Although other animals can make simple tools, the expanded and complex material culture of humans is unprecedented in the animal kingdom. Tool making is a slow and late-developing ability in humans, and preschool children find making tools to solve problems very challenging. This difficulty in tool making might be related to the lack of familiarity with the tools and may be overcome by children's long term perceptual-motor knowledge. Thus, in this study, the effect of tool familiarity on tool making was (...) investigated with a task in which 5-to-6-year-old children (n = 75) were asked to remove a small bucket from a vertical tube. The results show that children are better at tool making if the tool and its relation to the task are familiar to them (e.g., soda straw). Moreover, we also replicated the finding that hierarchical complexity and tool making were significantly related. Results are discussed in light of the ideomotor approach. (shrink)

Ekonomik faaliyetlerde kullanılan ürünlerin tümü emtia olarak adlandırılmaktadır. Emtia piyasasına yapılan yatırımları üretim ekonomisi ile ilişkilidir. Üretimin arttığı dönemlerde ülkelerde ham made ihtiyacı ortaya çıkmaktadır. Ortaya çıkan talep artışı emtia fiyatlarını artırmaktadır. Özelliklerde kriz dönemlerinde farklı olarak talep miktarı azalmaktadır. Kriz dönemlerinde talep miktarının azalışı emtia fiyatlarında oynak düşüşlere neden olmaktadır. Gümüş hem sanayide hem de yatırım amacıyla kullanılan değerli bir metaldir. Gümüş metali özellikle son yıllarda yenilebilir enerji için bir ham made durumuna gelmiştir. Bu duruma bağlı olarak gümüş talebinde (...) artışlar gözlenmiştir. Fakat, Covid-19 süreci başlangıcı itibari ile gümüş talebini sınırlamıştır. Özellik Covid-19 pandemi döneminde birçok ürünün fiyatlarında oynaklıklar görülmüştür. Gümüş ons fiyatında pandeminin ilanı itibari ile keskin bir düşüş görülmüştür. Fiyatlarda gözlenen düşüş hızlı bir toparlanma ile birlikte yerini büyük ölçekli artış hareketine bırakmıştır. Finansal varlıklardaki yatırımcıların Covid-19 dönemindeki temel endişesi yatırım portföylerini piyasadaki olumsuz hareketlerden korunmasıdır. Covid-19 salgınında yaşanan toparlanma ile birlikte yatırımcılar gümüş metalini güvenli liman olarak görmüşlerdir. Bu çalışmada, gümüş piyasasındaki balonun varlığı araştırmak üzere pandeminin başlangıç tarihi olan 11 Mart 2020 tarihi ile 30 Agustos 2021 arasındaki günlük ons gümüş fiyatı GSADF yöntemi ile incelenmiştir. Çalışmada yapılan analiz sonucunda 2020 yılı üçüncü çeyreğinde birden çok fiyat balonu oluştuğu gözlenmiştir. (shrink)

In this paper, I identify a theoretical and political role for ‘white ignorance’, present three alternative accounts of white ignorance, and assess how well each fulfils this role. On the Willful Ignorance View, white ignorance refers to white individuals’ willful ignorance about racial injustice. On the Cognitivist View, white ignorance refers to ignorance resulting from social practices that distribute faulty cognitive resources. On the Structuralist View, white ignorance refers to ignorance that (1) results as part of a social process that (...) systematically gives rise to racial injustice, and (2) is an active player in the process. I argue that, because of its greater power and flexibility, the Structuralist View better explains the patterns of ignorance that we observe, better illuminates the connection to white racial domination, and is overall better suited to the project of ameliorating racial injustice. As such, the Structuralist View should be preferred. (shrink)

The paper investigates whether it is plausible to hold the late stage demented criminally responsible for past actions. The concern is based on the fact that policy makers in the United States and in Britain are starting to wonder what to do with prison inmates in the later stages of dementia who do not remember their crimes anymore. The problem has to be expected to become more urgent as the population ages and the number of dementia patients increases. This paper (...) argues that the late-stage demented should not be punished for past crimes. Applicable theories of punishment, especially theories with an appropriate expressivist, or communicative element, fail to justify the imprisonment of the late-stage demented. Further imprisonment would require a capacity for comprehension on the part of the punished, and, under certain narrowly specified conditions, even a capacity to be at least in principle capable of recalling the crime again.

