The rate of reaction Essay Example for Free

The rate of reaction Essay The experiment will end when I take the third reading of 30cmisodium thiosulphate solution, 20cmi water. The safety goggles are the most important aspect of the experiment, as it is crucial to maintain a high standard of safety when working with corrosive chemicals. Diagram: Graph to show predicted appearance of results Method and Results I carried the experimental investigation as stated in the Plan section, under Experimental Procedure. Having gained satisfactory results, I have arranged them in a table. Table of Results cmi of Na2S3O2 Time taken (seconds) Mean results solution 1 2 3 (average). To draw my graph, I used the reciprocal function on my calculator on each of the averages, to gain a number that can be used to draw up a graph to show direct proportionality between 1/Average Time taken and concentration of sodium thiosulphate. Conclusion In terms of drawing a conclusion from my results, I can say that they compliment my prediction, as shown by the similarity in my prediction graph (a straight declining line), and also generally in the description of inverse proportionality. As anticipated, inverse proportionality is shown between the concentration of sodium thiosulphate and the time taken for the solution to turn opaque. Na2S2O3 + 2HCl 2NaCl + S + H20 + S02 Scientific Explanation As the hydrochloric acid particles and the sodium thiosulphate particles collide into each other solid sulphur is given off and gives the solution a yellowish tinge. After a while this sulphur builds up and clouds the solution to the point when the cross beneath becomes cloaked. The particle collision theory states that the more of a particular chemical there is present in a solution (in my case sodium thiosulphate) then the more it will collide with the other particles (the particles that concern my experiment are the hydrochloric acids). Therefore, if a 100% concentrated solution of sodium thiosulphate is added to a solution of hydrochloric acid, all the particles will collide more often, and the reaction will occur quicker than a 60% sodium thiosulphate 40% water solution, because the 40% water has replaced what used to be sodium thiosulphate, thus reducing the speed of the reaction. Another point to make is the time of the reaction increased rapidly towards the end of my results. Evaluation The results I have obtained were of quite a high general standard, however there were a few minor anomalies. One anomaly was the second result for 30cmi of sodium thiosulphate solution. Here is the extract from my table of results, with the anomaly shown in italics. 30 472 506 493 490 It stood out as being an abnormally long time taken, in comparison with the other two results, and also seen in the effect on the graph of results it has. This could be for a number of reasons. Firstly, going back to the planning section, there is the issue of temperature control, which was left aside despite being recognised as an influencing variable. If left uncontrolled then chances are that anomalies like the above will occur. I have decided not to ignore this result because the unconformity is only slight Also, the slight inconsistencies between each group of three results are also down to the fluctuating room temperature. These errors however, are only slight and therefore are not to be worried about in terms of being insufficient for drawing solid conclusions. I still believe my results to be reliable, as they average out quite impressively. There are minor differences in each of the sets of three readings that were bound to occur due to uncontrolled temperature. The differences are merely fractional, and the averages worked out give a very clear picture of ideal results. There were bound to be the odd fluctuation in the length of time for the solution to turn opaque because of human error. Every time it is myself that judges when the solution has turned sufficiently opaque and I stop the watch systematically. Because my reflexes are not perfect it may seem like one measurement was longer than another, when it was only my slow reactions that distorted the result slightly. The particle collisions theory may also be to blame because if the region of the solution directly above the cross X had a larger amount of collisions, just by chance, then the reaction time would be quicker than average. I would suggest that in further experiments, the variable of heat be included, and the pair who carries out the investigation work as a team and play different roles in the experiment. One of them should time the reaction as I did, and the other should keep the temperature as constant as possible. That way anomalous results will be almost entirely eradicated. The other two issues of human reflexes and of chance of areas of collision are unfortunately uncontrollable. Some kind of computer will surely be able to judge when a solution has turned opaque better than a human being. To test my conclusion, I would suggest doing a similar investigation, but with magnesium strips instead of sodium thiosulphate. It will be easier to judge reaction time because one would only have to stop the watch upon seeing the magnesium completely dissolve. Also using magnesium in an experiment is a lot simpler and cheaper than using sodium thiosulphate.

