National Defense
National security, or national defence, is the security and defence of a sovereign state, including its citizens, economy, and institutions, which is regarded as a duty of government. Originally conceived as protection against military attack, national security is widely understood to include also non-military dimensions, including the security from terrorism, minimization of crime, economic security, energy security, environmental security, food security, and cyber-security. Similarly, national security risks include, in addition to the actions of other nation states, action by violent non-state actors, by narcotic cartels, and by multinational corporations, and also the effects of natural disasters. Governments rely on a range of measures, including political, economic, and military power, as well as diplomacy, to safeguard the security of a nation state. They may also act to build the conditions of security regionally and internationally by reducing transnational causes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photograph Of President Reagan In A Briefing With National Security Council Staff On The Libya Bombing - NARA - 198573
A photograph (also known as a photo, image, or picture) is an image created by light falling on a photosensitive surface, usually photographic film or an electronic image sensor, such as a CCD or a CMOS chip. Most photographs are now created using a smartphone/camera, which uses a lens to focus the scene's visible wavelengths of light into a reproduction of what the human eye would see. The process and practice of creating such images is called photography. Etymology The word ''photograph'' was coined in 1839 by Sir John Herschel and is based on the Greek φῶς (''phos''), meaning "light," and γραφή (''graphê''), meaning "drawing, writing," together meaning "drawing with light." History The first permanent photograph, a contact-exposed copy of an engraving, was made in 1822 using the bitumen-based "heliography" process developed by Nicéphore Niépce. The first photographs of a real-world scene, made using a camera obscura, followed a few years later at Le Gras, Fra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nation State
A nation state is a political unit where the state and nation are congruent. It is a more precise concept than "country", since a country does not need to have a predominant ethnic group. A nation, in the sense of a common ethnicity, may include a diaspora or refugees who live outside the nation state; some nations of this sense do not have a state where that ethnicity predominates. In a more general sense, a nation state is simply a large, politically sovereign country or administrative territory. A nation state may be contrasted with: * A multinational state, where no one ethnic group dominates (such a state may also be considered a multicultural state depending on the degree of cultural assimilation of various groups). * A city-state, which is both smaller than a "nation" in the sense of "large sovereign country" and which may or may not be dominated by all or part of a single "nation" in the sense of a common ethnicity. * An empire, which is composed of many countries (po ...

Nuclear Proliferation
Nuclear proliferation is the spread of nuclear weapons, fissionable material, and weapons-applicable nuclear technology and information to nations not recognized as " Nuclear Weapon States" by the Treaty on the Non-Proliferation of Nuclear Weapons, commonly known as the ''Non-Proliferation Treaty'' or ''NPT''. Proliferation has been opposed by many nations with and without nuclear weapons, as governments fear that more countries with nuclear weapons will increase the possibility of nuclear warfare (up to and including the so-called countervalue targeting of civilians with nuclear weapons), de-stabilize international or regional relations, or infringe upon the national sovereignty of nation states. Four countries besides the five recognized Nuclear Weapons States have acquired, or are presumed to have acquired, nuclear weapons: India, Pakistan, North Korea, and Israel. None of these four is a party to the NPT, although North Korea acceded to the NPT in 1985, then withdrew in 200 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Social Exclusion
Social exclusion or social marginalisation is the social disadvantage and relegation to the fringe of society. It is a term that has been used widely in Europe and was first used in France in the late 20th century. It is used across disciplines including education, sociology, psychology, politics and economics. Social exclusion is the process in which individuals are blocked from (or denied full access to) various rights, opportunities and resources that are normally available to members of a different group, and which are fundamental to social integration and observance of human rights within that particular group (e.g., housing, employment, healthcare, civic engagement, democratic participation, and due process). Alienation or disenfranchisement resulting from social exclusion can be connected to a person's social class, race, skin color, religious affiliation, ethnic origin, educational status, childhood relationships, living standards, and or political opinions, and app ...

Economic Inequality
There are wide varieties of economic inequality, most notably income inequality measured using the distribution of income (the amount of money people are paid) and wealth inequality measured using the distribution of wealth (the amount of wealth people own). Besides economic inequality between countries or states, there are important types of economic inequality between different groups of people. Important types of economic measurements focus on wealth, income, and consumption. There are many methods for measuring economic inequality, the Gini coefficient being a widely used one. Another type of measure is the Inequality-adjusted Human Development Index, which is a statistic composite index that takes inequality into account. Important concepts of equality include equity, equality of outcome, and equality of opportunity. Whereas globalization has reduced global inequality (between nations), it has increased inequality within nations. Income inequality between nations peak ...

