Many activities of daily living require that we physically interact with one or more objects. Object manipulation provides an intriguing domain in which the presence and extent of manual asymmetries can be studied on a motor planning and a motor execution level. In this literature review we present a state of the art for manual asymmetries at the level of motor planning during object manipulation. First, we introduce pioneering work on grasp posture planning. We then sketch the studies investigating the (...) impact of future task demands during unimanual and bimanual object manipulation tasks in healthy adult populations. In sum, in contrast to motor execution, there is little evidence for hand-based performance differences in grasp posture planning. We discuss potential reasons for the lack of manual asymmetries in motor planning and outline potential avenues of future research. (shrink)

To revitalize nursing science, there is a need for a new approach to guide nurse scientists in addressing complex problems in health care. By applying theoretical concepts from a revolutionary philosopher of science, Paul K. Feyerabend, new nursing knowledge can be produced using creativity and pluralistic approaches. Feyerabend proposed that methods within and outside of science can produce knowledge. Despite the recognition of Feyerabendian philosophy within science, there is currently a lack of literature regarding the relevance of Feyerabendian philosophy for (...) nursing science. We aim to (a) describe and critique Feyerabendian concepts, (b) discuss the potential application of Feyerabendian philosophy for knowledge production within gerontological nursing and (c) describe theoretical possibilities for nurse scientists in using Feyerabendian philosophy to guide nursing knowledge development. We begin by introducing Feyerabend's life and his inspirations for his theoretical concepts, epistemological anarchism, theoretical pluralism and humanitarianism, and conclude by offering suggestions of how to apply Feyerabendian philosophy in nursing research.

This article focuses on Homers idea of reflexive rhetoric. The majority of Homeric deliberation scenes contain no deliberative calculi. One approach to this problem would be to generalize from the scenes where Odysseus uses deliberative calculi to those where he does not. One might argue, though, that data have to be transmitted to and outputted from a computer via interfaces, one where data are transformed into electrical impulses, and one where the output is printed as information. The deliberative calculus cannot (...) be the essential link between deliberation and persuasion, though it undoubtedly figures into the process of self-persuasion to the extent that it either explicitly or implicitly brings about a particular decision. In this perspective, the fact that Homer is frequently silent about deliberative calculi is irrelevant to the question of whether Odysseus persuades himself. The idea of Homeric rhetoric is alleged to pose the problem of anachronism. Moving toward an account of reflexive rhetoric allows to see in even greater detail the centrality of rhetoric to human condition.

This essay explores Johnstone's idea that "rhetoric is a wedge." In particular, it explores the place of this idea in Johnstone's philosophy of argument, the need to confront this idea with argument, and ways of confronting it with ad rem and ad hominem arguments.

The rhetorical structure of Vico’s pedagogy is shaped predominantly by the ars topica. While most would associate the ars topica with the classical Greek and Roman cultures, where theories of topoi predominate rhetorical theory and pedagogy, this essay shows that the ars topica in the rhetorical structure of Vico’s pedagogy must be heroic in nature, rather than classical. Embodied in the figure of Homer, the ars topica in Vico’s pedagogy stands beyond the technical consciousness of the classical world. The figure (...) of Homer stands for the imaginative poetic capacity to make figural connections and to escape the reduction of meaning to technical formulae. Such escape, for Vico, ensures the life and liberty of not only the individual mind but the civic realm. (shrink)

ABSTRACT In contemporary U.S. public discourse, calls for achieving equity abound. Many metrics now measure equity being achieved. I inquire into whether equity can be said to be achieved and still be equity. Inquiring as such leads me to excavating the menacing and actual cultural violence of developing such achievement. Simultaneously, this excavation shows the rhetoric of equity qua equity as a means of abolishing the conditions for that violence to take hold. I put forward that equity cannot be said (...) to be achieved without the conditions of possibility equity offers being colonized. If a commitment to antiviolence speaks, it cannot say, “Equity achieved.”. (shrink)

The relationships between captive primates and their caregivers are critical ones and can affect animal welfare. This study tested the effect of caregivers using chimpanzee behaviors or not, in daily interactions with captive chimpanzees. In the Chimpanzee Behavior condition the caregiver presented chimpanzee behaviors. In the Human Behavior condition the caregiver avoided using chimpanzee behaviors. The chimpanzees had individual patterns of response and had significant differences in their responses to each condition. These data are compared to a similar study conducted (...) at The Zoo Northwest Florida. Both groups of chimpanzees were sensitive and responsive to the differences in conditions. These data suggest ways to improve animal welfare. (shrink)

The leadership development industry regularly claims to aid in developing effective, ethical leaders, using 360-degree psychometric assessments as key tools for so doing. This paper analyses the effects of such tools on those subjected to and subjectivised by them from a Foucauldian perspective. We argue that instead of encouraging ethical leadership such instruments inculcate practices and belief systems that perpetuate falsehoods, misrepresentations and inequalities. ‘Followers’ are presumed compliant, malleable beings needing leaders to determine what is in their interests. Such techniques (...) pursue productivity and profitability, rather than ethical leadership. We examine the Multifactor Leadership Questionnaire, a widely used 360-degree tool that measures transformational leadership, as an illustrative case study to substantiate these criticisms. (shrink)

Conversational interactions depend on partners making contingent responses. This experiment examined the responses of five chimpanzees, Washoe, Moja, Tatu, Dar and Loulis, to four conversational conditions. Following the chimpanzee’s request, a human interlocutor either: complied with the request, provided an unrequested item or activity, refused to comply or did not respond to the request. The chimpanzees’ responses were contingent on the conversational input of the interlocutor. When their requests were satisfied, the chimpanzees most often ceased signing. However, when their requests (...) were misunderstood, refused or not acknowledged, the chimpanzees repeated and revised. This pattern of responses is comparable to patterns of conversational responses in human children. Keywords: chimpanzees; American Sign Language; requests; pragmatics; conversation; gesture; communication; Pan troglodytes. (shrink)