Examining Islam In Malaysia Religion Essay

Examining Islam In Malaysia Religion Essay Malaysia is modern Muslim country where more than half of its 26 million people have embrace Islam as their religion. Halal is an Islamic religious guide to how Muslims should live their lives from the way their food is prepared to how their personal and social relationships are conducted. In Malaysia Halal is a concept accepted by all, by both Muslims and non- Muslims. The majority of businesses in Malaysia sells products or offer services that are Halal endorsed. The Malaysia Halal Certification is globally respected. In our ever progressive world, it has become increasingly challenging for Muslims to determine whether the food or drinks they consume are religiously acceptable or Halal. This Halal and non-Halal problem is not only limited to food and beverage but also to other products and services. For Muslims living in a totally Islamic country like Saudi Arabia, the Halal question is not an issue at all. For those living in a multiracial Muslim country like Malaysia, although Halal food or services are readily available and easy to obtain, there is a need for the authority to monitor and enforce standards to ensure Halalness particularly when the products or services are made, sold, prepared or provided by non-Muslims. However, the real challenge is for Muslims living in a country whose population is predominantly non-Muslims. Extra diligence is needed for these Muslims to enjoy everything Halal. Most striking is that there are approximately 1.9 billion Muslims in the world who are consumers of Halal foods. As such the Halal food market is the largest food market in the world. Among the Halal importing countries are those which have one of the highest per capita incomes in the world, have the fastest growing middle classes in the world, import a significant proportion of their food needs and have the highest rates of population growth in the world. Malaysia will be developed International Halal Food Hub for monitoring and standardization the Halal food product. The Halal certification will be gives if the food ingredients are Halal. This certification of Malaysia Halal standard are also will be strengthened and aggressively promoted internationally. HALAL BEEF PRODUCT Halal products are fast gaining worldwide recognition as a new benchmark for safety and quality assurance. Products that are produced with Halal certification are readily acceptable by Muslim consumers as well as consumers from other religions. This acceptance is due to the wholesomeness concept of Halal, which covers not only the Shariah requirement, but also the hygiene, sanitation and safety aspects. Halal certification is a powerful marketing tool for both the Muslim and non-Muslim producers, as there are an increasing awareness on the part of Muslim consumers all over the world on their obligation to consume Halal food. The Arabic word(Halal) means lawful or permitted. In the Holy Quran, Allah commands Muslims and all of mankind to eat of the Halal things. Basically, Allah Al Mighty knows what is best for us to eat. And normally all the Halal food are very clean and safe from any disease. But for non-Halal food, you always can find some interesting facts relating to sickness. This following products are definitely Halal such as milk (from cows, sheep, camels, and goats), honey, fish, plants which are not intoxicant, fresh or dried fruits, legumes nuts like peanut, cashew nuts, hazel nuts, walnut, grain such as wheat, rice, rye, barley, and oat. Basically, all food is Halal except meat from swine such as pork, ham, pork-based products and by-products such as sausages and gelatin. Animals improperly slaughtered or already dead before slaughtering is due to take place. Animals killed in the name of anyone other than Allah (for example, by anyone other than a Jew, Christian or Muslim, or as part of a pagan sacrifice), intoxicants, blood and blood by-products, foods contaminated with any of the above products. Most of the desserts use non-Halal Gelatin that comes from pigs. Focus about the beef, they are only Halal if they are slaughtered according to Islamic Law. The procedures that we must do at the beef are the animal must be slaughtered by a Muslim. The animal also should be put down on the ground or held it if it is small. The throat of the animal must be sliced with a very sharp knife to make sure that the 3 main blood vessels are cut. While cutting the throat of the animal (without severing it), the person must pronounce the name of Allah or recite a blessing which contains the name of Allah, such as Bismillahirahmannirrahim, Allah-u-Akbar. Islam prohibits the meat of animals that are slaughtered without reciting the name of Allah and those that are slaughtered whilst pronouncing a name other than Allah. Mentioning the name of Allah during slaughter is actually a way of seeking permission from God for taking the life of the animal for the sole purpose of sustenance. The prohibition to recite a name other than Allah during slaughter acts as a safe guard to a Muslims faith. Islam is a religion which promotes monotheism and rejects any form of polytheism. Mentioning a name other than Allah is regarded as a polytheistic act, thus such act is not permissible during slaughter. For more information, they lead the cow into an area, line its head up with where the piston comes out, and BAM! The cow is unconscious, hung by its ankles, and sent to where the slaughter takes place. Regarding poultry, a common practice is to render them unconscious by electrocuting them before slaughter. Slaughtering is to be done from the front of the neck, between the throat and the head of the breast bone (Libba). The throat/oesophagus (Mirree), windpipe/trachea (Halkoom) and the two jugular veins (Wadijan) are cut in the neck without severing the spinal cord. This cut severed the arteries to the brain of the animal, thus depriving the brain of blood supply. As a result, the brain loses consciousness due to insufficient oxygen. This renders the animal unconscious, causing the animal the least amount of pain.   By contrast, the Islamic method of slaughtering does not allow for animals to be killed in front of other animals. It requires an extremely sharp blade and the swift incision of the major veins in the neck to facilitate in a painless, quick blood loss and death. Before the slaughter takes place, the animal is examined for overall health. If the animal is deemed unhealthy, it cannot be slaughtered for food. The animal is slaughtered in such a way that most of the blood exits the body. The goal is to slaughter the animal, limiting the amount of pain the animal will endure. DEPARTMENT OF ISLAMIC DEVELOPMENT MALAYSIA (JAKIM) HISTORY In 1968, the Conference of Rulers Pakistan has decided that the need for a body to mobilize efforts for development and advancement of the Muslims in Malaysia, in line with Malaysias status as an Islamic country that has strong international and world attention. Recognizing this, a secretariat to the National Council of Religious Affairs was established, to maintain the purity of faith and the teachings of Islam. Secretariat was subsequently developed as the Religious Department of the Prime Minister who was later promoted again to the Islamic Affairs Department (BAHEIS). On January 1, 1997, in line with the development and progress of Islam in the country has stabilized, the Department of Islamic Development Malaysia (JAKIM) is established by the Malaysian government took power and the role (BAHEIS). FUNCTION OF JAKIM Formulation and standardization of Islamic law Formulate, review and amend laws for the standardization of Islamic states. Streamline and standardize the Islamic law throughout Pakistan. Act enacts Islamic law and the federal territories.

