Feminism

The theory o feminism seeks to give women justice in a patriarchal society. Since the male figure is domineering over the females or otherwise, this theory aims to end sexism in all forms. It is the belief that women should be protected with their rights and that men and women are equal, only different with the rights they stand up for. Also, in the literary arts, women are equally powerful to men in terms of rights, professions and capabilities. Feminism aims to remove the stereotyped concept of women being weak, submissive and dependent.

Women in the middle ages were completely dominated by males and were expected to obey them, their fathers, brothers, other male members of the family but then loyalty shifts to her husband when she marries. Unruly behaviour of women is considered a crime to their belief. They as well have in their culture the idea called Primogeniture. It is the custom that the first male child will inherit the wealth and/or titles of the family, women, does not inherit these. Though after marriage, women lose all their legal rights, for example, to own a property or to sign contracts. They believe in the existence of a universal hierarchy where God is the supreme, followed by the angels and then the males. They were also not educated well and were impeded to most professions; they were bound to the confines of home yet are rarely given custody over their children. But a great leap for women climaxed when Elizabeth I was made queen of England which defied the status of women and the believed universal hierarchy.

Here are some movements or steps those generations of women pushed through or acted on to protect their rights:

· “1st WAVE FEMINISM”

o 19th-20th : women in the United States and the United Kingdom fought for women’s SUFFRAGE (right to vote )

o Elizabeth Cady Staton & Susan B. Anthony fought to abolish slavery in the U.S

o Most feminists belonged to conservative Christian groups; others to more radical movements

· “2nd WAVE FEMINSM”

o Fought for the end of discrimination

· “3rd WAVE FEMINISM”

o Early 1990’s

o Also fought against RACIAL DISCRIMINATION

o Feminists came from diff. races, classes, cultures and genders

Feminism in Hamlet: Contrasting Views

Ophelia

She could not decide for herself for instance, she is very much dependent to her father, Polonius; when she was asked for her to participate with the spying on Hamlet. Another is when she lost her sanity for the reason of her father’s death and/or Hamlet’s betrayal. She is weak. While the conflicting messages from these male/masculine sources damage Ophelia’s psychological identity, their sudden absence provokes her mental destruction. Optimistically, Ophelia’s madness offers the capability of speech, the opportunity to discover individual identity, and the power to verbally undermine authority. A thorough analysis of Ophelia’s mad ramblings (and their mutual levels of meaning) provides a single exposé of society, of the turbulent reality beneath its surface the appearance of calmness. And her words still suggest a split self and provide others the opportunity to control meanings that best suit them.

Gertrude

l Gets involved in what is happening around her

l Maintains upper hand with Hamlet

>Is concerned with Hamlet’s condition; not afraid to question Hamlet

Near DEATH-> refuses to heed husband in drinking the poisoned chalice

Dies prominent male characters

Weak

Got married after King Hamlet died

FEMINISM / GERTRUDE / PSYCHOANALYTIC

Concurring with “Lacan’s notions of the phallus, jouissance, the symbolic, the imaginary, and the signifying chain” (140), this article suggests that Gertrude demonstrates “the way woman’s complicity is essential to the patriarchal order as she provides a glimpse of a woman who steps outside its parameters” (141). In the role of mourning, woman represents “the invisible medium through whom the phallus passes” (144). But Gertrude substitutes “marriage nuptials for mourning rituals”; her marriage to Claudius “violates the father who has not been properly remembered, and it violates the son who is denied his legacy” (146). Gertrude’s “refusal to mourn brings back the ghost and fuels its impossible request: that the son do what the mother will not, legitimize the father” (146). But Hamlet, a male bound by patriarchal laws, cannot perform the “social act” of mourning, as he and Laertes prove at Ophelia’s burial (141). And, as long as Gertrude “confers legitimacy on Claudius, Hamlet’s action is barred” (149). The son begins the process of “re-inserting his mother into the patriarchal phallic order” in the closet scene by accusing her “of being too old to love,” by de-legitimizing her “mode of otherness” (149). Gertrude, in death, finally frees Hamlet to act by being unable to mourn Claudius, but her absence means no mourning and, hence, no mediation for the transference of power: “in the absence of women, Denmark comes under the rule of its enemy,” Fortinbras (151-52). “Rejecting the role of passive mediator Gertrude plays the game of jouissance” (153). Yes, Gertrude is destroyed as a result, but she succeeds “in exposing the myth of the male phallus” and “provides us with a glimpse of a signifier placed outside the patriarchal structure of silenced mourning women” (153).

