History of Cocaine Use Medical and Recreational Uses

History of Cocaine Use Medical and Recreational Uses Cocaine through the ages: from elixir to poison. Abstract: Cocaine, a plant alkaloid derived from coca leaves is a potent stimulant of CNS and has local anesthetic action as well. Historically, it was ingested in the form of chewing coca leaves, to suppress hunger and fatigue. With discovery of its local anesthetic properties, cocaine was introduced into world of medicine and a local anesthetic, but over last few decades, gained popularity as drug of abuse. Cocaine carries with it great potential for addiction and abuse. It is administered through various routes, smoking free-base crack and intranasal inhalation being most popular. Its primarily metabolized in liver and distributed to all body tissues. Due to lipid nature it tends to concentrate in brain and adipose tissues with chronic administration. Its mainly eliminated through kidneys, but saliva and stools are also routes of excretion. A number of health hazards have been shown to be associated with cocaine use including, cardiac abnormalities, psychological disturbances, addiction pot ential and renal failure with or without rhabdomyolysis. Acute and chronic cocaine toxicities with sufficient collected data are included. Techniques for detecting cocaine in blood including enzyme linked immunoassay and POCT (Point of care screening tests) have also been discussed. An analysis of recent trends in cocaine uses have been studied and presented along with graphical illustrations of epidemiological evidence to support the data. Introduction and objective: Objective: to display how cocaine has evolved through time in its uses and available forms, from simple coca leaf chewing custom of South Americans in 2500 BC to modern forms of freebase-coke among others as one of the most commonly abused toxic drug. Methodology: Data was mainly collected from electronic resources, but text on immunology and pharmacology was also consulted. From electronic sources, I mainly used search engines using a number of keywords including ; history of cocaine, crack, pharmacokinetics of cocaine, mode of action , coca leaf, acute cocaine poisoning, chronic cocaine toxicity, Karl Koller, Sigmund Freud, Immunoassay, etc. I also went through a number of journals available online, and a number of researches conducted which related to cocaine. My aim was to find changes in cocaine use from its discovery to date, and show, with help of collected data, that it has moved in a negative direction. Brief history: Cocaine, use of which, according to some sources, date back to at least 1200 years, has now, rightfully, earned itself a place in drugs of abuse list among others like Caffeine, Nicotine, Amphetamine, etc. To date, cocaines uses have evolved from gaining popularity as topical anesthetic agent, and as component of energizing drinks to becoming one of the most abused drugs in the world. It is a powerfully addictive stimulant drug, which acts by interfering with cerebral and peripheral synaptic transmission among neurons. Mode of action has been described in greater detail later in pharmacodynamics section, but for brief introduction, it interferes with reuptake of, and thereby enhance duration of action of, monoamines, dopamine, serotonin and nor epinephrine Brain PF et.al (1989). It also produces membrane stabilizing effect, more commonly referred to as local anesthetic effect. Latter is achieved through modulation of voltage gated sodium channels and consequent blockade of sensory im pulses conduction from that part of the neuron to central nervous system. Brain PF et.al (1989) Earliest records of cocaine use reveal it to be a part of South American custom of chewing coca leaves. This use is believed to date back to 2500BC. Steven Cohen (1981) Practice of chewing mixture of tobacco and coca leaves was defined by Nicolà ¡s Monardes, in 1569, to induce â€Å"great contentment†. Cocaine is the active component of coca leaves, which also contains nicotine. Karch SB (1998). In 1859, Italian doctor, Paulo Montegazza, after witnessing coca use by natives of Peru, and getting mesmerized by it, decided to study the effects of cocaine on himself. After his studies he concluded his findings into a paper in which he declared cocaine to be medically useful in treating furred tongue in the morning, flatulence and whitening the teeth. Steven R. King (1992). In 1863, French chemist, Angelo Mariani, introduced popular cocavine, Vin Mariani. Vin Mariani wasproduced from mixture of 6 mg coca leaves per fluid ounce of Bordeaux wine. Courtwright DT (2001) Angelo Mariani, creator of Vin Mariani, which later became the hallmark of cocavines was honored with Vatican gold medal by Pope Leo XIII for this achievement. Ethanol, a component of vin mariani, is believed to extract cocaine from coca leaves. In 1884, the concept of cocavine was adopted by John S. Pemberton, with introduction of Pembertons French Wine Coca. After prohibitions imposed on cocaine use and manufacture of cocaine-containing products including cocavine in 1885, Pemberton introduced carbonated, non-alcoholic form of Vin Mariani and called it Coca-cola. Richard Ashley (1975). From 1906 onwards, however, after Pure Food and Drug act was passed, decocainised forms of coca were used for manufacture of coca-cola. In 1884, Austrian physician Sigmund Freud, recommended cocaine for treatment of morphine and alcohol addiction. A strategy that was later employed in 1879 when cocaine was used to treat morphine addiction. Steven Cohen (1981). In his published word, ÃÅ"ber Coca, Sigmund defined effects of cocaine in following words: â€Å"exhilaration and lasting euphoria, which in no way differs from the normal euphoria of the healthy personYou perceive an increase of self-control and possess more vitality and capacity for work.In other words, you are simply normal, and it is soon hard to believe you are under the influence of any drug.Long intensive physical work is performed without any fatigueThis result is enjoyed without any of the unpleasant after-effects that follow exhilaration brought about by alcohol.Absolutely no craving for the further use of cocaine appears after the first, or even after repeated taking of the drug† In 1985, use of cocaine for induction of spinal anesthesia was accidentally discovered by American neurologist Leonard Corning while he studying the effects of cocaine on spinal nerves in a dog and accidentally pierced the dura matter. Corning JL (1885) Cocaine