LSD :: Hallucinogens Drugs Essays

LSD Lysergic Acid Diethyl amide (LSD) has been implicated in a variety of studies to determine its potential for influence on certain neural activities. To date, little that can be certified as concrete fact has been found, though a number of theories with considerable support exist. Although dopamine, epinephrine, and norepinephrine may be implicated in some LSD studies, serotonin seems to be the main focus of scientific inquiry with respect to LSD. Leicht (1996), postulates four theories concerning serotonin (5-HT) pre- and post- synaptic transmitter sites and the potential for LSD to affect these sites, in particular. All of these theories point to the synaptic neuronal dendrites and terminal buttons as the main suspects with regard to LSD and its particular target area on the neurons themselves. After considerable dialogue which analyses studies by Aghajanian and colleagues, Leicht came to the conclusion that the evidence points toward certain types of activities on particular pre- and post-synaptic serotonergic neurons. The theories are as follows: 1: LSD Pre-synaptically inhibits 5-HT neurons. 2: LSD Post-synaptically antagonizes 5-HT2 receptors. 3: LSD Post-synaptically partially agonizes 5-HT receptors. 4: LSD Post-synaptically agonizes 5-HT receptors. Neural clusters in the Raphe Nuclei, which spread out from there, mainly into the frontal and prefrontal cortices have been identified as serotonergic. They are also auto-reactive, and LSD appears to inhibit the spontaneous firing of the neurons at that site, when the drug is systemically administrated. 5-HT2 receptors have been identified as pH dependent, while LSD molecules have been identified as pH independent. 5-HT2 receptors are connected to a second messenger system (phosphatidyloniitol, or PI). PI turnover has been found to be affected by 5-HT2 in an antagonistic fashion, but is stimulated by 5-HT. LSD, in micrometric doses, can inhibit 1000 times that amount of 5-HT, which supports theory #2, as well as supporting, partially, theory #3; when LSD is administered in a variety of doses, it apparently acts as a partial agonist. Though LSD and 5-HT are highly compatible, 5-HT is more effective at the serotonin receptor site, but LSD can compete with it at the 5-HT2 site. The conclusion is, â€Å"†¦since 5-HT is a more potent agonist than LSD, the effects of LSD would appear antagonistic.â€Å" Finally, for theory #4, Leicht cites Dr. Glennon’s explanation of LSD’s relationship with post-synaptic 5-HT receptors.

Johne Donnes the Flea Essay -- John Donne

â€Å"The Flea† John Donne observes a typical bar, every Saturday night sweat drenched bodies emitting alcohol and pheromones from every pore, exchange conversation, pleasantries, and yes even sex (perhaps not directly in view but certainly eluded to). Is this animalistic, barbaric behavior acceptable? Should sex be taken so lightheartedly? Or do we take it too seriously, guarding sex like it was the Holy Grail, or the secret to life itself? These questions may be to deep and pointed for most to approach, yet John Donne in his poem â€Å"The Flea† wades through them like the kiddy pool. In this clever poem Donne uses a flea, blood, and the murder of the flea as an analogy for the oldest most primal exchange, sex. Donne, through symbolic images, not only questions the validity of coveting virginity but also the importance of sex as it pertains to life. The metaphors in â€Å"The Flea† are plentiful, but the symbols repeated throughout the poem are clear, beginning with the most prevalent, and the flea. This small parasitic creature is chalk full of symbolic meaning. During the time this poem was written (the Renaissance) the flea was use in many poems about sex. I derive that in this particular poem the flea is symbolic of the act of sex from the speaker’s remark in the beginning, â€Å"Mark but this flea, and mark in this, how little that which deniest me is† the flea is small and inconsequential, his lady denies him sex, which the speaker believes is also petty. The flea is described as a marriage temple and a carrier of life, but in the next stanza as something insignificant and small. The speaker applies a certain duality to the flea and therefore to sex. The metaphor develops more as it relates to the other symbols. Blood is used more than once a... ...e feminine population. In this poem the speaker does not seem to be very respectful of the female he is pursuing. Of course that is conducive to the time but it also says something about the validity of the message of the poem. In synopsis the flea, blood and death of the flea are all used as metaphors for sex, the exchange of life force (a very important thing) within the act of sex (represented as something as insignificant as a flea) and then orgasm, which can feel important and significant for a period of time but is really only as important as the death of a flea. The speaker in this poem hopes to convince his lady to sleep with him by trivializing sex and comparing it to something as insignificant as a flea. Meanwhile I say lady, screw the speaker and the flea you would get more of a commitment from a machine than a guy as afraid of human contact as this one.

