    The Use of Information Theory in Biology: Lessons from Social Insects.Jessica Pfeifer - 2006 - Biological Theory 1 (3):317-330.
    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 (...)

    IT IS SHOWN IN DETAIL THAT RECENT ACCOUNTS FAIL TO DISTINGUISH BETWEEN INTENTIONALITY AND MERELY CAUSALLY DISPOSITIONAL STATES OF INORGANIC PHYSICAL OBJECTS—A QUICK ROAD TO PANPSYCHISM. THE CLEAR NEED TO MAKE SUCH A DISTINCTION GIVES DIRECTION FOR FUTURE WORK. A BEGINNING IS MADE TOWARD PROVIDING SUCH AN ACCOUNT.

    Scalable and explainable legal prediction.L. Karl Branting, Craig Pfeifer, Bradford Brown, Lisa Ferro, John Aberdeen, Brandy Weiss, Mark Pfaff & Bill Liao - 2020 - Artificial Intelligence and Law 29 (2):213-238.
    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 (...)

    Are there specific readers of oxidized 5‐methylcytosine bases?Jikui Song & Gerd P. Pfeifer - 2016 - Bioessays 38 (10):1038-1047.
    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 (...)

    Ethical concerns of nonclinical forensic witnesses and consultants.Jeffrey Pfeifer & John Brigham - 1993 - Ethics and Behavior 3 (3 & 4):329 – 343.
    Current research suggests that nonclinical forensic psychologists[sup1] are appearing increasingly more often in the legal arena. We argue that many of the ethical dilemmas that face these psychologists differ from those encountered by clinical forensic psychologists. To test the accuracy of this assertion, 37 nonclinical forensic psychologists were surveyed to identify some of the ethical issues and dilemmas they have encountered while engaging in expert testimony or pretrial consulting. Respondents were asked also about how they have resolved these ethical issues (...)

  18. Probabilistic theories of reasoning need pragmatics too: Modulating relevance in uncertain conditionals.A. J. B. Fugard, Niki Pfeifer & B. Mayerhofer - 2011 - Journal of Pragmatics 43:2034–2042.
    According to probabilistic theories of reasoning in psychology, people's degree of belief in an indicative conditional `if A, then B' is given by the conditional probability, P(B|A). The role of language pragmatics is relatively unexplored in the new probabilistic paradigm. We investigated how consequent relevance a ects participants' degrees of belief in conditionals about a randomly chosen card. The set of events referred to by the consequent was either a strict superset or a strict subset of the set of events (...)

    Transitivity in coherence-based probability logic.Angelo Gilio, Niki Pfeifer & Giuseppe Sanfilippo - 2016 - Journal of Applied Logic 14:46-64.
    We study probabilistically informative (weak) versions of transitivity by using suitable definitions of defaults and negated defaults in the setting of coherence and imprecise probabilities. We represent p-consistent sequences of defaults and/or negated defaults by g-coherent imprecise probability assessments on the respective sequences of conditional events. Moreover, we prove the coherent probability propagation rules for Weak Transitivity and the validity of selected inference patterns by proving p-entailment of the associated knowledge bases. Finally, we apply our results to study selected probabilistic (...)

  21. Reasoning About Uncertain Conditionals.Niki Pfeifer - 2014 - Studia Logica 102 (4):849-866.
    There is a long tradition in formal epistemology and in the psychology of reasoning to investigate indicative conditionals. In psychology, the propositional calculus was taken for granted to be the normative standard of reference. Experimental tasks, evaluation of the participants’ responses and psychological model building, were inspired by the semantics of the material conditional. Recent empirical work on indicative conditionals focuses on uncertainty. Consequently, the normative standard of reference has changed. I argue why neither logic nor standard probability theory provide (...)

    Competencies for a Healthy Physically Active Lifestyle: Second-Order Analysis and Multidimensional Scaling.Johannes Carl, Gorden Sudeck & Klaus Pfeifer - 2020 - Frontiers in Psychology 11.
    The physical activity-related health competence model assumes that individuals require movement competence, control competence, and self-regulation competence to lead a healthy, physically active lifestyle. Although previous research has already established some measurement factors of the three dimensions, no attempts have so far been made to statistically aggregate them on the sub-competence level. Therefore, the goal of the present study was to test two additional factors for PAHCO and subsequently model the second-order structure with two samples from the fields of rehabilitation (...)

    This book will gather contributions from international scholars with the aim of exploring the political reflection of Deleuze-Guattari’s and Foucault’s critical encounter with psychoanalytic thought: their possible connections, their divergences and the fields of reflection that this encounter opens, the problems and debates that lead Foucault and Deleuze to engage with psychoanalysis.

