Introduction to Social Science: Traditional Versus Modern Societies

Introduction to Social Science: Traditional Versus Modern Societies

Introduction
Throughout history; society has progressed to attain notable achievements despite impeding obstacles. Today, many diverse individuals enjoy a plethora of rights and freedoms that had not existed in the past. Change is essential since it fosters new opportunities and our understanding of society is much different than individuals who had lived prior to the industrial revolution. Tradition and modernity are two differing principles which continue to manifest in North American society. Across the world, there have been societies which have retained these traditional values and others which have shifted either partially or completely towards a modern society. There are a plethora of opinions in regard to this phenomenon, and this essay recognizes each viewpoint. In my paper, I will argue that elements of the modern capitalist society have enabled society to flourish due to its expansion in the economy,
emergence of the welfare state and the introduction of globalization. Furthermore, this paper seeks to compare and contrast the two different societies while highlighting their main principles.

The Contributions of Niels Bohr

The Contributions of Niels Bohr

Niels Bohr was one of the greatest scientists in the 20th century. He created a model of atomic structure and he established the foundations of quantum mechanics for which he received the Nobel Prize on December 10, 1922. In this following research paper I am going to write about the background of Niels Bohr, analyze his ground-breaking contributions, and look at the developments that followed from Bohr’s work, and how human society benefits from his work.

Savant Syndrome - A Gift or a Curse?

Savant Syndrome - A Gift or a Curse?

“I have been given the gift of solving complex engineering problems, but to pay for the gift I’m socially crippled”- John Robinson (Mechanical Engineer Savant).

I present that quote because I believe it speaks for everyone that has Savant Syndrome or is associated in any way with someone else who has it. Quotes like John’s are very similar to many quotes given by Savants during interviews or just randomly speaking to someone. I have been intrigued for some time with the study of Savant Syndrome and have been more interested when the majority of studies I see treat Savant’s as disabled people with “some random gift”. Through current studies I have discovered Savant Syndrome is not just simply genetic flaw, it can come out of nowhere and even be triggered by severe brain injury. To give an idea of how Autism affects the brain I included the actual brain scan of a person diagnosed with Autism. Autism is said to affect primarily the left side of the brain, which is exactly what this scan appears to show.

Molecular Marker Assisted Selection: A Vital Tool For Wheat Breeding

Molecular Marker Assisted Selection: A Vital Tool For Wheat Breeding

Wheat (Triticum spp.) is a cereal grain, cultivated worldwide. It is the second most-produced cereal after maize. The importance of bread wheat for human food requires continuous improvement of wheat quality and productivity. Genetic complexity impedes breeders to identify, map and trace useful genes associated with excellent traits for crop breeding. However, it gives potential opportunity to create diversity by introducing alien genes or chromosome segments. Molecular marker as assisted selection method here provide vital role in screening and mapping genes and traits of interest in populations. Both advantages and disadvantages of molecular markers for wheat breeding are discussed.

Background Paper for A New Framework for Carbon Emission Reductions

Background Paper for A New Framework for Carbon Emission Reductions

1.Introduction
The dangers of global warming are no longer restricted to polar bears. Climate change is fundamentally influencing many aspects of human life via changes in precipitation patterns, increased occurrences and intensity of droughts and floods, impacts on human health and settlements, food production, biodiversity, and fresh water supply. These trends are likely to exacerbate in the coming decades if we do not drastically change our greenhouse gas (GHG) emissions in the foreseeable future.

A changing climate is nothing new and has happened for millennia. However, the current human-induced global climate change is taking place much more rapidly than before and with levels of carbon dioxide (CO2) and other GHG concentrations in our atmosphere unprecedented in the last 650,000 years. In addition, we are experiencing temperatures that are at least among the highest of the past 740,000 years.