Speech act theory describes units of language as acts which function to change the behavior or beliefs of the partner. Therefore, with every utterance an individual seeks a communicative goal that is the underlying motive for the utterance’s production; this is the utterance’s function. Studies of deaf and hearing human children classify utterances into categories of communicative function. This study classified signing chimpanzees’ utterances into the categories used in human studies. The chimpanzees utilized all seven categories of communicative functions and (...) used them in ways that resembled human children. The chimpanzees’ utterances functioned to answer questions, request objects and actions, describe objects and events, make statements about internal states, accomplish tasks such as initiating games, protest interlocutor behavior, and as conversational devices to maintain and initiate conversation.

Proprioception is a crucial sensory modality involved in the control and regulation of coordinated movements and in motor learning. However, the extent to which proprioceptive acuity is influenced by local muscle fatigue is obscured by methodological differences in proprioceptive and fatiguing protocols. In this study, we used high resolution kinematic measurements provided by a robotic device, as well as both frequency and time domain analysis of signals captured via surface electromyography (sEMG) to examine the effects of local muscle fatigue on (...) wrist proprioceptive acuity in 16 physically and neurologically healthy young adults. To this end, participants performed a flexion/extension ipsilateral joint position matching test (JPM), after which a high-resistive robotic task was used to induce muscle fatigue of the flexor carpi radialis (FCR) muscle. The JPM test was then repeated in order to analyze potential changes in proprioceptive acuity. Results indicated that the fatigue protocol had a significant effect on movements performed in flexion direction, with participants exhibiting a tendency to undershoot the target before the fatigue protocol (-1.218°), but overshooting after the fatigue protocol (0.587°). In contrast, in the extension direction error bias values were similar before and after the fatigue protocol as expected (pre = -1.852°, post = -1.237°) and reflected a tendency to undershoot the target. Moreover, statistical analysis indicated that movement variability was not influenced by the fatigue protocol or movement direction. In sum, results of the present study demonstrate that an individual’s estimation of wrist joint displacement (i.e., error bias), but not precision (i.e., variability), is affected by muscular fatigue in a sample of neurologically and physically healthy adults.

Ormerod and Chronicle reported that optimal solutions to traveling salesperson problems were judged to be aesthetically more pleasing than poorer solutions and that solutions with more convex hull nodes were rated as better figures. To test these conclusions, solution regularity and the number of potential intersections were held constant, whereas solution optimality, the number of internal nodes, and the number of nearest neighbors in each solution were varied factorially. The results did not support the view that the convex hull is (...) an important determinant of figural attractiveness. Also, in contrast to the findings of Ormerod and Chronicle, there were consistent individual differences. Participants appeared to be divided as to whether the most attractive figure enclosed a given area within a perimeter of minimum or maximum length. It is concluded that future research in this area cannot afford to focus exclusively on group performance measures. (shrink)

This paper examines human planning abilities, using as its inspiration planning techniques developed in artificial intelligence. AI research has shown that in certain problems partial‐order planners, which manipulate partial plans while not committing to a particular ordering of those partial plans, are more efficient than total‐order planners, which represent all partial plans as totally ordered. This research asks whether total‐order planning and/or partial‐order planning are accurate descriptions of human planning, and if different populations use different planning techniques. Using a simple (...) planning task modeled after tasks designed in artificial intelligence we tested 7–8 year‐old children, 11–13 year‐old children, adult controls, and adults with damage to the prefrontal cortex. We found that adults and older children exhibited performance on planning tasks of varying complexity which matched that of artificial partial‐order planners, and that this pattern of performance did not vary with multiple presentations of the planning task. In contrast, young children and adults with damage to the prefrontal cortex exhibited performance matching that of artificial total‐order planners. This pattern of performance did vary, however, with multiple presentations of the planning task, with the young children and adults with cortical damage displaying aspects of total‐order planning. In a further study we found that adolescents who had sustained damage to the prefrontal cortex as children displayed two different patterns of performance; when measures of reaction time were analyzed they revealed a pattern of performance suggestive of partial‐order plan representations. However, analyses of the adolescents' protocols revealed a pattern of performance suggestive of total‐order plan representations. The significance of these results to psychology, neuroscience, and artificial intelligence are discussed. (shrink)

We reflect, using a vignette, on conceptual tensions and the value judgements that lie behind difficult decisions about whether or not the older person with dementia should return home or move into long-term care following hospital admission. The paper seeks, first, to expose some of the difficulties arising from the assessment of residence capacity, particularly around the nature of evaluative judgements and conceptual tensions inherent in the legal approach to capacity. Secondly, we consider the assessment of best interests around place (...) of residence, which demonstrates significant conceptual tensions. In addition, ‘best interests’ raise issues around the perception of risk and the perceptions of the family and crucially involve the notions of autonomy and trust. Finally, we not only gesture at some practical considerations based on insights from values-based medicine, but also make the suggestion that we require tighter functional assessments of residence capacity coupled with broader judgements about best interests.

In the current study we compared academic locus of control (ALoC) and perceived quality of academic life (PQAL) across three groups of university students: those without disabilities, those with attention deficit disorder or learning disabilities (ADD-LD), and those with other disabilities. Results showed no significant differences in ALoC scores, with each group reporting an internal ALoC. However, students with other disabilities (e.g., sensory, motor, chronic health, and/or mental health) reported significantly lower satisfaction with their overall quality of academic life than (...) students without disabilities. Applied implications are discussed along with recommendations for further research. (shrink)