World Jewish leaders meet with pope, discuss anti-Semitism

By Cindy Wooden
Catholic News Service

VATICAN CITY (CNS) -- Pope Benedict XVI welcomed the new leaders of the World Jewish Congress to the Vatican.

Ronald S. Lauder, elected president of the congress in June, said his talks at the Vatican Oct. 8 focused on interreligious dialogue and on anti-Semitism in a number of European countries.

While the congress issued a press release after the meeting, the Vatican simply announced that the pope had met the officers of the congress, which represents Jewish communities in more than 80 countries.

The congress' statement said Lauder, a former U.S. ambassador to Austria, told the pope that "the anti-Semitic statements" attributed to Redemptorist Father Tadeusz Rydzyk, founder and director of Poland's Radio Maryja, "should not be tolerated anymore."

Lauder "called on the pontiff to take action against those in the church who wanted to do damage to the close and positive relationship between Christians and Jews," the statement said.

Father Rydzyk, whose radio station ranks fifth in Poland's national ratings, repeatedly has been accused of making anti-Semitic remarks.

When Lauder and the organization's secretary-general, Michael Schneider, met the pope, they also highlighted the importance of dialogue among Christians, Jews and Muslims.

At a dinner with Vatican officials, diplomats and representatives of Italy's Jewish communities Oct. 7, Schneider said that with "their credo of death and destruction" a radical Muslim minority has been intimidating the Muslim majority.

"Fanatics seek no less than the complete destruction of our Western Judeo-Christian civilization, yet the majority of Muslims do not support Islamic fanaticism," he said. "Most Muslims are decent, law-abiding people. They have the same aspirations as we do for their families and for their future."

Christians and Jews, he said, must reach out to the Muslim majority and build "bridges of tolerance and understanding."

The press statement also said Lauder "offered to host a joint event in honor of the pope during the pontiff's forthcoming visit to the United States."

The congress has headquarters in New York, which is reported to be on the pope's itinerary for a spring 2008 trip.

"The pope accepted the invitation in principle and said that both sides should work on the arrangements," the congress said.

You think about Kim, you think about rock ‘n’ roll. And she’s anything but the mild, mediocre wannabe. In fact, it would be just short of exact to associate her with the terms music and revolutionary.

An undeniable free spirit who measures the world with every stride she makes in it, she really doesn’t let it define her move than she makes sure she defines it. Ever the party enthusiast, Kim is the person you don’t leave behind trips to worlds that are untouched by the uptight and the boring. She’s the one you hire as captain.

Soccer baby, crooner, a dance partner who wouldn’t hold back on riveting tangos and the person you depend on to revive the dead, Kim is someone you pocket at the end of year, because if you don’t, a life ahead filled with persistent gaps of nothingness and the sound of monotony will certainly loom close behind.

Diocese of Rome says sale of relics is sacrilegious

By John Thavis
Catholic News Service

VATICAN CITY (CNS) -- The Diocese of Rome has underlined that the sale of relics is sacrilegious, following media reports that bits of garments worn by Pope John Paul II were being sold online.

The Rome diocesan office charged with promoting Pope John Paul's sainthood cause has been distributing prayer cards and relics, tiny pieces of one of the white cassocks worn by the late pope.

The cards and relics are offered free of charge to those requesting them, but the office has sometimes encouraged donations for postage. More recently, its Web site ran a more general invitation to make a "free-will offering for the cause."

That apparently caused enough confusion to spur press reports of the sale of relics.

In late September, the diocesan Web site posted interviews with church officials emphasizing that the relics were not for sale and never have been.

"Relics absolutely cannot be bought or sold because they are sacred objects, they have no price. The problem of the sale of relics is widespread on the Internet, and let me say that this is a sacrilege," Msgr. Marco Frisina, who heads the liturgy office in the Diocese of Rome, said in one of the interviews.

A boxed announcement across the site now states: "The holy card is completely free. It is possible for those with the means to make a free-will offering to support the cost of printing and mailing the cards."

Msgr. Frisina also responded to those who wondered whether distributing relics of the late pope implied a premature judgment on his sainthood cause.

Pope John Paul, he said, was venerated and held in great affection by many people while he was living, and "the holy card with a piece of his cassock for now we can use in a private way, as a remembrance of a loved one."

"We need to always be prudent and have much patience, obeying the church and waiting for the church itself to proclaim him a saint," Msgr. Frisina said.

