Brain Development in Young Children - 696 Words

There are many stages that happen when a baby brain is developing. The first three years are what makes the brain responsive to external input. There first three years can capture more efficiently then it will be able to later on. The brain goes through three trimester when it is developing. The brain development is the major conductor for helping a young child learn and comprehend what they are doing. There are also ways that parents and teachers can help enhance the brain development for young children. The pregnancy period is also a main factor with the brain development. The reason for that is because they learn the voice of their mother from her reading. So when the baby is born the can recognize their mother by her voice. During the first trimester is the formation of neural tubes. About seven weeks after the neurons and synapse begin to develop in the spinal cord, which allows the fetus to make movement. In the second trimester is where the gyri and scili appear in the brain s urface. This process is called myelination. This allows the information to process faster in the brain. In order for the brain to achieve the same level of efficiency without myelination the spinal cord would have to be three yards diameter. The third trimester is the transitional period, which is the reflexes such as fetal breathing and responses to the stimuli. Also, during this period the cerebral cortex supports early learning. As they start to get older they are able to develop moreShow MoreRelatedThe Plasticity At A Young Age1693 Words   |  7 PagesThe brain is constantly changing and molding from new experiences.

Marx s Views On Private Property - 1157 Words

Introduction English philosopher John Locke and German philosopher Karl Marx seem completely opposed in their views of private property. While Locke believes that private property is a natural right, Marx believes that private property should be abolished. Throughout this paper, Locke’s and Marx’s individual philosophies on private property will be presented and examined. Ultimately, this paper seeks to show the similarities between these thinkers’ viewpoints on private property and demonstrate that Marx’s philosophies have some roots in Locke’s. Moreover, this paper will examine how these philosophies affected the course of social, economic, and civilizational process. Private Property and its Relation to Government and Society Locke saw the ownership of property an important natural rights, as well as fundamental to a good government and society. He believed that all citizens had a right toâ€Å"life, liberty, and property†, if they had the means to attain it (SOURCE). He discusses his theories of property in the Second Treatise of Government. He said that God gave man the earth to hold in common. However, once man adds labor to the earth it becomes their private property. When a man plows a field, for example, it becomes his and so too do the benefits (or the fruits) of this land. The main purpose of the government, for Locke, is to protect an individual’s private property. When a state of nature is in place, there is no way for an individual to ensure that their propertyShow MoreRelatedJohn Locke s Views On Private Property And Politics1133 Words   |  5 Pagesdifferent perspectives regarding private property and politics in society.

At the time of Second World War, many people came from various European countries and different parts of the world. In current time, one third of Australians were born in another country. This country is popular choice for tourists due the hotels, transport, culture, nightlife, food, events and festivals. The country is the most important tourism destination among the tourists. So, Australia is the country of multi culture. Immigration has helped the country to become a dynamic country. Political, social and economical situation Australia has federal constitutional parliamentary democracy so Australians elect parliamentarians for the federal parliament. They have voting rights and it is important for people to give vote. Once people reach 18 years of age, they are obliged to vote. The political situation of the country allows people to live with the freedom. Looking at the social and economic aspects of the country, people have their own personal welfare. For instance, local crime and public safety, food and health, rights to basic services, equality of opportunities as well as civil and personal liberties are the rights for Australians. Local culture The culture of Australia is western culture which is basically derived from Britain but it is influenced by the unique geography of Australian continent. The oldest surviving cultures of the country are Torres Strait Islander and Aboriginal people of Australia. The people in the country are basically open, laid back and direct. They generally say what they mean and are more individual and outgoing as compared to other culture. It is observed that more than three quarters of people in the country are living in cities and urban centers along the coast. Communication Communication is the important topic in the business world. In Australia, there are some aspects of communication which must be taken into consideration. It is observed that the Australians value directness over negotiation. While communicating in the country, Australians are not self promotional and in the business life, they show dedication and credibility. This is the normal part of their culture. The country has fair and direct way of communication. In the direct culture of Australia, people say clearly and briefly without adding lots of context. Along with this, they use some non-verbal communication styles so that the spoken message should be delivered with all the relevant information. When a person in Australia gives a message, he expects from the other person