The ipsilesional arm of stroke patients often has functionally limiting deficits in motor control and dexterity that depend on the side of the brain that is lesioned and that increase with the severity of paretic arm impairment. However, remediation of the ipsilesional arm has yet to be integrated into the usual standard of care for upper limb rehabilitation in stroke, largely due to a lack of translational research examining the effects of ipsilesional-arm intervention. We now ask whether ipsilesional-arm training, tailored (...) to the hemisphere-specific nature of ipsilesional-arm motor deficits in participants with moderate to severe contralesional paresis, improves ipsilesional arm performance and generalizes to improve functional independence. We assessed the effects of this intervention on ipsilesional arm unilateral performance [Jebsen–Taylor Hand Function Test ], ipsilesional grip strength, contralesional arm impairment level [Fugl–Meyer Assessment ], and functional independence [Functional independence measure ]. Intervention occurred over a 3 week period for 1.5 h/session, three times each week. All sessions included virtual reality tasks that targeted the specific motor control deficits associated with either left or right hemisphere damage, followed by graded dexterity training in real-world tasks. We also exposed participants to 3 weeks of sham training to control for the non-specific effects of therapy visits and interactions. We conducted five test-sessions: two pre-tests and three post-tests. Our results indicate substantial improvements in the less-impaired arm performance, without detriment to the paretic arm that transferred to improved functional independence in all three posttests, indicating durability of training effects for at least 3 weeks. We provide evidence for establishing the basis of a rehabilitation approach that includes evaluation and remediation of the ipsilesional arm in moderately to severely impaired stroke survivors. This study was originally a crossover design; however, we were unable to complete the second arm of the study due to the COVID-19 pandemic. We report the results from the first arm of the planned design as a longitudinal study. (shrink)

This paper is an empirical inquiry into the nature of human communication and understanding. It is organized into three sections. First, there is an overview of the ethnomethodological critique of mainstream social scientific research methodology and the relevance of this critique to clinical behavioral research. Second, the details of an ethnomethodological study of communication practices in a family with an alingual, deaf-blind child are provided. Third, implications of the case study are presented.

In this comprehensive collection of essays, most of which appear for the first time, eminent scholars from many disciplines—philosophy, economics, sociology, political science, demography, theology, history, and social psychology—examine the causes, nature, and consequences of present-day consumption patterns in the United States and throughout the world.

In The Law of Peoples, John Rawls does not discuss justice and the global economy at great length or in great detail. What he does say has not been well-received. The prevailing view seems to be that what Rawls says in The Law of Peoples regarding global economic justice is both inconsistent with and a betrayal of his own liberal egalitarian commitments, an unexpected and unacceptable defense of the status quo. This view is, I think, mistaken. Rawls’s position on global (...) or international economic justice is richer, more nuanced, and generally more compelling than his critics have been willing to acknowledge. My aim in this essay is to sympathetically set out, and then defend against two common families of objection to, Rawls’s position on global or international economic justice. Objections of the first sort reject Rawls’s position as inadequately attentive to the material and economic interests of individual persons worldwide. Objections of the second sort reject it as inadequately attentive to the material and economic interests of well-ordered peoples. Throughout the paper I develop several arguments implicit in The Law of Peoples but not well-developed there as well as offer some additional arguments of my own consistent with the spirit of The Law of Peoples and Rawls’s work more generally. I conclude with some brief remarks expressing two worries I have about Rawls’s position – one concerning global public goods, the other concerning the formation of a morally adequate and effective political will within the international context under contemporary conditions.

Asserting that previous attempts to characterize the essence of the cosmos have fallen short for their lack of an adequate conceptual arsenal, as exemplified by Maimonides' and Aristotle's impasse, he consolidates these eclectic influences into a defined set of metaphysical "tools." Birnbaum presents these tools at the outset of God and Good. He then uses them to build a model that is applicable to all the arenas from which its influences were initially derived.

This article begins by clarifying and noting various limitations on the universal reach of the human right to health care under positive international law. It then argues that irrespective of the human right to health care established by positive international law, any system of positive international law capable of generating legal duties with prima facie moral force necessarily presupposes a universal moral human right to health care. But the language used in contemporary human rights documents or human rights advocacy is (...) not a good guide to the content of this rather more modest universal moral human right to health care. The conclusion reached is that when addressing issues of justice as they inevitably arise with respect to health policy and health care, both within and between states, there is typically little to gain and much to risk by framing deliberation in terms of the human right to health care.