There is a widespread consensus that a commodification of body parts is to be prevented. Numerous policy papers by international organizations extend this view to the blood supply and recommend a system of uncompensated volunteers in this area—often, however, without making the arguments for this view explicit. This situation seems to indicate that a relevant source of justified worry or unease about the blood supply system has to do with the issue of commodification. As a result, the current health minister (...) of Ontario is proposing a ban on compensation even for blood plasma—despite the fact that Canada can only generate 30 % of the plasma needed for fractionation into important plasma protein products and has to purchase the rest abroad. In the following, I am going to suggest a number of alternative perspectives on the debate in order to facilitate a less dogmatic and more differentiated debate about the matter. Especially in light of the often over-simplified notions of altruism and commodification, I conclude that the debate has not conclusively established that it would be morally objectionable to provide blood plasma donors with monetary compensation or with other forms of explicit social recognition as an incentive. This is especially true of donations for fractionation into medicinal products by profit-oriented pharmaceutical companies. (shrink)

Bettina Schöne-Seifert and Marco Stier present a host of detailed and intriguing arguments to the effect that potentiality arguments have to be viewed as outdated due to developments in stem cell research, in particular the possibility of re-setting the development potential of differentiated cells, such as skin cells. However, their argument leaves them without an explanation of the intuitive difference between skin cells and human beings, which seems to be based on the assumption that a skin cell is merely part (...) of a human organism, while an embryo is at some point a human organism. An appropriately designed concept of the human organism can explain the difference, but also has the potential of re-dividing the argumentative landscape along familiar lines. (shrink)

The current ethical and regulatory framework for research is often charged with burdening investigators and impeding socially valuable research. To address these concerns, a growing number of research ethicists argue that informed consent should be adapted to the risks of research participation. This would require less rigorous consent standards in low-risk research than in high-risk research. However, the current discussion is restricted to cases of research in which the risks of research participation are outweighed by the potential clinical benefits for (...) the individual research participant. Furthermore, current proposals do not address the worry that risk-adapted informed consent may result in enrolling participants into research without their autonomous authorization. In this paper, we show how the standard view of informed consent – consent as autonomous authorization – can be adapted to risk even when the research does not have a favourable risk-benefit profile for the participant. Our argument has two important implications: first, it implies that current and proposed consent standards are not adequately calibrated to risk and, second, that consent standards also need to be adapted to factors other than risk.

Amongst invertebrates, molluscs show great variability in their nervous system ranging from primitive arrangement in Chitons to the complex mass of fused ganglia forming the ‘brain’ of cephalopods. Most of the effector organs used for pharmacological or physiological experiments. The neurosecretory cells (NSCs) with their combination of neuronal and glandular capabilities are perfectly suited to translate a neuronal input into the hormonal output best suited to long-term process. In this capacity, the NSCs may produce hormones, which act directly upon the (...) peripheral target or it may exert its effect indirectly by influencing the activity of other non-neural, endocrine organs. Neurosecretory cells have been detected in the cerebral, pedal and visceral ganglia of Lamellidens corrianus. The distribution and biology of freshwater bivalve like Lamellidens corrianus is influenced by local ecological factors (like temperature, pH, inorganic salts, type of soil etc.), water flow system and presence of micro-organisms, teleost fishes and seasonal variations in these parameters. Nitrogenous excretory changes which include ammonia in these molluscs is also influenced by these local ecological factors in which temperature is plays very crucial role. It is well known fact that the high stress conditions during drought or severe winter conditions have been conquered by several lineage of gastropods and sand bivalves and their ability to enter the resistant or dormant stages (low food) protein catabolism increased. Present investigation deals with the oxygen consumption and ammonia excretion ratio of these freshwater pelecypode Lamellidens corrianus. Study on Lemellidens corrianus directed in understanding the different behavioral and physiological aspects after cerebral ganglia removal and injection of their extracts revealed significant changes during summer (April-May).

Are words like ‘woman’ or ‘man’ sex terms that we use to talk about biological features of individuals? Are they gender terms that we use to talk about non-biological features e.g. social roles? Contextualists answer both questions affirmatively, arguing that these terms concern biological or non-biological features depending on context. I argue that a recent version of contextualism from Jennifer Saul that Esa Diaz-Leon develops doesn't exhibit the right kind of flexibility to capture our theoretical intuitions or moral and political (...) practices concerning our uses of these words. I then float the view that terms like 'woman' or 'man' are polysemous, arguing that it makes better sense of the significance of some forms of criticisms of mainstream gender ideology. (shrink)

Experimental philosophers have gathered impressive evidence for the surprising conclusion that philosophers' intuitions are out of step with those of the folk. As a result, many argue that philosophers' intuitions are unreliable. Focusing on the Knobe Effect, a leading finding of experimental philosophy, we defend traditional philosophy against this conclusion. Our key premise relies on experiments we conducted which indicate that judgments of the folk elicited under higher quality cognitive or epistemic conditions are more likely to resemble those of the (...) philosopher. We end by showing how our experimental findings can help us better understand the Knobe Effect. (shrink)