to understand the message completely. This reflects the effective business communication styles in Australia. Management style There is the casual atmosphere in Australia which is very important for the business. The Australian business culture is very much included with the opinion of the individuals. So, the culture has consultative style of management which includes open debate. Quite the different, it shows the professionalism and dedication of the Australians. Managers in country do not isolate themselves from other members in the business. Business culture of Australia Australia is the second most individualistic culture in the world after U.S. In the country, business culture is more relationship oriented. It is focused on establishing trust, relying and supporting on the important elements of the business. The work environment and business culture of the country is the consensus oriented. There are consensus oriented style rather than highly directive leadership styles. Senior managers generally consult with the subordinates while making the decisions in the business. In terms of doing business, Australians do not focus on having long-terms relationships with the people (Vidal-Suarez Lopez-Duarte, 2013). Openness There is the openness in the business culture of Australia. People are open and free to put their ideas and viewpoints for the business operations. There is the highly valued culture in Australia. People have traits of the openness and direct manners in which their daily lives are connected. Australians are educated and straight forward in their communications. They have string and confrontational opinions for others. They always value for the directness and respect those people who express their own beliefs and views. In the business context, Australians have new ideas and they are motivated to live discussion and debate (Singh, Joshi Mandhan, 2014). Individualism This is the unique character of the Australians and this is the way adopted by them to interact with other people in the society. Along with this, there is one more characteristics of individualism which must take into consideration that it focuses on the personal privacy of differentiate people from the public and focuses on the private life of people. Equality The Australian culture has the characteristics of quality. The country has the culture of equality where the differences in the status do not matter in the business. This culture in the society avoids the differentiation the people having high income and status. Thus culture includes mutual respect for each other. There is equality in the Australian society focuses on all the aspects of Australian life and business sphere. The Australians avoid academic qualifications, business success and personal achievements since this may perceived as arrange (Akanni, Ahammad, 2015). Difference with Singapore The culture of Singapore focuses on the long term working relations. It is observed that as compared to Australians, the managers of Singapore are more committed towards the long term relationship in business. In terms of cultural differences between Singapore and Australia, people in Singapore are candid, direct, and state to their points with the confrontational way. The approach of Singapore culture is pragmatic along with the ability to discuss any point. Along with this, there is the large difference in the business culture of Australia and Singapore in terms of the working hours. The working hours in Singapore are longer and more intense as compared to Australia. That can be a big cultural difference in the work culture of Australia and Singapore. In the Singapore, values are less among the people and they are focused on the business. On the other hand, Australians have high moral and values. Further, Singapore is more regulated and centrally controlled as compared to Australia . In day to day matters, things happen fast in Australia as compared to the Singapore. There are some differences between Singapore and Australia in terms of business culture. Because of the plenty of natural resources, the economy of Australia has competitive advantage in producing various products like dairy, meat and wine. Along with this, there are key exporters of minerals and coal, travel and logistics etc for the economic growth. On the other hand, Singapore is the small land area and there is the lack of resources but country has driven itself to innovations. In terms of business languages, Australia has no official language and English is spoken by most of the people in which 2.1 million people speak Asian language and 1.3 million speak European language. In Singapore, English is the business language and also used by people there. Most of the Singaporeans have received formal education. Hofstedes cultural dimensions Hofstedes dimension of culture for the organizational research was carried out by the Greet Hofstede. This dimension can be used by various foreign companies while going to expand the business in the Australian market. There are five key dimensions by which the organization can analyze the culture of Australia. Power distance This dimension focuses on the extent by which employees have low power in the company and organization feel that the distribution of the power is not equal. The unequal distribution of power should be noticed by the organizations in the Australian business culture. The culture of Australia has high level score in the power distance index as the managers have equal rights and powers. This is an appropriate culture for the companies to operate the business. Individualism This dimension focuses on how people are converted in to various groups. If the individualism side is focused by the company then it means that people have to take care of themselves and their family also. There are no strong relations between individuals. If the organizations