Critical Analysis of Nida’s Dynamic Equivalence Theory - Translation Theory Essay

Critical Analysis of Nida’s Dynamic Equivalence Theory - Translation Theory Essay

Abstract
This essay presents an analysis of Eugene A. Nida’s dynamic equivalence theory from the point of view of requirements for a good translation theory. In Nida’s theory, the new concepts of dynamic equivalent, equivalent effects and three-stage translating procedures made the theory so influential in the following century. Nida discarded traditional approach placing too many demands upon the reader to become informed about the original culture, approached translation from a scientific point of view and shifted the focus to the receptor’s response. After careful examination and analysis against each requirement, Nida’s theory is found to be theoretically satisfying and practically applicable.

A Heroine in the Structure of Life - An Essay on Biophysicist Rosalind Franklin

A Heroine in the Structure of Life - An Essay on Biophysicist Rosalind Franklin

In the year 1920 on the 25th of April science met one of its most prominent minds. Rosalind Franklin was born in Notting Hill London to a baker and was one of five children. In an age where the education of women was not considered necessary, she had a ready mind, so her parents sent her to one of the few girls schools in London; St. Paul's Girls School, where she quickly showed promise in science, Latin, and sports. It was during her time at the Girls School that she decided she would be a scientist. After the start of WWII the Franklin family helped to hide refuge Jews from Nazi’s in their home, all her life Rosalind was raised to understand the importance of life. After finishing her education at St. Paul's Girls School she went on to Newnham College where she finished her undergraduate in 1941, in 1945 she completed her doctorate at Cambridge University (Biography.com).

Bubble Formation and Endothelial Function Before and After Three Months of Dive Training

Bubble Formation and Endothelial Function Before and After Three Months of Dive Training

Poor decompression following diving leads to bubble formation in tissues and blood vessels which causes decompression sickness (DCS). Bubbles have been clearly shown to be the root cause of DCS, but often these “silent bubbles” go undetected. It has been shown that repeated diving exposures decrease the susceptibility to bubble formation. A single bout of physical activity prior to a dive has been shown to decrease detection of bubbles via Doppler system. It is possible that the endothelial function of the individual has improved with repeated diving therefore releasing a greater amount of Nitric Oxide (NO). Since a single dive inflames the endothelium, it is possible that dive training will adapt the endothelium and increase NO production. The aim of this research was to see if dive training will decrease bubble formation and enhance endothelial function.

Short Essay on the Causes of Deforestation

One cause of deforestation is air pollution. Over the years air pollutants accumulate in the trees’ cells and weaken them. They are then more easily harmed by insects, disease, and drought. As the trees’ becomes weaker their needles and leaves drop too soon and their roots cease to absorb water and nutrients. Trees that are already weak from other factors are more susceptible to air pollutants than healthy ones. In many countries, deforestation by air pollution is visible. ”More than half of the trees in the British Isles, Swiss Alps, and western Germany are dead or seriously damaged.” (Tesar 60).

Standby Power Generation - Applications and Transients

In today’s environment with a high reliance on reliable electrical power, it has become a common practice to include engine-generator sets in the design of new facilities. Their purpose is to provide power in the event of a utility power failure and, where local utility rate structures and policies make it a viable option, to reduce overall electrical energy costs. One of the major reasons for this emphasis on emergency/standby power has been the increased use of computers and digital controls in all aspects of commercial and industrial processes. Personal safety, production schedules, and in-process inventory are some of the items adversely affected by the lack of power integrity. It is the intent of this program to help you apply generator sets in a manner that will provide reliable power of the quality and capacity required by the end user.

What Really Matters in Commercial Agriculture

What Really Matters in Commercial Agriculture

According to the U.S. Census, the world’s population reached 6,761,657,535 in 2008. The population is now at its largest and is still growing with two hundred and forty-five babies being born every minute (“[How Many Babies]”). As the population grows, so does the demand for food. In “The Politics of Hunger,” by Paul Collier, he states “The solution must come from dramatically increasing world food supply” (Collier 2). As a result of the high demand, commercial agriculture was introduced globally back in 1996 (Collier 4).This involves genetically modifying crops by infusing them with chemicals and using fertilizers in their growth. Doing this enables crops to produce a greater supply of larger crops and in a short period of time. Commercial agriculture is the only solution to the food crisis and must be increased.

