Alessandro Ferrara 《Res Publica》2011,17(4):377-383
This paper engages with Ferrajoli’s contribution to the philosophical debate on constitutional democracy and in particular
his conception of ‘structural entrenchment’, or the basis upon which one can defend the normativity of the Constitution as
‘higher law’, which can trump or limit legislation, without infringing democratic principles. Ferrajoli’s own understanding
of ‘structural entrenchment’ is compared to Rawls’s and Dworkin’s arguments in support of it. Ferrajoli’s position is neither
grounded on a philosophy of history, as in Rawls, nor on a version of moral realism, as for Dworkin, but on a formal understanding
of the nature of fundamental rights, and in a conception of democratic sovereignty as ‘joint ownership.’ 相似文献

This study evaluated the correspondence between measures of two competing theories of personality, the five-factor model as measured by the Big Five Questionnaire (BFQ), and Cloninger's psychobiological theory measured by the Temperament and Character Inventory-Revised (TCI-R). A sample of 900 Italian participants, balanced with respect to sex (393 men and 507 women), and representative of the adult population with respect to age (range 18 to 70 years; M = 39.6, SD = 15.7) completed the TCI-R and the Big Five Questionnaire. All TCI-R personality dimensions except Self-Transcendence were moderately correlated with one or more of the Big Five dimensions (from r = .40 to .61), and the two instruments showed areas of convergence. However, the differences outweighed the similarities, indicating that these current conceptualizations and measures of personality are somewhat inconsistent with each other. 相似文献

The value of λ is one of the main issues debated in international usability studies. The debate is centred on the deficiencies
of the mathematical return on investment model (ROI model) of Nielsen and Landauer (1993). The ROI model is discussed in order
to identify the base of another model that, respecting Nielsen and Landauer’s one, tries to consider a large number of variables
for the estimation of the number of evaluators needed for an interface. Using the bootstrap model (Efron 1979), we can take into account: (a) the interface properties, as the properties at zero condition of evaluation and (b) the probability
that the population discovery behaviour is represented by all the possible discovery behaviours of a sample. Our alternative
model, named Bootstrap Discovery Behaviour (BDB), provides an alternative estimation of the number of experts and users needed
for a usability evaluation. Two experimental groups of users and experts are involved in the evaluation of a website (). Applying the BDB model to the problems identified by the two groups, we found that 13 experts and 20 users are needed to
identify 80% of usability problems, instead of 6 experts and 7 users required according to the estimation of the discovery
likelihood provided by the ROI model. The consequence of the difference between the results of those models is that in following
the BDB the costs of usability evaluation increase, although this is justified considering that the results obtained have
the best probability of representing the entire population of experts and users. 相似文献

The current study explores the role of three components of working memory in age differences in an executive task, the Tower of London (TOL). The TOL task is sensitive to frontal lobe damage, and is widely used to measure planning ability. Dual tasks were used to test the involvement of the phonological loop (articulatory suppression), visuospatial buffer (pattern tapping), and central executive (random generation) in age effects on the TOL. Older adults showed greater reliance than young on domain-specific verbal and spatial memory components in performing the TOL. In terms of executive function, qualitatively different interference patterns were seen in young and old participants. However, the validity of using random generation tasks to assess executive function in older populations can be questioned. For older participants, performing the TOL loads all components of working memory, whereas for the younger participants the TOL more specifically loads executive functioning. 相似文献

In the late 1970s/early 1980s, Baddeley and colleagues conducted a series of experiments investigating the role of eye movements in visual working memory. Although only described briefly in a book (Baddeley, 1986), these studies have influenced a remarkable number of empirical and theoretical developments in fields ranging from experimental psychology to human neuropsychology to nonhuman primate electrophysiology. This paper presents, in full detail, three critical studies from this series, together with a recently performed study that includes a level of eye movement measurement and control that was not available for the older studies. Together, the results demonstrate several facts about the sensitivity of visuospatial working memory to eye movements. First, it is eye movement control, not movement per se, that produces the disruptive effects. Second, these effects are limited to working memory for locations and do not generalize to visual working memory for shapes. Third, they can be isolated to the storage/maintenance components of working memory (e.g., to the delay period of the delayed-recognition task). These facts have important implications for models of visual working memory. 相似文献

This paper introduces a perspective accounting for errors that may occur as a result of the human interaction with the three-dimensional (3D) space. Particularly, we are interested in errors that are caused by cognitively crossing the boundary between peripersonal and extrapersonal space. Several behavioural, neurophysiological, and neuropsychological perspectives are reviewed in order to develop the theoretical framework on which our ideas are founded. We argue that cognitively crossing the boundary implies switching from one frame of reference to another, which, as a consequence, implies specific costs. The results of five experiments (overall involving 76 participants) support our hypothesis, suggesting the existence of different action-oriented spatial frames of reference. 相似文献

The paper discusses the structure of non-verbal predication, with particular reference to the role of the copula. Differently from the main tenets of contemporary logico-philosophical and linguistic theories, a model of predication is proposed where the verbal component (specifically, tense information) is regarded as central in establishing the syntactic and semantic relation between a predicate and its subject. It is thus possible to recover some of the insights of the pre-Fregean analysis of predication. The proposed solution has a number of significant consequences for the structure to be assigned to non-verbal predication, in particular for the semantics of small clause constituents, where the predication is established without the copula. 相似文献

Visual similarity effects in immediate verbal serial recall 总被引:4,自引:0,他引:4

The role of visual working memory in temporary serial retention of verbal information was examined in four experiments on immediate serial recall of words that varied in visual similarity and letters that varied in the visual consistency between upper and lower case. Experiments 1 and 2 involved words that were either visually similar (e.g. fly, cry, dry; hew, new, few ) or were visually distinct (e.g. guy, sigh, lie; who, blue, ewe ). Experiments 3 and 4 involved serial recall of both letter and case from sequences of letters chosen such that the upper- and lower-case versions were visually similar, for example Kk, Cc, Zz, Ww , or were visually dissimilar, for example Dd, Hh, Rr, Qq . Hence in the latter set, case informationwas encoded interms of both the shape and the size of the letters. With both words and letters, the visually similar items resulted in poorer recall both with and without concurrent articulatory suppression. This visual similarity effect was robust and was replicated across the four experiments. The effect was not restricted to any particular serial position and was particularly salient in the recall of letter case. These data suggest the presence of a visual code for retention of visually presented verbal sequences in addition to a phonological code, and they are consistent with the use of a visual temporary memory, or visual "cache", in verbal serial recall tasks. 相似文献

Two domains of potential risk in relation to the cognitive-linguistic outcomes of preschool children of adolescent mothers were investigated: (1) interactive features of the mother—child relationship and (2) aspects of the demographic context of parenting. Sixty-nine adolescent mothers and their children participated in evaluations when the children were 13, 20, 30, and 44 months old. Results indicated that the cognitive-linguistic development of children of adolescent mothers was affected by both the mother—child relationship and cumulative index of demographic risk. Specifically, positive maternal affect, mother—child verbal reciprocity, mother—child interactive fit, and cumulative demographic risk all contributed to explaining difficulties in preschool cognitive and linguistic functioning in children of adolescent mothers. 相似文献
