Peroxisomes - Eukaryotic Organelles

Peroxisomes - Eukaryotic Organelles Peroxisomes are small organelles found in eukaryotic plant and animal cells. Hundreds of these round organelles can be found within a cell. Also known as microbodies, peroxisomes are bound by a single membrane and contain enzymes that produce hydrogen peroxide as a by-product. The enzymes decompose organic molecules through oxidation reactions, producing hydrogen peroxide in the process. Hydrogen peroxide is toxic to the cell, but peroxisomes also contain an enzyme that is capable of converting hydrogen peroxide to water. Peroxisomes are involved in at least 50 different biochemical reactions in the body. Types of organic polymers that are broken down by peroxisomes include amino acids, uric acid, and fatty acids. Peroxisomes in liver cells help to detoxify alcohol and other harmful substances through oxidation. Key Takeaways: Peroxisomes Peroxisomes, also known as microbodies, are organelles that are found in both eukaryotic animal and plant cells.A number of organic polymers are broken down by peroxisomes including amino acids, uric acid, and fatty acids. At least 50 different biochemical reactions in the body involve peroxisomes.Structurally, peroxisomes are surrounded by one membrane that encloses digestive enzymes. Hydrogen peroxide is produced as a by-product of peroxisome enzyme activity which decomposes organic molecules.Functionally, peroxisomes are involved in both the destruction of organic molecules and the synthesis of important molecules in the cell.Similar to mitochondria and chloroplast reproduction, peroxisomes have the ability to assemble themselves and reproduce by dividing in a process known as peroxisomal biogenesis. Peroxisomes Function In addition to being involved in the oxidation and decomposition of organic molecules, peroxisomes are also involved in synthesizing important molecules. In animal cells, peroxisomes synthesize cholesterol and bile acids (produced in the liver). Certain enzymes in peroxisomes are necessary for the synthesis of a specific type of phospholipid that is necessary for the building of heart and brain white matter tissue. Peroxisome dysfunction can lead to the development of disorders that affect the central nervous system as perioxsomes are involved in producing the lipid covering (myelin sheath) of nerve fibers. The majority of peroxisome disorders are the result of gene mutations that are inherited as autosomal recessive disorders. This means that individuals with the disorder inherit two copies of the abnormal gene, one from each parent. In plant cells, peroxisomes convert fatty acids to carbohydrates for metabolism in germinating seeds. They are also involved in photorespiration, which occurs when carbon dioxide levels become too low in plant leaves. Photorespiration conserves carbon dioxide by limiting the amount of CO2 available to be used in photosynthesis. Peroxisome Production Peroxisomes reproduce similarly to mitochondria and chloroplasts in that they have the ability to assemble themselves and reproduce by dividing. This process is called peroxisomal biogenesis and involves the building of the peroxisomal membrane, intake of proteins and phospholipids for organelle growth, and new peroxisome formation by division. Unlike mitochondria and chloroplasts, peroxisomes have no DNA and must take in proteins produced by free ribosomes in the cytoplasm. The uptake of proteins and phospholipids increases growth and new peroxisomes are formed as the enlarged peroxisomes divide. Eukaryotic Cell Structures In addition to peroxisomes, the following organelles and cell structures can also be found in eukaryotic cells: Cell Membrane: The cell membrane protects the integrity of the interior of the cell. It is a semi-permeable membrane that surrounds the cell.Centrioles: When cells divide, centrioles help to organize the assembly of microtubules.Cilia and Flagella: Both cilia and flagella aid in cellular locomotion and can also help move substances around cells.Chloroplasts: Chloroplasts are the sites of photosynthesis in a plant cell. They contain chlorophyll, a green substance that can absorb light energy.Chromosomes: Chromosomes are located in the cells nucleus and carry heredity information in the form of DNA.Cytoskeleton: The cytoskeleton is a network of fibers that support the cell. It can be thought of as the cells infrastructure.Nucleus: The cells nucleus controls cell growth and reproduction. It is surrounded by the nuclear envelope, a double-membrane.Ribosomes: Ribosomes are involved in protein synthesis. Most often, individual ribosomes have both a small and large subunit.Mitochondria: Mit ochondria provide energy for the cell. They are considered the cells power house. Endoplasmic Reticulum: The endoplasmic reticulum synthesizes carbohydrates and lipids. It also produces proteins and lipids for a number of cell components.Golgi Apparatus: The golgi apparatus manufactures, stores, and ships certain cellular products. It can be thought of as the shipping and manufacturing center of the cell.Lysosomes: Lysosomes digest cellular macromolecules. They contain a number of hydrolytic enzymes that help to break down cellular components.

Law of Definite Proportions Definition

Law of Definite Proportions Definition The law of definite proportions, together with the law of multiple proportions, forms the basis for the  study of stoichiometry  in chemistry. The law of definite proportions is also known as Prousts law or the law of constant composition. Law of Definite Proportions Definition The law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. The mass ratio of elements is fixed no matter where the elements came from, how the compound is prepared or any other factor. Essentially, the law is based on the fact that an atom of a particular element is the same as any other atom of that element. So, an atom of oxygen is the same, whether it comes from silica or oxygen in air. The Law of Constant Composition is an equivalent law, which states each sample of a compound has the same composition of elements by mass. Law of Definition Proportions Example The law of definite proportions says water will always contain 1/9 hydrogen and 8/9 oxygen by mass. The sodium and chlorine in table salt combine according to the rule in NaCl. The atomic weight of sodium is about 23 and that of chlorine is about 35, so from the law one may conclude dissociating 58 grams of NaCl would produce about 23 g of sodium and 35 g of chlorine. History of the Law of Definite Proportions Although the law of definite proportions may seem obvious to a modern chemist, the manner in which elements combine was not obvious in the early days of chemistry through the end of the 18th century. French chemist Joseph Proust (1754–1826) is credited with the discovery, but English chemist and theologian Joseph Priestly (1783–1804) and French chemist Antoine Lavoisier (1771–1794) were the first to publish the law as a scientific proposal in 1794, based on the study of combustion. They noted metals always combine with two proportions of oxygen. As we know today, oxygen in the air is a gas consisting of two atoms, O2. The law was hotly disputed when it was proposed. French chemist Claude Louis Berthollet (1748–1822) was an opponent, arguing elements could combine in any proportion to form compounds. It wasnt until English chemist John Dalton (1766–1844)s atomic theory explained the nature of atoms that the law of definite proportions became accepted. Exceptions to the Law of Definite Proportions Although the law of definite proportions is useful in chemistry, there are exceptions to the rule. Some compounds are non-stoichiometric in nature, meaning their elemental composition varies from one sample to another. For example, wustite is a type of iron oxide with an elemental composition varying between 0.83 and 0.95 iron atoms for each oxygen atom (23%–25% oxygen by mass). The ideal formula for iron oxide is FeO, but the crystal structure is such that there are variations. The formula for wustite is written Fe0.95O. Also, the isotopic composition of an element sample varies according to its source. This means the mass of a pure stoichiometric compound will be slightly different depending on its origin. Polymers also vary in element composition by mass, although they are not considered true chemical compounds in the strictest chemical sense.

