20 Synonyms for Expert

20 Synonyms for Expert 20 Synonyms for â€Å"Expert† 20 Synonyms for â€Å"Expert† By Mark Nichol Just as the many synonyms for beginner should be picked over with care to capture the correct connotation, the numerous alternatives available for referring to an expert have sometimes unique or specific senses appropriate for some contexts and unsuitable for others. Here’s a usage guide to such words: 1. Ace (ultimately derived from the Latin word as, â€Å"one,† â€Å"unit†): Originally, a combat pilot with at least five (later, ten) confirmed kills, or enemy planes shot down, and by extension a highly skilled person. The slang designation stems from the most valuable card in a deck and far predates powered flight; it was used to denote excellence, and eventually â€Å"top of the deck† athletes were so designated. The term is still employed in sports, as in gaining a point on a serve in tennis or hitting a hole in one in golf, as well as in the scholastic sense of performing well in a course or on a test. 2. Adept (from the Latin word adeptus, â€Å"having reached, attained†): Usually has the connotation of a mystical or secret pursuit or body of knowledge; this sense stems from the use of the term in Middle English to refer to an alchemist, and the term is widely used in heroic-fantasy literature featuring wizards and sorcerers and in writing about mysticism, though it is appropriate for general usage. 3-4. Artist (ultimately from the Latin word ars): Originally referred solely to a practitioner of art, but now often applied to someone who demonstrates skill with an artistic flourish in any pursuit. The French form, artiste, is used only facetiously or by or in reference to the pretentious. 5. Authority (from the Latin word auctoritatem, â€Å"advice, opinion†): Connotes the go-to source for, well, authoritative information or advice, or the governing agency or institution for a body of knowledge. As you may have guessed, the Latin term from which this word derives is also the source of author. 6-7. Connoisseur (from the Latin word cognoscere, â€Å"to know†): Usually employed in gustatory or artistic contexts, identifying someone with a refined taste in wine, for example, or a specific school of painting. The term, which comes to English from French, has an Italian cognate, cognoscente, which, when borrowed into English, has the same sense or that of â€Å"one in the know.† (The plural is cognoscenti.) 8-9. Doyen (from the Middle French word meaning â€Å"leader of ten,† stemming from the Latin term decanus, and ultimately from the Greek term dekanos, both with the same meaning): Carries a connotation similar to that of connoisseur or maven, of a person with knowledge about or skill in a rarified topic or area. Dean, sometimes used to denote an expert in or master of a specific field as well as in its academic sense, derives from doyen. 10. Guru (from the Hindi word for â€Å"teacher† or â€Å"priest,† from the Sanskrit term guru-s): Originally denoted a spiritual mentor, but the meaning was later extended to a secular sense and then generally to an expert. 11. Hotshot: Originally referred to a headstrong person or a headlong object; it now is usually employed in the sarcastically derogatory sense of someone who considers themselves more knowledgeable or capable than they are. 12. Initiate (from the Latin word initium, â€Å"beginning†): Originally, this word identified one who had undergone or was about to undergo an initiation ceremony, but now it is also a designation for one privy to certain knowledge or skills. 13-14. Maestro (from the Italian word for â€Å"master,† ultimately from the Latin term magister): A term for a gifted composer, later extended to orchestra conductors and now sometimes used facetiously to refer to those with pretensions of genius. The English form master denotes both an academic leader (hence â€Å"master of arts† and so on) and one who is eminent in any given field of endeavor. 15. Maven (from the Yiddish word, meyvn, â€Å"one who understands,† ultimately from the Hebrew term mebhin): Generally used in the sense of someone with expertise in a sophisticated area of study or skill. 16. Pundit (from the Hindi payndita, â€Å"learned man,† ultimately from Sanskrit payndita-s): Usually employed to refer to commentators, analysts, or consultants, often with a negative sense because of the widespread realization that one can find â€Å"experts† who will support or attack any position one favors or opposes. 17. Scholar (from the Latin word schola, â€Å"school,† ultimately from the Greek term skhole): Originally, referred to a student, but now, except in formal or jocular contexts, denotes an academician. 18. Virtuoso (from the noun form of the Italian word meaning â€Å"skilled, learned,† from the Latin term virtuosus, â€Å"virtuous†): Originally applied to highly talented musicians, but now appropriated in many other contexts to refer to manual or mental dexterity. 19-20. Wizard (from Middle English wys, â€Å"wise,† and -ard, â€Å"one who [is]†): The supposedly traditional connotation, that of a person with magical powers, supplanted the original meaning of â€Å"wise man,† and the modern sense, outside of fantasy-literature and computer-gaming circles, is of someone astonishingly good at a certain endeavor. Whiz is either a short form of wizard or a variant of the onomatopoeic whizz, â€Å"humming, hissing sound or movement.† Want to improve your English in five minutes a day?