Part Four Chapter X

X At nine o'clock on the morning of the election for Barry's seat, Parminder left the Old Vicarage and walked up Church Row to the Walls' house. She rapped on the door and waited until, at last, Colin appeared. There were shadows around his bloodshot eyes and beneath his cheekbones; his skin seemed to have thinned and his clothes grown too big. He had not yet returned to work. The news that Parminder had screamed confidential medical information about Howard in public had set back his tentative recovery; the more robust Colin of a few nights ago, who had sat on the leather pouffe and pretended to be confident of victory, might never have been. ‘Is everything all right?' he asked, closing the door behind her, looking wary. ‘Yes, fine,' she said. ‘I thought you might like to walk down the church hall with me, to vote.' ‘I – no,' he said weakly. ‘I'm sorry.' ‘I know how you feel, Colin,' said Parminder, in a small tight voice. ‘But if you don't vote, it means they've won. I'm not going to let them win. I'm going to go down there and vote for you, and I want you to come with me.' Parminder was effectively suspended from work. The Mollisons had complained to every professional body for which they could find an address, and Dr Crawford had advised Parminder to take time off. To her great surprise, she felt strangely liberated. But Colin was shaking his head. She thought she saw tears in his eyes. ‘I can't, Minda.' ‘You can!' she said. ‘You can, Colin! You've got to stand up to them! Think of Barry!' ‘I can't – I'm sorry – I †¦' He made a choking noise and burst into tears. Colin had cried in her surgery before now; sobbed in desperation at the burden of fear he carried with him every day of his life. ‘Come on,' she said, unembarrassed, and she took his arm and steered him through to the kitchen, where she handed him kitchen roll and let him sob himself into hiccups again. ‘Where's Tessa?' ‘At work,' he gasped, mopping his eyes. There was an invitation to Howard Mollison's sixty-fifth birthday party lying on the kitchen table; somebody had torn it neatly in two. ‘I got one of those, as well,' said Parminder. ‘Before I shouted at him. Listen, Colin. Voting – ‘ ‘I can't,' whispered Colin. ‘ – shows them they haven't beaten us.' ‘But they have,' said Colin. Parminder burst out laughing. After contemplating her with his mouth open for a moment, Colin started to laugh too: a big, booming guffaw, like the bark of a mastiff. ‘All right, they've run us out of our jobs,' said Parminder, ‘and neither of us wants to leave the house but, other than that, I think we're in very good shape indeed.' Colin took off his glasses and dabbed his wet eyes, grinning. ‘Come on, Colin. I want to vote for you. It isn't over yet. After I blew my top, and told Howard Mollison he was no better than a junkie in front of the whole council and the local press – ‘ He burst out laughing again and she was delighted; she had not heard him laugh so much since New Year, and then it had been Barry making him do it. ‘ – they forgot to vote on forcing the addiction clinic out of Bellchapel. So, please. Get your coat. We'll walk down there together.' Colin's snorts and giggles died away. He stared down at the big hands fumbled over each other, as if he were washing them clean. ‘Colin, it's not over. You've made a difference. People don't like the Mollisons. If you get in, we'd be in a much stronger position to fight. Please, Colin.' ‘All right,' he said, after a few moments, awed by his own daring. It was a short walk, in the fresh clean air, each of them clutching their voter registration cards. The church hall was empty of voters apart from themselves. Each put a thick pencil cross beside Colin's name and left with the sense that they had got away with something. Miles Mollison did not vote until midday. He paused at his partner's door on the way out. ‘I'm off to vote, Gav,' he said. Gavin indicated the telephone pressed against his ear; he was on hold with Mary's insurance company. ‘Oh – right – I'm off to vote, Shona,' said Miles, turning to their secretary. There was no harm in reminding them both that he was in need of their support. Miles jogged downstairs and proceeded to the Copper Kettle, where, during a brief post-coital chat, he had arranged to meet his wife so that they could go down to the church hall together. Samantha had spent the morning at home, leaving her assistant in charge at the shop. She knew that she could no longer put off telling Carly that they were out of business, and that Carly was out of a job, but she could not bring herself to do it before the weekend