WHY ISLAM FORBIDS PORK Pork is the most commonly eaten forms of meat around the world, there are over 100 million metric tons of pork is consumed throughout the world. And pork can be served in different forms such as cooked or form of sausages. However, we know that Islam not eating pork but what is the reason they forbids pork. So now, we go to discuss about it. We know that food and drink have a direct effect on our health. That is why Islam prevents to unhealthy food. Because they believe both physical and moral health are equally important for a healthy society. Therefore, the abstention from eating pork is one of the steps taken by Islam to practice hygiene and to attain purity of soul. To cultivate our inner faculties, Islam insists upon the cleanliness of body and the purification of soul through Salaat (prayers), Zikr (remembrance of Allah) and other devotional duties. Islam teaches us how to attain the virtues and how to give up bad habits because both good and bad grow in the man according to his upbringing, education and environment. A human being has natural desires: food, sleep and sex being the three primary ones. He has also natural emotions: sorrow, happiness, love, fear, disgust and avarice etc. Islam doesnt recommend the complete abrogation of these impulses but offers a method of controlling them through religious education and discipline. The prohibition of eating pork in Islam is relevant in this context. There is a saying in English that a man becomes what he eats. According to physicians and medical experts, pork is a harmful diet. Consumption of swine-flesh creates lowliness in character and destroys moral and spiritual faculties in a man. Despite Islam allows Muslims to eat clean thing. However, in the consumption of meat, Muslims are required to be selective and distinguish the Halal foods. Dr. E. Kazim. M.D, in his article Medical aspects of forbidden foods in Islam (July 1981 issue of Muslim Journal) has described diseases carried or caused by the flesh of swine. He writes: The pig is a scavenger. It is an omnivorous animal. It eats everything. There are many diseases carried from swine to man, particularly parasite infestations. Lately extensive research has been focused on senility-old age is characterized by hardening of inner lining of the blood vessels of the heart, brain etc. a process called atherosclerosis. When a clot forms, it results in coronary thrombosis or a heart attack, cerebral thrombosis or stroke. Dr. Glen Shepherd wrote the following on the dangers of eating pork in Washington Post (31 May 1952): One in six people in USA and Canada have germs in their muscles trichinosis 8 from eating pork infected with trichina worms. Many people who are infected show no symptoms. Most of those, who do have, recover slowly. Some die; some are reduced to permanent invalids. All were careless pork caters. He continued: No one is immune from the disease and there is no cure. Neither antibiotics nor drugs or vaccines affect these tiny deadly worms. Preventing infection is the real answer. After reading the statement of Dr. Shepherd, one can realize that there is no real guarantee of safety when eating pork that one would not be affected by trichina worm. That is why modern doctors advise three prohibitions during illness: no liquor, no pork and no smoking. At the end we know that Muslim forbids pork because they respect their religion. They believe their GOD will care for them. But if they are under famine, they still can eat pork to survive, its no sin. CONCLUSION At the end, we found that Halal food have many benefits and thats why many people either Muslim or non Muslims, would like to choose Halal food. Halal meat is beneficial for nutrition and health. Only healthy animals can be slaughtered. It is done by Muslims who are trusted and experienced. The meat itself will have no blood clots within the veins-giving it a longer shelf life. Animals will be treated with mercy and respect and will be blessed with the name of God (Allah) prior to slaughter. Ethnic and religious considerations are not the only reasons why consumers are choosing kosher- and Halal-certified foods. Many perceive the extra supervision implicit in the certified foods assures higher quality and safer food products. According to Packaged Facts report, Market Trend: Kosher- and Halal-Certified Foods in the US, resonates with a similar report from Mintel released earlier this year, which concluded that the majority of US consumers who buy kosher foods do so for perceived quality and safety reasons, rather than for religious ones, and there is no reason to assume things are any different in Australia and New Zealand. They study found that three in five people who buy kosher food do so because they perceive it to be better quality, Halal food also have a lot of nutrition and they feel safe to eat it, and it free from any disease other that, availability to get Halal food is easier. The two most popular markets for Halal food are South-East Asia and the Middle East. By going through the Halal certification process, food processors will open up the possibility of additional clientele and often they will not even have to make changes to their product to get such certification. There are four steps in processing of Halal food that is: application, submission, processing certification and post certification. And whats the important in the steps of processing is certification attests that a product/service is suitable for Muslims and finished products which adhere to Halal manufacturing procedures carry a Halal symbol on the label. We know that all equipment used in the production of Halal foods must be free from contamination with non-Halal items and comply with the necessary hygiene and sanitation requirements. All ingredients must all be Halal as well. Favorable perceptions Many consumers believe that Halal and kosher food is produced under stricter supervision than is provided by government inspection and for many consumers the Halal and kosher symbols guarantee that the food is free of contaminants or disease and no preservatives added. The research indicated that more than half of consumers who purchased kosher products did so because they considered them to be safer than products not certified as kosher. Mintels research has shown that kosher was the most frequently used claim on food and drink products launched in the US in 2008 which, as the Jewish population is not increasing, suggests that the growing interest may be more to do with food safety than religion. Aside from religious requirements, kosher and Halal supervision adds another level of quality control in responding to the needs of the discerning consumer. Simply by adhering to the kosher and Halal requirements and having foods certified, processors will broaden their market.

