This paper discusses some of the anthropological andphilosophical features of the use of self-managementplans by patients with a chronic disease, focusing onpatients with asthma. Characteristics of thistechnologically mediated form of self-care arecontrasted with the work of Mauss and Foucault on bodytechniques and techniques of self. The similaritiesand differences between self-management of asthma andFoucault's technologies of self highlight some of theways in which self-management contributes tomodifications in the definitions of patients andphysicians. Patients, in measuring their lungfunction, first come to rely on measurements more thanon felt disturbances, but next, felt disturbancesbecome modified by previous measurements. Physicians,on the other hand, see their role changed from expertto being a participant in a joint treatment. It isargued that the concept of agency is more appropriatefor describing the advantage of self-management forpatients than autonomy. 相似文献

Diagnostic devices do more than just passively register facts. They intervene in the situations in which they are put to use. The question addressed here is what this general remark may imply in specific cases. To answer this question a specific case is being analysed: that of the blood sugar measurement device that people with diabetes may use to monitor their own blood sugar levels. This device not only allows the patients concerned to better approach normal blood sugar levels, but alters what counts as normal in the first place. Using the device may shift people's attention away from their physical sensations towards the numbers measured, but it may also help them to increase their own physical self-awareness. Self-monitoring finally (something that the devices have made possible) makes patients less dependent on professionals, but it requires them to engage in self-disciplining and binds them to the outcomes of their measurement activities: their own blood sugar levels. 相似文献

Previous research has demonstrated that it is possible to induce biases in the interpretation of ambiguous text passages by training. Participants consistently trained to interpret emotionally ambiguous passages in either a negative or positive direction show training-congruent effects when presented with new ambiguous material. These training effects are demonstrated by participants' subsequent recognition ratings for disambiguating sentences, which represent both possible meanings of the novel ambiguous test passages. In this series of experiments, we investigated the durability of these training effects over time spans of up to 1 day and found them to be robust. The findings encourage us to believe that induced biases may serve as a useful analogue to those observed clinically. 相似文献

In this paper, we discuss the weakness of current action languages for sensing actions with respect to modeling domains with
multi-valued fluents. To address this problem, we propose a language with sensing actions and multi-valued fluents, called
AMK, provide a transition function based semantics for the language, and demonstrate its use through several examples from the
literature. We then define the entailment relationship between action theories and queries in AMK, denoted by ⊧AMK, and discuss some properties about AMK. 相似文献

Nanotechnology — A new field of ethical inquiry? 总被引:2,自引:0,他引:2
Grunwald A 《Science and engineering ethics》2005,11(2):187-201
Parallel to the public discussion on the benefits and risks of nanotechnology, a debate on the ethics of nanotechnology has
begun. It has been postulated that a new “nano-ethics” is necessary. In this debate, the — positive as well as negative —
visionary and speculative innovations which are brought into connection with nanotechnology stand in the foreground. In this
contribution, an attempt is made to discover new ethical aspects of nanotechnology in a more systematic manner than has been
the case. It turns out that there are hardly any completely new ethical aspects raised by nanotechnology. It is much rather
primarily a case of gradual shifts of emphasis and of relevance in questions which, in principle, are already known and which
give reason for ethical discussions on nanotechnology. In a certain manner, structurally novel ethical aspects arise through
the important role played by visions in the public discourse. New questions are also posed by the fact that previously separate
lines of ethical reflection converge in the field of nanotechnology. The proposal of an independent “nano-ethics”, however,
seems exaggerated. 相似文献

This study examined the effect of age and practice on the structure of children's force variability to test the information processing hypothesis that a reduction of sensorimotor system noise accounts in large part for age-related reductions in perceptual-motor performance variability. In the study, 6-year-olds, 10-year-olds, and young adults practiced on 5 consecutive days (15 trials/day), maintaining for 15-s trials a constant level of force (5 or 25% of maximum voluntary contraction) against an object using a pinch grip (thumb and index finger). With increasing age, the amount of force error and variability decreased, but the sequential structure of variability increased in irregularity. With practice, children reduced the amount of variability by changing the structure of the force output so as to be more similar to that of their older counterparts. The findings provide further evidence that practice-driven changes in the structure of force output, rather than a decline in the amount of white noise, largely account for age-related reductions in the amount of force variability. 相似文献

Patients with generalized social phobia (GSP, N=33) and matched community controls (N=31) engaged in a social interaction that was constructed to go well, and then received feedback that framed social cues reflecting either the absence of negative outcomes or the presence of positive outcomes. Following feedback that framed positive social cues, the GSP group predicted they would experience more anxiety in a subsequent interaction than did non-phobic controls. In contrast, following feedback framing the absence of negative outcomes, the GSP group did not differ from controls in their anxiety predictions. The results demonstrated that framing paradigms and methods can be usefully applied to the study of cognitive processes in social phobia and indicated that research to examine how GSP patients process specific types of social information is needed. 相似文献

Anxiety and selective attention in obsessive-compulsive disorder 总被引:2,自引:0,他引:2
Recently, there has been increasing evidence for information-processing deficits in individuals with obsessive-compulsive disorder (OCD). While impairments in selective attention have been identified to be central to the symptomatology of OCD, the role that situational anxiety plays in attentional processes has not been fully explored. Previous research findings were limited to tasks containing anxiety-relevant materials, only permitting for the evaluation of the impact of anxiety on simultaneous cognitive processing. Furthermore, it has not yet been determined whether the impact of anxiety is limited to selective attention or is indicative of a more general cognitive impairment. This study was designed to examine the role that situational anxiety plays in selective attention impairments. OCD participants and controls were presented with an anxiety producing statement and a neutral statement, followed by the Stroop Task. Results indicated that situational anxiety plays a significant role in the performance of tasks that require selective attention in OCD. A significant deterioration was detected in performance on selective attention tasks for the OCD participants after confronting anxiety-provoking scenarios, as compared to neutral scenarios. Anxiety did not impair performance on simple reading tasks. Possible explanations are discussed. 相似文献

Four studies tested the application of to the drawing domain. In particular, we tested her claim that young children are inhibited in their attempts at changing their graphic representations (representational change) due to being constrained by the order in which the elements of the representation are drawn (procedural rigidity). The first study required 60 children (4- to 6-year-olds and an older comparison group of 8-year-olds) to make three drawings of a familiar and novel topic. From these drawings each child was measured for procedural rigidity. In a further drawing the child was asked to modify their usual representation of each topic. Regression analyses revealed procedural rigidity levels were not predictive of manipulation performance. A second study, testing 75 4- to 6-year-olds and a third study, testing 30 3- to 4-year-olds, revealed that when young children were specifically asked to manipulate rigid sub-procedures on a familiar topic they were indeed able to do so. Finally, a fourth study (testing 40 5-year-olds and 40 8-year-olds) removed the notational trace in drawing (a possible aid for procedural interruption) but this still produced no evidence of a relation between procedural rigidity and representational change. We suggest how the concept of procedural rigidity might be re-interpreted for the drawing domain so that the RR model can remain as a domain-general theory of cognitive development. We also suggest the development of information processing may be crucial for flexibility in drawing. 相似文献
