Economics The Russian Experience Essay Example for Free

Economics The Russian Experience Essay The economy of the Soviet Union was based on a system of state ownership and administrative planning which meant that the state was the single decision organ in economic matters. The economic growth was guided by what was then called Five Year Plans crafted by the national decision makers appointed by the state. This approach made it easy for the resources to be harnessed to achieve set objectives. The economic set up concentrated more in building capital goods, machine manufacture and the chemical industry. The economic setup was top down model that offered little option for feedback to move to the decision makers. This made it hard for the decision makers to assess the effects of their decisions with a view to eliminate destructive ones. It therefore made it hard for the decision makers to abandon earlier decisions that failed to work or that produced negative results. (http://www. answers. com/toic/history-d-the-soviet-union-1985-1991). The economic setup, otherwise called communism, often resulted into the problem of over or under production of goods. The system paid little attention to the production of consumer goods and this led to black markets thriving. This black market had a counter effect on the economic agenda of the planners. The system was also very bureaucratic delaying issues that required urgent decisions. This scenario led to a back logging of decisions, which overwhelmed the decision makers with time. Middle level managers began to agitate for freedom to deal with customers and suppliers directly for them to more effectively respond to the economic laws of demand and supply. This agitation built up to eventually break the Soviet Union because the decision makers and the political leaders of the time failed to respond to these demands responsibly. (http://www. answers. com/toic/history-d-the-soviet-union-1985-1991). The economic setup of the Soviet Union had made some big gains, which enabled them to become industrialized faster than other economic fronts. Failure to respond to arising issues was what contributed to its downfall. Strong institutions had already been setup such as the agricultural sector, foreign trade as well as the financial sector. All capital goods were collectively owned with little exceptions. Individual property ownership was minimal. The ownership controversy also contributed to the Soviet Union breakup. Since then Russia has had to undergo intensive reform program to enable them to respond to the largely capitalistic world economy (Moszczynska, undated) A key sector that is the focus of the reform process is the financial sector. The Russian economy is reliant on oil and the fluctuations of prices affect the economy adversely. To alleviate such adverse effects, the financial sector needs reforms because it offers smoother transition into the envisioned economic setup. A challenge facing Russia and other countries as they transit from command economy to the free market economy is imbalance created by foreign trade. These countries have begun to import goods that were in short supply but on the other hand exports have began to decline. This slows down the recovery process since exports spurred growth previously. When the exports are more than the imports, a country is performing well economically and this is reverse for these former Soviets. Consumption growth had for a time led to an increment is real wages but productivity growth has stagnated those gains. This again is due to the heavy reliance on the oil industry for economic growth (Barnard, 2000). In addition, there is little investment outside the oil and metal industries. This means that as much as the motive is to create wealth for the citizenly, there cannot be much success if no considerable investment is made. In fact investments in other areas has been declining over time. The investment climate in Russia is still hostile which slows down the ability of the reform process to spur growth. The economic system only favor large business establishments leaving small and medium sized enterprises struggling. The government’s authorization requirements are stringent while corruption has been rife. This has led to more resources being allocated to large firms. With the medium sized enterprises grounded, no much growth can be achieved. The banking system is also inefficient since it only lends to the large establishments. The reform of the banking sector has largely depended upon political climate but a legal framework is needed to effectively reform this sector. A better framework to regulate the banking industry has to be put in place (Kahan, 2001). The reform process of the Russian and other former Soviet countries are on the right track. There are enough challenges in the implementation process of the proposals but they are gaining ground. Under performing areas have shown indications of growth. The recovery process, though, calls for political will among the leaders to drive the process. No much progress would be realized if political will is lacking. The effects of the Cold War need to be eliminated from the fore. The Russian economy has great potential and if the strategies respond appropriately to upcoming issues, the Russian economy would perform better. The Russian economy performance had put Russia ahead of other countries. It was not entity based on wrong principles. The major problem was the bureaucratic system that had been set that made it difficult to respond to rising issues. If the economy is to acquire the envisioned status it once had, it has to respond to arising issues.