focus on the side of collectivism then it means groups are formed since their births and they have strong connections. In Australia, the culture is more individualism as compared to the collectivism. They combine the needs of individuals to the welfare of society. The problems of industry are handled by Australia by adopting the approach of individualism which is effective for the organizations for the successful business operations (Alkailani, Azzam Athamneh, 2012). Masculinity It focuses on the distribution of the work among the genders of the society. This can be the issue of the society related to the rights of women. This can be the issue for the companies to manage the business in the Australian market. The culture of the company depends upon the culture of the country. In the Australian context, women are free to select their career options. They are equally contributing in the business as men are doing. There is the culture of openness which would be beneficial for the organizations that are going to enter in the Australian business culture. The culture of Australia has high score in the dimension of masculinity (Tang, 2012). Uncertainty avoidance index This dimension focuses on the degree of culture of the specific country to make the member either feel relaxed or uncomfortable in the situations. There are two ways to avoid uncertainty of culture i.e. avoid culture or accept uncertainty in the culture. By imposing some strict laws and regulations, the uncertainty in the Australian culture can be avoided (Hofstede, 2011). Long term orientation This is the dimension which is focusing on the taking some interviews of some of the Australian scholars. It is said that the western culture is short term oriented which means people have values some traditions to complete all their social obligations. The culture in Australia is long term oriented which is carefulness. The people in Australia use their capability to accomplish their work and objectives in the business culture. People are using western culture to enhance their capability to get success in the business culture (Parente, Baack, Hahn, 2011). Strategies by foreign companies Based on the above discussed model, it is observed that the culture of Australia is open, aggressive and full of value along with the other aspects like working relationships and cooperation. There is the combination of various cultures which attract the organizations to operate the business significantly. Australia has high level of power-distance factor which is the key cultural trait of the country. This factor reveals that there are strong relationships between managers and employees in the organizations operating in the country. To stay effective in the Australian market, foreign companies need to have strategic business plans based on the practical experiences, understanding and insights. Further, to balance the risk, compliance outcomes and taxation, they should have effective business structures. Companies should have existing companies in the Australian market for the easier entry in the market. This cultural aspect of Australia makes the effective market for the organizations to operate the business. Culture of the country focuses on the power and prestige based on the western European culture. People on the high authority try to do their best and impact the subordinates so companies must set some directions for the effective business operations. Australians are hard working and dedicated people so, companies can focus on hiring of the employees so that limited resources can be used effectively (Kragh, 2012). Conclusion Based on the above analysis, it is observed that Australia is the suitable country for the business expansion. In terms of cultural differences between Singapore and Australia, people in Singapore are candid, direct, and state to their points with the confrontational way. Communication is the important topic in the business world. In Australia, there are some aspects of communication which must be taken into consideration. It is observed that people in the country like to do direct communication rather than negotiations. Having a varied workforce is increasingly being recognized within the organization as helpful in improving the performance of the organization, and also a crucial that organizations can focus and solve this. Australia is the country of multicultural factors and it is considered as the politically safe country among the organizations. Further, in the business context people in the country use their capability to accomplish their work and objectives in the business cul ture. They are influenced western culture to enhance their capability to get success in their business operations. Further, the political situation of the country allows people to live with the freedom. Looking at the social and economic aspects of the country, people have their own personal welfare. It is also observed that people in the country are not self-promotional. They communicate directly at any point in the discussions and debates. In the business culture of Australia, people are dedicated towards their work which is helpful for the foreign companies to gain profit in Australian market. Based on Hofstede model, it is analyzed that there is the culture of openness which would be beneficial for the organizations that are going to enter in the Australian business culture. At last, it can be said that the Australian culture is individualism and Australians do not form groups while operating the business. They only form the groups while focusing on the welfare of the society. It is observed that there are various cultural traits in Australia which make the country attractive for doing busine ss. The existing cultural aspects attract various foreign direct investments to expand their business in the country. References Akanni, M. and Ahammad, M. (2015).

