Interaction design of mobile systems is a complex activity because it requires considering new usability and user experience
aspects in order to exploit the peculiar characteristics of mobile devices, such as their pervasive and ubiquitous nature.
This paper discusses issues about designing, developing and evaluating mobile systems. Italy has a rich cultural heritage,
and the focus in this study is on the design of systems that enable interactive exploration of historical sites, not only
for enhancing the user experience but also for learning purposes. The experience of the researchers at the Interaction, Visualisation
and Usability lab, University of Bari, Italy, in designing a mobile learning system, called Explore!, which supports young
students learning ancient history during a visit to archaeological parks, is reported. The evaluation of Explore! through
systematic field studies shows that the adopted approach is able to transform the visit to archaeological parks into a more
complete and culturally rich experience. 相似文献

Identifying and analyzing the construction and effectiveness of offensive plays in basketball by using systematic observation 总被引:1,自引:0,他引:1

In the field of sports research, there is a growing need for the rigorous collection of data that provide empirical evidence
about the complex reality they refer to. Although sports psychology research has advanced considerably in recent years, in
both extent and quality, one area of research that remains relatively unexplored is the dynamics of the sports group and the
influence of the group on its members (George & Feltz, 1995; Widmeyer, Brawley, & Carron, 1992). Key aspects in this regard
include the presence of regularities that are not detectable through visual inference or traditional methods of data analysis,
the lack of standard observation instruments, and, assuming priority, the need to develop powerful, computerized coding systems,
all of which must form part of an approach that is suitable for natural and habitual contexts. The present study is part of
a broader research project concerning ACB teams (first Spanish basketball division) and considers the interaction context
before teams try to score (where this is understood as how teams create scoring opportunities) as the core aspect that links
team play. This investigation proposes a new model of analysis for studying the effectiveness and construction of offensive
basketball plays in order to identify their outcomes, thus providing coaches with an important device for improving or consolidating
them. 相似文献

We investigated the effects of familiarity on person perception. We predicted that familiarity would increase non‐analytic processing, reducing attention to and the impact of individuating information, and increasing the impact of category labels on judgments about a target person. In two studies participants read either incriminating or exculpatory individuating information about a defendant in a criminal case and made judgments of guilt. In Study 1, participants were subliminally exposed to the defendant's photo, another matched photo, or no photo before seeing the evidence. Participants familiar with the defendant's photo both processed and used the individuating information less. In Study 2, participants were subtly made familiar or not with the incriminating and exculpatory information itself, and the defendant was described either as a priest or as a skinhead. Familiarity with the information reduced attention to its content and also tended to increase reliance on category information in guilt judgments. Copyright © 2006 John Wiley & Sons, Ltd. 相似文献

Based on an analysis of the articles in this special issue, the authors propose five operating principles for systems change work. These principles are: clarifying the purpose of the systems change; identifying whether the change is one to an existing system or the change is to create a new system; conceptualize the work as systems change from the beginning; use an eclectic approach; and be open to opportunities that emerge while also undertaking forma analysis to identify leverage points. The authors argue that the time is now ripe to develop such principles and encourage community change agents to engage in a dialogue to explore, revise, eliminate or expand on these principles. 相似文献

Deficits in conceptual transfer on both implicit and explicit memory tests were obtained for memory-impaired temporal lobe epileptic (TLE) subjects in three studies. In Experiment 1, in which a generate-read paradigm was employed, memory-impaired TLEs failed to show normal generation effects on conceptually driven tests of semantic cued recall and general knowledge questions, although their data-driven memory as measured by word-fragment completion and graphemic cued recall tasks was normal. In Experiment 2, memory-impaired patients having left temporal lobe seizure foci were tested on these four tasks and compared with nonimpaired TLEs having right temporal foci. The left TLEs showed deficits on conceptually driven tasks and normal memory for data-driven tests. These findings were extended in Experiment 3, in which left TLE patients failed to show any benefit from blocked study, as compared with random study, on category production and semantic cued-recall tests, although right TLEs and normal controls showed blocking effects on both tasks. These findings may be accommodated by a processing framework of memory in which memory-impaired patients are characterized as having deficits in conceptual, but not in data-driven, processing capabilities. 相似文献

Data from rodent studies have indicated that stress experienced by pregnant mothers may result in behavioral and biological abnormalities in their offspring. However, few studies have examined the effects of prenatal stress on the offspring beyond the childhood period. In this study, 7 prenatally stressed (PNS) monkeys and 7 monkeys from undisturbed pregnancies were tested under mildly challenging conditions at 4 years of age. Following separation from cagemates and group formation, PNS monkeys showed more locomotion, abnormal and disturbance behavior than controls. Controls showed approximately six times more play than PNS animals. The PNS males showed the most clinging to others and the largest increase in contact with other animals over the period. Group differences were also found when the monkeys were observed as groups or alone in a playroom. Controls showed more explanatory behavior in the playroom, whereas PNS monkeys showed more inactivity. Control animals showed a decrease in distress vocalizations over time in the playroom, whereas PNS animals showed the opposite pattern. Control animals spent more time in proximity to and contact with cagemates than PNS animals. These results indicate that prenatal stress can have effects on adaptive and social behavior that persist into adolescence. 相似文献