Interconversions Between Linear Viscoelastic Functions by Using the Relaxation-Creep Duality Representation

Abstract

Paper on the Environmental Process of Coastal Erosion

The environmental process of coastal erosion has long been the subject of environmental management; particularly because it directly threatens human assets and wellbeing over relatively short time scales. Coastal erosion is significant because 44% of the worlds population live within 150km of the coast (Cohen et al., 1997 cited in Brommer et al., 2009: 181), and with it millions of dollars worth of trade, tourism, assets and business. Many environmental processes need thorough identification of ecosystem services, a process of valueation which often hinders the application of urgently required management. However, with the vast value of coasts already acknowledged, we can examine how well this has translated into investment in the form of research and response. This essay will explore past approaches to coastal management, and its effectiveness in addressing the coast as an open system with complex human interactions.

Anthropology - Introduction to Culture

Anthropology - Introduction to Culture

As humans we are bound to have a biased opinion about not only ourselves, but our cultures. We always assume that if we are from a civilized culture we are superior than uncivilized third world countries. We then feel the need to alter their way of living instead of letting them live. The knowledge we gain, and our lavish ways of living does not make us superior, but rather unique. We fail to appreciate the knowledge we can gain from small- scale societies. Simplistic societies like the Rautes have much to offer us. They have become part of the society that prevails because of them. The lack of societies like this would cause the biodiversity and ecosystem in the areas that they live in to fail. The Rautes directly help farmers by eliminating monkeys that ruin their crops. Without the the Rautes society farmers would have to go in and eliminate the monkeys themselves. Not only do Rautes save farmers time, but they indirectly do their dirty work for them. They allow the farmers to provide food for children, women, and men.

Differences Between Science and Pseudoscience

Differences Between Science and Pseudoscience

A majority of people are very familiar with the word “science”. There is no doubt that science plays a crucial role in our life. However, it seems that not everyone can distinguish science correctly from non-science and pseudoscience. The following essay will present the differences between science, pseudoscience and non-science first, and then discuss three possible responses to the question that what we should do when there is a clash between scientific explanation and non-scientific explanation. The brief discussion related to the correct non-scientific explanation will present finally.

Assessing Microbial Risks from Land Applied Class B Biosolids Through Groundwater Pathway Under Wet Weather Events

Assessing Microbial Risks from Land Applied Class B Biosolids Through Groundwater Pathway Under Wet Weather Events

Abstract
Introduction
The exposure model is the most essential and complicated part of QMRA. Both model structure and parameter selections are crucial for the reliability of the results. To assess the biosolids-associated risks from groundwater pathway, the situation under rainfalls need to be accounted. The rainfall events may increase the resulting risks from biosolids by producing a large amount of water infiltrated in the soil and advancing the microbial transport significantly. The subsurface fate and transport model must take several crucial elements into account, including occurrence values of pathogens in biosolids, the potential routes of infection, the probability of human exposure to the source of the pathogen, as well as the amount that humans would ingest, and the virulence of the infectious agent (U.S. EPA 2000).

How Planet Models are a Simplified Representation of Some Aspects of the World - Ways Models Help or Hinder the Search For Knowledge

How Models are a Simplified Representation of Some Aspects of the World - Ways Models Help or Hinder the Search For Knowledge

In middle school, I was taught that electrons orbit the nucleus like plants orbiting the sun. I found it quite comprehensible, as I was familiar with the structure of the solar system, and I appreciated the elegance of this analogy. However, in high school, I learned that the planetary model was abandoned long ago, and I was introduced to a more sophisticated one: the quantum model. I wondered why my middle school teacher could have taught me the wrong thing. However, I later realized that if I hadn’t got used to the planetary model, I would never have understand the newer more complex one.

Types of Volcanoes

Abstract
How do you cause global damage to the Earth’s atmosphere due to natural activity? Can a volcano because it is a living gas chamber full of intense magma waiting to explode, but can one volcano do all this damage? This is what I am trying to find out. Where on the Ring of Fire does it have to be an eruption in order to cause the Earth to do such a thing or do it have to be multiple? How big of a volcano does it have to be? Can the volcano be underwater or overwater? How much lava and ash will have to be emitted in order for this to happen.

