All [Woman and] Men Are Created Equal essays

All [Woman and] Men Are Created Equal essays It is disturbing to see that in society today I see as many unjust women as men. Most women have declared that women and men should have equal rights and I, as a woman, have to agree. However, many women today are abusing their rights for their benefit. What happened to equal rights? We may have equality in rights but we are not created equal, yet in some situations, e.g., in the workplace, many women lash out their anger and blame men. We are put on earth to do different things. We are built differently and we think differently. Naturally, women and men will have disagreements now and then. However, women must recognize that misusing their rights to take revenge for what men did in the past will not solve anything. Many women still believe that most men today view women as inferior, but when the fight for equality becomes distorted, women can be as sexist, prejudice and biased as men. Many men have subtly degraded women for many years. Its either that many women do not notice it or choose to look the other way. In the essay, Invisible Women, Yun Yung Choi explains how one man, Confucius, changed the lives of women for the worse in Korea. Choi states, Throughout the first half of Koryo period, which lasted from 918 to 1392, and throughout the Yi dynasty, women were important and contributing members of their society and not marginal and dependent as they later became. Women were, in large extent, in command of their own lives. She also states, With the introduction of Confucianism, however, the rights and privileges that women enjoyed were confiscated (187). In her essay, Choi quotes from Confucian proverbs such as Men are honored, but women are abased and A daughter is a robber women who carries household wealth away when she marries (187). Still today, many men have the same thoughts that Confucius had. I have worked with battered and ab...

Battle of North Point in the War of 1812

Battle of North Point in the War of 1812 The Battle of North Point was fought as the British attacked Baltimore, MD on September 12, 1814, during the War of 1812. As 1813 came to an end, the British started to shift their attention from the Napoleonic Wars to the conflict with the United States. This commenced with a surge in naval strength which saw the Royal Navy widen and tighten their full commercial blockade of the American coast. This crippled American commerce and led to inflation and shortages of goods. The American position continued to decline with the fall of Napoleon in March 1814. Though initially cheered by some in the United States, the implications of the French defeat soon became clear as the British were now freed to enlarge their military presence in North America. Having failed to capture Canada or compel the British to seek peace during the wars first two years, these new events put the Americans on the defensive and changed the conflict into one of national survival. To the Chesapeake As fighting continued along the Canadian border, the Royal Navy, led by Vice Admiral Sir Alexander Cochrane, mounted attacks along the American coast and endeavored to tighten the blockade. Already eager to inflict destruction on the United States, Cochrane was further encouraged in July 1814 after getting a letter from Lieutenant General Sir George Prevost. This asked him to help avenge the American burnings of several Canadian towns. To oversee these attacks, Cochrane turned to Rear Admiral George Cockburn who had spent much of 1813 raiding up and down the Chesapeake Bay. To support this mission, a brigade of Napoleonic veterans, commanded by Major General Robert Ross, was ordered to the region. On to Washington On August 15, Ross transports entered the Chesapeake and pushed up the bay to join with Cochrane and Cockburn. Assessing their options, the three men decided to attempt a strike on Washington DC. This combined force soon cornered Commodore Joshua Barneys gunboat flotilla in the Patuxent River. Moving up the river, they eliminated Barneys force and landed Rosss 3,400 men and 700 marines on August 19. In Washington, President James Madisons administration struggled to meet the threat. Unwilling to believe that the capital would be a target, little had been done in terms of preparing defenses. Overseeing the defense of Washington was Brigadier General William Winder, a political appointee from Baltimore who had been captured at the Battle of Stoney Creek in June 1813. As the bulk of the US Armys regulars were occupied in the north, Winder s force was largely comprised of militia. Meeting no resistance, Ross and Cockburn marched quickly from Benedict to Upper Marlborough. There the two elected to approach Washington from the northeast and cross the East Branch of the Potomac at Bladensburg. Following the defeat of American forces at the Battle of Bladensburg on August 24, they entered Washington and burned several government buildings. This done, British forces under Cochrane and Ross turned their attention north towards Baltimore. The British Plan A vital port city, Baltimore was believed by the British to be the base of many of the American privateers that were preying on their shipping. To take Baltimore, Ross and Cochrane planned a two-prong attack with the former landing at North Point and advancing overland, while the latter attacked Fort McHenry and the harbor defenses by water. Arriving in the Patapsco River, Ross landed 4,500 men at the tip of North Point on the morning of September 12, 1814. Anticipating Ross actions and needing more time to complete the citys defenses, the American commander at Baltimore, American Revolution veteran Major General Samuel Smith, dispatched 3,200 men and six cannon under Brigadier General John Stricker to delay the British advance. Marching to North Point, Stricker arrayed his men across Long Log Lane at a point where the peninsula narrowed. Marching north, Ross rode ahead with his advance guard. Armies Commanders: United States Major General Samuel SmithBrigadier General John Stricker3,200 men Britain Major General Robert RossColonel Arthur Brooke4,500 men The Americans Make a Stand Shortly after being warned about being too far forward by Rear Admiral George Cockburn, Ross party encountered a group of American skirmishers. Opening fire, the Americans critically wounded Ross in arm and chest before retreating. Placed on a cart to carry him back to the fleet, Ross died a short time later. With Ross dead, command devolved to Colonel Arthur Brooke. Pressing forward, Brookes men soon encountered Strickers line. Nearing, both sides exchanged musket and cannon fire for over an hour, with the British attempting flank the Americans. Around 4:00 PM, with the British getting better of the fight, Stricker ordered a deliberate retreat north and reformed his line near Bread and Cheese Creek. From this position Stricker waited for the next British assault, which never came. Having suffered over 300 casualties, Brooke elected not to pursue the Americans and ordered his men to camp on the battlefield. With his mission of delaying the British accomplished, Stricker and men retired to Baltimores defenses. The following day, Brooke conducted two demonstrations along the citys fortifications, but found them too strong to attack and halted his advance. Aftermath Impact In the fighting, the Americans lost 163 killed and wounded and 200 captured. British casualties numbered 46 killed and 273 wounded. While a tactical loss, the Battle of North Point proved to be a strategic victory for the Americans. The battle allowed Smith to complete his preparations for defending the city, which halted Brookes advance. Unable to penetrate the earthworks, Brooke was forced to await the outcome of Cochranes naval attack on Fort McHenry. Beginning at dusk on September 13, Cochranes bombardment of the fort failed, and Brooke was forced to withdraw his men back to the fleet.