Project Baton failed because there was a poor coordination between the US and Indian teams. The two teams focused their attention on two different parts of the new products. However, the level of communication between them was poor. The situation was worsened by time difference, variance in styles of communication, and different working styles, an aspect that increased distrust between the teams (Leon & Yong, 2012). The production unit caused the project to fail. For instance, the cost-cutting measures were very hard to implement. In addition, although the team that was assigned to develop the product had adequate experience in EKG production, it lacked the same knowledge in stress test systems (Leon & Yong, 2012). Management issues made the product to fail. For instance, the abrupt departure of the top manager bought chaos, an aspect that led to delays. Furthermore, the initial goals that were set by the company were too ambitious for the team to achieve. Furthermore, lack of guidance from top-level manager made the overall project to fail (Leon & Yong, 2012). Bella India should go on and develop the product for the local market because India has manufacturing advantages when compared to other countries. Therefore, it has a well trained and highly motivated workforce that can serve the Indian market. India has a high population that offers the company with an opportunity to expand its market share. Furthermore, the country is known globally for its health tourism (Leon & Yong, 2012). Therefore, more people are likely to come to India to seek health related services. This will increase the demand for the

Mood disorders Essay Example | Topics and Well Written Essays - 250 words

Mood disorders - Essay Example In addition there was also a complete loss of interest to do work unlike the normal days. Hobbies that were exiting earlier did not kindle any interest when under depression. Concentrating and decision making became extremely difficult. There was also a decrease in communication with people in the family as well as among friends. The normal routine processes such as sleeping and eating were also affected as there was no sound sleep and loss of appetite was also present. These also contributed to general body and mind weakness. All these led to suicidal tendencies as there was a constant fear in the mind and also a very pessimistic approach to life. Thus given my experiences, I would also expect similar symptoms in a client reportedly suffering from depression and hypomania. He/she should exhibit lack of interest in routine work to begin with as this would be the first noticeable symptom in these individuals as things that were exiting to perform earlier on would not mean anything during times of depression. These could be noticed and reported by the family. Other signs that could be overlooked by family members such as difficulty in remembering and concentrating, weight loss due to appetite loss and other physical changes due to erratic sleeping patterns would also have to be studied. In some cases the person might exhibit irritability and fear. They might break down suddenly without any reason or could burst out in anger. They might speak to themselves assuming they are addressing some other person. They could show decreased interest in sexual activities and other enjoyments. They would not care for their physical appearance and changes in their personal hygiene could also be present. A feeling of low-self esteem and unworthiness generally induces suicidal thoughts and the person might have attempted to suicide in one or more instances or might constantly talk about their

Teacher preparation is critical to providing successful quality math education Essay Example for Free

Teacher preparation is critical to providing successful quality math education Essay It is possible to make every student a successful student. Here success could mean different things to different students and their teachers. When the full potential of a student is realized in the chosen avocation, one can infer that success is achieved. Teaching and learning happen the best when there is perceived interest in both the teacher and the learner. Nurturing education through better teaching and learning methods can enhance the ability of a teacher for providing quality mathematics education1 (Chism,1998). Because of the inherent anxiety in math education, additional preparation in terms of understanding the psychology of the students is a critical success factor. Many times we find impediments to teaching and learning either because there is no evident interest in the teacher or the learner or both; or there is no proper supporting mechanism/ system to augment the teaching and learning. In the following paragraphs, an outline of various teaching / instructional methodologies for the teachers and learning strategies for the students are outlined for best possible outcomes for both sides of the equation. These are meant for any teaching including mathematics. Based on my own personal experiences of teaching and learning and professional research, I outlined a few of the many methodologies.   Mention is also made of the importance of overall learning environment. Teaching / Instructional Methodologies2 (New Horizons For Learning,2002) a. Action Research Action Research is a very powerful strategy for instructional improvement and provides teachers the necessary skills for solving problems specific to their classrooms and their schools. By using a five step process – question, data collection, data analysis, findings and action plan – teachers can improve their own teaching skills while improving their classroom/school outcomes3 (Reed, 2000) b. Differentiated Instruction Differentiated Instruction takes into account the various ways in which students learn as against Direct Instruction which focuses mainly on memorizing facts and skills. Differentiated Instruction on the other hand focuses on concepts, understanding, readiness and interest. c. Environment for Learning: The definition or perception of Learning Environment from a curriculum and instruction based learning is changing to an environment for successful learning which is based on a variety of emotional, intellectual, visual and spatial stimuli. Schools located in such environs as zoos, museums, culture are redefining the way learning takes place and learning environment is created. d. Accelerated Learning Accelerated learning is based on the original work of ‘Suggestology’4 (Dr. Lozanov, 1978) which included relaxation, visual arts and music for teaching foreign language students. Accelerated learning takes into account various beliefs/theories such as Learning is dual-planned; there is no single stimulus etc. The Core Elements for Accelerated Learning include Physical Environment, Music, Teacher, Positive Atmosphere and a teaching Frame. Teaching Frame in turn includes three phases – Preparation, Active and Passive. e. Teaching for Understanding: This approach seeks to get answers to the three key questions: 1. What does it mean to understand? 2. How do we teach for understanding? 3. How do we assess understanding? Using the concept of ‘throughlines’ a teacher can engage the students continuously and throughout the year on the goals set out for understanding the concepts based on a set of predefined questions. Classroom based Learning Continuum Tool The Northwest Evaluation Association launched a tool   DesCartes: A Continuum of Learning. This tool is designed for teachers and principals to simplify the task of translating assessment data into specific skills and concepts5 (Business Wire, 2004). The tool is used to map mathematics, reading, and language usage skills along a continuum of learning, and connects each skill with test score ranges and state standards for all the states Teachers can use DesCartes information for: †¢ Identification of specific skills and concepts students need †¢ Selection of materials based on the diversity of skill levels within a class, and find appropriate materials for students at the extreme ends of the learning spectrum. †¢ Creation of flexible learning groups based on students performance and †¢ Collaboration with staff to successfully meet the needs of all learners6 (Grasha, 1996). Conclusion Teaching and Learning have become very critical in not only realizing the full potential of the learners but in doing so have become necessary tools to build a productive workforce. Teaching styles6, improvements in technology and expectations of parents, society have contributed to the growth of new methods of teaching, learning and creating new Learning Environments. Hence it is important that we assess the teachers for their ability and aptitude and also assess the learner’s ability and aptitude. A match making of these two would most definitely produce successful teaching and learning outcomes. Many of the methods discussed above would definitely make it is possible for every student to become a successful student and every teacher a successful teacher.

