This paper examines the legal and ethical aspects of traceback testing, a process in which patients who have been previously diagnosed with ovarian cancer are identified and offered genetic testing so that their family members can be informed of their genetic risk and can also choose to undergo testing. Specifically, this analysis examines the ethical and legal limits in implementing traceback testing in cases when the patient is deceased and can no longer consent to (...) genetic testing. (shrink)

Following a usage-based approach to language acquisition, lexically specific patterns are considered to be important building blocks for language productivity and feature heavily both in child-directed speech and in the early speech of children (Arnon, Inbal & Morten H. Christiansen. 2017. The role of multiword building blocks in explaining L1-L2 differences. Topics in Cognitive Science 9(3). 621–636; Tomasello, Michael. 2003. Constructing a language: A usage-based theory of language acquisition. Cambridge: Harvard University Press). In order to account for patterns, the (...) class='Hi'>traceback method has been widely applied in research on first language acquisition to test the hypothesis that children’s utterances can be accounted for on the basis of a limited inventory of chunks and partially schematic units (Lieven, Elena, Dorothé Salomo & Michael Tomasello. 2009. Two-year-old children’s production of multiword utterances: A usage-based analysis. Cognitive Linguistics 20(3). 481–508). In the current study, we applied the method to code-mixed utterances (n = 1,506) of three German-English bilingual children between 2 and 4 years of age to investigate individual differences in each child’s own inventory of patterns in relation to their input settings. It was shown that units such as I see X as in I see a Kelle ‘I see a trowel’ could be traced back to the child’s own previous productions. More importantly, we see that each child’s inventory of constructions draws heavily on multiword chunks that are strongly dependent on the children’s language input situations. (shrink)

Starting from the ‘Dewey Lectures’, Rawls presents his conception of justice within a contextualist framework, as an elaboration of the basic ideas embedded in the political culture of liberal-democratic societies. But how are these basic ideas to be justified? In this article, I reconstruct and criticize Rawls’s strategy to answer this question. I explore an alternative strategy, consisting of a genealogical argument of a pragmatic kind – the kind of argument provided by authors like Bernard Williams, Edward Craig and Miranda (...) Fricker. I outline this genealogical argument drawing on Rawls’s reconstruction of the origins of liberalism. Then, I clarify the conditions under which this kind of argument maintains vindicatory power. I claim that the argument satisfies these conditions and that pragmatic genealogy can thus partially vindicate the basic ideas of liberal-democratic societies. (shrink)

Assertion is fundamental to our lives as social and cognitive beings. Philosophers have recently built an impressive case that the norm of assertion is factive. That is, you should make an assertion only if it is true. Thus far the case for a factive norm of assertion been based on observational data. This paper adds experimental evidence in favor of a factive norm from six studies. In these studies, an assertion’s truth value dramatically affects whether people think it should be (...) made. Whereas nearly everyone agreed that a true assertion supported by good evidence should be made, most people judged that a false assertion supported by good evidence should not be made. The studies also suggest that people are consciously aware of criteria that guide their evaluation of assertions. Evidence is also presented that some intuitive support for a non-factive norm of assertion comes from a surprising tendency people have to misdescribe cases of blameless rule-breaking as cases where no rule is broken.

In exploring the nature of excess relative to a phenomenology of the limit, Testing the Limit claims that phenomenology itself is an exploration of excess. What does it mean that "the self" is "given"? Should we see it as originary; or rather, in what way is the self engendered from textual practices that transgress—or hover around and therefore within—the threshold of phenomenologial discourse? This is the first book to include Michel Henry in a triangulation with Derrida and Levinas and (...) the first to critique Levinas on the basis of his interpolation of philosophy and religion. Sebbah claims that the textual origins of phenomenology determine, in their temporal rhythms, the nature of the subjectivation on which they focus. He situates these considerations within the broader picture of the state of contemporary French phenomenology (chiefly the legacy of Merleau-Ponty), in order to show that these three thinkers share a certain "family resemblance," the identification of which reveals something about the traces of other phenomenological families. It is by testing the limit within the context of traditional phenomenological concerns about the appearance of subjectivity and ipseity that Derrida, Henry, and Levinas radically reconsider phenomenology and that French phenomenology assumes its present form.

