A defence of informational structural realism 总被引:2,自引:0,他引:2
Luciano Floridi 《Synthese》2008,161(2):219-253
This is the revised version of an invited keynote lecture delivered at the 1st Australian Computing and Philosophy Conference (CAP@AU; the Australian National University in Canberra, 31 October–2 November, 2003). The paper is divided into two parts. The first
part defends an informational approach to structural realism. It does so in three steps. First, it is shown that, within the
debate about structural realism (SR), epistemic (ESR) and ontic (OSR) structural realism are reconcilable. It follows that
a version of OSR is defensible from a structuralist-friendly position. Second, it is argued that a version of OSR is also
plausible, because not all relata (structured entities) are logically prior to relations (structures). Third, it is shown that a version of OSR is also applicable
to both sub-observable (unobservable and instrumentally-only observable) and observable entities, by developing its ontology
of structural objects in terms of informational objects. The outcome is informational structural realism, a version of OSR supporting the ontological commitment to a view of the world as the totality of informational objects dynamically
interacting with each other. The paper has been discussed by several colleagues and, in the second half, ten objections that
have been moved to the proposal are answered in order to clarify it further. 相似文献

Depth stratification in illusory-contour figures was studied by superimposing Kanizsa figures on heterogeneous backgrounds. Gaussian-noise textures were employed in two rating-scale experiments to explore observers' judgments of (i) illusory-contour clarity, (ii) brightness enhancement, and (iii) depth stratification. In experiment 1, depth stratification was found to be stronger in heterogeneous conditions. In experiment 2, texture coarseness was manipulated to determine how depth stratification is affected by linear elements of different sizes in the background, and to relate the variation to contour clarity and brightness enhancement. Results suggest that depth stratification is independent of contour clarity and brightness enhancement. Preliminary novel observations on illusory-contour formation are reported. 相似文献

The authors investigated whether impaired gait and dual-task performances are associated with specific cognitive domains among older people with preserved cognition (PC), mild cognitive impairment (MCI), and mild Alzheimer's disease (AD). The sample comprised 40 older adults with PC, 40 with MCI, and 38 with mild AD. The assessment consisted of gait (measured by 10-m walk test and Timed Up and Go Test [TUGT]), dual task (measured by TUGT associated with a cognitive-motor task of calling a phone number), and cognition (domains of the Addenbrooke Cognitive Examination–Revised and Frontal Assessment Battery [FAB]). For data analysis, the Pearson product-moment correlation and the backward stepwise linear regression were conducted. Language, fluency, and visuospatial domains predicted the 10-m walk test measure specifically in PC, MCI, and AD groups. Only the visuospatial domain was independently associated with the TUGT measure in the MCI and AD groups. FAB score, language domain, and FAB score and fluency domain were the strongest predictors for the isolated cognitive-motor task measure in the PC, MCI, and AD groups, respectively. The visuospatial domain was independently associated with the dual-task test measure in all 3 groups. The study findings demonstrate the influence of specific cognitive domains in daily mobility tasks in people with different cognitive profiles. 相似文献

Destination memory, a memory component allowing the attribution of information to its appropriate receiver (e.g., to whom did I lend my pen?), is compromised in normal aging. The present paper investigated whether older adults might show better memory for older destinations than for younger destinations. This hypothesis is based on empirical research showing better memory for older faces than for younger faces in older adults. Forty-one older adults and 44 younger adults were asked to tell proverbs to older and younger destinations (i.e., coloured faces). On a later recognition test, participants had to decide whether they had previously told some proverb to an older/younger destination or not. Prior to this task, participants reported their frequency of contact with other-age groups. The results showed lower destination memory in older adults than in younger adults. Interestingly, older adults displayed better memory for older than for younger destinations. The opposite pattern was seen in younger adults. The low memory for younger destinations, as observed in older adults, was significantly correlated with limited exposure to younger individuals. These findings suggest that for older adults, the social experience can play a crucial role in the destination memory, at least as far as exposure to other-age groups is concerned. 相似文献

Interpersonal competence is crucial to human life, and poor social functioning is a typical feature of various psychopathological conditions. Given the relevance of the construct, increasing attention has recently been paid to the Interpersonal Competence Questionnaire (ICQ; Buhrmester et al. 1988), a 40-item self-report measuring five domains of interpersonal competence. To provide additional data on the cross-cultural adaptability of the ICQ, we developed an Italian version and investigated its psychometric properties with two independent student samples. Respondents were mostly women (about three quarters), ranging in age from 18 to 57. Study 1 (n?=?408) tested factor structure, internal consistency, and convergent validity. Study 2 (n?=?59) investigated test-retest reliability. Taken together, the results of both these studies provided support for the cross-cultural applicability of the ICQ, and revealed interesting associations between interpersonal competence and constructs such as well-being, emotion dysregulation and empathy. 相似文献