In this paper, we propose a framework for fostering argumentative skills in a systematic way in Philosophy and Ethics classes. We start with a review of curricula and teaching materials from the German-speaking world to show that there is an urgent need for standards for the teaching and learning of argumentation. Against this backdrop, we present a framework for such standards that is intended to tackle these difficulties. The spiral-curricular model of argumentative competences we sketch helps teachers introduce the relevant (...) concepts and skills to students early on in their school career. The focus is on secondary schools, but the proposal can also be of use for learning and teaching in universities, especially in introductory classes. (shrink)

This study asserts that W.V.O. Quine’s eliminative philosophical gaze into mereological composition affects inevitably his interpretations of composition theories of ontology. To investigate Quine’s property monism from the account of modal eliminativism, I applied to his solution for the paradoxes of de re modalities’ . Because of its vital role to figure out how dispositions are encountered by Quine, it was significantly noted that the realm of de re modalities doesn’t include contingent and impossible inferences about things. Therefore, for him, (...) all the intrinsic forces and elements of entities such as powers and causal or teleological dispositions for ontology demand to be seen necessarily as bound variables from a monist perspective. Although his denial of analyticity and the elimination of dispositional field of ontology, S. Mumford criticizes the monist perspective of Quine’s paradoxical approach to superveniences. Because superveniences create problems while determining type-type identities from a monist mereological perspective. It is observed that Quine faces with a reduction again in terms of his dispositional monism despite his critiques to repulse vagueness from the ontology in his well-known article Two Dogmas of Empiricism. -/- .

Ethicists struggle to take reductive views seriously. They also have trouble conceiving of some supervenience failures. Understanding why provides further evidence for a kind of hybrid view of normative concept use.

Political legitimacy is best understood as one type of a broader notion, which I call institutional legitimacy. An institution is legitimate in my sense when it has the right to function. The right to function correlates to a duty of non-interference. Understanding legitimacy in this way favorably contrasts with legitimacy understood in the traditional way, as the right to rule correlating to a duty of obedience. It helps unify our discourses of legitimacy across a wider range of practices, especially including (...) the many evaluations we increasingly make of international institutions of various sorts, but also including domestic institutions.

Standard accounts of civil disobedience include nonviolence as a necessary condition. Here I argue that such accounts are mistaken and that civil disobedience can include violence in many aspects, primarily excepting violence directed at other persons. I base this argument on a novel understanding of civil disobedience: the special character of the practice comes from its combination of condemnation of a political practice with an expressed commitment to the political. The commitment to the political is a commitment to engaging with (...) others as co-members in the on-going political project of living together. I show how such an understanding of civil disobedience is superior to the Rawlsian strain of thought, which focuses on fidelity to law. Rawls was concerned with civil disobedience solely in the context of overriding political obligation. The project of characterizing a contestatory political practice that can be distinguished and used in a wider variety of contexts than Rawls is concerned with, including under illegitimate regimes, beyond the nation-state, or on behalf of anarchism, requires a different understanding of civil disobedience.

The democratic boundary problem raises the question of who has democratic participation rights in a given polity and why. One possible solution to this problem is the all-affected principle, according to which a polity ought to enfranchise all persons whose interests are affected by the polity’s decisions in a morally significant way. While AAP offers a plausible principle of democratic enfranchisement, its supporters have so far not paid sufficient attention to economic participation rights. I argue that if one commits oneself (...) to AAP, one must also commit oneself to the view that political participation rights are not necessarily the only, and not necessarily the best, way to protect morally weighty interests. I also argue that economic participation rights raise important worries about democratic accountability, which is why their exercise must be constrained by a number of moral duties. (shrink)

It is becoming more common that the decision-makers in private and public institutions are predictive algorithmic systems, not humans. This article argues that relying on algorithmic systems is procedurally unjust in contexts involving background conditions of structural injustice. Under such nonideal conditions, algorithmic systems, if left to their own devices, cannot meet a necessary condition of procedural justice, because they fail to provide a sufficiently nuanced model of which cases count as relevantly similar. Resolving this problem requires deliberative capacities uniquely (...) available to human agents. After exploring the limitations of existing formal algorithmic fairness strategies, the article argues that procedural justice requires that human agents relying wholly or in part on algorithmic systems proceed with caution: by avoiding doxastic negligence about algorithmic outputs, by exercising deliberative capacities when making similarity judgments, and by suspending belief and gathering additional information in light of higher-order uncertainty.