Avia Pasternak argues that intentional citizens who are genuine participants of their state should share the liability for state wrongdoings. In real-world states, how prevalent is intentional citizenship? This commentary concerns the application of the theoretical model. I argue that there are two problems with Pasternak’s proposal of testing intentional citizenship in reality. First, the difficulty of distinguishing citizens’ ambiguous internal attitudes towards their citizenship is underestimated. Second, the objective aspect of citizens’ status in society, namely, the way they (...) are treated by their state, is more important than their subjective attitudes, but this aspect is neglected by Pasternak.

One approach to validating simulation models is to formally compare model outputs with independent data. We consider such model validation from the point of view of Frequentist statistics. A range of estimates and tests of goodness of fit have been advanced. We review these approaches, and demonstrate that some of the tests suffer from difficulties in interpretation because they rely on the null hypothesisHypothesis that the model is similar to the observationsObservations. This reliance creates two unpleasant possibilities, namely, a model (...) could be spuriously validated when dataData are too few, or inappropriately rejected when data are too many. Finally, these tests do not allow a principled declaration of what a reasonable level of difference would be considering the purposes to which the model will be put. We consider equivalence tests, and demonstrate that they do not suffer from the previously identified shortcomings. We provide two case studies to illustrate the claims of the chapter. (shrink)

In this paper, I propose to look closely at certain crucial aspects of the logic of Rawls' argument in Political Liberalism and related subsequent writings. Rawls' argument builds on the notion of comprehensiveness, whereby a doctrine encompasses the full spectrum of the life of its adherents. In order to show the mutual conflict and irreconcilability of comprehensive doctrines, Rawls needs to emphasise the comprehensiveness of doctrines, as their irreconcilability to a large extent emanates from that comprehensiveness. On the other hand, (...) in order to show the possibility and plausibility of the political liberal solution he needs to emphasise that most of these doctrines are reasonable: i.e., they are willing to cede a portion of their authority to political liberalism for the right reasons. Yet, if they are willing to cede a portion of their authority to a political conception they cannot be as comprehensive as we initially thought they were. All these elements highlight the tension in the argument itself. I suggest that many of these tensions can be removed by making Rawls' account more flexible. In this context I propose certain amendments to Rawls' account, which may overcome some of the tensions mentioned above. (shrink)

Disertační práce se zabývá problematikou připisování myšlení jiným entitám, a to pomocí imitační hry navržené v roce 1950 britským filosofem Alanem Turingem. Jeho kritérium, známé v dějinách filosofie jako Turingův test, je podrobeno detailní analýze. Práce popisuje nejen původní námitky samotného Turinga, ale především pozdější diskuse v druhé polovině 20. století. Největší pozornost je věnována těmto kritikám: Lucasova matematická námitka využívající Gödelovu větu o neúplnosti, Searlův argument čínského pokoje konstatující nedostatečnost syntaxe pro sémantiku, Blockův návrh na použití brutální síly pro (...) řešení imitační hry, Frenchova teorie subkognitivních informací a Michieho skepticismus ohledně možnosti umělého vědomí. Závěr práce zachycuje současný stav recepce Turingova testu a představuje pokusy o jeho praktickou realizaci, například v každoroční soutěži o Loebnerovu cenu. Autor práce zastává názor, že ani po více než šedesáti letech od uveřejnění Turingova paradigmatického eseje stále neexistují žádné vážné důvody pro zamítnutí jeho tvrzení. Tradiční komputační funkcionalismus možná není ideální teorií vysvětlující činnost myslí a jako slibnější se může jevit vývoj v neurálních vědách, ale Turingův test je přesto užitečným a snad i jediným nástrojem pro detekci inteligence u lidmi vytvořených strojů.

The historical sciences, such as geology, evolutionary biology, and archaeology, appear to have no means to test hypotheses. However, on closer examination, reasoning in the historical sciences relies upon regularities, regularities that can be tested. I outline the role of regularities in the historical sciences, and in the process, blur the distinction between the historical sciences and the experimental sciences: all sciences deploy theories about the world in their investigations.