and the concert in London. When Miles appeared, and she saw his excited little grin, she experienced a rush of fury. ‘Dad not coming?' were his first words. ‘They're going down after closing time,' said Samantha. There were two old ladies in the voting booths when she and Miles got there. Samantha waited, looking at the backs of their iron-grey perms, their thick coats and their thicker ankles. That was how she would look one day. The more crooked of the two old women noticed Miles as they left, beamed, and said, ‘I've just voted for you!' ‘Well, thank you very much!' said Miles, delighted. Samantha entered the booth and stared down at the two names: Miles Mollison and Colin Wall, the pencil, tied to the end of a piece of string, in her hand. Then she scribbled ‘I hate bloody Pagford' across the paper, folded it over, crossed to the ballot box and dropped it, unsmiling, through the slot. ‘Thanks, love,' said Miles quietly, with a pat on her back. Tessa Wall, who had never failed to vote in an election before, drove past the church hall on her way back home from school and did not stop. Ruth and Simon Price spent the day talking more seriously than ever about the possibility of moving to Reading. Ruth threw out their voter registration cards while clearing the kitchen table for supper. Gavin had never intended to vote; if Barry had been alive to stand, he might have done so, but he had no desire to help Miles achieve another of his life's goals. At half-past five he packed up his briefcase, irritable and depressed, because he had finally run out of excuses not to have dinner at Kay's. It was particularly irksome, because there were hopeful signs that the insurance company was shifting in Mary's favour, and he had very much wanted to go over and tell her so. This meant that he would have to store up the news until tomorrow; he did not want to waste it on the telephone. When Kay opened the door to him, she launched at once into the rapid, quick-fire talk that usually meant she was in a bad mood. ‘Sorry, it's been a dreadful day,' she said, although he had not complained, and they had barely exchanged greetings. ‘I was late back, I meant to be further on with dinner, come through.' From upstairs came the insistent crash of drums and a loud bass line. Gavin was surprised that the neighbours were not complaining. Kay saw him glance up at the ceiling and said, ‘Oh, Gaia's furious because some boy she liked back in Hackney has started going out with another girl.' She seized the glass of wine she was already drinking and took a big gulp. Her conscience had hurt her when she called Marco de Luca ‘some boy'. He had virtually moved into their house in the weeks before they had left London. Kay had found him charming, considerate and helpful. She would have liked a son like Marco. ‘She'll live,' said Kay, pushing the memories away, and she returned to the potatoes she was boiling. ‘She's sixteen. You bounce at that age. Help yourself to wine.' Gavin sat down at the table, wishing that Kay would make Gaia turn the music down. She had virtually to shout at him over the vibration of the bass, the rattling saucepan lids and the noisy extractor fan. He yearned again for the melancholy calm of Mary's big kitchen, for Mary's gratitude, her need for him. ‘What?' he said loudly, because he could tell that Kay had just asked him something. ‘I said, did you vote?' ‘Vote?' ‘In the council election!' she said. ‘No,' he replied. ‘Couldn't care less.' He was not sure whether she had heard. She was talking again, and only when she turned to the table with knives and forks could he hear her clearly. ‘†¦ absolutely disgusting, actually, that the parish is colluding with Aubrey Fawley. I expect Bellchapel will be finished if Miles gets in †¦' She drained the potatoes and the splatter and crash drowned her temporarily again. ‘†¦ if that silly woman hadn't lost her temper, we might be in with a better shot. I gave her masses of stuff on the clinic and I don't think she used any of it. She just screamed at Howard Mollison that he was too fat. Talk about unprofessional †¦' Gavin had heard rumours about Dr Jawanda's public outburst. He had found it mildly amusing. ‘†¦ all this uncertainty's very damaging to the people who work at that clinic, not to mention the clients.' But Gavin could muster neither pity nor indignation; all he felt was dismay at the firm grip Kay seemed to have on the intricacies and personalities involved in this esoteric local issue. It was yet another indication of how she was driving roots deeper and deeper into Pagford. It would take a lot to dislodge her now. He