Week 8 Discussion - Assignment Example However, jury nullification is not the solution of this problem as it weakens the legal system (Heffernan, 2012). If anything, jury nullification aggravates the problem by creating a distinction between people in the society on the basis of caste, color, or race, and thus fueling negative emotions of people belonging to one community against the people of the community whose crimes are nullified by the jury. I will not support the practice of jury nullification in any case regardless of the context or conditions. All human beings are equal and must be treated accordingly in the eyes of law. The law should be blind to the caste, color, race, or creed of the criminals and deal with every criminal in the same way. â€Å"The promotion of jury nullification rests on the assumption that 12 randomly chosen individuals are entitled to override the democratically expressed will of the citizenry† (Chicago Tribune, 2014). The fact that the black community is particularly disadvantaged in the society when it comes to accusations and arrests is a problem that is more deep-rooted than it appears at the surface. Apparently, it is the police that discriminates against the black community. In reality, the whole system of our society has been shaped up in such a way that people belonging to a certain community resort to crime and violence to get their rights. For example, the media frequently shows more blacks committing crimes in dramas and movies than the whites or other communities. So rather than going for such measures as jury nullification, it is more rational to bring a radical change in the society by removing the discriminating elements against the targeted communities at all levels. An arrest that is made without a conviction can have long-lasting disastrous effects on the life of the accused, thus jeopardizing their personal as well as social life. In 2011, the police in Brooklyn arrested a 26 years old single mother and forced her to show them the hidden marijuana

Roe v. Wade Essay Example | Topics and Well Written Essays - 1500 words

Roe v. Wade - Essay Example Justice Blackmun, writing for the majority, acknowledged that the state had an interest in regulating abortion as a way to reduce medical risk for women and to protect the lives of unborn children but argued that a woman’s right to terminate her pregnancy must be weighed against the rights of the state. As long as the fetus is not viable — the Court used an established definition of viability, which considered a fetus viable at the point it is able to live outside its mother, even if some artificial assistance is needed for it to do so — the state can only regulate abortions in ways that are reasonably related to maternal health. For abortions prior to the end of the first trimester, the Court held that the state should not interfere and should leave the decision-making to a pregnant woman and her doctor. Only for abortions during the third trimester of pregnancy, when the fetus is viable according to the Court’s definition, could the state prohibit aborti on and only then if doing so did not significantly threaten the health of the pregnant woman. Blackmun went on to state that in questions of abortion, there is no consideration of a fetus’s right to life under the protection of the Fourteenth Amendment because the Fourteenth Amendment protects only Americans who have been born. There is no Fourteenth Amendment protection for the unborn. Blackmon adds, in note perhaps to the spirit of the times, that the Court’s ruling is not intended to serve as an answer to the question of when life begins but only as a statement of the reach of the Fourteenth Amendment. Roe v. Wade remains a milestone case, setting the stage for countless arguments between those who support abortion and those who would do away with it. Though I agree with the gist of the Court’s decision — that a woman should be able to obtain a legal abortion, especially early in pregnancy — I find the legal basis for the Roe v. Wade decision a little shaky. Protecting the right to

Brief History of Microbiology 1- How Can Microbes Be Classified? Fungi, Protozoa, Algae, Prokaryotes and other organisms of importance to microbiologists B- The Golden Age of Microbiology 1- Is Spontaneous Generation Of Microbial Life Possible? Redis Experiment, Needhams Experiment, Spallanzanis Experiment, Pasteurs Experiment. CHAPTER (1): A BRIEF HISTORY OF MICROBIOLOGY Microbiology is the study of organisms and agents too small to be seen clearly by the naked eye. It is the study of microorganisms, or germs or microbes. However, some of these microorganisms are large and visible by our naked eye such as mushrooms, brown algae, and lichens. Viruses, bacteria, algae, fungi, and protozoa belong to microorganisms. Life would not exist without microorganisms. Plants depend on microorganisms to help them obtain their nitrogen they need from air. Animals such as cows and sheep need microorganisms in order to digest the cellulose in their diets. Our ecosystem rely on microorganisms to enrich soil, degrade wastes and supports life. Without microbial recyclers, the world would be buried under dead organisms. We use beneficial microorganisms to make our food such as cheese, yoghurt, bread, to develop our vaccines, hormones, vitamins and antibiotics. The human body is home to billions of microorganisms, many of which help keep us healthy. Microorganisms are not only an essential part of our lives; they are quite literally a part of us. Microorganisms can be both beneficial and harmful (infectious disease agents) to humans, animals and plants. Some harmful microorganisms also do cause diseases, from the common cold to AIDS. The threats of bioterrorism and new or re-merging infectious diseases are real problem. We will explore all the roles (both harmful and beneficial) that microorganisms play in our lives in this fascinating course. Importance