, economics and business programs are often accused of actively contributing to the amoral decision making of their graduates. It is argued that theories and ideas taught at universities engender moral misbehavior among some managers, as these theories mainly focus on the primacy of profit-maximization and typically neglect the ethical and moral dimensions of decision making. To investigate this criticism, two (...) overlapping effects must be disentangled: the self-selection effect and the treatment effect. Drawing on the concept of moral judgment competence, we empirically examine this question with a sample of 1773 bachelor’s and 501 master’s students. Our results reveal that there is neither a self-selection nor a treatment effect for economics and business studies. Moreover, our results indicate that—regardless of the course of studies—university education in general does not seem to foster students’ moral development. (shrink)

While interdisciplinarity is not a new concept, the political and discursive mobilisation of interdisciplinarity is. Since the 1990s, this movement has intensified, and this has affected central funding bodies so that interdisciplinarity is now a de facto requirement in successful grant application. As a result, the literature is ripe with definitions, taxonomies, discussions and other attempts to grasp and define the concept of interdisciplinarity. In this paper, we explore how strategic demands for interdisciplinarity meet, interact with and change local research (...) practices and results of higher education and research. Our aim is to question and trace the consequences of applying the slippery and difficult term interdisciplinarity in research. The paper is based on ethnographic fieldwork in a Danish interdisciplinary research programme, where we observed and analysed practices of writing, publishing, collaboration and educational development in five different research projects. We show how the call for interdisciplinarity was mobilised in a way that rendered the incentives and motives behind the programme unclear. Furthermore, we argue that the absence of clear definitions and assessment criteria produced a dominant, all-inclusive, but vague, configuration of interdisciplinarity that affected the research outcome, and ultimately, promoted and reproduced the existing monodisciplinary research and power structures.

In this paper an approach to the exhaustive interpretation of answers is developed. It builds on a proposal brought forward by Groenendijk and Stokhof (1984). We will use the close connection between their approach and McCarthy's (1980, 1986) predicate circumscription and describe exhaustive interpretation as an instance of interpretation in minimal models, well-known from work on counterfactuals (see for instance Lewis (1973)). It is shown that by combining this approach with independent developments in semantics/pragmatics one can overcome certain limitations of (...) Groenenedijk and Stokhof's (1984) proposal. In the last part of the paper we will provide a Gricean motivation for exhaustive interpretation building on work of Schulz (to appear) and van Rooij and Schulz (2004). (shrink)

When it comes to improving the health of the general population, mHealth technologies with self-monitoring and intervention components hold a lot of promise. We argue, however, that due to various factors such as access, targeting, personal resources or incentives, self-monitoring applications run the risk of increasing health inequalities, thereby creating a problem of social justice. We review empirical evidence for “intervention-generated” inequalities, present arguments that self-monitoring applications are still morally acceptable, and develop approaches to avoid the promotion of health inequalities (...) through self-monitoring applications.

Legal decision-support systems have the potential to improve access to justice, administrative efficiency, and judicial consistency, but broad adoption of such systems is contingent on development of technologies with low knowledge-engineering, validation, and maintenance costs. This paper describes two approaches to an important form of legal decision support—explainable outcome prediction—that obviate both annotation of an entire decision corpus and manual processing of new cases. The first approach, which uses an attention network for prediction and attention weights to highlight salient case (...) text, was shown to be capable of predicting decisions, but attention-weight-based text highlighting did not demonstrably improve human decision speed or accuracy in an evaluation with 61 human subjects. The second approach, termed semi-supervised case annotation for legal explanations, exploits structural and semantic regularities in case corpora to identify textual patterns that have both predictable relationships to case decisions and explanatory value.