History of Jamaica Essay -- Essays Papers

History of Jamaica Columbus discovered Jamaica on May 5, 1494, one year after he heard of the existence of the island. However, the true history of Jamaica begins with the African-Jamaican people who came to the island twenty years after the English took control from the Spaniards. The history of Jamaica can be broken up into different time periods, which were defined by watershed moments or events. Jamaican history begins with the establishment of the native islanders called the Tainos who inhabited the island for hundreds of years before the discoveries of Columbus. (JNHT 1) The Tainos are a subgroup of the Arawak people who were first native to South America. These indigenous groups traveled by canoe to the Caribbean islands hundreds of years prior to the arrival of Europeans. The Tainos developed the first social, political, and economical systems on the island of Jamaica. Their social system followed the beliefs of their many gods who could be found in almost any material or animal. The political system constructed was similar to the hierarchy of many European countries with a Chief and nobles. The nobles acted as advisors to the Chief and every citizen in the tribe had a role in the community. Also regions were divided by geographical location and ruled by chiefdoms. The Tainos economic system was basic and simple compared with the standards of today. It was based on fishing and hunting from the surrounding environment. Large mounds were used to slow the process of erosion and to improve drainage to better the living conditions in the tropic al climate. The fourth voyage of Columbus in 1494 established a Spanish influence in Jamaica. The original people of Jamaica, the Tainos, were severely devastated by the Spanish invasion. The Taino population declined every year after the arrival of Columbus due to the spread of new diseases which they had little immunity to. Having little access to the already poor treatments and medicines available at the time furthered the decrease in Taino population. The Taino population decreased by more than half of their original population by 1598 because of Spanish presence. (Carley) New Seville became the first settlement built by the Spanish in 1510. Nueva Sevilla was governed by Columbus' son Di... ...nging of the capital and political system was a shift in island productions from sugar to bananas. (Sherlock) The Great Depression, which affected everyone in the world during the 1930’s, was another event that brought about positive changes in Jamaica. Jamaica’s depression came towards the end of the United States depression. Coinciding with the depression was the leaf spot disease found on bananas causing exports to decrease as well as job opportunities. The decline in social conditions resulted in labor riots that ended with the deaths of a few workers, but turned Jamaica into a self-Independent nation. The economic revolution can be characterized as a â€Å"Cultural Revolution† because of the Jamaicans binding together in times of adversity and pushing for a more democratic system (Carley 195). The leader of the labor riots, Alexander Bustamante, became the first Prime Minister of Jamaica. In 1944, voting rights were given to all Jamaicans 21 and older; also in 1944, the Jamaican Labor party gained control of the government. After years of struggles and repr ession from European dominance, Jamaica finally gained full independence from England on August 5, 1962. (JNHT 4)