The construct of the western democratic moral.

The construct of the western democratic moral. BackgroundThis briefing paper will focus on the works of Stephen Lukes, Susan Wolf, and Sir I. Berln to examine their arguments on moral conflict. Therefore for Lukes, moral conflict can not be separated from making sense of them as it could be due to ignorance or error of the social pathology . While, Wolf argues that the plurality of values or principles that are relevant to moral judgment are grounded in either relativism or subjectivism or a combination of both . She further questions whether pluralism is actually an appropriate paradigm for dealing with moral conflicts, given that some conflicts just can be resolved within the paradigm, such as Indigenous claims for real justice for the stolen generations. Similarly, Berln argues that for moral conflict to be just it should be premised on the sacrifice of individuals for the freedom of society . Therefore each academic is able to facilitate a debate about moral conflict by focuses on either the power behind the moral conflict, t he individual and community thought processes and natural rights discourse.Wolf!These methodologies highlight that moral disagreement is inevitable in western societies as the multitude of beliefs and values results in injustice.Stephen LukesFor Lukes there is no real moral conflict, only 'merely apparent conflict - of ignorance or error, or of individual or social pathology' . Therefore his article 'Making Sense of moral conflict' gives an account of moral disagreement that shows that it is constructed by individuals through lack of experience and feelings with the issue at hand. Moreover, Lukes believes that utilitarian principles win out over any other when sorting out moral disagreements on a large or visible political scale. Furthermore, Lukes criticises relativist arguments by declaring that relativism fails to take claims seriously by denying their applicability beyond cultural...

Strategic bussiness Essay Example | Topics and Well Written Essays - 5000 words

Strategic bussiness - Essay Example The critical attributes of specifying task objectives are determined by various factors. In the first place, an organisation embarks on undertaking a specific project or task as a result of the need to fulfill certain objectives anticipated from the successful completion of the desired task. Indeed, there is need to keep in mind the main reason why an organisation has decided to undertake that task. During the contemporary period, organisations are in existence for various reasons and they seek to fulfill different objectives. As a result of the fact that organisations operate in a dynamic environment, they often find themselves confronted by situations which require them to change their usual way of conducting business. Against this background, the attributes of specifying the organisation’s attributes are mainly influenced by its core business and core competences. It follows from the argument that an organisation can only embark on initiating change when there are possible or foreseen benefits that can be enjoyed after the successful completion of the project. It is therefore very important for the organisation to consider its core competencies and the likely benefits which can be brought by the envisaged change. Another attribute includes the need to determine if the task is attainable. In some cases organisations may decide to embark on specific tasks as a way of trying to waiver negative impacts that may affect their operations but this may be suicidal if the set goals are difficult to attain. Whilst it may sound easy to embark on a particular project, it is also very important to ensure that the organisation has the requisite resources to achieve the objectives set. Broadly speaking, the resources range from human resources, financial resources as well as time. Failure to take this into consideration may negatively impact on the envisaged task. Resource management is primarily concerned with mapping out the allocation of the resources, identifying