Example Physics Essay

Example Physics Essay The Motion of a Mass Spring System The example of a mass attached to the end of a spring is a powerful tool in physics due to the fact that it is analogous to many physical phenomena. To be able to use this example to elegantly describe other more complex systems it is crucial to first fully understand how this simple system works itself. The force acting on a mass attached to a spring at a given position is given by (Serway, 2003: 437). F= -kx (Eqn 1) This equation may be derived from Newton’s Second Law of motion, which states that the force on a mass is proportional to the rate of change in momentum. A mass and spring system can be described as a Simple Harmonic Oscillator and there are some fundamental equations that govern the motion of such a system (Serway, 2003: 436). ω= √(k/m) (Eqn 2) Equation two shows how the angular frequency (ω=2Ï€*frequency) of an object oscillating due to it being fixed to a spring that is inversely proportional to the mass of the object. k is a constant, known as the spring constant that is defined by the properties of the spring. k can be easily determined experimentally for a given spring by changing the mass attached to the spring and measuring the frequency. Due to the periodic nature of such a system as that which can be described using equations one and two, they are known to be in simple harmonic motion. The motion of a particle over time is described effectively by a cosine wave (Serway, 2003: 436; Hayek , 2003; 562). x(t)=Acos(ωt+à Ã¢â‚¬ ¢) (Eqn 3) Equation three shows how this motion can be mapped over time where A is the amplitude of the oscillation, and à Ã¢â‚¬ ¢ is a term to correct the phase. This can be plotted to show how the mass and spring system will move over time. The figure above shows how a mass on a spring will behave in a frictionless universe while obeying Newton’s First Law of motion. A useful trait of the Simple Harmonic Oscillator is that the equations for the velocity and the acceleration are easily derived from that of the position equation (Serway, 2003: 436). V(t)=-Aω.sinà ¢Ã‚ Ã‚ ¡(ωt) (Eqn 4) a(t)= -Aω ² cosà ¢Ã‚ Ã‚ ¡(ωt) (Eqn 5) For brevity the phase term (à Ã¢â‚¬ ¢) has been omitted from these two equations as it can be assumed that phase is the same. These two equations give valuable insight into the nature of as mass on a spring and how its velocity and acceleration is linked. The interesting thing to note is that velocity is governed by a sine waveform, yet acceleration is dependent on the cosine waveform. What this means is that when the particle on the spring has minimum velocity it will have maximum acceleration, it also means that when the mass is travelling at its maximum velocity it has minimum (possibly zero) acceleration. Realistically however, most situations where a simple harmonic oscillator may be applied will involve a resistive force of some description, such as friction in the case of a mass on a spring. The effect this has on the motion of the mass and the spring system can be seen in the figure below. It is clear to see on the above figure that the presence of friction causes the amplitude of the oscillation to decay over time. This effect is known as damping. In a damped system that has no external force driving the oscillation itself, the rate at which the oscillation decreases is directly proportional to the resistive force being applied to it. The damping force is at its greatest when the particle is moving at its fastest velocity and at a minimum when the acceleration is at a maximum. There are three types of damping in an oscillatory system, underdamping, over-damping and critically damped. Underdamped is where the amplitude of the decay envelope does not decay rapidly. Critically damped systems are the fastest to return to equilibrium and will have a decay envelope that allows one oscillation over the entire damping period and will decay towards zero rapidly during this period. Over-damping occurs when there are no oscillations (as seen in critical damping) however there is an infinite time to return to equilibrium (Hayek , 2003; 567). The equation which describes this damped oscillation is given by: F= -kx-l dx/dt (Eqn 6) Here the original equation for the force is extended by a first order differential term relating to the change in the velocity due to the damping constant l. Equation six is able to be expanded into a more useful form by applying Newton’s Second Law, which gives: (d ² x)/(dt ² )+2Dω_0 dx/dt+ω_0 ² x=0 (Eqn 7) This equation now contains a first and second order differential equation relating to the velocity and acceleration respectively of the particle. Equation seven looks to be much more complex than that of equation six, however it is now in a considerably more useful form as it allows to see equation six in terms of the angular frequency of the system. D is the damping ratio and is given by D= l/(2√mk) , taking into account the damping coefficient, the spring constant and the mass of the particle. To fully understand the motion of the mass and spring system there must be consideration of the energy within the system. This may be done with the help of some simple drawings. The blue lines indicate the spring and the solid red block with a blue border indicates the mass. From the figures it is possible to imagine stretching the spring, this means that there is a force acting on the mass and if it is held at this stretched point (x) the mass will have a potential energy U. should the mass be released from this point it will have a maximum velocity Vmax and a maximum Kinetic energy KEmax. The total energy in the system at any one point in time is the sum of the potential and kinetic energies. E(t)=KE+U (Eqn 8) E(t)=1/2 mà £Ã¢â€š ¬Ã¢â‚¬â€œv(t)à £Ã¢â€š ¬Ã¢â‚¬â€Ã‚ ²+1/2 kà £Ã¢â€š ¬Ã¢â‚¬â€œx(t)à £Ã¢â€š ¬Ã¢â‚¬â€Ã‚ ² (Eqn 9) By substituting the formulae for velocity and position (equations three and four) into the energy equation it is possible to simplify this further. E(t)= 1/2 kA ² [à £Ã¢â€š ¬Ã¢â‚¬â€œsinà ¢Ã‚ Ã‚ ¡(ωt)à £Ã¢â€š ¬Ã¢â‚¬â€Ã‚ ²+à £Ã¢â€š ¬Ã¢â‚¬â€œcosà ¢Ã‚ Ã‚ ¡(ωt)à £Ã¢â€š ¬Ã¢â‚¬â€Ã‚ ² ] (Eqn 10) E(t)=1/2 kA ² (Eqn 11) The elegance of this simple algebra is that for an oscillating mass on a spring the energy in the system at any given point in time is completely independent of time. If there are dissipative or driving affects occurring during the oscillations then the amount of energy in the system will change, however for a closed system this fact holds true. This equation occurs in many areas of physics, for much more complex systems than a single mass on a spring. These equations can be applied to pendulums, resonant electrical circuits (RLC circuits) (Mispelter, 2006: 35) such as those used to detect Radio and TV signals, or even in quantum mechanics and the time independent Schrodinger equation, where it is found that a quantum harmonic oscillator, such as a particle in a potential well (Schrà ¶dinger, 1926: 1054), is one of the few quantum mechanical problems that it is possible to find analytical answers for. If the Hamiltonian for such a system is examined it is shown that its structure is very similar to that of equation nine (Schrà ¶dinger, 1926: 1057; Levitt, 2012: 144). H ÃÅ'‚= p ÃÅ'‚/2m+1/2 mω ² x ÃÅ'‚ ² (Eqn 12) p ÃÅ'‚ is the momentum operator that forms the kinetic half of the Hamiltonian and x ÃÅ'‚ is the position operator which calculates the potential part of the Hamiltonian (Schrà ¶dinger, 1926: 1052). It is obvious that the simple classical physics still applies to this quantum system. These are some of the situations where this type of motion is observed and the table shows how the equations are manipulated to fit the system under examination ( Hayek , 2003; 562; Mispelter, 2006: 38; Dirac, 1958: 108; Boylsestad, 2010: 871). In conclusion the mass and spring system’s motion is elegantly described by some simple mathematics that can be manipulated to suit systems that have external forces acting on the motion of the system. The beauty of this is that the mathematics can then be applied to much more complex systems. References: Boylestad, Robert. (2010) Intrductory Circuit Analysis, 12th edition. Pearson. Dirac, P. A. M.