Forward the Foundation Chapter 29

32 â€Å"Professor Seldon come in,† said Chief Librarian Tryma Acarnio in an icy tone of voice. Hari Seldon accompanied by Wanda and Palver, entered the Chief Librarian's imposing office. â€Å"Thank you, Chief Librarian,† said Seldon as he settled into a chair and faced Acarnio across the vast desk. â€Å"May I introduce my granddaughter Wanda and my friend Stettin Palver. Wanda is a most valuable member of the Psychohistory Project, her specialty being in the field of mathematics. And Stettin, well, Stettin is turning into a first-rate general psychohistorian-when he's not performing his duties as my bodyguard, that is.† Seldon chuckled amiably. â€Å"Yes, well, that's all well and good, Professor,† said Acarnio, baffled by Seldon's good humor. He had expected the professor to come in groveling, begging for another chance at special Library privileges. â€Å"But I don't understand what it is you wanted to see me about. I assume you realize that our position is firm: We cannot allow a Library association with someone so extremely unpopular with the general population. We are, after all, a public library and we must keep the public's sentiments in mind.† Acarnio settled back-perhaps now the groveling would begin. â€Å"I realize that I have not been able to sway you. However, I thought that if you heard from a couple of the Project's younger members-the psychohistorians of tomorrow, as it were-that perhaps you'd get a better feel about what a vital role the Project-and the Encyclopedia, in particular-will play in our future. Please hear Wanda and Stettin out.† Acarnio cast a cold eye toward the two young people flanking Seldon. â€Å"Very well, then,† he said, pointedly eyeing the timestrip on the wall. â€Å"Five minutes and no more. I have a Library to run.† â€Å"Chief Librarian,† began Wanda, â€Å"as my grandfather has undoubtedly explained to you, psychohistory is a most valuable tool to be used for the preservation of our culture. Yes, preservation, † she repeated, upon seeing Acarnio's eyes widen at the word. â€Å"Undue emphasis has been placed on the destruction of the Empire. By doing so, the true value of psychohistory has been overlooked. For, with psychohistory, as we are able to predict the inevitable decline of our civilization, so are we able to take steps toward its preservation. That is what the Encyclopedia Galactica is all about. And that is why we need your help, and the help of your great Library.† Acarnio could not resist smiling. The young lady had an undeniable charm. She was so earnest, so well spoken. He gazed at her sitting in front of him, her blond hair pulled back in a rather severe scholarly style, one which could not hide her attractive features but, rather, showed them off. What she was saying was starting to make sense. Maybe Wanda Seldon was right-maybe he had been looking at this problem from the wrong angle. If it were actually a matter of preservation, rather than destruction†¦ â€Å"Chief Librarian,† began Stettin Palver, â€Å"this great Library has stood for millennia. It, perhaps even more than the Imperial Palace, represents the vast power of the Empire. For, the Palace houses only the Empire's leader, while the Library is home to the sum total of Imperial knowledge, culture, and history. Its value is incalculable. â€Å"Does it not make sense to prepare a tribute to this great repository? The Encyclopedia Galactica will be just that-a giant summary of all the knowledge contained within these very walls. Think of it!† All of a sudden it seemed so very clear to Acarnio. How could he have let the Board (especially that sourpuss Gennaro Mummery) convince him to rescind Seldon's privileges? Las Zenow, a person whose judgment he greatly esteemed, had been a wholehearted supporter of Seldon's Encyclopedia. He glanced again at the three in front of him, waiting for his decision. The Board would be hard-pressed to find anything to complain about with the Project members-if the young people now in his office were a representative sample of the kind of persons involved with Seldon. Acarnio rose and walked across his office, his brow furrowed, as if framing his thoughts. He picked up a milky crystal sphere from a table and hefted it in his palm. â€Å"Trantor,† Acarnio began thoughtfully, â€Å"seat of the Empire, center of all the Galaxy. Quite amazing, when you think of it. We have, perhaps, been too quick to judge Professor Seldon. Now that your Project, this Encyclopedia Galactica, has been presented to me in such a light†-he gave a brief nod to Wanda and Palver-â€Å"I realize how important it would be to allow you to continue your work here. And, of course, to grant access to a number of your colleagues.† Seldon smiled gratefully and squeezed Wanda's hand. â€Å"It is not only for the greater glory of the Empire that I am recommending this,† continued Acarnio, apparently warming to the idea (and the sound of his own voice). â€Å"You are famous, Professor Seldon. Whether people think of you as a crackpot or a genius, everyone seems to have an opinion. If an academic of your stature is allied with the Galactic Library, it can only increase our prestige as a bastion of intellectual pursuit of the highest order. Why, the luster of your presence can be used to raise much-needed funds to update our collections, increase our staff, keep our doors open to the public longer†¦ â€Å"And the prospect of the Encyclopedia Galactica itself-what a monumental project! Imagine the reaction when the public learns that the Galactic Library is involved with such an undertaking designed to highlight the splendor of our civilization-our glorious history, our brilliant achievements, our magnificent cultures. And to think that I, Chief Librarian Tryma Acarnio, is responsible for making sure that this great Project gets its start-† Acarnio gazed intently into the crystal sphere, lost in reverie. â€Å"Yes, Professor Seldon,† Acarnio pulled himself back to the here and now. â€Å"You and your colleagues will be granted full insiders' privileges-and a suite of offices in which to work.† He placed the crystal sphere back on its table and, with a swish of robes, moved back to his desk. â€Å"It might take a little doing, of course, to persuade the Board-but I am confident that I can handle them. Just leave it to me.† Seldon, Wanda, and Palver looked at each other in triumph, with small smiles playing at the corner of their mouths. Tryma Acarnio gestured that they could go and so they did, leaving the Chief Librarian settled in his chair, dreaming of the glory and honor that would come to the Library under his aegis. â€Å"Amazing,† said Seldon when the three were safely ensconced in their ground-car. â€Å"If you could have seen him at our last meeting. He said I was ‘threatening the essential fabric of our Empire' or some such rot. And today, after just a few minutes with you two-â€Å" â€Å"It wasn't too hard, Grandpa,† Wanda said as she pressed a contact, moving the ground-car out into traffic. She sat back as the auto-propel took over; Wanda had punched their destination coordinates into the control panel. â€Å"He is a man with a strong sense of self-importance. All we had to do was play up the positive aspects of the Encyclopedia and his ego took over from there.† â€Å"He was a goner the minute Wanda and I walked in,† Palver said from the back. â€Å"With both of us pushing him, it was a piece of cake.† Palver reached forward and squeezed Wanda's shoulder affectionately. She smiled, reached up, and patted his hand. â€Å"I must alert the Encyclopedists as soon as possible,† Seldon said. â€Å"Although there are only thirty-two left, they are good and dedicated workers. I'll get them installed at the Library and then I'll tackle the next hurdle-credits. Perhaps this alliance with the Library is what I need to convince people to give us funding. Let's see-I'll call upon Terep Bindris again and I'll take you two with me. He was kindly disposed toward me, at least at first. But how will he be able to resist us now?† The ground-car eventually came to a halt outside the Psychohistory Building at Streeling. The side panels slid open, but Seldon did not immediately move to disembark. He turned to face Wanda. â€Å"Wanda, you know what you and Stettin were able to accomplish with Acarnio; I'm sure you both can push some credits out of a few financial benefactors as well. â€Å"I know how you hate to leave your beloved Prime Radiant, but these visits will give you two a chance to practice, to hone your skills, to get an idea of just what you can do.† â€Å"All right, Grandpa, although I'm sure that, now that you have the Library's imprimatur, you will find that resistance to your requests has lessened.† â€Å"There's another reason I think it's important for the two of you to get out and around together. Stettin, I believe you said that on certain occasions you've ‘felt' another mind like yours but haven't been able to identify it.† â€Å"Yes,† answered Palver, â€Å"I've had flashes, but each time I was in a crowd. And, in my twenty-four years, I can remember feeling such a flash just four or five times.† â€Å"But, Stettin,† said Seldon, his voice low with intensity, â€Å"each flash was, potentially, the mind of another person like you and Wanda-another mentalic. Wanda's never felt these flashes because, frankly, she's been sheltered all her life. The few times she's been out in a crowd there must not have been any other mentalics around. â€Å"That's one reason-perhaps the most important reason-for you two to get out-with me or without me. We must find other mentalics. The two of you alone are strong enough to push a single person. A large group of you, all pushing together, will have the power to move an Empire!† With that. Hari Seldon swung his legs around and hoisted himself out of the ground-car. As Wanda and Palver watched him limp up the pathway to the Psychohistory Building, they were only dimly aware of the enormous responsibility Seldon had just placed on their young shoulders. 