Effects of the Lower Half of the Body on Batting

The purpose of this study was to clarify the effects of the lower half of the body on batting performance with a comparative analysis among three different kinds of tee-batting. Those tee-battings were performed 1) with no restraints of movements on the lower half of the body (standing posture), 2) with a restraint of movements on the lower half of the body by sitting on a non-swivel chair (fixed posture), 3) with a restraint of movements on the lower half of the body by sitting on a swivel chair (turn posture).The subject in the experiment was an intermidiate-skilled baseball player, who was right-handed. The batting performances were recorded with EMG and a videocamera, and analyzed from a biomechanical viewpoint.The main results obtained were as follows:1) By comparison with the distance of a batted-ball at the standing posture, the percent-age of that at the fixed posture showed only 56.4%and58.7%was shown at the turn posture.2) Muscle activity of the upper half of the body at the fixed posture was different from that at the turn posture.3) It tended that the inclinations to the forward of right shoulder, right elbow and right wrist at the fixed and the turn posture were quicker than those at the standing posture.4) Horizontal movement of head at the fixed and the turn posture were larger than that at the standing posture. It seemed that the movement had an effect on the accuracy of batting.5) It was clear that the bat swing speed at the standing posture was quicker than that at the fixed and the turn posture.From the results above metioned, it was concluded that the lower half of the body was very important to the effective and speedy batting performance, so it was essential to make a careful consideration for a training load, coordination enhancement and a training period in order to provide a training program for the lower half of the body.

Winter Dream

shining eyes and smiled. "Imagine Cesar's face when he sees what you've brought home." "Grandpa's never caught one this big," Lamar said. "Nor Dad either." Jeff helped Lamar take the fish off the hook and put him on the stringer. He put the stringer in the minnow bucket. Lamar sat back down and began casting the fly toward the stump again. "Fifteen more minutes," Jeff said, "and we have to go." "Do we have to?" Lamar asked. "Your folks will be waiting for you," Jeff said, "and I need to get home." Lamar cast the fly over and over, but the water was still. There was only the pip of the fly hitting the water and an occasional plop as an acorn fell. All at once, acorns rained down. They sounded like flying gravel. "It's time to go," Jeff said. Lamar secured the rod and put it under the seat. "We'll go fishing again sometime," Jeff said. He started the motor, turned the boat, and opened it up. He was glad to leave the bluff behind and turn the boat toward the dock. He pulled the stick back, and the boat slowed down. When he docked, Lamar jumped out to hold the boat. He helped Jeff get the boat on the trailer, hook up the taillights, and secure everything. Jeff put the ice chest and the fishing tackle into the Bronco. Last of all, he took the stringer out of the minnow bucket and held it up. "A nice bass," he said. "It might be the championship first-fish-caught-on-afly -rod or all time." Lamar grinned. He started to take the fish off the stringer. Jeff shook his head. "Cesar can bring it to me tomorrow." "Thanks for taking me," Lamar said. He ran across to the men. His legs looked longer than life as he ran toward the big red sun, his shadow stretching across the parking lot, his head bobbing in the gravel. He held the fish out in front of him so the men could see it before he got there. They got up to admire it. Lamar and the men waved. Jeff waved back and turned to get in the Bronco. There was a nick in the paint near the door handle. He looked down at the scuff mark where he had kicked the mound of gravel. He sighed. A childish thing to do! But he was glad he had taken Lamar fishing. It had been good to watch a boy learning to cast a fly rod. He could almost imagine Anthony sitting there in the swivel chair, flicking a fly at a stump. Anthony was still too young for flyfishing , of course, but he was old enough to use a cane pole with a cork that bobbed up and down when he got a bite. Whistling the old gospel tune, "Joshua Fought the Battle of Jericho," Jeff got in the Bronco and started the engine. Perhaps it still wasn't too late to take Anthony for ice cream. Winter Dream We will meet spring in the Blue Ridge, with ice falls, fingerling trout, and bees in the apple orchard, when ghost cattle move from the old dairy barn, up the mountain, and spirit Cherokee stalk living deer. From beneath this winter's night we will move, somewhere in the blue mountain mist and brown mountain lights, to touch the warming stone, mist maker, keeper of legends. I will turn to you and there, with the turn of a linen shawl, you will recreate the world. —Ray Hackett 19 ...

