Structure coefficients and strategy selection in multiplayer games.

Science.gov (United States)

McAvoy, Alex; Hauert, Christoph

2016-01-01

Evolutionary processes based on two-player games such as the Prisoner's Dilemma or Snowdrift Game are abundant in evolutionary game theory. These processes, including those based on games with more than two strategies, have been studied extensively under the assumption that selection is weak. However, games involving more than two players have not received the same level of attention. To address this issue, and to relate two-player games to multiplayer games, we introduce a notion of reducibility for multiplayer games that captures what it means to break down a multiplayer game into a sequence of interactions with fewer players. We discuss the role of reducibility in structured populations, and we give examples of games that are irreducible in any population structure. Since the known conditions for strategy selection, otherwise known as [Formula: see text]-rules, have been established only for two-player games with multiple strategies and for multiplayer games with two strategies, we extend these rules to multiplayer games with many strategies to account for irreducible games that cannot be reduced to those simpler types of games. In particular, we show that the number of structure coefficients required for a symmetric game with [Formula: see text]-player interactions and [Formula: see text] strategies grows in [Formula: see text] like [Formula: see text]. Our results also cover a type of ecologically asymmetric game based on payoff values that are derived not only from the strategies of the players, but also from their spatial positions within the population.

Virtue epistemologists hold that knowledge results from the display of epistemic virtues--open-mindedness, rigor, sensitivity to evidence, and the like. But epistemology cannot rest satisfied with a list of the virtues. What is wanted is a criterion for being an epistemic virtue. An extension of a formulation of Kant's categorical imperative…

In turn, this will make a case for the claim that we cannot use the standard possible worlds framework to model what is epistemically possible for ordinary agents....

Epistemic Authority and Genuine Ethical Controversies.

Science.gov (United States)

Roberts, Adam James

2017-05-01

In 'Professional Hubris and its Consequences', Eric Vogelstein claims that 'that there are no good arguments in favor of professional organizations taking genuinely controversial positions on issues of professional ethics'. In this response, I defend two arguments in favour of organisations taking such positions: that their stance-taking may lead to better public policy, and that it may lead to better practice by medical professionals. If either of those defences succeeds, then Vogelstein's easy path to his conclusion - that professional organisations should not take such stances - is blocked. He or others must instead look to establish that the reasons against stance-taking on genuine ethical controversies are more compelling than those for it: plausibly a more challenging task. © 2017 John Wiley & Sons Ltd.

Within the discussion and research on the nature of knowledge lies the highly debated issue of the relationship between ethics and scientific knowledge.

The epistemic innocence of psychedelic states.

Science.gov (United States)

Letheby, Chris

2016-01-01

One recent development in epistemology, the philosophical study of knowledge, is the notion of 'epistemic innocence' introduced by Bortolotti and colleagues. This concept expresses the idea that certain suboptimal cognitive processes may nonetheless have epistemic (knowledge-related) benefits. The idea that delusion or confabulation may have psychological benefits is familiar enough. What is novel and interesting is the idea that such conditions may also yield significant and otherwise unavailable epistemic benefits. I apply the notion of epistemic innocence to research on the transformative potential of psychedelic drugs. The popular epithet 'hallucinogen' exemplifies a view of these substances as fundamentally epistemically detrimental. I argue that the picture is more complicated and that some psychedelic states can be epistemically innocent. This conclusion is highly relevant to policy debates about psychedelic therapy. Moreover, analysing the case of psychedelics can shed further light on the concept of epistemic innocence itself. Copyright © 2015 Elsevier Inc. All rights reserved.

Bridging Parallel Rows: Epistemic Difference and Relational Accountability in Cross-Cultural Research

Full Text Available To what extent are non-Indigenous researchers invited to engage the knowledges of Indigenous peoples? For those working within a western paradigm, what is an ethical approach to traditional knowledge (TK research? While these questions are not openly addressed in the burgeoning literature on TK, scholarship on Indigenous research methodologies provides guidance. Reflexive self-study - what Margaret Kovach calls researcher preparation - subtends an ethical approach. It makes relational, contextual, and mutually beneficial research possible. In my work on contested fisheries knowledge and decision-making systems in Ontario, Canada, a treaty perspective orients my mixed methodological approach. It reflects my relationships to Indigenous lands, peoples, and histories, and enables an ethical space of engagement through which relational accountability and respect for epistemic difference can be realized.

The Historical Basis of Engineering Ethics

Science.gov (United States)

Furuya, Keiichi

There are different objects and motives between scientists and engineers. Science is to create new knowledge (episteme), while technology (techne) is to create new utility. Both types of social responsibility are required for engineer, because modern technology is tightly connected with science. The relationship between ethics for scientists and engineers is discussed as an evolution of ethical objects. A short history of engineering societies in U.S.A. and Japan are introduced with their ethical perspectives. As a conclusion, respect for fundamental rights for existence of those who stand in, with, and around engineers and their societies is needed for better engineering ethics.

Basing Science Ethics on Respect for Human Dignity.

Science.gov (United States)

Aközer, Mehmet; Aközer, Emel

2016-12-01

A "no ethics" principle has long been prevalent in science and has demotivated deliberation on scientific ethics. This paper argues the following: (1) An understanding of a scientific "ethos" based on actual "value preferences" and "value repugnances" prevalent in the scientific community permits and demands critical accounts of the "no ethics" principle in science. (2) The roots of this principle may be traced to a repugnance of human dignity, which was instilled at a historical breaking point in the interrelation between science and ethics. This breaking point involved granting science the exclusive mandate to pass judgment on the life worth living. (3) By contrast, respect for human dignity, in its Kantian definition as "the absolute inner worth of being human," should be adopted as the basis to ground science ethics. (4) The pathway from this foundation to the articulation of an ethical duty specific to scientific practice, i.e., respect for objective truth, is charted by Karl Popper's discussion of the ethical principles that form the basis of science. This also permits an integrated account of the "external" and "internal" ethical problems in science. (5) Principles of the respect for human dignity and the respect for objective truth are also safeguards of epistemic integrity. Plain defiance of human dignity by genetic determinism has compromised integrity of claims to knowledge in behavioral genetics and other behavioral sciences. Disregard of the ethical principles that form the basis of science threatens epistemic integrity.

Evidentiality, Epistemic Modality, and Epistemic Status

Directory of Open Access Journals (Sweden)

Rezeda Dilshatovna Shakirova

2016-09-01

Full Text Available The article discusses the interaction of evidentiality categories, typical of many Turkic, Finno-Ugric, Samoyed, certain Slavic, and other languages with the categories of epistemic modality, which is widely represented particularly in Germanic languages. The methodological framework of this study consists of the general philosophic, general scientific and private levels. The general philosophic methodology is based on the analytic philosophy, under the linguistic trend of which the language study was carried out to solve philosophic problems. The general scientific methodological bases of the study are related to the principle of identifying similarities and differences of the categories analyzed and the systematicity of description, whereas the descriptive method and techniques thereof are used primarily as the private-linguistic methods. In contrast to evidentiality, indicating the source of information, the epistemic modality marks different level of the information reliability. In the modern German language, the categories studied have a zone of intersection in terms of community within the means of expression, to which modal words and modal verbs as well as the verb scheinen can be primarily related. However, in the modern German language, there is no question of the category of evidentiality in the plane, within which it is currently being studied basing on the material of those languages, to the fragment of the grammatical system of which it is primarily inherent. As a rule, the semantics of evidentiality in these languages provides no information on the degree of reliability of the source of knowledge. To overcome the contradiction of such nature, this work suggests paying attention to the category of epistemic status of an utterance, the semantic structure of which is wider than evidentiality and epistemic modality and includes the level of reliability of the source of knowledge along with the designation thereof. In today's German

Extended Cognitive System and Epistemic Subject

Directory of Open Access Journals (Sweden)

Trybulec Barbara

2015-03-01

Full Text Available The concept of an extended cognitive system is central to contemporary studies of cognition. In the paper I analyze the place of the epistemic subject within the extended cognitive system. Is it extended as well? In answering this question I focus on the differences between the first and the second wave of arguments for the extended mind thesis. I argue that the position of Cognitive Integration represented by Richard Menary is much more intuitive and fruitful in analyses of cognition and knowledge than the early argument formulated by Andy Clark and David Chalmers. Cognitive Integration is compatible with virtue epistemology of John Greco’s agent reliabilism. The epistemic subject is constituted by its cognitive character composed of an integrated set of cognitive abilities and processes. Some of these processes are extended, they are a manipulation of external informational structures and, as such, they constitute epistemic practices. Epistemic practices are normative; to conduct them correctly the epistemic subject needs to obey epistemic norms embedded in the cultural context. The epistemic subject is not extended because of the casual coupling with external informational artifacts which extend his mind from inside the head and into the world. Rather, cognitive practices constitute the subject’s mind, they transform his cognitive abilities, and this is what makes the mind and epistemic subject “extended”.

Reliability analysis under epistemic uncertainty

International Nuclear Information System (INIS)

Nannapaneni, Saideep; Mahadevan, Sankaran

2016-01-01

This paper proposes a probabilistic framework to include both aleatory and epistemic uncertainty within model-based reliability estimation of engineering systems for individual limit states. Epistemic uncertainty is considered due to both data and model sources. Sparse point and/or interval data regarding the input random variables leads to uncertainty regarding their distribution types, distribution parameters, and correlations; this statistical uncertainty is included in the reliability analysis through a combination of likelihood-based representation, Bayesian hypothesis testing, and Bayesian model averaging techniques. Model errors, which include numerical solution errors and model form errors, are quantified through Gaussian process models and included in the reliability analysis. The probability integral transform is used to develop an auxiliary variable approach that facilitates a single-level representation of both aleatory and epistemic uncertainty. This strategy results in an efficient single-loop implementation of Monte Carlo simulation (MCS) and FORM/SORM techniques for reliability estimation under both aleatory and epistemic uncertainty. Two engineering examples are used to demonstrate the proposed methodology. - Highlights: • Epistemic uncertainty due to data and model included in reliability analysis. • A novel FORM-based approach proposed to include aleatory and epistemic uncertainty. • A single-loop Monte Carlo approach proposed to include both types of uncertainties. • Two engineering examples used for illustration.

The epistemic culture in an online citizen science project: Programs, antiprograms and epistemic subjects.

Science.gov (United States)

Kasperowski, Dick; Hillman, Thomas

2018-05-01

In the past decade, some areas of science have begun turning to masses of online volunteers through open calls for generating and classifying very large sets of data. The purpose of this study is to investigate the epistemic culture of a large-scale online citizen science project, the Galaxy Zoo, that turns to volunteers for the classification of images of galaxies. For this task, we chose to apply the concepts of programs and antiprograms to examine the 'essential tensions' that arise in relation to the mobilizing values of a citizen science project and the epistemic subjects and cultures that are enacted by its volunteers. Our premise is that these tensions reveal central features of the epistemic subjects and distributed cognition of epistemic cultures in these large-scale citizen science projects.

A Quantum Computational Semantics for Epistemic Logical Operators. Part I: Epistemic Structures

Science.gov (United States)

Beltrametti, Enrico; Dalla Chiara, Maria Luisa; Giuntini, Roberto; Leporini, Roberto; Sergioli, Giuseppe

2014-10-01

Some critical open problems of epistemic logics can be investigated in the framework of a quantum computational approach. The basic idea is to interpret sentences like "Alice knows that Bob does not understand that π is irrational" as pieces of quantum information (generally represented by density operators of convenient Hilbert spaces). Logical epistemic operators ( to understand, to know…) are dealt with as (generally irreversible) quantum operations, which are, in a sense, similar to measurement-procedures. This approach permits us to model some characteristic epistemic processes, that concern both human and artificial intelligence. For instance, the operation of "memorizing and retrieving information" can be formally represented, in this framework, by using a quantum teleportation phenomenon.

Automata Techniques for Epistemic Protocol Synthesis

Directory of Open Access Journals (Sweden)

Guillaume Aucher

2014-04-01

Full Text Available In this work we aim at applying automata techniques to problems studied in Dynamic Epistemic Logic, such as epistemic planning. To do so, we first remark that repeatedly executing ad infinitum a propositional event model from an initial epistemic model yields a relational structure that can be finitely represented with automata. This correspondence, together with recent results on uniform strategies, allows us to give an alternative decidability proof of the epistemic planning problem for propositional events, with as by-products accurate upper-bounds on its time complexity, and the possibility to synthesize a finite word automaton that describes the set of all solution plans. In fact, using automata techniques enables us to solve a much more general problem, that we introduce and call epistemic protocol synthesis.

Coupled Ethical-Epistemic Analysis of Climate Change

Science.gov (United States)

Vezer, M.

2015-12-01

Are there inherent limitations to what we can know about how the climate will change in the years ahead? How can we use what is known about the future climate in a way that promotes ethical decision-making? These questions call for urgent attention because important policy decisions need to be made in order to prepare for climate change in North America and around the world. While the science of climate change is central to this line of inquiry, the fields of epistemology, moral, political and environmental philosophy may provide insights on how these issues should be addressed. Detailing the relationship between evidential and ethical dimensions of climate change, this research aims to improve our understanding of the interconnections among several lines of inquiry and to develop solutions to problems of decision-making under conditions of scientific uncertainty.

A gentle ethical defence of homeopathy.

Science.gov (United States)

Levy, David; Gadd, Ben; Kerridge, Ian; Komesaroff, Paul A

2015-06-01

Recent discourses about the legitimacy of homeopathy have focused on its scientific plausibility, mechanism of action, and evidence base. These, frequently, conclude not only that homeopathy is scientifically baseless, but that it is "unethical." They have also diminished patients' perspectives, values, and preferences. We contend that these critics confuse epistemic questions with questions of ethics, misconstrue the moral status of homeopaths, and have an impoverished idea of ethics-one that fails to account either for the moral worth of care and of relationships or for the perspectives, values, and preferences of patients. Utilitarian critics, in particular, endeavour to present an objective evaluation-a type of moral calculus-quantifying the utilities and disutilities of homeopathy as a justification for the exclusion of homeopathy from research and health care. But these critiques are built upon a narrow formulation of evidence and care and a diminished episteme that excludes the values and preferences of researchers, homeopaths, and patients engaged in the practice of homeopathy. We suggest that homeopathy is ethical as it fulfils the needs and expectations of many patients; may be practiced safely and prudentially; values care and the virtues of the therapeutic relationship; and provides important benefits for patients.

Confronting diminished epistemic privilege and epistemic injustice in pregnancy by challenging a "panoptics of the womb".

Science.gov (United States)

Freeman, Lauren

2015-02-01

This paper demonstrates how the problematic kinds of epistemic power that physicians have can diminish the epistemic privilege that pregnant women have over their bodies and can put them in a state of epistemic powerlessness. This result, I argue, constitutes an epistemic injustice for many pregnant women. A reconsideration of how we understand and care for pregnant women and of the physician-patient relationship can provide us with a valuable context and starting point for helping to alleviate the knowledge/power problems that are symptomatic of the current system and structure of medicine. I suggest that we can begin to confront this kind of injustice if medicine adopts a more phenomenological understanding of bodies and if physicians and patients--in this case, pregnant women--become what I call "epistemic peers." © The Author 2014.

2012-08-01

Active videogames (AVGs) have potential in terms of physical activity and therapy for children with cerebral palsy. However, the effect of social interaction on AVG play has not yet been assessed. The objective of this study is to determine if multiplayer AVG versus solo affects levels of energy expenditure and movement patterns. Fifteen children (9.77 [standard deviation (SD) 1.78] years old) with hemiplegic cerebral palsy (Gross Motor Function Classification System Level I) participated in solo and multiplayer Nintendo(®) "Wii™ Boxing" (Nintendo, Inc., Redmond, WA) AVG play while energy expenditure and punching frequency were monitored. Moderate levels of physical activity were achieved with no significant differences in energy measures during multiplayer and solo play. Dominant arm punching frequency increased during the multiplayer session from 95.75 (SD 37.93) punches/minute to 107.77 (SD 36.99) punches/minute. Conversely, hemiplegic arm punching frequency decreased from 39.05 (SD 29.57) punches/minutes to 30.73 (SD 24.74) punches/minutes during multiplayer game play. Children enjoyed multiplayer more than solo play. Opportunities to play AVGs with friends and family may translate to more frequent participation in this moderate physical activity. Conversely, increased hemiplegic limb use during solo play may have therapeutic advantages. As such, new strategies are recommended to promote use of the hemiplegic hand during multiplayer AVG play and to optimize commercial AVG systems for applications in virtual reality therapy.

Confabulation and epistemic authority.

2018-01-01

Mahr & Csibra (M&C) claim that episodic remembering's autonoetic character serves as an indicator of epistemic authority. This proposal is difficult to reconcile with the existence of confabulation errors - where participants fabricate memories of experiences that never happened to them. Making confabulation errors damages one's epistemic authority, but these false memories have an autonoetic character.

Physiological Responses During Multiplay Exergaming in Young Adult Males are Game-Dependent

McGuire Stephen

2015-06-01

Full Text Available Regular moderate-intensity exercise provides health benefits. The aim of this study was to examine whether the selected exercise intensity and physiological responses during exergaming in a single and multiplayer mode in the same physical space were game-dependent. Ten males (mean ±SD, age: 23 ±5 years, body mass: 84.2 ±15.6 kg, body height: 180 ±7 cm, body mass index: 26.0 ±4.0 kg·m−2 played the games Kinect football, boxing and track & field (3 × ~10 min, ~ 2 min rest periods in similar time sequence in two sessions. Physiological responses were measured with the portable Cosmed K4b2 pulmonary gas exchange system. Single play demands were used to match with a competitive opponent in a multiplay mode. A within-subjects crossover design was used with one-way ANOVA and a post-hoc t-test for analysis (p<0.05. Minute ventilation, oxygen uptake and the heart rate were at least 18% higher during a multiplayer mode for Kinect football and boxing but not for track & field. Energy expenditure was 21% higher during multiplay football. Single play track & field had higher metabolic equivalent than single play football (5.7 ±1.6, range: 3.2-8.6 vs 4.1 ±1.0, range: 3.0-6.1, p<0.05. Exergaming in a multiplayer mode can provide higher physiological demands but the effects are game-dependent. It seems that exergaming with low intensity in a multiplayer mode may provide a greater physical challenge for participants than in a single play mode but may not consistently provide sufficient intensity to acquire health benefits when played regularly as part of a programme to promote and maintain health in young adults.

Inevitability, contingency, and epistemic humility.

Science.gov (United States)

Kidd, Ian James

2016-02-01

This paper offers an epistemological framework for the debate about whether the results of scientific enquiry are inevitable or contingent. I argue in Sections 2 and 3 that inevitabilist stances are doubly guilty of epistemic hubris--a lack of epistemic humility--and that the real question concerns the scope and strength of our contingentism. The latter stages of the paper-Sections 4 and 5-address some epistemological and historiographical worries and sketch some examples of deep contingencies to guide further debate. I conclude by affirming that the concept of epistemic humility can usefully inform critical reflection on the contingency of the sciences and the practice of history of science.

Neuroscience and Ethics.

Science.gov (United States)

Liao, S Matthew

2017-03-01

A number of people believe that results from neuroscience have the potential to settle seemingly intractable debates concerning the nature, practice, and reliability of moral judgments. In particular, Joshua Greene has argued that evidence from neuroscience can be used to advance the long-standing debate between consequentialism and deontology. This paper first argues that charitably interpreted, Greene's neuroscientific evidence can contribute to substantive ethical discussions by being part of an epistemic debunking argument. It then argues that taken as an epistemic debunking argument, Greene's argument falls short in undermining deontological judgments. Lastly, it proposes that accepting Greene's methodology at face value, neuroimaging results may in fact call into question the reliability of consequentialist judgments. The upshot is that Greene's empirical results do not undermine deontology and that Greene's project points toward a way by which empirical evidence such as neuroscientific evidence can play a role in normative debates.

2005-01-01

Charge transfer multiplayer films have been prepared by layer-by-layer self-assembly technique. The films incorporate the rare-earth-containing polyoxometalate K 11 [Eu{PW 11 O 39 } 2 ].nH 2 O and the rich electron polyelectrolyte poly(3-viny-1-methyl-pyridine) quaternary ammonium and display a linear increase in the absorption and film thickness with the number of deposition cycles. Ultraviolet and visible absorption spectra, atomic force micrographs, small-angle X-ray reflectivity measurements, and photoluminescence spectra were used to determine the structure of films. Linear and regular multilayer growth was observed. We can observe the formation of charge transfer complex compound in multiplayer by layer-by-layer assembly method. Most importantly, the luminescence spectra show the charge transfer band in assembly films, which suggest that energy could be effectively transferred to rare earth ions in assembly multiplayer films

Representation of analysis results involving aleatory and epistemic uncertainty.

Energy Technology Data Exchange (ETDEWEB)

Johnson, Jay Dean (ProStat, Mesa, AZ); Helton, Jon Craig (Arizona State University, Tempe, AZ); Oberkampf, William Louis; Sallaberry, Cedric J.

Procedures are described for the representation of results in analyses that involve both aleatory uncertainty and epistemic uncertainty, with aleatory uncertainty deriving from an inherent randomness in the behavior of the system under study and epistemic uncertainty deriving from a lack of knowledge about the appropriate values to use for quantities that are assumed to have fixed but poorly known values in the context of a specific study. Aleatory uncertainty is usually represented with probability and leads to cumulative distribution functions (CDFs) or complementary cumulative distribution functions (CCDFs) for analysis results of interest. Several mathematical structures are available for the representation of epistemic uncertainty, including interval analysis, possibility theory, evidence theory and probability theory. In the presence of epistemic uncertainty, there is not a single CDF or CCDF for a given analysis result. Rather, there is a family of CDFs and a corresponding family of CCDFs that derive from epistemic uncertainty and have an uncertainty structure that derives from the particular uncertainty structure (i.e., interval analysis, possibility theory, evidence theory, probability theory) used to represent epistemic uncertainty. Graphical formats for the representation of epistemic uncertainty in families of CDFs and CCDFs are investigated and presented for the indicated characterizations of epistemic uncertainty.

Aristotle on Deliberation:Its Place in Ethics, Politics and Rhetoric

OpenAIRE

Kock, Christian Erik J

2014-01-01

Aristotle differs from most later philosophers in distinguishing clearly between epistemic reasoning, which aims for truth, and practical reasoning, which does not. How can he posit this distinction and yet not dismiss practical reasoning as flattery and manipulation, as Plato did? The answer lies in the concepts of deliberation (boulē, bouleusis) and deliberate choice (proairesis). They link Aristotle's rhetoric, ethics, and politics together and help provide definitions of all three: Ethics...

Fuzzy Versions of Epistemic and Deontic Logic

Science.gov (United States)

Gounder, Ramasamy S.; Esterline, Albert C.

1998-01-01

Epistemic and deontic logics are modal logics, respectively, of knowledge and of the normative concepts of obligation, permission, and prohibition. Epistemic logic is useful in formalizing systems of communicating processes and knowledge and belief in AI (Artificial Intelligence). Deontic logic is useful in computer science wherever we must distinguish between actual and ideal behavior, as in fault tolerance and database integrity constraints. We here discuss fuzzy versions of these logics. In the crisp versions, various axioms correspond to various properties of the structures used in defining the semantics of the logics. Thus, any axiomatic theory will be characterized not only by its axioms but also by the set of properties holding of the corresponding semantic structures. Fuzzy logic does not proceed with axiomatic systems, but fuzzy versions of the semantic properties exist and can be shown to correspond to some of the axioms for the crisp systems in special ways that support dependency networks among assertions in a modal domain. This in turn allows one to implement truth maintenance systems. For the technical development of epistemic logic, and for that of deontic logic. To our knowledge, we are the first to address fuzzy epistemic and fuzzy deontic logic explicitly and to consider the different systems and semantic properties available. We give the syntax and semantics of epistemic logic and discuss the correspondence between axioms of epistemic logic and properties of semantic structures. The same topics are covered for deontic logic. Fuzzy epistemic and fuzzy deontic logic discusses the relationship between axioms and semantic properties for these logics. Our results can be exploited in truth maintenance systems.

Spontaneous Cognition and Epistemic Agency in the Cognitive Niche

Science.gov (United States)

Fabry, Regina E.

2018-01-01

According to Thomas Metzinger, many human cognitive processes in the waking state are spontaneous and are deprived of the experience of epistemic agency. He considers mind wandering as a paradigm example of our recurring loss of epistemic agency. I will enrich this view by extending the scope of the concept of epistemic agency to include cases of depressive rumination and creative cognition, which are additional types of spontaneous cognition. Like mind wandering, they are characterized by unique phenomenal and functional properties that give rise to varying degrees of epistemic agency. The main claim of this paper will be that the experience of being an epistemic agent within a certain time frame is a relational phenomenon that emerges from the organism’s capacity to interact with its cognitive niche. To explore this relation, I develop a new framework that integrates phenomenological considerations on epistemic agency with a functional account of the reciprocal coupling of the embodied organism with its cognitive niche. This account rests upon dynamical accounts of strong embodied and embedded cognition and recent work on cognitive niche construction. Importantly, epistemic agency and organism-niche coupling are gradual phenomena ranging from weak to strong realizations. The emerging framework will be employed to analyze mind wandering, depressive rumination, and creative cognition as well as their commonalities and differences. Mind wandering and depressive rumination are cases of weak epistemic agency and organism-niche coupling. However, there are also important phenomenological, functional, and neuronal differences. In contrast, creative cognition is a case of strong epistemic agency and organism-niche coupling. By providing a phenomenological and functional analysis of these distinct types of spontaneous cognition, we can gain a better understanding of the importance of organism-niche interaction for the realization of epistemic agency.

Ethics and epistemology of accurate prediction in clinical research.

Science.gov (United States)

Hey, Spencer Phillips

2015-07-01

All major research ethics policies assert that the ethical review of clinical trial protocols should include a systematic assessment of risks and benefits. But despite this policy, protocols do not typically contain explicit probability statements about the likely risks or benefits involved in the proposed research. In this essay, I articulate a range of ethical and epistemic advantages that explicit forecasting would offer to the health research enterprise. I then consider how some particular confidence levels may come into conflict with the principles of ethical research. Published by the BMJ Publishing Group Limited.

Risk informed decision-making and its ethical basis

International Nuclear Information System (INIS)

Ersdal, Gerhard; Aven, Terje

2008-01-01

In decision-making under uncertainty there are two main questions that need to be evaluated: (i) What are the future consequences and associated uncertainties of an action, and (ii) what is a good (or right) decision or action. Philosophically these issues are categorized as epistemic questions (i.e. questions of knowledge) and ethical questions (i.e. questions of moral and norms). This paper discusses the second issue, and evaluates different risk management approaches for establishing good decisions, using different ethical theories as a basis. These theories include the utilitarian ethics of Bentley and Mills, and deontological ethics of Kant, Rawls and Habermas. The risk management approaches include cost-benefit analysis (CBA), minimum safety criterion, the ALARP principle and the precautionary principle

The Limits of Epistemic Communities: EU Security Agencies

Directory of Open Access Journals (Sweden)

Mai'a K. Davis Cross

2015-03-01

Full Text Available This article examines the cases of the European Defence Agency (EDA and EU Intelligence Analysis Centre (IntCen to argue that although they are comprised of high-level security experts, they do not constitute epistemic communities. Research on other groups of security experts based in Brussels has shown that epistemic communities of diplomats, military experts, security researchers, and civilian crisis management experts, among others, have been able to influence the trajectory of security integration by virtue of their shared knowledge. Importantly, these security epistemic communities have been shown to significantly impact outcomes of EU security policy beyond what would be expected by looking only at member-states’ initial preferences. In exploring two examples of “non-cases” that are at the same time very similar to the other examples, the author seeks to shed light on why some expert groups do not form epistemic communities, and how this changes the nature of their influence. In so doing, the goal is to sharpen the parameters of what constitutes epistemic communities, and to add to our understanding of why they emerge. The argument advanced in this article is that institutional context and the nature of the profession matter as preconditions for epistemic community emergence.

Shared vs. Primary Epistemic Authority in Jaminjung/Ngaliwurru

Directory of Open Access Journals (Sweden)

Schultze-Berndt Eva

2017-10-01

Full Text Available This paper contributes to the typology of complex perspective markers by presenting an in-depth analysis of a system of epistemic authority marking which functionally overlaps with, but has no exact parallels in, similar systems attested cross-linguistically; it is also the first analysis of grammaticalised marking of epistemic authority in a language of Australia. Jaminjung/Ngaliwurru, a language of the Mirndi family, distinguishes between primary and shared epistemic authority by means of two non-obligatory clitics. By employing the first clitic, speakers claim privileged (asymmetrical access to evidence informing their utterance; the holder of epistemic primacy shifts to addressees in questions. The second marker, which is transparently related to a 1st+2nd person minimal pronoun, indicates shared (symmetrical epistemic access, but is further constrained in its distribution in that the evidence has to be accessible at the time of discourse and in that the encoded situation itself is not yet part of the common ground. In the light of the proposed analysis as well as cross-linguistic findings, it will be argued that epistemic authority markers more generally can be considered as part of a single functional domain with evidentials, and that this domain also includes egophoricity.

Natura relacji epistemicznej (The nature of epistemic relation

Directory of Open Access Journals (Sweden)

Stanisław Judycki

2012-03-01

Full Text Available The article begins with the question concerning the relation between the so called definition of knowledge (E. Gettier and the epistemic relation but its main part aims at showing what are the most important constituents of this relation (constituents of the idea of knowledge in general. Fundamental for the possibility of epistemic relation is the presence of some kind of conscious subject. In this context critical remarks are considered concerning contemporary naturalistic approaches to the idea of knowledge where the possibility of wholly unconscious cognition (knowledge has been seriously taken into account (e.g. robots capable of adaptive behavior in some environment. The second essential element of epistemic relation is the existence of some object (content, which conscious subject must be capable to grasp. The extent of the concept of object (content cannot be limited to the realm of physical things because epistemic relation also allows for the presence of abstract objects. It also allows for the presence of objects wholly unknown to human cognizing subjects. On the one hand, taken as such, epistemic relation does not possess any causal character, but on the other hand it can be based on some causal relation. It can also ‘assimilate’ other than physical kinds of conditioning, e.g. exemplifi cation of properties understood in a platonic sense. As a necessary constituent of each kind of epistemic relation must be treated the element of representation and here it stressed the importance of the distinction between subject of epistemic relation on the one hand and the ‘mind’ that this subject ‘possesses’, ‘mind’ interpreted as a system of representations. To the necessary elements of each epistemic relation belongs the activity of categorization but this categorization does to have to be ofsemantic character and it must not contain two fundamental forms of human intuition, i.e. space and time. Other forms of intuition, wholly

Epistemic Information in Stratified M-Spaces

Directory of Open Access Journals (Sweden)

Mark Burgin

2011-12-01

Full Text Available Information is usually related to knowledge. However, the recent development of information theory demonstrated that information is a much broader concept, being actually present in and virtually related to everything. As a result, many unknown types and kinds of information have been discovered. Nevertheless, information that acts on knowledge, bringing new and updating existing knowledge, is of primary importance to people. It is called epistemic information, which is studied in this paper based on the general theory of information and further developing its mathematical stratum. As a synthetic approach, which reveals the essence of information, organizing and encompassing all main directions in information theory, the general theory of information provides efficient means for such a study. Different types of information dynamics representation use tools of mathematical disciplines such as the theory of categories, functional analysis, mathematical logic and algebra. Here we employ algebraic structures for exploration of information and knowledge dynamics. In Introduction (Section 1, we discuss previous studies of epistemic information. Section 2 gives a compressed description of the parametric phenomenological definition of information in the general theory of information. In Section 3, anthropic information, which is received, exchanged, processed and used by people is singled out and studied based on the Componential Triune Brain model. One of the basic forms of anthropic information called epistemic information, which is related to knowledge, is analyzed in Section 4. Mathematical models of epistemic information are studied in Section 5. In Conclusion, some open problems related to epistemic information are given.

