The Elephаnts оf Sаmburu An Encоunter аt Sunset [A] Late оne afternoon, biologist Iain Douglas-Hamilton stopped by my tent and asked if I wanted to drive out and see some elephants before sunset. I asked him if he would like to take a walk instead. I knew that walking around the reserve could be risky, but surely we could at least climb the little hill just behind camp. He agreed, and we did. The view of the river from the top was magnificent. Just north of us was a larger hill known as Sleeping Elephant. I asked him if he had ever climbed that one. He told me he hadn't, but, with a mischievous look in his eye, said that we could. [B] We walked toward Sleeping Elephant: two middle-aged white men and a young Samburu man named Mwaniki. We walked only five minutes before we saw a female elephant with two babies ahead of us. We paused, admiring these noble creatures from a safe distance until they seemed to withdraw, and then we went on, unable to foresee that our lives were in danger. Seconds later, we looked up to see the female staring angrily at us from 70 meters away. Her ears were spread wide, showing us her agitation. [C] Mwaniki and I turned and ran, and we managed to put a safe distance between us and the elephant. Mwaniki continued to run all the way back to camp to get help. At first, Douglas-Hamilton also turned and ran - then thought better of it, turned back, threw his arms out, and yelled to stop the elephant. Sometimes this works, but the female kept coming. Douglas-Hamilton turned again and ran, but the elephant caught him as he tried to evade her. She lifted him and then threw him as he yelled for help. She stepped forward and stabbed her sharp, rigid tusks downward at him. Then she backed off about ten steps and paused. This was the moment, he told me later, when he had time to wonder whether he would die. [D] I ran back to Douglas-Hamilton, and to my surprise, he wasn't dead. After stabbing at him once and missing, the elephant had turned away. She went off to find her babies. Douglas-Hamilton was scratched, but not badly hurt; his shoes, glasses, and watch were gone, but he was OK. He stood up. Then a dozen people arrived from camp, and helped retrieve his things. [E] Afterwards, Douglas-Hamilton and I hypothesized about what had triggered the attack. It was possible that we surprised her. Perhaps it was her mother's instinct to defend her calves. It was also conceivable that she had recently been frightened by a lion and was in an agitated state. The more difficult question, however, was why, at the last minute, did she decide not to kill him? I suppose we will never know, but I like to think that, after confusing him with an enemy, she finally recognized in Douglas-Hamilton a genuine friend of elephants. Saving the Elephants [F] "If you had asked me when I was ten years old what I wanted to do," Douglas-Hamilton says, "I'd have said: I want to have an airplane; I want to fly around Africa and save the animals." Later, while studying zoology at Oxford University, he found his goals hadn't changed. "Science for me was a passport to the bush," he says, "not the other way around. I became a scientist so I could live a life in Africa and be in the bush." [G] Early in his career in Africa, he went to Tanzania as a research volunteer in Lake Manyara National Park. He bought himself a small airplane, which he could use for tracking elephants. There at Manyara, Douglas-Hamilton did the first serious study of elephant social structure and spatial behavior (which includes where they go and how long they stay there) using a radio tracking system. He also became the first elephant researcher to focus closely on living individual animals, not just trends within populations or the analysis of dead animals. He got to know individual elephants and their personalities, gave them names, and watched their social interactions. [H] Then came the difficult years of the late 1970s and '80s, when Douglas-Hamilton sounded the alarm against the widespread killing of African elephants. The killing was driven by a sudden sharp rise in the price of ivory and made easy by the widespread availability of automatic weapons. Douglas-Hamilton calculated elephant losses throughout Africa at somewhere above 100,000 animals annually. He decided to do something. [I] With funding from several conservation NGOs, Douglas-Hamilton organized an immensely ambitious survey of elephant populations throughout the continent. From the results, compiled in 1979, he figured that Africa then contained about 1.3 million elephants, but that the number was declining at too fast a rate. Some experts in the field disagreed, and the struggle between the two sides over elephant conservation policy in the 1980s became known as the Ivory Wars. [J] Douglas-Hamilton spent years investigating the status of elephant populations in Zaire, South Africa, Gabon, and elsewhere, both up in his airplane and on the ground. He flew into Uganda during the chaos that followed the collapse of the government of the time and saw the bodies of slaughtered elephants all over the national parks. "It was a dreadful time. I really spent a terrible 20 years doing that," he says now. However, his work helped greatly to support the 1989 decision under the Convention on International Trade in Endangered Species to abolish the international sale of ivory. [K] In 1997, Douglas-Hamilton came to Samburu National Reserve in Kenya. By that time, he had established his own research and conservation organization, Save the Elephants. Today, he divides his time between teaching a new generation of elephantologists and studying the movement of elephants using global positioning system (GPS) technology. The data he acquires from elephants wearing GPS collars is used by the Kenya Wildlife Service to provide better wildlife-management and land-protection advice to the government. Save the Elephants now has GPS tracking projects not just in Kenya but also in Mali, South Africa, and the Democratic Republic of the Congo. [L] Following the attack outside his camp, Douglas-Hamilton was able, using his equipment, to identify the elephant that threatened him as Diana, one of the females from a herd he had been tracking for some time. Diana was just like any other elephant - sensitive, unpredictable, and complex. Although her behavior on that afternoon had been violent, at the last moment she had made a choice. And not even Iain Douglas-Hamilton, with all his modern equipment and years of experience, can know exactly why she attacked him - or why she let him live. Douglas-Hamilton was the first elephantologist to ____.
A musicаl fоrm diаgrаmed as such: A - B
Ms. Mоnrоe, а 27-yeаr-оld womаn, presented with a progressive history of gait imbalance, hand incoordination, and "slurred speech." Her symptoms worsened around her menstrual periods and when she was nervous or fatigued; they had worsened slightly during a pregnancy. During the speech examination, she admitted to an approximately 10-year history of "slurred speech" that did not seem to be worsening. Conversational speech was characterized by occasional irregular articulatory breakdowns. Infrequently, rate was mildly slowed and multisyllabic words were produced with excess and equal stress. Prolonged "ah" was unsteady. Speech AMRs were slow but not noticeably irregular. What do you suspect is the underlying etiology of her condition?
Mr. Middletоn, а 63-yeаr-оld mаle, was hоspitalized 6 weeks after a left carotid endarterectomy at another institution. Postoperative difficulties included speech problems and right hemiparesis. Neurologic examination noted right hemiparesis, dysarthria, and nonfluent aphasia. Speech-language evaluation revealed mild comprehension difficulty and unintelligible writing because of right hemiparesis. His speech was telegraphic and characterized by revisions, hesitancy, and repetitions. He presented with reduced loudness, mild hoarseness, and mild articulatory distortions. A right central facial weakness was present. Do you recommend treatment? If so, which approaches might be appropriate? (Select all that apply)

Ms. McCreа, а 35-yeаr-оld wоman, with a histоry of a chronic progressive condition presented for consideration of thalamotomy to control severe bilateral upper limb tremor. Neurologic examination revealed hyperreflexia, pathologic reflexes, bilateral weakness, spasticity, impaired coordination, nystagmus, and severe resting postural and movement tremor. Neuropsychological assessment noted severe impairment of new learning and memory and generalized loss of intellectual abilities. During the speech evaluation, she reported a 1-year history of progressive speech difficulty. She had reduced facial and lingual strength. Her speech was characterized by slow rate, irregular articulatory breakdowns, breathy-hoarse voice quality, and hypernasality with nasal emission. Speech intelligibility was significantly reduced. What do you suspect is the etiology of her condition?
