External trade in cyprus during late bronze age Essay

External trade in cyprus during late bronze age - Essay Example External trade of Cyprus included export and import to and from its neighbouring countries, such as; Egypt, Anatolia, Syria, Levant and Palestine. These trading ties caused the island to have a substantial influence in the region. Foreign trades and resulting ties with the neighbouring countries made Cypriot economy quite significant during the Late Bronze Age. Development of these external relations at different phases will be investigated in a brief manner. This investigation includes the effect of migration and subsequently the transfer of Mycenaean skills, pottery making with the variety of styles and industry of ship manufacturing. Exported potteries and the underlying low quality limited its use to only ointment and oil containers. The paper discusses foreign trade of Cyprus, resulting relations with the trading partners, and its economic, social, and cultural impacts on Cyprus. Cyprus Role in Trading during the Late Bronze Age During the Late Bronze Age, Cyprus had been one of the most significant locations in the Mediterranean trade route; however, it couldn’t compete in popularity with its adjacent wealthier countries. There are several reasons for lacking importance, such as, insufficient information about Cyprus due to the fact that it was not mentioned enough in the written records about Late Bronze Age, and that it was geographically separated from other important nations. Major way of learning about the condition of Cyprus in late Bronze Age is to investigate its foreign relations through the archaeological remains and written texts from that era. Archaeological and textual evidence provide great insight when it comes to investigate and comprehend about the foreign trade in Cyprus during late Bronze Age.1Knapp explains and demonstrates the existence of politico-economic elites in Cyprus during Middle and Late Bronze Age through evidence (qtd. in Knapp 151). Amarna letters of Alashiya suggest that Cyprus had become an influential and affluen t kingdom at least by the 14th century BC. Ruler of the time considered himself on an equal level with Egyptian Pharaoh. This perception may link to the use of salutation, ‘my brother’.2 Cypriot rulers used state agents (called tamkar) in order to carry out foreign trade on massive level. Cyprus Exports Due to disintegration in the Aegean and eastern Mediterranean, Cypriot economy started to become recognized throughout the eastern Mediterranean and export of goods started. Particularly, this recognition boosted the copper production and trade. On Cyprus, ethnic elements of Aegean and Levantine were combined with Cypriot population. Moreover, the capabilities of industrial work started mounting.3 Copper According to the information from textual evidences from Late Bronze Age Cyprus, copper was the central and most exported item from the island during 13th and 14th century B.C. One of the countries that imported the Cypriot copper was Egypt. Moreover, referring to the be liefs in Egyptian texts, such as Amarna letters, Karageorghis (1975) highlights the presence of several mining areas in Cyprus, such as, Troodos foothills in Enkomi. Copper was exported as a major item to mould into weapons during battles while most weapons were made in Aegean. In addition, Cyprus (Enkomi) had huge supply of

Chapter Questions From Global health 101 richard skolnik book - Essay Example Global health is the science that prioritizes health improvement and equity in the global context (Skolnik 7). Medical approach focuses on the individual while public health focuses on the population. medical approach is a personalized service while public health is a public service. Medical approach focuses on diagnosis of the ailment, treatment and care of the individual while public health focuses on prevention and health promotion in the society (Skolnik 7). Millennium development goals are a crucial part of a country’s development effort. The nations declared to meet the goals by 2015. The goal to reduce child mortality, improve maternal health and combat disease are related to health (Skolnik 10). The keys to eradication of smallpox include advances in technology, cooperation between global health actors and government commitment. The lesson learnt is leadership and commitment are key to a successful global health program (Skolnik

Stakeholders Project Organizations

Stakeholders Project Organizations To address the theme of project requirements, carry out research and, from your findings, draft Clearly structured notes that explain what is: †¢ Meant by the terms primary, secondary and tertiary stakeholders. †¢ The purpose of a scope document and what sections it should contain. Stakeholders Introduction:Stakeholders are anyone who has an interest in the project. Project stakeholders are individuals and organizations that are actively involved in the project, or whose interests may be affected as a result of project execution or project completion. They may also exert influence over the projects objectives and outcomes. The project management team must identify the stakeholders, determine their requirements and expectations and to the extent possible, manage their influence in relation to the requirements to ensure a successful project. Project Project Stake holder Project management Project Support Project Manager How a Stakeholders directly involved in a project Figure : The Relationship Between Stakeholders and the Project There are three kinds of stakeholders are involved in a project they are ivolved in a project internally or externally like that . Primary stakeholders Secondary stakeholders Tertiary stakeholders Primary stakeholders