The Diocese of Rome's English-language site dedicated to the sainthood cause of Pope John Paul is http://www.vicariatusurbis.org/Beatificazione/English/HomePage.htm.

Three Cheers for Coffee

I hate how coffee turns into an addiction and how it keeps you up all night.
how it burns and makes your heart beat fast.

especially how it makes you crave for its rich and sweet promises of grains, milk and sugar.

Moments later, it puts you into a melancholic mood of coldness, before you realize, it has consumed you before you should have consumed it.

Empty.
Hollow.
Bitter.


Then again you crave for another cup.

By Carol Glatz
Catholic News Service

VATICAN CITY (CNS) -- Young children must be guided from a very early age with moral law so that they will have direction as they weather life's storms and resist its temptations, Pope Benedict XVI said.

"God's law must be impressed on the soul from the beginning 'like on a piece of wax,'" the pope said, citing the teachings of St. John Chrysostom at his Sept. 19 weekly general audience.

Early infancy "is in fact the age that is the most important" because it marks the time when "the great directives that point to the right course to (take in) life" really take hold in a person, he said.

Pope Benedict returned briefly to the Vatican from his papal summer villa south of Rome for the weekly audience in St. Peter's Square.

The pope dedicated his talk to the life and writings of St. John Chrysostom, the fourth-century doctor of the church and archbishop of Constantinople, now Istanbul, Turkey. The 1,600th anniversary of his death is being celebrated this year.

The saint saw that humanity must strive to first accurately know "true doctrine" and then translate it into one's own life by following moral principles and virtues, the pope said.

He said St. John Chrysostom urged people to provide children early on with the "spiritual weapons" they would need to protect themselves later during adolescence and the teen years from "the violent winds" of lust and other strong desires.

Aided by the virtue of temperance and a solid Christian formation, "well-prepared married couples thus block off the road to divorce," he said.

Everything in life will unfold "with joy and (parents) can teach their children the virtues," the pope said.

With the birth of a child, "the three become just one flesh" as the child is the bridge that connects the two parents creating "a tiny church" -- a domestic church, he said, quoting St. John Chrysostom.

St. John Chrysostom also reminded the lay faithful that they are responsible for the salvation of others, the pope said.

St. John Chrysostom said that as social beings people are not meant to just be interested in themselves, said the pope. Through baptism, every Christian becomes "king, priest, and prophet" who is responsible for bringing the truth of Christ to the world, the pope said.

Among the 15,000 faithful gathered in the square were Cardinal Sean P. O'Malley of Boston and Greek Orthodox Metropolitan Methodios of Boston. The two leaders were heading a 100-member Catholic-Orthodox ecumenical pilgrimage from the United States to Rome, then Istanbul, Turkey, and ending in St. Petersburg, Russia.

St. John Chrysostom, whose Western feast day was Sept. 13, led the church of Constantinople before the split between the Christian East and West and is venerated as a doctor of the church by Catholics and Orthodox.

On Guiding Children with God’s Law

On the article:

Children brought up by faith would have a stronger character. It would have a rational perspective in life that the chances of being led to sinful or unaccepted ways in our society would be minimal. I also believe that education is very much important together with these factors. If a child is not properly educated by his parents through the virtues that we live as Christians, the child will more likely be stray away from our beloved Father.

A child brought up well and with the teachings of the Lord in mind, a strong, faithful Christian is at hand. Our society will have fewer problems and would be community-centered and very much giving to each and everyone. There would be peace in the community centered in the Father’s teachings and the children would grow up to have fear with the Lord, which is, in that case, very vital in ones morality.

  1. What is price elasticity of demand? When is demand elastic? Inelastic?

Price elasticity of demand is the reaction due to a change in price verified by its coefficient which is the percentage demand change in quantity demanded divided by the percentage change in the price.

A demand is said to be elastic if the percentage change in the quantity go beyond the percentage change in price, and the quantity demanded is receptive to the difference in price. In contrast, a demand is said to be inelastic if the quantity demanded is not that reactive to the adjustments or changes in prices. Which mean that the percentage change is quantity is less than the percentage change in price.

  1. Give two factors that determine price elasticity of demand.

The two factors which determine price elasticity of demand is the availability of substitutes and the number of uses to which a piece of merchandise may be applied. The demand fir the commodity, services, good or product, with more uses is more elastic than the demand for commodities with less function or use.