of bacteria Bacteria can be categorized into harmful and useful bacteria, while some bacteria are non harmful-non useful. Harmful bacteria Bacteria cause some major diseases to humans, animals and plants. Among these diseases: cholera, typhoid, tetanus, pneumonia, tuberculosis and meningitis. Some pathogenic bacteria produce poisonous chemicals called toxins which affect certain parts of the host body. In food industry, bacteria cause spoilage of food and food poising. Useful bacteria Bacteria produce antibiotics which for the treatment of diseases. Bacteria provide enzymes for biological washing powders. Bacteria are used as microbial insecticides protecting crops from insect pests. Bacteria are used to leach out metals from some low grade ores such as copper and gold. Bacteria contribute greatly to food industry (butter, cheese, and yogurt). Certain bacteria are used to convert lactose (milk sugar) into lactic acid. Certain bacteria are used to convert alcohol into vinegar. Â  Bacteria have an essential role in the natural cycles of matter. In the soil, bacteria affect fertility, structure and productivity of corps. One of the most important roles of bacteria is the breakdown of dead organisms and organic wastes into its basic inorganic parts. Carbon dioxide, water, nitrogen, and sulfur are some of the most important materials returned to the soil and atmosphere. Such cycling of materials could not occur in the absence of certain bacteria. 9. As a source of food (single cell protein (SCP). Bacteria are a good source of (SCP) with plenty of food and space. (SCP can be produced using bacteria growing in waste paper, pollutants or any food waste product). The Early Years Of Microorganisms The early years of microbiology brought the first observations of microbial life, and the initial efforts to organize them into logical classification. Early investigators suspected the existence of microorganisms and their role in disease development even before microorganisms were detected. The first person observed and described microorganisms was Antony van Leeunwenhoek (The Father of Bacteriology and Protozoology) (Dutch) in 1674. He was a tailor and a lens grinder. He used to manufacture lenses to examine the quality of the clothes. He invented simple microscope in 1674 and he observed, drew, and measured large numbers of minute living organisms including bacteria and protozoa in pond water. He also described the motion, morphology and diversity of bacteria and protozoa. How Can Microbes Be Classified? Shortly after Leeunwenhoek made his discoveries, the Swedish botanist Linnaeus developed a taxonomic system-that is a system for naming plants and animals and grouping similar organisms together. Linnaeus and other scientists of that period grouped all organisms into either animal kingdom or the plant kingdom. Today biologists use the five kingdoms classification system and the three kingdoms classification system. The microorganisms that Leeunwenhoek described can be grouped into five basic categories: fungi, protozoa, algae, prokaryotes and small animals. The only microbes not described by Leeunwenhoek are viruses which are too small to be seen without an electron microscope. Cells are of two types: 1- Prokaryotic cells (pro = before, karyon = nut or kernel). Example: Bacteria (i) Organisms very simple in shape. (ii) The cells lack true membrane delimited nucleus. 2- Eukaryotic cells (Eu = true, karyon = nut or kernel). Examples: Algae, fungi, protozoa, higher plants and animals. (i) Morphologically more complex than prokaryotes and larger in size. (ii) Organisms with true nucleus. They have a membrane enclose nucleus. . Biologists have divided living organisms into five kingdoms: Kingdom Monera or Prokaryote: includes prokaryotic organisms (Bacteria and archea) and Cyanobacteria (the blue-green bacteria, formerly called blue-green algae). Kingdom Protista: Include either unicellular or colonial eukaryotic organisms that lack true tissues (Protozoa, small algae, and lower fungi). Kingdom Fungi: Includes eukaryotic organisms with absorptive nutrition and often multinucleate. Fungi includes moulds (filamentous fungi) and yeasts (unicellular fungi). Kingdom Animalia: Multicellular animals with ingestive nutrition (Vertebrates and invertebrates). Kingdom Plantae: Multicellular plants with walled eukaryotic cells and photosynthetic ability. Viruses do not fit into the classification of living organisms (five kingdoms classification system) because they are dependent on other cells for their reproduction (obligate parasites). Nevertheless viruses are also studied by microbiologists. The recent classification divided organisms into 3 kingdoms based on the analysis of the 16S RNA. Bacteria (True bacteria or Eubacteria). Archaea (Archaeobacteria). Eukarya (All eukaryotic organisms). Fungi (Mycology) Fungi are organisms whose cells are eukaryotic with a true nucleus surrounded by a nuclear membrane. Fungi differ from animals by having cell walls. Fungi are different from plants because they are heterotrophic (obtain their food from other organisms which is different from plants (obtain their food by themselves through photosynthesis i.e. autotrophic). Microscopic fungi include molds (filamentous fungi) and yeasts (unicellular fungi). Molds are multicellular organisms that are grow as long filaments called hyphae that intertwine to make up the body of the mold. Molds reproduce by sexual and asexual spores which produce new individuals. Yeasts are unicellular and they reproduce by budding. Many types of fungi are beneficial and some are also very harmful to humans causing many diseases. Mushroom is a typical example of macroscopic fungi. Some mushrooms are also poisonous and can cause death. Protozoa (Protozoology or Parasitology) Protozoa are single celled eukaryotic microorganisms with true nucleus that are similar to animals in their nutritional needs and cellular structure. The