Media appeals encouraging people to sign organ donor cards suggest that donating one's own organs after death or donating the organs of a deceased family member is an act of charity, i.e., something which it would be meritorious for people to do but not wrong to avoid. This paper argues to the contrary that posthumous organ donation is a moral duty, a duty of the type that rests at the base of recently enacted state “Good Samaritan” laws which require a (...) witness to an emergency situation to render aid to the victim when this can be done at minimal cost/risk to the potential rescuer.

Money does not stimulate receptors in mimicry of natural agonists; so, by definition, money is not a drug. Attractions of money other than to purchase goods and services could arise from instincts similar to hoarding in other species. Instinctual activities without evolutionary function include earning a billion and writing for BBS. (Published Online April 5 2006).

Chronic stroke survivors with severe contralesional arm paresis face numerous challenges to performing activities of daily living, which largely rely on the use of the less-affected ipsilesional arm. While use of the ipsilesional arm is often encouraged as a compensatory strategy in rehabilitation, substantial evidence indicates that motor control deficits in this arm can be functionally limiting, suggesting a role for remediation of this arm. Previous research has indicated that the nature of ipsilesional motor control deficits vary with hemisphere of (...) damage and with the severity of contralesional paresis. Thus, in order to design rehabilitation that accounts for these deficits in promoting function, it is critical to understand the relative contributions of both ipsilesional and contralesional arm motor deficits to functional independence in stroke survivors with severe contralesional paresis. We now examine motor deficits in each arm of severely paretic chronic stroke survivors with unilateral damage to determine whether hemisphere-dependent deficits are correlated with functional independence. Clinical evaluation of contralesional, paretic arm impairment was conducted with the upper extremity portion of the Fugl-Meyer assessment. Ipsilesional arm motor performance was evaluated using the Jebsen-Taylor Hand Function Test, grip strength, and ipsilesional high-resolution kinematic analysis during a visually targeted reaching task. Functional independence was measured with the Barthel Index. Functional independence was better correlated with ipsilesional than contralesional arm motor performance in the left hemisphere damage group [JTHFT: [r = −0.73, p = 0.017]; grip strength: [r = 0.64, p = 0.047]], and by contralesional arm impairment in the right hemisphere damage group [UEFM: [r = 0.66, p = 0.040]]. Ipsilesional arm kinematics were correlated with functional independence in the left hemisphere damage group only. Examination of hemisphere-dependent motor correlates of functional independence showed that ipsilesional arm deficits were important in determining functional outcomes in individuals with left hemisphere damage only, suggesting that functional independence in right hemisphere damaged participants was affected by other factors.

On Peirce’s terms, the history of philosophy is a vast field of mind, a complexifying network of general ideas that contribute to the formation and valorization of human civilization through the expressions of individual authors and schools in their culturally specific times. The accumulating legacy of philosophical wisdom underwrites these individual expressions. But while for short term good reasons contemporary scholarship trends towards the exegesis of individual authors and schools, the “professional” practice runs the danger of being narrow-gauge in scholarly (...) focus. The excitement of Peirce, and for that matter any major author, consists in adjudicating his place in the “cosmical” or public space of.. (shrink)

Bisphosphonates are a class of drugs which have shown good efficacy in the treatment of post‐menopausal osteoporosis, as well as a good safety profile. However, side‐effects such as risk for atypical femoral fractures (AFF) have appeared, leading to a decline in use of the drugs by many patients who would benefit from the treatment. While patient characteristics have contributed to improved understanding of risk factors, the mechanisms involved that explain AFF risk have not appeared. Recently, the possibility that the mechanism(s) (...) involved drug‐induced modification of cells of the nutrient canals of the femur and subsequent compromise in the bone matrix has been published. The present Hypothesis article builds on the concept presented earlier and expands into biomechanical considerations. An analogy of the mechanisms involved to a real‐life scenario is also presented. While this analogy has limitations, consideration of the biomechanical implications of progressive alterations to defects presented by compromised nutrient canal‐bone matrix also presents potential relationships with AFF risk.