Effects of Type 1 Diabetes on Pregnancy

Effects of Type 1 Diabetes on Pregnancy Introduction Diabetes mellitus is a serious endocrine disorder caused by a deficiency or diminished effectiveness of the hormone insulin and is categorized into two sub-categories, type 1 and type 2, together with the lesser known variant gestational diabetes (Burden, 2003, pp30-32). Type 1 diabetes is thought to be a genetically controlled autoimmune disorder that presents in childhood and is also know as juvenile onset diabetes or insulin dependent diabetes. Type 2 diabetes usually occurs in older, obese individuals; however, this type of diabetes is becoming increasingly more common among children and adolescents. Debatably, this is because of the increase in childhood obesity because of the sedentary lifestyle some children are adopting in today’s society. There is also an hereditary predisposition to type 2 diabetes. If one or both parents have type 2 diabetes the offspring is at an increased risk of getting the condition (Rosenbloom et al, 1999, pp345). It is important to note that g estational diabetes that is a complication of pregnancy is different from the pre-existing diabetes in pregnancy that will be discussed in this essay. It is thought that approximately three to five percent of pregnancies are complicated by type 1 diabetes. During pregnancy diabetes mellitus can have a damaging detrimental affect on both maternal and foetal health. Conversely, diabetes is affected by the physiological changes that take place during pregnancy (Bewley, 2002, pp47-48). This essay will examine the effects of type 1 diabetes on a seventeen year old (Carol) that is six weeks pregnant. The essay will start by investigating the prevalence of diabetes mellitus in order to acquire a global picture of the disease. The aetiology and physiology of type 1 diabetes will then be discussed. This essay will then go on to consider the signs and symptoms of the condition and its effects on Carol now and in the future. Next the complications of diabetes in general and during pregnancy will be discussed, considering the effects on Carol and her unborn child. The effects of type 1 diabetes on the developing embryo, foetus and mother will be addressed. Finally, the hereditary link for type 1 diabetes will be considered and the essay will then be concluded. Epidemiology Diabetes mellitus is a growing global and public health problem. The World Health Organisation (2006, p1) estimates that the problem could escalate to an estimated three hundred million people by 2025. It is thought that approximately one and a half million people in the United Kingdom have diabetes mellitus. Type 1 accounts for approximately twenty percent of cases of diabetes mellitus. Type 2 diabetes accounts for more than eighty percent of cases with more than one million people diagnosed in the United Kingdom (Burden, 2003, pp30-32). The aetiology and physiology of type 1 diabetes mellitus This section focuses on the causes of disease and the biological aspects of diabetes mellitus. As mentioned type 1 diabetes results from the complete absence of the hormone insulin that is involved in glucose metabolism. It is thought that it is an autoimmune disease in which the bodys immune system attacks and destroys the beta cells in the islets of Langerhans that are embedded in the tissues of the pancreas (See diagram 1). Diagram 1, this shows the islets of Langerhans that are deeply embedded with the tissues of the exocrine pancreas (http://cal.man.ac.uk/student_projects/2000/mnby7lc2/pancreas.htm). Diagram 1 The pancreas has two functions the exocrine cells produce digestive fluids and the endocrine cells produce hormones. It is the endocrine insulin producing beta cells that are important in the role of diabetes mellitus. The beta cells (see diagram 2) make insulin and when the body’s immune system attacks it results in the destruction of these cells. As the cells die insulin production stops and the consequences of this are impairment in function of, and damage to many of the organs in the body. Diagram 2 shows the insulin producing beta cells that are found in the islets of Langerhans (http://cal.man.ac.uk/student_projects/2000/mnby7lc2/pancreas.htm). Diagram 2 It is not known exactly what triggers this immune attack, but susceptibility to the disease might be inherited. The autoimmune attack may be triggered by reaction to a virus infection. The attack is thought to be carried out by the T cells of the immune system (Waugh and Grant, 2001, p234). In Diabetes mellitus there is too much glucose in the blood. When carbohydrates are eaten they are broken down into glucose. This process is known as gluconeogenesis and occurs in the liver and kidneys. The level of glucose in the blood is regulated by the naturally occurring hormone insulin. Insulin promotes transport and entry of glucose into the body’s cell and tissues. Glucose is essential to the production of energy within the cells and without it cellular death will occur (Tortora and Grabowski, 2003, p627). Signs and symptoms of type 1 diabetes mellitus This section will examine the signs and symptoms that Carol would have exhibited before diagnosis and during the course of the condition. The initial clinical indication of untreated diabetes relates to elevated blood sugar levels, and loss of glucose in the urine. When there are excessive amounts of glucose in the urine, water is taken out of the body in large amounts by the process of osmosis (Waugh and Grant, 2001, p235). This results in polyuria (increased urine output) and that leads to dehydration. Dehydration causes polydipsia (increased thirst) leading to increased fluid consumption. The inability to utilise glucose energy eventually leads to weight loss despite excessive hunger (polyphagia). Dramatic weight loss would have been a clinical sign exhibited by Carol. Some patients also complain of fatigue, nausea and vomiting. Patients with diabetes are prone to developing infections of the bladder, skin, and vaginal areas; this is because hyperglycaemia can disrupt the action o f phagocytes that are help to fight infection. The immune system in diabetes sufferers is suppressed and this limits the body’s ability to resist invasion by bacteria or