  • The World Wide Web doubles in size roughly every 2–3 months and dramatic claims are made about the effectiveness of Web‐based commercial efforts. The centrality of non‐price mechanisms of differentiation to the perception, enjoyment and ease of use felt using websites is acknowledged but the only statistically rigorous studies of factors such as form and content have been conducted within a universalist paradigm of aesthetics. This paper reports on an interactionist approach to web aesthetics involving an analysis of 60 male‐ and female‐produced websites. The analysis reveals statistically significant differences between the male‐ and female‐produced websites on 13 out of the 23 factors analysed. These differences span issues of navigation as well as linguistic and visual content. The paper argues that the appeal of websites can be maximised if they mirror the needs and interests of their target populations and that websites targeted at male or female dominated markets need to reflect the aesthetic diversity found in the male‐ and female‐produced websites analysed here. It also presents information on the demographics of the IT profession, showing that there is a potential imbalance between the percentage of women involved online and those involved in the IT profession. This suggests that the male domination of the IT profession could be a barrier to the effective mirroring of female Website preferences.

In the first three experiments, subjects felt solid geometrical forms and matched raised-line pictures to the objects. Performance was best in experiment 1 for top views, with shorter response latencies than for side views, front views, or 3-D views with foreshortening. In a second experiment with blind participants, matching accuracy was not significantly affected by prior visual experience, but speed advantages were found for top views, with 3-D views also yielding better matching accuracy than side views. There were no performance advantages for pictures of objects with a constant cross section in the vertical axis. The early-blind participants had lower performance for side and frontal views. The objects were rotated to oblique orientations in experiment 3. Early-blind subjects performed worse than the other subjects given object rotation. Visual experience with pictures of objects at many angles could facilitate identification at oblique orientations. In experiment 5 with blindfolded sighted subjects, tangible pictures were used as targets and as choices. The results yielded superior overall performance for 3-D views (mean, M = 74% correct) and much lower matching accuracy for top views as targets (M = 58% correct). Performance was highest when the target and matching viewpoint were identical, but 3-D views (M = 96% correct) were still far better than top views. The accuracy advantage of the top views also disappeared when more complex objects were tested in experiment 6. Alternative theoretical implications of the results are discussed.  相似文献

Children in the United States are exposed to considerable community violence that has been linked to child functioning. However, not all those exposed, experience negative outcomes. Recent research has focused on factors that “buffer” or protect children from negative consequences of violence exposure. The purpose of this investigation was to examine the potential buffering or moderating role of maternal acceptance in the relationship between community violence exposure and internalizing and externalizing problems. Subjects were 268 urban African American first graders. Community violence exposure was significantly related to symptoms of post-traumatic stress, but did not correlate with either internalizing or externalizing problems for all children, after control for demographics, maternal mental health, and general life stress. However, children's perceptions of maternal acceptance moderated the relationship between violence exposure and internalizing and externalizing problems which included being withdrawn, anxious-depressed, and demonstrating delinquent behavior. Children with the lowest levels of self-reported maternal acceptance were most impacted by community violence. In this sample of urban first graders, low levels of maternal acceptance placed children at greater risk for adverse outcomes associated with community violence exposure compared to moderate and high levels of maternal acceptance.  相似文献

The present study was designed to examine the processes by which grammatical gender is assigned during word production. French words varied in strength of sublexical cues, based on whether the word ending was typical for one gender rather than neutral about gender, and lexical cues, derived from the associated definite article being uninformative about gender for words beginning with a vowel, but informative for words beginning with a consonant. In Experiment 1, when native French speakers classified the gender of mentally evoked names of pictures, no effects of these cues were obtained. Experiment 2 used an improved methodology, with participants classifying the gender of words translated from English. English-speaking learners of French were influenced strongly by lexical and sublexical cues, while French speakers showed a weaker influence. However, for both speaker groups, words whose gender was classified slowly during recognition were also classified slowly during production, and error rates were similarly correlated across tasks. The conclusion was that gender is not equally available for all words once the associated “lemma” is accessed. Current models of language production may have to incorporate mechanisms allowing differential speed of access to gender information depending on a word’s formal properties.  相似文献

This article analyzes and critiques the construct of gender as a psychoanalytic and cultural category. Without succumbing to a nonpsychoanalytic notion of androgyny, the argument developed here challenges the assumption that an internally consistent gender identity is possible or even desirable. Beginning with the idea that, from an analytic perspective, the construct of “identity”; is problematic and implausible, because it denotes and privileges a unified psychic world, the author develops a deconstructionist critique of our dominant gender‐identity paradigm. It is argued that gender coherence, consistency, conformity, and identity are culturally mandated normative ideals that psychoanalysis has absorbed uncritically. These ideals, moreover, are said to create a universal pathogenic situation, insofar as the attempt to conform to their dictates requires the activation of a false‐self system.