Primary stakeholders are those people and groups eventually affected by the project. Who expect to benefit from or be negatively affected by the change of project. In most projects primary stakeholders will be categorized according to socio-economic assessment. Thus, primary stakeholders should often be divided by gender, social or income classes, occupational or service user groups Primary stakeholders a direct link with the business- Customers. Suppliers. Secondary stakeholders: Secondary stakeholders are those with an intermediary role. They can be divided into funding, implementing, monitoring and advocacy organizations, or simply governmental, NGO and private sector organizations. Secondary stakeholders arent exactly participating customer and suppliers. Who is indirectly affected by the project plan. Forestry companies Landowners and or residents not inside the protected area but near Tertiary Stakeholders: Tertiary Stakeholders are those who are not involved or affected, but can influence opinions either for or against. Tertiary- can still have an influence, but are not involved or affected, but can influence opinions either for or against Those indirectly affected by the program neighborhood organizations, academic institutions, elected officials, advocacy groups, professional associations, skeptics, opponents, and staff of related or competing organizations. Local opinion leaders Local media Ecology departments of universities, research institutes etc. Scope Document Introduction: The scope document is a common term for at all document that refines and defines the requirements aspect of the triple constraint of time, cost, and requirements. In this general sense, it provides an overview of what the project is supposed to accomplish and clarifies how those accomplishments will be achieved. It may also provide the team members, customer, and project manager with insight on what is specifically not in the scope. Section contain This section summarizes some of the business issues around the project, including profiles of major customer categories, assumptions that went into the project concept, and the management priorities for the project. Vision Statement. History of project (Before) Assumption Risk Stakeholder User Vision statement: It is important to a project manager vision and scope document. It is also one of the easiest to execute. A project faces some problem when a project run a good vision and scope document will help in this time History of project (Before) History of project section contains a summary of the problem that the project will solve. It should provide a brief history of the problem and an explanation of how the organization justified the decision to build software to address it. Assumption This is the list of assumptions that the stakeholders, users or project team have made. the rest of the vision and scope document should be ready before the Delphi meeting and used as the basis for estimation. Risk It should be generated by a project teams brainstorming session. It could include external factors that could impact the project, issues or problems that could potentially cause project delays or raise issues. User This is a bulleted list of the users. As with the stakeholders, each user can either be referred to by name or role however, if there are many users, it is usually inefficient to try to name each one. The needs of each user are described. Task -2 To address the theme of how to grasp and communicate the â€Å"big picture† (a higher level view of the project overall, rather than a lower level view of, say, tasks for team members) carry out research and, from your findings, draft clearly structured notes that explain the benefits of visual forms of communication compared to, say, text or speech. Provide examples of the following visual forms of communication to show that you understand how they work and what information they contain: †¢ Lifecycle models †¢ Activity networks †¢ Mind maps Give a written explanation of how each of these methods may be used to communicate key ideas in a project. Introduction: Planning and estimating a project has never been easy. All projects have certain characteristics in common. They all have a beginning and an end. In other words, they do not continue on forever. Projects result in the creation of one or more deliverables. Projects also have assigned resources either full time, part time or both. There are other characteristics as well. All organizations can have projects. Projects can include building a house or office building, planning and executing a marketing campaign, upgrading desktop operating systems, installing a new phone system, developing an IT business application, etc. Throughout the course of a project the plan always changes due to certain events, Such as a change in the requirements. In order to support these frequent changes, a Good planning process is essential. It should involve Reducing Risk Reducing uncertainty. Conveying Information to the customer helps support better decision Life cycle models are: There are three kinds of life cycle model Waterfall model V Model Spiral model Waterfall model But I like waterfall model instance of V model and spiral model. It easy to dived into isolated stage. Which is perfect for project because one stage complete another stage started .so it is sure that the stage is complete. Each stage realize on when previous stage complete. Every stage has a miles stone. It is easy to know about a project to se Waterfall model because it has various stages V model: I cont like v-model because of: -emphasize on testing. Time consuming Waste money because of taste in all phases. Spiral model: its difficult to represent its not understandable to project team.