This paper deals with the truth conditions of conditional sentences. It focuses on a particular class of problematic examples for semantic theories for these sentences. I will argue that the examples show the need to refer to dynamic, in particular causal laws in an approach to their truth conditions. More particularly, I will claim that we need a causal notion of consequence. The proposal subsequently made uses a representation of causal dependencies as proposed in Pearl (2000) to formalize a causal (...) notion of consequence. This notion inserted in premise semantics for counterfactuals in the style of Veltman (1976) and Kratzer (1979) will provide a new interpretation rule for conditionals. I will illustrate how this approach overcomes problems of previous proposals and end with some remarks on remaining questions. (shrink)

Micro-phenomenology is an interview and analysis method for investigating subjective experience. As a research tool, it provides detailed descriptions of brief moments of any type of subjective experience and offers techniques for systematically comparing them. In this article, we use an auto-ethnographic approach to present and explore the method. The reader is invited to observe a dialogue between two authors that illustrates and comments on the planning, conducting and analysis of a pilot series of five micro-phenomenological interviews. All these interviews (...) asked experienced researchers of micro-phenomenology to browse their memories to identify one successful and one challenging instance of working with micro-phenomenology. The interview then focused on this reflective task to investigate whether applying the method to itself might reveal quality criteria. The article starts by presenting a shortened and edited version of the first of these interviews. Keeping the dialogue format, we then outline the micro-phenomenological analysis procedure by demonstrating its application to part of this data and corresponding passages of other interviews. We focus on one unexpected finding: interviewed researchers judge the quality of an interview in part based on a connection or contact between interviewer and interviewee. We discuss these results in the context of the means and intentions of the method and suggest avenues for future research. (shrink)

In this paper, a pragmatic approach to the phenomenon of free choice permission is proposed. Free choice permission is explained as due to taking the speaker (i) to obey certain Gricean maxims of conversation and (ii) to be competent on the deontic options, i.e. to know the valid obligations and permissions. The approach differs from other pragmatic approaches to free choice permission in giving a formally precise description of the class of inferences that can be derived based on these two (...) assumptions. This formalization builds on work of Halpern and Moses (1984) on the concept of ‘only knowing’, generalized by Hoek et al., (1999, 2000), and Zimmermann’s (2000) approach to competence. (shrink)

We investigated the impact of attention during encoding on later retrieval. During study, participants read some words aloud and named the print color of other words aloud . Then one of two memory tests was administered. The explicit test—recognition—required conscious recollection of whether a word was studied. Previously read words were recognized more accurately than were previously color named words. This contrasted sharply with performance on the implicit test—repetition priming in lexical decision. Here, words that were color named during study (...) showed priming equivalent to words that were read during study; both were responded to faster than unstudied words. Thus, an attentional manipulation during study had a strong effect on an explicit test of memory, but almost no effect on an implicit test. Focal attention during study is crucial for remembering consciously but not necessarily for remembering without awareness. (shrink)

This study explores the attitude of German psychiatrists in leading positions towards joint crisis plans and psychiatric advance directives. This topic was examined by contacting 473 medical directors of German psychiatric hospitals and departments. They were asked to complete a questionnaire developed by us. That form contained questions about the incidence and acceptance of joint crisis plans and psychiatric advance directives and previous experiences with them. 108 medical directors of psychiatric hospitals and departments responded . Their answers demonstrate that in (...) their hospitals these documents are rarely used. Among the respondents, joint crisis plans are more accepted than psychiatric advance directives. There is a certain uncertainty when dealing with these instruments. Our main conclusion is that German psychiatry needs an intensified discussion on the use of instruments for patients to constitute procedures for future critical psychiatric events. For this purpose it will be helpful to collect more empirical data. Furthermore, the proposal of joint crisis plans in psychiatric hospitals and departments should be discussed as well as the possibility of consulting an expert during the preparation of a psychiatric advance directive.