A case study of epistemic order in mathematics classroom dialogue

Kenneth Ruthven

2016-09-01

Full Text Available We define epistemic order as the way in which the exchange and development of knowledge takes place in the classroom, breaking this down into a system of three components: epistemic initiative relating to who sets the agenda in classroom dialogue, and how; epistemic appraisal relating to who judges contributions to classroom dialogue, and how; and epistemic framing relating to the terms in which development and exchange of knowledge are represented, particularly in reflexive talk. These components are operationalised in terms of various types of structural and semantic analysis of dialogue. It is shown that a lesson segment displays a multi-layered epistemic order differing from that of conventional classroom recitation.

The Epistemic Standards of Public Reason*

Directory of Open Access Journals (Sweden)

Tutui Viorel

2011-01-01

Full Text Available Abstract: Many contemporary philosophers have adopted the deliberative theory of democracy, according to which, a political decision is legitimate if it was established by a deliberative procedure. In this article I argue that the important objections which affect proceduralist and epistemic versions of this theory can be overcome if we carefully distinguish the epistemic and the political dimensions of democratic deliberation, instead of trying to derive one from the other. Moreover, we have to understand how does the deliberative process itself contribute to the legitimacy of the political decision and what is the role of the standards and conditions that are justified independently of the procedure. Using this distinction I will try to demonstrate that the deliberation itself is insufficient to secure the epistemic correctness and the political legitimacy of political decisions

Experts, meta-expertise and mediators. Ethical oversight of research in multidisciplinary scenarios

Directory of Open Access Journals (Sweden)

Wilfredo Betancourt Mosquera

2016-07-01

Full Text Available Based on a case study drawn from the written records of a Colombian Research Ethics Committee (rec, this article discusses the impact that its multidisciplinary nature has on its decision-making processes. recs are analyzed as “boundary organizations” in which experts from different disciplines can meet. Additionally, recs are viewed as contemporary socio-epistemic arenas in which research ethics are produced. It was found that multiple expertise is often seen by some of its members as an «anomaly» which impedes ordinary work and ideally should be avoided. During the assessment of research projects the rec sought to manage this task through homogenizing decision-making processes in accordance with the expertise of some of its members, avoiding the convergence of «communities of practice.» Furthermore, the members of the rec frequently base their decisions either on their own ethical judgments, or by mirroring those of more qualified reviewers. This dynamic is largely a consequence of «meta-expertise,» that is to say, rec members’ ability or legitimacy to judge expert knowledge which they do not possess. It is concluded that researchers have wide possibilities to interpret and define the ethical dimension of their work. Within local practices of ethical reviews, researchers act as «interactional» actors able to assess and communicate recs about their own ethics. Paradoxically, despite their character as a public setting for multidisciplinary dialogue, recs end up being spaces in which the professional esotericism of disciplinary communities is reaffirmed and the socio-epistemic authority of experts reinforced.

The Ethics of Cloud Computing.

de Bruin, Boudewijn; Floridi, Luciano

2017-02-01

Cloud computing is rapidly gaining traction in business. It offers businesses online services on demand (such as Gmail, iCloud and Salesforce) and allows them to cut costs on hardware and IT support. This is the first paper in business ethics dealing with this new technology. It analyzes the informational duties of hosting companies that own and operate cloud computing datacentres (e.g., Amazon). It considers the cloud services providers leasing 'space in the cloud' from hosting companies (e.g., Dropbox, Salesforce). And it examines the business and private 'clouders' using these services. The first part of the paper argues that hosting companies, services providers and clouders have mutual informational (epistemic) obligations to provide and seek information about relevant issues such as consumer privacy, reliability of services, data mining and data ownership. The concept of interlucency is developed as an epistemic virtue governing ethically effective communication. The second part considers potential forms of government restrictions on or proscriptions against the development and use of cloud computing technology. Referring to the concept of technology neutrality, it argues that interference with hosting companies and cloud services providers is hardly ever necessary or justified. It is argued, too, however, that businesses using cloud services (e.g., banks, law firms, hospitals etc. storing client data in the cloud) will have to follow rather more stringent regulations.

Characterizing Epistemic Uncertainty for Launch Vehicle Designs

Science.gov (United States)

Novack, Steven D.; Rogers, Jim; Hark, Frank; Al Hassan, Mohammad

2016-01-01

NASA Probabilistic Risk Assessment (PRA) has the task of estimating the aleatory (randomness) and epistemic (lack of knowledge) uncertainty of launch vehicle loss of mission and crew risk and communicating the results. Launch vehicles are complex engineered systems designed with sophisticated subsystems that are built to work together to accomplish mission success. Some of these systems or subsystems are in the form of heritage equipment, while some have never been previously launched. For these cases, characterizing the epistemic uncertainty is of foremost importance, and it is anticipated that the epistemic uncertainty of a modified launch vehicle design versus a design of well understood heritage equipment would be greater. For reasons that will be discussed, standard uncertainty propagation methods using Monte Carlo simulation produce counter intuitive results and significantly underestimate epistemic uncertainty for launch vehicle models. Furthermore, standard PRA methods such as Uncertainty-Importance analyses used to identify components that are significant contributors to uncertainty are rendered obsolete since sensitivity to uncertainty changes are not reflected in propagation of uncertainty using Monte Carlo methods.This paper provides a basis of the uncertainty underestimation for complex systems and especially, due to nuances of launch vehicle logic, for launch vehicles. It then suggests several alternative methods for estimating uncertainty and provides examples of estimation results. Lastly, the paper shows how to implement an Uncertainty-Importance analysis using one alternative approach, describes the results, and suggests ways to reduce epistemic uncertainty by focusing on additional data or testing of selected components.

Embedding epistemic modals in English: A corpus-based study

2012-07-01

Full Text Available The question of whether epistemic modals contribute to the truth conditions of the sentences they appear in is a matter of active debate in the literature. Fueling this debate is the lack of consensus about the extent to which epistemics can appear in the scope of other operators. This corpus study investigates the distribution of epistemics in naturalistic data. Our results indicate that they do embed, supporting the view that they contribute semantic content. However, their distribution is limited, compared to that of other modals. This limited distribution seems to call for a nuanced account: while epistemics are semantically contentful, they may require special licensing conditions. http://dx.doi.org/10.3765/sp.5.4 BibTeX info

EPISTEMIC COMMUNITIES AND SERVICE DELIVERY CHOICES IN SPANISH MUNICIPAL ADMINISTRATIONS

Directory of Open Access Journals (Sweden)

Miquel SALVADOR

2015-12-01

Full Text Available This article contributes to the debate on the use of alternative formulas for public service provision with arguments related to epistemic communities’ influence. Drawing on the literature on models of local public service delivery, the role of internal epistemic communities is discussed and tested through the consideration of two different communities related to specific municipal areas such as personal and urban services. The results demonstrate that the association of urban services’ epistemic communities with alternative formulas for direct provision to deliver services is greater than in the case of personal services’ epistemic community. Those findings contribute to the academic debate not only with arguments and evidence that reinforces the role of variables included in previous research but also by introducing the role of epistemic communities in determining some policy options (as the use of local public-service delivery formulas.

Quantification of margins and uncertainties: Alternative representations of epistemic uncertainty

International Nuclear Information System (INIS)

Helton, Jon C.; Johnson, Jay D.

2011-01-01

In 2001, the National Nuclear Security Administration of the U.S. Department of Energy in conjunction with the national security laboratories (i.e., Los Alamos National Laboratory, Lawrence Livermore National Laboratory and Sandia National Laboratories) initiated development of a process designated Quantification of Margins and Uncertainties (QMU) for the use of risk assessment methodologies in the certification of the reliability and safety of the nation's nuclear weapons stockpile. A previous presentation, 'Quantification of Margins and Uncertainties: Conceptual and Computational Basis,' describes the basic ideas that underlie QMU and illustrates these ideas with two notional examples that employ probability for the representation of aleatory and epistemic uncertainty. The current presentation introduces and illustrates the use of interval analysis, possibility theory and evidence theory as alternatives to the use of probability theory for the representation of epistemic uncertainty in QMU-type analyses. The following topics are considered: the mathematical structure of alternative representations of uncertainty, alternative representations of epistemic uncertainty in QMU analyses involving only epistemic uncertainty, and alternative representations of epistemic uncertainty in QMU analyses involving a separation of aleatory and epistemic uncertainty. Analyses involving interval analysis, possibility theory and evidence theory are illustrated with the same two notional examples used in the presentation indicated above to illustrate the use of probability to represent aleatory and epistemic uncertainty in QMU analyses.

Power, Knowledge, and Epistemic Delinking

Directory of Open Access Journals (Sweden)

Aneta Stojnić

2017-10-01

Full Text Available In this paper I shall argue that radical epistemic delinking has a key role in liberation from the Colonial Matrix of Power as well as the change in the existing global power relations which are based in the colonialism and maintained through exploitation, expropriation and construction of the (racial Other. Those power relations render certain bodies and spaces as (epistemologically irrelevant. In order to discuss possible models of struggle against such condition, firstly I have addressed the relation between de-colonial theories and postcolonial studies, arguing that decolonial positions are both historicising and re-politicising the postcolonial theory. In my central argument I have focused on the epistemic delinking and political implications of decolonial turn. With reference to Grada Killomba I have argued for the struggle against epistemic violence through decolonising knowledge. Decolonising knowledge requires delinking form Eurocentric model of knowledge production and radical dismantling the existing hierarchies among different knowledge.

Epistemic Communities, Situated Learning and Open Source Software Development

DEFF Research Database (Denmark)

Edwards, Kasper

2001-01-01

This paper analyses open source software (OSS) development as an epistemic community where each individual project is perceived as a single epistemic community. OSS development is a learning process where the involved parties contribute to, and learn from the community. It is discovered that theory...... of epistemic communities does indeed contribute to the understanding of open source software development. But, the important learning process of open source software development is not readily explained. The paper then introduces situated learning and legitimate peripheral participation as theoretical...

at a price. The planning framework is undecidable, even if we allow only purely epistemic actions (actions that change only beliefs, not ontic facts). Undecidability holds already in the S5 setting with at least 2 agents, and even with 1 agent in S4. It shows that multi-agent planning is robustly undecidable......Dynamic epistemic logic (DEL) provides a very expressive framework for multi-agent planning that can deal with nondeterminism, partial observability, sensing actions, and arbitrary nesting of beliefs about other agents’ beliefs. However, as we show in this paper, this expressiveness comes...... if we assume that agents can reason with an arbitrary nesting of beliefs about beliefs. We also prove a corollary showing undecidability of the DEL model checking problem with the star operator on actions (iteration)....

Mapping university students’ epistemic framing of computational physics using network analysis

Directory of Open Access Journals (Sweden)

Madelen Bodin

2012-04-01

Full Text Available Solving physics problem in university physics education using a computational approach requires knowledge and skills in several domains, for example, physics, mathematics, programming, and modeling. These competences are in turn related to students’ beliefs about the domains as well as about learning. These knowledge and beliefs components are referred to here as epistemic elements, which together represent the students’ epistemic framing of the situation. The purpose of this study was to investigate university physics students’ epistemic framing when solving and visualizing a physics problem using a particle-spring model system. Students’ epistemic framings are analyzed before and after the task using a network analysis approach on interview transcripts, producing visual representations as epistemic networks. The results show that students change their epistemic framing from a modeling task, with expectancies about learning programming, to a physics task, in which they are challenged to use physics principles and conservation laws in order to troubleshoot and understand their simulations. This implies that the task, even though it is not introducing any new physics, helps the students to develop a more coherent view of the importance of using physics principles in problem solving. The network analysis method used in this study is shown to give intelligible representations of the students’ epistemic framing and is proposed as a useful method of analysis of textual data.

Ethics Committee or Community? Examining the identity of Czech Ethics Committees in the period of transition.

Simek, Jiri; Zamykalova, Lenka; Mesanyova, Marie

2010-09-01

Reflecting on a three year long exploratory research of ethics committees in the Czech Republic authors discuss the current role and identity of research ethics committees. The research of Czech ethics committees focused on both self-presentation and self-understanding of ECs members, and how other stakeholders (representatives of the pharmaceutical industry) view them. The exploratory research was based on formal and informal communication with the members of the ethics committees. Members of the research team took part at six regular voluntary meetings of the ethics committees' members, organised by the Forum of Czech Ethics Committees, and at three summer schools of medical ethics. There were realised twenty-five semi-structured interviews as well as six focus group sessions and a participant observation of several regular meetings of three ethics committees. On the grounds of experience from the interviews a simple questionnaire survey was realised among the members of the ethics committees. The ethics committees comprise a community of members working voluntarily, without claims to remuneration or prestige; the unifying goal is protection of subjects of research. The principal working methods are dialogue and agreement. The members of the ethics committees thus, among other things, create an informal community, which can be to a certain extent seen as a Kantian ethical community in a weak sense. The phenomenon of ethics committees can also be described by terms of an epistemic community and a community of practice. These concepts, which are borrowed from other authors and areas, are used as a way how to think of ECs role and identity a bit differently and are meant as a contribution to the current international debate on the topic.

A Study of the Relevance of Gender Identity and Characterization of Female Gamers in Massively Multiplayer Online Games

Directory of Open Access Journals (Sweden)

Mei-Hsueh Yang

2018-01-01

Full Text Available The population of female gamers of Massive Multiplayer Online Games has increased significantly. Massive Multiplayer Online Games provide a virtual stage for players to freely shape their virtual roles and rebuild their self-identification based on preferences. Thus, characterization has become one of the most important parts when discussing female gamers of Massive Multiplayer Online Games. To understand the relevance of gender identity and characterization of female gamers in Massive Multiplayer Online Games, this paper divides gender identity into two parts: sexual orientation and gender role; and separates characterization into three parts: gender, class, and appearance. The results show the following. In gender identity, most female gamers are attracted to men. In gender role, female gamers must gradually shed gender stereotypes. This paper also finds that female gamers turn gender stereotypes upside down concerning toys, jobs, housework, and leadership. In characterization, female gamers tend to create female roles, tend to choose wizard and archer as an occupation; and create roles that have light skin and exude confidence. For gender identity and characterization, females’ psychological sex, sexual orientation, and gender role all have significant influences on a character’s gender and class.

Secure Multi-Player Protocols

DEFF Research Database (Denmark)

Fehr, Serge

While classically cryptography is concerned with the problem of private communication among two entities, say players, in modern cryptography multi-player protocols play an important role. And among these, it is probably fair to say that secret sharing, and its stronger version verifiable secret...... sharing (VSS), as well as multi-party computation (MPC) belong to the most appealing and/or useful ones. The former two are basic tools to achieve better robustness of cryptographic schemes against malfunction or misuse by “decentralizing” the security from one single to a whole group of individuals...... (captured by the term threshold cryptography). The latter allows—at least in principle—to execute any collaboration among a group of players in a secure way that guarantees the correctness of the outcome but simultaneously respects the privacy of the participants. In this work, we study three aspects...

2010-08-05

People exert large amounts of problem-solving effort playing computer games. Simple image- and text-recognition tasks have been successfully 'crowd-sourced' through games, but it is not clear if more complex scientific problems can be solved with human-directed computing. Protein structure prediction is one such problem: locating the biologically relevant native conformation of a protein is a formidable computational challenge given the very large size of the search space. Here we describe Foldit, a multiplayer online game that engages non-scientists in solving hard prediction problems. Foldit players interact with protein structures using direct manipulation tools and user-friendly versions of algorithms from the Rosetta structure prediction methodology, while they compete and collaborate to optimize the computed energy. We show that top-ranked Foldit players excel at solving challenging structure refinement problems in which substantial backbone rearrangements are necessary to achieve the burial of hydrophobic residues. Players working collaboratively develop a rich assortment of new strategies and algorithms; unlike computational approaches, they explore not only the conformational space but also the space of possible search strategies. The integration of human visual problem-solving and strategy development capabilities with traditional computational algorithms through interactive multiplayer games is a powerful new approach to solving computationally-limited scientific problems.

Summary from the epistemic uncertainty workshop: consensus amid diversity

International Nuclear Information System (INIS)

Ferson, Scott; Joslyn, Cliff A.; Helton, Jon C.; Oberkampf, William L.; Sentz, Kari

2004-01-01

The 'Epistemic Uncertainty Workshop' sponsored by Sandia National Laboratories was held in Albuquerque, New Mexico, on 6-7 August 2002. The workshop was organized around a set of Challenge Problems involving both epistemic and aleatory uncertainty that the workshop participants were invited to solve and discuss. This concluding article in a special issue of Reliability Engineering and System Safety based on the workshop discusses the intent of the Challenge Problems, summarizes some discussions from the workshop, and provides a technical comparison among the papers in this special issue. The Challenge Problems were computationally simple models that were intended as vehicles for the illustration and comparison of conceptual and numerical techniques for use in analyses that involve: (i) epistemic uncertainty, (ii) aggregation of multiple characterizations of epistemic uncertainty, (iii) combination of epistemic and aleatory uncertainty, and (iv) models with repeated parameters. There was considerable diversity of opinion at the workshop about both methods and fundamental issues, and yet substantial consensus about what the answers to the problems were, and even about how each of the four issues should be addressed. Among the technical approaches advanced were probability theory, Dempster-Shafer evidence theory, random sets, sets of probability measures, imprecise coherent probabilities, coherent lower previsions, probability boxes, possibility theory, fuzzy sets, joint distribution tableaux, polynomial chaos expansions, and info-gap models. Although some participants maintained that a purely probabilistic approach is fully capable of accounting for all forms of uncertainty, most agreed that the treatment of epistemic uncertainty introduces important considerations and that the issues underlying the Challenge Problems are legitimate and significant. Topics identified as meriting additional research include elicitation of uncertainty representations, aggregation of

Thinking about online sources: Exploring students' epistemic cognition in internet-based chemistry learning

Science.gov (United States)

Dai, Ting

This dissertation investigated the relation between epistemic cognition---epistemic aims and source beliefs---and learning outcome in an Internet--based research context. Based on a framework of epistemic cognition (Chinn, Buckland, & Samarapungavan, 2011), a context--specific epistemic aims and source beliefs questionnaire (CEASBQ) was developed and administered to 354 students from college--level introductory chemistry courses. A series of multitrait--multimethod model comparisons provided evidence for construct convergent and discriminant validity for three epistemic aims--- true beliefs, justified beliefs, explanatory connection, which were all distinguished from, yet correlated with, mastery goals. Students' epistemic aims were specific to the chemistry topics in research. Multidimensional scaling results indicated that students' source evaluation was based on two dimensions--- professional expertise and first--hand knowledge, suggesting a multidimensional structure of source beliefs. Most importantly, online learning outcome was found to be significantly associated with two epistemic aims---justified beliefs and explanatory connection: The more students sought justifications in the online research, the lower they tended to score on the learning outcome measure, whereas the more students sought explanatory connections between information, the higher they scored on the outcome measure. There was a significant but small positive association between source beliefs and learning outcome. The influences of epistemic aims and source beliefs on learning outcome were found to be above and beyond the effects of a number of covariates, including prior knowledge and perceived ability with online sources.

Based on an empirical study of a research team in natural science, the author argues that collaborating scientists do not trust each other completely. Due to the inherent incompleteness of trust, epistemic trust among scientists is not sufficient to manage epistemic dependency in research teams....... To mitigate the limitations of epistemic trust, scientists resort to specific strategies of indirect assessment such as dialoguing practices and the probing of explanatory responsiveness. Furthermore, they rely upon impersonal trust and deploy practices of hierarchical authorship....

The Dangers of 'Warming and Replenishing' (wenbu ) during the Ming to Qing Epistemic Transition.

2015-01-01

Through a case study of Zhao Xianke's One Principle through Medicine ( Yiguan ) (1617?) and Xu Dachun's (1693-1771) denouncements of this text, my article zooms in on divergent discourses on the safety and efficacy of medicinal substances and compounds in late imperial China. Although Xu Dachun's fierce attacks on the popular 'warming and replenishing' ( wenbu ) therapies can be situated in an epistemic shift from the cosmology of 'Song learning' ( songxue ) towards the philology of 'Han learning' ( hanxue ) and 'evidential research' ( kaozheng ), I argue that more complex issues were at stake as well. Changed political, social, ethical, and economic realities shaped new and multifaceted perceptions of the nature of medicine, the medical profession, and the usage of medicinals in the aftermath of the Ming to Qing transition.

Decision making with epistemic uncertainty under safety constraints: An application to seismic design

Science.gov (United States)

Veneziano, D.; Agarwal, A.; Karaca, E.

2009-01-01

The problem of accounting for epistemic uncertainty in risk management decisions is conceptually straightforward, but is riddled with practical difficulties. Simple approximations are often used whereby future variations in epistemic uncertainty are ignored or worst-case scenarios are postulated. These strategies tend to produce sub-optimal decisions. We develop a general framework based on Bayesian decision theory and exemplify it for the case of seismic design of buildings. When temporal fluctuations of the epistemic uncertainties and regulatory safety constraints are included, the optimal level of seismic protection exceeds the normative level at the time of construction. Optimal Bayesian decisions do not depend on the aleatory or epistemic nature of the uncertainties, but only on the total (epistemic plus aleatory) uncertainty and how that total uncertainty varies randomly during the lifetime of the project. ?? 2009 Elsevier Ltd.

In games where players are competing against each other, it can be of interest to ensure that all players are challenged according to their individual skills. In order to investigate such adaptivity to the individual player in physical multi-player games, we developed a game on modular interactive...... tiles which can be used in both single-player and multi-player mode. We implemented simple adaptivity methods and tested these with different user groups including children and adults of both genders.

Surviving at any cost: guilt expression following extreme ethical conflicts in a virtual setting.

Cristofari, Cécile; Guitton, Matthieu J

2014-01-01

Studying human behavior in response to large-scale catastrophic events, particularly how moral challenges would be undertaken under extreme conditions, is an important preoccupation for contemporary scientists and decision leaders. However, researching this issue was hindered by the lack of readily available models. Immersive virtual worlds could represent a solution, by providing ways to test human behavior in controlled life-threatening situations. Using a massively multi-player zombie apocalypse setting, we analysed spontaneously reported feelings of guilt following ethically questionable actions related to survival. The occurrence and magnitude of guilt depended on the nature of the consequences of the action. Furthermore, feelings of guilt predicted long-lasting changes in behavior, displayed as compensatory actions. Finally, actions inflicting immediate harm to others appeared mostly prompted by panic and were more commonly regretted. Thus, extreme conditions trigger a reduction of the impact of ethical norms in decision making, although awareness of ethicality is retained to a surprising extent.

2009-01-01

Full Text Available This paper describes results and experiences from designing, implementing, and testing a multiplayer real-time game over mobile networks with high latency. The paper reports on network latency and bandwidth measurements from playing the game live over GPRS, EDGE, UMTS, and WLAN using the TCP and the UDP protocols. These measurements describe the practical constraints of various wireless networks and protocols when used for mobile multiplayer game purposes. Further, the paper reports on experiences from implementing various approaches to minimize issues related to high latency. Specifically, the paper focuses on a discussion about how much of the game should run locally on the client versus on the server to minimize the load on the mobile device and obtain sufficient consistency in the game. The game was designed to reveal all kinds of implementation issues of mobile network multiplayer games. The goal of the game is for a player to push other players around and into traps where they loose their lives. The game relies heavily on collision detection between the players and game objects. The paper presents experiences from experimenting with various approaches that can be used to handle such collisions, and highlights the advantages and disadvantages of the various approaches.

The Acquisition of Epistemic Modality: From Semantic Meaning to Pragmatic Interpretation

Ozturk, Ozge; Papafragou, Anna

2015-01-01

Three experiments investigated the acquisition of English epistemic modal verbs (e.g., "may", "have to"). Semantically, these verbs encode possibility or necessity with respect to available evidence. Pragmatically, the use of weak epistemic modals often gives rise to scalar conversational inferences (e.g., "The toy may be…

Latency reduction in online multiplayer games using detour routing

OpenAIRE

Ly, Cong

2010-01-01

Long network latency negatively impacts the performance of online multiplayer games. In this thesis, we propose a novel approach to reduce the network latency in online gaming. Our approach employs application level detour routing in which game-state update messages between two players can be forwarded through other intermediate relay nodes in order to reduce network latency. We present results from an extensive measurement study to show the potential benefits of detour routing in online game...

Threshold Games and Cooperation on Multiplayer Graphs.

Directory of Open Access Journals (Sweden)

Kaare B Mikkelsen

Full Text Available The study investigates the effect on cooperation in multiplayer games, when the population from which all individuals are drawn is structured-i.e. when a given individual is only competing with a small subset of the entire population.To optimize the focus on multiplayer effects, a class of games were chosen for which the payoff depends nonlinearly on the number of cooperators-this ensures that the game cannot be represented as a sum of pair-wise interactions, and increases the likelihood of observing behaviour different from that seen in two-player games. The chosen class of games are named "threshold games", and are defined by a threshold, M > 0, which describes the minimal number of cooperators in a given match required for all the participants to receive a benefit. The model was studied primarily through numerical simulations of large populations of individuals, each with interaction neighbourhoods described by various classes of networks.When comparing the level of cooperation in a structured population to the mean-field model, we find that most types of structure lead to a decrease in cooperation. This is both interesting and novel, simply due to the generality and breadth of relevance of the model-it is likely that any model with similar payoff structure exhibits related behaviour. More importantly, we find that the details of the behaviour depends to a large extent on the size of the immediate neighbourhoods of the individuals, as dictated by the network structure. In effect, the players behave as if they are part of a much smaller, fully mixed, population, which we suggest an expression for.

Role of the epistemic subject in Piaget's genetic epistemology and its importance for science education

Science.gov (United States)

Niaz, Mansoor

According to Piaget, a fundamental epistemological distinction must be made between the psychological and the epistemic subject. The epistemic subject is studied by the genetic epistemologist who charts development through a common universal rationality, which develops, whereas the psychological subject is studied by the developmental/cognitive psychologist by focusing on accidental contingencies surrounding particular people and their individual differences. The epistemic subject as compared to the psychological subject is an idealized abstraction, viz., that set of underlying epistemic structures common to everyone at the same level of development. The objective of this study is to investigate the degree to which investigators in science education conceptualize the difference between the epistemic and the psychological subjects. It is argued that just as the ideal gas law (based on the theoretical formulation of Maxwell and Boltzmann) provides a general model to which the real gases approximate under different experimental conditions, so we can consider (by abduction) the epistemic subject to be an ideal knower to which the real (psychological) subjects approximate to varying degrees. The difference between the epistemic and the psychological subjects, however, cannot be used as an epistemological shield in defense of Piagetian theory. Any test of the Piagetian theory must involve psychological or real subjects. Empirical testability, however, need not be equated to being scientific. An analogy is drawn between Galileo's idealization, which led to the discovery of the law of free-fall, and Piaget's epistemic subject. Research conducted in science education shows that at least for some critics the wide variations in the age at which individuals acquire the different Piagetian stages is crucial for rejecting the theory. It is argued that the real issue is not the proportion of heterogeneity but the understanding that Piaget, by neglecting individual differences

Lin, Feng; Chan, Carol K. K.

2018-04-01

This study examined the role of computer-supported knowledge-building discourse and epistemic reflection in promoting elementary-school students' scientific epistemology and science learning. The participants were 39 Grade 5 students who were collectively pursuing ideas and inquiry for knowledge advance using Knowledge Forum (KF) while studying a unit on electricity; they also reflected on the epistemic nature of their discourse. A comparison class of 22 students, taught by the same teacher, studied the same unit using the school's established scientific investigation method. We hypothesised that engaging students in idea-driven and theory-building discourse, as well as scaffolding them to reflect on the epistemic nature of their discourse, would help them understand their own scientific collaborative discourse as a theory-building process, and therefore understand scientific inquiry as an idea-driven and theory-building process. As hypothesised, we found that students engaged in knowledge-building discourse and reflection outperformed comparison students in scientific epistemology and science learning, and that students' understanding of collaborative discourse predicted their post-test scientific epistemology and science learning. To further understand the epistemic change process among knowledge-building students, we analysed their KF discourse to understand whether and how their epistemic practice had changed after epistemic reflection. The implications on ways of promoting epistemic change are discussed.

Socio-epistemic analysis of scientific knowledge production in little science research

Alberto Pepe

2008-12-01

Full Text Available The processes that drive knowledge production and dissemination in scientific environments are embedded within the social, technical, cultural and epistemic practices of the constituent research communities. This article presents a methodology to unpack specific social and epistemic dimensions of scientific knowledge production using, as a case study,  the Center for Embedded Networked Sensing (CENS, a National Science Foundation “little science” research center involved in theoretical and applied work in the field of wireless communication and sensor networks. By analysis of its scholarly record, I construct a social network of coauthorship, linking individuals that have coauthored scholarly artifacts (journal articles and conference papers, and an epistemic network of topic co-occurrence, linking concepts and knowledge constructs in the same scholarly artifacts. This article reports on ongoing work directed at the study of the emergence and evolution of these networks of scientific interaction. I present some preliminary results and introduce a socio-epistemic method for an historical analysis of network co-evolution. I outline a research design to support further investigations of knowledge production in scientific circles.

Shared reality in intergroup communication: Increasing the epistemic authority of an out-group audience.