turned his head and gazed out of the window onto the overgrown garden beyond. He had offered to help Fergus with Mary's garden this weekend. With luck, he thought, Mary would invite him to stay for dinner again, and if she did, he would skip Howard Mollison's sixty-fifth birthday party, to which Miles seemed to think he was looking forward with excitement. ‘†¦ wanted to keep the Weedons, but no, Gillian says we can't cherry-pick. Would you call that cherry-picking?' ‘Sorry, what?' asked Gavin. ‘Mattie's back,' she said, and he had to struggle to recollect that this was a colleague of hers, whose cases she had been covering. ‘I wanted to keep working with the Weedons, because sometimes you do get a particular feeling for a family, but Gillian won't let me. It's crazy.' ‘You must be the only person in the world who ever wanted to keep the Weedons,' said Gavin. ‘From what I've heard, anyway.' It took nearly all Kay's willpower not to snap at him. She pulled the salmon fillets she had been baking out of the oven. Gaia's music was so loud that she could feel it vibrating through the tray, which she slammed down on the hob. ‘Gaia!' she screamed, making Gavin jump as she strode past him to the foot of the stairs. ‘GAIA! Turn it down! I mean it! TURN IT DOWN!' The volume diminished by perhaps a decibel. Kay marched back into the kitchen, fuming. The row with Gaia, before Gavin arrived, had been one of their worst ever. Gaia had stated her intention of telephoning her father and asking to move in with him. ‘Well, good luck with that!' Kay had shouted. But perhaps Brendan would say yes. He had left her when Gaia was only a month old. Brendan was married now, with three other children. He had a huge house and a good job. What if he said yes? Gavin was glad that he did not have to talk as they ate; the thumping music filled the silence, and he could think about Mary in peace. He would tell her tomorrow that the insurance company was making conciliatory noises, and receive her gratitude and admiration †¦ He had almost cleared his plate when he realized that Kay had not eaten a single mouthful. She was staring at him across the table, and her expression alarmed him. Perhaps he had somehow revealed his inner thoughts †¦ Gaia's music came to an abrupt halt overhead. The throbbing quiet was dreadful to Gavin; he wished that Gaia would put something else on, quickly. ‘You don't even try,' Kay said miserably. ‘You don't even pretend to care, Gavin.' He attempted to take the easy way out. ‘Kay, I've had a long day,' he said. ‘I'm sorry if I'm not up to the minutiae of local politics the second I walk – ‘ ‘I'm not talking about local politics,' she said. ‘You sit there looking as if you'd rather be anywhere else – it's – it's offensive. What do you want, Gavin?' He saw Mary's kitchen, and her sweet face. ‘I have to beg to see you,' Kay said, ‘and when you come round here you couldn't make it clearer that you don't want to come.' She wanted him to say ‘that's not true'. The last point at which a denial might have counted slunk past. They were sliding, at increasing speed, towards that crisis which Gavin both urgently desired and dreaded. ‘Tell me what you want,' she said wearily. ‘Just tell me.' Both could feel the relationship crumbling to pieces beneath the weight of everything that Gavin refused to say. It was with a sense of putting them both out of their misery that he reached for words that he had not intended to speak aloud, perhaps ever, but which, in some way, seemed to excuse both of them. ‘I didn't want this to happen,' Gavin said earnestly. ‘I didn't mean it to. Kay, I'm really sorry, but I think I'm in love with Mary Fairbrother.' He saw from her expression that she had not been prepared for this. ‘Mary Fairbrother?' she repeated. ‘I think,' he said (and there was a bittersweet pleasure in talking about it, even though he knew he was wounding her; he had not been able to say it to anyone else), ‘it's been there for a long time. I never acknowledged – I mean, when Barry was alive I'd never have – ‘ ‘I thought he was your best friend,' whispered Kay. ‘He was.' ‘He's only been dead a few weeks!' Gavin did not like hearing that. ‘Look,' he said, ‘I'm trying to be honest with you. I'm trying to be fair.' ‘You're trying to be fair?' He had always imagined it ending in a blaze of fury, but she simply watched him putting on his coat with tears in her eyes. ‘I'm sorry,' he said, and walked out of her house for the last time. On the pavement, he experienced a rush of elation, and hurried to his car. He would be able to tell Mary about the insurance company tonight, after all.

