Background  In the last 30 years, there has been little innovation in workstations. The desktop metaphor has become the standard user interface, with its pros (e.g., ease of learning) and cons (e.g., interaction constraints for skilled users, lack of context awareness). Objectives  In this paper, we present itsme, an Italian initiative to design the next-generation workstation. Interaction design is the basis of the project, as well as the involvement of a wide community of contributing users. Results  The early design phases of the project led to the definition of a new metaphor for personal computing, based on stories and venues. The metaphor is being adopted for the development of a novel front-end for the Linux operating system, aimed at fulfilling the needs and desires of knowledge workers.

This research examined relationships between parental age, education, family size, length of residence in Canada, dyad type (same-sex parent-adolescent dyad versus opposite-sex parent-adolescent dyad) and immigrant parents’ perceptions of assimilative behaviours that adolescents are likely to display as a result of their involvement in the Canadian school system. An ethnically mixed sample of 36 parents and their adolescents responded to a questionnaire that solicited ratings of the degree of acceptability of prototypical assimilative adolescent behaviours. Analysis of Variance indicated that the match or mismatch between the sex of the parent and adolescent did not affect behavior ratings. Multiple Regression Analyses revealed that parental education was the only variable that significantly predicted parental approval or disapproval of adolescents’ behavioral shifts towards Western norms.  相似文献

This study examined the effects of climbing ladders, wall bars, perches, and ropes in changing students' attitudes and emotions associated with sport climbing. The tasks were part of a physical education instructional curriculum of primary schools in Italy. Boys and girls (N = 80), ages 10 to 11 years, were involved in a 10-lesson intervention during their curricular lesson. Participants were from six normal classes ranging in size from 16 to 18 children. Three classes were assigned randomly to an experimental group and the other three to a control group. The experimental group performed challenging climbing tasks, while the control group engaged in other physical activities. Analysis of variance indicated that scores on the Climbing Pictures Test differed significantly after the intervention, with children in the experimental group scoring lower on avoidance of climbing situations and higher on positive emotions.  相似文献

The authors studied a representative Canadian cohort from the National Longitudinal Study of Children and Youth at 3 points in time, when the participants were aged 10-11 years (n = 2,147), 12-13 years (n = 1,976), and 14-15 years (n = 1,762). The presence of parent-related adversity appeared detrimental to young people's emotional and behavioral competence. Parents' self-reports of adversity predicted children's self-reports of their own behavioral functioning 2 years later. The authors identified parenting quality and social support as independent resource variables for young people's competence, rather than protective variables in the face of parent-related adversity. Latent variable path analyses suggested the increasing value of both resource variables over time for all young people.  相似文献

The bilateral intranigral infusion of 1 micromol 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) in adult male Wistar rats caused a specific and partial loss of substantia nigra pars compacta (SNc) dopamine neurons, a partial depletion of striatal dopamine, and a deficit to learn the intra-maze cued version of the Morris water maze. Pre-training the SNc rats in the spatial version of the water maze or simply maintaining the animals on the water maze platform reversed this deficit. This improvement was even observed when the order of the extra-maze cues presented to the rats during pre-training of the spatial version was changed during training of the intra-maze cued version. However, this deficit was not reversed either by maintaining the animals on the platform if the spatial cues were surrounded and covered with a curtain or by swimming sessions in the maze without the escape platform and the curtain. These findings suggest that none of the following elements alone, learned during the spatial task pre-training, could help SNc rats learn the intra-maze cued task: improvement of swimming skills or knowledge of the existence of the escape platform; distance between the platform and the border of the pool; location of a particular extra-maze cue; relations among extra-maze cues. However, the simultaneous presence of the escape platform and extra-maze cues (irrespective of their relational configuration) during the pre-training sessions proved to be necessary for this improving effect to occur.  相似文献

Modern politics is becoming increasingly personalized. The personal qualities of political candidates, in fact, account for a considerable amount of the variance in the candidate preference of voters, often more than the political issues in their electoral programs. Despite the emphasis that both the media and campaign leaders place on the ways in which the personalities of politicians are portrayed, people tend to view the personalities of politicians in remarkably simple ways. Here we show that, although people tend to use five personality dimensions to characterize their own personalities, they rely upon only two dimensions to characterize the personalities of politicians. This finding holds across countries (i.e., Italy and the US), and across political figures (i.e., Prodi and Berlusconi in Italy, and Bush and Kerry in the US). The two factors obtained from evaluations of Prodi, Berlusconi, and Kerry were respectively a blend of Energy/Extraversion and Openness and a blend of Friendliness, Conscientiousness, and Emotional Stability. The two factors obtained from evaluations of the US president, though, were respectively a blend of Openness, Conscientiousness, and Friendliness, and a blend of Energy/Extraversion, Emotional Stability, and Friendliness. Thus, the present study is novel in suggesting that while the personalities of politicians may be reduced by voters, they are not always reduced to the same basic factors. Alternative explanations of this “simplification effect” are discussed.  相似文献

We present evidence that (a) at least some components of the reading process are serial and (b) pseudoword reading is affected by lexical knowledge, even in a transparent orthographic system like Italian. Pseudowords deriving from five-letter words by changing either the first or the fourth letter were presented for reading aloud. Results showed an effect of the position of the diverging letter: Early diverging pseudowords were read more slowly than late diverging pseudowords. The dual-route cascaded (DRC) model (Coltheart, Rastle, Perry, Langdon, & Ziegler, 2001) successfully simulated the behavioural data.  相似文献

Transplantation continues to push the frontiers of medicine into domains that summon forth troublesome ethical questions. Looming on the frontier today is human facial transplantation. We develop criteria that, we maintain, must be satisfied in order to ethically undertake this as-yet-untried transplant procedure. We draw on the criteria advanced by Dr. Francis Moore in the late 1980s for introducing innovative procedures in transplant surgery. In addition to these we also insist that human face transplantation must meet all the ethical requirements usually applied to health care research. We summarize the achievements of transplant surgery to date, focusing in particular on the safety and efficacy of immunosuppressive medications. We also emphasize the importance of risk/benefit assessments that take into account the physical, aesthetic, psychological, and social dimensions of facial disfiguration, reconstruction, and transplantation. Finally, we maintain that the time has come to move facial transplantation research into the clinical phase.  相似文献

The Fear Survey Schedule-III (FSS-III) was administered to a total of 5491 students in Australia, East Germany, Great Britain, Greece, Guatemala, Hungary, Italy, Japan, Spain, Sweden, and Venezuela, and submitted to the multiple group method of confirmatory analysis (MGM) in order to determine the cross-national dimensional constancy of the five-factor model of self-assessed fears originally established in Dutch, British, and Canadian samples. The model comprises fears of bodily injury-illness-death, agoraphobic fears, social fears, fears of sexual and aggressive scenes, and harmless animals fears. Close correspondence between the factors was demonstrated across national samples. In each country, the corresponding scales were internally consistent, were intercorrelated at magnitudes comparable to those yielded in the original samples, and yielded (in 93% of the total number of 55 comparisons) sex differences in line with the usual finding (higher scores for females). In each country, the relatively largest sex differences were obtained on harmless animals fears. The organization of self-assessed fears is sufficiently similar across nations to warrant the use of the same weight matrix (scoring key) for the FSS-III in the different countries and to make cross-national comparisons feasible. This opens the way to further studies that attempt to predict (on an a priori basis) cross-national variations in fear levels with dimensions of national cultures.  相似文献