Often considered the classic approach to the project development life cycle, the waterfall model describes a development method that is linear and sequential. Waterfall development has distinct goals for each phase of development.. Once a phase of development is completed, the development proceeds to the next phase and there is no turning back. Advantages / Disadvantages Most-widely used process model Controls schedules, budgets documentation Tends to favor well-understood system aspects over poorly understood system components Does not detect development areas behind schedule early in the lifecycle stages. Business Requirement: what is requiring in a business to do met in order to successes of a project.Establishes the components for building the system, including the row matatiels of a project and other necessary components Analysis: in analysis stage of a project a project manager is accept the all knowledge of a project how to solve it when its solved (project). Design: The design defines the major components and the interaction of those components, but the design does not define the structure of each component. It is determine the external interfaces and tools to use in the project. Code test: Implements the detailed design specification this only for code and Determines whether the project meets the specified requirements and finds any errors present in the code. System acceptance test: Acceptance testing is conducted within the testing area .its purpose is to allow the customer to confirm that the complete system. A detailed acceptance test plan is produced prior to testing which identifies the test to be conduct. Mind map A Mind map which represent a project with a graphics. Mind map is a diagram used to represent words, ideas, tasks or other items linked to and arranged radically around a central key word or idea. It is used to generate, visualize, structure and classify ideas, and as an aid in study, organization, problem solving, decision making, and writing. Mind mapping, on the other hand, is a more intuitive way to manage projects, particularly if you have a lot of responsibilities and its easy to let something slip if its not right in front of you Mind map show the level Strategic, Tactical, Operational And who is responsible for a particular work of a project. Activity network Activity Networks is one of the most popular planning techniques. However, the activity networks diagrams have since been applied to activity planning for a wide range of projects. The approach is very scalable, enabling it to be applied effectively to the planning of activities spanning even a very short time frame. The activity network is a diagram that represents the activities required and their inter-dependencies, their start and finish dates and the time necessary for their completion. The resources required for each activity are also included on the diagram. Activity Networks are made up of a series of activity boxes, each of which depicts a discrete activity or task. It is easy to know of a project details by using activity network such as Early Start Time: Est. represent of the start time of a project Duration: How long time the project continues. Early finished time: when the project complete Activity description: this is which task is depends other task. Last Start Time: Last finished time minus Duration Last finished time: Last Start Time of succeeding activity Float Critical Path: once the resources required to complete each activity have been identified and the activity network updated to reflect these, then the start and finish dates can be added. With the shape and size of the planned area of work now visible, the total cost of the resources can be calculated. There will always be a critical path running through any project, from the first activity to the last. The critical path is defined as that series of activities that have zero float. The concept of float is central to critical path analysis, as it represents the ability to schedule an activity, or sequence of activities, within a flexible time slot rather than having to perform it immediately. This enables the more efficient management of resources across all of the activities in the network. How to calculate Float of a project Reading through activity networks from left to right gives the total duration of the planned work. Reading back through the network, subtracting each duration shows those activities that have any spare time. This spare time, known as float, is a very useful concept in relation to resource scheduling and smoothing. Float identifies parcels of time that can be used to introduce flexibility into the planned work, enabling the more efficient use of the available resources. Summary: project Lifecycles model which represent the Controls schedules, budgets documentation with graphics about a project .Activity Network which is needs for time management of a project such as est,eft lst,lft float,critical path etc, Mind Map It is used to generate, visualize, structure and classify ideas, and as an aid in study, organization, problem solving, decision making, and writing. Task-3 On the theme of team selection and management, carry out research and, from your findings, draft Clearly structured notes on the team working theories devised by: †¢ Tuck man †¢ Belbin †¢ Myers-Briggs Write a summary of how knowledge of each theory might assist a project manager in the selection and development of an effective project team. Write notes that show how to assess the risk of team failure, using a risk matrix to document at least TWO possible risk scenarios, such as loss of key personnel or infighting between team-mates. Summaries the contingency plans you would call into effect, if the risks were realized. 