Climate Change
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causing m ...

Transnationalism
Transnationalism is a research field and social phenomenon grown out of the heightened interconnectivity between people and the receding economic and social significance of boundaries among nation states. Overview The term "trans-national" was popularized in the early 20th century by writer Randolph Bourne to describe a new way of thinking about relationships between cultures. However, the term itself was coined by a colleague in college. Merriam-Webster Dictionary states 1921 was the year the term "transnational" was first used in print, which was after Bourne's death. Transnationalism as an economic process involves the global reorganization of the production process, in which various stages of the production of any product can occur in various countries, typically with the aim of minimizing costs. Economic transnationalism, commonly known as globalization, was spurred in the latter half of the 20th century by the development of the internet and wireless communication, as wel ...

Diplomacy
Diplomacy comprises spoken or written communication by representatives of states (such as leaders and diplomats) intended to influence events in the international system.Ronald Peter Barston, ''Modern diplomacy'', Pearson Education, 2006, p. 1 Diplomacy is the main instrument of foreign policy which represents the broader goals and strategies that guide a state's interactions with the rest of the world. International treaties, agreements, alliances, and other manifestations of international relations are usually the result of diplomatic negotiations and processes. Diplomats may also help to shape a state by advising government officials. Modern diplomatic methods, practices, and principles originated largely from 17th-century European custom. Beginning in the early 20th century, diplomacy became professionalized; the 1961 Vienna Convention on Diplomatic Relations, ratified by most of the world's sovereign states, provides a framework for diplomatic procedures, methods, and co ...

Military
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. It is typically authorized and maintained by a sovereign state, with its members identifiable by their distinct military uniform. It may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of the military is usually defined as defence of the state and its interests against external armed threats. In broad usage, the terms ''armed forces'' and ''military'' are often treated as synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include both its military and other paramilitary forces. There are various forms of irregular military forces, not belonging to a recognized state; though they share many attributes with regular military forces, they are less often referred to as simply ''military''. A nation's military may ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Economic Power
Economic power refers to the ability of countries, businesses or individuals to improve living standards. It increases their ability to make decisions on their own that benefit them. Scholars of international relations also refer to the economic power of a country as a factor influencing its power in international relations. Definition Economists use several concepts featuring the word power: * Market power is the ability of a firm to profitably raise the market price of a good or service over marginal cost. ** Monopoly power is a strong form of market power—the ability to set prices or wages unilaterally. This is the opposite of the situation in a perfectly competitive market in which supply and demand set prices. * Purchasing power, i.e. the ability of any amount of money to buy goods and services. Those with more assets, or more correctly net worth, have more power of this sort. The greater the liquidity of one's assets, the greater one's purchasing power is. Purchasing p ...

Political Power
In social science and politics, power is the social production of an effect that determines the capacities, actions, beliefs, or conduct of actors. Power does not exclusively refer to the threat or use of force (coercion) by one actor against another, but may also be exerted through diffuse means (such as institutions). Power may also take structural forms, as it orders actors in relation to one another (such as distinguishing between a master and a slave), and discursive forms, as categories and language may lend legitimacy to some behaviors and groups over others. The term ''authority'' is often used for power that is perceived as legitimate or socially approved by the social structure. Power can be seen as evil or unjust; however, power can also be seen as good and as something inherited or given for exercising humanistic objectives that will help, move, and empower others as well. Scholars have distinguished between soft power and hard power. Theories Five bases ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural Disaster
A natural disaster is "the negative impact following an actual occurrence of natural hazard in the event that it significantly harms a community". A natural disaster can cause loss of life or damage property, and typically leaves some economic damage in its wake. The severity of the damage depends on the affected population's resilience and on the infrastructure available. Examples of natural hazards include: avalanche, coastal flooding, cold wave, drought, earthquake, hail, heat wave, hurricane (tropical cyclone), ice storm, landslide, lightning, riverine flooding, strong wind, tornado, typhoon, tsunami, volcanic activity, wildfire, winter weather. In modern times, the divide between natural, man-made and man-accelerated disasters is quite difficult to draw. Human choices and activities like architecture, fire, resource management or even climate change potentially play a role in causing "natural disasters". In fact, the term "natural disaster" has been called a misnom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