was, however, not used as anesthetic in spinal surgery until 1989 when first planned cocaine induced spinal anesthesia was administered in a surgery, by August Bier. A. Bier, (1899) Coca leaves have traditionally been used as suppressants for fatigue, thirst, and hunger. Its use has now been limited to Andean countries, where coca leaf chewing and coca tea consumption are still practiced. Industrially, coca leaves serve as source of drug cocaine, and in some cosmetic and food industries, including coca cola. Richard Ashley (1975) From 1980s to date, cocaine has gained popularity as drug of abuse, and has widely replaced heroin and other narcotics as drug of abuse, being used in different forms and administered via various routes. Richard Ashley (1975) Discovery: Discovery of cocaine, as local anesthetic, is claim to fame for Austrian ophthalmologist, Karl Koller. Kollers name is credited with demonstration of anesthetic effect of cocaine, in 1884. Karl Koller was a close associate of Sigmund Freud who in same year recommended cocaine to be employed in treatment for morphine and alcohol addiction. Hruby K (1986). Koller studied effects of cocaine on eye by applying the drug to his own eye and later pricking it with pins. He presented his findings to the Heidelberg Ophthalmological Society in same year. Hruby K (1986) After successfully experimenting on himself, Koller used cocaine as local anesthetic in eye surgeries, a use that continues to this day. Cocaine was later employed in other fields including dentistry for induction of local anesthesia, Today, however, cocaine has largely been replaced by other local anesthetic agents like lidocaine, xylocaine, bupivacaine, etc, which produce local anesthetic effect as efficiently and do not carry potential for abuse.Hruby K (1986) Isolation: Friedrich Gaedcke, aGerman chemist, was first person to successfully isolate cocaine from coca leaves, in 1855. An improved isolation process was, however, developed by Albert Niemann, who was enrolled as a Ph.D. student at a German university, University of Gottingen , in 1859. Niemann wrote a dissertation describing steps of isolation which was published in 1860 and was entitled, â€Å" ÃÅ"ber eine neue organische Base in den Cocablà ¤ttern† (On a New Organic Base in the Coca Leaves). F. Gaedcke (1855) Formal Chemical Name (IUPAC) for cocaine: (1R,5S)-methyl 8-methyl-3-(phenylcarbonyloxy)-8-azabicyclo[3.2.1]octane-2-carboxylate. Chemical structure of cocaine: Structure of cocaine molecule was first defined by Richard Willstà ¤tter in 1898. Medicalisation and popularization: Ever since its discovery, cocaines medical uses were quickly exploited through research and experimentation. Spanish physicians described first medical uses of cocaine as early as 1596, but the use of cocaine did not become more widespread until 1859, when Albert Niemann isolated the drug from coca leaves. Soon after it was isolated, cocaine was used to try to cure almost all the illnesses and maladies that were known to man. (Albert Niemann 1860) 1859s Montagezzis discovery about cocaine being useful in treating furred tongue in the morning, flatulence and whitening the teeth, was one of the earliest recorded studies that signified possible medical importance of cocaine. In 1879, Vassili von Anrep, of the University of Wà ¼rzburg, demonstrated analgesic properties of cocaine in an experiment that he conducted on a frog. He prepared two separate jars, one containing cocaine-salt solution, other containing salt water serving as control. One of frogs legs was submerged in cocaine solution and other in control followed by stimulation of leg in different ways. Reactions in two legs varied considerably. In the same year, cocaine began to be used in treatment of morphine addiction. The commercial production of purified cocaine gained momentum only in the mid-1880s. Its greatest medical value was in ophthalmology. Eye-surgery stood in desperate need of a good local anesthetic. This was because in eye operations it is often essential for a conscious patient to move his eye as directed by the surgeon without flinching. Karl Kollers demonstration of anesthetic properties of cocaine in 1884 was an important breakthrough establishing cocaines importance, medically when it was introduced in Germany as local anesthetic for eye surgery. (Altman Aj et.al 1985) Kollers discovery was later followed in 1985 by Leonard Cornings accidental demonstration of cocaines use in induction of spinal anesthesia, which became formally employed in spinal surgery in 1989 when first planned cocaine induced spinal anesthesia was administered by August Bier. Medical use of cocaine has largely been restricted to induction of local anesthesia. Even as local anesthetic agent, discovery of hazardous effects of cocaine use led to early development of safer alternative drugs like lidocaine, etc. One of its first non medical uses of cocaine was in military. In 1883 Theodor Aschenbrandt administered cocaine to members of the Bavarian army. It was found that the drug enhanced their endurance on maneuver. His positive findings were published in a German medical journal, which brought the effects of this wonder drug to a wider medical audience, including Sigmund Freud. Following is taken from â€Å"On cocaine† by Sigmund Freud. â€Å"A few minutes after taking cocaine, one experiences a certain exhilaration and feeling of lightness. One feels a certain furriness on the lips and palate, followed by a feeling of warmth in the same areas; if one now drinks cold water, it feels warm on the lips and cold in the throat. One other occasions the predominant feeling is a rather pleasant coolness in the mouth and throat. During this first trial I experienced a short period of toxic effects, which did not recur in subsequent experiments. Breathing became slower and deeper and I felt tired and sleepy; I yawned frequently and felt somewhat dull. After a few minutes the actual cocaine euphoria began, introduced by repeated cooling eructation. Immediately after taking the cocaine I noticed a slight slackening of the pulse and later a moderate increase. I have observed the same physical signs of the effect of cocaine in others, mostly people my own age. The most constant symptom proved to be the repeated cooling eructation. This is often accompanied by a rumbling which must originate from high up in the intestine; two of the people I observed, who said they were able to recognize movements in their stomachs, declared emphatically that they had repeatedly detected such movements. Often, at the outset of the cocaine effect, the subjects alleged that they experienced an intense feeling of heat in the head. I noticed this in myself as well in the course of some later experiments, but on other occasions it was absent. In only two cases did coca give rise to dizziness. On the whole the toxic effects of coca are of short duration, and much less intense than those produced by effective doses of quinine or salicylate of soda; they seem to become even weaker after repeated use of cocaine.