The Basics of the Electron Transport Chain Essays (911 words)

The Basics of the Electron Transport Chain Article Summary:The electron transport chain is the most complex and productive pathway of cellular respiration. Here's a straightforward, simplified explanation of how the ETC works. All living things run on energy. If the organism is a plant or autotrophic microbe, the energy comes from sunlight. For all other forms of life, energy is extracted from nutrients through the reactions of metabolism--cellular respiration. Cellular Respiration the Electron Transport Chain Regardless of whether the original form of energy is sunlight or food, it must ultimately be converted to the cellular energy currency of adenosine triphosphate (ATP). or most organisms, this conversion is accomplished though cellular respiration, a series of biochemical pathways in which glucose (asugar) is broken down and the energy extracted is converted to ATP. The pathways of cellular respiration include: 1. glycolysis, 2. conversion of acetyl-CoA, 3. Kreb's cycle 4. electron transport. Electron transport is the most complex and productive pathway of cellular respiration. Duringaerobic respiration, the ETC produces 34 of the 38 ATP molecules obtained from every molecule of glucose. or most organisms, this conversion is accomplished though cellular respiration, a series of biochemical pathways in which glucose (asugar) is broken down and the energy extracted is converted to ATP. Where the Electron Transport Chain Is Located Electron transport requires a membrane in order to work. Inprokaryotic cells, those of bacteria and bacteria-like Archaeans, electron transport takes place in the cell's plasma membrane, in folded areas called mesosomes. For most organisms, this conversion is accomplished though cellular respiration, a series of biochemical pathways in which glucose (asugar) is broken down and the energy extracted is converted to ATP. The pathways of cellular respiration include: 1. glycolysis 2. conversion of acetyl-CoA 3. Kreb's cycle 4. electron transport. Electron transport is the most complex and productive pathway of cellular respiration. Duringaerobic respiration, the ETC produces 34 of the 38 ATP molecules obtained from every molecule of glucose. Whichever type of membrane houses the cell's electron transport chains (plasma membrane, inner membrane of mitochondria or the tylakoid membrane of chloroplasts)cells have many ETCs running continuously, to produce the ATP energy required for cells to survive and thrive. How the ETC Works Most of theATPmade incellular respiration comes from the stepwise release of energy, of a series of oxidation-reduction reactions between molecules embedded in the plasma membrane(prokaryotes)or mitochondria(eukaryotes). It is easiest to understand how electron transport works by dividing this process into three main events: 1.Oxidation Reduction Reactions During glycolysis, synthesis of acetyl-CoA and Kreb's cycle, the electron carriers NAD+ and FADH are reduced to form NADH and FADH2 respectively. These molecules are like little rechargeable batteries, and when NAD+ and FADH are reduced, this means that they accept and carry electrons and hydrogen ions (H+), potential energy that can be used later in cellular respiration. In the electron transport chain, these electron carriers are oxidized, transferring their electrons to the carrier molecules embedded in the ETC membrane. In aerobic respiration, these electrons are passed from one carrier molecule to another in a series of oxidation-reduction reactions, and ultimately to the final electron acceptor, oxygen (O2), that combines with hydrogen, resulting a water (H2O), a metabolic waste product. 2.Creation of Hydrogen Ion Gradient The energy from each electron being passed down the chain is used to pump a proton (H+) through each carrier molecule, from one side of the membrane to the other. This creates a proton gradient, a type ofconcentration gradient(difference in concentration of a substance between two sides of a membrane), and gradients are potential energy available for cellular work. 3.Phosphorylation of ADP(The payoff!) The hydrogen ions (H+), on the side of the membrane where most concentrated, will eventually flow back across the membrane, down the proton gradient, through anenzymecalledATP synthase. As each H+ moves back across the membrane, the enzyme ATP synthase phosphorylates (adds a phosphate to) adenosine diphosphate (ADP) to make the high energymolecule ATP, which can be used for many different energy-requiring reactions throughout the cell.