33 It was midafternoon and the Trantorian sun glinted on the metal skin covering the great planet. Hari Seldon stood at the edge of the Streeling University observation deck, attempting to shield his eyes from the harsh glare with his hand. It had been years since he'd been out from under the dome, save for his few visits to the Palace, and somehow those didn't count; one was still very much enclosed on the Imperial grounds. Seldon no longer traveled around only if accompanied. In the first place, Palver spent the majority of his time with Wanda, either working on the Prime Radiant, absorbed in mentalic research, or searching for others like them. But if he had wanted, Seldon could have found another young man-a University student or a Project member-to act as his bodyguard. However, Seldon knew that a bodyguard was no longer necessary. Since the much publicized hearing and the reestablishment of ties with the Galactic Library, the Commission for Public Safety had taken a keen interest in Seldon. Seldon knew that he was being followed; he had caught sight of his â€Å"shadow† on a number of occasions in the past few months. He also had no doubt that his home and office had been infiltrated by listening devices, but he himself activated a static shield whenever he engaged in sensitive communications. Seldon was not sure what the Commission thought of him-perhaps they were not yet sure themselves. Regardless of whether they believed him to be a prophet or a crackpot, they made it their business to know where he was at all times-and that meant that, until the Commission deemed otherwise, at all times Seldon was safe. A light breeze billowed the deep blue cloak Seldon had draped over his unisuit and ruffed the few wispy white hairs remaining on his head. He glanced down over the railing, taking in the seamless steel blanket below. Beneath that blanket, Seldon knew, rumbled the machinery of a vastly complicated world. If the dome were transparent, one would see ground-cars racing, gravicabs swooshing through an intricate network of interconnecting tunnels, space hyperships being loaded and unloaded with grain and chemicals and jewels bound for and from practically every world of the Empire. Below the gleaming metal cover, the lives of forty billion people were being conducted, with all the attendant pain, joy, and drama of human life. It was an image he loved dearly-this panorama of human achievement-and it pierced his heart to know that, in just a few centuries, all that now lay before him would be in ruins. The great dome would be ripped and scarred, torn away to reveal the desolate wasteland of what was once the seat of a thriving civilization. He shook his head in sadness, for he knew there was nothing he could do to prevent that tragedy. But, as Seldon foresaw the ruined dome, he also knew that from the ground laid bare by the last battles of the Empire living shoots would spring and somehow Trantor would reemerge as a vital member of the new Empire. The Plan saw to that. Seldon lowered himself onto one of the benches ringing the deck's perimeter. His leg was throbbing painfully; the exertion of the trip had been a bit much. But it had been worth it to gaze once again at Trantor, to feel the open air around him and see the vast sky above. Seldon thought wistfully of Wanda. He rarely saw his granddaughter at all anymore and invariably Stettin Palver was present when he did. In the three months since Wanda and Palver had met, they seemed to be inseparable. Wanda assured Seldon that the constant involvement was necessary for the Project, but Seldon suspected it went deeper than mere devotion to one's job. He remembered the telltale signs from his early days with Dors. It was there in the way the two young people looked at each other, with an intensity born not only of intellectual stimulation but emotional motivation as well. Further, by their very natures, Wanda and Palver seemed to be more comfortable with each other than with other people. In fact, Seldon had discovered that when no one else was around, Wanda and Palver didn't even talk to each other; their mentalic abilities were sufficiently advanced that they had no need of words to communicate. The other Project members were not aware of Wanda's and Palver's unique talents. Seldon had felt it best to keep the mentalics' work quiet, at least until their role in the Plan was firmly defined. Actually the Plan itself was firmly defined-but solely in Seldon's mind. As a few more pieces fell into place, he would reveal his Plan to Wanda and Palver and someday, of necessity, to one or two others. Seldon stood slowly, stiffly. He was due back at Streeling in an hour to meet Wanda and Palver. They had left word for him that they were bringing a great surprise. Another piece for the puzzle, Seldon hoped. He looked out one last time over Trantor and, before turning to make his way back to the gravitic repulsion elevator, smiled and softly said, â€Å"Foundation.† 34 Hari Seldon entered his office to find that Wanda and Palver had already arrived and were seated around the conference table at the far end of the room. As was usual with those two, the room was completely silent. Then Seldon stopped short, noticing that a new fellow was sitting with them. How strange-out of politeness, Wanda and Palver usually reverted to standard speech when in the company of other people, yet none of the three was speaking. Seldon studied the stranger-an odd-looking man, about thirty-five years old, with the myopic look of one caught up for too long in his studies. If it weren't for a certain determined set to the stranger's jaw, Seldon thought he might be dismissed as ineffectual, but that would obviously be a mistake. There was both strength and kindness in the man's face. A trustworthy face, Seldon decided. â€Å"Grandfather,† Wanda said, rising gracefully from her chair. Seldon's heart ached as he looked at his granddaughter. She'd changed so much in the past few months, since the loss of her family. Whereas before she had always called him Grandpa, now it was the more formal Grandfather. In the past it seemed she could barely refrain from grins and giggles; lately her serene gaze was lightened only occasionally by a beatific smile. But-now as always-she was beautiful and that beauty was surpassed only by her stunning intellect. â€Å"Wanda, Palver,† Seldon said, kissing the former on the cheek and slapping the latter on the shoulder. â€Å"Hello,† Seldon said, turning to the stranger, who had also stood. â€Å"I am Hari Seldon.† â€Å"I am most honored to meet you, Professor,† the man replied. â€Å"I am Bor Alurin.† Alurin offered a hand to Seldon in the archaic and, hence, most formal mode of greeting. â€Å"Bor is a psychologist, Hari,† said Palver, â€Å"and a great fan of your work.† â€Å"More important, Grandfather,† said Wanda, â€Å"Bor is one of us.† â€Å"One of you?† Seldon looked searchingly from one to the other. â€Å"Do you mean†¦?† Seldon's eyes sparkled. â€Å"Yes, Grandfather. Yesterday Stettin and I were walking through Ery Sector, getting out and around, as you'd suggested, probing for others. All of a sudden-wham!-there it was.† â€Å"We recognized the thought patterns immediately and began to look around, trying to establish a link,† Palver said, taking up the story. â€Å"We were in a commercial area, near the spaceport, so the walkways were clogged with shoppers and tourists and Outworld traders. It seemed hopeless, but then Wanda simply stopped and signaled Come here and out of the crowd Bor appeared. He just walked up to us and signaled Yes?† â€Å"Amazing,† Seldon said, beaming at his granddaughter. â€Å"And Dr.-it is Doctor, isn't it?-Alurin, what do you make of all this?† â€Å"Well,† began the psychologist thoughtfully, â€Å"I am pleased. I've always felt different somehow and now I know why. And if I can be of any help to you, why-† The psychologist looked down at his feet, as if all of a sudden he realized he was being presumptuous. â€Å"What I mean is, Wanda and Stettin said I may be able to contribute in some way to your Psychohistory Project. Professor, nothing would please me more.† â€Å"Yes yes. That's quite true, Dr. Alurin. In fact, I think you may make a great contribution to the Project-if you'll join me. Of course, you'll have to give up whatever it is you do now, whether it is teaching or private practice. Can you manage that?† â€Å"Why, yes, Professor, of course. I may need a little help convincing my wife-† At this he chuckled slightly, glancing shyly at each of his three companions in turn. â€Å"But I seem to have a way with that.† â€Å"So it's set, then,† said Seldon briskly. â€Å"You will join the Psychohistory Project. I promise you, Dr. Alurin, this is a decision you will not regret.† â€Å"Wanda, Stettin,† Seldon said later, after Bor Alurin had left. â€Å"This is a most welcome breakthrough. How quickly do you think you can find more mentalics?† â€Å"Grandfather, it took us over a month to locate Bor-we cannot predict with what frequency others will be found. â€Å"To tell you the truth, all this ‘out and around' takes us away from our work on the Prime Radiant and it is distracting as well. Now that I have Stettin to ‘talk' to, verbal communication is somewhat too harsh, too loud. â€Å" Seldon's smile faded. He had been afraid of this. As Wanda and Palver had been honing their mentalic skills, so their tolerance for â€Å"ordinary† life had diminished. It only made sense; their mentalic manipulations set them apart. â€Å"Wanda, Stettin, I think it may be time for me to tell you more about the idea Yugo Amaryl had years ago and about the Plan I've devised as a result of that idea. I haven't been ready to elaborate upon it until now, because until this moment, all the pieces have not been in place. â€Å"As you know, Yugo felt we must establish two Foundations-each as a fail-safe measure for the other. It was a brilliant idea, one which I wish Yugo could have lived long enough to see realized.