In order for artificial intelligent systems to interact naturally with human users, they need to be able to learn from human instructions when actions should be imitated. Human tutoring will typically consist of action demonstrations accompanied by speech. In the following, the characteristics of human tutoring during action demonstration will be examined. A special focus will be put on the distinction between two kinds of motion events: path-oriented actions and manner-oriented actions. Such a distinction is inspired by the literature pertaining (...) to cognitive linguistics, which indicates that the human conceptual system can distinguish these two distinct types of motion. These two kinds of actions are described in language by more path-oriented or more manner-oriented utterances. In path-oriented utterances, the source, trajectory, or goal is emphasized, whereas in manner-oriented utterances the medium, velocity, or means of motion are highlighted. We examined a video corpus of adult–child interactions comprised of three age groups of children—pre-lexical, early lexical, and lexical—and two different tasks, one emphasizing manner more strongly and one emphasizing path more strongly. We analyzed the language and motion of the caregiver and the gazing behavior of the child to highlight the differences between the tutoring and the acquisition of the manner and path concepts. The results suggest that age is an important factor in the development of these action categories. The analysis of this corpus has also been exploited to develop an intelligent robotic behavior—the tutoring spotter system—able to emulate children's behaviors in a tutoring situation, with the aim of evoking in human subjects a natural and effective behavior in teaching to a robot. The findings related to the development of manner and path concepts have been used to implement new effective feedback strategies in the tutoring spotter system, which should provide improvements in human–robot interaction.

This paper examines whether adults can adapt to novel accents of their native language that contain unfamiliar context-dependent phonological alternations. In two experiments, French participants listen to short stories read in accented speech. Their knowledge of the accents is then tested in a forced-choice identification task. In Experiment 1, two groups of listeners are exposed to newly created French accents in which certain vowels harmonize or disharmonize, respectively, to the rounding of the preceding vowel. Despite the cross-linguistic predominance of vowel (...) harmony over disharmony, the two groups adapt equally well to both accents, suggesting that this typological difference is not reflected in perceptual learning. Experiment 2 further explores the mechanism underlying this type of phonological learning. Participants are exposed to an accent in which some vowels harmonize and others disharmonize, yielding an increased featural complexity. They adapt less well to this regularity, showing that adaptation to novel accents involves feature-based inferences. (shrink)

Research on sustainability assurance is still in its beginnings. One of the key questions in this field that also is of the highest practical relevance is concerned with the quality of the assurance process. However, a common understanding of assurance quality and how it should be measured is still missing. We try to close this gap by building on the financial audit literature. We introduce a definition of assurance quality that comprises two key aspects: the depth of the assurance process (...) and the breadth of the assurance statement. Based on prior research, we hypothesize that a firm’s sustainability performance is related to the depth of the assurance process, while the type of the assurance provider, more precisely the affiliation to the accounting profession, is related to the breadth of the assurance statement. Results for a sample of 122 European firms reveal a negative relationship between sustainability performance and assurance process depth as well as between the affiliation to the accounting profession and assurance statement breadth. Thus, we find evidence that poor sustainability performers ask for in-depth assurance services, most likely as a means to enhance their internal sustainability-related processes and systems. Assurance providers that do not belong to the accounting profession in turn are associated with broader assurance statements. (shrink)

In spite of their striking differences with real-life perception, films are perceived and understood without effort. Cognitive film theory attributes this to the system of continuity editing, a system of editing guidelines outlining the effect of different cuts and edits on spectators. A major principle in this framework is the 180° rule, a rule recommendation that, to avoid spectators’ attention to the editing, two edited shots of the same event or action should not be filmed from angles differing in a (...) way that expectations of spatial continuity are strongly violated. In the present study, we used high-density EEG to explore the neural underpinnings of this rule. In particular, our analysis shows that cuts and edits in general elicit early ERP component indicating the registration of syntactic violations as known from language, music, and action processing. However, continuity edits and cuts-across the line differ from each other regarding later components likely to be indicating the differences in spatial remapping as well as in the degree of conscious awareness of one's own perception. Interestingly, a time–frequency analysis of the occipital alpha rhythm did not support the hypothesis that such differences in processing routes are mainly linked to visual attention. On the contrary, our study found specific modulations of the central mu rhythm ERD as an indicator of sensorimotor activity, suggesting that sensorimotor networks might play an important role. We think that these findings shed new light on current discussions about the role of attention and embodied perception in film perception and should be considered when explaining spectators’ different experience of different kinds of cuts.