† Cocaine was sold as over the counter drug until 1916. It was widely used in tonics, toothache cures, patent medicines, and chocolate cocaine tablets. Prospective buyers were advised (in the words of pharmaceutical firm Parke-Davis) that cocaine could make the coward brave, the silent eloquent, and render the sufferer insensitive to pain. Cocaine was a popular ingredient in wines, notably Vin Mariani. Coca wine received endorsement from prime-ministers, royalty and even the Pope. The Vatican gold medal that Angelo Mariani received for it will forever signify the popularity of cocaine through that period of time. By the late Victorian, era use of cocaine had appeared as a vice in literature, for instance, Arthur Conan Doyles fictional Sherlock Holmes. Number of admissions to drug treated programme in each year is plotted against time for both cocaine and heroin. Graph clearly displays the shift in trend from use of heroin towards cocaine. A combination gaining popularity is speedball, which is formulated by mixing heroin with cocaine. From 1980s to date, cocaine has gained popularity as drug of abuse, being used in different forms and administered via various routes, as evident by figure above which displays the escalation in crack / cocaine usage with concomitant reduction in heroin use. Prohibition: In first part of the twentieth century, with addictive properties of cocaine becoming more apparent with studies, cocaine found itself legally prohibited. Harrison Narcotics Tax Act (1914) outlawed unauthorized sales and distribution of cocaine incorrectly classifying it as a narcotic. In United Nations 1961 Single Convention on Narcotic Drugs, cocaine was listed as Schedule I drug, thereby making its manufacture, distribution, import, export, trade, use and possession illegal unless sanctioned by the state. In 1970s controlled substances act, cocaine was listed as a Schedule II drug in United States. It carries high abuse potential but also serves medicinal purpose. It is a class A drug in the United Kingdom, and a List 1 drug of Opium law in the Netherlands. Modern Usage: In late 90s and early 2000s, crack became very popular among Americans and in past few years has also taken its toll on UK. According to an estimate, U.S cocaine market exceeded $ 70 billion in year 2005, demonstrating the popularity of this menace. News reports are flooded with celebrity arrests on charge of cocaine posession or use. A section on recent facts and figures related to cocaine discusses the modern trends in greater detail later. Addiction potential: Along with amphetamine, cocaine is one of the most widely abused drugs in the world. Powerful stimulant properties of cocaine are beyond doubt. By inhibiting neuronal reuptake of excitatory neurotransmitters, dopamine, serotonin and norepinephrine, cocaine enhances synaptic concentrations of these neurotransmitters in specific brain areas; nucleus accumbens and amygdala which are referred to as the reward center of brain. During 1980s, cocaine widely replaced heroin as drug of abuse, due to its euphoric properties, wide availability and low cost. Different forms and Routes of administration of cocaine: Smoking: Crack, freebase or smokable form of cocaine, was produced and became popular drug of abuse in 1980s. Earliest reports of crack use indicate an epidemic in Bahamas from 1980. By 1985, crack gained popular ranking among drug users across America.Crack is produced by mixing 2 parts cocaine hydrochloride with one part baking soda (sodium bicarbonate). It differs from cocaine hydrochloride in being more volatile, a property that makes it better suited for inhalation administration (smoking) than cocaine hydrochloride. Smoking freebase cocaine releases methylecgonidine, an effect not achieved with insufflation or injection (described later), thereby making it a specific test marker for freebase cocaine smokers. Studies suggest that methylecgonidine is more harmful to heart, liver and lungs than other byproducts of cocaine. Inhalation leads to rapid absorption of cocaine into bloodstream via lungs, reaching brain within five seconds of ingestion. Following rush exceeds snorting in intensity but does not last long. Oral: Ancient tradition of South Americans to chew coca leaves in same manner is tobacco, is another method of cocaine consumption. Alternatively, coca leaves may be consumed like tea by mixing with liquid. Coca leaf consumers have raised a controversy over whether it should be abandoned or not. Rationale behind this controversy is that strong acid in our stomach hydrolyzes cocaine, attenuating its effects on brain; therefore, unless it is taken with an alkaline substance, such as lime, which neutralizes stomachs acid, cocaine intake should not be criminalized. Cocaine is also used as oral anesthetic, both medically and unofficially. Cocaine powder is applied to gums to numb the gingiva and teeth. Colloquial terms for this route of administration are; numbies, gummies and cocoa puffs. Another method for oral administration, commonly known as snow bomb, is to pack cocaine in rolled up paper and swallowing it. Insufflation: Colloquial terms for which are; snorting, sniffing, or blowing is believed to be most commonly employed method of cocaine ingestion in west. Cocaine is poured on a flat, hard surface and divided into fine powder before being insufflated in â€Å"bumps†, â€Å"lines†, or â€Å"rails†. Devices used as aid in insufflation are known as â€Å"tooters†. Anything small and hollow, such as straws cut short, can serve as a tooter. Injection: This achieves the greatest bioavailability, 100%, in shortest span of time, since drug is directly administered into bloodstream saving time and reduced bioavailability that occurs with drug absorption from site of drug administration into bloodstream. Resultant rush is intense and rapid. Risk of contracting blood-borne infections is greatest. â€Å"Speedball†, a mixture of cocaine with heroin used intravenously is a popular