1700 SUMMARY of Tuck man theory: Tuck man model explains that as the team develops maturity and ability, relationships establish, and the leader changes leadership style. Beginning with a directing style, moving through coaching, then participating, finishing delegating and almost detached. At this point the team may produce a successor leader and the previous leader can move on to develop a new team. Tuck man theory basically consists of four thing Forming Storming Norming Performing How to create a project group Storming 2 Forming 1 Performing 4 3 Norming Forming In the beginning step of a project which is forming the team is assembled and the task is allocated Firstly. Team members tend to behave independently and although goodwill may exist they do not know each other well enough to unconditionally trust one another. Time is spent planning, collecting information and bonding. Storming The second step of a project which is Storming The team starts to address the task suggesting ideas from a project. Different ideas may compete for ascendancy and if badly managed this phase can be very destructive for the team. Relationships between team members will be made or broken in this phase and some may never recover. In extreme cases the team can become stuck in the Storming phase. If a team is too focused on consensus they may decide on a plan which is less effective in completing the task for the sake of the team. This carries its own set of problems. It is essential that a team has strong facilitative leadership in this phase. Norming The thread step of a project which is Storming in Tuck man model As the team moves out of the Storming phase they will enter the Norming phase. This tends to be a move towards harmonious working practices with teams agreeing on the rules and values by which they operate. Team leaders can take a step back from the team at this stage as individual members take greater responsibility. The risk during the Norming stage is that the team becomes complacent and loses either their creative edge or the drive that brought them to this phase. Performing The four step of a project which is performing in Tuck man model Not all teams make it to the Performing phase, which is essentially an era of high performance. Performing teams are identified by high levels if independence, motivation, knowledge and competence. Decision making is collaborative and dissent is expected and encouraged as there will be a high level of respect in the communication between team members. Summary of Myers-Briggs theory: The Myers-Briggs personality typology, unlike some other typing theories such as the Enneagram or Four Temperaments, uses a combination of several aspects to arrive at a composite type, based on the interaction and relative weight of different behavioral and attitudinal factors. The types are expressed as combinations of four letters, as follows: E or I (Extravert or Introvert) S or N (Sensing or intuitive) T or F (Thinking or Feeling) J or P (Judging or Perceiving) Summary of Belbin theory: The term Team Roles was first coined by Dr Meredith Belbin, but is now used more generically to describe team types. A Team Role is defined by Meredith Belbin as: A tendency to behave, contribute and interrelate with others in a particular way. It is usually written Team Roles, but can also be found as teamroles or team-roles. Belbin Team Roles improve self-knowledge and understanding among individuals and teams. Team Roles depict a current behavioural pattern ,Preferences arent fixed, since many factors can influence behaviour, whether a new job, promotion or circumstances outside work. Co-ordinator Shaper Resource Investigator Company worker Monitor evaluator Team worker Completer finishers Specialist Co-ordinator: The co-ordinator is a person-oriented leader. This person is trusting, accepting, dominant and is committed to team goals and objectives. The co-ordinator is a positive thinker who approves of goal attainment, struggle and effort in others. Shaper: The shaper is a task-focused leader who abounds in nervous energy, who has a high motivation to achieve and for whom winning is the name of the game. Resource Investigator: The resource investigator is someone who explores opportunities and develops contacts. Resource investigators are good negotiators who probe others for information and support and pick up others ideas and develop them. Company Worker: Implementers are aware of external obligations and are disciplined, conscientious and have a good self-image. They tend to be tough-minded and practical, trusting and tolerant, respecting established traditions. Team worker: Team workers make helpful interventions to avert potential friction and enable difficult characters within the team to use their skills to positive ends. They tend to keep team spirit up and allow other members to contribute effectively. Specialist The specialist provides knowledge and technical skills which are in rare supply within the team. They are often highly introverted and anxious and tend to be self-starting, dedicated and committed Risk of Team failure Diagnosing Team Failure Teams are put together to combine the knowledge and expertise of team members, this helps to gain greater strategic thinking and enhanced creativity in business solutions. When teams fail to perform as expected, an attempt is usually made to pinpoint and blame the people responsible. However, the answer doesnt always lie in replacing the team or firing the ‘scapegoat but in answering the question, ‘what went wrong with the group as a whole and why? Unless we make an attempt to identify the underlying causes, its unlikely the solution will be found. Factors Identifying Six Common Problem Areas No Trust Between Team Members When team members dont trust each other or are suspicious of each others motives, the end result is a team that is not cohesive in its approach. Ineffective Interaction and Unproductive Team Meetings All the complexities of team dynamics come to the fore at the meeting. The meeting is one of the most critical aspects of the team process with strategies and innovative solutions to problems emerging during this time. Poor Role Clarity Role clarity is a must in a team situation. When