    We take coherence based probability logic as the basic reference theory to model human deductive reasoning. The conditional and probabilistic argument forms are explored. We give a brief overview of recent developments of combining logic and probability in psychology. A study on conditional inferences illustrates our approach. First steps towards a process model of conditional inferences conclude the paper.

  28. Experiments on Aristotle’s Thesis.Niki Pfeifer - 2012 - The Monist 95 (2):223-240.
    Two experiments (N1 = 141, N2 = 40) investigate two versions of Aristotle’s Thesis for the first time. Aristotle’s Thesis is a negated conditional, which consists of one propositional variable with a negation either in the antecedent (version 1) or in the consequent (version 2). This task allows us to infer if people interpret indicative conditionals as material conditionals or as conditional events. In the first experiment I investigate between-participants the two versions of Aristotle’s Thesis crossed with abstract versus concrete (...)

    Towards a Conceptual Framework for Conspiracy Theory Theories.Niki Pfeifer - 2023 - Social Epistemology 37 (4):510-521.
    I present a conceptual framework for classifying generalist and particularist approaches to conspiracy theories (CTs). Specifically, I exploit a probabilistic version of the hexagon of opposition which allows for systematically visualising the logical relations among basic philosophical positions concerning CTs. The probabilistic interpretation can also account for positions, which make weaker claims about CTs: e.g. instead of claiming ‘every CT is suspicious’ some theorists might prefer to claim ‘most CTs are suspicious’ and then ask about logical consequences of such claims.

    Centering and compound conditionals under coherence.A. Gilio, Niki Pfeifer & Giuseppe Sanfilippo - 2017 - In M. B. Ferraro, P. Giordani, B. Vantaggi, M. Gagolewski, P. Grzegorzewski, O. Hryniewicz & María Ángeles Gil (eds.), Soft Methods for Data Science. pp. 253-260.
    There is wide support in logic, philosophy, and psychology for the hypothesis that the probability of the indicative conditional of natural language, P(if A then B), is the conditional probability of B given A, P(B|A). We identify a conditional which is such that P(if A then B)=P(B|A) with de Finetti’s conditional event, B | A. An objection to making this identification in the past was that it appeared unclear how to form compounds and iterations of conditional events. In this paper, (...)

  32. Coherence and Nonmonotonicity in Human Reasoning.Niki Pfeifer & Gernot D. Kleiter - 2005 - Synthese 146 (1-2):93-109.
    Nonmonotonic reasoning is often claimed to mimic human common sense reasoning. Only a few studies, though, have investigated this claim empirically. We report four experiments which investigate three rules of SYSTEMP, namely the AND, the LEFT LOGICAL EQUIVALENCE, and the OR rule. The actual inferences of the subjects are compared with the coherent normative upper and lower probability bounds derived from a non-infinitesimal probability semantics of SYSTEM P. We found a relatively good agreement of human reasoning and principles of nonmonotonic (...)

  33. Formal Epistemology and the New Paradigm Psychology of Reasoning.Niki Pfeifer & Igor Douven - 2014 - Review of Philosophy and Psychology 5 (2):199-221.
    This position paper advocates combining formal epistemology and the new paradigm psychology of reasoning in the studies of conditionals and reasoning with uncertainty. The new paradigm psychology of reasoning is characterized by the use of probability theory as a rationality framework instead of classical logic, used by more traditional approaches to the psychology of reasoning. This paper presents a new interdisciplinary research program which involves both formal and experimental work. To illustrate the program, the paper discusses recent work on the (...)

    Was hält Gesellschaften zusammen? Der gefährdete Umgang mit Pluralität.Michael Reder & Hanna Pfeifer (eds.) - 2013 - Kohlhammer.
    Gesellschaften sind heute von funktionaler Ausdifferenzierung, Individualisierung und Pluralisierung gekennzeichnet. Dies lasst die Frage nach dem gesellschaftlichen Zusammenhalt virulent werden. Die Politik sucht nach Wegen, mit dieser Vielfalt umzugehen und den gesellschaftlichen Zusammenhalt zu starken. Davon zeugen Debatten uber Bildungspolitik, Sprachkurse und Leitkultur, Runde Tische oder Islamkonferenzen. Die Politische Philosophie hat in den vergangenen Jahrzehnten darauf aufmerksam gemacht, dass der Umgang mit Pluralitat einer differenzierten und multiperspektivischen Diskussion im Lichte der vielfaltigen Parameter von gesellschaftlicher Vielfalt bedarf. Was also halt Gesellschaften (...)