Echterhoff, Gerald; Kopietz, René; Higgins, E Tory

2017-06-01

Communicators typically tune messages to their audience's attitude. Such audience tuning biases communicators' memory for the topic toward the audience's attitude to the extent that they create a shared reality with the audience. To investigate shared reality in intergroup communication, we first established that a reduced memory bias after tuning messages to an out-group (vs. in-group) audience is a subtle index of communicators' denial of shared reality to that out-group audience (Experiments 1a and 1b). We then examined whether the audience-tuning memory bias might emerge when the out-group audience's epistemic authority is enhanced, either by increasing epistemic expertise concerning the communication topic or by creating epistemic consensus among members of a multiperson out-group audience. In Experiment 2, when Germans communicated to a Turkish audience with an attitude about a Turkish (vs. German) target, the audience-tuning memory bias appeared. In Experiment 3, when the audience of German communicators consisted of 3 Turks who all held the same attitude toward the target, the memory bias again appeared. The association between message valence and memory valence was consistently higher when the audience's epistemic authority was high (vs. low). An integrative analysis across all studies also suggested that the memory bias increases with increasing strength of epistemic inputs (epistemic expertise, epistemic consensus, and audience-tuned message production). The findings suggest novel ways of overcoming intergroup biases in intergroup relations. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Networks and their traffic in multiplayer games

Full Text Available Computer games called multiplayer real-time, or (MCG are at the forefront of the use of the possibilities of the network. Research on this subject have been made for military simulations, virtual reality systems, computer support teamwork, the solutions diverge on the problems posed by MCG. With this in mind, this document provides an overview of the four issues affecting networking at the MCG. First, network resources (bandwidth, latency and computing capacity, together with the technical limits within which the MCG must operate. Second, the distribution concepts include communication architectures (peer-to-peer, client / server, server / network, and data and control architectures (centralized, distributed and reproduced .Thirdly, scalability allows the MCG to adapt to changes in parameterization resources. Finally, security is intended to fend off the traps and vandalism, which are common in online games; to check traffic, particularly these games we decided to take the massively multiplayer game League of Legends, a scene corresponding to a situation of real life in a network of ADSL access network is deployed has been simulated by using NS2 Three variants of TCP, it means SACK TCP, New Reno TCP, and TCP Vegas, have been considered for the cross traffic. The results show that TCP Vegas is able to maintain a constant speed while racing against the game traffic, since it avoids the packet loss and the delays in the tail caused by high peaks, without increasing the size of the sender window. SACK TCP and TCP New Reno, on the other hand, tend to increase continuously the sender window size, which could allow a greater loss of packages and also to cause unwanted delays for the game traffic.

Left hemisphere EEG coherence in infancy predicts infant declarative pointing and preschool epistemic language.

Science.gov (United States)

Kühn-Popp, N; Kristen, S; Paulus, M; Meinhardt, J; Sodian, B

2016-01-01

Pointing plays a central role in preverbal communication. While imperative pointing aims at influencing another person's behavior, declarative gestures serve to convey epistemic information and to share interest in an object. Further, the latter are hypothesized to be a precursor ability of epistemic language. So far, little is known about their underlying brain maturation processes. Therefore, the present study investigated the relation between brain maturation processes and the production of imperative and declarative motives as well as epistemic language in N = 32 infants. EEG coherence scores were measured at 14 months, imperative and declarative point production at 15 months and epistemic language at 48 months. Results of correlational analyses suggest distinct behavioral and neural patterns for imperative and declarative pointing, with declarative pointing being associated with the maturation of the left hemisphere. Further, EEG coherence measures of the left hemisphere at 14 months and declarative pointing at 15 months are related to individual differences in epistemic language skills at 48 months, independently of child IQ. In regression analyses, coherence measures of the left hemisphere prove to be the most important predictor of epistemic language skills. Thus, neural processes of the left hemisphere seem particularly relevant to social communication.

Comparison of China-US Engineering Ethics Educations in Sino-Western Philosophies of Technology.

Science.gov (United States)

Cao, Gui Hong

2015-12-01

Ethics education has become essential in modern engineering. Ethics education in engineering has been increasingly implemented worldwide. It can improve ethical behaviors in technology and engineering design under the guidance of the philosophy of technology. Hence, this study aims to compare China-US engineering ethics education in Sino-Western philosophies of technology by using literature studies, online surveys, observational researches, textual analyses, and comparative methods. In my original theoretical framework and model of input and output for education, six primary variables emerge in the pedagogy: disciplinary statuses, educational goals, instructional contents, didactic models, teaching methods, and edificatory effects. I focus on the similarities and differences of engineering ethics educations between China and the U.S. in Chinese and Western philosophies of technology. In the field of engineering, the U.S. tends toward applied ethics training, whereas China inclines toward practical moral education. The U.S. is the leader, particularly in the amount of money invested and engineering results. China has quickened its pace, focusing specifically on engineering labor input and output. Engineering ethics is a multiplayer game effected at various levels among (a) lower level technicians and engineers, engineering associations, and stockholders; (b) middle ranking engineering ethics education, the ministry of education, the academy of engineering, and the philosophy of technology; and (c) top national and international technological policies. I propose that professional engineering ethics education can play many important roles in reforming engineering social responsibility by international cooperation in societies that are becoming increasingly reliant on engineered devices and systems. Significantly, my proposals contribute to improving engineering ethics education and better-solving engineering ethics issues, thereby maximizing engineering

The authors draw on sociometer theory (e.g., Leary, 2004) and self-verification theory (e.g., Swann, 1997) to propose an expanded model of the regulatory function of self-esteem. The model suggests that people not only possess an acceptance signaling system that indicates whether relational value is high or low but also possess an epistemic signaling system that indicates whether social feedback is consistent or inconsistent with chronic perceived relational value (i.e., global self-esteem). One correlational study and 5 experiments, with diverse operationalizations of social feedback, demonstrated that the epistemic signaling system responds to self-esteem consistent or inconsistent relational-value feedback with increases or deceases in epistemic certainty. Moreover, Studies 3-6 demonstrated that the acceptance and epistemic signaling systems respond uniquely to social feedback. Finally, Studies 5 and 6 provide evidence that the epistemic signaling system is part of a broader self-regulatory system: Self-esteem inconsistent feedback caused cognitive efforts to decrease the discrepancy between self-views and feedback and caused depleted self-regulatory capacity on a subsequent self-control task.

Emotions as pragmatic and epistemic actions

Science.gov (United States)

Wilutzky, Wendy

2015-01-01

This paper explores the idea that emotions in social contexts and their intentionality may be conceived of as pragmatic or epistemic actions. That is, emotions are often aimed at achieving certain goals within a social context, so that they resemble pragmatic actions; and in other cases emotions can be plausibly construed as acts of probing the social environment so as to extract or uncover important information, thus complying with the functions of epistemic actions (cf. Kirsh and Maglio, 1994). This view of emotions stands at odds with the wide-held conception that emotions' intentionality can be cashed out in terms of representations of value. On such a position, emotions' intentionality has only a mind-to-world direction of fit while any world-to-mind direction of fit is deemed secondary or is even outrightly denied. However, acknowledging that emotions (qua actions) also have a world-to-mind direction fit has several advantages over the typical rendition of emotions as representations of value, such as accounting for emotions' sensitivity to contextual factors, variations in emotion expression and, importantly, assessing the appropriateness of emotional reactions. To substantiate this claim, several cases of emotions in social contexts are discussed, as the social dimension of emotions highlights that emotions are inherently ways of interacting with one's social environment. In sum, the construal of emotions in social contexts as pragmatic or epistemic actions yields a more fine-grained and accurate understanding of emotions' intentionality and their roles in social contexts than the insistence on a purely mind-to-world direction of fit.

The purpose of this study was to develop and validate two survey instruments to evaluate high school students' scientific epistemic beliefs and goal orientations in learning science. The initial relationships between the sampled students' scientific epistemic beliefs and goal orientations in learning science were also investigated. A final valid sample of 600 volunteer Taiwanese high school students participated in this survey by responding to the Scientific Epistemic Beliefs Instrument (SEBI) and the Goal Orientations in Learning Science Instrument (GOLSI). Through both exploratory and confirmatory factor analyses, the SEBI and GOLSI were proven to be valid and reliable for assessing the participants' scientific epistemic beliefs and goal orientations in learning science. The path analysis results indicated that, by and large, the students with more sophisticated epistemic beliefs in various dimensions such as Development of Knowledge, Justification for Knowing, and Purpose of Knowing tended to adopt both Mastery-approach and Mastery-avoidance goals. Some interesting results were also found. For example, the students tended to set a learning goal to outperform others or merely demonstrate competence (Performance-approach) if they had more informed epistemic beliefs in the dimensions of Multiplicity of Knowledge, Uncertainty of Knowledge, and Purpose of Knowing.

The distributed Multiplayer Online Game (MOG) system is complex since it involves technologies in computer graphics, multimedia, artificial intelligence, computer networking, embedded systems, etc. Due to the large scope of this problem, the design of MOG systems has not yet been widely addressed in the literatures. In this paper, we review and analyze the current MOG system architecture followed by evaluation. Furthermore, we propose a clustered-server architecture to provide a scalable solution together with the region oriented allocation strategy. Two key issues, i.e. interesting management and synchronization, are discussed in depth. Some preliminary ideas to deal with the identified problems are described.

Insurance Applications of Active Fault Maps Showing Epistemic Uncertainty

Science.gov (United States)

Woo, G.

2005-12-01

Insurance loss modeling for earthquakes utilizes available maps of active faulting produced by geoscientists. All such maps are subject to uncertainty, arising from lack of knowledge of fault geometry and rupture history. Field work to undertake geological fault investigations drains human and monetary resources, and this inevitably limits the resolution of fault parameters. Some areas are more accessible than others; some may be of greater social or economic importance than others; some areas may be investigated more rapidly or diligently than others; or funding restrictions may have curtailed the extent of the fault mapping program. In contrast with the aleatory uncertainty associated with the inherent variability in the dynamics of earthquake fault rupture, uncertainty associated with lack of knowledge of fault geometry and rupture history is epistemic. The extent of this epistemic uncertainty may vary substantially from one regional or national fault map to another. However aware the local cartographer may be, this uncertainty is generally not conveyed in detail to the international map user. For example, an area may be left blank for a variety of reasons, ranging from lack of sufficient investigation of a fault to lack of convincing evidence of activity. Epistemic uncertainty in fault parameters is of concern in any probabilistic assessment of seismic hazard, not least in insurance earthquake risk applications. A logic-tree framework is appropriate for incorporating epistemic uncertainty. Some insurance contracts cover specific high-value properties or transport infrastructure, and therefore are extremely sensitive to the geometry of active faulting. Alternative Risk Transfer (ART) to the capital markets may also be considered. In order for such insurance or ART contracts to be properly priced, uncertainty should be taken into account. Accordingly, an estimate is needed for the likelihood of surface rupture capable of causing severe damage. Especially where a

Active inference and epistemic value.

We offer a formal treatment of choice behavior based on the premise that agents minimize the expected free energy of future outcomes. Crucially, the negative free energy or quality of a policy can be decomposed into extrinsic and epistemic (or intrinsic) value. Minimizing expected free energy is therefore equivalent to maximizing extrinsic value or expected utility (defined in terms of prior preferences or goals), while maximizing information gain or intrinsic value (or reducing uncertainty about the causes of valuable outcomes). The resulting scheme resolves the exploration-exploitation dilemma: Epistemic value is maximized until there is no further information gain, after which exploitation is assured through maximization of extrinsic value. This is formally consistent with the Infomax principle, generalizing formulations of active vision based upon salience (Bayesian surprise) and optimal decisions based on expected utility and risk-sensitive (Kullback-Leibler) control. Furthermore, as with previous active inference formulations of discrete (Markovian) problems, ad hoc softmax parameters become the expected (Bayes-optimal) precision of beliefs about, or confidence in, policies. This article focuses on the basic theory, illustrating the ideas with simulations.

A robust Bayesian approach to modeling epistemic uncertainty in common-cause failure models

International Nuclear Information System (INIS)

Troffaes, Matthias C.M.; Walter, Gero; Kelly, Dana

2014-01-01

In a standard Bayesian approach to the alpha-factor model for common-cause failure, a precise Dirichlet prior distribution models epistemic uncertainty in the alpha-factors. This Dirichlet prior is then updated with observed data to obtain a posterior distribution, which forms the basis for further inferences. In this paper, we adapt the imprecise Dirichlet model of Walley to represent epistemic uncertainty in the alpha-factors. In this approach, epistemic uncertainty is expressed more cautiously via lower and upper expectations for each alpha-factor, along with a learning parameter which determines how quickly the model learns from observed data. For this application, we focus on elicitation of the learning parameter, and find that values in the range of 1 to 10 seem reasonable. The approach is compared with Kelly and Atwood's minimally informative Dirichlet prior for the alpha-factor model, which incorporated precise mean values for the alpha-factors, but which was otherwise quite diffuse. Next, we explore the use of a set of Gamma priors to model epistemic uncertainty in the marginal failure rate, expressed via a lower and upper expectation for this rate, again along with a learning parameter. As zero counts are generally less of an issue here, we find that the choice of this learning parameter is less crucial. Finally, we demonstrate how both epistemic uncertainty models can be combined to arrive at lower and upper expectations for all common-cause failure rates. Thereby, we effectively provide a full sensitivity analysis of common-cause failure rates, properly reflecting epistemic uncertainty of the analyst on all levels of the common-cause failure model

Epistemic interrogatives in events anchored in the temporal anteriority

Directory of Open Access Journals (Sweden)

2012-12-01

Full Text Available The present study attempts to analyse the epistemic modal functionality of temporal posteriority grammemes, referred to the “non-inactual plan”, i. e. the discourse plan measured directly from the moment of enunciation. In our opinion, the invariant category values of a verbal grameme predetermine the development of their complementary and contextual functions. Therefore, the analysis focuses also on the oppositional relations and neutralizations between the categories of verb tense, plan and perspective, on the temporal semantics and the aspectual values which maintain the oppositions between the nominal forms of the verb in accordance with the interpretation of verb categories proposed by Coseriu (1976. In this particular case, the complementary values which outline the scope of our interest fall into the parameters of the possibility and the probability (Veiga, 1991; Kitova-Vasileva, 2000, i.e. conjecture and conclusion in the field of epistemic semantics, yet with an orientation to the temporal anteriority epoch i.e. there is a conjecture regarding actions marked as prior to the moment of enunciation. The syntactic realisation of the epistemic values of conjecture is outlined in the sentence patterns of epistemic interrogatives of the type [Será que + V(P.P.S.] and [Ter(F.S. do Ind.+ V(Part.Pass.]. The study in this way goes beyond the semantic interpretation of the modal, temporal and aspectual values of the morphological instruments of conjecture, and follows the syntactic structure (the modus–dictum relations also in its discourse and pragmatic value.

Epistemic agency in an environmental sciences watershed investigation fostered by digital photography

Zimmerman, Heather Toomey; Weible, Jennifer L.

2018-05-01

This collective case study investigates the role of digital photography to support high school students' engagement in science inquiry practices during a three-week environmental sciences unit. The study's theoretical framework brings together research from digital photography, participation in environmental science practices, and epistemic agency. Data analysed include field notes and video transcripts from two groups of learners (n = 19) that focus on how high school students used digital photography during their participation in two distinct environmental monitoring practices: stream mapping and macroinvertebrate identification. Our study resulted in two findings related to the role of digital photography where students developed knowledge as they engaged in environmental monitoring inquiry practices. First, we found that digital photography was integral to the youths' epistemic agency (defined as their confidence that they could build knowledge related to science in their community) as they engaged in data collection, documenting environmental monitoring procedures, and sharing data in the classroom. Based this finding, an implication of our work is a refined view of the role of digital photography in environmental sciences education where the use of photography enhances epistemic agency in inquiry-based activities. Second, we found that the youths innovated a use of digital photography to foster a recognition that they were capable and competent in scientific procedures during a streamside study. Based on this finding, we offer a theoretical implication that expands the construct of epistemic agency; we posit that epistemic agency includes a subcomponent where the students purposefully formulate an external recognition as producers of scientific knowledge.

Values and Objectivity in Science: Value-Ladenness, Pluralism and the Epistemic Attitude

Science.gov (United States)

Carrier, Martin

2013-10-01

My intention is to cast light on the characteristics of epistemic or fundamental research (in contrast to application-oriented research). I contrast a Baconian notion of objectivity, expressing a correspondence of the views of scientists to the facts, with a pluralist notion, involving a critical debate between conflicting approaches. These conflicts include substantive hypotheses or theories but extend to values as well. I claim that a plurality of epistemic values serves to accomplish a non-Baconian form of objectivity that is apt to preserve most of the intuitions tied to the objectivity of science. For instance, pluralism is the only way to cope with the challenge of preference bias. Furthermore, the plurality of epistemic values cannot be substantially reduced by exploring the empirical success of scientific theories distinguished in light of particular such values. However, in addition to pluralism at the level of theories and value-commitments alike, scientific research is also characterized by a joint striving for consensus which I trace back to a shared epistemic attitude. This attitude manifests itself, e.g., in the willingness of scientists to subject their claims to empirical scrutiny and to respect rational argument. This shared epistemic attitude is embodied in rules adopted by the scientific community concerning general principles of dealing with knowledge claims. My contention is that pluralism and consensus formation can be brought into harmony by placing them at different levels of consideration: at the level of scientific reasoning and at the level of social conventions regarding how to deal with claims put forward within the scientific community.

Advanced Approach to Consider Aleatory and Epistemic Uncertainties for Integral Accident Simulations

International Nuclear Information System (INIS)

Peschke, Joerg; Kloos, Martina

2013-01-01

The use of best-estimate codes together with realistic input data generally requires that all potentially important epistemic uncertainties which may affect the code prediction are considered in order to get an adequate quantification of the epistemic uncertainty of the prediction as an expression of the existing imprecise knowledge. To facilitate the performance of the required epistemic uncertainty analyses, methods and corresponding software tools are available like, for instance, the GRS-tool SUSA (Software for Uncertainty and Sensitivity Analysis). However, for risk-informed decision-making, the restriction on epistemic uncertainties alone is not enough. Transients and accident scenarios are also affected by aleatory uncertainties which are due to the unpredictable nature of phenomena. It is essential that aleatory uncertainties are taken into account as well, not only in a simplified and supposedly conservative way but as realistic as possible. The additional consideration of aleatory uncertainties, for instance, on the behavior of the technical system, the performance of plant operators, or on the behavior of the physical process provides a quantification of probabilistically significant accident sequences. Only if a safety analysis is able to account for both epistemic and aleatory uncertainties in a realistic manner, it can provide a well-founded risk-informed answer for decision-making. At GRS, an advanced probabilistic dynamics method was developed to address this problem and to provide a more realistic modeling and assessment of transients and accident scenarios. This method allows for an integral simulation of complex dynamic processes particularly taking into account interactions between the plant dynamics as simulated by a best-estimate code, the dynamics of operator actions and the influence of epistemic and aleatory uncertainties. In this paper, the GRS method MCDET (Monte Carlo Dynamic Event Tree) for probabilistic dynamics analysis is explained

The epistemic integrity of scientific research.

Science.gov (United States)

De Winter, Jan; Kosolosky, Laszlo

2013-09-01

We live in a world in which scientific expertise and its epistemic authority become more important. On the other hand, the financial interests in research, which could potentially corrupt science, are increasing. Due to these two tendencies, a concern for the integrity of scientific research becomes increasingly vital. This concern is, however, hollow if we do not have a clear account of research integrity. Therefore, it is important that we explicate this concept. Following Rudolf Carnap's characterization of the task of explication, this means that we should develop a concept that is (1) similar to our common sense notion of research integrity, (2) exact, (3) fruitful, and (4) as simple as possible. Since existing concepts do not meet these four requirements, we develop a new concept in this article. We describe a concept of epistemic integrity that is based on the property of deceptiveness, and argue that this concept does meet Carnap's four requirements of explication. To illustrate and support our claims we use several examples from scientific practice, mainly from biomedical research.

Thisfeature is part of the Argentine academic tradition which goes from the origins of psychology as an undergraduate program by the end of the 1950s to the present day. In relation to this topic, four issues are analysed: a the knowledges of psychology showing the necessity of two epistemic dimensions closely related, namely the discursivity and recursivity, or knowledge and metaknowledge, b the role of psychology as a profession within the praxis, rather than in the poiesis, according to the Greek distinction between the implications of these two modalities of the “doing”, c the concurrence and difference of ethics and deontology, their roles, bounds and potentialities within the psychological field in general, and that of scientific-professional morality in particular, and d the definition and characterization of ethics and epistemology as knowledge of recursivity in psychologists’ training.

Epistemic Network Analysis is a tool developed by the epistemic games group at the University of Wisconsin Madison for tracking the relations between concepts in students discourse (Shaffer 2017). In our current work we are applying this tool to learning objectives in teachers digital preparation....... The danish mathematics curriculum is organised in six competencies and three topics. In the recently implemented learning platforms teacher choose which of the mathematical competencies that serves as objective for a specific lesson or teaching sequence. Hence learning objectives for lessons and teaching...... sequences are defining a network of competencies, where two competencies are closely related of they often are part of the same learning objective or teaching sequence. We are currently using Epistemic Network Analysis to study these networks. In the poster we will include examples of different networks...

Piaget's epistemic subject and science education: Epistemological vs. psychological issues

Science.gov (United States)

Kitchener, Richard F.

1993-06-01

Many individuals claim that Piaget's theory of cognitive development is empirically false or substantially disconfirmed by empirical research. Although there is substance to such a claim, any such conclusion must address three increasingly problematic issues about the possibility of providing an empirical test of Piaget's genetic epistemology: (1) the empirical underdetermination of theory by empirical evidence, (2) the empirical difficulty of testing competence-type explanations, and (3) the difficulty of empirically testing epistemic norms. This is especially true of a central epistemic construct in Piaget's theory — the epistemic subject. To illustrate how similar problems of empirical testability arise in the physical sciences, I briefly examine the case of Galileo and the correlative difficulty of empirically testing Galileo's laws. I then point out some important epistemological similarities between Galileo and Piaget together with correlative changes needed in science studies methodology. I conclude that many psychologists and science educators have failed to appreciate the difficulty of falsifying Piaget's theory because they have tacitly adopted a philosophy of science at odds with the paradigm-case of Galileo.

Measuring reliability under epistemic uncertainty: Review on non-probabilistic reliability metrics

Directory of Open Access Journals (Sweden)

Kang Rui

2016-06-01

Full Text Available In this paper, a systematic review of non-probabilistic reliability metrics is conducted to assist the selection of appropriate reliability metrics to model the influence of epistemic uncertainty. Five frequently used non-probabilistic reliability metrics are critically reviewed, i.e., evidence-theory-based reliability metrics, interval-analysis-based reliability metrics, fuzzy-interval-analysis-based reliability metrics, possibility-theory-based reliability metrics (posbist reliability and uncertainty-theory-based reliability metrics (belief reliability. It is pointed out that a qualified reliability metric that is able to consider the effect of epistemic uncertainty needs to (1 compensate the conservatism in the estimations of the component-level reliability metrics caused by epistemic uncertainty, and (2 satisfy the duality axiom, otherwise it might lead to paradoxical and confusing results in engineering applications. The five commonly used non-probabilistic reliability metrics are compared in terms of these two properties, and the comparison can serve as a basis for the selection of the appropriate reliability metrics.

Then we analyze specific protocols for complete graphs and for directed rings.

Epistemic beliefs of middle and high school students in a problem-based, scientific inquiry unit: An exploratory, mixed methods study

Science.gov (United States)

Gu, Jiangyue

Epistemic beliefs are individuals' beliefs about the nature of knowledge, how knowledge is constructed, and how knowledge can be justified. This study employed a mixed-methods approach to examine: (a) middle and high school students' self-reported epistemic beliefs (quantitative) and epistemic beliefs revealed from practice (qualitative) during a problem-based, scientific inquiry unit, (b) How do middle and high school students' epistemic beliefs contribute to the construction of students' problem solving processes, and (c) how and why do students' epistemic beliefs change by engaging in PBL. Twenty-one middle and high school students participated in a summer science class to investigate local water quality in a 2-week long problem-based learning (PBL) unit. The students worked in small groups to conduct water quality tests at in their local watershed and visited several stakeholders for their investigation. Pretest and posttest versions of the Epistemological Beliefs Questionnaire were conducted to assess students' self-reported epistemic beliefs before and after the unit. I videotaped and interviewed three groups of students during the unit and conducted discourse analysis to examine their epistemic beliefs revealed from scientific inquiry activities and triangulate with their self-reported data. There are three main findings from this study. First, students in this study self-reported relatively sophisticated epistemic beliefs on the pretest. However, the comparison between their self-reported beliefs and beliefs revealed from practice indicated that some students were able to apply sophisticated beliefs during the unit while others failed to do so. The inconsistency between these two types of epistemic beliefs may due to students' inadequate cognitive ability, low validity of self-report measure, and the influence of contextual factors. Second, qualitative analysis indicated that students' epistemic beliefs of the nature of knowing influenced their problem

Fuzzy probability based fault tree analysis to propagate and quantify epistemic uncertainty

International Nuclear Information System (INIS)

Purba, Julwan Hendry; Sony Tjahyani, D.T.; Ekariansyah, Andi Sofrany; Tjahjono, Hendro

2015-01-01

Highlights: • Fuzzy probability based fault tree analysis is to evaluate epistemic uncertainty in fuzzy fault tree analysis. • Fuzzy probabilities represent likelihood occurrences of all events in a fault tree. • A fuzzy multiplication rule quantifies epistemic uncertainty of minimal cut sets. • A fuzzy complement rule estimate epistemic uncertainty of the top event. • The proposed FPFTA has successfully evaluated the U.S. Combustion Engineering RPS. - Abstract: A number of fuzzy fault tree analysis approaches, which integrate fuzzy concepts into the quantitative phase of conventional fault tree analysis, have been proposed to study reliabilities of engineering systems. Those new approaches apply expert judgments to overcome the limitation of the conventional fault tree analysis when basic events do not have probability distributions. Since expert judgments might come with epistemic uncertainty, it is important to quantify the overall uncertainties of the fuzzy fault tree analysis. Monte Carlo simulation is commonly used to quantify the overall uncertainties of conventional fault tree analysis. However, since Monte Carlo simulation is based on probability distribution, this technique is not appropriate for fuzzy fault tree analysis, which is based on fuzzy probabilities. The objective of this study is to develop a fuzzy probability based fault tree analysis to overcome the limitation of fuzzy fault tree analysis. To demonstrate the applicability of the proposed approach, a case study is performed and its results are then compared to the results analyzed by a conventional fault tree analysis. The results confirm that the proposed fuzzy probability based fault tree analysis is feasible to propagate and quantify epistemic uncertainties in fault tree analysis

Conditional Epistemic Planning

Andersen, Mikkel Birkegaard; Bolander, Thomas; Jensen, Martin Holm

2012-01-01

Recent work has shown that Dynamic Epistemic Logic (DEL) offers a solid foundation for automated planning under partial observability and non-determinism. Under such circumstances, a plan must branch if it is to guarantee achieving the goal under all contingencies (strong planning). Without...... branching, plans can offer only the possibility of achieving the goal (weak planning). We show how to formulate planning in uncertain domains using DEL and give a language of conditional plans. Translating this language to standard DEL gives verification of both strong and weak plans via model checking....... In addition to plan verification, we provide a tableau-inspired algorithm for synthesising plans, and show this algorithm to be terminating, sound and complete....

Mapping epistemic cultures and learning potential of participants in citizen science projects.

Vallabh, Priya; Lotz-Sisitka, Heila; O'Donoghue, Rob; Schudel, Ingrid

2016-06-01

The ever-widening scope and range of global change and interconnected systemic risks arising from people-environment relationships (social-ecological risks) appears to be increasing concern among, and involvement of, citizens in an increasingly diversified number of citizen science projects responding to these risks. We examined the relationship between epistemic cultures in citizen science projects and learning potential related to matters of concern. We then developed a typology of purposes and a citizen science epistemic-cultures heuristic and mapped 56 projects in southern Africa using this framework. The purpose typology represents the range of knowledge-production purposes, ranging from laboratory science to social learning, whereas the epistemic-cultures typology is a relational representation of scientist and citizen participation and their approach to knowledge production. Results showed an iterative relationship between matters of fact and matters of concern across the projects; the nexus of citizens' engagement in knowledge-production activities varied. The knowledge-production purposes informed and shaped the epistemic cultures of all the sampled citizen science projects, which in turn influenced the potential for learning within each project. Through a historical review of 3 phases in a long-term river health-monitoring project, we found that it is possible to evolve the learning curve of citizen science projects. This evolution involved the development of scientific water monitoring tools, the parallel development of pedagogic practices supporting monitoring activities, and situated engagement around matters of concern within social activism leading to learning-led change. We conclude that such evolutionary processes serve to increase potential for learning and are necessary if citizen science is to contribute to wider restructuring of the epistemic culture of science under conditions of expanding social-ecological risk. © 2016 Society for

Decoherence Effects on Multiplayer Cooperative Quantum Games

We study the behavior of cooperative multiplayer quantum games [Q. Chen, Y. Wang, J.T. Liu, and K.L. Wang, Phys. Lett. A 327 (2004) 98; A.P. Flitney and L.C.L. Hollenberg, Quantum Inf. Comput. 7 (2007) 111] in the presence of decoherence using different quantum channels such as amplitude damping, depolarizing and phase damping. It is seen that the outcomes of the games for the two damping channels with maximum values of decoherence reduce to same value. However, in comparison to phase damping channel, the payoffs of cooperators are strongly damped under the influence amplitude damping channel for the lower values of decoherence parameter. In the case of depolarizing channel, the game is a no-payoff game irrespective of the degree of entanglement in the initial state for the larger values of decoherence parameter. The decoherence gets the cooperators worse off. (general)

Terminology Evolution and Translation: Specificity of Referent & User’s Epistemic Continuum Exemplified in Islamic Terms

Directory of Open Access Journals (Sweden)

Omar A. S. Al-Shabab

2016-01-01

Full Text Available In the dynamics of environmental context, the referent of a linguistic sign changes, but the sign persists as a verbal symbol. Since a technical term strictly evokes one referent, it may lack in specificity due to the ever-changing reality, resulting in homonymy, overlap, and a semantic continuum based on designating by necessity. In addition to the elements of reference theory, the criteria for technical terms postulate the user, whose authority and responsibility are necessary for the term to function as a specific designator. The centrality of the user, translator or otherwise, has hermeneutic and linguistic implications for the evolution of terminology, because it stipulates that terminological meaning and usage are dependent on the user’s conscious knowledge, a condition that leads to the recognition of a user epistemic continuum parallel to the semantic necessity continuum. Ideally, a term should be universally specific in reference, and its user should be epistemologically empowered and ethically responsible.

Causal and Epistemic Relevance in Appeals to Authority

Directory of Open Access Journals (Sweden)

Sebastiano Lommi

2015-05-01

Full Text Available Appeals to authority have a long tradition in the history of argumentation theory. During the Middle Age they were considered legitimate and sound arguments, but after Locke’s treatment in the Essay Concerning Human Understanding their legitimacy has come under question. Traditionally, arguments from authority were considered informal arguments, but since the important work of Charles Hamblin (Hamblin, 1970 many attempts to provide a form for them have been done. The most convincing of them is the presumptive form developed by Douglas Walton and John Woods (Woods, Walton, 1974 that aims at taking into account the relevant contextual aspects in assessing the provisional validity of an appeal to authority. The soundness of an appeal depends on its meeting the adequacy conditions set to scrutinize all the relevant questions. I want to claim that this approach is compatible with the analysis of arguments in terms of relevance advanced by David Hitchcock (Hitchcock, 1992. He claims that relevance is a triadic relation between two items and a context. The first item is relevant to the second one in a given context. Different types of relevance relation exist, namely causal relevance and epistemic relevance. “Something is [causally] relevant to an outcome in a given situation if it helps to cause that outcome in the situation” (Hitchcock, 1992, p. 253, whereas it is epistemically relevant when it helps to achieve an epistemic goal in a given situation. I claim that we can adapt this conception to Walton and Krabbe’s theory of dialogue type (Walton, Krabbe, 1995, seeing the items of a relevance relation as the argument and its consequence and the context as the type of dialogue in which these arguments are advanced. According to this perspective, an argument from authority that meets the adequacy conditions has to be considered legitimate because it is an epistemically relevant relation. Therefore, my conclusion is that an analysis of appeals to

Epistemic beliefs' role in promoting misperceptions and conspiracist ideation.