  1. Differentiate a perfectly elastic curve from a perfectly inelastic one.

A perfectly elastic curve if drawn as a horizontal line and being that the price does not change in any quantity. While a perfectly inelastic demand is when the quantity demanded is fixed for all alternative prices. Its demand curve is drawn as a vertical line.

The Joly Photometer: Measuring Light Intensity Using the Inverse Square Law

Objective

The goal of this project is to measure the relative intensity of different light bulbs, using a simple photometer that you can build yourself.

Introduction

PhotoAs you move away from a light source, the light gets dimmer. No doubt you've noticed this with reading lamps, streetlights, and so on. The diagram at right shows what is happening with a picture. At the center, the yellow star represents a point source of light. Imagine the light from the star spreading out into empty space in all directions. Now imagine the light that falls on a square at some arbitrary distance from the star (d = 1, yellow square). Move away, doubling the distance from the star (d = 2). The light from the original square has now "spread out" over an area of 4 (= 22) squares. Thus, at twice the original distance, the intensity of the light passing through a single square will be 1/4 of the original intensity. Going out still further, tripling the original distance (d = 3), and the light from the original square now covers an area of 9 (= 32) squares. Thus, at three times the original distance, the intensity of the light passing through a single square will be 1/9 of the original intensity. This is what is meant by the "Inverse Square Law." As you move away from a point light source, the intensity of the light is proportional to 1/d2, the inverse square of the distance. Because the same geometry applies to many other physical phenomena (sound, gravity, electrostatic interactions), the inverse square law has significance for many problems in physics.

In this project you'll build a simple photometer, invented by the Irish scientist, John Joly. As you'll see, the design of the photometer is based on the inverse square law. In the Joly photometer, two equal-sized blocks of paraffin wax are separated by a layer of aluminum foil. The wax blocks are mounted in a box with windows cut out on the left, front, and right sides, as shown in Figure 1.

mount the wax blocks in a small cardboard box with windows cut in the left, front, and right sides

Figure 1. Diagram of a Joly photometer. Inside the box are two equal-sized blocks of paraffin wax, separated by a sheet of aluminum foil.

The photometer is positioned between two light sources (see Figure 2). The two light sources and the center of the photometer should all be at the same height. Light from the first source illuminates the left-hand paraffin block. Light from the second source illuminates the right-hand paraffin block. To insure uniform illumination, the distance from each light source to the photometer should be relatively large compared to the size of the wax block. Also, there should be no other light sources in the room. The experimenter views the photometer through the front window and moves it back and forth between the two light sources until both blocks appear equally bright. The photometer should be moved along an imaginary straight line connecting the two light sources.

Figure 2. schematic diagram of Joly photometer experimental setup. See text for details.

When the two wax blocks are equally illuminated, the relationship between the intensities of the two light sources is determined by the inverse square law. Here is the relationship in the form of an equation:

inverse square law relation between the intensities of the two light sources

You can build your own Joly photometer and use it to measure the relative intensity of different light bulbs. Using the wattage of each bulb, you can also compare how efficient different bulbs are at producing light.

Terms, Concepts and Questions to Start Background Research

To do this project, you should do research that enables you to understand the following terms and concepts:

  • inverse square law,
  • incandescent light bulbs,
  • compact fluorescent light bulbs,
  • photometer.

Questions

  • How do incandescent light bulbs work?
  • How do incandescent light bulbs wear out?
  • How do compact fluorescent light bulbs work?
  • How do incandescent light bulbs wear out?
  • Which type of bulb lasts longer?
  • Which type of bulb is more efficient at producing light?

Bibliography

Materials and Equipment

To do this experiment you will need the following materials and equipment:

  • 1 lb. box of paraffin wax (contains 4 slabs),
  • sharp knife for cutting wax,
  • aluminum foil,
  • small cardboard box,
  • scissors,
  • two identical light fixtures (e.g., clamp-on work lamp),
  • measuring tape,
  • various light bulbs to test.

Experimental Procedure

Building the Photometer

  1. You should be able to find one-pound boxes of paraffin wax at your local grocery or hardware store. Each box contains four slabs of paraffin wax.
  2. Cut one slab of the wax in half with a sharp knife. Work carefully so that you don't chip or break the slab.

schematic diagram of Joly photometer experimental setup

  1. Place the photometer in between two light sources.
    1. Each wax block is illuminated by only one of the sources. The aluminum foil prevents light from passing between the blocks.
    2. The light sources and the photometer should be at the same height.
    3. The photometer should be positioned on the straight line between the two sources.
    4. The two light sources should be the only sources of light in the room. No bright sunlight!
    5. To insure uniformity of illumination at the photometer, the distance from the photometer to the nearest light source should be large compared to the size of the wax block.
  2. Move the photometer back and forth between the two light sources until the the two wax blocks are equally bright.