suffix protozoa in Greek mean (the first animals). Most protozoa are capable of locomotion through pseudopodia, cilia or flagella. Protozoa typically live freely in water, but some live inside animal hosts, where they can cause diseases. Most protozoa reproduce asexually, however some can reproduce sexually. Algae (Phycology) Algae are unicellular or multicellular photosynthetic autotrophic organisms. Algae are categorized on the basis of their pigmentation, storage products and their cell walls. Large algae commonly called seaweeds and kelps are common in the oceans. Unicellular algae are common in freshwater ponds, streams and lakes and in the oceans as well. They are the major food source of small aquatic and marine animals and provide most of the worlds oxygen as a by-product of photosynthesis. Prokaryotes (Bacteriology) Prokaryotic microorganisms are unicellular microbes that lack nuclei. There are two kinds of prokaryotes: true bacteria (Eu-bacteria) and archaea (Archaeobacteria). Bacterial cell walls are composed of a polysaccharide called peptidoglycan, although some bacteria lack cell walls. Bacteria without cell walls are called mycoplasma. The cell walls of archaea lack peptidoglycan and instead are composed of other polymers. Most bacteria and archaea are much smaller than the eukaryotic microorganisms. True bacteria are found in all environments, however, archaea are only found in extreme environments (Difficult or harsh environments) (e.g. High or low temperature, high or low pH, high salinity, high pressure). Other Organisms Of Importance To Microbiologists Microbiologists also study parasitic worms which range in size from microscopic forms to adult tapeworms over 7 meters in length. The only type of microbes that remained hidden from Leeunwenhoek and other early microbiologists are viruses, viroids and prions which are much smaller than the smallest prokaryotic microorganisms and are not visible by light microscopy. Viruses could not seen until the electron microscope was invented in 1932. All complete viruses are acellular (not composed of cells) obligatory parasites composed of small amounts of genetic material (genome) (RNA or DNA never both) surrounded by a protein coat. The incomplete virus (Prions) consists only of protein coat and there is no nucleic acid and only attacks human and animals. While the incomplete virus (Virioid) consists only of nucleic acid and there is no protein coat and only attacks plants. Leeunwenhoek fist reported the existence of microorganisms in 1674, but microbiology did not develop significantly as a field of study for almost two centuries. There were a number of reasons for this delay. First, Leeunwenhoek was a suspicious and secretive man. Though he built over than 400 microscopes, he never trained an apprentice, and he never sold or gave away a microscope. When Leeunwenhoek died, the secret of creating superior microscope was lost. It took almost 100 years for scientists to make microscopes of equivalent quality. Another reason that microbiology was slow to develop as a science is that scientists in the 1700s considered microbes to be curiosities of nature and in-significant to human affairs. But in the late 1800s, scientists began to adopt a new philosophy, one that demand experimental proof rather than mere acceptance of traditional knowledge. This fresh philosophical foundation, accompanied by improved microscopes, new laboratory techniques, and a drive to answer a series of important questions, propelled microbiology to the forefront as a scientific discipline. The Golden Age of Microbiology For about 50 years during what is now called The Golden Age of Microbiology, scientists were driven by the search for answers o the following 4 questions: Is spontaneous generation of microbial life possible? What causes fermentation? What causes diseases? How can we prevent infection and disease? Competition among scientists, who were striving to be the first to answer these questions, drove exploration and discovery in microbiology during the late 1800s and early 1900s. These scientists discoveries and the fields of study they initiated continue to shape the course of microbiological research today. 1 Is Spontaneous Generation Of Microbial Life Possible? In the ancient times, many peoples believed that living organisms could develop from non-living matter, and they named this phenomenon as spontaneous generation (abiogenesis). Aristotle believed that simple invertebrates could arise by spontaneous generation. He also believed that frogs and shrimps could arise from mud, insects from the morning dew and maggots from decaying meat. The validity of this theory came under challenge in the 17th century. Redis Experiment (1626-1697). The spontaneous generation conflict was finally challenged by the Redi (1688), who carried out a series of experiments using decayed meat and he studies the ability of meat to produce maggots spontaneously. He concluded that maggots do not arise by spontaneous generation. In unsealed flask: The maggots covered the meat within few days. In the sealed flasks: The flies were kept away and no maggots appeared on the meat. In the gauze-covered flask: The flies were kept away and no maggots appeared on the meat, although a few maggots appeared on the top of the gauze. Needhams Experiment (1713-1781). He boiled beef broth in a sealed flask. Some days later he demonstrated that many of these flasks became cloudy and contained microorganisms. He thought that the organic matter in the meat contained a vital force that could give the properties of life from non-living matter. Since he heated the flasks he thought that the microorganisms is coming from the non living beef broth. Spallanzanis Experiment (1729-1799). Spallanzanis in 1799 reported results that contradicted Needhams findings. Spallanzani boiled some infusions for one hour and sealed the vials by melting their slender necks closed. His