Essay on Bede’s Ecclesiastical History of the English People

England has always been a strong point of Christianity, as such, the difficult times that came from the conquest of the territory by the Romans up to the moment when finally Henry VIII decides to separate from the Vatican and â€Å"their deceptions†; making of England one of the most important places where Christian history has been made.During such times of change, despite the different forces that shaped and misshaped the path of faith and religion in England, some conducts remained unchanged such as the belief that a person should focus only in what was adequate according to the standards that the Vatican had stated that were adequate.The first four chapters of Bede’s book only refer to England in the way it was formed, the benefits and paradisiacal surroundings that both England and its surrounding neighbours had to offer in terms of water, soil, vegetation and even animals. In the first book, Bede makes a strong point of reference in the martyrdom that British Chri stians suffered at the hands of the Roman conquistador empire. It is interesting the difference between other martyr books and references to the ones that Bede states in the book. Jack 2Here, therefore, the head of most courageous martyr was struck off, and here he received the crown of life, which God has promised to those who love Him. But he who gave the wicked stroke, was not permitted to rejoice over the deceased; for his eyes dropped upon the ground together with the blessed martyr's head. (Bede, Book 1:VII, 51-52) Other accounts only make strong points of the punishment that God allegedly gives those who inflict the martyrdom in cases against the female virtue and those where the executor is a member of their own family.Though it is not evidently put, the writing of Bede actually infers that God will claim vengeance to anyone that dares raise an arm against His Flock. In the second book, Bede leaves behind the martyrdom that suffered the Brits at the hands of the Romans and d eepens into the creation of the modern day Britannica form of beliefs. It seems that as a result of the preceding changes and strength that the martyrs of days before provided the Christian belief in England gave the Church sufficient hold to unite then flourishing Kingdom by respecting religious festivities such as Easter time.It should be noted that by the time that Bede is making reference to evidently St. Agustin (or Agustine to some authors) makes no reference to an Irish saint: Saint Patrick that had sufficient leverage among the clergy of the time. Almost 300 years have passed between the death of Albas martyr and the next evident miracle in Bede’s book, the time when Bishop Mellitus by simple prayers suffocates a fire. Jack 3And thus the man of God, whose mind was inflamed with the fire of Divine charity, and who was wont to drive away the powers of the air by his frequent prayers, from doing harm to himself, or his people, was deservedly allowed to prevail over the w orldly winds and flames, and to obtain that they should not injure him or his. (Bede, Book 2:VII, 114-115) According to Bede it is only through the power of prayer and a meditative life, succumbed to the will, power and guidance of God (through the church) that any person can command any forces of nature and prevent damage, injury or even death.So far Bede has been able to demonstrate the power and benefits of being a truthful Christian to those readers without dabbling into politics. However, by book three, Bede can make a strong statement of this since Chapter I, when he states that a Christian king (Oswald) can restitute the faith of the people in the nation and in his own kingship. One of the most important things to remember when reading this book is that monarchies were believed to be granted by God Himself, thus it was a â€Å"divine right†.Most of Book three is devoted to two main characters: King Oswald who vaguely resembles king Arthur in the importance that he rece ives from this historian as a God following king who, happened to be so saint that even after being slaughtered in battle performed miracles. The other person of importance is Bishop Aidan who was a strong supporter of King Oswald’s piety actions, much like the wizard Merlin in King Arthur’s descriptions; this was a particularly important character in the development of the king’s ruling.Jack 4 However, it seems that when the kingdom lacked of religious stability, the worst circumstances were present: In the above ¬mentioned year of the aforesaid eclipse, which was presently followed by the pestilence, in which also Bishop Colman, being overcome by the unanimous consent of the Catholics, returned home, Deusdedit, the sixth bishop of the church of Canterbury, died on the I4th of July.Erconbert, also, king of Kent, departed this life the same month and day; leaving his kingdom to his son Egbert, (Bede, Book 4:I, 204) It seems interesting that a terrible disease such as pestilence (or plague) might have been deemed common enough not to deserve any of the religious teachings that the book of Bede is full of. There are no prayers that will stop or detain the disease in its tracks, but more over, it refers to mundane affairs such as the setting the affairs in order of a specific archbishop.Despite this, most of the book is full of miracles that happened during the pestilence, people who in their dying beds saw the Glory of Heaven or deaths that were simply â€Å"heavenly† with no pain or misery. Naturally, as the book progresses in dates, other important events happen; such as the assassination of royal heirs, though not in the way that Shakespearian artists would do, but simply stating that