Directory of Open Access Journals (Sweden)

R Kelly Garrett

Full Text Available Widespread misperceptions undermine citizens' decision-making ability. Conclusions based on falsehoods and conspiracy theories are by definition flawed. This article demonstrates that individuals' epistemic beliefs-beliefs about the nature of knowledge and how one comes to know-have important implications for perception accuracy. The present study uses a series of large, nationally representative surveys of the U.S. population to produce valid and reliable measures of three aspects of epistemic beliefs: reliance on intuition for factual beliefs (Faith in Intuition for facts, importance of consistency between empirical evidence and beliefs (Need for evidence, and conviction that "facts" are politically constructed (Truth is political. Analyses confirm that these factors complement established predictors of misperception, substantively increasing our ability to explain both individuals' propensity to engage in conspiracist ideation, and their willingness to embrace falsehoods about high-profile scientific and political issues. Individuals who view reality as a political construct are significantly more likely to embrace falsehoods, whereas those who believe that their conclusions must hew to available evidence tend to hold more accurate beliefs. Confidence in the ability to intuitively recognize truth is a uniquely important predictor of conspiracist ideation. Results suggest that efforts to counter misperceptions may be helped by promoting epistemic beliefs emphasizing the importance of evidence, cautious use of feelings, and trust that rigorous assessment by knowledgeable specialists is an effective guard against political manipulation.

The epistemic-teleologic model of deliberate self-persuasion.

Science.gov (United States)

Maio, Gregory R; Thomas, Geoff

2007-02-01

Although past theory and research point to the importance of understanding deliberate self-persuasion (i.e., deliberate self-induced attitude change), there have been no empirical and theoretical efforts to model this process. This article proposes a new model to help understand the process, while comparing the process of deliberate self-persuasion with relevant theory and research. The core feature of this model is a distinction between epistemic processes, which involve attempting to form new valid attitudes, and teleologic processes, which involve self-induced attitude change but with minimal concerns for validity. The epistemic processes employ tactics of reinterpretation, reattribution, reintegration, retesting, changing comparators, and changing dimensions of comparison. The teleologic processes include suppression, preemption, distraction, and concentration. By mapping these processes, this model helps to generate many novel and testable hypotheses about the use of deliberate self-persuasion to cope with ambivalent attitudes.

Relative Values: Perspectives on a Neuroimaging Technology From Above and Within the Ethical Landscape.

Science.gov (United States)

Samuel, Gabrielle; Cribb, Alan; Owens, John; Williams, Clare

2016-09-01

In this paper we contribute to "sociology in bioethics" and help clarify the range of ways sociological work can contribute to ethics scholarship. We do this using a case study of an innovative neurotechnology, functional magnetic resonance imaging, and its use to attempt to diagnose and communicate with severely brain-injured patients. We compare empirical data from interviews with relatives of patients who have a severe brain injury with perspectives from mainstream bioethics scholars. We use the notion of an "ethical landscape" as an analogy for the different ethical positions subjects can take-whereby a person's position relative to the landscape makes a difference to the way they experience and interact with it. We show that, in comparison to studying abstract ethics "from above" the ethical landscape, which involves universal generalizations and global judgements, studying ethics empirically "from the ground," within the ethical landscape foregrounds a more plural and differentiated picture. We argue it is important not to treat empirical ethics as secondary to abstract ethics, to treat on-the-ground perspectives as useful only insofar as they can inform ethics from above. Rather, empirical perspectives can illuminate the plural vantage points in ethical judgments, highlight the "lived" nature of ethical reasoning, and point to all ethical vantage points as being significant. This is of epistemic importance to normative ethics, since researchers who pay attention to the various positions in and trajectories through the ethical landscape are unlikely to think about ethics in terms of abstract agency-as can happen with top-down ethics-or to elide agency with the agency of policymakers. Moreover, empirical perspectives may have transformative implications for people on the ground, especially where focus on the potential harms and benefits they face brings their experiences and interests to the forefront of ethical and policy discussion.

Postpartum hemorrhage (PPH) remains a global challenge, affecting thirteen million women each year. In addition, PPH is a leading cause of maternal mortality in Asia and Africa. In the U.S.A., care of critically ill patients is often practiced using mannequin-based simulation. Mannequin-based simulation presents challenges in global health, particularly in low- or middle-income countries. We developed a novel multiplayer screen-based simulation in a virtual world enabling the practice of team coordination with PPH. We used this simulation with learners in Mulago, Uganda. We hypothesized that a multiplayer screen-based simulation experience would increase learner confidence in their ability to manage PPH. The study design was a simple pre- and a post-intervention survey. Forty-eight interprofessional subjects participated in one of nine 1-h simulation sessions using the PPH software. A fifteen-question self-assessment administered before and after the intervention was designed to probe the areas of learning as defined by Bloom and Krathwohl: affective, cognitive, and psychomotor. Combined confidence scores increased significantly overall following the simulation experience and individually in each of the three categories of Bloom's Taxonomy: affective, cognitive, and psychomotor. We provide preliminary evidence that multiplayer screen-based simulation represents a scalable, distributable form of learning that may be used effectively in global health education and training. Interestingly, despite our intervention being screen-based, our subjects showed improved confidence in their ability to perform psychomotor tasks. Although there is precedent for mental rehearsal improving performance, further research is needed to understand this finding.

The Epistemic Inferiority of Pragma-Dialectics – Reply to Botting

Directory of Open Access Journals (Sweden)

Christoph Lumer

2012-03-01

Full Text Available In a recent paper in this journal, David Botting defended pragma-dialectics against epistemological criticisms by exponents of the epistemological approach to argumentation, i.e. Harvey Siegel, John Biro and me. In particular, Botting tries to justify with new arguments a Functional Claim, that the function of argumentation is to resolve disputes, and a Normative Claim, that standpoints that have the unqualified consensus of all participants in a dispute will generally be epistemically sound. In this reply it is shown that Botting’s arguments are fallacious, that the two Claims are false and that the epistemological approach to argumentation, of course, outclasses pragma-dialectics epistemically and is at least as good as it in other respects.

The Ethics of Belief, Cognition, and Climate Change Pseudoskepticism: Implications for Public Discourse.

Science.gov (United States)

Torcello, Lawrence

2016-01-01

The relationship between knowledge, belief, and ethics is an inaugural theme in philosophy; more recently, under the title "ethics of belief" philosophers have worked to develop the appropriate methodology for studying the nexus of epistemology, ethics, and psychology. The title "ethics of belief" comes from a 19th-century paper written by British philosopher and mathematician W.K. Clifford. Clifford argues that we are morally responsible for our beliefs because (a) each belief that we form creates the cognitive circumstances for related beliefs to follow, and (b) we inevitably influence each other through those beliefs. This study argues that recent cognitive research supports Cliffordian insights regarding patterns of belief formation and social influence. From the confirmation offered by such research, it follows that informational accuracy holds serious ethical significance in public discourse. Although scientific and epistemological matters are not always thought to be linked to normative morality, this study builds on Clifford's initial insights to show their linkage is fundamental to inquiry itself. In turn, Clifford's ethical and epistemic outline can inform a framework grounded in "public reason" under which seemingly opposed science communication strategies (e.g., "information deficit" and "cultural cognition" models) are philosophically united. With public discourse on climate change as the key example, empirically informed and grounded strategies for science communication in the public sphere are considered.

[Science, public health and nursing: highlighting the gender and generation categories in the episteme of praxis].

Egry, Emiko Yoshikawa; da Fonseca, Rosa Maria Godoy Serpa; Oliveira, Maria Amélia de Campos

2013-09-01

This essay aims to show the relevance of sociological categories gender and generation that underlie the phenomenon of nursing in public health, the episteme of praxis. We understand praxis as the foundation of the historical and dialectic materialism, demonstrating its importance in the process of construction of knowledge in public health nursing. The sociological categories of gender and generation were chosen in this paper because it has the privilege to better illuminate certain phenomena that have been the subject of scientific concern, such as violence against women, children and the elderly, in all its vulnerabilities. The dialectical method was adopted, with an emphasis on the secondary laws of "essence and phenomena" and "reality and possibility". Finally, given that the choice of the approach to the object, as well as the instruments for intervention towards a purpose in the process of scientific knowledge is the choice of the knowing subject, the ethics was related to praxis.

Epistemic motivation affects the processing of negative emotional stimuli in interpersonal decisions

Directory of Open Access Journals (Sweden)

Zhenyu eWei

2015-07-01

Full Text Available The present electrophysiological study investigated the role of the need for cognitive closure (NFC in emotional processing. The NFC is conceptualized as an epistemic motive that is related to how and why people seek out information in social environments. Event-related potentials were recorded while individuals with high NFC (i.e., low epistemic motivation or low NFC (i.e., high epistemic motivation performed a modified Ultimatum Game, in which the emotions of happy or angry game agents were employed to predict their most likely offer. High-NFC participants more closely adhered to the decisions rules of the game than low-NFC individuals did. The electrophysiological results showed that the dispositional NFC modified early perceptual components (N170, N200, and P200. The potentials showed that high-NFC subjects had a processing bias to angry faces, whereas low-NFC individuals exhibited no such effects. These findings indicated that high-NFC individuals were more sensitive to negative emotional stimuli than low-NFC individuals in an interpersonal decision-making task.

Adverbial Markers of Epistemic Modality Across Disciplinary Discourses: A Contrastive Study of Research Articles in Six Academic Disciplines

Directory of Open Access Journals (Sweden)

Rozumko Agata

2017-03-01

Full Text Available Epistemic adverbs, like other markers of epistemic modality, are concerned with the speaker’s assessment of the truth value of the proposition. In other words, they indicate that the speaker considers certain situations as possible, impossible, probable, certain, or uncertain. At the same time, they signal the author’s presence in the text, and invite the reader to make his/her own conclusions and interpretations. The use of modal markers has been demonstrated to differ across academic disciplines, but the specific differences concerning the use of epistemic adverbs have not been studied systematically. This paper investigates the use of epistemic adverbs in research articles representing six disciplines belonging to three different branches of science: the humanities (linguistics and literary studies, the social sciences (law and sociology, and the natural sciences (physics and medicine, with the aim of establishing discipline-specific tendencies in their use. The study is based on a corpus of 160 research articles compiled by the author. It begins with an attempt at delimiting the category of epistemic adverbs in English. After that, a list of the most frequent epistemic adverbs in the subcorpora of all the disciplines is established and discussed. The study demonstrates that frequent use of epistemic adverbs is largely a property of research articles in the humanities and social sciences. Medical and physics research articles use them significantly less often. The most frequent epistemic adverbs in the research articles under analysis include indeed, perhaps, clearly, certainly, of course, arguably, possibly, and reportedly. Some adverbs appear to be associated with specific disciplines, e.g., clearly (physics, linguistics, sociology, medicine, indeed (linguistics, literary studies, sociology, possibly, reportedly (medicine, arguably (law. The association of individual adverbs with specific disciplines may serve as an important clue to

Recently, the study of structured populations using models of evolutionary processes on graphs has begun to incorporate a more general type of interaction between individuals, allowing multi-player games to be played among the population. In this paper, we develop a birth-death dynamics for use in such models and consider the evolution of populations for special cases of very small graphs where we can easily identify all of the population states and carry out exact analyses. To do so, we study two multi-player games, a Hawk-Dove game and a public goods game. Our focus is on finding the fixation probability of an individual from one type, cooperator or defector in the case of the public goods game, within a population of the other type. We compare this value for both games on several graphs under different parameter values and assumptions, and identify some interesting general features of our model. In particular there is a very close relationship between the fixation probability and the mean temperature, with high temperatures helping fitter individuals and punishing unfit ones and so enhancing selection, whereas low temperatures give a levelling effect which suppresses selection.

Accounting for Epistemic Uncertainty in Mission Supportability Assessment: A Necessary Step in Understanding Risk and Logistics Requirements

Owens, Andrew; De Weck, Olivier L.; Stromgren, Chel; Goodliff, Kandyce; Cirillo, William

2017-01-01

Future crewed missions to Mars present a maintenance logistics challenge that is unprecedented in human spaceflight. Mission endurance – defined as the time between resupply opportunities – will be significantly longer than previous missions, and therefore logistics planning horizons are longer and the impact of uncertainty is magnified. Maintenance logistics forecasting typically assumes that component failure rates are deterministically known and uses them to represent aleatory uncertainty, or uncertainty that is inherent to the process being examined. However, failure rates cannot be directly measured; rather, they are estimated based on similarity to other components or statistical analysis of observed failures. As a result, epistemic uncertainty – that is, uncertainty in knowledge of the process – exists in failure rate estimates that must be accounted for. Analyses that neglect epistemic uncertainty tend to significantly underestimate risk. Epistemic uncertainty can be reduced via operational experience; for example, the International Space Station (ISS) failure rate estimates are refined using a Bayesian update process. However, design changes may re-introduce epistemic uncertainty. Thus, there is a tradeoff between changing a design to reduce failure rates and operating a fixed design to reduce uncertainty. This paper examines the impact of epistemic uncertainty on maintenance logistics requirements for future Mars missions, using data from the ISS Environmental Control and Life Support System (ECLS) as a baseline for a case study. Sensitivity analyses are performed to investigate the impact of variations in failure rate estimates and epistemic uncertainty on spares mass. The results of these analyses and their implications for future system design and mission planning are discussed.

Exploring the relationships between epistemic beliefs about medicine and approaches to learning medicine: a structural equation modeling analysis.

Students' epistemic beliefs may vary in different domains; therefore, it may be beneficial for medical educators to better understand medical students' epistemic beliefs regarding medicine. Understanding how medical students are aware of medical knowledge and how they learn medicine is a critical issue of medical education. The main purposes of this study were to investigate medical students' epistemic beliefs relating to medical knowledge, and to examine their relationships with students' approaches to learning medicine. A total of 340 undergraduate medical students from 9 medical colleges in Taiwan were surveyed with the Medical-Specific Epistemic Beliefs (MSEB) questionnaire (i.e., multi-source, uncertainty, development, justification) and the Approach to Learning Medicine (ALM) questionnaire (i.e., surface motive, surface strategy, deep motive, and deep strategy). By employing the structural equation modeling technique, the confirmatory factor analysis and path analysis were conducted to validate the questionnaires and explore the structural relations between these two constructs. It was indicated that medical students with multi-source beliefs who were suspicious of medical knowledge transmitted from authorities were less likely to possess a surface motive and deep strategies. Students with beliefs regarding uncertain medical knowledge tended to utilize flexible approaches, that is, they were inclined to possess a surface motive but adopt deep strategies. Students with beliefs relating to justifying medical knowledge were more likely to have mixed motives (both surface and deep motives) and mixed strategies (both surface and deep strategies). However, epistemic beliefs regarding development did not have significant relations with approaches to learning. Unexpectedly, it was found that medical students with sophisticated epistemic beliefs (e.g., suspecting knowledge from medical experts) did not necessarily engage in deep approaches to learning medicine

Third, although epistemic uncertainty did not predict the information that was eventually selected to take forward in the design space, both immediate creative elaboration and subsequent...

Quantum mechanics as classical statistical mechanics with an ontic extension and an epistemic restriction.

Science.gov (United States)

Budiyono, Agung; Rohrlich, Daniel

2017-11-03

Where does quantum mechanics part ways with classical mechanics? How does quantum randomness differ fundamentally from classical randomness? We cannot fully explain how the theories differ until we can derive them within a single axiomatic framework, allowing an unambiguous account of how one theory is the limit of the other. Here we derive non-relativistic quantum mechanics and classical statistical mechanics within a common framework. The common axioms include conservation of average energy and conservation of probability current. But two axioms distinguish quantum mechanics from classical statistical mechanics: an "ontic extension" defines a nonseparable (global) random variable that generates physical correlations, and an "epistemic restriction" constrains allowed phase space distributions. The ontic extension and epistemic restriction, with strength on the order of Planck's constant, imply quantum entanglement and uncertainty relations. This framework suggests that the wave function is epistemic, yet it does not provide an ontic dynamics for individual systems.

Ethical and epistemic issues in direct-to-consumer drug advertising: where is patient agency?

Science.gov (United States)

Womack, Catherine A

2013-05-01

Arguments for and against direct-to-consumer drug advertising (DTCA) center on two issues: (1) the epistemic effects on patients through access to information provided by the ads; and (2) the effects of such information on patients' abilities to make good choices in the healthcare marketplace. Advocates argue that DTCA provides useful information for patients as consumers, including information connecting symptoms to particular medical conditions, information about new drug therapies for those conditions. Opponents of DTCA point out substantial omissions in information provided by the ads and argue that the framing of the ads may mislead patients about the indications, uses, and effectiveness of the drugs advertised. They also suggest that DTCA has a number of potentially negative effects on the doctor-patient relationship. The standard arguments appear to assume a simplistic correlation-more information means more agency for patients. However, empirical studies on medical decision making suggest that this relationship is much more complex and nuanced. I examine recent research on ways in which patients are vulnerable with respect to DTCA. In order to address the complex issues of information acquisition and consumer decision-making in the health care marketplace, the focus should not be simply on what information patients need in order to make medical decisions, but also on the conditions under which patients actually are able to make medical decisions requiring complex medication information. This requires examining both the cognitive limitations of patients with respect to drug information and investigating patients' preferences and needs in a variety of medical contexts.

When one model is not enough: combining epistemic tools in systems biology.

Science.gov (United States)

Green, Sara

2013-06-01

In recent years, the philosophical focus of the modeling literature has shifted from descriptions of general properties of models to an interest in different model functions. It has been argued that the diversity of models and their correspondingly different epistemic goals are important for developing intelligible scientific theories (Leonelli, 2007; Levins, 2006). However, more knowledge is needed on how a combination of different epistemic means can generate and stabilize new entities in science. This paper will draw on Rheinberger's practice-oriented account of knowledge production. The conceptual repertoire of Rheinberger's historical epistemology offers important insights for an analysis of the modelling practice. I illustrate this with a case study on network modeling in systems biology where engineering approaches are applied to the study of biological systems. I shall argue that the use of multiple representational means is an essential part of the dynamic of knowledge generation. It is because of-rather than in spite of-the diversity of constraints of different models that the interlocking use of different epistemic means creates a potential for knowledge production.

Interferences and events on epistemic shifts in physics through computer simulations

CERN Document Server

Warnke, Martin

2017-01-01

Computer simulations are omnipresent media in today's knowledge production. For scientific endeavors such as the detection of gravitational waves and the exploration of subatomic worlds, simulations are essential; however, the epistemic status of computer simulations is rather controversial as they are neither just theory nor just experiment. Therefore, computer simulations have challenged well-established insights and common scientific practices as well as our very understanding of knowledge. This volume contributes to the ongoing discussion on the epistemic position of computer simulations in a variety of physical disciplines, such as quantum optics, quantum mechanics, and computational physics. Originating from an interdisciplinary event, it shows that accounts of contemporary physics can constructively interfere with media theory, philosophy, and the history of science.

Recently, there have been growing concerns about excessive online gaming. Playing Massively Multiplayer Online Role-Playing Games (MMORPGs) appears to be particularly problematic, because these games require a high degree of commitment and time investment from the players to the detriment of occupational, social, and other recreational activities and relations. A number of gaming motives have been linked to excessive online gaming in adolescents and young adults. We assessed 175 current MMORP...

Fluctuating Epistemic Uncertainty in a Design Team as a Metacognitive Driver for Creative Cognitive Processes

DEFF Research Database (Denmark)

Christensen, Bo; Ball, Linden J.

Previous design research has demonstrated how epistemic uncertainty engenders localised, creative reasoning, including analogising and mental simulation. We analysed not just the short-term, localised effects of epistemic uncertainty on creative processing and information selection, but also its...... long-term impact on downstream creative processes. Our hypothesis was that heightened levels of uncertainty associated with a particular cognitive referent would engender: (1) immediate creative elaboration of that referent aimed at resolving uncertainty and determining information selection; and (2...

Weak values in a classical theory with an epistemic restriction

International Nuclear Information System (INIS)

Karanjai, Angela; Cavalcanti, Eric G; Bartlett, Stephen D; Rudolph, Terry

2015-01-01

Weak measurement of a quantum system followed by postselection based on a subsequent strong measurement gives rise to a quantity called the weak value: a complex number for which the interpretation has long been debated. We analyse the procedure of weak measurement and postselection, and the interpretation of the associated weak value, using a theory of classical mechanics supplemented by an epistemic restriction that is known to be operationally equivalent to a subtheory of quantum mechanics. Both the real and imaginary components of the weak value appear as phase space displacements in the postselected expectation values of the measurement device's position and momentum distributions, and we recover the same displacements as in the quantum case by studying the corresponding evolution in our theory of classical mechanics with an epistemic restriction. By using this epistemically restricted theory, we gain insight into the appearance of the weak value as a result of the statistical effects of post selection, and this provides us with an operational interpretation of the weak value, both its real and imaginary parts. We find that the imaginary part of the weak value is a measure of how much postselection biases the mean phase space distribution for a given amount of measurement disturbance. All such biases proportional to the imaginary part of the weak value vanish in the limit where disturbance due to measurement goes to zero. Our analysis also offers intuitive insight into how measurement disturbance can be minimized and the limits of weak measurement. (paper)

For reflexivity as an epistemic criterion of ontological coherence and virtuous social theorizing.

Science.gov (United States)

Bouzanis, Christoforos

2017-12-01

This article offers an approach that combines, on the one hand, the philosophical notion of reflexivity, which is related to the ideas of self-reference and paradox, and, on the other hand, the sociological discussion of epistemic reflexivity as a problem of coherence, which was mainly initiated by certain branches of ethnomethodology and social constructionism. This combinatory approach argues for reflexivity as an epistemic criterion of ontological coherence , which suggests that social ontologies should account for the possibility of self-reflective subjectivity - for otherwise they result in a paradoxical conclusion according to which a social scientist reflects on her or his ontological commitments even though these commitments deny her or him the capacity for self-reflection . This analysis presupposes that all human sciences are categorically premised on social ontologies; and it argues for an analytical distinction between self-reflection, which refers to the agential capacity for reflecting on one's own commitments, and the epistemic criterion of reflexivity hereby proposed. These two analytically distinct though interdependent socio-theoretical concepts are frequently conflated in the literature; thus, this article also aims at a 'clearing of the ground' that can be of categorical use to the human sciences.

ψ-Epistemic Models are Exponentially Bad at Explaining the Distinguishability of Quantum States

Science.gov (United States)

Leifer, M. S.

2014-04-01

The status of the quantum state is perhaps the most controversial issue in the foundations of quantum theory. Is it an epistemic state (state of knowledge) or an ontic state (state of reality)? In realist models of quantum theory, the epistemic view asserts that nonorthogonal quantum states correspond to overlapping probability measures over the true ontic states. This naturally accounts for a large number of otherwise puzzling quantum phenomena. For example, the indistinguishability of nonorthogonal states is explained by the fact that the ontic state sometimes lies in the overlap region, in which case there is nothing in reality that could distinguish the two states. For this to work, the amount of overlap of the probability measures should be comparable to the indistinguishability of the quantum states. In this Letter, I exhibit a family of states for which the ratio of these two quantities must be ≤2de-cd in Hilbert spaces of dimension d that are divisible by 4. This implies that, for large Hilbert space dimension, the epistemic explanation of indistinguishability becomes implausible at an exponential rate as the Hilbert space dimension increases.

Students' Scientific Epistemic Beliefs, Online Evaluative Standards, and Online Searching Strategies for Science Information: The Moderating Role of Cognitive Load Experience

Science.gov (United States)

Hsieh, Ya-Hui; Tsai, Chin-Chung

2014-06-01

The purpose of this study is to examine the moderating role of cognitive load experience between students' scientific epistemic beliefs and information commitments, which refer to online evaluative standards and online searching strategies. A total of 344 science-related major students participated in this study. Three questionnaires were used to ascertain the students' scientific epistemic beliefs, information commitments, and cognitive load experience. Structural equation modeling was then used to analyze the moderating effect of cognitive load, with the results revealing its significant moderating effect. The relationships between sophisticated scientific epistemic beliefs and the advanced evaluative standards used by the students were significantly stronger for low than for high cognitive load students. Moreover, considering the searching strategies that the students used, the relationships between sophisticated scientific epistemic beliefs and advanced searching strategies were also stronger for low than for high cognitive load students. However, for the high cognitive load students, only one of the sophisticated scientific epistemic belief dimensions was found to positively associate with advanced evaluative standard dimensions.

Social interactions in massively multiplayer online role-playing gamers.

Cole, Helena; Griffiths, Mark D

2007-08-01

To date, most research into massively multiplayer online role-playing games (MMORPGs) has examined the demographics of play. This study explored the social interactions that occur both within and outside of MMORPGs. The sample consisted of 912 self-selected MMORPG players from 45 countries. MMORPGs were found to be highly socially interactive environments providing the opportunity to create strong friendships and emotional relationships. The study demonstrated that the social interactions in online gaming form a considerable element in the enjoyment of playing. The study showed MMORPGs can be extremely social games, with high percentages of gamers making life-long friends and partners. It was concluded that virtual gaming may allow players to express themselves in ways they may not feel comfortable doing in real life because of their appearance, gender, sexuality, and/or age. MMORPGs also offer a place where teamwork, encouragement, and fun can be experienced.

The Epistemic Dimension of Competence in the Social Sciences

Directory of Open Access Journals (Sweden)

Liliana Maggioni

2010-12-01

Full Text Available To investigate competence in the social sciences, we propose to define competence as a particular configuration of the learner’s cognition, strategic repertoire, motivation, and orientation toward knowing. Specifically, we focus on epistemic beliefs and on the changes that a view of knowing as a complex, effortful, generative, evidence-seeking, and reflective enterprise entails. In this context, we discuss how familiarity with the processes used to justify knowledge claims within specific disciplinary communities can provide useful tools to develop the kind of adaptive and consistent thinking that characterize competence in different domains and how this focus may aid the identification of characteristics common across domains. We use our empirical exploration of adolescents’ development of competence in the domain of history to illustrate the implications of this theoretical framework, to highlight the relations between domain-specific epistemic beliefs and kind of understanding that students built as a result of reading multiple texts, and to suggest what pedagogical practices may have influenced students’ orientations toward knowing in these three history classes.

Zoning Issues and Area of Interest Management in Massively Multiplayer Online Games

Ahmed, Dewan Tanvir; Shirmohammadi, Shervin

Game is a way of entertainment, a means for excitement, fun and socialization. Online games have achieved popularity due to increasing broadband adoption among consumers. Relatively cheap bandwidth Internet connections allow large number of players to play together. Since the introduction of Network Virtual Environment (NVE) in 1980s for military simulation, many interesting applications have been evolved over the past few decades. Massively multiplayer online (role-playing) game, MMOG or MMORPG, is a new genre of online games that has emerged with the introduction of Ultima since 1997. It is a kind of online computer game with the participation of hundreds of thousands of players in a virtual world.

Changes in epistemic frameworks: Random or constrained?

Directory of Open Access Journals (Sweden)

Ananka Loubser

2012-11-01

Full Text Available Since the emergence of a solid anti-positivist approach in the philosophy of science, an important question has been to understand how and why epistemic frameworks change in time, are modified or even substituted. In contemporary philosophy of science three main approaches to framework-change were detected in the humanist tradition:1. In both the pre-theoretical and theoretical domains changes occur according to a rather constrained, predictable or even pre-determined pattern (e.g. Holton.2. Changes occur in a way that is more random or unpredictable and free from constraints (e.g. Kuhn, Feyerabend, Rorty, Lyotard.3. Between these approaches, a middle position can be found, attempting some kind of synthesis (e.g. Popper, Lakatos.Because this situation calls for clarification and systematisation, this article in fact tried to achieve more clarity on how changes in pre-scientific frameworks occur, as well as provided transcendental criticism of the above positions. This article suggested that the above-mentioned positions are not fully satisfactory, as change and constancy are not sufficiently integrated. An alternative model was suggested in which changes in epistemic frameworks occur according to a pattern, neither completely random nor rigidly constrained, which results in change being dynamic but not arbitrary. This alternative model is integral, rather than dialectical and therefore does not correspond to position three. 

Cooperation and control in multiplayer social dilemmas

Science.gov (United States)

Hilbe, Christian; Wu, Bin; Traulsen, Arne; Nowak, Martin A.

2014-01-01

Direct reciprocity and conditional cooperation are important mechanisms to prevent free riding in social dilemmas. However, in large groups, these mechanisms may become ineffective because they require single individuals to have a substantial influence on their peers. However, the recent discovery of zero-determinant strategies in the iterated prisoner’s dilemma suggests that we may have underestimated the degree of control that a single player can exert. Here, we develop a theory for zero-determinant strategies for iterated multiplayer social dilemmas, with any number of involved players. We distinguish several particularly interesting subclasses of strategies: fair strategies ensure that the own payoff matches the average payoff of the group; extortionate strategies allow a player to perform above average; and generous strategies let a player perform below average. We use this theory to describe strategies that sustain cooperation, including generalized variants of Tit-for-Tat and Win-Stay Lose-Shift. Moreover, we explore two models that show how individuals can further enhance their strategic options by coordinating their play with others. Our results highlight the importance of individual control and coordination to succeed in large groups. PMID:25349400

A sampling-based computational strategy for the representation of epistemic uncertainty in model predictions with evidence theory.

Evidence theory provides an alternative to probability theory for the representation of epistemic uncertainty in model predictions that derives from epistemic uncertainty in model inputs, where the descriptor epistemic is used to indicate uncertainty that derives from a lack of knowledge with respect to the appropriate values to use for various inputs to the model. The potential benefit, and hence appeal, of evidence theory is that it allows a less restrictive specification of uncertainty than is possible within the axiomatic structure on which probability theory is based. Unfortunately, the propagation of an evidence theory representation for uncertainty through a model is more computationally demanding than the propagation of a probabilistic representation for uncertainty, with this difficulty constituting a serious obstacle to the use of evidence theory in the representation of uncertainty in predictions obtained from computationally intensive models. This presentation describes and illustrates a sampling-based computational strategy for the representation of epistemic uncertainty in model predictions with evidence theory. Preliminary trials indicate that the presented strategy can be used to propagate uncertainty representations based on evidence theory in analysis situations where naive sampling-based (i.e., unsophisticated Monte Carlo) procedures are impracticable due to computational cost.