Man killed crossing the road

‘Man killed crossing road’. It made headlines in all the tabloids. The secretaries working late in the pinchy little office blocks were agog. ‘Have you heard? Golly—it just goes to show’. They rocked forward in their swivel chairs, patting each other's knees to cry with delicious melodrama, ‘Could have happened to anyone—could have been … YOU even!’.

Effects of task attentiveness on task-irrelevant activity and boredom in the signal detection tasks

It has been reported that subsidiary behavior, including body movements, and irrelevant thoughts occur spontaneously during a vigilance situation. These activities are called task-irrelevant activity. To examine the effects of task attentiveness on task-irrelevant activity and on the subjective feeling of boredom, 31 subjects were asked to engage in two types of signal detection tasks. The body movements were measured by recording the rotating angle of a swivel chair that the subject sat on. More task-irrelevant thoughts and subsidiary behavior occurred accompanied by higher subjective feeling of boredom in the low attentive task than in the high attentive task. These findings indicate the possibility of the task-irrelevant activity as an index of subjective boredom.

An Evaluation of Chair Bases for Use On Carpet By Children With Cerebral Palsy

Children at the Mosman Spastic Centre Public School were assessed in carpeted classrooms to find a suitable chair that would promote independence. Four chair designs were compared and information recorded from aides, teachers, therapists and children. It was agreed that while the swivel chair and castor chair were unsuitable, the sled base design and rug runner attachments, two relatively new ideas, had a variety of advantages. A comparison between the two. detailing both the merits and the limitations. provides useful criteria for selecting a suitable classroom chair for the child with cerebral palsy.Since this project was started the chair with rug runners is being supplied on a regular basis throughout the school and is more recently being requested by parents for use at home. Unfortunately, the sled base, while a popular alternative, is only commercially available in an adult size. A smaller version of this chair using a variety of seat styles in preference to the polypropylene mould is currently being developed.

Interview

When, after NLW/LAR to‐ing and fro‐ing about a successor to Peter Labdon as editor of NLW, I took on the job, Roger Walter suggested that he interview me. He reminded me that I had interviewed him for LAR (November 1975) just before he became its first full‐time journalist editor. Some days later, and trying to see if there was something in it for NLW, I sat in the smoke‐filled LAR editorial office, swung about in the advertising executive's swivel chair, adjusted my green eye‐shade and suggested that RW and I interview each other and each publish the result in the other's journal. This whimsy was not pursued, but we did agree a date for a meeting, one or two topics we would discuss, and that the resultant interviews would be published without further consultation between us.