    Connexive Logic, Probabilistic Default Reasoning, and Compound Conditionals.Niki Pfeifer & Giuseppe Sanfilippo - 2023 - Studia Logica 112 (1):167-206.
    We present two approaches to investigate the validity of connexive principles and related formulas and properties within coherence-based probability logic. Connexive logic emerged from the intuition that conditionals of the form if not-A, thenA, should not hold, since the conditional’s antecedent not-A contradicts its consequent A. Our approaches cover this intuition by observing that the only coherent probability assessment on the conditional event $${A| \overline{A}}$$ A | A ¯ is $${p(A| \overline{A})=0}$$ p ( A | A ¯ ) = 0.

    In groupware tools, the activation of a function may affect other users who might have conflicting interests. We developed technical mechanisms to support users in resolving them. Contrary to current implementations of groupware tools, these mechanisms strengthen the position of the users who are affected by the activation of said functions. Supporting the visibility of a function's activation, and providing a channel for communication or means to intervene against the function's activation are approaches which constitute a framework to implement these (...)

    A critique of humanitarian reason: agency, power, and privilege.Chioke I'Anson & Geoffrey Pfeifer - 2013 - Journal of Global Ethics 9 (1):49-63.
    This paper offers a critical analysis of the work of western humanitarian NGOs operating in the African continent. We argue that in most cases, NGOs and their supporters are deaf to the actual wants, needs, and desires ? or, in other words, the agency ? of those they are trying to aid. We do this by first offering a series of ways of understanding the ideological commitments that inform the work of many humanitarian NGOs and those who donate to them. (...)

    UV damage and repair mechanisms in mammalian cells.Silvia Tornaletti & Gerd P. Pfeifer - 1996 - Bioessays 18 (3):221-228.
    The formation of DNA photoproducts by ultraviolet (UV) light is responsible for induction of mutations and development of skin cancer. To understand UV mutagenesis, it is important to know the mechanisms of formation and repair of these lesions. Cyclobutane pyrimidine dimers and (6–4)photoproducts are the two major classes of UV‐induced DNA lesions. Their distribution along DNA sequences in vivo is strongly influenced by nucleosomes and other DNA binding proteins. Repair of UV photoproducts is dependent on the transcriptional status of the (...)

    Balibar, citizenship, and the return of right populism.Geoff Pfeifer - 2020 - Philosophy and Social Criticism 46 (3):323-341.
    Arendt famously pointed out that only citizenship actually confers rights in the modern world. To be a citizen is to be one who has the ‘right to have rights’. Arendt’s analysis emerges out of her recognition that there is a contradiction between this way of conferring rights as tied to the nation-state system and the more philosophical and ethical conceptions of the ‘rights of man’ and notions of ‘human rights’ like those championed by thinkers such as Immanuel Kant who understands (...)

    Karl Pfeifer attempts to present a coherent view of panentheism that eschews Pickwickian senses of “in” and aligns itself with, and builds upon, familiar diagrammed portrayals of panentheism. The account is accordingly spatial-locative and moreover accepts the proposal of R.T. Mullins that absolute space and time be regarded as attributes of God. In addition, however, it argues that a substantive parthood relation between the world and God is required. Pfeifer’s preferred version of panpsychism, viz. panintentionalism, is thrown into (...)

    In this paper we exploit the notions of conjoined and iterated conditionals, which are defined in the setting of coherence by means of suitable conditional random quantities with values in the interval [0,1]. We examine the iterated conditional (B|K)|(A|H), by showing that A|H p-entails B|K if and only if (B|K)|(A|H) = 1. Then, we show that a p-consistent family F={E1|H1, E2|H2} p-entails a conditional event E3|H3 if and only if E3|H3= 1, or (E3|H3)|QC(S) = 1 for some nonempty subset S (...)

    Probabilistic interpretations of argumentative attacks: Logical and experimental results.Niki Pfeifer & Christian G. Fermüller - 2023 - Argument and Computation 14 (1):75-107.
    We present an interdisciplinary approach to argumentation combining logical, probabilistic, and psychological perspectives. We investigate logical attack principles which relate attacks among claims with logical form. For example, we consider the principle that an argument that attacks another argument claiming A triggers the existence of an attack on an argument featuring the stronger claim A ∧ B. We formulate a number of such principles pertaining to conjunctive, disjunctive, negated, and implicational claims. Some of these attack principles seem to be prima (...)