SUPPORTING LEARNING THROUGH EPISTEMIC SCAFFOLDS EMBEDDED IN A HIGHLIGHTER TOOL

Directory of Open Access Journals (Sweden)

Jan Erik Dahl

2016-11-01

Full Text Available This article explores the use of epistemic scaffolds embedded in a digital highlighter tool that was used to support students’ readings and discussions of research articles. The use of annotation technologies in education is increasing, and annotations can play a wide variety of epistemic roles; e.g., they can facilitate a deeper level of engagement, support critical thinking, develop cognitive and metacognitive skills and introduce practices that can support knowledge building and independent learning. However, research has shown that the actual tool use often deviates from the underlying knowledge model in the tools. Hence, the situated and mediated nature of these tools is still poorly understood. Research also tends to study the tools as a passed on resource rather than being co-constructed between students and teachers. The researcher argues that approaching these resources as co-constructed can be more productive and can create new spaces for teacher–student dialogues, students’ agency and self-scaffolding.

Where are human subjects in Big Data research? The emerging ethics divide

Directory of Open Access Journals (Sweden)

Jacob Metcalf

2016-06-01

Full Text Available There are growing discontinuities between the research practices of data science and established tools of research ethics regulation. Some of the core commitments of existing research ethics regulations, such as the distinction between research and practice, cannot be cleanly exported from biomedical research to data science research. Such discontinuities have led some data science practitioners and researchers to move toward rejecting ethics regulations outright. These shifts occur at the same time as a proposal for major revisions to the Common Rule—the primary regulation governing human-subjects research in the USA—is under consideration for the first time in decades. We contextualize these revisions in long-running complaints about regulation of social science research and argue data science should be understood as continuous with social sciences in this regard. The proposed regulations are more flexible and scalable to the methods of non-biomedical research, yet problematically largely exclude data science methods from human-subjects regulation, particularly uses of public datasets. The ethical frameworks for Big Data research are highly contested and in flux, and the potential harms of data science research are unpredictable. We examine several contentious cases of research harms in data science, including the 2014 Facebook emotional contagion study and the 2016 use of geographical data techniques to identify the pseudonymous artist Banksy. To address disputes about application of human-subjects research ethics in data science, critical data studies should offer a historically nuanced theory of “data subjectivity” responsive to the epistemic methods, harms and benefits of data science and commerce.

Therapeutic Assessment in Personality Disorders: Toward the Restoration of Epistemic Trust.

Science.gov (United States)

Kamphuis, Jan H; Finn, Stephen E

2018-06-06

Research evidence suggests Therapeutic Assessment positively affects clients with problems in living, including clients with personality disorders, who are typically quite resistant to change. Importantly, this change takes place quickly, in relatively few sessions. This article draws on a relatively new evolutionary-based theory of epistemic trust (ET) and epistemic hypervigilance (EH) as a lens to plausibly explain the efficacy of TA, and especially its influence on PD clients' alliance and motivation for subsequent psychotherapy (Fonagy, Luyten, & Alison, 2015 ). ET is the willingness to take in relevant interpersonally transmited information and it is essential to the immediate success of psychotherapy and its long-term impact. The collaborative, intersubjective framework of TA and many of its specific techniques might be understood as highly relevant to restoring ET in clients, especially those with PD. We close by discussing implications for psychological assessment, psychotherapy, and research.

New Forms of Quantum Value Indefiniteness Suggest That Incompatible Views on Contexts Are Epistemic

Directory of Open Access Journals (Sweden)

Karl Svozil

2018-05-01

Full Text Available Extensions of the Kochen–Specker theorem use quantum logics whose classical interpretation suggests a true-implies-value indefiniteness property. This can be interpreted as an indication that any view of a quantum state beyond a single context is epistemic. A remark by Gleason about the ad hoc construction of probability measures in Hilbert spaces as a result of the Pythagorean property of vector components is interpreted platonically. Unless there is a total match between preparation and measurement contexts, information about the former from the latter is not ontic, but epistemic. This is corroborated by configurations of observables and contexts with a truth-implies-value indefiniteness property.

2017-03-01

Full Text Available Epistemic states of mind, connected with the cognitive activity of a man, are aimed not only at apprehending the world around us, but also at the process of this apprehension. A very important step on this way is an attempt to model these states and processes in terms of formal logics and semantics, irrespective of the language of cognition. The article presents the idea of how formal logical and linguistic modeling of the process of thinking shows the correlation and the interdependence of semantic units connected with mental activities of human brain. The basic notions of the conceptual field of cognition are presented in the article

Hypermentalizing, attachment, and epistemic trust in adolescent BPD: Clinical illustrations.

Science.gov (United States)

Bo, Sune; Sharp, Carla; Fonagy, Peter; Kongerslev, Mickey

2017-04-01

Borderline personality disorder (BPD) has been shown to be a valid and reliable diagnosis in adolescents and associated with a decrease in both general and social functioning. With evidence linking BPD in adolescents to poor prognosis, it is important to develop a better understanding of factors and mechanisms contributing to the development of BPD. This could potentially enhance our knowledge and facilitate the design of novel treatment programs and interventions for this group. In this paper, we outline a theoretical model of BPD in adolescents linking the original mentalization-based theory of BPD, with recent extensions of the theory that focuses on hypermentalizing and epistemic trust. We then provide clinical case vignettes to illustrate this extended theoretical model of BPD. Furthermore, we suggest a treatment approach to BPD in adolescents that focuses on the reduction of hypermentalizing and epistemic mistrust. We conclude with an integration of theory and practice in the final section of the paper and make recommendations for future work in this area.

Background and aims Multiplayer Online Battle Arena (MOBA) games have become the most popular type of video games played worldwide, superseding the playing of Massively Multiplayer Online Role-Playing Games and First-Person Shooter games. However, empirical studies focusing on the use and abuse of MOBA games are still very limited, particularly regarding impulsivity, which is an indicator of addictive states but has not yet been explored in MOBA games. In this context, the objective of the present study is to explore the associations between impulsivity and symptoms of addictive use of MOBA games in a sample of highly involved League of Legends (LoL, currently the most popular MOBA game) gamers. Methods Thirty-six LoL gamers were recruited and completed both experimental (Single Key Impulsivity Paradigm) and self-reported impulsivity assessments (s-UPPS-P Impulsive Behavior Scale, Barratt Impulsiveness Scale), in addition to an assessment of problematic video game use (Problematic Online Gaming Questionnaire). Results Results showed links between impulsivity-related constructs and signs of excessive MOBA game involvement. Findings indicated that impaired ability to postpone rewards in an experimental laboratory task was strongly related to problematic patterns of MOBA game involvement. Although less consistent, several associations were also found between self-reported impulsivity traits and signs of excessive MOBA game involvement. Conclusions Despite these results are preliminary and based upon a small (self-selected) sample, the present study highlights potential psychological factors related to the addictive use of MOBA games.

Background and aims Multiplayer Online Battle Arena (MOBA) games have become the most popular type of video games played worldwide, superseding the playing of Massively Multiplayer Online Role-Playing Games and First-Person Shooter games. However, empirical studies focusing on the use and abuse of MOBA games are still very limited, particularly regarding impulsivity, which is an indicator of addictive states but has not yet been explored in MOBA games. In this context, the objective of the present study is to explore the associations between impulsivity and symptoms of addictive use of MOBA games in a sample of highly involved League of Legends (LoL, currently the most popular MOBA game) gamers.

This case explores a fictitious hospital's use of co-creation to make a decision about redesign of inpatient units as a first step in incorporating stakeholder input into creation of governing policies. We apply a "procedural fairness" framework to reveal that conditions required for an ethical decision about space redesign were not met by using clinician and patient focus groups to obtain stakeholder input. In this article, we identify epistemic injustices resulting from this process that could undermine confidence in leadership decisions. Suggestions are offered for incorporating stakeholder input going forward that address prior shortcomings. The result should be conditions that are perceived as procedurally fair and decisions that engender confidence in institutional leadership. © 2017 American Medical Association. All Rights Reserved.

Epistemic dependence in interdisciplinary groups

DEFF Research Database (Denmark)

Andersen, Hanne; Wagenknecht, Susann

2013-01-01

In interdisciplinary research scientists have to share and integrate knowledge between people and across disciplinary boundaries. An important issue for philosophy of science is to understand how scientists who work in these kinds of environments exchange knowledge and develop new concepts...... and theories across diverging fields. There is a substantial literature within social epistemology that discusses the social aspects of scientific knowledge, but so far few attempts have been made to apply these resources to the analysis of interdisciplinary science. Further, much of the existing work either...... ignores the issue of differences in background knowledge, or it focuses explicitly on conflicting background knowledge. In this paper we provide an analysis of the interplay between epistemic dependence between individual experts with different areas of expertise. We analyze the cooperative activity...

Size matters: the ethical, legal, and social issues surrounding large-scale genetic biobank initiatives

Directory of Open Access Journals (Sweden)

Klaus Lindgaard Hoeyer

2012-04-01

Full Text Available During the past ten years the complex ethical, legal and social issues (ELSI typically surrounding large-scale genetic biobank research initiatives have been intensely debated in academic circles. In many ways genetic epidemiology has undergone a set of changes resembling what in physics has been called a transition into Big Science. This article outlines consequences of this transition and suggests that the change in scale implies challenges to the roles of scientists and public alike. An overview of key issues is presented, and it is argued that biobanks represent not just scientific endeavors with purely epistemic objectives, but also political projects with social implications. As such, they demand clever maneuvering among social interests to succeed.

A noção deontológica de justificação epistêmica

2007-12-01

Full Text Available In this assay we present an introduction to the deontological conception of epistemic justification. We show that the deontological conception of epistemic justification appears of a parallel traced between ethics and epistemology by means of the use of a deontological vocabulary for the evaluation of an epistemic status of our beliefs. We indicate that the deontological conception of epistemic justification finds its origin in a tradition that has John Locke as one of its more illustrious representatives. After this, we explore the relation between justification and normatividade, showing the epistemic judgments are more understood in teleological lines. Finally, we consider what characterizes an epistemic duty.

The Relationships Between Epistemic Beliefs in Biology and Approaches to Learning Biology Among Biology-Major University Students in Taiwan

Science.gov (United States)

Lin, Yi-Chun; Liang, Jyh-Chong; Tsai, Chin-Chung

2012-12-01

The aim of this study was to investigate the relationships between students' epistemic beliefs in biology and their approaches to learning biology. To this end, two instruments, the epistemic beliefs in biology and the approaches to learning biology surveys, were developed and administered to 520 university biology students, respectively. By and large, it was found that the students reflected "mixed" motives in biology learning, while those who had more sophisticated epistemic beliefs tended to employ deep strategies. In addition, the results of paired t tests revealed that the female students were more likely to possess beliefs about biological knowledge residing in external authorities, to believe in a right answer, and to utilize rote learning as a learning strategy. Moreover, compared to juniors and seniors, freshmen and sophomores tended to hold less mature views on all factors of epistemic beliefs regarding biology. Another comparison indicated that theoretical biology students (e.g. students majoring in the Department of Biology) tended to have more mature beliefs in learning biology and more advanced strategies for biology learning than those students studying applied biology (e.g. in the Department of Biotechnology). Stepwise regression analysis, in general, indicated that students who valued the role of experiments and justify epistemic assumptions and knowledge claims based on evidence were more oriented towards having mixed motives and utilizing deep strategies to learn biology. In contrast, students who believed in the certainty of biological knowledge were more likely to adopt rote learning strategies and to aim to qualify in biology.

Do sophisticated epistemic beliefs predict meaningful learning? Findings from a structural equation model of undergraduate biology learning

Lee, Silvia Wen-Yu; Liang, Jyh-Chong; Tsai, Chin-Chung

2016-10-01

This study investigated the relationships among college students' epistemic beliefs in biology (EBB), conceptions of learning biology (COLB), and strategies of learning biology (SLB). EBB includes four dimensions, namely 'multiple-source,' 'uncertainty,' 'development,' and 'justification.' COLB is further divided into 'constructivist' and 'reproductive' conceptions, while SLB represents deep strategies and surface learning strategies. Questionnaire responses were gathered from 303 college students. The results of the confirmatory factor analysis and structural equation modelling showed acceptable model fits. Mediation testing further revealed two paths with complete mediation. In sum, students' epistemic beliefs of 'uncertainty' and 'justification' in biology were statistically significant in explaining the constructivist and reproductive COLB, respectively; and 'uncertainty' was statistically significant in explaining the deep SLB as well. The results of mediation testing further revealed that 'uncertainty' predicted surface strategies through the mediation of 'reproductive' conceptions; and the relationship between 'justification' and deep strategies was mediated by 'constructivist' COLB. This study provides evidence for the essential roles some epistemic beliefs play in predicting students' learning.

Epistemic uncertainties when estimating component failure rate

International Nuclear Information System (INIS)

Jordan Cizelj, R.; Mavko, B.; Kljenak, I.

2000-01-01

A method for specific estimation of a component failure rate, based on specific quantitative and qualitative data other than component failures, was developed and is described in the proposed paper. The basis of the method is the Bayesian updating procedure. A prior distribution is selected from a generic database, whereas likelihood is built using fuzzy logic theory. With the proposed method, the component failure rate estimation is based on a much larger quantity of information compared to the presently used classical methods. Consequently, epistemic uncertainties, which are caused by lack of knowledge about a component or phenomenon are reduced. (author)

Altruism in multiplayer snowdrift games with threshold and punishment

Science.gov (United States)

Zhang, Chunyan; Liu, Zhongxin; Sun, Qinglin; Chen, Zengqiang

2015-09-01

The puzzle of cooperation attracts broader concerns of the scientific community nowadays. Here we adopt an extra mechanism of punishment in the framework of a threshold multiple-player snowdrift game employed as the scenario for the cooperation problem. Two scenarios are considered: defectors will suffer punishment regardless of the game results, and defectors will incur punishment only when the game fails. We show by analysis that given this assumption, punishing free riders can significantly influence the evolution outcomes, and the results are driven by the specific components of the punishing rule. Particularly, punishing defectors always, not only when the game fails, can be more effective for maintaining public cooperation in multi-player systems. Intriguingly larger thresholds of the game provide a more favorable scenario for the coexistence of the cooperators and defectors under a broad value range of parameters. Further, cooperators are best supported by the large punishment on defectors, and then dominate and stabilize in the population, under the premise that defectors always incur punishment regardless of whether the game ends successfully or not.

This study investigates user behaviour in massively multiplayer online games from the perspective of their intentions to engage in real money trading. Players who engage in real money trading purchase resources instead of spending time to acquire them in the game. This behaviour influences not just...... a set of behavioural determinants grounded in empirical research on online games. The study’s findings indicate that a player’s social status and the disinhibiting effects of online play are positive influences on players’ intentions to engage in real money trading, while perceived fairness, anticipated...... regret and uncertainty about the seller’s behaviour are negative influences. Interestingly, neither the perceived enjoyment nor the potential punishments influence intentions...

Connectomes as constitutively epistemic objects: Critical perspectives on modeling in current neuroanatomy.

Science.gov (United States)

Haueis, Philipp; Slaby, Jan

2017-01-01

The term "connectome" is commonly taken to describe a complete map of neural connections in a nervous system of a given species. This chapter provides a critical perspective on the role of connectomes in neuroscientific practice and asks how the connectomic approach fits into a larger context in which network thinking permeates technology, infrastructure, social life, and the economy. In the first part of this chapter, we argue that, seen from the perspective of ongoing research, the notion of connectomes as "complete descriptions" is misguided. Our argument combines Rachel Ankeny's analysis of neuroanatomical wiring diagrams as "descriptive models" with Hans-Jörg Rheinberger's notion of "epistemic objects," i.e., targets of research that are still partially unknown. Combining these aspects we conclude that connectomes are constitutively epistemic objects: there just is no way to turn them into permanent and complete technical standards because the possibilities to map connection properties under different modeling assumptions are potentially inexhaustible. In the second part of the chapter, we use this understanding of connectomes as constitutively epistemic objects in order to critically assess the historical and political dimensions of current neuroscientific research. We argue that connectomics shows how the notion of the "brain as a network" has become the dominant metaphor of contemporary brain research. We further point out that this metaphor shares (potentially problematic) affinities to the form of contemporary "network societies." We close by pointing out how the relation between connectomes and networks in society could be used in a more fruitful manner. © 2017 Elsevier B.V. All rights reserved.

Pre-service teachers’ perceived value of general pedagogical knowledge for practice: Relations with epistemic beliefs and source beliefs

Rosman, Tom; Rueß, Julia; Syring, Marcus; Schneider, Jürgen

2017-01-01

Pre-service teachers tend to devalue general pedagogical knowledge (GPK) as a valid source for deriving successful teaching practices. The present study investigated beliefs about knowledge sources and epistemic beliefs as predictors for students’ perceived value of GPK. Three pre-registered hypotheses were tested. We expected beliefs that GPK originates from scientific sources to entail a devaluation of GPK (Hypothesis 1). Concerning epistemic beliefs, we expected absolute beliefs to positively, and multiplistic beliefs to negatively predict pre-service teachers’ perceived practical value of GPK (Hypothesis 2). Finally, we expected relationships between epistemic beliefs and pre-service teachers’ perceived practical value of GPK to be confounded by epistemic trustworthiness, perceived topic-specific consistency and topic-specific familiarity (Hypothesis 3). In a study using a split plot design, 365 pre-service teachers were presented with four texts on different educational research topics. For each topic, three text versions were constructed. Even though they were invariant in content, these versions varied in a way that the results were allegedly generated by a practitioner, an expert or by means of a scientific study. Unexpectedly, results showed that research findings allegedly generated by means of a scientific study were associated with a higher perceived value of (topic-specific) GPK for practice (Hypothesis 1). As expected, the perceived value of GPK for practice was predicted by topic-specific multiplism and domain-specific absolutism (Hypothesis 2). These predictive effects were confounded by expertise evaluations of the source and the consistency of prior beliefs with the presented research results (Hypothesis 3). In summary, our results suggest that source beliefs might not be responsible for the devaluation of GPK, but that beliefs on the nature and structure of GPK (i.e., epistemic beliefs) might play an even more important role in this respect

What is Proof of Concept Research and how does it Generate Epistemic and Ethical Categories for Future Scientific Practice?

Science.gov (United States)

Kendig, Catherine Elizabeth

2016-06-01

"Proof of concept" is a phrase frequently used in descriptions of research sought in program announcements, in experimental studies, and in the marketing of new technologies. It is often coupled with either a short definition or none at all, its meaning assumed to be fully understood. This is problematic. As a phrase with potential implications for research and technology, its assumed meaning requires some analysis to avoid it becoming a descriptive category that refers to all things scientifically exciting. I provide a short analysis of proof of concept research and offer an example of it within synthetic biology. I suggest that not only are there activities that circumscribe new epistemological categories but there are also associated normative ethical categories or principles linked to the research. I examine these and provide an outline for an alternative ethical account to describe these activities that I refer to as "extended agency ethics". This view is used to explain how the type of research described as proof of concept also provides an attendant proof of principle that is the result of decision-making that extends across practitioners, their tools, techniques, and the problem solving activities of other research groups.

Aleatoric and epistemic uncertainties in sampling based nuclear data uncertainty and sensitivity analyses

International Nuclear Information System (INIS)

Zwermann, W.; Krzykacz-Hausmann, B.; Gallner, L.; Klein, M.; Pautz, A.; Velkov, K.

2012-01-01

Sampling based uncertainty and sensitivity analyses due to epistemic input uncertainties, i.e. to an incomplete knowledge of uncertain input parameters, can be performed with arbitrary application programs to solve the physical problem under consideration. For the description of steady-state particle transport, direct simulations of the microscopic processes with Monte Carlo codes are often used. This introduces an additional source of uncertainty, the aleatoric sampling uncertainty, which is due to the randomness of the simulation process performed by sampling, and which adds to the total combined output sampling uncertainty. So far, this aleatoric part of uncertainty is minimized by running a sufficiently large number of Monte Carlo histories for each sample calculation, thus making its impact negligible as compared to the impact from sampling the epistemic uncertainties. Obviously, this process may cause high computational costs. The present paper shows that in many applications reliable epistemic uncertainty results can also be obtained with substantially lower computational effort by performing and analyzing two appropriately generated series of samples with much smaller number of Monte Carlo histories each. The method is applied along with the nuclear data uncertainty and sensitivity code package XSUSA in combination with the Monte Carlo transport code KENO-Va to various critical assemblies and a full scale reactor calculation. It is shown that the proposed method yields output uncertainties and sensitivities equivalent to the traditional approach, with a high reduction of computing time by factors of the magnitude of 100.

Epistemic injustice in dementia and autism patient organizations: An empirical analysis.

Science.gov (United States)

Jongsma, Karin; Spaeth, Elisabeth; Schicktanz, Silke

2017-01-01

Patient organizations (POs) represent patient collectives in health care policy. The inclusion of people with a 'neuro-psychiatric' condition poses a particular challenge for the organizational processes and political representation of such collectives. In recent years, new POs (POs of) have been established in the field of autism spectrum disorder and dementia that advocate a different agenda and have a different organizational structure than traditional POs (POs for). The divide between these two types of POs indicates a different standpoint with regard to who should be included on an organizational level, which voices are accepted and who should represent these voices on the political level. The inclusion and exclusion of voices needs to be normatively justified in order to be regarded legitimate representation of such a collective. With the help of Miranda Fricker's theory of epistemic injustice, we scrutinize whether and, if so, which types of epistemic injustices (wrongdoings to a person as a knower) can be found within POs' practices and the political field in which they operate, by analyzing 37 interviews with PO representatives, their members and policy makers. Our in-depth analysis indicates that persistent stereotypes hamper the inclusion of affected members both within POs and on the health political level. Being affected causes distrust in having the 'capacity to know' in a two-fold way; it is assumed that those who can represent themselves are "not affected enough" to present valuable insights into the condition and those who have difficulties to express themselves due to their condition are excluded because of their affectedness. We conclude that our analysis of the epistemic practices of POs serves as a good starting point to address these shortcomings from a theoretical and practical perspective and offers a valuable starting point for bioethics to understand unjust structures in the health political context.

An engineering paradigm in the biomedical sciences: Knowledge as epistemic tool.

Science.gov (United States)

Boon, Mieke

2017-10-01

In order to deal with the complexity of biological systems and attempts to generate applicable results, current biomedical sciences are adopting concepts and methods from the engineering sciences. Philosophers of science have interpreted this as the emergence of an engineering paradigm, in particular in systems biology and synthetic biology. This article aims at the articulation of the supposed engineering paradigm by contrast with the physics paradigm that supported the rise of biochemistry and molecular biology. This articulation starts from Kuhn's notion of a disciplinary matrix, which indicates what constitutes a paradigm. It is argued that the core of the physics paradigm is its metaphysical and ontological presuppositions, whereas the core of the engineering paradigm is the epistemic aim of producing useful knowledge for solving problems external to the scientific practice. Therefore, the two paradigms involve distinct notions of knowledge. Whereas the physics paradigm entails a representational notion of knowledge, the engineering paradigm involves the notion of 'knowledge as epistemic tool'. Copyright © 2017 Elsevier Ltd.

Geralt of Poland: The Witcher 3 Between Epistemic Disobedience and Imperial Nostalgia

Directory of Open Access Journals (Sweden)

Tomasz Z. Majkowski

2018-01-01

Full Text Available This article is a reading of 'The Witcher 3' in relation to postcolonial approaches to Polish culture. It departs from an analysis of an online debate on racial representation in the game as a possible act of epistemic disobedience, and moves on to a consideration of three narrative aspects of the game itself: its representation of political struggle, the ideological stance of the protagonist, and ethnic inspirations in worldbuilding. By referring those three issues to postcolonial analyses of Polish culture, as well as Walter D. Mignolo’s concept of decolonization through epistemic disobedience, this article aims to demonstrate paradoxical qualities of the game, which tries to simultaneously distance itself from the established, West-oriented ways of knowledge production and gain recognition as an artifact of modern Western pop culture. Moreover, it employs the tradition of Polish Romanticism to establish itself as a bridge between Slavdom and Western culture, and strengthen the colonial idea of Poland being the proper ruler over Slavs.

Epistemic characteristics of Mapuche educational methods

Daniel Quilaqueo Rapimán

2016-01-01

Full Text Available This article presents the main epistemic characteristics of the educational methods used in Mapuche family education in communities in the Araucanía region, in Chile. The concept of epistemology is considered with regards to the production of practical, technical, symbolical and spiritual knowledge, as an epistemological critique of the monocultural nature of the school curriculum. The methodology used is qualitative research, based on Grounded Theory; the results shed light on the educational methods used in the learning and teaching of content relating to individuals and society, the setting in time and place, and spatial awareness. It is concluded that this kind of education is organized considering distinctive methods formulated on the basis of the rationale of Mapuche educational knowledge.

Epistemic and aleatory uncertainties in integrated deterministic and probabilistic safety assessment: Tradeoff between accuracy and accident simulations

International Nuclear Information System (INIS)

Karanki, D.R.; Rahman, S.; Dang, V.N.; Zerkak, O.

2017-01-01

The coupling of plant simulation models and stochastic models representing failure events in Dynamic Event Trees (DET) is a framework used to model the dynamic interactions among physical processes, equipment failures, and operator responses. The integration of physical and stochastic models may additionally enhance the treatment of uncertainties. Probabilistic Safety Assessments as currently implemented propagate the (epistemic) uncertainties in failure probabilities, rates, and frequencies; while the uncertainties in the physical model (parameters) are not propagated. The coupling of deterministic (physical) and probabilistic models in integrated simulations such as DET allows both types of uncertainties to be considered. However, integrated accident simulations with epistemic uncertainties will challenge even today's high performance computing infrastructure, especially for simulations of inherently complex nuclear or chemical plants. Conversely, intentionally limiting computations for practical reasons would compromise accuracy of results. This work investigates how to tradeoff accuracy and computations to quantify risk in light of both uncertainties and accident dynamics. A simple depleting tank problem that can be solved analytically is considered to examine the adequacy of a discrete DET approach. The results show that optimal allocation of computational resources between epistemic and aleatory calculations by means of convergence studies ensures accuracy within a limited budget. - Highlights: • Accident simulations considering uncertainties require intensive computations. • Tradeoff between accuracy and accident simulations is a challenge. • Optimal allocation between epistemic & aleatory computations ensures the tradeoff. • Online convergence gives an early indication of computational requirements. • Uncertainty propagation in DDET is examined on a tank problem solved analytically.

Saccadic (rapid) eye movements are primary means by which humans and non-human primates sample visual information. However, while saccadic decisions are intensively investigated in instrumental contexts where saccades guide subsequent actions, it is largely unknown how they may be influenced by curiosity - the intrinsic desire to learn. While saccades are sensitive to visual novelty and visual surprise, no study has examined their relation to epistemic curiosity - interest in symbolic, semantic information. To investigate this question, we tracked the eye movements of human observers while they read trivia questions and, after a brief delay, were visually given the answer. We show that higher curiosity was associated with earlier anticipatory orienting of gaze toward the answer location without changes in other metrics of saccades or fixations, and that these influences were distinct from those produced by variations in confidence and surprise. Across subjects, the enhancement of anticipatory gaze was correlated with measures of trait curiosity from personality questionnaires. Finally, a machine learning algorithm could predict curiosity in a cross-subject manner, relying primarily on statistical features of the gaze position before the answer onset and independently of covariations in confidence or surprise, suggesting potential practical applications for educational technologies, recommender systems and research in cognitive sciences. With this article, we provide full access to the annotated database allowing readers to reproduce the results. Epistemic curiosity produces specific effects on oculomotor anticipation that can be used to read out curiosity states. Copyright © 2015 The Authors. Published by Elsevier Ltd.. All rights reserved.

Forensic culture as epistemic culture: the sociology of forensic science.

Science.gov (United States)

Cole, Simon A

2013-03-01

This paper explores whether we can interpret the notion of 'forensic culture' as something akin to what Knorr-Cetina called an 'epistemic culture'. Can we speak of a 'forensic culture', and, if so, how is it similar to, or different from, other epistemic cultures that exist in what is conventionally called 'science'? This question has important policy implications given the National Academy Science's (NAS) recent identification of 'culture' as one of the problems at the root of what it identified as 'serious deficiencies' in U.S. forensic science and 'scientific culture' as an antidote to those problems. Finding the NAS's characterisation of 'scientific culture' overly general and naïve, this paper offers a preliminary exploration of what might be called a 'forensic culture'. Specifically, the paper explores the way in which few of the empirical findings accumulated by sociologists of science about research science seem to apply to forensic science. Instead, forensic science seems to have developed a distinct culture for which a sociological analysis will require new explanatory tools. Faithful sociological analysis of 'forensic culture' will be a necessary prerequisite for the kind of culture change prescribed by external reformist bodies like the NAS. Copyright © 2012.

Invention through bricolage: epistemic engineering in scientific communities

Directory of Open Access Journals (Sweden)

Alexander James Gillett

2018-03-01

Full Text Available It is widely recognised that knowledge accumulation is an important aspect of scientific communities. In this essay, drawing on a range of material from theoretical biology and behavioural science, I discuss a particular aspect of the intergenerational nature of human communities – “virtual collaboration” (Tomasello 1999 – and how it can lead to epistemic progress without any explicit intentional creativity (Henrich 2016. My aim in this paper is to make this work relevant to theorists working on the social structures of science so that these processes can be utilised and optimised in scientific communities.

Determinism and Underdetermination in Genetics: Implications for Students' Engagement in Argumentation and Epistemic Practices

Science.gov (United States)

Jiménez-Aleixandre, María Pilar

2014-02-01

In the last two decades science studies and science education research have shifted from an interest in products (of science or of learning), to an interest in processes and practices. The focus of this paper is on students' engagement in epistemic practices (Kelly in Teaching scientific inquiry: Recommendations for research and implementation. Sense Publishers, Rotterdam, pp 99-117, 2008), or on their practical epistemologies (Wickman in Sci Educ 88(3):325-344, 2004). In order to support these practices in genetics classrooms we need to take into account domain-specific features of the epistemology of genetics, in particular issues about determinism and underdetermination. I suggest that certain difficulties may be related to the specific nature of causality in genetics, and in particular to the correspondence between a given set of factors and a range of potential effects, rather than a single one. The paper seeks to bring together recent developments in the epistemology of biology and of genetics, on the one hand, with science education approaches about epistemic practices, on the other. The implications of these perspectives for current challenges in learning genetics are examined, focusing on students' engagement in epistemic practices, as argumentation, understood as using evidence to evaluate knowledge claims. Engaging in argumentation in genetics classrooms is intertwined with practices such as using genetics models to build explanations, or framing genetics issues in their social context. These challenges are illustrated with studies making part of our research program in the USC.

Verbal markers of epistemic modality and their role in the development of communicative competences

Barbara Pihler Ciglič

2014-12-01

Full Text Available Modality in language, one of the characteristic phenomena of the process of communication, has to do with, in the broad sense, the mindset that the speaker indicates in his words while describing, questioning, or wanting to draw attention to what he is saying. Traditionally there is a tendency to gather, under the broad label of linguistic modality, a variety of different forms: verbal mode, auxiliary verbs, certain adverbs and particles, intonation, etc. The aim of this study is to analyze the Spanish verbal markers and their possibilities to express epistemic modality, which is defined as the linguistic expression of the degree of commitment that the speaker assumes about the factuality of his statement (Lyons 1977, Palmer 1986. The study focuses, first, on modal verbal periphrases and some of the tenses which can indicate the epistemic modality and/or evidentiality in certain contexts through the so-called »quotative« or »polyphonic« uses. The second part of this study consists of an analysis of the systematization of these resources in six selected manuals of Spanish as a Second Language (SSL; levels B1, B2 and C1 according to CEFR, with special attention to its contribution to the development of communicative competences (linguistic, sociolinguistic and pragmatic competence, again according to CEFR. We believe that the explicit study of epistemic modality in the SSL classroom effectively contributes to a good command of Spanish, and therefore deserves more attention.