Down from Coeur d'Alene

DOWN FROM COEUR d'ALENE / Dan Thrapp AT NIGHTFALL, when they stopped across the river from Lewiston, m\ Mary Ann was not crying and said she would only be a minute. She got out of the jeep. Kyle put the gun in his belt, zipped up his jacket, and got out after her. The station was a teepee made of concrete with zig-zag Indian designs painted around its base. Inside, an attendant turned in his wooden swivel chair as the door opened. He was an Indian, a teenaged boy—black-haired, brown-eyed. He was thin. His head was square. He asked if Kyle wanted the key to the men's room. "It's kept locked," he said. Kyle stepped in, leaving the door open. "I'm okay." He looked at the room, at the counter, the cash register on the counter, the stacks of oil cans and brake fluid and gas treatment on shelves along the wall that separated the office from the restrooms. He looked at the fan belts looped on hooks above the shelves, at the green and brown linoleum on the floor, at the wooden desk, at the boy again. "It's her that needs to pee," he said. "She's my little girl. How old are you?" "Sixteen." The Indian boy smiled, his teeth large, white. "That's how old she is." Kyle cocked one hip and broke wind. "There, that's my name. Now tell me yours." The boy looked away and then looked at him again. "It's Jerome." "Jerome," Kyle said. He said the name again, drawing the name out slowly. "I like it. Funny name for an Indian. You're Indian, aren't you? You're from Lapwai. What's your last name?" Jerome blinked as he looked at Kyle. Kyle's shoulders were heavy and round. His butchcut hair had no color in the station's fluorescent light. "It's Crowshoe," Jerome said. "There you go. That's an Indian name. Nez Perce. Nay Persay, right?" Jerome looked down at his hands and then through the window toward Kyle's jeep parked at the edge of the concrete apron. "But Jerome," Kyle said. He took out a cigarette. "That's not a good name for an Indian. I ought to call you Tonto or something." "Crap," Jerome said, showing his teeth again. "That's funny isn't it?" Kyle grinned and opened the cap on his lighter and lit his cigarette. He turned away from Jerome to inspect the packages of potato chips and corn chips and Cheetos clipped to the display rack on the counter next to the register. He selected Cheetos and split the bag open. "You want to share these, Jerome?" "You got to pay for that," Jerome said. 224 · The Missouri Review Kyle grinned again. "AU right. But let me show you something now. You got spunk." He crossed the room to the boy. He put his boot on the space of chair between the boy's legs, and Jerome shifted, but the tip of the boot touched where the inseam crossed the center seam of the boy's jeans. "Look at this," Kyle said and unzipped his jacket. Light glinted on the silver buckle of Kyle's belt and on the black pistol tucked in beside it. Jerome's brown eyes looked at the gun and then calmly at Kyle. "It's a forty-five, Jerome. Big and mean. What do you think of that, little buck?" Jerome kept his hands on his knees, but his thick Indian lips slackened outward. "You going to rob me?" Kyle took his boot off the edge of the chair. "You're a good Indian," he said. "You know about these things. I like you, Jerome Crowfoot." He exhaled smoke at the boy. "It's no matter. I might rob you. I might shoot you, but Mary Ann's in the potty, so we can wait. She'll be in there for a time. We're all the way down from Coeur d'Alene. I didn't need to stop, but she had to. She couldn't wait till we crossed the river." Kyle shook his head. "Damn...

Nystagmic response to triangular wave-like rotatory stimulation.

The subject was allowed to sit on a swivel chair with nonpolarizing electrodes placed at the outer canthus of the eyes and on the forehead and with his head tilted 30° forward in order to study the nystagmus evoked by rotatory movements of the body, accelerated and decelerated at an equal rate.The velocity of the slow component of nystagmus was increased with an increase in the velocity of rotation of the chair, and decreased as the chair was decelerated after the maximum velocity was reached. The direction of nystagmus was reversed before the chair was stopped.A theoretical formula is available by which to calculate the π/Δ for the cupula from the magnitude and duration of accelereation and the time of reversion of the direction of nystagmus on the assumption that the endolymph system within the cupula represents a damped torsion pendulum. The π/Δ for the cupula at an acceleration of stimulus of 2°/sec2, 3°/sec2, 4°/sec2, 5°/sec2, 6°/sec2, 7°/sec2, 8°/sec2 and 9°/sec2 as calculated by using the formula was 19sec, 14sec, 23sec, 31sec, 32sec, 22.5sec and 22sec respectively.A π/Δ of 16sec was obtained when the duration of postrotatory nystagmus was employed as a basis of calculation.The value for π/Δ was found to vary with different magnitudes of acceleration, even in the same subject. thus, further studies are required to refine the theoretical formula and the method of stimulation.