Main Messages Conveyed to the Indians by Clarks Address Essay - 2

Main Messages Conveyed to the Indians by Clarks Address - Essay Example It is evidently clear from the discussion that the language Clark uses in addressing the Indians is significant. He refers to them as â€Å"children†. This was done to establish a position of authority over them. He indicates that the Great Chief would take care of them, just like a father would care for his child, but only if they are obedient to the Great Chief. In modern times, this type of speech would be considered very demeaning if directed from one culture to another. In defense of Clark, he probably was mimicking the type of speech he thought the Indians would understand and react to in a positive manner. The researcher states that some of the Indians probably did react in a positive way to Clark’s message. The lure of more luxury items and better housing would have been a great incentive for some Indians. But other Indians would have been resistant to the message. Not all Indian cultures were the same. Some place a greater value on acts of bravery and warfare t han on having luxury items. They would have probably rejected the offer to visit with the Great Chief. President Jackson justifies the removal of the Cherokee Nation to the lands west of the Mississippi River in several ways. He argues that this removal will be good for the United States and the Cherokee Nation. It will be good for the Cherokee Nation because it will allow them to be free of the control of the states. They will be removed to lands that they can inhabit and call their own. They will be able to run their own governments, practice their own traditional religion and preserve their culture from destruction by the white man. He also argues that the Indians will benefit because the government is going to pay for the entire cost of their resettlement. He goes on to state that through philanthropy, the United States had attempted to help their tribes, but they would not respond to the help.

The TED Assignment Research Paper Example | Topics and Well Written Essays - 1500 words

The TED Assignment - Research Paper Example In this essay I will discuss a few of the videos and how they believe one should lead their lives. The first video I saw was by Amy Purdy who lost her legs due to bacterial meningitis. At that time, she was devastated and wondered how she was going to fulfil her dream of traveling the world and of snowboarding. But then she realized that she had an option to take her life in the direction she wanted to take. So she accepted the fact that she doesn’t have real legs anymore and will have to bear with the artificial ones. She imagined herself to keep walking, helping people and snowboarding again. And this is the life she chose. She became creative about the artificial legs and customized them according to her needs. She failed, slipped, fell many times, but she would not let go of hope that easily. This was when she understood one of the most important life’s lessons: Obstacles do only two things to you-make you stop or force you to be creative. (Purdy, 2011) Her story tells you that one has two options when faced by a real tragedy: you can whine, be depressed, let go of hope and life or look right into the eyes of the world and follow your dreams irrespective of how many obstacles lay in front of you. These obstacles might stop you from doing something the way normally people do, but they also help you to imagine and discover new ways of following your dreams, living life to the fullest and being happy. Another speaker at Ted, Shawn Achor, a researcher and teacher of positive psychology talks about the formula of happiness. He argues that we always talk about what average people think, believe and do. We research on people and we generalize them as average people. He believes that â€Å"if we study what is merely average, we will remain average†. Furthermore he talks about the general perception of life and happiness. He argues that our happiness is mostly characterized by

