To describe phenomena that occur at different time scales, computational models of the brain must incorporate different levels of abstraction. At time scales of approximately 1/3 of a second, orienting movements of the body play a crucial role in cognition and form a useful computational level embodiment level,” the constraints of the physical system determine the nature of cognitive operations. The key synergy is that at time scales of about 1/3 of a second, the natural sequentiality of body movements can (...) be matched to the natural computational economies of sequential decision systems through a system of implicit reference called deictic in which pointing movements are used to bind objects in the world to cognitive programs. This target article focuses on how deictic bindings make it possible to perform natural tasks. Deictic computation provides a mechanism for representing the essential features that link external sensory data with internal cognitive programs and motor actions. One of the central features of cognition, working memory, can be related to moment-by-moment dispositions of body features such as eye movements and hand movements. (shrink)

Animate vision systems have gaze control mechanisms that can actively position the camera coordinate system in response to physical stimuli. Compared to passive systems, animate systems show that visual computation can be vastly less expensive when considered in the larger context of behavior. The most important visual behavior is the ability to control the direction of gaze. This allows the use of very low resolution imaging that has a high virtual resolution. Using such a system in a controlled way provides (...) additional constraints that dramatically simplify the computations of early vision. Another important behavior is the way the environment “behaves‘. Animate systems under real-time constraints can further reduce their computational burden by using environmental cues that are perspicuous in the local context. A third source of economy is introduced when behaviors are learned. Because errors are rarely fatal, systems using learning algorithms can amortize computational cost over extended periods. Further economies can be achieved when the learning system uses indexical reference, which is a form of dynamic variable binding. Animate vision is a natural way of implementing this dynamic binding.

The cerebral cortex is a rich and diverse structure that is the basis of intelligent behavior. One of the deepest mysteries of the function of cortex is that neural processing times are only about one hundred times as fast as the fastest response times for complex behavior. At the very least, this would seem to indicate that the cortex does massive amounts of parallel computation.This paper explores the hypothesis that an important part of the cortex can be modeled as a (...) connectionist computer that is especially suited for parallel problem solving. The connectionist computer uses a special representation, termed value unit encoding, that represents small subsets of parameters in a way that allows parallel access to many different parameter values. This computer can be thought of as computing hierarchies of sensorimotor invariants. The neural substrate can be interpreted as a commitment to data structures and algorithms that compute invariants fast enough to explain the behavioral response times. A detailed consideration of this model has several implications for the underlying anatomy and physiology. (shrink)

Ballard and Zhang offer a fascinating review of how computational models of human vision have evolved since David Marr proposed his Tri‐Level Hypothesis, with a focus on the refinement of algorithm descriptions over time.

Our seamless perception of the world depends very much on the slow time scales used by conscious perception. Time scales longer than one second are needed to assemble conscious experience. At time scales shorter than one second, this seamlessness quickly deteriorates. Numerous experiments reveal the fragmentary nature of the visual information used to construct visual experience. Models of how the brain manages these fragments use the construct of a routine, which is a task-specific fragment of a sensory-motor program. This paper (...) provides an overview of some of the experiments that test these models. Its aim is to show how the structures that they elucidate constrain the understanding of conscious perception.

Our computational studies of infant language learning estimate the inherent difficulty of Arbib's proposal. We show that body language provides a strikingly helpful scaffold for learning language that may be necessary but not sufficient, given the absence of sophisticated language in other species. The extraordinary language abilities of Homo sapiens must have evolved from other pressures, such as sexual selection.

The majority of commentators agree that the time to focus on embodiment has arrived and that the disembodied approach that was taken from the birth of artificial intelligence is unlikely to provide a satisfactory account of the special features of human intelligence. In our Response, we begin by addressing the general comments and criticisms directed at the emerging enterprise of deictic and embodied cognition. In subsequent sections we examine the topics that constitute the core of the commentaries: embodiment mechanisms, dorsal (...) and ventral visual processing, eye movements, and learning. (shrink)

Freight transportation plays a critical role in improving company performance in the modern manufacturing industry. To reduce costs, companies must take advantage of the use of large vehicles. It caused fewer deliveries, but inventory costs and degradation quality are high. One of the joint economic lot size problems in supply chain is Integrated Single-Vendor Single-Buyer Inventory Problem. This study developed the I-SVSB-IP model that considers raw materials’ exponential quality degradation and transportation costs. The objective function of this research was to (...) maximize the Joint Total Profit. Three decision variables used were inventory cycle time, raw material ordering frequency, and frequency of delivery of finished products to buyers. This study proposed a sophisticated Chimp Optimization Algorithm procedure to solve the I-SVSB-IP problem. A case study on the food industry in Indonesia was presented to optimize the I-SVSB-IP. The results showed that the ChOA procedure had produced an optimal solution compared to the state-of-the-art algorithm. This study also demonstrated a sensitivity analysis of decision and transportation variables to cost, revenue, and JTP. The results show that increasing transport frequency of ordering raw materials and finished products to buyers enhances the total cost and reduces joint total profit. In addition, increasing the rate of quality degradation of raw materials reduces JTP. (shrink)