anyone who knows the basis of Christianity will deem his or her Jack 5life in little value because the promise of everlasting life would conquer their hearts in a moment. Finally, book five speaks of basically the same things than the other four boo ks, nonetheless, chapter XII has a significant detail: Having stood there a long time in much dread, not knowing what to do, which way to turn, or what end I might expect, on a sudden I heard behind me the noise of a most hideous and wretched lamentation, and at the same time a loud laughing, as of a rude multitude insulting captured enemies.When that noise, growing plainer, came up to me, I observed a gang of evil spirits dragging the howling and lamenting souls of men into the midst of the darkness, whilst they themselves laughed and rejoiced. Among those men, as I could discern, there was one shorn like a clergyman, a layman, and a woman. (Bede, Book 5:XII, 286) The importance of this description is the imagery that it gives, since this description until our days souls in purgatory damnation have been depicted in the same way and even using the same three human elements: The clergyman, the layman and the woman.Nonetheless, the entire chapter portrays a vision quite similar to the one that Dante provides almost 600 years later: An afterlife divided into sections that are populated by those who are â€Å"less than perfect†, â€Å"barely repented† and â€Å"outwardly evil†. Just like Jack 6 Dante, the visionary in Bede’s book five chapter twelve has a guidance that explains things to him so that he might return to life and tell everyone. What is the truth? Well, it is difficult to state it.According to the Bible, Jesus came to earth to create a final covenant, one of the eternal love and forgiveness; nevertheless, the Church had gone out of their way to create an environment of fear and uncertainty. During the time of Bede, it is evident that Church in England used hell and purgatory as means of control and coercion both in social and political atmospheres. Undoubtedly, the use of these â€Å"boogie men† for the society in early Christianity and the first years of medieval era was beneficial providing church and rulers with s ufficient authority to handle and create empires.Would it work nowadays? Yes it will as it has begun to work with the new age belief; the uncertainty of what lies beyond the natural death is something that will present a problem in the human mind; as a result, whatever we can find that will soothe us will become a leverage for those who provide it to us.

Battle of Chattanooga

With the situation worsening, President Lincoln made the Military Division of the Mississippi and placed Major General Ulysses S. Grant in command of all Union armies in the West. Moving quickly, Grant relieved Rosecrans, replacing him with Major General George H. Thomas, and engineer Major General William F. Smith to open a supply line to Chattanooga. After making a successful landing at Browns Landing, west of the city, Smith was able to link up with Thomas and open a supply route in October, which was known as the Cracker Line. On the night of October 28 and 29, Bragg ordered Lieutenant General James Longstreet to sever the Cracker Line. Attacking at Wauhatchie, the Confederate general was very mad. With a way into Chattanooga open, Grant began reinforcing the Union position by sending Major General Joseph Hooker with the XI and XII Corps and then an additional four divisions under Major General William T. Sherman. While Union forces were growing, Bragg reduced his army by sending Longstreets force to Knoxville to attack a Union force that was under Major General Ambrose Burnside. Having consolidated his position, Grant began offensive operations on November 23, by ordering Thomas to go on from the city and take a string of hills near the foot of Missionary Ridge. The next day, Hooker was ordered to take Lookout Mountain. Crossing the Tennessee River, Hookers men found that the Confederates had failed to defend a valley between the river and mountain. Attacking through this opening, Hookers men succeeded in pushing the Confederates off the mountain. As the fighting ended around 3:00 PM, a fog descended on the mountain, which gave the battle the name of The Battle Above the Clouds. To the north of the city, Grant ordered Sherman to attack the north end of Missionary Ridge. Moving across the river, Sherman took what he believed was the north end of the ridge, but was actually Billy Goat Hill. His advance was stopped by Confederates under Major General Patrick Cleburne at Tunnel Hill. He thought that a frontal assault on Missionary Ridge to be suicidal, Grant planned to envelop Braggs line with Hooker attacking the south and Sherman from the north. To defend his position, Bragg had wanted three rows of rifle pits to be dug on Missionary Ridge, with artillery on the very top. Moving out the next day, both attacks met with little success as Shermans men were unable to break Cleburnes line and Hooker was delayed by burned bridges over Chattanooga Creek. As reports of slow progress arrived, Grant began to believe that Bragg was weakening his center to reinforce his sides. To test this, he ordered Thomas to have his men advance and take the first line of Confederate rifle pits on Missionary Ridge. Attacking, the Army of the Cumberland, which for weeks had suffered taunts about the defeat at Chickamauga, succeeded in driving the Confederates from their position. Halting as ordered, the Army of the Cumberland soon found itself taking heavy fire from the other two lines of rifle pits above. Without orders, the men started to move up the hill in order to continue the battle. Though originally mad at what he