An alternative, “decentered”; gender paradigm is then proposed, which conceives of gender as a “necessary fiction”; that is used for magical ends in the psyche, the family, and the culture. From this perspective, gender identity is seen as a problem as well as a solution, a defensive inhibition as well as an accomplishment. It is suggested that as a goal for analytic treatment, the ability to tolerate the ambiguity and instability of gender categories is more appropriate than the goal of “achieving”; a single, pure, sex‐appropriate view of oneself.  相似文献

The literature on brain activity in depression and anxiety is reviewed with an on highlighting discrepancies and inconsistencies. In particular, and posterior asymmetries have been reported for both depression anxiety, but the magnitude and direction of these asymmetries has been We propose that by identifying subtypes of depression and anxiety of these inconsistencies can be explained. In addition, we review suggesting that issues of comorbidity are important to consider in to account for regional brain activity in depression and anxiety.  相似文献

John Henry Newman's early nineteenth‐century monograph The Arians of the Fourth Century iterates and intensifies the anti‐Jewish rhetoric already conveyed by the Nicene trinitarian theology inaugurated by Athanasius of Alexandria in the fourth century. Invoking philosopher Judith Butler's analysis of the performative power of ‘hate speech’ not only to injure, but also to interpellate subjects who may be heard to ‘talk back’, the present article seeks to surface the subversive potentialities contained not only within Newman's text (read in its immediate historical context), but also within trinitarian discourse more generally. Zenobia, third‐century ruler of Palmyra, reviled by Newman as both a ‘Judaizer’ and an ancestor of ‘Arianism’ (i.e. anti‐trinitarian theology), serves in this article (as in Newman's text) as the privileged figure for an interpellated subject, at once ‘Jewish’ and ‘feminine’ (thus seductively ‘oriental'), that may be heard to give voice to the ‘insurrectionary’ counter‐speech harbored within the very discourse of Christian orthodoxy that seeks to suppress it.  相似文献

Abstract

The aim of this paper is to argue that psychological research on the work ethic, or work centrality, uses too narrow a focus for understanding shifts in behaviour and attitudes over time. The appropriate unit of analysis is activity. Working is a subcategory of this larger unit. Six areas of activity are distinguished: education and training in early life, paid tasks or work, updating education throughout life, unpaid tasks or voluntary activity, education of the third age, and active or passive leisure. Historical, sociological, and anthropological evidence is reviewed and related to the psychological analysis of the meaning of working. It emerges that work is a controversial topic; it is extensively praised by some and condemned by others. Few would deny that paid work is a necessary way of obtaining basic and supplementary human requirements under present-day circumstances, but the differential conditions and constraints under which it is carried out are not always accepted as a necessary corollary. Is paid work a necessary or a desirable means of obtaining a standard of living? The answer depends on whether paid work is seen in isolation or as a subsystem of a wider range of activities which together result in a fulfilling life.  相似文献

Theory of mind (ToM) development, assessed via ‘litmus’ false belief tests, is severely delayed in autism, but the standard testing procedure may underestimate these children's genuine understanding. To explore this, we developed a novel test involving competition to win a reward as the motive for tracking other players' beliefs (the ‘Dot‐Midge task’). Ninety‐six children, including 23 with autism (mean age: 10.36 years), 50 typically developing 4‐year‐olds (mean age: 4.40) and 23 typically developing 3‐year‐olds (mean age: 3.59) took a standard ‘Sally‐Ann’ false belief test, the Dot‐Midge task (which was closely matched to the Sally‐Ann task procedure) and a norm‐referenced verbal ability test. Results revealed that, of the children with autism, 74% passed the Dot‐Midge task, yet only 13% passed the standard Sally‐Ann procedure. A similar pattern of performance was observed in the older, but not the younger, typically developing control groups. This finding demonstrates that many children with autism who fail motivationally barren standard false belief tests can spontaneously use ToM to track their social partners’ beliefs in the context of a competitive game.  相似文献