Much of the progress in the fields constituting cognitive science has been based upon the use of explicit information processing models, almost exclusively patterned after conventional serial computers. An extension of these ideas to massively parallel, connectionist models appears to offer a number of advantages. After a preliminary discussion, this paper introduces a general connectionist model and considers how it might be used in cognitive science. Among the issues addressed are: stability and noise‐sensitivity, distributed decision‐making, time and sequence problems, and (...) the representation of complex concepts. (shrink)

Much attention has been focused in recent years on the ethical acceptability of physicians receiving gifts from drug companies. Professional guidelines recognize industry gifts as a conflict of interest and establish thresholds prohibiting the exchange of large gifts while expressly allowing for the exchange of small gifts such as pens, note pads, and coffee. Considerable evidence from the social sciences suggests that gifts of negligible value can influence the behavior of the recipient in ways the recipient does not always realize. (...) Policies and guidelines that rely on arbitrary value limits for gift-giving or receipt should be reevaluated. (shrink)

Nelkin presents a simple and natural account of freedom and moral responsibility which responds to the great variety of challenges to the idea that we are free and responsible, before ultimately reaffirming our conception of ourselves as agents. Making Sense of Freedom and Responsibility begins with a defense of the rational abilities view, according to which one is responsible for an action if and only if one acts with the ability to recognize and act for good reasons. The view is (...) compatibilist -- that is, on the view defended, responsibility is compatible with determinism -- and one of its striking features is a certain asymmetry: it requires the ability to do otherwise for responsibility when actions are praiseworthy, but not when they are blameworthy. In defending and elaborating the view, Nelkin questions long-held assumptions such as those concerning the relation between fairness and blame and the nature of so-called reactive attitudes such as resentment and forgiveness. Her argument not only fits with a metaphysical picture of causation -- agent-causation -- often assumed to be available only to incompatibilist accounts, but receives positive support from the intuitively appealing Ought Implies Can Principle, and establishes a new interpretation of freedom and moral responsibility that dovetails with a compelling account of our inescapable commitments as rational agents.

This Very Short Introduction explores the philosophical ideas and political theories of Hannah Arendt (1906-1975). As a survivor of the Holocaust, Arendt's life informed her work exploring the meaning and construction of power, evil, totalitarianism, and direct democracy. Through insightful readings of Arendt's best-known works, from The Origins of Totalitarianism (1951) to The Life of the Mind (1978), Dana Villa traces the importance of Arendt's ideas for today's reader. In so doing, Villa explains how Arendt gained world-wide fame with (...) the publication of Origins, and went on to have a distinguished career as a political theorist and public intellectual. A sometimes controversial figure, Arendt is now recognised as one of the most important political thinkers of the twentieth century and her works have become an acknowledged part of the Western canon of political theory and philosophy"--From the publisher.

Paul Ricoeur was one of the foremost interpreters and translators of Edmund Husserl's philosophy. These nine essays present Ricoeur's interpretation of the most important of Husserl's writings, with emphasis on his philosophy of consciousness rather than his work in logic. In Ricoeur's philosophy, phenomenology and existentialism came of age and these essays provide an introduction to the Husserlian elements which most heavily influenced his own philosophical position.

In response to the charge that deontic ("argent-centered") restrictions are paradoxical, several recent writers suggest that such restrictions find support within T.M. Scanlon's contractualism. I suggest that this claim is only interesting if these restrictions are stronger than those supported by indirect consequentialism. I argue that contractualism cannot support restrictions any stronger than those supported by indirect consequentialism. The contractualists have mislocated the source of the paradox, which arises under any theory that defines right action in patient-focused terms. Consequentialism and (...) contractualism share this feature, so contractualism cannot support stronger deontic restrictions than consequentialism supports. (shrink)