perceived to be a neglect for his orders, Grant moved to have the attack supported. On the ridge, Thomas men advanced steadily, aided by the fact that Braggs engineers had accidentally placed the artillery on the actual crest of the ridge, rather than the military crest. This mistake stopped the guns from being brought to bear on the attackers. In one of the wars most dramatic events, the Union soldiers surged up the hill, broke Braggs center, and put the Army of Tennessee to rout. This battle finally ended in a Union win, which they were of course happy about, but even happier because of their loss at Chickamauga, so this win made them feel like it made up for their other loss. The victory at Chattanooga cost the Union 753 men that were killed, 4,7220 of the men in their troops were injured and 349 missing. The Confederate’s casualties were listed as 361 killed, 2,160 wounded, and 4,146 captured and missing. The Battle of Chattanooga opened the door for the invasion of the Deep South and the capture of Atlanta in 1864. In addition, the battle destroyed the Army of Tennessee and forced Confederate President Jefferson Davis to relieve Bragg and replace him General Joseph E. Johnston. Following the battle, Bragg’s men went back south to Dalton, GA. Hooker was sent out to pursue the broken army, but was defeated by Cleburne at the Battle of Riggold Gap on November 27, 1863. The Battle of Chattanooga was the last time Grant fought in the West as he moved East to deal with Confederate General Robert E. Lee the following spring. ?

MSc Practical UNIX Security ''LDAP'' - Essay Example The Light Weight Directory Access Protocol is a communication standard that provides a communication channel for the clients within a directory service. A comprehensive definition of LDAP is defined as â€Å"Lightweight Directory Access Protocol, a protocol which helps find people, computers and other resources on a network. Designed to work with existing address-book standards and improve compatibility between widely differing systems, the ldap standard was adopted by the ietf in 1997 and now forms the basis of many white-page directories on the web. It has also been incorporated directly into some software programs and operating systems, making it possible to find e-mail addresses without visiting a directory site† (Ldap. 2003). LDAP was established after X.500 protocol, which was also a directory service standard protocol. ... Active directory is â€Å"an implementation of LDAP directory services by Microsoft for use in Windows environments. Active Directory allows administrators to assign enterprise-wide policies, deploy programs to many computers, and apply critical updates to an entire organization. An Active Directory stores information and settings relating to an organization in a central, organized, accessible database. Active Directory networks can vary from a small installation with a few hundred objects, to a large installation with millions of objects† (Active Directory. 2007). Few checklists are applicable including the network connectivity testing and raising the Active directory domain functional level to Windows 2003. Moreover, for Linux / UNIX, ‘identity management module’ installation is required on the domain controller along with the configuration of NIS server. LDAP Account Management In order to manage account in the UNIX network environment, the Unix systems are con figured with Microsoft Active directory for centralized management of user accounts. Moreover, it also solidify network security by integrating role based access and Kereberized authentication. Consequently, the operational cost is minimized, for the management of UNIX accounts. Moreover, UNIX contains various features for authentication and authorization.

Roles of a Global Manager - Essay Example According to the Soviet-Belgian joint venture agreement, Wane Machines was supposed to send three experienced executives for the key managerial positions -– to serve as Rus Wayne’s deputy general manager, manufacturing manager, and financial manager for the first two or three years. After that, the Russians would take over the positions. The major objectives of this policy were to provide "assistance in technology and management skills transfer, management systems and processes development, and local personnel coaching." While the obstacles and the issues that came up in staffing were basically due to cultural differences, not all the issues arising out of culture difference would be handled here. This report focuses on the inefficiencies in cross-cultural communication that impacted the smooth functioning of this joint venture. The Soviet law insists that local managers should be in charge as they are most knowledgeable and capable of handling local situations although they do not insist that Soviet citizens should hold the senior-most position. Local nationals were taken in the positions of sales and service managers and human resources manager from the beginning as the knowledge of local and employment practices helps in overcoming these obstacles. These decisions were not implemented. The general manager could not send the three expatriates to Russia as per agreement nor was an HR manager appointed on schedule. The general manager wanted to play the role of HR manager as well. The deputy general manager, an American, sent to Russia had no experience of working in Russia but accepted the job because of career move. The manufacturing manager was from France and his interest in Russia was purely career development. The financial manager, an Englishman sent to Russia had merely 2 years of experience at Wane and hence they provided him training for 6 months before sending him to Russia.