viruses. Fluctuations in blood glucose levels can lead to blurred vision and extremely elevated glucose levels can lead to lethargy. Diabetic ketoacidosis is a serious medical condition resulting from uncontrolled diabetes. Ketoacidosis is caused by lack of insulin and occurs when the body uses fat as an energy source and ketones build up in the blood. Ketoacidosis starts slowly and builds up to a life-threatening condition that can result in coma and possible death (Burden, 2003, pp30-32). Carol may have exhibited all or some of these symptoms when first diagnosed and she is exhibiting symptoms of weight loss, tiredness and mood changes at present. Debatably, this is because here blood glucose levels are uncontrolled due to her pregnancy. Having said this however, research has found that adolescents (in particularly girls) are not vigilant in all aspects of managing their condition. Having a certain level of hyperglycaemia will enable a person to eat, yet remain thin. In today’s society that is obsessed with thinness teenage girls might undertake such an action (Carson, 2000, pp36-37). Complications of diabetes mellitus in general and during pregnancy There are many long-term clinical complications of diabetes that affect various systems and organs of the body. Having diabetes mellitus increases the risk of developing irreversible microvascular or macrovascular disease. Microvascular diseases include retinopathy, nephropathy and neuropathy and macrovascular diseases include ischemic heart disease, stroke and peripheral vascular disease. These disease are all a result of poor glycaemic control (Donnelly et al., 2000, pp1062-1066). Diabetic retinal and renal disease will be discussed in more detail as pregnancy can result in further complications and poor pregnancy outcome. Diabetic retinopathy is an eye disease that can lead to blindness. The longer a person is diabetic, the higher the chances are of developing the condition. It is thought that prolonged periods of hyperglycaemia cause damage to the blood vessels in the retina at the back of the eye. Diabetic retinal disease can deteriorate during pregnancy and poor glycaemic control in the first trimester is associated with the progression of retinopathy (Hill, 2004, p40-44, Donnelly et al, 2000, pp1062-1066). Carol should have her retinas examined at the start of her pregnancy to establish if she has pre-existing retinopathy. If retinopathy is diagnosed than Carol will need to have regular eye tests to monitor the condition. Continuous good glycaemic control will stop the condition from progressing. Diabetic renal disease or nephropathy is again caused by hyperglycaemia resulting in damage to the capillaries in the kidneys. The kidneys are then unable to undertake filtration of amino acids and this leads to hypertensive disease. Women who have pre-existing nephropathy are at an increased risk of poorer pregnancy outcomes. This is because high blood pressure as a direct result of nephropathy can cause pre-eclampsia. This in turn can cause premature delivery and maternal death (Donnelly et al, 2000, pp1062-1066, Hill, 2004, pp40-44). It is important therefore, that Carol’s blood pressure is monitored throughout her pregnancy as hypertension is a sign of pre-eclampsia (Bewley, 2002, p50). Effects of type 1 diabetes on the developing embryo, foetus and mother It is suggested that type 1 diabetes mellitus in pregnancy puts the foetus and the developing baby at far greater risk than is imposed on the mother. Various, potentially damaging problems can arise from foetal reactions to maternal glucose levels. Therefore, if a mothers glucose levels are high, the foetus will have correspondingly high levels (Bewley, 2002, p51). If a mothers blood glucose levels are continuously high (hyperglycaemia) during the first-trimester there is an increased risk of congenital anomalies such as neural tube defects that include spina bifida, abnormalities of the heart and anatomical abnormalities of the bones (Confidential Enquiry into Maternal and Child Health, CEMACH, 2005, p37). Neural tube defects are major birth defects of a baby’s brain or spine. They happen when the neural tube (that later turns into the brain and spine) does not develop in a correct anatomical manner resulting in damage to the brain or spine (Tortora and Grabowski, 2003, p1073). This happens within the first few weeks that a woman is pregnant, often before a woman knows that she is pregnant. Another condition that is attributed to maternal diabetes is that of Polyhydramnios. This is the medical condition of too much amniotic fluid in the amniotic sac. Polyhydramnios is generally due to maternal diabetes and is thought to be caused by increased foetal urination. This is caused by the elevated amount of glucose in the mothers blood that cross the placenta and makes the blood of the foetus hyperglycaemic. This results in increased urine output from the foetus. In pregnancies affected by Polyhydramnios, approximately twenty percent of the neonates are born with a congenital anomaly of some type. There are a number of risks that are increased in polyhydramnios including cord prolapse, placental abruption and perinatal death (Pilu Nicolaides, 2006) Other adverse neonatal conditions that are attributed to maternal diabetes are neonatal mortality, premature birth, hypoglycaemia and an increased risk of respiratory distress syndrome (Bewley, 2002, p51). There is also an increased risk of macrosomia that can lead to an augmented possibility of shoulder dystocia and an assisted delivery. Macrosomia is related to maternal hyperglycaemia and is characterised by larger-than-normal birth weight in a newborn at over 4500 grams (10 pounds). High levels of glucose in the mothers blood readily pass through the placenta to the developing baby stimulating insulin production in the baby. Insulin is a potent growth hormone and so fat is deposited which can result in a large baby. This can cause shoulder dystocia and birth trauma because the baby will not easily fit through the birth canal. Postpartum, the newborn continues to produce excessive quantities of insulin that can result in the infant being hypoglycaemic.The mother has an increased pr evalence of pre-eclampsia, postpartum