† Here Seldon paused, heaving a regretful sigh. â€Å"But I digress. Six years ago, when I was certain that Wanda had mentalic, or mind-touching, capabilities, it came to me that not only should there be two Foundations but that they should be distinct in nature, as well. One would be made up of physical scientists-the Encyclopedists will be their pioneer group on Terminus. The second would be made up of true psychohistorians; mentalists-you. That is why I've been so eager for you to find others like you. â€Å"Finally, though, is this: The Second Foundation must be secret. Its strength will lie in its seclusion, in its telepathic omnipresence and omnipotence. â€Å"You see, a few years ago, when it became apparent that I would require the services of a bodyguard, I realized that the Second Foundation must be the strong, silent, secret bodyguard of the primary Foundation. â€Å"Psychohistory is not infallible-its predictions are, however, highly probable. The Foundation, especially in its infancy, will have many enemies, as do I today. â€Å"Wanda, you and Palver are the pioneers of the Second Foundation, the guardians of the Terminus Foundation.† â€Å"But how, Grandfather?† demanded Wanda. â€Å"We are just two-well, three, if you count Bor. To guard the entire Foundation, we would need-â€Å" â€Å"Hundreds? Thousands? Find however many it takes, Granddaughter. You can do it. And you know how. â€Å"Earlier, when relating the story of finding Dr. Alurin, Stettin said you simply stopped and communicated out to the mentalic presence you felt and he came to you. Don't you see? All along I've been urging you to go out and find others like you. But this is difficult, almost painful for you. I realize now that you and Stettin must seclude yourselves, in order to form the nucleus of the Second Foundation. From there you will cast your nets into the ocean of humanity.† â€Å"Grandfather, what are you saying?† Wanda asked in a whisper. She had left her seat and was kneeling next to Seldon's chair. â€Å"Do you want me to leave?† â€Å"No, Wanda,† Seldon replied, his voice choked with emotion. â€Å"I don't want you to leave, but it is the only way. You and Stettin must isolate yourselves from the crude physicality of Trantor. As your mentalic abilities grow stronger, you will attract others to you-the silent and secret Foundation will grow. â€Å"We will be in touch-occasionally, of course. And each of us has a Prime Radiant. You see, don't you, the truth-and the absolute necessity-of what I am saying, don't you?† â€Å"Yes, I do, Grandfather,† said Wanda. â€Å"More important, I feel the brilliance of it as well. Rest assured; we won't let you down.† â€Å"I know you won't, dear,† Seldon said wearily. How could he do this-how could he send his darling granddaughter away? She was his last link to his happiest days, to Dors, Yugo, and Raych. She was the only other Seldon in the Galaxy. â€Å"I shall miss you terribly, Wanda,† Seldon said as a tear worked its way down his finely creased cheek. â€Å"But, Grandfather,† Wanda said as she stood with Palver, preparing to leave. â€Å"Where shall we go? Where is the Second Foundation?† Seldon looked up and said, â€Å"The Prime Radiant has already told you, Wanda.† Wanda looked at Seldon blankly, searching her memory. Seldon reached out and clutched at his granddaughter's hand. â€Å"Touch my mind, Wanda. It is there.† Wanda's eyes widened as she reached into Seldon's mind. â€Å"I see,† Wanda whispered to Seldon. Section 33A2D17. Star's End. Part V Epilogue I am Hari Seldon. Former First Minister to Emperor Cleon I. Professor Emeritus of Psychohistory at Streeling University on Trantor. Director of the Psychohistory Research Project. Executive Editor of the Encyclopedia Galactica. Creator of the Foundation. It all sounds quite impressive, I know. I have done a great deal in my eighty-one years and I am tired. Looking back over my life, I wonder if I could have-should have-done certain things differently. For instance: Was I so concerned with the grand sweep of psychohistory that the people and events that intersected my life sometimes seemed inconsequential by comparison? Perhaps I neglected to make some small incidental adjustments here or there that would have in no way compromised the future of humanity but might have dramatically improved the life of an individual dear to me. Yugo, Raych†¦ I can't help but wonder†¦ Was there something I could have done to save my beloved Dors? Last month I finished recording the Crisis holograms. My assistant, Gaal Dornick, has taken them to Terminus to oversee their installation in the Seldon Vault. He will make sure that the Vault is sealed and that the proper instructions are left for the eventual openings of the Vault, during the Crises. I'll be dead by then, of course. What will they think, those future Foundationers, when they see me (or, more accurately, my hologram) during the First Crisis, almost fifty years from now? Will they comment on how old I look or how weak my voice is or how small I seem, bundled in this wheelchair? Will they understand-appreciate-the message I've left for them? Ah well, there's really no point in speculating. As the ancients would say: The die is cast. I heard from Gaal yesterday. All is going well on Terminus. Bor Alurin and the Project members are flourishing in â€Å"exile.† I shouldn't gloat, but I can't help but chuckle when I recall the self-satisfied look on the face of that pompous idiot Linge Chen when he banished the Project to Terminus two years ago. Although ultimately the exile was couched in terms of an Imperial Charter (â€Å"A state-supported scientific institution and part of the personal domain of His August Majesty, the Emperor†-the Chief Commissioner wanted us off Trantor and out of his hair, but he could not bear the thought of giving up complete control), it is still a source of secret delight to know that it was Las Zenow and I who chose Terminus as Foundation's home. My one regret where Linge Chen is concerned is that we were not able to save Agis. That Emperor was a good man and a noble leader, even if he was Imperial in name only. His mistake was to believe in his title and the Commission of Public Safety would not tolerate the burgeoning Imperial independence. I often wonder what they did to Agis-was he exiled to some remote Outer World or assassinated like Cleon? The boy-child who sits on the throne today is the perfect puppet Emperor. He obeys every word Linge Chen whispers in his ear and fancies himself a budding statesman. The Palace and trappings of Imperial life are but toys to him in some vast fantastical game. What will I do now? With Gaal finally gone to join the Terminus group, I am utterly alone. I hear from Wanda occasionally. The work at Star's End continues on course; in the past decade she and Stettin have added dozens of mentalics to their number. They increasingly grow in power. It was the Star's End contingent-my secret Foundation-who pushed Linge Chen into sending the Encyclopedists to Terminus. I miss Wanda. It has been many years since I've seen her, sat with her quietly, holding her hand. When Wanda left, even though I had asked her to go, I thought I would die of heartbreak. That was, perhaps, the most difficult decision I ever had to make and, although I never told her, I almost decided against it. But for the Foundation to succeed, it was necessary for Wanda and Stettin to go to Star's End. Psychohistory decreed it, so perhaps it wasn't really my decision, after all. I still come here every day, to my office in the Psychohistory Building. I remember when this structure was filled with people, day and night. Sometimes I feel as if it's filled with voices, those of my long-departed family, students, colleagues-but the offices are empty and silent. The hallways echo with the whirr of my wheelchair motor. I suppose I should vacate the building, return it to the University to allocate to another department. But somehow it's hard to let go of this place. There are so many memories†¦ All I have now is this, my Prime Radiant. This is the means by which psychohistory can be computed, through which every equation in my Plan may be analyzed, all here in this amazing, small black cube. As I sit here, this deceptively simple-looking tool in the palm of my hand, I wish I could show it to R. Daneel Olivaw†¦ But I am alone, and need only to close a contact for the office lights to dim. As I settle back in my wheelchair, the Prime Radiant activates, its equations spreading around me in three-dimensional splendor. To the untrained eye, this multicolored swirl would be merely a jumble of shapes and numbers, but for me-and Yugo, Wanda, Gaal-this is psychohistory, come to life. What I see before me, around me, is the future of humanity. Thirty thousand years of potential chaos, compressed into a single millennium†¦ That patch, glowing more strongly day by day, is the Terminus equation. And there-skewed beyond repair-are the Trantor figures. But I can see†¦ yes, softly beaming, a steady light of hope†¦ Star's End! This-this-was my life's work. My past-humanity's future. Foundation. So beautiful, so alive. And nothing can†¦ Dors! SELDON, HARI-†¦ found dead, slumped over his desk in his office at Streeling University in 12,069 G.E. (1 F.E.). Apparently Seldon had been working up to his last moments on psychohistorical equations; his activated Prime Radiant was discovered clutched in his hand†¦ According to Seldon's instructions, the instrument was shipped to his colleague Gaal Dornick who had recently emigrated to Terminus†¦ Seldon's body was jettisoned into space, also in accordance with instructions he'd left. The official memorial service on Trantor was simple, though well attended. It is worth noting that Seldon's old friend former First Minister Eto Demerzel attended the event. Demerzel had not been seen since his mysterious disappearance immediately following the Joranumite Conspiracy during the reign of Emperor Cleon I. Attempts by the Commission of Public Safety to locate Demerzel in the days following the Seldon memorial proved to be unsuccessful†¦ Wanda Seldon, Hari Seldon's granddaughter, did not attend the ceremony. It was rumored that she was grief-stricken and had refused all public appearances. To this day, her whereabouts from then on remain unknown†¦ It has been said that Hari Seldon left this life as he lived it, for he died with the future he created unfolding all around him†¦ Encyclopedia Galactica [1] All quotations from the Encyclopedia Galactica here reproduced are taken from the 116th Edition, published 1,020 F.E. by the Encyclopedia Galactica Publishing Co., Terminus, with permission of the publishers.