Risperidone for Methamphetamine Induced Psychotic Disorder

Risperidone for Methamphetamine Induced Psychotic Disorder On the efficacy of risperidone for the treatment of methamphetamine induced psychotic disorder, a dose ranging study Induced psychosis, diagnosis and treatment Worldwide growing methamphetamine abuse is one of the most serious health problems with several different consequences for victims, especially in developing countries. Chronic methamphetamine abuse is associated with several psychiatric problems in all countries which are faced to epidemic methamphetamine abuse. Methamphetamine induced psychosis (MIP) is a major medical challenge for clinical practitioner from both diagnostic and therapeutic viewpoints. Stimulant psychosis commonly occurs in people who abuse stimulants, but it also occurs in some patients taking therapeutic doses of stimulant drugs under medical supervision. The main characteristic of meth psychosis is the presence of prominent hallucinations and delusions. Other drugs, such as cocaine and marijuana, can trigger the onset of psychosis in someone who is already at increased risk because they have vulnerability. The current literature review attends to explain several aspects of MIP, including epidemiologically, clinically and investigators proposed pharmacologically treatment based on recently published data. Introduction Amphetamine and methamphetamine have the most substances for abuse among the synthetic psychostimulant across the world1. The overall the prevalence of methamphetamine users (excluding amphetamine users) ranges from 10.5 to 28.5 million people worldwide (0.2% to 0.6% of adults between 15 to 64 years old)2. Accompanied to amphetamine these synthetic psychostimulants are ranked as the 2nd abuser illicit drugs after cannabis as the 1st and before cocaine and opiates1. Many consequences follow methamphetamine abusers including medical, psychiatric, cognitive, legal and socioeconomic problems. It is unclear why methamphetamine abusers are more involved with legal consequences than all other illicit drug abusers3. It might be due to more psychotic symptoms induced by these psychostimulant drugs, or flaring of symptoms in a subtle or stable schizophrenia which could be exacerbated by methamphetamine4. It has been well known that such drugs are able to produce psychotic symptoms in persons with no history of previous psychiatric disorders.5,6 Epidemiology and clinical manifestations of MIP There are other substances able to produce psychosis including cocaine, cannabis, alcohol, hallucinogens, heroin and sedatives7.There will be a diagnostic challenge to meet a net diagnosis for drug-induced psychosis, if the clinical practitioner cannot establish the presence of psychotic symptoms before initiating drug abuse. In a survey, among 400 cases who admitted in different psychiatric emergency departments for their psychotic symptoms, 44% received a substance-induced psychosis diagnosis and 56% were diagnosed essential psychosis8. According to DSM-IV criteria, diagnosis of primary psychosis is usually after at least 4 weeks with persisting symptoms without heavy substance use. In addition to the previous history of substance abuse, other factors lead to drug-induced psychosis including parental substance abuse, dependency to drug (rather than occasional abuse) and visual hallucination. Lower positive and negative syndrome scale with th positive history of drug abuse put in fa vor of drug-induced psychosis, as well as more consciousness to psychotic symptoms and more tendency to suicidal thoughts are another feature of drug-induced psychosis. Generally, reported psychotic symptoms due to MethAmphetamine(MA) abuse, from USA, Japan, Taiwan, Australia and Iran are the same as each other including (as studied by Fasihpour et al) persecutory delusions (82%), auditory hallucination (70.3%), reference delusion (57.7%), visual hallucination (44.1%), grandiosity delusion (39.6%) and jealousy delusion (26.1%)9. Although certain risk factors could not be extracted among documented literature and many conducted studies by different authors in involved countries have been reported more common factors include: 1. Pyschosis induction is largely dose-dependent than duration-dependent5,10,11 2. Positive family history of psychotic symptoms especially in first degree relatives5. Interestingly protracted and more resistant psychosis was occurred in abuser persons, whose one of their first degree relatives has been involved by schizophrenia12.3. Presence of premorbidity in abuser subjects, such as schizoid/schizotypal personality traits, alcohol dependency, antisocial personality disorders and major depression, all can be psychosis induced by methamphetamine5. 4. History of sexual abuse experience, recent higher occasion of MethAmphetamine(MA) abuse plus another illicit substance13. 5. Childhood Attention Deficit Hyperactive Disorder (ADHD) may be associated frequently with psychosis reports14. 