Science Letters：Application of new tissue microarrayer-ZM-1 without recipient paraffin block

The ZM-1 tissue microarrayer designed by our groups is manufactured in stainless steel and brass and contains many features that make TMA （tissue microarray） paraffin blocks construction faster and more convenient. By means of ZM-1 tissue microarrayer, biopsy needles are used to punch the donor tissue specimens respectively. All the needles with the punched specimen cylinders are arrayed into the array-board, with an array of small holes dug to fit the needles. All the specimen cylinders arraying and the TMA paraffin block shaping are finished in only one step so that the specimen cylinders and the paraffin of the TMA block can very easily be incorporated and the recipient paraffin blocks need not be made in advance, and the paraffin used is the same as that for conventional pathology purpose. ZM-1 tissue microarrayer is easy to be manufactured, does not need any precision location system, and so is much cheaper than the currently used instrument. Our method＇s relatively cheap and simple ZM-1 tissue microarrayer technique of constructing TMA paraffin block may facilitate popularization of the TMA technology.     

关于优化推铅球左腿支撑技术结构的探讨

在田径运动中，推铅球是单手投掷的非周期性运动项目。推铅球时的技术方法与场地器械有其独特的特点，因而形成了独特的技术结构。推铅球同掷铁饼一样，都是在圆圈中投掷，左腿都有一个制动，支撑用力的动作，但是左腿用力是一个复杂的过程，而不仅仅是一个简单的动作形式，推铅球时，左腿在最后用力过程中，能否形成合球的支撑技术，对最后用力的效果影响极大。因此，本文就推铅球时如何优化运动技术结构，使之达到比较完善的效果，作一个初步探讨。

2011散打锦标赛中运动员抱腿摔法技术运用现状研究

摔法在比赛中成为最主要也是最常用的使用技法,抱腿摔又是摔法中的一个重要分支。文章主要通过对2011散打锦标赛抱腿摔技术运用情况进行探讨。研究表明：（1）在2011散打锦标赛的抱腿摔技术运用上,最常用抱大腿技法是下潜抱双腿、下潜抱单腿、抱腿下压、抱腿扛、抱腿旋五种技术;作为抱小腿摔法,最常用的是勾踢摔、接腿别、接腿前压等技术。（2）抱腿类摔法在小级别运用最高,但是从成功率角度来说小级别的成功率是非常低的,大级别最高。

Physical education teaching as a caring act—techniques of bodily touch and the paradox of caring

In this article, we investigate ‘no touch policies’ as a practical teacher concern that includes the body as a location, a source and a means in educational activity. We argue that to understand issues regarding physical touch within school practice we must conceive it as deeply associated with specific teaching techniques. Thus, the didactical challenge is not found in argumentations about the pro and cons of physical touch, but through analysis of how teachers handle student interaction and teaching intentions.

We consider teaching as a caring profession. Caring, as a practical teacher concern, requires wisdom regarding the right time to use bodily touch and to refrain from such use. This wisdom involves the ability to discern people’s needs, desires, interests and purposes in particular situations and act appropriately. From a body pedagogical perspective we approach intergenerational touch not only as a discursive and power-related question but as an essential tension in the intersection of the; ambiguity attendant to any intentional act such as teaching, the conflict between the ethics of care and the ethics of justice, and finally, the paradox of caring.

We draw on interviews with PE-teachers in Swedish primary, secondary and upper-secondary schools and analyses of a collection of techniques of bodily touch that are established and practiced with specific pedagogical purposes. The results shows PE teacher’s competence in handling different functions of intergenerational touch in relation to three different techniques of bodily touch; (1) Security touch, which is characterized by intentions to handle the fragile; (2) Denoting touch, which is characterized by intentions to handle learning content and (3) Relational touch, which is characterized by caring intentions. Each of these is of importance for the teachers in carrying out their call to teach and each of these relies on professional assessments whether or not it meets its intended purpose.