The Modulation of NADPH, NADH and A-Ketoglutarate in P Flourescens Exposed to Oxidative Stress

The Modulation of NADPH, NADH and A-Ketoglutarate in P Flourescens Exposed to Oxidative Stress
Introduction

Oxygen and Life

The metabolic processes such as respiration and photosynthesis have now been proven to unavoidably lead to the production of reactive oxygen species (ROS).1 The common feature of all known ROS species is their inherent capacity to cause oxidative damage to proteins, DNA, lipids and carbohydrates in-vivo. In that there is such widespread cytotoxicity due to the by-products of energy metabolism within the aerobe, elaborate and redundant non-enzymatic and enzymatic ROS detoxification mechanisms have evolved to enable aerobic organisms to combat this danger.

Integrative Function in the Auditory Pathway for the Perception of a 4 kHz 10 dB Sound

Introduction
In the perception of an incoming 4 kHz 10 dB sound at 0 azimuth angle, the ears act as transducers for transformation of acoustic signals into electrical signals. The physical characteristics, location and meaning of the sound represented by these signals and are processed by our brain. This task requires contribution of various components along the auditory pathway including the outer ear, middle ear, inner ear and our brain. This essay will critically evaluate the role each component plays in the process.

Self-Assembled Microspheres for Cell Encapsulation and 3D Cell Culture

Self-Assembled Microspheres for Cell Encapsulation and 3D Cell Culture

ABSTRACT

We outline here a simple method for combining peptide self-assembly with emulsion processing to produce spherical microgels composed of laterally associated -sheet fibrils. The extreme salt-sensitivity of -sheet fibrillization was a useful means for triggering the gelation of initially soluble short peptides into micron-scale particles within the aqueous phase of water-in-oil emulsions. Size control over the microgels was achieved by specification of blade type, speed, and additional shear steps. Microgels constructed in this way could then be embedded within other self-assembled matrices by mixing pre-formed microgels with un-assembled peptides and inducing gelation of the entire composite. In this way, spatially heterogeneous synthetic ECMs could be produced. The gels themselves were cytocompatible, as was the microgel fabrication procedure, enabling the embedding of cells within the microgels with excellent viability. Functional readout.

Does Nature Have a Larger Impact on Human Development Than the Environment?

Does Nature Have a Larger Impact on Human Development Than the Environment?

Nature versus nurture has been a continuing debate between scientists and is far from being settled. It is a challenge for scientists to come up with a true answer to whether a human is born with all of their traits or if the environment develops them. It is extremely difficult to study what genes are specifically inherited by a person and what aspects of control the environment has over those genes. The reason for this is because it is unethical to take a child out of its natural surroundings to test nature versus nurture.

Three Biochemical Processes Mediated by Bacteria That are Important in Environmental Engineering

Bacteria demonstrate diverse biochemical metabolic reactions. Describe three biochemical processes mediated by bacteria that are important in Environmental Engineering. How does a fundamental understanding of the microbiology of these processes assist in designing treatment systems for wastes and wastewater?

Introduction
This essay will look into three processes mediated by bacteria that are important in Environmental Engineering. Also look into how does a fundamental understanding of the microbiology of these processes assist in designing treatment systems for wastes and wastewater.

Clean water supplies can contribute greatly to good ecological health. Water is vital for life, but also an excellent carrier of toxic substances, micro-organism and pathogens which can lead to diseases and bad health. Bacteria have been an important existence to all life forms and are possibly our roots. Bacteria multiply and reproduce at incredible speed, hence more chances of mutations occurring. Bacteria can evolve and adapt to a new environment in little time. Due to this fact, different types of bacteria can be found everywhere, each adapted to its particular environment.