Real Boys Essay -- English Literature Essays

Real Boys While Reading the book Real Boys by Dr. William Pollack, I realized that our society is holding boys to contradictory standards aiding the problems that many of them face while in adolescence. This book introduces the reader to numerous boys who share their feelings of shame and despair in trying to live up to the "Boy Code". Pollack feels the pain that comes from boys prematurely separating from their mothers puts them on the cycle to hardening themselves emotionally. The one acceptable emotion becomes anger. Throughout the book Pollack encourages parents to take time with their sons in helping them express their feelings while showing them empathy and love. Pollack discusses the ways parents can help their boys escape from the gender straightjacket that is imposed upon them. Pollack exposes myths that negatively portray boys as macho creatures shaped by testosterone with no social skills. He instead presents examples of boys who are emphatic as a result of nurturing parents and educates the reader to be aware that boys express their love through action and work. Pollack includes chapters regarding the different but equally important role of mothers and fathers in bringing up their sons. He also writes about the effect of healthy relationships with peers and the devastation that some boys feel when they discover they are homosexual. Pollack takes on the schools in failing boys in a number of ways but specifically for failing to understand the Boy Code. Boys continue to lose self-esteem as the mask of masculinity tightens and they conform to what society expects from them, interfering with their ability to learn effectively. Dr. Pollack not only gives us the problems that face the adolescent boy he also gives us suggestions to remedy and rectify the situation. This is nice instead of simply offering negative statements he actually offers the reader a solution. Another beneficial aspect of Dr. Pollack’s writing is the fact that he uses so many references to his research and the research of other notable psychologists instead of over emphasizing the personal instances in his own life. When he wants to emphasize a point with a real life person, he uses a third party. When speaking of these contradictory codes that a young boys is taught to live by, Dr. Pollack says: "Boys have had to learn to walk a fine line. Have intimacy without sentimen... ...ollack talks on breaking down gender stereotypes; he seems to perpetuate them by seeming to insist that the mom be the central part of upbringing. Extensive sections on single moms but the only discussion of single dad households is two sentences which state that research showing relatively positive outcomes (i.e. relative to mom getting sole custody, not relative to intact families) is controversial. Pollack notes that Dads are more likely to suffer from depression after a divorce but does not draw the logical reason. Dads lose far more than moms in a divorce. Yes moms economic status goes down more, but she tends to keep what is really important... the kids. Even today the courts are horribly biased against men in divorce cases. A mom must be totally unfit to not get at least joint custody, dad has to fight for minimal visitation rights. These are however minor quibbles with the book, the central principle of the book: Today’s boys are in big trouble, and much of that tr ouble stems from never being allowed to show any negative emotion other than anger, is a very important one. Boys are not toxic they need our love and support, even if they put on a tough self-sufficient disguise.