infection, postpartum bleeding, and caesarean section (Reece et al, 2004, p169) . It appears from the research indicated that Carol needs to have optimum glucose control for her own health and for that of her baby. Women with type 1 diabetes should have a pre-conception glucose level within normal limits that is an HbA1c of below 7 percent. The management of pregnancies complicated by pre-existing diabetes mellitus should begin prior to conception (Reece et al, 2004, pp481). However, at seventeen it is quite possible that Carol’s pregnancy was unplanned. Is type 1 diabetes mellitus hereditary? It is thought that there may be a genetic or inherited susceptibility to diabetes. If a parent has type 1 diabetes, the chance that their children will be affected is about twenty-five to forty percent. In the instance of type 1 diabetes various genes have been indentifyed that might predispose an individual to the disease. Therefore, it is suggested that this genetic mutation might incline an individual to diabetes. It is debated that a genetic element is not, in itself enough to cause autoimmunity. It is suggested that external influences such as a viral infection are thought to trigger the disorder. It can be said that type 1 diabetes is an immunological disease that has a genetic background cause (Littorin, 2001, pp1033-37). It is possible therefore, that Carol has inherited a genetic susceptibility to type 1 diabetes from her mother, but environmental factors might activate the actual disease. Conclusion Diabetes is an increasingly common disease that if not controlled can cause a number of disabling lasting complications that can have a destructive influence on both quality and quantity of life. Type 1 diabetes is thought to be an autoimmune disease that leads to the complete destruction of the insulin producing beta cells in the pancreas. Insulin is needed to help glucose enter the cells of the body. Glucose is required in the cells to produce energy for normal cell function. It is possible that there is an hereditary link that predisposes an individual to the condition. As Carol was diagnosed with type 1 diabetes mellitus at the age of seven and she has had difficulty in controlling her blood glucose levels, she is at an increased risk of developing diabetic complications. It appears that her pregnancy will also intensify the effects of some of the complications affecting both her own health and that of her baby. It is suggested that Carol needs to attain good glycaemic control for her own health and for the health of her baby. Bibliography Bewley C (2002) Diabetes in pregnancy.

The System Hacking Cycle

The System Hacking Cycle System hacking means to hack system password within the operating system. Many hacking attempts start with attempting to crack passwords. However, passwords are the key piece of information needed to access a system. Users, while creating a password, often select password that are prone to being cracked. Passwords may be cracked manually or with automated tools such as dictionary or brute-force method, each of which are discussed in this paper. Scanning and enumeration is the first part of ethical hacking and contains the hacker target systems . Enumeration is the follow-on step once scanning is complete and is used to identify computer names, usernames, and shares. Scanning and enumeration are discussed together because many hacking tools perform both. The system hacking cycle consists of six steps:- a. Enumeration b. Cracking Passwords c. Escalating Privileges d. Executing Applications e. Hiding files f. Covering tracks Enumeration occurs after making the IPv4 protocol independent of the physical network, the designers decided to make the maximum length of the IPv4 datagram equal to 65,535 bytes. This makes transmission more efficient if we use a protocol with an MTU of this size. HowÂÂ ­ ever, for other physical networks, we must divide the datagram to make it possible to pass through these networks. This is called fragmentation. The source usually does not fragment the IPv4 packet. The transport layer will instead segment the data into a size that can be accommodated by IPv4 and the data link layer in use. When a datagram is fragmented, each fragment has its own header with most of the fields repeated, but with some changed. A fragmented datagram may itself be fragmented if it encounters a network with an even smaller MTU. In other words, a dataÂÂ ­gram can be fragmented several times before it reaches the final destination. In IPv4, a datagram can be fragmented by the source host or any router in the path although there is a tendency to limit fragmentation only at the source. The reassembly of the datagram, however, is done only by the destination host because each fragment becomes an independent datagram. Whereas the fragmented datagram can travel through different routes, and we can never control or guarantee which route a fragmented dataÂÂ ­ gram may take, all the information is provided by other means such as the hop-by-hop options or other protocols. In its simplest form, a flow label can be used to speed up the processing of a packet by a router. When a router receives a packet, instead of consulting the routing table and going through a routing algorithm to define the address of the next hop, it can easily look in a flow label table for the next hop. In its more sophisticated form, a flow lab Many hacking attempts can initialize with to attempt crack passwords. Passwords are the important information which is required to login a system. Users, when creating passwords, often select passwords that are difficult to guess. Passwords are stored in the Security Accounts Manager (SAM) file on a Windows system and in a password shadow file on a Linux system. Manual Password cracking involves attempting to log on with different passwords. The hacker follows these steps: 1. Find a valid user account for password test. 2. You can create list of possible passwords. 3. Arrange the passwords according to possibility 4. Try each password. 