This essay examines the relationship between virtue and understandings of time through a comparative examination of two medieval Christian writers, Bernard of Clairvaux and Thomas Aquinas. By locating temporal dimensions of virtue primarily in discussions of prudence, this essay compares Thomas's account of the virtue of counsel as preparatory to prudent judgment with Bernard's earlier account of consideration as an integrating virtue that coordinates an examination of physical surroundings and social responsibilities with an examination of one's own inner life and (...) history of moral decisions. The essay argues that accounts of virtue ethics focusing on tradition-specific views of the human good and practical reasoning are insufficient if they do not also examine how practical reasoning interprets and responds to religious interpretations of time that disclose the distinctive kinds of moral problems arising in each historical period.

Barbey & Sloman attribute all instances of normative base-rate usage to a rule-based system, and all instances of neglect to an associative system. As it stands, this argument is too simplistic, and indeed fails to explain either good or bad performance on the classic Medical Diagnosis problem.

In this book, Professor David Starrett organizes within a single framework the major theoretical foundations of modern public sector economics. He presents a unified treatment of market failure that encompasses externalities, pure public goods, local public goods and natural monopolies. Professor Starrett then develops and assesses the efficacy of the various planning procedures - including representative voting, benefit cost analysis, incentive compatible design mechanisms and the free market. He devotes attention to both national and local issues, with the aim (...) of identifying those methods that are best suited to each arena separately. Special attention is paid to financial arrangements, techniques for eliciting necessary information that is not readily available, and identification of biases that will result from incorrect procedures. This study will be useful to graduate students and economists who are interested in public finance or welfare economics. (shrink)

This paper suggests that young people can explore moral philosophy in ways that will help them both think and act in ways that are consistent with good moral reasoning. It describes several games and exercises that allow children to explore various moral principles in their behavior toward others. Participating in activities that give children practice in making moral decisions helps them to appreciate the role of principles in moral reasoning. The author contends that it is important for young people to (...) examine ethical dilemmas from the “inside out”; that is, not by listening to the wisdom of philosophers telling them how to approach these issues, but by facing them head on themselves.

Folly is an under-explored vice, despite its common occurrence and close relationship to core aspects of practical rationality and the good life. This paper develops an account of folly as a subspecies of imprudence and distinctive source of wrongdoing, with a special focus on its relational, social or inter-personal aspect. Drawing on Rotenstreich’s historically-based account, folly is defined as a form of practical irrationality resulting from closedness to the world. I expand Rotenstreich’s view and depart from him on two key (...) points. First, I argue that folly should be cleanly differentiated from stupidity. Second, I show that the wrong in folly—i.e. the harms it involves intrinsically, as opposed to as a matter of causal consequence—is partly obscured by Rotenstreich’s exclusive focus on the fool as an isolated individual agent. When, instead, we consider folly as a pathology of interpersonal relations, it reveals itself to be a vice which infects and undermines human relationships of love and care, and thus to be a serious threat to living well or human flourishing in almost all of their forms.

The recent case of Baby Theresa has once again raised the dilemma of organ donation from anencephalic infants. Baby Theresa's distraught parents wanted to create something good from something tragic, by donating the baby's organs so that other children could live. If the physician waited for their baby to die naturally, the organs would not be suitable for transplantation. If they took them before death they could be harvested. For this reason, the parents petitioned the Florida courts to declare their (...) baby dead at birth so the organs could be removed at an earlier, more propitious time. The court refused. The infant died, its vital organs unusable. (shrink)

The best arguments for possible worlds as states of affairs furnish us with equally good arguments for impossible worlds of the same sort. I argue for a theory of impossible worlds on which the impossible worlds correspond to maximal inconsistent classes of propositions. Three objections are rejected. In the final part of the paper, I present a menu of impossible worlds and explore some of their interesting formal properties.

Gangestad & Simpson's model of the evolution of within-sex differences in reproductive strategies requires a degree of female choice that probably did not exist because of male coercion. We argue as well that the tradeoff between current and future reproduction accounts for more of the within-sex differences in reproductive strategies than the “good-genes-good parenting” tradeoff they propose.

Page's target article makes a good case for the strength of localist models. This can be characterized as an issue of where new information is integrated with respect to existing knowledge structures. We extend the analysis by discussing the dimension of when this integration takes place, the implications, and how they guide us in the creation of cognitive models.