The capacity to collect and analyse data is growing exponentially. Referred to as ‘Big Data’, this scientific, social and technological trend has helped create destabilising amounts of information, which can challenge accepted social and ethical norms. Big Data remains a fuzzy idea, emerging across social, scientific, and business contexts sometimes seemingly related only by the gigantic size of the datasets being considered. As is often the case with the cutting edge of scientific and technological progress, understanding of the ethical implications of Big Data lags behind. In order to bridge such a gap, this article systematically and comprehensively analyses academic literature concerning the ethical implications of Big Data, providing a watershed for future ethical investigations and regulations. Particular attention is paid to biomedical Big Data due to the inherent sensitivity of medical information. By means of a meta-analysis of the literature, a thematic narrative is provided to guide ethicists, data scientists, regulators and other stakeholders through what is already known or hypothesised about the ethical risks of this emerging and innovative phenomenon. Five key areas of concern are identified: (1) informed consent, (2) privacy (including anonymisation and data protection), (3) ownership, (4) epistemology and objectivity, and (5) ‘Big Data Divides’ created between those who have or lack the necessary resources to analyse increasingly large datasets. Critical gaps in the treatment of these themes are identified with suggestions for future research. Six additional areas of concern are then suggested which, although related have not yet attracted extensive debate in the existing literature. It is argued that they will require much closer scrutiny in the immediate future: (6) the dangers of ignoring group-level ethical harms; (7) the importance of epistemology in assessing the ethics of Big Data; (8) the changing nature of fiduciary relationships that become increasingly data saturated; (9) the need to distinguish between ‘academic’ and ‘commercial’ Big Data practices in terms of potential harm to data subjects; (10) future problems with ownership of intellectual property generated from analysis of aggregated datasets; and (11) the difficulty of providing meaningful access rights to individual data subjects that lack necessary resources. Considered together, these eleven themes provide a thorough critical framework to guide ethical assessment and governance of emerging Big Data practices. 相似文献

Destination memory refers to the recall of the destination of previously relayed information, and source memory refers to the recollection of the origin of received information. We compared both memory systems in Huntington's disease (HD) participants. For this, HD participants and healthy adults had to put 12 items in a black or a white box (destination task), and to extract another 12 items from a blue or a red box (source task). Afterwards, they had to decide in which box each item had previously been deposited (destination memory), and from which box each item had previously been extracted (source memory). HD participants showed poorer source as well as destination recall performance than healthy adults in the proposed tasks. Correlation analysis showed that destination recall was significantly correlated with episodic recall in HD participants. Destination memory impairment in HD participants seems to be considerably influenced by their episodic memory performance. 相似文献

This study aimed to evaluate a peripheral serotonergic marker, 3H-imipramine (3H-IMI) binding to platelet membranes, in a group of severely aggressive subjects (A), institutionalized since childhood for mental retardation, as compared with suicide attempters (S) and healthy controls (H). The maximum binding capacity of 3H-IMI to platelet membranes was statistically lower in (A) and (S) than in (H). In addition, a statistically significant difference was observed between the Bmax values of aggressive subjects and those of suicide attempters. No changes in the dissociation constant (Kd) of IMI binding were observed. These data provide further supporting evidence for the hypothesis of an abnormality of the 5HT system in aggressive behaviour and suggest that such an abnormality, as reflected by platelet markers, is more severe in suicide attempters. © 1993 Wiley-Liss, Inc. 相似文献

In an attempt to study the relationship between ageing and personality and the morningness-eveningness dimension two experiments were carried out. In experiment I, an Italian version of the Morningness-Eveningness Questionnaire (MEQ) was administered to 435 Ss ranging in age from 20 to 79 yr, and divided in to six age groups. In comparison with younger people older S tended to display greater Morningness-Eveningness scores. These results suggest that ageing relates to a shifting toward morningness. In Experiment II the Eysenck Personality Questionnaire (EPQ) and the MEQ were administered to 233 Ss (20–29 yr). Morning-types had significantly higher N scores and tended to be insignificantly more introverted. Evening-types had significantly higher N scores and tended to be insignificantly more extraverted. The present findings are consistent with reports of a tendency for morning-types to be introverted and for evening-types extraverted. However, they do provide some evidence of individual differences on the neuroticism and psychoticism dimensions of personality between the two diurnal types. 相似文献
