Recent articles on the gifted self are characterized by theoretical confusion and lack of definitional clarity. This article, anchored in current self psychology theory, defines the self experience as the person's subjective experience of organization and meaning, the maintenance of which is crucial to normal functioning. Interactions with others are a formative part of the self experience. Traits of giftedness, and the reactions of others to these, contribute to the gifted self experience. Social and emotional problems of giftedness, such as those that arise with asynchronous development and perfectionism, are based on a compromised sense of cohesion and unity of the self experience.  相似文献

Previous attempts to examine the effects of different types of text format on reading have focused on the improvement of reading. The present study investigated the effect of using a text format that might be predicted to disrupt reading. In this study 56 individuals were presented with reading material presented in right-justified format and in'ragged'uneven line format. Subjects performed significantly worse on right-justified material. Subjects who were classified as good readers on the basis of a pretest were more affected than poor readers. It is suggested that this may result from differences in the reading style of good and poor readers.  相似文献

Persistent school shootings have generated ongoing pressure to assess and enhance crisis communication effectiveness via strategies such as resilience-building and post-crisis restoration. A network perspective offers a robust, multilevel approach for examining complex information flows among community, campus, and individual actors affected by crises. Drawing on relational and structural embeddedness and Uncertainty Management Theory, we offer nine propositions that help explain structural and relational changes in a network over time. Although theoretically driven, these propositions are primarily functional, offering practical implications for safety officials and administrators trying to understand, prepare for, and respond to crises. Thus, we suggest measures and recommendations to improve information flow, uncertainty management, and resilience before, during, and after a crisis.  相似文献

The problem of the construction of the optimal model of the automated control system of a Russian higher-education institution (the ACS of an RHEI) is studied. This term appeared in the 1970s–1980s and served as the beginning of a project that covered more than 50 of the largest higher-education institutions of the country and is also relevant today. Two main approaches to construction of an automated control system of Russian higher-education institutions are specified, viz., the development of a system using its own resources and the use of the product from a third-party developer. Examples of the application of these approaches are given and the structure of the elements (modules) of the systems is described. The necessity to search for the optimal structure of the elements included in the ACS of an RHEI is specified for most educational organizations taking their dimensions into account and their specific sectoral character, as well as the total expenditures for the acquisition (development) and support of the systems. An example of the structure of the optimal model and a third (combined) approach to its construction is given.  相似文献