In the current discussion of criminal legislation and jurisdiction, two differing concepts of criminal law have become more and more prominent: “Criminal law for the citizen“ and “criminal law for the enemy”. These two concepts have been developed by G. Jakobs (Bonn), who not only was the first to recognise the emergence of a new type of criminal law “for the enemy”, but also provided a theoretical background for this notion. The article will explain Jacobs’ theory and discuss its capacity (...) to convince from the perspective of a liberal legal philosophy. Based on the work of I. Kant, the author reflects first on Jakobs’ underlying differentiation between “individual” (as a naturally determined being that lives for the enjoyment of pleasure and the avoiding of pains) and “person” (as a subject capable of reflecting on right or wrong). Secondly, the author will consider and criticise Jakobs’ notions of prevention and punishment. Finally, it will be shown that there is no way of justifying a “criminal law for the enemy” in a liberal state. (shrink)

This article critically reflects upon the concept of “criminal offence” currently being discussed in Germany. One of the opinions that is critically reviewed argues that the criminalisation of behaviour (Verhalten) has to be legitimated independently of the criminal sanction (Sanktionsnorm). However, the author of this article argues that the concept of what a criminal offence is cannot be developed without taking into account what the reasons for punishment are.

Zusammenfassung Wie kann Gottes Gegenwart trotz ihrer Verborgenheit wahrgenommen werden? In dem folgenden Beitrag möchte ich zeigen, wie Simone Weil die Erfahrungen der Verborgenheit und der Abwesenheit Gottes als Signatur des Unglücks und der Entwurzelung der Menschen in der Moderne analysiert. Des Weiteren wird dargestellt, wie Simone Weil vor diesem Hintergrund mit einer kreuzestheologischen Denkfigur reflektiert, wie die Gottesliebe in besonderer Weise im Unglück verborgen anwesend sein kann, trotz Erfahrung der Abwesenheit Gottes. Hier schließt sich die erkenntnistheoretische Frage nach der (...) Wahrnehmbarkeit der verborgenen Gegenwart Gottes an. So soll ausgeführt werden, wie Simone Weil aufzeigt, wie durch ästhetische Formen der Schönheit und Ordnung der Welt, durch ethische Formen von Nächstenliebe und Freundschaft und durch die religiöse Formen in Liturgie und Gebet als höchster Form der Aufmerksamkeit die verborgen gegenwärtige Gottesliebe indirekt wahrgenommen werden kann. Dies spricht schließlich für eine andere Deutung der Verborgenheit Gottes als im sog. Verborgenheitsargument von J. L. Schellenberg, mit dem von der Verborgenheit auf die Nichtexistenz Gottes geschlossen wird. (shrink)

Overweight and obesity among children and adolescents are global problems of our time. Due to their authority and role modeling, parents play an essential part in the efficacy of prevention and intervention programs. This study assessed the barriers that parents of overweight/obese children face in preventive and interventional health care utilization. Sixteen parents were qualitatively interviewed. A content analysis was performed, and barriers to change were allocated to their stage of change according to the transtheoretical model. Among the main barriers (...) is the underestimation of health risks caused by overweight/obesity in association with diminished problem awareness. Parents seem not necessarily in need of theoretical knowledge for prevention and interventions. They do however need support in evaluating the weight status of their child and the knowledge of whom to turn to for help as well as specific and hands-on possibilities for change. The results extend past studies by adding specific barriers to change that parents commonly experience. Possibilities to address these barriers, e.g., through trainings at the pediatric practice or adoption of conversation techniques, are discussed. Future studies might identify subgroups experiencing specific barriers and thus be able to address these in an individualized way. (shrink)

Intervening in the multidisciplinary debate on emotion, Tropes of Transport offers a fresh analysis of Hegel’s work that becomes an important resource for Pahl’s cutting-edge theory of emotionality. If it is usually assumed that the sincerity of emotions and the force of affects depend on their immediacy, Pahl explores to what extent mediation—and therefore a certain degree of manipulation but also of sympathy—is constitutive of emotionality. Hegel serves as a particularly helpful interlocutor not only because he offers a sophisticated analysis (...) of mediation, but also because, rather than locating emotion in the heart, he introduces impersonal tropes of transport, such as trembling, release, and shattering.

