Operationalizing physical literacy for learners: Embodying the motivation to move

Physical literacy is a concept that is expected to encompass the mind and body in an integrated way to explain, promote, and help sustain human beings＇ fundamental function： movement. According to Whitehead（2010）, physical literacy is defined by motivation, especially by competence-based and interest-based motivation. This point of view is consistent with vast amount of research evidence on children and adolescents＇ physical activity behavior. In the article I attempt to interpret and operationalize physical literacy from a perspective that children＇s motivation in physical education is both an innate mental disposition and an acquired/learned attribute. Particularly I rely on the conceptual learning theory and motivation regulation mechanisms of the self-determination theory to argue that in physical education, children should experience tasks that inspire them to embody competence and interest along with self-regulation strategies necessary for developing and sustaining the motivation to move.

Wittgenstein on the Experience of Meaning： Historical and Contemporary Perspectives

This paper discusses a neglected theme in Wittgenstein＇s writings on meaning and psychology from the early 1930s until 1949. Throughout this period Wittgenstein deals with aspects of meaning of words and pictures that cannot be accounted for in dispositional terms but have to be related to experience and perception. Wittgenstein＇s reading of William James, I argue, has sharpened his eye for the many pitfalls in coming to terms with this experiential notion of meaning. James＇s treatment of experiences of meaning succumbs to the temptation to postulate ~~meaning-bodies,＂ bearers of meaning apart from the way and context in which we use the particular words. I argue that the conflation of what Wittgenstein calls the transitive and intransitive use of words is at the root of postulating meaning-bodies. I also argue that contemporary treatments of experiences of meaning are similarly vulnerable to James＇s confusion.

Numerical assessment on improving multistage centrifugal impeller performance by changing inlet skew angle at impeller inlet

Multistage centrifugal impellers with four different skew angles were investigated by using computational fluid dynamics.The purpose of this work is to investigate the influences of lean angle at the blade tip of the impeller inlet.Four variations of lean angles,that is,8°,10°,15° and 20°,were made at first stage impeller.Reynolds Average Navier Stokes equation was used in simulation together with a shear?stress transport(SST) k-w turbulence model and mixing-plane approach,respectively.Three dimensional fluid flows were simplified using periodic model to reduce the computational cost and time required.A good performance was expected that the secondary flow can be effectively reduced in the flow passage of the impeller without excessive increase in manufacturing cost caused by the secondary flow.The results show that secondary flow affects the main flow intricately to form vortices or having non-uniform velocity in the flow passage,which in turn results in substantial fluid energy loss not only in the impeller but also in the guide vane downstream of impeller.The numerical solutions were performed and allowed the optimum design and operating conditions to be obtained.

Analysis on the Implicit Internet Attitude of the Internet Addicts and the Intervene Problems

Implicit Internet attitude refers to the implicit, automatic psychological tendency of an individual toward the Internet. A study found that Internet addicts held an implicit attitude and positive evaluation toward the Intemet, and this type of evaluations could be effectively changed through subliminal evaluative conditioning technology. An investigation on IAT effect showed the implicit attitude of the Intemet addicts was stable and variable, and AIA （ambivalence of implicit attitudes） might be an integrated perspective to solve the problem.

The Relationship between AIDS High Risk Behaviors and Childhood Status, Perception of Gender Orientation and Rare Experiences/Psychology among Chinese Gays