roles are not clearly defined, this can lead to conflict and confusion on tasks. Losing Focus of Business Objectives If you dont know where you are heading, how can you get there!? At times a team fails because the goals are unclear to the team members. Faulty Analysis of Market Conditions and Flawed Company Policies At times a team can fail due to uncertainties in market conditions and an inability to read the signs of change. Poor Time Management A team should plan its goals and activities whilst keeping time constraints and deadlines in mind, otherwise their efficiency level in managing and implementing a task can Risk Matrix A Risk Matrix is a tool used in the Risk Assessment process, it allows the severity of the risk of an event occurring to be determined. http://www.databasepublish.com/solutions/project-services/risk-management The identified risks are collected into a Risk Matrix. The Risk Matrix includes the rating of severity, mitigation strategy, owner and contingency plan for each risk. These proposed actions are formulated to address the risks that can be avoided upon implementation of a mitigation strategy. For example Impact Probability High No Trust between team member High Poor Role Clarity High Poor Time Management Medium Faulty Analysis of Market Conditions and Flawed Company Policies Law Ineffective Interaction and Unproductive Team Meetings High H/H Mitigation/Contingency Required H/H Mitigation/Contingency Required H/H Mitigation/Contingency Required H/M Mitigation/Contingency Required H/L Mitigation/Contingency Recommended Midium M/H Mitigation/Contingency Required M/H Mitigation/Contingency Required H/H Mitigation/Contingency Required M/M Mitigation/Contingency Recommended M/L Mitigation/Contingency Optional Low H/H Mitigation/Contingency Required H/H Mitigation/Contingency Required L/H Mitigation/Contingency Recommended L/M Mitigation/Contingency Optional L/L Mitigation/Contingency Optional Probability / Impact Ranking Chart for Risk Matrix of a project The company or organisation then would calculate what levels of Risk they can take with different events. This would be done by weighing up the risk of an event occurring against the cost to implement safety and the benefit gained from it. Contingency Introduction:A project contingency or management reserve is an amount the consultant or the contractor may want to include the unexpected resources that may be overlooked or tasks that may have to be redone because they might not work for the first time. Contingency provision is to cover the elements of unforeseen minor changes in the technical and design specification. Contingency Plan: A defined set of tasks agreed upon by appropriate members of the Project Team that will be undertaken to manage the Project Team in the event the Risk occurs, roughly equivalent to an organizations various Disaster Plans. Tasks should be assignable to a single accountable resource. Given the substantive effect that the Risk is judged to have on the Project, the Contingency Plan may be relatively short with the realization that if it is invoked, it will ultimately give rise to a larger Project Plan detailed elsewhere. Otherwise, the guidelines for granularity etc. of individual tasks are identical to those described for the Mitigation Strategy. All risks with a must have an associated Contingency Plan If the decision has already been made to cancel the project if the Risk occurs, the Contingency Plan should stat

WEB DUBOIS WEB Dubois was born and raised in Barrington, Massachusetts. After high school and with the help of friends and family, and a scholarship he received to Fisk College (now University), he eagerly to Nashville, Tennessee to further his education. This was his first trip south. And during his stay there, his knowledge of the race problem became clearer. He saw discrimination in ways he never dreamed of, and developed a determination to expedite the emancipation of his people. Consequently, he became a writer, editor, and an impassioned orator. And in the process, acquired a belligerent attitude toward the color bar. While he was teaching an Atlanta University, Dubois wrote about and studied Negro morality and Negro urbanization. During this period a controversy grew between DuBois and Booker T. Washington, which later grew into a bitter personal battle. Washington argued the Black people should temporarily forego "political power, insistence on civil rights, and higher education of Negro youth. They should concentrate all their energies on industrial education." DuBois believed in the higher education of a "Talented Tenth" who through their knowledge of modern culture could guide the American Negro into a higher civilization. (DuBois’ Dusk of Dawn). When Dubois began to solicit help for â€Å"organized determination and aggressive action on the part of men who believe in Negro freedom and growth†, twenty-nine men from fourteen states answered the call in Buffalo, New York. Five months later in January of 1906 the "Niagara Movement" was formed. Its objectives were to advocate civil justice and abolish caste discrimination. Though they were criticized for their radicalism, this was the first significant black organized protest movement of the twentieth century. The downfall of the group was attributed to public accusations of fraud and deceit engineered presumably by Washington advocates. In 1909 most members of the Niagara Movement merged with some white liberals and thus the National Association for the Advancement of Colored People (NAACP) was born. DuBois was not altogether pleased with the group but agreed to stay on as Director of Publications and Research. He was also editor in chief of its publication â₠¬Å"the crisis for more than 20 years. He used his mighty pen to denounce racial injustice all over the country and grew more and more popular. This period marked the height of DuBois' popularity. The Crisis magazine subscription rate had grown from 1000 in 1909 to over 10,000 in May of 1919.

