Objective
We examined (1) the prevalence of childhood sexual abuse (CSA) experiences as a function of cohort and gender, (2) the prevalence of factors associated with CSA as a function of cohort and whether the association of these factors with CSA remained the same irrespective of cohort, and (3) whether any cohort differences could be explainable by cohort differences in reporting bias.Method
We used the responses of 4,561 men (M = 29, SD = 7 years) and 8,361 female (M = 29, SD = 7 years) Finnish participants who responded to the Childhood Trauma Questionnaire-Short Form as well as questions regarding family structure.Results
The prevalence of CSA experiences varied between 0.7-4.6% for men and 1.8-7.5% for women depending on the item. Younger cohorts reported less CSA as well as less of the risk factors (physical neglect and abuse, emotional neglect and abuse, parental substances abuse, not growing up with both biological parents) that were positively associated with the likelihood of CSA. The effects of these risk factors did not vary as a function of the cohort. Also, the declining trend was not explainable by social desirability being higher in the younger cohorts.Conclusions
The results suggest that there is a real decline in the prevalence of CSA and it is associated with a simultaneous decline in factors associated with CSA. 相似文献92.

Despite extensive experience teaching residents, surgeons are an untapped resource for educating medical students. We hypothesized that by involving surgeons as teachers earlier in the medical school curriculum, medical students' interest in surgery will increase and their opinions of surgeons will improve. Five programs designed to involve surgeons as educators in the medical school curriculum were implemented. The first program, started in 2008, introduced surgical faculty into the first-year medical student anatomy dissection laboratories. Other programs initiated in 2008 included: Surgical Clinical Correlates in Anatomy, which involved faculty teaching through cadaver surgery; Clinical Pathologic Conferences in Anatomy, a surgeon-led conference based on clinical cases; and a women's faculty-student mentorship program. Table Rounds, a surgeon-led anatomy review that used clinical scenarios to quiz students was begun in 2009. All five programs were successfully integrated into the medical school curriculum. While student opinion of surgeons as educators improved, there were no significant changes in student interest in surgery as a career nor change in performance on written examinations over the Anatomy content covered by the surgeons. Surgical faculty and trainees can be integrated into the medical school curriculum. Involving surgeons as educators earlier in the medical school curriculum may have longer term effects than could be observed in this study. At a minimum, the experience improved student opinion of surgeons as educators. 相似文献

Movement patterns and physical strain during a novel, simulated cricket batting innings (BATEX) 总被引:1,自引:1,他引:0
A simulated cricket batting innings was developed to replicate the physical demands of scoring a century during One-Day International cricket. The simulated innings requires running-between-the-wickets across six 5-over stages, each of 21 min duration. To validate whether the simulated batting innings is reflective of One-Day International batting, movement patterns were collected using a global positioning system (GPS) and compared with previous research. In addition, indicators of physical strain were recorded (heart rate, jump heights, sweat loss, tympanic temperature). Nine club cricketers (mean ± s: age 20 ± 3 years; body mass 79.5 ± 7.9 kg) performed the simulated innings outdoors. There was a moderate trend for distance covered in the simulated innings to be less than that during One-Day batting (2171 ± 157 vs. 2476 ± 631 m · h?1; effect size = 0.78). This difference was largely explained by a strong trend for less distance covered walking in the simulated innings than in One-Day batting (1359 ± 157 vs. 1604 ± 438 m · h?1; effect size = 1.61). However, there was a marked trend for distance covered both striding and sprinting to be greater in the simulated innings than in One-Day batting (effect size > 1.2). Practically, the simulated batting innings may be used for match-realistic physical training and as a research protocol to assess the demands of prolonged, high-intensity cricket batting. 相似文献

Many studies investigating cue competition have focused on the blocking effect. We investigated the blocking effect with pigeons using a landmark-based spatial search task in both a touchscreen preparation (Exp. 1a) and an automated remote environmental navigation apparatus (Exp. 1b). In Phase 1, two landmarks (LMs: A and Z) appeared on separate trials as colored circles among a row of eight (touchscreen) or six (ARENA) identical response units. Subjects were rewarded for pecking at a target response unit to the right of LM A and to the left of an extraneous LM, Z. During the blocking trials in Phase 2, LM X was presented in compound with a second LM (A) that had been previously trained. On control trials, LM Y was presented in compound with LM B and a target in the same manner as in the trials of AX, except that neither landmark had previously been trained with the target. All subjects were then tested with separate trials of A, X, B, and Y. Testing revealed poor spatial control by X relative to A and Y. We report the first evidence for a spatial-blocking effect in pigeons and additional support for associative effects (e.g., blocking) occurring under similar conditions (e.g., training sessions, spatial relationships, etc.) in 3-D and 2-D search tasks. 相似文献

The annotation of texts in the school English classroom is central to the curriculum, examination and the history of English as a school subject. In this paper we explore ‘the way it is done’ across two different classrooms. We focus on the relationship between official definitions of annotation offered by national policies and examination syllabuses and its actualization in particular classrooms. The article takes a multimodal approach: attending to all modes of representation and communication in the teaching of English including image, gesture, gaze and the spatial organization of the classroom. 相似文献

A survey of over 2,000 craft makers in England and Wales undertaken in 2003 forms the basis of this study. It is compared with data from a previous national survey, enabling a unique longitudinal perspective on specific trends within this sector. The career paths travelled by makers between their initial training and forming their enterprises are explored and the dynamism of the sector and its potential contribution to the UK economy are made apparent. Three themes are addressed: the initial training of the makers; the emerging pattern of late entry to the sector; and, finally, individuals' career paths in the context of lifestyles and quality of life associated with working in the crafts. 相似文献