With the continual development of artificial intelligence and smart computing in recent years, quantitative approaches have become increasingly popular as an efficient modeling tool as they do not necessitate complicated mathematical models. Many nations have taken steps, such as transitioning to online schooling, to decrease the harm caused by coronaviruses. Inspired by the demand for technology in early education, the present research uses a radial basis function neural network modeling technique to predict preschool instructors’ technology usage in classes based on (...) recognized determinant characteristics of technology acceptance. In this regard, this study utilized the RBFNN approach to predict preschool teachers’ technology acceptance behavior, based on the theory of planned behavior, which states that behavioral achievement, in our case the actual technology use in class, depends on motivation, intention and ability, and behavioral control. Thus, this research design is based on an adapted version of the technology acceptance model with eight dimensions: D1. Perceived usefulness, D2. Perceived ease of use, D3. Perceived enjoyment, D4. Intention to use, D5. Actual use, D6. Compatibility, D7. Attitude, and D8. Self-efficacy. According to the TAM, actual usage is significantly predicted by the other seven dimensions used in this research. Instead of using the classical multiple linear regression statistical processing of data, we opted for a NN based on the RBF approach to predict the actual usage behavior. This study included 182 preschool teachers who were randomly chosen from a project-based national preschool teacher training program and who responded to our online questionnaire. After designing the RBF function with the actual usage as an output variable and the other seven dimensions as input variables, in the model summary, we obtained in the training sample a sum of squares error of 37.5 and a percent of incorrect predictions of 43.3%. In the testing sample, we obtained a sum of squares error of 14.88 and a percent of incorrect predictions of 37%. Thus, we can conclude that 63% of the classified data are correctly assigned to the models’ dependent variable, i.e., actual technology use, which is a significant rate of correct predictions in the testing sample. This high significant percentage of correct classification represents an important result, mainly because this is the first study to apply RBFNN’s prediction on psychological data, opening up a new interdisciplinary field of research.

: Biomedical ethicists often assume that common morality constitutes a largely consistent normative system. This premise is not taken for granted in general normative ethics. This paper entertains the possibility of inconsistency within common morality and explores methodological implications. Assuming common morality to be inconsistent casts new light on the debate between principlists and descriptivists. One can view the two approaches as complementary attempts to evade or transcend that inconsistency. If common morality proves to be inconsistent, then principlists might have (...) reason to prefer a less pluralistic theory, thereby moving closer to descriptivism. Descriptivists, by contrast, might want to qualify their claim to accommodate all of people's basic moral convictions. Finally, both camps might wish to adopt a more revisionist posture, accepting that an adequate ethical theory occasionally will contradict some of people's deepest moral convictions. Proper application of the method of reflective equilibrium, to which both descriptivists and principlists claim allegiance, may entail greater openness to revisionism than either camp admits.

Retributive restrictions are principles of justice according to which what a criminal deserves on account of his individual conduct and character restricts how states are morally permitted to treat him. The main arguments offered in defense of retributive restrictions involve thought experiments in which the state punishes the innocent, a practice known as telishment. In order to derive retributive restrictions from the wrongness of telishment, one must engage in moral argument from generalization. I show how generalization arguments of the same (...) form can be used subversively to derive morally unacceptable conclusions from other scenarios in which the state intentionally inflicts undeserved coercion. For example, our considered moral convictions approve of punishment policies that inflict collateral damage, such as the ubiquitous policy of excluding the family members of inmates from prison facilities outside visiting hours. I present a generalization argument for the conclusion that these policies are seriously unjust. If we firmly believe that these policies are not unjust, then we should put less stock in generalization arguments. We should not use them to support retributive restrictions. This conclusion has broad implications for the theory and practice of criminal justice. (shrink)

Many philosophers hold that it is conceptually impossible to form a belief simply by willing it. Noting the failure of previous attempts to locate the presumed incoherence, Dion Scott-Kakures offers a version of the general line that voluntary believing is conceptually impossible because it could not qualify as a basic intentional action. This discussion analyzes his central argument, explaining how it turns on the assumption that a prospective voluntary believer must regard the desired belief as not justified, given her other (...) beliefs. It then shows that this assumption is false and also that some initially plausible suggestions for weakening the assumption fail to secure Scott-Kakures’s conclusion. (shrink)

Considerable attention has been paid recently to the gendering of organizations and occupations. Unfortunately, the gendered-organizations approach remains theoretically and empirically underdeveloped, as there have as yet been few clear answers to the question central to the perspective: What does it really mean to say that an organization itself, or a policy, practice, or slot in the hierarchy, is “gendered”? Reviewing literature in the gendered-organizations tradition, the author discusses three of the most common ways the perspective has been applied and (...) argues that all of these definitions pose potential problems for the project of meaningful social and organizational change. The article concludes with some suggestions about how a more useful conception of the gendered organization might be built. (shrink)

In The Minority Body, Elizabeth Barnes rejects prevailing social constructionist accounts of disability for two reasons. First, because they understand disability in terms of oppressive social responses to bodily impairment, they cannot make sense of disability pride. Second, they maintain a problematic distinction between impairment and disability. In response to these challenges, this paper defends a version of the social model of disability, which we call the Social Exclusion Model. On our account, to be disabled is to be in a (...) bodily or psychological state that is represented as an impairment in the prevailing ideology of one’s society, and to be excluded from valuable activities on the basis of this representation. While this model refers to a distinction between disability and impairment, it makes no presuppositions about which bodies function ‘normally’ and which do not. It is the ideology of impairment rather than impairment itself that does any work to determine whether a person is disabled. We argue that this model answers some of the important objections that Barnes raises against prevailing social constructionist accounts of disability, and that it’s focus on the oppressive social positioning of disabled people gives it explanatory power that Barnes’s own account lacks.