Objectives: To probe some more important factors affecting the HIV epidemic by surveying the relationshipbetween AIDS high risk behaviors and childhood status,attitude/perception to gender of male/sex orientation andrare experiences/Psy-chology among Chinese gays. Methods: Data were collected from 240 Chinese gays whowere attracted by their same gender. Results: The extent of sex among China's Mainland gays issimilar to that of industrialized countries, and behaviorsthat exacerbate the HIV epidemic are universal.Perceptions 'being a girl is better',' Dislike toys likeswords or pistols in early childhood were predictors topassive anal intercourse in adulthood. Those gay men whobegan sexual intercourse younger than 16 years old tendedto have more sex partners and suffered more pain. Thosedisliked gender of male or self-regarded as female tended tohave more passive anal intercourse and related to childhoodcross-gender experience/psychology while those were raised as girls by their parentsdid not take on e above characters. Individuals who experienced sex coercion and drug abuse were the twosubgroups with the greatest high-risk behaviors. Individualswho had sex with females had the greatest number of malesex partners and were more prone to group sex. Individualswith pedophilia or gerontophilia had more casual sexpartners. Psychological problems encountered by Chinese Conclusions: The prospect of an extensive AIDSepidemic among Chinese gays does exist and somesubgroups of gays play more important roles in theepidemic. Some high risk behaviors among adult gays canbe foreseen explicitly by the predictors taking on inchildhood, and closely relate to attitude/perception, togender of male, to some rare experience/psychology.

Evaluation of mixed-mode stress intensity factors by extended finite element method

Extended finite element method （XFEM） implementation of the interaction integral methodology for evaluating the stress intensity factors （SIF） of the mixed-mode crack problem is presented. A discontinuous function and the near-tip asymptotic function are added to the classic finite element approximation to model the crack behavior. Two-state integral by the superposition of actual and auxiliary fields is derived to calculate the SIFs. Applications of the proposed technique to the inclined centre crack plate with inclined angle from 0° to 90° and slant edge crack plate with slant angle 45°, 67.5° and 90° are presented, and comparisons are made with closed form solutions. The results show that the proposed method is convenient, accurate and computationallv efficient.

DIAGNOSTIC VALUE OF DENSITY GRADIENT CENTRIFU-GATION FOR EXFOLIATIVE TUMOR CELLS IN MALIG-NANT PLEURAL EFFUSIONS

Objective To find out a specific method for diagnosis of malignant pleural effusions (MPEs)with higher sensitivity and practicality. Methods The diagnosis of MPEs were made using density gradient cen-trifugation(DGC) , smear cytologic examination( SCE) and pleural needle biopsy (PNB). Comparisons between these results and those of benign pleural effusions were also made. Results The positive rates of DGC,SCE and PNB for diagnosing MPEs were 94. 3% ,62. 9% and 44. 6% , respectively, and the positive rate of SCE combined with PNB for diagnosing MPEs was 73. 2%. The positive rate of the exfoliative tumor cells ( ETCs ) by DGC was much higher than that of SCE or/and PNB with no false-positive. Conclusion The ETCs isolated by DGC from the MPEs is quite specific for the diagnosis of malignant tumors with higher sensitivity and practicality in clinico-patho-logical practice.

Comparisons between centrifuge and numerical modeling results for slope toppling failure

This paper presents series studies on the toppling mechanism by centrifuge tests and numerical simulations. Two different discrete element methods, i.e., the continuum-based discrete element method(CDEM) and the discontinuous deformation analysis(DDA), are adopted. The modeling results show that both the methods can accurately capture the failure modes of the centrifuge tests, including three distinct zones and two failure surfaces. Comparisons are made between the physical test and numerical simulation results. The critical inclination angle of the tilting table where the slope models are fixed on can be moderately predicted by the two methods, with different degrees of precision. The error between the test results and the simulated results is within 1% for the slope models without rock-bridges by both CDEM and DDA. However, it is amplified for the staggered-joint models that simulate the rock-bridges. With DDA, the average error is about 5%, and the maximum error is up to 17%. While with CDEM, the errors for the aligned-joint models are ranged from 1% to 6%, and it is from 10% to 29% for the staggered-joint models. The two numerical methods show the capability in simulating toppling failure of blocky rock mass with and without rock-bridges. The model with rock-bridges which provides a certain bending resistance is more stable than the one without any rock-bridge. In addition, the two failure surfaces were observed, which is different from the common understanding that only one failure surface appears.