What if philosophy, theology, and science spent a little more time together? These fields often seem at odds, butting metaphysical heads. Instead of talking at, how about talking with one another? This book engages three academic disciplines--distinct yet sharing much in common--in a slice of conversation and community in which participants have aimed at validating the other and the way the other sees the world. The result is a collection of essays united by a thread that can be hard to (...) find in academia. In bringing together a wide range of contributors on a project that at first seemed unlikely, Irreconcilable Differences? is also a testament to the spirit of cooperation and hard work--evidence that small acts and events can make a big difference, and that sometimes all you need in order to make something good happen is an idea with a little support along the way. The editors of this collection are hopeful that its contributors and readers will keep looking for ways to bridge academic, social, and political gaps. We need to forge relationships based on personal knowledge and proper confidence seeking to make meaningful claims in an increasingly complex world. (shrink)

For many years, researchers and practitioners have sought out meaningful indicators of sales performance. Yet, as the concept of performance has broadened, the understanding of what makes up a successful seller, has become far more complicated. The complexity of buyer-seller relationships has changed therefore as the definition of sales performance has expanded, cultivating a growing interest in ethical/unethical actions since they could potentially have impacts on sales performance. Given this environment, the purpose of this study is to explore the impact (...) of moral judgment on sales performance and sellers engaging in a customer-oriented selling approach. Specifically, by utilizing a sample of 345 business-to-business salespeople, this study examines the relationships between moral judgment, customer-oriented selling, and outcome and behavior based performance. Results, managerial implications, and opportunities for future research are provided. (shrink)

I argue that thought experiments are a form of experimental reasoning similar to real experiments. They require the same ability to participate by following a narrative as real experiments do. Participation depends in turn on using what we already know to visualize, manipulate and understand what is unfamiliar or problematic. I defend the claim that visualization requires embodiment by an example which shows how tacit understanding of the properties of represented objects and relations enables us to work out how such (...) objects might behave in a postulated world. This knowledge is that of embodied agents. That thought experiments require embodied participation is what makes them experiments rather than arguments. Unlike real experiments, from which ordinary perception has been displaced by instrumentation, thought experiments still appeal to relatively unmediated common sense, even when their purpose is to criticize or subvert common sense notions.

I outline a pragmatic view of scientists' use of observation which draws attention to non-discursive, instrumental and social contexts of observation, in order to explain scientists' agreement about the appearance and significance of new phenomena. I argue that: observation is embedded in a network of activities, techniques, and interests; that experimentalists make construals of new phenomena which enable them communicate exploratory techniques and their outcomes, and that empirical enquiry consists of communicative, exploratory and predictive strategies whose interdependence ensures that, notwithstanding (...) the constructedness of representations and the empirical underdetermination of theories, observations contain information about the natural world.

Narrative accounts misrepresent discovery by reconstructing worlds ordered by success rather than the world as explored. Such worlds rarely contain the personal knowledge that informed actual exploration and experiment. This article describes an attempt to recover situated learning in a material environment, tracing the discovery of the first electromagnetic motor by Michael Faraday in September 1821 to show how he modeled new experience and invented procedures to communicate that novelty. The author introduces a notation to map experiment as an active (...) process in a real-world environment and to display the human agency written out of most narratives. Comparing maps of accounts shows how knowledge-construction depends on narrative reconstruction. It is argued that invention processes can be interpreted in the same way as discovery, and a study is proposed to compare packaging learned skills into demonstration devices with the innovative strategies of inventors such as Edison. If situational knowledge is as important as is claimed, computationalists need to join science studies scholars in coming to grips with nonverbal and procedural aspects of discovery and invention.

The sciences use a wide range of visual devices, practices, and imaging technologies. This diversity points to an important repertoire of visual methods that scientists use to adapt representations to meet the varied demands that their work places on cognitive processes. This paper identifies key features of the use of visualization in a range of scientific domains and considers the implications of this repertoire for understanding scientists as cognitive agents.

This paper considers the potentially important role played by non-verbal communication in constraining pragmatic processing. Attention is paid to claims about the role of emotion in memory encoding and recall, its role in the formulation of plans and goals, and the creation of a shared emotional sense through various interpersonal processes. It is argued that ignoring these factors can lead to pragmatic theories which overestimate the processing demands facing the conversationalist, and that this overestimation will be problematic for any systems (...) which seek to build on these theories in the future.