Secondary School Students' Epistemic Insight into the Relationships Between Science and Religion—A Preliminary Enquiry

Science.gov (United States)

Billingsley, Berry; Taber, Keith; Riga, Fran; Newdick, Helen

2013-08-01

A number of previous studies have shown that there is a widespread view among young people that science and religion are opposed. In this paper, we suggest that it requires a significant level of what can be termed "epistemic insight" to access the idea that some people see science and religion as compatible while others do not. To explore this further, we draw on previous work to devise a methodology to discover students' thinking about apparent contradictions between scientific and religious explanations of the origins of the universe. In our discussion of the findings, we highlight that students' epistemic insight in this context does seem in many cases to be limited and we outline some of the issues emerging from the study that seem to boost or limit students' progress in this area.

Epistemic uncertainties and natural hazard risk assessment - Part 1: A review of the issues

Uncertainties in natural hazard risk assessment are generally dominated by the sources arising from lack of knowledge or understanding of the processes involved. There is a lack of knowledge about frequencies, process representations, parameters, present and future boundary conditions, consequences and impacts, and the meaning of observations in evaluating simulation models. These are the epistemic uncertainties that can be difficult to constrain, especially in terms of event or scenario probabilities, even as elicited probabilities rationalized on the basis of expert judgements. This paper reviews the issues raised by trying to quantify the effects of epistemic uncertainties. Such scientific uncertainties might have significant influence on decisions that are made for risk management, so it is important to communicate the meaning of an uncertainty estimate and to provide an audit trail of the assumptions on which it is based. Some suggestions for good practice in doing so are made.

Meaningful main effects or intriguing interactions? Examining the influences of epistemic beliefs and knowledge representations on cognitive processing and conceptual change when learning physics

Science.gov (United States)

Franco, Gina M.

The purpose of this study was to investigate the role of epistemic beliefs and knowledge representations in cognitive and metacognitive processing and conceptual change when learning about physics concepts through text. Specifically, I manipulated the representation of physics concepts in texts about Newtonian mechanics and explored how these texts interacted with individuals' epistemic beliefs to facilitate or constrain learning. In accordance with definitions from Royce's (1983) framework of psychological epistemology, texts were developed to present Newtonian concepts in either a rational or a metaphorical format. Seventy-five undergraduate students completed questionnaires designed to measure their epistemic beliefs and their misconceptions about Newton's laws of motion. Participants then read the first of two instructional texts (in either a rational or metaphorical format), and were asked to think aloud while reading. After reading the text, participants completed a recall task and a post-test of selected items regarding Newtonian concepts. These steps were repeated with a second instructional text (in either a rational or metaphorical format, depending on which format was assigned previously). Participants' think-aloud sessions were audio-recorded, transcribed, and then blindly coded, and their recalls were scored for total number of correctly recalled ideas from the text. Changes in misconceptions were analyzed by examining changes in participants' responses to selected questions about Newtonian concepts from pretest to posttest. Results revealed that when individuals' epistemic beliefs were congruent with the knowledge representations in their assigned texts, they performed better on both online measures of learning (e.g., use of processing strategies) and offline products of learning (e.g., text recall, changes in misconceptions) than when their epistemic beliefs were incongruent with the knowledge representations. These results have implications for how

Complexity as AN Epistemic Revolution: Considerations on the New Science in the Context of Western Intellectual History

Science.gov (United States)

Popolo, Damian

The paper will seek to present a genesis of complexity in European philosophical thought. Following the works of Gleick and Hobsbawn it is possible to discern the emergence of complexity's ethos in the `age of revolutions'. Gleick, for example, has noted the influence of natural philosophy on the first precursors of chaos theory. Natural philosophy itself was deeply anchored in German romanticism. The paper will thus seek to present, following Foucault, an `Archaeology of Complexity' which considers Foucault's definition of epistemes as evolving modes of thought. In particular, the paper will seek to use Foucault's description of the modern episteme in order to detect the novelty inherent within the ethos of Complexity.

Player guild dynamics and evolution in massively multiplayer online games.

Chen, Chien-Hsun; Sun, Chuen-Tsai; Hsieh, Jilung

2008-06-01

In the latest versions of massively multiplayer online games (MMOGs), developers have purposefully made guilds part of game environments. Guilds represent a powerful method for giving players a sense of online community, but there is little quantitative data on guild dynamics. To address this topic, we took advantage of a feature found in one of today's most popular MMOGs (World of Warcraft) to collect in-game data: user interfaces that players can modify and refine. In addition to collecting data on in-game player activities, we used this feature to observe and investigate how players join and leave guilds. Data were analyzed for the purpose of identifying factors that propel game-world guild dynamics and evolution. After collecting data for 641,805 avatars on 62 Taiwanese World of Warcraft game servers between February 10 and April 10, 2006, we created five guild type categories (small, large, elite, newbie, and unstable) that have different meanings in terms of in-game group dynamics. By viewing players as the most important resource affecting guild life cycles, it is possible to analyze game worlds as ecosystems consisting of evolving guilds and to study how guild life cycles reflect game world characteristics.

[Applying Ethics, Placating Ethics, or Applying ourselves to Ethics? A Critical View of Environmental Ethics as Applied Ethics].

Science.gov (United States)

Serani Merlo, Alejandro

2016-01-01

There is actually a pervasive tendency to consider environmental ethics and bioethics as specific cases pertaining to a supposed kind of ″applied ethics″. Application can be understood in two different meanings: a concrete sense, as in technical applications, and a psychological meaning, as when we mentally apply ourselves to a task. Ethics has been always thought as a practical knowledge, in a ″praxical″ sense and not in a ″poietic″ one. Ethics has to do with ″ends″ not with ″means″; in this sense ethics is ″useless″. Since ethics has to do with the ultimate meaning of things, ethical choices give meaning to all practical activities. In that sense ethics instead of being useless must be considered as ″over-useful″ (Maritain). Nowadays politics tend to instrumentalize ethics in order to political objectives. The consequence has been the reconceptualization of specific ethics as applied ethics. Environmental ethics and bioethics are then submitted to politics following the logic of technical applications. Environmental ethics and bioethics considered as applied ethics are at risk to becoming not only useless, but also meaningless.

How successful are mutants in multiplayer games with fluctuating environments? Sojourn times, fixation and optimal switching

Science.gov (United States)

Baron, Joseph W.; Galla, Tobias

2018-03-01

Using a stochastic model, we investigate the probability of fixation, and the average time taken to achieve fixation, of a mutant in a population of wild-types. We do this in a context where the environment in which the competition takes place is subject to stochastic change. Our model takes into account interactions which can involve multiple participants. That is, the participants take part in multiplayer games. We find that under certain circumstances, there are environmental switching dynamics which minimize the time that it takes for the mutants to fixate. To analyse the dynamics more closely, we develop a method by which to calculate the sojourn times for general birth-death processes in fluctuating environments.

Constructive Epistemic Modeling: A Hierarchical Bayesian Model Averaging Method

Science.gov (United States)

Tsai, F. T. C.; Elshall, A. S.

2014-12-01

Constructive epistemic modeling is the idea that our understanding of a natural system through a scientific model is a mental construct that continually develops through learning about and from the model. Using the hierarchical Bayesian model averaging (HBMA) method [1], this study shows that segregating different uncertain model components through a BMA tree of posterior model probabilities, model prediction, within-model variance, between-model variance and total model variance serves as a learning tool [2]. First, the BMA tree of posterior model probabilities permits the comparative evaluation of the candidate propositions of each uncertain model component. Second, systemic model dissection is imperative for understanding the individual contribution of each uncertain model component to the model prediction and variance. Third, the hierarchical representation of the between-model variance facilitates the prioritization of the contribution of each uncertain model component to the overall model uncertainty. We illustrate these concepts using the groundwater modeling of a siliciclastic aquifer-fault system. The sources of uncertainty considered are from geological architecture, formation dip, boundary conditions and model parameters. The study shows that the HBMA analysis helps in advancing knowledge about the model rather than forcing the model to fit a particularly understanding or merely averaging several candidate models.

Reliability assessment of complex electromechanical systems under epistemic uncertainty

International Nuclear Information System (INIS)

Mi, Jinhua; Li, Yan-Feng; Yang, Yuan-Jian; Peng, Weiwen; Huang, Hong-Zhong

2016-01-01

The appearance of macro-engineering and mega-project have led to the increasing complexity of modern electromechanical systems (EMSs). The complexity of the system structure and failure mechanism makes it more difficult for reliability assessment of these systems. Uncertainty, dynamic and nonlinearity characteristics always exist in engineering systems due to the complexity introduced by the changing environments, lack of data and random interference. This paper presents a comprehensive study on the reliability assessment of complex systems. In view of the dynamic characteristics within the system, it makes use of the advantages of the dynamic fault tree (DFT) for characterizing system behaviors. The lifetime of system units can be expressed as bounded closed intervals by incorporating field failures, test data and design expertize. Then the coefficient of variation (COV) method is employed to estimate the parameters of life distributions. An extended probability-box (P-Box) is proposed to convey the present of epistemic uncertainty induced by the incomplete information about the data. By mapping the DFT into an equivalent Bayesian network (BN), relevant reliability parameters and indexes have been calculated. Furthermore, the Monte Carlo (MC) simulation method is utilized to compute the DFT model with consideration of system replacement policy. The results show that this integrated approach is more flexible and effective for assessing the reliability of complex dynamic systems. - Highlights: • A comprehensive study on the reliability assessment of complex system is presented. • An extended probability-box is proposed to convey the present of epistemic uncertainty. • The dynamic fault tree model is built. • Bayesian network and Monte Carlo simulation methods are used. • The reliability assessment of a complex electromechanical system is performed.

This paper investigates the role of epistemic belief in affecting Internet users' decision to share online health rumors. To delve deeper, it examines how the characteristics of rumors-true or false, textual or pictorial, dread or wish-shape the decision-making among epistemologically naïve and robust users separately. An experiment was conducted. Responses were obtained from 110 participants, who were exposed to eight rumors. This yielded 880 cases (110 participants×8 rumors) for statistical analyses. Epistemologically naive participants were more likely to share online health rumors than epistemologically robust individuals. Epistemologically robust participants were more likely to share textual rumors than pictorial ones. However, there were no differences between true and false rumors or between dread and wish rumors for either epistemologically naive or robust participants. This paper contributes to the understanding of users' health information sharing behavior. It encourages users to cultivate robust epistemic belief in order to improve their online health information processing skills. Copyright © 2017. Published by Elsevier B.V.

Jiang, Zhi-Qiang; Ren, Fei; Gu, Gao-Feng; Tan, Qun-Zhao; Zhou, Wei-Xing

2010-02-01

Massive multiplayer online role-playing games (MMORPGs) have been very popular in the past few years. The profit of an MMORPG company is proportional to how many users registered, and the instant number of online avatars is a key factor to assess how popular an MMORPG is. We use the online-offline logs on an MMORPG server to reconstruct the instant number of online avatars per second and investigate its statistical properties. We find that the online avatar number exhibits one-day periodic behavior and clear intraday pattern, the fluctuation distribution of the online avatar numbers has a leptokurtic non-Gaussian shape with power-law tails, and the increments of online avatar numbers after removing the intraday pattern are uncorrelated and the associated absolute values have long-term correlation. In addition, both time series exhibit multifractal nature.

Subjectivity and Reflexivity in the Social Sciences: Epistemic Windows and Methodical Consequences

Directory of Open Access Journals (Sweden)

Franz Breuer

2003-05-01

Full Text Available We sketch four basic epistemological assumptions that imply a constructionist orientation to knowledge including (a perspectivity, positionality; (b horizonality, dynamic observer position; (c the structuring of knowledge through instruments of knowledge production; and (d interactivity and interventionist nature of research. Although social scientists often adopt a constructionist epistemology to frame their research object, the methodological consequences of such an epistemology for the production of social scientific knowledge are not normally drawn. Instead of dealing with the four assumptions as a productive epistemic window, many researchers exhibit a defensive tendency and continue the quest for objectivity in their own writing. We propose a different methodological position conceptualized in the dialectic of the always embodied, individual, and social researcher-in-interaction. Beginning with the concept of a decentered (self- observation we develop the idea of the reflexive nature that relates the epistemic subject and object. We propose a way systematizing methodological considerations and procedures that follows the research process, beginning with the identification of a research topic to the final presentation of the results. The contributions to the two present FQS volumes on "Subjectivity and Reflexivity in Qualitative Research" provide answers and possible solutions to the questions and problems raised in this introduction.

Effect of Epistemic Uncertainty Modeling Approach on Decision-Making: Example using Equipment Performance Indicator

Energy Technology Data Exchange (ETDEWEB)

Dana Kelly; Robert Youngblood

2012-06-01

Quantitative risk assessments are an integral part of risk-informed regulation of current and future nuclear plants in the U.S. The Bayesian approach to uncertainty, in which both stochastic and epistemic uncertainties are represented with precise probability distributions, is the standard approach to modeling uncertainties in such quantitative risk assessments. However, there are long-standing criticisms of the Bayesian approach to epistemic uncertainty from many perspectives, and a number of alternative approaches have been proposed. Among these alternatives, the most promising (and most rapidly developing) would appear to be the concept of imprecise probability. In this paper, we employ a performance indicator example to focus the discussion. We first give a short overview of the traditional Bayesian paradigm and review some its controversial aspects, for example, issues with so-called noninformative prior distributions. We then discuss how the imprecise probability approach treats these issues and compare it with two other approaches: sensitivity analysis and hierarchical Bayes modeling. We conclude with some practical implications for risk-informed decision making.

Individual differences in preference for epistemic versus teleologic strategies of deliberate self-persuasion.

People are often dissatisfied with their attitudes (e.g., liking their jobs too little or junk food too much) and would like to evaluate differently. On the basis of theory and research, a scale was developed to measure individual differences in preference for 2 types of cognitive tactics (epistemic or teleologic [E or T]) that people use when they try to change their own attitudes (Maio & Thomas, 2007). For each of 3 attitude objects (my life, a romantic partner, Arabs), the scale items loaded on the 2 intended factors, and E - T scale scores were significantly correlated across the 3 attitude objects (Study 1). Scale scores also displayed satisfactory internal and test-retest reliability and discriminant validity (Study 2). In addition, E - T scores (i.e., mean preference for epistemic vs. teleologic tactics) displayed satisfactory predictive and construct validity by predicting the extent to which individuals would recall negative attributes of their lives (Study 3) and of going to a counseling center (Study 4) after a session of deliberate self-persuasion. The discussion centers on theoretical and practical applications of the new scale. 2014 APA

Owing to the increase in unprecedented accidents with new root causes in almost all operational areas, the importance of risk management has dramatically risen. Risk assessment, one of the most significant aspects of risk management, has a substantial impact on the system-safety level of organizations, industries, and operations. If the causes of all kinds of failure and the interactions between them are considered, effective risk assessment can be highly accurate. A combination of traditional risk assessment approaches and modern scientific probability methods can help in realizing better quantitative risk assessment methods. Most researchers face the problem of minimal field data with respect to the probability and frequency of each failure. Because of this limitation in the availability of epistemic knowledge, it is important to conduct epistemic estimations by applying the Bayesian theory for identifying plausible outcomes. In this paper, we propose an algorithm and demonstrate its application in a case study for a light-weight lifting operation in the Persian Gulf of Iran. First, we identify potential accident scenarios and present them in an event tree format. Next, excluding human error, we use the event tree to roughly estimate the prior probability of other hazard-promoting factors using a minimal amount of field data. We then use the Success Likelihood Index Method (SLIM) to calculate the probability of human error. On the basis of the proposed event tree, we use the Bayesian network of the provided scenarios to compensate for the lack of data. Finally, we determine the resulting probability of each event based on its evidence in the epistemic estimation format by building on two Bayesian network types: the probability of hazard promotion factors and the Bayesian theory. The study results indicate that despite the lack of available information on the operation of floating objects, a satisfactory result can be achieved using epistemic data.

On the epistemic view of quantum states

International Nuclear Information System (INIS)

Skotiniotis, Michael; Roy, Aidan; Sanders, Barry C.

2008-01-01

We investigate the strengths and limitations of the Spekkens toy model, which is a local hidden variable model that replicates many important properties of quantum dynamics. First, we present a set of five axioms that fully encapsulate Spekkens' toy model. We then test whether these axioms can be extended to capture more quantum phenomena by allowing operations on epistemic as well as ontic states. We discover that the resulting group of operations is isomorphic to the projective extended Clifford group for two qubits. This larger group of operations results in a physically unreasonable model; consequently, we claim that a relaxed definition of valid operations in Spekkens' toy model cannot produce an equivalence with the Clifford group for two qubits. However, the new operations do serve as tests for correlation in a two toy bit model, analogous to the well known Horodecki criterion for the separability of quantum states

Epistemic Dependence and the EU Seal Ban Debate

Directory of Open Access Journals (Sweden)

Lars Christian Blichner

2015-03-01

Full Text Available On September 2009 the European Union (EU adopted a regulation banning the import of seal products into the EU or placing seal products on the EU market. The European Parliament was the main driving force behind the regulation and the EU has been criticised by affected countries outside the EU for not basing this decision on the available expert knowledge. The questions asked are how, given epistemic dependence, non-experts may challenge an expert based policy proposal. Can non-experts hold experts accountable, and if so in what way? Three main tests and ten subtests of expert knowledge are proposed and these tests are then used to assess whether the European Parliament did in fact argue in a way consistent with available expert knowledge in amending the Commission proposal for a regulation.

On epistemic uncertainties in event tree success criteria

International Nuclear Information System (INIS)

Jordan Cizelj, R.; Parzer, I.

2003-01-01

Uncertainty analysis of parameters, which are used as success criteria in PSA event trees, is presented in the paper. The influence of parameters on PSA model is indirect, and they are rather subject to epistemic uncertainties. Consequently, point estimates of these parameters cannot be automatically exchanged with probability distributions. For each PSA parameter, the analysis of several influencing factors is performed. As a result, recommended parameters' values for sensitivity analysis of the influence of these parameters on PSA results are given. In particular, the parameters related to exposure times were investigated. The values of the exposure times are assessed using different methodologies. The analysis of three parameters is presented in the paper, based on the comparison between the results of MAAP 3.0B and RELAP5/MOD2 codes. (author)

A new international environmental order? An assessment of the impact of the global warming epistemic community

International Nuclear Information System (INIS)

Smith, H.A.

1993-12-01

Global warming is a problem which ignores national boundaries, making international cooperation essential. The role of epistemic communities, or those composed of professionals who share a commitment to a common causal model and a set of political values, in affecting the international response to the global warming problem is examined. It is claimed that the epistemic global warming community can affect the policy process, both domestically and internationally, and facilitate cooperation in an era of ecological interdependence. This claim is explored and eventually supported through the examination of two case studies: the responses of Canada and Britain to the issue of global warming between 1988 and November 1990. The case studies are supplemented with a more general discussion of the issues surrounding the international politics of global warming through the same period. Through these studies, it is found that a global warming community can be identified and that its efforts have played a significant role in framing the global warming issue. 121 refs

The problem of epistemic jurisdiction in global governance: The case of sustainability standards for biofuels.

Science.gov (United States)

Winickoff, David E; Mondou, Matthieu

2017-02-01

While there is ample scholarly work on regulatory science within the state, or single-sited global institutions, there is less on its operation within complex modes of global governance that are decentered, overlapping, multi-sectorial and multi-leveled. Using a co-productionist framework, this study identifies 'epistemic jurisdiction' - the power to produce or warrant technical knowledge for a given political community, topical arena or geographical territory - as a central problem for regulatory science in complex governance. We explore these dynamics in the arena of global sustainability standards for biofuels. We select three institutional fora as sites of inquiry: the European Union's Renewable Energy Directive, the Roundtable on Sustainable Biomaterials, and the International Organization for Standardization. These cases allow us to analyze how the co-production of sustainability science responds to problems of epistemic jurisdiction in the global regulatory order. First, different problems of epistemic jurisdiction beset different standard-setting bodies, and these problems shape both the content of regulatory science and the procedures designed to make it authoritative. Second, in order to produce global regulatory science, technical bodies must manage an array of conflicting imperatives - including scientific virtue, due process and the need to recruit adoptees to perpetuate the standard. At different levels of governance, standard drafters struggle to balance loyalties to country, to company or constituency and to the larger project of internationalization. Confronted with these sometimes conflicting pressures, actors across the standards system quite self-consciously maneuver to build or retain authority for their forum through a combination of scientific adjustment and political negotiation. Third, the evidentiary demands of regulatory science in global administrative spaces are deeply affected by 1) a market for standards, in which firms and states can

Medical ethics and ethical dilemmas.

Science.gov (United States)

Iyalomhe, G B S

2009-01-01

Ethical problems routinely arise in the hospital and outpatient practice settings and times of dilemma do occur such that practitioners and patients are at cross-roads where choice and decision making become difficult in terms of ethics. This paper attempts a synopsis of the basic principles of medical ethics, identifies some ethical dilemmas that doctors often encounter and discusses some strategies to address them as well as emphasizes the need for enhanced ethics education both for physicians and patients particularly in Nigeria. Literature and computer programmes (Medline and PsychoInfo databases) were searched for relevant information. The search showed that the fundamental principles suggested by ethicists to assist doctors to evaluate the ethics of a situation while making a decision include respect for autonomy, beneficence, non-maleficence and justice. Although the above principles do not give answers as to how to handle a particular situation, they serve as a guide to doctors on what principles ought to apply to actual circumstances. The principles sometimes conflict with each other leading to ethical dilemmas when applied to issues such as abortion, contraception, euthanasia, professional misconduct, confidentiality truth telling, professional relationship with relatives, religion, traditional medicine and business concerns. Resolution of dilemmas demand the best of the doctor's knowledge of relevant laws and ethics, his training and experience, his religious conviction and moral principles as well as his readiness to benefit from ethics consultation and the advice of his colleagues. Ethics education should begin from the impressionable age in homes, continued in the medical schools and after graduation to ensure that doctors develop good ethical practices and acquire the ability to effectively handle ethical dilemmas. Also, education of patients and sanction of unethical behaviour will reduce ethical dilemmas.

Fukushima: an epistemic-political mutation

International Nuclear Information System (INIS)

Rieu, Alain-Marc

2016-01-01

While considering that a catastrophe always put a society into question again, and addressing the case of Fukushima, the author first wanders how this disruptive event became a collective experience at the Japan scale and at the World scale, which in turn builds up a field of knowledge which concerns all components of the social system. Thus, he tries to define the associated epistemic mutation which can be addressed through some basic questions: what happened actually? What have we learned? If the tsunami has been the trigger, the catastrophe has been made possible by the institutional system, and is human, social, technological, industrial and political. He outlines the political role played by energy industries in Japan, and notably in all different departments and ministries. The author then examines what can or may happen when such disruptive knowledge emerges, notably for the different powers (central power, media, education and research institutions). The author considers that a virtual dislocation of the power structure can be noticed in Japan since the 1970's, and that the Fukushima catastrophe is an undesired effect of a hierarchical stacking of power and influence poles. In the next part, he addresses the political issue as the whole State apparatus is accused. Finally, the author briefly discusses the philosophical dimension

The Ethics of Doing Ethics.

Science.gov (United States)

Hansson, Sven Ove

2017-02-01

Ethicists have investigated ethical problems in other disciplines, but there has not been much discussion of the ethics of their own activities. Research in ethics has many ethical problems in common with other areas of research, and it also has problems of its own. The researcher's integrity is more precarious than in most other disciplines, and therefore even stronger procedural checks are needed to protect it. The promotion of some standpoints in ethical issues may be socially harmful, and even our decisions as to which issues we label as "ethical" may have unintended and potentially harmful social consequences. It can be argued that ethicists have an obligation to make positive contributions to society, but the practical implications of such an obligation are not easily identified. This article provides an overview of ethical issues that arise in research into ethics and in the application of such research. It ends with a list of ten practical proposals for how these issues should be dealt with.

[Continuing education in ethics: from clinical ethics to institutional ethics].

Brazeau-Lamontagne, Lucie

2012-01-01

The mandate of the Ethics Committee of the Conseil de médecins, dentistes et pharmaciens (CMDP) at the Centre hospitalier universitaire de Sherbrooke (CHUS), Sherbrooke, Quebec is three-fold: to guide the clinical decision; to address the institutional ethical function; to create the program for continuing education in ethics (Formation éthique continue or FEC). Might FEC be the means of bridging from individual ethics to institutional ethics at a hospital? To take the FEC perspectives considered appropriate for doctors and consider them for validation or disproving in the context of those of other professionals. Situate the proposed FEC mandate in a reference framework to evaluate (or triangulate) the clinical decision and the institutional ethic. CONVICTION: Sustainable professional development for doctors (DPD) includes ethics; it cannot be ignored. Without constant attention to upgrading one's abilities in professional ethics, these suffer the same fate as other professional aptitudes and competences (for example, techniques and scientific knowledge): decay.

Epistemic companions: shared reality development in close relationships.

Science.gov (United States)

Rossignac-Milon, Maya; Higgins, E Tory

2018-01-11

We propose a framework outlining the development of shared reality in close relationships. In this framework, we attempt to integrate disparate close relationship phenomena under the conceptual umbrella of shared reality. We argue that jointly satisfying epistemic needs-making sense of the world together-plays an important but under-appreciated role in establishing and maintaining close relationships. Specifically, we propose that dyads progress through four cumulative phases in which new forms of shared reality emerge. Relationships are often initiated when people discover Shared Feelings, which then facilitate the co-construction of dyad-specific Shared Practices. Partners then form an interdependent web of Shared Coordination and ultimately develop a Shared Identity. Each emergent form of shared reality continues to evolve throughout subsequent phases, and, if neglected, can engender relationship dissolution. Copyright © 2018 Elsevier Ltd. All rights reserved.

Self-concept deficits in massively multiplayer online role-playing games addiction.

Leménager, Tagrid; Gwodz, Alexander; Richter, Anne; Reinhard, Iris; Kämmerer, Nina; Sell, Madlen; Mann, Karl

2013-01-01

Previous studies on Internet addiction point towards a particular constellation of personality traits and deficits in social competence of players addicted to massively multiplayer online role-playing games (MMORPGs), which are hypothesized to result from impairments in self-concept. The aim of this study was to examine differences in self-concept and degree of avatar identification in World of Warcraft addicted, non-addicted and naive (nonexperienced) participants. Participants (n = 45) completed interviews and self-report questionnaires on social, emotional and physical aspects of self-concept. Attributes of participants' 'actual self', 'ideal self' and their avatar were assessed using the Giessen test. The extent of avatar identification was examined by assessing differences between 'ideal self' and avatar evaluations. In contrast to nonaddicted and naive participants, addicted players showed a more negative body appraisal and lower self-esteem as well as lower permeability, social response, general mood and social potency on the Giessen test subscales. They further showed significantly lower discrepancies between 'ideal self' and avatar ratings on nearly all Giessen test subscales. The results point towards impairments in self-concept and a higher degree in avatar identification in addicted MMORPG players compared to the remaining participants. These results could have important implications for the treatment of addicted MMORPG players. Copyright © 2013 S. Karger AG, Basel.

The newly emerging field of machine ethics (Anderson and Anderson 2006) is concerned with adding an ethical dimension to machines. Unlike computer ethics -- which has traditionally focused on ethical issues surrounding humans' use of machines -- machine ethics is concerned with ensuring that the behavior of machines toward human users, and perhaps other machines as well, is ethically acceptable. In this article we discuss the importance of machine ethics, the need for machines that represent ...

SecurityCom: A Multi-Player Game for Researching and Teaching Information Security Teams

Directory of Open Access Journals (Sweden)

Douglas P. Twitchell

2007-12-01

Full Text Available A major portion of government and business organizations’ attempts to counteract information security threats is teams of security personnel.  These teams often consist of personnel of diverse backgrounds in specific specialties such as network administration, application development, and business administration, resulting in possible conflicts between security, functionality, and availability.  This paper discusses the use of games to teach and research information security teams and outlines research to design and build a simple, team-oriented, configurable, information security game. It will be used to study how information security teams work together to defend against attacks using a multi-player game, and to study the use of games in training security teams.  Studying how information security teams work, especially considering the topic of shared-situational awareness, could lead to better ways of forming, managing, and training teams.  Studying the effectiveness of the game as a training tool could lead to better training for security teams. 

Discrete-Time Nonzero-Sum Games for Multiplayer Using Policy-Iteration-Based Adaptive Dynamic Programming Algorithms.

Science.gov (United States)

Zhang, Huaguang; Jiang, He; Luo, Chaomin; Xiao, Geyang

2017-10-01

In this paper, we investigate the nonzero-sum games for a class of discrete-time (DT) nonlinear systems by using a novel policy iteration (PI) adaptive dynamic programming (ADP) method. The main idea of our proposed PI scheme is to utilize the iterative ADP algorithm to obtain the iterative control policies, which not only ensure the system to achieve stability but also minimize the performance index function for each player. This paper integrates game theory, optimal control theory, and reinforcement learning technique to formulate and handle the DT nonzero-sum games for multiplayer. First, we design three actor-critic algorithms, an offline one and two online ones, for the PI scheme. Subsequently, neural networks are employed to implement these algorithms and the corresponding stability analysis is also provided via the Lyapunov theory. Finally, a numerical simulation example is presented to demonstrate the effectiveness of our proposed approach.

Xu, Menghui; Du, Xiaoping; Qiu, Zhiping; Wang, Chong

2016-03-01

A dimension-wise method for predicting fuzzy energy flows between structural vibrating systems coupled by joints with epistemic uncertainties is established. Based on its Legendre polynomial approximation at α=0, both the minimum and maximum point vectors of the energy flow of interest are calculated dimension by dimension within the space spanned by the interval parameters determined by fuzzy those at α=0 and the resulted interval bounds are used to assemble the concerned fuzzy energy flows. Besides the proposed method, vertex method as well as two current methods is also applied. Comparisons among results by different methods are accomplished by two numerical examples and the accuracy of all methods is simultaneously verified by Monte Carlo simulation.

Two sides of the same coin? The (techno)epistemic cultures of systems and synthetic biology.

Science.gov (United States)

Kastenhofer, Karen

2013-06-01

Systems and synthetic biology both emerged around the turn of this century as labels for new research approaches. Although their disciplinary status as well as their relation to each other is rarely discussed in depth, now and again the idea is invoked that both approaches represent 'two sides of the same coin'. The following paper focuses on this general notion and compares it with empirical findings concerning the epistemic cultures prevalent in the two contexts. Drawing on interviews with researchers from both fields, on participatory observation in conferences and courses and on documentary analysis, this paper delineates differences and similarities, incompatibilities and blurred boundaries. By reconstructing systems and synthetic biology's epistemic cultures, this paper argues that they represent two 'communities of vision', encompassing heterogeneous practices. Understanding the relation of the respective visions of understanding nature and engineering life is seen as indispensible for the characterisation of (techno)science in more general terms. Depending on the conceptualisation of understanding and construction (or: science and engineering), related practices such as in silico modelling for enhancing understanding or enabling engineering can either be seen as incommensurable or 'two sides of one coin'.