and dangerous method of cocaine ingestion. It claims credit for many deaths, including celebrities like John Belushi, Chris Farley ,Mitch Hedberg, River Phoenix and Layne Staley. ADME Pharmacokinetics: Absorption, Distribution, Metabolism and Excretion of Cocaine. Before beginning discussion about pharmacokinetics or ADME of cocaine, table below summarizes the relationship of route of administration with onset of action, time taken to achieve peak effect, duration of action and half life. (Clarke, 1986) Route of administration Onset Peak effect (min.) Duration (min.) Half-life (min.) Inhalation 7s 1-5 20 40-60 Injection 15s 3-5 20-30 40-60 Nasal 3min 15 45-90 60-90 Oral 10min 60 60 60-90 Absorption: Absorption refers to movement of drug from site of administration into bloodstream.As with any drug, absorption of cocaine depends on various factors and varies considerably with them. Factors which influence drug absorption include; drug formulation, route of administration, lipid solubility, pH of the medium, blood supply and surface area available for absorption. As evident from tabulated figures above, cocaine differs greatly in onset of action varying between 7 seconds up to 10 minutes from one route of administration to another. This is a factor of absorption of drug which depends on route of administration. Each route is separately discussed below in greater details. (Clarke, 1986). Orally administered cocaine: Cocaine induces vasoconstriction in vessels supplying oral mucosa and resultant reduction in blood supply slows down its absorption by decreasing surface area from which drug is absorbed. Therefore when orally administered, drug is slowly absorbed into bloodstream, taking roughly 30 minutes. Absorption is also incomplete; roughly one third of administered dose is absorbed. Due to slow absorption, onset of action is also delayed and peak effect is, however, not achieved until about 50-90 minutes after administration. Effect is, however, longer lasting, roughly 60 minutes after attainment of peak effect. Another factor affecting absorption of orally administered cocaine is pH of the stomach. As previously mentioned, stomach acid hydrolyzes cocaine, resulting in inadequate and incomplete absorption. To improve absorption it is common practice to take cocaine along with an alkaline liquid to neutralize acidic pH. Insufflations: Insufflations results in coating of the mucosa covering sinuses with cocaine, from where it is absorbed. Absorption is similar to that from oral cavity, cocaine induced vasoconstriction beneath mucosa results in slow and incomplete absorption (30-60%). Efficiency of absorption increases with concentration of drug. According to a study, time taken to reach peak effect via this route of administration averages 14.6 minutes. Injection: Injected cocaine is directly administered into bloodstream eliminating need for absorption. According same study, as mentioned for insufflation, time taken to reach peak effect of cocaine through injection averaged 3.1 minutes, roughly five times less than time for insufflation. Smoking: Smoking crack delivers large quantities of the drug to the lungs, resultant absorption is rapid and effects created are comparable to intravenous administration. These effects, which are felt almost immediately after smoking, are intense and last for 5-10 minutes. According to Perez-Reyes et al, 1982, volunteers who smoked 50 mg of cocaine base in a controlled study experiment achieved rapidly elevated plasma cocaine level compared to intravenous cocaine administration. Distribution: Following absorption into bloodstream, cocaine is distributed, via blood, to all body tissues including vital organs like brain, lungs, liver, heart, kidneys and adrenals. It crosses both blood-brain and placental barrier. Being lipid soluble, it easily traverses biological membranes via simple diffusion. It is believed to accumulate in brain and adipose tissue with repeated administration, owing to its lipid nature. In an experiment, distribution and kinetics of cocaine in human body were studied using Positron Emission Topography (PET) technique with radioactively labeled (carbon-11) cocaine on 14 healthy male subjects. Rate of uptake and clearance were found to vary among organs. Following results were obtained for time, in minutes, taken by radioactively labeled cocaine to reach peak value in following organs: Lungs: 45 seconds. Heart and Kidneys: 2-3 minutes. Adrenals: 7-9 minutes. Liver: 10 minutes. Liver, which is the key site for metabolism of cocaine is where distribution is most sluggish, increasing the half-life of cocaine. The Journal of Nuclear Medicine ( 1992 ) Metabolism: As already mentioned, cocaine is primarily metabolised in liver. It is estimated to get metabolized within two hours of administration. Half-life varies between 0.7 1.5 hours (Clarke, 1986), depending on route of administration among various other factors. There are three possible routes for bio-transformation of cocaine. Ester linkages in cocaine are hydrolyzed by plasma pseudocholinesterases and hepatic enzymes, human liver carboxylesterase form 1 (hCE-1)and human liver carboxylesterase form 2 (hCE-2). Benzoyl group is eliminated to produce ecgonine methyl ester. This is the major route for metabolism of cocaine. A secondary route, suggested by Fleming et al. 1990, proposes spontaneous hydrolysis, possibly non-enzymatic, followed by demethylation to produce benzoylecgonine. N-demethylation of cocaine is a minor route which leads to formation of norcocaine. Final degradation of metabolites yields ecgonine. Principal inactive metabolites are; benzoylecgonine, ecgonine methyl ester, and ecgonine itself. Norcocaine is an active metabolite and may reveal itself in acute intoxication. Metabolism of cocaine may be influenced by a number of factors: Alcohol:When cocaine is co-administered with alcohol a compound called Cocaethylene is formed. Cocaethylene is associated with an increased risk of liver damage and premature death. Pregnancy. Liver disease. Aged men. Congenital cholinesterase deficiency. In all the aforementioned conditions, except alcohol, rate of cocaine metabolism is reduced, leading to elevated levels and duration of action of cocaine, enhancing its harmful effects of on the body. Following is a schematic representation of metabolic pathways of cocaine. According to Andrew (1997) have found that the continuous use of alcohol with cocaine produce cocaethylene which is similar in the action of cocaine but it has more blood