infusion remained clear, unless he broke the seal and exposed the infusion to air, after which they became cloudy with microorganisms. He concluded three things: Needham had either failed to heat his vials sufficiently. Microorganisms exist in the air and can contaminate the experiments. Spontaneous generation of microorganisms does not occur. All living things arise from other living things. Criticisms of Spallanzanis work were: The sealed vials did not allow enough air for organisms to survive. The prolonged heating for long time (one hour) destroyed the Life force. The debate continued until the French chemist Louis Pasteur conducted experiments that finally solved the theory of spontaneous generation to rest. Pasteurs Experiment (1822-1895). In 1861, Pasteur (The Father of Microbiology) solved the spontaneous generation conflict. The Swan Neck Experiment Pasteur placed nutrient solutions in flasks heated their necks in a flame and drew them out in a variety of curved shapes, and he kept the ends of the neck open to the air. He then boiled the nutrient solutions for a few minutes and allowed them to cool. No microbial growth was observed; even the flask contents were exposed to the external air currents. Pasteur pointed out that no growth was observed because dust and germs had been collected on the walls of the curved pre-heated necks. If the necks were broken, microbial growth appeared. The results obtained by Pasteur were against the spontaneous generation theory. 2- What Causes Fermentation? Pasteur developed the pasteurization a process of heating the grape juice just enough to kill most contaminating bacteria without changing the juice backs qualities so it could then be inoculated with yeast to ensure that alcohol fermentation occurred. Pasteur thus began the field of industrial microbiology or biotechnology in which microbes are used to manufacture beneficial products. Today pasteurization is used routinely on milk to eliminate pathogenic bacteria that cause tuberculosis and is also used to eliminate pathogenic bacteria and fungi in juices and other beverages. Because of Pasteur many significant accomplishments in working with microbes, Pasture is considered the Father of Microbiology. 3- What Causes Diseases? Robert Koch (German Doctor) (the golden age of microbiology 1880-1920) was the first person to demonstrate the role of bacteria in causing anthrax disease in 1876. Kochs proof that Bacillus anthracis caused anthrax. Koch discovered that bacteria are responsible for causing a disease. This was called the germ theory of disease. The science of etiology (the study of causation of diseases) was dominated by Robert Koch. Koch established criteria for proving the causal relationship between a microorganism and a specific disease. These criteria are known as Koch postulates, and it can be summarized as follows: (i)- The organism should be constantly present in animals or plants suffering from the disease and should not be present in healthy individuals. (ii)- The organism must be cultivated in pure culture away from the animal or plant body. (iii)- Such a culture when inoculated into susceptible animals or plants should initiate the characteristic disease symptoms. (iv)- The organism should be re-isolated from these experimental animals or plants and cultured again in the laboratory, after which it should still be the same as the original organism. Koch also developed media suitable for the isolation of pure bacterial cultures from human body. He developed nutrient broth and nutrient agar media. In 1882 Koch has used these methods to isolate the bacteria that cause tuberculosis. During Kochs studies on bacterial pathogens, it became necessary to isolate suspected bacterial pathogens. At first, he cultured bacteria on sterile surfaces of cut, boiled potatoes. This was unsatisfactory because bacteria would not always grow well on potatoes because of the acidity of the potato tissues. He then tried to solidify regular liquid medium by adding gelatin. Separate bacterial colonies developed after the surface had been streaked with a bacterial sample. When the gelatin medium hardened, individual bacteria produced separate colonies. Despite its advantages, gelatin was not an ideal solidifying agent because it was digested by many bacteria and melted when the temperature rose above 28ÂÂÂ °C. Fannie Hesse suggested a better alternative. She suggested the use of agar as a solidifying agent. Agar is derived from red algae. Agar was not attacked by most bacteria and did not melt until reaching a temperature of 100ÂÂÂ °C unlike gelatin. Richard Petri developed the Petri dish (Plate) in 1887, a container for making solid culture media. This development made possible the isolation of pure cultures that contained only a single microorganism. Koch and his colleagues are also responsible for many other advances in laboratory microbiology, including the following: Simple staining techniques for bacterial cells and flagella. The first photomicrograph of bacteria. The first photograph of bacteria in diseased tissues. Techniques for estimating the number of bacteria in a solution based on the number of colonies that form after inoculation onto a solid surface. The use of steam to sterilize growth media. The use of Petri dishes to hold solid growth media. Aseptic laboratory techniques such as transferring bacteria between media using platinum wire that has been sterilized in a flame. Koch hypothesized that each bacterial colony consisted if the progeny of a single cell. Koch use laboratory animals to inject bacteria and study disease development. For these achievements, Koch is considered as the Father of the Microbiological laboratory. Grams stain Although Koch reported a simple staining technique in 1877, the Danish scientist Gram developed a more important staining method in 1884. His procedure which involves the application of series of dyes made some microbes blue and others red. The blue cells are called the Gram positive and the red cells are called the Gram negative. We now use Gram Stain to separate bacteria into these two large groups. The gram stain is still the most widely used staining technique. It is one of the first steps carried out in any laboratory where bacteria are being identified. 