Single-crystal (0 0 0 1) GaN samples have been deformed with a Vickers indenter at room temperature using loads in the range from 0.02 to 4.90 N. Dislocations and cracks at the indentations were examined by means of scanning electron microscopy, cathodoluminescence, light microscopy and transmission electron microscopy. Geometrical relations could be found between the dislocation arrangement, cracks and the orientation of the indenter. The orientation of the indenter has only a slight effect on the dislocation pattern, but the crack system is predominantly determined by the symmetry and the orientation of the indenter. 相似文献

Abstract Goal orientation is an action style implying the development of long-range and precise goals, and persistent pursuit of these goals. Goal orientation is not only important for a person's own performance but also for the performance of others in a co-operative work setting. This applies particularly to team leaders, whose goal orientation was predicted to correlate with both team performance and quality of group interaction within the team. In a sample of 44 team leaders and 141 other team members of software development projects it was found that team leaders' goal orientation is related to the quality of the development process, the quality of the final product, and the interaction within the team. This is true both for team leaders' estimates of the dependent variables and for aggregated scores of the team members' estimates. Interaction effects between team members' and team leaders' goal orientation were also found. 相似文献

A study of 21 software development (SD) project groups using data from 170 participants holding different positions (engineers, user representatives, project managers) and a quasi-longitudinal design shows that user participation inhibits, and standardization of methods and tools facilitates, effective SD project performance. Over and above these effects, hierarchical regression analysis reveals taskrelated internal communication to predict performance positively. Moderated regression analysis reveals that high communication facilitates project performance more strongly in late stages of the project life-cycle and when standardization of methods and tools is low. Implications for facilitating SD projects' functioning, for future research and theory building, are discussed. 相似文献

Backward inhibitory learning in honeybees: a behavioral analysis of reinforcement processing 下载免费PDF全文
One class of theoretical accounts of associative learning suggests that reinforcers are processed according to learning rules that minimize the predictive error between the expected strength of future reinforcement and its actual strength. The omission of reinforcement in a situation where it is expected leads to inhibitory learning of stimuli indicative for such a violation of the prediction. There are, however, results indicating that inhibitory learning can also be induced by other mechanisms. Here, we present data from olfactory reward conditioning in honeybees that show that (1) one- and multiple-trial backward conditioning results in conditioned inhibition (CI); (2) the inhibition is maximal for a 15-sec interval between US and CS; (3) there is a nonmonotonic dependency on the degree of CI from the US-CS interval during backward pairing; and (4) the prior association of context stimuli with reinforcement is not necessary for the development of CI. These results cannot be explained by models that only minimize a prediction error. Rather, they are consistent with models of associative learning that, in addition, assume that learning depends on the temporal overlap of a CS with two processes, a fast excitatory and a slow inhibitory one, both evoked by a reinforcer. The fmdings from this behavioral analysis of reinforcement processing are compared with the known properties of an individual, identified neuron involved in reinforcement processing in the bee brain, to further understand the mechanisms underlying predictive reward learning. 相似文献

Conclusion In summary, then, what is conducive to creative functioning is arelaxation of one's rationality: the analyst who feels exhilarated rather than threatened, receptive rather than anxious, at the hint of an appearance of the unexpected, at the peeking out of something that may challenge his understanding, that may not fit the theory neatly—he is the one who is capable of more creativity. The analyst might thus orient himself to give rein to his own inner processes, his inner radar rather than his intellect, and thus without preconceived theoretical expectations aspire to discover anew that which is uncovered ineach patient. It is this which makes each analysis a fresh experience, not a stale rehash, for the therapist; it is this which makes the analysis an authentic encounter for the patient—thus, an adventuring together.Another factor grows out of the above. If the analyst orients himself to think-feel-respondvia that deeper more personal channel of images — closer to the language of dream images early in the history of analysis recognized as the royal road to the unconscious—then he may find his creative responsiveness more liberated, his intuition in general more active for the work of the session. He thereby may enliven his reactivity not only along the pithy, affect-enriched modality of images, but also along other dimensions of intervention involving more nuanced responses of all sorts.Read at the convention of the Metropolitan Academy of Psychoanalytic Training, March 12, 1971, New York City, panel on The Creative Process. 相似文献

Kant's ethics is used by some as a defence of the exploitation of animals and is criticised by others for not recognising any moral relevance of the plight of animals. These appeals overlook the broad applicability of Kant's principles. In this article, I argue that Kant's ethics implies a duty to abstain from most meat and some other animal products derived from farming. I argue that there is a Kantian principle not to choose goods that have been derived from wrongdoing, with certain qualifications. This principle isolates the wrong of using others to commit wrongdoing on one's behalf. As has been argued by others, Kant's ethics implies that animal farming as we know it in our society almost universally involves wrongdoing and the slaughter of animals is especially tied to wrongdoing. I argue for a broad sense in which these ideas together imply that choosing farmed meat, and probably other animal products, is treating animal industry workers as mere means. Thus, we have a Kantian duty to abstain from these products. 相似文献

The present research investigates how young children evaluate and reason about the disclosure of private information. Using story vignettes, children aged 4–5 and 7–8 years were asked to evaluate an individual who passed on information from a peer revealing that he or she had broken a rule (e.g., stolen a cookie; rule type) or lacked a skill (e.g., could not ride a bicycle; competence type). These negative valence stories were compared with positive valence stories in which the peer had followed a rule or possessed a skill. Younger children approved the sharing of positive, but not negative, information, irrespective of type (rule vs. competence). Older children disapproved the disclosure of someone's incompetence, whereas they approved the disclosure of a rule violation. Children justified their evaluations by reference to social rules in the rule‐type vignettes and to an individual's feelings in the competence‐type vignettes. The findings suggest that young children are concerned about the disclosure of negative information about other people, but with age they become increasingly concerned about protecting the social order even at the cost of individual privacy. 相似文献

Faking has remained a major concern for organizations using self‐report personality measures for selection. Scholars recenlty developed a new middle‐warning faking‐mitigation procedure. The present replication study was the first field test in the United States using 193 applicants for an entry‐level position in a New York‐based consulting firm. Results replicated most of Fan et al.'s findings including (a) the middle‐warning significantly lowered fakers' personality scores over retesting, whereas the control message had little influence on nonfakers; (b) the above warning effect carried over to personality scales that were not retested; and (c) the persistent tendency of potential fakers rising to the top of personality score distribution was weakened. In addition, applicants' perceptions were not being negatively affected by the warning. 相似文献
