As more interpersonal interactions move online, people increasingly get to know and recognize one another by their self-selected identifiers called usernames. Early research predicted that the lack of available cues in text based computer-mediated communication (CMC) would make primitive categories such as biological sex irrelevant in online interactions. Little is known about the types of perceptions people make about one another based on this information, but some limited research has shown that questions about gender are the first to be asked in online interactions and sex categorization has maintained salience. The current project was designed to examine the extent to which individuals might include obvious gender information in their usernames, as well as how easily gender could be attributed from usernames. Seventy-five coders were asked whether or not they could assign 298 people to a sex category based only on their username, and then to rate how confident they were in making the attribution. Results indicated that coders were fairly inaccurate in making these attributions, but moderately confident. Additionally, the results indicated that neither women nor men were more accurate in attributing gender from usernames, and that neither women nor men tended to use more obvious gender markers in their usernames. Additionally, those who did use obvious gender markers in their username tended to have less experience with computer chat. The results are discussed in conjunction with the limitations of the present investigation, and possibilities for future research. 相似文献

Awareness is a personal experience, which is only accessible to the rest of world through interpretation. We set out to identify a neural correlate of visual awareness, using brief subliminal and supraliminal verbal stimuli while measuring cerebral blood flow distribution with H(2)(15)O PET. Awareness of visual verbal stimuli differentially activated medial parietal association cortex (precuneus), which is a polymodal sensory cortex, and dorsolateral prefrontal cortex, which is thought to be primarily executive. Our results suggest participation of these higher order perceptual and executive cortical structures in visual verbal awareness. 相似文献

Since the burnout syndrome has a negative impact both on the individual affected and the institution in which he/she is employed, it is important to identify the factors which may alleviate the level of burnout. Social support is said to be one of such factors. Our study was undertaken to investigate the influence of social support in the workplace and general social support on relationships between global stress and stress related to role conflict, ambiguity, and overload and burnout components (emotional exhaustion, depersonalization, and personal accomplishment). The subjects were 1,023 hospital nurses. The results indicate that burnout level correlates highly with organizational and global stress. The role of social support in determining the level of particular burnout components varied according to the type and scope of support. No reliable correlation was found between emotional exhaustion and social support of any type. The level of depersonalization was related only to general support whereas a personal accomplishment factor was related to both types of support. The study did not reveal a buffering effect of both types of social support on the relationships between stress and components of burnout. 相似文献

Our purpose is to formulate a complete logic of propositions that takes into account the fact that propositions are both senses provided with truth values and contents of conceptual thoughts. In our formalization, propositions are more complex entities than simple functions from possible worlds into truth values. They have a structure of constituents (a content) in addition to truth conditions. The formalization is adequate for the purposes of the logic of speech acts. It imposes a stronger criterion of propositional identity than strict equivalence. Two propositions P and Q are identical if and only if, for any illocutionary force F, it is not possible to perform with success a speech act of the form F(P) without also performing with success a speech act of the form F(Q). Unlike hyperintensional logic, our logic of propositions is compatible with the classical Boolean laws of propositional identity such as the symmetry and the associativity of conjunction and the reduction of double negation.Presented byJan Zygmunt 相似文献

The decision to hospitalize a psychiatric patient is often a source of controversy. This fact is reflected in the Connecticut Mental Health Center’s program of quality assessment. The center conducts individual, retrospective chart review using a 32-page checklist of normative criteria. The primary purpose of this portion of the chart review system is to highlight those cases in which a patient may have been hospitalized unnecessarily. We present and analyze the cumulative data from 300 cases for which the criteria-for-hospitalization scale was completed. We conclude that the scale is an efficient instrument and is convenient for justifying hospitalization. We suggest minor revisions in the scale and speculate upon its as-yet-untapped research potential. 相似文献
