In the present study, we tested a computer-based procedure for assessing very concise summaries (50 words long) of two types of text (narrative and expository) using latent semantic analysis (LSA) in comparison with the judgments of four human experts. LSA was used to estimate semantic similarity using six different methods: four holistic (summary-text, summary-summaries, summary-expert summaries, and pregraded-ungraded summary) and two componential (summary-sentence text and summary-main sentence text). A total of 390 Spanish middle and high school students (14–16 years old) and six experts read a narrative or expository text and later summarized it. The results support the viability of developing a computerized assessment tool using human judgments and LSA, although the correlation between human judgments and LSA was higher in the narrative text than in the expository, and LSA correlated more with human content ratings than with human coherence ratings. Finally, the holistic methods were found to be more reliable than the componential methods analyzed in this study.  相似文献

The validity of rating of perceived exertion (RPE) in predicting lactate threshold during an incremental test was analyzed in 15 men with type 2 diabetes (M age = 53.4 yr., SD = 12.9). Blood glucose, lactate, and minute ventilation (VE)/VO2 responses identified the lactate, ventilatory, and glucose thresholds. Workloads (W) corresponding to RPEs 12, 13, 14, and 15 were determined. Second-order polynomials fit to VE/W and [lac]/W ratios corresponding to RPEs of 9-10, 12-13, and 16-17 also identified workloads above which there was an overproportional increase in VE and [lac]. These workload breakpoints did not differ, although at RPE 12 underestimated and at RPE 15 overestimated lactate threshold. RPE 13 and 14 and the responses of VE/W and [lac]/W to submaximal exercise accurately predicted lactate threshold.  相似文献

Likert-type self-report scales are frequently used in large-scale educational assessment of social-emotional skills. Self-report scales rely on the assumption that their items elicit information only about the trait they are supposed to measure. However, different response biases may threaten this assumption. Specifically, in children, the response style of acquiescence is an important source of systematic error. Balanced scales, including an equal number of positively and negatively keyed items, have been proposed as a solution to control for acquiescence, but the reasons why this design feature worked from the perspective of modern psychometric models have been underexplored. Three methods for controlling for acquiescence are compared: classical method by partialling out the mean; an item response theory method to measure differential person functioning (DPF); and multidimensional item response theory (MIRT) with random intercept. Comparative analyses are conducted on simulated ratings and on self-ratings provided by 40,649 students (aged 11–18) on a fully balanced 30-item scale assessing conscientious self-management. Acquiescence bias was explained as DPF and it was demonstrated that: the acquiescence index is highly related to DPF; balanced scales produce scores controlled for DPF; and MIRT factor scores are highly related to scores controlled for DPF and the random intercept is highly related to DPF.  相似文献

The aim of this study is to investigate which coping strategies can predict success or failure in the Brazilian Army’s Jungle Operations Course. To achieve this, the sample included 36 military volunteers (18 who quit and 18 who completed the course) from a total of 63 candidates (57.14%), all male career officers and sergeants of the Brazilian Army. Results indicate that completers (n = 18) show significantly higher scores in 2 of the 8 different coping strategy factors—self-control and positive reappraisal—than those in the quitters group (n = 18). In general, emotion-focused strategies were prominent in relation to problem-focused ones. The findings of this study suggest that coping strategies focused on emotion, especially self-control and positive reappraisal, can influence individuals’ performance in situations of intensive military training, which possibly makes them more resilient, preparing them for a more successful training.  相似文献

The present study tackles two overlooked aspects of analogical retrieval: (a) whether argumentation activities elicit a spontaneous search for analogical sources, and (b) whether strategic search can relax the superficial bias typically obtained in experimental studies of analogical retrieval. In Experiment 1, participants had to generate arguments for a target situation under three conditions: without indication to use analogies, with indication to use analogies, and with indication to search for sources within domains provided by the experimenters. Results showed that while voluntary search yields analogical retrievals reliably, the argumentation activity seldom elicits spontaneous remindings. A second set of results demonstrated that the superficial bias can be strategically relaxed, leading to a majority of distant retrievals. Experiment 2 replicated this result with the instruction to search within domains different from that of the target, and without providing a list of specific domains. The theoretical and educational implications of these findings are discussed.  相似文献

Public schools are an ideal setting for the delivery of mental health services to children. Unfortunately, services provided in schools, and more so in urban schools, have been found to lead to little or no significant clinical improvements. Studies with urban school children seldom report on the effects of clinician training on treatment fidelity and child outcomes. This study examines the differential effects of two levels of school-based counselor training: training workshop with basic consultation (C) vs. training workshop plus enhanced consultation (C +) on treatment fidelity and child outcomes. Fourteen school staff members (counselors) were randomly assigned to C or C +. Counselors implemented a group cognitive behavioral therapy protocol (Coping Power Program, CPP) for children with or at risk for externalizing behavior disorders. Independent coders coded each CPP session for content and process fidelity. Changes in outcomes from pre to post were assessed via a parent psychiatric interview and interviewer-rated severity of illness and global impairment. Counselors in C + delivered CPP with significantly higher levels of content and process fidelity compared to counselors in C. Both C and C + resulted in significant improvement in interviewer-rated impairment; the conditions did not differ from each other with regard to impairment. Groups did not differ with regard to pre- to- posttreatment changes in diagnostic severity level. School-based behavioral health staff in urban schools are able to implement interventions with fidelity and clinical effectiveness when provided with ongoing consultation. Enhanced consultation resulted in higher fidelity. Enhanced consultation did not result in better student outcomes compared to basic consultation. Implications for resource allocation decisions with staff training in EBP are discussed.  相似文献

The identification of patients at risk for breast cancer by genetic testing has proven to reduce breast cancer mortality. In 2010, due to a lack of systematization in hereditary cancer assistance in our center, we implemented a multidisciplinary Heredofamilial Cancer Unit (HFCU). We analyze if the HFCU improved the rates of referrals and preventive management of breast cancer patients with genetic risk. We retrospectively compared family history records, referrals of high-risk patients to genetic counseling, and detection and management of patients with BRCA1/2 mutations in two cohorts of breast cancer patients diagnosed before (first period: 2007–2010) and after the creation of the HFCU (second period: 2010–2013). In the first period, 893 patients were included, and 902 were included in the second. Due to the inability to establish their genetic risk, 142 patients (15.9%) vs. 70 (7.8%) were excluded from analysis (p?<?0.001). Among the evaluable patients, 194 (25.8%) vs. 223 (26.8%) fulfilled one or more risk criteria (p?=?0.65). Family history documentation in patient’s medical records (92.4 vs. 97.8%, p?<?0.001) and referral rate (26.3 vs. 52%, p?<?0.0001) significantly increased in the second period. Eight BRCA1/2 mutations were detected among patients referred in the first period and 17 among those referred to the HFCU. The rate of preventive surgeries in patients with BRCA mutations significantly increased in the second period (25 vs. 76.5%, p?=?0.03). In conclusion, there was a clear improvement in family history records, referrals, and preventive surgeries in breast cancer patients with genetic risk after the implementation of the HFCU.  相似文献