Ethics rounds: An appreciated form of ethics support.

Silén, Marit; Ramklint, Mia; Hansson, Mats G; Haglund, Kristina

2016-03-01

Ethics rounds are one way to support healthcare personnel in handling ethically difficult situations. A previous study in the present project showed that ethics rounds did not result in significant changes in perceptions of how ethical issues were handled, that is, in the ethical climate. However, there was anecdotal evidence that the ethics rounds were viewed as a positive experience and that they stimulated ethical reflection. The aim of this study was to gain a deeper understanding of how the ethics rounds were experienced and why the intervention in the form of ethics rounds did not succeed in improving the ethical climate for the staff. An exploratory and descriptive design with a qualitative approach was adopted, using individual interviews. A total of 11 healthcare personnel, working in two different psychiatry outpatient clinics and with experience of participating in ethics rounds, were interviewed. The study was based on informed consent and was approved by one of the Swedish Regional Ethical Review Boards. The participants were generally positive about the ethics rounds. They had experienced changes by participating in the ethics rounds in the form of being able to see things from different perspectives as well as by gaining insight into ethical issues. However, these changes had not affected daily work. A crucial question is whether or not increased reflection ability among the participants is a good enough outcome of ethics rounds and whether this result could have been measured in patient-related outcomes. Ethics rounds might foster cooperation among the staff and this, in turn, could influence patient care. By listening to others during ethics rounds, a person can learn to see things from a new angle. Participation in ethics rounds can also lead to better insight concerning ethical issues. © The Author(s) 2014.

Negotiating contingent knowledges in a time of epistemic doubt

DEFF Research Database (Denmark)

Phillips, Louise Jane

How can/should we produce and communicate social scientific knowledge with authority under conditions of epistemic doubt? If all knowledge is contingent and if truth is a discursive effect rather than the final claim about reality - as post-foundationalism suggests - how can we formulate...... and provide support for contingent knowledge-claims? And how can the communication of social scientificknowlege be theorised and practised as the negotiation between social scientific knowledge and other forms of contingent knowledge rather than the one-way transmission of universal, value-free truth......-claims? In the paper, I outline an approach to addressing the final question. The approach is based on a combination of approaches to the production of knowledge developed in post-foundationalist sociology and philosophy of science, approaches to the communication of knowlege developed within communication studies...

Online-offline activities and game-playing behaviors of avatars in a massive multiplayer online role-playing game

Science.gov (United States)

Jiang, Zhi-Qiang; Zhou, Wei-Xing; Tan, Qun-Zhao

2009-11-01

Massive multiplayer online role-playing games (MMORPGs) are very popular in China, which provides a potential platform for scientific research. We study the online-offline activities of avatars in an MMORPG to understand their game-playing behavior. The statistical analysis unveils that the active avatars can be classified into three types. The avatars of the first type are owned by game cheaters who go online and offline in preset time intervals with the online duration distributions dominated by pulses. The second type of avatars is characterized by a Weibull distribution in the online durations, which is confirmed by statistical tests. The distributions of online durations of the remaining individual avatars differ from the above two types and cannot be described by a simple form. These findings have potential applications in the game industry.

Several studies have linked massively multiplayer online role-playing games (MMORPGs) with possible problematic usage or internet addiction. The main goal of the present study was to assess links between motivations to play in MMORPGs and addictive involvement in such types of games. A total of 696 gamers responded to an online survey. Five distinct motivations to play were identified in gamers: achievement, socializing, immersion, relaxing and escaping. Multiple regression analysis revealed that addictive MMORPG use patterns are predicted by achievement, escapism and socializing motives. Gender was also a significant predictor of problematic involvement in MMORPGs. Moreover, addictive MMORPG use positively correlated with the weekly time devoted to playing MMORPGs.

This study investigated the relationship between ethical leadership and ethical sales behavior. A total of 248 matched surveys with participant responses from insurance agents and their customers were collected. The insurance agents were asked to rate the ethical leadership of their leaders, the ethical climate in their organization, and their individual moral identity. Customers were asked to rate the perceived ethical sales behavior of the insurance agents. This empirical study utilized moderated mediation techniques to analyze the data. Results indicated that ethical climate mediated the relationship between ethical leadership and ethical sales behavior when moral identity was high, however, did not when moral identity was low. The research framework including contextual effects (i.e., ethical climate) and individual differences in moral judgment (i.e., moral identity) can provide a comprehensive picture of how ethical leadership influences ethical sales behavior. Theoretical and practical implications of these findings are also discussed.

Professional Ethics of Software Engineers: An Ethical Framework.

Science.gov (United States)

Lurie, Yotam; Mark, Shlomo

2016-04-01

The purpose of this article is to propose an ethical framework for software engineers that connects software developers' ethical responsibilities directly to their professional standards. The implementation of such an ethical framework can overcome the traditional dichotomy between professional skills and ethical skills, which plagues the engineering professions, by proposing an approach to the fundamental tasks of the practitioner, i.e., software development, in which the professional standards are intrinsically connected to the ethical responsibilities. In so doing, the ethical framework improves the practitioner's professionalism and ethics. We call this approach Ethical-Driven Software Development (EDSD), as an approach to software development. EDSD manifests the advantages of an ethical framework as an alternative to the all too familiar approach in professional ethics that advocates "stand-alone codes of ethics". We believe that one outcome of this synergy between professional and ethical skills is simply better engineers. Moreover, since there are often different software solutions, which the engineer can provide to an issue at stake, the ethical framework provides a guiding principle, within the process of software development, that helps the engineer evaluate the advantages and disadvantages of different software solutions. It does not and cannot affect the end-product in and of-itself. However, it can and should, make the software engineer more conscious and aware of the ethical ramifications of certain engineering decisions within the process.

Bipartite Graphs as Models of Population Structures in Evolutionary Multiplayer Games

Science.gov (United States)

Peña, Jorge; Rochat, Yannick

2012-01-01

By combining evolutionary game theory and graph theory, “games on graphs” study the evolutionary dynamics of frequency-dependent selection in population structures modeled as geographical or social networks. Networks are usually represented by means of unipartite graphs, and social interactions by two-person games such as the famous prisoner’s dilemma. Unipartite graphs have also been used for modeling interactions going beyond pairwise interactions. In this paper, we argue that bipartite graphs are a better alternative to unipartite graphs for describing population structures in evolutionary multiplayer games. To illustrate this point, we make use of bipartite graphs to investigate, by means of computer simulations, the evolution of cooperation under the conventional and the distributed N-person prisoner’s dilemma. We show that several implicit assumptions arising from the standard approach based on unipartite graphs (such as the definition of replacement neighborhoods, the intertwining of individual and group diversity, and the large overlap of interaction neighborhoods) can have a large impact on the resulting evolutionary dynamics. Our work provides a clear example of the importance of construction procedures in games on graphs, of the suitability of bigraphs and hypergraphs for computational modeling, and of the importance of concepts from social network analysis such as centrality, centralization and bipartite clustering for the understanding of dynamical processes occurring on networked population structures.

Aspiration dynamics of multi-player games in finite populations.

Du, Jinming; Wu, Bin; Altrock, Philipp M; Wang, Long

2014-05-06

On studying strategy update rules in the framework of evolutionary game theory, one can differentiate between imitation processes and aspiration-driven dynamics. In the former case, individuals imitate the strategy of a more successful peer. In the latter case, individuals adjust their strategies based on a comparison of their pay-offs from the evolutionary game to a value they aspire, called the level of aspiration. Unlike imitation processes of pairwise comparison, aspiration-driven updates do not require additional information about the strategic environment and can thus be interpreted as being more spontaneous. Recent work has mainly focused on understanding how aspiration dynamics alter the evolutionary outcome in structured populations. However, the baseline case for understanding strategy selection is the well-mixed population case, which is still lacking sufficient understanding. We explore how aspiration-driven strategy-update dynamics under imperfect rationality influence the average abundance of a strategy in multi-player evolutionary games with two strategies. We analytically derive a condition under which a strategy is more abundant than the other in the weak selection limiting case. This approach has a long-standing history in evolutionary games and is mostly applied for its mathematical approachability. Hence, we also explore strong selection numerically, which shows that our weak selection condition is a robust predictor of the average abundance of a strategy. The condition turns out to differ from that of a wide class of imitation dynamics, as long as the game is not dyadic. Therefore, a strategy favoured under imitation dynamics can be disfavoured under aspiration dynamics. This does not require any population structure, and thus highlights the intrinsic difference between imitation and aspiration dynamics.

The development of computer ethics: contributions from business ethics and medical ethics.

Science.gov (United States)

Wong, K; Steinke, G

2000-04-01

In this essay, we demonstrate that the field of computer ethics shares many core similarities with two other areas of applied ethics. Academicians writing and teaching in the area of computer ethics, along with practitioners, must address ethical issues that are qualitatively similar in nature to those raised in medicine and business. In addition, as academic disciplines, these three fields also share some similar concerns. For example, all face the difficult challenge of maintaining a credible dialogue with diverse constituents such as academicians of various disciplines, professionals, policymakers, and the general public. Given these similarities, the fields of bioethics and business ethics can serve as useful models for the development of computer ethics.

Rapid advances in modern computing and information technology have enabled millions of people to interact online via various social network and gaming services. The widespread adoption of such online services have made possible analysis of large-scale archival data containing detailed human interactions, presenting a very promising opportunity to understand the rich and complex human behavior. In collaboration with a leading global provider of Massively Multiplayer Online Role-Playing Games (MMORPGs), here we present a network science-based analysis of the interplay between distinct types of user interaction networks in the virtual world. We find that their properties depend critically on the nature of the context-interdependence of the interactions, highlighting the complex and multilayered nature of human interactions, a robust understanding of which we believe may prove instrumental in the designing of more realistic future virtual arenas as well as provide novel insights to the science of collective human behavior.

Epistemic Function and Ontology of Analog and Digital Images

2016-01-01

Full Text Available The important epistemic function of photographic images is their active role in construction and reconstruction of our beliefs concerning the world and human identity, since we often consider photographs as presenting reality or even the Real itself. Because photography can convince people of how different social and ethnic groups and even they themselves look, documentary projects and the dissemination of photographic practices supported the transition from disciplinary society to the present-day society of control. While both analog and digital images are formed from the same basic materia, the ways in which this matter appears are distinctive. In the case of analog photography, we deal with physical and chemical matter, whereas with digital images we face electronic matter. Because digital photography allows endless modification of the image, we can no longer believe in the truthfulness of digital images.

Epistemic Purposes to Prompt Argumentation in inquiry-based classes

Full Text Available Considering the growth in interest on argumentation in research on science education, in this paper our goal is to propose an overview of actions taken by a teacher that made possible to establish and mediate production of arguments by the students in classroom. For this purpose, we analyze a physics lesson where discussions were about light duality, through a planned inquiry-based sequence teaching. We developed a set of codes called Epistemic Purposes for Promotion of Argumentation that allow understanding teacher's purposes as well his actions to promote argumentation among students during inquiry-based lessons. According to theoretical proposition and empirical analysis, it was revealed that the construction of arguments by students has a high dependence on how ideas are problematized by teacher. The construction of understanding  by students requires teacher actions that result in contributions of different kinds.

Edlich, Stefan; Hoerning, Henrik; Brunnert, Andreas; Hoerning, Reidar

2005-03-01

The development of massive multiplayer games (MMPGs) for personal computers is based on a wide range of frameworks and technologies. In contrast, MMPG development for cell phones lacks the availability of framework support. We present Aorta as a multi-purpose lightweight MIDP 2.0 framework to support the transparent and equal API usage of peer-to-peer communication via http, IP and Bluetooth. Special experiments, such as load-tests on Nokia 6600s, have been carried out with Bluetooth support in using a server-as-client architecture to create ad-hoc networks by using piconet functionalities. Additionally, scatternet functionalities, which will be supported in upcoming devices, have been tested in a simulated environment on more than 12 cell phones. The core of the Aorta framework is the Etherlobby, which manages connections, peers, the game lobby, game policies and much more. The framework itself was developed to enable the fast development of mobile games, regardless of the distance between users, which might be within the schoolyard or much further away. The earliest market-ready application shown here is a multimedia game for cell phones utilizing all of the frameworks features. This game, called Micromonster, acts as platform for developer tests, as well as providing valuable information about interface usability and user acceptance.

Insights from Massively Multiplayer Online Role Playing Games to Enhance Gamification in Education

Full Text Available This paper presents the results of the study of a cohort of college graduate and undergraduate students who participated in playing a Massively Multiplayer Online Role Playing Game (MMORPG as a gameplay rich with social interaction as well as intellectual and aesthetic features. Statistically significant differences among our participants' perception, sensation seeking, and satisfaction in relation to gameplay features are investigated. Our primary objective in this investigation was to look for certain aspects of game playing and sensation seeking that attracts a group of students to engage in long term gameplay online. Results support the majority of pre-planned hypotheses and show potential important considerations to take into account when developing gamified content for educational applications. Furthermore, the limitation of the data used in this study is presented and future directions to remove the current limitation and proliferate results through qualitative research into players' in-game social interactions. We suggest that finding similarities and underlying patterns of attraction among a diverse group of students could be beneficial in designing gameplay features to enhance student participation in the learning experience and improve learning performance.

A Legal and Ethical Analysis of the Effects of Triggering Conditions on Surrogate Decision-Making in End-of-Life Care in the US.

Science.gov (United States)

Clint Parker, J; Goldberg, Daniel S

2016-03-01

The central claim of this paper is that American states' use of so-called "triggering conditions" to regulate surrogate decision-making authority in end-of-life care leaves unresolved a number of important ethical and legal considerations regarding the scope of that authority. The paper frames the issue with a case set in a jurisdiction in which surrogate authority to withdraw life-sustaining treatment is triggered by two specific clinical conditions. The case presents a quandary insofar as the clinical facts do not satisfy the triggering conditions, and yet both the appropriate surrogates and the care team agree that withdrawal of life-sustaining treatment is in the best interest of the patient. The paper surveys applicable law across the 50 states and weighs the arguments for and against the inclusion of such triggering conditions in relevant legal regimes. The paper concludes by assessing the various legal and policy options states have for regulating surrogate decision-making authority in light of the moral considerations (including epistemic difficulties), and notes the possibility for conflict within ethics teams arising from the potential tension between prudence, risk-aversion, and moral obligation.

The 2008 performance assessment (PA) for the proposed repository for high-level radioactive waste at Yucca Mountain (YM), Nevada, illustrates the conceptual structure of risk assessments for complex systems. The 2008 YM PA is based on the following three conceptual entities: a probability space that characterizes aleatory uncertainty; a function that predicts consequences for individual elements of the sample space for aleatory uncertainty; and a probability space that characterizes epistemic uncertainty. These entities and their use in the characterization, propagation and analysis of aleatory and epistemic uncertainty are described and illustrated with results from the 2008 YM PA.

What Role for Law, Human Rights, and Bioethics in an Age of Big Data, Consortia Science, and Consortia Ethics? The Importance of Trustworthiness.

The global bioeconomy is generating new paradigm-shifting practices of knowledge co-production, such as collective innovation; large-scale, data-driven global consortia science (Big Science); and consortia ethics (Big Ethics). These bioeconomic and sociotechnical practices can be forces for progressive social change, but they can also raise predicaments at the interface of law, human rights, and bioethics. In this article, we examine one such double-edged practice: the growing, multivariate exploitation of Big Data in the health sector, particularly by the private sector. Commercial exploitation of health data for knowledge-based products is a key aspect of the bioeconomy and is also a topic of concern among publics around the world. It is exacerbated in the current age of globally interconnected consortia science and consortia ethics, which is characterized by accumulating epistemic proximity, diminished academic independence, "extreme centrism", and conflicted/competing interests among innovation actors. Extreme centrism is of particular importance as a new ideology emerging from consortia science and consortia ethics; this relates to invariably taking a middle-of-the-road populist stance, even in the event of human rights breaches, so as to sustain the populist support needed for consortia building and collective innovation. What role do law, human rights, and bioethics-separate and together-have to play in addressing these predicaments and opportunities in early 21st century science and society? One answer we propose is an intertwined ethico-legal normative construct, namely trustworthiness . By considering trustworthiness as a central pillar at the intersection of law, human rights, and bioethics, we enable others to trust us, which in turns allows different actors (both nonprofit and for-profit) to operate more justly in consortia science and ethics, as well as to access and responsibly use health data for public benefit.

Imaginative ethics--bringing ethical praxis into sharper relief.

Science.gov (United States)

Hansson, Mats G

2002-01-01

The empirical basis for this article is three years of experience with ethical rounds at Uppsala University Hospital. Three standard approaches of ethical reasoning are examined as potential explanations of what actually occurs during the ethical rounds. For reasons given, these are not found to be satisfying explanations. An approach called "imaginative ethics", is suggested as a more satisfactory account of this kind of ethical reasoning. The participants in the ethical rounds seem to draw on a kind of moral competence based on personal life experience and professional competence and experience. By listening to other perspectives and other experiences related to one particular patient story, the participants imagine alternative horizons of moral experience and explore a multitude of values related to clinical practice that might be at stake. In his systematic treatment of aesthetics in the Critique of Judgement, Kant made use of an operation of thought that, if applied to ethics, will enable us to be more sensitive to the particulars of each moral situation. Based on this reading of Kant, an account of imaginative ethics is developed in order to bring the ethical praxis of doctors and nurses into sharper relief. The Hebraic and the Hellenic traditions of imagination are used in order to illuminate some of the experiences of ethical rounds. In conclusion, it is argued that imaginative ethics and principle-based ethics should be seen as complementary in order to endow a moral discourse with ethical authority. Kantian ethics will do the job if it is remembered that Kant suggested only a modest, negative role of principle-based deliberation.

In times of increasing global uncertainties, science takes a central position for policy decisions. According to Peter M. Haas, epistemic communities are able to influence the cooperative behavior of states through their consensual knowledge. This book critically examines this statement. As the case of the Framework Convention on Climate Change shows, the World Climate Council (IPCC) was not in a position to enforce its solution options in the intergovernmental negotiations, as these affected the individual convictions of the decision-makers. While Angela Merkel advocated an agreement, the US government under George W. Bush denied the existence of climate change. Decision-makers and their individual convictions must therefore have a greater significance in international politics. [German] In Zeiten zunehmender globaler Unsicherheiten nimmt die Wissenschaft fuer die Entscheidungen der Politik eine zentrale Stellung ein. Epistemic communities sind nach Peter M. Haas durch ihr konsensuales Wissen in der Lage, das Kooperationsverhalten von Staaten zu beeinflussen. Das vorliegende Buch prueft diese Aussage kritisch. Wie der Fall der Klimarahmenkonvention zeigt, war der Weltklimarat (IPCC) nicht in der Lage, seine Loesungsoptionen in den zwischenstaatlichen Verhandlungen durchzusetzen, da diesen die individuellen Ueberzeugungen der Entscheidungstraeger entgegenstanden. Waehrend Angela Merkel ein Abkommen befuerwortete, bestritt die US-Regierung unter George W. Bush die Existenz des Klimawandels. Entscheidungstraegern und ihren individuellen Ueberzeugungen muss daher in der internationalen Politik eine staerkere Bedeutung zukommen.

Tuskegee University experience challenges conventional wisdom: is integrative bioethics practice the new ethics for the public's health?

Science.gov (United States)

Sodeke, Stephen Olufemi

2012-11-01

The Tuskegee University National Center for Bioethics in Research and Health Care was established in 1999 in partial response to the Presidential Apology for the United States Public Health Service's Study of Untreated Syphilis in the Negro Male conducted in Macon County, Alabama, from 1932 to 1972. The Center's mission of promoting equity and justice in health and health care for African Americans and other underserved populations employs an integrative bioethics approach informed by moral vision. Etymological and historical analyses are used to delineate the meaning and evolution of bioethics and to provide a basis for Tuskegee's integrative bioethics niche. Unlike mainstream bioethics, integrative bioethics practice is holistic in orientation, and more robust for understanding the epistemic realities of minority life, health disparities, and population health. The conclusion is that integrative bioethics is relevant to the survival of all people, not just a privileged few; it could be the new ethics for the public's health.

How Should Ethical Theories Be Dealt with in Engineering Ethics?

Science.gov (United States)

Ohishi, Toshihiro

Contemporary engineering ethics scholars deal with contesting several ethical theories without criticizing them radically and try to use them to solve ethical problems. In this paper I first show that a conflict between ethical theories is not superficial, and pragmatic methods are adopted in engineering ethics. Second, I claim that the way to deal with contesting ethical theories in contemporary engineering ethics has an unacceptable side which does not accord with my argument that a conflict between ethical theories is not superficial and pragmatic methods are adopted in engineering ethics. Finally, I conclude that this inconsistency in contemporary engineering ethics should be corrected to make contemporary engineering ethics consistent.

Ethics Management: How to Achieve Ethical Organizations and Management?

Carita Lilian Snellman

2015-12-01

Full Text Available The last decades’ serious organizational scandals that mainly stem from corruption and conflicting interests but also from bribery, favoritism and other wrongdoings have ac-centuated the need for finding instruments for achieving more ethical organizations and management. Ethics management is particularly important in the public sector because public employees and holders of public office are responsible for increasing wellbeing and providing common good for all citizens. Only accountable management striving for integrity through ethical practices and decision making will guarantee ethical organiza-tional behavior. In spite of increasing research on ethics in general and ethics manage-ment in particular, increase in organizational scandals indicates that there is knowledge gap concerning ethical instruments that help to solve ethical problems. The aim of this paper is to shed light on ethical theories and instruments, and wrongdoings in public sec-tor organizations. The main questions are; why is there so much wrongdoing; how can it be reduced; and how can more ethical organization and management be achieved. This is a review paper aiming to provide a review of ethical theories and instruments and dis-cuss serious wrongdoings and the role of ethics in the public sector. The paper contrib-utes to the fields of management and organization, ethics, and public management.

Has the Deliberative Model of Democracy an epistemic value?

Roberto García

2013-07-01

Full Text Available Deliberative democracy is a normative ideal of democracy. This model is a proposal for the regeneration of the legitimacy of our institutions, but also a mechanism for decision making. It is based on two different dimensions: a procedural dimension where the model demands the inclusion and an equal capacity to influence the final decision of all those affected (Cohen, 1989; Bohman, 1996; Habermas, 1992 ... and a substantive dimension where the political decisions are made through a collective procedure of argumentation and public discussion. If these conditions are recognized, the decisions will be more rational and better decisions. This paper has two aims. First I will present the key elements of this epistemic conception of political legitimacy. Second I will show the challenges it faces. On a one hand, the counterfactual of many of its postulates and on the other, the obvious problems of bias consensualist of this model.

2011-09-01

Full Text Available The paper intends to explore the ethical ideology and ethical judgments of accounting practitioners in Malaysia. The objectives of this study are twofold. First, the paper intends to examine the factors that contribute to the different ethical ideology among Malaysian accounting practitioners. Second, it aims to investigate the influence of demographic factors and ethical ideology on ethical judgments of accounting practitioners. The study used Forsyth’s (1980 Ethics Position Questionnaire instrument to examine the ethical ideology of the accountants and adopted ethics vignettes used by Emerson et al. (2007 to assess the ethical judgments of the respondents. From the statistical analysis, this study found that age and gender have a significant impact on ethical judgment but not on ethical ideology. In addition, idealism and relativism have a significant influence on ethical judgment, especially in a legally unethical situation.

Hendrik R. Lloyd

2010-11-01

Research purpose: The main aim of the paper is to analyse the impact of business ethics in the Eastern Cape Motor Industry Cluster (ECMIC and the different perceptions regarding such ethics. This is based on the main research question, namely, whether a business ethics model should be developed to assist in creating an ethical organisation. Motivation of the study: The motivation for this study is based on the question of whether there is a dedicated drive within the motor industry to establish an ethical organisation and, if such is the case, what benefits would accrue to the organisations in ECMIC. Research design, approach and method: An empirical study was conducted within ECMIC to test the proposed ethics intervention model. A questionnaire, as the main measuring instrument, was developed and 150 questionnaires were distributed. Statistical hypothesis testing was used, with a significance level set at 5%. The aim of the hypothesis testing was to test whether the percentage responses in certain categories were significantly higher than a pre-determined test-value. Main findings: The research results substantiate the fact that the majority of the surveyed organisations do not implement specific ethics interventions. Nevertheless, the majority of respondents acknowledge the importance of ethical behaviour in the organisation, especially with regard to their financial positions. Practical/managerial implications: From this study it became clear that the implementation of a code of ethics would create a platform for ethical behaviour in organisations. It is also concluded from this study that all organisations must strive towards creating an ethical organisation which would have long-term rewards for the organisation, especially from a financial perspective. Contribution/value-add: This study highlights the fact that although ethics and ethical behaviour in organisations are emphasised and receive wide-spread media coverage, not enough action is linked to this task

When clinical ethics committee members discuss a complex ethical dilemma, what use do they have for normative ethical theories? Members without training in ethical theory may still contribute to a pointed and nuanced analysis. Nonetheless, the knowledge and use of ethical theories can play four important roles: aiding in the initial awareness and identification of the moral challenges, assisting in the analysis and argumentation, contributing to a sound process and dialogue, and inspiring an attitude of reflexivity. These four roles of ethical theory in clinical ethics consultation are described and their significance highlighted, while an example case is used as an illustration throughout.

A Study of Interaction Patterns and Awareness Design Elements in a Massively Multiplayer Online Game

2008-01-01

Full Text Available Massively multiplayer online games (MMOGs have been known to create rich and versatile social worlds for thousands of millions of players to participate. As such, various game elements and advance technologies such as artificial intelligence have been applied to encourage and facilitate social interactions in these online communities, the key to the success of MMOGs. However, there is a lack of studies addressing the usability of these elements in games. In this paper, we look into interaction patterns and awareness design elements that support the awareness in LastWorld and FairyLand. Experimental results obtained through both in-game experiences and player interviews reveal that not all awareness tools (e.g., an in-game map have been fully exploited by players. In addition, those players who are aware of these tools are not satisfied with them. Our findings suggest that awareness-oriented tools/channels should be easy to interpret and rich in conveying “knowledge” so as to reduce players-cognitive overload. These findings of this research recommend considerations of early stage MMOG design.

Recently, there have been growing concerns about excessive online gaming. Playing Massively Multiplayer Online Role-Playing Games (MMORPGs) appears to be particularly problematic, because these games require a high degree of commitment and time investment from the players to the detriment of occupational, social, and other recreational activities and relations. A number of gaming motives have been linked to excessive online gaming in adolescents and young adults. We assessed 175 current MMORPG players and 90 nonplayers using a Web-based questionnaire regarding their gaming behavior, problems as consequences of gaming, and game motivations and tested their statistical associations. Results indicated that (a) MMORPG players are significantly more likely to experience gaming-related problems relative to nonplayers, and that (b) the gaming motivations escapism and mechanics significantly predicted excessive gaming and appeared as stronger predictors than time investment in game. The findings support the necessity of using measures that distinguish between different types of online games. In addition, this study proves useful regarding the current discussion on establishing (online) gaming addiction as a diagnosis in future categorizations of psychopathology.

Tadmor, Carmit T; Hong, Ying-Yi; Chao, Melody M; Wiruchnipawan, Fon; Wang, Wei

2012-11-01

In 6 studies, we systematically explored for the 1st time the ameliorative effects of multicultural experience on intergroup bias and investigated the role of epistemic unfreezing as the motivational mechanism underlying these effects. We found that multicultural exposure led to a reduction in stereotype endorsement (Studies 1, 4, and 6), symbolic racism (Study 5), and discriminatory hiring decisions (Study 2). We further demonstrated that experimental exposure to multicultural experience caused a reduction in need for cognitive closure (NFCC; Studies 3 and 6) and that the ameliorative effects of multiculturalism experience on intergroup bias were fully mediated by lower levels of NFCC (Studies 4, 5, and 6). The beneficial effects of multiculturalism were found regardless of the targeted stereotype group (African Americans, Ethiopians, homosexuals, and native Israelis), regardless of whether multicultural experience was measured or manipulated, and regardless of the population sampled (Caucasian Americans or native Israelis), demonstrating the robustness of this phenomenon. Overall, these results demonstrate that multicultural experience plays a critical role in increasing social tolerance through its relationship to motivated cognitive processes.

Epistemic brokerage in the bio-property narrative: contributions to explaining opposition to transgenic technologies in agriculture.

Science.gov (United States)

Herring, Ronald J

2010-11-30

Unlike some global contentions - abolition of slavery, or universal franchise, for example - the rift over rDNA crops is not about ultimate values. Improvement of farmer welfare and enhanced sustainability of agriculture are universally valued goals. However, means to those ends are politically disputed; that dispute depends on alternative empirical stories about biotechnology, sometimes even alternative epistemologies. Opposition revolves around two fundamental dimensions: bio-safety and bio-property. There is convergence of these dimensions around exceptional risk and vulnerability to corporate control of farmers, but these are analytically separable questions of fact. This paper concentrates on bio-property. Epistemic brokers have successfully established knowledge claims that simultaneously undermine the case for rDNA technologies as potential contributors to development and motivate opposition. Epistemic brokers command authority from their positions at junctures of networks, enabling the screening, weighting, theorizing and diffusion of contentious empirical accounts. In contentions of low information, high information costs and diffuse anxiety, these claims provide cognitive support for opposition to 'GMOs'. Specifically, claims of patents, monopoly corporate control and terminator technology have diffused to and from India in global networks. Though effective in transnational advocacy networks, these claims have proved either false or inconsistent with dynamics on the ground. Copyright © 2010 Elsevier B.V. All rights reserved.

However, the efforts to integrate ethical values in educational system will not work well if there are no moral commitments implanted in the individuals.  Islam with its divine values plays the notable role to embed cognitive ethical values. It emphasizes on the unity of God, the accountability to God and the concept of maslahah (public benefits to be the foundations of ethics. Incorporating Islamic ethics into the system will be a significant contribution towards generating ethical accounting education. This paper attempts to elucidate how the Islamic ethics contribute its role towards ethical accountants as the products of accounting education.

Heritage ethics: Toward a thicker account of nursing ethics.

Fowler, Marsha D

2016-02-01

The key to understanding the moral identity of modern nursing and the distinctiveness of nursing ethics resides in a deeper examination of the extensive nursing ethics literature and history from the late 1800s to the mid 1960s, that is, prior to the "bioethics revolution". There is a distinctive nursing ethics, but one that falls outside both biomedical and bioethics and is larger than either. Were, there a greater corpus of research on nursing's heritage ethics it would decidedly recondition the entire argument about a distinctive nursing ethics. It would also provide a thicker account of nursing ethics than has been afforded thus far. Such research is dependent upon identifying, locating, accessing and, more importantly, sharing these resources. A number of important heritage ethics sources are identified so that researchers might better locate them. In addition, a bibliography of heritage ethics textbooks and a transcript of the earliest known journal article on nursing ethics in the US are provided. © The Author(s) 2015.