Aspects of Marriage Present in Pride and Prejudice by Jane Austen :: Jane Austen Pride and Prejudice Marriage Essays

Aspects of Marriage Present in Pride and Prejudice by Jane Austen There are lots of aspects of marriages in Jane Austen’s novel Pride and Prejudice. There are marriages of love, convenience, physical attraction and mercenary. The marriage between Mr. Wickham and Lydia is partly due to physical attraction and mercenary. The marriage between Elizabeth ad Mr. Darcy and Jane and Mr. Bingley are due to love. The marriage between Mr. Collins and Charlotte Lucas is base on convenience. The Marriage between Mr and Mrs Bennet is also due to physical attraction. The novel was set in 1796 and was published in 1813. The England during this period of time was far more class conscious. The main characters in this novel come from a class called gentry; this is the class above the emerging professional class and below aristocracy. Class was more to do with breeding than with wealth. Rules were set for everything, rules for dressing, rules for travelling, rules or introducing yourself to others and rules for behaving. In this period of time women were not allowed to work. However they could become governesses. They could not inherit wealth from their father, and the Bennet sisters were no exception therefore Mr. Collins was their heir to Mr. Bennet’s property. The marriage between Mr. and Mrs. Bennet was based on physical attraction. You can see that they do not understand each other. There is a contrast between both of their character. Mr.Bennet is intellectual and likes to spend time reading in the library while Mrs. Bennet is loud, hasty and likes to spend her time gossiping and trying to finding husbands for her daughters. Mr. Bennet enjoys mocking his wife â€Å"†¦ I have respect for your nerves they are my old friends†¦Ã¢â‚¬ . Mr. and Mrs Bennet also have different opinions and ideas of their daughter’s future â€Å"†¦ Your mother will never see your face if you do not marry Mr. Collins, and I will never see you again if you do†¦Ã¢â‚¬ . You can tell that this is a marriage based on physical attraction because Mr. Bennet advises his daughter not to make the same mistake that he did my marring Mrs. Bennet â€Å"†¦I know that you could be neither happy nor respectable to your husband, unless you truly esteemed your husband†¦. My child, let me not have the grief of seeing you unable to respect you partner in life†¦Ã¢â‚¬  he is in a way hinting that he cannot respect his wife. Mrs. Bennet is unaware of this as she dose not know her husband very well. Mrs. Bennet’s character is very similar to the character of Lydia. Both like officers and both act loud and hastily.

Mass Communication Essay

According to historical evidence, oral exchange of news was the common method of communication in ancient India, whereas the modern medium of communication system was originated since the end of the eighteenth century. The present inquiry deals with variety of sub topics when analyzing Indian mass media. The coverage, popularity, diversification, westernization, commercialization, technology, entertainment, education, politics, sex, violence, women and children, are some of such topics which are deeply and sociologically analyzed in the study. The print media, Radio, TV, and Films are taken into account as comprised of Indian mass media throughout the study. Having understood that the nature of mass media is determined by social conditions, a Herculean attempt is made to understand Indian mass media as a manifestation of social implications in association with the society of India. According to study, Indian mass media is a symbol as well as a reflection of India society, which is extremely heterogeneous, diverse, and most importantly, a place of wide range of opinions. These criteria are relative, since the earliest forms of mass media (the printed book or pamphlet) were limited to the minority of a society that happened to be ijc-journal@hotmail. com 20 literate and relatively close to the place of publication. There has been a continuous line of development of technologies since the earliest forms of media (rock paintings) to the latest digital forms that have expanded the capacity, speed and efficiency of transmission (McQuail, 2000). Meanwhile, as Block (1979) argues, mass media refers to methods of message transmission over space and time. Media involves a communication process by which messages are sent through space; both the ijcjournal@gmail. com Tilak Wijesundara International Journal of Communicology 2011;1(1) channels have come into existence and have been attracted by millions of listeners. Moreover, in India, Television made a humble debut when Doordarshan (DD) was initiated in 1959. Today, Television service is available throughout the country, directly as terrestrial TV and through cable operators, as satellite TV. When taking Films into consideration, India? s first Film was screened in 1896. Today, Indian Film industry which is widely known as â€Å"Bolliwood† is the largest Film industry in the world, producing over 800 Films annually. The present inquiry deals with variety of sub topics when analyzing Indian mass media. The coverage, popularity, diversification, westernization, commercialization, technology, entertainment, education, politics, sex, violence, women and children, are some of such topics which are deeply and sociologically analyzed in this regard. The print media, Radio, TV, and Films are taken into account as comprised of Indian mass media throughout the study. Having understood that the nature of mass media is determined by social conditions, a Himalayan attempt is made to understand Indian mass media as a manifestation of social implications prevalent in association with the society of India. It is due to this reason that a Sociological analysis is applied throughout the study as it bringsthe hidden realities of Indian society in general and its mass media in particular. Popularity Although it is evident that the overall popularity of mass media has been increasing, it is notable that this popularity varies in different media. In colonial India, print media had acquired an immense popularity among people as the vehicle of 21 sender and receiver devote time within that process (Hornic, Schlinger, 1981). So, in generally, as McQuail (2000) points out, it is not incorrect to denote the idea that the term „mass media? is shorthand to describe means of communication that operate on a large scale, reaching and involving virtually everyone in a society to a greater or lesser degree. It refers to a number of media that are now longestablished and familiar, such as newspapers, magazines, film, radio, television and the phonograph (recorded music). As historical factors indicate, oral exchange of news was the common method of communication in ancient India. As Malhan (1992) illustrates, religions and religious places (places of worship) employed every available medium of communication in that period. In addition, bathing places, tanks, riverbanks, sea shores, chopals also acted as forms of communication. It is also evident that educational institutions equally played a significant role in activating the process of communication in India in the past. The modern medium of communication system is seen to be originated in the land of India since the end of the eighteenth century. The print media came into existence at the end of the eighteenth century symbolizing the first modern medium of communication and information. Indian press today is one of the largest in the world with more than 30,000 Newspapers published with an annual circulation that exceeds 55 million copies. Meanwhile, it is true to state that India was among one of the earliest countries to adopt broadcasting. The cable subscriber base has increased from around 0. 