The college deanship: A new middle management in higher education

I make no effort to be impartial on this point. Education is too important a business to be left to deans. The deanly condition is the condition of ignorance camouflaged by secretaries, charts, IBM cards, and statistics, but ignorance is occupational. Let a good man be trapped into a dean's swivel chair and his inhumane ignorance grows upon him as a condition of his employment. The only real difference between the arrogant and the apologetic deans is that the apologetic ones know to what extent their work drains them of mentality. How can one leave educational decisions to men who lack the time to read a book?2

Experiments on the r.n.s. (real nervous system) and monkey memory.

I am afraid that I find a title such as 'The logical analysis of cerebral functions’ irresistible. With what can it be contrasted except ‘The illogical analysis of cerebral functions’ ? Logic is a set of rules that allows one to deduce certain conclusions from certain assumptions. It is best carried out while sitting in an armchair or, nowadays, in a swivel chair in front of a computer console. But, of course, everything depends on the assumptions, and given any set of assumptions it is only a matter of time before, in principle, all possible conclusions can be listed exhaustively. Then, one can compare some of the conclusions with actual empirical results, provided one has the necessary connecting assumptions. This is a classical strategy. But given the peculiar past history and present state of our knowledge about cerebral functions, I am afraid that I am driven to embrace a contrasting approach of an ‘illogical analysis of cerebral functions’. Or, perhaps I should say I prefer an analysis of cerebral function that depends on inference rather than deduction. Deduction is an all-or none affair. It either leads to the brilliant break-through or to the scrap heap, or at least to the repair shop for patching or remoulding. In the history of our subject the scrap merchants have grown rich. I prefer a state of affairs where the assumptions stem from the conclusions rather than the conclusions from the assumptions. The problem of the analysis of cerebral function, as I see it, is that an organism both behaves, with all that can be elaborated by that word, and it also possesses a brain. But the two universes of discourse are quite different—there is nothing that we can say in making an assertion about the possession of a cranium that overlaps with descriptions about behaviour, except that without such a possession no behaviour is displayed for long. That is not a remarkable statement nor even one restricted to possession of an intact cranium: it applies equally forcefully to other vital organs. But somehow we have reached the point where we have more than a shrewd suspicion that the two are not independent—and it is by no means immediately obvious that they are not, as evidenced by the Greek hypothesis that the brain was a device merely for cooling the blood. But how do we study the mutual interaction? I suspect that one rather good way is by following the same steps that have already led us, over the centuries, to the firm view that there is some connexion between brain and behaviour. But progress has been painfully slow, and we are impatient.

The How to Study Problem

Strawberries may come and strawberries may go, but we have with us always. ' ' In such words the comedian calls atten tion to the prevalence of the commonplace in our lives and the occa sional sporadic spurt of genius. If he were reviewing the nature of our educational progress of the last half century he would no doubt find prunes everywhere, but the luscious fruit would be in evidence on rare occasions and its seasons of short duration. If he were limiting the scope of his activity still further and would apply his pun to our attempt to solve the how to problem I fear that he would hardly find enough genius to permit the green berry to assume a hue so deep as to make it tempting. A review of our attempt to solve this problem reveals an abun dance of activity within the realm of mediocrity?an abundance of swivel chair opinion, an abundance of generalizations from a few stray and often manipulated facts, a verbosity which has been equalled only, in the past and present, by new sciences in embryo.1 A. We started our attempt when the educator was not a sci entist, but when his chief problem consisted of selling his wares, of convincing the public that to study is a mark of good breeding, of culture, and when how to had to be interspersed with an abundance of what to in order to make the product salable. Whether the advice came from the pen of a Locke or Bacon, a Watts or Sandwick, whether written in the seventeenth or the nineteenth or twentieth century the same motive dominated the writer and the same method was used, the difference in genius probably being reflected by the degree of development of the embryo science at the time the advice was penned. B. In the course of time a new science was conceived and its embryo began a rapid development. Its growth was more rapid