Paper on Water Resources

Water resources is a main issue I believe needs to be address to make the public aware just how serious our water usage is being threaten. Contaminated waters can cause health issues in humans, plants, and other species that live a marine life. Man has made a negative impact in our society when it comes to protecting our waters from harm. The BP oil spill in the Gulf Of Mexico was the latest example of man made mistakes that not only endangered our waters ,but also damaged the economy in the southern part of the country. The outcome of the tragedy was a ongoing cleanup effort that left damage to marine life endangering reproduction.

An Inconvenient Truth - Limits on the Greenhouse Gas Emissions

With the impact of global warming,Many countries have proposed to limit greenhouse gas emissions to protect the environment. It should not be mandatory for all countries to have a limit on their greenhouse gas emissions regardless of they are a developing country, because limit carbon emissions in developing countries is not fair and if developed countries do not take into account the low-carbon development in developing countries may be lead to more emissions.

The Use of Performance Enhancing Drugs - Social Trends and Economic Effect of Drug Consumption

Introduction

The use of performance-enhancing drugs, better known as “doping”, is a serious issue in sports and widely discussed in the media since a long time. Although it is considered to be unethical, these exogenous and often illegal substances like amphetamine or anabolic steroids are mostly done by athletes, who expect to artificially enhance their athletic performances. In 2007, the Italian anti-doping expert Allesandro Donati showed in his survey about the market for such drugs, that it had grown to a sales volume of approximately 15 billion € per year with a huge demand of 15 million consumers worldwide.

Labeling Prespective - Analyzing the Mentally Ill in Hong Kong

Use the Labeling Perspective to analyze the mentally ill in Hong Kong

Do you know what “mental illness” is? Nowadays, “mental illness” is a common word in the society. I believe you must have heard of this word. We can read and watch news about mental illness patients on newspapers and televisions. Most people do not want to have contact with those patients. They even prejudice them. In the following paragraphs, we will use the labeling perspective to explain more about the social problem of mental ill in Hong Kong and how to help those patients.

First, let’s read the following real case reported by Apple Daily on 11th February, 2011:

Pressures of Taking Global Actions to Protect the Environment

The pressure of taking global actions to protect environment intensifies recently (Low, 993), so identifying which group of countries should make more efforts become important. Generally, developing countries contribute more than developed countries on environmental issues. One of the problems is deforestation, which can be explained by population increase and industrial activities development, and occurs most in developing countries. Another problem is greenhouse gas emissions, which is due to the rapid economic growth in developing country. It will become even more serious without control.

Deforestation is one of serious environmental issues, which can most due to the developing nations. There are two main reasons that can explain it.

Discussion on the Use of Therapeutic Cloning to Repair Human Organs

Discussion on the Use of Therapeutic Cloning to Repair Human Organs

Is it ethically right to use therapeutic cloning in repairing human organs?

Abstract

Therapeutic cloning is the creation of a cloned embryo to provide stem cells for research and saving human lives. It is different from reproductive cloning as it is the embryos are not allowed to implant into a uterus to ultimately grow into a baby. In this essay I am going to discuss why therapeutic cloning is ethical. The main point which supports the use of therapeutic cloning is that it can save people who are in need of organs transplants. It is believed that it is ethical to carry on researching and finding out ways to save lives.

Genetic Engineering - How it is Used

What is Genetic Engineering?

Genetics is one of the most popular and has the largest potential subject which attracts many scientists devoted themselves to it nowadays. Genetic engineering which also known as genetic modification or recombinant DNA technology aims to change the inheritance of an organism. This artificial technology can change and amplify an organism’s genetic material in a way which can not be happened under natural conditions. It is an important branch of bioengineering. Today genetic engineering has gained a great achievement in many fields, such as agriculture, food, industry and medicine.

Understanding Time Travel - A Physics Essay

Understanding Time Travel - A Physics Essay

Time travel is a unique option that allows people of the universe to be able to travel forward in time and be capable of experiencing something they wouldn’t have even known that would have happened without time travel. Some people and physicists are pondering the concept of if you can’t move backward in time, even a little bit, does this mean people can move forward in time? The answer is not as clear as one would think. Some physicists say you can only move backward in time not forward. Others say you can move backward in time but also forward as well, with the possibility of entering a parallel universe. This means if you go too far backward in to this parallel universe, essentially you can mess up the regular world and the birth of certain people in your life.

