Radiological images show anatomical structures in multiple planes and may be effective for teaching anatomical spatial relationships, something that students often find difficult to master. This study tests the hypotheses that (1) the use of cadaveric computed tomography (CT) scans in the anatomy laboratory is positively associated with performance in the gross anatomy course and (2) dissection of the CT‐scanned cadaver is positively associated with performance on this course. One hundred and seventy‐nine first‐year medical students enrolled in gross anatomy at Boston University School of Medicine were provided with CT scans of four cadavers, and students were given the opportunity to choose whether or not to use these images. The hypotheses were tested using logistic regression analysis adjusting for student demographic characteristics. Students who used the CT scans were more likely to score greater than 90% as an average practical examination score (odds ratio OR 3.6; 95% CI 1.4, 9.2), final course grade (OR 2.6; 95% CI 1.01, 6.8), and on spatial anatomy examination questions (OR 2.4; 95% CI 1.03, 5.6) than were students who did not use the CT scans. There were no differences in performance between students who dissected the scanned cadavers and those who dissected a different cadaver. These results demonstrate that the use of CT scans in medical gross anatomy is predictive of performance in the course and on questions requiring knowledge of anatomical spatial relationships, but it is not necessary to scan the actual cadaver dissected by each student.

The study examined relations between intelligence and academic achievement scores at different levels of socio-economic status and refined family environment measures for English children from three different age cohorts. Data were collected as part of a national survey of 11-, 12-, and 15-year-old schoolchildren. Regression surfaces were constructed from models which examined possible linear, interaction, and curvilinear relations between the variables. The Jackknife technique was used to adjust the significance levels in the investigation. At each environment level, increments in intelligence test scores are associated with increases in academic achievement, while there are differential gender relations between the measures of family environment and achievement at different levels of intellectual ability. 相似文献

OBJECTIVE: The purpose was to identify different operational definitions of maltreatment severity, and then to examine their predictive validity. METHOD: Children and their primary caregivers participating in a consortium of ongoing longitudinal studies were interviewed when they were approximately 4 and 8 years of age to assess behavior problems, and developmental and psychological functioning. Four different severity definitions were identified and applied to 519 children who were reported for alleged maltreatment between Birth and the Age 8 interview. A taxonomy for defining maltreatment characteristics (Barnett, Manly, & Cicchetti, 1993) was applied to Child Protective Service records to define severity as (a) Maximum Severity within each of five maltreatment types, (b) Overall Maximum Severity across the five types, (c) Total Severity or the sum of the maximum severity for each of five types, and (d) Mean Severity or the average severity for those types of maltreatment alleged, during each of two time periods-Birth to Age 4, and Age 4 to Age 8. RESULTS: Regression analyses that controlled for socio-demographic factors, early maltreatment (Birth to Age 4), prior functioning (Age 4), and site revealed that (a) all four severity definitions for maltreatment reports between Age 4 and Age 8 predicted Age 8 behavior problems, (b) Maximum Severity by Type and Mean Severity predicted adaptive functioning at Age 8, and (c) only Maximum Severity by Type was related to anger, at Age 8. Follow-up regression analyses indicated that only Maximum Severity by Type, specifically physical abuse, accounted for outcomes, beyond maltreatment occurrence versus non-occurrence. CONCLUSION: The results suggest that maltreatment severity definitions that preserve ratings within types of maltreatment may be the optimal approach to measure the severity of children's experiences. 相似文献

Community colleges historically have demonstrated an ability and desire to address needs unmet by other sectors of postsecondary education. On the assumption that productivity assessment should be molded to reflect the unique missions and approaches of 2‐year institutions, this study examined preferences for broadly stated institutional goal areas as well as for productivity measures for assessing the achievement of these goals. Findings regarding the goal areas substantiate the unique community college mission and reveal preferences for measures that reflect consistent satisfaction or areas which can be impacted directly by community college trustees, administrators and faculty. The study was conducted over an 8‐month period in 45 institutions, 10 of which were community colleges. 相似文献

Fluid and electrolyte balance in elite male football (soccer) players training in a cool environment
There are few data in the published literature on sweat loss and drinking behaviour in athletes training in a cool environment. Sweat loss and fluid intake were measured in 17 first-team members of an elite soccer team training for 90 min in a cool (5°C, 81% relative humidity) environment. Sweat loss was assessed from the change in body mass after correction for the volume of fluid consumed. Sweat electrolyte content was measured from absorbent patches applied at four skin sites. Mean (?± s) sweat loss during training was 1.69?±?0.45 l (range 1.06?-?2.65 l). Mean fluid intake during training was 423?±?215 ml (44?-?951 ml). There was no apparent relationship between the amount of sweat lost and the volume of fluid consumed during training (r 2 = 0.013, P = 0.665). Mean sweat sodium concentration was 42.5?±?13.0 mmol?·?l?1 and mean sweat potassium concentration was 4.2?±?1.0 mmol?·?l?1. Total salt (NaCl) loss during training was 4.3?±?1.8 g. The sweat loss data are similar to those recorded in elite players undergoing a similar training session in warm environments, but the volume of fluid ingested is less. 相似文献