5. Try and try for correct password. In its simplest form, a flow label can be used to speed up the processing of a packet by a router. When a router receives a packet, instead of consulting the routing table and going through a routing algorithm to define the address of the next hop, it can easily look in a flow label table for the next hop. In its more sophisticated form, a flow label can be used to support the transmission of real-time audio and video. Real-time audio or video, particularly in digital form, requires resources such as high bandwidth, large buffers, long processing time, and so on. A process can make a reservation for these resources beforehand to guarantee that real-time data will not be delayed due to a lack of resources. The use of real-time data and the reservation of these resources require other protocols such as Real-Time Protocol (RTP) and Resource Reservation Protocol (RSVP) in addition to IPv6. To allow the effective use of flow labels, three rules have been defined: 1. The flow label is assigned to a packet by the source host. The label is a random number between 1 and 224. A source must not reuse a flow label for a new flow while the existing flow is still active. 2. If a host does not support the flow label, it sets this field to zero. If a router does not support the flow label, it simply ignores it. 3. All packets belonging to the same flow have the same source, same destination, same priority, and same option. 2. ACCOUNTING MANAGEMENT The Internet is a wonderful thing. It allows knowledge to be shared with the world. But what if you want to use the Internet to share knowledge with just one person? When web pages, e-mail, and even passwords are transferred across the Internet, they are free to be seen by anyone who cares to look. You may ask, Who is going to be looking, anyway? The answer, in most cases, is nobody. Anonymity can be your security. This is especially true of your Internet presence from home. However, the situation changes when you use your credit card over the Internet, or when you are a business on the receiving end of a credit card transaction. In such cases, anonymity clearly doesnt provide enough security. Furthermore, what if you receive a sensitive document, but you are unsure if the person who sent it really is who they claim to be? How do you know that this same document wasnt tampered with between the time it was sent and the time you received it? And what if you need to protect sensitive data on your web site, or perhaps you want to protect the data in transit to the user, or authenticate the user with a stronger authentication method? It prevents users from monopolizing limited network resources. It prevents users from using the system inefficiently. Network managers can do short- and long-term planning based on the demand for network use. Integrated Windows authentication is the most secure method of authentication, but it is available only with Internet Explorer. This authentication type had been known previously as NTLM authentication and Windows NT Challenge/Response authentication. In Integrated Windows authentication, the users browser proves itself to the server using a cryptographic exchange during the authentication process. Integrated Windows authentication supports both the Kerberos v5 and the NTLM (NT LAN Manager) protocols for authentication through the Negotiate package. If you are using Active Directory, and the browser supports it (IE 5 or above with Windows 2000), Kerberos is used; otherwise, NTLM is used. Both Kerberos and NTLM have limitations on their use. Interestingly enough, each ones strength is the others weakness. Kerberos generally works with proxy servers, but it tends to have a hard time with firewalls. NTLM generally works through firewalls, but it tends to have a hard time with proxy servers. 1. A manager checks an agent by requesting information that reflects the behavior of the agent. 2. A manager forces an agent to perform a task by resetting values in the agent database. 3. An agent contributes to the management process by warning the manager of an unusual situation. 3. PASSWORD INTEGRITY Authentication is an important feature of any secure web site. Every time a client browses to a web site, it needs to be authenticated before it can access the resources it is requesting. By default, that authentication all takes place on the server, and the client isnt even involved. Some authentication settings can make for easy access to a web site, but sometimes you want to limit who sees what information on your site. This is where more restrictive types of authentication come in. If your computer is renamed, the Internet Guest Account does not change and continues to use the old machine name. Because user accounts use security identifiers (SIDs) to identify themselves, changing the computer name doesnt affect the account name. When IIS receives a request, it automatically attempts anonymous authentication first. If anonymous authentication fails, it attempts to log on the user using another logon method. If no other authentication methods are enabled, IIS sends a 403 Access Denied HTTP error message to the client. You can use any user account that you wish for anonymous access, including the Administrator account. You can change access settings in the items Properties windows Directory Security tab, accessible by right-clicking the item in the IIS Microsoft Management Console (MMC) snap-in and choosing Properties. (By the way, even though you can do it, dont use the Administrator account for anonymous access.) Basic authentication is a widely accepted means of authentication. Because all the information is presented and transmitted in clear text, its easy to use and makes for easy program interoperability, but the passwords can be found out faster than you can say security risk. Both the web server and FTP server components in IIS support Basic authentication. 4. CONCLUSION The simplest and the oldest method of entity authentication is the password, something that the claimant possesses. A password is used when a user needs to access a system to use the systems resources (log-in). Each user has a user identification that is public and a password that is private. We can divide this authentication scheme into two separate groups: the fixed password and the one-time password. In this group, the password is fixed; the same password is used over and over for every access. This approach is subject to several attacks. 4.