I argue for a new conception of practical authority based on an analysis of the relationship between authority and subject. Commands entail a demand for practical deference, which establishes a relationship of hierarchy and vulnerability that involves a variety of signals and commitments. In order for these signals and commitments to be justified, the subject must be under a preexisting duty, the authority’s commands must take precedence over the subject’s judgment regarding fulfillment of that duty, the authority must accept the (...) position and responsibilities of command, and the authority must be sufficiently trustworthy relative to how vulnerable the subject makes herself by deferring. This results in an instrumentalist conception of practical authority that can be favorably compared to Joseph Raz’s famous service conception. The relational conception’s main advantage is that it focuses on the authority as much as the subject, requiring that the authority accept responsibility for the relationship and be sufficiently trustworthy.

Although written for a general philosophical audience, we attempt to provide a new perspective and highlight some underappreciated problems (...) about normative concepts. (shrink)

Michael Quante’s book Person offers a systematic and argumentative assessment of the question what a person is and accounts for the multiple aspects that play a role in our everyday understanding of the term.

At the same time he acknowledges that psychological considerations, including the notion of a person’s personality, are important (...) for practical purposes. However, one may wonder why he proposes the human organism as the remedy for the alleged shortcomings of the psychological approach, rather than introducing an additional physical continuity requirement of the cerebrum or other parts of the brain.

I develop a cognitive account of how humans make skeptical judgments (of the form “X does not know p”). In my view, these judgments are produced by a special purpose metacognitive "skeptical" mechanism which monitors our reasoning for hasty or overly risky assumptions. I argue that this mechanism is modular and shaped by natural selection. The explanation for why the mechanism is adaptive essentially relies on an internalized principle connecting knowledge and action, a principle central to pragmatic encroachment theories. I (...) end the paper by sketching how we can use the account I develop here to respond to the skeptic. (shrink)

Abstract Most discussions of risk are developed in broadly consequentialist terms, focusing on the outcomes of risks as such. This paper will provide an alternative account of risk from a virtue ethical perspective, shifting the focus to the decision to take the risk. Making ethical decisions about risk is, we will argue, not fundamentally about the actual chain of events that the decision sets in process, but about the reasonableness of the decision to take the risk in the first place. (...) A virtue ethical account of risk is needed because the notion of the ‘reasonableness’ of the decision to take the risk is affected by the complexity of the moral status of particular instances of risk-taking and the risk-taker’s responsiveness to these contextual features. The very idea of ‘reasonable risk’ welcomes judgments about the nature of the risk itself, raises questions about complicity, culpability and responsibility, while at its heart, involves a judgement about the justification of risk which unavoidably focuses our attention on the character of the individuals involved in risk making decisions. Keywords: Risk; ethics; morality; responsibility; virtue; choice; reasons . (shrink)

At a 2011 meeting of the Society of Christian Philosophers, N. T. Wright offered four reasons for rejecting the existence of soul. This was surprising, as many Christian philosophers had previously taken Wright's defense of a disembodied intermediate state as a defense of a substance dualist view of the soul. In this paper, I offer responses to each of Wright's objections, demonstrating that Wright's arguments fail to undermine substance dualism. In so doing, I expose how popular arguments against dualism fail, (...) such as dualism is merely an unwarranted influence of Greek culture on Christianity, and substance dualism is merely a soul-of-the-gaps hypothesis. Moreover, I demonstrate that Wright himself has offered a powerful reason for adopting substance dualism in his previous works. In conclusion I offer a view that explains why the human soul needs a resurrected body. (shrink)

When scientists seek further confirmation of their results, they often attempt to duplicate the results using diverse means. To the extent that they are successful in doing so, their results are said to be robust. This paper investigates the logic of such "robustness analysis" [RA]. The most important and challenging question an account of RA can answer is what sense of evidential diversity is involved in RAs. I argue that prevailing formal explications of such diversity are unsatisfactory. I propose a (...) unified, explanatory account of diversity in RAs. The resulting account is, I argue, truer to actual cases of RA in science; moreover, this account affords us a helpful, new foothold on the logic undergirding RAs. (shrink)