05 million in the early 90s? to around 24 million by 1999-2000. Today, it is possible to view over 75 channels over satellite cable Television. In any case, as many studies do suggest, the prevalence of audio-visual media has not crippled the popularity of films. As Malhan (1992) suggests, even though TV and Video provide most of the ingredients within the home with all the comforts, people still prefer to see pictures on wider screens in crowded halls. In fact, Films provide the most direct communication to the mind and images do not need to be translated to be understood. It cuts language barriers and can be enjoyed by both the educated and the fool alike. The songs and dances in Films are immensely popular among masses and popular Film stars live in the hearts of common people for generations. What is interesting to see is that Western audiences are becoming more interested in Indian Films, which has made Indian Films a global phenomenon. Diversification The diversification has been a notable feature in Indian mass media. This symbolizes the diversity of India? s people. In 2001, India had 45,974 newspapers 22 independent movement and the voice of the people. Nevertheless, it is evident that this popularity shifted to Radio and TV with their emergence as audio-visual media, and this shift is significant after independence. Simultaneously, newspapers made a detachment of the general public. It is true that newspapers today have become a class medium. According to the present estimates, newspapers are purchased and read by less than 20% of India? s total population. Meanwhile, the broadcasting media have the capacity to reach out to the people in every four corners of the country. By indicating the popularity of Indian Radio, Malhan (1992) illustrates, â€Å"as a comparatively low cost spoken word medium, it has become a constant companion for farmers, workers, travelers, sports lovers and for all those who are interested in news, music, drama, quiz programs, farm bulletins, or views of eminent persons on public affairs. Because of its low cost and easy availability, it has been a common man? s paradise, and for people, a symbol of social respectability as well. However, it is incorrect to mention that the existence of print media has been totally paralyzed today, rather, evidence indicate that particularly the book publishing industry has been growing at an exceedingly higher level, with around 10,000 publishers and around 40,000 new titles every year. The domestic publishing market is in fact one of largest in the world today. Since its beginning, Television has acquired an immense popularity as the key media in the world. According to one idea, it is clear that Television is central to the processes of media saturation. Indeed, Television is central to modern society altogether (Abercrombie, 1997). The popularity of Television symbolizes the increase of ijc-journal@hotmail. com ijcjournal@gmail. com Tilak Wijesundara International Journal of Communicology 2011;1(1) large country where many languages are spoken. Each of the larger languages supports its own Film industry: Urdu/Hindi, Bengali, Marathi, Kannada, Tamil, Telugu, and Malayalam. Accordingly, the Indian film industry is placed in diverse regions as follows; ? ? ? ? ? ? ? The Hindi/Urdu film industry, based on Mumbai is called „Bollywood The Marathi film industry, based on Mumbai and Pune The Tamil film industry, based on Chennai, Tamilnadu The Bengali film industry, based on Kolkata, West Begall The kannada film industry, based on the state of Karnataka The Telugu film industry, Hyderabad, Andhra Pradesh based on including 5364 daily newspapers published in over 100 languages. The largest number of newspapers were published in Hindi (20,589), followed by English (7,596), Marathi (2,943), Urdu (2,906), Bengali (2,741), Gujarati (2,215), Tamil (2,119), Kannada (1,816), Malayalam (1,505), and Telugu (1,289). The diversification is also apparent in Indian Broadcasting media. For instance, All India Radio? s (AIR) programs have been diversified over the years. Today, its home service programs are transmitted for 3. 91 hours every year. In addition, there are also external service transmissions which present programs in 17 foreign languages and 8 Indian languages for over 56 hours daily. AIR broadcasts programs for special audiences and occasions. Specific programs are relayed for the armed forces, women and children, youth students, industrial workers, and rural and tribal people. Fourteen stations broadcast daily programs twice a week in regional languages for women with the objective of providing entertainment and imparting information on household topics. Programs on family welfare, a very important information sector for the welfare of the women are planned and produced by 36 family welfare units at various broadcasting networks. These programs are integrated with the general programs as well as those meant for special audiences like rural, folk, women, youth, and industrial workers (Malhan,1992). Indian Television has achieved an immense success in reaching wide range of viewers. The prevalence of over 75 channels itself indicates its veracity. Doordarshan (DD) alone offers diverse national, regional, and local service for Indian Television viewers. The diversification is immensely visible in association with Indian Films. India is a ijc-journal@hotmail. com The Malayalam film industry, based on the state of Kerala What all these factors suggest is that Indian mass media are highly diversified in order to access multitude of people. Commercialization/ Westernization In the present scenario, it has been often put forward the fact that Indian mass media are enormously subject to commercialization and Westernization. This is particularly true with regard to Television and Cinema. As D? Souza (1998) indicates, contemporary film making is a big financing venture more than ever before. It is usually controlled by commercial consideration rather than the demand o the art. Films make no demands on the power of thinking, rather, ignore it for the sake of commerce. This argument is supported by Malhan (1992) when he denotes the fact that the Cinema after independence is predominately commercial so far as feature films are concerned. 23 ijcjournal@gmail. com Tilak Wijesundara International Journal of Communicology 2011;1(1) advertisements or advertorials is disguised as news. Whatever it is, it can be assumed that the process of commercialization and westernization have been in a tremendous enhancement after 1990s than ever before, with the introduction of liberalization and privatization policies. Technology It is crystal clear that all the mainstream mass media in India are under the impact of high technological appliances. As Malhan (1992) indicates, the advanced technologies such as adaptation of satellite communication and broadcasting, electronic printing, electronic and digital technology, extensive use of Tele-communication, internet and computer machinery are enormously benefited by the print media today. Television and Radio too has no exception in this direction. Moreover, Indian Cinema is in extreme use of new and effective technology in the process of Film making, recording and screening. However, as D? Souza (1998) points out, even though India has been using an increasing level of technology, very powerful political and economic forces have gained control over technology in general and communication system in particular. This has obstructed the communication flow from and to the grass root level. What is indeed true is that Indian mass media today are in the hands of few business houses and companies. As Sahay et al (2006) remarks, the most visible change is the growing influence of commercial departments in the media companies in India.