The Chemistry Side of Forging a Sword

The Chemistry Side of Forging a Sword

The forging of a sword is deeply centered in chemistry. Swords have been an important part of our history as humans, playing a huge role especially during Medieval and Renaissance times in Europe. The strength of a sword was a deciding factor to a Medieval army's success; a brittle sword would be a man's death sentence. The sword is also a way of showing the owner's wealth by the adornment it carried. However, a good sword begins with the proper materials.

The Ocean and Our Lives - An Essay on Pollution

What is an ocean? According to the dictionary, it is “the mass of salt water that covers most of the earth’s surface.” Most people may say the exacr same line when they were asked this question. Furthermore, they might understand that the polluting of the ocean is something bad, but they do not understand what really happens even if the news reported the pollution of the ocean. The human beings made the problem. One magazine said, “In an average year, mankind dumps some 34 million gallons (130 million L) of oil into the oceans of the world” (Awake!). In another magazine, “Worldwide, an estimated $56 billion is needed annually to address this enormous wastewater problem” (Halweii). In the same article, he wrote, “The U.N. Environment Programme (UNEP) estimates that 46,000 pieces of plastic litter — including bits of packaging, cigarette lighters, plastic bags, and diapers — are floating on every square mile of the oceans, a figure that has increased threefold since the 1960s” (Halweii). There are many lots of reports that show human beings polluting the ocean every day, and the amount of pollution is enormous.

The Ayalon Cave and it's Impact on the Cave Ecosystem

The Ayalon Cave and its Impact on the Cave Ecosystem

In 2006, the Ayalon Cave was discovered in the Ramle, Israel. An area, located between Jerusalem and Tel Aviv. The cave was first discovered and explored by Prof. Amos Frumkin of the Hebrew University of Jerusalem geography department and his coworkers, behind a small opening made by a bulldozer during quarrying by the local cement factory. The cave system behind the opening consists of chambers and tunnels reaching a total length of about 2.5 km, and includes a room 30 m high with a diameter of 40 to 50 m, with an underground lake. The cave system dates back millions of years, and extends to a depth of 100 m beneath the surface of the quarry. The cave's surface is situated under a layer of chalk that is impenetrable to water. The underground lake is part of the Yarkon-Taninim aquifer, one of Israel's two aquifers, yet it is different in temperature and chemical composition from the main waters of the aquifer. The lake's temperature and salinity indicates that its source is deep underground. Sulfide is present in the lower layers of the water.

Essay on Ultrasounds and X-Rays and the Physics Involved

Essay on Ultrasounds and X-rays and the Physics Involved

In this essay I will explain about ultrasound and x-rays and talk about how they are put to use in the medical profession. I will not only talk about the physics involved when putting these technologies to work but also the dangers they may impose if not used correctly.

Ultrasound

An ultrasound is a medical imaging technique that basically uses sound waves (which are of a high frequency) and records its echoes. Just like what submarines use to located other ships or submarines (sonar) as well as what bats use to see in the dark. Ultrasound works in the medical profession by the ultrasound machine transmitting high frequency sound pulse though the body using a probe. The frequency of the sound is about (1 to 5 megahertz). The sound then travels though the body until it hits a tissue boundary for example between fluid and a soft tissue.

Essay on Education and Science

Education and Science in the Next Century

Education will be the challenge for the next century. It will need resources and imagination. It will have to explore new ways. Within that scheme science education is a central problem. Just because we may expect that science and technology will shape the future world or at least be strongly intergrowth with the life of people, their health, their jobs.

Science and technology are a special problem in pedagogy: they constantly move ahead. They produce new things which are directly used and need to be quickly understood and mastered to cope, for instance, with the needs of the job's market. But also science is expanding indefinitely: there is no limit, knowledge is always growing. It cannot be mastered by any encyclopaedic process. This situation is a clear burden on schools’ curricula. It creates a demand for continuous education, a process going on for life.