stream concentration by three to five times than cocaine as a result of its high half life. Its much attractive to be used for abuse as a result of slower removal from the body. Different types of side effects are associated with cocaethylene like liver damage, seizure and immuno compromised functioning . Cocaethylene has more possibility for sudden death by 18 25 times than using cocaine alone . Butyrylcholinesterase (BChE) has been implicated as being important in metabolism of cocaine, even though it has limited capacity to fully hydrolyze cocaine. BChE is specially essential for cocaine detoxification. A lot of research has been done to study the effect of employing this enzyme in cocaine detoxification and in anti-cocaine medications. The rate at which human BChE hydrolyzes cocaine is slow; however, scientists at Eppley Institute and Department of Biochemistry and Molecular Biology, University of Nebraska Medical Center, Omaha, Nebraska, have developed a mutant (A328Y) of human butyrylcholinesterase, which promises four fold greater efficiency in accelerating cocaine metabolism. Elimination or excretion: 1-9% of cocaine is excreted unaltered in urine along with metabolites, ecgonine methyl ester, benzoylecgonine, and ecgonine. Unchanged cocaine may also be eliminated through GI tract and/or be excreted in saliva. Most of the parent drug is eliminated from plasma within 4 hours after administration but metabolites may remain detectable for up to 144 hours after administration. Elimination of cocaine via kidneys is enhanced by acidification of urine. As already mentioned, cocaine easily traverses placental barrier, and the active metabolite, norcocaine is believed to persist in amniotic fluid for up to 5 days. In lactating mothers, cocaine and benzoylecgonine are excreted into maternal milk and can be detected up to 36 hours after administration. In smokers, cocaine is rapidly eliminated through exhalation of vapor. Ambre J et.al (1988) In an experiment, the effects of chronic oral cocaine administration in healthy volunteer subjects with a history of cocaine abuse were investigated. There were sixteen daily sessions of oral cocaine administration while subjects were kept in a controlled clinical ward. In every session subjects received five equal doses of oral cocaine at one hour interval. Throughout sessions, cocain

Pakistan China Relation Development

MARIAM ABBAS 15-10079 The Major Developments in Pakistan’s Relations with China Almost sixty years have lapsed since Pakistan and China established diplomatic relationship. The relationship between the two countries are time tested, an unbridled relationship which continues to grow and strengthen with passage of time. The area in which the two nations reside has undergone numerous Geo-strategic changes namely Sino-Indo relations, the collapse of Soviet Union, 9/11 with Pakistan becoming front line state in the war against terror and so on.In context to all these developments, China and Pakistan find themselves on the same page , each strongly supporting each other at every forum thus exhibiting exemplary and unique brotherly relationship. The intensity of the relationship can be gauged by the frequency of the visits by the two heads of the state which continue unabated. President Zardari stated on his second visit to China in February 2009, within a year of taking over the pre sidency, â€Å"Perhaps no relationship between two sovereign states is as unique and durable as that between Pakistan and China.On the Pakistan side of the Himalayas, the mighty range that separates the two countries, China is seen as a true, time tested and reliable friend that has always come through for Pakistan. That the Pakistan-China friendship is higher than the peaks of Himalayas is now a truism without exaggeration. I am certain that on the Chinese side a similar sentiment exists for Pakistan. It is a friendship rooted in the hearts and minds of the people of the two countries. 1 An insight into the significance of developments of relationships between the two nations are outlined below: â€Å"In 2005, China and Pakistan signed a land mark Treaty of Friendship and Co-operation, whereby they committed that neither party will join any alliance or bloc which infringes upon the sovereignty, security and territorial integrity of either nation, while simultaneously positing tha t both parties would not conclude Treaties of this nature with any 3rd party. †2 The above agreement is manifest of the deep rooted friendship between the two states.The security and territorial integrity of any nation is the most vital element for existence for any nation. Pakistan China relationship were based on these foundations. Having build a solid foundation of friendship, China provided physical, technical and financial support to Pakistan on a number of vital projects bringing huge economic benefit. The infrastructure projects of Karakoram highway and Gwadar Port are a few significant developments. The construction of Gwader Port will bring immense economic activity in the area.It will also afford a strategic entrance to the Arabian Sea and the Indian Ocean thus gaining a considerable influence in the region. The People's Republic of China enjoys strong defence ties with Pakistan. China fully supported Pakistan in its 1965 war against India. China's source of military equipment to Pakistan has steadily increased over the years. Ever since the dependence on American military equipment has become unreliable and prone to undeclared conditions, the induction of Chinese hardware has increased. China has helped to establish ammunition factories, provided technological assistance in modernizing existing facilities.Joint ventures such as development of JF-17 Thunder fighter air craft, AWACS system, Al-Khalid tanks, Babur cruise missiles are symbol of deep rooted military co-operation. China has also a vital strategic interest in developing relationship with Pakistan. Ever since the China – India skirmish in the sixties over border dispute which resulted in India building up its forces along the disputed border leading to Chinese military intervention, China has opted for strong partnership with Pakistan to check any hemoginistic designs of India in the region.This analogy can best be summed up by Lisa Curtis in an article titled â€Å"Extent of Pakistan China Relationship† as under: â€Å"Pakistan and China have long-standing strategic ties, dating back five decades. China maintains a robust defence relationship with Pakistan and views a