6. Hi gher serum level of methamphetamine and amphetamine are associated with more profound psychotic symptoms4. The route of consumption (oral, smoking, injection) was not a significant factor in Mc Keit et al study6. But according to Matsumoto et al. smoker abuser show more quickly acute psychotic symptoms than who use the injection, because smokers have poor control on MA consumption. In addition psychotic syndromes in injection abusers require more medical care to respond to treatment15. Other personal characteristics such as age at which abuse is started, education, IQ, and duration of methamphetamine use were not associated significantly with risk of psychosis developing among abusers8. Female preponderance for undergoing psychotic symptoms was established among participant persons in the study of Mahoney and his coleagues16. It is noticeable to mention that the results of studies on MIP characteristics are somewhat inconsistent because of different cultural population, different accuracy in methods of studies and so on. But they provide a general opinion for further investigations and more accurate and localized studies. Sign and symptoms of MIP Reported psychotic symptoms among several different studies performed in Japan17, Taiwan5, Australia6, Tailand18 and Iran9 all are unanimous in obtained results. The most common features include persecutory delusion and auditory hallucination followed by delusion of reference, visual hallucination and thought broadcasting. MIP is initiated with excitation and increased focusing or concentration states, following by prepsychotic states and delusions which may subsequently progress to overt psychosis with positive symptoms10. The onset of first psychotic episode from the first occasion of methamphetamine consumption ranges from 1.7 years in smoker abusers to 4.4 years in injectioners19 and or 5.2 years without considering route of abuse10. Individuals with intense eagerness20, injection of methamphetamine and methamphetamine abusers are at higher risk for experiencing more severe psychosis21. Although MIP usually have short courses duration but longer and persistent episodes of psychos is have been reported even after discontinuation of drug abuse and in abstinence period17. As protracted MIP frequently occurred in many studies, it remains unclear whether methamphetamine can produce a chronic psychotic disorder or methamphetamine has uncovered a psychotic disorder in a patient with psychotic background5. The risk factors for developing long lasting MIP include positive family history of first degree relative involved to schizophrenia, premorbidity with a personality disorder specially schizoid/schizotypal form, a former neurological disorder like ADHD, head injury and learning disability2. During the abstinent period, MIP relapse might occur in a previously undergone short MIP, as well as any stressor like insomnia and severe alcohol intake.10,23,24 Methamphetamine and not stress induced MIP relapse occur with a likelihood of 60% to 80% in less than 1week to 1 month respectively, after re-exposure to MA8. A history of more than 2 years MA abuse makes the person susceptible for spontaneous relapse of psychosis without any methamphetamine reabusing for years.10 MIP Treatment pharmacological approaches Although no medical agent(s) are approved as therapeutic drug for MIP yet, due to a few numbers of pharmacological evaluations which have been proformed for finding a suitable choice in recent years. According to bio-molecular neurotransmitters influenced by MA, several pharmacologic agents are proposed for treating MA with clinical implications such as dependency and MIP. In this review a brief will run to introduce involved pharmacological groups separately. Dopaminergic agents Modafinil is a dopaminergic agonist approved essentially for sleep disorders such as narcolepsy, obstructive sleep apnoea/hypopnoea and idiopathic hypersomnia. Modafinil may increase efficacy of cognitive behavioral treatments and decrease craving in methamphetamine dependency25. It may have beneficial effect in schizophrenia and thereby in MIP.26,27 Bupropion, a re-uptake inhibitor of dopamine has demonstrated its effect as decreasing methamphetamine use specially in low to moderated dependency.28,29,30 Methylphenidate (Ritaline) and Dextroamphethamine (d-amphethamine) both increase releasing of dopamine in synaptic cleft and have high capacity to be abused. They show strong efficacy in studies to stop or reduce MA abuse in even deep dependency.31-34 Although the above quoted drugs have not revealed any direct effect for MIP, but it seems that appetite decreasing for MA use occur by these drugs, which can be indirectly effective for managing MIP as well. Aripiperazole, a dopamine D2-receptore partial agonist and a second generation antidepressant is proposed for MethAmphetamine(MA) dependency and MIP. In a study driven by Sulaiman et al. Aripiperazole was effective for diminishing the severity of psychosis resulted from methamphetamine, but it was failed to increase abstinence duration.35 In another study, Farnia et al. compared the efficacy of aripiperazole versus risperidone in MIP cases, in a double blind randomised control trial. After six weeks trial with aripiperazole 15mg/day or risperidone 4mg/day, they concluded that both drugs are able to significantly decrease the MIP severity, however rispridone causes