资本主义生态问题的解决：资本主义和社会主义条件下的可能性

作者在本文中区分了3个为实现社会可持续发展而必须加以解决的资本主义生态问题：增长、技术和消费。与其之前的著作相一致,特别是在马克思主义生态传统方面,作者认为增长问题的解决需要对资本主义制度进行替代。而这是必要而非充分条件：生态可持续性同样有赖于对技术和消费问题的解决,这要求不间断地进行改革。然而,在资本主义制度下这种改革的力度相对较小。历史资料证明,不能保证作为资本主义制度替代物的社会主义一定能够实现生态可持续。社会主义制度要实现生态可持续,必须满足两个条件：一是对资本主义增长方式的革命性突破,二是对技术和消费的不间断改革。苏联和古巴的例子能够证明上述观点。     

会飞的书箱

<正>一“植股山、明长城、烽火台都没变,只是……啥时候种了这么多桑葚树。”李国庆带着小孙子洋洋,站在山脚下的农家院里,看着漫山遍野的桑葚树感慨道。就连农家院的院子里,也都种上了桑葚树。高大的桑葚树遮天蔽日,枝叶伸出了墙头,树上挂满了青红紫色的桑葚果。     

Epidemiology of insertional and midportion Achilles tendinopathy in runners:A prospective cohort study

Background:Achilles tendinopathy(AT) is a common problem among runners.There is only limited evidence for risk factors for AT,and most studies have not defined the AT subcategories.No study has compared the incidence and risk factors between insertional AT and midportion AT,though they are considered distinct.This study aimed to assess incidence and risk factors of AT based on data from a large prospective cohort.The secondary aim was to explore differences in risk factors between insertional an...     

DNA microarray wet lab simulation brings genomics into the high school curriculum

We have developed a wet lab DNA microarray simulation as part of a complete DNA microarray module for high school students. The wet lab simulation has been field tested with high school students in Illinois and Maryland as well as in workshops with high school teachers from across the nation. Instead of using DNA, our simulation is based on pH indicators, which offer many ideal teaching characteristics. The simulation requires no specialized equipment, is very inexpensive, is very reliable, and takes very little preparation time. Student and teacher assessment data indicate the simulation is popular with both groups, and students show significant learning gains. We include many resources with this publication, including all prelab introductory materials (e.g., a paper microarray activity), the student handouts, teachers notes, and pre- and postassessment tools. We did not test the simulation on other student populations, but based on teacher feedback, the simulation also may fit well in community college and in introductory and nonmajors' college biology curricula.     

体力活动与癌症生存研究的10大问题

摘要：今天的美国有1 400万的癌症存活者,其中的很多存活者中都接受了多种治疗,包括手术、放疗、化疗、靶向治疗等。这些治疗能够延长生存时间,但同时也会带来很多急慢性的副作用,危害健康,影响生活质量。体力活动（PA）与癌症生存这一领域发展迅速,主要研究PA对癌症患者的影响。基于该领域的研究进展,提出了以下10大研究问题：1）PA能够降低癌症复发风险、和/或提高存活吗？2）PA能够影响癌症治疗决策、完成率、和/或患者对治疗的反应吗？3）癌症存活者的最佳运动处方是什么？4）静坐少动行为对癌症存活者有何影响？5）癌症存活者最有效的体力活动干预方案是什么？6）哪些癌症会影响病人对PA的反应？7）癌症存活者进行体力活动时需要注意的安全问题有哪些？8）哪些具体的癌症症状可以由PA解决？9）对于癌症晚期患者,体力活动还有何作用？10）如何将体力活动研究结果转化到临床和社区肿瘤实践中来？上述问题的回答至关重要,这不仅关系到体力活动和癌症存活这一研究领域的发展,更重要的是,能够为每年数百万新诊断为癌症的病人、正在接受癌症治疗的病人、治疗结束处于恢复中的病人或是那些正在与晚期癌症抗争的病人带来福音。

迷上练习场

在许多职业赛事上,你不用破费很多就可以大有所获。乔·狄克逊的下巴紧紧贴在球场的钢丝网上,场内的罗杰·费德勒现在离她只有不到5码远。这位她最喜爱的网球选手,在她的注视下练习完上旋发球后,接着开始练习正手抽击。这是一记典型的费德勒式正拍,球"嗖"地飞出,刚刚过网,狠狠地砸在了边线上。狄克逊情不自禁地吹了个口哨,费德勒轻     

The second leg home advantage: evidence from European football cup competitions

The home advantage is a widely acknowledged sporting phenomenon, especially in association football. Here, we examine the second leg home advantage, an effect that is discussed in the public domain but which has received very little scientific attention. The second leg home advantage effect occurs when on average teams are more likely to win a two-stage knock-out competition when they play at home in the second leg. That is, both teams have a home advantage but this advantage is significantly greater for the team that plays at home second. Examining data from three different European Cup football competitions spanning 51 years, we show that the second leg home advantage is a real phenomenon. The second leg home team has more than a 50% probability to qualify for the next round in the competition even after controlling for extra time and team ability as possible alternative explanations. The second leg home advantage appears, however, to have decreased significantly over the past decade. Possible reasons for its existence and subsequent decline are presented.