Ducklings were placed either singly or in pairs on a platform at two different heights. Both height and pairing influenced performance: More ducklings descended from the platform at low heights, and more single ducklings descended than paired ducklings. The social factor, pairing, made behavior more cautious and decreased the number of distress calls. A similar trend for pairing to influence performance was shown on the visual cliff. Without its peers, the duckling is a distressed animal. Previous careless behavior by ducklings (...) on the visual cliff may be ascribed to testing the ducklings outside their normal social environment. (shrink)

Which animals have conscious experiences? Many different, diverse and unrelated behaviors and cognitive capacities have been proposed as tests of the presence of consciousness in an animal. It is unclear which of these tests, if any, are valid. To remedy this problem, I develop a list consisting of eight desiderata which can be used to assess putative tests of animal consciousness. These desiderata are based either on detailed analogies between consciousness-linked human behavior and non-human behavior, on theories of consciousness or (...) on methods from human consciousness science. If a test or set of tests satisfies more of these desiderata, passing it provides stronger evidence of consciousness. Moreover, one can design future tests of animal consciousness with the intention of satisfying these desiderata to ensure their evidential strength. (shrink)

Through a discussion of how the inventive practices of farm animal genomics interact with animal disease and food risk, this paper aims to expand our notion of what constitute the social dimensions of animal genomics, and why attention to animals and the contemporary issues surrounding them can offer us insights into genomics in general. Through a case study of the circumstances surrounding the invention of the DNA TraceBack technology in the midst of the BSE crisis, I argue that, rather (...) than just examining genomics in and of itself, we should follow the inventions of genomics and their inseparable informational material environments. Then we can see the need for a social science approach that is more attentive to the inseparability of politics and science at the material level and can invent new, more inclusive, problems and research questions.

The accelerating advances in the fields of neuroscience, artificial intelligence, and robotics have been garnering interest and raising new philosophical, ethical, or practical questions that depend on whether or not there may exist a scientific method of probing consciousness in machines. This paper provides an analytic review of the existing tests for machine consciousness proposed in the academic literature over the past decade, and an overview of the diverse scientific communities involved in this enterprise. The tests put forward in their (...) work typically fall under one of two grand categories: architecture and behaviour. Each category has its strengths and weaknesses. Architecture tests' main advantage is that they could apparently test for qualia, a feature that has been receiving increasing attention in recent years. Behaviour tests are more synthetic and more practicable, but give a stronger role to ex post human interpretation of behaviour. We show how some disciplines and places have affinities towards certain type of tests, and which tests are more influential according to scientometric indicators. (shrink)

In ‘What Has Philosophy to Learn from Tort Law?’, Bernard Williams reaffirms J. L. Austin’s suggestion that philosophy might learn from tort law ‘the difference between practical reality and philosophical frivolity’. Yet while Austin regarded tort law as just another repository of time-tested concepts, on a par with common sense as represented by a dictionary, Williams argues that ‘the use of certain ideas in the law does more to show that those ideas have strength than is done by the mere (...) fact that they are part of the currency of common sense’. But what does it mean to show that ideas or concepts ‘have strength’? How does conceptual strength relate to the distinction between practical reality and philosophical frivolity? And what special features of the law are supposed to make it a better test of conceptual strength than common sense? In this chapter, I reconstruct and develop Williams’s answers to these questions. I show why Williams believes that we need to test the concepts forming the currency of common sense against practical reality as embodied by legal practice; I identify seven features of tort law that make it particularly suitable to act as such a test; I distinguish three respects in which concepts can show strength, and unpack Williams’s metaphor of microwave-resistant concepts: concepts capable of holding and presenting material for intense critical scrutiny without succumbing to it themselves; lastly, I show how philosophy can learn to identify systematically weak concepts, and the limits of otherwise valuable concepts, by considering which concepts fail the test.

Inference to the Best Explanation has become the subject of a livelydebate in the philosophy of science. Scientific realists maintain, while scientificantirealists deny, that it is a compelling rule of inference. It seems that anyattempt to settle this debate empirically must beg the question against theantirealist. The present paper argues that this impression is misleading. A methodis described that, by combining Glymour's theory of bootstrapping and Hacking'sarguments from microscopy, allows us to test IBE without begging any antirealistissues.