Essay About Family: The Wives Tales :: Personal Narrative essay about my family

I am convinced that my mother and my father found solace in each other because they could no longer bear the madness of their brothers and sisters. Most of my aunts and uncles have second names to mark their exceptionality. My father’s eldest brother is called â€Å"Urgent† because he only calls when he needs money and always tells the kids to leave the message: â€Å"Urgent. Urgent, tell your dad to call me back urgent!† My father’s youngest brother calls himself â€Å"Castro† because his first name is Fidel. This brother shaves his head and wears a goatee to look more like the real Castro. My mother’s brothers and sisters are no better. One of Mom’s brothers married a woman named â€Å"Daughter,† which is just beyond me. Really, her parents must have been at their wits’ end; I wonder whether they had so many daughters that they surrendered to making all the children’s names alike. Mom’s sister, Rajo, â€Å"Auntie Money,† is the most fun, especially during tax season when she tries to convince her accountant to get her a deduction for all the gifts, trips, and baubles she buys her nieces and nephews. Chandra is the most laughable of Mom’s seven sisters. Aunt Chandra is always trying to pass her â€Å"pearls of wisdom† down to everybody, making herself look foolish to great public audiences. In Guyana, she held an elite position at the national post-secondary school, teaching who knows what. I often wonder at the ignorance and superstition behind the things she says. At one of our frequent dinner parties, the ladies in the kitchen were having a conversation about motherhood and how hard it is to choose between staying home with their kids and going back to work. While everyone else settled down to eat, Chandra, Mom and I busied ourselves making pepper sauce, cleaning the clutter off of countertops and refilling bowls of food. Conversation halted as the clacking of spoons, smacking of tongues, and the machinations of eating and drinking supplanted the lively chattering. Chandra took the opportunity to offer up a piece of her mind: â€Å"You know, guys, I have always noticed that I had my kids when there’s a full moon. Babies can only be conceived under a full moon. I am telling you, those scientists don’t know it yet. But I know.† I could not keep myself from laughing. Amazingly, Fidel’s wife, Nadira, reproached me, â€Å"No, it’s true.