Noticeable signs of an unhealthy diet are dull, weak hair; poor gum and teeth health, and weight gain. An unwholesome diet can also cause chronic illnesses such as diabetes, high cholesterol, and heart disease. Being conscious of what you eat through out the day will provide you with the energy and nutrients required to survive and stay healthy. You should eat a variety of foods from every food group to get the essential vitamins and minerals for optimal health.The major food groups are grains, which includes breads and pasta; meat and legumes, such as fish, nuts, and beans; fruits and vegetables including green leafy vegetables and sweet potatoes; dairy products, such as milk and yogurt; and healthy fats and oils. The goal here is to focus not on dieting, but on a healthy approach to eating. If you keep up with your conscious healthy eating habits, as time goes on you will also start to see a change i n your weight. Even just losing as little as five percent of body weight can improve your blood pressure, cholesterol, and blood sugar levels.Eat what you love, and love what you eat. Learn how to get in touch with your hunger. No one eats perfectly all the time, but when you start to pay attention to the taste of food, you can be satisfied with out going overboard. You can eat everything you want still but do it in a moderation. You can choose to have one or the other. For example, if you want to have dessert then don't have a glass of wine. If you happen to be craving french fries from McDonalds go for it! Skip the hamburger and the McFlurry.You don't need to deprive yourself with the food that you love. DeLuca 2 Many people hear the word diet and may get discouraged and think they cant do it because they don't like healthy foods and it just doesn’t work for them. Really to have a good diet is to just balance out your calories so you can just indulge in one or the other, wh ile still keeping you sane with your cravings. Healthy eating is not a diet. It means making changes you can live with and enjoy for the rest of your life. Diets are temporary because you give up so much when you diet.After you stop dieting you may also over treat yourself to make up for what you have missed. Eating a healthy, balanced variety of foods is far more satisfying. Other than balance and moderation a change to healthier eating also helps you learn about variety. Be adventurous and try different foods. For example, don't reach for an apple every time you choose a fruit. Eating a variety of foods each day will help you get the nutrients you need. Another big problem that many folks seem to struggle with is to have a big full breakfast in the morning.Maybe your tired or busy, it can even be that you might just not have enough time for that. What many people may not know though is that eating fully in the morning will give you energy for the day and by bed time you will have it worked out. After taking pleasure in your tremendous breakfast, after a couple hours its only normal to start to feel hungry again so you will go and look for something to snack on. Snacking is not bad, its actually quite good! You can enjoy your favorite clean eats with out guilt all day.Just space them out. If you love high calories foods such as nuts, dairy, peanut butter, etc. you can eat it all! Spacing out meals keeps your metabolism high which means you will continuously burn calories, keep your blood sugar levels stable, and your stomach and mind satisfied. DeLuca 3 Having a busy week schedule may also be another reason as to why some people don’t get the healthy nutrients that they need, because you just don’t have enough time to eat. Well if your constantly on the go then you need to get your energy somehow.You can prepare healthy meals the night before hand and keep them in containers that you can take on the go with you the next day. You can also pack nu ts and fruit to bring to the office so you can snack, because remember its a good thing to do. After a long hard work week, or an exhausting week with school or your children its only normal to throw a few back! When going out for cocktails you should always keep in mind the calorie benefits with your alcoholic beverages. As you should know some beverages are better than others calorie wise.You can pick a red wine over a sugar infested margarita and you can also swap the dark liquored drinks for the light. Just a few small changes like this can go a long way. We all need a little discipline in our lives. So all in all remember that conscious healthy eating is not dieting. The small moderation changes, the variety, and the balance of healthy eating will give you a longer healthier life with out making huge drastic changes that puts a burden on your normal everyday life. If you start these small changes today, you are going to be happier with yourself and how you feel in the long run.