The objective of the study is to present and discuss attitudes, perceptions and opinions about sexism and gendered play in the massively multiplayer online roleplaying game (MMO), World of Warcraft. Through the use of an online survey which includes both multiple choice questions and open-ended questions, the research discusses the major themes and findings expressed by the World of Warcraft forum users (N = 294). The descriptive statistical findings presented are derived from the multiple choice questions. Within the sample, the results reveal that sexism is a contentious topic in the World of Warcraft community. 63.6% (n = 75) of female respondents reported experiencing sexism within the game. 27.5% (n = 44) of male respondents and 45.3% (n = 53) of female respondents believe that sexism is a problem in the game. Overall, 64.4% (n = 183) of the respondents reported sexism as a non-issue in the game. Themes surrounding the topic of sexism experienced within the game are presented based on frequency of homogenous responses. Based on the multiple choice questions and the open-ended questions, the research argues that sexism and gendered play in gaming should be studied more closely, as the results reveal that many MMO players are affected negatively by it.

Full Text Available Our research deals with the development of a new type of game-based learning environment: (MMORPG based on mixed reality, applied in the archaeological domain. In this paper, we propose a learning scenario that enhances players’ motivation thanks to individual, collaborative and social activities and that offers a continuous experience between the virtual environment and real places (archaeological sites, museum. After describing the challenge to a rich multidisciplinary approach involving both computer scientists and archaeologists, we present two types of game: multiplayer online role-playing games and mixed reality games. We build on the specificities of these games to make the design choices described in the paper. We also present three modular features we have developed to support independently three activities of the scenario. The proposed approach aims at raising awareness among people on the scientific approach in Archaeology, by providing them information in the virtual environment and encouraging them to go on real sites. We finally discuss the issues raised by this work, such as the tensions between the perceived individual, team and community utilities, as well as the choice of the entering point in the learning scenario (real or virtual for the players’ involvement in the game.

Research ethics in dissertations: ethical issues and complexity of reasoning.

Kjellström, S; Ross, S N; Fridlund, B

2010-07-01

Conducting ethically sound research is a fundamental principle of scientific inquiry. Recent research has indicated that ethical concerns are insufficiently dealt with in dissertations. To examine which research ethical topics were addressed and how these were presented in terms of complexity of reasoning in Swedish nurses' dissertations. Analyses of ethical content and complexity of ethical reasoning were performed on 64 Swedish nurses' PhD dissertations dated 2007. A total of seven ethical topics were identified: ethical approval (94% of the dissertations), information and informed consent (86%), confidentiality (67%), ethical aspects of methods (61%), use of ethical principles and regulations (39%), rationale for the study (20%) and fair participant selection (14%). Four of those of topics were most frequently addressed: the majority of dissertations (72%) included 3-5 issues. While many ethical concerns, by their nature, involve systematic concepts or metasystematic principles, ethical reasoning scored predominantly at lesser levels of complexity: abstract (6% of the dissertations), formal (84%) and systematic (10%). Research ethics are inadequately covered in most dissertations by nurses in Sweden. Important ethical concerns are missing, and the complexity of reasoning on ethical principles, motives and implications is insufficient. This is partly due to traditions and norms that discount ethical concerns but is probably also a reflection of the ability of PhD students and supervisors to handle complexity in general. It is suggested that the importance of ethical considerations should be emphasised in graduate and post-graduate studies and that individuals with capacity to deal with systematic and metasystematic concepts are recruited to senior research positions.

Ethics and Ethical Theories from an Islamic Perspective

AL-HASAN AL-AIDAROS

2013-12-01

Full Text Available With the collapse of many organizations, many researchers are increasingly paying attention to such phenomenon. But ethical issues are not always clear cut; there are many grey areas that need to be threaded with care by organizations. To determine whether an action or decision is ethically carried out, ethical theories, developed mainly by Western scholars, are the current theoretical framework organizations have at their disposal. Theories such as relativism, utilitarianism, egoism, deontology, the divine command theory, and the virtue ethics, are all products of Western understanding of what ethics are and how they are applicable to help one’s decision making process. Despite their utility, this paper intends to argue that the Western concepts and understanding of what ethics are limited and incomprehensive in explaining what is right and what is wrong. In its place, this paper argues that to understand the concepts of ethics that can extend beyond time and space. It has to be analysed from an Islamic perspective. Toward this purpose, this paper will compare and contrast between Islamic and Western perspectives of ethics, and highlight the main weaknesses and limitations of the former. Then, an argument on why Islam can provide the best understanding of ethics will be made.

Societal and ethical issues in human biomonitoring – a view from science studies

Directory of Open Access Journals (Sweden)

Bauer Susanne

2008-01-01

Full Text Available Abstract Background Human biomonitoring (HBM has rapidly gained importance. In some epidemiological studies, the measurement and use of biomarkers of exposure, susceptibility and disease have replaced traditional environmental indicators. While in HBM, ethical issues have mostly been addressed in terms of informed consent and confidentiality, this paper maps out a larger array of societal issues from an epistemological perspective, i.e. bringing into focus the conditions of how and what is known in environmental health science. Methods In order to analyse the effects of HBM and the shift towards biomarker research in the assessment of environmental pollution in a broader societal context, selected analytical frameworks of science studies are introduced. To develop the epistemological perspective, concepts from "biomedical platform sociology" and the notion of "epistemic cultures" and "thought styles" are applied to the research infrastructures of HBM. Further, concepts of "biocitizenship" and "civic epistemologies" are drawn upon as analytical tools to discuss the visions and promises of HBM as well as related ethical problematisations. Results In human biomonitoring, two different epistemological cultures meet; these are environmental science with for instance pollution surveys and toxicological assessments on the one hand, and analytical epidemiology investigating the association between exposure and disease in probabilistic risk estimation on the other hand. The surveillance of exposure and dose via biomarkers as envisioned in HBM is shifting the site of exposure monitoring to the human body. Establishing an HBM platform faces not only the need to consider individual decision autonomy as an ethics issue, but also larger epistemological and societal questions, such as the mode of evidence demanded in science, policy and regulation. Conclusion The shift of exposure monitoring towards the biosurveillance of human populations involves fundamental

Expressing epistemic stance in University lectures and TED talks: a contrastive corpu-based analysis

The aim of this study is to investigate the way academics convey epistemic stance (Conrad, Biber 2000 and build up their image as experts on the TED stage. To this purpose, a contrastive analysis was carried out comparing two corpora of spoken discourse, i.e. a corpus of TED talks and a corpus of MICASE university lectures from different disciplines. Although in both genres the speaker is an academic, both the communicative purpose and audience expectations differ substantially in the two contexts under scrutiny. This comparison highlights some distinguishing traits of TED talks and provides a better insight into this genre. Adopting a corpus-based approach, attention is first paid to the most recurrent epistemic lexical verbs (ELVs and to the use of first and second person pronouns in the two corpora. The qualitative analysis then focuses on similarities and differences in the discourse functions of the four most frequent ELVs (see, show, know, think and of their clusters when they combine with first and second person pronouns in the two corpora. Previous studies in the field of English for Academic Purposes (Rounds 1987; Fortanet 2004; Walsh 2004; Artiga León 2006; Bamford 2009 are referred to as a starting point to investigate a novel, unexplored pragmatic space (i.e. that of TED wherein academics accomplish purposes other than merely disseminating knowledge and training students, such as promoting their research and building up their image as experts.

(The Ethics of) Teaching Science and Ethics: A Collaborative Proposal.

Kabasenche, William P

2014-12-01

I offer a normative argument for a collaborative approach to teaching ethical issues in the sciences. Teaching science ethics requires expertise in at least two knowledge domains-the relevant science(s) and philosophical ethics. Accomplishing the aims of ethics education, while ensuring that science ethics discussions remain grounded in the best empirical science, can generally best be done through collaboration between a scientist and an ethicist. Ethics as a discipline is in danger of being misrepresented or distorted if presented by someone who lacks appropriate disciplinary training and experience. While there are exceptions, I take philosophy to be the most appropriate disciplinary domain in which to gain training in ethics teaching. Science students, who must be prepared to engage with many science ethics issues, are poorly served if their education includes a misrepresentation of ethics or specific issues. Students are less well prepared to engage specific issues in science ethics if they lack an appreciation of the resources the discipline of ethics provides. My collaborative proposal looks at a variety of ways scientists and ethicists might collaborate in the classroom to foster good science ethics education.

Expertise, Ethics Expertise, and Clinical Ethics Consultation: Achieving Terminological Clarity

Science.gov (United States)

Iltis, Ana S.; Sheehan, Mark

2016-01-01

The language of ethics expertise has become particularly important in bioethics in light of efforts to establish the value of the clinical ethics consultation (CEC), to specify who is qualified to function as a clinical ethics consultant, and to characterize how one should evaluate whether or not a person is so qualified. Supporters and skeptics about the possibility of ethics expertise use the language of ethics expertise in ways that reflect competing views about what ethics expertise entails. We argue for clarity in understanding the nature of expertise and ethics expertise. To be an ethics expert, we argue, is to be an expert in knowing what ought to be done. Any attempt to articulate expertise with respect to knowing what ought to be done must include an account of ethics that specifies the nature of moral truth and the means by which we access this truth or a theoretical account of ethics such that expertise in another domain is linked to knowing or being better at judging what ought to be done and the standards by which this “knowing” or “being better at judging” is determined. We conclude with a discussion of the implications of our analysis for the literature on ethics expertise in CEC. We do think that there are clear domains in which a clinical ethics consultant might be expert but we are skeptical about the possibility that this includes ethics expertise. Clinical ethics consultants should not be referred to as ethics experts. PMID:27256848

Large ethics.

Science.gov (United States)

Chambers, David W

2008-01-01

This essay presents an alternative to the traditional view that ethics means judging individual behavior against standards of right and wrong. Instead, ethics is understood as creating ethical communities through the promises we make to each other. The "aim" of ethics is to demonstrate in our own behavior a credible willingness to work to create a mutually better world. The "game" of ethics then becomes searching for strategies that overlap with others' strategies so that we are all better for intending to act on a basis of reciprocal trust. This is a difficult process because we have partial, simultaneous, shifting, and inconsistent views of the world. But despite the reality that we each "frame" ethics in personal terms, it is still possible to create sufficient common understanding to prosper together. Large ethics does not make it a prerequisite for moral behavior that everyone adheres to a universally agreed set of ethical principles; all that is necessary is sufficient overlap in commitment to searching for better alternatives.

Scepticism about the virtue ethics approach to nursing ethics.

Science.gov (United States)

Holland, Stephen

2010-07-01

Nursing ethics centres on how nurses ought to respond to the moral situations that arise in their professional contexts. Nursing ethicists invoke normative approaches from moral philosophy. Specifically, it is increasingly common for nursing ethicists to apply virtue ethics to moral problems encountered by nurses. The point of this article is to argue for scepticism about this approach. First, the research question is motivated by showing that requirements on nurses such as to be kind, do not suffice to establish virtue ethics in nursing because normative rivals (such as utilitarians) can say as much; and the teleology distinctive of virtue ethics does not transpose to a professional context, such as nursing. Next, scepticism is argued for by responding to various attempts to secure a role for virtue ethics in nursing. The upshot is that virtue ethics is best left where it belongs - in personal moral life, not professional ethics - and nursing ethics is best done by taking other approaches.

Epistemic Uncertainty in Evalustion of Evapotranspiration and Net Infiltration Using Analogue Meteorological Data

Energy Technology Data Exchange (ETDEWEB)

2006-09-01

Uncertainty is typically defined as a potential deficiency in the modeling of a physical process, owing to a lack of knowledge. Uncertainty can be categorized as aleatoric (inherent uncertainty caused by the intrinsic randomness of the system) or epistemic (uncertainty caused by using various model simplifications and their parameters). One of the main reasons for model simplifications is a limited amount of meteorological data. This paper is devoted to the epistemic uncertainty quantification involved in two components of the hydrologic balance-evapotranspiration and net infiltration for interglacial (present day), and future monsoon, glacial transition, and glacial climates at Yucca Mountain, using the data from analogue meteorological stations. In particular, the author analyzes semi-empirical models used for evaluating (1) reference-surface potential evapotranspiration, including temperature-based models (Hargreaves-Samani, Thornthwaite, Hamon, Jensen-Haise, and Turc) and radiation-based models (Priestly-Taylor and Penman), and (2) surface-dependent potential evapotranspiration (Penman-Monteith and Shuttleworth-Wallace models). Evapotranspiration predictions are then used as inputs for the evaluation of net infiltration using the semi-empirical models of Budyko, Fu, Milly, Turc-Pike, and Zhang. Results show that net infiltration ranges are expected to generally increase from the present-day climate to monsoon climate, to glacial transition climate, and then to the glacial climate. The propagation of uncertainties through model predictions for different climates is characterized using statistical measures. Predicted evapotranspiration ranges are reasonably corroborated against the data from Class A pan evaporometers (taking into account evaporation-pan adjustment coefficients), and ranges of net infiltration predictions are corroborated against the geochemical and temperature-based estimates of groundwater recharge and percolation rates through the unsaturated

In particular, the author analyzes semi-empirical models used for evaluating (1) reference-surface potential evapotranspiration, including temperature-based models (Hargreaves-Samani, Thornthwaite, Hamon, Jensen-Haise, and Turc) and radiation-based models (Priestly-Taylor and Penman), and (2) surface-dependent potential evapotranspiration (Penman-Monteith and Shuttleworth-Wallace models). Evapotranspiration predictions are then used as inputs for the evaluation of net infiltration using the semi-empirical models of Budyko, Fu, Milly, Turc-Pike, and Zhang. Results show that net infiltration ranges are expected to generally increase from the present-day climate to monsoon climate, to glacial transition climate, and then to the glacial climate. The propagation of uncertainties through model predictions for different climates is characterized using statistical measures. Predicted evapotranspiration ranges are reasonably corroborated against the data from Class A pan evaporometers (taking into account evaporation-pan adjustment coefficients), and ranges of net infiltration predictions are corroborated against the geochemical and temperature-based estimates of groundwater recharge and percolation rates through the unsaturated

Well-ordered science and Indian epistemic cultures: toward a polycentered history of science.

Science.gov (United States)

Ganeri, Jonardon

2013-06-01

This essay defends the view that "modern science," as with modernity in general, is a polycentered phenomenon, something that appears in different forms at different times and places. It begins with two ideas about the nature of rational scientific inquiry: Karin Knorr Cetina's idea of "epistemic cultures," and Philip Kitcher's idea of science as "a system of public knowledge," such knowledge as would be deemed worthwhile by an ideal conversation among the whole public under conditions of mutual engagement. This account of the nature of scientific practice provides us with a new perspective from which to understand key elements in the philosophical project of Jaina logicians in the seventh, eighth, and ninth centuries C.E. Jaina theory seems exceptionally well targeted onto two of the key constituents in the ideal conversation--the classification of all human points of view and the representation of end states of the deliberative process. The Buddhist theory of the Kathāvatthu contributes to Indian epistemic culture in a different way: by supplying a detailed theory of how human dialogical standpoints can be revised in the ideal conversation, an account of the phenomenon Kitcher labels "tutoring." Thus science in India has its own history, one that should be studied in comparison and contrast with the history of science in Europe. In answer to Joseph Needham, it was not 'modern science' which failed to develop in India or China but rather non-well-ordered science, science as unconstrained by social value and democratic consent. What I argue is that this is not a deficit in the civilisational histories of these countries, but a virtue.

Chinese insurance agents in "bad barrels": a multilevel analysis of the relationship between ethical leadership, ethical climate and business ethical sensitivity.

Zhang, Na; Zhang, Jian

2016-01-01

The moral hazards and poor public image of the insurance industry, arising from insurance agents' unethical behavior, affect both the normal operation of an insurance company and decrease applicants' confidence in the company. Contrarily, these scandals may demonstrate that the organizations were "bad barrels" in which insurance agents' unethical decisions were supported or encouraged by the organization's leadership or climate. The present study brings two organization-level factors (ethical leadership and ethical climate) together and explores the role of ethical climate on the relationship between the ethical leadership and business ethical sensitivity of Chinese insurance agents. Through the multilevel analysis of 502 insurance agents from 56 organizations, it is found that organizational ethical leadership is positively related to the organizational ethical climate; organizational ethical climate is positively related to business ethical sensitivity, and organizational ethical climate fully mediates the relationship between organizational ethical leadership and business ethical sensitivity. Organizational ethical climate plays a completely mediating role in the relationship between organizational ethical leadership and business ethical sensitivity. The integrated model of ethical leadership, ethical climate and business ethical sensitivity makes several contributions to ethics theory, research and management.

Cognitive Architecture and the Epistemic Gap: Defending Physicalism without Phenomenal Concepts

DEFF Research Database (Denmark)

Fazekas, Peter

2011-01-01

The novel approach presented in this paper accounts for the occurrence of the epistemic gap and defends physicalism against anti-physicalist arguments without relying on so-called phenomenal concepts. Instead of concentrating on conceptual features, the focus is shifted to the special...... characteristics of experiences themselves. To this extent, the account provided is an alternative to the Phenomenal Concept Strategy. It is argued that certain sensory representations, as accessed by higher cognition, lack constituent structure. Unstructured representations could freely exchange their causal...... to pose a serious problem for contemporary physicalism. I conclude that if those concepts which are related to the phenomenal character of conscious experience are special in any way, their characteristics are derivative of and can be accounted for in terms of the cognitive and representational features...

Medical ethics should not be subsumed under the classical types of ethical reasoning (e.g. Aristotle, Kant) nor the modern ethical versions of utilitarianism, deontology or ethics of discourse. All of them may contribute to medical ethics; but these should be goaled by general ethics in the meaning of how to lead a senseful life in its whole.

Examining the influence of actual-ideal self-discrepancies, depression, and escapism, on pathological gaming among massively multiplayer online adolescent gamers.

Science.gov (United States)

Li, Dongdong; Liau, Albert; Khoo, Angeline

2011-09-01

This study examined whether actual-ideal self-discrepancy (AISD) is related to pathological gaming through escapism as a means of reducing depression for adolescent massively multiplayer online gamers. A Discrepancy-reduction Motivation model of pathological video gaming was tested. A survey was conducted on 161 adolescent gamers from secondary schools. Two mediation effects were tested using path analysis: (a) depression would mediate the relationship between AISDs and escapism, and (b) escapism would mediate the relationship between depression and pathological gaming. Results support the hypotheses stated above. The indirect effects of both AISD and depression were significant on pathological gaming. AISD and escapism also had direct effects on pathological gaming. The present study suggests that pathological behaviors may be over-regulated coping strategies of approaching the ideal self and avoiding the actual self.

The Interplay between Real Money Trade and Narrative Structure in Massively Multiplayer Online Role-Playing Games

Byungchul Park

2017-01-01

Full Text Available A narrative structure is one of the main components to constitute the genre of Massively Multiplayer Online Role-Playing Games (MMORPGs. Meanwhile Real Money Trade (RMT enables a player to adjust an ex post level of challenge by skipping the narrative structure of a game. However, RMT may concurrently disturb a player who enjoys game following the narrative structure hierarchically. In pursuance of developing the knowledge about the relationship between RMT and the usage of MMORPG, we investigate the role of the strictness of predetermined narrative structure. We present the dual structure of societies to describe a player that arbitrarily decides to reside in a virtual society. Then we adopt the social nominalism to explain how individual motif of playing a game is expanded to the nature of game. Finally, we argue that a game with weakly predetermined narrative structure is more positively associated with RMT volume, since these games arouse a player’s sentiment of fun by relying more on their socially oriented motivation. With empirical evidence from the Korean MMORPGs market, we proved the hypothesis.

Epistemic Beliefs about Justification Employed by Physics Students and Faculty in Two Different Problem Contexts

Science.gov (United States)

Çağlayan Mercan, Fatih

2012-06-01

This study examines the epistemic beliefs about justification employed by physics undergraduate and graduate students and faculty in the context of solving a standard classical physics problem and a frontier physics problem. Data were collected by a think-aloud problem solving session followed by a semi-structured interview conducted with 50 participants, 10 participants at freshmen, seniors, masters, PhD, and faculty levels. Seven modes of justification were identified and used for exploring the relationships between each justification mode and problem context, and expertise level. The data showed that justification modes were not mutually exclusive and many respondents combined different modes in their responses in both problem contexts. Success on solving the standard classical physics problem was not related to any of the justification modes and was independent of expertise level. The strength of the association across the problem contexts for the authoritative, rational, and empirical justification modes fell in the medium range and for the modeling justification mode fell in the large range of practical significance. Expertise level was not related with the empirical and religious justification modes. The strength of the association between the expertise level and the authoritative, rational, experiential, and relativistic justification modes fell in the medium range, and the modeling justification mode fell in the large range of practical significance. The results provide support for the importance of context for the epistemic beliefs about justification and are discussed in terms of the implications for teaching and learning science.

Christian ethic of love and Hindu ethic of dharma: comparative analysis

OpenAIRE

Pavenkov Oleg Vladimirovich

2014-01-01

This article is devoted to comparative analysis of two ethic systems: Hindu ethic of dharma and Christian ethic of love. If Christian ethic is the ethic of love, love is in the center of Christian moral values, then Hindu ethic is an example of ethic of law. The moral behavior of gods and humans is determined by Karma and cycle of samsara, which is impossible in Christianity. However forgiveness, self-restraint, non-stealing, purity are common moral obligations for Christians and Hindus.

Nigerian Building Professionals’ Ethical Ideology and Perceived Ethical Judgement

Directory of Open Access Journals (Sweden)

John Oko Ameh

2010-10-01

Full Text Available In recent years, Nigeria is often cited in the international media in connection with corruption and other unethical practices. The professionals in the Nigerian building industry are not immune from the national trend in ethical erosion. Moral philosophy or ethical ideology has been used to explain individuals’ reasoning about moral issues and consequent behaviour. This study examines building industry professionals’ ethical ideologies with a view to understanding their ethical behaviour in professional practice.  In carrying out this investigation, building professionals in clients’ organisations, contracting and consultancy organisations within the industry were asked to respond to the Ethics Position Questionnaire (EPQ designed by Forsyth in order to determine their idealism and relativism level. Subsequently, they were classified into one of four groups, representing different ethical ideologies. The result indicates that the dominant ethical ideology of building industry professionals is situationism. The study predicts that the attitude of building industry professionals in practice, given the current socio-political and economic situation of Nigeria would possibly be unethical because of the extreme influence situational factors have on their behaviour. This finding is a bold step and necessary benchmark for resolving ethical issues within the industry and should be of interest to policy makers. It is also useful for intra professional ethical comparison.

Furthering the sceptical case against virtue ethics in nursing ethics.

Science.gov (United States)

Holland, Stephen

2012-10-01

In a recent article in this journal I presented a sceptical argument about the current prominence of virtue ethics in nursing ethics. Daniel Putman has responded with a defence of the relevance of virtue in nursing. The present article continues this discussion by clarifying, defending, and expanding the sceptical argument. I start by emphasizing some features of the sceptical case, including assumptions about the nature of sceptical arguments, and about the character of both virtue ethics and nursing ethics. Then I respond to objections of Putman's such as that, according to virtue ethics, virtue is relevant to the whole of a human life, including one's behaviour in a professional context; and that eudaimonia should be central in explaining and motivating a nurse's decision to enter the profession. Having argued that these objections are not compelling, I go on to discuss an interesting recent attempt to reassert the role of virtue ethics in the ethics of professions, including nursing. This centres on whether role-specific obligations - e.g. the obligations that arise for a moral agent qua lawyer or mother - can be accommodated in a virtue ethics approach. Sean Cordell has argued that the difficulty of accommodating role-specific obligations results in an 'institution-shaped gap' in virtue ethics. He suggests a way of meeting this difficulty that appeals to the ergon of institutions. I endorse the negative point that role-specific obligations elude virtue ethics, but argue that the appeal to the ergon of institutions is unsuccessful. The upshot is further support for scepticism about the virtue ethics approach to nursing ethics. I end by gesturing to some of the advantages of a sceptical view of virtue ethics in nursing ethics. © 2012 Blackwell Publishing Ltd.

Full Text Available Two aspects of Miranda Fricker’s book are criticised: the implicit assumption that ethical theory can solve fundamental problems in epistemology, and the excessive reliance on testimony as a fundamental source of knowledge. Against the former, it is argued that ethical theories are based on cultural prejudices to a higher extent than epistemological theories. Against the latter, argumentation is proposed as a more important epistemic practice than testimony.

Beyond a code of ethics: phenomenological ethics for everyday practice.

Science.gov (United States)

Greenfield, Bruce; Jensen, Gail M

2010-06-01

Physical therapy, like all health-care professions, governs itself through a code of ethics that defines its obligations of professional behaviours. The code of ethics provides professions with a consistent and common moral language and principled guidelines for ethical actions. Yet, and as argued in this paper, professional codes of ethics have limits applied to ethical decision-making in the presence of ethical dilemmas. Part of the limitations of the codes of ethics is that there is no particular hierarchy of principles that govern in all situations. Instead, the exigencies of clinical practice, the particularities of individual patient's illness experiences and the transformative nature of chronic illnesses and disabilities often obscure the ethical concerns and issues embedded in concrete situations. Consistent with models of expert practice, and with contemporary models of patient-centred care, we advocate and describe in this paper a type of interpretative and narrative approach to moral practice and ethical decision-making based on phenomenology. The tools of phenomenology that are well defined in research are applied and examined in a case that illustrates their use in uncovering the values and ethical concerns of a patient. Based on the deconstruction of this case on a phenomenologist approach, we illustrate how such approaches for ethical understanding can help assist clinicians and educators in applying principles within the context and needs of each patient.

Time perspective as a predictor of massive multiplayer online role-playing game playing.

Lukavska, Katerina

2012-01-01

This article focuses on the relationship between the time perspective (TP) personality trait and massive multiplayer online role-playing game (MMORPG) playing. We investigate the question of frequency of playing. The TP was measured with Zimbardo's TP Inventory (ZTPI), which includes five factors-past negative, past positive, present hedonistic, present fatalistic, and future. The study used data from 154 MMORPG players. We demonstrated that TP partially explained differences within a group of players with respect to the frequency of playing. Significant positive correlations were found between present factors and the amount of time spent playing MMORPGs, and significant negative correlation was found between the future factor and the time spent playing MMORPGs. Our study also revealed the influence of future-present balance on playing time. Players who scored lower in future-present balance variables (their present score was relatively high compared with their future score) reported higher values in playing time. In contrast to referential studies on TP and drug abuse and gambling, present fatalistic TP was demonstrated to be a stronger predictor of extensive playing than present hedonistic TP, which opened the question of motivation for playing. The advantage of our study compared with other personality-based studies lies in the fact that TP is a stable but malleable personality trait with a direct link to playing behavior. Therefore, TP is a promising conceptual resource for excessive playing therapy.

Ethical difficulties arise in healthcare practices. However, despite extensive research findings that demonstrate that most nurses are involved in recurrent ethical problems, institutions are not always able to effectively support nursing care professionals. The limited availability of ethics consultation services and traditional nursing training fails to meet the frequent and strong requests by health workers to support their ethical dilemmas. A questionnaire was administered to 374 nurses attending a specialist training and a lifetime learning programme in Italy. The respondents reported a high frequency of ethically sensitive situations, and they described the poor development of ethics support and a scarcity of ethics training programmes. The results suggest the importance of promoting ethics services that include consultation and ethics training. A need for systematic ethics educational activities was identified for improving the capacity of nurses to manage ethical issues in patient care.

'Wicked' ethics: Compliance work and the practice of ethics in HIV research.

Science.gov (United States)

Heimer, Carol A

2013-12-01

Using ethnographic material collected between 2003 and 2007 in five HIV clinics in the US, South Africa, Uganda, and Thailand, this article examines "official ethics" and "ethics on the ground." It compares the ethical conundrums clinic staff and researchers confront in their daily work as HIV researchers with the dilemmas officially identified as ethical issues by bioethicists and people responsible for ethics reviews and compliance with ethics regulations. The tangled relation between ethical problems and solutions invites a comparison to Rittel and Webber's "wicked problems." Official ethics' attempts to produce universal solutions often make ethics problems even more wickedly intractable. Ethics on the ground is in part a reaction to this intractability.

Full Text Available Through this study we seek to explore the concept of business ethics, in those aspects that we consider to be essential and concrete. We started from a few questions: Could the two concepts be compatible? If not, why not? If yes, could they be complementary? How real is the use of ethics in the profits of a business? How can be business ethics be exemplified and what principles are essential in doing business? How does the business environment react to the concept? These are some of the elements that will form the basis of this scientific study. Lately, business ethics has been becoming an increasingly popular topic. Set against the global economic crisis, the companies’ credibility could become a major concern. Business ethics also becomes a challenge for training and informing employees and employers, in order to make not only economical, but also ethical decisions regarding their profits. In the study we shall also address the ethical standards required in a business world interested in fundamental values that can make the difference in 21st century business. Also, according to a study conducted by the authors, we shall address the two most important ethical values that prove to be essential to a business.

Ethical aspects in tissue research: thematic analysis of ethical statements to the research ethics committee

Science.gov (United States)

2012-01-01

Background Many studies have been published about ethics committees and the clarifications requested about the submitted applications. In Finland, ethics committees require a separate statement on ethical aspects of the research in applications to the ethics committee. However, little is known about how researchers consider the ethical aspects of their own studies. Methods The data were collected from all the applications received by the official regional ethics committee in the Hospital District of Northern Savo during 2004–2009 (n = 688). These included a total of 56 studies involving research on tissue other than blood. The statements by the researchers about the ethics about their own research in these applications were analyzed by thematic content analysis under the following themes: recruitment, informed consent, risks and benefits, confidentiality and societal meaning. Results The researchers tended to describe recruitment and informed consent process very briefly. Usually these descriptions simply stated who the recruiter was and that written consent would be required. There was little information provided on the recruitment situation and on how the study recruiters would be informed. Although most of the studies were clinical, the possibility was hardly ever discussed that patients could fail to distinguish between care and research. Conclusion The written guidelines, available on the webpages of the ethics committee, do not seem to be enough to help researchers achieve this goal. In addition to detailed guidelines for researchers, investigators need to be taught to appreciate the ethical aspects in their own studies. PMID:22873761

Is mandatory research ethics reviewing ethical?

Science.gov (United States)

Dyck, Murray; Allen, Gary

2013-08-01

Review boards responsible for vetting the ethical conduct of research have been criticised for their costliness, unreliability and inappropriate standards when evaluating some non-medical research, but the basic value of mandatory ethical review has not been questioned. When the standards that review boards use to evaluate research proposals are applied to review board practices, it is clear that review boards do not respect researchers or each other, lack merit and integrity, are not just and are not beneficent. The few benefits of mandatory ethical review come at a much greater, but mainly hidden, social cost. It is time that responsibility for the ethical conduct of research is clearly transferred to researchers, except possibly in that small proportion of cases where prospective research participants may be so intrinsically vulnerable that their well-being may need to be overseen.