There are at least twelve major virtues of good theories: evidential accuracy, causal adequacy, explanatory depth, internal consistency, internal coherence, universal coherence, beauty, simplicity, unification, durability, fruitfulness, and applicability. These virtues are best classified into four classes: evidential, coherential, aesthetic, and diachronic. Each virtue class contains at least three virtues that sequentially follow a repeating pattern of progressive disclosure and expansion. Systematizing the theoretical virtues in this manner clarifies each virtue and suggests how they might have a coordinated and cumulative (...) role in theory formation and evaluation across the disciplines—with allowance for discipline specific modification. An informal and flexible logic of theory choice is in the making here. Evidential accuracy, according to my systematization, is not a largely isolated trait of good theories, as some have made it out to be. Rather, it bears multifaceted relationships, constituting significant epistemic entanglements, with other theoretical virtues. (shrink)

Sometimes two expressions in a discourse can be about the same thing in a way that makes that very fact evident to the participants. Consider, for example, 'he' and 'John' in 'John went to the store and he bought some milk'. Let us call this 'de jure' coreference. Other times, coreference is 'de facto' as with 'Mark Twain' and 'Samuel Clemens' in a sincere use of 'Mark Twain is not Samuel Clemens'. Here, agents can understand the speech without knowing that (...) the names refer to the same person. After surveying many available linguistic and pragmatic tools (intentions to corefer, presuppositions, meanings, indexing, discourse referents, binding etc.) I conclude that we must posit a new semantic primitive to account for de jure coreference.

Suppose that we repair a wooden ship by replacing its planks one by one with new ones while at the same time reconstructing it using the discarded planks. Some defenders of vague or indeterminate identity claim that: (1) although the reconstructed ship is distinct from the repaired ship, it is indeterminate whether the original ship is the reconstructed ship and indeterminate whether it is the repaired ship, and (2) the indeterminacy is due to the world and not just an imprecision (...) in the language used to describe the situation. I argue that such a description is incoherent. The argument has two features. First, it differs in spirit from Gareth Evans's more general famous proof against the possibility of indeterminate identity. This is because I rely on facts regarding counting and sets. Second, I focus on Terence Parsons's recent defence of indeterminate identity. I argue that his attempts at making sense of counting objects involving indeterminate identities fail on technical and philosophical grounds. (shrink)

Propensities are presented as a generalization of classical determinism. They describe a physical reality intermediary between Laplacian determinism and pure randomness, such as in quantum mechanics. They are characterized by the fact that their values are determined by the collection of all actual properties. It is argued that they do not satisfy Kolmogorov axioms; other axioms are proposed.

In these days, there is an increasing technological development in intelligent tutoring systems. This field has become interesting to many researchers. In this paper, we present an intelligent tutoring system for teaching mathematics that help students understand the basics of math and that helps a lot of students of all ages to understand the topic because it's important for students of adding and subtracting. Through which the student will be able to study the course and solve related problems. An evaluation (...) of the intelligent tutoring systems was carried out and the results were encouraging.

We present Backward Clock, an original counterexample to Robert Nozick’s truth-tracking analysis of propositional knowledge, which works differently from other putative counterexamples and avoids objections to which they are vulnerable.

Contrary to political and philosophical consensus, we argue that the threats posed by climate change justify population engineering, the intentional manipulation of the size and structure of human populations. Specifically, we defend three types of policies aimed at reducing fertility rates: choice enhancement, preference adjustment, and incentivization. While few object to the first type of policy, the latter two are generally rejected because of their potential for coercion or morally objectionable manipulation. We argue that forms of each policy type are (...) pragmatically and morally justified tools for preventing the harms of global climate change. (shrink)

In June 2002, Arthur Andersen LLP became the first accounting firm in history to be criminally convicted. The repercussions were immense. From a position as one of the leading professional services firms in the world, with 85,000 staff in 84 countries and revenues in excess of $9 billion, Andersen effectively ceased to exist within a matter of months. Although Andersen’s conviction related specifically to a charge of obstructing justice, public attention focused on the audit relationship between Andersen and its major (...) client, Enron Corporation, particularly the actions that had allowed Enron to post spectacular year-on-year earnings and profit growth. As well as examining events leading up to the demise of Andersen, the case provides an opportunity to consider the broader controversy over accounting and corporate governance practices and, more generally, the pressures found within organisations that can foster unethical conduct. The case was prepared from public sources. (shrink)

In robustness analysis, hypotheses are supported to the extent that a result proves robust, and a result is robust to the extent that we detect it in diverse ways. But what precise sense of diversity is at work here? In this paper, I show that the formal explications of evidential diversity most often appealed to in work on robustness – which all draw in one way or another on probabilistic independence – fail to shed light on the notion of diversity (...) relevant to robustness analysis. I close by briefly outlining a promising alternative approach inspired by Horwich’s (1982) eliminative account of evidential diversity. (shrink)