strong partnership with Pakistan as a useful way to contain Indian power in the region and divert Indian military force and strategic attention away from China.The China-Pakistan partnership serves both Chinese and Pakistani interests by presenting India with a potential two-front theater in the event of war with either country. Chinese officials also view a certain degree of India-Pakistan tension as advancing their own strategic interests, as such friction bogs India down in South Asia and interferes with New Delhi’s ability to assert its global ambitions and compete with China at the international level. †3 China is fast emerging as the biggest economic super power.Economic trade between China and Pakistan is rapidly increasing at a fast pace. Chinese products have f looded the Pakistani market. â€Å" Current trade between both countries is at $ 9 billion, making China the second largest trade partner of Pakistan. † 4 China has also played a significant role in the development of nuclear power plants for peaceful purposes. The material and technical support provided by China in the completion of Chasma Nuclear Power Complex is a manifest of the deep rooted relationship.This has been despite the fact of increasingly stringent export controls in western countries and opposition by major super powers thus it is true to state that Pak-China relationship is â€Å"Time tested and All weather. † In Chinese, Pakistan found a best and most reliable friend. China always helped Pakistan economically and militarily when there was no hope for external help. On the diplomatic front, Pakistan always find China firmly standing behind its back.As a reciprocal, Pakistan was not only the first country to recognize China but it always supported China 's claim to the Chinese seat in the United Nations. Pak-China friendship is an all weather and time tested relationship based on mutual trust and respect. Both the countries enjoy convergence of views on all bilateral regional and international issues. To conclude it can be said without any doubt that Pak-China relationship is exemplary, which continues to grow and is envy for others. It is a friendship which is rooted in the hearts and mind of the peoples.

Workers without Jobs

GAP cannot reflect positive or negative externalities Involve In the consumption and production UT these externalities do affect on people's living standard. Negative externalities such as pollution brings environmental costs to society but not calculated by GAP. Positive externalities such as technological advance benefits to society but it is not count in GAP. Economic well-being would be under-value or over-value if GAP is the only single measure of economic well-being. 3. Leisure helps people enjoy a better life.In countries with lower GAP, the welfare gain from leisure can compensate the welfare loss from low GAP. Explain why frictional and structural unemployment are unavoidable in most of the economies. There are always some workers without Jobs, even when the overall economy is doing well. For example, people now prefer cell phones from Apple than from Monika. Monika decides to cut down Its employees due to the decrease of revenue. It takes time for him (the worker) to search another job that is best suited for him. In this period when matching jobs and workers, he is unemployed and it is called frictional unemployment.Another example is that now most of the textile factories decide to move to mainland China. A worker in one of these factories loses her job, however, he Is unable to learn or change new working skills or knowledge on other specialist or other field. And therefore, she cannot find a new Job In her Orlando Industry and also in other industries. This imbalance between the skills and other characteristics of some workers and the needs of workers in the labor market causes unemployment called structural unemployment.When unemployment consist only frictional and structural unemployment, unemployment is at natural rate. In most of the economies, there are always some reasons causing frictional or structural unemployment. Employment rate never fall to zero it fluctuates around the natural rate of unemployment. Therefore, frictional and structura l unemployment are unavoidable in most of the economies. What are the three major functions of money? Discuss how these functions be affected by inflation. Account and a store of value.A medium of exchange is an item that buyers give to sellers when they purchase goods and services. When you buy a shirt at a clothing store, the store gives you the shirt, and you give the store your money. This transfer of money from buyer to seller allows the transaction to take place. When you walk into a store, you are confident that the store will accept your money for the items it is selling because money is the commonly accepted medium of exchange. A unit of account is the yardstick people use to post prices and record debts.When you go shopping, you might observe that a shirt costs $30 and a hamburger costs $3. Even though it would be accurate to say that the price of a shirt is 10 hamburgers and the price of a hamburger is 1110 of a shirt, prices are never quoted in this way.

The Constitution Of The United States Essay - 1618 Words

The First Amendment is arguably one of the most important amendments ever added to the Constitution of the United States. It is designed to protect four basic freedoms: the freedom of speech, freedom of religion, the right to assembly and freedom of the press. When this amendment was drafted by the founding fathers, it was done in response to some of the events that had precipitated the American Revolution. Over time, the interpretation of these freedoms has changed as seen by various actions in government, but especially in rulings from the Supreme Court. The First Amendment has had a special importance from its beginnings to today. The First Amendment was initially created to protect freedoms that the founding fathers felt had been violated by the British or other governments at one time or another. For example, the freedom of speech and of the press was deemed important to allow citizens to speak their thoughts and opinions about the government. The founding fathers agreed with a prevailing theory at the time that governments have power mainly through the consent of the governed. Should the people become dissatisfied with the government, it is important that their opinions and thoughts be heard. Freedom of the press is closely related to freedom of speech.