Analyzing Your Results

  1. When the wax blocks are equally illuminated, the inverse square law says that the intensities of the two light sources are related by the following equation:

inverse square law relation between the intensities of the two light sources

  1. Choose one light bulb as your standard, for example, a 60 W soft white bulb. Call this light I1. The intensity of the second light is then given by:

calculating the relative intensity of the second light source

  1. Measure the distance from each light source to the aluminum foil layer of the Joly photometer.
  2. Calculate the relative intensity of each bulb compared to your standard bulb. (Your standard bulb will have an intensity of 1.0. You can check this by using two identical bulbs. It's a good way to show that your photometer works as expected.)
  3. To calculate the efficiency of each bulb, divide the relative intensity by the bulb wattage.

Variations

  • Compare the output of incandescent vs. compact fluorescent bulbs. Using your measurements, can you figure out how to compare the cost of using each type of bulb in order to provide an equal amount of light? Your cost comparision should include the cost to purchase each bulb, the cost of electricity for each bulb, and the lifetime of each bulb.
  • Compare the output of "long-life" bulbs vs. normal incandescent bulbs. Many long-life bulbs are designed to run at higher voltage (e.g., 130 V) than is normally supplied from the wall socket (115 V in the U.S.). When run at normal house voltage, these bulbs do not get as hot as they would at 130 V, which means that they last longer. You can use your photoometer to find out what effect the lower voltage has on the light output for these bulbs. Are they more or less efficient than normal bulbs?

Physical and Human Resources

What are Physical Resources?
§Definition: Man-made structures and equipment constructed to increase the productive capacity of the economy

§Main features:

  • §Since they are man-made, they can be increased through the process of capital formation or investment.
  • §Capital formation involves both the creation of new structures and equipment that will make it possible to replace old structures which have lost their productive capacity. Repairs and maintenance are not part of capital formation.
  • §In time, physical resources lose their productive capacity through depreciation, which is the process of normal wear and tear of a physical capital.

§Main components:
  • §Buildings for residential, commercial, industrial and social (health and education) purposes
  • §Roads
  • §Bridges
  • §Power plants to generate electricity
  • §Irrigation and water supply plants
  • §Commercial and industrial machinery and equipment

§Effects on the economy:
  • §A general measure of capital accumulation is included in the national income accounts, including among its components, the construction of buildings, plants, and other structures and the purchase of durable equipment.
  • §Housing services, office space and individual plants are provided by the construction of buildings by the government and private sectors. Local governments have added more public buildings and educational buildings to the stock of physical capital than the private sector. Public spending can thus lead to economic growth.
  • §Roads and bridges facilitate the movement of people and goods, thereby increasing the rate of urbanization.
  • §Power plants that generate electricity and irrigation facilities that provide water to farmers are physical resources, too. They can affect the economy indirectly through the outputs of manufacturing and agriculture.

What are human resources?
§Definition: This is derived from the power of humans to produce goods and services. Traditionally, this is defined as labor, meaning the physical exertion of muscle to produce labor.

§Main features
  • §Although the population is an indicator of human resource in the country, it is a crude measure of human resources.
  • §The quality of the population in terms of state of health, nutrition, age and education is a more appropriate measure of a nation’s human wealth.
  • §One’s education and training makes one productive. Hence, training and education are treated as expenditures in human capital formation, similar to investment in physical capital. Both investments increase and improve the productive capacity of the nation. Health and nutrition are also investments in human capital since they increase the productivity of persons. A dead person is the least productive of the human resources.

§Main components
  • §Labor force: The men and women from age 15 and above who are fully employed , partially employed or looking for work. Human resources are the capable and old enough individuals who have the minimal physical strength to be employed to produce commodities and services.
  • §Excluded in the labor force are individuals who opted not to engage in economic production. These include students, housewives, the physically handicapped, the mentally challenged, and the aged.
  • §Labor force participation rate: the proportion of individuals in the labor force to the potentially economically active age bracket (including those who opted not to participate in work activities)

