Search strategies in syntactic reanalysis.

We first consider the nature of syntactic reanalysis, paying particular attention to questions about whether and how it differs from the construction of an initial analysis, such as whether it is encapsulated or whether alternatives are considered in parallel or not. We then outline different strategies that the processor may use in reanalysis, and review the relevant evidence. We show that our experimental evidence is compatible with an encapsulated serial search strategy.

Developing and evaluating an emergency nursing orientation pathway.

OBJECTIVE: Orientee evaluation forms frequently focus on tasks and technical skills rather than decision-making skills. An orientation pathway was developed to evaluate orientee clinical decision-making skills. The pathway can assist in identifying orientees who require additional educational resources or interventions. Early interventions may decrease the length of orientation, increase an employee's length of stay in the institution, and contribute to cost savings. METHODS: The pathway was developed with employee exit interview data, preceptor interviews, identification of critical indicators, and the orientation literature. The pathway consists of six categories. Indicators within each category were identified and ranked according to four levels of proficiency (level 1 for the least proficient and level 4 for the most proficient). A convenience sample of seven ED orientee and preceptor pairs agreed to participate in the pilot use of the pathway. An expected timeline of progress had been developed by a group of 20 preceptors during a preceptor workshop. An average proficiency level (score) was obtained for each category for 12 weeks with the weekly scores plotted on the pathway. This level was compared with the expected proficiency level in each category for each week. Demographic information was obtained from the orientee and preceptor pairs to determine whether certain characteristics facilitate pathway progression. Data were analyzed with frequency distributions, and measures of central tendency and variance. Spearman's rank correlations were used to examine the proficiency level in each category for each week in relation to demographic characteristics of the preceptor and orientee. RESULTS: Orientees progressed faster than expected in all categories. It took 8 weeks for an orientee to attain the highest proficiency level in all categories. The fastest progress was made in the category " Accurately Evaluates Patient Responses." Slowest progress was made in the category "Safety in Blood and Drug Administration." Preceptors and orientees rated in the pathway as very useful. DISCUSSION: Further studies with the orientation pathway may help to determine the ideal time frame for orientation, characteristics of orientees who progress as expected or faster, and educational strategies to facilitate orientee progression and clinical decision making.

Stress incubation and the onset of affective disorders.

Incubation is the process by which life events influence the onset of psychiatric disorder after an appreciable delay. It has long been recognised clinically. In this paper we use data from the Camberwell Collaborative Depression Study to see whether incubation effects can be demonstrated in depressive illness. We used a novel adaptation of survival analysis for this purpose. The results suggest that incubation does occur in depressive disorder, that it is much less important than the effect of life events close to onset, that it is apparent in women but not in men, and that it is no more evident preceding endogenous than neurotic symptom patterns.