The Interaction Between Heredity and Environment

Have you ever wondered why people resemble their parents? The answer to this and other questions about inheritance lies in a specialized branch of biology called genetics. Geneticist found that most aspects of life have a hereditary basis and that many traits can appear in more than one form. For instance, human beings have blond, or red, or brown, or black hair. They may have one of several different types of blood, one or several colors of skin. Their ear lobes may be attached or free. They may or may not be able to manufacture certain enzymes.Some of these traits are much more important to the life of the individual than others, but all of them are hereditary. The geneticist is interested not only in the traits of man but in those of all other organisms as well. The study of inheritance depends on the differences as well as the similarities between parents and offspring over several generations. Heredity is very complex, and a geneticist cannot possibly analyze all the traits of a n organism at once. Instead, he studies only a few traits at a time. Many other traits are present.As the geneticists work out the solution to each hereditary mystery, the geneticist must not forget that all organisms live in a complex environment. The environment may affect the degree to which a hereditary trait develops. The geneticist must try to find out which of the many parts of the environment may affect his results. The factors must be kept as constant as possible by using controlled experiments. Only then can he tell that the differences observed are due to heredity. Heredity determines what an organism may become, not what it will become. What an organism becomes depends on both its heredity and environment.The modern science of genetics started with the work of Gregor Mendel. He found that a certain factor in a plant cell determined the traits the plant would have. Thirty years after his discovery this determines was given the name gene. Of the traits Mendel studied, he c alled dominant those at showed up in the offspring and recessive those The question I will ask is: how much of the variability observed between different individuals is due to hereditary differences between them, and how much to differences in the environments under which the individuals developed?In most organisms, including man, genetics information is transmitted from mother to daughter cells and from one generation to the next by deoxyribonucleic acid (DNA). Knowledge of the heredity or inheritance of plants and animals is important in many phases of our life. The question I will ask is: How much of the variability observed between different individuals is due to hereditary differences between them, and how much to differences in the environments under which the individuals developed?The purpose of designing a unit on ? Heredity And Environment? is to help students learn more about themselves. They will learn why they develop into the kind of individual they are. The unit will d iscuss heredity traits and environmental conditions, chromosomes, DNA, studies of identical twins, and several diseases linked to heredity and environment. The students will do some hands on activities by constructing a model which represents DNA. They will explore plants with the exact same heredity and plants with different heredity.They will change the conditions in the environment to see the way the plant organisms with the same heredity may develop differently in different environments and why organisms with different heredity develop in the matter in which they do. Heredity is not the only thing that effects development. The environment also has an important effect. The unit can be taught to students in grades five through eight. The science and math teachers are encouraged to use a team teaching approach. Other features that will be included in the unit are content, lesson plans, resources, reading list and a bibliography.Genes and DNA DNA, short for deoxyribonucleic acid, ma kes up the genes that transmits hereditary traits. The DNA molecule looks like a long, twisted rope ladder. This is called the double helix. The ladder is made up of two coiled strands with rungs between them. The rungs are composed of pairs of chemicals in different combinations. Each combination carries instructions like the dot and dashes of the Morse Code. Each gene in the body is a DNA section with full set of instructions for guiding the formation of just one particular protein. The different proteins made by the genes direct the body? functions throughout a person? s life. DNA is made of six parts: a sugar, a mineral (phosphate), and four special chemicals called bases. These bases are represented as A;T;C; and G. Sugar and phosphate form the chains, or sides, of the staircase. The A;G;C and T bases form the steps. See figure 1. Each step is made of two pieces, which are always paired the same way. The A base always pairs with the T base. And the G base always pairs with the C base. Figure 1. DNA Structure (figure available in print form) DNA Reproduces Itself Two new identical DNAs are immediately formed.The A,G,C, and T bases on each chain attract loose bases found floating within the nucleus. Ts attract As and Cs attract Gs. The two new DNAs are just like the original DNA. Each strand directs the synthesis of a complementary