The Northern Lights Essay -- essays research papers fc

The Northern lights are poetry, they are nature's light show, and they are quantum leaps in the oxygen atom. They are elementary particle physics, superstition, mythology and fairy tales. The northern lights have filled people with wonder and inspired artists; they have frightened people to think that the end is at hand. More exact explanations of the phenomenon could not be given until modern particle physics were developed, and knowledge about details in the earth’s magneto sphere has been based on measurements from satellites. When the northern lights are seen over Tromsà ¸, it happens in a set pattern, although this pattern varies considerably. The outburst starts with a phosphorocent glow over the horizon in northwest. The glow dies out and comes back, and then an arch is lit. It drifts up over in the sky. And new arches are lit and follow the first one. Small waves and curls move along the arches. Then within a few minutes a dramatic change is seen in the sky. A hailstorm of particles hit the upper atmosphere in what is called an aurora sub-storm. Rays of light shoot down from space, forming draperies, which spread, all over the sky. And they really remind us of draperies or curtains, which are flickering in the wind. And you can see a violet and a red trimming at the lower and upper ends. Or the colors are mixed all together, woven into each other. The curtains are disappearing and forming all over again by new rays of light shooting down from space. Above our head we cans see rays going out in all directions forming what is called an aurora corona. After 10 to 20 minutes the storm is over and the activity decreases. The bands are spread out, disintegrating in a diffuse light all over the sky. We can not see individual pockets of light, but the total effect is bright enough to enable us to make out details of the countryside around us. If we look very carefully, we can see the remains of the northern lights display as faint, pulsating flames. Clouds of light which is turned on and off regularly every 5 - 10 seconds as though by an electric light-switch. The natures own gigantic light show is over. What causes the northern lights? To answer this, we start with the sun whose energy production is far from even and fluctuates on an 11-year cycle. Maximum production coincides with high sunspot activity when processes on the sun's surface throw particles ... ...ll over the sky. 7) Bands of northern lights one above the other, raising towards the zenith indicates that the sub storm is starting. 8) Rays of light shoot down from space tells about higher activity. 9) Draperies are formed with waves at the lower end. 10) Curls and waves wave along the draperies. 11) The draperies look as if they are flickering in the wind. Maximum activities close. 12) The interaction between the moving charged particles and the earth’s magnetic field creates a charging magnetic field. The particles stream down along the magnetic field lines. 13) Rays and draperies can die out in one place of the sky, and form at another. 14) During the maximum of a sub storm, the whole sky can be full of light. 15) An all-sky (fish eye) picture showing that the draperies are stretched from east to west, through zenith. 16) When the activity reaches Zenith, by an optical illusion, it seems like the rays stretch out in all directions above our heads. This form of the northern lights is called aurora corona.

Was Ho Chi Minh More of a Nationalist Than a Communist?

Was Ho Chi Minh more of a nationalist than a communist? Most people in America firmly believe that Ho Chi Minh was a communist first and foremost. The public was inundated with stories of his visits to Russia and China. We heard repeatedly how his support from communist countries was being used to take over and create a communist stronghold in South East Asia. What we didn’t hear was the rest of the story. The Vietminh under Minh’s leadership had an alliance of sorts with the U. S. during WWII. The common enemy, the Japanese provided a sort of strange bedfellows situation where the communists supported the ouster of another foreign invader. After the war, the Vietminh set up governmental structures in the country assuming Vietnam would return to a sovereign state. Minh himself made repeated overtures to the U. S. and other countries for support in his quest of independence (Young, 1991. p 14). Even the Vietnam declaration of independence signaled Minh’s nationalistic view (Gettleman, et al, p 26). As a pragmatist, Minh realized that the U. S. as not going to support his independence so he turned towards Russia and China for support. Minh walked a fine line with these countries to keep his supply line open without losing his independence. Some say that ability showed his true skills as a diplomat (Obituary, 1969). On the flip side of the equation, Minh was a true and through communist. He lived and breathed the communist ideals and was ruthless in achieving them. It h as been said that he was a great contradiction. Ho Chi Minh was known as the great communist leader while at the same time ultimate nationalist (Ho Chi Minh, 2006).

Education in Private and Public Schools Essay

Over the past years, there has been lots of interest among the policy makers to compare private and public elementary and secondary schools in the United States. In a sense, both private and public schools follow the same general goals set out in 1979. These goals as Sizer pointed out are expected to serve equally well both the American’s public and private elementary and high school (p. 349). These goals according to Sizer aimed to develop the students’ fundamental scholastic capacity and to make them competitive and responsible individual. Both the private and public are expected to come up with this end, and to touch most aspects of an adolescent’s existence, mind, body, values and career. Generally, as reported by Teresa Mendez in her article said that private schools had performed very satisfactory during the latest Standardized Test for scoring higher than public school. This report summarized the concept that private schools are getting more professional in performing their jobs. This report is very significant since America has set educational policies that are common for both public and private schools. Sizer had stated in his book â€Å"What High School Is† that despite America’s multi-diverse culture and decentralized school government, most schools across America are common in terms of vision or goals related to academic achievements of students. However, as one will look into Sizer’s discussion of similar circumstances and scenario inside a high school in California, he or she can notice some problems regarding students’ attitude and behavior inside and outside the classroom. In particular Sizer portrayed this concept through Mark who is a student who is bored and uninterested with school requirements. On the other hand, there are teachers and staffs who are busy with work and mindful of responsibility at home. These two parties are both elements that comprise education and yet, it seems that the academic goals or vision are not emphasized. This is because; Mark being a recipient of