For this critical intercultural inquiry, I as an Asian/Japanese transnational cisgendered gay man write my autoethnography of queer (or non-heteronormative) Asian–Black (dis)connections. Specifically, I challenge, interrogate, and problematize my queer intercultural production of desire and attraction as I engage in my critical autoethnographic interrogation of dialogues with five Asian/Japanese transnational gay men who have previously engaged in queer Asian–Black relationality. In so doing, I intend to create a potential point of departure to decenter the discursive and material effects of White gay normativity in the knowledge production of Asian queer male desire and attraction. 相似文献

We previously demonstrated the relationship between sidestepping performance and the preparatory state of ground reaction forces (GRFs). The present study investigated the effect of the preparatory state of GRFs on defensive performance in 1-on-1 subphase of basketball. Ten basketball players participated in 1-on-1 dribble game of basketball. The outcomes (penetrating and guarding) and the preparatory state of GRFs (non-weighted and weighted states, i.e. vertical GRFs below and above 120% of body weight, respectively) were assessed by separating the phases. In the non-weighted state and the weighted state to determine the outcome, the probability of successful guarding was 78.8% and 29.6%, respectively. The non-weighted state prevented delay of the defensive step in the determination phase. Both the non-weighted and weighted states, immediately before the determination phase, were likely to change to the weighted state in the determination phase; during this time, the defender's preparatory state would be destabilised, presumably by the dribbler's movement. These results revealed that the preparatory GRFs before the defensive step help to explain the outcome of the 1-on-1 subphase, and suggest a better way to prevent delaying initiation of the defensive step and thereby to guard more effectively against a dribbler. 相似文献

This article describes a method used to provide mathematics students in colleges of engineering in Japan with supplementary exercises to aid in their learning. The impact of this effort is also described. An online support function enables instructional personnel to individualize the exercise for students whose abilities vary widely. Individualizing exercises helps students to understand a mathematical method used to solve a problem and also the mathematical idea or concept upon which the method is based. The program described here consists of activities that supplement those in the regular lesson. They are designed to help those students who failed to meet certain course objectives or to solve the problems given in the lesson. Students using the individualized program are allowed to select the problems from among the problem exercises available based on the course objectives that they have not yet satisfied. The online support function of the learning environment that the authors developed assists teaching personnel in the otherwise time-consuming preparation of individualizing these activities. Students determine how well they did on the objectives in the regular lesson by visting the Web page for the course. Information is provided on the impact of the activities on student performance in a fundamental mathematics course in the authors college. 相似文献

The purpose of this study was to investigate the effect of lumbosacral kinetics on sprinting. Twelve male sprinters performed 50 m sprints at maximal effort. Kinematic and ground reaction force data were recorded at approximately 40 m from sprint commencement. A whole-body inverse dynamics approach was applied to calculate joint forces and torques at the hip and lumbosacral joints. The contribution of the hips and lumbosacral joint torques to pelvic rotation was subsequently calculated, with joint force powers indicating the rate of mechanical energy transfer between segments across joint centres calculated for both hip joints. The kinetic analysis indicated that the lumbosacral torsional torque contributed significantly to pelvic rotation. Additionally, the pelvic rotation exerted anterior–posterior joint forces on the hips, contributing to the large positive joint force power at the hip of the stance leg. These hip joint force powers assisted in motion recovery during sprinting. In conclusion, the lumbosacral torsional torque might contribute to the recovery motion in sprinting through application of the anterior–posterior joint forces at the hip joints via pelvic rotation. 相似文献

The effective numerical method proposed by Shimamuraet al. (2007) is extended to predict the ball motion in a draw shot as well as a follow shot in billiards. The extended method is
verified experimentally using a high speed camera. It is observed in the experiment that a ball rotates backwards with a lot
of slip (between ball and table) at first and then rotates forwards in a draw shot. Such a ball motion is predicted quantitatively
with the numerical method. Numerical simulations are performed to investigate the effects of material properties of a cue
on ball behaviour in follow and draw shots and it is found that the impact force increases with increasing stiffness of the
shaft in both follow and draw shots, while its duration time is shortened with increasing wave velocity in the shaft for both
shots. It is also found that there is a certain shaft stiffness that gives the minimum ball centre velocity, the minimum angular
velocity, the minimum slip velocity between ball and table and also the minimum time when the backward rotation changes to
a forward one in a draw shot, while the ball centre velocity and the angular velocity increase with increasing shaft stiffness
in a follow shot. 相似文献

We herein report a study on the intelligent control of microfluidic systems using reinforcement learning. Integrated microvalves are utilized to realize a variety of microfluidic functional modules, such as switching of flow pass, micropumping, and micromixing. The application of artificial intelligence to control microvalves can potentially contribute to the expansion of the versatility of microfluidic systems. As a preliminary attempt toward this motivation, we investigated the application of a reinforcement learning algorithm to microperistaltic pumps. First, we assumed a Markov property for the operation of diaphragms in the microperistaltic pump. Thereafter, components of the Markov decision process were defined for adaptation to the micropump. To acquire the pumping sequence, which maximizes the flow rate, the reward was defined as the obtained flow rate in a state transition of the microvalves. The present system successfully empirically determines the optimal sequence, which considers the physical characteristics of the components of the system that the authors did not recognize. Therefore, it was proved that reinforcement learning could be applied to microperistaltic pumps and is promising for the operation of larger and more complex microsystems. 相似文献

The CAST （content area specialized training） model of professional development enables sustainable teacher leadership and is responsive to the need for culturally relevant educational practices. The purpose of this paper is to share the background, methods, findings and recommendations of a case study on the CAST initiative in Guam. The case study is worth a look given that 100% of the participants in the CAST initiative indicated that they were satisfied with the CAST model of professional development. 相似文献

In this essay, we interrogate the ways in which the uncultural masks the cultural in ABC’s Dr. Ken. We analyze Dr. Ken’s first season, through the conceptual lens of strategic whiteness, to identify and critique the ambiguous and nuanced positions of Asian Americans. By repeatedly demonstrating the simultaneous functions of Asian Americans both as almost Whites and as (nonthreatening) Others, Dr. Ken resecures invisible territories of whiteness as property. Our goal is to disrupt the uncultural assumptions about Dr. Ken as it strategically draws attention away from its reproduction of norms of whiteness at the expense of Asian Americans. 相似文献

The aim of this study was to examine the effect of bilateral asymmetry of muscle strength on maximal height of the squat jump. A computer simulation technique was used to develop two kinds of 3D human lower limb musculoskeletal model (model-symmetry and model-asymmetry). The total muscle strength of the two models was set to be identical. Bilateral muscle strength was equal in the model-symmetry simulation, while the model-asymmetry simulation was performed with a 10% bilateral strength asymmetry. A forward dynamics approach was used to simulate squat jumps. The squat jumps were successfully generated, producing jump heights of 0.389 m for model-symmetry and 0.387 m for model-asymmetry. The small difference in height (0.5%) indicated that the effect of the 10% bilateral asymmetry of muscle strength on jump height is negligible. With model-asymmetry, the strong leg compensated for the muscle strength deficit of the weak leg. Importantly, the mono-articular and large extensor muscles of the hip and knee joint of the strong leg, including the gluteus maximus, adductor magnus, and vasti, compensated for the muscle strength deficit of the weak leg. 相似文献
