气候的未来

地球得以成功地保持使生命能够在其表面生存的适度高温,是由于有各种各样的因素防止了从太阳射线获得的热量完全反射出去的缘故。但至今我们还不了解,近十年来对地球有影响的气候变化(有些变化具有严重的经济后果)是否是气候发生大变迁的信号,或者仅仅是围绕平均状态的变动。只要考察到大气中二氧化碳浓度上升这一新因素,我们就可以找到问題的答案。对CO_2的研究联系着好几门学科(物理学、化学以及生物学)。这表明这一研究所使用的方法既复杂而又丰富。     

Comparative orotomy of the Archean Superior and Phanerozoic Altaid orogenic systems

We compare and contrast the materials and mechanisms of continental crustal growth in the largest preserved regions of Phanerozoic and Archean juvenile additions to the crust,to test for similarities or differences in the formation of continents through time.We accomplish this through a comparison of map patterns,lithological contents,and structural and metamorphic evolution of the Phanerozoic Altaid orogenic system of Asia,with the Archean Superior Province of the North American Craton,using a ...     

Learning surgically oriented anatomy in a student-run extracurricular club: an education through recreation initiative

Didactic and laboratory anatomical education have seen significant reductions in the medical school curriculum due, in part, to the current shift from basic science to more clinically based teaching in North American medical schools. In order to increase medical student exposure to anatomy, with clinical applicability, a student-run initiative called surgically oriented anatomy prosectors (SOAP) club was created within the extracurricular program at the Schulich School of Medicine and Dentistry, The University of Western Ontario, London, Canada. SOAP invites surgeons and residents from various surgical specialties to demonstrate, on a cadaver, a surgical procedure of their choosing. During the demonstration, the anatomy, as it relates to the surgical procedure, is discussed. The students then break into smaller groups to examine the relevant anatomy on the cadavers, during which time the discussion is broadened. The group continues the conversation in a social environment with refreshments. SOAP is one of the most popular extracurricular clubs with 65% of first and second year medical students registered as members. The high demand for SOAP, along with the positive participant feedback, may be due to its utilization of the principle of education through recreation, which seeks to provide opportunities for learning seamlessly throughout all facets of life. It also demonstrates the desire, amongst certain medical students, to learn applied anatomy, particularly within a surgical context.

Changes in the prevalence of child sexual abuse, its risk factors, and their associations as a function of age cohort in a Finnish population sample

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.

更新奥林匹克教育

“奥林匹克教育”是个老话题,对此首先要明确关于奥林匹克教育的两种不同涵义:1.奥林匹克教育是关于奥运会和奥林匹克历史的教育。2.奥林匹克教育是通过奥运会进而服务于奥林匹克运动更广泛的人文、社会和文化的教育。在此次论坛上,我会向大家诠释一个既令人理解但又非常令人遗