the knowledge appeared to be passive and stubborn since knowledge is somehow undesirable on his view, while teachers and staff are not good mover or instruments of those knowledge. This concept presented by Sizer is common in America, and he seems trying to reconcile the educational goals with proper implementation by adapting some changes in terms of school policy. To better understand this, it is important to analyze the school system in America and how it tries to meet the present needs of the educational system of America, as well as its impact to the existing scenario in most schools. Given the same objective, we can expect less difference although we may expect much similarity between public and private high school education. But studies conducted by the National Center for Education Statistic showed that there are many differences in the public and private education. They explained that although the central goal of education is the same with public and private but both can freely choose objectives and goals related to what has been set up by the government (p. 7). This means that, each school has freedom to set objectives and goal, yet, all of them should match the overall goals of the central government. These goals are directed towards the fundamental academic achievements, career and economic competence, citizenship and civil responsibility, aesthetic awareness and cultural diversity of the students (Sizer, p. 349 – 350). In general, education in America as they view it should cater to the growth and development of individual for the country’s fundamental advancement whether in public or in private schools. It is evident in most schools in America that even though, private and public schools follow through same principles in terms of educational system, and yet, they are differ in many ways from curriculum to policies. The findings of the study done by the National Center for Education Statistic reveals that majority of the public school have curriculum with emphasis on basic literacy and reading skills as their most important goal, while private schools chose to put priority on religious development of their students (p. 8). However, other results of analysis and studies of NCES showed that faculties in public schools are more professional than those in the private school as public school uses a full range of professional living requirements. The article published by the NCES entitled â€Å"Teacher Professionalization and Teacher Commitment: A Multilevel Analysis† noted that teachers in public school are required to have a substantive training in areas of specialization, complete accredited training program, and passage of examination (p. 25). Whereas teachers in private schools, the report appears to be less professional on many ways (p. 25). The report also cited that there is more turnover of teachers in private schools than in public schools. This indicates that public school have more stable teaching force than the private school as public school teachers are receiving much higher salaries which is one of the important factor for teacher to stay in their work. Aside from that, the article noted that private school teachers receive inferior salaries that cause high turn over on the part of private schools. Thus, the report shows that despite the privileges and benefits received by teachers in public school, these teachers have shown lesser commitment as compared to teachers in private schools. In comparison, neophyte teachers from private and public school have greater commitment than those in senior level or those teachers receiving higher salary (p. 26-27). Other factors associated with increase in commitment in teachers according to study are: high-end-of career salary and individual autonomy for teachers. The professionalization and commitment of teachers affect so much the credibility of education imparted to students. Policies implemented in the school system certainly affect the general performance of the school. The goal which the school is heading have influenced not only on the teachers but among the student as well. Roelande Hofman said that studies have shown that private schools have a positive effect on academic achievement (p. 119). Hofman pointed out that private school have the freedom to the kind of students they want to enroll and kick out students who display behavior that violates their own set of rules. Because of this autonomy, it gives the private school authority to reject or to accept students which the public school had only limited autonomy (p. 19). On students and parents preference, private school seemed to attract more because of selection policy. Hofman noted that in public school, the diversity of students’ background as the individual characteristic of students home environment affect with the school. It means that the behavior and conduct of students in school affects the general performance of the school in the areas of character and conduct as Sizer has portrayed in his book, many of the students seemed to have lost appetite to seriously search and acquire knowledge through schooling. In fact, students’ activities inside the campus appeared to be unmonitored by the school authorities as students can transact illegal drugs inside the school premises. Whereas in private school, students activities are daily monitored and any unacceptable manner or any violation of the given rules would easily be met with either warning or punishment. The issue is that the student feels more responsible to study well as they carry in themselves the pride that they there among other students like them who are truly sincere in their study. In general, it appears that though the teachers in the public school have a much better salaries and benefit systems and are more stable in their position compared to their peers in the private schools, yet private school teachers are more committed in their work than teachers in the public school. Second, the policy and goals and vision seem to work well in the private school despite of the fact that teachers in the public school are more professional and more trained and more fitted to work because of the specialization in the field they are handling. Third, that despite of the fact that teachers in private school are less qualified in the position given the requirements required for a public school teacher, yet private school appeared to be preferential choice of parents and students for one more reason disciplined. The similarities between public and private have been quite obvious in the levels of commitment of female teachers than their male counterpart. Both the public and private teachers reflect that female teachers are slightly committed than their male counter part. The article cited that those who are more experienced teachers have less commitment than those new ones which is the same with the private schools. Aside from this, there was not much given similarities between the public and private school. In fact, some authors were even exaggerated to express that what is between public and private are distinct difference in all aspect. Thus, the similarities given were limited only in comparison of male and female teacher in the public as well as in the private school.