-/- For all that digital methods—including network visualization, text analysis, and others—have begun to show extensive promise in philosophical contexts, a tension remains between two uses of those tools that have often been taken to be incompatible, or at least to engage in a kind of trade-off: the discovery of new hypotheses and the testing of already-formulated positions. This paper presents this basic distinction, then explores ways to resolve this tension with the help of two interdisciplinary case studies, taken (...) from preregistration in contemporary science and the debate over whig history in the history of science. These case studies, the paper argues, refocus our attention from a mutually exclusive testing/discovery binary to the relationship between our background data or philosophical views and the empirical generalizations that we might draw from the data. Finally, it develops a set of three challenges for philosophers and corresponding avenues for future work that will, it is hoped, allow us to better justify our use of these methods. (shrink)

In the 70 years since Alan Turing’s ‘Computing Machinery and Intelligence’ appeared in Mind, there have been two widely-accepted interpretations of the Turing test: the canonical behaviourist interpretation and the rival inductive or epistemic interpretation. These readings are based on Turing’s Mind paper; few seem aware that Turing described two other versions of the imitation game. I have argued that both readings are inconsistent with Turing’s 1948 and 1952 statements about intelligence, and fail to explain the design of his game. (...) I argue instead for a response-dependence interpretation. This interpretation has implications for Turing’s view of free will: I argue that Turing’s writings suggest a new form of free will compatibilism, which I call response-dependence compatibilism. The philosophical implications of rethinking Turing’s test go yet further. It is assumed by numerous theorists that Turing anticipated the computational theory of mind. On the contrary, I argue, his remarks on intelligence and free will lead to a new objection to computationalism. (shrink)

The “testing effect” refers to the finding that after an initial study opportunity, testing is more effective for long‐term retention than restudying. The testing effect seems robust and is a finding from the field of cognitive science that has important implications for education. However, it is unclear whether this effect also applies to the acquisition of problem‐solving skills, which is important to establish given the key role problem solving plays in, for instance, math and science education. Worked (...) examples are an effective and efficient way of acquiring problem‐solving skills. Forty students either only studied worked examples (SSSS) or engaged in testing after studying an example by solving an isomorphic problem (STST). Surprisingly, results showed equal performance in both conditions on an immediate retention test after 5 min, but the SSSS condition outperformed the STST condition on a delayed retention test after 1 week. These findings suggest the testing effect might not apply to acquiring problem‐solving skills from worked examples. (shrink)

In my previous thinking about the considerations that go under the heading of the “expressivist argument,” I have been fascinated chiefly by two of its features: its semantic commitments and its independence from disputes about the moral standing of fetuses. Abortions prompted by prenatal testing are undertaken because of indications that the fetus has physical features that would be configured as disabilities in the social world into which it would otherwise emerge. The expressivist argument's allegation, as I have understood (...) it, is that abortions so motivated convey semantic content—“send a message”—to people who are currently living with disabilities that is somehow insulting, hateful, dismissive, or disparaging. It is thus uncontroversial moral subjects who are wronged, not—or, at least, not necessarily—the aborted fetuses. So far as this argument goes, a person might hold strongly pro-choice views about abortion generally and still object to “selective” abortions. (shrink)

The Turing Test is one of the most disputed topics in artificial intelligence, philosophy of mind, and cognitive science. This paper is a review of the past 50 years of the Turing Test. Philosophical debates, practical developments and repercussions in related disciplines are all covered. We discuss Turing's ideas in detail and present the important comments that have been made on them. Within this context, behaviorism, consciousness, the 'other minds' problem, and similar topics in philosophy of mind are discussed. We (...) also cover the sociological and psychological aspects of the Turing Test. Finally, we look at the current situation and analyze programs that have been developed with the aim of passing the Turing Test. We conclude that the Turing Test has been, and will continue to be, an influential and controversial topic. -/- (This paper was reprinted in: The Turing Test: The Elusive Standard of Artificial Intelligence, J.

Which systems/organisms are conscious? New tests for consciousness (‘C-tests’) are urgently needed. There is persisting uncertainty about when consciousness arises in human development, when it is lost due to neurological disorders and brain injury, and how it is distributed in nonhuman species. This need is amplified by recent and rapid developments in artificial intelligence (AI), neural organoids, and xenobot technology. Although a number of C-tests have been proposed in recent years, most are of limited use, and currently we have no (...) C-tests for many of the populations for which they are most critical. Here, we identify challenges facing any attempt to develop C-tests, propose a multidimensional classification of such tests, and identify strategies that might be used to validate them. (shrink)

_The Test Drive_ deals with the war perpetrated by highly determined reactionary forces on science and research. How does the government at once promote and prohibit scientific testing and undercut the importance of experimentation?