4 How Can We Prevent Infection And Disease? 1 Semmelweis and Hand washing Semmelweis was a physician began requiring medical students to wash hands with chlorinated lime water. 2 Listers Antiseptic Technique Joseph Lister (1867), an English surgeon found indirect evidence that microorganism were agents of human disease. He worked on the prevention of wound infection. He developed a system of antiseptic surgery designed to prevent microorganism from entering wounds. Instruments were heat sterilized and phenol was used on surgical dressings and sprayed over the surgical area. He provided a strong evidence for the role of microorganisms in disease development because phenol which killed bacteria also prevented wound infections. 3 Nightingale and Nursing Nightingale was an English nurse and she is the founder of modern nursing and she introduced cleanliness and antiseptic techniques into nursing practices. 4 Snow and Epidemiology John Snow an English physician plays a key role ion setting standards for good public hygiene to prevent the spread of infectious diseases. His study was the foundation for two branches of microbiology (infection control) and epidemiology (study of the occurrence, distribution and spread of disease in humans). 5 Jenners Vaccine On 1796, Edward Jenner used cowpox-infected material to successfully vaccinate people against human small pox. He names the process vaccination after Vaccinia, the virus that causes cowpox. Jenner invented vaccination or immunization. In honor of Jenners work with cowpox, Pasteur used the term vaccine to refer to all weakened protective strains of pathogens. 6 Ehrlichs magic bullets and Chemotherapy Ehrlich found that chemicals could be used to kill microorganisms. He discovered chemicals active against trypanosomes the protozoan that causes sleeping sickness and against Treponema that cause syphilis. His discoveries began the branch of chemotherapy. The Modern Age of Microbiology 1 How Do Genes work? Over the past 40 yeasts, advances in microbial genetics developed into several new disciplines that are among the faster growing areas of scientific research today; including: Molecular biology A Molecular Biology Molecular biology combines aspects of biochemistry, cell biology and genetics to explain cell function at the molecular level. Molecular biologists are concerned with genome sequencing. A full understating of the genomes of organisms will result in practical ways to limit disease, repair genetic defects and enhance agricultural yield. B Recombinant DNA technology Molecular Biology is applied in recombinant DNA technology, commonly called genetic engineering which was first developed using microbial models. This includes the production of human insulin in genetically engineered bacteria. C Gene therapy An exciting new area of study is the use of recombinant DNA technology for gene therapy. This is a process that involves inserting a missing gene or repairing a defective gene in human cells. This procedure uses harmless viruses to insert a desired gene into host cells where it is incorporated into a chromosome and begins to function normally. 2 What Roles Do Microorganisms Play in the Environment? The study of microorganisms in their natural environment is called environmental Microbiology or microbial ecology. 3 How We Defend Against Disease? Advancements in chemotherapy were made in the 1900s with the discovery of numerous substances such as penicillin and sulfa drugs that inhibit bacteria. 4 The Scope And Relevance of Microbiology Microbiology has both basic aspects and applied aspects. A scientist working in the field of microbiology is called a microbiologist. Many microbiologists are interested in the biology of microorganisms. They may focus on a specific group of microorganisms and are called: Virologist (Virology is the study of viruses), Bacteriologist (Bacteriology is the study of bacteria), Phycologist (Phycology is the study of algae), Mycologist (Mycology is the study of fungi), and Protozoologist (Protozoology is the study of protozoa). Other microbiologist work in other fields such as microbial physiology, microbial cytology, microbial ecology, and microbial taxonomy. Other microbiologists have more practical applied fields such as medical microbiology, food and dairy microbiology, and public health microbiology. Medical Microbiology: Deals with human and animal diseases. Agricultural Microbiology: Deals with the application of microorganisms in agriculture. Public health Microbiology: Deals with the control of the spread of diseases. Food and dairy Microbiology: Deals with the application of microorganisms by man to make foods such as cheese, bread, and other important products. Industrial Microbiology: Deals with the industrial application of microorganisms such as the production of vaccines, antibiotics, vitamins and enzymes. Microbial Ecology or Environmental microbiology: Deals with the relationship between microorganisms and their environments. Microbial physiology and Biochemistry: Deals with the study with physiology of microorganisms and the effects of physical and chemical agents on the survival of microorganisms. 6 What Will The Future Hold? What will microbiologists discover next? Among the questions for the next 50 years are the following: What is the physiology of life forms that can not be grown in laboratory and only known to us now by their nucleic acid sequences? Does life exist beyond planet Earth, and if so, what are its features? How can we reduce the threat of infectious diseases, especially those that can be used by bioterrorists?