strand. The replication of DNA is the key to heredity, the passing of traits from parents to offspring. DNA replication results in the formation of new reproductive cells. It also results in the formation of new cells, which is important for the growth of an organism. See Fig. 2. Figure 2. (figure available in print form) Watson-Crick?DNA Replication-Redrawn from version in Levine, Genetics, Holt, Rinehart, Winston, 1968. Chromosomes Genes and chromosomes provide the genetic link between generations. Chromosomes are strands of DNA and protein found in the nucleus of virtually every cell, but with few exceptions seen only during t he process of cell division. The number of chromosomes in a cell is characteristic of the species. Some have very few, whereas others may have more than a hundred. Ordinarily, every cell in the body of an organism contains the same number of chromosomes.The most important exception is found in the case of gametes where half the usual number is found. Human beings have 46 chromosomes in each cell, with the exception of the spermatozoa in males and the ova in females, each of which has 23 chromosomes. Human chromosomes occur in pairs, the total 46 consisting of 23 pairs; 22 pairs of autosomes which are non-sex determining chromosomes. The member of a pair are essentially identical, with the exception of sex chromosomes in males, and each pair is different from any other pair. Plants and animals inherit chromosomes from their parents.Each plant and animal cell has a set of chromosomes. Chromosomes, then, control the heredity of an organism. They carry the blueprint that determines what kind of organism will develop. Some Relationship Between Heredity And Environment Organisms can transmit some hereditary conditions to their offspring even if the parents do not show the trait. In the small, familiar fruit fly. Drosophila, there is a hereditary trait in which the wings curl up sharply if the files are raised at a temperature of 25 degrees Celsius. If, however, the files are raised at a lower temperature, such as 16 degrees Celsius then the trait rarely appears.The wings seem to be straight, and the flies look normal. The genetic trait is there, however, and will reappear in the next generation if the temperature returns to 25 degrees Celsius. See fig. 3. A similar type of inheritance appears in plants. In some types of corn the kernels will remain yellow until they are exposed to sunlight. Once exposed, the kernels become various shades of red and purple. Some traits do not appear to be affected by the environment. One of the first hereditary traits studied in huma ns was polydactyly. An individual with polydactyly has more than ten figures or toes.See fig. 4. This trait does not seem to be affected by the environment at all. Other human traits like color blindness, baldness, blood type, skin color, the ability to taste certain substances, the presence or absence of hairs on the middle of the fingers, and free or attached ear lobes do not seem to be influenced by the environment. (figure available in print form) Figure 3? This diagram shows how temperature affects curly-wing trait in Drosophila. If the third generation of curly-winged flies had been raised in 16? C environment.Source:Redrawn from Biological Science, Houghton, Mifflin Co. , Boston, 1963, p. 379. Figure 4? An example of polydactyly. Extra digits on either hands or feet are almost always abnormal in structure. (figure available in print form) Source: Biological Science, Houghton Mifflin Co. , Boston, 1963. p. 380. A common cited example of an environmental effect on phenotype is the coloring of Siamese Cats, although these cats have a genotype for dark fur, the enzymes that produce the dark coloring function best at temperatures below the normal body temperature of the cat.Siamese Cats are noted for the dark markings on their ears, nose, paws, tail, and all areas that have a low body temperature. If the hair on the cat? s belly is shaved and an ice pack is applied, the replacement hair will be dark. Likewise, a shaved tail, kept at higher than normal temperatures, would soon be covered with light colored fur. These changes are temporary, however, unless the ice pack or heat source is maintained permanently. The most celebrated effect of an environmental agent directly affecting the unborn, is that produced by the rubella virus.This German measles virus is capable of crossing the placenta from mother to child, and the prenatal infection, if it occurs early enough, may result in deafness and other damage to the child. Similarly, maternal infection with the ra re protozoan parasite Toxoplasma can cause serious congenital defects in the fetus, and the same has been suspected for Asian influenza. Another environmental factor is anoxia. Anoxia is a natural hazard of childbirth, and in most cases the infant makes a normal adjustment to it.When infants suffer from delayed respiration or asphyxia during birth, it is widely accepted that this is responsible for later difficulties such neurologic abnormalities. Warburton and Fraser have emphasized that the development of a fetus depends on a precise and extremely intricate system of interactions between two sets of hereditary factors and two environments, all acting at the same time on the growing baby. The mother and the fetus each have their own environment and their own genotype.