The postsecular turn within feminist theory refers to a renewed attention to religion within feminist scholarship. However, rather than conceptualizing the postsecular as a new moment within feminist theorizing that breaks with a previous trend of secular feminism, this article stresses that it is important to recognize the long history of coexistence and contestations between religious and secular feminist approaches. In this article, the different reception histories of the story of Sojourner Truth are examined to elucidate and reflect on the (...) complicated relationship of the religious and the secular within feminist scholarship. Three different types of feminist theoretical engagement with the story of Sojourner Truth are examined and contrasted: the implicitly secular use of the story of Sojourner Truth in black feminist scholarship and theorizing of intersectionality, the explicitly religious interpretations found in the work of feminist and womanist theologians, and the deconstructive reading by Donna Haraway. In discussing and comparing these different engagements with the story of Sojourner Truth, it is stressed that the boundaries between the religious and the secular are perhaps less clear-cut than initially imagined, and that a dialogue between secular and religious feminist approaches is very fruitful. The article closes by examining how the complex intersections of gender, religion and race in the story of Sojourner Truth can be connected to the contemporary theorizing on the racialization of religion within critical race scholarship.

This article focusses on the social and legal implications that blockchain technology brings about, not only due to its ideological framework, but also, and especially, due to the concept of law it inaugurates. Thus, this article claims, that, by interlocking technological and legal structures, blockchain technology initiates a profound displacement of legal symbolics and imaginaries. It shows how blockchain law, by emancipating itself from three essential dimensions of law—language, territory, and the body—implies a profound disruption of how we perceive law (...) and its legitimacy. Starting with an overview of the technological details of blockchain, the paper then addresses its ideological context and traces the underlying ideas, values and functions and their relation with—and impact on—the general perception of law and legal issues. By critically assessing the claim that blockchain will liberate the subject from any heteronymic constraints, this paper analyses to what extent this technology has social and legal implications that reach far beyond its virtual, purely blockchain-related scope of applications—and why this technology should matter to us all.

5‐methylcytosine (5mC) was long thought to be the only enzymatically created modified DNA base in mammalian cells. The discovery of 5‐hydroxymethylcytosine, 5‐formylcytosine, and 5‐carboxylcytosine as reaction products of the TET family 5mC oxidases has prompted extensive searches for proteins that specifically bind to these oxidized bases. However, only a few of such “reader” proteins have been identified and verified so far. In this review, we discuss potential biological functions of oxidized 5mC as well as the role the presumed reader proteins (...) may play in interpreting the genomic signals of 5mC oxidation products.

Children develop language and communication skills through interaction with adults and other children. This study therefore focuses on two interdependent issues: the effect of philosophizing with children on children’s language development and the speech acts of teachers and children in philosophical enquiries. As part of a before-after test with the “Hamburger Verfahren zur Analyse des Sprachstandes Fünfjähriger”, weekly philosophical discussions were undertaken with a test class over a period of six months. The central findings are that the philosophising children developed (...) significantly higher language ability compared with a non-philosophising control class in two areas, namely general performance in discussion and the use of more sophisticated connectors. A further part of the study compared the speech acts of the children and their pre-school teacher in the context of philosophical discussion with their speech acts in a different dialogic situation. This showed that philosophical questions from the pre-school teacher led to the production of particularly complex language by the children. Complex speech acts involve the use of higher-level verb structures and connectors. These are necessary in order to reason and act as a citizen agent and are supported by philosophising with children, as this study shows. (shrink)