showed more reduction on positive symptoms while aripiperazole was more effective on negative symptoms.36 The ability of antipsychotics like aripiperazole and haloperidol in suppressing the dopamine releasing in amygdala of animal experiments which caused marked reduction in behavioral sensitivity following MA exposure, may explain its benefits on MIP.37 In another animal model study, it was shown by Futamara et al. that aripiperazole can diminish behavioral sensitization through acting on 5-HT1A receptor.38 Risperidone is evaluated solely for its ability to prolong abstinent period in 4 weeks administration of 3.6mg/day in an open-label trying. Results demonstrate a decrease in meth consumption in abusers.39 Two separate case reports have considered the dramatic response of MIP to risperidone therapy.40,41 Despite safety applications of classic antipsychotics Hatzipetros et al. warned about an unknown toxic effect of conventional antipsychotics like administrating the haloperidol to GABAergic cells in subchronic treatment of MIP might lead to hyperkinetic movement disorder and convulsion42. Other antipsychotics like quetiapine and olanzepine were applied successfully for drug– induced psychosis.43,44 GABAergic agents Several different GABA agents like baclofen45,gabapantine45,46, vigabatrine47,48, topiramate49 and benzodiazepines were proposed for treatment of MA dependency and associated psychosis based on their effects on decreasing the dopamine transmission in mesolymbic system by which reinforcing effects of MA is reduced.50,51 But ,actually conducted trial studies are somewhat inconsistent to suggest a precise recommendation.49,52 Nevertheless Ito K et al. showed that clonazepam in animal model experiments did not obtain explicating of behavioral sensitization in rats which were under treatment with MA.53 Serotonergic agents No pharmacological trial studies lead to any clinical recommendation of serotonergic agents for MIP found in web published searching except for two animal experiments in which the role of serotonergic receptors are evaluated in locomotor activating and developing behavioral sensitization. Kaneko et al. studied the inhibitory effect of fluoxetine and paroxetin, 2 clinically available SSRI agents, on establishing and expression of MA induced behavioral sensitization and suggested a prophylactic role of SSRIs for preventing of psychotic states like hallucination and paranoid symptoms due to methamphetamine abuse.54 Ago et al. demonstrated the critical role of serotonine system in behavioral sensitization formation in mice by osemozotan a 5-HT1A-receptor agonist and ritanserin a 5-HT2-receptore antagonist and again suggested a capacity of serotonergic agents for treating methamphetamine psychosis.55 Opioid antagonist Naltrexone, a pure antagonist of morphine have showed successful outcomes in MA dependency management by decreasing craving, probably because of endogenous opioid system modulating role in reducing of reinforcing effects of metamphetamine.56-61 Behavioral sensitization produced by frequently exposure to methamphetamine is prevented by induction and expression of naltrexone in mice.62 But naltrexone plus N-acetylsysteine, an antioxidant, fail to demonstrate priority to placebo group for MA dependency treatment.63 Although no particular study with emphasis on the effects of naltrexone on MA-induced psychosis was found, it may be associated with precise changes in severity and prevalence of MIP because of its strong effects on abolishing dependency. Other unclassified treatment Minocycline, a second generation antibiotic was proposed for MIP treatment. In two separate case reports minocycline administration were associated with significant results in curing the psychotic symptoms of methamphetamine abuse probably due to its anti-inflammatory effects on micoglia.64,65 Electroconvulsive therapy (ECT) is mentioned for its high capacity to create a dramatic response in a MIP cases whose psychotic symptoms were resistant to conventional pharmacological antipsychotic therapy.66 Discussion Methamphetamine abuse is now going to become an epidemic problem in many countries. Chronic MA abuser underwent many medical psychiatric cognitive and legal consequences. One of the most important complications is the psychosis. Many studies were performed and a plenty of pharmacological drugs were proposed for managing of MA dependency, although none of them were approved yet, but only a few investigations tried to find drugs targeted on psychosis due to MA. These drugs as reviewed in this articles belongs to different biochemical neurotransmitters like dopaminergic antipsychotics, serotonergic agents and GABAergic drugs. All the studied drugs failed to obtain approval validity, although according to the results of conducted studies merely all of these agents could subside the MA associated psychosis. Recognizing neurotransmitter/receptor systems involved and influenced by MA in animal models and human experiments that can elevate knowledge about developing MA-induced psychiatric sy ndromes, especially psychosis, is the best way to overcome MIP pharmacologically and is recommended strongly for future studies.
