The inculcation of academic integrity among post-graduate students is an ongoing concern for universities across the world. While various researchers have focused on causal relations between forms of instruction, student characteristics, and possession of academic integrity, there is need for an increased examination of the role of supervisors in shaping student perceptions of academic integrity. Unlike the undergraduate level, where student interaction with professors is often limited, post-graduate students have an ongoing relationship with their supervisors, whether at the Masters or Doctorate level. In some ways like masters over apprentices, rather than teachers over students, supervisors engage in continued interaction with post-graduate students, shaping these students views not only on the substance of their research, but also in how researchers “should” act. As part of a larger project in examining post-graduate student opinions on academic integrity and research ethics, we conducted surveys to investigate the relationship between student perceptions of their supervisors and student perceptions of academic integrity. We use survey data from a population of post-graduate students at a comprehensive research university in Hong Kong to analyze student perceptions of academic integrity and how students might be influenced by their supervisors’ service as mentors and/or ethic exemplars. 相似文献

Although decades of research provide consistent evidence supporting the perspective that the self is divided into social and personal components each with unique and predictable motivational associations, the current paper argues that something important has been overlooked. Specifically, what has been lost is the acknowledgment that although different components of self can be activated, and can have important implications, the two aspects of self are highly interconnected. Specifically in this paper, it is argued that (i) the independent self is affected by social motivations and (ii) the social self is affected by independent motivations. Two studies are presented in support of these hypotheses. We conclude by comparing our perspective with existing theories of the self and by discussing implications for the study of the self. 相似文献

A novel modular connectionist architecture is presented in which the networks composing the architecture compete to learn the training patterns. An outcome of the competition is that different networks learn different training patterns and, thus, learn to compute different functions. The architecture performs task decomposition in the sense that it learns to partition a task into two or more functionally independent tasks and allocates distinct networks to learn each task. In addition, the architecture tends to allocate to each task the network whose topology is most appropriate to that task. The architecture's performance on “what” and “where” vision tasks is presented and compared with the performance of two multilayer networks. Finally, it is noted that function decomposition is an underconstrained problem, and, thus, different modular architectures may decompose a function in different ways. A desirable decomposition can be achieved if the architecture is suitably restricted in the types of functions that it can compute. Finding appropriate restrictions is possible through the application of domain knowledge. A strength of the modular architecture is that its structure is well suited for incorporating domain knowledge. 相似文献

Two main questions were addressed in the present study. First, does the existence of kinematic regularities in the extrinsic space represent a general rule? Second, can the existence of extrinsic regularities be related to specific experimental situations implying, for instance, the generation of compliant motion (i.e. a motion constrained by external contact)? To address these two questions we studied the spatio-temporal characteristics of unconstrained and compliant movements. Five major differences were observed between these two types of movement: (1) the movement latency and movement duration were significantly longer in the compliant than in the unconstrained condition; (2) whereas the hand path was curved and variable according to movement direction for the unconstrained movements, it was straight and invariant for the compliant movements; (3) whereas the movement end-point distribution was roughly circular for the unconstrained movements, it was consistently elongated and typically oriented in the movement direction for the compliant movements; (4) whereas constant errors varied as a function of target eccentricity for the unconstrained movements, they were independent of this factor for the compliant movements; (5) the instruction to move the final effector along a straight line path influenced the characteristics of the unconstrained movements but not the characteristics of the compliant movements. When considered together, the previous observations suggest that compliant and unconstrained movements involve different planning strategies. Our data support the hypothesis that unconstrained motions, unlike compliant motions, are not programmed to follow a straight line path in the extrinsic space. This observation provides a theoretical frame of reference within which some apparently contradictory results reported in the movement generation literature may be explained. 相似文献