Women in Bollywood

Film is somehow a depiction of real life. The movies produced reflect a nation’s culture and the interplay of its citizens within the society. Such interplay is the role of a man and a woman in India. Cinema in India is the largest productive movie industry in the world. Known as Bollywood, Indians are able to make films which portray the Indian’s way of life, promote their sense of identity, and their nationalism. By looking at Indian films, one can have the general idea of the Indian society. Women, in particular, are clearly portrayed in Bollywood.There are notions of what a ‘good’ and a ‘bad’ woman is. The actions of women depicted in the films also create norms on how women are placed in the society. Just like films from other countries, Bollywood have mostly projected women in a standardize character (Mishra, 2002, p. xix). Though the Indian culture evolves in accordance with modern times, women representation in films somehow has been ty pified within the norms. Two of the best-selling Hindi movies that made its mark on Bollywood Cinema have women as the main character.Mother India (1957) and Hum Aapke Hain Kaun (1994), both are notable works in the Indian film industry. The former being a dramatic movie and the latter, a romantic comedy combined with musical. These two films presented women who are bounded by the traditions of the society and how they reacted to it. Both of the films pertained to the concept of India’s ideal woman. As heroines from the two movies revolved around different environment and time frame, they were depicted as the women molded into the traditions of Indian society. These traditions lead to the films’ depiction of India’s nationalism.As what Thomas mentioned in her essay (1989) about India’s struggle for freedom in the form of films: Since it first emerged in the context of colonial India’s fight for independence, Indian cinema, for a number of reasons, has been concerned with constructing a notion of Indian cultural and national identity. This has involved drawing on concepts such as â€Å"traditions†. (p. 11) Mother India is a film that has a heavier plot than that of the Hum Aapke Hain Kaun. Radha, the female protagonist faced a lot of moral and social struggles as the story progress.Her personal role as a mother conflicted with her public responsibility as a woman. As a young woman who married the man she loves, she was encapsulated in the dutiful role of a wife. Radha fulfilled the traditional wife duties as her husband’s companion and helper at work. Radha is one of the most dynamic characters in Bollywood. Her change in attitudes in the course of the film was necessary as dramatic situations occurred in her story. The changes that happened in Radha’s character are two opposite personalities of a woman.From the shy, newly married young woman she transformed into a self-dependent single mother who worked h ard to uphold the dignity of her children and their standard of living. Her marriage with Shamu made her a committed and devoted wife to him. She is always at his side especially when working. However, as tragedy followed Shamu getting handicapped resulted into his decision to leave his family, Radha’s role as a mother has to be emphasized. Her timidity turned into a strong, courageous woman who built her family within dignified moral grounds.With this kind of dynamism, Radha was depicted as a powerful woman. The character of an empowered and independent woman was very rare in Indian cinema at the time Mother India was released. This kind of portrayal brought Radha with goddess-like features because of enduring so much struggles and overcoming tribulations. Radha was one of the few fictional female characters depicted in a heroic manner. The flow of Radha’s story is quite similar with the goddess Sita. Radha who endured the hard work together with her husband just like what Sita did when she gave up richness to join her husband in exile.Both of them endured the hardships of raising their children alone. Though both of them may have been portrayed as frail and timid, they exude strength especially in the most challenging aspect of their lives. The loyalty and chastity of the goddess can be seen on the scene where Radha refused Sukhilal’s offer of marriage. Upholding her chastity meant maintaining the dignity of their family despite their situation of poverty. Radha always reminded her sons to live a life within moral principles and to serve as good citizens of their village.The chastity was not only for her but for her family’s name. Her sons became the extension of maintaining that purity despite their strife in life. Another goddess associated with Radha is the goddess Kali. The goddess is described as the â€Å"fierce, passionate goddess of both life and destruction† (Thorner, Raj & Trust, 2000, p. 97). The fierceness of th e goddess can be witnessed when Radha aggressively declined Sukhilal’s seduction and almost caused havoc inside his house. The characteristic of Kali’s destruction can be identified in the event when Radha shot her favorite son.There was a struggle within Radha to be a good mother or to be a law abiding citizen. Birju failed to uphold what his mother have instilled to them and because of this, Radha decided to end his life to maintain the honor of the family. The association of Radha with Kali has been further justified by Rosie Thomas. Focusing on the experiences of men closer to Radha, Thomas indicated Radha’s goddess feature of punishment. Her depiction on the film holding heavy axe and shovel that she uses for farm work portrayed her as a strong woman that is capable of punishing if things does not go right (Thomas, 1989, p.17). The mere association of men with Radha caused the men on the film to be somewhat destroyed. Thomas described this destruction as an attribute to Radha being compared to Kali: She kills her favorite son; her husband loses both arms (and implicitly his manliness)†¦the villainous Sukhilal end up covered in cotton fluff, cowering like a naughty infant as she beats him with a big stick†¦Thus, she is both