Despite the widespread use of key concepts of the Neyman–Pearson (N–P) statistical paradigm—type I and II errors, significance levels, power, confidence levels—they have been the subject of philosophical controversy and debate for over 60 years. Both current and long-standing problems of N–P tests stem from unclarity and confusion, even among N–P adherents, as to how a test's (pre-data) error probabilities are to be used for (post-data) inductive inference as opposed to inductive behavior. We argue that the relevance of error probabilities (...) is to ensure that only statistical hypotheses that have passed severe or probative tests are inferred from the data. The severity criterion supplies a meta-statistical principle for evaluating proposed statistical inferences, avoiding classic fallacies from tests that are overly sensitive, as well as those not sensitive enough to particular errors and discrepancies. Introduction and overview 1.1 Behavioristic and inferential rationales for Neyman–Pearson (N–P) tests 1.2 Severity rationale: induction as severe testing 1.3 Severity as a meta-statistical concept: three required restrictions on the N–P paradigm Error statistical tests from the severity perspective 2.1 N–P test T(): type I, II error probabilities and power 2.2 Specifying test T() using p-values Neyman's post-data use of power 3.1 Neyman: does failure to reject H warrant confirming H?

Historically, a great deal of attention has been addressed to the question of what it would take to test experimentally the metrical structure of spacetime. Arguably, however, consideration of this question has been at the expense of comparable investigations into what it would take to test other structural features of spacetime. In this article, we critique and expand substantially upon an article by Hadley (Hadley in Class Quantum Gravity, 19:4565–4571, 2002), which constitutes one of the best-known paper-length studies of what (...) it would take to test the orientability of spacetime. In so doing, we seek to clarify a number of matters which remain unclear in the wake of Hadley’s article, thereby allowing the literature on this topic to progress. More positively, we also present, compare, and evaluate a number of other potential approaches to testing the orientability of spacetime which have arisen in the recent physics literature. (shrink)

Recent experimental work on “natural” kind terms has shown evidence of both descriptive and nondescriptive reference determination. This has led some to propose ambiguity or hybrid theories, as opposed to traditional description and causal‐historical theories of reference. Many of those experiments tested theories against referential intuitions. We reject this method, urging that reference should be tested against usage, preferably by elicited production. Our tests of the usage of a biological kind term confirm that there are indeed both descriptive and causal‐historical (...) elements to the reference determination of some natural kind terms. We argue that to accommodate our results and earlier ones, we should abandon the common assumption that any one theory of reference fits all natural kind terms. Rather, it is likely that some terms are descriptive, some causal‐historical, some ambiguous, and some hybrid. This substantive conclusion is accompanied by a methodological one. Our experiments, like some earlier ones, found participants contradicting both each other and themselves. We argue that these contradictions indicate a lack of linguistic competence with the term. We conclude that these experiments have been faulty, because they test terms that are novel to participants and/or use fantastical vignettes. We provide some suggestions for future research.

A new Evidence Test is applied to the problem of testing whether two Poisson random variables are dependent. The dependence structure is that of Holgate’s bivariate distribution. These bivariate distribution depends on three parameters, 0 < theta_1, theta_2 < infty, and 0 < theta_3 < min(theta_1, theta_2). The Evidence Test was originally developed as a Bayesian test, but in the present paper it is compared to the best known test of the hypothesis of independence in a frequentist framework. It (...) is shown that the Evidence Test is considerably more powerful when the correlation is not too close to zero, even for small samples. (shrink)

This study tests an integrative model of corporate political action, the filter model, based on the behavioral theory of the firm. The filter model posits that external political, economic, and industry environments are mediated by organizational structures and resources to affect a firm’s political actions. The authors rate the filter model’s predictive power against that of an economic-based direct-effects model by examining the efforts of about 1,100 U.S.-domiciled manufacturing firms to influence trade policy. LISREL analysis demonstrates that the integrative filter (...) model provides a superior explanation of corporate political action. (shrink)

Complex constraints like conditionals ('If A, then B') and probabilistic constraints ('The probability that A is p') pose problems for Bayesian theories of learning. Since these propositions do not express constraints on outcomes, agents cannot simply conditionalize on the new information. Furthermore, a natural extension of conditionalization, relative information minimization, leads to many counterintuitive predictions, evidenced by the sundowners problem and the Judy Benjamin problem. Building on the notion of a `paradigm shift' and empirical research in psychology and economics, I (...) argue that the model of hypothesis testing can explain how people learn complex, theory-laden propositions like conditionals and probability constraints. Theories are formalized as probability distributions over a set of possible outcomes and theory change is triggered by a constraint which is incompatible with the initial theory. This leads agents to consult a higher order probability function, or a 'prior over priors,' to choose the most likely alternative theory which satisfies the constraint. The hypothesis testing model is applied to three examples: learning a simple probabilistic constraint involving coin bias, the sundowners problem for conditional learning, and the Judy Benjamin problem for learning conditional probability constraints.