In everyday life, we assume that there are degrees of blameworthiness and praiseworthiness. Yet the debate about the nature of moral responsibility often focuses on the “yes or no” question of whether indeterminism is required for moral responsibility, while questions about what accounts for more or less blameworthiness or praiseworthiness are underexplored. In this paper, I defend the idea that degrees of blameworthiness and praiseworthiness can depend in part on degrees of difficulty and degrees of sacrifice required for performing the (...) action in question. Then I turn to the question of how existing accounts of the nature of moral responsibility might be seen to accommodate these facts. In each case of prominent compatibilist and incompatibilist accounts that I consider, I argue that supplementation with added dimensions is required in order to account for facts about degrees of blameworthiness and praiseworthiness. For example, I argue that the reasons-responsiveness view of Fischer and Ravizza requires supplementation that takes us beyond even fine-grained measures of degrees of reasons-responsiveness in order to capture facts about degrees of difficulty to extend the reasons-responsiveness view by appealing to such measures). I conclude by showing that once we recognize the need for these additional parameters, we will be in a position to explain away at least some of the appeal of incompatibilist accounts of moral responsibility.

Theodor Adorno once wrote an essay to "defend Bach against his devotees." In this book Dana Villa does the same for Hannah Arendt, whose sweeping reconceptualization of the nature and value of political action, he argues, has been covered over and domesticated by admirers who had hoped to enlist her in their less radical philosophical or political projects. Against the prevailing "Aristotelian" interpretation of her work, Villa explores Arendt's modernity, and indeed her postmodernity, through the Heideggerian and Nietzschean theme (...) of a break with tradition at the closure of metaphysics.Villa's book, however, is much more than a mere correction of misinterpretations of a major thinker's work. Rather, he makes a persuasive case for Arendt as the postmodern or postmetaphysical political theorist, the first political theorist to think through the nature of political action after Nietzsche's exposition of the death of God. After giving an account of Arendt's theory of action and Heidegger's influence on it, Villa shows how Arendt did justice to the Heideggerian and Nietzschean criticism of the metaphysical tradition while avoiding the political conclusions they drew from their critiques. The result is a wide-ranging discussion not only of Arendt and Heidegger, but of Aristotle, Kant, Nietzsche, Habermas, and the entire question of politics after metaphysics. (shrink)

We examined the links between moral identity—the centrality of moral principles to identity—and political purpose during emerging adulthood. We analyzed data from two waves of a longitudinal study of civic purpose. T1 surveys were collected before high school graduation and T2 survey were collected two years later. We categorized people (N = 1,578 at T1 and N = 480 at T2) into political purpose groups based on the person-centered perspective and then performed multinomial logistic regression analysis to test whether moral (...) identity was associated with categories of political purpose. The findings from our study indicate that moral identity at T1 is linked with the maintenance and formation of T2 political purpose. (shrink)

It is argued that once biological systems reach a certain level of complexity, mechanistic explanations provide an inadequate account of many relevant phenomena. In this article, I evaluate such claims with respect to a representative programme in systems biological research: the study of regulatory networks within single-celled organisms. I argue that these networks are amenable to mechanistic philosophy without need to appeal to some alternate form of explanation. In particular, I claim that we can understand the mathematical modelling techniques of (...) systems biologists as part of a broader practice of constructing and evaluating mechanism schemas. This argument is elaborated by considering the case of bacterial chemotactic networks, where some research has been interpreted as explaining phenomena by means of abstract design principles.

The doctrine of double effect, together with other moral principles that appeal to the intentions of moral agents, has come under attack from many directions in recent years, as have a variety of rationales that have been given in favor of it. In this paper, our aim is to develop, defend, and provide a new theoretical rationale for a secular version of the doctrine. Following Quinn (1989), we distinguish between Harmful Direct Agency and Harmful Indirect Agency. We propose the following (...) version of the doctrine: that in cases in which harm must come to some in order to achieve a good (and is the least costly of possible harms necessary), the agent foresees the harm, and all other things are equal, a stronger case is needed to justify Harmful Direct Agency than to justify Harmful Indirect Agency. We distinguish between two Kantian rationales that might be given for the doctrine, a “dependent right” rationale, defended by Quinn, and an “independent right” rationale, which we defend. We argue that the doctrine and the “independent right” rationale for it are not vulnerable to counterexamples or counterproposals, and conclude by drawing implications for the larger debate over whether agents' intentions are in any way relevant to permissibility and obligation.