As a result, you will receive a zero for the assignment. A few decades ago, scenarios like this were not prevalent. However, with the change in family structure, this situation is now very common. Over decades, television shows have reflected the social changes of the family structure. Starting with the 1960’s, a family commonly consisted of parents and their children.

Families depicted on shows such as, The Brady Brunch and The Jeffersons, showed conflict relationships and blended families. During this decade, the family lifestyle became more diverse. The burden of social critics focused on the rising black middle-class and women working outside the house. During this decade, people started to second guess family life, as seen on The Brady Brunch and The Jeffersons (Television and Family 1). The Brady Bunch started to show families with rebellious childr en. The show attempted to steer clear of the political and social issues at the time. Non-white characters were not introduced and gender equality was exhibited. The show tried to represent the countercultural aspect of the late 1960’s into the 1970’s. Boys and girls that played together started to date. These children kissed behind their parents back and this was foreshadowing the dysfunctional family structure. Parents were not given as much importance and the American public was feeding off this negative energy from the show. The show aired during the times the production knew they would grab attention from a young audience. Some children watching this show were home-alone while both parents were at work, or the children came from divorced families.

Implementation Critical Success Factors

Question: Discuss about the Implementation Critical Success Factors. Answer: Introduction Enterprise systems are regarded as large scale, cross-functional as well as data centric software, which can provide services for all the subunits of organisation. Enterprise systems are comprised of different categories like Enterprise Resource Planning, Supply Chain Management, Knowledge Management System, Customer Relationship Management and Document Management System. The firms had started invested in a huge amount for enterprise system since 1990. The amount invested behind Enterprise system has summed up to 230 billion dollars in 2008. The failure of the firm after implementing these technologies are also too high, therefore the system has to be implemented successfully in order to gain competitive advantages. Enterprise system softwares are too expensive. The average cost of installation sums up to 15 million dollars. These characteristics of Enterprise system suggested that it requires assessment in a systematic way (Pollock and Hyysalo 2014). Therefore, the long term assessm ents of post implementation of Enterprise systems are very much significant. It takes long time to be implemented within the organizational system. However, the success or failure gained at the first time does not determine the future outcome after the installation of system. On the premise of the current literature, we recognize two classes of big business frameworks. These classes contrast by the degree of the association that is (in a general sense) influenced by establishment of the framework. Usage of some venture frameworks requires an extensive variety of hierarchical units to be included, for these frameworks to give full usefulness as indicated by their plan particular. ERP frameworks, for example, can't successfully work unless the data, exchanges, and elements of various areas of the association, for example, acquisition, creation, showcasing and deals, circulation, fund, and human asset administration are incorporated through a mutual information store. Correspondingly, SCM applications can best satisfy their useful guarantees by planning and streamlining the exercises identified with development as well as capacity for crude materials, advance work stock, and finished products all through the entire inventory network of the organization. KMS programming is additionally gainful when the data and information resources of company are altogether gathered, composed, consolidated, prepared, and shared (Bear et al. 2016). We sort these venture frameworks whose execution includes and influences a wide range of hierarchical substances as association wide frameworks. Alternate class of big business frameworks is more restricted to a predetermined number of hierarchical units. These frameworks are normally more straightforward and less demanding to-utilize and are not really executed all through the entire association. For instance, CRM frameworks are utilized to assemble, track, and dissect an organization's contacts and associations with its present or imminent clients. The Marketing branch of the organization is typically the authoritative unit that is specifically required in and influenced by a CRM establishment. Actually, for a useful CRM framework, all the different firm divisions are not really incorporated. DMS applicatio ns can be introduced for particular offices and needn't bother with full hierarchical incorporation also. A DMS is an automated framework to cooperatively make, alter, chronicle, and distribute electronic reports of solitary or different spaces of an association with comparable documentation procedures and prerequisites. We order these undertaking frameworks whose execution river to a restricted cluster of authoritative substances as space particular frameworks. Cost and Benefit of Enterprise System Affecting Organisational Performance Several numbers of benefits as well as costs has contributed for enterprise system. The benefits could be discussed in four stages: Richness and Reach of Information: Enterprise system helps in making innovative, enhanced, more precise, and generally out of reach data accessible for various units of company; this yields in excellent management and organizational control, enhancing policy as well as coordinating exercises, selection of education, and quick reaction times (Ram, Corkindale and Wu 2013). Automation and Integration of process: Firms business processes are altered and assist streamlined by implicit prescribed procedures of the venture programming; this yields in authoritative reserve funds through manual, redundant methodology as well as operational investing funds through proficient and adjusted forms of business (Shukla et al. 2016). Maintenance of Information system and modifying it: Enterprise software acts like a focal as well as coordinated framework of IT rather than few inexactly coupled subsystems and isolated applications of business brings about lessening of costs of data frameworks through scale of economies and extension (Nwankpa 2015). Competitiveness of Organisation: Through various components, enterprise system selection helps in authoritative learning, strengthening the workers, business deftness, quality benefit, and loyalty of consumer that can be additionally help in development as well as upper hand of firm (Ha and Ahn 2014). The immediate impacts enterprise systems on performance of organisation are recognizable when they encourage or bolster current procedures, schedules, work arrangements and item/benefit offerings of organisation for making them proficient, without advancing drastically better approaches for doing or organizing things or presenting in a general sense new items or administrations. For instance, an ERP framework brings about regulatory and operational sparing by dispensing with manual, dreary errands of information passage and announcing (Soto-Acosta, Popa and Palacios-Marques 2016). This can be meant bring down factor expenses of creation and from that point to lower costs and