Gestalt psychology principles of figure‐ground segregation, symmetry, closure, proximity, good continuation, and similarity provide a simple yet powerful analytic vocabulary for discussing page layout and graphics. The six principles apply readily to typography, white space, data tables and maps, the relation between graphics and text, and other facets of textual design. The principles explain many difficulties that readers have in processing texts and graphics, and they explain why well‐designed pages and graphics are effective. 相似文献

Students in residential treatment center (RTC) schools are likely to have histories of extreme or ongoing relational trauma (e.g., abuse and neglect by primary caregivers), have substantial interpersonal and relationship problems, and exhibit many high-risk behaviors. Accordingly, these students may have particular difficulty forming positive relationships with teachers, yet student–teacher relationship quality in RTC schools has not been empirically studied. This study examines links between RTC school students' assessments of their relationships with teachers and their perceptions of self and others. Participants were 113 students in 2 RTC schools from 5th to 12th grade. Results indicate that male and female RTC students' positive perceptions (of self and others) are linked to positive assessments of their relationships with teachers. However, for girls in RTC schools, negative perceptions of self are linked to less positive assessments of the teacher–student relationship. Implications are discussed. 相似文献

This paper argues that learning outcomes need to be reclaimed from their current use as devices for monitoring and audit, and returned to their proper use in aiding good teaching and learning. We require a broader, flexible and more realistic understanding of learning outcomes, better suited to the realities of the classroom and of practical use to those teachers who wish to respond to the enthusiasm of their students. To this end, a new model is produced that starts from the idea of an articulated curriculum, and embraces both intended and emergent learning outcomes. The model employs the distinction between predicted and unpredicted learning outcomes, together with the distinction between those that are desirable and those that are undesirable. The resulting account is intended to aid understanding of the nature and proper use of learning outcomes in teaching and learning. 相似文献

Space has been of growing significance in social theory in recent years, yet, explorations of it in the scholarship of higher education have been limited. This is surprising, given the critical role space has in shaping staff and students' engagement with the university. Taking a practice-based approach and focusing on academic identities, this article analyses the spatial experience of an institution by defamiliarising spaces encountered in everyday work. We identify formative pressures upon institutional space, and how space then shapes experience: university spaces are designed for one purpose but come to be used for many, so that working within them can be a diverse and contradictory experience. The identification of academics with spaces is complex, and there are no simple experiences of belonging; rather, there is a constant project of identity-formation and change within mutable spaces. 相似文献

The methodology of protecting the European stained glass windows against environmental risk (e.g. meteorological factors, air pollution, microorganisms) by means of an external glazing is not new. In spite of many scientific studies carried out in the last 20 years, some questions were still up for discussion. The European VIDRIO (2002–2005) project gave an answer to these questions. The research carried out by the different project partners established a new multidisciplinary approach aimed at evaluating the efficiency of the protective glazing systems and their effects on stained glass windows conservation, and finally at assessing the most appropriate strategy to preserve stained glass windows. Scientific results showed that the so-called isothermal glazing (i.e. ventilation by the air coming from the inside of the building) protected efficiently the ancient stained glass window from environmental attack (i.e. rain, pollutants, condensation, thermal shocks) with very limited secondary effects. The scientific research highlighted that its efficiency was strongly related to the technical design of the protective system. In particular, the ventilation and the size of the interspace had to be carefully considered. The research developed within the VIDRIO project was turned into general recommendations to the owners and practitioners on the best practice for the stained glass windows future conservation. 相似文献

This paper deals with the leader-following consensus problem of multi-agent systems with the consideration that each agent can only transmit its position state to the neighbors at irregular discrete sampling times. In the proposed algorithm, a continuous-discrete time observer is designed for the continuous estimation of both position and velocity from the discrete position information of the neighbors. These estimated states are then used for designing a continuous control law which solves the leader-following consensus problem. Moreover, the dynamics of the leader is not fixed and can be controlled through an external input. The stability analysis has been carried out by employing the Lyapunov approach which provides sufficient conditions to tune the parameters according to the maximum allowable sampling period. The developed algorithm has been simulated and then tested on an actual multi-robot system consisting of three differential drive wheeled robots. Both simulation and hardware results validate the effectiveness of the control algorithm. 相似文献

We investigate in the context of crowdsourcing how seekers can increase open innovation performance, measured as received solver attention, by making two strategic decisions: selecting innovation tasks that are well suited for crowdsourcing and choosing between the potentials of status signalling through identity disclosure versus enjoying the benefits of anonymity. Drawing on uncertainty reduction theory, we suggest that a well-articulated problem statement reduces uncertainties of potential solvers and increases their willingness to participate. We argue that the ability of seekers to draft high-quality problem statements depends on the distance between the problem domain and their current knowledge stock. An analysis of 637 crowdsourcing projects finds that problem-seeker knowledge distance and received solver attention are curvilinear related such that moderate levels of knowledge distance maximize solver participation. However, high-status seekers who engage in identity-based status signalling are able to benefit from crowdsourcing across all levels of problem-seeker knowledge distance. 相似文献