History of the American Labor Movement

History of the American Labor Movement The American labor force has changed profoundly during the nations evolution from an agrarian society into a modern industrial state. The United States remained a largely agricultural nation until late in the 19th century. Unskilled workers fared poorly in the early U.S. economy, receiving as little as half the pay of skilled craftsmen, artisans, and mechanics. About 40 percent of workers in cities were low-wage laborers and seamstresses in clothing factories, often living in dismal circumstances. With the rise of factories, children, women, and poor immigrants were commonly employed to run machines. Rise and Fall of Labor Unions The late 19th century and the 20th century brought substantial industrial growth. Many Americans left farms and small towns to work in factories, which were organized for mass production and characterized by steep hierarchy, a reliance on relatively unskilled labor, and low wages. In this environment, labor unions gradually developed clout. One such union was the Industrial Workers of the World, founded in 1905. Eventually, they won substantial improvements in working conditions. They also changed American politics; often aligned with the Democratic Party, unions represented a key constituency for much of the social legislation enacted from the time of President Franklin D. Roosevelts New Deal in the 1930s through the Kennedy and Johnson administrations of the 1960s. Organized labor continues to be an important political and economic force today, but its influence has waned markedly. Manufacturing has declined in relative importance, and the service sector has grown. More and more workers hold white-collar office jobs rather than unskilled, blue-collar factory jobs. Newer industries, meanwhile, have sought highly skilled workers who can adapt to continuous changes produced by computers and other new technologies. A growing emphasis on customization and a need to change products frequently in response to market demands has prompted some employers to reduce hierarchy and to rely instead on self-directed, interdisciplinary teams of workers. Organized labor, rooted in industries such as steel and heavy machinery, has had trouble responding to these changes. Unions prospered in the years immediately following World War II, but in later years, as the number of workers employed in the traditional manufacturing industries has declined, union membership has dropped. Employers, facing mounting challenges from low-wage, foreign competitors, have begun seeking greater flexibility in their employment policies, making more use of temporary and part-time employees and putting less emphasis on pay and benefit plans designed to cultivate long-term relationships with employees. They also have fought union organizing campaigns and strikes more aggressively. Politicians, once reluctant to buck union power, have passed legislation that cut further into the unions base. Meanwhile, many younger, skilled workers have come to see unions as anachronisms that restrict their independence. Only in sectors that essentially function as monopolies- such as government and public schools- have unions continued to make gains. Despite the diminished power of unions, skilled workers in successful industries have benefited from many of the recent changes in the workplace. But unskilled workers in more traditional industries often have encountered difficulties. The 1980s and 1990s saw a growing gap in the wages paid to skilled and unskilled workers. While American workers at the end of the 1990s thus could look back on a decade of growing prosperity born of strong economic growth and low unemployment, many felt uncertain about what the future would bring.

Man Killed in Sydney Shooting - Essay Example Local people are strictly prohibited to get into the area until the investigation process is in progress and police advice the people for not to come across the street and try to avoid it. However, even after several primary investigation process police is still unable to identify any criminals or suspects. As the shootout was held in the evening the police have decided to close the road from late evening. Even though the investigation is taking place still the criminals are still free and no one is yet arrested by the police. The case is in progress and the murderer is still undetected. Moreover, the increasing number of crime in Australia is affecting its social and political stability to a large extent. Thus, the local people are getting affected by the increasing criminal activities in Australia (The Australian, 2014). The Social Structure Theory mainly implies the relationship between various attributes of the society. The social structure theory is mainly based on the three modules those are a strain, cultural deviance theory, and social disorganization theory. The objective of these components of the theory is to provide support for understanding individual behavior towards the criminal behavior. In this context, the cultural deviance fits appropriately for the case. The cultural deviance theory is a combination of the social disorganization and strain theory.

Police, however, suspects that there might be some involvement of the mafia gang who are experts in this kind of activity as referred to in the case. The cultural deviance theory signifies that the upbringing or the family cu lture of a person can lead them towards the crime.  

How does the Welfare system negatively impact black males Research Paper

How does the Welfare system negatively impact black males - Research Paper Example cioeconomically weak fathers cannot fulfill the responsibility of raising their children in a normal, healthy, and positive environment when living conditions appear to be the most acrimonious for them. Therefore, the purpose of this welfare program targeting black American fathers is to identify such fathers who due to lack in resources, education, finance, and social support find themselves unable to connect with their children. Certainly proof is required to certify if such a program could be considered substantial or not and should African American fathers who lack resources be helped financially, educationally, and socially to help them connect with their children or not. For that purpose, this research paper strives to bring up evidence regarding what effects factors like incarceration, single parent households, and low socioeconomic status have on black males in America and what role do such factors play in estranging the suffering fathers from children. Often, children born in underprivileged black communities get to live without fathers, are exposed to myriad bad social experiences very often, and their connection with fathers is ultimately totally broken over time. â€Å"Father absence in the African American communities, across America, has hit those communities with the force of 100 hurricane Katrinas† (Jackson, cited in Kelly, 2007). Both parents need to be present in a child’s life during all those critical years when mental and emotional grooming starts and progresses. The welfare programs aim at rehabilitating the underprivileged fathers by supporting them in their efforts of finding employment and attaining self-sufficiency. An educationally poor father can seldom support a good job and maintain livelihood. In this regards, a range of programs inside and outside prison are also necessary for black incarcerated men to â€Å"prepare them for release, to make referrals and provide services when they return to t he community† (McKean, 2004, p. 5).