venerator of men and venerated by them as devi (goddess) and maa (mother), and she is, in turn, in need of men’s protection and a protector and destroyer of men. (p.16) The character of Radha can be quite the contrary for the depiction of Nisha in Hum Aapke Hain Kaun. This is a romantic comedy family-oriented film. If Mother India mostly portrayed the role of the woman in a society, Hum Aapke Hain Kaun showed women’s place within the structure of the family. Indian traditions are clearly emphasized on the film especially in the engagement and wedding ceremonies (Hirji, 2005). Though the plot in the movie consists of light drama, the underlying role of the women in a typical Indian family conn otes how women are in real life.The women in this film are bounded by family traditions which meant that every decision in the family should come from the male member of the family. The arrangement that was made between Mr. Kailashnath and Mr. Siddharth for Pooja and Rajesh’s wedding made it very clear. This scene proved that family decisions should rule and the rule comes mostly from the male members. Women in Hum Aapke Hain Kaun are portrayed as dutiful and obedient. Nisha, the younger sister of Pooja, is the woman who is given focus on the film. She is portrayed in the film as a playful prankster and cheerful woman.As every woman in India, she is deeply attached with her family and it is seen in her relationship with her sister whom she’s closest with. Eventually, Nisha’s relationship with Prem will be greatly affected by her relationship with her family. Like Radha, Nisha experienced a transition within her character. Though Radha is a bit more complex, Nish a’s transition can be seen from being a happy-go-lucky girl to a woman that has to fulfill her family’s traditions. This is more evident when Prem and Nisha sacrificed their love so that she could marry Prem’s brother after Pooja’s death.The woman is seen to give up her own wishes and desires to abide her duties in her family. This aspect of women in Indian culture provided similarities with the goddess that was compared with Mother India. Aside from being loyal and upholding her chastity, the goddess Sita is a devoted and dutiful woman to her sons and to her husband. This feature is apparent on the easy acceptance of Pooja with the arrangement of marriage with Rajesh. The marriage was arranged by two of the highest male authorities of both families and the film portrayed that the decision to marry was a final thing to do.Shedding off whatever attraction that may have happened when they were introduced, an objection for the marriage from either Pooja or R ajesh did not exist for the sake of their fathers. On the other hand, Nisha – despite her feelings for Prem – decided to marry Rajesh for the sake of her nephew and her dead sister. Though it was against her will, she decided to take the route of being married to her brother-in-law. This event, as part of her change, showed Nisha becoming an ideal woman who sacrificed and obeyed her family.Like the goddess Sita who allowed Rama to exile her, Nisha complied with her family’s request even if it entailed to give up her love for Prem. This film showed the Indian traditions viewing Nisha as a heroine who â€Å"would never put her own dreams ahead of the aspirations and desires of her family or men† (Ghose, 2006, p. 5). The conservative woman who considers her self as a second priority is what appeal as an ideal woman. Nisha is a good woman with a generous heart that can be compared to the dutiful goddess Sita who is the epitome of how Indian women are raised.O n the contrary, the opposite of the good or ideal woman is revealed in the character of Mamiji. Nisha is portrayed as the simple conservative girl while Mamiji is depicted as â€Å"selfish, mercenary, and vain† (Ghosh, 2000, p. 86). Her being vain is symbolized as being self-centered which opposed Nisha’s character of selflessness. The fact that Mamiji does not have a child of her own makes her what she is. The lack of motherhood in her personality diverted her attention solely on herself. The concept of a ‘bad woman’ in the film can be compared to the struggle that India has been experiencing after the colonial period.Somehow, the qualities of a ‘bad woman’ in the image of Mamiji such as going to the beauty parlor can be seen as a modern type of woman. As Rosie Thomas mentioned, Indian films are mostly in the context of struggling for independence by showcasing nationalism through tradition (Thomas, 1989, p. 11). The depiction of the scheming Mamiji as a modern woman in oppose to Nisha or Pooja as the traditional women of India; say much about India’s effort to promote its culture rather than the practices that are left by their invaders.Taking all of these into account, somehow it can be determined that an ideal woman within the Indian society is someone who is submissive and selfless. Both films are able to portray those traits. Mother India and Hum Aapke Hain Kaun are perfect depictions of women who are bounded by Indian traditions whether in society or in the family. Though both women differ in strength and with the way they are portrayed, Radha and Nisha are both subjected to the responsibilities that they have as women leaving no room for their own will and personal desires.The portrayal of women in films having goddess-like characteristics, symbolizes the nationalism of India. India regarded many female gods in their religion and they attributed these deities as an example of how a female should behave in the society. Emphasizing traditions in Bollywood is their way of promoting Indian nationalism. One effective way of showing these traditions would be in the form of a female as both of these films have been considered as icons in the Indian film industry.These female characters that were associated with Hindu goddesses transcend into society to be emulated and to uphold the culture. For Indians compare their country to a female that nurture its people and unselfishly gave her land for them to nourish and to raise a dignified India. References Ghose, A. (2006).