Relationship between the three arms of government

The American government as a democratic government functions under the guidance of three government arms. The role of each arm of government is clearly spelt under the doctrine of power separation that sought to offer clear guidelines to allow the smooth and effective execution of government affairs. Bernas (1997) however claims that there are several government departments within these separate arms of government that have overlapping roles and that one certain issues it is hard to decide which arm the jurisdiction of such a controversial issue falls.However, it is argued that the founders of the nation sought to ensure the independence of all branches to ensure their supremacy in dealing with their particular spheres. However, it is necessary to note therefore that the functions of these arms of governments must adhere strictly to the constitution raising the question of who should be charged with the responsibility of enforcing those provisions. The executive arm of the government is fundamentally important to carry out the day to day running of the country. This power is usually vested upon the president and any person that the president deems fit to have power delegated to him.Therefore, the constitution mandates a duly elected president to appoint such individuals as he may see fit subject to the approval of congress. This paper in essence tries to focus on this relationship whereby a particular of the government is subject to the oversight of another in carrying out its duties. It therefore becomes necessary for the president to appoint such individuals as qualified to handle their respective duties and such individuals must hold high integrity for them to get the necessary legislative backing.The president enjoys immense powers under the constitution among which includes the responsibility of defending the constitution and protecting the United States from attacks. For this purpose it is important that his powers be subject to some form of oversight in order for it not to be misused to the detriment of ordinary Americans. The legislature is a basic necessity in any democratic nation and the United States is a pillar of freedom and hence the United States congress is the custodian of law formulation in the nation.The legislative wing consists of two separate houses expected to ensure effective and just formulation of laws to the benefit of society. The legislature is also charged with the responsibility of formulation laws regarding tax and authorizing various government expenditures. Furthermore the senate has complete authority to authorize the signing of treaties involving the nation bringing to the question of whether the executive has any true autonomous powers. It is also important to note at this juncture that it is not only congress that has influence on the executive but also the executive has considerable influence over the legislature.Most committee chairmen are appointed by party leaders, plus the fact the party leader also appoints a majority leader in congress to spear head party agendas in congress. In this regard the executive has considerable influence on the direction of congress even in ignoring the fact that the president has veto power over bills passed in congress. The other arm is the judiciary charged with the administration of justice based on equality, equity and integrity. The courts are the grounds through which conflicts are to be resolved and injustices either compensated or punished.In these solemn corridors of justice civil and criminal proceedings are initiated and the process of establishing guilt or innocence cleverly and impartially established. The court is also charged with the important duty of interpreting the constitution and establishing whether certain statues are constitutional or not. The appointment of judges is however left to the hands of the executive on the confirmation of the legislature. The judiciary is also charged with the duty to protect the rights and f reedoms of the American citizens against the exploitation of both the executive and the legislature.In this regard, the court is mandated to provide guidance and authority to the executive on the application of certain statutes that might infringe on the rights of the citizens. In this regard the court acts as the oversight authority on the excesses of the both the executive and the legislature by putting the interest of the citizens before all else. There are those who feel that oversight over government branches should be left to the masses. However, such a claim becomes rather untenable since there are no clear mechanisms to identify breach of constitution since most people lack the technical expertise to interpret the constitution.Furthermore, even when such a breach might be on the public domain there are no mechanisms for the public to stop legislation or the enforcement of the same. There fore, it becomes necessary to allow the court since it has been charged with matters per taining to the administration of justice and the upholding of the constitution. The court has the technical and legal mandate to interpret the constitution and therefore has the moral authority to rule on matters regarding the constitutionality of matters pertaining to changes or issues related to the constitution (Coxe, 2005).Opponents of the judicial power of review would seem to be lost in the fallacious belief that the authority of the judiciary to review legislations enacted by congress and senate as an interference of the role of the legislature. It can be argued if the status of other countries like the U K that bars courts from reviewing primary bills was to be taken into consideration that indeed the judiciary might have exceeded its jurisdiction. However, it is necessary and the constitution clearly stipulates that any law that is contrary to the constitution is null and void.Therefore, it is simply logical that the judiciary in exercising its role of constitutional interp retation make rulings on the constitutionality of bills passed by the legislative wing of government. This is because law makers might if no oversight exists make laws that are in their favor even if they are in contravention of the constitution. This is possible since the constitution might be subject to misinterpretation and due to its impartial nature, the judiciary can be trusted to enforce the provisions of constitution against the partisan interests of politicians.The status quo has not always been so since the various arms of government did not infringe on the operations of the other. The courts oversight on the constitutionality of legislations emanated from the ruling of the case, William Marbury v. James Madison, secretary of state of the United States. The court had ruled that Marbury’s petition to the court under the judicial act of 1789 to compel the secretary of sate to deliver his commissioning document was unconstitutional (Marshal, 1803). However, it is clear that since the three branches serve as one government, they cannot function without relating and providing oversight to each other.This creates accountability and checks against power abuse which might disadvantage the very people they are sworn in to serve. The legislator serves as an oversight against the executive and so the court must serve as and oversight on the legislature. Therefore, the present relation ship between the three branches is vital for the necessary functioning of the country and in the observance of the supremacy of our constitution. References Bernas, J.