§Effects on the economy:
  • §Most of the labor force are found in agricultural activities, animal husbandry and forestry, and some are engaged in wholesale, and retail occupations. Only a small portion are involved in the manufacturing sector. This suggests that most of the labor force are employed in low productivity jobs. §In terms of educational qualifications, the majority have either have taken or finished primary schooling. This is followed closely by those who have reached secondary. Those who have taken and graduated from tertiary levels constitute the minority of those who have had some years of schooling.
  • §Mind power is often more important than muscular power. Human capital is supposed to improve a person’s productivity or muscular power.
  • §Filipinos are the most schooled of the peoples in Asia. A significant amount of the people have reached tertiary education, thereby aiming to improve human capital. §Human resources are not only used for domestic production, but are also gainfully employed in the international market. Filipino workers are almost all over the world. It is estimated the remittances of these Overseas Filipino workers (OFWs) contributed to the stability of the Philippine economy. But at the same time, international migration contributes to the brain drain problem since these people are not contributing directly in the local economy.

What?! EP gone GAAAAY !!

WHATTA DAYYY!!

everything started wrong this day..

  • UNA: woke up with no water drippin down the shitty faucet. caca! so i have to use tabo..

  • PANGATLO: hindi ko pa nasusukat yung costume ko for the english parade so i rushed it after i took a bath, okay naman siya, pero naubos yung time ko and ilang minuto nalang, dadating na yung service ko! so, panic mode!
  • PANGAPAT: my eye was ridiculously swollen, it looked really weird and icky. plus, it looked like i have sore eyes.
  • PANLIMA: english period. i was late for i took my physics test pa, so i was hurrying. sloppily dressed, i walked along with the parade. NALALAGLAG YUNG DAMIT KO WHILE WALKING!! i was like walking half-naked aroung the HS building!! haha. so instead na lalaki si EPIMETHEUS, yung wrap-around kumot ko ay naging parang pang babae! the GODDES EPIMETHEUS. [eew] hahaha!! thankfully, naayos naman..nung PATAPOS NA YUNG SUBJECT. WOW.

haay. so much for not being prepared. hahah!
pero masaya naman all in all :D
kaya niyo yun? :))

Estrada Administration

Joseph Estrada assumed his position as president last June 30 1998. He promised that he will improve the lives of the Filipino people during his term as a president but after a couple of years, he was impeached because of certain scams that he was involved in.

To help improve the situation of the Philippines, Estrada thought of ideas that will be beneficial to us. One of these was the abolishment of the Pork Barrel. This was the money of the people set aside for the Congress at their own disposal. The Congress would be able to use this money for their little projects and it also promotes corruption. Also, the Agrarian Reform Agenda was formed. This agenda is based upon the three (3) important principles. Social Justice which gives fairness to the Filipino farmers who are not given the right to own the land they till, the political democratization that “involves increasing state accountability to its rural citizenry” and lastly, extending the accessibility of basic needs to the poor especially the ones in provinces. It consists of several branches and these are the following:

Completion of Land acquisition and Distribution: Distribution of the 3.466 M hectares of land by end of June 2002. They also aim to double the amount of land being distributed. From 200,000 hectares of the previous administration, they aim to distribute 400,000 hectares of land per year.

Intensification of Agrarian Reform Beneficiary Development: The administration of Estrada hopes to find a balance in the allocation of funds because the two previous administrations weren’t able to do so.

Promotion of Democratic Agrarian Reform: Allows the widespread participation of the masses in the programs of the government regarding the Agrarian reforms and strengthening the NGOs and the farmers.

Estrada also initiated the use of rolling stores. He called these the “Erap Para Sa Mahirap” rolling stores. These rolling stores sold basic needs that will be affordable for the poor.

ECONOMIC PROBLEMS

Main problem of the Estrada Administration is Poverty

  1. The stock market is a tragedy

- Peso was weak, meaning the Peso-Dollar exchange was low ($1/P45)

- Control of stock trading in Manila by old line business families

  1. Terrorism

- Bombings in Manila (malls, bus) and hostages crisis

- Rebellion of Muslims (MILF)

  1. Landlords

- avoiding land reforms (government is in charge of the possession and use of land)

- converting farmlands to industrial or residential properties

- promotes deforestation and deteriorating agricultural sectors

  1. Population

- increase by 4%

- lesser jobs because human resources will increase = unemployment

- wages are lower

  1. Garbage

- no land for garbage disposal

- “NIMBY” Not in my back yard

- cause of sickness and disease

Reaction of the community/government

  1. Jokes about Erap

- poor english

- supported by poor people because of his films

- his education

  1. EDSA II

- people rebelled against his administration

  1. Fake EDSA III

- people who supported Erap
