This paper reports on the research activities performed by the Pictorial Computing Laboratory at the University of Rome, La Sapienza, during the last 5 years. Such work, essentially is based on the study of humancomputer interaction, spans from metamodels of interaction down to prototypes of interactive systems for both synchronous multimedia communication and groupwork, annotation systems for web pages, also encompassing theoretical and practical issues of visual languages and environments also including pattern recognition algorithms. Some applications are also considered like e-learning and collaborative work. 相似文献

Three experiments were carried out to investigate the internal structure of a rectangular frame to test Arnheim's (1974 Art and Visual Perception, 1988 The Power of the Center) proposals about its 'structural skeleton'. Observers made subjective ratings of how well a small probe circle fit within a rectangle at different interior positions. In experiment 1, ratings of 77 locations were highest in the center, decreased with distance from the center, greatly elevated along vertical and horizontal symmetry axes, and somewhat elevated along the local symmetry axes. A linear regression model with six symmetry-related factors accounted for 95% of the variance. In experiment 2 we measured perceived fit along local symmetry axes versus global diagonals near the corners to determine which factor was relevant. 2AFC probabilities were elevated only along the local symmetry axes and were higher when the probe was closer to the vertex. In experiment 3 we examined the effect of dividing a rectangular frame into two rectangular 'subframes' using an additional line. The results show that the primary determinant of good fit is the position of the target circle within the local subframes. In general, the results are consistent with Arnheim's proposals about the internal structure of a rectangular frame, but an alternative interpretation is offered in terms of the Gestalt concept of figural goodness. 相似文献

In plants, numerous parameters of both biotic and abiotic environments are continuously monitored. Specialized cells are evolutionary-optimized for effective translation of sensory input into developmental and motoric output. Importantly, diverse physical forces, influences, and insults induce immediate electric responses in plants. Recent advances in plant cell biology, molecular biology, and sensory ecology will be discussed in the framework of recently initiated new discipline of plant sciences, namely plant neurobiology. 相似文献

In this paper the argument from coherence is submitted to a critical analysis. First, it is argued to be a complex form of
coordinative argumentation, structured on various argumentative levels. Then, using the pragma-dialectical theory of argumentation
a distinction is brought out between two basic forms of the argument from coherence: in one use this argument occurs as a
sequence of two symptomatic arguments; in the other use we have a main symptomatic argument supported by a subordinate pragmatic
argument. Finally, from an evaluative point of view it is assessed whether the argument from coherence can be found acceptable
as a tool for settling disputes. It is claimed that in general, we can welcome this argumentative structure as sound and fully
acceptable provided that we are aware of the interpretative discretion its use implies.
A preliminary version of this essay was presented at the symposium organised by the Department of Speech Communication, Argumentation
Theory, and Rhetoric at the University of Amsterdamon the 27/02/04. I wish to express my indebtedness to Dora Achourioti,

Cyber-bullying represents a form of verbal or psychological aggression, carried out intentionally and repeatedly, and perpetuated using digital devices that has negative consequences on the health and well-being of adolescents. This phenomenon is prevented by contextual and dispositional factors. For this reason, our study investigated both these factors, specifically, the role of the perceived class cohesion in presence of vulnerability factors, that is, low levels of positivity. The results collected on a sample of 689 high school students (Mage = 17.3) suggest that the association between perceived class cohesion and victimisation was moderated by positivity. When young people with low positivity perceived low levels of social cohesion in the group, they experienced more cyberbullying victimisation. However, when high levels of perceived group cohesion were present, these experiences were reduced, regardless of their level of positivity. These results underline the importance of building a positive climate in the class group to prevent cyber-bullying in adolescence, especially for the most vulnerable individuals. 相似文献

Organizational identification has been linked to both positive behavior and negative behavior at work. Based on theory and research that suggest that for many organizational behaviors, team identification may be a more important influence than organizational identification, we advance a research model proposing that team identification, more than organizational identification, predicts counterproductive work behavior and organizational citizenship behavior and is the more important mediator of the influence of communication climate (CC) and perceived external prestige (PEP) on these outcomes. This research model was tested in a survey of N = 300 employees of four Italian organizations from different sectors. Results show that team identification, but not organizational identification, predicts counterproductive behavior and citizenship behavior and mediates the influence of CC and PEP. To enhance team identification for sustaining positive voluntary behavior at work, two possible strategies could be considered: improving perceived external prestige and promoting a good communication climate. 相似文献