thus higher deals if request is value flexible. Correspondingly, a SCM application prompts bring down stock levels and request handling times which can again show as lower creation costs and higher incomes. KMS and DMS programming result in inside efficiencies through encouraging information sharing furthermore, archive looking and therefore advance profitability and development. Principle Drivers behind Business for Adopting SCM Production: It is the capability which measures supply chain in making or supplying products. Factories as well as warehouses are the facilities to production. The crucial choice that directors confront when making creation selection is the manner by that determine the exchange off responsiveness as well as effectiveness. The chance that plants as well as distribution centres are working with a considerable measure of overabundance limit, they can be highly adaptable and react swiftly to wide swings for request of products (Lin 2014). Offices where all limits are being utilized are unequipped for reacting effortlessly to changes sought after. Then again, limiting costs and overabundance limitation is fixed without moving limit being unused as well as not creating income. So more overabundance limit that exists, the less effective the operation moves toward becoming. Inventory: Stock has been spread all through the network of production as well as incorporates everything regarding crude material for work which are on process to completed merchandise that the makers held, merchants, as well as retailers in a store network. Chiefs must choose where they required themselves to position for the exchange off responsiveness and proficiency. Holding numerous stocks permits the organization and whole network production to be exceptionally receptive to changes on the request of clients (Vijayan and Kamarulzaman 2016). Notwithstanding, the creation as well as capacity of stock is a cost and for accomplishing large amounts of effectiveness, the cost of stock should be kept as low as expected under the circumstances. Location: Location alludes to geological reference of network production offices. It includes the choices that are been identified with exercises should be performed in every office. The responsiveness against exchange off proficiency here is the preference whether to include exercises in fewer areas to pick up scale of economies as well as productivity, or for decentralizing exercises in numerous areas close to clients and providers with the end goal for operations to be more responsive. When selecting on location preferences, administrators requires in considering variables scope which identify with a given area incorporating the cost of offices, labour cost, abilities accessed to the workforce, foundation conditions, duties and levies, and nearness to providers and clients. Choices of location have a tendency to be extremely significant choices since they invest a huge amount of cash to long haul policies. Location choices affect the cost and execution attributes of an inventory network (Christopher 2016). Once the number and offices areas are been resolved, that likewise characterizes the conceivable ways quantity by which products can stream while in transit till to the last customer. Area choices reflect an organization's significant technique to build and convey its products to showcase. Transportation: This alludes for development from crude material to completed merchandise between various offices in store network. In transportation the exchange off responsiveness as well as proficiency is exhibited on the decision of mode of transport. Quick methods for transport, for instance, planes are responsive additionally exorbitant. Slower modes, for instance, ships as well as rail are exceptionally taken a toll productive however not as responsive (Pinto and Allui 2016). As expenses of transportation may be as much as 33% of the expense of working for a network of, selection made here are vital. When to Implement Enterprise System in Business Enterprise system could be implemented by the company when there are presences of various softwares for various processes. When many of the software are running on the system it can cause the system to become typically slow. It can lead to inappropriate data receiving from sales that can in turn affect the inventory management. Enterprise system helps in integrating these systems therefore, the business can run on one unit database. When the access for information gets difficult Enterprise system could be use. It helps the executive in getting the better view of the real time operation of business (Bragilia and Frosolini 2014). When accounting consumes more time this software should be implemented. The entire financial database comes to a single database. ERP lies within the middle of framework as well as clients and not considering the pipeline position. Every one of the errands ought to be finished in successive way. ERP has diverse information accumulation focuses and it should interface with every single diverse organization of specific information. The information gathering part helps in dealing with the assignments course of action that should have been performed. These elements ought to be mulled over to be given significance as under. Every one of the occupations that must be overseen as per ERP courses the request at proper time to the coveted office (Galliers and Leinder 2014). The improvement is finished by keeping the procedure thought. The booking of the employment time ERP decreases number of times client needs to enter the information to drastically decrease blunders. These sorts of occupation are computerized so that the mistakes coming about because of the manual work can be diminished. Furthermore, the blunders comin g about because of the manual work (Sykes 2015) Likewise the human mistakes like wooziness are totally diminished. To play out every division its required capacity ERP takes all information and configurations. Every one of the occupations that are to be performed in the well configuration ought to be kept up as far as it. It additionally worried to make the customers and the end clients fulfilled. It is especially useful for the execution of authoritative process (Chang 2016). The arrangement of ERP is a noteworthy undertaking for any association however the ERP have great advantages. The associations who truly actualize the ERP procedures are really profit by the procedures. The advantages that are yielded by executing the ERP are long term. There are some main problems that happen amid ERP arrangement are identified with employment work keeping aside the surface level thinking of better request following and administration. The arrangement of the ERP application in the association is an issue since every one of the frameworks mu st be perfect to acknowledge its design. The idea of the request following administration emerge in order to check if the requests are is change the business procedure it is basic to change the mindset of the association's workers. It is likewise imperative to keep the straightforwardness between the business and representative relationship. It likewise helps in seeing how and why the specific representative carries on especially (Lohe and Legner 2014). The support to corporate objectives socialization and correspondence must be finished. The mingled business helps expanding the contacts and the systems administration of the association. It additionally helps in expanding the cooperative attitude of the organization. The great correspondence and the mingling process helps in expanding the social contact with the clients and it likewise help to make the association mainstream.