This paper advances the research on personalization of political communication by investigating whether this process of focusing on politicians instead of political issues plays a role on Twitter. Results of a content analysis of 5,530 tweets posted in the run-up to the German federal election provide evidence that Twitter communication refers more often to politicians than to issues. However, tweets containing personal characteristics about political leaders play only a marginal role. When distinguishing among different groups of actors on Twitter (journalists, (...) politicians, citizens), we find that citizens focus more on candidates than do journalists or politicians. Investigating the impact of a televised debate on Twitter communication, we observe that this person-centered event puts the focus on individual politicians instead of issues. (shrink)

Genetic testing has historically been performed in the context of chronic disease and cancer diagnostics. The timelines for these tests are typically measured in days or weeks, rather than in minutes. As such, the concept that genetic information might be generated and then used to alter management in the acute setting has, thus far, not been feasible. However, recent advances in genetic technologies have the potential to allow genetic information to be generated significantly quicker. The m.1555A>G genetic variant is (...) present in one in 500 individuals and predisposes to profound hearing loss following the administration of aminoglycoside antibiotics. These antibiotics are used frequently in cases of neonatal sepsis and it is estimated that approximately 180 neonates in the UK are at risk of antibiotic induced hearing loss each year because of this genetic change. Knowledge of this variant in the acute setting would allow clinicians to prescribe alternative antibiotics. The Pharmacogenetics to Avoid Loss of Hearing study will implement a genetic point of care test for the m.1555A>G variant within two major UK based neonatal intensive care units. This represents the first trial of a genetic POCT aimed at altering management in the acute setting. This round table discussion outlines the novel ethical issues faced in the development of this trial and the legal barriers to implementation. We ask five stakeholders to provide their opinions on this trial and their perspectives on the concept of genetic testing in the acute setting.Trial registration numberISRCTN-13704894. (shrink)

Traditionally, two main rationales for the provision of prenatal testing and screening are identified: the expansion of women’s reproductive choices and the reduction of the burden of disease on society. With the number of prenatal tests available and the increasing potential for their widespread use, it is necessary to examine whether the reproductive autonomy model remains useful in upholding the autonomy of pregnant women or whether it allows public health considerations and even eugenic aims to be smuggled in under (...) the smokescreen of autonomy. In this article I argue that if we are serious about upholding women’s autonomy in the context of prenatal testing, what is needed is a model based on a more robust conception of reproductive autonomy, such as the one defended by Josephine Johnston and Rachel Zacharias as ‘reproductive autonomy worth having’. While Johnston and Zacharias put forward a basic outline of this conception, I apply it to the specific case of prenatal testing and show how it responds to objections levelled against the reproductive autonomy model. I argue that adopting this kind of conception is necessary to avoid fundamental challenges to women’s autonomy when it comes to prenatal screening and testing. (shrink)

"In these essays, health care professionals, scholars, and members of the disability community debate the implications of prenatal testing for people with disabilitties and for parent-child relationships generally."--Cover.

TEST is a novel taxonomy of knowledge representations based on three distinct hierarchically organized representational features: Tropism, Embodiment, and Situatedness. Tropic representational features reflect constraints of the physical world on the agent's ability to form, reactivate, and enrich embodied (i.e., resulting from the agent's bodily constraints) conceptual representations embedded in situated contexts. The proposed hierarchy entails that representations can, in principle, have tropic features without necessarily having situated and/or embodied features. On the other hand, representations that are situated and/or embodied (...) are likely to be simultaneously tropic. Hence, although we propose tropism as the most general term, the hierarchical relationship between embodiment and situatedness is more on a par, such that the dominance of one component over the other relies on the distinction between offline storage versus online generation as well as on representation-specific properties.