Media politics and intercention

Edward Bernays made important works in the field of public relation. His thoughts and views were pessimistic. It was clearly manifested in his theory that man must be controlled in order to attain democracy. He was known to be a follower of his uncle (Sigmund Freud). Freud’s ideas on man’s behavior were supported by Bernays. His works were greatly appreciated by critics. His outlooks also change traditional views on things such food and perception of women. Amusingly, he plays a vital role in the mass sales of cigarettes in the United States. Nowadays, Bernays’ theories have been applied in various political movements in gaining and achieving profit and power.   Moreover, his theories have great impact on American business because it deals mainly on acquiring profits. US administrations used Freud’s and Bernays’ political concepts to â€Å"exploit the subconscious factors that infuse fear and paranoia among the masses†¦ all in the name of democracy (Baroud, 2007).† Anti and pros are everywhere. Anti-democratic groups have made their leap to denounce democratic insights and perceptions. Anti-democratic movements were discontented about democratic advocates’ visions and objectives. Furthermore, Bernays’ influence is still gained its rewards. Without his ideas the concept of democracy, consumer citizenship and political states and all other aspects of politics were not yet unveiled up to now. Summary of The Convenience Denial A controversy on a CNN has been attached to it when a CNN’s new operators made some denial on the â€Å"liberal media† issue.   In addition to this, a former CNN executive made some defense on â€Å"War made Easy† film which seems to be the talk of the town during its release. Also Eason Jordan, CNN News chief executive made some boastful remarks about the network’s structure of professional military expertise. Eason Jordan was the executive during the extensive invasion US troops in Iraq. In line with Jordan’s comments, Inter Press released statements saying that his comment would surely â€Å"infuriate any veteran reporter who upholds the most basic and important tenet of journalistic profession: independence (Solomon, 2007).† Jordan was also criticized by his subordinate, Christina Davidson in connection to Jordan’s criticism on â€Å"War made Easy†. War made Easy is actually a film which gives the idea that â€Å"all of the cable networks were actively complicit in promoting the†Ã¢â‚¬â€the result of chronic biases rather than â€Å"journalistic laziness (Solomon, 2007).† CNN is known to be a form of â€Å"liberal media†. Jordan was accused of supporting Baghdad Government and even after the fall of Saddam Hussein. One important insight here is that â€Å"Often journalists blame government for the failure of the journalist to do independent reporting- we may be the news media, but we’re on the same side and the same page as the Pentagon (Solomon, 2007).† Reference: Baroud, Ramzy.

Torvald Helmers Monologue From A Dolls House

Torvald Helmer's Monologue From 'A Doll's House' Torvald Helmer, the male lead in A Doll’s House, can be interpreted in several ways. Many readers view him as a domineering, self-righteous control freak. Yet, Torvald can also be seen as a cowardly, misguided but sympathetic husband who fails to live up to his own ideal. In either case, one thing is for certain: He does not understand his wife. In this scene, Torvald reveals his ignorance. Moments before this monolog he declared he no longer loved his wife because she had brought shame and legal calamity to his good name. When that conflict suddenly evaporates, Torvald recants all of his hurtful words and expects the marriage to go back to â€Å"normal.† Unbeknownst to Torvald, his wife Nora is packing up her things during his speech. As he speaks these lines, he believes he is repairing her wounded feelings. In truth, she has outgrown him and plans to leave their home forever. The Monologue Torvald:(Standing at Nora’s doorway.) Try and calm yourself, and make your mind easy again, my frightened little singing-bird. Be at rest, and feel secure; I have broad wings to shelter you under. (Walks up and down by the door.) How warm and cozy our home is, Nora. Here is a shelter for you; here I will protect you like a hunted dove that I have saved from a hawks claws; I will bring peace to your poor beating heart. It will come, little by little, Nora, believe me. Tomorrow morning you will look upon it all quite differently; soon everything will be just as it was before. Very soon you wont need me to assure you that I have forgiven you; you will yourself feel the certainty that I have done so. Can you suppose I should ever think of such a thing as repudiating you or even reproaching you? You have no idea what a true mans heart is like, Nora. There is something so indescribably sweet and satisfying, to a man, in the knowledge that he has forgiven his wife- forgiven her freely, and with all his heart. It seems as if that had made her, as it were, doubly his own; he has given her a new life, so to speak, and she is in a way become both wife and child to him. So you shall be for me after this, my little scared, helpless darling. Have no anxiety about anything, Nora; only be frank and open with me, and I will serve as will and conscience both to you- . What is this? Not gone to bed? Have you changed your things?