This paper presents a study of the generation, manipulation and use of visual representations in different episodes of scientific discovery. The study identifies a common set of transformations of visual representations underlying the distinctive methods and imagery of different scientific fields. The existence of common features behind the diversity of visual representations suggests a common dynamical structure for visual thinking, showing how visual representations facilitate cognitive processes such as pattern-matching and visual inference through the use of tools, technologies and other (...) cultural resources. This dynamical model suggests a way of theorizing the interaction of cognitive, socio-cultural and technological aspects of science without losing sight of the essential contribution each makes to the processes of discovery. Whereas scientific work is often construed epistemically, as having the aim of improving the fit between theories and phenomena or culturally given notions of what counts as reality, this study shows that scientists use transformations to modify visual representations in ways that achieve other kinds of match: between a representation and the cognitive demands of a task or between an emerging representation and the social need to communicate and negotiate new meanings in a context of culturally embedded conventions. By showing how images connect each of the overlapping contexts of scientific work the proposed model negotiates the sometimes contested boundary between cognitive and social aspects of science.

: Faraday is often described as an experimentalist, but his work is a dialectical interplay of concrete objects, visual images, abstract, theoretically-informed visual models and metaphysical precepts. From phenomena described in terms of patterns formed by lines of force he created a general explanation of space-filling systems of force which obey both empirical laws and principles of conservation and economy. I argue that Faraday's articulation of situated experience via visual models into a theory capable of verbal expression owed much to (...) his strategy of moving—via conjectural visual models—between the phenomenology of particulars (often displayed as patterns) and the general features of dynamical phenomena which he depicted as structures.

SummaryFaraday's concept of force is described by six assumptions. These specify a concept that is quite distinct from ‘mechanical’ conceptions of his contemporaries and interpreters. Analysis of the role of these assumptions clarifies Faraday's weighting of experimental evidence and shows how closely-linked Faraday's chemistry and physics were to his theology. It is argued that Faraday was unable to secularize his concept of force by breaking the ties between his physics and his theology of nature. Examination of his basic assumptions also (...) explains Faraday's failure to quantify his principle of conservation of force, his rejection of mechanical concepts of force and energy, and his early attempt to develop a wave-model for the conversion and transmission of electricity, magnetism, light and heat.

The Sense Complexity Dataset (SeCoDa) provides a corpus that is annotated jointly for complexity and word senses. It thus provides a valuable resource for both word sense disambiguation and the task of complex word identification. The intention is that this dataset will be used to identify complexity at the level of word senses rather than word tokens. For word sense annotation SeCoDa uses a hierarchical scheme that is based on information available in the Cambridge Advanced Learner’s Dictionary. This way we (...) can offer more coarse-grained senses than directly available in WordNet. (shrink)

Case studies of diverse scientific fields show how scientists use a range of resources to generate new interpretative models and to establish their plausibility as explanations of a domain. They accomplish this by manipulating imagistic representations in particular ways. I show that scientists in different domains use the same basic transformations. Common features of these transformations indicate that general cognitive strategies of interpretation, simplification, elaboration, and argumentation are at work. Social and historical studies of science emphasize the diversity of local (...) contexts of practice. However, the existence of common strategies shows that this diversity masks an important repertoire of cognitive strategies. Scientists use this repertoire to adapt their representations to meet the cognitive demands of different contexts of practice. This paper considers the implications of this finding for the notion of scientists as cognitive agents in distributed knowledge-producing systems. (shrink)

In June 1849 William Thomson wrote to Michael Faraday suggesting that the concept of a uniform magnetic field could be used to predict the motions of small magnetic and diamagnetic bodies. In his letter Thomson showed how Faraday's lines of magnetic force could represent the effect of the ‘conducting power’ for magnetic force of matter in the region of magnets. This was Thomson's extension to magnetism of an analogy between the mathematical descriptions of the distribution of static electricity and of (...) the diffusion of heat through uniform bodies. In 1850 Faraday published his first comprehensive theory of the magnetic properties of matter. He explained the behaviour of matter in the field by four assumptions: that matter has a specific disturbing effect on the normal distribution of lines of magnetic force; that this effect depends on its ability to conduct or transmit the magnetic action; and that material bodies tend to move so as to cause the least possible disturbance of the lines from their normal distribution. Faraday also assumed that diamagnetics transmit magnetic action less well than empty space, while paramagnetics transmit it more readily than space. This implied that space must have a specific conductivity between that of paramagnetic and diamagnetic materials. In order to preserve a distinction between matter and space Faraday defined ‘matter’ as either the source of action or as a conductor which is able to influence the lines of action; space was the absence of such powers. While space could conduct, it differed from matter in that it could neither originale lines of force nor influence their course and distribution. (shrink)
